Objective To investigate the effect of Platelet-activating factor(PAF)in pathogenesy of asthma in high altitude Methods ELISA and other methods were used to detect the quantity of platelet(PLT)and the level of serum platelet-activating factor(PAF)in the plain control group、the plateau control group and the plateau asthma patients group.Results The quantity of PLT in plain control group and plateau control group were significantly lower than that of plateau asthma patients group.(P

Objective To investigate the influencing factors of medication compliance of glucocorticoid for patients with interstitial lung disease (ILD). Method The outline in-depth interviews with 15 patients with ILD was done using content analysis method, and the influence factors of patients medication compliance were analyzed. Result The influence factors of medication compliance in ILD patients can be summarized as the following three themes: patients′individual factors, factors related to medical and absence of social and family support. Conclusion Nurses should master the influencing factors of hormone medication adherence in ILD patients, ready to take appropriate intervention measures, improve the medication compliance in patients with ILD hormone and promote their rehabilitation.

ObjectiveA method was proposed for the determination of the concent of total glucoside of peaony(TGP) fromPaeonia lactifloriaPall. by UV spectrophotometry.MethodsBased on the extract with 80% acidities alcohol, extracted by aether and n-butyl alcohol, TGP was obtained fromPaeonialactifloriaPall.. The determination was established with paeoniflorin which was the main component of TGP as a contrast by UV spectrophotometry at 230 nm.ResultsA good liner relationship between concentrationof paeoniflorin and its absorbance was obtained,and the liner range was between 0.040 2~0.201 1 mg/ml. The averagerecovery was 101.81%.ConclusionThis method is simple rapid and reliable. It could be used for the semi-quantitative determination of TGP of paeony in paeonialactifloria pall..

OBJECTIVETo explore the effect of Penqiangyan Granule (PG) on the immunity of patients with chronic pelvic inflammatory disease (CPID) of blood stasis and Shen-deficiency syndrome (BSSDS) type.

METHODSSixty patients were randomly assigned to two groups: the treatment group treated with PG and the control group with Penyanjing Granule, 30 cases in each group. The treatment course was 4 weeks for both groups. The clinical efficacy, plasma levels of CD4 and CD8, and the serum levels of tumor necrosis factor-alpha (TNF-alpha) and interleukin-2 (IL-2) were measured before and after treatment.

RESULTSAfter treatment, the total effective rate in the treatment group and the control group was 96.7% and 63.3% respectively with significant difference between groups (P < 0.05); in the treatment group the plasma CD4, CD4/CD8 and serum IL-2 increased obviously, while the plasma CD8 and serum TNF-alpha decreased markedly (P < 0.05), all were significantly different with those in the control group (P < 0.05).

CONCLUSIONPG can improve the immune function and alleviate inflammation in CPID patients of BSSDS type.

Objective:To investigate the levels of serum leptin and their effect on Th 1/Th2 balance and the association between serum leptin levels and clinical manifestations in obese children with asthma.Methods: All 56 children with physician-diagnosed moderate-to-severe persistent asthma and 56 healthy controls were included.The children with asthma and without asthma were divided into two groups,obese (n=28) and non-obese (n=28) by body mass index,respectively.Asthma severity was assessed by the asthma symptom score.Peripheral blood samples were collected to determine the levels of leptin , IFN-gamma and IL-4.The results were correlated with the parameters studied.Results:Serum leptin levels were significantly higher in the obese asthma group than in the non -obese asthma group ,as well as being significantly higher in the children with asthma than in the controls ( P<0.01 ) , whereas IFN-gamma levels were significantly higher and IL-4 levels were significantly lower in the obese asthma group than in the non-obese asthma group( P<0.01 ).In addition, the obese asthma group showed higher asthma symptom scores and significantly lower FEV 1 (% of predicted) than did the non-obese asthma group(P<0.01).There was a significantly positive correlation between leptin ,IFN-gamma and IL-4 levels only in the obese asthma group ( P<0.01 ).Conclusion:Leptin is involved in the pathogenesis of asthma in obese and non-obese children ,and its effect is more pronounced in the former.In the presence of high leptin levels , only obese children with asthma exhibited Th1 polarization,with higher IFN-gamma levels and greater asthma severity.

Objective To investigete the changes of neurons in cortex and hippocampus of spontaneously hypertensive rat.Methods Systolic pressure,diastolic pressure and mean arterial pressure,heart rate were measured by caudal artery manometry in six-month old SHR and age-matched Wistar rats(control group).Neurons in frontal lobe,parietal lobe,temporal lobe,and hippocampal CA1,CA3 sub-field and the dentate gyrus were observed through Nissl staining.Results Systolic pressure,diastolic pressure and mean arterial pressure in SHR were significantly higher than that in control group(P

Objective To explore the nervous mechanism of intestinal function disorder after intestine congestion through observing the changes of acetylcholinesterase (AchE) neuron and nitric oxide synthase neuron (NOS) expression in nervous system of rat intestinal tract. Methods Sprague Dawley rats were divided into experimental groups (intestine congestion 20min and 60min group) and the control group. Then the spreading specimens of intestinal myen-teric plexus of ileums were collected and stained by AchE and nicotinamide-adenine dinucleotide phosphate-D (NADPH-d) histochemistry, to observe and compare the density of distribution and staining of AchE and NOS positive neurons. Result Compared to the control group, the number and positive expression of AchE positive neuron in intestinal myen-teric plexus of ileums in the experimental group rats decreased (P
