Objective: To observe the clinical efficacy of DZWJY-1 type electronic moxibustion apparatus and traditional moxibustion in treating knee osteoarthritis (KOA). Methods: A total of 76 eligible patients were randomized into an electronic moxibustion apparatus group and a traditional moxibustion group, with 38 cases in each group. The electronic moxibustion apparatus group was intervened by DZWJY-1 type electronic moxibustion apparatus, and the traditional moxibustion group received moxa stick moxibustion for treatment. Neixiyan (EX-LE 4), Dubi (ST 35), Xuehai (SP 10) and Liangqiu (ST 34) were selected for both groups and the treatment was conducted 3 times a week for a total of 12 times. The visual analog scale (VAS) and the Western Ontario and McMaster Universities osteoarthritis index (WOMAC) scores were observed before treatment and after 6 and 12 sessions of treatment, respectively. Results: There were 4 dropout cases in the traditional moxibustion group. Therefore, this trial had 72 valid cases, including 38 cases in the electronic moxibustion apparatus group and 34 cases in the traditional moxibustion group, the differences in the baseline data between the two groups were statistically insignificant (P>0.05). After 6 and 12 sessions of treatment, the VAS scores decreased significantly with the increase of treatment sessions in both groups (all P<0.01), and the betweengroup differences were statistically insignificant at the same time points (both P>0.05). The pain intensity was evaluated using the weighted value of VAS score. The markedly effective rate was 47.4％ and the total effective rate was 89.5％ in the electronic moxibustion apparatus group, versus 50.0％ and 94.1％ in the traditional moxibustion group, and the betweengroup differences were statistically insignificant (both P>0.05). After 6 and 12 sessions of treatment, the total score and the component scores including pain, stiffness and difficulty moving in the WOMAC decreased significantly with the increase of treatment sessions in both groups (all P<0.01), and the between-group differences were statistically insignificant (all P>0.05). Conclusion: Electronic moxibustion apparatus and traditional moxibustion both are effective in reducing joint pain and improving joint function in KOA patients, and they are equivalent comparing the clinical efficacy.

Objective To apply Estimation and Projection Package (EPP) and Spectrum models for the estimation and projection on HIV/AIDS epidemics in areas with relatively low HIV/AIDS prevalence in China,and to explore the influences of antiretroviral therapy (ART) on the outputs of the models.Methods Taizhou prefecture in Zhejiang province was selected as the study site.Social and demographic data as well as all the information on HIV/AIDS epidemics in Taizhou prefecture were collected,managed,input to EPP and Spectrum models to estimate and project the HIV/AIDS epidemic in Taizhou prefecture.Impact of ART on the HIV/AIDS epidemic was also assessed.Results According to the estimates from both EPP and Spectrum model,the HIV/AIDS epidemic in Taizhou prefecture was at a relatively low level.HIV prevalence rates among men having sex with men (MSM) and injection drug users (IDU) were relatively high and rapidly increasing.It was estimated that 1773 (1384-2449) people were living with HIV in 2010 in Taizhou prefecture,with an overall HIV prevalence of 0.03％ (0.02％-0.04％).ART had reduced and would continue to reduce new HIV infections and AIDS deaths,but had no significant impact on the overall HIV prevalence and the numbers of people living with HIV and adults who were in need of ART.Conclusion EPP and Spectrum models seemed to be suitable and useful tools for estimation and projection on HIV/AIDS in Taizhou prefecture,and the results could provide reference for the further studies in other areas with a relatively low epidemic level of HIV/AIDS.ART appeared effective for HIV/AIDS prevention and control.

Objective To explore the expression of Toll-like receptor 4(TLR4) and tumor necrosis factor-α (TNF-α) on peripheral-blood mononuclear cells(PBMCs) and their correlation with myocardial perfusion in patients with diabetic cardiomyopathy (DCM).Methods The expression of TLR4 and TNF-α mRNA on PBMCs were examined by SYBR GreenⅠreal-time quantitative reverse transcription ploymerse chain reaction (RT-PCR), the levels of TLR4 and TNF-α were examined by flow cytometric analysis and enzyme-linked immuno sorbent assay (ELISA) on DCM group (n=20) , Type 2 diabetic group (n=22) and control group (n=20). Myocardial perfusion was visualized by single-photon emission computed tomography (SPECT). Results The expressions of TLR4 and TNF-α mRNA/protein on PBMCs in DCM group were significantly higher than in Type 2 diabetic group, and higher in Type 2 diabetic group than in control groups(P<0.05); summed stress score (SSS)and summed rest score (SRS) of myocardial perfusion in DCM group were significantly higher than in Type 2 diabetic group, and higher in Type 2 diabetic group than in control groups(P<0.01).The expression of TLR4, TNF-α was positively correlated with SSS (r=0.75,P<0.05;r=0.931,P<0.005) and SRS(r=0.78,P<0.005; r=0.789,P<0.005). SSS and SRS in DCM group were also positively correlated with soluble vascular cell adhesion molecule-1 (sVCAM-1) (r=0.728,P<0.005; r=0.738,P<0.005) but there was no correlation between SSS and SRS and brain natriuretic peptide, LVEF, E/A, HbA1c, FBG, FIN and LDL-C (P>0.05).Conclusion The increased expression of TLR4 and TNF-α mRNA/protein on PBMCs and increased serum sVCAM-1 is linked with reduced myocardial perfusion in DCM group. TLR4 and TNF-α may thus play a critical role in the myocardial perfusion inflammation injury in these patients.

