Addressing the enduring challenge of evaluating traditional Chinese medicines (TCMs), the integrated evidence chain-based effectiveness evaluation of TCMs (Eff-iEC) has emerged. This paper explored its capacity through a demonstration study that evaluated the effectiveness evidence of six commonly used anti-hepatic fibrosis Chinese patent medicines (CPMs), including Biejiajian Pill (BP), Dahuang Zhechong Pill (DZP), Biejia Ruangan Compound (BRC), Fuzheng Huayu Capsule (FHC), Anluo Huaxian Pill (AHP), and Heluo Shugan Capsule (HSC), using both Eff-iEC and the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) system. The recognition of these CPMs within the TCM academic community was also assessed through their inclusion in relevant medical documents. Results showed that the evidence of BRC and FHC received higher assessments in both Eff-iEC and GRADE system, while the assessments for others varied. Analysis of community recognition revealed that Eff-iEC more accurately reflects the clinical value of these CPMs, exhibiting superior evaluative capabilities. By breaking through the conventional pattern of TCMs effectiveness evaluation, Eff-iEC offers a novel epistemology that better aligns with the clinical realities and reasoning of TCMs, providing a coherent methodology for clinical decision-making, new drug evaluations, and health policy formulation.

The clinical antiprotozoal drug nitazoxanide has been demonstrated to improve the experimental diabetes mellitus, lipid metabolism disorders, atherosclerosis and inhibit inflammation. Since the pathogenesis of heart failure with preserved ejection (HFpEF) is multifactorial and closely associated with the aforementioned diseases, we aim to study the effect of nitazoxanide on high-fat diet (HFD) plus L-NAME (N ω-nitro-l-arginine methyl ester)-induced HFpEF and metabolic syndrome in mice. We found that oral nitazoxanide improved cardiac hypertrophy, cardiac fibrosis, cardiac diastolic dysfunction, increased blood pressure, impaired exercise tolerance, impaired glucose handling, serum lipid disorders, hepatic steatosis, increased weight of white adipose tissues and kidney fibrosis in HFD + L-NAME-treated mice. In the established HFD + L-NAME-induced HFpEF and metabolic syndrome mouse model, therapeutic treatment with nitazoxanide rescued HFD + L-NAME-induced pathological phenotypes as mentioned above. The in vitro experiments revealed that tizoxanide, the active metabolite of nitazoxanide, increased the basal mitochondria metabolism of cardiomyocytes, inhibited cardiomyocyte hypertrophy and collagen secretion from cardiac fibroblasts, and relaxed phenylephrine- and U46619-induced constriction of rat mesenteric arteries, indicating that the direct effect of tizoxanide might partly contribute to the protective effect of nitazoxanide against HFpEF in vivo. The present study suggests that nitazoxanide might be a potential drug for HFpEF and metabolic syndrome therapy.

