Objective To review the advance in the experimental studies of microRNA(miRNA) and the relationship between miRNA and stem cells. Methods The related literature was reviewed, and the research findings of miRNA and stem cell were summarized. Results miRNA was noncoding small RNA (20-25 nt) involved in posttranscriptional change, that have been shown to regulate gene expressions. Ithas been reported that some kinds of miRNAs were likely important regulators forstem cells maintaining their state of selfrenewal，and play key roles in theirdifferentiation. Conclusion miRNA as regulation of gene expressions, can be served as a new way for stem cells research.
ObjectiveTo systematically review the effects of Liujunzi decoction on improving the quality of life (QOL) of patients with advanced primary liver cancer.
MethodsDatabases including MEDLINE, EMbase, SCI, The Cochrane Library (Issue 2, 2014), CBM, CNKI, VIP and WanFang Data were searched electronically from inception to July 2014 to collect randomized controlled trials (RCTs) about Liujunzi Decoction for advanced primary liver cancer. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Then, meta-analysis was performed by using RevMan 5.3 software.
ResultsA total of 7 RCTs involving 458 patients were included. The results of meta-analysis showed that the Liujunzi decoction group had significantly higher stability of QOL (RR=0.76, 95%CI 0.64 to 0.91, P=0.002), Karnofsky Performance Score (KPS) (MD=4.47, 95%CI 2.74 to 6.21, P<0.00001) and effective rate of TCM syndrome (RR=0.73, 95%CI 0.62 to 0.86, P=0.0001) than those of the control group.
ConclusionCurrent evidence shows that Liujunzi decoction could improve the QOL and KPS, and relieve TCM syndromes of patients with advanced primary liver cancer, especially for those with spleen deficiency-syndrome. Due to the limited quantity and quality of the included studies, the above conclusion still needs to be verified by carrying out more high-quality RCTs.
ObjectiveTo investigate the predictive value of thyroid transcription factor-1 (TTF-1) in the treatment of advanced lung adenocarcinoma with different chemotherapy regimens.MethodsA total of 126 patients with advanced lung cancer were divided into three groups according to the chemotherapy regimen, namely a pemetrexed+nedaplatin group (PEM+NDP group), a pemetrexed+cisplatin/carboplatin group (PEM+DDP/CBP group) and a third-generation (3G) chemotherapy+cisplatin/carboplatin group (3G agent+DDP/CBP group). The predictive value of TTF-1 in the above three treatment regimens was analyzed. The patients were followed up by telephone or outpatient visit until April 2017.ResultsThere were no significant differences in disease control rate or objective response rate between the three different chemotherapy regimens (all P>0.05). The survival rate of PEM+NDP group was significantly higher than that of PEM+DDP/CBP group and 3G agent+DDP/CBP group (9.68%vs. 5.56% and 6.80%, both P<0.05). ECOG score and brain metastasis were independent risk factors for the prognosis of chemotherapy regimens. TTF-1 was an independent risk factor for PEM+NDP therapy.ConclusionTTF-1 is an independent risk factor for PEM+NDP chemotherapy, but not for 3G agent + DDP/CBP or PEM+DDP/CBP regimens.
Objective To investigate the use of oral anti-diabetic drugs and sugar blood control situation in advanced aged patient with diabetic mellitus in a community health centre in order to provide references for rational drug use. Methods A cross-sectional survey about oral anti-diabetic drugs was carried out in senile diabetic patients who visited the community health centre and established complete health documents voluntarily from February 2012 to February 2013. Results There were 176 cases of advanced aged patients with type 2 diabetic mellitus, of which, 107 cases were female and 69 cases were male, whose age ranged from 80 to 94. Among 176 cases, there were 107 (60.80%) patients with type 2 diabetic mellitus combined with hypertension, chronic heart diseases, and stoke; 155 had oral anti-diabetic drugs (88.06%). 67.19% of patients who took one oral anti-diabetic drug chose α-glycosidase inhibitors, followed by sulfonylurea. 53.73% of patients who received combination therapy chose glycosidase inhibitors and sulfonylurea. For the treatment of anti-diabetic drugs, 73.68% of patients met the criteria (fasting blood sugar: no more than 8.0 mmol/L), with control rates of 73.56% for α-glycosidase inhibitors and 72.58% for sulfonylurea. More than half of the patients could not be evaluated for their glycosylated hemoglobin levels were not tested. Conclusion Doctors working in community health centres should choose oral anti-diabetic drugs according to patients’ own conditions when treating advanced aged patients with diabetic mellitus in order to avoid adverse reaction such as hypoglycemia. Glycosidase inhibitors are the mostly used drug in the community health centre because it is safe with less adverse reaction when used in senile people and it could ideally control their blood sugara.
