Objective:To explore the predictive value of the serum C-reactive protein (CRP)/albumin (ALB) ratio (CAR) for organ damage in tsutsugamushi disease.Methods:The clinical data of 166 patients with tsutsugamushi disease admitted to the First Affiliated Hospital of Wenzhou Medical University from January 1, 2010 to December 31, 2020 were retrospectively analyzed. The patients were divided into the organ damage group (72 cases) and non-organ damage group (94 cases) according to the organ damage criteria. The general data and laboratory test results of the two groups of patients were compared. The significant indicators of univariate analysis were analyzed by multivariate logistic regression analysis. The receiver operating characteristic (ROC) curve and area under the curve (AUC) were used to analyze the predictive value of CAR for organ damage in patients with tsutsugamushi disease.Results:There were no significant differences in age, sex, days of fever, and admission body temperature between the organ damage group and non-organ damage group ( P>0.05). However, the body mass index, acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ), sequential organ failure assessment (SOFA), length of hospital stay, hospitalization expense, percentage of neutrophils (NEUT), lymphocyte count, procalcitonin, CRP, and CAR in the organ damage group were significantly higher than those in the non-organ damage group ( P<0.05), and ALB was significantly lower than that in the non-organ damage group ( P<0.05). Multivariate logistic regression analysis showed that APACHEⅡ( P=0.039), NEUT ( P=0.003), and CAR ( P=0.011) were independent risk factors for tsutsugamushi disease complicated by organ damage. The ROC curve showed that the AUCs of APACHEⅡ, NEUT, and CAR were 0.655, 0.716, and 0.727, respectively. When the cut-off value of CAR was 2.86, the sensitivity was 55.6%, and the specificity was 79.8%. Conclusions:Elevated CAR is an independent risk factor for tsutsugamushi disease complicated with organ damage and can be used as an important indicator to evaluate the presence or absence of organ damage in patients with tsutsugamushi disease.

From September to November 2019, three patients with Hornet stings were admitted to hospital with acute anaphylaxis and various degrees of organ dysfunction. After hemoperfusion combined with continuous hemodialysis and hormone pulse therapy, 1 patient was successfully treated and 2 patients were not cured. Bee Stings can cause systemic allergic reactions and toxic reactions. In severe cases, acute anaphylaxis, rhabdomyolysis, intravascular hemolysis, abnormal coagulation, and acute liver and kidney injury may occur, myocardial damage and other multi-organ function damage or even failure, is a clinical acute and critical illness, mortality is higher. Through the analysis of the diagnosis and treatment process of these 3 cases, the experience is summarized: the Bee sting should be treated as soon as possible, the early prevention and treatment of multiple organ dysfunction, the choice of accurate blood purification and comprehensive treatment, can effectively improve the prognosis, increase the success rate of treatment.

Objective To investigate the effects of histone deacetylase inhibitors trichostatin A (TSA) on acute lung injury in septic mice.Methods Septic mice model was induced by cecal ligation and puncture(CLP).Ninty male BALB/c mice of clean grade were randomly(random number) divided into six groups(n=15),namely sham operation group,CLP group,CLP+DMSO group,CLP+TSA 1 mg group,CLP+TSA 5 mg group,and CLP+TSA 10 mg group.TSA(1 mg/kg,5 mg/kg,10 mg/kg) was administrated 12 hours before operation by intraperitoneal injection.And mice in sham group were only treated with laparotomy without CLP,and 24 h later,all survived mice were sacrificed to obtain specimens.ELISA method was employed to detect the concentrations of TNF-α and IL-1β in BALF.The lung wet/dry ratio was calculated.Histopathology changes of lung tissues were observed under light microscope.Lung tissue cell apoptosis was detected by TUNEL method.Caspase-3,Caspase-9 and CytC were assayed by Western blotting.The survival rate of mice in each group was calculated by additional 120 mice.Data were analyzed by SPSS 23.0.Statistical analyses were performed using independent sample t-test to compare between two groups or one-way analysis of variance test to compare among muhiple groups.The survival rate of mice was analyzed by univariate analysis using log-rank test.Results The lung W/D(P=0.021),the concentrations of TNF-α(P=0.000 1)and IL-1β(P=0.000 6)in BALF,puhnonary pathological change(P=0.001 6),lung tissue cell apoptotic index(P=0.000 9),the levels of apoptosis proteins (P＜0.05) in CLP group were higher than those in sham group,while survival rate (P=0.000 1) in CLP groups was lower than that in sham group.Compared with DMSO,the TSA significantly reduced the lung W/D,the levels of TNF-α.IL-1β in BALF,pathologic changes of lung tissue,lung tissue cell apoptotic index and the levels of apoptosis proteins in septic mice(P＜0.05).The increase in survival rate (P=0.007 2) associated with TSA(10 mg/kg)administration.Conclusion TSA exerts protective effects through attenuating pro-inflammatory cytokines and lung tissue cell apoptosis in sepsis induced acute lung injury in mice.

