Abstract
OBJECTIVE Intervertebral disk degeneration (IVDD) is one of the most common causes of low back pain. However, in the etiology of IVDD, the specific method by which nucleus pulposus (NP) cell senescence and the immune response induce disease is uncertain. METHODS Gene Expression Omnibus database was used to find differentially expressed genes (DEGs), differentially expressed miRNAs (DE miRNAs), differentially expressed lncRNAs (DE lncRNAs), and differentially expressed circRNAs (DE circRNAs). Functional enrichment analysis was performed through Enrichr database. Potential regulatory miRNAs, lncRNAs and circRNAs of mRNAs were predicted by ENCORI and circBank, respectively. RESULTS We identified 198 upregulated and 131 downregulated genes, 39 upregulated and 22 downregulated miRNAs, 2152 upregulated and 564 downregulated lncRNAs, and 352 upregulated and 279 downregulated circRNAs as DEGs, DE miRNAs, DE lncRNAs, DE circRNAs, respectively. Functional enrichment analysis revealed that they were significantly enriched in Toll-like receptor signaling route and the NF-kappa B signaling pathway. An mRNA-miRNA-lncRNA/circRNA network linked to the pathogenesis of NP cells in IVDD was constructed based on node degree and differential expression level. Eight immune-related DEGs (6 upregulated and 2 downregulated genes) and five aging-related DEGs (3 upregulated and 2 downregulated genes) were identified in the critical network. CONCLUSION We established a novel immune-related and aging-related triple regulatory network of mRNA-miRNA-lncRNA/circRNA ceRNA, among which all RNAs may be utilized as the pathogenesis biomarker of NP cells in IVDD.

Abstract
Ferroptosis has recently been shown to play a significant role in the progression of intervertebral disk degeneration (IDD), although the underlying mechanism is still unknown. The objective of this work was to use stringent bioinformatic techniques to clarify the crucial roles played by genes associated with ferroptosis in the emergence of IDD. For additional study, the microarray data pertinent to the IDD were acquired from the Gene Expression Omnibus database. The ferroptosis-related and IDD-related genes (FIDDRGs) were identified using a variety of bioinformatic techniques, which were also used to carry out function enrichment analysis, protein-protein correlation analysis, build the correlation regulatory network, and examine the potential connections between ferroptosis and immune abnormalities and inflammatory responses in IDD. A total of 16 FIDDRGs were eliminated for the further function enrichment analysis, and 10 hub FIDDRGs were chosen to build the correlation regulatory network. Hub FIDDRGs were shown to be highly associated with M2 macrophages and hub inflammatory response-related genes in IDD. When seen as a whole, our findings can give fresh perspectives on the mechanistic studies of ferroptosis in the emergence of IDD and new prospective targets for the therapeutic approaches.

Abstract
OBJECTIVE Little is known about the efficacy and safety of exercise training on juvenile idiopathic arthritis (JIA). This study aims to investigate the effect of exercise on health, quality of life, and different exercise capacities in individuals with JIA. METHOD A comprehensive search of Medline, Embase, Web of Science, and the Cochrane Library was conducted from database inception to October, 2023. Included studies were randomized controlled trials (RCTs) reporting the effects of exercise on JIA patients. Two independent reviewers assessed the literature quality using the Cochrane Collaboration's risk of bias tool. Standardized mean differences (SMD) were combined using random or fixed effects models. The level of evidence was assessed using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach. RESULT Five RCTs met the inclusion criteria, containing 216 female participants and 90 males. The meta-analysis results showed that exercise had no significant effect on JIA patients based on the Child Health Assessment Questionnaire (CHAQ) (SMD=-0.32, 95%CI: -0.83, 0.19; I2 = 73.2%, P = 0.011) and Quality of Life (QoL) (SMD = 0.27, 95%CI: -0.04, 0.58; I2 = 29.4%, P = 0.243) and no significant effect on peak oxygen uptake (VO2peak). However, exercise significantly reduced visual analog scale (VAS) pain scores in JIA patients (SMD = 0.50, 95%CI: -0.90, -0.10; I2 = 50.2%, P = 0.134). The quality of evidence assessed by GRADE was moderate to very low. CONCLUSION Exercise does not significantly affect the quality of life and exercise capacity in JIA patients but may relieve pain. More RCTs are needed in the future to explore the effects of exercise on JIA.

Abstract
Caffeic acid (CA)-derived phenethyl ester (CAPE) and phenethyl amide (CAPA) are extensively investigated bioactive compounds with therapeutic applications such as antioxidant, anti-inflammatory, and anticarcinogenic properties. To construct microbial cell factories for production of CAPE or CAPA is a promising option given the limitation of natural sources for product extraction and the environmental toxicity of the agents used in chemical synthesis. We reported the successful biosynthesis of caffeic acid in yeast previously. Here in this work, we further constructed the downstream synthetic pathways in yeast for biosynthesis of CAPE and CAPA. After combinatorial engineering of yeast chassis based on the rational pathway engineering method and library-based SCRaMbLE method, we finally obtained the optimal strains that respectively produced 417 μg/L CAPE and 1081 μg/L CAPA. Two screened gene targets of ΔHAM1 and ΔYJL028W were discovered to help improve the product synthesis capacity. This is the first report of the de novo synthesis of CAPA from glucose in an engineered yeast chassis. Future work on enzyme and chassis engineering will further support improving the microbial cell factories for the production of CA derivatives.

Abstract
Amino acids along the conformational motion pathway of the enzyme molecule correlated to its flexibility and rigidity. To enhance the enzyme activity and thermal stability, the motion pathway of Geobacillus stearothermophilus α-amylase has been identified and molecularly modified by using the neural relational inference model and deep learning tool. The significant differences in substrate specificity, enzymatic kinetics, optimal temperature, and thermal stability were observed among the mutants with modified amino acids along the pathway. Mutants especially the P44E demonstrated enhanced hydrolytic activity and catalytic efficiency (kcat/KM) than the wild-type enzyme to 95.0% and 93.8% respectively, with the optimum temperature increased to 90°C. This mutation from proline to glutamic acid has increased the number and the radius of the bottleneck of the channels, which might facilitate transporting large starch substrates into the enzyme. The mutation could also optimize the hydrogen bonding network of the catalytic center, and diminish the spatial hindering to the substrate entry and exit from the catalytic center.

Abstract
Porosity is a crucial quality evaluation criterion in metal additive manufacturing. To investigate the propagation characteristics of ultrasonic longitudinal waves with different incident frequencies in AlSi10Mg prepared by selective laser melting, specimens with varying porosity were created using printing process adjustments. Ultrasonic longitudinal wave tests and COMSOL simulations based on 2.5 MHz, 3.5 MHz, 5 MHz, and 7.5 MHz incident frequencies were carried out to establish a linear relationship between average wave velocity, average attenuation coefficient, and porosity at different frequencies. Results indicate that sound velocity and porosity are inversely proportional for each frequency longitudinal wave, while the attenuation coefficient is proportional to the porosity. Linear fitting expressions suggest that the best fit for both sound velocity and attenuation coefficient occurs at 5 MHz. Simulation results demonstrate that using 5 MHz as the incident frequency can better balance detection sensitivity and linearity. These findings provide more data support for establishing the intrinsic connection between acoustic parameters and porosity of AlSi10Mg prepared by selective laser melting in the selected area and serve as a reference for selecting ultrasonic incident frequencies in practical inspection.

Abstract
The prevalence and clinical correlates of antibiotic resistance genes (ARGs) in bronchiectasis are not entirely clear. We aimed to profile the ARGs in sputum from adults with bronchiectasis, and explore the association with airway microbiome and disease severity and subtypes. In this longitudinal study, we prospectively collected 118 sputum samples from stable and exacerbation visits of 82 bronchiectasis patients and 19 healthy subjects. We profiled ARGs with shotgun metagenomic sequencing, and linked these to sputum microbiome and clinical characteristics, followed by validation in an international cohort. We compared ARG profiles in bronchiectasis according to disease severity, blood and sputum inflammatory subtypes. Unsupervised clustering revealed a Pseudomonas predominant subgroup (n = 16), Haemophilus predominant subgroup (n = 48), and balanced microbiome subgroup (N = 54). ARGs of multi-drug resistance were over-dominant in the Pseudomonas-predominant subgroup, while ARGs of beta-lactam resistance were most abundant in the Haemophilus-predominant subgroup. Pseudomonas-predominant subgroup yielded the highest ARG diversity and total abundance, while Haemophilus-predominant subgroup and balanced microbiota subgroup were lowest in ARG diversity and total abundance. PBP-1A, ksgA and emrB (multidrug) were most significantly enriched in Haemophilus-predominant subtype. ARGs generally correlated positively with Bronchiectasis Severity Index, fluoroquinolone use, and modified Reiff score. 68.6% of the ARG-clinical correlations could be validated in an independent international cohort. In conclusion, ARGs are differentially associated with the dominant microbiome and clinical characteristics in bronchiectasis.

Abstract
Pulmonary arterial hypertension (PH) is a chronic disease induced by a progressive increase in pulmonary vascular resistance and failure of the right heart function. A number of studies show that the development of PH is closely related to the gut microbiota, and lung-gut axis might be a potential therapeutic target in the PH treatment. A. muciniphila has been reported to play a critical role in treating cardiovascular disorders. In this study we evaluated the therapeutic effects of A. muciniphila against hypoxia-induced PH and the underlying mechanisms. Mice were pretreated with A. muciniphila suspension (2 × 108 CFU in 200 μL sterile anaerobic PBS, i.g.) every day for 3 weeks, and then exposed to hypoxia (9% O2) for another 4 weeks to induce PH. We showed that A. muciniphila pretreatment significantly facilitated the restoration of the hemodynamics and structure of the cardiopulmonary system, reversed the pathological progression of hypoxia-induced PH. Moreover, A. muciniphila pretreatment significantly modulated the gut microbiota in hypoxia-induced PH mice. miRNA sequencing analysis reveals that miR-208a-3p, a commensal gut bacteria-regulated miRNA, was markedly downregulated in lung tissues exposed to hypoxia, which was restored by A. muciniphila pretreatment. We showed that transfection with miR-208a-3p mimic reversed hypoxia-induced abnormal proliferation of human pulmonary artery smooth muscle cells (hPASMCs) via regulating the cell cycle, whereas knockdown of miR-208a-3p abolished the beneficial effects of A. muciniphila pretreatment in hypoxia-induced PH mice. We demonstrated that miR-208a-3p bound to the 3'-untranslated region of NOVA1 mRNA; the expression of NOVA1 was upregulated in lung tissues exposed to hypoxia, which was reversed by A. muciniphila pretreatment. Furthermore, silencing of NOVA1 reversed hypoxia-induced abnormal proliferation of hPASMCs through cell cycle modulation. Our results demonstrate that A. muciniphila could modulate PH through the miR-208a-3p/NOVA1 axis, providing a new theoretical basis for PH treatment.

