OBJECTIVE To provide a reference for the quality control of Hypericum perforatum. METHODS High- performance liquid chromatography （HPLC） was used to establish fingerprints for 20 batches of H. perforatum and determine the contents of its main components： chlorogenic acid， rutin， hyperin， isoquercitrin， avicularin， quercitrin and quercetin. Cluster analysis was conducted using SPSS 26.0 software. The chromaticity values （luminance value L*， red-green value a*， and yellow- blue value b*） of H. perforatum powder were measured using electronic eye. A prediction model for the contents of seven components in H. perforatum based on its appearance chromaticity values was established using machine learning algorithms. The predictive performance of the models was evaluated using root-mean-square-error （RMSE）. RESULTS A total of 16 common peaks were calibrated in the fingerprints of 20 batches of H. perforatum， and 9 peaks were identified， which were chlorogenic acid， rutin， hyperin， isoquercitrin， avicularin， quercitrin， quercetin， hypericin and hyperforin； the similarities of the 20 batches of samples and reference fingerprint ranged from 0.889-0.987. The contents of chlorogenic acid， rutin， hyperin， isoquercitrin， avicularin， quercitrin and quercetin were 0.025%-0.166%， 0.048%-0.339%， 0.082%-0.419%， 0.017%-0.209%， 0.011%-0.134%， 0.020%-0.135%， 0.041%-0.235%， respectively. Cluster analysis results showed that 18 batches of qualified H. perforatum were grouped into three categories， when the Euclidean distance was set to 1.4. L* of the 20 batches of H. perforatum ranged from 62.814 to 75.668， a* ranged from 1.409 to 3.490， and b* ranged from 25.249 to 30.759. RMSE of three prediction models， namely XGBoost， LightGBM， and AdaBoost， ranged from 0.008 to 0.070， indicating good fitting performance. XGBoost model predicted the contents of the other six components with high accuracy， except for rutin. CONCLUSIONS The established fingerprints and content determination methods are accurate， reproducible， and reliable. The content prediction model based on appearance chromaticity values， combined with machine learning algorithms， can be used for the quality control of H. perforatum.

BACKGROUND:The definitive cause of adolescent idiopathic scoliosis is not yet known.The search for a clinical approach to address adolescent idiopathic scoliosis is imminent.OBJECTIVE:To investigate the effect of Schroth therapy combined with core strength training on mild adolescent idiopathic scoliosis and to provide more bases for the clinical treatment of mild adolescent idiopathic scoliosis.METHODS:110 patients with mild adolescent idiopathic scoliosis attending the Department of Rehabilitation Medicine and Department of Spine Surgery of Affiliated Hospital of Nantong University from July 2022 to January 2024 were selected as the study subjects.They were divided into the trial group and the control group according to the wishes of the patients and their parents,with 55 cases in each group.The control group was observed and followed up,and the trial group underwent Schroth therapy combined with core strength training for 45 minutes a day for 24 weeks.The differences in imaging parameters,body surface indexes,three-dimensional ultrasound imaging angle,and quality of life were compared between the two groups before and after treatment.RESULTS AND CONCLUSION:(1)At 24 weeks after treatment,major curve Cobb,apical vertebral translation,and cervical lordosis were significantly improved in the trial group(P＜0.05),while there was no significant difference in the control group(P＞0.05).Major curve Cobb and apical vertebral translation in the trial group were significantly better than those in the control group(P＜0.05).(2)At 24 weeks after treatment,angle of trunk rotation in the trial group was significantly lower than that before treatment(P＜0.05),while there was no significant difference between before and after treatment in the control group(P＞0.05),and angle of trunk rotation in the trial group was significantly lower than that of the control group(P＜0.05).(3)At 24 weeks after treatment,the center of laminae angle of three-dimensional ultrasound imaging was significantly reduced in the trial group(P＜0.05),while there was no significant difference in the control group before and after treatment(P＞0.05).The center of laminae angle of three-dimensional ultrasound imaging was smaller in the trial group than that in the control group(P＜0.05).(4)At 24 weeks after treatment,in terms of the quality of life,pain dimension score in the trial group was significantly increased(P＜0.05).Both trial and control groups showed significantly higher scores in the self-image dimension compared with that before treatment(P＜0.05).Both groups had significantly lower scores in the mental health dimension compared with that before treatment(P＜0.05).In the dimensions of pain,self-image,mental health,and satisfaction,the trial group was significantly higher than the control group(P＜0.05).(5)It is indicated that Schroth therapy combined with core strength training can improve the major curve Cobb,apical vertebral translation,and cervical lordosis angle,reduce the angle of trunk rotation,decrease the center of laminae angle of three-dimensional ultrasound imaging,and improve the quality of life,and it is effective in the treatment of mild adolescent idiopathic scoliosis.

