BackgroundSika deer (Cervus nippon Temminck, 1838) antler is a highly esteemed tonic renowned for its abundant assortment of polypeptides, polysaccharides, amino acids, and minerals, and is recognized for its multifarious pharmacological properties. However, limited research has been conducted regarding the variation in composition of deer antlers between the upper and basal sections, as well as their pharmacological effects on immunological activity and anti-fatigue in mice. The objective of this study was to conduct a comprehensive analysis on the appearance, chemical composition, and pharmacological effects of different components within sika deer antlers. This investigation aims to elucidate the disparities in quality among various parts of antlers and establish a theoretical foundation for the precise utilization of sika deer antlers.MethodsThe contents of protein, amino acids, polysaccharides, phospholipids, minerals and nucleotides in wax, powder, gauze and bone slices were determined by different nutrient assays. Then, 100 mice were randomly divided into 5 groups. The mice in control group were administered 0.3 mL of saline solution per day. The mice in experimental groups were administered 0.3 mL enzymatic hydrolysate of the wax slice, powder slice, gauze slice, bone slice separately per day, continuously for 14 days from the first day. The effect of antler on boosting immunity was evaluated by testing organ indices and assessing immunoglobulin levels by ELISA. Anti-fatigue effects were assessed by a mouse swimming test. Finally, the correlation between composition and pharmacological effects was analysed.ResultsThe content of each marker substance gradually decreases from the upper to the basal of deer antler. The protein and uracil content in the wax slice were significantly higher than the other three groups (p < 0.05), and the phospholipid and inosine content were strongly significantly higher than the other three groups (p < 0.01). The content of polysaccharides and hypoxanthine in the wax slice group and powder slice group was significantly higher than that in the gauze slice group and bone slice group (p < 0.05). The amino acid content decreases from the upper to the basal section. Among, the content of Glu, Gly, His, and Pro wax slice was significantly higher than the other three groups (p < 0.01). The content of other minerals except Fe and Mg in the wax slice group was significantly higher than the other three groups (p < 0.01), and the content of Fe and Mg in the bone slice was the highest. Additionally, the immune organ index, immunoglobulin, and glycogen contents displayed a significant increase in comparison to both the control group and the other experimental groups (p < 0.05). And the swimming endurance of mice in the wax slice group was significantly prolonged (p < 0.01). The skeletal muscle state of the wax group mice exhibited superior characteristics, characterized by distinct horizontal stripes and tightly arranged muscle fibers. In contrast, the bone group displayed noticeable yet relatively less compact horizontal stripes. Among the organic and inorganic compositions of deer antler, the highest degree of correlation with the content of IgA, IgM, and IgG was found to be protein (r2 = 0.999), uracil (r2 = 0.987), and inosine (r2 = 0.999), respectively. The proteins (r2 = 0.997) appear to exert a significant influence on the anti-fatigue effect, while polysaccharides (r2 = 0.865) demonstrate the least relevance.ConclusionThese outcomes indicated that the wax slice yielded optimal results among the tested parts and demonstrated the highest efficacy.

ObjectivesTo analyze obstructive sleep apnea (OSA)-related quality of life (QoL), the statuses of depression and anxiety, and to reveal the correlation between OSA-related QoL and two mental statuses in Chinese adolescent patients with cleft palate (CP).MethodsThe Obstructive Sleep Apnea Questionaire-18 (OSA-18), the Generalized Anxiety Disorder Scale (GAD-7) and the Patient Health Questionnaire-9 (PHQ-9) were applied to assess OSA-related QoL and the statuses of anxiety and depression in Chinese adolescent patients with CP, respectively. Non-CP adolescents were also included in the control group. OSA-related QoL and the two mental statuses were compared between the study and control groups. The correlation between the OSA-related QoL and two mental statuses was estimated in Chinese adolescent patients with CP.ResultsA total of 8.7% patients showed a moderate or high impact of OSA on QoL, while all the adolescents from the control group showed little impact. The mean total OSA-18 score of the study group (36.261 ± 13.500) was significantly higher than the control (28.435 ± 8.934). The mean PHQ-9 scores of the study group and the control group were statistically different (3.957 vs. 2.113). The GAD-7 score in the study group was slightly higher than the control group (3.043 vs. 2.194), while the proportion of moderate-severe anxiety in the study group was relatively larger than that in the control group (6.5% vs. 1.6%). Moreover, there was a positive correlation between the OSA-related QoL and the statuses of anxiety and depression respectively, and the differences in GAD-7 and PHQ-9 scores between the moderate or high impact group and the little impact group were statistically significant.ConclusionChinese adolescents with CP reported a rate of moderate or high impact of OSA on QoL of 8.7%, which was significantly higher than adolescents without CP. The OSA-related QoL was worse and depression was severer in Chinese CP adolescents than in the control, while anxiety and depression in Chinese CP adolescents were associated with OSA-related QoL.

ObjectivesTo preliminarily analyze factors that affected the prevalence of anxiety in Chinese patients with cleft lip and/or palate (CL/P).MethodsThe Generalized Anxiety Disorder Scale (GAD-7) was used to screen anxiety in Chinese CL/P patients. Non-CL/P individuals were also included as the control group. Sociodemographic and clinical data consisting of diagnosis, gender, only child or not, monthly household income, and current family location were collected to analyze possible factors that could affect the anxiety of this patient population.ResultsOne hundred forty-two and 78 valid questionnaires were collected from the study and control groups, respectively. The mean GAD-7 score of the study group (3.092 ± 3.381) was significantly lower than the control (3.987 ± 2.505). Moreover, the proportion of patients presenting with moderate-severe anxiety was larger in the study group than in the control group (6.6 vs. 0.0%). Statistically significant differences in GAD-7 scores were observed between the study and control groups when the patient was the only child, living in an urban area, or the monthly household income was between 1,000 and 5,000 yuan.ConclusionAlthough the severity of anxiety in Chinese CL/P patients was not severer than those without CL/P, there was a relatively high incidence of moderate-severe anxiety in CL/P patients, while the only child, current family location and the monthly household income played significant roles in affecting anxiety psychology.

To explore the role of metastasis-related long noncoding RNA (lncRNA) signature for predicting the prognosis of clear cell renal cell carcinoma (ccRCC) patients. Firstly, metastasis-associated genes were identified to establish a metastasis-related lncRNA signature by statistical analysis. Secondly, the ccRCC patients were grouped into high-risk or low-risk group according to the established signature, and the different pathways between the 2 groups were identified by gene set enrichment analysis (GSEA). Finally, investigations involving PCR, transwell migration and invasion assay were carried out to further confirm our findings. The metastasis-related lncRNA signature was successfully constructed according to 7-metastasis-related genes (ADAM12, CD44, IL6, TFPI2, TGF-β1, THBS2, TIMP3). The diagnostic efficacy and the clinically predictive capacity of the signature were evaluated. Most of the values of the area under the time‐dependent receiver‐operating characteristic (ROC) were greater than 0.70. The nomogram constructed by integrating clinical data and risk scores confirmed that the risk score calculated from our signature was a good prognosis predictor. GSEA analysis showed that some tumor-related pathways were enriched in the high-risk group, while metabolism-related pathways were enriched in the low-risk group. In carcinoma tissues, the SSR3-6, WISP1-2 were highly expressed, but the expression of UBAC2-6 was low there. Knocking down SSR3-6 decreased the ability of migration and invasion in ccRCC cells. In conclusion, we successfully constructed a metastasis-related lncRNA signature, which could accurately predict the survival and prognosis of ccRCC patients.
