OBJECTIVE: To elucidate how spinal manipulative therapy (SMT) exerts its analgesic effects through regulating brain function in lumbar disc herniation (LDH) patients by utilizing resting-state functional magnetic resonance imaging (rs-fMRI). METHODS: From September 2021 to September 2023, we enrolled LDH patients (LDH group, n=31) and age- and sex-matched healthy controls (HCs, n=28). LDH group underwent rs-fMRI at 2 distinct time points (TPs): prior to the initiation of SMT (TP1) and subsequent to the completion of the SMT sessions (TP2). SMT was administered once every other day for 30 min per session, totally 14 treatment sessions over a span of 4 weeks. HCs did not receive SMT treatment and underwent only one fMRI scan. Additionally, participants in LDH group completed clinical questionnaires on pain using the Visual Analog Scale (VAS) and the Japanese Orthopedic Association (JOA) score, whereas HCs did not undergo clinical scale assessments. The effects on the brain were jointly characterized using the amplitude of low-frequency fluctuations (ALFF) and regional homogeneity (ReHo). Correlation analyses were conducted between specific brain regions and clinical scales. RESULTS: Following SMT treatment, pain symptoms in LDH patients were notably alleviated and accompanied by evident activation of effects in the brain. In comparison to TP1, TP2 exhibited the most significant increase in ALFF values for Temporal_Sup_R and the most notable decrease in ALFF values for Paracentral_Lobule_L (voxelwise P<0.005; clusters >30; FDR correction). Additionally, the most substantial enhancement in ReHo values was observed for the Cuneus_R, while the most prominent reduction was noted for the Olfactory_R (voxelwise P<0.005; clusters >30; FDR correction). Moreover, a comparative analysis revealed that, in contrast to HCs, LDH patients at TP1 exhibited the most significant increase in ALFF values for Temporal_Pole_Sup_L and the most notable decrease in ALFF values for Frontal_Mid_L (voxelwise P<0.005; clusters >30; FDR correction). Furthermore, the most significant enhancement in ReHo values was observed for Postcentral_L, while the most prominent reduction was identified for ParaHippocampal_L (voxelwise P<0.005; clusters >30; FDR correction). Notably, correlation analysis with clinical scales revealed a robust positive correlation between the Cuneus_R score and the rate of change in the VAS score (r=0.9333, P<0.0001). CONCLUSIONS Long-term chronic lower back pain in patients with LDH manifests significant activation of the "AUN-DMN-S1-SAN" neural circuitry. The visual network, represented by the Cuneus_R, is highly likely to be a key brain network in which the analgesic efficacy of SMT becomes effective in treating LDH patients.

Objective:To design an assisted management system for medical consumables that integrated management logic of diagnosis related groups(DRG)for disease,so as to standardize the use for medical consumables and to strengthen regulatory efficiency.Methods:The system was designed by a microservices architecture,and the data fusion of business data,data of diagnosis and treatment,and DRG data was realized through constructed data lake.A knowledge graph of associated rule for medical consumables was established,and the intelligent analysis function included prediction for demand,usage optimization,and anomaly detection was provided to assist management decision-making on the basis of inference for historical data and knowledge,and multi-dimensional data queries.A rule engine was deployed at key clinical nodes for real-time compliance review and intelligent alerts.A DRG-based business management process was constructed to cover full lifecycle of consumables,including admission,procurement,warehousing,storage,requisition,usage billing,and traceability,so as to realize real-time monitoring and early warning for consumable costs at the DRG level.Six clinical doctors with 2-3 years of experience in using medical consumable were selected as test users from Tangdu Hospital of the Air Force Medical University,and they were randomly assigned into a system group and a control group,with 3 subjects in each group.The system group utilized the auxiliary management system for medical consumable to perform prediction for the demand of monthly procurement,and rationality verification of consumable.The control group relied on individual experience of doctors.The predicted monthly procurement demand for medical consumables,the accuracy of verifying rationality of using medical consumables between two groups were compared,and the efficiencies of two kinds of management modes also were compared.Results:The accuracy rate of system group was 89.17%in predicting the monthly procurement demand for medical consumables,and the rate of checking accuracy and the rate of checking comprehensiveness of system group were respectively 87.50%and 91.67%in verifying rationality of using medical consumables,which were significantly higher than those of control group,and the differences were significant(x2=6.62,1.96,16.73,P<0.05).The durations of predicting the demand for procurement,and verifying and testing the rationality of consumables in system group were significantly shorter than these in control group[(3.54±0.45)s,(2.23±0.15)s],and the differences were statistically significant(t=1.97,1.65,P<0.05).Conclusion:The medical consumables auxiliary management system integrated with DRG management logic can significantly enhance the accuracy of monthly demand prediction for consumables and the recall rate and precision rate of rationality verification for consumables usage,while greatly improving work efficiency.It is conducive to enhancing the standardized and refined supervision level of consumables usage.

