Abstract
This article summarizes and organizes relevant publications in journals, along with a review of medical history, systematically summarizing the development process of dental alveolar surgery in China. The initial establishment phase (1935-1952) marked the starting point of Chinese Alveolar Surgery. Despite the impact of wars, it laid the foundation for subsequent research and practice. During the early development phase (1953-1966), the "Chinese Journal of Stomatology" was founded, which promoted the development of Alveolar Surgery. Research focused on tooth extraction methods and complications. Tooth Transplantation and Preprosthetic Surgery gradually began to take off. The stagnant phase (1967-1977) occurred due to the interruption of international exchanges, leading to an almost complete halt in the development of Alveolar Surgery. Entering the rapid catch-up phase (1978-1985), Alveolar Surgery scholars in China began striving to overcome the stagnation of the previous decade. While some progress was made, no significant innovative achievements emerged. In the scientific development phase (1986-2010), clinical research, basic experiments, and paper writing in modern Chinese Alveolar Surgery began to adhere to scientific standards with the rise of experimental medicine. The exploration and innovation stage (2011-2023) is the current development phase, during which Chinese Aveolar Surgery has reached its peak, making substantial progress in technology, clinical practices, and basic research, gradually reaching or even surpassing international advanced levels. Looking back at the development history in China, we can find the wisdom and hard work of the older generation of Alveolar Surgery scholars. However, contemporary challenges and issues, such as standardizing technology, promoting clinical practices, and talent cultivation, need to be addressed by present-day Alveolar Surgery professionals as they forge ahead.

Abstract
BACKGROUND The neural cells in the brains of patients with Parkinson's disease (PWP) display aberrant synchronized oscillatory activity within the beta frequency range. Additionally, enhanced gamma oscillations may serve as a compensatory mechanism for motor inhibition mediated by beta activity and also reinstate plasticity in the primary motor cortex affected by Parkinson's disease. Transcranial alternating current stimulation (tACS) can synchronize endogenous oscillations with exogenous rhythms, thereby modulating cortical activity. The objective of this study is to investigate whether the addition of tACS to multidisciplinary intensive rehabilitation treatment (MIRT) can improve symptoms of PWP so as to enhance the quality of life in individuals with Parkinson's disease based on the central-peripheral-central theory. METHODS The present study was a randomized, double-blind trial that enrolled 60 individuals with Parkinson's disease aged between 45 and 70 years, who had Hoehn-Yahr scale scores ranging from 1 to 3. Participants were randomly assigned in a 1:1 ratio to either the tACS + MIRT group or the sham-tACS + MIRT group. The trial consisted of a two-week double-blind treatment period followed by a 24-week follow-up period, resulting in a total duration of twenty-six weeks. The primary outcome measured the change in PDQ-39 scores from baseline (T0) to 4 weeks (T2), 12 weeks (T3), and 24 weeks (T4) after completion of the intervention. The secondary outcome assessed changes in MDS-UPDRS III scores at T0, the end of intervention (T1), T2, T3, and T4. Additional clinical assessments and mechanistic studies were conducted as tertiary outcomes. DISCUSSION The objective of this study is to demonstrate that tACS can enhance overall functionality and improve quality of life in PWP, based on the framework of MIRT. Additionally, it seeks to establish a potential correlation between these therapeutic effects and neuroplasticity alterations in relevant brain regions. The efficacy of tACS will be assessed during the follow-up period in order to optimize neuroplasticity and enhance its potential impact on rehabilitation efficiency for PWP.

Abstract
Purpose A better understanding of the factors that influence engagement is needed to provide a reference for conducting genetic testing in female relatives of patients with hemophilia (PWH). We therefore determined the perceptions and understanding of genetic testing among female relatives of PWH in China. Methods We carried out a qualitative study using in-depth, semi-structured interviews with 11 female relatives of PWH in Shanxi Province, China. The resulting data were analyzed using thematic analyses. Results This study extracted four topics: uncertainty about carrier genetic status; limited understanding of genetic testing; coexistence of positive and negative coping; and multi-aspect demands. Conclusion Healthcare professionals should provide personalized and multidimensional health education and comprehensive decision-making support to female relatives of PWH, to enhance their motivation and willingness to undergo genetic testing. It is also important to actively improve relevant policies, strengthen the genetic testing service system, and promote the popularization of genetic testing in female relatives of PWH.

Abstract
BACKGROUND Differential diagnosis of wide QRS tachycardia (WQCT) has been a challenging issue. Published algorithms to distinguish ventricular tachycardia (VT) and supraventricular tachycardia (SVT) have limited diagnostic capabilities. METHODS A total of 278 patients with WQCT from January 2010 to March 2022 were enrolled. The electrophysiological study confirmed SVT in 154 patients and VT in 65 ones. Two hundred nineteen WQCT 12-lead ECGs were randomly divided into development cohort (n = 165) and testing cohort (n = 54) data sets. The development cohort was split into a training group (n = 115) and an internal validation group (n = 50). Forty ECG features extracted from the 219 WQCT ECGs are fed into 9 iteratively trained ML algorithms. This novel ML algorithm was also compared with four published algorithms. RESULTS In the development cohort, the Gradient Boosting Machine (GBM) model displayed the maximum area under curve (AUC) (0.91, 95% confidence interval (CI) 0.81-1.00). In the testing cohort, the GBM model had a higher AUC of 0.97 compared to 4 validated ECG algorithms, namely, Brugada (0.68), avR (0.62), RWPTII (0.72), and LLA algorithms (0.70). Accuracy, sensitivity, specificity, negative predictive value, and positive predictive value of the GBM model were 0.94, 0.97, 0.90, 0.94, and 0.95, respectively. CONCLUSIONS A GBM ML model contributes to distinguishing SVT from VT based on surface ECG features. In addition, we were able to identify important indicators for distinguishing WQCT.

Abstract
We aimed to explore the effects of single nucleotide polymorphisms (SNPs) in tropoelastin gene on tropoelastin mRNA and elastin expressions in human aortic smooth muscle cells (HASMCs). Two SNP loci, rs2071307 (G/A) and rs1785598 (G/C), were selected to construct recombinant lentivirus vectors carrying wild-type and mutant tropoelastin gene. Recombinant plasmids including pWSLV-02-ELN, pWSLV-02-ELN-mut1, and pWSLV-02-ELN-mut2 were constructed, before being amplified by polymerase chain reaction (PCR) and sequenced. The prepared plasmids and the packaging plasmids (pVSV-G and psPAX2) were cotransfected into HEK293T cells to obtain recombinant lentiviruses carrying tropoelastin gene. Afterward, HASMCs were infected with recombinant lentiviruses, and the positive cells sorted by flow cytometry were amplified. Four stable HASMCs cell lines including pWSLV-02-ELN, pWSLV-02-ELN-mut1, pWSLV-02-ELN-mut2, and pWSLV-02 vector were constructed. The expressions of tropoelastin mRNA and elastin in HASMCs were detected by real-time quantitative reverse transcription-PCR and western blot, respectively. Recombinant plasmids including pWSLV-02-ELN-mut1, pWSLV-02-ELN-mut2, and pWSLV-02-ELN were successfully constructed. Recombinant lentiviruses carrying tropoelastin gene were obtained via lentivirus packaging. After infection for 24 h, 3 days and 5 days in HASMCs, tropoelastin mRNA expressions in pWSLV-02-ELN-mut1 and pWSLV-02-ELN-mut2 groups were significantly lower than that of pWSLV-02-ELN group. Besides, after infection for 24 h, 3 days, and 5 days, elastin levels in pWSLV-02-ELN-mut1 and pWSLV-02-ELN-mut2 groups were significantly lower than that in pWSLV-02-ELN group. In conclusion, SNPs mutation of tropoelastin gene affected the expression of tropoelastin mRNA and elastin, suggesting that the polymorphisms of rs2071307 and rs17855988 in tropoelastin gene might be important factors for AD development.

