Objective:To investigate the clinical significance of soluble growth stimulating expression gene 2 protein (sST2) combined with neutrophil/lymphocyte ratio (NLR) in the prediction of nosocomial cardiovascular adverse events in patients with acute carbon monoxide poisoning (ACOP) myocardial injury.Methods:Patients with ACOP myocardial injury from January 2017 to December 2019 in Emergency Ward and EICU of Harrson International Peace Hospital, Hebei Medical University were enrolled. NLR was calculated by routine blood examination on admission, and sST2 (T 0sST2, T 3dsST2) was detected by ELISA on admission and at 3 days after admission. According to the occurrence of cardiovascular adverse events, the patients were divided into the event group and the non-event group. Logistic regression was used to analyze the risk factors of in-hospital cardiovascular adverse events. ROC curve was used to analyze the value of sST2, NLR, sST2 and NLR combined in predicting the occurrence of in-hospital cardiovascular adverse events in patients with ACOP myocardial injury. Results:Totally 255 patients with ACOP myocardial injury were included in the final analysis. NLR was (13.38±4.33) in the event group and (9.57±4.22) in the non-event group, T 3dsST2 was (61.59±22.67) ng/mL in the event group and (40.52±13.14) ng/mL in the non-event group, with statistically significant differences (all P<0.01). T 0sST2 was (265.34±89.95) ng/mL in the event group and (242.43±93.09) ng/mL in the non-event group, with no statistically significant difference ( P=0.333). Logistic regression analysis showed that NLR ( OR=1.270, 95% CI: 1.125-1.434, P<0.01) and T 3dsST2 ( OR=1.082, 95% CI: 1.052-1.114, P<0.01) were independent risk factors for nosocomial cardiovascular adverse events in patients with ACOP myocardial injury. The optimal cutoff value of T 3dsST2 was 44.5 ng/mL, and of NLR was 12.08. The sensitivity and specificity of dual T 3dsST2 and NLR in predicting nosocomial cardiovascular adverse events was 79.3% and 82.7%, respectively (AUC 0.857, Youden index 0.620). Conclusions:T 3dsST2 and NLR are independent risk factors for the nosocomial cardiovascular adverse events in patients with ACOP myocardial injury. The predictive cutoff values are 44.5 ng/mL for T 3dsST2 and 12.08 for NLR. Combination of T 3dsST2 and NLR has a practical predictive value for nosocomial cardiovascular adverse events in patients with ACOP myocardial injury.

Objective To study the value of copeptin and APACHE Ⅱ used for assessing acute paraquat poisoning (APP). Methods One hundred and twenty six APP patients were divided into survival group (n = 58) and death group (n = 68), with clinical death as the endpoint of observation. 3 mL blood was obtained from each subject at 2 h , 24 h and 7 d after admission for detecting the levels of copeptin , and APACHE Ⅱ scores were recorded at the same time. Results There was significant difference in dosages of paraquat taken in the death group and the survival group , but the differences were significant in the rescue time , the first time for hemoperfusion and the times for hemoperfusion. 2 h after admission , the death group and survival group had significant difference in elevated copeptin but no significant difference in scores by APACHE Ⅱ. 24 h after admission copeptin decreased to normal level in the survival group but maintained at a higher level in the death group, while the scores by APACHE Ⅱ had insignificant difference between two groups. 7 d after admission, copeptin kept at a higher level and the scores by APACHE Ⅱwere significantly increased in the death group , with significant differences compared to the survival group. The oral doses of pesticides the patients took were positively correlated with copeptin level and scores by APACHE Ⅱ. Conclusion Repeated detection of copeptin and APACHE Ⅱ score are of clinical importance for the assessment of prognosis of APP patients and reasonable distribution of medical resources.

Objective:To analyze the clinical and pathological features of asymptomatic primary hyperparathyroidism (PHPT) .Methods:A retrospective analysis was carried out in terms of the clinical characteristics and pathological data in 30 patients with asymptomatic PHPT and 86 patients with typical PHPT hospitalized in the Department of Endocrinology and General Surgery of Beijing Jishuitan Hospital from Jan. 2013 to Dec. 2018. There were 7 males (23.3%) and 23 females (76.7%) , with a male to female ratio of 1:3.3. The average age was 56.9±13.3 years. In typical PHPT group, there were 32 males (37.2%) and 54 females (62.8%) , with the average age of 46.4±17.0 years. Bone metabolism indicators included bone density and bone biochemical markers (parathyroid hormone, 25-hydroxyvitamin D and alkaline phosphatase) . The t test was used to compare normally distributed variables, the Mann-Whitney rank sum test was used to compare skewed distributed variables, and the χ 2 test was used to compare enumeration data. Results:The median serum parathyroid hormone and alkaline phosphatase were 144.2 (108.1, 207.0) pg/ml and 80.0 (53.7, 105.5) IU/L respectively, the average serum concentration of calcium was 2.80±0.20 mmol/L, which were significantly lower than those of the classic group ( P<0.05) . The median serum 25-hydroxyvitamin D was 12.14 (7.87, 14.38) ng/ml, which was higher than that of the classic group ( P<0.001) . Ten patients (33.3%) developed osteoporosis, and the incidence was lower than that of the classic group ( P< 0.001) . The median tumor weight was 0.80 (0.25, 1.98) g, significantly smaller than that in the classical group ( P=0.003) . There were 26 cases (86.7%, including 2 atypical parathyroid adenomas) of parathyroid adenomas and 4 cases (13.3%) of hyperplasia. Conclusions:The asymptomatic PHPT has the same sex ratio as the classic type, mainly female, but the average age is significantly higher than that in the classic type. Although asymptomatic PHPT in this study are all benign lesions, abnormal bone biochemical indicators, especially vitamin D deficiency, are common, which also lead to osteoporosis.

Porcine reproductive and respiratory syndrome virus (PRRSV) non-structural protein 7 (Nsp7) plays an important role in the induction of host humoral immune response and could serve as an ideal antigen for serological genotyping assay for PRRSV based on the significant difference in immunoreactivities of North American (NA) and European (EU) PRRSV Nsp7. In this study, Nsp7 of NA and EU PRRSVwas separately expressed and purified using prokaryotic expression system. The purified recombinant Nsp7 proteins reacted with serum antibodies against corresponding genotype PRRSV in Western blotting. However, nonspecific reaction of whole recombinant Nsp7 with antibodies against another genotype PRRSV was observed, indicating that whole NA PRRSV Nsp7 and EU PRRSV Nsp7 have similar antigenic epitopes and recombinant proteins could not be used for genotyping of antibodies against PRRSV. Based on the analysis of similar antigenic epitopes at the hydrophilic region of NA PRRSV Nsp7 and EU PRRSV Nsp7 by bioinformatics assessment, partial Nsp7 gene region deleted sequences encoding similar antigenic epitopes was constructed by fusion PCR. The recombinant truncated Nsp7 (NA-deltaNsp7 and EU-deltaNsp7, about 43 kDa) was expressed and the molecular weight was about 43 kDa. The results of Western blotting showed that NA-deltaNSP7 and EU-deltaNSP7 could be specifically recognized by positive serum to NA or EU PRRSV individually and nonspecific reaction was eliminated. This study provided a basis for further development of serological genotyping assay for North American and European genotype PRRSV infection.
