Traditional Chinese Medicine (TCM), as a treasure of the Chinese nation, plays a significant role in maintaining public health. In 2019, the Central Committee of the Communist Party of China and the State Council proposed for the first time the establishment of a TCM registration and evaluation evidence system that integrates TCM theory, "personal experience" and clinical trials (referred to as the "Three-in-One" System) to promote the inheritance and innovation of TCM. Subsequently, the National Medical Products Administration issued several guiding principles to advance the improvement and implementation of this system. Owing to the complexity of its implementation, there are still differing understandings within the TCM industry regarding the positioning of the "Three-in-One" Registration and Evaluation Evidence System, as well as the connotation and value orientation of the "personal experience." To address this, Academician WANG Qi, President of the TCM Association, China International Exchange and Promotion Association for Medical and Healthcare and TCM master, led a group of academicians, TCM masters, TCM pharmacology experts and clinical TCM experts to convene a "Seminar on Promoting the Implementation of the ′Three-in-One′ Registration and Evaluation Evidence System for Chinese Medicinals." Through extensive discussions, an expert consensus was formed, clarifying the different roles of the TCM theory, "personal experience" and clinical trials within the system. It was further emphasized that the "personal experience" is the core of this system, and its data should be derived from clinical practice scenarios. In the future, the improvement of this system will require collaborative efforts across multiple fields to promote the high-quality development of the Chinese medicinal industry.

Objective:To compare the mid- to long-term clinical outcomes of arthrolysis versus revision arthroplasty for arthrofibrosis-related stiffness following total knee arthroplasty (TKA).Methods:A retrospective analysis was conducted of the 20 patients (26 knees) with post-TKA arthrofibrosis who had been treated at Department of Orthopedics, The Fourth Medical Center of Chinese PLA General Hospital between January 2004 and January 2020. The patients were divided into 2 groups based on their treatment: an arthrolysis group of 8 cases (10 knees) [1 male (2 knees)and 7 females (8 knees); median age: 44.0 (21.0, 62.0) years] and a revision arthroplasty group of 13 cases (16 knees) [4 males (6 knees)and 9 females (10 knees); median age: 41.5 (30.0, 56.0) years]. The knee range of motion (ROM) and the American Hospital for Special Surgery (HSS) knee score as well as their improvements were compared between preoperation and the last follow-up, as well as between the 2 groups; the satisfaction of the patients at the last follow-up was compared between the 2 groups.Results:No significant differences in the baseline characteristics were observed between the 2 groups, indicating comparability ( P>0.05). The preoperative knee ROM [55.0° (48.8°, 61.3°)] and HSS knee score [54.0 (47.0, 61.8) points] in the arthrolysis group were significantly higher than those in the revision group [27.5° (6.3°, 50.0°), 33.0 (27.3, 47.8) points] ( P<0.05). In the arthrolysis and revision arthroplasty groups, the knee ROMs [90.0° (65.0°, 100.0°), 90.0° (63.5°, 98.8°)] and HSS knee scores [(69.8±19.9) points, (77.6±11.3) points] at the last follow-up were significantly improved compared with those before operation ( P<0.05). In the revision arthroplasty group, the improvement in knee ROM (48.9°±21.7°) was insignificantly larger than that in the arthrolysis group (34.5°±13.2°) ( P>0.05), but the improvement in HSS knee score [39.5 (25.3, 57.0) points] was significantly larger than that in the arthrolysis group [16.0 (10.5, 25.3) points] ( P<0.05). Respectively, 14 and 3 knees in the revision arthroplasty group and the arthrolysis group resulted in patient satisfaction, showing a significant difference between the 2 groups ( P<0.05). Conclusions:Both arthrolysis and revision arthroplasty can significantly improve knee ROM and HSS knee score in post-TKA arthrofibrosis. However, since revision arthroplasty demonstrates superior improvements in HSS knee score and patient satisfaction, it is preferable for patients with lower preoperative knee ROM.

