Sleep, skin, and health are closely interconnected. Clinically, insomnia has a high incidence and is often accompanied by or secondary to skin aging. The two conditions exhibit "different diseases with the same syndrome", significantly affecting the physical and mental health of the Chinese population. Preventing and treating skin aging by improving insomnia is an important strategy, with the principle of "treating different diseases with the same approach" serving as a crucial therapeutic guideline. However, effective clinical prevention and treatment methods for both conditions remain lacking. Traditional Chinese medicine (TCM) has a profound theoretical foundation and notable efficacy in the concurrent treatment of insomnia and skin aging, yet there are few reports on the etiology, pathogenesis, therapeutic principles, and treatment methods of their shared treatment, warranting further exploration. Based on holistic view and syndrome differentiation and treatment in TCM, this study systematically investigates the theoretical origins of the shared manifestations of insomnia and skin aging from multiple dimensions, including etiology, pathological location, pathogenesis, disease nature, and prevention and treatment strategies. As early as Huangdi's Internal Classic (Huangdi Neijing), it was recognized that mental clarity during the day, sound sleep at night, and firm, healthy skin are key indicators of external health, whereas daytime lethargy, poor sleep quality, and dry, withered skin are prominent signs of aging. Maintaining mental clarity during the day and restful sleep at night is essential for skin integrity and healthy aging. Later medical scholars proposed that the common etiology of insomnia and skin aging lies in "internal-external interactions", with the pathological location involving "the five organ systems". The primary pathogenesis includes "deficiency, fire, stagnation, phlegm, and blood stasis", while the disease nature is often characterized by "a combination of deficiency and excess". Treatment should be guided by syndrome differentiation, following the principle of balancing Yin and Yang. This theoretical exploration enriches and advances TCM understanding of disease onset and prevention, providing theoretical guidance for the clinical prevention and treatment of insomnia-associated skin aging and contributing to the realization of the "Healthy China" initiative.

BackgroundCognitive function is closely related to an individual's quality of life and social functioning, with approximately 20%~35% of patients with depressive disorder experiencing some degree of cognitive impairment even after clinical symptom remission. Existing evidence suggests that tACS can improve specific cognitive domains, such as memory function, while its effects on other cognitive dimensions, such as executive functioning, attention, and information processing speed, remain unclear. ObjectiveTo explore the effects of tACS on the multidimensional cognitive functions and emotional problems of patients with depressive disorder, thus to provide references for the treatment of depressive disorder. MethodsForty-nine patients with depressive disorder who were hospitalized in the Fourth People's Hospital of Wuhu from November 2022 to October 2024 and met the diagnostic criteria for depressive disorder outlined in the Diagnostic and Statistical Manual of Mental Disorders, fifth edition (DSM-5), were selected as study participants. Subjects were randomly divided into study group (n=23) and control group (n=26) based on Microsoft Excel. Both groups received sertraline treatment. The initial dose was 50 mg/day, which gradually titrated upward based on individual variability, drug tolerance, and therapeutic response, with a maintenance dose ranging from 100 to 200 mg/day. In addition, the study group underwent tACS therapy for 4 weeks, with 5 sessions per