Abstract
Nasopharyngeal tuberculosis refers to the tuberculosis in the nasopharynx, which is mainly treated with systemic chemotherapy with anti-tuberculosis drugs. Here, we reported a case of nasopharyngeal tuberculosis treated by cryosurgery combined with local spraying of isoniazid on the basis of systemic chemotherapy with anti-tuberculosis drugs. By reviewing the case data and relevant literature, we understood the clinical manifestations, diagnosis and differential diagnosis of the disease, improved everyone's understanding of the disease, and proposed a new method of cryosurgery combined with local spraying of isoniazid for the treatment of nasopharyngeal tuberculosis for clinical discussion.

Abstract
Molybdenum sulfide (MoS2) as an emerging optoelectronic material, shows great potential for phototransistors owing to its atomic thickness, adjustable band gap, and low cost. However, the phototransistors based on MoS2have been shown to have some issues such as large gate leakage current, and interfacial scattering, resulting in suboptimal optoelectronic performance. Thus, Al-doped hafnium oxide (Hf1-xAlx) is proposed to be a dielectric layer of the MoS2-based phototransistor to solve this problem because of the relatively higher crystallization temperature and dielectric constant. Here, a high-performance MoS2phototransistor with Hf1-xAlxO gate dielectric layer grown by plasma-enhanced atomic layer deposition has been fabricated and studied. The results show that the phototransistor exhibits a high responsivity of 2.2 × 104A W-1, a large detectivity of 1.7 × 1017Jones, a great photo-to-dark current ratio of 2.2 × 106%, and a high external quantum efficiency of 4.4 × 106%. The energy band alignment and operating mechanism were further used to clarify the reason for the enhanced MoS2phototransistor. The suggested MoS2phototransistors could provide promising strategies in further optoelectronic applications.

Abstract
Platelets are important cells in hemostatic and coagulative reactions. Interestingly, platelets-related immunopathological mechanism and clinical research have become one of the hot research topics in tuberculosis at home and abroad in recent years. Platelets get involved in host chronic inflammation and pulmonary immune response, thus playing a negative regulatory role in tuberculosis. This is achieved through direct internalization of Mycobacterium tuberculosis and indirect interaction with immune cells. In addition, patients with tuberculosis often have thrombocytosis, and there is increasing evidence that anti-platelet therapy as a host-directed therapy has demonstrable clinical benefit in tuberculosis control. Platelet inhibition may be an emerging therapeutic strategy for tuberculosis. This review aims to highlight the research progress in platelets and tuberculosis.

Abstract
Widespread species that inhabit diverse environments possess large population sizes and exhibit a high capacity for environmental adaptation, thus enabling range expansion. In contrast, narrow-range species are confined to restricted geographical areas and are ecologically adapted to narrow environmental conditions, thus limiting their ability to expand into novel environments. However, the genomic mechanisms underlying the differentiation between closely related species with varying distribution ranges remain poorly understood. The Niviventer niviventer species complex (NNSC), consisting of highly abundant wild rats in Southeast Asia and China, offers an excellent opportunity to investigate these questions due to the presence of both widespread and narrow-range species that are phylogenetically closely related. In the present study, we combined ecological niche modeling with phylogenetic analysis, which suggested that sister species cannot be both widespread and dominant within the same geographical region. Moreover, by assessing heterozygosity, linkage disequilibrium decay, and Tajima's D analysis, we found that widespread species exhibited higher genetic diversity than narrow-range species. In addition, by exploring the "genomic islands of speciation", we identified 13 genes in highly divergent regions that were shared by the two widespread species, distinguishing them from their narrow-range counterparts. Functional annotation analysis indicated that these genes are involved in nervous system development and regulation. The adaptive evolution of these genes likely played an important role in the speciation of these widespread species.

Abstract
Objective: To investigate the clinical characteristics and risk factors of critical burn patients complicated with invasive fungal infection. Methods: A retrospective case series study was conducted. From January 2017 to December 2022, 88 critical burn patients combined with invasive fungal infection who met the inclusion criteria were admitted to Zhengzhou First People's Hospital, including 61 males and 27 females, aged 26-74 years. Data on invasive fungal infection sites and the detection of pathogens in patients were recorded. According to the survival outcome within 28 days after admission, the patients were divided into survival group (63 cases) and death group (25 cases). The following data of patients were compared between the two groups, including the basic data and injuries of patients at admission such as age, sex, body weight, total burn area, combination of inhalation injury, combination of hypertension and diabetes, acute physiology and chronic health status evaluation Ⅱ (APACHE Ⅱ) score, and admission time after burns, the levels of blood biochemical indexes within 24 h after admission such as white blood cell count, platelet count, red blood cell count, monocyte count, neutrophil count, lymphocyte count, alanine transaminase, aspartate transaminase, glucose, creatinine, urea nitrogen, D-dimer, galactomannan (GM), 1,3-β-D glucan, and creatine kinase, the application of invasive procedures and vasoactive drugs during the treatment such as continuous renal replacement therapy, ventilator-assisted breathing, tracheotomy, deep vein catheterization, skin grafting >2 times, the levels of infection indicators on post admission day (PAD) 1, 3, 7, and 14 including C-reactive protein (CRP), procalcitonin, lactic acid, interleukin-6 (IL-6), and tumor necrosis factor-α (TNF-α), and the detection of pathogens in the process of treatment. Data were statistically analyzed with independent sample t test, analysis of variance for repeated measurement, chi-square test, Mann-Whitney U test, and Bonferroni correction. Multivariate logistic regression analysis was performed to screen the independent risk factors that affected death of critical burn patients complicated with invasive fungal infection. Results: The main sites of invasive fungal infection were the wounds (67 cases) and blood stream (46 cases), with Candida fungi (58 strains) as the main strain for fungi infection, and there were a total of 30 cases of infection with mixed pathogenic bacteria. Compared with those in survival group, the APACHE Ⅱ score, proportions of combination with inhalation injury and hypertension of patients in death group were significantly increased (t=2.11, with χ2 values of 6.26 and 9.48, respectively, P<0.05), while the other basic data and injury condition had no significant changes (P>0.05). Compared with those in survival group, the levels of D-dimer, GM, and 1,3-β-D glucan of patients in death group were significantly increased within 24 h after admission (with t values of 2.42, 2.05, and 2.21, respectively, P<0.05), while the other blood biochemical indexes within 24 h after admission, as well as the proportions of applying invasive procedures and application of vasoactive drugs during the treatment process were not significantly changed (P>0.05). The levels of infection indicators of patients on PAD 1 and 3 were similar between the two groups (P>0.05). The procalcitonin level on PAD 7 and the levels of CRP, procalcitonin, lactic acid, IL-6, and TNF-α on PAD 14, as well as the proportion of infection with mixed pathogenic bacteria of patients in death group were significantly higher than those in survival group (with t values of 4.69, 3.89, 6.70, 6.14, 4.65, and 3.26, respectively, χ2=12.67, P<0.05). Multivariate logistic regression analysis showed that combination with inhalation injury, combination with hypertension, and infection with mixed pathogenic bacteria were independent risk factors for death of critical burn patients complicated with invasive fungal infection (with odds ratios of 5.98, 4.67, and 6.19, respectively, 95% confidence intervals of 1.42-15.39, 1.41-25.28, and 1.86-20.58, respectively, P<0.05). Conclusions: The main sites of infection in critical burn patients complicated with invasive fungal infection are the wounds and blood stream, with Candida fungi as the main strain for fungi infection, and a large proportion of infection with mixed pathogenic bacteria. The combined inhalation injury, combined hypertension, and infection with mixed pathogenic bacteria are the independent risk factors for the death of those patients.

Abstract
Objective: To establish reference values for carotid intima-media thickness (CIMT) of adult dwellers in Shenzhen City. Methods: The study was conducted based on the Shenzhen heart failure epidemiological survey from 2021 to 2022. In this survey, residents aged 18 years and above in Shenzhen were selected by using a multi-stage stratified random sampling method. General information, cardiovascular disease (CVD) related behavior and carotid ultrasound examination and etc. were collected from the participants. People with CVD factors, a history of atherosclerotic cardiovascular disease, carotid plaque or having no carotid ultrasound examination results were excluded. The parameter regression model based on fractional polynomial was used to establish the reference values of CIMT by age and sex. Results: A total of 2 163 healthy individuals were enrolled in the final analysis, including 576 males (26.6%) and 1 587 females (73.4%). The fractional polynomial regression of the CIMT mean and standard deviation was obtained. For men, the regression was meanCIMT=0.324 7+0.006 9×age and SDCIMT=0.076 9+0.001 2×age. For women, the regression was meanCIMT=0.354 9+0.005 4×age and SDCIMT=0.041 6+0.002 0×age. Conclusion: The age and sex reference values for CIMT of adult people in Shenzhen established in this study could provide the latest reference standards for early screening of subclinical CVD.