Abstract
ABSTRACT Patients with chronic pain often experience exaggerated pain response and aversive emotion, such as anxiety and depression. Central plasticity in the anterior cingulate cortex (ACC) is assumed to be a critical interface for pain perception and emotion, which has been reported to involve activation of NMDA receptors. Numerous studies have documented the key significance of cGMP-dependent protein kinase I (PKG-I) as a crucial downstream target for the NMDA receptor-NO-cGMP signaling cascade in regulating neuronal plasticity and pain hypersensitivity in specific regions of pain pathway, ie, dorsal root ganglion or spinal dorsal horn. Despite this, whether and how PKG-I in the ACC contributes to cingulate plasticity and comorbidity of chronic pain and aversive emotion has remained elusive. Here, we uncovered a crucial role of cingulate PKG-I in chronic pain and comorbid anxiety and depression. Chronic pain caused by tissue inflammation or nerve injury led to upregulation of PKG-I expression at both mRNA and protein levels in the ACC. Knockdown of ACC-PKG-I relieved pain hypersensitivity as well as pain-associated anxiety and depression. Further mechanistic analysis revealed that PKG-I might act to phosphorylate TRPC3 and TRPC6, leading to enhancement of calcium influx and neuronal hyperexcitability as well as synaptic potentiation, which results in the exaggerated pain response and comorbid anxiety and depression. We believe this study sheds new light on the functional capability of ACC-PKG-I in modulating chronic pain as well as pain-associated anxiety and depression. Hence, cingulate PKG-I may represent a new therapeutic target against chronic pain and pain-related anxiety and depression.

Abstract
Objective: To explore the role of digital three-dimensional printing technology and multifunctional board in the treatment of mandibular fracture in children. Methods: From January 2006 to January 2022, 42 children with mandibular fracture were treated by Department of Stomatology, in The First Affiliated Hospital of Bengbu Medical College, including 25 males and 17 females. The patients, aged from 4 to 12 years, with the median age was 10 years old, were divided into observation group (22 cases) and routine group (20 cases) according to the treatment methods. In the observation group, the multifunctional board was made before operation, and the CT data of the children were imported into Mimics software in".dicom"format, and the displaced mandible was virtually reset. The jaw reduction model was made by three-dimensional printing, and the surgical operation was simulated on the reduction model to determine the model and position of the internal fixation device and shape it. During the operation, the fracture was reduced and fixed according to the preoperative design; The conventional group was treated with open reduction and internal fixation of mandibular fracture by traditional methods, and the clinical application value was compared and analyzed through the intraoperative situation, occlusal relationship, and follow-up of the two groups. Results: The total intraoperative bleeding volume [(30.25±4.02) ml] and surgical time [(64.3±9.2) min] in the observation group were significantly lower than those in the conventional group [(35.13±5.69) ml and (84.6±13.9) min, respectively] (F=6.18, P=0.003; F=1.32, P=0.001). The excellent and good rate of occlusal relationship in the observation group [96% (21/22)] was significantly higher than that in the conventional group [85% (17/20)] (F=4.27, P=0.039). The incidence of complications, the observation group, 1 case of poor occlusion, 1 case of postoperative infection; In the routine group, there were 3 cases with poor occlusion, 1 case with nerve injury, 1 case with root injury and 1 case with tooth germ injury. Conclusions: The application of digitization three-dimensional printing technology combined with multifunctional occlusal plate in children's mandibular fracture is minimally invasive, safe, efficient and accurate, and the clinical effect is good.

Abstract
Histone modification plays an important role in pathological cardiac hypertrophy and heart failure. In this study we investigated the role of a histone arginine demethylase, Jumonji C domain-containing protein 6 (JMJD6) in pathological cardiac hypertrophy. Cardiac hypertrophy was induced in rats by subcutaneous injection of isoproterenol (ISO, 1.2 mg·kg-1·d-1) for a week. At the end of the experiment, the rats underwent echocardiography, followed by euthanasia and heart collection. We found that JMJD6 levels were compensatorily increased in ISO-induced hypertrophic cardiac tissues, but reduced in patients with heart failure with reduced ejection fraction (HFrEF). Furthermore, we demonstrated that JMJD6 overexpression significantly attenuated ISO-induced hypertrophy in neonatal rat cardiomyocytes (NRCMs) evidenced by the decreased cardiomyocyte surface area and hypertrophic genes expression. Cardiac-specific JMJD6 overexpression in rats protected the hearts against ISO-induced cardiac hypertrophy and fibrosis, and rescued cardiac function. Conversely, depletion of JMJD6 by single-guide RNA (sgRNA) exacerbated ISO-induced hypertrophic responses in NRCMs. We revealed that JMJD6 interacted with NF-κB p65 in cytoplasm and reduced nuclear levels of p65 under hypertrophic stimulation in vivo and in vitro. Mechanistically, JMJD6 bound to p65 and demethylated p65 at the R149 residue to inhibit the nuclear translocation of p65, thus inactivating NF-κB signaling and protecting against pathological cardiac hypertrophy. In addition, we found that JMJD6 demethylated histone H3R8, which might be a new histone substrate of JMJD6. These results suggest that JMJD6 may be a potential target for therapeutic interventions in cardiac hypertrophy and heart failure.

Abstract
The nuclear incompressibility is a key parameter of the nuclear equation of state that can be extracted from the measurements of the so-called "breathing mode" of finite nuclei. The most serious discrepancy so far is between values extracted from Pb and Sn, that has provoked the longstanding question "Why is tin so soft?". To solve this puzzle, a fully self-consistent quasiparticle random-phase approximation plus quasiparticle-vibration coupling approach based on Skyrme-Hartree-Fock-Bogoliubov is developed. We show that the many-body correlations introduced by quasiparticle-vibration coupling, which shift the isoscalar giant monopole resonance energy in Sn isotopes by about 0.4 MeV more than the energy in ^{208}Pb, play a crucial role in providing a unified description of the isoscalar giant monopole resonance in Sn and Pb isotopes. The best description of the experimental strength functions is given by SV-K226 and KDE0, which are characterized by incompressibility values K_{∞}=226 MeV and 229 MeV, respectively, at mean field level.

Abstract
Full-endoscopic spinal surgery via transforaminal approach (TF-FESS) originated from the minimally invasive techniques of percutaneous interventional treatment of intervertebral disc diseases through posterolateral approach.Thanks to the continuous development and improvement of full-endoscopic equipment alongside surgical instruments and techniques, a developed technical system has been established in discectomy, spinal canal decompression, interbody fusion, etc. The combination of these basic techniques can treat relatively complex degenerative spinal diseases. The core techniques of TF-FESS include percutaneous puncture, foraminoplasty, spinal canal decompression, discectomy, annulus fibrosus suture, interbody fusion. This paper elaborates on the key points of the core techniques, indications, advantages, disadvantages, and prospects of the TF-FESS.

Abstract
We wished to establish an expert consensus on late stage of critical care (CC) management. The panel comprised 13 experts in CC medicine. Each statement was assessed based on the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) principle. Then, the Delphi method was adopted by 17 experts to reassess the following 28 statements. (1) ESCAPE has evolved from a strategy of delirium management to a strategy of late stage of CC management. (2) The new version of ESCAPE is a strategy for optimizing treatment and comprehensive care of critically ill patients (CIPs) after the rescue period, including early mobilization, early rehabilitation, nutritional support, sleep management, mental assessment, cognitive-function training, emotional support, and optimizing sedation and analgesia. (3) Disease assessment to determine the starting point of early mobilization, early rehabilitation, and early enteral nutrition. (4) Early mobilization has synergistic effects upon the recovery of organ function. (5) Early functional exercise and rehabilitation are important means to promote CIP recovery, and gives them a sense of future prospects. (6) Timely start of enteral nutrition is conducive to early mobilization and early rehabilitation. (7) The spontaneous breathing test should be started as soon as possible, and a weaning plan should be selected step-by-step. (8) The waking process of CIPs should be realized in a planned and purposeful way. (9) Establishment of a sleep-wake rhythm is the key to sleep management in post-CC management. (10) The spontaneous awakening trial, spontaneous breathing trial, and sleep management should be carried out together. (11) The depth of sedation should be adjusted dynamically in the late stage of CC period. (12) Standardized sedation assessment is the premise of rational sedation. (13) Appropriate sedative drugs should be selected according to the objectives of sedation and drug characteristics. (14) A goal-directed minimization strategy for sedation should be implemented. (15) The principle of analgesia must be mastered first. (16) Subjective assessment is preferred for analgesia assessment. (17) Opioid-based analgesic strategies should be selected step-by-step according to the characteristics of different drugs. (18) There must be rational use of non-opioid analgesics and non-drug-based analgesic measures. (19) Pay attention to evaluation of the psychological status of CIPs. (20) Cognitive function in CIPs cannot be ignored. (21) Delirium management should be based on non-drug-based measures and rational use of drugs. (22) Reset treatment can be considered for severe delirium. (23) Psychological assessment should be conducted as early as possible to screen-out high-risk groups with post-traumatic stress disorder. (24) Emotional support, flexible visiting, and environment management are important components of humanistic management in the intensive care unit (ICU). (25) Emotional support from medical teams and families should be promoted through"ICU diaries"and other forms. (26) Environmental management should be carried out by enriching environmental content, limiting environmental interference, and optimizing the environmental atmosphere. (27) Reasonable promotion of flexible visitation should be done on the basis of prevention of nosocomial infection. (28) ESCAPE is an excellent project for late stage of CC management.

