Abstract
PURPOSE Thoracic aortic dissection (TAD) is a life-threatening cardiovascular disease that often results in sudden cardiac death (SCD). However, the genetic characteristics of individuals with TAD confirmed at autopsy have been rarely studied. Our objective was to determine the prevalence of pathogenic variants in TAD-associated genes in a cohort of sporadic deaths resulting from spontaneous rupture of TAD and identify relevant genotype-phenotype relationships in Han Chinese population. METHODS We included sixty-one consecutive sporadic decedents whose primary cause of death was spontaneous rupture of TAD, and performed a whole exome sequencing based strategy comprising 26 known TAD-associated genes. RESULTS We identified 7 pathogenic or likely pathogenic (P/LP) variants in 7 cases (11.48 %) and 22 variants of uncertain significance (VUS) in 22 cases (36.07 %). The FBN1 gene was found to be the major disease-causing gene. Notably, TAD decedents with P/LP variant exhibited significantly earlier mortality. Moreover, we reported for the first time that TAD decedents with P/LP variant had a shorter diagnosis and treatment time. CONCLUSION Our study investigated the genetic characteristics of TAD individuals confirmed until autopsy in Han Chinese population. The findings enhanced the understanding of the genetic underpinnings of TAD and have significant implications for clinical management and forensic investigations.

Abstract
A well-defined Ru(II)-PNP complex demonstrated high activity in the anti-Markovnikov hydroalkylation of nonpolarized terminal alkenes via hydrazones. Hydrazone served as a carbanion equivalent to combine with the electrophilic alkene substrate upon activation by the ruthenium catalyst, forming a new C-C bond in a concerted pathway with N2 as the only theoretical byproduct. Experimental and computational studies suggested the existence of a push-pull interaction that activated the alkene for hydrazone addition and then deduced the mechanism.

Abstract
PURPOSE The safety of laparoscopic inguinal-hernia repair must be carefully evaluated in elderly patients. Very little is known regarding the safety of the laparoscopic approach in elderly patients under surgical and medical co-management (SMC). Therefore, this study evaluated the safety of the laparoscopic approach in elderly patients, especially patients with multiple comorbidities under SMC. METHODS From January 2012 to December 2021, patients aged ≥ 65 years who underwent open or laparoscopic inguinal-hernia repair during hospitalization were consecutively enrolled. Postoperative outcomes included major and minor operation-related complications, and other adverse events. To reduce potential selection bias, propensity score matching was performed between open and laparoscopic groups based on patients' demographics and comorbidities. RESULTS A total of 447 elderly patients who underwent inguinal-hernia repair were enrolled, with 408 (91.3%) underwent open and 39 (8.7%) laparoscopic surgery. All postoperative outcomes were comparable between open and laparoscopic groups after 1:1 propensity score matching (all p > 0.05). Moreover, compared to the traditional care group (n = 360), a higher proportion of the SMC group (n = 87) was treated via the laparoscopic approach (18.4% vs. 6.4%, p = 0.00). In the laparoscopic approach subgroup (n = 39), patients in the SMC group (n = 16) were older with multiple comorbidities but were at higher risks of only minor operation-related complications, compared to those in the traditional care group. CONCLUSIONS Laparoscopic inguinal-hernia repair surgery is safe for elderly patients, especially those with multiple comorbidities under SMC.

Abstract
BACKGROUND Mitral annular disjunction (MAD) is an under-recognised phenotype associated with severe ventricular arrhythmias. Limited knowledge has been gained on its molecular genesis. METHODS A total of 150 unrelated deceased Chinese were collected for whole-exome sequencing, with analysis focusing on a panel of 118 genes associated with 'abnormal mitral valve morphology'. Cases were prespecified as 'longitudinally extensive MAD (LE-MAD)' or 'longitudinally less-extensive MAD (LLE-MAD)' according to the gross disjunctional length with a cut-off of 4.0 mm. The pedigree investigation was conducted on a case carrying an ultra-rare (minor allele frequency <0.1%) deleterious variant in DCHS1. RESULTS Seventy-seven ultra-rare deleterious variants were finally identified. Exclusively, 12 ultra-rare deleterious variants distributed in nine genes occurred in LE-MAD, which were ANK1, COL3A1, DCHS1, FBN2, GNPTAB, LZTR1, PLD1, RYR1 and VPS13B. Ultra-rare deleterious variants in those nine genes were predominantly distributed in LE-MAD compared with LLE-MAD (28% vs 5%, OR 7.30, 95% CI 2.33 to 23.38; p<0.001), and the only gene related to LE-MAD with borderline significance was DCHS1. LE-MAD was consistently observed in a sizeable Chinese family, in which LE-MAD independently co-segregated with an ultra-rare deleterious variant in DCHS1, rs145429962. CONCLUSION This study initially proposed that isolated LE-MAD might be a particular phenotype of MAD with a complex genetic predisposition. Deleterious variants in DCHS1 might be associated with the morphogenesis of LE-MAD.

