Objective: To investigate the changes of microorganisms and metabolites in joint effusion of patients with Rheumatoid arthritis(RA), Osteoarthritis(OA) and Urarthritis(UA). To provide new ideas for the study of the effect of microbiota on the pathogenesis of arthritis. Methods: Joint effusion samples were collected from 20 patients with RA, 20 patients with OA, and 20 patients with UA. 16S rRNA gene sequencing and untargeted ultra-high performance Liquid chromatography-mass spectrometry(LC-MS) were used to explore the differences in microorganisms and metabolites among the three groups. Pearson correlation analysis was used to detect the correlation between effusion microbiota and metabolites. Results: There were differences in microbial diversity and microbiota composition among the three groups. Combined with VIP>1 from OPLS-DA andP<0.05 from two-tailed Students t-test, 45 differential metabolites(Between RA and OA groups), 38 differential metabolites(Between UA and OA groups) and 16 differential metabolites(Between RA and UA groups), were identified. GO analysis and KEGG pathway analysis showed that the differential metabolic pathways among the three groups were mainly concentrated in citric acid cycle(TCA cycle), nucleotide metabolism, amino acid metabolism and glycolysis pathway. Correlation analysis of joint effusion microbiota and metabolites suggested that bacteria enriched in the three groups of joint effusion, such asPrevotella,Clostridium ruminosus,Prevotellaceae＿UCG-001, were related to many key metabolites such as lysozyme, uric acid, glucose, and L-glutamine. Conclusion This study shows that there are a variety of bacterial flora in joint cavity effusion of RA, OA, and UA patients, and the differential metabolites produced by them are involved in the pathogenesis of the three types of arthritis by affecting a variety of metabolic pathways.

Objective : To investigate the expression of genes and proteins in the peripheral blood mononuclear cell ( PBMC) cystine / glutamate antiporter system (System Xc-) / glutathione ( GSH) / glutathione peroxidase 4 ( GPX4) ferroptosis pathway and its influence on inflammatory factors in patients with rheumatoid arthritis ( RA) ． Methods : 30 patients with RA and 30 healthy participants were enrolled．PBMCs were isolated using Ficoll-hypaque density gradient centrifugation．The cells were categorized into the healthy control，RA，ferroptosis inhibitor，ferroptosis in- ducer group．The cell viability was checked using the cell counting kit-8 ( CCK-8) method．Intracellular Fe2 + rela- tive fluorescence intensity and reactive oxygen species (ROS) levels were detected using the FerroOrange and Di- hydroethidium (DHE) fluorescent probes，respectively．Western blot and real-time quantitative PCR (qPCR) de- tected the expression of nuclear factor erythroid 2-related factor 2 ( Nrf2 ) ，solute carrier family 7 member 11 (SLC7A11) ，GPX4 proteins and mRNA．And the flow cytometry quantified the levels of tumor necrosis factor α (TNF-α) ，Interleukin (IL) -1，and IL-6 in the supernatant of each cell group. Results : Compared to the healthy control group，the RA group showed a significantly increased Fe2 + concentration and elevated ROS levels，reduced expression of Nrf2，SLC7A11 and GPX4 proteins and mRNA，and increased contents of TNF-α , IL-1 and IL-6 in PBMC supernatant，and the differences were statistically significant．The concentration of Fe2 + and ROS levels in the inhibitor group were lower than those in the RA group，the proteins expressions of Nrf2，SLC7A11 and GPX4 increased，the mRNA expressions of SLC7A11 and GPX4 increased，the content of IL-6 in the PBMC supernatant decreased but the content of TNF-α increased，and the differences were statistically significant．In contrast，the in- ducer group，when compared to the RA group，displayed increased ROS levels，reduced expression of SLC7A11 protein and mRNA and decreased expression of Nrf2 protein，and the contents of TNF-α and IL-1 in the PBMC su- pernatant increased，but the expression of GPX4 protein increased ，and the differences were statistically signifi- cant．The inducer group，compared to the RA group，showed increased cell viability，and the difference was statis- tically significant (P＜0. 000 1) ． Conclusion The presence of ferroptosis in PBMC in RA patients，inhibiting or inducing PBMC ferroptosis in RA patients，will inhibit or promote the secretion of inflammatory factors．Inhibition of PBMC ferroptosis in RA patients may be helpful in the treatment of RA.

