Abstract
In recent years, electrical impedance tomography has widely been used in stroke detection. To improve the prediction accuracy and anti-noise ability of the system, the inverse problem of electrical impedance tomography needs to be solved, for which cascade convolutional neural networks are used. The proposed network is divided into two parts so that the advantages can be compounded when parts of a network are cascaded together. To get high-resolution imaging, an optimized network based on encoding and decoding is designed in the first part. The second part is composed of a residual module, which is used to extract the characteristics of voltage information and ensure that no information is lost. The anti-noise performance of the network is better than other networks. In physical experiments, it is also proved that the algorithm can roughly restore the location of the object in the field.

Abstract
OBJECTIVE Transradial access (TRA) provides a more direct entry to posterior circulation system for endovascular therapy compared to transfemoral access (TFA). This meta-analysis aims to evaluate the safety and feasibility of TRA in neurointervention of posterior circulation. MATERIALS AND METHODS A systematic search was conducted in the Wanfang Data, CBM, PubMed, Embase, Cochrane Library, Web of Science databases. The primary outcomes included total complications and access site complications. Secondary outcomes were single puncture success, procedural success, access cross-over, catheter retention time and fluoroscopy time. RESULTS Six studies encompassing 297 patients were included in the meta-analysis. Compared to the TFA group, the TRA group showed significantly decreased total complications (odds ratio [OR] = 0.29, 95% confidence interval [CI] [0.12, 0.73], p < 0.01) and access site complications (OR = 0.19, 95%CI [0.06, 0.62], p < 0.01), yet it had a longer catheter retention time (mean difference [MD] = 0.80, 95%CI [0.60, 1.00], p < 0.01). There were no significant differences in single puncture success (OR = 3.68, 95%CI[0.38, 35.86], p = 0.26), procedural success (OR = 0.30,95%CI [0.05, 1.73], p = 0.18), access cross-over (OR = 2.29, 95%CI [0.19, 28.26], p = 0.52), fluoroscopy time (MD = 0.97, 95%CI [- 0.91, 2.84], p = 0.31) between the TRA and TFA groups. CONCLUSION This meta-analysis demonstrated that TRA is a safe and feasible alternative to TFA for neurointervention in the posterior circulation. TRA showed significantly decreased total complications and access site complications, yet it had a longer catheter retention time than TFA.

Abstract
The subalpine shrub zone of the Qilian Mountains is an important water-retaining area, and it is crucial to clarify the processes of its hydrological cycle. Therefore, based on the stable isotope values of different water bodies in the subalpine shrub zone of the eastern Qilian Mountains from May to October 2019, the characteristics of δD and δ18O of different water bodies and their hydraulic relationships with each other were studied. The results showed that the stable isotope values of precipitation exhibited the largest fluctuations, while they were the most stable for groundwater. Plant transpiration was stronger than the evaporation of other water bodies. The stable isotope of precipitation was enriched in high temperature and low humidity environments. Isotopic values of plant and soil water were higher and more stable on the semi-sunny slope than on the semi-shady slope. According to the stable isotopes, there was a strong hydraulic relationship between the different water bodies in the study area, and precipitation was the ultimate source of all of them. Precipitation replenished soil water through infiltration. Part of the soil water was absorbed by plants, while the rest continued to infiltrate to replenish groundwater. Groundwater and precipitation replenished the river water.

Abstract
Artesunate (ART), an antimalarial drug with a multifunctional immunomodulatory effect, reduces psoriasis disease. ART can alleviate psoriasis-like dermatitis in mice but has no effect on proinflammatory cytokines in the blood. Thus, we hypothesized that the skin might be the target tissue of ART during the treatment of psoriasis. The interleukin (IL)-23/IL-17 axis has a key role in the pathogenesis of psoriasis. However, whether and how ART manipulates the IL-23 signal during psoriasis is unknown. This study found that IL-23 is highly expressed in the epidermis of psoriasis lesions and positively correlated with histological neutrophil infiltration and clinical psoriasis area and severity index (PASI) scores. Furthermore, ART inhibits the migration and cell cycle, as well as tumor necrosis factor-alpha (TNF-α)-induced IL-23 expression in HaCaT cells in a dose-dependent manner, probably through interference with the nuclear factor kappa B (NF-κB) signalling pathway. Animal experiments in imiquimod (IMQ)-induced psoriasis-like mice model also suggested that ART dose-dependently reduces IL-23 in the epidermis and ameliorates neutrophil infiltration. These findings thus provide further molecular evidence supporting ART as a promising drug for psoriasis in clinic.

Abstract
OBJECTIVES The present study sought to compare postoperative bleeding and renal function in patients with multivessel coronary artery disease undergoing simultaneous hybrid coronary revascularization (HCR) and minimally invasive direct off-pump coronary artery bypass grafting (MIDCABG). METHODS The study retrospectively collected the data of 594 consecutive patients who underwent simultaneous HCR and 351 patients who underwent MIDCABG with planned staged HCR (MIDCABG first, then elective percutaneous coronary intervention) in Fuwai Hospital from June 2007 to December 2020. A total of 317 pairs of patients who were matched in a 1:1 ratio with propensity score matching were enrolled in this study. Bleeding and changes in renal function were compared between the 2 groups. RESULTS Compared with patients who underwent MIDCABG, patients who underwent simultaneous HCR had significantly greater chest tube drainage on the day of the operation (492.7 ± 282.4 mL vs 441.0 ± 261.9 mL; P = .023), but no significant difference was detected in the total amount during the postoperative period (788.8 ± 458.9 mL vs 753.3 ± 409.8 mL; P = .74). The differences in re-exploration for bleeding (0.3% vs 1.6%; P = .13), blood transfusion (18.9% vs 16.4%; P = .13), acute kidney injury (23.3% vs 18.6%; P = .53), and in-hospital major adverse cardiovascular and cerebrovascular events (including all-cause death, myocardial infarction, stroke, and repeated revascularization) (2.5% vs 1.9%; P = .67) between the 2 groups did not reach statistical significance. CONCLUSIONS Compared with MIDCABG, simultaneous HCR (MIDCABG first, instant percutaneous coronary intervention) did not increase postoperative bleeding or the incidence of acute kidney injury.

Abstract
We report the results of GUIDANCE-01 (NCT04025593), a randomized, phase II trial of R-CHOP alone or combined with targeted agents (R-CHOP-X) guided by genetic subtyping of newly diagnosed, intermediate-risk, or high-risk diffuse large B cell lymphoma (DLBCL). A total of 128 patients were randomized 1:1 to receive R-CHOP-X or R-CHOP. The study achieved the primary endpoint, showing significantly higher complete response rate with R-CHOP-X than R-CHOP (88% vs. 66%, p = 0.003), with overall response rate of 92% vs. 73% (p = 0.005). Two-year progression-free survival rates were 88% vs. 63% (p < 0.001), and 2-year overall survival rates were 94% vs. 77% (p = 0.001). Meanwhile, post hoc RNA-sequencing validated our simplified genetic subtyping algorithm and previously established lymphoma microenvironment subtypes. Our findings highlight the efficacy and safety of R-CHOP-X, a mechanism-based tailored therapy, which dually targeted genetic and microenvironmental alterations in patients with newly diagnosed DLBCL.

Abstract
Microwave imaging is one of the rapidly developing frontier disciplines in the field of modern medical imaging. The development of microwave imaging algorithms for reconstructing stroke images is discussed in this paper. Compared with traditional stroke detection and diagnosis techniques, microwave imaging has the advantages of low price and no ionizing radiation hazards. The research hotspots of microwave imaging algorithms in the field of stroke are mainly reflected in the design and improvement of microwave tomography, radar imaging, and deep learning imaging. However, the current research lacks the analysis and combing of microwave imaging algorithms. In this paper, the development of common microwave imaging algorithms is reviewed. The concept, research status, current research hotspots and difficulties, and future development trends of microwave imaging algorithms are systematically expounded. The microwave antenna is used to collect scattered signals, and a series of microwave imaging algorithms are used to reconstruct the stroke image. The classification diagram and flow chart of the algorithms are shown in this Figure. (The classification diagram and flow chart are based on the microwave imaging algorithms.).

