Abstract
OBJECTIVE Parathyroid carcinoma (PC) is a rare disease with high rates of misdiagnosis and recurrence. This report summarized the clinical and pathological characteristics of 10 patients with PC at our hospital, to improve the early recognition and prognosis of PC. METHODS The clinical manifestations, imaging findings, pathological features, treatments, and prognostic data of 10 patients diagnosed with PC at the First Medical Center, Chinese PLA General Hospital from 2003 to 2021 were analyzed. RESULTS There were 7 male and 3 female patients with PC whose average age was 41.4 ± 9.4 years. All patients had bone involvement (bone pain and/or osteoporosis), meanwhile 6 patients had kidney stones and 7 patients had palpable neck masses. Five patients presented with tumor metastasis, invading lymph nodes, lung, liver, or bone. Laboratory examinations revealed elevated serum total calcium (4.15 ± 0.81 mmol/L), parathyroid hormone (PTH, 1236.1 ± 519.9 pg/mL) and alkaline phosphatase (405.8 ± 219.0 IU/L) levels. Especially, hypercalcemic crisis occurred in 9 patients. The diagnosis of PC depended on histopathological features of the parathyroid tumor, including capsular and/or vascular invasion. All patients underwent at least en bloc resection. In the follow-up, six patients with relatively high preoperative PTH levels (1519.5 ± 436.8 pg/mL) relapsed postoperatively. Two patients with the Ki-67 index ≥ 10% in parathyroid tumor tissue and distant metastasis died within 2 years after the operation. CONCLUSION Severe bone pain, kidney stones, hypercalcemic crisis, and markedly elevated PTH usually indicate PC. A markedly elevated PTH level, tumor metastasis, and the Ki-67 index ≥ 10% may be indicators of poor prognosis.

Abstract
ObjectiveThe overexpression of polo-like kinase 1 (PLK-1) has been found in a broad spectrum of human tumors, making it an attractive prognostic tumor biomarker. Nowadays, PLK-1 is considered a cancer therapeutic target with clinical therapeutic value. The aim of the present study was to systematically review the prognostic and therapeutic value of PLK-1 in different malignant neoplasms.MethodsA systematic literature search of the Cochrane Library, PubMed, Web of Science, and China National Knowledge Internet (CNKI) databases was conducted between December 2018 and September 2022. In total, 41 published studies were screened, comprising 5,301 patients. We calculated the pooled odds ratios (ORs) and corresponding 95%CIs for the clinical parameters of patients included in these studies, as well as the pooled hazard ratios (HRs) and corresponding 95% CIs for 5-year overall survival (OS).ResultsOur analysis included 41 eligible studies, representing a total of 5,301 patients. The results showed that overexpression of PLK-1 was significantly associated with poor OS (HR, 1.57; 95% CI, 1.18–2.08) and inferior 5-year disease-free survival/relapse-free survival ((HR, 1.89; 95% CI, 1.47–2.44). The pooled analysis showed that PLK-1 overexpression was significantly associated with lymph node metastasis, histological grade, clinical stages (p < 0.001 respectively), and tumor grade (p < 0.001). In digestive system neoplasms, PLK-1 overexpression was significantly associated with histopathological classification, primary tumor grade, histological grade, and clinical stages (p = 0.002, p = 0.001, p < 0.0001, respectively). In breast cancer, PLK-1 was significantly associated with 5-year overall survival, histological grade, and lymph node metastasis (p < 0.001, p = 0.003, p < 0.001, respectively). In the female reproductive system, PLK-1 was significantly associated with clinical stage (p = 0.011). In the respiratory system, PLK-1 was significantly associated with clinical stage (p = 0.021).ConclusionOur analysis indicates that high PLK-1 expression is associated with aggressiveness and poor prognosis in malignant neoplasms. Therefore, PLK-1 may be a clinically valuable target for cancer treatment.

Abstract
Molecular targeting and immunotherapy provide durable responses for advanced lung cancer clinical therapy in many patients. However, the mechanisms of occurrence of progressive disease and resistance to targeted therapy and immunotherapy have not been elucidated. Herein, we report two cases of small cell transformation of non-small cell lung cancer (NSCLC) after targeted therapy or immunotherapy. The first case was a 63-year-old female patient presenting with cough and expectoration. Left lung invasive adenocarcinoma was diagnosed after left lung tumor biopsy. After epidermal growth factor receptor-tyrosine kinase inhibitor (EGFR-TKI) targeted therapy for almost 2 years, disease progression and symptom aggravation were observed. Pathological and immunohistochemical staining results after biopsy revealed small cell lung cancer (SCLC). The second case was a 75-year-old male patient diagnosed with stage IV squamous cell carcinoma of the lung, who received carboplatin/paclitaxel adjuvant chemotherapy and pembrolizumab treatment with partial response. Disease progression and metastasis occurred within 15 cycles of immunotherapy. Computed tomography revealed a lower left lung tumor. Cytological examination of lung lavage fluid and biopsy under thoracoscope revealed SCLC. In conclusion, histological transformation to SCLC is a potential mechanism of NSCLC resistance to targeted therapy or immunotherapy. During treatment, clinicians should monitor serum tumor markers or genome sequencing, particularly in patients with disease progression, as this may be beneficial for early detection of SCLC transformation. Repeated biopsy can be performed if necessary, and the therapeutic regimen can be adjusted in a timely manner according to the results of molecular pathological tests for personalization and whole-process management.

Abstract
Objective: To evaluate the transmissibility of 2019-nCoV Omicron variant under the current prevention and control strategy in Beijing, and provide evidence for the prevention and control of COVID-19. Methods: The information of 78 Omicron variant infection cases involved in clear transmission chains in Beijing during 7-25 March, 2022 were collected, the incubation period and serial interval of the disease were fitted by using Gamma and Weibull distribution. Markov Chain Monte Carlo approach was used to estimate the time-varying reproduction number (Rt). Results: The median of the incubation period (Q1, Q3) of Omicron variant infection was 4.0 (3.0, 6.0) days, and the serial interval was 3.0 (2.0, 5.0) days. The median of the serial interval (Q1, Q3) was 2.0 (1.0, 4.0) days in unvaccinated cases and 4.0 (2.0, 6.0) days in vaccinated cases (Z=-2.12, P=0.034), and 2.0 (1.5, 3.0) days in children and 4.0 (2.0, 6.0) days in adults, respectively (Z=-2.02,P=0.044), the differences were significant. The mean of Rt was estimated to be 4.98 (95%CI: 2.22-9.04) for Omicron variant in this epidemic. Conclusion: Omicron variant has stronger transmissibility compared with Delta variant. It is necessary to strengthen the routine prevention and control COVID-19, promote the vaccination and pay close attention to susceptible population, such as children.

