ObjectiveTo evaluate the effectiveness of stone needle thermocompression and massage compared to flurbiprofen gel patch in relieving chronic musculoskeletal pain in the shoulder and back， and to explore the potential mediating mechanism through muscle elasticity. MethodsA total of 120 patients with chronic musculoskeletal pain in the shoulder and back were randomly assigned to either stone needle group or flurbiprofen group， with 60 patients in each. The stone needle group received stone needle thermocompression and massage for 30 minutes， three times per week； the flurbiprofen group received flurbiprofen gel patch twice daily. Both groups were treated for 2 weeks. Pain improvement， as the primary outcome， was assessed using the Global Pain Scale （GPS） at baseline， after 2 weeks of treatment， and again 2 weeks post-treatment. To explore potential mechanisms， a mediator analysis was conducted by measuring changes in superficial and deep muscle elasticity using musculoskeletal ultrasound at baseline and after the 2-week treatment period. ResultsThe stone needle group showed significantly greater pain relief than the flurbiprofen group 2 weeks post-treatment. After adjusting for confounders related to pain duration， the between-group mean difference was -8.8 ［95% CI （-18.2， -0.7）， P＜0.05］. Part of the therapeutic effect was mediated by changes in deep muscle elasticity， with a mediation effect size of -1.5 ［95% CI （-2.0， -0.9）， P = 0.024］， accounting for 17.9% of the total effect. ConclusionStone needle thermocompression and massage can effectively relieve chronic musculoskeletal pain in the shoulder and back， partly through a mediating effect of improved deep muscle elasticity.

Objective: To screen the frequency of CD36 antigen expression in platelet donor database in Shaanxi province and analyze the molecular genetic characteristics of samples with CD36 antigen deficiency and low expression. Methods: A total of 525 platelet donors samples were randomly collected during May 2023. CD36-FITC monoclonal antibody was used for immunofluorescence labeling, and flow cytometry was applied to detect the expression of CD36 antigen on platelets. For samples with CD36 antigen deficiency on platelets, the expression of CD36 on monocytes was further detected. Samples with CD36 antigen deficiency and low expression were sequenced and analyzed. Results: Among the 525 blood samples, 99.24% (521/525) showed positive expression of CD36 antigen. There were differences in the expression intensity of CD36 antigen, with low expression accounting for 3.43% (18/525) and CD36 antigen deficiency accounting for 0.76% (4/525), all of which were type Ⅱ deficiency. The exon mutation frequency of CD36 type Ⅱ deficiency and low expression samples was 31.82% (7/22), and the exon mutation types were 121-1_126delGCAAGTT, 329-330delAC, 1142T>G, 1204-1246dupl 43bp, 1221G>A, and 1228-1239delATTGTGCCTATT. All four cases of CD36 type Ⅱ deficiency had a 121-6 T>C mutation in intron 3. All CD36 low expression samples had a mutation of 282-10A>G, and 121-6T>C mutation rate was 61.1%(11/18). Conclusion: There were differences in the expression of CD36 antigen in the platelet donor database in Shaanxi province, which may be caused by multiple molecular genetic variations. The frequency of CD36 antigen deficiency in Shaanxi was lower than that of Han, Zhuang and Yao populations in southern China. This study provides references for solving the CD36 antibody mediated transfusion reaction and auxiliary treatment of diseases caused by CD36 antigen deficiency in the future. It also provides a basis for investigating the molecular mechanisms of CD36 deficiency and low expression.

