RESUMO
OBJECTIVE@#To test the performance of CHADS-VASc score in predicting stroke recurrence in first-ever ischemic stroke survivors without atrial fibrillation (AF).@*METHODS@#A total of 768 patients were included in this study, including 475 male (61.85%) and 293 female patients (38.15%) with a mean age of 61.52±12.59 years (17-90 years). The baseline information of the patients was collected by face-to-face questionnaire survey and electronic medical record review, and their follow-up information was collected by telephone follow-up once every 3 months. Chi-square test and Wilcoxon rank sum test were used to compare the baseline characteristics between the patients regularly followed up and those withdrawn from the study. The area under the ROC curve (AUC), sensitivity, specificity, positive likelihood ratio and other indicators of CHADS-VASc score were determined, and C-index based on Cox proportional hazards model was used to evaluate the performance of CHADS- VASc score in predicting the risk of stroke recurrence in patients at different time points during the follow-up.@*RESULTS@#The 1-year, 3-year, and 5-year recurrence rate of stroke was 10.59%, 20.45%, and 29.46% in these patients, respectively. The AUC value, Optimal Operating Point (OOP) and the corresponding positive likelihood ratios (LR+) for predicting stroke recurrence were 0.558 (95%: 0.492-0.624), 4.5, and 1.256 at 1 year; 0.574 (95%: 0.517-0.630), 4.5, and 1.397 at 3 years; and 0.604 (95%: 0.548-0.661), 4.5, and 1.655 at 5 years, respectively. Sensitivity analysis of congestive heart failure showed that the predictive effect of CHADS-VASc score was basically unchanged.@*CONCLUSIONS@#CHADS-VASc score can be used to predict the 3-year and 5-year risk of stroke recurrence in first-ever ischemic stroke survivors without AF. The score has a better prediction ability for long-term stroke recurrence, but the prediction value remains low, suggesting the need to further improve the score or establish a new score for predicting stroke recurrence.

OBJECTIVE@#To investigate the association between alcohol drinking and all-cause death in patients with ischemic stroke.@*METHODS@#Between January, 2010 and July, 2018, consecutive patients with first-episode ischemic stroke admitted in the West China Hospital, Sichuan University were enrolled, and all the patients were followed up every 3 months.Chi-square test was used to compare the differences in the baseline characteristics between the pre-stroke drinkers and the nondrinkers.The Cox regression model was used to analyze the effects of drinking status, drinking years, drinking frequency, average single alcohol intake before stroke and drinking status during the follow-up period on the mortality of patients after discharge.@*RESULTS@#A total of 855 patients with ischemic stroke were enrolled, and deaths occurred in 140 of these patients.Chi-square test showed significant differences in gender ( < 0.001), weekly physical exercise time (=0.035), smoking ( < 0.001), and heart disease ( < 0.001) between the pre-stroke drinkers and nondrinkers.Multivariate Cox regression analysis showed that drinking during the follow-up period (=0.001), drinking for less than 28 years before stroke (=0.035) and a moderate drinking frequency (5 to 20 times per month for males and 4 to 9 times per month for females; =0.030) were associated with a lowered risk of death after discharge.No significant effects of pre-stroke drinking status or average single alcohol intake were found on death after ischemic stroke.@*CONCLUSIONS@#The drinking years and drinking frequency before stroke and drinking status during the follow-up period are related to the all-cause mortality in patients with ischemic stroke.Investigations of the more specific variables of drinking behaviors during the follow-up period are needed to further clarify the association between drinking and death after ischemic stroke.

Objective: To identify related factors associated with unprotected anal intercourse (UAI) among HIV-positive men who have sex with men (MSM) in the context of knowing their HIV infection status. Methods: HIV positive MSM who known that they had been infected with HIV for more than 6 months and accepted follow up services were recruited by convenience sampling method in Chengdu 2015. Semi-structured questionnaire was used to collect their information, such as demographic characteristics, antiviral therapy and sexual behavior characteristics etc. Logistic regression model was used for univariate and multivariate analyses. Results: A total of 330 HIV- positive MSM were recruited, 201 eligible MSM were interviewed. The prevalence of UAI in recent six months was 18.41% (37/201). The results of multivariate logistic regression analysis revealed that the number of anal intercourse with male ≥3 in last month (OR=6.22, 95%CI: 1.88-20.56), low education level (OR=7.29, 95%CI: 1.36-39.16), married, divorced or widowed status (OR=4.65, 95%CI: 1.13-19.17), homosexual cohabitation (OR=3.32, 95%CI: 1.01-10.95) were the risk factors related with UAI among the HIV-positive MSM. Conclusion: Frequent homosexual anal intercourse, low education level, married, divorced or widowed status and homosexual cohabitation might be the risk factors related with UAI in HIV-positive MSM in Chengdu.

RESUMO
<p><b>OBJECTIVE</b>To investigate the difference in mental health status of oral tumor patients and their spouses, and explore the differences on the basis of relevant materials.</p><p><b>METHODS</b>Forty patients with oral cancer, eighteen spouses, and thirty-five patients with oral benign tumor were diagnosed in the West China Hospital of Stomatology between December 2011 and August 2012 and assessed with symptom checklist-90 (SCL90) (the 5-grade scoring). Participants were assessed independently according to their conditions. Blood samples were obtained from the participants by syringe on the second admission day. A method was developed to determine the concentrations of catecholamine and glucocorticoid in the serum using high performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS).</p><p><b>RESULTS</b>The scores for compel, depression and rests in the cancer group and benign tumor group were statistically significant (P<0.05). The scores for compel, dread and stubborn in the cancer group and their spouses were statistically significant (P<0.05). The differences between the total and other monomial factor scores were not statistically significant. However, the contents of epinephrine, norepinephrine, cortisone and hydrocortisone in the serum, as determined by HPLC-MS/MS, were significantly different (P<0.001).</p><p><b>CONCLUSION</b>Psychiatric factors do not show a simple factor effect on patients. Symptoms of patients may be based on tumorigenesis and developed in small molecules. Further research is required.</p>

RESUMO
Anti-inflammatory and analgesic and antipyretic and gastrointestinal ulcerogenic activities of ketoprofen 2-(3-benzoylphenyl -propionic acid) were investigated in experimental animals.Anti-inflammatory potency of ketoprofen was almost equal to that of indomethacin in carrageenin, yeast or nystatin-incluced hind paw edema and in acetic acid-induced increase of vascular permeability.Oral analgesic ED50-value of ketoprofen was on the whole campa-rable to that of indomethacin.Ketoprofen exerted a strong antipyretic action at oral doses in rats and its potency (ED50-1.22 mg/kg) was 2.3 times of that of indomethacin. However, ulcerogenicity of ketoprofen was weeker than that of indomethacin safety index and therapeutic index (SUD60/ED50 and LD60/ED40) of ketoprofen were greater than that of indomethacin and extremely great (the index ratio=114.7/4.5 ) in the antipyretic activity. It was suggested from these findings that ketoprofen is a potent anti-inflammatory drug with analgesic and antipyretic actions superior to indomethacin and a wide safety margin.
