1.Research progress of primary extramedullary plasmacytoma
Journal of International Oncology 2016;43(2):138-140
Extramedullary plasmacytoma (EMP) is a rare tumor characterized by proliferation of monoclonal plasma cells,often occurs in the head and neck,followed by gastrointestinal and skin.Diagnosis is based on biopsy,which is the only accurate and reliable method.EMP is needed to discriminate with similar diseases.Radiotherapy is the preferred treatment method of EMP,because it has a higher radiation sensitivity.Sometime we can choose comprehensive treatment because of illness need.Hematopoietic stem cell transplantation is not as the preferred treatment option because of transplant rejection.
2.Influence of erythropoietin therapy with oral iron supplementation on red blood cell distribution width in chronic heart failure patients with anemia
Chinese Journal of Primary Medicine and Pharmacy 2015;(18):2777-2780
Objective To analyze the effect of erythropoietin therapy with oral iron supplementation on red blood cell distribution width (RDW)in chronic heart failure patients with anemia.Methods 148 patients of chronic heart failure with anemia from September 2014 to March 2015 in our hospital were included and randomly divided into two groups with the random number table,with 74 cases in each group.The control group were treated with convention-al anti heart failure therapy,the treatment group were treated with erythropoietin and oral iron supplementation on the basis of routine treatment for four weeks.RDW was tested by automatic five classification blood analyzer.The correla-tion between RDW and other detection indexes was analyzed.Results The levels of RDW in the treatment group were significantly lower than those of the control group[(13.08 ±0.792)vs (14.32 ±0.864),t =-8.974,P <0.01].Before treatment,bivariate analysis in the treatment group showed that RDW had positive correlation with NT-proBNP and high -sensitivity C -relative protein (hs -CRP)(r =0.783,P <0.01;r =0.870,P <0.01),but negative correlation with serum creatinine (Cr)and hemoglobin (r =-0.338,P <0.01;r =-0.743,P <0.01).Af-ter treatment,bivariate correlations analysis in the treatment group showed that the difference of RDW was positive correlation with the difference of NT -proBNP,high -sensitivity C -relative protein (hs -CRP)(r =0.783,P <0.01;r =0.680,P <0.01),but negative correlation with the difference of hemoglobin(r =-0.459,P <0.01),and no correlation with the others (Cr,UA,LDL,TC,TG and LVEF).Conclusion On the basis of conventional anti heart failure treatment,erythropoietin therapy with oral iron supplementation against anemia could improve heart func-tion of CHF and decrease the levels of RDW.RDW may be served as one of observing indexes of the worsening and effect judgment in chronic heart failure patients with anemia.
3.Advances in Research on Hepatitis B Virus DNA Integration
Virologica Sinica 2008;23(2):93-99
Since HBV DNA integration was discovered for the first time in 1980, various methods have been used to detect and study it, such as Southern Blot, in situ hybridization, polymerase chain reaction and so on. HBV DNA integration is thought to be random on the whole although some hot spots of integration were described by some researchers, one of which might be the repetitive sequences of the genomic DNA. Besides, DNA damage, especially double-strand breaks could promote HBV DNA integration into host genome. HBV DNA integration into cells may damage the stability of the genome, cause DNA rearrangement, promote DNA deletion and induce the formation of HCC.

