Objective:
To explore the latent profiles of psychological help seeking intentions among adolescents in Wuhan, and to investigate their association with non suicidal self injury (NSSI), in order to provide a theoretical basis for constructing an early intervention system for adolescents NSSI.
Methods:
From October to December 2022, a convenient sampling method was used to select 3 975 students from grades 7 to 12 in Wuhan. A self administered questionnaire assessed psychological help seeking intentions, followed by a post survey interview using the Ottawa Self injury Inventory to evaluate NSSI behaviors. Latent profile analysis(LPA) was used to explore the potential categories of help seeking intentions in adolescents. Multinomial Logistic regression was used to analyze factors associated with the latent profiles of help seeking intentions and multiple Logistic regression was used to analyze the association between latent profiles of help seeking intentions and NSSI.
Results:
Based on latent profile analysis, four latent profiles of help seeking intentions in adolescents were identified, namely overall low, moderate, and high help seeking group, as well as family/friendfocused help seeking group, accouting for 14.1%, 20.9%, 43.1% and 21.8%, respectively. Multinomial Logistic regression analysis showed that compared to senior high school students, junior high school students were more willing to seek help from family and friends ( OR =1.56); compared to males, females were more likely to exhibit moderate help seeking intentions( OR =1.37); students with extroverted or balanced personalities were more likely to exhibit high level help seeking intentions( OR =1.50, 1.49); students with average or good family economic status, better parental relationships, and adequate mental health knowledge were more likely to exhibit moderate and high level help seeking intentions( OR =1.59, 2.02; 1.80, 2.64; 1.44, 1.55; 1.34, 1.58) (all P <0.05). Students with moderate or severe family dysfunction were less likely to seek help from family and friends or to exhibit moderate and high level help seeking intentions( OR =0.51, 0.60, 0.25; 0.22, 0.27, 0.06, all P <0.01). Students whose parents exhibited stigma towards mental illness were less likely to show high level help seeking intentions( OR= 0.78 , P <0.05). Multivariable Logistic regression analysis results indicated that compared to the overall low help seeking intentions group, reduced risk of NSSI was observed among students in the overall moderate and overall high groups, as well as in the family/friend focused help seeking group( OR =0.73, 0.60, 0.70, all P <0.05).
Conclusions
Active psychological help seeking intentions can reduce NSSI behaviors in adolescents. Interventions should focus on improving family support environment to enhance adolescents intentions to seek psychological help.

Stroke is the leading cause of death and disability among adults in China, and its common complications include digestive system abnormalities, cognitive impairment, depression, stroke-associated pneumonia, and hemiplegia. The combination of traditional Chinese and Western medicine has great potential in treating post-stroke complications. Xinglou Chengqitang (XLCQT) is a representative prescription of alleviating the disease in the upper part by treating the lower part. It has definite therapeutic effect and high safety. Clinically, XLCQT is often used to treat stroke and its complications. However, the quantity and quality of clinical trials of XLCQT in treating post-stroke complications need to be improved. Additionally, since the basic research is weak, the material basis and multi-target mechanism for the efficacy of this prescription are unknown. This article reviews XLCQT in terms of the pharmacodynamic basis, medicinal properties, safety evaluation, and progress in clinical research and mechanisms in treating post-stroke complications. This article summarizes 22 key active ingredients of XLCQT in treating acute stroke complicated with syndrome of phlegm heat and fu-organ excess. Among these key active ingredients, resveratrol, kaempferol, luteolin, chrysoeriol, apigenin, (+)-catechin, and adenosine have good pharmacokinetic properties and high bioavailability. The mechanisms of XLCQT in treating post-stroke complications are complex, including inflammatory response, brain-gut axis, hypothalamic-pituitary-adrenal (HPA) axis, intestinal flora, neurotrophic factors, autophagy, oxidative stress, and free radical damage. This review helps to deeply understand the pharmacodynamic basis and mechanisms of XLCQT in treating post-stroke complications and provides a theoretical basis for the clinical application of XLCQT against post-stroke complications and the development of drugs.

