An innovative approach,named associating liver partition and portal vein ligation for staged hepatectomy (ALPPS),has made possible a marked increase in future liver remnant (FLR) over a short period of time,and has challenged the concept of unresectability.To date,ALPPS has been employed for a variety of primary and metastatic liver tumors from many centers across the world.Many technical variations of ALPPS have been described.However,much controversy has surrounded this procedure,and many problems remain to be solved,such as the reasons for rapid hypertrophy,the technical feasibility,safety and long-term oncologic outcomes,and the result compared with the conventional two-stage hepatectomy.These aspects are needed to be evaluated further in large-scale studies.We believe that the ALPPS procedure will has much room for further development.

Objective To evaluate the risk factors of gallstone occurrence after gastrectomy for gastric cancer.Methods Relevant documents published from 1990 to 2014 were retrieved through Pubmed,Cochrane Library,Embase,Web of Science CNKI,Wan Fang and VIP databases search.The Meta-analysis was applied with RevMan 5.3 software for Odds ratio and 95％ CI.Results 24 studies were selected for this Meta-analysis which included 3 randomized controlled trials,13 cohort studies and 8 case-controlled studies.These 24 studies included patient number which ranged from 32 to 893.The pooled OR (95％ CI) and P values of OR (95 ％ CI) for physiologic digestive tract reconstruction were 0.53 (0.44 ～ 0.65,P ＜ 0.05) ;amount of resection of stomach,1.98 (1.29 ～ 3.04,P ＜ 0.05) ; lymphadenectomy,0.38 (0.21 ～ 0.72,P ＜ 0.05) ; vagotomy,0.24 (0.13 ～ 0.45,P ＜ 0.05) ; and pylorus preservation,0.70 (0.48 ～ 1.02,P ＞ 0.05).Conclusions Physiologic digestive tract reconstruction and vagus nerve preservation reduced occurrence of gallstones after gastrectomy.On the other hand,total gastrectomy and extensive lymph node dissection increased the occurrence.There was no significant difference in the occurrence of gallstones whether there was pylorus preservation or not.

Objective To explore the effect of oleanic acid on key enzyme activity in insulin-resistant HepG2 cells. Methods The HepG2 cells were divided into normal control,model control,metformin,and oleanic acid groups.Glycogen content in insulin-resistant HepG2 cell model were detected by hepatic glycogen test kit upon treatment with oleanic acid.Activities of glucokinase ( GK) ,phosphoenolpyruvate carboxylase kinase (PEPCK),and glucose-6-phosphatase (G-6-Pase) were assayed by the glucose 6-phosphate dehydrogenase coupling colorimetric, lactate dehydrogenase coupling colorimetric and ammonium molybdate constant phosphorus methods. Results The oleanic acid enhanced glucose consumption,lowered the activity of G-6-Pase and PEPCK by 54.8% and 18.8%,respectively,and increased the activity of GK and glycogen content in also insulin-resistant HepG2 cells by 100.6% and 98.6%,respectively. Conclusion Aqueous extracts of shirako play a role in lowering PEPCK and G-6-Pase activities and inhibiting glucogenesis, resulting in the reduction of endogenous glucose in the cell. In addition,it can augment the activity of GK,accelerate the process of glucolysis,increase the glycogen content,and alleviate insulin resistance of HepG2.

POEMS syndrome is a rare clonal plasma cell disease characterized by polyneuropathy, organomegaly, endocrinopathy, M protein, and skin changes. Significant advances have been made in the diagnosis and treatment of POEMS syndrome over the last decade. In this study, we reviewed the diagnostic criteria and characteristic features of POEMS syndrome. We also focused on the role of the characteristic features of POEMS syndrome in early diagnosis. Autologous peripheral blood stem cell transplantation has become the first-line treatment for younger patients with normal organ function because it has resulted in a high response rate and durable remission. Melphalan and dexamethasone is an effective and well-tolerated treatment for older patients and those with organ dysfunction. Patients with poor performance status or renal function can benefit from novel agents that can also improve transplantation eligibility.