ObjectiveTo summarized the clinical experience on laparoscopic radical surgery in patients with advanced distal gastric cancer. MethodsThe clinical data of 26 patients with advanced distant gastric cancer undergoing laparoscopic gastrectomy were retrospectively analyzed. ResultsLaparoscopic distal gastrectomy was performed successfully in all patients. The operation time was (283.2±27.6) min (270-450 min) and the blood loss was (178.4±67.4) ml (80-350 ml). The time of gastrointestinal function recovery was (2.8±1.2) d (2-4 d), out of bed activity time was (1.5±0.4) d (1-3 d) and liquid diet feeding was (3.5±1.4) d (3-4 d). The hospital stay was (10.0±2.6) d (7-13 d). The number of harvested lymph nodes was 11 to 34 (17.8±7.3). The distance from proximal surgical margin to tumor was (7.0±2.1) cm (5-12 cm) and the distance from distal surgical margin to tumor was (5.5±1.8) cm (4-8 cm), thus surgical margins were negative in all samples. All patients were followed up for 3-48 months (mean 18.5 months), two patients with poorly differentiated adenocarcinoma died of extensive metastasis in 13 and 18 months, respectively, and other patients survived well. ConclusionsLaparoscopic radical gastrectomy with D2 lymphadenectomy for advanced gastric cancer is safe and feasible. However, the advantage of laparoscopic technique over the conventional open surgery requires further study.
Objective To explore the feasibility, safety, efficacy and mechanism of intraoperative regional chemotherapy of advanced gastric cancer.Methods The related literatures were reviewed and analyzed. Results Compared with systemic chemotherapy, intraoperative regional chemotherapy of advanced gastric cancer could increase blood drug concentration of cancerous tissue, reduce the systemic toxic side effects, increase survival rate and improve the quality of life. Conclusion Intraoperative regional chemotherapy, as an adjuvant treatment of advanced gastric cancer, has been gradually applied to clinic because of the definite curative effect, which is worth popularizing. However, it needs systemic researches and accumulation of cases.
ObjectiveTo investigate the risk factors of hepatoduodenal lymph node (HDLN) metastasis in patients with advanced gastric cancer and its effect on prognosis.
MethodsClinical datas of patients with advanced gastric cancer who underwent D2 radical gastrectomy for gastric cancer and HDLN dissection between Jan 2011 and Nov 2013 in department of general surgery of Ankang Central Hospital were retrospectively reviewed. Multivariate logistic regression analysis was performed to identify the independent risk factors associated with HDLN metastasis. Survival curves were performed to compare the survival rate of patients with or without HDLN metastasis and of patients with HDLN metastasis or with other lymph node metastasis. A Cox proportional hazards model was used for the multivariate analysis of risk factors for death in advanced gastric cancer.
ResultsThe incidence of HDLN metastasis was 10.7% in patients with advanced gastric cancer. Multivariate logistic regression analyses revealed that the middle or lower stomach cancer (OR=6.014, P=0.002) and stage T3 or T4 (OR=5.133, P=0.021) were independent risk factors for HDLN metastasis. The 2-year overall survival (OS) rate was 36.7% in patients with HDLN metastasis. It was lower in patients with HDLN metastasis compared with those without (P=0.002). Limited to node-positive patients, patients with HDLN metastasis demonstrated decreased 2-year OS rate compared with node-positive patients without HDLN metastasis (P=0.027). Cox proportional hazard analysis identified poorly differentiated or undifferentiated cancer, stage of T3 or T4, and HDLN metastasis were independent poor prognostic factors in the patients with advanced gastric cancer (P < 0.05).
