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.

ObjectivesTo analyze the trends in mortality and disease burden of colorectal cancer (CRC) among the registered residents in Danyang City, Jiangsu Province, from 2013 to 2023, and to provide a scientific basis for developing CRC prevention and control strategies. MethodsMortality surveillance data on CRC among the registered residents in Danyang City from 2013 to 2023 were collected and analyzed. Crude mortality rate (CMR), age-standardized mortality rate (ASMR), years of life lost (YLL) due to premature death, and YLL rate were calculated. The annual percentage change (APC) and average annual percent change (AAPC) of CMR, ASMR and YLL rate were calculated with Joinpoint Regression Program 4.9.0.1. ResultsA total of 1 920 deaths from colorectal cancer were recorded in Danyang City during 2013‒2023, with an average annual CMR of 21.75/100 000, which showed an upward trend (APC=6.47%, 95%CI: 4.21%‒8.79%, P<0.001), with higher CMR observed in males than that in females. The overall ASMR by Chinese standard population was 12.10/100 000, with no obvious temporal trends (APC=1.37%, P=0.364). ASMR increased with age, particularly after 45 years. The total YLL due to CRC was 34 711 person-years, with an average YLL rate of 3.93‰. The YLL rate showed a significant upward trend from 2013 to 2023 (APC=4.96%, 95%CI: 4.08%‒18.16%, P<0.001) in Danyang City. ConclusionThe mortality rate of colorectal cancer in Danyang City is relatively high and has shown a rising trend, resulting in an increasing disease burden on the residents year by year. Continued efforts to strengthen CRC prevention and control are needed, particularly targeting males and the elderly population.

Objective To investigate the genetic characteristics of the VP1 region of Coxsackievirus A10 (CVA10) in Yunnan Province. Methods Fecal samples of suspected hand, foot and mouth disease (HFMD) were subjected to real-time fluorescent quantitative PCR for detection of enterovirus CVA10. Positive samples were subjected to VP1 gene sequence amplification and Sanger sequencing. Sequence splicing was performed with DNAstar7.1 Seqman software, and nucleotide sequence and amino acid site analysis were performed using Mega 6.0 software. Results The sequencing of VP1 gene of CVA10 obtained a sequence of 894 nucleotides, encoding 298 amino acids. Compared with the original strain, there were mainly three active amino acid mutation regions, 13-33, 141-142, and 283-285. The nucleotide difference rate between the Yunnan isolates and the reference strain ranged from 16.92% to 30.90%, and the amino acid difference rate ranged from 2.58% to 4.00%. C1 and C2 group nucleotide difference was 10.58%, and the amino acid difference rate was 1.80%. The VP1 150-176 region exhibited highly conserved characteristics. Six CVA10 strains and Sichuan strain MW178898 belonged to the C1 group of the C genotype. The other 14 CVA10 strains belonged to the C2 group. Conclusion VP1 gene mutation is active and CVA10 is an important pathogen of HFMD in Yunnan. C2 genotype of CVA10 is dominant in this study, and C1 and C2 have co-circulated in Yunnan. It is necessary to strengthen monitoring and develop multivalent vaccines containing CVA10 epidemic genotype.

Objective:To investigate the effect of "simulated Chinese medicine nursing clinic" teaching on syndrome differentiation ability among nursing students and the teaching effect of this method.Methods:A total of 325 students were randomly divided into conventional teaching group with 163 students (receiving conventional nursing teaching) and real situational teaching group with 162 students (receiving "simulated Chinese medicine nursing nursing clinic" teaching at the same time). A self-made questionnaire for syndrome differentiation-based nursing ability, assessment scores of traditional Chinese medicine nursing theories and skills, and a teaching satisfaction questionnaire were used for evaluation.Results:After intervention, the real situational teaching group (the treatment group and the experience group) had significantly higher socres of syndrome differentiation-based nursing ability (mastery of four diagnostic methods, diagnosis of syndromes, analysis of syndromes, determination of nursing principles, and development of nursing regimens) than the conventional teaching group (the treatment group and the conventional teaching group: 8.97±1.00/8.47±1.20/8.33±1.06/8.30±1.26/7.89±1.13 and 7.96±1.14/7.29±1.36/7.14±1.18/7.39±1.30/7.26±1.18, P<0.05; the experience group and the conventional teaching group: 8.39±1.10/8.17±1.15/8.07±1.06/7.97±1.26/7.73±1.38 and 7.96±1.14/7.29±1.36/7.14±1.18/7.39±1.30/7.26±1.18, P<0.05). The real situational teaching group had a significantly higher overall degree of satisfaction with teaching than the conventional teaching group [160 (97.6%) and 150 (92.0%), P<0.05]. Conclusions:The "simulated Chinese medicine nursing clinic" teaching program effectively enhances the thinking of syndrome differientiation and related abilities for nursing, improves the learning effect of traditional Chinese medicine nursing theories and skills, and increases the learning interest in traditional Chinese medicine nursing among nursing students.

