Objective To observe the changes of extracellular matrix(ECM) production and hypertrophy of glomerular mesangial cells(GMCs) induced by high glucose(HG),and the inhibitory role of myriocin(ISP-1).Methods GMC cultured with normal glucose(5.6 mmol/L D-Glucose,NG),HG(25.2 mmol/L D-Glucose) and HG plus ISP-1(100 mg/L) for different durations(0,24,48,(72 h)).The sizes of GMC were indicated by forward scatter intensity,measured by flow cytometery,and the levels of fibronection(FN),collagen Ⅳ(Col Ⅳ),laminin(LN),precollagen Ⅲ(Pcol Ⅲ) and hyaluronic acid(HA) in the supernatant of cultured GMC were detec-(ted) by ELISA.Results Compared with NG,HG could induce GMC hypertrophy(P

Objective To analyze the levels and speciation of arsenic metabolites in urine of rats treated with sodium arsenite and sodium arsenate in order to investigate the different aspects of metabolism between sodium arsenite and sodium arsenate,thus to understand further the basic data about relationship between it's metabolism and mechanism of toxicity. Methods Seventy Wistar rats,weighting 80-120 g,were divided into 7 groups of 10 each,such as normal control group,high,middle and low sodium arsenite group and high,middle and low sodium arsenate group. After the animals were fed for one month,the urine was collected by metabolic cage in 12 hours. Applying the high efficiency liquid chromatography and hydride genesis atomic fluorescence spectroscopy (HPLC-HGAFS),the levels and speciation of arsenic metabolites were determined in urine of rats. Meanwhile,the recovery rate of dimethyl arsinic acid(DMA) would be determined to estimate the degree of accuracy of results. Results The levels of iAs~(3+),iAs~(5+) and DMA in middle sodium arsenite group[(121.66±1.26),(10.26±2.68),(200.91±0.56) μg/L]were higher than the high sodium arsenite group[(113.20±0.75),(5.16±1.32),(147.70±μ0.77)μg/L,all P < 0.05]and low sodium arsenite group[(79.35±2.12),(5.13±2.25),(56.35±1.23)μg/L,all P < 0.05]. The levels of iAs~(3+) and DMA in middle sodium arsenate group[(315.81±1.69),(245.12±1.18)μg/L]were higher than the high sodium arsenate group[(85.03±0.56),(110.34±1.04)μg/L,all P< 0.05]and low sodium arsenate group[(22.97±2.67),(15.75±2.15)μg/L,all P < 0.05]. Compared with sodium arsenate group,the levels of iAs~(3+) and DMA in high and low sodium arsenite group were higher(all P < 0.05) ; and the levels of iAs~(3+) and DMA in middle sodium arsenite group were lower(all P < 0.05). Meanwhile,the average urinary recovery rate of DMA of rats in different sodium arsenite group were 94.80%-102.70%,and the average urinary recovery rate of DMA of rats in different sodium arsenate group were 95.33%-108.40%. Conclusion The speciation and levels of arsenic are influenced by the external exposure dose,and some distinction appeared in the metabolism and metabolic path between sodium arsenite and sodium arsenate in urine in vivo.

Health management plays an important role in the control of medical costs and in maintaining people' s health.Since the beginning of health management performance in our country,the major problems were:inadequacy of govement's support;imperfect laws;irregular marketing operation;lack of feasible health management model;controversy over long-term economic benefits;lack of awareness on health in common people and so on.To solve these problems,it is necessary to strengthen government support,and enhance people's health awareness,and explore the health management model consistent with the actual situation in China.

Objective To study prognosis of patients with fulminant hepatitis after plasma ex- change treatment using model for end-stage liver disease(MELD)scoring system.Methods 160 pa- tients were randomly divided into plasma exchange group and control group,and MELD score was calculated according to the original formula for each patient.The efficacy of plasma exchange was as- sessed by mortality and improvement in biochemical parameters and MELD score.Results The levels of total bilirubin(TBIL),INR and MELD score of patients whose MELD scores were between 30 and 40[TBIL,(379.4?40.4)?mol/L; INR,2.5?0.2; MELD,30.8?3.8]were lower than before PE treatment[TBIL,(509.7?64.6)?mol/L;INR,3.5?0.3;MELD,37.3?3.5].The levels of TBIL and INR and MELD score of patients whose MELD scores were higher than 40 [TBIL,(595.6?61.5)?mol/L;INR,3.8?0.4;MELD,39.8?3.5]were lower than before PE treatmem [TBIL, (650.4?66.3)?mol/L;INR,4.4?0.6;MELD,45.2?4.2].The mortality of patients in PE group with MELD score from 30 and 40 was 50.0%,while it was 86.7% in control group,showing significant differ- ence between PE group and control group(P＜0.01).The mortality of patients with MELD scores higher than 40 was 91.2% in PE group and 100% in control group,showing no significant difference between these two groups(P＞0.05).Conclusions Plasma exchange treatment can decrease the serum TBIL level, INR and MELD score of patients with fulminant hepatitis and improve liver function.Compared with the control group,plasma exchange can significantly decrease the mortality of patients in PE group with MELD score from 30 to 40,but no effect on patients with MELD score higher than 40.

Objective To evaluate the clinical efficacy of lamivudine in preventing liver injury induced by anti-tuberculosis drugs in hepatitis B virus(HBV)carriers.Methods One hundred and ten HBV carriers treated with anti-tuberculosis drugs were randomly divided into lamivudine group and control group.Patients in both groups were treated with conventional anti-tuberculosis drugs (isoniazid,rifampicin,pyrazinamide,streptomycin or ethambutol)for 6-8 months.However, patients in lamivudine group were treated with lamivudine 100 mg orally dairy concomitantly.Before and after treatment,the clinical manifestation,liver function and serum HBV DNA level of patients were evaluated.Statistical analysis was performed using t test and x~2 test.Results During 6-8 months of treatment,the incidence rate of liver injury was 9.1% in lamivudine group,while it was 38.2% in control group(P0.05).Conclusion Lamivudine is effective and safe in reducing liver injury induced by anti-tuberculosis drugs in HBV carriers.
