Objective To study the clinical characteristics and long term prognosis of the neonates with hypoxic ischemic encephalopathy (HIE) and explore therapy to improve the prognosis. Methods Data of 1150 newborns with HIE were analyzed. retrospectively. Results There were 942 full term babies(81.9%) and 208 prematures(18.1%). Most of them were caused by anoxia occurring in intrauterine period or at birth, 75.0% of them with superimposed intracranial hemorrhage. The mortality rate was 7.0%(32.8% severe HIE, 4.2% moderate HIE). Among 852 surviors with follow up, the sequenlae rate is 10%(60.7% in severe HIE,4.5% in moderate HIE). The prognosis were bad. The therapy to improve the prognoses are as follow:(1)Early diagnosis and clinical intervention.(2)To maintein the hemostasis is the major principle of treatment.(3)To prevent organ function damage.(4)Long term(4 to 6 months) of Hyperbaric oxygen therapy should be applied to newborns with severe HIE.(5)Early follow up from newborn period and preventive intervention. Conclusion Prognoses of both newborn with sever HIE and prematures are bad. Long term treatment after newborn period is necessary to improve the prognosis.

Objective:To explore the risk factors of acute respiratory distress syndrome (ARDS) secondary to severe multiple trauma and the role of clinical guidance.Methods:The clinical data of 115 patients with severe multiple trauma admitted to the trauma center of Zhenjiang First People's Hospital from December 2017 to September 2020 were retrospectively analyzed. According to whether ARDS occurred within 1 week of the disease course, the patients were divided into ARDS group and non-ARDS group. The basic post-traumatic data, initial treatment measures (within 24 hours), pathophysiology, stress metabolism, and post-traumatic complications of the two groups of patients were selected for univariate analysis, the statistically different indicators of univariate analysis were incorporated into the multivariate Logistic regression analysis to screen out independent high-risk factors that affect the occurrence of ARDS in patients with severe multiple trauma, and a receiver operating characteristic curve (ROC curve) was drawn to analyze the effects of each risk factor on the occurrence of ARDS.Results:Among 115 patients, there were 45 casesin the ARDS group and 70 cases in the non-ARDS group. Compared with the non-ARDS group, the patients in the ARDS group were older (years: 57.45±15.37 vs. 45.68±12.70), and the proportion of patients combined with moderate-severe chest trauma, traumatic brain injury (TBI), shock, and massive blood transfusion were higher (71.11% vs. 31.43%, 44.44% vs. 28.57%, 80.00% vs. 67.14%, 46.67% vs. 27.14%). In the ARDS group, procalcitonin [PCT (μg/L):29.73±6.08 vs. 12.45±2.12], thrombomodulin [TM (ng/L): 83.43±16.34 vs. 37.66±14.64], blood glucose (mmol/L:17.2±5.0 vs. 10.3±2.4), triacylglycerol [TG (mmol/L): 3.77±0.57 vs. 2.22±0.63], interleukin-6 [IL-6 (ng/L):38.97±10.79 vs. 25.98±5.40], tumor necrosis factor-α [TNF-α (ng/L): 48.78±13.99 vs. 35.30±13.03], intra-abdominal pressure [mmHg (1 mmHg = 0.133 kPa): 25.21±3.59 vs. 11.98±4.91], serum creatinine [SCr (μmol/L):180.45±42.35 vs. 132.17±49.36] and blood urea nitrogen [BUN (mmol/L): 13.83±4.97 vs. 8.80±4.32] were significantly higher than those in the non-ARDS group; the proportion of patients with crystal infusion volume ≥ 3 000 mL(26.67% vs. 34.29%) and platelet count [PLT (×10 9/L): 72.67±7.96 vs. 127.99±17.65] and the levels of plasma glutathione peroxidase [GSH-Px (kU/L): 87.15±27.81 vs. 161.15±17.94], plasma superoxide dismutase [SOD (kU/L):92.65±32.67 vs. 125.58±38.96] were significantly lower than those in the non-ARDS group, the differences were statistically significant (all P < 0.05). Multivariate Logistic regression analysis showed that 11 indicators such as age, combined moderate-severe chest trauma, combined TBI, massive blood transfusion, PCT, TM, blood glucose, TNF-α, plasma GSH-Px, intra-abdominal pressure and SCr were independent risk factors that could predict ARDS secondary to severe multiple trauma, the odds ratio ( OR) and 95% confidence interval (95% CI) were 1.201 (1.035-1.165), 3.414 (1.217-8.876), 2.889 (1.124-8.109), 3.134 (1.322-9.261), 1.467 (1.096-2.307), 2.428 (0.024-0.973), 5.787 (1.246-9.642), 1.106 (0.949-5.108), 7.450 (1.587-10.261), 3.144 (1.217-8.876), 1.051 (1.002-1.542) respectively, the P valueswere 0.008, 0.024, 0.044, 0.017, 0.018, 0.045, 0.026, 0.037, 0.005, 0.029, 0.033 respectively. ROC curve analysis showed that plasma GSH-Px had a higher predictive value for ARDS secondary to severe multiple trauma, the area underROC curve (AUC) = 0.873, 95% CI was 0.798-0.928, P = 0.000, when the best cut-off value at 72.22 kU/L, its sensitivitywas 86.7%, specificity was 75.7%, positive predictive value was 69.6%, and negative predictive value was 89.8%. The Logistic regression model established by 11 independent high-risk factors had an accuracy rate of 81.74% in predicting ARDS secondary to severe multiple trauma, which had a good guiding significance for predicting ARDS. Conclusion:Our study showed that there are many risk factors for ARDS secondary to severe multiple trauma, involvingbasic post-traumatic data, initial treatment measures, pathophysiology, stress metabolism, post-traumatic complications, etc. Early identification and intervention may be beneficial to improve the success rate of treatment for such patients.

