OBJECTIVE To prevent clinical infection due to intravenous infusion by indwelling trocar.METHODS The methods of intravenous infusion by indwelling trocar,the location the indwelling time and the relationship of veinal infection with indwelling trocar were observed in 320 cases.RESULTS Veinal infection didn′t occur in patients who used the trocar.CONCLUSIONS The risk factors of infection due to intravenous infusion by indwelling trocar include the location of puncture,washing hands,aseptic technique,enveloping duct technique,application exchange,osmotic pressure of drug,indwelling time,operation technique,patients′ own situation and so on.Correct operation and standard management can prevent infection of intravenous infusion by inewelling trocar.

OBJECTIVE To enhance the control of nosocomial infection and the quality of medical nursing.METHODS The risk factors and etiological factors of nosocomial infection caused by non-medical-staff in sickroom were analyzed.RESULTS In order to control the nosocomial infection,we needed to strengthen the management in the following aspects: working procedures and tools of non-medical-staff,knowledge and sterilizing procedures for visitors,etc.CONCLUSIONS Standardized monitoring to non-medical-staff is the important measure to reduce the nosocomial infection.

To explore the rational nursing care in patients with acute aortic saddle embolism perioperatively.Emergency operations of retrograde catheter or transaortic embolectomy were done on 36 cases,and intensive care was given simultaneously.The results showed the normal blood flow was restored right after operation.3 patients died of myonephropathic metabolic syndrome or heart failure.30 cases were followed up from 1 to 4 years.A good result was obtained in 20 cases.The results indicated that a higher cure rate, with less complications and lower mortality rate,could be obtained if operative measures were untaken early and perioperafive nursing care were stressed,in acute aortic saddle embolism.

OBJECTIVE To prevent intravenous transfusion infection through scalp acupuncture.METHODS The method,site,time and the infection rate of 380 cases with scalp acupuncture were analyzed.RESULTS No infection was occurred in 380 scalp acupunture cases.Among them,36(6.8%) cases were found phlebitis due to more times puncture and irritation of exosmosis medicine.CONCLUSIONS It is important for nurses to choose intravenous and prepare medicine correctly.Normal procedure and management of scalp acupuncture can prevent intravenous infection.

OBJECTIVE To enhance the control of nosocomial infection and improve the quality of medical nursing. METHODS The risk factors and etiological factors of nosocomial infection in sickroom were analyzed. RESULTS In order to control the nosocomial infection we needed to strength the disinfection management in the following aspects: air in the ward,nursing procedures,implements and hands of doctors and nurses. CONCLUSIONS Strict sterilizing procedures and standardized monitoring are the important measures to reduce the nosocomial infection.

OBJECTIVE To prevent the infection at intravenous injection site with peripherally inserted central catheter(PICC). METHODS The relationship between infection with sites,methods,and times of PICC placement in 160 patients was observed. RESULTS There was no correlated infection in all the patients,but family nursing might lead to infection. CONCLUSIONS Regular management and standard operation can prevent infection.Instructions of family nursing and follow-up are necessary for infection control.

Objective To study and analyze the therapeutic effect of Oza Grey Na (continuous micro pump infusion) on cerebral infarction. Methods 100 patients with cerebral infarction treated in our hospital from February 2015 to August 2016 were selected and randomly divided into the control group and the experimental group, with 50 patients in each group. The patients in the control group received routine treatment, while the experimental group received Oza Grey Na (continuous micro pump) treatment, intravenous drip, 1 courses for 2 weeks. The liver and kidney function, coagulation function, blood routine and other indexes of the patients in the experimental group and the control group were examined before and after treatment, and the therapeutic effects of the two groups were compared and analyzed. Results After treatment, 50 patients in the experimental group were invalid, 3 cases were effective, 20 cases were markedly effective, and the total effective number was 47 cases in 27 cases. Patients in the control group, 8 patients were invalid, 18 patients were effective, 24 patients were markedly effective, and the total effective number was 42 cases. The effective rate of the treatment group was 94％, and the effective rate of the control group was 84％, which was lower than that of the experimental group (P<0.05). There were no severe complications in the experimental group and the control group, and there was no significant difference in the incidence of complications between the 2 groups, and there was no statistical significance. Conclusion Oza Grey Na (continuous micro pump) treatment of cerebral infarction clinical effect is better, more efficient, with further clinical promotion and application of significance.

Objective To elucidate the effects of thalidomide on the expressions of basic fibroblast growth factor(bFGF) in parental and cisplatin resistant human lung adenocarcinoma cell line A 549 and A 549 DDP Methods RT PCR and lmmunohistochemistry were used to detect the bFGF mRNA and protein expression in A 549 and A 549 DDP Results bFGF mRNA expression levels and protein expressions in A 549 and A 549 DDP were all significant reduced after treatment of thalidomide (6 ?g/ml)(all P

Objective To investigate the expression difference of multidrug resistance and apoptosis related genes and its contribution to mechanisms of multidrug resistance in human lung adenocarcinoma parental cell line A 549 and cisplatin resistant cell line A 549 DDP Methods RT PCR and Immunohistochemical staining were performed to detect the mRNA expressions and protein production of multidrug resistance related protein (MRP),lung resistance protein (LRP),bcl 2,and C erbB 2 in A 549 and A 549 DDP .Results MRP,bcl 2,and C erbB 2 mRNA were expressed in A 549 ,but no LRP mRNA was detected in A 549 MRP,C erbB 2,and LRP mRNA expression levels in A 549 DDP were significant higher than those in A 549 ,otherwise,LRP mRNA was detected in A 549 DDP There was no difference of bcl 2 mRNA expressions between A 549 and A 549 DDP ( P =0 731) Bcl 2 protein expressions were strongly positive both in A 549 and in A 549 DDP MRP protein expressions in A 549 were faint positive,while C erbB 2 and LRP were negative MRP protein expressions in A 549 DDP was median positive C erbB 2 and LRP protein expressions in A 549 DDP were strongly positive Conclusions The heterogenous expression of MRP,C erbB 2,and LRP in A 549 and A 549 DDP may be associated with primary and secondary drug resistance in lung cancer
