In recent years, remote ischemic preconditioning is found as a novel way to protect the brain, which may be achieved through nerve pathways, humoral factors or nerve-humoral interaction. The molecular mechanisms for the protection might be related to mitochondria ATP-sensitive potassium channel, mitogen-activated protection kinase, mammalian target of rapamycin, including nitric oxide synthase and cannabinoid receptors. The aim of this review is to explain the mechanism of action of remote ischemic preconditioning on brain protection, as well as the possible direction of clinical application.

OBJECTIVE: To analyze the use situation and trend of cardiovascular and cerebrovascular drugs during 2007～2009 in a military sanatorium, and provide reference for the rational use of cardiovascular and cerebrovascular drugs and its essential medicines. METHODS: Cardiovascular and cerebrovascular drugs in the rehabilitation center during 2007～2009 were analyzed statistically in the respect of category, consumption sum and DDDs. RESULTS: The consumption sum and DDDs of cardiovascular and cerebrovascular drugs were increasing in the past three years. And its essential drugs account for 94.8%.The most widely used drugs were cerebrovascular drug, brain metabolism drug, nootropics and antihypertensive drugs. Oxiracetam and Xueshuantong were widely used cerebrovascular drug, brain metabolism drug and nootropics. Amlodipine were widely used antihypertensive drugs in the clinic. CONCLUSION: Cardiovascular and cerebrovascular drugs and its essential drugs were characterized with complex classification, numerous categories, extensive application and potential market demand, which require rational use of drug should be strengthened.

Objective:To get the prevalence of attention-deficit hyperactivity disorder and in Children. Methods:The subjects were 2188 children who were 4~16 year-old in Wuhan. We had their parents filled the investigation forms. Diagnosis was made according to criterion of attention-deficit hyperactivity disorder in DSM-IV. Results:of behavior problems were got through Achenbach Behavior Questionnaires. Those who were diagnosed as ADHD were classified into three subtypes: predominantly inattentive type; predominantly hyperactive-impulsive type and com-bined type. All suspicious patient and their parents were invited to have the diagnostic talk. Results: (1) The rate of ADHD was 13.58%. ADHD-C, 2.63%; ADHD-I, 8.27%; ADHD-HI, 2.68%. The male, 18.57%; female,8.78%. The ratio of male: female was 2.24:1。(2) There was significantly difference of rate of ADHD between age groups. The rate of 4~5 years-old was 15.88%, that for 6~11 years-old was 15.85%; and for 12~16 yeas-old, 9.98%. The rate of ADHD decreased by aging, especially the group of ADHD-HI. But the rate of ADHD-I was still increased, especially the male group of 6~11 years-old, 12.19%. (3) There was significantly difference of sociality ability between ADHD children and the normal. (4) No matter which age and sex, the scales of behavior problem of ADHD children were higher than the normal children. And the number of factors of behavior problem of ADHD children increased by ag-ing.Conclusion: The rate of ADHD-I was the highest in the three subtypes defined by DSM-Ⅳ, especially among boys 6~11-years-old. The rate of ADHD is significantly associated with sex and age.

Diabetic peripheral neuropathy is a common complication of diabetes mellitus,can occur in some patients with painful diabetic peripheral neuropathy.The occurrence of PDPN is related to many factors,such as long term severe hyperglycemia and metabolic disorders,deficiency of neurotrophic factors, disorder of microcirculation,increase of oxygen free radicals in oxidative stress and disorder of immune func-tion.Mitogen activated protein kinase (MAPK)is a kind of serine /tyrosine protein kinase ,which can widely expressed in cell,and can be involved in the pathophysiological process of stress,inflammation,cell cycle and apoptosis through increased nuclear transcription factors.P38MAPK signaling pathway is an im-portant branch of the MAPK,this overview focuses on the research progress of p38MAPK signaling pathway in the pathogenesis of PDPN.

Objective To evaluate the effect of oral health instructions in nursing of marsupialized jaw cysts. Methods 46 patients with cysts of jaw were divided randomly into two groups (education group and control), 23 in each. In addition of normal nursing processes in both groups, patients in education group were offered more oral health instructions, such as pathogenesis of jaw cysts, mechanism of marsupialization, wear and clean of a cyst plug, and oral hygiene maintenance. 12 months later, compliance, satisfaction, treatment effect and oral hygiene condition of the patients in the two groups were studied and compared. Results 100%of patients in the education group could return to clinical visits on time and 96%of patients did cyst rinsing after every meal, which were significantly higher (χ2=6.9, P<0.05) than in the control (74% and 70% respectively). Patients′satisfaction in the two groups were also significantly different (χ2=9.109,P<0.05). Patients in the education group were much more satisfied with the treatment procedures than control. The treatment effect of the cyst in the education group [good (83%), moderate (17%), not so good (0%)] was significantly (χ2=7.793, P<0.05) better than control (good (43%), moderate (52%), not so good (5%)]. The secondary infection rates in the two groups were similar (χ2=1.022, P>0.05). Oral hygiene condition of patients in the education group was better than control in Debris Index (χ2=9.576, P < 0.05) and Plaque Index (χ2=8.212, P < 0.05). Conclusions Oral health instructions played positive role in improving patients′ compliance, degree of satisfaction, treatment effect and oral hygiene condition in patients with jaw cysts.

OBJECTIVE:To analyze the utilization of different dosage forms of essential drugs in the clinical practice in our sanatorium and the tendency of drug use of patients.METHODS:The utilization of essential drug in our sanatorium were analyzed statistically in respect of drug category,constitution ratio of drug use.A questionnaire survey was carried out to survey the tendency of drug use of patients.RESULTS:Tablet was the most common dosage form in the clinic.Antibiotics and drugs for clinical therapy had complete dosage forms.The common dosage forms used patients were tablets and capsule,etc.CONCLUSIONS:Patients of our sanatorium select drugs tendentiously.The tendentious selection of drug is no difference in each age group.

Objective Three-dimensional(3D) automated ultrasonic volume measurement is becoming favorable in clinical application and turns to be an important direction .The article was to evaluate the consistency of two-dimensional (2D) and three-di-mensional ultrasonography in the diameter measurement of single follicle . Methods 438 single folliculars were respectively meas-ured by the same sonographer in 2D and 3D ultrasonic measurement.2D diameter, 3D mean diameter and 3D virtual ball diameter of every single follicle were recorded , and Bland-Altman method were used to evaluate the consistency of the results by these two meth-ods. Results In the consistency analysis on the diameter measurement of single follicle by 2D and 3D mean diameter measurment methods, d equaled -1.06 mm, and 95% LoA range covered the range of -4.82 mm to 2.70 mm.95% CI of 95% LoA range,-5.21 mm to 3.08 mm, was beyond the settings of clinical acceptable error limit range , -3.56 mm to 1.44 mm, showing poor consis-tency.Likewise, in the research of the consistency in the measurement of 2D diameter and 3D virtual ball diameter in the diameter measurement of single follicle , d equaled -0.07 mm , and 95%LoA range covered the range of -3.11 mm to 2.98 mm.95%CI of 95%LoA range, -3.43 mm to 3.29 mm, was beyond the settings of clinical acceptable error limit range , -2.57 mm to 2.43 mm, showing poor consistency . Conclusion 2D and 3D ultrasound measurements in the diameter measurement of single follicle are not consistent.However, considering the objectivity and accuracy of the results , 3D ultrasonography still has an advantage over 2D ultra-sonography , which can provide more acurate aid for assisted reproductive technology .
