Objective To investigate clinical and pathological features of chronic hepatitis B ( CHB) with nonalcoholic fatty liver disease(NAFLD).Methods The clinical and pathological data of 70cases of CHB and 68 cases of CHB with NAFLD and 42cases of NAFLD were analyzed and compared .Results In this patients with CHB overlapped NAFLD , plasma ALT,AST,GGT con-centrations were higher than that in CHB and NAFLD groups ( P <0.05 , P <0.01 ) , compared with CHB group ,the levels of serum TC,TG,FBS,INS and IRI on patients with CHB overlapped NAFLD were increased ( P <0.05, P <0.01), Compared to patients B groups, serum hepatitis B virus DNA titer in patients with steatosis was significantly lower ( P <0.05) and reduced sharply with the increasea degree of hepatic steatosis ( P <0.05 ) .hepatic inflammation grade and fibrosis stage between CHB patients with and with-out steatosis ( P >0.05 ) .Conclusions The reverse association of hepatitis B virus titer with the degree of hepatic steatosis needs further investigation .Hepatic steatosis is associated with metabolic factors than virus factors .The existence of hepatic fatty degeneration dose not exacerbate liver inflammation or fibrosis .

Objective To investigate the mutations of basal core promoter (BCP) and precore (PreC) region of hepatitis B virus (HBV) and the association with the development of hepatocellular carcinoma in patients with chronic HBV infection.Methods Totally 381 untreated HBV patients were recruited from the Department of Infectious Diseases,People's Hospital of Shangyu from Jan 2003 to Dec 2010,which included patients with chronic hepatitis B (CHB,n =166),cirrhotic hepatocellular carcinoma (cirrhotic-HCC,n =158) and noncirrhotic hepatocellular carcinoma (noncirrhotic-HCC,n=57).The mutations in HBV BCP and PreC and the genotypes of HBV were determined by polymerase chain reaction (PCR) and direct sequencing.Data were analyzed by chi square test and Logistic regression.Results The HBV genotype of most cases was genotype B (CHB,n =124;cirrhotic-HCC,n=126 ; noncirrhotic-HCC,n=50).In univariant analysis,BCP V1753 (x2 =7.927,P=0.005),BCP T1762/A1764 (x2 =12.796,P＜0.01),PreC A1896 (x2 =6.890,P=0.009) and PreC A1899 (x2=11.850,P =0.001) mutations were more frequently detected in cirrhotic-HCC patients than those in CHB patients.PreC A1896 (x2 =27.310,P＜0.01) and A1899 (x2=7.575,P=0.006) mutations were highly detected in noncirrhotic-HCC patients than those in CHB patients.Multivariate Logistic regression analysis revealed that in HBeAg positive patients,BCP T1762/A1764 (wald=6.180,P=0.016,OR=8.883) and PreC A1899 (wald=10.279,P=0.001,OR=7.475) mutations were independently associated with the development of cirrhotic-HCC; PreC A1896 (wald=4.324,P=0.038,OR=4.439) and PreC A1899 (wald=4.850,P=0.028,OR=6.010)mutations were independently associated with the development of noncirrhotic-HCC.While in HBeAg negative patients,PreC A1896 mutation (wald=15.448,P＜0.01,OR=12.128) was independently associated with the development of noncirrhotic-HCC.Conclusions BCP T1762/A1764 mutations are associated with the development of cirrhotic-HCC in HBeAg positive patients.PreC A1896 mutation is associated with the development of noncirrhotic-HCC in HBeAg positive and HBeAg negative patients.PreC A1899 mutation is associated with the development of cirrhotic-HCC and noncirrhotic-HCC in HBeAg positive patients.

Objective To compare the pre-existing mutations in reverse transcription region of HBV in patients with different HBV infection stages.Methods Totally 474 patients with chronic HBV infections,including 205 with chronic hepatitis B (CHB),153 with liver cirrhosis and 116 with hepatocellular carcinoma (HCC),were enrolled from the People' s Hospital of Shangyu and the First Affiliated Hospital of Zhejiang University during January 2011 and June 2013.All patients had not received nucleos (t)ide analogues treatment.HBV RT region mutations and genotypes were determined by PCR followed by sequencing.SPSS14.0 was used for statistical analysis.Results There were 387 (81.6％) patients with HBV genotype B,in which 156 were with CHB,124 were with liver cirrhosis,and 107 were with HCC.Nucleos(t)ide analogues-related mutations were observed in all the above 387 patients.rtS106C mutation was more popular in CHB and liver cirrhosis (14.1％ and 14.5％) patients than that in patients with HCC (4.7％) (x2 =6.126,6.207,P ＜0.05); And the positive rates of rtD134E/G/N/S mutations were also higher in CHB and cirrhotic patients (21.8％ and 20.2％) than that in HCC patients (10.3％,x2 =5.933,4.263,P ＜ 0.05).rtD134E/G/N/S and rtS106C mutations were correlated with HBeAg (P ＜0.01) and gender (P ＜ 0.05),but not with HBV virus load and age (P ＞ 0.05).The mutation frequencies in A-B interdomain were higher in CHB and cirrhotic patients (5.3％ and 5.6％) than that in HCC patients (3.5％,x2 =9.018,11.018,P ＜ 0.01).Conclusions Nucleos (t) ide analogues-related mutations exist in various HBV infection stages.rtSl06C and rtD134E/G/N/S mutations may be involved in necro-inflammation,and A-B interdomain mutations may be correlated with necro-inflammation,immune response and fibrosis in chronic liver diseases.