Background The decline of physical activity in the elderly due to aging may increase the risk of sarcopenia. Currently, there is a lack of evidence from large natural populations on the relationship between PA and sarcopenia. Objective To explore the relationship between PA and sarcopenia in the elderly aged 60 years and above in 10 provinces (autonomous regions) of China. Methods Data were retrieved from the 2022—2023 round of the China Development and Nutrition Health Impact Cohort. Personal basic information and PA data were collected by questionnaire survey. Skeletal muscle mass was measured by bio-electrical impedance analysis, muscle strength was measured using a grip dynamometer, and physical performance was reflected by 6-meter walk speed. The Asian Working Group for Sarcopenia (AWGS) 2019 criteria were used to diagnose sarcopenia. Light physical activity (LPA) duration, moderate-to-vigorous physical activity (MVPA) duration, and total physical activity volume were calculated. A total of 3326 residents aged ≥60 years with complete data were selected as the survey participants. Multiple logistic regression models and restricted cubic splines (RCS) were used to assess the association between PA duration/volume and sarcopenia. Results In 10 provinces (autonomous regions) of China, the prevalence of sarcopenia in the elderly aged 60 years and above was 5.5% (95%CI: 4.7%, 6.2%). The logistic regression analysis showed that compared with the elderly reporting 0-7.0 h·week⁻¹ in LPA duration, the risk of sarcopenia in the elderly with LPA duration of >14.0-21.0 h·week⁻¹ was reduced by 51% (OR=0.49, 95%CI: 0.26, 0.96). Compared with the elderly with total physical activity ≥15.0 metabolic equivalent of task (MET)-h·week⁻¹, those with <7.5 MET-h·week⁻¹ had a 2.24-fold increased risk of sarcopenia (OR=2.24, 95%CI: 1.17, 4.29). The RCS results found that LPA duration and total physical activity volume each showed a nonlinear dose-response relationship with the risk of sarcopenia (P_overall<0.05, P_non-linear<0.05). Compared with the elderly with an LPA duration of 0 h· week⁻¹, the risk of sarcopenia in the elderly with an LPA duration of 12.6 h· week⁻¹ was the lowest (OR=0.42, 95%CI: 0.21, 0.83). Compared with the elderly with a total physical activity volume of 15.0 MET-h· week⁻¹, the elderly with a total physical activity volume of 46.0 MET-h· week⁻¹ had the lowest risk of sarcopenia (OR=0.57, 95%CI: 0.38, 0.84). There was no statistically significant association between weekly MVPA duration and the risk of sarcopenia (P>0.05). Conclusion Increasing weekly LPA duration and total physical activity volume would help to reduce the risk of sarcopenia.

Objective: To investigate the therapeutic effect of patchouli alcohol on mice with lung-heat syndrome based on the phosphoinositide 3-kinase(PI3K)/protein kinase B(Akt)/nuclear factor-kappa B(NF-κB) signaling pathway. Methods: First, network pharmacology was used to predict the potential targets of patchouli alcohol in the treatment of lung-heat syndrome, and a "component-disease-key target" network was constructed for pathway analysis. Then, 40 BALB/c mice were assigned to the normal, lung-heat model, honeysuckle, and low-dose and high-dose patchouli alcohol groups. All groups, except the blank group, were intranasally infected with 50 μL (103 TCID50) of influenza virus solution. After two hours of infection, mice were treated once a day for seven consecutive days. The therapeutic mechanism of patchouli alcohol was explored by measuring pulmonary inflammatory factors, the PI3K/Akt/NF-κB pathway, hypothalamic fever markers (PGE2, cAMP, cGMP levels), rectal temperature, and tissue energy metabolism. Results: Network pharmacology identified 135 target genes related to patchouli alcohol and lung-heat syndrome, with the key targets being STAT3, H1F1A, and NF-κB1. In animal experiments, patchouli alcohol significantly alleviated influenza virus-induced lung inflammatory damage in mice with lung-heat syndrome, inhibited the expression of TNF-α and IL-6 in lung tissues(P<0.01), and suppressed the activation of the PI3K/Akt/NF-κB pathway. It also reduced hypothalamic levels of PGE2 and cAMP(P<0.01), suppressed the increase in rectal temperature, significantly decreased liver glycogen and pyruvate levels(P<0.01), and increased the activities of SDH, LDH, and Na+ -K+ -ATPase in the liver(P<0.01) Conclusion Patchouli alcohol improves the symptoms of lung-heat syndrome in mice by inhibiting the activation of the PI3K/Akt/NF-κB pathway, reducing proinflammatory cytokines and inflammatory damage, and regulating hypothalamic fever markers and energy metabolism.

