Objective: To explore the association of physical activity and sugar sweetened beverage consumption with psychological sub health among middle school students in Bao an District, Shenzhen, so as to provide a reference for adolescent mental health promotion. Methods: A questionnaire survey was conducted in November 2024 by a stratified cluster random sampling method to select 6 926 junior and senior middle school students from 5 middle schools in Shenzhen. The questionnaire from Youth Risk Behavior Surveillance System was used to assess the consumption of sugar sweetened beverages, and physical activity Rating Scale was used to assess the level of physical activity, and Brief Instrument on Psychological Health of Youths was used to evaluate the psychological sub health status. The Chi -square test was used to analyze the differences in the detection rates of psychological sub health among different groups of middle school students, and a multivariate Logistic regression model was established to analyze the effects of physical activity and sugar sweetened beverage consumption and their combined effects on the psychological sub health of middle school students. Results: The detection rate of psychological sub health among middle school students in Bao an District, Shenzhen was 18.93%. Multivariate Logistic regression analysis showed that, after controlling for confounding factors such as gender, school stage, family residence, family economic status, parental literacy, academic stress and number of friends, lack of physical activity or excessive sugar sweetened beverage consumption were associated with increased risks of psychological sub health among middle school students ( OR =1.36, 1.45); and the highest risk of psychological sub health was found in middle school students who were lack of physical activity and excessive sugar sweetened beverage consumption ( OR =2.59) ( P <0.01). Further analysis by school stages showed that junior high school students with sufficient physical activity and excessive intake of sugary drinks ( ROR =2.10), lack of physical activity and excessive intake of sugary drinks ( ROR =2.31) were at higher risks of psychological sub health than senior high school students( P <0.05). Conclusions Insufficient physical activity and excessive sugar sweetened beverage consumption are closely associated with an increased risk of psychological sub health among middle school students. Effective interventions should be targeted to reduce the risk of psychological sub health problems among middle school students.

This study employed the "disease-medicine-dose" pattern to mine the medication rules of traditional Chinese medicine(TCM) prescriptions containing Astragali Radix in ancient Chinese medical books, aiming to provide a scientific basis for the clinical application of Astragali Radix and the development of new medicines. The TCM prescriptions containing Astragali Radix were retrieved from databases such as Chinese Medical Dictionary and imported into Excel 2020 to construct the prescription library. Statical analysis were performed for the prescriptions regarding the indications, syndromes, medicine use frequency, herb effects, nature and taste, meridian tropism, dosage forms, and dose. SPSS statistics 26.0 and IBM SPSS Modeler 18.0 were used for association rules analysis and cluster analysis. A total of 2 297 prescriptions containing Astragali Radix were collected, involving 233 indications, among which sore and ulcer, consumptive disease, sweating disorder, and apoplexy had high frequency(>25), and their syndromes were mainly Qi and blood deficiency, Qi and blood deficiency, Yin and Yang deficiency, and Qi deficiency and collateral obstruction, respectively. In the prescriptions, 98 medicines were used with the frequency >25 and they mainly included Qi-tonifying medicines and blood-tonifying medicines. Glycyrrhizae Radix et Rhizoma, Angelicae Sinensis Radix, Ginseng Radix et Rhizoma, Atractylodis Macrocephalae Rhizoma, and Citri Reticulatae Pericarpium were frequently used. The medicines with high frequency mainly have warm or cold nature, and sweet, pungent, or bitter taste, with tropism to spleen, lung, heart, liver, and kidney meridians. In the treatment of sore and ulcer, Astragali Radix was mainly used with the dose of 3.73 g and combined with Glycyrrhizae Radix et Rhizoma to promote granulation and heal up sores. In the treatment of consumptive disease, Astragali Radix was mainly used with the dose of 37.30 g and combined with Ginseng Radix et Rhizoma to tonify deficiency and replenish Qi. In the treatment of sweating disorder, Astragali Radix was mainly used with the dose of 3.73 g and combined with Glycyrrhizae Radix et Rhizoma to consolidate exterior and stop sweating. In the treatment of apoplexy, Astragali Radix was mainly used with the dose of 7.46 g and combined with Glycyrrhizae Radix et Rhizoma to dispell wind and stop convulsions. Astragali Radix can be used in the treatment of multiple system diseases, with the effects of tonifying Qi and ascending Yang, consolidating exterior and stopping sweating, and expressing toxin and promoting granulation. According to the manifestations of different diseases, when combined with other medicines, Astragali Radix was endowed with the effects of promoting granulation and healing up sores, tonifying deficiency and Qi, consolidating exterior and stopping sweating, and dispelling wind and replenishing Qi. The findings provide a theoretical reference and a scientific basis for the clinical application of Astragali Radix and the development of new medicines.

