OBJECTIVE To explore a model for constructing a platform for medical institution formulation and provide insights for promoting their development. METHODS By systematically reviewing the development status and challenges of medical institution preparations in China， and based on the theory of industry-university-research collaborative innovation， the organizational structure， collaborative processes， and safeguard mechanisms of the platform were designed. RESULTS & CONCLUSIONS Medical institution formulations in China mainly faced challenges such as weak research and development （R&D） capacity， uneven quality standards， and blocked transformation pathways. This study established a full-chain， whole- industry collaborative innovation network covering the government， medical institutions， universities/research institutes， pharmaceutical enterprises， and the market， forming a new “government-industry-university-research-application” five-in-one platform model for medical institution formulations. By establishing mechanisms such as multi-entity collaborative cooperation， full- chain intellectual property management， contribution-based benefit distribution， staged risk-sharing， and third-party evaluation， the model clarified the responsibilities and collaborative pathways of all parties. The new model highlights the whole-process transformation of clinical experience-based prescriptions， enabling precise alignment between clinical needs and technological R&D， as well as between preparation achievements and industrial transformation. While breaking down the barriers of traditional platform construction， it effectively achieves optimal resource allocation and complementary advantages， addresses problems emerging in the development of medical institution preparations， and provides reference value for the formulation of relevant systems.

Objective:In the context of China's cardiovascular disease(CVD)high-risk population screening and intervention project,this study systematically evaluates the applicability of the EQ-5D-5L and SF-6Dv2 instruments among individuals at high risk of CVD.Methods:Convergent validity was assessed using Spearman's correlation coefficient.Measurement agreement was evaluated through intraclass correlation coefficients(ICC)and Bland-Altman plots.Factors influencing utility differences were explored using multiple linear regression analysis.Kruskal-Wallis test and t-test were used to examine discriminant validity.Sensitivity was compared by effect size(ES),relative efficiency(RE),and the area under the receiver operating characteristic curve(ROC-AUC).Floor and ceiling effects were also compared.Results:Among 5,415 individuals at high risk of CVD,the two instruments showed moderate overall correlation and acceptable convergent validity,but dimension-specific correlations were weak,and measurement consistency was low(ICC=0.367).Both instruments effectively distinguished different health states,yet the SF-6Dv2 demonstrated superior sensitivity and a milder ceiling effect.Conclusion:When measuring the health utility value of CVD patients,scale selection should be cautious,especially for high-risk groups,and SF-6Dv2 is more appropriate.

AIM To prepare the sustained-release microspheres of ginsenosides.METHODS The sustained-release microspheres were prepared by SPG membrane emulsification technology with poly(lactic-co-glycolic acid)(PLGA)as a shell carrier.With PLGA concentration,feed rate and Span 60 concentration as influencing factors,comprehensive score for appearance,drug loading and encapsulation efficiency as an evaluation indice,the preparation process was optimized by response surface method.The morphology of sustained-release microspheres was observed,after which the particle size,drug loading and encapsulation efficiency were determined,and the in vitro drug release was investigated.RESULTS The optimal conditons were determined to be 45 s for agitation time of primary emulsion,74.68 mg/mL for PLGA concentration,11％for feed rate,and 4.18 mg/mL for Span 60 concentration,the comprehensive score was 74.98.The round sustained-release microspheres demonstrated the average particle size of 4.33 μm,drug loading of(8.24±0.13)％,and encapsulation efficiency of(74.94±1.17)％,respectively.At 336 h,ginsenosides Rg1,Rb1,Rb2 displayed the accumulative release rates of 84.12％,78.04％,65.88％,respectively.CONCLUSION This reasonable and feasible method can be used for the preparation of sustained-release microspheres of ginsenosides with good appearance and high drug loading,which can provide references for the preparation of other water-soluble drug microspheres and solution of microsphere collapse problem.

