Objective To investigate the value of secreted frizzled-related protein 1(SFRP1),GATA binding protein 3(GATA3)combined with human papillomavirus deoxyribonucleic acid(HPV-DNA)in predicting the risk of postoperative recurrence of high-grade cervical intraepithelial neoplasia(CIN)with positive thin-prep cytologic test(TCT).Methods A total of 200 patients with high-grade CIN and positive TCT results from July 2021 to July 2023 were selected as study subjects.All patients underwent cervical conization,and were divided into recurrence group and non-recurrence group according to the recurrence status one year after surgery.The clinical data,HPV-DNA viral load,and the relative expression levels of SFRP1 mRNA and GATA3 mRNA in cer-vical tissues were compared between the two groups.The HPV-DNA viral load,SFRP1 mRNA,and GATA3 mRNA expression levels in patients with different CIN grades were compared,and their cor-relations with CIN grade and the risk of postoperative recurrence were analyzed.The predictive val-ues of SFRP1,GATA3,and HPV-DNA for the risk of postoperative recurrence were analyzed.Results Among 200 patients,2 were lost during the follow-up period.The recurrence group(n=30)had higher proportions of CIN grade Ⅲ,glandular involvement,positive surgical margins,high-risk human papillomavirus(HPV),higher HPV-DNA viral load,and a higher proportion of HPV positivity at 6 months after surgery compared with the non-recurrence group(n=168),and the differences were statistically significant(P＜0.05).The relative expression levels of SFRP1 mRNA and GATA3 mRNA in cervical tissues of the recurrence group were lower than those of the non-recur-rence group,and the differences were statistically significant(P＜0.001).The HPV-DNA level in pa-tients with CIN grade Ⅲ was higher than that in those with CIN grade Ⅱ,and the relative expres-sion levels of SFRP1 mRNA and GATA3 mRNA in cervical tissues were lower than those in patients with CIN grade Ⅱ,and the differences were all statistically significant(P＜0.001).Spearman cor-relation analysis showed that HPV-DNA was positively correlated with CIN grade(P＜0.001),while the relative expression levels of SFRP1 mRNA and GATA3 mRNA in cervical tissues were neg-atively correlated with CIN grade(P＜0.001).Logistic regression analysis showed that HPV-DNA,the relative expression levels of SFRP1 mRNA and GATA3 mRNA in cervical tissues were independ-ent influencing factors for the risk of postoperative recurrence(P＜0.001).The receiver operating characteristic(ROC)curve results showed that the areas under the curve(AUCs)for predicting the risk of postoperative recurrence by HPV-DNA,the relative expression levels of SFRP1 mRNA and GATA3 mRNA in cervical tissues were 0.787,0.781,and 0.764,respectively,with sensitivities of 80.00％,76.67％,and 76.67％,and specificities of 74.40％,73.81％,and 67.26％,respec-tively.The AUC for the combined prediction of the risk of postoperative recurrence by the three indica-tors was 0.924,with a sensitivity of 80.00％and a specificity of 93.45％,which was superior to the pre-dictive values of each indicator alone(Z=3.159,3.306,4.018,P＜0.001).Conclusion HPV-DNA,SFRP1,and GATA3 in cervical tissues have certain predictive values for the risk of postoperative re-currence in patients with high-grade CIN and positive TCT results,and combined detection can im-prove the predictive efficacy.