Objective: To compare the predictive value of PSS, APACHEII, SAPSII and SOFA in the prognosis evaluation of acute poisoning. Methods: Clinical data (including PSS score, APACHEII score, SAPSII score and SOFA score, within 24 hours after admission) of 231 acute poisoning patients admitted to the emergency intensive care unit EICU of our hospital from January 2015 to October 2016 was retrospectively analyzed. The patients were divided into the survival group and the dead group according to the 28-day clinical outcomes, comparing the differences of clinical data in each group. To analyze the correlation between PSS score, APACHEII score, SAPSII score and SOFA score in each group, comparing the value and the area under the ROC curve of four scoring systems and evaluate the predictive value of the four scoring systems. Results: Comparing with the survival group and the dead group, PSS score, APACHEII score, SAPSII score and SOFA score were significantly different (P<0.01) . PSS score, APACHEII score, SAPSII score and SOFA score were significantly positive correlation (P<0.01) , the area under the ROC curve (AUC) of the four scoring systems were 0.833, 0.887, 0.843 and 0.843 respectively. The area under the ROC curve (AUC) of APACHEII score was higher than PSS score, SAPSII score and SOFA score, the difference was statistically significant (z=2.351, 2.317, 2.217; P=0.019, 0.021, 0.027) , there was no significant difference in the area (AUC) between the three scoring curves (P>0.05) . The cutoff value (cut-off) , sensitivity, specificity and accuracy rates of PSS score, APACHEII score, SAPSII score and SOFA score were (2.5, 93.1%, 50.9%, 61.5%) , (14.5, 82.8%, 75.7%, 77.48%) , (31.5, 77.6%, 76.90%, 77.08%) , (5.5, 77.60%, 74.60%, 75.35%) . Conclusion PSS score, APACHEII score, SAPSII score and SOFA score can evaluate the prognosis of patients with acute poisoning, but the APACHEII score is better than the other three scoring systems in evaluating the prognosis for its evaluation ability and accuracy rate.

