OBJECTIVE: To evaluate the safety and clinical therapeutic effect of in-line mechanical in-exsufflation to assist sputum clearance in patients with invasive mechanical ventilation. METHODS: A prospective observational study was conducted at the department of critical care medicine, the First Affiliated Hospital of Sun Yat-sen University from April 2022 to May 2023. Patients who were invasively ventilated and treated with in-line mechanical in-exsufflation to assist sputum clearance were enrolled. Baseline data were collected. Sputum viscosity, oxygenation index, parameters of ventilatory function and respiratory mechanics, clinical pulmonary infection score (CPIS) and vital signs before and after day 1, 2, 3, 5, 7 of use of the in-line mechanical in-exsufflation were assessed and recorded. Statistical analyses were performed by using generalized estimating equation (GEE). RESULTS: A total of 13 invasively ventilated patients using in-line mechanical in-exsufflation were included, all of whom were male and had respiratory failure, with the main cause being cervical spinal cord injury/high-level paraplegia (38.46%). Before the use of the in-line mechanical in-exsufflation, the proportion of patients with sputum viscosity of grade III was 38.46% (5/13) and decreased to 22.22% (2/9) 7 days after treatment with in-line mechanical in-exsufflation. With the prolonged use of the in-line mechanical in-exsufflation, the patients' CPIS scores tended to decrease significantly, with a mean decrease of 0.5 points per day (P < 0.01). Oxygenation improved significantly, with the oxygenation index (PaO₂/FiO₂) increasing by a mean of 23.3 mmHg (1 mmHg ≈ 0.133 kPa) per day and the arterial partial pressure of oxygen increasing by a mean of 12.6 mmHg per day (both P < 0.01). Compared to baseline, the respiratory mechanics of the patients improved significantly 7 days after in-line mechanical in-exsufflation use, with a significant increase in the compliance of respiratory system (Cst) [mL/cmH₂O (1 cmH₂O ≈ 0.098 kPa): 55.6 (50.0, 58.0) vs. 40.9 (37.5, 50.0), P < 0.01], and both the airway resistance and driving pressure (DP) were significantly decreased [airway resistance (cmH₂O×L^-1×s^-1): 9.6 (6.9, 10.5) vs. 12.0 (10.0, 13.0), DP (cmH₂O): 9.0 (9.0, 12.0) vs. 11.0 (10.0, 15.0), both P < 0.01]. At the same time, no new lung collapse was observed during the treatment period. No significant discomfort was reported by patients, and there were no substantial changes in heart rate, systolic blood pressure, diastolic blood pressure, and mean arterial pressure before and after the in-line mechanical in-exsufflation treatment. CONCLUSIONS The combined use of the in-line mechanical in-exsufflation to assist sputum clearance in patients on invasive mechanical ventilation can effectively improve sputum characteristics, oxygenation and respiratory mechanics. The in-line mechanical in-exsufflation was well tolerated by the patients, with no treatment-related adverse events, which demonstrated its effectiveness and safety.

Functional dyspepsia (FD), characterized by persistent or recurrent dyspeptic symptoms without identifiable organic, systemic or metabolic causes, is an increasingly recognized global health issue. The objective of this guideline is to equip clinicians and nursing professionals with evidence-based strategies for the management and treatment of adult patients with FD using traditional Chinese medicine (TCM). The Guideline Development Group consulted existing TCM consensus documents on FD and convened a panel of 35 clinicians to generate initial clinical queries. To address these queries, a systematic literature search was conducted across PubMed, EMBASE, the Cochrane Library, China National Knowledge Infrastructure (CNKI), VIP Database, China Biology Medicine (SinoMed) Database, Wanfang Database, Traditional Medicine Research Data Expanded (TMRDE), and the Traditional Chinese Medical Literature Analysis and Retrieval System (TCMLARS). The evidence from the literature was critically appraised using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach. The strength of the recommendations was ascertained through a consensus-building process involving TCM and allopathic medicine experts, methodologists, pharmacologists, nursing specialists, and health economists, leveraging their collective expertise and empirical knowledge. The guideline comprises a total of 43 evidence-informed recommendations that span a range of clinical aspects, including the pathogenesis according to TCM, diagnostic approaches, therapeutic interventions, efficacy assessments, and prognostic considerations.

the quadriceps muscle tissue.