With the rapid development of competitive sports, the incidence of anterior cruciate ligament (ACL) injury is on the rise. Such injuries may shorten athletes′ career and lead to other long-term adverse consequences. Although athletes generally recover well after ACL reconstruction, many still struggle to return to their pre-injury performance levels. Advances in the understanding of ACL anatomy and injury mechanisms, along with the evolution of surgical techniques and rehabilitation methods, have provided more individualized and tailored options for athletes following ACL injuries. However, there is currently no consensus in China regarding surgical and rehabilitation strategies for competitive athletes aiming to return to sports after ACL injuries. To this end, the Sports Medicine Committee of the Chinese Research Hospital Association and the Editorial Board of the Chinese Journal of Trauma jointly formulated the Expert consensus on surgical treatment and rehabilitation for competitive sports athletes returning to sports after anterior cruciate ligament injury ( version 2025), and presented 14 recommendations covering surgical indications, preoperative rehabilitation, surgical timing, surgical strategies and postoperative rehabilitation strategies, aiming to improve the surgical treatment and rehabilitation system for ACL injuries in competitive athletes and facilitate their return to high-level sports performance after injury.

Sacroiliac complex injuries are commonly seen in high-energy pelvic fractures. The injuries make a big difference in treatment patterns due to the diverse injury types, posing considerable challenges in formulating optimal treatment strategies, and hence are persistent clinical difficulties in orthopedic trauma. The clinical management of sacroiliac complex injuries presents several key challenges such as a non-negligible rate of missed diagnoses in associated vascular and visceral injuries, absence of standardized protocols for surgical approaches and reduction-fixation strategies across different injury patterns, and ongoing controversies regarding surgical indications and optimal timing for patients combined with concomitant lumbosacral plexus injuries. Currently, no systematic clinical guidelines are available for the diagnosis and treatment of sacroiliac complex injuries both domestically and internationally. To this end, the Pelvic and Acetabular Surgery Group, Orthopedic Branch, China International Exchange and Promotive Association for Medical and Health Care and Orthopedic Physician Branch, Chinese Medical Doctor Association organized a panel of domestic experts in the field to develop the Clinical guideline for the diagnosis and treatment of sacroiliac complex injuries ( version 2025), based on evidence-based medicine and adhering to the principles of scientific rigor, clinical applicability, and innovation. These guidelines provided 11 recommendations covering diagnosis, therapeutic principles and techniques, management protocols for lumbosacral plexus injuries, outcome evaluation, and postoperative rehabilitation pathways, etc., aiming to standardize the clinical management of sacroiliac complex injuries.

Objective:To investigate the relationship between daily physical exercise and frailty state among elderly inpatients in internal medicine department.Methods:A cross-sectional study was conducted among eligible elderly patients who hospitalized at the internal medicine department of Beijing Hospital from September 2018 to March 2019.Frailty was screened using the FRAIL scale, and their pre-hospitalization daily physical exercise was assessed through a questionnaire upon admission.The statistical methods include correlation analysis and logistic regression univariate and multivariate analysis.Results:A total of 533 eligible elderly patients in internal medicine were included in the study, with 129(24.2%)frail, 296(55.5%)pre-frail, and 108(20.3%)non-frail patients.328 patients(61.5%)exercised more than 5 times a week, while 102 patients(19.1%)hardly exercised at all.Physical exercise frequency had negative correlation with the FRAIL frailty score( r=-0.576, P<0.001).Both univariate and multivariate logistic regression analysis shown daily physical exercise frequency was significantly associated with frailty( OR=0.56, 95% CI: 0.49-0.65, P<0.001)among elderly inpatients in internal medicine. Conclusions:For elderly inpatients in internal medicine department, daily physical exercise frequency is closely related to frailty status, serving as an independent factor in reducing the occurrence of frailty.Therefore, increasing the frequency of daily physical exercises is an effective measure to reduce the risk of frailty for this group of patients.

