Shanghai Journal of Acupuncture and Moxibustion 2015;(12):1154-1156
ObjectiveTo compare the efficacies between conventional acupuncture plus acupoint application and conventional acupuncture plus TDP in treating dysmenorrhea due to blood stagnation led by cold.MethodSixty patients were randomized into two groups, 31 cases in the treatment group and 29 cases in the control group. The treatment group was intervened by conventional acupuncture plus acupoint application, while the control group was by conventional acupuncture plus TDP. Before and after the intervention, McGill Pain Questionnaire was adopted to compare the Pain Rating Index (PRI) score, Visual Analogue Scale (VAS) score, and Present Pain Index (PPI) score, and the therapeutic efficacy was also compared.ResultThe recovery rate was 58.1% in the treatment group, significantly higher than 24.1% in the control group (P<0.01); the total effective rate was 90.3% in the treatment group, significantly higher than 62.1% in the control group (P<0.01), indicating that the therapeutic efficacy of the treatment group was more significant than that of the control group. Before the intervention, there were no significant differences in comparing the PRI, VAS, and PPI scores between the two groups (P>0.05), suggesting the comparability. After the intervention, there were significant differences in comparing the PRI, VAS, and PPI scores between the two groups (P<0.05), and the PRI, VAS, and PPI scores were markedly decreased in the treatment group.ConclusionConventional acupuncture plus acupoint application can improve dysmenorrhea symptoms and reduce patient’s pain, and can produce a more significant efficacy compared with conventional acupuncture plus TDP.

Objectives Esophageal cancer development and progression is driven by the accumulation of genetic changes. In this study, we used tissue microarray to survey the expression of p53, p16 and COX-2 in esophageal cancer progression and their clinical implication. Methods We tested p53, p16 and COX-2 proteins by immunohistochemistry and tissue microarray in 86 specimens from different stages of esophageal cancer and 40 specimens from adjacent non-cancer tissue. Results The expression of p53 and COX-2 was significantly higher in tumor tissue than that in non-tumor ones. As for the expression of pl6, no significant difference was found between tumor and adjacent tissue. An obvious relation was observed among p53, p16 and COX-2 expression that esophageal carcinogenesis was highly correlated with the positive expression of p53 or COX-2, however, no reciprocal relationship to neoplastic progression was recognized with p53, p16 and COX-2. Conclusion We observed that the tissue with the positive expression of p53 or COX-2 was more likely to develop esophageal cancer. Further work will verify the hypothesis that the expression level of p53 and COX-2 in biopsy specimen is applicable to predict early outset of esophageal cancer.

The bioactivity of a working reference standard was determined by replicate bioassays with calibration against a primary reference standard. In this study the number of bioassay replicates needed for calibration first was calculated theoretically, and if the mean value of the experimental bioassay replicates fell within the predefined bioactivity level the bioactivity of the working reference was defined as 100%. Our results showed that when the total intermediate precision of the bioassay method was at 11.66% and the predefined bioactivity level was set at 95%-105% with a confidence level of 95%, 21 bioassay replicates should be carried out for calibration. The average value of the 22 experimental bioassay replicates was 101.96%, so the bioactivity of the working reference standard was consistent with that of the primary reference standard at 100%. The results suggest that a strategy of first calculating the number of bioassay replicates needed for calibration and then determining whether the resulting experimental mean value is within the predefined bioactivity level will be of value to the biopharmaceutical industry.

Objective To determine the risk factors of gallstones. Methods A case-control study was conducted on 4087 patients with gallstones (the study group) and 20435 individuals without gallstones (the control group) at the Health Center of Peking Union Medical College Hospital (PUMCH) between January 2007 to May 2010. Using age and sex, the study and the control groups were matched in 1 : 5 ratio. Data were statistically analyzed using Chi-square test and conditional logistic regression.Results Univariate analysis showed significant differences in diabetic mellitus (DM), systolic blood pressure (SBP), diastalic blood pressure (DBP), triglyceride (TG), high density lipoprotein cholesterol (HDL-CH) and body mass index (BMI) between the study and the control groups (P<0.05). Multivariate analysis confirmed that DM, SBP, HDL-CH and BMI were associated with gallstones, and their adjusted odds ratio (95% confidence interval) were 0. 825 (0. 736 ~0. 925), 0. 908 (0. 828~0. 996), 1. 211 (1. 056~1. 389) and 0. 746 (0. 691~0. 805), respectively.The incidences of total cholesterol (TCH) and low deasity dipoprotein cholesterol (LDL-CH) were not significantly different between the two groups (P>0.05). ConclusionsDM、SBP、HDL-CH and BMI were found to be the risk factors for gallstones. To prevent gallstones, weight reduction, blood pressure control and normalization of blood lipid are important measures.
