Retrospective Investigation and Research on Fall Events Among Hospitalized Patients in the Rehabilitation Department.

Objective: We investigated the clinical characteristics, fall outcomes, and related factors of falls in patients who were hospitalized in the rehabilitation department, and explored strategies to reduce the incidence of falls and prevent falls in patients. Methods: Data from 60 patients who fell in the rehabilitation department between 2016 and 2021 were analyzed for clinical characteristics, associated factors, incidence of falls, injuries, and patient demographics. Under the random stratified sampling method, 60 patients who did not fall during the same period were selected as the control group, and relevant data was collected. Measurement data were compared using an independent sample t-test. Enumeration data were compared using chi-squared (χ2) test was employed to compare these data between the two groups. Non-parametric data were analyzed using the Mann-Whitney U-test. Factors potentially influencing falls were scrutinized through both univariate and binary logistic regression analyses. Results: The median annual incidence of falls among patients who were hospitalized in the rehabilitation department was 0.04%, while the overall fall injury rate was 60%. Falls were most prevalent within 30 days of hospitalization (71.67%). The most common fall-related condition was craniocerebral disease (83.33%). The incidents of falls location of fall were mainly reported in nearby areas of rehabilitation ward (70%). Most accidents occurred between 7:00 a.m.-12:00 p.m. and 3:01 p.m.-6:00 p.m. (63.33%), and dyskinesia was the most common cause of falls (71.67%). There were 39 patients (65.00%) with Barthel Index (BI) scores ranging between 40-60. Conclusion: Patients in the rehabilitation department had a greater incidence of falls and fall injuries. Within 30 days of admission, patients with moderately dependent craniocerebral disorders and dyskinesia frequently experienced falls during typical daytime shifts in areas characterized by endemic conditions.

A correlation study between prostate necrosis rate calculated by 3D Slicer software and clinical efficacy of prostatic artery embolization, along with an analysis of predictors of clinical success after prostatic artery embolization.

PURPOSE: To analyze the correlation between the prostate necrosis rate at 1-month after prostatic artery embolization (PAE) and the clinical efficacy at 1-year after PAE, and to explore potential predictors of clinical success after PAE for the treatment of lower urinary tract symptoms secondary to benign prostatic hyperplasia (BPH). METHODS: The prostate magnetic resonance imaging data at 1-month after PAE were imported into 3D Slicer software for calculating the prostate necrosis rate and thus analyzing the relationship between the prostate necrosis rate at 1-month after PAE and the efficacy score ratio at 1-year after PAE. The 151 patients with PAE technical success were divided into a clinical success group (n = 126) and a clinical failure group (n = 25). Independent predictors of clinical success after PAE were analyzed by multifactorial logistic regression, and the predictive performance of each factor was evaluated by applying the receiver operating characteristic curve and the area under the curve (AUC). RESULTS: There was a linear negative correlation between the prostate necrosis rate at 1-month after PAE and the efficacy score ratio at 1-year after surgery (P < 0.001). In the clinical success group, both the initial prostate volume (PV) and the prostate necrosis rate at 1-month after PAE were significantly higher than in the clinical failure group (P < 0.001), and acute urinary retention (AUR) and adenomatous-dominant BPH were also associated with clinical success (P < 0.05). Multifactorial logistic regression analysis revealed that larger initial PV, a higher prostate necrosis rate at 1-month after surgery, and AUR were independent predictors of clinical success after PAE. The AUC values for these three indicators and their combination were 0.720, 0.928, 0.599, and 0.951, respectively, in which the prostate necrosis rate at 1-month after PAE demonstrating a high predictive value. CONCLUSION: The higher the prostate necrosis rate at 1-month after PAE, the better the clinical efficacy at 1-year after PAE is likely to be, and the prostate necrosis rate at 1-month after PAE is expected to become a predictor of clinical success after PAE.

Cavernous lymphangioma of the urinary bladder in an adult woman: an additional case report of a rare lesion and literature review.

BACKGROUND: Urinary bladder lymphangioma is a rare and benign lesion that is often causes symptoms related to irritation and urinary tract obstruction. Because a lymphangioma may resemble a true neoplasm of the urinary bladder clinically, the lesion must be removed for accurate histologic diagnosis and to rule out malignancy. CASE PRESENTATION: We present a case of a 40-year-old female who was evaluated for painless gross hematuria. Clinical and diagnostic work up revealed a sharply defined mass involving the wall and bulging into the cavity on the dome of the bladder. Partial cystectomy was performed and histologic findings were compatible with cavernous lymphangioma. The symptom of hematuria relieved after the procedure and the patient was in good status without evidence of recurrence by cystoscopy at follow-up 6 months later. CONCLUSIONS: Lymphangioma of the urinary bladder is treated with surgical excision and seems to have no recurrence once completely resected, but long-time follow-up may be needed.

