High mobility group protein B1 (HMGB1) is the most representative substance in the alarmins family, it is actively or passively release to extracellular by the activation of monocyte/macrophage and the dead cells, and then it stimulates the production of a variety of inflammatory mediators, and increases the organism's inflammatory response through relevant receptors signaling pathways. In recent years, its concentration can reflect the severity of inflammation and injury and was related to the prognosis, HMGB1 has won more and more attention in the development of sepsis. By reviewing the study of HMGB1 in sepsis pathogenesis, signal pathway and reversal measures, it was found that HMGB1 was considered as an important inflammatory mediators and warning signal involved in the pathogenesis of sepsis, and was become a new target in the treatment of sepsis. Further research on the role of HMGB1 in the pathogenesis of sepsis is needed in the future, and the development of new drugs combined with HMGB1 will be used in the study of HMGB1 in animal experiments.

Objective To investigate the protective effect of agmatine (AGM) against peritoneal inflammatory response and neutrophil (PMN) infiltration induced by zymosan (ZYM) in mice. Methods Thirty-six adult male C57BL/6 mice were randomly divided into sham group, model group, and AGM treatment group. Peritonitis model was reproduced by intra-peritoneal injection of 1 mg/mL ZYM (0.5 mL), while equivalent phosphate buffer saline (PBS) was given to sham group. 200 mg/kg AGM was injected into peritoneal cavity after ZYM challenge in AGM treatment group. Six mice in each group were sacrificed at 2 hours and 6 hours, respectively, after reproduction of the model. Blood sample and peritoneal lavage fluid (PLF) were collected. The levels of keratinocyte-derived chemokine (KC), macrophage inflammatory protein 2 (MIP-2), tumor necrosis factor-α (TNF-α), interleukins-6 (IL-6) in serum and PLF were determined by enzyme linked immunosorbent assay (ELISA). The number of leukocytes and PMN in PLF were determined by hemocytometer and flow cytometry, respectively. Results Compared with sham group, all serum and PLF levels of KC, MIP-2, TNF-α and IL-6 were greatly elevated at 2 hours after ZYM injection in model group, while AGM treatment could dramatically reduce the levels of the above-mentioned cytokines in serum and PLF as compared with those of the model group [serum KC (ng/L): 990.7±137.9 vs. 2 053.2±262.7, MIP-2 (ng/L): 642.2±124.4 vs. 1 369.7±146.5, TNF-α (ng/L): 608.6±38.1 vs. 1 044.7±101.0, IL-6 (ng/L): 1 058.2±129.1 vs. 1 443.3±190.1; PLF KC (ng/L): 7 462.3±839.6 vs. 12 723.5±1 515.7, MIP-2 (ng/L): 1 570.8±193.4 vs. 3 471.4±384.7, TNF-α (ng/L): 1 115.8±156.7 vs. 1 499.2±231.2, IL-6 (ng/L): 2 646.5±223.2 vs. 3 126.7±291.4; all P < 0.05]. The expressions of KC, MIP-2 and TNF-α at 6 hours were significantly lower than those at 2 hours in model group and AGM treatment group, but IL-6 levels were further increased. The levels of KC and MIP-2 in serum and PLF at 6 hours were decreased to the levels of sham group. At 6 hours after the reproduction of the model, the number of total inflammatory cells and PMN of PLF in the model group was significantly higher than those of the sham group. In contrast, AGM notably lowered the number of inflammatory cells and PMN in peritoneal fluid after ZYM attack [total inflammatory cells (×109/L): 14.7±1.1 vs. 2.0±0.4, 10.1±1.2 vs. 14.7±1.1; PMN (×109/L): 11.37±1.22 vs. 0.18±0.05, 7.69±0.57 vs. 11.37±1.22, all P < 0.05]. Conclusion AGM can effectively alleviate acute peritoneal inflammatory injury induced by ZYM, mainly through reducing the secretion of inflammatory mediators and chemokines, and inhibiting the infiltration of leukocytes and neutrophils.

