Abstract
Objective: To investigate the related factors associated with the structure of the gut microbial community in HIV infection/AIDS cases (HIV/AIDS) in Henan province. Methods: The convenience sampling method was used to select 122 cases who were receiving Antiviral Treatment (ART) or ART-naive in Henan. Whole blood and stool specimens were collected. Genomic DNA of stool samples was extracted, and the V3-V4 hypervariable regions of the 16S rRNA gene were sequenced using Illumina NovaSeq 6000 high-throughput sequencing system. The analysis was performed mainly at the genus level, and the 30 genera with the highest abundance were selected as a measure of the gut microbial community structure. The correlation between community structure and related factors was analyzed using redundancy analysis and Envfit function. Results: 122 cases were finally completed sequencing and analysis, the average BMI was (23.62±2.78) kg/m2 and the average age was (47±13) years. Among them, male accounted for 66.39% (81/122), and heterosexual transmission route constituted the largest ratio, accounting for 51.64% (63/122). 36 cases were treatment naive (29.51%, 36/122). The top five dominant genera of the total population (122 cases) were Prevotella, Roseburia, Megamonas, Bacteroides and Faecalibacterium and the top five dominant genera of the ART population (86 cases) were Prevotella, Megamonas, Bacteroides, Roseburia and Faecalibacterium. The top five dominant genera of the ART-naive population (36 cases) appeared as Prevotella, Faecalibacterium, Roseburia, Bacteroides and Megamonas. In the total population, ART (P<0.001) was the most significant factors of community structure. Other significant factors were: duration of diagnosis (P=0.009), viral load (P=0.022) and anti-HCV (P=0.018). ART was positively correlated with Megamonas and negatively correlated with Prevotella, Roseburia and Faecalibacterium, while the other three factors of duration of diagnosis, viral load and anti-HCV were positively correlated with Prevotella, Roseburia and Faecalibacterium and negatively correlated with Megamonas. In the ART-naive population, duration of diagnosis (P=0.003) were the factors significantly associated with community structure. Duration of diagnosis was positively correlated with Roseburia, Faecalibacterium, Megamonas and Prevotella and negatively correlated with Bacteroides. Conclusion: ART and duration of diagnosis were factors significantly associated with gut microbial community structure and had a significant impact on multiple high-abundance genera.

Abstract
OBJECTIVE Poststroke dysphagia (PSD) is one of the most significant problems after stroke. The prognosis of dysphagia is closely related to the outcomes of stroke. This meta-analysis aimed at identifying and evaluating critical predictors of prognosis for PSD. MATERIALS AND METHODS Electronic databases were searched for relevant case-control and cohort studies in which the prognostic factors of PSD were reported. The methodological quality of the studies was assessed using the Newcastle-Ottawa Scale. Review Manager 5.3 was used to calculate odds ratios (OR) and their 95% confidence intervals (CI) of the included factors and to perform heterogeneity and sensitivity analyses. Stata 15.1 was used to evaluate publication bias. RESULTS Eighteen of 3132 total studies were finally included in this meta-analysis. Ten predictors of PSD were identified, including 2 protective factors and 8 risk factors. Early intervention (OR=0.75, 95% CI=0.61-0.93) and an MRS (modified Rankin scale) score of 0 before onset (OR=0.58, 95% CI=0.47-0.71) were related to a better prognosis of PSD. The risk factors ranked by pooled OR values were aspiration (OR=7.64, 95% CI=5.94-9.82), brainstem injury (OR=4.82, 95% CI=3.01-7.72), severity of stroke (OR= 3.06, 95% CI=1.69-5.53), bihemispheric injury (OR=3.0, 95% CI=1.67-5.40), older age (OR=1.75, 95% CI=1.50-2.04), malnutrition (OR=1.36, 95% CI=1.22-1.53), severe dysphagia on admission (OR=1.16, 95% CI=1.03-1.29), and reduced level of consciousness (OR=1.03, 95% CI=1.00-1.07). CONCLUSIONS Prognostic factors for a good outcome of PSD included early intervention and an MRS score of 0 before onset. Aspiration, brainstem injury, severe stroke and bihemispheric injury are the four most significant predictors of poor prognosis in PSD. Identifying these prognostic factors should help clinicians to better detect patients at risk and provide effective interventions for PSD.

