RESUMEN
Objective: To further improve the understanding of paroxysmal nocturnal hemoglobinuria (PNH), we retrospectively analyzed and summarized the clinical characteristics, treatment status, and survival status of patients with PNH in Zhejiang Province. Methods: This study included 289 patients with PNH who visited 20 hospitals in Zhejiang Province. Their clinical characteristics, comorbidity, laboratory test results, and medications were analyzed and summarized. Results: Among the 289 patients with PNH, 148 males and 141 females, with a median onset age of 45 (16-87) years and a peak onset age of 20-49 years (57.8% ). The median lactic dehydrogenase (LDH) level was 1 142 (604-1 925) U/L. Classified by type, 70.9% (166/234) were classical, 24.4% (57/234) were PNH/bone marrow failure (BMF), and 4.7% (11/234) were subclinical. The main clinical manifestations included fatigue or weakness (80.8%, 235/289), dizziness (73.4%, 212/289), darkened urine color (66.2%, 179/272), and jaundice (46.2%, 126/270). Common comorbidities were hemoglobinuria (58.7% ), renal dysfunction (17.6% ), and thrombosis (15.0% ). Moreover, 82.3% of the patients received glucocorticoid therapy, 70.9% required blood transfusion, 30.7% used immunosuppressive agents, 13.8% received anticoagulant therapy, and 6.3% received allogeneic hematopoietic stem cell transplantation. The 10-year overall survival (OS) rate was 84.4% (95% CI 78.0% -91.3% ) . Conclusion: Patients with PNH are more common in young and middle-aged people, with a similar incidence rate between men and women. Common clinical manifestations include fatigue, hemoglobinuria, jaundice, renal dysfunction, and recurrent thrombosis. The 10-year OS of this group is similar to reports from other centers in China.

Objective: This study investigated the efficacy and safety of denosumab (DENOS) versus zoledronic acid (ZOL) in the bone disease treatment of newly diagnosed multiple myeloma. Methods: The clinical data of 80 patients with myeloma bone disease (MBD) at the Fifth Medical Center of PLA General Hospital between March 1, 2021 and June 30, 2023 were retrospectively reviewed. Eighteen patients with severe renal impairment (SRI, endogenous creatinine clearance rate<30 ml/min) were treated with DENOS, and 62 non-SRI patients were divided into DENOS (30 patients) and ZOL group (32 patients) . Results: Hypocalcemia was observed in 26 (33%) patients, and 22 patients developed hypocalcemia during the first treatment course. The incidence of hypocalcemia in the non-SRI patients of DENOS group was higher than that in the ZOL group [20% (6/30) vs 13% (4/32), P=0.028]. The incidence of hypocalcemia in SRI was 89% (16/18). Multivariate logistic regression analysis revealed that endogenous creatinine clearance rate<30 ml/min was significantly associated with hypocalcemia after DENOS administration (P<0.001). After 1 month of antiresorptive (AR) drug application, the decrease in the serum ß-C-terminal cross-linked carboxy-telopeptide of collagen type I concentrations of SRI and non-SRI patients in the DENOS group were significantly higher than that in the ZOL group (68% vs 59% vs 27%, P<0.001). The increase in serum procollagen type â N-terminal propeptide concentrations of patients with or without SRI in the DENOS group were significantly higher than that in the ZOL group (34% vs 20% vs 11%, P<0.05). The level of intact parathyroid hormone in each group increased after AR drug treatment. None of the patients developed osteonecrosis of the jaw and renal adverse events, and no statistically significant differences in the overall response rate, complete remission and stringent complete remission rates were found among the groups (P>0.05), and the median PFS and OS time were not reached (P>0.05) . Conclusions: In the treatment of MBD, DENOS minimizes nephrotoxicity and has strong AR effect. Hypocalcemia is a common adverse event but is usually mild or moderate and manageable.

Objective: To explore the menopause status of patients with rheumatoid arthritis (RA) and clinical characteristics of perimenopausal RA patients. Methods: A cross-sectional study. Female RA patients were recruited retrospectively in the Sun Yat-Sen Memorial Hospital from August 2015 to August 2023. Clinical data were collected, including onset age, disease duration, RA disease activity indicators, functional assessment, and radiographic scores. According to menopausal status, the patients were categorized as pre-menopausal, perimenopausal and post-menopausal groups to explore their menopausal and clinical characteristics. Results: A total of 1 151 female patients were enrolled, with a mean age of (50.2±13.0) years. At enrollment, there were 470 (40.8%), 140 (12.2%) and 541 (47.0%) patients in pre-menopause, perimenopause and post-menopause status, respectively. The mean age of menopause was (49.0±4.2) years. Compared with pre-menopausal group, perimenopausal RA patients had higher disease activity indicators [clinical disease activity index (CDAI) 17 (6, 26) vs 10 (3, 19) ], higher levels of inflammation [erythrocyte sedimentation rate (ESR) 35 (21, 65) vs 26 (14, 44) mm/1h, C-reactive protein (CRP) 6.2 (3.2, 16.8) vs 3.3 (3.2, 13.6) mg/L], and a higher proportion of functional limitation [25.0%(35/140) vs 10.4%(49/470)] (all P<0.016 7); while there was no significant differences in disease activity[M(Q1, Q3)] [CDAI 17 (6, 26) vs 14 (6, 25)], levels of inflammation [ESR 35(21, 65) vs 42 (23, 72) mm/1h, CRP 6.2 (3.2, 16.8) vs 6.2 (3.3, 23.9) mg/L] and functional limitation [25.0%(35/140) vs 28.8%(156/541)] when compared with those in post-menopausal group (all P>0.016 7). In RA patients during the perimenopausal period, 49 cases (35.0%) developed RA during this period. Compared with patients with RA onset during reproductive age, patients with RA onset during the perimenopausal period had higher numbers of 28-joint tender joints [7 (2, 10) vs 4 (0, 8)], higher CDAI [20 (12, 29) vs 14 (4, 24)], and higher ESR [45 (25, 72) vs 32 (18, 56) mm/1h] (all P<0.05). Conclusion: Perimenopausal patients with RA have severe disease activity and functional limitation.

