This study investigates the expression and functional significance of mitochondrial ribosomal protein S12 (MRPS12) within NSCLC pathogenesis. The Cancer Genome Atlas dataset reveals a significant association between MRPS12 overexpression and unfavorable clinical outcomes in NSCLC patients. Single-cell RNA sequencing data unequivocally confirm MRPS12 overexpression across diverse NSCLC cancer cell populations. MRPS12 is also upregulated in locally-treated NSCLC tissues. shRNA-mediated gene silencing or CRISPR-Cas9-mediated gene knockout (KO) of MRPS12 impaired mitochondrial function, resulting in a reduction in oxygen consumption rate, marked declines of complex I activity and ATP levels, mitochondrial membrane depolarization, and an increase in reactive oxygen species production in NSCLC cells. Moreover, MRPS12 silencing or knockout attenuated cell viability, proliferation, and migratory capacity, while inducing apoptotic cell death in various NSCLC cell types. Conversely, ectopic MRPS12 overexpression conferred a pro-tumorigenic phenotype to NSCLC cells. In vivo studies demonstrated that MRPS12 silencing markedly inhibited the growth of subcutaneous xenografts derived from primary NSCLC cells in nude mice. The MRPS12-silenced NSCLC xenografts exhibited decreased ATP levels, elevated oxidative injury, diminished proliferation, inhibited Akt-mTOR activation and an increase in apoptosis. These findings support the important role of MRPS12 in supporting mitochondrial function and driving the malignant progression of NSCLC.

Background:The management of esophageal anastomotic fistula continues to be a significant clinical challenge in the field of esophageal surgery. With rapid advances in material science, selecting appropriate biomaterials to enhance anastomotic healing and reduce the incidence of anastomotic fistula has emerged as a promising strategy to address the issues. The aim of this study was to investigate the prevention of anastomotic fistula by reinforcing the anastomosis with suitable biomaterial patches. Methods:Forty large, healthy adult New Zealand white rabbits were randomized into the experimental group (n=20) and the control group (n=20). An animal model of cervical esophageal anastomosis was established using the esophagectomy anastomosis method. The esophageal anastomoses of the rabbits in the experimental group were completely covered with hydrogel biomaterial patches loaded with basic fibroblast growth factor (bFGF) intraoperatively. Four weeks after surgery, the incidence of anastomotic fistula was observed, and tissue samples were obtained from the esophageal anastomosis site for histologic and immunofluorescent detection. Results:An animal model of cervical esophageal incision and anastomosis was successfully established in rabbits, and the incidence of anastomotic fistula in the experimental group was lower than that in the control group at the end of the experiment (1/18 versus 7/19; P<0.05). The esophageal anastomosis tensile test showed that the anastomosis in the experimental group had higher mechanical strength than that in the control group (6.49±0.17 versus 6.33±0.12 N; P<0.05). Histological examination of the anastomotic specimens showed that the tissue layers of the esophageal anastomoses in the experimental group were clear, and fibroblast proliferation and collagen fiber secretion were greater than those in the control group. Immunofluorescence showed that fibroblast proliferation was significantly increased in the perianastomotic tissues of the experimental group compared to that of the control group. Conclusions:The application of hyaluronic acid methacrylate (HAMA) hydrogel biomaterial patches loaded with bFGF in esophageal surgery improved the mechanical strength of the esophageal anastomosis, facilitated fibroblast proliferation and collagen secretion, and could promote the growth of the tissues around the esophageal anastomosis. It may thus serve as a novel therapeutic approach for reducing the incidence of anastomotic fistula in esophageal cancer.

