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 investigate the response of cryopreserved ovarian tissue after autologous implantation in mouse stimulated with gonadotrophin.Methods Thirty six female mice were randomly divided into three groups,with 12 mice in each group.In group of fresh ovarian tissue,fresh ovarian tissue was implanted into kidney capsule of mice:in group of cryopreserved ovarian tissue,ovarian tissue was implanted into kidney capsule of mice after cryopreserved by vitrification for two weeks.We investigated the response of ovarian tissue two weeks later after autologous implantation stimulated with gonadotrophin.Immunohistochemistry staining method was used to observe the expression of follicle stimulating hormone receptor.Results Before and after stimularian with gonadotrophin,the mature follicle rate of group of fresh ovarian tissue was 2.3%and 4.2%.that of group of cryopreserved ovarian tissue was 2.3%and 4.0%,and that of group of control was 2.6%and 5.8%.Regarding the percentages of mature follicle.there were significant differences after stimulation with gonadotrophin(P＜0.05).After stimulating with gonadotrophin the percentages of mature follicle were the same in the fresh tissue group,cryopreserved tissue group and control group(P＞0.05).The integrated optical density of follicle stimulating hormone receptor of fresh ovarian tissue in antrofollicle and pre-antrofollicle were 9408±2777 and 4531±1903.that of cryopreserved ovarian tissue were 9175±3093 and 4808±1386.and that of the control ovarian tissue were 8838±2064and 5516±1136 respectively.There was no significant difference between any two groups(P＞0.05).Conclusion The follicle stimulating hormone receptor is preserved by cryopreservation and transplantation,small pieces of ovarian tissue response to gonadotropin stimulation is normal.

Objective To summarize the clinicopathological features of ampullary cancer,and investigate the diagnosis and treatment strategy for ampullary cancer.Methods The clinical data of 187 patients with ampullary cancer who were admitted to the Peking Union Hospital from January 2000 to December 2010 were retrospectively analyzed.According to different surgical procedures applied,patients were divided into pancreaticeduodenectomy (PD) group (162 patients) and local resection group (25 patients).Survival curve was drawn by using Kaplan-Meier method,and the difference in survival rate between the 2 groups was compared by using Log-rank test.All data were analyzed by using t test or chi-square test.Results The positive diagnostic rates of B-ultrasound,computed tomography (CT),magnetic resonance imaging (MRI) and endoscopic retrograde cholangiopancreatography (ERCP) were 9.3％ ( 15/161 ),43.9％ (65/148),21.3％ (19/89) and 83.9％ ( 135/161 ),respectively.There were 87 patients with well differentiated adenocarcinoma,64 with moderate differentiated adenocarcinoma,27 with low differentiated adenocarcinoma and 9 with tubular canceration.There were no significant differences in survival rate between patients with ampullary cancer in T1 or T2 stage who received PD or local resection ( x2 =3.163,P ＞0.05).The prognosis of patients with ampullary cancer in T3 or T4 stage who received PD were superior to those who received local resection ( x2 =6.309,P ＜ 0.05 ).Conclusions Most of the ampullary cancer is well differentiated adenocarcinoma,and ERCP has a higher diagnostic rate than B-ultrasound,CT and MRI.Local resection is an ideal treatment for patients with ampullary cancer in T1 or T2 stage,while for patients with ampullary cancer in T3 or T4 stage,PD is the first choice of treatment.

AIM: To investigate the effects of Tangmoning (TMN) Granule on nerve conduction velocity, red blood cell sorbitol (RBC S) level in diabetic rats and probe the mechanism of prevention and treatment of diabetic peripheral neuropathy. METHODS: The model of diabetic rat was induced by strepotozotocin. The animals were randomly divided into six groups:TMN minimal dose group, TMN mild moderate dose group, TMN maximal dose group, methycobal group, model group and normal control group. All TMN groups were treated with TMN Granule through tube feeding (2.95 g/kg、5.90g/kg、11.80g/kg). Methycobal group was treated with methycobal tablets through tube feeding (0.14mg/kg). The duration of treatment was 3 weeks. The caudal nerve conduction velocity, RBC S content were investigated before and after treatment. RESULTS: It showed that TMN Granule could increase the caudal nerve conduction velocity significantly in the maximal dose group and the mild moderate dose gorup ( P

Aim The kinetics of nicotinic acetylcholine receptor (N-AChR) was stadied. MethodsThe saturation experiments of Torpedo electric organ N-AChR were taken with125I-?-BuTX. The results were calculated by Scatfit program. Experiments were thenperformed to study the kinetics of dissociation of ?-BuTX and nicotine from N-AChR,respectively. When their binding reached saturation, an excess of 1000 times ?-BuTX ornicotine was added. The saturation binding properties of the N-AChR extracted fromleg muscles of the 13th day chick embroys and optic lobes of the 20th day chick em-broys were studied. The results were calculated by Scatfit program. The othe experi-ments were taken to observe the competition between mcotine and 125I-?-BuTX forbinding with Torpedo, optic lobe and skeletal muscle of the chick N-AChRs. ResultsThe saturation experiments of Torpedo electric organ N-AChR resulted in a Scatchardplot of hyperbola which responded to the model of two kinds of receptor with on eli-gand.The difference of and B max between high affinity binding site and low affnitybineing site was significant. The dissaciation experiment showed that the fast dissocia-tion rate of tow ligands was 500 times more than that of the slow dissociation rate. Thisresult suggested that there may be two subtype N-AChRs.The saturation bindingproperties of N-AChR of leg muscles and optic lobe of the chick embroys revealed aScatchard plot of two kinds of N-AChR indicating a single type of site. The bindingaffinity of receptor of optic lobe was 100 times more than that of muscles. In competi-tion for Torpedo receptor by nicotine and 125I-?-BuTX, the values of IC50 were different:which suggested that two kinds of receptor sites were existent. In competition ofNicotine and 125I-?-BuTX for optic lobe and skeletal muscles of the chick N-AChR, thevalue IC50 of skeletal muscles N-AChR was 7. 7 times higher than that of optic lobe. Itindicated that two kinds of N-AChR subtype existed in the optic lobe and in theskeletal muscles of chick respectively. Conclusion N-AChR of Torpedo electric organcontains two kinds of subtype receptors. N-AChR of optic lobe of chick embroys is onesubtype receptor, and N-AChR of skeletal muscles of chick embroy is another subtypereceptor.

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.
