To analysis the differences between Tripterygium wilfordii and T. hypoglaucum, specimens of their leaves were collected from five production regions and analyzed by ultra performance liquid chromatography coupled with quadrupole time of flight mass spectrometry (UPLC-Q-TOF-MS). The data were analyzed by multivariate statistical method, such as hierarchical cluster analysis (HCA) principal component analysis (PCA) and orthogonal signal correction partial least square discrimination (OPLS-DA). Potential markers with VIP values above 5.0 and corresponding r values above 0.85, were selected and further tested by combining mann-Whitney nonparametric. Those with P < 0.001 and AUC = 1 were confirmed as metabolite markers to discriminate them from each other. Results revealed that the two species were obviously different in their leaf metabolites. Based on their mass spectra, 23 potential metabolite markers were identified to distinguish T. wilfordii from T. hypoglaucum.

OBJECTIVETo explore the prevalence of syphilis and risk factors on pregnant women in Fujian province.
METHODSFrom July 1st, 2004 to June 30th, 2006, epidemiologic methods as questionnaires to fill in and rapid plasma reagent testing (RPR) were performed. Pregnant women with positive RPR test and then were confirmed by treponema pallidum test (TP). Intervention was provided to the pregnant women who were followed up to the postpartum periods. Results were compared during the peri-neonatal stage between syphilis-infected and non-infected women. Factors which were relative to syphilis infection were analyzed by simple and then further logistic regression analysis.
RESULTSThere were 38 418 pregnant women under study, of whom 772 were confirmed including 60 who were still pregnant. The prevalence of syphilis during pregnancy was 1.85% (712/38 418), with mostly underlying syphilis which played an important role during the neonatal stage. Main risk factors to have been found as: women's occupation, cultural background, place of living, husband's occupation, family income, having sexually transmitted disease(STD) infection. The prognosis of peri-neonatal stage was worse if the mother was having blood RPR test positive. Mortality of peri-neonatal, preterm birth rate and low-birth weight rate were found also higher among mothers when RPR was positive (P < 0.01).
CONCLUSIONThe prevalence of syphilis in Fujian province was going up yearly. 8 factors including women's occupation, cultural background, place of living, received poor health education, having multiple sexual partners, husband's occupation, family income and having STD were main risk factors in the province, the mother's status of syphilis infection would strongly relate to the peri-neonatal stage of pregnancy.

OBJECTIVETo study the prevalence and principal rules of women with syphilis during pregnancy and to develop relative methods to prevent maternal-fetal transmission.
METHODSA nested case control study on epidemiologic research was used based on review and preview methods on prevention and cure. Targeting pregnant women with syphilis diagnosed during premarital or pregnancy stages and were identified through rapid plasma reagin test (RPR) but confirmed by treponema pallidum test (TP),a total number of 339 women receiving treatment, intervention and being followed throughout the pregnant and neonatal periods.
RESULTSThe prevalence of syphilis in pregnancy was 2.33%, and the positive rate in neonatal cord blood was closely associated with the opportunity of getting maternal treatment. The lowest RPR positive rate was among these women who got pregnant after receiving the treatment. The RPR positive rate of neonatal cord blood was positively relative to the mother's RPR titer. The higher was the mother's blood RPR titer, the worse the prenatal prognosis would turn to.
CONCLUSIONMother's blood RPR titer and the opportunity of getting treatment were strongly associated with the positive rate in neonatal cord blood. Pregnancy after receiving the treatment was a powerful measure to prevent the maternal-fetal transmission of syphilis.

To standardize the harvest ways of Dendrobium officinale and improve the quality and yield of D. officinale, a field experiment was carried out to study the effect of two kinds of harvest ways, which were keeping some of the axial shoot and harvesting all of the shoot by the end of the year. Then, the agronomic traits and yield were measured and the contents of polysaccharides and extractum were determined. The results showed that the harvest ways significantly affected the growth of D. officinale. Keeping some of the axial shoot could significantly improved the number of sprout, stem length, internode number and the internodal length, which also triggered increase the weight of fresh stems, leaves and the total of them and dry stems in per unit area, but it could not promote the stem diameter and the polysaccharide content in stems. Keeping some of the axial shoot moderately was conducive to the improvement of the production of medicinal materials in the process of harvesting by promoting the germination and growth of new buds, and to ensure the polysaccharide content by regulating the illumination and the density of cultivation.

To analyze the regularity in combined medication with Xiyanping injection (Xiyanping for short) in the real world by as- sociation rules. Totally 5 822 patients using Xiyanping injection was collected from the 18 Class III Grade I hospitals nationwide to study the combined medication information of the patient with lung infection and make the analysis by using association rules and Apriori. According to the results, major drugs combined with Xiyanping in treatment of lung infection included compound amino acid, inosine, coenzyme A, cytidine triphosphate, vitamin C. Common drugs combined with Xiyanping can be divided into 5 categories: nutrition support therapy (vitamin C, compound amino acid) , coenzymes (coenzyme A, cytidine triphosphate, inosine), expectorants and antiasthmatics (ambroxol, salbutamol, doxofylline), hormones (dexamethasone, budesonide), antibiotics (mainly cefminox). The main combined medicines mostly conformed to the regularity for drugs treating lung infection. In addition, there were two most common medical combination models: the model for Xiyanping combined a single medicine is Xiyanping + nutrition support therapy, while the model for Xiyanping combined two or more than two medicines is Xiyanping + nutrition support therapy + coenzyme. Pharmacologically, Xiyanping is mostly combined with western medicines with similar pharmacological effects to substitute or supplement the antibiotic effect in treating lung infection. However, further studies shall be conducted for the safety and rationality of the combined medication based on clinical practices, in order to provide reference for clinical medication.

The study is aimed to make the most of available space of Dendrobium officinale cultivation facility, reveal the yield and functional components variation of stereoscopic cultivated D. officinale, and improve quality, yield and efficiency. The agronomic traits and yield variation of stereoscopic cultivated D. officinale were studied by operating field experiment. The content of polysaccharide and extractum were determined by using phenol-sulfuric acid method and 2010 edition of "Chinese Pharmacopoeia" Appendix X A. The results showed that the land utilization of stereoscopic cultivated D. officinale increased 2.74 times, the stems, leaves and their total fresh or dry weight in unit area of stereoscopic cultivated D. officinale were all heavier than those of the ground cultivated ones. There was no significant difference in polysaccharide content between stereoscopic cultivation and ground cultivation. But the extractum content and total content of polysaccharide and extractum were significantly higher than those of the ground cultivated ones. In additional, the polysaccharide content and total content of polysaccharide and extractum from the top two levels of stereoscopic culture matrix were significantly higher than that of the ones from the other levels and ground cultivation. Steroscopic cultivation can effectively improves the utilization of space and yield, while the total content of polysaccharides and extractum were significantly higher than that of the ground cultivated ones. The significant difference in Dendrobium polysaccharides among the plants from different height of stereo- scopic culture matrix may be associated with light factor.