Abstract
Objective: To explore the feasibility and value of performing a three-sided encapsulation procedure based on fascia anatomy in laparoscopic lateral lymph node dissection (LLND) for middle and low rectal cancer. Methods: This was a retrospective review. The study cohort comprised patients who met the diagnostic criteria for rectal cancer according to the Chinese Guidelines for the Diagnosis and Treatment of Colorectal Cancer, had a short lymph node diameter of >5 mm on the lateral side within the 15 days before surgery, were evaluated as feasible candidates for laparoscopic total mesorectal excision+LLND surgery, had been diagnosed with low or intermediate level rectal cancer, and whose tumor was less than 8 cm away from the anal verge according to pathological examination of the operative specimen. Patients with a history of other malignant tumors of the abdomen or with incomplete follow-up data were excluded. Forty-two patients with middle and low rectal cancer who had undergone lateral lymph node dissection in diagnosis and treatment center of Gastrointestinal Cancer of Guangdong Hospital of Chinese Medicine from Jan.2018 to Dec.2022 were enrolled. There were 24 men (57.1%) and 18 women (42.9%) aged 58.4±11.8 years and the median BMI was 22.5 (19.3-24.1) kg/m2. The main point of the three-sided encapsulation procedure is to expand the external side medial to the external iliac artery and vein, narrowing the range of exterior side dissection. The anterior-medial side is designed to expand the vesical fascia to define the range of anterior-medial side extension. The internal side is fully extended to the ureterohypogastric nerve fascia; the distal point of the caudal extension reaches the level of the Alcock canal and the bottom reaches the piriformis, enabling dissection of the obturator nerve and No.283 lymph nodes. No.263D lymph nodes are dissected by exposing the internal iliac artery and its branches, dissecting the group No.263P lymph nodes, and severing the inferior vesical artery. Finally, the lateral lymphatic tissue is completely resected. Relevant variables were recorded, including the number of lateral lymph nodes detected, the rate of lymph node metastasis, operation duration, intraoperative blood loss, postoperative complications, postoperative hospital stay, and 3-year overall survival rate. Results: Laparoscopic surgery was successfully completed in all patients with no conversions to open surgery and no intraoperative complications. Twenty-seven (64.3%) of the study patients underwent left-sided LLND, 10 (23.8%) right-sided LLND, and five (11.9%) bilateral LLND, with lymph nodes cleared on both sides. All patients' lymph nodes were examined pathologically. A median of 17.0 (11.7, 26.0) lymph nodes was detected, the median of lateral lymph nodes being 5.0 (2.0, 10.2). The median operation time was 254.5 (199.0, 325.2) minutes. The median intra-operative blood loss was 50.0 (30.0, 100.0) mL. All patients were diagnosed with adenocarcinoma by pathological examination of the operative specimen. Two patients developed postoperative intestinal obstruction, one lymphatic leakage, and one a perineal incision infection. There were no cases of anastomotic leakage. The median postoperative hospital stay was 6.0 (5.0, 7.0) days and the median follow-up time 23.5 (9.0, 36.7) months. During follow-up, three patients (7.1%) died of tumor recurrence and metastasis. Two (4.8%) experienced mild urinary dysfunction, and one (2.4%) had moderate postoperative erectile dysfunction. One patient (2.4%) was found to have prostate and lung metastases 3 month after surgery. The 3-year overall survival rate was 74.4%. Conclusions: Three sided encapsulation is a safe and feasible procedure for LLND, achieving accurate and complete clearance of lateral lymphatic tissue.

Abstract
In this work, a series of 2-(trifluoromethyl)quinolin-4-amine derivatives were designed and synthesized through structural optimization strategy as a microtubule-targeted agents (MTAs) and their cytotoxicity activity against PC3, K562 and HeLa cell lines were evaluated. The half maximal inhibitory concentration (IC50) of 5e, 5f, and 5o suggested that their potency of anti-proliferative activities against HeLa cell lines were better than the combretastatin A-4. Compound 5e showed the higher anti-proliferative activity against PC3, K562 and HeLa in vitro with IC50 values of 0.49 µM, 0.08 µM and 0.01 µM, respectively. Further mechanism study indicated that the representative compound 5e was new class of tubulin inhibitors by EBI competition assay and tubulin polymerization assays, it is similar to colchicine. Immunofluorescence staining revealed that compound 5e apparently disrupted tubulin network in HeLa cells, and compound 5e arrested HeLa cells at the G2/M phase and induced cells apoptosis in a dose-dependent manner. Molecular docking results illustrated that the hydrogen bonds of represented compounds reinforced the interactions in the pocket of colchicine binding site. Preliminary results suggested that 5e deserves further research as a promising tubulin inhibitor for the development of anticancer agents.

Abstract
Purpose To inveatigate how effective LMWH was at preventing venous thromboembolism (VTE), major bleeding events, and minor bleeding events after simple knee arthroscopic surgery and anterior cruciate ligament reconstruction (ACLR). Methods We conducted a comprehensive search of PubMed, EMBASE, Cochrane Library, and the CNKI database for potentially eligible articles. The outcomes were evaluated in terms of odds ratio (OR) and the associated 95% confidence intervals (CIs). Meta-analysis was performed using the Stata software and subgroup analyses were performed based on the surgical setting including ACLR and simple knee arthroscopic surgery. Results A total of eight studies with 2249 patients and 1794 controls were included in this meta-analysis. In patients undergoing simple knee arthroscopic surgery, LMWH prophylaxis did not bring a significant reduction in the risk of symptomatic deep venous thrombosis (DVT), symptomatic pulmonary embolism (PE), symptomatic VTE, and did not increase the risk of major bleeding events, but did have a higher risk of minor bleeding events (OR = 1.95, 95% CI 1.34-2.84, P = 0.000) and a lower risk of asymptomatic DVT (OR = 0.14, 95% CI 0.04-0.53, P = 0.004) in comparison with non-LMWH prophylaxis. In patients undergoing ACLR, LMWH prophylaxis did not bring a significant reduction in the risk of symptomatic DVT, symptomatic PE, symptomatic VTE, and did not increase the risk of major bleeding events and minor bleeding events, but did have a lower risk of asymptomatic DVT (OR = 0.43, 95% CI 0.23-0.78, P = 0.006). Conclusion When compared to a control group, this meta-analysis found that LMWH had little potential benefit in preventing major VTE (symptomatic VTE, symptomatic DVT, and symptomatic PE) after simple knee arthroscopy and ACLR. As a result, LMWH should not be considered routinely in patients undergoing knee arthroscopic surgery.

Abstract
2'-deoxyguanosine is a key medicinal intermediate that could be used to synthesize anti-cancer drug and biomarker in type 2 diabetes. In this study, an enzymatic cascade using thymidine phosphorylase from Escherichia coli (EcTP) and purine nucleoside phosphorylase from Brevibacterium acetylicum (BaPNP) in a one-pot whole cell catalysis was proposed for the efficient synthesis of 2'-deoxyguanosine. BaPNP was semi-rationally designed to improve its activity, yielding the best triple variant BaPNP-Mu3 (E57A/T189S/L243I), with a 5.6-fold higher production of 2'-deoxyguanosine than that of wild-type BaPNP (BaPNP-Mu0). Molecular dynamics simulation revealed that the engineering of BaPNP-Mu3 resulted in a larger and more flexible substrate entrance channel, which might contribute to its catalytic efficiency. Furthermore, by coordinating the expression of BaPNP-Mu3 and EcTP, a robust whole cell catalyst W05 was created, capable of producing 14.8 mM 2'-deoxyguanosine (74.0% conversion rate) with a high time-space yield (1.32 g/L/h) and therefore being very competitive for industrial applications.

Abstract
Objective: To investigate low-frequency fluctuation amplitude changes in resting-state brain fMRI and its correlation with clinical hearing levels in patients with clinical hearing level in patients with unilateral hearing impairment. Methods: Forty-five patients with unilateral hearing impairment[12 males and 33 females, aged 36-67 (46.0±9.7) years], and 31 controls with normal hearing[9 males and 22 females, aged 36-67 (46.0±10.1) years], were retrospectively included. All subjects underwent blood oxygen level-dependent (BOLD) resting-state functional magnetic resonance imaging and high-resolution T1-weighted imaging. The patients were divided into the left-sided hearing impaired group(24 cases), and the right-sided hearing impaired group(21 cases). After data being preprocessed, differences in low frequency amplitude (ALFF) metrics between the evaluated patients and controls were calculated and analyzed, and the statistics were corrected for Gaussian random field (GFR). Results: Overall comparative analysis of patients with hearing impairment showed that one-way ANOVA among the three groups showed abnormal ALFF values only in the right anterior cuneiform lobe (GRF adjusted P=0.002). The ALFF value of the hearing impaired group was higher than that of the control group in one cluster (peak coordinates: X=9, Y=-72, Z=48, T=5.82), involving the left occipital gyrus, right anterior cuneiform lobe, left superior cuneiform lobe, left superior parietal gyrus, and left angular gyrus (GRF adjusted P=0.031). The ALFF value of the hearing impaired group was lower than that of the control group in three clusters (peak coordinates: X=57, Y=-48, Z=-24; T=-4.99; X=45, Y=-66, Z=0, T=-4.06; X=42, Y=-12, Z=36, T=-4.03), involving the right inferior temporal gyrus, the right middle temporal gyrus, and the right precentral gyrus (GRF adjusted P=0.009). Compared with the control group, the ALFF value of the left hearing impairment group was significantly higher than that of the control group in one cluster (peak coordinates: X=-12, Y=-75, Z=45, T=5.78), involving the left anterior cuneiform lobe, right anterior cuneiform lobe, left middle occipital gyrus, left superior parietal gyrus, left superior occipital gyrus, left cuneiform lobe, and right cuneiform lobe (P=0.023 after GRF correction). Compared with the control group, the right hearing impairment group had a significantly higher ALFF value in one cluster (peak coordinates: X=9, Y=-46, Z=22, T=6.06), involving the left middle occipital gyrus, right anterior cuneiform lobe, left cuneiform lobe, right cuneiform lobe, left superior occipital gyrus, and right superior occipital gyrus (GRF adjusted P=0.022); The brain area with reduced ALFF values is located in the right inferior temporal gyrus (GRF adjusted P=0.029). Spearman's two-tailed correlation analysis between ALFF values and pure tone average in the abnormal brain regions showed that ALFF values in the abnormal brain regions correlated to some extent with the pure tone average (PTA) only in the left-sided hearing impaired group(PTA=2 000 Hz, r=0.318,P=0.033;PTA=4 000 Hz,r=0.386,P=0.009). Conclusion: The abnormal neural activity within the brain are different in patients with left-sided and right-sided hearing impairment, and the severity of hearing impairment is related to the difference in functional integration of brain regions.