The rat model of stomach-heat was established by intragastric administration of pepper aqueous solution (0.80 g/kg) and anhydrous ethanol, and the rat model of stomach-cold was established by intragastric administration of water extract of Anemarrhena asphodeloides and sodium hydroxide (10.40 g/kg). On the day of modeling, the rats in the Baked ginger group were given Baked ginger decoction (0.78 g/kg), and the rats in the Coptidis Rhizoma group were given Coptidis Rhizoma decoction (0.43 g/kg).The stomach-cold and stomach-heat low-dose group of carvacrol was given carvacrol emulsion (40 mg/kg), high-dose group was given carvacrol emulsion (80 mg/kg).All rats of the blank and model groups were given the equal volume of emulsion prepared by 5% dimethyl sulfoxide, 1% Tween 80, 1% polyethylene glycol 400, and 93% normal saline, once a day, for 7 days. The general condition of rats was observed and the body mass was recorded. The pathological morphology of gastric tissue was observed by hematoxylin-eosin staining. The changes of material and energy metabolism, cyclic nucleotide (cAMP), thyroid hormone and gastrointestinal hormone in each group were determined by enzyme-linked immunosorbent assay. The expression levels of transient receptor potential vanilloid subtype 1 (TRPV1), transient receptor potential channel M8 (TRPM8) and uncoupling protein-1 (UCP1) in rats with gastric fever were detected by Western blotting. Results: Compared with the stomach-heat blank group, the body mass of rats in the stomach-heat model group decreased at the fifth and seventh day (P<0.05). The contents (or ratio) of hepatic glycogen (HGlyc), total cholesterol (TC), triglyceride (TG), and vasoactive intestinal peptide (VIP) were decreased (P<0.05), and Na+ -K+ -ATPase, Ca2+ -Mg2+ -ATPase, cytochrome C oxidase (COX), NADH dehydrogenase (ND), cyclic adenosine phosphate (cAMP), cAMP/cyclic guanosine phosphate (cGMP), triiodothyronine (T3), thyroxine (T4), gastrin (GAS), motilin (MTL), and α-amylase (α-AMS) all increased (P<0.05). Compared with the stomach-heat model group, the body mass of rats in the Coptidis Rhizoma group decreased at the third, fifth, and seventh day, the contents (or ratio) of HGlyc, TC, TG, VIP and α-AMS were increased, and Na+ -K+ -ATPase, COX, ND, cAMP, cAMP/cGMP, T3, T4, and GAS all decreased (P<0.05). The body mass of rats in the stomach-heat low-dose carvacrol group decreased at the seventh day. The contents (or ratio) of HGlyc, TC, and VIP were increased, Na+ -K+ -ATPase, COX, ND, cAMP, cAMP/cGMP, T3, T4, and MTL all decreased, the expression of TRPV1 and UCP1 in gastric tissue decreased, while TRPM8 increased (P<0.05) in rats of the stomach-heat low-dose and high-dose carvacrol groups. Compared with the stomach-cold blank group, the body mass of rats in the stomach-cold model group decreased at the third, fifth, and seventh day, the contents (or ratio) of HGlyc, TC, TG, α-AMS, and VIP all increased, while Na+ -K+ -ATPase, Ca2+ -Mg2+ -ATPase, COX, ND, cAMP, cAMP/cGMP, T3, T4, GAS, and MTL all decreased (P<0.05). Compared with the stomach-cold model group, the body mass of rats in the Baked ginger group was increased at the seventh day, and the contents (or ratio) of HGlyc, VIP, and α-AMS all decreased, while Na+ -K+ -ATPase, COX, ND, cAMP/cGMP, T3, T4, GAS, and MTL all increased (P<0.05). The contents of HGlyc, cAMP, α-AMS, and VIP of rats in the stomach-cold low and high-dose carvacrol group all decreased (P<0.05). TG in the stomach-cold low-dose carvacrol group was increased. TC, Ca2+ -Mg2+ -ATPase, and cGMP all increased, while cAMP/cGMP decreased (P<0.05) in the high-dose carvacrol group. Conclusion In this study, the rat model of stomach-cold and stomach-heat were successfully established by using cold and heat factors. The result showed that carvacrol had a certain inhibitory effect on body mass, material energy metabolism, cyclic nucleotide level, thyroid hormone and gastrointestinal function in rats with stomach-heat, indicating that the drug was cold. Carvacrol′s cold medicinal property could be biologically explained by TRPV1 activation, UCP1 induction, and TRPM8 suppression.

