Objective To explore the potential of converting the chloramphenicol resistant clinical E. Coli isolates to chloramphenicol sensitive ones by employing external guide sequence(EGS) technique in vitro. Methods Recombinant plasmids with EGScat 1+2 and tetracycline resistant gene, named PAlterl EGScat1+2, was constructed. Routine Cacl 2 method was used to introduce recombinant plasmid into the chloramphenicol resistant clinical isolates E. Coli 4758. Colony PCR was used to test and A600 was used to detect growth rates in liquid and solid culture of various concentrations of chloramphenicol. Results The chloramphenicol resistant clinical isolates E. Coli 4758 grew well in chloramphenicol(35 ?g/ml, 70 ?g/ml, 105 ?g/ml, 170 ?g/ml) plates whereas the transformants tE4758 with PAlter1 EGScat 1+2 failed to grow in these concentrations, which indicated its resistance to the chloramphenicol was reversed. Conclusions EGS molecules are able to convert the drug resistance in clinical E. Coli isolates in vitro.

Objective:To investigate the clinical manifestation and determine the distribution of pathogens and their characteristics of drug susceptibility to bloodstream infections (BSIs), and provide evidence for clinical anti-infection treatments after renal transplantation.
Methods:Totally 81 episodes of BSIs occurred in 71 patients between July 2003 and June 2013. We retrospectively analyzed the pathogens and their drug susceptibility characteristics with BD microbiological assay system. We also collected the clinical and laboratory data of the patients . Results:The main pathogens were gram negative bacteria (67.90%), followed by gram positive bacteria (28.40%) and fungi (3.70%). The most common gram negative bacillus was Escherichia coli.While for gram positive bacteria, the main bacillus was coagulase-negative staphylococci. The gram negative bacteria were relatively sensitive to aminoglycosides and carbapenem. The gram positive bacteria were sensitive to glycopeptides and oxazolidone.
Conclusion:The clinical manifestations included high body temperature, onset in the early period after kidney transplantation and high mortality. Though gram positive coccus plays an important role, most infections are caused by gram negative bacteria in BSIs after the renal transplantation. The antibiotic resistant rate for gram negative bacteria is very high as well as gram positive bacteria.

Objective To investigate the epidemiological characteristics and factors of hemorrhagic fever with renal syndrome (HFRS) during 1958 to 2007 in Fuyang.Methods Descriptive study method was used to analyze the epidemiological characteristics of hemorrhagic fever with renal syndrome.The incidence peak of hemorrhagic fever with renal syndrome was computed by using rotundity distribution.The correlation was analyzed between incidence and virus index by Pearson correlation.Results 40 002 HFRS cases was reported during 1958 to 2007 in Fuyang and 2381 cases were dead.The average incidence and fatality rate of HFRS were 11.99 per 100 thousand and 5.95 percent respectively.Eight counties all had cases.Yingshang county had the highest cases and Jieshou city had the highest fatality rate.Since 1958,there're 4 incidence peak in Fuyang.The period of high incidence was during November to January of next year and the peak of incidence rate was on December 13.Indoor density and field density of mouse were 9.84 percent and 7.91 percent respectively.Virus rate of indoor and field of mouse were 9.21 percent and 6.99 percent respectively.During 1984 to 2007,the correlation coefficient between virus index and incidence was 0.58.In room brown mouse was the most before 2000,but then house mouse become the most.In open country heavy line Japanese fieldmouse is the most mouse all the time.Conclusions In Fuyang,the focus of HFRS is exist widely.Density and virus rate of mouse will directly affect the incidence.So surveillance among mouse should be strengthened.

OBJECTIVE: To evaluate clinical characteristics, pathogens, treatment regimens and outcomes in patients with bloodstream infections (BSIs) after solid organ transplantation. METHODS: Clinical data of ninety six cases of BSI were analyzed retrospectively to identify the pathogens and the origin of infection, and to evaluate comprehensive treatment and the causes of success or failure. RESULTS: All 96 patients underwent the comprehensive treatments, including suspending administration of immunosuppressants and starting administration of appropriate antibiotics. The clinical characteristics of patients with BSIs after solid organ transplantation were atypical. The pathogens were various and seriously multi-drug resistant, which led to a high mortality. Among them 57 cases recovered, but the BSI-related mortality rate was 40.6%. CONCLUSION Stopping the administration of immunosuppressants, reasonable use of antibiotics, nutritional support and protecting the function of organs as soon as possible were of the greatest importance among of the various treatment plan. Avoidance of all kinds of infection in the first place is most important.

