Wheezing in infants and young children are common respiratory diseases, the incidence rate of it is increasing year by year. Viral infection of the respiratory tract is one of the most important provocative causes of infant wheezing disorders. Recent studies have discovered the relationship between Bocavirus and infant wheezing. To study the relationship between Bocavirus and infant wheezing will be important to prevent infant wheezing disorders.

Objective To analyze the clinical and histopathological features of 100 cases of scrotal Paget's disease. Methods Specimens were collected from 100 outpatients with scrotai Paget's disease evaluated in the Department of Dermatology, Huashan Hospital, Fudan University during the period of 1987-2004. Clincal data as well as findings in the examination with H&E staining, special staining and immunohisto-chemical staining were retrospectively assessed for these cases. Results Three types of tumor cells were observed in these specimens, including typical Paget cells (51 cases), mutinous or signet-ring cells ( 11 cases), small cells ( 18 cases). Mixed types of tumor cells were seen in 20 cases. Paget cells spread in the epidermis in three patterns (sparsely, intensively and classically). Tumor cells could extend down along the epithelium of follicles or sweat glands, ultimately broke through dermal-epidermal junction or the basal membrane of adnexa, and migrated into the dennis. Conclusions Histopathological examination is the most important clue to the diagnosis of scrotal Paget's disease. Histologically, it should he differentiated from superficial spreading malignant melanoma, skin iymphoma, pagetoid squamous cell carcinoma in situ and secondary scrotal Paget's disease.

Hepatocyte growth factor participates in many gynecologic and obstetric diseases such as gynecological tumor,endometriosis and hypertensive disorder complicating pregnancy by combination with its receptor c-Met.This article reviews the expression and mechanism of HGF in these diseases.

Objective To investigate the correlation between epicardial fat thickness (EAT) and the risk factors of coronary artery disease (CAD) as well as the severity of coronary lesions with echocardiography,Methods According to the results of coronary angiography,80 patients underwent coronary angiography were divided into coronary heart disease group (CHD group,4 6 cases) and without coronary heart disease group (control group,34cases),and according to coronary artorrythe severity,CHD goup was divided into subgroups of single-vessel disease (24 cases) and multivessel disease subgroup(22 cases).Tho epioardial fat thickness on the free wall of the right ventricle was measured at end-systole from the para-sterna,long-axis vlews.The relationship between EAT and the risk factors of CAD (such as age,gender,hypercholesterolemia,hypertenston,diabetes,smoking,family CAD history) as well as the severity of coronary lesions were analyzed.Results EAT in multivessel disease CAD group [(8.85 ± 1.44)mm] was significantly higher than that in single vessel CAD group[(6.86 ± 1.09) mm] and control group [(4.58 ± 1.12) mm] (all P ＜ 0.01).EAT was significantly related with the risk factors of CAD.Although the risk factors of CAD such as age,blood glucose,blood pressure were adjusted,EAT was still independently associated with CAD (OR:5.394,95 ％ CI:1.700 ～ 17.1 12,P =0.004).Concluslon The level of EAT is significantly correlated with CAD and the severity of coronary lesions.

Objective To study the effect of and its mechanism Bushen Qiangdu Formula (Formula for reinforcing kidney and strengthening spine) on patients with osteoporosis induced by ankylosing spondylitis (AS).Methods All 50 AS patients with osteoporosis were treated with Bushen Qiangdu Formula for six months.Before and after treatment,the observation term includes serum osteoprotegerin (OPG),bone mineral density (BMD),serum boneglaprotein (BGP),calcitonin (H-CT),parathyroid hormone (PTH),bone-specific alkaline phosphatase (BAP),collagen I carboxyl-terminal-prolonging peptides (CICP),urine deoxidation pydidinoline (DPD),C-telopeptide of type I collagen (CTX-I),erythrocyte sedimentation rate (ESR),C reactive protein (CRP),Bath AS Function Index (BASFI),Bath AS dynamic Index (BASDI),and symptoms and signs.Results After treatment,the serum OPG significantly increased (P

Objective To investigate the correlation of social capital and professional burnout in nursing staff. Methods Totally 1329nursing staff were recruited from 6 hospitals in China. They were investigated with the social capital scale and nursing personnel professional burnout scale. Results The mean score of social capital was 13.37±1.30;the mean score of 3 Scales of professional burnout was 24.39± 9.98, 6.24 ± 4.78, 23.37 ± 10.12. The 4 Scales scores of social capital were negative correlated with emotional exhaustion scale, the lack of human individual scale(r=-0.564 to-0.211,P<0.05). Besides with trust and security dimension, low sense of achievement were positively correlated with the total score of social capital (r=0.281-0.281, P<0.05). Conclusion Social capital of nursing staff have important effects on nurse's professional burnout. Nursing managers should take effective measures to reduce nurse's professional burnout.

Objective To establish content determination of hydroxyl safflower yellow A in Biyangqing.Methods Hhgh-performance liquid chromatography(HPLC)was used in the determination.A C18 column was used for the separation flow rate Was set at 1.0mL/min,the temperature of the column was set at 30℃,and wavelength of diction was set at 403 nm.with 100.08%average recovery and 0.98%RSD.Conclusion This detrmination method is specific and reproducible and can be used to control the quality of Biyangqing.

An indirect square polarographic method was established f or the determination of ascorbic acid in pharmaceuticals using the oxidation-re duction action between Cu2＋ and ascorbic acid. There was a reduction wav e of Cu2＋ at about －0．24　V in buffer solution of NH3-NH4 Cl. The quantities of ascorbic acid is determination according to the decrement of peak heights when ascorbic acid was added. The linear range for ascrobic acid was 2.0×10－6～3．0×10－4 mol/L. Ascorbic acid in Vitami n C tablets was determined, the relative standard deviation is 2.9%.

BACKGROUND:Stem cel transplantation has a certain effect in the treatment pulmonary arterial hypertension.
OBJECTIVE:To investigate the effect of bone marrow mesenchymal stem cel s transplantation on the treatment of pulmonary arterial hypertension and to discuss the mechanism.
METHODS:Bone marrow mesenchymal stem cel s were in vitro cultured, purified and amplified by density gradient centrifugation method, and labeled with the fluorescent dye for preparation. Pulmonary arterial hypertension model was established by subcutaneous injection of monocrotaline. One week after modeling, the rats were randomly divided into three groups. Rats in the stem cel transplantation group and pulmonary arterial hypertension group received subcutaneous injection of monocrotaline to establish the pulmonary arterial hypertension model. One week later, the rats in the stem cel transplantation group received sublingual vein injection of bone marrow mesenchymal stem cel solution, the rats in the pulmonary arterial hypertension group were injected with the culture medium without stem cel s, and the rats in the control group were injected with the normal saline in the same dose.
RESULTS AND CONCLUSION:At 2 weeks after transplantation, compared with the mesenchymal-induced pulmonary arterial hypertension rats, the hemodynamic parameters and the ratio of right ventricular/body weight of the rats in the stem cel transplantation group were significantly improved (P<0.05);the degree of pulmonary vascular remodeling was significantly reduced (P<0.05). Fluorescence microscope observation showed that the transplanted bone marrow mesenchymal stem cel s could alive at least 2 weeks in the stem cel transplantation group, and part of the stem cel s could differentiate into pulmonary vascular endothelial cel s. The results show that bone marrow mesenchymal stem cel transplantation can significantly improve the pulmonary vascular and right ventricular structural impairments in the rats with mesenchymal-induced pulmonary arterial hypertension.