Abstract
Abstract Abstract: Objective To analyze the first epidemic spread of the novel coronavirus Delta variant in China based on public security forensic perspective, investigate its transmission characteristics, contributing factors, and epidemiologic research experience, and provide a reference for the prevention and control of the epidemic caused by the novel coronavirus variant. Methods Based on the information that public security forensic experts obtained from front-line epidemiologic research, the gender, age, place of residence, transmission route and infectivity of the coronavirus disease 2019 (COVID-19) confirmed cases, asymptomatic infected persons and their close contacts in Guangzhou caused by the novel coronavirus Delta variant were analyzed. The basic reproduction number (R0) during this epidemic in Guangzhou was calculated. Results Among the 153 cases infected with novel coronavirus Delta variant in the epidemic, 63 cases were male and 90 cases were female, their age ranging from 1 to 92 years, with a median age of 49 years. The main route of transmission was close contact, including dining together, co-living, and close contact in the same residential building. There were 31 cases of family clusters, 25 of which were in Liwan District. The epidemic lasted from May 26 to May 29, and the R0 remained above 4.0. After May 30, R0 began to decline and remained below 1.0 from June 7. Conclusion The novel coronavirus Delta variant is highly infectious, the crowd is generally susceptible to infection and family cluster cases are easy to occur. So, it is necessary to precisely prevent and control this strain. Public security forensic experts have both medical literacy and criminal investigation capabilities, they can play a more professional role in epidemic prevention and control.

Abstract
The cognitive representation of oneself is central to other sociocognitive processes, including relations with others. It is reflected in faster, more accurate processing of self-relevant information, a “self-prioritisation effect” (SPE) which is inconsistent across studies in autism. Across two tasks with autistic and non-autistic participants, we explored the SPE and its relationship to autistic traits, mentalizing ability and loneliness. A SPE was intact in both groups, but together the two tasks suggested a reduced tendency of late-diagnosed autistic participants to differentiate between familiar and unfamiliar others and greater ease disengaging from the self-concept. Correlations too revealed a complex picture, which we attempt to explore and disentangle with reference to the inconsistency across self-processing studies in autism, highlighting implications for future research.

Abstract
Objective: To analyze the characteristics of clinical distribution and change of aeroallergens in children with allergic diseases from 2015 to 2020. Methods: Children who visited Capital Institute of Pediatrics affiliated Children's Hospital, suspected of allergic diseases and received serum aeroallergens specific immunoglobulin E (sIgE) test were retrospectively enrolled (1 to 14 years old). sIgE was detected by Phadia1000 system with radioallergosorbent test fluorescent enzyme-linked immunoassay. The characteristics and change of the aeroallergens among the 6 years was analyzed. Enumeration data were expressed by percentage and categorical variables were compared by the independent samples t-test and Pearson χ2 test. Results: In total 4 608 tests (4 575 patients) of children were enrolled, the average age was (5.4±2.9) years old, with the median age of 5.0 years old. 3 176 were boys (68.9%), and 1 432 were girls (31.1%). 4 294 children were from the north of China (93.2%), 295 children were from the south of China (6.4%), and 19 children were from unknown regions (0.4%). In total the most common aeroallergen was mold mixture (1 956/4 457 tests, 43.9%) and Alternaria alternata (276/630 tests, 43.8%), followed by Artemisia (300/889 tests, 33.7%), Humulus scandens (12/38 tests, 31.6%) and grass mixture (909/2 874 tests, 31.6%). Among the 6 years, mold, grass pollen and tree pollen sensitization increased, and mold [38/130 (29.2%) vs 1 574/3 233 (48.7%)], grass pollen [11/77 (14.3%) vs 1 069/3 072 (34.8%)] increased significantly (χ2 was 18.953 and 49.559, respectively, P=0.000). Positive rate of tree pollen increased [1/10 (10.0%) vs 516/2 122 (24.3%)], but did not have statistical significance (χ²=1.111, P=0.292). Dust mite [36/146 (24.7%) vs 321/1 408 (22.8%)] and hair of pets [7/33 (21.2%) vs 321/1 408 (17.1%)] sensitization didn't change greatly (χ2 =0.258, P =0.611; χ2 =0.379, P =0.538). In 2015, the most common aeroallergens was mold (38/130, 29.2%), followed by dust mite (36/146, 24.7%), while in 2020, the most common aeroallergens was still mold (1 574/3 233, 48.7%), with grass pollen (1 069/3 072, 34.8%) and tree pollen (516/2 122, 24.3%) ranked after. Conclusion: Mold might be the most common aeroallergens in allergic children in Beijing area. With time went on, dust mite was gradually exceeded by grass pollen and tree pollen.