ObjectiveTo investigate the effect and underlying mechanism of the Wulao Qisun prescription on pathological new bone formation in ankylosing spondylitis （AS）. MethodsSynovial fibroblasts were isolated from the hip joints of AS patients and observed under a microscope to assess cell morphology. The cells were identified using immunofluorescence staining. The isolated AS fibroblasts were divided into blank group， low drug-containing serum group， medium drug-containing serum group， high drug-containing serum group， and positive drug group. After drug intervention， cell proliferation was measured using the cell counting kit-8 （CCK-8） assay to observe fibroblast growth and determine the optimal intervention time. Alkaline phosphatase （ALP） activity was measured using the alkaline phosphatase assay. Protein expression of osteocalcin （OCN）， osteopontin （OPN）， and runt-related transcription factor 2 （Runx2） was detected by Western blot. The mRNA expression levels of Wnt5a， β-catenin， and Dickkopf-1 （DKK-1） were measured by real-time quantitative polymerase chain reaction （Real-time PCR）. ResultsCompared with the blank group， each drug-containing serum group of Wulao Qisun prescription and the positive drug group inhibited the proliferation of AS fibroblasts and reduced ALP expression （P<0.01）. Compared with the blank group， the low drug-containing serum group of Wulao Qisun prescription downregulated β-catenin mRNA expression （P<0.05）. The medium and high drug-containing serum groups and the positive drug group significantly downregulated Wnt5a and β-catenin mRNA expression （P<0.05， P<0.01）， with the positive drug group showing the most pronounced effect （P<0.01）. The high drug-containing serum group and the positive drug group significantly upregulated DKK-1 mRNA expression （P<0.01）. Compared with the blank group， the low drug-containing serum group of Wulao Qisun prescription inhibited the expression of OPN and Runx2 proteins （P<0.05， P<0.01）， while the medium and high drug-containing serum groups and the positive drug group inhibited the expression of OCN， OPN， and Runx2 proteins （P<0.05， P<0.01）. ConclusionThe Wulao Qisun prescription can inhibit the proliferation and osteogenic differentiation of AS fibroblasts， thereby delaying the formation of pathological new bone in AS. The possible mechanism involves the regulation of Wnt/β-catenin-related gene expression， further inhibiting the transcription of downstream target genes.

Objective:To establish a scoring system for preoperative prediction of the malignant potential of gastric stromal tumors based on gastroscopic and endoscopic ultrasound features, along with validation.Methods:A total of 286 patients who were treated in Jiangsu Province Hospital of Chinese Medicine from January 1, 2017 to December 31, 2023 and diagnosed as having gastric stromal tumors by postoperative pathology were enrolled in the modeling group. According to National Institutes of Health classification system, 227 very-low/low-risk patients were classified into the low malignant potential (LMP) group, and the 59 intermediate/high-risk patients into the high malignant potential (HMP) group. LASSO regression analysis was performed to identify predictive factors for HMP gastric stromal tumors, and a nomogram prediction model was developed. Internal validation using the Bootstrap method was performed on the modeling group, and external validation was performed on data from 85 patients who were treated and diagnosed as having gastric stromal tumors by postoperative pathology in Taizhou People's Hospital from January 1, 2021 to December 31, 2023. The receiver operator characteristic (ROC) curves, calibration curves, and decision curve analyses were employed in both the modeling and external validation groups.Results:Tumor size (coef=0.755), tumor shape (coef=0.015), tumor location (coef=0.008), growth pattern (coef=-0.026), cystic change (coef=0.685), and surface unceration change (coef=-0.545) were the independent predictive factors for HMP gastric stromal tumors. The nomogram-based prediction model constructed using these factors achieved an area under the ROC curve of 0.959 (95% CI: 0.898-0.903) in the modeling group and 0.959 (95% CI: 0.857-1.000) in the external validation group. The model demonstrated good accuracy (0.917) and a Kappa value of 0.737 in internal validation. Calibration curve and decision curve analyses indicated strong calibration and high net benefit in both the modeling and the external validation groups. Conclusion:Tumor size, tumor shape, tumor location, growth pattern, cystic change, and surface ulceration change are independent predictive factors for HMP gastric stromal tumors. The nomogram model developed based on these factors offers effective and convenient visualization for clinicians to predict the malignant potential of gastric stromal tumors preoperatively.

