    Abstract Objective: To explore the genetic basis for a child with Hemoglobin Santa Ana (Hb Santa Ana).
    Methods: The child was admitted to the Children's Hospital of Chongqing Medical University on August 4, 2013 due to anemia, splenomegaly and deepening urine color for 5 years. His clinical data were collected. Peripheral blood samples of the child and his parents were collected for routine blood test. The erythrocyte parameters of the child and his parents were determined with an automatic hemocyte analyzer. The hemoglobin components of the child and his parents were detected by high-performance liquid chromatography (HPLC). Common mutations associated with thalassemia were detected by Gap-PCR and PCR-reverse dot blotting (PCR-RDB). Rare variants of the globin genes were detected by next generation sequencing (NGS), and the result was verified by Sanger sequencing.
    Results: The child has shown mild to moderate hemolytic anemia. Routine blood test showed that he had lower hemoglobin (90 g/L) and mean corpuscular hemoglobin concentration (267 g/L) but a higher reticulocyte ratio (0.141), which indicated hypopigmented hyperplastic anemia. Analysis of hemoglobin component showed that his hemoglobin F was elevated to 10.7%, which indicated abnormal synthesis of β globin peptide chain. HPLC analysis showed an abnormal peak accounting for 4.5% of the total area. Neither of his parents was found to have abnormal results for routine blood test and hemoglobin component analysis. No common globin gene variant was detected in the child. Gene sequencing revealed that the child has harbored a heterozygous variant of HBB: c.266T>C, which was de novo in origin. Based on the guidelines of American College of Medical Genetics and Genomics, the variant was predicted to be pathogenic.
    Conclusion: The heterozygous HBB: c.266T>C variant probably underlay the hemolytic anemia associated with Hb Santa Ana in this patient.

    Abstract Background: The aim of this study was to assess the clinical and radiographic outcomes of cubitus varus treatments based on different fixation methods: Locking plate vs. Kirschner-wires (K-wires) and cast fixation.
    Methods: This retrospective study of 28 patients was performed in lateral-wedge osteotomy for cubitus varus deformity in our hospital from July 2018 to July 2020. 14 patients in group A were treated by locking plate after lateral closing-wedge osteotomy, whereas other 14 patients were treated by K-wires in group B. We measured the bony union and carrying angle. The clinical and radiographic outcomes were assessed according to the Bellemore criteria.
    Results: No nonunion, neurovascular injury or myositis ossificans was noted at follow-up. In group A, 1 patient with lateral condylar prominence was found. In group B, 2 patients with pinning site infection were treated successfully with oral antibiotics and 2 patients needed revision surgery for residual varus. According to the Bellemore criteria, statistically significant difference was noted between the two groups
    Conclusions: Compared with K-wires and cast fixation, we recommend the wedge osteotomy with lateral locking plate to treat the cubitus varus deformity because locking plate could achieve better functional and cosmetic results and stabilize the distal humerus rigidly.

    Abstract Introduction: We aimed to investigate the association of iron metabolism-related parameters with 60-day mortality in critically ill patients with sepsis.
    Methods: Serum or urine concentrations of iron metabolism-related parameters on intensive care unit admission were measured in a prospective cohort of 133 eligible patients with sepsis according to the Sepsis-3 criteria, and these values were compared between survivors and nonsurvivors, categorized according to their 60-day survival status. Cox regression analyses were performed to examine the association between iron parameters and 60-day mortality. Kaplan-Meier methods were used to illustrate the differences in survival between different iron parameters.
    Results: Of the 133 patients included in the study, 61 (45.8%) had died by day 60. After adjusting for confounding variables, higher concentrations of serum iron (cut-off 9.5 μmol/mL) and higher concentrations of urine neutrophil gelatinase-associated lipocalin (uNGAL; cut-off 169.3 ng/mL) were associated with a significantly greater risk of death in the Cox regression analysis. These two biomarkers combined with Sequential Organ Failure Assessment (SOFA) scores increased the area under the receiver operating characteristic (AUROC) curve to 0.85.
    Discussion: These findings suggest that higher concentrations of serum iron and uNGAL are each associated with higher 60-day mortality, and they add significant accuracy to this prediction in combination with SOFA.

