Depression is a prevalent mental and emotional disor-der that often results in significant emotional disturbances,cog-nitive dysfunction,and memory impairments.It is characterized by a high incidence rate,a substantial disability burden,and limited therapeutic efficacy.Currently,the long-term use of medications for the treatment of depression can result in a range of adverse reactions,highlighting the urgent need to explore no-vel approaches that can effectively alleviate depressive symptoms while minimizing side effects.Curcumin,a natural polyphenolic compound derived from the rhizome of turmeric,demonstrates considerable potential in the prevention and treatment of depres-sion,owing to its diverse array of biological activities.In recent years,numerous studies have investigated the use of curcumin for the treatment of depression.This article aims to provide a comprehensive review of the mechanisms of action underlying curcumin's efficacy in treating depression.Specifically,it focu-ses on its ability to improve neurotransmitter imbalances,restore neural plasticity,alleviate neural damage,mitigate dysfunction of the hypothalamic-pituitary-adrenal(HPA)axis,regulate in-flammatory factors and neuroinflammatory signaling pathways,and inhibit oxidative stress.This review is intended to offer in-sights and methodological references for basic research on curcu-min,as well as for the development of novel therapeutic agents for the treatment of depression.

Objective:To analyze the imaging features of testicular conventional ultrasonography（US），shear wave elastography（SWE），and contrast-enhanced ultrasonography（CEUS）in subtypes of spermatogenic dysfunction（focal，arrest，and exhausted），and to evaluate the diagnostic efficacy of testicular multimodal ultrasound.Methods:A prospective study enrolled 310 spermatogenic dysfunction patients（focal type group： n=77，arrest type group： n=20，exhaustive type group： n=213）and 30 healthy volunteers（control group）at Shanghai General Hospital between October 2023 and December 2024. All patients underwent preoperative testicular US，SWE，and CEUS examinations，followed by microdissection testicular sperm extraction. Ultrasound parameters were compared among groups，and receiver operating characteristic（ROC）curves were plotted to assess the diagnostic efficacy of multimodal ultrasound for different subtypes. Results:①Testicular volume：The arrest group exhibited significantly greater volume compared to the focal group and the exhausted group（all P<0.05）. No statistically significant difference was observed between the arrest group and the normal group（ P>0.05）. ②Mean Young's modulus（Emean）：The arrest group exhibited significantly lower Emean compared with both the focal and exhausted groups（all P<0.05），but showed no significant difference versus the normal group（ P>0.05）. ③CEUS quantitative parameters：The arrival time（AT）and time to peak（TTP）in the exhausted group were higher than those in the normal group，while the peak intensity（PI）and area under the time-intensity curve（AUC）were lower（all P<0.05）. No significant differences were found in AT，TTP，or AUC among the three spermatogenic dysfunction subgroups（all P>0.05）. ④CEUS perfusion patterns：The focal group predominantly exhibited a mottled pattern（70.13%，54/77）. Both the arrest group（90.00%，18/20）and the normal group（93.33%，28/30）predominantly exhibited an rich pattern. The exhausted group predominantly exhibited a sparse pattern（56.34%，120/213）. ⑤ROC curve analysis showed that for differentiating the arrest group from the focal type group and the exhaustive type group，the combination of Emean，testicular volume，and CEUS perfusion pattern yielded an AUC of 0.931，with a sensitivity of 95.00% and specificity of 85.86%. For differentiating the focal type group from the exhaustive type group，the combination of testicular echogenicity，CEUS perfusion pattern，and Emean yielded an AUC of 0.833，with a sensitivity of 81.82% and specificity of 75.12%. Conclusions:Multimodal ultrasonography can comprehensively characterize the imaging features of different subtypes of spermatogenic dysfunction，holding promise as a noninvasive predictive tool.

The comparison between traditional Chinese medicine Jinzhen oral liquid (JZOL) and Western medicine in treating children with acute bronchitis (AB) showed encouraging outcomes. This trial evaluated the efficacy and safety of the JZOL for improving cough and expectoration in children with AB. 480 children were randomly assigned to take JZOL or ambroxol hydrochloride and clenbuterol hydrochloride oral solution for 7 days. The primary outcome was time-to-cough resolution. The median time-to-cough resolution in both groups was 5.0 days and the antitussive onset median time was only 1 day. This randomized controlled trial showed that JZOL was not inferior to cough suppressant and phlegm resolving western medicine in treating cough and sputum and could comprehensively treat respiratory and systemic discomfort symptoms. Combined with clinical trials, the mechanism of JZOL against AB was uncovered by network target analysis, it was found that the pathways in TRP channels like IL-1β/IL1R/TRPV1/TRPA1, NGF/TrkA/TRPV1/TRPA1, and PGE2/EP/PKA/TRPV1/TRPA1 might play important roles. Animal experiments further confirmed that inflammation and the immune regulatory effect of JZOL in the treatment of AB were of vital importance and TRP channels were the key mechanism of action.

