This work aims to compare the curative effect of transumbilical single-port laparoscopic cholecystectomy (TUSPLC) and four-port laparoscopic cholecystectomy (FPLC). 200 patients with cholecystolithiasis were enrolled in this study. They were randomly divided into TUSPLC group and FPLC group, 100 cases in each group, and the TUSPLC and FPLC was performed, respectively. The surgical time, intraoperative complication, conversions rate, postoperative pain, postoperative analgesic drug use, incision infection, postoperative hospitalization time and postoperative cosmetic results in two groups were compared. ⋯ TUSPLC has obvious advantage in treatment of Nassar grade I patients with cholecystolithiasis. It can be used as a supplement for standard laparoscopic gallbladder surgery. It is safe and feasible, without abdominal scar, thus achieving to excellent cosmetic result and high satisfaction in patients.

This study was designed to compare the effects and mechanisms of transcutaneous electroacupuncture (TEA) on rectal distention (RD)-induced intestinal dysmotility with EA. ⋯ RD inhibits postprandial intestinal motility. Both EA and TEA at ST-36 are able to improve the RD-induced impairment in intestinal contractions, transit and slow waves mediated via the vagal mechanism. Needleless TEA is as effective as EA in ameliorating the intestinal hypomotility.

Brachial plexus perineural blocks provide specific analgesia for upper limb surgery. We present our experience with ultrasound-guided supraclavicular brachial plexus perineural blocks for distal upper limb surgery. Although single-injection ultrasound-guided supraclavicular blocks have been reported, little is known about the advantages using this approach compared with nerve stimulator guided. ⋯ Supraclavicular brachial plexus perineural insertion using ultrasound guidance is feasible and almost have no complications, deserves further study with a randomized controlled trial comparing this relatively new technique with only using nerve stimulator.

The aim of this study is to investigate the effect of porous tantalum material in repair tibial defects caused by firearm injuries in a rabbit model. A multifunctional biological impact machine was used to establish a rabbit tibial defect model of firearm injury. Porous tantalum rods were processed into a hollow cylinder. ⋯ By the 16th week, the areas of bone tissue of the firearm injury group was significant higher than that of non-firearm injury group (P<0.05). The comminuted fractures treated with tantalum cylinders exhibited greater bone ingrowth in the firearm injury group. In conditions of firearm injuries, the porous tantalum biomaterial exhibited bone ingrowth that was beneficial to the treatment of bone defects.

Postoperative cognitive dysfunction (POCD) is a subtle impairment of cognitive abilities and can manifest on different neuropsychological features in the early postoperative period. It has been proved that the use of mechanical ventilation (MV) increased the development of delirium and POCD. However, the impact of variable and conventional lung protective mechanical ventilation on the incidence of POCD still remains unknown, which was the aim of this study. ⋯ Variable vs conventional lung protective MV decreased the incidence of postoperative delirium and POCD by reducing the systemic proinflammatory response.
