Objective To investigate the prevalence rate of hypertension among the elderly population in Shanxi Province. Methods According to the random sampling, 41 residents committees of city blocks and villages of 9 areas (including Taiyuan, Datong, Jinzhong, Yuncheng, et al) of Shanxi Province were extracted as the investigative spots. All the people were older than 55years, and risk factors for hypertension were identified. Results A total of 3702 people were surveyed, including 1,782 men and 1,920 women. The total hypertension prevalence rate was 39.0%(the standardized rate: 39. 5 %), with 38. 7 % in men (the standardized rate: 38. 5%), 39.3 % in women (the standardized rate: 41.2%), and no statistic significance was found between men and women (χ2= 0. 143, P>0. 05). Aging, lacking of knowledge, and obesity were risk factors for hypertension. Conclusions The hypertension in Shanxi Province has a high prevalence rate among the elderly population, a comprehensive intervention should be taken in the prevention of hypertension.

Objective: To observe the clinical effect of traditional Chinese medicine on recurrent oral ulcer. Methods : 68 patients with recurrent oral ulcer were treated in our hospital, 68 outpatients were randomly divided into two groups: treatment group and control group. The control group received outpatient symptomatic treatment and uninterrupted given cydiodin, vitamin C and compound vitamin B tablets for oral treatment; treatment group were given outpatient treatment and traditional Chinese medicine ointment conditioning based on syndrome differentiation. To observe and compare clinical efficacy of the treatment group. Results : The total effective rate of the treatment group was 86.11%, which was significantly better than that of the control group 28.13%, the difference was statistically significant (P<0.01). Conclusion Traditional Chinese medicine ointment in the treatment of recurrent oral ulcer can significantly reduce recurrence rate, improve the immune function of the body, clinical efficacy, the quality of life of patients.

Objective To explore the current status of stress level and its influencing factors among patients in observation room of emergency department .Methods Totally 300 patients in the observation room of emergency department from September 2014 to September 2015 were recruited in this study by convenience sample method.General situation questionnaire and stress-reacton questionnaire ( SRQ) were used to conduct this cross-sectional survey .Results The scores of SRQ and body reaction factor were ( 56.25 ±20.20) and (19.41±7.87), and they were all significantly higher than the national norm (t=2.231, 6.034;P<0.05).The score of behavior reaction was (10.65±4.82), and it was lower than the national norm (t=-9.143, P<0.01). There was no significant difference between the score of emotional reaction and national norm ( P>0.05) .Single-factor analysis showed that , the differences in the score of emotional reaction among patients with different working situation and monthly income were significant (F=3.684,4.109,P<0.05).The differences in the score of body reaction among patients with different working situation , occupation , monthly income and religion were significant (F=4.851,3.624,2.678,5.033;P<0.05).The differences in the score of behavior reaction among patients with different working situation and occupation were significant (F=4.181,2.489;P<0.05).Multiple stepwise regression analysis showed that religious faith and monthly income were identified as significant influencing factors of stress level (P<0.05).Conclusions Medical personnel should guide patients to correctly face the stress based on their religious faith and monthly income , so as to promote the recovery of health .

Objective To explore the stress among patients in Emergency Observation Room and its correlation with coping modes.Methods A total of 300 patients in Emergency Observation Room of a Class Ⅲ grade A hospital were recruited by convenient sampling method for a cross-sectional survey and its correlation, from September 2014 to September 2015, using the general situation questionnaire, stress-reaction questionnaire (SRQ) and medical coping modes questionnaire (MCMQ). The data of survey was compared with norm, and Pearson correlation analysis was used to analyze the correlation between stress reaction and medical response level.Results The score of stress reaction was (56.25±20.20), in which somatic reaction was (19.41±7.87), higher than norm of hospitalized patients and the behavior reaction was (10.65±4.82),lower than the norm of hospitalized patients (t=6.034, -9.143;P<0.01). The total score of coping style of patients in emergency observation room was (39.26±6.97), in which the face dimension was (17.63±3.90), avoidance (13.96±3.28), yield (7.66±2.66), all lower than the norm of hospitalized patients (t=-8.200,-2.514,-7.485;P<0.05). The correlation was positive between stress reaction and coping styles (r=0.125-0.510,P<0.05). Conclusions The stress has close correlation with coping style for patients in Emergency Observation Room. Medical personnel should guide emergency patients to correctly face stress, and improve their coping styles.

Objective:To investigate the clinical significance of suction blister transplantation in improving the efficacy of ReCell technique in the treatment of vitiligo.Methods:Patients were divided into three groups, namely, vitiligo patients without history of suction blister therapy, patients with ineffective suction blister therapy and patients with effective suction blister therapy. There were 30 patients in each group. All patients were treated with standard procedure of ReCell technique. The color recovery effect of leukoplakia was observed 3 and 6 months after operation, and the incidence of complications was also observed.Results:The effective rate of color recovery 3 and 6 months after operation were as follow: in patients without history of suction blister group, the effective rate of three months was 53.3%, and that of six months was 63.3%; in patients with ineffective suction blister group, the effective rate was 43.3% in three months and 50.0% in six months, and in patients with effective suction blister group, the effective rate was 76.7% in three months and 90.0% in six months. No obvious complications were observed in the three groups.Conclusions:For the treatment of stable vitiligo with ReCell technique, suction blister method is a simple and effective method for screening patients.

Objective: To analyze the association between polycyclic aromatic hydrocarbons(PAHs)exposure and rheumatoid arthritis(RA)based on large sample data. Methods: The RA patients(RA group)and non-RA patients(non-RA group)with complete data were selected from the National Health and Nutrition Survey Database in the United States(NHANES)(2005—2014). The logistic regression model was used to analyze the association between 8 monohydroxylated(OH-)PAH metabolites in the urine and RA. Results: A total of 357 RA patients and 5, 256 non-RA participants were included.After adjusting the confounding factors by logistic analysis, the level of OH-PAHs mixture at the highest quartile(Q4)was associated with increased risk of RA compared with that at the lowest quartile(Q1)(OR=1.60, 95%CI: 1.16-2.23). For a single kind of OH-PAHs, the Q4 levels of 1-hydroxynaphthalene(OR=1.59, 95%CI: 1.14-2.23), 2-hydroxynaphthalene(OR=1.66, 95%CI: 1.19-2.32), 2-hydroxyfluorene(OR=1.61, 95%CI: 1.17-2.22), 3-hydroxyfluorene(OR=1.64, 95%CI: 1.18-2.27)and 1-hydroxyphenanthrene(OR=1.38, 95%CI: 1.00-1.94)were all associated with significantly increased risk of RA compared with the Q1 level(all P<0.05). However, the Q2 level of 1-hydroxypyrene(OR=0.60, 95%CI: 0.43-0.83)was related to a decreased incidence of RA(P<0.01). Conclusions OH-PAHs mixed exposure is a risk factor for RA.The association between the level of individual OH-PAH and the rate of RA is bidirectional and is depended on the type and concentration of OH-PAHs.
