Objective To analyze the clinical features and prognostic factors of lymphoma.Methods The clinical data,pathologic data and survival state of 253 patients with lymphoma in Qinghai were retrospectively studied.The survival differences of patients with different clinical characteristics and laboratory tests were analyzed using Kaplan-Meier method.The prognostic factors of lymphoma were analyzed by Cox proportional hazards regression model.Results Among all of 253 cases of lymphoma,males were in the majority (male∶female =1.56∶1).The median age of patients was 48 years old.There were two peaks of about 40 years old and 60 years old in age of onset.The nodal lymphoma (56.13 ％) was more commonly than the extranodal lymphoma (43.87 ％).The more common extranodal lymphomas were found in the nasopharynx and gastrointestinal tract.Among all cases,40 cases (15.81％) were confirmed to be Hodgkin lymphoma (HL),of which,the commonest subtype was nodular sclerosis (72.5 ％).While 213 of 253 cases (84.19 ％) belonged to non-Hodgkin lymphoma (NHL),of which,B-cell lymphoma was 148 cases (69.48 ％).Overall,three subtypes including diffuse large B-cell lymphoma (39.91％),follicular lymphoma (12.21％) and peripheral T-cell lymphoma (9.39 ％) were the commonest subtypes among all cases.Univariate analysis showed that the clinical stage,B symptoms,Hb concentration,serum LDH level,international prognostic score (IPI) and treatment programs were related to the prognosis of NHL (P ＜ 0.05).However,the Cox regression multivariate analysis showed that only the clinical stage,IPI and treatment programs,not B symptoms,Hb concentration and serum LDH level,were closely related to the prognosis of NHL (P ＜ 0.05).Conclusions In Qinghai area,there are two peaks of about 40 and 60 years old in the age of onset of lymphoma.The nodal lymphoma is more than extranodal lymphoma.B-cell lymphoma is more common.IPI could be as an independent prognostic factor and might be used to estimate the prognosis of NHL.

Objective: To search for a satisfactory method for establishing Stanford B type aortic dissection model in canine. Methods: Totally 12 adult dogs were used in the present study. The proximal descending aorta was clamped partially and laterally after a left thoracotomy; half circumference of the aorta, including the media and adventitia,was cut open transversely, with the intima kept intact. The aortic wall was then separated inferiorly, laterally and superiorly at a special dissecting space with a unique dissecting device. Then the intima at the same site was also cut open transversely and the two ends of the distal intimal flap were sutured to the adjacent aorta to allow blood entry. The distal adventitia and media were sutured to the proximal aorta to close the incision. Follow-up was carried out with pigtail catheter guided digital subtraction angiography (DSA) using omnipaque (16-18 ml/s) via either of the common iliac arteries and color Doppler ultrasound. Results: Formation and distal extension of aortic dissections were observed immediately after the procedure and were further confirmed by intra-operative color Doppler ultrasound, DSA, and post-operative biopsy at different time points. Conclusion: The present two-end intimal flap suturing method can be used for establishing Stanford B type aortic dissection model in canine; the model is similar to human Stanford B type aortic dissection.

Objective To compare the efficiencies of imatinib and dasatinib in patients with chronic myeloid leukemia-chronic phase (CML-CP).Methods The databases were retrieved,including Cochrane Library,OVID,Embase,PubMed,China National Knowledge Infrastructure (CNKI),WanFang database and VIP database,besides,references of articles were further to search.The quality of randomized controlled trials (RCTs) was assessed by the Cochrane collaboration' s risk tool.Meta-analysis was performed by RevMan 5.1 software.Results A total of 5 articles involved 2 031 patients with CML-CP were included.Meta-analysis showed that the rate of complete cytogenetic response (CCyR) at the 12th month in dasatinib group was higher than that in imatinib group [83.6 ％ (478/572) vs 70.6 ％ (406/575),OR =2.11,95 ％ CI 1.59-2.80,P＜ 0.05],and the rate of major molecular response (MMR) at the 12th month in dasatinib group was higher than that in imatinib group [49.3 ％ (296/600) vs 30.6 ％ (185/605),OR =2.22,95 ％ CI 1.75-2.82,P ＜ 0.05].Conclusion Dasatinib can improve CCyR and MMR rate at the 12th month in CML-CP patients.

