Objective To investigate the differences in personality traits between the patients with anx-ious depression(AND)and non-anxious depression(NAD)in order to provide the possible basis for early find of the patients with AND.Methods A total of 572 adult patients with depression visiting in the psychiatric outpatient department of the First Affiliated Hospital of Chongqing Medical University from January 2022 to December 2022 were selected to conduct the questionnaire survey.General demographic questionnaire,Self-rating Depression Scale(SDS),Generalized Anxiety Disorder Scale(GAD-7)and Minnesota Multiphasic Per-sonality Inventory(MMPI)were collected and analyzed.The patients with GAD-7 total score ≥5 points served as the AND group(n=499)and those with GAD total score＜5 points served as the NAD group(n=73).The correlation between the general demographic questionnaire,SDS and GAD-7 with MMPI was ana-lyzed.Results There were statistically significant differences in the place of residence,number of children in a family,education years,MMPI total score and high score proportions of psychopathy,athopia,hysteria,depres-sion,hypochondriasis,paranoea,schizophrenia,social introversion and hypomania dimensions between the two groups(P＜0.05).The SDS and GAD-7 scores in the AND group were higher than those in the NAD group(P＜0.05).The MMPI total score,athopia,hysteria,depression,hypochondriasis,paranoea,schizophrenia,so-cial introversion and hypomania were positively correlated with SDS and GAD-7(P＜0.05).Conclusion The patients with depression accompanied by anxiety symptom could be early identified by the MMPI testing results.

Objective To investigate the relationship between cyclin A2 (CCNA2) and the prognosis of colon cancer, and its possible mechanism from the perspective of immune infiltration. Methods We downloaded the transcriptome data of colon cancer patients from The Cancer Genome Atlas database. Clinicopathological feature analysis and survival analysis were performed based on the expression levels of CCNA2. A total of 75 specimens of colon cancer and normal tissues were collected, and the expression level of CCNA2 was analyzed using immunohistochemical methods. Multivariate analysis was conducted to explore its relationship with clinicopathological features. Gene Set Enrichment Analysis (GSEA) was used to assess the potential molecular functions of CCNA2 in colon cancer. CIBERSORT algorithm was applied to calculate the correlation between CCNA2 and immune-cell infiltration in colon cancer. Results Database and immunohistochemical analyses indicated that CCNA2 was expressed at a significantly higher level in colon cancer tissues than normal tissues (P<0.001). The overall survival, disease-specific survival, and progression-free interval were all longer in the group with high CCNA2 expression than the group with low expression (all P<0.05). In tumor tissues, the expression level of CCNA2 decreased with increased pathological and TNM stages (P<0.05). The expression level of CCNA2 in normal tissues was consistently lower than that in colon cancer tissues across all clinical stages (all P<0.001). GSEA suggested that Wnt/β-catenin, KRAS, and other signaling pathways were enriched when CCNA2 was lowly expressed. CIBERSORT analysis revealed an increase in the infiltration of immune cells such as regulatory T cells and macrophages M0 when CCNA2 expression was low. Conclusion CCNA2 is highly expressed in colon cancer and closely associated with grade of pathology and TNM stage. It may recruit regulatory T cells through the KRAS and Wnt/β-catenin pathways, thereby reducing immune-cell infiltration and promoting colon cancer progression, leading to poor prognosis.

Objective To analyze the quality of medical record home pages for discharged patients in a tertiary hospital in Guangzhou in 2023 based on the dual dimensions of Diagnosis-Related Groups(DRG)and Disease Intervention Program(DIP),and to provide a basis for improving the refinement of medical record home page quality management.Methods Dis-charge medical records from a tertiary general hospital in 2023 were selected.All medical records were grouped using DRG,while medical records under Guangzhou medical insurance and cross-province medical insurance implemented under DIP were simulated for DIP grouping.The writing defects in the discharge medical records were analyzed,as well as the DRG grouping,RW,and DIP standard scores of medical records with home page filling defects.Results Among 172 230 discharge medical records,171 786 were grouped into DRG,91 768 were grouped into DIP,and 91 604 were grouped into both DRG and DIP.A significant positive correlation was found between RW and DIP standard scores(r2=0.681,P＜0.001).Among the 91 604 medical records grouped into both DRG and DIP,1 942(2.12％)had writing defects,including 837(0.91％)with home page defects.DRG groups with more home page defect records included NC15,HK2,EJ13,EB15,HJ13,and RE19.Conclusion Quality defects in medical record home pages impact the accuracy of DRG and DIP grouping.Systematic measures such as strengthening medical record writing training and establishing scientific reward and punishment mechanisms should be implemented to provide data sup-port for the further advancement of DRG/DIP payment reform.

