Aim To clarify the regulation role of ca-thepsin B ( Cat B ) in cell proliferation and apoptosis induced by SAHA in ER-positive breast cancer cell line MCF-7.Methods MTT was used to screen the optimal concentration and treatment time of SAHA . The expression levels of related proteins were deter-mined by ELISA , and the morphological changes were observed through time-lapse live cell imaging acquisi-tion.Cell viability and apoptosis assay in MCF-7 cells were assessed by Muse Cell Analyzer with SAHA and /or Cystatin C treatment .Results MTT assay showed that the anti-tumor efficacy of SAHA was significant . The optimal concentration and treatment time were 10μmol? L-1 and 24 h respectively . ELISA assay showed that SAHA could induce expression of Cat B in MCF-7 cells.Real-time live-cell imaging experiments demonstrated that the combination treatment of Cystatin C and SAHA significantly resumed the inhibitory effect caused by SAHA alone .Cytology test showed that SA-HA alone obviously depressed the cell viability and in-duced apoptosis . However , the effect was reversed with the combination of Cystatin C .Conclusion Cat B plays an important role in apoptosis induced by SAHA in ER +breast cancer cells MCF-7.

Results The levels of urinary RBP, mALB, ? 2 MG, NAG in hypertension patients were significantly higher than those in controls ( P

Objective To evaluate the clinical effects of endobronchial ultrasound - transbronchial needle aspiration (EBUS-TBNA) in the evaluation of staging of lung cancer.Methods Between July 2008 to March 2010,the first 128 patients selected by CT or PET/CT scanning with lung cancer in whom metastatic carcinoma in the hilar and/or mediastinal lymph nodes underwent EBUS-TBNA and were clinically followed up.There were 102 males and 26 femals with the age of 37 - 85 years,average 60.1 years.Review the performance in check and the result of biopsy.Results From 128 patients of mean age 60.1 years ( range 37 - 85 ),189 lymph nodes were punctured.The mean diameter of the nodes was 12.3 mm and the range was 6-16 mm.There were no procedural complications.Accuracy,sensitivity,and specificity for EBUS-TBNA were 98.53％,98.50％,and 100％,respectively.Conclusion EBUS-TBNA allows real-time visualization of mediastinal and hilar lymph nodes,allowing sampling safely and efficiently.It has great potential for diagnosis of staging of lung cancer.

Objective To investigate the relapse factors and its control strategy for peptic ulcer patients .Methods A total of 160 cases of peptic ulcer patients who visited our hospital from Jan 2011 to Aug 2013 was retrospectively analyzed .The recurred pa-tients were assigned as the experimental group , and the others as the control group .The relapse factors for peptic ulcer were observed . Results Among 160 peptic ulcers , there were 46 cases with recurrence with a relapse rate of 28.8%.Single factor logistic regression analysis showed that smoking, drinking, the spring and autumn season, h.pylori (Hp) infection, non-steroid anti-inflammatory drugs (NSAIDs), mental factor, and male were the risk factors for recurrence of peptic ulcer .Further multivariable logistic regression analy-sis showed that smoking, drinking, mental factors, history taking NSAIDs, and Hp infection were also the risk factors for recurrence of peptic ulcer .Conclusions Smoking and alcoholism history , meatal factors , history of taking NSAIDs , and Hp infection were the in-dependent risk factors of recurrence of peptic ulcer , intervention of these risk factor might reduce ulcer recurrence .

Objective To explore the clinical efficacy of NEOVEIL in postoperative pulmonary air leakage of pulmonary bullae resection by video-assisted thoracic surgery. Methods We retrospectively analyzed clinical data of 37 cases received NEOVEIL combined with ATB45 in video-assisted thoracic surgery (the NEOVEIL group), and clinical data of 40 cases by ATB45 alone(the control group) . We compared postoperative hospitalization time, keeping time of pleural cavity tubes, the pulmonary leakage time and the incidence of pulmonary infection in the two groups. Results There was no postoperative mechanical ventilation,hemothorax and death. In the NEOVEIL group, the postoperative hospitalization time was 5 to 9 days, the postoperative keeping time of pleural cavity tubes 2 to 4 days, the postoperative pulmonary leakage time 0 to 2 days with 4 patients un-leakage, and 1 patients with pulmonary infection; whereas the postoperative hospitalization time was 6 to 10 days,the postoperative keeping time of pleural cavity tubes 3 to 6 days,the postoperative pulmonary leakage time 2 to 5 days and 8 patients with pulmonary infection in the control group. There was statistical significance in the postoperative hospitalization time, keeping time of pleural cavity tubes, the pulmonary leakage time and the incidence of pulmonary inflammation in two groups(P ＜ 0. 05). The incidence of pulmonary inflammation of the NEOVEIL group (2. 7%) was significantly lower than that of the control group(20. 0%)(x2 = 4. 02, P ＜ 0. 05). Conclusion The operative effectiveness of the NEOVEIL group is better than that of the control group. The NEOVEIL can prevent the postoperative pulmonary leakage.

OBJECTIVE:To investigate clinical efficacy and safety of recombinant human tissue type plasminogen activator (rt-PA) intravenous thrombolytic in the treatment of elderly patients (over 75 years old) with acute cerebral infarction (ACI). METHODS:78 elderly ACI patients,on the basis of routine treatment,were divided into thrombolysis group (40 cases) and non-thrombolysis group (38 cases) according to the will of patients or family members. Non-thrombolysis group received aspirin 200 mg,qd;thrombolysis group was given rt-PA 0.9 mg/kg(maximum dose of 90 mg)by intravenous push of 10% dose within 1 min,and intravenous dripping of residue dose within 60 min;receiving aspirin 200 mg,qd,24 h after thrombolytic therapy with-out contraindications. Both groups were treated for 14 days. The effective rate,NIHSS score before treatment and 24 h,7 d and 14 d after treatment,prognosis after 90 d were compared between 2 groups,and the occurrence of ADR was observed in 2 groups. RE-SULTS:The total effective rate was 67.50% in thrombolysis group and 52.63% in non-thrombolysis group,with statistical signifi-cance(P<0.05);there was significant difference in NIHSS score between 2 groups 24 h,7 d,14 d after treatment(P<0.05);90 d prognosis of thrombolysis group was superior to that of non-thrombolysis group,there was statistically significance (P<0.05);there was no statistical significance in the incidence of ADR between 2 groups (P>0.05). CONCLUSIONS:4.5 h time window rt-PA intravenous thrombolytic therapy is safe and effective for elderly patients with ACI,and can reduce disability and fatality,im-prove prognosis.
