Glioma is a tumor with a high incidence of intracranial tumor. Because of its high degree of malignancy, strong invasiveness and high mortality, the current conventional treatment cannot achieve the desired therapeutic effect, which greatly affects the quality of life of patients. As a protein with the functions of anti-proliferation, anti-angiogenesis and anti-invasion, interferon is widely used in the treatment of all kinds of tumors in clinic. Many studies have shown that interferon plays an important role in the occurrence and development of gliomas. To explore the mechanism of interferon and its related signal pathway in the process of glioma invasion, and to study the new treatment of glioma is very necessary in clinical treatment.

Objective To investigate the trend of cytokines in patients with hemophagocytic lymphohistiocytosis (HLH) and analyze its significance.Methods 16 patients with HLH from January 2011 to May 2013 were selected.The patients were divided into remission group and death group by prognosis.Serums of the two groups were collected when they were hospitalized and at 7 th,14 th,21st,28th and 42nd day during chemotherapy,and they were fractionated HLH 1-6 groups and HLH a-d groups again,then the levels of IL-18,IL-10,IL-12,NF-κB,TNF-α and neopterin were tested by enzyme linked immuno sorbent assay (ELISA) to analysis their trend.Results The levels of all of cytokines in the remission group declined with chemotherapy,the difference between HLH1 group and another HLH groups was statistically significant (P ＜ 0.05).In the death group,the levels of NF-κB,IL-12 and neopterin had no downward trend with chemotherapy,and the difference between HLHa group and another HLH groups was not statistically significant (all P ＞ 0.05).The level of TNF-α declined with chemotherapy,and the differences between HLHa group and HLHc group,HLHa group and HLHd group were statistically significant (P =0.049,0.000).The level of IL-10 declined sharply in the first week of chemotherapy,and the difference between HLHa group and HLHb group was statistically significant (P =0.00).The level of IL-18 declined after the 2nd-weeks' chemotherapy,and the differences between HLHa group and HLHb group,HLHa group and HLHc group were statistically significant (P =0.03,0.02).Conclusions In the remission patients,the levels of serum IL-18,IL-10,IL-12,NF-κB,TNF-α and neopterin declined after chemotherapy.In the death patients,the downward trend is not obvious.It was preliminarily confirmed that the prognosis of HLH is related to the trend of cytokines during chemotherapy.

Objective:To observe the effect of shift work on the stability of the circadian clock and insulin sensitivity in non-overweight/obese individuals with normal blood glucose, and explore underlying connection.Methods:Female shift working nurses in the Department of Blood Transplantation and non-shift working nurses in the Health Management Center in the First Affiliated Hospital of Zhengzhou University were divided into shift worker group (SW group) and non-shift worker group (NSW group). Serum inflammatory factors [interleukin-6 (IL-6), tumor necrosis factor-α(TNF-α)], adipokines (adiponectin, leptin, chemerin, visfatin), and melatonin levels were measured using enzyme linked immunosorbent assay (ELISA). Realtime fluorescence quantitative PCR was performed to detect peripheral blood circadian clock genes circadian locomotor output cycles protein kaput(Clock) and brain and muscle ARNT-like protein 1(Bmal1). Cortisol and fasting insulin were measured by chemiluminescent microparticle immunoassay, and HbA 1C was measured by capillary electrophoresis. In addition, visceral fat area (VFA) was assessed with bioelectrical impedance analyzer, and mid-sleep time composite phase deviations (CPD) was calculated based on the International Physical Activity Short Questionnaire. Results:SW group had lower serum level of melatonin ( P=0.023) and higher cortisol ( P=0.001) than the NSW group, and altered mRNA expression of Clock and Bmal1 ( P=0.034, P=0.047). Fasting blood glucose and HbA 1C in the SW group, although in the normal range, had been higher than in the NSW group ( P=0.011, P=0.033). Although body mass index was normal in SW group, VFA had been higher than that of the NSW group ( P=0.010). And homeostasis model assessment for insulin resistance (HOMA-IR), IL-6, TNF-α, leptin, chemerin, and visfatin were significantly higher in the SW group than NSW group ( P=0.033, P=0.012, P=0.001, P=0.011, P=0.021, P=0.007). In addition, adjusting for body mass index and activity factors revealed a significant positive correlation between CPD and VFA ( r=0.434, P=0.049), inflammatory factors IL-6 ( r=0.514, P=0.017) and TNF-α ( r=0.700, P<0.001) and pro-inflammatory adipokines leptin ( r=0.473, P=0.030), chemerin ( r=0.439, P=0.047), visfatin ( r=0.521, P=0.015). Conclusion:Shift work can affect circadian clock, with increased visceral adiposity, pro-inflammatory adipokines, inflammatory factors and decreased insulin sensitivity in women without overweight/obese.