Abstract
This paper aims to investigate the effects and mechanisms of adipose-derived stem cells-exosomes(ADSCs-exos) toge-ther with aucubin in protecting human-derived nucleus pulposus cells(NPCs) from inflammatory injury, senescence, and apoptosis. The tert-butyl hydroperoxide(TBHP)-induced NPCs were assigned into normal, model, aucubin, ADSCs-exos, and aucubin+ADSCs-exos groups. The cell viability was examined by cell counting kit-8(CCK-8), cell proliferation by EdU staining, cell senescence by senescence-associated-β-galactosidase(SA-β-Gal), and cell cycle and apoptosis by flow cytometry. Enzyme-linked immunosorbent assay was employed to examine the expression of interleukin-1β(IL-1β), IL-10, and tumor necrosis factor-α(TNF-α). Real-time fluorescence quantitative PCR and Western blot were employed to determine the mRNA and protein levels of aggregated proteoglycan(aggrecan), type Ⅱ collagen alpha 1(COL2A1), Toll-like receptor 4(TLR4), and nuclear factor-kappa B(NF-κB). The results showed that compared with the model group, the aucubin or ADSCs-exos group showed enhanced viability and proliferation of NPCs, decreased proportion of G_0/G_1 phase cells, increased proportion of S phase cells, reduced apoptosis and proportion of cells in senescence, lowered IL-1β and TNF-α levels, elevated IL-10 level, down-regulated mRNA and protein levels of TLR4 and NF-κB, and up-regulated mRNA and protein levels of aggrecan and COL2A1. Compared with the aucubin or ADSCs-exos group, the aucubin+ADSCs-exos combination further increased the viability and proliferation of NPCs, decreased the proportion of G_0/G_1 phase cells, increased the proportion of S phase cells, reduced the apoptosis and proportion of cells in senescence, lowered the IL-1β and TNF-α levels, elevated the IL-10 level, down-regulated the mRNA and protein levels of TLR4 and NF-κB, and up-regulated the mRNA and protein levels of aggrecan and COL2A1. In summary, both aucubin and ADSCs-exos could exert protective effects by inhibiting inflammatory responses, reducing apoptosis and senescence of NPCs, improving cell viability and proliferation as well as extracellular matrix synthesis, which may be associated with the inhibition of TLR4/NF-κB signaling pathway activation. The combination of both plays a synergistic role in the protective effects.

Abstract
Chaenomeles speciosa (2n = 34), a medicinal and edible plant in the Rosaceae, is commonly used in traditional Chinese medicine. To date, the lack of genomic sequence and genetic studies has impeded efforts to improve its medicinal value. Herein, we report the use of an integrative approach involving PacBio HiFi (third-generation) sequencing and Hi-C scaffolding to assemble a high-quality telomere-to-telomere genome of C. speciosa. The genome comprised 650.4 Mb with a contig N50 of 35.5 Mb. Of these, 632.3 Mb were anchored to 17 pseudo-chromosomes, in which 12, 4, and 1 pseudo-chromosomes were represented by a single contig, two contigs, and four contigs, respectively. Eleven pseudo-chromosomes had telomere repeats at both ends, and four had telomere repeats at a single end. Repetitive sequences accounted for 49.5% of the genome, while a total of 45 515 protein-coding genes have been annotated. The genome size of C. speciosa was relatively similar to that of Malus domestica. Expanded or contracted gene families were identified and investigated for their association with different plant metabolisms or biological processes. In particular, functional annotation characterized gene families that were associated with the biosynthetic pathway of oleanolic and ursolic acids, two abundant pentacyclic triterpenoids in the fruits of C. speciosa. Taken together, this telomere-to-telomere and chromosome-level genome of C. speciosa not only provides a valuable resource to enhance understanding of the biosynthesis of medicinal compounds in tissues, but also promotes understanding of the evolution of the Rosaceae.

Abstract
Low-dimensional organic-inorganic hybrid perovskites (OIHPs) with broadband emission attract immense scientific interest due to their potential application for the next generation of solid-state lighting. However, due to low exciton utilization, organic cations generally adjust structure rather than contribute the band edge to affect optical properties. Based on this, OIHPs are usually allowed to obtain a low photoluminescence quantum yield (PLQY). Herein, a good charge transfer carrier (p-phenylenediamine, PPDA) as organic cation is rationally employed and a novel indium-based perovskite is synthesized. By coupling with H2 O molecules, a strong interaction between organic and inorganic components is realized by hydrogen bonding, which has good transportability and greatly improves the exciton utilization. The regions of hydrogen bonding show high electron mobility, combined with the induced recombination center, improving the progress of charge relaxation. As a result, the regulation of hydrogen bond strength based on the microstructure optimization directly determines the optical emission intensity, realizing nearly 100% PLQY. Further, the polyhydrogen bond structure makes each component a stronger interaction, showing high stability in polar, organic, and acidic solvent, as well as long-term storing, which represents one of the highest overall performances for lighting in OIHPs.

Abstract
OBJECTIVES To investigate the challenges of patients with spinal muscular atrophy (SMA) during the Omicron variant COVID-19 pandemic. DESIGN A cross-sectional survey was conducted in China from January 02, 2023, to January 12, 2023, using a questionnaire that covered three aspects: (1) Demographic information; (2) SMA-related information; and (3) COVID-19-related information. We recruited patients with SMA from 33 provinces. The prevalence, course, and clinical manifestations of COVID-19 were calculated. The relationships between independent and outcome variables were investigated. RESULTS In total, 677 patients (male: 349; female: 328) were included in this study (average age = 11.40 years); 534 (78.88%) suffered from COVID-19. The most common symptoms were fever (95.51%), cough (57.87%), and sputum (49.44%). Of the infected patients, 91.57% recovered with at-home care, and 8.43% were hospitalized; 1.31% were admitted to the intensive care unit (ICU). A positive correlation was observed between the SMA severity and hospitalization rate. The ICU stay rate in patients with SMA type I was significantly higher than that in other SMA types. CONCLUSION This is the first large sample survey to timely reveal the living situation of patients with SMA during the COVID-19 pandemic's Omicron variant. Patients with SMA type I should be paid more attention in terms of hospitalization and ICU stay.

Abstract
Neutral lipid-storage disease with myopathy (NLSDM) is an autosomal recessive neuromuscular disorder caused by mutations in PNPLA2, and the average age at onset is 30 years. To date, only eight patients with childhood-onset NLSDM have been reported in detail. We investigated 3 unreported patients with NLSDM detected in childhood and reviewed 8 childhood-onset and 82 adult-onset patients with NLSDM documented in the literature. In the childhood-onset cohort, NLSDM presented initially as asymptomatic or paucisymptomatic hyperCKemia in 6/11 patients, and follow-up data showed onset of muscle weakness in 6/11 childhood-onset patients. In the adult-onset cohort, 95.1% (78/82) of patients showed muscle weakness. Cardiac involvement developed in 6/11 childhood-onset patients. Hepatomegaly was observed in 3/11 childhood-onset patients. Serum creatine kinase levels were elevated greater than five-fold of the upper limit of normal (ULN) in most childhood-onset patients and were elevated to less than ten-fold of the ULN in most adult-onset patients. Peripheral blood smears and muscle biopsies showed cytoplasmic lipid droplets in leukocytes and myocytes. NLSDM can present in children with asymptomatic or paucisymptomatic hyperCKemia before the onset of muscle weakness. The presence of lipid droplets in leucocytes (Jordans' anomaly) aids in diagnosing and confirming the pathogenicity of PNPLA2 variants of uncertain significance. There were no clear genotype-phenotype correlations in patients with NLSDM.

Abstract
OBJECTIVES Mitochondrial diabetes mellitus is caused by dysfunctional mitochondria and is often misdiagnosed because of its various clinical manifestations. It's even rarer in children, and without a clear family history of diabetes with hearing loss, it's often difficult to diagnose. CASE PRESENTATION This is a case study of a family with maternally inherited diabetes mellitus and deafness (MIDD). The proband was an adolescent girl with diabetes with a family history of type 2 diabetes (T2DM) for three generations. Family members have undetected hearing impaired. The proband could not be diagnosed with type 1 diabetes (T1DM) or T2DM. Therefore, whole exome and mitochondrial gene sequencing was performed, which identified an m.3243A>G mutation in the mitochondrial DNA. CONCLUSIONS This suggests that we should be alert to the possibility of hereditary diabetes, especially mitochondrial diabetes in patients with atypical diabetes. A thorough physical examination is very important. What is new: (1) Mitochondrial diabetes in childhood may not be accompanied by deafness even with highly heteroplasmy levels. (2) In MIDD patients, sometimes hearing loss cannot be perceived, which requires us to conduct detailed physical examinations and related examinations. (3) The use of metformin in MIDD patients did not have adverse consequences.

