Objective To investigate the feasibility of tissue-specific gene therapy for bladder cancer using human UroplakinⅡ(UPⅡ) promoter. Methods The recombinant adenoviruses,Ad-hUPⅡ-TNF carrying tumor necrosis factor (TNF-?) under control of the hUPⅡ,were generated.ELISA showed the production and secretion of TNF by bladder cancer cells infected with Ad-hUPⅡ-TNF.The level of TNF in urine was identified with ELISA. Results ELISA showed that production and secretion of TNF by bladder cancer cells infected with Ad-hUPⅡ-TNF was distinctly higher than by non-urothelium cells infected with Ad-hUPⅡ-TNF and MTT showed that proliferation of bladder cancer cells was obviously inhibited.Conditioned medium from bladder cancer cells apparently inhibited cells of L929 proliferation,compared with conditioned medium from non-bladder cells by the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay.Intravesical inoculation of Ad-hUPⅡ-TNF also caused decreased tumor growth in orthotopic human bladder cancer model.The sustained high level of TNF in urine could be identified with ELISA. Conclusions TNF driven by hUPⅡ promoter has effective active in the inhibition of bladder cancer growth both in vivo and in vitro.These will undoubtedly yield a new approach of therapy for bladder cancer.

Objective To determine the feasibility and safety of transprostatic utricle seminal vesiculoscopy in the treatment of hemospermia. Methods Totally 11 patients with hemospermia, mean age of (46.6 ± 3.5) years, ranging from 38 to 68 years, for 3 months admitted from September 2012 to August 2015 were enrolled, Their main manifestations were hemospermia. Painful ejaculation was observed in 7 patients, and perineal and testicular pain occured in 4 patients. They all underwent transprostatic utricle seminal vesiculoscopy, and then were followed up for 3 to 6 months. Results Ten patients were operated successfully, but 1 patient failed. The operation revealed that the causes of hemospermia were seminal vesiculitis in 8 cases, seminal vesiculitis accompanied with seminal calculi in 2 cases, and ejaculatory duct cyst in 1 case. Operation time was (29.2 ± 3.2) min ( ranging from 25 to 37 min) , and hospital stay was 2 d ( from 2 to 4 d). Hemospermia disappeared in 10 patients within 1 month of surgery, and hemospermia recurrence was observed in 1 patient within 6 months. The patient was treated with transprostatic utricle Holmium laser incision, then hemospermia was dispeared,Two cases of postoperative epididymitis were cured after one week of antibiotic treatment. Conclusions Seminal vesiculoscopy is a safe and effective to treat hemaospermia.

Objective To evaluate measurement of the submucosal thickness with endoscopic ultrasonography (EUS) for activity of Crohn disease (CD).Methods Ten patients with active stage of CD and 10 healthy controls (HC) underwent EUS.Simple endoscopic score for Crohn disease(SES-CD)and submucosal thickness at the most severe lesions were measured and recorded.Submucosal thickness of the same region in CD patients were measured at remissive stage.In order to analyze the relationship between submucosal thickness and the stage of CD, submucosal thickness were compared among patients at active stage of CD, remissive stage of CD and HC.And the cut-off value of submucosal thickness was calculated to diagnose the stage of CD.Results The mean submucosal thicknesses of active stage and remissive stage of CD were 6.48±1.95 mm and 2.47±1.08 mm,respectively (P<0.01).The correlation analysis showed that submucosal thickness had a positive correlation with Crohn disease activity index(CDAI)(r=0.708,P<0.01) and SES-CD(r=0.807,P<0.01).Receiver operating characteristic curve analysis was used for 10 cases of CD patients and the area under the curve was 0.985(P<0.01).The cut-off value of submucosal thickness to diagnose active stage of CD was 3.85 mm, and the sensitivity and specificity reached 100% and 90% respectively.The Youden index was 0.9.Conclusion Measurement of gastrointestinal submucosal thickness by EUS could contribute to evaluate the stage of CD and to guide clinical treatment.

Objective To investigate the effect of Bcl-2 gene expression on the proliferation and apoptosis of human pancreatic cancer SW1990 cells.Methods Bcl-2 short guide RNA (Bcl-2-sgRNA) was designed and synthesized,and it was combined with CRISPR-Cas 9.After confirmation by gene sequencing,it was transfected into human pancreatic cancer cell line SW1990,then the cells with stable Bcl-2 gene knock-out were selected,and wild type SW1990 cells were used as control.The cell growth curve was determined by CCK-8 method.The number of clone formation was measured.Flow cytometry was used to measure cell cycle and apoptosis.Results Human pancreatic cancer cell line SW1990 with Bcl-2 gene knock-out was successful constructed.Compared with wild type SW1990 cells,the growth of SW1990 cells with Bcl-2 gene knock-out was inhibited,the number of clone formation was significantly decreased [(160.7 ± 10.0) vs (285.3 ± 14.2)],the proportion of G1 cells was significandy increased [(84.51 ± 0.97) ％ vs (57.49 ± 1.08) ％],the proportion of S phase cells significantly decreased [(12.82 ± 0.99) ％ vs (27.56 ± 1.65) ％],and apoptosis rate was remarkably increased [(12.67 ± 0.59) ％ vs (0.37 ± 0.35) ％],and the difference between the two groups was statistically significant (P ＜ 0.01).Conclusions Knock-out of Bcl-2 gene can inhibit the growth of human pancreatic cancer cell line SW1990,decrease the ability of clone formation,block the cell in G1 phase and greatly increase cell apoptosis rate.

