Objective To study clinical manifestations and imagine features (CT and MRI) on toxic encephalopathy after inhaling heroin. Methods 13 patients with toxic encephalopathy induced by inhaling heroin were observed and analyzed on its clinical and imagine features (CT and MRI).Results 13 patients all were male, and were intoxicated by way of inhaling heroin vapour. Nine cases had appearances of clinical manifestations during abrupt abstinence. The main clinical manifestations of the disease were of the sub-acute diffuse cerebral lesions, especially of early mental symptoms and cerebellum ataxia. The CT of all 13 cases showed multiple white matter lesions involving in the frontal, parietal, occipital,temporal, and cerebellum hemisphere dentate nucleus. There was no occupational mass shown in general. The MRI of 6 cases showing focus was the same as of the CT. Conclusion The diagnosis of HTE should be dependent on the definite inhaling heroin vapour and their clinical features and neuroradiological appearance. CT should be valuable for the diagnosis of HTE, and the MRI as well. Corticosteroids show less therapeutic effect on such diesease.

Conclusion The significantly increasing of fat tissue in all parts of body is a major cause of change of body composition components in obesity. FAT in the trunk increases more obviously than that in other parts of the body in both males and females. The change of distribution of FAT and LEAN can obviously influence BMD.

Objective To investigate the effects of 5-fluorouracil (5-FU) on the distribution, pro-portion and immunosuppressive activities of myeloid-derived suppressor cells (MDSCs) in a mouse model of liver cancer.Methods Orthotopic transplantation of H22 cell line was performed to establish the mouse model of orthotopic liver cancer.Forty mice were randomly divided into four groups (n=10) on the 7th day after transplantation.Three different doses of 5-FU (10 mg/kg, 30 mg/kg and 50mg /kg) and 0.4 ml of PBS were respectively given to the mice in each group for 10 consecutive days .A control group without canc-er cell transplantation was set up correspondingly .The distribution of MDSCs in mice liver tissues was detec-ted by immunohistochemistry .The proportions of MDSCs in spleen tissues were tested by flow cytometry . The levels of IFN-γand Arginase-I ( Arg-I) in serum samples were analyzed by enzyme-linked immunosor-bent assay.The activities of nitric oxide synthetase (NOS) in serum samples were tested by chemical colori-metry.The proliferation of T lymphocytes was assessed by 3-(4,5-Dimethylthiazol-2-yl)-2, 5-diphenyltet-razolium bromide (MTT) test.Results 5-FU reduced the tumor size and alleviated the adhesion between liver tissues and abdominal cavity in mice with liver cancer in a dose-dependent manner .The proportions of MDSCs in liver and spleen tissues from mice in four model groups were significantly higher than those in con - trol group (P<0.05).The highest proportions of MDSCs were observed in PBS treated group , followed by 10 mg/kg of 5-FU treated group , 30 mg/kg of 5-FU treated group and 50 mg/kg of 5-FU treated group .Ex-cept for comparing between PBS treated group and 10 mg/kg of 5-FU treated group, there were significant differences with the proportions of MDSCs in liver tissues among other groups (P<0.05).The levels of Arg-I and the activities of NOS in mice with liver cancer were higher than those in control group (P<0.05).The mice in PBS treated group showed the highest level of Arg-I and the strongest activities of NOS that were de-creased as concentrations of 5-FU increased( P<0.05).The levels of IFN-γin serum samples from mice with liver cancer were lower than those in control group , and the lowest level was detected in PBS treated group.IFN-γlevels were increased as concentrations of 5-FU elevated.Except for comparing between PBS treated group and 10 mg/kg of 5-FU treated group , significant differences with the levels of IFN-γin serum samples (P<0.05) were observed among other groups .No significant differences with the proliferation of T cells were observed among all groups after 24 hours of culture (P>0.05),but that were decreased in model groups than those in control group after 48 hours of culture (P<0.05).T cells from mice in PBS treated group showed the lowest level of proliferation .T cell proliferation was enhanced upon the treatment of 5-FU in a dose-dependent manner .Except for comparing between PBS treated group and 10 mg/kg of 5-FU treated group, significant differences with T cell proliferation were observed among other groups (P<0.05).The proportions of MDSCs in liver and spleen tissues were positively correlated with the levels of Arg -I and the activities of NOS, but negatively correlated with IFN-γlevel and T cell proliferation at the time point of 48 h.Conclusion To a certain extent , 5-FU could reduce the numbers of MDSCs in liver and spleen tis-sues from mice with liver cancer , inhibit immunosuppressive activities of MDSCs and restrain the growth of the tumor in a dose-dependent manner .

Objective To investigate the effect of education in pregnant women’s school on primipara mode of delivery and puerperal behavior.Methods Two hundred and twenty cases who delivered in our hospital and paid postpartum visits were divided into observation group and control group equally according to whether they had attended the pregnant women’s school.The observation group included those having attended the school and the control those who had not.The two groups were compared in terms of primipara mode of delivery and puerperal behavior.Results The rates of maternal vaginal delivery and cesarean section rate in observation group were 71.8%and 28.2%,both significantly higher than those of the control group(52.7%and 47.3%)(P<0.01).The rate of caesarean section due to social factors in the observation group was significantly lower than that of the control group(P<0.05).Besides,the observation group had higher rates of puerperiumal shampoo, showering, eating vegetables and fruits,brushing,use of air-conditioners than the control group did(all P<0.01).Conclusions Prenatal maternal health education in the pregnant women’s school affects puerperous behavior.It suggests that prenatal parturients actively participate in related education on maternal health care,which can help establish a good pregnancy and puerperium maternal behavior,reduce maternal cesarean section and thus help them live through puerperium.
