Abstract
BACKGROUND Benralizumab is indicated as add-on therapy in patients with uncontrolled, severe eosinophilic asthma; it has not yet been evaluated in a large Asian population with asthma in a clinical trial. OBJECTIVE To evaluate the efficacy and safety of benralizumab in patients with severe asthma in Asia. METHODS MIRACLE (NCT03186209) was a randomized, Phase 3 study in China, South Korea, and the Philippines. Patients aged 12-75 years with severe asthma receiving medium-to-high-dose inhaled corticosteroid/long-acting β2-agonists, stratified (2:1) by baseline blood eosinophil count (bEOS) (≥300/μL; <300/μL), were randomized (1:1) to benralizumab 30 mg or placebo. Endpoints included annual asthma exacerbation rate (AAER; primary endpoint), change from baseline at Week 48 in pre-bronchodilator (BD) forced expiratory volume in 1 second (pre-BD FEV1) and total asthma symptom score (TASS). Safety was evaluated ≤ Week 56. RESULTS Of 695 patients randomized, 473 had baseline bEOS ≥300/μL (benralizumab n = 236; placebo n = 237). In this population, benralizumab significantly reduced AAER by 74% (rate ratio 0.26 [95% CI 0.19, 0.36], p < 0.0001) and significantly improved pre-BD FEV1 (least squares difference [LSD] 0.25 L [95% CI 0.17, 0.34], p < 0.0001) and TASS (LSD -0.25 [-0.45, -0.05], p = 0.0126) versus placebo. In patients with baseline bEOS <300/μL, there were numerical improvements in AAER, pre-BD FEV1, and TASS with benralizumab versus placebo. The frequency of adverse events was similar for benralizumab (76%) and placebo (80%) in the overall population. CONCLUSIONS MIRACLE data reinforces the efficacy and safety of benralizumab for severe eosinophilic asthma in an Asian population, consistent with the global Phase 3 results.

Abstract
OBJECTIVES The midpalatal suture acts as the growth centre of the maxilla. Colony-stimulating factor 1 receptor (CSF1R) is essential for osteoclastogenesis. Deletion of CSF1R, and its ligand, results in significant craniofacial phenotypes but has not been studied in detail in the midpalatal suture. MATERIALS AND METHODS Pregnant ICR mice were treated with the CSF1R inhibitor PLX5622 at embryo Day 14.5 (E14.5) to E17.5. Pups at E18.5, postnatal Day 3 (P3) and P7 were collected for skeletal and histological staining. Osteoclasts were labelled using TRAP staining. PHH3 and TUNEL were employed to detect cell proliferation and apoptosis. Sox9, Ihh, and Col10a1 and Runx2, Col1a1, and DMP1 were used to detect chondrogenic differentiation and osteogenic differentiation, respectively. CD31, MMP9 and CTSK were utilized to assess vascular invasion and osteoclast secretion enzymes, respectively. RESULTS Embryonic inhibition of CSF1R resulted in a depletion of TRAP-positive cells and an enlarged cartilage zone of the midpalatal suture of postnatal mice. Compared to those in the control group, Sox9, Ihh, Col10a1, Runx2 and Col1a1 were upregulated, whereas TUNEL and DMP1 were decreased in this zone. In the trabecular region, Col10a1 was upregulated, while TUNEL, Col1a1 and DMP1 were downregulated. Moreover, the expression of MMP9, CTSK and CD31 was decreased, and invasion into the cartilage zone was delayed. CONCLUSIONS Embryonic inhibition of CSF1R led to an abnormally enlarged cartilaginous zone in the midpalatal suture, potentially due to delayed endochondral ossification caused by the depletion of osteoclasts. Additionally, we established a novel model of midpalatal suture dysplasia, offering prospects for future research.

Abstract
Interferon regulatory factor 5 (IRF5) is a critical transcription factor in the toll-like receptor signaling pathway. It is associated with autoimmune disorders, such as rheumatoid arthritis, systemic lupus erythematosus, and inflammatory bowel disease. However, the relationship between the functional single nucleotide polymorphisms (SNPs) of IRF5 and its mRNA expression level in patients with neuromyelitis optica spectrum disorder remains unclear. The present study aimed to investigate the relationship between polymorphisms and mRNA expression levels of the IRF5 gene with the incidence of neuromyelitis optica spectrum disorder (NMOSD) in northern Chinese Han people. Two loci of the IRF5 gene (rs2004640 and rs2280714) of 164 patients with NMOSD and 269 healthy subjects were genotyped using the multiple SNaPshot technique. The frequencies of alleles, genotypes, and haplotypes were compared. Stratified analysis was performed according to age, sex, AQP4 status, onset age, and Expanded Disability Status Scale (EDSS) score. The IRF5 mRNA levels in peripheral blood mononuclear cells (PBMCs) of 64 NMOSD patients (32 patients in the acute stage and 32 patients in the remission stage) and 35 healthy subjects were detected by real-time PCR. The association of SNP polymorphisms with the mRNA expression level was determined by nonparametric tests. Allele and genotype frequency distributions of rs2004640 showed significant differences between both groups. Compared to healthy controls, the frequency of rs2004640 T allele markedly increased in patients (OR = 1.51, 95% CI = 1.09-2.08, P = 0.005). Minor allele T and GT genotype of rs2004640 that significantly increases the risk of NMOSD were discovered using genetic inheritance models (codominant, dominant, and overdominant) and haplotype analyses. Subsequent haplotype analyses revealed that the major haplotype "T-A" containing the risk alleles (the SNP sequence of the alleles was rs2004640 and rs2280714) had adverse effects on NMOSD. Based on the stratification analysis according to the EDSS score, the GT genotype frequency in the EDSS ≥ 4 group (38.2%) was markedly lower than that in the EDSS < 4 group (61.8%) (OR = 0.32, 95% CI = 0.15-0.68, P = 0.0054), with a significant difference. The IRF5 mRNA expression level was increased in NMOSD patients compared to that in normal subjects. IRF5 gene polymorphisms may be tightly associated with the genesis and progression of NMOSD in northern Chinese Han people. IRF5 mRNA expression was increased in patients with NMOSD and significantly increased in patients with acute phase. Perhaps IRF5 expression levels can be used as a predictor of disease activity in the future.

