ObjectiveTo investigate the clinical curative effect of traditional Chinese medicineKuiyu decoction combined with quadruple therapy for peptic ulcer (PU).MethodsThis study was a randomized controlled trial. 82 patients with PU and conformed to the indusive criteria were randomly divided into a control group and a treatment group by the random number table method, with 41 cases in each group. The control group was treated with quadruple therapy, while the treatment group was treated with traditional Chinese medicineKuiyu decoction based on the treatment of the control group. Integral change of main symptoms before and after treatment and the level changes of serum motilin (MTL), somatostatin (SS) of the two groups before and after treatment were compared and clinical total effective rate was evaluated.ResultsThe total effective rate was 95.1% (39/41) in the treatment group and 80.5% (33/41) in the control group. There was statistical difference between the two groups(χ2=4.100,P=0.043). Stomach pain (0.58 ± 0.21vs.0.73 ± 0.28,t=2.744), gasteremphraxis (0.35 ± 0.12vs.0.43 ± 0.14,t=2.778), sour regurgitation integral (0.28 ± 0.09vs.0.34 ± 0.11,t=2.703) and serum MTL level (358.5 ± 81.3 pg/mlvs.422.8 ± 86.9 pg/ml,t=3.460) in the treatment group were lower than those in the control group (P<0.01);the serum SS level (87.5 ± 18.7 pg/mlvs.73.8 ± 17.9 pg/ml,t=3.389) in the treatment group was higher than that in the control group(P<0.01).ConclusionsTraditional Chinese medicineKuiyu decoction combined with quadruple therapy for the patients with PU can promote SS secretion through decreasing MTL, so it can improve the clinical effect.

Objective To study the risk factors influencing the prognosis in the children patients with acute gastrointestinal dysfunction and to seek their therapeutic measures. Methods The clinical data of 125 cases patients with acute gastrointestinal dysfunction were retrospectively analyzed. The risk factors possibly influencing the prognosis were analyzed by multivariate statistical Logistic analysis. Results Among 125 children patients, 61 cases died, and the mortality rate was 48.8%. Logistic regression analysis indicated that poor circulation, cardiovascular system failure, hepatic failure, brain failure were significant risk factors of death associated with acute gastrointestinal dysfunction. (OR = 4.156, 3.330, 6.903, P<0.05 or<0.01). Conclusions Poor circulation, cardiovascular system failure, hepatic failure and brain failure are significant risk factors of death associated with acute gastrointestinal dysfunction.

Objective To investigate the auxiliary effects of huaier granule on hepatoeellular carcinoma (HCC)patients after liver transplantation.Methods Sixty HCC patients who had undergone liver transplantation from Julv 2004 to June 2006 and met the standard of UCSF were involved in this study.All patients were divided into huaier granule group(n=20),chemotherapy group(n=15),huaier granule+chemotherapy group (n=15)and control group(n=10).The white blood cell count,liver function,cell immunity and immunologieal reiection were detected.The 1-year tumor recurrence rate wag calculated.Results The white blood cell counts in chemotherapy group 1,3,and 6 months after treatment were significantly lower than that before treatment (F=62.053,58.472,49.807,P＜0.05).The changes of white blood cell counts of the other 3 groups before and aftertreatment were small.The difference on the white blood cell counts of the 4 groups had no statistical 8ignincanee(F=102.361,113.412,87.572,P＜0.05).The NK activity,CD4+/CD8+ ratio,IL-2 level in huaier granule group and huaier granule+chemotherapy group 1,3,6 months after treatment were significantly higher than those before treatment,and were significantly higher than those in chemotherapy group and control group(P＜0.05).No immunological rejection occurred in all the groups.Two patients in each group had recurrence and metastasis of HCC within 1 year after the treatment.and the incidence in control group was higher than the other 3 groups(P＜0.05). Conclusions Humer granule can increase the white blood cell count which is decreased after chemotherapy,impmve cellular immunity,and effectively suppress the recurrence and metastasis of HCC at the first year after operation.

