Objective To construct a competency evaluation model for forensic practitioners,providing a reference for their training and assessment.Methods Based on the iceberg and onion models of com-petency,and with reference to Spencer's Competency Dictionary,literature research was conducted and focus group interviews were employed to preliminarily construct core indices and measurement items for evaluating the competency of forensic practitioners.The Delphi method was applied for two rounds of expert consultation to further refine the competency evaluation index system.The analytic hierarchy process(AHP)was used to calculate the weights of the indices.Results A competency evaluation model for forensic practitioners was constructed,consisting of 7 core indices,encompassing forensic skills,identification service capabilities,and the ability to apply relevant legal knowledge and 49 mea-surement items.The weights of the core indices and measurement items were determined.Conclusion The constructed competency evaluation model for forensic practitioners is scientifically sound and inno-vative,and has unique characteristics of forensic medicine compared with other medical models.

Objective:To establish a quality standard system for Descurainiae Semen under the requirements of German Pharmaceutical Codex (DPC); To compare the similarities and differences between DPC and the Pharmacopoeia of the People's Republic of China regarding the establishment of a quality standard system for TCM medicinal materials. Methods:Based on the requirements of DPC, and referring to the relevant methods of Pharmacopoeia of the People's Republic of China, the quality of 30 batches of Descurainiae Semen samples were assessed by observing the appearance and microscopic characteristics and determining their loss on drying, total ash content, and ash insoluble in hydrochloric acid. A TLC identification method was established based on a silica gel G TLC plate, using a developing agent composed of ethyl acetate, formic acid, and water in the ratio of 7:1.5:2.5 ( V/ V/ V). The method utilized rutin and quercetin as indicators for the System Suitability Test (SST), and took quercetin-3-O-β-D-glucose-7-O-β-D-gentiobioside and isorhamnetin 3-O-β-D-glucose-7-O-β-D-gentiobioside as the index. Based on the content determination method for Descurainiae Semen in the Pharmacopoeia of the People's Republic of China, a content determination method was established with quercetin-3-O-β-D-glucose-7-O-β- D-gentiobioside as the index. Results:The loss on drying for the 30 batches of samples ranged from 6.15% to 12.0%, with the total ash content ranged from 3.17% to 9.44%, and the ash insoluble in hydrochloric acid content ranged from 0.14% to 4.82%. The resolution of rutin and quercetin met the DPC's requirements for the SST criteria in TLC identification, and all batches of samples showed good separation of the index components. This method could effectively distinguish Descurainiae Semen from Lepidii Semen. Using modern chromatographic and spectroscopic techniques, the structure of the chromatographic peak adjacent to the component of the index (quercetin-3-O-β- D-glucoside-7-O-β-D-gentiobioside) was identified as descuraic anhydride B. The resolution between the two components in all batches of samples was greater than 3.1, which met the DPC's requirements for the SST criteria in content determination. The results of the methodological investigations met the requirements for content determination. The content of quercetin-3-O-β- D-glucose-7-O-β-D-gentiobioside in 30 batches of samples ranged from 0.062%-0.125%.Conclusion:The established quality standard system for Descurainiae Semen in this article is comprehensive, and meets the requirements of the DPC, which can be used for the quality control of Descurainiae Semen.

Objective : To investigate the protective effect of total glucosides of paeony ( TGP) on dexamethasone(DEX) ⁃induced liver injury in rats. Methods: Thirty SD rats were randomly divided into normal ( N) , DEX ,DEX + TGP (50 mg/kg) , DEX + TGP ( 100 mg/kg) , and DEX + TGP (200 mg/kg) groups , with 6 rats in each group. A rat model of liver injury was established by intraperitoneal injection of DEX ( 17. 5 mg/kg) . Serum levels of alanine aminotransferase ( ALT) , aspartate aminotransferase ( AST) , and alkaline phosphatase ( ALP) were measured , and the liver⁃to⁃body weight ratio was calculated. HE staining was performed to observe histopathological changes in the liver. The contents of malondialdehyde ( MDA) , superoxide dismutase ( SOD) , and glutathione (GSH) in liver tissues were determined. Western blot analysis was conducted to detect the expression levels of NADPH oxidase 4 ( NOX4 ) and endoplasmic reticulum stress⁃related proteins : glucose regulatory protein 94 homologous protein (CHOP) expression level in liver tissues. Results: Compared with the normal group , the DEX group exhibited significantly elevated serum levels of ALT , AST , ALP and liver⁃to⁃body weight ratio ( t = 14. 96 ,ing, degeneration , and necrosis ( t = 15. 49 , P < 0. 01) . Compared with the DEX group , there was no significant change in liver function biochemical indexes and liver histopathology in the TGP (50 mg/kg) treatment group. TGP treatment at 100 mg/kg and 200 mg/kg significantly attenuated these effects : both doses reduced ALT , AST , ALP and liver⁃to⁃body weight ratio( t = 3. 30 , 4. 13 , 7. 45 , 2. 97 , P < 0. 05 ; t = 8. 92 , 6. 45 , 8. 65 , 7. 47 , P < 0. 01) ,vealed that DEX administration significantly increased hepatic MDA levels ( t = 7. 06 , P < 0. 01) and NOX4 ex⁃pression ( t = 4. 23 , P < 0. 01) , whereas SOD activity ( t = 7. 78 , P < 0. 01) and GSH content ( t = 7. 92 , P <0. 01) were markedly suppressed. There was no significant change in the TGP (50 mg/kg) treatment group , TGP intervention at 100 mg/kg and 200 mg/kg effectively reversed these changes , lowering MDA and NOX4 levels( t = 3. 35 , 4. 30 , P < 0. 05 ; t = 5. 44 , 7. 44 , P < 0. 01) , while restoring SOD ( t200 mg/kg = 4. 04 , P < 0. 05) and GSH ( t = 4. 70 , P < 0. 05 ; t = 5. 50 , P < 0. 01) . Endoplasmic reticulum stress markers , including GRP94、GRP78、p- elF2α、CHOP ( t = 3. 31 , 6. 53 , 5. 18 , 3. 09 ; P < 0. 05 , 0. 01 , 0. 01 , 0. 05 ) , were significantly upregulated in the DEX group compared to the normal group. However, TGP treatment at 100 mg/kg and 200 mg/kg dose-dependent- ly suppressed the expression of GRP94、GRP78、p-elF2α、CHOP ( t = 3. 14 ,4. 95 , 3. 13 ,4. 25 , P < 0. 05 ; t = 4. 03 , 7. 48 ,4. 68 ,5. 10 ,P < 0. 01) expression levels were significantly reduced compared to the DEX group , and there was no significant change in the TGP (50 mg/kg) treatment group. Conclusion TGP exerts protective effects a- gainst DEX-induced liver injury , and its mechanism is likely mediated by suppressing hepatic oxidative stress and endoplasmic reticulum stress triggered by DEX in rats.