OBJECTIVE: To investigate the involvement of the high mobility group box protein B1 (HMGB1)-Toll-like receptor 2 (TLR2)/TLR4-nuclear factor κB (NF-κB) pathway in the intestinal mucosal injury induced by Cryptosporidium parvum infection, and to examine the effect of oxymatrine (OMT) on C. parvum infection in mice. METHODS: Forty SPF 4-week-old BALB/c mice were randomly divided into four groups, including the control group, infection group, glycyrrhizin (GA) group and OMT group. Each mouse was orally administered with 1 × 105 C. parvum oocysts one week in the infection, GA and OMT groups following dexamethasone-induced immunosuppression to model C. parvum intestinal infections in mice. Upon successful modeling, mice in the GA group were intraperitoneally injected with GA at a daily dose of 25.9 mL/kg for successive two weeks, and animals in the OMT group were orally administered OMT at a daily dose of 50 mg/kg for successive two weeks, while mice in the control group were given normal food and water. All mice were sacrificed two weeks post-treatment, and proximal jejunal tissues were sampled. The pathological changes of mouse intestinal mucosal specimens were observed using hematoxylin-eosin (HE) staining, and the mouse intestinal villous height, intestinal crypt depth and the ratio of intestinal villous height to intestinal crypt depth were measured. The occludin and zonula occludens protein 1 (ZO1) expression was determined in mouse intestinal epithelial cells using immunohistochemistry, and the relative expression of HMGB1, TLR2, TLR4, myeloid differentiation primary response gene 88 (MyD88) and NF-κB p65 mRNA was quantified in mouse jejunal tissues using quantitative real-time PCR (qPCR) assay. RESULTS: HE staining showed that the mouse intestinal villi were obviously atrophic, shortened, and detached, and the submucosal layer of the mouse intestine was edematous in the infection group as compared with the control group, while the mouse intestinal villi tended to be structurally intact and neatly arranged in the GA and OMT groups. There were significant differences among the four groups in terms of the mouse intestinal villous height (F = 6.207, P = 0.000 5), intestinal crypt depth (F = 6.903, P = 0.000 3) and the ratio of intestinal villous height to intestinal crypt depth (F = 37.190, P < 0.000 1). The mouse intestinal villous height was lower in the infection group than in the control group [(321.9 ± 41.1) µm vs. (399.5 ± 30.9) µm; t = 4.178, P < 0.01] and the GA group [(321.9 ± 41.1) µm vs. (383.7 ± 42.7) µm; t = 3.130, P < 0.01], and the mouse intestinal crypt depth was greater in the infection group [(185.0 ± 35.9) µm] than in the control group [(128.4 ± 23.6) µm] (t = 3.877, P < 0.01) and GA group [(143.3 ± 24.7) µm] (t = 2.710, P < 0.05). The mouse intestinal villous height was greater in the OMT group [(375.3 ± 22.9) µm] than in the infection group (t = 3.888, P < 0.01), and there was no significant difference in mouse intestinal villous height between the OMT group and the control group (t = 1.989, P > 0.05). The mouse intestinal crypt depth was significantly lower in the OMT group [(121.5 ± 27.3) µm] than in the infection group (t = 4.133, P < 0.01), and there was no significant difference in mouse intestinal crypt depth between the OMT group and the control group (t = 0.575, P > 0.05). The ratio of the mouse intestinal villous height to intestinal crypt depth was significantly lower in the infection group (1.8 ± 0.2) than in the control group (3.1 ± 0.3) (t = 10.540, P < 0.01) and the GA group (2.7 ± 0.3) (t = 7.370, P < 0.01), and the ratio of the mouse intestinal villous height to intestinal crypt depth was significantly higher in the OMT group (3.1 ± 0.2) than in the infection group (t = 15.020, P < 0.01); however, there was no significant difference in the ratio of the mouse intestinal villous height to intestinal crypt depth between the OMT group and the control group (t = 0.404, P > 0.05). Immunohistochemical staining showed significant differences among the four groups in terms of occludin (F = 28.031, P < 0.000 1) and ZO1 expression (F = 14.122, P < 0.000 1) in mouse intestinal epithelial cells. The proportion of positive occluding expression was significantly lower in mouse intestinal epithelial cells in the infection group than in the control group [(14.3 ± 4.5)% vs. (28.3 ± 0.5)%; t = 3.810, P < 0.01], and the proportions of positive occluding expression were significantly higher in mouse intestinal epithelial cells in the GA group [(30.3 ± 1.3)%] and OMT group [(25.8 ± 1.5)%] than in the infection group (t = 7.620 and 5.391, both P values < 0.01); however, there was no significant differences in the proportion of positive occluding expression in mouse intestinal epithelial cells between the GA or OMT groups and the control group (t = 1.791 and 2.033, both P values > 0.05). The proportion of positive ZO1 expression was significantly lower in mouse intestinal epithelial cells in the infection group than in the control group [(14.4 ± 1.8)% vs. (24.2 ± 2.8)%; t = 4.485, P < 0.01], and the proportions of positive ZO1 expression were significantly higher in mouse intestinal epithelial cells in the GA group [(24.1 ± 2.3)%] (t = 5.159, P < 0.01) and OMT group than in the infection group [(22.5 ± 1.9)%] (t = 4.441, P < 0.05); however, there were no significant differences in the proportion of positive ZO1 expression in mouse intestinal epithelial cells between the GA or OMT groups and the control group (t = 0.037 and 0.742, both P values > 0.05). qPCR assay showed significant differences among the four groups in terms of HMGB1 (F = 21.980, P < 0.000 1), TLR2 (F = 20.630, P < 0.000 1), TLR4 (F = 17.000, P = 0.000 6), MyD88 (F = 8.907, P = 0.000 5) and NF-κB p65 mRNA expression in mouse jejunal tissues (F = 8.889, P = 0.000 7). The relative expression of HMGB1 [(5.97 ± 1.07) vs. (1.05 ± 0.07); t = 6.482, P < 0.05] ãTLR2 [(5.92 ± 1.29) vs. (1.10 ± 0.14); t = 5.272, P < 0.05] ãTLR4 [(5.96 ± 1.50) vs. (1.02 ± 0.03); t = 4.644, P < 0.05] ãMyD88 [(3.00 ± 1.26) vs. (1.02 ± 0.05); t = 2.734, P < 0.05] and NF-κB p65 mRNA [(2.33 ± 0.72) vs. (1.04 ± 0.06); t = 2.665, P < 0.05] was all significantly higher in mouse jejunal tissues in the infection group than in the control group. A significant reduction was detected in the relative expression of HMGB1 (0.63 ± 0.01), TLR2 (0.42 ± 0.10), TLR4 (0.35 ± 0.07), MyD88 (0.70 ± 0.11) and NF-κB p65 mRNA (0.75 ± 0.01) in mouse jejunal tissues in the GA group relative to the control group (t = 8.629, 5.830, 11.500, 4.729 and 6.898, all P values < 0.05), and the relative expression of HMGB1, TLR2, TLR4, MyD88 and NF-κB p65 mRNA significantly reduced in mouse jejunal tissues in the GA group as compared to the infection group (t = 7.052, 6.035, 4.084, 3.165 and 3.274, all P values < 0.05). In addition, the relative expression of HMGB1 (1.14 ± 0.60), TLR2 (1.00 ± 0.24), TLR4 (1.14 ± 0.07), MyD88 (0.96 ± 0.25) and NF-κ B p65 mRNA (1.12 ± 0.17) was significantly lower in mouse jejunal tissues in the OMT group than in the infection group (t = 7.059, 5.320, 3.510, 3.466 and 3.273, all P values < 0.05); however, there were no significant differences between the OMT and control groups in terms of relative expression of HMGB1, TLR2, TLR4, MyD88 or NF-κB p65 mRNA in mouse jejunal tissues (t = 0.239, 0.518, 1.887, 0.427 and 0.641, all P values > 0.05). CONCLUSIONS: C. parvum infection causes intestinal inflammatory responses and destruction of intestinal mucosal barrier through up-regulating of the HMGB1-TLR2/TLR4-NF-κB pathway. OMT may suppress the intestinal inflammation and repair the intestinal mucosal barrier through inhibiting the activity of the HMGB1-TLR2/TLR4-NF-κB pathway.

