The R0 resection rates were 88.9% and 86.1% in the surgery-first and neoadjuvant chemotherapy groups after PSM, respectively (P = 1.000). The median follow-up period was 46.4 mo. The 5-year overall survival rates of the neoadjuvant chemotherapy group and surgery-first group were 50.0% and 65.0% (P = 0.235), respectively, before PSM and 50% and 64.7% (P = 0.192), respectively, after PSM. Multivariate analyses conducted before and after PSM showed that NAC was not a prognostic factor. CONCLUSION Neoadjuvant chemotherapy provides no survival benefit in patients with locally advanced gastric signet-ring cell carcinoma. For resectable gastric signet-ring cell carcinoma, upfront surgery should be the primary therapy. ©The Author(s) 2020. Published by Baishideng Publishing Group Inc.

In clinical practice, the prognosis of liver cancer patients is poor, and the complex reasons contribute to treatment failures, including fibrosis, hepatitis viral infection, drug resistance and metastasis. Thus, screening novel prognostic biomarkers is of great importance for guiding liver cancer therapy. Orosomucoid genes (ORMs) encode acute phase plasma proteins, including orosomucoid 1 (ORM1) and ORM2. Previous studies showed their upregulation upon inflammation, but the specific function of ORMs has not yet been determined, especially in the development of liver cancer. AIM To determine the expression of ORMs and their potential function in liver cancer. METHODS Analysis of the expression of ORMs in different human tissues was performed on data from the HPA RNA-seq normal tissues project. The expression ratio of ORMs was determined using the HCCDB database, including the ratio between liver cancer and other cancers, norssion was negatively correlated with the macrophage infiltration level, CD68, TGFβ1, CTLA4 and PD-1 levels. CONCLUSION The results showed that ORM1 and ORM2 were highly expressed specifically in liver tissues, whereas ORM1 and ORM2 were downregulated in liver tumor tissues. ORM2 is a better prognostic factor for liver cancer. Furthermore, ORM2 is closely associated with cancer-promoting pathways. ©The Author(s) 2020. Published by Baishideng Publishing Group Inc.

Identification of novel prognostic biomarkers and molecular targets is urgently needed. AIM To identify potential key genes associated with tumor microenvironments and the prognosis of HCC. METHODS The infiltration levels of immune cells and stromal cells were calculated and quantified based on the ESTIMATE algorithm. Differentially expressed genes (DEGs) between high and low groups according to immune or stromal scores were screened using the gene expression profile of HCC patients in The Cancer Genome Atlas and were further linked to the prognosis of HCC. These genes were validated in four independent HCC cohorts. Survival-related key genes were identified by a LASSO Cox regression model. RESULTS HCC patients with a high immune/stromal score had better survival benefits than patients with a low score. A total of 899 DEGs were identified and found to be involved in immune responses and extracellular matrices, 147 of which were associated with overall survival. Subsequently, 52 of 147 survival-related DEGs were validated in additional cohorts. Finally, ten key genes (STSL2, TMC5, DOK5, RASGRP2, NLRC3, KLRB1, CD5L, CFHR3, ADH1C, and UGT2B15) were selected and used to construct a prognostic gene signature, which presented a good performance in predicting overall survival. CONCLUSION This study extracted a list of genes associated with tumor microenvironments and the prognosis of HCC, thereby providing several valuable directions for the prognostic prediction and molecular targeted therapy of HCC in the future. ©The Author(s) 2020.

Disturbed microbial milieu in the gastrointestinal tract is central to the pathogenesis of several diseases including antibiotic-associated diarrhea and Clostridioides difficile infection (CDI). Manipulation of this microbial milieu to restore balance by microbial replacement therapies has proven to be a safe and effective treatment for recurrent CDI. There is considerable heterogeneity in various aspects of stool processing and administration for fecal microbiota transplantation (FMT) across different centers globally, and standardized microbioal replacement therapies offer an attractive alternative. The adverse effects associated with FMT are usually mild. selleck compound However, there is paucity of data on long term safety of FMT and there is a need for further studies in this regard. With our increasing understanding of the host-microbiome interaction, there is immense potential for microbial replacement therapies to emerge as a treatment option for several diseases. The role of microbioal replacement therapies in diseases other than CDI is being extensively studied in ongoing clinical trials and it may be a potential treatment option for inflammatory bowel disease, irritable bowel syndrome, obesity, multidrug resistant infections, and neuropsychiatric illnesses. Fecal microbiota transplantation for non-CDI disease states should currently be limited only to research settings. ©The Author(s) 2020. Published by Baishideng Publishing Group Inc.

There are several calculation methods to regulate hypotonic preparations. However, there are no methods that can be used to regulate hypertonic preparations without causing dose-dividing problem. Objective This study aimed to develop a new calculation using basic principle of freezing point depression method (cryoscopic) that can solve hypotonic and hypertonic problems, especially for hypertonic preparations through reducing the levels of additional ingredients. Methods The calculation of Kahar method was successfully obtained by substitution and simplification in the basic principle equation of cryoscopic method, and then evaluated by resolving the problems in 42 sterile formula preparations and compared with White-Vincent method, cryoscopic method, equivalent NaCl method, and milliequivalent method through the analysis of its similarity and reliability.