Objective To investigate the risk factors of bloodstream infection-related death after liver transplantation.Methods The retrospective case-control study was adopted.The clinical data of the 107 patients with bloodstream infection from 365 liver transplantation patients who were admitted to the Third Xiangya Hospital of Central South University (220 patients) and South Central Hospital Affiliated to Wuhan University (145 patients) from January 1,2002 to December 31,2015 were collected.The patients received modified piggyback liver transplantation.The second or third generation celphalosporin or carbapenems antibiotics were preventively used against infection according to the bacterial culture results before surgery,and the immune inhibitor basic program after surgery was FK506 + prednisone.The observation indicators included:(1) the bloodstream infection status after liver transplantation:incidence of bloodstream infection,frequency of bloodstream infection,inadequate antiinfection treatment,primary infection position,microorganism infection type,bacterial culture results and bloodstream infection-related mortality.(2) The risk factors of blood stream infection-related death after liver transplantation in univariate and multivariate analyses in cluded:the gender,age,resource of donor,usage of immune inhibitor,time between infection and liver transplantation,infection temperature,primary infection position(intraperitoneal or biliary infection),pathogenic microorganism type,nosocomial infection,inadequate antibiotic usage,serum creatinine level,serum albumin (Alb) level,white blood cell (WBC) in peripheral blood,lymphocyte in peripheral blood,platelet (PLT) in peripheral blood and septic shock indexes.The patients were followed up by outpatient examination and telephone interview up to January 31,2016,the follow-up contents included the survival status of the patients,vital signs,using status of immune inhibitor,immune inhibitor concentration,blood routine,biochemical indexes,surgery,other infection-related complications and acute rejection.Continuous variables with normal distribution were represented as ~ ± s.The univariate analysis was done by the Chi-square test.The multivariate analysis was done by the Logistic regression model.Results (1) The bloodstream infection status after liver transplantation:186 bloodstream infections were happened in 107 patients undergoing liver transplantation,with a total incidence of bloodstream infection of 29.32％ (107/365).The incidence of bloodstream infection was 28.18％ (62/220) in the Third Xiangya Hospital of Central South University and 31.03％ (45/145) in the South Central Hospital Affiliated to Wuhan University,with no statistical difference (x2=0.186,P ＞0.05).Of 107 patients,56 patients had once bloodstream infection,31 had twice bloodstream infection and 20 had three times or more bloodstream infection (frequency of the most bloodstream infection was 6).The inadequate anti-infection treatment was applied to the 41.12％ (44/107)of patients with liver transplantation and bloodstream infection.The number of patients with primary infection positions in abdomen,lung,urethra,intravascular catheter and unknown sites were 40,39,3,1 and 24,respectively.The Gram positive bacteria,Gram negative bacteria,fungus and mixed infection of microorganism infection type were detected in 28,24,4 and 51 patients,respectively.There were 102 patients with nosocomial infection.Bacteria culture results in 186 strains of blood sample illustrated:84 strains were Gram positive bacteria as major pathogenic bacteria,among which enterococcus (31 strains) and staphylococcus aureus (23 strains) were dominant strains.The bloodstream infection-related mortality was 37.38％ (40/107),including 35 patients dying of septic shock.(2) The univariate analysis showed that the gender,resource of the donor,infection temperature,type of microorganism,serum creatinine level,serum Alb level,WBC in peripheral blood,PLT in peripheral blood and septic shock were the risk factors affecting bloodstream infection-related death after liver transplantation (x2=5.801,5.920,13.047,12.776,11.366,7.976,25.173,9.289,51.905,P ＜0.05).The multivariate analysis showed that serum Alb level ＜ 30 mg/L and septic shock were the independent risk factors affecting bloodstream infection-related death after liver transplantation (OR =5.839,44.983,95 ％ confidence interval:1.145-29.767,12.606-160.514,P ＜ 0.05).Conclusion It is prone to happen bloodstream infection after liver transplantation,and serum Alb level ＜ 30mg/L and septic shock are the independent risk factors affecting bloodstream infection-related death after liver transplantation.

OBJECTIVE: To explore the risk factors for septic shock in patients with solid organ transplantation and complication of bacteremias. METHODS: Clinical data of 98 solid organ transplant cases with complication of bacteremias were retrospectively studied. All episodes of bacteremias met the CDC criteria. Six possible risk factors contributing to septic shock were evaluated by univariate analysis and multivariate logistic regression analysis. RESULTS: Among the 98 patients, 133 times of bacteremias have been reported and 39 patients developed septic shock. Among the 39 patients with septic shock, 43.5%, 38.5%, 15.4% and 2.6% of bacteremias were induced by multiple bacteria, gram-negative bacteria, gram-positive bacteria and fungi, respectively. The lung was the main source of bacteremias (41.8%), followed by intraabdominal/ biliary focus (24.5%). Risk factors for developing septic shock included the bacteremias happened in the 2nd to 8th week post transplant (P=0.014), polymicrobial etiology (P=0.001), intra-abdominal/ biliary focus (P=0.011), and liver transplant (P=0.002). Only bacteremias occurred in the 2nd to 8th week post transplant and polymicrobial etiology were significant risk factors by multivariate analysis. CONCLUSION Risk factors for developing septic shock in bacteremias after SOT are early-onset (the 2nd-8th week post transplant) and polymicrobial etiology.