Abstract
Proprotein convertase subtilisin/kexin type 9 (PCSK9) has been demonstrated to play a critical role in regulating cholesterol homeostasis and T cell antitumor immunity. However, the expression, function, and therapeutic value of PCSK9 in head and neck squamous cell carcinoma (HNSCC) remain largely unexplored. Here, we found that the expression of PCSK9 was upregulated in HNSCC tissues, and higher PCSK9 expression indicated poorer prognosis in HNSCC patients. We further found that pharmacological inhibition or siRNA downregulating PCSK9 expression suppressed the stemness-like phenotype of cancer cells in an LDLR-dependent manner. Moreover, PCSK9 inhibition enhanced the infiltration of CD8+ T cells and reduced the myeloid-derived suppressor cells (MDSCs) in a 4MOSC1 syngeneic tumor-bearing mouse model, and it also enhanced the antitumor effect of anti-PD-1 immune checkpoint blockade (ICB) therapy. Together, these results indicated that PCSK9, a traditional hypercholesterolemia target, may be a novel biomarker and therapeutic target to enhance ICB therapy in HNSCC.

Abstract
Upper respiratory tract infection (URTI) is common in humans. We sought to profile sputum pathogen spectrum and impact of URTI on acute exacerbation of bronchiectasis (AE). Between March 2017 and December 2021, we prospectively collected sputum from adults with bronchiectasis. We stratified AEs into events related (URTI-AE) and unrelated to URTI (non-URTI-AE). We captured URTI without onset of AE (URTI-non-AE). We did bacterial culture and viral detection with polymerase chain reaction, and explored the pathogen spectrum and clinical impacts of URTI-AE via longitudinal follow-up. Finally, we collected 479 clinically stable samples, 170 AE samples (89 collected at URTI-AE) and 113 URTI-non-AE samples. The viral detection rate was significantly higher in URTI-AE (46.1%) than in non-URTI-AE (4.9%) and URTI-non-AE (11.5%) (both P<0.01). Rhinovirus [odds ratio (OR): 5.00, 95% confidence interval (95%CI): 1.06-23.56, P=0.03] detection was independently associated with URTI-AE compared with non-URTI-AE. URTI-AE tended to yield higher viral load and detection rate of rhinovirus, metapneumovirus and bacterial shifting compared with URTI-non-AE. URTI-AE was associated with higher initial viral loads (esp. rhinovirus, metapneumovirus), greater symptom burden (consistently higher scores of three validated questionnaires) and prolonged recovery compared to those without. Having experienced URTI-AE predicted greater risk of future URTI-AE (OR: 10.90, 95%CI: 3.60-33.05). In summary, URTI is associated with a distinct pathogen spectrum and aggravates bronchiectasis exacerbation, providing the scientific rationale for the prevention of URTI to hinder bronchiectasis progression.

Objective: To investigate the predictive factors for bronchitis obliterans in refractory Mycoplasma pneumoniae pneumonia (RMPP). Methods: A restrospective case summary was conducted 230 patients with RMPP admitted to the Department of No.2 Respiratory Medicine of Beijing Children's Hospital, Capital Medical University from January 2013 to June 2017 were recruited. Clinical data, laboratory results, imaging results and follow-up data were collected. Based on bronchoscopy and imaging findings 1 year after discharge, all patients were divided into two groups: one group had sequelae of bronchitis obliterans (sequelae group) and the other group had not bronchitis obliterans (control group), independent sample t-test and nonparametric test were used to compare the differences in clinical features between the two groups. Receiver operating characteristic (ROC) curve to explore the predictive value of Bronchitis Obliterans in RMPP. Results: Among 230 RMPP children, there were 115 males and 115 females, 95 cases had sequelae group, the age of disease onset was (7.1±2.8) years;135 cases had control group, the age of disease onset was (6.8±2.7) years. The duration of fever, C-reative protein (CRP) and lactate dehydrogenase (LDH) levels, the proportion of ≥2/3 lobe consolidation, pleural effusion and the proportion of airway mucus plug and mucosal necrosis were longer or higher in the sequelae group than those in the control group ((17±9) vs. (12±3) d, (193±59) vs. (98±42) mg/L,730 (660, 814) vs. 486 (452, 522) U/L, 89 cases (93.7%) vs. 73 cases (54.1%), 73 cases (76.8%) vs.59 cases (43.7%), 81 cases (85.3%) vs. 20 cases (14.8%), 67 cases (70.5%) vs. 9 cases (6.7%), t=5.76, 13.35, Z=-6.41, χ2=14.64, 25.04, 22.85, 102.78, all P<0.001). Multivariate Logistic regression analysis showed that the duration of fever ≥10 days (OR=1.200, 95%CI 1.014-1.419), CRP levels increased (OR=1.033, 95%CI 1.022-1.044) and LDH levels increased (OR=1.001, 95%CI 1.000-1.003) were the risk factors for sequelae of bronchitis obliterans in RMPP. ROC curve analysis showed that CRP 137 mg/L had a sensitivity of 82.1% and a specificity of 80.1%; LDH 471 U/L had a sensitivity of 62.7% and a specificity of 60.3% for predicting the development of bronchitis obliterans. Conclusions: The long duration of fever (≥10 d), CRP increase (≥137 mg/L) may be used to predict the occurrence of sequelae of bronchitis obliterans in RMPP. It is helpful for early recognition of risk children.

Abstract
Odorant receptors (ORs) in insects are crucial for the detection of chemical signals. However, the functions of the conserved OR genes among insect species are rarely studied. In this study, we analyzed a well-conserved OR clade in Diptera insects and cloned a gene from this clade, EcorOR4, in the hoverfly Eupeodes corollae. Real-time quantitative PCR showed that EcorOR4 was highly expressed in the antennae and upregulated in the mated females, and in vitro functional characterization showed that EcorOR4 was narrowly tuned to 1-octen-3-ol. Electroantennogram assays revealed that the antennal response of mated females to 1-octen-3-ol was significantly higher than that of mated males, but no significant differences were observed between male and female virgins. Finally, a Y-tube olfactometer bioassay showed that 1-octen-3-ol is an attractant for only mated female E. corollae adults. These results demonstrate that EcorOR4 is involved in the detection of 1-octen-3-ol and that this compound may affect the host-finding and oviposition behavior in female E. corollae.

Abstract
This study aimed to explore the potential mechanism of Berberis atrocarpa Schneid. anthocyanin against Alzheimer's disease(AD) based on network pharmacology, molecular docking technology, and in vitro experiments. Databases were used to screen out the potential targets of the active components of B. atrocarpa and the targets related to AD. STRING database and Cytoscape 3.9.0 were adopted to construct a protein-protein interaction(PPI) network and carry out topological analysis of the common targets. Gene Ontology(GO) and Kyoto Encyclopedia of Genes and Genomes(KEGG) enrichment analyses were performed on the target using the DAVID 6.8 database. Molecular docking was conducted to the active components and targets related to the nuclear factor kappa B(NF-κB)/Toll-like receptor 4(TLR4) pathway. Finally, lipopolysaccharide(LPS) was used to induce BV2 cells to establish the model of AD neuroinflammation for in vitro experimental validation. In this study, 426 potential targets of active components of B. atrocarpa and 329 drug-disease common targets were obtained, and 14 key targets were screened out by PPI network. A total of 623 items and 112 items were obtained by GO functional enrichment analysis and KEGG pathway enrichment analysis, respectively. Molecular docking results showed that NF-κB, NF-κB inhibitor(IκB), TLR4, and myeloid differentiation primary response 88(MyD88) had good binding abilities to the active components, and malvidin-3-O-glucoside had the strongest binding ability. Compared with the model group, the concentration of nitric oxide(NO) decreased at different doses of malvidin-3-O-glucoside without affecting the cell survival rate. Meanwhile, malvidin-3-O-glucoside down-regulated the protein expressions of NF-κB, IκB, TLR4, and MyD88. This study uses network pharmacology and experimental verification to preliminarily reveal that B. atrocarpa anthocyanin can inhibit LPS-induced neuroinflammation by regulating the NF-κB/TLR4 signaling pathway, thereby achieving the effect against AD, which provides a theoretical basis for the study of its pharmacodynamic material basis and mechanism.

Abstract
Heart aging is characterized by left ventricular hypertrophy and diastolic dysfunction, which in turn induces a variety of cardiovascular diseases. There is still no therapeutic drug to ameliorate cardiac abnormities in heart aging. In this study we investigated the protective effects of berberine (BBR) and its derivative tetrahydroberberrubine (THBru) against heart aging process. Heart aging was induced in mice by injection of D-galactose (D-gal, 120 mg · kg-1 · d-1, sc.) for 12 weeks. Meanwhile the mice were orally treated with berberine (50 mg · kg-1 · d-1) or THBru (25, 50 mg · kg-1 · d-1) for 12 weeks. We showed that BBR and THBru treatment significantly mitigated diastolic dysfunction and cardiac remodeling in D-gal-induced aging mice. Furthermore, treatment with BBR (40 μM) and THBru (20, 40 μM) inhibited D-gal-induced senescence in primary neonatal mouse cardiomyocytes in vitro. Overall, THBru exhibited higher efficacy than BBR at the same dose. We found that the levels of mitophagy were significantly decreased during the aging process in vivo and in vitro, THBru and BBR promoted mitophagy with different potencies. We demonstrated that the mitophagy-inducing effects of THBru resulted from increased mRNA stability of prohibitin 2 (PHB2), a pivotal factor during mitophagy, thereby upregulating PHB2 protein expression. Knockdown of PHB2 effectively reversed the antisenescence effects of THBru in D-gal-treated cardiomyocytes. On the contrary, overexpression of PHB2 promoted mitophagy and retarded cardiomyocyte senescence, as THBru did. In conclusion, this study identifies THBru as a potent antiaging medicine that induces PHB2-mediated mitophagy and suggests its clinical application prospects.

