ObjectiveTo investigate the efficacy of selective internal radiation therapy （SIRT） in patients with unresectable hepatocellular carcinoma， and to provide a reference for the selection of clinical treatment regimens. MethodsA retrospective analysis was performed for the clinical data of 73 patients with unresectable hepatocellular carcinoma who received yttrium-90 microsphere SIRT in Eastern Hepatobiliary Surgery Hospital from May 1， 2023 to September 1， 2024. According to tumor characteristics， physical status， liver reserve function， laboratory tests， and SIRT treatment strategy， the patients were divided into radiation segmentectomy group with 9 patients， conversion therapy group with 47 patients， and palliative treatment group with 17 patients. Based on the results of postoperative follow-up， modified Response Evaluation Criteria in Solid Tumors were used to assess radiographic images. A one-way analysis of variance was used for comparison of normally distributed continuous data between three groups， and the chi-square test was used for comparison of categorical data between three groups； the Logistic regression model was used to perform the multivariate analysis. ResultsThere was a significant difference in postoperative outcome between the radiation segmentectomy group， the conversion therapy group， and the palliative treatment group （χ²=30.060， P<0.001）. The disease control rate was 100.0% （9/9） in the radiation segmentectomy group， 83.0% （39/47） in the conversion therapy group， and 29.4% （5/17） in the palliative treatment group， with a significant difference between the three groups （χ²=19.575， P<0.001）， and there was also a significant difference in objective response rate between the three groups （χ²=17.749， P<0.001）. The multivariate Logistic regression analysis showed that the number of tumors （odds ratio ［OR］=0.085， 95% confidence interval ［CI］： 0.008 — 0.906， P=0.041） and combined targeted immunotherapy （OR=18.808， 95%CI： 1.704 — 207.616， P=0.017） were independent influencing factors for achieving complete response. ConclusionThe number of tumors is an independent influencing factor for the efficacy of SIRT and is an important basis for selecting different treatment goals. SIRT combined with targeted immunotherapy may achieve better efficacy.

Purpose: This study aimed to evaluate the safety and efficacy of gemcitabine and cisplatin (GP) regimen in combination with immune checkpoint inhibitor sintilimab as neoadjuvant therapy for muscle-invasive bladder cancer (MIBC) patients and the feasibility of the following selective bladder sparing surgery. Materials and Methods: Patients with histopathologically confirmed urothelial carcinoma without distant metastases (T2-4a, N ≤ 1, M0, American Joint Committee of Cancer 8th) and with adequate organ function will be enrolled. The therapeutic regimen was sintilimab 200 mg once on day 8, gemcitabine 1,000 mg/m2 and cisplatin 35 mg/m2 once on days 1 and 8, every 21 days for four cycles. The primary endpoint was pathologic complete response (pCR, pT0N0) rate. The secondary end points were ypT < 2 rate, R0 resection rate, event-free survival, and safety. Results: From May 4, 2020, to May 20, 2023, 55 patients were enrolled. Forty-six patients were evaluated for efficacy. Among the 42 patients who underwent surgery, 16 patients (38.0%) achieved pCR. Thirty-three patients (78.6%) achieved pT < 2. With a median follow-up of 15.7 months, the 1-year event-free survival was 91.3%. Notwithstanding the poor pathological baseline characteristic of a high T3-T4a proportion (39.1%), a promising bladder preservation (including 22 patients transurethral resection of bladder tumor, 5 patients partial cystectomy, and 4 surveillances) rate was achieved (67.4%). The most common grade ≥ 3 treatment-related adverse events was neutropenia (n=15, 27.3%), which was related to chemotherapy. There were no grade 3 immune-related adverse events. Conclusion Neoadjuvant GP plus sintilimab is a promising regimen for MIBC patients, with relatively high pT < 2 rate and triggering the emerging roles for the multi-disciplinary team decision-making for bladder sparing surgery.

