Objective To explore the effects of breast-conserving surgery (BCS), simple mastectomy (SM), and modified radical mastectomy (MRM) on early postoperative upper limb motor function, physical and psychological status in breast cancer patients. Methods A total of 212 female breast cancer patients undergoing surgery at the Department of Breast Surgery of Zhangzhou Affiliated Hospital of Fujian Medical University from October 2024 to December 2025 were enrolled. Patients were divided into the BCS group (n＝34), SM group (n＝79), and MRM group (n＝99). General demographic and clinical data were collected. At 3–7 days postoperatively, the Constant-Murley score (CMS), active range of motion (AROM) of the shoulder joint, and the Quick Disabilities of the Arm, Shoulder and Hand (QuickDASH) score were used to assess upper limb function; the Generalized Anxiety Disorder-7 (GAD-7), Patient Health Questionnaire-9 (PHQ-9), Functional Assessment of Cancer Therapy-Breast (FACT-B), and Pittsburgh Sleep Quality Index (PSQI) were used to evaluate patients’ psychological status, quality of life, and sleep quality. Results The total CMS score, pain score, and range of motion score in the BCS group were higher than those in the SM and MRM groups (P＜0.05). The BCS group showed greater forward flexion range of motion than that in the SM and MRM groups (P＜0.05); and the SM group showed smaller internal rotation range of motion than that in the MRM and BCS groups (P＜0.05). The PHQ-9 depression score in the BCS group was significantly higher than that in the MRM group (P＜0.05). There were no statistically significant differences among the three groups in QuickDASH, GAD-7, FACT-B, or PSQI scores. Conclusions Early postoperative upper limb function and depression status varied among breast cancer patients undergoing different surgical procedures. Patients undergoing BCS had better preservation of upper limb function but higher depression scores.

Brain imaging abnormalities are present in schizophrenia (SZ) and bipolar disorder (BD), demonstrating disease-specific changes, yet they also share similarities in certain brain regions or functional characteristics, with SZ potentially exhibiting more extensive brain damage compared to BD. Structural magnetic resonance imaging (MRI) studies demonstrated widespread gray matter reductions in SZ, particularly in the prefrontal and temporal lobes. In BD, gray matter thickening was observed in the prefrontal lobes during manic episodes, while a reduction in gray matter was noted in the amygdala and hippocampus during depressive episodes. Both SZ and BD exhibited increased ventricular volume and reduced overall brain volume. Functional MRI studies revealed reduced functional connectivity in the prefrontal and temporal lobes in SZ, with decreased global and local efficiency in brain regions such as the hippocampus and cingulate gyrus. BD showed enhanced connectivity in the anterior cingulate gyrus and the default mode network (DMN). Both SZ and BD demonstrated altered functional connectivity in areas such as the striatum, salience network, central executive network and DMN. Diffusion tensor imaging studies showed decreased fractional anisotropy (FA) in the corpus callosum of SZ, with a decrease in FA in the left fronto-occipital fasciculus in BD. Both SZ and BD exhibited reduced FA in the uncinate fasciculus and corpus callosum. Magnetic resonance spectroscopy revealed decreased concentrations of glutathione, N-acetylaspartate (NAA) and inositol in the anterior cingulate gyrus of SZ. In BD, glutathione and inositol concentrations were elevated in the anterior cingulate gyrus, while NAA levels decreased during depressive episodes and increased during remission. Both SZ and BD showed increased levels of glutamate and gamma-aminobutyric acid in the prefrontal cortex. This article provides a review of the current evidence on the differences and similarities in multimodal magnetic resonance brain imaging between SZ and BD, aiming to offer a reference for future exploration of neuroimaging biomarkers and the neurobiological mechanisms of SZ and BD.

Objective:To investigate the clinical significance of tumor budding as an indicator of postoperative distant organ metastasis after radical gastrectomy in elderly patients diagnosed with gastric cancer.Methods:The clinical and pathological data of 124 elderly patients who experienced metastasis after undergoing radical gastrectomy were retrospectively analyzed.The analysis was conducted from March 2015 to June 2022, focusing on the clinicopathological factors that influenced the occurrence of postoperative distant metastasis in these patients.Tumor budding in gastric cancer tissues was assessed using hematoxylin-eosin staining, and its clinical significance was analyzed.Results:The tumor budding grade of gastric cancer tissues showed a significant correlation with vascular invasion( χ2=6.731, P=0.009), the number of lymph node metastases( rs=0.481, P<0.001), and the time of distant metastasis( rs=-0.450, P<0.001).In the univariate analysis, factors such as tumor budding grade, tumor size, vascular invasion, postoperative chemotherapy, cancerous nodule, preoperative serum carbohydrate antigen 125, and the number of lymph node metastases were found to influence distant metastasis-free survival after radical gastrectomy in elderly patients(all P<0.05).The multifactorial analysis also indicated that tumour outgrowth grade was an important independent prognostic factor for postoperative distant metastasis in elderly gastric cancer patients( HR=3.731, P<0.001). Conclusions:The findings of this study indicate that tumor budding may serve as a potential marker for predicting distant organ metastasis in elderly patients who have undergone radical gastrectomy.This discovery holds significant clinical implications.

