The efficacy of cognitive-behavioral intervention on anxiety and oral health-related quality of life in adult orthodontic patients / 中华行为医学与脑科学杂志

Objective To explore the influence of cognitive-behavioral intervention on the anxiety and oral health-related quality of life in adult orthodontic patients.Methods 152 adult orthodontic patients whose MDAS scores were greater than 11 were divided into the intervention group and the control group according Multistage Grouping Process.The former were treated with MBT appliance combined with cognitive-behavioral intervention,and the latter were treated with MBT appliance only.The State-Trait Anxiety Inventory(STAI) was adopted to evaluate anxiety in all patients during orthodontic treatment,and the UK oral health-related quality of life questionnaire(OHRQoL-UK) was adopted to evaluate the oral health-related quality of life in all patients before and after orthodontic treatment,respectively.Results 1.After 3 and 6 months cognitive-behavioral intervention,the scores of SAI in the intervention group(50.37±9.18,35.65±8.92) were significantly reduced compared to the control group(56.62± 10.52,54.13± 10.03) (P＜0.01).After 6 months cognitive-behavioral intervention,the scores of TAI in the intervention group(47.92±6.82) were significantly reduced compared to the control group(51.52±7.41) (P ＜0.05).2.After the orthodontic treatment,the scores of OHRQoL-UK in the intervention group(58.27±13.43) were significantly improved compared to the control group (51.99± 11.69) (P＜ 0.01).3.The oral health-related quality of life after the orthodontic treatment were significantly related to post-treatment anxiety of adult orthodontic patients(r=-0.192 ～-0.459,P＜ 0.05).Conclusion Cognitive-behavioral intervention can effectively reduce anxiety and improve the oral health-related life quality in the adult orthodontic patients.

General self-efficacy and body dysmorphic disorder of patients with deformities of the maxillofacial region / 中华行为医学与脑科学杂志

Objective To observe the self-efficacy and body image changes of the patients with oral and maxillofacial deformity in pre-and post-operative.Methods 183 patients with oral and maxillofacial deformity and 200 relatives as control group were measured by applying General Self-Efficacy Scale (GSES) of Chinese version and Self-rating Scale of Body Image(SSBI).Postoperative satisfaction degree was scored by applying attitude measurement method of interval scale.Perioperative GSES,SSBI score,and postoperative satisfaction degree were statistically analyzed.Results GSES score (26.79 ± 5.26) was lower than that in control group in preoperative (29.69 ± 5.37),and the difference was statistically significant (P ＜ 0.05).While SSBI score (24.35 ± 8.59) was higher than that in control group(11.04 ± 6.67),and the difference was also statistically significant (P ＜ 0.05).GSES score in postoperative(29.52 ± 3.80) was significantly higher than that in preoperative (P ＜ 0.05).SSBI score in postoperative(18.88 ± 8.19) was significantly higher than that in preoperative (P ＜ 0.05).Postoperative satisfaction was comparatively lower for the patients whose GSES score was higher than 32 and 36 for SSBI in preoperative.Conclusion Oporation can enhance the self-efficacy of patients with oral and maxillofacial deformity and reduce the incidence of patients with body dysmorphic disorder tendency.

Exploration on Morphology of Parv Interneurons and Their Distribution in Striatum in Rats / 中山大学学报(医学科学版)

[Objective ] Intrastriatal Parr interneurons are considered to be the junction between striatal input and output neurons. This study purposes to confirm the morphology of Parr neurons and their distribution in striatum. [Method] Adult male SD rats were perfused and the brains were removed. The sections were conducted with a semiconductor-frozen microtome, then single labeling and double labeling were immunocytochemically conducted with PAP technique. Positive neurons were observed, counted, and calculated, and analyzed with SPSS. [Results] The distribution of Parr positive neurons in striatum was inhomogeueous, and was the most dense in the dorsal lateral area (P<0.001) ; the distribution of Parr positive neurons in matrix compartment was apparently more than patch compartment (82.0% vs 18.0%, P<0.001); Parr positive neurons in striaturn were medium-sized cell bodies with polygonal or oval in shape (mean diameter is 11.68 μm), and were larger in the lateral area than that in the medial area (P<0.01) ; the positive dendrites were dense and smooth without dendrite spines; the positive axons 1 were slender and their collaterals extended in striatum. [Conclusion] The characteristic of Parr positive neurons collecting mostly in lateral striatum and matrix eompartment, as well as their traits of intemeurons, indicated that they would affect the striatal projection neuronal function.

Study on the supercritical CO_2 extraction of curcumolin Curcuma with uniform design and regression analysis / 中成药

AIM: To optimize the extraction process for the active components in Curcuma by supercritical CO_2 as guided by the contents of curcumol in Curcuma. METHODS: Gas chromatography was used to determine the contents of curcumol in the extract.Uniform design and path analysis were used to optimize SFE process. RESULTS: The optimum process was established as following:20 MPa as extracting pressure,40℃ as extracting temperature,120 minutes as dynamic extracting time and 20 minutes as static extracting time,24 mL of 70% alcohol as modifier.The absolute error of the predicted value from the model was smaller than 0.6%. CONCLUSION: The regression model is very notable and reasonable and can forecast results precisely.
