Objective To investigate the clinical efficacy of psychological intervention and gefitinib in the treatment of elderly patients with non-small cell lung cancer with limited pulmonary resection. Methods The control group were all treated with limited pulmonary resection. Preoperative chemotherapy was given to gefitinib. The study group was given psychological intervention during the preoperative chemotherapy on the basis of the control group. Results The resection rate in the study group was 93.55％, while in the control group was 74.19％, the difference in the two groups was statistically significant(P<0.05). The transfer rate was 3.23％ and the recurrence rate was 3.23％ in the control group, which was significantly lower than those in the control group the transfer rate of 19.35％, the recurrence rate of 16.13％. 1 years survival rate in the study group 80.65％ was significantly higher than that in the control group 64.52％, the difference was statistically significant(P<0.05). Conclusion On the basis of routine preoperative application of gefitinib combined with local excision treatment, the elderly patients with non-small cell lung cancer with psychological intervention measures can make them achieve more ideal effect and prognosis.

12 ml/s was used as Group A and Qmax ≤12 ml/s as Group B. Results One week after removal of urinary catheter, dysury appeared in five cases with Qmax for (9.45?2.62) ml/s, of which two cases were with posterior urethral stricture, two with benign prostatic hyperplasia and one with weak detrusor contraction. Three months after removal of urinary catheter, six cases led to secondary dysuresia due to posterior urethral stricture and had Qmax for (6.28?3.26) ml/s, with significant difference compared with urodynamic parameters of normal group (P

Abstract Objective To compare the quality of life in long-term hemodialysis patients using tunnel cuffed catheter with arterio-venous fistula. Methods Thirty patients using tunnel cuffed catheter (catheter group) and another 30 patients using arterio-venous fistula (fistula group) were observed. The rate of infection,thrombus and blood flow were recorded. The lab examinations such as blood urea nitrogen,creatinine,serum electrolyte,hemoglobin, C reactive protein, parathyrine, β2 microglobulin were measured,subjective global assessment (SGA) was made, KT/V and urea reduction ratio (URR) were calculated.Quality of life was surveyed with KDQOL-SFTM questionnaire and to conduct comparative analysis. Results KT/V was 1.49 ± 0.25 in catheter group, and 1.45 ± 0.28 in fistula group, there was no significant difference between the two groups. The lab examinations and SGA were similar in two groups. There were no significant difference of quality of life between the two groups except for pain (the score in catheter group was significantly higher than that in fistula group). The rate of infection was significantly higher in catheter group than that in fistula group. The rate of thrombus was similar in two groups. Conclusions As alternative of fistula in patients whose fistula could not be established, the tunnel cuffed catheter could give adequate dialysis and satisfactory quality of life,and is predominating in pain-reducing. The rates of infection and thrombus are decreased, but maintain the important problems to be solved.

Objective To evaluate the clinical features,therapies and prognosis in patients with mucosa-assoeiated lymphoid tissue (MALT) lymphoma in ocular adnexal marginal zone (OAML).Methods A retrospective analysis was made upon clinical data from 21 patients with OAML admitted into Beijing Tongren Hospital from June,2008 to December,2011.Results There were 12 (57.1 ％) men and 9(42.9％) women,with a median age of 57 (23-79) years old.Majority of patients had localized pathological changes.Among them,16 patients (76.2％) were in stage Ⅰ E,and 5 (23.8％) in stage Ⅳ E.Surgical resection as the sole treatment was performed in 13 patients (61.9％),and positron emission tomography CT(PET-CT) imaging demonstrated normal fluorine 18-fluorodeoxyglucose (FDG) uptake after surgical resection,who were managed with no further therapy.All the 13 patients were followed up for median 14 (5-38) months,and all in complete remission.Combination chemotherapy was given to 8(38.1％) patients.Three patients in stage Ⅰ E treated with COP (cyclophosphamide,vineristine and prednisone) or CHOP (cyclophosphamide,adriamycin,vincristine and prednisone) were all in partial remission.Five patients in stage ⅣE were treated with COP/CHOP in combination with rituximab,and all in complete remission.The 3-year overall survival rate and disease-free survival rate in the total patients were 100.0％ and 74.9％ respectively.Conclusions The patients with OAML generally have localized disease,show indolent clinical course,and present low lymphoma-related mortality.Surgical resection is a very important treatment in the patients with local disease.Systemic chemotherapy should be considered in patients at advanced stages.Rituximab in combination with chemotherapy can improve the remission rate.

