[The effect and mechanism of transient continuous subcutaneous insulin infusion therapy on beta cell function, insulin resistance and vascular endothelial injury in newly diagnosed type 2 diabetes].

Objectives: To explore the effect of transient continuous subcutaneous insulin infusion (CSII) on ß cell function, insulin resistance and vascular endothelial injury in newly diagnosed type 2 diabetic patients and its potential mechanism.

Methods: Ten patients with newly diagnosed type 2 diabetes mellitus (T2DM) accepted CSII for two weeks. Intravenous glucose tolerance test (IVGTT) and hyperinsulinemia euglycemia clamp test were performed before and after CSII.

Bone mineral density and its relationship with body mass index in postmenopausal women with type 2 diabetes mellitus in mainland China.

Bone mineral density (BMD) and its association with body mass index (BMI) are uncertain in postmenopausal women with type 2 diabetes mellitus (T2DM) in mainland China. This study was performed to assess this association including 1,042 postmenopausal women with T2DM and 919 non-diabetic control subjects. Bone mineral density of the posteroanterior spine and of the left hip was measured by use of dual-energy X-ray absorptiometry.

[Herceptin plus adjuvant chemotherapy for the prognosis of patients with human epithelial growth factor receptor 2 positive early-stage breast cancer: a meta-analysis].

Objective: To evaluate the effect of herceptin(trastuzumab) plus adjuvant chemotherapy on the prognosis of patients with human epithelial growth factor receptor 2 (HER2) positive early-stage breast cancer by Meta-analysis.

Methods: Search all of randomized clinical trials (RCTs) on herceptin plus adjuvant chemotherapy for HER2 positive early-stage breast cancer in MEDLINE, EMBase, Cochrane library, Clinical Trails, ASCO Conference data, CHKD, Wanfang Database, VIP information, scholar.google.

[Isolation of differentially expressed genes in human osteoblast-like osteosarcoma cell line induced with 17beta-estradiol].

Objective: To obtain a serial differentially expressed cDNA fragments from human osteoblast-like osteosarcoma MG-63 cells induced with 17beta-estradiol and to find some estrogen-responsive genes.

Methods: Optimized cDNA representational difference analysis (RDA) was performed to isolate up-regulated expressed sequences between cDNA from MG-63 cell line treated with and without 17beta-estradiol. The sources of up-regulated expressed cDNA fragments were proved by Southern blot.

The effect of low dose nylestriol-levonorgestrel replacement therapy on bone mineral density in women with postmenopausal osteoporosis.

Objective: Recently our studies have shown that nylestriol in combination with levonorgestrel prevented bone loss, decreased bone turnover rate and increased the maximal loading of bone without obvious side effects in retinoic acid (RA) induced osteoporotic rats. In addition to the animal experiments, we evaluate the effect of Compound Nylestriol Tablet (CNT) on bone mineral density (BMD) in women with postmenopausal osteoporosis. Compound Nylestriol Tablet, which contains 0.

Age-related bone mineral density, accumulated bone loss rate and prevalence of osteoporosis at multiple skeletal sites in chinese women.

We investigated the age-related bone mineral density (BMD), accumulated bone loss rate (ABLR) and the prevalence of osteoporosis at different skeletal sites in Chinese women. BMD was measured at the anteroposterior (AP) spine, supine lateral spine (areal BMD at the midarea [mLat] and the whole region [Lat], volumetric BMD at the middle region [MVD] and total region [TVD]), hip (femoral neck [FN], trochanter [Troc] and Ward's triangle [Ward's]) and forearm (radius + ulna ultradistal [RUUD], 1/3 region [RU1/3] and total region [RUT]) using a dual-energy X-ray absorptiometry (DXA) fan-beam bone densitometer (Hologic QDR 4500A) in 2702 females aged from 5 to 96 years old. Data were analyzed by eight different regression models.