Objective:To explore the effects of Jianpi Mixture on the glucose receptor/glucagon like peptide-1 (GLP-1)/5-hydroxytryptamine (5-HT) signaling pathway and the mechanism of Jianpi Mixture in improving visceral hypersensitivity in diarrhea-predominant irritable bowel syndrome (IBS-D) rats.Methods:Totally 40 healthy male SPF rats were divided into blank group, model group, Jianpi Mixture low- and high-dosage groups according to the random number table method, with 10 rats in each group. Except for the blank group, the rest of the rats were prepared by the "senna gavage combined with restraint stress" method to replicate the IBS-D spleen deficiency model. The aqueous extract of Jianpi Mixture was 2.52 and 7.56 g/kg in the low- and high-dosage groups, and the same volume of normal saline was given to the blank group and the model group, once a day, for 14 days. On the 1st, 7th and 14th days of administration, the body weight of rats was recorded, the fecal traits of the rats were scored with Bristol score, the visceral sensitivity of IBS-D rats was evaluated by the abdominal wall retraction reflex score (AWR) under rectal dilation, the morphology of colonic mucosal tissues was observed by HE staining, and the protein expressions of T1R2, SLGT1, GLUT2, GLP-1 and 5-HT in colon tissues were detected by immunohistochemical staining.Results:On the 1st, 7th and 14th days of administration, compared with the model group, the weight of the rats in the Jianpi Mixture high-dosage group increased ( P<0.05); on the 14th day of administration, the fecal Bristol score decreased significantly ( P<0.05) and the AWR score increased ( P<0.05); HE staining showed that the mucosal epithelium of colon tissue in the model group was slightly damaged, and local edema was visible. The pathological condition of colonic mucosa in the Jianpi Mixture low- and high-dosage groups was effectively improved; compared with the model group, the expressions of T1R2 and GLP-1 in the Jianpi Mixture low- and high-dosage groups increased ( P<0.05), and the expression of 5-HT decreased ( P<0.05); the protein expressions of GLUT2 and SGLT1 in the Jianpi Mixture high-dosage group increased ( P<0.05). Conclusion:Jianpi Mixture can treat spleen-deficiency IBS-D by restoring the normal expression of intestinal glucose receptors, regulating the secretion of GLP-1/5-HT, improving intestinal motility and alleviating visceral hypersensitivity.

Objective To compare the interaction efficiency of three human-machine interaction modes with hand-touch control,eye movement control and voice control,based on a multi-channel human-machine interaction system in flight mission scenarios.Methods 20 pilots took part in the study and completed the first level(relatively simple)and second level(relatively complex)interactive experimental tasks in three human-computer interaction modes based on specific flight mission scenarios.The interaction efficiency indicators included the system's interaction time,response time,fusion calculation time,and number of errors.After the experiment was completed,the pilots conducted a subjective evaluation,which included the suitability of the interaction mode to the task,consistency with expected usage,fault-tolerance,effective feedback,and the tendency of the interaction mode to be applied in future flight fields.Results There were generally significant differences in interaction efficiency between hand-touch control,voice control,and eye movement control in flight mission scenarios,but the differences differed in first-level and second-level interaction tasks.Based on the comprehensive interaction experimental tasks at all levels,the experimental results obtained included:(1)the interaction time of hand-touch control was the shortest,the interaction time of voice control was the longest,and the main effect of the interaction mode was significant(F=18.214,P<0.001,η2=0.565);(2)The response time of hand-touch control was the shortest,while the response time of eye movement control was the longest.The main effect of interaction mode was significant(F=153.085,P<0.001,η2=0.944);(3)The fusion calculation time for hand-touch control was the shortest,while the fusion calculation time for voice control was the longest.The main effect of the interaction mode was significant(F=41.702,P<0.001,η2=0.777);(4)The errors in voice control were the least,while those in eye movement control were the most.The main effect of interaction mode was significant(χ2=22.845,P<0.001,φ=1.097);(5)The subjective evaluation scores of pilots on voice control were higher than those on eye movement control,and all had statistical significance(P<0.001,P<0.01).Conclusions This study focuses on flight interaction tasks and compares the interaction efficiency of three interaction modes of hand-touch control,voice control,and eye movement control,through a combination of experiments and subjective evaluations.The differences in various interaction efficiency indicators among different interaction modes are found,and the interaction modes have a significant impact on interaction efficiency.Hand-touch control has a significant advantage in interaction time efficiency,voice control has an advantage in accuracy for simple tasks,while eye movement control has relatively weak time efficiency and accuracy;Compared to eye movement control,pilots exhibit higher evaluations and tendencies towards voice control.The research results can provide reference for the future design,evaluation,and application of multi-modal interaction systems.

Objective:To investigate whether stress hyperglycemia (SH) is an independent risk factor for the occurrence and mortality of sepsis-associated encephalopathy (SAE).Methods:From August 2016 to October 2021, sepsis patients admitted to the ICU of Guangdong Provincial People's Hospital were selected as the study subjects. According to whether they developed to SH (RBG>11.1 mmol/L) within 7 days of enrollment, the pat ients were divided into the SH group and the non-SH group for analysis. Logistic regression was used to analyze whether SH was an independent risk factor for SAE occurrence, and ROC curve was used to analyze the predictive value of SH to SAE. Kaplan-Meier curve was used to compare the 90-day survival of SAE patients with or without SH. Cox regression analysis was used to analyze the risk factors of 28-day and 90-day death in SAE patients.Results:A total of 183 sepsis patients were included, including 62 patients in the SH group and 121 in the non-SH group. Logistic regression analysis demonstrated that SH was an independent risk factor for SAE ( OR=4.452, 95% CI: 2.021-9.808, P <0.001). ROC curve demonstrated that SH could accurately predict SAE (AUC=0.831; Sensitivity=78.4%; Specificity=76.8%; and Yoden index=0.553). Kaplan-Meier curve demonstrated that the 90-day survival of SAE patients with SH significantly declined (log-rank test: P<0.01). Cox regression analysis suggested that SH was a risk factor for death at day 28 and day 90 in SAE patients (28 d, HR=2.272, 95% CI: 1.212-4.260, P=0.010; 90 d, HR=2.456, 95% CI: 1.400-4.306, P<0.01). Conclusions:SH is an independent risk factor for SAE and can predict SAE occurrence. SH significantly reduces 90-day survival and increase mortality at 28 and 90 days in SAE patients.

