Liver fibrosis occurs as compensatory responses to tis-sue repairing process in a wide range of chronic liver injures.It is characterized by excessive deposition of extracellular matrix (ECM)in liver tissues.The new discovery shows that suppres-sor of cytokine signaling (SOCS-3)is strictly associated with fi-brogenic progression of chronic liver diseases.Recent basic and clinical investigations also demonstrate that liver fibrogenesis is accompanied by SOCS-3,which critically determines the patho-
genesis and prognosis of liver fibrosis.This review summarizes current knowledge on SOCS-3 and the relationships between SOCS-3 and liver fibrosis.On the other hand,it also presents the different strategies that have been used in experimental mod-els to counteract excessive SOCS-3 and the role of SOCS-3 in the prevention and treatment of liver fibrosis.

Background Domestic waste classification is one of the major livelihood projects in China. With the introduction of the Shanghai Household Waste Management Regulation in 2019, the work of domestic waste classification has been carried out nationwide, yet its potential risks especially those derived from microorganisms are not clear. Objective To investigate the microbial characteristics of the domestic waste in typical residential areas in Shanghai, and provide a theoretical basis for health protection during the domestic waste classification process in Shanghai and throughout China. Methods Dry and wet waste from a typical residential community in Shanghai were collected during 2019–2020. Microbial colonies were counted in domestic waste and analyzed for growth patterns. Then through 16S rRNA sequencing using lllumina PE250, hierarchical clustering analysis was conducted to reveal the similarity and dissimilarity of community compositions in different domestic waste groups, alpha diversity was estimated to reflect the richness and diversity of bacterial communities, principal co-ordinates analysis of unweighted UniFrac distance was performed to estimate the beta diversity, and linear discriminant analysis effect size (LEfSe) was used to find features differentially represented among domestic waste groups. Results In the chosen typical residential community of this study, the numbers of microorganisms in waste were quite different, with lower numbers of microorganisms in dry waste than the numbers in wet waste. In addition, different growth curves of microorganisms were shown for different seasons, and the peak baterial colony numbers were 200 CFU·cm⁻², 6×10⁵ CFU·mL⁻¹, 10 CFU·cm⁻², and 2×10⁶ CFU·mL⁻¹ for summer dry waste, summer wet waste, winter dry waste, and winter wet waste, respectively. The results of 16S RNA demonstrated significant differences in α and β diversity indicators among different waste groups, and the difference in waste classifications was larger than the difference of the same classification of waste in different seasons. The main compositions of bacterial colonies in domestic waste was Proteobacteria, followed by Firmicute and Bacteroidota. The clustering analysis showed that the microbial composition in summer dry waste was close to that in winter dry waste, while other groups were quite different. In total 48 differential bacterial taxa were found at the level of genus including Pseudomonas and Pantoea. Conclusion Different seasons and different classifications of domestic waste present varied microbial characteristics, with different potential pathogenic microorganisms. Together with other related studies, we suggest that different measures should be taken for different domestic wastes to prevent and control the health hazards associated with waste classification.

Objective To compare the hemostatic safety and efficacy of a new butterfly femoral artery compression device (FACD) with those of manual compression (MC) in patients undergoing percutaneous peripheral endovascular interventions via femoral artery. Methods A total of 283 patients, who received percutaneous endovascular interventions via femoral artery during the period from September 2016 to December 2017, were enrolled in this study. After endovascular intervention, 167 patients received FACD to make hemostasis (FACD group), and 116 patients received MC hemostasis (MC group) . The patient's comfortableness, time used for hemostasis (min), limb immobilization time (h), and the incidence of vascular complications in both groups were analyzed. Results All 283 patients were included in analysis, the results indicated that the hemostatic success rates in FACD group and MC group were 96.4％ (161/167) and 94.0％ (109/116) respectively, the difference between the two groups was not statistically significant (P>0.05) . The postoperative Kolcaba Comfort Scale score of FACD group was (85.0 ±11.2) points, which was remarkably higher than (58.4±11.7) points of MC group (P<0.05), the time used for hemostasis in FACD group was (9.2 ±2.2) min, which was strikingly shorter than (18.5 ±2.9) min in MC group (P <0.05) . The limb immobilization time in FACD group was (10.4±2.4) hours, which was obviously shorter than (23.1±4.1) hours in MC group (P <0.05) . The incidence of vascular complications in FACD group was 3.6％, which was dramatically lower than 9.5％ in MC group (χ2=4.206, P=0.04) . Conclusion The use of the new butterfly FACD can promptly, safely and effectively stop bleeding of femoral artery puncture site. The new butterfly FACD is superior to MC in shortening hemostatic time and limb immobilization time, in reducing incidence of vascular complications, as well as in improving patient's comfortableness degree.

Objective:To observe the protective effects of Zhiganqing Prescription on the liver of C57BL/6J non-alcoholic fatty liver disease (NAFLD) mice induced by high fat diet and its effects on PI3K/Akt/FoxO1 signaling pathway, insulin resistance (IR) and gluconogenesis.Methods:A total of 48 8-week-old male C57BL/6J mice were divided into control group ( n=8) and modeling group ( n=40) according to random number table method. The control group was fed with ordinary diet, and the model group was fed with high-fat diet. The NAFLD model was established after 8 weeks of feeding. The modeling group was divided into model group, Pioglitazone group, Zhiganqing Prescription low-, medium-, and high-dosage group ( n=8 in each group) according to random number table method, and drug intervention lasted for 8 weeks. The body mass of mice was measured regularly during administration. Fasting blood glucose (FBG) levels were measured at 0 and 8 weeks of administration, and oral glucose tolerance tests (OGTT) were conducted. After the experiment, serum levels of GPT, GOT, TC, TG, LDL-C, HDL-C, FINS and C-P were detected and HOMA-IR was calculated. The pathological morphology of liver was observed by HE and PAS staining. The expression levels of PI3K and p-Akt were detected by IHC staining. The protein expression levels of PI3K, Akt, p-Akt, FoxO1, p-FoxO1, G6PC and PCK1 were detected by Western blot. Results:Compared with model group, the body weight of mice in each administration group decreased at 4, 6 and 8 weeks ( P<0.05 or P<0.01). At the 8th week of administration, the levels of FBG and OGTT AUC in each administration group decreased ( P<0.05 or P<0.01), the levels of GPT, TC, TG and LDL-C decreased ( P<0.01), and the GOT levels in Zhiganqing Prescription medium- and high-dosage groups decreased ( P<0.01). The HDL-C level in Zhiganqing Prescription medium-dosage group decreased ( P<0.05 or P<0.01), and the HOMA-IR level in Zhiganqing Prescription low- and medium-dosage groups decreased ( P<0.05 or P<0.01). The levels of FINS and C-P in each administration group increased ( P<0.05 or P<0.01), and the expressions of PI3K protein and p-Akt/Akt, p-FoxO1 /FoxO1 protein in liver tissues increased ( P<0.05 or P<0.01). The protein expressions of G6PC and PCK1 decreased ( P<0.05 or P<0.01). Conclusion:Zhiganqing Prescription can effectively control the body mass, blood glucose, liver function and blood lipids of NAFLD mice, improve IR and gluconeogenesis, the mechanism of which may be related to the activation of PI3K/Akt/FoxO1 signaling pathway.
