OBJECTIVETo observe the regulatory effects of electroacupuncture with different acupoints combinations on blood lipid and atherosclerosis index (AI) in rats with hyperlipemia, so as to make a preliminary screening for the optimal acupoints combination for hyperlipemia.

METHODSOne hundred and five clean-grade SD male rats were randomly divided into 9 groups, including a normal group, a model group, a Quchi group, a Zhongwan group, a Fenglong group, a Quchi+Zhongwan group, a Quchi+Fenglong group, a Zhongwan+Fenglong group and a Quchi+Zhongwan+Fenglong group (three acupoints group), 17 rats in the normal group and 11 rats in the rest groups. The normal group was fed with normal diet, while the rest groups were fed with high-fat diet for 3 weeks to prepare the hyperlipemia model. All the rats were given unlimited water. After the establishment of model, the normal group was fed freely without any treatment; the model group was bundled and immobilized everyday; the rest groups were bundled, immobilized and treated with electroacupuncture at corresponding acupoints with disperse-dense wave, 20 min per time, once a day. After 4 weeks, the blood examples were collected from abdominal aorta to measure the total cholesterol (TC), triglyceride (TG), high-density lipoprotein (HDL-C) and low-density lipoprotein (LDL-C), and analyzed the AI in each group.

RESULTSAfter the treatment, TC, TG, HDL-C, LDL-C and AI in each acupuncture group were all lower than those in the model group (P<0.05, P<0.01). Compared with single acupoint group and the Quchi+Zhongwan group, the content of TC in the three acupoints group was lower (P<0.01). The differences of content of TG among each acupuncture group were not significant (all P>0.05). Compared with the rest 6 acupuncture groups, the content of HDL-C and AI in the three acupoints group were significantly different (all P<0.05). The content of LDL-C in the three acupoints group was decreased as compared with the Quchi group and the Zhong-wan group.

CONCLUSIONThe electroacupuncture at "Quchi" (LI 11), "Zhongwan" (CV 12) and "Fenglong" (ST 40) has more advantages on regulating the content of HDL-C and LDL-C as well as improving AI in hyperlipemia rats, and it has superior effects on blood lipid metabolism.

Objective To study the relationships among resilience, self-awareness, personality, stress level and mental health in the warship soldiers. Methods Resilience Scale for Adults ( RSA), Eysenck Personality Questionnaire ( EPQ), Self Acceptance Questionnaire( SAQ), General Self-Efficacy Scale( GSES), Wallance Self Concept Scale (WSCS), Psychological Stress Self-evaluation Test (PSET) and Symptom Checklist (SCL-90)were used to survey 1451 warship soldiers. Results ① 2.5％ of the warship soldiers reported obvious psychological stress. Mental health of warship soldiers was worse than the norm of China population, except for obsessivecompulsive and interpersonal sensitivity factor. While the scores of other factors were significantly higher than the norm of Chinese soldiers(P＜0.01). ②The total scores of SCL-90, psychological stress and resilience, internal/external had negative correlation with self-awareness, and positive correlation with neuroticism. Compared to the SCL-90-negative group,SCL-90-positive soldiers (SCL-90 total score ＞ 160) had higher scores of nervousness and PSET and lower scores of RSA, internal/external and self-awareness (P ＜ 0.01 ). ③Regression analysis showed that stress levels, emotional stability,self-awareness and resilience were able to predict 35.1％ of mental health in warship soldiers. Mental health, emotional stability, internal/external and resilience were able to predict 33.2％of individual's stress level. Conclusion To some extent, warship soldiers have psychological stress and mental health problems. Resilience, personality, self-awareness are important factors affecting psychological stress and mental health.

Objectlve To assess the clinical effects and safety of intravitreal injection of conbercept and macular photocoagulation for non-ischemic macular edema secondary to branch retinal vein occlusion (BRVO).Methods A total of 50 patients (50 eyes) with non-ischemic macular edema following BRVO were retrospectively analyzed.Patients were divided into 2 groups:ICI group (26 eyes) received intravitreal injection of conbercept,laser group (24 eyes) received standard-of-care grid laser for macular edema.The best-corrected visual acuity (BCVA) and central macular thickness (CMT) were observed before and 1 week,1 month,2 months and 3 months after treatment.Then,the changes in pre-treatment and post-treatment were compared,and the related complications were recorded.Results The difference of BCVA before treatment was not significant between two groups (P ＞ 0.05).BCVA at 1 week,1 month,2 months and 3 months after treatment in two groups were all improved,the differences were statistically significant compared with before treatment (all P ＜ 0.05),and the differences were statistically significant between two groups after treatment (all P ＜0.05).At 3 months after treatment,BCVA of 18 patients (69.23％) in ICI group and 8 patients (33.33％) in ICI group improved 2 lines.The difference of CMT before treatment was not significant between two groups (P ＞ 0.05),CMT at 1 week,1 month,2 months and 3 months after treatment in two groups were all decreased,the differences were statistically significant compared with before treatment (all P ＜ 0.05),and the differences were statistically significant between two groups after treatment (all P ＜0.05).13 eyes received repeat intravitreal injection in ICI group,including 2 eyes at 1 month,7 eyes at 2 months with CMT ＞250 μm,and 3 eyes at 3 months.No severe side effect related with drug and intravitreal injection occurred in the two groups.Conclusion Mean BCVA change and CMT change are significantly greater in the intravitreal injection of conbercept than the standard-of-care grid laser group for the macuiar edema secondary to non-ischemic BRVO.

