Objective To investigate the current distribution of radiotherapy resources in Gansu Province, evaluate the equity of resource allocation, and provide a scientific basis for optimizing regional resource allocation. Methods A questionnaire survey was carried out to assess radiotherapy resources in medical institutions across Gansu Province, China. The equity of radiotherapy resource distribution and associated disparities were assessed using the Gini coefficient, Lorenz curve, and Theil index. Results A total of 23 medical institutions in Gansu Province provided radiotherapy services, comprising 39 radiotherapy devices and 438 professionals, of whom medical physicists accounted for 16.9%. The radiotherapy frequency was 0.47 cases per thousand population. The Gini coefficients for radiotherapy resource distribution ranged from 0.38 to 0.56 by population and from 0.52 to 0.70 by geography. The Theil index for radiotherapy resources ranged from 1.36 to 3.67. Conclusion Radiotherapy resources in Gansu Province were insufficient, and the capacity of radiotherapy service was suboptimal. The equity of radiotherapy resource allocation by geography was worse than that by population. Therefore, it is imperative to address the shortage of radiotherapy resources, strengthen the professional workforce, enhance the capacity radiotherapy service and resource utilization, optimize resource allocation, and promote regional equity in radiotherapy provision in Gansu Province.

ObjectiveTo analyze the comorbidity patterns of chronic metabolic diseases and their influencing factors among residents aged 35‒75 years old in Nantong City of Jiangsu Province, and to provide theoretical support for the prevention and control of comorbidities. MethodsThe permanent residents aged 35‒75 years from the Comprehensive Prevention and Control Project of Cardiovascular and Cerebrovascular Diseases in Nantong City from 2021 to 2024 were selected as the research subjects. Clustering analysis and association rule were used to investigate the comorbidity patterns of chronic metabolic diseases, and their influencing factors were identified through logistic regression analyses. ResultsThe prevalence of comorbidity of chronic metabolic diseases among residents aged 35‒75 years in Nantong City was 47.40%. Among comorbidity patterns based on disease counts, the prevalence of hypertension+dyslipidemia was highest in binary comorbidity patterns (6.25%), while that of hypertension+dyslipidemia+obesity was highest in ternary comorbidity patterns (4.01%). Association rules showed that in both binary and ternary comorbidity patterns, the confidence level was highest for obesity+hypertension (72.70%) and obesity+dyslipidemia+hypertension (74.54%). Renal insufficiency formed an independent cluster in cluster analyses. Logistic regression analyses revealed that, compared with the non-comorbidity group, males (OR=2.22, 95%CI: 1.69‒2.91), advanced age (45‒54 years, OR=1.38, 95%CI: 1.02‒1.88; 55‒64 years, OR=1.59, 95%CI: 1.14‒2.23; 65‒75 years, OR=2.34, 95%CI: 1.58‒3.47), and low physical activity (OR=1.26, 95%CI: 1.10‒1.65) were influencing factors for metabolic disease comorbidity. ConclusionIn the comorbidity patterns of chronic metabolic diseases among residents aged 35‒75 years in Nantong City, hypertension, diabetes mellitus, and dyslipidemia interact with each other. Individuals with obesity are more prone to diseases such as hypertension and dyslipidemia. Prevention and control of chronic metabolic diseases should be strengthened for males, individuals with low physical activity and advanced age.

Background: Coughing and hemodynamic fluctuations during emergence from anesthesia after a craniotomy can result in serious complications. This study evaluated whether the ultrasound-guided superior laryngeal nerve block (SLNB) attenuates these tracheal tube-related responses. Methods: Eighty patients scheduled for elective craniotomy were randomized into the control (Group C, 2 ml 0.9% saline per side) and SLNB (Group S, 2 ml 1% lidocaine per side) group. The primary outcome was the incidence of coughing during the recovery period. Secondary outcomes included the severity of coughing, hemodynamic fluctuations, need for rescue interventions, anesthesia-related parameters, and complications. Results: Compared to controls, the patients in Group S experienced a significantly reduced incidence (78.9% vs. 48.6%; P = 0.006) and severity (P < 0.001) of coughing during emergence. The mean arterial pressure and heart rate were also more stable during and after extubation in Group S than in Group C. Furthermore, Group S required a significantly lower dose of nicardipine during the emergence period (P = 0.032), and both the incidence of and visual analog scale scores for postoperative sore throat at 6 h after extubation were markedly reduced (P = 0.035). No significant differences were noted between the groups in terms of propofol consumption, emergence agitation, extubation time, post-anesthesia care unit stay duration, or complications. Conclusions The SLNB significantly suppressed extubation-related responses during anesthetic emergence after craniotomy by reducing coughing and attenuating hemodynamic fluctuations, thereby contributing to a smoother emergence profile.

