Objective To comprehensively evaluate the clinical efficacy of hemoperfusion (HP) combined with continuous veno-venous hemofiltration (CVVH) on acute paraquat poisoning (APP).Methods Literatures of Chinese and English randomized controlled trials (RCTs), case control and cohort study on HP combined with CVVH in the treatment of APP from the PubMed, Embase, Wanfang, and CNKI up to November 2017 were enrolled (the subjects were > 16 years old). The obtained literatures were strictly screened and evaluated in quality, and data such as mortality, the life time of dead patients, inefficiency rate, incidence of multiple organ dysfunction syndrome (MODS) and acute respiratory distress syndrome (ARDS) were extracted. Meta-analysis was performed by RevMan 5.3. Results Twenty-one studies were included with 2222 subjects, among whom 976 subjects were in HP combined with CVVH group (experimental group) and 1246 subjects in HP group (control group). Compared with control group, the mortality in experimental group were significantly decreased [43.77% (362/827) vs. 55.26% (604/1093), odds ratio (OR) =0.68, 95% confidential interval (95%CI) = 0.56-0.82,P = 0.0001], the life time of death patients was significantly prolonged [mean difference (MD) = 4.63, 95%CI = 2.60-6.66,P < 0.00001], incidence of MODS [25.93% (70/270) vs. 55.36% (155/280),OR = 0.26, 95%CI = 0.14-0.49,P< 0.0001], and incidence of ARDS [30.37% (82/270) vs. 51.07%(143/280),OR = 0.42, 95%CI = 0.30-0.61,P < 0.00001], and inefficiency rate [8.72% (13/149) vs. 34.64% (53/153),OR=0.17, 95%CI = 0.09-0.34, P < 0.00001] were significantly reduced. Funnel chart showed that except the publication bias of mortality rate, there were less publication bias about other indicators among studies.Conclusion HP combined with CVVH can significantly reduce the mortality of patients with APP compared with HP alone on the whole, prolong the life time and reduce the occurrence of MODS and ARDS, thus improving the treatment efficiency.

Objective To investigate the predictive value of extra pulmonary multiple factors including creatine kinase-isoenzyme MB (CK-MB) for the prognosis of patients with acute paraquat poisoning.Methods A retrospectively analysis were conducted on 641 patients who were treated at the First Affiliated Hospital of Zhengzhou University due to oral paraquat poisoning from October 2002 to April 2017.The observation end point was that the patients died from paraquat poisoning within 3 months after admission or were still alive within 3 months after paraquat poisoning.The patients' data were retrieved,including general information,the dose of poison,urinary paraquat concentration,arterial blood gas analysis,alanine transaminase (ALT),total bilirubin (TBIL),uric acid (UA),aspartate transaminase (AST),creatine kinase (CK),CK-MB,B type natriuretic peptide (BNP),lactic dehydrogenase (LDH),high sensitivity troponin T (hsTnT),C-reaction protein (CRP) and procaicitonin (PCT).According to the patient's prognosis within 3 months,the patients were divided into a survival group and a non-survival group.The above indicators were compared between the two groups and the diagnostic value of CK-MB for acute paraquat poisoning was analyzed according to the receiver operating characteristics (ROC) curve.Collect the last arterial blood gas analysis,and laboratory test results were analyzed by binary logistic regression analysis to determine the risk factors for death in patients with acute paraquat poisoning.Results Among the 641 patients with acute paraquat poisoning,315 (49.1%) patients survived and 326 (50.9%) died.Compared with the survival group,patients in the non-survival groupthere were older,had a shorter hospital stay,and had a higher oral paraquat dose and urinary paraquat concentration;Lac,TBIL,UA,AST,CK,CK-MB,BNP,LDH,CRP and PCT were higher,while blood gas analysis index were lower in the non-survival group (P<0.05).Binary logistic regression analysis showed that the dose of paraquat,CK-MB and AST were closely related to the prognosis of patients with acute paraquat poisoning.The optimal cut-off value of ingestion dose,the first urinary paraquat concentration on admission and CK-MB in predicting the prognosis of patients with acute paraquat poisoning were 7 g (AUC=0.918,sensitivity 80.6%,specificity 87.5%,Yoden index 0.681,P<0.01),5.16 μg/mL (AUC=0.879,sensitivity 93.8%,specificity 70.1%,Yoden index 0.639,P<0.01),and 18.2 U/L (AUC=0.846,sensitivity 83.9%,specificity 71.9%,Yoden index 0.558,P<0.01),respectively.Binary logistic regression analysis of the last biochemical indicators of paraquat poisoning showed that the dose of poison,the last CK-MB,the last SCr,urinary paraquat concentration,and the last blood Na+ were closely related to the prognosis of patients with acute paraquat poisoning.Among them,the last CK-MB>18.05 U/L often indicated poor prognosis (AUC=0.808,sensitivity 79.7%,specificity 65.8%,Yoden index 0.455,P<0.01).Conclusions In the treatment of patients with acute paraquat poisoning,there are significant differences in extra pulmonary factors such as heart,liver,kidney,electrolytes and inflammatory markers in patients with different prognosis,so the monitoring and follow-up should be improved,in addition to focusing on the presence and treatment of pulmonary fibrosis.In particular,CK-MB is an independent risk factor for the prognosis of acute paraquat poisoning.In the late stage of poisoning,CK-MB,SCr,and blood Na+ have a strong predictive value for the prognosis of the patients,and we should pay attention to the regular follow-up of the above mentioned laboratory items.