Abstract
Anaerobic digestion is a prevalent bioenergy production process relying on a complex network of symbiotic interactions, where the nutrient based cross-feeding is an essential microbial mechanism. Here, the cross-feeding function was assessed by analyzing extracellular polymeric substances-associated amino acids in microbial aggregates collected from 14 lab-scale anaerobic digesters, as well as deciphering their genetically biosynthetic potential by syntrophic bacteria and methanogens. The total concentration of essential amino acids ranged from 1.2 mg/g VSS to 174.0 mg/g VSS. The percentages of glutamic acid (8.5 ∼ 37.6%), lysine (2.7 ∼ 22.6%), alanine (5.6 ∼ 13.2%), and valine (3.0 ∼ 10.4%) to the total amount of detected amino acids were the highest in most samples. Through metagenomics analysis, several investigated syntrophs (i.e., Smithella, Syntrophobacter, Syntrophomonas, and Mesotoga) and methanogens (i.e., Methanothrix and Methanosarcina) were auxotrophies, but the genetic ability of syntrophs and methanogens to synthesize some essential amino acids could be complementary, implying potential cross-feeding partnership.

Abstract
PURPOSE To investigate the clinical characteristics, endocrinological function, and etiology of bilateral adrenal lesions in hospitalized patients. METHODS A retrospective study of 777 patients with bilateral adrenal lesions was conducted at the Chinese People's Liberation Army General Hospital between January 2013 and January 2018. Patients' demographic features, hormonal profiles, imaging findings, and histopathological findings were reviewed from database records. RESULTS Of the 777 patients with bilateral adrenal lesions, 495 were men. The mean age at diagnosis was 52.0 ± 13.0 years. Overall, 511 (65.8%) cases were benign, followed by adrenal metastases (n = 224, 28.8%), pheochromocytoma (n = 26, 3.3%), adrenal lymphoma (n = 9, 1.2%), and adrenal corticocarcinoma (ACC; n = 7, 0.9%). Hormonal evaluation revealed that 34.3% of bilateral adrenal lesions were functional. The primary etiologies of functional lesions were primary aldosteronism (16.6%, 129/777), and primary bilateral macronodular adrenocortical hyperplasia (PBMAH; 8.8%, 68/777). Patients with lymphoma and metastases were significantly older than those with benign nonfunctional lesions (60.4 ± 11.0 years vs. 54.5 ± 10.4 years and 57.9 ± 10.8 years vs. 54.5 ± 10.4 years, respectively; both P < 0.001). Lesions in patients with adrenal lymphoma, ACC, pheochromocytoma, metastases, congenital adrenal hyperplasia, tuberculosis, and Cushing's syndrome were significantly larger than benign nonfunctional lesions (all P < 0.001). CONCLUSION Benign adrenal lesions and metastases from the lungs are the most common causes of bilateral adrenal lesions. Primary aldosteronism and PBMAH are the most prevalent functional lesions. Moreover, patients with lymphoma or metastases are older and their masses are larger.

Abstract
Objective: To investigate the diagnostic value of preferentially expressed antigen in melanoma (PRAME) in differential diagnosis of benign and malignant cutaneous melanocytic lesions. Methods: Fifty-nine cases of melanoma (50 cases of skin primary melanoma, and 9 cases of metastatic melanoma) and 48 cases of melanocytic nevus (40 cases of common nevus and 8 cases of dysplastic nevus) were subject to PRAME immunohistochemistry staining.The difference of PRAME expression between melanoma and melanocytic nevus was analyzed. Results: Among the 50 patients with primary cutaneous melanoma, there were 23 males and 27 females ranging in age from 33 to 87 years (average age 62.4 years, median age 64.5 years). Among the 9 metastatic melanoma there were 7 males and 2 females ranging in age from 40 to 82 years (average age 64 years, median age 65 years). Twenty-six cases (26/50, 52.0%) of cutaneous primary melanoma and 4 cases (4/9) of metastatic melanoma showed diffuse positive PRAME staining. 40 cases (40/40, 100%) of common nevus and 8 (8/8) cases of dysplastic nevus were PRAME negative. Compared with melanocytic nevus group, the melanoma group included more cases with diffuse positive PRAME staining (P<0.05). The sensitivity and specificity of using PRAME to differentiate primary cutaneous melanoma from melanocytic nevus in the cohort is 52.0% and 100%. Conclusions: There is a significant difference in the expression of PRAME between melanoma and melanocytic nevus.Thus, PRAME can be used as an auxiliary diagnostic tool for differentiating benign from malignant cutaneous lesions.

Abstract
The tetanus has been eliminated in the pregnancy women and newborns in China. However, there is a gap for adult tetanus immunization, and the risk of tetanus infection cannot be ignored. In order to clearly understand the effect of the tetanus to human beings and the current use of tetanus immunological preparation for adult post-exposure prophylaxis, the incidence of the tetanus, the use status of tetanus immunological preparation and recommendations for post-exposure prophylaxis at home and abroad were reviewed and summarized, which may provide academic evidence for post-exposure prophylaxis procedures and use of tetanus immunological preparation.

