Efficacy comparison of rosuvastatin and atorvastatin in the treatment of atherosclerosis and drug safety analysis.

Previous studies have shown that the commonly used statin lipid lowering drugs can delay the progression of atherosclerotic plaque. Atorvastatin can stabilize atherosclerotic plaque, but it can not reverse atheromatous plaque. This study will compare the efficacy of rosuvastatin and atorvastatin in the treatment of atherosclerosis and try to prove that the use of statins can improve peripheral atherosclerosis and reverse atherosclerotic plaque. The results showed that 10 mg rosuvastatin was more effective than 20 mg atorvastatin in lowering serum lipid level and elevating ABI index, ABI as rosuvastatin group (0.782±0.236) and atorvastatin group(0.541±0.196). After 6 months of treatment, the carotid artery IMT in rosuvastatin group and atorvastatin group decreased compared with before treatment, and the difference was statistically significant (P<0.05). The TC/mmol⋅L-1 is 2.83±0.56 in rosuvastatin group and 3.24±0.71 in atorvastatin group. In addition, rosuvastatin did not increase the risk of adverse reactions compared with atorvastatin. The results confirm that statin therapy can improve peripheral atherosclerosis and reverse atherosclerotic plaques.

Investigation and Analysis of the Situation of Methadone Hydrochloride Maintenance Treatment in Drug Addicts from Zhongshan and Their Demands / 中国药房

OBJECTIVE:To provide reference for improving therapeutic efficacy of methadone hydrochloride in maintenance treatment for drug addicts.METHODS:A questionnaire survey was conducted among drug addicts from outpatient department of drug maintenance treatment in 2 hospitals of Zhongshan City about their situation and demands.The data were statistically analyzed.RESULTS:A total of 101 questionnaires were distributed,and 88 effective questionnaires were recovered with effective recovery of 87.13％.64.77％ of the respondents had abused one or more drugs (narcotics) in the last year except for methadone hydrochloride;among them,the frequency of heroin abuse was the highest,which is 31.31％,followed by Qutong tablet,valium,meth,tramadol,etc.72.73％ of the respondents said they could stick to methadone hydrochloride maintenance treatment completely.The dosage of methadone was relatively dispersed,and the average dosage was 75.80 mL/time;the proportion of 71-80 mL/time was high,accounting for 26.14％.The average score of respondents' family support was (6.22 ± 1.88) and the average score of social support was(32.73 ± 6.94).The proportions of general,poor and very poor economic condition were 52.27％,22.73％,14.77％,respectively.The main demand of the top 5 respondents were to eliminate social discrimination (38.64％),employment (35.23％),psychological emotional support (35.23％),to reduce methadone hydrochloride dose (32.95％),assisting to reduce relapse (28.41％),respectively.CONCLUSIONS:The majority of the addicts who receive methadone hydrochloride maintenance treatment are male and middle-aged and young,their relative economic status is poor,and their family care and social support are unsatisfactory.The vast majority of them can adhere to methadone hydrochloride maintenance treatment completely or basically,most of which still abuse other drugs (narcotics) and have many demands.It is necessary to connect "biological-psychological-social" mode of medical treatment through social work intervention service mode,and conduct comprehensive intervention in order to better meet the relevant requirements and improve therapeutic efficacy of methadone hydrochloride maintenance treatment.

Tea polyphenol inhibits colorectal cancer with microsatellite instability by regulating the expressions of HES1, JAG1, MT2A and MAFA / 中西医结合学报

Objective: To investigate the mechanism of tea polyphenol in inhibiting microsatellite instability (MSI) of colorectal cancer. Methods: Using LoVo cells and SW480 cells treated with aqueous solution of tea polyphenol, cell proliferation was detected by methyl thiazolyl tetrazolium (MTT) method, changes in microsatellite sequences were detected by genescan method and changes in gene expression of LoVo cells were detected by illumina expression arrays and quantitative real-time polymerase chain reaction (PCR). Results: The proliferation inhibition rates of LoVo and SW480 cells treated with tea polyphenol increased with the increasing of drug concentration and showed an increasing tendency with time. The proliferation inhibition rate of LoVo cells with tea polyphenol was higher than that of SW480 cells, and there was a significant difference in the proliferation inhibition rates at 24 h, 72 h and one week. The microsatellite sequence of LoVo cells treated with tea polyphenol remained stable. The gene expression arrays and quantitative real-time PCR suggested that tea polyphenol inhibited the gene expressions of MT2A, MAFA, HES1 and JAG1 nearly two-fold over controls. It was also found that tea polyphenol inhibited the BAX and p38 genes with a more than two-fold difference but did not significantly inhibit the nuclear factor-κB pathway. Conclusion: Tea polyphenol significantly inhibited the proliferation of MSI colorectal cancer cells and stably maintained the microsatellite state in MSI colorectal cancer. Tea polyphenol inhibited the gene expressions of HES1, JAG1, MT2A and MAFA, up-regulated the gene expression of BAX and down-regulated that of P38. Further research is required to investigate how these pathways are interrelated.

Comparison of Ku protein Expression in CNE1 and CNE2 nasopharyngeal carcinoma cell lines / 中华放射肿瘤学杂志

Objective Radiosensitivity is highly correlated with DNA doub le stra nd breaks(DSBs). The repair of human DSB is possible mainly through nonhomologou s DNA end joining(NHEJ)pathway. This study was designed to determine the relat ionship between expression of 70Ku/ 80Ku prot ein (a modulating subunit of DNA-PK, which is an important component in NHEJ pathway) and radiosensitivity of nasoph aryngeal carcinoma cell lines. Methods Radiosensitivity parameters of the nasoph aryngeal carcinoma cell lines were obtained by the colony forming assay and radi ation dose-survival curve was done by linear quadratic model. Western blot was p erformed to determine the expression of 70Ku and 80 Ku in total extract of CNE1 a nd CNE2 at baseline level、different time after 4?Gy irradiation、12 h after di ff erent doses of irradiation. To perform a semi-quantitated assay of protein expr e ssion, the optic density (OD) value of each band was estimated by automatic imag e analysis system. Results Surviving fraction of CNE1 was higher than those of CNE2 at each dose point. Mean inactivation dose was higher in the CNE1(2.35)t han that in the CNE2(1.11), but the quantity of 70Ku/ 80Ku in either cell line was similar at both baseline and postirradiation levels. Conclusions CNE2 is mo re radiaosensitive than CNE1; as there was no marked correlation observed betwee n the quantity of Ku protein and radiosensitivity of the nasopharyngeal carcinom a cell lines. X-irradiation cannot result in any change in total quantity of Ku protein.
