Objective To investigate the changes of bone mineral density (BMD) and its causing factors in menopausal female patients with type Ⅱ diabetes mellitus (DM2). Methods Dual energy X ray absorptimetry was used to measure the BMD of lumbar spines (L 2-4 ) and proximal femur in 82 female patients with type Ⅱ diabetes and 46 normal controls. According to BMD, DM2 patients were divided into two groups (DM A and DM B). Fasting plasma glucose (FPG), fasting plasma insulin (FINS), fasting plasma C peptide (FCP), glycated hemoglobin (HbAc1), urine albumin excretion rate (UAER), and urine ? 2 microglobin (? 2 MG) were measured and compared between the two groups. Results BMD of lumbar spines (L 2-4 ), femoral neck and Ward's triangle in diabetic patients were significantly lower than that of the controls ( P

Objective To explore the influence of introducing standardized patient (SP) into problem-based learning (PBL) to the autonomous learning abilities for undergraduate nursing students based on clinical thinking training. Methods To select 2 classes randomly from full-time professional nursing undergraduate classes enrolled in 2012 from Tianjin university of traditional Chinese medicine, was divided into the experimental group and the control group by random number table method. The control group uses PBL teaching mode, and the experimental group adopts introducing SP into PBL teaching mode. Course lasts for 4 weeks, a total of 18 hours. To evaluate two groups nursing students′the percentage of asking questions by themselves and examination results in the end of the course, and evaluate nursing students′autonomous learning ability before and after the course and after three months of clinical practice respectively. Results The percentage of asking questions by themselves and examination results of the experimental group were 87.80%(36/41) and (84.24±5.12) points, (87.85±5.44) points, the control group were 68.89%(31/45) and (81.51±6.63) points, (84.40±7.96) points, the difference was statistically significant (χ2=4.46, t=2.13, 2.37, P<0.05);There was no statistical significance between two groups in the score of autonomous learning ability before the course (P>0.05), while after course and after three months of clinical practice of the experimental group were (93.71±9.56) points, (103.27±11.92) points, the control group were (85.47 ± 9.28) points , (91.36 ± 10.56) points, the difference was statistically significant (t=3.56, 4.89, P<0.01). Conclusions The teaching mode of introducing SP into PBL can train and improve the autonomous learning ability of undergraduate nursing students,and can provide reference for nursing teaching mode reform.

Objective:To analyze the risk factors of postpartum type 2 diabetes (T2DM) in patients with family history of diabetes mellitus with gestational diabetes mellitus (GDM).Methods:From January 2017 to January 2019, 275 patients with GDM and family history of diabetes were selected. According to the occurrence of postpartum T2DM, the patients were divided into postpartum normal group (207 cases) and postpartum disease group (68 cases). The clinical data of the two groups were compared, and the independent risk factors of postpartum T2DM were analyzed by logistic regression, and a line chart prediction model was constructed. Receiver operating characteristic (ROC) curve and calibration curve were used to evaluate the predictive ability of the model. X-tile software was used to obtain the integral truncation value of the line graph model, and survival curve was drawn and internal verification was carried out.Results:Of 275 GDM patients, 68 had T2DM after delivery, with a incidence rate of 24.73%. There were significant differences between the two groups in age, body mass index (BMI) before pregnancy, weight gain during pregnancy, fasting blood glucose during pregnancy and glycosylated hemoglobin during pregnancy (all P<0.05). There was no significant difference in pregnancy outcome between the two groups ( P>0.05). Age≥30 years, high pre-pregnancy BMI, weight gain≥6 kg during pregnancy, fasting blood glucose>5.8 mmol/L during pregnancy, and glycosylated hemoglobin>5.2% during pregnancy were independent risk factors for postpartum T2DM in GDM patients with diabetes family history (all P<0.05). The nomogram model predicted that the C-index value of postpartum T2DM was 0.912 (95% CI: 0.854-0.960), and the area under the ROC curve was 0.799 (95% CI: 0.742-0.856), with good discrimination; The calibration curve indicated that the accuracy of the model was good. According to the integral cutoff value of the line chart model, the probability of postpartum T2DM in GDM patients with family history of diabetes was divided into three groups: low (≤67.24 points), medium (>67.24 points and ≤129.82 points) and high-risk groups. The incidence rate of postpartum T2DM were 13.71%, 29.29% and 59.62%, respectively, with statistical significance (all P<0.05). Conclusions:Age≥30 years old, high pre-pregnancy BMI, pregnancy weight gain≥6 kg, pregnancy fasting blood glucose>5.8 mmol/L and pregnancy glycosylated hemoglobin>5.2% were independent risk factors for postpartum T2DM in GDM patients with family history of diabetes.

Alectinib, an inhibitor of anaplastic lymphoma kinase (ALK), was approved by the Food and Drug Administration (FDA) for the treatment of patients with ALK-positive non-small cell lung cancer (NSCLC). Here we investigated the reversal effect of alectinib on multidrug resistance (MDR) induced by ATP-binding cassette (ABC) transporters, which is the primary cause of chemotherapy failure. We provide the first evidence that alectinib increases the sensitivity of ABCB1- and ABCG2-overexpressing cells to chemotherapeutic agents in vitro and in vivo. Mechanistically, alectinib increased the intracellular accumulation of ABCB1/ABCG2 substrates such as doxorubicin (DOX) and Rhodamine 123 (Rho 123) by inhibiting the efflux function of the transporters in ABCB1- or ABCG2-overexpressing cells but not in their parental sensitive cells. Furthermore, alectinib stimulated ATPase activity and competed with substrates of ABCB1 or ABCG2 and competed with [125I] iodoarylazidoprazosin (IAAP) photolabeling bound to ABCB1 or ABCG2 but neither altered the expression and localization of ABCB1 or ABCG2 nor the phosphorylation levels of AKT and ERK. Alectinib also enhanced the cytotoxicity of DOX and the intracellular accumulation of Rho 123 in ABCB1-overexpressing primary leukemia cells. These findings suggest that alectinib combined with traditional chemotherapy may be beneficial to patients with ABCB1- or ABCG2-mediated MDR.
