Objective To explore the relationship between lactate dehydrogenase to albumin ratio(LAR)and short-term prognosis in patients with sepsis-associated acute kidney injury(AKI).Methods A retrospective analysis was conducted on 463 sepsis patients treated in the intensive care unit(ICU)of Beijing Shijitan Hospital,Capital Medical University,from January 2018 to June 2022.The patients were divided into two groups:a group with secondary AKI(AKI group)and the one without acute kidney injury(non-AKI group).Acute Physiology and Chronic Health Evaluation Ⅱ(APACHEⅡ),Sequential Organ Failure Assessment(SOFA),and levels of procalcitonin(PCT),C-reactive protein(CRP),serum creatinine(SCr),lactate dehydrogenase(LDH),and albumin(ALB)were compared between the two groups.Multivariate logistic regression analysis was used to determine prognostic factors for sepsis-associated acute kidney injury,and Receiver Operating Characteristic(ROC)analysis was performed to assess the predictive value of APACHE Ⅱ score,SOFA score,PCT,SCr,and lactate dehydrogenase to albumin ratio(LAR)for short-term prognosis of sepsis-associated acute kidney injury.Results The 28-day mortality rate in the non-AKI group was lower than that in the AKI group,and the length of stay in ICU was shorter in the non-AKI group than in the AKI group(P<0.05).APACHE Ⅱ score,SOFA score,PCT,SCr and LAR were independent influencing factors for 28-days death in patients with sepsis-associated acute kidney injury.The ROC curve analysis showed that LAR level had a higher predictive value for short-term prognosis in patients with sepsis-associated AKI as compared with APACHE Ⅱ score,SOFA score,PCT,and SCr.Conclusions LAR is an independent risk factor for sepsis-associated AKI and is associated with 28-day mortality in patients.

Hepatitis B virus (HBV) infection is a common cause of liver disease in China, and with the continuous progress in the research on antiviral therapy for chronic hepatitis B, the indications for antiviral therapy are constantly expanding. However, there are still controversies over the indications for antiviral therapy in patients with chronic hepatitis B (CHB), especially those with negative HBV. By analyzing the limitations of HBV DNA detection, the risk of HBV reactivation in HBV-negative CHB patients, the risk of disease progression in the DNA-negative population with compensated hepatitis B cirrhosis, antiviral response, and the economic benefits of antiviral therapy, this article proposes the necessity of antiviral therapy for HBV-negative HBsAg-positive patients with compensated hepatitis B cirrhosis.

Objective:To investigate the risk factors of non-alcoholic fatty liver disease (NAFLD) in patients with hormone receptor positive (HR+), human epidermal growth factor receptor 2 negative (HER2-) breast cancer (HR+/HER2-BC) and the impact of NAFLD on the survival of patients.Methods:54 HR+BC patients were enrolled in this study. The liver fat accumulation was examined by magnetic resonance imaging (MRI). The patients were divided into two groups: non-NAFLD and NAFLD. Student's t test or Fisher's test was used to analyze the clinical indicators of the two groups. Logistic univariate and multivariate tests were used to analyze the clinical risk factors related to NAFLD. Receiver operating characteristic curve (ROC curve) was used to further analyze the sensitivity of clinical risk factors to predict the diagnosis of NAFLD. The Disease-free survival (DFS) and Overall survival (OS) of the two groups were analyzed by Log-rank (Mantel-Cox) test. Results:There were 22 NAFLD patients and 32 non-NAFLD patients diagnosed by MRI. Student's t test or Fisher's test showed that BMI, waist circumference, AST, ALT, GGT, TG, LDL and HDL were statistically different between the two groups (all P<0.05). Logistic univariate and multivariate analysis showed that AST ( OR=1.05, 95% CI: 1.02-1.10, P=0.007), GGT ( OR=1.04, 95% CI: 1.01-1.09, P=0.038), TG ( OR=1.03, 95% CI: 1.01-1.06, P=0.011) and HDL ( OR=1.06, 95% CI: 1.01-1.12, P=0.037) were the risk factors associated with NAFLD. ROC curve analysis showed that the combination of AST, GGT, TG and HDL had high sensitivity in predicting NAFLD (AUC=0.869, P<0.05). There was no difference in DFS ( HR=1.830, 95% CI: 0.983-3.409, P=0.057) or OS ( HR=2.482, 95% CI: 0.761-8.093, P=0.132) between the two groups. Conclusion:AST, GGT, TG and HDL are the independent risk factors for NAFLD in HR+BC patients during treatment, but concurrent NAFLD has no significant effect on DFS or OS.

