1.Expert recommendations on vision friendly built environments for myopia prevention and control in children and adolescents
Chinese Journal of School Health 2026;47(1):1-5
Abstract
The prevention and control of myopia in Chinese children and adolescents has become a major public health issue. While maintaining increased outdoor activity as a cornerstone intervention, there is an urgent need to explore new complementary approaches that can be effectively implemented in both indoor and outdoor settings. In recent years, environmental spatial frequency has gained increasing attention as one of the key environmental factors influencing the development and progression of myopia. Both animal studies and human research have confirmed that indoor environments lacking mid to high spatial frequency components, often characterized as "visually impoverished", can promote axial elongation and myopia through mechanisms such as disruption of retinal neural signaling, impaired accommodative function, and altered expression of related molecules. Based on the scientific consensus, it is recommended that "enriching of environmental spatial frequency" should be integrated into the myopia prevention and control framework. Following the principles of schoolled organization, family cooperation, community involvement, and student participation, specific measures are put forward in three areas:optimizing school visual settings, improving home spatial environments, and promoting healthy visual behavior. The aim is to create "visually friendly" indoor environments as an important supplement to outdoor activity, thereby providing a novel perspective and strategy for comprehensively advancing myopia prevention and control among children and adolescents.

ObjectiveTo explore the effect of the medical-community linkage model on activities of daily living, psychological status and motor function of stroke patients in the community. MethodsA total of 60 stroke patients admitted to two community health service centers and their affiliated stations in Fengtai District, Beijing, from January, 2024 to August, 2025 were enrolled and randomly divided into control group (n = 30) and intervention group (n = 30). The control group received routine medicine, dietary care and rehabilitation management, while the intervention group underwent rehabilitation with the medical-community linkage model, for twelve weeks. They were assessed with modified Barthel Index (MBI), Hamilton Anxiety Scale (HAMA), Hamilton Depression Scale (HAMD) and Fugl-Meyer Assessment (FMA) before and after intervention. ResultsAfter intervention, the MBI, HAMA, HAMD and FMA scores of patients improved in both groups (|t| > 5.599, P < 0.001), and improved more in the intervention group than in the control group (P < 0.05), except MBI. The HAMA and HAMD scores of family members decreased in both groups (|t| > 10.333, P < 0.001), and decreased more in the intervention group than in the control group (t > 5.681, P < 0.001). ConclusionThe medical-community linkage model can further improve the motor function of stroke patients in community, as well as the psychological status of both patients and their family members.

ObjectiveTo define hyaluronidase treatment parameters that efficiently remove the extracellular matrix from zygotes without impairing embryo development, thereby providing a basis for standardized assisted reproductive procedures. MethodsMouse zygotes were treated with hyaluronidase at 40, 80, or 120 IU/mL for 60, 90, or 120 s. Following treatment, embryos were cultured in Krebs-ringer bicarbonate-based solution for organismal media (KSOM) medium, and blastocyst formation was monitored using a Time-lapse imaging system. ResultsA concentration of 40 IU/mL was insufficient for effective matrix removal, whereas 120 IU/mL markedly reduced blastocyst formation. In contrast, 80 IU/mL achieved efficient matrix clearance with minimal impact on development. Blastocyst rates were comparable between the 60 s and 90 s groups, with a slight advantage for the 60 s under the experimental conditions. ConclusionHyaluronidase treatment at 80 IU/mL for 60 s represents optimal processing conditions for mouse zygotes. These findings provide experimental basis and standardized reference for embryo handling in assisted reproductive technologies.

