Objective To investigate the outcome of allergen skin prick test in children with bronchial asthma,and propose prevention strategy.Methods Sensitinogen prick test on the skin was applied on 200 children who were in asthma clinic of our hospital between Mar 2007 and Oct 2010.Then,the distribution of sensitinogen and their correlation with age and sex were analysed by SPSS 17.0.Results (1) The positive rate of sensitinogen prick test in 200 children with asthma was 72.5%(145/200).The positive rate of inhalant allergen and ingestion allergen were 62.5%(125/200),14.0%(28/200),respectively,of which dermatophagoides farinae,dermatophagoides pteronyssinus,outdoor mould,mugwort,cat epidermis,tree Ⅰ,egg,milk were 36.5%,40.5%,19.0%,17.0%,17.0%,13.0%,8.0%,5.5% respectively.(2) The frequency of sensitivity to cat epidermis,mugwort,outdoor mold and tree Ⅰ increased with age and the frequency of sensitivity to egg and milk decreases with age.The sensitivity rate to all other allergens had no relation with sex.(3) The severity of sensitivity to dermatophagoides farinae,dermatophagoides,ragweed and pigweed increased with age,while severity of sensitivity had no significant relation with sex among the 18 kinds of allergens.Conclusion Dermatophagoides farinae,dermatophagoides pteronyssinus,outside mould,mugwort,tree Ⅰ,cat epidermis,egg and milk are the major allergens in children with bronchial asthma,who should avoid contact with these facters.

Recently,there had been many researches about the effects of brain nat-riuretic peptide(BNP)and N-terminal pro-brain natriuretic peptide(NT-proBNP)on diagnosis and differential diagnosis of cadiovascular disease,risk classification,assessment of the treatment,prognosis and screening.Some results had been applied to clinical.This article reviews the progress of BNP and NT-proBNP on pe-rioperative monitoring for congenital heart defect.

For the patients with early non-small cell lung cancer (NSCLC) who can tolerate surgery,surgery remains the standard treatment.For that patients who can not tolerate surgery,a large number of studies have shown that stereotactic body radiothery (SBRT) plays an indispensable role in the treatment of early NSCLC.

Objective Analysing the potential relationship of mismatch repair protein MLH3 gene C2531T mutation with oligospermia and azoospermia cases. Methods Using MLH3 C2531T as an example to establish a method of tetra-primer amplification refractory mutation system-PCR (4P-ARMS-PCR); We chose 81 cases of oligospermia, azoospermia patients and 80 normal controls, detecting MLH3 C2531T both using 4P-ARMS-PCR and PCR-RFLP; randomly to select 20% samples to sequence. Results The results suggested higher prevalence of CT + TT genotypes in patients as compared to the controls and association of T allele with disease (P <0. 01); PCR-RFLP results , 4P-ARMS-PCR results and sequence results are fully consistent. Conclusion 4P-ARMS-PCR can be a fast, easy-operating and accurate technology for detection of gene mutation of single nucleotide polymorphism (SNP) ; MLH3 C2531T polymorphism is related to oligospermia and azoospermia.

Objective:To examine relationship of postpartum depression with life events and social support. Methods: Thirty patients with postpartum depression and 32 normal controls were rated by a life events scale and a social support scale. Results: The number of negative life events were found to be higher in patients with postpartum depression as compared to normal controls. Social support of patients with postpartum depression was also found to be lower than their normal counterparts. Conclusion: Negative life events and deficient social support were significantly related to postpartum depression.

Objective The aim of this paper is to develop a holistic mathematical model to quantify the correlation between skin thermal sensation and noxious stimuli,since skin thermal pain is one of the most common problems in everyday life and the understanding of the underlying physical mechanisms is still not clear.Methods The model is developed by considering the biothermomechanical behaviour of skin tissue and by incorporating the current understanding of biophysical and neurophysiological mechanisms of pain sensation.Results The proposed model consisted of three interconnected sub-models: peripheral modulation of noxious stimuli,which converts the energy from a noxious thermal stimulus into electrical energy via nerve impulses;transmission,which transports these neural signals from the site of transduction in the skin to the spinal cord and brain;and modulation and perception in the spinal cord and brain.The model predictions agree well with existing experimental data.Conclusion With this model,a direct relationship has been built between the level of thermal pain sensation and the character of noxious stimuli.

Diagnostics is the bridge from basic medicine to clinical medicine.For the students contacting the clinic for the first time,we take measures to cultivate the consciousness of showing love to patients and dedicating yourself to work.It is beneficial to cultivate the students'ability in clinical practice.

OBJECTIVE: To analyze the current situation and developing trend of drugs used in 10 hospitals of Hunan Province from 1996 to 2000, and to serve as reference for drug production, marketing and clinical application .METHODS:The sum of money and percentages of different kinds of drugs used each year were added up separately.RESULTS: The sum of money of drugs consumed was increasing at a rate of 18% each year.About 40% of the money was spent on anti - infective drugs and 20% on imported drugs.CONCLUSION: The sum of money of drugs consumed will grow year by year .The clinical use of drugs will be more rational and of more choices,but the sum of money spent on imported drugs will decrease.

Ischemic reperfusion is the common mechanism of some chronic diseases such as type 2 diabetes,coronary heart disease,hypertension,and so on.Previous studies of insulin resistance is mainly focused on the relationships of these chronics,while now,in recent years,the research between the insulin resistance and ischemic reperfusion has gradually become one of the new and hot points,closely related to the patient's prognosis.In this paper,we will review the insulin resistance and ischemic reperfusion according to the reported literature review.

Objective: To explore health resource allocation and optimization and evaluate the clinical departments efficiency in hospital. Methods: Taking a three level of first-class hospital in Beijing for example, the method of data envelopment analysis (DEA) was used for building a DEA model of clinical departments efficiency in hospital. Results: Based on the results of the DEA model, we drawn the technical efficiency and scale efficiency of the target clinical departments, obtained input redundancy rates and output deficiency rates of the non-effective decision-making units. Conclusion:By DEA evaluation results, the input redundancy and output deficiency of the target clinical departments are found. From the perspective of optimizing hospital resource allocation, measures to improve the hospital operational performance are proposed. There is important significance to improve the comprehensive competitiveness of the hospital.