Abstract
AIMS To assess the global burden and economic inequalities in the distribution of blindness and vision loss between 1990 and 2019. METHODS A secondary analysis of the Global Burden of Diseases, Injuries and Risk Factors Study (GBD) 2019. Data for disability-adjusted life-years (DALYs) due to blindness and vision loss were extracted from the GBD 2019. Data for gross domestic product per capita were extracted from the World Bank database. Slope index of inequality (SII) and concentration index were computed to assess absolute and relative cross-national health inequality, respectively. RESULTS Countries with high, high-middle, middle, low-middle and low Socio-demographic Index (SDI) had decline of age-standardised DALY rate of 4.3%, 5.2%, 16.0%, 21.4% and 11.30% from 1990 to 2019, respectively. The poorest 50% of world citizens bore 59.0% and 66.2% of the burden of blindness and vision loss in 1990 and 2019, respectively. The absolute cross-national inequality (SII) fell from -303.5 (95% CI -370.8 to -236.2) in 1990 to -256.0 (95% CI -288.1 to -223.8) in 2019. The relative inequality (concentration index) for global blindness and vision loss remained essentially constant between 1991 (-0.197, 95% CI -0.234 to -0.160) and 2019 (-0.193, 95% CI -0.216 to -0.169). CONCLUSION Though countries with middle and low-middle SDI were the most successful in decreasing burden of blindness and vision loss, a high level of cross-national health inequality persisted over the past three decades. More attention must be paid to the elimination of avoidable blindness and vision loss in low-income and middle-income countries.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The study of male reproductive aging and its associated concerns holds significant importance within the realm of health issues affecting the elderly population. Wubi Shanyao Pills (WSP), a traditional Chinese patent medicine originating from the Tang Dynasty, has been recognized for its ability to enhance male sexual functions while also tonifying the kidney and spleen. Nevertheless, the precise effects and underlying mechanisms through which WSP ameliorates the decline in reproductive function among aging men remain uncertain. AIM OF THE STUDY This study elucidated the distinctive impacts of WSP on ameliorating the decline in reproductive function caused by natural aging, as well as its underlying mechanisms. MATERIALS AND METHODS Initially, male mice at the age of 15 months were administered WSP orally at doses of 0.375, 0.75, and 1.50 g/kg per day for a duration of 8 consecutive weeks. The impact of WSP on age-related manifestations in naturally aging mice was assessed based on their behavioral performance. The renal function of the mice was evaluated by measuring serum biochemical indicators, including Creatinine (CR), Uric acid (UA), and Blood urea nitrogen (BUN). Additionally, Superoxide dismutase (SOD) and Malonaldehyde (MDA) levels in renal tissue were determined using applied chemistry methods. Then assessed the levels of Nitric oxide (NO), Total nitric oxide synthase (T-NOS), Guanosine cyclase (GC), and Cyclic guanosine monophosphate (cGMP) in the penile tissue, as well as the expression of Endothelial nitric oxide synthase (eNOS) and Guanylate Cyclase Activator (GUCA) protein, in order to investigate the erectile function of the penis. Additionally, the quality of epididymal sperm was examined using an electron microscope. Furthermore, the serum sex hormone level and related protein expression were determined through the utilization of enzyme-linked immunosorbent assay and immunohistochemistry techniques. Pathological alterations and the ultrastructure of the testis were investigated using hematoxylin-eosin staining and transmission electron microscopy. Subsequently, the apoptosis of spermatogenic cells in the testes was assessed employing TUNEL, immunofluorescence, western blotting, and quantitative real-time polymerase chain reaction. RESULTS The administration of WSP has been found to enhance the behavioral performance and sexual behavior in aged mice. It's also could increase in serum levels of CR, UA, and BUN, as well as the elevation of SOD activity in kidney tissue, which subsequently leads to a reduction in MDA levels and an improvement in the structural damage caused by aging in the kidney tissue. Consequently, the renal function is enhanced. Additionally, WSP has been observed to elevate the levels of NO, T-NOS, GC, and cGMP in penile tissue, along with an increase in eNOS and GUCA protein expression, indicating an improvement in penile erectile function. The administration of WSP resulted in a decrease in the occurrence of programmed cell death in testicular germ cells, leading to an enhancement in sperm quality and the overall function of testicular spermatogenesis. This improvement can be attributed to the modulation of hormone levels and the regulation of SIRT1/3, p53, FOXO3, Bax, and Caspase-3 expression. CONCLUSION Collectively, our findings indicate that the administration of WSP has the potential to impede the occurrence of programmed cell death in testicular cells by modulating the expression of SIRT1/3 and subsequent genes associated with apoptosis. Consequently, this regulatory mechanism facilitates the proliferation of testicular cells and sustains the spermatogenic function of the testes. Consequently, by modulating the levels of sexual hormones in naturally aging mice, WSP ultimately enhances the quality of sperm and reproductive function. Concurrently, it also ameliorates age-related behavioral changes, renal function, and erectile function.

Abstract
Disseminated Cryptococcosis infection typically occurs in immunocompromised patients, often manifested as pneumonia or meningoencephalitis. Cases with involvement of either prostate or adrenal glands are less frequent. We describe a case of an immunocompromised 62-year-old man with new-found Idiopathic CD4 + T lymphocytopenia who presented with urinary irritation symptoms followed by headache. The patient was finally diagnosed as disseminated cryptococcosis of prostate, adrenal gland involvement with the help of combining histopathology of formalin-fixed, paraffin-embedded tissue with metagenomic next-generation sequencing technique to identify C neoformans sensu stricto in prostate, adrenal gland tissues. Clinicians should be aware of atypical presentations of cryptococcal disease. In this case of cryptococcosis in immunocompromised patients, we find that cryptococcosis can affect varied organs simultaneously and should be considered in the differential of infectious diseases. And mNGS technology helps to confirm the diagnosis.

Abstract
BACKGROUND Early-onset pharyngeal airway collapse (PAC) in infants, which presents with onset within 6-months old is relatively rare. This disease has not been given enough attention in clinic. The aim of this study was to explore the clinical features, endoscopic findings and outcomes of early-onset PAC in infants. METHODS The children of PAC with onset within 6-months old were included. A retrospective study was conducted. RESULTS (1) Total 26 cases were included. The age of onset was neonatal period in 20 cases, 1 to 3-months old in 5 cases, and 4 to 6-months old in 1 case. (2) The main clinical manifestations were noisy breathing (26/26), suprasternal retraction (18/26), snoring (14/26) and hypoxic episode (13/26). (3) Based on the endoscopic findings, collapse at the retropalatal level was most common (24/26). (4) Twelve cases underwent pharyngolaryngeal CT examination, which revealed abnormal findings in 7 cases. (5) Fifteen cases were accompanied with the other airway malformations. (6) In the group with comorbidities of cerebral impairment or craniofacial abnormalities, 1 case was lost to follow up, 4 cases died, and 10 cases survived, in which 9 cases had neurodevelopmental disorders. In the group without comorbidities, 2 cases were lost to follow up, 9 cases survived, in which 1 case had neurodevelopmental disorders. The incidence of poor prognosis including death and neurodevelopmental disorders was significantly higher in the group with comorbidities than that without comorbidities (P<0.01). (7) An symptomatic improvement of PAC was found in the majority of the survived cases (18/19) with age. CONCLUSIONS Early-onset PAC in infants usually exhibits varying degrees of relief with age, whereas the cases with comorbidities had a poor prognosis.

Abstract
PURPOSE To compare donor-site morbidity for alveolar bone grafting results following cartilage-preserving outer and inner cortico-cancellous iliac crest (OCIC and ICIC) bone block grafting in children. MATERIALS AND METHODS Patients were randomly divided into two groups and prospectively reviewed. In the OCIC and ICIC groups, cortico-cancellous bone blocks were harvested at outer and inner iliac crest respectively. Patient characteristics and surgical parameters were compared; pain intensity and duration, lateral femoral cutaneous nerve (LFCN) injury, gait disturbance, scar and contour satisfaction were analysed postoperatively. RESULTS Forty-nine consecutive patients (OCIC, 24; ICIC, 25) were included. There were no significant differences in patient characteristics or donor-site surgical parameters. The mean pain score on the first post-operative day was significantly lower in the OCIC group (3.75±1.70) than in the ICIC group (5.20±2.08) (p=0.012). The pain duration was similar in the two groups (median: 5 days). Temporary LFCN injury only occurred in 3 patients in the ICIC group. Postoperatively, the duck and circle gaits were observed in the OCIC and ICIC groups, respectively. There were no significant differences in the claudication duration, scar and contour satisfaction between the groups. CONCLUSION OCIC bone graft harvesting is marginally advantageous in children due to less early postoperative donor-site pain and a lower risk of nerve damage.

