Retinoblastoma 94(RB94)gene,a new tumor suppressor gene,is found in the past several years.It has been found that Rb94 gene has a more powerful antitumor effection compared with Rb110gene.After transfection,Rb94 gene could adjust telomerase activation,induce apoptosis and regulate cell cycle.It also has a synergistic action associated with radiotherapy or chemotherapy.

0.1mv. The forty animals were randomly divided into five groups of eight animals each: in group I normal saline 5.2ml?kg-1?h-1 was infused (control); while in group II , III , IV and V propofol was infused at a rate of 30,45, 60,75mg?kg-1?h-1 for 30 min. MAP, HR, left ventricular systolic pressure (LVSP), left ventricular end-diastolic pressure (LVEDP), ? dp/dtmax and myocardial oxygen consumption index were recorded before and 30 min after drug administration. Blood samples was taken at the end of 30 min propofol infusion for determination of plasma propofol concentration. Myocardial tissue was taken for electron microscopic examination in some rats. The extent of infarct area was determined by TTC staining. Results The plasma propofol concentration ranged from 3.4?0.9 to (12.9 ? 2.4) ?g/ml. Propofol significantly decreased MAP, HR, LVSP,? dp/dtmax and myocardial oxygen consumption index in a dose-dependent manner. The size of myocardial infarct area ranged from 23.7% to 29.2% but there was significant difference in the size of infarct area and myocardial ultrastructure between the five groups. Conclusions Propofol inhibits hemodynamics in rats with acute myocardial infarction but has little effect on infarct size and ultrastruture of myocardial tissue.

Objective To observe the curative effects of metformin combined with cyproterone therapy on polycystic ovary syndrome(PCOS). Methods Ninety diagnosed PCOS patients were treated. The serum luteinizing hormone(LH), luteinizing hormone and follicule stimulating hormone(LH/FSH) ratio and T, waist hip ratio(WHR) of the patients before therapy were compared with using merformin combined with- cyproterone three cycles. Results A significant reduction(P<0.05 or P<0.01) in LH,LH/FSH,T and WHR of patients after the therapy was observed. Menses became regular after the therapy, and ache and hirsutism mitigated. Conclusion Metformin com- bined with cyproterone is a perfect means to treat polycystic ovary syndrome(PCOS).

Persistent infection with hepatitis B virus (HBV)is associated with host immune response.CD4 +T cells play an important role in HBV-specific immune response.The restoration of HBV-specific T-cell response after antiviral therapy using nucleoside and nucleo-tide analogues is also associated with CD4 +T cells.In recent years,two new subsets of CD4 +T cells,namely regulatory T cells (Tregs) and T helper 17 cells (Th17 cells),have been identified and shown to be related to disease progression and liver damage in patients with persistent HBV infection.Here we primarily summarized the differentiation and function of Tregs and Th17 cells and reviewed the interaction between the two types of cells in persistent infection and their changes after clinical antiviral therapy.We hope it will be helpful to clinical immunotherapy and prognostic assessment.

Objective:To investigate the changes of humoral and cellular immunity markers in various liver disease by ABO blood group,the reliable evidences were provided.Methods:The cases of 500 health men (NC) as contrals,various acute and chronic liver disease with the positive index of hepatitis B which include acute hepatitis (ASC) 140 cases,chronic hepatitis (CH) 192 cases,post-hepatitis cirrhosis (LC) 160 cases,primary hepatocellular carcinoma (PHC) 70 cases were examined by immune-spresding assay,APAAP immune-bridge assay and so on in the study,the changes of serumal IgG,IgM,IgA,IgD,Ige,complement C_3(C_3),total complment (CH50),circulatory,immune complex (CIC),E-rosetter formation rate (E-RFC) and T-lymphocyte subsets in the group of NC,ASC,CH,LC and PHC were investigated respectively. Results:Compared to contrals,the humoral immune markers of all groups of liver disease changed markedly,Ige increased changed apparently and IgG increased.Secondly from ASC,CH,LC, to PHC,mean while,C_3 and CIC increased obviously and E-RFC decreased obviously in the group of PHC.Compared to the group of other blood type incresed markedly (P

