Objective To analyze the trends in the disease burden of schistosomiasis in China from 1992 to 2021, and to project the disease burden of schistosomiasis in China from 2022 to 2030, so as to provide insights into the elimination of schistosomiasis in China. Methods The prevalence, age-standardized prevalence, disability-adjusted life year (DALYs) rate and age-standardized DALYs rate of schistosomiasis, as well as the years lost due to disability (YLDs) rate and age-standardized YLDs rate of anemia attributable to Schistosoma infections in China, the world and different socio-demographic index (SDI) regions were captured from the Global Burden of Disease Study 2021 (GBD 2021) data resources, and the trends in the disease burden due to schistosomiasis were evaluated with estimated annual percentage change (EAPC) and its 95% confidence interval (CI). In addition, the age, period and cohort effects on the prevalence of schistosomiasis were examined in China using an age-period-cohort (APC) model, and the disease burden of schistosomiasis was predicted in China from 2022 to 2030 using a Bayesian age-period-cohort (BAPC) model. Results The age-standardized prevalence and DALYs rate of schistosomiasis, and the age-standardized YLDs rate of anemia attributable to Schistosoma infections were 761.32/10⁵, 5.55/10⁵ and 0.38/10⁵ in China in 2021. These rates were all lower than the global levels (1 914.30/10⁵, 21.90/10⁵ and 3.36/10⁵, respectively), as well as those in the medium SDI regions (1 413.61/10⁵, 12.10/10⁵ and 1.93/10⁵, respectively), low-medium SDI regions (2 461.03/10⁵, 26.81/10⁵ and 4.48/10⁵, respectively), and low SDI regions (5 832.77/10⁵, 94.48/10⁵ and 10.65/10⁵, respectively), but higher than those in the high SDI regions (59.47/10⁵, 0.49/10⁵ and 0.05/10⁵, respectively) and high-medium SDI regions (123.11/10⁵, 1.20/10⁵ and 0.12/10⁵, respectively). The prevalence and DALYs rate of schistosomiasis were higher among men (820.79/10⁵ and 5.86/10⁵, respectively) than among women (697.96/10⁵ and 5.23/10⁵, respectively) in China in 2021, while the YLDs rate of anemia attributable to Schistosoma infections was higher among women (0.66/10⁵) than among men (0.12/10⁵). The prevalence of schistosomiasis peaked at ages of 30 to 34 years among both men and women, while the DALYs rate of schistosomiasis peaked among men at ages of 15 to 19 years and among women at ages of 20 to 24 years. The age-standardized prevalence of schistosomiasis showed a moderate decline in China from 1992 to 2021 relative to different SDI regions [EAPC = -1.51%, 95% CI: (-1.65%, -1.38%)], while the age-standardized DALYs rate [EAPC = -3.61%, 95% CI: (-3.90%, -3.33%)] and age-standardized YLDs rate of anemia attributable to Schistosoma infections [EAPC = -4.16%, 95% CI: (-4.38%, -3.94%)] appeared the fastest decline in China from1992 to 2021 relative to different SDI regions. APC modeling showed age, period, and cohort effects on the trends in the prevalence of schistosomiasis in China from 1992 to 2021, and the prevalence of schistosomiasis appeared a rise followed by decline with age, and reduced with period and cohort. BAPC modeling revealed that the age-standardized prevalence and age-standardized DALYs rate of schistosomiasis, and age-standardized YLDs rate of anemia attributable to Schistosoma infections all appeared a tendency towards a decline in China from 2022 to 2030, which reduced to 722.72/10⁵ [95% CI: (538.74/10⁵, 906.68/10⁵)], 5.19/10⁵ [95% CI: (3.54/10⁵, 6.84/10⁵)] and 0.30/10⁵ [95% CI: (0.21/10⁵, 0.39/10⁵)] in 2030, respectively. Conclusions The disease burden of schistosomiasis appeared a tendency towards a decline in China from 1992 to 2021, and is projected to appear a tendency towards a decline from 2022 to 2030. There are age, period and cohort effects on the prevalence of schistosomiasis in China. Precision schistosomiasis control is required with adaptations to current prevalence and elimination needs.