Aim To investigate the inhibitory effects and mechanism of action of isoliensinine (IL) on the proliferation of porcine coronary arterial smooth muscle cells (CASMCs) induced by phenylephrine (Phen) and its mechanisms of action. Methods MTT assay, immunohistochemical method and Western blotting were adopted. Results IL (0.03-3 μmol·L-1) could inhibit the CASMCs proliferation induced by Phen (0.1 μmol·L-1) in a concentration-dependent manner. IL (0.1 μmol·L-1) antagonized Phen-induced overexpression of PDGF-β and bFGF from 0.545±0.026 and 0.47±0.03 to 0.458±0.019 and 0.376±0.017 (P<0.01, P<0.01). IL (0.1 μmol·L-1) also decreased c-fos, c-myc and hsp70 overexpression induced by Phen from 0.57±0.04, 0.44±0.04 and (173±36)% to 0.46±0.05, 0.372±0.021 and (115±35)% respectively (P<0.01, P<0.01, P<0.01). Conclusion IL exerted antiproliferative effect on CASMCs induced by phenylephrine, and its mechanisms were related to decrease the overexpression of growth factors (PDGF-β, bFGF), protooncogene (c-fos, c-myc) and hsp70.

Objective To inactivate Death-associated protein kinase 1 gene (DAPK1) by transfecting complementary methylated oligonucleotides and studies its effect on the proliferation of myelogenous leukemia cell line K562. Methods Methylated oligonucleotides complementary to DAPK1 gene promoter were transfected into K562 cells by Iipo2000. Methylation specific PCR (MSP) and Reverse transcription PCR (RT-PCR) were applied to detect DAPK1 gene promoter methylation status and its mRNA expressions respectively. MTT was used to detect the proliferation of K562 cells pre- and post- oligonucleotides transfection. Results DAPK1 gene promoter in non-treated and control groups were unmethylated with detectable mRNA expressions, but it became methylated with inhibited mRNA expressions after methylated oligonucleotide transfection. Proliferation in methylated oligonucleotide treatment group was significantly higher than that in non-treated and control groups. Conclusion Complementary methylated oligonucleotides could inactivate DAPK1 gene and inhibit its expression in K562 cells, which could promote its proliferation.

Objective To observe the characteristic features of musculoskeletal ultrasound (MSUS) in gouty arthritis (GA) and to assess its value in GA diagnosis.Methods Patients with GA and non-GA who underwent MSUS examination in Chinese PLA General Hospital were enrolled in this study. The synovitis,tenosynovitis,soft tissue swelling,bone erosion,bursitis and ossification were measured by greyscale ultrasound,and the synovial vascularity was measured by power Doppler ultrasound to evaluate the degree of inflammation.Results The ultrasound images of GA were intended to have specific features like tophus,hyperechoic deposition on the surface of the articular hyaline cartilage ( double contour sign ),hyperechoic deposition in the synovium appearing as bright stippled foci,and bright strap in tendons with a significant difference when compared with non-GA group (P ＜ 0.05).The percentage of tenosynovitis and bone erosion in non-GA group was higher than that in the GA group with a significant difference (P ＜0.05 ). Tophus,double contour sign,bright stippled foci or bright stippled foci in tendons together suggested gout with a specificity of 92.4％ and a sensitivity of 60.3％,the AUC of ROC was 0.764 ( P ＜0.05).Conclusion Tophus,double contour sign,bright foci and bright strap detected by MSUS are of diagnostic value on GA and MSUS may be a promising tool in diagnosing GA.

Objective: To analyze the phytosterols content in cereals and legumes commonly consumed in China, and to estimate the intake of phytosterols in Chinese people. Methods: 25 cereals and 16 legumes were chosen as samples. The content of ?-sitosterol, campesterol, stigmasterol, ?-sitostanol, campestanol were analyzed by GC methods and the total phytosterols were calculated; The intake of phytosterols in Chinese people were estimated using the data of “Survey on the Status of Nutrition and Health of the Chinese People” in 2002. Results: The content of phytosterols in wheat flour was higher than that in rice. The refinements of cereals will decrease the phytosterols content. Phytosterols content in soybean was higher than other legumes. The intake of phytosterols in Chinese people was estimated to be 130.76mg/d from cereals and 7.86mg/d from legumes. Conclusion: The analysis of phytosterols in food and the estimation of daily intake is valuable for chronic disease prevention. The higher consumption of wheat flour and legumes in diet is recommended.
