BACKGROUND:Changes in skeletal muscle mass have been indicated in studies addressing the effects of low-frequency pulsed magnetic fields on the structure and morphology of the skeletal muscle,but no relevant studies have been conducted on the morphologic changes that occur after chronic exposure to the low-frequency pulsed magnetic field. OBJECTIVE:To observe the effects of chronic exposure to low-frequency pulsed magnetic fields on the maximal voluntary contraction and morphologic indicators of the quadriceps muscle of the leg,thereby providing a reference of muscle morphologic changes for the use of this technique as a strategy for muscle function improvement. METHODS:Seventy healthy subjects were recruited and randomly divided into a test group that received magnetic field stimulation and a control group that underwent sham treatment,with 35 subjects in each group,and the total duration of the trial was 4 weeks.The test group underwent low-frequency pulsed magnetic stimulation for 15 minutes every 48 hours,while the control group underwent sham treatment,with the same intervention interval and duration as the test group.After 4 weeks of intervention,changes in the maximum voluntary contraction value of the quadriceps muscle in different groups were observed,and B-mode ultrasonography was utilized as a means of assessment to observe changes in muscle thickness,muscle cross-sectional area,and pinnation angle indexes. RESULTS AND CONCLUSION:After 4 weeks of chronic exposure to low-frequency pulsed magnetic fields,68 subjects completed the test.The maximum voluntary contraction value of the quadriceps muscle in the test group increased significantly(P=0.000),and the increment was significantly higher than that of the control group(P=0.008).Three indexes related to muscle morphology in the test group were significantly higher than the pre-test values(P=0.000),while in the control group,muscle thickness showed a significant reduction(P=0.020),there was no significant change in the pinnation angle,but a significant increase in the cross-sectional area(P=0.000).Intergroup comparisons revealed that the three indicators related to muscle morphology,including muscle thickness(P=0.012),pinnation angle(P=0.003),and cross-sectional area(P=0.049),were significantly higher in the test group than in the control group.The above data confirmed that the maximum voluntary contraction of the quadriceps muscle was significantly increased in healthy adults after 4 weeks of chronic exposure to the low-frequency pulsed magnetic field,and significant increases in the three muscle morphometric indices of muscle thickness,cross-sectional area,and pinnation angle were observed in the test group,providing a basis of muscle tissue morphology for the use of this technique as an exercise alternative and medical treatment strategy for muscle improvement.

With the continuous intensification of aging, chronic diseases among the elderly have become a widely concerned public health issue. In the terminal stage, they often lose the ability to express their medical care wishes autonomously, leading to a disconnect between medical decision-making and the actual needs of the patients and increasing their physical and psychological suffering. With the rapid aging process in China, the incidence of chronic diseases in the elderly is continuously rising, which has become a serious public health problem. Studies have shown that advance care planning (ACP) has achieved remarkable results in maintaining the dignity of life for terminal chronic disease patients, improving patients’ quality of life, as well as alleviating the physical, mental, and economic burdens on their families. Therefore, the implementation of ACP is crucial for elderly patients with chronic diseases. This paper reviewed the concept of ACP, as well as application effects, challenges and limitations, and corresponding recommendations and countermeasures of ACP in elderly patients with chronic diseases, with a view to providing a solid theoretical and practical basis for the application of ACP in elderly population with chronic diseases in China.

To investigate the incidence of postoperative neuropsychic dysfunction (PND) in Parkinson's disease (PD) patients undergoing deep brain stimulation (DBS) and to analyze its influencing factors. A prospective study was conducted between January 2020 and December 2022, recruiting PD patients from the Functional Neurosurgery Outpatient Clinic of Beijing Tiantan Hospital, Capital Medical University. All patients were scheduled to undergo bilateral subthalamic nucleus (STN)-DBS surgery. Perioperative clinical data were collected, and PND (outcome measure) within 3 days postoperatively was assessed using the Montreal cognitive assessment (MoCA), mini-mental state examination (MMSE), Hamilton depression and anxiety scales, and 3-minute diagnostic interview for confusion assessment method (3D-CAM). Multivariate Logistic regression was used to analyze the influencing factors of PND. A total of 216 PD patients were enrolled. Within 3 days after DBS surgery, 77 patients (35.6%) developed PND, including 24 cases (31.2%) of depression or worsening depression, 16 cases (20.8%) of anxiety or worsening anxiety, 13 cases (16.9%) of cognitive decline, and 24 cases (31.2%) of delirium. Univariate analysis revealed that dural opening method, dural opening time, intraoperative improvement rate of the unified Parkinson's disease rating scale -Ⅲ (UPDRS-Ⅲ) score, and postoperative intracranial air volume were significantly different between PND and non-PND patients (all PD patients have a high incidence of PND after DBS surgery. Sex, postoperative intracranial air volume, and the degree of improvement in PD motor symptoms can influence the risk of PND. These findings highlight the importance of individualized management based on sex, improving surgical techniques, and enhancing monitoring of neuropsychiatric status to optimize the efficacy of DBS surgery.