AIM:To observe the defocus state and myopia control in myopic children wearing single-vision, defocus, and orthokeratology lenses using multispectral refraction topography(MRT).METHODS: A total of 279 myopic patients aged 8-14 years old, with a spherical equivalent(SE)from -7.00 to -0.50 D, treated at the Chengdu Aier Eye Hospital from June 2022 to December 2023. Patients who volunteered for the study were assigned to three groups. A total of 94 cases were provided with single-vision spectacle lenses(SVL group), 90 cases received individualized ocular refraction customization(IORC group), and 95 cases received orthokeratology lenses(OK group). Simultaneously, the three groups were further categorized into low(-3.00 to -0.50 D), moderate(-6.00 to -3.25 D), and high myopia(-7.00 to -6.25 D)groups according to different SE. MRT was used to measure and compare the defocus changes of the retina in supperior, inferior, nasal, and temporal quadrants(RDV-S, RDV-I, RDV-N, RDV-T), and three angles of field of view, including 0-15°, 15°-30°, and 30°-45°(RDV-15, RDV-30, RDV-45)in the three groups(the data divide for the connected regions is grouped to the latter group). A one-way analysis of variance was used for intergroup comparisons. Univariate and multivariate linear regression analyses were used to analyze the factors related to changes in the axial length(AL)at 1 a after intervention.RESULTS:There were significant differences in 1-year SE and AL growth among patients in the SVL, IORC, and OK groups before and after intervention(P<0.001). The 1-year SE and the difference of AL growth in patients with low myopia was significantly different among SVL, IORC, and OK groups(P<0.001); however, there was no significant difference between the IORC and OK groups(P>0.05); there were significant differences in the SE and AL growth changes between the OK group and the IORC and SVL groups in moderate myopia(P<0.001); and there were significant differences between the OK group and the IORC and SVL groups in SE and AL growth of high myopia group after wearing lenses for 1 a(P<0.001), while there were no significant differences between the IORC and SVL groups(P>0.05). In addition, there were significant differences in the relative peripheral refractive errors(RPRE)of 4 quadrants and 3 eccentric regions among the three groups of patients in different degrees of myopia groups(P<0.001). Pair-wise comparison of the growth difference of eccentric D-RDV-15 in low myopia group after wearing lenses for 1 a showed significant differences between the SVL, IORC, and OK groups(P<0.001), but no significant differences between the IORC and OK groups(P>0.05). The angle of field of view D-RDV-30 in moderate myopia subgroups was statistically different between the SVL group and the IORC and OK groups after wearing lenses for 1 a(P<0.001), while the IORC and OK groups showed no significant differences(P>0.05); the angle of field of view D-RDV-15 in high myopia subgroups was statistically different between the OK group and the IORC and SVL groups after wearing lenses for 1 a(P<0.001), but there was no significant difference between the IORC and SVL groups(P>0.05). Univariate and multivariate linear regression model analysis showed that the changes in D-TRVD, D-RDV-45, D-RDV-N, and D-RDV-I correlated with the increase in the difference in 1 a AL.CONCLUSION: MRT can be used to guide the clinical control of myopia. Myopia development is related to the peripheral retinal defocus state, and the difference of defocus quantity in the inferior nasal side at 30°-45° eccentricity may be a factor regulating the rapid progression of myopia.

ObjectiveTo investigate the clinical features and outcomes of recompensation in patients with autoimmune hepatitis （AIH）-related decompensated cirrhosis， to identify independent predictive factors， and to construct a nomogram prediction model for the probability of recompensation. MethodsA retrospective cohort study was conducted among the adult patients with AIH-related decompensated cirrhosis who were admitted to The Fifth Medical Center of PLA General Hospital from January 2015 to August 2023 （n=211）. The primary endpoint was achievement of recompensation， and the secondary endpoint was liver-related death or liver transplantation. According to the outcome of the patients at the end of the follow-up， the patients were divided into the recompensation group （n=16） and the persistent decompensation group（n=150）.The independent-samples t test was used for comparison of normally distributed continuous data with homogeneity of variance， and the Mann-Whitney U rank sum test was used for comparison of non-normally distributed continuous data with heterogeneity of variance； the chi-square test or the Fisher’s exact test was used for comparison of categorical data between groups； the Kaplan-Meier method was used for survival analysis； the Cox proportional-hazards regression model was used to identify independent predictive factors， and a nomogram model was constructed and validated. ResultsA total of 211 patients were enrolled， with a median age of 55.0 years and a median follow-up time of 44.0 