Objective To evaluate the change of extended spectrum β-lactamase (ESBLs) Producing Klebsiella Pneumoniae (ESBLs-KPN) and Escherichia coli (ESBLs-ECO) causing nosocomial infection after antimicrobial intervention. Methods We regularly monitored the data on the yearly consumption [defined as daily dose (DDD) per 1 000 patient-days] of frequently used antibiotics from Dec. 2004 to Dec. 2007. From Jan. 2005 to Dec. 2007, we monitored the resistance of frequently used antibiotics and the timely integrative antimicrobial intervention was based on the outcome of antimicrobial resistance. We also monitored the isolation rate of ESBLs-KPN and ESBLs-ECO causing nosocomial infection. The departments studied were the experimental group and other comparable medical departments were the control group(ICU was excluded).Results The isolation rate of ESBLs-KPN ((43.90%)) and ESBLs-ECO (45.83%) in the experimental group was higher than that in the control group (28.04% and 24.90%, respectively) before the intervetion (P＜0.05). The isolation rate of ESBLs-KPN decreased (from 26.47% to 17.65%) in the experimental group and that in the control group increased ( ESBLs-KPN: from 34.18% to (52.94%;) ESBLs-ECO: from 47.13% to 63.78%) from 2005 to 2007 (P＜0.05). The isolation rate of ESBLs-KPN and ESBLs-ECO in the experimental group was lower than that in the control group after the antimicrobial intervention (P＜0.05). Usage of ceftazidime and cefoperazone/sulbactam and imipenem was reduced and the consumption of cefepime was increased in the experimental group ((P＜0.05)). Consumption of ceftazidime and cefoperazone/sulbactam and cefepime was increased. Conclusion The prevalence of ESBLs-KPN and ESBLs-ECO may be decreased after the integrative antimicrobial intervention.

Objective To study the changes of plasma growth hormone releasing peptide(Ghrelin)level and its influencing factors in patients with hyperthyroidism.Methods 55 patients with hyperthyroidism (observation group)and 55 healthy persons (control group)were selected.ELISA was used to detect plasma indicators before and after treatment.The level of body fat percentage,Ghrelin,S -TSH and FT3 ,FT4 of the two groups before and after treatment were compared,and the relationship between Ghrelin and FT3 ,FT4 ,percentage of body fat,plasma S -TSH was analyzed.Results Compared with the control group,the percentage of body fat,Ghrelin and S -TSH level in the observation group were lower,and FT3 ,FT4 levels were higher,there were significant differences between the two groups(t1 =5.021,t2 =9.628,t3 =23.054,t4 =29.325,t5 =28.967,P <0.05).Compared with before treatment,the body fat percentage,Ghrelin and S -TSH level of the observation group were higher after treatment,and FT3 ,FT4 levels were lower after treatment,the differences were statistically significant(t6 =5.282,t7 =8.651,t8 =21.835,t9 =27.126,t10 =26.855,P <0.05).The correlation analysis showed that FT3 and FT4 were negatively correlated with plasma Ghrelin level(r =-0.44,-0.39,P <0.05),the percentage body fat and S -TSH had positive relationship with plasma Ghrelin level (r =0.31,0.33,P <0.05).Conclusion The plasma Ghrelin level in the patients with hyperthyroidism is lower than healthy subjects,and its level is related with FT3 ,FT4 ,percentage of body fat and S -TSH,the detection of the above indicators has important value for the assessment of hyperthyroidism.

Purpose To investigate the diagnosis,differential diagnosis and clinical manifestation of primary plasma cell leukemia (PPCL) and lymphoma with increased plasma cell.Methods Through clinical data and cell morphology,flow cytometry (FCM),immunofixation electrophoresis and immunohistochemistry of EliVision two-step examination were used to analyze 7 cases of PPCL and 3 cases of lymphoma with increased plasma cell.Results All patients with PPCL and lymphoma with increased plasma cell presented with anemia,thrombocytopenia,fever,liver and spleen and lymph node swelling.The proportion of plasma cells in peripheral blood morphology were larger than 20％,accompanied by morphological abnormality.FCM of peripheral blood showed all 7 cases of PPCL expressed CD38 and CD138,CD56 expression in the 2 cases and CD20 in the 2 cases.The light chain (Lamda,Kappa) showed a monoclonal restricted expression,which was consistent with the diagnosis of PPCL.CD19 and CD45 were weakly positive in 3 cases of lymphoma with increased plasma cell,CD38 and CD138 were positive,and no restricted expression was found in light chain IgL,wich belonging to the immunophenotypes of normal plasma cells.Of 3 cases of light chain (Ig) without restrictive expression,2 of them were angioimmunoblastic T-cell lymphoma (ATCL) and 1 case was CD30-positive sinusoidal large B-cell lymphoma (CD30 + SLBCL) that confirmed by lymph node biopsy and pathological examination.Conclusion The PPCL and lymphoma with increased plasma cell have the same clinical manifestations and similar morphological characteristics of blood cells.The diagnosis of PPCL should be combined with immunoelectrophoresis and FCM,and the diagnosis of lymphoma with increased plasma cell needs to be confirmed by histological examination of lymph nodes.

