METHODS:Using SERVQUAL scale,combining the situa-tion of pharmacy O2O platform development in China,the reliability,safety and aspects of O2O platform were analyzed to sum up primary evaluation index of pharmacy O2O platform service quality. Based on this,the expert interviews questionnaire was de-signed. According to the questionnaire results,indicators were modified and empowered to construct the pharmacy O2O platform service quality evaluation model;the reliability and validity of model were validated. RESULTS & CONCLUSIONS:According to the connotations of each dimension analysis in the SERVQUAL scale and expert interview results of pharmacy O2O platform ser-vice quality,pharmacy O2O platform service quality evaluation model is constructed,including five indicators as“reliability”“se-curity”,and 18 secondary indexes as the“number of platform pharmacy”“pharmacy qualification show”“pharmacy type”. The re-sults of model index reliability and validity verification show that model construction is reasonable and can provide reference for platform operators improving service quality. Follow-up research should give full consideration to the Chinese consumer behavior habits,personal preferences and other factors to build more suitable pharmacy O2O platform service quality evaluation model in China.

The effect of 131I therapy for primary and metastatic lesions of thyroid carcinoma depends on the ability of iodine uptake.The loss or down-regulation of iodine-metabolizing genes represents dedifferentiation of DTC,which results in the disability to take up and accumulate 131I and eventually leads to radioiodine-refractory DTC (RR-DTC).The management of RR-DTC is extremely difficult and the prognosis is poor.It is important for the treatment and prognosis of RR-DTC to investigate the mechanism of redifferentiation.The up-regulation of thyroid iodine-metabolizing genes expression,inhibition of the changes in epigenetic modifications and intervention of the abnormal activation of signaling pathways are reviewed in this article.

Objective To analyze the prognosis and risk factors for antineutrophil cytoplasmic antibody?associated vasculitis (AAV) patients on maintaining dialysis. Methods AAV patients on maintaining peritoneal dialysis (PD) or hemodialysis (HD) in First Affiliated Hospital Zhejiang University from June 2007 to June 2015 were included, and were followed up until death, kidney transplant, changed dialysis modalities or January 31, 2016. Patients were divided into PD group and HD group for comparison. Their survival rates and risk factors were analyzed by Kaplan?Meier analysis and COX regression model respectively. Results A total of 123 cases were chosen, with a median duration of dialysis for 854 (388, 1573) days, and with 88 cases (71.5%) on HD and 35 cases (28.5%) on PD. Fifty?two patients (42.3%) were more than 65 years old. At the median follow?up time of 36 months, 39 patients (31.7%) died. The main causes of death were cardiovascular events (30.8%) and infection (23.1%). COX regression analysis showed that patients older than 65 years old (HR=3.289, P=0.001), with cardiovascular disease (HR=3.241, P=0.003) and interstitial pneumonia (HR=2.173, P=0.048) at the dialysis onset were independent risk factors affecting survival. Conclusions Factors including age (older than 65 years), pre?dialysis cardiovascular disease and interstitial pneumonia were independent risk factors affecting survival of AAV patients on maintaining dialysis, then infections and cardiovascular events were the main causes of death.

This study is to investigate the mechanism of human promyelocytic leukemia HL-60 cells proliferation induced by alteronol in vitro. Human promyelocytic leukemia HL-60 cells cultured in vitro were treated with different concentrations of alteronol. Inhibition rate was detected by SRB assay. Cellular morphological changes were observed by Hoechst and AO/EB (acridine orange/ethidium bromide dye) staining. The apoptosis rate was determined by Annexin V-FITC/PI assay. Cell cycle distribution was determined by flow cytometry. Western blotting analysis was carried out to determine the cell cycle related proteins. The proliferation of HL-60 cells treated with alteronol was inhibited in a concentration-dependent manner. Based on cell viability assay, observation on cell morphology and apoptosis rate, it confirmed that alteronol played an obvious role in proliferation inhibition of human promyelocytic leukemia HL-60 cells, but it did not induce apoptosis in human promyelocytic leukemia HL-60 cells in different concentrations groups. Alteronol could effectively inhibit the proliferation of human promyelocytic leukemia HL-60 cells inducing cell cycle arrest at G1 phase, as well as, alteration expression of cell cycle proteins level of CyclinD1 and pRb.