ObjectiveBy starting with the combination of Os Draconis， Bupleuri Radix， and Ostreae Concha， the role of mineral medicine Os Draconis in the combination of the Bupleuri Radix-containing tri-herbal medicines was preliminarily explored from the perspective of supramolecular system formation. Method① The appearance and Tyndall phenomenon of single decoction of Os Draconis， Bupleuri Radix， and Ostreae Concha， as well as co-decoction of Bupleuri Radix-Os Draconis， Bupleuri Radix-Os Draconis-Ostreae Concha， and Bupleuri Radix-Ostreae Concha were observed， and the average particle size， dispersion coefficient， and Zeta potential of suspension particles in each decoction were determined. The micromorphology of supramolecular structures was observed by scanning electron microscope （SEM）. ② The pH of different compatibility systems， liquid viscosity coefficient， liquid surface tension， freeze-dried powder yield rate， and other physical properties were determined， and the interaction of different compatibility systems was detected by infrared absorption spectroscopy （FTIR） and UV-visible spectrophotometry （UV-Vis）. ③ The composition and content difference of different compatible systems were determined by high-performance liquid chromatography （HPLC） and ultra-performance liquid chromatography-quadrupole-time of flight mass spectrometry （UPLC-Q-TOF-MS）. ResultCompared with the single decoction， the co-decoction had more obvious turbidity and Tyndall phenomenon. The particles in the co-decoction suspension were smaller and more evenly distributed， and the Zeta potential was reduced， indicating a more stable system. Under SEM， Bupleuri Radix was irregularly lamellar， and Bupleuri Radix-Os Draconis and Bupleuri Radix-Os Draconis-Ostreae Concha were mainly spherical nanoparticles. Bupleuri Radix-Ostreae Concha was irregularly lamellar， with a small number of spherical nanoparticles. The pH of the single decoction of Bupleuri Radix and co-decoction increased， and the viscosity coefficient increased. The liquid surface tension decreased. The freeze-dried powder yield rate of the Bupleuri Radix-Os Draconis co-decoction was the highest， followed by Bupleuri Radix-Ostreae Concha decoction and Bupleuri Radix-Os Draconis-Ostreae Concha decoction， and the yield rate of Bupleuri Radix single decoction was the lowest. The main change of FTIR was the stretching vibration of -OH， and the co-decoction moved to the low-frequency direction obviously. UV-Vis showed that the maximum absorption occurred at 295.8 nm for all groups， and the absorption intensity was different （Bupleuri Radix-Os Draconis>Bupleuri Radix-Os Draconis-Ostreae Concha>Bupleuri Radix-Ostreae Concha>Bupleuri Radix）. The components of Bupleuri Radix were used as the indexes， and the content of methanol extract determined by HPLC was higher than that of water extract， and the components of Bupleuri Radix single decoction were mainly saikosaponin a （SSa） and saikosaponin c （SSc）， which were slightly higher after co-decoction compatibility. UPLC-Q-TOF-MS could identify 37 compounds in both single decoction and co-decoction. ConclusionThe combination of Bupleuri Radix， Os Draconis， and Ostreae Concha can form a smaller， more uniform， and stable nano-sized supramolecular system， which is conducive to the dissolution of the main components of Bupleuri Radix， and the Os Draconis contributes the most in this process.

Objective To observe the changes of plasma gastrointestinal hormones in motion sickness sensitive and insensitive individuals before and after vertical oscillation stimulation,and to construct a susceptibility prediction model for motion sickness.Methods A total of 60 healthy male volunteers were enrolled to receive sinusoidal vertical oscillation stimulation for 45 min.The motion sickness susceptibility questionnaire(MSSQ)was filled out before the experiment.Immediately after motion,the severity of motion sickness was evaluated by Graybiel scale.The motion sickness sensitive(Graybiel score≥8 and MSSQ susceptibility index＞21,n=15)and insensitive(Graybiel score≤2 and MSSQ susceptibility index＜5,n=15)participants were screened.Plasma levels of glucagon-like peptide-1(GLP-1),cholecystokinin(CCK),leptin,ghrelin,neuropeptide Y(NPY)and orexin A(OXA)were detected by enzyme-linked immunosorbent assay before and after vertical oscillation stimulation.Logistic regression model was used to analyze the predictive effect of plasma gastrointestinal hormone levels on susceptibility to motion sickness,and a combined predictive model was established.Receiver operating characteristic(ROC)curve was used to analyze predictive value of the model.Results Ghrelin and CCK levels were significantly increased in the sensitive group after stimulation compared with those before stimulation(both P＜0.01),while NPY and leptin levels were significantly decreased(both P＜0.01).Similar results were also observed when compared with the insensitive group after stimulation.Multivariate logistic regression analysis showed that plasma ghrelin,CCK and NPY were independent predictors of susceptibility to motion sickness.The established susceptibility prediction model for motion sickness was logit(P)=-0.051 ×ghrelin+0.060× NPY-0.169 ×CCK+33.397.ROC curve analysis showed that area under curve(AUC)value of the prediction model was 0.988,the sensitivity and specificity were 100.0％and 93.3％,respectively,and the prediction effect was better than ghrelin,CCK and NPY alone(AUC=0.792,0.880,0.838).Conclusion The changes of peripheral gastrointestinal appetite regulating hormone levels may be related to the susceptibility to motion sickness.The combined use of these indicators can predict the susceptibility to motion sickness.

