Objective To assess and analyze the current status of clinical guidelines for hypertension in the world by using the Appraisal of Guidelines for Research and Evaluation (AGREE) instrument.Methods The clinical guidelines for hypertension were identified and approved by searching China hownet,WANFANG database,PUBMED database,MEDLINE,Embase and related institutions and authorization web site from 1995 to January 2012,and relevant Web sites of agencies and organizations that produce and/or endorse guidelines.Names of the guidelines,published years and organizations,methodology of development and reference number were descriptively analyzed.AGREE instrument was used to evaluate the qualities of latest edited clinical guidelines for hypertension in countries all over the world.Results Nine guidelines were enrolled.The results showed that the hypertension guidelines scored the highest average of 88.4％ for clarity of presentation and reliability field; for applicability fields,scored an average of 86.1％; the scope and goal field scored an average of 83.8％; participants field scored an average of 71.7％; editorial independence field scored an average of 64.1％ ; rigor of development field scored the lowest average of 62.9％.The overall assessment showed that NICE 2011,Canada 2012,ESC 2009,Australia 2010 editions were the positively recommended guidelines,JNC7,Japan 2009,China Taiwan 2010,China 2010,South Africa 2011 editions were the recommended guidelines (still need to supplement and improve).No recommend or uncertain guide was found.Conclusions The quality of the hypertension guidelines is higher in general,but some common deficiency in the rigor of development and editorial independence in Asian and African guidelines formulated by the states still exists.There still exist certain gaps in evidence-based medical requirement.And the contents and quality are needed for further regulating and enhancing.A set of scientific systemic hypertension clinical guidelines evaluation system should be established.

Objective To investigate the suitable mode of cognitive-behavioral therapy for lung transplant recipients during waiting for lung and evaluate the effect to improve patients' physical and mental state.Methods 50 cases were randomly divided into the experimental group and the control group,each group with 25 cases.The control group received conventional treatment.The experimental group received cognitive-behavioral therapy in addition to conventional treatment.SAS and vital signs were measured in the two groups on admission,2 weeks and 4 weeks after admission.Results The SAS score of the experimental group was lower than the control group 2 weeks and 4 weeks after admission and SAS score decreased as the intervention extended.The SBp of the experimental group was lower than the control group 4 weeks after admission.There was no significant difference of DBp between two groups.The heart rate of the experimental group was lower than the control group 4 weeks after admission.The heart rate of the experimental group was lower on 2 weeks and 4 weeks after admission than on admission.4weeks after admission,the respiratory rate of the experimental group was lower than the control group and on admission.Conclusions Cognitive-behavioral therapy can reduce the level of anxiety and keep vital signs stable with good feasibility and effectiveness.

Objective To investigate the dynamic expressions of CXCL11 and its role in the pathogenesis of acute necrotizing pancreatitis (ANP).Methods Forty-eight SD rats were randomly divided into control group and ANP group,with 24 rats in each group.ANP model was induced by retrograde injection of 4％ sodium taurocholate (1 ml/kg body weight) into the biliary and pancreatic duct.The rats were sacrificed at 1,3,6,12 hours.Serum level of amylase was determined,pathological changes in pancreatic tissue were routinely observed and scored.The expression of CXCL11 mRNA and proteon in pancreas was measured by fluorescence quantitative polymerase chain reaction and immunohistochemical method.The serum levels of CXCL11 were measured by enzyme-linked immunoadsorbent assay.Results The serum levels of amylase in ANP rats were significantly higher than those in control group [(6153 ± 355)U/L vs (185 ± 32)U/L at 6 h,P ＜0.05],pathological changes in pancreatre tisues were more significant in ANP rats,and the pathological score was significantly higher than that in control group [(9.00 ± 0.63) vs (0.33 ± 0.12) points at 6 h,P ＜ 0.05] ; the expressions of CXCL11 mRNA and protein in pancreatic tissue were significantly increased than those in control group (3.13 ± 0.43 vs 0.99 ± 0.24,2.76 ± 0.27 vs 0.33 ± 0.12 at 6 h,P ＜ 0.05).The serum level of CXCL11 was significantly higher than that in control group [(112.1 ± 14.2)ng/L vs (56.8 ±4.3) ng/L at 6 h,P ＜0.05)].Conclusions CXCL11 is an early inflammatory mediator in acute pancreatitis,and involved in the pathogenesis of ANP in rats.

OBJECTIVETo study the antagonism of Zn-metallothionein (Zn-MT) to oxidative stress of rats with severe scalding after delayed resuscitation.

