BACKGROUND: Generalized pustular psoriasis (GPP), a rare and recurrent autoinflammatory disease, imposes a substantial burden on patients and society. Awareness of GPP in China remains limited. METHODS: This cross-sectional survey, conducted between September 2021 and May 2023 across 14 hospitals in China, included GPP patients of all ages and disease phases. Data collected encompassed demographics, clinical characteristics, economic impact, disease severity, quality of life, and treatment-related complications. Risk factors for GPP recurrence were analyzed. RESULTS: Among 127 patients (female/male ratio = 1.35:1), the mean age of disease onset was 25 years (1st quartile [Q1]-3rd quartile [Q3]: 11-44 years); 29.2% had experienced GPP for more than 10 years. Recurrence occurred in 75.6% of patients, and nearly half reported no identifiable triggers. Younger age at disease onset ( P  = 0.021) and transitioning to plaque psoriasis ( P  = 0.022) were associated with higher recurrence rates. The median diagnostic delay was 8 months (Q1-Q3: 2-41 months), and 32.3% of patients reported misdiagnoses. Comorbidities were present in 53.5% of patients, whereas 51.1% experienced systemic complications during treatment. Depression and anxiety affected 84.5% and 95.6% of patients, respectively. During GPP flares, the median Dermatology Life Quality Index score was 19.0 (Q1-Q3: 13.0-23.5). This score showed significant differences between patients with and without systemic symptoms; it demonstrated correlations with both depression and anxiety scores. Treatment costs caused financial hardship in 55.9% of patients, underscoring the burden associated with GPP. CONCLUSIONS The substantial disease and economic burdens among Chinese GPP patients warrant increased attention. Patients with early onset disease and those transitioning to plaque psoriasis require targeted interventions to mitigate the high recurrence risk.

Objective To analyze the external radiation dose rate and radiation protection measures during treatment of a patient with hepatocellular carcinoma (HCC) who underwent ⁹⁰Y selective internal radiotherapy (⁹⁰Y-SIRT). Methods A male HCC patient who received ⁹⁰Y-SIRT with an activity of 4.65×10⁹ Bq was selected as the research subject using retrospective analysis. External radiation dose rate meters were used to detect ambient dose equivalent rates around the radiation worker, the HCC patient, and the workplace during treatment. Surface contamination meters were used to detect surface contamination levels of the radiation worker and the workplace. Results The ambient dose equivalent rate around the interventional radiology staff during treatment ranged from 3.7 to 39.0 μSv/h. The patient's ambient dose equivalent rate of surgical site at distances of 30, 100, and 200 cm ranged from 45.0 to 5.6, 4.4 to 0.4, and 0.4 to 0.1 μSv/h respectively without protection, and 14.0 to 3.4, 3.2 to 0.3, and 0.4 to 0.1 μSv/h respectively when the surgical site was covered with a 1.0 mmPb lead rubber drape after 0.0 to 161.0 hours of the surgery. In the nuclear medicine department, ambient dose equivalent rate of the workplace ranged from 0.4 to 740.0 μSv/h. The ambient dose equivalent rate around all monitoring points in the digital subtraction angiography operating room accounted at 0.1 μSv/h, and the observation ward ranged from 0.1 to 0.2 μSv/h. The β surface contamination levels of the radiation worker and workplace were below the minimum detection limit (0.16 Bq/cm²). Conclusion Radiation doses for both HCC patients and radiation worker remained within acceptable limits when appropriate protective equipment was used. A well-designed workplace layout is essential to ensure effective implementation of radiation protection.