Background:Recently, minimally invasive surgical modalities have become the mainstream approach for the treatment of esophageal cancer, but the incidence rate of anastomotic leak (AL) has not significantly decreased. Compared to intrathoracic anastomoses, cervical anastomotic leaks (CALs) occur at a higher rate. However, there is still a lack of consensus regarding the local management for CALs. In recent years, we have innovated an irrigation and drainage technique for patients with CALs. The aim of this article is to investigate the therapeutic effect of this novel technique. Methods:The current study was designed as a retrospective study. Patients with CALs in Shanghai Changzheng Hospital were included consecutively. Data regarding healing time (HT), frequency of dressing changes (DC), post-operative hospital stay, mortality, morbidity, as well as laboratory indicators, such as white blood cell count (WBC), C-reactive protein (CRP), procalcitonin (PCT), and interleukin-6 (IL-6) were recorded. Results:The current study included a total of 53 patients with CALs. Among them, 26 patients received conventional DC treatment (DC group), while 27 patients were treated with irrigation and drainage treatment (IDT) group. IDT significantly expedited the HT of CALs (45 vs. 22 days, P<0.01), reduced the frequency of DC (2.6 vs. 1.5 times/day, P<0.01), shortened the length of post-operative hospital stay (76.5 vs. 43 days, P<0.01), and decreased the mortality rate of patients (15.4% vs. 0%, P<0.05). Additionally, the incidence of sepsis (23.1% vs. 3.7%, P<0.05) and pneumonia (30.8% vs. 7.4%, P<0.05) significantly decreased in the IDT group. Laboratory tests indicated that IDT significantly reduced the CRP and IL-6 levels on the 3rd and 7th days of treatment. Conclusions:The irrigation and drainage technique is an effective treatment for CALs and merits broad implementation within clinical practice.

Background:Esophageal malignancies have a high morbidity rate worldwide, and minimally invasive surgery has emerged as the primary approach for treating esophageal cancer. In recent years, there has been increasing discussion about the potential of employing inflatable mediastinoscopic and laparoscopic approaches as an option for esophagectomy. Building on the primary modification of the inflatable mediastinoscopic technique, we introduced a secondary modification to further minimize surgical trauma.Methods:We conducted a retrospective analysis of patients who underwent inflatable mediastinoscopy combined with laparoscopic esophagectomy at the Second Affiliated Hospital of Naval Medical University from March 2020 to March 2023. The patients were allocated to the following two groups: the traditional (primary modification) group, and the secondary modification group. Operation times, intraoperative bleeding, and postoperative complications were compared between the groups.Results:The procedure was successfully performed in all patients, and conversion to open surgery was not required in any case. There were no statistically significant differences in the surgical operation time, intraoperative bleeding, number of dissected lymph nodes, and rate of postoperative anastomotic leakage between the two groups. However, a statistically significant difference was observed in the length of the mobilized esophagus between the two groups. The mobilization of esophagus to the level of diaphragmatic hiatus via the cervical incision was successfully achieved in more patients in the secondary modification group than the primary modification group.Conclusions:Inflatable mediastinoscopy combined with single-incision plus one-port laparoscopic esophagectomy is a safe and effective surgical procedure. The use of a 5-mm flexible endoscope, ultra-long five-leaf forceps, and LigaSure Maryland forceps facilitates esophageal mobilization and lymph node dissection through a single cervical incision.

It is necessary to study the kinematics of landslide prior to its failure for accurately estimating the time of landslide instability. Based on a spring block model, considering the Dieterich Ruina's friction, the kinematic displacement and velocity of landslide along the slip surface are analyzed under quasistatic approximation. A algebraic relationship including three parameters between the displacement (or velocity) and time is obtained, and then applied to two typical landslides: Vaiont in Italy, and Maoxian in China. The results show that the proposed spring block friction model can well describe the kinematic data of landslides before their failure. If the effective data of displacement can be obtained to determine the three parameters above, this simple physical model could be used to estimate the time of landslide instability. Based on this spring block friction model, we also provide a clear physical basis for the usual inverse velocity method of the landslide warning, and point out that it can only to be used for the monitoring velocity data near the landslide failure.

