Chinese Journal of School Health 2025;46(1):18-23
Objective:
To analyze the status of outdoor activities on weekends among children and adolescents of different educational stages in Shanghai and their impact on myopia, so as to provide a basis for formulating more specific prevention and control protocol of myopia.
Methods:
From September to October 2022, a stratified cluster random sampling method was employed to select 84 schools (27 kindergartens, 21 primary schools, 15 junior high schools and 21 high schools) across Shanghai, enrolling a total of 28 654 children and adolescents aged 4 to 18 for the study. Ophthalmic examinations were conducted to ascertain the prevalence of myopia among children and adolescents. Additionally, a questionnaire survey was administered to collect data on outdoor activity duration and associated factors. Multivariate Logistic regression analysis was utilized to investigate the associated factors of outdoor activity levels on weekends.
Results:
The overall myopia detection rate among children and adolescents was 58.4%, with a higher rate observed in girls (59.2%) compared to boys (57.6%). The myopia detection rates for children and adolescents with an average daily outdoor activity duration of ≥2 h and <2 h on weekends were 54.6% and 68.8%, and the differences were statistically significant ( χ 2=8.12,460.89, P <0.01). Multivariable Logistic regression analysis revealed that girls ( OR =0.80), those with a myopic parent ( OR =0.68), schools from urban districts ( OR =0.72), higher education stages (primary school: OR =0.65, junior high school: OR =0.24, high school: OR =0.14) and spending≥2 h/d on homework during weekends ( OR =0.57) among children and adolescents were less likely to engage in outdoor activities for ≥2 h on weekends ( P <0.01). After incorporating gender, parental myopia status, educational stage, school location, average daily duration on weekends for spending on homework, electronic product usage and outdoor activities as dependent variables in a multivariate Logistic regression analysis, the results showed that children and adolescents with an average outdoor activity duration for ≥2 h on weekends had a lower risk of myopia ( OR =0.86, P < 0.01).
Conclusions
The level of outdoor activity among children and adolescents on weekends needs to be improved. Outdoor activities on weekends is an associated factor for myopia among children and adolescents. Particularly, girls, those with myopic parents, schools from urban districts, and spending long hours on homework during weekends among children and adolescents require increased attention.

Systemic lupus erythematosus (SLE), a refractory autoimmune disease, is among the dominant diseases where traditional Chinese medicine (TCM) shows advantages in the field of rheumatology and immunology. The China-Japan Friendship Hospital hosted the "46th Youth Salon on Dominant Diseases (Systemic Lupus Erythematosus)" organized by the China Association of Chinese Medicine, which led to a consensus on "the advantages, challenges, interdisciplinary approaches, and translational achievements of integrated TCM and Western medical approaches in the diagnosis and treatment of SLE." The diagnosis and treatment of SLE currently face several challenges, such as frequent misdiagnosis and missed diagnosis in the early stages, difficulty in achieving treatment targets, multiple side effects from pharmacotherapy, and the lack of management strategies for special populations, all of which hinder the fulfillment of the clinical needs of patients. Integrated TCM and Western medical approaches can improve clinical symptoms such as skin erythema, aversion to cold and cold limbs, fatigue, dry mouth, restlessness, and heat sensation in the palms and soles, thereby improving patients' quality of life. The approaches also help consolidate the efficacy of conventional Western medicine, slow disease progression, reduce relapse rates, address multi-organ involvement, and prevent or treat complications. Additionally, they enhance efficacy and reduce toxicity, prevent the side effects of Western medications, help reduce hormone use, and offer distinct advantages in the individualized intervention of special populations, contributing to the whole-process management of the disease. However, evidence-based medical support for this integrated approach remains limited, and the quality of available evidence is generally low. Common evaluation systems and modern research methodologies should be adopted to clarify the efficacy of TCM in SLE treatment. Efforts should be made to carry out high-quality evidence-based medical research, strengthen the development of fundamental and pharmacological research, and further explain the distinct advantages of TCM in the diagnosis and treatment of SLE. Future efforts should focus on advancing the integration of TCM and modern medicine, incorporating multi-omics technologies, individualized stratification, and other precision medicine concepts, in combination with artificial intelligence. Moreover, interdisciplinary collaboration should be promoted to utilize modern technology in exploring the essence of TCM theories and screening effective formulae, thereby comprehensively improving the diagnosis and treatment of SLE through integrated TCM and Western medical approaches.

