ABSTRACT
Objective To examine the impact of loneliness on cognitive impairment among community-dwelling elderly people.Methods A cross-sectional survey was conducted between July and August 2015 with 895 community-dwelling elderly participants in four residential areas of Wuchang District,Wuhan.The Montreal Cognitive Assessment (MoCA) was used to measure cognitive function.Chi square test,t-test,and multivariate linear regression were used to analyze the data.Results Multivariate linear analysis showed that loneliness was independently and negatively associated with cognitive function among the participants (β=-1.2828,95％ CI:-2.27--0.30).Participants who felt loneliness recorded lower scores on visuospatial executive,attention,and language ability than those who did not (P＜0.05).Multivariate logistic analysis demonstrated that loneliness was also associated with cognitive function after adjustment for age and gender,with OR (95 ％CI) at 1.74(1.05 2.91) / 1.78 (1.07 2.94).Loneliness remained an independent risk factor for cognitive dysfunction after adjustment for age,gender,education level,monthly income,living arrangement,physical activity,mental activity,hypertension,diabetes,frequency of social interaction,and type of social interaction,with OR (95％CI) at 1.69(1.002.87) / 1.72(1.022.90).Conclusions Loneliness is a significant and independent impact factor for cognitive dysfunction among community dwelling elders.

ABSTRACT
Objective To explore the situation of return-to-work (RTW) and its related factors in female injured works. Methods The da-ta of the basic information, counseling record and follow-up record after discharge were collected from social rehabilitation department in our center. The main influencing factors were analyzed by single factor analysis and two classification Logistic regression. Results 232 ob-jects were collected, among which, 149(64.2%) subjects had returned to work, and the median of absence time was 206.5 days. Single factor analysis indicated that their age, marriage, absence time and educational level were not correlated with the outcome of women injured work-ers' employment (P>0.05). However, place of social insurance, household register and injury severity correlated with the outcome (P<0.05). Conclusion Most of the female injured workers can return to work. The severity of injury, along with some system factors influence the RTW of them.
ABSTRACT
Objective To investigate the relationship between maximum blood pressure and the prognosis after discharged from the hospital,among patients with ischemic stroke.Methods A cohort study was conducted which including 471 cases of ischemic stroke patients that were collected from February 2014 to December 2014 at the Second Affiliated Hospital of Harbin Medical University.Values of everyday blood pressure were measured on each patient at the first six days after admitted to the hospital.Maximum blood pressure value of the 6 days was taken as an indicator of the blood pressure levels.The ability on daily living was measured by the modified Rankin score (mRs).Data were analyzed by Chi-square test,t test and multivariate logistic regression analysis.Results Confounding factors would include age,gender,culture,physical activity,income,smoking,alcohol,hypertension,diabetes,coronary heart disease,stroke history,hospitalization mrs,lipid parameters,homocysteine and blood sugar and were adjusted.Results from multivariate logistic regression analysis showed that the maximum SBP was associated with adverse outcomes.Compared with 140-159 mmHg for SBP,OR(95％CI) was 2.51 (1.30-4.85) for 160-179 mmHg,OR (95％ CI) was 2.68 (1.27-5.65) for those pressure levels higher than 180 mmHg,after multiple factors were adjusted.Compared with 90-99 mmHg for DBP,OR(95％CI) was 1.92 (1.00-3.67) for 100-109 mmHg,OR (95％ CI) was 2.78 (1.35-5.69) for the ones higher than 110 mmHg.Conclusion Maximum blood pressure during hospitalization might be associated with adverse outcome of ischemic stroke patients.
ABSTRACT
<p><b>OBJECTIVE</b>Dehydroandrographolide (DP) from Andrographis paniculata (Burm. F.) Nees is a potential anticancer agent. This study aimed to investigate the oral bioavailability and intestinal disposition of DP to provide useful information for the development of DP as a new candidate anticancer drug.</p><p><b>METHODS</b>The pharmacokinetics of DP was evaluated in rats, and its intestinal disposition was determined using cultured Caco-2 cells and a single-pass rat intestinal perfusion model.</p><p><b>RESULTS</b>The oral bioavailability of DP was 11.92% in rats. The apparent permeability coefficient (P(app)) of DP from the basolateral side (B) to the apical side (A) (5.37×10(-5) cm/s) of the Caco-2 model was roughly equal to that from A to B (4.56×10(-5) cm/s), suggesting no involvement of the efflux transporter(s). In the perfusion model, no significant difference was found in the effective permeability (P*(eff)) of DP between the 4 segments of the intestine. No significant metabolism of DP was detected in the intestinal perfusates. The amount of DP found in the bile was only about 0.1% of the absorbed amount. The P*(eff) and bile amounts of DP were not significantly increased by P-glycoprotein (P-gp) inhibitor or breast cancer resistant protein (BCRP) inhibitor (P>0.05).</p><p><b>CONCLUSION</b>The bioavailability of DP was 11.92% in rats. DP has good absorption and metabolism stability in the intestine. The efflux transporters such as P-gp and BCRP do not participate in DP transport.</p>

@#Objective To explore the case management model of return to work injured workers. Methods A retrospective cohort wasformed with 523 injured workers in rehabilitation centre. The social demographic information, medical data and intervention process wereextracted from the medical records. A Cox Regression Model was used to examine the effect of case management on work processes and otherrelevant factors affecting RTW. Results 275 cases (82.1%) out of the 335 subjects successfully returned to work after median absence durationof 36.0 days. Computer training prompted RTW outcomes (P<0.01), while disability adjustment activity showed an opposite effect(P<0.05). It showed that education level, family attitude to RTW and level of injury were significantly associated with outcomes of RTW.Conclusion Specific skills reconstruction and training would is one of the most important components of the case management interventionprogram on RTW. Although disability adjustment did not specifically benefit RTW, it might help in improving workers' general health status,and it should not be ignored in any case.