Objective:To explore the deubiquitination modification of the deubiquitinase BRCC3 in rats with neuropathic pain (NPP) treated with meridian tuina of Zhuang medicine and its analgesic molecular mechanism.Methods:Rats were divided into normal group, sham-operation group, model group, sham-tuina group, and meridian tuina of Zhuang medicine group using a random number table method, with 9 rats in each group. Except for the normal and sham operation groups, spinal nerve ligation models were prepared in all other groups. On the first day after surgery, intervention was carried out on the meridian tuina of Zhuang medicine and sham-tuina groups for 14 days, while the other three groups were not intervened; the paw withdrawal mechanical threshold (PWMT) and paw withdrawal thermal latency (PWTL) of each group of rats were measured at 0 days before operation, 1, 7, and 14 days after operation. Western blot was used to detect the expressions of BRCC3 and NLRP3 proteins in spinal cord tissue, and ELISA was used to detect the level of IL-1β in serum.Results:On postoperative 7 and 14 d, compared with the model group, the meridian tuina of Zhuang medicine group showed an increase in PWMT and PWTL, a decrease in NLPR3 and BRCC3 expression in spinal cord tissue, and a decrease in serum IL-1β levels ( P<0.05). Compared with the sham-tuina group, the meridian tuina of Zhuang medicine group showed an increase in PWMT and PWTL, a decrease in NLRP3 protein expression in spinal cord tissue, and a decrease in IL-1β levels in serum ( P<0.05). Conclusion:Meridian tuina of Zhuang medicine can alleviate pain sensitivity in SNL model rats, and its mechanism is related to the inhibition of the expression of deubiquitinase BRCC3 by meridian massage of Zhuang medicine, which increases the ubiquitination level of NLRP3 and hinders its activation, thereby blocking the immune inflammatory response mediated by inflammatory factors.

Objective: To investigate the effects and mechanisms of Astragalus Polysacharin(APS) on the proliferation and metastasis of breast cancer cells by regulating miR-107 and miR-346-mediated macrophage polarization in breast cancer-derived exosomes. Methods: Forty 8-week-old female BALB/c mice were selected and breast cancer xenograft models and 4T1 transplanted tumor models were established. The mice were divided into the control group and the APS group. The APS group mice received daily intragastric administration of APS for 25 days, while the control group mice were given the same amount of normal saline. After all treatments were completed, the mice were euthanized, and tumor tissues were isolated. Western blot and flow cytometry were used to detect the expressions of proliferating cell nuclear antigen(PCNA), Ki-67, CD206, CD163, inducible nitric-oxide synthase(iNOS), and CD86. The apoptosis of single-cell suspensions in tumor tissues was analyzed. Human breast cancer cell line MDA-MB-231 was cultured and stimulated with APS, and exosomes from the cell culture medium were collected. The proliferation, migration, and invasion of cells were detected by CCK-8 assay, scratch assay, permeability chamber cell invasion assay, and qRT-PCR. Differentially expressed genes were screened by bioinformatics. Results : By measuring the expressions of molecules related to breast cancer cell proliferation and metastasis, it was shown that APS treatment reduced the expressions of proliferation-related proteins(PCNA and Ki-67) and metastasis-related proteins(Vimentin) in MDA-MB-231 xenograft tumor tissues; and the polarization of tumor-associated macrophages was observed. APS treatment of 4T1 transplanted tumor tissues could reduce the number of M2 macrophages and increase the number of M1 macrophages, resulting in a decrease in the ratio of M2/M1 macrophages and an increase in cell apoptosis in 4T1 transplanted tumor tissues. The expressions of related proteins iNOS and CD86 increased, and CD206 and CD163 decreased. After APS treatment, the exosomes produced by MDA-MB-231 reduced the polarization of M2 macrophages and affected the expressions of miR-107 and miR-346. Conclusion APS inhibits the polarization of M2 macrophages by regulating the expression of miR-107 or miR-346 in breast cancer cell-derived exosomes, ultimately inhibiting the proliferation and metastasis of breast cancer cells.