OBJECTIVES: This study aimed to assess the burden of early-onset gastrointestinal (GI) cancers in China over three decades. STUDY DESIGN: A comprehensive analysis was performed using data from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019. METHODS: Data on early-onset GI cancers in 2020 and from 1990 to 2019 were extracted from GLOBOCAN 2020 database and GBD 2019, respectively. The average annual percent change (AAPC) was calculated to analyze the temporal trends using the Joinpoint Regression Program. The Bayesian age-period-cohort (BAPC) model was used to predict future trends up to 2030. RESULTS: In China, there were 185,980 incident cases and 119,116 deaths of early-onset GI cancer in 2020, with the highest incidence and mortality observed in liver cancer (new cases: 71,662; deaths: 62,412). The spectrum of early-onset GI cancers in China has transitioned over the last 30 years. The age-standardized rates of incidence, mortality, and disability-adjusted life years for colorectal and pancreatic cancers exhibited rapid increases (AAPC >0, P ≤ 0.001). The fastest-growing incidence rate was found in colorectal cancer (AAPC: 3.06, P < 0.001). Despite the decreases in liver, gastric, and esophageal cancers, these trends have been reversed or flattened in recent years. High body mass index was found to be the fastest-growing risk factor for early-onset GI cancers (estimated annual percentage change: 2.75-4.19, P < 0.05). Projection analyses showed an increasing trend in age-standardized incidence rates for almost all early-onset GI cancers during 2020-2030. CONCLUSIONS: The transitioning pattern of early-onset GI cancers in China emphasizes the urgency of addressing this public health challenge.
RESUMEN
Objective: To explore the efficacy of venetoclax-based induction regimen for children with newly diagnosed acute myeloid leukemia (AML). Methods: Children with newly diagnosed AML in Beijing Children's Hospital Affiliated to Capital Medical University and Baoding Hospital Affliliated to Capital Medical University from November 2019 and December 2023 were prospectively included. The patients were divided into DAH group (daunorubicin, cytarabine and homoharringtonine) and VAH group (venetoclax, cytarabine and homoharringtonine) according to induction regimen. The clinical data of the children were collected, the clinical characteristics and induced remission rate between the two groups were compared, and multivariate logistic regression was used to analyze the related factors affecting the induced remission rate. Results: A total of 135 patients were enrolled, including 96 cases in the DAH group (54 males and 42 females), aged [M (Q1, Q3)] 6.4 (3.9, 11.6) years and 39 cases in the VAH group (26 males and 13 females), aged 8.0 (6.2, 13.2) years. Among patients initially diagnosed with low-medium risk AML, the morphologic complete remission rates were 94.7% (18/19) in the VAH group and 84.4% (38/45) in the DAH group, respectively, and the negativity conversion rates of minirnal residual disease (MRD) were 57.9% (11/19) and 46.7% (21/45), respectively, with no statistically difference (all P>0.05). Among patients initially diagnoised with high-risk AML, the morphologic complete remission rates in the VAH group was higher than that in the DAH group [95.0% (19/20) vs 70.6% (36/51), P=0.027], and negativity conversion rates of MRD were 45.0% (9/20) and 33.3% (17/51), respectively, with no statistically difference (P=0.359). The induction regimen (venetoclax, cytarabine and homoharringtonin) was beneficial to morphological remission (OR=0.126, 95%CI: 0.025-0.629). FLT3 mutation was not conducive to morphological remission (OR=5.832, 95%CI: 1.778-19.124) and negative MRD (OR=4.166, 95%CI: 1.396-12.433). Conclusion: Venetoclax-based induction regimen is more effective than traditional chemotherapy regimen for newly diagnosed pediatric AML.