Objective To measure the concentration of serum transthyretin (TTR) of patients with different stages of diabetic retinopathy (DR).Methods A total of 176 patients with diabetes mellitus were included in this study.There were 104 males and 72 females.The patients aged from 21 to 74 years,with the mean age of(56± 11) years.The diabetes duration raged from 1 to 30 years,with the mean diabetes duration of (10 ± 7) years.The HbA 1C was 5.2％-14.1％,with the mean HbA 1C of (8.6 ± 2.0)％.According to the fundus examination,58 patients had DR (33.0％),but the other 118 patients not (67.0％).For these DR patients,10 patients were in stage Ⅰ (5.7％),26 patients in stage Ⅱ (14.8％),8 patients in stage Ⅲ (4.5％),and 14 patients in stage Ⅳ (8.0％).The concentration of serum TTR was measured by enzyme-linked immunosorbentassay kit.The differences in the concentration of serum TTR between different DR stages were compared.Bivariate analysis was used to analyze the influencing factors of TTR.Results The concentrations of serum TTR of the patients without DR or with DR of stage Ⅰ to Ⅳ were (224.96±65.47),(383.68± 102.99),(247.44±63.21),(228.2 ± 45.89),(189.34± 70.12) mg/L,respectively.The difference between different DR stages was statistically significant (F=14.690,P＜ 0.001).Bivariate analysis showed that the concentration of TTR was correlation to DR (r=0.179,P=0.017).There was no correlation between the concentration of TTR and diabetes duration (r=-0.027,P=0.727),hypertension (r=0.018,P=0.810),hyperlipoidemia (r=0.101,P=0.182),and the use of insulin (r=-0.032,P=0.675).Conclusion The concentration of serum TTR was increased in early DR patients,and gradually decreased with the progression of DR.The concentration of TTR is correlated to DR.

OBJECTIVE: To resolve the problem of the accuracy and standardization of STR-PCR typing in forensic practice, we have designed a new method to produce standard D1S549 allelic ladder. METHODS: Eight different PCR amplified D1S549 allelic fragments were isolated from the gel, eluted into the distilled water and re-amplified by PCR. The purified allelic fragments were then blunt-end subcloned individually into the pUC plasmid vectors and transfected into competent E. coli DH5 alpha cells. RESULTS: The sequencing results confirmed that the size and the construe of the inserts were correct. The recombinant plasmids DNA with 8 inserts were then used as templates for re-amplification to generate D1S549 standard ladder, with which the genetic polymorphisms of D1S549 locus in Chinese Han population in chengdu, Hui population in Gansu and Wei population in Xinjiang were studied. CONCLUSION The results showed that the standard ladder made via this method is excellent, and D1S549 locus is robust for genetic research and forensic application.

OBJECTIVETo investigate the sanitary status of urban secondary water supply facilities in Haidian district of Beijing.

METHODSAdopting the quantitative classification table drafted by the Bureau for Sanitation Inspection and Supervision of Haidian district, we carried quantitative classification (A, B, C grade) on all 1725 secondary water supply facilities in Haidian district for two times. At the same time, we collected 20 residential areas with stratified random sampling method. As the public points in the first quantitative classification, the effect of level publicity on changing the sanitary grade of the secondary water supply facilities were observed.

RESULTSIn the first two times of quantitative classification, A-level and B-level secondary water supply facilities took up 81.04% (1398/1725) and 89.04% (1536/1725) of all secondary water supply facilities respectively; the ratio of effective sanitary permits achieved 86.14% (1486/1725) and 92.35% (1593/1725) respectively; and the ratio of effective water quality test reports achieved 86.60% (1494/1725) and 97.10% (1675/1725) respectively. There were 52 secondary water supply facilities in 20 collected areas, including 8 A-level, 27 B-level and 17 C-level secondary water supply facilities before level publicity, and 19, 29 and 4 after level publicity. The impact of level publicity on changing the sanitary grade of the secondary water supply facilities was statistically significant (χ(2) = 12.60, P = 0.002).

CONCLUSIONThe city secondary water supply facilities in Haidian district are overall in good sanitary conditions. Quantitative classification and level publicity can effectively improve the sanitary status of secondary water supply facilities.
