Chinese Journal of Biochemical Pharmaceutics 2017;37(8):224-225
Objective To investigate and analyze the influence of psychological intervention on the compliance of patients with hepatitis B treated with pegylated interferon alpha 2a. Methods 100 patients with hepatitis B treated in our hospital from April 2014 to October 2016 were selected and randomly divided into the control group and the experimental group, with 50 patients in each group. The experimental group and the control group patients were treated with pegylated interferon alpha 2a treatment, treatment time was 48 weeks, no other antiviral therapy. The control group was given routine care, and the experimental group was given psychological intervention on the basis of the control group. The treatment compliance of the two groups was compared and analyzed. Results After the corresponding treatment, the score of mental health in the experimental group was (9.94±2.01) points, and the score of mental health in the control group was (6.41±2.27) points. The scores of mental health in the control group were significantly lower than those in the experimental group, with statistical difference (P<0.05). Among the patients in the experimental group, three patients had poor compliance, 20 patients had good compliance, and 27 patients had good treatment compliance, and the compliance rate was 94%. Among the patients in the control group, 15 patients had poor compliance and the rate of compliance was 70%. The rate of good treatment compliance in the control group (70%) was significantly higher than that in the experimental group (94%), with statistical difference (P<0.05). Conclusion Ppsychological intervention can significantly improve the treatment compliance of pegylated interferon alpha 2a in patients with hepatitis B, and improve the quality of life of patients, so it has the clinical significance of further promotion and application.

IL-17 is the cytokine secreted by the subgroup of CD4+T cells named Th17.The differentiation,proliferation and cytokine secretion of Th17 are regulated by TGF-?,IL-6,IL-15 and IL-23.IL-17 modulates the production and secretion of proinflammative factors,CXCs,affecting the transfer of neutrophil,the activation and the absorption of bone.It suggests that IL-17 also plays an important role in the pathogenesis of autoimmune diseases.

BAFF is an essential ligand essential for survival and differentiation of peripheral B cells. By interacting with three receptors, BAFF can promote B cell maturation and class switching, enhance humoral immunity and T cell co-stimulation. Over-expression of BAFF leads to autoimmune diseases such as systemic lupus erythematosus (SLE) in mouse model. Treating the mice model with BAFF antagonists can slow-down disease progression and enhance survival rate. Moreover, in some SLE patients serum level of BAFF is elevated and correlated with serum anti-dsDNA titer. The preliminary clinical trial of anti-BAFF monoclonal antibody has shown to be safe and effective. BAFF antagonists are promising therapeutic drugs for SLE.

Objective:To imestigate the effect of Shenxiong injection on neuronal aooptosis and Fasassociated death dormin protein(FADD)and its mRNA expression after ischernia-reperfusion in rats.Methods:Atotal of 100 SD rats wgre randomly allocated into normal(n=10),sham-operation(n=10),cerebral ischemia-reperfusion(n=40),and Shenxiong injection(n=40)groups.A model of middle cerebral wtery occlusion was induced by suture method.The neuronal apoptosis was detected by the TUNEL assay.The expressions of FADD protein and mRNA were detected by inmmnohistochemical staining and reverse tramcription-polymerase chain reaction(RT-PCR),respectively.Results:As compared with the normal and sham-operation groups.the numbers of apoptotic cell in the cerebral ischemia-reperfusion group were increased significantly(P<0.01),and the expressions of FADD protein and mRNA were enhanced significantly(all P<0.01).As compared with the ceretral ischemia-reperfusion group,the numbers of apoptotic cell were decreased significantly (P<0.05,P<0.001),and the expressiom of FADD protein and mRNA were reduced significantly in the Shenxiong group(P<0.05,P<o.001).Convlusions:Shertxiong injection may inhibit the neuronal apoptosis after ischemia-reprfusion in r-cas by down-regulaftng the expression of FADD.