Objective:To compare surgical-related indicators between non-inflated subclavian endoscopic surgery and axillary and traditional open surgery for the treatment of right lobe thyroid cancer,as well as their effects on postoperative anterior cervical function and cosmetic outcomes.Methods:This retrospective cohort study analyzed 151 cases of thyroid cancer patients who underwent surgical treatment at the Department of Thyroid Surgery,Zhengzhou Central Hospital Affiliated to Zhengzhou University from June 2024 to October 2024. Based on the surgical approach,patients were divided into three groups:56 cases of traditional open surgery group, 44 cases of non-inflated axillary approach group,and 51 cases of non-inflated subclavian approach group. Comparative indicators included surgical time, parathyroid autotransplantation rate,complete exposure rate of central area, number of lymph node dissections, number of positive lymph nodes, anterior cervical function, and satisfaction with incision beauty. One-way analysis of variance,non-parametric test,Kruskal-Wallis test,Pearson χ2 test and Fisher′s exact probability method were used to compare the results of the three groups and subsequent pairwise comparisons,respectively. Results:All laparoscopic surgeries were successfully completed without conversion to open surgery. (1) Surgical time:the traditional open surgery group had the shortest operative time ( M(IQR))(71.5(16.0)minutes), significantly shorter than both endoscopic groups (both P<0.01); among the endoscopic approaches, the non-inflated subclavian approach group (97.0(10.0)minutes) had a significantly shorter operative time than the non-inflated axillary approach group (115.0(11.0)minutes)( P<0.01). (2) Parathyroid autotransplantation rate:the rates were 53.6%(30/56) in the traditional group, 70.5%(31/44) in the non-inflated axillary approach group, and 66.7%(34/51) in the non-inflated subclavian approach group, with no statistically significant differences ( P>0.05). (3) Complete exposure rate of the central area:the exposure rate was 100%(56/56) in the traditional open surgery group, 86.4%(38/44) in the non-inflated axillary approach group, and 96.1%(49/51) in the non-inflated subclavian approach group. A significant difference was observed between the traditional open surgery group and the non-inflated axillary approach group ( χ2=8.124, P<0.01), but not observed between other groups. (4) Number of lymph node dissection:no significant difference was found among the three groups (8(6)(range:2 to 17) in the traditional open surgery group,7(3)(range:2 to 16) in the non-inflated axillary approach group,7(4)(range:2 to 16) in the non-inflated subclavian approach group)( P=0.078).(5) Number of positive lymph nodes:no significant differences were observed among the three groups( P=0.923). (6) Postoperative anterior cervical function:① Visual analogue scale: there was no significant difference between the non-insufflation transaxillary approach group and the non-insufflation subclavian approach group at 3 days and 1 month postoperatively ( P>0.017). However, the two groups had significantly lower scores than the traditional open group (both P<0.01). ② Neck disability index:at 3 days post-surgery, there were significantly lower in the axillary and subclavian groups compared to the traditional open group ( P<0.01), with no significant difference between the two endoscopic groups( P>0.017); at 1 month postoperatively, the traditional open surgery group, gasless axillary approach group, and gasless subclavian approach group, with statistically significant differences between each group (both P<0.01). ③ Swallowing disorder index: no significant differences were observed at 3 days post-surgery( P>0.05); however, at 1 month post-surgery, the endoscopic groups showed significantly lower scores compared to the traditional open group(both P<0.01).(7) Satisfaction with incision beauty:significant differences were found among the three groups in terms of vancouver scar scores, patient scar assessment scores, and observer scar assessment scores(all P<0.01). Conclusions:Compared to the non-inflated axillary endoscopic thyroidectomy, the non-inflated subclavian approach offers a technically simpler procedure, better exposure of the central lymph node dissection area, and superior protection of anterior cervical function, although it results in less favorable cosmetic outcomes. Under strict preoperative evaluation and appropriate indications,both non-inflated subclavian and axillary approaches can achieve outcomes comparable to traditional open surgery for cN0 thyroid cancer,demonstrating good clinical application value.