Abstract
In the search for natural reservoirs of hepatitis C virus (HCV), a broad diversity of non-human viruses within the Hepacivirus genus has been uncovered. However, the evolutionary dynamics that shaped the diversity and timescale of hepaciviruses evolution remain elusive. To gain further insights into the origins and evolution of this genus, we screened a large dataset of wild mammal samples (n = 1,672) from Africa and Asia, and generated 34 full-length hepacivirus genomes. Phylogenetic analysis of these data together with publicly available genomes emphasizes the importance of rodents as hepacivirus hosts and we identify 13 rodent species and 3 rodent genera (in Cricetidae and Muridae families) as novel hosts of hepaciviruses. Through co-phylogenetic analyses, we demonstrate that hepacivirus diversity has been affected by cross-species transmission events against the backdrop of detectable signal of virus-host co-divergence in the deep evolutionary history. Using a Bayesian phylogenetic multidimensional scaling approach, we explore the extent to which host relatedness and geographic distances have structured present-day hepacivirus diversity. Our results provide evidence for a substantial structuring of mammalian hepacivirus diversity by host as well as geography, with a somewhat more irregular diffusion process in geographic space. Finally, using a mechanistic model that accounts for substitution saturation, we provide the first formal estimates of the timescale of hepacivirus evolution and estimate the origin of the genus to be about 22 million years ago. Our results offer a comprehensive overview of the micro- and macroevolutionary processes that have shaped hepacivirus diversity and enhance our understanding of the long-term evolution of the Hepacivirus genus.

Abstract
Although it is widely recognized that the ancestors of Native Americans (NAs) primarily came from Siberia, the link between mitochondrial DNA (mtDNA) lineage D4h3a (typical of NAs) and D4h3b (found so far only in East China and Thailand) raises the possibility that the ancestral sources for early NAs were more variegated than hypothesized. Here, we analyze 216 contemporary (including 106 newly sequenced) D4h mitogenomes and 39 previously reported ancient D4h data. The results reveal two radiation events of D4h in northern coastal China, one during the Last Glacial Maximum and the other within the last deglaciation, which facilitated the dispersals of D4h sub-branches to different areas including the Americas and the Japanese archipelago. The coastal distributions of the NA (D4h3a) and Japanese lineages (D4h1a and D4h2), in combination with the Paleolithic archaeological similarities among Northern China, the Americas, and Japan, lend support to the coastal dispersal scenario of early NAs.

Abstract
The evolutions of MHD instability behaviors and enhancement of both electrostatic and electromagnetic turbulence towards the plasma disruption have been clearly observed in the HL-2A plasmas. Two types of plasma disruptive discharges have been investigated for similar equilibrium parameters: one with a distinct stage of a small central temperature collapse ([Formula: see text] 5-10%) around 1 millisecond before the thermal quench (TQ), while the other without. For both types, the TQ phase is preceded by a rotating 2/1 tearing mode, and it is the development of the cold bubble from the inner region of the 2/1 island O-point along with its inward convection that causes the massive energy loss. In addition, the micro-scale turbulence, including magnetic fluctuations and density fluctuations, increases before the small collapse, and more significantly towards the TQ. Also, temperature fluctuations measured by electron cyclotron emission imaging enhances dramatically at the reconnection site and expand into the island when approaching the small collapse and TQ, and the expansion is more significant close to the TQ. The observed turbulence enhancement near the X-point cannot be fully interpreted by the linear stability analysis by GENE. Evidences suggest that nonlinear effects, such as the reduction of local [Formula: see text] shear and turbulence spreading, may play an important role in governing turbulence enhancement and expansion. These results imply that the turbulence and its interaction with the island facilitate the stochasticity of the magnetic flux and formation of the cold bubble, and hence, the plasma disruption.

Abstract
The family of Papilionidae (Lepidoptera: Papilionoidea) is a group of butterflies with high ecological and conservation value. The Hengduan Mountains (HMDs) in Southwest China is an important diversity centre for these butterflies. However, the spatial distribution pattern and the climate vulnerability of Papilionidae butterflies in the HDMs remain unknown to date. The lack of such knowledge has already become an obstacle in formulating effective butterfly conservation strategies. The present research compiled a 59-species dataset with 1938 occurrence points. The Maxent model was applied to analyse the spatial pattern of species richness in subfamilies Parnassiinae and Papilioninae, as well as to predict the response under the influence of climate change. The spatial pattern of both subfamilies in the HDMs has obvious elevation prevalence, with Parnassiinae concentrated in the subalpine to alpine areas (2500-5500 m) in western Sichuan, northwestern Yunnan and eastern Tibet, while Papilioninae is concentrated in the low- to medium-elevation areas (1500-3500 m) in the river valleys of western Yunnan and western Sichuan. Under the influence of climate change, both subfamilies would exhibit northward and upward range shifts. The majority of Parnassiinae species would experience drastic habitat contraction, resulting in lower species richness across the HDMs. In contrast, most Papilioninae species would experience habitat expansion, and the species richness would also increase significantly. The findings of this research should provide new insights and a clue for butterfly diversity and climatic vulnerability in southwestern China. Future conservation efforts should be focused on species with habitat contraction, narrow-ranged distribution and endemicity with both in situ and ex situ measures, especially in protected areas. Commercialised collecting targeting these species must also be regulated by future legislation.

Abstract
Objective: To observe the effect of surgical procedures and general anesthesia exposure (<2 h) in early childhood on neurodevelopmental outcomes in school-age. Methods: A total of 147 children aged 6-12 years old, who received surgery under general anesthesia (<2 h) at the age of 0-2 years in Children's Hospital of Nanjing Medical Universityfrom June 2009 to December 2012 were retrospectively enrolled in this study (from June 2018 to December 2021) as exposure group, including 76 males and 71 females, with a mean age of (8.8±1.6) years. All the cases were divided into single-exposure group (n=65) and multiple-exposure group (≥2 times, n=82) according to different times of anesthesia exposure. According to the cohort of exposure group, 160 healthy children of the same age with no history of surgery under general anesthesia were recruited from the community from June 2018 to December 2021 as the control group, including 87 males and 73 females, and aged (8.6±1.9) years. A variety of standardized neurological tests including Wechsler intelligence scale for children fourth edition (WSC-Ⅳ), integrated visual and auditory continuous performance test (IVA-CPT), Swanson Nolan and Pelham, version Ⅳ (SNAP-Ⅳ), children sensory integration capacity development rating scale (CSIC), and social living ability scale were performed in all subjects by a child health specialist who failed to know the details. The primary outcome was the full-scale IQ (FSIQ) in WISC-Ⅳ, and the secondary outcomes were IVA-CPT, SNAP-Ⅳ, CSIC, and social living ability scale. Results: The FSIQ of single-exposure, multiple-exposure and control groups was 105.4±14.1, 100.9±10.2 and 103.6±13.5, respectively, with no statistically significant difference (F=2.37, P=0.095). The FSIQ of different first age exposure groups (aged 0-6 months, 7-12 months and 1-2 years) was 99.8±10.2, 104.5±10.5 and 104.4±14.5, respectively, with no statistically significant difference (F=2.39, P=0.095). The FSIQ of different exposure duration groups (0-59 min, 60-119 min and control group) was 102.8±11.3, 103.0±13.7 and 103.6±13.5, respectively, with no statistically significant difference (F=0.13, P=0.882). As for the secondary outcomes, the scores of visual persistence quotient in single-exposure, multiple-exposure and control groups were 94.8±10.5, 94.0±10.9 and 100.6±17.7, with a statistically significant difference (F=6.96, P=0.001). In terms of locomotion in social living ability scale, the score of the three groups was 10.0±0.2, 10.2±0.6 and 10.4±0.7, respectively, with a statistically significant difference (F=10.61, P<0.001), but all were within the standard range. Conclusions: The surgical procedures and general anesthesia exposure within 2 hours in early childhood has no effect on the overall FSIQ in school age, but has a slight impacts on the visual persistence quotient of IVA-CPT and the locomotion score of social living ability scale.

Abstract
Objective: To investigate the clinical effects of one-stage revision combined with intra-articular infusion of vancomycin in the treatment of chronic prosthetic joint infection (PJI) caused by Enterococcal. Methods: From May 2013 to June 2020,the clinical data of 9 patients (2 males and 7 females) with chronic Enterococcal PJI treated with one-stage revision using intra-articular infusion of vancomycin at Department of Orthopaedics,First Affiliated Hospital of Xinjiang Medical University were retrospectively analyzed,including 8 hips and 1 knee.A total of 9 patients with age of (63.9±11.7)years (range:43 to 76 years) were included, and the body mass index was (23.6±4.3)kg/m2 (range:18 to 30 kg/m2).There were 6 cases with antibiotic history and 5 cases with sinus tract.The joint fluid,infected tissue around the prosthesis and ultrasonic shock fluid of the prosthesis were collected during operation for microbial culture identification and drug sensitivity test.After thorough debridement of the infected site and removal of the infected prosthesis,a new prosthesis was implanted,then the drainage tube in the operation area was placed.After surgery,vancomycin(1.0 g,q12 h) was combined with intra-articular vancomycin(0.5 g,qd) in monomicrobial PJI,and vancomycin(1.0 g,q12 h) was combined with intra-articular vancomycin (0.5 g,qd) and imipenem/meropenem (0.5 g,qd),and the interval between the two drugs was 12 hours in polymicrobial PJI.Hip and knee functions were evaluated by Harris Hip Score or Knee Society Score(KSS),respectively.The comparison of hip function scores before and after operation was performed by paired t-test. Results: All patients were followed up for (60±39)months(range:24 to 110 months).Two cases were infected with Enterococcus faecium and 7 cases were infected with Enterococcus faecalis.There were 7 cases of monomicrobial infection and 2 cases of polymicrobial infection.Erythromycin(5/9),tetracycline(4/9),ciprofloxacin and β-lactam antibiotics(3/9) were the top three antibiotics in Enterococci resistance rate.The sensitive antibiotics for Enterococcal were vancomycin,linezolid and tigecycline.The average duration of intravenous antibiotics was (14±1)days (range:13 to 17 days),and the average duration of antibiotics in articular cavity was (15±2)days(range:11 to 20 days).Mean duration of oral antibiotic use after discharge was (2±1)months(range:1 to 3 months).One case of polymicrobial PJI treatment failed,with a failure rate of 1/9.At last follow-up,the Harris score of patients with hip PJI increased from (43±6)points to (84±6)points(t=-11.899, P<0.01). KSS score of knee function was improved from 33 point pre-operatively to 85 point post-operatively;overall function score was improved from 35 point pre-operatively to 80 point post-operatively.During the treatment,no formation of sinus tract of the hip joint caused by a catheter,skin necrosis at the knee puncture site or leakage of joint fluid;no complications such as deep vein thrombosis and pulmonary embolism occurred. Conclusions: One-stage revision combined with intra-articular infusion of vancomycin can achieve acceptable infection control rate and joint function in patients with chronic Enterococcus PJI.However,the treatment of polymicrobial PJI still needs to be further verified.

