AIMTo evaluate the impact of enhanced recovery after surgery (ERAS) programs on postoperative complications of pancreatic surgery.METHODSComputer searches were performed in databases (including PubMed, Cochrane Library and Embase) for randomized controlled trials or case-control studies describing ERAS programs in patients undergoing pancreatic surgery published between January 1995 and August 2017. Two researchers independently evaluated the quality of the studies’ extracted data that met the inclusion criteria and performed a meta-analysis using RevMan5.3.5 software. Forest plots, demonstrating the outcomes of the ERAS group vs the control group after pancreatic surgery, and funnel plots were used to evaluate potential publication bias.RESULTSTwenty case-control studies including 3694 patients, published between January 1995 and August 2017, were selected for the meta-analysis. This study included the ERAS group (n = 1886) and the control group (n = 1808), which adopted the traditional perioperative management. Compared to the control group, the ERAS group had lower delayed gastric emptying rates [odds ratio (OR) = 0.58, 95% confidence interval (CI): 0.48-0.72, P < 0.00001], lower postoperative complication rates (OR = 0.57, 95%CI: 0.45-0.72, P < 0.00001), particularly for the mild postoperative complications (Clavien-Dindo I-II) (OR = 0.71, 95%CI: 0.58-0.88, P = 0.002), lower abdominal infection rates (OR = 0.70, 95%CI: 0.54-0.90, P = 0.006), and shorter postoperative length of hospital stay (PLOS) (WMD = -4.45, 95%CI: -5.99 to -2.91, P < 0.00001). However, there were no significant differences in complications, such as, postoperative pancreatic fistulas, moderate to severe complications (Clavien-Dindo III- V), mortality, readmission and unintended reoperation, in both groups.CONCLUSIONThe perioperative implementation of ERAS programs in pancreatic surgery is safe and effective, can decrease postoperative complication rates, and can promote recovery for patients.
The rapid development of chiral inorganic nanostructures has greatly expanded from intrinsically chiral nanoparticles to more sophisticated assemblies made by organics, metals, semiconductors, and their hybrids. Among them, lots of studies concerning on hybrid complex of chiral molecules with achiral nanoparticles (NPs) and superstructures with chiral configurations were accordingly conducted due to the great advances such as highly enhanced biocompatibility with low cytotoxicity and enhanced penetration and retention capability, programmable surface functionality with engineerable building blocks, and more importantly tunable chirality in a controlled manner, leading to revolutionary designs of new biomaterials for synergistic cancer therapy, control of enantiomeric enzymatic reactions, integration of metabolism and pathology via bio-to nano or structural chirality. Herein, in this review our objective is to emphasize current research state and clinical applications of chiral nanomaterials in biological systems with special attentions to chiral metal- or semiconductor-based nanostructures in terms of the basic synthesis, related circular dichroism effects at optical frequencies, mechanisms of induced optical chirality and their performances in biomedical applications such as phototherapy, bio-imaging, neurodegenerative diseases, gene editing, cellular activity and sensing of biomarkers so as to provide insights into this fascinating field for peer researchers.
ObjectiveThe aim of the study was to evaluate the effectiveness, safety, and cost associated with Wenxin keli in the treatment of cardiovascular diseases based on meta-analysis.MethodsThe terms “Wenxin keli” and “Wenxin” were used as the search terms in the PubMed, ProQuest, Springer, the Cochrane Library, CNKI (China National Knowledge Infrastructure), VIP (Chinese Scientific Journals Database), and Wan fang electronic databases (from January 2000 to October 2015). Relevant print journals and conference papers were also searched. Studies on randomized controlled trials (RCTs) of Wenxin keli used in the treatment of cardiovascular diseases were screened, and its indications were classified. Meta-analysis of these studies was conducted using the RevMan 5.2 software.ResultsA total of 49 RCTs (n=4,610) were included, 29 of which focused on arrhythmia, seven on angina, seven on heart failure, two on viral myocarditis, and four on menopausal syndrome. Analysis of the therapeutic indications of Wenxin keli showed that it was comparatively more curative and effective than other available treatments for cardiovascular diseases.ConclusionWenxin keli showed better clinical efficacy in the treatment of arrhythmia, angina, and heart failure; however, more high-quality evidence is needed to support its use in the clinical setting.
Background & Aims: Current studies have indicated that long non-coding RNAs (lncRNAs) could act as tumor biomarkers for disease diagnosis and prognosis prediction. In this study, we mainly focused on determining the expression of circulating lncRNAs in patients suffering for hilar cholangiocarcinoma (HC), aiming to reveal the potential lncRNA as a fingerprint. Methods: A total 12 lncRNAs were previously proven to be aberrantly expressed in HC tumor tissues. All of the 12 lncRNAs were selected as candidate targets for subsequent circulating lncRNA assay. The candidate lncRNAs were validated by qRT-PCR arranged in training and validation sets. The risk score analysis was employed. Data was presented with receiver operating characteristic curve (ROC). Results: Circulating PCAT1, MALAT1, and CPS1-IT1 were significantly increased in plasma samples of HC patients in both the training set and validation set. Through ROC analysis, we found that the three plasmatic lncRNAs presented the area under ROC curve value (AUC) as 0.784, 0.860, and 0.677. Further combination with the three factors indicated a higher power (AUC, 0.893; sensitivity, 85.5%; specificity, 93.2%). Conclusion: This was the first time to reveal the potential circulating fingerprints for predicting HC. PCAT1, MALAT1, and CPS1-IT1 may act as novel early diagnosis biomarkers for predicting HC.