Patients suffering from nerve injury often experience exacerbated pain responses and complain of memory deficits. The dorsal hippocampus (dHPC), a well-defined region responsible for learning and memory, displays maladaptive plasticity upon injury, which is assumed to underlie pain hypersensitivity and cognitive deficits. However, much attention has thus far been paid to intracellular mechanisms of plasticity rather than extracellular alterations that might trigger and facilitate intracellular changes. Emerging evidence has shown that nerve injury alters the microarchitecture of the extracellular matrix (ECM) and decreases ECM rigidity in the dHPC. Despite this, it remains elusive which element of the ECM in the dHPC is affected and how it contributes to neuropathic pain and comorbid cognitive deficits. Laminin, a key element of the ECM, consists of α-, β-, and γ-chains and has been implicated in several pathophysiological processes. Here, we showed that peripheral nerve injury downregulates laminin β1 (LAMB1) in the dHPC. Silencing of hippocampal LAMB1 exacerbates pain sensitivity and induces cognitive dysfunction. Further mechanistic analysis revealed that loss of hippocampal LAMB1 causes dysregulated Src/NR2A signaling cascades via interaction with integrin β1, leading to decreased Ca²⁺ levels in pyramidal neurons, which in turn orchestrates structural and functional plasticity and eventually results in exaggerated pain responses and cognitive deficits. In this study, we shed new light on the functional capability of hippocampal ECM LAMB1 in the modulation of neuropathic pain and comorbid cognitive deficits, and reveal a mechanism that conveys extracellular alterations to intracellular plasticity. Moreover, we identified hippocampal LAMB1/integrin β1 signaling as a potential therapeutic target for the treatment of neuropathic pain and related memory loss.

OBJECTIVE: Observational studies have shown inconsistent associations of loneliness or social isolation (SI) with ischemic heart disease (IHD), with unknown mediators. METHODS: Using data from genome-wide association studies of predominantly European ancestry, we performed a bidirectional two-sample Mendelian Randomization (MR) study to estimate causal effects of loneliness ( N = 487,647) and SI traits on IHD ( N = 184,305). SI traits included whether individuals lived alone, participated in various types of social activities, and how often they had contact with friends or family ( N = 459,830 to 461,369). A network MR study was conducted to evaluate the mediating roles of 20 candidate mediators, including metabolic, behavioral and psychological factors. RESULTS: Loneliness increased IHD risk ( OR= 2.129; 95% confidence interval [ CI]: 1.380 to 3.285), mediated by body fat percentage, waist-hip ratio, total cholesterol, and low-density lipoprotein cholesterol. For SI traits, only fewer social activities increased IHD risk ( OR= 1.815; 95% CI: 1.189 to 2.772), mediated by hypertension, high-density lipoprotein cholesterol, triglycerides, fasting insulin, and smoking cessation. No reverse causality of IHD with loneliness and SI was found. CONCLUSION These findings suggested more attention should be paid to individuals who feel lonely and have fewer social activities to prevent IHD, with several mediators as prioritized targets for intervention.

