ObjectiveAngelicae Sinensis Radix， a commonly used medicinal herb with both medicinal and edible properties， is frequently adulterated in the market， severely affecting the clinical efficacy of preparations. While qualitative identification techniques for adulterants and counterfeits are now relatively mature， quantitative detection methods for adulterated processed products remain unexplored. Quantitative detection research of Angelicae Sinensis Radix and its primary closely related adulterant， "Tu Danggui" （Angelica gigas）， was conducted to establish a herbal quantitative molecular detection （Herb-Q） method for Angelicae Sinensis Radix and its processed products， providing a model for the establishment of quantitative detection technologies for Angelicae Sinensis Radix and related health products. MethodsThe specific single-nucleotide polymorphism （SNP） loci of Angelicae Sinensis Radix and Angelica gigas Nakai were screened based on the complete chloroplast genome sequence. The specific SNP loci of Angelicae Sinensis Radix were selected for quantitative methodological investigations （linearity， limit of quantification， limit of detection， and reproducibility） by mixing the powder of the herbs with different adulteration ratios. Huoxue Zhitong powder with three distinct adulteration ratios （15%， 25%， and 35%） was utilized to ascertain the precision of the Herb-Q method for the quantitative detection of Chinese patent medicines containing Angelicae Sinensis Radix. ResultsBy comparing the 123 chloroplast genome sequences of Angelicae Sinensis Radix， based on the principles of intraspecies conservation， interspecies specificity， and meeting the requirements of pyrophosphate high-throughput sequencing， it was determined that 9 674^th locus （A/G） in the chloroplast genome sequence NC_042826.1 and 38 592^nd locus （T/C） in the chloroplast genome sequence NC_029393.1 could be the exclusive molecular identification loci of Angelicae Sinensis Radix and Angelica gigas Nakai， respectively. The linear relationship R² of the Herb-Q method established by selecting the specific 9 674^th locus （A/G） of Angelicae Sinensis Radix was 0.997 4 （R²>0.99）， indicating an excellent linear relationship. The limits of quantification and detection were established at 2.0%， exhibiting excellent reproducibility ［relative standard deviation（RSD）<2.0%］. The established quantitative system based on the Herb-Q method detected the adulteration amount of counterfeit A. gigas in the Huoxue Zhitong powder， with an average deviation of 1.3% for three molecular quantitative replicates. ConclusionThis research demonstrates that the Herb-Q quantitative detection method established based on the 9 674^th locus （A/G） in the chloroplast genome sequence NC_042826.1 of Angelicae Sinensis Radix has good applicability， objectivity， and accuracy for Angelicae Sinensis Radix and A. gigas， and its processed products. This method has the capacity to provide technical support for the quantitative detection of commercially available Angelicae Sinensis Radix derivatives， including traditional Chinese medicinal preparations， dietary supplements， and nutraceuticals.

Objective:To compare the curative effect of local anesthesia Lichtenstein, modified Kugel and general anesthetic transabdominal preperitoneal(TAPP) hemioplasty in the treatment of primary unilateral inguinal hernia in elderly patients.Methods:Six hundred and twenty-one patients with unilateral primary inguinal hernia admitted at Second Hospital of Tianjin Medical University from January 2021 to December 2023 were randomly divided into 3 groups before operation: Lichtenstein group, Modified-Kugel group, TAPP group,207 patients in each group. The clinical data were compared.Results:The average operation time of the Lichtenstein and modified Kugel hernia repair groups was significantly shorter than that of TAPP group ( P<0.01), and the hospitalization cost was also significantly lower than that of TAPP group. The postoperative pain score, time spent in the ground and hospital stay in TAPP group were significantly lower than those in Lichtenstein and modified Kugel groups ( P<0.05). There were no serious complications in the 3 groups. Conclusions:Three kinds of hernia repair are all safe and effective in the treatment of elderly patients with unilateral primary inguinal hernia. TAPP has lighter postoperative pain and quicker recovery. Lichtenstein and Modified-Kugel hernia repair under local anesthesia are suitable for those who cannot tolerate general anesthesia.

