Objective: To investigate the sleep quality in patients with burning mouth syndrome (BMS) and its influencing factors, providing a basis for developing sleep intervention measures to reduce the impact of BMS symptoms. Methods: This study was reviewed and approved by the Medical Ethics Committee, and informed consent was obtained from patients. A total of 150 patients with BMS and 150 healthy volunteers were enrolled as subjects in this study. The Pittsburgh sleep quality index (PSQI) was used to assess the sleep quality of patients with BMS. Visual analog scale (VAS) was used to assess the degree of oral mucosal pain, generalized anxiety disorder 7-item scale (GAD-7) was used to assess the frequency of anxiety symptoms, and the patient health questionnaire depression questionnaire (PHQ-9) was used to assess the frequency of depression symptoms. Univariate analysis was performed to identify potential influencing factors affecting sleep quality in patients with BMS, and multiple linear regression analysis was employed to determine independent risk factors. Results: The PSQI score for patients with BMS was 7.61 ± 4.29, which was significantly higher than that of healthy controls (P = 0.016). In the PSQI subscale analysis, patients with BMS exhibited increased sleep latency, decreased sleep duration, and lower sleep efficiency compared to healthy controls (P<0.05). Patients with BMS and comorbid sleep difficulties had significantly higher scores on GAD-7 and PHQ-9 compared to the patients with BMS without sleep difficulties (P<0.001), but there was no significant difference in pain VAS scores between the two (P = 0.068). Multiple linear regression analysis revealed that longer disease duration (>6 months), the presence of systemic concomitant symptoms (such as headache and mental stress), and higher depression scores were identified as independent risk factors affecting sleep quality in patients with BMS. Conclusion For patients with BMS, long course of illness, presence of headaches, high mental stress, and depressive symptoms may be independent factors affecting their sleep quality.

Tumorigenesis， invasion， and metastasis occur in the context of a persistent inflammatory microenvironment， and a variety of inflammatory factors can lead to the development of various tumors. Guided by the thought of "preventive treatment of disease" in TCM and the concept of tertiary prevention in modern medicine， it is of great significance to effectively intervene in the inflammatory stage of the disease， interrupt disease progression， prevent the occurrence of malignant tumors， and reverse the process of "inflammation-to-cancer transformation". Sinisan， a commonly used prescription in the Treatise on Febrile Diseases， has been widely applied in the treatment of precancerous lesions of the digestive system， demonstrating considerable advantages. This article reviewed literature from the past 20 years， summarizing the application of Sinisan in precancerous lesions of the digestive system from three aspects： the exploration of its prescription-syndrome relationship， clinical application， and mechanistic study. It is found that basic syndrome indications of Sinisan include harmonizing the Earth element to promote spleen-stomach transportation and transformation， soothing the liver and nourishing the Wood element to restore the smooth flow of Qi， and regulating Yin and Yang to relieve stagnation within the system. In clinical application， Sinisan has shown significant efficacy in atrophic gastritis and precancerous conditions such as intestinal metaplasia， gastric ulcer， ulcerative colitis， esophagitis， and pancreatitis. Mechanistic studies have revealed that Sinisan can inhibit inflammatory factors and improve the inflammatory microenvironment， inhibit cell proliferation and regulate apoptosis， exhibit anti-angiogenic and antitumorigenic effects， modulate immune function， and exert antioxidant effects. These mechanisms can be achieved by regulating pathways such as nuclear factor erythroid 2-related factor 2/heme oxygenase-1 （Nrf2/HO-1）， farnesoid X receptor （FXR）/Nrf2， phosphatidylinositol 3-kinase/protein kinase B （PI3K/Akt）， Takeda G protein-coupled receptor 5/cyclic adenosine monophosphate/protein kinase A （TGR5/cAMP/PKA）， interleukin-4/signal transducer and activator of transcription 6 （IL-4/STAT6）， Janus kinase/signal transducer and activator of transcription （JAK/STAT）， RhoA/Rho-associated protein kinase （RhoA/ROCK）， and transforming growth factor-β/Smad proteins （TGF-β/Smads）， confirming Sinisan's role in reversing the inflammation-to-cancer transformation. The current research status of Sinisan in precancerous lesions of the digestive system was thoroughly examined through the above three aspects， along with the identification of limitations and areas for improvement in current research. The aim is to provide a basis and support for future in-depth research on Sinisan， promote the development of new integrated treatment models combining TCM and Western medicine for precancerous lesions， and aid in the research and development of drugs related to precancerous lesions.

