Objective To investigate the expression levels of Ubiquitin Carboxy-Terminal Hydrolase-L1(UCH-L1)and Netrin-1 in the serum of patients with spontaneous basal ganglia hemorrhage(ICH)complicated with cerebral edema,and to analyze their impacts on neurological deficits and prognosis.Methods A retrospec-tive analysis was conducted on the clinical data of 173 patients with spontaneous basal ganglia hemorrhage admitted to the Department of Neurosurgery,The First Affiliated Hospital of Bengbu Medical University from September 2023 to January 2025.The serum levels of UCH-L1 and Netrin-1 were measured within 24 hours after the onset.They were divided into three groups according to the size of the cerebral edema volume(CEV):Group A(CEV<10 mL),Group B(CEV 10～30 mL),and Group C(CEV>30 mL).Pearson's correlation analysis was used to analyze the correlation between serum expression levels of UCH-L1 and Netrin-1 with hemorrhage,volume of cere-bral edema,distance of midline shift,Modified Edinburgh-Scandinavian Stroke Scale(MESSS)score,Modified Rankin Scale(mRS)score,and Glasgow Coma Scale(GCS)score.Logistic regression analysis was performed to identify the risk factors for poor prognosis.Receiver operating characteristic(ROC)curve analysis was used to evaluate the predictive value of UCH-L1 and netrin-1 for poor prognosis.Results Significant differences were observed in the serum levels of UCH-L1 and netrin-1 among patients with different volumes of cerebral edema(P<0.05).The larger the volume of cerebral edema,the higher the expression levels of UCH-L1 and netrin-1.The serum levels of UCH-L1 and Netrin-1 were significantly higher in the poor prognosis group compared to the good prognosis group(P<0.05).The serum levels of UCH-L1 and Netrin-1 were positively correlated with MESSS score,hemorrhage volume,cerebral edema volume,distance of midline shift,and mRS score(P<0.05),and negatively correlated with GCS score(P<0.05).Multivariate Logistic regression analysis showed that both UCH-L1 and netrin-1 were independent risk factors for poor neurological prognosis in basal ganglia hemorrhage patients(P<0.05).ROC curve analysis indicated that both markers had important predictive value for poor prognosis.The AUC for serum UCH-L1 level predicting poor prognosis was 0.77[95%confidence interval(CI):0.69～0.85,P<0.01],with a sensitivity of 84.9%and a specificity of 50.6%.The AUC for serum Netrin-1 level predicting poor prognosis was 0.89(95%CI:0.85～0.94,P<0.01),with a sensitivity of 82.1%and a specificity of 68.7%.Conclusions Serum UCH-L1 and Netrin-1 are differentially expressed in patients with spontaneous basal ganglia hemorrhage complicated with different volumes of cerebral edema.They are independent risk factors for poor prog-nosis and are important predictors of neurological function prognosis in these patients.

Objective:To analyze the trend of liver cancer morbidity and mortality among residents with household registration in certain District, 2017 to 2019.Methods:The crude morbidity and mortality rate of males and females in the whole population were calculated by using the relevant data from the certain District Cancer Registry and Report System and the Cause of Death Surveillance System. The standardized morbidity and mortality rate were calculated according to the age structure of 2000 National Demographic Census and Segi's world population, respectively. Trend in liver cancer morbidity and mortality were evaluated using percent change (PC), annual percentage change, and case-number-weighted annual percent change. Age-specific rates were used to analyze the epidemic trend of liver cancer with age.Results:The crude morbidity rate of liver cancer in the whole population (male and female) of the certain district from 2017 to 2019 were 18.86/100 000, 26.05/100 000 and 11.90/100 000 respectively, and the crude mortality rates were 21.20/100 000, 29.29/100 000 and 13.38/100 000 respectively. The crude morbidity and mortality rate of liver cancer among male showed a downward trend (PC=-16.77% and -20.15% respectively). The crude morbidity and mortality rate of liver cancer among female showed inconsistent changes; however, the crude morbidity rate showed a downward trend, and the crude mortality rate first increased and then decreased (PC=-19.42% and -0.30% respectively). Liver cancer morbidity and mortality rate in male after the age of 30 were increased with age. The two key points of accelerated growth were around the age of 65 and 75, and the peak of morbidity (130.78/100 000) and mortality (201.96/100 000) were after the age of 80. The morbidity and mortality rate were significantly lower in female than those of male aged 60; however, after the age of 65, the morbidity rate was increased rapidly and gradually approached as that of male. After the age of 80 (the peak morbidity and mortality were 104.40/100,000 and 132.87/100,000, respectively), male were about twice as high as those female aged between 75 and 79.Conclusion:Morbidity and mortality rate of liver cancer in the certain District showed an overall downward trend from 2017 to 2019, but it increased with age, and the disease burden was relatively high among the elderly population. Liver cancer mostly occurred in male, so the prevention and control of liver cancer epidemics in middle-aged and elderly should be actively monitored.

