OBJECTIVE To construct a clinical model of motion sickness(MS),provide a relatively objective diagnostic model for MS research,and provide a basis for further clinical intervention of the disease.METHODS A total of 60 subjects were included and divided into experimental group and control group according to the presence or absence of MS.The MS clinical model was established using SRM-IV rotating chair.Peripheral blood was collected before and after acceleration exposure,and the contents of adrenocorticotropic hormone(ACTH),growth hormone(GH),prolactin(PRL),follicle stimulating hormone(FSH),luteinizing hormone(LH),thyroid stimulating hormone(TRH)and gastrin-17(G-17),acetylcholine(ACH)and 5-hydroxytryptamine(5-HT)were detected,Graybiel scale was used to evaluate the severity of MS.The correlation between MS symptoms and signs and peripheral blood indexes was analyzed by multiple linear regression,and the diagnostic model was established.construct a clinical model of MS and a diagnostic model based on blood parameters,so as to provide a reliable clinical model and an objective diagnostic model for MS research,and to provide a basis for further clinical intervention of the disease.RESULTS After acceleration exposure,the Graybiel scores,ACH,5-HT,ACTH,GH and PRL levels in peripheral blood of the experimental group were higher than those before exposure,and were significantly different from those of the control group(P<0.001).There was no significant difference in FSH,LH,TRH and G-17 between the two groups before and after acceleration exposure(P>0.05).Multi-index combined diagnostic model:Graybiel scores=-9.32+0.131×ACTH+0.055×ACH+0.041×5-HT.CONCLUSION The levels of ACH,5-HT,ACTH,GH and PRL increased during the onset of MS.The multi-index combined diagnosis model can provide a certain basis for the objective diagnosis of MS in clinical practice.

The correlation between hearing loss (HL) and physical performance in patients receiving maintenance hemodialysis (MHD) remains poorly investigated. This study explored the association between HL and physical performance in patients on MHD. Methods: This multicenter cross-sectional study was conducted between July 2020 and April 2021 in seven hemodialysis centers in Shanghai and Suzhou, China. The hearing assessment was performed using pure-tone average (PTA). Physical performance was assessed using the Timed Up and Go Test (TUGT), handgrip strength, and gait speed. Results: Finally, 838 adult patients (male, 516 [61.6%]; 61.2 ± 2.6 years) were enrolled. Among them, 423 (50.5%) had mild to profound HL (male, 48.6% and female, 53.4%). Patients with HL had poorer physical performance than patients without HL (p < 0.001). TUGT was positively correlated with PTA (r = 0.265, p < 0.001), while handgrip strength and gait speed were negatively correlated with PTA (r = –0.356, p < 0.001 and r = –0.342, p < 0.001, respectively). Physical performance in patients aged <60 years showed significant dose-response relationships with HL. After adjusting for confounders, the odds ratios (95% confidence intervals) for HL across the TUGT quartiles (lowest to highest) were 1.00 (reference), 1.15 (0.73–1.81), 1.69 (1.07–2.70), and 2.87 (1.69–4.88) (p for trend = 0.005). Conclusion: Lower prevalence of HL was associated with a faster TUGT and a stronger handgrip strength in patients on MHD.

ObjectiveThis study aimed to understand the epidemiological characteristics of hand-foot-mouth disease （HFMD） in Minhang District， Shanghai from 2009 to 2020， and provide a scientific basis for the prevention and control of HFMD. MethodsThe case information of HFMD was collected from the National Notifiable Infectious Diseases Reporting System of Chinese Center for Disease Control and Prevention. We used descriptive epidemiological methods to analyze the population characteristics， temporal and spatial distribution of HFMD， the pathogen composition of the case and its changing trend. ResultsFrom 2009 to 2020， a total of 66，198 cases of HFMD were reported in Minhang District， Shanghai， including 377 severe cases （severe case rate 0.57%） and 3 deaths （severs case fatality rate 0.80%）. There were more cases of HFMD in boys than in girls （1.5∶1）. HFMD patients aged under 5 years predominated， accounting for 88.91% of all cases. Majority of the cases （91.42%） were in scattered children （55.80%） and children in kindergartens （35.62%）. The incidence showed a cyclical trend， with low incidence years and high incidence years appearing alternately. The peak period was from April to July， and sometimes there were small peaks during October to December. A total of 12 years time-space scanning analysis revealed 3 clusters. The cluster centers were located in Wujing Town， Huacao Town and Xinzhuang Town， respectively. The proportion of EV71 in common cases was generally decreasing， and reduced to zero in 2019. The proportion of CoxA6 had increased year by year， and reached 75.00% in 2020. CoxA6 became the dominant pathogen in recent years. The number of severe cases had decreased year by year since 2010， and the dominant pathogen was EV71 （90.03% on average） in severe cases. ConclusionThe incidence of HFMD in Minhang District of Shanghai has a downward trend from 2014. The dominant pathogen changes from EV71 to CoxA6， and the dominant pathogen in severe cases is EV71. The discovered temporal and spatial clustering pattern is helpful for in-depth understanding of the distribution and epidemic trend of HFMD in Minhang District， and provides a scientific basis for epidemic prevention and control.

