Health economics evidence plays an important role in linking clinical value evidence with health resource allocation decisions in the development of clinical practice guidelines. It can not only effectively balance clinical effectiveness and economic feasibility but also avoid forming "idealized" recommendations that are detached from the affordability of the healthcare system or the burden-bearing capacity of patients. To promote guideline developers to use health economics evidence more standardizedly and fully, this paper conducts an in-depth analysis of the current application status, existing challenges, access channels, and application processes of health economics evidence in current guidelines, and on this basis, puts forward considerations and suggestions for strengthening and standardizing the application of health economics evidence in China's clinical practice guidelines.

Objective To explore the effect of hyperbaric oxygen combined with synchronous brain bionic electrical stimulation on patients with stroke-related sleep disorders.Methods From November,2023 to November,2024,a total of 68 stroke patients with stroke-related sleep disorders ad-mitted to Huashan Hospital,Fudan University were selected.They were randomly divided into control group(n=34)and experimental group(n=34).The control group received routine hyperbaric oxygen therapy,while the ex-perimental group received routine hyperbaric oxygen therapy combined with synchronous brain bionic electrical stimulation inside the chamber,for four weeks.Pittsburgh Sleep Quality Index(PSQI),sleep-monitoring wrist-bands,Self-rating Anxiety Scale(SAS)and Self-rating Depression Scale(SDS)were used to assess the outcomes before and after treatment..Results Four patients in the control group and one in the experimental group dropped out.After treatment,the scores of each factors of PSQI decreased in both groups(t>2.693,P<0.05),and were lower in the experimental group than in the control group(t>2.699,P<0.01),expect hypnotic drug use(P>0.05);the total sleep time,deep sleep time and rapid eye movement sleep time became longer in both groups(|t|>7.270,P<0.001),and they were longer in the experimental group than in the control group(|t|>5.712,P<0.001);the scores of SAS and SDS decreased in both groups(t>9.530,P<0.001),and they were less in the experimental group than in the control group(t>4.740,P<0.001).Conclusion Synchronous brain bionic electrical stimulation in hyperbaric oxygen chamber could effectively prolong the total sleep time,deep sleep time and rapid eye movement time of patients with stroke-related sleep disorders,re-lieve anxiety and depression after stroke,and improve sleep quality.

Objective To explore the effects and mechanism of finasteride on epithelial mesenchymal transition in bladder urothelial carcinoma.Methods T24 human bladder cancer cells were treated with different concentrations of finasteride(0.1%,0.5%,and 1%)for 24 hours,with untreated T24 cells as the control group.Some cells were subjected to hypoxic conditions(1%O2)to mimic a low-oxygen microenvironment.Cell proliferation was assessed by immunofluorescence staining for Ki-67.Apoptosis rates were evaluated using Annexin V-FITC/PI double staining followed by flow cytometry,and cell migration was analyzed via scratch wound assays.Western blot was used to detect the expression of EMT-related proteins such as HIF-1α,E-cadherin,N-cadherin,and Vimentin.To further validate the role of the HIF-1α pathway in finasteride's anti-tumor effects,a HIF-1α overexpression lentiviral vector(MOP-1)was constructed and transfected into T24 cells.For animal experiment,T24 tumor-bearing nude mice were randomly divided into four groups:control,MOP-1,1%finasteride,and 1%finasteride+MOP-1(n=4 per group).After 4 weeks of continuous oral administration,tumor growth,metastasis,and perihepatic lymph node changes were recorded,and histological analysis was performed using H&E staining.Results Finasteride affects the proliferation,apoptosis,and epithelial-to-mesenchymal transition of T24 cells in a concentration-dependent manner.Compared to the control group,finasteride-treated T24 cells showed a reduced number of cells in the growth phase,decreased migration,increased expression of epithelial markers,and decreased expression of mesenchymal markers(P<0.05).In T24 cells exposed to hypoxic conditions,the expression of HIF-1α pathway markers was significantly increased(P<0.05),while 1%finasteride treatment inhibited the HIF-1α pathway(P<0.05).The HIF-1α pathway expression level in the 1%finasteride and HIF-1α overexpression plasmid group was lower than that in the control group(P<0.05).Additionally,the tumor mass-to-body weight ratios were lower,with the number of bladder cancer metastases to the liver decreased(P<0.05).Conclusion Finasteride can effectively block the growth of bladder cancer and the transition of epithelial cells into mesenchymal cells by inhibiting HIF-1α/Snail expression.

