Background: Spinalfusion has shown satisfactory efficacy in the treatment of adult patients with low-grade isthmic spondylolisthesis (LGIS), however, the efficacy of direct repair (DR) for LGIS has not been established, and there is as yet a few reports on it. Objective: To assess the clinical efficacy of DR with the pedicle screw-rod-hook (PSRH) fixation and transforaminal lumbar interbody fusion (TLIF) in adult patients with symptomatic LGIS. Methods: A total of 140 adult patients with LGIS were enrolled from April 2009 to December 2018, of whom, 69 cases underwent DR using the PSRH system and 71 cases underwent TLIF, with clinical efficacy evaluated comparatively using clinical and radiological assessments. Results: The patients in both groups showed satisfactory pain relief efficacy and improvement in lumbar spine function. Bone fusion rate was 97.10% in the DR group vs. 100% in the TLIF group. The range of motion (ROM) of the surgical segment was significantly decreased from 13.72±6.73 preoperatively to 11.60±9.70 at the final follow-up (FFU) in the DR group and lost in the TLIF group, however, that of the upper intervertebral space (UIS)in each group or between groups before and after operation did not differ significantly. Conclusion: Both DR and TLIF are effective for adult patients with LGIS. As compared with TLIF, DR is more effective in preserving the ROM of the operative segment yet with less impact on adjacent segments.
Objective To investigate the clinical characteristics and identify risk factors of postoperative recurrence in thoracolumbar tuberculosis, aiming to assess clinical significance and propose management strategies. Methods Retrospective review of 69 patients' medical records with postoperative recurrence of thoracolumbar tuberculosis from 2006 to 2019, including demographics, clinical presentations, radiographic data, drug susceptibility, laboratory results, and recurrence patterns. Results The study included 40 males and 29 females, with a mean age of 36.1 ± 14.2 years at initial surgery and 37.5 ± 14.5 years at recurrence. Manifestations included pain (55.1%), sinus tracts (47.8%), and neurological deficits (37.7%). Radiographic assessments showed paravertebral (89.9%) and flowing abscesses (37.7%). Drug resistance was present in 41.5% of cases. Inflammatory markers were elevated in most patients, with anemia and hypoalbuminemia frequently observed. Most recurrences occurred within 24 months post-surgery, with a maximum interval of 84 months, and 37.7% had multiple recurrences. Conclusion Postoperative recurrence in thoracolumbar tuberculosis is multifactorial, linked to drug-resistant tuberculosis, inconsistent medication adherence, poor nutrition, inadequate immobilization, and systemic tuberculosis infections. Optimal postoperative surveillance and clinical management necessitate a focus on inflammatory markers, advanced imaging, diligent patient education, and rigorous follow-up to diminish recurrence rates and enhance patient outcomes.
Objective:To investigate the alleviating effect and potential mechanism of TRPC6 on renal ischemic reperfusion injury (RIRI).Methods:After establishing oxygen-glucose deprivation/reoxygenation, OGD/R HK-2 model cells and ischemia-reperfusion (I/R) model mice, the expression levels of IL-1β and IL-18 in model cells or mice were detected by using ELISA kits, whilst the expression of caspase-1 was examined by RT-qPCR, Western blot, and immunohistochemistry. And the cell viability and pyroptosis were determined by CCK-8 assay and flow cytometry. Moreover, the interaction between TRPC6 and miR-214 was identified by dual-luciferase reporter assay.Results:The expression of TRPC6 was observably increased in OGD/R HK-2 cells and I/R model mice. Meanwhile, down-regulation of caspase-1 enhanced the vitality of OGD/R HK-2 cells and inhibited inflammation and pyroptosis. Overexpression of TRPC6 could alleviate renal injury and down-regulate caspase-1 in I/R model mice. TRPC6 could down-regulate caspase-1 partly by regulating miR-214, thereby improving RIRI.Conclusion:TRPC6 alleviates RIRI by targeting miR-214 to down-regulate caspase-1 expression. The TRPC6/miR-214/caspase-1 regulatory pathway may provide key clues for the therapy of RIRI.

