Objective To evaluate the result of multiple segmentectomy under selective occlusion of hepatic inflow for complicated intrahepatic cholangiolithiasis. Methods In this study 12 cases of complicated intrahepatic cholangiolithiasis receiving multiple segmentectomy under selective occlusion of hepatic inflow during 2004. 1 - 2010. 10 were reviewed retrospectively. The short-term and long-term outcomes of the patients were analyzed. Results There was no surgical mortality in this group. The segmentectomy performed were Ⅱ + Ⅲ + Ⅴ in 1 case; Ⅱ + Ⅲ + Ⅵ in 2 cases; Ⅱ + Ⅲ + Ⅴ + Ⅵ in 1 case;Ⅱ +Ⅲ+Ⅵ +Ⅶ in4 cases; Ⅱ +Ⅲ +Ⅳ +Ⅵ in 3 cases and Ⅱ + Ⅲ +Ⅳ +Ⅵ +Ⅶ in 1 case. The average intraoperative blood loss was 560 ± 291 ml. Postoperative complications were wound infection in 2 cases, bile leakage in 1 case, abdominal infection in 1 case. There were no liver failure, intrabdominal hemorrhage or hemobilia; stone clearance rate at 10 days after operation was 83% (10/12) and 92%(11/12) at 6 weeks after operation following postoperative choledochoscopic lithotripsy. 92% (11/12) cases were followed-up with the median follow-up period of 31 months. The result was excellent or good in 92% (11/12) cases. Conclusions Multiple segmentectomy was the choice for complicated intrahepatic cholangiolithasis, and the procedure could be safely performed under selective occlusion of the hepatic inflow.

Objective To evaluate right hepatic veins exclusion in the prevention of massive bleeding and air embolism during the resection of huge hepatic cavernous hemangioma near the second hepatic portal. Method This is a retrospective study on the clinical data of 12 hepatic hemangioma patients at the Live Surgery Department of Zhejiang Provincial People's Hospital from 2004. 1 to 2010.3. In all patients the huge hepatic cavernous hemangioma was adjoining the second hepatic portal. Block webbing or vascular clamp were used to exclude the right hepatic veins. Among the 11 patients without hepatic cirrhosis Pringle maneuvre was applied in 5 cases and selective hepatic inflow occlusion in 6 cases. Patients with hepatic cirrhosis used hemi-hepatic blood inflow occlusion. Results During the surgery no rupture of right hepatic vein happened. Nine patients used vascular block webbing and 3 patients used vascular clamp.Six patients without cirrhosis used the complete hepatic inflow occlusion and other patients without cirrhosis used hemi-hepatic blood inflow occlusion. Cirrhotic patients used hemi-hepatic blood inflow occlusion. All the operations were successful. Intraoperative blood loss ranged from 200 - 5800 ml, averaging 680 ml. Three patients needed not blood transfusion. There was no right hepatic vein rupture or air embolism. Conclusion Right hepatic veins exclusion is a useful technique to prevent massive bleeding and air embolism caused by the rupture of right hepatic vein during the resection of huge hepatic cavernous hemangioma.

Objective To evaluate the clinical efficacy of emergent endoscopic injection of tissue adhesive (N-oclyl-a-cyanoacrylate) combined with endoscopic variceal ligation (EVL) for esophageal and gastric varices bleeding. Methods Data of 21 patients with acute esophageal and gastric varices bleeding who received emergent endoscopic injection of tissue adhesive and EVL were retrospectively studied. Results The instant hemostatic rate was 95% (20/21) with no severe complications. Conclusion Emergent endoscopic injection of tissue adhesive combined with EVL is an effective and safe therapy for esophageal and gastric varices bleeding.

