comparison study on the clinical effects of foscarnet sodium injection and interferon on human immunodeficiency virus-infected patients complicated with herpes zoster

To compare the clinical effects of foscarnet sodium injection and interferon on human immunodeficiency virus [HIV]-infected patients complicated with herpes zoster. Ninety HIV-infected patients complicated with herpes zoster were divided into a treatment group and a control group that were both treated routinely first. Then the control group and treatment group were administered with interferon and foscarnet sodium injection respectively for four consecutive weeks. After four weeks, the effective rates of the treatment and control groups were 95.6% and 80.0% respectively, which were significantly different [P < 0.05]. The pain scores of the two groups were similar before treatment, but the scores of the treatment group were significantly lower than those of the control group two and four weeks after treatment [P < 0.05] as well as were significantly lower than those before treatment [P < 0.05]. The numbers of CD4+ cells and the contents of IL-2 of both groups two and four weeks after treatment significantly exceeded those before treatment [P < 0.05], with significant inter-group differences also [P < 0.05]. Two and four weeks after treatment, the treatment group scored significantly higher in physical activity, energy, sleep, social life and emotional reaction than the control group did [P < 0.05]. HIV-infected patients are prone to being complicated with herpes zoster. Compared with interferon, foscarnet sodium injection better improves the clinical outcomes by effectively relieving pain and by regulating immune mediated inflammatory diseases, thus boosting the prognostic quality of life

Plasma levels of N-terminal pro-brain natriuretic peptide and glycogen phosphorylase isoenzyme BB in neonates with asphyxia complicated by myocardial injury / 中国当代儿科杂志

<p><b>OBJECTIVE</b>To investigate the changes and the clinical significance of N-terminal pro-brain natriuretic peptide (NT-proBNP) and glycogen phosphorylase isoenzyme BB (GPBB) levels in neonates with asphyxia complicated by myocardial injury.</p><p><b>METHODS</b>Sixty-four neonates with asphyxia (39 mild, 25 severe) were enrolled. Of the 64 neonates, 30 had myocardial injury and 34 did not develop myocardial injury. Twenty-five healthy neonates served as a control group. Plasma levels of NT-proBNP and GPBB were measured using ELISA. Myocardial enzymes and cardiac troponin I were stimultaneously measured, and electrocardiography and chest radiographs were obtained.</p><p><b>RESULTS</b>The plasma levels of NT-proBNP and GPBB in neonates with myocardial injury were significantly higher than those in neonates without myocardial injury and in the control group (P<0.01). The neonates with severe asphyxia had significantly increased plasma NT-proBNP and GPBB concentrations compared to those with mild asphyxia and the control group (P<0.01). Spearman rank correlation analysis showed that plasma NT-proBNP level was positively correlated with plasma GPBB level in neonates with asphyxia. Plasma levels of NT-proBNP and GPBB were also positively correlated with plasma levels of CK-MB, CK and LDH (P<0.01).</p><p><b>CONCLUSIONS</b>Both NT-proBNP and GPBB can be used as biomarkers of myocardial injury in neonates with asphyxia. The measurement of plasma NT-proBNP and GPBB levels was useful in early identification of myocardial injury and severity evaluation in neonates with asphyxia.</p>

Changes of N-terminal pro-brain natriuretic peptide in neonates with myocardial ischemic injury / 中国当代儿科杂志

