ObjectiveTo investigate the expression level of mammalian sterile 20-like kinase 1 （MST1） in prostate cancer （PCa） tissues， its biological functions， and its regulatory effects on androgen receptor （AR） and vascular endothelial growth factor （VEGF） expression. MethodsImmunohistochemistry was performed to detect MST1 expression in 77 prostate cancer tissues and 34 benign prostatic hyperplasia （BPH） tissues， and the relationship between MST1 expression and clinicopathological parameters was analyzed. MST1-overexpressing C4-2 and LNCaP cell lines were constructed. CCK-8 assay， Transwell migration assay， and angiogenesis assay were conducted to evaluate the effects of MST1 on cell proliferation， migration， and angiogenesis. The expression changes of AR and VEGF were detected by qRT-PCR and Western blot. ResultsMST1 expression was significantly lower in PCa tissues compared with BPH tissues （P=0.012）. Low MST1 expression was significantly associated with tumor metastasis （P=0.033）. MST1 overexpression inhibited C4-2 cell proliferation and migration， with transmembrane migrated cells reduced by 53.6% （P<0.01）. MST1 overexpression decreased the mRNA and protein expression levels of AR and VEGF （P<0.05）. Angiogenesis assay demonstrated that the length of new vessel structure was significantly reduced （P<0.05）. ConclusionMST1 shows a low expression level in PCa tissues and is associated with tumor metastasis. MST1 exerts tumor-suppressive effects in prostate cancer by inhibiting cell proliferation， migration， and angiogenesis， as well as downregulating the expression of AR and VEGF， indicating its potential as a therapeutic target for prostate cancer.

Diabetes of the exocrine pancreas(DEP) refers to a complication of diseases of the exocrine pancreas, associated with an increased risk of pancreatic cancer. Recent evidence has indicated that DEP, after type 2 diabetes, has become the second most common type of adults-onset diabetes, with a higher prevalence than type 1 diabetes. DEP is not a single condition but encompasses various exocrine pancreatic disorders that lead to hyperglycemia through different mechanisms, creating significant diagnostic and therapeutic challenges. This review examines the latest research on the risk factors and pathogenesis of DEP, aiming to provide insights to improve its clinical management strategies.

Objective:To investigate the relationship between the level of angiotensin Ⅱ type 1 receptor autoantibody (AT1-AA) in the uterine fluid and the thickness of endometrium in infertile women with chronic endometritis.Methods:A case-control study was conducted to select 122 patients who underwent hysteroscopy and endometrial tissue biopsy at Assisted Reproduction Center, Taiyuan Central Hospital due to infertility from March 2023 to January 2024 as the study subjects. According to the results of hysteroscopy and endometrial tissue biopsy, the patients were divided into 52 cases in the infertility group with normal endometrium (NE infertility group) and the chronic endometritis combined with infertility group (CE infertility group) with 70 cases. Enzyme-linked immunosorbent assay was used to detect the level of AT1-AA in uterine fluid of the two groups. General clinical data, AT1-AA absorbance value of uterine fluid and uterine related indexes of the two groups were analyzed, and the correlations between AT1-AA level and the variation of indexes were analyzed.Results:Gravidity (median: 1 vs 1; Z=7.029, P=0.030) and parity (median: 0 vs 0; Z=12.258, P=0.002) in CE infertility group were higher than those in NE infertility group. There was AT1-AA in the uterine fluid, and the level of AT1-AA in CE infertility group was significantly higher than that in NE infertility group (median: 2.07 vs 1.44; Z=3.099, P=0.029). The endometrial thickness of CE infertility group was lower than that of NE infertility group (median: 6.0 vs 7.0 mm; Z=-2.179, P=0.029), and there were no statistical differences in other indexes between the two groups (all P>0.05). Further correlation analysis showed that there were no correlation between the level of AT1-AA in uterine fluid and parity, endometrial thickness, gravidity in NE infertility group (all P>0.05). However, the level of AT1-AA in uterine fluid of CE infertility group was positively correlated with parity (Spearman′s r=0.339, P=0.004), and negatively correlated with endometrial thickness (Spearman′s r=-0.499, P<0.001), but not correlated with gravidity ( P>0.05). Conclusions:AT1-AA is present in the uterine fluid of infertile women. The elevated level of AT1-AA in uterine fluid of infertile women with CE is related to the thinning of the endometrium.

Objective To investigate the value of electrocardiogra(ECG)P-wave parameters com-bined with serum adiponectin and visfatin(VF)in predicting recurrence of atrial fibrillation(AF)after radiofrequency ablation.Methods A total of 120 AF patients(AF group)admitted to our hospital from March 2021 to March 2023 were enrolled,and divided into a recurrence group(39 cases)and a non-recurrence group(81 cases)according to the postoperative condition.Another 120 healthy individuals who took physical examination in the same period were enrolled and served as control group.All subjects underwent ECG.ELISA was used to detect adiponectin and VF levels.Logistic regression analysis was used to identify the influencing factors of postoperative recur-rence in AF patients.ROC curve was plotted to analyze the predictive value of P-wave parameters combined with serum adiponectin and VF for postoperative recurrence in AF patients.The P-wave parameters included P-wave duration(PWD),maximum PWD(Pmax),minimum PWD,and P-wave dispersion(Pd).Results PWD,Pmax and Pd were significantly decreased in AF patients after operation(P＜0.01).Serum adiponectin level was obviously lower and that of VF was nota-bly higher in the AF group than the control group(6.15±1.58 μg/L vs 11.43±2.26 μg/L,12.05±2.30 μg/L vs 6.23±1.02 μg/L,P＜0.01).The recurrence group had remarkably higher preopera-tive PWD,Pmax and Pd,and lower adiponectin and higher VF levels than the non-recurrence group(P＜0.01).Multivariate logistic regression analysis showed that PWD,Pmax,Pd,and VF were risk factors,and adiponectin was a protective factor for postoperative recurrence in AF pa-tients(P＜0.05,P＜0.01).ROC curve analysis indicated that PWD,Pmax,Pd,adiponectin and VF combined together to detect postoperative recurrence in AF patients had an AUC value of 0.972,which was higher than that of above indicators alone(Z=2.574,Z=2.567,Z=2.543,Z=2.554,Z=2.586,P＜0.05).Conclusion ECG P-wave parameters as well as elevated serum VF and re-duced serum adiponectin are influencing factors for postoperative recurrence in AF patients,and their combined detection may promote the predictive value for postoperative recurrence in them.