Osteoporosis is a prevalent skeletal condition characterized by reduced bone mass and strength, leading to increased fragility. Buqi-Tongluo (BQTL) decoction, a traditional Chinese medicine (TCM) prescription, has yet to be fully evaluated for its potential in treating bone diseases such as osteoporosis. To investigate the mechanism by which BQTL decoction inhibits osteoclast differentiation in vitro and validate these findings through in vivo experiments. We employed MTS assays to assess the potential proliferative or toxic effects of BQTL on bone marrow macrophages (BMMs) at various concentrations. TRAcP experiments were conducted to examine BQTL's impact on osteoclast differentiation. RT-PCR and Western blot analyses were utilized to evaluate the relative expression levels of osteoclast-specific genes and proteins under BQTL stimulation. Finally, in vivo experiments were performed using an osteoporosis model to further validate the in vitro findings. This study revealed that BQTL suppressed receptor activator of NF-κB ligand (RANKL)-induced osteoclastogenesis and osteoclast resorption activity in vitro in a dose-dependent manner without observable cytotoxicity. The inhibitory effects of BQTL on osteoclast formation and function were attributed to the downregulation of NFATc1 and c-fos activity, primarily through attenuation of the MAPK, NF-κB, and Calcineurin signaling pathways. BQTL's inhibitory capacity was further examined in vivo using an ovariectomized (OVX) rat model, demonstrating a strong protective effect against bone loss. BQTL may serve as an effective therapeutic TCM for the treatment of postmenopausal osteoporosis and the alleviation of bone loss induced by estrogen deficiency and related conditions.

Objective To evaluate the feasibility of confirming syphilis reactive blood donors.Methods The serum of donors with anti-TP reaction by ELISA were confirmed by treponema pallidum particle agglutination(TPPA)and Western blotting(WB).The results of two confirmation methods that were negative,suspicious or inconsistent were followed up and compared.At the same time,the analytical index values of the screening reagent A,B and C and their combinations were e-valuated and compared using the the receiver operating characteristic curve(ROC curve)based on the results of the two confirmation methods.Results The positive rate of 223 ELISA anti-TP reactive samples(including 124 double-reagent ELISA reactive samples and 99 single-reagent ELISA reactive samples)was 57.40%confirmed by TPPA and 38.57%con-firmed by WB(89.52%vs 17.17%by TPPA and 52.42%vs 21.21%by WB for double-reagent and single-reagent ELISA reactive samples).The confirmed negative rate of TPPA was 35.43%and that of WB was 42.60%(6.45%vs 71.72%of TP-PA and 29.84%vs 58.59%of WB for double-reagent and single-reagent ELISA reactive samples).According to Kappa test,the confirmed results between the two methods were not consistent,especially for those single-regent ELISA reactive sam-ples.Thirty six cases were followed up successfully,of which 17(47.22%)confirmed changes in the test results but the changes were irregular.Based on the confirmed results of TPPA and WB,the ROC curve analysis was performed on the anti-TP screening S/CO values of double-reagent ELISA reactive samples.When combining ELISA screening reagents as A/B and A/C,the optimal S/CO values of reagent A were 1.815,5.73 and 10.205,16.165,respectively.Conclusion TPPA and WB have poor consistency in the confirmation of ELISA anti-TP reactive blood samples,and the outcome of follow-up confirmation is unclear.The S/CO threshold of ROC curve is affected by the combination of confirmatory screening reagents,and it is difficult to confirm the results of ELISA anti-TP reactive blood donors.
