ObjectiveTo explore the driving forces for oncology nurses’ participation in palliative care work， thereby providing a theoretical basis for the improvement of education and training， incentive mechanisms， and other aspects of the palliative care nursing staff. MethodsEmploying a qualitative research method， semi-structured interviews lasting 40-60 minutes were conducted with 14 nurses who had participated in palliative care work. The interview data were analyzed using the Colaizzi seven-step analysis method. ResultsInternal positive driving forces were job interest， empathy， and a sense of professional responsibility， while the negative was low psychological resilience. External positive driving forces included high work support， professional identity， mutual benefits for nurses and patients， and positive patient attitudes， whereas negative driving forces comprised busy routine clinical work， lack of a reward and incentive system， and bland or negative patient attitudes. ConclusionIt is essential to provide a flexible platform for the enhancement of nurses’ professional capabilities in palliative care， intensify the publicity of palliative care and death education； intervene and guide nurses’ negative emotions， improve and implement relevant incentive systems， and standardize the job recognition and scope of responsibilities of palliative care nurses.

AIM: To investigate variation patterns of corneal biomechanical parameters and binocular symmetry among children of different genders aged 8-16 years.METHODS:A retrospective study was conducted, and children who underwent optometric examinations at the ophthalmology department of our hospital were enrolled between January 2022 and December 2024. Measurements included the flat keratometry(K1), steep keratometry(K2), and mean curvature(Km)of the anterior corneal surface, horizontal visible iris diameter(HVID), central corneal thickness(CCT), corneal endothelial cell density(CECD), average cell size(ACS), coefficient of variation(CV), and hexagonality(HEX). Corneal parameters and binocular differences were compared between genders and across age groups.RESULTS:A total of 621 children(1 242 eyes)were enrolled in this study, including 284 males(568 eyes), 337 females(674 eyes), 528 children aged 8-12 years(1 056 eyes), and 93 children aged 13-16 years(186 eyes). In children aged 8-16 years, the K1, K2, Km and CV of both eyes, as well as the interocular CCT differences in boys were significantly lower than those in girls(all P<0.05), while the HVID and HEX of both eyes, as well as the CCT of the left eye in boys were significantly higher than those in girls(all P<0.05). Children aged 8-12 years had significantly higher K1, Km, CECD and HEX in both eyes, and significantly lower ACS in both eyes than those aged 13-16 years(all P<0.05). K1, K2, Km, CECD and HEX in both eyes were negatively correlated with age(P<0.05); ACS in both eyes was positively correlated with age(P<0.001); K1 and Km of the right eye were positively correlated with the CECD of the right eye(P<0.05), and K1 and CCT of the left eye were positively correlated with the CECD of the left eye(P<0.05).CONCLUSION:Significant gender differences exist in corneal parameters among children aged 8 to 16 years, while binocular symmetry remained stable.

Tuberculosis (TB), a chronic infectious disease caused by Mycobacterium tuberculosis, is primarily airborne and remains a global health problem, especially in resource-limited countries and regions. The emergence of drug resistance in M. tuberculosis has rendered the existing means ineffective in the treatment of TB. Therefore, research in new therapeutic directions has become imperative. In this review, we outline functional peptides in terms of the mechanisms of action, anti-TB attempts, advantages and disadvantages, and latest advances, aiming to analyze the research progress in anti-TB peptides. Furthermore, we investigate the potential applications of bioactive compounds found in traditional Chinese Medicine within the context of peptides.

Objective To investigate the prevalence and related factors of sarcopenia among non–bedridden older adults in the community of Baoshan District using the China mini sarcopenia risk assessment 7 (C-MSRA-7) combined with Ishii scoring system. Methods The older individuals consulting at 20 community health stations in Baoshan District between April 2025 and June 2025 were enrolled. Data were collected using a general information questionnaire, a dietary and lifestyle habits survey, the C-MSRA-7, and the mini nutritional assessment-short form (MNA-SF). Handgrip strength and anthropometric measurements were also obtained. Individuals with both Ishii score and C-MSRA-7 results positive were classified into the sarcopenia risk group, while the remaining participants were assigned to the non–sarcopenia risk group. Differences in lifestyle habits, dietary patterns, and nutritional status between the two groups were compared. Results A total of 2 611 valid questionnaires were retrieved. Univariate analysis showed statistically significant differences in alcohol consumption, physical activity frequency, body mass index (BMI), nutritional status, activities of daily living, and regularity of three meals in sarcopenia risk group (n＝486) and non–sarcopenia risk group (n＝2 125, P<0.05). Logistic regression analysis showed that advanced age (75–84 years: OR＝2.55, 95%CI 2.03–3.21; ≥85 years: OR＝3.98, 95%CI 2.24–7.07), underweight status (OR＝2.19, 95%CI 1.50–3.19), weight loss＞2 kg (OR＝4.52, 95%CI 2.68–7.64) past 3 months, lack of regular physical activity (OR＝1.77, 95%CI 1.24–2.52) , and alcohol consumption (OR＝1.48, 95%CI 1.07–2.05) were independent risk factors for sarcopenia (P<0.05). Behaviors related to healthy diet, including daily milk consumption (OR＝0.40, 95%CI 0.30–0.52), regular three meals (OR＝0.56, 95%CI 0.41–0.78), and high-quality protein intake (OR＝0.70, 95%CI 0.52–0.94), were protective factors (P<0.05). Conclusions Sarcopenia among community–dwelling, non–bedridden older adults is closely associated with physical activity levels, dietary habits, and nutritional status. Early identification of individuals at risk, enhanced nutritional education, and timely implementation of nutritional interventions and exercise programs are recommended for this population.