Objective To investigate the target blood pressure level of restrictive fluid resuscitation in patients with traumatic hemorrhagic shock. Methods Sixty patients with traumatic hemorrhagic shock admitted to the First Affiliated Hospital of Bengbu Medical College from January 2016 to December 2018 were enrolled. All patients were resuscitated with sodium acetate ringer solution after admission. According to the difference of mean arterial pressure (MAP) target, the patients were divided into low MAP (60 mmHg ≤ MAP < 65 mmHg, 1 mmHg = 0.133 kPa), middle MAP (65 mmHg ≤ MAP < 70 mmHg) and high MAP (70 mmHg ≤ MAP < 75 mmHg) groups by random number table using the admission order with 20 patients in each group. Those who failed to reach the target MAP after 30-minute resuscitation were excluded and supplementary cases were deferred. The restrictive fluid resuscitation phase was divided into three phases: before fluid resuscitation, liquid resuscitation for 30 minutes and 60 minutes. The most suitable resuscitation blood pressure level was further speculated by monitoring the inflammatory markers and hemodynamics in different periods in each group of patients. Pearson correlation analysis was used to detect the correlation of variables. Results Before fluid resuscitation, there was no significant difference in hemodynamics or expressions of serum cytokines among the three groups. Three groups of patients were resuscitated for 30 minutes to achieve the target blood pressure level and maintain 30 minutes. With the prolongation of fluid resuscitation time, the central venous pressure (CVP), cardiac output (CO) and cardiac index (CI) were increased slowly in the three groups, and reached a steady state at about 30 minutes after resuscitation, especially in the high MAP group and the middle MAP group. The expressions of serum inflammatory factors in the three groups were gradually increased with the prolongation of fluid resuscitation time. Compared with the low MAP group and the high MAP group, after 30 minutes of resuscitation the middle MAP group was superior to the other two groups in inhibiting the expressions of pro-inflammatory factors tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6) and promoting anti-inflammatory factors IL-10 [TNF-α mRNA (2-ΔΔCt):0.21±0.13 vs. 0.69±0.34, 0.57±0.35; IL-6 mRNA (2-ΔΔCt): 0.35±0.31 vs. 0.72±0.39, 0.59±0.42; IL-10 mRNA (2-ΔΔCt): 1.25±0.81 vs. 0.61±0.46, 0.82±0.53; all P < 0.05], but there was no significant difference in promoting the expression of IL-4 mRNA among three groups. At 60 minutes of resuscitation, compared with the low MAP group and the high MAP group, the middle MAP group could significantly inhibit the expressions of TNF-α, IL-6 and promote IL-10 [TNF-α mRNA (2-ΔΔCt): 0.72±0.35 vs. 1.05±0.54, 1.03±0.49; IL-6 mRNA (2-ΔΔCt): 0.57±0.50 vs. 1.27±0.72, 1.01±0.64; IL-10 mRNA (2-ΔΔCt): 1.41±0.90 vs. 0.81±0.48, 0.94±0.61; all P < 0.05]. Compared with the high MAP group, the middle MAP group had significant differences in promoting the expression of IL-4 mRNA (2-ΔΔCt: 1.32±0.62 vs. 0.91±0.60, P < 0.05). There was no significant difference in serum cytokine expressions at different time points of resuscitation between the low MAP group and the high MAP group (all P > 0.05). Correlation analysis showed that there was a strong linear correlation between MAP and mRNA expressions of TNF-α, IL-6, IL-10 in the middle MAP group (r value was 0.766, 0.719, 0.692, respectively, all P < 0.01), but had no correlation with IL-4 (r = 0.361, P = 0.059). Fitting linear regression analysis showed an increase in 1 mmHg per MAP, the expression of TNF-α mRNA increased by 0.027 [95% confidence interval (95%CI) = 0.023-0.031, P < 0.001], IL-6 mRNA increased by 0.021 (95%CI = 0.017-0.024, P < 0.001), and IL-10 mRNA increased by 0.049 (95%CI = 0.041-0.058, P < 0.001). Conclusions When patients with traumatic hemorrhagic shock received restrict fluid resuscitation at MAP of 65-70 mmHg, the effect of reducing systemic inflammatory response and improving hemodynamics is better than the target MAP at 60-65 mmHg or 70-75 mmHg. It is suggested that 65-70 mmHg may be an ideal target MAP level for restrictive fluid resuscitation.