Biomolecular condensates are formed through phase separation of biomacromolecules such as proteins and RNAs. These condensates exhibit liquid-like properties that can futher transition into more stable material states. They form complex internal structures via multivalent weak interactions, enabling precise spatiotemporal regulations. However, the use of inconsistent and non-standardized terminology has become increasingly problematic, hindering academic exchange and the dissemination of scientific knowledge. Therefore, it is necessary to discuss the terminology related to biomolecular condensates in order to clarify concepts, promote interdisciplinary cooperation, enhance research efficiency, and support the healthy development of this field.

Hepatitis B virus (HBV) infection is a global public health issue, affecting the health of 250 million people worldwide. Despite the significant progress in antiviral therapy for HBV, some patients still experience low-level viremia (LLV) after receiving antiviral therapy and fail to achieve viral clearance, with an HBV DNA load remaining at a relatively low level of 20 — 2 000 IU/mL. LLV is often caused by multiple factors such as the high stability of the virus, the difficulty in clearing the virus with antiviral drugs, host immune factors, and drug resistance, which increase the difficulties in antiviral therapy. In addition, LLV can also cause liver damage, which may eventually progress to severe outcomes such as hepatocellular carcinoma. This article reviews LLV in hepatitis B in terms of diagnosis, influencing factors, clinical significance, and treatment strategies.

The liver has diverse functions such as metabolism, detoxification, and immune defense, and the maintenance of hepatic microenvironment homeostasis is crucial for overall bodily health. The hepatic microenvironment consists of the components such as parenchymal cells, non-parenchymal cells, and non-cellular components. Chronic inflammatory responses induced by various etiological factors may promote the formation and progression of liver fibrosis. During the dynamic progression of liver fibrosis, from the early to advanced stages, various components within the hepatic microenvironment undergo a series of changes, which can promote the malignant progression of liver fibrosis. An in-depth exploration of the mechanisms underlying such changes in each component of the liver fibrosis microenvironment is of great significance for understanding the pathogenesis of liver fibrosis and discovering potential treatment strategies.

ObjectiveTo construct a large language model (LLM)-based intelligent pre-consultation system for traditional Chinese medicine (TCM) to improve efficacy of clinical practice. MethodsA TCM large language model was fine-tuned using DeepSpeed ZeRO-3 distributed training strategy based on YAYI 2-30B. A weighted undirected graph network was designed and an agent-based syndrome differentiation model was established based on relationship data extracted from TCM literature and clinical records. An agent collaboration framework was developed to integrate the TCM LLM with the syndrome differentiation model. Model performance was comprehensively evaluated by Loss function, BLEU-4, and ROUGE-L metrics, through which training convergence, text generation quality, and language understanding capability were assessed. Professional knowledge test sets were developed to evaluate system proficiency in TCM physician licensure content, TCM pharmacist licensure content, TCM symptom terminology recognition, and meridian identification. Clinical tests were conducted to compare the system with attending physicians in terms of diagnostic accuracy, consultation rounds, and consultation duration. ResultsAfter 100 000 iterations, the training loss value was gradually stabilized at about 0.7±0.08, indicating that the TCM-LLM has been trained and has good generalization ability. The TCM-LLM scored 0.38 in BLEU-4 and 0.62 in ROUGE-L, suggesting that its natural language processing ability meets the standard. We obtained 2715 symptom terms, 505 relationships between diseases and syndromes, 1011 relationships between diseases and main symptoms, and 1 303 600 relationships among different symptoms, and constructed the Agent of syndrome differentiation model. The accuracy rates in the simulated tests for TCM practitioners, licensed pharmacists of Chinese materia medica, recognition of TCM symptom terminology, and meridian recognition were 94.09%, 78.00%, 87.50%, and 68.80%, respectively. In clinical tests, the syndrome differentiation accuracy of the system reached 88.33%, with fewer consultation rounds and shorter consultation time compared to the attending physicians (P<0.01), suggesting that the system has a certain pre- consultation ability. ConclusionThe LLM-based intelligent TCM pre-diagnosis system could simulate diagnostic thinking of TCM physicians to a certain extent. After understanding the patients' natural language, it collects all the patient's symptom through guided questioning, thereby enhancing the diagnostic and treatment efficiency of physicians as well as the consultation experience of the patients.

