ABSTRACT
Quality management and control of single disease is a means to continuously improve medical quality and safety by building a set of quality control indicators and evaluation systems based on the whole process of disease diagnosis and treatment. In the actual single disease management process, the reporting of each disease involved data from various systems such as electronic medical records, and the data integration was difficult. While the traditional manual reporting method took a lot of time and the data accuracy could not be guaranteed. In the development process of hospital informatization, a hospital has designed a set of intelligent full-closed loop single disease management platform based on the hospital information system, by integrating the existing human and information data resources of the hospital. This platform integrated functions of single disease intranet reporting, in-depth capture of reporting elements, single-disease quality index management, and single-disease real-time intelligent control, in order to promote more refined and intelligent disease management and thus steadily improve medical quality and safety.
ABSTRACT
ObjectiveAt present, there are few studies on prognostic indicators for patients with severe traumatic brain injury (STBI). This paper aims to explore its significance by analyzing the demographic characteristics of patients with STBI, as well as parameters such as clinical laboratory test indicators.MethodsA retrospective analysis was performed on 139 STBI patients admitted to the Department of Emergency Medicine, General Hospital of Eastern Theater Command from January 2017 to December 2018. According to the 28-day death event, the participants were divided into the survival group (n=108) and the death group (n=31). Indicators such as Glasgow Coma Score (GCS), red blood cell distribution width (RDW), platelet distribution width (PDW) and clot-related indicators were collected. Univariate and multivariate logistic regression were used to analyze the risk factors related to death, and receiver operating characteristic (ROC) curve was adopted to determine their prognostic values.ResultsThere were significant differences in GCS, RDW and PDW between the two groups. RDW (OR=4.577, 95% CI: 1.704-12.291), PDW (OR=1.346, 95% CI: 1.093-1.657) and GCS (OR=0.469, 95% CI: 0.301-0.730) were risk factors for death of STBI patients. The area under the curve (AUC) of RDW, PDW and GCS scores were 0.735 (0.640-0.840), 0.675 (0.553-0.796) and 0.737 (0.638-0.837), respectively, and the AUC of the combination of the three was 0.840 (0.748-0.932), which was significantly better than that of single diagnosis.ConclusionRDW, PDW combined with GCS can effectively evaluate the prognosis of patients with STBI, which has important guiding value for clinicians′ diagnosis and treatment.
ABSTRACT
Purpose@#Triple-negative breast cancer (TNBC) is highly malignant and has poor prognosis and a high mortality rate. The lack of effective therapy has spurred our investigation of new targets for treating this malignant cancer. Here, we identified RON (macrophage-stimulating 1 receptor) and MET (MET proto-oncogene, receptor tyrosine kinase) as a prognostic biomarker and therapeutic targets for potential TNBC treatment. @*Materials and Methods@#We analyzed RON and MET expression in 187 primary TNBC clinical samples with immunohistochemistry. We validated the targeted therapeutic effects of RON and MET in TNBC using three tyrosine kinase inhibitors (TKIs): BMS-777607, INCB28060, and tivantinib. The preclinical therapeutic efficacy of the TKIs was mainly estimated using a TNBC xenograft model. @*Results@#Patients with TNBC had widespread, abnormal expression of RON and MET. There was RON overexpression, MET overexpression, and RON and MET co-overexpression in 63 (33.7%), 63 (33.7%), and 43 cases (23.0%), respectively, which had poor prognosis and short survival. In vivo, the TKI targeting RON ant MET inhibited the activation of the downstream signaling molecules, inhibited TNBC cell migration and proliferation, and increased TNBC cell apoptosis; in the xenograft model, they significantly inhibited tumor growth and shrank tumor volumes. The TKI targeting RON and Met, such as BMS-777607 and tivantinib, yielded stronger anti-tumor effects than INCB28060. @*Conclusion@#RON and MET co-overexpression can be significant pathological characteristics in TNBC for poor prognosis. TKIs targeting RON and MET have stronger drug development potential for treating TNBC.