Abstract
Hemoporfin-mediated photodynamic therapy (HMME-PDT) is commonly used in the treatment of port-wine stains (PWS). However, the influential factors for the efficacy of the treatment are not well defined. This study intends to observe the influential factors for the efficacy of HMME-PDT in the treatment of port-wine stains (PWS). A total of 551 patients with PWS of head and neck was enrolled in this retrospective study. Further screening the patients of facial PWS, 484 patients were chosen. Patients were treated with HMME-PDT. All patients received 1~3 sessions of treatment with 2~3-month intervals. We photographed the lesions before each session and 2~3 months after the last session. Ages, sessions, lesion subtypes, and previous treatment history were related to the response of HMME-PDT (P =0.032, P<0.001, P=0.012, P=0.003 respectively). Treatment sessions were the independent factor correlated with efficacy after 3 sessions of treatment. Patients with no treatment history targeting PWS showed higher efficacy than those were treated with laser or other photodynamic treatment (P<0.05). The efficacy was higher by increasing the sessions of treatment. The efficacy was higher for lesion on maxillary prominence area and mandibular prominence area that on frontonasal prominence area and optic vesicle area (P<0.05). HMME-PDT is an effective in the treatment of PWS. Patients received no previous treatment for PWS, total treatment sessions and lesion on maxillary prominence area and mandibular prominence area are positive factors.

Abstract
OBJECTIVE To investigate the changes in gray matter volume in depressive-like mice and explore the possible mechanism. METHODS Twenty-four 6-week-old C57 mice were randomized equally into control group and model group, and the mice in the model group were subjected to chronic unpredictable mild stimulation (CUMS) for 35 days. Magnetic resonance imaging was performed to examine structural changes of the grey matter volume in depressive-like mice. The expression of brain-derived neurotrophic factor (BDNF) in the grey matter of the mice was detected using Western blotting and immunofluorescence staining. RESULTS Compared with the control mice, the mice with CUMS showed significantly decreased central walking distance in the open field test (P < 0.05) and increased immobile time in forced swimming test (P < 0.05). Magnetic resonance imaging showed that the volume of the frontal cortex was significantly decreased in CUMS mice (P < 0.001, when the mass level was greater than or equal to 10 756, the FDRc was corrected with P=0.05). Western blotting showed that the expression of mature BDNF in the frontal cortex was significantly decreased in CUMS mice (P < 0.05), and its expression began to decrease after the exposure to CUMS as shown by immunofluorescence staining. The volume of different clusters obtained by voxel-based morphometry (VBM) analysis was correlated with the expression level of mature BDNF detected by Western blotting (P < 0.05). CONCLUSION The decrease of frontal cortex volume after CUMS is related with the reduction of mature BDNF expression in the frontal cortex.

Abstract
The basic helix-loop-helix (bHLH) transcription factors (TFs) gene family is an important gene family in plants, and participates in regulation of plant apical meristem growth, metabolic regulation and stress resistance. However, its characteristics and potential functions have not been studied in chestnut (Castanea mollissima), an important nut with high ecological and economic value. In the present study, 94 CmbHLHs were identified in chestnut genome, of which 88 were unevenly distributed on chromosomes, and other six were located on five unanchored scaffolds. Almost all CmbHLH proteins were predicted in the nucleus, and subcellular localization demonstrated the correctness of the above predictions. Based on the phylogenetic analysis, all of the CmbHLH genes were divided into 19 subgroups with distinct features. Abundant cis-acting regulatory elements related to endosperm expression, meristem expression, and responses to gibberellin (GA) and auxin were identified in the upstream sequences of CmbHLH genes. This indicates that these genes may have potential functions in the morphogenesis of chestnut. Comparative genome analysis showed that dispersed duplication was the main driving force for the expansion of the CmbHLH gene family inferred to have evolved through purifying selection. Transcriptome analysis and qRT-PCR experiments showed that the expression patterns of CmbHLHs were different in different chestnut tissues, and revealed some members may have potential functions in chestnut buds, nuts, fertile/abortive ovules development. The results from this study will be helpful to understand the characteristics and potential functions of the bHLH gene family in chestnut.

Abstract
A biopsy of gastrocnemius muscle from a patient with mitochondrial encephalomyopathy with lactic acidosis and stroke-like episodes (MELAS) syndrome was studied histologically in semithin sections stained by hematoxylin-and-eosin (H&E) and toluidine blue, and ultrathin sections by transmission electron microscopy (TEM). H&E stain demonstrated typical ragged-red fibers (RRFs) and affected fibers in fascicles. Toluidine-blue stain showed an irregular meshwork in the center of RRFs. TEM demonstrated damaged myofibrils and variations in mitochondrial structure in RRFs and affected fibers. Dense mitochondria were compacted with cristae and pleomorphic electron-dense inclusions. Lucent mitochondria included paracrystalline inclusions with a parking lot appearance. At high magnification, the paracrystalline inclusions were composed of plates that paralleled and connected with mitochondrial cristae. These observations indicated that electron-dense granular and paracrystalline inclusions resulted from cristal degeneration and overlapping in mitochondria in MELAS syndrome.

Abstract
BACKGROUND Previous studies have shown that the Kyoto classification of gastritis can accurately predict H. pylori infection status on conventional gastroscopy. The aim of this study was to test whether the Kyoto classification of gastritis applies well to magnetic controlled capsule endoscopy (MCCE). METHODS We consecutively recruited 227 participants who underwent both MCCE and urea breath tests (UBTs). Two physicians who were blinded to the UBT results independently made the diagnosis of H. pylori infection status according to 10 findings listed in the Kyoto classification of gastritis after reviewing MCCE images. We also developed 2 predictive models to assess H. pylori infection status by combining these 10 findings. RESULTS The MCCE's overall diagnostic accuracy for H. pylori infection status was 80.2%. The sensitivity, specificity and diagnostic odds ratio (DOR) for current infection were 89.4%, 90.1% and 77.1, respectively. Major specific findings were mucosal swelling and spotty redness for current infection, regular arrangement of collecting venules (RAC), streak redness, fundic gland polyp (FGP) for noninfection, and map-like redness for past-infection. In the two prediction models, the area under the curve (AUC) values for predicting noninfection and current infection were 84.7 and 84.9, respectively. CONCLUSIONS The Kyoto classification of gastritis applied well to MCCE. H. pylori infection status could be accurately assessed on MCCE according to the Kyoto classification of gastritis.

Abstract
AIMS To explore the prevalence and risk factors for myopia and uncorrected myopia in schoolchildren in southern China. METHODS The government-led Shantou Myopia Study was conducted from September 2020 to June 2021. Non-cycloplegic refraction was performed. Uncorrected visual acuity (UCVA) was measured along with presenting visual acuity if participants wore spectacles. Spherical equivalent refraction (SER) is defined as the spherical dioptres added to half of the cylindrical dioptres. Myopia is defined as SER <-0.50 dioptre with UCVA of <20/20 in at least one eye. RESULTS This study enrolled 724 828 schoolchildren (77.8% of all schoolchildren in Shantou) from 901 schools. Data from 721 032 schoolchildren (99.5%) were analysed (mean age 11.53±3.13 years, 6-20 years, 373 230 boys and 347 802 girls). Among them, 373 459 (51.8%) had myopia: 37.1% of 465 696 children in primary schools, 75.4% of 170 164 children in junior high schools and 84.8% of 85 172 children in senior high schools. The prevalence of myopia increases non-linearly with age. Older age, female and urban living environment were independently associated with myopia prevalence and myopic SER. Among the 373 459 children with myopia, 60.0% had no refractive correction: 74.9%, 53.9% and 35.5% in primary, junior high and senior high schools, respectively. CONCLUSION The overall prevalence of myopia among schoolchildren in Shantou was 51.8%, higher than the national average in China. The proportion of uncorrected myopia is high, especially in primary schools. Our results indicate the need for public education on eye care among schoolchildren even in a municipal city.

