Based on the theory of "shaoyang（少阳） resembling the pivot" and collateral diseases， this article proposes that pulmonary fibrosis （PF） can be divided into three stages including wind bi （痹）， constraint bi， and atrophy bi. The core pathogenesis of PF is the obstruction of the pivot and pulmonary collateral obstruction. In terms of treatment， the basic principles are to harmonize and regulate the pivot， and to promote the circulation of the lung collaterals. Depending on the different characteristics of the "essence-attribute-function"， treatment methods such as harmonizing and regulating the pivot， resolving phlegm and removing stasis， supplementing deficiency and harmonizing collaterals are suggested. This approach ensures the regulation of the pivot， smooth circulation of qi and blood， unblocking of the lung collaterals and nourishing the lung body， achieving the goals of balancing the ascending and descending of qi， removing phlegm and stasis， and relieving cough and wheezing.

The core pathogenesis of attention deficit hyperactivity disorder （ADHD） lies in deficiency， stasis and stagnation. Deficiency arises from kidney essence depletion and spleen dysfunction in transportation and transformation， leading to inadequate nourishment of the marrow sea. Stasis caused by qi deficiency leads to obstruction in channels and collaterals， resulting in obstructed marrow transport. Stagnation is associated with the excess of the five minds transforming into fire， which scorches the brain orifices and leads to loss of control over marrow utilisation. Based on this， a "supplementation-unblocking-regulation" therapeutic approach is proposed. For deficiency， the focus is on supplementing kidney and fortifying spleen， and replenishing the marrow sea. For stasis， the priority is to unblock and open the orifices， and clear the marrow channels. For stagnation， the core is to clear fire and contain the mind， regulate and restore vital activity. In clinical practice， it is necessary to identify the primary and secondary pathogenic mechanisms and apply dynamic， combined treatment， integrating Chinese herbal medicine， acupuncture， and guiding exercises throughout the process， aiming to provide a reference for the diagnosis and treatment of ADHD with traditional Chinese medical.

Objective:To compare the diagnostic efficacy of 18F-fibroblast activation protein inhibitor (FAPI)-42 PET/CT and 18F-FDG PET/CT for bone metastasis in patients with malignant tumors. Methods:From January 2022 to October 2023, the data of 238 patients (160 males, 78 females; age: 58(50, 66) years) with various malignant tumors who underwent both 18F-FAPI-42 and 18F-FDG PET/CT imaging at Nanfang Hospital, Southern Medical University were retrospectively reviewed. An abnormal focal radioactive uptake in bones on the PET images was considered as positive lesion for bone metastasis. The efficacy of 2imaging methods and the supplementary role of CT in the diagnosis of bone metastasis were evaluated by McNemar test. Results:Of 238 patients, 95 were with bone metastases and 143 were without bone metastases, including 436 lesions with bone metastases and 358 lesions without bone metastases. Based on the visual analysis, 18F-FAPI-42 PET showed a higher diagnostic sensitivity than 18F-FDG PET (98.4%(429/436) vs 86.5%(377/436); χ2=41.95, P<0.001), while 18F-FDG PET had a higher diagnostic specificity than 18F-FAPI-42 PET (83.2%(298/358) vs 70.4%(252/358); χ2=22.50, P<0.001), and the accuracies of both methods were similar (85.8%(681/794) vs 85.0%(675/794); χ2=0.16, P=0.685). However, when the positive lesions seen in PET were analyzed combined with the image features on CT by the same scanner, the diagnostic specificity of 18F-FAPI-42 PET/CT was significantly improved compared to that of 18F-FAPI-42 PET alone (91.3%(327/358) vs 70.4%(252/358); χ2=73.01, P<0.001), and was similar to 18F-FDG PET/CT (93.0%(333/358); χ2=0.78, P=0.377). Meanwhile, this combined analysis brought a higher sensitivity and accuracy of 18F-FAPI-42 PET/CT than 18F-FDG PET/CT in diagnosing bone metastases (sensitivity: 98.4%(429/436) vs 86.5%(377/436); χ2=41.95, P<0.001; accuracy: 95.2%(756/794) vs 89.4%(710/794); χ2=21.54, P<0.001). Conclusions:The diagnostic sensitivity of 18F-FAPI-42 PET for bone metastasis is superior to 18F-FDG PET, but the specificity is lower. However, when CT features is combined for analysis, the diagnostic specificity of 18F-FAPI-42 PET/CT is significantly improved, which thus can be used to diagnose bone metastasis accurately and is superior to 18F-FDG PET/CT.