Objective: To explore the influencing factors for implementation of weight management services in primary medical and healthcare institutions, so as to provide references for implementing sustainable services of weight management. Methods: From May to June 2025, Pinghu City, Zhejiang Province was selected as the survey site. Personnel responsible for weight management in primary medical and healthcare institutions were selected as the survey subjects using a combined method of purposive sampling and snowball sampling. Based on the five core domains of the consolidated framework for implementation research (CFIR), a semi-structured interview outline for weight management services in primary medical and healthcare institutions was designed. Original data was collected through face-to-face semi-structured interviews. Interview data was organized and analyzed using framework analysis. Factors affecting weight management services were quantitatively analyzed by referencing CFIR's structural rating criteria. Results: A total of 21 participants completed interviews, covering positions in nutrition, endocrinology, traditional Chinese medicine, general practice, maternal health, and public health. There were 9 males and 12 females. Fifteen participants (71.43%) were aged 35 years and above, 18 (85.71%) held a bachelor's degree or higher, and 15 (71.43%) were frontline medical staff. Fifteen factors affecting weight management services were identified across five domains: innovation, outer setting, inner setting, individuals, and implementation process. Six barrier factors were identified: difficulties in policy implementation, time-consuming interventions, limited incentive measures, lack of professional skills, unclear weight-loss plans and goal setting, and imperfect follow-up and evaluation mechanisms. Three neutral factors were identified: the development and refinement of policies and regulations, the implementation of weight management training, and the optimization of the referral process within integrated healthcare systems (medical alliances / communities). Six facilitating factors were identified: the relatively significant advantages of lifestyle interventions, collaboration and coordination across multiple departments, cooperative communication among different units within the institution, the inherent convenience of primary care settings, a strong sense of professional responsibility, and the establishment of multidisciplinary teams. Conclusions The delivery of weight management services in primary medical and healthcare institutions is influenced by a wide array of factors across multiple domains. It requires policy support, multi-department coordination, a practice-oriented training system, optimized team resource allocation, incentives, and improved professional skills of medical staff to jointly promote long-term implementation.

Adult-onset leukoencephalopathy with axonal spheroids and pigmented glia(ALSP)is a clinically rare autosomal dominant genetic disease,and its specific pathogenesis is not yet clear.The colony-stimulating factor 1 receptor(CSF1R)is a transmembrane tyrosine kinase receptor on the cell surface and mutations in the gene encoding it have been identified as potential pathogenic factors for ALSP.However,the specific mechanisms by which CSF1R gene mutations lead to the onset of ALSP are still unclear.After reviewing the mutation sites and pathogenic mechanisms of CSF1R in the pathogenesis of ALSP,CSF1R mutations have been shown to cause microglial dysfunction through mechanisms such as dominant-negative effects,loss of function,haploinsufficiency,and gain of function,thereby leading to the onset of ALSP.A deeper understanding of the causes of ALSP will help in exploring potential treatment methods.

