Objective To evaluate left liver anatomical resection via left vertical groove by laparoscope.Method Among 103 patients with left intrahepatic biliary calculi,39 cases underwent left lateral hepatectomy,20 cases did left liver anatomical resection via left vertical groove by laparoscope,29 cases underwent left lateral hepatectomy via left liver diaphragmatic surface,15 cases did left liver anatomical resection via the first porta.Result In the 103 cases of laparoscopic left liver anatomical resection,101 cases were successful and two cases were conversed to open surgery.In the success group,total laparoscopic anatomical left lateral lobectomy was performed (Ⅱ,Ⅲ section) in 68 cases.Compared with the approach via left liver falciform ligament diaphragmatic surface,the operatve time via left vertical groove was significantly shorter(t =-2.723,P =0.008,intraoperative blood loss was significantly smaller (t =-5.399,P =0.000),while the differences in postoperative hospital stay (t =-0.168,P =0.867) and postoperative complications (x2 =0.664,P =0.415) were of no statistical significance between the 2 groups.In the 33 cases of left hemihepatectomy (Ⅱ,Ⅲ,Ⅳ section),those performed via left vertical groove compared with through the first porta hepatic,used shorter operation time(t =-3.144,P =0.004),while blood loss was similar(t =-1.049,P =0.302),as well as the length of hospital stay(t =0.784,P =0.439).There was no postoperative bleeding and intractable bile leakage,nor postoperative air embolism.Flatus on an average of (2.5 ± 1.2) days.Patients were discharged from hospital 5-17 (9.98 ±2.98) days post-op.96 cases were followed up in the 101 cases undergoing successful total laparoscopic left hemihepatectomy.The followed-up time were 3-52 (32.6 ± 5.7) months.Postoperative review found no residue stone.One case in first porta hepatis group,caudate lobe atrophy was found by postoperative CT.Conclusions Left liver anatomical resection via left vertical groove by laparoscope is less traumatic,quick recovery with satisfactory clinical curative effect for the treatment of left hepatolithiasis.

Four Polystictus Versicolor PVC0? PVC1? PVC2 ?PVC3 were examined for their decolorization ability to simulative refinery effluents and biodegradation ability to HADP'S, Melanoidin, Caramel The effect of effluent colorants on the yield of four Polystictus Versicolor biomass and mycelium polysaccarride(PSK) was also studied PVC0 showed the best decolorization ability and the high biomass; although the PSK content of PVC0 is less than PVC1, its yield of mycelium PSK is the highest Chosen PVC0 as the research strain The result showed that the rate of decolorization of PVC0 to 75% concentration real refinery effluents is 53% Which is less than to the simulative refinery effluent decolorization rate 71% Real refinery effluents and simulative refinery effluent has the same PVC0 biomass and PSK yield

Objective To investigate the effect of peripheral blood MDC on predicting adverse cardiac events of patients with acute STEMI. Methods Thirty-nine patients with acute ST segment elevation myocardial infarction admitted in the People′s Hospital of Deyang from February 2016 to August 2017 were selected by random sampling. According to 7-day adverse cardiac events, the patients were divided into non-combination adverse cardiac events group (uncomMI group, 23 patients) and combination adverse cardiac events group (comMI group, 16 patients), and 24 healthy persons were selected as normal control group. The general situation, clinical characteristics and MDC, PDC, analysis of uncomMI group and comMI group in the 1st and 3rd day after the onset of acute ST segment elevation myocardial infarction was compared. Factors influencing adverse cardiac events in patients with acute ST segment elevation myocardial infarction were analyzed. Results The peripheral blood MDC and plasmacytoid dendritic cell (PDC) counts in patients with STEMI were significantly lower than those in normal controls in early time(at the time of day 1)(P<0.05), but the peripheral blood MDC and PDC counts in uncomMI group was not significantly different from that in normal control group at the time of day 3 (P>0.05). The peripheral blood MDC and PDC counts in comMI group were lower than those in uncomMI group and control group. The Logistic analysis showed that the elderly patients, total cholesterol (TC), MDC (at the time of day 3) were all risk factors of 7-day adverse cardiac events (P < 0.05). The receiver operating characteristic (ROC) results showed that the maximum area under curve(AUC) was 0.8286 when the MDC truncation point was 7 mg/L, and the sensitivity was 80.0% and the specificity was 85.7% . Conclusions For STEMI patients, MDC of peripheral blood is associated with 7-day adverse cardiac events. The percentage of MDC in peripheral blood of patients with acute STEMI has a certain clinical value in the diagnosis of 7-day adverse cardiac events. In addition, elderly patients with STEMI have an increased risk of 7-day adverse cardiac events.

Objective To evaluate laparoscopic right hepatectomy through the right incisura or the right groove for hepatic benign disease.Methods This study enrolled 32 patients of hepatic benign lesions within the right lobe of the liver including hepatic hemangioma (n =7),hepatic focal nodular hyperplasia (n =2),right intra-hepatic bile duct stones (n =23) with concomitant extra-hepatic bile duct stones in 19 cases.Results Laparoscopic procedures were successful in 28 patients,while 4 patients were converted to laparotomy.Time of operation was 235 to 405 min,time for right hemihepatectomy was (305 ±41) min on average.Time for right hemihepatectomy and biliary tract exploration and removal of stones was (326 ± 48)min on average.The intraoperative blood loss was (573 ±219) ml on average.On postoperative follow-up,patients with hepatic hemangioma and focal nodular hyperplasia had no residual lesions.2 cases suffered calculus residue,residual stones were removed by repeat choledochoscopy with primary stones clearence rate of 91.3% (21/23).Bile leakage occurred in 3 cases and pleural effusion in 7 cases.The gastrointestinal function recovered (2.8 ± 0.71) days after surgery.The hospital stay was (11.5 ± 2.98) days.28 patients were followed up for (32 ± 8) months.Conclusion The laparoscopic anatomical right hemihepatectomy through the right incisura or the right groove is a satisfactory surgical procedure.