Objective: To investigate the association between sleep status and the risk for coronary heart disease in adults in Suzhou. Methods: Using the baseline and follow up information of 53 269 local residents aged 30-79 years in China Kadoorie Biobank conducted in Wuzhong District, Suzhou, 51 929 subjects were included in this study after excluding those reporting coronary heart disease, stroke and cancer at the baseline survey. A Cox proportional hazards regression model was used to analyze the association of healthy sleep score (0-3 points) and sleep factors (snoring, insomnia, long sleep duration and nap) with the risk for coronary heart disease. Results: The median follow-up time was 11.12 years, and 1 304 individuals were diagnosed with coronary heart disease during the follow-up. After adjusting for potential confounders, occasional snoring (HR=1.20, 95%CI: 1.04-1.38), usual snoring (HR=1.17, 95%CI: 1.02-1.33), insomnia disorder (HR=1.41, 95%CI: 1.12-1.78), daytime dysfunction (HR=1.56, 95%CI: 1.20-2.03) and perennial nap (HR=1.37, 95%CI: 1.19-1.59) were associated with increased risk of coronary heart disease. Compared with those with sleep score of 0 - 1 (low sleep quality), the people with sleep score of 3 had reduced risk of coronary heart disease by 26% (HR=0.74, 95%CI: 0.63-0.87). Stratified analysis showed that the association of healthy sleep score 3 with risk of coronary heart disease was stronger in low physically active individuals (interaction P<0.05). Conclusions: Snoring, insomnia disorders, daytime dysfunction, and perennial napping were all associated with increased risk for coronary heart disease, and keep healthy sleep mode might reduce the risk for coronary heart disease in adults.