Objective: To analyze and compare the levels of various coagulation factors in cryoprecipitate and corresponding fresh frozen plasma, thereby providing a basis for the precise clinical administration of cryoprecipitate. Methods: Fibrinogen, coagulation factors Ⅱ, Ⅴ, Ⅶ, Ⅷ, Ⅸ, Ⅹ, Ⅺ, Ⅻ, and ⅩⅢ, von Willebrand factor antigen (VWF∶Ag), and von Willebrand factor activity (VWF∶Act) were measured in cryoprecipitate and corresponding fresh frozen plasma prepared from 400 mL of whole blood. The levels of each coagulation factor were quantified and subjected to paired comparisons; the total coagulation factor content was also calculated for each bag of cryoprecipitate and fresh frozen plasma. Results: The fibrinogen level in the precipitate was (4.48±0.83) g/L, coagulation factor Ⅷ activity was (330.11±172.00) IU/dL, VWF∶Ag was (510.7±229.34) IU/dL, VWF∶Act was (341.35±116.21) IU/dL; the activities of other coagulation factors did not differ significantly from those in fresh frozen plasma. In each bag of cryoprecipitate (47.7±1.68) mL, the fibrinogen content was (211.94±39.6) mg, the coagulation factor Ⅷ content was (156.67±79.82) IU, the VWF∶Ag content was (245.18±103.25) IU, VWF∶Act was (164.21±54.30) IU. Paired comparisons between cryoprecipitate and fresh frozen plasma revealed that the concentrations of Fib, FⅧ, FⅨ, FⅪ, FⅫ, FⅩⅢ, VWF∶Ag, and VWF∶Act in cryoprecipitate were all higher than those in fresh frozen plasma, with statistically significant differences (P<0.05). Conclusion: Fresh frozen plasma and cryoprecipitate can serve as treatment options for patients with coagulation factor deficiencies. The results provide data to guide the precise selection of blood products and the rational use of blood in clinical practice.

Objective To propose a framework for risk assessment and stepwise management of pulmonary nodules based on existing guidelines and key studies, and to clarify the boundaries for triage, workup escalation, and referral in different detection scenarios. Methods A problem-oriented evidence synthesis approach was used, prioritizing Chinese expert consensus, Fleischner Society Guidelines, British Thoracic Society (BTS) Guidelines, and Lung-RADS. This was supplemented by studies on risk models, imaging measurements, liquid biopsy, tissue sampling, and surgical treatments. This paper is not presented as a formal consensus or a validated clinical pathway. Results A three-tiered framework consisting of basic non-invasive assessment, advanced assessment, and invasive diagnosis was established. It specified the applicable populations, boundaries for the use of risk models, imaging review, management of conflicting results, evaluation of histopathological consistency, and post-intervention follow-up. Liquid biopsy, genetic testing, and artificial intelligence were defined as investigational or adjunctive tools. Conclusion This framework can serve as a preliminary reference for multidisciplinary teams in developing local protocols. It cannot replace applicable guidelines, pathological diagnosis, shared decision-making with patients, or real-world validation.

Objective: To investigate the epidemiological characteristics of human brucellosis in Jiande City, Zhejiang Province from 2005 to 2024, so as to provide the evidence for strengthening the prevention and control of brucellosis. Methods: Data on brucellosis cases and surveillance in Jiande City from 2005 to 2024 were collected through the Chinese Disease Prevention and Control Information System, the annual brucellosis surveillance reports from the Jiande Center for Disease Control and Prevention, and the annual summaries of brucellosis prevention and control efforts. The epidemiological characteristics of human brucellosis were analyzed using a descriptive epidemiological method. Results: A total of 1 125 individuals were monitored in Jiande City from 2005 to 2024, with 18 seropositive cases identified and the seropositivity rate of 1.60%. The average annual seropositivity rate from 2015 to 2024 was 3.35%, which was significantly higher than that of 0.57% from 2005 to 2014 (P<0.05). There were 10 confirmed brucellosis cases and 8 asymptomatic infections, with no reported deaths. The peak incidence occurred between March and August. Among the 16 towns (streets) in Jiande City, 8 reported brucellosis cases. Of the brucellosis cases, 14 were male and 4 were female, with a male-to-female ratio of 3.5∶1. The majority of cases (13 cases) were aged between 40 and 60 years. Occupational exposure was identified in 16 cases, all of whom were infected through direct hand contact with the excreta, secretions, or animal products of infected sheep or cattle. The primary source of infection was sheep, followed by cattle. Five strains of Brucella were isolated and cultured, all identified as Brucella melitensis biovar 3. Conclusions The brucellosis epidemic in Jiande City remained at a sporadic and low prevalence level from 2005 to 2024, with an increasing trend observed from 2015 to 2024. Male occupational groups aged 40 to 60 years were the key population for brucellosis prevention and control, and sheep were the primary source of infection.