Objective To evaluate thetherapeutic effect of sodium deoxyribonucleotide injection at Zusanli point for chemotherapy-induced leukopenia in patients with lung cancer.MethodsA total of 116 chemotherapy-induced leukopenia patients with lung cancer were randomly divided into a therapy group and a control group, 60 in the treatment group and 56 in the control group. The patients in the treatment group were treated with sodium deoxyribonucleotide injection atZusnlipoint, and those in the control group were treated with vein injection of sodium deoxyribonucleotide.Results The total effective rate in the treatment group was significant higher than that in the control group (91.7%vs.76.8%;χ2=4.890,P=0.032). The effective rates on days 3,5,7 and 10 in the treatment group were also significant higher than those in the control group (on day 3: 51.7%vs. 32.1%,χ2=4.530,P=0.036; on day 5: 76.7%vs. 53.6%,χ2=6.840,P=0.018; on day 7: 85.0%vs. 67.9%,χ2=4.770,P=0.026; on day 10: 78.3%vs. 53.6%,χ2=7.960,P=0.011).Conclusion Sodium deoxyribonucleotide injection atZusanlipoint has definite efficacy for chemotherapy-induced leukopenia in patients with lung cancer.

Objective To analyze the influence of diabetes mellitus (DM) on the outcomes of percutaneous transluminal angioplasty (PTA) with stenting of femoropopliteal artery,in patients with atherosclerotic occlusive disease (ASO).Method Clinical data of inpatients who successfully received PTA with stenting procedures of femoropopliteal artery in Xuanwu Hospital from January 2006 to December 2012 were analyzed retrospectively.Patients were stratified into DM and non-DM groups.Results were compared between the two groups including primary patency (PP),assisted patency (AP),limb salvage and survival using Kaplan-Meier life table and Cox regression analyses.Result Totally 291 patients underwent 332 procedures.There were 214 DM and 118 non-DM limbs.Mean follow-up was 34 months.The 5-year PP was 23.2％,AP was 35.3％,limb salvage was 89.2％,and survival was 69.6％.DM was associated with lower 5-year PP,limb salvage,and survival than non-DM.But there were no significant difference in AP between the two groups.Females were associated with decreased PP than males on Cox multivariate analysis.Hypertension and below tibial diseases were associated with lower limb salvage rate and age is the only predictor of survival rate.Conclusions DM is a risk factor for poor outcomes after PTA with stenting procedures.

Objective To investigate the serological characteristics and molecular basis of the B (A)phenotype in ABO blood group and provide the data for clinical transfusion of individuals with B(A) phenotype.Methods The ABO group antigens on red cells of the proband,family members and donors were identified by monoclonal antibodies and the ABO antibodies in sera were detected by the standard A,B,O cells.The compatibility testing for the proband and donors was detected by salted test,polybrene test and antiglobulin test.The coding region of exon 6 to exon 7 in ABO gene was amplified by polymerase chain reaction(PCR) and the PCR products were sequenced.The haplotypes of proband were analyzed by cloning and sequencing.Results It was showed that both A and B antigens were detected on red cells of the proband and her two family members,and there was anti-A_1 antibody in their sera.The serological phenotype of the samples are identified as the A_2B.DNA sequencing showed 261 G/del,297A/G,526C/G,657C/T,700C/G,703G/A,796C/A,803G/C,930G/A heterozygotes in exon 6 to exon 7.It can be deduced that genotype in the proband is B(A)_(02)/O_(01).The genotypes of her mother and grandmother-in-law were B(A)_(02)/B_(101) and B(A)_(02)/O_(01),respectively.After cloning and sequencing,two alleles B(A)_(02) and O_(01) in proband was showed.B(A)_(02) has snigle nucleotide change(700 C>G),which resets replacement of proline with alanine at position 234.Two donors with phenotype A_2B were identified as genotype B(A)_(02)/O_(01) and A_(208)/B_(101),respectively.The results of crossmatch testing is in accordane between the proband and two donors and there was no clinical adverse reaction after transfusion.Conclusions 700C>G in α-1,3galactosyltransferase allele(B allde)can result in B(A)phenotype in individuals with the phenotype of A_2B.The donors in the transfusion for the individuals with B(A) phenotype should include individuals with A_2B phenotype.
