Objective:To investigate the clinical effectiveness of Du Meridian moxibustion combined with brisk walking on negative symptoms, cognitive function, and social function in patients with stable schizophrenia, aiming to provide a feasible adjunctive treatment for clinical practice.Methods:A randomized controlled trial was conducted using convenience sampling to recruit 140 patients with stable schizophrenia hospitalized at the Affiliated Brain Hospital of Guangzhou Medical University from April 1, 2023, to March 31, 2024. Patients were randomly assigned to a control group, Du Meridian moxibustion group, brisk walking group, or combined group, with 35 patients in each group. The control group received standard care. On this basis, the Du Meridian moxibustion group received moxibustion on the Du Meridian, the brisk walking group participated in slow walking exercises, and the combined group received both interventions for 12 weeks. Assessments were conducted at baseline, at 6 and 12 weeks during the intervention, and at 12 weeks post-intervention using the Scale for the Assessment of Negative Symptoms, Mini-Mental State Examination, and Social Functioning Scale for Inpatient Psychiatric Patients.Results:A total of 134 patients completed the study: control group ( n = 34), Du Meridian moxibustion group ( n = 34), brisk walking group ( n = 35), and combined group ( n = 31). The combined group demonstrated significantly lower SANS scores at the 12th week of intervention (49.71 ± 4.66) and at 12 weeks post-intervention (53.45 ± 5.34) compared to the Du Meridian moxibustion group (54.91 ± 4.79) and (59.56 ± 5.84), the brisk walking group (56.69 ± 5.59) and (58.51 ± 5.42), control group (65.71 ± 4.95) and (66.21 ± 4.33), with statistically significant differences ( t values were 3.81-13.37, all P<0.05). Regarding cognitive function, the MMSE scores in the combined group at the 12th week of intervention (28.23 ± 1.28) and at 12 weeks post-intervention (27.35 ± 1.76) were higher than those in the Du Meridian moxibustion group (26.79 ± 1.85) and (25.59 ± 2.27) and the brisk walking group (25.88 ± 2.23) and (25.43 ± 1.84), control group (23.65 ± 2.17) and (22.32 ± 2.14), with statistically significant differences ( t values were - 10.28 to - 3.48, all P<0.001). For social function, the SSPI scores in the combined group at the 12th week of intervention (35.71 ± 3.63) and at 12 weeks post-intervention (32.58 ± 3.71) were also significantly higher than those in the Du Meridian moxibustion group (32.21 ± 3.91) and (28.47 ± 3.70) and the brisk walking group (31.83 ± 3.54) and (30.31 ± 3.59), control group (24.53 ± 4.12) and (24.15 ± 3.50) with statistically significant differences ( t values were - 11.56 to - 2.52, all P<0.05). Conclusions:The combination of Du Meridian moxibustion and brisk walking is an effective adjunctive intervention for patients with stable schizophrenia, as it significantly reduces negative symptoms, enhances cognitive function, and improves social functioning.

Objective:To construct a quality evaluation index system for perianal infection care in patients with hematologic neoplasms, aiming to establish a standardized approach for care.Methods:A quality evaluation index system for perianal infection management in patients with hematologic neoplasms was developed from January to June 2023 using Donabedian′s "Structure- Process- Outcome" approach, based on evidence- based literature study and expert conference discussions. An index system for evaluating the quality of perianal infection care in patients with hematologic neoplasms was established through expert consultation, and the weights for each indicator were derived using the analytic hierarchy process.Results:Two rounds of expert consultations were conducted, involving 27 experts aged 30 to 53 (38.85 ± 6.13) years, in which of them there were 1 male and 26 females. The positive coefficients of the experts in the two rounds of consultations were 100.00% (27/27) and 96.30% (26/27), respectively. The expert authority coefficients were 0.874 and 0.881, respectively, and the Kendall coordination coefficients were 0.234 and 0.219 (both P<0.05). The quality evaluation index system for perianal infection management in patients with hematologic neoplasms consisted of 3 main indicators (structural quality, process quality, outcome quality), 12 secondary indicators, and 48 tertiary indicators. Conclusions:The process of developing the quality assessment criteria for perianal infection care in patients with hematologic neoplasms is systematic and yields dependable results. The criteria cover a wide range of aspects and are specific, offering a valuable framework for assessing the quality of perianal infection care in patients with hematologic neoplasms.