Objective:To observe the effect of long-term follow-up of cerebral aneurysm embolization and to explore the related factors of aneurysm recurrence.Methods:A total of 142 cases of intracranial aneurysm rupture embolization patients treated in the Yuebei People′s Hospital from August 2000 to August 2013 were selected as the study objects. All of them underwent embolization treatment, and digital subtraction angiography (DSA), CT angiography (CTA) and magnetic resonance angiography (MRA) were performed after surgery. The follow-up period was 10 years, and the long-term outcome was evaluated using the Stroke Modified Rankin Scale (mRS) score. The results of immediate postoperative angiography and long-term follow-up in different embolization groups were analyzed. The risk factors of recurrence after ruptured cerebral aneurysm embolization were analyzed by single factor and independent risk factors were analyzed by multiple factor.Results:Of 142 patients (161 aneurysms), 106 were embolized by simple embolization and 55 were embolized by stent-assisted embolization. There was no significant difference in the results of immediate embolization between simple embolization and stent assisted embolization ( P>0.05). The proportion of giant aneurysms in the stent-assisted embolization group was higher than that in the simple embolization group ( P<0.05). Follow-up results showed that among the 142 patients, 106 had mRS score 0, 27 had mRS score 1, 5 had mRS score 2, and 4 had mRS score 4. The good clinical prognosis rate was 93.7%(133/142). Of the 161 aneurysms, 36 recurred, with a recurrence rate of 22.4%(36/161). Univariate analysis showed that aneurysm size, cervical tumor and embolization degree were risk factors for cerebral aneurysm recurrence (all P<0.05). The results of multi-factor analysis showed that aneurysm size was an independent risk factor for cerebral aneurysm recurrence ( P<0.05). Conclusions:The long-term follow-up after embolization of cerebral aneurysms is good, but cerebral aneurysms still have the possibility of recurrence. Aneurysm size is an independent risk factor for aneurysm recurrence. Timely detection of cerebrovascular changes can be treated in time to avoid cerebrovascular accidents.

Oropharyngeal squamous cell carcinoma(OPSCC)is a malignant tumor originating from the squamous epithelium of the oro-pharyngeal mucosa,accounting for more than 90％of oropharyngeal malignancies.In recent years,human papillomavirus(HPV)infec-tion has become one of the primary etiological factors of oropharyngeal squamous carcinoma.The incidence of HPV-associated oropharyn-geal squamous carcinoma has been rising annually,with a noticeable trend toward younger populations,posing a significant threat to hu-man health.Due to the distinct biological behavior and clinical characteristics of HPV-associated oropharyngeal squamous carcinoma com-pared to its non-HPV-related counterpart,the diagnostic and treatment strategies for oropharyngeal squamous carcinoma have undergone substantial changes.Prevention and screening for oropharyngeal squamous carcinoma are of critical importance.The diagnostic and treat-ment process involves multi-disciplinary collaboration,including oral and maxillofacial surgery,otolaryngology,head and neck surgery,oncology,radiology and pathology.Based on evidence from clinical practice,a comprehensive,integrated diagnostic and therapeutic ap-proach has been established,centered around the concept of"prevention,screening,diagnosis,treatment,and rehabilitation",covering the entire patient lifecycle and providing a valuable reference for clinical practice.

Objective To explore the molecular mechanism by which SOS Ras/Rac guanine nucleotide exchange factor 1-intronic transcript 1(SOS1-IT1)affects enhancer of zeste homolog 2(EZH2)protein expression in endometrial cancer cells Ishikawa and RL95-2.Methods Lentiviral transfection of short hairpin RNA(shRNA)and overexpression plasmid were used in Ishikawa and RL95-2 cell lines to knock down and overexpress SOS1-IT1.The mechanism of EZH2 expression regulation was studied using Real-time PCR,Western blotting,and chromatin immunoprecipitation.Results The expression of SOS1-IT1 and EZH2 genes was positively correlated in endometrial cancer tissues.Knocking down SOS1-IT1 significantly reduces the expression of EZH2,inhibited the proliferation and migration of Ishikawa and RL95-2 cells,and could reduced the acetylation of histone H3 at position 27(H3K27)and the enrichment of CREB binding protein(CBP)in the EZH2 gene promoter region.Overexpression of SOS1-IT1 could increased the expression of EZH2 and enhance the acetylation of H3K27 and the enrichment of CBP.CBP could bind to SOS1-IT1 RNA,and this binding ability was weakened when CBP was knocked down.Conclusion SOS1-IT1 can promote the expression level of EZH2 in endometrial cancer cells Ishikawa and RL95-2 by regulating the acetylation modification level of the EZH2 gene promoter region,thereby affecting the proliferation and migration ability of endometrial cancer cells.