Objective:To explore the HIV-1 drug resistance in patients with HIV/AIDS in Guilin city following the failure of antiretroviral treatment (ART).Methods:Plasma samples were collected from patients in Guilin who had received ART for more than 1 year and had a HIV viral load greater than or equal to 1 000 copies/ml from January 2019 to December 2023, and demographic information was also collected for HIV-1 genotype subtype analysis and drug resistance testing to determine the resistance mutation loci and the susceptibility of the strains to drugs.Results:A total of 766 patient samples with failed ART collection and successful amplification were collected, of which 536 (69.97%, 536/766) were male, with an average age of 53 years; a total of 8 HIV-1 subtypes were detected, with CRF01_AE (80.55%, 617/766), CRF07_BC (11.10%, 85/766) and CRF08_BC (6.92%, 53/766) predominated. The drug resistance analysis showed that the HIV-1 drug resistance rate was 34.86% (267/766), including nucleoside reverse transcriptase inhibitors (NRTIs), non-nucleoside reverse transcriptase inhibitors (NNRTIs) and protease inhibitor (PI), with dual resistance to NRTIs/NNRTIs (48.31%, 129/267) and NNRTIs resistance (43.07%, 115/267) predominantly. A total of 37 resistance mutation sites were detected, 14 NRTIs-associated mutation sites mainly included M184V/I (47.57%, 127/267), K65R (18.73%, 50/267), K70E/N/T/G/R (13.11%, 35/267), etc., and 18 NNRTIs-associated mutation sites mainly included K103 N/R (56.93%, 152/267), V179 D/E/T (21.72%, 58/267), G190C/S/Q (17.23%, 46/267), and V106I/M (16.85%, 45/267), etc.; and 5 PIs-associated mutation sites was the highest with L10V/I mutation rate (3.00%, 8/267).Conclusions:HIV/AIDS patients in Guilin have shown favorable outcomes in antiviral therapy, with a relatively low overall incidence of drug resistance. However, it is essential to enhance surveillance to reduce the spread of drug-resistant strains in the future.

Objective To monitor the susceptibility of clinical isolates to antimicrobial agents in tertiary hospitals in major regions of China in 2022.Methods Clinical isolates from 58 hospitals in China were tested for antimicrobial susceptibility using a unified protocol based on disc diffusion method or automated testing systems.Results were interpreted using the 2022 Clinical &Laboratory Standards Institute(CLSI)breakpoints.Results A total of 318 013 clinical isolates were collected from January 1,2022 to December 31,2022,of which 29.5％were gram-positive and 70.5％were gram-negative.The prevalence of methicillin-resistant strains in Staphylococcus aureus,Staphylococcus epidermidis and other coagulase-negative Staphylococcus species(excluding Staphylococcus pseudintermedius and Staphylococcus schleiferi)was 28.3％,76.7％and 77.9％,respectively.Overall,94.0％of MRSA strains were susceptible to trimethoprim-sulfamethoxazole and 90.8％of MRSE strains were susceptible to rifampicin.No vancomycin-resistant strains were found.Enterococcus faecalis showed significantly lower resistance rates to most antimicrobial agents tested than Enterococcus faecium.A few vancomycin-resistant strains were identified in both E.faecalis and E.faecium.The prevalence of penicillin-susceptible Streptococcus pneumoniae was 94.2％in the isolates from children and 95.7％in the isolates from adults.The resistance rate to carbapenems was lower than 13.1％in most Enterobacterales species except for Klebsiella,21.7％-23.1％of which were resistant to carbapenems.Most Enterobacterales isolates were highly susceptible to tigecycline,colistin and polymyxin B,with resistance rates ranging from 0.1％to 13.3％.The prevalence of meropenem-resistant strains decreased from 23.5％in 2019 to 18.0％in 2022 in Pseudomonas aeruginosa,and decreased from 79.0％in 2019 to 72.5％in 2022 in Acinetobacter baumannii.Conclusions The resistance of clinical isolates to the commonly used antimicrobial agents is still increasing in tertiary hospitals.However,the prevalence of important carbapenem-resistant organisms such as carbapenem-resistant K.pneumoniae,P.aeruginosa,and A.baumannii showed a downward trend in recent years.This finding suggests that the strategy of combining antimicrobial resistance surveillance with multidisciplinary concerted action works well in curbing the spread of resistant bacteria.

