1.Intravascular malignant lymphomatosis and Asian variant
Journal of Medical Postgraduates 2004;0(01):-
Because absence of lymphoadenopathy, and often associated with haemophagocytic syndrome, the intravascular malignant lymphoma(IVL) is easy mistaken as malignant histiocytosis or connective tissue disease or vasculitis, the diagnosis was difficult while patients were alive. The clinical course of this disorder (IVL)was aggressive and carried a poor prognosis. The cases of this disorder are not too rare to be seen in our country. To enhance one′s ability to differentiate disorder in unknown fever diseases are extremely necessary.
2.Clinical significance of ADAMTS13 activity in thrombotic thrombocytopenic purpura patients
Journal of Medical Postgraduates 2003;0(03):-
A deficient of plasma VW factor-cleaving protease (ADAMTS13) and appearance of unusually large multimers induced platelets aggregation in capillaries and arterioles. It was critical pathogenesis of thrombotic thrombocytopenia purpura (TTP). ADAMTS13 activity has been measured over 1000patients of TTP and hemolysis uremia syndrome (HUS) since 1997. Diagnostic sensitivity and specificity,as well as clinical significance of ADAMTS13 deficiency for TTP patients were evaluated,and synthetical diagnosis basis of TTP were raised.
3.Optimization in the construction of the hospital PACS
China Medical Equipment 2014;(10):56-58
Objective:To Integrated PACS and hospital information systems (HIS), and improve the efficiency of PACS, and improve the user experience. Methods:Base on deeply analysis of existing problems in system application, using process optimization, software optimization, and hardware upgrades manner optimize PACS. Results: PACS and HIS realized Integrated, improving the overall performance of the PACS. Enhance the user experience and expand the application scope of PACS. Conclusion: Deeply analysis of existing problems should be done before optimizing the system. Process optimization, software environment optimization should be considered as the most important and upgrading and replacement of the hardware as the secondary.
4.Effects of intravitreal injection of Lucentis for anterior segment neovascularization indeced by central retinal vein occlusion
International Eye Science 2016;16(8):1573-1575
Abstract?AIM:To investigate the therapeutic effect of Lucentis in the treatment of anterior segment neovascularization ( ASNV ) induced by central retinal vein occlusion ( CRVO) .?METHODS: This was a retrospective case series study for patients with ASNV secondary to CRVO from January 2013 to December 2014 and treated with intravitreal injection of lucentis. Best visual acuity ( BCVA ) , intraocular pressure ( IOP ) , iris examination and gonioscopy, and if necessary, fluorescein angiography and optical coherence tomography, were recorded.The follow-up time was 6-13mo, the average was 9.1 ± 2.9mo.?RESULTS: Eighteen patients ( 18 eyes ) were treated with intravitreal injection of lucentis;15 patients (15 eyes) of the 18 were treated with panretinal photocoagulation;the other 3 patients 3 eyes were not received the photocoagulation because of vitreous opacity. One patient was treated with glaucoma valve implantation.Six patients with only neovascularization and without glaucoma were improved in visual acuity whose intraocular pressure was controlled after combined treatment.Of the patients with neovascular glaucoma ( n=12 ) , after intravitreal injection of lucentis and panretinal photocoagulation, the IOP was controlled in 4 patients (4 eyes);the IOP of another 7 cases reduced but glaucoma drugs were still needed.One patient ( 1 eye ) received glaucoma valve implantation because of bad control on IOP with worse vision after implantation.The rubeosis disappeared in all patients.?CONCLUSION:Intravitreal injection of lucentis can stop neovascularization and help to control IOP.In the early stage without neovascular glaucoma, lucentis has better effects, which means early detection and intervention are important.
5.Study Progress of Infantile Spasms in Molecular Genetics
Journal of Applied Clinical Pediatrics 1994;0(04):-
Infantile spasms is a type of refractory epilepsy syndrome.This epilepsy syndrome is characterized by special tonic spasms,a peculiar set of electroencephalographic findings termed hypsarrhythmia,and arrest of psychomotor development in most patients.The etiology is not clearly understood.Recently,mutations of the arista less related homeobox gene(ARX),cyclin-dependent kinase-like 5(CDKL5)/se-rine/threonine kinase 9 gene(STK9),membrane associated guanylate kinase 2 gene(MAGI2),et al,and abnormal chromosome had been found to be responsible for infantile spasms.In this review,progress of infantile spasms in molecular genetics are discussed.

Objective To analyse the treatment results of proximal humerus fracture in over sixty-years-old patients. Methods From January 1999 to January 2003, 32 cases suffered from fractures of the proximal humerus were studied, which involved 13 males (mean age 73.2 years, range 60-88 years), and 19 females (mean age 75.5 years, range 60-94 years). There were 22 cases (65.7%) with two-part fractures, among them, 68.1% was surgical neck fracture. 3 cases with two-part and 1 with three-part fracture were treated conservatively because of either their poor health condition or their refusal to operation. The other 28 patients were operated. According to the Neer classification, through the statistic and analysis for the method and outcome, all the cases were evaluated in term of the American UCLA scale system. Results 25 of the 28 operated patients were available at the final follow-up, the mean period was 1.5 years with a range of 1 to 3 years. All the fractures had united. 5 patients with healing time more than 3 months were those fractures classified as three or four-part, which needed the tension-band fixation. All the patients complained with joint stiffness in different degree, 6 of the patients with three or four-part remained with sustaining shoulder contracture. According to the UCLA, the good-excellent rate was 81.2% in the two-part fractures, and only 33.3% in the three or four-part fractures. Conclusion The treatment methods of proximal humerus fracture in aged patients should be selected according to individual condition. The tension band fixation is a good choice for those who can't accept the joint replacement, though the outcome after the four-part fractures fixation is less satisfactory. Joint contracture and humeral head necrosis may be the common complications among the patients rated as three or four-part fractures. After operation, early and complete rehabilitation are closely related to the treatment results.

Purpose:To compare the sensitivity and specificity of urinary cytokeratin test with voided urine cytology in detection of bladder cancer and to evaluate their clinical values. Methods:For 136 patients suspected to have bladder cancer urinary concentrations cytokeratin 8 and 18 and cytology were conducted in the same voided urine samples. Of them 87 patients with bladder transitional cell carcinoma were confirmed histologically The sensitivity and specificity of urinary cytokeratin and urine cytology were analyzed. 49 patients without bladder cancer were selected as control.Results:The overall sensitivity and specificity of urinary cytokeratin test were 70.1% and 73.3%,respctively ,those of urine cytology were (42.5%) and 83.7%, respectively, there was no significant difference between the specificity of urine cytology and that of urinary cytokeratin test ;however, urinary cytokeratin was significantly more sensitive than urine cytology in detection of any stages and grades of bladder cancer (P