Abstract
OBJECTIVE To explore prevalence, risk factors and treatment of ankle sprain of young college student , in order to obtain accurate epidemiological data. METHODS From March 2019 to May 2019, 552 college students(1 104 sides of anke joints) from Xi'an Physical Education university were enrolled in study according to inclusion and excludion standard, including 309 males and 243 females aged from 16 to 24 years old with an average of (20.9±3.7) years old. Age, gender, and body mass indes(BMI) etc were recorded. Morbidity of acute and chronic ankle sprains of physical students, treatment after the first sprain (cold compress, cast or plaster bracing and medicine), visual analogue scale (VAS) during walking were assessed through ankle sprain questionnaire;Cumberland ankle instability tool (CAIT), Maryland foot score were applied to assess ankle function. Lateral ankle ligament injury was objectively assessed by musculoskeletal ultrasonography. RESULTS The prevalence of acute ankle sprain(AAS) was 96.20% (531/552), and the incidence of AAS was 59.96% (622/1 104). The prevalence of chronic ankle joint instability(CAI) was 16.85% (93/552), and the incidence of CAI was 8.97% (99/1 104). In the four categories of sports, college student suffered from multiple sprains in performance majors group was 22.20% (14/63), including of aerobicsand dance performance. The incidence of AAS of ball sports was 8.60%(14/163). After the first sprain, most college students(94.4%) were received cold compression, about 60% of them went to hospital;however, only 44.7% students were received standard treatmens(cast or plaster), only 35.3% of them were received hard ankle orthosis. In 552 college students, 44 students were suffered from more than 4 times of ankle sprain, and the total incidence was 7.97% (44/552). Cumberland score was 26.6±2.4, Cumberland score of students sprained ankle joint more than 4 times was (29.2±1.1), suggested it was a risk factor for ankle joint instability. VAS of students sprained ankle joint more than 4 times was higher than that of less than 4 times(P<0.05), Maryland foot score was significantly lower than that of that of <4 times(P<0.05). Musculoskeletal ultrasonography measured the thickness of anterior tibiofibular ligament(ATFL) was (2.41±0.41) mm, and the thickness of calcaneofibular ligament(CFL) was (1.92±0.21) mm, and had no statistical difference(P>0.05). CONCLUSION Ninty-four percent college students had at least once ankle sprain, ankle sprains were more common in erobics and ball sports. After the first sprain, the proportion of cast or plaster treatment was less than 50%. Sprained ankle joint more than 4 times is a risk factor, and musculoskeletal ultrasonography showed thickening of both ATFL and CFL, while no statstical difference.

Abstract
The globally coordinated motion produced by the classical swarm model is typically generated by simple local interactions at the individual level. Despite the success of these models in interpretation, they cannot guarantee compact and ordered collective motion when applied to the cooperation of unmanned aerial vehicle (UAV) swarms in cluttered environments. Inspired by the behavioral characteristics of biological swarms, a distributed self-organized Reynolds (SOR) swarm model of UAVs is proposed. In this model, a social term is designed to keep the swarm in a collision-free, compact, and ordered collective motion, an obstacle avoidance term is introduced to make the UAV avoid obstacles with a smooth trajectory, and a migration term is added to make the UAV fly in a desired direction. All the behavioral rules for agent interactions are designed with as simple a potential function as possible. And the genetic algorithm is used to optimize the parameters of the model. To evaluate the collective performance, we introduce different metrics such as (a) order, (b) safety, (c) inter-agent distance error, (d) speed range. Through the comparative simulation with the current advanced bio-inspired compact and Vasarhelyi swarm models, the proposed approach can guide the UAV swarm to pass through the dense obstacle environment in a safe and ordered manner as a compact group, and has adaptability to different obstacle densities.

Abstract
Low-dimensional perovskites (LDPs) have enormous potential for the development of advanced optoelectronic devices and tackling the stability issue for the commercial application of perovskites. However, quantified structural dimensionality prediction for LDPs is still an intractable issue. Herein, we develop a self-established machine learning (ML)-assisted approach to predict the dimensionality of LDPs based on 195 reported amines that are classified as two-dimensional, one-dimensional, and zero-dimensional. The optimal K-nearest neighbor model allows us to realize an accuracy rate of 92.3% for the test data set containing 39 reported amines. Two features, i.e., ATSC1pe and SlogP_VSA2, associated with polarity and electrostatic potential on the van der Waals surface of an organic spacer, are identified from >1800 descriptors as key controlling factors determining the structure dimensionality. This work develops a typical paradigm for the application of a multiple-classification strategy of ML with an extremely high accuracy rate, which would thereby motivate the development of new types of LDPs.

Abstract
Developing stable cathode materials that are resistant to storage degradation is essential for practical development and industrial processing of Na-ion batteries as many sodium layered oxide materials are susceptible to hygroscopicity and instability upon exposure to ambient air. Among the various layered compounds, Fe-substituted O3-type Na(Ni1/2Mn1/2)1-xFexO2 materials have emerged as a promising option for high-performance and low-cost cathodes. While previous reports have noted the decent air-storage stability of these materials, the role and origin of Fe substitution in improving storage stability remain unclear. In this study, we investigate the air-resistant effect of Fe substitution in O3-Na(Ni1/2Mn1/2)1-xFexO2 cathode materials by performing systematic surface and structural characterizations. We find that the improved storage stability can be attributed to the multifunctional effect of Fe substitution, which forms a surface protective layer containing an Fe-incorporated spinel phase and decreases the thermodynamical driving force for bulk chemical sodium extraction. With these mechanisms, Fe-containing cathodes can suppress the cascades of cathode degradation processes and better retain the electrochemical performance after air storage.

Abstract
Programed cell death protein-1 (PD-1) inhibitor, apatinib, and chemotherapy show synergistic antitumor effect in gastric cancer. This study aimed to evaluate this combination as a neoadjuvant therapy in locally advanced gastric cancer (LAGC). In this retrospective study, data from 179 LAGC patients who underwent neoadjuvant therapy with a PD-1 inhibitor plus apatinib and chemotherapy (PAC group, n=56), apatinib and chemotherapy (AC group, n=50), or chemotherapy alone (C group, n=73) were analyzed. The PAC group displayed a numerically higher radiologic objective response rate than the AC group (73.2% vs. 60.0%, P=0.149) and significantly higher than the C group (73.2% vs. 35.6%, P<0.001). Tumor resection rates between the PAC and AC groups were not significantly different (100.0% vs. 94.0%, P=0.102) but were higher in the PAC group compared to the C group (100.0% vs. 89.0%, P=0.010). Pathological evaluations revealed comparable R0 resection rates across all groups (P=0.873) and a non-significantly higher pathological complete response rate in the PAC group compared to the AC group (26.8% vs. 17.0%, P=0.236), while significantly higher than the C group (26.8% vs. 7.7%, P=0.005). Moreover, the PAC group exhibited a longer progression-free survival compared to the AC (P=0.036) and C (P<0.001) groups, an extended disease-free survival compared to the C group (P=0.002), and improved overall survival compared to the AC (P=0.028) and C (P=0.002) groups. Adverse events were generally comparable, with the highest incidence of peripheral neuropathy observed in the PAC group (26.8%, P=0.020). PD-1 inhibitor plus apatinib and chemotherapy may represent an effective neoadjuvant regimen for LAGC management, necessitating further validation.