Abstract
OBJECTIVE Lycium barbarum polysaccharide (LBP) is the efficient primary compound of Lycium barbarum and has been shown to alleviate hyperglycemia-aggravated cerebral ischemia/reperfusion (I/R) injury. However, the cerebrovascular changes related to diabetes mellitus (DM) and the potential cerebrovascular protective effects of LBP are still unknown. This study aimed to explore the cerebrovascular protective functions of LBP on cerebral I/R injury in diabetic rats and its potential mechanisms. MATERIALS AND METHODS Sprague Dawley (SD) rats were separated into three groups: the normoglycemic (NG), diabetic hyperglycemic (HG), and HG + LBP (50 mg/kg) treatment groups. A 30 min transient middle cerebral artery occlusion (tMCAO) with 24 h reperfusion was established. The neurological deficits, cerebral water content, infarct volume, and cerebrovascular permeability were assessed to evaluate the extent of cerebral injury. Histopathological alterations were assessed by hematoxylin and eosin, Nissl, immunohistochemical, and terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling staining. A transmission electron microscope was used to detect ultrastructural alterations, and a western blot was used to examine protein expression. RESULTS The HG rats exhibited a significant increase in neurological deficits, cerebral water content, infarct volume, cerebrovascular permeability, neural cell death, and apoptosis compared with the NG rats, and the LBP treatment alleviated these effects. Cerebrovascular structure analysis showed that the cross-sectional area (CSA) and wall thickness were remarkably altered in the HG rats compared with the NG rats. The LBP treatment protected the cerebrovascular structure and vasoreactivity by decreasing the wall thickness and increasing the CSA, α-smooth muscle actin, and endothelial nitric oxide synthase expression of cerebral vessels. CONCLUSIONS The intake of LBP benefits the cerebrovascular structure and vasoreactivity in diabetic rats. Our research provides a possible new strategy for treating stroke in patients with DM.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Diabetic foot ulcers mainly refer to people who are initially diabetic and do not have peripheral neuropathy or peripheral vascular disease, but have developed foot infection, septicemia, and ulceration. Diabetic trauma disease is characterized by high sugar and very slow wound healing, which is the reason why some patients with severe diabetic trauma require amputation. Prolonged hyperglycemia can lead to changes in bodily functions and endocrine changes, which can lead to permeability damage of epidermal tissue structure, microvascular damage and, in more severe cases, nerve damage, which are also the main causes of diabetic trauma. Small molecule peptides have various biological activities, such as: lowering blood pressure, antibacterial and wound healing activities, etc. It is a drug recorded in classical Chinese medicine, it is safer to use natural active peptides to treat wounds compared to the listed drugs, and there are no side effects in its use.The wound healing effect of Wuguchong dry product has been confirmed but the mechanism is still unclear, whether it is related to the small molecule active peptides contained in it remains to be studied. AIM OF STUDY Objective To investigate the potential mechanism of the peptide compounds of Wuguchong (PCW) on diabetic wound healing and the relevant targets in the pathway associated with the treatment of diabetic ulcers using a systematic pharmacological and pharmacological experimental validation approach. METHODS 1) PCW was prepared by enzymatic digestion of TCMW and analyzed by UHPLC-Q-TOF-MS. 2) Further screening of the active chemical components of PCW using PubChem, Swiss Target Prediction data. 3) Prediction of its targets using Drug Bank, CTD, and Genecards databases. 4) Construct protein/gene interactions network diagrams for PCWs acting by using Cytoscape 3.7.0 software. 5) GO and KEGG analysis of PCW targets were performed by David database. 6) Validated by AO/EB staining, scratching and in vitro tube formation methods. 7) Explored the mechanism of PCW to promote diabetic wound healing by protein blotting and immunohistochemical detection of relevant protein expression. RESULTS and finally: 1) After the above screening, 81 active ingredients of PCW and 94 targets acting on diabetic ulcers were obtained. 2) 30 biological processes, 30 cellular compositions and 30 molecular functions were obtained by GO analysis; 28 signaling pathways were obtained by KEGG analysis. 3) The results of AO/EB staining assay, scratch assay and in vitro tube-forming assay showed that PCW has significant pro-vascular endothelial cell proliferation and pro-angiogenic effects in vitro. CONCLUSIONS The results of this study confirmed the effect of the PCW in treating diabetic ulcers to a certain extent, and further revealed its mechanism of action in depth, which provides a new reference for the next step of Chinese medicine in treating diabetic ulcers.

Abstract
Respiratory pandemics, such as COVID19, may be transmitted by several modes. The present work focuses on the transmission through small droplets released by people from their mouth by breathing, speaking, coughing, sneering, and possibly aspirated by other people around through their respiration. An analysis of droplet evolution in simplified situations shows that the droplets reach very quickly a quasi-equilibrium temperature before encompassing an isothermal evaporation process. The removal of droplets from suspension is thus piloted by balance between evaporation and sedimentation. It is shown that ambient relative humidity is a major factor influencing the lifetime of droplets and the distance they may travel. As a consequence, and independently of any other health consideration linked to ambient humidity, it is seen that a dry air is a favourable factor for limiting risk of contamination from COVID19. Further investigation is made using computational fluid dynamics (CFD) in a classroom geometry. Several ventilation strategies are investigated: classical regulatory mechanical ventilation, open window natural ventilation and displacement natural ventilation. Ventilation has several effects which influence contamination risk: by introducing fresh air, it reduces droplet concentration; humidity released by human occupants is also limited. However, these effects are not uniform in space, and depend on ventilation strategy. Application of a dose-effect model calibrated for COVID19 to CFD results allows to estimate contamination risk. It is shown that contamination risk is higher for regulatory mechanical ventilation, and may be reduced, using natural ventilation in the absence of wind, by a factor 2.3 to nearly 3 when the teacher is sick, and by a factor 6 to 500 when a student is sick. In the presence of wind, the reduction factor is as high as 13 when the teacher is sick and 17 when a student is sick.

Abstract
BACKGROUND Entrustable professional activities (EPAs) were first introduced by Olle ten Cate in 2005. Since then, hundreds of applications in medical research have been reported worldwide. However, few studies discuss the use of EPAs for residency training in pediatric intensive care medicine. We conducted a pilot study of EPA for pediatric intensive care medicine to evaluate the use of EPAs in this subspecialty. MATERIALS AND METHODS A cross-sectional study was implemented in pediatric intensive care medicine standardized residency training at the Qilu Hospital of Shandong University. An electronic survey assessing EPA performance using eight scales composed of 15 categories were distributed among residents and directors. RESULTS A total of 217 director-assessment and 44 residents' self-assessment questionnaires were collected, both demonstrating a rising trend in scores across postgraduate years. There were significant differences in PGY1-vs.-PGY2 and PGY1-vs.-PGY3 director-assessment scores, while there were no differences in PGY2-vs.-PGY3 scores. PGY had a significant effect on the score of each EPA, while position significantly affected the scores of all EPAs except for EPA1 (Admit a patient) and EPA2 (Select and interpret auxiliary examinations). Gender only significantly affected the scores of EPA6 (Report a case), EPA12 (Perform health education), and EPA13 (Inform bad news). CONCLUSION This study indicates that EPA assessments have a certain discriminating capability among different PGYs in Chinese standardized residency training in pediatric intensive care medicine. Postgraduate year, gender, and resident position affected EPA scores to a certain extent. Given the inconsistency between resident-assessed and director-assessed scores, an improved feedback program is needed in the future.