Objective:To explore the hemodynamic characteristics of the middle cerebral artery (MCA) in atherosclerotic stenosis using four-dimensional flow (4D Flow) MRI, and combining high-resolution magnetic resonance vessel wall imaging (HR VW-MRI) to analyze the relationship between hemodynamics and the degree of stenosis, as well as the morphological characteristics of plaques.Methods:The study was a cross-sectional study. A total of 24 patients with middle cerebral artery(MCA) M1 atherosclerotic stenosis and 10 age and sex matched healthy controls (HC group) were prospectively recruited from September 2018 to March 2021 at Beijing Tiantan Hospital, Capital Medical University. All subjects underwent MRI examination. The hemodynamic of MCA were collected by 4D Flow MRI, and the hemodynamic parameters of proximal and distal MCA stenosis were calculated by blood flow post-processing software, including average blood flow rate (FR avg), average blood flow velocity (V avg), peak blood flow velocity (V pk), time average wall shear stress (TAWSS), minimum wall shear stress (WSS min) and oscillatory shear index (OSI). The differences in hemodynamic parameters among the proximal and distal ends of MCA stenosis and the HC group were compared using one-way ANOVA or Kruskal-Wallis H test. The stenosis rate and characteristics of MCA plaque were analyzed by HR VW-MRI, including remodeling index (RI), normalized wall index (NWI) and plaque length. Pearson or Spearman correlation analysis was used to explore the correlation between stenosis rate and hemodynamic parameters. Taking the stenosis rate as the control variable, partial correlation analysis was used to explore the correlation between plaque morphological characteristics and hemodynamic parameters. Results:There were statistically significant differences in FR avg, V avg, V pk, TAWSS, OSI, WSS min among the proximal and distal stenosis of MCA and HC groups ( P<0.05). The proximal end of the MCA stenosis had significantly higher FR avg, V avg, TAWSS and WSS min than those of the distal end of the stenosis ( P<0.01). The FR avg, V avg, V pk, TAWSS, and WSS min in the distal end of MCA stenosis were lower than those in the HC group, while the OSI was higher than that in the HC group ( P<0.01). The correlation analysis results showed that the MCA proximal V pk ( r=-0.425, P=0.027) and distal V pk ( r=-0.538, P=0.004) were negatively correlated with the diameter stenosis rate. When the stenosis rate was taken as the control factor, in the MCA proximal stenosis, V avg ( r=0.553, P=0.003), TAWSS ( r=0.543, P=0.004) and WSS min ( r=0.547, P=0.004) were positively correlated with RI, proximal OSI was negatively correlated with RI ( r=-0.492, P=0.011), and was positively correlated with the plaque length ( r=0.437, P=0.026). At the distal end of the stenosis, V pk was negatively correlated with NWI ( r=-0.556, P=0.003), OSI was negatively correlated with RI ( r=-0.511, P=0.008), NWI ( r=-0.390, P=0.049). TAWSS was positively correlated with RI ( r=0.393, P=0.047). Conclusions:The 4D Flow MRI demonstrates characteristic hemodynamic changes in the proximal and distal ends of the stenotic MCA. The local hemodynamic characteristics of the stenotic MCA are correlated with plaque morphological parameters, including lumen stenosis, plaque load, and RI. It suggests an interaction between the occurrence and development of MCA plaque and local hemodynamic changes.

Objective:To observe the therapeutic effect of combining low-frequency pulsed electrical stimulation with Beckman oral muscle exercise training in relieving drooling among persons with Parkinson′s disease (PD).Methods:A random number table was used to divide 120 PD patients with drooling into a mouth muscle training group, an electrical stimulation group, and an observation group, with 40 patients in each group. In addition to routine medication, the oral muscle training group was given Beckman oral muscle exercise training, the electrical stimulation group underwent low-frequency pulsed electrical stimulation treatment, while the observation group was provided with both. Before and after 4 weeks of treatment, the severity of salivation, the frequency of repeated empty swallowing, oral motor function, saliva secretion, and life quality of the three groups were evaluated using the Saliva Rating Scale (DRS), the Repeated Saliva Swallowing Test (RSST), oral motor function grading, the Parkinson′s Disease Saliva Clinical Scale (SCS-PD), saliva weighing, and the PD Quality of Life Scale (PDQ-39).Results:After the treatment the average DRS, SCS-PD, saliva weighing and PDQ-39 results of the observation group were significantly better than those before treatment and better than the other 2 groups′ averages. That group′s average RSST and oral motor function scores had increased significantly compared to before treatment, and compared with the other 2 groups′ averages at the same time point.Conclusions:Combining low-frequency pulsed electrical stimulation with Beckman oral muscle exercise can improve oral motor function, swallowing, and the life quality of PD patients who drool. It is more effective than electrical stimulation or oral muscle exercise training alone. Such combination therapy is worthy of clinical promotion and application.

Spine fracture and dislocation are common traumatic spinal conditions that often require surgical intervention due to compromised spinal stability. Surgical approaches include anterior, posterior, and combined anterior-posterior spinal procedures. According to the specific surgical requirements, patients may be placed in the prone position or repositioned between prone and supine positions during surgery. Intraoperative repositioning has become an essential step in patient positioning. However, during repositioning, patients with spinal fracture and dislocation are at increased risk for complications such as hemodynamic instability, nerve injury, and pressure injuries to the skin and soft tissue. Notably, due to the instability of the spinal cord, even minor manipulations can further exacerbate the damage, potentially leading to severe outcomes like paraplegia. Although the current clinical guidelines provide instructive recommendations for standard position, there remains no specific protocols for intraoperative repositioning in patients with spine fracture and dislocation. With a concern for the lack of clinical studies on positioning techniques, risk prevention, and operational norms for special patients, no applicable guidelines or standards are available. A consensus was required to provide clinical reference, meet the requirements of surgical treatment, and minimize the safety risks of patients caused by improper placement of positions. Professional Committee of Operating Room Nursing of Shaanxi Nursing Association organized experts in nursing management and operating room nursing from major hospitals across China to formulate Expert consensus on intraoperative repositioning for patients with spinal fracture and dislocation ( version 2025). The consensus provides 11 recommendations covering pre-repositioning preparation, intraoperative maneuvers, and post-repositioning observation, aiming to provide references for clinical standardization of the intraoperative repositioning process and protection of patients′ safety.

