A preliminary survey was done in 1980 in Jijiaba Village before the dike was built . The dike of 2. 5 km in length and 4m high was built along Baiyang River by the end of 1980 . The molluscicide NaPCP was used for snail control from 1981 to 1984 . After the entire control measures were completed in 1984, a follow-up survey was conducted as to measure the impact of control measures on prevalence of schistosomiasis and population of snail from 1985 to 1989 . All of the results suggested that these control measures were very successful. The transmission of schistosomiasis in this area has been prevented since 1984 .

Objective To compare the efficacy and safety of 2 mg/d and 4 mg/d of terazosin in the treatment of benign prostatic hyperplasia (BPH) with lower urinary tract symptoms (LUTS).Methods A total of 120 BPH patients were randomly divided into 2 groups receiving 2 mg or 4 mg terazosin per day for 2 months. Arterial blood pressure, International Prostatic Symptom Score (IPSS) and peak flow rate (Qmax) before and after treatment were compared while side effects were estimated. Results Forty-six patients receiving 2 mg and 54 patients receiving 4 mg terazosin completed this study. Patients' age and pre-treatment blood pressure, IPSS and Qmax had no difference between the 2 groups. The improvement of IPSS (including obstructive score, irritating score and total IPSS) and Qmax was significantly better in 4 mg group. The percentage of patients experiencing greater than 30% improvement in Qmax in the 4 mg treatment groups was significantly higher than that of the 2 mg group (46.3% vs 23.9%, P=0.02). Side effects were rare and mild in both groups.Conclusion The improvements of IPSS and Qmax are significantly greater in 4 mg treatment of terazosin than that of 2 mg with no obvious increase of side effects.

Objective To investigate the relationship between 24-hour ambulatory blood pressure and urine microalbumin(UMA)level in the elderly with non-diabetic essential hypertension.Methods One hundred elderly cases with essential hypertension were selected from the Department of Geriatrics,the Sixth People's Hospital,Shanghai and divided into two groups,one with UMA less than 30 mg/24h,and the other with UMA equal to or greater than 30 mg/24h.Ambulatory blood pmssure,serum level of creatinine (sCr),UMA and other characteristics were measured for all the subjects studied and compared to find possible relationship between blood pressure and UMA.Results Level of sCr,diastolic blood pressure at night (nDBP),24-hour average blood pressure,average blood pressure at night were all significantly higher in the group with UMA equal to or greater than 30 mg/24h than that with UMA less than 30 mg/24h(P<0.05 or P<0.01). Multivariate logistic regression analysis indieated that both sCr and nDBP were indispensable predictors for high microalbuminuria in patients with essential hypertension.Conclusions Ambulatory blood pressure monitoring,especially blood pressure variation at night,has more important predictive value for severity of renal damage caused by hypertension in the elderly with non-diIlbetic essential hypertension.

Transforming growth factor-?(TGF-?) is a kind of multifunctional cytokine that regulates cell growth,differentiation,cellular senescence,apoptosis,wound healing and embryo development.As a tumor suppressor,deregulated or aberrant TGF-? signaling has been strongly implicated in human solid tumors,as well as in normal and malignant hematopoiesis.TGF? exerts an inhibitory role during the whole procedure of hematopoiesis.As a cell cycle inhibitor,it maintains cells in a quiescent state and can downregulate expression of hematopoiesis activators and oncoproteins.In malignant hematopoiesis,altered expression of coactivators or corepressors involve in TGF-?-induced transcriptional responses and loss/disruption of TGF-? target gene expression.Then malignant cells grow and differentiate abnormally.In acute promyelocytic leukemia,PML-RAR? may inhibit TGF-? signaling through inhibition of cPML and nPML.Degradation of PML-RAR? by ATRA restores this signaling pathway.

Objective The aim of this study was to assess the current situation and master degree on medical statistics among the medical correlation personnel, in order to provide useful information for transformation of education towards the medical correlation personnel . Methods Using cluster random sampling method to select 358 the medical correlation personnel who were recruited from health institutions in Chongqing to respond to the questionnaires. Questionnaire including respondent basic information, statis-tical knowledge and statistical knowledge needs. The data of the survey were analyzed by chi-square test, descriptive statistics analysis. Results 94.7% of the surveyed used statistical knowledge in the process of work or study. The main concentration of medical statistical knowledge utilization rate, the proportion of receive professional education or training courses of medical statistics and the willingness to participate in specialized training of medical statistics is 20-30 age group, No Title group, Master and over group andStudents group. As for ten categories of common statistical methods, thirty percent of people can use them skillfully, but the majority of the more advanced statistical analysis methods cannot be used or have never heard of. The greatest demand for learning ten kinds of common statistical methods is calculating cor-rectly through statistical software. Conclusion The vast majority of medical personnel need to use medical statistics in the actual work and study, but they have a lower mastery of statistical methods. Therefore, we should strengthen the medical statistics teaching and training for medical personnel.

AIM: To investigate the short-term efficacy and safety of sulfasalazine (SASP) 3 g per day in the treatment of patients with mild and moderate ulcerative colitis (UC). METHODS: 122 patients were treated with SASP ( 1 g, t.i.d.) for 6 weeks. The data of clinical manifestations, colonoscopic and histological involvements were compared before and after the treatment of UC. The short-period efficacy and adverse reactions were evaluated in 110 patients. RESULTS: The therapeutic project was carried out in the 110 out of 122 patients. After 110 patients were treated for 6 weeks, the clinical, colonoscopic and histological remission were 71.8%, 21.8% and 16.4%, respectively. Among the 79 patients with clinical remission, 58.2% and 67.1% of them remained grade 1 in colonoscopic and histological findings, respectively. The curative rates and the effective rates were 63.9% and 82.0%, respectively. Among the 122 patients treated with SASP, 21 of them ( 17.2%) had adverse reactions. Except 4 patients suffered urticaria and leukopenia, no patients quitted the treatment because of obvious adverse reaction. CONCLUSION: SASP ( 3 g per day) can be an effective and safe medicine in treatment of patients with mild and moderate UC, but more than half of the patients in clinical remission still have light inflammation in colonoscopy and histology.