Abstract
Abstract
Study question
Are mutations in cilia and flagella-associated protein 61 (CFAP61) associated with human male infertility?
Summary answer
Bi-allelic variants ([NM_015585.4: c.1654C>T (p.R552C) and c.2911G>A (p.D971N), c.144-2A>G and c.1666G>A (p.G556R)] in CFAP61 were identified as contributory genetics factor in severe oligoasthenoteratozoospermia (OAT).
What is known already
Cfap61 knockout mice were infertile due to multiple morphological abnormalities of the sperm flagella (MMAF). However, so far there is no direct evidence that mutations of CFAP61 cause OAT and male infertility.
Study design, size, duration
Variant screening was performed by whole-exome sequencing (WES) from 325 infertile patients with OAT and 392 fertile individuals. A knockout mouse model was generate to confirm the candidate disease-causing gene, intracytoplasmic sperm injection (ICSI) was used to evaluate the efficiency of clinical treatment.
Participants/materials, setting, methods
A total 325 OAT-affected patients and 392 men with normal fertility were recruited from China. WES was performed, followed by Sanger sequencing validation. In silico bioinformatics predictions and in vitro functional analyses were performed to evaluate the impacts of candidate disease-causing variants. Hematoxylin and eosin (H&E) staining, electron microscopy, and immunofluorescence assays were performed to evaluate the sperm morphology. Two OAT-affected men with CFAP61 variants were treated by ICSI, and pregnancy outcomes were followed.
Main results and the role of chance
We identified bi-allelic CFAP61 variants [NM_015585.4: c.1654C>T (p.R552C) and c.2911G>A (p.D971N), c.144-2A>G and c.1666G>A (p.G556R)] in two (0.62%) of the 325 OAT-affected men. In silico bioinformatics analysis predicted that all four variants were deleterious, and in vitro functional analysis confirmed the deleterious effects of the mutants. Notably, H&E staining and electron microscopy analyses of the spermatozoa revealed multiple morphological abnormalities of sperm flagella, the absence of central pair microtubules, and mitochondrial sheath malformation in sperm flagella from man with CFAP61 variants. Further immunofluorescence assays revealed markedly reduced CFAP61 staining in the sperm flagella. In addition, Cfap61-deficient mice showed the OAT phenotype, suggesting that loss of function of CFAP61 was the cause of OAT. Two individuals accepted ICSI therapy using their own ejaculated sperm, and one of them succeeded in fathering a healthy baby.
Limitations, reasons for caution
Limitations include the lack of in vivo data from the one of patients, and the exact molecular mechanism should be further investigated.
Wider implications of the findings
Our findings indicate that CFAP61 is essential for spermatogenesis and that bi-allelic CFAP61 variants lead to OAT and male infertility in humans and mice. In addition, our results show that ICSI treatment can be recommended for CFAP61-related OAT.

Abstract
All kingdoms of life produce essential nicotinamide dinucleotide NADP(H) using NAD kinases (NADKs). A panel of published NADK structures from bacteria, eukaryotic cytosol, and yeast mitochondria revealed similar tetrameric enzymes. Here, we present the 2.8-Å structure of the human mitochondrial kinase NADK2 with a bound substrate, which is an exception to this uniformity, diverging both structurally and biochemically from NADKs. We show that NADK2 harbors a unique tetramer disruptor/dimerization element, which is conserved in mitochondrial kinases of animals (EMKA) and absent from other NADKs. EMKA stabilizes the NADK2 dimer but prevents further NADK2 oligomerization by blocking the tetramerization interface. This structural change bears functional consequences and alters the activation mechanism of the enzyme. Whereas tetrameric NADKs undergo cooperative activation via oligomerization, NADK2 is a constitutively active noncooperative dimer. Thus, our data point to a unique regulation of NADP(H) synthesis in animal mitochondria achieved via structural adaptation of the NADK2 kinase.

Abstract
Objective: To observe the effect of liraglutide on the correlation between nucleotide-binding oligomerization domain-like receptor family pyrin domain-containing protein 3 (NLRP3) infl ammasome and nonalcoholic fatty liver disease (NAFLD). Methods: Thirty-nine NAFLD cases (group N) and thirty-nine healthy subjects (group C) were selected from the physical examination center, and their general data were collected to determine the serum levels of NLRP3, IL-1β, and IL-18. The differences and correlations were analyzed between the two sets of indicators. Thirty male SD rats were randomly divided into normal (NC, n=10) and high-fat diet group (HF, n=20). The normal group were fed with normal diet and high-fat diet group were fed with high-fat diet. After 12 weeks of feeding, HF group was randomly divided into HF group (n=10) and liraglutide group (100L, n=10), and were given 0.5 ml/kg sterile isotonic saline and 100 g/kg liraglutide subcutaneously twice a day, respectively. Four weeks later, serum biochemical indicators, liver NLRP3 infl ammasome protein expression, and infl ammatory cytokine conditions were detected in each group. Statistical analysis was performed using t test, oneway analysis of variance (ANOVA) or χ2 test. Results: There were no statistically signifi cant differences between N and C group in terms of age, gender, diastolic blood pressure, glycosylated hemoglobin, mean platelet volume, erythrocyte distribution width, serum low-density lipoprotein cholesterol (HDL-Ch), total cholesterol, and total bileacid. Compared with group C, group N had elevated systolic blood pressure, body mass index (BMI), fasting blood glucose, blood creatinine, alkaline phosphatase (ALP), NLRP3, interleukin (IL)-1β, IL-18, TG, blood uric acid, γ-glutamyltransferase (GGT), alanine aminotransferase (ALT), aspartate aminotransferase (AST), and white blood cell counts, while HDL-Ch and total bilirubin were depleted than group C, and the difference was statistically significant (P< 0.05). NLRP3 was positively correlated with systolic blood pressure, BMI, fasting blood glucose, serum creatinine, IL-1β, IL-18, triglycerides, serum uric acid, GGT, ALT, AST, but negatively correlated with total bilirubin and HDL-Ch, and the difference was statistically signifi cant. Compared with NC group, HF group had significantly increased body mass, liver mass, serum biochemical indicators (triglycerides, AST, ALT), liver NLRP3 inflammasome protein expression, and inflammatory cytokines. After treatment with liraglutide, 100L group indicators were signifi cantly decreased when compared to HF group. Conclusion: Compared with healthy subjects, the infl ammation-related indicators, body mass, blood lipids and liver function-related indicators are signifi cantly changed in patients with NAFLD, which is also consistent with the results of rat model study. Liraglutide treatment had improved NAFLD to certain extent in NAFLD rats, so NLRP3 regulation may be one of the mechanisms to improve liver inflammation and steatosis.

Abstract
Esophageal squamous cell carcinoma (ESCC) is a deadly disease that seriously affects global public health. The aim of the present study was to explore the role of integrin subunit α3 (ITGA3) in ESCC and investigate its detailed molecular mechanisms. Using reverse transcription–quantitative PCR (RT-qPCR) and western blotting, the mRNA and protein expression of ITGA3 in cell lines was detected. In addition, a series of cellular biological experiments, including Cell Counting Kit-8, wound-healing, Transwell and TUNEL assays, were used to evaluate proliferation, migration, invasion and apoptosis, respectively. Furthermore, western blotting was used to measure the expression of corresponding proteins. ITGA3 was found to be upregulated in ESCC cell lines (ECA109 and TE1). It was also found that ITGA3 silencing inhibited the proliferation, migration, invasion and autophagy of ECA109 and TE1 cells but promoted their apoptosis. In addition, ITGA3 silencing was found to inhibit the FAK/PI3K/AKT signaling pathway. In conclusion, ITGA3 knockdown suppressed cell proliferation, invasion, migration and autophagy in ECA109 and TE1 cells, suggesting that ITGA3 may be a potential therapeutic target for the treatment of ESCC.