Objective:To compare the efficacy and safety of LY01011,a recombinant anti-RANKL fully human monoclonal antibody injection,versus denosumab in the treatment of bone metastases from solid tumors.Methods:A randomized,double-blind,positive drug parallel-controlled,multicenter clinical trial was conducted.A total of 850 subjects were randomly assigned(1:1)to either the experimental group(424 subjects)or the control group(426 subjects).The experimental group received 13 doses of LY01011,while the control group received 3 doses of denosumab followed by 10 doses of LY01011.Results:The primary efficacy endpoint was the natural logarithmic change from baseline in urinary N-terminal telopeptide of type I collagen corrected by urinary creatinine(uNTX/uCr)at week 13.The change was-1.740(0.042 0)in the experimental group and-1.745(0.042 1)in the control group.The least-squares mean difference between groups was 0.005(90%CI:-0.088 to 0.097),indicating no statistically significant difference(P>0.05).Safety profiles,including treatment-emergent adverse events,laboratory tests,vital signs,physical examinations,and electrocardiograms,were comparable between groups(P>0.05).Conclusions:LY01011 demonstrated biosimilarity to denosumab,with favorable safety profile,tolerability,and potential for clinical application.

Objective To explore the effect of Xiongcan Yishen Formula on ferroptosis in testicular tissue of male rats with late-onset hypogonadism(LOH).Methods A total of 48 male Sprague-Dawley rats aged 6 months were randomly divided into model group,low-dose and high-dose Xiongcan Yishen Formula groups and propionate testosterone group,with 12 rats in each group.An additional 6 male Sprague-Dawley rats aged 8 weeks were set as the normal group.Except for the normal group,the rats were intraperitoneally injected with Cyclophosphamide at a dose of 20 mg/(kg·d)for 5 consecutive days to establish the LOH model,while the normal group received an equal volume of physiological saline for 5 days.The normal group and model group were given equal volumes of distilled water by gavage,while the low-dose and high-dose Xiongcan Yishen Formula groups were administered concentrated decoction at doses of 10.4 g and 41.6 g/kg/d respectively,and the propionate testosterone group received intramuscular injections of 5.21 mg/kg/d propionate testosterone,all for 28 consecutive days.ELISA was used to detect serum testosterone levels in rats,HE staining and transmission electron microscopy were used to observe the gross morphology of testicular tissue and the ultrastructure of Leydig cells,and RT-qPCR and Western blotting were used to detect the expression of ferroptosis-related genes and proteins in testicular tissue.Results The LOH model rats exhibited pathological changes such as atrophy of seminiferous tubules,structural disorder,and reduced spermatocytes in the lumen,as well as ultrastructural changes in Leydig cells including altered nuclear morphology,increased mitochondrial density,and reduced cristae.After intervention with Xiongcan Yishen Formula and propionate testosterone,the pathological changes in testis and the ultrastructure of Leydig cells were improved.Compared with the normal group,serum testosterone levels in the model group were significantly decreased(P＜0.05),the expression of ROS,ACSL4 mRNA and protein in testicular tissue was significantly increased,while the expression of FTH1,GPX4,and SLC7A11 mRNA and protein was significantly decreased(P＜0.05).Compared with the model group,ser-um testosterone levels in the low-dose and high-dose Xiongcan Yishen Formula groups and the propionate testosterone group were significantly increased(P＜0.05),and the expression of ROS,ACSL4 mRNA and protein was significantly decreased(P＜0.05);the high-dose Xiongcan Yishen Formula group showed significantly increased expression of FTH1,GPX4,and SLC7A11 mRNA and protein(P＜0.05).Conclusion Ferroptosis in testicular tissue is increased in LOH rats,and Xiongcan Yishen For-mula can elevate serum testosterone levels and improve pathological changes and ultrastructure in testicular tissue of LOH rats,possibly related to the inhibition of ferroptosis in testicular tissue of LOH rats.

Objective To explore the clinical value of high frequency ultrasound combined with dermoscopy in preoperative evaluation of cutaneous malignant tumors.Methods A total of 323 patients with suspected cutaneous malignant tumors were selected from Jinhua Municipal Central Hospital from January 2022 to December 2023.The clinical value of high frequency ultrasound,dermoscopy and their combined examination in preoperative diagnosis of cutaneous malignant tumors were analyzed and compared.Results A total of 323 patients with suspected cutaneous malignant tumors,223 patients with confirmed cutaneous malignant tumors by skin pathology,234 skin lesions,and 100 patients with benign skin tumors were included.141 skin lesions were detected by dermoscopy,195 skin lesions by high frequency ultrasound,and 213 skin lesions by the combination of dermoscopy and high frequency ultrasound.The sensitivity,specificity and accuracy of high frequency ultrasound combined with dermoscopy in diagnosis of cutaneous malignant tumors were 87.6％,92.0％and 88.9％,respectively,which was higher than that of single high frequency ultrasound and single dermoscopy.The diagnosis results of dermoscopy combined with high frequency ultrasound were in good agreement with the pathological results(kappa=0.75).Conclusion Dermoscopy and high frequency ultrasound are convenient,non-invasive and sensitive imaging methods for skin detection.They can balance resolution and depth of detection,reveal morphological information of tumors,and predict the risk of tumor recurrence.