ConclusionsCancer located in the middle or lower stomach, and stage T3 or T4 were independent risk factors for HDLN metastasis in patients with advanced gastric cancer. HDLN metastasis demonstrated a poor prognosis.
Objective To investigate the feasibility and safety of laparoscopic-assisted gastrectomy for distant gastric cancer. Methods All 18 patients with distant gastric cancer receiving laparoscopic-assisted gastrectomy were analyzed. Results Laparoscopic-assisted distal gastrectomy was performed successfully in all patients. The mean operation time was (291.33±19.61) min. The mean blood loss was (151.32±71.78) ml. The mean numbers of harvested lymph node were 14.57±3.11. The mean time of gastrointestinal function recovery was (3.46±0.93) d, the mean out of bed activity time was (1.75±0.45) d. All patients were followed up for 1-24 months, mean 11 months. No local recurrence, trocar implant or distant metastasis happened. Conclusion Laparoscopic-assisted gastrectomy is a feasible and safe surgical procedure combined with minimal trauma and fast recovery.
Objective To evaluate the effectiveness and safety of lentinan on immune function in patients with advanced gastric cancer. Methods We searched MEDLINE (1969-2006), EMBASE (1984-2006), OVID (1969-2006), CENTRAL (Cochrane Central Register of Controlled Trials in The Cochrane Library) (Issue 4, 2006), the Chinese Biomedicine Database (1978-2006) and CNKI (1978-2006). We also handsearched relevant journals. Pharmaceutical companies were contacted to identify additional randomized controlled trials. We assessed the identified studies in order to include high quality studies. Results Ten studies (containing 786 patients) met the inclusion criteria. Six trials shown that lentinan+FAM had significant efficacy upon patients with advanced gastric cancer compared with FAM in overall response [Plt;0.01, RR1.70, 95%CI (1.39,2.09)]. In three trials, a significant effect of lentinan+FAM group compared with FAM group in quantity of CD3+ T, T4/T8, NK was found, but lower than FAM group in side- effect of digestive system [RR0.71, 95%CI (0.55,0.91)]. The other trail identified there were fewer side effects in lentinan+FAM group compared with FAM group, though did not discribe the overall response. In case the significant heterogeneity, meta-analysis could not be used for the other three trails included, since the components of chemotherapeutic agents (ATP+Co-A+Vc; DDP+ Epirubicin+5FU; 5FU+CF+VP16) were not the same. In the three trials, overall response was statistically significant better in the lentinan group than in the control group, and lentinan group could significantly increase the quantity of CD3+ T, T4/T8, NK compared with control group. Conclusions The present meta-analysis suggested that addition of lentinan to standard chemotherapy provided a significant advantage over chemotherapy alone in terms of efficacy for patients with advanced gastric cancer. However, most of trials included in the review were of low quality, therefore, it is of necessity to conduct multi-center randomized-controlled trials of high quality.
ObjectiveTo introduce the current study of the metastatic mode and operation methods in advanced gallbladder carcinoma. MethodsThe literatures about metastatic mode and operation methods of advanced gallbladder carcinoma in recent 5 years were reviewed.ResultsLymph node and hepatic invasion were the main mode of advanced gallbladder carcinoma. The Japanese Society of Biliary Surgery （JSBS） classification to gallbladder carcinoma was more reasonable than the UICC classification. The survival rate after radical resection was higher than that after cholecytectomy in patients with T2n1-2M0. In the patients that tumor extended adjacent organs but the lymph node metastatic localized within n2, extended radical resection provided a survival advantage. If the patients’ tumor was not resectable or who had lymph node metastasis beyond n3, the benefit of extended radical resection seemed limited.ConclusionIn the carefully selected patients, extended radical resection will improve the prognosis of advanced gallbladder carcinoma.