Objective To understand the current status of low-density lipoprotein cholesterol (LDL-C) control in patients after coronary artery bypass grafting (CABG). Methods Clinical data of patients who underwent isolated CABG in Beijing Anzhen Hospital in 2023 were collected. All patients returned to our hospital approximately one year after surgery (10-13 months) for a lipid level recheck. We analyzed their LDL-C attainment status and influencing factors. Patients were categorized into two groups based on whether their LDL-C met the target: a LDL-C attainment group and a LDL-C non-attainment group. Results This study included 1456 patients who underwent CABG, including 320 females and 1136 males, with an average age of (61.41±9.12) years. One year post-surgery, 234 patients achieved the LDL-C target, with an attainment rate of 16.07%. The proportion of patients in the LDL-C attainment group who were ultra-high risk (77.35% vs. 92.06%, P<0.001), female (16.24% vs. 23.08%, P=0.021), and those with comorbid hypertension (55.98% vs. 63.18%, P=0.038) was significantly lower than those in the LDL-C non-attainment group. Additionally, the baseline body mass index (BMI) [(25.37±3.24) kg/m2 vs. (26.03±3.56) kg/m2, P=0.017], total cholesterol levels [(3.30±0.84) mmol/L vs. (4.01±1.03) mmol/L, P<0.001], LDL-C [(1.62±0.63) mmol/L vs. (2.25±0.85) mmol/L, P<0.001], and high-density lipoprotein cholesterol [(0.98±0.26) mmol/L vs. (1.02±0.24) mmol/L, P=0.049] upon admission in the attainment group were all lower than those in the non-attainment group. Moreover, the lipid-lowering drug usage rate in the attainment group (100.00% vs. 96.24%, P=0.003) and the proportion using two types of drugs together (25.21% vs. 10.72%, P<0.001) were both higher than those in the non-attainment group, while the statin monotherapy rate was lower than that in the non-attainment group (74.79% vs. 85.19%, P<0.001). Logistic regression analysis showed that baseline BMI (OR=0.928, P=0.012) and baseline LDL-C levels (OR=0.207, P<0.001), patient cardiovascular risk stratification (OR=0.155, P<0.001) and lipid-lowering drug treatment regimen (OR=3.758, P<0.001) are significant factors affecting the LDL-C control status. Conclusion The LDL-C compliance rate of patients undergoing CABG is at a relatively low level 1 year after surgery. Patients with very high risk of atherosclerotic cardiovascular disease, high baseline LDL-C levels, and overweight or obesity should be strengthened lipid management. For these patients, the intensity of lipid-lowering drug use or combination medication should be increased upon discharge.

