Objective:To explore therapeutic effect of rosuvastatin and atorvastatin treatment on levels of lipoprotein and inflammatory factors in patients with acute coronary syndrome (ACS) .Methods :A total of 74 ACS patients , who were treated in our department of cardiology from Mar 2008 to Feb 2014 ,were selected .According to random number table ,they were randomly and equally divided into rosuvastatin group and atorvastatin group .Therapeutic effect on 24d after administration ,levels of low density lipoprotein cholesterol (LDL‐C) ,high density lipoprotein cholesterol (HDL‐C) ,interleukin (IL)‐18 and C reactive protein (CRP) before and four weeks after treatment were compared between two groups .Results:On 24d after treatment ,total effective rat of rosuvastatin group was significantly higher than that of atorvastatin group (83.8% vs .75.7% , P< 0.05);after four‐week treatment , compared with atorvastatin group ,there were significant reductions in levels of LDL‐C [ (1. 8 ± 0. 2 ) mmol/L vs . (1.4 ± 0.1) mmol/L] ,IL‐18 [ (1.8 ± 0.2) vs .(1.4 ± 0.1)] and CRP [ (1.9 ± 0.3) pg/ml vs .(1.4 ± 0.2) pg/ml],andsignificantriseinHDL‐Clevel[(1.4±0.2)mmol/Lvs.(1.9±0.3)mmol/L]inrosuvastatingroup,P<0.05 all .Conclusion:Rosuvastatin therapy can achieve better adjusting lipid and anti‐inflammation effect than those of atorvastatin in patients with acute coronary syndrome ,which is worth clinical extending .

Objective:To analyze the application effect of integrated medical and nursing management model based on intelligent medical system in preventing postoperative breast cancer lymphedema.Methods:A total of 180 patients undergoing axillary lymph node dissection for breast cancer were selected in the Affiliated Hospital of Nantong University from July 2018 to August 2019. According to the random number table method, they were divided into treatment group and control group for 90 cases in each group, and finally completed the study: 86 cases in treatment group and 82 cases in control group. The control group was given routine health management, and the treatment group was given an integrated management model based on intelligent medical systems. After 6 months of follow-up, the two groups of patients were compared for their cognition of lymphedema, prevention behavior, incidence of lymphedema, and patient satisfaction.Results:The incidence, clinical manifestations, risk factors, prevention methods, and overall awareness rates of lymphedema in the treatment group were 82.56%(71/ 86), 84.88%(73/86), 83.72%(72/86), 83.72%(72/86), 83.72%(72/86), and the control group were 67.07%(55/82), 70.73%(58/82), 68.29%(56/82), 69.51%(57/82), 70.73%(58/82), the differences were statistically significant ( χ2 values were 4.046-5.508, P<0.05). The total scores of skin care, lifestyle, avoidance of upper limb compression, and prevention of lymphedema in the treatment group were (9.54±1.04), (30.45±2.45), (9.35±1.08), (58.92±8.20) points, and the control group were (8.12±1.32), (8.12±1.32), (8.74±1.14), (53.45±7.64) points, the differences were statistically significant ( t values were 3.561-7.764, P<0.01). The incidence of lymphedema in the treatment group was 9.30%(8/86), and that in the control group was 23.17%(19/82), the difference was statistically significant ( χ2 value was 5.985, P<0.05). Satisfaction was 95.35%(82/86) in the treatment group and 82.93%(68/82) in the control group, the difference was statistically significant ( χ2 value was 6.771, P<0.01). Conclusions:The integrated management of medical care and patients based on intelligent medical system can help improve the level of lymphedema cognition in patients with breast cancer surgery, promote the development of lymphedema prevention behavior, reduce the incidence of postoperative lymphedema, and improve patient satisfaction.

Objective This present study was to examine the prevalence and determinants of one-night-stand behavior among young men who have sex with men (YMSM).Methods A total of 403 YMSM aged 16 to 25 were recruited through internet promotion,extending activity and HIV VCT in Wuhan.Data was gathered through anonymous questionnaire.Binary logistic regression was used to examine factors associated with one-night-stand behavior.Results Of the 398 YMSM,48.99％ (195/ 398) reported having had casual sex in the last 6 months.Of the ones having had casual sex,34.29％ (60/175) and 28.65％ (49/171) reported using condoms consistently during anal or oral sexual contacts,respectively.These figures were lower than those of YMSM not having casual sexual contacts [with anal sex as 49.08％ (80/163) and oral sex as 38.85％ (61/157)].76.80％ (149/194) of the YMSM reported having had multiple sexual partners,with the figure higher than those without [33.15％ (60/ 181)] (P＜0.01).Results from the logistic regression analysis showed that the following factors seemed to be associated with casual sex activities among YMSM,including:often using intemet,(OR=4.89,95％ CI:1.90-12.54),taking illegal drugs (OR=2.72,95％ CI:1.60-4.63).Conclusions YMSM who bad engaged in casual sex,practicing unprotected sex or having multiple sexual partners,were recognized as high risk population.Targeted intervention programs are needed to decrease the one-night-stand behavior.Internct intervention strategy seemed an important method to serve the purpose.

Objective To investigate the expression of miR-155 in rats exposed to PM2.5 and its signifi-cance.Methods Thirty-two 12-weeks-old healthy male SD rats were randomly divided into PM2.5-primary expo-sure group (P1),PM2.5-three times exposure group (P3), saline-control group and blank-control group (O), with 8 rats in each group. The pathological changes of lung tissue of each group were observed by HE staining and the expressions of miR-155 in lung tissue of each group were measured by RT-PCR. The expressions of TNF-α, IL-6 and IL-1β in serum of each group were measured by ELISA.One-way ANOVA and LSD-t test were used for statistical analysis,and Pearson′s correlation analysis was used to evaluate the relationship between the levels of miR-155 and TNF-α,IL-6 and IL-1β. Results The expression of inflammatory cytokines TNF-α,IL-6 and IL-1β in P1 and P3 increased when compared with that in saline control group and blank-control group, and the amount of expression increased with the increase of the number of exposure and dose;the difference between groups was statistically sig-nificant(P<0.01).At the same time,with the increase of the dose and number of PM2.5,the inflammatory damage of lung tissue was enhanced.The expression of miR-155 in lung tissue also increased with the increase of the dose and number of PM 2.5,and it had significantly positive correlation with serum inflammatory cytokines(P<0.01),and had statistical significance. Conclusions The lung tissue of rats exposed to PM2.5 can produce inflammatory injury, and the damage is enhanced with the increase of exposure times and dose.The expression of miR-155 is positively correlated with inflammatory injury in rats.Consequently,miR-155 may participate in PM2.5-induced inflammatory lung injury in rats.