Purpose Hydrogen proton magnetic resonance imaging was used to study the brain metabolism of menstrual-related migraine(MRM)in different states,and to investigate its correlation with clinical features and estrogen and progesterone.Materials and Methods We recruited 36 patients with MRM diagnosed by neurology outpatient experts of the First Affiliated Hospital of Henan University of Science and Technology from April 2019 to August 2022,and also recruited 29 normal women with age-and education-matched.Proton magnetic resonance spectroscopy was used to assess neurochemical brain changes during interictal period(late follicular phase)and ictal period(perimenstrual phase)in them.The point resolved spectroscopic sequence was used to focus on the bilateral medial prefrontal cortex(mPFC)and bilateral thalamus.Sex hormone levels were collected on the same day of MRI acquisition.The ratios of NAA/Cr,GABA/Cr,Glx/Cr and Cho/Cr were observed.Metabolite changes and hormone levels were investigated among two groups.Furthermore,metabolite changes were investigated in a longitudinal design during the interictal period and ictal period.Results There were no significant differences in the levels of estrogen and progesterone both in the late follicular and perimenstrual periods.There were no significant differences in decline rate of them in perimenstrual periods between patients and normal people(P>0.05).During interictal period,the ratio of Cho/Cr in the region of left mPFC was lower significantly in the MRM group than that of control group(U=-2.957,P=0.003)and showed a significant negative correlation with attack frequency(r=-0.398,P=0.018).During ictal period,the women with MRM had significantly lower the ratio of GABA/Cr in the left mPFC and higher the ratio of Glx/Cr in the left thalamus compared to those of controls(U=-2.015,P=0.044;t=2.213,P=0.033).We found no significant correlations between these results and magraine characteristics(P>0.05).In addition,we found the ratio of GABA/Cr did not change(P>0.05),the ratio of Glx/Cr and Cho/Cr in right thalamus increased from interictal towards the ictal state for MRM patients(t=-2.181,P=0.038;Z=-2.414,P=0.016).Conclusion The present study suggests the existence of distinct cerebral metabolism states between MRM and control,and there are dynamic changes in cerebral metabolism with headache attacks.However,there is no significant difference in estrogen and progesterone from normal women,and its neural mechanism still needs to be further studied.

This paper analyzes a patient's clinical and laboratory characteristics with lumbar disc herniation invaded by Brucella in the bloodstream, causing brucellar spondylitis with paravertebral and psoas abscesses in Hebei Province in 2022. A 50-year-old male patient presented with lower back pain two months after physical exertion, and the symptoms were alleviated after bed rest but recurred intermittently. A Lumbar CT scan indicated disc protrusion, and the patient experienced multiple episodes of fever during this period. Twelve days before admission, the patient developed unexplained swelling pain and numbness in the right lower limb, which persisted despite bed rest. On October 21, 2022, tissue and abscess specimens were directly cultured and Gram-stained, along with blood culture, Brucella antibody testing, and CT imaging. Gram staining of the pus sample revealed tiny, sand-like bacterial bodies, suspected to be Brucella species. Paravertebral abscess samples and positive blood cultures were cultured on blood agar plates, yielding Brucella melitensis. Brucella antibody tests were positive. CT scanning of the lumbar vertebrae revealed bone destruction from L3 to L5, with swelling of the paravertebral soft tissues and left psoas muscle. The patient was diagnosed with brucellar spondylitis, with the accompanying paravertebral and psoas abscesses being a rare complication of brucellar spondylitis. Conservative treatment was ineffective, so surgery was performed to relieve nerve compression symptoms, along with the administration of anti-Brucella medication. The patient was discharged 15 days and continued anti-Brucella treatment post-discharge. One year follow-up showed the patient was cured with no recurrence. Brucellosis is characterized by sporadic outbreaks, with atypical clinical symptoms that can easily result in missed or incorrect diagnoses. Timely blood cultures are crucial for early diagnosis and effective anti-Brucella treatment to prevent disease progression and dissemination through the bloodstream, which could lead to multiple organ involvement, exacerbating the condition and hindering recovery.

The testis is pivotal for male reproduction, and its progressive functional decline in aging is associated with infertility. However, the regulatory mechanism underlying primate testicular aging remains largely elusive. Here, we resolve the aging-related cellular and molecular alterations of primate testicular aging by establishing a single-nucleus transcriptomic atlas. Gene-expression patterns along the spermatogenesis trajectory revealed molecular programs associated with attrition of spermatogonial stem cell reservoir, disturbed meiosis and impaired spermiogenesis along the sequential continuum. Remarkably, Sertoli cell was identified as the cell type most susceptible to aging, given its deeply perturbed age-associated transcriptional profiles. Concomitantly, downregulation of the transcription factor Wilms' Tumor 1 (WT1), essential for Sertoli cell homeostasis, was associated with accelerated cellular senescence, disrupted tight junctions, and a compromised cell identity signature, which altogether may help create a hostile microenvironment for spermatogenesis. Collectively, our study depicts in-depth transcriptomic traits of non-human primate (NHP) testicular aging at single-cell resolution, providing potential diagnostic biomarkers and targets for therapeutic interventions against testicular aging and age-related male reproductive diseases.
