BackgroundLow medication compliance among patients with severe mental disorders increases the disease burden on both the patients' families and the society. Medication adherence is influenced by numerous factors. Traditional methods such as Logistic regression struggle to quantify the importance of these factors. By introducing Extreme Gradient Boosting （XGBoost） combined with Shapley Additive Explanations （SHAP）， enables the quantification of the relative contribution weights of each factor， providing support for identifying the core influencing factors. ObjectiveTo explore the influencing factors of medication adherence among patients with severe mental disorders in Zhuhai， aiming to provide references for optimizing patient management strategies. MethodsExtract the data of patients with severe mental disorders who were registered on the mental health system platform in Zhuhai City from January 1， 2023 to March 31， 2025. A total of 9 329 patients were finally included for analysis. Influencing factors were screened using univariate analysis and multivariate logistic regression analysis， and an XGBoost model combined with the SHAP algorithm was constructed to quantify the importance of each influencing factor. ResultsAmong 9 329 patients， 8 446 demonstrated medication adherence， yielding an adherence rate of 90.53%. Multivariable analysis identified several risk factors significantly associated with medication non-adherence， being unmarried （OR=1.237， 95% CI： 1.019–1.502） or divorced （OR=1.389， 95% CI： 1.038–1.832）， a diagnosis of mental retardation with psychiatric disorders （OR=3.025， 95% CI： 2.402–3.796） or paranoid psychosis （OR=5.117， 95% CI： 3.086–8.299）， a disease duration of 2–4 years （OR=1.355， 95% CI： 1.085–1.696）， 4–6 years （OR=2.143， 95% CI： 1.671–2.747）， or >6 years （OR=1.681， 95% CI： 1.365–2.079）， lack of guardian subsidies （OR=1.412， 95% CI： 1.099–1.801）， absence of a disability certificate （OR=1.900， 95% CI： 1.588–2.282）， not being enrolled in care and support groups （OR=1.384， 95% CI： 1.183–1.617） or community services （OR=1.313， 95% CI： 1.042–1.645）， and not cohabiting with a guardian （OR=1.257， 95% CI： 1.048–1.501）. Conversely， the enrollment in special outpatient disease programs （OR=0.716， 95% CI： 0.609–0.842） and a family history of mental illness （OR=0.713， 95% CI： 0.503–0.982） were identified as protective factors. The XGBoost model exhibited robust predictive performance， with a sensitivity of 0.433， specificity of 0.944， accuracy of 0.891， Area Under the Curve （AUC） of 0.837， and F1 value of 0.449. Feature importance ranking indicated that the top three factors were disease duration， diagnosis， and the acquisition of disability certificates. ConclusionPolicy-based support （acquisition of disability certificates， special outpatient disease enrollment） and clinical disease characteristics （disease duration， diagnosis type） are key factors affecting medication adherence among patients with severe mental disorders in Zhuhai City. ［Funded by Zhuhai Medical Research Project （number， 2220009000281）］

Objective:To construct patient-derived xenograft (PDX) models from head and neck squamous cell carcinoma (HNSCC) patients, to explore the effect of immune reconstitution timing on the PDX modeling and immune microenvironment in humanized immune system mice (huHSC-NCG-hIL15), and to provide a reliable animal model for research on the mechanisms of head and neck squamous carcinoma and for studies on immune therapy drug interventions.Methods:This study enrolled 28 HNSCC patients (25 laryngeal carcinomas, 3 hypopharyngeal carcinomas). PDX models were established in Balb/c nude (nu) mice, NSG mice, and humanized immune system-reconstituted huHSC-NCG-hIL15 mice. Fresh HNSCC samples were transplanted into Balb/c nu and NSG mice to generate PDX models, with subsequent analysis of success-associated factors. One successfully established PDX tumor was subsequently implanted into humanized immune system-reconstituted huHSC-NCG-hIL15 mice. Tumor transplantation was performed at distinct immune reconstruction timepoints (2 vs. 7 weeks post-reconstitution), and tumor growth patterns were monitored. Flow cytometry and multiplex immunohistochemical staining were utilized to characterize immunological profiles in peripheral lymphoid organs and tumor microenvironments. Hematoxylin-eosin (HE) staining was employed to assess histomorphological concordance between primary patient tumors and PDX model tissues. Results:HNSCC PDX models were successfully established. NSG mice exhibited a higher and more stable tumor take rate compared to Balb/c nu mice (pilot study: 4/10 vs. 3/10 cases; mean take rate 60%-80% vs. 20%-60 %). The PDX success rate in NSG mice was 46.4% (13/28). In the huHSC-NCG-hIL15 mice model with immune reconstitution at 7 weeks, tumors grew significantly faster, and the PDX modeling process was shorter (617 mm3 at day 70 in 7-week cohort vs.280 mm3 in 2-week cohort). Flow cytometry analysis of the immune microenvironment showed that at 7 weeks of immune reconstitution, the proportions of B cells in the spleen and tumor tissues(2-week vs. 7-week: spleen 16.2% vs. 61.7%, tumor 26.0% vs. 38.8%) and myeloid cells in the spleen (2-week vs. 7-week: spleen 47.2% vs. 88.1 %) were significantly higher, while mice at 2 weeks post-reconstitution showed a higher proportion of T cells (2-week vs. 7-week: spleen 13.2% vs. 9.3%, tumor 4.8% vs. 2.5%). HE results demonstrated that the tumor tissues in PDX models maintained a high degree of morphological similarity to the primary tumors in both NSG and huHSC-NCG-hIL15 mouse models. Conclusion:The HNSCC PDX modeling protocol demonstrates operational feasibility and high reproducibility, establishing this model as a robust platform for mechanistic and immunotherapeutic studies.

