Kupffer cells (KCs), as residents and sentinels of the liver, are involved in the formation of hepatic fibrosis (HF). However, the biological functions of circular RNAs (circRNAs) in KCs to HF have not been determined. In this study, the expression levels of circRNAs, microRNAs, and messenger RNAs (mRNAs) in KCs from a mouse model of HF mice were investigated using microarray and circRNA-Seq analyses. circDcbld2 was identified as a candidate circRNA in HF, as evidenced by its up-regulation in KCs. Silver staining and mass spectrometry showed that Wtap and Igf2bp2 bind to cirDcbld2. The suppression of circDcbld2 expression decreased the KC inflammatory response and oxidative stress and inhibited hepatic stellate cell (HSCs) activation, attenuating mouse liver fibrogenesis. Mechanistically, Wtap mediated the N ⁶-methyladenosine (m6A) methylation of circDcbld2, and Igf2bp2 recognized m6A-modified circDcbld2 and increased its stability. circDcbld2 contributes to the occurrence of HF by binding miR-144-3p/Et-1 to regulate the inflammatory response and oxidative stress. These findings indicate that circDcbld2 functions via the m6A/circDcbld2/miR-144-3p/Et-1 axis and may act as a potential biomarker for HF treatment.

Objective To develop a platform for reporting medication near miss events and evaluate its application effectiveness,aiming to enhance medication safety of patients.Methods Based on literature review,qualitative interviews,and expert group meetings,a medication near-miss event reporting platform was constructed,including 4 modules:event content filling,event risk grading,event handling,and statistical analysis.50 nurses were conveniently selected from the pediatric ward of a tertiary grade A hospital in Henan Province as the application subjects.The reporting situation and filling duration of medication near miss events,the score of the Medication Near Miss Reporting Disorder Scale,and the incidence of medication near miss events were compared after the application of the platform(from March to August 2023)and before the application(from September 2022 to February 2023).Results The reporting rate of medication near miss events after the application of the platform was higher than that before the application of the platform,and the comparison of the distribution of event nature and occurrence links showed statistically significant differences(P＜0.05).After the application of the platform,the reporting duration of medication near miss events was shorter than that before the application of the platform,and the score of the Medication Near Miss Reporting Disorder Scale was lower than that before the application of the platform.The differences were statistically significant(P＜0.001).There was no statistically significant difference in the incidence of medication near miss events before and after the application of the platform(P=0.241).Conclusion Using this platform can help improve the reporting rate of medication near miss events,reduce the time taken to fill out reports,and minimize reporting barriers for nurses.

Objective:To explore the efficacy and safety of the combination therapy of lenalidomide and rituximab (R2) for short-cycle maintenance therapy in patients with B-cell non-Hodgkin lymphoma (B-NHL).Methods:A retrospective case series study was conducted. The clinical data of 19 B-NHL patients who received R2 regimen maintenance therapy after achieving complete remission through chemotherapy or autologous hematopoietic stem cell transplantation at Dongguan Kanghua Hospital from February 2018 to January 2024 were collected, and the overall survival (OS), progression-free survival (PFS), adverse reactions, changes in lymphocyte subsets and cytokine levels before and after treatment were analyzed.Results:Among the 19 patients, there were 7 males and 12 females, with a median age [ M ( Q1, Q3)] of 49 (45, 65) years. The median follow-up time was 56 months, ranging from 5 to 77 months. The 1-year OS and PFS rates were 89.2% and 88.9%, respectively. The 2-year and 5-year PFS rates were both 83.2%, and the 2-year and 5-year OS rates were both 88.9%. Common adverse reactions included hematological adverse reactions and infections, with 4 cases (21.1%) experiencing grade 3-4 hematological adverse reactions and 4 cases (21.1%) experiencing infections. There was no statistically significant difference in the levels of lymphocyte subsets (total T cells, helper T cells, regulatory T cells, NK cells, B cells, and CD4/CD8) and cytokines [interleukin (IL)-2, IL-4, IL-6, IL-10, tumor necrosis factor-α, and interferon-γ] before and after treatment (all P > 0.05). Conclusions:The R2 regimen for short-cycle maintenance therapy of B-NHL is effective and well tolerated by patients.