Abstract
Neuropathic pain(NP) has similar phenotypes but different sequential neuroinflammatory mechanisms in the pathological process. It is of great significance to inhibit the initiation of neuroinflammation, which has become a new direction of NP treatment and drug development in recent years. Mongolian drug Naru-3 is clinically effective in the treatment of trigeminal neuralgia, sciatica, and other NPs in a short time, but its pharmacodynamic characteristics and mechanism of analgesia are still unclear. In this study, a spinal nerve ligation(SNL) model simulating clinical peripheral nerve injury was established and the efficacy and mechanism of Naru-3 in the treatment of NPs was discussed by means of behavioral detection, side effect evaluation, network analysis, and experimental verification. Pharmacodynamic results showed that Naru-3 increased the basic pain sensitivity threshold(mechanical hyperalgesia and thermal radiation hyperalgesia) in the initiation of SNL in animals and relieved spontaneous pain, however, there was no significant effect on the basic pain sensitivity threshold and motor coordination function of normal animals under physiological and pathological conditions. Meanwhile, the results of primary screening of target tissues showed that Naru-3 inhibited the second phase of injury-induced nociceptive response of formalin test in mice and reduced the expression of inflammatory factors in the spinal cord. Network analysis discovered that Naru-3 had synergy in the treatment of NP, and its mechanism was associated with core targets such as matrix metalloproteinase-9(MMP9) and interleukin-1β(IL-1β). The experiment further took the dorsal root ganglion(DRG) and the stage of patho-logical spinal cord as the research objects, focusing on the core targets of inducing microglial neuroinflammation. By means of Western blot, immunofluorescence, agonists, antagonists, behavior, etc., the mechanism of Naru-3 in exerting NP analgesia may be related to the negative regulation of the MMP9/IL-1β signaling pathway-mediated microglia p38/IL-1β inflammatory loop in the activation phase. The relevant research enriches the biological connotation of Naru-3 in the treatment of NP and provides references for clinical rational drug use.

Abstract
This study assessed the modification effects of zirconia-based nanopowder and cement contents and curing age on the mechanical properties of silty soil. The orthogonal test design was applied to derive the best combination of each influencing factor using the lateral unconfined compressive test. Two-dimensional particle flow code (PFC2D) distinct-element modeling software was also used to fit and analyze the test curves, as well as simulate the triaxial test with the derived parameters. The test results reveal the optimal combination of 20% cement, 2% zirconia-based nanopowder, and 28 d curing age. The extreme difference table was used to plot the orthogonal trend diagram, and cement content was found to be the most significant factor controlling the silty soil strength. The maximum peak stress was 2196.33 kPa under the optimum combination of factors, which could be obtained through the index estimation, and these results were experimentally verified. According to the predicted strength envelope, the cohesive force of nanopowder-cement-modified silty soil in the optimal proportion was 717.11 kPa, and the internal friction angle was 21.05°. Nano zirconium dioxide will accelerate the hydration reaction of cement, the flocculent structure produced by the hydration of cement and soil particles connected to each other, play the role of filling and anchoring, and thus increase the strength of the nano-zirconium dioxide, and the optimal dosage of nano-zirconium dioxide is 2%.

Abstract
Solid-electrolyte interphases (SEIs) in advanced rechargeable batteries ensure reversible electrode reactions at extreme potentials beyond the thermodynamic stability limits of electrolytes by insulating electrons while allowing the transport of working ions. Such selective ion transport occurs naturally in biological cell membranes as a ubiquitous prerequisite of many life processes and a foundation of biodiversity. In addition, cell membranes can selectively open and close the ion channels in response to external stimuli (e.g., electrical, chemical, mechanical, and thermal), giving rise to "gating" mechanisms that help manage intracellular reactions. We wondered whether the chemistry and structure of SEIs can mimic those of cell membranes, such that ion gating can be replicated. That is, can SEIs realize a reversible switching between two electrochemical behaviors, i.e., the ion intercalation chemistry of batteries and the ion adsorption of capacitors? Herein, we report such SEIs that result in thermally activated selective ion transport. The function of open/close gate switches is governed by the chemical and structural dynamics of SEIs under different thermal conditions, with precise behaviors as conducting and insulating interphases that enable battery and capacitive processes within a finite temperature window. Such an ion gating function is synergistically contributed by Arrhenius-activated ion transport and SEI dissolution/regrowth. Following the understanding of this new mechanism, we then develop an electrochemical method to heal the SEI layer in situ. The knowledge acquired in this work reveals the possibility of hitherto unknown biomimetic properties of SEIs, which will guide us to leverage such complexities to design better SEIs for future battery chemistries.

Abstract
Purpose Osteoarthritis (OA) is a common clinical disease characterized by the destruction of articular cartilage, subchondral ossification, cystic degeneration and osteophyte formation. Recently, more and more scholars draw attention to exosomes in the field of OA, and exciting breakthroughs have been achieved in recent years. However, bibliometric analysis of the literature in this research field is lacking. Considering its potential in treatment of OA, this article aimed to analyze the research status and identify future hotspots of exosomes in osteoarthritis in recent 10 years by bibliometrics tools. Methods Relevant publications in this field from 2012 to 2022 was retrieved from the Web of Science core collection database (WOSSCC). And we used Vosviewers, CiteSpace, an online analysis platform and the R package "Bibliometrix" for bibliometric analysis. Results A total of 484 publications (including 319 articles and 165 reviews) from 51 countries, 720 institutions, were included in this study. IRCCS Ist Ortoped Galeazzi, Shanghai Jiao Tong University, and Sun Yat-sen University are the leading research institutions in this field. International Journal of Molecular Sciences contributed the largest number of articles, and Osteoarthritis and Cartilage is the most co-cited journal. Of the 2664 scholars who participated in the study, Ragni E, De Girolamo L, Orfei CP, and Colombini A had the largest number of articles. Zhang, SP is the most co-cited author. "Mesenchymal stem cell", "biomaterials", "Inflammation" and "regenerative medicine" are the keywords in the research. Conclusion This is the first bibliometric analysis of exosomes in osteoarthritis. We explored current research status in recent years and identified frontiers and hot spots in this research field. We highlight the significant roles of mesenchymal stem cell-derived exosomes (MSC-Exos) in the treatment of osteoarthritis, and identified exosomal biomaterials as frontier in this research domain, which can provide reference for the researchers who focus on this research field.

Abstract
Objective Diagnosis classification and risk stratification are crucial in the prognosis prediction and treatment selection of acute myeloid leukemia (AML). Here, we used a database of 536 AML patients to compare the 4th and 5th WHO classifications and the 2017 and 2022 versions of ELN guidance. Methods AML patients were classified according to the 4th and 5th WHO classifications, as well as the 2017 and 2022 versions of the European LeukemiaNet (ELN) guidance. Kaplan-Meier curves with log-rank tests were used for survival analysis. Results The biggest change was that 25 (5.2%), 8 (1.6%), and 1 (0.2%) patients in the AML, not otherwise specified (NOS) group according to the 4th WHO classification, were re-classified into the AML-MR (myelodysplasia-related), KMT2A rearrangement, and NUP98 rearrangement subgroups based on the 5th WHO classification. Referring to the ELN guidance, 16 patients in the favorable group, six patients in the adverse group, and 13 patients in the intermediate group based on the 2017 ELN guidance were re-classified to the intermediate and adverse groups based on the 2022 ELN guidance. Regrettably, the Kaplan-Meier curves showed that the survival of intermediate and adverse groups could not be distinguished well according to either the 2017 or 2022 ELN guidance. To this end, we constructed a risk model for Chinese AML patients, in which the clinical information (age and gender), gene mutations (NPM1, RUNX1, SH2B3, and TP53), and fusions (CBFB::MYH11 and RUNX1::RUNX1T1) were included, and our model could help divide the patients into favorable, intermediate, and adverse groups. Conclusion These results affirmed the clinical value of both WHO and ELN, but a more suitable prognosis model should be established in Chinese cohorts, such as the models we proposed.

Abstract
BACKGROUND Autism spectrum disorders (ASD) are a group of neurodevelopmental disorders characterized by difficulty communicating with society and others, behavioral difficulties, and a brain that processes information differently than normal. Genetics has a strong impact on ASD associated with early onset and distinctive signs. Currently, all known ASD risk genes are able to encode proteins, and some de novo mutations disrupting protein-coding genes have been demonstrated to cause ASD. Next-generation sequencing technology enables high-throughput identification of ASD risk RNAs. However, these efforts are time-consuming and expensive, so an efficient computational model for ASD risk gene prediction is necessary. RESULTS In this study, we propose DeepASDPerd, a predictor for ASD risk RNA based on deep learning. Firstly, we use K-mer to feature encode the RNA transcript sequences, and then fuse them with corresponding gene expression values to construct a feature matrix. After combining chi-square test and logistic regression to select the best feature subset, we input them into a binary classification prediction model constructed by convolutional neural network and long short-term memory for training and classification. The results of the tenfold cross-validation proved our method outperformed the state-of-the-art methods. Dataset and source code are available at https://github.com/Onebear-X/DeepASDPred is freely available. CONCLUSIONS Our experimental results show that DeepASDPred has outstanding performance in identifying ASD risk RNA genes.

