Objective Accurate speed perception is crucial for tasks such as man-controlled rendezvous and docking,and teleoperation of space manipulator.Therefore,it is necessary to conduct in-orbit experiments to explore the influence of long-term spaceflight on human speed perception characteristics.Methods The Time-to-Collision(TTC)paradigm was selected to develop experimental software,using a tablet computer for stimulus presentation.Human speed perception characteristics were evaluated based on the subjects'keystroke response data on the keyboard.Through ground-based experiments,the usability and reliability of the paradigm were explored,and the gravity internal model effect was quantitatively analyzed.Through in-orbit experiments on space station tasks,the influence of long-term spaceflight on human speed perception characteristics was further investigated.Results Under the 1G environment on the ground,the TTC paradigm has a high test-retest reliability(r>0.8),and indicators such as average deviation rate and absolute value of average deviation rate show no practice effect.In addition,ground experiments found that compared to vertical upward movement,vertical downward movement is estimated to be faster(i.e.,keystroke time is advanced),showing the existence of the gravity internal model effect.In the microgravity environment of spaceflight,there are no significant differences in average deviation rate and absolute value of average deviation rate among three stages(pre-flight,in-flight,post-flight)and seven tests,indicating that no obvious changes in astronauts'speed perception ability were found at the existing test time points and paradigms.However,the gravity internal model effect(difference between vertical downward and vertical upward)showed a trend of fading in the early stage of astronauts entering orbit.Conclusion Based on the computer screen TTC estimation paradigm,no significant changes in human speed perception ability were found during long-term spaceflight,but microgravity may weaken the human brain's gravity internal model.

Objective To evaluate the effectiveness and safety of Su Fei He Ji combined with anlotinib hydrochloride in the treatment of refractory advanced non-small cell lung cancer(NSCLC)patients presenting with phlegm stasis obstructing lung type.Methods Thirty-nine patients with advanced NSCLC were randomly assigned to either a control group(19 patients)or an experimental group(20 patients).The control group received treatment with anlotinib alone,while the experimental group received an additional oral administration of Su Fei He Ji.A comparative analysis was conducted between the two groups based on various parameters including short-term objective therapeutic efficacy,progression-free survival,TCM syndrome scores,KPS scores,weight changes,related tumor markers,incidence of adverse reactions,and variations in plasma concentrations of anlotinib.Results Following treatment,the objective response rate was 5%and the disease control rate was 85%in the experimental group,while the control group showed an objective response rate of 0%and a disease control rate of 78.95%.No statistically significant difference was observed in short-term objective efficacy between the two groups(P>0.05).Notably,the experimental group exhibited a significant improvement compared to the control group in various aspects,including TCM syndrome scores and KPS scores(P<0.05).Conversely,no significant differences were observed in weight changes or the reduction levels of other tumor markers(CEA,SCC,CA125,CA199,CYFRA21-1)(P>0.05).Moreover,the incidence of fatigue was notably lower in the experimental group(P<0.05),while no statistical difference was evident in the occurrence of other adverse reactions,such as hypertension,rash,and bleeding,between the two groups(P>0.05).It is important to highlight that there was no statistically significant variance in plasma concentrations between the groups(P>0.05),and no significant correlation was identified between plasma concentrations and the incidence of adverse reactions(P>0.05).Conclusion The combination of Su Fei He Ji and anlotinib hydrochloride effectively improves clinical symptoms and quality of life,and reduces adverse reactions in advanced NSCLC patients.This is achieved without affecting the plasma concentrations of anlotinib.

