Objective To up-regulate the expression of Glil gene in periodontal ligament stem cells ( PDLSCs) and to explore the effect of Glil gene on PDLSCs proliferation and osteogenesis differentiation by establishing Glil gene adenovirus vectors. Methods Subcloned Glil to viral backbone vector Adtrack-CMV and transfered the established vector to 293T cells, which was to acquire the virus particles. Trans-fected aim cells,namely PDLSCs,with these virus. Detected its effect on PDLSCs proliferation with CCK-8 assay, and detected the expression of Glil and the bone-related markers ALP and Runx2 through Western blot. Results An adenovirus vector, which were over expressed Glil gene, was successfully constructed and transfected to PDLSCs. Compared with the empty vector group and normal group, the over expressed one had a much slower proliferation rate in CCK-8 assay (P=0. 003). Western blot showed that ALP and Runx2 can be overexpressing os-teogenic differentiated after PDLSCs successfully transfected with the Glil gene. Conclusion Over expressing Glil gene would lead to a much slower proliferation rate in the PDLSCs and an increase of the bone-related markers. It is concluded that Glil can enhance the osteogenic dif-ferentiation capacity in PDLSCs.

Aim: To prepare a novel contraceptive patch containing gestodene(GEST) and ethinylestradiol(EE), and to study the in vitro characterization and in vivo contraceptive effect. Methods: Double-layer technique was applied to sustain steady 7-day permeation flux of drugs. Polariscope examination was carried out to observe the drug distribution behavior in the patch. Uniformity, adhesion, skin irritation, release and permeation tests were conducted to evaluate in vitro characterization. Anti-implantation and anti-fertility experiments were carried out to investigate its contraceptive effect. Results: The in vitro release profiles of both drugs were in accordance with Higuchi equation. The daily permeated amount of GEST per 10 cm2 patch was about 75 μg while the amount of EE was 30 μg.The in vitro transdermal permeation of both drugs from the patches displayed a zero-order process. Permeation rate constants were 0. 377 μg/(cm2·h) for GEST, and 0. 092 μg/(cm2· h) for EE, respec-tively. After transdermal administration, the embryonic number of the test groups was zero, and the uterus coefficients of those groups were significantly reduced compared with those of the control group (P < 0. 01). Conclusion: Double-layer transdermal drug delivery system(TDDS) could allow the steady 7-day permeation flux of drugs when the drug ratio between the immediate-release layer and the reservoir layer was 1:4. In vivo charac-terization demonstrated its contraceptive effects. The prepared novel patch might be a promising non-oral contra-ceptive preparation.

Aim To investigate the effects of high glu-cose on cholesterol metabolism in renal tubular cells and the intervention of the anthocyanins. Methods HK-2 cells were grown in the DMEM medium supple-mented with 10% FBS and were divided into 5 groups:normal glucose group, high glucose group, mannitol group, C3G group and Cy group. Effect of anthocya-nins on cell viability was detected with MTT, and cho-lesterol accumulation was detected with Amplex Red Cholesterol Assay kit and Filipin staining. Expression of ABCA1 was detected with RT-qPCR and Western Blot. Results In compared with control groups, HG significantly promoted cholesterol mass inside the cell and decreased the cholesterol concentration in the me-dium after treatment for 24 h or 48 h. The levels of mRNA and protein of ABCA1 were detected with RT-qPCR and Western blot, and both were decreased in the presence of HG. Whereas treatment with C3G and Cy markedly attenuated HG-induced cholesterol mass inside the cell by up-regulating the expression of AB-CA1. Conclusions High glucose can reduce the ex-pressions of the ABCA1, and then decrease cholesterol efflux and increase the cholesterol accumulation in HK-2 cells. Anthocyanins can decrease cholesterol accu-mulation by up-regulating the expression of ABCA1.

Objective:
To observe the long-term efficacy and safety of autologous hematopoietic stem cell transplantation (AHSCT) for systemic sclerosis (SSc) patients.
Methods:
Between May 2007 and June 2009,4 patients with SSc were enrolled in the study. Peripheral blood stem cells were mobilized with cyclopho-sphamide (CTX) followed by granulocyte colony stimulating factor (G-CSF). Conditioning was performed with i.v. cyclophosphamide 50 mg·kg-1·d-1 for 4 days. The results of the modified Rodnan skin score (mRSS), thoracic high-resolution computer tomography and pulmonary function were collected after transplantation.
Results:
There was an improvement in mRSS, lung function and HRCT in the six months after AHSCT. Within six month to one year after transplantation, one patient had sustained and two patients recurred. After active treatments two patients were improved again. During the follow-up of 8.7 (4.1-9.8) years, three patients were stable and one patient died. Infection and hepatic function injury were the major complications. There was not transplant-related mortality.
Conclusion
AHSCT with CTX as a pre-conditioning regimen is safe and effective for SSc. The efficacy for patients with short course, rapid progress and edema is significant. However, long-term efficacy is poor, and long-term maintenance treatment is needed.

Objective To understand the relationship between perinatal factors and congenital hypothyroidism(CH)and provide scientific evidence for the prevention of CH. Methods A case-control study was conducted among 125 neonates with CH (case group) and 375 neonates without CH(control group)in Fujian Neonatal Screening Center from January in 2012 to December in 2013. Univariate and multivariate logistic regression analysis were performed to identify the risk factors to CH during perinatal period. Results Univariate logistic regression analysis indicated that compared with control group,gestational hypertension,gestational diabetes mellitus,gestational thyroid disease and older age of mother were the risk factors to CH,the difference was statistically significant (P<0.05) and the risk of CH was higher in female babies,preterm babies,post-term babies low birth weight babies,macrosomia,twins,babies with birth defects and infection in cases group than those in control group,the difference was statistically significant (P<0.05). Multivariate logistic analysis showed that older age of mother(OR=2.518,95%CI:1.186-5.347), gestational diabetes mellitus(OR=1.904,95%CI:1.190-3.045),gestational hypothyroidism or hyperthyroidism(OR=12.883 and 30.797,95%CI:2.055-80.751 and 3.309-286.594),preterm birth (OR=4.238,95%CI:1.269-14.155),and post-term birth(OR=12.799,95%CI:1.257-130.327),low birth weight(OR=3.505,95%CI:1.059-11.601),macrosomia(OR=3.733,95%CI:1.415-9.851), twin or multiparous delivery(OR=5.493,95%CI:1.701-17.735),birth defects(OR=3.665,95%CI:1.604-8.371)and fetal distress(OR=3.130,95%CI:1.317-7.440)were the high risk factors to CH (P<0.05). Conclusion CH was correlated with mother’s age,gestational diabetes,gestational thyroid disease as well as neonate’s birth weight and gestational age,foetus number,fetal distress and other complicated birth defects at certain degree. More attention should be paid to perinatal care to reduce risk factors and the incidence of CH.
