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 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 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 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 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.

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.

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.

Objecltive To intensify the coordination and nursing in the operation room in order to prevent surgical site infection after gastrointestinal operation. Methods 337 medical history of patients received gastrointestinal operation and third rate healing from 1999 to 2006 were collected. A series of intensified measures were applied to surgical site infection from 2003 gradually, including invocation of new surgical handwashing method, modified skin disinfection manner, adoption of degreasing with ethanol first before disinfection with iodophor, placement of incision protector and clean bag for incision protection after entering abdomen, changing to use new gastrointestinal anastomofic thimerosal,standardization of operation order and clean manage-ment in operation room. The incidence rate of surgical site infection after gastrointestinal operation of patients from 1999 to 2002 and from 2003 to 2006 underwent χ2 test. Results The incidence rate of surgical site in-fection after gastrointestinal operation greatly decreased after adoption of intensified nursing intervention, Signifi-cant difference existed in rate of patients with third rate healing between the year 1999 to 2002 and 2003 to 2006. Conclusions Modified nursing intervention for surgical incision after gastrointestinal operation can de-crease incision infection rate evidently.

Objective To evaluate outcomes of modified transforaminal lumbar interbody fusion (TLIF) assisted by the minimally invasive expandable access system and spinal channel endoscope for acute and chronic lumbar intervertebral disc injury.Methods From March 2013 to November 2014, 45 patients with lumbar intervertebral disc injury were managed with minimally invasive (Group A) or open TLIF (Group B).Location for disc injury was at L3/4 in 5 patients, L4/5 in 28 patients and L5-S1 in 12 patients.Group A composing 12 males and 10 females showed age of (53.70 ±3.59) years (range, 43 to 67 years).Group B composing 14 males and 9 females showed age of (54.80 ± 4.37) years (range, 42 to 68 years).Between-group comparison was conducted with respect to operation time, blood loss, postoperative drainage loss, ambulation time and postoperative complications.Clinical outcomes were evaluated using the visual analogue scale (VAS), Oswestry dysfunction index (ODI), and bone fusion rate.Results Except for the comparable operation time, group A was associated with better results in the blood loss [(152.1 ± 15.5) ml vs (409.9 ± 28.3) ml], drainage volume [(106.1 ± 14.3)mlvs (223.0 ± 19.4)ml], ambulation time[(4.5 ±1.1)d vs (8.9 ±1.4)d] and 1-week postoperative VAS [(3.0±0.7) points vs (4.7 ±0.4) points] (P ＜0.05).At the final follow-up, VAS and ODI of both groups were significantly improved compared to the preoperative levels (P ＜ 0.05), but the differences between groups were insignificant (P ＞0.05).Bone fusion rate in Group A was 95％ (21/22) versus 96％ (22/23) in Group B 6-month postoperatively (P ＞ 0.05).No nerve root injury, intervertebral space infection or other complications occurred.Conclusion Modified TLIF assisted by the minimally invasive expandable access system offers the benefits of less trauma, less bleeding and a quicker recovery for acute and chronic lumbar intervertebral disc injury and has similar long-term clinical outcomes with open TLIF.