Rheumatoid arthritis(RA)is an autoimmune disease with the basic pathological manifestation of synovial inflammation.Symmetric poly-articular pain and swelling are the main symptoms in clinical practice,and even extra-articular manifestations and comorbidities such as interstitial fibrosis and coronary artery disease are triggered,which seriously affect the quality of life of patients.Traditional Chinese medicine(TCM)has achieved good clinical efficacy in the prevention and treatment of RA with the advantages of multi-pathway,multi-target,multi-component,and less toxic side effects,and plays an important role in the treatment of RA.Recently,many studies have demonstrated that Chinese medicine monomers and Chinese herbal compound can control inflammation,reduce angiogenesis,induce apoptosis of synovial fibroblasts,and inhibit their proliferation,invasion and migration by regulating the PI3K/Akt signaling pathway,so as to play a key role in the treatment of RA.For this reason,the article summarizes current knowledge regarding the PI3K/Akt signaling pathway and its role in RA,as well as summarizes the current research progress of TCM in the treatment of RA by regulating the PI3K/Akt signaling pathway.The aim of this review is to provide theoretical bases for the prevention and treatment of RA and the development of new drugs.

Ankylosing spondylitis(AS)is a chronic inflammatory autoimmune disease characterized by inflammatory back pain.Its pathological features mainly include inflammation,bone destruction,and pathologic new bone formation.The etiology of AS is complex,and it may be related to genetics,infections,the environment,and intestinal flora.Its pathogenesis has not yet been clarified.In recent years,osteoimmunology,as a new theme in the study of inflammatory arthritis,plays an important role in the pathogenesis and development of AS,which was embodied in the inflammatory response and imbalance of bone metabolism.Traditional Chinese medicine(TCM)has the characteristics of multiple pathways,multiple components,multiple targets and multiple levels.TCM can improve the inflammatory response and bone metabolism imbalance of AS by regulating the osteoblasts of the skeletal system and the related factors of the immune system,thus to prevent and control AS.For this reason,the paper summarizes the role of bone immunology in the pathogenesis of AS,and reviews the current status of research on the intervention of TCM in bone immunology for the treatment of AS,with a view to providing certain references for the future clinical application of TCM in the prevention and treatment of AS.

AIM:To investigate the inhibitory ef-fect of Zushima ointment on inflammation and bone destruction in CIA mice.METHODS:SPF grade male DBA/1 mice were used,6 were random-ly selected as the normal group,and 18 CIA mice that were successfully modelled were randomly di-vided into the model group,the plaster group(1.0 g/kg),and the fuselage group(0.12 g per time)ac-cording to the random number table method,6 mice in each group,and each administered group was given medication according to the body mass,and saline was given to both the normal and model groups.The normal group and the model group were given saline,and breathable adhesive paper was applied once a day for 4 h/session for 4 consec-utive weeks.The arthritis scoring index was used to observe the changes of arthritis symptoms and ar-thritis index scores of mice in each group.Micro-CT was used to observe the damage of hind paw of mice,real-time fluorescence PCR was used to de-tect the mRNA expression of IL-17,IL-1β and TNF-αin ankle joint tissues,and immunohistochemistry was used to detect the expression of OPG and RANKL proteins in ankle joint tissues,and hematox-ylin-eosin(HE)staining was used to observe the pathological changes of synovial tissues after the treatment.The pathological changes of synovial tis-sue were observed after hematoxylin-eosin(HE)staining,and the changes of osteoclasts in ankle joint tissue were observed by anti-tartaric acid phosphatase(TRAP)method.RESULTS:Compared with the normal group,the arthritis index score of the model mice was significantly higher(P＜0.05).Micro-CT showed severe bone erosion in the hind paws of the mice,destruction of the bone surface and reduction of bone volume.The expression of IL-17,IL-1β and TNF-α mRNA(PCR)in the ankle joint tissues was significantly higher(P＜0.05).Im-munohistochemistry showed that the relative ex-pression of OPG protein in the ankle joint tissues was reduced(P＜0.05).Immunohistochemistry showed a decrease in the relative expression of OPG protein(P＜0.01)and an increase in the rela-tive expression of RANKL protein(P＜0.01).HE re-sults showed moderate inflammatory cell infiltra-tion,swelling of synovial cells,massive formation of vascular opacities and synovial hyperplasia;an increase in the number of osteoclasts,roughness of the surface of articular cartilage tissue,severe bone destruction and thinning of the cartilage lay-er.Compared with the model group,the arthritic symptoms of mice in the cream group and the futa-lin group were relieved and the arthritis index score was reduced;the bone density of the mice's hind paws improved,effectively relieving osteopo-rosis;the expression of IL-17,IL-1β and TNF-αmRNA(PCR)in the ankle joint tissue was signifi-cantly reduced(P＜0.05);the immunohistochemical results showed that the relative expression of OPG protein was increased(P＜0.05),the relative expres-sion of RANKL protein decreased(P＜0.01).HE re-sults showed that synovial cell enlargement was significantly improved,mild inflammatory cell infil-tration,synovial hyperplasia was not obvious;the number of broken bone was reduced,articular car-tilage destruction was significantly improved and relieved,and the thickness of cartilage layer was significantly increased.CONCLUSION:Ancestral hemp poultice relieves local symptoms of RA,re-duces the expression of inflammatory factors and attenuates the inflammatory response,possibly by inhibiting osteoclast differentiation and activation through modulation of the OPG/RANKL signalling axis,which further ameliorates the biological ef-fects of articular bone and cartilage destruction.