Abstract
BACKGROUND Hypertrophic cardiomyopathy (HCM) is predominantly caused by mutations in sarcomeric genes. However, a subset of cases is attributed to genetic disorders unrelated to sarcomeric genes, such as Noonan syndrome (NS) and other RASopathies. In this study, we present a family with a history of sudden cardiac death (SCD) and focus on two adults with syndromic left ventricular hypertrophy (LVH). METHODS Clinical evaluations, including echocardiography, were conducted to assess cardiac manifestations. Whole-exome sequencing was performed to identify potential genetic variants underlying syndromic LVH in the study participants. RESULTS Whole-exome sequencing revealed a missense variant in the RAF1 gene, c.782C>T (p.Pro261Leu). This variant confirmed the diagnosis of NS in the affected individuals. CONCLUSION The findings of this study underscore the importance of family history investigation and genetic testing in diagnosing syndromic LVH. By identifying the underlying genetic cause, clinicians can better understand the etiology of RAS-HCM and its association with SCD in young adults.

Abstract
Objective: To describe the current status and trends in the treatment of patent ductus arteriosus (PDA) among very preterm infants (VPI) admitted to the neonatal intensive care units (NICU) of the Chinese Neonatal Network (CHNN) from 2019 to 2021, and to compare the differences in PDA treatment among these units. Methods: This was a cross-sectional study based on the CHNN VPI cohort, all of 22 525 VPI (gestational age<32 weeks) admitted to 79 tertiary NICU within 3 days of age from 2019 to 2021 were included. The overall PDA treatment rates were calculated, as well as the rates of infants with different gestational ages (≤26, 27-28, 29-31 weeks), and pharmacological and surgical treatments were described. PDA was defined as those diagnosed by echocardiography during hospitalization. The PDA treatment rate was defined as the number of VPI who had received medication treatment and (or) surgical ligation of PDA divided by the number of all VPI. Logistic regression was used to investigate the changes in PDA treatment rates over the 3 years and the differences between gestational age groups. A multivariate Logistic regression model was constructed to compute the standardized ratio (SR) of PDA treatment across different units, to compare the rates after adjusting for population characteristics. Results: A total of 22 525 VPI were included in the study, with a gestational age of 30.0 (28.6, 31.0) weeks and birth weight of 1 310 (1 100, 1 540) g; 56.0% (12 615) of them were male. PDA was diagnosed by echocardiography in 49.7% (11 186/22 525) of all VPI, and the overall PDA treatment rate was 16.8% (3 795/22 525). Of 3 762 VPI who received medication treatment, the main first-line medication used was ibuprofen (93.4% (3 515/3 762)) and the postnatal day of first medication treatment was 6 (4, 10) days of age; 59.3% (2 231/3 762) of the VPI had been weaned from invasive respiratory support during the first medication treatment, and 82.2% (3 092/3 762) of the infants received only one course of medication treatment. A total of 143 VPI underwent surgery, which was conducted on 32 (22, 46) days of age. Over the 3 years from 2019 to 2021, there was no significant change in the PDA treatment rate in these VPI (P=0.650). The PDA treatment rate decreased with increasing gestational age (P<0.001). The PDA treatment rates for VPI with gestational age ≤26, 27-28, and 29-31 weeks were 39.6% (688/1 737), 25.9% (1 319/5 098), and 11.4% (1 788/15 690), respectively. There were 61 units having a total number of VPI≥100 cases, and their rates of PDA treatment were 0 (0/116)-47.4% (376/793). After adjusting for population characteristics, the range of standardized ratios for PDA treatment in the 61 units was 0 (95%CI 0-0.3) to 3.4 (95%CI 3.1-3.8). Conclusions: From 2019 to 2021, compared to the peers in developed countries, VPI in CHNN NICU had a different PDA treatment rate; specifically, the VPI with small birth gestational age had a lower treatment rate, while the VPI with large birth gestational age had a higher rate. There are significant differences in PDA treatment rates among different units.