The curative and markedly effective rate of TCM syndrome in the treatment group was 53.05% （148/279）， which was significantly higher than 25.27% （23/91） in the control group （P＜0.01）. After treatment， scores of the number as well as duration of angina attacks and pain severity， the total score of angina symptoms， and the usage of nitroglycerin significantly decreased in both groups， and more changes were seen in the treatment group than in the control group； the scores of physical limitations， anginal stability， anginal frequency， treatment satisfaction， and disease perception in both groups significantly increased， and more improvement were shown in the experimental group regarding the anginal stability， anginal frequency and treatment satisfaction （P＜0.05 or P＜0.01）. The effects of chest pain， chest tightness， palpitation， shortness of breath and fatigue in experimental group were significantly higher than those in control group （P＜0.05 or P＜0.01）. There was no significant difference in the exercise duration of treadmill test and Duke score among patients between the two groups either before or after treatment （P＞0.05）. Adverse events occurred in 66 cases （23.66%） of the experimental group and 16 cases （17.58%） of the control group， with no statistical significance between the two groups （P＞0.05）. ConclusionThe Uyghur medicine YDMHP can effectively improve symptoms of angina pectoris， reduce the number， duration， and intensity of attacks， decrease the dosage of nitrogly-cerin and improve the individual TCM symptoms and has good safety in the treatment of SAP patients of qi stagnation and blood stasis.

Objective To evaluate the therapeutic effect of evodiamine(Evo)on atopic dermatitis(AD)in rat models by regulating the cyclic adenosine monophosphate(cAMP)/protein kinase A(PKA)/cAMP response ele-ment binding protein(CREB)signaling pathway.Methods A rat model of AD was established by administration of multiple doses of 2,4-dinitrochlorobenzene(DNCB).The animals were randomly divided into AD group,Evo-low-dose(Evo-L,5 mg/kg)group,Evo-high-dose(Evo-H,10 mg/kg)group,Evo-H+H-89(5 mg/kg)group and dexamethasone(0.1 mg/kg)group.Normal rats were used as the control group and then the degree of skin damage of rats in each group was scored.Abdominal blood was taken to detect the levels of interleukin-4(IL-4),cAMP,and tumor necrosis factor-α(TNF-α)in serum;Skin lesion tissue was collected to detect pathological change,counting of mast cells,PKA/CREB related protein expression and expression of IL-4 and TNF-α mRNA in the tissue.Results Compared with control group,the level of cAMP in serum,the expression of p-PKA/PKA,and p-CREB/CREB in skin lesions of AD group were reduced,the severity score of skin lesions,level of IL-4 and TNF-α,epidermal thickness,number of mast cells and mRNA expression of IL-4 and TNF-α in skin lesion tissues were all significantly increased(P＜0.05).Compared with AD group,the level of cAMP in serum,the expression of p-PKA/PKA,and p-CREB/CREB in skin lesions in Evo-L group,Evo-H group,and dexamethasone group were increased,the severity score of skin lesions,level of IL-4 and TNF-α,epidermal thickness,number of mast cells,and mRNA expression of IL-4 and TNF-α in skin lesion tissues all reduced(P＜0.05).Compared with the Evo-H group,the level of cAMP in serum,the expression of p-PKA/PKA,and p-CREB/CREB in skin lesions in Evo-H+H-89 group was reduced and the severity score of skin lesion,level of IL-4 and TNF-α,epidermal thickness,num-ber of mast cells,and mRNA expression of IL-4 and TNF-α in skin lesion tissues significantly increased(P＜0.05).Conclusions Evo inhibits inflammatory response and pathological damage through regulation of cAMP/PKA/CREB signaling pathway in AD rat models.