Abstract
Objective: To produce chimeric antigen receptor T cells (CAR-T) targeting human hepatocyte growth factor/c-Met (HGF/c-Met) protein and detect its cytotoxicity against non-small cell lung cancer (NSCLC) cells H1975 in vitro. Methods: The whole gene sequence of c-Met CAR containing c-Met single-chain fragment variable was synthesized and linked to lentiviral vector plasmid, plasmid electrophoresis was used to detect the correctness of target gene. HEK293 cells were transfected with plasmid and the concentrated solution of the virus particles was collected. c-Met CAR lentivirus was transfected into T cells to obtain second-generation c-Met CAR-T and the expression of CAR sequences was verified by reverse transcription-quantitative real-time polymerase chain reaction (RT-qPCR) and western blot, and the positive rate and cell subtypes of c-Met CAR-T cells were detected by flow cytometry. The positive expression of c-Met protein in NSCLC cell line H1975 was verified by flow cytometry, and the negative expression of c-Met protein in ovarian cancer cell line A2780 was selected as the control. The cytotoxicity of c-Met CAR-T to H1975 was detected by lactate dehydrogenase (LDH) cytotoxicity assay at 1∶1, 5∶1, 10∶1 and 20∶1 of effector: target cell ratio (E∶T). Enzyme-linked immunosorbent assay (ELISA) was used to detect the release of cytokines such as TNF-α, IL-2 and IFN-γ from c-Met CAR-T co-cultured with H1975. Results: The size of band was consistent with that of designed c-Met CAR, suggesting that the c-Met CAR plasmid was successfully constructed. The results of gene sequencing were consistent with the original design sequence and lentivirus was successfully constructed. CAR molecules expression in T cells infected with lentivirus was detected by western blot and RT-qPCR, which showed c-Met CAR-T were successfully constructed. Flow cytometry results showed that the infection efficiency of c-Met CAR in T cells was over 38.4%, and the proportion of CD8(+) T cells was increased after lentivirus infection. The NSCLC cell line H1975 highly expressed c-Met while ovarian cancer cell line A2780 negatively expressed c-Met. LDH cytotoxicity assay indicated that the killing efficiency was positively correlated with the E∶T, and higher than that of control group, and the killing rate reached 51.12% when the E∶T was 20∶1. ELISA results showed that c-Met CAR-T cells released more IL-2, TNF-α and IFN-γ in target cell stimulation, but there was no statistical difference between c-Met CAR-T and T cells in the non-target group. Conclusions: Human NSCLC cell H1975 expresses high level of c-Met which can be used as a target for immunotherapy. CAR-T cells targeting c-Met have been successfully produced and have high killing effect on c-Met positive NSCLC cells in vitro.

Abstract
The O-carbamoyltransferase VtdB catalyzes the carbamoylation of venturicidin B, which is essential for the biosynthesis of the antibiotic venturicidin A. Here, the crystal structures of VtdB and VtdB in complex with the intermediate carbamoyladenylate (VtdBCAO) were determined at resolutions of 2.99 Å and 2.90 Å, respectively. The structures resemble the conserved YrdC-like and specific Kae1-like domains. A magnesium ion and the intermediate carbamoyladenylate were also observed in the Kae1-like domain of VtdB. The structure of VtdBCAO in complex with the substrate venturicidin B was modeled by a molecular docking method to better understand the substrate binding mode, revealing a novel venturicidin B binding pocket.

Abstract
PURPOSE To probe into the needs and barriers underlying patients' participation in shared decision-making related to rehabilitation nursing for hemophilic arthropathy. PATIENTS AND METHODS The phenomenological research approach was adopted to conduct a series of semi-structured, in-depth interviews with 15 patients with hemophilic arthropathy undergoing rehabilitative treatments, 10 caregivers, and 7 healthcare providers from a hemophilia treatment center in Shanxi province, China. Colaizzi's seven-step method of data analysis was applied to organize, analyze, and extract the themes from the interview materials. RESULTS Three main themes emerged from the analysis: the status quo of the healthcare system (insufficient decision support systems and mismatch between healthcare providers' and patients' resources), circumstances of provider-patient interactions (lack of information exchange and unbalanced power structure between healthcare providers and patients), and patient-related factors influencing participation in decision-making (lack of self-efficacy, personal characteristics, family and social decision support, and attitude toward participation in decision-making). CONCLUSION Participation in rehabilitation decision-making among patients with hemophilic arthropathy is affected by multiple barriers. Healthcare professionals should improve their understanding of shared decision-making, offer patients active guidance on participating in the decision-making process, prioritize their affective needs, and formulate professional and effective solutions to support shared decision-making as early as possible.

Abstract
Atherosclerosis is the most common arterial disease and is closely related to vascular calcification. CircHIPK3 has been implicated in atherosclerosis development, but the possible downstream regulatory mechanisms remain unclear. The levels of circHIPK3, miR-106a and MFN2 in tissues and blood samples of patients with atherosclerosis were detected by RT-qPCR. The levels of circHIPK3, miR-106a and MFN2 were detected by RT-qPCR and the expression levels of MFN2, osteogenic and cartilage differentiation marker proteins were detected by western blot in vitro. ALP staining, Alizarin Red staining, and calcium content detection evaluated the degree of osteogenic differentiation of cells. Alcian blue staining detected the level of cell cartilage differentiation. Luciferase detected the targeting relationship between circHIPK3 and miR-106a-5p, as well as miR-106a-5p and MFN2. CircHIPK3 and MFN2 were low expressed and miR-106a-5p was highly expressed in tissues and blood samples of patients with atherosclerosis, as well as vascular smooth muscle cell (VSMC) with osteogenic and cartilage differentiation. Overexpression of circHIPK3 reduced the cell mineralization and calcium content. Overexpression of circHIPK3 inhibited osteogenic differentiation by decreasing ALP activity, RUNX2, and OPG expression, and increasing SM22α and SMA level. What's more, overexpression of circHIPK3 decreased the chondrogenic differentiation by inhibiting the protein level of SOX9, aggrecan, and collagen II. CircHIPK3 targeted miR-106a-5p and miR-106a-5p targeted MFN2. MiR-106a-5p overexpression or MFN2 depletion repressed the effect of circHIPK3 overexpression on VSMC calcification. CircHIPK3 regulated osteogenic and cartilage differentiation of VSMC via miR-106a-5p/MFN2 axis, indicating a target for treating vascular calcification.