Methods: A retrospective cohort study was conducted to include 4 318 patients with early breast cancer who received adjuvant endocrine therapy in Department of Breast Surgery, Peking Union Medical College Hospital from January 1, 2013 to December 31, 2021. All the patients were female, aged (51.2±11.3) years (range: 20 to 87 years), including 1 182 patients in the anastrozole group, 592 patients in the letrozole group, 332 patients in the exemestane group, and 2 212 patients in the toremifene group. The mixed effect model was used to analyze and compare the liver function levels of patients at baseline, 6, 12, 18, 24, 36, 48, 60 months of medication, and 1 year after drug withdrawal among the three aromatase inhibitors (anastrozole, letrozole, exemestane) and toremifene. Results: ALT and AST of the 4 groups were significantly higher than the baseline level at 6 months (all P<0.01), and there were no significant differences in total bilirubin, direct bilirubin and AST levels among all groups one year after drug withdrawal (P: 0.538, 0.718, 0.061, respectively). There was no significant difference in the effect of all groups on AST levels (F=2.474, P=0.061), and in the effect of three aromatase inhibitors (anastrozole, letrozole, and exemestane) on ALT levels (anastrozole vs. letrozole, P=0.182; anastrozole vs. exemestane, P=0.535; letrozole vs. exemestane, P=0.862). Anastrozole and letrozole had significantly higher effects on ALT levels than toremifene (P<0.01, P=0.009). The proportion of abnormal liver function in each group increased significantly at 6 months compared with baseline, and then the proportion showed a decreasing trend over time. Conclusions: Three aromatase inhibitors (anastrozole, letrozole, and exemestane) and toremifene can significantly increase the level of ALT and AST in patients with breast cancer, and the levels can gradually recover to the baseline after 1 year of drug withdrawal. The effect of non-steroidal aromatase inhibitors (anastrozole, letrozole) on ALT levels is greater than toremifene.

Abstract
Background and aims Nonalcoholic fatty liver disease (NAFLD) is the most common type of chronic liver disease with a high incidence, and the situation is not optimistic. Intestinal flora imbalance is strongly correlated with NAFLD pathogenesis. Zhishi Daozhi Decoction (ZDD) is a water decoction of the herbs used in the classical Chinese medicine prescription Zhishi Daozhi Pills. Zhishi Daozhi Pills has shown promising hepatoprotective and hypolipidemic properties, but its specific mechanism remains unclear. Methods Mice were fed on a high fat-rich diet (HFD) for ten weeks, and then the animals were administrated ZDD through oral gavage for four weeks. The serum liver function and blood lipid indexes of the mice were then tested using an automatic biochemical analyzer. H&E and Oil Red O staining were used to observe the pathological conditions of mice liver tissue, and 16S rRNA sequencing technology was used to analyze the changes in intestinal flora of mice. The concentration of short-chain fatty acids (SCFAs) in the gut of mice was analyzed by gas chromatography-mass spectrometry (GC-MS). The expression of tight junction (TJ) proteins between ileal mucosal epithelial cells was analyzed using the immunofluorescence technique. Results ZDD was found to reduce the bodyweight of NAFLD mice, reduce serum TG, CHO, ALT, and AST levels, reduce fat accumulation in liver tissue, make the structure of intestinal flora comparable to the control group, and increase the concentration of intestinal SCFAs. It was also found to increase the expression of TJ proteins such as occludin and ZO-1, making them comparable to the control group. Conclusions ZDD has a therapeutic effect on NAFLD mice induced by HFD, which may act by optimizing the intestinal flora structure.

Abstract
Objective: To investigate the clinical efficacy of liver transplantation in the treatment of acute liver in children with NBAS gene deficiency disease and their outcome. Methods: This retrospective study enrolled children with NBAS gene deficiency who were admitted to the Children's Hospital of Fudan University for liver transplantation from January 2013 to June 2022. The clinical data were collected and analyzed. Medical literature published before June 2022 was searched with the keywords of "NBAS" "neuroblastoma amplified sequence recurrent" "acute liver failure" "SOPH syndrome" "short stature with optic nerve atrophy" "Pelger-Huët anomaly" in PubMed, China National Knowledge Infrastructure and Wanfang database. Results: Liver transplantation was performed in 3 patients (2 males and 1 female) with NBAS deficiency. All patients presented with fever-triggered recurrent acute liver failure. The genetic detection found compound heterozygous NBAS gene pathogenic variants in them. The total episodes of acute liver failure before liver transplantation were 11, 2, and 4 respectively, and the age at liver transplantation was 3.5, 2.3, and 2.0 years respectively. During liver transplantation, patient 1 was in the convalescent phase of acute liver failure, patient 2 was in the acute phase, presenting with hepatic encephalopathy (grade V) and respiratory failure, and patient 3 was considered to be in the acute phase. After liver transplantation, patient 1 recovered normal liver function within 1 month and had no liver transplantation-related complications. Patient 2 had secondary epilepsy, intellectual disability, movement disorder, and transiently elevated transaminases. Patient 3 died of severe infection within 1 month. There was no literature in Chinese, 6 in English, 8 NBAS-deficient patients who were treated with liver transplantation. Total 11 patients presented with fever-triggered recurrent acute liver failure. Their age at liver transplantation ranged from 0.9 to 5.0 years. Postoperative complications occurred in 3 patients. Until the last visit, they were followed up for 0.7 to 14.0 years. Total 2 patients died and the 9 surviving patients did not develop acute liver failure. Conclusions: Liver transplantation is effective for the treatment of acute liver failure associated with NBAS gene disease. However, postoperative complications of liver transplantation may occur. The timing of liver transplantation still needs further research.

Abstract
Objective: To investigate the clinical prognostic value of dynamic minimal residual disease (MRD) after autologous hematopoietic stem cell transplantation (AHSCT) in patients with multiple myeloma (MM). Methods: Patients with MM who underwent AHSCT in Beijing Chao-Yang Hospital from February 2016 to December 2019 were enrolled in this study. All the patients in the study had complete baseline data at the diagnosis. AHSCT was performed after induction chemotherapy. Response evaluation was performed after induction therapy. All the patients were assessed at approximately 100 days after AHSCT. Bone marrow MRD by NGF was performed every three months and dynamically monitored for at least 12 months. All the patients were divided into different groups according to cytogenetics and MRD status. Survivals in different groups were analyzed by IBM SPSS 22.0 statistical software. Results: A total of 150 patients with MM were enrolled in this study at last, including 66 patients in the cytogenetic standard risk group and 84 patients in the cytogenetic high-risk group. The median age was 54 years (range 30-68 years) and 87 male patients (58.0%) was in the study. The median follow-up was 36 months (range 16-72 months). Patients in the standard-risk group had better clinical prognosis than those in the high-risk group [median PFS in the standard-risk group was not achieved, and median PFS in the high-risk group was 45 months (P<0.001); median OS of both groups was not reached, and the estimated 3-year OS rate of the standard-risk group and the high-risk group was 95.2% and 78.9%, respectively (P=0.001)]. According to MRD status of patients, patients in each group were divided into three subgroups: persistent positive (Ppos), transient negative (Tneg) and persistent negative (Pneg). The median OS and median PFS of all subgroups in the standard-risk group was not reached (P=0.324 and P=0.086). In high-risk group, the median OS of MRD Pneg subgroup was not reached, and the estimated 3-year OS rate was 100%; The median OS of MRD Ppos subgroup was 52 months, and MRD Tneg subgroup only 31 months (P=0.002); the median PFS of MRD Pneg group was not reached, and the estimated 3-year PFS rate was 85.4%; median PFS of MRD Ppos subgroup was 40 months, and MRD Tneg subgroup only 17 months (P=0.001). Conclusions: MRD Pneg might overcome the adverse prognosis of MM patients with high-risk cytogenetics. However, MRD Tneg might be a poor prognostic factor for the patients with cytogenetic high-risk MM.

