In recent years, neuromodulation technology has gradually evolved from exploratory research, animal experiments, and large-sample multicenter randomized controlled trials to become a routine treatment in clinical psychiatry. Neuromodulation methods have also developed from the initial electrical stimulation to various modes of stimulation such as magnetic stimulation, optical stimulation, and ultrasound stimulation. Neuromodulation has gradually become the third effective intervention for mental disorders, alongside medicine and psychotherapy, and is one of the most popular and promising field of clinical psychiatric treatment for the present and the future. Therefore, this article discusses the overall development status of current neuromodulation technology in psychiatry and the overall progress of common neuromodulation techniques, propose some key issues that need to be resolved and the prospects for clinical development in neuromodulation technology, to provide a reference for the research and clinical application of neuromodulation technology in psychiatry.

To investigate the pharmacological substances basis and anti-vitiligo mechanism of Carum carvi L. (caraway) fruits, chemical and blood-absorbed components were identified using mass spectrometry combined with literature study and database analysis. A “blood-absorbed components–target genes–pathways” network was constructed through network pharmacology. The pharmacological effects of Carum carvi L. extract and its key blood-absorbed component, acacetin, were validated in vitro. 72 chemical components were identified in the extract, with 11 prototype blood-absorbed components and 26 metabolites being detected in the plasma of SD rats. 14 key active components and 24 key targets were predicted. In vitro experiments demonstrated that acacetin at 10 μmol/L exhibited melanogenesis-promoting and tyrosinase-activating effects compared with the positive control, significantly upregulating the expression of microphthalmia-associated transcription factor (MITF) and tyrosinase (tyrosinase, TYR). This study comprehensively analyzes the chemical and blood-absorbed components of Carum carvi L. and elucidates its pharmacological substances basis, which provides a theoretical foundation for the anti-vitiligo effects of acacetin.

Objective:To establish the quality standard of the standard decoction of wine-processed Coptidis Rhizoma by studying the extraction rate, fingerprint and component quantitative analysis.Methods:ccording to the Technical Requirements for Quality Control and Standard Formulation of Chinese Medicine Formula Granules, 15 batches of the standard decoction of wine-processed Coptidis Rhizoma were prepared, and the paste rate was determined; HPLC fingerprints of 15 batches of standard decoction of wine-processed Coptidis Rhizoma were established, and evaluated by combining similarity evaluation, clustering analysis, principal component analysis and orthogonal partial least squares discriminant analysis; the contents of berberine, epiberberine, pamadine, and safranine in the samples of the 15 batches were determined and analyzed their transfer rates.Results:A total of 15 batches of standard decoction samples were calibrated with 11 common peaks, referring to the recognition of 8 components. The similarity between the samples and the control product was greater than 0.900; the clustering analysis could cluster the 15 batches of samples into 2 classes; the results of the principal component analysis showed that the cumulative variance contribution rate of the 3 principal component factors was 89.388%; the OPLS-DA screened out the 3 components of the quality difference; the 15 batches of samples out of the paste rate was 15.7% -20.8%, and the mass fractions of berberine, epiberberine, safranine, and palmatine were 18.47%-24.38%, 2.82%-3.49%, 5.08%-6.69%, and 4.84%-6.68%, respectively, with transfer rates of 41.7%-61.7%, 46.9%-68.7%, 39.8%-61.5%, and 43.8%-65.2%.Conclusion:The fingerprint and content determination method established in this study is accurate, stable, simple, and can be used for the quality control and evaluation of the standard decoction of wine-processed Coptidis Rhizoma.

Objective:To explore the mechanism of how neurocognition affects social functioning through fa-cial emotion recognition in individuals with schizophrenia.Methods:Totally 203 patients with schizophrenia meet-ing the Diagnostic and Statistical Manual of Mental Disorders,Fourth Edition(DSM-IV)diagnostic criteria were re-cruited,with an age of(40±12)years,an initial onset age of(24±8)years,scored(60.4±16.1)points on the Positive and Negative Syndrome Scale.Using the Personal and Social Performance Scale(PSP),the MATRICS Consensus Cognitive Battery(MCCB),and the Facial Emotion Recognition Test(FERT)to assess patients'social functioning,neurocognition,and facial emotion recognition abilities.Results:In the relationship between MCCB fac-tor scores and PSP dimensions scores,happy face recognition showed a mediating effect in socially useful activities dimension(ACME=0.021,P＜0.01),sad(ACME=-0.026,P＜0.05)and surprised face recognition(ACME=-0.017,P＜0.05)showed mediating effects in self-care dimension.Additionally,sad(ACME=-0.025,P＜0.05)and fearful face recognition(ACME=-0.025,P＜0.001)played a mediating role in disruptive and aggres-sive behavior dimensions.Conclusion:Facial emotion recognition in patients with schizophrenia may play a media-ting role in the neurocognitive mechanisms of social dysfunction,with different dimensions of social dysfunction be-ing associated with specific categories of emotions.