Abstract
Diboron compounds are important reagents in a series of transition metal catalyzed or metal-free borylation reactions. We describe herein a unique reactivity of 4-Bpin-o-carborane with ketones under basic conditions, leading to sequential cage carbon alkylation, B-B bond activation and unexpected O-migration. The reaction was compatible with a good substrate scope including dialkyl or alkyl aryl ketones. The reaction mechanism is also proposed, involving cage CH deprotonation, nucleophilic attack of ketone, and O-migration along with B-B bond cleavage.

Abstract
A novel method for the formation of Csp3-P(III) bonds via the nickel-catalyzed cross-coupling between Umpolung carbonyls and phosphine chlorides is reported herein, leading to a series of alkylphosphines, which are characterized as sulfides or borane-phosphine complexes in moderate to good yields after further transformation. Invaluable free alkylphosphines can be easily obtained by desulfurization or deboration of products. A possible mechanistic pathway is also discussed. This report represents the first example of using renewable carbonyls as latent organometallic reagent surrogates forcross-coupling with heteroatom electrophiles.

Abstract
An efficient Ir-catalyzed cage boron alkenylation of 1-(2'-picolyl)-o-carboranes with diarylacetylenes has been developed, leading to a wide variety of B-H geminal addition products via 1,2-carbon migration of alkynes. The steric effect of cage carbon substituents has a great impact on the regioselectivity of such alkenylation reactions.

Abstract
While classical cross-couplings are dominated by palladium and nickel catalysts, cobalt-based catalysts have shown unique advantages for such cross-coupling reactions in terms of higher catalytic activity and lower toxicity. Herein, we describe a novel cobalt-catalyzed alkyl-alkyl cross-coupling reaction of hydrazone with alkyl halides under mild reaction conditions, where the use of a PNP-type pincer ligand is essential for catalysis. Both aldehyde and ketone hydrazones are compatible with this reaction, giving a series of C(sp3)-C(sp3) coupling products in moderate to good yields.

Abstract
Objective: To explore the surgical strategy of nipple areola complex (NAC) management in central breast cancer. Methods: A retrospective analysis was conducted on 164 cases of central breast cancer who underwent surgery treatment from December 2017 to December 2020 in the Breast Center of Beijing Tongren Hospital, Capital Medical University. Prior to the surgery, the tumor-nipple distance (TND) and the maximum diameter of the tumor were measured by magnetic resonance imaging (MRI). The presence of nipple invagination, nipple discharge, and nipple ulceration (including nipple Paget's disease) were recorded accordingly. NAC was preserved in patients with TND≥0.5 cm, no signs of NAC invasion (nipple invagination, nipple ulceration) and negative intraoperative frozen pathological margin. All patients with signs of NAC involvement, TND<0.5 cm or positive NAC basal resection margin confirmed by intraoperative frozen pathology underwent NAC removal. χ(2) test or Fisher exact test was used to analyze the influencing factors. Results: Of the 164 cases of central breast cancer, 73 cases underwent breast-conserving surgery, 43 cases underwent nipple-areola complex sparing mastectomy (NSM), 34 cases underwent total mastectomy, and the remaining 14 cases underwent skin sparing mastectomy (SSM). Among the 58 cases of NAC resection (including 34 cases of total mastectomy, 14 cases of SSM, and 10 cases of breast-conserving surgery), 25 cases were confirmed tumor involving NAC (total mastectomy in 12 cases, SSM in 9 cases, and breast-conserving surgery in 4 cases). The related factors of NAC involvement included TND (P=0.040) and nipple invagination (P=0.031). There were no correlations between tumor size (P=0.519), lymph node metastasis (P=0.847), bloody nipple discharge (P=0.742) and NAC involvement. During the follow-up period of 12 to 48 months, there was 1 case of local recurrence and 3 cases of distant metastasis. Conclusions: For central breast cancer, data suggest that patients with TND≥0.5cm, no signs of NAC invasion (nipple invagination, nipple ulceration) and negative NAC margin in intraoperative frozen pathology should be treated with NAC preservation surgery, whereas for those with TND<0.5 cm or accompanied by signs of NAC invasion, NAC should be removed. In addition, nipple reconstruction can be selected to further improve the postoperative appearance of patients with central breast cancer.

