OBJECTIVE To promote the standardization of the"Indications"section in package inserts for Chinese patent medicines and ensure rational clinical and patient use.METHODS The"Function and Indications"information of package inserts for Chinese patent medicines was retrieved and collected from the 2020 edition of the Chinese Pharmacopoeia(Volume Ⅰ)and various national and regional standards.Identification criteria were established for syndrome,pathogenesis,disease name,and symptom terminology in the"Indications"section.Microsoft Office Access 2021 was utilized to create query tables for manual extraction of terminological elements,followed by the construction of a three-tier classification system for"Indications"descriptions.A standardized template for"Indications"was developed through quantitative analysis.RESULTS & CONCLUSIONS A total of 9 851 valid package inserts for Chinese patent medicines were included.Among these,the majority(7 991)contained symptom terminology,followed by disease names(5 867)and pathogenesis descriptions(5 167).Within disease name terminology,Western medical disease names predominated(4 446),followed by traditional Chinese medicine disease names(2 018).The"Function and Indications"content of 6 962 package inserts complied with existing requirements.Notably,the secondary classifications of"disease name",as well as the tertiary classification of"disease name+symptoms"and"symptoms",failed to meet established standards.Two standardized templates for"Indications"were formulated based on pathogenesis and syndrome:"pathogenesis+disease name+symptoms"and"disease name+syndrome+symptoms".The"Indications"section should provide complete and accurate information,adhere to standardized formatting,and employ appropriate conjunctions and punctuation.For non-prescription Chinese patent medicines,package inserts should be categorized into professional and patient versions.These measures will facilitate the standardization of"Indications"descriptions and advance the overall package inserts for Chinese patent medicines documentation.

Objective This article focuses on the investment promotion policies at the municipal and district levels(park management committee level)of biomedical industrial parks in China at different development stages.It aims to reveal the characteristics and patterns of these policies,providing a reference for the formulation of development policies for biomedical industrial parks in China.Methods A total of 166 policies issued by three biomedical industrial parks(LifeBay,Nanjing Biotech and Pharmaceutical Valley and BioBay)from January 2013 to June 2023 were coded and quantitatively analyzed using a three-dimensional analytical framework of policy tool-development stage-issuing body.Results At the municipal level,the use of policy tools by administrative development is supply-oriented and environmental-oriented.At the district level,the types of policy tools used are closely related to the stage of the park.Start-up parks have a high proportion of supply-based policy tools,growth parks have a high proportion of demand-based policy tools,and mature parks have a high proportion of environmental policy tools.Conclusion Policy insights such as the strategic use of policy tools according to the development stage of the park,the optimization of the internal structure of the tools and the enhancement of the complementarity and coordination among the tools,and the use of policy tools to promote industrial agglomeration in line with local realities are put forward.