Objective To explore the clinical value of procalcitonin (PCT)in the disease severity and prognosis of patients with sepsis,and the relationship between PCT and acute physiology and chronic health evaluation Ⅱscore (APACHEⅡscore).Methods Clinical data (including the value of PCT,the count of the white blood cell WBC and the percent of neutrophils percentage Neut%,APACHEⅡ score,et al,within 24 hours after admission)of 109 sepsis patients admitted to the emergency department (including the general ward and emergency intensive care unit EICU)and infections department of our hospital from January 1st 2013 to December 31st 2014 were retrospectively analyzed.The patients were divided into several groups according to the patients condition (the sepsis group,the severe sepsis group and the septic shock group),the clinical outcomes (the survival group and the dead group ),and multiple organ dysfunction syndrome MODS (the MODS group and the non-MODS group),comparing the differences of all markers in each group;to analyze the correlation between PCT and APACHEⅡ score;to assess the value of PCT,APACHE Ⅱ score and APACHE Ⅱ score +PCT for prognosis and multiple organ dysfunction syndrome of patients with sepsis;to have a understanding of the independent effect of PCT on the prognosis andthe factors of prognosis in patients with sepsis.Results The value of PCT,APACHEⅡ score in sepsis group was lower than the severe sepsis group and the septic shock group,also the severe sepsis was lower than the septic shock group,and each group was significantly different (P <0.05).Compared with the septic shock group,the count of WBC of sepsis group was significantly lower (P <0.05).Also the dead group compared with the survival group,the APACHEⅡ score was significantly increased (P <0.01),but the values of PCT,WBC,Neut% were not significantly different.The values of APACHEⅡ score,WBC, Neut%,PCT in the non-MDOS group were significantly lower than those in the MODS group (all P <0.05).The relationship between the values of PCT and APACHEⅡ score was significantly correlated (rs=0.403,P <0.01 ).Using the receiver operating characteristic curve (ROC ) for evaluating the prognosis,the area under curve (AUC)of PCT,APACHE Ⅱ score and the PCT +APACHE Ⅱ score respectively were 0.617,0.899,0.917,and the last two were significantly better (all P <0.01),also the cut-off,sensitivity and specificity of PCT,APACHE Ⅱ score were respectively (3.40 ng/mL, 88.24%,38.04%),(20 scores,94.12%,81.52%).As the same to evaluating MODS,the AUC of PCT,APACHEⅡ score and APACHE Ⅱ score +PCT respectively were 0.824,0.796,0.871,the assessed value between PCT and APACHEⅡ score,between PCT and APACHEⅡ score +PCT were not significantly different;also the cut-off,sensitivity and specificity of PCT,APACHEⅡ score respectively were (7.26 ng/mL,88.24%,63.79%), (17 scores,64.71%,87.93%).The COR and AOR of PCT for the prognosis were respectively 1.008,1.014,and gender and APACHE Ⅱ score were the two independent risk factors for the prognosis in patients with sepsis.Conclusions The value of PCT and APACHEⅡ score could evaluate the severity of illness in sepsis patients,and the three were positive correlations.APACHEⅡ score,APACHEⅡ score +PCT had a significantly higher prognostic value than PCT,and PCT could not be a independent marker.But for assessing the MODS in patients with sepsis,the assessed value of PCT,APACHEⅡ score,APACHEⅡ score +PCT were medium.Gender and APACHEⅡ score were the two independent risk factors for the prognosis in patients with sepsis.

OBJECTIVETo investigate the effect of hemoperfusion on paraquat-Induced kidney inflammation injury of rabbit and the mechanism of it.

METHODS60 male rabbits were randomly divided into 4 groups, the normal control group (n=6, the rabbits were given NS by gavage) , blank control group (n=18, he rabbits were given 2 hours hemoperfusion once within 1 hour after given NS by gavage), paraquat poisoning group (n=18, the rabbits were given 50 mg/kg 20% paraquat solution by gavage) , hemoperfusion treatment group (n=18, the rabbits were given 2 hours hemoperfusion once within 1 hour after 20% paraquat solution espoused). The last 3 groups were divided into 3 observation time groups (1, 3, 7 day), contained 6 rabbits each group. On days 1, 3, 7 all groups rabbits were anesthetized and sacrificed, and their kidney tissues collected. The levels of NF-κB mRNA by RT-PCR, and the expression of NF-κB protein was measured by Western blotting,The expression levels of TNF-α, IL-6, iNOS measured by chemical colorimetric method to to observe inflammatory injury.

RESULTSCompared with the normal control group rabbits, there were no changes in the TNF-α, IL-6, iNOS, NF-κB mRNA and protein of blank control group (P>0.05), while the expression of TNF-α, IL-6, NF-κB mRNA and protein in the kidney tissue of PQ group and were significantly increased (P<0.05). The pathological results of kidney tissues were no abnormalities onnormal control group and blank control group.

