The antidepressant activity and molecular mechanisms of Yueju Wan volatile oil were investigated. The Yueju Wan volatile oil was extracted by using supercritical CO_2. Gas chromatography-mass spectrometry(GC-MS) combined with network pharmacology identified 28 chemical constituents in Yueju Wan volatile oil, primarily terpenes and lactones. A total of 123 overlapping targets were associated with depression, including core targets of interleukin-1β(IL-1β), signal transducer and activator of transcription 3(STAT3), and caspase-3(CASP3). These targets were mainly involved in the prolactin, advanced glycation end products/receptor(AGE/RAGE), and phosphoinositide 3-kinase/protein kinase B(PI3K/Akt) signaling pathways. A reserpine-induced depression mouse model was established to evaluate the therapeutic effects and mechanisms of Yueju Wan volatile oil. The effects of Yueju Wan volatile oil on depression-like behavior in mice were evaluated by analyzing body mass, body temperature index, tail suspension immobility time, forced swimming immobility time, and sucrose preference. Hematoxylin-eosin(HE) staining revealed neuronal protection of Yueju Wan volatile oil in the brain of mice. Enzyme-linked immunosorbent assay(ELISA) and Western blot were employed to detect the protein expression of AGEs, IL-1β, phosphorylated PI3K(p-PI3K), Akt, phosphorylated Akt(p-Akt), nuclear factor κB(NF-κB), and brain-derived neurotrophic factor(BDNF). Behavioral evaluation showed that Yueju Wan volatile oil could effectively control the decline of body mass and body temperature of depressed mice, reduce tail suspension and swimming immobility time, and enhance their preference for sucrose. Histopathological examination showed that Yueju Wan volatile oil could alleviate the neuronal damage in CA1 and dentate gyrus(DG) of the hippocampus of mice. ELISA and Western blot results showed that Yueju Wan volatile oil could significantly increase the protein expression levels of PI3K, Akt, and BDNF and significantly decrease the protein expression levels of AGEs, IL-1β, p-PI3K, p-Akt, and NF-κB in the hippocampus of mice. Furthermore, the p-PI3K/PI3K and p-Akt/Akt ratios were significantly decreased at medium and high doses. These findings suggest that the aromatherapy of Yueju Wan volatile oil can significantly improve reserpine-induced depression-like behavior in mice, which may be related to reducing the expression of neuronal membrane protein AGEs, reducing the phosphorylation levels of PI3K and Akt, inhibiting NF-κB entry into the nucleus, and alleviating the release of pro-inflammatory factors and nerve injury.

Through a comprehensive analysis combining network pharmacology prediction and transcriptomics, this study systematically explained the multi-target mechanism of Cyanotis arachnoidea(CA) Gel in improving melasma. A melasma model was induced in female SD rats by progesterone injection combined with ultraviolet B(UVB) irradiation for 40 consecutive days, while the blank control group was only fed routinely. After successful model establishment, the rats were randomly divided into five groups and administered different doses of CA ethanol extract gel(high, medium, and low doses) or arbutin Gel(positive control), which were applied once daily for 28 consecutive days. Subsequently, the levels of superoxide dismutase(SOD), malondialdehyde(MDA), and tyrosinase(TYR) in the skin, serum, and liver tissues were measured. Hematoxylin-eosin(HE) staining and Masson-Fontana staining were used to observe the pathological changes in the tissues. Network pharmacology combined with transcriptomics was employed to identify core targets and pathways, and the differential gene expression was validated by quantitative real-time PCR(qPCR). Pharmacodynamic experiments showed that CA Gel significantly increased SOD activity and decreased MDA and TYR levels in the skin, serum, and liver of model rats. It also improved epidermal thickening, inflammatory infiltration, collagen loss, and melanin deposition. Network pharmacology analysis showed that CA mainly regulated core targets such as signal transducer and activator of transcription 3(STAT3), epidermal growth factor receptor(EGFR), and interleukin-6(IL-6), and modulated the phosphatidylinositol 3-kinase(PI3K)-protein kinase B(AKT) and interleukin-17(IL-17) signaling pathways. Transcriptomic analysis showed that CA Gel significantly downregulated the gene expression of heat shock protein 90β family member 1(Hsp90b1), heat shock protein 90α family member 1(Hsp90aa1), and the key steroid synthesis enzyme cytochrome P450 family 17 subfamily A member 1(Cyp17a1), while upregulating thioredoxin 1(Txn1). qPCR results confirmed that CA Gel regulated oxidative stress and inflammatory response by inhibiting the IL-17 signaling pathway and steroid hormone synthesis. This study, for the first time, reveals the molecular mechanism of CA Gel in improving melasma through multi-target synergistic regulation of oxidative stress, inflammatory response, and hormone metabolism pathways, providing a scientific basis for the treatment of pigmentation diseases with traditional Chinese medicine.