The interaction between the mantle transition zone and the Pacific subduction stagnant slab beneath Northeast Asia has an important influence on the regional deep material migration and tectonic evolution. Based on the broadband waveform data of two deep earthquakes in the sea of Okhotsk and Kuril Islands recorded by the China National Seismic Network (CNSN), we find a new clear P-wave triplication related to a special interface above the 660-km discontinuity. Through the waveform fitting and grid searching of the observed triplicated waveforms, we obtain the fine velocity structure near the 660-km discontinuity beneath the edge of Northeast Asia. Our results reveal that: (1) there is a high-velocity anomaly layer above the 660-km discontinuity beneath Northeast Asia edge, which has a sharp upper interface at depth of 455 similar to 510 km with a P-wave velocity anomaly of 2%similar to 4. 5%; (2) the 660-km discontinuity shows small velocity increment and slight depressions of 0 similar to 15 km; (3) there exists good consistency between the depression of the 660-km discontinuity and the upper interface of the high-velocity layer, showing the morphological characteristics deepening trend from west to east and also from south to north. Combining with the results of previous studies, we speculate that the uneven impact of the Northwest Pacific subduction slab on the lowermost upper-mantle due to the heterogeneity of the Japan-Kuril trench retraction rate is the main cause for the overall north-south difference; possible flattening and stacking of the stagnant slab in the mantle transition zone may induce a shallower upper interface of the slab in the west side than that in the east side; the velocity anomaly characteristics at the upper interface of the stagnant slab indicate that subducted sediments may reach the mantle transition zone and then form topaz-bearing mineralogical assemblage through dehydration and phase transformation.

Abstract To explore the safety and feasibility of wireless thoracoscope in thoracic surgery. A retrospective analysis was made of all the clinical data of 90 patients with thoracoscope lung resection, from April to August 2021, Shanghai changzheng hospital thoracic minimally invasive center. Compared the thoracoscope preparation time, picture resolution, picture delay, surgeon comfort level, assistant comfort level between the wireless thoracoscope group and wired thoracoscope group. The thoracoscopic preparation time of the wireless thoracoscope group was significantly shorter than that of the wired group (26.66 ± 6.04 vs 62.14 ± 10.07, p < 0.0001). Comfort level of the surgeon (4.64 ± 0.48 vs 3.77 ± 0.42, p < 0.001) and the comfort level of the assistant (4.85 ± 0.36 vs 3.88 ± 0.32, p < 0.001) of the wireless thoracoscope group were higher than that of the wired thoracoscope group. There were no statistically significant differences in video sharpness (4.64 ± 0.48 vs 4.74 ± 0.44, p = 0.31). Although there was one case picture delay in wireless group, it was caused by low power which could be dealt with by a good charge before surgery. The wireless thoracoscope has the advantages of short preparation time, high comfort for the surgeon and the assistant, no less than the wired thoracoscope in picture resolution and picture delay. Wireless connection is more convenient and portability, which is worthy of further application in clinical practice.

Background:With the popularity of high-resolution computed tomography (HRCT), more and more pulmonary nodules are being discovered. Video-assisted thoracoscopic surgery (VATS) has become the first choice for surgical treatment of pulmonary nodules. The use of accurate preoperative localization is crucial for successful resection in VATS. At present, there are many kinds of preoperative localization methods, but there are certain disadvantages. This study aimed to evaluate the feasibility and safety of mixed reality (MR)-guided pulmonary nodules localization, which is a new method that can benefit patients to a greater extent.Methods:By constructing an animal model of pulmonary nodules localization, 28 cases of pulmonary nodules were located by MR-guided localization. We recorded the localization accuracy, localization time, insertion attempts, and incidence of complications related to localization under MR-guidance.Results:All 28 nodules were successfully located: the deviation of MR-guided localization was 5.71±2.59 mm, localization time was 8.07±1.44 min, and insertion attempts was 1. A pneumothorax and localizer dislodgement occurred in 1 case, respectively.Conclusions:Since preoperative localization is critical for VATS resection of pulmonary nodules, we investigated a new localization method. As indicated by our study, MR-guided localization of pulmonary nodules is feasible and safe, which is worthy of further research and promotion. We have also registered corresponding clinical trials to further investigate and help to improve our understanding of this technique.

