The promulgation of the Technical Specifications for Clinical Use of Blood (2025 Edition) signifies that China's clinical blood transfusion management has transitioned from mere technical operations to a new stage centered on patient blood management (PBM). Through an in-depth comparison of the new and old specifications, this paper analyzes the core transformations regarding conceptual reconstruction, legal alignment, technological upgrades, and closed-loop management. The new specifications establish PBM principles, reinforce legal safeguards for informed consent and emergency treatment, and construct a comprehensive, refined quality control system by specifying compatibility testing standards and introducing a post-transfusion evaluation system. Medical institutions should seize this opportunity to update management protocols and information systems, deepen multidisciplinary collaboration, and drive the profound transformation of clinical blood use from focusing solely on safety assurance to placing equal emphasis on science and value.

ObjectiveTo evaluate the public health governance capacity in Jiangsu Province and provide an optimized pathway for the construction of a “strong, rich, beautiful, and high-quality” new Jiangsu. MethodsA total of 806 policy documents, 658 public information reports, and 148 research literatures related to public health governance capacity in Jiangsu Province from January 1995 to December 2023 were collected. The status of current public health goverance was assessed based on the evaluation criteria suitable for public health systems, and the strengths and the weaknesses of the system were identified. ResultsThe public health governance capability of Jiangsu Province was scored at 738.3 points, ranking 3rd nationally. Maternal health care and emergency response capacities achieved leading positions nationwide, both ranking 2nd. Jiangsu had exhibited a standardized guidance in the strategic level, a well-established management mechanism, an extensive coverage in information collection, and a scientifically established health targets setting. However, bottlenecks remained, including an unclear division of responsibilities across organizational departments, an insufficient public-health workforce, the absence of a stable growth mechanism for government funding investment, and difficulties in promptly identifying public needs. ConclusionJiangsu’s public-health system demonstrates leading nationally, yet several components remain underdeveloped. Future efforts should consolidate advantages while addressing weaknesses, further diversify content and forms, establish a stable funding increase mechanism, and clarify departmental functions, thereby providing solid health support for realizing the developmental goals of a “strong, rich, beautiful and high-quality” new Jiangsu.

ObjectiveTo systematically assess the public health governance capacity in Zhejiang Province, to conduct an in-depth analysis of its strengths and weaknesses, so as to provide scientific basis and strategic recommendations for further enhancement. MethodsA systematic collection of policy documents, public information reports, and research literature related to public health governance capacity in Zhejiang Province from 2002 to 2023 was conducted (encompassing a total of 1 263 policy documents, 138 pieces of information reports and 631 research articles). Based on the evaluation criteria suitable for public health systems previously developed by the research team, the basic status and magnitude of change in public health governance capacity in Zhejiang Province was evaluated. Additionally, normative gap analyses were employed to identify the strengths and weaknesses. ResultsZhejiang Province ranked 4th nationwide in terms of public health governance capacity with a score of 733.4 points (1 000.0-point maximum). The province has effectively implemented the principle of health first (scoring 698.5 points in the assessment of health-first strategy implementation) and attached sufficient importance to health-related goals (scoring 658.2 points in the scientific rationality of goal setting). However, the implementation of inter-departmental coordination and incentive mechanisms only scored 178.7 points, the feasibility of management and monitoring mechanisms scored even lower at only 144.0 points, and the coverage of incentive mechanisms scored 286.0 points. ConclusionZhejiang Province has effectively implemented its health first strategy and attached great importance to health targets, but still needs to strengthen cross-departmental coordination mechanisms and health-oriented incentives.

