Objective: To determine oleanolic acid in Fructus Mume. Methods: HPLC with Shim-pack CLC-ODS column was used. The mobile phase was composed of MeOH-H 2O-HOAc-TEA (85∶15∶0.04∶0.02). The flow rate was 0.8mL?min -1 and the detection wavelength was at 204nm. Results: It showed that a good linear relationship existed in the range of 0.8864～4.432?g of oleanolic acid. Its average recovery was 97.03%. RSD was 0.25% (n=5), respectively. Conclusion: This method is quick, accurate and can be used for the determination of oleanolic acid of Fructus Mume.

Objective To study the preventive effects of selective bile ductal cannulation using an aqua-coat tipped Metro tracer guidewire on pancreatitis and hyperamylasemia after ERCP. Methods A total of 291 patients with biliary disease were enrolled in the study. The patients were randomized into the guidewire group (n= 149) and the control group (n= 142). In the guidewire group, the bile duct was first accessed by insertion of an aqua-coat tipped Metro tracer (diameter 0. 029 inch) guidewire through a 5.5Fdouble channel ERCP-tube to judge the bile duct by the direction of guidewire. As soon as cannulation was accomplished, the guidewire was removed to allow injection of contrast medium and other therapeutic manipulation. In the control group, the bile duct was opacified by the traditional method of cannulation of the biliary tree followed by single ERCP-tube cannulation, judgment of the bile duct by injection of contrast medium and performance of other therapeutic procedures. The incidences of post-ERCP pancreatitis and hyperamylasemia were compared between the 2 groups. Results The selective bile ductal cannulation was successfully conducted in 145 patients in the guidewire group and 138 in the control group. The incidences of post-ERCP pancreatitis and hyperamylasemia were significantly lower in the guidewire group than in the control group. Pancreatitis tended to be less severe for patients in the guidewire group. Conclusion Using the Double-Crossing method in selective bile ductal cannulation with an aqua-coat tipped Metro tracer guidewire reduced not only the frequencies of post-ERCP pancreatitis and hyperamylasemia but also the severity of post-ERCP pancreatitis.

HIS constitutes part of the technical support and infrastructure indispensable for the running of a modemized hospital. At present, more than 50% of hospitals at or above prefecture and city levels in China have set up HIS. However, because of the lack of reliability of facilities and man-made factors, HIS is apt to break down, which greatly hinders the normai activities of the hospital. The authors argue that wriat affects outpatient service the most in case of a network failure is the charging subsystem for outpatient service and thus offer an emergency charging plan for outpatient service as well as a method for putting it into effect. The workstation in charge of charging regularly downloads relative data on charging for outpatient service from the netvvork, and in case of a netvvork failure, the stan-dalone computer takes over, and when the network retums to normal, the computer then uploads the data it collected during the failure period to the database server, thus ensuring the integrity of the data.

OBJECTIVETo study the ischemic times of the main artery injury in the limbs and the influence on the limbs survival rate, and to analyze the reasons for the formation of the ischemia time.

METHODSFrom June 1996 to November 2012, 83 patients with completely severed limb main artery treated in our hospital were retrospectively studied. There were 77 males and 6 females, including 81 adults (ranging in age from 16 to 52 years old, with a median age of 35 years old) and 2 children (4 and 5 years old respectively). Seventy-five patients were treated with end to end anastomosis, 7 patients were treated with great saphenous vein transplantation, and 1 patient was treated with artificial blood vessel transplantation. The prior to admission ischemia time, after admission ischemia time and total ischemia time for successful and unsuccessful patients, as well as the causes of the formation of the ischemia time were studied. Limb survival rate of different ischemic time was counted. Sharpness injury or blunt injury ischemia time and amputation rate were researched statistically. All data were analyzed using SPSS statistical software.

RESULTSThere were 72 limbs survived, 11 amputated. The average ischemia time was (7.45±5.94) h for limb-salvage group and (13.73±14.00) h for amputation group. Prior to admission ischemia time between amputation and limb-salvage group had no significant difference. After admission the ischemia time in amputation group was longer than limb-salvage group. The amputation rate for ischemia time 21 to 44 h group was higher than other three groups (≤ 5 h, 6 to 10 h, 11 to 20 h) (P=0.023, 0.038, 0.044). Amputation reasons can be divided into anastomosis failure in the operation, vascular thrombosis 2 to 4 days after operation and late infection.

CONCLUSIONVascular injury limbs can tolerate longer ischemia time and the limb salvage succeed. Only too long ischemia time (> 20 h), limb amputation rate increases significantly. The main cause of long time ischemia is delayed diagnosis in the hospital. Whether limb-salvage success mainly depends on the degree of trauma and the quality of the anastomosis than ischemia time.

OBJECTIVETo study the influence of actual defect length and gap width of the limbs main artery on the method selection of repairing and reconstruction.

METHODSRetrospective study was carried out for 32 patients with extremity main artery injury from 1996 to 2009, including 30 males and 2 females; 30 adults with an average age of 36 years old ranging from 18 to 51 years, 2 children of 4 and 5 years old respectively. Injured body parts involved axillary artery in 4 cases,brachial artery in 7 cases,radial artery in 2 cases, femoral artery in 4 cases, popliteal artery in 13 cases, posterior tibial artery in 2 cases. Main arterial injury defect gap width of all cases were observed and the reasons were analyzed. All cases were repaired by the method of end to end anastomosis after vessels stretch.

RESULTSThe artery defect width was 3 cm to 7 cm with an average of (4.375 +/- 1.200) cm. Defect width of the upper extremity brachial artery and axillary artery group was (5.73 +/- 0.63) cm,the lower extremity femoral and popliteal artery group (3.80 +/- 0.73) cm, the posterior tibial artery group (3.25 +/- 0.35) cm, the radial artery group (3.00 +/- 0.00) cm. Defect width of upper extremity brachial artery and axillary artery group was larger than that of the other three groups (P < 0.01). End to end anastomosis was performed successfully in all cases. Blood supply recovered well. Because of the severe limb infection 2 patients had amputation in the late. All patients received follow-up. The patients without fracture were followed up to 2 weeks postoperatively, all patients with fractures were followed up to 1 year at least. Limb blood supply was good in all patients during the follow-up.

CONCLUSIONBlood vessel defect gap width is different from the actual vessel defect, but is larger than the actual vessel defect. Misjudgment of the vascular defect length will lead to more vascular transplantation. The vast majority of vascular defect can be directly repaired by the method of end to end anastomosis after the vessel free and stretch.