ObjectiveBased on ultra-performance liquid chromatography-quadrupole-electrostatic field orbitrap high resolution mass spectrometry(UPLC-Q-Orbitrap-MS), the chemical constituents of Qili Qiangxin capsules was identified, and their distribution in vivo was analyzed. MethodsUPLC-Q-Orbitrap-MS was used to detect the sample solution of Qili Qiangxin capsules, as well as the serum, brain, heart, lung, spleen, liver and kidney tissues of mice after oral administration. Using the Thermo Xcalibur 2.2 software, the compound information database was constructed, and the molecular formulas of compounds corresponding to the quasi-molecular ions were fitted. Based on the information of retention time, accurate relative molecular mass and fragments, the compounds and their distribution in vivo were analyzed by comparing with the data of reference substances and literature. ResultsA total of 233 compounds, including 70 terpenoids, 60 flavonoids, 23 organic acids, 17 alkaloids, 20 steroids, 7 coumarins and 36 others, were identified or predicted from Qili Qiangxin capsules, 73 of which were identified matching with standard substances. Tissue distribution results showed that 71, 17, 38, 33, 32, 58 and 43 migrating components were detected in blood, brain, heart, lung, spleen, liver and kidney, respectively. Thirty-seven components were absorbed into the blood and heart, including quinic acid, benzoylaconitine benzoylmesaconine and so on. Fourteen components were absorbed into the blood and six tissues, including calycosin, methylnissolin, formononetin, alisol B, alisol A and so on. ConclusionThis study comprehensively analyzes the chemical components of Qili Qiangxin capsules and their distribution in vivo. Among them, astragaloside Ⅳ, salvianolic acid B, ginsenoside Rb1, ginsenoside Rb3, ginsenoside Rd, ginsenoside Rg3, calycosin-7-glucoside, and sinapine may be the important components for the treatment of heart failure, which can provide useful reference for its quality control and research on pharmacodynamic material basis.

ObjectiveTo investigate the effects of modified Ditan tang on genes related to the transcription-translation feedback loop (TTFL) of biorhythm in the rat model of non-alcoholic fatty liver disease (NAFLD) and its mechanism for prevention and treatment of NAFLD. MethodsSixty-five healthy SPF male SD rats were randomly assigned into blank (n=20), model (n=15), and low-, medium-, and high-dose (2.68, 5.36, and 10.72 g·kg-1·d-1, respectively) modified Ditan tang (n=10) groups. Other groups except the blank group were fed a high-fat diet for 12 weeks. The modified Ditan tang groups were treated with the decoction at corresponding doses by gavage, and the blank and model groups were treated with an equal volume of normal saline from the 9th week for 4 weeks. The levels of triglyceride (TG), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), aspartate aminotransferase (AST), and alanine aminotransferase (ALT) in the serum were measured by an automatic biochemical analyzer. TG and non-esterified fatty acid (NEFA) assay kits were used to measure the levels of TG and NEFA in the liver. The pathological changes in the hypothalamus and liver were observed by hematoxylin-eosin staining, and the lipid deposition in the liver was observed by oil red O staining. The levels of brain-muscle ARNT-like protein 1 (BMAL1/ARNTL) in the hypothalamus and liver were determined by immunohistochemical staining. The mRNA and protein levels of BMAL1, circadian locomotor output cycles kaput (CLOCK), period circadian clock 2 (PER2), and cryptochrome1 (Cry1) in the hypothalamus and liver were determined by Real-time PCR and Western blot, respectively. ResultsCompared with the blank group, the model group showed elevated levels of TG, TC, LDL-C, AST, and ALT (P<0.01) and a lowered level of HDL-C (P<0.05) in the serum, elevated levels of TG and NEFA in the liver (P<0.01), pyknosis and deep staining of hypothalamic neuron cells, and a large number of vacuoles in the brain area. In addition, the model group showed lipid deposition in the liver, up-regulated mRNA and protein levels of CLOCK and BMAL1 (P<0.01), and down-regulated mRNA and protein levels of Cry1 and PER2 (P<0.01) in the hypothalamus and liver. Compared with the model group, all the three modified Ditan tang groups showed lowered levels of TG, TC, LDL-C, ALT, and AST (P<0.05, P<0.01) and an elevated level of HDL-C (P<0.05) in the serum, and lowered levels of TG and NEFA (P<0.05, P<0.01) in the liver. Furthermore, the three groups showed alleviated pyknosis and deep staining of hypothalamic neuron cells, reduced lipid deposition in the liver, down-regulated mRNA and protein levels of CLOCK and BMAL1 (P<0.05, P<0.01), and up-regulated mRNA and protein levels of Cry1 and PER2 (P<0.05, P<0.01) in the hypothalamus and liver. ConclusionModified Ditan tang can reduce lipid deposition in the liver and regulate the expression of CLOCK, BMAL1, Cry1, and PER2 in the TTFL of NAFLD rats.

