Objective To explore the effects and action mechanism of miR-181c-5p on biological behaviors of pros-tate cancer cells.Methods The pathological relationship between BIRC5,miR-181c-5p and prostate cancer was analyzed based on prostate cancer data in TCGA database.The target binding site of miR-181c-5p and BIRC5 was analyzed by miRNA target gene prediction database,and was verified by double luciferase activity assay.The ex-pression of BIRC5 protein in miR-181 c-5p overexpression cells was detected by Western blot.The prostate cancer cells PC3 and DU145 were selected to construct cell line with miR-181c-5p overexpression(miR-181c-5p group)and its negative control(miR-NC group),and qRT-PCR verification was conducted.The cells proliferation[opti-cal density at 450 nm site(OD450 nm)]was detected by CCK-8.Distribution of cell cycles and apoptosis rate were detected by flow cytometry.Expressions of proliferation and apoptosis related proteins were detected by Western blot.The cell line with miR-181c-5p/BIRC5 overexpression was constructed(miR-181c-5p+BIRC5 group).Cells growth,distribution of cell cycles,apoptosis rate and expressions of related proteins were detected by the a-bove methods.Results The expression of BIRC5 was up-regulated in prostate cancer tissues,and it was higher in patients with high tumor invasion,lymph node metastasis and recurrence.Patients exhibiting high expression of BIRC5 demonstrated poor survival rates.The expression of miR-181c-5p was down-regulated in prostate cancer tis-sues.The level of miR-181c-5p was negatively correlated with BIRC5 level,and miR-181c-5p could inhibit BIRC5 expression.In PC3 and DU145,miR-181c-5p level in miR-181c-5p group was higher than that in miR-NC group(P＜0.05);OD450 nm and percentage of S-phase cells were lower than those in miR-NC group(P＜0.05),per-centage of cells in G0/G1 phase;apoptosis rate and expressions of BAX,caspase-3 and PARP proteins were higher than those in miR-NC group(P＜0.05);expressions of CDK2,CCNB1 and BCL-2 proteins were lower than those in miR-NC group(P＜0.05).The expression of BIRC5 protein and OD450 nm in miR-181 c-5p+BIRC5 group were higher than those in miR-181c-5p group(P＜0.05),percentage of cells in G0/G1 phase was lower than that in miR-181c-5p group(P＜0.05);percentage of S-phase cells was higher than that in miR-181c-5p group(P＜0.05);apoptosis rate was lower than that in miR-181c-5p group(P＜0.05);expressions of CDK2,CCNB1 and BCL-2 proteins were higher than those in miR-181c-5p group;expressions of BAX,caspase-3 and PARP proteins were lower than those in miR-181 c-5p group.Conclusion miR-181-5p can inhibit the proliferation of human pros-tate cancer cells by targeting BIRC5,block cells in G0/G,phase and promote cells apoptosis.

Objectives:To explore the spatial distribution characteristics, trend changes, and spatial clustering of esophageal cancer among residents in China at the county (city, district) scale, a spatial epidemiological approach was used, with the aim of providing localized evidence for the prevention and treatment of esophageal cancer in China.Methods:The data source was the incidence (crude rate) and mortality (crude rate) of esophageal cancer from 2005 to 2016 in the 2008-2019 edition of China Cancer Registration Annual Report published by the National Cancer Center. The Joinpoint model was used for time trend analysis. The tumor registration area in 2016 was selected as the study area for spatial feature analysis, with a total of 487 counties (cities and districts), covering 27.6% of the national population. Spatial autocorrelation analysis was performed to reveal spatial distribution characteristics by using Arcgis 10.6 software, and spatial scanning statistics was used to analyze spatial clustering characteristics by using SaTScan 9.5 software. The log-likelihood ratio ( LLR) and relative risk ( RR) were calculated in different windows, and the region with the largest LLR value represented the most likely cluster. Results:From 2005 to 2016, the incidence and mortality rate of esophageal cancer in China showed a trend of increasing at first and then decreasing. The incidence and mortality rate of esophageal cancer in 2016 were characterized by spatial positive correlation. High incidence and high mortality were mainly concentrated in the areas through which the Huaihe River flowed. The primary clusters (taking high incidence rate as an example LLR=6 374.41, RR=2.37, P＜0.001) were mainly distributed in Jiangsu, Anhui and Shandong in eastern China and eastern Henan and southern Hebei in central China, and secondary clusters (taking high incidence rate as an example LLR=1 971.19, RR=1.91, P＜0.001) in Gansu, Ningxia Hui Autonomous Region, Shaanxi, Sichuan and other central and western regions. Conclusions:The incidence and mortality of esophageal cancer in China have decreased since 2010. The disease burden of esophageal cancer has obvious spatial differences, and measures should be taken according to local conditions in high-risk cluster areas such as the Huaihe River basin.

