Objective:To study the curative effect of hydrotalcite combined with omeprazole in the treatment of gastric ulcer with gastric bleeding. Methods:Seventy-six patients with gastric ulcer and bleeding in the stomach were selected and randomly divided into two groups. Thirty-two patients in the control group were treated with omeprazole alone while 44 patients in the observation group were treated with hydrotalcite combined with omeprazole. The therapeutic effects were compared between the two groups. Results:The total effective rate in the observation group was 100% while that was 87. 5% in the control group,and the difference between the two groups was statistically significant(P<0. 05). The comprehensive score of symptoms of the patients in the observation group was(4. 2 ± 1. 2)while that was(6. 2 ± 1. 4)in the control group,and the difference was significant(P<0. 01). The abdominal pain,abdominal distention and belching remission time in the observation group were slightly shorter than those in the control group(P<0. 05)and the time of hematemesis and hemafecia remission was significantly shorter than that in the control group(P<0. 05). After the 3-month treatment,the re-bleeding rate in the observation group was 6. 82%,which was slightly better than that in the control group,and the difference had no statistical significance(P<0. 05). The incidence of adverse reactions in the observation group was 9. 09% while that was 6. 25% in the control group,and there was no significant difference between the two groups(P>0. 05). Conclusion:Hydro-talcite combined with omeprazole in the treatment of gastric ulcer with gastric bleeding is effective and safe.

Objective To investigate correlation between the expression of TIG1 and the prognostic significance in acute leukemia (AL).Methods The TIG1 expression level of 75 AL and 20 normal control (NC) were measured by Real-Time Quantitative PCR(RT-QT-PCR).Results TIG1 gene expressed at a higher level in NC(0.0609±0.0281 ) than that in de novo AL(0.0057±0.0035)(U=-6.321,P=0.000).The expression of TIG1 in complete remission patients(AL-CR)(0.0409±0.0244)were lower than that in NC too(U=-2.582,P=0.01).The expression of TIG1 in AL-CR patients (83.3 ％) were higher than that in de novo AL (53.1％)(U=-6.366,P=0.000).In AL patients,the CR rate of high TIG1 level cases were higher than that in low level cases (x2=4.563,P=0.033).Conclusions Reduced expression of TIG1 may play an important role in the pathogenesis of AL.TIG1 can serve as a marker of poor prognosis in AL.

To explore the risk factors of acute kidney injury(AKI)in adult primary nephrotic syndrome(PNS). Totally 185 patients with PNS were divided into AKI group(=51)and non-AKI group(=134).The demographic data and clinical and histological features at admission were compared between the two groups.The independent risk factors for AKI were evaluated by Logistics regression analysis. In 51 PNS patients with AKI,the common pathological types of AKI included minor glomerular abnormalities(29.4%),IgA nephropathy(25.5%),and membranous nephropathy(17.6%).The incidences of renal tubular casts and epithelial vacuoles in the AKI group were significantly higher than those in the non-AKI group(=0.004,=0.030).Males were more likely to suffer from AKI than females(=0.000).Patients in AKI group had significantly lower albumin level(=0.015)and higher levels of random urine protein,serum creatinine,uric acid,urea nitrogen,and triglyceride than non-AKI group(=0.030,=0.000,=0.000,=0.000,and =0.006),and polyserous and oliguria occurred more often in the AKI group(=0.000,=0.002).The AKI group had significantly higher incidences of high blood pressure and infections(=0.035,=0.000).Multivariate logistics regression analysis showed albumin(<25 g/L),serum creatinine(>96 μmol/L),urea nitrogen(≥6.8 mmol/L),uric acid(≥400 μmol/L),diabetes,infection,and renal tubular casts were the independent risk factors for AKI. AKI complicating PNS is associated with a variety of factors.Its independent risk factors include the levles of albumin,serum creatinine,urea nitrogen,and uric acid,diabetes,infections,and renal tubular casts.

