Objective To analysis the effects of ulinastatin injection on neural function and the expression of S-100β protein apply to ischemic stroke patients who underwent interventional therapy.Methods A total of 92 patients with ischemic stroke were randomly divided into control group (n =46) and treatment group (n =46).The control group received conventional treatment (oral administration of atorvastatin statin 20 mg,aspirin100 mg and clopidogrel 75 mg,qd) consecutively for 30 d.On the basis of the control group,the treatment group received intravous ulinastatin 1 × 105 U (diluted in 0.9％ NaCl 250 mL) bid for 7 d (the last 7 days of the treatment).The clinical efficacy,S-100β protein,National institutes of health stroke scale (NIHSS) before and after treatment and the adverse drug reactions were compared between the two groups.Results After treatment,the total effective rates of the treatment group and control group were 95.65％ (44 cases/46 cases) and 78.26％ (36 cases/46 cases),with statistically significant difference (P ＜ 0.05).After treatment,the S-100 β protein of the treatment group and the control group respectively were (1.91 ±0.24) and (2.31 ±0.29) μg · L-1,NIHSS respectively were 9.24 ± 1.11 and 11.23 ± 1.42,and the difference was statistically significant (P ＜ 0.05).The adverse drug reaction in the treatment group was restenosis (1 case),while that of the control group were restenosis (2 cases) and cerebral ischemia (4 cases).The incidences of adverse drug reactions of the treatment group and the control group were 2.17％ (1 case/46 cases) and 13.04％ (6 cases/46 cases),with statistically significant difference (P ＜ 0.05).Conclusion Ulinastatin exerted protective effect on neural system of ischemic stroke patients who underwent interventional therapy can protect nerve function by suppressing the expression of S-100β protein.

OBJECTIVETo investigate the female sexual dysfunction (FSD) in type 2 diabetes patients, by comparing the sexual function between type 2 diabetic women and non-diabetic women with Female Sexual Function Index (FSFI).

METHODS115 type 2 diabetic women and 107 age-matched non-diabetes women were enrolled with similar backgrounds. Their sexual functions were evaluated with FSFI. Metabolic parameters such as body mass index, blood lipid profile, hemoglobin A1C, plasma glucose were also collected.

RESULTSTotal score of FSFI of the type 2 diabetic women were significantly lower than that of the non-diabetic controls (18.27±8.96 vs. 23.02±5.78, P=0.000). Scores of the FSFI domains (desire, arousal, lubrication, orgasm, satisfaction, pain) of the type 2 diabetic group were also lower than those of the control group. According to the FSD criterion (FSFI<25) available in China, the percentage of FSD in the type 2 diabetic group was significantly higher than that of the control group (79.2%vs. 55.0%, P<0.001). These trends seemed more prominent in pre-menopause subgroups. The logistic regression analysis indicated that age and diabetes were independent risk factors of FSD. Body Mass Index (BMI) also had influence in the diabetes group.

CONCLUSIONFindings from this study showed that there are more FDS in Chinese type 2 diabetic women than in their non-diabetic counterparts, especially in pre-menopause participants.

OBJECTIVETo investigate the influence of pyrrolidine dithiocarbamate (PDTC) on the expression of transforming growth factor beta(1) (TGF-beta(1)), matrix metalloproteinase-2 (MMP-2) and tissue inhibitor-1 of metalloproteinase (TIMP-1) in rats with pulmonary damage induced by paraquat (PQ).

METHODSFifty-four healthy male SD rats were randomly assigned into the control group (normal saline), the PQ-treatment groups (4 groups) and the PDTC treatment groups (4 groups). Except the rats in the control group, the rats in the PQ group were gavaged only with 40 mg/kg PQ, and PDTC group with 40 mg/kg PQ plus immediate injection 120 mg/kg PDTC (i.p). On the 3rd, the 7th, the 14th and 28th day after treatments, one group rats of each treatments were sacrificed and lung and blood samples were collected. The level of TGF-beta(1) protein in the plasma, the mRNA expression of TGF-beta(1), MMP-2 and TIMP-1 were evaluated using RT-PCR and real-time quantitative PCR, while pathological changes of lung were examined under optical microscope and electrical microscope.

