1.Progress in the role of steroids in Kawasaki disease therapy
International Journal of Pediatrics 2013;40(4):367-370
Kawasaki disease(KD) is the most common reason for acquired heart disease in children,which is closely related to autoimmune response and the release of cytokines in vascular endothelial cells.Steroids are strongly effective in countering inflammation as well as immune response.In the time of being,it has become a hot spot that steroids play an important role in the initial treatment for acute KD and for incomplete and refractory KD.
2.Kawasaki disease and allergic diseases
International Journal of Pediatrics 2012;39(3):234-236
Kawasaki disease (KD) is one of the most common causes of acquired heart disase in children,the development of which is closely related to the allergic diseases.Recent studies have manifested that the incidence of allergic diseases in children with KD is far higher than that in those children without KD.Meanwhile,the morbidity of KD in allergic children is significantly higher than that in those who do not have family medical history of allergic diseases.By far,the mechanisms causing interaction between KD and allergic diseases still remain unclear.Possible mechanisms include IgE-meditated immune response,release of large quantity of cytokines and inflammatory meditators as well as atopic family history.
4.The application of low dose CT with automatic tube current modulation in the diagnosis of pneumoconiosis
Chinese Journal of Postgraduates of Medicine 2014;37(9):13-15
Objective To explore the feasibility and application value of low dose CT with automatic tube current modulation (ATCM) in the diagnosis of pneumoconiosis.Methods Forty-five patients with pneumoconiosis confirmed by the occupational agency underwent standard dose CT scanning with a fixed tube current of 150 mA and low dose CT scanning with ATCM (50-200 mA) with noise index (NI) of 14.The CT dose index volume (CTDIvol) and dose length product (DLP) under the different scanning condition were recorded.The image quality,specific image manifestations of pneumoconiosis (shadow size,shadow concentration,pneumoconiosis stages) were reviewed in double-blind methods by two radiologists,and the statistical analysis was performed.Results CT characteristics of pneumoconiosis could be detected efficiently with low dose CT scanning with ATCM.There were no significant differences in showing the shadow size,shadow concentration,pneumoconiosis stages and the image quality between the two groups (P>0.05).The CTDIvol and DLP of standard dose CT scanning were 13.53 mGy and (337.13 ± 13.53) mGy/cm respectively,and CTDIvol and DLP of low dose CT scanning with ATCM were (7.39 ± 0.45) mGy and (188.78 ± 1.80) mGy/cm,there were statistical differences (P < 0.05).Conclusions Low dose CT scanning with ATCM can reflect the characteristics of pneumoconiosis,and it also can significantly reduce the radiation dose with diagnostic acceptability of the image quality.So low dose CT scanning with ATCM can replace the standard dose CT scan in diagnosing and screening of the pneumoconiosis.
5.A STUDY ON THE HUMAN INTRACEREBRAL SEGMENTS OF THE CENTRAL BRANCH OF THE MIDDLE CEREBRAL ARTERY
Acta Anatomica Sinica 1953;0(01):-
The origin, diameter, arrangement pattern, distribution and microvascular architecture of the intracerebral segments(IS) of the central branches of the middle cerebral artery(MCA) were examined and pictured in 27(10 infants, 5 newborns, 12 fetuses) unfixed brains under stereoscopic microscope and scanning electron microscope. 1. The extracerebral segments(ES) of the central branches run toward the anterior perforated substance in S-shaped curves. The IS arise from ES or their collateral branches. They form the fan-shaped appearance in rostromedial and caudolateral state after entering brain. 2. The IS give rise collateral branches in right or acute angles, and they are of two kinds: the longitudinal and the transverse branches. The mean diameter of the IS in original site is 0.21?0.18mm for the medial group; 0.36?1 0.21mm for the lateral group. 3. The medial group mainly distribute in the rostal part of the internal capsule and basal nucleus; the lateral group mainly distribute in the caudal part. 4. Some circular impressions of the precaillary sphincters were observed at the beginning of precapillary arteriole and capillary, converging point of tributary branches of venule. The relationship between the IS of the central branches and the hemodynamics was discussed.
6.Association between tracheal epitheliums and bronchitis obliterans following lung transplantation
Chinese Journal of Tissue Engineering Research 2010;14(5):911-914
Lung transplantation is the only effective treatment for final stage pneumonopathy. However, bronchitis obliterans, as the main of complication, can prevent the long term survival after lung transplantation. Tracheal epithelium cell is the main target organ of the tardive reject reaction. This paper briefly explains the immunologic mechanism regarding the development of bronchitis obliterans, and the role of tracheal epithelium cell in the study, with aim of exploring the initial relationship between tracheal epithelium cell and bronchitis obliterans, and to find a method to solve the long-term survival of lung transplantation.
7.Application of magnetic resonance imaging diffusion weighted imaging in lung cancer
Journal of International Oncology 2011;38(10):771-774
Magnetic resonance imaging diffusion weighted imaging (DWI) as a non-radiation and noninvasive examination method,has great help in diagnosis and staging of lung cancer,and the apparent diffusion coefficient (ADC) determination has demonstrated clinical application value in the therapeutic assessment.As an essential complement of CT,MRI-CT imaging infusion improves the accuracy of the target volume sketching in the radiotherapy of lung cancer.
8.Clinical Analysis of 124 Children with Henoch-Sch(o)nlein Purpura
Journal of China Medical University 2010;(1):58-60
Objective To study the clinical characteristics of Henoch-Sch(o)nlein purpura (HSP) in children.Methods We retrospectively analyzed the clinical data of 124 children with HSP.Results Among these 124 children,54.84% of the children presented upper respiratory tract infection before the onset of HSP.The purpura recurred in 30 of 47 children with Henoch-Sch(o)nlein purpura nephritis and in 22 of 77 children without Henoch-Schonlein purpura nephritis,respectively (P<0.05).The incidence of Henoch-Sch(o)nlein purpura nephritis was significantly higher in children who had purpura,gastrointestinal symptoms,and joint symptoms simultaneously than in those only with purpura (P<0.05).The elevated levels of IgA and C reactive protein were found in 67.35% and 39.39% of the children,respectively.Conclusion The most important predisposing factor of HSP is upper respiratory tract infection.The children with recurrence of purpura or those who have purpura,gastrointestinal symptoms,and joint symptoms simultaneously are more likely to present renal damage.

International Journal of Traditional Chinese Medicine 2012;(12):1078-1080
Objective To observe the influences of Yiqi-Humo recipe,A traditional Chinese prescription,on mucosa repair after endoscopic mucosal resction (EMR) and (or) endoscopic submucoal dissection (ESD).Methods 32 patients,who received EMR or ESD,were randomly recurited into a control group with 14 patients (omeprazole) and a experiment group with 18 patients (Yiqi-Humo recipe + omeprazole).Patients of both groups received treatment for a period of 4 weeks.Follow-up endoscopy was performed at 1 and 4 weeks after EMR or ESD,the index of symptom and mucosa signs were evaluated before and after the operation.Results At the 4 weeks after the procedure,the index of pain,pantothenic acid,anorexia,burning sensation in the experiment group [(0± 0.00)、(0± 0.00)、(2 ± 0.11)、(1 ± 0.06)] were lower than those in the control group [(12±0.86)、(6±0.43)、(15 ± 1.07)、(14± 1.00),P<0.01].The index of hyperemia and edema of the experiment group [(3 ± 0.17)、(3 ± 0.17)] were less than those of the control group [(16± 1.14)、(15 ± 1.07),P< 0.01].Conclusion The prescription of Yiqi-Humo recipe promoted mucosa repair significantly after EMR or ESD.
