Objective:To examine the relationships between acute stress disorder (ASD) symptoms,posttraumatic stress disorder (PTSD) symptoms and depressive symptoms in children survivors following the Lushan earthquake in China.Methods:One hundred ninety-seven children aged 1 to 14years (93 male and 104 female) were followed up at two and six weeks after Lushan earthquake.The ASDS,UCLA PTSD Reaction Index and DASS were used to measure the ASD,PTSD and depressive symptoms.Results:The average scores of ASDS and the depression subscale of DASS at two weeks after earthquake were(36.5 ± 10.9) and (3.3 ± 2.8),respectively.The average scores of UCLA PTSD Reaction Index and the depression subscale of DASS-21 at six weeks after earthquake were (18.5 ± 12.6) and (3.3 ± 3.5),respectively.The rates of ASD and PTSD were 28.6％ and 8.2％,respectively.The cross-lagged structural equation analysis with latent variables indicated that the ASD symptoms at two weeks after earthquake positively predicted PTSD symptoms (β =0.59,p ＜ 0.001) and depressive symptoms (β =0.29,p ＜0.001) at six weeks after earthquake.But there was no significant association between depressive symptoms at two weeks and PTSD symptoms at six weeks after earthquake.Conclusion:ASD symptoms in the early time postearthquake could predict subsequent PTSD and depressive symptoms,while depressive symptoms tend to remain stable within six weeks after earthquake.

Objective:To determine the change in the dietary patterns of Hunan urban residents from1982 to 2012. Methods:A 24 hour dietary recall method was used for 3 consecutive days to collect information on food intake, and the condiment intake was collected by weighting method. Results:Rice products and potato consumption were 449.0 g per person per day and 44.0 g per person per day in 1982, and dropped to 150.0 g per person per day and 9.0 g per person per day in 2012. In 2012, vegetable (277.1 g per person per day), fruits (47.8 g per person per day), milk and dairy products (16.6 g per person per day) consumption were still insuffcient. Fat (59.3 g per person per day) and salt (10.1 g per person per day) consumption was still high. Conlusions:hTe dietary quality of urban residents in Hunan has been greatly improved, but is still seriously imbalanced. To consume more fruits, milk and dairy products and reduce fat and salt intake are very important.

Objective To investigate the relationship between blood concentration of sodium valproate and the anti‐epileptic effect and the influencing factors of blood concentration of sodium valproate ,and to provide evidence for clinical individual adminis‐tration .Methods The blood concentrations of 133 cases of patients treated with sodium valproate were determined in the affiliated Yongchuan hospital of Chongqing medical university ,the monitoring results of blood concentration were statistically analyzed ,and the anti‐epileptic effect of 133 cases of patients were observed and analyzed .Results The epilepsy of 80 cases of patients were con‐trolled ,accounted for 60 .15% of the total number;in the 69 cases of patients within the effective blood drug concentration (50-100 mg/L) ,the epilepsy of 51 cases of patients were controlled ,accounting for 38 .35% .In the 44 cases of patients whose blood drug concentration were less than 50mg/L ,the epilepsy of 26 cases of patients were not controlled .The distribution of blood concentra‐tion between men and women were similar .The blood concentrations among each age group were different ,the blood concentrations of 52 .87% patients in the adult group were below or above therapeutic range that were 39 .13% in the minor group .The adverse reactions were increase with the increase of blood concentration .Conclusion There are differences between the blood concentrations of sodium valproate and clinical effect ,the reasonable individual administration should be conducted according to the patient′s blood concentrations of sodium valproate ,the epilepsy control situation of patients and the patients′age .

Multilevel models are applicable to both the quantitative data and categorical variables. We used the methods, including the multilevel models, analysis of covariance and CMH chi-square test, to analyse different types of data, to explore the application of multilevel models in the analysis of the multicenter clinical trial center effect. The results showed that the analysis of covariance is more sensitive to find the center effect for quantitative data, while multilevel models are more sensitive to categorical variables. It can be seen that results with different analytical methods for center effect are not the same, and the most appropriate method should be selected in accordance with the characteristics of data, the objective of research, and the applicable conditions of the various methods in practical use.

Objective To explore the possible correlation between periodontal disease and carotid arteries atherosclerosis in old people,and to study the diagnostic value for periodontal disease using three-dimensional (3D) reconstruction technique of multi-slice spiral CT (MSCT).Methods Patients underwent multi-detector row CT angiography with carotid arteries atherosclerosis (control group) and without carotid arteries atherosclerosis (case group) were evaluated with the stereoscopic configuration of teeth,and the number of decayed teeth and lost teeth were recorded.Results Bythe 3D reconstruction technique,the number of decayed teeth and lost teeth between two groups were significantly different (P＜0.05).The number of dental integrity patients was higher in control group (19 cases) than in case group(7 cases).The mean of dental caries was higher in control group(7.3±3.0) than in case group(6.0±2.1).The mean of hypodontia was higher in control group(45 cases) than in case group(39 cases) (P＜0.05).Conclusions The 3D reconstruction technique of MSCT is a new method to display the stereoscopic configuration of teeth.The periodontal disease is significantly related with carotid arteries atherosclerosis in old people.

Objective:To observe the clinical effect of acupuncture combined with low-frequency electric stimulation on scissor gait in children with spastic cerebral palsy. Methods:A total of 60 spastic cerebral palsy kids were allocated into two groups by random number table, 30 in each group. Cases in the control group were treated with physical exercise therapy, massage and hydrotherapy. Based on the therapies given to the control group, cases in the observation group were supplemented with acupuncture combined with low-frequency electric stimulation. Selected points included Zusanli (ST 36), Sanyinjiao (SP 6), Yanglingquan (GB 34), Jiexi (ST 41), Chengshan (BL 57), Naoqing [Extra, locates at 2 cun directly above Jiexi (ST 41)] and Genping (Extra, locates at the midpoint of the line connecting medial and lateral malleolus). The treatment was done once every other day and 10 d made up a treatment course. The low-frequency electric stimulation was applied to anterior tibia, 6 times a week and 20 times made up a treatment course. Cases were treated for a total of 3 courses and there was a 15-20 d interval between two courses. The low limb functions were assessed before and after treatment using the modified Ashworth scale (MAS) and composite spasticity scale (CSS). In addition, the ankle dorsiflexion angles were measured before and after treatment. Results:After treatment, the ankle dorsiflexion angles and CSS scores in the observation group were better than those in the control group, showing statistical significances (P<0.05); the effective rate in the observation group calculated by MAS and ankle dorsiflexion angle were both higher than that in the control group, showing a statistical significance (P<0.05). Conclusion:Rehabilitation training combined with acupuncture and low-frequency electric stimulation can achieve better effect than rehabilitation training alone in improving scissor gait in kids with spastic cerebral palsy.