[Objective]To analyze the current research status and hot topics of traditional Chinese medicine(TCM)in the treatment of multiple sclerosis(MS),and provide references for clinical decision-making,future research and the construction of integrated Chinese and western medicine treatment guidelines.[Methods]Relevant literature published from January 2004 to November 2024 was retrieved from the CNKI,VIP,Wanfang,PubMed and Web of Science(WOS)databases.Using CiteSpace 6.3.R1 software,a visual analysis was performed on publication time,authors,institutions and keywords through co-occurrence,clustering and burst analysis to derive the current research status and hot topics.[Results]A total of 168 articles were included.The number of publications in the field of TCM treatment for MS remained relatively stable in recent years,but the proportion of high-quality clinical studies increased.A stable core group of authors was not yet formed,and research institutions were concentrated in major university-affiliated hospitals and traditional Chinese medicine institutions.High-frequency and high-centrality keywords included syndrome differentiation and treatment,renowned physician experience,integrative Chinese and western medicine,etiology and pathogenesis,and TCM syndromes.[Conclusion]TCM treatment for MS is still in the development stage,with a focus on research related to etiology,pathogenesis and syndrome differentiation.Future efforts should emphasize team and institutional collaborations,development of multi-center networks,improvement of research quality,and exploration of interdisciplinary and multi-modal treatment approaches.High-quality evidence-based research should be promoted to inform clinical decision-making,improve treatment protocols,and contribute to the development of integrated Chinese and western medicine treatment guidelines.

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.

