Objective To develop a multiplex PCR assay for simultaneous detection of four intestinal parasites, including Giardia duodenalis, Cryptosporidium parvum, Enterocytozoon bieneusi and Moniezia, and to preliminarily evaluate its detection efficiency. Methods Four pairs of specific primers were designed based on the conserved sequences of the corresponding genes of G. duodenalis (GenBank accession number: XM_001710026.2), C. parvum (GenBank accession number: XM_626998.1), E. bieneusi (GenBank accession number: KJ719492.1) and Moniezia (GenBank accession number: OM296991.1) retrieved from the GenBank database, and a multiplex PCR assay for simultaneous detection of G. duodenalis, C. parvum, E. bieneusi and Moniezia was developed and optimized. A total of 116 fresh goat stool samples were collected from four goat farms in Zhanjiang City, Guangdong Province during the period from October to December 2022, including 96 samples used for evaluating the detection efficacy of the multiplex PCR assay, and 20 samples as baseline controls for sample testing. Genomic DNA extracted from 96 goat stool samples was tested using the single-target PCR assay and the developed multiplex PCR assay, and the sensitivity, specificity, positive predictive value, and negative predictive value of the multiplex PCR assay were evaluated for detection of G. duodenalis, C. parvum, E. bieneusi and Moniezia DNA in goat stool samples with the single-target PCR assay as the gold standard. Results The multiplex PCR assay developed in this study allowed simultaneous amplification of specific gene fragments of G. duodenalis, C. parvum, E. bieneusi and Moniezia, with 1 400, 755, 314 bp and 585 bp in sizes, respectively, and the detection limit was 10² and higher copies of parasite DNA clones, while the multiplex PCR assay was negative for gene amplification of Schistosoma japonicum, Fasciola hepatica, Echinococcus granulosus, Blastocystis hominis and Homalogaster paloniae. Single-target PCR assay and the developed multiplex PCR assay were employed to test DNA samples extracted from 96 goat stool samples, and single-target PCR assay tested positive in 40 goat stool samples (41.67%), including 39 positive samples tested with the multiplex PCR assay, with a mean coincidence rate of 97.50% (39/40). The multiplex PCR assay tested positive for G. duodenalis DNA in 26 goat stool samples (27.10%), C. parvum DNA in 22 samples (22.90%), E. bieneusi DNA in 24 samples (25.00%), and Moniezia in 9 samples (9.40%), which was consistent with the detection using the single-target PCR assay. The sensitivity, negative predictive value, and positive predictive value of the multiplex PCR assay were 96.15%, 95.83%, 100.00% and 100.00%, 98.90%, 98.92%, 100.00% and 100.00%, 100.00%, 100.00%, 100.00% and 100.00% for detection of G. duodenalis, C. parvum, E. bieneusi and Moniezia DNA in goat stool samples, respectively, if the single-target PCR assay served as the gold standard. Conclusion A highly sensitive and specific multiplex PCR assay has been developed for simultaneous detection of G. duodenalis, C. parvum, E. bieneusi and Moniezia in goats, which is suitable for rapid, large-scale screening of intestinal parasites in sheep stool samples.

Objective:To study the incidence and classification of chromosomal abnormalities in villi of missed abortion patients with assisted reproductive technology (ART) and natural conception (NC).Methods:Totally 637 patients with missed abortion villi from the Reproductive Center of the Third Affiliated Hospital of Zhengzhou University during January 2016 and January 2020 were collected and divided into ART group and NC group according to the mode of pregnancy in this retrospective cohort study. The ART group was further divided into artificial insemination by husband (AIH), in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI). Next generation sequencing (NGS) was used to detect the copy number variations (CNVs) and chromosome number abnormalities of chorionic villi of missed abortion. Results:Among 637 missed abortion chorionic villi, 45.2% (288/637) of the samples had normal chromosome and 54.8% (349/637) had abnormal chromosome. CNVs accounted for 3.8% (14/637) of the total samples, and chromosome number abnormalities accounted for 52.5% (335/637) of the total samples. The abnormal rates of villi chromosome in ART group and NC group were 59.2% (226/382) and 51.0% (130/255), respectively, and there was no significant difference between ART group and NC group ( P>0.05). The abnormal rates of villus chromosome in AIH group, IVF group and ICSI group were 52.1% (25/48), 58.9% (146/248) and 64.0% (55/86), respectively. Compared with NC group, the abnormal rate of villus chromosome in IVF group and ICSI group was increased, but there was no significant difference ( P>0.008). Conclusion:In general, ART did not increase the incidence of chromosomal abnormalities in missed abortion villi. However, compared with natural pregnancy and AIH assisted pregnancy, IVF/ICSI had a higher chromosomal abnormality in missed abortion villi.

Objective To explore the dynamic trend and main influencing factors of the prevalence of subthreshold depression after stroke,so as to provide reference for the primary prevention and nursing intervention of post-stroke depression. Methods A total of 123 stroke patients admitted to the department of neurology of Daqing People's Hospital from September 2017 to June 2018 were selected by convenience sampling method. Major Depressive Disorder Scale (CES-D), Hamilton Depression Scale (HAMD-17), Behavioral Inhibition System and Behavioral Activation System Scale (BIS/BAS) and National Institutes of Health Stroke Scale (NIHSS) were applied in the investigation. Results The prevalence of subthreshold depression after stroke at baseline, 3 months and 6 months was 25.6%,18.6% and 20.4% respectively, and there was no statistical significant in the difference in prevalence at each time point (P＞ 0.05). The results of regression analysis showed that, at the time point of 2 weeks after stroke, gender, age and behavioral activation level were the main factors of subthreshold depression after stroke; after 3 months, age and behavioral activation level were the main factors of subthreshold depression after stroke; after 6 months, the number of complications and the level of behavioral activation were the main factors of subthreshold depression after stroke. Conclusions The prevalence rate of post-stroke subthreshold depression decreased first and then increased with time. The main factors of post-stroke subthreshold depression were different at each time point, and medical staff should treat differently according to different time points, so as to achieve the primary prevention of post-stroke depression.

Objective To explore the relatianship of social anxiety and parental rearing style and self-es-teem among medical students, and to provide theoretical guidance for students' mental health. Methods 346 medical students were assessed with interaction anxiousness scale(IAS), Egala minnen on bardndosnauppforstran (EMBU) and self-esteem scale (SES).
