Objective:To compare clinical characteristics,treatment patterns and physiological indicators in bipolar disorder(BD)patients with different age of onset.Methods:Totally 380 patients with DSM-5 BD were se-lected in this study.Psychiatrists diagnosed the patients using the Mini International Neuropsychiatric Interview.The clinical information questionnaire and the Global Assessment of Functioning scale were utilized to collected clinical characteristics,treatment status,and physiological indicators.The onset age of BD was divided into 21 and 35 years as cut-off points.Multivariate logistic regression and linear regression were used to analyze related factors.Results:Among the 380 patients with BD,199 cases were early-onset group(52.4％),121 cases were middle-onset group(31.8％),and 60 cases were late-onset group(15.8％).There were 26.6％of patients in the early-onset group in-itially diagnosed as depression,23.1％in the middle-onset group,and 11.7％in the late-onset group.Multivariate analysis revealed that compared to the early-onset group of BD,the middle-onset(OR=2.22)and late-onset(OR=4.99)groups had more risk to experience depressive episodes,and the late-onset group(OR=6.74)had 6.74 times of risk to suffer from bipolar Ⅱ disorder.Additionally,patients in the middle-onset(β=-1.52)and late-on-set(β=-4.29)groups had shorter durations of delayed treatment,and those in the middle-onset(β=-1.62)and late-onset(β=-3.14)groups had fewer hospitalizations.Uric acid levels were lower in both the middle-onset(β=-28.39)and late-onset(β=-31.47)groups,and total cholesterol level was lower in the middle-onset group(β=-0.23).Conclusion:Patients with BD in different age of onset show significant differences in clinical charac-teristics,treatment conditions and physiological indicators.

Objective:To evaluate the anxiety and depression symptoms of burning mouth syndrome (BMS), and to explore risk factors to BMS.Method:In this case-control study,147 patients with BMS and 140 sex-and age-matched healthy volunteers were recruited.Three questionnaires were used to collect information of psychical and mental condition.The Self-Rating Anxiety Scale (SAS)and Self-Rating Depression Scale (SDS)were applied to evaluate symptoms of anxiety and depression.The scores of SAS and SDS were statistically analyzed by t-test.The risk factors of BMS were statistically analyzed by Chi-square test and logistic regression analysis.Result:The scores of SAS and SDS were higher in the patients with BMS than in the controls [SAS:(44.4 ±9.9)vs. (35.7 ±6.2);SDS:(48.1 ±11.6)vs.(37.5 ±8.9)].The risk factors of BMS included ischemic stroke (OR =4.46,95%CI:1.87 -10.95),low level of education (OR =1.91,95%CI:1.04 -3.49),anxiety symptom (OR =8.12,95%CI:2.60 -25.37)and depression symptom (OR =2.57,95%CI:1.26 -5.27).Conclusion:BMS is a multi-factorial disease.It indicates that ischemic stroke,lower level of education,anxiety symptom and depression symptom are the risk factors of BMS.A positive association could be established between psychological alterations and BMS.According to these findings it can be assumed that mental factors should be taking into account in the etiologyof BMS.It should be advocated to treat BMS patients by psychotherapy.

Objective:To describe the epidemiological characteristics of mental disorders in Ximeng Wa Au-tonomous County and explore psychosocial risk factors of mental disorders. Methods:Two thousand three hundred and eighty one residents aged 1 8 years and over were sampled using multistage sampling in Ximeng Wa Autono-mous County in 2013. All respondents were investigated by face-to-face interview. Mental disorders were screened out by using the General Health Questionnaire (GHQ)and diagnosed according to the International Classification of Diseases Checklist (ICD-10-Checklist)criteria. Results:Life time prevalence of any mental disorder was 19. 86%(419/2110). The lifetime prevalence rates of substance use disorder,anxiety disorder,insomnia,mood disorder, schizophrenia were 12. 99%(274/2110),6. 30%(133/2110),2. 94%(62/2110),2. 32%(49/2110)and 1. 00%(21/2110)respectively. Male (OR=0. 43),older age (35 -49 years,OR=1. 78;50 -64 years,OR=2. 59;≥65 years,OR=3. 5 1 ),unmarried and other marital status (OR=0. 3 1 ),non-Wa and non-Lahu ethnic groups (OR=0. 29)were associated with neurotic,stress-related and somatoform disorders. Male (OR=2. 41),older age (35 -49 years,OR=2. 29;50-64 years,OR=3. 20;≥65 years,OR=4. 58),non-farmer and non-self-employed occupation (OR=0. 41),and non-Wa and non-Lahu ethnic groups (OR=0. 32)were associated with psychoactive substance use disorder. Male (OR =0. 35 ) and order age (≥65 years,OR =3. 05 ) were associated with mood disorders. Conclusion:Lifetime prevalence of any mental disorder,substance use disorders and anxiety disorders are high in Ximeng Wa Autonomous County. Measures should be strengthened against prevalence of mental disorders in ethnic minority areas.