Abstract
The asymmetric synthesis of chiral-at-cage o-carboranes, whose chirality is associated with the substitution patterns on the polyhedron, is of great interest as the icosahedral carboranes have wide applications in medicinal and materials chemistry. Herein we report an intermolecular Ir-catalyzed enantioselective B-H alkenylation for efficient and facile synthesis of chiral-at-cage o-carboranes with new skeletons under mild reaction conditions. Generally very good to excellent yields with up to 99% ee can be achieved in this Ir-catalyzed B-H alkenylation. The enantiocontrol model is proposed based on Density Functional Theory calculations in which the use of chiral phosphoramidite ligand is essential for such asymmetric o-carborane B-H alkenylation.

Abstract
Abstract
Background
Cancer is the second most common cause of death globally after cardiovascular (CV) disease. The present study sought to compare the trends in CV mortality between patients with and without cancer in the US over two decades (1999 to 2019), stratified by sociodemographic factors such as age, sex and geographical location.
Methods
In this retrospective study, the number of deaths, crude- and age-adjusted mortality rates between January 1, 1999, and December 31, 2019, were obtained from the Centers for Disease Control and Prevention Wide-Ranging Online Data for Epidemiologic Research (CDC WONDER) data set
Results
We examined a total of 53,422,612 deaths between 1999 and 2019; of which 33.4% were defined as CV mortality and 25.6% had malignancy. During this period, among patients with cancer, the age-adjusted mortality rate dropped by 52%. (Vs, 38% in patients with no malignancy). CV mortality was highest in patients with gastrointestinal and prostate malignancy where CV mortality accounts together for over 40% of all CV mortality in patients with cancer in 1999 and 33.6% in 2019. The age-adjusted CV mortality rate (per 100,000 people) of patients with GI and prostate cancer nearly halved over twenty years from 2.7 to 1.0 and 2.5 to 1.0.
The CV age-adjusted mortality rate dropped more significantly among patients with gastrointestinal, breast, and prostate malignancy than among patients with hematological malignancy (59–63% vs. 41%. We observed that crude CV mortality rates amongst patients with cancer declined over the study period in all age groups but was more prominent among patients over 65 years old than those aged 55–64 and under 55 (51%-55% Vs. 41%, 25%, respectively).Similar reductions in mortality in men and women (54% and 53% reduction) were observed
During the study period the decline in cardiovascular mortality was more prominent in metro areas which led to lower age adjusted CV mortality in Metro compared to non-Metro areas (5.7–6.3 vs 7.2). The decline in age adjusted CV mortality in patients with cancer differed significantly in different states
Conclusions
In our temporal analysis we show a 50% decline in CV mortality in the US over two decades in both male and female patients with cancer, that has exceeded the reduction in CV mortality seen in the non-cancer population. The greatest reductions in CV mortality were observed in patients with GI, breast and prostate malignancies, those residing in metro areas and in patients aged 65 and over.

Abstract
INTRODUCTION Primary retroperitoneal tumours (PRTs) are rare soft tissue tumours originating from the retroperitoneum. Although there has been considerable progress recently in diagnosis and treatment, the overall survival rate has not improved qualitatively. This study aimed to explore the clinical features, therapeutic strategies and prognosis of PRTs. METHODS Retrospective analysis of clinical data for 121 PRT patients admitted to Peking University Shenzhen Hospital from April 2003 to February 2017. RESULTS A total of 113 patients underwent surgery and 8 chose nonsurgical palliative treatment. There were 53 males and 68 females (ratio, 1:1.3; average age, 40.75 years), and the average tumour diameter was 9.69(2-40)cm. A total of 104 patients (92.04%) underwent complete resection, 5 (4.42%) underwent palliative resection and 21 (18.58%) underwent combined visceral resection. The pathological diagnosis was benign in 88 cases (72.73%) and malignant in 33 cases (27.27%). A total of 101 patients (83.47%) were followed for an average of 5.82 years. At the end of follow up, the recurrence and survival rates were 2.63% and 93.42% for benign tumours, respectively, and 24.00% and 60.00% for malignant tumours (p<0.01). CONCLUSIONS Imaging plays important roles in localising and characterising tumours, guiding treatment strategies. Complete tumour resection is key to reducing postoperative recurrence and improving survival. According to the postsurgical pathological results, combinations including radiotherapy, chemotherapy or targeted therapy are beneficial for improving prognosis.