Background:Renal ischemic reperfusion injury (RIRI) is the most hackneyed cause of acute renal injury with high incidence. As a slit diaphragm (SD), TRPC6 (transient receptor potential channel 6) can maintain the structure and function of glomerular podocytes, and its activation has been reported to prominently alleviate ischemia reperfusion (I/R). However, the specific mechanism of TRPC6 in RIRI is uncertain.Methods:The TRPC6 specific shRNA or overexpressing plasmid was used to decrease or increase TRPC6 level in HK-2 cells, respectively. Subsequently, the OGD/R (oxygen-glucose deprivation and re-oxygenation) HK-2 cells and RIRI model rats was established to examine the effect of TRPC6 in RIRI in vitro. After processing, viability was confirmed with MTT; cell necrosis was analyzed with flow cytometry; necrosis and autophagy-related proteins were verified with Western blot; free Zn2+ was tested with an Zn2+ fluorescent probe; and cell autophagy was monitored with MDC (monodansylcadaverine) method. Furthermore, TRPC6 agonist (OGA) or TRPC6 inhibitor (SKF96365) were introduced to increase or inhibit the activity of TRPC6 in RIRI model rats, and the kidney injury was assessed with H&E staining and RIP1 and PARP-1 expressions were examined with IHC (immunohistochemistry) staining.Results:Our results verified TRPC6 could markedly enhance viability, Zn2+ influx, and autophagy, and suppressed necrosis in OGD/R HK-2 cells. In addition, increase of Zn2+ or autophagy activation produced similar results to TRPC6 overexpression in viability, autophagy, and necrosis of OGD/R HK-2 cells. Rescue experiment results also showed TRPC6 could prevent necrosis and facilitate Zn2+ influx and autophagy of OGD/R HK-2 cells by inducing Zn2+ influx and autophagy. Moreover, TRPC6 could ameliorate kidney injury, block necrosis, and enhance autophagy in RIRI model rats by promoting Zn2+ influx and autophagy.Conclusions:TRPC6 could prevent necrosis and induce autophagy to alleviate RIRI by accelerating Zn2+ influx and autophagy. This shows TRPC6/Zn2+ influx/autophagy might be a novel therapeutic strategy for RIRI.
Objective Type C fracture is a complete intra-articular fracture, and the mainstay of treatment remains open reduction and internal fixation. The purpose of the study is to observe the clinical effect of an anterior ankle C approach (ankle-C) combined with minimal invasive plate osteosystems (MIPO) for tibial pilon fractures (AO/OTA 43C, combined with fibula fractures). Methods A retrospective comparative analysis was performed on the clinical data of 33 patients with C-type pilon fractures (combined fibula fractures) admitted to our department from July 2018 to July 2021, including 12 cases treated with ankle-C (a-C) approach and 21 cases with conventional approach (including combined approach). All patients were followed up for over 6 months. Visual Analogue Scale (VAS), AOFAS Ankle-Hindfoot Scale (AOFAS-AHS), wound healing time, fracture healing time, and complications were used to evaluate the clinical efficacy. Results The scores of VAS and AOFAS in the a-C group scored better than the conventional group (P < 0.05), especially in the extent of limited range of motion (LROM) of ankle dorsiflexion-plantarflexion in 1 month after operation and at the last follow-up (P < 0.01). Bone healing was achieved in both groups 6 months after operation, with no implant exposure or infection. Among them, 4 cases in the conventional approach group had wound healing time exceeding 2 weeks. Conclusions For type C pilon fractures (combined with fibula fractures), ankle-C approach combined with MIPO technique has certain advantages in ankle function recovery and soft tissue repair, which provides an alternative for the treatment of type C pilon fractures.

Backgroud: A variety of extrapedicular puncture methods have been successfully used in percutaneous vertebroplasty (PVP) and percutaneous kyphoplasty (PKP). Currently, there are no reviews on extrapedicular puncture. Authors reviewed the puncture methods in different extrapedicular approaches and recommend appropriate extrapedicular puncture methods for thoracolumbar PVP (PKP). Methods: All the published research available in English and Chinese up to January 2020 from Web of Science, PubMed, Embase, China National Knowledge Internet (CNKI), and the Wanfang Database were included. The subject areas included "percutaneous vertebroplasty, percutaneous kyphoplasty, vertebral augmentation" and "extrapedicular, parapedicular, bilateral, and unilateral". Articles met the selection criteria if they contained the details of the puncture method of the extrapedicular approach. Results: We searched 118 studies, and after careful reading, 9 studies introduced 10 types of extrapedicular punctures in detail: the transcostovertebral approach, extrapedicular approach, unilateral extrapedicular approach, far-lateral extrapedicular approach, parapedicular access, lumbar extrapedicular approach, thoracic infrapedicular approach, extrapedicular modified inferior endplate access, extrapedicular approach along the predetermined individualized puncture route, and Kambin triangle approach. Conclusions: In thoracic vertebrae, the extrapedicular approach could be a better puncture method. In the upper lumbar vertebrae, the unilateral extrapedicular and far-lateral extrapedicular approach are recommended as the extrapedicular puncture methods. In L4-5, extrapedicular puncture is not recommended because of the high risk of injury to the lumbar artery.

Objective To investigate the role of aquaporin-3 (AQP-3) in hyperosmolarity-induced apoptosis of cultured rat nucleus pulposus (NP) cells. Methods Rat NP cells were cultured under different osmotic pressures (330 and 550 mOsm/kg), and the proliferation and apoptotic rate of the cells were determined using CCK-8 assay and flow cytometry, respectively. Western blotting and real-time quantitative PCR were used to detect the expression levels of apoptosis-related molecules (Bcl-2, Bax, cleaved caspase 3/caspase 3), and immunocytochemistry, Western blotting and real-time quantitative PCR were used to detect the expression of AQP-3 in the cells. The effect of lentivirus-mediated AQP-3 overexpression on apoptosis of NP cells was investigated after hyperosmolar exposure. Results An osmotic pressure of 550 mOsm/kg, as compared with 330 mOsm/kg, significantly decreased NP cell proliferation, increased the cell apoptotic rate, upregulated the expression of the pro-apoptotic molecules Bax and cleaved caspase 3/caspase 3 (P < 0.05), and down-regulated the expression of the anti-apoptotic molecule Bcl-2 (P < 0.05). The cells with lentivirus-mediated AQP-3 overexpression showed an obviously lowered apoptotic rate following the hyperosmolar exposure and significantly reduced expression of Bax and cleaved caspase 3/caspase 3 (P < 0.05) with an enhanced expression of Bcl-2 (P < 0.05). Conclusion Hyperosmolar exposure significantly promotes apoptosis of NP cells and reduce the expression of AQP-3. AQP-3 overexpression can partly attenuate apoptosis of NP cells following a hyperosmolar exposure.
