Renal ischemia-reperfusion injury （RIRI） is a major cause of acute kidney injury during kidney transplantation and peri-operative settings， and there is still a lack of safe and effective targeted preventive and therapeutic drugs in clinical practice. Specifically， xanthohumol， luteolin， dracorhodin C， naringin， senkyunolide Ⅰ， verbascoside， and shikonin enhance antioxidant defenses， and inhibit lipid peroxidation and ferroptosis via the nuclear factor-erythroid 2-related factor 2/heme oxygenase-1 pathway. Apigenin， nobiletin， tanshinone Ⅱ A ， and salidroside activate the phosphatidylinositol 3-kinase/protein kinase B pathway to inhibit mitochondria- dependent apoptosis and facilitate renal repair. Quercetin， methyleugenol， cyanidin-3-glucoside， and platycodin D promote autophagy and improve mitochondrial homeostasis through the adenosine monophosphate-activated protein kinase（AMPK）/mTOR or AMPK/phosphatase and tensin homolog-induced kinase 1/Parkin pathways. In addition， hesperidin， curcumin， ganoderic acid， pulsatilla saponin B4， capsaicin， and diosgenin mitigate inflammatory responses and decrease renal tubular injury markers by inhibiting the Toll-like receptor 4/nuclear factor κB， high mobility group box 1， Janus kinase/signal transducer and activator of transcription pathways， thereby exerting multi-target， multi-stage renoprotective effects.

ObjectiveTo find out whether there is any difference in the monitoring results of mosq-ovitraps placed in different orientations in multi-storey residential areas, so as to provide a scientific basis for routine and emergency monitoring of Aedes albopictus with mosq-ovitraps in residential areas. MethodsFrom July 6th to October 26th 2023, one mosquito ovitrap was set up in each of the 4 orientations of east, south, west and north around the buildings in a multi-storey residential area in Jinhui Town, Fengxian District, Shanghai. Data was collected and recorded 72 hours after placement. The chi-square test was used to compare the mosquito ovitrap indices (MOIs) of two independent samples, and the Kruskal⁃Wallis H test was used to compare the MOIs of multiple independent samples. ResultsAfter 16 weeks of surveillance, 997 mosquito ovitraps were recovered, of which 211 were positive, with the mosquito ovitrap index (MOI) of 21.16% and the Aedes albopictus density index of 1.03 mosquitoes·ovitrap^-1. The MOIs were higher in September (24.22%) and October (23.96%), and the MOIs in the west, south and north within the two months were all above 20.00%. From July to October, the MOIs in the east, west, south and north were 20.70%, 22.20%, 25.50% and 16.20%, respectively, and the difference in MOIs among the 4 orientations was not statistically significant (χ²=6.647, P=0.084). Stratified analysis by month showed that in August, the south side of the multi-storey residential areas had the highest MOI (31.30%), the north side had the lowest MOI (1.30%), and there was a statistically significant difference in MOI in the east, west, south and north (χ²=25.986, P<0.001). In October, the MOI in the west was the highest (33.30%) and the MOI in the east was the lowest (6.30%), the difference in MOIs of the 4 orientations was statistically significant (χ²=12.007, P=0.007). The MOIs in the south side of the building in the outskirts of the residential area from the 1st week in July to the 4th week in October was lower (19.20%) than that in the south side of the inner building (31.70%), and the difference in MOI was statistically significant (χ²=5.118, P=0.024). ConclusionThe study of MOI in different orientations in a multi-storey residential area is a preliminary exploration based on field work, and the results show that there is a difference in MOIs in different orientations during the peak breeding period of mosquitoes. Further indicators such as temperature, humidity and wind speed in different orientations can be collected to explore the influencing factors of MOIs.

