Abstract
Objective: To investigate the concern about pollen broadcasting in Chinese population from multiple dimensions and to understand the information about allergic rhinitis (AR) in China by analyzing related factors. Methods: From March 1 to September 30, 2022, a large-scale multi-center cross-sectional survey was conducted based on the Questionnaire Star platform in 21 Chinese hospitals. A total of 7 056 subjects from 7 regions in China: Northeast, North, East, Central, South, Southwest, and Northwest China were included. Basic characteristics (including social demographic characteristics and disease characteristics of AR patients), concern about pollen broadcasting, the willingness of pollen-induced AR (PiAR) patients to receive pollen broadcasting, and the treatment satisfaction rate of AR patients were collected. The chi-square test, multivariate linear regression model, and Logistic regression analysis were used to analyze the concern about pollen broadcasting in the Chinese population and related factors from multiple dimensions. Results: Among 7 056 subjects, 23.02% were concerned about pollen broadcasting. Among 3 176 self-reported AR and 1 019 PiAR patients, 25.60% and 39.16% were concerned about pollen broadcasting, respectively, which was higher than that of non-AR or non-PiAR subjects (χ2 value was 21.74 and 175.11, respectively, both P<0.001). Among AR patients, the proportion of spring and autumn allergen-positive patients concerned about pollen broadcasting was higher than that in perennial allergen-positive patients (χ2 value was 20.90 and 19.51, respectively, both P<0.001). The proportion of AR patients with asthma, sinusitis, allergic conjunctivitis, and cardiovascular and cerebrovascular diseases was higher than those without complications (χ2 value was 50.83, 21.97, 56.78, 7.62, respectively, all P<0.05). The proportion of AR patients in North China who could find pollen broadcasting locally was 31.01%, significantly higher than those in other regions (all P<0.05). Multivariate linear regression model analysis showed that among PiAR patients, those with higher per capita household income and higher AR disease cognition levels had been concerned about pollen broadcasting in the past, and those complicated with allergic conjunctivitis had stronger intention to receive pollen broadcasting (B value was 0.24, 0.13, 0.66, 0.47, respectively, all P<0.05). The higher the disease cognition level of PiAR patients, the stronger their willingness to actively participate in treatment (R2=0.72, P<0.001). Only 18.89% of AR patients felt satisfied with the treatment effect. Logistic regression analysis showed that in AR patients, the treatment satisfaction rate was significantly higher among those concerned about pollen broadcasting compared to those who were not (OR=1.83, P<0.001). Conclusions: Currently, the dissemination of pollen broadcasting in China is hindered by various factors such as disease cognition level. The treatment satisfaction among AR patients remains unsatisfactory.

Abstract
BACKGROUND With recent improvements in surgical technique, oncological outcomes of low rectal cancer have improved over time. But the QoL impairment as a result of anal functional disorder cannot be ignored. And the incidence of anastomosis-related complications cannot be ignored. To address these problems, a personal technique for pull-through coloanal anastomosis (parachute-like intussuscept pull-through anastomosis) was introduced and evaluated. This technique can relatively reduce surgical complications, minimize the impact of anal function, and obviate a colostomy creation. METHODS Between June 2020 and April 2021, 14 consecutive patients with rectal cancer underwent laparoscopic-assisted resection of rectal cancer in our hospital. Parachute-like pull-through anastomosis method was performed in all patients. Anal function, perioperative details, and postoperative outcomes were analyzed. RESULTS The mean (SD) operative time of first stage was 282.1 min (range 220-370) with an average estimated blood loss of 90.3 mL (range 33-200). And the mean (SD) operative time of second was 46 min (range 25-76) with an average estimated blood loss of 16.1 mL (range 5-50). Wexner scores declined significantly during the median follow-up of 18 months. Four postoperative anastomosis-related complications occurred in 14 patients, including perianastomotic abscess: 1 case (7%), anastomotic stricture: 1 case (7%), and colonic ischemia of the exteriorized colonic segment: 2 cases (14%). CONCLUSION The results suggest that the method can facilitate safe and easy completion of coloanal anastomosis, using parachute-like pull-through anastomosis, with acceptable anal function.