Early screening, diagnosis, and intervention for congenital muscular torticollis (CMT) in infants are crucial for improving clinical outcomes. However, in China, limited awareness of CMT among child healthcare institutions and caregivers, as well as inconsistent professional standards among rehabilitation personnel, pose significant challenges to the effective diagnosis and management of CMT. The "Physical therapy management of congenital muscular torticollis: a 2024 evidence-based clinical practice guideline from the American Physical Therapy Association Academy of Pediatric Physical Therapy" includes 17 action statements, primarily addressing the prevention, identification, assessment, and intervention of CMT. This guideline is expected to facilitate early detection of CMT in infants, enhance the treatment capabilities of physical therapists, and improve clinical outcomes. This article provides an interpretation of the guideline in the context of the current status of CMT diagnosis and management in China, aiming to offer a reference for improving the ability of primary child healthcare providers and physical therapists to recognize and manage CMTropriately.

Major depressive disorder (MDD) has become an increasingly serious public health issue, characterized by high incidence and high disability rates. It often coexists with other mental health problems and physical diseases, with a significant negative impact on patients' quality of life. In clinical practice, MDD is considered a heterogeneous disease. The complexity of the pathological mechanisms and the variability in treatment responses lead to a lack of clear therapeutic targets, which complicates the treatment process. In recent years, with advancements in neuroscience, the crucial role of microglia in the pathogenesis of MDD has been revealed. As the main immune cells in the brain, microglia are not only involved in the regulation of neuroinflammation but also play important roles in neurogenesis and neuronal regulation in MDD. This article mainly discusses the role of microglia in the pathophysiological mechanisms of MDD, aiming to provide a theoretical basis for microglia as a potential target for the treatment of MDD.

The traditional Chinese medicine （TCM） in pediatric care has a long history，proven efficacy，and distinctive characteristics.The China Association of Chinese Medicine has organized a series of youth salons to discuss the clinical advantages of treating diseases.Experts at this seminar proposed that the superior disease categories in pediatric TCM are significant for showcasing the unique strengths and advantages of TCM in the treatment of pediatric diseases，enhancing diagnostic and treatment levels，inheriting TCM knowledge，promoting the integration of TCM and Western medicine，and meeting patients' needs.The strengths of pediatric TCM are summed up as "having what others do not，excelling at what others have，being special in what others excel at，and ensuring safety in what others specialize in." The scope of superiority in pediatric TCM covers multiple systems，including respiratory，digestive，endocrine，psychological，and dermatological systems.This article summarized the advantages of TCM in treating 13 diseases discussed in the salon，such as upper respiratory tract infections，coughs，pneumonia，allergic rhinitis，bronchial asthma，atopic dermatitis，functional dyspepsia，functional constipation，enuresis，marginal short stature，simple obesity，attention deficit hyperactivity disorder，and tic disorders.The overall advantages were reflected in three aspects：First，the holistic concept and treatment based on syndrome differentiation in TCM highlight the advantage of treating the root causes of diseases，making the treatment methodical and precise.Second，most traditional Chinese herbs are natural and have strong safety profiles.Third，TCM treatment methods are abundant，especially the external treatment methods，which are widely used in pediatrics，highly accepted by parents，and have definite efficacy，as well as good safety and compliance.