Objective To evaluate hepatic vein exclusion (HVE) outside the liver in the resection of giant hepatic hemangioma near the second hepatic hilum. Methods From January 2003 to December 2009, giant hepatic hemangiomas near the second hepatic hilum were resected in 19 cases. Preoperatively 19 cases were divided into two groups: HVE group (9 cases) and IVE group ( 10 cases). Data regarding the intra-operative and postoperative courses of the patients were analyzed. Results There was no difference between the 2 groups regarding the age, sex and tumor size. No damage of hepatic vein was happened in HVE group. Resection of the hemangioma was applied in all cases of HVE group, and 1 case in IVE group had right hemi-hepatectomy. Hepatic veins rupture occurred in 4 cases in IVE group and 2 cases of them had massive bleeding, while in HVE group hepatic veins rupture occurred in 5 cases but no massive bleeding occurred. Intra-operative blood loss was significantly less in HVE group than IVE group. The serum ALT value in postoperative day 1 and total bilirubin in postoperative day 3 in HVE group was significantly lower than that of the IVE group. The mean drainage volume in HVE group was significantly less than that of the IVE group on postoperative day 1 and day 2. The total cost of patient in HVE group were significant less than in IVE group. Conclusions The use of hepatic vein exclusion reduces the risk in the resection of giant hepatic hemangioma near the second hepatic hilum.

Objective To evaluate the effect of BML?111 on ventilator?induced lung injury in rats. Methods Forty?eight healthy male Sprague?Dawley rats, weighing 200-250 g, aged 6-8 weeks, were randomized into 6 groups ( n=8 each) using a random number table: control group ( C group) , low tidal volume (VT) group (LVTgroup), high VT group (HVTgroup), low dose BML?111 group (BL group), high dose BML?111 group ( BH group) , and BML?111 plus BOC?2 ( lipoxin A4 receptor antagonist) group ( BOC?2 group) . Group C kept spontaneous breathing after tracheotomy, and received no mechanical venti?lation. The rats in the other 5 groups were mechanically ventilated ( respiratory rate 80 breaths∕min, frac? tion of inspired oxygen 21%, positive end?expiratory pressure 0) . The VT was 6 ml∕kg in group LVT , or 20 ml∕kg in HVT, BL, BH and BOC?2 groups. BML?111 0?1 and 1?0 mg∕kg were injected intraperitoneally during ventilation in BL and BH groups, respectively. In group BOC?2, BOC?2 50 μg∕kg was injected in?traperitoneally before ventilation, and BML?111 1?0 mg∕kg was injected intraperitoneally during ventilation. Arterial blood samples were collected at 4 h of ventilation, arterial oxygen partial pressure ( PaO2 ) was de?termined. Then animals were sacrificed by exsanguination. Bronchoalveolar lavage fluid ( BALF) of the left lung was collected for determination of neutrophil count, and the level of neutrophil was calculated. The right lung tissue specimens were obtained for microscopic examination, and for determination of wet∕dry lung weight ratio ( W∕D ratio ) , myeloperoxidase ( MPO ) activity, and contents of malondialdehyde ( MDA) , monocyte chemoattractant protein?1 ( MCP?1) , tumor necrosis factor?alpha ( TNF?α) , interleu?kin?1beta ( IL?1β) and IL?6. Results Compared with group C, PaO2 was significantly decreased, and the level of neutrophil in BALF, W∕D ratio, MPO activity, and contents of MDA, MCP?1, TNF?α, IL?1β and IL?6 were increased in group HVT ( P<0?05) , and no significant change was found in the variables mentioned above in group LVT ( P>0?05) . Compared with group HVT , PaO2 was significantly increased, and the level of neutrophil in BALF, W∕D ratio, MPO activity, and contents of MDA, MCP?1, TNF?α, IL?1β and IL?6 were decreased in group BH, and the contents of TNF?α, IL?1βand IL?6 were significantly decreased ( P<0?05) , and no significant change was found in the other variables in group BL ( P>0?05) . Compared with group BH, PaO2 was significantly decreased, and the level of neutrophil in BALF, W∕D ratio, MPO activity, and contents of MDA, MCP?1, TNF?α, IL?1β and IL?6 were increased in group BOC?2 (P<0?05). The pathological changes were significantly attenuated in group BL as compared with HVT and BOC?2 groups. Conclusion BML?111 can attenuate ventilator?induced lung injury in rats, and activated lipoxin A4 receptors are involved in the mechanism.