AIM To evaluate the effect of METHODS 2 month-old mice were fed routinelycistanche desertica polysacchrides(CDP) on the ni- for 11 mounths to establish the model of naturallytric oxids(NO) ,superoxide dismutase(SOD) in se- aging mice. The cistanche desertica polysacchridesrum and apoptosis of lung cell in aging mice. 25, 50, 100 mg ?kg~' were administrated respec- lively to the mice po. then investigated the concentration of NO, SOD and the morphological changes of apoptosis by fluoromicroscope. RESULTS Aging could induce the lung cell apoptosis, decrease the level of SOD, and increase the level of NO as well. The cistanche desertica polysacchrides signif- icantly ameliorated the lung cell apoptosis; decreased the level of NO, improved the activity of SOD. CONCLUSION Cistanche desertica polysac-chrides have ameliorating and postponing effects on the regressive changes in the lung of aging mice.

Objective To investigate the diagnostic efficacy and clinical value of GNB4 and Riplet gene methylation alone and in combination in the diagnosis of primary liver cancer.Methods A total of 313 patients were selected,including 78 patients with primary liver cancer,41 patients with other digestive system tumors,17 patients with non-digestive system tumors,20 patients with postoperative liver cancer,and 157 patients with benign liver disea-ses.The levels of GNB4 and Riplet gene methylation in plasma were detected using quantitative methylation-specific PCR(qMSP).Serum alpha-fetoprotein(AFP)levels were measured by direct chemiluminescence.Results The sensitivity and specificity of AFP in diagnosis were 51.3％and 94.3％,respectively;the sensitivity and specificity of GNB4 gene methylation in diagnosis were 83.3％and 99.4％,respectively;the sensitivity and specificity of Riplet gene methylation in diagnosis were 73.1％and 99.4％,respectively.The sensitivity and specificity of GNB4 and Riplet gene methylation combined diagnosis were 92.3％and 98.7％,respectively;the sensitivity and specificity of AFP,GNB4 and Riplet gene methylation combined diagnosis were 92.3％and 98.7％,respectively;the sensitivity and specificity of combined diagnosis including age and gender were 93.6％and 97.5％,respective-ly.Conclusion The sensitivity and specificity of AFP in the diagnosis of primary liver cancer are limited,while the methylation levels of GNB4 and Riplet genes are higher,and the sensitivity and specificity of their combined de-tection are higher than those of AFP.The sensitivity and specificity of AFP,GNB4 and Riplet gene methylation combined diagnosis are significantly higher than those of AFP,GNB4 and Riplet gene methylation alone.