ObjectiveTo investigate the effects of Qizhujianwei granules (QZJW) on abnormal proliferation and malignant transformation of gastric mucosal cells in rats with gastric intraepithelial neoplasia (GIN) and to explore the related mechanisms. MethodsA total of 80 SPF male Wistar rats were used. A GIN rat model was established using a four-factor comprehensive method consisting of methylnitronitrosoguanidine (MNNG), ranitidine, irregular feeding patterns, and sodium salicylate. Except for the normal group, after successful modeling, the rats were randomly divided according to body weight into a model group, a Moluodan group (0.55 g·kg-1), and a QZJW group (7.34 g·kg-1), with 12 rats in each group. All groups were treated for 8 weeks. The general characteristics of the rats and morphological changes of the gastric mucosa were observed. Histopathological changes of the gastric mucosa were examined by hematoxylin-eosin (HE) staining. Enzyme-linked immunosorbent assay (ELISA) was used to detect serum levels of pepsinogenⅠ (PGⅠ), pepsinogenⅡ (PGⅡ), and gastrin (G-17), as well as the expression level of transforming growth factor-β1 (TGF-β1) in gastric mucosal tissue, and the PGⅠ/PGⅡ ratio was calculated. Immunohistochemistry (IHC) was used to detect the localization and expression levels of proliferating cell nuclear antigen (Ki-67) and Vimentin in gastric mucosal tissue. Western blot analysis was used to determine the protein expression levels of Wnt family member 3A (Wnt3a), β-catenin, CyclinD1, proto-oncogene Cmyc, transforming growth factor-β receptor Ⅰ (TGFβRⅠ), intracellular signaling transducers Smad2/3, phosphorylated (p)-Smad2/3, twist family transcription factor (Twist1), and Vimentin in gastric mucosal tissue. ResultsCompared with the normal group, the model group showed characteristic changes including dim eyes, pale ears and claws, dark-red tongue, and reduced luster of the tail. The gastric mucosa appeared pale, with surface congestion and erosion. The gastric mucosal glands were disordered, the nuclear-to-cytoplasmic ratio increased, and local tumor cells were observed. Serum PGⅠ and PGⅡ levels and the PGⅠ/PGⅡ ratio were significantly decreased (P<0.01), while the level of G-17 was significantly increased (P<0.01). The protein expression levels of Ki-67, Wnt3a, β-catenin, CyclinD1, Cmyc, TGF-β1, TGFβRⅠ, Smad2/3, Twist1, and Vimentin in gastric mucosal tissue were significantly increased (P<0.05, P<0.01), whereas the ratio of p-Smad2/3 to Smad2/3 was significantly decreased (P<0.05). Compared with the model group, the general characteristics and gastric mucosal conditions of rats in the Moluodan group and the QZJW group were improved. HE staining showed that QZJW could effectively block the malignant progression of GIN. Serum PGⅠ and PGⅡ levels and the PGⅠ/PGⅡ ratio were significantly increased (P<0.05, P<0.01), while the level of G-17 was significantly decreased (P<0.01). The protein expression levels of Ki-67, Wnt3a, β-catenin, CyclinD1, Cmyc, TGF-β1, TGFβRⅠ, Smad2/3, Twist1, and Vimentin in gastric mucosal tissue were significantly decreased (P<0.05, P<0.01). ConclusionQZJW have a therapeutic effect on rats with GIN. The mechanism may involve inhibition of the Wnt/β-catenin signaling pathway to regulate the cell cycle and suppress abnormal cell proliferation. Meanwhile, it may inhibit epithelial-mesenchymal transition by suppressing the TGF-β1/Smad/Twist1 signaling pathway, thereby blocking the malignant progression of GIN.

ObjectiveTo reveal the active substances and mechanisms of modified Qing'e formula (MQEF) in delaying skin photoaging by ultra-performance liquid chromatography-quadrupole-time of flight mass spectrometry (UPLC-Q-TOF-MS),network pharmacology, and cell experiments. MethodsUPLC-Q-TOF-MS and a literature review were employed to analyze the transdermally absorbed components in mice after the topical application of MQEF. The potential targets of MQEF in treating skin photoaging were retrieved from databases.The compound-potential target network and protein-protein interaction network were constructed to screen the key components and core targets. A photoaging cell model was established by irradiating HaCaT cells with medium-wave ultraviolet B (UVB). The safe doses of bakuchiol (BAK) and salvianolic acid B (SAB) for treating HaCaT cells and the effects of BAK and SAB on the viability of cells exposed to UVB irradiation were determined by the cell counting kit-8 (CCK-8) method.The reactive oxygen species (ROS) fluorescent probe was used to measure the ROS production in the cells treated with BAK and SAB.The expression levels of genes related to oxidative stress,inflammation,collagen metabolism,and circadian rhythm clock were measured by Real-time PCR. ResultsA total of 24 transdermally absorbed components of MQEF were identified,which acted on 367 potential targets,and 417 targets related to skin photoaging were screened out,among which 47 common targets were predicted as the targets of MQEF in treating skin photoaging. MQEF exerted the anti-photoaging effect via key components such as BAK and SAB,which acted on core proteins such as serine/threonine kinase 1 (Akt1) and mitogen-activated protein kinase 3 (MAPK3) and intervened in core pathways such as the tumor necrosis factor (TNF) and phosphatidylinositol-3-kinase (PI3K)/protein kinase B (Akt) signaling pathways.Compared with the model group,the administration of BAK and SAB increased the survival rate of HaCaT cells (P<0.01),down-regulated the mRNA levels of cyclooxygenase-2 (COX-2),interleukin-6 (IL-6),tumor necrosis factor-α (TNF-α),matrix metalloproteinase-1 (MMP-1),and matrix metalloproteinase-9 (MMP-9) (P<0.01),and up-regulated the mRNA levels of heme oxygenase-1 (HO-1) and NAD(P)H quinone dehydrogenase 1 (NQO-1) (P<0.05,P<0.01) in photoaged HaCaT cells.In addition,it eliminated excess ROS production induced by UVB and up-regulated the mRNA levels of brain and muscle ARNT-like 1 (BMAL1) and circadian locomotor output cycles kaput (CLOCK) associated with circadian clock (P<0.05,P<0.01). ConclusionMQEF delays skin photoaging through the coordinated effects of various components,multiple targets,and diverse pathways.The key components BAK and SAB in MQEF exhibit anti-photoaging properties,which involve inhibiting oxidative stress,preventing collagen degradation,mitigating inflammation,and maintaining normal skin circadian rhythms by regulating clock gene expression.

ObjectiveTo investigate the effect and underlying mechanism of the Wulao Qisun prescription on pathological new bone formation in ankylosing spondylitis (AS). MethodsSynovial fibroblasts were isolated from the hip joints of AS patients and observed under a microscope to assess cell morphology. The cells were identified using immunofluorescence staining. The isolated AS fibroblasts were divided into blank group, low drug-containing serum group, medium drug-containing serum group, high drug-containing serum group, and positive drug group. After drug intervention, cell proliferation was measured using the cell counting kit-8 (CCK-8) assay to observe fibroblast growth and determine the optimal intervention time. Alkaline phosphatase (ALP) activity was measured using the alkaline phosphatase assay. Protein expression of osteocalcin (OCN), osteopontin (OPN), and runt-related transcription factor 2 (Runx2) was detected by Western blot. The mRNA expression levels of Wnt5a, β-catenin, and Dickkopf-1 (DKK-1) were measured by real-time quantitative polymerase chain reaction (Real-time PCR). ResultsCompared with the blank group, each drug-containing serum group of Wulao Qisun prescription and the positive drug group inhibited the proliferation of AS fibroblasts and reduced ALP expression (P<0.01). Compared with the blank group, the low drug-containing serum group of Wulao Qisun prescription downregulated β-catenin mRNA expression (P<0.05). The medium and high drug-containing serum groups and the positive drug group significantly downregulated Wnt5a and β-catenin mRNA expression (P<0.05, P<0.01), with the positive drug group showing the most pronounced effect (P<0.01). The high drug-containing serum group and the positive drug group significantly upregulated DKK-1 mRNA expression (P<0.01). Compared with the blank group, the low drug-containing serum group of Wulao Qisun prescription inhibited the expression of OPN and Runx2 proteins (P<0.05, P<0.01), while the medium and high drug-containing serum groups and the positive drug group inhibited the expression of OCN, OPN, and Runx2 proteins (P<0.05, P<0.01). ConclusionThe Wulao Qisun prescription can inhibit the proliferation and osteogenic differentiation of AS fibroblasts, thereby delaying the formation of pathological new bone in AS. The possible mechanism involves the regulation of Wnt/β-catenin-related gene expression, further inhibiting the transcription of downstream target genes.