[Objective]To explore the efficacy of warm acupuncture combined with Guizhi Shaoyao Zhimu Decoction in the treatment of knee osteoarthritis and its effect on synovial hyperplasia.[Methods]A total of 106 patients with knee osteoarthritis treated at the Nanjing Integrated Traditional Chinese and Western Medicine Hospital from January 2022 to January 2024 were selected and randomly divided into two groups by using a computer-generated random number method,53 patients in observation group and 53 patients in control group.The control group was treated with Guizhi Shaoyao Zhimu Decoction,while the observation group received Guizhi Shaoyao Zhimu Decoction combined with warm acupuncture.After one month of treatment,the traditional Chinese Medicine(TCM)syndromes,knee joint function,inflammatory factors including tumor necrosis factor-α(TNF-α),interleukin-1(IL-1),matrix metalloproteinase-3(MMP-3),synovial hyperplasia indicators such as cartilage oligomeric matrix protein(COMP),osteoprotegerin(OPG)and fibroblast growth factor-2(FGF-2)were compared between the two groups.The therapeutic efficacy and adverse reactions were also evaluated.[Results]After treatment,the joint pain,difficulty in extension and flexion,exacerbation in cold weather and heaviness of the limbs in both groups decreased,with observation group showing significantly lower scores than control group(P<0.05).After treatment,the Lysholm knee function score,knee flexion angle,OPG and FGF-2 levels in observation group were higher than those in control group(P<0.05),while COMP was lower(P<0.05).The levels of TNF-α,IL-1 and MMP-3 decreased in both groups,with observation group showing lower levels than control group(P

Cervical spinal cord injury without fracture-dislocation (CSCIWFD) is referred to as a special type of cervical spinal cord injury characterized by traumatic spinal cord dysfunction and no significant bony structural abnormalities on imagines. Duo to the high risk of missed diagnosis during the initial consultation, CSCIWFD may lead to progressive neurological deterioration or even complete paralysis, severely impacting patients′ prognosis. Currently, there are no established consensuses over the diagnosis and treatment of CSCIWFD, such as the lack of evidence-based standards for indications of non-surgical treatment and risk of secondary neurological injury, as well as debates over the optimal timing for surgical intervention and indications for different surgical approaches. To address these issues, the Spine Trauma Group of the Orthopedic Branch of the Chinese Medical Doctor Association organized experts in the relevant fields to formulate Diagnosis and treatment guideline for acute cervical spinal cord injury without fracture- dislocation in adults ( version 2025) . Based on evidence-based medicine and the principles of scientific rigor and clinical applicability, the guidelines proposed 11 recommendations covering terminology, diagnosis, evaluation treatment, and rehabilitation, etc., aiming to standardize the management of CSCIWFD.

Vertebral refracture following percutaneous vertebral augmentation (PVA) is commonly seen in elderly patients with osteoporotic thoracolumbar compression fractures (OTLCF). It can lead to recurrent pain, loss of vertebral height, progression of kyphosis, and even neurological dysfunction, significantly impairing patients′ quality of life. Current diagnosis and treatment face multiple challenges, including high misdiagnosis rate, difficulty in choosing between surgical and non-surgical treatment options, lack of standardized surgical protocols, interference from intralesional bone cement during procedures, inadequate stability of internal fixation in osteoporotic bone, and suboptimal compliance of anti-osteoporotic therapy. Establishing a standardized diagnostic and therapeutic framework is urgently needed. To standardize the management process and improve outcomes for vertebral refractures after PVA in elderly OTLCF patients, Spinal Trauma Group of the Orthopedic Branch of Chinese Medical Doctor Association organized experts in the field to develop Guideline for the diagnosis and treatment of vertebral refracture after percutaneous vertebral augmentation in elderly patients with osteoporotic thoracolumbar compression fractures ( version 2025), based on current literature and clinical experience, and adhering to principles of scientific rigor and clinical applicability. A total of 11 recommendations were proposed, encompassing diagnosis, treatment, and rehabilitation of vertebral refracture after PVA in elderly patients with OTLCF, aiming to provide a foundation for a standardized management.

Thoracolumbar spine fracture often leads to severe pain, functional impairments, and neurological deficits, for which open reduction and internal fixation can effectively restore the spinal structural stability. Open decompression and reduction with internal fixation can help relieve spinal cord compression and improve spinal function in cases of concomitant cord injury. Although spinal stability can be restored through surgery, patients often face chronic pain and functional impairments postoperatively. A postoperative rehabilitation program is critical in optimizing therapeutic outcomes, reducing complications, and minimizing the risk of secondary injuries. However, current rehabilitation methods, such as physical therapy, functional training, and pain management, are confronted with problems in clinical practice, including significant variation in efficacy, poor patient adherence, and prolonged rehabilitation period. There is an urgent need for a unified rehabilitation strategy to address these problems. To this end, the Spinal Trauma Group of the Orthopedic Physicians Branch of the Chinese Medical Association and the Spine Health Professional Committee of the Chinese Human Health Technology Promotion Association organized experts from relevant fields to formulate Evidence-based guidelines for rehabilitation treatment after internal fixation of thoracolumbar spine fracture in adults ( version 2025) by integrating evidences from clinical researches and advanced rehabilitation concepts at home and abroad. A total number of 14 recommendations concerning the rehabilitation treatment with multimodal analgesia, psychological intervention, deep vein thrombosis prevention, core muscle and extremity exercise, appropriate use of braces, early weight-bearing, device-aided rehabilitation exercise, neuroregulatory therapy, rehabilitation team were put forward, aiming to standardize the post-operative rehabilitation process following internal fixation, promote the functional recovery, and enhance patients′ quality of life.
