We observed the catabolic characterestics of in vitro prepared nonenzymatically glucosylated low density lipoprotein (glcLDL) in mouse peritoneal macrophages (M?) and human monocyte line (U_(937); and found that glcLDL did not stimulate the increase degradation of glcLDL significantly nor did the accumulation of glcLDL cholesterol in mouse peritoneal M?. However the degradation of glcLDL by U_(937) cells was positively proportional to the concentration of glcLDL. The pre-treatment of U_(937) cells with 12-O-tetradecanoylphorbol 13-acetate (TPA) increased the degradation of glcLDL and was also positively proportional to the concentration of glcLDL. The relationship between these phenomena and the accelerated developement of atherosclerosis in diabetes mellitus was discussed.

Trastuzumab combined with chemotherapy improves overall response rate in women with HER2-overexpressing breast cancer.However,therapeutic resistance to trastuzumab typically occurs after several months of starting therapy and overall survival does not improve significantly.Studies have reported that the potential mechanisms of resistance to trastuzumab are mainly related to the signal pathway activation from receptor tyrosine protein kinases outside of the HER family and the amplification of the PI3K-AKT pathway.Novel target therapies such as tyrosine kinase inhibitors,PI3K inhibitors are approved as substitutes for the treatment of HER2-overexpressing breast cancer,but the response to each single-agent tends to be short-lived.Several large randomized adjuvant trials have showed that novel molecular targeted therapies combinations will markedly limit or eventually abrogate acquired resistance to primary trastuzumab therapy.

In order to improve the accuracy of classification with small amount of motor imagery training data on the development of brain-computer interface (BCD systems, we proposed an analyzing method to automatically select the characteristic parameters based on correlation coefficient analysis. Throughout the five sample data of dataset IV a from 2005 BCI Competition, we utilized short-time Fourier transform (STFT) and correlation coefficient calculation to reduce the number of primitive electroencephalogram dimension, then introduced feature extraction based on common spatial pattern (CSP) and classified by linear discriminant analysis (LDA). Simulation results showed that the average rate of classification accuracy could be improved by using correlation coefficient feature selection method than those without using this algorithm. Comparing with support vector machine (SVM) optimization features algorithm, the correlation coefficient analysis can lead better selection parameters to improve the accuracy of classification.

Objective:To evaluate the utilization of Kanglaite injections in lung cancer patients in 11 hospitals of Zhejiang and analyze the prescription data. Methods: Totally 40-day prescription data of the patients with lung cancer in 11 hospitals of Zhejiang were withdrawn every year from 2009 to 2013. The data in respect of the consumption sum, DDDs, department distribution and medical insurance category of Kanglaite injections were analyzed. Results: The consumption sum of Kanglaite injections used in the patients with lung cancer in 11 hospitals of Zhejiang showed an upward trend year by year, the growth in 2011 and 2012 was the fastest, and the sum in 2012 was 1. 77-fold of that in 2009. The consumption sum proportion of Kanglaite injections in total amount of drug consumption rose after the first drop. The top 3 departments were oncology, radiotherapy and thoracic surgery in the five years. The dosage and DDDs of Kanglaite injections were also in an increase trend year by year, and the growth in 2011 and 2012 was the fastest. Conclusion:The utilization of Kanglaite injections in the patients with lung cancer in Zhejiang area shows a continuous rapid growth momentum, therefore, it is still essential to strengthen the reasonable application in clinics.

Objective To investigate related factors of hypersensitivity reactions in patients undergoing paclitaxel chemotherapy for cervical cancer and provide measures for prevention of the side effects.Methods A ret-rospective survey was taken to analyze the clinical data from 186 cervical cancer patients who accepted paclitaxel chemotherapy from January 2013 to December 2014.SPSS 17.0 was used for single factor analysis and multi -factor logistic regression analysis.Results Among the 186 cervical cancer patients enrolled in this study,34 cases occurred hypersensitivity reactions.The incidence rate of anaphylaxis was 18.3%.Both eosinophil count of more than 0.2 × 109 /L(χ2 =4.171,P <0.05)and history of drug allergy(χ2 =10.667,P <0.01)were not merely risk factors of anaphylaxis,but also independent risk factors(OR =4.691,2.257,all P <0.01 ).Conclusion The incidence of hypersensitivity after paclitaxel chemotherapy in cervical cancer patients is high.Eosinophil count ≥ 0.2 ×109 /L before chemotherapy and history of drug allergy are not merely risk factors of anaphylaxis,but also independent risk factors,which require more attention.

Background Prevalence of dry eye is significantly inceasing in postmenopausal women than that in men,suggesting that sex hormone plays a role in the pathogenesis of dry eye.In addition,dry eye might become worse following estrogen therapy in postmenopausal women.However,whether application of androgen can ameliorate dry eye is being concerned.Objective This study was to investigate the effect of androgen on tear film of ovariectomized female rats.Methods Forty-eight 3-month-old sexually mature female Wistar rats were randomized into the normal control group,sham group,ovariectomy (OVX) model group and testosterone-injected group.OVX models were established by bilateral ovaries enucleation in the rats of the model group and testosterone-injected group,and then androgen (3.75 mg/kg) was intramuscularly injected since 5 months after OVX at 3-day interval for 6 weeks.Only intraperitoneal fat was cut off in the sham group.In 6 weeks after injection of androgen,serum androgen concentration detected and Schirmer Ⅰ test (S Ⅰ t),tear film break-up time (BUT) were performed.The rats were sacrificed to prepare the corneal and conjunctival samples.The expression of MUC5AC in conjunctival tissue was examined by immunofluorescence staining,and the microstructure of corneal cellular surface was observed under the scanning electron microscope before and 6 weeks after application of androgen.Animals in this study were treated in accordance with Animal Experimentation Ethic Committee Guidelines of Southern Medical University and the study protocol was approved by Ethic Committee of this University.Results The mean serum testosterone concentration was (1.83 ±0.12) ng/ml,and S Ⅰ t or BUT was (3.63-±0.26)mm/5 minutes or (3.73-0.38) seconds,respectively,in the OVX model group,which was significantly declined in comparison with (2.56 ±0.14) ng/ml,(7.47±0.66) mm/5 minutes or (9.57 ±0.76) seconds in the normal control group (all at P =0.000).However,the serum testosterone concentration was (3.38±0.24) ng/ml,S Ⅰ t was (6.37 ±0.45) mm/5 minutes and BUT was (7.54±0.55) seconds in the testosterone-injected group,which was significantly higher than that in the OVX model group (all at P =0.000).The positive staining of MUC5AC in rat conjunctival tissue weakened in the OVX model group compared with the normal control group,and the fluorescence intensity in the testosterone-injected group was stronger than that in the OVX model group.Regularly arranged microvilli and cell metabolism hiatus on the surface of corneal cells were seen in the normal control group and the sham group;while the microvilli were shorter and irregularly arranged,and the cell metabolism hiatus were disappeared in the OVX model group.However,microvilli and cell metabolism hiatus were close to normal ones in the testosterone-injected group.Conclusions Deterioration of tear secretion and instability of tear film are are probably associated with the lower serum androgen levels in castrated female rats.Systemic supplement of androgen can promote tear secretion,improve tear film stability and alleviate ocular surface damage.