Objective To investigate the metabolic characteristics of patients with early-onset type 2 diabetes mellitus(T2DM)and to develop a risk prediction model for microvascular complications.Methods A retrospective study was conducted on 980 T2DM patients admitted for treatment between April 2020 and April 2024.Based on age at diagnosis,the patients were divided into two groups,an early-onset T2DM group(age at diagnosis<40 years,n=265)and a late-onset T2DM group(age at diagnosis≥40 years,n=715).Differences in metabolic indicators between the two groups were compared.Patients in the early-onset group were further divided into a complication subgroup(n=142)and a non-complication subgroup(n=123)based on the presence or absence of microvascular complications.Data on baseline characteristics,metabolic parameters,and laboratory indicators were collected and compared between the two groups.Multivariate logistic regression analysis was used to identify independent risk factors for microvascular complications,and a nomogram prediction model was constructed.The model's discriminative performance was assessed using receiver operating characteristic(ROC)curves,and its calibration was evaluated using calibration curves and the Hosmer-Lemeshow test.Decision curve analysis(DCA)was also performed to assess the model's clinical utility.Results Compared with the late-onset group,patients in the early-onset group exhibited more pronounced metabolic abnormalities,including higher body mass index(BMI),proportion of family history of diabetes mellitus,glycated hemoglobin(HbA1c)levels,total cholesterol(TC),triglycerides(TG),low-density lipoprotein cholesterol(LDL-C),triglyceride-glucose index(TyG),and lactate dehydrogenase(LDH)levels(all P<0.05),along with a shorter disease duration and lower levels of high-density lipoprotein cholesterol(HDL-C)(P<0.05).According to a multivariate analysis,systolic blood pressure(SBP),total bilirubin(TBIL),HDL-C,LDL-C,TyG,and LDH were identified as independent risk factors for microvascular complications in patients with early-onset T2DM.A predictive model based on these factors was established as the follows,Log(P)=-19.915+0.017×SBP-0.136×TBIL-1.241×HDL-C+0.684×LDL-C+0.769×TyG+0.050×LDH.The area under the ROC curve(AUC)was 0.864(95%CI,0.820-0.907),and the Hosmer-Lemeshow test indicated good model fit(χ2=10.286,P=0.246).The slope of the DCA curve was also close to 1.Conclusion The nomogram prediction model based on SBP,TBIL,HDL-C,LDL-C,TyG,and LDH demonstrates good predictive performance for microvascular complications and can provide a reference for clinical risk stratification and individualized intervention.

Objective To comparatively analyze the clinical characteristics of primary bilateral macronodular adrenal hyperplasia(PBMAH)and adrenal cortisol-producing Adenoma(CPA),and enhance the understanding of two diseases.Methods The clinical data of 85 PBMAH patients(PBMAH group)and 195 CPA patients(CPA group)diagnosed at Department of Endocrinology,the First Medical Center of Chinese PLA General Hospital,from September 2014 to August 2024 were retrospectively analyzed.The demographic characteristics,comorbidities,biochemical indicators,adrenocorticotropic hormone-cortisol(ACTH-F)levels,and adrenal imaging features and treatment conditions were compared between the two groups.Results(1)General characteristics:Compared with CPA group,PBMAH group had older age at diagnosis and a higher proportion of male patients.(2)Clinical characteristics:Compared with CPA group,PBMAH group had a longer disease duration,a higher proportion of subclinical Cushing's syndrome(CS),and a higher proportion of hypertension,impaired glucose tolerance/diabetes,bone mass reduction or osteoporosis,with higher serum potassium levels,and the differences were statistically significant(P<0.01).(3)Hormone levels:Both PBMAH and CPA groups showed ACTH-F rhythm disorder,significantly increased cortisol levels and suppressed ACTH.Compared with PBMAH group,CPA group had stronger autonomous cortisol secretion ability,manifested by increased midnight serum cortisol(F0:00),16:00 serum cortisol(F16:00),24-hour urinary free cortisol(24 h UFC)levels and lower 8:00 serum ACTH(ACTH8:00)and 16:00 serum ACTH(ACTH16:00)(P<0.01).After low-dose dexamethasone suppression test(LDDST),CPA group showed lower suppression rates of ACTH and cortisol,and higher proportions of paradoxical elevation in serum cortisol and 24 h UFC compared with PBMAH(P<0.01).Conclusions PBMAH has a longer disease course and higher proportions of comorbid metabolic disorders than CPA,mostly manifested as subclinical Cushing's syndrome.CPA has stronger autonomous cortisol secretion ability,with cortisol less likely to be suppressed after LDDST and more obvious paradoxical elevation of cortisol and 24 h UFC.

