Objective:To explore the efficacy and safety of sivelestat sodium in patients with acute respiratory distress syndrome (ARDS) in the intensive care unit (ICU).Methods:Sixty patients with ARDS admitted to the ICU of the Fuyang Hospital Affiliated to Anhui Medical University from August 1, 2023 to November 1, 2024 were selected and divided into the control group (conventional treatment, 30 cases) and the sivelestat sodium group (treated with sivelestat sodium in addition to conventional treatment, 30 cases) by the random number table method. The clinical data such as inflammatory factors, blood gas analysis indicators, Acute Physiology and Chronic Health Evaluation (APACHE) Ⅱ score and Sequential Organ Failure Assessment (SOFA) score of the two groups of patients before treatment and 3 days after treatment were compared. The prognostic indicators such as mechanical ventilation time, ICU stay time, total hospital stay time, 28-day mortality rate and clinical efficacy of the two groups of patients were compared.Results:Before treatment, there were no statistically significant differences in inflammatory factors, blood gas analysis indicators, APACHE Ⅱ score and SOFA score between the two groups of patients (all P>0.05). After 3 days of treatment, the improvement degrees of APACHE Ⅱ score, SOFA score, arterial partial pressure of oxygen (PaO 2), oxygenation index (PaO 2/FiO 2), procalcitonin (PCT), interleukin-6 (IL-6), and C-reactive protein (CRP) in the sivelestat sodium group were all greater than those in the control group. The differences were all statistically significant (all P<0.05); The mechanical ventilation time [(5.31±4.12) d vs (7.17±2.32)d] and ICU stay [(6.31±3.42)d vs (8.93±5.26)d] of patients in the sivelestat sodium group were significantly shorter than those in the control group, and the differences were statistically significant (all P<0.05). There was no statistically significant difference in the 28-day mortality rate between the sivelestat sodium group [20.00%(6/30)] and the control group [43.33%(13/30)] ( P>0.05). The total effective rate of treatment in the sivelestat sodium group was significantly higher than that in the control group [80.00%(24/30) vs 56.67%(17/30)], and the difference was statistically significant (χ 2=4.167, P=0.041). Conclusions:Sivelestat sodium is helpful in improving the physiological parameters of patients with ARDS, effectively reducing the levels of inflammatory factors in the body, shortening the duration of mechanical ventilation and ICU stay, but has no significant effect on the 28-day mortality rate.

The incidence rate of aortic dissection (AD) is low, but it is highly fatal in the acute phase. Miss diagnosis and misdiagnosis can occur occasionally, resulting the miss of the best intervention time. Research on the epidemiological characteristics and of AD and related risk factors can identify high-risk groups, make screening and diagnosis as soon as possible and effectively control the changeable risk factors to reduce the incidence of AD and improve the outcome of AD cases. This paper summarizes the progress in research of the epidemiological characteristics of AD and related risk factors in order to promote early prevention and diagnosis of AD, improve the AD case management and intervention level.

ObjectiveTo investigate the association of liver stiffness measurement (LSM) and serum biochemical parameters with hepatic steatosis, liver inflammation, and liver fibrosis in patients with nonalcoholic steatohepatitis (NASH). MethodsA total of 520 patients with NASH who were treated in The Fifth Medical Center of Chinese PLA General Hospital from January 2007 to December 2018 were enrolled, and according to body mass index (BMI) with a cut-off value of 28 kg/m2, the patients were divided into obese group with 151 patients and non-obese group with 369 patients. All patients underwent liver biopsy, and LSM was measured within 3 days before biopsy. Serum biochemical parameters and general clinical data were collected before liver biopsy, and the noninvasive indices aspartate aminotransferase to platelet ratio index (APRI) and fibrosis-4 (FIB-4) were calculated. The t-test was used for comparison of normally distributed continuous between groups, the nonparametric Mann-Whitney U test was used for comparison of non-normally distributed continuous between groups; the chi-square test was used for comparison of categorical data between groups. A Spearman rank correlation analysis was also performed. ResultsAlanine aminotransferase (ALT), aspartate aminotransferase, LSM, controlled attenuation parameter (CAP), spleen length, and APRI gradually increased with the increase in BMI (all P＜0.05). The Spearman correlation analysis showed that LSM, ALT, BMI, and CAP were positively correlated with the degree of hepatic steatosis (r=0.263, 0.327, 0.184, and 0.452, all P＜0.05); LSM, ALT, and CAP were positively correlated with the degree of liver inflammation (r=0.357, 0.278, and 0.121, all P＜0.05); LSM, ALT, BMI, and CAP were positively correlated with the degree of liver fibrosis (r=0.500, 0.216, 0.248, and 0.101, all P＜0.05); age was negatively correlated with the degree of hepatic steatosis, liver inflammation, and liver fibrosis (r=-0.344, -0.129, and -0.163, all P＜0.05). ConclusionLSM, CAP, ALT, and age are significantly correlated with the degree of liver inflammation, liver fibrosis, and hepatic steatosis in NASH patients, and therefore, they can be used in noninvasive diagnostic and predictive models to access the severity of liver injury.