months， and female patients accounted for 87.2%. Among the 211 patients， 61 （with a cumulative proportion of 35.5%） achieved recompensation. Compared with the persistent decompensation group， the recompensation group had significantly higher white blood cell count， platelet count （PLT）， total bilirubin （TBil）， alanine aminotransferase （ALT）， aspartate aminotransferase （AST）， total bile acid， prothrombin time， international normalized ratio （INR）， SMA positive rate， Model for End-Stage Liver Disease （MELD） score， Child-Pugh score， and rate of use of glucocorticoids （all P0.05）， as well as significantly lower age at baseline， number of complications， and death/liver transplantation rate （all P0.05）. At 3 and 12 months after treatment， the recompensation group had continuous improvements in AST， TBil， INR， IgG， MELD score， and Child-Pugh score， which were significantly lower than the values in the persistent decompensation group （all P0.05）， alongside with continuous increases in PLT and albumin， which were significantly higher than the values in the persistent decompensation group （P0.05）. The multivariate Cox regression analysis showed that baseline ALT （hazard ratio ［HR］=1.067， 95% confidence interval ［CI］： 1.010 — 1.127， P=0.021）， IgG （HR=0.463，95%CI：0.258 — 0.833， P=0.010）， SMA positivity （HR=3.122，95%CI：1.768 — 5.515， P0.001）， and glucocorticoid therapy （HR=20.651，95%CI：8.744 — 48.770， P0.001） were independent predictive factors for recompensation， and the nomogram model based on these predictive factors showed excellent predictive performance （C-index=0.87，95%CI：0.84 — 0.90）. ConclusionAchieving recompensation significantly improves clinical outcomes in patients with AIH-related decompensated cirrhosis. Baseline SMA positivity， a high level of ALT， a low level of IgG， and corticosteroid therapy are independent predictive factors for recompensation. The predictive model constructed based on these factors can provide a basis for decision-making in individualized clinical management.

ObjectiveTo investigate the distribution of traditional Chinese medicine （TCM） syndromes in intrahepatic cholestasis of pregnancy （ICP） and its association with perinatal outcomes， and to provide a basis for precise treatment based on TCM syndrome differentiation. MethodsA cross-sectional study was conducted among 275 patients with ICP who were admitted to The Affiliated Hospital of Chengdu University of Traditional Chinese Medicine from April 2023 to April 2025. A hierarchical cluster analysis was used to summarize TCM syndromes. The Kruskal-Wallis H test was used for comparison of non-normally distributed continuous data between groups， and the chi-square test was used for comparison of categorical data between groups. A multivariate Logistic regression analysis was used to identify the clinical features significantly associated with TCM syndrome. ResultsThe cluster analysis identified three core TCM syndromes among the 275 patients with ICP， i.e.， liver-gallbladder damp-heat syndrome （45.8%）， syndrome of blood deficiency generating wind （30.9%）， and liver depression and spleen deficiency syndrome （23.3%）. There was a significant difference in the distribution of TCM syndromes between different groups stratified by maternal age at delivery， parity， history of ICP recurrence， gestational weeks at disease onset， total bile acid （TBA）， alanine aminotransferase （ALT）， and comorbidity with gestational diabetes mellitus （GDM） （all P<0.05）. The multivariate Logistic regression analysis showed that<34 gestational weeks at disease onset was significantly associated with all three syndromes （damp-heat： odds ratio ［OR］=3.769， P<0.001； blood deficiency： OR=4.031， P<0.001； liver stagnation： OR=3.552， P<0.001）. Liver-gallbladder damp-heat syndrome was associated with maternal age ≥35 years at disease onset （OR=2.048， P=0.014）， parity ≥2 times （OR=1.921， P=0.034）， history of ICP recurrence （OR=2.404， P=0.030）， ALT ≥200 U/L （OR=2.051， P=0.018）， comorbidity with GDM （OR=1.944， P=0.029）， and TBA ≥40 μmol/L （OR=2.542， P=0.024）. The syndrome of blood deficiency generating wind syndrome was associated with maternal age ≥35 years （OR=2.939， P=0.003）， parity ≥2 time （OR=3.222， P=0.003）， history of ICP recurrence （OR=3.809， P=0.010）， ALT ≥200 U/L （OR=2.889， P=0.006）， comorbidity with GDM （OR=3.711， P=0.001）， and comorbidity with hypertensive disorders of pregnancy （OR=4.472， P=0.011）. Liver depression and spleen deficiency syndrome was associated with TBA ≥40 μmol/L （OR=2.995， P=0.044）. The analysis of perinatal outcomes showed that there were significant differences in mode of delivery， gestational weeks at the time of delivery， postpartum blood loss， and neonatal birth weight between the three groups with different TCM syndromes （all P<0.05）. ConclusionLiver-gallbladder damp-heat syndrome， syndrome of blood deficiency generating wind， and liver depression and spleen deficiency syndrome are the main TCM syndrome types in ICP， and the distribution of TCM syndromes is closely associated with clinical factors and perinatal outcomes， which provides a basis for precise TCM syndrome differentiation and individualized treatment.