Objective:To sinicize the adolescent personality structure questionnaire(APS-Q), and to examine the psychometric properties of APS-Q among Chinese adolescents.Methods:APS-Q was sinicized and the Chinese version of APS-Q was used for investigation.A sample of 1 207 adolescents were investigated firstly and randomly divided into sample 1 ( n1=590) and sample 2 ( n2=617) for exploratory factor analysis and confirmatory factor analysis, respectively. Moreover, the sample 3 ( n3=420) was collected to conduct confirmatory factor analysis for the second time.Sample 4( n4=83) was used to assess the test-retest reliability of APS-Q. The Chinese big five personality inventory-15 (CBF-PI-15), generalized anxiety disorder-7 (GAD-7) and patient health questionnaire-9 (PHQ-9) were used as criterion tools. Both SPSS 21.0 and Mplus 7.4 software were used for the data analysis. Results:Item analysis showed that the CITCs for items 27, 31 and 35 were low.Exploratory factor analysis suggested that after deleting items 3, 4, 21, 22, 24, 25, 26, 27, 31 and 35, the revised APS-Q was consisted with 25 items, covering 6 dimensions, which were investment and goals, aggression, sense of self, relationship with family, relationship with friends, and self-acceptance, respectively. Confirmatory factor analysis supported the six-factor model fitted well (sample 2: χ2/ df=1.94, RMSEA=0.04, CFI=0.94, TLI=0.93, and SRMR=0.05; sample 3: χ2/ df=2.12, RMSEA=0.05, CFI=0.95, TLI=0.92, and SRMR=0.06). Multigroup CFA indicated that the six-factor structure of APS-Q had strict measurement invariance across sex. The scores of APS-Q were significantly correlated with big five personality, depression, and anxiety(all P<0.05). The total score of APS-Q demonstrated satisfactory internal consistency (α=0.90, ω=0.90, split-half reliability=0.82, MIC=0.27) and test-retest reliability ( r=0.84), while the subscale scores of APS-Q showed acceptable internal consistencies (α=0.71-0.82, ω=0.72-0.82, split-half reliabilities=0.60-0.79, MIC=0.36-0.52) and test-retest coefficients ( r=0.66-0.77). Conclusion:The Chinese version of APS-Q can be used as a reliable and valid measurement to assess personality function for Chinese adolescents.

Objective To investigate the relationship between metaphor comprehension and theory of mind in school-aged children with autism spectrum disorder(ASD).Methods A total of 50 children with ASD(ASD group)and 50 age-and gender-matched typically developing(TD)chil-dren(TD group)were recruited from special education institutions in Hangzhou between August,2023 and No-vember,2024.Metaphor comprehension was assessed using a visual picture paradigm,covering conceptual,shape,appearance and mixed metaphors.The theory of mind was assessed using unexpected content/place tasks.Results The total score of metaphor comprehension was lower in ASD group than in TD group(Z=-5.625,P<0.001),particularly for shape,appearance and mixed metaphors(|Z|>5.625,P<0.01);as well as the scores of theory of mind(|Z|>5.255,P<0.001).There was positive correlation between the total score of theory of mind and total score(r=0.352,P<0.05),shape score(r=0.299,P<0.05)and mixed score(r=0.330,P<0.05)of metaphor comprehension.Regression analyses showed that the total score of theory of mind positively predicted total score(β=0.310,P<0.05),shape score(β=0.103,P<0.05)and mixed score(β=0.330,P<0.05)of metaphor com-prehension.Conclusion Children with ASD delayed in metaphor comprehension,which associates with deficits in theory of mind.

Screening carbonyl reductases with the ability to catalyze the reduction of complex carbonyl compounds is of great significance for the biosynthesis of R-tolvaptan(R-TVP). In this study, the target carbonyl reductase in the crude enzyme extract of rabbit liver was separated, purified, and identified by ammonium sulfate precipitation, gel-filtration chromatography, ion exchange chromatography, affinity chromatography, and protein mass spectrometry. With the rabbit liver genome as the template, the gene encoding the carbonyl reductase rlsr5 was amplified by PCR and the recombinant strain was successfully constructed. After RLSR5 was purified by affinity chromatography, its enzymatic properties were characterized. The results indicated that the gene sequence of rlsr5 was 972 bp, encoding a protein with a molecular weight of 40 kDa. RLSR5 was a dimeric protein, and each monomer was composed of a (α/β)₈-barrel structure. RLSR5 could asymmetrically reduce 7-chloro-1-[2-methyl-4-[(2- methylbenzoyl)amino]benzoyl]-5-oxo-2,3,4,5-tetrahydro-1H-1-benzazepine (prochiral ketone, PK) to synthesize R-TVP. The specific activity of the enzyme was 36.64 U/mg, and the optical purity of the product was 99%. This enzyme showcased the optimal performance at pH 6.0 and 30 °C. It was independent of metal ions, with the activity enhanced by Mn²⁺. This study lays a foundation for the biosynthesis of tolvaptan of optical grade.