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.

Aim To study the effects of whole herb of Prunella and its active components on the malignant progression of breast cancer and its mechanism.Meth-ods Breast cancer transplantation tumor model was constructed and randomly divided into the model group,low,medium and high dose group of whole herb of Prunella(0.1,0.2,0.4 g·mL-1 by gavage)and paclitaxel(10 mg·kg-1 by intraperitoneal injection),which was administered by gavage every day,and the tumor tissues were collected after 28 days of interven-tion.The weight,tumor volume and mass of nude mice in each group were detected,HE staining was used to observe the morphology of breast cancer tumor tissues,and immunohistochemical staining was used to observe the proliferation of cell-cycle regulatory protein-67(Ki-67)and cytokeratin 17(CK17)in breast cancer tumor tissues.The cellular experiments were performed by u-sing different concentrations of the ethyl acetate extract of the whole herb of Prunella in breast cancer MDA-MB-231 cells for 24 h.The proliferation of MDA-MB-231 cells and the effects on the cell cycle and apoptosis of MDA-MB-231 cells were detected by using the CCK-8 assay,the cell cycle flow and the apoptotic cell flow.Western blot was used to detect the effect of ethyl ace-tate extract of whole herb of Prunella on the expression of apoptosis-related proteins in breast cancer MDA-MB-231 cells.UPLCQ-TOF MS/MS was used to detect the chemical compositions of the ethyl acetate extract of Prunella whole herb.Results The whole herb of Pru-nella had no significant effect on the growth of nude mice(P＞0.05);it could significantly inhibit the growth of transplanted tumors in nude mice with human breast cancer(P＜0.05);the results of HE staining showed that the cells in the tissues appeared to be rela-tively sparse with the increase of the dose of Prunella and had different degrees of nuclear consolidation and deep staining of nuclei and the apoptosis of the tumor cells increased;the metastasis of tumor cells to the liv-er and lungs was inhibited,when compared with that in the model group.Compared with the model group,the low,medium and high groups of Prunella had no signif-icant effect on the liver index,while the spleen index was significantly reduced(P＜0.05);the expression of Ki-67 and CK17 was reduced.The ethyl acetate ex-tract of the whole herb of Prunella could inhibit the proliferation of MDA-MB-231 cells in breast cancer(P＜0.01);the results of flow cytometry showed that,with the increase of the concentration of the ethyl ace-tate extract of the whole herb of Prunella,the proportion of S-phase cells in the MDA-MB-231 cells significantly increased,and the proportion of G0/G1-phase cells sig-nificantly decreased,while the proportion of G2-phase cells did not change significantly(P＜0.01);Western blotting was not affected in the low,medium and high groups,and the spleen index significantly decreased(P＜0.05);the expression of Ki-67 and CK17 was re-duced;the results of Western blot showed that the eth-yl acetate extract of the whole herb of Prunella promo-ted the expression of Bax,cleaved caspase-3,cleaved caspase-9 proteins,and inhibited the expression of Bcl-2,caspase-3,caspase-9,cyclinA2,and CDK2 proteins(P＜0.05,P＜0.01).The acetic acid of the whole herb of Prunella ethyl ester extract identified a total of 51 compounds.Conclusions The whole herb of Pru-nella can inhibit the growth of breast cancer in nude mice transplanted with tumors,promote the apoptosis of tumor cells,inhibit the proliferation of breast cancer MDA-MB-231 cells,inhibit the metastasis of tumor cells to the liver and lungs,protect the liver and spleen,and reduce the expression of the value-added markers Ki-67 and CK17 in tumor tissues,and the ef-fective ingredient of the whole herb,the ethyl acetate extract,can induce apoptosis.The mechanism may be related to the down-regulation of cyclinsA2,CDK2,Bcl-2,caspase-3,caspase-9 and up-regulation of Bax,cleaved caspase-3,cleaved caspase-9 protein expres-sion.