Objective:To investigate the neural mechanism of long-term exposure to high altitudes environment on the processing stage of perceptual closure.Methods:A cross-sectional study was conducted. Thirty college students who first entered the plateau area (at an altitude of 3 658 m) and had lived in high-altitude areas for two years were selected as high altitude group (HA group), and 29 college students matched in age, gender and education level who had never been to the plateau area were selected as sea level group (SL group). The differences of basic physiological parameters were compared between the two groups.The face pairwise comparison paradigm was applied in the subjects of the two groups and the differences between the two groups were compared by event-related potentials (ERPs) technology. SPSS 22.0 software was used for statistical analysis, and the mean ± standard deviation was used for statistical description. Independent sample t test was used for comparison of physiological data between the two groups, and repeated measurement variance analysis was used for ERP data. Results:The physiological results revealed that the HA group had a higher pulse rate((86.71±10.82)/min, (75.97±11.28)/min ; t=-3.19, P=0.002) and diastolic blood pressure than the SL group ((75.93±9.19)mmHg, ( 68.59±11.42) mmHg ; t=-3.20, P=0.002). The oxygen saturation level was significantly lower than that of SL group ((90.77±2.25)%, (98.31±1.56) %) ; t=14.00, P<0.001). In the face pairwise comparison paradigm test, the main effect of P1 latency of ERP was significant.Compared with SL group, HA group showed significantly shortened latency of P1 ((105.10±15.59) ms, (128.35±14.40)ms, P<0.001). The main effect of group of N170 amplitude was significant, HA group was larger than that of SL group((-7.57±3.83) μV, ( -5.11±3.26) μV, P=0.005). The interaction effect between group and hemisphere of NCL amplitude was significant ( F(1, 57)=9.72, P=0.003). Simple effect test showed that the amplitude on the right hemisphere of SL group was significantly larger than that on the left hemisphere((0.46±1.31) μV), (1.16±1.33) μV ). The latency of P1 was significantly correlated with heart rate( r=-0.46, P<0.01), oxygen saturation level( r=0.64, P<0.01) and diastolic blood pressure( r=-0.26, P=0.049). Conclusion:After long-term exposure to high altitude, the neural response related to early visual perception is faster. More psychological resources are recruited during the face structural encoding stage. Contra-lateral compensating effect appeares in the stage of perceptual closure.