Objective:To evaluate the therapeutic effects of Yufu ointment for acute radiation-induced skin injury. Methods:We enrolled a total of 104 patients with malignant tumors who developed acute skin injury of grade 2-3 during or after the first course of radiotherapy from June 2019 to February 2023. The observation group ( n=53) and control group ( n=51) received external application of Yufu ointment and Shirun Shaoshang ointment, respectively. We recorded the changes in the grade of skin injury and associated symptoms (such as pain, itching, and burning sensation) and healing speed and time for the two groups. Results:A total of 102 patients completed the study, with 53 cases in the observation group and 49 cases in the control group. The incidence rate of moisture skin lesions in the observation group was significantly lower than that in the control group (62.26% vs. 83.67%, P<0.05). The healing speed of moisture skin ulcerations was significantly faster in the observation group than in the control group (1.67 cm 2/d vs. 0.55 cm 2/d, P<0.05). The observation group had a significantly shorter time to skin injury healing than the control group (10.40 d vs. 14.41 d, P<0.05), significantly different for skin injury of grade 2 (10.21 d vs. 17.57 d, P<0.05) but not for skin injury of grades 2.5 and 3 ( P>0.05). Regarding clinical symptoms, both groups experienced significant reductions in pain and burning sensation scores after treatment ( P<0.05); the grade of itching was significantly decreased for the observation group ( P<0.05), but had no significant change for the control group after treatment ( P>0.05). Conclusions:Yufu ointment can significantly alleviate secondary damage for patients with acute radiation-induced skin injury, by accelerating the healing process and relieving symptoms such as pain, itching, and burning sensation with good tolerability, which deserves further promotion.

Objective:The transjugular or transfemoral approach is used as a common method for hepatic venous pressure gradient (HVPG) measurement in current practice. This study aims to confirm the safety and effectiveness of measuring HVPG via the forearm venous approach.Methods:Prospective recruitment was conducted for patients with cirrhosis who underwent HVPG measurement via the forearm venous approach at six hospitals in China and Japan from September 2020 to December 2020. Patients' clinical baseline information and HVPG measurement data were collected. The right median cubital vein or basilic vein approach for all enrolled patients was selected. The HVPG standard process was used to measure pressure. Research data were analyzed using SPSS 22.0 statistical software. Quantitative data were used to represent medians (interquartile ranges), while qualitative data were used to represent frequency and rates. The correlation between two sets of data was analyzed using Pearson correlation analysis.Results:A total of 43 cases were enrolled in this study. Of these, 41 (95.3%) successfully underwent HVPG measurement via the forearm venous approach. None of the patients had any serious complications. The median operation time for HVPG detection via forearm vein was 18.0 minutes (12.3~38.8 minutes). This study confirmed that HVPG was positively closely related to Child-Pugh score ( r = 0.47, P = 0.002), albumin-bilirubin score ( r = 0.37, P = 0.001), Lok index ( r = 0.36, P = 0.02), liver stiffness ( r = 0.58, P = 0.01), and spleen stiffness ( r = 0.77, P = 0.01), while negatively correlated with albumin ( r = -0.42, P = 0.006). Conclusion:The results of this multi-centre retrospective study suggest that HVPG measurement via the forearm venous approach is safe and feasible.

Subarachnoid hemorrhage (SAH) is the third common type of stroke in the world,and its mortality and disability rates have declined over the past few decades due to the advances in neuroimaging technology and endovascular interventional therapy and promotion of healthy physical examination,but long-term neurological deficits and cognitive impairment of the patients have not significantly improved,which may be related to the white matter injury (WMI) after SAH.Little attention has been paid to WMI after SAH in the past,which may be an important reason for the poor prognosis of the patients with SAH.The neuroin-flammation response is an important pathophysiological process after SAH,and the neuroinflammation after SAH can aggravate WMI.This article reviews the relationship between neuroinflammation and WMI after SAH in order to deepen the understanding of its effects on cognitive function after SAH.