Journal of Traditional Chinese Medical Sciences 2024;11(3):340-350
Objective:
To determine the main components of Astragalus membranaceus (Fisch.) Bge (A. membranaceus, Huang Qi), Astragaloside IV (AIV) and Astragalus polysaccharides (AP), to characterize their properties, evaluate their in vivo efficacy, and to analyze drug diffusion using dissolving microneedle (DMN) technology in vivo.
Methods:
Respectively, AIV- and AP-loaded DMNs comprising chitosan (CTS) and polyvinyl alcohol (PVA) were prepared via dual-mold forming. Their morphology, mechanical properties, in vivo solubility, and skin irritation characteristics were tested. In vivo efficacy was assessed in cyclophosphamide-induced immunosuppressed mice, in vivo diffusion of AIV and AP by DMNs and conventional methods was compared, and the rheological properties of AIV-CTS-PVA and AP-CTS-PVA mixtures were measured.
Results:
Subcutaneous dissolution and absorption of AIV-CTS-PVA and AP-CTS-PVA microneedles (MNs) at low doses (50%–17% of intraperitoneal AIV injection and 12%–4% of intravenous AP injection) reduced the spleen index and acid phosphatase activity in immunosuppressed mouse models, increased the thymus index, and achieved equivalent or better systemic therapeutic effects. Compared with injections, AIV and AP achieved controllable solid-liquid conversion through delivery with CTS-PVA MNs, resulting in highly localized aggregation within 48 h, reducing the initial explosive effect of the drug, and achieving stable and slow drug release.
Conclusion
The present study enhances our understanding of the efficacy and remote effects of drug-loaded DMNs from a traditional Chinese medicine (TCM) perspective, thereby promoting the development of precise and efficient delivery of TCM and further expanding the drug-loading range and application scenarios for DMNs.

ObjectiveTo observe the effect of Shufeng Jiedu capsule (SFJD)-containing serum on human lung epithelial cells infected by influenza A virus, and investigate the protective effect of the drug on the cells and the potential antiviral effect. MethodThe SFJD-containing serum was prepared and used to treat human lung epithelial cells (BEAS-2B) cultured in vitro. The viability of cells treated with different concentrations of SFJD-containing serum was measured by the cell counting kit-8 (CCK-8), and the optimal concentration of SFJD-containing serum was screened for subsequent experiments. BEAS-2B cells were classified into normal control, virus infection, and SFJD-containing serum groups, and the CCK-8 method was used to detect the survival rate of BEAS-2B cells after virus infection and drug administration. The expression of influenza virus nucleic acid in the cells of each group was determined, and the apoptosis of cells in different groups was observed by fluorescence microscopy. Real-time PCR was employed to determine the mRNA levels of influenza virus nucleoprotein (NP), Toll-like receptor 4 (TLR4), and myeloid differentiation primary response gene 88 (MyD88) in each group of cells. The immunofluorescence assay was used to detect the fluorescence intensities of TLR4, MyD88, and phosphorylated nuclear factor-κB (p-NF-κB) in lung epithelial cells. ResultCompared with that in the control group (normal serum), the cell survival rates in the blank serum and the SFJD-containing serum (5%, 10%, and 20%) groups were 100.00%±0.00%, 89.05%±4.80%, 87.13%±5.90%, 93.83%±6.03%, and 99.33%±3.39%, respectively (P<0.01). The SFJD-containing serum of 20% was selected as the optimal treatment for subsequent experiments. Compared with the normal control group, the virus infection group showed reduced cell survival rate (P<0.01), and the reduction was increased by the SFJD-containing serum (P<0.01). Compared with the virus infection group, SFJD-containing serum reduced the virus load (P<0.01) to decrease apoptosis. Compared with the normal control group, the virus infection group showed up-regulated mRNA levels of NP, TLR4, and MyD88 (P<0.01), and the up-regulation was down-regulated by the SFJD-containing serum (P<0.05, P<0.01). The fluorescence intensities of TLR4, MyD88, and p-NF-κB proteins in the cells increased after virus infection compared with those in the normal control (P<0.05, P<0.01), and they were decreased after administration with the SFJD-containing serum (P<0.05). ConclusionThe SFJD-containing serum can inhibit influenza virus in vitro by increasing the survival rate, reducing the apoptosis, and down-regulating the protein levels of TLR4, MyD88, and p-NF-κB in BEAS-2B cells.