Abstract
This study explored the effects of Lactiplantibacillus plantarum (previously Lactobacillus plantarum) BW2013 on mucosal integrity and gut microbiota of mice with dextran sulfate sodium (DSS)-induced colitis. The results show that the clinical symptoms in DSS-modelled ulcerative colitis (UC) were improved by L. plantarum BW2013 via decreasing disease activity index scores and suppressing inflammatory cell infiltration. Furthermore, L. plantarum BW2013 decreased the levels of diamine oxidase activity, myeloperoxidase, and D-lactic acid. The mRNA expression of ZO-1, occludin, and claudin-1 was upregulated by L. plantarum BW2013, which also increased IL-10 and reduced TNF-α, IL-1β, and IL-6 in the colon. 16S rDNA sequencing showed that L. plantarum BW2013 enhanced α-diversity. L. plantarum BW2013 upregulated significantly the abundance of unidentfied Lachnospiraceae, Lactococcus, Rikenella, Lactobacillus, and Odoribacter, which had an inhibitory effect on inflammation and a protective effect on the integrity of the mucosa. These results demonstrate that L. plantarum BW2013 alleviates DSS-modelled UC by protecting mucosal integrity and ameliorating the composition of gut microbiota.

Abstract
Despite the high mutation frequencies of KRAS, NRAS, and BRAF in colorectal cancer (CRC), there are no effective and reliable inhibitors for these biomarkers. Protocadherin-7 (PCDH7) is regarded as a potentially targetable surface molecule in cancer cells and plays an important role in their proliferation, metastasis, and drug resistance. However, the roles and underlying mechanisms of PCDH7 in CRC remain unclear. In the current study, we found that different colorectal cancer cells expressed PCDH7 over a wide range. The levels of PCDH7 expression were positively associated with cell proliferation and drug resistance in CRC cells but negatively correlated with the potential for cell migration and invasion. Our data indicated that PCDH7 mediated the resistance of CRC cells to ABT-263 (a small-molecule Bcl-2 inhibitor that induces apoptosis) by inhibiting cell apoptosis, which was supported by the downregulation of caspase-3, caspase-9, and PARP cleavage. We found that PCDH7 effectively promoted Mcl-1 expression at both mRNA and protein levels. Furthermore, PCDH7 activated the Wnt signaling pathway, which was confirmed by the increase in β-catenin and c-Myc expression. Finally, and notably, S63845, a novel Mcl-1 inhibitor, not only effectively attenuated the inhibitory effect of PCDH7 on cell apoptosis induced by ABT-263 in vitro but also sensitized PCDH7-overexpressed CRC cell-derived xenografts to ABT-263 in vivo. Taken together, although PCDH7 inhibited the migration and invasion of CRC cells, it could facilitate the development of drug resistance in colorectal cancer cells by positively modulating Mcl-1 expression. The application of the Mcl-1 inhibitor S63845 could be a potential strategy for CRC chemotherapy, especially in CRC with high levels of PCDH7.

Abstract
Recent studies have indicated that changes in the tumor microenvironment, such as hypoxia, result in the discrepant expression of noncoding small RNA tRNA-derived fragments (tRFs), affecting the phenotype of tumor metastasis. The biological function of tRFs in tumors has attracted increasing attention, but the mechanism by which tRFs mediate tumor metastasis has not been clarified. The direct regulatory relationship between tRFs and lncRNAs and the mechanism by which noncoding RNAs regulate alternative splicing are still unknown. In this study, the mechanism of tRF-mediated SMC1A alternative splicing and regulation of colon cancer metastasis was studied from multiple dimensions of cell, molecule, animal and clinical. Our present studies revealed that tRF-20-M0NK5Y93 inhibits colon cancer metastasis and that there is a significant correlation between the expression of tRFs, metastasis-associated lung adenocarcinoma transcript 1 (MALAT-1), and SRSF2 through complete transcriptional sequencing and bioinformatics. Mechanistic investigations indicated that tRFs could regulate the expression of MALAT-1 by binding to specific sites on MALAT-1. MALAT1, which is a long noncoding RNA (lncRNA), regulates alternative splicing of (structural maintenance of chromosomes 1A) SMC1A by interaction with SRSF2, resulting in discrepant expression of various isoforms, SMC1A001, SMC1A201, SMC1A005, and SMC1A003. Our findings revealed the interaction between different types of noncoding RNAs on alternative splicing, which is expected to be a novel potential therapeutic target.