Abstract
Lithium disilicate (LD) glass-ceramics with a stoichiometric composition were ion-exchanged in pure NaNO3 or mixed NaNO3 + KNO3 molten salt baths below the glass transition temperature (Tg). The microstructures, surface morphologies, mechanical properties and bioactivities of the ion-exchanged glass-ceramics were studied in detail. It was found that the strength and toughness of LD glass-ceramic could be enhanced from 175 MPa to 0.96 MPa m1/2 before ion-exchange to 546 MPa and 4.31 MPa m1/2 respectively under a lowered ion-exchange temperature because the less stress relaxation. In addition, a gradient of Na+ rich layer in the surface of glass-ceramic was induced by Li+/Na+ exchange, which could be beneficial to the formation of HA (Hydroxyapatite) with nano-size porous after soaking in SBF (Simulated Body Fluid) solution and exhibited better bioactivity compared with the original LD glass-ceramic. The results might provide a reference for the strengthening and biological activation of LD glass-ceramics in bone restoration applications.

Abstract
Objective: To report the risk factors, clinical characteristics and treatment courses of pulmonary mucormycosis after lung transplantation(LT). Methods: We included 3 cases with pulmonary mucormycosis after LT from March 2017 to July 2020 in the centre for lung transplantation of China-Japan Friendship Hospital. Twelve cases from Chinese and English literature from China National Knowledge Infrastructure (CNKI), China Biomedical Literature Service System and Pubmed Database from March 1980 to July 2020 were added. The risk factors, clinical characteristics and treatment courses of all cases were summarized and analyzed. Results: Pulmonary mucormycosis occurred in 1.06% (3/284) in our centre. A total of 15 cases with 12 cases from literature included 10 males and 5 females with a mean age of(47±20)years. Thirteen cases occurred after LT, and 2 cases occurred after heart-lung transplantation (HLT). Nine probable cases were diagnosed by positive isolation of the pathogen from bronchoalveolar lavage fluid or sputum. Three proven cases were diagnosed by transbronchial lung biopsy. Meanwhile, the other 3 proven cases diagnosed by CT-guided percutaneous lung biopsy, autopsy and surgical operation respectively. Ten cases (66.7%) were diagnosed with pulmonary mucormycosis within 90 days after lung transplantation. The mortality was as high as 46.67% (7/15), but if it occurred within 90 days, the mortality reached 70% (7/10). The average interval between transplantation and positive isolation of the pathogen was 112.3 (5-378) days. Conclusions: The clinical and radiographic features of pulmonary mucormycosis after LT were nonspecific. It had a high mortality, especially in those occurred within 90 days after LT. The combination of antifungal therapy and surgical resection may contribute to a better outcome of the disease.

Abstract
BACKGROUND Adrenocortical carcinoma is a rare, isolated malignancy. CASE A 13-year-old girl presented with secondary amenorrhea, hirsutism, and hypertension. Her clinical manifestations were interpreted as polycystic ovary syndrome and hyperinsulinemia. The rapid progression of this pubertal girl's virilization should have, but did not draw clinical attention to her malignancy. Because her condition worsened, she ultimately was transferred to our hospital because of an abdominal mass. She was diagnosed with a very large adrenal cortical carcinoma with pulmonary metastasis. The child was in the advanced stage and presented adrenal crisis after chemotherapy and mitotane treatment. SUMMARY AND CONCLUSION Rapidly progressive masculinization, with a marked increase in adrenal-derived androgens, might indicate rare adrenal neoplasms.

Abstract
The environmental problem of Microplastics (MPs) pollution poses a great threat to human and animal health, which has attracted global attention. The physiological integrity of skeletal muscle is extremely important for the survival of animals. Here, we investigated the effect of two size polystyrene microplastics (PS-MPs, 1-10 µm and 50-100 µm) on the growth of anterior tibial (TA) muscle and repair after injury in mice. Results showed that the regeneration of skeletal muscle was delayed by PS-MPs exposure and was negatively correlated with particle size. H&E staining and Oil red O staining showed that PS-MPs exposure reduced the average cross-sectional area (CSA) and diameter of the muscle fibers, increased lipid deposition. Further mechanistic research displayed that though PS-MPs treatment did not affect cell viability of myoblast, it aggravated intracellular ROS generation and oxidative stress, inhibited myogenic differentiation by decreasing the phosphorylation of p38 MAPK, and promote adipogenic differentiation by increasing the expression of NF-κB, which could be alleviated by NAC. In brief, our data demonstrated that the ROS overproduction caused by PS-MPs disturbed the regeneration of skeletal muscle and directed the fate of satellite cells in mice.

Abstract
To clarify the characteristics and origin of the cellular components in atherosclerosis, carotid atherosclerotic plaques (CAPs) of four patients were studied by light microscopy using hematoxylin-eosin, Congo red and alpha-smooth-muscle actin stains, and by transmission electron microscopy of different regions of CAPs. By light microscopy, CAPs were composed of 1) a fibrous cap; 2) an atherosclerotic core presenting focal fibrosis, neovascularization, hemorrhage, necrosis, chondrification and ossification; and 3) a basal band composed of a hyperplasic pseudo-media and affected tunica media. Ultrastructurally, the CAPs contained a diversity of cells including fibroblasts, myofibroblasts, osteochondrocytes, vascular smooth-muscle cells, foam cells and other myoid cells characterized by varied features of the above mentioned cells. The results indicated that CAPs were derived from a proliferation of multipotential mesenchymal stem cells, leading to the presence of degenerated foam cells and lipid-laden cells.

Abstract
With aging and pathology, cells of the nucleus pulposus (NP) de-differentiate towards a fibroblast-like phenotype, a change that contributes to degeneration of the intervertebral disc (IVD). Laminin isoforms are a component of the NP extracellular matrix during development but largely disappear in the adult NP tissue. Exposing human adult NP cells to hydrogels made from PEGylated-laminin-111 (PEGLM) has been shown to regulate NP cell behaviors and promote cells to assume a biosynthetically active state with gene/protein expression and morphology consistent with those observed in juvenile NP cells. However, the mechanism regulating this effect has remained unknown. In the present study, the integrin subunits that promote adult degenerative NP cell interactions with laminin-111 are identified by performing integrin blocking studies along with assays of intracellular signaling and cell phenotype. The findings indicate that integrin α3 is a primary regulator of cell attachment to laminin and is associated with phosphorylation of signaling molecules downstream of integrin engagement (ERK 1/2 and GSK3β). Sustained effects of blocking integrin α3 were also demonstrated including decreased expression of phenotypic markers, reduced biosynthesis, and altered cytoskeletal organization. Furthermore, blocking both integrin α3 and additional integrin subunits elicited changes in cell clustering, but did not alter the phenotype of single cells. These findings reveal that integrin- mediated interactions through integrin α3 are critical in the process by which NP cells sense and alter phenotype in response to culture upon laminin and further suggest that targeting integrin α3 has potential for reversing or slowing degenerative changes to the NP cell.

