PURPOSE: This study was to investigate depression in Korean-Chinese elder living in the Yanbian Korean Autonomous Prefecture in China. METHODS: A cross-sectional community-based survey was conducted using face to face private interviews for elders aged over 59, who have been dwelling in the Yanbian Korean Autonomous Prefecture. The samples consisted of 183 Korean-Chinese and 182 Han-Chinese with the latter as a reference group. Data were collected from August 25 to September 20, 2011 and analyzed with the SPSS 18.0 program. The GDS (Geriatric Depression Scale) was used to measure elderly depression in the subjects. RESULTS: In Korean-Chinese, the rate of depression was higher in those who had lower educational levels, and were economically supported by the government. And those who had depression showed lower scores in Chinese language proficiency, health status, and social supports, and had more chronic diseases. Factors having effects on Korean-Chinese elderly depression included perceived health status and subjective support. CONCLUSION: According to the results, for preventing the depression of Korean-Chinese, it is necessary to develop health management programs and social support networks, which were easy to approach.

Objective:To observe the clinical efficacy of combined acupuncture and psychological desensitization therapy for anxiety in those with heroin addiction.Methods:All 90 cases were randomly allocated into a treatment group (45 cases) and a control group (45 cases).Cases in the treatment group received 30 min of combined acupuncture and psychological desensitization therapy for each treatment,twice a week and 8 weeks in total,whereas cases in the control group received no treatment.After that,the anxiety score and state were observed.In addition,the mental state prior to and after cue-elicited heroin craving was evaluated.Results:The total and standard scores of anxiety in the treatment group were significantly reduced compared to the control group (P＜0.05),coupled with a significant reduction of heroin craving (P＜0.01).Conclusion:Combined acupuncture and psychological desensitization can alleviate anxiety and inhibit the short-term heroin craving.

Objective To explore the effect of carvedilol on ACE2 gene and protein expression in chronic heart failure rats after myocardial infarction.Methods The heart failure model was induced by acute myocardial infarc- tion (AMI) through ligating the left anterior descending coronary artery.One month after operation,rats were randomized to receive placebo or carvedilol 2 mg/(kg?d),by gavage.Sham-operated rats were used as the control group.Hemodynamies,body mass and left ventrieular mass index,plasma and myocardial level of angiotensin Ⅱ were determined.ACE2 gene and protein expression was assessed by using RT-PCR and Western Blot.Results The mortality of placebo and Carvedilol groups were 20%,compared with 0% in sham operated rats.Carvedilol significantly improved LVEDP,LVSP,+dp/dt_(max) and-dp/dt_(min) in CHF rats but all the hemodynamics data were still inferior than that of controls.Plasma and myocardial angiotensin Ⅱ level were increased significantly in CHF placebo rats than those of control rats (plasma Ang Ⅱ:CHF:194?19 vs controls:132?15 ng/L,myocardium Ang Ⅱ:CHF:6.7?0.4 vs control:3.8?0.3 ng/g,P

BACKGROUND AND PURPOSE: The purposes of this study were to standardize and validate a Korean version of the Insomnia Severity Index (ISI-K), and to evaluate its clinical usefulness. METHODS: We translated the ISI into Korean and then translated it back into English to check its accuracy. The 614 patients with sleep disorders who were enrolled in this study comprised 169 with primary insomnia, 133 with comorbid insomnia, and 312 with obstructive sleep apnea. All subjects underwent one night of polysomnography (PSG) and completed the Korean versions of both the Pittsburgh Sleep Quality Index (PSQI-K) and the Epworth Sleepiness Scale, as well as the ISI-K. The ISI-K was compared to these sleep scales and various PSG sleep parameters. RESULTS: The internal consistency the ISI-K total score was confirmed by a Cronbach's alpha of 0.92, and the item-to-total-score correlations (item-total correlations) ranged from 0.65 to 0.84, suggesting adequate reliability. The correlation between the ISI-K total score and PSQI-K was 0.84, which suggested adequate convergent validity. Low-to-moderate correlations were obtained between the ISI-K total score and PSG-defined sleep parameters: 0.22 for sleep onset latency, 0.38 for wake after sleep onset, and 0.46 for sleep efficiency. A cutoff score of 15.5 on the ISI-K was optimal for discriminating patients with insomnia. The test-retest scores over a 4-week interval with 34 subjects yielded a correlation coefficient of 0.86, suggesting excellent temporal stability. CONCLUSIONS: The findings of this study show that the ISI-K is a reliable and valid instrument for assessing the severity of insomnia in a Korean population.

OBJECTIVETo compare the efficacy of different points combination in the treatment of menopausal insomnia.

METHODSNinety-six cases of menopausal insomnia were randomized into 3 groups, Xinshu (BL 15), Shenshu (BL 23), Sishencong (EX-HN 1), Shenmen (HT 7), Sanyinjiao (SP 6) were chosen in the restore interaction between the heart and the kidney group (group A, 32 cases); Zhaohai (KI 6), Jiaoxin (KI 8), Shenmai (BL 62), Pucan (BL 61) were chosen in the acupuncturing qiao mai group (group B, 32 cases); auricular Shenmen (TF4) and sensitive spot at the distribution area of auricular vagus nervus were chosen in the ear acupuncture group (group C, 32 cases). Six days made one session and the treatments were finished after 4 courses. The polysomnography (PSG) and Pittsburgh sleep quality index (PSQI) were employed before and after treatment to evaluate the alleviation of insomnia.