Abstract
The oral cavity is the second largest microbial habitat in the whole body. Due to the divergence of oxygen, metabolic substrates and rate-limiting enzymes, oral bacteria are classified into sugar-metabolizing and nitrogen-compound-metabolizing bacteria according to their metabolic characteristics. The metabolites include organic acids, carbon dioxide, amino acids, proteins, and ammonia. Oral bacterial metabolites are very important for oral bacteria growth and reproduction, and also play an important role in systemic diseases such as periodontitis, oral cancer, intestinal diseases, diabetes and atherosclerosis. Therefore, in-depth exploration of oral bacterial metabolism is of great significance to understand the impact of oral cavity on systemic health. This article reviews the metabolic characteristics of oral bacteria and their correlation with systemic diseases.

Abstract
β-Ga2O3 is considered an attractive candidate for next-generation high-power electronics due to its large band gap of 4.9 eV and high breakdown electrical field of 8 MV/cm. However, the relatively low carrier concentration and low electron mobility in the β-Ga2O3-based device limit its application. Herein, the high-quality β-Ga2O3 single crystal with high doping concentration of ∼3.2 × 1019 cm-3 was realized using an optical float-zone method through Ta doping. In contrast to the SiO2/β-Ga2O3 gate stack structure, we used hexagonal boron nitride as the gate insulator, which is sufficient to suppress the metal-insulator-semiconductor (MIS) interface defects of the β-Ga2O3-based MIS field-effect transistors (FETs), exhibiting outstanding performances with a low specific on-resistance of ∼6.3 mΩ·cm2, a high current on/off ratio of ∼108, and a high mobility of ∼91.0 cm2/(V s). Our findings offer a unique perspective to fabricate high-performance β-Ga2O3 FETs for next-generation high-power nanoelectronic applications.

Abstract
The superior optical and electronic characteristics of quasi-two-dimensional β-Ga2O3 make it suitable for solar-blind (200-280 nm) photodetectors (PDs). The metal-semiconductor-metal (MSM) PDs commonly suffer from low photoresponsivity, slow response speed, and a narrow detection wavelength range despite their simple fabrication process. Herein, we report a high-performance MSM PD by integrating exfoliated β-Ga2O3 flakes with zero-dimensional graphene quantum dots (GQDs), which exhibits the advantages of enhancing the photoresponsivity, shortening the photoresponse time, and stimulating a broad range of photon detection. The hybrid GQDs/β-Ga2O3 heterostructure PD is sensitive to deep-ultraviolet (DUV) light (250 nm) with an ultrahigh responsivity (R of ∼2.4 × 105 A/W), a large detectivity (D* of ∼4.3 × 1013 Jones), an excellent external quantum efficiency (EQE of ∼1.2 × 108%), and a fast photoresponse (150 ms), which is superior to the bare β-Ga2O3 PD. These improvements result from effective charge transfer due to the introduction of GQDs, which enhance the light absorption and the generation of electron-hole pairs. In addition, the hybrid GQDs/β-Ga2O3 PD also exhibits better photoelectric performance than the bare β-Ga2O3 PD at a 1000 nm wavelength. As a conclusion, the hybrid GQDs/β-Ga2O3 DUV photodetector shows potential applications in commercial optoelectronic products and provides an alternative solution for the design and preparation of high-performance photodetectors.

Abstract
Objective: To assess the association between short-term exposure level of nitrogen dioxide and the hospitalization risk of heart failure. Methods: Based on China-PEACE Retrospective Heart Failure Study, 117 364 hospitalized patients with heart failure were recruited from 92 hospitals in 62 cities throughout China between January 1, 2015 and December 31, 2015. The daily exposure level of nitrogen dioxide, temperature, and humidity in the same cities during the same period were also collected. We applied the generalized additive model and Bayesian hierarchical model to quantify the lagged effect and cumulative effect of short-term (0-3 days) exposure to ambient nitrogen dioxide on the hospitalization risk of heart failure. We further conducted stratified analyses by age, region, and season to identify any difference in the associations between short-term nitrogen dioxide exposure and heart failure among subgroups. Results: The mean age for participants in the analysis was (70.32±12.22) years. The median, minimum and maximum of daily nitrogen dioxide concentration in 62 cities from January 1, 2015 to December 31, 2015 was 26.4 μg/m3, 2.33 μg/m3 and 150.25 μg/m3, respectively. The exposure level of nitrogen dioxide at the same day was associated with the hospitalization risk of heart failure (OR=1.022, 95%CI: 1.012, 1.031). Significant effects were also observed in the moving average concentrations from lag 0-1 to lag 0-3 day (OR=1.020, 95%CI: 1.009, 1.030; OR=1.016, 95%CI: 1.004, 1.028; OR=1.013, 95%CI: 1.001, 1.026). Moreover, all of the associations between short-term exposure to nitrogen dioxide and the risk of heart failure hospitalization were statistically significant, with no significant difference in all subgroups stratified by age, region, and season. Conclusion: A higher level of short-term exposure to nitrogen dioxide could trigger more hospitalizations with heart failure.

Objective: To investigate the effects of continuous goal-directed analgesia on fluid resuscitation during shock stage in patients with massive burns, providing a basis for rational optimization of analgesia protocols in patients with burn shock. Methods: A retrospective case series study was conducted. One hundred and thirty-six patients with massive burns who met the inclusion criteria were admitted to Zhengzhou First People's Hospital from January 2015 to December 2020, and the patients were divided into continuous analgesia (CA) group (68 cases,with average age of 44 years old) and intermittent analgesia (IA) group (68 cases,with average age of 45 years old) according to whether sufentanil injection was continuously used for intravenous analgesia during the shock stage. The patients in the 2 groups were predominantly male. Before and at 72 h of treatment, the severity of disease and trauma pain of patients in the 2 groups were scored by the acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) and the visual analogue scale (VAS). Hematocrit, heart rate, mean arterial pressure (MAP), central venous pressure (CVP), oxygen saturation in central venous blood (ScvO2), rehydration coefficient, blood lactate value, hourly urine output, and the adverse reactions such as hypotension, nausea, vomiting, dizziness, skeletal muscle tonicity, respiratory depression, bradycardia, pruritus, and drug addiction of patients in the 2 groups during the treatment were recorded at the 1st, 2nd, and 3rd 24 h post-injury. Data were statistically analyzed with analysis of variance for repeated measurement, paired or independent sample t test, Bonferroni correction,chi-square test and Mann-Whitney U test. Results: Before treatment, APACHE Ⅱ and VAS scores of patients in the 2 groups were close (with t values of -0.67 and 0.32, respectively, P>0.05); At 72 h of treatment, APACHE Ⅱ and VAS scores of patients in CA group were 8.5±2.2 and 2.5±1.6, both of which were significantly lower than (15.2±3.0) and (7.9±2.0) of patients in IA group, respectively (with t values of -14.94 and -17.46, respectively, P<0.01). Compared with the pre-treatment period, the APACHE Ⅱ and VAS scores of patients in IA group decreased significantly at 72 h of treatment (with t values of 11.35 and 30.59, respectively, P<0.01); the changes in APACHE Ⅱ and VAS scores of patients at 72 h of treatment in comparison with those of patients before treatment in CA group were all similar to those of patients in IA group (with t values of 4.00 and 4.82, respectively, P<0.01). Compared with those of patients in IA group, there were no significant changes in CVP, hematocrit, heart rate, ScvO2, and MAP of patients in CA group at all three 24 h post-injury (with t values of <0.01, 0.12, 2.10, 1.55, 0.03; 0.13, 0.22, <0.01, 0.17, 0.49; 0.63, 0.06, 0.04, 2.79, and 2.33, respectively, P>0.05). Compared with those of patients in IA group at the 1st 24 h post-injury, CVP, ScvO2 and MAP of patients were significantly higher at the 2nd and 3rd 24 h post-injury (with t values of -10.10, -9.31, -8.89; -10.81, -4.65, and -9.43, respectively, P<0.01), and the heart rate of patients was significantly lower at the 2nd and 3rd 24 h post-injury (with t values of 7.53 and 7.78, respectively, P<0.01), and the hematocrit of patients decreased significantly only at the 3rd 24 h post-injury (t=15.55, P<0.01); the changes of CVP, ScvO2, MAP and heart rate of patients at the 2nd and the 3rd 24 h post-injury, and HCT of patients at the 3rd 24 h post-injury, in comparison with those of patients at the 1st 24 h post-injury in CA group were similar to those of patients in IA group (with t values of -12.25, -10.24, -8.99, 9.42, -8.83, -7.53, -11.57, 10.44, and 12.91, respectively, P<0.01). Compared with those of patients in IA group, the rehydration coefficient of patients in CA group was significantly higher only at the 3rd 24 h post-injury (t=5.60, P<0.05), blood lactate value of patients in CA group was significantly lower at the 1st and 2nd 24 h post-injury (with t values of 4.32 and 14.52, respectively, P<0.05 or P<0.01), the hourly urine output of patients in CA group increased significantly at the 1st, 2nd, and 3rd 24 h post-injury (with t values of 24.65, 13.12, and 5.63, respectively, P<0.05 or P<0.01). Compared with the those of patients at the 1st 24 h post-injury, the rehydration coefficient of patients in IA group decreased significantly at the 2nd and the 3rd 24 h post-injury (with t values of 33.98 and 36.91, respectively, P<0.01), the blood lactate values of patients in IA group decreased significantly at the 2nd and the 3rd 24 h post-injury (with t values of 8.20 and 11.68, respectively, P<0.01), and the hourly urine output of patients in IA group was significantly increased at the 2nd and the 3rd 24 h post-injury (with t values of -3.52 and -5.92, respectively, P<0.01); the changes of rehydration coefficients and blood lactate values of patients at the 2nd and the 3rd 24 h post-injury in comparison with those of patients at the 1st 24 h post-injury in CA group were similar to those of patients in IA group (with t values of 35.64, 33.64, 9.86, and 12.56, respectively, P<0.01), but hourly urine output of patients in CA group increased significantly only at the 3rd 24 h compared with that of patients at the 1st 24 h post-injury (t=-3.07, P<0.01). Adverse reactions such as hypotension, nausea, vomiting, dizziness, bradycardia, and pruritus occurred rarely in patients of the 2 groups, and none of the patients had skeletal muscle tonicity, respiratory depression, or drug addiction. The incidence of adverse reactions of patients in CA group was similar to that in IA group (χ2=0.08, P>0.05). Conclusions: Continuous goal-directed analgesia can effectively relieve pain and improve vital signs of patients with large burns. Meanwhile it has little impact on volume load, which can assist in correcting ischemia and hypoxia during the shock period and help patients get through the shock period smoothly.