Objective To investigate the expression and activity of transforming growth factor-β1 (TGF-β1)and endothelial nitric oxide synthase(eNOS) in the cavernous vascular structural remodeling of diabetic rats.Methods 52 adult male SD rats were randomly assigned to experimental group(DM) and control group(NDM).In DM group,diabetes was induced in rats 4 days after intraperitoneal injection with streptozotocin.HbA1c was measured on 2,4,8,and 16 weeks after injection.Penile tissues were harvested.The protein expression of TGFβ1 and eNOS in situ was evaluated by the Envision immunohistochemistry.Results Compared to NDM group,the expression of the HbA1c increased significantly in DM group on the 16th week(P ＜0.01),both the penile erection rate and penile erectile times decreased significantly in DM group on the 16th week (P ＜ 0.01),and the value of eNOS decreased on the 16th week(P ＜0.01).The expression of TGF-β1 went up in DM group compared to NDM group on the 8th week (P ＜ 0.01) and sustained to the 16th week (P ＞ 0.05).In DM group,we found that TGF-β1 protein in cavernous body of penis was positively related with age in weeks(r =0.947,P ＜0.01) ; and eNOS in cavernous body of penis was negatively related with age in weeks (r =-0.945,P ＜ 0.01).Meanwhile,the expression of TGF-β was negatively related with the eNOS(r =-0.891,P ＜0.01).Conclusion Our results indicate that TGF-β1 plays an important role in the pathogenesis of diabetic erectile dysfunction(ED) and TGF-β1 inhibition may be a promising strategy to prevent development of diabetic ED.

Objective To explore the diagnosis,treatment and prognosis of primary gastric malignant (lymphoma)(PGML).Methods The diagnosis and treatment data of 21 cases of PGML admitted in our(hospital) during 8 years was retrospectively analyzed.The diagnostic methods included barium meal(examination),gastroscopy,B type ultrasonography,and CT scan.All patients underwent operative treatment and most of the patients received adjuvant chemotherapy.Results Upper abdominal pain,digestive tract bleeding,emaciation and abdominal mass were common clinical manifestations of PGML.The resectabilty rate of PGML was 90.5% while the 5-year survival rate was 57.1%.Conclusions The key to a satisfactory prognosis was early diagnosis,radical curative operation and combined treatment.

Objective:To study the pathological mechanism of the inducible co-stimulator molecular and ligand ( ICOS/ICOSL) in Graves disease animal.Methods:45 out-bred BALB/c mice were randomly divided into three groups with 15 rats in each group;using gene gun to deliver different plasmid injection.Group A was delivered with pCDNA3.0-mICOSL and pCDNA3.0-hTSHR, Group B with pCDNA3.0-hTSHR and null pCDNA3.0 with Group C for immunization as the control group.The concentration of serum free thyroxine immunization was deter mined with immunoassay and serum thyrotropin receptor antibody ( TRAb ) with ELISA, supernatant of IFN-γconcentration in mouse spleen cells was measured with radioimmunoassay,and hTSHR transected CHO cells were incubated to detect the concentration of cAMP to deter mine autoantibody TRAb activity.Results: After plasmid injection serum FT4 level in Group A (0.49±0.25) pg/ml ( q=6.571,P=0.023) was higher than that in Group C,the standard rate was higher than Group B and C (χ2=14.47,P=0.005).IFN-γconcentration of mice spleen cultured supernatant in Group A (1.88±0.41) pmol/L was significantly higher than the other two groups.The activity of autoantibody TRAb in Group A 188.3 (179.7-260.2) %was higher than that in the other two groups ( P=0.027 ) .Conclusion: Exogenous delivery of pCDNA3.0-mICOSL plasmid in GD mice could stimulate the spleen lymphocytes to secrete more IFN-γ,increase the activity of TRAb autoantibodies and might lead to upregulation of immune response in Graves animal model in vivo.

Biomacromolecule drugs have been increasingly used in clinical practice due to their distinct advantages, including precise targeting, small dose, high safety and activity. However, owing to their high molecular weight, strong hydrophilicity, and poor stability in the gastrointestinal tract, the oral bioavailability of the biomacromolecule drugs remains extremely poor. As a novel and innovative technology for active drug delivery, gastrointestinal microneedles hold immense potential in the oral delivery of biomacromolecule drugs because of their low-invasive nature and high permeation enhancement effects. This review primarily summarizes the actuating force, design strategies, fabrication techniques, and applications of gastrointestinal microneedles for the oral delivery of biomacromolecule drugs. Additionally, the challenges and further perspectives in the development this technology are presented, aiming to promote the subsequent research and clinical translation of gastrointestinal microneedles, and to provide a new efficient and safe strategy for oral delivery of biomacromolecule drugs.