Objective To observe the effects of electroacupuncture at the Hegu(LI4)acupoint on refractive parame-ters and the expression of tumor necrosis factor-α(TNF-α)and interleukin-1 β(IL-1β)in the retinal tissue of mice with form-deprivation myopia(FDM).Methods Forty-eight SPF-grade,3-week-old healthy male C57BL/6J mice were ran-domly divided into four groups:normal control group,FDM group,sham acupuncture group,and Hegu group.Experimen-tal myopia was induced in the right eyes of mice in the latter three groups by wearing translucent diffuser goggles.Mice in the Hegu group received electroacupuncture stimulation at the Hegu(LI4)acupoint,while those in the sham acupuncture group received intervention with a non-penetrating blunt needle at the same location.Body weight,refractive error,and axial length were recorded for all mice before modeling and at 2 and 4 weeks after modeling.At 4 weeks post-modeling,mice were euthanized.Real-time quantitative PCR(RT-qPCR)and Western blot were used to detect the mRNA and protein expression levels of TNF-α and IL-1β,respectively,in the right retinal tissues.Retinal cell apoptosis was assessed by TUNEL staining.Results At 2 weeks post-modeling,compared with the normal control group,the refractive error of the right eyes was significantly decreased and the axial length was significantly increased in the FDM,sham acupuncture,and Hegu groups(all P＜0.01).At 4 weeks post-modeling,compared with the normal control group,the refractive error was significantly decreased and the axial length was significantly increased in the FDM and sham acupuncture groups(all P＜0.001).Compared with both the FDM and sham acupuncture groups,the Hegu group showed a significant increase in re-fractive error and a significant decrease in axial length(all P＜0.001).At 4 weeks post-modeling,RT-qPCR and Western blot results showed that the mRNA and protein expression levels of TNF-α and IL-1 β in the retina were significantly higher in the FDM and sham acupuncture groups compared to the normal control group(all P＜0.05).In contrast,the protein ex-pression level of TNF-α and the relative mRNA and protein expression levels of IL-1β in the Hegu group were significantly lower than those in the FDM group(all P＜0.05).TUNEL staining results showed that the retinal cell apoptosis rate was significantly higher in the FDM and sham acupuncture groups compared to the normal control group(all P＜0.001).Com-pared with the FDM and sham acupuncture groups,the retinal cell apoptosis rate was significantly lower in the Hegu group(all P＜0.001).Conclusion Electroacupuncture at the Hegu(LI4)acupoint can significantly inhibit the progression of myopia in mice.The mechanism may be related to the downregulation of TNF-α and IL-1β expression in the retinal tissue,thereby inhibiting retinal cell apoptosis.

γ-Aminobutyric acid(GABA),a pivotal inhibitory neurotransmitter in the central nervous system,plays an essential role in maintaining normal ocular physiological functions.GABA and its receptors are widely distributed through-out the retina,optic nerve,and visual pathways.Research indicates that GABA dysregulation is implicated in the pathogen-esis and progression of certain ophthalmic disorders.This article provides a comprehensive exploration of the relationship between GABA and ophthalmic diseases,including myopia,amblyopia,glaucoma,and dry eye syndrome.Moreover,the potential mechanisms and recent research advances are discussed.The findings may offer novel options and chances for the diagnosis and treatment of ophthalmic diseases.

