Objective: To analyze the timeliness of antir-etroviral therapy (ART) and its influencing factors among newly reported HIV/AIDS cases in Wenzhou City, Zhejiang Province from 2016 to 2023, so as to provide a reference for improving the ART effect of HIV/AIDS cases. Methods: Newly reported HIV/AIDS cases in Wenzhou City from 2016 to 2023 were selected as the research subjects. Demographic information, the situation of the first CD4+ T lymphocyte (CD4 cell) test, baseline CD4 cell count, and ART situation were collected through the Chinese Disease Prevention and Control Information System. The timely rate of ART was analyzed, and the influencing factors for timely ART among HIV/AIDS cases were analyzed using a multivariable logistic regression model. Results: A total of 4 500 newly reported HIV/AIDS cases in Wenzhou City from 2016 to 2023 were included, among which 3 679 were males, accounting for 81.76%, and 821 were females, accounting for 18.24%. The median age was 46.24 (interquartile range, 26.23) years. Among these cases, 3 606 received timely ART, with a timely rate of 80.13%. The timely rate of ART increased from 57.54% in 2016 to 91.97% in 2023 (P<0.05). Multivariable logistic regression analysis showed that unmarried/divorced/widowed (OR=0.769, 95%CI: 0.641-0.922), detainees (OR=0.492, 95%CI: 0.269-0.900), untimely first CD4 cell test (OR=0.278, 95%CI: 0.234-0.330), baseline CD4 cell count ≥200 cells/µL (OR=0.709, 95%CI: 0.595-0.843) or undetected (OR=0.131, 95%CI: 0.080-0.213) were associated with a lower timeliness for ART among HIV/AIDS cases. Conclusion From 2016 to 2023, the timely rate of ART among newly reported HIV/AIDS cases in Wenzhou City showed an upward trend, which was mainly affected by marital status, case source, timeliness of the first CD4 cell test, and baseline CD4 cell count.

Objective To compare H_p(3) calibration with a homemade (A) thermoluminescent dosimeter (TLD) and an imported (B) TLD in a standard X-ray RQR radiation field, to explore the different responses of A and B, and to provide foundation for the calibration of H_p(3). Methods A column mode was selected. H_p(3) calibration was performed using A and B in a standard X-ray RQR radiation field in the Secondary Standard Dosimetry Laboratory, National Institute for Radiological Protection, China Center for Disease Control and Prevention. Angle response, energy response, and linear response were calibrated with RQR4 (60 kV), RQR7 (90 kV), and RQR9 (120 kV), respectively. Results In terms of angle response, the calibration results of A were relatively high, while the calibration results of B were relatively low. In terms of energy response, the calibration results showed a similar pattern to angle response. In terms of linear response, the calibration results of both A and B were satisfactory. Conclusion Both A and B can be used for normal calibration of H_p(3) in a standard X-ray RQR radiation field. However, in actual monitoring, attention should be paid to the energy and angle response values of TLDs.

Objective:To investigate the clinical phenotype and genetic characteristics of patients with Fabry disease caused by a GLA variant, IVS4+919G>A.Methods:It was a prospective study. Fabry disease screening was conducted among high-risk population in Ninghai from October 2021 to August 2023. Those children with decreased α-galactosidase enzyme activity<2.40 μmol/(L·h) or elavated Lyso-GL-3 level>1.10 μg/L in dried blood spot (DBS) method underwent GLA genetic testing for diagnosis confirmation. Meanwhile, family screening was carried out. A proband and his family members diagnosed with Fabry disease were research subjects. The clinical and genetic characteristics of patients with Fabry disease caused by the GLA variant (IVS4+919G>A) were analyzed.Results:The female proband aged 9.8 years with pain in both lower limbs as the initial symptom was found to have a heterozygous GLA variant IVS4+919G>A among 102 patients. In family screening, there were 4 family members (proband's father, elder sister, elder male cousin and elder female cousin) with Fabry disease and a family member (proband's fifth aunt) with a GLA variant. Among these 4 diagnosed family members, the elder male cousin of the proband, a boy aged 13.2 years had a heterozygous GLA variant, IVS4+919G>A with intermittent pain in both lower limbs as the initial symptom. The proband′s father had knee joint pain. The proband′s elder sister had decreased vision and his elder female cousin had no obvious symptoms. The proband′s fifth aunt with a GLA variant had decreased vision.Conclusions:High-risk screening in children and family screening are helpful for early diagnosis and treatment of Fabry disease. Neuropathic pain may be a early symptom in children with Fabry disease caused by the GLA variant, IVS4+919G>A.