Objective To investigate the causes of biliary tract complications after liver transplantation, and to put forward effective measures of prevention, diagnosis and treatment. Methods The literatures of recent years were reviewed and summarized. Results The causes of biliary tract complications after liver transplantation are very complex, and there are no standard preventive measures. Treatment differs according to causes. Conclusion One of the most important causes leading to biliary complications is preservative and ischemic injury. Poorly operative techniques and blood supply to biliary tract are also disastrous. Improving T tube placement can reduce the incidence of biliary complications related with T tube. To prevent biliary complications, it is crucial to completely wash the biliary tract, avoid damaging the blood supply to donor biliary tract and manage perfect biliary mucosa-to-mucosa anastomosis without tension. T tube cholangiography combined with noninvasive MRCP enables accurate depiction of the biliary tree and diagnosis of biliary complications. Doppler ultrosonography should be routinely applied postoperatively. Timely application of interventional radiological technique is a valuable nonoperative procedure for treatment of biliary complications. Meanwhile, biliary sludge or cholestasis and mixed infections of biliary tract should be handled actively and properly.

OBJECTIVE: To evaluate the utilization and its trend of narcotic analgetics in this hospital.METHODS: The use of narcotic analgetics during the period 2005-2007 in our hospital was analyzed retrospectively.RESULTS: The consumption quantity of narcotic analgetics in our hospital increased year-on-year,much as in the consumption of morphine preparations,with oral morphine preparations dominating the 3 first places over the 3 years,however,the increase of pethidine was slowed down in consumption quantity.CONCLUSION: The use of narcotic analgetics in our hospital is rational on the whole,but measures should be taken to tighten the control on the use of narcotic analgetics.

OBJECTIVE:To validate the microbial limit tests of Shuanghuanglian oral liquid.METHODS:The recovery rates of 4 kinds of test organisms including E.coli treated by Shuanghuanglian oral liquid were detected by routine method,culture medium dilution method,and membrane-filter procedure respectively.RESULTS:Shuanghuanglian oral liquid was found to be of bacteriostatic action.The contamination of solution couldn't be detected by routine method.The recovery rate of the test organisms detected by membrane-filter procedure was higher than by culture medium dilution method,but the recovery rates in both methods were all up to the requirement.CONCLUSION:Membrane-filter procedure should be considered preferentially in performing microbial limit test for Shuanghuanglian oral liquid.

Objective To explore the clinical application value of whole-brain CTA-CTP imaging in cerebral arteriovenous malformation (cAVM).Methods Fifteen patients diagnosed with cAVM by CTA-CTP imaging were included in this retrospective analysis study. The angioarchitecture of cAVM lesions were recorded from 4D-CTA images.Using DSA as the golden standard,the diagnostic accuracy of 4D-CTA was evaluated in 13 cases.The perfusion patterns of vessel nidus and peritumoral tissues were analyzed from the CTP images.Bleeding ratios of patients with different angioarchitecture and perfusion patterns were compared.Results 4D-CTA could dynamically display the angioarchitecture details of cAVM lesions and show the whole process of the contrast agent in and out of the vessel nidus.Although the result of 4D-CTA was consistent with that of DSA in most cases,a few fine feeding arteries and draining veins were missed.The nidus in thirteen cases was with high perfusion and the peritumoral tissues were with low perfusion.Another two cases were with low perfusion due to the presence of hematoma.Nine cAVMs suffered from small size,single feeding artery,deep venous drainage and vessel nidus with increased MTT,peritumoral tissues with decreased MTT were more likely to suffer a hemorrhage (P<0.05).Conclusion Whole-brain CTA-CTP imaging could be a valuable adjunct in noninvasive diagnosis of cAVM and predicting the bleeding risk factors.

The effects of polysaccharidical peptides (PSP) on the functions of tumour infiltrating lymphocytes (TILs) in vitro was explored. The results showed that PSP, at the concentration of 37-1200?g/ml, promoted the proliferation of TILs in dose-related manner. Combination of PSP with interleukin-2 (IL-2) enhanced the cytotoxicity of TILs and reduced the dose of IL-2 used for activating TILs. The results suggested that PSP could augment the proliferation and cytotoxicity of TILs in vitro.