Objective:To investigate the value of diffusion kurtosis imaging (DKI) and 18F-prostate specific membrane antigen (PSMA)-1007 in the differential diagnosis of prostate cancer (PCa) and benign prostatic hyperplasia (BPH) by using PET/MR imaging. Methods:From June 2019 to December 2022, a retrospective analysis was conducted on 134 patients ((65.5±10.0) years) with prostate diseases who underwent 18F-PSMA-1007 PET/MR whole-body examination at Ruijin Hospital, Shanghai Jiao Tong University School of Medicine, with the prostate specific antigen (PSA) level continuously rising to >4μg/L within 1 month and not yet receiving treatment. Patients were divided into 2 groups (PSA<10μg/L and PSA≥10μg/L). The PET/MR examination included high b-value diffusion imaging, and the ROI was delineated based on the prostate diffusion weighted imaging (DWI) high-signal area and apparent diffusion coefficient (ADC) low-signal area by the professional radiology physician. The SUV max, mean kurtosis (MK), and mean diffusivity (MD) were obtained. Spearman rank correlation analysis was performed, and ROC curve was used to analyze the diagnostic efficacy. Results:Of 134 patients, 72 were with PSA<10μg/L and 62 were with PSA≥10μg/L. There were 68 patients who obtained biopsy results, including 37 cases of BPH and 31 cases of PCa. In PSA<10μg/L group, there were no significant correlations between MK and SUV max, MK and PSA ( rs values: 0.22, 0.06, P values: 0.065, 0.603). In the PSA≥10μg/L group, there were positive correlations between MK and SUV max, MK and PSA ( rs values: 0.52, 0.40, P values: 0.008, 0.005). In the PSA<10μg/L group, SUV max, MK, and MD showed no diagnostic value (AUCs: 0.44-0.67, all P>0.05), while the AUC for combined diagnosis using these three parameters was 0.78( P=0.008). In the PSA≥10μg/L group, the AUCs of SUV max, MK, and MD were 0.81( P=0.001), 0.84( P<0.001) and 0.72( P=0.023) respectively, and the AUC for combined diagnosis using these three parameters was 0.91( P<0.001). Conclusion:The combination of MK, MD and SUV max improves the diagnostic efficacy of PCa in PET/MR examination.

Objective:To examine the near-complete genomic analysis of norovirus (NoV) subtype GⅡ.17 [P17] outbreaks in Beijing Chaoyang District from 2014 to 2024.Methods:Data and specimens related to outbreaks of the NoV aggregation in Beijing′s Chaoyang District from 2014 to 2024 were collected. The NoV was identified using real-time fluorescence reverse transcription polymerase chain reaction (RT-PCR). Specimens with positive nucleic acid were amplified by standard PCR, whole genome sequencing and evolutionary analysis. Amino acid site variations were compared.Results:In Chaoyang District, from 2014 to 2024, a total of 637 aggregated outbreaks caused by the NoV infection were reported, of which 584 were successfully typed. The epidemic caused by the GⅡ.17 [P17] subtype accounted for 8.79% (56/637), which was the dominant epidemic gene subtype in 2014-2015, sporadic in 2016-2019, reappeared in 2022, and significantly increased in 2024 (27.27%, 24/88). Outbreaks caused by the GⅡ.17 [P17] subtype occurred mainly from October to December, with the main sites of occurrence in primary schools and kindergartens. This study yielded 53 near-complete genome sequences of the GⅡ.17 [P17] subtype from 46 incidents in Chaoyang District. The GⅡ.17 [P17] subtype sequences of Chaoyang District from 2014 to 2024 were segmented into three subgroups on the evolutionary tree, with sequences from 2014 to 2019, 2022 to April 2024, and May to December 2024 clustered into the d, e, and b subgroups, respectively. In the VP1 region′s P2 area, particularly at the HBGA binding site, subgroups b and e exhibited mutations in 22 and two sites, while subgroups b and e showed mutations in four and one sites, predominantly in the RdRp region.Conclusion:The outbreak caused by the NoV GⅡ.17 [P17] subtype in Chaoyang District from 2014 to 2024 continues, with a significant increase in 2024, and it becomes the dominant gene subtype from October to December. The sequence formation of the NoV GⅡ.17 [P17] subtype in Chaoyang District from January to April 2022 and from May to December 2024 shows two different evolutions, with specific mutation sites, requiring continuous monitoring of the NoV GⅡ.17 [P17] subtype.