Objective To understand the risk behavioral networks of newly reported HIV infections in Taizhou prefecture, Zhejiang province. Methods Newly reported HIV infections from May 2008 through March 2010 in Taizhou prefecture were invited to participate in a cross-sectional survey which requested numbers and contact information of individuals with whom they had had high risk contacts as well as risk behavioral acts with them. Persons having had risky contacts with HIV-infected cases were thereof approached to participate in this survey and to receive HIV testing.Those who tested positive for HIV were subject to further round of the surveys. Results A total of 267 HIV cases were newly reported during this study period. Among them, 191 participated in the survey and served as 'index cases', including 158 cases identified from routine HIV surveillance programs and 33 cases identified from the present survey. Heterosexual transmission was the primary transmission route (74.9%, or 143/191 ), followed by homosexual transmission ( 19.4%, or 37/191 )and injection drug use (5.8%, or 11/191 ). These 191 HIV cases reported a total of 1152 individuals with whom they had had risky contacts. They were able to provide contact information of 461 risk contacts. Of them, 129 received HIV testing and 61 (47.3%) tested positive for HIV. HIV prevalence was the highest among spouses or long-term sex partners of HIV cases (45.6%, or 47/103) and malesex partners of HIV-infected men having sex with men (MSM) (60.0%, or 12/20). Condom use wasvery low among them, with only 33.9% consistently using condoms for sex. Conclusion Newlyreported HIV infections in Taizhou prefecture reported a large and complicated risk behavioral networks and low condom use, suggesting a potential risk of HIV among these connected people,especially among MSM. Much efforts are needed to intervene these high risk subgroups and high risk behavioral networks.

OBJECTIVETo find out potential molecular targets for gallbladder carcinoma diagnosis and treatment by analyzing and comparing the proteins expressed in human gallbladder carcinoma tissue and benign gallbladder tissue.

METHODSProteomic analysis of 6 human gallbladder carcinoma tissues and 6 benign gallbladder tissues was carried out. Total proteins of the carcinoma tissue and benign gallbladder tissue were separated by two-dimensional gel electrophoresis (2-DE). The differentially expressed proteins were analyzed and identified by matrix-assisted laser desorption/ionization time of flight mass spectrometry (MALDI-TOF-MS). Immunohistochemistry was used to examine the expression of PEBP1 protein in an independent series of samples.

RESULTSProtein extracts of individual samples in each type of tissues were separated on two-dimensional gels. There were forty six differentially expressed proteins in the gallbladder carcinom tissues. Seventeen proteins were successfully identified by MS, in which nine proteins were overexpressed in tumors while the other eight proteins were underexpressed. The increased level of PEBP1 protein in gallbladder carcinoma was further confirmed by immunohistochemical analysis.

CONCLUSIONSeventeen differentially expressed proteins were successfully characterized by comparative proteomic analysis. Those results may provide scientific foundation for screening the molecular biomarkers which can be used in diagnosis and treatment of gallbladder carcinoma, as well as to improve its prognosis and provide a new clue for carcinogenesis research of gallbladder carcinoma.

OBJECTIVETo explore the potential molecular targets for diagnosis and treatment of gallbladder cancer by analyzing and comparing the proteomes expressed in human gallbladder cancer and benign gallbladder tissues.

METHODSThe proteins expressed were analyzed using two-dimensional gel electrophoresis. The differentially expressed proteins in tumors were also analyzed by mass spectrometry (MS). AnnexinA3 expression was examined by streptavidin peroxidase immunohistochemical technique on paraffin-embedded tissue sections from 50 patients of gallbladder cancer and 38 cases of chronic eholecystitis.

RESULTSProtein extracts of individual sample in each type of tissues were separated on two-dimensional gels. There were forty six differentially expressed proteins in the tissue samples of gallbladder cancer. Seventeen proteins were successfully identified by MS, in which nine proteins were overexpressed in tumors and the other eight proteins were underexpressed. The positive expression rates of annexinA3 in gallbladder cancer was significantly higher than that in chronic cholecystitis, and the difference was statistically significant (74.0% vs 21.1%, P < 0.01). In the gallbladder cancer, no correlation was obtained between annexinA3 and age, gender or histologicl type (P > 0.05), but overexpression of annexinA3 correlated significantly with those cases with a lower histological grading (40.0% vs 82.5%, P < 0.05); lymph node or distant metastasis (40.9% vs 100%, P < 0.05); or a shorter survival time after operation (50.0% vs 93.8%, P < 0.05).

CONCLUSIONSSignificant discrepancies in protein expression exist among gallbladder cancer and benign gallbladder tissues. AnnexinA3 plays an important role in the initiation and progression of human gallbladder cancer.
