Objective:To evaluate rapid on-site evaluation (ROSE) in endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) for pancreatic solid lesions, and to compare the difference in ROSE performance between cytopathologists and trained endoscopists.Methods:A total of 168 consecutive patients with pancreatic solid lesions who underwent EUS-FNA from January 2014 to December 2020 at Fuding Hospital, Fujian University of Traditional Chinese Medicine were recruited. The patients who did not receive ROSE from January 2014 to November 2017 were included in N-ROSE group ( n=67). Since December 2017, the patients who intended to receive EUS-FNA were divided into E-ROSE group ( n=59, patients who received EUS-FNA and ROSE by endoscopists trained with cytopathology) and C-ROSE group ( n=42,patients who received EUS-FNA by untrained endoscopists and ROSE by cytopathologists) according to random number table. The number of punctures, sample adequacy, cytological diagnosis, final diagnosis and diagnostic efficiency (including the sensitivity, the specificity, the positive predictive value, the negative predictive value and the accuracy) in 3 groups were compared. Results:(1) The puncture number in N-ROSE group (4.22±0.76) was significantly more than E-ROSE group (3.12±0.79, P<0.001) and C-ROSE group (3.24±0.91, P<0.001). (2) The proportions of adequate samples in N-ROSE group [82.09% (55/67)] was significantly lower than those of E-ROSE group [96.61% (57/59), χ2=5.308, P=0.021] and C-ROSE group [97.62% (41/42), χ2=4.541, P=0.033]. The proportion of negative cytological diagnosis in N-ROSE group [40.30% (27/67)] was significantly higher than those of E-ROSE group [20.34% (12/59), χ2=5.848, P=0.016] and C-ROSE group [19.05% (8/42), χ2=5.348, P=0.021]. (3) The sensitivity of N-ROSE group [74.07% (40/54)] was significantly lower than those of E-ROSE group [94.00% (47/50), χ2=6.151, P=0.013] and C-ROSE group [94.44% (34/36), χ2=4.817, P=0.028]. The accuracy in N-ROSE group [79.10% (53/67)] was significantly lower than those of E-ROSE group [94.92% (56/59), χ2=5.433, P=0.020] and C-ROSE group [95.24% (40/42), χ2=4.155, P=0.042]. (4) There was no significant difference in any observational index between E-ROSE group and C-ROSE group ( P>0.05). Conclusion:ROSE in EUS-FNA can improve sample adequacy, the diagnostic sensitivity and accuracy, and reduce the number of punctures. The sample adequacy and diagnostic efficiency of endoscopists trained with cytopathology are comparable to those of cytopathologists.

慢性颈痛(chronic neck pain,CNP)是指由颈椎病[1]引起的症状持续>3个月的颈部疼痛,在影像学上通常表现为颈椎曲度变直和(或)椎小关节增生等退行性改变[2],临床上主要表现为头颈部活动受限、僵硬、上肢酸痛麻痹,手部无力以及肌肉收缩等,常伴发焦虑、抑郁、情绪低落等情绪障碍,不仅严重影响患者的生活质量,甚至还会给家庭和社会经济造成沉重的负担.根据国外流行病学调查显示[3],全球CNP的年龄标准化患病率是3551.1/10万.近年来,随着手机、电脑等电子设备的广泛普及,CNP发病率逐年升高,且发病年龄趋于年轻[4].有证据显示,>50%人可能从急性颈痛迁延为CNP,而高龄、女性、长期伏案工作及紧张焦虑等被认为是导致颈痛病程迁延的主要危险因素[5-6].因此,对CNP的临床诊断及合理干预具有重要性及急迫性.
The pathogenesis, clinical manifestations and pathological changes of diabetes nephropathy(DN) are related to the collateral disease theory of traditional Chinese medicine. In recent years, treatment and study of DN based on collateral diseases theory has gradually become a trend. Combined with literature, clinical experience and fundamental research, it is summarized that the core pathogenesis of DN is deficiency and stasis of collateral, the treatment method is to tonify deficiency for removing obstruction. It is believed that qi and blood should be taken as the key points in tonifying deficiency, and the difference between unblocking collaterals and removing blood stasis should be emphasized. The prescriptions should attach importance to strengthening healthy energy and Xinrun Tongluo herbs, and pay attention to slow attack and smooth collaterals. This paper expounds the pathogenesis and progress of DN from the theory of ‘collateral invasion in chronic sickness’, and discusses the current situation and thinking of treating DN from collaterals, with a view to providing reference for the prevention and treatment of DN.