Objective:To investigate the clinical significance and inducing factors of abnormal intraoperative neurophysiological monitoring (IONM) signals during surgery for cervical degenerative diseases.Methods:A retrospective analysis was performed on 586 patients who underwent cervical degenerative disease surgery with IONM at the Department of Orthopedics, The First Affiliated Hospital of Soochow University, from April 2015 to April 2024. Surgical approaches included 380 anterior spinal canal decompression and fusion procedures, 154 posterior spinal canal decompression and fusion procedures (including single-door laminoplasty, total laminectomy, and hemilaminectomy), and 52 combined anterior-posterior surgeries. The multimodal IONM protocol employed transcranial electrical stimulation motor evoked potentials (TES-MEP) and cortical somatosensory evoked potentials (CSEP), combined with electromyography (EMG). Bilateral deltoid muscles, thenar/hypothenar muscles and abductor hallucis muscles were monitored in all patients. Intraoperative MEP, SEP, and EMG results were recorded to analyze the causes of abnormal signals, intraoperative response strategies, and postoperative neurological function and outcomes. Fourfold table chi-square tests were used to analyze factors possibly associated with IONM alerts.Results:Among the 586 cervical surgeries, 17 cases (2.9%) exhibited abnormal IONM signals. These included 4 cases of anterior cervical discectomy and fusion (ACDF), 4 cases of anterior cervical corpectomy and fusion (ACCF), and 2 cases of combined anterior-posterior surgeries for cervical spondylotic myelopathy; and 5 posterior surgeries and 2 anterior ACCF procedures for ossification of the posterior longitudinal ligament (OPLL). The rate of abnormal IONM signals was significantly higher in patients with maximum spinal cord compression (MSCC)>60% (5.8%, 12/208) than in those with MSCC≤60% (χ 2=9.417, P=0.002); in patients with intraoperative hypotension during posterior surgery (mean arterial pressure reduction>20% from baseline, cumulative duration>20 min), the abnormal IONM rate was 22.2% (6/27), which was significantly higher than that in patients without intraoperative hypotension (χ 2=33.542, P<0.001); in patients who underwent calcified tissue removal during anterior surgery, the abnormal IONM rate was 9.3% (5/54), which was significantly higher than that in patients without calcified tissue removal (χ 2=13.162, P=0.003). Thus, MSCC>60%, intraoperative hypotension during posterior surgery, and calcified tissue removal during anterior surgery may be inducing factors for abnormal IONM signals. Among the 17 patients with monitoring abnormalities, 8 cases showed no significant improvement after corresponding intraoperative treatments, and 7 of these 8 cases experienced varying degrees of muscle strength decline and sensory numbness immediately after surgery; 9 cases showed partial or complete recovery of signals, among which 8 cases had no new-onset neurological impairment after surgery, and 1 case developed unilateral upper limb grip strength decline. IONM demonstrated a sensitivity of 0.8750 and specificity of 0.8889. Conclusions:Multimodal IONM can detect electrophysiological abnormalities of spinal cord nerve function during cervical degenerative disease surgery, providing real-time warning of potential nerve damage during the operation. The proportion of abnormal IONM signals is relatively high in cases with MSCC>60%, intraoperative hypotension during posterior cervical surgery, or calcified tissue removal during anterior cervical surgery.

OBJECTIVE: To compare the effects of double-channel core decompression (CD) combined with medullary cavity irrigation with those of simple CD on progression of collapse and clinical outcomes in non-traumatic osteonecrosis of the femoral head (ONFH). METHODS: A retrospective analysis was conducted on the clinical data of 19 patients (30 hips) with non-traumatic ONFH who underwent double-channel CD combined with medullary cavity irrigation and admitted between January 2024 and October 2024 (CD+irrigation group). According to a 1: 2 ratio, 54 patients (60 hips) who underwent simple CD and were matched in terms of age, gender, and body mass index (BMI) were included as the control (CD group). There was no significant difference in baseline data such as age, gender, BMI, affected side, ONFH type, preoperative Association Research Circulation Osseous (ARCO) stage, bone marrow edema stage, visual analogue scale (VAS) score for pain, and Harris score between the two groups ( P>0.05). The postoperative discharge time and occurrence of complications were recorded for both groups. The VAS scores before operation and at discharge after operation were compared, and the differences between pre- and post-operation (change values) were calculated for intergroup comparison. The Harris scores before operation and at discharge and 3 months after operation were also compared. During follow-up, X-ray film, CT, and MRI were performed for reexamination. The ARCO stage and bone marrow edema stage were evaluated at 3 months after operation and compared with those before operation to determine whether there was radiological progression or relief. RESULTS: All incisions in both groups healed by first intention after operation, with no infection, femoral neck fracture, or other operation-related complications. All patients were followed up, and the follow-up time of the CD+irrigation group was (146.8±27.7) days, and that of the CD group was (164.3±48.2) days; there was no significant difference between the two groups ( t=1.840, P=0.069). There was no significant difference in the length of hospital stay between the two groups ( P>0.05). At discharge after operation, the VAS score of the CD+irrigation group was significantly lower than that of the CD group ( P<0.05), and the change value was significantly higher than that of the CD group ( P<0.05). The Harris scores at discharge and 3 months after operation in the CD+irrigation group were significantly higher than those in the CD group ( P<0.05). The Harris score gradually increased with time, and the differences between different time points were significant ( P<0.05). Radiological reexamination showed that there was no significant difference in the ARCO stage and the incidence of radiological progression between the two groups at 3 months after operation ( P>0.05); however, the bone marrow edema stage and the degree of bone marrow edema relief in the CD+irrigation group were better than those in the CD group, with significant differences ( P<0.05). CONCLUSION Double-channel CD combined with medullary cavity irrigation can significantly alleviate hip joint pain and improve joint function in patients with non-traumatic ONFH, reduce the degree of bone marrow edema in the femoral head, and delay the progression of ONFH.

