Objectiye To explore the diagnostic and therapeutic methods of anastomotic leakage after low anterior resection of rectal cancer. Methods The clinical data of 16 cases with anastomotic leakage after sphincter saving operation which was performed through anterior resection for patients with lower rectal cancer were retrospectively analyzed. Results Among the 186 cases of low anterior resection of rectal cancer,16 cases occurred anastomotic leakage,incidence rate was 8.6% ;14 cases healed through local douche and drainage; 1 case healed by emergency operation and upper colostomy after bacterial peritonitis;only one elderly patient died for infectious shock. Conclusion Anastomotic leakage was the severe complication of low anterior resection,and timely correct treatment and doing well safety precautionary measures before operation could reduce the incidence rate of anastomotic leakage.

Objective To investigate the expression of insulin-like growth factor-binding protein-5( IGFBP-5) in full-term rats with hyperoxia-induced chronic lung diseases(CLD) and its mechanism.Methods Ninety-six full-term rats were randomly exposed to hyperoxia (hyperoxia group)and room air(room air group).CLD was induced by hyperoxia exposure.RT-PCR and immunohistochemical metho -ds were used to detect the expression of IGFBP-5 at 1,3,7,10 ,14 and 21 days after exposure.Results The expression of IGFBP -5 was dynamic, the expression of IGFBP-5 increased significantly in hyperoxia group compared with room air group at 3 d to 10 d after hyperoxia exposure (P

Objective To investigate and analysis the prevalence rate of hospital infection and community infection,and to reduce the incidence of hospital infection.Methods First we investigated hospitalized patients in September 9,2013 by two ways which in-clude bedside investigation and reviewing the medical records;and then described the prevalence case of infection and the usage of antimicrobial agent by descriptive approach.Results Seven hundred and seventy patients were investigated with the rate of 100.00%;18 patients were hospital infection cases,the infection rate was 2.34%;most of the hospital infection cases was occur in lower respiratory tract;228 patients were community infection cases.The infection rate was 29.61%;the primary affected areas of community infection were respiratory and gastrointestinal tract;the structure of hospital infection pathogens were almost the same with the community infection,most of them were G- bacteria;186 patients were used antimicrobial agent in that day,the usage rate was 24.16%.Conclusion Promoting the managements of high risk departments and susceptible affected areas,making relevant rules of operation are the focus of our works in the future.

Objective To explore the relationship between osteopontin (OPN),its downstream product thrombin-cleaved osteopontin (NTOPN) and radiographic changes in osteoarthritis (OA).Methods The levels of OPN and NTOPN in serum and synovial fluid were tested by enzyme-linked immuno sorbent assay (ELISA) kit in 22 OA patients and 21 health controls.The correlation between the above parameters and clinical data such as radiology changes of OA patients was analyzed.Results The serum level of OPN in the OA group was positively correlated with C reactive protein (CRP) (r =0.574,P =0.005).The serum level of OPN in the OA group was slightly lower than that in the healthy control group [(1.8 ± 0.5) μg/L vs (1.7 ± 1.1) μg/L,P ＞ 0.05].Similarly,the serum level of NTOPN in the OA group was significantly higher than that in control group [(21.1 ± 11.7) μg/L vs (14.7 ± 3.6) μg/L,P ＜ 0.05].Meanwhile,serum NTOPN level in female patients was significantly higher than that in male patients [(23.2 ± 11.80) μg/L vs (11.1 ± 4.9) μg/L,P ＜ 0.05].In synovial fluid of OA group,the level of OPN was (7.75 ± 2.33) μg/L,NTOPN was (0.91 ± 0.49) μg/L and the ratio of NTOPN/OPN was 0.12 ± 0.08.The level of OPN of synovial fluid in the OA group was positively correlated with CRP (r =0.574,P =0.005).NTOPN-to-OPN ratio of synovial fluid in the OA group was positively correlated with Kellgren-Lawrence grade (r =0.535,P =0.022).Conclusions The serum level of OPN is correlated with severity of inflammation in the OA patients.Meanwhile,NTOPN-to-OPN ratio of synovial fluid is correlated with OA severity.As a downstream bioactive product of OPN,NTOPN may play an important role in OA pathogenesis.Whether these parameters can be used as predictors of joint lesion severity and inflammatory status is worth further study.

Objective To study the effect of Thy-1.1 stem cell transplantation on endothelial hyperplasia and restenosis.Methods Thirty 4-6 weeks male SD rats were sacrificed to obtain the Thy-1.1 stem cells.Carotid artery were injured by ballon in sixty female SD rat's were randomized to receive stem cell transplantation(5?10~6 Thy-1.1,n=30)or saline approach(n=30).About 5?10~6 Thy-1.1 stem cells were injected into the injured arter- y after carotid artery injury;while the control rats underwent carotid artery injury and was injected the same amount of saline.The animals were sacrificed,3,7,14,21 and 28 days after balloon denudation.The samples of carotid artery were harvested for pathological examination,RT-PCR and in situ hyhridzation(ISH)were used to detect the transplanted cells in the injured artery.Results The intimal thickness was thinner in stem cell transplantation group(I/M,Stem cell transplantation group:2.06?0.28 vs control group 2.42?0.19,P

ObjectiveTo explore the effect of personality and psychosocial factors on irritable bowel syndrome (IBS).MethodsPersonality and psychological status of 46 IBS patients and 32 healthy individuals were evaluated with Eysenck Personality Questionaire (EPQ), Symptom Checklist-90 (SCL-90) and Life Events Scale (LES).ResultsIn EPQ, E (extroversion-introversion) scores of IBS group were lower than those of control group; N (neuroticism) scores of IBS group were significantly higher than those of control group (P<0.01). In SCL-90, the scores of somatization, compulsion, anxiety, depression and etc. were higher than those of control group (P<0.05). The frequency of meeting negative life events, the quantity of stimulus of meeting negative life events and the total quantity of stimulus of meeting life events of IBS patients within one year until episode were significantly higher than those of control group (P<0.01).ConclusionPersonality psychological characteristics and life events before illness are associated with the morbidity of IBS.

Objective To explore the application of single-person operated mammotome minimally inva-sive surgery in treatment of benign breast lesions. Methods Clinical information of 403 patients were collected and retrospectively analyzed. 262 patients receiving ultrasound guided single-person operated mammotome mini-mally invasive surgery for benign breast masses were selected as the treatment group,141 patients undergoing open surgery for treatment of benign breast masses were selected as the control group.Operative time, introopera-tive blood loss,length of stay,postoperative healing time, as well as the occurrence of complications were com-pared between the two groups. Result Compared with the control group, the operative time was shorter, the in traoperative blood loss was less, the scar size and the postoperative healing time were shorter for the treatment group. The difference had statistical significance (P<0.05).The rate of postoperative pain, local ecchymosis, local infection and breast deformity for the treatment group was significantly lower than those of the control group (P<0.05). The difference had statistical significance (P<0.05). The recurrence rate between the two groups had no sta-tistical significance (P>0.05). Conclusions Single-person operated Mammotome minimally invasive surgery has the advantages of good operative time,good cosmetic effects, small surgical trauma, less blood loss, fast postoper-ative healing and few complications, which is worthy of clinical application.