OBJECTIVE To investigate the distribution and the resistance variance tendency of the pathogenic bacteria isolated from the blood cultureing specimens collected during the period of 2002-2005.METHODS A retrospective analysis was made to the blood cultureing results during the period of 2002-2005 with WHONET 5.1 software.RESULTS Gram-negative rods were the predominant bacteria which caused sepsicemia,the isolated rates of Escherichia coli,Klebsiella pneumoniae and Staphylococcus aureus were the most high during the period of 2002-2004 but the S.epidermidis and S.hominis were also the important pathogenic ones which caused blood stream infection.Vancomycin and the teicoplanin were the most effective to the Gram-positive bacteria,and the imipenem and the cefepime were the most effective to the Gram-negative ones.CONCLUSIONS It′s important to strengthen the blood cultureing for blood stream infection patient.

Objective To explore the damage of spiral ganglion neurons(SGNs),the protective effects of different dosages of healthy ear compound (HEC)from traditional Chinese medicine(TCM) against age-induced SGNs degeneration and its possible mechanism in spiral ganglion neurons(SGNs)of C57BL/6J mice.Methods Totally 36 C57BL/6J mice just after ablactation were randomly divided into four groups.Normal control group (n =6)drank tap water daily from ablactation to 2 months old.Ageing-related SGNs apoptosis control group(n=12)drank tap water daily from ablactation to 7 months old.High dose TCM group(n=12)at drank 3.65 g/kg/d of HEC from ablactation to 7 months old.Low dose TCM group(n=6)drank 0.91 g/kg/d of HEC from ablactation to 7 months old.The animal cochleae were immediately removed at the termination of the experiment.In each group,the cochleae of 6 animals were used for paraffin embedding,slicing and toluidine blue staining to observe neuronal morphological changes.The caspase-3 mRNA expression study was performed by real-time PCR technique in 6 cochleae of High dose TCM group and ageing-related SGNs apoptosis control group.Results The morphological structure of cochlear SGNs represented healthy and normal density in normal control group at 2 months old.In contrast,amount or density of SGNs in cochlear basilar part was significantly damaged and reduced in ageing-related SGNs apoptosis control group at 7 months old(P< 0.001).But the high dose TCM group at 7 months of age was similar to the normal control group at 2 months old in morphological structure,amount or density of SGNs(P>0.05).The low dose TCM group was significantly different from other 3 groups in amount or density of SGNs (P<0.001).However,SGNs in the middle part and apical part showed integrity in each group.In addition,the expression level of caspase-3 in the cochlea of high dose TCM group was also obviously different with age-related SGNs apoptosis control group(P<0.01) Conclusions Ageing-related damage of SGNs in C57BL/6J mice begins from the base of cochlea and progresses towards the apex.The HEC of TCM could significantly protect SGNs against age-induced apoptosis in SGNs.The efficacy of the high dose TCM is better than that of the low dose TCM.Its SGNs protective mechanisms might be related to involving the caspase-mediated cell apoptotic pathway.

The purpose of this study was to investigate the cytotoxicity of the nickel ion and provide with basic data for the biological evaluation of those medical devices containing nickel. Seven cell lines were chosen. They were L929, h9c2(2-1), 293[HEK-293], hFOB1.19, THLE-3, H9 and IM-9 respectively. According to the principle of biological evaluation of medical devices, MTT method was chosen to test the cytotoxicity in different concentrations of nickel ion. For each cell line, the relative growth rate (RGR) was obtained and the cytotoxic grade was classified. Besides, IC50 values were calculated. As a result, it was found that the sensitivity was different among all cell lines. H9 was the most sensitive one, while the L929 was the most tolerant one. The concentration which is not above 1.25 mg/L was safe for all seven cell lines, because the cytotoxicity for all cells exposed in this concentration were not higher than grade 1. According to the criteria for medical devices, the concentrations not above 5 mg/L were safe for L929 cells. This result helps us to roughly assess the cytotoxicity and systematic toxicity caused by nickel contained in medical devices.