BACKGROUND:With the continuous progress of science and technology,the introduction of new technologies and methods will bring more possibilities and new breakthroughs for the application of shape memory alloys in the fields of assistive and rehabilitation. OBJECTIVE:To review the application status of shape memory alloys in assistive and rehabilitation equipment,discuss their main methods,techniques and results,summarize and put forward suggestions,hoping that shape memory alloys can be continuously optimized and bring more new changes for the development of assistive and rehabilitation equipment. METHODS:WanFang,PubMed,and Web of Science databases were searched by computer."Shape memory alloys,application progress,orthodontics,orthopedic,prosthesis,rehabilitation,properties,implantation,mechanical properties,nickel-titanium memory alloys,actuation"were used as Chinese search terms."Shape memory alloys,application,orthodontics,orthopedic,prosthetics,rehabilitation,properties,implant,drive,progress,prostheses"were used as English search terms.Finally,91 articles were included for review. RESULTS AND CONCLUSION:(1)Shape memory alloy has the characteristics of corrosion resistance,wear resistance,biocompatibility,fatigue resistance,kink resistance and other properties.Compared with other traditional materials(stainless steel,titanium alloy,cobalt-chromium alloy,etc.),shape memory alloy has lower elastic modulus and no biological toxicity,which is suitable for long-term implantation as an implant prosthesis.Due to its shape memory effect and excellent mechanical properties,it is mainly used as a driving element or as a bridge connecting the device and the human body in artificial limbs,orthoses and rehabilitation equipment.(2)The use of shape memory alloy drive elements can reduce the weight of the device,eliminate noise,easy to operate,easy to carry,better assist joint movement;compared with the use of pneumatic,hydraulic,and electrical drive methods of the device,it has obvious advantages.(3)In addition,shape memory alloy can produce permanent and stable stress during deformation.Compared with stainless steel,titanium alloy and aluminum alloy,shape memory alloy has a higher material recovery rate and does not need to be replaced and adjusted frequently,so it is more practical in the correction of deformity.(4)At present,shape memory alloy is most commonly used in orthosis,and the best clinical application effect is in stapes prosthesis.However,due to the limitations of technology and cost,shape memory alloys are rarely used in artificial limbs and rehabilitation equipment,and there is a lack of large sample size studies on the application effect.(5)Although shape memory alloys have been developed in the field of auxiliary and rehabilitation,there are still many problems:it is difficult to accurately control the shape memory alloys;the cooling speed of shape memory alloy is slow;the deformation speed of shape memory alloy cannot be controlled;there is a lack of comparative research and expert consensus on shape memory alloys with different properties;shape memory alloys are costly and expensive.(6)In the future,attention should be paid to the development of new shape memory alloys,increase comparative research,and use new technologies and methods(such as 4D printing)to solve the existing problems,so as to develop high-performance assistive devices and rehabilitation equipment.