Objective:To elucidate the genomic characteristics of the immunoglobulin (IG) heavy-chain variable region and light-chain variable region, the expression of subclones, and the prognostic significance in patients with CLL.Methods:Blood and/or bone marrow specimens were gathered from a cohort of 36 patients with CLL diagnosed at Jiangsu Province Hospital from December 2018 to May 2023, including 12 cases of B cell receptor (BCR) stereotyped patients. IG heavy-chain (IGH) and light-chain (IG Kappa [IGK] and IG lambda [IGL]) gene rearrangements were performed using next-generation sequencing (NGS) technology to analyze the characteristics and prognostic value in CLL.Results:NGS detection of IG variable region (IGHV) demonstrated a significant correlation and superior consistency with Sanger sequencing ( r=0.957, P < 0.001). Among the 36 patients, the IGH variant (IGHV) was observed in 9 (25.0%) but not in 27 (75.0%) participants. The incidence of the MYD88 mutation was higher among patients with mutated IGHV [1/27 (3.7%) vs 4/9 (44.4%), P=0.00]. A high incidence of trisomy 12 was observed in the IGHV #8/#8B subset [4/11 (36.4%) vs 1/25 (4.0%), P=0.023], which were more likely to develop Richter transformation [8/11 (72.7%) vs 4/25 (16.0%), P=0.002]. In the patient cohort, 36 individuals (36/36, 100.0%) used the IGK variable, whereas 15 individuals (15/36, 41.7%) employed the IGL variable (IGLV). IGLV3 - 21 reported the highest utilization rate in IGLV (5/15, 33.3%). Remarkably, patients with CLL with IGLV3-21 fragments were exclusively observed in the Binet C stage and Rai Phase Ⅲ-Ⅳ, with an incidence of del (13) (q14) at 60.0% (3/5). The median time to first treatment (TTFT) of patients with or without IGLV3 - 21 fragments was 5.2 (1.1 - 41.5) and 9.9 (0.1 - 94.4) months, respectively. Using the total reads threshold of 2.5%, 4 (4/36, 11.1%) samples were detected to have two IGHV productive clones. The median TTFT and overall survival (OS) time were 2.8 (0.9-72.7) and 12.8 months in patients with one mutated clone and 57.5 (32.0-120.7) and 51.8 months in those with two mutated clones, respectively. The median TTFT and OS time were 10.9 (0.3-94.4) and 6.3 (0.1 - 12.5) months in patients with one unmutated clone and 49.9 (22.2 - 211.1) and 30.0 (9.6 - 50.3) months in those with multiple unmutated clones, respectively ( P>0.05) . Conclusions:Detection of IG gene rearrangements using NGS technology not only facilitates the analysis of the IGHV mutation status, dominant clones, and prognostic value but also contributes to the exploration of IGK/IGL gene rearrangement fragments and the utilization of subclones. Further, it provides information about the poor prognosis of IGLV3 - 21 CLL. The shortened survival of the two unmutated clone groups in the IGHV unmutated group may indicate a poor prognosis.