Abstract
Objective: To investigate the effect of antibiotics application in perioperative period on carotid artery and serum interluekin-6 (IL-6) in chronic periodontitis (CP) rats with hyperlipidemia (HL) or diabetes mellitus (DM). Methods: The models of CP rats with HL or DM were established in different batches. The rats were divided into groups as follows: A and A' were normal control groups, n=7 in each group; B(HL) and B'(DM) were groups of HL and DM, n=7 in each; C(HL+CP) and C'(DM+CP) were groups of CP with HL and CP with DM, n=21 in each. After the establishment of the models, groups C and C' were divided into C1 and C1' non-intervention group, C2 and C2' simple tooth extraction group and C3 and C3' antibiotic-assisted tooth extraction, with 7 rats in each of the groups. Two time interventions were performed to extract experimental teeth (bilateral maxillary first and second molars) in groups C2, C2', C3 and C3'. Serum samples were collected at 5 time points before and after tooth extraction (T1: before the first tooth extraction; T2: one week after the first tooth extraction; T3, T4, T5: the first, third and fifth week after the second tooth extraction), respectively. The absolute content of IL-6 in serum was detected by enzyme-linked immunosorbent assay (ELISA). Ratio of the absolute content in the experimental groups and control groups were calculated as the relative content of IL-6. At the end of the experiments, all rats were euthanasia and the bifurcation vascular tissues of carotid artery were collected for the observation of the carotid artery pathology and plaque formation and the measurement of the thickness of carotid intimal-medial layer (IMT). Results: Carotid artery pathology observation showed the IMT in group C was significantly thickened and the group C2 was the most thickened one (compared with group A, P<0.01). Elastic fibers in groups C1 and C2 were disordered or even broken and disappeared, presenting typical atherosclerotic plaques, which were diffuse calcium salt deposits in the intimal-medial layers and protrude into the lumen. Elastic fibers in group C3 were ranged in ordered relatively without obvious fracture and the number of plaques was significantly reduced. The vascular walls in rats of groups B' and C' were incomplete, the IMTs had no obvious changes, elastic fibers were ranged disorderly and broken and the smooth muscle cells had vacuolar changes. In group C2', the vascular wall was significantly thinned and calcified plaques appeared in the artery, which showed multiple calcification lesions penetrating through the intimal-medial layer or even the whole layer. The vascular wall of group C3' was integrity and the elastic fibers arranged relatively clutter-free, the number of plaques was reduced. Results of detections of IL-6 showed the relative contents of IL-6 in groups B, B', C1, and C1' increased with time. At T3 time point, the relative contents of IL-6 in groups C2 and C3 reached the peak, C2 was 10.4 times of group A and C3 was 9.5 times of group A, and then decreased to different low levels. At T5 point, comparisons of the relative contents of IL-6 showed C3 < C2 < C1 (3.2 times, 5.4 times, 9.6 times of group A, respectively). The relative contents of IL-6 in groups C2' and C3' reached the peak at T2 point (4.9 times and 4.5 times of group A, respectively), and then decline with time. At T5 point, comparisons of the relative contents of IL-6 showed C3'< C2'< C1' (1.2 times, 1.4 times and 3.1 times of group A, respectively). Conclusions: Blood vessels were observed more obvious thickened in the tooth extraction without antibiotic of HL+CP rats with calcifications increase. Blood vessels of DM+CP rats became thin and fragile and even the integrity was damaged. Perioperative use of antibiotics might reduce the carotid artery lesions and decrease serum levels of inflammatory cytokines.

Abstract
We report on a precision energy loss measurement and theoretical investigation of 100 keV/u helium ions in a hydrogen-discharge plasma. Collision processes of helium ions with protons, free electrons, and hydrogen atoms are ideally suited for benchmarking plasma stopping-power models. Energy loss results of our experiments are significantly higher than the predictions of traditional effective charge models. We obtained good agreement with our data by solving rate equations, where in addition to the ground state, also excited electronic configurations were considered for the projectile ions. Hence, we demonstrate that excited projectile states, resulting from collisions, leading to capture-, ionization-, and radiative-decay processes, play an important role in the stopping process in plasma.