Abstract
Objective: To investigate the effect of long non-coding RNA HOTAIR (LncRNA HOTAIR) on the proliferation, apoptosis and drug resistance of Wilms tumor cells and its molecular mechanism. Methods: Collected nephroblastoma tissues and normal tumor side tissues in 32 children with renal syblastoma surgical treatment at Zhengzhou University Children's Hospital from 2015 to 2019. Real-time quantitative reverse transcription polymerase chain reaction, (qRT-PCR)was used to detect the expression of HOTAIR in Wilms tumor tissues and adjacent tissues. Small interfering RNA technology was used to delete the expression of HOTAIR in Wilms tumor cell SK-NEP-1. Cell counting kit-8 (CCK-8)was used to detect cell proliferation after transfection. Flow cytometry and terminal deoxynucleotidyl transferase mediated dUTP nick-end labeling (TUNEL) staining to detect the apoptosis. Western blot was used to detect the expression of Wnt/β-catenin signaling pathway related proteins.CCK-8 was used to detect the proliferation inhibition of cells treated with different concentrations of cisplatin after transfection. Results: Compared with adjacent tissues, HOTAIR was highly expressed in Wilms tumor tissues (P<0.05). The expression levels of Wnt, β-catenin, Cyclin D1, c-myc in the control group were (0.89±0.08), (0.94±0.10), (0.72±0.06), (1.10±0.11), and (1.06±0.11), (0.92±0.08), (0.66±0.07), (1.25±0.11) of the si-RNA group, while (0.54±0.05), (0.41±0.05), (0.25±0.03), (0.56±0.06) of the si-HOTAIR group. The expression levels of these protein were significantly down-regulated in the si-HOTAIR group when compared with the control group and the si-RNA group (P<0.05). The absorbance (A) values of SK-NEP-1 cells in the si-HOTAIR group at 24, 48 and 72 hours after transfection were (0.31±0.02), (0.37±0.04), (0.69±0.07), significantly lower than (0.49±0.05), (0.78±0.08), (1.22±0.14) in the control group and (0.57±0.06), (0.68±0.07), (0.94±0.09) in the si-RNA group (P<0.05). The apoptosis rate in the si-HOTAIR group was (13.81±1.25)%, significantly higher than (6.54±0.72)% in the control group and (4.35±0.40)% in the si-RNA group (P<0.05). The cell positive rate of TUNEL cells in the si-HOTAIR group was (35.14±3.50)%, significantly higher than (20.16±2.18)% in the control group and (21.09±2.35)% in the si-RNA group (P<0.05). The median inhibitory concentration (IC(50)) of the si-HOTAIR group was (62.48±5.97) μmol/L, significantly lower than (88.27±9.05) μmol/L of the control group and (92.50±9.11) μmol/L of the si-RNA group (P<0.05). Conclusions: Suppression of LncRNA HOTAIR can inhibit the proliferation of Wilms tumor cells, promote cell apoptosis, decrease cell resistance to cisplatin. The mechanism may be related to the inhibition of Wnt/β-catenin signaling pathway activation.

Abstract
The central challenge in building a quantum computer is error correction. Unlike classical bits, which are susceptible to only one type of error, quantum bits (qubits) are susceptible to two types of error, corresponding to flips of the qubit state about the X and Z directions. Although the Heisenberg uncertainty principle precludes simultaneous monitoring of X- and Z-flips on a single qubit, it is possible to encode quantum information in large arrays of entangled qubits that enable accurate monitoring of all errors in the system, provided that the error rate is low1. Another crucial requirement is that errors cannot be correlated. Here we characterize a superconducting multiqubit circuit and find that charge noise in the chip is highly correlated on a length scale over 600 micrometres; moreover, discrete charge jumps are accompanied by a strong transient reduction of qubit energy relaxation time across the millimetre-scale chip. The resulting correlated errors are explained in terms of the charging event and phonon-mediated quasiparticle generation associated with absorption of γ-rays and cosmic-ray muons in the qubit substrate. Robust quantum error correction will require the development of mitigation strategies to protect multiqubit arrays from correlated errors due to particle impacts.

Abstract
Stray laser light is a serious problem that interrupts the measurement of electron temperature and density in Thomson scattering (TS) systems. This paper presents a ray-tracing simulation of stray laser light in HL-2M TS systems. A model including (i) a simplified laser-beam injection system, (ii) the scattered-light collection systems for central-point TS (CPTS) and edge TS (ETS), and (iii) the HL-2M vessel is built using the TracePro and CATIA software packages based on measurements of the bidirectional scattering distribution function at a wavelength of 532 nm. The simulation results show that no stray laser light reaches the injection surface of the collection lens of the CPTS system, and only a few stray laser rays of all the rays reaching the injection surface of the collection lens of the ETS system can be collected when the energy threshold per ray is 1 × 10-16. The stray laser rays that reach the scattered-light collection systems are mainly from the first and second parts of the slides of the beam dump, so decreasing the roughness of those parts could be effective in reducing the level of stray laser light.