RESULTSThe parameters of the sleep latency (SL), rapid wave sleep latency (RL) and sleep efficiency (SE) were significantly improved in the three groups, and the differences were statistically significant (P < 0.05, P < 0.01). The SL and awaking time (AT) in group C [SL (401.08 +/- 16.54) min and AT (4.87 +/- 2.64) times] were significantly superior to those in the other two groups [SL (50.36 +/- 18.47) min, (54.87 +/- 20.92) min, AT (5.98 +/- 2.11) times, (6.13 +/- 3.04) times, all P < 0.05]. The S(3+4) (%) in group C was also significantly higher than those in the other two groups (both P < 0.05). It was indicated by PSQI that the sleep quality of group C (0.78 +/- 0.12) was significantly superior to that in group B (1.32 +/- 0.29), the total score and cured and markedly effective rate in group C [(4.34 +/- 1.43), 68.8% (22/32)] were superior to those in group A [(7.48 +/- 3.09), 53.1% (17/32), both P < 0.05].

CONCLUSIONEar acupuncture has a better curative effect than the restore interaction between the heart and the kidney group and acupuncturing qiao mai group, it is worth of being promoted.

Objective To analyze obese children serum lipid level in order to understand the relationship between serum lipid and cardiovascular disease in obese children.Methods One hundred and fifty-three children(109 male and 44 female)aged 4-16 years old with obesity who attended the outpatient clinic of Beijing Children′s Hospital were collected.Percentage body fat (%BF),body fat (BF),fat-free mass (FFM) was estimated by using bioelectrical impedance analysis (BIA) and calculate.Waist and hip circumference,waist-to-hip ratio (WHR) was estimated by soft tape measure and calculate.Skinfold thickness of scapular bone below (S) and triceps muscle (T),S/T rate was estimated by skin fold meter and calculate.Serum total cholesterol (TC),triglyceride(TG),high density lipoprotein(HDL-C),low density lipoprotein(LDL-C),apolipoprotein(Apo) AI and Apo B levels were also measured.SPSS 11.0 software was used to analyzed the data.Results The cardiovascular disease related was the prevalence of high TC levels(3.3%)or high LDL-C level(6.0%) and high TG level(24.7%) was rather low.HDL-C level was reduced in 31.3% of obese children.In children over 10 years old,%BW and %BF showed a weak correlation with HDL-C(r=-0.202,-0.211).Conclusions In obese children,serum lipid as well as Apo level should be exa-mined in order to evaluate angiocardiopathy.

Objective:To investigate characteristic expression of TGF-?1 in human ADPKD and clarify its role in the development and progression of human ADPKD. Methods:Cyst fluid, urinary and plasma TGF-?1 levels were determined by ELISA in 39 ADPKD patients. The results were compared with those of normal subjects and of patients with simple renal cyst. TGF-?1, TGF-?1 receptors types Ⅰ, types Ⅱ, CTGF mRNA and proteins in the kidneys of human ADPKD were examined by in situ hybridization and immunohistochemistry. The relationship of the above fibrosing-associated indicators with the degree of interstitial fibrosis was analyzed. Results:Plasma TGF-?1 level was the highest among body fluids. In ADPKD and simple renal cyst, TGF-?1 levels were significantly higher than those in normal subjects (15.12 ?8.53)?g/L vs (5.41?1.31) ?g/L,P

Objective To assess and compare the peri-implant stress distribution of three posterior implants under immediate loading with 4 different bone qualities using three dimensional (3D) finite element (FE) analysis. Methods A 3D finite element model representing three implants in a portion of mandible at the 654-| region was developed, and three implants received a crown each. Four types of bone qualities (B1,B2, B3 and B4) were designed for the model. Load of 100 N was applied on the occlusal surfaces of the crowns at a 45° angle to the vertical axis of the implants. Results Von Mises stresses in the peri-implant bone of4-| in bone quality from B1 to B4 were ( 13. 17 ± 9. 32), ( 12. 95 ± 9. 14), ( 15. 00 ± 9. 44 ), and(16.81 ±10.74) MPa, and those of 5-| were (15.51 ± 10.32), (14.73 ±8.96), (16.79 ±8.40), and(18. 34 ±8.45) MPa. Stress in bone quality B4 showed the highest value, followed by B3 bone, the loweststress were found in B1 and B2 bone. It was significantly different (P ＜0. 05). However, von Mises stresses in different quality of bone around 6-| [(42.45 ±25.71), (41.66 ±25.29), (42.70 ±23.24), (42.06 ±23.66) MPa] were close to each other, and were as twice or three times as those of 4-| and 5-| , irrespective of different bone qualities. Conclusions The stress distribution around implant under immediate loading was not only affected by different bone qualities, but also by the direction of loading, and the latter may have a greater impact when a severe load delivered.
