Objective To compare the strong ion gap (SIG) and liver and kidney function index predicting the prognosis of acute paraquat poisoning patients.Methods Retrospective study with a total of 148 cases from 2006 to 2013 who were diagnosed by paraquat poisoning,according to the prognosis they are divided into survival group and death group.Compared with the early SIG,ALT,AST,Cr,BUN index level to analyze with the odds ratio (ORs) and established ROC curve to conform which is more effective on the prognosis of patients with paraquat poisoning.Results The abnormal index of glutamic pyruvic transaminase (ALT) (x2=10.257,P =0.001),glutamic oxalacetic transaminase (AST) (x2=9.109,P =0.003),creatinine (Cr) (x2=10.257,P =0.021),blood urea nitrogen (BUN) (x2=10.257,P ＜ 0.01) indicated a higher risk of death than the normal index,SIG showed higher ORs for fatality than ALT,AST,Cr,BUN (P ＜ 0.05).In the ROC curve,the area under the curve of the SIG,ALT,AST,Cr,BUN on the prognosis of fatality were 0.822,0.708,0.724,0.603,0.625.Conclusions With early SIG and ALT,AST,Cr,BUN level increased,the risk of death will increase in paraquat poisoning patients,and SIG is a more effective marker than index of kidney and liver function on the prognosis of death.

Objective To explore the related risk factors of cerebral hemorrhage complicated with stress ulcer (SU). Methods The clinical data of 1 185 patients with cerebral hemorrhage admitted to Department of Emergency Medicine of Nanjing General Hospital from March 2006 to March 2014 were retrospectively analyzed. Patients were divided into two groups according to whether patients complicated with SU or not. Data was collected within 8 hours after admission in two groups including gender,age,amount of bleeding,the bleeding site (basal ganglia,thalamus, brainstem,brain lobe,ventricle,subarachnoid,and cerebellum),disturbance of consciousness,acute physiology and chronic health evaluationⅡ(APACHEⅡ)score,systolic blood pressure(SBP),history of hypertension,and history of cerebral hemorrhage. The statistically significant risk factors found using univariate analysis was selected and was analyzed to find independent risk factors with multivariate logistic regression analysis. The receiver operating characteristic curve (ROC curve)was plotted to analyze the independent risk factors and evaluate their power of test. Results 1 185 patients with cerebral hemorrhage were enrolled in the study,293 cases occurred SU,accounting for 24.7%,and 892 cases without SU,which accounted for 75.3%. As shown by univariate analysis,risk factors for cerebral hemorrhage complicated with SU included age,amount of bleeding,the bleeding site,disturbance of consciousness,APACHEⅡscore,SBP. As to the site of bleeding,brain,thalamus,brainstem hemorrhage complicated with SU were higher proportion,45.3%(43/95),39.1%(63/161),36.9%(48/130),which were significantly higher than those of the lobes of the brain 〔26.2% (33/126)〕,cerebellum 〔18.8% (15/80)〕,basal ganglia〔16.1%(78/485)〕,arachnoid the inferior vena cava 〔12.0% (13/108)〕. Multivariate logistic regression analysis showed that amount of bleeding 〔odds ratio (OR)=3.305,P=0.001,95%confidence interval (95%CI)2.213-48.634〕,the bleeding site (OR=1.762,P=0.008,95%CI 0.123-2.743),SBP (OR=1.223,P=0.034,95%CI 0.245-2.812) were independent risk factors of cerebral hemorrhage complicated with SU. The area under the ROC curve (AUC)of amount of bleeding and SBP were 0.846 and 0.597,suggesting that amount of bleeding has moderate diagnostic value and SBP has low diagnostic value. Conclusions Cerebral hemorrhage patients with large amount of bleeding,the bleeding site in the ventricle,thalamus or brainstem,high SBP are of great risk. We should lower blood pressure and give preventive treatment for SU as soon as possible.

