Objective To analyse the clinicopathological features of primary small intestine lymphoma(PSIL), and explore the relationship between clinical stage,histological findings,therapeutic modality and prognosis. Methods The clinical data of 34 cases of PSIL were collected,the pathohistological features and results of immunohistochemical examinations were obtained,and the follow-up findings were adopted for comprehensive analysis. Results Among these 34 cases of PSIL,abdominal pain or discomfort,gastrointestinal bleeding and abdominal mass were the predominant symptoms.PSIL mainly involved ileum,especially the bottom of ileum and ileocecal area.Among the 26 patients with follow-up for more than one year,the 1-year survival rate was significantly higher in patients without tumor perforation than those with tumor perforation(76.2% vs 20.0%)(P

Objective To investigate the MRI and echocardiography manifestations of noncompaction of ventricular myocardium(NVM)and assess the role of MRI in the diagnosis of NVM by comparing it with echocardiography.Methods Fourteen cases of NVM diagnosed by echocardiography were examined with MRI,including scanning of black-blood sequences,double inversion recovery fast spin echo (DIRFSE)and triple inversion recovery fast spin echo(TIRFSE),and white blood sequence:fast imaging employ steady state acquisition(FIESTA).Scanning plane includes short axis view,four-chamber view and long axis view.Results Both MRI and echocardiography displayed involvement of left ventricles in thirteen cases and involvement of double ventricles in one case.Apexes of heart and the intermedius are commonly affected.MRI showed 54 segments and echocardiography showed 53 segments affected,and there is no significant difference between the capability of MRI and echocardiography(P=1.000).The affected myocardium consisted of two layers:subendoeardial noncompacted myocardium and epicardial compacted myocardium,and the ratio measurement of N/C by MRI was 3.37?0.89 and it was 3.19?0.82 by echocardiography.Noncompacted myocardium was characterized by prominent and excessive myocardial trabeculations and deep intratrabecular recesses,in which the blood flow was communicated with the ventricle.One case was complicated with ventricular aneurysm,and coronary arteriography was performed with unremarkable findings.One case underwent heart transplantation because of progressive heart failure, Gross findings demonstrated prominent muscular trabeculations with deep intratrabecular recesses,which coincided well with MRI findings.Conclusion The MRI manifestation of NVM is characteristic,and MRI with multiple series and planes is helpful in the diagnose of NVM.Compared with echoeardiography,MRI could display the pathological cardiac muscle more clearly,because of its high soft-tissue resolution and spatial resolution.

Objective To observe the Th17, IL-17 and Tr cells equilibrium state as well as their changes of HIV infected or AIDS suffered patients in one-year HAART treatment. Methods Select 33 HIV/AIDS patients received HAART treatment while 33 healthy volunteers as controls. Flow cytometry was used to analyze Th17 and Tr cells in venous blood at the time of pre-therapy, 6th, 12th month when IL-17 levels in serum are tested by ELISA. Results The ratio of Th17 cells in CD4 cells in HIV/AIDS patients and volunteers were (1.20±0.37)%, (2.50±1.03)%, (3.70±1.56)%, (4.70±1.43)%, respectively; The ratio of Tr cells were (9.16±3.33)%, (7.19±2.91)%, (5.53±1.88)%, (4.43±0.97)%, respectively; The levels of IL-17 in serum were (5.3±2.5) pg/ml, (7.7±2.4) pg/ml, (10.4±3.1) pg/ml, (17.7±6.6) pg/ml respectively. The Th17 cells' level was positively correlative with the amount of CD4 cells, negatively correlate with the count of viral load. However, the Tr cells level is positively correlative with the count of viral load, negatively relate to the quantity of CD4 cells. Conclusion HIV could make IL-17, Th17 cells and Tr cells lost their balance, but the immune equilibrium state may gradually recover after HAART treatment. Which indicates the IL-17, Th17 cells and Treg cells may play an important role in the pathogenesis of AIDS, and they are likely to be the effective indexes to observe the progress of AIDS and the treatment effect of highly active antiretroviral therapy(HAART).