ABSTRACT
Identifying a target molecule that is crucially involved in pancreatic tumor growth and metastasis is necessary in developing an effective treatment. The study aimed to investigate the role of the eukaryotic translation initiation factor 3a (eIF3a) in the cell proliferation and motility in pancreatic cancer. Our data showed that the expression of eIF3a was upregulated in pancreatic ductal adenocarcinoma as compared with its expression in normal pancreatic tissues. Knockdown of eIF3a by a specific shRNA caused significant decreases in cell proliferation and clonogenic abilities in pancreatic cancer SW1990 and Capan-1 cells. Consistently, the pancreatic cancer cell growth rates were also impaired in xenotransplanted mice. Moreover, wound-healing assay showed that depletion of eIF3a significantly slowed down the wound recovery processes in SW1990 and Capan-1 cells. Transwell migration and invasion assays further showed that cell migration and invasion abilities were significantly inhibited by knockdown of eIF3a in SW1990 and Capan-1 cells. Statistical analysis of eIF3a expression in 140 cases of pancreatic ductal adenocarcinoma samples revealed that eIF3a expression was significantly associated with tumor metastasis and TNM staging. These analyses suggest that eIF3a contributes to cell proliferation and motility in pancreatic ductal adenocarcinoma.

A new interactive image segmentation method used in the multiple myeloma cloning spots image segmentation is presented in the paper. Based on the theory of graph cuts, some pixels are selected as the front object and the background seeds, and the other parts are treated as the unknown region. Then, an energy function is constructed and initialized through K-means, and the minimum cut method is used in the segmentation by energy minimization. Last, the image is eroded and dilated, and the cloning separate parts could be got effectively. For the pixels which may be partitioned wrongly, we use a tool similar to a brush to re-mark the front object or the background, and divide once again. Both subjective the evaluation criteria and the RUMA, evaluation criteria are used to evaluate the method, and the experiment results are satisfactory.

<p><b>BACKGROUND</b>Although the use of hepatitis B immunoglobulin (HBIG) may lead to a significant reduction in recurrent hepatitis B virus (HBV) infection and improve the survival of patients who have undergone liver transplantation (LT) for hepatitis B-related diseases, the recurrence of the disease still remains at a lower level. Different clinical curative effects were observed in patients with the same HBV-related diseases and the same therapy. This study was undertaken to investigate whether the efficacy of HBIG is associated with FCGR3A gene polymorphisms in Chinese liver transplant patients.</p><p><b>METHODS</b>Altogether 77 patients who had received liver transplantation for hepatitis B-related diseases with more than one-year survival after surgery were studied. The recurrence of HBV was characterized by the appearance of HBsAg in serum after the operation. The FCGR3A genotyping was performed using genomic DNA sequencing (ABI 3037). Single nucleotide polymorphism at nucleotide 559 was detected by Polyphred.</p><p><b>RESULTS</b>Of the 77 patients, 14 were complicated with HBV recurrence post-transplant. The FCGR3A at nucleotide 559 TT was observed in 35 (45.5%) subjects, whereas TG in 31 (40.3%) and GG in 11 (14.3%). In the 559G carrier group (n = 42, 54.5%), the risk of HBV recurrence was 9.5%, and 1- and 2-year recurrence-free survival rates were 95.2% and 88.7%, respectively. In the 559G noncarrier group (n = 35, 45.5%), the risk of HBV recurrence was 28.6%, and 1- and 2-year recurrence-free survival rates were 74.3% and 69.3%, respectively. The risk of HBV recurrence and the recurrence-free survival rate were both statistically different between the 559G carrier and noncarrier groups (P < 0.05).</p><p><b>CONCLUSIONS</b>A single nucleotide polymorphism (T/G) at position 559 of the FCGR3A gene was found in Chinese patients. The efficacy of HBIG in prophylaxis of HBV recurrence after LT is associated with the gene polymorphism, so detecting FCGR3A genotypes can be a clinical reference of the HBIG administration.</p>