Abstract
OBJECTIVE More than 300 genetic variants have been robustly associated with measures of human adiposity. Highly penetrant mutations causing human obesity do so largely by disrupting satiety pathways in the brain and increasing food intake. Most of the common obesity-predisposing variants are in, or near, genes expressed highly in the brain, but little is known of their function. Exploring the biology of these genes at scale in mammalian systems is challenging. We sought to establish and validate the use of a multicomponent screen for feeding behaviour phenotypes, taking advantage of the tractable model organism Drosophila melanogaster. METHODS We validated a screen for feeding behaviour in Drosophila by comparing results after disrupting the expression of centrally expressed genes that influence energy balance in flies to those of 10 control genes. We then used this screen to explore the effects of disrupted expression of genes either a) implicated in energy homeostasis through human genome-wide association studies (GWAS) or b) expressed and nutritionally responsive in specific populations of hypothalamic neurons with a known role in feeding/fasting. RESULTS Using data from the validation study to classify responses, we studied 53 Drosophila orthologues of genes implicated by human GWAS in body mass index and found that 15 significantly influenced feeding behaviour or energy homeostasis in the Drosophila screen. We then studied 50 Drosophila homologues of 47 murine genes reciprocally nutritionally regulated in POMC and agouti-related peptide neurons. Seven of these 50 genes were found by our screen to influence feeding behaviour in flies. CONCLUSION We demonstrated the utility of Drosophila as a tractable model organism in a high-throughput genetic screen for food intake phenotypes. This simple, cost-efficient strategy is ideal for high-throughput interrogation of genes implicated in feeding behaviour and obesity in mammals and will facilitate the process of reaching a functional understanding of obesity pathogenesis.

Abstract
Objective: To observe the alteration of clinical features of intrahepatic lymphocyte subsets in C57BL/6N-TG (1.28HBV)/Vst hepatitis B virus (HBV) transgenic mice composite carbon tetrachloride (CCl(4)) with intraperitoneal injection under the background of hepatitis B to induce liver fibrosis mice model, and analyze their correlation with serum HBV DNA and liver tissue hydroxyproline (Hyp) content. Methods: HBV-Tg mice were intraperitoneally injected with 10% CCl(4) to induce the rapid formation of hepatic fibrosis. Serum HBV DNA, HBsAg, HBeAg levels and liver tissue HBsAg expressional conditions were used to evaluate the virological characteristics of mice model. The degree of hepatic inflammation and fibrosis in mice were observed by HE, Sirius Red staining and liver tissue hydroxyproline (Hyp) content. Intrahepatic T lymphocyte, B lymphocyte, CD4+T lymphocyte, CD8+T lymphocyte, natural killer (NK) cell and natural killer T (NKT) cells distribution were observed by flow cytometry. One-way analysis of variance was used for intergroup data comparison, and LSD was used for pairwise comparison. Pearson's correlation analysis was used to analyze the correlation between the above lymphocyte subsets and serum HBV DNA and liver tissue Hyp content. Results: Serum HBsAg, HBeAg and liver tissue HBsAg had equal positive expression in the HBV-Tg composite CCl(4) mice model group, and the serum HBV DNA load was > 1 × 10(6) IU / ml. Compared with the wild-type control group, liver tissue Hyp content of the composite model group was significantly higher [(196.39 ± 38.14) μg /g and (347.67 ± 59.53) μ g/g, P < 0.01). The degree of inflammation and fibrosis in liver tissues was aggravated, and the proportion of all intrahepatic CD4+T, NK and NKT cells was significantly reduced (P < 0.01), while the proportion of CD8+T lymphocytes (30.58% ± 2.89% vs. 46.50% ± 2.24%, P < 0.01) and B lymphocytes (28.82% ± 2.24% vs. 37.10% ± 8.59%, P < 0.05) was significantly increased. Serum HBV DNA level was positively correlated with the proportion of intrahepatic T lymphocytes (r = 0.413, P < 0.05), and negatively correlated with the proportion of NK cells (r = -0.419, P < 0.05). Liver tissue Hyp content was negatively correlated with the proportion of all CD4+T lymphocytes (r = -0.871), NK cells (r = -0.716), and NKT cells (r = -0.876) (all P < 0.01), and positively correlated with the proportion of all CD8 + T lymphocytes (r = 0.852), and B lymphocytes (r = 0.593) (all P < 0.01). Conclusion: HBV-Tg composite CCl4 mice model can induce positive HBV virological indicators, liver inflammation and fibrosis in mice model of hepatitis B coexisting with fibrosis. This model has the features of immune disorder of liver lymphocyte similar to human disease, and the immune disorder of intrahepatic lymphocytes is correlated with HBV viral load and liver fibrosis degree.