Objective:To investigate the clinicopathological characteristics and diagnostic criteria of cutaneous melanocytic tumor with CRTC1::TRIM11 fusion (CMTCT), and to improve understanding of this entity.Methods:The clinical features, histology, immunohistochemistry (IHC) and molecular characteristics of 3 CMTCT cases were analyzed, supplemented by a literature review.Results:All patients were female, aged 53, 46 and 46 years, respectively. Grossly, the lesions presented as dermal/subcutaneous nodules protruding from the skin surface. Histologically, tumor cells were arranged in nested and fascicular patterns separated by delicate fibrous septa. Tumor cell infiltration was observed in the epidermis of case 1, but not in that of cases 2 and 3. Tumor cells exhibited epithelioid, spindle-shaped, or oval morphology, with eosinophilic or pale cytoplasm and mild to moderate nuclear atypia. Tumor mitotic figure was <5/10 HPF. Scant melanin pigment was observed in case 2. IHC demonstrated diffuse and strong positivity for SOX-10, S-100 protein and MITF. HMB45 was negative in two cases (case 1 and case 3) and focally positive in case 2; Melan A was negative in two cases (case 1 and case 3) and partially positive in case 2. The Ki-67 proliferation index was approximately 5%-8%. Molecular analysis revealed CRTC1::TRIM11 fusion in three cases via RNA sequencing, and CRTC1 rearrangement in two cases (case 1 and case 3) via fluorescence in situ hybridization.Conclusions:CMTCT shares histological and immunophenotypic features with melanoma and clear cell sarcoma but is defined by the presence of CRTC1::TRIM11 fusion, necessitating molecular confirmation for definitive diagnosis. Complete excision with clear margins is recommended. While most of the CMTCTs exhibit indolent biological behaviors, rare cases may recur locally or metastasize, warranting close follow-up.

Objective:To identify the main components of Huanglian Jiedu Decoction(HLJDD)using ultra-high-performance liquid chromatography-quadrupole-time of flight-mass spectrometry(UPLC-Q-TOF-MS),and to explore the potential mechanism of action of HLJDD in the treatment of gouty arthritis(GA)using network pharmacology and molecular docking methods.Methods:We identi-fied the chemical components of HLJDD by combining UPLC-Q-TOF-MS data acquired in both positive and negative ion modes with reference standards,relevant literature,and database searches.We analyzed the potential therapeutic mechanism of HLJDD for GA by using network pharmacology to determine the intersection targets between the active ingredients of HLJDD and GA for further enrich-ment analysis and visual network mapping.The binding affinity of the active ingredients with the intersection targets was validated through molecular docking.Results:A total of 47 components were identified by UPLC-Q-TOF-MS;54 key components of HLJDD for GA treatment and 37 intersection targets were determined by net-work pharmacology;and the top 10 key targets by Degree value were obtained by protein-protein interaction analysis.The Gene On-tology functional enrichment analysis revealed 20 biological pro-cesses,7 cellular components,and 8 molecular functions.The Kyoto Encyclopedia of Genes and Genomes pathway enrichment analysis demonstrated 96 GA-related intervention pathways,in which inflammatory signaling pathways such as interleukin-17(IL-17)and tu-mor necrosis factor(TNF)were involved.Molecular docking verified that the key components of HLJDD had high binding affinity with the core targets.Conclusion:The identified key components in HLJDD,such as phellodendrine,coptisine,wogonin,and β-sitosterol,may alleviate GA by regulating multiple core targets in the IL-17 and TNF pathways,such as PTSG2,which provides a theoretical ba-sis for future investigation into the mechanism of action of HLJDD.

