Objective:
To investigate the expression and functional role of FK506 binding protein 10 (FKBP10) in oral squamous cell carcinoma (OSCC), and to provide a research basis for the estimated prognosis and targeted therapy of OSCC.
Methods:
A total of 284 OSCC samples and 19 normal samples were selected from the Cancer Genome Atlas (TCGA) database, and diagnostic analysis was performed to determine mRNA expression. Survival analysis for FKBP10 and OSCC was conducted on a gene expression profile interaction analysis website. Real-time fluorescence quantitative PCR and Western Blot were used to detect the mRNA and protein expression of FKBP10 in four OSCC cell lines and SAS and SCC9 cells transfected with siRNA. The cell proliferation ability of FKBP10-silenced cells was detected using the CCK8 method, and the cell cycle distribution and apoptosis were detected by flow cytometry. Cell migration and invasion ability were detected through wound healing and invasion experiments. The expression changes of total protein and phosphatidylinositol 3-kinase (PI3K)-serine/threonine kinase (AKT) after FKBP10 silencing were analyzed by proteomics and Western Blot.
Results:
According to the analysis of gene expression levels, the mRNA expression level of FKBP10 in OSCC was significantly higher than that in normal tissues (P < 0.001). In terms of diagnosis, the expression level of FKBP10 has unique diagnostic value for OSCC (P < 0.05). The survival analysis of FKBP10 and OSCC showed that a high expression of FKBP10 led to a decrease in patient survival and poor prognosis (P < 0.05). The expression of FKBP10 mRNA and protein in OSCC cell lines was higher than that in normal oral keratinocytes (P < 0.001). Silencing FKBP10 can reduce the proliferation, invasion, and migration ability of SAS and SCC9 (P < 0.001), and also block their cell cycle in the G0/G1 phase (P < 0.001), with a significant increase in apoptosis (P < 0.05). Protein mass spectrometry and Western blot analysis revealed that FKBP10 silencing significantly downregulated the expression of multiple proteins in the RAP1 signaling pathway, mainly RAP guanine nucleotide exchange factor 1 (RAPGEF1) (P < 0.05) and the phosphorylation of PI3K-AKT proteins (P < 0.05).
Conclusion
FKBP10 is highly expressed in OSCC, leading to poor prognosis for patients. Downregulated FKBP10 expression can inhibit the proliferation, migration, and invasion ability of OSCC cells, hinder cell cycle progression, and promote apoptosis via the RAP1-PI3K-AKT axis. FKBP10 is a potential therapeutic target and prognostic biomarker for OSCC.

OBJECTIVE To study the effects of the curcumin derivative bisdemethoxycurcumin (BC) promoting neuronal differentiation of neuroblastoma cells Neuro-2a (N2a) in mice and its mechanism. METHODS The effects of BC (1, 2, 4, 6, 8, 10 μmol/L) on the viability of N2a cells were detected by MTT assay to determine the concentration range of drug treatment. The control group, retinoic acid (RA) group (10 μmol/L) and BC groups (1, 2 and 4 μmol/L) were set up, and the length of neural protrusions of the differentiated cells was measured and the cell differentiation rate was calculated after 48 h and 72 h of culture. Compared with 0 min group, Western blot was used to detect the phosphorylation levels of protein kinase B (Akt), extracellular- signal regulated kinase 1/2 (ERK1/2), and p38 mitogen-activated protein kinase (p38) proteins in cells treated by 4 μmol/L BC for 5, 15, 30, 60, 120 min. After intervention with inhibitors LY294002 (LY) and PD98059 (PD), the effects of BC on Akt and ERK1/2 protein phosphorylation levels and promoting neural differentiation were further validated. RESULTS According to the MTT experiment, the BC concentrations for subsequent induction of cell differentiation were determined to be 1, 2, and 4 μmol/L. After 48 hours of differentiation, compared with the control group, the cell differentiation rate in RA group and BC 1, 2 and 4 μmol/L groups, the length of cellular neural processes wjxhhxx413@163.com in the BC 4 μmol/L group significantly increased (P<0.05 or P<0.01);after inducing differentiation of BC for 72 hours,compared with the control group, the cell differentiation rate and the length of cellular neural processes in the RA group, the cell differentiation rate in the BC 4 μmol/L group, and the length of cellular neural processes in the BC 2 μmol/L group all significantly increased (P<0.05 or P<0.01).Compared with the 0 min group, the phosphorylation levels of Akt, ERK1/2, and p38 proteins in cells of the 5, 15, 30, 60 and 120 min groups increased to varying degrees after treated by 4 μmol/L BC, and some differences were statistically significant (P<0.05 or P<0.01). After adding the inhibitor LY/PD, compared with the BC group, the phosphorylation level of ERK1/2 protein in the PD+BC group cells were significantly reduced (P<0.01), and the cell differentiation rates in the LY group, LY+BC group, PD group, and PD+BC group was significantly reduced (P<0.01). CONCLUSIONS BC promotes N2a cell differentiation mainly by increasing cell differentiation rate and neural protrusion length. The mechanism may be related to the activation of mitogen-activated protein kinase/ ERK and PI3K/Akt signaling pathways.

