Objective To investigate the risk factors of postoperative complications of delayed hemorrhage,perforation and digestive tract stenosis after endoscopic submucosal dissection (ESD).Methods The complete data of 793 patients with digestive tract disease who underwent the endoscopic submucosal dissection in the Department of Digestive Surgery in our hospital from January 2011 to December 2014 were retrospectively analyzed.All of the patients were divided into delayed hemorrhage group (n =67) and nonbleeding group (n =726);perforation group (n =47) and non-perforation group (n =746);and digestive tract stenosis group (n =38) and non-stenosis group (n =755).The clinical basic data,lesion related data,and operation related data were independent risk factor and analyzed by single factor analysis and Logistic multiple factor regression analysis.Results The incidence of delayed bleeding,perforation and stenosis in patients with ESD were 8.45％,5.93％,and 4.79％,respectively.The results of single factor analysis:the risk factors for delayed bleeding were long-term use of anticoagulant drugs,gastric sinus disease,lesion diameter,and lesion excision (P ＜ 0.05).The risk factors for postoperative perforation were the diameter of the lesion and the time of operation (P ＜ 0.05).The risk factors of digestive tract stenosis were the esophageal lesions,the diameter of the lesion,and the depth of the lesion to the intrinsic muscle layer (P ＜ 0.05).The results of multi factor Logistic regression analysis:the risk ranking of risk factors for delayed bleeding was gastric antrum occurrence lesion ＞ lesions graded resection ＞ long-term use of anticoagulants ＞ lesion diameter (≥5 mm).The risk ranking of risk factors for perforation was operation time (≥90 mm) ＞ lesion diameter (≥5 mm).The risk ranking of risk factors for digestive tract stenosis was esophageal lesion ＞ lesion diameter (≥ 5 mm) ＞ lesions depth to the muscularis propria.Conclusions For long-term anticoagulation,gastric antrum and fractional resection lesions of patients should pay attention to delayed bleeding.Patients with long operation time are easy to cause postoperative perforation.For long-term anticoagulation,gastric antrum and fractional resection lesions of patients should pay attention to delayed bleeding.

Objective To investigate the occurrence of cesarean section (CS) among reproductive age women in last thirty years, and explore the factors related to high CS rate. Methods Population proportional to size sampling method was employed in sampling. The sampled women were interviewed face to face. Data were double entered by EPIDATA 2.1 and analyzed by SPSS 11.5. Results The CS rate continuously increase from 0.9% in 1971-1980 to 20.2% in 2001-2002 and the speed is more and more rapid. More and more CSs were required by the women themselves and the rate increased from 19.3% in 1971-1985 to 49.7% in 2001-2002. Logistic regression analysis showed that women who were less than 30, senior high education or above and white-collar or jobless women had more than 8 times of antenatal visits, lived in eastern region and had B-ultrasound exam, were more likely to have caesarean section. Conclusions The caesarean section rate was increasing rapidly in the last thirty years especially after 1990. There are two reasons for this increase, on one hand caesa- rean sections with medical indications increase because of the progress of perinatal care and related technology; on the other hand unnecessary caesarean sections increase because of some social and demographic factors, which result in more caesarean section required by the pregnant women.

Objective To understand the trends of institutional delivery in recent 30 years in China and find out the main social and demographic factors. Methods Two-staged PPS method was employed for sampling; Uniform questionnaire was drafted and direct interview was adopted to collect the information. Results The institutional delivery rate was increasing rapidly with time, especially from 1990's, which had climbed to 82% in the last three years, but it was still unsatisfactory in the central and western areas. Meanwhile, most women who delivered outside the hospital were assisted only by birth attendants/village doctors or family members/friends in labor. Factor analysis showed that the women s education and occupation and their husbands, the gap of education between the couples, and the antenatal care could significantly affect their choice for where to deliver. Conclusions Great improvement had been achieved in the last several decades, and both individual characteristics, community and health facility could have influences on the women s decision on where to give birth.

Objective To discuss the observation and nursing of adverse reactions in chronic myelocytic leukemia patients receiving imatinib therapy.Methods Adverse reactions were observed and recorded in 193 chronic phase myelocytic leukemia patients who received imatinib therapy,and corresponding treatment and nursing were given to them.Results Among 193 patients,more than 60％ of patients had adverse reactions,of which,54％ of patients showed gastrointestinal adverse reactions including nausea,vomiting,anepithymia and diarrhea; 22％ of them had muscle and bone pain; 7％ had rash; 65％ got edema.After proper treatment and nursing,all adverse effects obtained satisfactory remission.Condusions During the treatment course of chronic myelocytic leukemia patients using imatinib,careful observation of any possible adverse reactions,and giving corresponding treatment and nursing can facilitate good compliance and longterm remission of patients.

Objectives To investigate the clinical features of Guillain-Barré syndrome (GBS) in children from Shen-zhen. Methods The clinical manifestations, results of electrophysiological tests and prognosis of 28 GBS patients from July 2002 to July 2012 were retrospectively analysed. Results Of 28 children, 16(57.1%) had preceding acute upper respiratory infection for 3-14 days but no patient had acute gastroenteritis. One had received HBV vaccination in 2 weeks before the onset of GBS. The peak season for GBS is spring. According to the clinical presentations and the neurophysiological results 17 patients had demyelinating neuropathy, 5 acute motor axonal neuropathy, 2 acute motor sensory axonal neuropathy, 3 Miller-fisher syndrome, and 1 polyneuritis cranialis. 14 (50.0%) patients suffered from pain in limbs which is the most nota-ble symptom in the early stage. Intravenous immune globulin (IVIG) and steroids were given during the acute phases in the majority of the patients, and assisted ventilation was performed in 2 patients due to respiratory muscle paralysis. No diffe-rence was found in Hughes scores, average hospitalization durations, and the prognosis between patients with GBS variants patients and patients with classic GBS. Conclusions Children with GBS in Shenzhen area have different clinical features.

To carry out pathologic diagnoses and whole-genome sequence analyses of the Jaagsiekte sheep retrovirus (JSRV) in Xinjiang, China, we first observed sheep suspected to have the JSRV. Then, the extracted virus suspension was observed by transmission electron microscopy (TEM). Total RNAs from lungs of JSRV-infected sheep were extracted and reverse-transcribed using a cDNA synthesis kit. Six pairs of primers were designed according to the exogenous reference virus strain (AF105220). Reverse transcription-polymerase chain reaction was carried out from JSRV-infected tissue, and the whole genome of the JSRV sequenced. Our results showed: flow of nasal fluid ("wheelbarrow test"); different sizes of adenoma lesions in the lungs; papillary hyperplasia of alveolar epithelial cells; alveolar cavity filled with macrophages; dissolute nuclei in central lesions. TEM revealed JSRV particles with a diameter of 88 nm to 125. 4 nm. The full-length of the viral genome sequence was 7456 bp. BLAST analyses showed nucleotide homology of 96% and 95% compared with that of the representative strain from the USA (AF105220) and UK (AF357971). Nucleotide homology was 89.8% and 89.9% compared with the endogenous Jaagsiekte sheep retrovirus, Inner Mongolia strain (DQ838493) and USA strain (EF680300). The specific pathogenic amino-acid sequence "YXXM" was found in the TM district, similar to the exogenous JSRV: this gene has been reported to be oncogenic. This is the first report of the complete genomic sequence of the exogenous JSRV from Xinjiang, and could lay the foundation for study of the biological characteristics and pathogenic mechanisms of the pulmonary adenomatosis virus in sheep.