Sepsis is a systemic inflammatory response triggered by infection and often leads to acute kidney injury(AKI).The pathogenesis of sepsis-associated AKI is complex,involving multiple factors such as renal ischemia,inflammation and oxidative stress.In recent years,pyroptosis,a pro-inflammatory form of programmed cell death,has gradually attracted the attention of researchers.Pyroptosis is activated by inflammasomes(e.g.,the NOD-like receptor pyrin domain-related protein 3 inflammasome,NLRP3 inflammasome),accompanied by Gas-dermin D(GSDMD)-mediated formation of cell membrane pores and release of cellular contents,which leads to exacerbation of local and systemic inflammatory responses.The mechanism of pyroptosis in sepsis-associated AKI has not been fully elucidated,but AKI is directly involved in the process of renal functional impairment by indu-cing the death of renal tubular epithelial cells and exacerbating the local inflammatory response.Blockade of key molecules in the pyroptosis pathway,such as GSDMD or NLRP3 inflammasome,can significantly alleviate renal injury,suggesting that the pyroptosis pathway may be a potential therapeutic target for sepsis-associated AKI.This review summarizes the recent research progress on pyroptosis in sepsis-associated AKI,and discuss its cen-tral role in the pathogenesis,particularly focusing on the inflammasome and GSDMD pathways.Additionally,this paper analyzes the potential of focal death inhibition as a therapeutic strategy and proposes future research direc-tions with the expectation of providing references for the treatment of sepsis-related AKI.

Objective:To evaluate the accuracy of p53 immunohistochemistry for predicting the mutational status of TP53 in gliomas.Methods:A retrospective study was conducted on 242 diffuse gliomas diagnosed at the Department of Pathology, the First Affiliated Hospital of Fujian Medical University, Fuzhou, China from June 2022 to March 2023. All cases underwent next-generation sequencing (NGS) and p53 immunohistochemical staining. The best threshold in the percentage of p53 immunohistochemical expression was assessed as an alternative to testing for TP53 mutation.Results:Among the 242 diffuse gliomas (WHO grade 2-4), 94 cases had a TP53 mutation. The p53 immunohistochemistry results revealed a significantly increased probability of TP53 mutation when the p53 immunohistochemical positivity rate (based on strongly positive cell count) was ≥20% ( P<0.05). The sensitivity and specificity of p53 immunohistochemistry for predicting TP53 gene mutations were 75.6% and 90.4%, respectively. When p53 immunohistochemical stain was totally negative, the probability of TP53 mutation increased significantly, and the mutation ratio of TP53 gene was 6/17 in all negative cases. Conclusions:When the percentage of p53 positive cells (based on strongly positive cell count) in glioma is ≥20%, p53 immunohistochemistry can be used as a reliable alternative method for TP53 mutation detection. When p53 immunohistochemistry is completely negative, the mutation rate of TP53 gene is higher, and further gene sequencing is recommended to determine the mutation status.

Objective To elucidate the regulatory effects of titanium surface modification on the immune function of immature dendritic cells(imDCs),different crystalline nanomorphologies were constructed on titanium surface to investigate the mechanobiological response of imDCs to nanomorphologies with different crystalline phases.Methods Nanomorphologies with different crystalline phases were constructed on the titanium surface by anodic oxidation and calcination.The changes of the cytoskeleton F-actin,cell adhesion and morphology of imDCs cultured on nanomorphologies with different crystalline phases were observed by fluorescence staining.The relative gene expression of adhesion molecules was detected by quantitative real-time PCR.The migration behaviors of imDCs were observed using real-time live-cell imaging,and the membrane fluidity was detected by fluorescence polarization.Results Nanomorphologies with different crystalline phases,namely amorphous phase,anatase and rutile,were obtained on the titanium surface by anodic oxidation and calcination.The cytoskeleton of imDCs on nanomorphologies with different crystalline phases was remodeled.The spreading area of cells on anatase crystalline phase was relatively small,which was(353.3±148.5)μm2.The number of adherent cells was the largest,which was 587±132.The expression of adhesion molecules such as CD11a,integrin β2,ICAM1,and VCAM1 were also increased in cells which cultured on anatase crystalline phase.The imDCs cultured on anatase crystalline phase were equipped with strong migration ability.The accumulative migration distance was(383.6±177.7)μm,and the Euclidean migration distance was(51.82±50.13)μm.The membrane fluidity was relatively weak,and the fluorescence polarization was 0.348 5±0.041 8.Conclusions imDCs can respond to nanomorphologies with different crystalline phases on the titanium surface and exhibit different biomechanical behaviors.The results might provide a theoretical basis for the design of titanium biomaterials with immunomodulatory functions.