Cemental tear is a rare and indetectable condition unless obvious clinical signs present with the involvement of surrounding periodontal and periapical tissues. Due to its clinical manifestations similar to common dental issues, such as vertical root fracture, primary endodontic diseases, and periodontal diseases, as well as the low awareness of cemental tear for clinicians, misdiagnosis often occurs. The critical principle for cemental tear treatment is to remove torn fragments, and overlooking fragments leads to futile therapy, which could deteriorate the conditions of the affected teeth. Therefore, accurate diagnosis and subsequent appropriate interventions are vital for managing cemental tear. Novel diagnostic tools, including cone-beam computed tomography (CBCT), microscopes, and enamel matrix derivatives, have improved early detection and management, enhancing tooth retention. The implementation of standardized diagnostic criteria and treatment protocols, combined with improved clinical awareness among dental professionals, serves to mitigate risks of diagnostic errors and suboptimal therapeutic interventions. This expert consensus reviewed the epidemiology, pathogenesis, potential predisposing factors, clinical manifestations, diagnosis, differential diagnosis, treatment, and prognosis of cemental tear, aiming to provide a clinical guideline and facilitate clinicians to have a better understanding of cemental tear.

Objective:To evaluate a novel self-designed elbow flexion-extension axis guide that is easy to operate, accurately positioned, and X-ray-free.Methods:This study collected the elbow joint CT scans from 60 normal adults [40 males and 20 females with an age of (38.1±9.3) years] at Department of Orthopedics, The Third Hospital of Xiamen between September and December 2024. The scan images were imported into 3D modeling software for systematic measurement of key anatomical parameters of the distal humerus. The structural design of a novel elbow flexion-extension axis guide was completed based on these measurements, combined with the anatomical data of the distal humerus reported in 6 relevant articles between January 2008 and December 2024 retrieved from the CNKI and PubMed databases. After physical models of the distal humerus from the 60 healthy adults were fabricated using 3D printing technology, they were divided into 2 even groups: a guide-assisted group ( n=30) where the positioning needle was inserted with the assistance of the elbow flexion-extension axis guide and a conventional group ( n=30) where the positioning needle was inserted freehand. The entry deviation, exit deviation, inter-axial angle, inter-axial distance, operation time, and fluoroscopic verifications in positioning of elbow flexion-extension axis were compared between the 2 groups. Results:The guide-assisted group demonstrated significantly smaller values than the conventional group in entry deviation [(1.52±0.70) mm versus (2.29±1.00) mm], exit deviation [(2.83±1.49) mm versus (4.95±1.63) mm], inter-axial angle (3.46°±0.93° versus 6.45°±1.21°), and operation time [(92.0±17.0) s versus (509.5±42.3) s] (all P<0.05). The conventional group required an average of (10.7±2.1) fluoroscopic verifications, while the guide-assisted group eliminated radiation exposure. No statistically significant difference was observed in the inter-axial distance between the 2 methods in positioning of elbow flexion-extension axis ( P>0.05). Conclusion:As the novel self-designed elbow flexion-extension axis guide can improve accuracy in positioning the elbow flexion-extension axis without requiring fluoroscopy, it significantly shortens intraoperative positioning time, and is handy to use.

Knee osteoarthritis is a common joint disease within osteoarthritis,characterized by pain,swelling,and limited functionality as the main clinical manifestations.In severe cases,it affects daily life and falls under the category of"impediment syndrome"or"bone impediment"in TCM.The author believes that the theory of"bones,tendons,and muscles"is closely related to this disease.Treatment should focus on simultaneously nourishing the liver,spleen and kidneys,considering tendons,bones and muscles,while also dispelling wind,cold and dampness.The clinical application of Sanbi Decoction has shown good efficacy,and this discussion aimed to provide ideas for the diagnosis and treatment of knee osteoarthritis.