Objective:To investigate the feasibility and safety of radical thyroidectomy through a small incision in the side neck of the sternocleidomastoid intermuscular approach.Methods:Clinical data of newly treated patients with papillary thyroid carcinoma admitted to the Department of Thyroid-Otolaryngology and Head and Neck Surgery,Sichuan Cancer Hospital from Feb. 2022 to Mar. 2024 were collected. They were divided into SMIA group and LACA group according to surgical methods. In the SMIA group, 52 cases were treated by the sternocleidomastoid intermuscular approach with a small incision on the side of the neck. In the LACA group, 100 cases were treated by the cervical white line approach with a low cut incision on the front of the neck. Clinical data of the two groups, such as perioperative related indicators,postoperative aesthetic effects and postoperative complications were collected. Independent sample t test or Mann-Whitney U test were compared between the measurement data groups. Chi-square test was used for comparison between data sets. Results:There was no significant difference in demographic and clinical characteristics of tumor between the two groups. Compared with the control group,the operation time of the observation group was longer (83.85±18.72minvs71.33±15.50min, t=4.39, P<0.001) , the total postoperative drainage volume was significantly reduced (61.29±41.80ml vs. 99±35.80ml, Z=-4.65, P<0.001) , and the extubation time was significantly shortened (2.81±0.82d vs. 3.19±0.66d, Z=-3.31, P<0.001) , and the difference was statistically significant. There was no difference in postoperative transient hoarseness between the two groups ( χ 2=0.01, P=0.932) . Patient’s self-feeling was followed up one month after surgery. The number of patients with swallowing discomfort in the SMIA group was significantly lower than that in the LACA group ( χ2=4.30, P=0.017) . There was no significant difference between the two groups in neck stiffness ( χ2=3.16, P=0.075) , scar hyperplasia ( χ2=0.04, P=0.840) , and incision aesthetic effect score ( Z=-0.73, P=0.468) . Conclusions:Radical thyroidectomy through a small incision in the side neck of the sternocleidomastoid muscle is a safe, feasible and aesthetic mode of operation. It’s worth promoting in clinical practice,especially for patients with unilateral tumor and early tomur T stage.

Objective To investigate the effects of chronic restraint stress for 28 days(day and night)on mood and cognitive-like behavior in male and female ICR mice,to provide a basis for the selection of sex and restraint period in chronic restraint stress model animals.Methods A total of 72 male and female(1∶1)ICR mice were divided into six groups:male control,daytime restraint,and nighttime restraint groups,and female control,daytime restraint,and nighttime restraint groups.Mice in all but the control groups were bound for 10 h/d and restrained continuously for 28 days to establish a chronic restraint stress model.The emotional and cognitive behaviors induced by restraint in male and female mice at different times were observed by open field,Y maze,novel inhibition feeding,elevated cross maze,tail suspension,forced swimming,and dark-avoidance experiments.Results In the tail suspension experiment,the immobility time of male mice in the daytime restraint group was significantly increased compared with that in the control group(P＜0.05),and the immobility times of male mice in the daytime and nighttime restraint groups were also significantly increased in the forced swimming experiment,compared with those in the control group(P＜0.05).There was no significant difference between the female daytime restraint and female control groups in the novelty inhibition feeding experiment,but the feeding latency of the nighttime restraint group was significantly longer than that of the control group(P＜0.05)and the daytime restraint group(P＜0.05).The feeding latency of female mice was significantly longer than that of males during nighttime restraint(P＜0.05).In the open field test,compared with the male control group,the female control group showed a significant decrease in central area time and the ratio of central area time to peripheral area time(P＜0.05).Compared with the female control group,the female daytime restraint group exhibited a significant decrease in central area time and the ratio of central area time to peripheral area time(P＜0.05).There was no significant difference between the groups in the elevated cross maze and Y maze experiments.There was no significant difference in dark latency between the daytime restraint group and the control group,but darkness latency was significantly shorter in the nighttime restraint group compared with those in the control group(P＜0.05).When male and female mice were combined,the immobility time in the daytime restraint group was significantly increased in the tail suspension experiment(P＜0.05),the immobility times of mice in the daytime and nighttime restraint groups were significantly increased in the forced swimming experiment(P＜0.01,P＜0.05),and the central zone time and the ratio of central area time to peripheral area time of daytime restraint mice were significantly shorter compared with those in the control group(P＜0.05,P＜0.01).There was no significant difference in the central zone time and the ratio of central area time to peripheral area time in the nighttime restraint groups,and no significant difference in average speed or total distance between the daytime and nighttime restraint groups.Conclusions Male mice exhibited depression after 28 d of chronic restraint stress during the daytime,while female mice were prone to anxiety after 28 d of chronic restraint stress.Male mice experienced learning and memory impairment after 28 d of chronic restraint stress during the night.

