Objective To evaluate application effectiveness of quality control circle (QCC)in increasing the face mask wearing rate of hospitalized pulmonary tuberculosis (TB)patients.Methods Nine nurses in department of tu-berculosis formed a ‘circle’,the theme of ‘improving the face mask wearing rate of hospitalized pulmonary TB pa-tients’was established,rectification measures were formulated and implemented,face mask wearing rates of pa-tients before and after implementing QCC activities were analyzed statistically.Results The face mask wearing rate of hospitalized pulmonary TB patients after implementing QCC activities was higher than that before implementing QCC activities (87.50% [147/168]vs 65.54%[116/177],P <0.05).The abilities of every ‘circle member’have been improved in the following aspects:problem-solving skills,sense of responsibility,communication skills,self-confidence,team working,enthusiasm,quality-control techniques,and cooperation abilities,the total average score increased from 23.78 before implementing QCC to 33.78 after implementing QCC.Conclusion QCC activities can not only improve the face mask wearing rate of hospitalized pulmonary TB patients,but also enhance circle mem-bers’quality-control skills and team spirit.

OBJECTIVE: To investigate the effects of Zhenqing Capsule (ZQC), a compound traditional Chinese herbal medicine, in treating type 1 diabetic rats with peripheral neuropathy. METHODS: Type 1 diabetes was induced by caudal vein injection of high-dose streptozotocin in 30 male Wistar rats. The thirty diabetic rats were randomly divided into three groups: ZQC-treated group, untreated group and aminoguanidine-treated group. Another group of 10 rats was taken as normal control. After 10-week treatment, the changes of body weight and fasting plasma glucose level were measured, and the serum MDA level and the changes of neurological electrophysiology were analyzed. The samples of sciatic nerve in diabetic rats were taken for morphological observation. RESULTS: The MDA level in type 1 diabetic rats was notably reduced in ZQC-treated group as compared with the untreated group (P<0.01). Compared with the untreated group, ZQC could improve the electrophysiology of sciatic nerve including conduction velocity (P<0.05), latency (P<0.01) and wave amplitude (P<0.05). The nerve myelin staining results showed that segmental demyelination of the nerve fibers in ZQC-treated group was not as serious as that in the untreated group. CONCLUSION: ZQC can obviously ameliorate the neurological electrophysiological function and the pathological changes of peripheral nerve in type 1 diabetic rats through the removal of free radical and resistance of lipid peroxidation.

OBJECTIVE To investigate the distribution and drug resistance status of urinary tract infections in diabetics and offer scientific basis for reasonable usage of antibiotics.METHODS Pathogenic bacteria isolated from specimens of 236 cases with urinary tract infections were identified and drug susceptibility tests were performed.RESULTS Among 236 strains of pathogenic bacteria,Escherichia coli rated the top one,59.7%.Then Enterococcus rated the second and accounted for 10.6%.The isolates were susceptible to imipenem and amikacin and showed higher drug-resistance to the other common antibiotics.CONCLUSIONS Diabetics easily suffer from urinary tract infections.Drug-resistance of pathogenic bacteria to antibiotics is higher.Therefore,we should take precautions to control the urinary tract infections in diabetics.

Objective To investigate the effect of application of video surveillance system for medical staff in the prevention and control of Ebola treatment center (ETC). Methods The high-definition camera installed in the polluted area 100 beds of 24 wards, semi polluted area ring corridor, wear off gowns and other areas without blind spot. Video data and information were collected. The experts of steering group and medical personnel were on duty of video monitoring 24 hours in the medical duty room. They monitored the situation of frontline staff in medical care, whether wearing personal protective equipment (PPE), logistics and transportation problems encountered in the work, and corrected and reminded. Results From December 2015 to January 2014, by checking 182 people on the first-line staff including doctors, nurses and nursing workers, 239 problems of 4 categories were found. The PPE problems was 147 cases (61.50%), while perform operation process issue 35 cases (14.64%), flow logistics distribution problems 31 cases (12.97%), the others 26 cases (10.88%). All the problems were given a timely reminder. There was no infections among medical team. Conclusion Video surveillance system could help medical staff to prevent and control infection, and reduce the risk of infection.