Abstract
The well known nonlinear fluctuating hydrodynamics theory has grouped diffusions in anharmonic chains into two universality classes: one is the Kardar-Parisi-Zhang (KPZ) class for chains with either asymmetric potential or nonzero static pressure and the other is the Gaussian class for chains with symmetric potential at zero static pressure, such as Fermi-Pasta-Ulam-Tsingou (FPUT)-β chains. However, little is known of the nonequilibrium transient diffusion in anharmonic chains. Here, we reveal that the KPZ class is the only universality class for nonequilibrium transient diffusion, manifested as the KPZ scaling of the side peaks of momentum correlation (corresponding to the sound modes correlation), which was completely unexpected in equilibrium FPUT-β chains. The underlying mechanism is that the nonequilibrium soliton dynamics cause nonzero transient pressure so that the sound modes satisfy approximately the noisy Burgers equation, in which the collisions of solitons was proved to yield the KPZ dynamic exponent of the soliton dispersion. Therefore, the unexpected KPZ universality class is obtained in the nonequilibrium transient diffusion in FPUT-β chains and the corresponding carriers of nonequilibrium transient diffusion are attributed to solitons.

Abstract
Liquid biopsy has the advantage of diagnosing diseases in a non-invasive manner. Seminal plasma contains secretions from the bilateral testes, epididymides, seminal vesicles, bulbourethral glands, and the prostate. These organs are relatively small and contain delicate tubes that are prone to damage by invasive diagnosis. Cell-free seminal nucleic acids test is a newly emerged item in liquid biopsy. Here, we present a comprehensive overview of all known cell-free DNA and cell-free RNAs (mRNA, miRNA, lncRNA, circRNA, piRNA, YRNA, tsRNA, etc.) and discuss their roles as biomarker candidates in liquid biopsy. With great advantages, including high stability, sensitivity, representability, and non-invasiveness, cell-free DNA/RNAs may be developed as promising biomarkers for the screening, diagnosis, prognosis, and follow-up of diseases in semen-secreting organs. Moreover, RNAs in semen may participate in important processes, including sperm maturation, early embryo development, and transgenerational disease inheritance, which may be developed as potential treatment targets for future clinical use.

Abstract
BACKGROUND Motile ciliary disorder (MCD) has been implicated in chronic inflammatory airway diseases such as asthma and COPD. RESEARCH QUESTION What are the characteristics of MCD of the nasal epithelium and its association with disease severity and inflammatory endotypes in adults with bronchiectasis? STUDY DESIGNS AND METHODS In this observational study, we recruited 167 patients with bronchiectasis and 39 healthy control participants who underwent brushing of the nasal epithelium. A subgroup of patients underwent bronchoscopy for bronchial epithelium sampling (n = 13), elective surgery for bronchial epithelium biopsy (n = 18), and blood sampling for next-generation sequencing (n = 37). We characterized systemic and airway inflammatory endotypes in bronchiectasis. We conducted immunofluorescence assays to profile ultrastructural (dynein axonemal heavy chain 5 [DNAH5], dynein intermediate chain 1 [DNAI1], radial spoke head protein 9 [RSPH9]) and ciliogenesis marker expression (ezrin). RESULTS MCD was present in 89.8% of patients with bronchiectasis, 67.6% showed secondary MCD, and 16.2% showed primary plus secondary MCD. Compared with healthy control participants, patients with bronchiectasis yielded abnormal staining patterns of DNAH5, DNAI1, and RSPH9 (but not ezrin) that were more prominent in moderate to severe bronchiectasis. MCD pattern scores largely were consistent between upper and lower airways and between large-to-medium and small airways in bronchiectasis. Coexisting nasal diseases and asthma did not confound nasal ciliary ultrastructural marker expression significantly. The propensity of MCD was unaffected by the airway or systemic inflammatory endotypes. MCD, particularly an ultrastructural abnormality, was notable in patients with mild bronchiectasis who showed blood or sputum eosinophilia. INTERPRETATION Nasal ciliary markers profiling provides complimentary information to clinical endotyping of bronchiectasis.

Abstract
Objective: To systematically evaluate the efficacy and safety of different doses of antiviral drugs in the treatment of herpes zoster. Methods: PubMed, EMBASE, Cochrane Library, VIP, CNKI and WanFang database up to April 9, 2022 were searched. Two reviewers selected the studies according to inclusion and exclusion criteria, and the Cochrane bias risk assessment tool was used for quality evaluation. Data were analyzed by Revman 5.4 software for meta-analysis. The qualitative data used relative risk (RR) as the effect index, and the quantitative data used mean difference (MD) as the effect index. The point estimates and 95%CI of each effect were given. Results: Fourteen randomized controlled trials with 1 831 patients were included in the study. Compared with the 200 mg acyclovir with five times a day, the 800 mg can improve the effective rate, shorten the blister stopping time (MD=-1.29, 95%CI:-1.62- -0.96, P<0.001), relieve the pain faster (MD=-2.73, 95%CI:-4.37- -1.09, P=0.001), shorten the scabbing time (MD=-2.42, 95%CI:-2.96- -1.89, P<0.001) without increasing the adverse reaction rate (RR=1.64, 95%CI:0.80-3.36, P=0.17); Compared with the 300 mg valaciclovir with twice daily, the 900-1 000 mg valaciclovir with three times a day can improve the effective rate(RR=1.17, 95%CI:1.04-1.32, P=0.007), shorten the blister stopping time (MD=-1.53, 95%CI:-2.54- -0.51, P=0.003), relieve the pain faster (MD=-1.04, 95%CI:-1.30- -0.77, P<0.001), shorten the scabbing time (MD=-1.78, 95%CI:-2.80- -0.76, P<0.001), reduce the incidence of postherpetic neuralgia(RR=0.28, 95%CI:0.15-0.52, P<0.001) without increasing the adverse reaction rate (RR=1.47, 95%CI:0.93-2.32, P=0.10); In immunocompromised patients, compared with 1 000 mg valaciclovir with three times a day, 2 000 mg cannot significantly improve the treatment efficacy. There was no significant difference among the efficacy of 250 mg, 500 mg and 750 mg famciclovir, three times a day, in the treatment of herpes zoster. Conclusion: The 800 mg acyclovir with five times a day; 900-1 000 mg valaciclovir and 250 mg famciclovir with three times a day, are better choices in the treatment of herpes zoster.

Abstract
Objective: To analyze the clinical features and risk factors of herpes zoster and the risk factors of postherpetic neuralgia (PHN). Methods: A total of 2 840 patients diagnosed with herpes zoster in Peking University People's Hospital from January 2021 to April 2022 were included. The patients with herpes zoster were aged (59±16), and of which 1 314 (46.3%) patients were male. The patients were divided into PHN group and non-PHN group according to whether the patients with herpes zoster developed PHN. And there were 442 (15.6%) patients developed PHN aged (68±12), and of which 189 (42.8%) were male. The information and medical history of PHN group and non-PHN group were collected. The information of the use of glucocorticoids, immunosuppressive agents, biological agents and targeted medicine within 2 months before herpes zoster occurred, history of surgery within 6 months before herpes zoster occurred, and the duration of PHN were collected. Logistic regression analysis was used to analyze the risk factors of PHN. Results: Out of 2 840 patients, 2 056 (72.4%) with herpes zoster aged 50 years and above. Intercostal nerves was mostly involved in patients with herpes zoster, with a total of 1 532(53.9%). Hypertension (465 cases, 16.4%) accounted for the highest number of patients with chronic diseases, followed by diabetes (337 cases, 11.9%) and coronary heart disease (283 cases, 10.0%). Rheumatoid arthritis (41 cases, 1.4%) accounted for the highest number of patients with connective tissue diseases, followed by Sjogren's syndrome (31 cases, 1.1%), systemic lupus erythematosus (28 cases, 1.0%). Logistic regression analysis showed that age≥50 years old (OR: 4.581; 95%CI: 3.131-6.705),lesion on the upper limb and shoulder (OR: 1.858; 95%CI: 1.129-3.059), hypertension (OR: 1.963; 95%CI: 1.513-2.546) and immunosuppressive treatments (OR: 2.170; 95%CI: 1.254-3.753) were independent risk factors for PHN (all P<0.05). Conclusions: Herpes zoster mostly occurs in people aged 50 and above, and mainly affected intercostal nerves. The most common complications are hypertension and rheumatoid arthritis. Age≥50, lesion on upper limbs and shoulders, hypertension, and immunosuppressive treatments may be independent risk factors of PHN.

