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 explore risk factors for type 2 diabetes mellitus complicated with gallstone disease. Methods The clinical data of 429 type 2 diabetes mellitus patients complicated with gallstone disease (case group) and 2145 type 2 diabetes mellitus patients without gallstone disease (control group) were collected from the Health Center of Peking Union Medical College Hospital from January 2007 to May 2010. According to sure (SBP), diastolic blood pressnre (DBP), fasting blood glucose (FBG), total cholesterol (TC), Triglyceride (TG), high-density lipoprotein cholesterol (HDL-CH), low-density lipoprotein cholesterol (LDL-CH) and body mass index (BMI) were statistically analyzed by fourfold table chi-square test or conditional Logistic regression.Results Univariate analysis showed that there was a significant difference in the levels of SBP, FBG, TC, HDL-CH and BMI between the case group and the control group (x2 =20.323, 4.365, 4.028, 7.049, 7.319, P＜0.05). Multivariate analysis confirmed that SBP, TC, HDL-CH and BMI were risk factors for gallstone disease in patients with type 2 diabetes mellitus (x2 = 18. 047, 6. 905, 12. 884, 7. 557, P ＜ 0. 05). Conclusion Increased SBP, TC and BMI and decreased HDL-CH may be the risk factors for type 2 diabetes mellitus complicated with gallstone disease.

Background and purpose: High expression of telomerase and telomere stability are two common features in tumor cell. hTERT is a catalytic subunit of telomerase, TRF2 is extremely important to maintain the length and stability of telomerase. This study was to construct the recombinant adenovirus mediated shRNA to hTERT and TRF2, and to investigate the inhibitory effects of the vector by solo-inhibiting and connect-inhibiting in the MCF-7 cells, in order to present a new approach to the gene therapy for breast cancer. Methods: rAd-hTERT and rAd-TRF2 were constructed and the expression of hTERT mRNA and TRF2 mRNA were tested by FQ-PCR 48 hours after transfecting in MCF-7 cells. Apoptosis was observed by flow cytometry 1 to 6 days after transfection. Results: ①At 48 hours after transfection, the results of FQ-PCR showed that compared to PBS group, the expression of hTERT in rAd-hTERT group was obviously decreased and the inhibition ratio was about 86%, but TRF2 had not been obviously inhibited (P>0.05);the expression of TRF2 in rAd-TRF2 group was obviously decreased and the inhibition ratio was about 80%, but hTERT had not been obviously inhibited (P>0.05);in rAd-hTERT/rAd-TRF2 group, the inhibition ratio of hTERT and TRF2 were about 88% and 85%. Comparing rAd-hTERT/rAd-TRF2 group with rAd-hTERT group and rAd-TRF2 group, there were no significant differences of inhibition ratio between hTERT gene and TRF2 gene(P>0.05). Otherwise, comparing rAd-HK group, rAd-blank group with PBS group, there were no significant differences of inhibition ratio between hTERT gene and TRF2 gene(P>0.05). ②The result of flow cytometry showed that apoptosis was induced at the first day after transfecting in rAd-hTERT group and rAd-TRF2 group, the most obvious apoptosis was in the 3rd to 5th days,at the peak in the 5th day, and decreased in the 6th day after transfection. The apoptosis ratio of rAd-hTERT group was 46.2%, rAd-TRF2 group was 43.5%. The apoptosis ratio of rAd-hTERT/rAd-TRF2 group was 46.2% at first day, 68.5% at the second day, the most obvious apoptosis was in the 3rd to 6th days and was 77.6% in the 6th days in rAd-hTERT/rAd-TRF2 group. There were significant differences in apoptosis ratio in solo-inhibiting and connect-inhibiting(P<0.05). In addition, comparing rAd-HK group, rAd-blank group with PBS group, there were no significant differences in apoptosis ratio(P>0.05). Conclusion: ①Target sequence of RNAi which aimed at hTERT gene and TRF2 gene was designed efficiently, and the RNAi expression vectors were seen in vivo study efficiently and specifically inhibited the correspond gene expression and promoted cell apoptosis in MCF-7 cells. ②rAd-hTERT vector and rAd-TRF2 vector have no synergistical effect and antagoinstical effect on inhibiting hTERT gene and TRF2 gene mRNA expressing in MCF-7, but there was synergistical effect in terms of the induction of apoptosis. So association-RNAi-technique targeting to the genes of telomere length and stability can effectively promote tumor cell into apoptosis and inhibit breast cancer cell growth. RNAi technique of connecting correlation genes is a more effective gene therapy strategy.
