This article reports a case of primary splenic lymphoma misdiagnosed as Sjogren’s syndrome with liver cirrhosis， in order to improve the understanding of primary splenic lymphoma， Sjogren’s syndrome， and liver cirrhosis and avoid misdiagnosis and treatment delay.

Hypoxic-ischemic (HI) brain damage poses a high risk of death or lifelong disability, yet effective treatments remain elusive. Here, we demonstrated that miR-100-5p levels in the lesioned cortex increased after HI insult in neonatal mice. Knockdown of miR-100-5p expression in the brain attenuated brain injury and promoted functional recovery, through inhibiting the cleaved-caspase-3 level, microglia activation, and the release of proinflammation cytokines following HI injury. Engineered extracellular vesicles (EVs) containing neuron-targeting rabies virus glycoprotein (RVG) and miR-100-5p antagonists (RVG-EVs-Antagomir) selectively targeted brain lesions and reduced miR-100-5p levels after intranasal delivery. Both pre- and post-HI administration showed therapeutic benefits. Mechanistically, we identified protein phosphatase 3 catalytic subunit alpha (Ppp3ca) as a novel candidate target gene of miR-100-5p, inhibiting c-Fos expression and neuronal apoptosis following HI insult. In conclusion, our non-invasive method using engineered EVs to deliver miR-100-5p antagomirs to the brain significantly improves functional recovery after HI injury by targeting Ppp3ca to suppress neuronal apoptosis.

Objective To analyze the management and countermeasures of adverse nursing events in a municipal tertiary hospital in Guangxi Zhuang Autonomous Region.Methods The adverse nursing events in 2023 in a municipal tertiary hospital in Guangxi were retrospectively analyzed.Logistic regression analysis was utilized to identify the causes of these adverse events and propose suitable countermeasures.Results In 2023,a total of 121 adverse nursing events were recorded,with falls being the most prominent(42 cases,accounting for 34.71％),followed by drug extravasation,drug safety incidents and unplanned ex-tubation,accounting for 13.22％,9.92％,and 7.44％respectively.Logistic regression analysis revealed that factors such as age ≥70 years,coexisting diseases,Basel Index score ≤40,pain score ≥4,tube slip risk assessment ≥10,RASS sedation score ≥3,NGASR score ≥9,lost risk assessment score ≥ 7,GCS Coma Scale score ≤8,Stress Injury Assessment Scale score ≤10,and Morse score ≥45 were associated with the risk of adverse nursing events.In addition,inadequate awareness of nursing risks among nursing staff,ineffective patient health education methods,and non-compliance to nursing protocols were identified as primary causes of adverse nursing events.Conclusion Advanced age,combined with other diseases,and hospitali-zation scale assessment results are critical factors for adverse nursing events.Lack of nursing responsibility and risk awareness among nursing staff,inadequate system implementation,and irregular operations can increase the risk.Hospitals should optimize management systems and work processes,enhance nursing staff training,and develop targeted preventive measures for adverse nursing events to improve the quality of nursing management and reduce the risk of adverse nursing events.