<p><b>OBJECTIVE</b>To investigate the changes of N-terminal pro-brain natriuretic peptide (NT-proBNP) in neonates with hypoxic-ischemic encephalopathy (HIE) complicated by myocardial ischemic injury.</p><p><b>METHODS</b>Thirty-five neonates with HIE (17 cases with concurrent myocardial injury and 18 cases without) were enrolled. Twenty healthy neonates were used as the control group. Plasma NT-proBNP levels were measured using enzyme immunoassay.</p><p><b>RESULTS</b>The mean plasma NT-proBNP levels in patients with myocardial injury (338.8 + or - 76.2 fmol/mL) were significantly higher than those in patients with non-myocardial injury (137.5 + or - 45.1 fmol/mL) and in the control group (113.7 + or - 53.6 fmol/mL) (p<0.01). The NT-proBNP levels in mild, moderate and severe HIE neonates were 141.3 + or - 41.6, 271.8 + or - 118.1 and 347.2 + or - 85.1 fmol/mL, respectively. Compared with the control group, the NT-proBNP levels in the moderate and the severe HIE groups significantly increased (p<0.01). There were significant differences in the NT-proBNP level among the mild, moderate and severe HIE groups (p<0.05). In patients with myocardial injury, the NT-proBNP levels significantly decreased in the convalescent phase compared with those in the acute phase (225.0 + or - 80.0 fmol/mL vs 338.8 + or - 76.2 fmol/mL (p<0.01).</p><p><b>CONCLUSIONS</b>Plasma NT-proBNP levels increase in neonates with HIE complicated by myocardial ischemic injury in the acute phase. Detection of NT-proBNP levels may be useful in the diagnosis of myocardial ischemic injury and the severity evaluation of HIE.</p>

Effects of Bone Marrow Mescenchymal Stem Cells Conditioned-Medium on Cortical Neuronal Apoptosis Induced by Hypoxia-Reoxygenation in vitro in Rats / 实用儿科临床杂志

Objective To observe the effects of bone marrow mesenchymal stem cells(BMMSCs) conditioned-medium (B-CM) on apoptosis in cultured cortical neurons after hypoxia-reoxygenation in vitro in rats.Methods BMMSCs were isolated,cultured and expanded,the culture me-dium was substituted by new medium that contain no serum when cells grew to 90% confluence.After cultured for 24 hours,the medium was collected as B-CM.Cortical neurons of mouse cultured for 8 days were divided into three groups:normal control groups,hypoxic group,B-CM disposed groups.Cell viability were detected by 3-(4,5-dimethlthiazd-2-yl)-2,5-diphenyltetra-zoliu bromidel (MTT) methods and the apoptosis of neurons was examined by flow cytometry and telemicroscopy on hypoxia for 0,6 hours and hypoxia-reoxygenation for 24 hours,respectively.Results Compared with control group,hypoxia for 6 hours could decrease cell viability,hypoxia-reoxygenation for 24 hours increased the cell apoptosis ratio remarkably(P

Study Progress on Relationship of Transforming Growth Factor-?_1 and Airway Remodelig in Asthma / 实用儿科临床杂志

Transforming growth factor-?1 (TGF-?1) was reported to play an important role in the pathogenesis of asthma in many stu-dies.It can stimulate the growth of fibroblast and give rise to fibrosis of lung tissues.Many scholars think that TGF-?1 is closely related to airway remodeling.It is a breakthrough to aim at TGF-?1 to find a way to intervene remodeling in asthma.Glucocorticoid (Dexamethasone and Budesonide) can have an impact in some extent to airway remodeling.In addition,interferon-? and some traditional chinese medicine such as ligustrazine,tripterygium wilfordii and ginkgo maybe effective,they all may ameliorate the progression of airway remodeling following redu-cing partial airway TGF-?1 expression.

Effect of Dexamethasone on Excitatory Amino Acid and Monoamine Neurotransmitter in Cerebral Tissue of Neonatal Rats with Hypoxia-Ischemia / 实用儿科临床杂志

Objective To explore the value of dexamethasone(DEX) for neuronal cell injury and death by observing the effect of DEX on excitatory amino acid(EAA) and monoamine neurotransmitter in cerebral tissue of neonatal rat with hypoxia-ischemia.Methods Hypoxic-ischemic neonatal rat models were established,the levels of EAA and monoamine neurotransmitter in cerebral tissue were analyzed by using capillary electrophoresis and fluorospectrophotometry method.The rats were divided into 4 groups: small dose DEX group pre-treated with DEX(0.5 mg/kg) prior to hypoxia-ischemia,large dose DEX group pre-treated with DEX(10 mg/kg) prior to hypoxia-ischemia,HIE group and shamful operation group.Results The levels of EAA and monoamine neurotransmitter contents in HIE group were significantly higher than those in shamful operation group(P0.05).EAA contents of large dose DEX group greatly decreased compared with HIE group (P