Objective To evaluate the patterns of sleep duration by integrating nocturnal and daytime sleep,and to explore their asso-ciations with activities of daily living(ADL)in middle-aged and older adults.Methods The data of sleep and ADL were obtained from 11 085 subjects aged 45 and older,which were collected from the China Health and Retirement Longitudinal Study(CHARLS).At enrollment in 2011,data on nocturnal and daytime sleep duration were collected through questionnaires.Firstly,subjects were divided into three groups based on the 33rd and 66th percentiles of nocturnal sleep duration,assigned scores of 1,2 and 3,respectively.Subsequently,subjects were divided into three groups based on the 33rd and 66th percentiles of daytime sleep du-ration,assigned scores of 3,2 and 1,respectively.Finally,the scores for nocturnal and daytime sleep were summed to create a total sleep score ranging from 2 to 6.A total sleep score of 6 was defined as sleep duration pattern 1,indicating a longer nocturnal sleep duration with no or shorter daytime sleep duration.Similarly,total sleep scores of 5,4,3 and 2 were defined as sleep duration patterns 2,3,4 and 5,respectively,with sleep duration pattern 5 indicating a shorter nocturnal sleep duration and a longer daytime sleep duration.The status of ADL was assessed using the Activities of Daily Living Scale(Katz edition)at baseline and during follow-up in 2013,2015 and 2018.The association between sleep duration patterns and the risk of ADL disability was evaluated us-ing a Cox proportional hazards model.Results A total of 63 015 person-years were followed,with 11 085 subjects,during which 3 239 individuals experienced ADL disability.The 33rd and 66th percentiles of the nocturnal sleep duration in the study population were 6.00 hours and 7.00 hours,respectively;while the 33rd and 66th percentiles of the daytime sleep duration were 0.00 hours and 1.00 hours,respectively.Of those,1 522 were classified into sleep duration pattern 1,2 196 into sleep duration pattern 2,4 299 into sleep duration pattern 3,2 304 into sleep duration pattern 4,and 764 into sleep dura-tion pattern 5.Compared to sleep duration pattern 1,the risk of ADL disability of patterns 3,4 and 5 were higher(P<0.05),with P-value for the trend less than 0.001,after adjusting for age,sex,body mass index,marital sta-tus,educational level,residence,smoking,drinking,history of chronic diseases,depression status and season.No interaction effect between gender,age and season,and sleep duration patterns was observed(P>0.05).Com-pared to subjects with nocturnal sleep duration≥9 hours and daytime sleep duration<2 hours,those with noctur-nal sleep duration<7 hours and daytime sleep duration≥2 hours had a higher risk of ADL disability(P<0.05).Conclusion Older adults who sleep less at night but take longer naps during the day are at a higher risk of experiencing limitations in their ADL.Sleep patterns may influence ADL among middle-aged and older populations,and man-aging their sleep duration patterns could help prevent the onset of ADL limitations.

This consensus was developed by the Orthodontic Society of the Chinese Stomatological Association to provide a systematic, scientific, and practical guideline for informed consent in orthodontic care. Orthodontic treatment is typically lengthy, highly individualized, and involves multiple factors such as growth and development, occlusal function, and facial esthetics. Rapid technological advances and diverse risk profiles make the traditional reliance on orthodontist experience or institutional templates insufficient to ensure patients′ full understanding and autonomous decision-making. To address this, the expert panel conducted extensive reviews of domestic and international guidelines, analyzed representative dispute cases, and performed multicenter patient-clinician surveys. Using a multi-round Delphi method, the group established a standardized informed consent framework covering the initial consultation, treatment, and retention phases. The consensus emphasizes that informed consent is not only a fundamental legal and ethical requirement but also a key step in building trust, improving patient compliance, and enhancing treatment satisfaction. Orthodontists should clearly and comprehensively explain treatment plans, potential risks, uncertainties, and associated costs, while respecting the autonomy of patients or guardians, and maintain continuous communication and dynamic evaluation throughout the treatment process. The release of this consensus provides unified and authoritative guidance for clinical orthodontics, helping to standardize informed consent, enhance its transparency, safeguard patient rights, reduce medical risks, and promote high-quality, sustainable development of orthodontic practice.

Oral squamous cell carcinoma(OSCC)is a malignant lesion originating from the oral mucosal squamous epithelium,account-ing for over 80％of oral and maxillofacial malignancies.Key etiological factors include tobacco,alcohol abuse,and betel quid chewing.In China,its incidence has shown an overall upward trend,posing a significant threat to public health.OSCC exhibits high local invasive-ness,making early diagnosis critical for improving prognosis.Its clinical management requires close multidisciplinary collaboration among oral and maxillofacial surgery,head and neck surgery,radiation oncology,medical oncology,reconstructive surgery,radiology,patholo-gy,and nutritional support teams.Given the increasing disease burden of OSCC and rapid development of multidisciplinary collaborative models,an expert panel has formulated this integrated management consensus based on evidence-based medicine and extensive deliber-ation.Centered on the'Prevention-Screening-Diagnosis-Treatment-Rehabilitation'framework,the consensus provides comprehensive guidance for the entire disease course of OSCC patients,aiming to standardize clinical practice.