Purpose: It has been reported that miRNA-124 inhibits hepatocellular carcinoma (HCC) progression, while lncRNA-UCA1 promotes HCC. The aim of this study is to find whether miRNA-124, as a tumor suppressor in HCC can inhibit lncRNA-UCA1 in HCC cell. Methods: Tumor tissues and adjacent healthy tissues were obtained from 66 patients diagnosed with HCC in Binzhou Medical University Hospital from January 2011 to January 2013. Cell proliferation assay, in vitro cell migration and invasion assay were applied for the research. Results: In the present study we found that miRNA-124 was downregulated, while lncRNA-UCA1 was upregulated in tumor tissues comparing to adjacent healthy tissues of HCC patients. Expression of miRNA-124 and lncRNA-UCA1 in tumor tissues were not affected by HBV or HCV infection. Analysis of followed-up data revealed that low miRNA-124 level and high lncRNA-UCA1 level were closely correlated with poor survival. Overexpression of miRNA-124 led to inhibited lncRNA-UCA1 expression in cells of HCC cell lines, while overexpression of lncRNA-UCA1 failed to significantly affect miRNA-124 expression. Expression levels of miRNA-124 and lncRNA-UCA1 were inversely and significantly correlated in tumor tissues but not in adjacent healthy tissues. Overexpression of miRNA-124 led to inhibited, while overexpression of lncRNA-UCA1 led to increased proliferation, migration and invasion rates of HCC cell lines. In addition, lncRNA-UCA1 overexpression attenuated the inhibitory effects of miRNA-124 overexpression on cancer cell proliferation, migration and invasion. Conclusion: Therefore, miRNA-124 may inhibit the proliferation, migration and invasion of cancer cell in hepatocellular carcinoma by downregulating lncRNA-UCA1.
Rationale:Mesenteric fibromatosis (MF) is a rare tumor whose biological behavior is intermediate between benign fibrous neoplasms and fibrosarcomas, and the characteristic of these tumors are local aggressive lesions which is prone to local recurrence but non-metastasizing. The common symptom is abdominal distention or painless mass. We report a case of giant MF in abdominal cavity with abdominal distention as the main symptom.Patient concerns:A 26-year-old male presented with 2-month history of abdominal distention, lack of appetite, and symptoms grew progressively more debilitating with time.Diagnoses:This patient underwent a contrast-enhanced computed tomography scan which showed a giant (37 × 25 × 13 cm), inhomogeneous enhancing, well-defined, and soft tissue density mass in abdominal cavity, possibly arising in mesocolon, which suggested a high possibility of MF. The postoperative pathology showed that the tumor cells to be positive for β-catenin, vimentin, negative for CD34, CD117, DOG-1, S-100, Desmin, which confirmed the diagnosis of MF.Interventions:Exploratory laparotomy was performed, which revealed a large mass involving the transverse colon wall, the root of mesocolon, and encasing the middle colic vessels and the 1st branch of jejunal arteries. The complete surgical resection was performed and the mass weighted 10 kilograms (kg).Outcomes:The patient recovered uneventfully and was discharged 9 days after surgery. Three-month, 6-month, 12-month and 18-month on follow-up after surgery, showed no evidence of recurrence.Lessons:The MF is a very rare tumor, especially a giant tumor (10 kg) involving the muscular layer of colon wall. In addition, treatment of giant MF still remains a challenge. We consider that surgical resection with negative margins is the goal but not at the expense of damaging the function of vital organs. Specific measures should be considered based on the individual patient in order to relieve symptoms and improve quality of life.
Background. Intraoperative fluid (IOF) administration plays an important role during major abdominal surgery although increased fluid intake can adversely influence postoperative outcomes. However, the effect of the IOF rate on the outcomes of pancreatoduodenectomy (PD) is unclear. Methods. 151 patients, who underwent PD at Binzhou Medical University Hospital between January 2010 and May 2017, were categorized into three groups according to IOF rates (ml/kg/hr): restricted (<10, n=47), standard (10–15, n=76), and liberal (>15, n=28). Results. The overall postoperative morbidity was 56.95%. The incidence of postoperative pancreatic fistula (POPF) was 11.26%. The in-hospital mortality rate was 7.28% with the most common cause being grade C POPF and secondary intra-abdominal infections. The patients in the liberal group had significantly higher incidences of POPF (25%) and respiratory complications (21.43%). The other outcome parameters such as recovery of bowel function, hospital stay, and postoperative daily drainage were similar among the groups. Multivariable analysis confirmed the IOF rate to be most strongly associated with POPF (odds ratio: 5.195, confidence interval: 1.142–23.823, P=0.023) and respiratory complications (odds ratio: 7.302, confidence interval: 0.676–58.231, P=0.025). Conclusions. The IOF rate significantly affects the incidence of POPF and respiratory complications after PD. Careful patient-oriented fluid therapy may help to prevent these complications.
