Objective: To study the effects of dental treatment and psychological treatment on daytime brycomania. Methods: 16 patients with daytime brycomania were treated with a series of measures, including eliminating dental nidi, application of bite plate on the front teeth so as to make barriers to abrasion information coming into the center occlusions, and administering medicine with psychological and mental treatment. Follow up was conducted for 6 months.Results: The symptom was relieved after one to two- week treatment; complete recover was achieved in all patients in 2 months and no recurrence was observed in 6 months.Conclusion: The study shows emotional and psychical disorders may be factors for daytime brycomania, psychological treatment is an important part for cure.

Objective To evaluate the toxicity and efficacy of thermotherapy used with a streptococcus A preparation (OK-432) and cisplatin for treating malignant pleural effusion (MPE),and to assess patients' tolerance.Methods A total of 158 MPE patients were randomized into experimental and control groups.Closed drainage of the thoracic cavity was conducted with all the patients using a central venous catheter,and systematic chemotherapy was administered individually on the basis of each patient's condition.Patients in the control group were treated with intrapleural administration of OK-432 (0.5 mg) and cisplatin (40-60 mg) weekly for a maximum of 4 weeks,while those in the experimental group were given 60min of high frequency electrical thermotherapy 30-60 min after the administration of the drugs.The thermotherapy was at 40-43.5 ℃ and administered twice a week.Efficacy,quality of life and toxicity were compared between the two groups.Results The overall response rate in the experimental and control groups was 90.6% and 79.5% respectively;and grade I-II toxicity was similar.No grade Ⅲ or more serious toxicity was observed.The life quality scores in both groups were significantly improved after treatment.Conclusions Thermotherapy combined with intrapleural OK-432 and cisplatin can improve the effectiveness of therapy and life quality in MPE patients without increased toxicity.

Objective To investigate the clinic application of micro-implant anchorage in the treatment of maxil-lary protrusion malocclusion. Methods Twenty-two patients,aged 18 to 25 years old,with maxillary protrusion were divid-ed into two groups:experimental group and control group with 11 patients in each group. All patients were treated with ex-traction. Micro-screw palatal implant was used in the cases of experimental group as orthodontic anchorage ,and traditional anchorage composed of extraoral arch used in the cases of control. The cephalometric films were measured before and after treatment. Statistical methods were utilized to analyze the morphological changes of facial profile and hard tissues in both groups. Results The values of U1-NA(mm:3.08±1.18 vs 8.15±3.05) and U1-SN(101.90°±3.50° vs 117.90°±6.05°) were sig-nificantly decreased after treatment compared with those before treatment in the experimental group ( P<0.01). The value of U1-L1(123.98°±5.78°vs 103.89°±8.95°) was significantly increased after treatment (P<0.01). In control group, the values of U1-NA (mm:5.01±1.34 vs 9.12±2.13) and U1-SN(101.90°±3.97° vs 114.87°±7.69°)were significantly decreased after treat-ment. The values of U1-L1(126.01°±3.12°vs 112.98°±5.98°) and U6-PtPNS(mm:21.45±2.43 vs 18.36±2.19)were significant-ly increased after treatment (P<0.05). The value of U1-L1(19.48°±8.90° vs 13.01°±5.90°) was significantly changed in exper-imental group than that of control group, but the value of U6-PtPNS(mm:0.90±0.29 vs 3.78±0.12)was significantly changed in control than that of experimental group (P<0.01). Conclusion The maxillary protrusion malocclusion with micro-im-plant anchorage can be used as treatment for patients with maxillary protrusion that needs strong anchorage.
