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.
3.Clinical Observation of Acupuncture plus Medicinal Application for Dysmenorrhea Due to Blood Stagnation Led by Cold
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.

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.

AIM To investigated the effect and mechanism of Houttuynium (HOU) on splenectomy animals. METHODS The models of splenectomy mice and splenectomy rats were made and delayed type hypersensitivity (DTH) reaction, ANAE (+) cell percentage of peripheral blood lymphocytes, Con A-induced thymus and groin lymph node lymphocyte proliferation, the amount of lymphocytes of groin lymph node,and T cell subpopulation in peripheral blood were measured. RESULTS HOU ig (60 mg*kg-1, 120 mg*kg-1) can strikingly enhanced delayed type hypersensitivity (DTH) reaction, ANAE(+) cell percentage of peripheral blood lymphocytes. strengthened Con A-induced groin lymph node lymphocyte proliferation, raised the amount of lymphocytes of groin lymph node in splenectomy mice. But the effects of them on Con A-induced thymus lymphocyte proliferation were not apparent. HOU ig (40 mg*kg-1, 80 mg*kg-1) improved Th subset, reduced Ts subset, and then modulated the rate of Th/Ts in splenectomy rats. CONCLUSION HOU strengthened the cellar immune function of splenectomy animals by promoting the compensating capability of lymph node and regulating T cell subpopulation.

Through defining the connotation of division and cooperation among medical institutions, this paper introduces the current status for division and cooperation among medical institutions of Britain, Germany, Singapore and USA. The advantages include excellent general practices, optimal health resource allocation, effective first treat-ment in community health facilities, and effective two-way referral. We analyzed the influence of some new policies on the division and cooperation among medical institutions such as medical association, managed care and the General Practices’ service contract. This provided a lot of experience and revelations, including the dynamics to promote the division and cooperation, the separation of outpatient services and inpatient services, privatization of primary medical institutions, division and cooperation between medical institutions and nursing, rehabilitation institutions, distinguis-hing the division and cooperation from hospitals alliance, and division and cooperation among medical institutions can not resolve the all issues in the medical care supply system.

Objective To investigate the risk factors of gallbladder carcinoma,so as to provide theoretical base for the prevention of gallbladder carcinoma.Methods The clinical data of 153 patients with gallbladder carcinoma (gallbladder carcinoma group) who were admitted to the Peking Union Medical College Hospital from January 2000 to December 2010 were retrospectively analyzed. A total of 300 patients with cholecystolithiasis (cholecystolithiasis group) and 300 patients without gallbladder carcinoma or cholecystolithiasis (control group)were collected and matched at the ratio of 1∶2 to conduct the controlled study.Data were statistically analyzed by the Chi-square test and conditional Logistric regression.Results Univariate analysis showed significant difference in age,history of cholecystolithiasis,postmenopausal age,accumulated menstrual period,giving birth or not and number of birth between gallbladder carcinoma group and control group ( x2 =58.22,180.14,9.59,24.30,18.66,15.17,P <0.05).Age,history of cholecystolithiasis,accumulated menstrual period and number of birth were the independent risk factors of gallbladder carcinoma (x2 =55.76,180.95,24.30,8.54,P < 0.05).The risk of having gallbladder carcinoma in patients who had a history of cholecystolithiasis was 34 times higher than those who did not have the history of cholecystolithiasis (OR =34.22).Late postmenopausal age (51 -55 years old),longer accumulated menstrual period ( ≥30 years),and the number of birth ( 3 times) were associated with higher risk of gallbladder carcinoma (OR =3.96,9.68,3.51 ). Age,course of cholecystolithiasis and accumulated menstrual period and number of birth were the risk factors of gallbladder carcinoma when comparing patients who have history of cholecystolithiasis in the gallbladder carcinoma group with those in the cholecystolithiasis group (x2 =70.66,16.66,11.59,4.69,P < 0.05 ).Age,course of cholecystolithiasis and accumulated menstrual period were the independent risk factors of gallbladder carcinoma ( x2 =64.29,8.82,5.58,P < 0.05).The risk of gallbladder carcinoma increased as the increase of age and course of cholecystolithiasis. The accumulated menstrual period ≥ 30 years was also a risk factor of gallbladder carcinoma. Conclusions Age,history of cholecystolithiasis,course of cholecystolithiasis,accumulated menstrual period and number of birth may be the risk factors of gallbladder carcinoma.For patients with age above 60 years and course of cholecystolithiasis above 3 years,cholecystectomy should be conducted to reduce the incidence of gallbladder carcinoma,and great importance should be attached to female patients with indications mentioned above.