Abstract
OBJECTIVE To investigate the relationship between the meniscal defect area and OA progression and explore the effect and mechanism of SMSCs cell therapy in knee osteoarthritis (OA) rat model. MATERIALS AND METHODS For animal experiments, knee osteoarthritis (OA) model was constructed in Sprague Dawley (SD) rats by removing the medial meniscus of the right knee. Synovial mesenchymal stem cells (SMSCs) were engrafted by injecting into the right knee cavity. For in vitro experiments, CCK-8 assay was performed to evaluate the proliferation and differentiation of BMSCs and ATDC5 cells after co-cultured with SMSCs. qRT-PCR analysis was performed to detect the expressions of chondrogenic genes in BMSCs and ATDC5 cells after co-cultured with SMSCs. Western blot analysis was conducted to detect the phosphorylations of c-Jun N-terminal kinase (JNK) and extracellular regulated protein kinases (ERK) in MAPK signaling of BMSCs and ATDC5 cells. Enzyme-linked immunosorbent assay (ELISA) was performed to detect the serum levels of interleukin (IL)-1β, IL-1β, IL-6, IL-18 and C-reactive protein (CRP). RESULTS Results showed that meniscus damaged area is positively correlated to serum inflammatory factor levels. In vitro study showed that the proliferation and differentiation of BMSCs and ATDC5 cells were promoted after co-cultured with SMSCs. By co-culturing with SMSCs, the MAPK signaling pathway was activated and the expression of chondrogenic markers such as aggrecan (acan), SRY-related high mobility group-box gene 9 (sox9) and Type II collagen a1 (col2a1), was up-regulated both in BMSCs and ATDC5 cells. In vivo study showed SMSCs cell therapy significantly decreased serum inflammatory factor levels and protected cartilage by upregulating the expression of chondrogenic genes of meniscus chondrocytes derived from OA rats. CONCLUSIONS For the first time, we found the positive correlation between meniscal defect area and OA progression and demonstrated the effect and mechanism of SMSCs cell therapy in knee osteoarthritis (OA) treatment.

Abstract
The present study focused on the characteristics of the vaginal microbiomes in prepubertal girls with and without vulvovaginitis. We collected 24 vaginal samples and 16 fecal samples from 10 girls aged 3–9 years with vulvovaginitis and 16 healthy girls of the same age. The samples were divided into three groups: fecal swabs from healthy controls (HF), vaginal swabs from healthy controls (HVS), and vaginal swabs from girls with vulvovaginitis (VVS). Sequencing of the V3–V4 region of the 16S rDNA gene was performed with the NovaSeq PE250 platform to reveal the vaginal microbial community structure in healthy prepubertal girls and vulvovaginitis-associated microbiota. The intestinal microbiomes of healthy children were also analyzed for comparison. This study revealed that the healthy vaginal tract in prepubertal girls was dominated by Prevotella, Porphyromonas, Ezakiella, and Peptoniphilus species, with a high diversity of microbiota. The vulvovaginitis-associated microbiota were dominated by Streptococcus, Prevotella, Haemophilus, and Granulicatella, with lower diversity than that in healthy girls. Furthermore, the compositions of the vaginal and intestinal microbiomes were completely different. ANOSIM, MRPP, Adonis, and AMOVA were used to analyze the beta diversity, and the results showed that there were significant differences in the microbial communities among the three groups. Lactobacillus deficiency and high bacterial diversity were characteristics of the vaginal microbiome in healthy prepubertal girls; this is inconsistent with that in reproductive-age women. The vulvovaginitis-associated vaginal microbiota differed dramatically from normal microbiota, and the main causative agents were not fecal in origin.

Abstract
Objective: To evaluate the accuracy of different intraocular lens (IOL) power calculation formulas and develop prognostic nomograms to predict the risk of postoperative refractive error in primary angle-closure glaucoma (PACG) patients. Methods: A total of 111 eyes with PACG underwent goniosynechialysis combined with phacoemulsification and IOL implantation were included. SRK/T, Barrett II, Hoffer Q, and Kane formulas were used to predict postoperative refraction. Prediction error (PE) and absolute predictive error (APE) produced by the four formulas were calculated and compared. An APE >0.50 D was defined as the event. Binary logistic regression analysis and prognostic nomogram models were conducted to investigate reliable predictors associated with postoperative refraction. Results: The Kane (-0.06 D) and Barrett II (-0.07 D) formulas had mean prediction error close to zero (p = 0.44, p = 0.41, respectively). The Hoffer Q and SRK/T produced significantly myopic outcomes (p = 0.003, p = 0.013, respectively). The percentage of eyes within ± 0.5 D was 49.5% (55/111), 44.1% (49/111), 43.2% (48/111), and 49.5% (54/111), for the Kane, Barrett II, Hoffer Q, and SRK/T formula, respectively. Nomogram showed that AL had the greatest impact on the refractive outcomes, indicating a shorter preoperative AL is associated with a greater probability of refractive error event. The area under the receiver operator curve (AUC) of the nomogram for the Kane, Barrett II, Hoffer Q, and SRK/T was 0.690, 0.701, 0.708, and 0.676, respectively. Conclusions: The Kane and Barrett II formulas were comparable, and they outperformed Hoffer Q and SRK/T in the total eyes with PACG receiving cataract surgery combined with goniosynechialysis. The developed nomogram models can effectively predict the occurrence of postoperative refractive error events.

Abstract
BACKGROUND biomarkers can be helpful in identifying patients who may profit by explicit treatments or evaluating the reaction to the treatment of specific disease. Finding unique biomarkers in the process of disease could help clinicians in identifying serious disease in the early stage, so as to improve prognosis. OBJECTIVE these investigations, nonetheless, have made constrained progress. Numerous infections are known to cause intense viral encephalitis (VE) in people which can cause a variable level of meningeal just as parenchymal aggravation. Initial clinical manifestations in most encephalitis are nonspecific, resembling a viral-like illness. However, with disease progression, symptoms can become quite severe and fatal, including prominent cranial hypertension, cognitive problems, cerebral hernia and respiratory failure. Forwards: the clinical and research center discoveries in huge numbers of those viral issues are to a great extent comparable and in this way increasingly explicit biomarkers for indicative and prognostic intentions are justified. These biomarkers are progressively significant in the acknowledgment and treatment of the viral central nervous system (CNS) issue. CONCLUSION Clinical manifestations have been the indicative approaches for analysis of viral encephalitis. Lots of studies have been endeavored to distinguish progressively objective laboratory-based quantitative CSF biomarkers for VE.

Abstract
OBJECTIVE Long stress-induced noncoding transcripts 5 (LSINCT5) has been reported to be upregulated in several human cancers and related to poor prognosis. However, its involvement in esophageal squamous cell carcinoma (ESCC) remains largely unknown. We aim to evaluate the expression and putative role of LSINCT5 on the progression of ESCC. MATERIALS AND METHODS LSINCT5 expression was first examined in the ESCC cell lines using RT-qPCR, and the next-generation RNA-Seq technology was employed to analyze and functionally annotate the differential gene expression before and after LSINCT5 knockdown in ESCC was made. Based on the functional annotation results, the effects of LSINCT5 knockdown on cell growth, migration, invasion, and epithelial-to-mesenchymal transition (EMT) were assessed in the ESCC cell lines. Finally, the expression and clinicopathological significance of LSINCT5 in ESCC and corresponding nontumor tissues were further explored using RT-qPCR. RESULTS The RT-qPCR results showed that LSINCT5 expression was significantly upregulated in the ESCC cell lines. The differential gene expression analysis by next-generation RNA-Seq showed that 138 genes were up-regulated, and 227 genes were downregulated after LSINCT5 was knocked down in the ECA 109 cells. In addition, the functional annotation revealed that the differentially expressed genes were mainly functionally involved in tight junctions, ECM-receptor interactions, and MAPK signaling pathway. Further in vitro studies indicated that the knockdown of LSINCT5 significantly suppressed proliferation, migration, invasion, and EMT in ESCC cells. Finally, a comparative study of paired ESCC and corresponding nontumor tissues showed that LSINCT5 was upregulated in the ESCC tissues, and the increased LSINCT5 expression was related to late clinical stages, large tumor sizes, and lymph node metastasis. CONCLUSIONS The results indicate that LSINCT5 is upregulated in ESCC and may act as an oncogene promoting the progression of ESCC.