Abstract
ABSTRACT The function and protection of the parathyroid glands are increasingly popular research topics. New Zealand white rabbits are the most commonly used animal model of parathyroid ischemia. However, information on the vasculature of their parathyroid glands is limited. We used 94 healthy New Zealand white rabbits, 3-4 months of age and 2-3kg in weight, for exploration of the parathyroid glands, which were stained using hematoxylin and eosin (HE) after removal. The following types were classified according to the relationship between the position of the inferior parathyroid gland and the thyroid: Type A, Close Type, Type B, and Distant Type. There were 188 cases, 4 where the inferior parathyroid glands were located near the dorsal side of thyroid (2.13%), 8 where the inferior parathyroid glands were located superior to the upper pole of the thyroid (4.26%), 20 where the inferior parathyroid glands were located parallel to the thyroid (10.64%), and 155 cases where the inferior parathyroid glands were located inferior to the lower pole of thyroid (82.45%). Identifying the location and classifying the vasculature of the parathyroid glands in New Zealand white rabbits will provide an anatomical model to assist in future research.

Abstract
This study aimed to determine the impact of Lactobacillus plantarum PC170 concurrent with antibiotic treatment and/or during the recovery phase after antibiotic treatment on the body weight, faecal bacterial composition, short-chain fatty acids (SCFAs) concentration, and splenic cytokine mRNA expression of mice. Orally administrated ceftriaxone quantitatively and significantly decreased body weight, faecal total bacteria, Akkermansia muciniphila, and Lactobacillus plantarum, and faecal SCFAs concentration. Ceftriaxone treatment also dramatically altered the faecal microbiota with an increased Chao1 index, decreased species diversities and Bacteroidetes, and more Firmicutes and Proteobacteria. After ceftriaxone intervention, these changes all gradually started to recover. However, faecal microbiota diversities were still totally different from control by significantly increased α- and β-diversities. Bacteroidetes all flourished and became dominant during the recovery process. However, mice treated with PC170 both in parallel with and after ceftriaxone treatment encouraged more Bacteroidetes, Verrucomicrobia, and Actinobacteria, and the diversity by which to make faecal microbiota was very much closer to control. Furthermore, the expression of splenic pro-inflammatory cytokine tumour necrosis factor-α mRNA in mice supplemented with PC170 during the recovery phase was significantly lower than natural recovery. These results indicated that antibiotics, such as ceftriaxone, even with short-term intervention, could dramatically damage the structure of gut microbiota and their abilities to produce SCFAs with loss of body weight. Although such damages could be partly recovered with the cessation of antibiotics, the implication of antibiotics to gut microbiota might remain even after antibiotic treatment. The selected strain PC170 might be a potential probiotic because of its contributions in helping the host animal to remodel or stabilise its gut microbiome and enhancing the anti-inflammatory response as protection from the side effects of antibiotic therapy when it was administered in parallel with and after antibiotic treatment.

Abstract
Objective: To investigate the types and distribution of blood-sucking insects and arboviruses in Inner Mongolia autonomous region, and provide basic data for the prevention of arbovirus transmitted disease. Methods: Blood-sucking insects were collected by lamp trapping method in nature. Mosquito samples were classified according to morphologic characteristics and then stored at liquid nitrogen. Viruses were isolated in cell culture and characterized, using molecular biological methods. Results: A total of 24 240 mosquitoes and 17 110 aphids were collected from 2 sites of 5 counties (Flags) in Inner Mongolia in 2014 and during 2017-2018. Among them, Japanese encephalitis virus gene was detected in Culex pipiens pallens, and 4 virus strains isolates which could be stably passaged. The isolates were identified as Getah virus and densonucleosis virus by molecular biology identification. Phylogenetic analysis on the E2 gene of the Getah virus (NMDK1813-1) showed that it belonged to the same evolutionary branch of the Gansu isolates (GS10-2) and having six common amino acid variation sites. Conclusions: The emergence of Japanese encephalitis virus and Getah virus from specimen of mosquitoes in Inner Mongolia indicated the new challenges on the prevention and control of arbovirus and related diseases. The results pf this study provided basic data for the prevention and control stretagies of arbovirus transmitted diseases in Inner Mongolia.