Objective To investigate the predictive value of interleukin-33(IL-33),eosinophil chemotactic factor(Eotaxin),soluble scavenger receptor CD163(sCD163)for recurrent wheezing in children with bronchi-olitis.Methods A total of 120 children with bronchiolitis who were treated in Jiamusi Maternal and Child Health Hospital from August 2019 to October 2021 were enrolled in the study.The clinical data of the chil-dren were collected,including demographic factors,birth factors,atopic factors,length of hospital stay,time from symptom onset to visit,and respiratory distress assessment tool(RDAI)score.Respiratory syncytial vi-rus(RSV)and rhinovirus(RV)were detected.Blood samples were collected for detection.Blood test indica-tors included total immunoglobulin E(IgE),white blood cell count(WBC),IL-33,Eotaxin and sCD163.The discharged children were followed up for 1 year,and they were divided into non-recurrent group and recurrent group according to the number of wheezing episodes.The two groups were compared in terms of clinical data and blood test indicators.Logistic regression was used to analyze the risk factors for recurrent wheezing in children with bronchiolitis.Pearson correlation analysis was used to analyze the correlation between blood test indexes and RDAI score.The receiver operating characteristic(ROC)curve was drawn to analyze the value of IL-33,Eotaxin,and sCD163 levels alone and in combination in predicting recurrent wheezing in children with bronchiolitis.Results Compared with the non-recurrent group,the recurrent group had significantly higher RDAI score,higher proportion of patients with a history of eczema,a personal history of allergy,and a signifi-cantly higher RSV infection rate(P＜0.05).The recurrent group had significantly higher levels of IL-33,Eotaxin,and sCD163 than the non-recurrent group(P＜0.05).Pearson correlation analysis showed that the levels of IL-33,Eotaxin,and sCD163 in children with bronchiolitis were positively correlated with RDAI score(r=0.516,0.611,0.522,P＜0.05).Logistic regression analysis showed that RDAI score,history of eczema,personal history of allergy,RSV infection,increased IL-33 levels,increased Eotaxin levels,and increased sCD163 levels were risk factors for recurrent wheezing in children with bronchiolitis(OR＞1,P＜0.05).The ROC curve found that The area under the curve(AUC)of IL-33,Eotaxin,and sCD163 levels alone and in combination for predicting recurrent wheezing in children with bronchiolitis was 0.829(95％CI:0.757-0.901),0.858(95％CI:0.794-0.922),and 0.857(95％CI:0.789-0.925)and 0.954(95％CI:0.921-0.987).Conclusion Increased levels of IL-33,Eotaxin and sCD163 in children with bronchiolitis can increase the risk of recurrent wheezing,and the combined detection of the three can effectively predict the occurrence of recurrent wheezing.

AIM:To evaluate the clinical efficacy and safety of pneumoperitoneum-free single-hole endoscopy combined with ropivacaine local infiltra-tion anesthesia in pregnancy with ovarian tumor.METHODS:Twenty-eight pregnant women with ovarian tumor were randomly divided into two groups:observation group(n=16)and control group(n=12).The first time out of bed,ventilation time,postoperative hospital stay,non-invasive blood pressure,heart rate(HR),respiratory fre-quency(RR)and blood oxygen saturation(SpO2)were compared between the two groups.Pain score,Ramsay sedation score,SAS anxiety score,postoperative complications,patient satisfaction and recovery quality scale QoR15 were evaluated at 6,24 and 48 hours after operation.RESULTS:There was no significant difference in postopera-tive hospital stay,Ramsay score,RR,SpO2 and the incidence of complications between the two groups(P>0.05),but the time of getting out of bed and ventilation time were shortened,the scores of non-invasive blood pressure,HR,pain and anxiety in the observation group were lower than those in the control group,and the scores of patient satisfac-tion and QoR15 in the observation group were bet-ter than those in the control group(P<0.05).CON-CLUSION:The application of pneumoperitoneum-free single-hole endoscope combined with ropiva-caine local infiltration anesthesia in pregnancy with ovarian tumor can reach satisfactory clinical re-sults,including reducing postoperative pain and anxiety,which is worth popularizing.

Microglia, originating from primitive macrophages in the yolk sac, serves as both immune system defenders and regulators of homeostasis. These cells exhibit two primary polarization states: conventionally activated(M1)and alternatively activated(M2). The polarization of microglia plays a crucial role in influencing inflammatory disorders, metabolic imbalances, and neural degeneration. This process is implicated in various aspects of ocular diseases, especially age-related macular degeneration(AMD), including inflammation, oxidative stress and pathological angiogenesis. The distinct functional phenotypes of microglia impact disease progression and prognosis. Thus, regulating the polarization or functional phenotype of microglia at different stages of AMD holds promise for personalized therapeutic approaches. This comprehensive review outlines the involvement of microglia polarization in both physiological and pathological conditions, emphasizing its relevance in AMD. The discussion underscores the potential of polarization as a foundation for personalized treatment strategies for AMD.

