Objective: Epothilone D (EpoD), microtubule (MT) stabilizing agent, demonstrated promising results in the animal models of Alzheimer’s disease, Parkinson’s disease and schizophrenia. The present study sought to investigate preventive effects of EpoD on altered changes of MT related proteins and endoplasmic reticulum (ER) stress proteins induced by social defeat stress (SDS). Methods: We measured protein expression levels of -tubulin and its post-translational modifications, MT-associated protein 2, stathmin1 and 2 with their phosphorylated forms, and ER stress markers, 78-kDa glucose-regulated protein (GRP-78) and CCAAT/enhancer binding protein (C/EBP)-homologous protein (CHOP) in the prefrontal cortex (PFC) and hippocampus (HIP) of C57BL/6J strain mice treated with EpoD (2 mg/kg) or its vehicle, dimethylsulfoxide (DMSO), and exposed to SDS. Results: We observed lower levels of acetylated -tubulin, MAP2, p-STMN (Ser16), and GRP-78 in the PFC of the EpoD-Con group when compared to the DMSO-Con group. On the other hand, in the HIP, there were significantly higher levels of tyrosinated -tubulin and GRP-78 in the EpoD-Defeat group compared to the DMSO-Defeat group.Furthermore, the level of MAP2 in the HIP was found to be lower in the EpoD-Con group compared to the DMSO-Con group. Conclusion Our results suggest that EpoD exhibits a dual impact, manifesting both beneficial and detrimental effects on the aberrant changes of MT-related proteins and ER stress proteins induced by SDS, depending on the brain regions.These findings underscore the complexity of EpoD’s effects, necessitating further exploration to understand its intricate mechanisms in cellular pathways linked to SDS.

Objective: Impact of Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) changes on the criteria for schizophrenia (SZ) has been reported to be minimal in previous studies. However, this could be different in first-episode schizophrenia spectrum disorders (FE-SSDs). We investigated what proportion of patients with FE-SSDs was diagnosed based on the sole presence of bizarre delusions (BDs) or first rank auditory hallucinations (FRAHs). Their alternative diagnosis by the DSM-5 was established and diagnostic stability over 1-year was identified. Methods: This was a retrospective review study on the medical records, case report forms for the subjects with FE-SSDs (n=404) participated in the Korea Early Psychosis Study. The two Japanese sites reviewed retrospectively only medical records of the subjects with FE-SSDs (n=103). We used three different definitions of BDs (strict, narrow, and broad) and specified subtypes of Other Specified Schizophrenia spectrum and Other psychotic disorders (OSSOs). To ensure inter-rater reliability between the hospitals, regular zoom meetings were held. Results: Forty (7.89%) subjects out of 507 were found to be diagnosed as SSDs based on the sole presence of BDs or FRAHs. All these patients met the criteria of OSSOs and were classified as having pure delusion (n=22), delusion with attenuated auditory hallucinations (AHs) (n=5), pure AHs (n=3) and AHs with attenuated delusion (n=10). The patients with first and second subtypes (n=27) were found to have BDs. The BDs fulfilled mostly strict definitions or satisfied the next broadest definition. The diagnostic stability of FE-OSSOs and its subgroups (first and second subtypes) over 1-year was substantially high (70.27% and 84% respectively). Conclusion These findings suggest that more rigorous diagnostic assessment should be performed especially to differentiate OSSOs from SZ in patients with FE-SSDs and more refined classification of the subtypes for OSSOs considered in the next DSM revision.

