The study aims to identify related substances in orlistat pharmaceutical substance from different production technologies. Advanced technologies including UPLC-QTOF-MS and UPLC-QTrap-MS were used and the structures or molecules of 10 kinds of related substances in orlistat were identified. The experimental data were valuable to the quality control and development of orlistat.

Objective To study the traditional Chinese medicine treatment in headache in menstruation of Ma Dazheng professor. [Methods]The paper expounds Professor Ma’s experience in treating headache in menstruation by analyzing the etiology, pathology, summaring the clinical thoughts and citing some typical cases. [Results]After the syndrome differentiation methods fitting which were from Ma Dazheng professor of TCM, good resulets have been achieved in the each model headache of dialectical classification. [Conclusion]The causes of headache have a lot, but according to the characteristics of the patients with the clinical syndrome differentiation, choosing precision wil get very good curative effect, it is a good guide for clinical treatment in a headach in menstruation.

Objective To understand the knowledge of sexual and reproductive health of undergraduates with different nationalities and provide scientific basis for sexual and reproductive health education in the nationalities university.Methods A self-developed questionnaire about sexual,reproductive health and sexual attitude was used to carry out investigation among 2 200 freshman.Results Formal education (family and school) do not become the main source of the sex knowledge; there were statistic significance of the comparison of sexual,reproductive knowledge and sexual attitude among minority undergraduates and Han nationality undergraduates,as well as among undergraduates from different minorities.Conclusions The undergraduates are thirsty for gaining general sexual knowledge from school and family during the period of university.It is necessary to improve sexual and reproductive knowledge through various ways for minority undergraduates.

Objective] To explore Ma Dazheng professor Chinese medicine treatment for the treatment of leukorrhagia. [Methods] Ma ’s treatment of gynecological disease discusses perspectives and clinical experience in terms of academic pathogenesis, treatment, therapies, their basic prescription compatibility and subtraction of the common CD features are summarized.[Results] Ma Dazheng professor applied lishi, tonifying spleen qi, kidney spleen, heat detoxification treatment, heat treatment and water as the main syndromes, pixu(spleen deficient), spleen kidney Yang deficiency type and the wet poison down, had clinical curative effect. [Conclusion] Ma Dazheng professor according to the characteristics of the patients in the process of treating leukorrhagia, syndrome differentiation and treatment, obtained the clinical accuracy and good curative effect, the gynecological clinical diagnosis and treatment had a good guiding significance, worthy of our in-depth study and understanding.

Alkaloids are a kind of natural nitrogen compounds which are widespread in the nature, with special and significant activities in pharmacology. In recent years, immunoassay techniques have been applied for the qualitative and quantitative analysis of alkaloids from traditional Chinese medicine (TCM). However, preparation and identifica-tion of artificial antigen with good immunogenicity are necessary and important for establishment of immunoassay for alkaloids from TCM. This paper summarized the designing ideas and procedures for preparation of artificial antigen and identification for the conjugates of alkaloids and carrier protein, in order to provide reference point for establish-ment and application of immunoassay techniques.

Toll-like receptors are an important pattern recognition receptors that recognize specific components of microbes and certain host molecules.Through initiated cell signaling pathway,they can induce immunocyte.Their activation triggers the innate immune response,and is crucial to the successful induction of Th1/Th2-phenotyped adaptive immunity.This review will give a brief overview of our current knowledge of TLRs as key components in immune responses and their regulation in respiratory tract diseases such as asthma.

The concentration of 5 nucleosides, uracil, uridine, guanidine, adenine and adenosine in culture of Paecilomyces hepialid was determined by the developed method of HPLC. The HPLC method was performed on a Waters SunFire C18 (4.6 mm x 250 mm, 5 μm) column with methanol-water gradient elution as the mobile phase. The detection wavelength was 260 nm and the colunmn temperature was controlled at 30 °C. The linear range was 10.00-200.00 mg · L(-1) (r = 0.9994) for uracil, 10.10-202.00 mg · L(-1) (r = 0.9992) for uridine, 10.00-200.00 mg · L(-1) (r = 0.9991) for guanidine, 10.30-206.00 mg · L(-1) (r = 0.9992) for adenine and 10.45-209.00 mg · L(-1) (r = 0.9991) for adenosine, respectively. The RSD of precision was 0.032%, 0.035%, 0.039%, 0.049%, 0.00080%, respectively. The average recoveries of uracil, guanidine, adenine, and adenosine were 97.34%, 99.10%, 101.6%, 98.61% and 100.2% with RSD of 1.3%, 2.1%, 0.96%, 0.95%, and 1.3% respectively. The method showed high sensitivity, good selectivity, linearity and repeatability, which was suitable for the content analysis of 5 nucleosides components in P. hepialid and its extracts.

Objective To investigate the change of plasma cholinesterases (CHEs) in the people with diabetes or fatty liver or overweight , and explore the role of CHE in these diseases .Methods The plasma CHEs in 2834 subjects were detected , and these subjects were divided into five groups , including diabetes , fatty liver , overweight , diabetes with fatty liver , and the normal groups . Results The plasma CHE activities in diabetes group , fatty liver group , overweight group , and diabetes with fatty liver group were all higher than the normal group [(8943 ±1896)U/L, (9716 ±1673)U/L, (8798 ±1710)U/L, (9385 ±1687)U/L vs (8028 ±1621) U/L], and the CHE level in the fatty liver group was highest among five groups .However, the CHE level in diabetes group or fatty liv-er group was not significantly different from that in the diabetes with fatty liver group .The CHE level of the people with components of metabolic syndrome (MS) was significantly higher than that without MS component [(8786 ±1514)U/L, (9141 ±1771)U/L, (9705 ±1628)U/L, (9138 ±1768)U/L, (9530 ±1607)U/L vs (7821 ±1324)U/L]),but the CHE level was not increased gradually with the increased MS component.The plasma CHE had a negative correlation with age ( P =0.00),but it had a positive correlation with triglyceride (TG), total cholesterol (TC), and body mass index (BMI)( P =0.00).Conclusions The plasma CHE activity was el-evated in diabetes group , fatty liver group , and overweight group , which might be a risk factor in these diseases .Controlling the plas-ma CHE might help to treat the metabolism diseases .

To investigate the clinical effect of tonifying the kidney and promoting blood circulation to promote oocyte decoction in the treatment of anovulatory infertility caused by polycystic ovary syndrome. Sixty cases were selected from the out-patient department of Xiyuan hospital of China academy of Chinese medical sciences and the Chinese academy of traditional Chinese medicine, Chinese medicine out-patient department. Sixty patients with PCOS patients were randomly divided into the treatment group and the control group, with 30 cases and 30 cases respectively. The treatment group was given decoction of the reinforcing kidney, activating blood circulation and ovarian stimulation compound recipe. The control group was treated with clomiphene. Through the treatment of 1-2 courses, in the treatment group the pregnancy rate was 56.67%, the ovulation rate 61%; in control group of clomiphene citrate ovulation ratepregnancy rate was 30% , 72.84% of ovulation rate. The difference was significant between two groups (P < 0.05), the pregnancy rate in the treatment group was higher than the control group. The treatment group has regulatory effect on FSH, LH and their ratio, and increase E2 level, decrease T, PRL, INS and other hormone levels, contributing to the mature development of the follicles and endometrium growth, increase the ovulation rate and pregnancy rate. The control group on FSH, E2 increased, LH, T, PRL and INS showed no obvious effect.
