ObjectiveMicrotube associated protein-2 （MAP-2）， alpha-tubulin （α-tubulin）， and synaptophysin （SYP） are important proteins in neuronal signal communication. This paper observed the effects of modified Zhigancao Tang on the expression of serum α-Synuclein （α-Syn） and its oligomers， MAP-2， α-tubulin， and SYP of patients with liver and kidney deficiency of Parkinson's disease （PD）， analyzed their correlation， and evaluated the therapeutic effect of modified Zhigancao Tang in patients with liver and kidney deficiency of PD based on α-Syn transmission pathway mediated by neuronal communication in vivo. MethodsA total of 60 patients with PD who met the inclusion criteria were randomly divided into a treatment group （30 cases） and a control group （30 cases）. Both groups were treated on the basis of PD medicine， and the treatment group was treated with modified Zhigancao Tang. Both groups were treated for 12 weeks. The changes in UPDRS score， TCM syndrome score， and expression of serum α-Syn and its oligomers， MAP-2， α-tubulin， and SYP were observed before and after 12 weeks of treatment in each group. The correlation between the above-mentioned serum biological indexes and the levels of serum α-Syn and its oligomers was analyzed. ResultsAfter treatment， the TCM syndrome score， UPDRS score， UPDRS-Ⅱ score， and UPDRS-Ⅲ score of the treatment group were significantly decreased （P<0.05， P<0.01）. The UPDRS score， UPDRS-Ⅱ score， and UPDRS-Ⅲ scores in the treatment group were significantly decreased compared with those in the control group after treatment （P<0.05）. After treatment， the total effective rate of the control group was 63.3% （19/30）， and that of the treatment group was 86.7% （26/30）. The clinical effect of the observation group was better than the control group （Z=-2.03， P<0.05）. The total effective rate of the observation group was better than that of the control group， and the difference was statistically significant （χ²=5.136， P<0.05）. After treatment， the oligomer level of serum α-Syn and MAP-2 level in the treatment group were significantly decreased （P<0.05， P<0.01）. The levels of serum α-Syn and its oligomers， as well as α-tubulin in the treatment group， were significantly decreased compared with those in the control group after treatment （P<0.05， P<0.01）. Serum α-Syn was correlated with serum MAP-2 and α-Syn oligomer in patients with PD （P<0.05， P<0.01） but not correlated with serum SYP . Serum α-Syn oligomers of patients with PD were correlated with serum MAP-2 and α-tubulin （P<0.05， P<0.01） but not correlated with serum SYP level. Serum SYP of patients with PD was correlated with serum MAP-2 （P<0.05）. ConclusionModified Zhigancao Tang has a therapeutic effect on patients with liver and kidney deficiency of PD by inhibiting the production of α-Syn oligomers and intervening α-Syn microtubule transport pathway in vivo.

