Objective To survey the Keshan disease conditions and its trend in the historical serious illness areas of the disease in Arong Banner,and to provide epidemiological evidence for scientific prevention and control of Keshan disease.Methods According to the requirements of National Keshan Disease Surveillance Program,two villages in 2 townships of Arong Banner were selected as monitoring sites in 2012,population in monitoring sites was conducted clinical examination and electrocardiogram (ECG) tracings;suspected cases of Keshan disease were conducted chest X ray and ultrasound heartbeat graph examination.At the same time,residents' income and staple food structure were investigated.Results The abnormal rate of ECG was 7.92％ (66/833).The detection rate of cardiac enlargement was 20.00％ (9/45) by chest X ray,in which a slight increase was 8.89％ (4/45),moderate increase was 4.44％ (2/45) and severe increase was 6.67％ (3/45).The detection rate of Keshan disease patients was 132.05/10 000 (11/833),including latent Keshan disease [72.03/10 000 (6/833)] and chronic Keshan disease [60.02/10 000 (5/833)].In the ECG abnormal changes of Keshan disease cases,ST-T change and right bundle branch block were common,accounting for 100.00％ (11/11) and 63.64％ (7/11),respectively;frequent ventricular premature contraction was 2 cases,accounting for 18.18％ (2/11),degree I ° atrioventricular block and complete left bundle branch block was both i case,accounting for 9.09％ (1/11).Annual per capita income in Arong Banner was 8 100 yuan;dweller staple food was rice,flour and other grain crops,rice accounted for 70％-80％,flour 15％-25％ and purchased non-local grain accounted for 95％.Conclusions Keshan disease has been under control at a lower level in Arong Banner,but new latent and chronic Keshan disease occur slowly,gradually and gradually accumulated;life quality and dietary structure have influence on the incidence.In the future,we should pay more attention to Keshan disease and do a good job on prevention and control of Keshan disease.

The effects of antisense oligonucleotides of c-fos and c-jun on the proliferation of CNE-2Z cells and on the expression of protein kinase C-? (PKC-?) were investigated. With the interpoising of Lipofectin(LP), the CNE-2Z cells were added with antisens oligonucleotides of c-fos and c-jun. MTT method was used to test the cell proliferation and flow cytometry (FCM) to the PKC-a expression. The results showed that the inhibition of antisense oligonucleotides of c-fos and c-jun to CEN-2Z cells was gradually enhanced with its concentration and prolonging time increasing and that its lowest effective concentration of LP was 1.7 X 10~(-6)?g/ml, the lowest effective concentration was of antisense oligonucleotides of c-fos and c-jun 1.7 x 10~(-5)?g/ml, and the most effective time was 20 hours after treatment. The fluoresence of PKC-a and percentage of positive cells in the groups treated by antisense oligonucleotides of c-fos and c-jun decreased significantly. The results indicated that the autisense oligonucleotides of c-fos and c-jun could inhibit the proliferation of CNE-2Z ceUs the expression of PKC-?.

Objective To explore a new way to drain a postoperative abdominal abscess. Method Drainage catheter and sinography were employed to locate the site of the abscess, and a 10.2F~16F catheter with single or double lumen was inserted into the abscess by interventional technique. Result A 100% success was obtained for the 15 patients with 18 abscesses by inserting the drainage catheters, and all the abscesses were cured 7~65 days after drainage. Conclusions Compared with the surgical or percutaneous drainage, the present method is less traumatic, safer, more economical and effective, and it could be applies to all kinds of postoperative intraperitoneal abscesses which could not been drained adequately or with formation of sinus because of displacement of drainage tube.

Objective To evaluate the clinical features and prognosis of patients with complete left bundle branch block(CLBBB)following transcatheter device closure of ventricular septal defect(VSD)closure. Methods Clinical feathers of 11 patients with postoperative CLBBB in Department of Pediatric Cardiology,Guangdong General Hospital from January 2011 to December 2013 were collected and reviewed retrospectively. They were treated with dif-ferent protocol based on the appeared time of CLBBB occurrence and clinical symptoms. The patients were followed up, and the prognosis was recorded. Results The median age of 11 patients was 3. 9 years(3. 4 to 17. 5 years old). The median interval of intervention therapy to first attack of CLBBB was 2. 8 months(1 day to 25. 4 months). CLBBB oc-curred within 1 week to 1 month postoperatively in 4 patients,another 1 case suffered from CLBBB between 1 week to 1 month postoperatively,meanwhile 6 cases underwent CLBBB after 6 months postoperatively. The longest term of CLBBB attack postoperatively was 25. 4 months in 1 patient. The electrocardiograms on 5 patients returned to normal by only drug treatment. However,3 patients failed to recover with drug therapy,2 of them undertaken surgical procedure to re-move the occluder associated with VSD repair,1 patient recovered to normal and another converted to incomplete right bundle branch block. One of them refused to undertake surgical procedure and still bothered with persistent CLBBB. Another 3 cases did not receive special treatment due to the later attack of CLBBB(≥6 months)without clinical symp-toms. By the end of observation,the electrocardiogram(ECG)in 4 patients returned to normal,4 patients presented with persistent CLBBB. One patient's ECGs were presented with right bundle branch block. After ECG successfully returning to normal ECG by drug therapy,2 patients relapsed during follow - up,and 1 of them developed to an enlarging left ven-tricle and heart failure which led to death. Conclusions CLBBB may occur in short or long - term after VSD closure. ECG may become normal after early and appropriate treatment postoperatively. Systolic dyssynchrony and cardiac dys-function may be caused by persistent CLBBB. Therefore,patients with CLBBB after VSD closure should be treated ap-propriately without delay,and more frequent and longer follow - ups are required.