Abstract
A new hybridization of berberine and benzimidazoles was performed to produce 13-(benzimidazolylmethyl)berberines (BMB) as potentially broad-spectrum antibacterial agents with the hope of confronting multidrug-resistant bacterial infections in the livestock industry. Some of the newly prepared hybrids showed obvious antibacterial effects against tested strains. Particularly, 13-((1-octyl-benzimidazolyl)methyl)berberine 6f (OBMB-6f) was found to be the most promising compound that not only exerted a strong activity (MIC = 0.25-2 μg/mL) and low cytotoxicity but also possessed a fast bactericidal capacity and low propensity to develop resistance toward Staphylococcus aureus and Escherichia coli even after 26 serial passages. Moreover, OBMB-6f displayed the ability to prevent bacterial biofilm formation at low and high temperatures. The mechanistic exploration revealed that OBMB-6f could significantly disintegrate bacterial membranes, markedly facilitate intracellular ROS generation, and efficiently intercalate into DNA. These results provided a profound insight into BMB against multidrug-resistant bacterial infections in the livestock industry.

Abstract
Ambient fine particulate matters (PM2.5) refer to particulate matters with an aerodynamic diameter less than or equal to 2.5 μm. PM2.5 enter the body through the target organ-lung, and can induce a variety of adverse health effects (such as cardiovascular diseases, diabetes, respiratory diseases, neurodegenerative diseases and adverse birth outcomes). PM2.5 are known to have complex compositions (including water-soluble/-insoluble components and biological components), diverse sources and capacity of secondary transformation. Numerous epidemiological and toxicological studies indicated that different components of PM2.5 may induce adverse health effects through different biological mechanisms. In adddition, co-exposure of different components and their interaction should also be considered. Thus here we have systematically reviewed studies in recent years about the toxicological effects and underlying mechanisms of different components of ambient fine particulate matters, including inflammatory response, oxidative stress, endoplasmic reticulum stress, activation of the NF-κB signaling pathway and so on. The information may give some insights into the prevention and treatment of adverse health effects caused by exposure to different components of PM2.5.

Abstract
OBJECTIVE To evaluate the efficacy and safety of 585 nm Q-switched laser in the treatment of acne inflammatory lesions and postinflammatory erythema. METHODS A total of 25 patients with moderate facial acne, symmetrical distribution of inflammatory lesions and postinflammatory erythema on both sides of the face, were enrolled. Among the 25 patients, 22 patients completed all the treatment and evaluation, and 3 patients were lost to follow-up. 585 nm Q-switched laser was used on a randomly selected side of the face for three times of treatment at a 2 week interval. The evaluations were made before each treatment, 2 and 4 weeks after the last treatment, therefore the evaluation time points were before the treatment, weeks 2, 4, 6, and 8, respectively, for a total of 5 times. Acne severity was assessed using the investigator' s global assessment (IGA) score, and erythema severity was assessed using the investigator' s subjective erythema score and narrow-spectrum reflectance spectrophotometer at each follow-up. RESULTS After 3 times of treatment, there was statistically significant difference between the IGA score in week 8 and before treatment on both sides(Z=2.64, P < 0.01; Z=2.67, P < 0.01). There was no significant difference in IGA score between the treatment side and the control side before treatment and in week 8 (P=0.59, P=0.26). There was statistically significant difference between the investiga-tor' s subjective erythema score in week 8 and before treatment on the treatment side(Z=4.24, P < 0.01), while no significant difference was showed on the control side(Z=1.73, P=0.08). In week 8, the investigator's subjective erythema score of the treatment side was lower than that of the control side (Z=3.61, P < 0.01). The erythema index of the treatment side was significantly decreased at 5 time points (P < 0.01), and the index decreased significantly in week 8 compared with the index before treatment (P < 0.01), while the erythema index of the control side was not significantly different at 5 time points. The treatment related adverse events included erythema and edema after treatment and pain during treatment, the severity was mild to moderate, which resolved spontaneously within 1 to 3 days. Nine patients were very satisfied with the treatment, 7 patients were satisfied, and 6 patients considered average. CONCLUSION 585 nm Q-switched laser has some effect in the treatment of postinflammatory erythema, and it ensures good tolerance and safety. There was no statistically significant difference between the treatment side and the control side on the improvement of acne inflammatory lesions.

Abstract
SARS‐CoV‐2 wreaks havoc around the world, triggering the COVID‐19 pandemic. It has been confirmed that the endoribonuclease NSP15 is crucial to the viral replication, and thus identified as a potential drug target against COVID‐19. The NSP15 protein was used as the target to conduct high‐throughput virtual screening on 30,926 natural products from the NPASS database to identify potential NSP15 inhibitors. And 100 ns molecular dynamics simulations were performed on the NSP15 and NSP15‐NPC198199 system. In all, 10 natural products with high docking scores with NSP15 protein were obtained, among which compound NPC198199 scored the highest. The analysis of the binding mode between NPC198199 and NSP15 found that NPC198199 would form H‐bond interactions with multiple key residues at the catalytic site. Subsequently, a series of post‐dynamics simulation analyses (including RMSD, RMSF, PCA, DCCM, RIN, binding free energy, and H‐bond occupancy) were performed to further explore inhibitory mechanism of compound NPC198199 on NSP15 protein at the molecular level. The research strongly indicates that the 10 natural compounds screened can be used as potential inhibitors of NSP15, and provides valuable information for the subsequent drug discovery of anti‐SARS‐CoV‐2.

Abstract
The formation of fat-laden foam cells plays an important role in the initiation and progression of atherosclerosis (AS). Amentoflavone (AF) is found in various traditional Chinese medicines, such as ginkgo biloba, which are used to treat cardiovascular diseases (CVDs). We aimed to explore the potential effects and mechanisms of AF on lipid accumulation, and its possible application in atherosclerotic cardiovascular disease (ASCVD). Cellular models of lipid accumulation were established by treatment of HUASMCs and THP-1 cells with oxidized low-density lipoprotein (ox-LDL). Cell viability, lipid accumulation, and ox-LDL uptake were assessed. Small interfering RNAs (siRNAs) and overexpression plasmids were used to reveal the hierarchical correlations of regulatory pathways. AF reduced the lipid accumulation and ox-LDL uptake induced by ox-LDL, and reduced the expression levels of cluster of differentiation 36 (CD36) and peroxisome proliferator-activated receptor gamma (PPARγ) proteins, while the expression level of ATP binding cassette subfamily A member 1 (ABCA1) increased. Knockdown of PPARγ or CD36 with siRNAs prevented ox-LDL-induced lipid accumulation. Overexpression of CD36 or PPARγ promoted the lipid accumulation induced by ox-LDL and eliminated the effect of AF on ox-LDL-induced lipid accumulation. Overall, AF prevents ox-LDL-induced lipid accumulation by suppressing the PPARγ/CD36 signaling pathway.

Abstract
The pathogenesis of atherosclerosis is closely related to endothelial cell injury caused by lipid peroxidation-induced ferroptosis. Tanshinone IIA (TSA) protects endothelial tissues from damage. In this study, we investigated whether TSA exerts its protective effect on endothelial cells by inhibiting ferroptosis. Ferroptosis was induced in human coronary artery endothelial cells (HCAECs), and cells were treated with TSA. Morphological examination indicated that TSA exerted a significant protective effect on the HCAECs. This was further confirmed by LDH release and cell death detection assays. Flow cytometry revealed that TSA significantly reduced the excessive accumulation of total cellular ROS and lipid ROS caused by ferroptosis inducers. TSA also restored the reduction of glutathione (GSH), a potent and abundant reductant in cells. In addition, we found that TSA promoted the expression of NRF2, an essential player in response to oxidative stress, and its downstream genes. Immunofluorescent staining revealed that TSA promoted the nuclear translocation of NRF2. Increased nuclear translocation of NRF2 was validated by Western blot evaluation of cytoplasmic and nuclear protein extracts. Furthermore, NRF2 inhibition abolished the protective effects of TSA on HCAECs. These data demonstrate that TSA represses ferroptosis via activation of NRF2 in HCAECs.