Objective To analyze the accuracy of the new generation intraocular lens(IOL)formula and the Wang-Koch(WK)adjustment in individuals with severe myopia undergoing combined anterior-posterior surgery.Methods A total of 100 patients(100 eyes)with axial length(AL)＞26 mm undergoing combined anterior and posterior segment surgery in our department from June 2015 to June 2021 were enrolled in this study.Totally 13 IOL calculation formulas,such as Barrett Universal Ⅱ(BU Ⅱ),Emmetropia Verifying Optical(EVO),Kane,Haigis,Hoffer Q,Holladay,and SRK/T as well as the first generation linear WK eye axis optimization formula(Haigis-WK1,SRK/T-WK1,Hoffer Q-WK1,Holladay 1-WK1)and the second generation linear WK eye axis optimization formula(SRK/T-WK2,Holladay 1-WK2),were utilized to determine IOL diopter.The mean prediction error(ME),mean absolute error(MAE),median absolute error(MedAE),and percentage of prediction error within different refractive thresholds were calculated to assess the accuracy of each formula.In order to investigate the impact of AL on accuracy of IOL calculation,the patients were categorized into group A(38 eyes,26.00 mm＜AL≤28.00 mm),group B(28 eyes,28.00 mm＜AL≤30.00 mm),and group C(34 eyes,AL＞30.00 mm).Additionally,the patients were also divided into silicone oil(63 eyes)and non-silicone oil(37 eyes)groups based on preoperative intraocular filling to determine the effect of intraocular filling on IOL calculation.Results The MedAE values of the new-generation IOL formulas(BU Ⅱ,EVO,and Kane)were significantly lower(0.34D,0.31D,0.35D)than those of traditional formulas(P＜0.05).Additionally,the percentage of prediction errors within±0.25 D,±0.50 D,±0.75 D,and±1.00 D were significantly higher with the new formulas when compared to traditional ones(P＜0.05).Traditional formulas exhibited a hyperopic deviation(0.35D～0.65 D),which could be corrected using the WK eye axis adjustment.WK2 was effective in improving the accuracy of calculation in SRK/T and Holladay 1 formulas,and there was no statistical difference in the MedAE values of SRK/T-WK2 and Holladay 1-WK2 formulas with the new-generation IOL formulas.When comparing the formulas across different axial eye length groups in terms of MedAE,the new IOL formulas(BU Ⅱ,kane and EVO)and WK-corrected formulas(Haigis-WK1,SRK/T-WK 1,SRK/T-WK2,Hoffer Q-WK1,Holladay 1-WK1,Holladay 1-WK2)showed no significant differences among the different AL groups.However,there were significant differences in the MedAE values of traditional formulas among the different AL groups(P＜0.01),with group C displaying the largest MedAE values(Haigis:0.84D,SRK/T:1.10D,Hoffer Q:1.23D,Holladay 1:1.20D).Comparing the MedAE values of different formulas in various preoperative intraocular filling groups,it was observed that the MedAE values of the new-generation IOL formulas(BU Ⅱ,kane and EVO),Haigis,and SRK/T formulas were significantly higher in the silicone oil-filled eye group than the non-silicone oil-filled eye group(P＜0.05).Conclusion In patients with high myopia undergoing combined anterior and posterior segment surgery,the precision and consistency of the new-generation IOL formulas and the second-generation linear WK axis correction formula exhibit significant improvements when compared to traditional formulas.

Purpose To investigate the ultrasound features and classification of pilomatricoma and its correlation with pathological manifestations.Materials and Methods The clinical,ultrasound and pathological data of 76 patients(78 lesions)postoperative confirmed pilomatricoma in Henan Province Hospital of Traditional Chinese Medicine and the the First Affiliated Hospital of Henan University of Traditional Chinese Medicine from July 2014 to August 2021 were analyzed,retrospectively.According to the presence or absence of calcification and the pattern of calcification in the sonogram,they were divided into no calcification type,dotted calcification type,sheet calcification type and complete calcification type.Results Pilomatricoma were most common in children under 10,with predilection location in the face and head.Most lesions were surrounded by hypoechoic halo and calcification,51 of 78 lesions had different degrees of calcification,accounting for about 65.4%;36 lesions were with hypoechoic halo;63 lesions were mainly hypoechoic,accounting for about 80.8%.There were statistical differences in hypoechoic halo(χ2=15.624,P=0.001)and internal echo(χ2=12.801,P=0.021)among different classification pilomatricoma.Shadow cells and basicyte were detected in all 78 lesions,basophil cells were found in the periphery of 50 out of 54 lesions showing hypoechoic halos.The ultrasound manifestations of different types had characteristic changes corresponding to their pathological composition.Conclusion The ultrasound performance varies among the different types of pilomatricoma,and there is a correlation with its pathological changes.Familiarization with the sonographic presentation of pilomatricoma in the different types contributes to the preoperative diagnosis.

Objective To investigate the incidence rate,clinical characteristics,and prognosis of neonatal stroke in Shenzhen,China.Methods Led by Shenzhen Children's Hospital,the Shenzhen Neonatal Data Collaboration Network organized 21 institutions to collect 36 cases of neonatal stroke from January 2020 to December 2022.The incidence,clinical characteristics,treatment,and prognosis of neonatal stroke in Shenzhen were analyzed.Results The incidence rate of neonatal stroke in 21 hospitals from 2020 to 2022 was 1/15 137,1/6 060,and 1/7 704,respectively.Ischemic stroke accounted for 75％(27/36);boys accounted for 64％(23/36).Among the 36 neonates,31(86％)had disease onset within 3 days after birth,and 19(53％)had convulsion as the initial presentation.Cerebral MRI showed that 22 neonates(61％)had left cerebral infarction and 13(36％)had basal ganglia infarction.Magnetic resonance angiography was performed for 12 neonates,among whom 9(75％)had involvement of the middle cerebral artery.Electroencephalography was performed for 29 neonates,with sharp waves in 21 neonates(72％)and seizures in 10 neonates(34％).Symptomatic/supportive treatment varied across different hospitals.Neonatal Behavioral Neurological Assessment was performed for 12 neonates(33％,12/36),with a mean score of(32±4)points.The prognosis of 27 neonates was followed up to around 12 months of age,with 44％(12/27)of the neonates having a good prognosis.Conclusions Ischemic stroke is the main type of neonatal stroke,often with convulsions as the initial presentation,involvement of the middle cerebral artery,sharp waves on electroencephalography,and a relatively low neurodevelopment score.Symptomatic/supportive treatment is the main treatment method,and some neonates tend to have a poor prognosis.