OBJECTIVE: To investigate the epidemiological characteristics and mutation spectrum of monogenic diseases in Chinese population through a large-scale, multicenter carrier screening. METHODS: This study was conducted among a total of 33 104 participants (16 610 females) from 12 clinical centers across China.Carrier status for 223 genes was analyzed using high-throughput sequencing and different PCR methods. RESULTS: The overall combined carrier frequency was 55.58% for 197 autosomal genes and 1.84% for 26 X-linked genes in these participants.Among the 16 669 families, 874 at-risk couples (5.24%) were identified.Specifically, 584 couples (3.50%) were at risk for autosomal genes, 306(1.84%) for X-linked genes, and 16 for both autosomal and X-linked genes.The most frequently detected autosomal at-risk genes included GJB2(autosomal recessive deafness type 1A, 393 couples), HBA1/HBA2(α-thalassemia, 36 couples), PAH (phenylketonuria, 14 couples), and SMN1(spinal muscular atrophy, 14 couples).The most frequently detected X-linked at-risk genes were G6PD (G6PD deficiency, 236 couples), DMD (Duchenne muscular dystrophy, 23 couples), and FMR1(fragile X syndrome, 17 couples).After excluding GJB2 c.109G>A, the detection rate of at-risk couples was 3.91%(651/16 669), which was lowered to 1.72%(287/16 669) after further excluding G6PD.The theoretical incidence rate of severe monogenic birth defects was approximately 4.35(72.5/16 669).Screening for a battery of the top 22 most frequent genes in the at-risk couples could detect over 95% of at-risk couples, while screening for the top 54 genes further increased the detection rate to over 99%. CONCLUSION: This study reveals the carrier frequencies of 223 monogenic genetic disorders in the Chinese population and provides evidence for carrier screening strategy development and panel design tailored to the Chinese population.In carrier testing, genetic counseling for specific genes or gene variants can be challenging, and the couples need to be informed of these difficulties before testing and provided with options for not screening these genes or gene variants.

Objective: To determine the causal relationship between educational attainment and the risk of allergic rhinitis and (or) eczema using Mendelian randomization (MR) analyses. Methods: This study was a secondary data analysis based on the summary data of genome-wide association studies (GWAS), which involved 293 723 participants (educational attainment) from the Social Science Genetics Association Consortium and 462 013 participants [allergic rhinitis and (or) eczema] from the UK Biobank. Genetic variants that were closely related to educational attainment were identified as instrumental variables. Two-sample MR analyses, including inverse-variance weighted (IVW), MR-Egger regression, weighted median method and weighted model-based estimation, were performed to investigate the causal relationship between educational attainment and the risk of allergic rhinitis and (or) eczema, in which the odds ratio (OR) values were used as indicators. Results: A total of 70 single-nucleotide polymorphisms (SNPs) were chosen as instrumental variables. The MR-Egger regression results suggested that the genetic pleiotropy was unlikely to bias our results (P=0.107). In the univariable MR analyses, IVW regression showed that the risk of allergic rhinitis and (or) eczema was OR=1.044 (95%CI: 1.020-1.069, P<0.001) and OR=1.170 (95%CI: 1.074-1.256, P<0.001), respectively, for the increase in the duration of education by one year or one standard deviation (SD) (3.71 years). In the reverse MR analysis, IVW regression showed little evidence that allergic rhinitis and (or) eczema affected educational attainment (OR=1.020, 95%CI: 0.927-1.023, P=0.683). The results of the weighted median method and weighted mode-based estimation were consistent with the results of IVW. Conclusion: This study suggests that there is a positive causal relationship between educational attainment and the risk of allergic rhinitis and (or) eczema, which means that educational attainment can increase the occurrence of allergic rhinitis and (or) eczema.

Objective: To investigate the association of urinary cadmium levels with peripheral leukocyte classification counts among middle-aged and older adults aged 40 to 89 years in selected areas of China. Methods: The research was based on the survey of the impact of soil quality of agricultural land on human health in typical areas conducted in 2019-2020. A total of 5 600 middle-aged and older adults aged 40 to 89 years were included by using a multi-stage stratified random sampling method. Baseline characteristics of the subjects were collected and physical examinations were performed. Random midstream urine was collected to measure urinary cadmium and urinary creatinine and fasting venous blood was collected to measure the leukocyte count, neutrophil count, lymphocyte count, monocyte count and eosinophil count. The linear mixed effect model was used to analyse the association of urinary cadmium levels with leukocyte classification counts, and the dose-response relationship between them was analyzed by using the restricted cubic spline (RCS) function. Results: The age of the subjects was (63.17±12.02) years; 2 851 (50.91%) were males; and the M (Q1, Q3) of urinary creatinine-corrected urinary cadmium levels was 2.69 (1.52, 4.69) µg/g·creatinine. After adjusting for confounding factors, the results of linear mixed effects model analysis showed that for each 1-unit increase in urinary creatinine-corrected urinary cadmium level, the percentage change [% (95%CI)] of leukocyte count and lymphocyte count was -1.70% (-2.61%, -0.79%) and -1.57% (-2.86%, -0.26%), respectively. RCS function showed a negative linear relationship between urinary creatinine-corrected urinary cadmium levels and leukocyte counts and lymphocyte counts, respectively (all Pnon-linear>0.05). Conclusion: Urinary cadmium levels are negatively associated with leukocyte count and lymphocyte count among middle-aged and older adults aged 40 to 89 years in selected areas of China.