Objective To investigate the diagnostic value of blue light imaging-bright (BLI-bright) and linked color imaging (LCI) for early esophageal cancer (EEC).Methods:Data of 63 consecutive patients with EEC who underwent gastroscopy under BLI-bright, LCI and white-light imaging (WLI) and endoscopic submucosal dissection (ESD) from May 2018 to August 2020 at Fuding Hospital Affiliated to Fujian University of Traditional Chinese Medicine were analyzed retrospectively in the cohort study. Subjective visibility analysis was performed by 6 endoscopists who were divided into 2 groups (expert group and trainee group) with 3 endoscopists in each group. The main observation index was the visibility score (ranking score, RS). The objective color difference (Δ E) between lesions of EEC and surrounding mucosa under 3 modes were analyzed by using the L *a *b * color space. Results:The overall RS of 6 endoscopists under WLI mode (2.57±0.81) was significantly lower than that under LCI (3.25±0.67) ( t=9.71, P<0.001) and BLI-bright (3.18±0.67) ( t=9.31, P<0.001). In the expert group, the RS of WLI (2.71±0.80) was significantly lower than that of LCI (3.33±0.66) ( t=7.16, P<0.001) and BLI-bright (3.42±0.62) ( t=8.09, P<0.001). In the trainee group, the RS of WLI (2.40±0.90) was also significantly lower than that of LCI (3.15±0.83) ( t=9.62, P<0.001) and BLI-bright (2.89±0.92) ( t=5.69, P<0.001), and the RS of LCI was higher than that of BLI-bright ( t=4.07, P<0.001). The Δ E between lesions of EEC and surrounding mucosa under WLI (11.52±3.40) was significantly lower than that under LCI (16.64±4.70) ( t=7.10, P<0.001) and BLI-bright (15.72±3.84) ( t=7.88, P<0.001). Conclusion:BLI-bright and LCI can effectively improve EEC visibility and color difference between EEC and surrounding mucosa. Furthermore, LCI is more conducive to the detection of EEC for the trainees.
对近年来糖尿病肾病从络病论治的临床研究及基础研究进行综述、分析和讨论,发现目前中医对糖尿病肾病的络病治疗以补虚通络法为主要原则,基础研究显示其作用机制主要与改善氧化应激和内质网应激、减轻炎症反应、改善微循环障碍和血管内皮损伤及减轻肾脏损伤有关.中医络病理论可为糖尿病肾病的临床和基础研究提供更多思路,也在临床运用中显示出一定优势.但目前补虚通络法的临床运用以补虚药物与化瘀药物的联合使用为主,而血瘀证与络病虽有重叠但并非同一范畴,因此当前糖尿病肾病的络病辨治未能结合络脉自身病变与主要致病因素及继发病机变化进行更有针对性的分期辨治,未能充分重视辛味药、藤类药及虫类药等经典络药的对证使用.此外,糖尿病肾病治络方药的基础研究缺乏与临床症状与实验室指标的关联分析.据此,倡导中医络病理论指导下更具体系的糖尿病肾病研究,进一步探索糖尿病肾病的络病实质,强调络药和微观辨证在糖尿病肾病靶药筛选过程中的重要性,探索糖尿病肾病中络药发挥作用的可能机制,以期为进一步推动络病理论和治络方药在糖尿病肾病的临床运用提供依据.

Purpose: This study was conducted to explore the diagnostic value of arterial spin labeling (ASL) combined with diffusion weighted imaging (DWI) in characterizing the spatiotemporal progression of infarct lesions in a rabbit middle cerebral artery occlusion (MCAO) model and predicting the acute cerebral infarction (ACI) volume. Materials and methods: Forty-two male rabbits (2.9 +/- 0.2 kg body weight) were used in this experimental study. Animals were initially anesthetized by intravenous injection of uratan. There were seven experimental groups with six rabbits in each group. The apparent diffusion coefficient (ADC) and cerebral blood flow (CBF) thresholds were established in the control group (n = 6), which were sacrificed at 12 h, stained for infarct volume, and imaged at each time point. Results: The normal ADC and CBF were estimated as 0.90 +/- 0.03 x 10(-3) mm(2)/s and 0.68 +/- 0.06 mL g(-1) min(-1), respectively. The viability thresholds of ADC and CBF yielding the lesion volumes (LVs) at 3 h, which best approximated the 2,3,5-triphenyltetrazolium chloride (TTC) infarct volumes at 12 h, were 0.52 +/- 0.02 x 10(-3) mm(2)/s (42.2 +/- 3% reduction) and 0.33 +/- 0.09 mL g(-1) min(-1) (51.0 +/- 11% reduction), respectively. The temporal evolution of the ADC- and CBF-defined LVs showed a significant perfusion/diffusion mismatch up to 1 h (p = 0.001). Conclusion: ADC values and ACI volumes were positively correlated, while CBF was negatively correlated, which is supposed to be a reference for predicting ACI volume.