Abstract
Inflammation-related diseases affect large populations of people in the world and cause substantial healthcare burdens, which results in significant costs in time, material, and labor. Preventing or relieving uncontrolled inflammation is critical for the treatment of these diseases. Herein, we report a new strategy for alleviating inflammation by macrophage reprogramming via targeted reactive oxygen species (ROS) scavenging and cyclooxygenase-2 (COX-2) downregulation. As a proof of concept, we synthesize a multifunctional compound named MCI containing a mannose-based macrophage targeting moiety, an indomethacin (IMC)-based segment for inhibiting COX-2, and a caffeic acid (CAF)-based section for ROS clearance. As revealed by a series of in vitro experiments, MCI could significantly attenuate the expression of COX-2 and the level of ROS, leading to M1 to M2 macrophage reprogramming, as evidenced by the reduction and the elevation in the levels of pro-inflammatory M1 markers and anti-inflammatory M2 markers, respectively. Furthermore, in vivo experiments show MCI's promising therapeutic effects on rheumatoid arthritis (RA). Our work illustrates the success of targeted macrophage reprogramming for inflammation alleviation, which sheds light on the development of new anti-inflammatory drugs.

Abstract
Decreased estrogen level is one of the main causes of lipid metabolism disorders and coronary heart disease in women after menopause. Exogenous estradiol benzoate is effective to some extent in alleviating lipid metabolism disorders caused by estrogen deficiency. However, the role of gut microbes in the regulation process is not yet appreciated. The objective of this study was to investigate the effects of estradiol benzoate supplementation on lipid metabolism, gut microbiota, and metabolites in ovariectomized (OVX) mice and to reveal the importance of gut microbes and metabolites in the regulation of lipid metabolism disorders. This study found that high doses of estradiol benzoate supplementation effectively attenuated fat accumulation in OVX mice. There was a significant increase in the expression of genes enriched in hepatic cholesterol metabolism and a concomitant decrease in the expression of genes enriched in unsaturated fatty acid metabolism pathways. Further screening of the gut for characteristic metabolites associated with improved lipid metabolism revealed that estradiol benzoate supplementation influenced major subsets of acylcarnitine metabolites. Ovariectomy significantly increased the abundance of characteristic microbes that are significantly negatively associated with acylcarnitine synthesis, such as Lactobacillus and Eubacterium ruminantium group bacteria, while estradiol benzoate supplementation significantly increased the abundance of characteristic microbes that are significantly positively associated with acylcarnitine synthesis, such as Ileibacterium and Bifidobacterium spp. The use of pseudosterile mice with gut microbial deficiency greatly facilitated the synthesis of acylcarnitine due to estradiol benzoate supplementation and also alleviated lipid metabolism disorders to a greater extent in OVX mice. IMPORTANCE Our findings establish a role for gut microbes in the progression of estrogen deficiency-induced lipid metabolism disorders and reveal key target bacteria that may have the potential to regulate acylcarnitine synthesis. These findings suggest a possible route for the use of microbes or acylcarnitine to regulate disorders of lipid metabolism induced by estrogen deficiency.

Abstract
Exploring novel healing mechanisms is a constant impetus for the development of self-healing materials. Herein, we find that side-chain interlocking of bottlebrush polymers can form a dynamic network and thereby serve as a driving force for the self-healing process of the materials. Molecular dynamics simulation indicates that the interlocking is formed by the interpenetration between the long side chains of adjacent molecules and stabilized by van der Waals interactions and molecular entanglements of side chains. The interlocking can be tailored by changing the length and density of the side chains through atom transfer radical polymerization. As a result, the optimized bottlebrush polymer shows a healing efficiency of up to 100%. Unlike chemical interactions, side-chain interlocking eliminates the introduction of specific chemical groups. Therefore, bottlebrush polymers can even self-heal under harsh aqueous conditions, including acid and alkali solutions. Moreover, the highly dynamic side-chain interlocking enables bottlebrush polymers to efficiently dissipate vibration energy, and thus they can be used as damping materials. Collectively, side-chain interlocking expands the scope of physical interactions in self-healing materials and hews out a versatile way for polymers to accomplish self-healing capability in various environments.

Abstract
POMGNT1, encoding protein O-mannose beta-1,2-N-acetylglucosaminyltransferase 1, is one of the genes responsible for dystroglycanopathy (DGP), which includes multiple phenotypes such as muscle-eye-brain disease (MEB), congenital muscular dystrophy with intellectual disability, and limb-girdle muscular dystrophy Here, we report a case of MEB that is the result of a homozygous variant of POMGNT1 that is revealed through uniparental disomy (UPD). An 8-month-old boy was admitted with mental and motor retardation, hypotonia, esotropia, early onset severe myopia, and structural brain abnormalities. A panel testing of genetic myopathy-related genes was used to identify a homozygous c.636C>T (p.Phe212Phe) variant in exon 7 of POMGNT1 in the patient, a heterozygous c.636C>T variant in the father, and the wild type in the mother. Quantitative polymerase chain reaction (q-PCR) revealed no abnormal copy numbers in exon 7. Trio-based whole-exome sequencing (trio-WES) revealed a possible paternal UPD on chromosome 1 of the patient. Chromosomal microarray analysis (CMA) revealed a 120,451 kb loss of heterozygosity (LOH) on 1p36.33-p11.2, encompassing POMGNT1, and a 99,319 kb loss of heterozygosity on 1q21.2-q44, which indicated UPD. Moreover, RNA sequencing (RNA-seq) verified that the c.636C>T variant was a splice-site variant, leading to skipping of exon 7 (p.Asp179Valfs*23). In conclusion, to the best of our knowledge, we present the first case of MEB caused by UPD, providing valuable insights into the genetic mechanisms underlying this condition.

Abstract
It has been reported that DEP domain protein 1B (DEPDC1B) serves several roles in the occurrence and development of various types of cancer. Nevertheless, the effect of DEPDC1B on colorectal cancer (CRC), as well as its particular underlying molecular mechanism remain to be elucidated. In the present study, the mRNA and protein expression levels of DEPDC1B and nucleoporin 37 (NUP37) in CRC cell lines were assessed by reverse transcription‑quantitative PCR and western blotting, respectively. Cell Counting Kit‑8 and 5‑Ethynyl‑2'‑deoxyuridine assays were carried out to determine cell proliferation. In addition, the migration and invasion abilities of cells were evaluated using wound healing and Transwell assays. The changes in cell apoptosis and cell cycle distribution were assessed by flow cytometry and western blotting. Bioinformatics analysis and co‑immunoprecipitation assays were performed to predict and verify, respectively, the binding capacity of DEPDC1B on NUP37. The expression levels of Ki‑67 were detected by immunohistochemical assay. Finally, the activation of phosphoinositide 3‑kinase (PI3K)/protein kinase B (AKT) signaling was measured using western blotting. The results showed that DEPDC1B and NUP37 were upregulated in CRC cell lines. DEPDC1B and NUP37 silencing both inhibited the proliferation, migration and invasion capabilities of CRC cells and promoted cell apoptosis and cell cycle arrest. Furthermore, NUP37 overexpression reversed the inhibitory effects of DEPDC1B silencing on the behavior of CRC cells. Animal experiments demonstrated that DEPDC1B knockdown inhibited the growth of CRC in vivo by targeting NUP37. In addition, DEPDC1B knockdown inhibited the expression levels of the PI3K/AKT signaling‑related proteins in CRC cells and tissues by also binding to NUP37. Overall, the current study suggested that DEPDC1B silencing could alleviate the progression of CRC via targeting NUP37.

Abstract
Although cytotoxic treatments hold tremendous potential in boosting antitumor immunity, efferocytosis of tumor-associated macrophages (TAMs) could negatively remove apoptotic tumor cells through LC3-associated phagocytosis (LAP), resulting in inefficient tumor antigen presentation and immunosuppressive tumor microenvironment. To address this issue, we developed TAM-targeting nanospores (PC-CW) inspired by the predominant tropism of Rhizopus oryzae toward macrophages. To construct PC-CW, we disguised poly(sodium-p-styrenesulfonate) (PSS)-coated polyethylenimine (PEI)-shRNA nanocomplexes with the cell wall of R. oryzae conidia. LAP blockade by PC-CW delayed the degradation of engulfed tumor debris within TAMs, which not only enhanced antigen presentation but also initiated the domino effect of the antitumor immune response through STING signaling and TAM repolarization. Benefiting from this, PC-CW successfully sensitized the immune microenvironment and amplified CD8+ T cell responses following chemo-photothermal therapy, leading to substantial tumor growth control and metastasis prevention in tumor-bearing mouse models. The bioengineered nanospores represent a simple and versatile immunomodulatory strategy targeting TAMs for robust antitumor immunotherapy.

