ABSTRACT
Objective:To investigate the clinical characteristics and risk factors of alcoholic liver disease (ALD) combined with type 2 diabetes mellitus (T2DM).Methods:The clinical data of 70 patients with ALD combined with T2DM (ALD + T2DM group) who received treatment from March 2015 to March 2020 in the First Affiliated Hospital of Guangxi Medical University were retrospectively analyzed. The clinical data of 69 patients with ALD (ALD group) and 69 patients with T2DM (T2DM group) who concurrently received treatment were also analyzed. Sex, age, body mass index, drinking habits and other basic information in the three groups were collected. The risk factors of ALD combined with T2DM were evaluated by logistic regression analysis.Results:The daily alcohol intake and years of drinking in the ALD + T2DM group were (110.97 ± 79.78) g/d and (25.17 ± 10.05) years, respectively, which were significantly higher than (91.48 ± 64.26) g/d and (21.78 ± 8.91) years respectively in the ALD group ( t = 1.699, 2.102, both P < 0.05). The incidence of metabolic syndrome in the ALD + T2DM group was 34.3% (24/70), which was significantly higher than 15.9% (11/69) in the ALD group ( χ2 = 6.210, P < 0.05). The activity ratio of aspartate aminotransferase/alanine aminotransferase, total bilirubin level, gamma glutamyl transpeptidase activity in the ALD + T2DM group were 1.59 ± 0.93, (64.73 ± 39.90) μmol/L, (522.93 ± 353.66) U/L, respectively, which were significantly higher than (1.04 ± 0.53), (10.37 ± 4.51) μmol/L, (35.73 ± 23.99) U/L, respectively in the T2DM group ( t = 4.280, 3.780, 5.045, all P < 0.05). Triacylglycerol level in the ALD + T2DM group was significantly higher than that in the ALD group [(1.69 ± 1.04) mmol/L vs. (1.28 ± 0.87) mmol/L, t = 2.523, P < 0.05). Prothrombin time and lactate dehydrogenase activity in the ALD + T2DM group were (13.13 ± 2.79) s and (226.17 ± 79.93) U/L, respectively, which were significantly higher than (10.41 ± 0.84) s, (172.63 ± 39.34) U/L, respectively in the T2DM group ( t = 7.715, 4.969, both P < 0.05). Multivariate Logistic regression analysis showed that prothrombin time, triacylglycerol level, years of drinking, gamma glutamyl transpeptidase activity, and amount of drinking were the main risk factors for ALD combined with T2DM ( OR = 2.010, 3.270, 1.230, 1.060, 1.006, all P < 0.05). Conclusion:Patients with ALD combined with T2DM are prone to metabolic syndrome and lipid disorders, which may aggravate the disease. Prothrombin time, triacylglycerol level, years of drinking play an important role in the development of ALD combined with T2DM.
ABSTRACT
Autophagy is a special cellular process, which can participate in regulating cell survival, growth, differentiation and homeostasis maintenance by transporting damaged organelles and macromolecular substances to lysosomes for degradation. Autophagy plays a very important role in all aspects of life process. Research results show that autophagy plays an important role in tumor occurrence, development and metastasis. The synergistic effect of autophagy and vascular endothelial growth factor promotes tumor angiogenesis and cell repair, and may play an important role in the development of tumor resistance to anti-vascular drug therapy. Targeted therapy with autophagy as the target may be a new direction for anti-tumor molecular targeted therapy in the future, aiming to provide multi-target collaborative therapy to benefit patients.
ABSTRACT
The activation of p21 kinase 2 (PAK2) has a certain value in cancer research, since its participation in a series of intracellular biological activities. There is a relatively little research on its relationship with the development of tumors. PAK2 can be activated by a variety of upstream signals, especially small G protein Rho family of Rac and Cdc42, and it participates in a variety of important signaling pathways and cell function regulation. Abnormal expression of PAK 2 has been reported in various tumors, which involves in cytoskeletal remodeling, cell motility, apoptosis, signal transduction, gene transcription, translation and angiogenesis. Therefore, PAK2 plays an important role in tumor occurrence and development. The study on PAK2 and the targeting therapy for anti-PAK2 provides a new sight on the treatment and prevention of tumor.
ABSTRACT
Objective To evaluate the diagnostic value of the cell block (CB) with immunostaining method by endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) biopsy for pancreatic lesions.Methods A total of 72 patients with pancreatic lesions underwent EUS-FNA at the First Affiliated Hospital of Guangxi Medical University from March 2012 to June 2013.The EUS-FNA samples of all patients were processed by conventional smear cytology,liquid-based cytology (LBC) and the cell block with immunostaining.Results There were 61 pancreatic patients who were finally diagnosed as having pancreatic tumors,including 55 cases of pancreatic cancer,2 pancreatic solid pseudopapillary tumor,4 pancreatic endocrine tumors (PETs),and 11 benign lesions:4 chronic pancreatitis,2 pancreatic tuberculosis,4 pancreatitis and 1 pancreatic mucinous cystadenoma.The diagnostic sensitivity of conventional smear cytology,liquid-based cytology and cell block with immuno-staining method were 68.9％ (42/61),75.4％ (46/61) and 90.2％ (55/61),respectively.The diagnostic specificity of three methods were all 100.0％.The diagnostic accuracy rates were 73.6％ (53/72),79.2％ (57/72) and 91.7％ (66/72),respectively.The diagnostic accuracy rate of the cell block with immunostaining was higher than those of conventional smear cytology (P ＜ 0.05) and the liquid-based cytology (P ＜ 0.05).Conclusion Endoscopic ultrasound-guided fine-needle aspiration is a safe and effective method with high sensitivity and specificity in the diagnosis of pancreatic lesions.Cell block method combining immunohistochemistry helps to increase the diagnosis and histological diagnosis of pancreatic lesions.The cell block has a greater clinical value in the diagnosis of pancreatic lesions.
