Journal of Applied Clinical Pediatrics 1993;0(03):-
Idiopathic thrombocytopenic purpura(ITP) has been confirmed a clinical syndrome because platelets are much destroyed by immunologic mechanism,it is also called immunethrombocytopenic purpura.The pathogenesis of that is very multiplicity,and at present it isn′t understood.This review article is about study progress of B lymphocyte abnormal and the possible pathogenesis of ITP in children.
6.Cause analysis on blindness and low vision of type 2 diabetes in Yangxin county, Hubei
International Eye Science 2015;(8):1419-1421
AIM:To investigate prevalence and causes of blindness and low vision of type 2 diabetes ( T2DM ) in Yangxin county, Hubei province.
METHODS: A total of 8 316 permanent residents, to carry out epidemiological survey of blindness and low vision. Carolina First T2DM patients were in the observation group, the other subjects admitted to the control group. Prevalence and etiology of blind and low vision were compared. Then the data only in the observation group were analyzed.
RESULTS: The rate of blindness and low vision appeared significantly higher, cataracts and retinopathy appeared significantly higher. With the increases of age, prevalence of blindness and low vision appeared significantly increased in the observation group. The rate of low vision was higher in women. Blind and low vision appeared significantly higher in junior high school educations. The above analysis was statistically significant (P<0. 05).
CONCLUSION: The prevalence of blindness and low vision of T2DM patients in our region were significantly higher than the unconsolidated. Blind and low vision in T2DM patients has a certain relationship with age, sex, education.
7.Progress on cervical muscle strength and soft tissue stiffness testing.
China Journal of Orthopaedics and Traumatology 2015;28(8):771-775
Biomechanical evaluation of neck muscles has important significance in the diagnosis and treatment for cervical spondylosis, the neck muscle strength and soft tissue stiffness test is two aspects of biomechanical testing. Isometric muscle testing operation is relatively simple, the cost is lower, which can evaluate the muscle force below grade 3. However, isokinetic muscle strength testing can assess the muscle strength of joint motion in any position. It is hard to distinguish stiffness difference in different soft tissues when the load-displacement curve is used to evaluate the local soft tissue stiffness. Elasticity imaging technique can not only show the elastic differences of different tissues by images, but also quantify the elastic modulus of subcutaneous tissues and muscles respectively. Nevertheless, it is difficult to observe the flexibility of the cervical spine by means of the analysis of the whole neck stiffness. In a word, a variety of test method will conduce not only the biomechanical evaluation of neck muscles, but also making an effective biomechanics mathematical model of neck muscles. Besides, isokinetic muscle testing and the elasticity imaging technology still need further validation and optimization before they are better applied to neck muscles biomechanical testing.

10.Relationship between Glucose-6-Phosphate Dehydrogenase Deficiency and Viral Hepatitis in Guangxi Area
Journal of Applied Clinical Pediatrics 2006;0(19):-
Objective To study the glucose-6-phosphate dehydrogenase(G6PD)genotypes in the children of viral hepatitis with G6PD deficiency and investigate the relationship between G6PD deficiency and viral hepatitis.Method DNA samples of 18 children with viral hepatitis/ G6PD deficiency were studied for the 3 common mutations by using the natural primers or mismatched primers mediated PCR followed by restriction enzyme analysis and their clinical manifestation was analyzed.Results Among 18 cases,8 cases were G1388A,and 4 cases were G1376T,and 1 case was A95G.The 3 mutations of G1388A,G1376T and A95G added up to 72.22%.There were no significant difference between the patients with viral hepatitis/ G6PD deficiency and the children only with G6PD deficiency.The incidence rates of acute hemolysis and acute renal failure in the viral hepatitis/G6PD deficiency patients were higher than those in children with G6PD deficiency only.Conclusions It is supposed that the G6PD deficiency is primary in the patients of viral hepatitis with G6PD deficiency.The children of viral hepatitis with G6PD deficiency have more severe pathogenetic conditions and more complications than the children with G6PD deficiency only.
