Objective To investigate the clinical values of continuous hemoperfusion on the level of inter-leukin-18(IL-18)and prognosis in patients with acute paraquat poisoning(APP). Methods A total of 112 pa-tients with APP treated in our hospital from Jun 2013 to Jul 2017 were divided into two groups:control group(56 cases,routine drug and single hemoperfusion)and therapy group(56 cases,treated by continuous hemoperfusion based on control group).All APP patients were treated with continuous veno venous hemofiltration(CVVH)at 24 hours after treatment.Within admission 24 hours,3 days and 7 days after treatment,IL-18,lactic acid(Lac),ar-terial oxygen partial pressure(PaO2),alanine aminotransferase(ALT),creatinine(Cr)and creatine kinase(CK-MB)of patients were detected,28-day survival was recorded.Pearson correlation test was used to analyze the corre-lation between IL-18 in patients with APP and the survival rate. Results In admission,there were no differences in the levels of IL-18,Lac,PaO2,ALT,Cr and CK-MB between the two groups(P>0.05).At 3 days after treat-ment,the levels of IL-18,Lac,ALT,Cr and CK-MB were higher than those before treatment,and the therapy group was lower than the control group,while PaO2was lower than those before treatment,and the therapy group was higher than the control group(P<0.05);At 7 days after treatment,the two groups both had lower levels of IL-18,Lac,ALT,Cr and CK-MB than those after 3 days treatment,and the therapy group was lower than the con-trol group,while PaO2was lower than those after 3 days treatment,and the therapy group was higher than the con-trol group(P<0.05);There were 39 deaths in the therapy group and 49 deaths in the control group,the therapy group had a lower 28-day mortality rate than control group,the difference was statistically significant(69.64% vs 87.50%,χ2=5.303,P=0.021). The level of serum IL-18 in patients with APP was negatively correlated with the survival rate(r =-0.209,P = 0.027).Conclusions Therapeutic effect of continuous hemoperfusion in APP pa-tients is superior to single hemoperfusion. It could decrease the levels of IL-18,Lac,ALT,Cr and CK-MB,im-prove PaO2 and reduce the mortality rate of patients.The clinical curative effect is distinct.

Objective:To explore the evaluate of neutrophil gelatinase-associated lipocalin (NGAL) , combined with neutrophil/lymphocyte ratio (NLR) in the early prognosis of patients with acute paraquat poisoning (APP) .Methods:In March 2019, 108 APP patients admitted to Emergency Medicine Department of Hebei Medical University from January 2017 to December 2018 were selected as the observation group, 60 healthy people in the same period were see as the control group according to the results of diagnosis and 28-day survival, the observation group was divided into 51 death group and 57 survival group. The correlation between NGAL, NLR and the death of APP patients was analyzed, to explore the value of NGAL and NLR in predicting the death of APP patients.Results:Compared with the Control group, the NGAL and NLR in the observation group were significantly higher ( P<0.01) , and the NGAL and NLR in the death group were significantly higher ( P<0.05) . The results showed that NGAL and NLR were positively correlated with the death of APP patients on 28th day, and the Correlation Coefficient was 0.456 and 0.638 at 2nd Day ( P<0.01) The area under the ROC curve of NGAL, NLR and their combination were 0.764, 0.869 and 0.905, respectively. Conclusion:The combined detection of NGAL and NLR has important clinical significance in the early prediction of 28-day mortality in APP patients.

Objective:To investigate the effect of transcranial direct current stimulation (tDCS) on cognitive function of delayed encephalopathy after carbon monoxide poisoning (DEACMP) .Methods:A total of 58 patients with DEACMP admitted to the Emergency Medicine Department of Hudson International Peace Hospital from January 2018 to January 2020 were included. According to the random number table, the patients were randomly divided into study group and control group, with 29 patients in each group. Patients in both groups were given nutritional nerve therapy, improved microcirculation, adrenal cortical hormone and other drugs, as well as hyperbaric oxygen and rehabilitation training, once per day. The study group was treated with tDCS (electrode pads were placed and current stimulation was given 30 min/time) 1/d on the basis of conventional treatment, while the control group was treated with tDCS pseudo stimulation (electrode pads were placed and current stimulation was given for 10 s) 1/d for 30 days consecutively. The auditory event-related potential P300 (ERP-P300) was tested before and 30 days after treatment, and the Mini-Mental State Examination (MMSE) scale, Barthel index (BI) and the National Institutes of Health Neurological Impairment score (NIHSS) were used to evaluate and analyze the patients.Results:There was no significant difference in scores between the two groups before treatment (all P>0.05) . After 30 days of treatment, the MMSE score, orientation, memory, attention and computing power, and language ability of the study group were all higher than those of the control group, and the differences were statistically significant ( P<0.05) . 90 days after treatment, the BI of the study group was higher than that of the control group ( P<0.05) . After 30 days of treatment, the NIHSS score of the study group was significantly lower than that of the control group ( P<0.05) . The latency of ERP-P300 in the study group was shorter than that in the control group, and the amplitude was higher than that in the control group at 30 days after treatment, and the difference was statistically significant ( P<0.05) . The latency of ERP-P300 was negatively correlated with the total MMSE score before and after DEACMP treatment ( r=-0.837, -0.819, P<0.05) . The latency of ERP-P300 was negatively correlated with orientation, attention and computing power, and language ability before treatment ( r=-0.698, -0.675, -0.742, P<0.05) . Conclusion:TDCS treatment can help improve the cognitive function of DEACMP patients, and ERP-P300 test can help determine the cognitive function severity of patients.

OBJECTIVE:
To investigate the effect of down-regulation of pannexin 2 (Panx-2) channels on cisplatin-induced apoptosis in I-10 cells.
METHODS:
The expression of Panx-2 protein in testicular cancer cells was detected with Western blotting. The testicular cancer cell line I-10 was transfected with two short hairpin RNA (shRNA1 and shRNA2) Lipofectamine, the empty vector (NC group) or Lipofectamine2000 (blank control group), and the changes in the expression of Panx-2 was detected with Western blotting. The effects of transfection with a Panx-2 inhibitor on surviving fraction of the cells treated with cisplatin (16 μmol/L) for 24 h, 48 h and 72 h was assessed with MTT assay, and the clonogenic capacity of the cells was evaluated with colony-forming assay. At 8 h after incubation with 16 μmol/L cisplatin, AnnexinV/PI double staining was used to detect the early apoptosis of the cells. After 24 h of treatment with 16 μmol/L cisplatin, the cells were examined for expressions of caspase-3, Bcl-2 and Bax using Western blotting.
RESULTS:
The expression of Panx-2 was significantly increased in cisplatin-resistant I-10/DDP ( < 0.001) cells and Tcam-2/DDP ( < 0.01) cells as compared with I-10 cells and Tcam-2 cells. Transfection of I-10 cells with shRNA1 and shRNA2 resulted in significantly decreased Panx-2 expression ( < 0.05) and significantly reduced cell surviving fraction ( < 0.001). In the presence of cisplatin, the cells in NC group showed a higher clonogenic efficiency than those in shRNA1 and shRNA2 groups ( < 0.001). The early-stage apoptosis rate of the cells in shRNA1 and shRNA2 groups were significantly higher than that in NC group ( < 0.01). Panx-2 knockdown in I-10 cells significantly increased caspase-3 and Bax expressions ( < 0.05) and significantly decreased the expression of Bcl-2 ( < 0.01).
CONCLUSIONS
Down-regulation of Panx-2 channel enhances cisplatin-induced apoptosis in cultured testicular cancer cells.
