OBJECTIVE To explore the efficacy and safety of ruxolitinib in the treatment of myelofibrosis （MF）. METHODS A retrospective collection of data was conducted on 42 MF patients who were treated with ruxolitinib in a standardized manner for more than 6 months in the Third People’s Hospital of Bengbu from September 2018 to April 2024. The clinical symptom scores， spleen size reduction， and MF grading of the patients before and after treatment were analyzed. Additionally， the occurrence of adverse reactions with a causality assessment result of “definite”“probable” or “possible” was recorded. The patients’ survival status was followed up. RESULTS After 6 months of treatment， both clinical symptom scores and the total score were significantly decreased than before treatment （P＜0.05）. The length and thickness of the spleen were significantly shorter than before treatment （P＜0.05）. MF classification in 5 patients decreased by 1 level compared with baseline， 1 case was level 2 and dropped to level 0， 14 patients remained stable. The main adverse reactions were anemia （26 cases）， thrombocytopenia （14 cases）， infection （11 cases）， and gastrointestinal discomfort （9 cases）. Thirty-nine patients survived， with a survival rate of 92.86%. CONCLUSIONS Ruxolitinib can effectively improve the clinical symptoms of patients with MF， shrink the spleen， stabilize and even improve MF grading， and holds promise for bringing long-term survival benefits to MF patients. Adverse reactions are mainly anemia， thrombocytopenia， infection and gastrointestinal discomfort.

Astrocytes in the spinal dorsal horn (SDH) exhibit diverse reactive phenotypes under neuropathic conditions, yet the mechanisms driving this diversity and its implications in chronic pain remain unclear. Here, we report that spared nerve injury (SNI) induces marked upregulation of both complement component 3 (C3⁺, A1-like) and S100 calcium-binding protein A10 (S100A10⁺, A2-like) astrocyte subpopulations in the SDH, with elevated microglial cytokines including interleukin-1α, tumor necrosis factor-α, and complement component 1q. Transcriptomic, immunohistochemical, and Western blot analyses reveal co-activation of multiple reactive astrocyte states over a unidirectional shift toward an A1-like phenotype. Fibroblast growth factor 8 (FGF8), a neuroprotective factor via FGFR3, mitigated microglia-induced C3⁺ astrocyte reactivity in vitro and suppressed spinal C3 expression and mechanical allodynia following intrathecal administration in SNI mice. These findings reveal a microglia-astrocyte signaling axis that promotes A1 reactivity and position FGF8 as a promising therapeutic candidate for neuropathic pain by modulating astrocyte heterogeneity.

Objective:To analyze the clinical characteristics of warfarin-related nephropathy (WRN).Methods:Medical records of patients with WRN admitted to Linyi People′s Hospital Affiliated to Shandong Second Medical University from January 1, 2020 to December 31, 2024 were collected. The patients′ basic information (gender, age), warfarin medication details (indications, dosage, frequency, etc.), comorbidities, concomitant medication usage, international normalized ratio (INR) and serum creatinine (Scr) test results before and after the occurrence of WRN, as well as the clinical manifestations, interventions, and outcomes of WRN were extracted. The causal relationship between warfarin and renal dysfunction was evaluated according to the Adverse Drug Reaction Reporting and Monitoring Manual. The clinical data of patients were descriptively and statistically analyzed. Results:A total of 11 patients were entered in the analysis, including 7 males and 4 females; the age ranged from 49 to 85 years, with a median age of 70 years, and 9 cases were older than 60 years. The causality evaluation showed that 3 patients were definite and 8 patients were probable. All the 11 patients had at least one comorbidity, including 6 cases of heart failure, 6 cases of hypoproteinemia, 4 cases of chronic kidney disease, 3 cases of hypertension, 3 cases of pulmonary infection, and 1 case of diabetes. Seven patients were treated with warfarin combined with broad-spectrum antibiotics, 6 combined with diuretics, and 3 combined with renin angiotensin system blockers. The time from the highest INR to the highest Scr level was 0-6 days, with a median time of 2 days, and it was ≤2 days in 9 patients. Six patients had bleeding manifestations such as microscopic hematuria, melena, epistaxis, hematochezia, and skin ecchymosis. Among the 11 patients, 10 stopped warfarin immediately and 1 reduced dosage. All patients received different doses of vitamin K 1 according to the INR level. Among the 6 patients of bleeding, 4 received symptomatic treatments such as omeprazole, tranexamic acid, somatostatin, thrombin powder and octreotide, and 2 patients received hemodialysis due to high Scr level. One patient with severe anemia received blood transfusion. After 1-5 days of treatments (with a median time of 2 days), the INR in all patients decreased to <3.00, of which 5 patients continued to take warfarin, 1 changed warfarin to rivaroxaban, and 5 did not continue anticoagulation therapy. After 2 to 14 days of treatments, Scr in 8 patients recovered to the reference value range, and Scr in 3 patients was still at a high level, of which 1 patient died of unexplained cardiac arrest. Conclusions:WRN is a common adverse reaction of warfarin, with or without bleeding. After the occurrence of WRN, the drug should be stopped as soon as possible and symptomatic treatment should be given. The prognosis is generally good, but it may also lead to chronic kidney disease.