week, each lasting 20 minutes. The control group received sham stimulation, in which the stimulus was interrupted after the first 30 seconds. At baseline, the 4th week, and the 12th week of treatment, patients were assessed using the Hamilton Depression Scale-17 item (HAMD-17), Hamilton Anxiety Scale (HAMA), and MATRICS Consensus Cognitive Battery (MCCB). ResultsRepeated measures analysis of variance indicated that both the time effect and the time×group interaction effect for HAMD-17 scores were statistically significant between the two groups (F=260.437, 25.309, P<0.01). At week 12 of treatment, the HAMD-17 score in the study group was lower than that in the control group (t=4.236, P<0.01). For HAMA scores, the time effect, group effect, and time×group interaction effect were all statistically significant between the two groups (F=248.082, 4.506, 9.500, P<0.05 or 0.01). At weeks 4 and 12, study group reported lower HAMA scores compared with control group (t=4.580, 2.608, P<0.05 or 0.01). Regarding the MCCB scores for attention/vigilance, verbal learning, and overall composite, the time effect, group effect, and time×group interaction effect were all statistically significant between the two groups (F=70.331, 27.882, 51.679, 5.560, 10.948, 7.860, 8.490, 3.874, 5.025, P<0.05 or 0.01). After intervention, the study group showed significantly higher MCCB scores for attention/vigilance, verbal learning, and overall composite at both week 4 (t=-2.149, -3.530, -2.740, P<0.05) and week 12 (t=-3.534, -3.576, -3.838, P<0.01) when compared to the control group. ConclusionThe combined tACS and sertraline therapy may demonstrate superior efficacy to pharmacotherapy alone in the short term for improving attention/vigilance, verbal learning, overall cognitive function, and anxiety symptoms in patients with depressive disorders. Based on the 12-week outcomes, the combined tACS and sertraline therapy not only sustaine its previously observed advantages in improving cognitive domains and anxiety symptoms, but also demonstrate potentially superior efficacy over monotherapy in alleviating depressive symptoms.

ObjectiveTo observe the effects of Hedysari Radix polysaccharide on the apoptosis of gastric sinus smooth muscle cells and explore the underlying mechanism via the insulin-like growth factor-1 (IGF-1)/phosphatidylinositol 3-kinase (PI3K)/serine-threonine kinase (Akt) pathway in the rat model of diabetic gastroparesis (DGP). MethodSixty-two Wistar male rats were randomized into a blank group (n=12) and a modelling group (n=50). The rat model of DGP was established by small-dose multiple intraperitoneal injections of streptozotocin combined with an irregular high-fat and high-sugar diet for 4 weeks. The modeled rats were randomized into model group, mosapride citrate (1.35 mg·kg-1), and high-, medium-, and low-dose (200, 100, and 50 mg·kg-1, respectively) Hedysari Radix polysaccharide groups. The rats were administrated with corresponding drugs by gavage, and those in the blank and model groups with equal volumes of pure water by gavage once a day for 8 consecutive weeks. The random blood glucose and body mass were measured every 2 weeks, and gastric emptying rate was calculated. Hematoxylin-eosin (HE) staining was used to observe the pathological changes of smooth muscle in gastric antrum, and terminal deoxynucleoitidyl transferase-mediated nick-end labeling (TUNEL) was employed to detect the apoptosis of smooth muscle cells in the gastric antrum. The expression of IGF-1, phosphorylated (p)-PI3K, and p-Akt in the smooth muscle of gastric sinus tissue was detected by immunohistochemistry. Western blot was employed to determine the protein levels of IGF-1, p-PI3K/PI3K, p-Akt/Akt, B-cell lymphoma-2 (Bcl-2), and Bcl-2-associated X protein (Bax) in the smooth muscle of the gastric antrum. ResultCompared with the blank group, the model group showed elevated random