ObjectiveTo investigate the diagnostic value of transbronchoscopic lung biopsy (TBLB) without X-ray fluoroscopy in patients with peripheral pulmonary lesions.Methods Fifty patients with peripheral and diffuse pulmonary lesions and without cavity lesions from January to December 2011 were selected and examined by conventional hronchoscopy.According to the anatomical orientation of CT image and bronchial tree path,TBLB was performed by electronic bronchoscope.ResultsThere were 63 cases of TBLB in 50 patients and 30 patients got confirmed diagnosis (60.0％),including 24 cases in 35patients with peripheral pulmonary lesions (68.6％),and 6 cases in 15 patients with diffuse pulmonary lesions (40.0％).There was no severe complication during and after electronic bronchoscopy.ConclusionsTBLB without X-ray fluoroscopy is a convenient,safe and repeatable operational method with fewer complications.It has higher clinic diagnostic value in pulmonary diseases.

Objecive To evaluate and compare the efficacy of injecting tissue glue and lauromacrogol in modified sandwich method combined with synchronous ligation for patients with esophageal and gastric variceal.Methods 42 cases of patients with esophageal and gastric variceal were randomly divided into synchronous treatment group (22 cases) and sequential treatment group (20 cases). Both group received modiifed sandwich method for gastric varices (lauromacrogol-tissue adhesive-lauromacrogol). Synchronous treatment group meanwhile received synchronization ligation for esophageal varices, but sequential treatment group received sequential ligation after one week. The hemostasis rate, effective rate of varices, rebleeding and complications rate were analyzed.Results There were no signiifcant difference in hemostasis rate, effective rate and rebleeding rate between two groups. The incidence of complications, such as chest and abdominal pain, fever, transient bacteremia were equal between these two groups. No patients had ectopic embolism. The number of ligation device in synchronous treatment group was more than sequential treatment group (8.19 ± 2.01 vs 7.81 ± 1.78,P > 0.05), and the rate of esophageal varices disappearance was inferior to sequential treatment group (59.09% vs 70.00%), however, there were no statistical difference (P > 0.05).Conclusion Endoscopic injection of tissue glue and lauromacrogol synchronization ligation is safe and effective for esophageal and gastric variceal with low complication rates. This method could reduce gastroscopy times and medical expenses, and is worthy of further investigating.

To study the effect of miR-490 on Coxsackievirus B3 (CVB3) replication, HeLa cells were trans- fected with miR-490 in vitro, and infected with a Renilla luciferase (RLuc)-expressing CVB3 variant (RLuc-CVB3). The activities of RLuc in these cells were measured at 8h intervals from 0 to 40 h post-infection (p.i.), and the effects of miR-490 on RLuc-CVB3 replication were observed. In a further study, HeLa cells were transfected with either miR-490 or antisense miR-490 (AMO-miR-490), and were then infected with an enhanced green fluorescence protein (EGFP)-expressing CVB3 variant (EGFP-CVB3). The replication of EGFP-CVB3 was then determined by detecting the expression of EGFP. We observed that miR-490 could significantly inhibit the expression of RLuc in infected cells at 32 h p. i. Furthermore, in HeLa cells infected with EGFP-CVB3 at 32 h p.i., EGFP expression was also significantly inhibited by the presence of mniR-490. The inhibitory effect of miR-490 on EGFP expression in EGFP-CVB3-infected cells could be reversed by tranfection with AMQ-miR-490. These results indicated that miR-490 significantly inhibits the replication and expression of QVB3.

To investigate the biological role of snake venom cystatin(sv-cystatin) in tumor progression, the cDNA of sv-cystatin amplified by PCR from pUC18-cystatin plasmid was cloned into methanol-inducible expression vector pPICZ?A. The linearized recombinant plasmid pPICZ?A-cystatin was transfered into Pichia pastoris, strain GS115 by electrophoration. Transfermants with phenotype Mut+ selected were identified by PCR analysis and induced in 1.0% methanol. The reombinant sv-cystatin protein was examined by SDS-PAGE, Western blot analysis. The molecular mass of expression product was about 14 kDa and approximately 16 mg/L of recombinant sv-cystatin was produced from one of GS115-cystatin transformants. The chromatography purified protein could reduce the activity of papain. The ability of B16F1 cells treated with recombinant sv-cystatin to invade the reconstituted basement membrane decreased significantly (P

