Objective To observe the effects of Melatonin on hippocampal neuron apoptosis and caspase-3 expression in epileptic rats. Methods Using model of status epilepticus (SE) induced by Pilocarpine, the rats were administered with melatonin (melatonin group) or saline (Pilocarpine group) before Pilocarpine injection. The apoptotic neuron was detected by TdT-mediated dUTP Nick End Labeling (TUNEL) and caspase-3 expression was observed by immunocytochemistry method, respectively.Results In Pilocarpine group, the number of TUNEL positive neurons began to increase at 6 h post-SE, peaked at 72 h post-SE, and decreased at 7 d post-SE. Caspase-3 immunoreactivity began to increase at 6 h post-SE, peaked at 48 h post-SE, especially in CA1 and CA3 region of hippocampus, began to decrease at 72 h post-SE and dropped to normal level at 7 d post-SE. The numbers of TUNEL positive neurons and caspase-3 expression in Melatonin group were significantly decreased compared to Pilocarpine group at different time points (all P

Objective To study the feasibility and safety for using anesthesia gastroscopy in aged-patients over 80 years old.Methods Selecting 84 cases of aged-patients over 80 years old as anesthesia group(group 1),22 cases of aged-patients over 80 years old as normal gastroscopy group(group 2)and 100 cases of young-middle age as anesthesia control group(group 3).Low dose propofol and fentanyl combined atropine were injected into venous in anesthesia gastroscopy.The BP,HR,SpO2,patients reactions during gastroscopy,stomach peristalsis rates,awake time were detected before,during and after gastroscopy.Results Patients in group 1 felt much less discomfortable than those in group 2.Anesthesia group felt much satisfactorily than normal gastroscopy group.The BP,HR,SpO2 in group 1 were decreased transitorily during examination and resumed rapidly after examination.There were no severe complications in anesthesia gastroscopy.However,the BP and HR were increased obviously in normal gastroscopy group.The dosage of propofol in group 1 was much less than that in group 3.Conclusions The use of anesthesia gastroscopy with low dose propofol and fentanyl combined atropine intravenously in aged-patients over 80 years old is safe and comfortable.

Objective To probe the changes of nitric oxide (NO) content and caspase-3 mRNA expression in hippocampus and the correlation between NO and caspase-3 mRNA expression post-status epilepticus (SE). Methods The models of SE were induced by pilocarpine. The nitric oxide content was detected by chromatometry and caspase-3 mRNA expression was observed by reverse transcription polymerase chain reaction (RT-PCR) method. Results The level of NO increased rapidly at 6~72 h post-SE,and was still significantly higher than that of the controls (all (P)0.05).Conclusions The peak expression of nitric oxide is earlier than caspase-3 mRNA post-SE, although they have the similar diversity tendency. Nitric oxide pathway is definitely involved in the seizure initiation and correlated with caspase-3 activation.

Objective The investitgation of vascularized periosteal flap with dorsal branch of anterior interossea vessel was performed to provide anatomical basis for periosteal flap transposition. Methods The courses, branches, distribution and anastomosis of the dorsal branch of anterior interossea vessel were observed on 30 sides of adult cadavers' upper extremities and stimulated operation were perfomed. Results The dorsal branch penetrate out of interosseous membrane of forearm at (6. 6? 1. 4) cm upper the styloid process of the radius. It also sent off branches to the dorsal of ulna and radius that consist the periosteal flap. The dorsal branch send off lateral and medial branch about (2. 6?0. 8) cm upper the styloid process of the radius. The end of the branch anastomoses with dorsal carpal branch of the ulnar and radial vessel' Conclusion The pedicled osteoperiosteal flap can be transferred for repairing the fracture nonunion of ulna and radius and transpose reversely to repair scaphoid and innate bone disease'

