Objective: To investigate the quality of life and its influencing factors among patients with gestational diabetes mellitus (GDM), so as to provide insights into the improvements in the quality of life among patients with GDM. Methods: GDM patients admitted to Department of Obstetrics and Gynecology, Hangzhou First People's Hospital Affiliated to Zhejiang University Medical School from June 2021 to June 2022 were recruited. Participants' demographics, diagnosis and treatment, sleep quality, depression and social support level were collected. Patients' quality of life was evaluated using the Quality of Life Scale for Pregnant Women with Gestational Diabetes Mellitus, and the factors affecting the quality of life were identified among patients with GDM using a multivariable linear regression model. Results: A total of 300 questionnaires were allocated, and 284 valid questionnaires were recovered, with an effective recovery rate of 94.67%. The respondents had a mean age of (32.81±4.93) years, and the mean scores for the quality of life was (92.63±14.10) points. Multivariable linear regression analysis identified depression (β'=-0.293), sleep disorder (β'=-0.177), insulin therapy (β'=-0.316), regular exercise (β'=0.272) and social support level (medium: β'=0.153; high: β'=0.381) as factor affecting the quality of life among GDM patients. Conclusions GDM patients have a low quality of life. Depression, sleep disorders, insulin therapy, and lack of exercises may cause a decline in the quality of life among GDM patients, and strong social support facilitates the improvements in the quality of life among GDM patients.

Objective This study was designed to determine the in vitro sensitivity of LMWH caused by different reagents,and to explore whether the ACT can be used to monitor LMWH.Methods This study was performed in vitro.ACT was measured with different reagents(glass beads,celite,and kaolin)on volunteer(n =30)blood samples spiked with increasing concentrations of LMWH(datleparin,0.2-1.8IU/ml).Linear regression analysis was performed to establish a regression equation from different concentration of datleparin and corresponding ACT values.Results Analysis of dose-response curves obtained in vitro,an excellent linear relationship was observed between the ACT and dalteparin concentrations for all three reagents(p less than 0.01).Differences in slope of the regression curves of ACT were observed with all the reagents tested(glass beads 249.7s/IU,celite 77.7s/IU,and kaolin 59.3s/IU,p less than 0.01).Reagents vary widely in their in-vitro sensitivity related to dalteparin.In the concentration range of 0.2-1.8 IU/ml,the gaolin reagent was insensitive to dalteparin,and glass beads was the most suitable reagent for monitoring the anticoagulant effect of dalteparin.Conclusions Glass beads,celite,and kaolin.Glass beads were the most suitable reagent for monitoring the anticoagulant effect of dalteparin.Vary widely in their in-vitro sensitivity related to datleparin.

Objective To evaluate the clinical efficacy of transpedicular intracorporeal bone graft with allogenic bone in treatment of thoracolumbar osteoporotic compression fracture. Methods A total of 45 patients with thoracolumbar osteoporotic compression fractures were treated with posterior short segment pedicle screw fixation and transpedicular intracorporeal bone graft with allogenic bone. Anteroposte-rior and lateral X-ray photographs were taken before and after operation and at follow up period to determine the ratio of anterior and middle compressed body height to the normal height, the vertebral angle and the superior-inferior endplate angle. The extent of local pain was measured by VAS score. The implant failure was also recorded during follow-up. Results The operative reduction and interbody bone grafting exerted a satisfactory effect on the ratio of anterior and middle body height to the normal height, the vertebral angle and the superior-inferior endplate angle. Local back pain disappeared immediately after surgery in 34 patients out of 38 patients followed up for more than two years. No implant failure was found during follow-up. Conclusions Early treatment with posterior short segment pedicle screw fixation and transpedicular intracorporeal bone graft with allogenic bone can effectively correct local deformity, prevent late vertebral collapse and implant failure and is an ideal treatment method for thoracolumbar osteoporotic compression fracture.

OBJECTIVEThe present study was undertaken to design antisense oligodeoxynucleotides (AS-ODNs) of glial glutamate transporter-la (GLT-1a) and to evaluate the effectiveness of the designed AS-ODNs on the expression of GLT-1a.

METHODSFive sequences of GLT-1a AS-ODNs were designed according to the C terminus specific sequences of GLT-1a mRNA using antisense design software of IDT Com- pany. Western blot analysis was used to evaluate the inhibition effects of the five GLT-1a AS-ODNs on the expression of GLT-la.

RESULTSThe sequence of GLT-1a AS-ODNs with sequence of 5'-GGTTCTTCCTCAACACTGCA-3' could specifically inhibit the expression of GLT-1a in the hippocampal CA1 subfield of rats, while it had no effect on the expression of GLT-1b. This sequence showed similar inhibition on the expression of GLT-la in sham and ceftriaxone (Cef)-treated rats. It could also significantly inhibit the cerebral ischemic preconditioning (CIP)-induced up-regulation in the expression of GLT-1a. The magnitude of the inhibition in sham, Cef- or CIP-treated rats was similar by more than 60%.

CONCLUSIONFrom the designed five sequences of GLT-1a AS-ODNs, we obtained an effective sequence which can specifically inhibit the expression of GLT-1a.

