Objective To study the reporting status of notifiable infectious diseases in a general hospital,grasp epidemiological characteristics and patterns,and provide scientific basis for the preventive measures of infectious diseases.Methods Epidemic data of notifiable infectious diseases reported by a hospital in 2007 -2011 were ana-lyzed statistically.Results Reporting rate of notifiable infectious diseases was 0.40%(15 386/3 852 327)in 2007-2011 ,and were statistically different among each year (χ2 =94.93,P <0.01),the major age of reported cases were 14-45 years(46.70%),the main transmission routes were blood and sex (60.68%),followed by respiratory tract (33.06%).The reporting rates among different months were statistically different(χ2 =487.60,P <0.01 ),April ranked first for five consecutive years(0.53%),followed by December(0.51 %)and May(0.48%).The main repor-ted infectious diseases included viral hepatitis(42.82%),varicella(20.06%),syphilis(16.96%),rubella(5.41 %), and pulmonary tuberculosis(3.75%).Conclusion Bloodborne diseases,sexually transmitted diseases,and infec-tious respiratory diseases are the stress in the prevention and control of infectious disease,management should be in-tensified.

Objective To observe the effect of electromyographic biofeedback therapy(EMGBFT)on dysphagia in stroke patients.Methods Fifty-three stroke patients with dysphagia were divided randomly into an EMGBFT group and a control group.The patients of EMGBFT group were given EMGBFT,electrical stimulation therapy (EST)and dysphagia training,while those in the control group were given EST and dysphagia training.All the patients were assessed with Kubota drinking test before treatment and 30 days after treatment.Results After treatment swallowing function of patients in both groups improved(P ＜0.05).The effective rate was 76.92％ in EMGBFT group and 55.56％ in control group,with statistically significant difference between the two groups(P ＜ 0.05).It showed that the EMGBFT group has significantly better outcome than the control group after treatment(P ＜ 0.05).Conclusions EMGBFT combined with regular rehabilitation therapy can improve patient's motor and swallowing function.

BACKGROUND:Metabolic syndrome greatly harms the human body, and is affected by many factors. Through constructing diet-induced animal models, we can better analyze the relationship between nutritional factor and metabolic syndrome, and provide reliable references for the clinical treatment of this disorder. OBJECTIVE:To construct obese mouse models with high-fat diet feeding and discuss the relationship between nutritional factor and metabolic syndrome. METHODS:Thirty mice were selected and randomly divided into model group (n=20) and control group (n=10), and were fed with high-fat and normal animal feeds for 10 consecutive weeks. RESULTS AND CONCLUSION:Compared with the control group, after 1 week of feeding with high-fat animal feeds, body weight of mice in the model group raised, and differences gradualy increased with the feeding time increased. After 8 weeks of feeding, body mass index of mice in the model group significantly raised (P < 0.05). After 4 weeks of feeding, fasting venous blood glucose level of mice in the model group significantly raised, and showed a gradual rise trend with feeding time. After 5 weeks of feeding, fasting insulin level of mice in the model group also began to rise. The oral glucose tolerance test showed that mice in the model group showed a gradual downward trend of glucose tolerance with feeding time. After 8 weeks of feeding, serum levels of total cholesterol and high density lipoprotein cholesterol in the model group significantly raised (P < 0.05). After 10 weeks of feeding, serum levels of triacylglycerol, total cholesterol, low density lipoprotein cholesterol and high density lipoprotein cholesterol in the model group raised (P< 0.05). The results demonstrate that obese mouse models were successfuly constructed with high-fat diet feeding, which can simulate the natural progression of metabolic syndrome in human, moreover, the nutritional factor is closely related to metabolic syndrome.

