Objective To explore the effects of electro-acupuncture combined with surface gastric pacing on gastrointestinal dysfunction for patients with spinal cord injury (SCI).Methods Seventy-five SCI patients with gastrointestinal dysfunction were divided randomly into an electro-acupuncture group (group A),a gastric pacing treatment group (group B) and a group for which electro-acupuncture was combined with gastric pacing (group C).There were 25 cases in each group.Members of group A were given 30 minutes of electro-acupuncture per day ; those of group B had 30 minutes of gastric pacing treatment twice per day ; group C was provided with both 30 minutes of electro-acupuncture and one 30-minute gastric pacing treatment per day.All of the interventions lasted ten days.Before and after the treatment,all patients were assessed using a clinical symptoms score and with electrogastrograms,and any adverse effects were observed.Results There was a significant improvement in upper abdominal pain and epigastric discomfort,bloating and early satiety,nausea,vomiting,as well as belching and loss of appetite in each group after treatment.Before treatment there was no significant difference in the average clinical symptom scores of the three groups.After treatment the values had decreased,and those of group C were significantly lower than group A or B.The average scores of groups B and A were not significantly different.The electrogastrogram results showed than after treatment there was significant improvement in N％ and T％ in groups A and B,and also significant improvement in N％,B％ and T％ in group C compared to before treatment.Group C's improvements were all significantly greater than those observed in groups A and B.Conclusion Electro-acupuncture or gastric pacing alone can give some improvement in gastrointestinal function and its electrophysiological indicators,but their combined effects are better than when either is used alone.

Objective To develop the hypothesis ‘saturated or non-saturated cytotoxicity model' and explain the various phenomena of antibody mediated immunoresponses in recipients,including rejection and accommodation.Methods The imitating complement dependent cytotoxicity.The threshold set to identify as saturated or non-saturated cytotoxicity depends on antigen-antibody complex(R)whether or not above lethal number(D)in effective time.Feasibility of the hypothesis was examined through explaining various phenomena mediated by anti-donor antibodies,especially some contradictory phenomena.Results Hyperacute rejection,accelerated rejection and acute rejection could be well explained by saturated cytotoxicity.Accommodation of ABO imcompatible transplantion,de novo antibody induced injury,change of protein profile,and C4d deposition in graft could be well elucidated by the hypothesis.Conclusion The hypothesis saturated or nonsaturated cytotoxicity model' help to interpret and interconnect various phenomena of antibodies mediated immune response,such as rejection and accommodation.

Background With the changes of diet and living style,the diabetes has become the major diseases affecting human health.Diabetic cataract is a common complication of diabetes. Objective The present study was to investigate the difference of lens proteomics between diabetic cataract and age related cataract using two dimensional electrophoresis (2-DE) and mass spectrometry in order to postpone happening of diabetic cataract and offer the effective approach to the prevention and therapy of diabetic cataract. Methods The lenses were obtained from 8 diabetic patients and 12 age-related cataract patients during the surgery to extract the protein by lysis and centrifugation.The lens proteins were separated using immobilized pH gradients 2-DE.Image analysis was carried out using PDQuest Advanced-8.0.1 software package.Significant difference of the crystallines was identified by matrixassisted laser adsorption/ionization time of-flight-mass spectrometry (MALDI-TOF-MS) and peptide mass fingerprint combined with protein database. Results The maps of 2-DE showed that lens proteins of diabetic cataract and age related cataract were in the section of pH 5-9 with the relative molecular weight 14000-97000;while relative molecular weight of more abundant crystalline was localized at 20000-31000.About 3 differential protein spots were detected by image analysis software.Two crystallines,αB and βB1 crystallin,were identified using MALDI-TOF-MS.Conclusions Proteomic analysis of lens can be accomplished and the proteins can be well separated,moreover,differential proteins can be analyzed using 2-DE and mass spectrometry between diabetic cataract and age related cataract.These results indicate that αB and βB1 crystallin proteins accelerate the development of diabetic cataract.This technique offers a new avenue for clarity of lens proteins of diabetic cataract other than age related cataract.

OBJECTIVETo evaluate surgical strategy and clinical outcomes for the treatment of thoracolumbar metastatic tumor.