Objective To analyze the clinical conditions and emergency treatment experiences of acute and chronic renal failure with hyperpotassemia. Methods Retrospective analyzed 542 clinical cases of supervening hyperpotassemia, which were treated by hemodialysis on 186 patients of renal failure with hyperpotassemia for 5 years. Results 540 cases clinical symptom was improved, serum potassium concentration was down to normal range and hyperpotassemia disappeared in electro cardiogram. 2 cases died after salvage. Rate of success was 99.6%. Conclusion Hemodialysis therapy is the most effective treatment to hyperpotassemia. Use bicarbonate with kalium pH indicator of 3.0～3.5mmol/L in dialysis is useful to lower hyperpotassemia, and safe also. In the early stage of hemodialysis, pure ultrafiltration dehydration treatment is not suitable. There is still danger of heartbeat stop deal to high kalium in the early stage of dialysis; emergency treatments should be standby all the time.

Objective To identify the role of resistin in insulin resistance(IR) by endoplasmic reticulum(ER) stress in human umbilical vein endothelial cells ( HUVECs) and in rats.Methods HUVECs were cultured in vitro and disposed by resistin (R) or tauro ursodesoxycholic acid (tudca).Expressions of GRP78, P-akt and P-eNOS were determined using Western blotting.Thoracic aortic rings were made and their dilation function exposed to different concentrations of insulin was detected.Changes of vascular morphology were observed by HE staining.Results Results of Western blotting showed that expression of GRP78 was remarkably increased,but P-akt and P-eNOS were markedly decreased in R group.However, there was no difference in expressions of GRP78, P-akt and P-eNOS between tudca group and control group.The insulin induced vasodilation was decreased in R group and there was no difference between tudca group and control.Using HE staining, the R group showed significant medial thickening and proliferation of smooth muscle.Conclusion Resistin can induce insulin resistance in vascular endothelium cells by ER stress.

We report a case of a 35-year-old right-handed male patient with drug-resistant mesial temporal lobe epilepsy who developed ipsilateral occipital hematoma after right temporal anterior lobectomy and amygdalohippocampectomy. Patient did not report taking any drugs with anticoagulant effect, such as aspirin or valproate. There was no past history of hypertension and the pre-operation tests were normal. Pre-operative brain magnetic resonance imaging revealed no abnormality in the right occipital lobe. Overdraining of cerebrospinal fluid may have triggered this remote cerebellar hemorrhage.

Objective To investigate the charateristics of pathological changes in hippocampal subregions in rats with epilepsy induced with different doses kainic acid(KA) ,discuss the etiology and pathway of epileptic wave.Methods 30 male Wistar rats were randomly divided into control group,low(0.025 ?g) and high(0.1 ?g) dose KA injection groups with 10 rats each.KA was focally injected into the right amygdala by a glass micropipette connected to an air pressure system to make epilepsy model.The pathological characteristics in hippocampal subregions in rats with epilepsy induced with different doses KA were observed.Results Compared with control group,high dose KA injection mainly caused neuron loss in the CA3 region,while pyramidal and dentate granule cells were evenly distributed with normal shape and size.Low dose KA injection caused severe damage in both CA1 and CA3 regions.Dentate granule cells didn't show any pathological change and neuron loss in low dose injection.Conclusion The pathological changes in hippocampal subregions in rats with epilepsy induced with KA are different with different doses KA,it might be related to the pathway of epileptic wave and the specific properties of hippocampus.