BACKGROUND:Skin and soft tissue defects of hands are easy to appear due to different factors, such as trauma. Flap transplantation is a clinical treatment for soft tissue defects of hands. Dorsal foot flap, which is thicker with constant vessel traveling, is very suitable for repair of hand soft tissue defects. OBJECTIVE: To explore the success rate and survival rate of dorsal foot flap transplantation in the repair of hand skin and soft tissue defects. METHODS: A retrospective analysis was performed on the clinical data of 86 patients with skin and soft tissue defect of hands. These patients were respectively given conventional skin wound skin grafting (control group) and dorsal foot flap transplantation (observational group). Hand appearance, infection rate, perception recovery and complications were observed during the postoperative folow-up. RESULTS AND CONCLUSION:Skin flaps al survived after grafting, and the texture of flaps was good. Patients were satisfied with hand shape and the recovery of hand function. After flap transplantation, one patient had local skin necrosis at the donor region, and the scar healed after dressing; another patient had venous crisis, and was given vascular re-anastomosis. In the observation group, the postoperative appearance was better than that of the control group, the infection rate was lower than that of the control group, the perception recovery was better, and there were fewer complications (P < 0.05). These findings suggest that the dorsal foot flap transplantation is better to repair skin and soft tissue defects in the hand.

Objective To observe the effects of psychological supportive therapy on the activities of daily living (ADL) and depression after cerebral hemorrhage. Methods 60 cases with mild or medium depression according to 17 items Hamilton Rating Scale for Depression (HAMD-17) after cerebral hemorrhage were divided into treatment group (n=30) and control group (n=30). All of them accepted physical exercise, and those in the treatment group accepted psychological supportive therapy in addition. They were assessed with Functional Independence Measure (FIM) and HAMD-17 before and after the treatment. Results After 2 months of treatment, the score of FIM increased more in the treatment group than in the control group (P<0.001), and the score of HAMD-17 decreased (P<0.001). Conclusion Psychological supportive therapy may promote the recovery of ADL and depression for patients post cerebral hemorrhage.

Objective To study the clinical and pathological features in the elderly patients with chronic inflammatory demyelinating polyneuropathy (CIDP). Methods The features of the clinical manifestation, cerebrospinal fluid, electromyogram(EMG) and the biopsy results of sural nerve were presented and analyzed in 11 elderly patients with CIDP. Results Two cases had history of upper respiratory tract infection before the onset. As the initial symptoms , there were three cases with distal limb numbness, five cases with both distal lower extremities numbness, two cases with both distal upper extremities numbness and one case with difficulties to raise his head. Motor disorder was common to all the patients. There were eight patients with sensory dysfunction, three with limb muscle atrophy, one with muscle tenderness, eight with tendon reflexes weakened or disappeared, five with cranial nerve damaged, three with the autonomic nerve lesion, one with respiratory muscle involved, three with relapse. The score of the peak incidence as Modified Rankin was 3.02 points on average. Five cases had obvious albuminocytolgoic dissociation by the examination of cerebrospinal fluid, ten cases had neurogenic damage and one case had a combined myogenic and neurogenic damage by the EMG. The biopsy showed that six cases were with amyelination,six cases with inflammatory cell infiltrated, two cases with obvious remyelination, two cases with auxiliary fibers degeneration.And the methylprednisolone therapy was effective for eight cases. Conclusions The numbness of the distal limb is the initial symptom of the elderly patients with CIDP,most of whom are with sensory dysfunction ,and some with cranial nerves and autonomic nerve damage. The sural nerve biopsy has an important value for the diagnosis of the elderly with CIDP. The methylprednisolone therapy is proved to be effective for most patients.

Objective To study the effect of Rho-kinase inhibitor on experimental allergic neuritis. Methods 54 female Lewis rats were divided into three groups; EAN group, EAN + Rho-kinase inhibitor group, and CFA group. The rats were sacrificed on the 9th day, 17th day, and 26th day after immunized. The changes of weight, EAN incidence, and mean day of onset, mean maximum clinical score, and histopa-thology were observed. Results The clinical course in EAN group reached peak on the 17th day. Compared with EAN group, the weights of Rho - kinase inhibitor group were increased, while EAN incidence, mean day of onset delay, and the clinical scores in Rho-kinase inhibitor group were significantly decreased, ( P < 0.01) , and the demyelization and inflammation cells infiltrating was ameliorated in spinal nerve. CFA group didnt show any clinical manifestation. Conclusions Rho - kinase inhibitor may ameliorate the development of EAN through inhabiting the Rho/ROK signal pathway.