Abstract
OBJECTIVE This study aims to investigate effects of checkpoint kinase, mediator of DNA damage checkpoint 1 (MDC1) and p53-binding protein 1 (53BP1) silencing on p53, checkpoint kinase 1 and 2 (CHK1 and CHK2), and CHK2-T68 expression. MATERIALS AND METHODS Eca109 cells were divided into untransfected Eca109, Blank-vector, MDC1-RNAi transfection, and 53BP1-RNAi transfection group. Streptavidin-peroxidase (SP) immunohistochemical assay was used to examine CHK2-T68 expression. About 4 groups were used to establish esophageal carcinoma nude-mouse models, and assigned as Eca-109 control (or Eca-109 plus 15 Gy γ-rays irradiation, Eca-109+IR), Blank-vector (or Blank-vecor+IR), 53BP1-RNAi (or 53BP1-RNAi+IR), and MDC1-RNAi group (or MDC1-RNAi+IR group) by injecting. The expression of p53, CHK1, CHK2 were evaluated using SP immunohistochemical assay. RESULTS 53BP1 and MDC1 down-regulation significantly inhibited expression of CHK2-T68 in Eca-109 cells compared to untreated group (p<0.05). There were significant differences for CHK2-T68 expressions in different time and groups (p<0.05). 53BP1 down-regulation significantly reduced p53 and enhanced CHK1 and CHK2 expression compared to that of Eca-109 control group (p<0.05) in Eca-109 cells. 53BP1 down-regulation significantly regulated CHK1, CHK2, and p53 in xenograft nude mice models exposed to γ-ray irradiation compared to that of untreated group (p<0.05). p53 was negatively correlated with CHK1 and CHK2 in xenograft nude mice models. CONCLUSIONS 53BP1 regulated the cell cycle arrest by modulating p53, CHK1, and CHK2 expression in both Eca-109 cells and xenograft nude mice models.

Abstract
BACKGROUND AND PURPOSE MR imaging is a useful and widely used evaluation for chordomas. Prior studies have classified chordomas into cell-dense type and matrix-rich type according to the ultrastructural features. However, the relationship between the MR imaging signal intensity and ultrastructural classification is unknown. We hypothesized that MR imaging signal intensity may predict both tumor ultrastructural classification and prognosis. MATERIALS AND METHODS Seventy-nine patients with skull base chordomas who underwent 95 operations were included in this retrospective single-center series. Preoperative tumor-to-pons MR imaging signal intensity ratios were calculated and designated as ratio on T1 FLAIR sequence (RT1), ratio on T2 sequence (RT2), and ratio on enhanced T1 FLAIR sequence (REN), respectively. We assessed the relationships among signal intensity ratios, ultrastructural classification, and survival. RESULTS Compared with the matrix-rich type group, the cell-dense type chordomas showed lower RT2 (cell-dense type: 1.90 ± 0.38; matrix-rich type: 2.61 ± 0.60 P < .001). The model of predicting cell-dense type based on RT2 had an area under the curve of 0.83 (95% CI, 0.75-0.92). In patients without radiation therapy, both progression-free survival (P = .003) and overall survival (P = .002) were longer in the matrix-rich type group than in the cell-dense type group. REN was a risk factor for progression-free survival (hazard ratio = 10.24; 95% CI, 1.73-60.79); RT2 was a protective factor for overall survival (hazard ratio = 0.33; 95% CI, 0.12-0.87); and REN was a risk factor for overall survival (hazard ratio = 4.76; 95% CI, 1.51-15.01). CONCLUSIONS The difference in MR imaging signal intensity in chordomas can be explained by electron microscopic features. Both signal intensity ratios and electron microscopic features may be prognostic factors.

Abstract
As a single maternally inherited locus, human mitochondrial DNA (mtDNA) is geographically arranged and plays a key role in forensic applications. Hlai population has been evidenced as the most typical and unmixed representative of the Tai-Kadai-speaking populations via genome-wide analyses. However, forensic features and maternal diversity of the complete mitogenomes in this Tai-Kadai ancestrally related population are scarce. Thus, we sequenced the complete mitogenomes in 127 Hainan Hlais and found 109 distinct haplotypes belonging to 43 terminal haplogroups resulting in the haplotype diversity of 0.9970. Our results of comprehensive population comparisons showed that Hlai islanders had a close genetic affinity with Tai-Kadai-speaking populations from Southeast Asia, which is consistent with the back-migration of Chinese Neolithic farmers into this region via the inland route. Besides, maternally genetic evidence further revealed a close genetic relationship between Tai-Kadai-speaking and Austronesian-speaking populations when only East Asian dataset was considered, which is consistent with the common origin from Yangtze rice farmers and then spread southward along the inland and coastal routes, respectively. In the reconstructed phylogenetic tree and median-joining networks, the vast majority of Hlais were clustered in exclusive clades, which demonstrated that Hlai people probably had undergone founder effect or genetic bottleneck in their history, and remained genetically isolated for a long time. Collectively, Hainan Hlai did not exhibit detectable maternal gene flow from surrounding or incoming populations. Mitogenome information generated in this study is a contribution in mitigating the underrepresentation of Chinese data in forensic mitogenetics and will assist geography-, metapopulation-, as well as phylogeny-based queries.

Abstract
Aim: Methotrexate (Mtx) is prescribed to reduce pain and inflammation in arthritis patients; however, improved repair and mobility of joints still are the major concerns. Magnesium oil (MO) improves joint mobility and repair; therefore, MO-assisted transdermal delivery of Mtx was aimed.Methods: MO integrated Mtx nanoemulsion (Mtx-MONE) was prepared with uniform size (175 ± 35.4 nm), pH (6.15 ± 0.3) near to skin pH, and high entrapment efficiency (65 ± 8.6%). Mtx-MONE was transformed to nanogel (Mtx-MONEG) with semisolid consistency (43,408 ± 77.72 cP) and good spreadability (3.63 ± 0.033 mJ).Results: Mtx-MONEG showed significant reduction in oedema, arthritic scores, level of inflammatory cytokines, and improved walking as compared to diseased control. MO offered additional improvements in joints, mobility, and repair.Conclusion: Transdermal delivery of Mtx has been successfully achieved by Mtx-MONEG. Tremendous recovery from inflammation, improved joints mobility and repair, and reduced pain strongly support the use of MO as an adjutant of Mtx for improved transdermal application.