Pulmonary aspergillosis is a serious pulmonary fungal infectious disease. It is difficult to manage and has limited treatment options. Existing anti-aspergillus medications have high rates of treatment failure and increased drug resistance, making it difficult to meet the clinical requirements. Therefore, the development of new, effective treatment programs is critical. According to research, interferons play an important role in the body's immune response to bacterial and viral infectious diseases. Inadequate interferon expression or dysfunction can put the body at risk for certain infectious diseases. Interferon has been used in clinical trials to prevent or treat infectious diseases. In recent years, researchers have focused on the immunological role of interferon in Aspergillus infections and its potential for clinical application. This review summarized the most recent advances in the immunoregulatory mechanisms of interferon and its clinical application in Aspergillus infections.

Objective: To investigate the clinical features of acute macular neuroretinopathy (AMN) following coronavirus disease 2019 (COVID-19). Methods: This retrospective case series study included 15 patients (28 eyes) diagnosed with AMN at the Department of Ophthalmology, Peking University Third Hospital, from November 2022 to January 2023. The AMN group comprised 4 males and 11 females, with a mean age of (31.36±8.08) years. A control group of 15 individuals [5 males, 10 females; mean age (33.20±5.10) years] who had COVID-19 but did not develop AMN was also included. Data collected for all patients included best-corrected visual acuity (BCVA), slit-lamp examination, dilated fundus examination, color fundus photography, fluorescein fundus angiography (FFA), and optical coherence tomography (OCT) results. Serum cytokine levels, including interleukins (ILs), interferons (IFNs), and tumor necrosis factor-alpha (TNF-α), were measured for both groups. Results: Among the 28 eyes, severe vision loss (BCVA≤0.3) was observed in 3 eyes (10.7%), moderate vision loss (BCVA>0.3 and≤0.5) in 2 eyes (13.3%), and mild vision loss (BCVA>0.5 and≤1.0) in 23 eyes (82.1%). OCT findings in all 28 eyes revealed hyperreflectivity of the outer nuclear layer and disruption of outer retinal structure. Additionally, 3 eyes (10.7%) exhibited cotton wool spots in the posterior pole, 2 eyes (7.1%) showed mild cystoid macular edema with intraretinal hyperreflective dots, and 1 eye (3.6%) presented with paracentral acute middle maculopathy. FFA indicated retinal vasculitis in 2 cases (4 eyes, 14.3%). Serum levels of IL-4, IL-5, IFN-α, and IFN-γ were significantly higher in the AMN group compared to the control group: IL-4 [4.49 (3.66, 6.08) vs. 1.40 (0.62, 1.68) pg/ml], IL-5 [7.34 (5.04, 14.06) vs. 0.17 (0.11, 1.86) pg/ml], IFN-α [8.42 (6.31, 14.89) vs. 0.50 (0.30, 0.83) pg/ml], and IFN-γ [17.93 (12.75, 32.44) vs. 7.43 (0.00, 14.74) pg/ml], with all differences being statistically significant (all P<0.05). Conclusion: AMN following COVID-19 can present with wedge-shaped dark red lesions in the macular area, often accompanied by cotton wool spots and retinal vasculitis. Additionally, there is a significant elevation in various inflammatory cytokines in the serum.

Objective: To construct a novel chimeric antigen receptor T (CAR-T) cell targeting CD138 and to investigate its cytotoxicity against myeloma cells. Methods: The hybridoma strain that can stably secrete the CD138 monoclonal antibody (mAb) was prepared and obtained through monoclonal antibody screening technology. The hybridoma strain cells were intraperitoneally injected into mice to produce ascites containing monoclonal antibodies, which were then collected and purified to obtain pure CD138 mAb. Further examinations were performed to assess the biological characteristics of CD138 mAb. The variable region sequence of this antibody was amplified through reverse transcription polymerase chain reaction and was used as the antigen recognition domain of CD138 CAR, which was subsequently expressed on the surface of T cells by lentiviral infection. Flow cytometry was employed to assess the phenotype of CD138 CAR-T cells. In vitro cytotoxicity and degranulation assays were performed to evaluate their antitumor effects. Results: â We successfully prepared anti-human CD138 antibody hybridoma cell lines and screened a hybridoma cell strain, 5G2, which could persistently and stably secrete the anti-CD138 antibody. â¡ The purified CD138 (5G2) mAb can especially recognize CD138(+) cells with a binding affinity constant (K(D)) of 6.011×10(-9) mol/L and showed no significant binding activity with CD138(-) cells. â¢The variable region sequence of the CD138 (5G2) antibody was obtained using molecular cloning technology, and CD138 (5G2) CAR was successfully constructed and expressed on T cells through lentivirus infection and, concurrently, demonstrated effective binding to recombinant human CD138 protein.⣠The proliferation of T cells transduced with the CD138 (5G2) CAR was highly efficient. The phenotype analysis revealed that CD138 (5G2) CAR-T cells exhibited a greater tendency to differentiate into central memory T cells and memory stem T cells, with a reduced proportion of terminally differentiated effector memory subsets. â¤CD138 (5G2) CAR-T cells demonstrated specific cytotoxicity against CD138(+) myeloma cell line H929, whereas CD138(-) cell line K562 remained unaffected. The percentage of residual H929 cells was (12.92±8.02) % after co-culturing with CD138 (5G2) CAR-T cells, while (54.25±15.79) % was left in the Vector-T group (Eâ¶T=1â¶2; P<0.001). â¥Results of degranulation assays demonstrated a significant activation of CD138 (5G2) CAR-T cells after co-culture with the H929 cell line, whereas no significant activation was observed in Vector-T cells [ (25.78±3.35) % vs (6.13±1.30) %, P<0.001]. â¦After co-culturing with CD138(+) cells, CD138 (5G2) CAR-T cells exhibited a significant increase in cytokine secretion compared to the Vector-T group [interleukin-2: (1 697.52±599.05) pg/ml vs (5.07±1.17) pg/ml, P<0.001; interferon-γ: (3 312.20±486.38) pg/ml vs (9.28±1.46) pg/ml, P<0.001; and tumor necrosis factor-α: (1 837.43±640.49) pg/ml vs (8.75±1.65) pg/ml, P<0.001]. However, no significant difference was observed in cytokine secretion levels between the two groups after co-culturing with CD138(-) cells. Conclusion: This study successfully prepared a novel monoclonal antibody against CD138, and CAR-T cells constructed with the antigen recognition domain derived from this 5G2 mAb demonstrated effective antitumor activity against myeloma cells. This can be used as a new option for the detection of the CD138 antigen and proposes a novel strategy for multiple myeloma immunotherapy.