Objective To investigate the clinical features,associated risk factors,and prognosis of gastrointestinal acute graft-ver-sus-host disease(GI-GVHD)after allogeneic hematopoietic stem cell transplantation(allo-HSCT).Methods The clinical data of 201 patients who underwent allo-HSCT in Affiliated Hospital of Xuzhou Medical University from January 2017 to July 2020 were retro-spectively analyzed,and grouped according to the occurrence of GI-GVHD.The factors associated with the occurrence of GI-GVHD were evaluated by univariate Logistic regression analysis,and the independent risk factors of their onset were evaluated by multivariate Logistic regression analysis,and further analyzed the effects of GI-GVHD on survival and prognosis.Results GI-GVHD occurred in 36 cases(17.9％)of the 201 patients who received allo-HSCT,with a median time to occur of 34(9-88)days and a median survival time of 228(21-1759)days,with an overall survival rate of 36.1％.The overall survival(OS)was significantly lower in patients who developed GI-GVHD at follow-up(36.1％vs 75.0％)compared with those without GI-GVHD,and the difference was statistically significant(P=0.004).Patients with GI-GVHD were characterized by persistent nausea and vomiting,abdominal pain,diarrhea,and gastrointestinal bleeding,often accompanied by damage to target organs such as the skin and liver.The results of univariate Logistic re-gression analysis showed that donor-recipient gender relationship(P=0.012),graft type(P=0.054),human leukocyte antigen(HLA)locus discrepancy(P=0.015),use of carbapenem antibiotics during pretreatment(P=0.029),use of carbapenems for more than 7 days during pretreatment(P=0.007),and early bloodstream infection(BSI,P=0.023)were influential factors in the occurrence of GI-GV HD.The results of multivariate Logistic regression analysis showed that female donor to male recipients(P=0.009,OR=8.866),non-related incompatible grafts(P=0.043,OR=16.532),carbapenem use for more than 7 days during pretreatment(P=0.023,OR=0.079),and early BSI(P=0.008,OR=0.165)were independent risk factors for the occurrence of GI-GVHD.Recipi-ent age,disease type,presence of underlying disease,graft type,duration of transplantation,the addition of antithymocyte globulin(ATG)to the pretreatment regimen,GVHD prophylaxis regimen,number of mononuclear cells(MNC)and CD34+cells returned,gran-ulocyte and megakaryocyte lineage time to reconstitution,and the occurrence of other types of GVHD were not risk factors for the occur-rence of GI-GVHD.The results of survival analysis showed that OS in the GI-GVHD group was significantly lower than that in the non-GI-GVHD group(36.1％vs 75.0％),and the difference was statistically significant(P=0.004).Conclusion Female donor to male recipients,non-related incompatible grafts,carbapenem use for more than 7 days during pretreatment,and early BSI may be the major risk factors for GI-GVHD,and the survival rate of patients with GI-GVHD after transplantation will be reduced.

The liver has a strong regenerative capacity that ensures patient recovery after hepatectomy and liver transplantation.The portal system plays a crucial role in the dual blood supply to the liver,making it a significant factor in hepatic function.Several surgical strategies,such as portal vein ligation,associating liver partition and portal vein ligation for staged hepatectomy,and dual vein embolization,have high-lighted the portal system's importance in liver regeneration.Following hepatectomy or liver trans-plantation,the hemodynamic properties of the portal system change dramatically,triggering regeneration via shear stress and the induction of hypoxia.However,excessive portal hyperperfusion can harm the liver and negatively affect patient outcomes.Furthermore,as the importance of the gut-liver axis has gradually been revealed,the effect of metabolites and cytokines from gut microbes carried by portal blood on liver regeneration has been acknowledged.From these perspectives,this review outlines the molecular mechanisms of the portal system's role in liver regeneration and summarizes therapeutic strategies based on the portal system intervention to promote liver regeneration.