Objective To compare the long-term prognosis differences between surgical radical resection and endoscopic resection for early gastric cancer patients based on the SEER database. Methods A total of 1 437 patients with stage Tis to T1b gastric adenocarcinoma were selected from the SEER database from January 1, 2004 to December 31, 2013. They were divided into a surgery group (n=1 257) and an endoscope group (n=180) according to the treatment method. Kaplan-Meier survival curve and Cox regression model were used to analyze survival outcomes. Results The patients in the surgery group were younger than those in the endoscope group ([67.63±12.97] years old vs [71.29±10.82] years old), with higher rates of T1 stage (97.45% vs 87.78%) and lymph node metastasis (19.73% vs 5.00%, all P<0.001). The median follow-up time for all patients was 37 (15, 66) months, and the mortality rate of gastric cancer in the endoscope group was lower than that in the surgery group (23.33% vs 27.13%, P<0.001). Univariate Cox analysis showed that treatment modality, age, sex, T stage, lymph node metastasis were all associated with early gastric cancer mortality (all P<0.05), and the risk of death in the endoscope group was 43% of that in the surgery group (HR=0.43, P=0.015). After adjusting for multiple factors, there was no statistically significant difference in mortality risk between the two groups (P=0.067), but after excluding lymph node positive patients, the mortality risk in the endoscope group was 46% of that in the surgery group (HR=0.46, P=0.048). Conclusions For early gastric cancer patients with negative lymph nodes, endoscopic resection may provide better survival benefits than surgical procedures, suggesting that it can be the preferred treatment strategy for patients with low risk of lymph node metastasis.

Hearing loss is the most prevalent disabling disease. Cochlear implantation(CI) serves as the primary intervention for severe to profound hearing loss. This consensus systematically explores the value of genetic diagnosis in the pre-operative assessment and efficacy prognosis for CI. Drawing upon domestic and international research and clinical experience, it proposes an evidence-based medicine three-tiered prognostic classification system(Favorable, Marginal, Poor). The consensus focuses on common hereditary non-syndromic hearing loss(such as that caused by mutations in genes like GJB2, SLC26A4, OTOF, LOXHD1) and syndromic hereditary hearing loss(such as Jervell & Lange-Nielsen syndrome and Waardenburg syndrome), which are closely associated with congenital hearing loss, analyzing the impact of their pathological mechanisms on CI outcomes. The consensus provides recommendations based on multiple round of expert discussion and voting. It emphasizes that genetic diagnosis can optimize patient selection, predict prognosis, guide post-operative rehabilitation, offer stratified management strategies for patients with different genotypes, and advance the application of precision medicine in the field of CI.

Objective:To introduce a new design of super-micro flap for endoscopic ear surgery, and to evaluate the application effect of super-micro flap in endoscopic tympanoplasty. Methods:Between January, 2023 and March, 2024, 58 patients(64 ears) with tympanosclerosis underwent tympanoplasty with super-micro flap. Continuous irrigating mode endoscopic ear surgery(CIM-EES) was used to complete type Ⅱ or Ⅲ tympanoplasty with the tragus cartilage with followed up for 12 to 24 months. The operation time, postoperative efficacy and complications were statistically analyzed. Results:Of the 64 ears, 63 ears had primary healing of the tympanic membrane, and 1 ear had cartilage necrosis due to multi-drug resistant bacteria infection. The second operation was performed one year later, and the success rate of operation was 98.40%. The average operation time was (48.40±8.86) minutes. The average hearing threshold of 0.5 kHz to 4.0 kHz before operation was (59.63±10.62) dB HL, and the average air conduction threshold of 0.5 kHz to 4.0 kHz one year after operation was(38.79±10.91) dB HL, which was significantly improved compared with that before operation(P<0.01). Bone conduction threshold also improved significantly (24.49±8.55) dB HL vs(21.88±7.58) dB HL(P<0.01). No outer tympanic membrane healing and ear canal scar stenosis occurred. Conclusion:The design of super-micro flap can effectively solve the interference of flap floating during continuous irrigating mode in endoscopic ear surgery, relieve the difficulty of flap reposition, simplify the operation process, help to shorten the operation time, and reduce the possibility of circular scar stenosis of conventional free flap, which provides a new flap design option for endoscopic ear surgery.
