As is well known, MicroRNA is one of the keys of regulating cell differentiation and metabolism, even body growth and development.In these few years, great progresses of MicroRNA have been made in lung development and the progressive mechanism of lung disease as well as the diagnosis and treat of lung disease such as lung cancer and chronic obstructive pulmonary disease.This review summarizes the latest progresses in the domain of MicroRNA about lung disease.

In recent years, many studies have claimed that the intrauterine infection is one of the most common causes of cerebral palsy. Cerebral palsy is associated with the brain injury directly or indirectly. With the direct mechanisms including breakdown of infected nerve cells of the mouse by intrauterine infection,hydrocephalus, dilation of the cerebral ventricles and ependymitis being illuminated uninterruptedly, researches of the indirect mechanism in cerebral palsy caused by intrauterine infection become the hot issue in the domain.Besides the inflammation mediators theory and down-regulated expression of development of the nervous system related factors, there were still several important elements which can cause brain damage such as placental excretive hormone imbalance, change of activity of Notch signaling and gene mutation/deletion and so on.Mechanisms and the interaction between them built up network effect.

To study the dynamic relationship of total health expenditure and economic growth so as to provide references for designing health economic policies. Methods: Using the regression models with multiple structural changes to estimate the structural change point of model parameter. Results: Compared to the elastic coefficient of economic growth, the total health expenditure and social health expenditure remained stably, the elasticity coefficient of government spending on health increased after decreased while elastic coefficient of personal spending health costs decreased after increased. Conclusion:In the early years of 1990s, the responsibility of government in health care financing funding weakened, which led to the increasing personal expenses. The situation began to reverse since 2004.

Objective To investigate leukotriene B4 secretion from DC and expression of its receptor,BLT(LTB1,LTB2).Methods Bone marrow(BM)-derived DC from healthy Balb/c mice were incubated with rmGS-CSF and rmIL-4,and then stimulated with LPS.Light microscopy and flow cytometry were used to identify DC,ELISA and RT-PCR methods were used to detect LTB4 secretion in culture supernatant and mRNA expression of BLT(BLT1,BLT2) in immaturation and mature DC,respectively.Results LTB4 concentration was(10.667?(2.394)ng/L)、(7.089?(1.810) ng/L)、(3.222?(0.995)ng/L) and(14.217?(3.396)ng/L) in 2,4 and(6 d)(immaturation) and(8 d) (maturation) respectively.LTB4 level decreased progressively during DC differentiation.LTB4 level in mature DC was higher than that in immature DC(P

Objective:To investigate the expression of E2F3 mRNA in bladder urothelial carcinoma and normal bladder urothelial tussue to explore its relationship with the genesis and progression of bladder urothelial carcinoma.Methods:The expression of E2F3 mRNA in 34 cases of bladder urothelial carcinoma and 19 cases of normal bladder urothelial tussue was examined by RT-PCR.Result:The positivity rates of E2F3 mRNA in bladder urothelial carcinomas and normal bladder urothelial tussues were 47.1%(16/34) and 0%(0/19) respectively.The expression level of E2F3 mRNA in bladder urothelial carcinomas was significantly higher than that in normal bladder urothelial tussues(P

Objective:To investigate the relationship between TGF-?1 and the contents of IL-6 and IL-8 in peripheral blood after the penetrating keratoplasty in rat.Methods:Rat model of penetrating keratoplasty was established.ELISA assay was used to detect the contents of IL-6 and IL-8 in the peripheral blood at the first week,second week,third week,and fourth week postoperatively.Results:Compare with the control groups and self groups,the expression level of IL-6 and IL-8 in all experimental groups markedly decreased at different periods postoperatively(P

[Objective]Combing the application of ginseng in the past physicians to make readers understand the efficacy of ginseng,and to be flexible in order to better serve human health.[Methods]Through consulting the ancient books of materia medica,the understanding of the ancient physicians and the application of hanren formulae were summarized and analyzed.[Results]Although the ancient physicians of the past believed that ginseng was subject to tonify five organs,quiet spirt,set soul,stop fright,remove pathogen,in addition to bright eye,happy,educational. long taking makes people fit and live longer,but with the development of the times,the Han dynasty in to nifying Qi torelieve thirst,tonify Qi for deficiency,the Tang dynasty in tonifying heart Qi,benefiting heart spirit,the Song dynasty in complement,benefiting Qi,the Ming dynasty in benefiting qi,Qing dynasty in tonifying Qi and Yin,modern in emergency first aid application.[Conclusion]Through the analysis of the application of ginseng in past dynasties,the complement ginseng can be more widely used in clinic,and better serve human health.

Stenosis or occlusion of vertebral artery origin is one of important reasons of posterior circulation ischemia. Vertebral artery stenting can reduce posterior circulation ischemia in patients with vertebral artery origin stenosis. Restenosis after stenting is an important reason influencing the long-term efficacy.This article reviews treatment approaches of vertebral artery origin stenosis, restenosis after stenting and the related factors.

ObjectiveTo study whether the current Institute of Medicine (IOM) pregnancy weight gain recommendationsvarybypre-pregnancybodymassindex(BMI)wassuitabletoChinese people.MethodsA study was conducted on 4736 term singleton live birth gravidas,who were diagnosed normal glucose metabolism and delivered in Peking University First Hospital in 2005 and 2009,by reviewing the medical records.Based on the pre-pregnant BMI,the selected cases were divided into 3 groups:low body mass group ( BMI ＜ 18.5 kg/m2,n =465 ),normal body mass group ( BMI 18.5 - 24.9 kg/m2,n =3549),over body mass group ( BMI ≥ 25 kg/m2,n =722).All the cases were divided into 3 subgroups based on pregnancy weight gain as below,within,and above the IOM recommendations in each pre-pregnant BMI group.Totally 4736 newborns were divided by birth weight into 3 groups:normal birth weight group ( weight 2500 - 4000 g,n =4339 ),macrosomia group ( weight ≥ 4000 g,n =359 ) and low birth weight group (weight ＜ 2500 g,n =38).The difference of age,gestational age,pre-pregnant weight,pre-pregnant BMI and history of delivery of cases between 2005 and 2009 were analyzed.The difference of pregnancy outcome of women whose gestational weight gain was below,within,and above the IOM recommendations was analyzed.Results (1) Compared to mothers with pregnancy weight gain within IOM recommendations in low body mass group,risk of low birth weight in offspring was elevated tendency with pregnancy weight gain below IOM recommendations ( OR =3.71,95％ CI:0.97 - 14.12,P =0.055 ).(2) In normal body mass group, compared to women with pregnancy weight gain within IOM recommendations, risk of macrosomia in offspring was elevated with pregnancy weight gain above IOM recommendations ( OR =2.14,95％ CI:1.62 - 2.83,P ＜ 0.01 ).( 3 ) In over body mass group,compared to women with pregnancy weight gain within IOM recommendations,risk of macrosomia in offspring was elevated ( OR =3.25,95％ CI:1.65 -6.39,P =0.001 ) and risk of hypertensive disorders complicating pregnancy was high ( OR =1.79,95％ CI:1.04 -3.09,P =0.037 ) in women with pregnancy weight gain above IOM recommendations.ConclusionThe current IOM pregnancy weight gain recommendations vary by pre-pregnancy BMI may be suitable to Chinese people.
