OBJECTIVE:To observe the efficacy and safety of Clotrimazole vaginal tablet in the treatment of pregnancy with vulvovaginal candidiasis. METHODS:106 pregnant patients with vulvovaginal candidiasis were randomly divided into observation group (56 cases) and control group (50 cases). Observation group was given one tablet Clotrimazole vaginal tablet,washed the genital area before treatment to keep clean and one Clotrimazole vaginal tablet was sent to intravaginal 5-6 cm,once every 2 day. Control group was given Lactobacillus vaginal capsule,once a day,washed the genital area before treatment and one Lactobacillus vaginal capsule was sent to intravaginal 5-6 cm. The treatment course for both groups was 8 d. No sexual activities during treatment and no other drugs. Clinical efficacy,clearance rate of candidiasis,pregnancy and incidence of adverse reactions in 2 groups were observed. RESULTS:The total effective rate and clearance rate of candidiasis in observation group were significantly higher than control group,carrier rate was significantly lower than control group,the differences were statistically significant (P<0.05). And there were no significant differences in the pregnancy and incidence of adverse reactions between 2 groups (P>0.05). CONCLU-SIONS:Clotrimazole vaginal tablet shows significant efficacy in the treatment of pregnancy with vulvovaginal candidiasis and can clear candidiasis,with good safety.

Objective To explore the subjective global assessment (SGA) to evaluate the nutritional status of patients with chronic obstructive pulmonary disease(COPD). Methods Patients with stable COPD (n=122) were included and divid?ed into three groups base on their SGA scores:SGA-A (n=21), SGA-B (n=57), SGA-C (n=44). Nutritional status of all pa?tients was assessed by SGA. Anthropometric measurement, biochemical test, pulmonary function test, COPD assessment test (CAT) and shuttle walking test (SWT) were studied between all three groups to search statistical significance and correlation with SGA. Results Body mass index(BMI), arm muscle circumference (AMC) and forced expiratory volume in the first sec?ond%of predicted (FEV1%Pred) were all lower in SGA-B and SGA-C than those in SGA-A(P<0.05),there were no statis?tical differences of these parameters between SGA-B and SGA-C. Triceps skin fold (TSF) was lower in SGA-C than that in SGA-B than that in SGA-A, while CAT score is the reverse order (P<0.05). The walking distance of incremental shuttle walking test (ISWI) and the endurance time of endurance shuttle walking test (ESWI) were lower in SGA-C than that in SGA-A (P<0.05). There were no statistical differences of forced expiratory volume in the first second (FEV1)/forced vital ca?pacity(FVC), biochemical parameters between all three groups. SGA scores correlated positively with CAT and negatively with anthropometric parameters, FEV1%Pred and SWT (P<0.05). However no correlations was deduced between SGA scores with FEV1/FVC and biochemical parameters. Conclusion SGA scores correlated with anthropometric parameters, FEV1%Pred, CAT and SWT. SGA is an effective method to assess the nutritional status in patients with stable COPD.

Aim To observe the protective effects and explore the possible mechanism of lycopene on hepatic injury induced by the combining use of isoniazid(INH) and rifampicin(RFP) in rats.Methods Chronic hepatic injury model was induced by INH and RFP.Low dosage,middle dosage and high dosage of lycopene(10,20,30 mg?kg-1 body weight) were given to protect liver injury.The serum level of AST and ALT,liver index,contents of malondialdehyde(MDA),glutathion(GSH) and superoxide dismutase(SOD) in liver were measured.Hepatic pathological changes were also observed after giving lycopene.Results Lycopene could reduce the liver index,the serum level of AST and ALT and the content of MDA,raise the liver GSH content and promote the activities of SOD in liver tissue in rats.Degeneration and necrosis of liver tissues were relieved.Conclusion Lycopene has protective effects on the hepatotoxicity in rats induced by the combination of INH and RFP for a long time,and the mechanisms is related to of antioxidation action of lycopene possibly.

Objective To study the influence and mechanism of seawater immersion on endothelial cell injury sustained by burn firearm combined injury to improve the early therapeutic efficacy. Methods The dogs with burn firearm combined injury were randomly divided into two groups: immersion group and control group. In immersion group, the dogs were immersed in seawater for 4 hours, then taken out from seawater. Blood samples were collected from central vein at 4 h, 7 h, 10 h, 20 h and 28 h following wound for the detection of changes of the circulating endothelial cells (CEC) and von Willebrand Factor (vWF). The same procedures except immersion were performed in the control group. Results The levels of CEC and vWF elevated at 4 h and 7 h following wound in control group( P

Objective To study the influence of seawater immersion on hemostatic function after burn in dogs. Methods Twenty healthy adult mongrel dogs of beth sexes weighing 12-15 kg were randomly divided into two groups: immersion group(n=10) and control group(n=10). The animals were anesthestized with 3% pentobarbital 30 mg?kg~(-1) i.v., intubated and mechanically ventilated. 5F Swan-Ganz catheter was placed via right internal jugular vein. 10% of the skin on the back was burnt(second degree). In immersion group the animals were immersed in seawater containing salt 25.3 g?L~(-1)(pH8.1, T21-23℃) with head and neck kept above water for 4h. In control group the animals suffered second degree burn of same area without being immersed in seawater. Blood samples were taken from Swan-Ganz catheter before burn(baseline)and 4,7,10,20,28 h after burn for determination of(1) circulating endothelial cell(CEC) count, (2)tissue-type plasminogen activator(t-PA), (3) plasminogen activator inhibitor(PAI) and (4) thromboxane B_2/6-keto-prostaglandin F_(1?)(TXB_2/6-k-PGF_(1?)). At the end of the experiment lung tissue was obtained for microscopic examination. Results The blood CEC count, PAI-1 level and TXB_2/6-k-PGF_(1?) ratio significantly increased while t-PA level significantly decreased at 4 h after burn in control group but at 4-28 h after burn in immersion group. The differences between the two groups were significant. Microscopic examination of the lung showed some thrombi in immersion group. Conclusion Burn causes acute damage to the endothelial cells of the whole body and disorder of hemostasis. They are more severe and last longer after seawater immersion.