Objective To investigate the expression and clinical significance of TM9SF3 in lung adenocarcinoma (LUAD). Methods TCGA and GEPIA databases were used to screen the differentially-expressed TM9SF family molecules and analyze their effects on patient prognosis with LUAD. The expression and localization of TM9SF3 in LUAD patients were verified by a human proteomic mapping database, Western blot assay, and polymerase chain reaction assay. Herein, the GSEA was used for the signal pathway enrichment analysis of TM9SF3-related genes. Meanwhile, the TIMER database and CIBERSORT algorithm were used to analyze the correlation between differentially-expressed TM9SF3 and the degree of immune cell infiltration. Results The expression of TM9SF3 in LUAD was significantly increased and had a significant adverse effect on the prognosis of LUAD patients. In addition, immunoblotting and polymerase chain reaction confirmed that TM9SF3 was highly expressed in LUAD. Meanwhile, the genes related to TM9SF3 expression were mainly enriched in cell signaling pathways regulating immune cell activity. The expression of TM9SF3 was significantly correlated with the expression changes of six immune cells. Conclusion TM9SF3 is differentially expressed in LUAD and may be used as a potential prognostic marker for LUAD patients. TM9SF3 can also change the level of immune cell infiltration in LUAD patients and is expected to be a new potential target for LUAD immunotherapy.

Recently, accumulating evidence suggests that high bilirubin level is involved in the pathophysiology of schizophrenia. High bilirubin level during early childhood may increase the risk of being suffered from schizophrenia after adulthood, and schizophrenia patients with high bilirubin level have aggravated psychiatric symptoms. As compared with other psychiatric patients and general population, schizophrenia patients usually have relatively higher bilirubin level; high bilirubin level is associated with acute psychotic states, positive symptoms, and poor prognosis in patients with schizophrenia. This article reviews the relation between bilirubin and schizophrenia and its potential pathophysiological mechanism in order to provide a new direction for the study of schizophrenia pathogenesis and auxiliary diagnosis.

Objective To analyze the epidemiological characteristics of viral hepatitis in Minhang District, Shanghai from 2010 to 2020, to predict the number of cases in 2021, and to provide a scientific basis for the prevention and control of viral hepatitis. Methods A descriptive epidemiological method was used to analyze the epidemic data of viral hepatitis in Minhang District of Shanghai from 2010 to 2020. The Holt-Winters additive model was used to predict the incidence of viral hepatitis in the future. Results A total of 10 769 cases of viral hepatitis were reported in Minhang District, Shanghai from 2010 to 2020, with an average annual incidence rate of 38.81/100 000. The reported cases were mainly concentrated in the central urban areas with dense population and large flow of people. The reported population was mainly concentrated in the 20-60 years old (78.2%). The ratio of male to female was 1.92:1. Retirees accounted for the largest proportion of all types of hepatitis. The Holt-Winters additive model predicted 958 cases in 2021. Conclusion The overall prevention and control of viral hepatitis in Minhang District have achieved great success, but still face challenges. It is necessary to further strengthen the publicity and intervention to the floating population, especially the young, middle-aged and retired people, and to strengthen the surveillance to reduce the infection rate.

Objective To find small molecules binding specifically to signal transducer and activator of transcription3 (STAT3) based on surface plasmon resonance (SPR) technology and confirm their inhibitory activities to STAT3. Methods The biomolecular interaction analysis T200 system based on SPR technology was used to couple the purified protein STAT3 to CM5 chip under the optimal pH conditions. The compounds with high binding response value were screened out from 50 candidate compounds derived from traditional Chinese medicines and the binding specificity was then confirmed. Biological experiments were performed to confirm the inhibitory effects of the screened compounds on STAT3. The binding pattern of STAT3 and the compound was fitted by molecular docking technique. Results More than 10 candidate molecules exhibited binding activities to STAT3 and kinetics assays revealed that only one candidate molecule, apigenin, showed specific binding. Western-blot analysis exhibited that apigenin inhibited the phosphorylation of STAT3 dose-dependently. Luciferase reporter gene assays demonstrated that apigenin also inhibited IL-6-induced STAT3 transcriptional activity in a dose-dependent manner. Molecular docking results showed that apigenin binds to the SH2 domain of STAT3, and interacts with key residues Glu638, Gln644, Gly656 and Lys658 by hydrogen bonds and with Tyr657 through π-π interactions. Conclusion Apigenin was a direct inhibitor of STAT3.