Abstract
OBJECTIVE Patients with hypoparathyroidism always present with recurrent tetany caused by hypocalcemia. These patients are usually misdiagnosed with epilepsy and incorrectly treated with anti-epileptic drugs. This research analyzed clinical data about 22 patients with hypoparathyroidism misdiagnosed as epilepsy and summarized the clinical experience for reducing misdiagnosis and incorrect therapy about hypoparathyroidism. METHOD Totally 160 patients with hypoparathyroidism, administrated to the First Medical Center of Chinese PLA General Hospital from January 1st, 2008, to July 1st, 2021, were enrolled in this report. Clinical data about 22 patients initially misdiagnosed with epilepsy were analyzed. RESULTS Of the 160 cases with hypoparathyroidism, 22 patients (12 males and 10 females) were misdiagnosed with epilepsy in local hospitals. The misdiagnosis rate was 13.75% and the median duration of misdiagnosis was 8.0 (2.0, 14.8) years. The clinical manifestations of the 22 patients misdiagnosed as epilepsy included tetany 81.8% (18/22), disturbance of consciousness 27.3% (6/22), limb numbness 13.6% (3/22), limb weakness 27.3% (6/22), mental and behavioral abnormality 9.1% (2/22), and memory impairment 13.6% (3/22), etc. Electroencephalogram (EEG) was performed in 9 cases, which presented as slow wave and spike-slow complex wave in 3 cases, slowing down of θ and δ band background in 2 cases and normal EEG in 4 cases. Out of the 15 cases that underwent head computed tomography (CT) scan, in which 13 cases had intracranial calcification. Anti-epileptic drugs were used to treat 22 patients, of which 17 patients were treated with two kinds of drugs. With calcium and calcitriol supplement in all these 22 patients, the anti-epileptic drugs were gradually reduced and withdrawn in 17 cases. In the other 5 cases with secondary epilepsy, the type of anti-epileptic drugs was reduced to one and the clinical condition improved obviously. CONCLUSION The clinical manifestations of hypoparathyroidism are complex and usually be misdiagnosed as primary epilepsy. Detection of serum calcium, phosphorus and parathyroid hormone is very important to avoid misdiagnosis and incorrect therapy about hypoparathyroidism.

Abstract
BackgroundTakayasu’s arteritis (TA) is an autoimmune vasculitis that frequently occur in young women.Multiple previous studies have demonstrated that accelerated atherosclerotic changes were commonly found in TA patients[1-4].More specifically, data indicated that as much as 27% of all TA patients developed carotid artery plaque, while which was only 2% in the age- and sex-matched healthy individuals[1]. In addition, up to 20% of TA patients developed stroke and/or transient ischemic attack(TIA), which both have been known to be associated with atherosclerotic lesions[1-3]. Inflammation of the vascular wall may promotes atherosclerosis (As) in TA,which accelerates the development of As.Higher triglyceride (TG)/HDL-C ratio was found to be associated with presence of endothelial dysfunction and As[5].ObjectivesThis study aimed to identify the risk factors associated with the development of atherosclerosis in TA.MethodsThis retrospective study enrolled a total of 101 TA patients. All patients were divided into two groups according to the absence or presence of atherosclerosis(43 vs 58). Baseline demographic features and clinical characteristics were compared between two groups. A logistic model was applied to determine the risk factors associated with the development of atherosclerosis.ResultsOur data suggested that the disease duration of patients in the atherosclerosis group was significantly longer than that of patients in the non-atherosclerosis group [96(18.00,180.00) vs 48.00(12.00,111.00) months] (p=0.015). In addition, the average age of patients with atherosclerosis was significantly older compared to patients without atherosclerosis [44.00(38.00,48.00)vs 28.50(24.00,37.00)years] (p<0.001). Logistic regression analysis showed that the risk of developing atherosclerosis increased by 9.2% per 1 year increase in thedisease duration(p=0.005, OR 1.092,95%CI:1.027-1.162).Patients with TG/HDL-C ratio more than 0.8875 were associated with a 5.861fold increase of risk developing atherosclerosis(p<0.001, 95%CI:2.299-14.939).ConclusionOur study indicated that prolonged disease duration and elevated TG/HDL-C ratio are associated with the development of atherosclerosis in TA patients.References[1]Seyahi E, Ugurlu S, Cumali R, Balci H, Seyahi N, Yurdakul S, et al.

Abstract
BackgroundTakayasu’s arteritis(TA)can involve coronary artery lesions. The pathogenesis is complex and lacks the best treatment strategy.The coronary artery lesions were typical seen in the ostia of the left and right coronary arteries which were major risk factors for sudden death and ischemia heart failure[1-2].Coronary artery lesions is an important predictor of poor prognosis in TA patients.The incidences of coronary artery lesions were more common in type V TA patients [3-4].The prevalence of metabolic syndrome and its related characteristics (including dyslipidemia, diabetes and hyperinsulinemia) in TA patients are higher compared with healthy people[5].Thus,under the action of vascular inflammation and traditional risk factors, coronary artery stenosis or even occlusion occurs earlier, which can lead to MACE events.ObjectivesThe aim of our study is to investigate the risk factors and prognosis of coronary artery lesions in TA patients.MethodsThis retrospective study enrolled a total of 120 TA patients.All patients were divided into two groups according to the absence or presence of coronary artery lesions in TA patients (61 vs 59). A logistic model was applied to determine the risk factors associated with the incidence of coronary artery lesions in TA patients.According to the before and after imaging comparison of TA with coronary artery lesions, the influencing factors of improving TA with coronary artery lesions were analyzed.ResultsThe incidence of coronary artery lesions in TA patients increased by 1.618 times for each additional year (p=0.034, OR1.618,95%CI: 1.036-2.529). History of hyperlipidemia indicated 10.124 fold higher risk of coronary artery lesions in TA patients(p=0.003, OR10.124,95%CI: 2.159-47.483).In the follow-up of TA with coronary artery lesions, 27 patients had coronary CTA results before and after comparison. It was found that 11 patients had remission of coronary artery lesions and 16 patients had no remission of coronary artery lesions. The age in the group with improved coronary imaging was significantly younger than that in the group without improved coronary imaging[(39.00±9.81 vs (47.44±10.06) years,p=0.041)].TNF-α and interleukin-6 were significantly higher in the group with improved coronary imaging than in the group without improved coronary imaging[(26.40(10.08,165.90) vs 7.80(6.73,21.70)pg/dl,p=0.047;12.50(5.83,19.30) vs3.71(2.80,4.40)pg/dl,p<0.001].Numano type V (75.00% vs 27.27%, p = 0.022) and vascular calcification (56.25% vs 9.09%, p= 0.018) were significantly higher than those in the group without improved coronary imaging, while numano type IIb in the group with improved coronary imaging was significantly higher than that in the group without improved coronary imaging(45.45% vs 6.25%,p=0.027).ConclusionHyperlipidemia and age are the risk factors of coronary artery lesions in Takayasu arteritis.Numano type V and vascular calcification are not conducive to the improvement of TA with coronary artery lesions.All patients with TA of numano type IIb should be screened for coronary artery. Early control of inflammation is more conducive to the imaging improvement of arteritis coronary lesions.References[1]Matsubara, O, Kuwata, T, Nemoto, T, et al., Coronary artery lesions in Takayasu arteritis: pathological considerations, Heart and vessels.

