Objective To observe the effects and the functions of valsartan and simvastatin in early diabetic nephropathy. Methods A total of 80 patients with early diabetic nephropahy were randomly divided into two groups.The patients in control group(n=40)received valsartan at a dose of 80rag/day ,while in treated group(n=40)on the base of the same treatment as control group, added simvastatin 20 mg/everyrfight. To compare the differences of lipids,urine albumin excretion rate(UAER) and C-reactive protein(CRP) before or after treatments through 12 weeks. Re-sults The UAER of two groups decreased obviously after therapy,especially the treated group(P<0.01) ;the lipids and CRP also decreased evidently in the treated group (P<0.05). Conclusion The lipids, UAER, CRP of patients in early diabetic nephropathy could be down-regulated,with combined medication of the simvastatin and valsartan, and the injury of renal alleviated.

Chinese meteria medica (CMM) chain is a long-span chain covering agriculture which mainly depends on the forces of nature as well as high-tech CMM industry, CMM expertise industry and fast developing CMM circulation industry. Imbalance among the development of these industries produces bottlenecks and hinders the operation of the entire production chain. After analyzing the structure of Chinese meteria medica industrial chain from the perspective of national economy industry, three industry classifications and differentiation of factor intensity, we conclude that the complex structure of CMM industry chain is attributable to these three aspects. And the complexity is mainly shown at complex industry, varied product types, different coordination of various industrial sections and different technical growth speed of varied industry. We propose that structural complexity is the natural property of the chain, which is the main reason of industry sector development imbalance and bottleneck. Results of this research could provide theoretical analysis for future research on the coordination of industrial chain and the efficiency of resource allocation.

Objective To study the predictive value of high-sensitivity C-reactive protein (hs-CRP) to perineonate mortality in early onset severe pre-eclampsia (EOSPE) pregnant women. Methods Seventy-five pregnant women with EOSPE (EOSPE group) and 75 pregnant women with gestational hypertension (control group) were selected. The serum tumor necrosis factor (TNF)-α, interleukin (IL)-2 and hs-CRP levels were detected. The data of perineonate death in EOSPE group were recorded, then the pregnant women were divided into death subgroup and survival subgroup. Results The hs-CRP, TNF-αand IL-2 levels in EOSPE group were significantly higher than those in control group:(7.2 ± 2.1) mg/L vs. (2.5 ± 1.0) mg/L, (28.9 ± 5.3) ng/L vs. (12.4 ± 3.5) ng/L and (134.3 ± 34.6) ng/L vs. (104.2 ± 28.5) ng/L, and there were statistical differences (P<0.05). In EOSPE group, 18 perineonates died (death subgroup), and 57 perineonates were survival (survival subgroup). The hs-CRP in death subgroup was significantly higher than that in survival subgroup: (8.9 ± 1.3) mg/L vs. (7.1 ± 1.2) mg/L, and there was statistical difference (P<0.05). But there were no statistical differences in TNF-αand IL-2 between death subgroup and survival subgroup (P>0.05). Receiver operating characteristic curve analysis result showed that the best threshold of hs-CRP for predicting the perineonate mortality caused by EOSPE was 7.98 mg/L, and the area under the curve was 0.779 (95％CI 0.637 to 0.922), with a sensitivity of 0.83 and a specificity of 0.68. Conclusions Inflammatory reaction is involved in the pathophysiological process of EOSPE, and hs-CRP is a good index to predict perineonate death in EOSPE pregnant women.

Objective To determine the prevalence of vulvovaginal candidiasis(VVC) in pregnant women,to test its antifungal susceptibility to miconazole,clotrimazole,fluconazole, itrocona- zole,and nystatin and to treat VVC with miconazole in pregnancy. Methods Vaginal swabs were collected from unselected pregnant women in prenatal clinic. The antifungal susceptibility of 131 strains of Candidas to miconazole,clotrimazole,fluconazole,itroconazole,and nystatin were detected by Neo-Sensitabs susceptibility testing. 66 cases of VVC were treated with 6 day-course of miconazole(400 mg/d). Results The prevalence of VVC in pregnant women was 12.7%(127/1000). 37.4%(374/1000) had previous VVC. 0.6%(6/1000)of women were recurrent VVC(RVVC),which occupied 4.7%(6/127) of VVC. C. albicans was the most frequently(87.1%) isolated pathogen followed by C. glabrata (9.9%) ,C. tropicalis(1.5%),and C. krsei(1.5%). The resistant rate of C. albicans to miconazole,clotrimazole,fluconazole,itroconazole,and nystatin was 10.5%、2.6%、 6.1%、 7.9%,and 0. All 13 strains of C. glabrata was susceptible to miconazole,nystatin and susceptible or susceptible-dependent-upon-dose (SDD) to clotrimazole,fluconazole,and itroconazole. The mycological cure rate of miconazole on day 7～14 and day 28～42 was 84.8%(56/66 cases) and 80.3% (53/66 cases). Conclusions VVC is very common in pregnancy. C. albicans is the predominant Candida species in VVC and has some resistance to miconazole,clotrimazole,fluconazole,itroconazole,and nystatin. Miconazole therapy is effective on VVC treatment in pregnant women. Non-effective treatment might be associated with Candidas resistance.
