Objective:To observe the relationship of Hyaluronic Acid and transforming growth factor-?1 with different TCM syndromes of liver fibrosis. Methods:All rats of model groups were treated by CCl4 to establish the liver fibrosis model. Besides CCl4,the rats of liver-stagnation and spleen-deficiency group were treated by stimulating tails with forceps clip and gastric infusion of rhubarb decoction,and the rats of qi-deficiency and blood-stasis group were treated by the method of swimming-fatigue. Then every group was intervened by the relevant medicine. After all treatments,the HA and TGF-?1 in serum were examined. Results:The HA and TGF-?1 of model groups were significantly higher than those of the control group(P

OBJECTIVETo investigate the dynamic expression of TGF-beta1/Smad protein in rats with liver fibrosis induced by carbon tetrachloride (CCl4), to study mechanism of TGF-beta1/Smad signaling and the relationship between its transduction and liver fibrosis.

METHODSFifty healthy male SD rats were randomly divided into two groups: normal control group and model group. Experimental liver fibrosis was induced by subcutaneous injection of CCl4. After six weeks and nine weeks, histopathological changes and degrees of fibrosis were observed by optical microscopy. Meanwhile, the expression of TGF-beta1, TP3R-I, Smad2/3 and Smad7 proteins was detected by immunohistochemistry.

RESULTS(1) Pathological observation of hepatic specimens: hepatic tissue of model group rat had inflammation and fibrosis in different degrees. By comparing with the degrees of inflammation and fibrosis model groups were more severe than normal control group (P < 0.05). (2) Changes of protein levels about TGF-beta1/Smad: the expressions of TGF-beta1, TbetaR-I, Smad2/3 and Smad7 in rat hepatic tissue were detected with immunohistochemistry techniques. The expressions of the four items in model group were higher than those of normal control group (P < 0.01). In fibrosis model group, there exist considerable positive correlations among expressions of TGF-beta1, TbetaR-I, Smad2/3, Smad7 and degrees of fibrosis in livers (P < 0.05 or 0.01).

CONCLUSIONThere is close relation between the level of TGF-beta1, TbetaR-I, Smad2/3, Smad7 and the different liver fibrosis grades due to CCl4. The up regulation of TGF-beta1, TbetaR- I, Smad2/3 and Smad7 in liver tissue is involved in the progression of hepatic fibrosis.

AIM: To determine the relevance of NADPH oxidase subunit p22hox and the expression of superoxide anion on ventricular remodeling in myocardial infarction (MI) rats. METHODS: MI of Sprague-Dawley rats were established by left anterior descenting coronary artery ligation. 8 weeks after MI, Doppler echocardiography, hemodynamic study and histomorphometry were performed to analyze the ventricular remodeling. The level of thiobarbituric acid reactive substance in plasma and myocardium were measured, and the distribution of superoxide anion was observed with laser scanning confocal microscope. The expression of p22phox mRNA and protein level was detected by RT-PCR and immunohistochemistry. RESULTS: The left ventricular remodeling was significant in MI rats, also the level of thiobarbituric acid reactive substance increased in the plasma and non-infarcted myocardium. The expressions of p22-phox mRNA and protein levels, and superoxide anion increased in infarcted and non-infarcted myocardium in MI rats. CONCLUSION: Our results suggest that the expression of NADPH oxidase and its derived superoxide anion may take part in left ventricular remodeling through oxidative stresss after MI.

AIM: To clarify the protective effect of long-term administration of 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase inhibitor fluvastatin on ventricular remodeling after myocardial infarction (MI) in rats and its mechanisms. METHODS: Myocardial infarction were established by ligated left coronary anterior artery in SD rats, 24 hours after the operation, the survival rats were treated by gavage fluvastatin (20 mg?kg~(-1)?d~(-1)) or distilled water for 8 weeks. Doppler echocardiography, homodynamic and cardiac histomorphometry were used to assess the ventricular remodeling and cardiac function. The plasma levels of total cholesterol (Tch), creatinine (Cr), glutamic-oxal (o) acetic transaminase (AST), lipid peroxidation (LPO), glutathione perioxidase (GSH-PX), nitrogen monoxide (NO_2~-/NO_3~-) were detected. RESULTS: The Tch, Cr and AST were not significant difference in groups. Left ventricular end-diastole pressure, right relative weight, left ventricular posterior wall thickness, collagen volume fraction and the lung weight were decreased in AMI+fluvastatin group compared to AMI group (P

Minimal access spinal surgery(MASS),a new minimally invasive technique,has been developed on the basis of classic minimally invasive spinal surgery(MISS).With some special equipments,this procedure can reduce approach-related morbidity and collateral damage to surrounding tissues,and can be performed under direct visualization of the spine.The MASS combines the merits of MISS and traditional open procedures,and comparable results can be obtained while decreasing approach-related complications and learning curve.Now,the application of MASS has become more frequent in clinical practice due to its favourable characteristics in curative effect,postoperative recovery and economic efficacy.

After the structural reform in the food and drug supervision system, the knowledge structure and the professional re-quirements of the supervisors is unmatched, which hinder the fulfillment of regulatory responsibilities and the performance of adminis-trative efficacy. Effective ways for team building are actively explored throughout the country. The paper introduced the adult corre-spondence education of the supervisors in Zhejiang Ningbo food and drug supervision system to provide a good example for training work throughout the country and some useful suggestions for the quality improvement of the supervision team.

Abstract: Objective　To analyze the distribution and drug resistance evolution characteristics of pathogenic bacteria of bloodstream infection in nine tertiary hospitals in Yunnan Province from 2017 to 2021, so as to provide reliable basis for rational selection of antibiotics in clinic. Methods Using the drug sensitive paper method or instrument method, the bacteria identification and drug sensitivity test were carried out in nine tertiary hospitals in different regions according to the unified technical scheme. The results were judged according to the Clinical and Laboratory Standards Institute (CLSI) breakpoint standard in 2021, and use WHONET5.6 for data statistical analysis. Results A total of 12 003 strains of pathogenic bacteria were isolated from bloodstream infection samples in the past five years, including 7 442 strains of Gram-negative bacteria (62.0%) and 4562 strains of Gram-positive bacteria (38.0%), with an increasing trend in the number of isolated strains; of these, 163 strains (1.4%) were isolated from outpatients and 11 840 strains (98.6%) were isolated from inpatients. The top three gram-negative bacteria were Escherichia coli, Klebsiella pneumoniae and Acinetobacter baumannii, of which 309 strains (4.2%) were carbapenem-resistant Klebsiella pneumoniae (CR-KPN), 29 strains (0.4%) carbapenem-resistant Escherichia coli and 19 strains (0.3%) carbapenem-resistant Enterobacter cloacae, and the number of CR-KPN was on the rise year by year. The top three Gram-positive bacteria were coagulase-negative staphylococci, Staphylococcus aureus and Enterococcus faecium, of which methicillin-resistant Staphylococcus aureus (MRSA) was detected for 213 strains, accounting for 27.7%, and decreased from 40.0% in 2017 to 23.4% in 2021, showing a downward trend year by year. No vancomycin-resistant staphylococci and enterococci were found. Conclusions The detection and composition of bloodstream infection pathogenic bacteria in multicenter have not changed much in the past five years, but each hospital has its own characteristics. The number of carbapenem resistant Enterobacteriaceae increased year by year, which should be paid more attention.
