Objective:To study the HBV infection in peripheral blood mononuclear cells in mediating the role of mother -to-child transmission of hepatitis B virus.Methods: The peripheral blood mononuclear cells ( PBMCs ) in maternal and cord blood mononuclear cells ( CBMCs ) in newborns were conventionally isolated by Ficoll-Hypaque medium.The loads of HBV-DNA in peripheral blood of maternal and cord blood of newborns were both detected by PCR .Results:The clinical data showed that the positive detection rates of HBV-DNA in serum and PBMCs of pregnant women with HBeAg (+) were 100.00%( 25/25 ) and 72.00%( 18/25),and the positive detection rates of HBV-DNA in the neonatal umbilical cord blood serum and CBMCs were 60.00%(15/25) and 44.00%(11/25),respectively.There were significantly difference between HBeAg (+) and HBeAg(-) in the pregnant women (P<0.05 ).The positive detection rates of HBV-DNA in neonatal umbilical cord blood serum and CBMCs were higher in the group with high HBV loads (more than 106copies/ml) in PBMCs than those of low HBV loading group (102-103copies/ml).The significantly difference was explored between the two groups.Conclusion: Mononuclear cells can not only be infected by HBV , but also play a critical role in the intrauterine vertical transmission of HBV via the pathway transmitted from PBMCs in pregnant women to CBMCs in newborns.

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 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.

Objective To compare the model for end-stage liver disease (MELD) and PT in survival prediction of hepatitis B patients with acute-on-chronic liver failure. Methods One hundred and thirty-nine hepatitis B patients with acute-on-chronic liver failure were divided into survival and death group, and evaluated by MELD and FT. The area under ROC curve was used to compare the MELD and PT. The mortality was observed within 3 months. Results The MELD score and PT of survival group was 25.09 ± 3.92 and (26.46 ± 6.46) seconds respectively, and those for the death group were 36.25 ± 6.42 and (40.78 ± 10.80) seconds. The differences were of statistical significance ( P < 0.01 ). MELD score showed significant correlations with PT(r =0.824, P <0.01). The area under ROC curve was 0.936 (95% CI 0.895 ± 0.977 ) on MELD score and 0. 890 (95 % CI 0.839 ± 0.941 ) on PT, and there was no significant difference between them. Conclusions Both MELD score and PT can accurately predict the short-term prognosis of hepatitis B patients with acute-on-chronic liver failure. The validity of prognosis by MELD is similar to PT. The mortality increases with the MELD score and PT increasing.

Recently,basic and clinical researches have shown that blood glucose variability is an independent risk factor for diabetic complications.Thus,ideal control of blood glucose is not only to reach the HbA1Ctarget,but also to minimize blood glucose variability.Different glycemic parameters could be selectedaccording to different purpose of evaluation,in which the mean amplitude of glucose excursions(MAGE) and the standard deviation of blood glucose (SDBG) could be used as accurate and simple assessment parameters respectively.

LDM, a product of the combination of contemporary information network technology and the tradi tional medical mode, is a rapidly developing new undertaking of recent years. The transformation of the medical mode in the establishment of LDM has brought about a series of problerms, including quality control of LDM, delegation of responsibility in IDM, standardization and unification of LDM, and psychological problems of patients under the mode of LDM. These problems present issues of new contemplation and exploration for hospital managers.

Objective To investigate the effect of seasonal variation of blood pressure (BP) on the incidence of cardiovascular and cerebrovascular events in the elderly aged 80 years and over.Methods The 67 patients (aged 80-86 years) with essential hypertension were enrolled, the BP were measured at home, in consulting room, and by 24-h ambulatory BP monitor in every season for 2 years. The incidences of cardiovascular and cerebrovascular events were recorded in the meantime.Results Both systolic BP (SBP) and diastolic BP (DBP) were lower in summer than in any other season (P＜0. 01 ). SBP was higher in winter than in any other season. (P＜0.01), DBP was higher in winter than in summer(P＜0. 01). There were no significant differences in SBP and DBP between spring and autumn. The incidence of cardiovascular and cerebrovascular events were higher in winter and summer than in spring and autumn (P＜0.05). The season (OR= 1. 525, P=0. 001), BMI (OR =1.145, P=0.018) and heart function (OR= 2. 037, P=0.01) were related to the incidence of cardiovascular events. And the season (OR = 1. 604, P= 0. 001 ), history of cerebrovascular disease (OR= 1. 598, P=0. 034), office-measured SBP (OR=0.960, P=0.013) and ambulatory DBP (OR =0. 936, P = 0. 008) were related to the incidence of cerebrovascular events.Conclusions The blood pressure measured by three methods in the elderly aged 80 and over shows that both SBP and DBP are at the lowest in summer; SBP is at the highest in winter, DBP is higher in winter than in summer. There are no significant differences in BP between spring and autumn. The incidences of cardiovascular and cerebrovascular events are significantly higher in winter and summer than in spring and autumn.

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.