Objective To analyze the level of occupational health literacy (OHL) and mental health status in key populations in Jiangsu Province, and explore the impact of OHL on occupational stress, depressive symptoms, anxiety symptoms and insomnia symptoms. Methods A total of 11 181 workers from Jiangsu Province from April to December 2023 were selected as the research subjects using a combination of stratified cluster random sampling and probability proportional sampling method. The OHL levels of the workers, as well as their occupational stress, depression symptoms, anxiety symptoms and insomnia symptoms, were investigated using the Occupational Health Literacy Questionnaire of National Key Populations (including Occupational Health Literacy Scale, Core Occupational Stress Scale, Patient Health Questionaire-9, Generalized Anxiety Disorder 7-item Scale, and Self-Sleep Management Questionnaire). Results The OHL level of the research subjects was 41.7%, and the literacy levels of the four dimensions of occupational health legal knowledge, basic knowledge of occupational health protection, basic skills of occupational health protection, and healthy working style and behavior were 40.6%, 76.4%, 28.0% and 54.4%, respectively. The detection rates of occupational stress, depression symptoms, anxiety symptoms and insomnia symptoms were 21.8%, 17.7%, 26.4% and 29.6%, respectively. The result of multivariable logistic analysis showed that participants with adequate OHL had a lower risk of occupational stress, depressive symptoms, anxiety symptoms, and insomnia symptoms than those without adequate OHL (all P<0.01) after controlling individual and occupational confounding factors. The odds ratios and their 95% confidence intervals were 0.448(0.402-0.499), 0.664(0.593-0.742), 0.705(0.639-0.777) and 0.885(0.809-0.969), respectively. Conclusion OHL is an independent influencing factor for occupational stress, depressive symptoms, anxiety symptoms and insomnia symptoms in key populations from Jiangsu Province. Effective measures should be taken to improve the OHL level of workers, to reduce the risks of occupational stress, depressive symptoms, anxiety symptoms and insomnia symptoms.

Objective To compare the clinical efficacy of laparoscopic high ligation of the hernia sac combined with intraperitoneal onlay mesh(IPOM)and local anesthesia Lichtenstein repair for the treatment of inguinal hernia after total cystectomy in male patients.Methods A total of 59 male patients who underwent total cystectomy were included in this study and randomly divided into two groups:the laparoscopic high ligation of the hernia sac combined with IPOM group(IPOM group,30 cases)and the local anesthesia Lichtenstein repair group(local anesthesia group,29 cases).The patient age,surgical time,postoperative ambulation time,visual analogue scale score for pain on the 1st to 3rd days and 3 months after operation,time to first mobilization post-operation,pain scores on postoperative day 1,2 and 3,pain scores at 3 months post-operation were observed and compared between the two groups.Data of intraoperative blood loss,hospital stay,time to return to daily activities,total surgery costs,recurrence rates at 1 year after operation and complications were also observed and compared in two groups of patients.The results were analyzed to determine the optimal surgical method.Results The IPOM group demonstrated better outcomes in terms of surgical time,time to first mobilization,pain scores on postoperative days 1,2 and 3,pain scores at 3 months,intraoperative blood loss,hospital stay and time to return to daily activities compared to those of the local anesthesia group(P＜0.01).However,the total cost of the operation was higher in the IPOM group than those of the local anesthesia group(P＜0.01).There were no significant differences in postoperative complications between the two groups(P＞0.05).The recurrence rate of the IPOM group one year after surgery was better than that of the local anesthesia group(P＜0.05).Conclusion Laparoscopic IPOM with high ligation of the hernia sac is superior to the traditional Lichtenstein repair in reducing postoperative pain and recurrence rates.This surgical method should be the first choice when economic conditions permit.