Objective To analyze the clinical values of super early enteral nutrition combined with microecopharmaceutics and delayed enteral nutrition on patients with severe acute pancreatitis. Methods Clinical data of thirty patients diagnosed as severe acute pancreatitis in our emergency department during January 2013 and December 2017 were reviewed retrospectively. Patients were divided into the treatment group (n=15, patients given enteral nutrition combined with microecopharmaceutics within 24 h after admission) and the control group (n=15, patients given delayed enteral nutrition after 48 h of admission). Two weeks after the treatment, the serum variables of C-reactive protein, total protein, albumin, recovery time of urine and blood amylase, length of hospital stay and APACHE Ⅱ score were compared between the two groups by using paired samples t test. Results The C-reactive protein [(46.7±13.1) mg/L vs. (190.72±19.3) mg/L, t=10.4, P<0.01] and APACHE Ⅱ score [(7.2±1.9) vs.(9.3±2.4),t=2.7,P<0.05] of the treatment group were significantly lower than those in the control group. The total protein [(58.1±6.3)g/L vs.(52.6±5.4)g/L, t=2.5, P<0.05] and albumin [(29.9±3.2)g/L vs.(22.0±2.8)g/L, t=7.12, P<0.01] of the treatment group were significantly higher than those in the control group. The recovery time of urine amylase [(13.2±2.1)d vs.(18.7±3.9)d, t=4.9, P<0.01] and blood amylase [(7.5±3.0)d vs.(11.1±3.4)d, t=3.1, P<0.01], and length of hospital stay[(14.9±4.5)d vs.(27.1±5.3)d, t=6.9, P<0.01] were significantly shorter in the treatment group compared with those in the control group. Conclusions Ultra-early enteral nutrition combined with microecopharmaceutics can shorten the length of hospital stay of patients with severe acute pancreatitis, and is safe and effective.

BACKGROUND: There are so many experimental and clinical researches on levels of nitrogen monoxide (NO) in serum and endothelins in plasma of patients with stroke; however, ratio and significance between them are still unclear.OBJECTIVE: To observe dynamic changes of levels of NO in serum and endothelins in plasma of patients with stroke.DESIGN: Case-controlled observation.SETTING: Neurological Department and Clinical Neurological Laboratory of the Second Hospital affiliated to Suzhou University.PARTICIPANTS: A total of 216 patients with acute cerebral infarction including 133 males and 83 females and 112 cases with cerebral hemorrhage including 68 males and 44 females were selected from Neurological Department of the Second Hospital affiliated to Suzhou University from September 1999 to December 2001. Another 106 subjects including 63males and 43 females were regarded as healthy control group.METHODS: Contents of NO in serum and endothelins in plasma were measured on 328 patients with stroke and 106 healthy subjects in the courses of 1-3 days, 1, 2, 4, 8 and 12 weeks with nitrate reductase and radio-immunity methods, respectively.MAIN OUTCOME MEASURES: Contents of NO in serum and endothelins in plasma; ratio between NO in serum and endothelins in plasma (NO/endothelins).RESULTS: ① As compared with those in the control group, content of NO in serum of patients with cerebral infarction and cerebral hemorrhage was decreased and reached the lowest value during acute period (within 1-3 days), and then increased gradually and closed to the normal level at about 4 weeks. In addition, content of endothelins in plasma was increased obviously during acute period, reached the peak at 2 weeks, and then decreased gradually. The level was still high at stage of recovery and closed to normal value within 4-8 weeks. ② As compared with that in the control group, NO/endothelins was decreased in cerebral infarction group at the courses of 1-3 days (P ＜ 0.05), reached the lowest value at 1 week (P ＜ 0.001), and increased to the normal level at 2 weeks. Moreover,NO/endothelins was remarkably decreased in cerebral hemorrhage group at the courses of 1-3 days (P ＜ 0.001), reached the lowest value at 1week (P ＜ 0.001), and increased gradually. The changes of course were great and the level reached above normal value at 8 weeks. There was significant difference of dynamic changes of NO/endothelins between cerebral hemorrhage group and cerebral infarction group (P ＜ 0.05).CONCLUSION: NO and endothelins play an important role in onset and development of ischemic cerebrovascular disease and hemorrhagic cerebrovascular disease, and their contents are related to prognosis.
