Objective To comprehensively evaluate the effect of health education on intervening iodine deficiency disorders(IDD) in Chinese pupils and housewives,and to provide a basis for prevention and intervention of the disease.Methods A computerized literature search was carried out in Chinese Biomedical Database (CBM),Chinese National Knowledge Infrastructure(CNKI),VIP,Wangfang and PubMed to collect articles published from 1997-2012 concerning the effect of education intervention on iodine deficiency disorders (IDD).The study was a self-controlled intervention study.Meta-analyses were performed to assess the knowledge on IDD prevention and behavior changes.Fixed and random effect models were employed to combine results after a heterogeneity test,and rate different(RD) was used as an indicator of the intervention effect.Results A total of 20 controlled before and after studies were included in our meta-analysis.The quality of individual studies was assessed by EPOC,and all studies were grade B.Because the heterogeneity was higher,each knowledge point was stratified analyzed according to the baseline rate.The results showed that the lower the baseline rate,the better the effect of the intervention.The analysis indicated that the RD for the main harm of IDD,the RD for the key measure to prevent IDD,the RD for the meaning of the pattern on the bags,and the RD for knowledge dissemination of IDD were increased by 35％,29％,27％,42％ and 47％,respectively.Conclusion Health education is helpful to Chinese pupils and housewives in improving their IDD related knowledge and their attitudes toward IDD.

Objective To study the optimum component proportion of media and the best fermentation conditions for the flocculatnt-producing strain B5. Methods Through single factor experiment to seek the best carbon sources, nitrogen sources and inorganic salts. Furthermore, through orthogonal test to select the best conditions for producing flocculants by strain B5. Results The best carbon source, nitrogen source and inorganic salt were glucose, (NH4)2SO4 and CaCl2, the content of glucose was 2.0%, the initial pH value of medium was 7.0, the temperature was 30 ℃, agitation rate was 160 r/min and culture time was 24 hours in flakes, 50 ml liquids (250 ml triangular flask), the inoculation volume was 0.2 ml. The flocculants produced by strain B5 under the best fermentation conditions has been furnished for multifarious waste water, the flocculating activities were from 88.4% to 97.2% and reached to the highest on the waste water of dairy farming. Conclusion The flocculants produced by the strain B5 is applicable to the waste water treatment.

Objective To explore the prothrombotic state of patients with ulcerative colitis(UC) and the relationship with phase,severity and Truelove classification.Methods 97 patients with UC were grouped by non-active phase and active phase;The latter were subdivided into mild,moderate and severe degree by clinical manifestation and TrueloveⅠ,Ⅱ,Ⅲ via endoscopy,vWF activity,fibrinogen and D-dimer were detected in all patients.Results vWF activity,fibrinogen and D-dimer were markedly higher in active phase than in non-active phase(t=14.137,3.435,3.625,respectively).There were no significant difference in vWF activity,fibrinogen and D-dimer between mild,moderate and severe degree and Truelove Ⅰ,Ⅱ,Ⅲ.Conclusion Prothrombotic state including hypercoagulation and secondary fibrinolysis correlates with the clinical phase of UC significantly.

Objective To study the mechanism of transforming growth factor ?(TGF-?) and its receptor in the pathogenesis of hepatocellular carcinoma and to explore its clinical significance.Methods 36 hepatocellular carcinoma tisssues and 36 corresponding cancer-adjacent normal tissues were investigated by immunohistochemistry for the expression of TGF-? and its receptor.Results The expression of TGF-? was distributed mainly in cytoplasm,while its receptor mainly in cellular membrane and cytoplasm.The expression of TGF-? in hepatocellular carcinoma was higher than that of normal tissues(P

We investigated health condition and evaluate the viability of Barthel's measuring scale for 1297 elder patients at 17 nursing homes.We nursed all patients by standards and performed a comparison study.The nursing percentages of highest and lowest levels were higher than the previous ones ( P ＜ 0.01 ),while the nursing percentage of normal level was lower than the previous one ( P ＜ 0.01 ).The cooperation between doctors and nurses became optimized through progressive patient care.Ideal nursing standard should be based upon the doctors' judgment and nurses' evaluation.The new standard will be more suitable for patients and easier to control for nurses.

