Clinical Effect of Alanyl Glutamine Combined with Octreotide on Severe Acute Pancreatitis / 现代生物医学进展

Objective:To explore the clinical efficacy of alanyl glutamine (Ala-Gln) combined with octreotide in the treatment of severe acute pancreatitis (SAP) and its effects on the serum interleukin-6 (IL-6),C reactive protein (CRP) levels and related biochemical parameters.Methods:100 cases of patients with SAP in our hospital from January 2013 to December 2016 were selected and randomly divided into two groups.The control group was treated by octreotide,while the observation group was treated by Ala-Gln combined with octreotide.The clinical effect,changes of serum IL-6,CRP,amylase (AMY),lactate dehydrogenase (LDH),prealbumin (PA) and albumin (ALB) levels before and after therapy were compared between two groups.Results:On the 10th day after treatment,the overall effective rate of observation group was 88.0％ which was significantly higher than that of the control group (64.0％,P＜0.05).The serum IL-6,CRP,AMY and LDH levels of both groups on the 10th day after treatment were significantly lower than those before treatment (P＜0.01).Compared with the control group,the improvement of serum IL-6,CRP,AMY,LDH levels of observation group were more significant(P＜0.01).Compared with those before treatment,the serum PA and ALB levels of both groups were significantly increased on the 10th day after treatment(P＜0.05),and the improvement of serum PA and ALB levels of observation group on the 10th day after treatment were significantly better than those of the control group(P＜0.01).Conclusion:Alanyl glutamine combined with octreotide could effectively eliminate or alleviate the symptoms and signs of patients with severe acute pancreatitis,control the inflammatory reaction,improve the level of metabolism,improve the prognosis.

Quercetin suppresses lung cancer growth by targeting Aurora B kinase.

aurora B kinase is highly expressed in several cancer cells and promotes tumorigenesis and progression, and therefore, it is an important target for drug to treat tumors. Quercetin was identified to be an antitumor agent. Herein, we report for the first time that quercetin inhibited aurora B activities by directly binding with aurora B in vitro and in vivo. Ex vivo studies showed that quercetin inhibited aurora B activities in JB6 Cl41 cells and A549 lung cancer cells. Moreover, knockdown of aurora B in A549 cells decreased their sensitivities to quercetin. In vivo study demonstrated that injection of quercetin in A549 tumor-bearing mice effectively suppressed cancer growth. The phosphorylation of histone 3 in tumor tissues was also decreased after quercetin treatment. In short, quercetin can suppress growth of lung cancer cells as an aurora B inhibitor both in vitro and in vivo.

Effectiveness research on ultrasonic rapid paraffin section in the clinical application of intraoperative diagnosis of breast tumor / 中国医师进修杂志

Objective To investigate the clinical application value of ultrasonic rapid paraffin section in intraoperative diagnosis of breast tumor.Methods Twenty-five patients of breast tumor specimens were admitted from December 2012 to December 2013,including 19 cases from surgery,4 cases from gynecology,2 cases from medical patients.Twenty-five cases were used with ultrasonic rapid paraffin section and the remaining tissues were used as conventional paraffin section,then compared the two methods.Results This study took two different ways but the same results were achieved with 23 cases,the diagnostic accuracy was 92.0％ (23/25).Two of 25 cases were misdiagnosed with the misdiagnosis rate was 8.0％ (2/25).One patient appeared delayed diagnosis,accounting for 4.0％(1/25).After 25 cases of breast cancer biopsy treated with ultrasonic rapid paraffin section,benign lesions was 20 patients,with the highest incidence of breast adenosis of 9 cases (36.0％,9/25).The malignant lesions was 4 patients with invasive ductal carcinoma in which the highest incidence,accounting for 3 cases (12.0％,3/25).Delay diagnosed 1 case of intraductal papilloma.Conclusion Ultrasonic rapid parafifin section is widely used in clinical application,with high quality and diagnostic biopsy rate and other characteristics,so it is worthy of clinical application.