Cinnamomi Ramulus and Alismatis Rhizoma are commonly used in the treatment of external-contraction diseases. Cinnamomi Ramulus is pungent, sweet, and warm, with the effects of ventilating lung and dispersing cold, warming Yang and transforming Qi, and promoting water and liquid flow from Taiyang meridian to remove dampness. Alismatis Rhizoma is sweet and cold, with the effects of draining dampness and promoting urination, regulating the waterway, removing water retention in lung, and promoting urination to remove dampness and heat. Herbal pairs are extracted from the accumulated experience of medical practitioners over the ages in the use of medicines and have been proved by clinical application to be composed of simple and effective combinations for specific diseases. The herb pair Cinnamomi Ramulus-Alismatis Rhizoma is an important part in ancient classic formulas such as Wulingsan. Both herbs play a role in draining dampness and promoting urination, warming Yang and transforming Qi, being a representative herb pair used for treating external-contraction exterior syndrome and water retention inside. The review of ancient medical publications revealed that there were a large number of compound formulas containing Cinnamomi Ramulus-Alismatis Rhizoma for dispersing cold and removing dampness, which were widely used for thousands of years in clinical practice. Modern pharmacological studies have shown that the active pharmacological components of Cinnamomi Ramulus (cinnamaldehyde and cinnamic acid) and Alismatis Rhizoma (alisol A and 23-acetate alisol B) have anti-inflammatory, antiviral, and immunoregulatory effects and high safety. Qingfei Paidu decoction containing this herbal pair played an important role in fighting against COVID-19. Despite the extensive pharmacological studies on Cinnamomi Ramulus and Alismatis Rhizoma, few studies have been carried out regarding this herb pair. This paper summarizes the traditional Chinese medicine knowledge about Cinnamomi Ramulus and Alismatis Rhizoma in the treatment of external-contraction diseases and summarizes the chemical composition, pharmacological effects, toxicology and other aspects of the two herbs before and after compatibility, aiming to provide a reference for further research and clinical application.

ObjectiveTo investigate the possible mechanism of Hewei Anshen Formula (和胃安神方) in the treatment of insomnia. MethodsSixty male SD rats were randomly divided into the normal group, the model group, the eszopiclone group and the low-, medium- and high-dose Hewei Anshen Formula groups. The insomnia model was constructed by intraperitoneal injection of p-chlorophenylalanine (PCPA) for 2 days in all groups except the normal group. After successful modelling, the eszopiclone group was given 0.33 mg/(kg·d) eszopiclone aqueous solution by gavage, the low-, medium- and high-dose Hewei Anshen Formula groups were given 10 ml/kg of Hewei Anshen Formula with a concentration of 1, 2 and 4 g/ml, respectively, and the rats in the normal group and the model group were given 10 ml/kg of saline by gavage, once a day for 7 consecutive days. The general condition of the rats was observed during the experiment, and the body mass of the rats was measured every day after medication administration. The following day after the last medication administration, pentobarbital sodium co-test was used to observe the sleep condition, and the sleep latency and sleep duration were recorded; immunohistochemistry and Western blot were used to detect the expression of hypothalamic clock rhythm regulating protein (CLOCK) and brain and muscle aromatic hydrocarbon receptor nuclear transporter-like protein 1 (BMAL1) in the rats. ResultsThe body mass of rats in the model group was lower than that of rats in the normal group at all time points (P<0.01); compared with the same time in the eszopiclone group, the body mass of rats in the low-dose Hewei Anshen Formula group was elevated on the 5th, 6th and 7th days of medication administration (P<0.05). Compared with the normal group, the sleep duration of rats in the model group was shortened (P<0.01); compared with the model group, the sleep duration of rats in each dosage group increased (P<0.01), and the difference between the high-dose Hewei Anshen Formula group and the eszopiclone group showed no statistically significant (P>0.05), while the sleep duration of the low- and medium-dose Hewei Anshen Formula groups were shorterned than the eszopiclone group (P<0.01). The difference in sleep latency showed no statistically significant among each group (P>0.05). The results of both immunohistochemistry and Western blotting showed that the expression of CLOCK and BMAL1 in the hypothalamus of rats in the model group was significantly reduced compared with that in the normal group (P<0.01); the expression of CLOCK and BMAL1 in the hypothalamus of rats in the low- and high-dose Hewei Anshen Formula groups increased than that in the model group (P<0.05 or P<0.01). ConclusionHewei Anshen Formula can improve insomnia in model rats, and its mechanism of action may be related to the up-regulation of the expression of the hypothalamic biological clock genes CLOCK and BMAL1 protein.