Objective:To analyze the risk factors of recurrent wheezing in children with bronchiolitis and to construct a predictive model.Methods:Prospective research methods was used. One hundred and eighty children with bronchiolitis who were treated in Hefei Eighth People's Hospital from February 2017 to February 2019 were selected as the study subjects, and the included children were separated into a modeling group (126 cases) and a validation group (54 cases) according to 7∶3. The children were followed up for 3 years, and then the modeling group was divided into wheezing group (48 cases) and no wheezing group (78 cases) according to whether the children had recurrent wheezing. The Hosmer-Lemeshow fitting curve and receiver operating characteristic (ROC) curve were drawn to evaluate the validity and accuracy of the constructed prediction model.Results:Multivariate Logistic regression analysis showed that artificial feeding ( OR = 8.838, 95% CI 2.601 to 30.027), family history of allergies ( OR = 6.709, 95% CI 1.825 to 24.665), underlying diseases ( OR = 8.114, 95% CI 1.638 to 40.184), and higher IgE level ( OR = 1.020, 95% CI 1.012 to 1.029) were the independent risk factors for recurrent wheezing in children with bronchiolitis ( P<0.05). The area under the curve of the modeling group was 0.917 (95% CI 0.855 to 0.959), and the sensitivity and specificity were 83.33% and 85.90%, respectively; the area under the curve of the validation group was 0.911 (95% CI 0.847 to 0.954), and the sensitivity and specificity were 89.58% and 79.49%, respectively. Conclusions:Artificial feeding, family history of allergies, underlying diseases, and higher IgE level are the independent risk factors for recurrent wheezing in children with bronchiolitis. The constructed prediction model has good accuracy and validity, and can be used as an effective tool for clinical prediction of recurrent wheezing in children with bronchiolitis.

Hip fractures are among the most common fractures in the elderly, presenting to be a leading cause of disability and mortality. Surgical treatment is currently the main treatment method for hip fractures. The incidence of perioperative malnutrition is increased after hip fractures in the elderly due to the comorbidities, decreased basal metabolic rate, accelerated protein breakdown, weakened anabolism and surgical stress. However, malnutrition not only increases the incidence of postoperative complications, but also leads to increased mortality, indicating an important role of perioperative nursing management of nutrition for the elderly patients with hip fractures. At present, there still lacks scientific guidance and application standards on perioperative nursing management of nutrition for the elderly patients with hip fractures. Therefore, the Orthopedic Nursing Committee of Chinese Nursing Association and the Editorial Board of Chinese Journal of Trauma organized relevant experts to formulate the Expert consensus on perioperative nursing management of nutrition for elderly patients with hip fractures ( version 2023) according to evidence-based medical evidences and their clinical experiences. Fourteen recommendations were made from aspects of nutrition screening, nutrition assessment, nutrition diagnosis, nutrition intervention and nutrition monitoring to provide guidance for perioperative nursing management of nutrition in elderly patients with hip fractures.

Objective:To investigate the correlation between serum miR-122-5p and FOXO3 levels and osteoporosis (OP) in postmenopausal women with non-alcoholic fatty liver disease (NAFLD) .Methods:The clinical data and serum of 30 postmenopausal women with NAFLD and 48 postmenopausal women with no-NAFLD were collected. The levels of miR-122-5p and FOXO3 in serum were detected by qRT-PCR. Triglycerides, high-density lipoproteins, and low-density lipoproteins were detected by biochemical autoanalyzer. The bone mineral density of lumbar vertebrae 1-4, Wards triangular bone, femoral neck, greater trochanter and total hip was detected by bone mineral density analyzer. The correlation between the above clinical indicators and OP was analyzed.Results:The expression of miR-122-5p in postmenopausal female NAFLD patients (0.76±0.28) was lower than that in non-NAFLD patients (1±0.31) ( t=3.43, P=0.001) . The downstream target gene FOXO3 of miR-122-5p was identified by bioinformatics website analysis. The expression of FOXO3 in postmenopausal female NAFLD patients (1.31±0.30) was higher than that in non-NAFLD patients (1±0.27) ( t=4.73, P<0.001) . Student’ s t test and Logistic regression analysis showed that triglyceride, miR-122-5p and FOXO3 levels were risk factors for NAFLD (all P<0.05) . Pearson correlation coefficient showed that miR-122-5p level was significantly positively correlated with BMD of femoral neck ( r=0.488, P=0.006) , greater trochanter ( r=0.367, P=0.046) and whole hip ( r=0.404, P=0.027) . FOXO3 level was negatively correlated with bone mineral density of femoral neck ( r=-0.445, P=0.014) and whole hip ( r=-0.507, P=0.004) , while other indexes were not significantly correlated (all P>0.05) . Conclusion:Decreased serum miR-122-5p level and increased FOXO3 level in postmenopausal women with NAFLD may increase the risk of OP.

