Mechanisms of eleutheroside for treatment of diabetes mellitus type 2 based on network pharmacology / 药学学报

Seven main components in eleutheroside were used as research objects, and the mechanism of action of total eleutheroside for treatment of diabetes mellitus type 2 was investigated by network pharmacology. The SwissTargetPrediction, GeneCard, and String platforms were used to predict the 35 potential targets of these 7 components that are related to diabetes mellitus type 2. Then we used cytoscape 3.6.1 to build a "component-target" network map and used the Networkanalyzer tool for topology analysis. Gene ontology (GO) enrichment analysis and KEGG pathway enrichment analysis were performed on the DAVID6.8 platform, and the "component-target-path" network map was constructed based on the enrichment results. Those components mainly used in diabetes mellitus type 2 were screened as core components, and the core components were docked with key disease target proteins to verify the potential mechanism of the total eleutheroside. After screening, 8 important pathways associated with diabetes mellitus type 2 were identified. This study showed that eleutheroside A, eleutheroside D, eleutheroside E and sesamin played key roles in insulin resistance, apoptosis and inflammation pathways. The total eleutheroside may ameliorate type 2 diabetes mainly through regulating signal transducer and activator of transcription factors (STATs), non-receptor protein tyrosine phosphatase (PTPN) 1, PTPN2, c-Jun N-terminal kinase (JNK), and p38 mitogen activate protein kinase. These components worked together through multiple signaling pathway. Based on our data, eleutheroside is proposed as a novel therapeutic strategy for treatment of type 2 diabetes.

Risk factors analysis of postsurgical gastroparesis syndrome and its impact on the survival of gastric cancer after subtotal gastrectomy / 中华胃肠外科杂志

<p><b>OBJECTIVE</b>To investigate the risk factors of postsurgical gastroparesis syndrome (PGS) after subtotal gastrectomy in gastric cancer and the impact of PGS on prognosis.</p><p><b>METHODS</b>Clinical data of 422 patients who underwent subtotal gastrectomy for gastric cancer in the Central Hospital of Huzhou Sity from January 2004 to May 2010 were analyzed retrospectively. Risk factors of PGS were indentified and the recurrence-free survival was compared between the patients with and without PGS.</p><p><b>RESULTS</b>PGS occurred in 42 patients (9.5%). Univariate analysis showed that: age over 65, combination of anxiety disorder, low-albuminemia in perioperative period, pyloric obstruction in preoperative period, high serume glucose level (≥ 11.2 mmol/L) in postoperative period, Billroth II (gastroenterostomy, operation time over 4 hours, using patient-controlled analgesia, or intravenous fluid over 3500 ml/d (all P<0.05) were prone to develop PGS. These might be potential clinical risk factors associated to PGS. Correlation analysis showed the number of clinical risk factors was positively correlated with the incidence of PGS (r=0.967, P<0.05). A total of 215 cases (50.9%) were followed up for 3-60 months. The mean recurrence-free survival time of patients with PGS was 26.1 months, which was shorter than that of those without PGS (33.4 months, P=0.029).</p><p><b>CONCLUSIONS</b>Gastric cancer patients with the clinical risk factors mentioned above are prone to develop PGS after subtotal gastrectomy. PGS is associated with poor prognosis.</p>

Efficacy of postoperative antiviral combined transcatheter arterial chemoembolization therapy in prevention of hepatitis B-related hepatocellular carcinoma recurrence / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>Recurrence of hepatitis B-related hepatocellular carcinoma (HCC) after curative resection is the leading factor influencing the prognosis of the disease. Therefore, further improvement of long-term survival may depend on the prevention and treatment of the recurrent tumor. The aim of this research was to investigate the role of antiviral therapy and postoperative transcatheter arterial chemoembolization (TACE) in the prevention and treatment of hepatitis B-related HCC recurrence.</p><p><b>METHODS</b>One hundred and twenty patients who underwent curative resection of hepatitis B-related HCC between January 2005 and June 2008 at our hospital were enrolled. Patients were divided into four groups according to the post-operative adjuvant therapy they received, i.e., control, antiviral therapy group, TACE group, and combined group. The disease-free survival (DFS) and the 12-, 24-, 36-month cumulative recurrence rates were studied.</p><p><b>RESULTS</b>There was no significant difference between isolated postoperative antiviral therapy group and control in terms of disease-free survival (P = 0.283), while it was significantly higher in the TACE group compared to control (P = 0.019). In all patients, however, viral prophylactic therapy combined with/without TACE brought a favorable result compared to those only with/without TACE (P < 0.001). Similarly, no matter combined with or without antiviral treatment, postoperative TACE prolonged DFS (P = 0.015). Naturally, a combination of viral prophylactic therapy on the baseline TACE significantly benefited patients' postoperative DFS (P = 0.047) and vice verse (P = 0.002). The 24-month cumulative recurrence rates of combined group were significantly lower than that of isolated control group and antiviral therapy (P < 0.001 and P = 0.011 respectively). However, 36-month recurrence rate was significantly different in the control group compared to the TACE group and combined group (P = 0.040 and 0.002 respectively); same as the antiviral group compared to the combined group (P = 0.034).</p><p><b>CONCLUSIONS</b>Post-operative TACE prevents early recurrence while antiviral therapy prevents late recurrence of HCC. Combination of antiviral therapy and TACE are suggested for prevention in HCC patients with high risk of recurrence.</p>

Evaluation of lymph node dissection in the central neck area in managing thyroid microcarcinoma / 中华肿瘤杂志

<p><b>OBJECTIVE</b>To evaluate lymph node dissection in the central neck area to treat micro-sized thyroid carcinoma.</p><p><b>METHODS</b>The clinical data of 65 surgically treated thyroid microcarcinoma patients in our hospital were retrospectively reviewed.</p><p><b>RESULTS</b>In this series, the positive metastasis rate of cervical lymph node was 40%. A total of 62 patients had been followed up until the data were reviewed. None was found to be dead nor having distant metastasis. Five patients were re-operated due to countralateral lobe meatstasis 3 years after initial operation, 2 of them had developed para-tracheal lymph node metastasis; another 2 cases underwent functional neck lymph node dissection due to lymph node metastasis on the operated side 2 years later.</p><p><b>CONCLUSION</b>Thyroidectomy with lymph node dissection of the central neck area is more effective than the thyroidectomy alone for managing thyroid microcarcinoma. It can improve the quality of life and survival through reducing cervical lymph node metastasis.</p>