OBJECTIVE:To evaluate the effect and safety of conservative treatment for treating cervical spondylotic radiculopathy by cochrane evaluation systems.DATA SOURCE:CBM(from January 1978 to October 2008),CNKI(from January 1978 to October 2008)and VIP(from January 1989 to October 2008)databases were retrieved by computer and partial documents were searched by hands.DATA SELECTION:Randomized controlled trial was adopted in course of acupuncture and moxibustion treatment for cervicel spondylotic radiculopathy and its quailty was assessed.Dafa source was randomized and semi-randomized controlled.Some evaluations such as random method-selection bias,allocation concealment-selection bias,blind method-performance bias and measurement bias,exclusion.lose to follow-up,withdraw-attrition bias were chosen.MAIN OUTCOME MEASURES:①Abdominal acupuncture needles were superior to the conventional method's efficiency.②Electro-acupuncture plus cupping with barbed floc were superior to the conventional method's efficiency.③Abdominal acupuncture were superior to traction's efficiency.④Cervical traction,electro-acupuncture combined with point injection and massage were superior to traction's efficiency.⑤Traction,electro-acupuncture,massage,TDP-guided were superior to traction,physiotherapy,TDP combined with exercise therepy's efficiency.⑥Vinegar iontophoresis and electro-acupuncture were superior to simple electro-acupuncture's efficiency.⑦Long's approach acupuncture was superior to simple acupuncture's efficiency.⑧Adverse reaction.RESULTS:A total of 1416 subjects were selected from 7 randomized controlled trials.All the studies have selection bias,measurement bias,loss of the high probability of bias,the quality and grade of"C"grade.And only one study proved that the efficiency of the experimental group was better than that of the control group.Study 1 showed that there was insufficient evidence suggested that acupuncture treatment of abdominal cervical spondylotic radiculopathy was efficient than conventional acupuncture.Study 2 showed that there was insufficient evidence suggested that electro-acupuncture plus cupping therapy with barbed floc was efficient than conventional acupuncture to cure cervical spondylotic radiculopathy.Study 3 showed that there was insufficient evidence suggested that acupuncture treatment of abdominal cervical spondylotic rediculopathy was efficient than traction.Study 4 showed that the cervical traction,electro-acupuncture combined with acupoint-injection treatment of cervical spondylotic radiculopathy was efficient than traction combined massage therapy.Study 5 showed that there was insufficient evidence suggested that traction,electro-acupuncture,massage,TDP-guided therapy was efficient than traction,physical therapy,TDP combined with exercise therapy.Study 6 showed that there was insufficient evidence suggested thatelectro-acupuncture combined with vinegar iontophoresis treatment of cervical spondylotic radiculopathy was better than the simple electro-acupuncture therapy.Study 7 showed that there was insufficient evidence suggested that the acupuncture therapy using Long's approach was better than simple acupuncture.No adveme reactions appeared to terminate the test in 7 studies.CONCLUSlON:The above seven studies mainly present with low quality,absence of a unified curative method,small samples,difference of follow-up time,iudgment standard and measurement standard.So more samples,multicenter and more regular randomized controlled trial should be performed.

Objective To investigate the expression of connexin CX43 using hybridization techniques after GABA restraining receptor gene was transferred into the supramammillary of hypothalamus in Kainic acid(KA) induced epileptic rats.Methods Twenty-four male Wistar rats were divided into four groups: control group(n=2),surgery group(n=2),KA group(n=10) and GABA restraining receptor gene transferred group(GABA group)(n=10).No treatment was given to the control group.Physiological saline(1 ?L) was injected into right amygdala of rat in surgery group.In KA group,KA(1 ?L,1 ?g) was injected into the amygdala of rat to build epileptic model.In GABA group,the GABA restraining receptor gene(400 nL,40 ng) was transferred into the supramammillary of hypothalamus by HVJ-liposome 48 h before KA was injected into amygdala.The expressions of CX43 mRNA and morphological changes different time(3 h,6 h,24 h,3d,7d) were observed by in situ hybridization in each group.Results In control group and surgery group,the morphological manifestations were normal,and the hippocampus structures were complete.In KA group,swell and degenerative hippocampus neurons were showed and deteriorated with time.In GABA group,the degeneration and necroses of hippocampus neurons were relatively alleviated.The positive expression of CX43 mRNA was few in control group and surgery group.And in KA group it increased with time.In GABA group,the positive expression of CX43 mRNA was fewer than that of KA group at every period.Conclusion The expression of CX43 mRNA in hippocampus can be decreased by transferring GABA receptor gene into hypothalamus.
