Objective Video-assisted thoracoscopic surgery is widely used in clinical practice,due to the characteristics of minimal invasion,quick recovery,low incidence of postoperative chest pain and the same effect of lobectomy as thoracotomy.However,the surgical itself has a certain degree of difficulty,and due to the effect of lymph node,intraoperative blood loss,pleural adhesions,conversion to thoracotomy surgery is needed in some cases. Understanding the risk factors of conversion to thoracotomy can help thoracic surgeons figure out the right time to operate the surgery.

Caused by Helminthosporium carposaprum, tomato brown lea f spot was a serious disease in green house in Henan Province. The condition for promoting sporulation of fungi were tested in this paper. The results showed th at the number of sporulation were different on the different medium,the fungi c ould sporulate a lot on the PDA+tomato leaf and Czapek medium, but V8、PSA and t omato juice restrained sporulation.The best carbon source and nitrogen source f or the fungi promoting sporulation were fructose and ammonium chloride respectiv ely,mannitol and Peptone ammonium sulfate restrained sporulation. Light and ult raviolet radiation were in favor of sporulation , ultraviolet radiation irradiat ing for 60～80min promoted sporulation. The fungi were promoted sporulation on the condition of lower or higher temperature and alkalescence,which 15℃o r 30℃,pH 8～9.

OBJECTIVETo analyze clinical features, therapeutic effects and prognostic factors of patients with mantle cell lymphoma (MCL).

METHODSClinical data of 37 MCL patients hospitalized in our hospital from January 2000 to March 2010 were retrospectively analyzed.

RESULTSThe median age was 62, with a male predominance. 97.30% of the patients were in Ann Arbor stage III ∼ IV, 54.05% with B symptoms, 64.86% with bone marrow involvement, 29.73% with splenomegaly, 24.32% with lymphocytosis and 51.35% with elevated LDH. Ki-67 was detected in 22 cases, and patients with Ki-67 ≤ 40% accounted for 68.18%. Of 37 cases, the overall response rate (ORR) of rituximab combined with chemotherapy was 92.31%, being higher than those of CHOP (46.15%) and CHOP + IFN (42.86%) regimens. There were statistical differences in the 3-year progression-free survival (PFS) and overall survival (OS) between rituximab + chemotherapy and CHOP or CHOP + interferon regimens (P < 0.05, respectively). Splenomegaly, elevated WBC, lymphocytosis and Ki-67 > 40% were identified as adverse prognostic factors.

CONCLUSIONMost patients with MCL were older adults, with a male predominance and usually had bone marrow involvement and poor prognosis. Rituximab combined with chemotherapy could improve ORR and OS of MCL.

OBJECTIVETo investigate the alternation and significance of CD4(+)CD45RA(+) T cells and CD4(+)CD45RO(+) T cells in peripheral blood of colorectal cancer patients.

METHODSThe expression of CD4(+) T cells, CD4(+)CD45RA(+) T cells and CD4(+)CD45RO(+) T cells in peripheral blood of 60 colorectal cancer patients were detected with flow cytometry pre-operatively and 1, 3 months post-operatively, compared with those of 10 healthy persons.

RESULTSCD4(+) T cells expression of colorectal cancer patients was the same as the healthy persons. The proportion of CD4(+)CD45RO(+) T cells of colorectal cancer patients was higher, which descended post-operatively, especially in Dukes A and B patients, while CD4(+)CD45RA(+) T cells showed the opposite findings.

CONCLUSIONCD4(+)CD45RA(+) T cells and CD4(+)CD45RO(+) T cells, playing an important immune effect in colorectal cancer patients, is closely related to stage and prognosis.

Aim The effect of tetrandrine on TGF-?1 mRNA expression in glomerulosclerosis rat was observed. Methods The rats were randomly divided into four groups, such as the normal control group (sham operative rat), glomerulosclerosis model group,tetrandrine group and amlodipine group. The expression of TGF-?1 mRNA was analyzed by Northern blot hybridization. Results The expressions of TGF-?1 mRNA in two treating groups were much lower than untreated model group. There were no difference between these two treating groups. Conclusion Tetrandrine can decrease the expression of TGF-?1 mRNA in glomerulosclerosis rat induced by unilateral renctomy plus adriamycin.

Objective To explore the activated brain region of acute epilepsy in cat model induced by pentylenetetrazol(FFZ)with manganese enhanced-functional MR imaging(ME-fMRI),and evaluate the application of ME-fMRI on localization of the activated brain.Methods Forty cats were divided into 4 groups by random number table method as epileptic A and B groups as well as control A and B groups. Cats of epileptic groups were injected with PTZ(55 mg/kg)intramuscularly,and those of control groups were injected with the saline at same dose.The behavior change in the epileptic and control group A was observed and electroencephalogram(EEG)was also undertaken.Cats of epileptic and control group B were performed ME-fMRI,and the percentage of the enhanced signal intensity was then calculated.Results After injection with PTZ(55 mg/kg)intramuscularly,epileptic seizure was all evoked,and then EEG recording showed spike-wave and polyspike-wave complexes.The neocortex of cats of epileptic group B was diffusely phanero-enhanced on ME-fMRI.The percent enhancement of signal intensity in cortex of frontal lobe,parietal lobe and occipital lobe was(34.6?5.7)% and that in cortex of temporal lobe with(22.9? 6.5)%,whereas those of control group B with(14.9?4.5)% and(11.6?3.2)% respectively.And there was significant difference between the above different localization of the brain in the two groups (t=-10.43,-5.46 respectively,P
