Objective To investigate the expression and change of cytoglobin(Cygb)gene on hypoxicischemic brain damage(HIBD).Methods Fifty SD rats of 7days old were divided into four study groups and one control group.The brain tissues were taken at 4hours,12hours,24hours and 48hours after the onset of HIBD.Cygb mRNA was determined by the reverse transcription PCR.One-way method of GraphPad Prism was used for statistics.Results The fragment length of PCR products was identical with experimental design.The expression level of Cygb gene increased at 4h after ischemia,and peaked at 24h.48h after HIBD,the Cygb gene level began to decrease.Conclusion The expression of Cygb in brain tissue increased rapidly after HIBD of newborn rats,suggesting that Cygb may have important function in the protection process of HIBD.

Objective To observe the effect of connect meridians inducing Yin from Yang on muscle-tension after cerebral infarction. Methods 82 patients with cerebral infarction in Second Hospital of Harbin from 2010 to 2014 were divided into observation group (n=41) and control group (n=41) according to hospitalization order. The observation group accepted acupuncture of connecting meridians inducing Yin from Yang, and the control group accepted the traditional acupuncture method for 2 weeks. The situation of spasticity, the motor limb function of limbs, and activities of daily living were evaluated with modified Ashworth Scale (MAS), Clinic Spasticity Index (CSI), Fugl-Meyer Assessment (FMA) and Barthel index (BI), respectively. Results Compared with the control group, the score of MAS decreased (t=2.212, P=0.030), the score of CSI decreased (t=2.514, P=0.014), the score of FMA increased (t=4.288, P<0.001), and the score of BI in-creased (t=2.970, P=0.004) in the observation group after treatment. Conclusion The acupuncture of connecting meridians inducing Yin from Yang can reduce the muscle-tension of limbs, improve the motor function and increase the activities of daily living.

Objective To probe into the clinical features, ways of diagnosis and treatment measures of concurrent paratyphoid fever A after renal transplantation. Methods The 5 patients were all town or village people under the county level. After the operation, the immunosuppressive scheme of ciclosporin A (or Tacrolimus) + mycophenolate mofetil (MMF) + prednisone acetate was adopted. One case was caused by catching cold and the rest 4 had no any distinct inducement. Five patients fell ill respectively at the 5th, 7th, 7th, 9th and 14th month after the operation. On the admission, the 5 patients suffered from gastrointestinal symptoms such as vomiting and diarrhea to varying degrees; 3 from toxic symptoms such as fever, intolerance of cold, hypodynamia and headache; 3 from symptoms of the respiratory system such as stuffy nose and congestion of throat; 1 from elevation of blood pressure; 1 from relative slow pulse. In 3 patients with decrease of urine volume, 1 suffered from gross hematuria, swelling of transplanted area of the kidney, pain on pressure and rise of blood pressure. Only 1 patient's paratyphoid fever A antibody in the Widal's test gastroenteritis or untoward reaction of MMF and the curative effect was bad. After definite diagnoses,the combined treatment of the third-generation cephalosporin and FQNS were given to all of them.After treatment for 7-10 days, the symptoms in all patients all disappeared. During the treatment, 1 patient was diagnosed as acute rejection and given the methylprednisolone shock for 3 days. After that, the patient's graft function was improved; 3 patients suffered from relatively great fluctuation of blood concentration of immunosuppressive agent and toxic symptoms such as decrease of the graft function, etc. After adjustment of dosage, their indicators of renal function became normal. Conclusion Early symptoms and accessory examinations of paratyphoid fever A after renal transplantation lack specificities. Diagnosis of paratyphoid fever A after renal transplantation mainly depends on blood culture. Drugs of first choice include FQNS and the third-generation cephalosporin. During the treatment, the doctor should closely monitor blood concentration of the immunosuppressive agent.

Objective: To investigate the effects of different doses of aerobic exercise on the microvascular function of habitually sedentary college students. Methods: A total of 69 students from Hubei Minzu University were recruited and divided into sports group A, sports group B and control group, with 23 students in each group (12 boys and 11 girls). The exercise group received 12 weeks of aerobic exercise intervention, in which group A exercised 1-2 times a week, group B exercised≥3 times a week, and the control group did not carry out any systematic sports. Microvascular response, Transcutaneous partial pressure of oxygen(TcpO 2), Nitric oxide, Nitric oxide synthase (NOS) and En dothelin-1 (ET-1) were measured before and after the test. Results: After the test, the microvascular reactivity showed group and time interaction( P <0.01), in which exercise group B was greater than that of control group and exercise group A ( P <0.01). There was no significant difference between exercise group A and control group ( P >0.05), but the percutaneous partial pressure of oxygen ( P =0.53) had no time interaction with other groups; NO( F =6.32) and NOS( F =7.91) had group and time interaction, in which exercise group B was greater than control group and exercise group A ( P <0.01), and there was no significant difference between exercise group A and control group ( P >0.05). Conclusion There is a "dose effect" relationship between aerobic exercise and microcirculatory blood perfusion and endogenous NO. Continuous aerobic exercise ≥3 times a week for 12 weeks improved microcirculatory blood perfusion and promoted endogenous NO production in sedentary college students, but doing aerobic exercise for 1-2 times a week had no significant effect on microcirculatory blood perfusion and endogenous NO.
