Background and Objective Keshan disease is clinically characterized as a dilated eardiomyopathy. We analyze the prevalence trend during last decade of hypertension and Keshan-disease in Yangzhuang village which was a Keshan-disease epidemic area.Method The survey including medical history,blood pressure and ECG were carried out every two years during the follow up 13 years.Results During follow up period,the total detection rate(hypertension:13.4 % vs Keshan-disease:10.7 %,?~2=8.555,P=0.002)and the accumulative rate of hypertension were higher than those of Keshan-disease,which was on the contrary to that before 1993,when increasing rate of Keshan-disease was higher than hypertension.Furthermore,the accumulative increasing rate of hypertension was 240.0%,which was higher than the national average level during corresponding period with no significant differences between female and male.Conclusion The detection rate of hypertension in Keshan disease epidemic area was higher than the average rate nation-wide.Whether the hypertension prevalence was re- lated to Keshan-disease needs further investigation.

Objective To evaluate the outcome of combination of intensive preconditioning regimen allo-HSCT with imatinib for treatment of Ph chromosome positive acute lymphocyte leukemia (ALL). Methods Between 2009 and 2010, 8 patients diagnosed as Ph+ ALL received allo-HSCT from HLA identical sibling during complete remission. Imatinib was added into the therapies of 5 patients.Seven patients received the intensive preconditioning regimen based on BuCy2, one patient received the regimen of TBI-Cy. A median of 6. 02 × 108/kg mononuclear cells and 3. 14 × 106/kg CD34+ cells were transfused. GVHD prophylaxis included cyclosporine A and methotrexate. Results All patients were well tolerant to the regimen without serious regimen-related toxicity. The median time of ANC≥0. 5 × 109/L was 15. 5 days, and that of PLT≥20 × 109/L was 19 days. Thirty days after allo-HSCT, all patients got donor engraftment successfully. Among 8 cases, 4 cases presented acute GVHD, 2 developed degree Ⅰ , one developed degree Ⅱ , and one developed degree Ⅳ. Seven patients were alive 100 days after allo-HSCT, 3 of whom presented chronic GVHD. At the end of following-up period, 6 patients were alive, among them, 3 patients were alive without relapse; 3 patients relapsed; Two patients died, one from acute GVHD, and one from leukemia relapse. Conclusion Combined intensive preconditioning regimen allo-HSCT with Imatinib was an effective treatment for Ph+ ALL, but the effect of anti-chronic GVHD of imatinib should arouse certain attention.

AIM: To investigate the feasibility and clinical effect of punctoplasty by using trabeculectomy punch combined with a novel RS tube for the treatment of punctal stenosis.METHODS: Totally 39 patients (39 eyes) with punctual stenosis were selected from October 2013 to October 2015 in the Second People`s Hospital of Foshan.All patients underwent punctoplasty by using trabeculectomy punch combined with a novel RS tube.These tubes were removed at 3mo after operation.A follow-up of 6mo was taken for final analysis.The fluorescein dye disappearance test score was recorded before the operation and at 1,3 and 6mo after the extubation.The curative effect of the operation at 6mo after the extubation was assess.RESULTS: Fluorescein dye disappearance test: the scores at 1,3 and 6mo after the extubation all decreased compared with the preoperative ones.The difference was statistically significant(P<0.05).At the last following up, 35 eyes (90%) were cured completely, 4 eyes (10%) were improved significantly, no patients recurred.Effective rate was 100%.No serious intraoperative and postoperative complications happened.CONCLUSION: Punctoplasty by using trabeculectomy punch combined with novel RS tubes is a safe and effective method for the punctul stenosis, which is easy to perform, with high success rate.

Objective To investigate the meaning of expression of apoptosis related molecules NFKBp65 and p53 and GPX1-mRNA in patients with Keshan disease(KSD).Methods Sixteen chronic Keshan Disease patients were enrolled in KSD group according to electrocardiogram,chest X ray film and clinical examinations on 15,September in 2009,and 23 healthy people were included in control group from physical examination taken in The Second Affiliated Hospital of Xi'an Jiaotong University.Fresh blood(5 ml)was collected from antecubital vein of all subjects in the fasting state.Total mRNA and protein of blood sample were isolated using Trizol.GPX Assay Kit was used to detect GPX enzyme activity,and GPX1-mRNA expression was determined by SYBR Real-Time PCR.Meanwhile,expression of apoptosis related molecules NFKBp65 and p53 were determined by Western blot.Results GPX enzyme activity decreased significantly in KSD group[(108.61±14.10)U]compared with control group[(122.78±11.89)U,t=2.874,P<0.05],GPX1-mRNA level of KSD group(0.553±0.299)notably KSD group(0.802±0.057)compared with control group[(1.065±0.355),t=6.829,P<0.01].p53 increased in KSD group(1.604±0.191)compared with control group[(1.137±0.186),t=3.033,P<0.05].Conclusiom Decreased GPX1-mRNA expression may result in lower GPX enzyme activity of patients with KSD.Thus oxidative damage increases and cadioeyte apoptosis is activated by activating apoptosis signal pathway.

Abstract: Objective To analyze the spatial-temporal characteristics of the active pulmonary tuberculosis (PTB) and the pathogenic positive PTB in Fuling District of Chongqing during the 13th Five-Year Plan period, so as to explore the clustering areas, and provide scientific basis for the precise prevention and control of tuberculosis in Fuling District. Methods The PTB registration data of 27 townships in Fuling District from 2016 to 2020 were collected. The descriptive analysis were used to describe the temporal and spatial distribution characteristics of patients, SaTScan9.0 and ArcGis10.6 was used for spatial-temporal scanning analysis and local auto-correlation analysis. The results were visualized by ArcGis10.6. Results A total of 4 038 case of active PTB patients were registered and a downward trend was observed in PTB during the 13th Five-Year Plan period in Fuling District. The average annual registration rate of PTB was 70.17/100 000, and the annual PTB registration rate declined by 8.21%. The peak of active PTB and etiological positive PTB were mainly concentrated in March and June respectively. The top five streets of cumulative active PTB patients registered were Lizhi street, Dunren street, Chongyi street, Ma 'an street and Jiangdong street, accounting for 60.18% of the total registered PTB patients during the 13th Five-Year Plan period. The top three average annual registration rates were Dunren street (101.35/100 000), Chongyi street (101.34/100 000) and Wulingshan Township (99.21/100 000). The registered PTB from 2016 to 2020 showed a global auto-correlation (Moran's I=0.64, P<0.0001). The "high-high" area of active PTB and the etiological positive PTB all covered Lizhi street, Jiangdong street and Longqiao street. By scanning analysis of spatial-temporal, the primary cluster of active PTB concentrated in the main urban area south of the Yangtze River in Fuling during January 2016 to December 2017, and the primary cluster of pathogenic positive PTB concentrated in the main urban area south of the Yangtze River in Fuling and Jiangdong street during January 2019 to December 2020. Conclusions During the 13th Five-Year Plan period, there was the spatial-temporal clustering of PTB in Fuling District, which mainly gathered in the main urban area south of the Yangtze River in Fuling district and surrounding streets centered on Lizhi street.
