Objective To study the relationship between cognitive dysfunction and depression and event-related potential(ERP) in patients with silent brain infarction(SBI).Methods 68 SBI patients were tested by the Hamilton Depression Rating Scale for Depression(HAMD),scale of mini mental state examination(MMSE)and ERP;and the results were compared with those in 55 patients without cerebral infarction(control group).Results In the SBI group,the HAMD score was ≥17 in 31(45.6%)cases(depression subgroup)and

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

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.

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.

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 observe the relationship between serum bilirubin levels of elderly heart failure patients and type, clinical symptom and prognosis of the heart failure. To explore the pathophysiological role of heme oxygenase 1/CO bilirubin system in the pathogenesis of the heart failure. Methods Serum total bilirubin and direct bilirubin and indrect bilirubin levels of 57 inpatients admitted to our depatment because of heart failure from April 1998 to June 2000 were examined in the second day, first and second week after admission, respectively. Results (1) Compared with the recovery stage of the heart failure, the serum total bilirubin levels during the heart failure attack increased by 52 9% and 78 9%, respectively than the first and second week after the attack(26 1 ?mol/L vs 17 4 ?mol/L and 14 6 ?mol/L, P

Objective To investigate the possible mechanism of Compounded Sour Medicinal Herbs (CSMH) in preventing and amelioration type 2 diabetic mellitus (T2DM) rats chronic complication, by analyzing the effects of CSMH on the deposition of advanced glycation end products (AGEs) and gene expression of their receptor myocardial tissue in T2DM rats. Methods The rats were injected with streptozotocin (STZ) through peritoneum, and fed with high-fat and high-caloric diets to induce T2DM animal models. Then the rats were randomly divided into three groups:untreated group (model group), AG treated group and CSMH treated group. The deposition of AGEs and gene expression of RAGE in the myocardial tissue of T2DM rats were detected separately by fluorescence and real time PCR method. Results The deposition of AGEs and gene expression of their receptor in myocardial tissue in control group were lower than that of T2DM rats (P
