Objective To investigate the effect of thyroxine on elder patients with chronic heart insufficiency. Methods 82 elder patients with chronic heart insufficiency were divided into 2 groups randomly . 46 cases of observation group and 36 cases of control group. All of them were received routine treatment, including vasodilators, diuresis and cardiotonic etc anti-heart failure ways.The group of observation plus thyroxine (20mg/d oral,for 2 weeks ).Cardiac function degree,heart/lung ratio and change of cardiac ejection fraction(F) were observed before and after treatment. Results The value of EF,increased heart/lung ratio reduced,and function of heart were notably improved,as compared with those of the control group (P

Asthma is one of the most chronic airway inflammatory disease,threating the children's health.Bronchiolitis significantly increased the risk of childhood asthma,and many studies have focused on looking for the related factors between bronchiolitis and asthma in recent years.It may be helpful to understand the pathogenesis of the asthma,so as to find new measures for asthma's prevention and treatment.In present studies,bronchiolitis influenced the development of asthma in genetics,immunity,environmental factors and so on.So far,whether bronchiolitis directly causes the development of the childhood asthma,the prevention of bronchiolitis could reduce the asthma morbidity or not,both need more evidences yet.

Objective To evaluate the early diagnosis value of blood neutrophil gelatinase-associated lipocalin (NGAL) and interleukin-18 (IL-18) in patients with sepsis-induced acute kidney injury (AKI). Methods A prospective case controlled study was conducted. Fifty-six patients with sepsis but without renal disease admitted to intensive care unit (ICU) of Shanxi People's Hospital from April 2014 to April 2015 were enrolled. Blood lactic acid and acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score at ICU admission were recorded. The urine output, blood urea nitrogen (BUN), serum creatinine (SCr), NGAL, IL-18 and tumor necrosis factor-α (TNF-α) were continuously monitored for 48 hours. The patients were divided into AKI group and non-AKI group according to the diagnostic criteria of Kidney Disease: Improving Global Outcomes (KDIGO). The changes trend in above parameters between the two groups at different time points were compared. The early diagnostic value of NGAL, IL-18, and SCr for sepsis-induced AKI was evaluated by receiver operating characteristic curve (ROC). Results Compared with non-AKI group, with the time prolongation after ICU admission, the traditional parameters reflecting AKI urine output in sepsis-induced AKI group was decreased gradually, BUN and SCr were gradually increased, and a statistically significant difference was found at 12 hours between the two groups [BUN (mmol/L): 11.8±3.5 vs. 8.2±3.5, SCr (μmol/L): 88.6±11.3 vs. 74.0±11.0, both P < 0.01]; but the new indicators NGAL and IL-18 reflecting AKI had a statistically significant difference at 6 hours [NGAL (μg/L): 426.7±90.7 vs. 382.3±67.9, IL-18 (ng/L): 75.7±9.3 vs. 70.9±7.3, both P < 0.05]. It was shown that in AKI group, NGAL and IL-18 compared with BUN and SCr increased at least 6 hours ahead of schedule. The area under ROC curve (AUC) of 6-hour NGAL and IL-18 in patients with sepsis-induced AKI were 0.821 [95% confidence interval (95%CI) = 0.713-0.931] and 0.719 (95%CI = 0.584-0.853) respectively, superior to SCr (AUC = 0.677, 95%CI = 0.528-0.825). The cutoff value of NGAL was 363.58 μg/L, and the sensitivity and specificity were 88.0% and 86.7% respectively. Conclusions NGAL and IL-18 in the early prediction of sepsis patients with AKI are better than SCr, and NGAL was most sensitive. Therefore, NGAL can be used as an early biomarker for the diagnosis of AKI in patients with sepsis.

Bronchial asthma (also called asthma) is the most common chronic respiratory inflammatory disease in childhood.With the increased incidence of asthma in recent years,the guidelines for diagnosis and treatment of asthma have been also updated quickly at both domestic and overseas.Acute exacerbations of asthma will result in unscheduled medical attendances in emergency department or hospitalizations,and the severe one may be life-threatening,which brings a heavy burden to the families and society.Several guidelines,Meta analysis,and studies in treatment of childhood asthma exacerbations are reviewed in this article,so as to provide recommendations in the treatment of childhood asthma exacerbations for physicians.