Abstract
Objective: To explore the pathological characteristics of three mice models of temporomandibular joint degenerative joint disease (TMJDJD), including osteoarthritis and osteoarthrosis, and to provide references for animal experimental study regarding the pathological mechanism of osteoarthritis and osteoarthrosis. Methods: A total of 54 8-week-old male C57BL/6 mice were selected to construct three TMJDJD animal models, including bilateral temporomandibular joint (TMJ) Freund's complete adjuvant (FCA) injection model, bilateral TMJ monosodium iodoacetate (MIA) injection model, and right TMJ discectomy model. FCA injection model (15 mice) was divided into saline injection group, FCA injection group-1 week, FCA injection group-2 week, FCA injection group-4 week and FCA injection group-6 week, 3 mice were used at each time point, with a total of 6 TMJs on both sides. MIA injection model (15 mice) was separated into saline injection group, MIA injection group-1 week, MIA injection group-2 week, MIA injection group-4 week and MIA injection group-6 week, 3 mice were used at each time point, with a total of 6 TMJs on both sides. TMJ discectomy model (24 mice) was split into control group, discectomy group-2 week group, discectomy group-4 week and discectomy group-6 week, six mice were used at each time point, with a total of six right TMJs. General pictures of the bilateral joints area of mice were collected 1 day after drug injection, and stereoscopic images of condylar tissues were collected 4 weeks after microsurgery for discectomy. Mouse TMJ tissue sections from each time point were stained with HE and toluidine blue, respectively, synovial tissues were scored for synovial inflammation, and the percentage of proteoglycan in condylar cartilage was quantitatively analyzed. Results: One day after intra-articular FCA or MIA injection, the width of bilateral TMJ were significantly increased in FCA injection groups [(24.60±0.46) mm] compared with the saline injection group [(21.63±0.52) mm] (t=4.25, P<0.013), the width of bilateral TMJ in MIA injection groups [(24.50±0.62) mm] were also significantly higher than that in saline injection group [(21.40±0.52) mm] (t=3.82, P=0.019). The synovitis scores in FCA injection groups 1, 2, 4, 6 weeks after FCA injection were significantly higher than that of the saline injection group (F=18.09, P<0.001), with the proteoglycan of condylar cartilage increased firstly and then decreased compared with the saline injection group (F=21.59, P<0.001). Condylar cartilage proteoglycan loss in different degrees were observed 1, 2, 4 and 6 weeks after MIA injection (F=13.59, P<0.001), and synovitis scores were increased at different degrees compared with saline injection group (F=14.79, P<0.001). The morphology of condylar cartilage in discectomy groups mice were severely damaged, synovial tissues showed dense connective tissue lesions at 2, 4 and 6 weeks postoperatively, condylar cartilage tissues showed a time-dependent loss of proteoglycan compared with the control group (F=40.62, P<0.001). Conclusions: Intra-articular FCA injection establishes a mouse model of TMJ osteoarthritis with severe synovial inflammation. Intra-articular MIA injection constructs a mouse model of typical TMJ osteoarthritis. Discectomy establishes a mouse TMJ osteoarthrosis model with severe condylar cartilage destruction.

Abstract
Punica granatum L. (Punicaceae) is a popular fruit all over the world. Owning to its enriched polyphenols, P. granatum has been widely used in treating inflammation-related diseases, such as cardiovascular diseases and cancer. Twenty polyphenols, containing nine unreported ones, named punicagranins A–I (1–9), along with eleven known isolates (10–20), were obtained from the peels. Their detailed structures were elucidated based on UV, IR, NMR, MS, optical rotation, ECD analyses and chemical evidence. The potential anti-inflammatory activities of all polyphenols were examined on a lipopolysaccharide (LPS)-induced inflammatory macrophages model, which indicated that enhancing nitric oxide (NO) production in response to inflammation stimulated in RAW 264.7 cells was controlled by compounds 1, 3, 5–8, 10, 11, 14 and 16–20 in a concentration-dependent manner. The investigation of structure–activity relationships for tannins 6–8 and 12–20 suggested that HHDP, flavogallonyl and/or gallagyl were key groups for NO production inhibitory activity. Western blotting indicated that compounds 6–8 could down-regulate the phosphorylation levels of proteins p38 MAPK, IKKα/β, IκBα and NF-κB p65 as well as inhibit the levels of inflammation-related cytokines and mediators, such as IL-6, TNF-α, iNOS and COX-2, at the concentration of 30 μM. In conclusion, polyphenols are proposed to be the potential anti-inflammatory active ingredients in P. granatum peels, and their molecular mechanism is likely related to the regulation of the p38 MAPK and NF-κB signaling pathways.

Abstract
Hydrocotyle pseudoconferta was an important medicinal plant. The complete plastid genome of this species was reported for the first time. The full length of the complete chloroplast genome is 153,302 bp, with a typical quadripartite organization: a large single-copy (LSC) region of 84,417 bp, a small single-copy (SSC) region of 18,767 bp, and a pair inverted repeat regions (IRa and IRb) with 25,059 bp for each. The complete chloroplast genome of H. pseudoconferta encoded 133 genes, comprising 86 protein-coding genes, 37 tRNA genes, 8 rRNA genes, and 2 pseudogenes. The phylogenetic analysis suggested the closest relationship between H. pseudoconferta and Hydrocotyle nepalensis.

Abstract
Asthma is a chronic inflammatory disease that involves complex gene-environment interactions. Methylation of nucleotides, such as 5-methylcytosine (5mC) in DNA and N6-methyladenosine (m6A) in mRNA, carries important information for gene regulation. Our study screened m6A genes and genes associated with asthma from the Gene Expression Omnibus (GEO) databases GSE63383, GSE119580, GSE38003, GSE34313, GSE13168, and GSE35643. GSE52778, GSE35643, GSE40996, and GSE64744), and DNA methylation data from GSE85568 and GSE146377. We screened out 6 m6A related genes (FTO, IGF2BP2, RBM15, RBMX, WTAP, and YTHDC1) that were significantly dysregulated in asthma or proinflammatory conditions. A correlation study showed a high correlation between m6A genes and gene pairs such as WTAP, IL7R, and TLR2; RBMX, SLC22A4, IL33, TNC, FLG, and IL6R (|r| ≥ 0.8). Following DNA methylation dataset analysis, we proposed several DNA methylation-m6A modification asthma-related gene axes such as cg19032951/cg15153914-IGF2BP2-SMAD3. Interestingly, several target genes, such as SMAD3, possess the ability to participate in DNA methylation processes, which may reciprocally regulate the expression of m6A genes and form a closed-loop regulation axis. Some classic DNA methylation-related genes, such as TET1, UHRF1, and ZBTB4, were also involved. We identified an integrated profile of m6A gene expression in asthma and proposed a novel potential interplay between DNA methylation and m6A modification in asthma pathogenesis. Using the CMAP database, we found that resveratrol may target these dysregulated m6A genes, and therefore may serve as a potential therapeutic agent for asthma.

Abstract
Objective: To explore the changes of cerebral blood perfusion in patients with unilateral sudden sensorineural hearing loss (SSNHL) by using the three-dimensional pseudo-continuous arterial spin labeling (3D pCASL) technique. Methods: The clinical characteristics and ASL data of the 32 patients with unilateral SSNHL were retrospectively collected from November 2020 to June 2021 in Beijing Fuxing Hospital of Capital Medical University, among them, there were 7 males and 25 females, aged from 17 to 73 (44.9±14.4) years. According to the location of SSNHL, they were divided into the left SSNHL (L-SSNHL) group (18 cases) and the right SSNHL (R-SSNHL) group (14 cases). A total of 34 healthy volunteers, which including 14 males and 20 females, aged from 24 to 68 (46.2±14.4) years were enrolled from the local community. The parameter of cerebral blood flow (CBF) of each brain area was obtained using the CereFlow software. The Brainnetome Atlas software package based on MATLAB was used for visualization. The independent-samples t test was conducted to compare the difference of cerebral blood perfusion between the unilateral SSNHL group and healthy control (HC) group. Pearson correlation analysis was used to evaluate the correlation between changes in cerebral blood perfusion and clinical scale scores. Results: The CBF of left orbital gyrus part 5, left inferior temporal gyrus part 7, right orbital gyrus part 5, right inferior temporal gyrus part 1, right inferior temporal gyrus part 7, and right parahippocampal gyrus part 3 of the L-SSNHL group were higher than that in the HC group[(49.1±8.8) vs (31.6±10.9)ml·100g-1·min-1;(42.8±14.3) vs (27.1±13.6)ml·100g-1·min-1;(51.8±9.4) vs (27.2±11.2)ml·100g-1·min-1;(38.8±5.7) vs (28.0±9.2)ml·100g-1·min-1;(38.4±13.8) vs (23.6±10.3)ml·100g-1·min-1;(42.4±9.4) vs (30.1±12.6)ml·100g-1·min-1; all P<0.05]. The CBF of left superior frontal gyrus part 7 and left middle frontal gyrus part 3 of the L-SSNHL group were lower than that in the HC group[(48.2±7.9) vs (59.3±13.7)ml·100g-1·min-1;(46.4±10.3) vs (59.3±16.9)ml·100g-1·min-1;all P<0.05]. The CBF of left orbital gyrus part 5, right orbital gyrus part 5, right inferior temporal gyrus part 1, and right inferior temporal gyrus part 7 of the R-SSNHL group were higher than that in the HC group[(50.6±7.0) vs (31.6±10.9)ml·100g-1·min-1;(50.9±8.8) vs (27.2±11.2)ml·100 g-1·min-1;(38.0±7.2) vs (28.0±9.2)ml·100g-1·min-1;(35.7±8.5) vs (23.6±10.3)ml·100g-1·min-1;all P<0.05]; the CBF of right insular part 4 was lower than that in the HC group [(44.2±6.1) vs (54.4±11.3) ml·100 g-1·min-1, P=0.018]. In the L-SSNHL group, the CBF of left superior frontal gyrus part 7 and right orbital gyrus part 5 were negatively correlated with the VAS score(r=-0.83, -0.81, all P<0.05), and the CBF of right orbital gyrus part 5 was negatively correlated with the THI score(r=-0.75, P=0.013). There was no statistically significant correlation between the remaining differences in brain regions and clinical scale scores(all P>0.05). Conclusion: Changes in cerebral blood perfusion in multiple brain regions were found in patients with unilateral SSNHL by using the 3D pCASL technique.

Abstract
Background A One Health approach has been increasingly mainstreamed by the international community, as it provides for holistic thinking in recognizing the close links and inter-dependence of the health of humans, animals and the environment. However, the dearth of real-world evidence has hampered application of a One Health approach in shaping policies and practice. This study proposes the development of a potential evaluation tool for One Health performance, in order to contribute to the scientific measurement of One Health approach and the identification of gaps where One Health capacity building is most urgently needed. Methods We describe five steps towards a global One Health index (GOHI), including (i) framework formulation; (ii) indicator selection; (iii) database building; (iv) weight determination; and (v) GOHI scores calculation. A cell-like framework for GOHI is proposed, which comprises an external drivers index (EDI), an intrinsic drivers index (IDI) and a core drivers index (CDI). We construct the indicator scheme for GOHI based on this framework after multiple rounds of panel discussions with our expert advisory committee. A fuzzy analytical hierarchy process is adopted to determine the weights for each of the indicators. Results The weighted indicator scheme of GOHI comprises three first-level indicators, 13 second-level indicators, and 57 third-level indicators. According to the pilot analysis based on the data from more than 200 countries/territories the GOHI scores overall are far from ideal (the highest score of 65.0 out of a maximum score of 100), and we found considerable variations among different countries/territories (31.8–65.0). The results from the pilot analysis are consistent with the results from a literature review, which suggests that a GOHI as a potential tool for the assessment of One Health performance might be feasible. Conclusions GOHI—subject to rigorous validation—would represent the world’s first evaluation tool that constructs the conceptual framework from a holistic perspective of One Health. Future application of GOHI might promote a common understanding of a strong One Health approach and provide reference for promoting effective measures to strengthen One Health capacity building. With further adaptations under various scenarios, GOHI, along with its technical protocols and databases, will be updated regularly to address current technical limitations, and capture new knowledge.