OBJECTIVETo evaluate the oral health-related quality of life (OHRQOL) in type 2 diabetic patients with chronic periodontitis.

METHODSA total of 80 type 2 diabetic patients with chronic periodontitis who had at least 16 teeth and never accept any periodontal therapy in latest one year were recruited. The clinical periodontal index such as probing depth, attachment loss (AL), modified bleeding index, plaque index were obtained with a Williams type periodontal probe. All accepted structured questionnaire interview including the evaluation of OHRQOL.

RESULTSThe geriatric oral health assessment index (GOHAI) results demonstrated good content validity, construct validity and responsibility. The periodontal index had positive correlation with the GOHAI scores. Individuals with self-unsatisfied of oral health status, using hypoglycemic drugs, accompanied with serious gingival inflammation and higher AL had relatively poor OHRQOL.

CONCLUSIONThe OHRQOL of type 2 diabetes with chronic periodontitis and the negative experiences of items listed in GOHAI questionnaire were affected by self-conscious of oral health and periodontal inflammation status.

OBJECTIVETo evaluate the effects of local-delivery of 25% metronidazol gel and mechanical cleaning using ultrasonic carbon fiber tip on dental implants with peri-implantitis.

METHODS27 implants with peri-implantitis were randomly assigned to receiving either 25% metronidazol gel treatment or carbon fiber tip ultrasonic scaling. All parameters including plaque index (PLI), probing depth (PD) of pocket, sulcular bleeding index (SBI), and BANA enzyme analysis were measured at baseline, 1, 2, 6 and 12 weeks after treatment.

RESULTSStatistically significant decrease (P < 0.05) in SBI, BANA test and PLI occurred in both treatment groups at all time intervals compared to baseline. PD had a decreasing tendency in both groups, but only metronidazole group reached statistically significant level (P < 0.05) at 2 and 6 week intervals compared to baseline. None of the treatment modalities produced any side effects on the implant and peri-implant tissues.

CONCLUSIONSBoth 25% metronidazol gel and mechanical cleaning using ultrasonic carbon fiber tip can be safely and effectively used in the treatment of peri-implant diseases.

OBJECTIVETo assess the relationship between oral malodor, volatile sulphur compounds (VSCs) levels in the mouth air and periodontal index; the role of tongue in the production of VSCs and halitosis.

METHODS60 periodontitis patients with oral malodor were included. Oral malodor was estimated by organoleptic method (organoleptic rating, OR); VSCs level measurements before and after cleaning the tongue coating were made with a portable sulphide monitor (halimeter), respectively; periodontal probing depth (PD) and the proportion of PD >/= 4 mm sites, bleeding index (BI) and plaque index (PLI) were examined; tongue coating was estimated with thickness (Tt) and area (Ta) on the dorsal surface of tongue.

RESULTSThe correlation was analyzed with Spearman method. There was a significantly positive correlation between OR, VSCs levels and BI, PLI, and Tt, respectively (P < 0.01). OR and VSCs levels was also related with Ta (P < 0.05). There was a weakly correlation between VSCs levels and PD, and the proportion of PD >/= 4 mm sites (r = 0.26, P < 0.05). No correlation between OR and PD, and the proportion of PD >/= 4 mm sites was existed. Reduction of VSCs levels after cleaning tongue coating was statistically significant (t = 10.15, P < 0.01), and also significantly related with thickness and area of tongue coating (P < 0.01).

CONCLUSIONSIn present study, OR and VSCs levels were significantly correlated with gingival inflammation (BI), condition of oral hygiene (PLI), and tongue coating. The relationship between OR, VSCs levels and periodontal probing depth was not found obviously. VSCs levels were significantly reduced after cleaning tongue coating, but the percentage of reduction was less than that of the previous studies.