Objective To evaluate the effect of dapagliflozin on myocardial function in early spontaneously hypertensive rats(SHR)with layer-specific global longitudinal strain(GLS).Methods A total of 45 male SHR aged 6 weeks were randomly divided into control group(normal saline),dapagliflozin group[1 mg/(kg·day)],and losartan group[10 mg/(kg·day)].Fifteen male Wistar-Kyoto(WKY)rats at same age with normal blood pressure were subjected and served as blank control group.During 8 weeks of intervention,systolic blood pressure(SBP)was measured,and conventional echocardiography and two-dimensional speckle tracking echocardiography(2DSTE)were performed and the results were collected to acquire the longitudinal strain of each layer of left ventricular(LV)myocardium.The parameters were compared among the groups.The pathological changes of myocardium were observed in each group of rats.Results Compared with the WKY group,LV ejection fraction(LVEF)and LV fraction shortening(LVFS)at week 8 were decreased in the control group(P＜0.05),but no such decreases were observed in the dapagliflozin group and the losartan group.The GLS of endo-myocardium(GLSendo)at the 6th week was decreased,and GLSendo,GLSmid and GLSepi at the 8th week were all decreased in the control group than the WKY group(all P＜0.05).But there were no statistical differences in the above 3 indicators in the dapagliflozin and losartan groups when compared with the WKY group(all P＞0.05).The pathological results showed that myocardial interstitial fibrosis was observed in the control group at the 6th week.Conclusion Dapagliflozin can effectively improve myocardial function in early SHR.

Objective : To investigate the expression and clinical significance of kynurenine-3-monooxygenase (KMO) in peripheral blood mononuclear cells ( PBMC ) ，synovial tissue ，and fibroblastic-like synovial cells (FLS) of rheumatoid arthritis (RA) patients． Methods : Peripheral blood samples from 25 healthy control ( HC) individuals and 25 patients diagnosed with RA were collected ，and real-time fluorescence quantitative PCR and Western blot were used to detect KMO gene and protein expression in PBMC of RA and HC groups，and to analyze the correlation between the expression level of the KMO gene in the PBMC of the RA patients and the indexes of the laboratory tests．Meanwhile，immunohistochemistry and immunofluorescence were used to detect KMO expression in synovial tissue and FLS in RA and HC groups． Results : ① KMO gene and protein expression in PBMC of RA group were higher than that of HC group，and the difference was statistically significant (P＜0. 001) ．② The level of KMO gene expression in PBMC of RA group was positively correlated with disease activity index 28 score，blood sedimentation，and rheumatoid factor (rs = 0. 417，P = 0. 038 ; r = 0. 545，P = 0. 005 ; rs = 0. 433，P = 0. 031) ， and had no correlation with C-reactive protein and anti-cyclic citrullinated polypeptide antibody．③ KMO expres- sion in synovial tissue of RA group was higher than that of HC group，and the difference was statistically significant (P＜0. 01) ; KMO expression in FLS of synovial tissue of RA group was higher than that of HC group，and the difference was statistically significant (P ＜0. 001) ． Conclusion KMO expression increases in PBMC ，synovial tissue and FLS of RA patients，and the level of KMO gene expression is correlated with the disease activity of RA patients，suggesting that KMO may promote the course of RA．

AIM: To explore the neuro-ophthalmological characteristics of acute macular neuroretinopathy(AMN)after SARS-CoV-2 infection.METHODS: A total of 8 patients(14 eyes), including 6 females and 2 males, who were diagnosed with AMN in the neuro-ophthalmology department of Xi'an No.1 Hospital(The First Affiliated Hospital of Northwest University)from December 27, 2022 to February 1, 2023 were included in the study. All patients had a history of SARS-CoV-2 infection before the disease, and the results of best corrected visual acuity(BCVA), non-contact indirect intraocular pressure measurement, fundus color photography, near infrared(IR), spectral-domain optical coherence tomography(SD-OCT), OCT angiography(OCTA), fundus fluorescein angiography(FFA), indocyanine green angiography(ICGA), visual field, visual evoked potential(VEP), and electroretinogram(ERG)were collected. Furthermore, the neuro-opthalmology characteristics of the included patients were analyzed and summarized.RESULTS: The included 8 patients aged from 20 to 43, with an average age of(30±6.63)years old. The patients had a history of SARS-CoV-2 infection 3 to 11(mean 5±3.51)d before the disease, and 6 out of 8 patients developed visual symptoms within 5 d of infection with SARS-CoV-2, with manifestated with decreased vision or visual scotoma. The visual acuity varied from 0.08 to 1.0, with visual field defect characterized by central, paracentral or peripheral scotoma. VEP showed prolongation latency of P100 or P2, and ERG revealed impaired function of retinal photoreceptor cell. In the early stage of the disease, the size and shape of early visual acuity, visual field, and extraretinal lesions in patients with AMN associated with SARS-CoV-2 infection may not match, and the lower the visual acuity, the later the VEP peaks.CONCLUSION: The neuro-ophthalmic features of SARS-CoV-2 infection-associated AMN require the attention of clinicians. In addition to multi-mode fundus imaging, clinicians should use a variety of methods to comprehensively evaluate visual function and prognosis of patients.