OBJECTIVE: To investigate the effects of an adeno-associated virus (AAV2) vector expressing secretory transforming growth factor-ß (TGF-ß) type â ¡ receptor (sTßRâ ¡) extracellular domain-IgG2a Fc fusion protein (sTßRâ ¡-Fc) on proliferation and migration of triple-negative murine breast cancer 4T1 cells in mice. METHODS: The pAAV-sTßRâ ¡-Fc vector expressing sTßRâ ¡-Fc fusion protein constructed by molecular cloning, the capsid protein-expressing vector pAAV2 and the helper vector were co-transfected into HEK 293T cells to prepare the recombinant AAV2-sTßRâ ¡ virus, which was purified by density gradient centrifugation with iodixanol. Western blotting was used to examine the effects of AAV-sTßRâ ¡ virus on Smad2/3 phosphorylation in 4T1 cells and on expression levels of E-cadherin, vimentin and p-Smad2/3 in 4T1 cell xenografts in mice. BALB/c mice bearing subcutaneous xenografts of luciferase-expressing 4T1 cells received intravenous injections of AAV-sTßRâ ¡ virus, AAV-GFP virus or PBS (n=6) through the tail vein, and the proliferation and migration of 4T1 cells were analyzed with in vivo imaging. Ki67 expression in the tumor tissues and sTßRâ ¡ protein expressions in mouse livers were detected with immunohistochemistry and immunofluorescence staining, and tumor metastases in the vital organs were examined with HE staining. RESULTS: The recombinant pAAV-sTßRâ ¡-Fc vector successfully expressed sTßRâ ¡ in HEK 293T cells. Infection with AAV2-sTßRâ ¡ virus significantly reduced TGF-ß1-induced Smad2/3 phosphorylation in 4T1 cells and effectively inhibited proliferation and lung metastasis of 4T1 xenografts in mice (P<0.05). In the tumor-bearing mice, intravenous injection of AAV-sTßRâ ¡ virus significantly increased E-cadherin expression, reduced vimentin and Ki67 protein expressions and Smad2/3 phosphorylation level in the tumor tissues (P<0.05 or 0.01), and induced liver-specific sTßRâ ¡ expression without causing body weight loss or heart, liver, spleen or kidney pathologies. CONCLUSION: The recombinant AVV2 vector encoding sTßRâ ¡ extracellular domain is capable of blocking the TGF-ß signaling pathway to inhibit the proliferation and lung metastasis of 4T1 cells in mice.

Objective: To investigate the effects of glycopyrrolate on intestinal spasm and hemodynamics in painless colonoscopy. Methods: A total of 100 patients who were scheduled to undergo painless colonoscopy were selected as the study subjects and randomly divided into two groups by a computerized number method. Ten patients in both groups dropped out because of disruption of the study protocol, and 45 patients from each group were included in the final analysis. Before anesthesia induction, patients in group glycopyrrolate (group G) were injected with 0.2 mg glycopyrrolate, while those in congtrol group (group C) were injected with an equal amount of saline. The heart rate, systolic blood pressure, and diastolic blood pressure were recorded at T0 (baseline period), T1 (after anesthesia induction), T2 (colonoscopy over sigmoid colon), T3 (colonoscopy over the liver region), T4 (after the end of examination), and T5 (at the awakening phase), and the degree of intestinal spasm was assessed intraoperatively using the Likert's four-point scale. The numerical rating scale (NRS) was used to assess preoperative and postoperative pain. The incidence of adverse events was recorded. Results: The general data at baseline were not statistically different between the two groups (P>0.05). During the procedure, patients in group G had lower intraoperative intestinal spasm scores than those in group C (P=0.028). Intraoperative hypotension and bradycardia occurrence were lower in group G than in group C (P<0.05), and intraoperative norepinephrine use was also lower than in the group C (P=0.034). Postoperative visual analog scale pain scores were lower in group G (P=0.047), but patients who used glycopyrrolate had a higher proportion of dry mouth (P=0.035). Conclusion: During painless colonoscopy, preoperative administration of glycopyrrolate significantly improved intraoperative hemodynamic fluctuations, reduced the incidence of hypotension and bradycardia, and relieved postoperative pain. However, glycopyrrolate use resulted in the risk of dry mouth.

