Background: Millions of patients undergo cardiac surgery each year. The red blood cell distribution width (RDW) could help predict the prognosis of patients who undergo percutaneous coronary intervention or coronary artery bypass surgery. We investigated whether the RDW has robust predictive value for the 30-day mortality among patients in an intensive care unit (ICU) after undergoing cardiac surgery. Methods: Using the Medical Information Mart for Intensive Care-IV Database, we retrieved data for 11,634 patients who underwent cardiac surgery in an ICU. We performed multivariate Cox regression analysis to model the association between the RDW and 30-day mortality and plotted Kaplan–Meier curves. Subgroup analyses were stratified using relevant covariates. Receiver operating characteristic (ROC) curves were used to determine the predictive value of the RDWs. Results: The total 30-day mortality rate was 4.2% (485/11,502). The elevated-RDW group had a higher 30-day mortality rate than the normal-RDW group (P < 0.001). The robustness of our data analysis was confirmed by performing subgroup analyses. Each unit increase in the RDW was associated with a 17% increase in 30-day mortality when the RDW was used as a continuous variable (adjusted hazard ratio = 1.17, 95% confidence interval, 1.10–1.25). Our ROC results showed the predictive value of the RDW. Conclusions An elevated RDW was associated with a higher 30-day mortality in patients after undergoing cardiac surgery in an ICU setting. The RDW can serve as an efficient and accessible method for predicting the mortality of patients in ICUs following cardiac surgery.

Metabolic associated fatty liver disease (MAFLD) is a hotspot in the field of fatty liver disease at present and it has become the most common chronic liver disease around the world. It is predicted that the incidence rates of MAFLD and related liver cirrhosis will continue to grow in the next 20 years and that they will become new global health issues. Acute-on-chronic liver failure (ACLF) is defined as a clinical syndrome of acute or subacute liver function decompensation within a short period of time in the presence of existing chronic liver diseases, with the main clinical manifestations of ascites, jaundice, coagulation disorder, and hepatic encephalopathy. Based on the existing data, this article discusses the epidemiology, pathogenesis, treatment and management strategies, and future prospects of MAFLD-ACLF.

Nowadays, PDCA circle is a widely used theory of quality management system. Through the PDCA approach, the management reform was conducted in 17 anesthesia teachers of the Anesthesiology department. After 18 months of training and promotion, the problems such as lack of enthusiasm for teaching, uneven level of teachers, and boring single teaching method were basically solved, which improved their teaching skills. Certain effectiveness has been achieved in teacher training management including continuity of quality management, timely feedback and emphatically improvement, student-center teaching philosophy, and mutual promotion of teaching and learning.

OBJECTIVE: To investigate the safety of the controllable ileostomy with pipe in view of histology. METHODS: Twenty-eight Beagle dogs undergoing controllable ileostomy with pipe were studied. The special fistula tube with balloon was placed into the hole locating at the cecal root opposing the mesenteric side, and fixed by double knot compression method. RESULTS: The fistula tube was removed 14 days after surgery, then the safety of the procedure was preliminarily evaluated by gastrointestinal radiography and anatomical observation. The small intestine tissue at the compression suture was used as the experimental segment, and the small intestine tissue at the proximal non-compression suture was used as the control segment. The histological staining and the immunohistochemical staining of S-100 protein, c-kit protein and α-smooth muscle actin(α-SMA) protein between two segment were compared, while quantitative comparison of myenteric plexus, intestinal Cajal cell(ICC) and smooth muscle cells in intestinal wall was carried out. After removal of fistula tube at 14 days postoperative, the dogs were normal in feeding and defecation. The digestive tract radiography showed that the intestine was patent without obvious stenosis and obstruction. The dogs were dissected 21 days after operation. The abdominal sinus ostium was well healed and the internal sinus was well formed. Under gross inspection, blood supply, morphology and motor function of experimental intestine segment were similar from the proximal and distal segments of control intestine. S-100 immunohistochemical staining showed that the morphology and distribution of S-100 protein positive cells and "blank area" cells in the experimental and control segments were consistent. Myenteric plexus counting showed that the experimental segment was 3.62±1.82/field and the control segment was 3.27±1.62/field, whose difference was not statistically significant(t=1.30, P=0.20). Immunohistochemical staining of c-kit showed that the distribution of c-kit positive cells in both segments was consistent. Counting of the number of ICCs in myenteric plexus revealed that experimental segment was 2.96±2.57/plexus, and control segment was 2.49±1.80/plexus without significant difference(t=1.81, P=0.07). Immunohistochemical staining of α-SMA showed that the morphology and distribution of smooth muscle cells in whole intestinal wall(muscle layer, longitudinal muscle, ring muscle) in experimental and control segments were consistent. The average absorbance(A) value of α-SMA staining in ring muscle layer was detected and quantified. The experimental segment was 0.15±0.03 and control segment was 0.14±0.04 without significant difference(t=1.16, P=0.25). CONCLUSION The technique of controllable ileostomy with pipe is safe in view of histology, which may replace the traditional protective ileostomy.

OBJECTIVETo investigate the expression of transcriptional coactivator with PDZ-binding motif(TAZ) in colon cancer tissues and its association with clinicopathological parameters and prognosis of patients.

METHODSThe expression of TAZ protein was detected in 56 resected colon cancer tissues and matched tumor-adjacent tissues using immunohistochemistry. The positive expression rate of TAZ was compared between patients with different clinicopathological features. The association between TAZ expression and prognosis was analyzed.

RESULTSExpression of TAZ protein located in the nucleolus. The positive expression rate of TAZ in colon cancer tissues was significantly higher than that in matched tumor-adjacent tissues(73.2% vs. 12.5%, P=0.000). Clinicopathological evaluation suggested that the expression of TAZ protein was associated with tumor size(P=0.009), depth of infiltration(P=0.026), lymph node metastasis (P=0.007) and TNM staging(P=0.004). Colon cancer patients with negative expression of TAZ showed a better 5-year survival as compared with those with positive expression of TAZ (66.7% vs. 22.9%, P=0.0017). Multivariate Cox regression analysis revealed that positive TAZ expression was an independent factor for predicting poor prognosis in colon cancer (HR:3.532, 95% CI: 1.3-9.9, P=0.016).

CONCLUSIONThe expression of TAZ protein is up-regulated in colon cancer tissues and its high expression is associated with poor prognosis of colon cancer patients.

OBJECTIVETo investigate miR-146a expression in colonic cancer and its clinical implications.

METHODSQuantitative real-time PCR was employed to detect the levels of miR-146a expression in colonic cancer tissues, pair-matched adjacent normal tissues and different colonic cancer cell lines. MTT essay was used to evaluate the proliferation of colonic cancer SW260 cells transfected with miR-146a mimics, and the cell cycle and apoptosis of the cells were analyzed with flow cytometry.

RESULTSCompared with the normal tissues, 38 of the 43 colonic cancer samples showed down-regulated miR-146a expression, which was associated with poor tumor differentiation. The expression of miR-146a in the tumor tissues was significantly correlated with tumor size and clinical stages. The patients with high miR-146a expression levels had significantly longer total survival time than those with low expression of miR-146a. In SW260 cell cultures, transfection with miR-146a mimics significantly inhibited cell growth (P<0.05) and increased the cell apoptosis rate (11.9% vs 5.9%) but produced no obvious effect on cell cycle.

CONCLUSIONSmiR-146a may serve as a potential therapeutic target for colonic cancer for its role in inhibiting colonic cancer cell proliferation.