Objective: To determine the clinical efficacy of platelet-rich plasma (PRP) injection combined with warm acupuncture and moxibustion for treating patients with knee osteoarthritis and cold dampness obstruction syndrome. Methods: One hundred and twenty-eight patients with knee osteoarthritis and cold dampness obstruction syndrome who visited the Rehabilitation Department and Orthopedics Department of the Second Affiliated Hospital of Anhui University of Chinese Medicine from January 2023 to March 2024 and who met the inclusion and exclusion criteria were randomly divided into an experimental (n=64) and control group (n=64) using the random number table method. The experimental group was treated with PRP injection combined with warm acupuncture and moxibustion, whereas the control group was treated with normal saline injection combined with warm acupuncture and moxibustion treatment. PRP and normal saline injections were administered once every two weeks, a total of four times. Patients were treated with warm acupuncture and moxibustion once a day, six times a week, for four consecutive weeks. The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), Traditional Chinese Medicine (TCM) syndrome, visual analog scale (VAS), and Lysholm scores were determined before treatment, at week 4 and week 8 of treatment, and week 16 of follow-up. Serum interleukin-6 (IL-6), matrix metalloproteinase-3 (MMP-3), tumor necrosis factor-α (TNF-α), osteoprotegerin (OPG), bone gla protein(BGP), and cartilage oligomeric matrix protein (COMP) levels were compared between the two groups before and after 8 weeks of treatment. The clinical efficacy and safety indicators between the two groups were also compared. Results: There was no statistical difference in baseline data such as gender, age, disease duration, and body mass index between the two groups of patients. Compared with before treatment, both groups showed decreased WOMAC total and subscale, TCM syndrome total score and symptom scores, and VAS scores, and an increase in Lysholm scores at 4, 8, and 16 weeks after treatment. After treatment, serum IL-6, MMP-3, TNF-α, and COMP levels decreased, whereas serum OPG and BGP levels increased (P<0.05). Compared with the control group, patients in the experimental group showed decreased WOMAC total and subscale, TCM syndrome total score and symptom scores, and VAS scores, and an increase in Lysholm score at 4, 8, and 16 weeks after treatment. Compared with the control group, patients in the experimental group showed decreased serum IL-6, MMP-3, TNF-α, and COMP levels and an increase in serum OPG and BPG levels after treatment (P<0.05). The total effective rate of the experimental group was 91.94%, higher than that of the control group (81.97%; P<0.05). Conclusion PRP injection combined with warm acupuncture and moxibustion can improve various TCM symptoms, improve knee joint function and bone metabolism, and reduce inflammation in patients with knee osteoarthritis and cold dampness obstruction syndrome.

The accumulation of uremic toxins such as urea nitrogen, blood creatinine, and uric acid of patients with renal failure in vivo would lead to aggravated kidney damage. In this study, coated aldehyde oxy-starch (CAO) was used as an adsorbent to investigate its in vitro adsorption performance on renal failure indexes for urea, indoxyl sulfate (INS), monomethylamine (MMA), dimethylamine (DMA), uric acid (UA), and creatinine (Cr). The effects of variables such as pH, temperature, concentration, dosage, and time on the adsorption capacity of CAO were systematically investigated, employing analytical techniques of high-performance liquid chromatography (HPLC) and gas chromatography (GC). The results revealed that CAO exhibited a strong adsorption capacity for urea, INS, and MMA, alongside a moderate adsorption capacity for DMA, UA, and Cr. The adsorption kinetics and thermodynamic studies indicated that the adsorption of urea and UA by CAO were fitted in pseudo-first-order kinetics, and the adsorption isotherm aligned with the Freundlich adsorption model. The enthalpy change ΔH of urea in adsorption was in the range of 40 to 60 kJ·mol^-1, which demonstrated the presence of strong adsorption force due to the interactions of coordinating groups. The ΔH of UA was greater than 80 kJ·mol^-1, indicating the generation of chemical bonds during the adsorption. Both of them, Gibbs free energy ΔG was less than 0, within the range of -20 to 0 kJ·mol^-1, suggested that the adsorption of urea and UA by CAO occurred spontaneously as physical adsorption process. The adsorption entropy ΔS of urea and UA was > 0, which indicated an increase in entropy throughout the adsorption. The infrared spectroscopygram showed the formation of a chemical bond, specifically the imine bond, following the adsorption of urea by CAO, thereby indicating a chemical reaction during the adsorption. This study elucidates the adsorption mechanism of CAO on various indexes of renal failure, providing a scientific basis for its clinical usage.