Objective:To explore the effect of Jian-Pi-Zhi-Dong decoction on autonomous activity and dopamine (dopamine, DA) synaptic vesicle protein expression in the striatum of Tourette syndrome (TS) model rats.Methods:The 4-week-old male SD rats were used to establish the TS model by intraperitoneal injection of N-aminodipropionate. Thirty successfully modeled rats were randomly divided into model group, Chinese medicine group, and tiberide group according to random number table method, with 10 rats in each group. And another 10 rats with matched body mass were selected as the control group. Rats in Chinese medicine group were given Jian-Pi-Zhi-Dong decoction solution (1.6 g/100 g) and the rats in tiapride group were given sulfate tiapride suspension (2.1 mg/100 g), while rats in control group and model group were given an equal volume of 0.9% sodium chloride solution, once a day for 4 weeks.The number of autonomous activities in rats was determined by autonomous activity programmer. ELISA was used to detect the level of DA in the striatum of rats and the expression of dopamine transporter (DAT).Vesicular monoamine transporter-2 (VMAT2) and α-synuclein (α-syn) were measured by Western blot.SPSS 25.0 software was used for data analysis. Multiple group comparisons were performed using one-way ANOVA, non-parametric test and repeated measures ANOVA.Results:Comparing the number of autonomous activities among the 4 groups, the interaction effect between time and group was significant ( F=184.354, P<0.001). At the 1-4 weeks of gavaging, the numbers of autonomic activities in the model group were more than those in the control group (all P<0.05).While the numbers of autonomic activities in Chinese medicine group and tiapride group were less than those in the model group (all P<0.05). Moreover, the numbers of autonomic activities in Chinese medicine group and tiapride group from 1 to 4 weeks were less than those after model making (all P<0.05). The Western blot results showed significant differences in the relative expression of α-syn ( H=29.098), DAT ( F=54.632) and VMAT2 ( H=18.982) among the 4 groups (all P<0.001). The expression levels of α-syn protein in Chinese medicine group and tiapride group were both lower than that in the model group (0.39(0.36, 0.51), 0.39(0.36, 0.50), 0.62(0.50, 0.70)) (both P<0.05). The expression level of DAT protein in Chinese medicine group was higher than that in the model group and lower than that in tiapride group ((0.37±0.06), (0.26±0.07), (0.49±0.09)) (both P<0.05). And the expression level of VMAT2 protein in Chinese medicine group had no significant difference compared with that in the model group ( P>0.05).The ELISA results showed significant differences in DA content of striatum among the 4 groups ( F=75.370, P<0.001). The level of DA in the model group was higher than that in the control group ((7.65±0.72) ng/L, (3.71±0.59) ng/L, P<0.05). The levels of DA in Chinese medicine group ((3.92±0.81) ng/L) and tiapride group ((4.40±0.53) ng/L) were lower than that in the model group (both P<0.05), and the difference between Chinese medicine group and tiapride group was not significant ( P>0.05). Conclusion:Jian-Pi-Zhi-Dong decoction can relieve the tic symptoms of the model rats with TS, and its mechanism may be related to inhibiting the excessive release of α-syn, improving the expression of DAT and VMAT2, improving the DA synaptic vesicle circulation, and reducing the DA content in the synaptic space of the brain.

Objective Improving the limb management strategy for patients undergoing coronary intervention through radial artery puncture and observe the application effect,and to provide scientific basis for the prevention of limb complications.Methods From March 2023 to February 2024,patients who underwent coronary intervention in the Cardiovascular Department of a Tertiary A hospital in Wenzhou City were selected.They were randomly di-vided into an experimental group of 241 cases and a control group of 236 cases using a random number table method.After surgery,they were all treated with a rotary hemostatic device for compression hemostasis.The experi-mental group implement improvement strategies for surgical limb management,specifically underwent a reverse Bar-beau test upon returning to the ward after surgery to achieve non-occlusive compression,followed by decompression every hour.The compression intensity of the control group was guided by palpating the distal radial artery pulsa-tion,and the first decompression was performed 1 hour after surgery,followed by decompression at intervals of every 2 hours.The main evaluation indicators are the incidence of surgical limb complications and simplified Chinese version of General Comfort Questionnaire(GCQ)scores in 2 groups of patients,while the secondary evaluation indi-cators are the duration of compression and the number of decompression times in both groups.Results The inci-dence of postoperative complications in the experimental group was 14.11%,which was statistically significant com-pared to 44.49%in the control group(χ2=53.308,P<0.001).The GCQ score of the experimental group was(77.71±5.43)points,which was higher than(74.66±5.83)points in the control group,and the difference was statistically signif-icant(t=-3.354,P=0.001).The compression duration of(172±52)minutes and decompression frequency of 2(2,3)in the experimental group were lower than(289±60)minutes and 4(3,4)in the control group,and the differences were statistically significant(P<0.001).Conclusion The non-occlusive compression method of the radial artery based on the reverse Barbeau test can significantly reduce limb complications in patients undergoing coronary inter-vention,shorten the duration of hemostatic compression,reduce the number of depressions,and improve patient com-fort.It provides objective basis for nursing staff to evaluate the intensity of hemostatic compression and the timing of decompression.