Abstract
We report distress levels and functional outcomes based on self-reported pre-existing mental health conditions among U.S. young adults (N=898) during the COVID-19 pandemic (April 13-May 19, 2020). Depression, anxiety, and PTSD symptoms, as well as COVID-19-related concerns, sleep problems, and quality of life were compared across the following pre-existing mental health groups: 1) no diagnosis, 2) suspected diagnosis, 3) diagnosed and untreated, and 4) diagnosed and treated. Compared to those without a diagnosis, the likelihood of scoring above the clinical threshold for those with a diagnosis - whether treated or not - was more than six-fold for depression, and four-to six-fold for anxiety and PTSD. Individuals with a suspected diagnosis were 3 times more likely to score above the clinical threshold for depression and anxiety and 2 times more as likely to score above this threshold for PTSD compared to those with no diagnosis. We also present higher levels of COVID-19-related worry and grief, poorer sleep, and poorer reported health-related quality of life among those with either a suspected or reported mental health diagnosis. Findings provide evidence of vulnerability among individuals with a mental health diagnosis or suspected mental health concerns during the initial weeks of the COVID-19 pandemic.

Abstract
Objective To investigate the population genetic data of 47 autosomal insertion/deletion (InDel) polymorphism genetic markers involved in AGCU InDel 50 kit in Guangdong Han, Guangxi Zhuang, Guangxi Yao, Guangxi Jing, and Guangxi Mulam, and to evaluate their application in forensic DNA identification. Methods Multiplex amplification of the 768 unrelated individuals from the 5 ethnic groups mentioned above was performed with the AGCU InDel 50 kit. Genotyping was carried out by 3500xL gene analyzer, population genetic parameters were gathered and polymorphism analysis was performed. Results No linkage disequilibrium was found among 47 autosomal InDel loci in the 5 ethnic groups. The distribution of genotype frequency of 47 autosomal InDel loci confirmed to the Hardy-Weinberg equilibrium in Guangdong Han and Guangxi Zhuang. Except for rs139934789, the other 46 loci confirmed to the Hardy-Weinberg equilibrium in Guangxi Yao, Guangxi Jing, and Guangxi Mulam. The results of genetic variation analysis among the populations showed that 1.12% of genetic variation was caused by ethnic group differences. The cumulative discrimination power of 47 autosomal InDel loci for the 5 ethnic groups were all above 0.999 999 999 999 999. The cumulative probability of exclusion for each ethnic group was less than 0.999 9. The two Y-InDels were identified in all male individuals and were absent in all female individuals. Conclusion Except for rs139934789, the other 46 InDel loci have a relatively good genetic polymorphism in the 5 Chinese ethnic groups, and can be used for forensic individual identification and as effective supplements for paternity testing.

Abstract
Objective: To explore the cutoff value of FEV(1)/FVC for evaluating obstructive ventilation dysfunction in children. Methods: Three hundred and eighty-three healthy children (190 boys and 193 girls) aged 6-14 years in primary and middle school in Beijing, who were enrolled from May 2010 to June 2011, had their spirometry done with the Jaeger lung function instrument, and the lower limit of normal (LLN) of FEV(1)/FVC was calculated. Two hundred and thirteen asthmatic children (151 boys and 62 girls) aged 6-14 years from the outpatient Department of Allergy, Capital Institute of Pediatrics were enrolled consecutively from June to July 2018, whose clinical history and pulmonary function parameters were collected. The expected value of spirometric parameters of asthmatic children was calculated according to Zapletal prediction equations. And the LLN of FEV(1)/FVC in healthy children was used as the gold standard to calculate the sensitivity, specificity, Youden index and Kappa value of FEV(1)/FVC<80% and FEV(1)/FVC< 92% predicted. Results: In healthy children, the FEV(1)/FVC and the LLN were 91%±5% and 82% respectively, while 90%±6% and 81% in boys, and 92%±5% and 84% in girls. There were 27 (12.7%) asthmatic children whose FEV(1)/FVC<80% but FEV(1)/FVC≥92% predicted (χ(2)=123.7, P<0.01). The sensitivity, specificity, Youden index and Kappa value of FEV(1)/FVC<80% were 80.3%, 100%, 0.803 and 0.787 respectively when FEV(1)/FVC<80% was used as the criteria to assess lung function, while they were 57.3%, 100%, 0.573 and 0.547, respectively, when FEV(1)/FVC<92% predicted was used as criteria. Conclusions: The 80% of FEV(1)/FVC has a better consistency with the LLN of FEV(1)/FVC than 92% of FEV(1)/FVC% predicted. It is more accarate to use FEV(1)/FVC<80% as the diagnostic criteria for airway obstruction.

