Objective To investigate the effects of treatment of syphilis in pregnancy on perinatal prognosis. Methods Patients of syphilis in pregnancy from Hainan Provincial People′s Hospital and Haikou Municipal Maternal and Child Health Center during 1995.1 to 2001.1 were collected for retrospective analysis. Pregnant women with syphilis were divided into treated group and untreated group according to whether they received penicillin anti syphilis treatment or not during pregnancy. Results The total number of deliveries in the 2 hospitals during that period was 18 701, and 61 out of 9 805 women screened for syphilis were positive, giving an incidence of 6 2/1000. The perinatal mortality rates were 11 2% in treated group and 83 3% in untreated group, and incidences of congenital syphilis were 17 6% and 72 7% respectively. Conclusion Syphilis in pregnancy is a serious complication to harm the fetus. Screening of syphilis during pregnancy is necessary, and penicillin treatment is effective which may reduce the perinatal mortality rate and the birth of congenital syphilis baby.

Objective To assess the clinical efficacy of Shenmai injection for the treatment of anaphylactic shock patients and to observe the changes of microcirculation, blood pressure, and volume of urine. Methods Sixty cases of anaphylactic shock were treated with Shenmai injection plus Western medicine (treatment group) and 36 cases of anaphylactic shock treated with Western medicine only(control group). Hemorheological changes, consciousness, temperature, pulse and NSPO 2 were compared. Results The blood pressure recoverable rate of anaphylactic shock in the treatment group was significantly higher than that in the control group. The blood pressure recoverable rates at 4 h after the therapy were 68.3% and 22.2% in the treatment group and the control group, respectively. The average urine volume of treatment group at 2, 3, 4, 5 and 6 h after the therapy was significantly higher than that of the control group ( P

The experiment was carried out on cultured human stomach glandular carcinoma (SGC-7901 cell line). We previously reported the cytochemical changes of (Na~+-K~+)-ATPase activity and the changes of microvilli. We here studied the relationship among the cAMP, cAMP-PDEase, Mg~(++)-ATPase activity, the cell growth and differentiation. Cells were exposed to Immol/L cAMP together with 1 mmol/L theophylline. We showed cAMP specific fluorescence by immunocytochemical method, Mg~(++)-ATPase and cAMP-PDEase activity by cytochemical methods. We found that cAMP with theophylline not only inhibited the growth of these SGC-7901 cells as shown by our previous result, but also decreased the activity of Mg~(++)-ATPase and 3', 5'-cyclic monophosphate phosphodiesterase. The result indicates that exogenous cAMP can inhibit 3', 5'-cAMP-PDEase and Mg~(++)-ATPase activity and increase cAMP level in cell, and cAMP regulated the growth and differentiation of SGC-7901 cell line

OBJECTIVE:To evaluate the rationality of vancomysin use in the hospital where the authors work.METH-ODS:50patients taking vancomysin between May.2005and Nov.2005were studied.The pathogenic examination,monitoring of drug concentration in blood,indices of renal function,combined use of drugs as well as adverse effects in these patients were reviewed and analyzed statistically.RESULTS:On the whole vancomysin use in our hospital was safe.CONCLUSION:Vancomysin use will be made safer by monitoring drug concentration in blood,individualizing drug administration,and timely correcting the aggravating factors of kidney injury.

Objective To explore the expressions of autophagy-related gene Beclin-1 and LC3 in adriamycin induced eardiomyopathy rats,to prnve that autophagy might take part in the development of adriamycin induced eardiomyopathy in rats,so as to provide experimental and theoretical evidence for preventing and treating adriamycin induced cardiomyopathy.Methods Forty-five male SD rats were randomly divided into 3 groups,control groups,ADR group and ADR+3-MA group.The model of adriamycin induced cardiomyopathy rats was established.The tissue sample taken from the left ventricle wall was checked for the morphons of autophagosome by electron microscope. The expressions of Beelin-1 and LC3 of myocardium were detected.Results The morphons of autophagosome in ADR group was significantly increased compared with that in control and ADR +3-MA groups. The expression of Beclin-1 in myocardium of ADR group was significantly inereased compared with that in control and ADR +3-MA groups (P < 0.05).The level of LC3 in myocardium of ADR group was significantly increased compared with that in control and ADR+3-MA groups (P < 0.05).Conclusions Autophagy plays an important role in adriamycin induced cardiomyopathy.