National health standards involve all kinds of technical requirements formulated and numbered in accordance with the procedures and formats stipulated in the standardisation system for the implementation of national health and hygiene laws, regulations and policies, and the protection of human health. The establishment of health standards in China should align with our legal framework, including laws, regulations, departmental rules, and health and hygiene policies. During the development of these standards, a comprehensive approach is advocated, encompassing in-depth investigations, rigorous demonstrations, and extensive stakeholder engagement. However, the process of standard formulation may suffer from insufficient research evidence. The evidence-based concept emphasizes the significance of evidence. Therefore, integrating evidence-based concept into the process of developing health standards can enhance the quality and scientific basis of these standards. This article systematically elucidates the current status and development process of health standards in China, explores the necessity and feasibility of incorporating evidence-based concept into the development of these standards, analyzes the challenges and opportunities, and presents reflections and suggestions.

ObjectiveTo explore the effectiveness and safety of Yiqi Huoxue Formula （益气活血方， YHF） in the adjuvant treatment of chronic pulmonary heart disease （CPHD） and heart failure （HF）with qi deficiency and blood stasis pattern. MethodsOne hundred and twenty patients with CPHD and HF with qi deficiency and blood stasis pattern were allocated randomly into treatment group and control group， with 60 case in each group. The control group was given conventional basic western medicine， while the treatment group was given oral administration of YHF granules in addition， one dose per day. The treatment course for both groups was 8 weeks. The TCM symptom scores， Minnesota Life Quality Scale （MLHF-Q） scores， echocardiographic indicators including right ventricular end-diastolic diameter （RVEDD）， left ventricular end-diastolic diameter （LVEDD）， left atrial end-diastolic diameter （LAEDD） and pulmonary artery mean pressure （PAMP）， six-minute walking distance （6MWD）， and plasma N-terminal pro-B-type natriuretic peptide （NT-ProBNP） level were compared between the groups. The effectiveness regarding cardiac function and TCM syndromes were compared between the two groups after treatment， and the occurrence of adverse events was observed. ResultsWith two drop-outs both in the treatment group and control group， and 58 cases in each group were included in the outcome analysis. The total effective rate regarding cardiac function and TCM syndromes in the treatment group were 91.38% （53/58） and 96.55% （56/58）， respectively， significantly higher than the corresponding 70.69% （41/58） and 48.27% （28/58） in the control group （P＜0.05）. After treatment， the TCM symptom scores and RVEDD level were significantly reduced in the treatment group， and MLHF-Q score， plasma NT-ProBNP level and PAMP level decreased significantly， while 6MWD increased in both groups （P＜0.01）. Compared to those in the control group， the TCM symptom scores， MLHF-Q score， plasma NT-ProBNP level and PAMP level significantly decreased， while 6MWD increased in the treatment group （P＜0.01）. There were no obvious abnormalities in the blood， urine， stool routine and liver and kidney function indicators in both groups. One adverse reaction each occurred in both groups， and there was no statistically significant difference in the incidence rates（P＞0.05）. ConclusionYHF combined with conventional western medicine can significantly improve the clinical efficacy， improve the clinical symptoms and cardiac function， increase the quality of life and exercise tolerance， and is relatively safe.
