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.

Congenital heart disease often lost the opportunity of radical sureryfor secondary pulmonary hypertension.pulmonary hypertension is pathologicallycharacterizzed by pulmonary vascular remodeling,including the vascular smooth musclecell' s proliferation,migration and extracelluar matrix deposition,Recently,someresearchers have found that connective tissue growth factor can bind with somesurface receptors of vascular smooth muscle cells,causing some biological behaviorchanges such as proliferation,migration and extracellular matrix abnormaldeposition,and activating crresponding gene expression through this signaltransduction pathway.Pulmonary vascular remodeling may be one of the molecularpathogenesis in pulmonary hypertension.

Objective To explore the application value of color Doppler ultrasound in screening of fetal con-genital heart disease and its significance.Methods 4 132 cases of the expectant mothers were selected,using color Doppler ultrasonography on the line screening of five section to detect fetal cardiac,to compare with the actual clinical situation and analyze the occurrence of fetal congenital heart disease.Results Among 50 cases(1.21%) of congeni-tal heart disease,28 cases were live births, accounted for 56.00%,13 cases of induced abortion, accounted for 26.00%,9 cases died,accounted for 18.00%.48 cases were detected by ultrasound,relevance ratio was 1.16%,the accuracy rate was 96.00%,the missed diagnosis rate was 4.00%.28 cases of live births undergoing surgical correc-tion,treatment effect was good,48 cases were detected,including 10 cases of ventricular septal defect,6 cases of tetral-ogy of Fallot,6 cases of atrial septal defect,5 cases of endocardial cushion defect,4 cases of single chamber,4 cases of persistent truncus arteriosus,3 cases right ventricular dysplasia,3 cases of tricuspid valve shift malformation,2 cases of persistent left superior vena cava,2 cases left ventricular dysplasia,2 cases of aortic arch interruption,1 case of rhabdomyoma.Conclusion Using color Doppler ultrasound detection for pregnant women can effectively detect severe congenital heart disease in the fetus,stop gravid timely,which can effectively improve the level of prenatal and postnatal care that is worth clinical application.

Rational use of antibiotics can delay the emergence of antimicrobial resistance, and antimicrobial resistance surveillance provides the basis for standardizing clinical rational use of antibiotics. Therefore, antimicrobial resistance surveillance network is of great importance, and its construction can improve the rational use of antibiotics.The construction of antimicrobial resistance surveillance network should emphasize the capacity building of clinical microbiology laboratory and enhance quality control of resistance data based on the standards put forth by Clinical and Laboratory Standards Institute ( CLSI) .

The International Society on Thrombosis and Haemostasis has proposed to hold World Thrombosis Day on October 13 annually from 2014 to improve awareness and education of thrombosis. Thrombotic diseases are multidisciplinary disorders involving multiple systems.Thus, multidisciplinary team treatment for thrombotic diseases should be developed in China.A comprehensive study of genetic factors for thrombotic diseases is expected to achieve early diagnosis and risk prediction for this type of disease, and thus precision diagnosis and individualized treatment can be achieved.

Severe burn is often accompanied by multiple organ damage. Acute lung injury (ALI) is one of the most common complications, and often occurs in the early stage of severe burns. If it is not treated in time, it will progress to acute respiratory distress syndrome (ARDS), which will be a serious threat to the lives of patients. At present, the treatment of ALI in patients with severe burn is still remained in some common ways, such as the liquid resuscitation, the primary wound treatment, ventilation support, and anti-infection. In recently, human umbilical cord mesenchymal stem cells (hUCMSCs) have been found having some good effects on ALI caused by various causes, but few reports on the efficacy of ALI caused by severe burns were reported. By reviewing the mechanism of stem cell therapy for ALI, therapeutic potential of hUCMSCs in the treatment of severe burns with ALI and a new approach for clinical treatment was provided.