Abstract
Objective: To observe the therapeutic effect of terlipressin on refractory ascites (RA) in cirrhosis, and its role and impact on acute kidney injury (AKI). Methods: A non-randomized controlled clinical trial data of 111 hospitalized cases of liver cirrhosis accompanied with RA was collected from Shuguang Hospital Affiliated to Shanghai University of Traditional Chinese Medicine, Zhongshan Hospital of Hubei Province, The First Affiliated Hospital of Zhengzhou University, The First Affiliated Hospital of Medical School of Zhejiang University, and People's Hospital of Pudong New Area of Shanghai between March 2015 and March 2017. 26 cases of conventional treatment group (control group) were divided into two subgroups: RA without AKI (RA-NAKI) and RA with AKI (RA-AKI), and each subgroup consisted 13 cases. Patients with bacterial infection were treated with diuretics, albumin supplementation and antibiotics. 85 cases were presented in terlipressin combined treatment group, of which 27 cases were of RA-NAKI and 58 cases were of RA-AKI. Control group was injected terlipressin 1mg of intravenous drip or static push (once q6 h ~ 12 h) for more than 5 days. The treatment duration lasted for 2 weeks with 4 weeks of follow-up. Body weight, 24-hour urine volume, abdominal circumference, mean arterial pressure (MAP), liver and kidney function, anterior hepatic ascites, deepest point of ascites, and ultrasonographic detection of ascites in supine position before treatment, one and two weeks after treatment and 4 weeks after follow-up were compared. Count data were tested by χ (2). Samples of four groups at baseline were compared. One-way analysis of variance was used for normal distribution data and Kruskal-Wallis H test for non-normal distribution data. Repeated measures analysis of variance was used to compare the difference in efficacy between different time points before and after treatment in the group. The LSD method of one-way ANOVA was used to compare the two groups. A t-test of independent samples was used to compare the efficacy of different time series between the two groups. Mann-Whitney rank- sum test was used to compare the data of non-normal distribution between the two groups. Results: (1) Baseline data were compared among 4 subgroups of terlipressin RA-NAKI and control RA-AKI. Control group age was higher than that of terlipressin group, and the serum creatinine (SCr) of the RA-AKI group was higher than RA-NAKI group, and there was no significant difference in the rest of the baseline data and the combined medication (P > 0.05). (2) An intra-group comparison between control and trelipressin before and after treatment showed that all patients had lower body mass, abdominal circumference and deepest ascites, and higher serum albumin (P < 0.05). 24-hour urine volume and MAP was significantly increased in the terlipressin group, while the pre-ascites, SCr and child Turcotte Pugh (CTP) scores were decreased. Body weight, abdominal circumference, pre-ascites, and deepest ascites of the terlipressin group were decreased, while MAP was increased during the treatment and follow-up periods. The differences were statistically significant when compared with the control group at the same time (P < 0.05). There was a statistically significant difference in the increase of 24-h urine volume in the terlipressin group compared with the control group (P < 0.05). The decrease in SCr and CTP in the terlipressin group after 2 weeks of treatment and 4 weeks of follow-up was statistically significant compared with the control group (P < 0.05). (3) Among the two subgroups of RA-AKI and RA-NAKI in the terlipressin group, the baseline SCr value of the former was higher than that of the latter. After treatment, the body weight, abdominal circumference, pre-ascites, deepest ascites and CTP scores were decreased. In the RA-AKI group, 24-hour urine volume, MAP, SCr and serum albumin concentration were significantly increased. The difference between the two subgroups before and after treatment was compared, and the body weight of RA-AKI group at 1, 2 weeks of treatment and 4 weeks of follow-up was significantly lower than RA-NAKI group, which were (- 2.3 ± 0.2 vs. - 1.5 ± 0.2) kg, (- 4.1 ± 0.2 vs. - 2.6 ± 0.2) kg, (- 4.2 ± 0.3 vs. - 2.4 ± 0.3) kg, respectively. RA-NAKI group urine volume was significantly increased at 2 weeks of treatment and 4 weeks of follow-up, which was (468 ± 42 vs. 110 ± 131) ml, (272 ± 34 ml vs. 11 ± 112) ml, respectively. SCr reduction (18.3 ± 4.7 vs. 0.9 ± 2.4) µmol/l at 4 weeks of follow-up was apparent in RA-NAKI group, and the difference was statistically significant (P < 0.05). Conclusion: Addition of terlipressin to conventional treatment may significantly increase MAP, 24-h urine volume, improve renal function and promote ascites resolution in patients with refractory cirrhotic ascites. Moreover, its combination effect is more obvious in AKI patients, and adverse reactions are mild.

