In recent years, with the rapid development of antitumor targeted drug therapy, the preparation of antitumor liposomes and its targeting research have attracted attention of scholars. Anti-tumor targeted drug treatment requires the drug to reach the tumor site has a relatively high concentration and longer retention time, the tumor cells have a strong cytotoxic activity, while normal cells no significant side effects.The drug has an in vivo distribution and specificity for the target fine action.The preparation methods of liposomes include film dispersion method,reverse evaporation method,ethanol injection method,supercritical reverse phase evaporation method and freeze-drying method. Antitumor targeting liposomes can be divided into active targeting liposomes and passive targeting liposomes. Targeted liposomes can specifically target tumor cells by recognizing specific targets in the tumor tissue,thus enriching tumor cells and killing tumor cells. In this paper,the preparation of anti-tumor liposomes and the progress of its targeting,for future study and application of liposomes provide a reference.

Objective To analyze the clinical effect of probucol in prevention of contrast induced nephropathy(CIN) after percutaneous coronary intervention(PCI).Methods 96 patients with coronary heart disease requiring PCI surgery in our hospital were selected as the research subjects, and they were randomly divided into control group(48 cases) and observation group(48 cases).Both two groups were given traditional treatment, besides this, the observation group was given additional probucol (3 d treatment before and after operation,0.5 g/time,2 times/d).The renal function indicators such as serum creatinine (Scr), cystatin C(CysC), blood urea nitrogen(Bun), estimated glomerular filtration rate(eGFR), and the expression levels of C-reactive protein(CRP),interleukin-6(IL-6) and malondialdehyde(MAD) in the two groups 24 h,48 h, 72 h before and after PCI were observed and compared.And the adverse reactions during operation in the two groups were also recorded and compared.Results There were no significant differences in Scr,CysC,Bun and eGFR between the two groups before opertion(t=0.149,P=0.882;t=1.75,P=0.243;t=0.019,P=0.985).12 h after operation, the Scr,CysC,Bun and eGFR levels in the two groups were gradually increased,48 h post-treatment, the levels reached to the peak and showed a downward trend 72 h after operation;compared with the control group, the rise and decline in the observation group were more greater, and the differences were statistically significant (t=3.242,P=0.002;t=9.532,P<0.001;t=9.073,P<0.001;t=2.896,P<0.001).There were no significant differences in CRP,IL-6 and MAD between the two groups before operation (t=0.321,P=0.749;t=0.014,P=0.989;t=0.188,P=0.850).24 h after operation, the CRP,IL-6 and MAD levels in the two groups were gradually increased,48 h post treatment, the levels reached to the peak and showed a downward trend 72 h after operation;compared with the control group, the rise and decline in the observation group were more greater, and the differences were statistically significant (t=8.495,P=0.002;t=7.532,P<0.00;t=16.216,P<0.001).There were no obvious adverse reactions during operation in the two groups.Conclusion Probucol not only has lipid-regulating and atherosclerotic effects on patients with coronary heart disease, but also has certain preventive and clinical effects to CIN after PCI.Thus, it can be considered as a preferred drug for clinical prevention and treatment of CIN.

Objective To explore the association between C reactive protein (CRP)with prostatic cancer (PCa)and benign prostatic hyperplasia (BPH).Methods Retrospective analysis the 110 patients of the First Affiliated Hospital of Zhejiang University In January 2010 to August 2012 whose TPSA>4 ng/ml,postoperative pathology confirmed the diagnosis of 54 cases of prostate cancer,5 6 cases of benign prostatic hyperplasia.Detected serum CRP levels by using transmission turbidim-etry and TPSA levels by using chemiluminescence immunoassay of 54 PCa and 56 BPH patients.According to the Gleason score,PCa patients were divided into high-risk and low-risk PCa two groups,the differences among high-risk PCa,low-risk PCa and BPH groups were analyzed by nonparametric statistics analysis.Results The CRP level of high-risk PCa was 4.20~2.12 mg/L,the CRP level of low-risk PCa was 1.90~0.91 mg/L and the CRP levels in BNP patients was 1.49±0.87 mg/L,the high-risk and low-risk PCa serum CRP level obviously higher than that of patients with BPH,the differences were statistically significant (P<0.05).Conclusion Serum CRP levels of PCa patients were increased significantly,espe-cially in high-risk PCa patients.

AIM:To evaluate the poor vision condition and analyze the myopia etiological factor in primary school He'xi district of Sanya.
METHODS: A cohort of 1 218 subjects were recruited randomly from grade 1~6 of two primary schools. Visual activity test, dioptroscopy and risk factor questionnaire were evaluated.
RESULTS: The prevalence of poor vision was 29. 55%. The incidence of myopia increased with grade, and was significantly higher in girls than that in boys. The outdoor activity time of myopic pupil ( 7. 25 ± 5. 35h/wk ) was significantly lower than emmetropic pupil (11. 86±6. 65h/wk) ( P < 0. 05 ). The usage of electronic product ( TV, computater and cell phone) time of myopic pupil (13. 36±8. 35h/wk) was significantly higher than emmetropic pupil (7. 75±5. 83h/wk) (P<0. 05).
CONCLUSION: The increase of myopia incidence is closely related with sparing outdoor activity and excess usage of electronic product.