Abstract
Objective: The aim of this study was to summarize the clinical and imaging characteristics of post-primary tuberculosis in children, so as to improve the early identification and diagnosis of post-primary tuberculosis. Methods: This was a retrospective study which enrolled children who were admitted to the Department No.2 of Respiratory Medicine, Beijing Children's Hospital Affiliated to Capital Medical University between January 2015 to December 2020 and with a diagnosis of post-primary tuberculosis. Results: A total of 30 patients were enrolled, including 10 males and 20 females. The age on admission were 13.0 (12.0, 13.3) years. Their common symptoms were cough and fever, there were 26 cases (87%) with cough and 23 cases (77%) with fever, but only 4 cases (13%) had other toxic symptoms (night sweat, weakness or weight loss) of tuberculosis other than fever. Blood examination showed that the white blood cell count was (10±3)×109/L, accompanied by elevated proportion of neutrophils (0.69±0.11) and increased level of C-reactive protein (31 (15,81) mg/L). The common radiographic findings of CT were nodular or mass shadow with cavitation (19 cases (63%)), consolidation (13 cases (43%)), bronchogenic spread (12 cases (40%)), hilar or mediastinal lymphadenopathy (5 cases (17%)) in this cohort. The affected locations included the right upper lobe (21 cases (70%)), the left lower lobe (17 cases (57%)) and the right lower lobe (15 cases (50%)). Acid-fast bacillus smears and mycobacterial cultures were attempted for all cases, resulting in 33% (10/30) with smear positivity and 50% (15/30) with culture positivity. Conclusions: Post-primary tuberculosis in children has no specific clinical manifestations. Imaging of chest CT is mainly manifested as nodular shadow with cavitation, consolidation or bronchogenic spread. Accurate identification of post-primary tuberculosis is crucial for preventing the spread and early treatment of tuberculosis.

Abstract
As one of raw materials, the rhizome of Imperata cylindrica var. major (Nees) C.E. Hubb. is used in kinds of preparations curing inflammation related diseases, while its effective substances are not yet clear. In this paper, its chemical constituents and their anti-inflammatory activities were investigated. As results, ten compounds, named as imperphenoside A (1), imperphenols B (2) and C (3), imperphenosides D-F (4-6), and imperlignanosides A-D (7-10), along with previously reported thirty-seven known ones (11-47) were obtained from it. Their structures were ascertained basing on the extensive spectroscopic methods and electronic circular dichroism data analysis. Meanwhile, compounds 4, 11, 12, 24, 27, 31, 32, 37, 43, 45, and 47 exhibited nitric oxide inhibitory effects in concentration dependent at 3, 10, and 30 μM on lipopolysaccharides induced RAW 264.7 cells. Moreover, the western blot analysis indicated that compounds 4, 11, 43, and 47 could restrain the phosphorylation of nuclear factor kappa-B kinase to down-regulate the protein expression of inflammatory cytokines such as inducible nitric oxide synthase, interleukin-6 and tumor necrosis factor-α. In conclusion, they might play the anti-inflammatory effects through regulating NF-κB signaling pathway.

Abstract
Through literature research and standard retrieval, Corydalis-derived medicinal materials, the origins, and related standards were summarized. Finally, 27 medicinal materials were screened out, involving 71 species(varieties). Among them, only 11 are recorded in Chinese Pharmacopoeia(2020), National Standard for Chinese Patent Drugs·Tibetan Medicine, Tibetan Medicine Standards, and other local standards, including Corydalis Bungeanae Herba and Corydalis Herba. The names and original plants of the medicinal materials are different in different standards, and the phenomena of "same medicinal material with different names" and "same name for different medicinal materials" are prominent. Most standards only include the traits, microscopic identification, and physico-chemical property identification, with unsound quality criteria. Thus, efforts should be made to strengthen the sorting of Corydalis medicinal plants, herbal textual research, and investigation of the resources and utilization. Moreover, via modern techniques, the chemical components and medicinal material basis of different original plants should be explored and sound quality standards should be established to improve the safety and quality of Corydalis-derived medicinal materials. Summarizing Corydalis medicinal plants, Corydalis-derived medicinal materials, and related standards, this study is expected to provide a reference for the standard formulation, quality evaluation, expansion of drug sources, and rational development and utilization of Corydalis resources.

Abstract
Aim: Whether accelerated aging, reflected by sirtuin 1 (SIRT1) expression, is implicated in bronchiectasis remains largely unknown. We sought to determine the patterns of SIRT1 and other aging markers in systemic circulation and airways and their expression levels associated with bronchiectasis severity and exacerbation. Methods: We enrolled 132 patients with bronchiectasis and 50 healthy subjects in a prospective cohort study to profile aging markers in systemic circulation and recruited 36 patients with bronchiectasis and 32 disease controls (idiopathic pulmonary fibrosis or tumors) in a cross-sectional study to profile aging markers in bronchial epithelium of both large-to-medium and small airways. We profiled aging marker expression from peripheral blood mononuclear cells and enumerated the positively stained cells for detection of aging marker expression in bronchial epithelium. Results: Compared with healthy controls, the relative telomere length (median: 0.88 vs. 0.99, p = 0.009), SIRT1 (median: 0.89 vs. 0.99, p = 0.002), and Ku80 (median: 0.87 vs. 0.96, p < 0.001) expression levels were consistently lower in the peripheral blood mononuclear cells among patients with bronchiectasis and modestly discriminated patients with bronchiectasis from healthy controls. No remarkable changes in SIRT1, telomere length, or Ku70 were identified at onset of exacerbation. Within the bronchial epithelium, the percentage of positively stained cells was lower for SIRT1 (median: 25.1 vs. 57.2%, p < 0.05) and numerically lower for p16 (median: 40.0 vs. 45.1%) and p21 (median: 28.9 vs. 35.9%) in patients with bronchiectasis than in disease controls (p > 0.05). Conclusion: SIRT1 was downregulated in systemic circulation and bronchiectatic airways, which was independent of disease severity and lung function impairment.

Abstract
Objective: To investigate a preoperative multi-sequence MRI-based radiomic nomogram for prediction of platinum-based chemotherapy sensitivity in patients with epithelial ovarian cancer (EOC). Methods: The complete data of 114 patients with EOC confirmed by surgery and pathology in Nantong Tumor Hospital of Nantong University from January 2015 to May 2020 were retrospectively analyzed, with an average age of 32-76 (57±8) years. All patients underwent platinum-based chemotherapy after maximal cytoreductive surgery. According to whether relapse occurred within 6 months, those patients were divided into platinum-resistant disease (PR, n=39) group and platinum-sensitive disease group (PS, n=75).All patients underwent MRI examination before treatment, and the 3-dimensional solid component of the tumor area of interest (ROI) on T2-weighted image (T2WI), diffusion weighted imaging (DWI) and T1-weighted image-enhanced image (T1CE) were manually delineated using Itk-snap software.Then AK software was imported for radiomics features extracting. They were randomly divided into training group (n=80) and validation group (n=34) in a ratio of 7∶3 (stratified sampling method). Firstly, the radiomics features were initially screened by the method of maximum correlation and minimum redundancy (mRMR), and features with the greatest predictive power were retained. Then, the LASSO regression analysis was performed to select the best features and construct the radiomics model. Univariate analysis was used to screen out clinical relevant factors, which combined with radiomic score (Radscore) was applied to develop a radiomics nomogram by multivariable logistic regression. Receiver operating characteristic (ROC) curve and decision curve analysis (DCA) were used to evaluate the predictive ability and clinical application value of radiomics model, clinical related factor model and radiomics nomogram. Results: Compared with the radiomics model (12 optimal radiomics features) and the clinical relevant factors model (residual disease, neutrophil count, carbohydrate antigen 199), the radiomics nomogram model demonstrated the best prediction performance: in the training groups, the AUC (Area Under the ROC Curve), accuracy, sensitivity, and specificity were 0.90 (95%CI:0.82-0.99), 90.0%, 89.0%, and 92.0%, respectively. In the validation groups, the AUC, accuracy, sensitivity, and specificity were 0.89 (95%CI:0.78-1.00), 85.0%, 87.0%, and 80.0%, respectively. DCA shows that the use of nomograms with a threshold in the range of 0.01 to 0.90 has a greater clinical application value in predicting the sensitivity of platinum chemotherapy in patients with EOC. Conclusion: The multi-sequence MRI-based radiomics nomogram has a high diagnostic value in predicting the sensitivity of platinum-based chemotherapy in patients with EOC.