Abstract
A high optoelectronic performance ReS2/ReSe2 van der Waals (vdW) heterojunction phototransistor utilizing thin hafnium oxide (HfO2) as a local-back-gate dielectric layer was prepared and studied. The heterojunction-based phototransistor exhibits a superior electrical performance with a large rectification ratio of ∼103. Furthermore, unlike diode-like heterojunction devices, the innovative introduction of a local-back-gate in this phototransistor provides an outstanding gate-tunable capability with an ultra-low off-state current of 433 fA and a high on/off current ratio of over 106. And under optical excitation of a wide spectrum from 400 to 633 nm, an excellent photodetection responsivity at the 104 A W-1 level and the maximum normalized detectivity of 1.8 × 1015 Jones @ 633 nm have been demonstrated. Such high performances are attributed to the band alignment of the type-II heterojunction and the suppression of dark current by the local-back-gate. This work provides a promising reference for two-dimensional (2D) Re-based heterojunction optoelectronic devices.

Abstract
Objective: To investigate the clinical effects of medical ozone autologous blood transfusion combined with Xingnaojing in the treatment of septic encephalopathy in burns. Methods: The retrospective cohort study was conducted. From August 2015 to May 2019, 90 patients with burn septic encephalopathy and conforming to the inclusion criteria were admitted to Zhengzhou First People's Hospital. Forty-six patients (25 males and 21 females, aged (35±4) years ) treated with Xingnaojing were included in Xingnaojing alone group, and forty-four patients (20 males and 24 females, aged (34±5) years) treated with medical ozone autologous blood transfusion combined with Xingnaojing were included in ozone autologous blood transfusion+Xingnaojing group. Heart rate, body temperature, mean arterial pressure, acute physiology and chronic health evaluation Ⅱ(APACHEⅡ) score and Glasgow coma score (GCS) of patients in 2 groups were recorded before treatment and on 7 d after treatment. The blood-brain barrier injury markers including occludin, nitric oxide synthase (NOS), neuron-specific enolase (NSE), central nervous system specific protein S100β, glial fibrillar acidic protein (GFAP), and excitatory amino acid (EAA) in serum of patients in 2 groups were detected before treatment and on 1, 3, and 7 d after treatment. Computer tomography perfusion imaging for brain was performed in patients of 2 groups to calculate the region of interest cerebral blood flow (rCBF), region of interest blood volume (rCBV), and region of interest mean transit time (rMTT) before treatment and on 1, 3, and 7 d after treatment. Data were statistically analyzed with chi-square test, analysis of variance for repeated measurement, independent sample t test, and Bonferroni correction. Results: On 7 d after treatment, heart rate, body temperature, and mean arterial pressure of patients in 2 groups were decreased compared with those before treatment, heart rate of patients in ozone autologous blood transfusion+Xingnaojing group was obviously higher than that in Xingnaojing alone group (t=2.886, P<0.01), body temperature of patients in ozone autologous blood transfusion+Xingnaojing group was obviously lower than that in Xingnaojing alone group (t=5.020, P<0.01), and mean arterial pressure of patients in 2 groups were close (t=0.472, P>0.05). On 7 d after treatment, APACHEⅡ score of patients in ozone autologous blood transfusion+Xingnaojing group was obviously lower than that in Xingnaojing alone group (t=3.797, P<0.01), and GCS of patients in ozone autologous blood transfusion+Xingnaojing group was obviously higher than that in Xingnaojing alone group (t=4.934, P<0.01). On 3 and 7 d after treatment, the levels of occludin, NOS, NSE, S100β, GFAP, and EAA in serum of patients in ozone autologous blood transfusion+Xingnaojing group were significantly lower than those in Xingnaojing alone group (t=2.100, 2.090, 2.691, 2.013, 2.474, 2.635, 2.225, 4.011, 3.150, 2.691, 3.145, 2.781, P<0.05 or P<0.01). On 1, 3, and 7 d after treatment, rCBF and rCBV of patients in ozone autologous blood transfusion+Xingnaojing group were significantly increased compared with those in Xingnaojing alone group (t=3.127, 3.244, 3.883, 7.274, 3.661, 2.777, P<0.01). On 7 d after treatment, rMTT of patients in ozone autologous blood transfusion+Xingnaojing group was (3.02±0.57) s, which was significantly lower than (3.11±1.20) s in Xingnaojing alone group (t=2.409, P<0.05). Conclusions: Transfusion of medical ozone autologous blood combined with Xingnaojing therapy can effectively relieve brain injury and improve cerebral blood perfusion in patients with burn septic encephalopathy, which is with safety and credibility.

Abstract
Objective: To evaluate the levels of alveolar bone defects by using cone-beam CT in periodontitis patients with history of orthodontic treatment and to find the special tooth positions, sites and periodontitis stages of alveolar bone defects, so as to provide reference for the formulation of clinical personalized diagnosis and treatment plans. Methods: Thirty patients who were diagnosed as Angle class Ⅱ malocclusion, treated by using labial fixed orthodontic appliances and also diagnosed as periodontitis (orthodontic group) were recuited from January 2009 to June 2019 at the School and Hospital of Stomatology, China Medical University in the present study. They were aged (27.0±5.4) years old (ranged 18-41 years old). Another 60 periodontitis patients without a history of orthodontic treatment matched according to age, gender and severity of periodontitis were selected as control group (non-orthodontic group). They were aged (26.7±5.2) years old (ranged 18-41 years old). Cone-beam CT images were used to measure the heights of the alveolar bone defects at each tooth position of the patients. The difference in the heights of the alveolar bone defects between the orthodontic group and the non-orthodontic group at the same position of the maxillary and mandibular alveolar bones were compared. The specificities of the defect heights in different positions of the maxillary and mandibular alveolar bones and different sites of the same tooth position were analyzed among orthodontic group. The specificities of the different tooth positions of the maxillary and mandibular alveolar bones of the different periodontitis stages among orthodontic group were compared. Results: The heights of the alveolar bone defects in the maxillary canine area and molar area, the mandibular incisor area, the canine area and the premolar area in the orthodontic group were higher than that in the non-orthodontic group, and the differences were statistically significant (P<0.05). In orthodontic group, the most severe teeth in the maxillary and mandibular alveolar bone defects were the canine areas [(3.75±1.00), (3.83±1.10) mm]. Secondly, the more severe tooth positions of the maxillary alveolar bone height defects were the molar area [(3.67±0.84) mm] and the incisor area [(3.39±0.83) mm] and the more severe tooth positions of the mandibular alveolar bone defects were the incisor area [(3.73±1.42) mm] and the molar area [(3.54±0.81) mm]. The height of the alveolar bone defect in the mandibular incisor area was greater than that in the maxillary (P<0.05). The bone defect in the maxillary molar area was severer than that of the mandibular area (P<0.05). The alveolar bone defects in the buccal and lingual sides were mostly larger than that of the mesial and distal sides both in maxillary and mandibular positions except for the maxillary incisor area(P<0.05). The most severe alveolar bone defect position changed with the periodontitis stage. The most severe tooth position of the maxillary in stage Ⅰ periodontitis was in the molar area [(3.26±0.63) mm], whereas the incisor area was the most severe tooth of the mandible [(3.14±1.04) mm]. In addition, among maxillary incisor area, canine area, premolar area, molar area, the most severe alveolar bone defect height was the canine area in stage Ⅱ, Ⅲ, Ⅳ mandibular (P<0.05). Conclusions: In periodontitis patients with a history of orthodontic treatment, the height of the alveolar bone defect was specific to the tooth positions and sites. With the periodontitis stage changing, the most severe defect position changed in both maxillary and mandibular alveolar bones. It is recommended to pay more attention to the alteration of alveolar bone in periodontitis patients with a history of orthodontic treatment and give timely targeted treatment plans.

