Objective To explore the effect of the method of cooling blood and removing stasis on promoting the relief of swelling and pain symptoms and the recovery of joint mobility in the early stage of acute ankle sprains.Methods From January 2023 to January 2024,a total of 88 patients with early-stage acute ankle sprains admitted to the Eighth Clinical Medical School of Guangzhou University of Chinese Medicine(Foshan Hospital of Traditional Chinese Medicine)were selected.The patients were randomly divided into an observation group and a control group using a random allocation method(random number table),with 44 patients in each group.The control group was treated following the PRICE principle for acute sports injury,with the measures such as ice compress,immobilization,and compression.The observation group,in addition to receiving the same treatment as the control group,was given the decoction of Liangxue Quyu Prescription orally(a formula with the actions of cooling blood and removing stasis,and composed of Ilicis Pubescentis Radix,Paeoniae Radix Rubra,Moutan Cortex,Rehmanniae Radix,Achyranthis Bidentatae Radix,Jujubae Fructus,and Glycyrrhizae Radix et Rhizoma),and external washing with Shujin Xi External Washing Granules(mainly composed of Clematidis Radix et Rhizoma,Sappan Lignum,Artemisiae Anomalae Herba,Uncariae Ramulus cum Uncis,and Glechomae Herba,and others.The treatment period for both groups lasted for one week.Before and after treatment,the changes in Visual Analogue Scale(VAS)scores of pain,ankle swelling scores,ankle range of motion(including plantar flexion and dorsiflexion),and the American Orthopedic Foot&Ankle Society(AOFAS)ankle-hindfoot scale scores in the two groups were observed.After treatment,the clinical efficacy of the two groups was evaluated.Results(1)After one week of treatment,the total effective rate in the observation group was 95.45%(42/44),and that in the control group was 86.36%(38/44).The intergroup comparison by chi-square test showed that the efficacy of the observation group was significantly superior to that of the control group(P＜0.05).(2)After treatment,the VAS scores for pain in both groups were significantly reduced(P＜0.05)and the AOFAS scores for ankle function were significantly increased(P＜0.05)compared to those before treatment.The observation group showed significant reduction in VAS scores and obvious improvement in AOFAS scores compared to the control group(P＜0.05 or P＜0.01).(3)After treatment,the ankle swelling scores in both groups were significantly reduced(P＜0.05)and the ankle range of motion was significantly improved(P＜0.05)compared to those before treatment.The observation group showed significant reduction in ankle swelling scores and obvious improvement in the range of motion compared to the control group(P＜0.05 or P＜0.01).(4)After treatment,the scores for TCM symptoms of pain,ecchymosis and swelling,and scores of functional disorders in both groups were significantly reduced(P＜0.05)compared to those before treatment.The observation group showed significant reduction in pain,ecchymosis,and swelling scores compared to the control group(P＜0.01),while there was no significant difference in dysfunction scores between the two groups after treatment(P＞0.05).Conclusion The method of cooling blood and removing stasis has significant effects on improving swelling and pain symptoms during the early treatment of acute ankle sprains.It is effective on relieving swelling and pain,and is helpful for promoting the recovery of ankle joint function.

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.

Nonunion of osteoporotic vertebral fractures (OVF), predominantly affecting the elderly, can lead to intractable pain, vertebral collapse, progressive kyphotic deformity, and neurological impairment, significantly compromising patients′ quality of life. There exists considerable debate on diagnosis and management of OVF, encompassing key issues such as clinical diagnosis and staging criteria for nonunion, surgical indications and procedure selection, and postoperative rehabilitation planning. Currently, there lacks standardized clinical guideline and expert consensus on the diagnosis and management of OVF nonunion in China. To address this gap, Minimally Invasive Surgery Group of Chinese Orthopedic Association, Osteoporosis Committee of Chinese Association of Orthopedic Surgeons, Prevention and Rehabilitation Committee for Osteoporosis of Chinese Association of Rehabilitation Medicine and Minimally Invasive Orthopedic Surgery Branch of China Association for Geriatric Care jointly organized domestic experts in spinal surgery, endocrinology, and rehabilitation to formulate the Clinical guideline for the diagnosis and treatment for nonunion of osteoporotic vertebral fractures ( version 2025), based on existing literature and clinical experience and adhering to principles of scientific rigor and practicality. The guideline provided 13 evidence-based recommendations encompassing diagnosis and treatment of OVF nonunion, aiming to standardize its clinical management.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