Abstract
Interleukin-37 (IL-37) is an effective anti-inflammatory factor and acts through intracellular and extracellular pathways, inhibiting the effects of other inflammatory cytokines, such as IL-1β, IL-6, and tumor necrosis factor-α (TNF-α), thereby exerting powerful anti-inflammatory effects. In numerous recent studies, the anti-inflammatory effects of IL-37 have been described in many autoimmune diseases, colitis, and tumors. However, the current research on IL-37 in the field of the central nervous system (CNS) is not only less, but mainly for clinical research and little discussion of the mechanism. In this review, the role of IL-37 and its associated inflammatory factors in common CNS diseases are summarized, and their therapeutic potential in CNS diseases identified.

Abstract
Background To determine the efficacy and safety of umbilical cord-derived mesenchymal stem cells (UC-MSCs) in Chinese adults with type 2 diabetes mellitus (T2DM). Methods In this single-center, double-blinded, randomized, placebo-controlled phase II trial, 91 patients were randomly assigned to receive intravenous infusion of UC-MSCs (n = 45) or placebo (n = 46) three times with 4-week intervals and followed up for 48 weeks from October 2015 to December 2018. The primary endpoint was the percentage of patients with glycated hemoglobin (HbA1c) levels of < 7.0% and daily insulin reduction of ≥ 50% at 48 weeks. Additional endpoints were changes of metabolic control, islet β-cell function, insulin resistance, and safety. Results At 48 weeks, 20% of the patients in the UC-MSCs group and 4.55% in the placebo group reached the primary endpoint (p < 0.05, 95% confidence interval (CI) 2.25–28.66%). The percentage of insulin reduction of the UC-MSCs group was significantly higher than that of the placebo group (27.78% versus 15.62%, p < 0.05). The levels of HbA1c decreased 1.31% (9.02 ± 1.27% to 7.52 ± 1.07%, p < 0.01) in the UC-MSCs group, and only 0.63% in the placebo group (8.89 ± 1.11% to 8.19 ± 1.02%, p˃0.05; p = 0.0081 between both groups). The glucose infusion rate (GIR) increased significantly in the UC-MSCs group (from 3.12 to 4.76 mg/min/kg, p < 0.01), whereas no significant change was observed in the placebo group (from 3.26 to 3.60 mg/min/kg, p ˃ 0.05; p < 0.01 between both groups). There was no improvement in islet β-cell function in both groups. No major UC-MSCs transplantation-related adverse events occurred. Conclusions UC-MSCs transplantation could be a potential therapeutic approach for Chinese adults with T2DM. Trial registration This study was registered on ClinicalTrials.gov (identifier: NCT02302599). Supplementary Information The online version contains supplementary material available at 10.1186/s13287-022-02848-6.

Abstract
Objective: To evaluate the safety and efficacy of intra-arterial tirofiban infusion during endovascular reperfusion therapy in patients with acute cardiogenic cerebral embolism. Methods: Clinical data of 72 patients with acute cardiogenic cerebral embolism caused by large artery occlusion were retrospectively analyzed in Department of Neurology, Strategic Support Force Medical Center from August 2015 to August 2020.Among those, 52 patients were treated with intra-arterial tirofiban, the other 20 patients were treated with control medication. The baseline characteristics, modified thrombolysis in cerebral infarction (mTICI) score of responsible vessels, modified Rankin scale (mRS) score 90 days after operation, incidence of symptomatic intracranial hemorrhage and mortality were evaluated and compared in two groups. Results: The proportion of effective recanalization of the offending vessels (mTICI≥2b) in tirofiban group was higher than that in control group (92.3% vs. 75.0%), but the difference was not statistically significant (P=0.104). At 90 days after operation, the rate of patients with good prognosis (mRS≤2) in tirofiban group (61.5%) was significantly higher than that in control group (35.0%) (P<0.05). The incidence of symptomatic intracranial hemorrhage and mortality were comparable between the two groups (P>0.05). Conclusion: Intra-arterial tirofiban infusion in patients with acute cardiogenic cerebral embolism is effective and feasible, which improves the prognosis without increasing the risk of intracranial bleeding complications.

Abstract
Objective: To investigate the effects and mechanism of hydrogen peroxide (HP) pretreatment with low molarity on oxidative stress induced apoptosis of mouse bone marrow mesenchymal stem cells (BMSCs). Methods: The experimental research methods were used. BMSCs were isolated and cultured from two 2-week-old male BALB/c mice by the whole bone marrow culture method. The 3rd-7th passages of cells in logarithmic growth phase were used for the experiments after identification.

Abstract
AbstractHigh-dimensional covariance matrix estimation plays a central role in multivariate statistical analysis. It is well-known that the sample covariance matrix is singular when the sample size is smaller than the dimension of the variable, but the covariance estimate must be positive-definite. This motivates some modifications of the sample covariance matrix to preserve its efficient estimation of pairwise covariance. In this paper, we modify the sample correlation matrix using the Bagging technique. The proposed Bagging estimator is flexible for general continuous data. Under some mild conditions, we show theoretically that the Bagging estimator can ensure positive-definiteness with probability one in finite samples. We also prove the consistency of the bootstrap estimator of Pearson correlation and the consistency of our Bagging estimator when the dimension p is fixed. Simulation results and a real application are provided to demonstrate that our method strikes a better balance between RMSE and likelihood, and is more robust, than other existing estimators.