Schizophrenia is a chronic disabling disease of unknown etiology. Its neuroimaging abnormalities have been confirmed by a large number of studies. However, when these structural abnormalities occur and how they develop over time are unclear. The relationship between structural abnormalities and antipsychotic treatment needs to be further explored. Longitudinal studies on the brain structure of clinical high risk for psychosis, first-episode schizophrenia and chronic schizophrenia, exploring the influence of drug therapy on them, are helpful to construct the trajectories of brain structure changes in the whole course of schizophrenia and dynamically track the brain structure changes, so as to further explore the pathophysiology of schizophrenia. This article reviews the longitudinal research progress of brain structure changes in patients with schizophrenia.

This study aimed to investigate the ameliorative effects of 60% ethanol elution fraction (ESMW) from Si Miao Wan on the hepatic lipid accumulation and its mechanism.TG kit, BODIPY fluorescence staining, QPCR, WB, oil red O staining, and AMPKα knockdown were used to detect the ability of ESMW to improve lipid accumulation in hepatocytes stimulated with free fatty acid.Furthermore, the effects of ESMW on the oral glucose tolerance, serum biochemical indexes, TG content in liver tissue, the expressions of mRNA and protein related to lipid metabolism in liver tissue were studied in mice fed with high fat diet to verify the mechanism of ESMW fraction on hepatic lipid accumulation.The results showed that ESMW inhibited lipid accumulation induced by free fatty acids by regulating AMPK signaling pathway, and that ESMW significantly improved the lipid metabolism of mice fed with high fat diet, with relation to AMPK signaling pathway.

Medical ethics education in clinical practice stage is especially critical to improve medical students' humanistic, medical ethics and professional accomplishment. Compared with other clinical disciplines, dermatology and venereology has many characteristics. To strengthen medical ethics education in dermatology and venereology clinical practice, we should persist in promoting and cultivating core values of Chinese socialism, accurately grasp the characteristics of various skin diseases, educate and guide students to flexibly apply the basic principles of ethics and improve their ethical decision-making ability. In the process of teaching implementation, we should pay attention to the coordination of education, enrich teaching means and strengthen practical teaching, so as to improve the quality of education.

Objective: To investigate the effect of AKT1 deSUMOylation induced by Ubc9 silencing on the proliferation and metastasis of hepatocellular carcinoma (HCC) cells. Methods: The Ubc9 gene was silenced using RNA interference, and the expression levels of Ubc9, SUMO1 and AKT1 protein were detected by Western blot. Cell proliferation and cell cycle was analyzed by MTT and flow cytometry. Wound healing and transwell assays were used to detect the cell migration ability. Furthermore, the xenograft model was established, and tumor growth curves were drawn. The in situ apoptotic rates was measured using TUNEL Apoptosis Assay. The expression of proliferating cell nuclear antigen (PCNA), matrix metalloproteinase (MMP)-2 and MMP-9 were evaluated by immunohistochemical staining. Results: Knockdown of Ubc9 gene significantly decreased the protein expression levels of Ubc9, conjugated SUMO1, free SUMO1 and AKT1 in HCC cells (P<0.05 for all). In control, siR-neg and siR-Ubc9 groups, the cell proliferation indexes were 53.19%, 54.25% and 39.17%, respectively. Moreover, cell migration distance and migrating cells per low power field for all these three groups were (59.47±4.66) μm and 89.44±8.36, (56.56±5.37) μm and 93.84±8.79, as well as (34.57±6.61) μm and 41.67±5.39, respectively. In the xenograft model, the weights of subcutaneous tumors for these three groups were (3.78±0.69) g, (3.72±0.72) g and (2.09±0.61) g, respectively. The corresponding apoptotic cell rates were (7.79±2.21)%, (6.45±2.48)% and (33.59±5.44)%, respectively. The expression levels of PCNA, MMP-2 and MMP-9 protein were significantly decreased in siR-Ubc9 group (P<0.05). Conclusions Ubc9 silencing in HCC cells induces AKT1 deSUMOylation, and then inhibits the proliferation and metastasis. These results provide a new therapeutic strategy for liver cancer in the future.

Cardiovascular risk and related medical burden due to influenza in patients with chronic disease were higher than those of healthy subjects. As a result, influenza vaccination is recommended as a strategy for secondary prevention in cardiovascular disease by major cardiovascular organizations, but the prevalence of influenza vaccination in these population is still low. Whether influenza vaccine can prevent cardiovascular events such as myocardial infarction and death is still controversial based on current evidences from observational studies and case-control studies, which may result from study desion,subjects selection,outcome definition and sample size issues. Recent meta-analysis showed that influenza vaccination may reduce cardiovascular risk, but large-scale random controlled trials with adequately power should be conducted to confirm these findings as well as the target population for this strategy further.