Abstract
Thorium, as a radioactive element, is always associated with rare earth in nature. So it is an exacting challenge to recognize thorium ion (Th4+) in the presence of lanthanide ions because of their overlapping ionic radii. Here three simple acylhydrazones (AF, AH and ABr, with the functional group fluorine, hydrogen and bromine, respectively) are explored for Th4+ detection. They all exhibit excellent "turn-on" fluorescence selectivity toward Th4+ among f-block ions in aqueous medium with outstanding anti-interference abilities, where the coexistence of lanthanide and uranyl ions in addition with other ordinary metal ions have negligible effects during Th4+ detection. Interestingly, pH variation from 2 to 11 has no significant influence on the detection. Among the three sensors, AF displays the highest sensitivity to Th4+ and ABr the lowest with the emission wavelengths in the order of λAF-Th < λAH-Th < λABr-Th. The detection limit of AF to Th4+ can reach 29 nM (pH = 2) with a binding constant of 6.64 × 109 M-2. Response mechanism for AF toward Th4+ is proposed based on the results of HR-MS, 1H NMR and FT-IR spectroscopies together with DFT calculations. This work provides important implications on the development of related series of ligands in nuclide ions detection and future separation from lanthanide ions.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The seeds of Entada phaseoloides (Linn.) Merr. commonly named "Ke-teng-zi" is a traditional Chinese folk medicine and reported to treat dermatitis, spasm, and headache. However, the exact effect and the mechanism of Ke-teng-zi on the treatment of dermatitis is unclear. AIM OF THE STUDY To elucidate the antipruritic effect and molecular mechanisms of Ke-teng-zi on the treatment of allergic contact dermatitis (ACD). MATERIALS AND METHODS The main components of the n-butanol fraction of 70% ethanol extract from Ke-teng-zi (abbreviated as KB) were analyzed by HPLC. The chloroquine (CQ)-induced acute itch and squaraine dibutyl ester (SADBE)-induced ACD chronic itch in mice was established, and the TNF-α/IFN-γ stimulated Human keratinocytes (HaCaT) were used to evaluate the antipruritic and anti-inflammatory effects of KB. Behavioral tests, lesion scoring, and histology were also examined. The expression levels of molecules in MAPK and JAK/STAT3 pathways, the mRNA levels of chemokines and cytokines in both the skin of ACD mice and the HaCaT cells were detected by western blot and qPCR. Furthermore, whole-cell patch-clamp recordings in TRPA1-tranfected HEK293T cells were used to elucidate the effect of KB on TRPA1 channels. TRPA1 siRNA was used to evaluate the role of TRPA1 in the anti-inflammatory effect of KB in keratinocytes. RESULTS The main compounds in KB could bind to the active sites of TRPA1 mainly through hydrogen bond and hydrophobic bond interactions. KB could inhibit the scratching behavior in CQ-induced acute itch, and the inhibitory effect of KB was blocked by TRPA1 inhibitor HC-030031. In addition, KB significantly decreased the scratching bouts of ACD mice, reduced the skin lesion scores, mast cells degranulation, and epidermal thickening, inhibited the production of inflammatory chemokines/cytokines and CGRP, and down-regulated the levels of p-ERK1/2, p-p38, and p-STAT3, compared to the ACD mice. Moreover, continuous application of KB induced the desensitization of TRPA1 channels. Also, KB inhibited the expression of p-ERK1/2, p-p38, and p-STAT3, and down-regulated the expression of inflammatory chemokines and cytokines in vitro, which were reversed by the TRPA1 siRNA. CONCLUSIONS KB alleviated the pruritus and skin inflammation in ACD mice through TRPA1 channels desensitization and down-regulation of intracellular MAPK and JAK/STAT3 signaling pathways. Our results suggested that Ke-teng-zi is a potential drug for the treatment of inflammatory skin diseases such as ACD.

Abstract
BACKGROUND More than 50 loci are associated with spinocerebellar ataxia (SCA), and the most frequent subtypes share nucleotide repeats expansion, especially CAG expansion. OBJECTIVE The objective of this study was to confirm a novel SCA subtype caused by CAG expansion. METHODS We performed long-read whole-genome sequencing combined with linkage analysis in a five-generation Chinese family, and the finding was validated in another pedigree. The three-dimensional structure and function of THAP11 mutant protein were predicted. Polyglutamine (polyQ) toxicity of THAP11 gene with CAG expansion was assessed in skin fibroblasts of patients, human embryonic kidney 293 and Neuro-2a cells. RESULTS We identified THAP11 as the novel causative SCA gene with CAG repeats ranging from 45 to 100 in patients with ataxia and from 20 to 38 in healthy control subjects. Among the patients, the number of CAA interruptions within CAG repeats was decreased to 3 (up to 5-6 in controls), whereas the number of 3' pure CAG repeats was up to 32 to 87 (4-16 in controls), suggesting that the toxicity of polyQ protein was length dependent on the pure CAG repeats. Intracellular aggregates were observed in cultured skin fibroblasts from patients. THAP11 polyQ protein was more intensely distributed in the cytoplasm of cultured skin fibroblasts from patients, which was replicated with in vitro cultured neuro-2a transfected with 54 or 100 CAG repeats. CONCLUSIONS This study identified a novel SCA subtype caused by intragenic CAG repeat expansion in THAP11 with intracellular aggregation of THAP11 polyQ protein. Our findings extended the spectrum of polyQ diseases and offered a new perspective in understanding polyQ-mediated toxic aggregation. © 2023 The Authors.

Abstract
The TRNT1 gene encodes tRNA nucleotidyltransferase 1, which catalyzes the addition of cytosine-cytosine-adenosine (CCA) to the ends of cytoplasmic and mitochondrial tRNAs. The most common clinical phenotype associated with TRNT1 is autosomal recessive sideroblastic anemia with B-cell immunodeficiency, periodic fever, and developmental delay (SIFD). Muscle involvement has rarely been reported in TRNT1-related disorders. Here we report a Chinese patient with incomplete SIFD and hyperCKemia, and explored the skeletal muscle pathological changes. The patient was a 3-year-old boy with sensorineural hearing loss, sideroblastic anemia, and developmental delay since infancy. At the age of 11 months, significantly increased levels of creatine kinase were noted, accompanied by mild muscle weakness. Whole-exome sequencing revealed compound heterozygous variants of the TRNT1 gene, c.443C > T (p.Ala148Val) and c.692C > G (p.Ala231Gly), in the patient. Western blot showed a decreased expression of TRNT1 and cytochrome c oxidase subunit IV (COX IV) in the skeletal muscle of the patient. Electron microscopy observation of skeletal muscle pathology revealed abnormal mitochondria of various sizes and shapes, supporting a diagnosis of mitochondrial myopathy. The present case indicates that in addition to the classic SIFD phenotype, TRNT1 mutations can cause mitochondrial myopathy, a rare clinical phenotype of TRNT1-related disorders.

Abstract
Background Insulin resistance has been implicated in the pathogenesis of children born small for gestational age (SGA) with catch-up growth (CUG). Adipose tissue macrophages (ATMs) regulate insulin resistance by secreting exosomes containing microRNA (miRNA) cargo; however, their pathogenic roles and molecular mechanism are not fully understood. This study aimed to investigate the role of miR-210-5p in rats born SGA with CUG and insulin resistance. Methods The dietary needs of pregnant rats were restricted to ensure the birth of SGA rats. Transmission electron microscopy (TEM) and Western blot analysis were used to identify the exosomes from ATMs of CUG-SGA and adequate-for-gestational-age (AGA) rats. PKH-67 staining was performed to confirm the uptake of exosomes. miR-210-5p expression was measured by quantitative reverse transcription polymerase chain reaction (qRT-PCR). Glucose uptake and output were detected with glucose uptake and output assays, respectively. Insulin resistance was detected with glucose and insulin tolerance tests in vivo. The interaction between miR-210-5p and SID1 transmembrane family member 2 (SIDT2) was validated with dual-luciferase reporter assay. Results miR-210-5p was observed to be highly expressed in the exosomes derived from the ATMs of CUG-SGA rats. ATM-derived exosomes can serve as vehicles to deliver miR-210-5p into adipocytes, myocytes, and hepatocytes, where it can enhance cellular insulin resistance. SIDT2 was identified as a direct target gene of miR-210-5p. The miR-210-5p-induced insulin resistance was reversed by the restored SIDT2 expression. However, overexpression of SIDT2 abolished the inhibitory effect of CUG-SGA-ATM-exosomal miR-210-5p on insulin sensitivity in vivo. Conclusions ATM-derived exosomal miR-210-5p promoted insulin resistance in CUG-SGA rats by targeting SIDT2, which may act as a new potential therapeutic target for children born SGA with CUG.