China emerges as a major country in nuclear energy development and the application of nuclear and radiologic technology. The diagnosis and treatment of acute radiation syndrom (ARS) caused by external irradiation represent a core function in the country′s medical rescue of nuclear and radiological emergencies. Clinically, ARS manifests hematopoietic, gastrointestinal, cutaneous, and central nervous system syndromes, with specific clinical manifestations, signs, severity, and prognosis strongly correlated with radiation dose. China has established a number of national and provincial centers for treating radiation-induced damage. Nevertheless, most medical staff have limited experience in ARS treatment. This consensus presents a summary of recent experience in treating ARS of China. In combination with recommendations from international organizations such as the World Health Organization (WHO), this consensus proposes key evidence of critical clinical issues of ARS, covering all links in the rescue of external irradiation-induced ARS. Initially, clinical diagnosis, syndromes, and severe degrees should be determined based on clinical symptoms and dose estimates. It is necessary to normalize clinical treatment measures for hematopoietic recovery, gastrointestinal injury treatment, infection control, symptomatic treatment, and multi-organ function preservation. To this end, this consensus offers cautions. This consensus provides principles of treatment with traditional Chinese medicine, psychological intervention, and follow-up. Additionally, it highlights multidisciplinary collaboration. It is recommended that this consensus be applied in relevant treatment centers.

Objective To analyze the evaluation value of basilar artery curvature based on compu-ted tomography angiography for the long-term prognosis of elderly patients with pontine infarc-tion.Methods A retrospective analysis was conducted on 98 elderly patients with pontine infarc-tion admitted in Guangyuan Hospital of Traditional Chinese Medicine from September 2020 to September 2023.According to the prognosis status,they were divided into good prognosis group(n=61)and poor prognosis group(n=37).The computed tomography angiography parameters of basilar artery curvature were compared between the two groups to analyze the correlation with long-term prognosis of patients.The predictive values of these parameters in predicting the prog-nosis was assessed.Results The poor prognosis group had significantly smaller diameter of basi-lar artery,longer length in basilar artery curvature,and larger curvature index than the good prog-nosis group(P＜0.01).The diameter of basilar artery was negatively correlated,and the length in basilar artery curvature and the curvature index were positively correlated with poor prognosis in the elderly patients with pontine infarction(P＜0.01).The length of the basilar artery curvature and the curvature index were risk factors for poor prognosis in elderly patients with pontine infarction(P＜0.01).The diameter of the basilar artery was a protective factor for poor prognosis in elderly patients with pontine infarction(P＜0.01).ROC curve analysis indicated that the area under curve value of combined above three computed tomography angiography parameters of bas-ilar artery curvature in predicting the long-term prognosis of elderly patients with pontine infarc-tion was 0.938(95％CI:0.870～0.977),with a sensitivity of 94.59％and a specificity of 75.41％.Conclusion computed tomography angiography can evaluate the degree of basilar artery curva-ture,intuitively reflect the morphological characteristics of basilar artery,and provide imaging ba-sis for predicting the long-term prognosis of elderly patients with pontine infarction.

