ObjectiveTo search for the optimum external masking time and tonal models for patients with tinnitus.MethodsTwenty-seven patients with cochlear tinnitus were selected respectively from three different out-patients departments and divided into three groups. Nine patients in every group were treated with different masking parameters according to factorial design which had three masking noises, i.e. narrow band noise (NBN), wide band noise (WBN), speech noise (SN),and three masking time ranges, i.e. 15,30,45 minutes. The results before and after treatment were compared and analysed with analysis of variance (ANOVA). ResultsThe treatment effect when masking for 15 minutes was worse than that for 30,45 minutes, but there was no difference between 30 and 45 minutes. The NBN had the best effect when tinnitus signal was single, the WBN was effective for tinnitus with multiple sounds. ConclusionNBN or WBN masking for 30 minutes showed better therapeutic effect.

Objective To evaluate the therapeutic effect of long-pulsed Nd:YAG 1064 laser on hyperplastic scars by using a rabbit ear model.Methods Five female and five male New Zealand long-ear white rabbits weighting 2.0-2.5 kg were used in this experiment.Four square full-thickness skin wounds sized 1.5 cm x1.5 cm were created on the ventral surface of each ear to develop a model of hyperplastic scar.Finally,a total of 74 hyperplastic scars developed on the 80 wounds,and the scars on the left and right ears served as the control (unirradiated) and treatment (irradiated with long-pulsed 1064 nm Nd:YAG laser) group,respectively.After 30 days of irradiation,the color and texture of scars were observed and the scar thickness was measured by color Doppler ultrasonogTaphy.Then,the scars were harvested followed by the analysis of density of fibroblasts and microvessels as well as the changes in collagen fibers in scars by HE staining,CD31 staining and Masson staining,respectively.Results A decrease was observed in the color,hardness and thickness of scars in the irradiated ears compared with the unirradiated ears.The average thickness of scars,microvessel density and fibroblast density in scars were significantly lower in the treatment group than in the control group(2.137vs.3.089 am,t=5.72,P<0.01;38.333/mm2vs.68.056/mm2,t=4.93,P<0.01;166.940/mm2vs.355.000/mm2,t=13.36.P<0.01).Masson staining revealed a disorganized arrangement of collagen fibers in the control group but a sparse and regular alignment in the treatment group.Conclusion Long-pulsed 1064 nm Nd:YAG laser may promote the shrinkage and suppress the hyperplasia of scars.

Disseminated malignancy is the main cause of cancer-related death.The spontaneous circulation of tumor cells is responsible for distant metastasis;therefore it is of potential importance to specifically and sensitively detect the circulating tumor cells,which not only allows for more accurate prediction of cancer prognosis,but also helps to tailor individualized anticancer treatment.This paper reviews the enrichment,detection and analyzing methods of circulating tumor cells.

Objective To analyze the reasons of the occlusal disorder after mistaken concrescence of maxillofacial fracture, to observe the effect of the physiotherapy for the masticatory movement and the masticatory efficiency after occlusal reconstruction with fixed prosthesis. Methods The reasons of occlusal disorder of 45 patients were analyzed by reviewing the case history and clinical examination. Ultrasound diathermy and laser irradiation were used to help improve masticatory movement. The fixed prosthesis was used to reconstruct the occlusal relationship. Masticatory efficiency was measured with the method of sift out before treatment, one month and one year after treatment. Results The main reason of occlusal disorder was the delay of treatment because of the other treatment of body after trauma. The physiotherapy was effective in improving the masticatory movement. Statistically analysis showed the significantly difference before and after occlusal reconstruction with fixed prosthesis ( P

7.Rehabilitation and Exercise for Senior Coronary Heart Disease (review)
Chinese Journal of Rehabilitation Theory and Practice 2010;16(5):421-422
The rehabilitation exercise has been found to be an important part of the treatment of the senior coronary heart disease in the recent researches. The senior patients with coronary heart disease are always complicated, so the exercises should start with low intensity and increase gradually. It is important to pay attention to the warm up and relaxation before and after the exercises. There are few patients accepted rehabilitation, which need pay more attention on it to help the senior patients improve their quality of life.

Objective To explore the content and gene expression of endothelial nitric-oxide synthase (eNOS) in heart of hyperlipidemia apoE-/- mice. Methods apoE-/- mice were fed with high fat diet as high-fat diet group (n= 7) and normal fat diet as control group (n = 6) for 12 weeks. Serum lipid profiles including total cholesterol (TC), triglyceride (TG), high density lipoprotein (HDL) and low density lipoprotein (LDL) were detected, eNOS mRNA expression in heart were determined by Real-Time RT-PCR, as well as protein expression by immunohistochemistry. Results Levels of serum TC, TG and LDL clearly increased in high fat diet group, while HDL decreased (P< 0. 01). mRNA and protein expression of eNOS in heart reduced in high fat diet group(P<0.01). Conclusions High fat diet may lead to hyperlipidemia in apoE-/- mice, which may down-regulate eNOS expression and decrease eNOS content in heart.

OBJECTIVE:To study the adsorbability of plastic transfusion bottle and infusion set to diazepam. METHODS:With the reference of plastic-bottled 5% glucose injection,HPLC was used to determine the changes of mass concentration of diazepam adding into plastic-bottled 5% glucose injection at different time;disposable plastic infusion set was connected to simulate intrave-nous infusion and determine the changes of mass concentration of diazepam in the liquid effluent at different time. RESULTS:The mass concentration of diazepam in glass infusion bottles group was higher than in plastic transfusion bottles group. The adsorbabili-ties of solutions showed the strongest at the time of 15-20 min. The mass concentration of the effluent liquid from the glass bottle group was about 80% of the original concentration and plastic bottle group was about 67%. As the time went on,the adsorbability was gradually saturated at 60 min and the concentration rose again;the mass concentration of the effluent liquid from the glass bot-tle group returned to 95%of the original concentration at 80 min and the plastic bottle group was about 75%of the original concen-tration. CONCLUSIONS:Both plastic infusion bottle and infusion set have strong adsorbability to diazepam. It is suggested that the dosage of diazepam should be increased by 25% to 33% while plastic-bottled 5% glucose injection is used as solvent for intrave-nous drip.
