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.

Comparing the patients with type 2 diabetes and the control and using the animal models,the researchers have found some disease related proteins and the marks for disease detection.They have set some new detection methods and give us a special view into type 2 diabetes.We do some primary discussions about recent studies and future development directions in the proteomics study of type 2 diabetes in this article.

Objective:To investigate the effects of Adp53 and F56 on the growth and lung metastasis of breast cancer.Methods:The BICR-H1 cells were inoculated into the mammary fatty pad of BALB/C nude mice and NOD/SCID mice to establish breast cancer model.Then the nude mice with xenograft tumor were randomized into group Adp53+F56,Adp53,F56 and control.The NOD/SCID mice with xenograft tumor were randomized into group Adp53+F56,Adp53,F56,Adlacz and control.They were theated for 3 weeks according to the plan,diversity of the volume and histopathology of xenograft tumor of nude mice was observed and the expressions of p53 and VEGF gene,and microvessel density(MVD)were detected by immunohistochemistry.Lung metastasis of breast cancer in NOD/SCID mice was observed.Results:(1)Intratumoral injections of Adp53,F56,and their combination resulted in an inhibition on the growth of xenograft tumor of BICR-H1 cells.The ultimate relative growth volumes of groups Adp53+F56,Adp53,F56 and control were 2.47,4.37,4.69 and 12.49 respectively.(2)After treatment,P53 positive rate of group Adp53+F56,Adp53 increased 9.4%,6.3% than before respectively,but compared with control group,the difference is not significant(P=0.693);VEGF protein of group Adp53+F56,Adp53 and F56 decreased 21.9%,9.4% and 3.1% than before respectively,but compared with control group,the difference was not significant(P=0.284).Necrosis and decrease of vessel in the tumor and morphological change of endothelium were observed under light microscope in the groups Adp53+F56,Adp53 and F56.MVD estimated by FⅧ-RA staining of group Adp53+F56,Adp53 and F56 were 14.50?2.54,16.28?3.44 and 18.06?7.66,compared with control group(24.93?6.53),the difference is significant(P=0.000).(3)The average number of lung metastasis of NOD/SCID mice in group Adp53+F56,Adp53 and F56 were 1.143?0.378,2.750?0.886 and 3.375?0.518 respectively,lower than Adlacz group(5.000?0.816)and control group(5.670?0.817)obviously(P=0.000).Conclusion:Adp53 combined with F56 can greatly inhibit growth and matastasis of breast cancer in vivo.The mechanism of anti-tumor effects of Adp53 and F56 may be related to the anti-angiogenesis effect on malignant tumor through inhibiting the expression and activity of VEGF.