ObjectiveTo study the efficacy of transcatheter arterial chemoembolization (TACE) combined with surgical resection in the treatment of ruptured hepatocellular carcinoma (HCC).MethodsThe clinical data of 26 patients who presented with ruptured HCC to our hospital from January 2008 to December 2011 were retrospectively studied. These patients received TACE (n=19),surgical resection (n=7),and surgical resection after TACE (n=8).ResultsShock in the 19 patients who received TACE was promptly corrected and the vital signs were stabilized.On subsequent CT,the tumors shrunk in size.Salvage liver resection was carried out in 8 patients 1 month after TACE.After treatment,AFP decreased or became normalized,thus the treatment results were good. A one-stage liver resection was carried out in 7 patients. One patient died after operation and peritoneal metastases occurred in 4 patients. Conclusions TACE stopped bleeding from ruptured HCC efficaciously,reduced the need for open exploration,and improved the rate of resection of HCC.TACE combined with surgical resection significantly lowered the rate of abdominal tumor metastases.

In 1989, Fitz defined and classified severe acute pancreatitis (SAP) and he thought that surgical treatment of SAP is feasible. Since then, the strategy of treating SAP was a controversial issue over past decades. Currently, relevant literatures reported that medical or minimally invasive treatments are superior to surgical treatment, while it is too early to make the final conclusion because of the complexity of SAP. From 1989 to 2008, 1852 patients with acute pancreatitis were treated at the General Hospital of PLA, and the clinical data of 18 patients who died of SAP were retrospectively analyzed. Based on the analysis, we concluded that medical conservative therapy and surgical operative therapy should not be opposed to each other. Selecting ideal timing and appropriate operation on the basis of pathological changes of retroperitoneum and pancreatitis should be considered seriously, and the new concept of "miniaturization of trauma" should also be introduced in treating SAP.

Objective To explore the expression of TK1 in breast carcinoma and discuss its significance of carcinogenesis and progression in breast carcinoma and its relationship with Ki67. Method Using immunohistochemistry methods of SABC and S-P to detect the expression of TK1 and Ki67 in 89 cases of breast carcinoma tissue. Results Positive rate of TK1 in the breast carcinoma was 69.7% (62/89), and the expression of TK1 was significantly associated with lymph node metastasis, TNM stage and histological grade (P < 0.05), but it was not significantly correlated with age (P > 0.05). The expression of TK1 was not significantly correlated with Ki67 in the breast carcinoma (P>0.05). Conclusions Expression of TK1 is associated with carcinogenesis and progression, and it is a poor prognostic marker of breast carcinoma. TK1 and Ki67 are the indicators of cellular growth independently.

BACKGROUND: AG490 is a newly found JAK kinase inhibitor, which can compete with receptor tyrosine kinase for binding site to block JAK/STAT pathway, inhibit rejection-related cytokine activation such as interferon-gamma (IFN-γ) ultimately inhibiting rejection.OBJECTIVE: To evaluate the possibility and prospect of the AG490 as a potential immunosuppressor, explore its basic mechanism in comparison with Cyclosporine A (CsA).DESIGN, TIME AND SETTING: Comparative observation was performed at the Institute of Urinary Surgery, Fujian Union Hospital from October 2007 to April 2008.MATERIALS: AG490 was purchased from Sigma, USA.METHODS: Human peripheral blood lymphocyte (both T and B) were harvested from 8 healthy donors. Lymphocyte were isolated by density gradient method and cultured with phytohemagglutinin, interleukin-2 (IL-2) or mixed lymphocyte culture to induce human lymphocyte proliferation. MAIN OUTCOME MEASURES: ELISA was used to detect the concentration of IL-2, IFN-γ and IL-6 in different culture systems with the tyrphostin (AG490), CsA or FK506. RESULTS: IL-2 and IFN-γ in culture systems of phytohemagglutinin, IL-2 or mixed lymphocyte culture were inhibited by AG490 (P < 0.05), but IL-6 was not suppressed by AG490 (P < 0.05). This effect was similar to clinical CsA or FK506. CONCLUSION: AG490 may be a potential immunosuppressor.

Objective:To evaluate the application values of intraaortic palloon pumping in the treatment of acute left heart failure.Methods:From February 2013 to January 2016,102 patients in our hospital for diagnosis and treatment of acute left heart failure were selected as the research object,all the patients were equally divided into the observation group and control group with 51 patients in each group according to the random draw envelope principle.The control group was given routine drug treatment,the observation group was given intraaortic palloon pumping treatment based on the treatment in control group,the prognosis of two groups were observed and compared between two groups.Results:The total effective rate of observation group and control group were 96.1％ and 84.3 ％,respectively,which was significantly higher in the tobservation group than that of the control group (P＜0.05).The LVEF values in the observation group and control group after treatment were 65.22 ± 4.52 ％ and 58.20 ± 5.31％ respectively,which were significantly higher than those before treatment 45.29± 5.14 ％ and 45.20± 4.89 ％,and the LVEF value of observation group was significantly higher than that of the control group (P＜0.05).After 6 months' treatment,the incidence of death,refractory ischemia,malignant arrhythmia and other recent primary end points in the observation group was 5.9 ％,the control group was 21.6 ％,which was significantly higher than that of the observation group (P＜0.05).Conclusion:Aortic balloon pump implantation could promote the improvement of left ventricular function,improve the treatment effect,reduce the occurrence of recent primary end point event in the treatment of acute left heart failure.