Objective:The development and application of end-of-life patient decision aids for elderly were systematically reviewed and analyzed in order to supply guidance for the design of localized patient decision aids in China.Methods:Using the Scoping Review Guidelines as a methodological framework, a systematic search was conducted across databases including China National Knowledge Infrastructure, Wanfang, China Biology Medicine, PubMed, Web of Science, Embase, Cochrane Library, CINAHL, and BIOSIS. The search period covered from the inception of these databases to October 31, 2023. Two professionally trained researchers were responsible for screening, extracting, and organizing the retrieved literature.Results:A total of 5 studies on decision aids were included. These primarily employed paper graphics, interactive web pages, or multimedia slides as formats. The content encompassed various aspects such as palliative care options along with their pros and cons, assisting patients in clarifying their personal values, encouraging patients to document their decision-making preferences, and initiating end-of-life conversations with family members. Age-friendly design strategies were adopted in 4 studies; efficacy was validated in 3 studies, and in two of these studies, significant improvements were observed in engagement of patients (or substitute decision-makers) in ACP and the consistency of decision preferences (both P< 0.05). Conclusions:End-of-life decision aids for elderly patients can improve decision-making outcomes to some extent, however, the form and quality standards of them need to be improved, and their long-term effect needs further research and verification. It is recommended that in the future, the needs for end-of-life decision-making should be properly assessed based on the health literacy level, and high-quality localized end-of-life decision aids should be developed and popularized.

Objective:To investigate and analyze the relationship between genotype and phenotype in patients with early-onset high myopia (eoHM) associated with hereditary eye diseases.Methods:A family-based study was conducted among 30 families diagnosed with eoHM at Department of Ophthalmology of People's Hospital of Ningxia Hui Autonomous Region from January 2022 to June 2023. Seven families (23.3%, 7/30), all probands, and their 14 parents were included. These seven families were unrelated. Detailed patient and family histories were collected. All participants underwent comprehensive ophthalmic examinations, including best-corrected visual acuity, color vision testing, fundus color photography, optical coherence tomography, fluorescein fundus angiography, and fundus autofluorescence imaging. Full-field electroretinography was performed in four cases. Peripheral venous blood samples were collected from patients and their parents for whole-genome DNA extraction and whole-exome sequencing. Potential pathogenic variants were identified, and their pathogenicity was analyzed and confirmed by Sanger sequencing. The pathogenicity of newly discovered gene variants was evaluated according to the guidelines of the American College of Medical Genetics and Genomics (ACMG). Literature on previously reported eoHM associated with hereditary eye diseases was reviewed to analyze the relationship between variant genes and clinical phenotypes.Results:Among the seven families, three exhibited X-linked inheritance, two showed autosomal recessive inheritance, and two demonstrated autosomal dominant inheritance. All the patients were male. Among the seven patients, one case each was identified with congenital stationary night blindness (CSNB), Bornholm eye disease, X-linked retinitis pigmentosa (XL-RP), cone-rod dystrophy, Knobloch syndrome, familial exudative vitreoretinopathy (FEVR), and Stickler syndrome. Genetic testing revealed nine gene variants highly correlated with the observed phenotypes. The genetic testing results revealed that all patients were found to carry nine gene variants highly associated with the phenotype, including: a hemizygous missense variant NYX c.647A>T (p.N216I) (M1), an OPN1LW LIAVA haplotype variant (M2), a hemizygous frameshift variant RPGR c.3096_3097del (p.E1033RfsTer45) (M3), compound heterozygous variants TTLL5 c.1588_1589del (p.L531EfsTer24) and c.850G>C (p.D284H) (M4, M5), compound heterozygous variants COL18A1 c.2118dup (p.G707RfsTer23) and c.3523_3524del (p.L1175VfsTer72) (M6, M7), a heterozygous missense mutation FZD4 c.1499C>T (p.T500I) (M8), and a heterozygous frameshift variant COL11A2 c.966dup (p.T323HfsTer19) (M9). Among them, M2, M4, M5, M8 and M9 were newly discovered mutation sites, and M1, M3, M6 and M7 were known mutation sites. According to the classification standards and guidelines of genetic variation issued by ACMG, M2, M3, M4, M6, M7, and M9 were judged to be pathogenic variants, while M1, M5, and M8 were of unknown clinical significance. Through literature review, it was found that eoHM was more common among the clinical phenotypes of 4 types of hereditary retinal diseases, including CSNB, Stickler syndrome, FEVR and XL-RP. Conclusion:eoHM is intricately associated with inherited eye diseases and may serve as the earliest indicator of such conditions.