Objectives:To analyze the characteristics of adjacent vertebral compression fracture(AVCF)after lumbar spinal fusion,and to investigate its treatment modality and clinical efficacy.Methods:353 patients treated with lumbar fixation and fusion for lumbar degenerative diseases at our center from January 2013 to January 2019 were retrospectively analyzed,and a total of 11 patients had AVCF after fusion,all were female,aged 70±7.2 years(61-83 years)old,including 1 case of T12 vertebral fracture,1 case of T12 combined with L1 vertebral fracture,4 cases of L1 vertebral fracture,2 cases of L2 vertebral fracture,1 case of L1 combined with L2 vertebral fracture,1 case of L3 vertebral fracture,and 1 case of L3 combined with T11 vertebral fracture.The fractures were treated accordingly based on the AVCF.characteristics,three cases underwent conservative treatments such as anti-osteoporosis due to healed fractures or other underlying diseases that were not suitable for surgery;Three cases of simple fractures without severe neurological damage symptoms were treated with percutaneous kyphoplasty(PKP)under local anesthesia;Five cases of fractures combined with lower limb nerve compression symptoms were treated with posterior revision surgery,spinal canal decompression,and upward extension and pedicle screws fixation.The mean follow-up time was 24.5±6.4 months(24-31 months).The visual analogue scale(VAS)score for low back pain and lower extremity pain and Japanese Orthopaedic Association(JOA)score for lumbar spine were performed preoperatively,1 week postoperatively,and at the final follow-up,and the occurrence of complications during the perioperative period and the follow-up were recorded.Results:The incidence of AVCF after lumbar fusion was 3.1％(11/353).The VAS score for low back pain was 5.2±2.3 preoperatively,3.5±1.8 at 1 week postoperatively(P＜0.05),and 3.9±2.0 at the final follow-up(P＜0.05);the VAS score for lower extremity pain was 7.1±2.2 preoperatively,3.0±1.6 at 1 week postoperatively(P＜0.05),and 3.7±1.9 at the final follow-up(P＜0.05);The JOA score of lumbar spine was 14.8±5.6 before operation,21.5±4.2 at one week after operation(P＜0.05)and 18.7±3.9 at the final follow-up(P＜0.05).According to the recovery rate(RR)of JOA at the final follow-up,5 cases were excellent,3 cases were good,2 cases were fair and 1 case was poor,and the satisfaction rate of clinical efficacy was 72％.A total of 4 patients(36％)had 5 complications.One patient developed a deep infection of staphylococcus aureus in the wound was treated with incision,debridement,irrigation,drainage,and sensitive antibiotics,and was cured afterward;One patient suffered from increased weakness of both lower extremities and urinary retention after surgery,and was treated with vertebral canal decompression and bone cement screw lengthening and fixation again,while after revision surgery,the patient suffered from temporary cardiac insufficiency,and recovered after treatment of salt and water restriction,cardiotonic diuresis,etc;One patient developed vertebral compression fracture after surgery and was treated with PKP bone cement reinforcement;One patient developed AVCF again and combined with intervertebral disc herniation and spinal stenosis after surgery,who underwent further revision and extended fixation.Conclusions:AVCF after lumbar fusion mostly occurs in the thoracolumbar segment and in elderly women,and simple AVCF without neurological symptoms can be treated with PKP,while AVCF with intervertebral disc herniation or spinal stenosis can be treated with lumbar revision and spinal decompression,and good clinical results can be achieved.

