Objective:To study the blocking effects of anti-sense peptide of C5a on the adhesion between pulmonary vascular endothelial cell(PVEC) and neutrophil resulting from C5a anaphylatoxin.Methods:It was determined by Flowcytometry that the change of adhesion molecule expression on PVEC and the activity of MPO in PMN was determined after adhesion.Results:In response to C5a after interactions with several concentrations of anti-sense peptide R4, the expression of P-Selectin on PVEC decreased significantly and reached the minimum at the concentration of 5 000 ng/ml, and the activity of MPO in PMN reduced by 40% at the concentration of 5 000 ng/ml of anti-sense peptide R4.Conclusion:The results suggested that anti-sense peptide of C5a has significant blocking effects on C5a anaphylatoxin.

Objective To investigate mutations in immediate early ( IE) gene ORF62 of three var-icella vaccine Oka strains ( vOka ) including two strains produced in China and their parental Oka strain (pOka), and then to further elucidate its possible roles in attenuation mechanism by comparing their ORF 62 promoter sequences and its activities , ORF62 coding regions and its transactivities .Methods ORF62 pro-moter-reporter plasmids and ORF62-expressing plasmids of pOka and three vOka strains ( vOka-BK from Changchun BCHT Biotechnology Co ., vOka-SH from Shanghai Institute of Biological Product Co .Ltd., and vOka-GSK from GlaxoSmithKline plc, as control) were constructed, respectively.ORF62 promoter regions and coding regions of the four strains were sequenced and then compared with each other .Differences of ac-tivities of the ORF62 promoter, and transactivities of the ORF62-encoded IE62 upon immediate early (ORF4), early (ORF28) and late (ORF67) gene promoters between pOka and vOka strains were assayed with transient transfection technique .Results Compared with pOka strain , three vOka strains had a con-sistent T deletion mutation at site 110 050 in ORF62 promoters, which did not result in any change of tran-scription factor binding motif .However , activities of ORF62 promoters from three vOka strains were signifi-cantly lower than those of pOka strain .Three consistent substitution mutations were observed in ORF 62 cod-ing regions of three vOka strains and three new enzyme restriction sites including SmaⅠ, NaeⅠand BssHⅡwere generated, respectively.Transactivities of IE62 from three vOka strains upon ORF4, ORF28 and ORF67 promoters were significantly higher than those of pOka both in CV-1 and MeWo cells , except that vOka-SH IE62 showed significantly lower transactivities upon ORF 4 promoter than those of pOka strain in CV-1 cells.Conclusion Consistent T deletion mutation at site 110 050 in ORF62 promoters of three vOka strains might be responsible for the reduced promoter activities and the changes of IE 62 transactivities .How-ever , it seemed that cell types have no significant effect on ORF 62 promoter activity or IE 62 transactivity be-tween pOka and vOka strains .

Objective To investigate the effect of propofol on human renal tubule epithelial cell (HK-2 cells) fibrosis induced by ATP depletion/recovery and the role of transforming growth factor β activated kinase 1 (TAK1) in it.Methods HK-2 cells were seeded in 96-well plates,and randomly divided into 4 groups (n =36 each) using a random number table:control group (group C),ATP depletion/recovery group (group D/R),propofol group (group P),and TAK1 over-expression group (group T).HK-2 cells were exposed to antimycin A for 1 h and then returned to normal culture medium to establish the model of ATP depletion/recovery-induced injury.At 1 h before ATP depletion,the cells were incubated for 1 h in the DMEM liquid culture medium containing propofol with the final concentration of 20 μmol/L in group P,and the cells were incubated for 1 h in the DMEM liquid culture medium containing propofol with the final concentration of 20 μmol/L and TAK1 with the titer of 2× 107 TU/ml in group T,and the other treatments were similar to those previously described in group D/R.At 12 h after ATP recovery,the cell viability was evaluated by methyl thiazolyl tetrazolium assay,and cell apoptosis was detected using TUNEL and scored.The expression of TAK1 was detected using Western blot at 12,24 and 48 h after ATP recovery.The expression of α-smooth muscle actin (αSMA),fibronectin (FN),and collagen protein 1 (COL1) was measured at 48 h after ATP recovery.Results Compared with group C,the cell viability was significantly decreased,the apoptosis score was increased,and the expression of TAK1,COL1,αSMA and FN was up-regulated after ATP recovery in D/R,P and T groups (P＜0.05).Compared with group D/R,the cell viability was significantly increased,the apoptosis score was decreased,and the expression of TAK1,COL1,αSMA and FN was down-regulated after ATP recovery in P and T groups (P＜0.05).Compared with group P,the cell viability was significantly decreased,the apoptosis score was increased,and the expression of TAK1,COL1,αSMA and FN was up-regulated after ATP recovery in group T (P＜ 0.05).Conclusion Propofol can reduce HK-2 cell fibrosis induced by ATP depletion/recovery,and the mechanism may be related to down-regulation of TAK1 expression.

Conclusion Ultrasound-guided anterior quadratus lumborum block combined with general anesthesia can reduce the consumption of opioids in the perioperative period and is helpful in improving outcomes when used for laparoscopic radical resection of rectal carcinoma.

BACKGROUND: The HELIOS stent is a sirolimus-eluting stent with a biodegradable polymer and titanium oxide film as the tie-layer. The study aimed to evaluate the safety and efficacy of HELIOS stent in a real-world setting. METHODS: The HELIOS registry is a prospective, multicenter, cohort study conducted at 38 centers across China between November 2018 and December 2019. A total of 3060 consecutive patients were enrolled after application of minimal inclusion and exclusion criteria. The primary endpoint was target lesion failure (TLF), defined as a composite of cardiac death, non-fatal target vessel myocardial infarction (MI), and clinically indicated target lesion revascularization (TLR) at 1-year follow-up. Kaplan-Meier methods were used to estimate the cumulative incidence of clinical events and construct survival curves. RESULTS: A total of 2998 (98.0%) patients completed the 1-year follow-up. The 1-year incidence of TLF was 3.10% (94/2998, 95% closed interval: 2.54-3.78%). The rates of cardiac death, non-fatal target vessel MI and clinically indicated TLR were 2.33% (70/2998), 0.20% (6/2998), and 0.70% (21/2998), respectively. The rate of stent thrombosis was 0.33% (10/2998). Age ≥60 years, diabetes mellitus, family history of coronary artery disease, acute myocardial infarction at admission, and device success were independent predictors of TLF at 1 year. CONCLUSION: The 1-year incidence rates of TLF and stent thrombosis were 3.10% and 0.33%, respectively, in patients treated with HELIOS stents. Our results provide clinical evidence for interventional cardiologists and policymakers to evaluate HELIOS stent. CLINICAL TRIAL REGISTRATION ClinicalTrials.gov, NCT03916432.