BACKGROUND:Degeneration of nucleus pulposus cells is a key component of intervertebral disc degeneration.Ferroptosis,a novel form of programmed cell death,is closely associated with the onset and progression of intervertebral disc degeneration;however,its precise mechanisms remain unclear.OBJECTIVE:To establish an oxidative stress model in vitro by inducing ferroptosis in nucleus pulposus cells using tert-butyl hydroperoxide and to investigate the mechanisms of tert-butyl hydroperoxide-induced ferroptosis in nucleus pulposus cells,thereby elucidating the role of ferroptosis in the pathogenesis of intervertebral disc degeneration.METHODS:Nucleus pulposus cells were treated with varying concentrations of tert-butyl hydroperoxide(0,25,50,100,and 200 μmol/L),and cell morphology and viability were assessed using fluorescence microscopy and the cell counting kit-8 assay.Interventions with 100 μmol/L tert-butyl hydroperoxide,10 μmol/L RSL3,or dimethylsulfoxide were applied to nucleus pulposus cells,and cell proliferation was evaluated using the EdU assay.The expression levels of ferroptosis-related proteins(glutathione peroxidase 4,ferritin heavy chain 1,PTGS2,and ACSL4)and intervertebral disc degeneration marker proteins(matrix metalloproteinase 13 and Col2A)were analyzed via western blot and immunofluorescence.Additionally,reactive oxygen species and lipid peroxidation levels were quantified using the reactive oxygen species detection kit and C11-BODIPY probe.Mitochondrial morphological changes were observed under transmission electron microscopy.RESULTS AND CONCLUSION:(1)tert-Butyl hydroperoxide treatment significantly reduced the viability and proliferation of nucleus pulposus cells.(2)tert-Butyl hydroperoxide induced typical ferroptosis-related morphological changes in nucleus pulposus cells.(3)tert-Butyl hydroperoxide exposure led to a decrease in the expression of ferroptosis-suppressing proteins glutathione peroxidase 4 and ferritin heavy chain 1,while increasing the expression of ferroptosis-promoting factors ACSL4 and PTGS2.(4)tert-Butyl hydroperoxide elevated intracellular reactive oxygen species production and lipid peroxidation levels in nucleus pulposus cells.(5)Transmission electron microscopy revealed ferroptosis-specific mitochondrial changes in nucleus pulposus cells treated with tert-butyl hydroperoxide,including contraction,reduced cristae,and increased membrane density.(6)tert-Butyl hydroperoxide treatment also resulted in the increased expression of matrix metalloproteinase 13 and decreased expression of Col2A in nucleus pulposus cells.In conclusion,tert-butyl hydroperoxide induces ferroptosis in nucleus pulposus cells,contributing to the development of intervertebral disc degeneration.This process may represent a key pathological mechanism in intervertebral disc degeneration and offers potential targets for developing novel therapeutic strategies.

Objective:To explore the clinical characteristics and therapeutic effect of perioral myoclonia with absences (PMA), in order to improve the clinicians′ understanding of the disease.Methods:The clinical manifestations during seizures, as well as interictal and ictal electroencephalogram (EEG) features of 3 PMA patients admitted to the Epilepsy Unit, Neurology Center, Beijing Tiantan Hospital, Capital Medical University from May to October 2024 were analyzed. The clinical manifestations, EEG characteristics, differential diagnosis, treatment experience of PMA patients were summarized by retrospective analysis combined with previous literature review.Results:The onset age of these 3 PMA cases was 15, 15, and 7 years, respectively. The prominent manifestation of seizure was perioral myoclonus without disturbance of consciousness. The duration of seizures was brief, less than 10 seconds. PMA can occur several times a day and was prone to present as continuous state of perioral myoclonus. Three patients had rare generalized tonic-clonic seizures (GTCS). The seizures could be controlled by sodium valproate, lamotrigine, levetiracetam, or combined treatment. Fifteen literatures about PMA were retrieved (4 in Chinese and 11 in English). A total of 31 patients (including these 3 patients) were included in the study, of whom 17 were males and 14 were females. The onset age was from 9 months to 34 [7.63 (2.19, 11.00)] years. Perioral myoclonus with varying degrees of disturbance of consciousness was the main seizure type, and 12 patients exhibited continuous state of perioral myoclonus, 24 patients had GTCS. Eight patients had a history of fever convulsion, 6 patients had mental or learning disabilities, and 11 patients had a family history of epilepsy or febrile convulsion. The ictal EEG showed around 3 Hz generalized spike-wave/multiple spike-wave discharges accompanied with synchronous myoelectric bursts. There were no specific abnormalities in physical examination of nervous system and cranial imaging in all the patients. Ten patients were initially diagnosed as focal epilepsy. Nine patients′ seizures were increased or worsened due to improper medication. Valproate, lamotrigine and levetiracetam were the main treatments of PMA, and the seizures of 21 patients were effectively controlled.Conclusions:PMA is clinically characterized by perioral myoclonia with varying degrees of disturbance of consciousness and is easy to be misdiagnosed as focal epilepsy, so it is necessary to use video EEG combined with synchronous electromyography to confirm the diagnosis. PMA should be treated with broad-spectrum antiseizure drugs.