    Abstract The study focuses on the control of nonlinear dynamic systems in the presence of parameter uncertainties, unmodeled dynamics, and external disturbances. The lumped perturbation is assumed to be bounded within a polynomial in the system state with the polynomial parameters and degrees unknown a priori such that it accommodates a quite wider range dynamic systems. Based on the studies in recent super-twisting algorithm designs and the idea from adaptive sliding mode control for nonlinear systems with uncertainties, we propose a novel adaptive super-twisting algorithm with exponential reaching law, or exponential super-twisting algorithm (ESTA), for the high-stability and acceptable accuracy control of the aimed nonlinear dynamics. The stability analysis and practical finite-time (PFT) convergence are proven using Lyapunov theory and an intuitive analysis of the control behaviour. Simulations are performed to compare the proposed ESTA with the existing super-twisting method and the traditional proportional integral differential control. The simulation results demonstrate the effectiveness of the proposed ESTA in terms of the fastest settling time and the smallest overshoot.

    Abstract Objective: To compare the clinical characteristics of children with hemophagocytic lymphocytosis (HLH) associated with primary Epstein-Barr virus (EBV) infection and EBV reactivation, and explore the effects of different EBV infection status on the clinical indexes and prognosis of HLH.
    Methods: The clinical data of 51 children with EBV associated HLH treated in Henan Children's Hospital from June 2016 to June 2021 were collected. According to the detection results of plasma EBV antibody spectrum, they were divided into EBV primary infection-associated HLH group (18 cases) and EBV reactivation-associated HLH group (33 cases). The clinical features, laboratory indexes and prognosis of the two groups were analyzed and compared.
    Results: There were no significant differences in age, gender, hepatomegaly, splenomegaly, lymphadenopathy, neutrophil count in peripheral blood, hemoglobin content, platelet count, plasma EBV-DNA load, lactate dehydrogenase, alanine aminotransferase, aspartate aminotransferase, albumin, fibrinogen, triglyceride, ferritin, hemophagocytosis in bone marrow, NK cell activity and sCD25 between the two groups(
    Conclusion: EBV reactivation-associated HLH is more likely to cause central nervous system involvement and the prognosis is worser than EBV primary infection-associated HLH, which requires intensive treatment.

    Abstract After a universal two-child policy was introduced in China in 2016, studies have been published using women's fertility intentions to forecast future births; however, the recommended algorithms need to be improved. In this study, an algorithm based on the method of limiting factors is developed to retrospectively forecast annual births in Xi'an City in the first three years of policy implementation, i.e. 2016-2018. The 2015 Xi'an Fertility Survey (sample: 560 one-child mothers) showed that 17% of mothers intended to have a second child, 30% were undecided and 53% did not intend to do so at the end of 2015. The low forecast variant based on the updated algorithm indicates that there would be a baby boom in 2016-2018, but the annual births would increase by 13% at most. The forecasting results are basically consistent with the official reports on annual births. This study emphasizes the importance of appropriately adjusting all fertility intentions in birth forecasting, helps to understand women's fertility behaviour and evaluate the effects of implementing the universal two-child policy, and has important implications for China's population and family planning work.

    Abstract Akkermansia muciniphila (A. muciniphila) is an anaerobic bacterium that widely colonizes the mucus layer of the human and animal gut. The role of this symbiotic bacterium in host metabolism, inflammation, and cancer immunotherapy has been extensively investigated over the past 20 years. Recently, a growing number of studies have revealed a link between A. muciniphila, and aging and aging-related diseases (ARDs). Research in this area is gradually shifting from correlation analysis to exploration of causal relationships. Here, we systematically reviewed the association of A. muciniphila with aging and ARDs (including vascular degeneration, neurodegenerative diseases, osteoporosis, chronic kidney disease, and type 2 diabetes). Furthermore, we summarize the potential mechanisms of action of A. muciniphila and offer perspectives for future studies.