Objective To investigate the relationship between interaction of peroxisome proliferators-activated receptor alpha (PPARα), cytochrome P450 oxysterol 7α-hydroxylase (CYP7B1) and estrogen receptor (ER) and intrahepatic cholestasis in pregnant rats. Methods Eighty clean SD pregnant rats were selected and divided into four groups randomly with 20 in each. Since the 13th day of pregnancy,rats in the control group was injected subcutaneously with refined vegetable oil 2.0 ml · kg-1 · d -1 , those in the low-dose, moderate-dose and high-dose groups received 17-α-ethynylestradiol (EE) 1.0 mg · kg-1 · d-1,1.25 mg · kg-1 · d-1 and 1.5 mg · kg-1 · d-1, respectively. All rats were sacrificed at the 21at day of pregnancy and maternal hepatic tissues were collected. The serum levels of alanine aminotransferase(ALT), aspartate transaminase (AST), total bile acid (TBA) and bilirubin (BIL) were determined by enzyme linked immunosorbent assay (ELISA). The mRNA expressions of PPARα, CYP7B1, Erα and Erβ in maternal rat livers were examined by real-time PCR. Results (1) Biochemical indicators: the serum levels of ALT,AST, TBA and BIL were significantly lower in the control group than in the rest 3 groups,respectively [ control group: (41.1 ± 2.8 ) U/L, (44.4 ± 3.6) U/L, (26.4 ± 5.6 ) μmol/L and( 2.8 ± 0.2)U/L;low-dose group: (48.2 ±3.4) U/L,(47.9 ±3.7) U/L,(36.4 ±4.2) μmol/L and (4.2 ±0.2) U/L;moderate-dose group: (70.4 ± 5.3 ) U/L, (68.4 ± 5.6) U/L, (64.3 ± 3.8 ) μmol/L and ( 6.2 ± 1.2)U/L; high-dose group: (72.4 ±7.6) U/L, (70.2 ±3.8) U/L, (72.4 ±7.8) μmol/L and (8.2 ±2.2)U/L, P<0.05], and those in the moderate or high-dose groups were higher than in the low-dose group (P<0.05). (2) mRNA expression of Erα and Erβ: the mRNA expression of Erα in pregnant rat livers increased in a dose-dependent manner, which were all significantly higher than that in the control group,respectively ( low-dose group: 0.76 ± 0.02 ); moderate -dose group: ( 0.99 ± 0.04; high-dose group:1.21 ±0.01 ;control group:0.65 ±0.01, P <0.05), but no difference was found among the 4 groups in the mRNA expression of Erβ ( P > 0.05 ). (3) mRNA expression of CYP7B1 and PPARα: the mRNA expression of CYP7B1 in pregnant rat livers increased from the low-dose group to the high-dose group, and were all higher than that of the control group ( low-dose group: 0.93 ± 0.01; moderate-dose group: 0.99 ±0.06; high-dose group: 1.22 ± 0.04; control group: 0.75 ± 0.02, P < 0.05 ). However, the mRNA expression of PPARα decreased from the low-dose group to the high-dose group, and were all lower than that of the control group (low-dose group: 0.83 ± 0.05; moderate-dose group: 0.71 ± 0.02; high-dose group:0.64 ± 0.03; control group: 1.35 ± 0. 05; P < 0.05 ) . Conclusions The down regulated mRNA expression of PPARα, caused by higher dose of estrogen, may increase the expression of CYP7B1 due to the ineffectiveness of the inhibition of PPARα on CYP7B1, which may further stimulate the Erα activity and then induce intrahepatic cholestasis. Abnormal expression of PPARα, CYP7B1 and ER may play a role in the pathogenesis of estrogen-induced intrahepatic cholestasis.

B cell maturation antigen (BCMA) is a receptor of B lymphocyte stimulator (BLyS). Human IgG1Fc fusion proteins with the extracellular domain of BCMA(eBCMA), also called decoy receptors, have beenused as a potential BLyS antagonists to block BLyS activities. In order to design novel BLyS antagonistpeptides, computer-aided homologue modeling was used to construct an eBCMA-Fc fusion protein based on thecrystal structures of BCMA and Fc fragmant. To ensure the activity of eBCMA not to be interfered by Fcfusion, the root mean square distance (RMSD) for eBCMA and Fc were calculated to be 0.036 nm and 0.064nm, respectively, based on molecular docking modeling. An eBCMA-Fc fusion gene was constructed andintroduced into E. coli for expression. As expected, the purified 36 kD eBCMA-Fc fusion protein was able tobind BLyS in vitro at a dosage-dependent manner and demonstrated an anti-proliferative activity induced byBLyS in Daudi cells. The results have provided useful information on the evaluation of computer modeling andthe in vitro biological activity for the design of potential BLyS antagonist peptides.