Objective To investigate the clinicopathological and prognostic characteristics of intestinal inflammatory myofibroblastic tumours(IMT)in middle-aged and elderly patients.Methods The clinical,pathologi-cal morphology,immunophenotype and follow-up results of 5 cases of intestinal IMT in middle-aged and elderly patients were retrospectively analyzed.Results 4 cases of IMT occurred in the right half colon and 1 in the ileum.Most patients(3/5)had a history of intestinal injury,starting the digestive tract symptoms and increased leukocytes.The tumor tissue was composed of fusiform myofibroblasts and fibroblasts arranged in storiform pattern,with an infiltrative growth pattern,accompanied by a large number of lymphocytes and plasma cells infiltration,collagen formation and myxedema.One case was atypically large and deformed.Immunophenotype:vimentin(5cases),SMA(5 cases),desmin(3 cases),ALK(3 cases),CK(2 cases)were positive.Caldesmon,CD34,β-catenin,MC,CD117,DOG1,S-100,BCL-2,CD99,CD68 were negative,and Ki-67 proliferation index was 1.28%to 10.01%.All the 5 cases underwent complete tumor resection and were followed up for 48.5 to 133 months.Among them,1 patient aged 83 was considered to have tumor recurrence 27 months after surgery.The other patient survived 122 months without tumor and died of other causes.All the others survived without tumor and were in good condition.Conclusion(1)Intestinal IMT in the middle-aged and elderly people in this group was more common in the right half colon,and most of them had a history of intestinal injury,first gastrointestinal symptoms and elevated white blood cells;(2)Vimentin and SMA were positive at the same time,and ALK was more positive;(3)4/5 patients had good surgical resection,and 1/5 patients could relapse 2～3 years after surgery;old age,ALK-positive,Ki67 up to 10%,atypia may be an important risk factor for intestinal IMT recurrence in the elderly,of which ALK-positive patients may have a recurrence risk of 1/3.

Objective:To investigate the association of urinary cadmium level with body mass index (BMI) and body circumferences among the older adults over 65 years old in 9 longevity areas of China.Methods:Subjects were older adults over 65 years old from the Healthy Aging and Biomarkers Cohort Study (HABCS) between 2017 and 2018 conducted in 9 longevity areas in China. A total of 1 968 older adults were included in this study. Information including socio-demographic characteristics, lifestyles, diet intake, and health status was collected by using questionnaires and physical examinations. Urine samples were collected to detect urinary cadmium and creatinine levels. Body circumferences included waist circumference, hip circumference and calf circumference. Subjects were divided into three groups (low:<0.77 μg/g·creatinine, middle:0.77-1.69 μg/g·creatinine, high:≥1.69 μg/g·creatinine) by tertiles of creatinine-adjusted urinary cadmium concentration. Multiple linear regression models were used to analyze the association of creatinine-adjusted urinary cadmium level with BMI and body circumferences. The dose-response relationship of creatinine-adjusted urinary cadmium concentration with BMI and body circumferences was analyzed by using restrictive cubic splines fitting multiple linear regression model.Results:The mean age of subjects was (83.34±11.14) years old. The median (Q1, Q3) concentration of creatinine-adjusted urinary cadmium was 1.13 (0.63, 2.09) μg/g·creatinine, and the BMI was (22.70±3.82) kg/m 2. The mean values of waist circumference, hip circumference, and calf circumference were (85.42±10.68) cm, (92.67±8.90) cm, and (31.08±4.76) cm, respectively. After controlling confounding factors, the results of the multiple linear regression model showed that for each increment of 1 μg/g·creatinine in creatinine-adjusted urinary cadmium, the change of BMI, waist circumference, hip circumference, and calf circumference in the high-level group was -0.28 (-0.37, -0.19) kg/m 2, -0.74 (-0.96, -0.52) cm, -0.78 (-0.96, -0.61) cm, and -0.20 (-0.30, -0.11) cm, respectively. The restrictive cubic splines curve showed a negative nonlinear association of creatinine-adjusted urinary cadmium with BMI ( Pnonlinear<0.001) and negative linear associations of creatinine-adjusted urinary cadmium with waist circumference ( Plinear<0.001), hip circumference ( Plinear<0.001), and calf circumference ( Plinear<0.001). Conclusion:Urinary cadmium level is significantly associated with decreased BMI, waist circumference, hip circumference and calf circumference among older adults over 65 years old in 9 longevity areas of China.