Objective To investigate the expression and mechanism of long non-coding RNA (lncRNA) GHRLOS2 in colorectal cancer tissues and cells. Methods Real-time quantitative reverse transcription polymerase chain reaction (qRT-PCR) was used to detect the expression levels of GHRLOS2 and microRNA-33b-5p (miR-33b-5p) in colorectal cancer tissues or cells. Overexpressing of GHRLOS2 in HCT116 and SW480 colorectal cancer cell lines were constructed, and the effects of overexpression of GHRLOS2 on the migration and invasion abilities in HCT116 and SW480 cell lines were detected by wound healing assay and Transwell assay. Glucose content in cells of overexpressing GHRLOS2 and control cells was detected using a glucose detection kit. Western blot was used to detect the expression level of PCK1 protein in cells. The targeted binding relationship between miR-33b-5p and PCK1 was predicted based on bioinformatics methods. Results The qRT-PCR results showed that the expression level of GHRLOS2 in colorectal cancer tissue samples was lower than that in adjacent non-cancerous tissues, and was lower in colorectal cancer cells than that in normal colon epithelial cells (P < 0.05). The expression of GHRLOS2 was correlated with grade classification, staging, and lymph node metastasis (P < 0.05). The expression level of miR-33b-5p in colorectal cancer tissues was higher than that in corresponding adjacent non-cancerous tissues (P < 0.001). The results of wound healing assay, Transwell assay, and glucose content detection showed that overexpression of GHRLOS2 significantly inhibited the invasion, migration, and glucose metabolism of colorectal cancer cells. Overexpression of GHRLOS2 inhibited the expression level of miR-33b-5p; GHRLOS2 functioned as a molecular sponge for miR-33b-5p, and PCK1 was a target of miR-33b-5p; overexpression of GHRLOS2 competitively bound to miR-33b-5p, thereby promoting increased expression of PCK1. Conclusion The expression of GHRLOS2 is downregulated in colorectal cancer tissues and cells, and it may regulate the invasion, migration, and glucose metabolism of colorectal cancer cells through the miR-33b-5p/PCK1 pathway, making it a potential biological target for targeted therapy of colorectal cancer.

BACKGROUND: Clinical outcomes are poor if patients with acute heart failure (AHF) are discharged with residual congestion in the presence of renal dysfunction. However, there is no single indication to reflect the combined effects of the two related pathophysiological processes. We, therefore, proposed an indicator, congestion and renal index (CRI), and examined the associations between the CRI and one-year outcomes and the incremental prognostic value of CRI compared with the established scoring systems in a multicenter prospective cohort of AHF. METHODS: We enrolled AHF patients and calculated the ratio of thoracic fluid content index divided by estimated glomerular filtration rate before discharge, as CRI. Then we examined the associations between CRI and one-year outcomes. RESULTS: A total of 944 patients were included in the analysis (mean age 63.3 ± 13.8 years, 39.3% women). Compared with patients with CRI ≤ 0.59 mL/min per kΩ, those with CRI > 0.59 mL/min per kΩ had higher risks of cardiovascular death or HF hospitalization (HR = 1.56 [1.13-2.15]) and all-cause death or all-cause hospitalization (HR = 1.33 [1.01-1.74]). CRI had an incremental prognostic value compared with the established scoring system. CONCLUSIONS In patients with AHF, CRI is independently associated with the risk of death or hospitalization within one year, and improves the risk stratification of the established risk models.

AIM: To analyze the relationship between rs128912 single nucleotide polymorphism(SNP)in the promoter region of Toll-like receptor 3(TLR3)gene and cataract in Chinese Han population.METHODS: A total of 263 patients with cataract admitted to our hospital from June 2019 to June 2021 were selected as study group, and 150 patients with lens dislocation were included in control group. Western blotting was used to detect the expression of TLR3 protein in the anterior capsular tissues of lens in the two groups, and direct sequencing method was applied to analyze the polymorphism of rs128912 locus in the promoter region of TLR3 gene. The expression of peripheral blood TLR3 mRNA of patients with different genotypes was detected by real-time quantitative polymerase chain reaction(RT-qPCR).RESULTS: The expression level of TLR3 protein in the anterior capsular tissues in the study group was higher than that in the control group(P<0.05). The frequencies of genotypes(AA, AT, TT)at rs128912 locus in the TLR3 gene promoter region in the study group and the control group were in accordance with Hardy-Weinberg genetic equilibrium, and there were differences in the frequencies of genotypes(AA, AT, TT)and frequencies of alleles(A, T)at rs128912 locus in the TLR3 gene promoter region between both groups(P<0.05). The relative expression level of peripheral blood TLR3 mRNA in patients with TT genotype in the study group was higher than that in patients with AA or AT genotypes(P<0.05).CONCLUSION: The expression of TLR3 protein in anterior capsular tissues of lens of patients with cataract is significantly up-regulated, and rs128912 locus polymorphism in the TLR3 gene promoter region is related to the susceptibility of cataract in Chinese Han population, and people with TT genotype are more prone to cataract.