Abstract
Objective: To study the correlation between left atrial sphericity (LASP) and thromboembolic events (TE) in patients with atrial fibrillation (AF). Methods: This study was conducted in patients with AF underwent radiofrequency ablation in the Department of Cardiology of First Affiliated Hospital of Zhengzhou University from January 2011 to October 2018. The AF patients with TE (study group, n=157) and the AF patients without TE (control group, n=157) were matched for age and gender. The differences of LASP and other related indexes between the two groups were compared, and the correlation between LASP and TE was analyzed by conditional logistic regression. The receiver operating characteristic (ROC) curve was drawn to analyze the diagnostic value of LASP for TE. Results: (1) The LASP in the study group was significantly higher than that in the control group [ (87.5±7.1) % vs. (82.8±6.1) %, P=0.001]. (2) Conditional logistic regression analyses showed that LASP (OR=1.10, 95%CI 1.05-1.16, P=0.001), left atrial volume index (OR=1.01, 95%CI 1.00-1.02, P=0.016) and CHA(2)D-VASc score (OR=1.77, 95%CI 1.30-2.41, P=0.001) were independently and positively correlated with TE. (3) The ROC curve analysis showed that the area under the curve (AUC) of left atrial sphericity (AUC=0.712, 95%CI 0.656-0.768, P=0.001) was larger than the AUC of either left atrial volume index (AUC=0.650, 95%CI 0.589-0.710, P=0.001) or CHA(2)D-VASc score (AUC=0.612, 95%CI 0.550-0.674, P=0.001). (4) CHA(2)D-VASc-LASP(2) score was positively correlated with TE (OR=1.95, 95%CI 1.55-2.42, P=0.001). Conclusion: LASP is independently and positively correlated with TE in patients with AF.

Abstract
Systematically carried out over the past forty years economic reforms have given impetus to the development of the financial industry in China. Any changes suggest new approaches in the management system. Despite the results obtained there are some problems in the financial industry of China. In modern China there is a synthesis of Western and Eastern management theories, but it is necessary to pay tribute to traditional values, that influence on the thinking of leaders. The problems of human resource management in China in the financial industry have been considered in the article. The areas, where the most revolutionary changes are currently taking place, such as cross-border e-commerce, also have been indicated. In China, the proliferation of the Internet finance industry has been made possible by the surge in e-commerce. The fundamental factor in the psychology of the Chinese is Confucianism, on which they rely in all spheres of life. Despite the fact that in modern China there is a synthesis of the Western and Eastern theories of governance, it is necessary to pay tribute to the traditional values, which influence the thinking of the leaders of Chinese organizations. But new areas of activity require other, more advanced approaches to personnel training. The advantages and disadvantages of human resources management in the banking sector of China have been considered in the article. As a result of the analysis of indicators and problems of personnel management in the financial sphere, the main conclusions and recommendations on the structure of human resource management at this stage of improving society in China have been presented.

Abstract
OBJECTIVE To investigate the clinical efficacy and safety of transforaminal endoscopic spine system (TESSYS) in treating the prolapse of lumbar intervertebral disc. PATIENTS AND METHODS 462 patients with prolapse of lumbar intervertebral disc who were treated in our hospital from June 2012 to May 2016 were enrolled. All patients were randomly divided into 2 groups: the study group (n=231) and the control group (n=231). Patients in the study group received TESSYS, while those in the control group received conventional surgical treatment with posterior approach. Venous blood was collected before the surgery and 6 h, 12 h, 24 h, and 48 h after surgery. C reactive protein (CRP), interleukin-6 (IL-6), creatine phosphokinase (CPK) and white blood cell (WBC) in each patient were measured. The operation time, intraoperative blood loss, length of stay, postoperative ambulation time and complications were compared between the two groups. Clinical efficacy before and after surgery (1st day, 1st month, 3rd month, and 6th month after surgery) was evaluated according to visual analogue scale (VAS), Oswestry disability index (ODI) and modified MacNab criteria. RESULTS The operation time, intraoperative blood loss, length of stay, postoperative ambulation time and complications of patients in the study group were less than those of the control group (p<0.05). There were no significant differences in VAS score and ODI score on the 1st day before surgery, 1st day, 1st, 3rd, and 6th month after surgery (p>0.05). According to the improved MacNab standard, the excellent and good rate was 87.88% in the study group and 84.85% in the control group, the difference was not statistically significant (p>0.05). There were no significant differences in CRP, IL-6, CPK and WBC between the two groups before surgery (p>0.05). Postoperative levels of CRP, IL-6, CPK, and WBC in study group were better than those in control group, the differences were statistically significant (p<0.05). CONCLUSIONS TESSYS has the advantages of less bleeding, less traumatic reactions, fewer complications, rapid postoperative recovery, and exact short-term effect in treatment for prolapse of lumbar intervertebral disc.

Abstract
BACKGROUND AND PURPOSE In patients with SAH with multiple intracranial aneurysms, often the hemorrhage pattern does not indicate the rupture source. Angiographic findings (intracranial aneurysm size and shape) could help but may not be reliable. Our purpose was to test whether existing parameters could identify the ruptured intracranial aneurysm in patients with multiple intracranial aneurysms and whether composite predictive models could improve the identification. MATERIALS AND METHODS We retrospectively collected angiographic and medical records of 93 patients with SAH with at least 2 intracranial aneurysms (total of 206 saccular intracranial aneurysms, 93 ruptured), in which the ruptured intracranial aneurysm was confirmed through surgery or definitive hemorrhage patterns. We calculated 13 morphologic and 10 hemodynamic parameters along with location and type (sidewall/bifurcation) and tested their ability to identify rupture in the 93 patients. To build predictive models, we randomly assigned 70 patients to training and 23 to holdout testing cohorts. Using a linear regression model with a customized cost function and 10-fold cross-validation, we trained 2 rupture identification models: RIMC using all parameters and RIMM excluding hemodynamics. RESULTS The 25 study parameters had vastly different positive predictive values (31%-87%) for identifying rupture, the highest being size ratio at 87%. RIMC incorporated size ratio, undulation index, relative residence time, and type; RIMM had only size ratio, undulation index, and type. During cross-validation, positive predictive values for size ratio, RIMM, and RIMC were 86% ± 4%, 90% ± 4%, and 93% ± 4%, respectively. In testing, size ratio and RIMM had positive predictive values of 85%, while RIMC had 92%. CONCLUSIONS Size ratio was the best individual factor for identifying the ruptured aneurysm; however, RIMC, followed by RIMM, outperformed existing parameters.

Abstract
Objective To analyze the pathogenic community diversity of dental caries patients from Tu, Hui, Tibetan, and Han Chinese ethnic groups. Methods Forty saliva samples were collected from the following patients with dental caries: Tu from Huzhu County (n = 10), Hui from Ping’an County (n = 10), Han from Xining city (n = 10), and Tibetan from Yushu (n = 10). High-throughput sequencing of bacterial 16S rRNA genes (V3-V4) was performed using the Illumina MiSeq sequencing platform. Results Based on 97% similarity clustering, operational taxonomic units of Tu, Hui, Tibetan, and Han ethnic groups were 181, 210, 38, and 67, respectively. In Tu patients, 11 phyla, 19 classes, and 89 genera were identified, compared with 13 phyla, 21 classes, and 113 genera in Hui patients, two phyla, four classes, and 21 genera in Tibetan patients, five phyla, nine classes, and 34 genera in Han patients, and four phyla, five classes, and 12 genera from the control group. The main pathogens of dental caries included Veillonella, Aggregatibacter, Leptotrichia, Bacteroides, Granulicatella, Streptococcus, and Prevotella. Conclusion The pathogenic microorganisms of dental caries differ greatly among Tu, Hui, Tibetan, and Han ethnic groups. These findings provide a theoretical basis for the effective prevention and treatment of dental caries in different Chinese populations.
