Objective To investigate the clinical effects of a modified splenocaval shunt combined with pericardial devascularization ( PCDV ) in the treatment of gastroesophageal variceal bleeding. Methods From 1997 to 2007, 168 patients with gastroesophageal variceal bleeding caused by portal hypertension were treated at the People's Hospital of Shaanxi Province. Among all the patients, 90 received a splenocaval shunt + PCDV(combined group) and the remaining 78 received PCDV (PCDV group). Changes in intra- and postoperative hemodynamics of the portal venous system were detected by Doppler color flow imaging, and free portal pressure was measured intraoperatively. All data were analysed using analysis of variance, the paired t test and chi-square test.Results The mortality was 3% (3/90) in the combined group and 5% (4/78) in the PCDV group, with no significant difference between the two groups (x2 = 0.038, P ＞0.05 ). The postoperative rebleeding rate was 6%(5/79) in the combined group, which was significantly lower than 13% (8/60) in the PCDV group (x2 =4.824,P ＜ 0.05 ). The incidence of hepatic encephalopathy was 6% (5/79) in the combined group and 7% (4/60) in the PCDV group, with no significant difference between the two groups ( x2 = 0.072, P ＞ 0.05 ). The 1-, 3-, 5-,and 10-year survival rates were 97% (77/79), 92% (55/60), 80% (16/20) and 60% (3/5) in the combined group, and 97% (58/60), 83% (40/48), 73% (22/30) and 53% (8/15) in the PCDV group, respecitvely,with no significant difference between the two groups ( x2 = 0.731, P ＞ 0.05 ). The intra- and postoperative portal pressures in the combined group were (38.8±4.2) cm H20 ( 1 cm H2O =0. 098 kPa) and (33.1 ± 1.5) cm H2O,with a significant difference ( t = 8. 574, P ＜ 0.05 ). The intra-and postoperative portal pressures in the PCDV group were (38.9±2.5) cm H2O and (34.6±2.6) cm H2O, with a significant difference (t =6. 530, P ＜0.05 ). There was also a significant difference in postoperative portal pressure between the two groups ( t = 2. 859,P ＜ 0.05 ). The intra-and postoperative diameters of the portal vein in the combined group were (1.40 ± 0.41 )cm and ( 1.22 ± 0. 15) cm, respectively, with a significant difference ( t = 2. 608, P ＜ 0.05 ). The intra-and postoperative portal venous flows in the combined group were (1280 ±350) ml/min and (830±360) ml/min, with a significant difference ( t = 5. 668, P ＜ 0. 05 ). The intra-and postoperative diameters of the portal vein in the PCDV group were ( 1.41 ±0.32) cm and ( 1.27 ±0.32) cm, respectively, with no significant difference between the two groups (t = 1. 637, P ＞ 0.05 ). The intra-and postoperative portal venous flows in the combined group were ( 1350 ± 380) ml/min and (980 ± 290) ml/min, with a significant difference ( t = 4. 096, P ＜ 0.05 ). There was no significant difference in postoperative portal venous flow between the two groups ( t = 1.871, P ＞ 0.05 ).Conclusions The modified splenocaval shunt combined with PCDV is safe and effective with a low rate of recurrent rebleeding. The clinical outcome and rational hemodynamic changes show that the combined procedure of splenocaval shunt and PCDV is a good choice for treatment of gastroesophageal variceal bleeding.