Objective To investigate the effect of paliperidone extended-release combined with modified electric convulsive therapy(MECT) on cognitive function in patients with refractory schizophrenia. Methods 30 patients were reviewed with the Wisconsin Card SortingTest (WCST), the Trail Making Test A and B, Digit Span Test (DST), Digit Symbol Substitution Test (DSST) and the Clinical MemoryScale (CMS). Results The time shortened after treatment in the Trail Making Test A and B (P<0.05). There was no significant difference beforeand after the treatment in the other tests. Conclusion Paliperidone combined with modified electric convulsive therapy may inmprovethe memory and attention in schizophrenics.

AIM: To evaluate the effect of carbon monoxide(CO) on the permeability of brain blood barrier(BBB) in cerebral ischemic rats. METHODS: SD rats were divided into three groups. Saline, hemin or ZnPP were injected intraperitoneally 12 h before middle cerebral artery occlusion (MCAO), respectively. The concentration of blood CO and the permeability of BBB at 24 h after MCAO were measured. RESULTS: The CO concentration in blood in hemin group was higher than that in saline group( P 0.05). CONCLUSION: CO reduced the permeability of BBB as a messenger gas molecular when its intrinsic concentration was elevated.

Objective To compare the 2-year efficacy of de novo combination therapy with lamivudine (LAM) and adefovir dipivoxil (ADV) to that of entecavir (ETV) monotherapy in treatment of patients with hepatitis B virus ( HBV )-related decompensated cirrhosis.Methods A total of 120 naive patients with HBV-related decompensated cirrhosis admitted to Shangyu People's Hospital and the First Affiliated Hospital of Zhejiang University from January 2007 to April 2008 were enrolled,in which 60 were treated with LAM and ADV combination therapy,and other 60 patients were treated with ETV monotherapy.Tests for liver and kidney function,alpha-fetoprotein,HBV serum markers,HBV DNA load,prothrombin time (PT),and ultrasonography or CT scan of liver were performed every 1-3 months.Repeated measure ANOVA and x2test were used to compare the efficacy,side effects and accumulated survival rates at 12 and 24 month in two groups.Results Forty-five patients in each group were followed-up for 24 months.There was no significant difference in HBV DNA negative rates and ALT normalization rates at month 12 (x2 =2.12 and 2.88,P ＞0.05 ) and month 24 between two groups (x2 =3.21 and 3.24,P ＞ 0.05); while HBeAg seroconversion rate in LAM + ADV group at month 24 was significantly higher than that in ETV group (43.5％ vs.36.4％,x2 =4.09,P＜0.05).Viral breakthrough occurred in 2 cases (4.4％) by month 12 and 3 cases (6.7％) by month 24 in LAM + ADV group,and no viral mutation was observed; while in ETV group,viral breakthrough occurred in 1 case ( 2.2％ ) by month 12 and 2 cases (4.4％) by month 24,and viral mutation was observed in 1 case (2.2％) by month 24.At the end of month 24,increase of AIb (F=18.9 and 17.3,P＜0.05),decrease of TBil and ALT (F=16.5,17.1 and 23.7,24.8,P ＜0.05 ),shortening of PT ( F =22.7 and 24.5,P ＜ 0.05 ),and the improvements of CTP and MELD scores (F=18.5,17.8 and 24.2,23.8,P＜0.05) were observed in both groups.The accumulative rates of mortality or liver transplantation were 16.7％ ( 10/60 ) and 18.3％ ( 11/60 ) in LAM + ADV and ETV groups,respectively.No blood creatinine increased above the normal upper limit was observed in both groups.Conclusion Both LAM + ADV combination therapy and ETV monotherapy can effectively inhibit HBV replication,improve liver function,decrease mortality and viral resistance,but the 24-month HBeAg seroconversion rate in combination therapy group is higher than that in monotherapy group.