Abstract
OBJECTIVE The present study is to characterize the role of long intergenic non-coding RNA, regulator of reprogramming (linc-ROR) in bone marrow mesenchymal stem cell (BMSCs) chondrogenesis, cartilage formation and OA development. METHODS Linc-ROR expression pattern in articular cartilage tissue sample from OA patients were studied by real-time PCR. Linc-ROR lentivirus mediated BMSCs were constructed. In vitro micromass cultured BMSCs chondrogenesis or in vivo MeHA hydrogel encapsulated BMSCs cartilage formation activity were studied. Linc-ROR associating miRNAs which repressed SOX9 expression were characterized by luciferase assay, real-time PCR and Western blot. Linc-ROR was co-transfected with miRNAs into BMSCs to study its rescue effect on SOX9 expression and chondrogenesis activity. RESULTS Linc-ROR was down-regulated in articular cartilage tissue from OA patients and was positively correlated with the expression level of SOX9 (R2 = 0.43). Linc-ROR expression was upregulated during BMSCs chondrogenesis. Linc-ROR ectopic expression significantly promoted in vitro BMSCs chondrogenesis and in vivo cartilage formation activities as revealed by safranin O, alcian blue and COL II staining. The mRNA expression level of chondrogenesis markers including COL II, SOX9 and ACAN were increased, and the hypertrophy markers MMP13 and COL X were decreased upon linc-ROR overexpression in BMSCs. Linc-ROR functioned as a miRNA sponge for miR-138 and miR-145. Both miR-138 and miR-145 suppressed BMSCs chondrogenesis activity and SOX9 expression, while co-expression of linc-ROR displayed a rescuing effect. CONCLUSIONS Taken together, linc-ROR modulated BMSCs chondrogenesis differentiation and cartilage formation by acting as a competing endogenous RNA for miR-138 and miR-145 and activating SOX9 expression. Linc-ROR could be considered as a new diagnostic and therapeutic target for OA treatment.

Abstract
The impurity radiation from the divertor region of the EAST tokamak is dominantly in the wavelength range of vacuum ultraviolet (VUV) due to the elevated edge electron temperature. A space-resolved VUV spectroscopy is developed to measure impurity radiation in the divertor region. An eagle-type VUV spectrometer with a focal length of 1 m is adopted in this system, equipped with a spherical grating and a charged-coupled device (CCD) detector. The performance of the VUV spectrometer is preliminarily tested on a synchrotron radiation facility. The wavelength calibration is conducted near 65 nm. It is found that the wavelength range observed by the CCD detector is about 11.07 nm around the central wavelength of about 65 nm. With a linear dispersion of 0.0053 nm/pixel, it is possible to measure the ion temperature lower than 20 eV at the edge region by analyzing the Doppler broadening of a carbon line. These test results show that the performance of the VUV spectrometer is capable of measuring divertor radiation and analyzing the ion temperature of edge impurity ions.

Abstract
An asymmetric dual-gate (DG) MoS2field-effect transistor (FET) with ultrahigh electrical performance and optical responsivity using atomic-layer-deposited HfO2as a top-gate (TG) dielectric was fabricated and investigated. The effective DG modulation of the MoS2FET exhibited an outstanding electrical performance with a high on/off current ratio of 6 × 108. Furthermore, a large threshold voltage modulation could be obtained from -20.5 to -39.3 V as a function of the TG voltage in a DG MoS2phototransistor. Meanwhile, the optical properties were systematically explored under a series of gate biases and illuminated optical power under 550 nm laser illumination. An ultrahigh photoresponsivity of 2.04 × 105AW-1has been demonstrated with the structure of a DG MoS2phototransistor because the electric field formed by the DG can separate photogenerated electrons and holes efficiently. Thus, the DG design for 2D materials with ultrahigh photoresponsivity provides a promising opportunity for the application of optoelectronic devices.

Abstract
Objective: To study the efficacy and patient comfort of absorbable hemostatic powder after endoscopic sinus surgery (ESS). Methods: A total of 21 (17 males, 4 females) patients with an average age of 42(ranging from 18 to 65) underwent bilateral ESS for chronic rhinosinusitis(CRS) in Beijing Tongren Hospital, Capital Medical University between October 2015 and July 2019 were enrolled to compare the effect of absorbable hemostasis powder with Nasopore using an intrapatient control design. A randomized controlled trial was conducted in the left and right nasal cavities of the same patient. If hemostatic powder was applied in the experiment nasal cavity, the Nasopore was applied in the control nasal cavity. The mean preoperative sinus computed tomography (CT) score was 6.25. All patients competed for symptom diaries using a visual analog scale (VAS, score out of 10) at baseline, through 1, 7, 14 and 30 days. Outcomes including bleeding, facial pain, nasal obstruction, nasal discharges using VAS were recorded separately for both sides. Postoperative endoscopic scores were also investigated. SPSS 22 and Graphpad prism 8.0 statistical softwares were used for the analysis. Paired t-test or nonparametric test was used between the test side and the control side. The difference was statistically significant (P<0.05). Results: The bleeding score and total nasal symptom VAS scores at postoperative days (POD) 1, 7, 14 and 30 were not significantly different(t=1.341, 0.552, 0.631, 0.158, all P>0.05;t=0.944, 1.471, 1.612, 2.251, all P>0.05). There was no significant difference between absorbable hemostasis powder and Nasopore side on POD 1, 7, 14 and 30 in terms of each nasal symptom VAS scores(all P>0.05). On POD 1, 7 and 14, the packing material degeneration scores of the absorbable hemostasis powder side were significantly lower than those of the Nasopore side [(1.33±0.21)vs(2.00±0.00),(0.38±0.18) vs (1.95±0.22), 0 vs (1.80±0.13), all P<0.01]. There were significant differences between absorbable hemostasis powder and Nasopore side on POD 1, 7, 14 and 30 in terms of endoscopic scores (edema, crusting, discharges, scar, polyps and material degeneration, t=3.07, 7.00, 6.41, 2.69, all P<0.05). Conclusions: The absorbable hemostasis powder and Nasopore has similar postoperative hemostasis effect. The absorbable hemostasis powder is rapidly cleared and without negative effects on mucosal wound healing 14 days postoperatively.

Abstract
With a population of around 4 000 individuals, the Kalash people have been living in the Hindu-Kush mountain valleys of present-day northern Pakistan for centuries. Due to their mysterious origin and fairer European complexion, the genetic history of this ethnic group has been investigated previously using different markers. To date, however, the maternal genetic architecture has not been systematically dissected based on high-resolution complete mitochondrial genomes (mitogenomes), making their maternal genetic history, especially their genetic connection with Europeans from a matrilineal perspective, unclear. To unravel this issue, we analyzed mitogenome data of 34 Kalash samples together with 6 075 individuals from across Eurasia. Our results indicated exclusive western Eurasian origin of the Kalash people, represented by eight haplogroups. Among these haplogroups, J2b1a7a and R0a5a (accounting for ~50% of the Kalash gene pool) displayed in situ differentiations in the Kalash and could be traced to the Mediterranean region. Age estimations suggested these haplogroups arose in the Kalash population ~2.26 and 3.01 thousand years ago (kya), a time frame consistent with the invasion of Alexander III of Macedon to the region. One possible explanation for the maternal genetic contribution from Europeans to the Kalash people would be the involvement of women in foreign campaigns of ancient Greek warfare, followed by a founder effect. Our study thus sheds important light on the genetic origin of the Kalash community of Pakistan.

Abstract
The Fujian Tanka people are officially classified as a southern Han ethnic group, whereas they have customs similar to Daic and Austronesion people. Whether they originated in Han or Daic people, there is no consensus. Three hypotheses have been proposed to explain the origin of this group: (1) the Han Chinese origin, (2) the ancient Daic origin, (3) and the admixture between Daic and Han. This study addressed this issue by analyzing the paternal Y chromosome and maternal mtDNA variation of 62 Fujian Tanka and 25 neighboring Han in Fujian. The southern East Asian predominant haplogroups (e.g., Y-chromosome O1a1a-P203 and O1b1a1a-M95, and mtDNA F2a, M7c1, and F1a1) had relatively high frequencies in Tanka. The interpopulation comparison revealed that the Tanka have a closer affinity with Daic populations than with Han Chinese in paternal lineages but are closely clustered with southern Han populations such as Hakka and Chaoshanese in maternal lineages. Network and haplotype-sharing analyses also support the admixture hypothesis. The Fujian Tanka mainly originate from the ancient indigenous Daic people and have only limited gene flows from Han Chinese populations. Notably, the divergence time inferred by the Tanka-specific haplotypes indicates that the formation of Fujian Tanka was a least 1033.8-1050.6 years before present (the early Northern Song dynasty), indicating that they are an indigenous population, not late Daic migrants from southwestern China.

Abstract
OBJECTIVE To examine the association between the most recent HbA1c values and the mortality of elderly Type 2 Diabetic (T2DM) patients managed in the public primary care setting and to explore the associating risk factors. DESIGN Retrospective cohort study. SUBJECTS All T2DM patients aged 65 or above, who attended a public primary care clinic for regular follow up from 01/01/2012 to 31/12/2012 were included. Their follow up status till 31/12/2017 was reviewed. Those who were deceased on or before 31/12/2017 were matched randomly with controls that were alive in the same cohort for comparison. MAIN OUTCOME MEASURES Patients' demographics, smoking status, duration of T2DM, biochemical parameters including the most recent HbA1c, lipid profile, renal function test, drug profile, co-morbidities and all-cause mortality were retrieved from Hospital Authority's CDARS and CMS systems. RESULTS Both high (>8.0%) and low (<6.5%) HbA1c values were associated with increased odd ratio of all-cause mortality among T2DM elderly patients treated in the primary care. There was a 3-fold increase in odd ratio when the HbA1c reading was very low (<6.0%). Associated risk factors for all-cause mortality in elderly T2DM patients included smoker status, lower BMIs, and higher LDL levels and use of sulphonylureas. CONCLUSIONS Glycemic target for elderly T2DM patients should be approached cautiously. Over-aggressive treatment may lead to increased mortality among elderly T2DM patients.