Abstract
In this paper, the effect of channel annealing and oxygen flow rate in P-type tin-monoxide (SnO) thin film transistor (TFT) was investigated to reach the process compatibility with n-type oxide-based TFT. The optimized P-type SnO TFT with a small threshold voltage of -0.1 V, a high field-effect mobility of 4 cm² V-1 s-1 and an on/off current ratio of >10² was proposed. From the experimental results, the 150 °C channel annealing revealed a metallic behavior but a semiconductor-like property at a higher 200 °C that was favorable for transistor rectification. Besides, the higher oxygen flow rate was also helpful for improving device mobility and driving current, but shows a slight increase in off-state leakage, which is unavoidable due to the increase of grain in SnO channel.

Abstract
The membrane-spanning domain (MSD) of the transmembrane subunit (TM) anchors the envelope glycoprotein (Env) on the lipid bilayer of the host cell membrane and virions. Its functions include membrane fusion efficiency and intracellular trafficking of the lentivirus envelope protein. Our study aimed to determine the MSD of bovine immunodeficiency virus (BIV) glycoprotein 45 (gp45) and reveal structural characteristics of the BIV Env protein. We have predicted the region of the BIV MSD and obtained the sequence using bioinformatics software. Various kinds of assays, including analogy analysis, fluorescence microscopy, and dye-transfer-based assays, were carried out to validate the prediction. The results, for the first time, show that the BIV MSD is located at the D170 to M191 amino acids of gp45, and the identified MSD divides gp45 into the extracellular domain (ED), MSD and cytoplasmic domain (CT). We further found that the BIV MSD had a similar structure and function as the HIV MSD using amino acid sequence alignment and fluorescence microscopy. Additionally, the dye-transfer-based assay demonstrates that deletion of the BIV MSD efficiently decreases cell-cell fusion. Based on the identification of the MSD, a "snorkeling" model, in which the flanking charged amino acid residues are buried in the lipid bilayer while their side chains interact with polar head groups, was proposed for the BIV MSD. Ultimately, we further improved the primary structure of the BIV envelope glycoprotein.

Abstract
Objective: To understand the disease progression and human leukocyte antigen (HLA) gene polymorphism of HIV-infected persons without disease progress for long term, also known as long-term non-progressors (LTNPs), in Henan province. Methods: A retrospective study was conducted in 48 LTNPs with complete detection and follow-up information during 2011-2016 in Henan. Changes of CD(4)(+)T cells counts (CD(4)) and viral load (VL) during follow-up period were discussed. Polymerase chain reaction-sequence-specific oligonucleotide probe (PCR-SSOP) was used for the analyses of HLA-A, HLA-B and HLA-DRB1 alleles between LTNPs and healthy controls. Results: From 2011 to 2016, forty-eight LTNPs showed a decrease of the quartile (P(25)-P(75)) of CD(4) from 601.00 (488.50-708.72)/μl to 494.00 (367.00-672.00)/μl, and the difference was significant (P<0.05). The increase of the quartile (P(25)-P(75)) of log(10)VL from 3.40 (2.87-3.97) to 3.48 (2.60-4.37), but the difference was not significant (P>0.05). HLA polymorphism analysis revealed that HLA-B*13:02 and HLA-B*40:06 were more common in LTNPs (P<0.05), while HLA-B*46:01 and HLA-DRB1*09:01 were more common in healthy controls (P<0.05). Conclusions: The CD(4) of LTNPs in Henan showed a downward trend year by year. HLA-B*13:02 and B*40:06 might be associated with delayed disease progression for HIV infected persons in Henan.