OBJECTIVE To explore the effect of blood-activating and organ-purging formula in vivo of intestinal mucosal barrier after surgery in peritoneal adhesion.METHODS 60 male SD rats were randomly divided into control group,model group and Huoxue Tongfu Decoction group.Besides the control group,the rest of the rats were established with grater method,and the same dose of drugs were given at 3,6,12,24 h after operation.The blood and tissue samples were taken after 48 h.TNF-αlevels in plasma were determined by ELISA,sIgA in intestinal mucosa was detected by immunohistochemical method and the number of content of CD4 cells,lymphocytes apoptosis of intestinal mucosa were detected by TUNEL.RESULTS Compared with the control group,the plasma levels of TNF-αin the model group of 6,12,24 h showed significant difference(P <0.05～0.01),intestinal mucosa under lymphocyte were apoptosis significantly(P <0.01),12 h and 24 h secretion IgA significantly increased(P<0.05),and the model group 12 h,24 h and 3 h,6 h,submucous lymphocyte apoptosis decreased close to the level of control group,model group 3 h CD4 in intestinal mucosa cell number decreased significantly(P <0.01),there was no significant difference in the number of CD4 cells when three groups at 6 h,12 h and 24 h(P>0.05).Prescription in 3 h after operation can significantly reduce the levels of TNF-αin plasma of model rats increased number of intestinal mucosae,the content of IgA and CD4 cells decreased,submucous lymphocyte apoptosis.CONCLUSION Blood-activating and organ-purging formula group can reduce the blood level of TNF-alpha and submucous lymphocyte apoptosis,increase the number of intestinal mucosals content of IgA and CD4 cells,improving local immunity,inhibiting the inflammatory reaction.

OBJECTIVETo identify the distribution and differentiation of ABL kinase domain mutation in the Chinese Han nationality imatinib resistant chronic myeloid leukemia (CML) and Philadelphia chromosome-positive acute lymphoblastic leukemia (Ph(+)ALL).

METHODSBone marrow or peripheral blood samples of 112 imatinib resistant CML patients and 21 Ph(+)ALL patients were obtained from the first affiliated hospital of Soochow university according to local law. Total RNA was extracted from the mononuclear cells using a TRIzol reagent. ABL kinase domain (KD) mutation was detected by direct sequencing.

RESULTSOf the 112 imatinib resistant CML patients, 54.46%(61 cases) had ABL KD mutation. Twenty-three mutants were identified in 20 amino acid sites and 23.21% (26 cases) ABL KD mutations were in P-loop region. ABL KD mutations were also detected in 71.43% (15 cases) imatinib resistant Ph(+)ALL patients, with 10 mutations in 8 amino acid sites. The most frequent mutation was T315I (28.57%), followed by E255K/V (19.05%) and Y253F/H (14.29%). The frequency of T315I was much higher in imatinib resistant Ph(+) ALL than that in imatinib resistant CML (P = 0.001). Ph(+)ALL with additional chromosomal aberrations also had a higher rate of ABL KD mutation than that of CML (P = 0.010). Ph(+)ALL gained ABL KD mutation faster than CML (P < 0.010).

CONCLUSIONChinese imatinib resistant CML and Ph(+)ALL patients had different characteristics in ABL KD mutation. The rate of ABL KD mutation in Ph(+)ALL with additional chromosomal aberrations was much higher than that of CML with additional chromosomal aberrations.

OBJECTIVETo observe the effect of three Chinese medical formulae (Zhifei Mixture I , Zhfei Mixture II, and Zhifei Mixture II) on main and secondary symptoms and signs of children with Totally 70 mycoplasma pneumonia in treating three types of children mycoplasma pneumonia.

METHODSchildren with mycoplasma pneumonia were assigned to the control group (38 cases) and the treatment group (32 case). All patients were intravenously injected with Azithromycin and took Ambroxol Hydrochloride and Clenbuterol Hydrochloride Oral Solution. Those in the treatment group additionally took Zhifei Mixture I , Zhfei Mixture II, and Zhifei Mixture Ill by syndrome typing. Their main and secondary symptoms and signs were observed before and after treatment (main symptoms and signs covered fever, cough, abundant sputum, short breath, and anoxia; secondary symptoms and signs covered aversion to cold, heart rate, facial complexion, spirit, appetite, and sweating).

RESULTSSeven patients were lost in this study. Compared with before treatment in the same group, scores for main and secondary symptoms and signs decreased in the treatment group (P <0.01). The therapeutic effect on fever and cough was obviously better in the control group (P <0.01). The main and secondary symptoms and signs were more obviously improved in the treatment group than in the control group (P <0.01). Commpared with the control group, scores for main and secondary symptoms and signs decreased more in the treatment group (P <0.01). Patients' main and secondary symptoms and signs were more obviously improved (P <0.05).

CONCLUSIONSZhifei Mixture combined Western drugs could significantly improve main and secondary symptoms and signs of mycoplasma pneumonia children patients. Its efficacy was superior to that of using Western medicine alone.