Objective To construct the respiratory rehabilitation calisthenics for school-age children with asthma,and evaluate its effects,in order to provide a guidance for the scientific and effective implementation of respiratory rehabilitation in clinical work.Methods By convenience sampling method,the school-age children with asthma treated in the respiratory outpatient department of a tertiary specialized children's hospital in Chongqing from De-cember 2023 to February 2024 were selected.The children were randomly divided into an experimental group and the control group(25 of each group)by a random number table.Both groups were given routine asthma drug in-halation treatment and health education.Additionally,the experimental group received respiratory rehabilitation calis-thenics training and the control group received conventional aerobic exercise training.After 3-month intervention,the effects of adherence to respiratory rehabilitation training,lung functions,exercise capacity,inspiratory muscle strength and occurrence of adverse events were evaluated between 2 groups.Results 24 children of each group completed the study.After 3-month intervention,the adherence to respiratory rehabilitation training,exercise capacity and in-spiratory muscle strength were improved in the experimental group compared with those in the control group,and all differences were statistically significant(P＜0.05).There were no adverse events in both groups.Conclusion The respiratory rehabilitation calisthenics for school-age children with asthma constructed in this study was scientif-ic,feasible and safe,and could improve exercise capacity and inspiratory muscle strength for children with asthma.

OBJECTIVE: To investigate the effect of moxibustion on central insulin resistance related proteins of the rats suffering from diabetic cognitive decline, and analyze the underlying mechanism of moxibustion for cognition improvement. METHODS: Using the intraperitoneal injection of STZ combined with a high-fat diet, the rat model of diabetic cognitive decline were prepared. Twenty successfully-modeled rats were assigned randomly into a model group and a moxibustion group, 10 rats in each one. Besides, a blank group was set up with 10 rats collected. In the moxibustion group, suspending moxibustion was applied to "Baihui" (GV20), "Shenting" (GV24) and "Dazhui" (GV14) at the same time, 20 min in each intervention, once a day, and 6 interventions were delivered weekly and the duration of treatment was consecutive 4 weeks. The random blood glucose was measured using glucometer, and the learning-memory ability was detected by water maze test. HE staining was used to observe the morphology of neurons in the hippocampal tissue, real-time PCR assay was to detect mRNA expression of insulin receptor substrate 1 (IRS1), phosphatidylinositol 3-kinase (PI3K) and protein kinase B (AKT) in the hippocampal tissue. The Western blot method was employed to detect the protein expression of IRS1, PI3K, AKT, phosphorylated IRS1 (p-IRS1), phosphorylated PI3K (p-PI3K) and phosphorylated AKT (p-AKT) in the hippocampal tissue, and the ratio of p-IRS1/IRS1, p-PI3K/PI3K and p-AKT/AKT was calculated separately. The immunofluorescence intensity of p-IRS1, p-PI3K, and p-AKT was measured using immunofluorescence. RESULTS: Compared with the blank group, the rats of the model group exhibited higher random blood glucose (P<0.001), longer escape latency (P<0.001), severe pathological damage in the hippocampus, lower mRNA expression of IRS1, PI3K, and AKT (P<0.001), reduced ratio of p-IRS1/IRS1, p-PI3K/PI3K and p-AKT/AKT (P<0.001), and declined immunofluorescence intensity of p-IRS1, p-PI3K, and p-AKT in the hippocampal tissue (P<0.001). In comparison with the model group, for the rats of the moxibustion group, the random blood glucose decreased (P<0.05), the escape latency was shortened (P<0.01), the hippocampal pathological damage was attenuated, the mRNA expression of IRS1, PI3K and AKT increased (P<0.01), the ratio of p-IRS1/IRS1, p-PI3K/PI3K and p-AKT/AKT was elevated (P<0.01, P<0.05), and the immunofluorescence intensity of p-IRS1, p-PI3K, and p-AKT in the hippocampal tissue was strengthened (P<0.01, P<0.05). CONCLUSION In diabetic rats experiencing cognitive decline, moxibustion can enhance the learning-memory ability, which may be attributed to modulating the protein expression of IRS1, PI3K, and AKT, and their phosphorylation, activating insulin signal transduction, and reducing central insulin resistance.
