Chronic lung disease is a very common complication caused by inhaled hyperoxia, mechanical ventilation and pulmonary infection in preterm infants. It shows early inflammation and late alveoli fusion with mesenchymal fibroblast proliferation. Mitogen activated protein kinase is a very important signal transduction pathway in eukaryotic cells.It plays an important role in the cell inflammation, proliferation, differentiation, survival and apoptosis, which may contributes to the chronic lung disease.

Objectives:To investigate the prevalence situation and antibiotic resistance of chlamydia trachomatis (CT),ureaplasma urealyticum(UU) and mycoplasma hominis(MH) in infertile female patient,and to analyze the resistant of mycoplasma to common antibiotics. Methods:The cervical secretion samples from 2186 female infertility and 210 pregnancies women were collected. Then chlamydia trachomatis antigen was detected by immunoassay. Mycoplasma (UU and MH) were isolated and tested antimicrobial susceptibility for 12 kinds of antimicrobial drugs. Results:In the trial group 173 were CT-positive at a rate of 7.9%,and 1102 were positive for the mycoplasmae at a rate of 50.4%,of which 987 were UU infections and 115 were MH infections.The number of CT,UU and MH infections totaled 1275 cases,leading to an overall infection rate of 58.3%. The top three antibiotics for drug sensitivity in the UU,MH and UU+MH cultures were josamycin,minocycline and clarithromycin.The three antibiotics,to which the pathogens were most tolerant,included ofloxacin,norofloxacin and sparfloxacin. Conclusion:The infection rate of chlamydia and mycoplasma in infertility women is obviously higher than normal pregnanted,this shows the fact that chlamydia and mycoplasma infection of genitourinary tract may be one reason of infertility.The sensitivity of mycoplasma to common antibiotics especially to quinolones and macrolides has decreased.

AIM To explore whether or not the function of insulin like growth factor (IGF I) in promoting osteopontin gene expression and protein synthesis of rat vascular smooth muscle cell (VSMC). METHODS Cultured cells were incubated with different concentration of IGF I for different hours, then RT PCR and Western blotting analysis were used to observed the effects of IGF I on osteopontin expression of rat vascular smooth muscle cells RESULTS IGF I (20 ?g?L -1 ) could obviously induce the gene expression and protein synthesis of osteopontin, RT PCR results showed that the ratio of mRNA of osteopontin and ? actin in cells incubated with IGF I (20 ?g?L -1 ) for 3, 24 and 48 h increased by 39 70%,40 44% and 54 05% respectively, as compared with that of the control ( P

It was pointed out that the development of theory of TCM was restricted by the indistinct concepts.The advantages and disadvantages of the concept between traditional Chinese medicine and western medicine were analyzed.Basing on literature researches and modern science researches can solve the concept problems of the theory of TCM.

This paper,introduced the manufacture process and quality control method of Xiao- erqingfei Suppository.The suppository tallied with requirements of China Pharmacopeia (the 85th edition).Its main active components were identified with TLC.Two represen- tative components were determined:ephedrine and glycyrrhizic acid.

Objective:To explore the multiple meditation effects of emotional intelligence and self-esteem between interpersonal initiative personality and social positive adaption in left-behind junior high school students.Methods:Totally 331 left-behind junior high school students [165 boys,160 girls,average age of (14.5 ± 1.2) years] were selected.They were assessed with the Interpersonal Self-Support Scale for Middle School Students (ISSS-MSS),Emotional Intelligence Questionnaire (EIQ),Rosenberg Self-Esteem Scale (RSES) and Social Adjustment Scale (SAS-YB).Results:The scores of social positive adaption were positively correlated with the scores of interpersonal initiative personality,EIQ and RSES (r ＝ 0.47-0.67,Ps ＜ 0.001).Path analysis showed that interpersonal initiative personality had direct effects on social positive adaption (β ＝ 0.47,P ＜0.001).Mediation modeling showed that interpersonal initiative personality could exert effects on social positive adaption indirectly through the mediating effect of not only emotional intelligence,but also self-esteem (x2/df＝ 3.03,TLI ＝ 0.87,CFI ＝ 0.89,RMSEA ＝ 0.08).Conclusion:The present study indicates that parallel multiple mediation model of emotional intelligence and self-esteem could explain the mechanism of influence of interpersonal initiative personality on social positive adaption appropriately.

Objective To evaluate MRI diagnostic accuracy and clinical value on the pancreatic carcinoma.Methods 79 patients with suspected pancreatic carcinoma were imaged by T1-weighted spin-echo pulse sequences and T2-weighted fast spin-echo pulse sequences in axial,sagittal and coronal planes with a pelvic phased-array coils.Results 43 patients were diagnosed as pancreatic carcinoma using MR imaging,in which 39 patients were proved pathologically by biopsy.Conclusion MRI is effective diagnostic modality in localizing and staging pancreatic carcinoma and guiding for the choice of pancreatic carcinoma treatment.

Objective To investigate the effect of anti-snoring pillow for the treatment of obstructive sleep apnea in patients with heart failure.Methods Forty seven HF patients with OSAHS and 12 HF patients with simple snoring were enrolled.All the patients were divided into 3 groups:control group (n =12),mild-moderate OSAHS group (n =26) and severe OSAHS group (n =21).All the patients received the treatment of anti-snoring pillow and their sleep apnea parameters were evaluated by PSG at the same time.Results The sleep apnea parameters including AHI,OAI,ODI,mean SpO2％ and snore index were significantly improved in severe and mild moderate OSAHS group with anti-snoring pillow.Conclusion Anti-snoring pillow can reduce snoring index in all OSAHS patients and simple snorers.Sleep apnea and hypoxemia were greatly improved in mild-moderate OSAHS-HF patient while the anti-snoring pillow is not perfect in severe OSAHS patients with HF to replace PAP.

Methylenetetrahydrofolate reductase(MTHFR),a key enzyme in methionine-folic acid metabolism,participates in the synthesis of thymidine monophosphate(TMP) and purine as an indirect donator of methylium.It plays an important role in maintaining the normal level of homocysteine and DNA repair and replication.The MTHFR gene mutation decreases the activity of enzymes,increases the homocysteine level of blood plasma,and induces abnormal DNA methylation and various diseases.This review focuses on the structure and function of the MTHFR gene,its polymorphism and the relationship between its polymorphism and congenital heart disease.