Lipid turbidity disease is a metabolic disease featuring lipid metabolism disorders caused by many factors such as social environment, diet, and lifestyle, which is closely related to many diseases in modern medicine, such as hyperlipidemia, obesity, fatty liver, atherosclerosis, metabolic syndrome, and cardiovascular and cerebrovascular diseases, with a wide range of influence and far-reaching harm. According to the Huangdi Neijing, lipid turbidity disease reflects the pathological change of the body's physiologic grease. Grease is the thick part of body fluids, which has the function of nourishing, and it is the initial state and source of important substances in the human body such as brain, marrow, essence, and blood. Once the grease of the human body is abnormal, it can lead to lipid turbidity disease. The Huangdi Neijing also points out the physiological relationship between the transportation and transformation of body fluids and the rise and fall of the spleen and stomach, which can deduce the pathological relationship between the occurrence of lipid turbidity disease and the abnormal rise and fall of the spleen and stomach functions. Lipid turbidity disease is caused by overconsumption of fatty and sweet foods or insufficient spleen and stomach endowments, leading to disorders of the function of promoting clear and reducing turbidity in the spleen and stomach. This leads to the transformation of thick grease in body fluids into lipid turbidity, which accumulates in the body's meridians, blood vessels, skin pores, and organs, forming various forms of metabolic diseases. The research team believed that the pathological basis of lipid turbidity disease was the abnormal rise and fall of the spleen and stomach and the obstruction of the transfer of grease. According to the different locations where lipid turbidity stays, it was divided into four common pathogenesis types: ''inability to distinguish between the clear and turbid, turbid stagnation in the Ying blood'', ''spleen not rising clear, turbid accumulation in the vessels'', ''spleen dysfunction, lipid retention in the pores'', ''spleen failure to transportation and transformation, and grease accumulation in the liver''. According to the pathogenesis, it could be divided into four common syndromes, namely, turbid stagnation in the Ying blood, turbid accumulation in the vessels, lipid retention in the pores, and grease accumulation in the liver, and the corresponding prescriptions were given for syndrome differentiation and treatment, so as to guide clinical differentiation and treatment of the lipid turbidity disease.

BACKGROUND:The repair process of myocardial injury involves complex cellular and molecular mechanisms,especially mitochondrial calcium homeostasis,macrophage autophagy and pyroptosis pathways.Traditional Chinese medicine(TCM)has shown significant clinical efficacy in improving myocardial injury,but its mechanism of action needs to be thoroughly investigated. OBJECTIVE:To investigate the role of mitochondrial calcium homeostasis-mediated macrophage autophagy and pyroptosis pathways in myocardial injury,and to summarize the progress of TCM in this field. METHODS:A computerized search was performed for relevant literature from the database inception to March 2024 in the Web of Science,PubMed and CNKI.The search terms were"mitochondrial calcium homeostasis,macrophage autophagy,macrophage pyroptosis,traditional Chinese medicine,myocardial injury,myocardial injury reperfusion"in Chinese and English.Through literature review,we analyzed the relationship between mitochondrial calcium homeostasis and macrophage autophagy and pyroptosis,explored the mechanism of their roles in myocardial injury,and summarized the pathways of multi-targeted,multi-pathway effects of TCM. RESULTS AND CONCLUSION:The maintenance of mitochondrial calcium homeostasis has been found to be closely related to the normal function of cardiomyocytes.Macrophages can participate in the repair process of myocardial injury through autophagy and pyroptosis pathways.Autophagy contributes to cell clearance and regulation of inflammatory response,while pyroptosis affects myocardial repair by releasing inflammatory factors.TCM regulates mitochondrial calcium homeostasis and macrophage function through multiple mechanisms.For example,astragalosid regulates calcium homeostasis by lowering mitochondrial membrane potential and inhibiting cytochrome C,and epimedium glycoside plays a role in reducing β-amyloid deposition.In addition,herbal compounds and single drugs promote myocardial repair by activating or inhibiting specific signaling pathways,such as PI3K/AKT and nuclear factor-κB signaling pathways.Future studies should focus on the interactions between mitochondrial calcium homeostasis,autophagy and pyroptosis pathways,as well as how TCM can exert therapeutic effects through these pathways to provide new strategies and drugs for the treatment of myocardial injury.