Abstract
OBJECTIVES This study investigated institutional and personal barriers to and facilitators of neonatal palliative care facing neonatal professionals in China. METHODS A cross-sectional questionnaire surveyed 231 neonatal clinicians employed in 5 neonatal intensive care units from 2 children's hospitals and 3 medical centers in China. MEASUREMENTS The translated modified version of the Neonatal Palliative Care Attitude Scale was used to survey neonatal clinicians' attitudes and beliefs regarding neonatal palliative care. RESULTS Findings highlight 4 facilitators and 5 barriers among participating clinicians. Participants gave contradictory responses regarding the relative importance of curative treatment versus palliative care in the NICU. Negatively traumatic feelings, cultural issues and moral distress may impact this contradictory response and discourage clinicians from providing neonatal palliative care. Additionally, neonatologists and nurses held differing attitudes on several topics (p < 0.05). CONCLUSION Further research should address strategies to improve knowledge and attitudes and relieve moral distress in NICU clinicians. Neonatal clinicians providing neonatal palliative care should receive regular palliative care training addressing culture-specific issues and communication skills. PRACTICE IMPLICATIONS Study findings will be beneficial to inform clinical education and practice. Regular interdisciplinary team training is needed to enhance support for palliative care and decrease clinicians' moral distress during end-of-life care.

Abstract
Sodium-glucose cotransporter 2 inhibitor (SGLT2i) has been reported to improve glycemic control. This study was designed to investigate the effects of SGLT2i dapagliflozin (dapa) on cardiomyopathy induced by isoproterenol (ISO) and its potential mechanisms. Fifty male Sprague Dawley rats were randomly assigned to the control (n=10) and the ISO (2.5 mg/kg/day)-treated groups (n=40). After 2 weeks, the 28 surviving rats with obvious left ventricular dysfunction in the ISO group were randomized into three medication groups, including the angiotensin receptor neprilysin inhibitor (ARNI) sacubitril/valsartan group (S/V, n=9), the dapa group (n=9), and the ISO group (n=10) for 4 weeks. Next, electrical programmed stimulation was performed in all the groups to evaluate their susceptibility to ventricular arrhythmias (VAs). Compared to the ISO rats, the dapa administration not only effectively reduced the cumulative risk of death, the myocardial fibrosis, the plasma angiotensin II levels and its functional receptor AT1R protein expressions in the heart, and the proinflammatory cytokine levels in the cardiac tissue of the ISO-treated rats, but it also improved their cardiac function and inhibited oxidative stress. These effects were similar to S/V. However, dapa showed a greater efficacy than S/V in reducing the left ventricular end-diastolic volumes, lowing the heart rates and VAs, and decreasing the body weights and plasma glucose levels. The mechanisms by which dapa exerts protective effects on cardiomyopathy may be related to its indirect antioxidant capacity and direct hypoglycemic action.

Abstract
Patients with neuropathic pain often experience comorbid psychiatric disorders. Cellular plasticity in the anterior cingulate cortex (ACC) is assumed to be a critical interface for pain perception and emotion. However, substantial efforts have thus far been focused on the intracellular mechanisms of plasticity rather than the extracellular alterations that might trigger and facilitate intracellular changes. Laminin, a key element of the extracellular matrix (ECM), consists of one α-, one β-, and one γ-chain and is implicated in several pathophysiological processes. Here, we showed in mice that laminin β1 (LAMB1) in the ACC was significantly downregulated upon peripheral neuropathy. Knockdown of LAMB1 in the ACC exacerbated pain sensitivity and induced anxiety and depression. Mechanistic analysis revealed that loss of LAMB1 caused actin dysregulation via interaction with integrin β1 and the subsequent Src-dependent RhoA/LIMK/cofilin pathway, leading to increased presynaptic transmitter release probability and abnormal postsynaptic spine remodeling, which in turn orchestrated the structural and functional plasticity of pyramidal neurons and eventually resulted in pain hypersensitivity and anxiodepression. This study sheds new light on the functional capability of ECM LAMB1 in modulating pain plasticity and identifies a mechanism that conveys extracellular alterations to intracellular plasticity. Moreover, we identified cingulate LAMB1/integrin β1 signaling as a promising therapeutic target for the treatment of neuropathic pain and associated anxiodepression.

Abstract
Objectives: In this research our aim was to investigate Chinese parents' awareness of pediatric COVID-19 in relation to protecting their children. Methods: A cross-sectional study was conducted in Fujian provinces in China using a Web-based questionnaire to survey parents of children aged 6 to 16 years old. Results: The sample included 1222 participants. Overall, 99.2% of participants were aware of respiratory transmission of COVID-19, and 75.6% also believed fecal-oral transmission to be possible. Although 98.3% of participants claimed to know how to wear and remove masks properly, some parents were unaware of good handwashing techniques and answered incorrectly regarding cough etiquette. Parents also seemed uncertain about pediatric COVID-19 symptoms. Awareness scores significantly differed across parental role, educational attainment levels, and social-economic levels (p value < .005), with fathers, more educated parents, and those of higher income showing greater levels of awareness.Conclusion: Research results suggest an urgent need for parental education regarding COVID-19 in children, especially regarding handwashing techniques and cough etiquette; educational outreach for both parents and schoolchildren is critical.

Abstract
BACKGROUND COVID-19 is caused by the Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2), which was discovered in 2019 and spread around the world in a short time. SARS-CoV-2 nucleic acid amplification tests (NAATs) have been rapidly developed and quickly applied to clinical testing of COVID-19. Aim of this study was to evaluate the performance of four NAAT assays. METHODS Limit of detection (LOD), precision, accuracy, analytical specificity and analytical interference studies on four NAATs (Daan, Sansure, Hybribio, and Bioperfectus) were performed according to Clinical Laboratory Standards Institute protocols and guidelines. The four NAATs were compared using 46 clinical samples. RESULTS The LOD of the N gene for Daan, Sansure, and Hybribio was 500 copies/mL, and that for Bioperfectus was 1,000 copies/mL. The LOD of the ORF1ab gene for Daan, Bioperfectus, and Hybribio was 3,000 copies/mL, and that for Sansure was 2,000 copies/mL. A good precision was shown at the concentration above 20% of the LOD for all four NAATs, with all individual coefficients of variation below 3.6%. Satisfactory results were also observed in the accuracy, analytical specificity, and analytical interference tests. The results of the comparison test showed that Daan, Sansure, and Hybribio NAATs could detect the samples with a specificity of 100% (30/30) and a sensitivity of 100% (16/16), whereas Bioperfectus NAAT detected the samples with a specificity of 100% (30/30) and a sensitivity of 81.25% (13/16). However, no significant difference in sensitivity was found between Bioperfectus NAAT and the three other NAATs (p > 0.05). CONCLUSIONS The four SARS-CoV-2 NAATs showed comparable performance, with the LOD of the N gene lower than the LOD of the ORF1ab gene.

Abstract
The purpose of this study was to improve the ability to visualize and diagnose congenital nephrogenic diabetes insipidus (CNDI). The clinical manifestations, laboratory examination findings, imaging features and treatment outcomes of 22 patients with CNDI admitted to the First Affiliated Hospital of Zhengzhou University from May 2013 to May 2020 were retrospectively analyzed. Among the 22 patients with CNDI, 86.4% (19 cases) were male. The age of the 22 patients ranged from 2 months to 47 years old, in which 20 cases were younger than 30 years old and 2 cases were older than 30 years old. The clinical manifestations were polydipsia and polyuria, accompanied with various degrees of fever, defects in growth and development, and increased serum creatinine in some patients. Fifteen patients (68.2%) had different degrees of bilateral kidney and ureteral hydronephrosis, and increased residual urine volume in the bladder. Pituitary magnetic resonance imaging (MRI) enhanced scan showed that the high signal intensity in the posterior pituitary lobe was not detectable in 5 cases (22.7%), and blurred in 6 cases (27.3%). Seven tested patients were all found AVPR2 gene mutation. For patients with suspected CNDI, water-inhibiting vasopressin test and genetic testing should be performed in time so as to confirm diagnosis and treat as early as possible.

