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.

ObjectiveTo explore the sensory processing characteristics of preschool children with autism spectrum disorder （ASD）， and to provide a theoretical basis for early screening and intervention training of ASD. MethodsA total of 215 preschool children with ASD and170 typically developed （TD） children were investigated with a basic situation questionnaire and sensory processing measure （SPM）. The two groups were stratified according to age and gender， and the differences of scores in sensory domains were compared to analyze the sensory processing characteristics of preschool children with ASD. ResultsThe scores of social participation， vision， hearing， touch， taste and smell， body awareness， balance and motion， planning and ideas， and total sensory system in children with ASD were all higher than those in children with TD （all P<0.01）. The highest degree of abnormality was found in hearing and the lowest degree in taste and smell in children with ASD. The results of Spearman correlation analysis showed that in the 4-year-old and 5-year-old children with ASD， the scores of vision （r_s=-0.200， P= 0.033） and hearing （r_s=-0.194， P=0.040） decreased with age. There was no correlation between the scores of other developmental quotients and age （all P>0.05）. Boys and girls with ASD had higher scores in all developmental quotients than TD children （P<0.01）. However， there was no significant gender difference in any developmental quotients of ASD children （all P>0.05）. ConclusionSensory processing abnormalities are common in preschool children with ASD， which are different from those of TD children in multiple sensory domains. Sensory processing abnormalities may be used as an indicator for early screening of ASD， and it is necessary to conduct corresponding intervention training for sensory processing abnormalities in children with ASD.

AIM: To investigate the sensitization of flavonoids from Tetrastigma hemsleyanum (FTH) on gefitinib (GEF)-resistant lung adenocarcinoma cells. METHODS: The viabilities of A549 and A549/GR cells treated with FTH and GEF were detected by MTT method. The apoptotic rates and cell cycles of A549/GR cells treated with FTH and GEF were detected by Flow cytometry. The anti-tumor effects of flavonoids from FTH and GEF were assayed in A549/GR tumor-bearing mice. The expressions of proteins (PTEN, PI3K, p-PI3K, AKT, p-AKT) were detected by Western blot analysis. RESULTS: Compared with GEF group, FTH significantly enhanced the inhibition of GEF on the proliferation of A549/GR cells (P< 0.05). Combination with FTH and GEF significantly increased the apoptosis of A549/GR cells which were arrested at the G

To address the increasing need for detecting and validating protein biomarkers in clinical specimens, mass spectrometry (MS)-based targeted proteomic techniques, including the selected reaction monitoring (SRM), parallel reaction monitoring (PRM), and massively parallel data-independent acquisition (DIA), have been developed. For optimal performance, they require the fragment ion spectra of targeted peptides as prior knowledge. In this report, we describe a MS pipe-line and spectral resource to support targeted proteomics studies for human tissue samples. To build the spectral resource, we integrated common open-source MS computational tools to assemble a freely accessible computational workflow based on Docker. We then applied the workflow to gen-erate DPHL, a comprehensive DIA pan-human library, from 1096 data-dependent acquisition (DDA) MS raw files for 16 types of cancer samples. This extensive spectral resource was then applied to a proteomic study of 17 prostate cancer (PCa) patients. Thereafter, PRM validation was applied to a larger study of 57 PCa patients and the differential expression of three proteins in prostate tumor was validated. As a second application, the DPHL spectral resource was applied to a study consisting of plasma samples from 19 diffuse large B cell lymphoma (DLBCL) patients and 18 healthy control subjects. Differentially expressed proteins between DLBCL patients and healthy control subjects were detected by DIA-MS and confirmed by PRM. These data demonstrate that the DPHL supports DIA and PRM MS pipelines for robust protein biomarker discovery. DPHL is freely accessible at https://www.iprox.org/page/project.html?id=IPX0001400000.

Objective To explore the effect of electroacupuncture intervention on tumor growth and PCNA expression in HepG2 nude mice.Methods Thirty-two nude mice were randomized to electroacupuncture, electrostimulation, model and blank control groups, 8 mice each. A nude mouse model of subcutaneous tumor was made with HepG2. The electroacupuncture group received electroacupuncture at points Zusanli and Sanyinjiao on bilateral lower limbs and the electrostimulation group, direct electrical stimulation of the same points. The tumor volume, the tumor/weight ratio and the tumor growth inhibition rate were observed. PCNA expression in the tumor tissue was determined.Results There was no statistically significant pre-/post-intervention difference in the tumor volume in the electroacupuncture, electrostimulation and model groups (P>0.05). There was no statistically significant post-intervention difference in the tumor volume between the electroacupuncture or electrostimulation group and the model group (P>0.05), but tumor growth tended to slow in the electroacupuncture group. There was no statistically significant pre-/post-intervention difference in the nude mouse weight in every group (P>0.05). There was a statistically significant post-intervention difference in the tumor/weight ratio between the electroacupuncture group and the electrostimulation or model group (P<0.05), but no statistically significant post-intervention difference in the tumor/weight ratio between the electrostimulation and model groups (P>0.05). There was a statistically significantpost-intervention difference in the tumor growth inhibition rate between the electroacupuncture and electrostimulation groups (P<0.05). There was a statistically significant post-intervention difference in the PCNA expression level between the electroacupuncture or electrostimulation group and the model group (P<0.05), no statistically significant post-intervention difference in the PCNA expression level between the electroacupuncture and electrostimulation groups (P>0.05).Conclusion Electroacupuncture can delay HepG2 tumor growth to a certain extent.

Objective To investigate the role of mitochondrial cytochrome c on hepatocyte apoptosis in non-alcoholic fatty liver disease in rabbits and its pathogenesis.Methods Forty Japanese white rabbits were randomly assigned to control group and model group.The model group was divided into three subgroups: 4-week, 6-week, and 8-week groups, with 10 rabbits in each group.The model groups were subcutaneously injected with peanut oil (1.2 mL/kg), twice a week for 4 weeks, 6 weeks or 8 weeks.The rabbits of all groups were killed at the right time.Serum samples were collected to detect the serum biochemical index levels.Liver tissue samples were taken for pathological observation using HE staining.The hepatocyte apoptosis index ( AI ) was measured by flow cytometry, and mitochondrial permeability transition pore ( MPTP) was evaluated by ultraviolet spectrophotometry.Immunohistochemistry was employed to detect the hepatic expressions of Bcl-2, Bax, CYT C and caspase-3.Western blot was performed to detect the changes of CYT C and caspase-3 protein expressions.Results The model groups showed hepatic injury and high level of TC, TG, CRP, IL-6 and TNF-αbeginning from 4 weeks.With the NAFLD process, the hepatocyte apoptosis index was significantly increased at 4-8 weeks and the MPTP was gradually increased.In the model group, hepatic Bcl-2, Bax, CYT C and caspase-3 expressions were increased steadily with the time passing.Conclusions NAFLD-induced liver damage is associated with apoptosis, and the mitochondrial cytochrome c-mediated apoptotic pathway plays a role in the occurrence of NAFLD.