RESULTSThe TGF-beta(1) protein, TGF-beta(1) and MMP-2 mRNA expression were increased significantly in the earlier stage and then decreased after PQ administration (P < 0.05 or P < 0.01), while the mRNA level of TIMP-1 was augmented continuously (P < 0.01) throughout the study compared to the control group. In comparison with the PQ group, in the PDTC treatment group, the TGF-beta(1) mRNA expression on the 3rd and the 14th day, 0.54 +/- 0.08 and 0.72 +/- 0.04 respectively, the MMP-2 mRNA expression on the 7th and 14th day, 1.62 +/- 0.50 and 1.97 +/- 0.34 respective-ly, and the TIMP-1 mRNA on the 7th and 21st day, 1.79 +/- 0.21 and 2.00 +/- 0.34 respectively, were significantly decreased (P < 0.05 or P < 0.01).

CONCLUSIONPDTC could attenuate paraquat-induced up-regulation of TGF-beta(1) and its mRNA expression, MMP-2 and TIMP-1 mRNA levels, which indicates that PDTC may exert its protective effects on paraquat-induced pulmonary damage by alleviating the earlier inflammation damage and adjust-ing the balance between MMPs and TIMPs. However, further studies are still warranted to investigate and clarify the underlying mechanisms involved in this complicated process.

Orthotopic liver transplantation has proven to be effective in the treatment of a variety of life-threatening liver diseases, however, the limitations of donated organs available and long-term immunosuppression provided an impetus for developing alternative therapies. Cell replacement strategies have been one major effective approach for overcoming the obstacles of organ transplantation in recent years. The exogenous cells should be able to proliferate and differentiate into mature hepatic cells after grafting. Use of mature hepatocytes is also hampered by limited tissue source and inability to proliferate and maintain the function for a long term in vitro. Embryonic stem cells are immortal and pluripotent and may provide a novel cell source for potential cell therapy. This review summarizes the mechanisms of controlling early liver development and hepatic differentiation of visceral endoderm in embryoid bodies, and provides an overview of diverse differentiation systems in vitro and in vivo that were applied to hepatic research in recent years. Several studies have demonstrated that ES cell-derived hepatocytes can incorporate into liver tissue and function in vivo , but a few of them have shown complete restoration of liver function after transplantation into mice with liver diseases. Further studies should be made to exploit efficient methods and clinical applications of hepatocytes derived from ES cells in the future. In addition to clinical transplantation for treatment of liver diseases, ES cells can provide a valuable tool for drug discovery applications and study on of molecular basis of hepatic differentiation.

OBJECTIVETo study the impact of abdominal obesity on the production of male reproductive endocrine hormones.

METHODSThis study included 342 male patients at the andrology clinic, aged 19 -47 years and higher than 160 cm. We measured their waistlines, hiplines and waist-hip ratio, detected the levels of serum estradiol (E2), testosterone (T), follicle-stimulating hormone (FSH), luteinizing hormone (LH) and free testosterone (FT) by chemiluminescence and radioimmunoassay, and analyzed the correlation of the waist-hip ratio with the levels of reproductive endocrine hormones. Abdominal obesity was defined as the waist-hip ratio > 0.9.

RESULTSIn the 342 male patients, there were 62 cases of abdominal obesity and 280 cases of the normal somatotype (waist-hip ratio < or = 0.9). The waist-hip ratio was negatively correlated with the T level (r = -0.163, P = 0.003) and the T/LH ratio (r = -0.13, P = 0.02). Both the T level and T/LH ratio were significantly reduced in the abdominal obesity patients ([14.51 +/- 4.53] nmol/L and 2.26 +/- 0.36) as compared with the normal somatotype controls ([17.21 +/- 4.23] nmol/L and 4.61 +/- 0.19) (P < 0.05).

CONCLUSIONThe waist-hip ratio has a significant negative correlation with the T level and T/LH ratio, and the serum T level is significantly lower in men with abdominal obesity than in those of the normal somatotype.