On the basis of web databases, 111 compounds with nephrotoxicity and 90 compounds without nephrotoxicity were collected as data set of nephrotoxicity discrimination model, 39 compounds with tubular necrosis and 39 compounds without tubular necrosis were collected as data set of tubular necrosis discrimination model. The 6 122 molecular descriptors, including physicochemical, charge distribution and geometrical descriptors were calculated to characterize the molecular structure of the above-mentioned compounds. CfsSubsetEval valuation method and BestFirst-D1-N5 searching method were used to select molecular descriptors. Two models with high accuracy were built based on the support vector machine (SVM) approach, respectively. Accuracy, sensitivity, specificity and matthew's correlation coefficient of the two models were all above 70%. By using 22 nephrotoxicity compounds of Chinese medicine, the nephrotoxicity discrimination model was further verified with an accuracy of 72.73%. Using the tubular necrosis discrimination model, 10 potential compounds which can cause tubular necrosis were screened from the positive results of nephrotoxicity discrimination model, 6 of them have been verified by literatures. The results demonstrated that the discrimination models can be applied to screen nephrotoxic compounds from Chinese medicinal materials, and they also offer a new research idea for the further studies on the mechanism of nephrotoxicity.

In this study, based on web database, 324 neurotoxic compounds and 234 non-neurotoxic compounds were selected as a data set for neurotoxicity discriminative model. 6 122 molecular descriptors, including charge distribution, physicochemical and geometrical descriptors,were calculated to characterize the molecular structure of neurotoxic compounds. The combination of Cfs Subset Evaluation and Best First-D1-N5 searching was used to select molecular descriptors. A discrimination model with high accuracy was built based on the support vector machine (SVM) approach. Meanwhile, the model accuracy, sensitivity and specificity were all above 80%. Besides, 30 traditional Chinese medicine compositions with neurotoxicity were set as external validation to further verify the model accuracy,with anaccuracy of 73.333%. Using the model, 13 potential neurotoxic compounds were screened from Sophorae subprostrate Radix,4 of them were verified by literatures. The results demonstrated that the discrimination model can be applied to screen neurotoxic compounds from Chinese medicinal materials.

Nicotinic acid could increase high density lipoprotein and reduce serum total cholesterol, low density lipoprotein cholesterol and triglycerides in human bodies, thus is frequently applied in treating low high-density lipoprotein cholesterol and hypertriglyceridemia in clinic. However, according to the findings, nicotinic acid could also cause adverse effects, such as skin flush, beside its curative effects. In this study, bioisosterism, fragment-based search and Lipinski's Rule of Five were used to preliminarily screen out potential TCM ingredients that may have similar pharmacological effects with nicotinic acid from Traditional Chinese medicine database (TCMD). Afterwards, homology modeling and flexible docking were used to further screen out potential nicotinic acid receptor agonists. As a result, eleven candidate compounds were derived from eight commonly used traditional Chinese medicines. Specifically, all of the candidate compounds' interaction with nicotinic acid receptor was similar to nicotinic acid, and their docking scores were all higher than that of nicotinic acid, but their druggability remained to be further studied. Some of the eight source traditional Chinese medicines were used to lower lipid according to literature studies, implying that they may show effect through above means. In summary, this study provides basis and reference for extracting new nicotinic acid receptor agonists from traditional Chinese medicines and improving the medication status of hyperlipidemia.