Objective: To screen the physical, psychological and behavioral factors related to patients with temporomandibular disorders (TMD) by using Axis Ⅱ assessment instruments of diagnostic criteria for TMD(DC/TMD). And to provide a reference to establish personalized diagnosis and treatment plans for TMD patients so as to prevent TMD and reduce predisposing factors. Methods: A total of 141 TMD patients, who were admitted in the Department of Oral and Maxillofacial Surgery in School and Hospital of Stomatology, Wuhan University from October 2018 to February 2021 were selected. There were 121 females and 20 males, with an average age of 30 years. A total of 90 healthy people were included as controls. A full-time psychologist conducted relevant questionnaire surveys. The questionnaires include general clinical survey forms and TMD symptom questionnaire. In addition, Axis Ⅱ assessment instruments include graded chronic pain scale, jaw functional limitation scale, oral behaviors checklist, patient health questionnaire-9 (depression), generalized anxiety disorder scale, patient health questionnaire-15 (physical symptoms), etc. The main observational indicators include: pain level, pain impact rates, overall classification of chronic pain, limited chewing function score, limited motor function score, limited communication function score, total jaw function restricted score, depression score, anxiety score, somatic symptom score and oral behavior score.The survey data were imported into SPSS 22.0 software for statistical analysis. Results: In the TMD group 60.3% (85/141) patients had various degrees of pain, 24.1% (34/141) of those with pain effect grades from 1 to 3 and 61.0% (86/141) showed chronic pain overall grades from Ⅰ to Ⅳ. The chewing function restricted score was 2.67(1.17, 4.25), motor function restricted score was 4.25(1.75, 6.12), communication function restricted score was 1.13(1.00, 2.25) and total jaw function restricted score was 2.56(1.47, 4.15) respectively. Patients with mild depression or above accounted for 59.6%(84/141), patients with mild anxiety or above accounted for 56.7%(80/141), 46.1%(65/141) patients had somatization symptoms. Statistical differences (P<0.05) were determined between TMD group and control group in various scores of jaw function, oral behavior grading, depression, anxiety, and physical symptoms. Physical symptoms had significantly statistical difference between different diagnostic classification(P<0.05). Meanwhile, among the different chronic pain levels in the TMD group, there were statistical differences in the various scales of mandibular dysfunction, depression, anxiety, and somatization. In the TMD group, other significant differences were noticed between males and females in terms of the average score of mouth opening, verbal and facial communication, the total score of mandibular dysfunction as well as physical symptoms (P<0.05). Conclusions: Compared with the healthy people, patients with TMD had more abnormal oral behaviors, different restriction of the mandibular functional activities. At the same time, depression, anxiety, and somatization were more serious. Patients with osteoarthritis and subluxation of temporomandibular joint were more likely to suffer physical symptoms. TMD patients suffering from pain had more severe mandibular dysfunction and symptoms of depression, anxiety, and somatization.

Abstract
In this work, we reported the preparation of the hollow zeolitic imidazolate framework-7 (ZIF-7) via etching ZIF-7 with tannic acid, and further fabricated the hollow ZIF-7 coated fiber for the solid phase microextraction (SPME) of the five volatile biomarkers (acetone, isopropanol, hexanal, hexanol and decanal) generated from breast cancer cell lines. The hollow structure not only endowed higher extraction performance for the SPME of analytes, but also improved the diffusion rate of the analytes inside the hollow ZIF-7. Under the optimal conditions, the hollow ZIF-7 coated fiber offered high extraction capacity (25-153 mg g-1) and enhancement factors (EFs, 2023-11250) for the five biomarkers, good linearity (R2 > 0.9918) of acetone and isopropanol (2.5-500 μg L-1) and hexanol, hexanal, and decanal (1.0-100 μg L-1), low limits of detection (S/N = 3) of 0.07-0.53 μg L-1 and the limit of quantifications (LOQs, S/N = 10) of 0.23-1.76 μg L-1. The precisions (RSDs, %) for intra-day (n = 6), inter-day (n = 5) and fiber-to-fiber (n = 6) were 2.8-7.5%, 4.3-8.5%, and 4.2-14.6%, respectively. The high EFs of the hollow ZIF-7 coated fiber for the five biomarkers resulted from the integrated effects of the large surface area, the unique porous structure, hydrophobic interaction, gate-opening effect, and enhanced properties after etching including faster mass transport, multiple active components, and more exposed active sites. The fabricated hollow ZIF-7 coated fiber lasted at least 140 cycles of extraction/desorption/aging without obvious decrease of extraction ability and no change of crystal structure. Finally, the hollow ZIF-7 coated fiber combined with GC-FID had been successfully used to detect the five biomarkers in the headspace gas of human breast cancer cell lines (MDA-MB-231) and normal mammary cell lines (CCD-1095Sk) with the recoveries of 84-105%. These results revealed the prospect of hollow MOFs as efficient adsorbents for sample pretreatment.

Abstract
Objective: To explore the early clinical clues for diagnosis of chronic granulomatous disease (CGD). Methods: One hundred and thirty-nine children with CGD seen in Beijing Children's Hospital from January 2007 to October 2020 were included in this study. The clinical features including age of onset, first presentations, reason for being hospitalized, etiology, imaging features, clues for early diagnosis of all patients were evaluated retrospectively. According to the time of diagnosis, the patients were divided into two groups, cases diagnosed before 2015 and after 2015 and 2015. The time of diagnosis, the length of stay and the hospital charges were compared between the two groups. T test and χ2 test were used for statistical analyses. Results: One hundred and nineteen of the cases were males and 20 were females. The age of onset was 4 months (8 d to 14 years), and 103 cases (74.1%) had onset before 1 year of age. The age at diagnosis was 1.8 years (21 d to 14.7 years), and the time of diagnosis delay was 1 year (7 d to 13.7 years). One hundred and thirty-five cases (97.1%) had pulmonary infection as the main reason for hospitalization, of whom 76 cases (56.3%) had positive pulmonary etiology. One hundred and thirty-six patients (97.8%) were referred cases, of whom 5 were suspected of CGD before referral, and the misdiagnosis rate was as high as 96.3% (131/136). Eight early clues for diagnosis were found, the frequency from high to low, large bacillus Callmette-Guer scar in 99 cases (70.5%), left axillary lymphadenopathy or calcification in 73 cases (52.5%), skin or other lymph node infections in 58 cases (41.7%), skin scars in 50 cases (36.0%), multiple lung nodules in 42 cases (30.2%), perianal abscess in 35 cases (25.2%), pulmonary Aspergillus infection in 26 cases (18.7%) and pulmonary Burkholderia infection in 15 cases (10.8%). A total of 120 cases of CGD were diagnosed by respiratory burst test during hospitalization, including 55 cases diagnosed before 2015 and 65 cases diagnosed after 2015. After using these 8 early diagnosis clues, the cases diagnosed after 2015 had shorter time of diagnosis and the length of stay and lower hospitalization charge than cases diagnosed before 2014, and the difference was statistically significant ((25±7) vs. (10±5) d, (29±7) vs. (18±6) d, (3.7×104±1.2×104) vs. (3.2×104±1.2×104) Yuan, t=13.763, 9.262, 2.381, all P<0.05). Conclusions: Patients with CGD are younger at onset and the diagnosis is delayed. Pulmonary infections are the most common. Large BCG scar, left axillary lymphadenopathy or calcification, skin or other lymph node infections, skin scars, multiple lung nodules, perianal abscesses, pulmonary Aspergillus infection and Burkholderia infection can help early diagnosis of CGD.

Abstract
This study evaluated the outcome indicators of the randomized controlled trials(RCTs) of traditional Chinese medicine(TCM) in the treatment of postmenopausal osteoporosis(PMOP) to provide a reference for the related research. Four Chinese databa-ses(CNKI, VIP, Wanfang and CBM) and three English databases(Cochrane Library, EMbase and PubMed) were searched syste-matically to screen RCTs of TCM in the treatment of PMOP according to the pre-set criteria, and the quality of the included trials was evaluated by the Cochrane risk-of-bias tool. A total of 29 627 articles were initially retrieved, and finally, 43 articles were included, including 34 in Chinese and 9 in English. As revealed by the results, the outcome indicators of 43 RCTs were mainly divided into six categories, with biochemical indicators accounting for 54.59%, bone mineral density(BMD) for 26.57%, quality of life for 6.28%, fracture for 1.94%, safety for 5.31%(including adverse reactions or events) and others for 5.31%. Biochemical indicators showed the maximum occurrence, followed by BMD. Many problems were found in the selection of outcome indicators of the TCM RCTs in the treatment of PMOP, such as the confusion of primary and secondary outcome indicators, the lack of endpoint criteria and vital clinical outcome indicators substituted by intermediate indicators, inconsistent evaluation standard of syndrome curative efficacy and neglected blinding in the measurement of subjective outcome indicators. The problems also included importance given to the efficacy indicators instead of the adverse outcome indicators, unnormalized indicator name, large quantitative range of the indicators, unconventional application of TCM efficacy criteria, seldom used confidence interval, relative effect indicator and absolute effect indicator.

Abstract
This study aims to explore the efficacy of Chinese medicine injections( CMIs) for promoting blood circulation and removing blood stasis for acute cerebral infarction from the perspectives of clinical medication and mechanism of action based on two complex network analysis methods. Firstly,the current 13 kinds of CMIs for acute cerebral infarction were obtained from 2019 List of medicines for national basic medical insurance,industrial injury insurance and maternity insurance with the method of network Meta-analysis. Secondly,with the use of network pharmacology,the mechanisms of top 2 CMIs with the highest therapeutic effect for acute cerebral infarction were explored from two levels including core target and network function enrichment. The result of network Meta-analysis showed Mailuoning Injection was superior to Danhong Injection in terms of total effectiveness rate for neurological deficit score and NIHSS score. The network pharmacology results showed that Mailuoning Injection had more core targets,interaction networks,enriched biological functions and more signaling pathways than Danhong Injection for cerebral infarction. Both two CMIs can play a role in treating cerebral infarction through core targets such as TP53 and NOS3,biological processes such as fibrinolysis,nitric oxide biosynthesis,nitric oxide-mediated signal transduction,negative regulation of apoptosis in endothelial cells and apoptosis process,as well as the signaling pathways such as PI3 K-Akt signaling pathway,HIF-1 signaling pathway and cell apoptosis signaling pathways. The results of pharmacological studies explained their differences in clinical efficacy to a certain extent. A research strategy based on curative effect should be advocated in efficacy evaluation of traditional Chinese medicine,where comparative research on clinical efficacy can be conducted firstly,and then mechanism research based on outstanding effective drugs to better provide references and basis for selection of similar competitive drugs for one disease in the clinical practice.

