Objective To evaluate the application effect of clinical pathways (CP) in children with bronchopneumonia.Methods The literature of randomized controlled trials (RCTs) in children with bronchopneumonia were retrieved by searching PubMed,Cochrane Library,Web of Knowledge,Wanfang database,VIP,and CNKI from their inception date to March 2014.Meta-analysis was performed by Revman 5.2software.Results Six RCTs involving 24 559 patients were finally selected,with 12 269 cases in the CP group and 12 290 cases in the traditional treatment group.The results of Meta-analysis showed that there were significant differences between the CP group and the traditional treatment group in the cure rate [OR =1.67,95 % CI (1.03,2.77),P =0.04],length of hospital stay [MD =-1.21,95 % CI (-1.95,-0.48),P =0.001],hospitalization expenses [SMD =-3.68,95 % CI (-5.04,-2.32),P < 0.000 1],days of antibiotic using [MD =-1.20,95 % CI (-1.51,-0.89),P < 0.000 01] and patient satisfaction [OR =6.12,95 % CI(3.12,12.04),P < 0.000 01].Conclusion CP is superior compared with the traditional treatment for bronchopneumonia,and is worthy of spread in clinical.

Aim To investigate the relationship between GABAA receptor or NMDA receptor and the amnestic effect induced by etomidate.Methods Amnestic model was established by intraperitoneal injection of etomidate(3 mg?kg-1) in mice before intracerebroventricular injection of different doses of bicuculline or NMDA,then the error times,step down latency and step through latency were observed and recorded in the step down test and step through test.Results Bicuculline(2,4 ?g) instead of NMDA by intracerebroventricular injection could decrease the error times and increase the step down latency and step through latency of amnestic mice in the step down test and step through test.Conclusion GABAA receptor rather than NMDA receptor may be an important target for the amnestic effect induced by etomidate.

Aim To observe the effects of ketamine on Na+,K+-ATPase,Ca2+-ATPase and NOSase activity in different cerebral cortex in convulsive mice.Methods The mice were randomly divided into blank group,normal saline(NS) group and ketamine 25 mg?kg-1 (KetⅠ),50 mg?kg-1(KetⅡ) group. The animals of blank group were killed directly.Convulsion was induced by intraperitoneally(ip) strychnine(1.5 mg?kg-1) in other groups,and correspond drugs were administered ip before five minutes.Action variety of mice was observed. Animals were killed on 30 minutes after strychnine injection.The activity of Na+,K+-ATPase,Ca2+-ATPase,TNOSase and iNOSase were assessed by spestrophotometric analysis in different cere-bral cortex(forehead,parietal and occipital area).Results Ketamine group could decrease mortality completely. The duration of tonic state in KetⅡ group was significantly shorter than that in KetⅠgroup.Compared with blank group,Na+,K+-ATPase and Ca2+-ATP ase activities were decreased in the group of NS and KetⅠ,and recovered normal level in the group of KetⅡ at parietal and occipital area. TNOS ase activity was decreased by 1/3 in KetⅡ group(P

Aim To investigate the relationship between amnestic effect of enflurane or isoflurane and NMDA receptor.Methods Amnestic model was established by intraperitoneal injection of enflurane(0.4 ml?kg-1)or isoflurane(0.3 ml?kg-1)respectively in mice before intracerebroventricular injection of different doses of NMDA(25,50,75 ng),then the error times,step down latency and step through latency were observed in the step down test and step through test.Results NMDA(50,75 ng)by intracerebroventricular injection could decrease the error times,and increase the step down latency and step through latency of amnestic mice induced by enflurane or isoflurane in the step down test and step through test.Conclusions NMDA by intracerebroventricular injection can improve amnestic effect of enflurane or isoflurane partially.NMDA receptor may be an important target for amnestic effect of enflurane or isoflurane.

Objective To investigate the relation of autophagy and postherpetic neuralgia in elderly patients,and provide new methods for prevention and treatment of postherpetic neuralgia.Methods One hundred thirty-five specimens were obtained from elderly patients with herpes zoster,containing 83 patients with herpes zoster plus neuralgia and 52 cases with non-neuralgia herpes zoster.The level of autophagy was determined by acridine orange-stain.The protein expressions of autophagy marker protein LC3 and autophagy related protein Beclinl were detected by Western blot.Results Flow cytometer detection after acridine orange-stain showed that mean fluorescence intensity (MFI) of herpes zoster plus neuralgia patients was 0.775±0.068 and non-neuralgia herpes zoster patients was 0.342±0.025.The level of autophagy of non-neuralgia herpes zoster patients was significant lower than herpes zoster plus neuralgia patients (P<0.05).The expressions of autophagy marker protein LC3 and autophagy related protein Beclin1 detected by Western blot also showed the level of autophagy of non-neuralgia herpes zoster patients was decreased compared with herpes zoster plus neuralgia patients.Conclusions High level autophagy is risk factor for postherpetic neuralgia in elderly patients.

Objective To investigate the influence of self-management and education on behaviors of medical compliance of patients undergoing vitrectomy combined with tamponade.Methods Sixty-four patients undergoing vitrectomy combined with tamponade were randomized equally into the control group and observation group in the order of admission.The control group received routine care and health education,while the observation group received self-management education follow-ups besides the routine nursing.The two groups were compared in terms of the cumulative time of the correct position,compliance behavior and the incidence of postoperative complications.Results The cumulative time of the correct position of observation group was longer than that of the control group after operation.The observation group did better in compliance behavior than the control group and the incidence of postoperative complications in the former group was lower than the latter(P<0.05).Conclusion Self-management and education can enhance patients’behaviors in medical compliance and decrease postoperative complications and promote the success of the surgery.

Objective To investigate the clinical value of serum homocysteine (Hcy),Cystatin C (CysC) detection in coronary heart disease prevention,diagnosis and treatment.Methods A total of 200 cases of coronary heart disease patients including 50 cases of acute myocardiac infarction (AMI) (AMI group),85 cases of unstable angina pectoris (UAP)(UAP group.) and 65 cases of stable angina pectoris (SAP) (SAP group) were selected,and 120 cases of healthy controls were selected as control group.The serum levels of Hcy and CysC were detected and compared.Results The serum levels of Hcy and CysC in AMI group,UAP group and SAP group were significandy higher than those in control group[Hcy:(22.35 ± 8.18),(16.54±7.56),(14.52±6.38) μmol/Lvs.(9.35±3.23) μmol/L; CysC:(1.32±0.27),(1.88± 0.66),(1.19 ± 0.46) mg/L vs.(0.80 ± 0.33) mg/L],and there were significant differences between two groups (P< 0.01).The serum level of Hcy in AMI group was higher than that in UAP group and SAP group [(22.35 ± 8.18) μ mol/L vs.(16.54 ± 7.56),(14.52 ± 6.38) μ mol/L],and there was significant difference (P < 0.01).Conclusions The relationship between Hcy,CysC level and coronary heart disease is close,and Hcy levels increase with increasing degree of coronary heart disease.Detection of Hcy and CysC has some clinical value on prevention,diagnosis,treatment of coronary heart disease.
