Objective:To explore the application value of PAX1/JAM3 methylation detection by cervical self-collected specimen in cervical cancer screening and the management of premenopausal and postmenopausal women.Method:This study is a single center cross-sectional study. From January 2023 to November 2023, cervical self-collected and physician-collected specimens at the colposcopy clinic were detected the PAX1/JAM3 methylation (PAX1 m/JAM3 m) testing. The consistency between self-collected and physician-collected specimens for PAX1 m/JAM3 m detection were compared based on histopathology. In addition, the clinical efficacy of methylation detection with high-risk human papillomavirus (hrHPV), liquid-based cytology (LBC), and their combination for cervical cancer screening were compared in the study. Results:A total of 301 women were recruited to undergo referral colposcopy examination, and statistical analysis was conducted on 272 women with pathological and diagnostic information. Among them, 102 cases (37.5%) were diagnosed as normal cervical tissue or chronic cervicitis, 72 cases (26.4%) were cervical intraepithelial neoplasia grade 1 (CIN1), 43 cases (15.8%) were CIN2, 29 cases (10.7%) were CIN3, and 26 cases (9.6%) were cervical cancer. According to the minimum quantity formula, they were divided into a consistency cohort of 81 participants and a validation cohort of 191 participants. The consistency between cervical self-collected and physician-collected specimens for detecting PAX1 m/JAM3 m. Results from spearman correlation analysis showed a positive correlation between the self-collected and physician-collected results of PAX1 m/JAM3 m detection, and the correlation coefficient R values are 0.858 ( P<0.001) and 0.828 ( P<0.001). The sensitivity and specificity of PAX1 m/JAM3 m detection for diagnosing CIN2 or more severe lesions (CIN2+) were 77.6% [95% confidence interval ( CI) 65.3%-86.4%] and 87.2% (95% CI 80.5%-91.9%), respectively. In clinical performance comparison, the sensitivity of PAX1 m/JAM3 m combined with HPV16/18 detection, 89.7% (95% CI 79.2%-95.2%), was the same as that of hrHPV detection in CIN2+and 96.0% (95% CI 80.4%-99.3%) in CIN3+, which is higher than 92.0% (95% CI 75.0%-97.8%) of hrHPV and 82.6% (95% CI 62.9%-93.0%) of LBC or the combination of sPAX1 m/JAM3 m and LBC low-grade and higher squamous intraepithelial lesion testing [87.0% (95% CI 67.9%-95.5%)]. Conclusions:Self-collected specimens by women for detection of PAX1 and JAM3 methylation as a promising screening tool for cervical cancer has operational and clinical feasibility. The methylation test can optimize the current cervical cancer screening plan, reduce the number of referral women with false positive diagnosis to colposcopy, and is of great significance for reducing fertility protection and preventing missed diagnosis in women of childbearing age.

Objective:To explore the efficacy and safety of cryopreservation-free integrated autologous hematopoietic stem cell transplantation (HSCT) model for patients with multiple myeloma.Methods:A total of 96 patients with newly diagnosed multiple myeloma (NDMM) between July 31, 2020, and December 31, 2022, were retrospectively analyzed, of which 41 patients in the observation group received integrated non-cryopreserved transplantation mode. After hematopoietic stem cells were mobilized and collected, melphalan was started immediately for pre-transplant conditioning, and non-cryopreserved grafts from the medical blood transfusion refrigerator were directly injected intravenously into the patient within 24-48 h after the melphalan conditioning. The control group consisted of 55 patients who received traditional transplantation mode. After hematopoietic stem cells were collected, stem cell cryopreservation was performed in liquid nitrogen, and then the transplant plans were started at the right time. All patients received mobilization of autologous hematopoietic stem cells using the G-CSF combined with the plerixafor.Results:① A total of 34 patients (82.9% ) with VGPR plus CR in the observation group were significantly higher than 33 patients (60.0% ) in the control group ( P=0.016). ②Compared with the control group, the incidence of grade 1 oral mucosal inflammation was higher in the observation group ( P<0.001) ; however, the incidence of grades 2 and 3 oral mucosal inflammation was lower ( P=0.004, P=0.048), and neither group experienced grade 4 or above oral mucosal inflammation. The incidence of grade 1 diarrhea was higher in the observation group ( P=0.002), whereas the incidence of grade 3 diarrhea was lower ( P=0.007). No statistically significant difference was observed in the incidence of grade 4 diarrhea ( P=0.506), and neither group experienced grade 5 diarrhea. ③ The incidence of bacterial infection in the observation group was lower than that in the control group (34.1% vs 65.5%, P=0.002), whereas no statistically significant difference was observed in the incidence of fungal infection (29.3% vs 31.4%, P=0.863) and viral infection (4.88% vs 3.64%, P=0.831). ④No statistically significant difference was observed in the implantation time of granulocytes and platelets between the observation and control groups [10 (8-20) days vs 11 (8-17) days, P=0.501; 13 (10-21) days vs 15 (10-20) days, P=0.245]. ⑤ All patients did not receive lenalidomide treatment 100 days post-transplantation. At 30 days post-transplantation, the CTL, NK, and Th cell counts in the observation group were lower than those in the control group ( P<0.001, P=0.002, P=0.049), and the NKT cell counts were higher than those in the control group ( P=0.024). At 100 days post-transplantation, the CTL, NKT, and Th cell counts in the observation group were higher than those in the control group ( P=0.025, P=0.011, P=0.007), and no statistically significant difference in NK cell counts was observed between the two groups ( P=0.396). ⑥ The median follow-up was 18 (4-33) months. The overall 2-year survival rates of the observation and control groups post-transplantation were 91.5% and 78.2%, respectively ( P=0.337). The recurrence-free survival rates were 85.3% and 77.6%, respectively ( P=0.386), and the cumulative recurrence rates were 9.8% and 16.9%, respectively ( P=0.373) . Conclusion:In NDMM, the cryopreservation-free integrated autologous HSCT model can achieve similar therapeutic effects as traditional transplantation models, with lower rates of severe mucosal inflammation and infection compared with traditional transplantation models.