OBJECTIVE To investigate the clinical efficacy of integrating pharmacists into family health teams (FHTs) for long-term medication therapeutical management (MTM) in stroke patients, and empirically evaluate the service model. METHODS A pharmacist team, jointly established by clinical and community pharmacists from the Affiliated Suzhou Hospital of Nanjing Medical University (hereinafter referred to as “our hospital”), developed a pharmacist-supported MTM model integrated into FHTs. Using a prospective randomized controlled design, 170 stroke patients discharged from our hospital (July 2022-December 2023) and enrolled in FHTs at Suzhou Runda Community Hospital were randomly divided into trial group (88 cases) and control group (82 cases) according to random number table. The control group received routine FHTs care (without pharmacist involvement in the team collaboration), while the trial group xhz8405@126.com received 12-month MTM services supported by pharmacists via an information platform. These services specifically included innovative interventions such as personalized medication regimen optimization based on the MTM framework, dynamic medication adherence management, medication safety monitoring, a home medication assessment system, and distinctive service offerings. Outcomes of the 2 grousp were compared before and after intervention, involving medication adherence (adherence rate, adherence score), compliance rates for stroke recurrence risk factors [blood pressure, low-density lipoprotein cholesterol (LDL-C)], and incidence of adverse drug reactions (ADR). RESULTS After 12 months, the trial group exhibited significantly higher medication adherence rates, improved adherence scores, higher compliance rates for blood pressure and LDL-C targets compared to the control group (P<0.05). The incidence of ADR in the trial group (4.55%) was significantly lower than that in the control group (8.11%), though the difference was not statistically significant (P> 0.05). CONCLUSIONS Pharmacist involvement in FHTs to deliver MTM services significantly enhances medication adherence and optimizes risk factor for stroke recurrence, offering practical evidence for advancing pharmaceutical care in chronic disease management under the family doctor system.

AIM:To evaluate the clinical efficacy of 0.05% cyclosporine eye drops(Ⅱ)combined with sodium hyaluronate eye drops in treating patients with type 2 diabetes mellitus(T2DM)and moderate-to-severe dry eye.METHODS:A total of 120 T2DM patients(120 eyes)with moderate-to-severe dry eye, treated at the endocrinology and ophthalmology departments at the Affiliated Hospital of Xuzhou Medical University from January 2024 to September 2024, were enrolled in the study. The patients were randomly divided into two groups: combination group [0.05% cyclosporine eye drops(Ⅱ)+ sodium hyaluronate eye drops] and control group(sodium hyaluronate eye drops alone), with 60 cases(60 eyes)in each group. Assessments were conducted at baseline and at 1, 2, and 3 mo post-treatment, including the ocular surface disease index(OSDI), non-contact tear meniscus height(NITMH), first non-invasive tear breakup time(NIBUTf), meibomian gland loss score, lipid layer thickness grade, conjunctival hyperemia grade, and corneal fluorescein staining(FL)score. At 3 mo after treatment, changes in tear inflammatory factors were observed, and corneal subbasal nerve plexus(SBN)morphology/density were analyzed using in vivo confocal microscopy(IVCM).RESULTS:At 1, 2, and 3 mo post-treatment, both groups showed statistically significant increases in NITMH and NIBUTf compared to baseline(all P<0.05), with greater improvement observed in the combination group(both P<0.05). OSDI and FL scores significantly decreased from baseline(all P<0.05), with more pronounced reductions in the combination group(both P<0.05). Meibomian gland loss scores showed no significant improvement in either group(all P>0.05). At 3 mo after treatment, tear levels of interleukin 6(IL-6)and matrix metalloproteinase-9(MMP-9)significantly decreased in both groups(all P<0.001), with a greater reduction noted in the combination group(both P<0.001). The combination group displayed increased corneal nerve branch density and nerve fiber density, along with decreased nerve tortuosity and dendritic cell(DC)density compared to baseline(all P<0.001), while the control group did not show significant changes(all P>0.05).CONCLUSION: The combination of 0.05% cyclosporine eye drops(Ⅱ)and sodium hyaluronate eye drops significantly improves clinical outcomes in T2DM patients with moderate-to-severe dry eye. This treatment effectively alleviates ocular surface inflammation, restores corneal nerve morphology and density, and demonstrates a favorable safety profile.

AIM: To explore the risk factors associated with diabetic retinopathy(DR)based on ultra-widefield swept-source optical coherence tomography angiography(UWF-SS-OCTA), and to establish a clinical prediction model.METHODS:A total of 235 patients(235 eyes)with type 2 diabetes mellitus who were treated in the Affiliated Hospital of Xuzhou Medical University from July to November 2024 were selected as the research objects. According to the presence or absence of DR, they were divided into 120 cases(120 eyes)in non-DR group(NDR group)and 115 cases(115 eyes)in non-proliferative DR group(NPDR group). Data on general characteristics, laboratory tests, and OCTA results were collected for both groups. Univariate analysis was employed to identify DR-related risk factors. Logistic regression analysis was conducted to analyze these risk factors and to establish a DR prediction model. The efficacy of the model was evaluated using the receiver operating characteristic(ROC)curve, calibration curve, and decision curve analysis(DCA).RESULTS: The duration of diabetes, fasting blood glucose, blood urea nitrogen(BUN), history of hypertension, and the choroidal vascular index(CVI)were found to be statistically significant in the model(all P<0.05). Specifically, the duration of diabetes, fasting blood glucose, BUN, and history of hypertension were identified as risk factors for DR among diabetic patients, while CVI was recognized as a protective factor. The area under the curve for the model predicting the probability of DR was 0.898(0.859-0.938), with a diagnostic threshold of 0.438. The corresponding sensitivity and specificity were 87.8% and 78.3%, respectively, indicating that the model possesses high predictive value for the occurrence of DR.CONCLUSION: The duration of diabetes, fasting blood glucose, BUN, history of hypertension, and CVI are significantly correlated with DR. The established prediction model demonstrates a substantial screening capability for DR.
