Objective To discuss the anesthesia experience for the elderly patients undergoing total. Methods All 50 cases received the epidural anesthesia, during the operation, MAP,HR and SPO2 were monitored. The blood glucose was monitored for each 45 minutes for the diabetes patients. Results All patients satisfied with the effect of epidural anesthesia, blood pressure dropped to varying degrees, the appropriate colloidal solution was used to expand capacity, prepared baek-ephedrine and alropine. These measures help maintain a stable blood pressure, iinprove the blood indexes, save blood transfllsion, reduce the ineidenee of lung infection, also provide a good postoperative epidnral analgesia. reduce Ihe occurrence of postoperative complications. Conclusion Continuous epidural anesthesia in ehterly patients with total hip replacement might help reduce postoperative complications and improve the quality of rehabililtation.

Objective To observe the feasibility of laryngeal mask ventilation general anesthesia com- bined epidural block in laparoseopie eholecystectomy. Methods One hundred and forty eases of selective laparoscopie eholecystectomy were performed to T8～T9 gap catheterization, with 1.5 percent lidoeaine epi- dural block, block levels in the following T4. After conventional anesthesia into 4# or 5# LMA, balloon gas was injected in 20 mL～30 mL, manual ventilation, respiratory resistance and the situation thorax ups and downs were observed. Results The patients epidural catheterization smoothly, in the anesthesia plane fol- lowing T4, insert the LMA blood pressure, heart rate without significant change. Pneumoperitoneum after the rebound in blood pressure[(20.6 5.0) mm Hg], heart rate did not change significantly, and then airway pressure increased[(5.7 1.6)cm H2O] , surgery performed smoothly, and quickly regained consciousness after the surgery, when all patients admitted gallbladder, they have resumed breathing independently. Con- dusion Laryngeal Mask Airway general anesthesia combined epidural block cause mechanical damage vocal cords and airway, make the stress response light and the sense of rapid recovery, which is a safe and feasible method of anesthesia.

Objective To provide reliable technical method by identifying referential anatomic landmarks for retroperitoneal laparoscopic renal surgery,with respect to the renal hilum and renal artery.Methods The regional anatomy of the posterior abdominal wall was studied in 35 cases of retroperitoneal laparoscopic renal surgery from January to August 2010.These included 27 cases of renal cancer,6 cases of renal pelvis cancer and 2 cases of renal tuberculosis.Distended the retroperitoneal space using balloon dilation along with sharp and dull dissection.We recorded the forms and positions of the posterior abdominal cavity's anatomical landmarks and evaluated the relationship between each anatomical landmark with respect to the renal hilum and renal artery.Results The perirenal fascia posterior layer and perinephric fat on the renal side were observed,and several anatomical landmarks gradually appeared on the posterior abdominal wall.The diaphragm extended across the upper retroperitoneal space near the superior pole of the kidney,and the psoas major and the quadratus lumborum muscles were located at the lower retroperitoneal space,near the inferior part of the kidney.The intersection of the upper diaphragm muscle with the lower psoas major and quadratus lumborum muscles were bordered by the lateral and medial arcuate ligaments.The lateral arcuate ligament arched across the upper part of quadratus lumborum,while the medial arcuate ligament arched across the upper part of psoas major.The medial arcuate ligament points extended towards the upper border of the renal hilum.These landmarks enable us to locate the position of the kidney,reach the renal hilum and identify the renal vessels in all 35 cases.Conclusions The relative position of the muscles and ligaments of the posterior abdominal wall are consistent and can be clearly seen under retroperitoneoscopy.Based on the position of the diaphragm and psoas major,the kidney can be located.In addition,based on the position of the medial arcuate ligament,the renal hilum and renal artery can be located.Assistance from these anatomical landmarks will simplify the retroperitoneal laparoscopic renal surgery.

MicroRNAs (miRNAs or miRs) are a class of short, non-coding RNAs that participate in various oncological processes. This study aims to explore the roles of microRNA-34a (miR-34a) in invasive urothelial bladder carcinoma. miR-34a was transfected into bladder cancer cell lines 253J and J82. The miR-34a expression levels in tissues and cells were detected by using qRT-PCR. The Notch1 expression was detected by qRT-PCR and Western blotting. Cell migratory and invasive abilities were measured by Transwell chamber assay. Bioinformatics and luciferase assay were performed to predict and analyze the binding sites between miRNA-34a and Notch1. It was found that there was aberrant expression of miR-34a in bladder cancer tissues. Moreover, we revealed that ectopic expression of miR-34a suppressed cell migration and invasion, while forced expression of Notch1 increased cell migratory and invasive abilities. Finally, we observed that miR-34a transfection significantly down-regulated luciferase activity and reduced the mRNA and protein levels of Notch1. Our study concluded that microRNA-34a antagonizes Notch1 and inhibits cell migration and invasion of bladder cancer cells, which indicates the tumor-suppressive function of microRNA-34a in bladder cancer.

Objective: To assess the safety and effectiveness of sufficient, short-term platelet (PLT) transfusion for the surgery preparation of the infantile patients with Kasabach-Merritt phenomenon, who were insensitive to glucocorticoids. Methods: The infantile cases were retrospectively analyzed during May 2011 to December 2016, who were clinically diagnosed as KMP and insensitive to glucocorticoids, received PLT transfusion and surgical resection. PLT transfusion in patients whose PLTC was less than 30×10⁹/L, was 0.3 therapeutic dose(TD)/kg, and 0.2 TD/kg in PLTC≥30×10⁹/L group. The maximum was 1 TD.Criteria of the PLT transrusion: 1 hour after the transfusion, the PLT count (PLTC) were tested and the corrected count increment of platelet (CCI) and practical platelet recovery (PPR) was calculated. PLTC ≥100×10⁹/L, CCI>7.5×10⁹/L and PPR>30% were defined as effective; while PLTC=(50-99)×10⁹/L, CCI>7.5×10⁹/L and PPR>30% as partial effective; PLTC<50×10⁹/L, or CCI≤7.5×10⁹/L, or PPR ≤30% were defined as ineffective. By reviewing the method and response of their PLT infusions, to figure out the most effective way in rising PLT, as a part of pre-operation treatment. Results: There were 46 cases in the research. Based on the PLTC, CCI and PPR 1 hour after PLT transfusion, there were 44 effective transfusion, 2 patients with partial effectiveness, and no ineffective case. There was no allergic or heart failure happened in any cases. No critical potential complications of PLT transfusion occurred, including fluid and iron overload, alloimmunization to human leukocyte antigen and/or PLT antigen. Conclusions Pre-operative sufficient and short-term PLT infusions are more effective than low dose and long-term ones. They can create a more optimistic opportunity for surgical resections.