Objective To evaluate the effects,hemodynamies and hepatic functional reserve of a combined procedure of modified pmximal splenocaval shunt and pericardial devascularlzation (PCDV) in the treatment of portal hypertension.Methods From 1997 to 2007,a total of 255 patients with cirrhotic portal hypertension received combined (135 cases) or PCDV procedure (120 cases,) in our hospital.The clinical results were retrospectively analyzed.Changes of hemodynamics of the portal venous system were studied by Doppler color flow imaging and intraoperative free portal pressure (FPP) measurement.The hepatic functional reserve was evaluated by indocyanine green (ICG) retention ratio and functional hepatic flow(FHF).Results Postoperative mortality was 2.2% in combined group and 4.3% in PCDV group.The long term rebleeding rate was 5.5%as revealed by follow-up in combined group,which was significantly lower than that in PCDV group of 14.1%(P<0.05).The incidence of encephalopathy was 6.4%and 5.4%in combined group and PCDV group respectively(P>0.05).The 1-,3-,5-and 10 year-survival rates were 96.4%,90.0%,81.3%and 62.5% in combined group and 95.7%,86.7%,75.0%,57.1%in PCDV group.In combined group,the FPP、PVF and FHFwere(32.0±1.5)cm H_2O、(880±260)ml/min and(430±1 80)ml/min respectively,a significant decrease when compared with preoperative parameters (P<0.05),while R_(15) (30%±4%)increased (P<0.01).The similar results were observed in PCDV group postoperatively (P<0.05).Compared to PCDV group,the decrease of FPP in combined group was more significant(P<0.05),but the PVF,FHF and R_(15) were not significantly different (P>0.05).Conclusions The combined procedure is safe and effective in treatment of portal hypertension with better clinical outcome,moderate homodynamic changes and good maintenance of hepatic functional reserve.

Objective To investigate the effect of di-(2-ethylhexyl) phthalate (DEHP) on the postnatal lung development in newborn rats.Methods A total of 60 newborn Sprague-Dawley rats (weighing 5.0-8.0 g) in five age groups were studied in the first experiment.The rats were divided based on the different postnatal ages:postnatal day (PND)I,PND4,PND7 and PND14.A total of 45 newborn Sprague-Dawley rats (weighing 5.0-8.0 g) were randomly divided into three groups according to the dosage of DEHP administered in the second experiment.The newborn rats were administered DEHP through intraperitoneal injection at 10 (low-dose subgroup),100 (medium-dose subgroup) or 750 (high-dose subgroup) mg/kg daily from PND1 to PND13.The rats were sacrificed on PND14.Pups were sacrificed with lethal dose injection of pentobarbital sodium.The lung was removed.The right middle lobes were used for analysis.The tissue was processed for histology and lung sections were stained with HE for light microscopic (LM) morphometric measurement.The analysis was performed by means of a digital image analysis system,including pulmonary interstitial area ratio (IAR) and total length density of all segments.One-way ANOVA,LSD and Dunnet T3 methods were used for statistical analysis.Results In the normal controls,IAR decreased significantly by (31.97±5.03) ％,(30.05±3.57)％,(25.33± 1.83)％ and(22.01 ±2.19)％,respectively,from PND1 to PND14 (P＜0.05 or P＜0.01).IAR in medium-and high-dose subgroups increased significantly by (24.11 ±2.78)％ and (26.53± 3.42)％,respectively on PND 14.The total length density of all segments in unit area lung volume increased significantly by 0.047 8±0.003 7,0.050 0±0.002 9,0.071 2±0.003 0 and 0.084 4±0.004 3,respectively from PND1 to PND14 (P＜0.01).In the DEHP treated animals,when compared with the control group,IAR was significantly higher on PND14 (P＜0.05 or P＜0.01),while the total length density of all segments in unit area lung volume was significantly decreased (P＜0.05 or P＜0.01).Length density in medium-and high-dose subgroups were higher than that of low-dose subgroup by 0.082 9±0.001 8,0.077 2±0.002 0 and 0.071 3±0.003 7,respectively on PND14 (P＜0.05 or P＜0.01).Conclusions Medium-and high-dose DEHP affect the postnatal lung development in rats in a dose-dependent mode.