Abstract
Background and Objective: Previous studies have evaluated the efficacy (OS, overall survival; PFS, progression-free survival; ORR, objective response rate) and adverse events of bevacizumab combined with platinum-based chemotherapy in first-line treatment of advanced non-small-cell lung cancer (NSCLC) compared with chemotherapy alone. However, the results were inconsistent. Methods: We conducted a comprehensive search of PubMed, EMBASE, and Cochrane Library for potentially eligible articles. The outcomes were evaluated in terms of risk ratio (RR) or hazard ratio (HR) and the associated 95% confidence intervals (CIs). Meta-analysis was performed using the Stata 12.0 software, and subgroup analyses were performed based on the treatment and bevacizumab dose. Results: Six randomized controlled trials with 2,465 patients were included in this meta-analysis. The results demonstrated that bevacizumab significantly increased OS (HR = 0.87, 95% CI 0.79–0.96), extended PFS (HR = 0.65, 95% CI 0.54–0.77), and increased ORR (ES = 0.40, 95% CI 0.31–0.48) when added to first-line platinum-based chemotherapy in patients with advanced NSCLC. Subgroup analyses showed that only the higher dose (15 mg/kg) of bevacizumab plus carboplatin–paclitaxel significantly extended the OS and PFS, but both 7.5 mg/kg and 15 mg/kg of bevacizumab improved ORR. However, both 7.5 mg/kg and 15 mg/kg of bevacizumab could only increase PFS and ORR, but not extend OS, when added to cisplatin–gemcitabine. Bevacizumab significantly increased the risk of grade ≥3 events of febrile neutropenia, haemorrhagic events, hypertension, leukopenia, neutropenia, and proteinuria. Conclusion: Bevacizumab significantly increases OS, PFS, and ORR when added to first-line platinum-based chemotherapy in patients with advanced NSCLC, with no new safety signals found. Moreover, bevacizumab (15 mg/kg) plus carboplatin–paclitaxel is a better alternative in increasing OS to carboplatin–paclitaxel and bevacizumab (7.5 mg/kg and 15 mg/kg) plus cisplatin–gemcitabine.

Abstract
Objective: To compare the cerebral perfusion differences between the symptomatic patients and the asymptomatic patients with unilateral middle cerebral artery (MCA) severe stenosis or occlusion by using three post labeling delays (PLD) of the three-dimensional pseudo-continuous arterial spin labeling (pCASL) technique. Methods: The clinical characteristics and ASL data of the 27 patients with severe stenosis or occlusion of unilateral MCA (18 symptomatic, 9 asymptomatic) were prospectively enrolled from April 2018 to November 2019 in the Department of Radiology of China-Japan Friendship Hospital. There were 16 males and 11 females, age range from 29 to 85 (55±13) years. According to the symptoms, they were divided into symptomatic group (18 cases) and asymptomatic group (9 cases). The parameters of cerebral blood flow (CBF), mean cerebral blood flow (mCBF), arterial transit time (ATT) and arterial cerebral blood volume (aCBV) were obtained using the Cereflow software. One-way multivariate analysis of variance (one-way MANOVA) was used to compare the differences of cerebral perfusion parameters between symptomatic group and asymptomatic group, and between the affected side and the control side in the two groups. Two-way ANOVA was used to evaluate the effects of symptoms, hemisphere (affected and control side), PLD times (1.5, 2.0 and 2.5 s) and the interaction between the two factors. Results: The CBF of the affected leptomeningeal branch and perforating branch of MCA in symptomatic group was lower than that in asymptomatic group [(36.8±10.2) ml·100 g-1·min-1 versus (46.6±13.9) ml·100 g-1·min-1, F(1, 75)=13.279, P=0.000 49; (32.3±8.3) ml·100 g-1·min-1 versus (36.2±7.5) ml·100 g-1·min-1, F (1, 75)=4.065, P=0.047], and there was no interaction between the symptom and PLD [F(2, 75) =0.061, P=0.940]. In the symptomatic group, the CBF of the leptomeningeal branch and perforating branch of MCA in affected side was lower than that in control side [(36.8±10.2) ml·100 g-1·min-1 versus (43.7±10.0) ml·100 g-1·min-1, F(1, 102)=12.559, P=0.000 59; (32.3±8.3) ml·100 g-1·min-1 versus (36.4±8.0) ml·100 g-1·min-1, F(1, 102)=6.493, P=0.012]. In the symptomatic group, the CBF of leptomeningeal branch of MCA when PLD was 2.5 s was 7.34 ml·100 g-1·min-1, which were higher than that when PLD of 1.5 s (95%CI: 0.72-13.9, P=0.03). There was no interaction between PLD and hemisphere [F(2, 102) =0.307, P=0.736]. Conclusions: The collateral circulation in the blood supply area of MCA in asymptomatic patients with severe unilateral MCA stenosis or occlusion is more abundant than that in symptomatic patients. ASL can be an effective technique for evaluating the cerebral perfusion of collateral circulation in patients with severe stenosis or occlusion of MCA.

Abstract
Indoleamine 2, 3-dioxygenase (IDO) is an important immunoregulatory enzyme, which mediates immune effects by depleting tryptophan and producing multiple metabolites. Recently, the studies on the immune function of IDO have been mostly restricted in tumors and autoimmune diseases. Nevertheless, there are few studies pertaining to the role of IDO in parasitic diseases, notably in parasite-host immune interactions. This review mainly describes IDO-mediated immunoregulatory effects and its regulation of parasite-host interactions, so as to provide insights into the development of immune intervention schemes against parasitic diseases.

Abstract
Cerebral ischemia causes severe neurological disorders and neuronal dysfunction. Baicalin (BC), geniposide (GP), and their combination (BC/GP) have been shown to inhibit post-ischemic inflammatory injury by inhibiting the 5-LOX/CysLTs pathway. The aims of this study were to observe the inhibitory effects of BC/GP on the activation of microglial cells induced by oxygen glucose deprivation and reoxygenation (OGD/R) and to investigate whether the 5-LOX/LTB4 pathway was involved in these effects. Molecular docking showed that BC and GP exhibited considerable binding activity with LTB4 synthase LTA4H. BV-2 microglia were transfected with a 5-LOX overexpression lentiviral vector, and then OGD/R was performed. The effects of different concentrations of BC, GP, and BC/GP (6.25 μM, 12.5 μM, and 25 μM) on cell viability and apoptosis of microglia were evaluated by MTT and flow cytometry. The expression of TNF-α, IL-1β, NF-κB, and pNF-κB also was measured by ELISA, Western blots and immunofluorescence. Western blots and qRT-PCR analysis were used to determine the levels of CD11b, CD206, and 5-LOX pathway proteins. Results showed that BC, GP, and BC/GP reduced the apoptosis caused by OGD/R in a dose-dependent manner, and cell viability was significantly increased at a concentration of 12.5 μM. OGD/R significantly increased the release of TNF-α, IL-1β, NF-κB, pNF-κB, and CD11b. These effects were suppressed by BC, GP, and BC/GP, and the OGD/R-induced transfer of NF-κB p65 from the ctytoplasm to the nucleus was inhibited in microglia. Interestingly, the LTB4 inhibitor, U75302, exhibited the same effect. Also, BC, GP, and BC/GP significantly reduced the expression of 5-LOX pathway proteins. These results demonstrated that BC/GP inhibited OGD/R-induced polarization in BV2 microglia by regulating the 5-LOX/LTB4 signaling pathways and attenuating the inflammatory response. Our results supported the theoretical basis for additional in-depth study of the function of BC/GP and the value of determining its unique target, which might provide a new therapeutic strategy for ischemic cerebrovascular disease.

Abstract
OBJECTIVE The finite element method was used to investigate the biomechanical adjustments of adjacent and fixed segments after lumbar fusion and fixation with traditional trajectory (TT) and cortical bone trajectory (CBT) screws. METHODS The model used was a validated nonlinearly L3-S1 finite element model. Interbody fusion cages and 2 types of screws were used to work on the L4-L5. To simulate flexion, extension, lateral bending, and axial rotation, all models were loaded in 3 planes with a compressive pre-load of 400 N and a bending moment of 7.5 N/m. Under various loading conditions, the range of motion (ROM), peak Von Mises stress of the vertebral body, stress of the intervertebral disc, stress of the facet joints, stress of the endplate, and stress of internal fixation were compared. RESULTS In all instrumentation models, the ROM at fixed segments decreased. At adjacent segments, the ROM of the CBT model was greater than that of the TT model. The CBT model had a greater peak Von Mises stress of the L4 and L5 vertebral bodies, as well as greater stress of internal fixation, than the TT model. Furthermore, as compared with the TT model, the CBT model's facet joint and endplate stress were lower at fixed segments but higher at adjacent segments. The stress on the L3-L4 and L5-S1 intervertebral discs in the CBT and TT models, on the other hand, was nearly equivalent. CONCLUSIONS At the fixed section, CBT may provide slightly better stability, endplate tension, and facet joint stress than TT. The greater ROM, endplate stress, and facet joint stress of CBT in adjacent segments, on the other hand, should be taken into account in the future.

Abstract
OBJECTIVE To investigate the association of vitamin D receptor (VDR) gene polymorphisms with OA susceptibility. METHODS Meta-analyses were performed using allelic contrast, contrast of homozygotes, and recessive and dominant models to clarify the association between OA and VDR ApaI, BsmI, TaqI and FokI polymorphisms. Odds ratio (OR) and the corresponding 95% CI were obtained, and subgroup analyses were performed based on the ethnicity and OA sites. RESULTS A total of 18 studies with 2983 OA patients and 4177 controls were included in this meta-analysis. There were statistically significant associations in the spine between OA susceptibility and the VDR BsmI (B vs b: OR = 1.25, 95% CI: 1.03, 1.53, P = 0.026; BB vs bb: OR = 1.56, 95% CI: 1.02, 2.37, P = 0.038) and TaqI (T vs t: OR = 0.73, 95% CI: 0.54, 0.99, P = 0.044; TT vs Tt + tt: OR = 0.63, 95% CI: 0.42, 0.95, P = 0.028) polymorphisms, but not for the other polymorphisms. A statistically significant association was found between the VDR FokI polymorphism and OA susceptibility in the knee in the recessive model contrast (FF vs Ff + ff: OR = 0.63, 95% CI: 0.42, 0.95, P = 0.028), but this result was only pooled from one study. However, no significant associations were found between the VDR ApaI polymorphism and OA. Besides, ethnic stratification also indicated that there was no significant association between VDR gene polymorphism and OA in Caucasians or Asians. CONCLUSION Our meta-analysis suggests that the VDR BsmI and TaqI polymorphisms are associated with OA susceptibility in the spine. However, the VDR ApaI polymorphism is not a significant genetic risk factor for OA.