Notch3 inhibits epithelial-mesenchymal transition in breast cancer via a novel mechanism, upregulation of GATA-3 expression.

Notch3 and GATA binding protein 3 (GATA-3) have been, individually, shown to maintain luminal phenotype and inhibit epithelial-mesenchymal transition (EMT) in breast cancers. In the present study, we report that Notch3 expression positively correlates with that of GATA-3, and both are associated with estrogen receptor-α (ERα) expression in breast cancer cells. We demonstrate in vitro and in vivo that Notch3 suppressed EMT and breast cancer metastasis by activating GATA-3 transcription. Furthermore, Notch3 knockdown downregulated GATA-3 and promoted EMT; while overexpression of Notch3 intracellular domain upregulated GATA-3 and inhibited EMT, leading to a suppression of metastasis in vivo. Moreover, inhibition or overexpression of GATA-3 partially reversed EMT or mesenchymal-epithelial transition induced by Notch3 alterations. In breast cancer patients, high GATA-3 expression is associated with higher Notch3 expression and lower lymph node metastasis, especially for hormone receptor (HR) positive cancers. Herein, we demonstrate a novel mechanism whereby Notch3 inhibit EMT by transcriptionally upregulating GATA-3 expression, at least in part, leading to the suppression of cancer metastasis in breast cancers. Our findings expand our current knowledge on Notch3 and GATA-3's roles in breast cancer metastasis.

Influence of the total saponin fraction from Dioscorea nipponica Makino on TLR2/4-IL1R receptor singnal pathway in rats of gouty arthritis.

ETHNOPHARMACOLOGICAL RELEVANCE: Dioscorea nipponica Makino have been extensively used in traditional medicine for the treatment of arthritic diseases, particularly gouty arthritis (GA). MATERIALS AND METHODS: Sixty male Wistar rats were divided into six groups: the normal group, model group, colchicine group (COL) and three total saponin groups (RDN) (high dose [160mg/kg], middle dose [80mg/kg] and low dose [40mg/kg]). The mRNA and protein expression levels of TLR2, TLR4, IRAK1, TRAF6, TAK1, IKKα, IκBα and NF-κB in the synovial tissue of joint were detected by realtime PCR and WB methods respectively. The contents of IL-1ß, IL-6 and TNF-α in the blood serum were measured by Elisa method. The activation of NF-κB was measured by EMSA method. RESULTS: Our study showed that RDN decreased both the mRNA and protein expressions of TLR2, TLR4, IRAK1, TRAF6, TAK1, IKKα, IκBα and NF-κB of the synovial tissue of joint of rats induced with monosodium urate crystal (MSU). They could also reduce the levels of IL-1ß, IL-6 and TNF-α in the blood serum. Further, EMSA results showed that RDN reduced the DNA binding ability of NF-κB p65 of model group. CONCLUSION: RDN has the effect of anti-inflammation in MSU-induced GA model. This is realised by influencing an important inflammatory signal pathway which is called TLR2/4-IL1R receptor signal pathway. It highlights the potential utility of RDN for the management of GA.

[Down-regulation of vascular endothelial growth factor expression in ovarian cancer cell line SKOV3 by interferon-gamma].

OBJECTIVE: To determine whether interferon-gamma (IFN-gamma)inhibit the expression of vascular endothelial growth factor (VEGF) in ovarian cancer cell line SKOV3 with the level of mRNA and protein. METHODS: Cultured SKOV3 was treated by IFN-gamma with different concentration and time. The morphological changes of SKOV3 treated by IFN-gamma through microscope and proliferation by methyl thiazolyl tetrazolium (MTT). The expression of VEGF mRNA in SKOV3 culture was determined by relative quantitative reverse-transcription polymerase chain reaction. The VEGF protein level in supernatants was determined by enzyme-linked immunosorbent assay (ELISA) and in cytoplasma by immunocytochemical staining. RESULTS: There is a small changes in shape on SKOV3, but no alter of cell proliferation during treating with different concentration and time. Expression of VEGF mRNA and protein decreased with the INF-gamma concentration increasement, but no time-effect pattern exist. The effect peak appeared when the concentration was 1,000 U/ml. CONCLUSION: IFN-gamma can inhibit the expression of VEGF in ovarian cancer cell line SKOV3 with the level of mRNA and protein.