METHODS27 Wistar rats were randomly divided into three groups: normal control; burn with delayed fluid resuscitation group; and Zn-MT protected group. The rats were scalded with 30% total body surface area (TBSA) third degree burn. Four hours after injury, they were resuscitated, but Zn-MT (1 x 10(-5) mol/L) was given in the third group rats. 24 hours after they were scalded, blood was taken, RBCs were separated and labeled with electron spin resonance (ESR) spin label 3-maleimido-proxy l to detect membrane protein conformation. The serum was collected and added into the reaction system of xanthine, xanthine oxidase and ESR spin trap 5, 5-dimethylpyroline-N-oxide to assay the levels of superoxide dismutase (SOD) by ESR.

RESULTSThe ratios of strong solidity and weak solidity of RBC membrane proteins in the three groups were 0.352 +/- 0.043, 0.409 +/- 0.027, and 0.386 +/- 0.062 respectively, and the revolved times of membrane proteins were 1.300 +/- 0.210, 1.576 +/- 0.190 and 1.381 +/- 0.210 seconds respectively. Compared to the first group, the membrane protein conformation in the second group was changed remarkably, and the speed of membrane protein movement decreased significantly. However, those changes were alleviated obviously by Zn-MT. The SOD levels in serum of the three groups rats were 73.2% +/- 1.4%, 48.8% +/- 3.8% and 66.8% +/- 3.2% respectively. Compared to the normal control group, the SOD levels in serum of the second group decreased obviously. However, an excess of oxygen free radicals produced after injury could be scavenged by Zn-MT.

CONCLUSIONRBC membrane proteins of rats with severe scalding after delayed resuscitation were injured by oxygen free radicals produced after injury, and Zn-MT could alleviate this injury.

The clinic of this disease is not rare, but few reports are noted in China; doctors and patients lack of knowledge. This paper reviews the literature on SRED, summarizes the shortcomings of existing research, and proposes future research directions, aiming to provide references for researchers to further explore this field.

Objective:To observe the expression levels of small ubiquitinated protein specific protease (SENP) 1 and small ubiquitin-related modifier protein (SUMO) 1 in patients with diffuse large B-cell lymphoma (DLBCL), and analyze the clinical value of evaluating prognosis.Methods:The clinical data of 66 patients with DLBCL (DLBCL group) in Inner Mongolia People′s Hospital from February 2017 to October 2020 were retrospectively analyzed, and 60 cases of healthy people in the same period were selected as the healthy control group. The expression levels of SENP1 and SUMO1 were detected by enzyme linked immunosorbent assay (ELISA). The correlation between the expression levels of SENP1, SUMO1 and clinical characteristics was analyzed. The independent risk factors affecting the prognosis were analyzed by Cox multivariate analysis.Results:The SENP1 in DLBCL group was significantly higher than that in healthy control group (50.39 ± 6.86 vs. 7.47 ± 1.32), the SUMO1 in DLBCL group was significantly lower than that in healthy control group (8.84 ± 2.13 vs. 31.49 ± 5.89), and there were statistical differences ( t = 47.640 and 29.210, P<0.01). There were statistical differences in SENP1 and SUMO1 among patients with different clinical stages ( P<0.01). The expression levels of SENP1 and SUMO1 were correlated with clinical stage and international prognostic index (IPI) ( P<0.05), and were not correlated with age, gender, disease site and clinical symptoms ( P>0.05). The 3-year survival rate in patients with high SENP1 expression (30 cases) was significantly lower than that in patients with low SENP1 expression (36 cases), the 3-year survival rate in patients with high SUMO1 expression (38 cases) was significantly higher than that in patients with low SUMO1 expression (28 cases), and there were statistical differences (26.67% vs. 75.00% and 73.68% vs. 39.29%, P<0.05). Cox multivariate regression analysis result showed that clinical stage, IPI, SENP1 and SUMO1 were independent risk factors affecting the prognosis in patients with DLBCL ( HR = 1.352, 1.487, 2.048 and 3.295; 95% CI 1.180 to 1.691, 1.187 to 1.602, 2.536 to 4.023 and 2.752 to 5.325; P<0.05 or <0.01). Conclusions:In patients with DLBCL, SENP1 is highly expressed and SUMO1 is lowly expressed. The expression levels of SENP1 and SUMO1 are closely related to clinical stage and IPI in patients with DLBCL, and they are independent risk factors of the prognosis.