Objective To explore the improving effects of motion sickness acclimatization training methods,namely sinusoidal vertical oscillation stimulation and sinusoidal vertical oscillation stimulation combined with visual virtual reality(VR)swell stimulation,on cognitive performance of individuals with extremely severe motion sickness.Methods A total of 90 individuals with extremely severe motion sickness screened by the Graybiel score during 6 h navigation were randomly divided into vertical group,vertical+VR group,and control group(n=30).The abilities of vigilance,memory,rapid calculation,information processing and visual manipulation were evaluated before and after the acclimatization training using a self-developed cognitive performance evaluation software.Results On the 1st day of training,the numbers of missed targets of the vertical group and vertical+VR group were increased in the vigilance test;the reaction time was prolonged in the short-term memory,rapid calculation,information processing and visual manipulation tasks;and the efficiency of rapid calculation was reduced.After acclimatization training,the numbers of missed targets were reduced to the baseline level in the vertical and vertical+VR groups,and the reaction time in the short-term memory,rapid calculation,information processing and visual manipulation tasks and the efficiency of rapid calculation were improved.Conclusion Motion sickness caused by vertical oscillation stimulation or vertical oscillation combined with visual VR swell stimulation can decrease vigilance,short-term memory,rapid calculation,information processing and visual manipulation abilities.Motion sickness acclimatization training can significantly improve the above cognitive abilities.

Objective To study the acclimatization time and effects for preventing motion sickness under sinusoidal vertical oscillation stimulation,visual virtual reality(VR)swell stimulation,and their combined stimulation.Methods Totally 120 individuals with extremely severe motion sickness during 6 h navigation were randomly divided into 4 groups(n=30):vertical group,VR group,vertical+VR group,and control group.The severity of symptoms during the training period was assessed daily by Graybiel scale,and the number of drops from flexible treadmill in the VR group was recorded.The Graybiel score of 0 for 3 d and/or the number of drops for 0 were considered as complete acclimatization.The training effect was validated by navigation under more severe sea conditions.Results The Graybiel scores of the vertical group and vertical+VR group,as well as the number of drops of the VR group were decreased with the increase of training days,and reached the acclimatization level on the 3rd,5th,and 2nd training day,respectively.The longest acclimatization time in the vertical,vertical+VR,and VR groups was 8,8,and 5 d,with an average acclimatization time of 3.6,3.9,and 2.7 d,respectively;the acclimatization rates within 5 d were 93.33％(28/30),76.67％(23/30),and 100.00％(30/30),respectively;the proportions of individuals with effective acclimatization training in the verification voyage were 86.67％(26/30),96.67％(29/30),and 66.67％(20/30),respectively;and the training efficiency was 85.19％,96.30％,and 62.97％,respectively.Conclusion Three training methods all have effects on motion sickness acclimatization,and the acclimatization period is 5-8 d.The acclimatization effects of the vertical oscillation and vertical oscillation+VR training are better than the VR training.

