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.

This study was to evaluate the risk factors of nocturnal hypoglycemia in elderly patients with type 2 diabetes by continuous glucose monitoring system. Fifty-one type 2 diabetic patients aged 60 or above were enrolled and the episodes of nocturnal hypoglycemia were documented. The risk factors of nocturnal hypoglycemia were analyzed by logistic regression and the cut-off of glucose levels at bedtime for nocturnal hypoglycemia was evaluated. There were twenty-two patients with total 681 nocturnal hypoglycemic episodes. Logistic regression analysis showed that the lowest glucose level at bedtime was the risk factor of nocturnal hypoglycemia (OR=0.36, 95% CI:0.13-1.00, P<0.05), while the gender, age, diabetes duration, therapy regimen, the highest and average glucose levels at bedtime were not associated to nocturnal hypoglycemia. Receiver operating characteristic curve (ROC) showed that the bedtime glucose at≤6.2 mmol/L was the best cut-off point for predicting nocturnal hypoglycemia.

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.

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.

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.

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

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) .
