Biliary fibrosis (BF) is the result of pathological repair of bile tract injury, characterized by thickening and sclerosis of the bile duct wall and progressive stricture of the lumen, which may ultimately lead to serious adverse outcomes such as biliary obstruction, biliary cirrhosis, liver failure, and hepatobiliary malignancies. Current research describes BF as a pathological feature of certain bile tract diseases, lacking a systematic summary of its etiology, pathophysiology, molecular mechanisms, and treatment. BF is a common but easily neglected disease state in biliary system, which may promote the development and progression of hepatobiliary diseases through abnormal repair mechanism after pathological biliary tract injury. Based on the latest research progress from both domestic and international perspectives, the authors review the concept, clinical manifestation, etiology, pathogenesis, and therapeutic strategies of BF to provide a reference for clinical physicians.

Objective: To examine the long term outcome of splenic hilar lymphadenectomy (SHL) for locally advanced Siewert type Ⅱ and Ⅲ adenocarcinoma of esophagogastric junction (AEG) with a tumor diameter ≥4 cm. Methods: A total of 489 locally advanced Siewert type Ⅱ and Ⅲ AEG patients with a tumor diameter ≥4 cm who underwent radical resection from January 2010 to April 2016 were included. There were 383 males and 106 females. There were 225 patients aged≥65 years and 264 patients aged <65 years. SHL was conducted in 270 patients(SHL group). Wilcoxon rank-sum test or χ² test were conducted for inter-group comparison. Cox proportional hazard regression was used to analyze the long term outcome of SHL and the prognosis factors of overall survival. Kaplan-Meier curve was drawn finally. The results of survival analysis were verified by Log-rank test. Results: Followed-up to April 2021,the median follow-up time was 78.0 months (range: 74.0 to 85.0 months), the follow-up rate was 95.5%(467/489). The splenic hilar lymphnode metastasis rate of the SHL group was 12.6% (34/270). Younger patients (<65 years old), less complications, higher proportion of patients received adjuvant chemotherapy were demonstrated in the SHL group (χ²: 5.644 to 6.744, all P<0.05). Multivariate analysis showed that SHL was the independent prognosis factor of overall survival for patients with Siewert type Ⅱ and Ⅲ AEG and a tumor diameter≥4 cm (HR=0.68, 95%CI: 0.52 to 0.88, P=0.004) along with preoperative CA19-9, pathological T stage, pathological N stage, adjuvant chemotherapy and postoperative complication. Further subgroup analysis demonstrated that the SHL group had better 5-year overall survival than non-SHL group (62.4% vs. 39.2%, χ²=17.983, P=0.006) in Siewert type Ⅲ AEG rather than in Siewert type Ⅱ AEG(57.3% vs. 53.7%, χ²=3.031, P=0.805). Conclusion: In experienced center, splenic hilar lymphadenectomy can improve the prognosis of Siewert type Ⅲ AEG with a tumor diameter ≥4 cm.

Renal fibrosis is a common and irreversible pathological feature of end-stage renal disease caused by multiple etiologies. The role of inflammation in renal fibrosis tissue has been generally accepted. The latest view is that fatty acid metabolism disorder contributes to renal fibrosis. peroxisome proliferator activated receptor-gamma coactivator 1α (PGC1α) plays a key role in fatty acid metabolism, regulating fatty acid uptake and oxidized protein synthesis, preventing the accumulation of lipid in the cytoplasm, and maintaining a dynamic balanced state of intracellular lipid. In multiple animal models of renal fibrosis caused by acute or chronic kidney disease, or even age-related kidney disease, almost all of the kidney specimens show the down-regulation of PGC1α. Upregulation of PGC1α can reduce the degree of renal fibrosis in animal models, and PGC1α knockout animals exhibit severe renal fibrosis. Studies have demonstrated that AMP-activated protein kinase (AMPK), MAPK, Notch, tumor necrosis factor-like weak inducer of apoptosis (TWEAK), epidermal growth factor receptor (EGFR), non-coding RNA (ncRNAs), liver kinase B1 (LKB1), hairy and enhancer of split 1 (Hes1), and other pathways regulate the expression of PGC1α and affect fatty acid metabolism. But some of these pathways interact with each other, and the effect of the integrated pathway on renal fibrosis is not clear.

Development of rapid analytical methods and establishment of toxic component limitation standards are of great importance in quality control of traditional Chinese medicine. Herein, an on-line extraction electrospray ionization mass spectrometry (oEESI-MS) coupled with a novel whole process integral quantification strategy was developed and applied to direct determination of nine key aconitine-type alkaloids in 20 proprietary Chinese medicines (APCMs). Multi-type dosage forms (, tablets, capsules, pills, granules, and liquid preparation) of APCM could be determined directly with excellent versatility. The strategy has the characteristics of high throughput, good tolerance of matrix interference, small amount of sample (∼0.5 mg) and reagent (∼240 μL) consumption, and short analysis time for single sample (<15 min). The results were proved to be credible by high performance liquid chromatography-mass spectrometry (LC-MS) and electrospray ionization mass spectrometry, respectively. Moreover, the limitation standard for the toxic aconitines in 20 APCMs was established based on the holistic weight toxicity (HWT) evaluation and the severally, and turned out that HWT-based toxicity evaluation results were closer to the real clinical applications. Hence, a more accurate and reliable APCM toxicity limitation was established and expected to play an important guiding role in clinics. The current study extended the power of ambient MS as a method for the direct quantification of molecules in complex samples, which is commonly required in pharmaceutical analysis, food safety control, public security, and many other disciplines.

Objective To review the existing literature and quantitatively evaluate the association of circulating vaspin levels and the risk of gestational diabetes mellitus ( GDM) ． Methods We systematically searched the PubMed，EMBASE，Web of Science，China National Knowledge Infrastructure，and WanfangData databases up to June 2019． Pooled standardized mean differences ( SMDs) with 95% confidence intervals ( CIs) were calculated using random－ or fixed－effects models based on the heterogeneity of studies． Subgroup analyses，Meta－regression，sensitivity and publication bias were assessed to analyze the heterogeneity and the robustness of the results． All statistical analyses were performed using STATA 12．0． Ｒesults Nine articles ( 11 comparisons) published from 2013 to 2019 were included in our final Meta－analysis，covering a total of 738 patients with GDM and 661 normal pregnant women． There was significant difference in the overall maternal circulating vaspin levels between GDM patients and healthy pregnant women ( SMD= 0．613，95% CI: 0．044－1．182，P= 0．035) ． Subgroup analyses stratified by trimester in which vaspin was measured and whether BMI was matched suggested the similar trend to the overall result． Subgroup analysis according to ethnicity found that circulating vaspin level might not be related to GDM in " European" subgroup; sensitivity analysis by excluding moderate－quality studies and BMI－unmatched studies found that circulating vaspin levels were still related to GDM risk． Conclusions Our Meta－analysis indicated that maternal circulating vaspin levels might be positively correlated with the risk of GDM in Asians．