Abstract
Hypoxia plays a key role in colorectal cancer (CRC) metastasis, but its underlying mechanism remains largely unknown. Dicer1, an RNase, has been considered as a tumor regulator in many tumors. However, whether Dicer1 affects CRC progression under hypoxia remains uncertain. In this study, we found that Dicer1 expression was induced by hypoxia in CRC cells and it mediates hypoxia-induced CRC cell progression. Furthermore, we found that the expression of tRF-20-MEJB5Y13, a small non-coding RNA derived from tRNA, was increased under hypoxic conditions, and its upregulation by Dicer1 resulted in hypoxia-induced CRC cell invasion and migration. These results advance the current understanding of the role of Dicer1 in regulating hypoxia signals and provide a new pathway for the development of therapeutic interventions for inhibiting cancer progression.

Abstract
tRNA-derived fragments (tRFs) are derived from corresponding tRNAs and have been shown by several studies to be novel biological markers for tumour diagnosis and therapy. However, until now, the effects of tRFs on the progression of colorectal cancer (CRC) and especially on the epithelial-to-mesenchymal transition (EMT) have remained unknown. Our study aimed to assess CRC-related tRFs and examine the effects of key tRFs on CRC progression and related mechanisms. After hypoxic treatment, tRF sequencing and real-time PCR assays were performed to identify key tRFs. Then, functional tests were designed to verify the effects and evaluate the mechanism after cell transfection under normoxic conditions. A total of 14 tRFs were differentially expressed in the hypoxia and control groups. Based on the results of PCR assay verification and conditional selection, tRF-20-M0NK5Y93 could be a promising target for exploration, as its expression was significantly lower under hypoxic conditions than under control conditions. tRF-20-M0NK5Y93 inhibited CRC cell migration and invasion partly by targeting Claudin-1, an EMT-related molecule. The results of the present study suggest that tRF-20-M0NK5Y93 promotes CRC cell migration and invasion partly by regulating Claudin-1 during EMT.

Abstract
One unusual aromatic monacolin analog, aromonacolin A (1), was isolated from the ethanolic extract of Monascus purpureus-fermented rice. Its structure was elucidated by extensive spectroscopic (HRESIMS, (1)H NMR, (13)C NMR, HSQC, HMBC, and NOESY) and chemical methods. The absolute configuration of the C-6 secondary alcohol was deduced via the circular dichroism data of the in situ formed [Rh(2)(OCOCF(3))(4)] complex.

Abstract
OBJECTIVE To study the extraction technology of flavonoids from Cynomorium songaricum by supercritical CO2 extraction. METHODS The effects of pressure, temperature, time, concentration of alcohol, dosage of chemical preparation, flux of CO2 and particle size were studied by single factor analysis and orthogonal test. RESULTS The optimized conditions were as follows: particle size 60 - 80 sieve mesh, the pressure was 30 MPa, the temperature was 50 degrees C, the time was 75 min, concentration of alcohol was 50%, entrainment rate was 8%, flux of CO2 was 5 mL/min. The total flavonoids yield could reach 21.18% under the above conditions. CONCLUSION This method is simple, rapid and higher extraction yield, so it is suitable for the extraction of flavonoids from Cynomorium songaricum.