Objective:To investigate whether continued low-dose aspirin (LDA) intervention affects the incidence of pre-eclampsia (PE) and adverse pregnancy outcomes in pregnant women with high-risk PE screening in the first trimester and reassessed as low risk at 28 weeks of gestation.Methods:This study was a prospective observational cohort study. From April 2022 to April 2024, a total of 106 pregnant women who underwent prenatal examination in the Affiliated Jiangyin Hospital of Nantong University were enrolled. They were assessed as high risk of PE by multiple indicators combined screening at 11-13 +6 weeks of gestation, received LDA intervention, and were reassessed as low risk of PE at 28 weeks of gestation. The patients were divided into withdrawal group (49 cases) and continuation group (57 cases). The incidence of PE and adverse pregnancy outcomes were compared between the two groups. Results:(1) There were no statistically significant differences in general conditions and the incidence of pregnancy complications between the two groups (all P>0.05). During the PE risk screening at 11-13 +6 weeks of gestation, there were no statistically significant differences in mean arterial pressure (MAP) and ultrasound uterine artery pulsation index (UtPI) between the two groups (all P>0.05), but the placental growth factor (PlGF) level in the withdrawal group was significantly lower than that in the continuation group ( P=0.023). There was no significant difference in the proportion of pregnant women with high risk of PE before 32 weeks and 34 weeks of pregnancy between the two groups (all P>0.05). (2) There were 7 cases (14%, 7/49) of PE in the withdrawal group, including 1 case (2%, 1/49) of early-onset PE and 3 cases (6%, 3/49) of PE before 37 weeks of pregnancy. There were 11 cases (19%, 11/57) of PE in the continuation group, including 2 cases (4%, 2/57) of early-onset PE and 4 cases (7%, 4/57) of PE before 37 weeks of pregnancy. There were no significant differences in the incidence of PE (including early-onset PE and PE before 37 weeks of pregnancy), gestational hypertension, severe PE, chronic hypertension complicated with PE and chronic hypertension complicated with pregnancy between the two groups (all P>0.05). (3) There were no significant differences in cesarean section rate, preterm birth rate, placental abruption, postpartum hemorrhage, fetal growth restriction, fetal distress rate, neonatal birth weight, neonatal asphyxia, and 1-minute and 5-minute Apgar scores between the two groups (all P>0.05). No stillbirth occurred in the two groups. Conclusion:For pregnant women with high risk of PE screening in the first trimester and taking LDA intervention, there is no difference in the incidence of PE and adverse pregnancy outcomes whether to continue LDA or not after being reassessed as low risk at 28 weeks of gestation.

OBJECTIVE To explore the epidemiological characteristics of common allergens among children with al-lergic rhinitis(AR)in a children's specialized hospital of Beijing.METHODS A total of 2120 children who met the diagnostic criteria of AR and were treated in otolaryngology department of Beijing Jingdu Children's Hospital from 2021 to 2023 were recruited as the research subjects.The specific immunoglobulin E(sIgE)of allergens was de-tected by western blot quantitative assay.The positive rates of the allergens were statistically analyzed according to the age,sex and years.The epidemiological characteristics and changing trends were observed.RESULTS The pos-itive rate of allergens was 47.78％among the 2120 children,in whom multiple allergies polysensitization were pre-dominant;the positive rate of allergens and polysensitization rate were the highest among the population aged be-tween 1 and 7 years old.The inhalational allergens were dominant,and the positive rate of the Candida group was highest.The positive rates of inhalant allergens and ingested allergens reached the peak at the age of 1-7 and then declined with age;milk and egg white were the two types of predominant ingested allergens in childhood.Among the 2120 children,there were significant differences in the positive rates of allergens between the male and the fe-male,and the positive rates of the male were higher than those of the female(P＜0.001).The positive rates of al-lergens generally showed upward trends during the 3 years,the positive rates of the inhalant allergens such as mugwort,cat hair and dog dandruff ascended by a large margin,and the positive rates of the ingested allergens such as milk,egg white and egg yolk showed remarkable rising trends.CONCLUSIONS The causes of AR are complicated.There are a variety of factors affecting the allergen test.The epidemiological characteristics of the al-lergens among the AR children are observed from multiple perspectives,which may provide references for preven-tion and treatment of the children with AR.

As a key position in medical insurance reform, public hospitals bear the heavy responsibility of deepening medical reform. In the wave of new quality productive forces, the importance of medical insurance management in public hospitals is becoming increasingly prominent. New quality productive forces provides a theoretical breakthrough and practical path for the transformation of medical insurance management paradigm in public hospitals. The authors analyzed the underlying logic of the coupling of new quality productive forces and the high-quality development of medical insurance management in public hospitals from the academic level. Combined with the current dilemmas of medical insurance management in public hospitals, such as lagging management concept, weak digital governance ability, and management system and mechanism not adapting to the development requirements of new productive forces, the authors proposed a three-dimensional development path of " cognitive revolution, factor reconstruction, governance ecology" and constructed a closed-loop system of high-quality development of " value creation, technology empowerment, collaborative co-governance" , so as to provide theoretical innovation and practical path for the modernization of medical insurance management.
