OBJECTIVE:To observe clinical efficacy and safety of alprostadil combined with salvia ligustrazine in the treat-ment of aged patrents with unstable angina pectoris. METHODS:A total of 150 patients with unstable angina pectoris department of our hospital during Oct. 2011-Mar. 2015 were randomly divided into alprostadil group,salvia ligustrazine group and combination group according to random number table,with 50 cases in each group. Three groups received routine treatment. Alprostadil group additionally received Alprostadil injection 100 μg added into 0.9％ Sodium chloride injection 250 mL,ivgtt,qd,on the basis of routine treatment. Salvia ligustrazine group additionally received Salvia ligustrazine injection 10 mL added into 0.9％ Sodium chlo-ride injection 250 mL,ivgtt,qd,on the basis of routine treatment. Combination group additionally received constant dose of Al-prostadil injection and Salvia ligustrazine injection. Hemorheological indexes (high shear whole blood viscosity,low shear whole blood viscosity,plasma viscosity,hematocrit,fibrinogen),cardiac function indexes(LVEF,SV,LVEFD,LVST),serum CRP, NO,ET,SOD and clinical efficacies were observed in 2 groups before and after treatment;the occurrence of ADR was compared between 2 groups. RESULTS:Before treatment,there was no statistical significance in hemorheological indexes,cardiac function indexes or serum CRP,NO,ET,SOD level between 2 groups (P>0.05). After treatment,plasma viscosity,the whole blood high and low shear viscosity,hematocrit,fibrinogen,serum CRP and ET levels of 3 groups were decreased significantly,while LVEF,SV,serum levels of NO and SOD were increased significantly,combination group was significantly better than alprostadil group and salvia ligustrazine group,with statistical significance (P<0.05). There was no statistical significance in above indexes between alprostadil group and salvia ligustrazine group (P<0.05). Total response rate of combination group was 90.00％,which was significantly higher than 74.00％of alprostadil group and 72.00％of salvia ligustrazine group,with statistical significance(P<0.05). There was no statistical significance in the incidence of ADR between 2 groups (P>0.05). CONCLUSIONS:Alprostadil combined with salvia ligustrazine can effectively reduce the blood viscosity of patients with unstable angina pectoris,improve cardi-ac function and endothelial function,reduce myocardial ischemia injury and show significant therapeutic efficacy and safety without increasing the incidence of ADR.

Objective To explore the method of repairing wound defects with exposed tibia. Methods 32 patients with soft tissue defects with exposed tibia were treated with three kinds of flaps pedicled with interior,lateral and posterior vascular perforating branches in the leg,respectively.Re- suits One flap with distal part necrotic was treated with change of dressings and got one-stage healing. One case had delayed union for muscular infection under the flap.Other flaps all were successful and sur- vived.No ostemyelitis was found.Conclusion The flap pedicled with vascular perforating branches of leg has abundant blood supply and is a good method for repairing small or middle wound defect with ex- posed tibia.

We compared the RT-LAMP,LAMP and L-J for detecting MTB to provide the rapid diagnosis method for tu-berculosis.In this assay,NTM and other common respiratory bacteria were used to detect specificity,Mycobacterium tubercu-losis specific products were identified by restriction enzyme digestion.To detect sensitivity,we used RT-LAMP,LAMP and L-J to detect 100 cases sputum specimens from patients with tuberculosis and 22 cases control sputum specimens,the 10 times dilution of 1 ng/μL H37Rv standard strains was used to detect RT-LAMP limit.The results showed that the positive rate of RT-LAMP,LAMP and L-J were 100%,92%,88%.RT-LAMP and L-J,RT-LAMP and LAMP were statistically signifi-cant,RT-LAMP had 10 times higher sensitivity than LAMP,RT-LAMP not only to identify viable but also capable of detec-ting a single copy of MTB.So RT-LAMP is superior to LAMP and L-J and is practical for use in primary medical care institu-tion or peripheral laboratory.