Objective:To investigate the role of macrophage migration inhibitory factor (MIF) in severe acute pancreatitis (SAP) associated lung injury in mice.Methods:Totally 32 mice were randomly divided into 4 groups ( n=8/per group): wild type control group (WT+CON group), wild type SAP group (WT+SAP group), MIF gene knockout control group (KO+CON group), and MIF gene knockout SAP group (KO+SAP group). SAP model was established by intraperitoneal injection of L-arginine (4 mg/g). The expression of serum amylase, IL-6, TNF-α and MIF were detected by ELISA. The pathological changes of pancreatic and lung tissues were observed by HE staining. The expression of IL-6 and TNF-α in lung tissue was detected by immunohistochemistry. The expression of NF-κB in lung tissue was detected by Western blot. For measurement data, t test was used for comparison between two groups, and one-way analysis of variance was used for comparison between multiple groups. Results:Compared with the WT+CON group, pathological score of pancreatic and lung injury, serum amylase, TNF-α and IL-6 expression in serum and lung tissues were significantly increased in the WT+SAP group ( P<0.05), while the above indexes were significantly decreased in the KO+SAP group ( P<0.05). In addition, the expression of NF-κB protein in KO+SAP group was significantly lower than that in the WT+SAP group ( P<0.05). Conclusions:MIF gene knockout can alleviate severe acute pancreatitis associated acute lung injury in mice, and its mechanism may be related to NF-κB.

Objective To evaluate the association between LDL-C and ischemic stroke in patients with nonvalvular atrial fibrillation (AF).Method A total of 2 470 patients with nonvalvular AF were included in the present study.The clinical data and laboratory examination results of the patients in the hospital were collected.The subjects were either divided into the ischemic stroke history (n =560),and non-ischemic stroke history groups (n =1 910),or divided into the low-middle risk (n =566) and high risk groups (n =1 904) based on CHA2 DS2-VASc score.Results There were significant differences in the proportion of Han,the ratio of gender,age,hemoglobin,hematocrit,ALT,serum uric acid,HDL-C and LDL-C between the patients with ischemic stroke history and without (all P ＜ 0.05).Similarly,there were significant differences in the proportion of Han,the ratio of gender,age,white blood cell count,hemoglobin,hematocrit,platelet count,ALT,albumin,TG and LDL-C between subjects in the low-middle risk group and those in the high risk group (all P ＜ 0.05).A logistical regression analysis showed that LDL-C was an independent risk factor for both the ischemic stroke history (OR 2.089,95％ CI 1.860-2.347,P ＜0.05),and future ischemic stroke risk (OR 1.270,95％ CI 1.079-1.494,P ＜ 0.05) in patients with nonvalvular AF.Conclusion LDL-C is associated with ischemic stroke in patients with nonvalvular AF,and it is also an independent risk factor for future ischemic stroke in these patients.

Objective To study the influence of prebiotics and probiotics combined with early enteral nutrition (EN) on the recovery of gastrointestinal function, improvement of nutritional status and prognosis in postoperative patients with pancreatic trauma. Methods A retrospective analysis of the clinical data of pancreatic injury patients admitted to our hospital from January 2012 to December 2017 was carried out, and those patients were divided into 3 groups: group A (control group), patients treated with operation and routine treatment; group B, patients treated with prebiotics and probiotics in addition to surgery and routine treatment; group C, patients treated as group B in addition to early EN. Comparisons of blood biochemical markers, mortality, time required for resolution of abdominal pain, length of hospital stay, hospitalization expenses and complication rate among three groups. Results The time required for resolution of abdominal pain, length of hospital stay, hospital costs in group C were significantly lower than those in other groups (P＜ 0.05). The score of gastrointestinal dysfunction at one week after surgery in group C was significantly lower than that in group A and group B (P＜0.05). Serum amylase, lipase and CRP levels were significantly lower in group C than those in other groups (P＜ 0.05). Plasma albumin level significantly higher in group C than that in other groups (P＜ 0.05). Conclusion Prebiotics and probiotics combined with early EN treatment have certain advantages in patients with pancreatic injury.

We reported a case of neonatal Langerhans cell histiocytosis (LCH) with his clinical manifestations, examinations, diagnosis and treatment. This infant was hospitalized due to the rash and poor response. He was diagnosed as LCH after admission by imaging, skin biopsy and immunohistochemistry. The infant died because his parents refused all possible treatments. At the moment, no effective treatment is available for LCH patients, while the main managements are infection control and necessary supportive care. Pulmonary infections often contribute to the death of LCH patient and can aggravate the situation by stimulating histiocytic hyperplasia.
