ObjectiveTo explore quality difference factors of Perillae Caulis based on the contents of multiple chemical components and comprehensively evaluate the quality. MethodsA total of 32 batches of Perillae Caulis samples were collected from 12 producing areas such as Hebei， Anhui and Guangdong， and their diameter range， epidermis color and producing areas were recorded. Total flavonoids， total phenols， volatile oils， 5 active components and 84 volatile components in 32 batches of samples were quantitatively or semi-quantitatively determined by colorimetry， ultra performance liquid chromatography-photodiode array detector（UPLC-PDA） and gas chromatography-mass spectrometry（GC-MS）. Then the differences between the contents of these components were analyzed by principal component analysis（PCA） and non-parametric test. According to the weights of the index components determined by PCA model， entropy weight-technique for order preference by similarity to ideal solution（TOPSIS） model was constructed to evaluate the quality of Perillae Caulis with different characters and origins. ResultsThere were significant differences in the composition of Perillae Caulis with different diameters， epidermis colors and producing areas， and 9 differential components were screened out， including 6 index constituents（total flavonoids， total phenols， caffeic acid， scutellarin， rosmarinic acid and luteolin） and 3 volatile components（caryophyllene oxide， （-）-humulene epoxide Ⅱ， 14-hydroxycaryophyllene）， of which 6 index constituents were higher in samples with small diameter， purple-brown epidermis and southern origin， while the contents of 3 volatile components were higher in samples with large diameter， dark-brown epidermis and northern origin. A significant difference was shown in the model scores of different diameters， epidermis colors and origins（P<0.05）， and the scores of Perillae Caulis with small diameter and purple-brown epidermis from southern area， especially Guangdong， had a high score. ConclusionThere are significant differences in the composition and content of chemical constituents between different diameters， epidermal colors and production areas of Perillae Caulis， samples showing small diameter， owing purple-brown epidermis， and originating from Guangdong were of higher-quality due to their higher content of 8 key indices.

This paper discusses the treatment of polycystic ovary syndrome(PCOS)based on the midnight-noon ebb-flow theory.The midnight-noon ebb-flow theory is a Chinese medicine science that combines the time and space of nature with the internal rhythm of the human body.PCOS is characterized by disappearance of the reproductive monthly rhythm.Its etiology is based on kidney deficiency.The key to its pathogenesis is the excess of yin and deficiency of yang,the hyperactivity of yang and deficiency of yin,and the lack of smooth connection between yin and yang.PCOS patients have circadian rhythm disorders,and the oscillation of the core clock gene is attenuated,which leads to the interruption of the circadian rhythm gene in the ovary,the imbalance of yin and yang trans-formation in the kidney,and the asynchrony of qi and blood flow with the time rhythm.Therefore,the treatment focuses on harmonizing yin and yang and rebuilding the normal reproductive rhythm of women.Using the midnight-noon ebb-flow theory,combined with the reproductive physiological characteristics of women,choosing different drug administration time and selecting meridians and acupoints according to the time will be helpful to unlock the"time code"of the female reproductive system,and assist clinical menstruation regu-lation,pregnancy and treatment of diseases.

