Hepatic artery stricture (HAS) after liver transplantation can lead directly to transplanted liver function exhaustion and complications of biliary system. The early diagnosis and treatment are crucial for better prognosis. Doppler ultrasound is the first method of choice, and angiography can give further clear dignosis. The balloon dilatation is still effective for hepatic arterial stenosis. With the more adaptable usage of oronary stent, if possible, would reveal more promising result especially for tortuous stenotic hepatic artery. The vascular reconstruction or repeated liver transplantation is still the effective therapeutic methods.

A method for residual determination of 5 pyrethroid pesticides in Anoectochilus roxburghii by cloud point extraction-back extraction-GC-MS was established. PEG 6000 was used as extraction agent and isooctane was used for back-extractant. The con- tent was calculated by external standard method. The linear range was from 15 to 2 000 μg x kg(-1) with the good correlation coefficients (0.955-0.999). The recoveries at spiked concentrations of 50-500 μg x kg(-1) ranged from 85.12% to 101.6%. The limit of detection and quantification of 5 pyrethroid pesticides were in the range of 0.63-3.10 μg x kg(-1) and 2.10-10.31 μg x kg(-1), respectively. The proposed method can be applied to the determination of pyrethroid pesticides residues in A. roxburghii.

Objective To compare the effects and significance of laparoscopic and open D2 gastrectomy on the expression of interleukin (IL)-6 and IL-10.Methods The clinical data of 146 patients with gastric cancer who were admitted to the Southwest Hospital from November 2010 to October 2011 were prospectively analyzed.All the patients were randomly divided into the laparoscopic group (75 patients) and open group (71 patients)according to the sealed envelope method.Laparoscopic or open D2 gastrectomy were performed according to the 14th edition of gastric cancer treatment guidelines of Japan Gastric Cancer Association.Peritoneal lavage fluid was collected at the beginning and the end of operation,and the concentrations of IL-6 and IL-10 in the peritoneal lavage fluid were detected by enzyme linked immunosorbent assay.The measurement data were analyzed using the t test,and the count data were analyzed using the chi-square test.Results The preoperative concentrations of IL-6 in the laparoscopic group and the open group were (34 ± 13)μg/L and (35 ± 12)μg/L,respectively,with no significant difference between the 2 groups (t =-5.110,P ＞ 0.05).The postoperative concentrations of IL-6 in the laparoscopic group and the open group were (4015 ± 1592)μg/L and (6724 ± 2112)μg/L,respectively.The postoperative concentration of IL-6 in the laparoscopic group was significantly lower than that of the open group (t =-8.367,P ＜ 0.05),and the postoperative concentrations of IL-6 were significantly higher than those before operation in the laparoscopic group and open group (t =-59.065,-87.123,P ＜0.05).The preoperative concentrations of IL-10 in the laparoscopic group and the open group were (43 ±9) μg/L and (42 ± 10) μL,respectively,with no significant difference between the 2 groups (t =1.190,P ＞0.05).The postoperative concentrations of IL-10 in the laparoscopic group and the open group were (92 ± 32)μg/L and (62 ± 23)μg/L,respectively.The postoperative concentration of IL-10 was significantly higher than that of the open group (t =6.408,P ＜ 0.05),and the postoperative concentrations of IL-10 were significantly higher than those before operation in the laparoscopic group and the open group (t =-12.680,-6.802,P ＜ 0.05).Conclusion Peritoneal inflammatory reaction is relatively lighter after laparoscopic D2 gastrectomy when compared with open D2 gastrectomy,which might prevent the peritoneal metastasis of gastric cancer mediated by IL-6.

Objective To investigate the sensitivity and variability factors that were assessed on the forced swimming test (FST) using BALB/C and Kunming mice. Methods The immobility time of FST was compared using Kunming and BALB/C mice in different experimental conditions including circadian rhythm ( day and night) ,gender and water temperature ( 12,22 and 32℃ ) . Results (①) The immobility time of BALB/C during the daytime( ( 142.42 ± 33.58) s) was significantly increased than that at night ( ( 104.89 ± 34.33 ) s). (② The immobility time of Kunming mice( (91.95 ± 40.32) s) was significantly decreased than that of BALB/C mice ( ( 142.42 ± 33.58 ) s). (③)The immobility time under the water temperature of 22 C ( ( 92.24 ± 25.81 ) s) was significant longer than that under the water temperature of 32C ( (60.72 ± 11.11 ) s). Conclusion BALB/C stain,male mice,daytime and water temperature of 22℃ should be chosen in the FST.

Objective To investigate the clinical value of a new anvil inserting method for esophagogastrostomy or esophagojejunostomy during laparoscopic radical proximal gastrectomy or radical total gastrectomy for gastric cancer.Methods The clinical data of 21 patients with gastric cancer who received laparoscopic radical proximal gastrectomy or radical total gastrectomy at the Southwest Hospital from March 2010 to February 2011 were retrospectively analyzed.Five trocars were inserted through the abdominal wall of the patients.After perigastric lymphadenectomy and mobilization of esophagus,an incision was made on the esophagus above the tumor,and then the anvil with drawn wire attached was inserted into the esophagus.An endo-cutter was applied to cut the esophagus adjacent to the incision left the drawn wire untouched,and then the stem of the anvil was pulled out by the drawn wire for laparoscopic anastomosis. Results The operations were successfully accomplished under the laparoscope with no conversion to open surgery.Fifteen patients received laparoscopic radical total gastrectomy and 6 received laparoscopic radical proximal gastrectomy. The mean operation time,volume of blood loss,time to off-bed activity,passage of flatus and postoperative duration of hospital stay were (257 ± 38) minutes,( 119 ± 32) ml,(2.5 ± 0.5 ) days,( 3.7 ± 0.8 ) days and (7.5 ± 2.6) days,respectively.No perioperative mortality,anastomotic bleeding or anastomotic fistula was detected.One patient was complicated with pulmonary infection + pleural effusion and was cured by conservative treatment; 1 was complicated with anastomotic stenosis which was alleviated by gastroscopic balloon dilation; 1 was complicated by incisional infection and was cured by medical treatment after drainage.No cancer cells were detected at the anastomotic ring or resection margin of the specimen.There were 4 patients with well-differentiated adenoma,8 with moderate-differentiated adenoma and 9 with poor-differentiated mucinous adenoma.There were 5 patients in stage Ⅰ,10 in stage Ⅱ and 6 in stage Ⅲ (UICC staging).Twenty-one patients were followed up for a mean period of (11 ±4) months (range,6-17 months ),no tumor recurrence or metastasis was detected. Conclusions The new technique for anvil insertion is safe,effective and easy for manipulation and learn.It offers a new approach for laparoscopic digestive tract reconstruction.

Although the surgical procedure and approach of da Vinci robotic surgical system-assisted radical resection of gastric cancer are gradually mature,it is rarely used for the resection of gastric stump cancer because of the complexity and low resection rate.In November of 2012,resection of gastric stump cancer using da Vinci robotic surgical system was performed in the Southwest Hospital.The short-term efficacy was satisfactory after the follow-up for 12 months.Da vinci robotic surgical system has the advantages of clear vision,easy manipulation of abdominal adhesion detaching,flexible operation and stable traction during resection of gastric stump cancer.