Abstract
Objective:To investigate the diagnostic efficiency of HCY and NO/ET-1 to cognitive dysfunction in patients with severe obstructive sleep apnea hypopnea syndrome, and to interfere with the cognitive function of severe OSAHS patients. Method: Eighty-six patients with OSAHS were divided into mild group (22 cases), moderate group (23 cases), severe group (41 cases) and healthy physical examination group (50 cases). The levels of serum HCY and NO/ET-1 were compared between the four groups. The Montreal cognitive assessment scale was used to evaluate the incidence of mild cognitive impairment in severe OSAHS group, and the correlation between the level of serum HCY, NO/ET-1 and cognitive function in severe OSAHS group was analyzed. Result:The level of serum HCY in patients with severe OSAHS with cognitive impairment was(32.28±3.92)μmol/L, higher than that of the cognitive moderate group(26.34±4.05)μmol/L, and mild group (18.62±3.29)μmol/L. The level of serum NO/ET-1 in patients with severe OSAHS with cognitive impairment was (0.69±0.19), higher than that of the cognitive moderate group(2.76±0.28), and mild group (3.98±0.37), the difference was statistically significant (P<0.05). In severe group, there was a negative correlation between the level of serum HCY and the score of MoCA and its subscores (P<0.05), and there was a positive correlation between the total scores of NO/ET-1 and MoCA and their subscores (P<0.05), and negative correlation between HCY and NO/ET-1 (P<0.05). The area under the ROC curve of predicting serum HCY and NO/ET-1 levels in severe OSAHS patients with cognitive impairment were 0.788(95%CI0.654-0.921) and 0.770 (95%CI0.642-0.899). Conclusion:Serum HCY and NO/ET-1 were the factors influencing the formation of cognitive impairment in severe OSAHS patients. The level of HCY was negatively correlated with the degree of cognitive impairment, and NO/ET-1 was positively correlated with the degree of cognitive impairment.

Abstract
In 2009, a new citrus viral disease caused by Citrus yellow vein clearing virus (CYVCV) was first discovered in China and now CYVCV is widely distributed in the field. CYVCV is transmissible by grafting and is spread by aphids from lemon to bean, and from bean to bean. However, until now, no vector has been shown to transmit CYVCV from citrus to citrus. In this study, after a 24-h acquisition access period (AAP), CYVCV was tested for in Dialeurodes citri (Ashmead), Panonychus citri McGregor, and Aphis citricidus (Kirkaldy) by quantitative RT-PCR. After an AAP of 48 h, groups of adults of D. citri, P. citri, and A. citricidus were given a 48 h inoculation access period on cultivar Daidai sour orange seedlings. Three, 6, and 12 months post-transmission by D. citri, CYVCV was detected in the receptor plants, and the mean incidence of infected trees was 31.9, 39.1, and 39.1%, respectively. CYVCV was not transmitted to citrus by P. citri or A. citricidus. This is the first report of the ability of D. citri to transmit CYVCV from infected to healthy citrus under laboratory conditions.

Abstract
OBJECTIVE To investigate the clinical characteristics, the medicine application and to evaluate the disease activity in patients with osteoarthritis (OA) in China. METHODS This was a cross-sectional study. Totally 1 066 cases of OA from 40 hospitals in China from April to October 2017 were retrospectively enrolled. Demographic characteristics, clinical data, medicine application, and joint function were evaluated. All the data were analyzed by SPSS software 19.0. t test, Mann-Whitney U test and chi-square test were used for statistical analysis. RESULTS In the 1 066 cases, the male-to-female ratio was 1:3.6 and the average age was (61.9±11.0) years, with an age range from 36 to 94 years. The incidence of knee OA, hip OA, and hand OA were respectively 81.9% (873/1 066), 14.1% (150/1 066), and 36.3% (387/1 066). In the study, 242 (22.7%) cases had two kinds of joint areas involved and three joint areas were involved in 51 cases (4.8%), and 56.6% (603/1 066) of the patients used more than one kind of non-steroid anti-inflammatory drugs (NSAIDs) while 61.2% (652/1 066) used disease modifying osteoarthritis drugs (DMOADs), including glucosamine (37.5%, 400/1 066), chondroitin sulfate (2.0%, 21/1 066), diacetate (5.9%, 63/1 066), and the combination of these drugs (15.8%, 168/1 066). 8.6% (92/1 066) patients only took analgesics to relieve the pain, not using any kind of NSAIDs or DMOADs. And 232 patients (21.7%) had intra-articular injections, including 9.2% (98/1 066) sodium hyaluronate, 4.5%(48/1 066) glucocorticoid, and 8.1% (86/1 066) combination of the two drugs. The proportion of the patients taking topical drugs accounted for 26.5% (283/1 066) and physical therapy accounted for 15.8% (168/1 066). Compared with those who suffered from knee OA, the patients who suffered from hip OA had more severe disease assessment. Moreover, there were significant differences in pain (Z=-7.625, P<0.001), morning stiffness (Z=-6.229, P<0.001), and joint function (Z=-6.777, P<0.001) between the two groups of the patients who suffered from knee or hip OA with The Western Ontario and McMaster Universities (WOMAC) osteoarthritis index. Furthermore, patients with hip OA took more analgesics (χ2=24.838, P<0.001). CONCLUSION Oral NSAIDs and DMOADs are wildly used in patients with OA in China. However, the treatment of some patients still need to be improved. Patients with hip OA are more seriously ill and require aggressive treatment.