Objective To investigate the dietary patterns of rural residents in the high-incidence areas of esophageal cancer (EC), and to explore the clustering and influencing factors of risk factors associated with high-incidence characteristics. Methods A special structured questionnaire was applied to conduct a face-to-face survey on the dietary patterns of rural residents in Yanting county of Sichuan Province from July to August 2021. Univariate and multivariate logistic regression models were used to analyze the influencing factors of risk factor clustering for EC. Results There were 838 valid questionnaires in this study. A total of 90.8% of rural residents used clean water such as tap water. In the past one year, the people who ate fruits and vegetables, soybean products, onions and garlic in high frequency accounted for 69.5%, 32.8% and 74.5%, respectively; the people who ate kimchi, pickled vegetables, sauerkraut, barbecue, hot food and mildew food in low frequency accounted for 59.2%, 79.6%, 68.2%, 90.3%, 80.9% and 90.3%, respectively. The clustering of risk factors for EC was found in 73.3% of residents, and the aggregation of two risk factors was the most common mode (28.2%), among which tumor history and preserved food was the main clustering pattern (4.6%). The logistic regression model revealed that the gender, age, marital status and occupation were independent influencing factors for the risk factors clustering of EC (P<0.05). Conclusion A majority of rural residents in high-incidence areas of EC in Yanting county have good eating habits, but the clustering of some risk factors is still at a high level. Gender, age, marital status, and occupation are influencing factors of the risk factors clustering of EC.

Purpose: Inflammatory myofibroblastic tumor (IMT) is a rare mesenchymal malignancy that occurs primarily in children and adolescents. The clinical and pathological features of IMT in adult patients are not well understood. Materials and Methods: We retrospectively searched for records of adult patients with IMT at Fudan University Shanghai Cancer Center from 2006 to 2021. Clinicopathological data, treatments, and outcomes were collected and analyzed. Results: Thirty adult patients with IMT, mostly women (60.0%), were included. The median age of the patients was 38 (21-77). The most common primary site was abdominopelvic region (53.3%), followed by lungs (20.0%). Seven patients had an abdominal epithelioid inflammatory myofibroblast sarcoma (EIMS). The positivity rate of anaplastic lymphoma kinase (ALK) was 81.5% (22/27). Sixteen patients with advanced ALK-positive disease received crizotinib, with an objective response rate (ORR) of 81.3% and a disease control rate of 87.5%. The median progression-free survival was 20.8 months. EIMS was associated with more aggressive behavior; however, the prognosis was similar to that of non-EIMS patients after treatment with an ALK inhibitor. At a median follow-up time of 30 months (95% confidence interval [CI], 13.6 to 46.4), the 5-year overall survival was 77% (95% CI, 66 to 88) in all patients. Conclusion Adult IMTs appeared more aggressive, with a higher incidence of recurrence and metastases, and patients with EIMS had more aggressive cases. Treatment with ALK inhibitors resulted in a high ORR and a durable response, which suggested that ALK inhibitors could be used as a first-line treatment option in adult patients with ALK-positive advanced IMT.

Objective:To evaluate the efficacy and safety of stereotactic ablative radiotherapy (SABR) in patients with pulmonary oligometastases.Methods:Clinical data of patients with pulmonary metastases treated with SABR from 2011 to 2018 were retrospectively analyzed. The local control rate (LCR) and overall survival (OS) were calculated by Kaplan- Meier method. log-rank test was used for univariate analysis and Cox’s regression model for multivariate analysis. Results:A total of 214 lung metastases were detected in 159 patients, and the median follow-up time was 43 months. The 1-, 3-and 5-year LCR were 90.1%, 73.9% and 65.8%, respectively. The 1-, 3-and 5-year OS were 73.8%, 43.6% and 11.9%, respectively. Univariate analysis showed that biological effective dose (BED)≥100 Gy was significantly correlated with LCR ( P=0.033). Cox’s multivariate analysis showed that BED and primary tumor source were the independent prognostic factors of LCR ( P=0.023, P=0.043). No>grade 3 adverse events were observed in all patients during treatment. Conclusions:SABR is a safe and effective treatment of lung oligometastases. SABR should be actively aD ministered for pulmonary oligometastases, especially for those with lesions from lung cancer and the radiation dose should be selected as BED ≥100 Gy.
