Abstract：

Objective To explore the changes and the clinical significance of 5-hydroxytryptamine (5-HT), dopamine (DA) levels in serum and cerebrospinal fluid (CSF) of patients with delayed encephalopathy(DEACMP)after acute carbon monoxide poisoning. Methods The dynamic detection of 5-HT and DA levels in serum and CSF from 42 patients with DEACMP was performed with high performance liquid chromatography (HPLC). The condition changes of patients with DEACMP were analyzed with three types of scales: the activity of daily living scale (ADL), information memory concentration test (IMCT) and Hasegawa's dementia scale(HDS); these changes were compared with those from 38 other encephalopathy patients and 38 nonencephalopathy patients, respectively. Results Before treatment, the serum 5-HT and DA levels [(662.61 ± 178.50) and (155.74± 60.32) nmol/L, respectively] of DEACMP group were both significantly lower than those[(914.08±198.04) and (225.70±48.53) nmol/L] of nonencephalopathy group (P＜0.05); the serum DA level of DEACMP group was also significantly lower than that [(243.57±66.94) nmol/L] of other encephalopathy group (P＜0.05); the serum 5-HT level of DEACMP group was not significantly different from that [(729.54±299.87 ) nmol/L] of other encephalopathy group (P＞0.05). After treatment, the serum 5-HT and DA levels[(714.08±170.47) and (192.18±33.07 nmol/L, respectively)] of DEACMP group elevated to various extent, but only serum DA level was significantly higher than that before treatment (P＜0.05). Before treatment,the CSF 5-HT and DA levels of DEACMP group were significantly lower than those of nonencephalopathy group and those of other encephalopathy group (P＜0.05). After treatment, the CSF 5-HT level (232.44±54.28 nmol/L) was similar to normal level and significantly higher than that before treatment (P＜0.05); the CSF DA level[(56.83±12.85) nmol/L] of DEACMP group increased only slightly (P＞0.05). In DEACMP group, ADL score (50.64±7.23), HDS score (8.55±8.08) and IMCT score (4.95±7.30) before treatment were significantly different from those (8.5 ± 8.08, 4.95 ±7.30 and 15.64 ± 10.90) after treatment (P＜0.01). In DEACMP group, there was a negative correlation between DA level changes and HDS score changes, when the DA levels and HDS scores before treatment were compared with those after treatment (P＜0.05). Conclusion The dynamic changes of 5-HT and DA levels in serum and CSF of patients with DEACMP consisted basically with the patient's condition change. The dynanically detected 5-HT and DA levels can be used as the biological indicators to reflect the condition change and treatment effects of DEACMP patients.

Objective To observe the clinical efficacy of orthodontic treatment for displacement of anterior tooth caused by periodontal disease. Methods Forty-seven patients with displacement of anterior tooth caused by periodontal disease were divided into study group (26 cases) and control group (21 cases)according to the therapy method, the study group received periodontal basic treatment combined with orthodontic treatment, while the control group only received periodontal basic treatment, the changes of periodontal pocket depth, bleeding index, anterior coverage, overbite, alveolar bone height in two groups before and after treatment were observed and compared. Results The periodontal pocket depth, bleeding index, anterior coverage and overbite of study group after treatment were (3.12±0.53) mm, (27.30±4.25)%, (2.53 ± 0.76) mm and (2.18 ± 0.53 ) mm respectively and which were significantly lower than those before treatment [(5.35 ± 0.68 ) mm, (97.60±7.53 )%, (6.22±1.43 ) mm, (4.53±2.25)mm], the difference was statistically significant (P＜ 0.05 ), and the decrease extent was more obvious than the control group, the difference between two groups was statistically significant(P＜0.05); the above indicators in control group after treatment also dropped, but compared with those before treatment there was no significant difference (P ＞0.05); the alveolar bone height in both groups had no obvious change before and after treatment.Conclusion Periodontal basic treatment combined with orthodontic treatment can correct the malposed anterior teeth, improve the periodontal conditions, it has good application prospects.