Objective:To investigate the effects of chronic persistent hypoxia on hepatic function, histological morphology, and ultrastructure in aged mice, and to evaluate the protective role of pyrroloquinoline quinone(PQQ).Methods:Thirty-two 2-month-old (young group)and thirty-two 18-month-old(aged group)male C57BL6/J mice were each randomly divided into four groups (n=8 per group): normoxia+ normal saline (NS)group, normoxia+ PQQ group, hypoxia+ NS group, and hypoxia+ PQQ group.The normoxia+ NS and normoxia+ PQQ groups were housed under normoxic conditions[fraction of inspired oxygen(FiO 2)=21%], while the hypoxia+ NS and hypoxia+ PQQ groups were continuously exposed to a hypoxic environment[FiO 2=(10±0.5)%]simulated by a custom-made hypoxic chamber, maintaining a constant oxygen concentration for 24 hours per day.The normoxia+ NS and hypoxia+ NS groups received daily intragastric administration of NS, whereas the normoxia+ PQQ and hypoxia+ PQQ groups received daily intragastric administration of PQQ disodium salt(8 mg·kg -1·d -1).After 8 weeks of continuous intervention, blood samples were collected to measure red blood cell count, hemoglobin levels, and liver function-related biochemical indicators.Lung tissues were processed for HE staining, and liver tissues were processed for both HE staining and electron microscopy.The histological and ultrastructural features of each group were observed under light and electron microscopy, respectively, and the differences between the groups were compared and analyzed. Results:Compared with the normoxia+ NS groups, both young and aged hypoxia+ NS groups exhibited significant pulmonary arteriole narrowing( P<0.001), with markedly elevated red blood cell count and hemoglobin levels (all P<0.001), which were not alleviated by PQQ.Compared with the young normoxia+ NS group, the young hypoxia+ NS group showed significantly higher alanine aminotransferase (ALT)and lactate dehydrogenase (LDH)levels( Z=2.72, 2.53, P=0.007, 0.011), whereas the young hypoxia+ PQQ group exhibited LDH levels similar to those of the young normoxia+ NS group.The aged hypoxia+ NS group exhibited significant ALT elevation( t=2.66, P=0.013)compared with the aged normoxia+ NS group.Light microscopy revealed hepatocyte ballooning degeneration, mild fatty accumulation, and focal necrosis around central veins in the young hypoxia+ NS group, while the young hypoxia+ PQQ group exhibited no significant pathological damage but displayed numerous deeply stained binucleated hepatocytes.The aged normoxia+ NS group demonstrated hepatocyte ballooning degeneration and inflammatory cell infiltration around central veins, whereas the aged normoxia+ PQQ group exhibited no obvious pathological damage with scattered deeply stained binucleated hepatocytes.The aged hypoxia+ NS group exhibited significant necrosis following physiological oxygen concentration gradient distribution, while the aged hypoxia+ PQQ group displayed no obvious pathological damage with scattered deeply stained binucleated hepatocytes.Electron microscopy revealed that the aged normoxia+ NS group had reduced mitochondrial electron density ( P<0.001)and less developed rough endoplasmic reticulum compared with the young normoxia+ NS group.The young hypoxia+ NS group exhibited a smaller mitochondrial area( P<0.001), decreased mitochondrial matrix electron density( P<0.001), blurred or absent mitochondrial cristae, inactive rough endoplasmic reticulum, and increased accumulation of glycogen and lipid droplets compared with the young normoxia+ NS group, while the young hypoxia+ PQQ group maintained mitochondrial matrix electron density comparable to the young normoxia+ NS group.The aged hypoxia+ NS group exhibited larger mitochondrial area( P=0.001), decreased mitochondrial matrix electron density( P<0.001), blurred or absent mitochondrial cristae, mitochondrial edema, increased lysosomes, and elevated cytoplasmic electron density compared with the aged normoxia+ NS group.The aged hypoxia+ PQQ group exhibited reduced mitochondrial area( P<0.001)and restored mitochondrial matrix electron density to levels comparable with the aged normoxia+ NS group.The aged normoxia+ PQQ group demonstrated increased mitochondrial matrix electron density compared with the aged normoxia+ NS group( P<0.001). Conclusions:Chronic persistent hypoxia induces hepatic functional, histological and ultrastructural damage in mice, with more pronounced effects in aged animals.PQQ provides a certain degree of protection against these injuries.

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.

Objective:To evaluate the predictive role of ultrasound, genetic testing, and clinical features in the malignancy risk of Bethesda Ⅲ thyroid nodules, and to explore strategies for optimizing treatment decisions.Methods:This retrospective study included 227 Bethesda Ⅲ thyroid nodules from patients who underwent surgical treatment at the Thyroid Surgery Department of Nanjing Drum Tower Hospital between Jan. 2020 and Dec. 2023. All patients underwent ultrasound evaluation and fine-needle aspiration. For nodules diagnosed as ultrasound, genetic testing, and clinical features were analyzed using univariate and multivariate regression to assess their association with malignancy.Results:Among the 227 nodules, 214 were malignant, resulting in a malignancy rate of 94.2%. The malignancy rate of thyroid nodules was 94.2%. In univariate analysis, age ( P=0.016), BRAF V600E gene mutation ( P<0.001), nodule size ( P=0.002), and TIRADS ( P<0.001) were significantly associated with malignancy in Bethesda Ⅲ thyroid nodules. Multivariate analysis confirmed that age ( OR=0.939, P=0.049) and BRAF V600E gene mutation ( OR=24.641, P<0.001) were significantly associated with thyroid nodule nature and served as independent predictive factors for malignancy. Conclusions:Genetic testing is an important method for predicting the malignancy of Bethesda Ⅲ thyroid nodules, and ultrasound also has high clinical value in assessing the malignancy risk of nodules. While some clinical features are highly correlated with nodule characteristics, they may not be practical in clinical application. For nodules classified as TIRADS 3 through ultrasound evaluation and negative for BRAF mutations, continued observation may be considered, whereas TIRADS 5 nodules or nodules with BRAF mutations should be prioritized for surgical treatment.
