Objective:
To evaluate the diagnostic potential of fluid suppression (FS) techniques combined with amide proton transferweighted imaging (APTw) for assessment of isocitrate dehydrogenase (IDH) mutation status, glioma subtypes, and tumor proliferation.
Materials and Methods:
This retrospective study included 117 patients with adult-type diffuse gliomas. Conventional APTw, FSAPTw, and spillover-corrected FS-APTw (SCFS-APTw) metrics were calculated from 3T MRI data in tumor parenchyma, necrotic or cystic regions, and contralateral normal-appearing white matter. APTw signals were compared across the three techniques within each region, between IDH-mutant and IDH-wildtype gliomas, and among astrocytoma, oligodendroglioma, and glioblastoma subtypes. Diagnostic performance for distinguishing IDH mutation status and glioma subtypes was assessed using receiver operating characteristic (ROC) analysis. Correlations between APTw metrics and Ki-67 expression were also analyzed.
Results:
Both FS-APTw and SCFS-APTw significantly reduced signal intensity in tumor parenchyma and necrotic or cystic regions, with SCFS-APTw demonstrating a stronger suppression effect. IDH-wildtype gliomas showed significantly higher APTw metrics than IDH-mutant gliomas (all P < 0.001). Glioblastomas exhibited significantly higher metrics than oligodendrogliomas (all corrected P ≤ 0.015) and astrocytomas (all corrected P < 0.001). SCFS-APTw achieved the highest area under the ROC curve (AUC) of 0.846 for identification of IDH mutation status. For differentiation between astrocytomas and glioblastomas, the 90th percentile of APTw yielded the highest AUC (0.860), followed by SCFS-APTw (0.849). For discrimination between oligodendrogliomas and glioblastomas, the highest AUC (0.832) was obtained using the 90th percentile of SCFS-APTw. None of these metrics successfully differentiated oligodendrogliomas from astrocytomas. SCFS-APTw demonstrated the strongest correlation with Ki-67 expression (r = 0.451).
Conclusion
FS techniques effectively reduce elevated APTw signals originating from fluid compartments. Their combination with APTw imaging enables evaluation of IDH mutation status, glioma subtypes, and tumor proliferative activity in adulttype diffuse gliomas.

Renal hilar tumors pose significant surgical challenges due to their proximity to major renal vessels and the collecting system. In robot-assisted partial nephrectomy, although both anterior and posterior lip tumors are considered renal hilar tumors, their operative difficulty and complication profiles differ markedly owing to distinct anatomical relationships and vascular adjacency. Anterior lip tumors, often involving tributaries of the renal vein, carry a relatively higher risk of intraoperative and postoperative bleeding. In contrast, posterior lip tumors, closer to the renal artery, are more likely to prolong warm ischemia time, thereby increasing the risk of postoperative renal impairment. Regarding urine leakage, although anterior lip tumors are theoretically closer to the collecting system and may pose a slightly elevated risk, precision reconstruction strategies—such as lip reconstruction based on sinus space anatomy—can effectively mitigate this risk. However, the specific difference in urine leakage risk between anterior and posterior lip tumors warrants further investigation. Both anterior and posterior lip tumors of the kidney can achieve low positive surgical margin rates in experienced centers. Complication risks are affected by multiple factors, including tumor anatomical complexity, warm ischemia time, and surgeon experience. Notably, R.E.N.A.L. score>8 is associated with significantly increased complication risks. Preoperative meticulous imaging evaluation, selection of an appropriate surgical approach based on tumor location, controlled warm ischemia time, and application of delicate suturing and reconstruction techniques are essential strategies to reduce complications.

Objective To investigate the entrance surface dose (ESD) of dental radiological diagnosis and treatment devices in Nanping City of Fujian Province, China, assess the radiation risk differences between cone beam computed tomography (CBCT) and conventional oral panoramic tomography (COPT), and compare the output dose levels between domestic and imported devices and between public and private medical institutions, and to provide evidence for optimizing radiation protection strategies. Methods A cross-sectional survey was conducted on 38 extraoral dental X-ray devices from 38 dental institutions in Nanping City. Measurements of ESD for different exposure types (adult/child COPT and CBCT) were performed using an adult head-and-neck phantom and thermoluminescent dosimeters. A statistical analysis (Mann-Whitney U test) was applied to compare dose differences by device type and institution type. Results The median tooth-region doses for adult/child CBCT (8.97/6.80 mGy) were significantly higher than those of adult/child COPT (0.33/0.24 mGy), with the 75th percentile values (12.44/8.18 mGy) exceeding the national guideline level of 7 mGy. Domestically manufactured devices demonstrated higher median doses and greater dose variability compared to imported devices (P < 0.05). Private institutions exhibited inferior dose control stability relative to public institutions (P < 0.001). CBCT delivered substantially higher radiation exposure to the thyroid and ocular lenses, with child lens dose reaching 5.9 times that of COPT. Conclusion Dental CBCT radiation doses in Nanping City exceed the guideline level. Enhanced protection for sensitive organs, restriction of unnecessary pediatric examinations, technological upgrades for domestic devices, and strengthened regulation and operational standardization of private institutions are critical to achieve precise radiation protection and improved medical quality.