ObjectiveTo analyze the research status and trends in low-level occupational benzene exposure. Methods Articles on low-level occupational benzene exposure from Chinese and English journals from January 1st, 2000, to December 31th, 2022 were retrieved using the Web of Science and the China National Knowledge Infrastructure, and a bibliometric analysis was conducted. Results A total of 327 articles were included in the analysis, comprising 216 English articles and 111 Chinese articles. i) The number of articles published in English fluctuates greatly over the years, without a trend of continuous growth or decline. Authors from 359 research institutions in 45 countries and regions have published relevant English articles in 97 kinds of journals, involving 281 grants from 226 foundations. The top three countries in terms of articles amount were the United States, Italy, and China, with 81, 46, and 43 papers, respectively. The English articles mainly focused on mechanistic research at the genetic level, such as hematotoxicity, oxidative stress, and DNA damage. ii) The number of Chinese articles increased gradually after 2012, with the growth peak in 2017. Authors from 127 research institutions in 26 provinces, autonomous regions, and municipalities published Chinese articles in 51 kinds of journals, involving 154 grants from 78 foundations. Chinese articles tended to focus on benzene-induced hematotoxicity and occupational health damage. Conclusion Most studies on low-level occupational benzene exposure were conducted in China, the United States and Italy, focused on hematotoxicity. Monitoring international research topics and hotspots of the field has certain reference value for related research in China.

Objective: To investigate the incidence trend of sexually transmitted diseases (STDs) in Yantian District, Shenzhen City, Guangdong Province from 2008 to 2022, and the effects of age, period, and cohort on STDs incidence, so as to provide the basis for formulating control measures for STDs. Methods: Data of reported STDs cases (syphilis, gonorrhea, genital Chlamydia trachomatis infections, condyloma acuminatum and genital herpes) among population aged 15 to 64 years in Yantian District from 2008 to 2022 were collected through the Chinese Disease Control and Prevention Information System. The temporal and population distribution of STDs were descriptively analyzed. Trends in incidence of STDs were analyzed using average annual percent change (AAPC). Impacts of age, period and cohort on the incidence of STDs were analyzed by an age-period-cohort model. Results: A total of 6 156 cases of STDs aged 15 to 64 years were reported from 2008 to 2022, and the average annual incidence was 229.92/105. The overall incidence showed an upward trend (AAPC=2.409%, P<0.05), and an upward trend among females (AAPC=5.846%, P<0.05), but the trend was not statistically significant among males (AAPC=0.193%, P>0.05). The incidence of STDs showed an increasing trend followed by a decreasing trend with the increase of age. The incidence trend among males was consistent with the overall population, reaching its peak in the age group of 30 to 34 years (371.04/105), while the incidence among females showed an increasing trend with the increase of age, peaking in the age group of 60 to 64 years (442.15/105). Compared with 2013-2017, the incidence risk of STDs showed an increasing trend in 2018-2022 (RR=1.349, 95%CI: 1.217-1.495). Compared with the birth cohort of 1975-1979, the incidence risk of STDs in 1980-2005 birth cohort showed an increasing trend, with the highest incidence risk in 2000-2004 birth cohort (RR=4.178, 95%CI: 2.717-6.423). Conclusions The overall incidence of STDs among residents aged 15 to 64 years in Yantian District from 2008 to 2022 appeared a tendency towards a rise. Age, period and cohort all had impacts on the incidence, with a greater effect among females than males.
