Objective To explore feasibility of laparoscopic hepatectomy for hepatic hemangioma.Methods Twelve patients were treated by laparoscopic hepatectomy, including left lateral lobectomy in 5 cases and local liver resection in 7 cases. Three cases of hepatic hemangioma associated with gallbladder stone were performed cholecystectomy synchronously. Results Laparoscopic procedures were successfully performed in all 12 cases. The mean operative time was 155 min. The mean blood loss was 230 mL. The mean postoperative hospital stay was 8 days. The pospostoperative recovery was smooth except that 1 case had pulmonary infection. During a follow-up of 6-20 months for 12 cases,there were no recurrence. Conclusion Laparoscopic hepatectomy for hepatic hemangioma is safe and feasibile with good effect under the condition of strict indication selection and experienced surgeons operating.

AIM To study the experimental therapeutic effects of iptakalim hydrochloride(Ipt) on hypertensive cardiac remodeling in spontaneously hypertensive rats(SHR) and stroke prone spontaneously hypertensive rats(SHRsp). METHODS SHR at the age of 12 week old were treated ig with lisinopril 12 mg?kg -1 ?d -1 or Ipt 3 mg?kg -1 ?d -1 , once a day for 30 days. Age matched Wistar rats were used as normal control. 10 week old SHRsp were treated ig with Ipt 0 25,1 0 and 4 0 mg?kg -1 , once a day for 12 weeks. Age matched Wistar rats were used as normal control. After killing animals, the effects of Ipt on hypertensive cardiac remodeling were investigated. RESULTS During the 4 week experimental period, the systolic blood pressure(SBP) and heart rates(HR) of the untreated SHR were increased progressively. Ipt 3 mg?kg -1 ?d -1 could decrease SBP effectively and inhibit the increasing tendency of HR. Ipt had no effects on hypertensive cardiac remodeling in SHR. Under the same experimental conditions, lisinopril 12 mg?kg -1 ?d -1 could decrease SBP effe-ctively and had no effects on HR. The hypertensive cardiac remodeling could be alleviated by lisinopril. During the 12 week experimental period, the SBP of the untreated SHRsp were increased progressively. Ipt 0 25,1 0 and 4 0 mg?kg -1 could decrease the SBP of SHRsp effectively. Ipt at the doses of 0 25 and 1 0 mg?kg -1 had no effects on heart rates. But in the 4th week after administration of Ipt 4 0 mg?kg -1 , significant decrease in heart rates was observed. Compared with Wistar rats, the weight of left ventricle and septum(LV+S) and the ratio of LV+S to body weight(LV+S/BW) in untreated SHRsp were elevated significantly. Ipt 0 25, 1 0 and 4 0 mg?kg -1 ?d -1 could decrease LV+S and LV+S/BW significantly. CONCLUSION Ipt could decrease SBP of SHR and SHRsp effectively. The effects of Ipt on hypertensive cardiac remodeling were related with the experimental therapeutic period. After having been treated with Ipt for 4 weeks, the hypertensive cardiac remodeling could not be reversed. But after having been treated with Ipt for 12 weeks, the hypertensive cardiac remodeling could be reversed significantly.

