BACKGROUND The expression of brain cytoplasmic RNA1(BCYRN1)is linked to the clinicopathology and prognosis of several types of cancers,among which hepatocellular carcinoma(HCC)is one of the most frequent types of cancer worldwide.AIM To explore the prognostic value and immunotherapeutic potential of BCYRN1 in HCC by bioinformatics and meta-analysis.METHODS Information was obtained from the Cancer Genome Atlas database.First,the correlation between BCYRN1 expression and prognosis and clinicopathologic characteristics of HCC patients was explored.Univariate and multivariate regression analyses were employed to examine the relationship between BCYRN1 and HCC prognosis.Secondly,potential functions and pathways were explored by means of enrichment analysis of differentially-expressed genes.The relationships between BCYRN1 expression and tumor microenvironment,immune cell infiltration,immune checkpoint,drug sensitivity and immunotherapy effect were also investigated.Finally,three major databases were searched and used to conduct a meta-analysis on the relationship between BCYRN1 expression and patient prognosis.RESULTS BCYRN1 expression was significantly higher in HCC compared to normal tissues and was linked to a poor prognosis and clinicopathological characteristics.Enrichment analysis showed that BCYRN1 regulates the extracellular matrix and transmission of signaling molecules,participates in the metabolism of nutrients,such as proteins,and participates in tumor-related pathways.BCYRN1 expression was linked to the tumor microenvironment,immune cell infiltration,drug sensitivity and the efficacy of immunotherapy.Furthermore,the meta-analysis in this study showed that BCYRN1 overexpression was related to a worse outcome in HCC patients.CONCLUSION Overexpression of BCYRN1 relates to poor prognosis and may be a potential prognostic factor and immunotherapeutic target in HCC. 展开更多

BACKGROUND Conventional Billroth Ⅱ(BⅡ) anastomosis after laparoscopic distal gastrectomy(LDG) for gastric cancer(GC) is associated with bile reflux gastritis, and Roux-enY anastomosis is associated with Roux-Y stasis syndrome(RSS). The uncut Rouxen-Y(URY) gastrojejunostomy reduces these complications by blocking the entry of bile and pancreatic juice into the residual stomach and preserving the impulse originating from the duodenum, while BⅡ with Braun(BB) anastomosis reduces the postoperative biliary reflux without RSS. Therefore, the purpose of this study was to compare the efficacy and safety of laparoscopic URY with BB anastomosis in patients with GC who underwent radical distal gastrectomy.AIM To evaluate the value of URY in patients with GC.METHODS PubMed, Embase, Web of Science, Cochrane Library, Chinese National Knowledge Infrastructure, Wanfang, Chinese Biomedical Database, and VIP Database for Chinese Technical Periodicals(VIP) were used to search relevant studies published from January 1994 to August 18, 2021. The following databases were also used in our search: Clinicaltrials.gov, Data Archiving and Networked Services, the World Health Organization International Clinical Trials Registry Platform Search Portal(https://www.who.int/clinical-trials-registry-platform/the-ictrp-search-portal), the reference lists of articles and relevant conference proceedings in August 2021. In addition, we conducted a relevant search by Reference Citation Analysis(RCA)(https://www.referencecitationanalysis.com). We cited highquality references using its results analysis functionality. The methodological quality of the eligible randomized clinical trials(RCTs) was evaluated using the Cochrane Risk of Bias Tool, and the non-RCTs were evaluated using the Newcastle-Ottawa scale. Statistical analyses were performed using Review Manager(Version 5.4).RESULTS Eight studies involving 704 patients were included in this meta-analysis. The incidence of reflux gastritis [odds ratio = 0.07, 95% confidence interval(CI): 0.03-0.19, P < 0.00001] was significantly lower in the URY group than in the BB group. The pH of the postoperative gastric fluid was lower in the URY group than in the BB group at 1 d [mean difference(MD) =-2.03, 95%CI:(-2.73)-(-1.32),P < 0.00001] and 3 d [MD =-2.03, 95%CI:(-2.57)-(-2.03), P < 0.00001] after the operation. However,no significant difference in all the intraoperative outcomes was found between the two groups.CONCLUSION This work suggests that URY is superior to BB in gastrointestinal reconstruction after LDG when considering postoperative outcomes. 展开更多

Olfactory bulb tissue transplantation inhibits P2X2/3 receptor-mediated neuropathic pain. However, the olfactory bulb has a complex cellular composition, and the mechanism underlying the action of purified transplanted olfactory ensheathing cells(OECs) remains unclear. In the present study, we microencapsulated OECs in alginic acid, and transplanted free and microencapsulated OECs into the region surrounding the injured sciatic nerve in rat models of chronic constriction injury. We assessed mechanical nociception in the rat models 7 and 14 days after surgery by measuring paw withdrawal threshold, and examined P2X2/3 receptor expression in L4–5 dorsal root ganglia using immunohistochemistry. Rats that received free and microencapsulated OEC transplants showed greater withdrawal thresholds than untreated model rats, and weaker P2X2/3 receptor immunoreactivity in dorsal root ganglia. At 14 days, paw withdrawal threshold was much higher in the microencapsulated OEC-treated animals. Our results confirm that microencapsulated OEC transplantation suppresses P2X2/3 receptor expression in L4–5 dorsal root ganglia in rat models of neuropathic pain and reduces allodynia, and also suggest that transplantation of microencapsulated OECs is more effective than transplantation of free OECs for the treatment of neuropathic pain. 展开更多

Exogenous substance P accelerates wound healing in diabetes,but the mechanism remains poorly understood.Here,we established a rat model by intraperitoneally injecting streptozotocin.Four wounds(1.8 cm diameter) were drilled using a self-made punch onto the back,bilateral to the vertebral column,and then treated using amniotic membrane with epidermal stem cells and/or substance P around and in the middle of the wounds.With the combined treatment the wound-healing rate was 100% at 14 days.With prolonged time,type I collagen content gradually increased,yet type III collagen content gradually diminished.Abundant protein gene product 9.5-and substance P-immunoreactive nerve fibers regenerated.Partial nerve fiber endings extended to the epidermis.The therapeutic effects of combined substance P and epidermal stem cells were better than with amniotic membrane and either factor alone.Our results suggest that the combination of substance P and epidermal stem cells effectively contributes to nerve regeneration and wound healing in diabetic rats. 展开更多