OBJECTIVETo find out a method which can assess the prognosis of patients with Acute Organophosphate Poisoning objectively and increase the successful ratio of treatment by investigating relevant factors on the prognosis of the patients with Acute Organophosphate Poisoning.

METHODSWe retrospected 116 patients with Acute Organophosphate Poisoning who were treated in our hospital's emergency room from April 2006 to March 2014. According to the outcome of patients, we distributed the patients to death group and survival group, compared the clinic data and using multivariate analysis with Logistic regression to prognosis factors.

RESULTS116 cases of acute organophosphate poisoning patients died in 23 cases, improved in 93 cases. Death group patients' APACHE-II score are higher than whose in the survival group (P < 0.05). Compared with the survival group, patients' body temperature, blood pressure, pH, GCS index were lower in the death group (P < 0.05) and Cr, WBC, ALT, AST, CK-MB, blood glucose, blood lactic acid, heart rate were higher in the death group (P < 0.05), there were significant difference between two groups with statistical.Low blood pressure, lower GCS score, hyperglycemia and high white blood cell count, were independent risk factors of poor prognosis, and hypotension was maximum value of all the factor (OR = 54.22).

CONCLUSIONAPACHE II prognostic scoring system can be accurately response, vital signs, white blood cell count, pH, serum creatinine, GCS score and serum sodium value which in this system may be associated with prognosis. To evaluate the severity and prognosis of illness Blood glucose, ALT, AST, CK-MB's rising also has certain value.

Objective To evaluate the relationship between changes in B-type natriuretic peptide(BNP) and cardiac troponin I(cTnI)levels and prognosis of critically ill patients with sepsis. Methods This study retrospectively reviewed the clinical data of 75 patients with severe sepsis and septic shock admitted into Emergency Intensive Care Unit(EICU)of the First Affiliated Hospital of Wenzhou Medical University in Zhejiang Province. According to the severity of the cases,they were divided into two groups:severe sepsis group(34 cases)and septic shock group(41 cases),and based on the difference in prognosis,they were divide into survivor group(32 cases) and non-survivor group(43 cases). Electrocardiogram(ECG)was performed within 24 hours after admission in all the patients. Acute physiology and chronic health evaluation Ⅱ(APACHEⅡ)score and biochemical markers showing organ dysfunctions as BNP, cTnI, creatine kinase (CK), creatine kinase MB mass(CK-MB), and lactate were compared between severe sepsis and septic shock groups and between survivor and non-survivor groups. Results The septic shock group had significantly higher baseline BNP,cTnI,lactate and APACHE Ⅱscore and mortality rate than those in severe sepsis group〔BNP(μg/L):1.90(1.08,2.79)vs. 0.41(0.31,0.75),cTnI (μg/L):1.15(0.92,1.28)vs. 0.58(0.40,0.79),lactate(mmol/L):6.63±3.72 vs. 3.28±1.66,APACHEⅡscore:26.00(24.00,28.00)vs. 21.50(20.00,29.25),mortality rate:70.73%vs. 41.18%,P<0.05 or P<0.01〕. Compared with survivor group,the ages of non-survivor group were older with more males and higher BNP,cTnI,lactate and APACHEⅡscore〔males(cases):30 vs. 13,age(years old):66.49±14.97 vs. 58.19±17.05,BNP:1.60(0.62, 2.51)vs. 0.57(0.37,1.79),lactate:4.10(3.00,9.00)vs. 3.10(2.13,4.18),cTnI:1.02±0.49 vs. 0.62±0.37, APACHE Ⅱ score:28.00(25.00,30.00)vs. 21.00(20.00,25.75),P<0.05 or P<0.01〕. However,there were no statistically significant differences in the levels of CK and CK-MB between the above compared groups(both P>0.05). The patients' ECGs had no obvious changes. Conclusions High plasma BNP and cTnI levels in patients with sepsis may suggest myocardial damage and relatively bad prognosis. The examination of BNP and cTnI levels may help clinicians to early detect the high-risk patients with septic cardiac dysfunction and assess their prognoses.
