OBJECTIVETo observe the effect of external application of Zhuangshenling Recipe (ZR) combined with Western medicine (WM) on the heart function of chronic heart failure (CHF) patients of Xin-Shen yang deficiency, interior retention of water-fluid syndrome (XSYDIRWFS).

METHODSTotally 140 CHF patients of XSYDIRWFS were randomly assigned to two groups, the treatment group and the control group, 70 in each group. All patients received WM therapy. Those in the treatment group were applied with ZR at Xinshu (BL15) and Shenshu (BL23), while those in the control group were applied with placebos at Xinshu (BL15) and Shenshu (BL23). The therapeutic course for all was 12 weeks. The integrals of TCM syndrome, grading of cardiac function, brain natriuretic polypeptide (BNP), and 6 min walking distance were observed before and after treatment.

RESULTSAfter twelve weeks of treatment, the effective rate of improved grading of cardiac function, the total effective rate of TCM syndrome efficacy, and the BNP level were obviously better in the treatment group (P < 0.05). There was no statistical difference in 6 min walking distance between the two groups (P > 0.05).

CONCLUSIONExternal application of ZR combined with WM could improve the heart function of CHF patients of XSYDIRWFS.

Objective:To provide the basic data for the further revision of mycoplasma test method described in Chinese Pharma-copoeia and some references for the operation standardization of drug mycoplasma test. Methods:Two incubation conditions,namely aerobic conditions and microaerophilic conditions,were compared with respect to the growth status of mycoplasma in liquid and solid media. Results:The growth of mycoplasma was obvious difference between the two incubation conditions,and the microaerophilic con-ditions were better than the aerobic conditions. Conclusion:The microaerophilic conditions can be used in the incubation of mycoplas-ma test,which should be defined and standardized in the future Chinese Pharmacopoeia.

Microbiological data deviations ( MDD) investigation differs from out of the standard ( OOS) investigation in chemical inspection items. Investigating Out-of-Specification( OOS) Test Results for Pharmaceutical Production issued by FDA specifically ex-cludes microbiological and other biological assays. Until recently, there is not a definitive guideline for MDD investigation in the world. Some institutions and experts have explored the practice and theory of MDD investigation. Referred to the existing practical experience and theoretical achievement and based on the provisions of Chinese GMP (2010 revision) and the requirements of Chinese Pharmaco-poeia Ⅱ(2010 edition) Appendix XIX Q, the article discussed the methods for MDD laboratory investigation.

Objective:To investigate the growth-promoting properties and applicability of the mycoplasma test culture media pre-scribed in Chinese pharmacopoeia, and provide reference for the standardization of the drug mycoplasma test method. Methods: Re-spectively using four quantitative detection methods including sensitivity, degree of color change, colony counts and colony diameter, and mycoplasma media widely used in the world as the reference media, the growth-promoting properties of 4 batches of mycoplasma broth and 4 batches of arginine mycoplasma broth from four domestic manufacturers were investigated. Results:The results of sensitivity assay and absorbance detection showed that all the media inoculated with below 100 CFU test microorganisms exhibited visible color change. Furthermore, the results of color change degree and colony diameter showed that there were significant differences among the media products from different manufacturers(P<0. 01). Conclusion:Mycoplasma broth and arginine mycoplasma broth both can sup-port the growth of below 100 CFU test microorganisms. Due to the difference in the growth-promoting properties among the media prod-ucts from different manufacturers, the drug mycoplasma test workers should use more sensitive methods to examine the applicability of the media.