Abstract
BACKGROUND Chronic obstructive pulmonary disease (COPD) is a progressive lung disease commonly encountered in primary care. This study aimed to audit COPD care at primary care clinics of Hong Kong and to work out improvement strategies. METHOD All COPD patients aged 40 or above who had been followed up at 13 public primary care clinics of Kowloon Central Cluster (KCC) under the Hospital Authority of Hong Kong (HAHK) were included in this clinic audit. Evidence-based audit criteria and performance standards were established after thorough literature review. Phase 1 was from 1st April 2016 to 31st March 2017, with deficiencies of care identified. It was followed by a one-year implementation phase through which a series of improvement strategies were executed. Outcome of the enhancement was reviewed during Phase 2 from 1st April 2018 to 31st March 2019. Chi-square test and student's t test were used to detect statistically significant changes between Phase 1 and Phase 2. RESULTS A total of 2358 COPD cases were identified in Phase 1 where 658 of them were smokers. Of those smokers, 332 (50.5%) had been referred to Smoking Counselling and Cessation Service (SCCS) and 289 (43.9%) actually attended it. 991 cases (42%) received Seasonal Influenza Vaccine (SIV) and 938 cases (39.8%) received Pneumococcal Vaccine (PCV). 698 patients (29.6%) had spirometry done before and 423 patients (17.9%) had been admitted to hospital due to acute exacerbation of COPD (AECOPD). With the concerted effort taken during the implementation phase, Phase 2 data showed significant improvement in nearly all criteria. There was a marked increase in the SIV and PCV uptake rate, spirometry performance rate and most importantly, a significant reduction in AECOPD rate leading to hospital admission (13.5%, P = 0.000043). However, the referral rate and attendance rate of SCCS among smokers remained stagnant (P > 0.05). CONCLUSION Via a systematic team approach, COPD care at primary care clinics of KCC under HAHK had been significantly improved for most of the audit criteria, which in turn reduced the burden of the healthcare system.

Abstract
On March 14, 2017, a thirty years old male severe burn patient accompanied by asphyxia, sudden cardiac arrest, and acute respiratory distress syndrome was admitted to Zhengzhou First People's Hospital. During the shock stage, the pulse contour cardiac output was monitored for the restrictive rehydration, tracheotomy was performed, and fibrobronchoscope lavage was performed for the treatment of inhalation injury and pulmonary infection. An alternate application of suspended bed and turning bed was conducted to balance the treatment of cerebral edema and pulmonary infection; targeted antibiotics were used for anti-infective treatment; multiple operations were performed for eschar excision and skin grafting. At last, the wounds were all healed, the lung infection was cured, and the patient was discharged with severe disturbance of consciousness. Asphyxia and acute respiratory distress syndrome post-cardiopulmonary resuscitation are serious complications in severe burn patients. The clinical treatment of such patients is very difficult and should be highly alerted.

Abstract
The establishment of the Diet and Hygiene Society was based on the starting point of improving the diet and health habits of the Chinese people, and soon it was involved in a broader public health field with the changes of the times. Its purpose was to "improve food, research hygiene and avoid illness, so as to achieve longevity" . The society advocated vegetarianism and set up a vegetarian restaurant. It publicized "cutting queue but not changing clothes into western style" , which set off the trend of queue cutting in Shanghai. It participated in the prevention of plague in Shanghai, which has reconciled the conflict between Chinese people and foreign officials and has promoted the independent quarantine of Chinese. Discouraging people from smoking cigarettes was considered beneficial for keeping healthy and reducing the trade deficit.

Abstract
In this study, a virtual-reality (VR) pedestrian simulation method was used to evaluate the risks to pedestrians crossing streets in a traffic system with driving rules that were unfamiliar to them. Pedestrians from mainland China (which has a right-side driving (RD) system) and Hong Kong (which has a left-side driving (LD) system) were studied. Significant differences were observed between pedestrians from the different locations in terms of the direction in which the pedestrians habitually first looked before crossing. When exposed to an unfamiliar driving rule (i.e., traffic coming from an inconsistent direction in terms of participants' habitual driving system), the odds of participants from mainland China making an error in their looking behavior were 2.93 times those when exposed to a familiar driving rule. Road markings and traffic sound did not improve these participants' looking behavior. The results also show a negative correlation between inattentive looking behavior and time to collision (significant at the 1% level), as these errors lead to a shorter time to collision and increased the risk to pedestrians. The results of this study confirmed the risks for pedestrians traveling to places with unfamiliar driving rules and confirmed the existence of habitual looking behavior, and therefore provide evidence of the need for future studies to improve this problem. These may help decision makers take the risks of pedestrians from different driving rules into consideration in future traffic policymaking or traffic-facility improvements. The use of a VR simulation-based approach in this study provided a safe and controllable way to trial interventions and potential improvements without risking injury to participants, and thus may also be used for similar future studies.

Abstract
An eight-channel magnetic probe diagnostic system has been designed and installed adjacent to the 4.6 GHz lower hybrid (LH) grill antenna in the low-field side of the Experimental Advanced Superconducting Tokamak (EAST) in order to study the n∥ evolution of LH waves in the first pass from the launcher to the core plasma. The magnetic probes are separated by 6.6 mm, which allows measurement of the dominant parallel refractive index n∥ up to n∥ = 5 for 4.6 GHz LH waves. The magnetic probes are designed to be sensitive to the magnetic field component perpendicular to the background magnetic field with a slit on the casing that encloses the probe. The intermediate frequency stage, which consists of two mixing stages, down-coverts the frequency of the measured wave signals at 4.6 GHz to 20 MHz. A bench test demonstrates the phase stability of the magnetic probe diagnostic system. By evaluating the phase variation of the measured signals along the background magnetic field, the dominant n∥ of the LH wave in the scrape-off layer has been deduced during the 2019 experimental campaign. In the low density plasma, the measured dominant n∥ of the LH waves is about 2.1, corresponding to the main peak 2.04 of the launched n∥ spectrum. n∥ deduced by the least-squares linear fit method remains near this value in the low density plasma with a high spatial correlation magnitude of 0.9. With an eight-channel probe system, a wave-number spectrum has also been deduced, which has a peak near to the measured dominant n∥.

Abstract
Objective: To survey the children under 7 years of age in nine cities of China for a better understanding of the current situation of childhood stunting. Methods: According to a stratified cluster sampling design, a cross-sectional survey on children under 7 years of age was carried out in 9 cities (Beijing, Harbin and Xi'an in northern China; Shanghai, Nanjing and Wuhan in central China; and Guangzhou, Fuzhou and Kunming in southern China) from June to November in 2016. A total of 110 499 children were recruited. Height of children was evaluated using the growth standards for Chinese children (2009 edition) .Children with height less than the 3rd percentile of the growth standards were considered as stunting, and children with height between the 3rd and 10th percentiles of the growth standards were considered as relatively short stature. Chi-square test was used for comparison between data of boys and girls, urban and suburban, as well as among different ages and regions. Results: Totally 113 084 children under 7 years of age should be investigated and actually 110 499 children were investigated, with a rate of 97.7%. The prevalence of stunting was 1.9% (2 141/110 499) among all the children. The prevalence of stunting in urban children (1.6%, 904/55 524) was lower than that in suburban children (2.3%, 1 237/54 975, χ(2)=56.246, P<0.01). The gender difference in stunting prevalence was not statistically significant (1.9% (1 121/57 921) in boys and 1.9% (1 020/52 578) in girls, χ(2)=0.003, P=0.965). The prevalence of stunting decreased with age for children younger than 3 years, from 1.8% (312/17 080) in 0-<1 year of age group to 1.2% (168/13 740) in 2-<3 years of age group, but increased to 2.2% (240/11 073) at 6-<7 years group. Comparison among different regions showed that the stunting prevalence in southern region was higher than those in the central and northern regions (0.9% (193/20 374) in northern urban, 0.8% (154/18 486) in central urban, and 3.3% (557/16 664) in southern urban children), showing a statistical significance (χ(2)=437.736, P<0.01); 1.1% (241/21 924) in northern suburban, 1.4% (227/16 775) in central suburban and 4.7% (769/16 276) in southern suburban children, showing a statistical significance (χ(2)=646.533, P<0.01). In urban areas, the difference between the central and northern regions showed no statistical significance (χ(2)=1.429, P=0.232) and the stunting prevalence of central Chinese children was slightly higher than that of northern Chinese children in suburban areas (χ(2)=5.130, P=0.024). Among the nine cities, the stunting prevalence of Guangzhou (6.1%, 613/10 019) was higher than those of other cities (χ(2)=1 559.64, P<0.01). Among the stunting children, 78.4% (1 679/2 141) were classified as borderline or mild and only 7.2% (154/2 141) were classified as severe. The prevalence of relatively short stature was 5.2% (5 721/110 499). Conclusions: The prevalence of stunting among children under 7 years of age in nine cities of China is low and most of the stunting children were classified as mild; the prevalence of stunting in suburban children is higher than that in urban children; the gender difference show no statistical significance; and the prevalence of stunting in southern Chinese children is higher than those in central and northern Chinese children.