ObjectiveTo observe the influence of medical exercise on rehabilitation of patients suffering from chronic obstructive pulmonary disease (COPD).Methods26 COPD patients who were organized in the form of training class practised medical exercise for three months. Respiratory function, exercise capacity and psychological health level were assessed respectively before and after exercise.ResultsValues of forced vital capacity(FVC), forced expiratory volume in one second (FEV1), FVC% , FEV1/ FVC and 6-minute walking distance (6MD) were significantly higher after medical exercise than before(P<0.01). Anxiety and depression scores also notably dropped after medical exercise than before(P<0.01).Conclusions Medical exercise can remarkably improve respiratory and moving capacity and decrease anxiety and depression of patients suffering from chronic obstructive pulmonary disease.

Objective To evaluate the effect of double tractors swing microendoscopic discectomy technique in multi-segmental lumbar disc herniation. Methods From December 2006 to November 2009,153 patients with multi-segmental lumbar disc herniation were treated with double tractors swing microendoscopic discectomy. They included 85 cases of multi-segmental disc herniation, 53 cases of degenerative canal stenosis and 15 cases of lumbar instability. Among them, 2, 3, 4 and 5 fenestrations were performed in 105,33, 13 and 2 cases respectively and interbody fusion was done with "quanhe" inflation cage and screws in 15 cases. The results were evaluated with Macnab scale. Results All the 153 patients were followed from 3to 36 months, with an average of 16 months. The mean operative time was 45, 61, 83 and 110 min for 2,3,4 and 5 fenestrations respectively, with a mean blood loss of 150 ml. And it took extra 92 min to finish interbody fusion. Complications included dural sac tears in 1 case,canda equina slight lesion in 1, superficial incision infection in 1, the formation of deep venous thrombosis in 1, and revision for"quanhe"inflation cage in 1. The mean hospital stay was 10 days. Excellent results were obtained in 117 cases, good in 32 and fair in 4. One hundred and thirty-two patients returned to their work or normal activities in 3 weeks. One hundred and forty-nine cases were satisfied with the therapeutic effect. Conclusion This technique not only can reach adjacent intervertebral space easily but also disperse pressure on the nerve root effectively. This technique can provide thorough decompression and good results.

Objective To estimate the efficacy and safety of Voriconazole as antifungal prophylaxis of invasive fungal infection ( IFI) for malignant hematology patients. Methods The randomized controlled trials of Voriconazole treatment in invasive fungal infection for malignant hematology patients (ended in September 2014) were searched from Cochrane library, Medline, Embase, Pubmed, CBM, CNKI, Blood database. The meta analysis were performed by RevMan5.0. Results Ten literatures reported in 1 773 cases, in which there was significantly difference in effective rate between Voriconazole and other antifungal agents such as Amphotericin-B, Itraconazole, Micafungin and Fluconazole(P < 0.000 01); Four literatures indicated that there was significantly difference in adverse event rate between Voriconazole and amphotericin-B (P < 0.00 001); no significantly difference in adverse event rate between Voriconazole and amphotericin-B(P = 0.57); no significantly difference in adverse event rate between Voriconazole and Micafungin (P = 0.69); no significantly difference in adverse event rate between Voriconazole and Fluconazole (P = 0.70); Subgroup analysis indicated that adverse event rate between Voriconazole and Itraconazole is P=0.001, P = 0.17 respectively. Conclusion Voriconazole showed relative high efficient and low toxicity characteristics in treatment of malignant hematology accompanied by invasive fungal infection. But with its widely clinical application, the clinical value of Voriconazole needs to be further tested.