BACKGROUND:Hemivertebra deformity should be treated surgically at an early age,but the risk factors for progression of deformity after hemivertebral resection have not been established.OBJECTIVE:To investigate the curative effect of one-stage posterior hemivertebrae resection and pedicle screw fixation in the treatment of congenital scoliosis,and to further explore the risk factors causing the progression of postoperative deformity.METHODS:The medical records of patients who underwent pedicle screw-rod fixation for unilateral hemivertebral deformity from January 2012 to February 2020 and were followed up for at least 2 years were retrospectively analyzed,and a total of 116 patients met the inclusion criteria.All patients were treated with standing anterior and lateral spinal radiographs taken before,after and at each follow-up time point.The segment Cobb angle,the total scoliosis Cobb angle,the proximal complementary Cobb angle,the distal complementary Cobb angle,and the coronal balance distance,apical vertebra distance,upper instrumented vertebra tilt,upper instrumented vertebra disc angle,lower instrumented vertebra tilt,lower instrumented vertebra disc angle,segmental kyphosis/lordosis,thoracic kyphosis,lumbar lordosis and sagittal vertical axis were measured.The progression of deformity and complications were also recorded.RESULTS AND CONCLUSION:(1)Segment Cobb,total scoliosis Cobb,segmental kyphosis,proximal complementary Cobb,and distal complementary Cobb were significantly corrected after operation(P＜0.05),and remained corrected at the last follow-up.Thoracic kyphosis,lumbar lordosis,coronal balance distance,and sagittal vertical axis were all in the normal range pre-operation,after operation and at the last follow-up.(2)During follow-up,10 patients developed coronary decompensation,which was characterized by abnormal progression.(3)Independent sample t-test showed that preoperative total scoliosis Cobb,preoperative apical vertebra distance,age,Risser sign,postoperative upper instrument vertebra tilt and postoperative lowest instrumented vertebra tilt were correlated with postoperative malformation progression(P＜0.05).(4)Multivariate Logistic regression analysis showed that postoperative lowest instrumented vertebra tilt was an independent risk factor for postoperative malformation progression(P=0.002,OR=1.526).(5)Receiver operating characteristic curve analysis showed that a postoperative lowest instrumented vertebra tilt of 8.14° was the optimal threshold for deformity progression after hemivertebrae resection and pedicle rod fixation(sensitivity 0.900,specificity 0.906,area under curve:0.926).(6)It is indicated that the treatment of congenital scoliosis with one-stage posterior hemivertebrae resection and pedicle nail fixation can achieve satisfactory orthopedic effect.Postoperative lowest instrumented vertebra tilt greater than 8.14° was an independent risk factor for postoperative coronal decompensation.