Logistics supplies are essential for normal operations of hospitals,while effective management of hospital suppliers is key to optimizing the materials supplies.An evaluation system is built for both key suppliers and standby suppliers respectively.Based on such a system,a dynamic management mechanism is built to provide long-lasting supplier incentives,for competitive selection and elimination of the suppliers.These efforts enable the hospitals to pick the best suppliers by means of systems and regulations.

Ginsenosides are the main active components of medicinal herbs including Panax ginseng and Panax quinquefolium, which have potent effects of anti-tumor, anti-inflammatory, antioxidant and apoptosis inhibition. But the low content of ginsenosides limits its development and usage. At present, how to improve the production of ginsenosides by biological technology has been a new research focus. Some advances in the biosynthesis of ginsenosides by tissue culture and biotransformation have been made in recent years. So far at least twenty genes related to the biosynthesis of ginsenosides from Panax genus plants have been cloned and functionally identified, which has laid a good foundation for the study on the synthetic biology of ginsenosides. This review outlines recent advances in several aspects and is expected to provide a theoretical support to the thorough research of the pathway and regulation of ginsenosides biosynthesis.

ObjectiveTo estimate the effect of azithromycin on lung function and transforming growth factor β1(TGF- β1) in patients with idiopathic pulmonary fibrosis (IPF). MethodsOne hundred and ten patients with IPF were divided into two groups by random digits table. Patients in azithromycin group(60cases) were treated by azithromycin tablets and thoee in placebo group ( 50 cases) were treated by placebo tablets, and they were observed for 12 weeks. Lung function was detected at beginning and after 6,12 weeks' treatment. TGF- β1 was tested by ELISA, meanwhile patient's condition was observed. ResultsAfter 6 and 12 weeks' treatment, the forced expiratory volume in 1 second (FEV1), forced vital capacity (FVC), carbonmonoxide diffusion capacity (DLCO) in the two groups had no significant differences compared with those at beginning of treatment (P ＞ 0.05). After 12 weeks' treatment, the level of TGF- β1 in azithromycin group was significantly decreased compared with that at beginning and after 6 weeks' treatment (P ＜ 0.05) ,but there was no significant difference in placebo group (P ＞ 0.05). The ratio of acute exacerbation admission and infection was 8.3％(5/60) and 60.0％(3/5) in azithromycin group, 22.0％( 11/50) and 81.8％(9/11 ) in placebo group,and there were significant differences between the two groups(P ＜0.05 or ＜0.01). Conclusion Azithromycin may reduce the ratio of acute exacerbation admission and infection, decrease TGF- β 1 expression in patients with IPF by taking orally for a long time, but it may have no obvious effect on lung function.

Objective To determine the concentration of hepatocyte growth factor (HGF) in vitreous of diabetic retinopathy (DR) and investigate the result and influence of HGF in neovascularization in proliferative diabetic retinopathy (PDR). Methods The high sensitive sandwich enzyme linked immunosorbent assay (ELISA) was used to measure the level of HGF in vitreous of normal group for 10 eyes, simple DR group for 7 eyes, PDR without iridal neovascularization group for 24 eyes, PDR with neovascularization of iris group in 9 eyes, other retinopathy group associated with neovascularization for 8 eyes. Results The mean value of HGF level in vitreous of the former groups was: (3.3 ?1.9) ?g/L in normal group; (4.8?2.5) ?g/L in simple DR group; (13.0 ?5.2) ?g/L in PDR without iridal neovascularization group; (18.6?7.2) ?g/L in PDR with neovascularization of iris group; (12.1?8.9) ?g/L in other retinopathy associated with neovascularization group. Stastistics showed that HGF level in PDR group and other retinal diseases associated with neovascularization were significantly higher than that in normal group ( P