A 20-year-old male patient presented to the Department of Dermatology of Peking Union Medical College Hospital with complaints of an 8-year history of facial scarring, swelling of the lower limbs, and a 4-year history of scalp thickening. Physical examination showed thickening furrowing wrinkling of the skin on the face and behind the ears, ciliary body hirsutism, blepharoptosis, and cutis verticis gyrate. Both lower limbs were swollen, especially the knees and ankles. The skin of the palms and soles of the feet was keratinized and thickened. Laboratory examination using bone and joint X-ray showed periostosis of the proximal middle phalanges and metacarpals of both hands, distal ulna and radius, tibia and fibula, distal femurs, and metatarsals.Genetic testing revealed two variants in SLCO2A1, c.1658T > A and c.96+4A > C.Through multidisciplinary consultation, we confirmed the diagnosis of pachydermoperiostosis.

Objective:To discuss the role of changes of serum total bile acid(TBA)levels induced by long-term high-fat diet in the occurrence of supraventricular arrhythmia(SVA)in the apolipoprotein E knockout(ApoE-/-)mice,and to clarify its mechanism.Methods:Twenty ApoE-/-mice were randomly divided into normal diet group and high-fat diet(HFD)group(n=10);after 20 weeks of feeding,surface electrocardiogram was used to detect cardiac electrophysiology of the mice in various groups;echocardiography was used to detect cardiac systolic function and structure in the mice in various groups;enzyme-linked immunosorbent assay(ELISA)was used to detect serum levels of blood lipids,total bile acid(TBA)and inflammatory factors in the mice in various groups;hematoxylin-eosin(HE)staining was used to detect cardiac inflammatory response in the mice in various groups;Masson staining was used to observe myocardial fibrosis degree in the mice in various groups.Results:Compared with normal diet group,4 cases of junctional premature beat(JPB)/junctional tachycardia(JT),1 case of premature atrial contraction(PAC)and 1 case of premature ventricular contraction(PVC)were found in HFD group,while only 1 case of JPB/JT and 1 case of PAC were found in normal diet group.Compared with normal diet group,the heart rate of the mice in HFD group was significantly decreased(P<0.05);the QRS and QT intervals were significantly prolonged(P<0.05);the ejection fraction(EF)and fractional shortening(FS)were significantly decreased(P<0.05);the end-diastolic volume(EDV)was increased(P<0.05),but there was no significant difference in end-systolic volume(ESV)between groups(P>0.05);the left ventricular internal diameter at end-diastole(LVIDd)and left ventricular internal diameter at end-systole(LVIDs)were significantly increased(P<0.05).There were no significant differences in plasma total cholesterol(TC),triglyceride(TG),high-density lipoprotein(HDL-c)and low-density lipoprotein(LDL-c)levels and body weight between normal diet group and HFD group(P>0.05).Compared with normal diet group,the TBA level of the mice in HFD group was significantly increased(P<0.05).There were no significant differences in interleukin-6(IL-6),tumor necrosis factor-α(TNF-α),monocyte chemoattractant protein-1(MCP-1),and C-X-C motif chemokine ligand 1(CXCL-1)levels between HFD group and normal diet group.Compared with normal diet group,the interleukin-1β(IL-1β)level in HFD group showed an increasing trend,but there was no significant difference between groups(P>0.05).The HE staining results showed that the inflammatory cell infiltration was similar between HFD group and normal diet group.The Masson staining results showed that compared with normal diet group,the fibrosis of the mice in HFD group showed an increasing trend,but there was no significant difference in myocardial fibrosis area between groups(P>0.05).Conclusion:Long-term high-fat diet may increase serum TBA level in ApoE-/-mice,which may induce SVA.
