[Effects of Shugan Tiaoshen intradermal needling intervention on attentional networks in subthreshold depression: a randomized controlled trial].

OBJECTIVE: To analyze the effects of Shugan Tiaoshen (regulating liver and harmonizing spirit) intradermal needling protocol on the attentional networks of patients with subthreshold depression using the attention network test (ANT). METHODS: Eighty patients with subthreshold depression were randomly divided into an intradermal needling group (40 cases) and a sham needling group (40 cases, 2 cases dropped out), with an additional 43 healthy subjects as a normal group. The intradermal needling group received intradermal needling treatment, while the sham needling group received sham intradermal needling, with the needle tip not penetrating the skin. The bilateral Xinshu (BL 15), Ganshu (BL 18), Shentang (BL 44) as well as auricular points Xin (CO15) and Gan (CO12) were selected alternately. Treatments were administered twice a week for a total of 6 weeks in the two groups. The patient health questionnaire-9 (PHQ-9) and generalized anxiety disorder (GAD-7) scores were observed before treatment, after 3 weeks of treatment, after treatment, and at 1 month after the end of treatment (follow-up), and the ANT of the two groups of patients with subthreshold depression before and after treatment as well as the normal group of healthy subjects was compared. RESULTS: The PHQ-9 and GAD-7 scores of the patients with subthreshold depression were decreased after 3 weeks of treatment, after treatment, and in follow-up in the two groups (P<0.05), the differences in PHQ-9 and GAD-7 scores before and after treatment were greater in the intradermal needling group than those in the sham needling group (P<0.01). Before treatment, the executive control network reaction time of the subthreshold depression group (the intradermal needling group and the sham needling group) was higher than that of the normal group (P<0.05). Compared before treatment, the executive control network reaction time of the patients in the intradermal needling group and the sham needling group was decreased after treatment (P<0.05), and the alerting network reaction time of the intradermal needling group was increased after treatment (P<0.05); the difference in alerting network reaction time before and after treatment was greater in the intradermal needling group than that of the sham needling group (P<0.01). CONCLUSION: Regulating liver and harmonizing spirit intradermal needling protocol could effectively improve depressive and anxious symptoms in patients with subthreshold depression, and enhance the efficiency of the alerting network.

Immuno-modulatory role of baicalin in atherosclerosis prevention and treatment: current scenario and future directions.

Atherosclerosis (AS) is recognized as a chronic inflammatory condition characterized by the accumulation of lipids and inflammatory cells within the damaged walls of arterial vessels. It is a significant independent risk factor for ischemic cardiovascular disease, ischemic stroke, and peripheral arterial disease. Despite the availability of current treatments such as statins, proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors, and lifestyle modifications for prevention, AS remains a leading cause of morbidity and economic burden worldwide. Thus, there is a pressing need for the development of new supplementary and alternative therapies or medications. Huangqin (Scutellaria baicalensis Georgi. [SBG]), a traditional Chinese medicine, exerts a significant immunomodulatory effect in AS prevention and treatment, with baicalin being identified as one of the primary active ingredients of traditional Chinese medicine. Baicalin offers a broad spectrum of pharmacological activities, including the regulation of immune balance, antioxidant and anti-inflammatory effects, and improvement of lipid metabolism dysregulation. Consequently, it exerts beneficial effects in both AS onset and progression. This review provides an overview of the immunomodulatory properties and mechanisms by which baicalin aids in AS prevention and treatment, highlighting its potential as a clinical translational therapy.

Clinical implications of SOCS1 methylation in myelodysplastic syndrome.

The suppressor of cytokine signalling-1 (SOCS1) protein is a tumour suppressor. Hypermethylation of SOCS1 gene, resulting in transcriptional silencing, is suggested to play an important role in cancer development. We sought to characterise SOCS1 methylation in primary myelodysplastic syndrome (MDS) and clarify its clinical implications. The methylation status of SOCS1 was analysed by methylation-specific polymerase chain reaction in 114 patients with primary MDS and serial studies were performed in 29 of them. SOCS1 methylation occurred in 54 patients (47.4%), and was more frequent in patients with high-risk MDS than in those with low-risk (52.6% vs. 25.8%, P = 0.011). SOCS1 methylation was closely associated with NRAS mutation (P = 0.010) and inversely associated with good-risk karyotype (P = 0.021). With a median follow-up of 17 months (range: 1-231 months), two patients acquired SOCS1 methylation during disease progression. In two patients, SOCS1 methylation present at diagnosis, disappeared after haematopoietic stem cell transplantation. Patients with SOCS1 methylation had a higher cumulative risk of leukaemic transformation than those without (55.8% vs. 27.7% at 3 years, P = 0.004). This difference remained significant within the subgroup of patients with high-risk MDS (67.3% vs. 45.1% at 3 years, P = 0.045). This is the first report to demonstrate the clinical relevance of SOCS1 methylation in MDS. It may play an important role in the pathogenesis of MDS, especially among patients with high-risk subtypes.