Abstract
Absorbent pads with antioxidant and pH-responsive color changing functions have been developed based on polyvinyl alcohol (PVA), agarose (AG), and purple sweet potato anthocyanins (PSPA), aiming for fresh keeping and freshness indication of meat. The effects of PSPA content on the structure, physical properties, and colorimetric response towards pH changing of pads were evaluated. The results showed that PSPA interacted with PVA and AG and influenced the crystallinity, thermal stability and micro-morphology of pads. The increase of the PSPA content from 3% to 12% improved the strength and DPPH radical scavenging activity of the pads, but reduced the swelling ratio. Significant color change of the pads was observed when pH increased from 3 to 10, and the pad containing 9% PSPA presented the most distinguishable color change with the change of pH. When applied as an absorbent pad for minced meat packaging, the pad indicated the real-time spoilage of the meat through obvious color change, and also extended the shelf life by at least 24 h. Therefore, the dual-functional pad shows great potential to be applied as a smart and active packaging for fresh meat, which would play an important role in ensuring food safety and improving food storage quality.

Abstract
From 2011 to 2020, there were 111 213 cases of rabies exposed people recruited from the rabies immunization clinic of a hospital in Beijing. The monthly distribution of patients in each year was not statistically significant (P>0.05). The distribution of patients showed remarkable seasonality, with the exposure peak from May to October. The ratio of male to female was 1∶1.3. The majority of patients were aged 20-29 years old (39.1%) and in-service personnel (56.5%). Level-Ⅱ wounds (84.2%) were more common than level-Ⅲ wounds (14.9%). The number of visits to level-Ⅲwounds increased rapidly since 2017. The most common injured body part was hand (60.7%). Dogs were the most common animal for injuries (60.6%), followed by cats (32.3%), of which most were host animals (75.5%). The vaccination rate from 2016 to 2020 [49.8% (24 276/48 703)] was significantly higher than that from 2011 to 2015[18.6% (6 559/35 272)](χ²=8597.18, P<0.001).

Abstract
OBJECTIVE China is a developing country with urban-rural disparities and accelerating population aging. Therefore, quantifying the effects of population aging on the cancer mortality burden is urgently needed. METHODS Using data from China's death surveillance datasets (2004-2017), we decomposed and quantified the effects of population aging and factor variations on cancer mortality rates in urban and rural China during 2004-2017 through a decomposition method. R ratios were used to assess the extent of the mortality decreases attributable to factor variations offsetting the increases attributable to population aging for 4 aging-related cancers (lung, colorectal, esophageal, and stomach cancer). RESULTS Overall, population aging has led to continued increases in cancer mortality rates in China during 2004-2017 (mortality rates attributable to population aging: 8.63/100,000 for urban men, 4.21/100,000 for urban women, 11.95/100,000 for rural men, and 5.66/100,000 for rural women). The 4 cancers displayed 3 patterns. The mortality rates from lung cancer in rural China and from colorectal cancer nationwide increased because of both population aging and factor variations. Population aging was primarily responsible for the growing mortality due to lung cancer in urban areas. However, for esophageal and stomach cancer, the effect of population aging was not dominant, thus resulting in decreases in mortality rates. CONCLUSIONS Health resource allocation should prioritize areas or cancers more adversely affected by population aging. The burden of cancer will continue to increase in the future, because of rapid population aging, but can still be offset or even reversed with enhanced cancer control and prevention.

Abstract
OBJECTIVE To elucidate the impact of acute-phase protein serum amyloid A (aSAA) on microvascular invasion (MVI) and early recurrence in hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC). METHODS HBV-related HCC patients (n = 192) undergoing liver resection were included in the study. The protein levels of aSAA were analyzed by immunohistochemical staining in 172 tumor specimens, and further detected via western blotting in HCC and their corresponding portal vein tumor thrombus (PVTT) (n = 20). Cox and logit regression analysis was performed. Exploratory subgroup analysis was used to balance the potential confounders. RESULTS HBV-related HCC patients with high aSAA levels tended to have high HBV-DNA loads. Logit and Cox regression analyses revealed high expression of aSAA is an independent risk factor not only for MVI (OR 5.384, 95% CI 2.286-13.301, P < 0.001) but also for early recurrence (HR 6.040, 95% CI 1.970-18.540, P = 0.002), overall recurrence (HR 3.720, 95% CI 2.140-6.450, P < 0.001), and overall survival (HR 4.15, 95% CI 2.380-7.230, P < 0.001). Subgroup analysis showed that the effects of aSAA were consistent across all subgroups examined. Additionally, the aSAA protein level was significantly higher in PVTT than that in its corresponding tumor specimen. A high HBV-DNA level and large tumor size were the independent risk factors for early HCC recurrence in patients with high levels of aSAA. CONCLUSIONS High expression of aSAA was an independent risk factor for MVI and early tumor recurrence in HBV-related HCC patients after liver resection. The aSAA protein level could thus be a promising biomarker for predicting MVI and early recurrence in these patients.

Abstract
Anaerobic digestion is achieved through cooperation among various types of microorganisms, and the regulation of microbial communities is key to achieving stable system operation. In this study, the r/K selection theory was adopted to examine the system performance and microbial characteristics in anaerobic reactors with different operating modes (continuous-flow reactors, CFRs; sequencing batch reactors, SBRs) and sludge retention times (25 and 10 days). Four lab-scale reactors (CFR25d, CFR10d, SBR25d, and SBR10d) were operated. In the cycle reaction, CFR25d achieved the highest methane yield (678.0 mL/L) and methane production rate (140.8 mL/(L·h)); while those in CFR10d were the lowest, which could have been due to an accumulation of volatile fatty acids. CFR could wash out r-strategists efficiently, such as Methanosarcina. CFR25d and CFR10d significantly enriched the K-strategist Geobacter, with the relative abundances of 34.0% and 72.6%, respectively. In addition, the hydrogenotrophic methanogens of Methanolinea and Methanospirillum (K-strategists) dominated in CFR25d and CFR10d. Methanobacterium adapted to the diverse operational conditions, but the slow grower Methanosaeta only accounted for 0.9% in CFR10d. Failure to enrich propionate oxidizers resulted in a functional absence of propionate degradation in the CFRs.

Abstract
AIM To assess the relationship between gadolinium deposition in the brain and various gadolinium-based contrast agents (GBCAs) and to explore confounding variables. METHODS The study group included 87 patients with multiple enhanced brain magnetic resonance imaging (MRI) examinations of which 48 patients were in the linear GBCA group (33 patients in gadopentetate dimeglumine group and 15 patients in gadobenate dimeglumine group) and 39 patients in the macrocyclic GBCA group (22 patients in gadobutrol group and 17 patients in gadoterate meglumine group). The control group included 87 normal participants who were matched regarding age, sex, MRI machine and imaging sequences to the study cohort. T1 signal intensity (SI) ratios of the dentate nucleus to the pons (DN/pons) and of the globus pallidus to the frontal white matter (GP/FWM) in both groups were calculated and compared. The relationships between SI ratios and confounding variables were analysed. RESULTS Significant differences were detected between two linear GBCA groups and control groups in T1 SI ratios of the DN/pons and GP/FWM (all p<0.001). There were no differences for two the macrocyclic GBCA groups compared with matching control groups (all p>0.05). T1 SI ratios of the linear GBCA group were significantly higher than those of the macrocyclic GBCA group (p<0.001). In the linear GBCA group, the T1 SI ratios of the DN/pons correlated moderately positively with the number of GBCA administrations (r=0.643, p<0.001), and MRI machine and sequence used. CONCLUSIONS Increased T1 SI could be observed after repeated administrations of linear GBCA. T1 SI of the DN correlated with the number of linear GBCA administrations, and detection might be affected by MRI machine and sequence.

