Objective:To explore clinical features, diagnosis, localization, and therapeutic strategy of migratory pharyngeal and cervical esophageal foreign bodies.Methods:A total 23 cases of pharyngeal and cervical esophageal migratory foreign bodies were admitted between January 2015 and December 2021. There were 14 females and 9 males with the age ranged from 35 to 82 (55.0±12.7)years. In all the cases, esophageal CT was taken to confirm the esophageal foreign body. Multiplanar reconstruction (MPR) was performed to locate the foreign body from the horizontal, coronal and sagittal dimensions as well as the corrected reconstructed MPR. According to the location of the foreign body, appropriate surgical method was selected.The symptoms, complications, types of foreign body, positioning, surgical methods, and relevant information were recorded.Data were analyzed using the descriptive method and SPSS 25.0 software.Results:The clinical symptoms of 23 migrating esophageal foreign bodies included pharyngodynia (20/23), foreign body sensation (6/23), hoarsenss (1/23), difficulty in turning neck(1/23), difficulty in opening mouth (1/23), fever (7/23), poor appetite (1/23), and abdominal pain (1/23). The foreign bodies included 19 fish bones, 2 wires, 1 embroidery needle and 1 chicken bone. There were 9 cases (39.1%) of foreign bodies located in extraluminal cervical esophagus, 2 cases (8.7%) of foreign bodies located in the muscular layer of the cervical esophagus and 12 cases (52.2%) of foreign bodies located in pharynx. Twenty-one cases of foreign bodies were removed by cervical lateral incision, in which 11 were removed by cervical lateral incision directly, 10 by the second lateral cervical incision after the foreign bodies were accurately located by MPR and/or corrected MPR, 1 foreign body was removed by incision of the pharyngeal mucosa under suspension laryngoscope, 1 foreign body was removed by tracheoscopy. Compared with patients with intraluminal foreign bodies ( n=308) treated in the same period, intake of fishbone [19 (19/23) vs. 133 (82.6% (43.2%, 133/308), OR=7.31] and first visit was more than 24 hours [20(87.0%, 20/23) vs. 77(25.0%, 77/308), OR=17.2] were the significant risk factors of migratory esophageal foreign bodies. Conclusions:MPR and the corrected MPR can accurately locate the migrating pharyngeal and cervical esophageal foreign bodies, by providing more intuitive imaging evidence for doctors, which provide imaging basis for formulation of surgical programs. Foreign bodies in pharyngeal and cervical esophagus need to be treated as soon as possible, otherwise they are easy to migrate, leading lead to serious complications.

OBJECTIVE：To study the effects of Plantago asiatica polysaccharide on the proliferation ，migration and invasion of breast cancer cells ，and to investigate its mechanism preliminarily. METHODS ：Using human breast cancer cell MDA-MB- 231 as subjects ，MTT method was adopted to detect the effects of different concentrations of P. asiatica polysaccharide（8，16，32，64 mg/L）on the cell proliferation ability ，and survival rate of the cells was calculated. Scratch test and Transwell invasion test were used to detect the effects of different concentrations of P. asiatica polysaccharide（8，16 mg/L）on cell migration ability and invasion ability. Western blot assay was used to detect the expression of epithelial-mesenchymal transition （EMT）-related proteins [matrix metalloproteinase- 2（MMP-2），MMP-9，E-cadherin，N-cadherin，vimentin]. RESULTS ：Results of MTT assay showed that survival rate of the cells in 32，64 mg/L P. asiatica polysaccharide groups were significantly lower than control group （P＜0.05 or P＜0.01），so that 8，16 mg/L，which did not affect the cell survival rate ，were used as the follow-up drug concentrations. Compared with control group ，relative mobility （12，24 h），relative invasion rate and relative expression of MMP- 2，MMP-9， N-cadherin and vimentin protein were decreased significantly in 8，16 mg/L P. asiatica polysaccharide groups （P＜0.05 or P＜ 0.01），while relative expression of E-cadherin protein was increased significantly （P＜0.05 or P＜0.01）. CONCLUSIONS ：P. asiatica polysaccharide can inhibit the proliferation of breast cancer cells MDA-MB- 231，and inhibit the migration and invasion of the cells by regulating the expression of metastasis and EMT-related proteins.

Objective:To investigate the changes in gut microbiota diversity with age in elderly people using high-throughput sequencing.Methods:Ninety healthy volunteers were recruited. People who were <60 years old (middle-aged group) were set up as a baseline control group (Age A group), while those aged ≥60 years old were further divided into four groups (60-<70: Age B group, 70-<80: Age C group, 80-<90: Age D group, ≥90: Age E group). Fecal samples were collected to extract DNA. The second-generation sequencing technology was used to amplify and sequence the V3-V4 hypervariable region of 16S rDNA. Bioinformatics analysis was performed to compare the differences in gut microbiota and functional genes among groups.Results:At the phylum level, gut microbiota were composed mainly of Firmicute, Bacteroidetes, Proteobacteria and Actinobacteria in different groups. The proportion of Firmicute was the highest, accounting for over 60%, followed by that of Bacteroidetes. At the genus level, the abundance of Faecalibacterium genus decreased with age. The α diversity analysis showed that the gut microbiota in the elderly of different ages had higher abundance and uniformity, and there was no significant difference among groups. However, the β diversity analysis showed that in community structure there was difference between Age A and Age B groups, and similarity between Age B and Age C groups. Conclusions:The community structure of gut microbiota changed significantly between young and middle-aged people and the elderly over 60 years old. It tended to be relatively stable in people of 60-80 years old, but changed again when they were over 80 years old. Chronic inflammatory diseases, metabolic diseases and tumors in the elderly might be associated with the decrease in Faecalibacterium.

Objective: To investigate the gut microbiota diversity between the elderly supported by institution-based care and home-based care. Methods: Fresh stool samples were collected from 18 aged persons supported by institution-based care (G1 group), 20 aged persons with home-based care (G2 group) and 20 middle-aged and young adults (G3 group). The V3-V4 hypervariable region of 16S rDNA was amplified and sequenced by next generation sequencing technology. Operational taxonomic units (OTUs) were analyzed by QIIME analysis platform for species annotation, diversity analysis, and inter-group difference analysis. Statistical analysis was performed using RStudio software. Results: The top 6 microbiological taxa in the three groups were Firmicute, Bacteroidetes, Proteobacteria, Actinobacteria, Fusobacteria and Verrucomicrobia. The abundance of the Firmicute in the G1 and G2 groups showed significant differences [(61.47±5.58)% vs (76.55±3.64)%, P<0.05]. The G1 and G3 groups had a statistically significant difference in the abundance of the Proteobacteria [(9.59±12.68)% vs (2.15±2.47)%, P<0.05]. The abundance of both Bacteroidetes and Proteobacteria was higher in the G1 group than in the G2 group without significant difference between the two groups. No significant differences in diversity indices (Shannon, Simpson and Chao1) were found between G1 and G2 groups (P>0.05). Results of the NMDS analysis showed that the intra-group differences were greater than inter-group differences in G1 and G2 groups. Conclusions No significant difference in the diversity of gut microbiota was detected between the elderly supported by institution-based care and home-based care, but there were differences in the composition of the predominant gut microbiota.