ObjectiveTo investigate the current status and development needs of evidence-based medicine （EBM） capability in ethnic minority medicine， and explore effective strategies to enhance EBM capability in this field. MethodsThe questionnaire survey was conducted in various ethnic minority medical institutions and research organisations. The questionnaire covered three dimensions， firstly， perceptions and attitudes towards evidence-based medicine； secondly， advantages and challenges in the development of ethnic minority medicine； thirdly， demands and recommendations for enhancing evidence-based medicine capability in ethnic minority medicine. ResultsA total of 501 valid questionnaires were collected， of which 103 questionnaires were collected by re-sending to minority medicine regions with insufficient participation. The questionnaires included 354 responses （70.66%） from practitioners of minority medicine， including Tibetan medicine， Mongolian medicine， Uyghur medicine， Zhuang medicine， and Korean medicine. Among the 501 questionnaires， 146 respondents （29.14%） indicated that they knew about EBM， 355 respondents （70.86%） had either a "general understanding" or had "not heard about" EBM before， and 469 respondents （93.61%） believed that introducing ECM could promote the development of ethnic minority medicine. The primary challenge in promoting EBM in the field of ethnic minority medicine is the lack of professionals in EBM and a lack of understanding of how to apply it into clinical practice （442 respondents， 88.22%）. In the 9-point importance rating for enhancing evidence-based abilities， high scores were achieved in standardization of clinical practice guidelines （7.50±1.90） and methods for sample sizes in clinical research （7.45±1.90）. Regarding the demand for improving clinical research literacy， expert academic lectures， and experience sharing （404 respondents， 80.64%） and evidence-based methodology monographs on ethnic minority medicine （401 respondents， 80.04%） were emphasized. ConclusionsPractitioners in ethnic minority medicine hold a positive attitude towards integrating EBM. However， there remains substantial room for the education and dissemination of EBM. Enhancing evidence-based capabilities can be achieved through specific measures such as cultivating or recruiting talents in EBM， establishing evidence-based support platforms for clinical research， organizing regular academic lectures and exchanges， and strengthening the construction of theoretical frameworks and evaluation systems tailored to ethnic minority medicine， thereby following a path of evidence-based practices aligned with the unique characteristics of ethnic minority medicine.

【Objective】 To investigate the development of adaptability in children aged 2 - 6, and to explore its influencing factors, so as to provide reference for promoting the development of adaptability in young children. 【Methods】 Data were from the National Nutrition and Health Systematic Survey for Children in China, and 3 319 children aged 2 - 6 and their parents from 28 sites across 14 provinces were recruited in this study.The Development Scale for Children Aged 0 - 6 years (WS/T 580-2017) was used to measure the developmental quotient of children′s adaptive ability, and a survey questionnaire was used to collect relevant information about children and their parents. 【Results】 Among 3 319 children aged 2 - 6, the proportion of slightly low or low level of adaptability, moderate adaptability development, good and excellent adaptability development was 7.68%,66.25% and 26.06%, respectively.The proportion of children aged 5 - 6 with good and excellent adaptability was lower in 3-year-old and 4-year-old groups (χ²=59.29, P<0.05).Multiple stepwise linear regression showed that children′s gender (β=0.06), gestational age of birth (β=-0.05), only child (β=-0.04), left-behind child (β=-0.04), the main caregiver (β=-0.06), and the education level of parents (β=0.09, 0.10), whether parents actively pay attention to children′s emotions (β=-0.06) and whether children play with homemade toys (β=-0.04) were the influencing factors of children′s adaptive development quotient.Girls, full-term children, only children, non-left-behind children, children with parents as main caregivers, parents with a high level of education, parents who often take the initiative to pay attention to children′s emotions, and children who play with homemade toys had a higher level of adaptability development quotient. 【Conclusions】 The development level of adaptability in children aged 2 - 6 in China is mostly above the average level and is related to multiple factors.Targeted intervention work can be carried out on relevant factors in order to promote the development of children′s adaptability.

Objective:To understand the prevalence and characteristics of Rhinovirus (HRV) infection in influenza-like Illness (ILIs) patients in Mianyang, Sichuan province, China.Methods:Throat swabs were collected from patients of ILIs in sentinel hospitals in Mianyang during 2021—2022. Real-time fluorescence quantitative PCR was used to detect 16 common pathogens. The VP4/VP2 coding region genes of HRV positive samples were amplified by nest PCR. The phylogeny, consistency and amino acid variation of different serotypes were analyzed and compared with reference sequences from GenBank database.Results:A total of 332 ILIs′ samples were collected with a virus detection rate of 58.73% (195/332) in Mianyang. Among them, 23 samples (23/332) were HRV-positive, and 18 VP4/VP2 sequences of HRV strains were successfully amplified. It was found that 13 HRV serotypes were detected in ILIs samples in Mianyang, which belonged to three genotypes, namely HRV-A (12 strains), HRV-B (5 strains) and HRV-C (1 strain).Conclusions:HRV was one of the pathogens of ILIs cases in Mianyang during 2021—2022, with HRV-A types as the dominant strains.