Objective: To investigate the effect of virtual reality visual training on remodeling optic nerve structures of glaucoma patients and analyze the influencing factors of visual training effect. Methods: A prospective non-randomized controlled trial was conducted. Glaucoma patients who presented to the Department of Ophthalmology, Beijing Shijitan Hospital between October 2021 and October 2022 were collected and divided into the training group or the control group according to their intentions. The training group accepted 3 months of visual training, while the control group did not. Optical coherence tomography was used to examine the disc edge area, cup volume, disc area, cup-to-disc ratio, and other parameters of the optic disc of both eyes of the patients at enrollment and after 3 months, and the changes of each parameter in the two groups were analyzed. Multivariate analysis was performed in the training group to investigate the effects of sex, age, visual field index, and mean defect on visual disc structure changes during visual training. Results: A total of 53 glaucoma patients (101 eyes) were included in the final analysis, among which the training group consisted of 27 cases (51 eyes), with 19 males and 8 females, and the age range was 48.0 (40.0, 61.0) years old. The control group comprised 26 cases (50 eyes), with 26 males and 11 females, and the age range was 54.0 (38.0, 63.0) years old. Compared with the control group, the deviation of cup volume was -0.006(-0.050, 0.015)mm3 (P<0.05), and the deviation of disc edge area was 0.00(-0.04, 0.05)mm2 (P<0. 05)in the visual training group after 3 months of visual training. The gender (OR=4.217, 95%CI=1.188-14.966) may be the influence factor of rim area. While,the mean defect (OR=1.526, 95%CI=0.245-9.491) was not that influential on rim area change. Conclusions: Visual training can increase the disc area and decrease the optic cup volume of the optic nerve in glaucoma patients. The rim area may be increased more easily after visual training in male glaucoma patients.

Objective: To evaluate the efficacy and safety of glaucoma drainage implants(XEN-45 Gel Stent) for glaucoma treatment. Methods: A prospective study was conducted to continuously collect the clinical data of patients who were diagnosed with glaucoma and underwent XEN-45 Gel Stent implantation in the Ophthalmology Department of Peking University People's Hospital from January 2022 to August 2023. The visual acuity, intraocular pressure, number of glaucoma medications, and success rate of the patients were analyzed before and after surgery at 1 day, 1 week, 1 month, 3 months, 6 months, 12 months, and 18 months. The differences in intraocular pressure and number of glaucoma medications among primary open-angle glaucoma, primary angle closure glaucoma, secondary glaucoma, and different implantation methods of XEN-45 Gel Stent among patients with primary open-angle glaucoma were compared. The intraoperative and postoperative complications were observed, and the risk factors for needling and surgical complete success were analyzed. Results: A total of 48 eyes from 48 patients were included in this study, comprising 27 males and 21 females, with a mean age of (54.4±18.0) years and the disease duration was 36.0(7.3, 81.0) months.There were 28 cases of primary open-angle glaucoma, 4 cases of primary angle closure glaucoma, and 16 cases of secondary glaucoma.The follow-up period was 8.0 (3.0, 12.0) months. At 12 months after surgery, the intraocular pressure decreased from 20.5 (17.0, 26.0) mmHg to (13.5±3.3) mmHg (P<0.05), and the number of glaucoma medications decreased from 3.0 (3.0, 4.0) to 0.0 (0.0, 0.0) (P<0.05). The complete success rate and qualified success rate were 73.9% (17/23) and 91.3% (21/23), respectively. The most common postoperative complications were shallow anterior chamber in 6 cases (12.5%), hypotony in 3 cases (6.3%), and blocked stent in 3 cases (6.3%). The most common postoperative treatment was needling in 27 cases (56.3%). There was no significant difference in intraocular pressure among different types of glaucoma. In the comparison of postoperative effects of different surgical implantation methods for primary open-angle glaucoma, there were no statistically significant differences in intraocular pressure and the number of glaucoma medications at other follow-up time points except 1 month after surgery (P<0.05). Univariate logistic regression analysis did not find any risk factors associated with needling and surgical complete success. Conclusions: XEN-45 Gel Stent implantation is an effective and safe surgical option for different types of glaucoma patients in China, which can significantly reduce intraocular pressure and the use of glaucoma medications and has a high success rate. However, some patients may need needling or other treatments after surgery.