ObjectiveTo examine the inhibitory effects of berberine compounds, including columbamine, on acetylcholinesterase from the perspectives of drug-target binding affinity and kinetics and explore the blood-brain barrier (BBB) permeability of these compounds in different multi-component backgrounds. MethodThe median inhibitory concentration (IC50) of acetylcholinesterase by berberine compounds including columbamine was measured using the Ellman-modified spectrophotometric method. The binding kinetic parameters (Koff) of these compounds with acetylcholinesterase were determined using the enzyme activity recovery method. A qualitative analysis of the ability of these components to penetrate the BBB and arrive at the brain tissue in diverse multi-component backgrounds (including medicinal herbs and compound formulas) was conducted using ultra performance liquid chromatography-high resolution mass spectrometry (UPLC-HRMS). ResultBerberine compounds, including columbamine, exhibited strong inhibition of acetylcholinesterase, with IC50 values in the nanomolar range. Moreover, they displayed better drug-target binding kinetics characteristics (with smaller Koff values) than the positive control of donepezil hydrochloride (P<0.01), indicating a longer inhibition duration of acetylcholinesterase. Berberine components such as columbamine could penetrate the BBB to arrive at brain tissue in the form of a monomer, as well as in the multi-component backgrounds of Coptis and Phellodendri Chinensis Cortex medicinal extracts and the compound formula Huanglian Jiedutang. ConclusionThese berberine compounds such as columbamine exhibit a strong inhibitory effect on acetylcholinesterase and can arrive at brain tissue in multi-component backgrounds. In the level of pharmacological substance, this supports the clinical efficacy of compound Huanglian Jiedutang in improving Alzheimer's disease, providing data support for elucidating the pharmacological basis of compound Huanglian Jiedutang.

ObjectiveTo evaluate the clinical effectiveness and safety of Bairui Granules (百蕊颗粒) in the treatment of acute pharyngitis with wind-heat syndrome. MethodsA multicenter, double-blind, double-simulation, randomised controlled trial was conducted, in which 162 patients with acute pharyngitis and wind-heat syndrome from 7 centers were recruited, and each center was divided into trial group and control group on the ratio of 2∶1. In the trial group, 108 cases were orally administered with Bairui Granules plus Reyanning Granules (热炎宁颗粒) simulant, and in the control group, 54 cases were orally administered with Reyanning Granules plus Bairui Granules simulant for 5 days, with a follow-up visit on the 6th day. Full analysis set (FAS) analysis and per protocol set (PPS) were used for analysis, respectively. The primary efficacy index was the disappearance rate of sore throat after 5-day treatment; the secondary efficacy indexes were the disappearance rate of sore throat after 3-day treatment, as well as the visual analogue score (VAS) of sore throat before treatment, every day during the treatment, and follow-up on day 6, and the traditional Chinese medicine (TCM) syndrome score was performed before treatment and at the follow-up on day 6. The effectiveness on TCM syndrome was evaluated at the follow-up on day 6, and the changes of vital signs, blood routine, urine routine, liver functions, kidney function, the adverse events before and after the treatment were recorded, and safety analysis set (SS) was analysed. Results162 patients entered the FAS and SS analyses, and 158 cases (105 cases in the trial group and 53 cases in the control group) entered the PPS analysis. FAS analysis showed that the disappearance rate of sore throat after 5-day treatment was 80.56% (87/108) in the trial group and 64.81% (35/54) in the control group, and the difference between groups was statistically significant (χ2 = 5.10, P = 0.0239). PPS analysis showed that the disappearance rate of sore throat after 5-day treatment was 80.00% (84/105) in the trial group and 64.15% (34/53) in the control group, and the difference between groups was statistically significant (χ2 =4.85, P = 0.0277). FAS and SS analyses both showed that the difference in disappearance rate of sore throat between groups on 3-day treatment was not statistically significant (P>0.05). Compared with those before treatment, the VAS scores of sore throat were lower in both groups during treatment on day 2, 3, 4, 5, and follow-up on day 6 (P<0.01), but the difference between groups at each time point was not statistically significant (P>0.05). TCM syndrome scores of both groups at the follow-up were lower than that before treatment, and those of the trial group were lower than those of the control group (P<0.01). The cure rate and effective rate of TCM syndrome of the trial group were significantly higher than those of the control group (P<0.01). There was no significant difference in blood routine, urine routine, liver function, kidney function between groups before and after treatment (P>0.05), and no serious adverse events occured in both groups. ConclusionBairui Granules showed clinical effectiveness in the treatment of acute pharyngitis of wind-heat syndrome, and it could significantly improve the clinical symptoms, accelerate the disappearance time of sore throat with good safety.