OBJECTIVE: To investigate the possible risk factors for death among liver or kidney recipients with bloodstream infections (BSIs). METHODS: A retrospective study of 138 episodes of bloodstream infections documented in 103 patients was conducted to assess potential risk factors for mortality. The risk factors were identified by logistic regression analysis. RESULTS: The mean age of the patients was 12-66 (42.3±12.7) years. The majority of infections were nosocomial (78.6%). The BSIs-related mortality rate was 39.8% (41/103). The following variables were identified as risk factors for BSIs-related mortality by univariate analysis: intraabdominal/ biliary focus (P=0.003), polymicrobial infection (P<0.001), liver transplant (P<0.001), platelet count <50000/mm3 (P<0.001), and septic shock (P<0.001). Platelet count < 50000/mm3 (P=0.002) and septic shock (P<0.001) showed significantly difference between the mortality group and the survival groups in the multivariate logistic regression analysis. CONCLUSION Decreased platelet count and septic shock are risk factors for increased

Acute respiratory distress syndrome (ARDS) is a critical disease with high mortality, and currently there is no specific treatment. ARDS is characterized by refractory hypoxemia secondary to pulmonary edema, but the underlying mechanism is not yet fully understood. Alveolar edema fluid is mainly actively transported and reabsorbed by sodium-water transport system. The sodium pump (Na +-K +-ATPase-mediated Na + transport) on the basal side of type Ⅱ alveolar epithelial cells (ATⅡ) is the main driving force for pulmonary edema clearance. Na +-K +-ATPase regulation is affected by many regulatory factors through a variety of ways, among which "long-term regulation" mechanism plays an important role, including positively regulating the gene transcription and protein expression of Na +-K +-ATPase. Na +-K +-ATPase can also be degraded by ubiquitin-proteasome pathway (UPP) and autophagy lysosome pathway to affect its abundance and enzyme activity, meanwhile, Na +-K +-ATPase α1 plays a key role in sodium water transport. We review the "long-term regulation" mechanism of Na +-K +-ATPase related pathways in pulmonary edema clearance and explore the possibility of new therapies for ARDS based on this mechanism, so as to provide new targets for the treatment of ARDS.

OBJECTIVES: Liver transplant recipients have a high rate of postoperative infection, and identification of patients at high risk for bacterial and fungal infections will help prevent disease and improve long-term outcomes for them. This study aims to understand the composition, distribution, prognosis of bacterial and fungal infections within 2 months after liver transplantation and to analyze their risk factors. METHODS: The data of pathogen composition, distribution, and prognosis of bacterial and fungal infections among liver transplant recipients in the Third Xiangya Hospital of Central South University from May 2020 to October 2021 were collected, and the risk factors for these infections were analyzed. RESULTS: A total of 106 episodes of bacterial or fungal infections occurred in 71.4% of liver transplant recipients (75/105). Gram-negative bacteria were the dominant pathogenic bacteria (49/106, 46.2%), followed by Gram-positive bacteria (31/106, 29.2%). The most common Gram-negative bacterium was Acinetobacter baumannii (13/106, 12.3%). The most common Gram-positive bacterium was Enterococcus faecium (20/106, 18.9%). The most common infections were pulmonary (38/105, 36.2%) and multiple site infections (30/105, 28.6%). Six (6/105, 5.7%) patients with infections died within 2 months after liver transplantation. Univariate analysis showed that the model for end-stage liver disease (MELD) score ≥25, antibiotic use within half a month before transplantation, infections within 2 months prior to transplantation, intraoperative red blood cell infusion≥8 U, indwelling urinary tract catheter ≥4 days after transplantation, and the dosage of basiliximab use ≥40 mg were associated with infections. Multivariate logistic regression analysis revealed that only infections within 2 months prior to transplantation (OR=5.172, 95% CI 1.905-14.039, P<0.01) was an independent risk factor for bacterial and fungal infections after liver transplantation. Postoperative bacterial and fungal infections were reduced in liver transplant recipients receiving basiliximab ≥40 mg (OR=0.197, 95% CI: 0.051-0.762, P<0.05). CONCLUSIONS The incidence of bacterial and fungal infections is high in the early stage after liver transplantation, and the mortality after infection is significantly higher than that of non-infected patients. The most common infection is respiratory infection, and the dominant pathogens is Gram-negative bacteria. Patients infected within 2 months prior to liver transplantation are prone to bacterial and fungal infections. Standard use of basiliximab can reduce the incidence of infections after liver transplantation.
