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 explore the risk factors of ultrasound-guided closed reduction failure of unstable lateral humeral condylar fractures in children.Methods:A retrospective case-control study was conducted to analyze the clinical data of 158 children with unstable lateral humeral condyle fractures admitted to Anhui Provincial Children′s Hospital from January 2022 to August 2023, including 102 males and 56 females, aged 1-14 years [5(4, 8)years]. The patients were divided into reduction success group ( n=136) and reduction failure group ( n=22) according to the results of ultrasound-guided closed reduction. The gender, age, body mass index, injury side, time from injury to surgery, direction of sagittal plane displacement of the fracture fragment, Milch classification, Song classification, concomitant subcutaneous bruising or not, nighttime surgery or not, surgeons′ lack of experience or not, and concomitant elbow dislocation or not were recorded in both groups. Univariate analysis and binary Logistic regression analysis were used to evaluate and identify the independent risk factors for ultrasound-guided closed reduction failure of unstable lateral humeral condylar fractures in children. Results:Univariate analysis showed that there were significant differences in the time from injury to surgery, direction of sagittal plane displacement of the fracture fragment, and surgeons′ lack of experience or not between the reduction success group and reduction failure group ( P<0.01), while there were no significant differences in gender, age, body mass index, injury side, Milch classification, Song classification, concomitant subcutaneous bruising or not, nighttime surgery or not, or concomitant elbow dislocation or not between the two groups ( P>0.05). Binary Logistic regression analysis showed that the time from injury to surgery≥5 days ( OR=1.47, 95% CI 1.17, 1.86, P<0.01), sagittal anterior displacement of the fracture fragment ( OR=7.07, 95% CI, 1.79, 27.98, P<0.01) and surgeons′ lack of experience ( OR=4.67, 95% CI, 1.21, 18.05, P<0.05) were significantly correlated with ultrasound-guided closed reduction failure of unstable lateral humeral condylar fractures in children. Conclusion:The time from injury to surgery ≥5 days, sagittal anterior displacement of the fracture fragment and surgeons′ lack of experience are the independent risk factors for ultrasound-guided closed reduction failure of unstable lateral humeral condylar fractures in children.

The findings could provide valuable insights for improvements in the pharmaceutical sector and future policy adjustments.

OBJECTIVE To evaluate the cost-effectiveness of regorafenib in the treatment of hepatocellular carcinoma after failure of sorafenib from the perspective of Chinese health system. METHODS Based on a phase Ⅲ trial（RESORCE）， the partition survival model （PSM） and Markov model were constructed. The cycle was set as four weeks， the duration of the study lasted for lifetime， the annual discount rate was 5%. Drug cost data was obtained from yaozhi.com， other cost data were obtained from Anhui Provincial Medical Insurance Bureau and related literature， and utility values were obtained from literature. The incremental cost-effectiveness ratio （ICER） was used as the evaluation index， and the value of willingness to pay （WTP） was three times of China’s gross domestic product （GDP） per capita in 2022； one-way sensitivity analysis and probabilistic sensitivity analysis were used to verify the robustness of the basic analysis results. RESULTS The incremental cost of regorafenib group versus placebo group in PSM and Markov model was 112 116.95 yuan and 96 617.19 yuan， respectively. The incremental effectiveness was 0.31 QALYs and 0.32 QALYs， respectively. The ICERs were 360 751.01 yuan/QALY and 301 114.45 yuan/QALY， which were both greater than the value of WTP； regorafenib was not cost-effective. Results of one-way sensitivity analysis showed that the utility of progression-free survival and progressive disease， the unit cost of regorafenib had the greatest influence on the results， but ICER was always greater than the WTP within the floating range of each parameter. Under the WTP of 3 times China’s per capita GDP in 2022， the probabilities of regorafenib with cost-effectiveness were 0.8% （PSM） and 11.4% （Markov）. CONCLUSIONS Under the WTP of 3 times the per capita GDP of China， regorafenib is not cost-effective in the treatment of hepatocellular carcinoma after failure of sorafenib treatment， compared with placebo.

