Combined detection of MLNR and serum CEA in predicting preoperative distant metastasis of stage Ⅱ-Ⅲ colon cancer / 中华普通外科杂志

Objective To investigate the predictive value of metastatic lymph node ratio (MLNR) combined with preoperative serum carcinoembryonic antigen (CEA) in the detection of distant metastasis of stage Ⅱ-Ⅲ colon cancer after radical resection.Methods A retrospective study was performed on the clinical data of 325 patients with stage Ⅱ-Ⅲ colon cancer undergoing radical resection in the Second Hospital of Lanzhou University from Jan 2010 to Jan 2015.Results MLNR was correlated with the maximum diameter of tumors,the degree of differentiation of tumors,clinical TNM stage and distant metastasis (P ＜ 0.05),serum CEA was correlated with the maximum diameter of tumors,clinical TNM stage,nerve or vascular invasion and distant metastasis (P ＜ 0.05).Logistic regression analysis showed that low differentiation of tumor tissue,TNM Ⅲ stage,high MLNR and high serum CEA were independent risk factors for distant metastasis of colon cancer after radical operation.Conclusions The combined detection of MLNR and serum CEA has a good predictive value for distant metastasis with stage Ⅱ-Ⅲ colon cancer.

Role of probiotics in treatment of nonalcoholic fatty liver disease / 中华肝脏病杂志

Nonalcoholic fatty liver disease (NAFLD) is one of the most common chronic liver diseases in China and manifests as simple fatty liver, non-alcoholic steatohepatitis, liver cirrhosis, and hepatocellular carcinoma. Studies have shown that intestinal flora can affect the development and progression of NAFLD via the "gut-liver axis" . Probiotics are active microorganisms with beneficial effects on the host, and more and more studies have found that probiotics play a positive role in improving NAFLD. They are cheaper, less harmful, and safer compared with antibiotics and surgery, and therefore, it may become a new method for the prevention and treatment of NAFLD. This article reviews the research advances in probiotics in the treatment of NAFLD, in order to provide a basis for the treatment of NAFLD using probiotics.

Diagnosis of pancreatic cancer based on biological information of saliva:an analysis of current status / 临床肝胆病杂志

Pancreatic cancer is one of common malignant tumors in the digestive system.There is still no effective means for the early diag-nosis of pancreatic cancer.As a mixture of oral gland secretion and oral mucosal transudate,saliva contains abundant biological information including microorganisms,proteins,and nucleic acids,which will change when the disease occurs.So saliva can be used for the early diag-nosis of pancreatic cancer.Through summarizing and analyzing the current studies and advantages of its application for early diagnosis,this article suggests that saliva bioinformatics holds promise for the application in the early diagnosis of pancreatic cancer.

Effects of gastric bypass versus medicine administration in obese patients with type 2 diabetes / 中华内分泌代谢杂志

Objective To assess the effects of gastric bypass versus medical therapy in patients with obesity and type 2 diabetes. Methods The Cochrane library, Embase, PubMed, Chinese biomedical literature database and Wanfang database up to April 2014 were searched. Randomized controlled trails(RCTs) of frequently-used bariatric surgery for obese patients with type 2 diabetes were included. Study selection, data extraction, quality assessment, and data analyses were performed according to the Cochrane standards. Results Four RCTs involving 157 patients in the gastric bypass groups and 152 patients in the medical therapy group were enrolled. Compared with medical therapy, gastric bypass for type 2 diabetes significantly decreased the levels of HbA1C(mean difference = -1. 85% , 95% CI -2. 15 ~ -1. 56, P< 0. 01), fasting blood glucose( standard mean difference = - 0. 90 mmol/ L, 95% CI-1. 24 ~ -0. 57, P<0. 01), body weight(mean difference=-23. 39 kg, 95% CI -29. 17 ~ -17. 61, P<0. 01), waist circumference(mean difference= -15. 36 cm, 95% CI -17. 51 ~ -13. 22, P<0. 01) and the dose of hypoglycemic medicine; while it increased the number of patients with HbA1C<6% (RR=5. 49, 95% CI 2. 22 ~ 13. 56, P<0. 01), the rate of adverse events(RR=1. 96, 95% CI 1. 42 ~ 2. 70, P<0. 01), and the level of high-density lipoprotein-cholesterol(mean difference=1. 24 mmol/ L, 95% CI 0. 64 ~ 1. 84, P<0. 01). Conclusions Gastric bypass surgery is more effective compared with medical therapy alone for obese patients with type 2 diabetes. Further intensive RCTs of high-quality in multiple centers with long-term follow-up should be carried out to provide more reliable evidences.

Meta-analysis of total thyroidectomy for multinodular goiter / 中南大学学报(医学版)

OBJECTIVE@#To systematically evaluate the efficiency and safety of total thyroidetomy (including near-total tyhroidectomy) versus subtotal thyroidectomy for multinodular goiter.@*METHODS@#The literatures were searched from Cochrane Library, PubMed, Embase, Chinese Biological Medical Datebase, Chinese National Knowledge Infrastructure, and Chinese Science and Technology Journal Full-text Database as of November 2013. We included all randomizad controlled trials on total (including near-total) versus subtotal thyroidectomy in the treatment of multinodular goiter. The collecting of data and quality assessment were respectively completed by 2 researchers. RevMan5.1 software was used for Meta-analysis.@*RESULTS@#We collected 7 literatures conforming to the standard, incuding 2 192 patients. The Metaanalysis outcomes showed that total thyroidectomy was associated with lower nodule recurrence rate (OR=0.13, 95% CI: 0.07-0.22, P<0.001) and higher in transient hypoparathyroidism rate (OR=2.33, 95% CI: 1.72-3.17, P<0.001). However, no statistical difference was seen comparing total and subtotal thyroidectomy in permanent recurrent laryngeal nerve paralysis rate (OR= 0.81, 95% CI: 0.24-2.74, P=0.74) and permanent hypoparathyroidism rate (OR=2.94, 95% CI: 0.48- 18.11, P=0.24).@*CONCLUSION@#Nodule recurrence rate of total thyroidectomy for multinodular goiter is lower than subtotal thyroidectomy and does not increase permanent complications.

Meta Analysis of Lentinan Injection plus Cisplatin in Treatment of Malignant Pleural Effusion / 中草药·英文版

Objective To evaluate the efficacy and safety of lentinan injection plus cisplatin (LIC) in the treatment of malignant pleural effusion (MPE).Methods We searched the database of Cochrane Library,PubMed,EMBASE,ISI Web of Knowledge,Chinese Biomedical Literature Database,Chinese Scientific Journals Full-text Database,Chinese Journal Full-text,and Google Scholar,etc.,up to February 28th,2011 to identify randomized controlled trials (RCTs) about lentinan injection (LI) for MPE,evaluate the quality of the included studies,and analyze the data by Cochrane Collaboration's RevMan5.0 software.Results Twenty-nine RCTs involving 1831 patients were included.Meta analysis results suggested that there were some differences when comparing LIC with control groups suffering from MPE,for LIC could improve the near-term curative effect and the quality of life to some extent.Besides,compared with chemotherapy alone,LI plus chemotherapy had an advantage in relieving adverse reactions,such as gastrointestinal reactions,myelosuppression,chest pain,and general malaise.Conclusion The current evidence indicates that LI may have adjuvant therapeutic effects for MPE.