Objective To investigate the safety and efficacy of glasses-free three-dimensional (3D) thoracoscopic surgery in minimally invasive esophagectomy (MIE). Methods The clinical data of 98 patients, including 81 men and 17 women aged 45–77 years, with esophageal squamous cell carcinoma who underwent minimally invasive thoracoscopic esophagectomy from January 2017 to December 2019 [3 years, with clinical follow-up time: 1 year~4 years (2017.01–2020.12)] were retrospectively analyzed. Patients were divided into two groups according to different surgical methods including a glasses-free 3D thoracoscopic group (G-3D group: 38 patients) and a two-dimesional (2D) thoracoscopic group (2D group: 60 patients). The clinical outcome of the two groups were compared. Results The operation time of the thoracoscopic part in the G-3D group was significantly shorter than that in the 2D group (P<0.05). The total number of lymph node dissection in the G-3D group was more than that in the 2D group (P<0.05). The thoracic indwelling time, postoperative hospital stay, severe pulmonary infection, arrhythmia, anastomotic leakage, chylothorax, and recurrent laryngeal nerve injury were not significantly different between the two groups (P>0.05). There was also no significant difference between the two groups on the progression-free survival (P>0.05). Conclusion Glasses-free 3D thoracoscopic surgery for esophageal cancer is a safe and effective surgical procedure. Compared with 2D thoracoscopic MIE, glasses-free 3D thoracoscopic MIE for esophageal cancer has higher safety, more lymph node dissection, and higher operation efficiency through the optimized surgical operations. We believe that glasses-free 3D thoracoscopy for MIE is worthy of clinical promotion.

The collision between the Indian and Eurasian plates since the Cenozoic causes the formation of the Himalayan orogenic belt and Tibetan Plateau, and the Indian plate enters into the deep mantle beneath the Burma arc subduction zone in eastern Himalayan syntaxis. Study on mantle discontinuities is helpful to understand the collision-subduction process of the Indian continental lithosphere and its influence on the upper mantle structures. In this study, we select three intermediate-depth earthquakes occurred in the Burma arc, and retrieve broadband seismograms based on several dense networks/arrays in Europe and Alaska of America. Using the N-th root slant stack method (N= 1,4), we extract SdP phases converted at mantle discontinuities below the sources. We find that the depths of the 410-km discontinuity appear at 392 similar to 407 km with an average of 400 km and an average uplift of 10 km compared with the IASP91 model. We suggest that the Indian slab has penetrated across the 410-km discontinuity and entered into the mantle transition zone, and the uplifts of the 410-km discontinuity are likely induced by the cold subducted slab. The depths of X-discontinuity in our study area appear at 289 similar to 314 km with an average of 306 km. We infer that the X-discontinuity may relate to the coesite to stishovite transformation in the ultrahigh pressure metamorphic rocks under the deep subduction of the continental crust.

Background:With uniportal video-assisted thoracoscopic surgery (VATS) becoming mainstream, how to make the incision cosmetic has attracted much attention. This study aimed to introduce a new traceless method for cosmetic closure of the incision and a special procedure for chest tube fixation after uniportal VATS and to evaluate the feasibility, effectiveness, and safety of this new technique.Methods:In this retrospective study, a total of 258 consecutive patients who underwent uniportal VATS were included. Among them, 127 patients were treated with a conventional method, and 131 patients were treated with a new method.Results:Patients in the new method group had a significantly less incidence of subcutaneous emphysema after the chest tube was removed. The incidence of pneumothorax after the chest tube was removed and fat liquefaction of chest incision was not significantly different between the two groups. No differences in the incidence of pneumothorax after chest tube removal and fat liquefaction of postsurgical incision were found between the two groups. Additionally, there was also no significant difference in follow-up items.Conclusions:Taken together, our results showed that this new method for minimally invasive incision closure and chest tube fixation after uniportal VATS was as feasible, effective, and safe as the conventional one but more cosmetic.