Objective To explore the current status of posttraumatic growth (PTG) among nurses at psychiatric department and analyze its latent profiles and population characteristics. Methods A total of 357 nurses from psychiatric departments of five tertiary Grade A hospitals were selected as the research subjects using the convenience sampling method. The PTG and professional quality of life were studied using the Posttraumatic Growth Inventory and the Chinese version of the Compassion Fatigue Scale. Results The PTG score of the nurses was (56.6±23.2). The scores of compassion satisfaction, burnout, and secondary traumatic stress among nurses were (32.6±7.2), (26.9±5.9), and (26.0±5.4), respectively. The result of potential profile analysis showed that the nurses could be divided into three latent profiles based on PTG levels: low PTG group (34.4%), moderate PTG group (44.0%), and high PTG group (21.6%). The results of multinomial logistic regression analysis showed that the nurses who slept 7-8 hours per day were at higher risk of being in the high PTG group compared with those who slept more than eight hours per day (P<0.05). Psychiatric nurses who took regular exercise were at higher risk of being in the high PTG group compared with those who took irregular exercise (P<0.05). The nurses who had high job satisfaction scores were at higher risk of being in the high PTG group compared with those who had low job satisfaction scores (P<0.01). The nurses with higher compassion satisfaction scores increased the risk of being in the high PTG group compared with those with lower compassion satisfaction scores (P<0.01). The nurses with higher burnout scores increased the risk of being in the low PTG group compared with those with lower burnout scores (P<0.01). Conclusion The PTG characteristics of the nurses exhibit heterogeneity and can be categorized into three distinct profiles. Sleep duration, regular exercise, job satisfaction, compassion satisfaction, and burnout are influencing factors for the PTG latent profiles of nurses working at psychiatric department.

Objective To explore the difference in efficacy of metoprolol versus ivabradine in the treatment of postural orthostatic tachycardia syndrome(POTS)in the elderly after COVID-19 infection.Methods A total of 110 patients diagnosed with POTS at our department from Decem-ber 1,2022 to January 31,2023 were included.According to their drug regimen,they were divided into metoprolol group(62 patients)and ivabradine group(48 patients).On the 28th day of out-patient follow-up,the resting heart rate,heart rate of 10 min of standing,symptom disappearance rate,hospitalization rate,and mortality rate were compared between the two groups.Results On the 28th day of treatment,the resting heart rate and postural heart rate for 10 min were decreased in both groups when compared with the levels at initial diagnosis(P＜0.01).And there were no significant differences in the two types of heart rate between the two groups on the 28th day(71.0±7.0 vs 72.1±7.0,P=0.401;76.5±7.2 vs 77.4±7.6,P=0.573).No obvious differences were observed between the two groups in symptom disappearance rate,hospitalization rate,or mortality rate(88.7％vs 89.6％,3.2％vs2.1％,0％vs 0％,P＞0.05).Conclusion Metoprolol and ivabradine can effectively treat POTS in the elderly patients after COVID-19 infection.

Objective To develop an Oral Health Caring Ability Assessment Scale for Infants and Young Children Caregivers and test its reliability and validity,so as to provide a scientific tool for assessing the oral health caring ability of them.Methods Based on the IMB Skills Model,the initial version of the scale was formed through literature review,expert consultation,and pre-investigation.From May to July 2023,a total of 218 caregivers of infants and young children who were treated in the child health department of a tertiary A specialized hospital in Qingdao were selected by convenience sampling for project analysis and reliability and validity test.From August to September 2023,we selected 330 caregivers of infants and young children who were treated in the child health department of 3 tertiary A general hospitals in Shandong and Hunan Provinces by convenience sampling to further verify the stability of the scale structure.Results The Oral Health Caring Ability Assessment Scale for Caregivers of Infants and Young Children included 4 dimensions,including feeding knowledge,oral cleaning and examination knowledge,oral health caring attitude and oral health caring behavior skills,with a total of 27 items.According to exploratory factor analysis,4 common factors were extracted and the cumulative variance contribution rate was 62.022％.The Cronbach's α coefficient of the questionnaire was 0.938;the split-half reliability was 0.774;the test-retest reliability was 0.990.The content validity index at the scale level was 0.957,and the content validity index at the item level was 0.833-1.000.Confirmatory factor analysis showed that the model fitted well and the factor structure of the scale was stable.Conclusion The Oral Health Caring Ability Assessment Scale for Caregivers of Infants and Young Children has good reliability and validity,which can be used to assess the level of oral health caring ability for caregivers of infants and young children accurately.