Objective HLA-G widely participates in immune tolerance by its combination with immunoglobulin-like tran-scripts IL-2 and IL-4 on the surface of dendritic cells (DCs).The aim of the article was to explore the effects of recombinant adnovirus-mediated HLA-G transfection in macaca mulatta immature dendritic cells on T cell proliferation . Methods Marrow blood was collected from macaca mulattas by the puncture needle after anesthesia .Density gradient centrifugation method was applied in separating mononuclear from the extracted blood on which CD 34+cells were collected and pu-rified by means of immunomagnetic separation .Small doses of cyto-kines were added to get the immature dendritic cells after induced dif-ferentiation of CD34+cells.After the recombinant adnovirus-mediated HLA-G transfection in macaca mulatta immature dendritic cells , observation was done on the viral infection efficiency and western blot was used in detecting the expression of HLA -G in immature den-dritic cells.Taking T cells in macaca mulatta as responders and DCs transfected by recombinant adnovirus -mediated HLA-G as stimu-lators, mixed lymphocyte test was conducted .T cells were divided into 5 groups: mDC group ( mature DCs ) , imDC group ( immature DCs), imDC(L) group(addition of 100 ng/mL lipopolysaccharide after getting imDC at 7th day) , imDC(V) group (imDCs infected by recombinant adnovirus-mediated HLA-G) , imDC( L+V) group ( imDCs infected by recombinant adnovirus-mediated HLA-G along with the addition of 100 ng/mL lipopolysaccharide in culture process ) . Results We obtained the immature dendritic cells and recom-binant adenovirus of HLA-G expressed in these cells .Flow cytometry showed DC purity was up to 92.3 %, imDC purity was up to 72.39%and positive percentage of CD 4+T was greater than 80%.In comparison with imDC group ,the proliferation of stimulated T cells in mDC and imDC(L) groups was obviously intensified (P<0.01).In comparison with imDC(V) group, the proliferation of stim-ulated T cells in imDC, mDC, imDC(L), and imDC(L+V) groups was obviously intensified (P <0.01).In comparison with imDC(L+V) group, the proliferation of stimulated T cells in mDC and imDC(L) groups was obviously intensified(P<0.01). Conclu sion Im-mature DCs infected by recombinant adnovirus can inhibit the proliferation of T cells effectively .

Objective Less research has been done in the influence of two-child pohcy on mode of delivery.The article aimed to investigate the rates of cesarean section before and after two-child policy along with indications and complications in order to provide scientific basis and solution for improving the vaginal delivery rate.Methods Retrospective analysis was conducted on medical record data of 7044 puerperas in Nanjing General Hospital of Nanjing Military Region before (3,526 women from January 1,2012 to December 31,2013)and after (3,518 women from January 1,2015 to December 31,2016) two-child policy.Before the two child policy there were 3122 primiparas and 404 multiparas,after two-child policy there were 2546 primiparas and 972 muhiparas.Comparison was done between two groups in the aspect of vaginal delivery rate,cesarean section rate and the distribution of primiparas in choosing the mode of delivery.Results The vaginal birth rate of women before and after the policy was 59.22％ and 63.22％ respectively,among which the rate of vaginal delivery of primiparas increased dramatically from 60.57％ before the policy to 66.10％ after the policy(P＜0.05).After two-child policy,the primiparas cesarean section indication with social factors,macrosomia decreased,which was 12.67％ vs 5.68％、16.65％ vs 11.82％,respectively.However,the rate of cesarean section with in-vitro fertilization increased,which was 5.52％ and 10.10％ respectively (P ＜ 0.05).Conclusion After two-child policy,the puerperant,especially for the primiparas were more likely to choose vaginal spontaneous delivery.At the same time,the proportion of the primiparas caesarean section also changed.The mode of delivery should depend on corresponding indications properly.

Objective To study the regulatory effect of triptolide(TP)on the angiogenesis of coll-agen-induced arthritis(CIA) rats.The effect of TP on arthritis is also explored.Methods After the model of CIA was established,the articular volume was measured and the synovium was examined with regular HE stainand the inflammation and pathological changes were evaluated.In addition,the vascular endothelial growth factor (VEGF),basic fibroblast growth factor (bFGF)and endostatin protein expressions in synovium and serum were tested.The micro-vessel density (MVD) of synovium was also measured by caulating CD34 level.Results The expressions of VEGF,bFGF and MVD in CIA rats'synovium and serum were evidently higher than the control group(X2=65.3,31.6,q=9.2,P＜O.01,respectively),while the expression of endostatin showed no statistical difference with controls (X2=0.8,P＞0.05).After treated with TP,the expressions of VEGF,bFGFand MVD decreased markedly(X2=19.7,6.0,q=6.5,P＜O.01,respectively),but the pmtein expression of endostatin significantly increased (X2=3.9,P＜O.05).However,only the expression of endostatin increased significantly after treated with MTX (X2=17.9,P＜0.01).Conclusion Imbalance in growth factors prnduction may play an important role in the process of arthritis development.Re-establishing the balance of growth factors maybe one of the mechanisms of TP in the treatment of arthritis.