Objectives:To investigate the risk factors for acute liver injury (ALI) in patients after resuscitation from cardiac arrest and their influence on prognosis.Methods:The clinical data of patients after cardiopulmonary resuscitation in our department from January 2015 to January 2018 were analyzed. According to whether ALI occurred, the selected patients were divided into the ALI group and non-ALI group. The basic situation of the two groups of patients and the occurrence of shock and cardiac insufficiency after cardiac arrest were investigated. Kaplan-Meier method was used to analyze the effect of ALI on the 1-year survival of patients. The 28-day mortality and neurological recovery were observed in patients in the ALI group. Multivariate logistic regression was used to analyze the risk factors for ALI.Results::There were 54 patients in the ALI group and 158 patients in the non-ALI group. The patients in the ALI group needed a longer time to recover spontaneous circulation [19 (10-27) min, P=0.015], and the overall condition (SOFA score, acidosis, and lactic acid) were more serious. The incidences of shock and heart failure after cardiac arrest in the ALI and non-ALI groups were 74% and 55%, and 89% and 70%, respectively. The 1-year cumulative survival rate of patients in the non-ALI group was significantly higher than that of the ALI group ( P=0.043). The longer the duration of ALI, the higher the incidence of poor prognosis. The time to resume spontaneous circulation ( OR=3.762; 95% CI: 2.347-5.098) and heart failure ( OR=4.272; 95% CI: 2.943-5.932) after cardiac arrest were associated with ALI in patients after cardiopulmonary resuscitation (both P<0.05). Conclusions:The time to resume spontaneous circulation after cardiac arrest and heart failure after cardiopulmonary resuscitation are risk factors for ALI, and the occurrence of ALI increases patient’s mortality.

Objective:To investigate the clinical efficacy of ultrasound-guided percutaneous radiofrequency ablation in the treatment of ectopic pregnancy.Methods:A retrospective analysis was performed on 8 patients with ectopic pregnancy admitted to the First Affiliated Hospital of Zhengzhou University from January 2018 to January 2020, all of whom underwent ultrasound-guided percutaneous radiofrequency ablation. Contrast ultrasonography was performed immediately after the operation to observe the changes of pregnancy sac. The length of hospital stay, mass absorption time and menstrual recovery time of the patients were recorded. Postoperative complications and serum human chorionic gonadotropin (HCG) negative conversion time were observed. At 3 months after the operation, hysterosalpingography was performed 3-7 days after the menstruation to observe the patency of the fallopian tubes, all patients were followed up for 1 year to observe the postoperative intrauterine pregnancy and re-ectopic pregnancy.Results:All the 8 patients were successfully treated with radiofrequency ablation, and postoperative ultrasonography showed that the mass remained unenhanced. The length of hospital stay was (3.0±0.8)d. The packet absorption time was (32.4±14.3)d. The recovery time of menstruation was (39.6±2.7)d. There were no serious complications.Blood HCG levels decreased rapidly within a week, and all returned to normal level of non-pregnancy 2-3 weeks after the operation. Three months after the operation, the salpingogram showed that the fallopian tubes were recanalized in 3 patients. After a follow-up of 1 year, 1 patient had a natural intrauterine pregnancy, and there was no case of recurrent ectopic pregnancy.Conclusions:Ultrasound-guided percutaneous radiofrequency ablation is effective in the treatment of ectopic pregnancy with minimal trauma and rapid recovery, and can retain the reproductive ability of patients to some extent, which is worth popularizing in clinical application.