Objective To explore the value of shear wave elastography(SWE)in the early assessment of hepatic and renal fibrosis in patients with metabolic associated fatty liver disease(MAFLD).Methods A total of 52 MAFLD patients admitted to the Second Affiliated Hospital of Wenzhou Medical University from July 2023 to May 2024 were selected as MAFLD group,and 40 non-MAFLD patients treated during the same period were served as control group.General information,laboratory data and ultrasound data were collected and compared between two groups.The differences as well as the correlation of the indicators between two groups were compared.The value of SWE in hepatic fibrosis and renal fibrosis in MAFLD patients was assessed.Results Liver function indicators,uric acid and aspartate aminotransferase-to-platelet ratio index(APRI)in MAFLD group were higher than those in control group(P＜0.01);There were no statistically significant differences between two groups in fibrosis 4 index,estimated glomerular filtration rate,serum creatinine and blood urea nitrogen(P＞0.05).The brightness of the liver,liver-kidney ratio,and liver elasticity value were higher in MAFLD group than those in control group(P＜0.05);There was no significant difference in the elasticity value of the right renal cortex between two groups(P＞0.05).Liver elasticity values was positively correlated with alanine aminotransferase(ALT);The liver-kidney ratio was positively correlated with body mass index(BMI),ALT,aspartate aminotransferase,alkaline phosphatase,y-glutamyl transferase and APRI.No significant correlation was found between the right renal cortex elasticity and BMI,estimated glomerular filtration rate,serum creatinine,blood urea nitrogen,or serum uric acid.Conclusion SWE helps in early identification of liver hardness in the MAFLD patients.But the application of SWE in early renal fibrosis in the MAFLD patients needs further evaluation.

Objective To analyze the composition of the aqueous extract of Polygonatum Cyrtonema Hua(PCHE)and evaluate its antitumor activity in vitro and in vivo.Our aim is to provide a theoretical basis for the further development and utilization of Polygonatum Cyrtonema Hua.Methods(1)PCHE was prepared by aqueous extraction,and the chemical composition of PCHE was analyzed by UPLC-Q-TOF/MS and phenol-sulfuric acid method.The inhibitory activity on tumor cells proliferation of PCHE was detected by CCK-8 assay.Cell cycle and apoptosis were detected by flow cytometry,and the expression of apoptosis-related proteins Bcl-2 and Bax was detected by Western Blot.The inhibitory activity of PCHE-containing serum on cell proliferation was detected.(2)A B16 tumor-bearing mice model was constructed and model mice were randomly divided into the model group(saline),the positive drug group(CTX:50 mg·kg-1),and PCHE low-,medium-,and high-dose groups(55.9,111.8,223.6 mg·kg-1),and treated by gavage for 7 days.Changes in body weight and tumor volume of mice were observed during the treatment period.The mice were executed after the treatment,and the histopathological changes of heart,liver,spleen,lung,kidney and tumor were observed by hematoxylin-eosin(HE)staining.The protein expression of Bcl-2 and Bax in tumor tissues was detected by immunohistochemistry(IHC).Results The polysaccharide content of PCHE reached(10.07±1.3)%,and the flavonoid content was(0.044±0.004)%,and thirty-nine components were detected by UPLC-Q-TOF/MS,which contained antitumor components such as flavonoids(baicalein,quercetin,luteolin and rutin),organic acids(ferulic acid)and polyphenols(gallic acid),etc.PCHE exhibited the inhibitory effects on Hela,A549,4T1,B16,MFC and HepG2 cells,among which the inhibitory effect on B16 cells was the most significant(P＜0.001),and PCHE induced cell cycle arrest at G0/G1 phase in B16 cells(P＜0.001).The results of double-staining flow cytometry and Western Blot showed that PCHE significantly promoted apoptosis of B16 cells,decreased the expression of Bcl-2,and promoted the expression of Bax(P＜0.01,P＜0.001).and PCHE constituents absorbed into blood also had an inhibitory effect on B16 cells(P＜0.001).In addition,the results of in vivo activity assay showed that different doses of PCHE could inhibit tumor growth,induce tumor cell necrosis,reduce Bcl-2 expression,and increase Bax expression compared with the model group.Conclusion The ingredients in PCHE are abundant.It contains a variety of antitumor active ingredients,which can inhibit tumor growth,induce tumor cell apoptosis,show strong anti-tumor effects and be worthy of in-depth study.
