Objective To evaluate the efficacy of endoscopic mucosal resection (EMR) for sub-pedicle or non gastrointestinal tract polyps in primary hospital.Methods Retrospectively analyzed the data of 43 patients of EMR from November 2011 to December 2013.Results In 43 patients,84 lesions were resected,2 cases of hemorrhage during EMR immediately,1 case delaying hemorrhage,no complications such as perforation or infection occurred.Length of operation time was (6.73 ± 1.24) min per focus,hospital stay was (5.50 ± 0.61) d,there was no recurrence in any patient by endoscope during a follow-up of 6-24 months.Conclusions The technique of EMR is simple,less trauma,no pain,fast recovery for patients.As long as selecting suitable patient,EMR can be carried out widely in primary hospital.

Objective To review the clinical experiences of Kugel herniorrhaphy.Methods Fifty-eight patients with sixty-two groin hernia were performed with Kugel patch.Results Mean operating time was 25min.The patients could walk in fifty hours and work in five days after operation,respectively.No recurrence or discomfort was found during a fellow-up of 1～36 months.Conclusions Kugel herniorrhaphy is a minimally invasive,tension-free,almost sutureless,and total inguinal repair.The leaning curve is about 10 Kugel herniorrhaphy.

0.05). The LDH was lower ,and cell viability was higher in group IPC than those in control group. The LDH was higher ,and cell viability was lower in grou p SMT, group NS 398 and group SB than those in group IPC. CONCLUSIONS: In late p hase of preconditioning ,the p38MAPK activity and expression of iNOS and COX 2 increase significantly in rat cardiomyocytes, activited p38MAPK mediates iNOS ,then promotes COX 2 expression.

Objective To investigate the application and nursing care of bronchoalveolar lavage (BAL)by fiberoptic bronchoscopy in patients with mechanical ventilation. Methods 64 patients with mechanical ventilation in RICU were randomly divided into the control group and the observation group with 32 patients in each group. The patients in both groups were accepted anti-infection, atomization inhalation and other supportive treatments. The patients in the observation group were treated with BAL, and the patients in the control group accepted routine treatment. The therapeutic effects in the two groups were evaluated and compared. Results There was significant difference in the recovery rate and effective rate, the blood gas analysis compared with the control group was significantly improved, the time of pulmonary infection control window, mechanical ventilation, length of stay were shorter than the control group. The case number to remove ventilator successfully, organs failure and hospital mortality were less than the control group. Conclusions Fiberoptic bronchoscopy with BAL treatment could be safety and efficacy for patients with mechanical ventilation. Nursing intervention plays an important role and a good therapeutic effect for improving achievement ratio of BAL.

Objective To evaluate the effect of health education combined with lung function test on smoking cessation in smoking sanitation workers. Methods Sixty-nine sanitation workers who smoke were divided into two groups by using the table of random number, routine group (n=35) and lung function test group (n=34). The routine group was given health education. According to the lung function, those in the lung function test group were divided into normal lung function group (19 cases) and abnomal lung function group (15 cases) who received both health education and lung function test. Success rate of smoking cessation and the relapse rate were compared at 2 and 6 months follow-up. Results At 2 and 6 months follow-up, the smoking cessation rates of routine group were [10(29%), 4(11%)], which were lower than those of the normal lung function group [7(37%), 3(16%)], the differences were not statistically significant (P>0.05). The smoking cessation rates of routine group were lower than those in abnormal lung function group[11 (73%), 10(67%)] (P<0.05). The smoking cessation rates of the normal lung function group were significantly lower than those of abnormal lung function group (P<0.05). The relapse rate of routine group[6(17%) and the normal lung function group[4(21%)]at 6 months follow-up were not significantly different. The relapse rate of the normal lung function group and that of abnormal lung function group were not significantly different. Conclusion Health education combined with lung function test could help smokers with abnormal lung function to give up smoking successfully.

Objective To investigate the effect of extracts from Periplaneta americana L.on reversing MDR in HepG2/ADM.Methods HepG2/ADM was induced by continuous stepwise exposer to ADM.To investigate the effect of extractive from Periplaneta americana L.on drug resistance-associated protein( P-gp、MRP、LRP和BCRP) by immunocytochemical method and RT-PCR method.Results HepG2/ADM cells to ADM shows a strong multiple drug resistance that is 10.4 times,For DDP,5-FU showed weak resistance.The extractive from Periplaneta americana L.can cut the expression of P-gp and MRP1 protein in HepG2/ADM from immunocytochemical method,and it has statistically significant.The extractive from Periplaneta americana L.can cut the expression of P-gp gene,and it has statistically significant.Conclusion The extract from Periplaneta americana L.can effectively reverse MDR in HepG2/ADM,which targets for P-gp and MRP1 protein and P-gp gene of HepG2/ADM cells.

Objective The aim of this study was to demonstrate the effectiveness of the procedure for the prolapse and haemorrhoids in management of haemorrhodis.Methods Analyze the data of sixty-two consecutive patients with third or fourth degree hameorrhoids treated by the procedure for the prolapse and haemorrhoids.Results The median surgical time was 15 minutes,the median postoperative hospital stay was 2.3 days,median time to retum to normal activity was 6.8 days.Five patients need postoperative analgesic,on postoperative bleeding,eighteen patients had acute urinary retention.Fifty-six(90.32%) of the patinets had been followed up to 6 weeks,fifty patients were satisfied with the results of the procedure.Conclusion The procedure for the prolapse and haemorrhoids is a safe and effective treatment for severe haemorrhoids and with the advantages of shorter time of operation and inpatient stay,earlier return to normal activity.

AIM: To determine the contents of hesperidin and salvianolic acid B in Xiaopikang Capsule(Folium Citri reticulatae,Radix et Rhizoma Salviae miltiorrhizae,etc.) by HPLC. METHODS: The HPLC system consisted of Diamonsil C_(18) column(250 mm?4.6 mm,5 ?m), metanol-acetonitrile-formicacid-water(30∶10∶1∶59) mixture as mobile phase,detection wavelength at 284 nm,flow rate of 1.0 mL/min. RESULTS: The ca-(libration) curves of two ingredients were linear within the ranges of 0.22 ?g-2.2 ?g(r=0.999 6,hesperidin),(1.62 ?g-10.2 ?g)(r=0.999 9,salvianolic acid B),respectively.The average recoveries of hesperidin was(98.9%)(RSD=1.60%),salvianolic acid B for 99.02%(RSD=0.97%). CONCLUSION: The method is rapid,sensitive and accurate.