Objective To investigate the application value of clinical typing in the treatment of BuddChiari syndrome (BCS).Methods The retrospective corss-sectional study was adopted.The clinical data of 95 patients with BCS who were admitted to the First Affiliated Hospital of Zhengzhou University from January 2012 to September 2015 were collected.Based on patients' compensation and clinical symptoms,3 clinical typing and 8 subtypes of BCS were proposed,and each subtype was treated with corresponding strategies.Observation indices included (1) the clinical typing of BCS,(2) selection of treatment,(3) treatment effect,(4) follow-up situations.Follow-up using telephone interview and outpatient examination was performed once within 3 months after the first treatment and then once every 6 months up to December 2015 or death,loss to follow-up and experienced decompensation.During follow-up,color Doppler ultrasound and blood bio-chemistry test were performed regularly,and CT angiography was also conducted when necessary.Count data were presented as the case or percentage.The survival rate was calculated using Kaplan-Meier method and the survival curve was drawn.Results (1) BCS clinical typing of 95 patients:4 were detected in type Ⅰ (3 in type Ⅰ a and 1 in type Ⅰ b),7 in typeⅡ (4 in type Ⅱa and 3 in type Ⅱb),and 84 in type Ⅲ(43 in type Ⅲa,4 in type Ⅲb,32 in type Ⅲc,and 5 in type Ⅲd).(2) Selection of treatment in 95 patients:① among the 3 patients with type Ⅰ a,2 of them received inferior vena cava balloon angioplasty while 1 patient had to give up the operation due to failure in opening the occlusion.This patient underwent close observation and follow-up afterwards.② The patient with type Ⅰ b underwent cavity-antrum artificial blood vessel bypass operation due to failure in opening the occlusion.③Among the 4 patients with type Ⅱ a,one of them underwent hepatic vein balloon angioplasty.The other 3 patients underwent close observation and follow-up because of failure in intervention therapy,such as segmental occlusion of hepatic vein or difficulty in finding the hepatic vein.④ Among the 3 patients with type Ⅱ b,due to the history of upper gastrointestinal bleeding,2 patients received modified spleen-lung fixation and intestine-cavity blood vessels bypass,respectively,and 1 patient received intestine-cavity artificial blood vessels bypass due to severe peritoneal effusion.⑤ Among the 43 patients with type Ⅲ a,35 patients underwent inferior vena cava balloon angioplasty due to failure in hepatic vein intervention therapy (6 of them received firstly thrombolysis treatment due to combined thrombosis.Four patients received inferior vena cava and hepatic vein balloon angioplasties.Another 4 patients received close observation and follow-up due to failure in both inferior vena cava and hepatic vein intervention therapy.⑥Among the 4 patients with type Ⅲ b,2 underwent inferior vena cava balloon angioplasty and intestine-cavity artificial blood vessel bypass.The other 2 patients only received modified spleen-lung fixation because of failure in inferior vena cava intervention therapy.⑦ Among the 32 patients with type Ⅲ c,3 underwent inferior vena cava and hepatic vein balloon angioplasties,and 27 patients underwent only inferior vena cava balloon angioplasty due to failure in hepatic vein intervention therapy (7 of them received balloon angioplasty following thrombolysis treatment due to combined thrombosis).On account of failure in both inferior vena cava and hepatic vein intervention therapy,2 patients underwent resection of lesion membranes and cavity-antrum artificial blood vessel bypass,respectively.⑧ Among the 5 patients with type Ⅲ d,1 underwent inferior vena cava balloon angioplasty and intestine-cavity artificial blood vessel bypass,and 4 underwent only modified spleen-lung fixation due to failure ininferior vena cava intervention therapy.(3) Treatment efficacy:of 95 patients,8 received followup observation,and 87 patients recovered to varied extent after interventional therapies and operations,with symptomatic relief of leg edema,ulcer,peritoneal effusion and esophageal varicosity.Eighty-seven patients went through the perioperative period safely,and no death occurred.The incidence of postoperative complications was 10.3％ (9/87).The complications mainly include venous thrombosis in lower limbs during catheter-directed thrombolysis therapy,pleural effusion,pneumatosis,and peritoneal effusion after surgery,all of which were cured after symptomatic treatment.(4) Follow-up results:87 were followed up for 3-42 months with an average time of 19 months.During the follow-up,5 patients (1 in type Ⅰ a and 4 in type Ⅲa) received recanalization surgery because of the reocclusion after the inferior vena cava balloon angioplasty,and no decompensation occurred.However,decompensation was found in 11 patients (disease progression in 4 patients and symptom relapse in 7 patients).The survival rates of patients without decompensation at 0.5,1.0,2.0 and 3.0 years after the first treatment were 96.5％,95.0％,83.4％ and 80.5％,respectively.Conclusion According to patients' compensation and clinical symptoms,clinical typing of BCS and treatment strategiesis are determined,and it will provide a satisfactory clinical efficacy.