The changing value of above indicators of 304 gastric cancer patients in the modeling group during neoadjuvant chemotherapy were 1.4 cm 2/m 2(range, ?31.0?35.1 cm 2/m 2), 0.2 cm 2/m 2(range, ?23.5?32.6 cm 2/m 2), ?0.1 cm 2/m 2(range, ?18.2?15.9 cm 2/m 2), ?26.2 μg/L(range, ?933.5?89.9 μg/L), ?64.9 U/mL(range, ?992.1?178.6 U/mL), ?0.3 kg/m 2(range, ?9.7?7.1 kg/m 2), 0.9(range, ?27.1?38.2), 0.0±0.8, respec-tively. (2) Follow-up and survival of patients: 284 of 304 patients in the modeling group were followed up for 3 to 130 months, with a median follow-up time of 36 months. During follow-up, 130 cases died of tumor recurrence and metastasis and 9 cases died of non-tumor causes. The 5-year overall survival rate was 54.6%. Fifty-two of 58 patients in the validation group were followed up for 2 to 91 months, with a median follow-up time of 29 months. During follow-up, 21 cases died with the 5-year overall survival rate of 63.8%. (3) Analysis of risk factor affecting prognosis of patients in modeling group: results of univariate analysis showed that the postoperative pathological type and postoperative pathological staging were related factors affecting 5-year overall survival rate [ hazard ratio=1.685, 2.619, 95% confidence interval(CI): 1.139?2.493, 1.941?3.533, P<0.05] and 5-year progression free rate survival of 304 gastric cancer patients in the modeling group after radical gastrectomy ( hazard ratio=1.468, 2.577, 95% CI: 1.000?2.154, 1.919?3.461, P<0.05). Results of multivariate analysis showed that the postoperative pathological type and postoperative pathological staging were independent influencing factors for 5-year overall survival rate of 304 gastric cancer patients in the modeling group after radical gastrectomy ( hazard ratio=1.508, 2.287, 95% CI: 1.013?2.245, 1.691?3.093, P<0.05) and the postoperative patholo-gical staging was an independent influencing factor for 5-year progression free survival rate of 304 gastric cancer patients in the modeling group after radical gastrectomy ( hazard ratio= 2.317,95% CI: 1.719?3.123, P<0.05). (4) Construction and comparison of prognostic prediction models: the area under curve (AUC) of prognostic prediction model of subcutaneous adipose index changing value, visceral adipose index changing value, carcinoembryonic antigen changing value, CA19-9 changing value, body mass index changing value, prognostic nutritional index changing value, modified systemic inflammation score changing value for 304 gastric cancer patients in the modeling group were 0.549(95% CI: 0.504?0.593), 0.501(95% CI: 0.456?0.546), 0.566(95% CI: 0.521?0.610), 0.519(95% CI: 0.474?0.563), 0.588(95% CI: 0.545?0.632), 0.553(95% CI: 0.509?0.597), 0.539(95% CI: 0.495?0.584). The AUC of prognostic prediction model of muscle index changing value was 0.661(95% CI: 0.623?0.705) with significant differences to the AUC of prognostic predic-tion model of subcutaneous adipose index changing value, visceral adipose index changing value, carcinoembryonic antigen changing value, CA19-9 changing value, body mass index changing value, prognostic nutritional index changing value, modified systemic inflammation score changing value, respectively ( Z=3.960, 5.326, 3.353, 4.786, 2.455, 3.448, 3.987, P<0.05). The optimum cut-off value was 0.7 cm 2/m 2 for prognostic prediction model of muscle index changing. Kaplan-Meier survival curve showed there were significant differences of overall survival and progression free survival for gastric cancer patients with subcutaneous adipose index changing value <0.7 cm 2/m 2 and ≥0.7 cm 2/m 2 in the modeling group ( χ2 =27.510, 21.830, P<0.05). The nomogram prognostic prediction model was cons-tructed based on 3 prognostic indicators including muscle index change value combined with postoperative pathological type and postoperative pathological staging and the AUC of nomogram prognostic prediction model were 0.762(95% CI: 0.708?0.815) and 0.788(95% CI: 0.661?0.885) for the modeling group and the validation group, respectively. The AUC of postoperative pathological staging prognostic prediction model were 0.706(95% CI: 0.648?0.765) and 0.727(95% CI: 0.594?0.835)for the modeling group and the validation group, respectively. There were significant differences of the AUC between the nomogram prognostic prediction model of muscle index change value combined with postoperative pathological type and postoperative pathological staging and the postoperative pathological staging prognostic prediction model in the modeling group and the validation group, respectively ( Z=3.522, 1.830, P<0.05). (5) Evaluation of prognostic prediction models: the nomogram prognostic prediction model of muscle index change value combined with postoperative pathological type and postoperative pathological staging showed that patients with score of 0-6 were classified in the low risk group, patients with score of >6 and ≤10 were classified in the moderate-low risk group, patients with score of >10 and ≤13 were classified in the moderate-high risk group and patients with score of >13 were classified in the high risk group. Kaplan-Meier survival curve showed there were significant differences of the overall survival between the low risk group, moderate-low risk group, moderate-high risk group and high risk group patients in the modeling group and the validation group, respectively ( χ2 =75.276, 14.989, P<0.05). Results of decision making curve showed the nomogram prognostic prediction model of muscle index change value combined with postoperative pathological type and postoperative pathological staging had better clinical utility than the postoperative pathological staging prognostic prediction model in the modeling group and the validation group. Conclusions:The muscle index changing value of gastric cancer patient during neoadjuvant chemotherapy can be used as a prognostic indicator for gastric cancer patient prognosis after radical gastrectomy. The risk score of the nomogram prognostic prediction model of muscle index change value combined with postoperative pathological type and postoperative pathological staging can be used to evaluate the survival and prognosis of gastric cancer patients after radical gastrectomy.

Objective:To investigate the relationship between lexical semantic processing abnormalities and cognitive function and clinical symptoms in schizophrenia based on the activation diffusion model and semantic distance.Methods:All subjects matched with demographic data were randomly divided into experiment group( n=27) and control group( n=30). The semantic distance of words of different semantic categories and lexical categories were assigned at a level of 1-7.The semantic distance between the two groups was analyzed by repeated measures of variance, and the correlation analysis was conducted on the scores of the MATRICS Consensus Cognitive Battery (MCCB) and positive and negative syndrome scale (PANSS) in the experimental group. Results:The main effects of the groups in semantic distance were statistically significant( F(1, 55)=7.460, P=0.008, ηp2=0.981). The semantic distance in the experimental group (3.672±0.105)was lower than that in the control group (4.068±0.100). The main effect of the semantic category was statistically significant( F(1, 55)= 833.37, P<0.01, ηp2=0.938), and the semantic distance in the relative condition (1.965±0.074) was lower than that in the unrelative condition(5.775±0.117). Under the relative condition, concrete semantic deviation was negatively correlated with the total score of MCCB( r=-0.405, P=0.036)and speech learning ( r=-0.569, P=0.002). Abstract semantic deviation was negatively correlated with speech learning( r=-0.429, P=0.026). Under the unrelative condition, concrete semantic deviation was negatively correlated with MCCB total score ( r=-0.597, P=0.001), speech learning( r=-0.399, P=0.039)and other dimensions.Abstract semantic deviation was negatively correlated with MCCB total score( r=-0.593, P=0.001) and speech learning( r=-0.285, P=0.050). Under the relative condition, the abstract semantic deviation was positively correlated with the general symptom scale score( r=0.448, P=0.019). Under the unrelative condition, abstract vocabulary semantic deviation was positively correlated with PANSS total score( r=0.120, P=0.010), negative scale score( r=0.047, P=0.030) and general symptom scale score ( r=0.306, P=0.010). Conclusion:The semantic distance of lexical processing is abnormal in schizophrenia. The semantic deviation is related to the cognitive function index and symptom index.

