Objective Isoflurane preconditioning has been shown to protect against cerebral ischemia-reperfusion(I/R)injury.The purpose of this study was to investigate if isoflurane inhalation during reperfusion hasany protective effects.Methods Fourty-two SD rats weighing 318-365 g were randomly divided into 3 groups:sham group(n=6),control group(n=18)and isoflurane group(n=18).Control group and isoflurane groupwere further divided into 10,15 and 20 rain ischernia subgroups(subgroup A,B,C,n=6).In isoflurane group1.4% isoflurane in air was inhaled immediately after reperfusion was started for 30 min.Two days before theexperiment the animals were anesthetized with intraperitoneal chloral hydrate 300 mg?kg~(-1).Microdialysis catheterwas inserter into right hippocampns using stereotactic technique and fixed.BIS microelectrodes were placed in thebrain.Vertebral arteries were permanendy occluded by electric coagulation.Bilateral common carotid arteries wereexposed and atranmatic sutures were placed around them.Globol cerebral ischemia was produced by tighteningcarotid sutures and maintained for 10,15 or 20 min(subgroup A,B,C).Cerebral iscbemia was confirmed by lossof righting reflex,dilated pupils,loss of light reflex,BIS=0 and isoelectric potential on EEG.Carotid sutureswere then released for reperfusion.Isoflurane inhalation was started right after the beginning of reperfusion andmaintained for 30 min.Neurologlc outcome was assessed by motor performance according to Combs(0-10,0=severe dysfunction,10=no dysfunction)at 24 h,48 h and 72 h of reperfusion.Microdialysis samples werecollected before during and 0-15,15-30,30-45 and 45-60 min after ischemia for determination of glutamateconcentration.Three days after ischemia the animals were sacrificed and brains were removed for microscopicexamination of hippocampns CA1 region.The number of apoptotic(TUNEL positive)neurons were counted and thepercentage(the number of TUNEL positive neurons/the total number of neurons)was calculated.Results Theglutamate content in hippocampus was significantly lower in isoflurane group than in control group duringreperfusion(P

Objective To evaluate the effects of occupational therapy and Taoist cognitive psychotherapy on emotional disorder of stroke patients.Methods A total of 136 hemiplegic patients with emotional disorder were randomly divided into a general treatment group,a cognitive psychotherapy group,an occupational therapy group and a combined therapy group(occupational therapy combined Taoist cognitive psychotherapy group).All patients were treated accordingly for 8 weeks and followed up for 6 months.All the patients were evaluated with Fugl-Meyer Assess- ment,COPM and SCL-90.Results It was found that the Fugl-Meyer Assessment and COPM scores were improved gradually in all groups.The combined therapy group scored higher than occupational therapy group(P

To evaluate the efficacy of Yupingfeng droppill and western medicine in treatment of allergic rhinitis, 76 patients from Beijing Shijitan hospital during April 2011 to May 2012 were selected and randomly divided into the treatment group (n = 44) and control group (n = 32). The treatment group was treated with Yupingfeng droppill and cetirizine tablets, the control group was treated with cetirizine tablets, the effect of the two groups was observed after 28 days, after treatment, the symptoms and inferior turbinate volume contrast of the two groups were better than before. The obvious effective rate and total effective rate were 84.09%, 95.45% and 46.87%, 56.25% in the treatment group and and control group. The differences in the obvious effective rate and total effective rate were statistically significant between two groups (P < 0.05), Yupingfeng droppill has the curative effect on allergic rhinitis, which is better than simple oral cetirizine tablets.

Background Eyes with filamentary keratitis present with serious clinical symptoms.This disease is easy to relapse and the treatment is tricky.At present,its pathogenesis is still unclear,and few works were done on filamentous composition.Objective This study was to analyze the composition of corneal filament by imageological and histopathological method,and discuss the formation mechanism of filamentary keratitis.Methods Eighty-eight eyes of 82 cases who suffered from filamentary keratitis were collected in Shandong Eye Hospital between January 2008 and January 2011.The etiologies of the patients were classified and the clinical data were recorded.Firstly,the corneal filiform strip was detected by laser scanning confocal microscopy (LSCM),and the corneal structure was examined by high-definition optical coherence tomography (HD-OCT).Then the composition of filamentary strip was analyzed by Giemsa and Masson trichrome staining of stretched preparation of filiform strip.Results Etiological study showed that filamentary keratitis occurred after penetrating keratoplasty in 40 eyes,after cataract surgery and photorefractive keratectomy (PRK) in 18 eyes,dry eye and neural dystrophic corneal disease in 14 eyes,acute conjunctivitis in 10 eyes.HD-OCT revealed that filament lesion developed to Bowman layer.Filament was composed of epithelial cells,inflammatory cells,mucus and the high reflective strip core with spiral arrangement under the LSCM,and epithelial cells,inflammatory cells and fibrous tissue were seen in the strip core.Giemsa staining exhibited that filament contained corneal epithelial cells,inflammatory cells,mucus and dark blued strip core with helical arrangement.Masson trichrome discovered that the strip core was red fibrous tissue surrounding by blue mucus.Conclusions Epithelial cells,inflammatory cells,mucus and the high reflective strip core with spiral arrangement are the main elements of filament in filamentary keratitis.The lesion can reach Bowman layer.The results contribute to reveal the formation mechanism of corneal filament and assist treatment.

Vascular endothelium plays an important role in regulating vascular homeostasis. Over the past years, it has become clear that endothelial dysfunction is a key event of pathophysiological changes in the initiation and progression of injuries induced by extreme environmental factors. The present review summarizes current understanding of vascular endothelial dysfunction induced by hypoxia, cold and heat, and provides the information for prevention and treatment of environmental exposure injuries.

Objective To discuss human papilloma virus(HPV)prevalence and HPV genotypes distribution and the infection factors,to provide scientific guidance for the prevention and treatment of cervical cancer.Methods From March to November in 2009,605 women received cervical HPV testing in the Tumor Hospital of Harbin Medical University,to obtain specimens of cervical cytology,rapid flow-through hybridization technique (namely Hybribio flow-through hybridization)was used to detect HPV genotypes simultaneously.Single-factor and multivariate factors non-conditional Logistic regression analytic method was used to discuss the relationship between HPV infection of females and age,marital condition,level of education,level of income,occupation,initial age for sex,contraception,number of pregnancies,delivery approach and smoking.Results HPV infection rate was 21.49%(130/605),the positive rate of HPV infection in high-risk subtypes was 15.70%(95/605),the most common type was 5.29%(32/605)in the samples.Single factor non-conditional logistic regression model analysis showed that initial age for sex was the risk factor(X2=4.4618,P<0.05),HPV prevalence increased with a lower initial age for.sex reduced.But there was no significant difference in age,marital condition,education,income,occupation,contraception,number of pregnancy,delivery approach and smoking teams(X2=0.0525,1.8510,1.0348,0.2592,1.1176,1.5664,2.8835,1.4597,2.6161,all P>0.05).The analysis of multivariate factors nonconditional Logistic regression showed that the age of initially having sex,marital status and number of pregnancies were the risk factors(X2=21.6637,8.0574,15.7573,all P<0.05).Conclusions The risk factors for HPV infection are mainly about having sex too young,marital status and number of pregnancies,attention should be paid to screening for HPV.