BACKGROUND:Ligament rupture and defect of the lateral or medial malleolus caused by high-energy injuries are common challenges in foot and ankle surgery.Their neighboring core tendons are often used as grafts to reconstruct the deficient ligaments.It is of paramount importance to investigate the mechanical properties of such tendons in the context of ligament defects to provide a suitable donor tendon.OBJECTIVE:To investigate the interactive dynamics and biomechanical alterations among their core tendons during ankle joint motions under varying degrees of lateral or medial malleolar ligament defect.METHODS:Based on CT imaging data of the left foot of a 50-year-old healthy male,a surface stereolithography model was extracted and constructed using MIMICS software.After Geomagic Wrap software was employed to fit the surfaces,a bone-cartilage-ligament-tendon ankle complex model incorporating varying degrees of ligament deficiencies was created within SOLIDWORKS software.Finite element analysis was then conducted using Ansys Workbench software,and the model's validity was verified through a simulated anterior drawer test.Following validation,the mechanical response of the ankle under the conditions of internal and external rotation,as well as inversion and eversion,was simulated.The variation and distribution patterns of the maximum Von-Mises stress in the peroneus brevis and longus tendons,as well as the anterior and posterior tibial tendons,were observed.RESULTS AND CONCLUSION:(1)In the anterior drawer test,the maximum talar displacement reached 5.208 5 mm,which was similar to the data in the previous literature,thereby the effectiveness of the model was validated.(2)Under four loading conditions,the defect of unilateral single-bundle ligaments exerted minimal influence on the maximum stress of adjacent core tendons,whereas the defect of unilateral multi-bundle ligament significantly increased the maximum tendon stress.Except for the consistently high stress across segments of the anterior tibial tendon,the high-stress regions in the long and short peroneal tendons and posterior tibial tendon were concentrated at their distal ends near the insertions.(3)Regarding the defect of the lateral malleolar ligament,the maximum stress and its variation in the peroneus brevis tendon during inversion and internal rotation were higher than those in the peroneus longus tendon.During inversion under the condition of the defect of the anterior talofibular ligament,the maximum stress in the short peroneal tendon increased by 0.951 2 MPa compared to that of normal condition,while that in the long peroneal tendon decreased by 0.065 1 MPa.Under the condition of the defect of the calcaneofibular ligament during internal rotation,the maximum stress in the short peroneal tendon increased by 2.352 9 MPa,while the maximum stress in the long peroneal tendon decreased by 0.269 2 MPa.(4)During eversion and external rotation under the defect of medial malleolar ligament,the variations in the maximum stress of the anterior and posterior tibial tendons were complex and depended on the type of ligament defect.Notably,full-thickness ligament defect significantly augmented the maximum stress in both tendons.

The gastrin-releasing peptide receptor(GRPR)is highly expressed in various malignant tumors(e.g.,glioblastoma,prostate cancer,and breast cancer)and has emerged as an important molecular target for precision cancer diagnosis and therapy.In recent years,the combined application of radionuclide-la-beled GRPR ligands with positron emission tomography/computed tomography(PET/CT)has achieved ground-breaking progress in noninvasive diagnosis,accurate staging,and therapeutic monitoring of GRPR-positive tumors.Meanwhile,GRPR-targeted radionuclide therapeutics have demonstrated significant therapeutic potential and promising clinical applications in trials.This GRPR-based theranostic strategy pioneers a novel ap-proach for precision medicine in GRPR-overexpressing tumors.

China emerges as a major country in nuclear energy development and the application of nuclear and radiologic technology. The diagnosis and treatment of acute radiation syndrom (ARS) caused by external irradiation represent a core function in the country′s medical rescue of nuclear and radiological emergencies. Clinically, ARS manifests hematopoietic, gastrointestinal, cutaneous, and central nervous system syndromes, with specific clinical manifestations, signs, severity, and prognosis strongly correlated with radiation dose. China has established a number of national and provincial centers for treating radiation-induced damage. Nevertheless, most medical staff have limited experience in ARS treatment. This consensus presents a summary of recent experience in treating ARS of China. In combination with recommendations from international organizations such as the World Health Organization (WHO), this consensus proposes key evidence of critical clinical issues of ARS, covering all links in the rescue of external irradiation-induced ARS. Initially, clinical diagnosis, syndromes, and severe degrees should be determined based on clinical symptoms and dose estimates. It is necessary to normalize clinical treatment measures for hematopoietic recovery, gastrointestinal injury treatment, infection control, symptomatic treatment, and multi-organ function preservation. To this end, this consensus offers cautions. This consensus provides principles of treatment with traditional Chinese medicine, psychological intervention, and follow-up. Additionally, it highlights multidisciplinary collaboration. It is recommended that this consensus be applied in relevant treatment centers.