Objective: In order to understand the current situation and influencing factors of teaching quality in a Medical University in Yunnan, thus improving the teaching quality of the teachers. Methods: The self-made evaluation forms for teachers' teaching quality which include 9 first-level indicators were adopted. In December 2016, a survey was conducted on some students from grade 2013 to 2016 about the teachers who gave them lectures from September to December 2016, involving 7 different majors, 23 teachers and 18 courses. SPSS 21.0 was used for data analysis. Enumeration data were described by frequencies and percentages. Univariate and multivariate Logistic regression analyses were used for satisfaction. Results: There were 1 542 valid questionnaires collected in this survey. Univariate Logistic regression analysis showed that there were 6 factors related to the overall satisfaction of teachers' classroom teaching quality, which were "whether the courses are professional (OR=1.430)", "curriculum difficulty (OR=1.731)", "curriculum progression (OR=1.620)", "learning time after class (OR=1.141)", "interest before class (OR=1.565)", and "interest after class (OR=2.291)", respectively. Conclusion "courses are professional", "courses are too easy", and "the progression of courses is slow " are favorable factors for high satisfaction degree, while "courses are set up by the departments that the students belong", "learning time used after class is too short", and "interest for study is decreased after class" may be unfavorable factors for high satisfaction degree.

Objective: To investigate the methods for qualitative pathological assessment of dynamic changes in liver fibrosis/cirrhosis after antiviral therapy in patients with chronic hepatitis B (CHB), since antiviral therapy can partially reverse liver fibrosis and cirrhosis caused by hepatitis B and semi-quantitative, rather than qualitative, pathological assessment is often used for the research on liver fibrosis regression. Methods: Previously untreated CHB patients with liver fibrosis and cirrhosis were enrolled, and liver biopsy was performed before treatment and at 78 weeks after the antiviral therapy based on entecavir. The follow-up assessment was performed once every half a year. Based on the proportion of different types of fibrous septum, we put forward the new qualitative criteria called P-I-R classification (predominantly progressive, predominantly regressive, and indeterminate) for evaluating dynamic changes in liver fibrosis. This classification or Ishak fibrosis stage was used to evaluate the change in liver fibrosis after treatment and Ishak liver inflammation score was used to evaluate the change in liver inflammation after treatment. Results: A total of 112 CHB patients who underwent liver biopsy before and after treatment were enrolled, and among these patients, 71 with an Ishak stage of ≥3 and qualified results of live biopsy were included in the final analysis. Based on the P-I-R classification, 58% (41/71) were classified as predominantly progressive, 29% (21/71) were classified as indeterminate, and 13% (9/71) were classified as predominantly regressive; there were no significant differences between the three groups in alanine aminotransferase, aspartate aminotransferase, albumin, HBeAg positive rate, HBV DNA, and liver stiffness (P < 0.05). After treatment, the proportion of predominantly progressive, indeterminate, or predominantly regressive patients changed to 11% (8/71), 11% (8/71), and 78% (55/71), respectively. Among the 35 patients who had no change in Ishak stage after treatment, 72% (25/35) were classified as predominantly regressive and had certain reductions in the Laennec score, percentage of collagen area, and liver stiffness. Conclusion This new P-I-R classification can be used to assess the dynamic changes in liver fibrosis after antiviral therapy in CHB patients.

Objective To evaluate the relationship between the hepatic toxicity induced by chemotherapy in patients with malignant tumor who test positive for HBV markers. Methods From January 2008 to January 2014, 887 cancer patients were treated by chemotherapy. Among 274 cases of patients were HBV positive (positive group), 613 patients were HBV negative (negative group), the liver function after chemotherapy were compared. Results Positive group patients receiving chemotherapy had higher rate of hepatic toxicity than those in negative group (24.1% vs. 11.3%,P<0.01),the incidence rate of 3-4 grade hepatic toxicity in positive group patients was 11.2%(13/116),more than that in negative group 0.65%(4/613). In the different treatment, there were statistically significant in two groups by TP regimen(paclitaxel+cisplatin), CAF(cyclophosphamide+adriamycin+5-Fluorouracil), CHOP(cyclophosphamide+doxorubicin+oncovin+prednisone)liver function after chemotherapy (P<0.05). In the TP scheme leaded to the incidence of abnor-mal liver function was the highest, the incidence rate in positive group was 36%(18/50),the incidence rate in negative group was 15.8%(19/120). Conclusion HBV infection is associated with higher risk of hepatic toxicity in patients with malignant tumor during chemotherapy(led by TP scheme).