    Abstract Although carbon tax policies can effectively restrain energy consumption and reduce pollution, they will also affect the welfare of residents through a price mechanism. We explore the impact of energy price increases that are caused by possible carbon tax policies on the welfare of residents in China with a quadratic almost ideal demand system (QUAIDS) model. The estimated elasticities show that the income elasticity of coal demand is −0.741 for urban residents, compared to 0.392 for rural residents. The cross-price elasticity shows that China's residential energy consumption has moved up the clean energy ladder. Based on the above reliable elasticity estimates, the welfare effects are analyzed in the residential consumption system. The overall welfare loss for residents increases with the level of carbon tax. A carbon tax on all energy sources is a regressive policy for China, and when the carbon tax rate reaches the world average, of 30 USD/tCO₂e, the welfare loss for low-income and high-income residents is 1.55% and 0.62% respectively. However, the separate imposition of carbon taxes on different energy sources shows the heterogeneity of the welfare impacts of carbon taxes. At the national and urban levels, the distribution effects of carbon taxes are regressive for coal, LPG, and electricity, progressive for gasoline, and distributional neutral for natural gas. In rural areas, however, the welfare distribution effect of the carbon tax on diesel, LPG, and natural gas are progressive, and the welfare effects of carbon taxes on electricity show an inverted U-shaped distribution. Our findings are conducive to the development of a differentiated carbon tax policy by the Chinese government.

    Abstract China’s coal-based energy structure makes its carbon peak and neutrality goals very challenging. As a result, optimizing the energy structure has become an important means, and researching its influencing factors and trends has become the foundation and prerequisite for policy formulation related to energy structure optimization. Especially after the severe economic crisis, the economic structure has undergone profound changes, and the impact of related factors on the energy structure has also changed. This study adopts regression methods considering heteroskedasticity and cross-section correlation to study the panel data of 30 provinces in China and obtains the changes in the relationship between fossil and non-fossil fuel consumption in different regions and their influencing factors after two global financial crises. Research results show that China’s energy consumption tends to decouple from GDP. Income structure changes, especially trade changes, are important factors in influencing energy consumption and energy structure. The deviation between energy resource distribution and consumption distribution tends to increase. Regional heteroskedasticity is evident in the impact of urbanization development models, energy prices, and efficiency.

    Abstract Human microtubule-associated protein Tau (τ) is abundant in the axons of neurons where it stabilizes microtubule bundles; abnormally hyperphosphorylated τ is a hallmark of Alzheimer’s disease (AD) and related tauopathies. The hyperphosphorylation events can be recognized by phosphotyrosine-recognition domain SH2 (Src homology 2) to elicit downstream τ signaling in AD pathology. In this study, a comprehensive binary interaction map (CBIM) of all the 6 τ phosphotyrosine sites with 120 SH2 domains in the human genome was systematically created at structural level using computational analyses and binding assays, from which we were able to identify those of strong and moderate binding pairs of sites to domains. It is found that the SH2-recognition specificity of different τ phosphotyrosine sites has been evolutionally optimized to become roughly orthogonal to each other, and thus these site phosphorylations would regulate different but probably partially overlapped biological functions in τ signaling. Some SH2 groups such as SRC, RIN, PLCG, SOCS and SH2D were revealed to have effective binding potency as compared to others; they could be regarded as potential τ-associated proteins to transduce the downstream signaling. We further determined the systematic binding affinities of 6 τ-phosphopeptides to the 11 SH2 domains in SRC group, from which the FYN-τ¹⁸ and YES-τ²⁹ pairs were identified as strong binders. Subsequently, rational molecular design was performed on τ¹⁸ and τ²⁹ to derive a number of τ-phosphopeptide mutants with increased affinity; they are self-inhibitory candidates to competitively target τ hyperphosphorylation events in AD. In addition, it is revealed that the primary anchor pY₀ and secondary anchor X₊₃ of τ-phosphopeptides play an important role in SRC-group SH2 recognition, which confer stability and specificity to the SH2–phosphopeptide binding, respectively.
