Objective To explore the protective effect of atorvastatin(Lipitor) on the acute lung injury with ischemia-reperfusion and its possible mechanism.Methods Single lung in site ischemia-reperfusion animal model was used.Thirty Wistar rats were randomly divided into three equal groups and 10 rats were in each group:sham operate group(SO),pulmonary models of ischemia-reperfusion injury(IR) and atorvastation treated group(AT).The two latter groups were all ischemia for 60 minutes followed by reperfusion for 120 minutes.In the AT group,each rat was treated with atorvastation(10mg/kg) for the seventh day.Wet to dry weight rate(W/D),lung permeability index(LPI) were measured respectively.Lung tissue was observed by light microscope.Immunohistochemical technique was used to determine the immunoractivity of nityic oxide synthase(NOS).Results The levels of LPI and W/D were significantly decreased in AT group than in IR group by statistically significant differences(P

Objectives To observe anatomical location of the top branch of plantaris arch which extends from the superficial branch of the medial plantar artery,design and apply flap base on it. Methods On the basis of the anatomical data from 8 feet of 4 fresh cadavers and probed of the Doppler from 50 feet of normal person,defined the anatomic location and body surface projection of the top branch of plantaris arch,a type of new flap design were introduced in the paper. Results The flaps have been used in six cases clinically to treat skin defect of the hand meanwhile,sensation of the flap was regained by suturing nerve.All flaps survived,the appearance of the flaps were excellent,the function of the injured hands were recovered well. Conclusions The design of the flap is reasonable,it is suitable that the free medialis pedis flap of the top branch of plantaris arch is used to repair a small skin defect of the hand.

OBJECTIVE:To observe the efficacy and safety of clopidogrel combined with aspirin in the treatment of transient ischemic attack in the elderly. METHODS:90 elderly patients with transient ischemic were randomly divided into observation group(50 cases)and control group(40 cases). All patients received conventional treatment,statins,low molecular weight dextran and urokinase,etc.,symptomatic treatment was conducted for patients combined with other underlying diseases. Based on it,con-trol group received 100 mg Aspirin enteric-coated tablet,once a day;observation group additionally received 75 mg Clopidogrel bi-sulfate tablet,once a day. No other antiplatelet drugs were allowed. They treatment for 6 months. Clinical efficacy,platelet func-tion indexes(CD63,CD62p)before and after treatment,recurrence rate and incidence of cerebral stroke after 6 months follow-up in 2 groups were observed,and the incidence of adverse reactions was recorded. RESULTS:The total effective rate in observation group was significantly higher than control group,recurrence rate and incidence of cerebral stroke were significantly lower than con-trol group,the differences were statistically significant(P<0.05). After treatment,CD63 and CD62p levels in 2 groups were sig-nificantly lower than before,and observation group was lower than control group,the differences were statistically significant(P<0.05). And there were no obvious adverse reactions during treatment. CONCLUSIONS:Based on conventional treatment,clopido-grel combined with aspirin shows better efficacy than aspirin alone in the treatment of transient ischemic attack in the elderly,it can reduce the incidence of cerebral stroke and recurrence rate,with good safety.

Objective To observe the protective effects with vascular endothelium of Danhong injection for unstable angina (UA)after percutaneous coronary intervention in patients.Methods 180 patients with UA were ran-domly divided into two groups,and patients undergoing percutaneous coronary intervention (PCI)therapy.In addi-tion,90 cases in the control group were treated with conventional western medicine treatment,90 cases in the observa-tion group were treated with conventional western medicine treatment and Danhong injection therapy.The serum super-oxide dismutase (SOD),malondialdehyde (MDA)and brachial artery flow -mediated endothelium -dependent vaso-dilation (FMD),von Willebrand factor (vWF),plasma nitric oxide (NO),endothelin -1 (ET -1)levels and other indicators before and after treatment were detected.Results The total effective rate of the observation group was 96.67%,which was significantly higher than 75.56% of the control group (χ2 =9.23,P <0.05).The endothelial function parameters NO(73.66 ±11.58)μmol/L,ET -1 (64.75 ±6.83)ng/L,vWF(114.58 ±16.24)%,FMD (6.54 ±0.88)% of the observation group after treatment were significantly improved than before treatment (t =8.04,7.90,8.44,7.67,all P <0.05),which of the control group were (62.78 ±10.42)μmol/L,(92.31 ±8.67)ng/L, (152.64 ±18.75)%,(4.18 ±0.72)%,there were significant differences(t =6.78,7.34,7.70,6.56,all P <0.05).The serum SOD (154.62 ±21.37)U /mL and MDA (4.18 ±0.79)nmol/L levels of the observation group were significantly improved than before treatment(t =7.58,8.67,all P <0.05 ),which of the control group were (132.45 ±26.89)U /mL,(5.27 ±1.16)nmol/L,there were significant differences (t =7.22,7.81,all P <0.05). Conclusion Danhong injection for the treatment of UA stasis syndrome can be widely promoted by reducing oxidative stress on vascular endothelial damage,and improving endothelial function in patients after PCI,has great clinical value.

Objective To study the feature of the etiology of pediatric syncope by cases study,and to discuss the feasibility on identification between the cardiac and neurally-mediated syncope with its inducements and symptoms.Methods One hundred and eleven patients were etiologically classified by standard diagnostic procedure to summarize the inducements,presymptoms and symptoms.The data about cardiac and neurally-mediated syncope were statistically treated to find their characteristic manifestation.Results Among these,60.4% was non-cardiovascular syncope,18.9% was postural hypotension,18.0% was vasovagal syncope and 9% was cardiac syncope.Most of them were non-cardiac syncope and neurally-mediated syncope was on the top,while cardiac syncope was rare in children.Prolonged standing and nausea was the feature of the neurally-mediated syncope,and the cardiac syncope is associated with physical exercise.Conclusions Most pediatric inpatients were non-cardiovascular syncope in which neurally-mediated syncope is first on the list.The movement-related syncope is the feature of the cardiac syncope.The prolonged standing and nausea are due to neurally-mediated syncope.

Phage display is a widely used gene engineering high technology.Through the display of exogenous peptides or proteins fused specific coat protein on the surface of phages,it is possible to construct proteins or peptides libraries and screen interesting proteins,peptides and antibodies successfully.Most commonly used phage display technology is phagemid/helper phage system,in which helper phages are essential for the replication and assembly of phagemid particles.In this review,in combination with the newest research dynamic status,we summarize phagemid/helper phage double-genome system.We mainly emphasized the features and mutation mechanisms of different helper phages.We also made some prospects for the future directions,in the meanwhile,we also expect that our experience can provide some help for further maturity of the technology.