Objective:To investigate the clinical effect of indocyanine green angiography (ICGA)-assisted design and harvest of expanded flaps for scar reconstruction.Methods:This study was a retrospective observational study. From April 2019 to August 2023, 19 patients with scars (8 males, 11 females; aged 3-38 years) treated at the Plastic Surgery Hospital of Peking Union Medical College and Chinese Academy of Medical Sciences met the inclusion criteria. The scars were distributed on the head, face, trunk, and extremities. In stage Ⅰ surgery, skin soft tissue expanders were implanted in suitable areas around the scars for skin soft tissue expansion. In stage Ⅱ surgery, the scar tissue was excised, resulting in wound areas ranging from 100 to 210 cm 2, and expanded flaps were designed. ICGA was used to identify target perforators and their accompanying veins, and the flap design was adjusted to ensure the inclusion of complete arterial and venous axes. The expanded flap with an area of 120 to 240 cm2 was harvested using unilateral back-cut technique and transferred to the recipient site, and the donor site wound was sutured directly. The durations of the arterial and venous phases of ICGA during flap design were recorded. The length-to-width ratios of the back-cut flaps were calculated for different regions. After stage Ⅱ surgery, the blood perfusion and survival of the flap, the wound healing at the donor site, and the occurrence of complications were observed. During follow-up, the appearance, color, and texture of the patient's flap were observed. Results:The arterial phase of ICGA lasted 10-27 (18±5) s, and the venous phase lasted 78-116 (100±10) s. The length-to-width ratios of the back-cut flaps were 1.22±0.32, 1.63±0.12, and 1.15±0.21 for the head and neck, trunk, and limb regions, respectively. After stage Ⅱ surgery, one patient had a large area of insufficient blood perfusion in the flap. By comparing ICGA images before and after flap transfer, the sutures at the oral commissure were loosened, the blood flow of the flap was restored. The blood perfusion of the flaps in other patients was good. All flaps survived completely, with well-healed donor site wounds and no complications. During 0.5-14.0 months of follow-up, all flaps of patients demonstrated excellent appearance, with color and texture matching the surrounding skin.Conclusions:As a means of superficial blood flow visualization, ICGA can not only clearly show the microvascular distribution of the expanded flap before operation, assist in optimizing the design of the flap, but also evaluate the blood perfusion of the flap after operation, reduce the occurrence of complications, and provide a full-process navigation for the harvesting of expanded flaps, thereby improving the safety of flap transfer for scar reconstruction.

Objective To investigate the distribution and antimicrobial resistance profiles of clinically isolated Haemophilus influenzae and Moraxella catarrhalis in hospitals across China from 2015 to 2021,and provide evidence for rational use of antimicrobial agents.Methods Data of H.influenzae and M.catarrhalis strains isolated from 2015 to 2021 in CHINET program were collected for analysis,and antimicrobial susceptibility testing was performed by disc diffusion method or automated systems according to the uniform protocol of CHINET.The results were interpreted according to the CLSI breakpoints in 2022.Beta-lactamases was detected by using nitrocefin disk.Results From 2015 to 2021,a total of 43 642 strains of Haemophilus species were isolated,accounting for 2.91％of the total clinical isolates and 4.07％of Gram-negative bacteria in CHINET program.Among the 40 437 strains of H.influenzae,66.89％were isolated from children and 33.11％were isolated from adults.More than 90％of the H.influenzae strains were isolated from respiratory tract specimens.The prevalence of β-lactamase was 53.79％in H.influenzae strains.The H.influenzae strains isolated from children showed higher resistance rate than the strains isolated from adults.Overall,779 strains of H.influenzae did not produce β-lactamase but were resistant to ampicillin(BLNAR).Beta-lactamase-producing strains showed significantly higher resistance rates to these antimicrobial agents than the β-lactamase-nonproducing strains.Of the 16 191 M.catarrhalis strains,80.06％were isolated from children and 19.94％isolated from adults.M.catarrhalis strains were mostly susceptible to both amoxicillin-clavulanic acid and cefuroxime,evidenced by resistance rate lower than 2.0％.Conclusions The emergence of antibiotic-resistant H.influenzae due to β-lactamase production poses a challenge for clinical anti-infective treatment.Therefore,it is very important to implement antibiotic resistance surveillance for H.influenzae and guide rational antibiotic use.All local clinical microbiology laboratories should actively improve antibiotic susceptibility testing and strengthen antibiotic resistance surveillance for H.influenzae.