ObjectiveTo investigate the effect of Niuhuang Qingxinwan (NHQXW) in improving intracerebral hemorrhage (ICH) with Tanre Fushi (phlegm-heat and fu-organ excess) syndrome by maintaining blood-brain barrier (BBB) integrity, and to explore its potential mechanism. MethodsMale mice were administered with 15% autologous feces for 3 consecutive days to simulate spontaneous Tanre Fushi syndrome, followed by surgical induction of collagenase-induced ICH on the fourth day. Mice were randomly assigned to seven groups: Sham, Sham+NHQXW-H, collagenase, collagenase+feces, and NHQXW intervention groups at low (NHQXW-L, 0.225 g·kg-1), medium (NHQXW-M, 0.45 g·kg-1), and high (NHQXW-H, 0.9 g·kg-1) doses. Treatments were administered for 3 days after surgery. NHQXW effects on Tanre Fushi syndrome were assessed via fecal water content and small intestinal carbon propulsion rate. Protective effects of NHQXW against ICH with Tanre Fushi syndrome were evaluated by measuring hematoma volume, neurological deficits, and brain water content. BBB integrity was further assessed using Evans blue staining, hematoxylin-eosin (HE) staining, immunofluorescence, and Western blot for Claudin-5, plasmalemma vesicle-associated protein (PLVAP), matrix metalloproteinase (MMP)-2, and MMP-9. The potential mechanism of NHQXW was investigated by detecting protein expression of protein kinase B (Akt), extracellular signal-regulated kinase 1/2 (ERK1/2), signal transducer and activator of transcription 3 (STAT3), Yes-associated protein (YAP), and their phosphorylated forms. ResultsCompared with the collagenase+feces group, NHQXW-M and NHQXW-H significantly reduced fecal water content (P<0.05, P<0.01) and intestinal propulsion rate (P<0.01), alleviated neurological deficits (P<0.01), decreased hematoma volume (P<0.01) and Evans blue extravasation (P<0.01), increased Claudin-5 protein expression (P<0.05, P<0.01) and fluorescence intensity (P<0.01), and decreased PLVAP protein expression (P<0.01) and fluorescence intensity (P<0.05, P<0.01), as well as MMP-2 (P<0.05, P<0.01) and MMP-9 (P<0.01) expression. NHQXW-H downregulated p-Akt (P<0.05), p-ERK1/2 (P<0.05), p-STAT3 (P<0.01), and p-YAP (P<0.05), with the most significant effect observed on STAT3 phosphorylation. ConclusionNHQXW effectively alleviates neurological deficits and BBB injury in ICH mice with Tanre Fushi syndrome, primarily by inhibiting STAT3 activation.

ObjectiveTo construct a family-centered care model for children with tuberculosis based on the double ABC-X model, and to evaluate its clinical effects. MethodsFrom December 2022 to October 2023, 64 newly admitted children with tuberculosis who met the criteria and their caregivers were recruited from the tuberculosis department of Shanghai Public Health Clinical Center were randomly divided into an experimental group (32 cases) and a control group (32 cases).The control group was given a conventional health care, while the experimental group was given a family-centered health care intervention based on the double ABC-X model, in which a multidisciplinary care team provided personalized information and emotional support for the caregivers and their children. Medication adherence of the children, caregiver’s teading burden, and disease management competence were compared between the 2 groups. ResultsA total of 29 cases in the experimental group and 27 cases in the control group completed the intervention. At 12 weeks of intervention, the medication adherence score (7.72±0.45 vs 7.41±0.50, P<0.05) and disease management competence score (36.97±7.85 vs 31.56±7.30, P<0.05) were higher in the experimental group than that in the control group while the caregiving burden score (31.79±13.40 vs 40.04±9.01, P<0.05) and difficulty of disease management score (30.41±12.41 vs 38.56±9.48, P<0.05) were lower than that in the control group. At 24 weeks of intervention, the medication adherence score (7.34±0.97 vs 6.70±1.14, P<0.05) and disease management competence score (42.07±6.93 vs 35.63±7.32, P<0.05) were higher in the experimental group than that in the control group as well, but the caregiving burden score (31.62±11.72 vs 39.63±10.17, P<0.05) and difficulty of disease management score (30.59±10.87 vs 37.81±9.32, P<0.05) were lower than that in the control group. ConclusionFamily-centered care based on the double ABC-X model can effectively promote medication adherence among children with tuberculosis, reduce caregivers’ care burden and disease management difficulties, and improve caregiver’s disease management competence.