Objective To observe the effect of the supine-posture ripple wood training in preventing motion sickness caused by linear acceleration.Methods Totally 61 motion sickness sensitive males were screened by a vertical oscillation simulator and divided into mildly sensitive group(Graybiel score 1-15,n=28)and severely sensitive group(Graybiel score 16,n=33).The participants in the 2 groups received 5-d ripple wood training,30 min/d.The movement frequency of the ripper wood was maintained at 0.25-0.35 Hz,with an acceleration of 0.15-0.25 g.Graybiel score during the training period was recorded.The static balance function test was conducted before and after training on the 1st and 5th day.Results During the training period,the Graybiel scores and motion sickness incidence in the severely sensitive group were decreased with the increase of training days,and all participants achieved complete acclimatization on the 4th day.The Graybiel scores of the mildly sensitive group were low during the whole period,and the complete acclimatization period was 2 d.There was no significant difference in the sway area of the severely sensitive group in static balance function test before and after training(P＞0.05).The mean velocity of the severely sensitive group in static balance function test was significantly increased after training versus before training on the 1st day(P＜0.01),and there was no significant difference before and after training on the 5th day(P＞0.05).There were no significant differences in the sway area or mean velocity of the mildly sensitive group during the whole training period(all P＞0.05).The validation experiment showed that the motion sickness incidence and the symptom severity were significantly decreased in both groups;the motion sickness incidence of the mildly sensitive group decreased from 100.00％(28/28)to 35.71％(10/28);the incidence of severe symptoms in the severely sensitive group decreased from 100.00％(33/33)to 6.06％(2/33)and the vomiting incidence decreased from 96.97％(32/33)to 6.06％(2/33).Conclusion The supine-posture ripple wood training has great effect in preventing motion sickness,with widespread use and simple operation.

Objective:To investigate the clinicopathological characteristics of early-onset colorectal cancer.Methods:The retrospective and descriptive study was conducted. The clincopatholo-gical data of 59 206 patients with colorectal cancer in the Surveillance, Epidemiology, and End Results Program of the United States of America From January 1,2010 to December 31,2019 were collected. There were 33 213 males, 25 993 males, aged (50±7)years. Observation indicators: (1) demographic and oncological characteristics of colorectal cancer patients; (2) comparison of clinico-pathological characteristics between early-onset and late-onset colorectal cancer. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the t test. Measurement data with skewed distribution were represented as M( Q1, Q3), and comparison among groups was conducted using the Kruskal-Wallis H test. Count data were described as absolute numbers, and comparison among groups was conducted using the chi-square test. Comparison of ordinal data was conducted using the non-parameter H test. Patients with early-onset colorectal cancer were segmented by age, and missing data for categorical variables is set as unknown. Results:(1) Demographic and oncological characteristics of colorectal cancer patients. Of 59 206 patients, there were 23 104 cases with early-onset colorectal cancer and 36 102 cases with late-onset colorectal cancer, and cases aged 13-29 years, cases aged 30-34 years, cases aged 35-39 years, cases aged 40-44 years, cases aged 45-49 years, cases aged 55-59 years were 1 041, 1 740, 3 288, 6 050, 10 985, 15 303,20 799, respectively. (2) Comparison of clinicopathological charac-teristics between early-onset and late-onset colorectal cancer. ① There were significant differences in gender, tumor location, degree of tumor differentiation, tumor histological type, tumor TNM staging, tumor T staging, tumor N staging, tumor M staging, preoperative carcinoembryonic antigen (CEA), perineural invasion, cancer nodule, tumor diameter between patients with early-onset and late-onset colorectal cancer ( P<0.01). Results of further analysis showed that cases with tumor located in ileocecal region, ascending colon, colon liver region, transverse colon were 2 329, 2 139, 579, 1 303 in the 6 350 patients with early-onset right colon cancer. The above indicators were 4 563, 3 945, 902, 1 951 in the 11 361 patients with late-onset right