ObjectiveTo observe the effects of modified Chaihu Shugansan on the calmodulin-dependent protein kinase Ⅱ（CaMKⅡ）/cAMP-response element binding protein （CREB） signaling pathway in the hippocampus and heart tissue of a rat model with myocardial ischemia and depression and explore the mechanism by which this formula prevents and treats coronary heart disease combined with depression. MethodsThe model of myocardial ischemia combined with depression was established by high-fat diet， intraperitoneal injection of isoproterenol （ISO）， and chronic unpredictable mild stress （CUMS）. A total of 108 SD male rats were randomly divided into normal group， model group， high （23.4 g·kg^-1）， medium （11.7 g·kg^-1）， and low （5.85 g·kg^-1） dose groups of modified Chaihu Shugansan， CaMKⅡ inhibitor （KN93） group， and KN93 + high， medium， and low dose groups of modified Chaihu Shugansan， with 12 rats in each group. From the first day of modeling to the end of modeling， drugs were administered once a day. In the seventh and eighth weeks， the KN93 group and the KN93 + high， medium， and low dose groups of modified Chaihu Shugansan were intraperitoneally injected with KN93 three times weekly. At the end of the eighth week， behavioral tests including sucrose preference， open field， and elevated plus maze were conducted. Electrocardiogram （ECG） lead Ⅱ changes were observed in each group of rats， and hematoxylin-eosin （HE） staining was performed to observe changes in heart tissue. Serum levels of triglycerides （TG）， total cholesterol （TC）， high-density lipoprotein （HDL）， low-density lipoprotein （LDL）， and lactate dehydrogenase （LDH） were measured by using an enzyme-labeled instrument. Creatine kinase （CK） and creatine kinase-MB （CK-MB） were detected by ultraviolet spectrophotometry， while serum monocyte chemoattractant protein-1 （MCP-1） was measured by enzyme-linked immunosorbent assay （ELISA）. Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） was used to detect mRNA expression of CaMKⅡ and CREB in hippocampal and heart tissue， and Western blot was performed to assess protein expression of CaMKⅡ， phosphorylated （p）-CaMKⅡ， CREB， and p-CREB. ResultsCompared to the normal group， the model group showed significant reductions in sucrose preference rate， total activity distance in the open field， number of entries into the center area of the open field， and percentage of entries into the open arms of the elevated plus maze （P<0.01）. The ECG showed ST-segment elevation， and HE staining showed serious degeneration of myocardial fibers， disordered arrangement， and infiltration of a large number of inflammatory cells. In addition， serum TC and LDL levels increased （P<0.01）， and HDL level decreased （P<0.01）. CK， CK-MB， LDH， and MCP-1 levels significantly increased （P<0.05， P<0.01）. The mRNA expression of CaMKⅡ and CREB and the protein expression of p-CaMKⅡ and p-CREB decreased in the hippocampal tissue （P<0.05， P<0.01）， but those increased in the heart tissue （P<0.01）. Compared to the model group， the high， medium， and low dose groups of modified Chaihu Shugansan showed improvements in these abnormalities. The KN93 group had reduced sucrose preference， total activity distance in the open field， number of entries into the center area of the open field， and percentage of entries into the open arms of the elevated plus maze （P<0.01）， as well as decreased serum CK， CK-MB， LDH， and MCP-1 levels （P<0.05， P<0.01）. KN93 also reduced ST-segment elevation， alleviated the degeneration degree of myocardial fibrosis， and lowered inflammatory cell infiltration. The mRNA expression of CaMKⅡ and CREB and the protein expression of p-CaMKⅡ and p-CREB in both the hippocampal and heart tissue were reduced （P<0.05， P<0.01）. The KN93 + high， medium， and low dose groups of modified Chaihu Shugansan showed further improvements in these abnormalities compared to the KN93 group. ConclusionThe modified Chaihu Shugansan exerts antidepressant and myocardial protective effects in rats with myocardial ischemia and depression， possibly related to bidirectional regulation of the CaMKⅡ/CREB signaling pathway， with the high-dose modified Chaihu Shugansan showing the best effects.