Objective: To examine college students awareness of AIDS (acquired immunodeficiency syndrome) and HIV (human immunodeficiency virus), as well as their willingness to undergo testing, and to provide guidance for further education targeted towards AIDS prevention. Methods: The respondents were selected from two companies of military training camps in 4 universities in Fengtai District of Beijing using cluster sampling, and a questionnaire was used to obtain relevant information among 1 248 college freshmen. The content of the questionnaire included basic information about the students, awareness of AIDS, and willingness to undergo testing. Results: A total of 87.18% students were familiar with AIDS related knowledge, and 62.98% students intended to have HIV tests in the future. Willingness to be tested for HIV was higher among not local students (67.39%) than among local students(55.65%)(χ 2=17.32, P<0.05). The willingness to get HIV testing was higher among students who had an understanding of AIDS (65.26%) than among those who lacked an awareness(47.50%)(χ 2=18.87, P<0.05). In terms of the willingness to be tested for HIV, the main concerns focused on personal privacy (23.24%) and the cost (18.59%). Multivariate regression analysis showed that improving students awareness of five of the items related to a basic knowledge of AIDS may increase their willingness to get HIV testing(P<0.05). Most students indicated a preference to get HIV testing at a hospital (68.51%) or at the Centers for Disease Control and Prevention(42.79%). Conclusion The willingness to get HIV testing can be increased by launching an AIDS health education program that targets weak knowledge points with respect to AIDS awareness.

Objective To analyze the effects of Hual qi huang granules on children with mycoplasma pneumoniae pneumonia.Methods A randomized,multicenter parallel controlled clinical trial was carried out.A total of 3 000 cases of hospitalized children with mycoplasma pneumoniae pneumonia were selected.All of them were given treatment for mycoplasma pneumoniae pneumonia with macrolide antibiotics and symptomatic treatment.They were randomly divided into 2 groups:research group and control group.The children of research group were give oral Huai qi huang granules for three months.According to the classification of pneumonia,these two groups were divided into:lobar pneumonia research group,lobar pneumonia control group,lobular pneumonia research group,lobular pneumonia control group.The hospitalization duration of fever,length of hospital stay,the absorption area of lung inflammation and pneumonia severity sores were observed.The frequency of upper respiratory infections,bronchitis,pneumonia were observed in 3 months after discharge.Results 2 378 cases were investigated.The hospitalization duration of fever,length of hospital stay of research group were significantly shorter than that of in control group (P ＜ 0.001).The children with lobar pneumonia,2 weeks after treatment,the absorption of consolidation of the lobar pneumonia research group is significantly better than lobar pneumonia control group (P ＜0.001).After two weeks treatment,the pneumonia scores of lobar pneumonia research group is lower than lobar pneumonia control group (P ＜ 0.05).Followup of 3 months after hospital discharge,frequency of upper respiratory infection and bronchitis of research group,were significantly lower than that of control.In addition,appetite increased significantly in research group than control (P ＜ 0.001).There are 21 cases with drug associated adverse reactions (mild diarrhea),including 12 cases of research group,9 cases of control group,and there was no statistical significance (P ＞0.05).Conclusion Standard treatment combined with oral Huai qi huang granules in the treatment of mycoplasma pneumoniae pneumonia,can significantly shorten hospitalization duration of fever,length of hospital stay and reduce the severity score of pneumonia.Three months oral Huai qi huang granules can significant reduce the frequency of respiratory infections and bronchitis,also can increase patients appetite,and be safe.