Objective:To analyze the genetic characteristics of the prevalent strains of Varicella-Zoster virus (VZV) in the population of Dali, Yunnan, and to understand its evolutionary status in the population of Dali.Methods:Herpes fluid and 163 sera were collected from 249 patients clinically suspected to have varicella or herpes zoster in the Department of Dermatology of the Second People′s Hospital of Dali city, Yunnan province, China, from 2023 to 2024. The levels of VZV-specific IgG and IgM antibodies in serum were detected using enzyme-linked immunoassay. Viral DNA was extracted from the herpes fluid, and the cycle threshold ( Ct) of the samples was detected using quantitative real-time polymerase chain reaction (qPCR), and some samples with Ct ≦ 22 were selected for sequencing by next-generation sequencing technology (next-generation sequencing). Next-generation sequencing (NGS) was used to obtain 90 whole genome sequences of VZV, and the sequencing result were compared with the sequences of reference strains for multiple sequence comparison and evolutionary analysis. Snapgene was used to translate the nucleotides into amino acids, and the result were compared with the amino acid sequences of the reference strain. Results:Of the 90 VZV whole-genome sequences, one whole-genome sequence was from an adult varicella patient, and the remaining 89 whole-genome sequences were from herpes zoster patients. The serum-specific IgG antibody positivity rate was 99.4%, and the IgM antibody positivity rate was 52.8%. The result of both single nucleotide polymorphism (SNPs) site typing and genome-wide phylogenetic tree analysis showed that 83 of the 90 VZV whole-genome sequences in this study were on the same branch as Clade 2, and 7 VZV whole-genome sequences were on the branch of Clade 9.Conclusions:The main endemic branch in Dali region in 2023-2024 was Clade 2, with the emergence of Clade 9 branch; there were amino acid mutations in the proteins encoded by ORF22 and ORF68 in 83 VZV whole genome sequences of Clade 2 branch, and the mutations did not cause significant changes to the protein structure.

Objective:To investigate the efficacy and safety of lenvatinib plus drug-eluting bead transarterial chemoembolization (DEB-TACE) and FOLFOX-based hepatic arterial infusion chemotherapy (Len+DEB-TACE+HAIC) versus lenvatinib plus DEB-TACE (Len+DEB-TACE) for hepatocellular carcinoma (HCC) larger than 7 cm with portal vein tumor thrombosis (PVTT).Methods:The data from patients diagnosed with HCC (>7 cm) and PVTT who received either Len+DEB-TACE+HAIC ( n=99) or Len+DEB-TACE ( n=102) between July 2019 and June 2021 at six institutions in China were collected and retrospectively analyzed. Tumor responses were evaluated based on modified Response Evaluation Criteria in Solid Tumors. Objective response rate (ORR), disease control rate (DCR), time to progression (TTP), overall survival (OS), and treatment-related adverse event (TRAE) were compared between the two groups by propensity score matching. Subgroup analyses were performed for TTP and OS. Results:After propensity score matching, 83 pairs of patients were included in the study cohorts. The ORR for the Len+DEB-TACE+HAIC group and the Len+DEB-TACE group was 66.3% and 38.6% ( χ2=12.78, P<0.001), respectively. The DCR for the Len+DEB-TACE+HAIC group and the Len+DEB-TACE group was 91.6% and 79.5% ( χ2=4.87, P=0.027), respectively. The median TTP and median OS for the Len+DEB-TACE+HAIC group were significantly longer than those for the Len+DEB-TACE group (TTP, 10.1 months vs. 6.1 months, χ2=35.28, P<0.001; OS, 17.3 months vs. 12.9 months, χ2=16.84, P<0.001). The incidence of ≥grade 3 TRAEs was 38.6% in the Len+DEB-TACE+HAIC group and 33.7% in the Len+DEB-TACE group ( χ2=0.42, P=0.518). Conclusion:Compared with Len+DEB-TACE, Len+DEB-TACE+HAIC led to improved tumor response, TTP and OS with an acceptable safety profile in patients with large HCC and PVTT.