Objective:To study the results of detection of pulmonary nodules among military flying personnel and analyze the contributors to pulmonary nodules so as to provide data for early prevention and interventions.Methods:The physical examination data of 1 465 military flying personnel was retrospectively analyzed who had received the annual health checkup and undergone chest CT examinations at Lintong Rehabilitation and Recuperation Center. They were grouped by age (<40 years and ≥40 years), flying hour (<1 000 h and ≥1 000 h) and type of personnel [pilots and air support (technical) personnel]. The detection rates of pulmonary nodules among flying personnel were compared across groups, and a multivariate Logistic regression analysis was conducted to analyze the contributing factors to pulmonary nodules.Results:Among the 1 465 military flying personnel, 212 cases (14.47%) with pulmonary nodules were detected. A total of 230 pulmonary nodules were detected, including 35 pulmonary nodules (15.22%) in the left upper lung, 42 pulmonary nodules (18.26%) in the left lower lung, 52 pulmonary nodules (22.61%) in the right upper lung, 47 pulmonary nodules (20.43%) in the right middle lung, and 54 pulmonary nodules (23.48%) in the right lower lung. The detection rate of pulmonary nodules among military flying personnel in the ≥1 000 h group was higher than in the <1 000 h group, and the difference was statistically significant ( χ2=4.14, P=0.042). More pulmonary nodules were detected among military flying personnel who smoked than among those who did not, and the difference was statistically significant ( χ2=9.34, P=0.002). Age, types of personnel, body mass index, and complications with other lung diseases made no significant difference in the detection rate of pulmonary nodules (all P>0.05). Multivariate Logistic regression analysis showed that smoking was a risk factor for pulmonary nodules ( OR=1.692, 95% CI: 1.217-2.351). Conclusions:Among military flying personnel, pulmonary nodules are more likely to occur in the right lung. Smoking is an independent risk factor for pulmonary nodules, suggesting that routine chest CT screening should be carried out during the annual physical examinations of military flying personnel in order to exercise early interventions.

Objective To compare the clinical effect of tympanoplasty with and without eustachian tube bal-loon dilatation(ETBD)in the treatment of adhesive otitis media(AOM).Methods A total of 43 patients with AOM and eustachian tube dysfunction(ETD)were retrospectively analyzed,and were divided into the experimental group(n=22)who underwent tympanoplasty combined with ETBD and the control group(n=21)who underwent tympanoplasty alone.The changes of average air conduction hearing thresholds,pure-tone air-bone gap(ABG)and eustachian tube score(ETS)were compared between the two groups before and after surgery at 6 months and 2 years.Results There were no significant differences between the experimental group and the control group in air conduction hearing thresholds,ABG and ETS before operation(P＞0.05).Comparison within both the two groups after operation:air conduction hearing thresholds and ABG in both groups were significantly reduced(P＜0.05),and ETS in the experimental group was significantly higher than that before surgery(P＜0.05).Comparison be-tween two groups after operation:there were no statistically significant differences in the air conduction hearing thresholds and ABG at 6 months after surgery(P＞0.05),while there was statistically significant difference in ETS(P＜0.05).At 2 years,there were statistically significant differences in the air conduction hearing thresholds,ABG and ETS between the two groups(P＜0.05)with the experimental group showing better outcomes.Conclusion Tympanoplasty can significantly improve the postoperative hearing of AOM.Tympanoplasty combined with ETBD not only effectively improves the eustachian tube function,but also shows better long-term follow-up hearing im-provement,making it an effective treatment for AOM patients.

Objective:To investigate the application effect of an information platform-based chain management model in postoperative chemotherapy patients with breast cancer.Methods:A total of 126 patients with breast cancer who underwent chemotherapy after surgery were selected from Sep 2021 to Apr 2024 and randomly divided into two groups by random sampling method,with 63 cases in each group.They all received at least 3 cycles of chemotherapy.The control group received routine nursing care,while the observation group received the information platform-based chain management model based on information platform in addition to routine nursing.The compliance with chemotherapy,incidence of adverse events related to peripherally inserted central catheter(PICC)was compared between the two groups.Strategies used by people to promote health(SUPPH),Self-care Ability of PICC(CPPSM),and functional assessment of cancer therapy-breast(FACT-B)were used to compare the self-management efficacy,self-care ability and quality of life between the two groups.Results:The compliance rate of chemotherapy in the observation group was higher than that in the control group(P＜0.05).After the first and third chemotherapy,the scores of SUPPH,CPPSM,and FACT-B in the observation group were higher than those in the control group(P＜0.05).The incidence of adverse events related to PICC in the observation group was lower than that in the control group(P＜0.05).Conclusion:The information platform-based chain management model can improve the chemotherapy compliance,enhance self-care capacity and self-management efficacy,reduce PICC-related adverse events,and ultimately elevate quality of life in postoperative breast cancer patients.
