Objective:To study the effect of electromyographic feedback therapy on hemiplegia of patients with cerebral infarction Method: 120 hemiplegic patients were randomly divided into study group (n=60) and control group (n=60) The former received electromyographic feedback trainings, 6 times a week for four weeks, in addition to regular medication All patients were evaluated with Fugl-Meyer Assesment and Barthel Index Results: The improvement of study group was greater evaluated by both methods Discussion:The eletromyographic feedback can improve motor function of hemiplegic patients and do benefit their activities of daily living

Objective: To study the effect of cognitive therapy in combination with electromyographic feedback therapy on diabetes patients with depression after cerebral infarction. Methods: 60 patients were randomly divided into study group (n=30) and control group (n=30) , The former received cognitive therapy and electromyographic feedback trainings in addition to regular medication. All patients were evaluated with Hamilton Depression Rating Scales (HAMD),Neurological Function Deficit scale(NFD)?Barthel Index(BI) and FPG (free plasma glucose), 2HPG (plasma glucose after 2 hours of a meal). Results: The improvement of study group was greater than the control group(P

Objective To investigate the clinical, hemorheology, transcranial Doppler (TCD) and auditory brainstem evoked response (ABR) features in senile sudden deafness.Methods The clinical manifestations, hemorheology, TCD, and ABR data in 82 patients with senile sudden deafness were analyzed retrospectively.Results (1) The primary symptoms mainly included tinnitus (65.9%) and vertigo (56.1%), which mostly occurred at daytime (53.7%).(2) Most of the patients had risk factors of arteriosclerosis such as hypertension (75.6%), diabetes (59.8%) and so on. These patients had more serious deafness.(3) There was no obvious relationship between high blood viscosity (61% of the patients) and the degree of deafness. (4) 85.4% of senile sudden deafness patients indicated vertebral-basilar artery insufficiency in TCD. There was a positive correlation between blood supply and degree of deafness. (5) The abnormal rate of ABR was 100%. WaveⅠdisappeared in most patients, which showed serious damage of auditory nerve. Disappearing of waveⅠ, Ⅲ, Ⅴ and Ⅰ～Ⅲ, Ⅲ～Ⅴ, Ⅰ～Ⅴ delitescence period delaying might be complicated with the damage of the structure of the brainstem and cochlea.Conclusions The morbidity and degree of senile sudden deafness are associated with insufficiency of blood supply of internal ears. TCD and ABR are sensitive and reliable methods in diagnosis, progression and prognosis of senile sudden deafness.

Objective To overview the clinical and endoscopic features of the ischemic colitis. Methods Retrospective analysis was conducted. Results Of the 60 cases, 87% were over 50 years, and females were more than males. 76.7% of the cases were associated with the basal diseases such as cardio cerebrovascular disorders, diabetes and hematological diseases as well as the history of abdominal operation. Colonoscopy showed mucosal edema, congestion, erosion and ulceration. 87.1% of the cases were cured after treatment and 16.7 % were improved. The outcome may be associated with the age, severity of the lesion, course, basal diseases and the complications. Conclusions Endoscopy plays a vital role in the early diagnosis of ischemic colitis.

Objective To observe the effect of rational-emotive therapy(RET)on rehabilitation of patients with depression after stroke.Methods 62 hemiplegic patients with depression after stroke were randomly divided into the RET group and control group with 31 cases in each group.All patients were evaluated with Hamilton Rating Scale for Depresstion(HAMD)and Barthel Index(BI)before and after treatment.Results After treatment,the scores of HAMD and BI of the patients in the RET group was superior to those in the control group(P<0.01).Conclusion The rational-emotive therapy is effective to improve not only depressive symptoms but also the quality of living.

Objective To investigate the effects of cognitive therapy combined with picture recognition training on depression after stroke (PSD).Methods Sixty patients with PSD after cerebral infarction were randomized into study and control groups.All accepted routine rehabilitation therapy.In addition,the study group accepted cognitive therapy combined with picture recognition training.The effects were assessed in terms of average reaction time and accuracy in picture recognition,and using the Hamilton depression rating scales (HAMDs) and the Barthel index (BI) before and after 4 weeks of treatment.Results The average reaction time and accuracy in picture recognition and the HAMD and BI scores improved significantly in both groups.The effects in the study group were significantly better than those of the control group.Conclusion Cognitive therapy combined with picture recognition training can alleviate depression symptoms and improve ability in the activities of daily living after stroke.

Objective Explore the individual difference in carbon monoxide (CO) poisoning and analyze whether females were be more resistant to CO poisoning.Methods We collected 207 cases of CO poisoning deaths, and then we analyzed the Carbonyl Hemoglobin (COHb) results sorted by different sources of CO.Results The source of CO had significant impact on the fatal COHb level, but gender was not significant in affecting COHb level. In addition, it is possible that children and elders were less resistant to COHb than adults.

Objective To investigate the characteristics of clinical course and outcome in elderly patients with nonvariceal upper gastrointestinal bleeding (NUGB) Methods The 206 hospitalized patients were devided into elderly group (≥60 yrs, 105 cases) and non elderly growp (

BACKGROUND:Compared with hydroxyapatite materials and other nano-hydroxyapatite composites, carbon fiber-reinforced nano-hydroxyapatite/polyamide 66 composites have been significantly improved in the mechanical strength, toughness, elastic modulus and other aspects. It can be used for repairing bone defects of loading parts. OBJECTIVE:To investigate the biocompatibility of carbon fiber-reinforced nano-hydroxyapatite/polyamide 66 composites in bone tissues. METHODS:Eight Bama mini pigs were taken to establish models of thoracic vertebral defects and implanted with carbon fiber-reinforced nano-hydroxyapatite/polyamide 66 composites. At 8, 16 and 24 weeks after implantation,the animals were sacrificed, respectively, for bone mineral density detection and hematoxylin-eosin staining. Blood samples for kidney and liver function tests were taken before and 1 and 8 weeks after implantation. RESULTS AND CONCLUSION: Hematoxylin-eosin staining of bone samples showed that the materials could bond with the bone defect interface without rejection, and could induce osteogenesis of chondrocytes. At 8 weeks after surgery, the broken ends of cancelous bone closed and the composite material was wrapped by granulation tissues. At 16 weeks after surgery, granulation tissues were organized and new bone developed directly from fibroblast cels. The new bone tissues were nearly fused with the end of cancelous bone. At 24 weeks after surgery, new bone tissue became mature lamelar bone, and the end of cancelous bone was connected tightly with the composite material. Bone mineral density of the implanted vertebra showed an increase trend at 8, 16 and 24 weeks after implantation. Over time, the bone mass was increased. The liver and kidney function tests showed that there was no significant difference before and after implantation. It is preliminarily believed that the carbon fiber-reinforced nano-hydroxyapatite/polyamide 66 composite has excelent histocompatibility and bioactivity without hepatic toxicity and nephritic toxicity.