【Objective】 To investigate the impact of long non-coding RNA (lncRNA) FGD5-AS1 on the malignant biolo-goical behavior of bladder cancer (BC) cells by regulating micro RNA (miR)-129-5p/cyclin dependent kinase 6 (CDK6) axis. 【Methods】 Human BC cell line T24 was cultured from tumor tissue and paracancerous tissue of 105 patients with confirmed BC. The expressions of FGD5-AS1, miR-129-5p and CDK6 mRNA in tissue samples and T24 cells were detected with RT-qPCR. T24 cells were randomly divided into control group, si-NC group, si-FGD5-AS1 group, si-FGD5-AS1+inhibitor NC group and si-FGD5-AS1+miR-129-5p inhibitor group. The cell viability, migration, invasion andapoptosis were detected with CCK-8, Wound healing test, Transwell assay and flow cytometry, respectively. The expressions of Bax, Bcl-2, Caspase3 and CDK6 were detected with Western blot. The relationship between FGD5-AS1 and miR-129-5p, between miR-129-5p and CDK6 were verified with double luciferase reporter gene experiment. 【Results】 FGD5-AS1 and CDK6 mRNA were highly expressed in BC tissue, while miR-129-5p was lowly expressed (P<0.05). After FGD5-AS1 silencing, the expression of FGD5-AS1,A450 value, cell scratch healing rate, cell invasion number, and expressions of Bcl-2 and CDK6 were significantly lower, while the apoptosis rate and expressions of miR-129-5p, Bax and Caspase3 were significantly higher (P<0.05). Inhibition of miR-129-5p expression reversed the effects of FGD5-AS1 silencing on various indexes of BC cells (P<0.05). FGD5-AS1 negatively regulated the expression of miR-129-5p, and miR-129-5p negatively regulated the expression of CDK6. 【Conclusion】 Silencing FGD5-AS1 may inhibit the expression of CDK6 protein by up-regulating miR-129-5p, thus inhibiting the proliferation, migration and invasion of BC cells and promoting cell apoptosis.

Objective:To study the clinical characteristics of patients with brucella bloodstream infection in different age groups, and provide a basis for clinicians to take targeted diagnosis and treatment measures. Methods:Demographic data and general condition (age, sex, occupation, location, onset season, source of infection, clinical stage), clinical characteristics (main clinical symptoms and complications), and laboratory test results (routine and pathogenic tests) of adult patients with brucella bloodstream infection admitted to the Affiliated Hospital of Chengde Medical College from January 2015 to January 2020 were collected. According to the age stratification standards recommended by the World Health Organization, the patients were divided into a young group (18 - 44 years old), a middle-aged group (45 - 59 years old), and an elderly group (≥60 years old), and various indicators among different age groups were compared and analyzed. Results:A total of 75 patients were included, including 15 cases (20.00%) in the young group, 37 cases (49.33%) in the middle-aged group, and 23 cases (30.67%) in the elderly group. Among them, 61 cases (81.33%) were males and 14 cases (18.67%) were females, with statistically significant differences in gender ratios among different age groups (χ 2 = 7.28, P = 0.021). The majority of patients were farmers (64 cases, 85.33%), and 92.00% (69/75) of the patients came from rural areas. The main sources of infection were infected cattle and sheep, and contaminated food (39 cases, 52.00%). The main season of onset was spring and summer (45 cases, 60.00%). The clinical staging was mainly in the acute phase (66 cases, 88.00%). In terms of clinical symptoms, the young group of patients had no symptoms of low back pain, while the incidence rates of low back pain in the middle-aged and elderly groups were 35.14% (13/37) and 30.43% (7/23), respectively. There was a statistically significant difference between the three groups (χ 2 = 6.98, P = 0.031). In terms of complications, there were no cases of concurrent spondylitis in the young group of patients. The incidence rates of spondylitis in the middle-aged and elderly groups were 32.43% (12/37) and 34.78% (8/23), respectively. There was a statistically significant difference among the three groups (χ 2 = 6.86, P = 0.032). In terms of routine laboratory examinations, there were statistically significant differences in the proportion of blood lymphocytes and albumin levels among patients of different age groups ( F = 3.41, 3.27, P = 0.038, 0.044). In terms of pathogenic examination, there was a statistically significant difference in the median alarm time for positive blood culture among patients of different age groups ( H = 9.54, P = 0.008), with the middle-aged group having the longest (66.24 h) and the elderly group having the shortest (58.80 h). Conclusions:The clinical characteristics of patients with brucella bloodstream infection vary among different age groups, middle-aged and elderly patients are prone to low back pain symptoms, accompanied by spondylitis. Clinicians should pay attention to the patient's own characteristics and provide targeted diagnosis and treatment.

Pulmonary blast injury has become the main type of trauma in modern warfare, characterized by externally mild injuries but internally severe injuries, rapid disease progression, and a high rate of early death. The injury is complicated in clinical practice, often with multiple and compound injuries. Currently, there is a lack of effective protective materials, accurate injury detection instrument and portable monitoring and transportation equipment, standardized clinical treatment guidelines in various medical centers, and evidence-based guidelines at home and abroad, resulting in a high mortality in clinlcal practice. Therefore, the Trauma Branch of Chinese Medical Association and the Editorial Committee of Chinese Journal of Trauma organized military and civilian experts in related fields such as thoracic surgery and traumatic surgery to jointly develop the Clinical treatment guideline for pulmonary blast injury ( version 2023) by combining evidence for effectiveness and clinical first-line treatment experience. This guideline provided 16 recommended opinions surrounding definition, characteristics, pre-hospital diagnosis and treatment, and in-hospital treatment of pulmonary blast injury, hoping to provide a basis for the clinical treatment in hospitals at different levels.