Objective:To investigate the alterations in voxel-mirrored homotopic connectivity (VMHC) of brain regions, association loop connectivity, and white matter microstructure in patients with white matter hyperintensities (WMH) of presumed vascular origin, and analyze the pathological basis of cognitive impairment in WMH patients.Methods:A prospective study was performed; 75 WMH patients (WMH group) admitted to Jiangsu Shengze Hospital Affiliated to Nanjing Medical University from January 2023 to September 2024 and 67 volunteers without obvious brain diseases (control group) recruited during the same period were enrolled. General data of these participants, and scores of neuropsychological scales such as mini-mental state examination (MMSE), frontal assessment battery (FAB), and trail making test (TMT) were compared between the two groups. Resting-state functional magnetic resonance imaging (rs-fMRI) and diffusion tensor imaging (DTI) data of all participants were collected; rs-fMRI data were then analyzed using VMHC algorithm to calculate and conform the brain regions with significantly different VMHC between the two groups, and these regions were used as seed points to perform functional connectivity with the whole brain; Pearson correlation analyses of VMHC and functional connectivity in these brain regions with scores of neuropsychological scales were performed. DTI data were processed using tract-based spatial statistics (TBSS) method to calculate and conform the brain regions with significantly different diffusion parameters of fiber tracts between the two groups; Pearson correlation analyses of diffusion parameters of the fiber tracts in these brain regions with scores of neuropsychological scales were performed.Results:(1) Comparison of general data and neuropsychological scale scores: proportion of participants with hypertension history was significantly different between the two groups ( P<0.05); scores of TMT-A, TMT-B, and Stroop C scales in the WMH group were significantly higher than those in the control group ( P<0.05). (2) Comparison of VMHC and seed point functional connectivity: compared with that in the control group, the VMHC in bilateral middle occipital gyrus, visual cortex, medial occipitotemporal gyrus, insula, and postcentral gyrus of the WMH group were statistically lower ( P<0.05). Compared with that in the control group, functional connectivity of right visual cortex with right middle temporal gyrus, bilateral precuneus, and right dorsolateral superior frontal gyrus in the WMH group was significantly weakened, and functional connectivity of right postcentral gyrus with right medial occipitotemporal gyrus, left middle temporal gyrus, left visual cortex, and left postcentral gyrus was statistically weakened ( P<0.05). In the WMH group, the VMHC of bilateral insula was negatively correlated with TMT-B score ( r=-0.381, P<0.001), and functional connectivity between right visual cortex and right dorsolateral superior frontal gyrus was negatively correlated with Stroop C score ( r=-0.401, P<0.001). (3) TBSS results: the diffusion parameters of the anterior corona radiata, superior corona radiata, corpus callosum, superior longitudinal fasciculus, and posterior thalamic radiation were statistically significant between the two groups ( P<0.05). In the WMH group, the fractional anisotropy in the genu of the corpus callosum was positively correlated with Stroop C score ( r=0.426, P<0.001), radial diffusivity was negatively correlated with Stroop C score ( r=-0.376, P<0.001), and mean diffusivity of the left anterior corona radiata was negatively correlated with TMT-A score ( r=-0.443, P<0.001). Conclusion:WMH patients have decreased coordination in homotopic brain regions and weakened functional connectivity of association loops, with widely distributed white matter microstructure damages, which may be involved in the neuropathological process of cognitive impairment.

Salvia miltiorrhiza (Danshen) is a traditional Chinese herb that is commonly known for its cardiovascular and hepatoprotective benefits. Recent studies have confirmed that Danshen and its bioactive components can influence gut microbial homeostasis, thereby affecting Helicobacter pylori (HP) colonization in the human stomach. HP is a bacterial pathogen associated with various gastrointestinal diseases. Current HP treatments mainly involve antibiotics and proton pump inhibitors. However, their efficacy is strongly compromised by the rapid emergence of antibiotic resistance in HP and genetic heterogeneity among patients. The interaction between Danshen and gut microbial status provides a novel perspective for HP treatment. Understanding the medical properties of Danshen in altering gut microbiota and eliminating HP, as well as the underlying mechanisms, is important for improving human gastrointestinal healthcare. This review investigates the interaction between Danshen and gut microbiota and its impact on HP infection using databases including Web of Science, PubMed, and Google Scholar. We explored the unconventional intersection between Danshen, gut microbiota, and HP infection, shedding light on their intricate interplay and potential therapeutic implications. A comprehensive understanding of this interaction provides valuable insights into developing novel therapeutic strategies that target the gut microbiota to mitigate HP-associated gastrointestinal disorders.