【Objective】 To explore the expression of USP9X in platelets and its effect on platelet function. 【Methods】 The expression of USP9X in human and mouse was evaluated by PCR and Western blot. Platelets from young and old mice were separated and prepared, and the expression of USP9X was detected. USP9X inhibitos were used to assess the regulation of USP9X in platelet function, including aggregation, ATP release and spreading. Platelet lysates were collected in different time points to evaluate the change of phosphorylation of Akt in USP9X inhibitors treated platelets. 【Results】 Both human and mouse platelets expressed USP9X. Compared to the young mice, the old mice showed significantly enhanced expression of USP9X(P<0.05). To assess the effect of USP9X on platelet function, USP9X inhibitor was used to pre-incubate platelets for 30 min and platelet function were examined later. Results showed that USP9X inhibitor significantly decreased platelet activation including aggregation, ATP release and spreading(P<0.05). Compared to the control group, the inhibitor treated group showed a significant decrease in the spreading area after 45 minutes. The Western blot results showed a significant decrease in Akt phosphorylation levels of platelets in the USP9X inhibitor treated group. 【Conclusion】 Both human and mouse platelet express USP9X, and inhibition of USP9X decreased platelet function including aggregation, ATP release and spreading. USP9X can also influence the phosphorylation of Akt. The inhibitor of USP9X may become a potential therapeutic target for thrombosis intervention.

Objective To explore the relationship and internal path between activities of daily living(ADL),sleep quality and mental health of community elderly people in Shanghai.Methods A questionnaire survey was conducted among community residents aged 60 years and older seeing doctors in community health care center of five streets in Shanghai during Sept to Dec,2021 using convenience sampling.Activities of Daily Living(ADL),Pittsburgh Sleep Quality Index(PSQI)and 10-item Kessler Psychological Distress Scale(K10)were adopted in the survey.Single factor analysis,correlation analysis and multiple linear regression were used to analyze the data.The effect relationship between the variables was tested using Bootstrap's mediated effects test.Results A total of 1 864 participants were included in the study.The average score was 15.53±4.47 for ADL,5.60±3.71 for PSQI and 15.50±6.28 for K10.The rate of ADL impairment,poor sleep quality,poor and very poor mental health of the elderly were 23.6%,27.3%,11.9%and 4.9%,respectively.ADL and sleep quality were all positively correlated with mental health(r=0.321,P＜0.001;r=0.466,P＜0.001);ADL was positively correlated with sleep quality(r=0.294,P＜0.001).Multiple linear results of factors influencing mental health showed that ADL(β= 0.457,95%CI:0.341-0.573),sleep quality(β =0.667,95%CI:0.598-0.737)and mental health were positively correlated(P＜0.001).Sleep quality partially mediated the relationship between ADL and mental health(95%CI:0.078-0.124)with an effect size of 33.0%.Conclusion Sleep quality is a mediator between ADL and mental health among community elderly people.Improving ADL and sleep quality may improve mental health in the population.

For the treatment of atrial fibrillation,Professor WU Wei innovatively put forward the theory of heart-blood-vessels trinity and the theory of stasis-toxin causing palpitation.It is believed that atrial fibrillation is caused by stasis and toxin,and affects the heart,blood and vessels.The core pathogenesis of atrial fibrillation is due to qi stagnation,blood stasis and toxin.The treatment for atrial fibrillation should be closely based on the pathogenesis,the therapeutic principles of treating from the perspective of stasis and together by removing toxin gradually is advocated.And the therapy of regulating qi,activating blood and removing stasis is also the way to remove toxin.The medication is based on the modified Taoren Honghua Decoction,which is mainly composed of Persicae Semen,Carthami Flos,Chuanxiong Rhizoma,Corydalis Rhizoma,Rehmanniae Radix,Paeoniae Radix Rubra,Salviae Miltiorrhizae Radix et Rhizoma,Jujubae Fructus,Puerariae Lobatae Radix,Nardostachyos Radix et Rhizoma,Ostreae Concha,Poria,and Polygonati Odorati Rhizoma.According to the characteristics of Lingnan climate and atrial fibrillation mostly being easy to affect the emotions,the pungent drugs in the prescription are usually removed,and the specific herbal pair of Puerariae Lobatae Radix-Nardostachyos Radix et Rhizoma is added to remove toxin according to the differentiation of disease.Moreover,for the treatment of atrial fibrillation,Professor WU Wei also adopts traditional Chinese medicine(TCM)external treatment such as foot bath,acupuncture and moxibustion,and physical-breathing exercise as well as health-care methods for comprehensive regulation,relieving the toxin and restoring the original qi.During the treatment atrial fibrillation,Professor WU Wei follows the principle of precise intervention and comprehensive regulation with Chinese medicine,so as to achieve the purpose of eliminating symptoms,restoring sinus rhythm and improving physical constitution.The thoughts of Professor WU Wei for the syndrome differentiation and treatment of atrial fibrillation will provide reference for the treatment of atrial fibrillation with TCM.