Objective:
To determine the clinical efficacy and mechanism of Piwei Peiyuan Pill (PPP) combined with moxibustion for treating patients with chronic atrophic gastritis (CAG) with spleen and stomach weakness syndrome.
Methods:
Ninety-six CAG patients with spleen and stomach weakness syndrome who met the inclusion and exclusion criteria were enrolled at the Department of Spleen and Stomach Diseases of the Second Affiliated Hospital of Anhui University of Chinese Medicine from June 2022 to December 2023. The patients were randomly divided into a control, a Chinese medicine, and a combined group using a random number table method, with 32 cases in each group (two cases per group were excluded). The control group was treated with rabeprazole combined with folic acid tablets (both thrice daily), the Chinese medicine group was treated with PPP (8 g, thrice daily), and the combined group was treated with moxa stick moxibustion (once daily) on the basis of the Chinese medicine group for 12 consecutive weeks. Gastric mucosa atrophy in the three groups was observed before and after treatment. The gastric mucosal pathological score was evaluated. The Patient Reported Outcome (PRO) scale was used to evaluate the patients′ physical and mental health status and quality of life.An enzyme-linked immunosorbent assay was used to detect serum tumor necrosis factor (TNF)-α, interleukin (IL)-1β, IL-4, IL-10, IL-37, and transforming growth factor (TGF)-β levels in each group. Real-time fluorescence PCR was used to detect the relative expression levels of signal transducer and activator of transcription 3 (STAT3) and mammalian target of rapamycin (mTOR) mRNA in each group. Western blotting was used to detect the relative expression levels of proteins related to the STAT3/mTOR signaling pathway, and the adverse drug reactions and events were recorded and compared.
Results:
There was no statistical difference in age, gender, disease duration, family history of gastrointestinal tumors, alcohol consumption history, and body mass index among the three groups of patients.The total therapeutic efficacy rates of the control, Chinese medicine, and combined groups in treating gastric mucosal atrophy were 66.67% (20/30), 86.67% (26/30), and 90.00% (27/30), respectively (P<0.05). Compared to before treatment, the pathological and PRO scale scores of gastric mucosa in each group decreased after treatment, and TNF-α, IL-1β, IL-37, and TGF-β levels decreased. The relative STAT3 and mTOR mRNA expression levels, as well as the relative STAT3, p-STAT3, mTOR, and p-mTOR protein expression levels decreased (P<0.05), whereas the IL-4 and IL-10 levels increased (P<0.05). After treatment, compared to the control group, the pathological score of gastric mucosa, PRO scale score, TNF-α, IL-1β, IL-37, TGF-β content, relative STAT3 and mTOR mRNA expression levels, and relative STAT3, p-STAT3, mTOR, and p-mTOR protein expression levels in the Chinese medicine and combined groups after treatment were reduced (P<0.05), whereas the IL-4 and IL-10 levels increased (P<0.05). After treatment, compared to the Chinese medicine group, the combined group showed a decrease in relative STAT3, mTOR mRNA expression levels, and STAT3, p-STAT3, mTOR, and p-mTOR protein expression levels (P<0.05).
Conclusion
The combination of PPP and moxibustion may regulate the inflammatory mechanism of the body by inhibiting the abnormal activation of the STAT3/mTOR signaling pathway, upregulating related anti-inflammatory factor levels, downregulating pro-inflammatory factor expression, and increasing related repair factor expression, thereby promoting the recovery of atrophic gastric mucosa, reducing discomfort symptoms, and improving the physical and mental state of CAG patients with spleen and stomach weakness syndrome.