Abstract
Objective: To analyze the clinical and genetic characteristics of pediatric patients with dual genetic diagnoses (DGD). Methods: Clinical and genetic data of pediatric patients with DGD from January 2021 to February 2022 in Peking University First Hospital were collected and analyzed retrospectively. Results: Among the 9 children, 6 were boys and 3 were girls. The age of last visit or follow-up was 5.0 (2.7,6.8) years. The main clinical manifestations included motor retardation, mental retardation, multiple malformations, and skeletal deformity. Cases 1-4 were all all boys, showed myopathic gait, poor running and jumping, and significantly increased level of serum creatine kinase. Disease-causing variations in Duchenne muscular dystrophy (DMD) gene were confirmed by genetic testing. The 4 children were diagnosed with DMD or Becker muscular dystrophy combined with a second genetic disease, including hypertrophic osteoarthropathy, spinal muscular atrophy, fragile X syndrome, and cerebral cavernous malformations type 3, respectively. Cases 5-9 were clinically and genetically diagnosed as COL9A1 gene-related multiple epiphyseal dysplasia type 6 combined with NF1 gene-related neurofibromatosis type 1, COL6A3 gene-related Bethlem myopathy with WNT1 gene-related osteogenesis imperfecta type XV, Turner syndrome (45, X0/46, XX chimera) with TH gene-related Segawa syndrome, Chromosome 22q11.2 microduplication syndrome with DYNC1H1 gene-related autosomal dominant lower extremity-predominant spinal muscular atrophy-1, and ANKRD11 gene-related KBG syndrome combined with IRF2BPL gene-related neurodevelopmental disorder with regression, abnormal movement, language loss and epilepsy. DMD was the most common, and there were 6 autosomal dominant diseases caused by de novo heterozygous pathogenic variations. Conclusions: Pediatric patients with coexistence of double genetic diagnoses show complex phenotypes. When the clinical manifestations and progression are not fully consistent with the diagnosed rare genetic disease, a second rare genetic disease should be considered, and autosomal dominant diseases caused by de novo heterozygous pathogenic variation should be paid attention to. Trio-based whole-exome sequencing combining a variety of molecular genetic tests would be helpful for precise diagnosis.

Abstract
BACKGROUND Acute lung injury (ALI) is a severe inflammatory disease with high morbidity and mortality in patients and lung transplant recipients. Tumor necrosis factor-α-induced protein 8-like 3 (TIPE3) is one of the members of the TIPE family. While TIPE2 has been demonstrated to be protective against lipopolysaccharide (LPS)-induced ALI, the role of TIPE3 in ALI is currently unidentified. METHODS To examine the role of TIPE3 in ALI, we pretreated C57BL/6 mice with control or TIPE3-lentivirus in LPS-induced ALI models. The C57BL/6 mice were randomly divided into four groups: control group; ALI-induced group; ALI-induced group with control lentivirus; and ALI-induced group with TIPE3-lentivirus. Additionally, RAW 264.7 cells were used to validate the role and molecular mechanism of TIPE3 signaling in vitro. RESULTS An increased expression of TIPE3 reduced lung histopathological damage in ALI-affected mice. ALI-affected mice treated with TIPE3-lentivirus exhibited reduced lung microvascular permeability, myeloperoxidase (MPO) activity, neutrophil buildup, and inflammation response. Additionally, over-expression of TIPE3 significantly inhibited NF-κB activation and promoted the activation of Liver X receptors alpha (LXRα). In LPS-treated RAW264.7 cells, enforced TIPE3 expression produced anti-inflammatory effects, whereas the LXR inhibitor geranylgeranyl pyrophosphate (GGPP) reversed these effects. CONCLUSIONS TIPE3 protected against LPS-induced ALI by regulating the LXRα/NF-κB signaling pathway. These results suggest that TIPE3 might provide a novel insight into the prevention of ALI.

Abstract
Fracture is one of the common diseases in the department of orthopaedics and traumatology. Jiegu Qili Tablets(Capsules) are a Chinese patent medicine commonly used to treat fractures in clinical practice, which has been included in the Class A drugs of the catalog of medicines covered by the National Medical Insurance System. However, no consensus or guideline has yet been developed to guide clinicians based on an evidence-based approach in detail, which has severely limited the clinical value of this drug. According to the guiding principle of evidence as the key, consensus as the supplement, and experience as the reference, a consensus was developed in strict accordance with the steps stipulated in the expert consensus on clinical applications of proprietary Chinese medicines. Based on literature review and questionnaire survey, the consensus was a timely summary of the existing clinical evidence on the treatment of fractures with Jiegu Qili Tablets(Capsules), and incorporated the treatment experience of a number of clinical experts. The preparation process took more than a year and the consensus(GS/CACM 293-2021) was officially released by the China Association of Chinese Medicine in September 2021, with the participation of multidisciplinary experts from 27 organizations of Chinese and Western medicine and research institutions. This article introduces the background and objectives of the consensus in detail, and describes the main process of proposal, drafting, expert consensus, and consultation. In particular, 5 consensus recommendations and 12 consensus suggestions are formed with regard to the key issues of indications, treatment timing, dose, duration, and safety in the clinical application of Jiegu Qili Tablets(Capsules) for the treatment of fractures, which guide and standardize the rational use by clinicians and improve the accuracy and safety of drugs.

Abstract
BACKGROUND Red blood cell (RBC) indices such as RBC count and RBC distribution width (RDW) are associated with heart failure and coronary artery disease, but the relationship between RBC indices and coronary artery calcification (CAC) is unclear. This study aimed to investigate RBC indices' correlation with, and predictive value for, the presence and severity of CAC. METHODS In this study, 1257 hospitalized patients who received a coronary computed tomography angiography examination were finally selected. Patients were classified into a control group (without CAC, n = 655) and a calcification group (with CAC, n = 602) according to their CAC score. The calcification group was further divided into a low calcification group, medium calcification group, and high calcification group. RESULTS In the calcification group, the RBC count was lower, and the RDW-standard deviation (SD) and RDW-coefficient of variation (CV) were higher, than those in the control group (P < .05). In the high calcification group, the RBC count was significantly lower, and the RDW-SD and RDW-CV were significantly higher, than those in the low calcification group (P < .05). Multivariate logistic regression analysis showed that RBC count, RDW-SD, and RDW-CV were independent predictors of CAC presence. Furthermore, multivariate logistic regression analysis also showed that RBC count and RDW-SD were independent predictors of severe CAC. CONCLUSIONS RBC indices were significantly associated with the presence and severity of CAC, indicating that these RBC indices have the potential to be predictors of CAC.

However, these materials undergo large volume change during cycling, resulting in severe structural degradation and capacity fading. Al2O3coating is considered an approach to improve the mechanical stability of high-capacity anode materials. To understand the effect of Al2O3coating directly, we monitored the morphology change of coated/uncoated Sn particles during cycling using operando focused ion beam-scanning electron microscopy. The results indicate that the Al2O3coating provides local protection and reduces crack formation at the early stage of volume expansion. The 3 nm Al2O3coating layer provides better protection than the 10 and 30 nm coating layer. Nevertheless, the Al2O3coating is unable to prevent the pulverization at the later stage of cycling because of large volume expansion.

