Objective To observe the clinical efficacy of acupuncture at Jiaji (EX-B 2) in treating irritable bowel syndrome (IBS). Methods Sixty IBS patients were randomized into a treatment group and a control group, 30 in each group. The treatment group was intervened by electroacupuncture at Jiaji (EX-B 2), while the control group was by oral administration of Pinaverium Bromide tablets. The Bowel Symptom Scale (BSS) was adopted for observation before and after intervention, and the clinical efficacies were also compared. Results After intervention, the BSS scores were significantly changed in both groups (P<0.01). There was a significant difference in comparing BSS score between the two groups after intervention (P<0.01). The excellent rate was 86.7%in the treatment group versus 50.0% in the control group, and the difference was statistically significant (P<0.05). Conclusions Acupuncture at Jiaji (EX-B 2) is an effective approach in treating IBS.

OBJECTIVE:To observe the efficacy of mifepristone-releasing implants for endometriosis in rats.METHODS:Mifepristone-releasing implants(one tube at 0.75,1.5,and 3.0 cm in length,or 2,3,4 tubes at 3 cm in length) were embedded subcutaneously in model rats with endometriosis.The inhibition ratio on the endometriosis was measured 3 months later and compared with the placebo control group.RESULTS:In vitro mean drug release rate of about 9 ?g?d-1 was achieved for the one-tube implant at 3 cm in length for the first 15 days,but reduced to 5 ?g?d-1 after 30 days and which was maintained for over 6 months.Inhibition ratios of(18.6?17.3)%,(31.5?12.7)% and(72.2?12.3)% on the growth of endometrial explants were achieved after subcutaneous implantation of mifepristone-releasing implants(1 tube at 1.5 cm or 3 cm in length or 2 tubes at 3.0 cm in length),showing significance differences as compared with control group(P

Objective: To inquire into the testis gene change of mouse model with kidney-yang deficiency induced by overfatigue and excessive sexual life, the modern science mechanism of syndrome of kidney-yang deficiency and kidney controlling reproduction can be revealed on the gene level. Methods: The model of kidney-yang deficiency was established by each male mouse with six female mice keeping in the same cage, and all the male mice were forced to swim for 30-40 minutes everyday lasting for four weeks. The testis genes of mice in control group and model group were detected with Mouse OneArrayTM Whole Genome DNA microarray. The differentially expressed genes were screened under the condition of the relative fluorescence intensity ratio of the two groups ≥2 and ≤0.5 and further classified according to gene function by using Molecule Annotation System (MAS) created by CapitalBio Corp. Beijing, China. Results: The mouse model with kidney-yang deficiency was established successfully by the method of overfatigue and excessive sexual life. The scatter plot of gene expression profiles of comparing control group with model group was drawn. Differentially expressed genes were screened, including 2425 up-regulated genes and 3080 down-regulated genes. Among the first one hundred up-regulated genes, 41 genes were known and among the first one hundred down-regulated genes, 62 genes were known. These genes were mainly related to the cellular structure/function, material/energy metabolism, signal transduction/transmission, inflammation/immunization, cell apoptosis, transcription/translation,proliferation/differentiation and cell cycle. Conclusion: The testis gene of kidney-yang deficiency mouse had a wide change. The essence of kidney-yang deficiency syndrome and the theory of the kidney originating and controlling life reproduction were explained on the gene level.

Objective To evaluate the correlation and difference of reversed phase high performance liquid chromatography (RP-HPLC) and fluorescence polarization immunoassay (FPIA) on determining serum concentration of carbamazepine.Methods Fifty serum samples were collected,both RP-HPLC and FPIA methods were employed to determine the concentration of carbamazepine.The results were analyzed by paired t test,Bland-Altman and Deming regression methods,respectively.Results The results of measuring 50 samples by the two methods showed that FPIA datas were significantly higher than RP-HPLC datas,and there was statistically significant difference(P<0.05) and poorer consistency between two methods;There was good correlation between carbamazepine concentrations determined by the two methods.Deming regression equation was CFPIA=1.195 3 CRP-HPLC-0.144 0,and Pearson correlation coefficient was 0.968 5.Conclusion Clinicians should pay more attention to the difference of carbamazepine concentration determination by different methods when carbamazepine individualized dosage regimen was adjusted according to therapeutic drug monitoring.

Objective:To study the stability of compound Kushen mixed liquid to provide reliable evidence for safe clinical drug application.Methods:Compound Kushen injection was mixed respectively with 0.9% sodium chloride injection and 5% glucose injection,and then placed under the different conditions for 0,1,2,4,8,12,24 and 48 h.HPLC was conducted to determine the content changes of four components in compound Kushen mixed liquid,and the appearance,pH and insoluble particles were observed as well.Results:The mixed liquid of compound Kushen with 0.9% sodium chloride injection was stable in 48 h without the influence of light and temperature.However,the mixed liquid of compound Kushen with 5% glucose injection had poorer stability with storage time shorter than 12 h at room temperature and 2 h at high temperature.Conclusion:The stability of the mixed liquid of compound Kushen is closely related to the pH value of solvent.0.9% Sodium chloride injection is recommended as the solvent,and the mixed liquid should be used up in 48 h.

Objectives To understand the status of wild feces distribution and pollution in schistosomiasis endemic areas in Yunnan Province. Methods According to the distribution of Oncomelania hupensis snails and characteristics of human and ani-mal activities in recent five years 6 schistosomiasis endemic villages in Weishan Nanjian and Midu counties 2 villages each county were selected as the investigated areas and more than 4 hm2 area with snails around each village were investigated for the types and densities of wild feces. The schistosome infested feces was detected with the hatching method. Results Totally 63 hm2 were investigated and 420 wild feces were found in all kinds of environments. The densities of wild feces were 0.066 7 piles/100 m2 and the densities of wild feces of the road and the hillside were the highest 0.098 7 piles/100 m2 and 0.088 0 piles/100 m2 respectively .