哮喘发作有24小时缓冲期 一般来说,哮喘并不是一个突然性发作后直接导致死亡的疾病.而造成死亡的哮喘,多数由于合并其他疾病所致.在正常情况下,哮喘发作后大约半小时或以上,憋气、喘息或呼吸困难的症状会自主缓解. 哮喘发作时,气管会出现痉挛,但气管中的软骨也能帮助人体保持呼吸,吸入氧气.因此,对于单纯性的哮喘,若急性发作后,患者仍有24小时的缓冲时间,可前往医院寻求帮助.若哮喘发作且身边没有急救药物,应该在病情稍作缓解后,马上前往医院就诊治疗.
Objective:To evaluate the efficacy of linked color imaging (LCI) for the colorectal polyp detection, especially detection of adenoma.Methods:A retrospective analysis was conducted on the patients who underwent LCI or white light imaging(WLI) mode of LASEREO colonoscopy from May 2018 to March 2019.The differences of the detection rates in the global polyps, adenomatous polyps, flat polyps, small polyps (≤5 mm) and right-sided polyps under two modes were compared. Color differences between the adenomatous polyps and surrounding mucosa (ΔE) were examined under two modes, based on L *a *b * color space by the Commission Internationale de L′Eclairage in 1976.

Background Radix Astragali (Astragalus membranaceus var. mongholicus (Bunge)) and Coptis chinensis (Coptis chinensis var. angustiloba) are two commonly prescribed traditional Chinese herbs for diabetes. Astragalus Polysaccharide (AP) and Berberine (BBR) are active ingredients of these two herbs respectively and they are scientifically proved to have immunomodulatory and anti-inflammatory effects. They are also known for their antidiabetic potential by ameliorating insulin resistance (IR). AP and BBR have shown different advantages in treating diabetes according to previous reports. However, very few studies focus on the combined activities of the two potential antidiabetic ingredients. In this study, we discovered that reactive oxygen species (ROS) accumulated in IR-hepG2 cells and APBBR can decrease ROS level in model group significantly. We conjectured that APBBR can ameliorate IR in hepG2 cells by decreasing ROS level. In order to verify this hypothesis, we obtained phenotype and transcriptome information of IR-HepG2 cells and explore the underlying mechanism of the combination of AP and BBR(APBBR) activity on the relationship between ROS change in IR at whole-transcriptome level, so as to shed new light to efficacy and application of APBBR in treating diabetes. Methods The IR cell model was established with high-level insulin intervention. Glucose content, HepG2 cell viability as well as ROS level was detected to study the effect of IR-hepG2 cell phenotype. Unbiased genome-wide RNA sequencing was used to investigate alterations in experimental groups. Then, GO and KEGG functional enrichment was performed to explore the function and pathway of target genes. Venn analysis found out the differentially expressed lncRNAs that had close relationship with IR and ROS. Finally, we screened out candidate lncRNAs and these target genes to construct interaction network of differentiated lncRNA–miRNA–mRNA by according to the principle of competitive endogenous RNA (ceRNA). Results The biochemical experiments showed that APBBR administration could improve the proliferation activity of IR-HepG2 cells and decrease ROS level in model cells. The GO and KEGG functional enrichment analyses demonstrated several mRNAs remarkably enriched in biological processes and signaling pathways related to ROS production and IR progression. Interaction network suggest that APBBR ameliorates IR in HepG2 cells by regulating the expression of multiple genes and activating relevant signaling pathway to decrease ROS level. Thus, we demonstrated that APBBR ameliorated IR in hepG2 cells via the ROS-dependent pathway.