Objective:This multicenter retrospective study aimed to analyze the clinicopathological features of duodenal adenocarcinoma (DA) and identify prognostic factors for postoperative survival.Methods:Demographic characteristics, clinicopathological features, treatment outcomes and survival of DA patients undergoing surgical treatment at 18 Chinese medical centers from January 2012 to December 2023 were retrospectively analyzed.Results:Among the 2 056 DA patients included, 46.8% (963) had extra-ampullary DA (EA-DA), and 53.2% (1 093) had peri-ampullary DA (PA-DA). The 1-, 3-, and 5-year overall survival (OS) rates for patients who underwent radical surgery were 93.2%, 71.0%, and 57.2%, respectively. The median overall survival was 76 months, and the median progression-free survival (PFS) was 65 months. No differences in survival were observed between the laparotomy group and minimally invasive surgery (MIS) group either before or after propensity score matching (OS: 76 vs. 75 months before PSM, P=0.986; OS: 75 vs. 75 months after PSM, P=0.602). Furthermore, there were no significant differences between-group in operation time and postoperative complications ( P＞0.05). The MIS group experienced less intraoperative blood loss and shorter hospital stays. The multivariate Cox regression analysis revealed that advanced age ( HR=1.43,95% CI:1.18-1.73), elevated carbohydrate antigen 19-9 levels ( HR=1.24,95% CI:1.02-1.51), perineural invasion ( HR=1.44,95% CI:1.14-1.81), vascular invasion ( HR=1.35,95% CI:1.07-1.71), advanced T stage (T3-4 vs. T1-2: HR=1.86,95% CI:1.49-2.31), regional lymph node metastasis ( HR=1.93,95% CI:1.58-2.36), preoperative biliary drainage ( HR=1.26,95% CI:1.04-1.53), intraoperative blood loss ( HR=1.34,95% CI:1.11-1.62), clinically significant postoperative pancreatic fistulas ( HR=1.53,95% CI:1.12-2.09), and postoperative hemorrhage ( HR=1.62,95% CI:1.14-2.29) were independent risk factors for poor prognosis after surgery (all P＜0.05). Conclusions:Radical surgery is associated with favorable overall survival among DA patients, and no difference in survival is observed between EA-DA and PA-DA patients. MIS is a reliable alternative for DA treatment.

ObjectiveTo investigate the effects of thyme herbal tea （BLX） on the proliferation of human coronavirus OC43 （HCoV-OC43） in vitro and in vivo. MethodThe chemical composition of BLX was analyzed by UPLC-MS. The cytotoxicity of BLX in HRT-18 cells and the effect of BLX treatment on the proliferation of HCoV-OC43 in cells were analyzed. Copies of viral gene were detected by real-time PCR. The effect of BLX treatment on the life cycle of HCoV-OC43 was detected by time-of-addition assay. The maximum tolerated dose of BLX and the influences of BLX on the body weight and survival time of suckling mice infected with HCoV-OC43 were determined. The expression of viral protein in the brain and lung tissue was analyzed by immunohistochemistry. ResultThere were 11 chemical components identified in BLX by UPLC-MS. BLX showed the 50% cytotoxic concentration （CC₅₀） of （13 859.56±319） mg·L^-1， the median inhibitory concentration （IC₅₀） of （1 439.09±200） mg·L^-1， and the selection index of 8.26-11.44 for HCoV-OC43 in HRT-18 cells. Compared with the cells infected with HCoV-OC43， BLX at the concentrations of 1 500， 1 000， 500 mg·L^-1 inhibited the proliferation of this virus （P<0.05， P<0.01）. BLX exhibited antiviral effect in the early stage of virus infection， and the inhibition role in the attachment stage was more significant than that in the entry stage （P<0.05）. In the suckling mice infected with HCoV-OC43， BLX at 1200 and 600 mg·kg^-1·d^-1 alleviated the symptoms， prolonged the survival period， reduced the death rate， and down-regulated the mRNA level of nucleocapsid protein in the mice. Moreover， BLX at 1 200 mg·kg^-1·d^-1 down-regulated the expression of nucleocapsid protein in the brain （P<0.01） and the lung （P<0.01）. ConclusionBLX contained multiple antiviral ingredients. It inhibited the proliferation of HCoV-OC43 both in vitro and in vivo by interference with viral attachment. This study provides theoretical reference for the treatment of acute respiratory tract infection with HCoV-OC43 and for further development and application of BLX.