OBJECTIVE: To evaluate the efficacy and safety of tacrolimus (FK506) instead of cyclosporine (CsA) in renal transplant recipients with hepatic impairment. METHODS: Eighteen patients with hepatic impairment, including 10 male and 8 females, aged 19-68 years (mean aged 40 years), 2 out of them suffered diabetes mellitus, 1 of them had hepatitis B prior to operation. After operation, all patients were treated with CsA 6 mg/(kg?d), the mass concentration was changed from 250-400 ?g/L at 1 month after operation to 250 ?g/L after half year. Totally 30 mg/d prednisone was used at first and changed to 20 mg/d at 1 month after operation. Mycophenolate was applied with 1.5 g/d, or azothioprine 50-100 mg/d. FK506 was used instead of CsA when alanine aminotransferase was over 1 500 nkat/L, with over 25.1 ?mol/L bilirubin direct. The initial dose of FK506 was 0.1 mg/(kg?d) at the second day after drug withdrawal and adjusted to base on its blood trough levels and the degree of hepatic impairment. The dosage of mycophenolate or prednisone was invariably. RESULTS: Hepatic function and bilirubin metabolism of all patients were returned to normal leverl without reject reaction in 15-60 days. One patient, who had severe hepatic impairment, was recovered in 46 days. Five patients had high blood sugar levels, and one had high blood cholesterol. After hypoglycemic and cholesterol lowering therapy, the blood glucose was controlled below 7.5 mmol/L from at the beginning of (16.7?2.8) mmol/L, and the blood fat was kept in a normal level. CONCLUSION: FK506 substituting for CsA can recover hepatic function with high safety in recipients with hepatic impairment.

Purpose:To study the efficacy and toxicity of g emcitabine/cisplatin(GP) and gemcitabine/carboplatin(GC) in patients with advanc ed non-small-cell lung cancer(NSCLC). Methods:patients for GP: gemcitabine 1 000 mg/m 2,days 1 a nd 8 plus cisplatin 30 mg/m 2 days 1-3 or GC:gemcitabine 1 000 mg/m 2 , days 1 and 8 plus carboplatin AUC=5 day 1. Cycles were repeated every 3 weeks. Results:54 patients to GP and 52 to GC. The objective response rate(CR+PR)was 48.1% for GP and 44.2% for GC. No significant differences between arms were observed in response rate. No significant differences between arms we re observed in median time to progression(6.8 months GP, 6.2 months GC).GP arm h ad a remarkably higher incidence of grade nausea/vomiting Ⅲ-Ⅳ than GC arm(P

OBJECTIVETo explore the effect of electroacupuncture (EA) on the expression of Ghrelin and mRNA expression of its receptor in functional dyspepsia (FD) rats.

METHODSTotally 80 rats were divided into the normal group, the model group, the drug therapy group, and the EA group according to random digit table, 20 in each group. FD model was duplicated by clipping tail modeling. Drug containing cisapride [2 mL/100 g, 0.09 g/(kg x d)] was administered to rats in the drug therapy group from the 3rd day after successful modeling, once per day. EA at Zusanli (ST36) (0.3-0.5 cun) and Taichong (LR3) (0.1-0.2 cun) was performed in the EA group. The twirling of needle was performed to the subsidence of needle, and then the needle was connected to HANS-200A Acupoint Nerve Stimulating Device using disperse-dense wave at 2 Hz, 2 mA, 30 min each time, once per day. Six days consisted of one therapeutic course, two courses in total with an interval of one day. The intestinal propulsive rate of ink was observed. Ghrelin protein expression in gastric tissue was detected by Western blot. mRNA expression of growth hormone secretagogue receptor (GHS-R) in stomach, hypothalamus, and hippocampus was detected using Real-time PCR respectively.

RESULTSCompared with the normal group, the intestinal propulsive rate of ink, Ghrelin protein expression in gastric tissue, mRNA expression of GHS-R in stomach, hypothalamus, and hippocampus decreased in the model group (P < 0.05, P < 0.01). Compared with the model group, the intestinal propulsive rate of ink, Ghrelin protein expression in gastric tissue, mRNA expression of GHS-R in stomach, hypothalamus, and hippocampus increased in the EA group (P < 0.01); mRNA expression of GHS-R in stomach, hypothalamus, and hippocampus increased in the drug therapy group (P < 0.01). Compared with the drug therapy group, Ghrelin protein expression in gastric tissue, mRNA expression of GHS-R in hypothalamus increased in the EA group (P < 0.05, P < 0.01).

CONCLUSIONEA could regulate Ghrelin content and GHS-R mRNA expression of FD rat hypothalamus, hippocampus, and gastric tissue, and promote the intestinal propulsive rate of ink.