We conducted a prospective study to assess the non-inferiority of adjuvant chemotherapy alone versus adjuvant concurrent chemoradiotherapy (CCRT) as an alternative strategy for patients with early-stage (FIGO 2009 stage IB-IIA) cervical cancer having risk factors after surgery. The condition was assessed in terms of prognosis, adverse effects, and quality of life. This randomized trial involved nine centers across China. Eligible patients were randomized to receive adjuvant chemotherapy or CCRT after surgery. The primary end-point was progression-free survival (PFS). From December 2012 to December 2014, 337 patients were subjected to randomization. Final analysis included 329 patients, including 165 in the adjuvant chemotherapy group and 164 in the adjuvant CCRT group. The median follow-up was 72.1 months. The three-year PFS rates were both 91.9%, and the five-year OS was 90.6% versus 90.0% in adjuvant chemotherapy and CCRT groups, respectively. No significant differences were observed in the PFS or OS between groups. The adjusted HR for PFS was 0.854 (95% confidence interval 0.415-1.757; P = 0.667) favoring adjuvant chemotherapy, excluding the predefined non-inferiority boundary of 1.9. The chemotherapy group showed a tendency toward good quality of life. In comparison with post-operative adjuvant CCRT, adjuvant chemotherapy treatment showed non-inferior efficacy in patients with early-stage cervical cancer having pathological risk factors. Adjuvant chemotherapy alone is a favorable alternative post-operative treatment.

Perfluoroalkyl and polyfluoroalkyl substances (PFASs), as a group of persistent organic pollutants among environmental endocrine disruptors, are widely used in industrial production and daily life. PFASs are widely and persistently present in the environment and organisms due to their bioaccumulation, long half-life, and low degradability properties. Published studies have proved that PFASs have immunotoxicity, endocrine toxicity, neurotoxicity, reproductive toxicity, and hepatotoxicity. At present, several epidemiological studies have been conducted on the effects of PFASs on allergic diseases, the research endpoints include asthma, allergic rhinitis, atopic dermatitis, and the expression of allergic biomarkers such as serum immunoglobulin E (IgE), but no consistent results have been observed yet. PFASs have the potential to activate several signaling pathways, including the peroxisome proliferator-activated receptor (PPAR), nuclear factor-κB (NF-κB), and JAK/STAT pathways. These mechanisms, along with increasing mast cell calcium influx and sex hormone synergistic effects, may contribute to immunomodulation in allergic diseases. At present, the exact human effect of PFASs exposure on allergic diseases and the related mechanisms are still uncertain. This review focused on the impacts of PFASs on asthma, allergic rhinitis, and atopic dermatitis and their possible mechanisms, so as to provide research ideas for the prevention, diagnosis, and treatment of allergic diseases.

Objective:
To explore the effect of 18β-sodium glycyrrhetinic acid on thymic stromal lymphopoietin (TSLP) in nasal mucosa of allergic rhinitis (AR) rats.
Methods:
One hundred Wistar rats,half male and half female,were randomly divided into 5 groups by random number table method: control group, AR model group,budesonide group,18β-sodium glycyrrhetinic acid at dose of 20 mg/kg and 40 mg/kg groups, with 20 rats in each group. AR animal models were established by ovalbumin (OVA) sensitization in the other four experimental groups. After successful modeling, budesonide and 18β-sodium glycyrrhetinic acid were given in each group,and the detection time points were 2 weeks and 4 weeks. The distribution of TSLP in rat nasal mucosa was detected by immunohistochemistry,and the expression of TSLP in rat nasal mucosa was determined by Western blot at the protein level. The expression of TSLP-mRNA in rat nasal mucosa was detected and compared by real-time fluorescence quantitative PCR (RT-PCR) at mRNA level. The concentrations of IL-4 and OVA-sIgE in rat serum were measured and compared by ELISA. One-way analysis of variance and the least significant difference method were used for the comparison among groups, LSD