Objective To survey on knowledge of home blood pressure monitoring (HBPM) in community physicians of Zhejiang province.Methods One hundred and thirty eight community physicians from Xiacheng District of Hangzhou Municipality were assigned in intervention group (n =70) or control group (n =68).The knowledge of home blood pressure monitoring was surveyed by using the China HBPM questionnaire in both groups.Results Total 132 valid questionnaires were returned,including 70 from intervention group and 62 from control group.The results showed that 80.0％ (61/70) physicians in intervention group and 62.9％ in control group frequently suggested hypertensive patients to have HBPM in out-patient clinics (P ＜ 0.05).Physicians who correctly instructed patients to use upper arm electronic sphygmomanometer,to measure blood pressure in morning and night,to repeat 2-3 times each time,to record result 3 times,and to take ≥ 135/85 mmHg(1 mmHg =0.133 kPa) as criteria of hypertension in intervention and control groups were 67.1％ (47/70) versus 32.3％ (20/62),5.7％ (39/70) versus 29.0％ (18/62),92.9％ (65/70)versus 66.7％ (40/62),38.6％ (27/70)versus 6.4％ (4/62)and 57.1％ (40/70) versus 38.7％ (24/62),respectively,and the differences between two groups were all statistically significant (P ＜ 0.05).As for measuring frequency,92.9％ (65/70) physicians in intervention group and 67.7％ (42/62) in control group considered that blood pressure should be measured every day for poorly controlled patients ; 81.4％ (61/70) versus 14.5 ％ (9/62) considered that blood pressure should be measured every week for well-controlled patients; 87.1％ versus 35.5％ (22/62) considered that blood pressure should be measured every year at least for people with normal blood pressure; there were significantly differences between two groups (P ＜ 0.05).The community physicians generally considered that HBPM can be used to improve the awareness of hypertension for patients and to increase the blood pressure control rate in community.

At 2nd week,the typical linear deposition of IgG along the glomerular basement membrane (GBM) was observed by fluorescence microscopy. Mesangial hyperplasia and crescent formation in glomeruli were also observed by light microscopy. In treatment group,all the above lesions were alleviated. CONCLUSION: It demonstrated that "Shen Yan Yi Qi Solution" might alleviate the pathological change of glomeruli and improve renal function.

Objective To evaluate the safety and efficacy of endoscopic ultrasonography(EUS) guided ethanol ablation in patients with insulinoma. Methods The data of 10 patients with insulinoma trea-ted at the First Affiliated Hospital of Guangxi Medical University from December 2013 to January 2015 were prospectively analyzed. Results The patients were given EUS-guided ethanol ablation with dose of 0. 10 to 2. 00 ml(average 0. 70 ± 0. 62 ml)in pancreatic lesions for 15 times. No complications were observed dur-ing and after the procedure. The blood glucose improved after the procedure[4. 8(3. 9-5. 5)mmol/ L VS 2. 4 (1. 9-2. 5)mmol/ L,P < 0. 05]and the serum insulin level significantly decreased[83. 7(40. 1-143. 5) pmol/ L VS 177. 3(66. 5-200. 6)pmol/ L,P<0. 05]. The average hospital stay was(4. 3±1. 5)days. The patients were followed up for 6-12 months. EUS indicated that the echo of pancreatic lesions changed from high to low. CE-EUS revealed low enhancement and lack of blood supply. Conclusion EUS-guided ethanol ablation may become a promising minimally invasive treatment for insulinoma because of its safety,efficacy and low price.

Objective To analyze the CT findings of invasive mucinous adenocarcinoma of the lung.Methods The CT findings of 7 patients with invasive mucinous adenocarcinoma of the lung were retrospectively analyzed. Results Six cases manifested isolated pulmonary nodules or masses, among which circular/round shape was in 6 cases,clear tumor-lung parenchyma interface was in 6 cases,lobular sign was in 5 cases,specular sign was in 6 cases,calcifications was in 3 cases,angiogram sign of contrast enhancement was in 4 cases, and the CT value was close to the liquid density in 6 cases. One case showed consolidation of lung with multiple nodules or mass, and the lesions had angiographic signs calcification, unenhanced area with water density as well. The CT findings of angiography signs, calcification and consolidation of regional focal liquid opacity had significance for the diagnosis.One case was misdiagnosed as tuberculosis and 1 case as hamartomas. Factors which caused misdiagnosis were irregularly shaped calcifications and angiographic signs in lesion, and the enhanced CT value was less than 20 HU. Conclusions The invasive mucinous adenocarcinoma of the lung has characteristic CT findings. In addition to the malignant tumor features. When plain CT scan finds the watery density, calcifications and angiographic signs in the lesion, the invasive mucinous adenocarcinoma of the lung should be considered.The enhanced CT scan shows no enhancement or enhanced value less than 20 HU is also the characteristic of invasive mucinous adenocarcinoma of the lung. MRI check will help us to improve the diagnostic accuracy.