Objective Acute coronary syndrome ( ACS) is frequently accompanied by chronic comorbidities , which may se-riously affect its prognosis .This study aims to investigate the value of the Charlson Comorbidity Index ( CCI) in predicting the outcome of ACS by assessing the impact of individual and post-weighted-assignment comorbid conditions of the disease . Methods We retro-spectively analyzed the clinical data on 1 096 cases of ACS treated in Jinling Hospital from January 2010 to March 2014 .We reviewed their general information , clinical presentations , complications , and previous treatments , calculated CCI , and used in-hospital mortali-ty as the index for judging the prognosis . Results Of the 1 096 patients, 73%were males (aged 64.2 ±12.9 years), 27% were females (aged 72.1 ±12.6 years), and 46.8% had comorbidities. Of the diseases included in the CCI system , previous myocardial infarction was the most frequent comorbidity (18.0%), followed by diabetes mellitus ( 14.7%), moderately to severe renal disease (7.1%), cerebrovascular disease (6.0%), and chronic lung dis-ease (6.0%).Single factor analysis revealed statistically significant differences between different CCI groups in such clinical indicators as history of coronary artery disease , history of hypertension , time between symptom onset and admission , hemodynamics , drugs adminis-tered (aspirin, P2Y12 blockers, ACEI/ARB or statins), and reperfusion therapy (P<0.05).Logistic regression analysis showed the strongest predictors of in-hospital mortality were heart failure (OR 1.88, 95%CI:1.57-2.25), metastatic tumor (OR 2.25, 95%CI:1.60-3.19), renal disease (OR 1.84, 95% CI:1.60-2.11), and diabetes mellitus (OR 1.35, 95% CI:1.19-1.19). Receiver operating characteristic curve analysis manifested that either CCI with age or CCI with age and gender was superior to CCI a -lone in predicting in-hospital mortality of ACS patients (AUC 0.761 [95%CI 0.748-0.773] and 0.756 [95%CI:0.743-0.768] vs 0.670 [95%CI:0.656-0.685]). Conclusion Heart failure, diabetes mellitus, renal disease, and metastatic tumors contrib-ute to the in-hospital mortality of ACS patients .CCI together with age and gender may help to assess the prognosis of the disease .

Objective After acute craniocerebral trauma , to a certain extent , arterial blood lactate and lactate clearance rate reflect the illness severity .We aimed to investigate the prognosis value of arterial blood lactate and lactate clearance rate in patients with craniocerebral trauma . Methods 94 cases with craniocerebral trauma treated in the Department of Emergency of Nanjing General Hospital of Nanjing Military Regionfrom February 2015 to November 2015 were retrospecively analysed .GCS ( Glasgow Coma Scale ) score, arterial blood lactate , blood pressureand heart rate were measured once patients admitted to hospital and 6 hours later ,arterial blood lactate was measured again to calculated the arterial blood lac-tate clearance rate .Based on the GCS score , we divided the patients into mild group (13-15), medium group (9-12) and severe group (3-8).We also divided the patients into death group and survival group according toprognosis .We compared arterial blood lactate and lactate clearance rate betweeeneach group respectively . Results There were significant differences in arterial blood lactate (F=19.99,P<0.01) and 6h lactate clearance rate(F=6.21,P<0.01)be-tween lighter group , medium group and severe group .The initial arterial blood lactate of death group was significantly higher than sur-vival group[(4.20 ±1.36)mmol/L vs (1.58 ±0.93)mmol/L], the difference was statistically significant (t=-9.78,P<0.01). The 6 h lactate clearance rate of death group was significantly lower than survival group [(31.73 ±12.84)%vs (46.25 ±12.01)%], the difference was statistically significant (t=4.55,P<0.01). Conclusion Arterial blood lactate and 6 h lactate clearance rate can evaluate the severity and prognosisof illnessin patients with craniocerebral traumaand have important application value in clinical work .

Objective To explore the effects of intestinal trefoil factor ( ITF) on gastric mucosal epithelial cell proliferation and its possible molecular mechanism . Methods The cultured GES-1 cells were treated with ITF in the concentration of 100 ng/mL and 500 ng/mL in vitro, and then were observed using microscope for the morphological analysis .The Cell Counting Kit-8 ( CCK-8) was used to detect the proliferation activity of GES-1.The cultured GES-1 cells were treated with 100 ng/mL ITF and the specific inhibitor of PI3K/Akt signaling pathway LY294002 (15μmol/L) in vitro, and then were observed using microscope for the morphological analysis . The proliferation activity of treated GES-1cells was detected using CCK-8 and the expressions of p-Akt and Akt of PI3K/Akt signaling pathway were determined by Western blot . Results Compared with the control group , the proliferation activity of GES-1 cells in-creased after being treated with ITF and the higher concentration of ITF induced the higher proliferation activity .LY294002 inhibited the increased proliferation activity of GES-1induced by ITF.The data of Western blot indicated that ITF induced the expression of p -Akt and activated the P3IK/Akt signaling pathway to modulate the proliferation activity of GES -1 cells.However, LY294002 inhibited the PI3K/Akt signaling pathway and then decreased the proliferation activity of GES -1 cells. Conclusion ITF could promote the proliferation ac-tivity of GES-1 cells by activating PI3K/Akt signaling pathway .