METHODSFrom January 2009 to December 2010,42 patients with thoracolumbar metastatic tumor were treated surgically. Among the patients, 30 patients were male, and 12 patients were female, ranging in age from 28 to 76 years old, with an average age of 56.8 years old. Twenty-five patients had metastatic tumor in thoracic vertebraes, and 17 patients had metastatic tumor in lumbar vertebraes. Thirty-four patients had metastatic tumor in 1 segment, 6 patients had metastatic tumor in 2 segments and 2 patients had metastatic tumor in 3 segments. Two patients had no symptoms and 40 patients had back or leg pain. Eighteen patients had neurologic deficits, and 5 patients had injuries of A degree, 3 patients had injuries of B degree, 4 patients had injuries of C degree, 6 patients had injuries of D degree according to ASIA grading system. The operation goal was made according to Tomita evaluation. The surgical procedures included pallative decompression, tumor curettage and total vertebrectomy, which were decided based on Tomita classification. The pain, spinal cord function,part control of tumor,survival rate and conditions of internal fixation were evaluated at 1 week, 3 months, 6 months, 1 year and 2 years after operation.

RESULTSOne patient died in the operation. Pain relief was obtained in 38 patients after operation. Among 18 patients suffering from spinal cord compromise, 17 patients improved 1 to 4 grades after surgery according to the ASIA grading system. All the patients were followed up and the duration ranged from 24 to 48 months, with a mean time of 34.2 months. Five patients got recurrence. The postoperative survival rates at 3 months, 6 months, 1 year and 2 years were 95.2%, 85.7%, 58.2%, 37.6% respectively.

CONCLUSIONAccording to Tomita system, the different surgical treatments can be selected for patients with spinal metastatic tumors, which can relieve pain, improve the neurological status and spine stabilization, maintain local control, improve quality of life.

Objective To compare the myocardial protective effects of isoflurane versus sevoflurane in patients undergoing off-pump coronary artery bypass grafting (OPCABG). Methods Forty ASA Ⅱ or Ⅲ patients (NYHA Ⅱ or Ⅲ ) of both sexes, aged 40-55 yr, weighing 55-94 kg, scheduled for elective OPCABG, were randomly divided into 2 groups ( n = 20 each): isoflurane group ( group Ⅰ) and sevoflurane group ( group S). Anesthesia was induced with midazolam, sufentanil and vecuronium. Patients were tracheal intubated and mechanically ventilated. Anesthesia was maintained with inhalation of isoflurane or sevoflurane and infusion of sufentanil and vecuronium. In group Ⅰ, the initial end-tidal concentration of isoflurane was 1.2%. In group S, the initial end-tidal concentration of sevoflurane was 1.7 %. BIS value was maintained at 40-50 by adjusting the end-tidal concentration of isoflurane or sevoflurane. The central venous blood samples were collected immediately before skin incision, at the end of surgery, 2 and 24 h after surgery for determination of plasma creatine kinase-MB (CK-MB) activity and cardiac troponin Ⅰ (cTnI) concentration. The adverse cardiovascular events were recorded. Results The incidences of ventricular premature beat, tachycardia, bradycardia, ventricular fibrillation and S-T segment elevation ( ＞0.1 mV) during surgery and the plasma CK-MB activity and cTnI concentration after surgery were significantly higher in group S than in group Ⅰ ( P ＜ 0.05). Conclusion Isoflurane has better myocardial protective effect than sevoflurane in patients undergoing OPCABG.

Objective To investigate the effecacy of open reduction internal fixation in cases with rib fracture. Methods The pain scores,respiratory related clinical indicators change of 81 rib fractuure cases underwent open reduction internal fixation surgery were ob-served. A comparison was made between the surgical group and the non-surgical group of 37 cases on pain scores trend and hospital stay. Re-sults All operations were successfully completed and postoperative recovery was good. Postoperative pain scores and respiratory rate was sig-nificantly lower(P=0. 000),Oxygen saturation was significantly higher(P=0. 002),the proportion of expectoration difficult,dyspnea and ac-tivities inconvenience were significantly lower(P<0. 05). Pain scores of surgical group significantly decreased after surgery peak hours that was the fourth day hospitalized,but the overall decline of pain scores in non-surgical group was slow. The hospital stay between the surgical group and the non-surgical group was not significantly different(P=0. 084). Conclusion The efficacy of open reduction internal fixation is significant to rib fracture with exact surgery indications,and appropriate timing of surgery is the fourth day after admission.