Virtue ethics and normative ethics are corresponding ethical concepts, and their collision and integration promote the development of ethical system. On the issue of doctor-patient relationship, from virtue to norm is the objective requirement of social transformation and development, and is also the inevitable choice to resolve doctor-patient conflicts and reshape doctor-patient relationships. In the new era, the construction of doctor-patient relationship faces ethical dilemma such as one-sided emphasis on doctors’ virtue cultivation, unclear ethical responsibilities between doctors and patients, and lack of trust and tolerance between doctors and patients. Therefore, it is necessary to strengthen the institutionalization of doctor ethics, clarify the ethical responsibilities of both doctors and patients, optimize the social ethical ecological environment, so as to realize the ethical reconstruction of doctor-patient relationship from virtue to norm.

【Objective】 To investigate the intrinsic relationship of social support and psychological capital with college students’ volunteer motivation in the post-epidemic era so as to provide theoretical basis for formulating policies and measures to increase college students’ participation in volunteer activities. 【Methods】 In March 2022, 1 120 college students from 15 universities in Henan Province were selected by convenient sampling method. Their general information, social support, psychological capital, and volunteer motivation were investigated, and univariate analysis, correlation analysis and intermediary effect analysis were performed. 【Results】 The differences of scores in six dimensions of volunteer motivation (i.e., values, understanding, enhancement, career, social interaction, and self-protection) were statistically significant (F=124.90, P<0.001). There were significant differences in social support level of college students of different genders (t=-2.40, P<0.05), and the difference in volunteer motivation level among different grades of college students was statistically significant (F=6.72, P<0.001). Social support, psychological capital, and volunteer motivation were positively correlated with one another (r=0.41, r=0.35, r=0.50, P<0.001). Part of the intermediary effect of psychological capital between social support and volunteer motivation was significant (intermediary effect value=0.49, 95% CI: 0.39-0.59). 【Conclusion】 Colleges and universities can take corresponding measures to improve college students’ volunteer motivation level by improving social support and psychological capital level.

Background: Benzo(a)pyrene (BaP) is a carcinogenic compound in contaminated foodstuffs.The effect of oral intake of the environmental carcinogen BaP under low doses and frequent exposure on a digestive system has not been thoroughly verified. Methods: In this regard, this study was conducted to prove the toxicity effects of BaP on the stomach and colon tissue after exposure to C57BL/6 mouse (3 and 6 µg/kg) following daily oral administration for 60 days. This study investigated acute gastric mucosal injury, severe gastric edema, cell infiltration, and mononuclear cells, multifocal cells, and tumoral inflammatory cells. Results: The results of ELISA showed that the expression of serum interleukin (IL)-6 and tumor necrosis factor-α in the BaP exposure group were significantly increased, and a high level of DNA adduct distribution in their stomach and colon. Moreover, this study has confirmed the expression of early carcinogenesis markers: nuclear factor (NF)-κB, p53, IL-6, superoxide dismutase 1 (SOD1), mucin (MUC1 and MUC2), and β-catenin in the stomach and colon, and showed that there was a significant increase in IL-6, NF-κB, SOD1, β-catenin, and MUC1 (P< 0.05). At the same time, there was a significant decrease in MUC2 and p53 (P < 0.05). Thus, even in low doses, oral intake of BaP can induce DNA damage, increasing the potential risk of gastrointestinal cancer. Conclusion This study will provide a scientific basis for researching environmental contaminated food and intestinal health following daily oral administration of BaP.