Objective To investigate the risk factors for lymph node metastasis in resectable lung adenocarcinoma by combining spatial location, clinical, and imaging features, and to construct a lymph node metastasis prediction model. Methods A retrospective study on patients who underwent chest CT at the First Affiliated Hospital of Nanjing Medical University from June 2016 to June 2020 and were surgically confirmed to have invasive lung adenocarcinoma with or without lymph node metastasis was conducted. Patients were divided into a positive group and a negative group based on the presence or absence of lymph node metastasis. Clinical and imaging data of the patients were collected, and the independent risk factors for lymph node metastasis in resectable lung adenocarcinoma were analyzed using univariate and multivariate logistic regression. A combined spatial location-clinical-imaging feature prediction model for lymph node metastasis was established and compared with the traditional lymph node metastasis prediction model that does not include spatial location features. Results A total of 611 patients were included, with 333 in the positive group, including 172 males and 161 females, with an average age of (58.9±9.7) years; and 278 in the negative group, including 127 males and 151 females, with an average age of (60.1±11.4) years. Univariate and multivariate logistic regression analyses showed that the spatial relationship of the lesion to the lung hilum, nodule type, pleural changes, and serum carcinoembryonic antigen (CEA) levels were independent risk factors for lymph node metastasis. Based on this, the combined spatial location-clinical-imaging feature prediction model had a sensitivity of 91.67%, specificity of 74.05%, accuracy of 87.88%, and area under the curve (AUC) of 0.885. The traditional lymph node metastasis prediction model, which did not include spatial location features, had a sensitivity of 76.40%, specificity of 72.10%, accuracy of 53.86%, and AUC of 0.827. The difference in AUC between the two prediction methods was statistically significant (P=0.026). Compared with the traditional prediction model, the predictive performance of the combined spatial location-clinical-imaging feature prediction model was significantly improved. Conclusion In patients with resectable lung adenocarcinoma, those with central/inner spatial location, solid density, pleural changes with wide base depression, and elevated serum CEA levels have a higher risk of lymph node metastasis.

The patient was a girl, aged 10 years, who was admitted due to fever for 5 days and pancytopenia in peripheral blood for 2 days. Bone marrow examination showed the presence of phagocytic activity, and peripheral blood tests showed pancytopenia, an increase in ferritin, a reduction in fibrinogen, increases in triglyceride and sCD25, and a reduction in natural killer cell activity, which led to the diagnosis of hemophagocytic lymphohistiocytosis (HLH). On the day of admission, the child developed convulsions and rapidly progressed to refractory status epilepticus, which was consistent with the manifestations of febrile infection-related epilepsy syndrome. HLH was controlled after active immunotherapy, with the sequela of refractory epilepsy, and her cognitive function was essentially within normal limits. This article reports the condition of febrile infection-related epilepsy syndrome caused by HLH for the first time in China, in order to improve the awareness of this disease among clinicians.

OBJECTIVES: To evaluate the safety and efficacy of thiotepa (TT)-containing conditioning regimens for allogeneic hematopoietic stem cell transplantation (HSCT) in children with inborn errors of immunity (IEI). METHODS: Clinical data of 22 children with IEI who underwent HSCT were retrospectively reviewed. Survival after HSCT was estimated using the Kaplan-Meier method. RESULTS: Nine patients received a traditional conditioning regimen (fludarabine + busulfan + cyclophosphamide/etoposide) and underwent peripheral blood stem cell transplantation (PBSCT). Thirteen patients received a TT-containing modified conditioning regimen (TT + fludarabine + busulfan + cyclophosphamide), including seven PBSCT and six umbilical cord blood transplantation (UCBT) cases. Successful engraftment with complete donor chimerism was achieved in all patients. Acute graft-versus-host disease occurred in 12 patients (one with grade III and the remaining with grade I-II). Chronic graft-versus-host disease occurred in one patient. The incidence of EB viremia in UCBT patients was lower than that in PBSCT patients (P<0.05). Over a median follow-up of 36.0 months, one death occurred. The 3-year overall survival (OS) rate was 100% for the modified regimen and 88.9% ± 10.5% for the traditional regimen (P=0.229). When comparing transplantation types, the 3-year OS rates were 100% for UCBT and 93.8% ± 6.1% for PBSCT (P>0.05), and the 3-year event-free survival rates were 100% and 87.1% ± 8.6%, respectively (P>0.05). CONCLUSIONS TT-containing conditioning for allogeneic HSCT in children with IEI is safe and effective. Both UCBT and PBSCT may achieve high success rates.