Objective To investigate the role of endoscopic sphincterotomy(EST)and endoscopic nasobiliary drainage(ENBD)in the treatment of non-biliary severe acute pancreatitis(SAP).Methods 73 patients were randomly divided into the endoscopic treatment group(35 cases)and control group(38 cases).The patients in control group received non-surgical treatment.EST plus ENBD were performed in patients in the endoscopic treatment group 72h within hospitalization.Serum levels of amylase before EST and 1d,3 d,7 d after EST were measured;the ease of pain and recovery of bowel function were documented;the mortality rate,complication rate,surgery rote and hospital stay were also observed.Results The successful cannulation rate in the EST group was 94.3%(33/35),and there was no procedure related complication.Serum levels of amylase before EST and 1d,3 d,7 d after EST were(1376±131)U/L,(675±49)U/L,(238±49)U/L,(75±13)U/L,the serum levels of amylase before EST and 1d after EST in the EST group were not significantly different from those in the control group,but the corresponding values at 3 d,7 d were significantly lower than those in the control group(P＜0.01).The apparent effective rate and total effective rate of pain relief was 37.1%and 48.6%.which was significantly higher than those in the control group (26.3%and 28.9%,P＜0.05).There was no mortality in both groups.The complication rate in the EST group within 30 d was 14.3%,which was signiilcanfly higher than that in the control group(44.7%,P＜0.01).The gurgery rate in EST group was 2.86%,which was significantly lower than that in the control group (21.1%,P＜0.05).The hospital stay in EST group was(27.6±4.0)d,which was significantly shorter than that in the control group[(41.7±5.9)d,P＜0.05].Conclusions EST and ENBD treatment for non-biliary SAP was superior to non-surgical treatment within 72 h of symptom onset with excellent safety and feasibility profile.

1263 patients with choledocholithiasis were treated with endoscopic retrograde cholangiopancreatography (ERCP) and endoscopic sphincterotomy (EST) from January 2005 to December 2008, with 1235 (97.8%) cases successfully treated. One-time ERCP removal of the stones was successful in 982 patients, with two times in 129 patients and three times in 124. 1130 patients (89. 5% ) underwent endoscopic nasal biliary drainage (ENBD) after the procedure. 56 patients with refractory stone were treated with intrabiliary plastic stent, among whom 42 were cured through endoscopic retrograde biliary drainage (ERBD) of 1 -3 times. Complications occurred in 29 patients (2. 3% ) with hemorrhage in 8 patients,acute pancreatitis in 17 and perforations in 4. Mortality rate was 0. We concluded that the majority cases of choledocholithiasis can be successfully treated by ERCP, while intrahepatic cholelithiasis and refractory common bile duct stone remained therapeutic challenges. It is also mandatory to evaluate long-term efficacy and complications of ERCP.

Objective To explore the strategies for diagnosis and treatment of anomalous junction of pancreaticobiliary duct (AJPBD) complicated by acute pancreatitis. Methods The clinical dataof 22 patients with abnormal pancreaticobiliary junction were analyzed retrospectively. Results The incidence of acute pancreatitis in this series was 31.8 % (7/22), thereinto, 5 cases(71.4%) in C-Ptype (the common bile duct joining the pancreatic duct) and 2(28.6%) in P-C type (the pancreatic duct joining the common bile duct). Seven patients underwent ERCP+ EST+ ENBD. Two patients with common bile duct stones were treated with stone basket and cholecystectomy was performed in two cases with gallstone. All patients were successfully treated. The follow-up for l year showed that there was no recurrence of pancreatitis. Conclusion Acute pancreatitis usually occurs in patients with AJPBD, especially in C-P type or with gallbladder stone or common bile duct stone. ERCP+EST+ENBD and prophylactic cholecystectomy are effective to prevent and treat acute pancreatitis.

Objective To explore for the methede and effect of endoscopic treatment on biliary leakage and biliary duct damage. Methods All patients with biliary damage such as biliary leakage and biliary duct stricture were treated by endoscopic sphincoterotomy and endoscopic nasobiliary drainage (ENBD) during abdominal cavity drainage ENBD was removd when biliary leakage healed and abdominal cavity drainage ceased for 1～2 weeks were confirmed. Plastic stents were implanted to distend the biliary duct stricture for 2-3 months. Results Twenty-six patients with biliary leakage were cured 3-4 weeks after ENBD. Fourteen out of 17 patients implanted with plastic stent were recovered uneventfully after stent removed, and 4 patients also recovered after installation of double-stents for 3 months, while another case with calculus and stricture of left hepatic duct in spite of implantation of simple-stent suffered repeatedly from biliary tract infection and one case developed hepatic abscess after repeatedly infection for one year before he had the hepatic lobectomy. Conclution Endoscopic therapy is the first choice in treating biliary leakage or secondary duct stricture.