AIM To investigate the effects of iptakalim hydrochloride(Ipt) on the association and dissociation kinetic processes of [ 3H]glibenclamide(Gli) binding with sulfonylurea receptor(SUR 2B ) of ATP sensitive potassium channel (K ATP ) in vascular smooth muscles derived from Wistar rats,and to compare the properties of Ipt with those of nucleotides. The interactions between Ipt and nucleotides were also determined. METHODS The experiments of the association and dissociation kinetic processes of K ATP blocker[ 3H]Gli binding with endothelium denuded aorta smooth muscles were used. RESRLTS (1)The specific bindings of[ 3H]Gli with SUR 2B were not displaced by Ipt at the concentrations of 10 pmol?L -1 ～ 0 5 mmol?L 1 . Ipt 100 ?mol?L -1 retarded the association kinetic process and accelerated the dissociation kinetic process of [ 3H]Gli binding with SUR 2B . (2)Opposite to Ipt, ATP 1 mmol?L -1 accelerated the association kinetic process and retarded the dissociation kinetic process of [ 3H]Gli binding with SUR 2B There was an interaction between ATP and Ipt in the modulation of [ 3H]Gli binding with SUR 2B . (3) Similar with Ipt, ADP 1 mmol?L -1 retarded the association kinetic process and accelerated the dissociation kinetic process of [ 3H]Gli binding with SUR 2B , there was an interaction between ADP and Ipt in the modulation of [ 3H]Gli binding with SUR 2B . (4)Different from ATP and ADP, UDP had no effect on the association and dissociation kinetic process of [ 3H]Gli binding with SUR 2B . And there was not interaction between UDP and Ipt. CONCLUSION Ipt had no affinity with the binding sites of K ATP blocker in SUR 2B , but had negative allosterical modulation on it. The modulatory properties of Ipt were opposite to those of ATP, similar with those of ADP and different from those of UDP. There were interactions between ATP, ADP and Ipt in the modulation of [ 3H]Gli binding with SUR 2B , but there was not interaction between UDP and Ipt.

Aim To investigate the effect of iptakalim on neonatal cardiomyocytes hypertrophy induced by isoprenaline(ISO).Methods Hypertrophy in neonatal rat cardiac myocytes was established via culture with ISO.Total protein content was measured by Lowrys method.The fluorescence intensity of intracellular Ca2+ was detected respectively with Fluo-3/AM loading by the laser confocal microscopy.Results ① 1?10-5mol?L-1 ISO can activated ?-AR completely;② the total protein of cardiomyocytes and intracellular i was markedly decreased by treatment with IPT and represented a dose-dependent manner.Conclusion IPT could inhibit the increase of protein content of cardiomyocytes induced by ISO,which may be contributed to the decease of intracellular Ca2+ concentration.

Objective To evaluate the treatment effects of the olecranon comminuted fracture by the angle stability prin-ciple combined with support under the articular surface. Methods From November 2008 to June 2012, 13 patients (7 male and 6 female, aged from 20 to 77 years) suffered from olecranon comminuted fracture were treated with Synthes anatomy locking com-pression plate and screws combined with Kirschner wires supporting under the articular surface through the posterior median ap-proach. Fractures occurred in the left elbow in 9 and in the right elbow in 4. According to the Mayo classification, 11 cases were classified as Mayo type IIB and 2 as IIIB. According to the Schatzker-Schmeling classification, 2 fractures were type A2, 9 type C, and 2 type D. One patient with type C fracture also had type I coronoid fracture according to Regan and Morrey classification. The Mayo elbow performance index (MEPI) and the shortened disabilities of the arm shoulder and hand (Quick-DASH) were employed to evaluate the functions. All patients took the satisfaction survey and X-ray during the follow-up. Results All patients were fol-lowed-up for 8 to 41 months. The mean ROM of the elbow joint was 112° (range, 65°-140° ), and the mean rotation angle of the forearm was 170° (range, 150°-180°). The mean score for the MEPI was 96 (range, 85-100), excellent 12, good 1. The mean score for the Quick-DASH was 6.2 (range, 0-16.7). In the satisfaction survey, 8 patients were very satisfied, 4 satisfied, 1 common level. All patients took the X-ray during the follow-up and all of them had achieved fracture union completely with the mean time period as 12.7 weeks (range, 11-24 weeks). No cubitus varus, valgus, and instability were found in all patients. No complication, such as infection, ulnar nerve injuries and etc. was found. Five patients complained about mild discomfort caused by internal fixation at 3 months after surgery. Three of them were diagnosed as joint stiffness because of ROM within 100° . One case in 3 elbow stiffness patients developed osteoarthritis after eight months, but no pain during joint activity. Internal fixation was removed in one case;an-other young patient took the operation for removal of internal fixation and release of medial ligament;the third patient refused oper-ation. Conclusion Angle stability principle (Synthes anatomy locking compression plate and screws) combined with supporting under the articular surface (Kirschner wires) can achieve stable fixation in treating olecranon comminuted fracture. It may realize the early exercise of the elbow joint with excellent clinical results. Therefore, it may be an optional choice in clinical practice.