Objective To explore the optimization strategy of Qishen Granules in treating coronary heart disease with heart failure(CHD-HF)based on data mining and the pathogenic"toxin"theory,and to predict its active components and mechanisms using network pharmacology.Methods Literature on traditional Chinese medicine(TCM)for treating CHD-HF was collected from relevant databases,and prescriptions were screened and established into a database according to inclusion and exclusion criteria.Frequency,association rules,and hierarchical clustering analyses were performed using the Ancient and Modern Medical Case Cloud Platform.Network pharmacology techniques were applied to screen potential targets of the optimized combination for treating CHD-HF,and carry out the targets and pathways enrichment analysis.Results A total of 336 articles and 339 prescriptions involving 191 herbs were included,with 12 herbs used more than 100 times.The core drug combinations for treating CHD-HF included Astragali Radix,Poria,Salviae Miltiorrhizae Radix et Rhizoma,Glycyrrhizae Radix et Rhizoma,Chuanxiong Rhizoma,etc,while commonly used detoxifying herbs included Leonuri Herb,Coptidis Rhizoma,etc.Association rule analysis yielded 10 two-item associations and 17 three-item associations;clustering analysis grouped the data into 5 categories.Based on data mining and the pathogenic"toxin"theory,the combination for treating CHD-HF was optimized to include Astragali Radix,Salviae Miltiorrhizae Radix et Rhizoma,Aconiti Lateralis Radix Praeparata,Glycyrrhizae Radix et Rhizoma,Coptidis Rhizoma,and Taraxaci Herba.Network pharmacology analysis identified 366 common targets between the optimized combination and CHD-HF,with 16 core targets screened out.Kyoto Encyclopedia of Genes and Genomes(KEGG)analysis revealed significant enrichment in pathways such as cancer pathways,lipid and atherosclerosis,Rap1 signaling pathway,hypoxia-inducible factor 1(HIF-1)signaling pathway,phosphatidylinositol-3-kinase/protein kinase B(PI3K/Akt)signaling pathway,Ras signaling pathway,and mitogen-activated protein kinase(MAPK)signaling pathway.Conclusion TCM treatment for CHD-HF primarily focuses on replenishing qi and warming yang,activating blood circulation and resolving fluid retention.Based on data mining results and the pathogenic"toxin"theory,the formulation strategy of Qishen Granules for treating CHD-HF was optimized,potentially exerting therapeutic effects through anti-inflammatory,anti-apoptotic,and anti-hypoxia physiological processes.

Objective To analyze the current status and hotspots of domestic research on traditional Chinese medicine(TCM)in treating chronic refractory wounds(CRW)over the past 10 years using bibliometric and visualized analysis methods.Methods Articles about TCM therapy for CRW issued by the core periodicals in recent 10 years were retrieved from CNKI,Wanfang and VIP databases.The parameters of annual issued papers,authors,institutions and keywords of the articles were counted with the bibliometric methods.And then the statistical results were presented as visualized graphs by using VOSviewer and CiteSpace software.Results A total of 404 articles were included in the study,and 313 institutions and 1 340 scholars participated in the research on the treatment of CRW with TCM.However,there was limited collaboration between the authors and institutions.Research hotspots mainly focused on the efficacy of TCM external therapies for diabetic foot and pressure ulcers,and discussions on syndrome differentiation,treatment principles and methods about internal treatment by various medical experts.The development and application of Chinese patent medicines,exploration of TCM medication patterns,and the evidence-based medical research on TCM are future research trends in the treatment of CRW with TCM.Conclusion Research on TCM treatment of CRW has attracted significant attention in recent years,but academic barriers exist between the authors and institutions.In the future,it is necessary to promote multicenter research collaboration,strengthen the exploration of experiences in acupoint selection,and conduct higher-level research,thus to provide more compelling evidence and enhance the efficacy of TCM in treating CRW.

ObjectiveAutism spectrum disorder (ASD) is a neurodevelopmental condition characterized by difficulties with communication and social interaction, restricted and repetitive behaviors. Previous studies have indicated that individuals with ASD exhibit early and lifelong attention deficits, which are closely related to the core symptoms of ASD. Basic visual attention processes may provide a critical foundation for their social communication and interaction abilities. Therefore, this study explores the behavior of children with ASD in capturing attention to changes in topological properties. MethodsOur study recruited twenty-seven ASD children diagnosed by professional clinicians according to DSM-5 and twenty-eight typically developing (TD) age-matched controls. In an attention capture task, we recorded the saccadic behaviors of children with ASD and TD in response to topological change (TC) and non-topological change (nTC) stimuli. Saccadic reaction time (SRT), visual search time (VS), and first fixation dwell time (FFDT) were used as indicators of attentional bias. Pearson correlation tests between the clinical assessment scales and attentional bias were conducted. ResultsThis study found that TD children had significantly faster SRT (P<0.05) and VS (P<0.05) for the TC stimuli compared to the nTC stimuli, while the children with ASD did not exhibit significant differences in either measure (P>0.05). Additionally, ASD children demonstrated significantly less attention towards the TC targets (measured by FFDT), in comparison to TD children (P<0.05). Furthermore, ASD children exhibited a significant negative linear correlation between their attentional bias (measured by VS) and their scores on the compulsive subscale (P<0.05). ConclusionThe results suggest that children with ASD have difficulty shifting their attention to objects with topological changes during change detection. This atypical attention may affect the child’s cognitive and behavioral development, thereby impacting their social communication and interaction. In sum, our findings indicate that difficulties in attentional capture by TC may be a key feature of ASD.