Objective:To evaluate the values of 18F-PI-2620 PET/CT brain imaging with SUV ratio (SUVR) in the assessment of tau protein deposition in the brain of patients with different cognitive disorders and its correlation with cognition. Methods:This was a cross-sectional study. From December 2019 to November 2022, a total of 67 subjects including 54 patients with Alzheimer′s disease (AD; 21 males, 33 females, age (68.6±7.8) years), 7 patients with mild cognitive impairment (MCI; 1 male, 6 females, age (63.1±11.2) years) and 6 healthy controls (HC; 4 males, 2 females, age (69.0±5.8) years) were enrolled retrospectively in Renji Hospital. All participants were examined by 18F-PI-2620 PET/CT. SUVRs of brain regions were obtained, including frontal lobe, temporal lobe, occipital lobe, parietal lobe, insular lobe, whole brain, as well as 10 independent brain ROIs (amygdala, orbitofrontal cortex, cingulate gyrus, superior occipital gyrus, superior parietal gyrus, inferior angular gyrus, precuneus, inferior temporal gyrus, entorhinal cortex and parahippocampal gyrus), with inferior cerebellum cortex as the reference region. All participants were estimated by cognitive scales(mini-mental state examination (MMSE) and Montreal cognitive assessment (MoCA)). One-way analysis of variance and the least significant difference t test were used to compare the differences of SUVR in each brain region among HC, MCI and AD groups. ROC curve analysis was used to determine the optimal cut-off values of SUVR in each brain region for the differential diagnosis of AD-MCI and AD-HC. Pearson correlation analysis was employed to examine the correlations of SUVR with cognitive scale scores. Results:The SUVR of whole brain was 1.40±0.31 in AD group, 1.08±0.19 in MCI group, and 1.01±0.12 in HC group. SUVR analysis in the whole brain and each brain region could distinguish AD from HC, AD from MCI ( F values: 1.76-10.09, t values: 2.98-7.47, all P<0.05), but could not distinguish HC from MCI ( t values: 0.17-1.53, all P>0.05). ROC curve analysis showed that the best cut-off value of SUVR was 1.18 for whole brain (AUC=0.89), 1.13 for amygdala (AUC=0.94) and 1.26 for parahippocampal gyrus (AUC=0.94) for differential diagnosis of AD and HC, which was 1.06 for whole brain (AUC=0.82), 1.18 for amygdala (AUC=0.88) and 1.28 (AUC=0.88) for infratemporal gyrus to differential diagnosis of AD and MCI. SUVRs of the whole brain, frontal, occipital, parietal, temporal and insula were significantly negatively correlated with MMSE and MoCA cognitive scale scores ( r values: from -0.64 to -0.40, all P<0.05). Conclusions:SUVR quantitative analysis in 18F-PI-2620 PET imaging can assist the differential diagnosis of AD and HC, AD and MCI. The SUVRs of whole brain and five lobes show negative correlations with MMSE and MoCA scores.

Objective:To assess the diagnostic efficiency of 18F-FDG PET for Alzheimer′s disease (AD) in patients with memory impairment. Methods:A retrospective analysis was conducted on 96 patients (40 males, 56 females, age: 69.0(62.8, 74.0) years) initially diagnosed with memory impairment in Renji Hospital, School of Medicine, Shanghai Jiao Tong University between August 2019 and September 2023. The amyloid-tau-neurodegeneration (ATN) criteria, based on 18F-AV45+ 18F-PI-2620 PET/CT+ MRI imaging results, were used as the diagnostic standard for AD. Visual analysis (temporoparietal or posterior cingulate cortex (PCC) hypometabolism) and semi-quantitative analysis methods (PET-SCORE and NeuroQ software analysis (SUV ratio, SUVR)) were applied to evaluate the diagnostic efficiency of 18F-FDG PET imaging for AD. Diagnostic efficiencies of visual assessment and semi-quantitative parameters were compared by χ2 test. Additionally, Pearson correlation analysis was performed to examine the relationship between results of PET-SCORE and cognitive scales. Results:Of the 96 patients initially diagnosed with memory impairment, 61 were clinically diagnosed with AD, while 35 were non-AD patients. Visual assessment of temporoparietal hypometabolism showed the highest sensitivity (91.80%, 56/61), which was significantly different from the sensitivities of PET-SCORE (40.98%(25/61); χ2=29.03, P<0.001) and visual assessment of PCC hypometabolism (77.05%(47/61); χ2=5.82, P=0.016). While semi-quantitative assessment using PET-SCORE demonstrated the highest specificity (100%, 35/35), which was significantly different from the specificities of visual assessment methods (temporoparietal hypometabolism: 17.14%(6/35), χ2=27.03, P<0.001; PCC hypometabolism: 54.29%(19/35), χ2=14.06, P<0.001). PET-SCORE exhibited statistically significant correlations with Mini-Mental State Examination (MMSE), Montreal Cognitive Assessment (MoCA), and Activities of Daily Living (ADL) scores ( r values: -0.38, -0.36, 0.31, all P<0.01). Conclusions:Among patients initially diagnosed with memory impairment, visual assessment in 18F-FDG PET imaging analysis demonstrates higher sensitivity, while semi-quantitative analysis using PET-SCORE exhibits higher specificity. PET-SCORE shows statistically significant correlation with the severity of cognitive decline.