Objective:To explore the optimal ratio of dihydrotestosterone and hydroxyflutamide (hereinafter referred to as DH), construct a dual release system of androgen and its antagonist, and analyze the application effect of this system in the repair of full-thickness burn wounds in mice.Methods:This study was an experimental study. The HaCaT cells were divided into blank group (without drug culture), low baseline group, medium baseline group, and high baseline group according to the random number table (the same grouping method below), and the last three groups of cells were cultured by adding three different ratios of DH. Under a medium ratio, the mass of dihydrotestosterone in the three baseline groups from low to high was 1.4, 2.8, and 4.0 μg, respectively, and the mass of hydroxyflutamide was 1.2, 1.6, and 2.0 μg, respectively. On this basis, under a small ratio, the mass of dihydrotestosterone was reduced by half and the mass of hydroxyflutamide was increased by half; under a large ratio, the mass of dihydrotestosterone was increased by half and the mass of hydroxyflutamide was reduced by half. After culture of 2 days, the cell proliferation level was detected by cell counting kit 8 ( n=4). Sixteen 6-8-week-old male BALB/c mice were used to establish a full-thickness burn wound on the back and divided into blank group, small ratio group, medium ratio group, and large ratio group, with 4 mice in each group. On post injury day (PID) 7, normal saline containing different ratios of DH was locally dropped to the wounds of mice in the last three groups of mice (the total mass of DH in the three ratio groups from small to large was 127.5, 165.0, and 202.5 μg, respectively, and the mass ratios of dihydrotestosterone to hydroxyflutamide (hereinafter referred to as drug mass ratio) were 8∶9, 8∶3, and 8∶1, respectively), afterwards, the administration was repeated every 48 hours until PID 27; normal saline was dropped to the wound of mice in blank group at the aforementioned time points. The wound healing status on PID 0 (immediately), 7, 14, 21, and 28 was observed, and the wound healing rates on PID 7, 14, 21, and 28 were calculated ( n=4). On PID 28, the wound tissue was taken, which was stained with hematoxylin and eosin for observing re-epithelialization and with Masson for observing collagen fibers, and the proportion of collagen fibers was analyzed ( n=3). Twenty 6-8-week-old male BALB/c mice were used to establish a full-thickness burn wound on the back and divided into ordinary scaffold group, small proportion scaffold group, medium proportion scaffold group, and large proportion scaffold group (with 5 mice in each group). On PID 7, the wound was continuously dressed with a polycaprolactone scaffold without drug and a polycaprolactone scaffold containing DH with a drug mass ratio of 1∶3, 1∶1, or 3∶1 (i.e. the dual release system of androgen and its antagonist, with total mass of DH being about 1.7 mg) prepared by using electrospinning technology until the end of the experiment. Histopathological analyses of tissue ( n=3) at the same time points as those in the previous animal experiment were performed. On PID 7 and 14, the wound exudates were collected and the relative abundance of bacterial communities was analyzed using 16S ribosomal RNA high-throughput sequencing ( n=3). Results:After culture of 2 days, under a small ratio, the proliferation levels of HaCaT cells in low baseline group and high baseline group were significantly higher than the level in blank group ( P<0.05). As the time after injury prolonged, the wounds of all four groups of mice continued to shrink. On PID 14, the wound healing rate of mice in large ratio group was 72.5% (61.7%, 75.1%), which was close to 53.3% (49.5%, 64.4%) in blank group ( P>0.05); the wound healing rates of mice in small and medium ratio groups were 74.2% (71.0%, 84.2%) and 70.4% (65.1%, 74.4%), respectively, which were significantly higher than the rate in blank group (with both Z values being -2.31, P<0.05). On PID 21, the wound healing rate of mice in small ratio group was significantly higher than that in blank group ( Z=-2.31, P<0.05). On PID 28, the wounds of mice in the three ratio groups were completely re-epithelialized and the epidermis was thicker than that in blank group; compared with that in blank group, the collagen fiber content in the wound tissue of mice in the three ratio groups was higher and arranged more orderly, and the proportions of collagen fibers in the wound tissue of mice in small and large ratio groups were significantly increased ( P<0.05). On PID 28, the wounds of mice in ordinary scaffold group were partially epithelialized, while the wounds of mice in the three proportion scaffold groups were almost completely epithelialized. Among them, the wounds of mice in small proportion scaffold group had the thickest epidermis. The proportion of collagen fibers in the wound tissue of mice in small proportion scaffold group was significantly increased compared with that in ordinary scaffold group ( P<0.05). On PID 7, the bacterial communities with high relative abundance in the wound exudation of mice in the four groups included bacteria of Corynebacterium, Staphylococcus, and Rhodococcus. On PID 14, the bacterial communities with high relative abundance in the wound exudation of mice in the four groups included bacteria of Stenotrophomonas, Rhodococcus, and Staphylococcus, and the number of bacterial species in the wound exudation of mice in the three proportion scaffold groups was more than that in ordinary scaffold group. Conclusions:When the drug mass ratio is relatively small, DH has the effect of promoting the proliferation of HaCaT cells. The ratio of 8∶9 is the optimal mass ratio of dihydrotestosterone to hydroxyflutamide, and DH with this mass ratio can promote re-epithelialization and collagen deposition of full-thickness burn wounds in mice, and promote wound healing. The constructed dual release system of androgen and its antagonist with DH in a 1∶3 drug mass ratio contributes to the re-epithelialization and collagen deposition of the full-thickness burn wounds in mice, and can improve the diversity of wound microbiota.