blood glucose at all time points (P<0.01), decreased body mass and gastric emptying rate (P<0.01), increased apoptotic index of smooth muscle cells in the gastric antrum (P<0.01), down-regulated protein levels of IGF-1, p-PI3K/PI3K, p-Akt/Akt, and Bcl-2, and up-regulated protein level of Bax (P<0.01). Compared with the model group, the 8 weeks of drug administration lowered the random blood glucose, increased the body mass and gastric emptying rate (P<0.05, P<0.01), decreased the apoptotic index of smooth muscle cells in the gastric antrum (P<0.05, P<0.01), up-regulated the protein levels of IGF-1, p-PI3K/PI3K, p-Akt/Akt, and Bcl-2, and down-regulated the protein level of Bax (P<0.05, P<0.01). Compared with the mosapride citrate group,the administration of low-dose Hedysari Radix polysaccharide for 6 and 8 weeks lowered the random blood glucose and decreased the body mass (P<0.05, P<0.01),low and medium-dose Hedysari Radix polysaccharide decreased the gastric emptying rate and the apoptotic index of smooth muscle cells in the astragaloside low-dose group decreased (P<0.05). The protein levels of IGF-1,p-PI3K/PI3K,p-Akt/Akt and Bcl-2(low dose)were down-regulated and the protein level of Bax was up-regulated by low doses of Hedysari Radix polysaccharide (P<0.05, P<0.01). Compared with high-dose Hedysari Radix polysaccharide, low-dose Hedysari Radix polysaccharide elevated random blood glucose and reduced body mass after 6 and 8 weeks of administration (P<0.05, P<0.01), and the low and medium doses decreased the gastric emptying rate, increased the apoptotic index of smooth muscle cells in the gastric antrum (P<0.05, P<0.01), down-regulated the protein levels of IGF-1, p-PI3K/PI3K, p-Akt/Akt, and Bcl-2, and up-regulated the protein level of Bax (P<0.05, P<0.01). Compared with the medium-dose group,the low-dose group of Hedysari Radix polysaccharide had lower body mass,lower gastric emptying rate in rats,higher apoptotic index of smooth muscle cells in gastric sinus tissue after 6 and 8 weeks of administration (P<0.05, P<0.01), and lower protein expression of IGF-1,p-PI3K/PI3K,p-Akt/Akt. ConclusionHedysari Radix polysaccharide protects the smooth muscle cells in gastric antrum against apoptotic injury and promotes gastric motility by activating the IGF-1/PI3K/Akt signaling pathway, as manifested by the up-regulated expression of IGF-1, p-PI3K, p-Akt, and Bcl-2 and down-regulated expression of Bax.

Tumor cells use glycolysis to provide material and energy under hypoxic conditions to meet the energy requirements for rapid growth and proliferation, namely the Warburg effect. Even under aerobic conditions, tumor cells mainly rely on glycolysis to provide energy. Therefore, glucose transporter protein 1(GLUT1), which is involved in the process of glucose metabolism, plays an important role in tumorigenesis, development and drug resistance, and is considered to be one of the important targets in the treatment of malignant tumors. In recent years, research on tumor glucose metabolism has gradually become a hot spot. It has been shown that various factors are involved in the regulation of tumor energy metabolism, among which the role of GLUT1 is the most critical. In this paper, the authors reviewed the latest research progress of GLUT1-targeted traditional Chinese medicine(TCM) active ingredient nano-delivery system in tumor therapy, aiming to reveal the feasibility and effectiveness of this system in the delivery of chemotherapeutic drugs. The GLUT1-targeted TCM active ingredient nano-delivery system can overcome the bottleneck of the traditional targeting strategy as well as the high-permeability long retention(EPR) effect. In summary, the authors believe that the GLUT1-targeted TCM active ingredient nano-delivery system provides a new strategy for targeted treatment of tumors and has a broad application prospect in tumor prevention and treatment.