The amygdala is an important hub for regulating emotions and is involved in the pathophysiology of many mental diseases, such as depression and anxiety. Meanwhile, the endocannabinoid system plays a crucial role in regulating emotions and mainly functions through the cannabinoid type-1 receptor (CB₁R), which is strongly expressed in the amygdala of non-human primates (NHPs). However, it remains largely unknown how the CB₁Rs in the amygdala of NHPs regulate mental diseases. Here, we investigated the role of CB₁R by knocking down the cannabinoid receptor 1 (CNR1) gene encoding CB₁R in the amygdala of adult marmosets through regional delivery of AAV-SaCas9-gRNA. We found that CB₁R knockdown in the amygdala induced anxiety-like behaviors, including disrupted night sleep, agitated psychomotor activity in new environments, and reduced social desire. Moreover, marmosets with CB₁R-knockdown had up-regulated plasma cortisol levels. These results indicate that the knockdown of CB₁Rs in the amygdala induces anxiety-like behaviors in marmosets, and this may be the mechanism underlying the regulation of anxiety by CB₁Rs in the amygdala of NHPs.

Objective To observe the difference in the expression of micro-ribonucleic acid(miRNA)in the colon tissue of irritable bowel syndrome-diarrhea(IBS-D)rats and rats treated with Jianpi Mixture,and predict The miRNA and corresponding genes involved in the treatment of IBS-D with Jianpi Mixture,providing a basis for finding potential therapeutic targets for IBS-D.Methods The rats were randomly divided into a blank group,a model group and a traditional Chinese medicine group,with 8 rats in each group.Both the model group and the Chinese medicine group used acute and chronic stimulation + senna leaf gavage to make the IBS-D model.The Chinese medicine group was gavaged with Jianpi Mixture after model building for 14 days.General condition,body weight and Bristol score were observed and recorded.Hematoxylin-eosin(HE)staining was used to observe the histopathological changes of colon in each group of rats.Transcriptome sequencing of rat colon tissue in each group to screen and map differentially expressed miRNAs.Perform GO(Gene oncology)functional enrichment analysis and KEGG(Kyoto Encyclopedia of Genes and Genomes)pathway enrichment analysis on the target genes corresponding to the screened common miRNAs.Results Compared with the model group,the weight of the rats in the Chinese medicine group increased significantly(P<0.01),and the Bristol score of the feces decreased significantly(P<0.01).The pathological damage of the colon tissue of rats in the Chinese medicine group was significantly reduced.Compared with the blank group,there were 109 differentially expressed genes in the model group,of which 80 were up-regulated and 29 were down-regulated.Compared with the model group,there were 109 differentially expressed genes in the traditional Chinese medicine group,of which 19 were up-regulated and 90 were down-regulated.Mapping the genes of the two comparisons found that 74 miRNAs in the model group were increased and 7 were decreased.The changes of these miRNAs were all reversed after the intervention of traditional Chinese medicine.The GO function enrichment analysis of target genes showed that Jianpi Mixture was mainly involved in synaptic vesicle positioning and transport,cytoplasmic transport,negative regulation of growth and development,and sugar transport after acting on rats.KEGG pathway enrichment analysis showed that MAPK,Wnt,Hippo,TNF,oxygen toxin,cAMP and other pathways were enriched.Conclusion After the intervention of Jianpi Mixture,IBS-D-related miRNA expression profiles have changed significantly;Jianpi Mixture may play a protective role in the treatment of IBS-D by regulating the MAPK signaling pathway and Wnt signaling pathway.Screening the core genes and predicting the miRNAs interacting with them provide a theoretical basis for the study of the pathogenesis of IBS-D and the therapeutic targets of Jianpi Mixture.