Objective: To explore the mechanism by which icariin alleviates viral myocarditis. Methods: CVB3-induced cardiomyocytes were used as an in vitro model of viral myocarditis to assess the effects of icariin treatment on cell viability, inflammation, and apoptosis. Moreover, the effects of icariin on ferroptosis and TLR4 signaling were assessed. After AC16 cells were transfected with TLR4 overexpression plasmids, the role of TLR4 in mediating the regulatory effect of icariin in viral myocarditis was investigated. Results: Icariin significantly elevated cell viability and reduced inflammatory factors TNF-α, IL-1β, IL-6, and IL-18. Flow cytometry revealed that icariin decreased apoptosis rate, and the protein expression of Bax and cleaved caspase 3 and 9 in CVB3-induced cardiomyocytes. Additionally, it suppressed ferroptosis including lipid peroxidation and ferrous ion, as well as the TLR4 signaling. However, TLR4 overexpression abrogated the modulatory effects of icariin. Conclusions: Icariin mitigates CVB3-induced myocardial injury by inhibiting TLR4-mediated ferroptosis. Further animal study is needed to verify its efficacy.

Objective To evaluate the efficacy of Broncho-Vaxom combined with physiological sea water nasal wash in the treatment of chronic rhinitis-rhinosinusitis in children. Methods A total of 179 children with chronic rhinitis-rhinosinusitis were randomly divided into observation group of 90 cases and control group of 89 cases. The observation group received treatment of oral administration of Broncho-Vaxom capsules at a dose of 3.5 mg once daily on an empty stomach in the morning for 10 consecutive days, with a 20-day drug-free period as one course of treatment, for a total of 3 courses. Additionally, they underwent nasal irrigation with physiological sea water twice daily in the morning and evening, for 10 consecutive days, with a 20-day break as one course of treatment, for a total of 3 courses. The control group underwent nasal irrigation with physiological sea water using the same method of the observation group. Both groups received symptomatic treatment such as anti-allergy therapy, and antibiotics were added when there presented obvious inflammatory changes. After treatment, the clinical total effective rate was compared between the two groups. Changes in the scores of Visual Analogue Scale (VAS) and Lund-Kenndy scale for nasal endoscopy, as well as changes in serum IgG, IgE, and T lymphocyte subsets were also compared. A six-month follow-up was conducted to assess the recurrence rate and average number of episodes of rhinosinusitis (times per person). Results The clinical total effective rate in the observation group was significantly higher compared to that in the control group(95.56% versus 86.52%). The scores of VAS and Lund-Kenndy scale in the observation group were significantly better than those in the control group. Serum IgG levels in the observation group were increased and higher than those in the control group, while serum IgE level in the observation group was decreased and lower than that in the control group. After 3 courses of treatment, the levels of CD3⁺, CD4⁺, and CD4⁺/CD8⁺ in the blood of the observation group were increased, while the level of CD8⁺ was decreased. The six-month follow-up after treatment showed that the recurrence rate of rhinitis-rhinosinusitis in the observation group was 17.05%, with an average of 0.28 episodes per person, which was lower than that in the control group (P < 0.05). Conclusion The combination of Broncho-Vaxom and physiological sea water nasal wash is effective in treating chronic rhinitis-rhinosinusitis in children, and can increase serum IgG level, decrease serum IgE level, optimize the structure of T lymphocyte subsets, enhance immune resistance, and improve allergic constitution. The six-month follow-up of the treatment reduces recurrence rate and average number of episodes of rhinitis-rhinosinusitis.

"Solid-liquid excipients" co-production is one of the typical processing methods of excipients used from ancient times to the present day, and is widely applied in various processing schools and regional specialty varieties. This method significantly reduces the toxicity of traditional Chinese medicine(TCM), moderates medicinal properties, and enhances clinical efficacy. However, modern scientific research has given it limited attention, and many co-production methods of "solid-liquid excipients" have not been applied in production and practice. This paper reviewed the historical development of "solid-liquid excipients" co-production, outlined modern processing standards and methods in different processing schools, and further elaborated on the purposes and effects of this co-production method. This study is expected to provide references and evidence for further in-depth research, inheritance, innovation, and practical application.