ObjectiveSerum metabolomics of acute lung injury(ALI) in rats was conducted using ultra-performance liquid chromatography-quadrupole-time-of-flight mass spectrometry(UPLC-Q-TOF-MS) to explore the similarities and differences in the mechanism of Qingqiao(harvested when the fruits of Forsythiae Fructus were initially ripe and still green in color) and Laoqiao(harvested when the fruits of Forsythiae Fructus were ripe) in the treatment of ALI. MethodA total of 24 SD male rats were acclimatized and fed for 1 week, 6 of them were randomly selected for the blank group and 18 for the experimental group. The ALI model was induced in the experimental group by tracheal intubation with lipopolysaccharide(LPS). After successfully constructing the ALI model, these rats was randomly divided into model group, Qingqiao group and Laoqiao group, with 6 rats in each group. The Qingqiao and Laoqiao groups were administered orally once a day at a dose of 1.5 g·kg-1, while the blank and model groups received an equivalent volume of saline for 3 consecutive days. The pathological conditions of rat lung tissues were comprehensively assessed by hematoxylin-eosin(HE) staining, wet-to-dry mass ratio(W/D) of lung tissues, and protein concentration in rat bronchoalveolar lavage fluid(BALF). The levels of interleukin(IL)-6, IL-1β and tumor necrosis factor(TNF)-α in BALF were quantified using enzyme-linked immunosorbent assay(ELISA). UPLC-Q-TOF-MS was used to identify and analyze the chemical compositions of Qingqiao and Laoqiao, and serum metabolomics of rats in each group was analyzed, combined with multivariate statistical analysis with variable importance in the projection(VIP) value>1, P<0.05 from t-test, and fold change(FC)≥1.5 or FC≤0.5 to screen the differential metabolites Qingqiao and Laoqiao for the treatment of ALI. The Kyoto Encyclopedia of Genes and Genomes(KEGG) database was used in combination with MetaboAnalyst for the metabolic pathway analysis of the screened differential metabolites. ResultCompared with the blank group, rats in the model group exhibited enlarged alveolar lumen, ruptured alveoli, interstitial hemorrhage, bronchial exudation of a large number of neutrophils and erythrocytes, and a significant increase in the protein concentration in the BALF and the W/D value of the lung tissues(P<0.01). In contrast, compared with the model group, rats in the Qingqiao group and the Laoqiao group showed reduced bronchial hemorrhage in the lungs, and the protein concentration in the BALF and the W/D value of the lung tissues were significantly decreased(P<0.01), the lung injury was significantly alleviated, but more obvious in the Qingqiao group. Compared with the blank group, the expression levels of IL-6, IL-1β and TNF-α in the BALF of the model group were significantly higher(P<0.01). Additionally, compared with the model group, the expression levels of IL-6, IL-1β and TNF-α in the Qingqiao and Laoqiao groups were significantly lower(P<0.01). The chemical composition analysis of Qingqiao and Laoqiao revealed that 63 components were detected in Qingqiao and 55 components were detected in Laoqiao, with 47 common components, 16 components unique to Qingqiao and 8 components unique to Laoqiao. Characterizing the differences in serum metabolomics in rats, 19 and 12 metabolites were called back by Qingqiao and Laoqiao, respectively. The metabolic pathway enrichment analysis showed that Qingqiao exerted its therapeutic effects by affecting 6 key metabolic pathways, including linoleic acid metabolism, phenylalanine metabolism, phenylalanine, tyrosine and tryptophan biosynthesis, glycerophospholipid metabolism, α-linolenic acid metabolism, and arachidonic acid metabolism, and Laoqiao exerted therapeutic effects by affecting 6 key metabolic pathways, including linoleic acid metabolism, arachidonic acid metabolism, sphingolipid metabolism, phenylalanine metabolism, ascorbate and aldarate metabolism, and glycerophospholipid metabolism. ConclusionQingqiao and Laoqiao have therapeutic effects on ALI, and Qingqiao is more effective. Both of them can play a therapeutic role in ALI by regulating amino acid metabolism and lipid metabolism, but the metabolic pathways affected by them are different.