Objective:To investigate the effectiveness of suicide prevention cognitive behavioral therapy for depression patients with suicide attempt.Methods:Eligible participants were recruited from the inpatient department of Beijing Huilongguan Hospital from September 2021 to August 2022. A total of 112 patients were randomly allocated into the intervention group (56 cases) and the control group (56 cases) by a random number table. Patients in the intervention group received 12 sessions of cognitive behavioral therapy for suicide prevention over 8 weeks,while participants in the control group received supportive psychotherapy. Patient Health Questionnaire Depression Scale (PHQ-9) and the Beck Scale for Suicide Ideation-Chinese Version (BSI-CV) were used to assess changes in depressive symptoms,suicidal ideation,and suicidal tendencies in both groups at baseline,4-week of treatment,the end of treatment,and at follow-up (weekends 4,8,12). General data and scale scores between the two groups were analyzed by t test,Mann-Whitney rank sum test,and χ 2 test; repeated measure ANOVA were used to assess the baseline and intervention effects. Results:The change of PHQ-9 at each time point of the 2 groups showed a downward trend,and the group x time interaction was significant ( F=2.75, P=0.047). Since the 8th week,the PHQ score in the intervention group was significantly lower than that in the control group ( t=7.03, P<0.05). Time and group effect were significant in the four time points of the total score of suicidal ideation in the last week in BSI-CV ( F=96.78,6.35,both P<0.05),but the interaction between group and time was not significant. At weeks 8 and 12,the scores of the intervention group were lower than those of the control group ( Z=-3.11,-3.30;both P<0.01). In BSI-CV,time effects in the total score of suicidal intention was significant at four time points ( F=11.83, P<0.05),but the interaction between group and time was not significant ( F=2.56, P=0.059). There was no significant difference in suicide tendency between the two groups at each time point ( F=0.001, P=0.975). The total scores of suicidality in 2 groups at 4,8 and 12 weeks were all lower than baseline ( P<0.05). Conclusions:Compared with the control group,the cognitive behavioral therapy for suicide prevention showed superior effects on suicidal ideation and depression,but the intervention effect on suicidal tendency was not significant. Further studies are needed to investigate the long-term effects of cognitive behavioral therapy for suicide prevention in patients with depression who have attempted suicide.

Objective:To explore the relation of depressive and anxiety symptoms to defense mechanism in transgender population.Methods:Totally 451 transgender patients in the sexual and psychological outpatient depart-ment of a hospital were selected.They were assessed with the self-Rating Depression Scale(SDS),Self-Rating Anxiety Scale(SAS)and Defense Mechanism Scale(DSQ).The SDS standard score of ≥53 was classified as having depressive symptoms,and the SAS standard score of ≥50 was classified as having anxiety symptoms.Re-sults:The detection rates of depression and anxiety were 46.8％and 28.8％respectively.Multiple linear regression analysis showed that SDS scores were positively correlated with DSQ scores of projection,conceit,complaint,with-drawal,somatization,control,isolation and identity(β=0.08-0.22),while SDS scores were negatively correlated with DSQ scores of sublimation,depression,omnipotence with incompetence and denial(0=-0.09--0.19).The SAS scores were positively correlated with the DSQ scores of projection,latent manifestation,somatization,control,isolation,identity,and consumption tendency(0=0.09-0.26),while the SAS scores were negatively cor-related with the DSQ scores of sublimation,depression,omnipotence accompanied by incompetence,and denial(β=-0.09--0.15).Conclusion:The proportion of depression and anxiety symptoms detected in the transgender group is higher,which may be related to the use of some defenses.