Objective:To explore the impact of surgical treatment on the life quality of patients with locally advanced hypopharyngeal carcinoma.Methods:A retrospective analysis of the clinical data of 21 patients with advanced hypopharyngeal carcinoma who underwent surgery at the Shenzhen Hospital of Chinese Academy of Medical Sciences Cancer Hospital from January 1, 2017 to December 31, 2019 was conducted. There were 3 patients with recurrence after radiotherapy and chemotherapy, 4 cases of postoperative recurrence, 3 cases of postoperative recurrence after radiotherapy and chemotherapy. Three cases were hypopharyngeal carcinoma with esophageal carcinoma and 8 cases were stage Ⅳ hypopharyngeal carcinoma. Among them, 3 cases were repaired by stomach, 4 cases by free jejunum, 2 case by great saphenous vein for internal carotid artery, 1 case by artificial blood vessel for internal carotid artery, 5 cases by transfer of pectoralis major musculocutaneous flap and 2 cases by transfer of submental island flap. The 21 patients were scored using the European Cancer Research and Treatment Organization′s Quality of Life Head and Neck Tumor Special Scale (EORTC QLQ-H&N35) on the 3 months before and after surgery, and the changes in postoperative life quality were compared.Results:The preoperative life quality score of 21 patients was (56.86±7.95) points and life quality score of 3 months after operation was (50.93±7.91) points. The postoperative life quality was significantly improved ( P<0.05). The improvement of the postoperative life quality of the patients mainly included the improvements of the head and neck pain, swallowing function, diet, taking analgesics and indwelling nasal feeding tubes. The preoperative scores were (7.58±1.56) points, (8.46±1.63) points, (7.94±0.43) points, (1.76±0.12) points and (1.86±0.28) points, respectively, while the scores of 3 months after operation were (5.02±1.23) points, (6.28±1.58) points, (6.34±0.36) points , (1.12±0.08) points and (1.24±0.18) points, the differences were statistically significant (all P<0.05). Conclusion:The flexible selection of flap repair for locally advanced hypopharyngeal carcinoma is still feasible, and surgery can improve the life quality of patients.

The 5-HTreceptor agonist 8-hydroxy-2-[di--propylamino] tetralin (8-OH-DPAT) promotes ejaculation of male rats, whereas dapoxetine delays this process. However, the gene expression profile of the brain at ejaculation following administrationof these two compounds has not been fully elucidated. In the present study, a transcriptomic BodyMap was generated by conducting mRNA-Seq on brain samples of male Sprague-Dawley rats. The study included four groups: pre-copulatory control (CK) group, ejaculation (EJ) group, 0.5 mg/kg 8-OH-DPAT-ejaculation group (DPAT), and 60 mg/kg dapoxetine-ejaculation (DAP) group. The resulting analysis generated an average of approximately 47 million sequence reads. Significant differences in the gene expression profiles of the aforementioned groups were observed in the EJ (257 genes), DPAT (349 genes) and the DAP (207 genes) compared with the control rats. The results indicate that the expression ofandwas significantly different after treatment with 8-OH-DPAT, whereas the expression ofwas significantly different after treatment with dapoxetine. Other genes, such as,and, exhibited significant differences in expression after the two treatments and are related to bladder cancer, renal cell carcinoma and sexual addiction. The present study reveals the basic pattern of gene expression that was activated at ejaculation in the presence of 8-OH-DPAT or dapoxetine, providing preliminary gene expression information during rat ejaculation.

Mogrosides and steroid saponins are tetracyclic triterpenoids found in. Squalene synthase (SQS) and cycloartenol synthase (CAS) are key enzymes in triterpenoid and steroid biosynthesis. In this study, full-length cDNAs ofandwere cloned by a rapid amplification of cDNA-ends with polymerase chain reaction (RACE-PCR) approach. ThecDNA has a 1254 bp open reading frame (ORF) encoding 417 amino acids, and thecDNA contains a 2298 bp ORF encoding 765 amino acids. Bioinformatic analysis showed that the deduced SgSQS protein has two transmembrane regions in the C-terminal. Bothandhave significantly higher levels in fruits than in other tissues, suggesting that steroids and mogrosides are competitors for the same precursors in fruits. Combinedprediction and subcellular localization, experiments in tobacco indicated that SgSQS was probably in the cytoplasm or on the cytoskeleton, and SgCAS was likely located in the nucleus or cytosol. These results will provide a foundation for further study ofandgene functions in, and may facilitate improvements in mogroside content in fruit by regulating gene expression.
