Objective:Following the detection of the safety of nerve and muscle stimulators YY 0607-2007 standard, approach the characteristics of nerve and muscle stimulators. Methods: By understanding the standards of particular requirements for the safety of nerve and muscle stimulators and test method for measuring output characteristics of the nerve and muscle stimulators, different types of the products were received multiple detections, analysis, compare and make summary of the features of measuring output characteristics of products. Results:Through proposing the highlights before the detection, sorting complex detection conditions, identifying detection contents and reasonable detection order, combined with the characteristics of nerve and muscle stimulators to make the standard rules more reasonable. Conclusion: It made the detection of output characteristics more convenient and avoided the occurrence of false and missing detection.

In reviewing and analyzing the study on the clinical selection of the acupoints for peptic ulcer in the recent ten years,it was found out that peptic ulcer was mostly treated by combination of multiple acupoints clinically,by the combination of Front-mu point and Back-shu point of the spleen and stomach,and the combination of Front-mu point and Back-shu point of the spleen and stomach with Lower He-sea point,indicating that Front-mu point and Back-shu point of the spleen and stomach and Lower He-sea point have the important functions in the treatment of peptic ulcer.

Objective Through analyzing nursing course-teaching plans of 10 representative higher vocational colleges,to realize advantages of the curriculum implementation and contents to be improved from the practical teaching perspective,to review the application of China's educational objectives as well as to provide the reasonable choice and practical support for deepened teaching reforms.Methods Statistical models were employed in analyzing 10 colleges' class hours and course composition.The results were compared with relative guidance documents in national scope.Results All 10 colleges' practical teaching relevant indicators exceeded the national criteria in running higher vocational colleges,but deviations were appeared in response of the national guidance of the nursing education,especially in clinical clerkship.Conclusions The quality guarantee of nursing course-teaching should be improved.A national policy should be implemented to combine the professional education accreditation with the nursing practitioner admittance,apply the minimum professional education standards to achieve the educational quality guarantee and guidance in each level.

Objective To study the clinical features bone marrow biopsy of secondary myelofibrosis(SMF).Methods 69 patients with secondary myelofibrosis were analyzed retrospectively,and the relationship between myelofibrosis degree and megakaryocyte count was analyzed. Results Analysis of 69 cases of patients with SMF, the original incidence included 20 cases (29.0 ％)of chronic myeloid leukemia (CML),14 (20.3 ％) cases of lymphoma,10 (14.5 ％) cases of acute myeloid leukemia (AML),10 (14.5 ％) cases of myelodysplastic syndrome (MDS),6 cases(8.7 ％)of acute lymphoblastic leukemia (ALL),4 cases of multiple myeloma (MM),3 cases of myeloproliferative neoplasms (MPN),2 cases of chronic lymphocytic leukemia (CLL).There was no significant difference of the mygakaryocytes’ count and association of myelofibrosis with it was found (r=0.024,P=0.848). Conclusion Various clinical diseases of blood system may associated with secondary myelofibrosis. Bone marrow biopsy can be used to initial diagnostics of malignant disease of hematological system patients.When cellular examination of bone marrow is dry tap or dilution, which means higher incidence of SMF. Bone marrow biopsy plays an important role in diagnosis of SMF.

OBJECTIVETo explore the distribution features of Chinese medical constitutions in different ages population, thus providing scientific evidence of constitution process theory.

METHODSRecruited were 21 948 cases from a survey of Chinese medical constitutions and health conditions in 9 provinces or municipalities across China (including Jiangsu, Anhui, Gansu, Qinghai, Fujian, Beijing, Jilin, Jiangxi, and Henan) from Dec 2005 to Jan 2007. The body constitution type of individual was diagnosed using discriminant analysis on the basis of Chinese medical constitution questionnaire. By using correspondence analysis, the correlation between the general population, genders, ages, and Chinese medical constitution types was studied.

RESULTSConstitutions of yin-deficiency type, wetness-heat type, qi-depression type, and special diathesis type often occurred in the population ranging 15 -24 years old. Gentleness type mostly occurred in the population ranging 25 -44 years old. During this time period, phlegm-wetness type and wetness-heat type were liable to occur in males, while blood-stasis type was liable to occur in females. Qi-deficiency type and yang-deficiency type were most often seen in those older than 45 years. Phlegm-wetness type and blood-stasis type body constitution were also liable to occur in those older than 45 years.

CONCLUSIONSThe distribution features were different in different Chinese medical constitutions. Different constitution types exist in different genders. Different constitution types exist different ages population.

Objective To investigate the neuroprotection of delayed treatment of thoracic acute spinal cord injury with recombinant human erythropoietin (rhEPO) in rat model of compressive injury. Methods Sixteen adult male Sprague-Dawley rats were randomly divided into two groups: control group (compressive injury group) and experimental group (rhEPO group), In the compressive injury group,the animals recived 0.9% saline treatment at 2 h, day 1 and day 3 after the injury, while in the rhEPO group, rhEPO (3 000 U/kg) was given to rats at 2 h, day 1 and day 3 after the injury. All the rats were observed in 4 days after the injury. The primary outcomes were evaluated by BBB scale, apoptotic index, inflammatory index and electron microscopy. Results Delayed treatment of thoracic acute spinal cord injury with rhEPO could reduce apoptosis, regulate inflammation, improve motor function and promote regeneration of the spinal cord. Conclusion Our study suggests that delayed treatment of thoracic spinal cord compressive injury with rhEPO could exert neuroprotection.

Vertebral artery hypoplasia is a congenital vessel variation. Its incidence is from 1. 9 to 26. 5% . In recent years, studies have shown that vertebral artery hypoplasia may be a potential risk factor for posterior circulation infarction, especialy when it coexists with other cerebrovascular risk factors. Vertebral artery hypoplasia may also cause regional hypoperfusion and complex neurovascular regulation, and it also has a certaln link with migralne.