Abstract
Cardiovascular disease is the main cause of mortality and morbidity in the world, especially in developing countries. Drug therapy is one of the main ways to treat cardiovascular diseases. Among them, great progress has been made in the treatment of cardiovascular diseases with traditional Chinese medicine. In terms of experimental research, the mechanism of traditional Chinese medicine in the treatment of cardiovascular diseases has been thoroughly discussed in vitro and in vivo. In terms of clinical treatment, traditional Chinese medicine with flavonoids, saponins and alkaloids as the main effective components has a definite effect on the treatment of cardiovascular diseases such as arrhythmia, myocardial ischemia, angina pectoris and myocardial infarction, with high safety and good application prospects. With the further research on the effective ingredients, mechanism and adverse reactions of traditional Chinese medicine, it will be beneficial to the effectiveness of traditional Chinese medicine, reduce side effects and promote the modernization of traditional Chinese medicine. Calycosin and its derivatives, the main bioactive flavonoids in Astragalus membranaceus have multiple biological effects, such as antioxidant, pro-angiogenesis, anti-tumour, and anti-inflammatory effects. Based on the above biological effects, calycosin has been shown to have good potential for cardiovascular protection. The potent antioxidant effect of calycosin may play an important role in the cardiovascular protective potential. For injured cardiac myocytes, calycosin and its derivatives can alleviate the cell damage mainly marked by the release of myocardial enzymes and reduce the death level of cardiac myocytes mainly characterized by apoptosis through various mechanisms. For vascular endothelial cells, calycosin also has multiple effects and multiple mechanisms, such as promoting vascular endothelial cell proliferation, exerting vasodilating effect and directly affecting the synthesis function of endothelial cells. The present review will address the bioactivity of calycosin in cardiovascular diseases such as protective effects on cardiac myocytes and vascular endothelial cells and elucidate main mechanism of calycosin and its derivatives to exert the above biological effects.

Abstract
A sensitive anodic near-infrared electrochemiluminescence (ECL) immunosensor for the detection of tetracycline, based on Cu-doped CdTe quantum dots, was fabricated for the first time in this work. We have synthesized Cu-doped CdTe quantum dots by co-precipitation. The emission spectrum of the Cu-doped CdTe quantum dots could reach the near-infrared region at 730 nm in a short reflux time. More importantly, the ECL intensity of the CdTe quantum dots was enhanced by 2 fold after Cu element doping, which was attributed to the Cu d-orbital mixed with the conduction band and valence band of the host CdTe quantum dots. Inspired by the strong anodic ECL intensity of Cu-doped CdTe quantum dots, the anodic near infrared ECL sensor was constructed to detect tetracycline by competitive immunoassay. The detection range of the developed biosensor was 0.01-10 ng mL-1 and the detection limit was 0.0030 ng mL-1. In addition, the biosensor showed outstanding selectivity, long-term stability and high reproducibility, which has great potential in the field of analysis and detection.

Abstract
Background The initial symptoms of patients with COVID-19 are very much like those of patients with community-acquired pneumonia (CAP); it is difficult to distinguish COVID-19 from CAP with clinical symptoms and imaging examination. Objective The objective of our study was to construct an effective model for the early identification of COVID-19 that would also distinguish it from CAP. Methods The clinical laboratory indicators (CLIs) of 61 COVID-19 patients and 60 CAP patients were analyzed retrospectively. Random combinations of various CLIs (ie, CLI combinations) were utilized to establish COVID-19 versus CAP classifiers with machine learning algorithms, including random forest classifier (RFC), logistic regression classifier, and gradient boosting classifier (GBC). The performance of the classifiers was assessed by calculating the area under the receiver operating characteristic curve (AUROC) and recall rate in COVID-19 prediction using the test data set. Results The classifiers that were constructed with three algorithms from 43 CLI combinations showed high performance (recall rate >0.9 and AUROC >0.85) in COVID-19 prediction for the test data set. Among the high-performance classifiers, several CLIs showed a high usage rate; these included procalcitonin (PCT), mean corpuscular hemoglobin concentration (MCHC), uric acid, albumin, albumin to globulin ratio (AGR), neutrophil count, red blood cell (RBC) count, monocyte count, basophil count, and white blood cell (WBC) count. They also had high feature importance except for basophil count. The feature combination (FC) of PCT, AGR, uric acid, WBC count, neutrophil count, basophil count, RBC count, and MCHC was the representative one among the nine FCs used to construct the classifiers with an AUROC equal to 1.0 when using the RFC or GBC algorithms. Replacing any CLI in these FCs would lead to a significant reduction in the performance of the classifiers that were built with them. Conclusions The classifiers constructed with only a few specific CLIs could efficiently distinguish COVID-19 from CAP, which could help clinicians perform early isolation and centralized management of COVID-19 patients.

Abstract
Abstract MicroRNA (miRNA) belongs to a class of endogenous non-coding small RNA molecules with a length of 18-24 nucleotides. The expression of miRNA is highly conservative, has time sequence and is highly tissue-specific. MiRNA could not be easily degraded by ribonuclease, and is resistant to changes in environmental factors such as temperature and pH value. Moreover, miRNA can even be detected in corrupt tissue. As a result, miRNA has broad application prospects in many fields of forensic medicine such as source identification of body fluid and estimation of cause of death. This article briefly summarizes the application of miRNA in forensic practice, such as body fluid identification, determination of postmortem interval and cause of death analysis.

Abstract
Background To calculate the reference intervals for thyroid‐stimulating hormone (TSH) and thyroid hormones using the Access TSH 3rd IS method and evaluate the differences between age and genders in Chinese populations. Methods This study collected 349 serum samples of healthy subjects were from Shengli Oilfield Central Hospital in China. Subjects who tested positive for thyroid peroxidase antibody or thyroglobulin antibody were excluded. Accordingly, 313 subjects were included for establishing reference intervals for the thyroid hormones. The serum concentrations of TSH, total and free thyroxine (TT4 and FT4), and total and free triiodothyronine (TT3 and FT3) were measured using the Access TSH 3rd IS method. The 2.5th and 97.5th percentiles or mean with standard deviation were calculated as the reference interval as appropriate. Results The reference intervals for TSH, FT4, FT3, TT4, and TT3 calculated in present study were 0.61‐4.16 mIU/L, 0.67‐1.11 ng/dL, 2.63‐4.33 pg/mL, 5.56‐11.33 μg/dL, and 0.72‐1.32 ng/mL, respectively. The FT3, TT4, and TT3 levels in males were significantly higher than in females (P < .05), while TSH levels in males were significantly lower than in females (P < .05). The levels of FT3 in subjects with the age of less than 30 years were significantly higher than other groups (P < .05). Conclusion The present study provided a valid basis for the reference intervals for TSH, FT4, FT3, TT4, and TT3 in Chinese populations. In addition, this present study indicated that age and gender should be considered in diagnostic evaluation of thyroid diseases.

Abstract
Objective: To study the technical notes and clinical efficacy of full-endoscopic thoracic intervertebral discectomy via transforaminal approach. Methods: We included 16 patients with thoracic disc herniation treated by full-endoscopic thoracic discectomy via transforaminal approach between January 2017 and September 2018 in ours department of orthopedics. The average age is 53.7 years. The compressionare classified by nature: 5 cases of soft thoracic disc herniation, 7 cases of calcified or ossified thoracic disc herniation, and 4 cases of osteophyte protrusion of the posterior edge of the adjacent vertebral body of the diseased disc. All patients had symptoms of thoracic myelopathy before operation, and 7 of them had radiculopathy. Via transforaminal approach under local anesthesia, enlarged foraminoplasty and full-endoscopic thoracic discectomy were used for treatment. Observe the changes of postoperative imaging, pain symptoms and recovery of spinal cord function at 1 week, 3 months, 6 months and 1 year after operation. Back pain and radicular pain were scored with VAS, neurological function was assessed with Nurick score and mJOA score, and thoracic spine function was assessed with Oswestry disability index (ODI). Results: All operations were successfully completed, and no intraoperative conversion of surgical methods occurred. Postoperative thoracic MRI and CT examinations of all patients showed that the spinal cord was fully decompressed without any residual compression. Back pain and radicular pain were all relieved obviously in all patients, and spinal cord function was obviously restored. Transient intercostal neuralgia occurred in 2 cases after operation, and no other surgical complications occurred. Conclusions: Full-endoscopic or fluoroscopic foraminoplasty and full-endoscopic thoracic discectomyvia transforaminal approach under local anesthesia is a safe and effective treatment for soft and hard thoracic disc herniation located on the ventral side of the spinal cord.