Objective To investigate the electrophysiological characteristics of hamster primary cortical neurons by using the whole-cell patch-clamp recordings in a Mg2+-free cell model of epilepsy.Methods The cerebral cortex were isolated for primary neuron culture from neonatal Syrian hamsters 1-2 days after birth.After 12 days,primary neurons were exposed to normal external(Mg2+group)or Mg2+-free external(Mg2+-free group)respectively for 3 hours,followed by a 24-hour incubation in normal culture medium.Excitatory postsynaptic currents(EPSC)and excitatory postsynaptic potentials(EPSP)were recorded in voltage clamp mode and current clamp mode using whole-cell patch-clamp recordings,respectively.Results Compared to Mg2+group,the frequency of EPSC[(124.38±75.15)Hz vs.(33.93±22.32)Hz,P<0.001](P<0.001)and EPSP[(37.05±38.37)Hz vs.(5.63±9.52)Hz,P<0.01]in primary cortical neurons from the Mg2+-free group increased significantly.Meanwhile,there were no statistically significant differences in the amplitude,area under the curve and half-width of EPSC and EPSP between the two groups(P>0.05).Conclusion The present study demonstrates an increase in excitability of primary hamsters cortical neurons after Mg2+depletion,suggesting that these neurons can be utilized to use to create cell models of epilepsy.

Objective To analyze the relationship between fragmented QRS(fQRS)and microalbuminuria(MAU)and serum uric acid(SUA)in patients with type 2 diabetes mellitus(T2DM).Methods From October 2022 to June 2023,245 T2DM patients diagnosed by The Department of Endocrinology,Jinhua Hospital Affiliated to Zhejiang University School of Medicine were selected and divided into fQRS group(fQRS,n=111)and T2DM group(n=134)according to ECG results.The general data,biochemical indexes,left ventricular end-diastolic diameter(LVEDd),left ventricular end-systolic diameter(LVESd),interventricular septum(IVS),left ventricular posterior wall(LVPW),left ventricular ejection fraction(LVEF),left atrial diameter(LAd),peak value ratio of mitral orifice blood flow velocity in early and late diastole(E/A)and mitral orifice blood flow velocity in early diastole were compared between the two groups.Pearson correlation analysis was used to analyze the correlation between fQRS wave and other indexes in T2DM patients,and Logistic regression analysis was used to analyze the influencing factors of fQRS.Results The prevalence rates of UACR,SUA,HbA1c and MAU in fQRS group were higher than in T2DM group(P＜0.05 or P＜0.01).LVEDd,LAd,E,E/e'and E/A>1.5 in QRS group were higher than in T2DM group(P＜0.05 or P＜0.01).Pearson correlation analysis showed that fQRS wave was positively correlated with smoking history,BMI,HbA1c,UACR,MAU,SUA,LVEDd,LAd,E/A and E/e'(P＜0.05).Logistic regression analysis showed that MAU was the influencing factor of fQRS wave in T2DM patients.Conclusions The fQRS in ECG in patients with T2DM is associated with MAU and SUA and may be an important evidence of myocardial fibrosis associated with subclinical cardiac diastolic dysfunction.