Objective To explore the feasibility and safety of laparoscopic right hemihepatectomy (LRH) via anterior approach for larger tumors in the right lobe of the liver.Methods A retrospective study was conducted based on the clinical data of ten consecutive patients with large right liver cancer undergoing LRH through anterior approach and thirty-seven patients undergoing open hemihepatectomy by anterior approach in recent 6 years.Results Between the two groups there were no significant difference in gender,average age,the mean tumor size,preoperative liver reserve function,cut margin and intraoperative blood transfusion.The LRH group had less average intraoperative blood loss [(408 ± 158)ml vs.(520 ± 153)ml,t =2.047,P =0.046] and shorter postoperative hospital stay [(11.5 ±2.8)d vs.(16.2 ±4.6) d,t=3.091,P=0.003],longer operation time [(302 ±38)min vs.(251±55)min,t=2.732,P=0.009].There was no perioperative death and no significant difference in complications (20.0％ vs.35.1％,x2 =0.812,P =0.367) and similar median survival time (36 mon vs.29 mon,x2 =1.266,P =0.261).Conclusions LRH via anterior approach for larger tumors in the right lobe of the liver is safe and feasible.

Objective To understand the situation of downward dislocation of intrauterine device (IUD) and the impact related to the effectiveness of IUD use, in China. Methods An epidemiological survey with cross-sectional, retrospective and prospective study designs was conducted to investigate 18 922 IUD users who were selected by a multi-phase stratified cluster sampling method. Results IUD's downward dislocation had been an important unsuccessful issue related to the IUD insertion that accounted for 20% of total the cases of failure. The top three failure outcomes would include extrusion,removal due to downward dislocation and unintended pregnancy. Respectively, the cumulative rates and the ranking due to IUD failure (per 100 women) in the first, third, sixth and twelfth month were shown as follows: extrusion appeared as 0.33%, 1.13%, 2.21% and 4.30%; removal as 0.10%, 0.37%, 0.80% and 2.34% ; while unintended pregnancy were 0.03%, 0.14%, 0.41% and 1.14%. Conclusion IUD' s downward dislocation made great impact on the effectiveness of IUD use that should call for attention from relative governmental sectors and researchers in the areas of prevention, diagnosis and treatment.

OBJECTIVE: To investigate the level of mRNA expression of C-reactive proteins (CRP) induced by LPS in human alveolar type epithelial cell line, A549. METHODS: Sputum and plasma specimens were obtained from patients with chronic obstructive pulmonary disease (COPD) diagnosed according to the national criteria. CRP was measured by enzyme-linked immunosorbent assays (ELISA). A549 cells were incubated with lipopolysaccharide (LPS) at different concentrations and for different time. CRP mRNA was extracted from cells and the expression was analyzed by RT-PCR. The CRP in the supernatant was measured by ELISA. RESULTS: The concentration of CRP in the sputum of patients with COPD was significantly higher than that in the plasma (P < 0.05). LPS at different concentrations and for different time induced the expression and secretion of CRP in A549 with a time-dependent increase and the expression of CRP were significantly higher than those of the control (P < 0.05 - 0.01). CONCLUSION Self-secretion of CRP in the respiratory tract may exist. A549 induced by LPS may express CRP mRNA.

The stability of melittin in different solvents (water, deoxygenated water, physiological saline, PBS, 50% ethanol, ethanol, glycerol)was studied and the results showed that the stability of melittin is not influenced by light, temperature and pH in 50% ethanol, which melittin can be completed dissolved when compared with ethanol and glycerol, in such, 50% ethanol was chosen as solvent storage when measured content of melittin. Then the effect of different concentrations of PBS, the pH of PBS and rat skin ho- mogenates were tested, and the results showed that melittin was degraded rapidly at low concentration solution and low ionic strength. Increasing pH of PBS and rat skin homogenate can accelerate the degradation of melittin. These researches provide an experimental ba- sis for further study of melittin.
