Objective To understand the status quo of the health statistics human resources in Chongqing municipality. Methods The status quo of the health statistic human resources in Chongqing municipality was investigated by the national health statistics reporting system.The age,seniority,qualifications,specialty,job title,distribution,etc.in the health personnel were ana-lyzed by the SPSS17.0 statistical software.Results 74.89% of health statistic personnel were part-time workers.In the vast ma-jority of medical institutions,the number of health statistician was 1 or 2.As to the education background,73.50% of the total stat-istician number only got the junior college degree even below.Only 216 statistic personnesls′major fitted to the staff positions.Ba-nan district in the major city,Tongnan county and Dazu district in the west area,Wushan county in the east area,Dianjiang county and other counties in central area,and the new urban development area were relatively lack of human resources of the health statistic personnel.Conclusion The health statistic team in Chongqing municipality has low stability,inadequate staff and poor professional quality.The distribution of statistic personnel human resources is uneven among the five functional areas and various districts and counties.

OBJECTIVE To explore the relationship between cytokines(IL-1?,mIL-2R,IL-10) and hepatatis B virus(HBV) serum markers in patients with chronic hepatitis B(CHB).METHODS The serum level of IL-1?,mIL-2R and IL-10 in 65 patients with CHB was measured with chemiluminescence immunoassay(CLIA).RESULTS Of the patients with positive and negative HBeAg,the serum IL-1? and IL-10 levels were significantly higher than normal controls(P

Objective To explore the values of manual anastomosis with two operations out of anus in laparoscopic anal sphincter preserving resection of ultra low rectal cancer. Methods Radical excision of ultra low rectal cancer was performed with ultrasonic scalpel in 12 patients based on the concept of total mesorectal excision (TME) and ultra low coloreclal/anal anastomosis was performed applying manual anastomosis with two operations out of anus. Results All the operations were finished successfully, without conversions to open for surgery. One case had anastomotic leakage, and there were no bleeding and infection of abdominal cavity, anastomotic stenosis and other complications. The operating time was 185-310 (218 ±10) min, the blood loss was 160-450 (232 ±8) ml,the length of hospital stay was 9-14 (11 ±3) d. All patients were followed up 6-36(18 ± 2) months, local recurrence was not found but 1 case had liver metastasis.Conclusions The manual anastomosis with two operations out of anus in laparoscopic anal sphincter preserving resection of ultra low rectal cancer is safe,economical,effective,minimally invasive, and has the benefits of less bleeding during the operation and shorter hospital stay. It should be widely used.

Objective To investigate the value of CARE Dose 4D technique in decreasing radiation dose and improving image quality of multi-slice spiral CT in adult chest scanning.Methods 100patients of chest CT scanning were equally divided into study group and control group randomly.CARE Dose 4D Technique was used in study group.Effective mAs value,volume CT dose index (CTDIvol) and dose length product (DLP) were displayed automatically in machine while chest scanning; those values and actual mAs value of every image were recorded respectively.The image quality at apex of lung,lower edge of aorta arch,middle area of left atrium and base of lung on every image of 400 images was judged and classified as three level (excellent,good,poor) by two deputy chief physicians with double blind method,the image noise at corresponding parts was measured.Results While setting 80 mAs for quality reference mAs,the effective mAs value in study group most decreased 44 mAs than control group with an average decrease of 9.60( 12.0% ) ,CTDIvol with 4.75 mGy with an average decrease of 0.95 mC y( 11.0% ) ,DLP 99.50% in study group,with 98.0% in control group.But it was higher at apex of lung and base of lung,lower at middle area of left atrium,and similar at lower edge of aorta arch in study group than contrast group.The image noise were lower at apex of lung and base of lung in study group than control group (t =6.299 and 2.332,all P ＜ 0.05 ) ,higher at middle area of left atrium in study group than control group (t=3.078,P ＜0.05) and similar at lower edge of aorta arch in study group than control group (t =1.191,P ＞0.05).Conclusions CARE Dose 4D technique provides a function regulated mAs real-time on line,it not only raises utilization rate of radiation and decreases radiation dose,but also promises and increases image quality in chest CT scanning,and has some clinical significance.

Objective To summarize the diagnosis and therapeutic experience of insulinoma in order to improve the surgical success rate and prognosis. Methods The clinical data of 138 patients with insulinoma from 1966 to 2007 were retrospectively analyzed. Results In this group of patients, hypoglycemia of different levels and Whipple triad were detected. 64 patients expressed different psychic symptom, 12 patients' psychic symptom were still present after blood glucose normalized after operation. Fasting serum insulin values in 88 patients were measured, and the insulin release index was higher than 0. 3. Before operation, tumor was detected in 8 of 75 patients by B-ultrasound scan, and in 17 of 68 patients by CT, and in 5 of 10 patients by MRI. The intra-operative B-ultrasound (IOUS) examination was applied in 44 cases, and 43 cases were successfully detected. The operations included enucleation of insulinoma (n=88) , resection of the body and tail of pancreass (n = 44) , pancreaticoduodenectomy (n=2) , and biopsy (n=1). The blood glucose symptoms normalized postoperatively in 132 patients. The blood glucose rebound in 110 patients, but blood glucose normalized within 2 weeks. After operation, 20 patients developed pancreatic fistula, 32 patients developed acute pancreatitis. Conclusions Insulinoma could be qualitatively diagnosed according to Whipple triad and the insulin release index. Operations with IOUS were simple and effective methods to localize the tumors. The only way to cure insulinoma was operation, and IOUS guided operation could avoid main pancreatic duct and vessel injury, decrease post-operative complications.

Objective To investigate the expression of human leukocyte antigen F (HLA-F) in hepatocellular carcinoma (HCC) tissues and to evaluate its relation to clinicopathological features and prognosis of HCC.Methods HLA-F expression of tumor lesions and their adjacent normal liver tissues from 115 HCC patients were analyzed by immunohistochemistry,and its relationship between HLA-F expression and the clinicopathological features and prognosis of HCC patients was also analyzed.Results HLA-F expression was positive in 47.0％ (54/115) of the HCC lesions and in 10.6％ (7/66) of the normal liver tissues (x2 =24.799,P ＜ 0.05).HLA-F expression in HCC lesions was significantly correlated with portal vein invasions (x2 =7.644,P =0.006),tumor number (x2 =4.210,P =0.040) and patient sex (x2 =6.759,P =0.009).The mean survival time of the HLA-F positive HCC patients was 34.0 months(95％ CI:27.5-40.5 months),which was significantly shorter than that of HLA-F negative HCC patients(44.6 months,95％ CI:38.3-50.9months) (x2 =5.148,P =0.023).HLA-F expression was an independent predictor of overall survival of HCC patients.Conclusions Positive HLA-F expression is negatively correlated with the prognosis of HCC patients.

Objective To analyze the prevalence of cardiovascular disease (CVD) risk factors among nurses with high job stress in a Kunming tertiary hospital. Method The health data from 46 nurses who had gotten a medical examination between August 1 and November 30,2013 in the first people's hospital retrospectively analyzed .Results 76%of 46 nurses enrolled in this study had inordinately CVD risk factors,the top prevalence of CVD risk factors was dyslipidemia (58.9%),followed by hyperviscosity (45.5%),electrocardiographic abnormality (30.8%),overweight (19.2%),and hypertension (9.2%) . Moreover,there was significant differences of CVD risk factors among different departments ( <0.05),which the overall prevalence rate being highest among nurses working in the operating room. Conclusion The nurses with high job stress from tertiary hospital have high risks of CVD,therefore intervention measures should be taken to reduce the risk of CVD.