Abstract
Caleosin is a lipid droplet-binding protein involved in maintenance of the lipid droplet structure and in signal transduction. However, the role of caleosin proteins in stress resistance is limited. Here, we report data for a rice caleosin protein gene, OsClo5, involved in cold stress tolerance via influence and regulation of the JA signalling pathway. Overexpression lines and RNAi lines of OsClo5 were subjected to cold stress and recovery to measure electrolyte leakage and survival rate. Changes were also detected in the genome-wide transcriptome of OsClo5 overexpressed plants. OsClo5 is located mainly in lipid droplets and expressed in all tissues tested. Its expression was upregulated by various stress conditions when subjected to cold treatment. Overexpression of OsClo5 decreased cold tolerance, and RNAi lines of OsClo5 had higher survival than WT seedlings. OsClo5 inhibited one jasmonate biosynthetic gene and several jasmonate ZIM domain (JAZ) genes, which were upregulated in response to cold stress. OsClo5 is a constitutively expressed caleosin protein that regulates plant cold resistance through inhibition of jasmonate signalling and JA synthesis.

Abstract
BACKGROUND AND OBJECTIVE Mild autonomous cortisol secretion (MACS) presents with a marked female preponderance, but whether the sex difference in its distribution has any relevance to the presentation and outcome of the disease is unknown. The aim of this study was therefore to compare biochemical indices of hypercortisolism and impaired glucose metabolism between male and female patients with MACS. METHOD We enrolled a total of 98 patients with autonomous/possible autonomous cortisol secretion in our study, and indices of hypercortisolism and glucose metabolism were collected and compared between the male and female patients. Logistic regression models were used to evaluate the association between sex and cortisol-secretory ability, as well as between the latter and glucose metabolism. In addition, we conducted further stratified analyses according to the degree of autonomous cortisol secretion and menopausal status. RESULTS Cortisol levels at 00:00 and 08:00 h after a 1-mg dexamethasone suppression test (DST) and low-dose DST were significantly higher in female than in male MACS patients, and the inhibition rate of 1-mg DST was lower in the women than in the men. This significant difference still remained after adjusting for age, BMI, and the course of the disease. Logistic regression analysis revealed a significant association between autonomous cortisol secretion and fasting C-peptide, as well as with the C-peptide-to-glucose ratio in females relative to male patients. In addition, stratified analyses indicated that this association was observed only among women with autonomous cortisol secretion and who were premenopausal. CONCLUSION The level of autonomic cortisol secretion in female patients with MACS was higher than in male patients, and the association between autonomous cortisol secretory ability and glucose homeostasis was only noted in patients with autonomous cortisol secretion and in premenopausal women. This phenomenon will, however, require closer follow-up.

Abstract
Objective: To provide insight into the diagnosis for clinicians, the clinical characteristics, diagnosis and treatment history of 3 patients with 21-hydroxylase deficiency (21-OHD) and testicular adrenal rest tumors (TART) were analyzed. Methods: The clinical, laboratory and imaging data of 3 male patients with 21-OHD and TART, confirmed with CYP21 gene sequencing, from May 2010 to May 2021 in the First Medical Center of Chinese PLA General Hospital were analyzed retrospectively. The treatment strategy and clinical outcome were followed up. Results: All the 3 patients were first diagnosed with bilateral adrenal mass at the age of 27-42 years old. They were 145-162 cm tall. The levels of progesterone, 17-hydroxyprogesterone, and adrenocorticotropic hormone (ACTH) of the 3 patients were relatively high, and that of luteinizing hormone (LH) and follicle-stimulating hormone (FSH) of the 3 patients were low. Testosterone level of 1 patient was significantly elevated, and that of the other 2 patients was below the lower limit of normal range. Testicular ultrasound showed heterogeneous hyperechoic masses in both testes. CT of the adrenal glands showed bilateral adrenal enlargement with mass. All 3 patients were treated with dexamethasone. After 4-96 months of follow-up, 17-hydroxyprogesterone level was kept above the median normal level. One of the patients got married and had a baby after treatment. The sizes of adrenal hyperplasia and testicular masses reduced to various degrees with the change of the testicular masses being proportional to that of adrenal hyperplasia. Conclusions: Patients with 21-OHD are prone to have TART, leading to the impaired testicular function. Early glucocorticold therapy is beneficial to the reduction of TART and restoration of testicular function.

Abstract
BACKGROUND Patients with normoalbuminuria and a reduced estimated glomerular filtration rate (eGFR) account for a considerable proportion of type 2 diabetes patients. The aim of this research was to investigate the epidemiological and clinical characteristics of normoalbuminuric kidney disease in a Chinese population. METHODS We included 8131 diabetic patients from a multicenter prospective study in China. Based on eGFR and urinary albumin-to-creatinine ratio (UACR), participants were stratified into four groups-normal albuminuria, albuminuria, normoalbuminuria with eGFR < 60 mL/min/1.73 m2 , and albuminuria with eGFR < 60 mL/min/1.73 m2 . Clinical parameters and characteristics of patients with normoalbuminuria and eGFR < 60 mL/min/1.73 m2 were retrospectively analyzed. RESULTS A total of 1060 out of 8131 individuals with diabetes had decreased eGFR (<60 mL/min/1.73 m2 ). Normoalbuminuria accounted for 63.3% of participants with eGFR < 60 mL/min/1.73 m2 , and microalbuminuria and macroalbuminuria accounted for 30.1% and 6.3%, respectively. Patients with normoalbuminuria and reduced eGFR were more frequently male, older, and had higher levels of triglycerides than patients with normal albuminuria and eGFR. We also detected a correlation between lower extremity arterial disease, newly diagnosed diabetes, and normoalbuminuria-reduced eGFR. Compared with participants with both albuminuria and eGFR decline, those with normoalbuminuria had better metabolic indicators, including systolic blood pressure and glycosylated hemoglobin, and shorter diabetes duration. Even in the normal range, UACR has a significant correlation with the risk of eGFR insufficiency. CONCLUSIONS Normoalbuminuric renal insufficiency, characterized by male sex, older age, a higher level of triglyceride levels, and a higher risk of lower extremity arterial disease, accounted for a dominant proportion of diabetic patients with eGFR decline.