Abstract
BACKGROUND Atopic dermatitis (AD) is the most common skin disorder in infancy. However, the diagnosis and definite significance of infantile AD remains a debated issue. OBJECTIVE To analyse the phenotypes of AD in infancy, to establish diagnostic criteria and to estimate the prevalence of this condition in China. METHODS This is a multicentric study, in which 12 locations were chosen from different metropolitan areas of China. Following careful and complete history-taking and skin examination, the definite diagnosis of AD was made and the severity based on the SCORAD index was determined by local experienced dermatologists. Based on the detailed phenotyping, the major and representative clinical features of infantile AD were selected to establish the diagnostic criteria and evaluate their diagnostic efficacy. RESULTS A total of 5967 infants were included in this study. The overall point prevalence of AD was 30.48%. The infantile AD developed as early as at the second month of life, and its incidence peaked in the third month of life at 40.81%. The proportion of mild, moderate and severe AD was 67.40%, 30.57% and 2.03%, respectively. The most commonly seen manifestations in the infantile AD were facial dermatitis (72.07%), xerosis (42.72%) and scalp dermatitis (27.93%). We established the novel diagnostic criteria of infants, which included: (i) onset after 2 weeks of birth; (ii) pruritus and/or irritability and sleeplessness comparable with lesions; and (iii) all two items above with one of the following items can reach a diagnosis of AD: (i) eczematous lesions distributed on cheeks and/or scalp and/or extensor limbs, and (ii) eczematous lesions on any other parts of body accompanied by xerosis. CONCLUSIONS In China, the prevalence of AD in infancy is 30.48% according to clinical diagnosis of dermatologists. The novel Chinese diagnostic criteria for AD in infants show a higher sensitivity and comparable specificity.

Abstract
Objective: To evaluate the value of apparent diffusion coefficient (ADC) histogram in neonatal brain alteration with congenital heart disease (CHD). Methods: MRIs of 60 neonates with CHD confirmed by echocardiography were retrospectively analyzed in Children's Hospital of Nanjing Medical University from January 2012 to December 2016.Twenty-two MRIs of neonates with mild pneumonia or scalp hematoma who were suspicious of brain disease but normal MRI findings were enrolled as normal control.MRIcron and ImgJ softwares were used to acquire ADC histogram.The correlation between the gestational age and ADC histogram values were calculated respectively.Then t-test was used to analyze the differences of the histogram values and the diagnostic efficacy of different parameters was analyzed using the receiver operating characteristic curve. Results: The ADC values were significantly correlated with the gestational age (P<0.05). The 70th-90th ADC, skewness, kurtosis and variance were statistically significant (P<0.05). The area under the curve of the 90th ADC value was the largest at 0.698. Conclusions: The ADC histogram can quantify and objectively provide more diffusion information of brain tissue. It is a rapid and feasible quantitative method to identify brain changes in neonates with CHD.

Abstract
Objective: To explore the relationship between job stress, work engagement and depressive symptoms of State Grid workers, and to analyze the mediating effect of work engagement between job stress and depressive symptoms. Methods: A cross-sectional survey was conducted to investigate 845 employees from a State Grid company, using the brief job stress questionnaire, the Patient Health Questionnaire (PHQ-9) and 9-item Utrecht Work Engagement Scale (UWES-9) in March 2017. Results: The average score of work engagement was 4.49±1.42, the mean value of job stress was 1.15±0.33, the average score of depressive symptoms was 6.44±4.30, and the positive rate of depressive symptoms was 66.9%.There was a negative correlation between work engagement with both job stress and depressive symptoms (r=-0.193, -0.397, both P<0.01) , and job stress was positively correlated with depressive symptoms (r=0.260, P<0.01) . The relationship between job stress and depressive symptoms was partly mediated by work engagement, and the mediating effect accounted for 27.2% of the total effect. Conclusion: The work engagement of State Grid staff acts as the mediator between job stress and depressive symptoms, alleviating the depressive symptoms caused by job stress.

Abstract
Carborane cage chirality is an outstanding issue of great interest as the icosahedral carboranes have wide applications in medicinal and materials chemistry. The synthesis of optically active carborane derivatives, whose chirality is associated with the substitution patterns on the polyhedron, will open new avenues to carborane chemistry. We report herein an efficient method to achieve chiral-at-cage arylation of o-carboranes with high regio- and enantioselectivities by a strategy of palladium-catalyzed asymmetric intramolecular B-H arylation and cyclization. This represents the first example of the enantioselective reaction on carboranes, providing an efficient way for the construction of chiral-at-cage compounds with new skeletons.