Objective To explore surgical treatment of gliomas involving the motor eloquent area. Methods Twelve cases of gliomas involving precentral gyrus were underwent awake surgery procedures assis- ted with neuronavigation and brain functional mapping by cortical electrical stimulation.Results Eleven ca- ses acquired accurate location of both lesions and eloquent areas by neuronavigation and direct cortical stimula- tion.7 cases of motor cortices and 2 cases of motor speech centers were confirmed during the operation.Re- section,verified by postoperative MRI,was total in 8 cases (66.7%) and subtotal in 4 patients.Histological examination revealed an infiltrative glioma in all cases (8 low grade astrocytomas,2 high grade astrocytomas and 2 glioblastoma).Four patients had no postoperative deficit,while the other 8 patients were impaired, with,in all cases except one,complete recovery in 7 days to one month.Conclusion Direct cortical elec- trical stimulations and awake surgery offer a reliable,precise and safe method,allowing functional mapping es- pecially useful in case of infiltrative cerebral tumors in eloquent areas.This technique allows improvement in the quality of tumoral resection and concurrently a minimization of the risk of definitive postoperative neurologi- cal deficit.

Objective To explore the magnetic resonance spectroscopy characteristics of prefrontal white matter and lenticular nucleus in patients with bipolar Ⅱ disorders.Methods Thirty patients with bipolar Ⅱ disorders and 20 healthy controls,collected in our hospital from September 2012 to April 2013,were evaluated with Multi-Voxel 1H-MRS scans on prefrontal white matter and lenticular nucleus to assess the levels of N-acetyl aspartate (NAA),choline compound (Cho),creatine (Cr) and myo-inositol (mI),and then,the ratios of NAA/Cr,Cho/Cr,mI/Cr,NAA/Cho and NAA/Cho+Cr were calculated.Results Levels ofNAA,NAA/Cr,Cho and mI in the right prefrontal white matter were significantly lower in patient group than those in the normal controls (P＜0.05); NAA level,and ratios of NAA/Cr,NAA/Cho,NAA/Cho+Cr in the left prefrontal white matter were obviously lower in patient group than those in the normal controls (P＜0.05); NAA and Cho in right lenticular nucleus were lower as compared with those in the healthy control subjects (P＜0.05).Conclusion Prefrontal white matter fiber damage and glial cell disfunction occur in patients with bipolar Ⅱ disorder; besides,neuronal loss and disfunction in the right lenticular nucleus exist.

OBJECTIVETo study the molecular characteristics of Noroviruses causing outbreaks of acute gastroenteritis in Huzhou.

METHODSFrom 2008 to 2010, total 119 fecal specimens collected from outbreaks of acute gastroenteritis were tested for Norovirus. Partial sequence of RNA dependent RNA polymerase (RdRp) of the positive samples were amplified by RT-PCR, then the PCR production were purified, sequenced and put into phylogenetic analysis.

RESULTS50 of 119 specimens were positive for Norovirus by real-time RT-PCR. Out of those 50 Norovirus positive specimens, 9 were Norovirus Genogroup I (GI) positive, 35 were Norovirus Genogroup II (GII) positive, 6 was both Norovirus GI and GII positive. 12 PCR products for RdRp were selected for further studies on sequencing. Phylogenetic analysis revealed that the 5 GI norovirus isolates were belonged to genotype GI/2 and GI/3. Of the 7 GII norovirus isolates, 6 were belonged to genotype GII/4, 1 was belonged to genotype Glib.

CONCLUSIONNorovirus is a major cause of outbreaks of acute gastroenteritis in Huzhou and the epidemic strains of norovirus isolated from Huzhou had a high degree of genetic diversity.

OBJECTIVETo explore the effects of antisense epidermal growth factor receptor (EGF-R) oligodeoxynucleotides on ultraviolet-induced c-jun activity of keratinocytes after EGF-R oligodeoxynucleotides transfect to HaCaT in vitro.

METHODSc-jun DNA binding activity after ultraviolet-B (UVB) irradiation and EGF-R oligodeoxynucleotides transfection were determined with a highly sensitive and specific colorimetric method. After EGF-R oligodeoxynucleotides transfection, the mRNA level of EGF-R was detected by reverse transcription polymerase chain reaction method.

RESULTSCompared with control groups, c-jun activity increased significantly in UVB (10, 20, 30 mJ/cm2) irradiation groups (P < 0.05). EGF-R mRNA and c-jun activities induced by UVB were inhibited after the keratinocytes were transfected with EGF-R antisense oligodeoxynucleotides at 2, 4 and 8 microg/ml concentrations (P < 0.01).

CONCLUSIONThe ultraviolet-induced c-jun activity of keratinocytes can be mediated by EGF-R and inhibited by EGF-R antisense oligodeoxynucleotides, which is transfected to keratinocytes and mediated by lipofectamine.
