As China’s economy has entered the development stage of a 'new normal,' the traditional path relying on investment scale expansion for economic growth can no longer sustain. Thus the key of the supply-side structural reform lies in breaking through the long-term path dependence and facilitating the transformation and innovation of socio-economic and urban development. This paper takes Shenzhen as the benchmark of the comparative study, and Guangzhou and Tianjin as the comparative object to analyze the contributions of the demand-side 'troika' – investment, consumption, and export, to economic growth from 1986 to 2015. Then, it introduces multiple growth elements on the supply-side to analyze the significant contribution elements in urban economic growth and their contribution degrees. Meanwhile, in combination with the economic development background and the policy guidance since the reform and opening up, the paper analyzes the characteristics of the development paths and their trends of the three cities. In the end, based on the comparative study, it carries out a discussion on the development path for mega-cities and their urban planning strategies at the new era from three perspectives.

The copolymerization of DL-LA and 3-BMG was carried out in bulk with stannous 2-ethythexanoate as the catalyst. A series of copolymers with pendant protected groups were obtained and characterized by H-1-NMR and GPC analysis. The monomer reactivity ratios were evaluated by the Fineman-Ross method and the Kelen-Tudos method and found to be r(BMG)=1.96 and r(LA)=0.37, respectively.

Late-onset hypogonadism （LOH） has been described as a clinical syndrome comprising symptoms consistent with androgen deficiency and a circulating concentration of testosterone in the low-to-normal range in some middle-aged and elderly men. The presence of symptoms may affect the health and quality of life in aging men and it has become a hot spot in global medical research, diagnosis, and treatment in the recent years.

To investigate the expression of the subunit p65 of NF-κB and inhibitor kappa B alpha (IκBα) in mouse uterus during peri-implantation, thereby investigating whether transient activation of nuclear factor-κB (NF-κB) takes place during embryo implantation in mice. Immunohistochemical technique was used to examine the expression and localization of p65 in endometrium or deciduas, and Western blot analysis was employed to detect the levels of IκBα protein in mouse endometrium or deciduas. P65 protein was detected in stromal cells, epithelial cells of endometrium as well as in myometrium. Staining was predominately seen in the cytoplasm of the cells. Staining intensity for p65 was stronger in the epithelial compartment than the stromal compartment and myometrium. Staining intensity increased slightly during pregnancy, and it reached a high level on pregnancy day 5 and day 8. In contrast to p65, the level of IκBα protein was lowest on pregnancy day 5 in all groups. Our results suggested that NF-κB may regulate embryo implantation by its transient activation in mice.

BACKGROUND: Micro RNAs are small non-coding RNAs of approximately 22 nucleotides in length, and play important regulatory roles in normal heart development and the pathogenesis of heart diseases. Recently, a few prospective studies have implicated the diagnostic role of micro RNAs in congenital heart defects(CHD).DATA RESOURCES: This review retrieved the research articles in Pub Med focusing on the altered microR NAs in cardiac tissue or serum of patients with CHD versus healthy normal controls, as well as the studies exploring circulating microR NAs as potential biomarkers for(fetal) ***: Most of the studies of interest were conducted in recent years, implicating that the topic in this review is a newly emerging field and is drawing much attention. Moreover, a number of differentially expressed microR NAs between CHD specimens and normal controls have been ***: Circulating micro RNAs may serve as potential biomarkers for diagnosis of CHD in the future, with more efforts paving the road to the aim.

The rural land institutions have confined the process of China's urbanization for a long time. During the 13 th Five-Year Plan period, the Chinese government will push forward a new round of rural land institutional reform, so as to promote the restructuring of current rural land use pattern, change related elements concerning urbanization, and realize the transformation of the urbanization mode. Taking Jiangsu Province, a comprehensive pilot site of new urbanization at the provincial level in China, as an example, the paper summarizes the practical experience of rural land institutional reform in Jiangsu during recent years. Further, through analyzing the influence of rural land institutional reform on the urbanization process of Jiangsu Province during the 13 th Five-Year Plan period, the paper puts forward some policy measures, with the hope of providing a lasting impetus for the new urbanization in Jiangsu Province as well as a reference for other provinces in China.

Expression of endogenous ouabain in placenta and the concentrations of serum ET-1 and NO were examined in 30 patients with hypertensive disorder complicating pregnancy （HDCP） and 30 healthy pregnant women to investigate the effect of endogenous ouabain on HDCP. Compared with the healthy pregnant group, the expression of endogenous ouabain dramatically increased in the HDCP groups （P〈0.01）. There was a significantly positive correlation between the expression of en- dogenous ouabain with ET-1 （r= 0.5567, P〈0.01）, while the correlation of endogenous ouabain and NO was significantly negative （r=-0.6895, P〈0.01）. As expected, the correlation between ET-1 and NO was negative （r=-0.7796, P〈0.01）. ET-1 concentrations of maternal and cord sera in HDCP groups were significantly higher in comparison with healthy pregnant group （P〈0.01）. On the contrast, NO concentrations were much lower in the maternal and cord sera of HDCP groups as compared with healthy pregnant group （P〈0.01）. Our data suggest that endogenous ouabain is directly involved in the nosogenesis of HDCP, with accompanying decreased NO and the elevated of ET-1.

A growing number of researches have shown that ouabain can regulate mammalian sperm function and male reproduction by modulating the sperm motility, capacitation and acrosome reaction in vitro. This study further examined the relationship between ouabain and asthenozoospermia. In this study, the rat was intraperitoneally injected with ouabain at different concentrations（low-dose ouabain group： 12.5 μg/kg body weight per day, and high-dose ouabain group： 25 μg/kg body weight per day） for 30 days to establish the asthenozoospermia model. The sperms from 60 males with normal fertility were incubated with ouabain of gradient concentrations（10-7–10-2mol/L） for 4 h. The sperm motility was evaluated under a microscope. Moreover, the endogenous ouabain（EO） level was determined in seminal plasma of mild or severe asthenozoospermia patients and males with normal fertility by competitive inhibition ELISA. The results showed that the sperm motility was significantly diminished in the rats treated with different concentrations of ouabain. The number of motile sperms（grades a and b） was decreased greatly in a time- and dose-dependent manner in 10-5–10-2mol/L ouabain groups（P0.01）, while no obvious change in sperm motility was observed in 10-7–10-6mol/L groups even for 4-h incubation（P0.05）. Furthermore, the EO level was significantly increased in asthenozoospermia patients as compared with that in males with normal fertility（25.27±1.71 μg/L in mild asthenozoospermia patients, 26.52±1.82 μg/L in severe asthenozoospermia patients, 19.31±1.45 μg/L in normal fertility men）（P0.01）. In conclusion, rat asthenozoospermia was successfully established by intraperitoneal injection of ouabain, and 10-5mol/L ouabain was sufficient enough to inhibit sperm motility in vitro. Moreover, EO, a normal constituent of seminal plasma, was highly expressed in asthenozoospermia males as compared with normal fertility ones.
