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.

Bone formation and deposition are initiated by sensory nerve infiltration in adaptive bone remodeling.Here,we focused on the role of Semaphorin 3A(Sema3A),expressed by sensory nerves,in mechanical loads-induced bone formation and nerve withdrawal using orthodontic tooth movement(OTM)model.Firstly,bone formation was activated after the 3rd day of OTM,coinciding with a decrease in sensory nerves and an increase in pain threshold.Sema3A,rather than nerve growth factor(NGF),highly expressed in both trigeminal ganglion and the axons of periodontal ligament following the 3rd day of OTM.Moreover,in vitro mechanical loads upregulated Sema3A in neurons instead of in human periodontal ligament cells(hPDLCs)within 24 hours.Furthermore,exogenous Sema3A restored the suppressed alveolar bone formation and the osteogenic differentiation of hPDLCs induced by mechanical overload.Mechanistically,Sema3A prevented overstretching of F-actin induced by mechanical overload through ROCK2 pathway,maintaining mitochondrial dynamics as mitochondrial fusion.Therefore,Sema3A exhibits dual therapeutic effects in mechanical loads-induced bone formation,both as a pain-sensitive analgesic and a positive regulator for bone formation.

Objective To investigate the preparation and evaluation of animal models of depression associated with autoimmune thyroiditis,and to verify the NLRP3/Caspase-1/GSDMD pathway based on this condition.Methods 32 NOD.H-2H4 mice were randomly divided into a normal(N)group,depression(DP)group,autoimmune thyroiditis with depression(AIT+DP)group,autoimmune thyroiditis(AIT)group,with 8 animals in each group.The N group was fed normally,the DP group was subjected to chronic unpredictable mild stress(CUMS)for 5 weeks,the AIT group was given 0.05％sodium iodide water to establish an autoimmune thyroiditis model,and the AIT+DP group was subjected to 5 weeks of CUMS to establish the AIT animal model.We evaluated whether the mouse autoimmune thyroiditis model had been successfully prepared by observing the thyroid tissue structure,lymphocyte infiltration,and serum TGAb and TPOAb levels.Changes in body weight,sugar water preference rate,open field behavior(central quadrant time,central quadrant time proportion,standing rate,frequency of defecation,and hair grooming time),and hippocampal pathological changes were used to evaluate the depression status of the mice.When the model mice met the above-mentioned indicators related to depression and autoimmune thyroiditis,the AIT+DP animal model was considered successfully prepared.Results Compared with the levels in the N group,the AIT group's and AIT+DP group's serum TGAb and TPOAb levels were significantly increased(P＜0.01),and a large number of inflammatory cells had infiltrated the thyroid gland.The central quadrant time and central quadrant time proportion,standing rate,frequency of defecation,and hair grooming time were reduced to varying degrees in the DP group and AIT+DP group.In addition,the numbers of glial cells in the cerebral cortex increased and neuronal cells decreased,accompanied by some nuclear atrophy,and the expression levels of NLRP3,IL-1β,Caspase-1,and GSDMD-N significantly increased,especially in the AIT+DP group(P＜0.01).Conclusions 0.05％sodium iodide water and CUMS create autoimmune thyroiditis with depression model animals that better simulate the external performance and internal index changes of the diseases.These mice can provide an animal model reference for research into autoimmune thyroiditis with depression.

Objective To evaluate the efficacy,safety and economy of cyclin-dependent kinase 4/6(CDK4/6)inhibitors for the first-line treatment of hormone receptors positive(HR+),human epidermal growth factor receptor 2 negative(HER2-)advanced breast cancer(ABC)by rapid health technology assessment,and to provide evidence for clinicians and policymakers.Methods PubMed,Cochrane Library,Embase,CNKI,WanFang Data,VIP databases and the official website of health technology assessment(HTA)agency were electronically searched to collect clinical evidence and literature of CDK4/6 inhibitors in the treatment of HR+/HER2-ABC from the inception to December 31,2023.Two reviewers independently identified studies,extracted data,assessed the quality of included studies,and descriptively analyzed and summarised the results.Results A total of 33 articles were included,including 9 systematic reviews/Meta-analyses,15 pharmacoeconomic studies and 9 HTA reports.In terms of efficacy,compared with endocrine therapy alone,the addition of CDK4/6 inhibitors significantly improved progression-free survival(PFS)and overall survival(OS)in patients with HR+/HER2-ABC(P＜0.05),but there was no significant difference in efficacy among palbociclib,abemaciclib and ribociclib(P＞0.05).In terms of safety,more adverse events were observed in patients treated with CDK4/6 inhibitors when compared with endocrine therapy(P＜0.05).There was a difference in the incidence of adverse effects between the different CDK4/6 inhibitors,with palbociclib having higher incidence of haematological adverse effects(P＜0.05),and abemaciclib being more likely to cause gastrointestinal adverse reactions such as diarrhoea(P＜0.05).The economic evaluation results were variable due to differences in healthcare costs,analysis perspectives,willingness-to-pay thresholds,and study duration in different countries.Conclusion CDK4/6 inhibitors have similar efficacy in the first-line treatment of HR+/HER2-ABC patients,but there are some differences in aspects such as safety and economy.