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 investigate the natural evolution of the sciatic bone thickness in pediatric untreated unilateml developmental dysplasia of the hip ( DDH)aged 1-15 years. Methods: 329 cases of DDH childrn aged 1-15 years with unilateral disloeation were retrospectively reconled. The connection lines were defined on the coronal plane or axial plane of CT. The connection lines of the Y ⁃shaped cartilage center on both sides were line H , the connection lines of the lowest edge of the ischia on both sides were line b , and the middle part of the two lines were divided into Zone 1 and Zone 2. Zone 1 represented the marginal area , and Zone 2 represented the central area. The thickness of ischium , epiphyseal plate , iliac bone thickness and epiphyseal quotient of femoral head on both sides were measured and compared. Results : In coronal CL1 ⁃CL4 , the ischial thickness gradually increased with age from 1 to 10 years old , and decreased from 11 to 15 years old. The range of ischial thickness of CL1 ⁃CL4 was 2. 1 - 16. 7 mm , 3. 3 - 18. 9 mm , 2. 4 - 13. 6 mm and 3. 0 - 14. 9 mm , respectively. The width of the epiphyseal plate in coronal position , the width of the epiphyseal plate in axial position , and the thickness of the iliac bone in the affected side were greater than those in the opposite side and had statistical differences. In the correlation test of ischial thickness with age and degree of dislocation , the thickness of ischial bone in coronal and axial positions was moderately correlated with age ( r = 0. 413 - 0. 570 , P < 0. 05) , and had no correlation with the degree of dislocation ( r = 0. 024 - 0. 073 , P > 0. 05) . In the correlation tests of ischial thickness and epiphyseal thickness CD , epiphyseal quotient , coronal iliac thickness IL on the affected side , the thickness of ischial bone in different parts and sections were positive ( r = 0. 427 - 0. 681 , P < 0. 05) , and the thickness of ischial bone was negatively correlated with the epiphyseal quotient ( r = 0. 130 - 0. 241 , P < 0. 05) . Conclusion The ischial thickness in coronal zone 1 and zone 2 of 1 - 10 years old children with unilateral DDH increased at a stable rate with age , and the growth rate decreased gradually in 11 - 15 years old. The thickness of ischia on the affected side in different sections and areas were greater than that on the opposite side. The difference in the central area of the hip joint was greater than that in the marginal area. The thickness of ischia was positively correlated with acetabular cartilage index , epiphyseal plate thickness , and coronal iliac bone thickness.

Metabolic-associated fatty liver disease (MAFLD), which is previously known as non-alcoholic fatty liver disease (NAFLD), represents a major health concern worldwide with limited therapy. Here, we provide evidence that ferroptosis, a novel form of regulated cell death characterized by iron-driven lipid peroxidation, was comprehensively activated in liver tissues from MAFLD patients. The canonical-GPX4 (cGPX4), which is the most important negative controller of ferroptosis, is downregulated at protein but not mRNA level. Interestingly, a non-canonical GPX4 transcript-variant is induced (inducible-GPX4, iGPX4) in MAFLD condition. The high fat-fructose/sucrose diet (HFFD) and methionine/choline-deficient diet (MCD)-induced MAFLD pathologies, including hepatocellular ballooning, steatohepatitis and fibrosis, were attenuated and aggravated, respectively, in cGPX4-and iGPX4-knockin mice. cGPX4 and iGPX4 isoforms also displayed opposing effects on oxidative stress and ferroptosis in hepatocytes. Knockdown of iGPX4 by siRNA alleviated lipid stress, ferroptosis and cell injury. Mechanistically, the triggered iGPX4 interacts with cGPX4 to facilitate the transformation of cGPX4 from enzymatic-active monomer to enzymatic-inactive oligomers upon lipid stress, and thus promotes ferroptosis. Co-immunoprecipitation and nano LC-MS/MS analyses confirmed the interaction between iGPX4 and cGPX4. Our results reveal a detrimental role of non-canonical GPX4 isoform in ferroptosis, and indicate selectively targeting iGPX4 may be a promising therapeutic strategy for MAFLD.
