Objective:To explore protective mechanism of buflomedil Hydrochloride on the neuron of damaged Sciatic nerve in rats. Methods:SD rats were divided into normal, model,buflomedil hydrochloride group in random. Preconditioned for 14 days,the sciatic nerve lesion models were performed, the Bcl-2 and Bax positive cells were counted by immmunohistochemistry at the end of 6h,12h,24h,48h,72h,96h,7days respectively. Results:(1) At the end of 12h after the model perfomed,The expressions of Bcl-2 in buflomedil hydrochloride group increased obvionsly than the normal and model groups,peaked at 24~48h,and at the end of 7days,the expressions of Bcl-2 in buflomedil hydrochloride group increased obviously compared with model group.(2)The expressions of Bax in buflomedil hydrochloride groug were lower than the normal and model groups in the same periods,and that was the lowest at the end of 7 days,It was different significantly than that of model group(P

OBJECTIVE: To observe the effects of long-term administration of pioglitazone at different doses on the expression of glucose transporter-4(GLUT-4) of cardiac muscle tissue in rats and to discuss the possible mechanisms.METHODS: A total of 40 Wistar rats were enrolled,of which,10 were randomly assigned to normal control group(NC),and the other 30 were injected intraperitoneally with streptozotocin to establish diabetes mellitus(DM) rat model.After successful modeling,the rats were assigned to DM model group(DM,normal saline),high and low dose pioglitazone group(HP,LP;0.75,0.25 mg?kg-1?d-1).The NC groups received normal saline for 12 weeks.Blood glucose(BG) level before grouping(baseline level) and prior to death was determined by tail-cutting method.GLUT-4 level in cardiac muscle tissue and both protein and mRNA expression of AMPK? were determined by RT-PCR and western blot,respectively.RESULTS: As compared with NC group,the BG level in DM group was significantly increased but the expression of GLUT-4 and AMPK? decreased significantly(P

Objective To comparatively analyze the results of the PT derivative method and the Clauss method for detecting fi-brinogen(Fib) by the automated coagulation analyzer and to explore their accuracy and clinical value .Methods Fib was detected in 156 blood samples selected from the patients in this hospital from March to May 2013 ,25 normal control samples and 13 positive samples of D-dimer (DD) by the TP derivative method and the Clauss method .Results The Clauss method and the PT derivative method by Sysmex CA-1500 coagulation analyzer had good repetitive rate in measuring Fib for 25 times ;when Fib<1 .0 g/L ,the results detected by these two methods had statistically significant difference (P<0 .05);when Fib in the range of 1 .0 -2 .0 g/L , 2 .1-3 .0 g/L ,3 .1-4 .0 g/L ,the detection results had no statistically significant difference between the two methods (P>0 .05);when Fib in the range of 4 .1 -5 .0 g/L ,the detection results had statistically significant difference (P<0 .05);when Fib>5 .0 g/L ,the detection results had statistically significant difference (P<0 .05);in 13 DD positive samples ,the detection results of the PT derivative method were significantly higher than those of the Clauss method with statistically significant difference (t=8 .530 , P<0 .05) .Conclusion The difference exists between the PT derivative method and the Clauss method for detecting Fib ,but the ac-curacy of the Clauss method is higher than its specificity ,the Clauss method should be the first choice for the clinical determination of plasma Fib .

Objective:To analyze the reasons of complicated arrhythmia after resection of lung. Methods:The relation of arrhythmia with age, operation mode,preoperative lung function and postoperative blood gas of 562 cases of lung resection were analyzed. Results:There were 104 of 562 cases (18.5%) complicated with arrhythmia postoperatively. 38.77% of them were older than 70 years. 27.72% had operation of pneumonectomy.The parameters of FEV 1,MVV,FVC lower than 50% were 67.24%,46.53% and 67.93% respectively.Postoperative blood gas analysis of the 23 cases showed that Po 2 was lower than 60 mmHg,Pco 2 was higher than 45 mmHg,So 2 was lower than 96%.21 of them developed postoperative arrhythmia.After tracheotomy and immediately correcting anoxia,all the 21 patients recovered from arrhythmia within 3 days.4 patients died in this group(3.84%).Conclusion:Pneumonectomy,in patients older than 70,results in the parameters of FEV 1,MVV and FVC lower than 50%.Significant anoxia is the cause of arrhythmia.

