Objective To study the characteristics of plasma adiponectin levels exhibiting in gestation women and newborns, as well as the relationships between adiponectin levels and fetal birth weight. Methods Totally 98 subjects have been considered in this study, in-cluding venous blood samples of 36 healthy non-pregnant women (control group), 31 uncomplicated pregnant women (pregnancies group) and the cord blood samples taken at delivery of their singleton infants born at term (newborns group). The concentrations of adiponectin and insulin were determined by radioimmunoassay technique. And SPSS was used for statistical analyses. Results The adiponectin level in women of late period of gestation (WLPG) (11.10±5.72)g/ml was lower than that of other two groups, and the newborns average cord plasma level of adiponectin was (30.71±12.77) g/ml significantly higher than that of the control group (16.52±6.87) g/ml. The adipone-ctin level for WLPG was correlated with FINS and HOMA-IR (r = -0.411, -0.393, P <0.05). The adiponectin level in cord plasma was positively correlated with birth weight(r = 0.416, P < 0.05). The adiponectin level in WLPG was correlated neither with the adiponec-tin level nor body weights of their newborns. Conclusions The average cord plasma adiponectin level of newboms is significantly higher than that of the control group and WLPG. It is positively correlated with birth weight, which suggests that adiponectin may be involved in reg-ulating fetal growth. The adiponectin level in WLPG is correlated neither with the adiponectin level nor body weights of their newborns.

The purpose of this study was to reveal the current situation of health technology transfer in Shanghai hospitals,and to analyze the problems and needs.Questionnaire and interview were adopted for the study.We found that in the past 3 years,the transformation rate of patent technologies at Shanghai Tertiary Hospitals was 5.88％.The transfer routes mainly involves proactive enlist of enterprises by project leader,technology brokerage,exhibitions of patents achievements,friends' recommendation,etc..The main factors impacted the transfer included poorer quality of patent,lacking efficient management,and lacking channels for transfer.In order to improve the transfer of patents,hospitals need to provide information service,technology assessment,project packaging,patents application,consultant,and relevant trainings etc.Other things that could promote health technology transfer are to improve scientific research system,to enhance the quality of scientific achievements,and to develop technology brokerage.

Objective To investigate the correlation of XRCC1 Arg194Trp Arg399Gln Single nucleotide polymor-phism (SNP) with radiotherapy response of squamous cell carcinoma of cervix. Methods Patients with exogenous type cer-vical squamous cell carcinoma confirmed by histopathology were selected for our study. These include:patients in stageⅠ(4 cases), patients in stageⅡ(36 cases), patients in stageⅢ(30 cases), patients in stageⅣ (3 cases). There are 30 patients with tumor diameter less than 4 cm and 43 patients with tumor diameter over 4 cm in our test. There are 36 cases with dose point A less than 80 Gy and 37 cases with dose point A over 80 Gy . Radiotherapy outcomes showed 47 cases of complete re-mission and 26 cases of part remission. Polymorphisms Arg194Trp, Arg399Gln of XRCC1 gene in 73 cervical cancer pa-tients were analyzed by mismatch amplification polymerase chain reaction (MAMA-PCR). Results Arg/Arg, Arg/Trp, TrP/Trp of Arg194Trp genotype distribution were 31 (42.5%), 37 (50.7%), 5 (6.8%) respectively. Arg/Arg, Arg/Gln, Gln/Gln of Arg399Gln distribution were 6 (35.6%), 39 (53.4%), 8 (11.0%) respectively. The response to radiotherapy was not statistical-ly significant in three genotypes, Arg/Arg, Arg/Trp, TrP/Trp of XRCC1 at codon 194(P>0.05). Neither was XRCC1 at codon 399. Multivariate analysis showed that late clinical stage was a risk factor of part remission. Conclusion SNP of XRCC1 gene at codon 194 and codon 399 could not predict clinical response of patients with squamous cell carcinoma of cervix to ra-diotherapy. The patients with advanced cervical cancer had poor response to radiotherapy.

Objective To investigate the effects of environmental enrichment (EE) on the neurological functions in patients with stroke. Methods From May, 2013 to November, 2015, 76 patients with stroke were selected and randomly divided into control group (n=39) and EE group (n=37). Both groups received routine therapy and the EE group received EE in addition. They were assessed with simplified Fugl-Meyer Assessment (FMA), Montreal Cognitive Assessment (MoCA) and modified Barthel Index (MBI) before and after treatment. Re-sults The scores of FMA, MoCA and MBI increased in both groups after treatment (t>2.339, P<0.05), and the scores of MoCA and MBI in-creased more in the EE group than in the control group (t>2.187, P<0.05). Conclusion EE could promote the recovery of cognitive function and activities of daily living in patients with stroke.

Objective To investigate the effects of pioglitazone on osteoblast proliferation and apoptosis.Methods MC3T3-E1 mouse osteoblastic cells were treated with 0, 5, 10, 20, 30, and 40 μmol/L pioglitazone for 24 h. Cell viability was measured by MTT, cell cycle and apoptosis were inspected with flow cytometry, the expressions of Bcl-2 and Bax proteins were examined via immuno-chemical staining. Results Survival of osteoblasts decreased in a dose-dependent manner. Compared with the control group, the cells in the G0/G1 and G2/M stages increased, while the cells in S stage decreased significantly. The percentage of apoptosis at 5 and 10 μmol/L were lower than that of the control group(P ＜ 0.05), While it was increased significantly at 30 and 40 μmol/L(P ＜0.01). Bax expression was attenuated at 10 μmol/L(P＜0. 01), returned to normal by 20 μmol/L, and was increased by 30 and 40 μmol/L(P ＜ 0. 01). Bcl-2 expression was enhanced at the dose ≤ 20 μmol/L(P ＜0.01). Positive correlation was found between the death rate and the expression intensity of Bax/Bcl-2(n = 15, r=0.796, P＜0.01). Conclusions Pioglitazone inhibits apoptosis of osteoblasts at low concentrations and protects the cells, but promotes their apoptosis at higher concentration, Bax/Bcl-2 may play an important role in mediating the piglitazone-induced apoptosis of osteoblasts. It inhibits DNA synthesis and cell proliferation.
