Objective To explore the relationships between plasma vasoactive intestinal peptide(VIP),superoxide dismutase(SOD),malondialdehyde(MDA) and hypoxic-ischemic brain damage(HIBD) in neonates with asphyxia.Methods Sixty-eight full-term neonates hospitalized with asphyxia were enrolled in this study (simple asphyxia group 15 cases,mild HIE group 17 cases,moderate HIE group 22 cases and severe HIE group 14 cases) according to the diagnostic criteria of neonatal hypoxic- ischemic encephalopathy(HIE),and 20 cases in control group.Plasma VIP,SOD and MDA were detected by radio-immuhoassay,thiobarbatic acid colorimety and xanthine oxidase at d1 and d7 after born in every group.Results 1.There were significant difference in the plasma VIP,SOD and MDA among every group(Pa

Objective To explore the changes of proteins level of TLR2 in colonic mucosa of ulcerative colitis( UC) model rats and to observe the effects of Kuijieling Decoction( KD) on TLR2. Methods UC model rats were induced by TNBS. The rats were randomly divided into six groups as follows: normal control (NC) group, model control (MC) group, lowdose Kuijieling (KLD) group, mediumdose Kuijieling( KMD) group, high- dose Kuijieling (KHD) group and SASP group. After 10- days treatment the rats were killed to get their colonic mucosa and extract the whole- cell proteins. Western blot technique was used to detect the TLR2 protein level. ? - actin was used as the internal index. Relative expression level of target protein was calculated from the gray scale ratio of TLR2 and ? - actin. Results Relative protein expression level of TLR2 in MC group was significantly higher than that in NC group (P

Neurology is one of the most difficult subjects in clinical medical education.How to improve the teaching model of neurology is a crucial problem.The systematic instructional design and problem-based learning (PBL) emerge as mature teaching techniques,and having a broad application prospect.However,simple PBL teaching model has not achieved the desired results,because PBL teaching method pays excessive attention to the subjective initiative of students,but ignores the supervision and assessment mechanisms,such as assessment,feedback,adjustment,which are the major concerns of systematic instructional design.This research tries to combine systematic instructional design with PBL teaching model,and explore the position in neurology teaching.By determining the teaching target,analysis of PBL teaching,writing teaching plans,organization of PBL teaching,feedback to adjust teaching design method,the final summative evaluation is done and the teaching,was completed.After practice tips may bring progress on neurology teaching mode.

ObjectiveTo explore the clinical outcomes of posterior lumbar interbody fusion using BTwin expandable spinal spacer with microendoscopic discectomy (MED) for lumbar disc herniation accompanying degenerative instability.MethodsFrom March 2006 to May 2010,87 patients with lumbar disc heniation (only one level) accompanying degenerative instability were managed with posterior lumbar interbody fusion using B-Twin with MED,includeing 49 males and 38 females with an average of 47.6 years(range,37-65).Objective level located in L3,4 in 2 cases,L4,5 in 43,and L5S1 in 41.The patients were treated with single BTwin(Single group,n=51) and double B-Twin(Double group,n=36).Clinical outcomes were evaluated with surgical time,blood loss,visual analogue scale (VAS) scores,Oswestry disability questionnaire (ODI),and the pre- and post-operative disk space heights.ResultsThe patients were followed up for an average of 35.8months (range,12-46).All the patients felt the low back pain and radiation pain disappeared or relieved apparently.The mean preoperative ODI and VAS scores decreased from 78％±3％ to 18％±3％,and (8.70±11.3)to (0.65±10.48) at the final follow-up respectively.Disc space increased from a pre-operative height of (8.76±1.3) mm to a post-operative of (11.8±0.6) mm.ODI,VAS and the disk space heights in all patient showed statistical significance,which revealed no statistical significance between the two groups.However,the operation time,blood loss were statistical difference between the two groups.All the patients achieved solid union or probable union at a mean time of 5.6 months (range,3.9-8.6).ConclusionPosterior lumbar interbody fusion using B-Twin with MED can obtain satisfactory outcomes in the treatment of lumbar disc herniation accompanying degenerative instability.Single B-Twin can get similar clinical outcomes,but shorter surgical time,less blood loss,and less medical costs.