With the increasing prevalence rate of nonalcoholic fatty liver disease (NAFLD), this disease has been taken more seriously, more and more studies have been carried out in this field, and some important progress has been made. This article introduces the important research findings in the epidemiology, risk factors, pathogenesis, noninvasive diagnosis, and treatment of NAFLD, as well as related liver cirrhosis and hepatocellular carcinoma in China within the past five years, in order to know the current status of related research. This article points out that there still exists a certain gap between related clinical and basic research in China and the rest of the world, especially in the public's perception and the medical workers′ emphasis on NAFLD. In the future, the research on epidemiology, pathogenesis, patient management, and drug therapies should be enhanced.

ObjectiveTo systematically review the clinical effect of glucocorticoids used alone or in combination with pentoxifylline in patients with severe alcoholic liver disease. MethodsPubMed, Embase, Chinese Scientific Journal Full-Text Database, CBM, China Scientific Journal Database, and Chinese Medical Association Digital Journal Database were searched for related articles published up to November 2018, and related journals and collected papers from conferences were searched manually. The clinical effect of glucocorticoids versus placebo, glucocorticoids versus pentoxifylline, and glucocorticoids combined with glucocorticoids versus glucocorticoids alone was analyzed. The effect of glucocorticoids and pentoxifylline used alone or in combination on 28-day survival rate and hepatorenal syndrome in patients with severe alcoholic liver disease was assessed. Odds ratio (OR) and 95% confidence interval (CI) were used to evaluate outcome indicators. RevMan 5.3 software was used for data analysis. ResultsA total of 22 studies were included, with 1956 patients in total. The glucocorticoid group had a significantly lower 28-day mortality rate than the control group (25.12% vs 30.67%, OR=0.71, 95%CI: 0.55-0.93, P=0.01). Subgroup analysis showed that there was a significant difference in 28-day mortality rate between the glucocorticoid group and the pentoxifylline group (OR=0.68, 95%CI: 0.48-0.97, P=0.03), while there was no significant difference between the glucocorticoid+pentoxifylline group and the glucocorticoid group (OR=0.92, 95%CI: 0.66-1.29, P=0.64). Compared with the glucocorticoid group, the glucocorticoid+pentoxifylline group had a significantly lower incidence rate of hepatorenal syndrome (3.94% vs 803%, OR=0.45, 95%CI: 0.24-0.83, P=0.01). Funnel plots showed no publication bias. ConclusionGlucocorticoids combined with pentoxifylline can reduce the incidence rate of hepatorenal syndrome in patients with severe alcoholic liver disease.

Objective To discuss the safety and efficacy of inserting ureterovesical reimplantation by means of laparoscopy associated with six-stitch suture.Methods There was an retrospective analysis on operation videos and clinical data for 16 participants of inserting ureterovesical reimplantation by means of laparoscopy associated with six-stitch suture with the period from March in 2012 to September in 2015. And these were statistically analyzed including the operation time, intraoperative bleeding volume, postoperative drainage volume, removal time of drainage tube, admission time after operation and the incidence of postoperative complications of vesicoureteric reflux and stenosis.Results The operations of 16 participants were completed successfully without converting to open surgery. The operation time was 60 ~ 125 min (Mean time: 85 min); intraoperative bleeding volume was 20 ~ 50 ml (Mean volume: 32 ml); postoperative drainage volume was 60 ~ 400 ml (Mean volume: 106 ml); removal time of drainage tube was 3 ~ 6 d (Mean time: 4.2 d) and admission time after operation was 7 ~ 10 d (Mean time: 8.5 d). There was the follow-up with 6 ~ 18 months (Mean time: 12 months) for participants. No anastomotic stenosis was present. In addition, one participant was suffered from mild vesicoureteric relfux. And there was no aggravation during 18 months.Conclusions The inserting ureterovesical reimplantation by means of laparoscopy associated with six-stitch suture was safe and effective. It was found that the operation time was significantly shortened and the incidence of postoperative complications of vesicoureteric relfux and anastomotic stenosis was not increased. By contrast, the six-stitch suture could reduce the incidence of anastomotic stenosis.