In order to prevent the canceration of gallbladder polyps or avoid the misdiagnosis of gallbladder cancer,the mainstream practice is cholecystectomy for polyps larger than 1 cm,while gallbladder polyps larger than 0.5 cm as an indication of gallbladder preserving surgery.The reasons for this result is that we put the diameter of more than 1 cm of gallbladder polyps as high risk factors for prediction of gallbladder carcinoma,and we ignored the characteristics of gallbladder polyps that most of them are not gallbladder cancer or are not cancerous even larger than 1 cm.We analysed the high risk factors for gallbladder cancer on the basis of variety of clinical data,and we believe that the most valuable indicator of gallbladder cancer are the growth time of gallbladder polyps,the age of the patients,the combination of gallstones,the single polyps,and the sex.Polyps diameter greater than 1 cm are not a high risk factor for gallbladder cancer.We can use these five high risk factors to manage gallbladder polyps and reduce unnecessary cholecystectomy and gallbladder preserving surgery.

OBJECTIVE:
To investigate the clinical characteristics and risk factors of acute leukemia complicated with multi-drug resistant bacterial septicemia in children.
METHODS:
The clinical data of children with acute leukemia complicated with septicemia admitted to the Affiliated Hospital of Guangdong Medical University from January 2013 to May 2021 were retrospectively analyzed. Their flora composition and drug resistance were also analyzed. The children were divided into multi-drug resistant bacteria (MDRB) group and non-multi-drug resistant bacteria (non-MDRB) group according to the drug sensitivity results, and the differences in clinical data between the two group were compared.
RESULTS:
A total of 108 children had drug sensitivity results, 47 cases in the MDRB group, including 26 strians of Gram-positive bacteria (G+), the most common multi-drug resistant G+ bacteria were coagulase-negative staphylococci (CoNS) and Staphylococcus aureus, and the most common multi-drug resistant Gram-negative bacteria G- bacteria were Escherichia coli and Klebsiella pneumoniae subspecies pneumoniae. Compared with non-MDRB group, children in MDRB group had higher C-reactive protein (CRP) level and mortality rate (P <0.001, P =0.009), lower initial empirical anti-infection efficiency (P <0.001), and were more likely to have septic shock (P =0.003). Logistic analysis showed that the risk factors of acute leukemia complicated with MDRB septicemia in children were previous MDRB infection (OR =6.763, 95% CI: 1.141-40.092, P =0.035), duration of agranulocytosis before infection≥7 days (OR =3.071, 95% CI: 1.139-8.282, P =0.027), and previous use of antimicrobial drugs within 90 days before infection (OR =7.675, 95% CI: 1.581-37.261, P =0.011).
CONCLUSIONS
The clinical features of acute leukemia complicated with MDRB septicemia in children include a heavy inflammatory response, significantly elevated CRP, susceptibility to secondary septic shock, low efficiency of initial empirical anti-infective therapy, and high mortality rate. Previous MDRB infection, duration of agranulocytosis before infection≥7 days, and previous use of antimicrobial drugs within 90 days before infection are risk factors of acute leukemia complicated with MDRB septicemia in children.