Abstract
Gastric cancer (GC) is one of the most common malignancies of the digestive system worldwide. Multiple long noncoding RNAs (lncRNAs) participate in the regulation of GC development and metastasis. In this study, we aimed to elucidate the expression and function of lncRNA IGFL2-AS1 in GC. We found that IGFL2-AS1 was highly expressed in GC tissues and cell lines. Knockdown of IGFL2-AS1 suppressed GC cell proliferation, migration, and invasion in vitro. Furthermore, we identified that IGFL2-AS1 exerted its function as a molecular sponge of miR-802. MiR-802 was demonstrated to be a tumor suppressor, and overexpression of miR-802 suppressed GC cell growth, migration, and invasion. Mechanistically, we revealed that the cAMP-regulated phosphoprotein 19 (ARPP19) was a direct target of miR-802 and could reverse the inhibitory function of miR-802. Moreover, our results confirmed that knockdown of IGFL2-AS1 inhibited GC tumor development in an in vivo GC tumor xenograft model. In summary, our data suggest that the IGFL2-AS1/miR-802/ARPP19 axis plays a critical role in the progression and metastasis of GC. Therapies targeting the IGFL2-AS1/miR-802/ARPP19 axis can potentially improve GC treatment.

Abstract
Objective: To establish a nude mouse model of subcutaneous lung cancer using dual fluorescence reporting genes of luciferase (Luc) and near-infrared fluorescent protein (iRFP). Methods: The Luc and iRFP expressed lentiviral vector was constructed by Gateway method. After verified by sequencing, the lentivirus particle was prepared and infected into lung cancer A549 cells. Successfully infected A549 (mA549) cells were selected by puromycin and amplified. The expression of Luc and iRFP were observed under fluorescence microscope, and the expression of c-Met protein on the cell surface was detected by immunofluorescence. Twelve female nude mice were randomly divided into 2 groups, 6 in each group. A549 and mA549 cells were inoculated subcutaneously into the right forelimb of nude mice. The growth and fluorescence expression of the tumor were observed by in vivo imaging. The tumor formation was evaluated by hematoxylin-eosin (HE) staining and immunohistochemistry. Results: The Luc and iRFP stably expressed mA549 cell line was successfully constructed. The expressions of iRFP and Luc in mA549 cells were observed under fluorescence microscope. The results of immunofluorescence showed that c-Met protein expressed in both A549 cells and mA549 cells. The growth period of mA549 xenograft in nude mice was moderate and the tumorigenesis rate was 100%. The growth trend of mA549 cells in vivo was not significantly different from that of A549 cells (P>0.05). HE staining and immunohistochemistry results showed that the tumor issues displayed typical histopathological features of tumor. Immunohistochemistry results showed that both A549 and mA549 tumors expressed c-Met protein. Conclusion: A stable, real-time monitoring model of iRFP-Luc-A549 lung cancer cell xenograft in nude mice was successfully constructed.

Abstract
Objective:The aim of this study is to investigate the effects of rhodiola rosea on oxidative stress, anxiety and depression in patients with OSA. Method:Ninety patients with moderate and severe OSA patients with negative emotions diagnosed by PSG, self-rating depression scale (SDS) and self-rating anxiety scale (SAS) were selected from the respiratory department of our hospital from February 2015 to February 2018. According to the random number table method, the patients were randomly divided into non-invasive ventilator group, rhodiola rosea+non-invasive ventilator group and rhodiola rosea group, with 30 cases in each group. Patients in the non-invasive ventilator group were treated with continuous positive airway pressure (CPAP) for 3 months, and those in the rhodiola rosea+non-invasive ventilator group were treated with oral rhodiola capsules for 3 months on the basis of CPAP, and those in the rhodiola rosea treatment group were treated with pure oral rhodiola capsules for 3 months. The changes of SDS and SAS before and after the three groups were compared, and the changes of serum SOD and MDA were detected by immunoenzyme-linked adsorption for comparative analysis. Result:There were no significant differences in SDS and SAS scores between the three groups (P>0.05). SDS and SAS scores of patients in the rhodiola rosea+non-invasive ventilator group decreased after treatment (P<0.05) compared with those in the non-invasive ventilator group. SDS and SAS scores of patients in the rhodiola treatment group increased after treatment (P<0.05). Compared with those in the rhodiola treatment group, SDS and SAS scores of patients in the rhodiola+non-invasive breathing group decreased after treatment (P<0.05). Three group patients were no significant difference in serum SOD and malondialdehyde (MDA) before treatment (P>0.05). Compared with before treatment, serum SOD level were all increased and MDA level were all decreased in the three groups after treatment (P<0.05). Compared with noninvasive breathing unit after treatment, rhodiola+noninvasive breathing unit after treatment in patients with elevated levels of serum SOD, MDA level decreased (P<0.05), and for the treatment group after treatment in patients with serum SOD levels drop, the MDA levels (P<0.05), and the after rhodiola rosea treatment group compared, rhodiola+noninvasive breathing unit after treatment in patients with elevated levels of serum SOD, MDA level decreased (P<0.05). Conclusion:Rhodiola may improve the negative emotions such as anxiety and depression by inhibiting oxygen free radicals and lipid peroxidation in patients with OSA.

Abstract
Summary Vestibular disorders are a group of disorders that may result from damage to peripheral or central vestibular system, which seriously affect the patients' lives and work and even life-threatened. The causes of most vestibular disorders are still unclear, the auxiliary examination is not effective enough and the treatment is not individualized. It needs to improve the diagnosis and treatment efficiency of patients with vestibular disorders. Recent advance in artificial intelligence technology could provide novel promising strategies for the diagnosis and treatment of patients and assist clinical trials. Here we summarized the application of artificial intelligence technique in the field of vertigo, and look to the possible application in the future.

Abstract
Background & aims: Biopsy is the gold standard for staging liver fibrosis, but it may be accompanied by complications. As an alternative, non-invasive markers such as transient elastography (for liver fibrosis) and certain combinations of routine blood markers (liver function tests, full blood count) have been developed although their clinical significance remains controversial. Here, we compare the diagnostic values of non-invasive markers for liver fibrosis in patients with chronic hepatitis B infection. Methods: Transient elastography and routine laboratory tests were performed in 196 patients. Diagnostic performances were compared and were assessed based on the area under the curve (AUC) of a receiver operating characteristic (ROC) analysis. Results: Elevated GGT to platelet ratio (GPR), the fibrosis index FIB-4 [based on age, AST, platelets and ALT], platelet to lymphocyte ratio (PLR) and total bilirubin were independent predictors of liver stiffness defined by transient elastography (all P < 0.001). The AUCs of GPR in predicting both advanced fibrosis and cirrhosis were significantly larger than that of FIB-4 (P = 0.037 and P = 0.008, respectively) and AST-to-platelet ratio index (APRI) (P = 0.008 and P = 0.005). FIB-4, APRI and red cell volume distribution width-to-platelet ratio (RPR) had similar diagnostic values in discriminating different levels of liver fibrosis. Conclusions: GPR showed the best diagnostic value and RPR and PLR are easily available and inexpensive markers in evaluating fibrosis and cirrhosis. The diagnostic values of these laboratory markers are useful in diagnosing advanced fibrosis or cirrhosis, and in confirming the different levels of liver fibrosis.

The statistical analysis was conducted among 4 kinds of the most common causes of vertigo in children. There was no significant differences in sex composition among different groups(P>0.05). The mean age and mean age of onset in patients with BPVC were the youngest(P<0.05). Headache was complained more often in patients with VM(P<0.05) and there was no difference in other accompanying symptoms (such as nausea, vomiting and tinnitus) among each groups(P>0.05).Most patients with VM had family history of vertigo or migraine, but not in patients with VM and patients with BPVC(P>0.05). Conclusion:The most common vertigo in children were BPVC, VM and BPPV. The medical history, physical examinations and vestibular function tests can help doctors to diagnose more correctly.

