RESUMO
The aim of this research is to explore the therapeutic efficacy of platelet-rich plasma (PRP) on the cutaneous ulceration of diabetes mellitus (DM). From the beginning of the database until January 2024, we looked through several databases to obtain randomised, controlled PRP studies to treat the wound healing of DM in adult patients. The Cochrane Collaboration's Risk-Of-Bias Instrument was used to evaluate the risk of bias in randomised, controlled studies. Funnel plots, sensitivity analyses and Egger regression tests were employed to determine the reliability and effectiveness of the meta-analyses. Depending on the degree of heterogeneity, a fixed or random effect model has been used. The statistical significance was determined to be below 0.05. Altogether 281 trials were collected from the database and entered into Endnote Software for screening, and 15 trials were analysed. It was found that PRP was associated with a higher rate of wound healing (OR, 3.23; 95% CI, 2.42, 4.31 p < 0.0001). PRP was associated with a reduction in the risk of post-operative wound infection (OR, 0.46; 95% CI, 0.21, 0.99 p = 0.05). PRP was associated with a reduction in the risk of amputations amongst those with DM (OR, 0.50; 95% CI, 0.30, 0.84 p = 0.009). Overall, PRP treatment for DM is expected to improve the rate of wound healing, decrease the risk of wound infection and decrease the risk of amputations.

Primary malignant melanoma of the gallbladder is an extremely rare tumor with approximately 39 cases described in the literature so far. However, since the first case was reported in 1907, it remains controversial whether gallbladder involvement in malignant melanoma is primary or metastatic. Here, we report a case of primary malignant melanoma of the gallbladder. A 52-year-old male presented to the emergency department with right upper quadrant abdominal pain and was found to have tumefactive sludge filling the majority of the gallbladder with possible gallbladder wall thickening on ultrasonography. A laparoscopic cholecystectomy was performed for presumed acute cholecystitis. Histopathologic examination of the gallbladder revealed malignant melanoma arising from the mucosa of the gallbladder. Further clinical investigation excluded other primary sites, supporting a diagnosis of primary malignant melanoma of the gallbladder.
RESUMO
Background: Breast cancer (BC) is a malignancy that is inadequately treated and poses a significant global health threat to females. The aberrant expression of long noncoding RNAs (lncRNAs) acts as a complex with a precise regulatory role in BC progression. LINC00969 has been linked to pyroptotic cell death and resistance to gefitinib in lung cancer cells. However, the precise function and regulatory mechanisms of LINC00969 in BC remain largely unexplored. Methods: Cell proliferation, migration, and invasion of BC cells were evaluated using CCK-8 and Transwell assays. Western blotting was employed to analyze the protein expression levels of HOXD8, ILP2, PI3K, t-AKT, and p-AKT. Results: LINC00969 was drastically reduced in BC tissues LINC00969 overexpression markedly suppressed proliferation, migration, and invasion, and blocked PI3K and p-AKT protein expression in MCF-7 cells. Activation of the PI3K/AKT pathway reversed the suppressive effect of LINC0096 overexpression on the proliferation, migration, and invasion of MCF-7 cells. Moreover, LINC00969 overexpression enhanced HOXD8 and blocked ILP2 protein expression in MCF-7 cells. In contrast, activating the PI3K/AKT pathway had no effect on HOXD8 and blocked ILP2 protein expression in MCF-7 cells overexpressing LINC00969. HOXD8 knockdown enhanced ILP2, PI3K, and p-AKT protein expression, and the proliferation, migration, and invasion of MCF-7 cells co-transfected with si-HOXD8 and ov-LINC00969. LINC00969 regulated HOXD8 via binding to miR-425-5p. Conclusion: LINC00969 inhibits the proliferation and metastasis of BC cells by regulating PI3K/AKT phosphorylation through HOXD8/ILP2.