Objective:To compare the clinical value of digital breast tomosynthesis (DBT) localization and stereotactic positioning biopsy of breast lesions.Methods:This study was a cross-sectional study. Totally of 250 patients who underwent breast biopsy at Shenzhen People′s Hospital, Luohu District People′s Hospital and Peking University Shenzhen Hospital between August 2021 to October 2023 was analyzed retrospectively, including 136 cases of DBT-guided biopsy (DBT-guided group) and 114 cases of stereotactic-guided biopsy (stereotactic-guided group). The stereotactic-guided biopsy methods included core needle biopsy (CNB) and wire positioning. The DBT-guided biopsy methods included CNB, wire positioning and vacuum-assisted breast biopsy (VABB). The χ2 test or Mann-Whitney U test was used to compare the puncture success rate, operation time, localization time, puncture time, number of first valid localization phases obtained, number of exposures, and complications of different biopsy methods between 2 groups. Results:In the wire positioning biopy, the puncture success rate was 100% (33/33) in DBT-guided group and 96% (48/50) in the stereotactic-guided group, with no statistically significant difference between the two groups ( P=0.515). Compared to the stereotactic-guided group, the operation time and localization time were shorter, and the number of first valid localization phases obtained, number of exposures were fewer in the DBT-guided group( P<0.05). The incidence of complications was lower in both the DBT-guided group and the stereotactic-guided group, with no statistically significant difference ( P=0.871). In CNB, both the DBT-guided group and the stereotactic-guided group had higher puncture success rates, with no statistically significant difference ( P=0.080). Compared to the stereotactic-guided group, the operation time, localization time and puncture time were shorter, and the number of first valid localization phases obtained, number of exposures were lower in the DBT-guided group, and the difference between the two groups were statistically significant ( P<0.05). The incidence of complications was lower in both the DBT-guided group and the stereotactic-guided group, with no statistically significant difference ( P=0.627). Twenty-one cases received DBT-guided VABB, with an operation time of (19.90±3.38) min, a localization time of 6.00 (6.00, 7.00) min, a puncture time of (13.42±3.28) min, the number of first effective localization phases obtained was 1.00 (1.00, 1.00) time, the number of exposures was 4.00 (3.50, 5.00) times, and one case experienced severe pain after puncture. Conclusion:Compared with stereotactic-guided biopsy, DBT-guided biopsy can reduce operation time and exposure times, and can target more types of breast lesions, with higher clinical application value.

PD-1 and PD-L1 antibodies have brought about extraordinary clinical benefits for cancer patients, and their indications are expanding incessantly. Currently, most PD-1/PD-L1 agents are administered intravenously, which may be uncomfortable for some cancer patients. Herein, we develop a novel oral-delivered small molecular, YPD-29B, which specifically targets human PD-L1. Our data suggested that YPD-29B could potently and selectively block the interaction between PD-L1 and PD-1, but did not inhibit any other immune checkpoints. Mechanistically, YPD-29B induced human PD-L1 dimerization and internalization, which subsequently activated T lymphocytes and therefore overcomes immunity tolerance in vitro. YDP-29B was modified as the YPD-30 prodrug to improve druggability. Using humanized mice with human PD-1 xenografts of human PD-L1 knock-in mouse MC38 cancer cells, we demonstrated that YPD-30 exhibited significant antitumor activity and was well tolerated in vivo. Taken together, our results indicate that YPD-30 serves as a promising therapeutic candidate for anti-human PD-L1 cancer immunotherapy.

Active exploration for building a model of medical alliances fitting local needs, proves imperative for the functional positioning of medical institutions, promoting inter-institutional cooperation and enhancing the capacity of primary medical services. The authors described experiences and insights of the No.1 Affiliated Hospital and the People′s government of Quangang District in their partnership, and building a brand new model of medical alliance between a hospital and a local government. Also presented are characteristics of such a model, and analysis of operational data in benefiting the people. They held that such a partnership is a worthy attempt in the healthcare reform, by means of building medical alliances between local government and provincial hospitals. Such a practice can provide valuable references for promoting government-hospital synergy, elevating primary healthcare capacity and advancing the hierarchical medical system.