Abstract
Epimedii Folium,a commonly used traditional Chinese medicine,has the effect of tonifying kidney Yang,strengthening bones and treating rheumatism. However,in recent years,the number of reports on adverse reactions of Epimedii Folium and its Chinese patent medicines such as Xianling Gubao Capsules and Zhuanggu Guanjie Pills has been gradually increased,and the toxicity of Epimedii Folium has attracted more and more attention. In this article,the ancient and modern literature on Epimedii Folium was traced through a comprehensive and systematic literature analysis method. According to the 2015 edition of the Chinese Pharmacopoeia,Epimedii Folium refers to the dried leaves of Epimedii Folium brevicomu,E. sugittutum,E. pubescens or E. koreuuum. The Chinese Pharmacopoeia also includes E. wushanense of Wushan Epimedium,which is the same plant variety as Epimedium. The study showed that there were differences in the geographical distribution,composition and toxicity among five species of Epimedium. This paper also explained the toxicity mechanism as well as efficacy enhancing and toxicity reducing effects of Epimedii Folium,and reported its related adverse reaction cases. Through a retrospective comparative study on the toxicity of the modern Chinese patent medicines Xianling Gubao Capsules and Zhuanggu Guanjie Pills containing Epimedii Folium,it was believed that Epimedii Folium had cardiovascular system toxicity,neurotoxicity,hepatotoxicity,long-term toxicity,acute toxicity,genotoxicity and special toxicity; its safe medication factors included patient syndrome,doctor factors,drug factors,processing and compatibility factors. Meanwhile,strategies were proposed to improve patient safety medication awareness,standardize Epimedii Folium varieties and quality supervision,and the toxicity of Epimedii Folium was studied,hoping to draw attention from scholars to the safety of Epimedii Folium,improve the safe use of Epimedii Folium,and prevent adverse reactions.

Abstract
OBJECTIVE To investigate the prognostic value of 18F-FDG PET/CT scan quantization parameters, max standardized uptake value (SUVmax), metabolic tumor volume (MTV), total lesion glycolysis (TLG) and other clinical factors for prognostic evaluation of paticnts with diffuse large B-cell lymphoma (DLBCL). METHODS PET/CT scan and clinical data of a total of 65 newly diagnosed DLBCL patients who received Rituximab plus cyclophosphamide, doxorubicin, vincristine and prednisone (R-CHOP) chemotherapy as first-line treatment were analyzed. All patients received a PET/CT scan at diagnosis and an interim PET/CT after 2-4 circles of chemotherapies. The related parameters of SUVmax, MTV and TLG were acquired by analyzing and calculating the scan results. The receiver operating characteristic (ROC) curve was used to determine the optimal cut-off of parameters. Pearson chi-square test, Kaplan-Meier method and COX proportional hazard model were performed to analyze the prognostic value of PET/CT related parameters and clinical factors in progression-free survival (PFS). RESULTS Age, B symptom, Ann Arbor stage and extra-nodal involvement in major organs significantly related with PFS (P<0.05), but the SUVmax didn't relalt with the prognosis. The cut-off values of MTV0, MTV1, TLG0 and TLG1 for disease recurrence or progression were 172.20cm 3, 4.32cm 3, 1043.33g and 14.07g. The lower MTV and TLG groups showed longer PFS significantly. In the multivariate Cox regression model, B symptoms, MTV1 and TLG1 were the independent prognostic risk factors. CONCLUSION MTV and TLG at baseline and in the interim and NCCN-IPI correlate with disease prognosis. SUVmax related parameters hare no significant relationship with prognosis. Besides MTV and TLG during treatment are the independent prognostic risk factors suggesting more predictive value than NCCN-IPI.

Abstract
Hog deer (Axis porcinus) is a small deer species in family Cervidae and has been undergoing a serious and global decline during the past decades. Chengdu Zoo currently holds a captive population of hog deer with sufficient genetic diversity in China. We sequenced and de novo assembled its genome sequence in the present study. A total of six different insert-size libraries were sequenced and generated 395 Gb of clean data in total. With aid of the linked reads of 10X Genomics, genome sequence was assembled to 2.72 Gb in length (contig N50, 66.04 Kb; scaffold N50, 20.55 Mb), in which 94.5% of expected genes were detected. We comprehensively annotated 22,473 protein-coding genes, 37,019 tRNAs, and 1,058 Mb repeated sequences. The newly generated reference genome is expected to significantly contribute to comparative analysis of genome biology and evolution within family Cervidae.

Abstract
Background Chimeric antigen receptor (CAR) T cell therapy has demonstrated proven efficacy in some hematologic cancers. We evaluated the safety and efficacy of LCAR-B38M, a dual epitope-binding CAR T cell therapy directed against 2 distinct B cell maturation antigen epitopes, in patients with relapsed/refractory (R/R) multiple myeloma (MM). Methods This ongoing phase 1, single-arm, open-label, multicenter study enrolled patients (18 to 80 years) with R/R MM. Lymphodepletion was performed using cyclophosphamide 300 mg/m2. LCAR-B38M CAR T cells (median CAR+ T cells, 0.5 × 106 cells/kg [range, 0.07 to 2.1 × 106]) were infused in 3 separate infusions. The primary objective is to evaluate the safety of LCAR-B38M CAR T cells; the secondary objective is to evaluate the antimyeloma response of the treatment based on the general guidelines of the International Myeloma Working Group. Results At data cutoff, 57 patients had received LCAR-B38M CAR T cells. All patients experienced ≥ 1 adverse events (AEs). Grade ≥ 3 AEs were reported in 37/57 patients (65%); most common were leukopenia (17/57; 30%), thrombocytopenia (13/57; 23%), and aspartate aminotransferase increased (12/57; 21%). Cytokine release syndrome occurred in 51/57 patients (90%); 4/57 (7%) had grade ≥ 3 cases. One patient reported neurotoxicity of grade 1 aphasia, agitation, and seizure-like activity. The overall response rate was 88% (95% confidence interval [CI], 76 to 95); 39/57 patients (68%) achieved a complete response, 3/57 (5%) achieved a very good partial response, and 8/57 (14%) achieved a partial response. Minimal residual disease was negative for 36/57 (63%) patients. The median time to response was 1 month (range, 0.4 to 3.5). At a median follow-up of 8 months, median progression-free survival was 15 months (95% CI, 11 to not estimable). Median overall survival for all patients was not reached. Conclusions LCAR-B38M CAR T cell therapy displayed a manageable safety profile and demonstrated deep and durable responses in patients with R/R MM.

Abstract
OBJECTIVE To prepare ion exchange doxorubicin-loaded poly (acrylic acid) microspheres (DPMs) and evaluate the properties of these chemoembolic agents. METHODS Poly (acrylic acid) microspheres (PMs) without drug were prepared by inverse suspension polymerization method and then doxorubicin was loaded by ion exchange mechanism to prepare DPMs. Optical microscope was used to investigate the morphology and particle size distribution of PMs and DPMs; fluorescence microscope and confocal microscope were used to observe the distribution of doxorubicin after drug loading. Elasticities of both the microspheres were evaluated by texture analyzer. High performance liquid chromatography (HPLC) method was established to determine the drug loading behavior of PMs and releasing behavior of DPMs. The in vivo embolic property was evaluated by embolizing the hepatic artery of a rabbit with 0.1 mL of DPMs. RESULTS PMs and DPMs were both spherical in shape, smooth in surface and dispersed well. Doxorubicin was mainly in the outer area inside of DPMs and distributed evenly. The average particle size of PMs and DPMs were (283±136) μm and (248±149) μm, respectively. PMs and DPMs both had good compression ability with the Young's modulus of (62.63±1.65) kPa and (93.94±1.10) kPa separately. PMs reached the drug loading balance at 12 h, and the entrapment efficiency was greater than 99%. Drug loading of PMs in doxorubicin solution at the concentration of 5.0 g/L and 12.5 g/L was (19.78±0.27) g/L and (49.45±0.37) g/L, respectively. Doxorubicin released slowly from DPMs in PBS and the accumulative release percentages of DPMs with corresponding drug loading were 6.82%±0.02% and 2.83%±0.10% after 24 h, respectively. Arterial angiograms showed that the hepatic artery of the rabbit was successfully embolized with DPMs. CONCLUSION DPMs with good performance of loading doxorubicin could be a potential embolic agent for transcatheter arterial chemoembolization.