The present study aimed to investigate the clinical value of serum anti-mullerian hormone (AMH) and inhibin B (INHB) in predicting the ovarian response of patients with polyeystic ovary syndrome (PCOS).A total of 120 PCOS patients were enrolled and divided into three groups in terms of the ovarian response:a low-response group (n=36),a normal-response group (n=44),and a high-response group (n=40).The serum AMH and INHB levels were measured by enzyme-linked immunosorbent assay (ELISA).The follicle stimulating hormone （FSH),luteinizing hormone (LH),and estradiol (E2) levels were determined by chemiluminescence microparticle immunoassay.The correlation of the serum AMH and INHB levels with other indicators was analyzed.A receiver operating characteristic (ROC) curve was established to analyze the prediction of ovarian response by AMH and INHB.The results showed that there were significant differences in age,body mass index (BMI),FSH,total gonadotropin-releasing hormone (GnRH),LH,E2,and antral follicle counts (AFCs) between the groups (P＜0.05).The serum AMH and INHB levels were increased significantly with the ovarian response of PCOS patients increasing (P＜0.05).The serum AMH and INHB levels were negatively correlated with the age,BMI,FSH level,Gn,and E2 levels (P＜0.05).They were positively correlated with the LH levels and AFCs (P＜0.05).ROC curve analysis of serum AMH and INHB in prediction of a low ovarian response showed that the area under the ROC curve (AUC) value of the serum AMH level was 0.817,with a cut-off value of 1.29 ng/mL.The sensitivity and specificity were 71.2％ and 79.6％,respectively.The AUC value of serum INHB was 0.674,with a cut-off value of 38.65 ng/mL,and the sensitivity and specificity were 50.7％ and 74.5％,respectively.ROC curve analysis showed when the serum AMH and INHB levels were used to predict a high ovarian response,the AUC value of the serum AMH level was 0.742,with a cut-off value of 2.84 ng/mL,and the sensitivity and specificity were 72.7％ and 65.9％,respectively;the AUC value of the serum INHB level was 0.551 with a cut-off of 45.76 ng/mL,and the sensitivity and specificity were 76.3％ and 40.2％,respectively.It was suggested the serum AMH and INHB levels have high clinical value in predicting the ovarian response of PCOS patients.

Background Currently,the recommendation when treating acute biliary or pancreatic disease during pregnancy is to perform endoscopic retrograde cholangiopancreatography (ERCP) without radiation exposure,either empirically (with no radiographic guidance) or with ultrasound guidance.However,few published studies compared these two ways.This study aimed to compare ultrasound-guided ERCP with the procedure without radiographic guidance in the treatment of acute pancreaticobiliary disease in pregnant patients.Methods The clinical data of 68 pregnant patients with acute pancreaticobiliary disease admitted to our hospital between January 2004 and May 2010 were reviewed retrospectively.ERCP was performed without radiographic guidance in 36 cases (group A) and with ultrasound guidance in 32 cases (group B).Data on the following variables were compared between the two groups:surgical success rate,rate of complete stone removal,time to resolution of clinical manifestations and laboratory indicators,length of hospital stay,complications,outcome and differences in efficacy of ERCP during different stages of pregnancy.Results In group A,the rates of surgical success and complete removal of stones were 69％ and 60％,respectively; the corresponding values were 91％ and 89％ in group B (P ＜0.05).Postoperatively,clinical manifestations improved rapidly in all patients; there was no statistically significant difference between the groups (P ＞0.05).Leukocyte counts and liver function had improved significantly after one week in all patients; they recovered more quickly in group B ((8.64±1.83)days vs.(14.57±3.74) days,(14.29±4.64) days vs.(20.00±5.40) days,P ＜0.01).The hospital stay was shorter in group B ((16.28±7.25) days vs.(28.00±6.83) days,P＜0.001).The complication rate was 14％ in group A and 3％ in group B (P ＜0.05).There were no significant differences between the two groups in the procedure's efficacy during different stages of pregnancy.Conclusions In the treatment of acute pancreaticobiliary disease during pregnancy,ultrasound-guided ERCP is safer and more effective than performing the procedure empirically without radiographic guidance when performed by experienced practitioners.Its more widespread use is recommended.

Mutation (substitution, deletion, insertion, etc.) in nucleotide acid causes the maximal sequence lengths of exact match (MALE) between paralogous members from a duplicate event to become shorter during evolution. In this work, MALE changes between members of 26 gene families from four representative species (Arabidopsis thaliana, Oryza sativa, Mus musculus and Homo sapiens) were investigated. Comparative study of paralogous' MALE and amino acid substitution rate (d(A)<0.5) indicated that a close relationship existed between them. The results suggested that MALE could be a sound evolutionary scale for the divergent time for paralogous genes during their early evolution. A reference table between MALE and divergent time for the four species was set up, which would be useful widely, for large-scale genome alignment and comparison. As an example, detection of large-scale duplication events of rice genome based on the table was illustrated.