8.Correlation between refractive development and physical growth indices in primary school students aged 6-9 years in Guangdong Province
Chinese Journal of School Health 2024;45(7):936-940
Objective:
To analyze the correlation between refractive errors and physical development indicators among primary school students aged 6 to 9, so as to provide a scientific basis for the development of effective prevention and control measures.
Methods:
A stratified cluster random sampling method was used to recruit 2 833 elementary school students aged 6 to 9 from Guangdong Province for vision screening, ocular biometry, and physical examinations in Octorber, 2020. The Chi square test, t-test, and ANOVA were employed to compare myopia rates and indicator values across different groups. Multiple linear regression models were used to analyze the correlations between height, weight, and body mass index (BMI) with refractive development indicators.
Results:
The screening myopia rate among primary school students aged 6 to 9 was 16.7%, and the myopia rate increased with age ( χ 2= 51.58 , P <0.01). The height and weight of the myopic group [(126.96±7.41)cm, (26.59±6.45)kg] were higher than those of the non myopic group [(124.76±7.77)cm, (25.42±5.87)kg] ( t =5.84, 3.65, P <0.01). The mean values of spherical equivalent (SE), axial length (AL), anterior chamber depth (ACD), and AL/corneal curvature radius (CR) ratio for students aged 6 to 9 were (-0.17±1.04)D, (22.96±0.78)mm, (3.38±0.24)mm, and (2.95±0.08), respectively, with statistically significant differences across different age and myopia severity groups ( t =37.08, 119.20, 41.54, 133.60; 935.30, 184.10, 73.95, 498.50, P < 0.01). After adjusting for gender, age, and residence, the multiple linear regression model showed that height was positively correlated with AL and CR, weight was positively correlated with ACD, and BMI was positively correlated with AL and ACD ( β = 0.191 , 0.070, 0.035, 0.013, 0.007, P <0.05). When stratified by myopia status, results for the non-myopic group were similar to the overall results, whereas in the myopic group, the correlations between height, BMI, and AL were not statistically significant ( P > 0.05).
Conclusions
Among primary school students aged 6 to 9, height and BMI are positively correlated with AL in the non myopic group but no similar correlation is observed in the myopic group, indicating that factors other than physical development, such as environmental and behavioral factors, should be considered for their impact on refractive development.

This article is to illustrate the connection between neutrophil extracellular traps (NETs) and stasis-toxin interactions during the development of liver cancer, and to provide ideas for the prevention and treatment of liver cancer. It is believed that the mechanism of tumor-related thrombosis formation caused by NETs is closely related to "stasis" in traditional Chinese medicine (TCM), and the continuous maintenance or enhancement of tumor microenvironment by NETs is closely related to "toxin" in TCM; the strong coagulation-promoting effect of NETs makes the local microenvironment, which can be regarded as the toxin caused by blood stasis; the changes of tumor microenvironment induced by NETs further induced platelet aggregation, which may present a state of stasis caused by toxin; the pathological changes of liver cancer caused by NETs can be regarded as the microscopic manifestation of the mechanism of stasis-toxin interaction of liver cancer.