Abstract
BACKGROUND Systemic lupus erythematosus (SLE) is a prototypical autoimmune disease affecting multiple organs and tissues with high cellular heterogeneity. CD8+ T cell activity is involved in the SLE pathogenesis. However, the cellular heterogeneity and the underlying mechanisms of CD8+ T cells in SLE remain to be identified. METHODS Single-cell RNA sequencing (scRNA-seq) of PBMCs from a SLE family pedigree (including 3 HCs and 2 SLE patients) was performed to identify the SLE-associated CD8+ T cell subsets. Flow cytometry analysis of a SLE cohort (including 23 HCs and 33 SLE patients), qPCR analysis of another SLE cohort (including 30 HCs and 25 SLE patients) and public scRNA-seq datasets of autoimmune diseases were employed to validate the finding. Whole-exome sequencing (WES) of this SLE family pedigree was used to investigate the genetic basis in dysregulation of CD8+ T cell subsets identified in this study. Co-culture experiments were performed to analyze the activity of CD8+ T cells. FINDINGS We elucidated the cellular heterogeneity of SLE and identified a new highly cytotoxic CD8+ T cell subset, CD161-CD8+ TEMRA cell subpopulation, which was remarkably increased in SLE patients. Meanwhile, we discovered a close correlation between mutation of DTHD1 and the abnormal accumulation of CD161-CD8+ TEMRA cells in SLE. DTHD1 interacted with MYD88 to suppress its activity in T cells and DTHD1 mutation promoted MYD88-dependent pathway and subsequently increased the proliferation and cytotoxicity of CD161-CD8+ TEMRA cells. Furthermore, the differentially expressed genes in CD161-CD8+ TEMRA cells displayed a strong out-of-sample prediction for case-control status of SLE. INTERPRETATION This study identified DTHD1-associated expansion of CD161-CD8+ TEMRA cell subpopulation is critical for SLE. Our study highlights genetic association and cellular heterogeneity of SLE pathogenesis and provides a mechanistical insight into the diagnosis and treatment of SLE.

Abstract
The study identified the blood-entering components of Sijunzi Decoction after gavage administration in rats by UPLC-Q-TOF-MS/MS, and investigated the mechanism of Sijunzi Decoction in treating Alzheimer's disease by virtue of network pharmacology, molecular docking, and experimental verification. The blood-entering components of Sijunzi Decoction were identified based on the mass spectra and data from literature and databases. The potential targets of the above-mentioned blood-entering components in the treatment of Alzheimer's disease were searched against PharmMapper, OMIM, DisGeNET, GeneCards, and TTD. Next, STRING was employed to establish a protein-protein interaction(PPI) network. DAVID was used to perform the Gene Ontology(GO) annotation and the Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway enrichment. Cytoscape 3.9.0 was used to carry out visual analysis. AutoDock Vina and PyMOL were used for molecular docking of the blood-entering components with the potential targets. Finally, the phosphatidylinositol 3-kinase(PI3K)/protein kinase B(Akt) signaling pathway enriched by the KEGG analysis was selected for validation by animal experiments. The results showed that 17 blood-entering components were detected in the serum samples after administration. Among them, poricoic acid B, liquiritigenin, atractylenolide Ⅱ, atractylenolide Ⅲ, ginsenoside Rb_1, and glycyrrhizic acid were the key components of Sijunzi Decoction in treating Alzheimer's disease. HSP90AA1, PPARA, SRC, AR, and ESR1 were the main targets for Sijunzi Decoction to treat Alzheimer's disease. Molecular docking showed that the components bound well with the targets. Therefore, we hypothesized that the mechanism of Sijunzi Decoction in treating Alzheimer's disease may be associated with the PI3K/Akt, cancer treatment, and mitogen-activated protein kinase(MAPK) signaling pathways. The results of animal experiments showed that Sijunzi Decoction significantly attenuated the neuronal damage in the hippocampal dentate gyrus area, increased the neurons, and raised the ratios of p-Akt/Akt and p-PI3K/PI3K in the hippocampus of mice. In conclusion, Sijunzi Decoction may treat Alzheimer's disease by activating the PI3K/Akt signaling pathway. The findings of this study provide a reference for further studies about the mechanism of action and clinical application of Sijunzi Decoction.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Si-Wei-Qiang-Wei Powder (SWQ) is a formulated traditional Tibetan medicine preparation that has been used clinically to treat liver and gallbladder diseases for centuries. Previous work has confirmed its clinical effectiveness, however, the specific mechanism of SWQ is still unknown. AIM OF THE STUDY This study aims to explore the anti-inflammatory effect of SWQ on cholecystitis and its possible mechanism. MATERIALS AND METHODS The main chemical components of SWQ were analyzed by HPLC. The network pharmacology database was used to screen and construct the network of the main components and molecular targets of SWQ, and to predict the molecular pathways of its core targets. Cholecystitis guinea pig model and LPS stimulated cultured human gallbladder epithelial cells (HGBEC) were used, as in vivo and in vitro methods respectively, to study the anti-cholecystitis activity of SWQ. Specifically, gallbladder wall thickness, hematoxylin-eosin (H&E) staining, and liver function indexes were used to evaluate the anti-inflammatory activities of SWQ in cholecystitis; qRT-PCR and ELISA were used to detect the changes of the production of inflammatory cytokines; Western blot analysis was used to analyze the effects of SWQ on phosphorylation of P38, ERK1/2, JNK and AKT. RESULTS SWQ decreased the indexes of ALT, AST, TBA, CHOL, DBIL in serum and TBIL, TC and Ca2+ in bile, and alleviated the wall thickness of gallbladder and hepatobiliary fibrosis in LCA-induced guinea pigs. In addition, SWQ attenuated the expression and production of TNF-α, IL-6, IL-1β, COX-2 both in liver and gallbladder. Moreover, SWQ reversed the up-regulation of p-P38, p-ERK1/2, and p-JNK in animals with cholecystitis and LPS-induced HGBEC. Furthermore, mechanistic studies indicated that SWQ inhibited the activation of ERK1/2, thereby decreasing the expression of TNF-α, IL-6, IL-1β and phosphorylation P38 and JNK. CONCLUSION In summary, our research showed that SWQ relieves gallbladder inflammation by inhibiting the MAPK pathway.

Abstract
Danggui Shaoyao San (DSS), a famous prescription, has been clinically proved to be effective in treating primary dysmenorrhea (PD). Currently there is no valid quality control data available for DSS. The main aim of the current research was to explore quality markers (Q-markers) of DSS. The chemical constituents of DSS were qualitatively identified using ultra-performance liquid chromatography tandem quadrupole time of flight mass spectrometry (UPLC-Q-TOF-MS) technology. On this basis, the targets of DSS and PD were predicted and screened using the TCMSP, SwissTargetPrediction, GeneCards, OMIM and TTD databases. Gene Ontology and Kyoto Encyclopedia of Genes and Genomes pathway analysis was performed on the core intersection targets using string and Cytoscape 3.7.1 software. Then molecular docking was conducted to screen the Q-markers of DSS in PD. A total of 126 chemical constituents, including 22 organic acids, 14 phthalides, 24 monoterpenoids, five sesquiterpene lactones, 22 triterpenoids, four phenylpropanoids and 35 other compounds were preliminarily characterized. According to network pharmacology prediction analysis, six compounds containing polyporenic acid C, senkyunolide P, alisol B 23-acetate, naringenin, gallic acid, ferulic acid and albiflorin were regarded as Q-markers of DSS. The present research established an integrative UPLC-Q-TOF-MS and network pharmacology method to discover the latent Q-markers of DSS and provided a theoretical data for the follow-up quality control of DSS.

Abstract
BACKGROUND Xiangsha Pingwei Pills (XPP) was a traditional Chinese medicine prescription, which was widely used to treat epigastric pain in China, while its systematic chemical characteristics had rarely been reported, which hindered the interpretation of the material basis of its prescription. OBJECTIVE To establish a rapid and effective component characterization method of XPP with the help of UPLC-Q-TOF-MS and the data post-processing program of Peakview 1.2 software. METHODS An ultra-high performance liquid chromatography quadrupole time-of-flight tandem mass spectrometry (UPLC-Q-TOF-MS) coupled with Peakview 1.2 software method was successfully established for the first time to investigate the complex constituents of XPP. Accurate MS and MS/MS data in positive and negative ion mode were detected. The compounds were tentatively identified based on its retention time, MS and MS/MS data, as well as reference standards and literatures. RESULTS Chemical profile of XPP was acquired, and a total of 130 compounds in XPP were preliminarily identified for the first time, including 6 organic acids, 59 flavonoids, 13 lignans, 20 terpenoids, 9 phenylpropanoids, 6 alkaloids, 5 amino acids, and 12 other compounds. CONCLUSIONS A rapid and effective UPLC-Q-TOF-MS method of the main chemical components of XPP has been established for further characterizing constituents and evaluate the overall quality control of XPP. HIGHLIGHTS This was the first report on the comprehensive analysis method of the main chemical components of XPP, which aims to lay a solid foundation for the chemical basis and overall quality control of XPP.