N6-Methyladenosine (m6A) RNA methylation is the most prevalent post-transcriptional modification mechanism in humans and plays an important role in the pathogenesis of various tumors. However, the investigation of m6A modification in Esophageal squamous cell carcinoma (ESCC) remains in its infancy. Transcriptome-wide m6A changes were profiled using human m6A epitranscriptomic microarrays in ESCC tissues and adjacent normal tissues. Differentially m6A-methylated mRNAs, lncRNAs and Mid-size ncRNAs were identified, followed by functional enrichment analysis. Moreover, we also establish a competing endogenous RNA (ceRNA) network based on the m6A-related lncRNA growth arrest specific 5 (GAS5) specific transcript（NR_152533）. The results suggested that RALYL may be a target gene for miR-3912-5p, and that GAS5 regulated RALYL expression by binding to miR-3912-5p.

BackgroundIt still remains unclear whether subxiphoid video-assisted thoracoscopic surgery (SVATS) thymectomy is safe and reasonable. This meta-analysis aims at assessing the effectiveness and safety of SVATS for thymoma in comparison with that of intercostal video-assisted thoracoscopic surgery (IVATS) thymectomy.MethodsAll the relevant data systematically analyzed in this thesis were retrieved from PubMed, the Cochrane Library, web of science, EMBASE, and ClinicalTrials.gov. The time span for data retrieval was from the date of database establishment to March 2022. The outcome indicators include operation time, intraoperative blood loss, duration of postoperative drainage, postoperative hospital days, visual analogue scale (VAS) score on the day of operation, VAS score on postoperative day 3, and VAS score on postoperative day 7; postoperative complications were analyzed in our meta-analysis.ResultsIn 13 studies of this paper, there were 1,198 cases included. Among them, 563 cases were treated by SVATS thymectomy and 635 cases by IVATS thymectomy. There was no significant difference in the operation time [113.38 vs. 119.91 min, 95% confidence interval (CI): −0.70–0.15, p = 0.20) and the incidence of intraoperative and postoperative complications (RR = 0.82, 95% CI: 0.58–1.15, p = 0.25) between SVATS thymectomy and IVATS thymectomy. However, SVATS thymectomy significantly reduced the amount of intraoperative blood loss (47.68 vs. 66.69 mL, SMD = −0.57, 95% CI: −0.95 to −0.18, p = 0.004), postoperative drainage days (2.12 vs. 2.72 days, SMD = −0.46, 95% CI: −0.74 to −0.18, p = 0.001), postoperative hospital stays (4.53 vs. 5.91 days, SMD = −0.64, 95% CI: −0.96 to −0.31, p = 0.0001), and VAS scores after the operation.DiscussionSVATS thymectomy is safe and feasible, and the perioperative effect is better than IVATS thymectomy to a certain extent, which is worthy of popularization and further research.Systematic Review Registration:https://www.crd.york.ac.uk/PROSPERO/

Background and objective Transcervical inflatable mediastinoscopic esophagectomy (TIME) is a novel method of minimally invasive esophagectomy (MIE) for esophageal cancer. However, whether TIME is effective and feasible as conventional MIE remains unclear. This study aimed to evaluate the efficacy of TIME by comparing it with thoracoscopic esophagectomy (TE). Methods Surgical outcomes and relapse-free survival (RFS) rates of patients with local early- or intermediate-stage thoracic esophageal squamous cell carcinoma that underwent TIME or TE from January 2017 to December 2019 were analyzed in this retrospective study. Propensity score matching was used to control the confounding factors. Results The mean operation time in TIME was shorter than that in TE (p < 0.05). Patients in the TIME group achieved postoperative ambulation earlier than those in the TE group (p < 0.05). The rate of pulmonary complications was lower in TIME than in TE (p < 0.05). The number of lymph nodes harvested during surgery and the RFS rates of two groups did not have significant differences. Conclusion TIME may be a feasible and safe method to treat local early- and intermediate-stage thoracic esophageal squamous cell carcinoma effectively and it could be a supplementary surgical method of TE for patients with poor pulmonary function or cannot undergo TE.