Objective To assess the predictive value of bedside diaphragmatic ultrasound in predicting pulmonary complications(PPCs)after thoracoscopic lobectomy.Methods The patients who had undergone elective thoracoscopic lobectomy in Henan Provincial People's Hospital were collected.General information and perioperative indicators were recorded.Diaphragmatic motility was detected by bedside ultrasound preoperatively and on postopera-tive days 1,3,and 5.The patients were divided into two groups(PPCs group and non-PPCs group).Statistically different parameters in univariate analysis were included in multivariate logistic regression analysis to screen inde-pendent influencing factors of PPCs.Receiver operating curve(ROC)was drawn,and the performance of diaphragm ultrasound for predicting PPCs was evaluated by the area under the curve(AUC).Results 949 patients were included in this study.PPCs occurred in 537 patients(57.5% ).Univariate analysis showed that as compared with the non-PPCs group,the proportion of diabetic patients and postoperative VAS score in the PPCs group increased,time to chest tube removal and one-lung ventilation,and postoperative hospital stay were longer.PPCs group had a lower DE value on the operative side and healthy side on postoperative days 1 and 3 and on the operative side alone on day 5(P<0.05).Multivariate logistic regression analysis showed that prolonged one-lung ventilation time,diabetes mellitus,DE values on the operative side and unoperative side on postoperative days 1 and 3,and decreased DE value on the operative side on day 5 were independent risk factors for PPCs.The ROC curve shows that the efficacy of DE for pre-dicting PPCs on the operative and healthy sides on postoperative days 1 and 3 was relatively high(AUC of 0.797,0.821,0.933,and 0.929;respectively).The efficacy of DE for predicting PPCs on the operative side was poor on postoperative day 5(AUC of 0.703 and 0.512,respectively).Conclusions A decrease in postoperative DE,prolonged one-lung ventilation time,and diabetes are independent risk factors for PPCs after thoracoscopic lobectomy.Bedside ultrasound evaluation of DE has a higher value in predicting PPCs three days after surgery.

【Objective】 To investigate the development of adaptability in children aged 2 - 6, and to explore its influencing factors, so as to provide reference for promoting the development of adaptability in young children. 【Methods】 Data were from the National Nutrition and Health Systematic Survey for Children in China, and 3 319 children aged 2 - 6 and their parents from 28 sites across 14 provinces were recruited in this study.The Development Scale for Children Aged 0 - 6 years (WS/T 580-2017) was used to measure the developmental quotient of children′s adaptive ability, and a survey questionnaire was used to collect relevant information about children and their parents. 【Results】 Among 3 319 children aged 2 - 6, the proportion of slightly low or low level of adaptability, moderate adaptability development, good and excellent adaptability development was 7.68%,66.25% and 26.06%, respectively.The proportion of children aged 5 - 6 with good and excellent adaptability was lower in 3-year-old and 4-year-old groups (χ²=59.29, P<0.05).Multiple stepwise linear regression showed that children′s gender (β=0.06), gestational age of birth (β=-0.05), only child (β=-0.04), left-behind child (β=-0.04), the main caregiver (β=-0.06), and the education level of parents (β=0.09, 0.10), whether parents actively pay attention to children′s emotions (β=-0.06) and whether children play with homemade toys (β=-0.04) were the influencing factors of children′s adaptive development quotient.Girls, full-term children, only children, non-left-behind children, children with parents as main caregivers, parents with a high level of education, parents who often take the initiative to pay attention to children′s emotions, and children who play with homemade toys had a higher level of adaptability development quotient. 【Conclusions】 The development level of adaptability in children aged 2 - 6 in China is mostly above the average level and is related to multiple factors.Targeted intervention work can be carried out on relevant factors in order to promote the development of children′s adaptability.