Abstract
A general south-north genetic divergence has been observed among Han Chinese in previous studies. However, these studies, especially those on mitochondrial DNA (mtDNA), are based either on partial mtDNA sequences or on limited samples. Given that Han Chinese comprise the world's largest population and reside around the whole China, whether the north-south divergence can be observed after all regional populations are considered remains unknown. Moreover, factors involved in shaping the genetic landscape of Han Chinese need further investigation. In this study, we dissected the matrilineal landscape of Han Chinese by studying 4,004 mtDNA haplogroup-defining variants in 21,668 Han samples from virtually all provinces in China. Our results confirmed the genetic divergence between southern and northern Han populations. However, we found a significant genetic divergence among populations from the three main river systems, that is, the Yangtze, the Yellow, and the Zhujiang (Pearl) rivers, which largely attributed to the prevalent distribution of haplogroups D4, B4, and M7 in these river valleys. Further analyses based on 4,986 mitogenomes, including 218 newly generated sequences, indicated that this divergence was already established during the early Holocene and may have resulted from population expansion facilitated by ancient agricultures along these rivers. These results imply that the maternal gene pools of the contemporary Han populations have retained the genetic imprint of early Neolithic farmers from different river basins, or that river valleys represented relative migration barriers that facilitated genetic differentiation, thus highlighting the importance of the three ancient agricultures in shaping the genetic landscape of the Han Chinese.

Abstract
ABSTRACT
The compatibility between solution polymerized styrene–butadiene rubber (SSBR 2466) and natural rubber (NR) is characterized by differential scanning calorimetry and dynamic mechanical thermal analysis. The single glass transition in the entire temperature range of all NR/SSBR blends and good correlation between Tg and SSBR fraction prove the excellent compatibility between SSBR 2466 and NR. With increasing SSBR content, a reduced Payne effect, more homogeneous dispersion of silica, stronger rubber–filler interaction, and more silica selectively distributed in the SSBR phase were determined via rubber-processing analysis, transmission electron microscopy, bound rubber, and thermogravimetric analysis, respectively. The high vinyl content, low styrene content, and end-functionalized structure of SSBR play vital roles in promoting its compatibility with NR and a stronger rubber–silica linkage. The resulting increased tan δ at 0 °C and low tan δ at 60 °C indicates good wet-skid resistance and low rolling resistance by blending SSBR 2466, and 70/30 NR/SSBR is the best balance for producing a “green tire” tread.

Abstract
Objective: To explore the effects of citric acid on patients with severe burn complicated with acute renal injury treated by continuous renal replacement therapy (CRRT). Methods: Medical records of 83 patients with large area of burn complicated with acute renal injury admitted to intensive care unit (ICU) of our department from January 2015 to December 2018 and meeting the inclusion criteria were analyzed retrospectively. The patients were divided into heparin group [n=43, 25 males and 18 females, aged (35.0±2.5) years] and citric acid group [n=40, 22 males and 18 females, aged (37.0±6.6) years] according to different anticoagulation methods. After admission, routine support treatment and CRRT were performed after being diagnosed with acute renal injury in patients in 2 groups. Patients in heparin group were treated with low molecular weight heparin for anticoagulation with first dosage of 20 U/kg and an increase of 2.5 to 5.0 U per hour, and patients in citric acid group were given citric acid of 0.02 g/mL with dosage of 150~200 mL/h for anticoagulation. The use time of blood filter, recovery time of urine volume, and time of staying in ICU, and platelet count, activated partial thromboplastin time (APTT), prothrombin time (PT), and serum creatinine, urea nitrogen, cystatin C, procalcitonin, C-reactive protein, and neutrophil, leukocyte count, blood sugar, aspartate aminotransferase (AST), alanine aminotransferase (ALT), and heart rate, body temperature, and mean arterial pressure before treatment and post treatment hour (PTH) 24 were recorded. Besides, occurrence of hemorrhage, hypocalcemia, metabolic acidosis, metabolic alkalosis, and death within 28 days post injury were recorded. Data were processed with t test and chi-square test. Results: The use time of blood filter of patients in citric acid group was (28.7±3.2)h, significantly longer than (19.4±2.6) h in heparin group (t=14.139, P<0.01). The recovery time of urine volume and time of staying in ICU of patients in citric acid group were respectively (7.6±0.9) and (9.6±1.3) d, significantly shorter than (9.2±1.5) and (11.2±1.8) d in heparin group (t=5.516, 4.697, P<0.01). Before treatment, there were no statistically significant differences in platelet count, APTT, and PT of patients in 2 groups (t=1.235, 0.515, 1.279, P>0.05). At PTH 24, the platelet count of patients in citric acid group was significantly higher than that in heparin group (t=10.947, P<0.01), and APTT and PT of patients in citric acid group were significantly shorter than those in heparin group (t=7.069, 9.142, P<0.01). Before treatment, there were no statistically significant differences in serum creatinine, urea nitrogen, and cystatin C of patients in 2 groups (t=1.684, 1.878, 1.472, P>0.05). At PTH 24, the serum creatinine, urea nitrogen, and cystatin C of patients in citric acid group were significantly lower than those in heparin group (t=7.778, 9.776, 5.117, P<0.01). Before treatment, there were no statistically significant differences in serum procalcitonin and C-reactive protein of patients in 2 groups (t=1.413, 0.898, P>0.05). At PTH 24, the serum procalcitonin and C-reactive protein of patients in citric acid group were significantly lower than those in heparin group (t=2.635, 2.297, P<0.05). Before treatment, there were no statistically significant differences in neutrophil, leukocyte count, blood sugar, AST, and ALT of patients in 2 groups (t=0.555, 0.816, 0.470, 1.896, 0.982, P>0.05). At PTH 24, the neutrophil, leukocyte count, blood sugar, AST, and ALT of patients in citric acid group were significantly lower than those in heparin group (t=2.054, 3.314, 7.185, 2.151, 3.013, P<0.05 or P<0.01). Before treatment, there were no statistically significant differences in heart rate, body temperature, and mean arterial pressure of patients in 2 groups (t=1.406, 0.474, 0.720, P>0.05). At PTH 24, the heart rate, body temperature, and mean arterial pressure of patients in citric acid group were significantly lower than those in heparin group (t=2.307, 4.498, 2.056, P<0.05 or P<0.01). The incidence of hemorrhage of patients in citric acid group while in hospital was significantly lower than that in heparin group (χ(2)=4.949, P<0.05). There were no statistically significant differences in incidence of hypocalcemia, metabolic acidosis, metabolic alkalosis, and death rate within 28 days post injury of patients in 2 groups while in hospital (χ(2)=3.346, 0.884, 0.297, 0.324, P>0.05). Conclusions: Citric acid has significant anticoagulant effect on patients with large area of burn complicated with acute renal injury treated by CRRT, which can prolong the use time of the blood filter, shorten the recovery time of urine volume and time of staying in ICU, improve renal function indexes, blood biochemical indexes, and inflammation indexes, maintain the stability of internal environment, and reduce the risk of hemorrhage.

Abstract
Abstract
Intracerebral hemorrhage (ICH) causes 10%-20% of all strokes and results in higher morbidity compared to other subtypes of cerebral stroke. Although early surgical intervention can clear the expanding hematoma, clinical outcomes following ICH have not significantly improved over the decades. Since ICH elicits neuroinflammation to exacerbate brain edema, damage the blood-brain barrier (BBB), lead to secondary neuronal injury, anti-inflammation may be a critical therapeutic strategy. Mesenchymal stem cell (MSC) therapy processes anti-inflammatory, immunomodulatory and tissue regenerative properties, suggesting that MSC therapy could be an effective therapy for ICH. Therefore, this study tested the hypothesis that human induced pluripotent stem cell-derived mesenchymal stem cell (iPSC-MSC) therapy could effectively reduce brain-infract volume (BIV) and improve neurological function in rat after acute ICH induced by a weight-drop device. Adult-male SD rats (n=40) were equally divided into group 1 (sham-operated control), group 2 (ICH), group 3 (ICH + hyaluronic acid (HA)/intracranial injection/3h after ICH), group 4 [ICH + HA + iPSC-MSC (1.2x106 cells/intracranial injection/3h after ICH)] and euthanized by day 28 after ICH procedure. In vitro study showed that hemorrhagic-brain tissue augmented protein expressions of inflammation (HMGB1/MyD88/TLR-4/TLR-2/NF-κB/TNF-α/iNOS/IL-1β) in cultured neurons that were significantly inhibited by iPSC-MSC treatment (all p<0.001). By days 7/14 after ICH procedure, circulating inflammatory levels of TNF-α/IL-6/MPO expressed were lowest in group 1, highest in group 2 and significantly lower in group 4 than in group 3 (all p<0.0001). By day 14 after ICH procedure, neurological function and BIV expressed an opposite pattern, whereas protein expressions of inflammation (HMGB1/MyD88/TLR-4/TLR-2/NF-κB/I-kB/TNF-α/iNOS/IL-1β/MMP-9), oxidative stress (NOX-1/NOX-2/oxidized protein) and apoptosis (mitochondrial-Bax/cleaved-caspase-2/PARP) in brain exhibited an identical pattern to circulating inflammation among the four groups (all p<0.001). Microscopy demonstrated that the number of vascular remodeling/GFAP+/53BP1+/γ-H2AX+ cells displayed an identical pattern of inflammation, whereas the NeuN+ cells displayed an opposite pattern of inflammation among the four groups (all p<0.001). In conclusion, iPSC-MSC therapy markedly reduced BIV and preserved neurological function mainly by inhibiting inflammatory/oxidative-stress generation.