Objective:To discuss the method of Video Assisted Thoracoscopy(VATS) in diagnosis and treatment of small peripheral lung neoplasm.Methods:A wedge-shaped excision with VATS had been performed on 20 patients with small peripheral lung neoplasm.The sample had been sent to pathology during surgery.Lobectomy was done with the malignant tumor.Results:14 cases(70%) were malignant in stage IA ,6 cases were benign.The mean follow-up time postoperatively was 24 months(12～36months),there was no relapse case.Conclusion:For those patients,the diameter of neoplasm is smaller than 15mm,and antibiotic treatment is ineffective for 2～3 weeks,VATS can be available for diagnosis and treatment.

Objective To establish a Chromatin immunoprecipitation assay to analyze transcriptional regulation of gene expression in hepatocytes. Methods The PEPCK gene was used as a target gene, HPRT, MBP and IgG were used as internal reference, the chromatin immunoprecipitation and PCR were performed with antibody specific for CREB to verify bindings of transcription factor CREB to the PEPCK promoter under various metabolic conditions. Results Transcription factor CREB occupies its target sites in the PEPCK promoter and this binding is increased by 4-fold during fasting in the anti-CREB antibody immunoprecipitated DNA fragments. Conclusion The results confirm that CREB binds to the PEPCK promoter and is involved in transcriptional regulation of PEPCK gene in hepatocytes.

Objeetive To investigate the clinical effects and nursing interventions of endoscopic sphincterotomy(EST)for treating elderly patients with choledocholithiasis.Methods The clinical data of 73 cases of patients operated by EST were retrospectively analyzed.Before surgery the psychological nursing,examination and preparation were meticulously performed,the changes of vital signs and nursing were closely observed during surgery,the respiratory tract nursing,cardiovascular disease and diabetes nursing,pain nursing and complications treatment were performed after surgery.Results There were 69cases of 73 patients were successful,the success rate was 94.5%;8 cases of concurrent hyperamylasemia were given conservative treatment and had clinical recovery;2 cases of fever occurred and white blood cell count elevated and were treated by effective antibiotic treatment;there was no perforation,wound bleeding and death.Conclusions Using the EST to treat the choledocholithiasis of elderly patients has good clinical effects and low risk;through careful observation and nursing,can reduce complications,promote the patients'early recovery and improve quality of life of elderly patients with choledocholithiasis.

Aim To study the role of nitric oxide by measuring the expression and activity of nitric oxide synthase in hippocampus of rats tolerance and dependence to the anticonvulsant action of flurazepam.Method Animal models of toleran and dependence to flurazepam were established. Nitric oxide synthase in hippocampus was measured using Western blot and immunohistochemistry, and its activity was evaluated using colorimetry. Result Hippocampal nNOS increased in rats tolerance to flurazepam. In rats dependence to flurazepam, hippocampal nNOS increased but without statistical significance. Total NOS activity increased dramatically both in flurazepam tolerane and dependene rats.Conclusion NO may play a role in rats tolerance and dependence to the anticonvulsant action of flurazepam.

Respiratory failure and respiratory complication are most reasons that result in death of ALS patients.Respiratory support,especially non-invasive Bi-level positive airway pressure,may improve living quality and prolong survival time.Treatment of respiratory support was gradually accepted and focused in the worldwide.In addition,malnutrition is an independent poor prognostic factor for ALS.Percutaneous endoscopic gastrostomy can ensure enough energy intake,improve nutritional status and prolong survival time.The profit and indication of BiPAP and PEG were Summarized.