Depression is a prevalent mental illness worldwide, its multifaceted pathogenesis is still in the exploratory stage. MicroRNA (miRNA), as a crucial epigenetic regulator, plays an important role in depression. miR-124 is one of the most abundant miRNAs in the central nervous system including neurons and microglia, and involved in various biological events like neuron development and differentiation, synaptic and axonal growth, neural plasticity, inflammation and autophagy. Recent studies have reported abnormal expression of miR-124 in both depression patients and animal models. Most of the studies showed that miR-124 is upregulated in the hippocampus or prefrontal cortex in stress-induced rodent depression animal models such as CUMS, CSDS, CORT, CRS and LH but some evidence for divergence. Upregulation of miR-124 expression may be involved in depression-like behavior via CREB/BDNF/TrkB pathway, GR pathway, SIRT1 pathway, apoptosis and autophagy pathways by directly targeting these genes including Creb, Bdnf, Sirt1, Nr3c1, Ezh2 and Stat3. The downregulation of miR-124 expression in neurons is mainly involved in the neurogenesis and neuroplasticity impairments in depression by targeting the Notch signaling pathway and DDIT4/TSC1/2/mTORC1 pathway. The downregulation of miR-124 expression also was found in the activated microglia in the stress-induced models, and resulted in neuroinflammation. In summary, the abnormal expression of miR-124 in the brain of depression-related models and its related mechanisms are complex and even contradictory, and still need further research. This review provides a summary of the research progress of miR-124 in depression.

Objective:To investigate the current status of endoscopic treatment for gastroesophageal varices in portal hypertension in China, and to provide supporting data and reference for the development of endoscopic treatment.Methods:In this study, initiated by the Liver Health Consortium in China (CHESS), a questionnaire was designed and distributed online to investigate the basic condition of endoscopic treatment for gastroesophageal varices in portal hypertension in 2022 in China. Questions included annual number and indication of endoscopic procedures, adherence to guideline for preventing esophagogastric variceal bleeding (EGVB), management and timing of emergent EGVB, management of gastric and isolated varices, and improvement of endoscopic treatment. Proportions of hospitals concerning therapeutic choices to all participant hospitals were calculated. Guideline adherence between secondary and tertiary hospitals were compared by using Chi-square test.Results:A total of 836 hospitals from 31 provinces (anotomous regions and municipalities) participated in the survey. According to the survey, the control of acute EGVB (49.3%, 412/836) and the prevention of recurrent bleeding (38.3%, 320/836) were major indications of endoscopic treatment. For primary [non-selective β-blocker (NSBB) or endoscopic therapies] and secondary prophylaxis (NSBB and endoscopic therapies) of EGVB, adherence to domestic guideline was 72.5% (606/836) and 39.2% (328/836), respectively. There were significant differences in the adherence between secondary and tertiary hospitals in primary prophylaxis of EGVB [71.0% (495/697) VS 79.9% (111/139), χ2=4.11, P=0.033] and secondary prophylaxis of EGVB [41.6% (290/697) VS 27.3% (38/139), χ2=9.31, P=0.002]. A total of 78.2% (654/836) hospitals preferred endoscopic therapies treating acute EGVB, and endoscopic therapy was more likely to be the first choice for treating acute EGVB in tertiary hospitals (82.6%, 576/697) than secondary hospitals [56.1% (78/139), χ2=46.33, P<0.001]. The optimal timing was usually within 12 hours (48.5%, 317/654) and 12-24 hours (36.9%, 241/654) after the bleeding. Regarding the management of gastroesophageal varices type 2 and isolated gastric varices type 1, most hospitals used cyanoacrylate injection in combination with sclerotherapy [48.2% (403/836) and 29.9% (250/836), respectively], but substantial proportions of hospitals preferred clip-assisted therapies [12.4% (104/836) and 26.4% (221/836), respectively]. Improving the skills of endoscopic doctors (84.2%, 704/836), and enhancing the precision of pre-procedure evaluation and quality of multidisciplinary team (78.9%, 660/836) were considered urgent needs in the development of endoscopic treatment. Conclusion:A variety of endoscopic treatments for gastroesophageal varices in portal hypertension are implemented nationwide. Participant hospitals are active to perform emergent endoscopy for acute EGVB, but are inadequate in following recommendations regarding primary and secondary prophylaxis of EGVB. Moreover, the selection of endoscopic procedures for gastric varices differs greatly among hospitals.