Objective:To investigate the clinical features of patients with chronic obstructive pulmonary disease (COPD) and serum-positive specific IgE (SIgE).Methods:This study was a retrospective cohort study. A total of 105 stable COPD patients with allergic features and completed serum SIgE testing were included, and all of them were from Capital Medical University, Beijing Tong Ren Hospital from September 2022 to October 2023. Those with at least one positive result of SIgE testing were classified as positive SIgE COPD group, and those with negative SIgE were classified as negative SIgE COPD group. There were 32 cases (30.5%) in the positive SIgE COPD group and 73 cases (69.5%) in the negative SIgE COPD group. Differences in laboratory tests, pulmonary function, chronic obstructive pulmonary symptom scores, incidence of severe acute exacerbation events in the past year, and drug therapy were compared between the two groups. The risk factors for positive SIgE COPD were analyzed, and the best predictive value for the diagnosis of positive SIgE COPD was analyzed using the area under the curve (AUC) of receiver operating characteristic (ROC).Results:Compared with the negative SIgE COPD group, the percentage of positive SIgE COPD group with rhinitis, sinusitis, sinusitis with nasal polyps, eczema, and a history of drug or food allergy were higher (all P<0.05) and the percentage of those who had quit smoking were higher ( P<0.05); the percentage of IgE above normal thresholds, the level of IgE, the percentage of peripheral blood eosinophil (EOS%), the count of EOS, and fractional exhaled nitric oxide (FeNO) were higher (all P<0.05), and the percentage of those who had severe and above severe Global Strategy for the Diagnosis, Management, and Prevention of COPD (GOLD) pulmonary function classification were higher, while the percentage of forced expiratory volume in one second (FEV 1% predicted), 25% maximal expiratory flow (MEF 25%) and MEF 75/25% were lower, and FEV 1/FVC was higher (all P<0.05). The positive SIgE COPD group had higher modified British medical research council (mMRC) scores and COPD assessment test (CAT) scores, and a higher incidence of severe acute exacerbation events over the past year (all P<0.05), and the use of short-acting β 2 receptor agonists (SABA) or short-acting muscarinic antagonist (SAMA), inhaled corticosteroid (ICS), theophylline and oral hormone therapy were more frequent (all P<0.05). EOS% ( OR=1.252, 95% CI: 1.039-1.508) was a risk factor for SIgE positivity in COPD ( P<0.05), and having quit smoking ( OR=0.385, 95% CI: 0.197-0.751) was a protective factor ( P<0.05). The AUC value of the ROC curve of EOS%>2.5% for the diagnosis of SIgE positivity was 0.647 (95% CI: 0.543-0.752), with a sensitivity and specificity of 52.8% and 73.1%, respectively. Conclusions:Positive SIgE COPD has sever clinical symptoms, high risk of acute exacerbation and deficiencies in treatment. The elevate of EOS% is a risk factor for the development of positive SIgE in COPD patients; positive SIgE COPD meets the diagnostic criteria for allergic COPD phenotype, and EOS% over 2.5% is suggestive of the clinical detection of allergic COPD phenotype.