Abstract
Double-stranded RNA (dsRNA), a hallmark viral material that activates antiviral interferon (IFN) responses, can appear in human cells also in the absence of viruses. We identify phosphorothioate DNAs (PS DNAs) as triggers of such endogenous dsRNA (endo-dsRNA). PS DNAs inhibit decay of nuclear RNAs and induce endo-dsRNA via accumulation of high levels of intronic and intergenic inverted retroelements (IIIR). IIIRs activate endo-dsRNA responses distinct from antiviral defense programs. IIIRs do not turn on transcriptional RIG-I/MDA5/IFN signaling, but they trigger the dsRNA-sensing pathways of OAS3/RNase L and PKR. Thus, nuclear RNA decay and nuclear-cytosolic RNA sorting actively protect from these innate immune responses to self. Our data suggest that the OAS3/RNase L and PKR arms of innate immunity diverge from antiviral IFN responses and monitor nuclear RNA decay by sensing cytosolic escape of IIIRs. OAS3 provides a receptor for IIIRs, whereas RNase L cleaves IIIR-carrying introns and intergenic RNAs.

Abstract
We report the observation of the unidirectional spin Hall magnetoresistance (USMR), which depends on the current or magnetization direction, in heavy-metal-ferromagnetic-insulator bilayer, Pt-Y_{3}Fe_{5}O_{12} (YIG). This USMR is apparently not caused by the mechanisms established in metallic bilayer, in which the ferromagnetic layer is required to be electrically conductive. From the magnetic field, current, temperature, and YIG thickness dependent measurements, the USMR is attributed to the asymmetric magnon creation and annihilation induced by the spin-orbit torque. This asymmetry and the resultant USMR are further revealed by the micromagnetic simulations combined with the spin-orbit torque and the spin drift-diffusion model. Our finding exhibits a nonlinear manipulation of magnons with the charge current.

Abstract
Amyloid-β (Aβ) accumulating is considered as a causative factor for formation of senile plaque in Alzheimer’s disease (AD), but its mechanism is still elusive. The Nicotinamide mononucleotide adenylyltransferase 2 (Nmnat2), a key redox cofactor for energy metabolism, is reduced in AD. Accumulative evidence has shown that the decrease of α-secretase activity, a disintegrin and metalloprotease domain 10 (ADAM10), is responsible for the increase of Aβ productions in AD patient’s brain. Here, we observe that the activity of α-secretase ADAM10 and levels of Nmnat2 are significantly decreased, meanwhile there is a simultaneous elevation of Aβ in Tg2576 mice. Over-expression of Nmnat2 increases the mRNA expression of α-secretase ADAM10 and its activity and inhibits Aβ production in N2a/APPswe cells, which can be abolished by Compound C, an AMPK antagonist, suggesting that AMPK is involved in over-expression of Nmnat2 against Aβ production. The further assays demonstrate that Nmnat2 activates AMPK by up-regulating the ratio of NAD+/NADH, moreover AMPK agonist AICAR can also increase ADAM10 activity and reduces Aβ1-40/1-42. Taken together, Nmnat2 suppresses Aβ production and up-regulates ADAM10 in AMPK activity-dependent manner, suggesting that Nmnat2 may serve as a new potential target in arresting AD.

Abstract
We aimed to explore the role of miR-21-5p in the inhibitory effects of astragaloside IV (As-IV) on hypoxia/reoxygenation injury-induced apoptosis of type II alveolar epithelial cells. Rat type II alveolar epithelial cells RLE-6TN were cultured in vitro and randomly divided into control (C), hypoxia/reoxygenation injury (H/R), As-IV and miR-21-5p-siRNA + As-IV groups (n = 6). H/R model was established by 24 h of hypoxia and 4 h of reoxygenation. As-IV group was given 1 nmol/L As-IV and incubated for 1 h before modeling. MiR-21-5p-siRNA + As-IV group was transfected with 50 nmol/L miR-21-5p-siRNA. After 48 h, they were incubated with 1 nmol/L As-IV for 1 h before modeling. Cell viability was detected by cell counting kit-8 assay, and apoptosis rate was detected by flow cytometry. The expression levels of TLR4 and NF-κB were measured by immunofluorescence assay. The targeting relationship between miR-21-5p and TLR4 was determined by luciferase assay. Compared with H/R group, the cell viability, miR-21-5p, bax and cleaved caspase-3 expressions of As-IV group increased, apoptosis rate and Bcl-2 expression decreased, and TLR4 and NF-κB expressions were down-regulated (P < 0.05). Compared with As-IV group, the cell viability, miR-21-5p, bax and cleaved caspase-3 expressions of miR-21-5p-siRNA + As-IV group decreased, apoptosis rate and Bcl-2 expression increased, and the expressions of TLR4 and NF-κB were up-regulated (P < 0.05). As-IV up-regulates miR-21-5p expression, inhibits the TLR4/NF-κB signaling pathway and suppresses the apoptosis of type II alveolar epithelial cells during hypoxia/reoxygenation injury.

Abstract
Objective: To investigate the incidence and determinants of vaccine hesitancy towards national immunization program in China and understand the current status of parents' hesitancy to different vaccines used in national immunization program. Methods: A cross-sectional survey was conducted in Beijing, Sichuan and Gansu. The methods of proportional probability sampling and convenience sampling were used to select the eligible study subjects for questionnaire surveys. Results: A total of 3 592 parents were enrolled in the study, in whom 38.22% fully accepted all the vaccines, 59.35% agreed to let their children to receive all the vaccines but showed slight concern, and 2.42% had hesitancy to the vaccines. The vaccine with the most hesitancy was polio vaccine (0.89%), followed by diphtheria pertussis tetanus vaccine (0.70%) and hepatitis A vaccine (0.64%). The dominant reason for vaccine hesitancy was the risk-benefit perception of vaccination (31.03%), followed by the low awareness of the parents (21.84%) and the inconvenience caused by distance and time (21.84%). Conclusions: The incidence of vaccine hesitancy towards national immunization program was low in parents in China, but over 50% of the parents showed concern to the vaccines. It is essential to improve the service quality of national immunization program and strengthen the health education about the vaccination to reduce the incidence of vaccine hesitancy in parents.