Objective: To systematically evaluate the influencing factors for autism spectrum disorder (ASD) in Chinese children, so as to provide the evidence for risk prediction and intervention of ASD. Methods: The publications pertaining to the influencing factors for ASD in Chinese children were retrieved from CNKI, Wanfang Data, VIP, PubMed and Embase database from inception to August 2024. A meta-analysis was performed using R package version 4.4.1. Sensitivity analysis was performed using the "leave-one-out" evaluation procedure. Publication bias was assessed using Egger regression test. Results: A total of 38 high-quality articles out of 9 015 articles were finally included, covering 149 607 individuals, with 5 974 cases of ASD. The meta-analysis showed that demographic factors including family history of related diseases (OR=14.958), maternal age of ≥35 years (OR=2.287) and parental history of hazardous occupations (OR=3.511); pregnancy-related factors including history of abortion (OR=5.832), no folate supplementation before and during pregnancy (OR=4.566), tobacco exposure before and during pregnancy (OR=2.596), history of other adverse exposures before and during pregnancy (OR=3.533), history of infectious diseases during pregnancy (OR=3.753), history of non-infectious diseases during pregnancy (OR=2.563), psychological problems during pregnancy (OR=3.864), history of medication during pregnancy (OR=6.651), adverse environmental exposures during pregnancy (OR=3.754), severe pregnancy reactions (OR=5.082), abnormal perinatal period (OR=2.987), cesarean delivery (OR=1.659), other perinatal adverse factors (OR=3.856), history of neonatal asphyxia (OR=2.792) and neonatal jaundice (OR=3.687); parenting factors including non-exclusive breastfeeding (OR=2.510), early/excessive screen exposure (OR=3.589) and feeding problems (OR=3.113); and individual factors including being male (OR=3.333) and history of convulsions/epilepsy (OR=7.035) were influencing factors for ASD in Chinese children. Conclusions The prevalence of ASD in Chinese children is primarily associated with 23 influencing factors, including family history of related diseases, history of abortion, no folate supplementation before and during pregnancy, medication during pregnancy, early/excessive screen exposure and history of convulsions/epilepsy.

Objective In this study,we investigated the correlation between the scores for different Liebowitz Social Anxiety Scale(LSAS)subscale models and the metabolic activity in specific regions of the brain using 18F-fluorodeoxyglucose(FDG)positron emission tomography/computed tomography(PET/CT)(18F-FDG PET),thereby improving the understanding of the neurobiological characteristics of social anxiety.Methods A total of 39 cognitively normal participants(29 men and 10 women,aged 30-63 years)were enrolled.All participants underwent LSAS assessment and brain 18F-FDG PET scanning.Correlations between metabolic activities in various brain regions and scores from the different LSAS subscales were analyzed accordingly.Results LSAS subscale scores were significantly correlated with metabolic activity in specific brain regions.In the Safren model,the score for the observation by others subscale was positively correlated with the left fusiform gyrus(P<0.001,false discovery rate[FDR]-corrected)and the left caudate tail(P<0.001,FDR-corrected),suggesting a close association between mood states related to observation by others and the metabolic activity in these regions.In the Baker model,the score for the eating and drinking subscale was negatively correlated with the right precuneus(P<0.001,FDR-corrected),while the score for the assertiveness subscale was positively correlated with the left caudate nucleus(P<0.001,FDR-corrected).These findings revealed the complex associative patterns between various mood and behavioral dimensions and metabolic activities in specific brain regions.Conclusion Social anxiety symptoms are closely associated with metabolic changes in specific brain regions,including the left insula,left caudate tail,and right precuneus.Moreover,different social situations activate distinct brain regions.Compared with individuals with social anxiety disorder,normal individuals exhibit involvement of fewer brain regions when experiencing social anxiety.These findings provide new experimental evidence for understanding the neural mechanisms underlying social anxiety.