Objective: This study aims to analyze the effects of catastrophic disease insurance (CDI), especially to evaluate the influences of CDI on the discrepancy of benefits between the patients covered by the Employee's Medical Insurance (EMI) and the Resident's Medical Insurance (RMI).Methods: The data used in the study are collected from the health insurance database of Zhuhai City in the years of 2012 and 2014.A descriptive analysis is made to depict the general situation of CDI in the city, and a logistic regression model is used to analyze the factors that affect the probability to get the benefits of CDI.Moreover, a triple difference model is built up to probe into the CDI's effects on the discrepancy of reimbursement ratio between patients covered by EMI and RMI.Results: The benefits of CDI favor the patients with old age, high medical expenditures and chronic diseases.When other factors are controlled, patients covered by EMI have lower probability to get CDI benefits than those covered by RMI.Within the patients with high medical expenditures who have gotten the CDI benefits, those covered by EMI enjoy higher reimbursement ratio than those covered by RMI, but CDI decreases the discrepancy by 3.2%.Conclusions: Since the CDI gives more favor to the vulnerable population and narrows the gap of the benefits between EMI and RMI, the policy improves the equity of health security.

Objective To study the clinical and pathologic features of aggressive angiomyxoma (AAM) and its occurrence, treatment and prognosis Methods The 8 cases of AAM were analyzed retrospectively, among which 6 cases in vulva, 2 cases in perineum, vagina and pelvis As well we performad immunohistochemical studies Results The neoplastic cells were at least focally immunoreactive for vimentin (7/7), smooth muscle actin (7/7), factor 8 (7/7), proliferating cell nuclear antigen (4/7), estrogen (3/7) and pregesterone (4/7) receptors All of the examined tumors were negative for S100 protein and cluster designation 68 Conclusions AAM is an uncommon mesenchymal tumor that preferentially involves the pelvic and perineal regions of females In immunohistochemical investigation the neoplastic cells of AAM exhibit fibroblastic and myofibroblastic features They are characterized by slow growth, infiltration of adjacent structures, absence of distant metastases, a tendency to recur locally and a fairly good prognosis Treatment should consist of wide surgical excision, as complete as technically possible

OBJECTIVE: To investigate the features of adverse drug reaction(ADR) in our hospital and evaluate the quality of ADR report in order to promote rational clinical drug use and find out the existing problems in the report. METHODS: Microsoft Excel was designed to analyze statistically the sex and age of the patients,category of the used drugs and the clinical manifestations of ADR in 311 cases of ADR report collected between 2002 and 2005.RESULTS: The occurrence of ADR induced by antibacterials ranked the first.ADR affecting skin and its appendages counted for 50% of the total.The numbers of ADR reports were found to be less than expected.CONCLUSIONS: Professional staff training should be strengthened,the use of antibacterials should be rationalized to lessen and avoid the occurrence of ADR.

Objective: To study the expression of Fas, Fas ligand (FasL) and IFN ? in gastric cancer and its possible significance. Methods: Fifty eight gastric paraffin wax embedded cancer tissues and fifty three normal tissues adjacent gastric cancer were tested for the expression of Fas and FasL protein by immunohistochemistry and IFN ? mRNA by in situ hubridisation respectively. Results: The positive rate of Fas in cancer cells of gastric cancer tissues was significantly lower than that in gastric epithelial cells of the tissues adjacent cancer(19.0% and 64.2%, respectively; ? 2=23.46, P = 0.00). The positive rate of FasL in cancer cells of gastric cancer tissues was significantly higher than that in gastric epithelial cells of the tissues adjacent cancer(63.8% and 45.3%,respectively; ? 2=3.83, P =0.05). The positive rate of IFN ? in cancer cells of gastric cancer tissues was significantly lower than that in gastric epithelial cells of the tissues adjacent cancer(0.0% and 49.1%,respectively; ? 2=37.16, P =0.00). Conclusion: The Fas-FasL system was unbalanced, and the expression of IFN ? was low in gastric cancer cells in this study. These may be related to the carcinogenesis of gastric epithelial cells and might be responsible for the immune escape of these cells.
