Objective:To investigate the effect of allitride injection preconditioning and ischemic preconditioning on renal ischemia/ reperfusion(I/R)injury in rats.Methods:Rat's I/R injury model was established.A total of 75 rats were randomized into five groups(n=15,in each);control group(CON),I/R control group(IR),ischemic preconditioninggroup(IPC),allitride preconditioninggroup(APC),allitride preconditioning and ischemic preconditioning group(AIPC).Kidney tissue and blood specimen were collected from all groups 24 hours after operation.The changes of the renal pathological morphology were observed by hematoxylin-eosine(HE)staining.The levels of serum creatinine(Cr)and urea nitrogen(BUN) were determined.The levels of malonaldehyde(MDA)were determined by thibabituric acid(TBA).The levels of superoxide dismutase(SOD)were determined by xanthine oxidase.Intercellular adhesion molecule-1(ICAM-1)expression in kidney was tested by immunohistoehemistry.Results:IPC or APC group had less necrosis in HE staining than IR group.BUN,Cr,MDA contents in IPC or APC group are less than that in IR group(P

Objective To study the clinical effect of small incision cataract extraction in the treatment of acute angle-closure glaucoma with cataract.Methods Fifty-eight patients with acute angle-closure glaucoma combined with cataract were selected,and according to the digital table they were randomly divided into two groups:control group and observation group.The patients in the control group were treated by conventional method.The patients in the observation group were treated with small incision cataract.The changes of intraocular pressure,anterior chamber depth and visual acuity before and after treatment were observed.The incidence of complications and the satisfaction of treatment were compared between the two groups.Results There were no significant differences in IOP,visual acuity and anterior chamber depth between the two groups before treatment(all P>0.05).After treatment,the intraocular pressure,anterior chamber depth and visual acuity of the observation group were (10.2±4.0)mmHg,(3.3±0.5)mm,(0.85±0.08),respectively,which of the control group were (17.5±5.0)mmHg,(3.2±0.5)mm and (0.50±0.06),respectively.The improvement of intraocular pressure and anterior chamber depth of the observation group was more significant than the control group(t=0.120,0.520,1.012,all P<0.05).The satisfaction rate of the observation group(96.6%) was higher than that of the control group(75.8%)(χ2=9.823,P<0.05).There was no significant difference in the incidence of complications between the two groups(P>0.05).Conclusion Small incision cataract extraction is an effective treatment for acute angle-closure glaucoma complicated with cataract,and the postoperative complications are less.The patients are satisfied with the treatment and deserve to be popularized.

By analysing working flow and layout of imaging department, the importance of scientific planning is elaborated. Also, how to relocate imaging department and facilities rapidly.

Objective To study the methods and therapeutic effect of coverage the soft tissue defect in the foot and ankle with neurocutaneous sural artery island flap.Methods 30 patients had been reconstructed foot and ankle soft-tissue defects with neurocutaneous sural artery island flap,the area of soft tissue defect from 2.0 cm × 3.5 cm～ 8.0 cm× 16.5 cm,the flaps were designed with the size measuring 2.5 cm × 4.0 cm to 8.5 cm × 18cm.Results 26 flaps survived completely and 4 with partial or margin necrosis,the wound infection occurred in 6 patients and were treated with dressing,shin graft and antibiotic drug.Conclusions Sural neurocutaneous island flaps are easy to separate.Major arteries are not injured.It is the ideal flap to repair the soft tissue defect around ankle and foot,the texture,color and contour of the flap is similar to recipient area.

ObjectiveTo prospectively investigate whether any of the perfusion parameters would predict early tumor response to chemotherapy and/or radiotherapy and prognosis in non-small cell lung cancer (NSCLC). MethodsIn a prospective series, Perfusion CT were performed in 152 patients suspected lung cancer with 16-slice or 8-slice multislice CT. Contrast medium (50 ml) was injected at a rate of 4 ml/s with a power injector.The scanning delay was 10 seconds and the scanning time was 50 seconds.Among 152 patients,123 patients were proved lung cancer by pathology.With the perfusion 3.0 software, the parameters including blood flow (BF), blood volume (BV), mean transit time (MTT) and capillary permeability surface area product (PS) were calculated. The perfusion image quality was evaluated on a 4-1eveal scale. The treatment response after chemotherapy and(or) radiotherapy was assessed with Response Evaluation Criteria in Solid Tumors (RECIST) ,and then the relationship between perfusion parameters with early tumor response to chemotherapy and(or) radiotherapy was evaluated. Student t test and Kaplan-Meier estimates were used for data analysis. ResultsIn 84 patients (68.3%), the perfusion image quality was staged level 2 (moderate) and level 3 (good). Among them, 35 patients with NSCLC were assessed with RECIST after chemotherapy and (or) radiotherapy.In these 35 patients, The BF of responders and nonresponders was (81.0±33.6)and (56.3±23.1) ml·min~(-1)·100 g~(-1),respectively, which was significantly different(t=2.393, P=0.023). The median PFS of low-BF group (BF≤80 ml·min~(-1)· 100 g~(-1)) and high-BF group (BF>80 ml·min~(-1)·100 g~(-1)) was 11.8 and 8.0 months respectively (P>0.05), and the median PFS of low-BV group (BF≤6 ml/100 g~(-1)) and high-BV group (BF>6 ml/100 g~(-1)) was 9.2 and 8.0 months respectively(P>0.05), both of them were not significantly different.ConclusionNSCLC in high perfusion are relatively sensitive to chemotherapy and/or radiotherapy, and the response rate is relatively higher, but the progress time is relatively shorter.

respectively)was significantly higher than that for digital anterograde venography (0.684 and 0.587,P =0.026,respectively).Conclusion Diagnostic accuracy and detection rate of residuaI or recurrent varicose veins with CT phlebography are found to be more superior than that with digital anterograde venography which has high guidance value in preoperation and assesses the efficacy of post-surgery treatment.

0.05).Compared with the control group,the weight and viscera coefficient of testis in high dosage group,the sperm counts of epididymides in medium and high dosage experiment groups were all decreased significantly(P0.05).The activities of succinate dehydrogenase(SDH) and nitric oxide synthase(NOS) of testis in high dosage group,the activities of acid phosphatase(ACP),alkaline phosphatase(AKP) and Ca-Mg-ATPase of testis in medium and high doseage groups were all decreased significantly compared with the control group(P

Prevalence of dislipidemia is increasing rapidly in China and there has been a growing interest in Chinese herbal medicine for the treatment of hyperlipidemia both inside and outside China. In this article, lipids regulating effects of 9 herbs or their extracts and 5 herbal formulae which have been published in English-language literature are reviewed. Although evidence from animals and humans consistently supports the therapeutic activities of these Chinese herbal medicines, few multi-center large-scale clinical trials have been conducted to confirm the efficacy and evaluate their safety.