BACKGROUND:It still remains unclear whether three-dimension (3D) video-assisted thoracoscopic surgery (VATS) for esophageal cancer is safe and reasonable. This meta-analysis aims at assessing the effectiveness and safety of 3D VATS for esophageal cancer in comparison with that of two-dimension (2D) VATS.METHODS:All the relevant data systematically analyzed in this thesis is from PubMed, Embase, The Cochrane Library, Web of Science and clinicaltrials.gov, and the time span for retrieval is from the date of the database establishment to February 2021. The research on the efficacy and safety of 3D VATS for esophageal cancer and 2D VATS is consistent with our meta-analysis. Continuous variables and dichotomy variables are compared using odds ratio, average or standard average differences with 95% confidence interval (95% CI), and P values, respectively.RESULTS:In five studies of this paper, there were 553 patients in total (3D VATS group, n=266 and 2D VATS group, n=287). Patients in the 3D group had shorter operation time [standardized mean difference (SMD) =-0.99, 95% CI: -1.66 to -0.32; P=0.004], and less bleeding (SMD =-0.88, 95% CI: -1.66 to -0.10; P=0.03) than those in the 2D group. The total amount of dissected lymph node and post-operative complications in the 2D group and the 3D group were nearly the same, showing no significant difference.DISCUSSION:The results of this meta-analysis showed that 3D VATS for esophageal cancer will be more applied and developed in the future.REGISTRATION NUMBER OF PROSPERO:CRD42021238863.

Background Esophagectomy via transcervical incision inflatable single-port mediastinoscope combined with laparoscopy as a safe and feasible minimally invasive technique has gained attention recently. But the occurrence of Intraoperative events is inevitable. It’s necessary to investigate and discuss the intraoperative events and countermeasures during operation. Methods Intraoperative events were retrospectively reviewed in 60 patients who underwent esophagectomy via transcervical incision inflatable single-port mediastinoscope combined with laparoscopy in the recent 3 years. Results There was no perioperative death and no aortic or bronchial injury. Bronchial artery injury occurred in 2 cases (3.34%), bronchial artery combined with azygos vein hemorrhage occurred in 1 case (1.67%). The pleura were injured in 3 cases (5%). Recurrent laryngeal nerve injury was noticed in 7 cases (11.67%). Thoracic duct injury occurred in 1 case (1.67%). Conclusions As a new surgical method, esophagectomy via transcervical incision inflatable single-port mediastinoscope combined with laparoscopy is considered safe and feasible, but requires improvement when compared with traditional surgical methods. Due to the influence of surgical space and with experienced surgeons, the incidence of intraoperative events such as intraoperative bleeding and thoracic duct injury is not dominant when compared with the traditional surgical methods. Thoracic surgeons should continuously improve their clinical knowledge as well as skills. Careful preoperative examination and evaluation of the patients, being familiar with the anatomical structure and various methods, wise selection of energy devices and calmly dealing with all kinds of events are the key factors for successful surgeries with fewer intraoperative events.

Central precocious puberty (CPP), largely caused by germline mutations in the MKRN3 gene, has been epidemiologically linked to cancers. MKRN3 is frequently mutated in non-small cell lung cancers (NSCLCs) with five cohorts. Genomic MKRN3 aberrations are significantly enriched in NSCLC samples harboring oncogenic KRAS mutations. Low MKRN3 expression levels correlate with poor patient survival. Reconstitution of MKRN3 in MKRN3-inactivated NSCLC cells directly abrogates in vitro and in vivo tumor growth and proliferation. MKRN3 knockout mice are susceptible to urethane-induced lung cancer, and lung cell-specific knockout of endogenous MKRN3 accelerates NSCLC tumorigenesis in vivo. A mass spectrometry-based proteomics screen identified PABPC1 as a major substrate for MKRN3. The tumor suppressor function of MKRN3 is dependent on its E3 ligase activity, and MKRN3 missense mutations identified in patients substantially compromise MKRN3-mediated PABPC1 ubiquitination. Furthermore, MKRN3 modulates cell proliferation through PABPC1 nonproteolytic ubiquitination and subsequently, PABPC1-mediated global protein synthesis. Our integrated approaches demonstrate that the CPP-associated gene MKRN3 is a tumor suppressor.
