Objective To investigate the relationship between blood vessel invasion (BVI) and clinicopathologic features and prognosis in patients with gastric cancer,and analyze related factors affecting the prognosis of patients.Methods The clinicopathological data of 206 patients with gastric cancer who were admitted to the Nanjing Hospital Affiliated to Nanjing Medical University from January 2007 to December 2010 were retrospectively analyzed.The BVI of surgical tumor specimens in all patients was detected by immunohistochemical staininng.All the patients were followed up via outpatient examination and telephone interview up to March 2014.The count data were analyzed using the chi-square test.The survival curve was drawn by Kaplan-Meier method.The survival analysis and univariate analysis were done using the Log-rank test,and multivariate analysis was done using the COX regression model.Results The BVI rate of 206 patients was 27.67％ (57/206).The BVI rate of tumor tissues,tumor differentiation,perineural invasion,T stage,N stage and TNM stage in all patients with gastric cancer were compared,showing significant differences (x2=14.396,9.569,15.579,43.453,30.732,P ＜ 0.05).After operation,188 patients were followed up for 6.0-60.0 months (median,34.0 months),with the follow-up rate of 91.26％ (188/206).Among 188 patients with follow-up,the median survival time and 5-year cumulative survival rate in patients with BVI and with negative BVI were 32.4 months and 19.6％,40.7 months and 42.0％,respectively,with a significant difference in the survival of patients (x2 =9.364,P ＜ 0.05).The results of univariate analysis showed that the diameter of tumor,tumor differentiation,perineural invasion,BVI,T stage,N stage and TNM stage were factors affecting the prognosis of patients with gastric cancer (x2=9.241,17.486,11.243,9.364,27.666,216.745,49.887,P ＜ 0.05).The results of multivariate analysis showed that the diameter of tumormore than 5 cm,BVI,stage T4,stage N3 and stage Ⅲ were independent risk factors affecting the prognosis of patients with gastric cancer (HR =0.502,0.456,0.052,0.001,0.735; 95％ confidence interval:0.334-0.754,0.289-0.720,0.004-0.664,0.000-0.006,0.159-3.398,P ＜ 0.05).Conclusions BVI in patients with gastric cancer is associated with the progression of tumors.The diameter of tumor more than 5cm,BVI,stage T4,stage N3 and stage Ⅲ are independent risk factors affecting the prognosis of patients with gastric cancer,and BVI may be a predictor of poor prognosis of patients with gastric cancer.

Objective To explore the potential genetic variants related with late-onset Alzheimer's disease(LOAD),and to broaden the AD genetic susceptibility factor profile.Methods We targetedly sequenced four lipids metabolism related genes including apolipoprotein E(APOE),sortilin-related receptor gene (SORL 1),apolipoprotein C-I (APOC1) and clusterin (CLU),validated these candidate variants in patients with LOAD and mild cognitive impairment (MCI)and the controls with normal cognitive function,and made a bioinformatic analysis.Results The mutation in the allele of CLU rs117389184,a low-frequency single nucleotide polymorphism,would increase the risk of LOAD and MCI[OR (95 ％ CI):3.56 (1.08-4.84),P =0.026;OR (95 ％ CI):3.06 (0.98-4.03),P =0.026],suggesting CLU rs117389184 gene variant was associated with cognitive impairment.This variation could affect CLU gene expression by interfering with the binding of transcription factors.Conclusions CLU rs117389184 is a new genetic risk variant for LOAD and MCI.

Edema， as a common pathological phenomenon， is essentially the abnormal accumulation of body fluids in the interstitial spaces of human tissues and is often a direct manifestation of various underlying diseases， such as heart failure， impaired renal filtration function， or liver metabolic disorders. In the Western medical system， strategies for treating edema primarily focus on the use of diuretics to promote the excretion of excess fluid in the body， while simultaneously addressing the underlying causes through targeted treatment. However， long-term reliance on the use of diuretics may lead to a decrease in drug sensitivity and induce side effects， including electrolyte disorders such as hypokalemia and hypercalcemia， posing a potential threat to patients' overall health. Compared with Western medicine， traditional Chinese medicine （TCM） has demonstrated well-recognized and sustained efficacy in treating edema with its unique theoretical system. Zhulingtang， as a classic and commonly used TCM formula， is widely applied as it can effectively relieve edema and related symptoms. In recent years， ongoing in-depth studies on the treatment of edema with Zhulingtang have revealed multiple mechanisms of action of Zhulingtang， including the regulation of water metabolism and the reduction of inflammatory responses， thereby providing a solid theoretical basis for clinical practice. This review summarized the research progress on the treatment of edema with Zhulingtang in recent years and analyzed the active ingredients and action pathways of Zhulingtang. Additionally， the primary mechanisms of action and efficacy were systematically analyzed， so as to provide references for the clinical application of Zhulingtang in treating various types of edema， such as cardiogenic edema， renal edema， and hepatogenic edema. This review aims to offer theoretical support and practical guidance for clinicians in deciding treatment approaches， as well as references for subsequent in-depth studies， thereby promoting further development of TCM in the treatment of edema.