Objective Though paraquat (PQ) is highly toxic, there is still no effective treatment for PQ poisoning .The aim of the article was to study the protective effect and mechanism of the p 38 mitogen-activated protein kinase ( MAPK) inhibitor SB203580 on PQ-induced acute lung injury in rats . Methods 72 SD rats were randomly divided into three groups ( n=24 ): normal saline (NS) group, PQ poisoning group and p38 inhibitor SB203580 intervention (PQ+SB) group.The arterial blood gas analysis, lung wet and dry ratio (W/D),the expression of tumor necrosis factor-α(TNF-α), the superoxide dismutase (SOD) level and the pathological changes of lung tissues were recorded at different time points after drug intervention . Results On the 1st , 3rd, 5th days after drug intervention in PQ group, the alveolo-arterial oxygen partial pressure difference (PA-aO2) [(45.67 ±4.17), (68.78 ±6.63), (80.23 ±7.12 ) mmHg ], the lung tissue TNF-αexpression (14.63 ±3.10], [18.24 ±2.98], [16.22 ±2.79] pg/mg) and W/D ([4.931 ±0.034], [5.020 ±0.064], [5.079 ±0.016]) in-creased gradually to a peak on the 3rd day, while the SOD level de-creased respectively on the 1st , 3rd, 5th days after drug intervention ([175.26 ±7.98], [167.57 ±8.05], [160.24 ±6.78] U/ug) (P<0.05).Compared with PQ group, PQ+SB group got a decrease in the PA-aO2([80.23 ±7.12] vs [44.17 ±4.16]), the lung tissue TNF-αexpression ([16.22 ±2.79] vs [9.48 ±2.72]) and W/D ([4.805 ±0.070] vs [5.079 ±0.016]) (P<0.05), while the pulmonary SOD level increased in comparison with PQ group ([125.89 ±6.65] vs [160.24 ±6.78]) (P<0.05). Conclusion The p38MAPK inhibitor SB203580 plays a certain protective role in PQ-induced acute lung injury by reducing inflammation and improving antioxidant capacity .

OBJECTIVETo investigate the epidemiological and clinical features of hand, foot and mouth disease (HFMD) since several outbreaks of HFMD caused by enteroviruses were documented in China between 2007 and 2008.

METHODSHFMD cases reported to the National Infectious Disease Information Management System database between May 2008 and April 2009 were assessed. Clinical features in some of the severe and fatal cases were analyzed the etiology of the outbreaks was investigated.

RESULTS89.1% of reported HFMD cases were found in children<5 year-old with an age-specific incidence rate of 834.1/100 000 in the first year as the notifiable disease in China from May 2008 to April 2009. The incidence, mortality and percentage of severe cases were studied for three regions of China and found to be highest in the central region. The incidence of severe cases and mortality in rural population were significantly higher than those in urban population. Among the laboratory confirmed EV17 positive cases there were 52.6% mild, 83.5% severe, and 96.1% fatal cases. More myoclonic jerks were found in the severe case group than in group that died. Tachypnea, lip purpling, pink foaming and low limb temperature occurred more frequently in the fatal cases than in the severe cases.

CONCLUSIONThe epidemic of HFMD in China was characterized predominantly by EV71 infections, had relatively high mortality rates especially in the central region, and was most prevalent in young, rural populations.