Chinese Journal of Radiology 1999;0(10):-
Objective To investigate the applicative value in stages of pre-infarction period using dynamic perfusion CT. Methods Dynamic perfusion CT was performed in 32 cases of cerebral hypoperfusion. The ratios of side-to-side were measured at hypoperfusion areas in the regional cerebral ischemia. The stages of pre-infarction period were made as the following: (Ⅰ 1) TTP was delayed, MTT, rCBF and rCBV were normal; (Ⅰ 2) TTP and MTT were delayed, rCBF was normal, and rCBV was normal or slightly increased; (Ⅱ 1) TTP and MTT were delayed, rCBF was decreased, and rCBV was normal or slightly decreased; (Ⅱ 2) TTP and MTT were delayed, rCBF and rCBV were decreased. Results There were 4 cases in stage Ⅰ 1. Regional hypoperfusion was revealed only by TTP map. The mean ratios of rCBF, rCBV, MTT, and TTP were 1.00, 1.00, 1.00, and 1.30, respectively. In stage Ⅰ 2, the areas of delayed TTP and MTT were found in all 13 cases. The rCBF and rCBV maps appeared normal in 8 cases. Another 5 cases showed normal rCBF and slightly increased rCBV areas. The mean ratios of rCBF, rCBV, MTT, and TTP were 1.00, 1.03, 1.38, and 1.30, respectively. In stage Ⅱ 1, the areas of delayed TTP and MTT were revealed in all 8 cases. The depiction of decreased rCBF was also found in 8 cases. The areas of decreased rCBV were showed in 5 cases, and normal rCBV maps were revealed in 3. The mean ratios of rCBF, rCBV, MTT, and TTP were 0.56, 0.94, 1.49, and 1.47, respectively. In stage Ⅱ 2, the areas of delayed TTP and MTT were revealed in all 4 cases, in whom depiction of decreased rCBF and rCBV was also found. The mean ratios of rCBF, rCBV, MTT, and TTP were 0.42, 0.59, 1.57, and 1.55, respectively. Conclusion CT perfusion imaging and its parameters' analysis may play an increasing role to delineate the depiction of cerebral hypoperfusion in pre-infarction period. Analyzing the relationship of rCBF, rCBV, MTT, and TTP is very helpful to know the status of the capillary vessels in regional cerebral hypoperfusion area and to provide functional information with our stages of pre-infarction period.

Shanghai Journal of Acupuncture and Moxibustion 2017;36(8):910-913
Objective To observe the clinical efficacy of acupuncture plus rehabilitation training in improving post-stroke dysphagia. Method A total of 60 patients with post-stroke dysphagia were randomized into a treatment group and a control group, 30 cases in each group. The two groups were intervened by basic treatment of internal medicine and swallowing rehabilitation training, and the treatment group was additionally given acupuncture treatment. The Standardized Swallowing Assessment (SSA), water swallowing test and Swallowing Quality of Life Questionnaire (SWAL-QOL) were evaluated in the two groups before and after the treatment. Result After the treatment, the SSA scores in the two groups were significantly decreased compared to those before the treatment (P<0.01), and the SWAL-QOL scores were significantly increased compared to those before the treatment (P<0.01); the SSA score in the treatment group was significantly lower than that in the control group (P<0.01), and the SWAL-QOL score was significantly higher than that in the control group (P<0.05). The water swallowing test classification after the treatment was significantly superior to that before the treatment in the treatment group (P<0.01), and there was a significant difference compared to that in the control group (P<0.05). Conclusion Acupuncture plus rehabilitation training can obviously improve the swallowing function of patients with post-stroke dysphagia, and the clinical efficacy was superior to single rehabilitation training.
6.Personal computer aided mapping and measurement of cerebral perfusion with dynamic CT
Chinese Journal of Radiology 2001;0(01):-
Objective To intruduce a method of making cerebral perfusion mapping and measurement using dynamic CT with a personal computer. Methods We generated the cerebral perfusion mapping and measurement from a series dynamic CT images with a personal computer. The theoretic basis of our technique is central volume principle. The application software was made using visual C++ language with Windows 98 platform. Results This method was applied to a case of transient ischemic attack (TIA). The cerebral perfusion mapping contributed to display the abnormal area of ischemia, which showed as normal imaging appearances in routine CT and MR images. Conclusion Personal computer aided mapping and measurement of cerebral perfusion with dynamic CT is a simple and accessible technique for delineating the hemodynamic response, including abnormal regional cerebral blood flow, blood volume, mean transit time, and time to peak in cases of hyperacute ischemic stroke which was viewed as normal imaging findings in routine CT and MR examination. This method is more suitable to examine emergency cases than MR perfusion imaging and may be used in any facility where CT scanner and personal computer are available.
