Methods: Th e cDNA of truncated BMP-II receptor was transfected into Tca8113 cells by usin g FuGENE6 transfection kit, the transfected cells were named Tca8113ZR. The pro liferation and DNA synthesis of Tca8113 and Tca8113ZR cells were investigated b y MTT assay,FCM and BrdU analysis. Results: In MTT assay the A value of Tca8113 and Tca8113ZR cells was 0.47?0.01 and 0.35?0.01 (P0.05).Conclus ion: BMPs might be involved in the development of squamous cell carc inoma of tongue.

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 investigate the epidemic situat ion of the dental fluorosis among the people in Tianjin area.Methods　With the method of random sampling we investigated epidemic situation of the dental fluorosis among the people aged 12 to 15 in Tianjin area.Results　The minimum patient's rate for this disease among those aged 12 to 15 is 32.11 percent while the maximum is 78.09 percent.The l owest dental fluorosis index is 0.851 and the highest is 1.923.The patient's rate and the index are both higher than the average rate and index of the whole cou ntry.Conclusions　Tianjin is one of the areas where the dental fluorosise epidemic mostly occurs.

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 .

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 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 investigate the distribution and resistance of fungi isolated from hemopathy patients,and to provide the laboratorial data in order to prevent and treat infection caused by fungi more effectively.METHODS Strains were isolated from the upper respiratory tract,lower respiratory tract,genitourinary tract,alimentary tract;and perianal region,perineum,and the soft tissue and skin wounds.Antimicrobial susceptibility of clinical isolates was tested by broth microdilution susceptibility test.RESULTS Candida albicans,Aspergillus,tropicalis,C.krusei,and C.glabrata were the main fungi of total 3104 detected isolates.The resistance rates of C.albicans and C.tropicalis to fluconazole,itraconazole and 5-flucytosine were no more than 1.4%.The MIC50-MIC90 range of C.tropicalis for itraconazole was narrow(0.25-0.5 mg/L),but that was wide for fluconazole(0.25-4.0 mg/L).CONCLUSIONS C.albicans,Aspergillus,C.tropicalis,C.krusei,and C.glabrata are possibly the most common pathogens causing endogenous and exogenous fungi infection.The main infection sites of Aspergillus are the upper respiratory tract and lower respiratory tract,which may be associated possibly with ward's air quality.The MIC50to MIC90 range of C.tropicalis is wider for fluconazole than for itraconazole,which is possibly correlated with overexpression of CtMDR1 in C.tropicalis caused by the widely application of fluconazole in therapy.