Objective:To investigate the application value of transverse perineal arc incision approach in complete resection of presacral cyst in the lithotomy position.Methods:The retrospec-tive cohort study was conducted. The clinicopathological data of 114 patients who underwent com-plete resection of presacral cyst in Henan Cancer Hospital from August 2012 to October 2021 were collected. There were 14 males and 100 females, aged (35±9)years. All patients were diagnosed as presacral cysts by preoperative magnetic resonance imaging. Of the 114 patients, 76 patients undergoing intraoperative perineal arc incision approach in the lithotomy position were divided into the innovative group, and 38 patients undergoing intraoperative Kraske approach were divided into the traditional group. Observation indicators: (1) surgical situations and specimen; (2) postoperative situations; (3) Follow-up. 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(range), and comparison between groups was conducted using the Mann-Whitney U test. Count data were described as absolute numbers or percentages, and com-parison between groups was conducted using the chi-square test or Fisher exact probability. Results:(1) Surgical situations and specimen. The operation time, volume of intraoperative blood loss, cases with intraoperative combined transabdominal approach or sacrectomy were (137±20)minutes, (261±101)mL, 0 in the innovation group, versus (136±34)minutes, (261±116)mL, 15 in the tradi-tional group, showing no significant difference in the operation time and volume of intraoperative blood loss between the two groups ( t=0.18, 0, P>0.05) and showing a significant difference in cases with intraoperative combined transabdominal approach or sacrectomy between the two groups ( P<0.05). Results of postoperative specimen anatomy in patients of the two groups showed complete removal of the cyst. (2) Postoperative situations. The time to postoperative removing presacral drainage tube, duration of postoperative hospital stay, cases with postoperative second stage healing of incision were (11.4±2.1)days, (13.5±3.5)days, 23 in the innovation group, versus (11.5±1.9)days, (13.7±3.8)days, 4 in the traditional group, showing no significant difference in the time to post-operative removing presacral drainage tube and duration of postoperative hospital stay between the two groups ( t=-0.20, -0.24, P>0.05) and showing a significant difference in cases with postoperative second stage healing of incision between the two groups ( χ2=5.46, P<0.05). Cases with postoperative severe complications were 4 and 2 in the innovation group and the traditional group, respectively, showing no significant difference between the two groups ( P>0.05). (3) Follow-up. All 114 patients were followed up for 48(range, 6?108)months. Cases with recurrence of cysts were 2 and 0 in the innovation group and the traditional group, respectively, showing no significant difference between the two groups ( P>0.05). During the follow-up period, the anal defecation control function of all patients was classified as grade A?B of Williams score. Conclusions:The transverse perineal arc incision approach in complete resection of presacral cyst in the lithotomy position is safe and feasible. Compared with Kraske approach, the transverse perineal arc incision approach in the lithotomy position is more suitable for patients with high presacral cyst.

Objective:To explore the threshold and diagnostic value of Chinese version of the Chelsea Physical Function Assessment Tool (CPAx-Chi) for ICU acquired weakness(ICU-AW).Methods:To learn the details and precautions of the CPAx-Chi scale, and then two researchers used the CPAx-Chi scale and MRC-Score scale to independently evaluate 200 patients who come from a comprehensive ICU in a top first-class hospital in Gansu Province simultaneously. The best cut-off point and value of the CPAx-Chi scale in the diagnosis of ICU-AW were determined by calculating the Receiver Operating Characteristic (ROC) curve, the Youden index(YI) and the consistency test that are all based on the MRC-Score≤48.Results:The ROC Area Under Curve(AUC) of the CPAx-Chi scale diagnosis ICU-AW which based on the MRC-Score≤48 were as follows: ROC AUC of group A was 0.899 (95% CI 0.862-1.025); ROC AUC of group B was 0.874 (95% CI 0.824-0.925). When the best cut-off point of CPAx-Chi scale for diagnosis ICU-AW was 31.5, the maximum YI=0.643, the sensitivity was 87%, and the specificity was 77% in group A; and the maximum YI= 0.62, the sensitivity was 75%, and the specificity was 87% in group B. Meanwhile, when the best cut-off point of CPAx-Chi scale for diagnosis ICU-AW was 30.5, the maximum YI=0.62, the sensitivity was 79%, and the specificity was 83% in group B. Taking the CPAx -Chi≤31 as the best cut-off point, the score differences in ICU-AW group and the non-ICU-AW group were not detected, A group ( F value was 4.53, P=0.035) or B group ( F value was 6.51, P=0.011). The consistency of CPAx -Chi≤31 and MRC-Score≤48 in the diagnosis of ICU-AW was high, and the Kappa=0.845 ( P=0.02) in the group A; the Kappa=0.839( P=0.04) in the group B, and the group differences were detected. Conclusions:CPAx-Chi≤31 is the best cut-off point for diagnosing ICU-AW, and has good sensitivity and specificity. CPAx-Chi scale can be popularized and applied in the critical care medicine in China.