colon cancer. There was a significant difference in the above indicators between the two groups of patients ( χ2=114.27, P<0.01). Cases with tumor located in splenic region of the colon, descending colon, sigmoid colon, rectum sigmoid junction were 553, 1 354, 6 404, 2 431 in the 10 742 patients with early-onset left colon cancer. The above indicators were 865, 1 798, 9 668, 3 610 in the 15 941 patients with late-onset left colon cancer. There was a significant difference in the above indicators between the two groups of patients ( χ2=35.60, P<0.01). ②Of 23 104 patients with early-onset colorectal cancer, cases aged 13-29 years, cases aged 30-34 years, cases aged 35-39 years, cases aged 40-44 years, cases aged 45-49 years were 1 041, 1 740, 3 288, 6 050, 10 985, respectively. There were significant differences in gender, degree of tumor differentiation, tumor histological type, tumor TNM staging, tumor T staging, tumor N staging, pre-operative CEA, perineural invasion, cancer nodule, tumor diameter among patients of different age groups ( P<0.01). Results of further analysis showed that cases with tumor located in ileocecal region, ascending colon, colon liver region, and transverse colon were 91, 117, 45, 69 in the 6 350 early-onset right colorectal cancer patients aged 13-29 years. The above indicators were 165, 136, 47, 115, 304, 313, 93,201, 614, 535, 151, 330, 1 155, 1 038, 243, 588 in early-onset right colorectal cancer patients aged 30-34, 35-39, 40-44, 45-49 years, respectively. There was a significant difference in the above indicators among the five groups of patients ( H=36.63, P<0.01). Cases with tumor located in splenic region of the colon, descending colon, sigmoid colon, rectum sigmoid junction were 32, 83, 260, 95 in the 10 742 early-onset left colorectal cancer patients aged 13-29 years. The above indica-tors were 53, 112, 452, 171, 95, 230, 867, 342, 149, 337, 1 702, 665, 224, 592, 3 123, 1 158 in the 10 742 early-onset left colorectal cancer patients aged 30-34, 35-39, 40-44, 45-49 years, respectively. There was a significant difference in the above indicators among the five groups of patients ( H=47.84, P<0.01). Conclusions:Compared with late-onset colorectal cancer, early-onset colorectal cancer are more likely to occur in the left colon and rectum, with poorly differentiated and undifferentiated tumors, histological type of mucinous adenocarcinoma, TNM staging of stage Ⅲ and Ⅳ, higher proportion of nerve infiltration and cancer nodules, and larger tumor diameter. There are significant differences in clinicopathological characteristics of tumors among patients with early-onset colorectal cancer of different age groups.

Objective:To evaluate the safety and tolerance of sequential thoracic radiotherapy combined with PD-1/PD-L1 inhibitors in patients with extensive-stage small cell lung cancer (ES-SCLC) after induction systemic therapy.Methods:ES-SCLC patients from a phase I trial and a real-world study were enrolled for those who received thoracic radiotherapy after induction systemic treatment (chemotherapy/chemotherapy combined with PD-1/PD-L1 inhibitors) and consolidated with PD-1/PD-L1 inhibitors. These two studies were both approved by the Ethics Committee of Chinese Academy of Medical Sciences Cancer Hospital (Clinical Trials.gov number, NCT03971214, NCT04947774).Results:Between January 2019 and March 2021, a total of 11 patients with ES-SCLC were analyzed, aged 52-73 years, with a median age of 62 years. Among them, five patients (45.5%) received induction chemotherapy and six patients (54.5%) received chemotherapy combined with PD-1/PD-L1 inhibitor, and then all received intensity-modulated thoracic radiotherapy after evaluation of systemic treatment efficacy. Two patients developed treatment-related grade G3-5 toxicity (18.2%, 1 treatment-related pneumonitis and 1 radiation esophagitis). G 1-G 2 hematologic toxicity, pneumonia, and anorexia were common mild toxicities. Only one patient (9.1%) terminated immunotherapy due to immune-related pneumonitis. During a median follow-up time of 12.5 months (range: 3.5-16.4 months), the median disease progression-free survival and overall survival was 7.4 months (95% CI: 6.9-8.0 months) and 14.6 months (95% CI: 9.0-20.2 months), respectively. Conclusions:Sequential thoracic radiotherapy followed by PD-1/PD-L1 inhibitor is safe and feasible in patients with ES-SCLC after induction therapy. Given that both thoracic radiotherapy and immunotherapy benefits the ES-SCLC in survival, this comprehensive treatment modality warrants further investigation.