Objective To evaluate and compare the efficacy of holmium laser enucleation of the prostate(HoLEP) and plasmakineticenucleation of the prostate(PKEP) for treating benign prostatic hyperplasia (BPH).Methods A total of 86 cases of BPH were selected from the Shandong Energy Zibo Mining Group Co.Ltd Central Hospital from January 2013 to June 2014.The patients received either HoLEP (40 cases) or PKEP(46 cases) treatment.Clinical data including postvoid residual volume (PVR),international prostate symptom score(IPSS),quality-of-life score(QOL score),maximum urinary flow rate (MFR) were evaluated before and 3 months after operation.Blood loss in operation,operation time,weight of resected prostate tissue,bladder irrigation time,catheterization time and length of hospital stay were also collected from the perioperative period.Results Three months after surgery,PVR,IPSS,QOL and MFR were all significantly improved in both HoLEP and PKEP groups compared with the data before operation (P =0.000),while there was no significant difference between the two groups(P＞0.05).Patients from the HoLEP group showed markedly lower values of bone loss in operation than that of PKEP group((69.5±23.6) ml vs.(87.5±38.0) ml,P=0.011).There were no significant differences in terms of other indexes (P＞ 0.05).Conclusion HoLEP and PKEP have similar efficiency in treating BPH,while HoLEP is suggested superior in regard of bone loss.

Objective To analyze safety,efficacy and resection methods of video-assisted thoracic surgery(VATS) for the treatment of intralobar pulmonary sequestration(IPS).Methods Data of 17 patients who were diagnosed as IPS and received VATS from December 2006 to September 2011 were retrospectively analyzed.The patients were 7 males and 10 females with the mean age of 40.3 (14-61) years.Diagnosis was confirmed in 9 patients by enhanced CT and unconfirmed in 8 patients.Three ports were used for surgery.After the aberrant artery was confirmed,liner stapler was used in 16 patients to cut it and Hem-o-lok was used in 1 patient because the aberrant artery was about 3 mm in diameter and long enough.If the diameter of the aberrant artery was longer than 10 mm,a stapling device without knife was used to occlude it centrally and a second stapling device was used to cut it peripherally.Wedge resection or lobectomy was performed due to the different conditions.When the lesion was small with linited range in CT image and the lesion was easily distinguished from normal lung tissue during operation,wedge resection was preferred.Results Seventeen patients underwent VATS successfully without any conversion to thoracotomy or any serious complications.Five patients were planned to receive wedge resection and one was converted to lobectomy.Another 12 patients were planned to receive lobectomy and all succeeded.The mean operating time was 128 (80-170)min.The mean blood loss was 80 (5-200) ml.The mean days of chest tube maintained were 4.0 (2-6) days.The mean postoperative hospitalization days were 7.6 (4-11) days.All patients were diagnosed as IPS according to operating in-sight and postoperative pathology.There was no patient suffering from chronic cough,bloody sputum or recurrent pneumonia during the follow-up.Conclusion VATS for the treatment of IPS is safe and feasible.If conditions permit,wedge resection or segmentectomy may be preferred.

Objective To compare the bleeding volume during endoscopic sinus surgery in pa-tients with hypertension under total intravenous anesthesia or combination of intravenous with inhaled anesthesia.Methods Forty adult patients with hypertension (ASA Ⅰ or Ⅱ),male 25 and female 1 5,aged 35-54 years,agreed to be on electively endoscopic sinus surgery,were divided randomly into two groups(group A and group B,n =20 each).All patients were injected intravenously with fenta-nyl,propofol and cisatracurium during the induction of general anesthesia.During the maintenance stage of the general anesthesia,patients in group A were injected intravenously with propofol,and patients in group B were inhaled with sevoflurane until 5 minutes before the end of the operation.BIS was 40-60 during the operation in the two groups.After induction of anesthesia and tracheal intubation,ni-troglycerin and esmolol were given to adjust blood pressure and hypervolemic hemodilution was performed.. Bleeding volume and operation duration were recorded at the end of the operation.The arterial blood gas, blood lactate and coagulation function were monitored 30 minutes before the operation (T0 ),30 minutes (T1 )and 90 minutes after the operation beginning (T2 )and 30 minutes after the end of the operation (T3 ). Results Bleeding volume in group A was significantly less than that in group B (P <0.05).Fifteen minutes before the operation,the MAP of all the patients in two groups was controlled slowly to 60 mm Hg.Com-pare to those at T0 ,there was no significant difference in the arterial blood pressure,blood lactate and coag-ulation function at T1 ,T2 and T3 .Conclusion During the endoscopic sinus surgery with intravenous anes-thesia for patients with hypertension,the bleeding volume was less than that with inhalation anesthesia.