OBJECTIVE:
To compare the clinical efficacy of electroacupuncture (EA) at neuro-arterial stimulation points with topical western medication in treating post-stroke shoulder-hand syndrome (SHS).
METHODS:
A total of 72 patients with post-stroke SHS were randomly assigned to an observation group (n=36, 2 cases dropped out) and a control group (n=36, 3 cases dropped out). Both groups received standard neurological treatment, comprehensive rehabilitation, and physical therapy. The observation group received EA at neuro-arterial stimulation points, including the ipsilateral stellate ganglion point, vagus nerve trunk and auricular branch (left side), and stimulation points of the radial and ulnar arteries, radial nerve, ulnar nerve, and median nerve, once daily for 4 weeks. The control group was treated with topical diclofenac diethylamine emulgel, and mucopolysaccharide polysulfate cream was added for patients with pronounced early-stage edema, twice a day for 4 weeks. The VAS pain score and hand edema volume were recorded before treatment, at 2 and 4 weeks during treatment, and 2 weeks after treatment completion (follow-up). Musculoskeletal ultrasound was used to measure the thickness of the dorsal hand and middle finger skin on the affected side before and after 4 weeks of treatment.
RESULTS:
Compared before treatment, the VAS pain scores and edema volume of the affected hand in both groups were decreased at week 2, week 4, and follow-up (P<0.05). At week 4, both groups showed lower VAS pain scores and edema volume than those at week 2 (P<0.05); during follow-up, both VAS pain scores and edema volume were further reduced compared to those at week 4 (P<0.05). At week 2, week 4, and follow-up, the VAS scores and edema volume of the affected hand in the observation group were lower than those in the control group (P<0.05). Compared before treatment, the dorsal hand skin thickness and middle finger skin thickness on the affected side were decreased in both groups after 4 weeks of treatment (P<0.05). Compared with the control group, the observation group showed thinner dorsal hand and middle finger skin thickness after 4 weeks of treatment (P<0.05).
CONCLUSION
EA at neuro-arterial stimulation points effectively alleviates pain and edema in patients with post-stroke SHS, and demonstrates superior efficacy compared to topical western medication.

To realize speed regulation and safe distance maintenance of mobile robots based on obstacle detection in dynamic healthcare scenarios,a novel real-time obstacle segmentation and safe operation framework for healthcare robots is proposed.A tightly-coupled approach utilizing wheel encoders and monocular RGB images to calculate the robot's linear velocity is adopted.Concurrently,a healthcare scenario end-to-end obstacle segmentation network(HS-EOSN)model is established for precise obstacle segmentation,supplemented by a noise filtering method to accurately estimate obstacle distance.Finally,an adaptive control strategy is designed to dynamically regulate the robot's speed,thereby ensuring safety.The algorithm is tested on a developed mobile robot platform.Experimental results show that the proposed method achieves a velocity estimation error below 10%.For obstacle segmentation task,the mean average precision and mean intersection over union reach 96.87%and 94.35%,respectively;and the mean depth error is within 0.24 m.

AIM:To identify the expression characteristics of transfer RNA-derived small RNAs(tsRNAs)re-sponding to DNA damage in human hepatoblastoma HepG2 cells,and to investigate their potential functions.METHODS:Based on paired HepG2 cells and TP53 gene knockout HepG2 cells,we successfully constructed a DNA damage cellular model using adriamycin(ADR).Transcriptome analysis of small noncoding RNAs was performed to systematically identi-fy a set of tsRNAs responding to ADR and involved in p53 regulation.Functional enrichment analysis was conducted using the Kyoto Encyclopedia of Genes and Genomes(KEGG).Additionally,after silencing the expression of target tsRNA genes,the biological functions of these tsRNAs in HepG2 cells were initially confirmed through CCK-8 assay and plate colo-ny formation assay.RESULTS:DNA damage induced a set of tsRNAs involved in p53 regulation,among which tRF-5-1(tRF-5_tRNA-Gly-TCC-2-1)and tRF-i-1(tRF i_tRNA-Tyr-GTA-11-1)showed the most significant up-regulation in HepG2 cells(P<0.05).Silencing of either tRF-5-1 or tRF-i-1 gene inhibited the proliferative activity of HepG2 cells(P<0.05).CONCLUSION:A group of tsRNAs responding to DNA damage can be identified in HepG2 cell model,and tsRNAs can promote the proliferative activity of HepG2 cells,suggesting that tsRNAs may play an important role in the de-velopment and progression of liver malignancies.