The connotation of the "four-dimensional pivot-earth" qi transformation mode is a dialectical system of the ascending and descending of yin-yang qi movement， which presented as "the middle Jiao showing earth qi mediating， the left wheel showing water and wood ascending， and the right wheel showing fire and metal converting and descending". Based on this dialectical thinking， it is believed that the core pathogenesis of myasthenia gravis is deficiency of center qi and transportation failure to pivot-earth； the middle-stage characteristics of the disease progression are the loss of mediation of the central qi， resulting in water coldness and wood constraint， and clear yang failing to ascend； the final outcome of this disease is the loss of astringeing of lung metal and qi sinking. The treatment should be based on the rule of qi movement， so for the start-stage， Buzhong Yiqi Decoction （补中益气汤） should be used as the basis to nourish the earth and consolidate the root， and restrengthen the middle qi； for the middle-stage， herbs like Yingyanghuo （Epimedium brevicornu Maxim.）， Bajitian （Morinda officinalis How） could be combined to warm the water and soothe the wood， raise yang and boost qi； for the final stage， plus Sini Decoction （四逆汤） to astringe metal to stop collapse， and powerfully supplement original qi. All these medicinals can promote pivot-earth re-transportation， four-dimensional transformation， and regular circulation of qi movement， so as to provide thoughts for improving the clinical effectiveness of myasthenia gravis.

Objective To investigate the expression of Delta(24)-cholesteryl reductase(DHCR24)proteins in cervical squamous intraepithelial lesions(SILs)tissues and its value in different cervical lesion patho-logical diagnosis.Methods The expression of DHCR24,p16,and Ki-67 was quantitatively detected by immuno-histochemistry in 51 normal cervical tissues,44 LSILs,and 57 HSILs.The receiver operating characteristic(ROC)curve was drawn to analyze the diagnostic efficacy of DHCR24,p16,and Ki-67 proteins in evaluating the degree of SILs.Results The expression levels of DHCR24,p16 and Ki-67 protein were positively correlated with the progression of SILs(P<0.05).ROC analysis showed that the immunohistochemistry score cutoff value for DHCR24 between normal cervical tissue and LSIL was 0.1145,and between LSIL and HSIL was 0.1969.The sensi-tivity of DHCR24 in diagnosing LSIL was 79.55%,higher than that for p16 and Ki-67,which was 15.91%and 18.08%(P<0.05).The area under the ROC curve(AUC)for distinguishing normal cervical tissue from LSIL using a combination of DHCR24 and p16 was 0.932(95%CI:0.878～0.986),higher than that for p16 and Ki-67 combined,which was 0.861(95%CI:0.785～0.936).The AUC for distinguishing LSIL from HSIL using a combi-nation of DHCR24 and p16 was0.971(95%CI:0.946～0.997),higher than that for p16 and Ki-67 combined,which was 0.870(95%CI:0.790～0.949).Conclusions Both DHCR24 and p16 protein expression levels can pro-vide reference for the grading of SILs,and their combination can improve the diagnostic efficiency.The cutoff value derived from the ROC curve plotted by DHCR24 immunohistochemical staining intensity can improve the sensitivity of LSIL diagnosis.

Objective To compare the effect of different intensity of neuromuscular training(NMT)on muscle strength and knee joint function of patients after anterior cruciate ligament reconstruction(ACLR).Methods From January,2023 to January,2024,60 ACLR patients in Changhai Hospital were selected,and they received the same intensity of NMT from one to eight weeks after surgery.Eight weeks after surgery,they were randomly divided into low intensity group(n=30)and high intensity group(n=30),and then they received different inten-sities of NMT from nine to 16 weeks after surgery,each training session lasted one hour,with three sessions per week,totaly 48 sessions.The Lysholm score,knee flexor and extensor muscle strength and muscle endurance-were compared at eight weeks and 16 weeks after surgery.Results After group training,the Lysholm score significantly increased in both groups(|t|>13.739,P<0.001),and was higher in the high intensity group than in the low intensity group(t=-2.574,P<0.05);in the high intensity group,the relative peak torque and endurance of the extensor and flexor muscles improved at angular velocities of 60°/s,120°/s and 180 °/s(|t|>2.320,P<0.05);in the low intensity group,the flexor peak torque improved at all the three angular velocities(t>2.177,P<0.05),the extensor peak torque improved at angular velocities of 60°/s and 180°/s(|t|>1.715,P<0.05),and the extensor endurance improved at angular velocity of 60°/s(t=-2.293,P<0.05).However,there was no significant difference in the relative peak torque and endurance of the extensor and flexor muscles at all the three angular velocities(P>0.05).Conclusion Both high and low intensity NMT could improve the muscle strength,muscle endurance and knee joint func-tion.Maybe,high intensity is superior to low intensity.Further verification is still needed.