OBJECTIVE To establish a clinical pharmaceutical pathway of anti-infective therapy for high-risk populations of antibiotic-associated encephalopathy （AAE）， and analyze its application effects. METHODS Clinical pharmacists developed the “AAE High-Risk Population Screening Form” and “Antibiotic AAE Risk Comparison Form” based on literature and expert opinions， and established the “Clinical Pharmaceutical Pathway of Anti-infective Treatment for AAE High-Risk Population” in our hospital. A prospective， non-randomized controlled study was conducted from May 2023 to April 2024， including 50 cases in the observation group and 50 cases in the control group among patients with pulmonary infections admitted to the Dept. of Internal Medicine in our hospital. The observation group was involved in the development of an anti-infective treatment following the clinical pharmaceutical pathway by clinical pharmacists， while the control group received routine anti-infective treatment by clinical physicians. The occurrence of AAE， the rational antibiotic drug use， and the effectiveness of initial anti-infective treatment in the two groups were observed， and the intervention measures and outcomes of AAE cases were summarized. RESULTS The anti-infective treatment clinical pharmaceutical pathway for AAE high-risk population was preliminarily established in our hospital. The analysis of the application effects showed that there was 1 case of AAE in the observation group and 8 cases in the control group， with a significantly lower incidence of AAE in the observation group than in the control group； the rational antibiotic drug use and the effectiveness of initial anti-infective treatment in the observation group were both significantly superior to those in the control group （P＜0.05）. Drug withdrawal and dressing change were the preferred effective intervention measures for AAE， and encephalopathy treatment drugs could be used as auxiliary measures for symptom relief. Timely and effective intervention was conducive to rapid symptom relief， with a total improvement rate of AAE of 88.89%. CONCLUSIONS The anti-infective treatment clinical pharmaceutical pathway for AAE high-risk population can effectively prevent the occurrence of AAE as well as contribute to promoting rational drug use and the effectiveness of initial anti-infection plans and strengthening treatment outcomes.

Objective To investigate the levels and prognostic value of serum fragment crystallizable gam-ma binding protein(FCGBP)and integrin β4(ITGB4)in elderly patients with severe Mycoplasma pneumoni-ae pneumonia(SMPP).Methods A total of 87 elderly patients with SMPP admitted to Department of Inten-sive Care Medicine in the hospital from January 2020 to December 2023 were selected as the SMPP group,87 elderly patients with general Mycoplasma pneumoniae pneumonia(GMPP)were selected as the GMPP group,and another 87 healthy elderly individuals who underwent physical examinations during the same period were selected as the control group.According to the prognosis after 28 days of treatment,elderly patients with SMPP were divided into a poor prognosis group(31 cases)and a good prognosis group(56 cases).Enzyme linked immunosorbent assay was used to detect serum FCGBP and ITGB4 levels.A multivariate unconditional Logistic regression model was established to determine the factors affecting the poor prognosis of elderly pa-tients with SMPP,and receiver operating characteristic curve was drawn to evaluate the predictive value of se-rum FCGBP and ITGB4 levels for the poor prognosis.Results The serum FCGBP levels in the control group,GMPP group,and SMPP group increased sequentially,while the ITGB4 levels decreased sequentially(P＜0.05).The incidence of poor prognosis in 87 elderly patients with SMPP was 35.63％(31/87).Compared with the good prognosis group,the poor prognosis group showed an increase in serum FCGBP levels and a de-crease in ITGB4 levels(P＜0.05).Age increase(OR=1.200,95％CI:1.036-1.391),high CURB-65 score(OR=2.303,95％CI:1.204-4.403),and high FCGBP level(OR=1.057,95％CI:1.011-1.105)were the independent risk factors for poor prognosis of elderly patients with SMPP(P＜0.05).High oxygenation index(OR=0.980,95％CI:0.963-0.997)and high ITGB4 level(OR=0.961,95％CI:0.929-0.994)were inde-pendent protective factors(P＜0.05).The area under the curve of serum FCGBP combined with ITGB4 level for predicting the poor prognosis was 0.886(95％CI:0.800-0.944),which was larger than 0.789(95％CI:0.689-0.869)and 0.781(95％CI:0.680-0.863)predicted by serum FCGBP and ITGB4 alone(P＜0.05).Conclusion Elevated serum FCGBP levels and decreased ITGB4 levels in elderly patients with SMPP are in-dependently associated with poor prognosis.The combination of serum FCGBP and ITGB4 levels has a high predictive value for poor prognosis in elderly patients with SMPP.
