Objective To investigate the changes of stress response on inhalation-intravenous general anesthesia during pericystectomy for Liver hydatid cyst. Methods Thirty ASA I-II patients with liver hydatidosis for pericystectomy were studied. The blood from right jugular vein were collected for measurement of serum cortisol (Cor) concentrations and glucose (BG) levels, and MAP, HR and BIS were observed and recorded at different point-times: pre-intubation for 1 min, post-intubation for 3 min, pre-incision for 1 min, post-incision for 3 min, post-incision for 10 min, post-surgical exploration 10 min. The data of pre-intubation and pre-incision served as controls. Results The levels of Cor concentration of post-incision for 10 min were decreased than those of pre-intubation and pre-incision (P<0.05); MAP of post-incision for 10 min and post-surgical exploration for 10 min were increased than those of pre-intubation and pre-incision (P < 0.01); For HR, the data of post-surgical exploration 10 min was much quicker compared with pre-incision (P < 0.01), which is slower than that of pre-intubation(P<0.01). Conclusion Inhalation-intravenous general anesthesia may inhibit the stress response during intubation,incision and surgical exploration for liver hydatidosis pericystectomy. Hemodynamic changes during incision may reflect the trend of stress response in advance.

BACKGROUND:The reasons for spinal imbalance include spinal deformity, spinal degenerative disease osteoporotic vertebral compression fractures. We believe that the power factor (back muscle) plays a key role in spinal sagittal imbalance. OBJECTIVE:To analyze the reasons for spinal sagittal imbalance by observing clinical manifestations and therapeutic outcomes in patients with osteoporotic vertebral compression fractures. METHODS:A total of 41 patients with osteoporotic compression fractures combined with spinal sagittal imbalance were retrospectively analyzed from January 2012 to May 2013. Al patients were subjected to percutaneous bal oon vertebroplasty under local anesthesia. Before treatment, they received bone density, standing ful-spine lateral X-ray, CT and MR imaging with injured vertebrae as the center. Using standing ful-spine radiographs, the height of anterior border of the injured vertebrae, Cobb angle of kyphosis and improved angle, wedging angle of the injured vertebrae and improved angle were measured. The patients underwent weight loading test and walking test. Preoperative and postoperative data were compared. RESULTS AND CONCLUSION:The patients affected spinal sagittal imbalance symptoms, so the walking distance was significantly shorter than that postoperatively (P<0.05). Moreover, the time of weight loading test was significantly shorter than that postoperatively (P<0.05). In standing ful-spine radiographs, the average difference of Cobb angle was (10.01±0.76)°. The mean difference of vertebral wedging improvement was (4.84±0.40)° (P<0.05). Al patients were fol owed up. Low back pain and sagittal imbalance symptoms were relieved. No severe complications appeared after percutaneous bal oon vertebroplasty. Results indicated that patients with osteoporosis compression fractures can affect the symptoms of spinal sagittal imbalance, which is not only induced by wedging of the injured vertebra. In addition, after percutaneous bal oon vertebroplasty, imbalance symptoms are apparently improved, suggesting that back pain after spinal fracture limits back muscle strength and is an important cause for spinal sagittal imbalance.

Objective To share the experience of heart thransplantation. Methods 3 recipients with terminal myocardiosis were reviewed. The transplantation was performed with inferior and superior vena anastomofic technique. During perioperative period, we selected and maintained the recipients, protected donor-isolated heart, supported circulation,decreased immune reaction and controlled infections. Results All the 3 patients survived. Heart function improved from NYHA class 1V before heart transplant to NYHA class Ⅰ, Ⅱ. The follow-up time was 19 months ,28 months and 49 months respectively. Rejection occurred in two cases due to non-compliance to medication. Conclusions Suitable recipient, proper donor heart procurement and preservation, suitable maintenance of circulation, proper managements of anti-immunitive reaction, prevention of infections are critical for successfal heart transplantation. Medicine-take required may avoid or reduce rejection.

Aim Toexaminethecombinedeffectsof 5-ALA and metformin on diabetes mellitus induced by streptozotocin( STZ) in mice, and to discuss the mech-anisminitially.Methods Thediabeticmiceinduced by intraperitoneal injection of STZ were treated with 5-ALA and/or metformin for 30 days. Physical signs, fasting blood glucose ( FBG ) , fasting plasma insulin ( FIns) , plasma leptin ( Lep) , glucose tolerance, and histological changes of liver and pancreas were as-sessed. Insulin resistance was evaluated by the homeo-stasismodelassessment(HOMA).Results There were more significant effects when 5-ALA combined with metformin than only using metformin on lowering FBG, FIns and Lep. And 5-ALA combined with met-formin could improve glucose tolerance and the insulin sensitivity. Microscopic analysis demonstrated that sig-nificant changes in pancreatic islet and characteristic feature of the vacuolization phenotype in liver was ob-served on diabetic mice, and use of 5-ALA could in-hibit shrinking pancreatic islet number and hepatic morphological changes, especially in combination with metformin.Conclusions Asynergisticeffectof5-ALA and metformin is observed. Combined therapy of 5-ALA and metformin can decrease FBG and improve glucose tolerance, insulin sensitivity and islet ? cells function and morphology.
