Abstract
Background & Aims Immunotherapy is an option for the treatment of advanced biliary tract cancer (BTC), although it has a low response rate. In this post hoc analysis, we investigated the predictive value of an immuno-genomic-radiomics (IGR) analysis for patients with BTC treated with camrelizumab plus gemcitabine and oxaliplatin (GEMOX) therapy. Methods Thirty-two patients with BTC treated with camrelizumab plus GEMOX were prospectively enrolled. The relationship between high-throughput computed tomography (CT) radiomics features with immuno-genomic expression was tested and scaled with a full correlation matrix analysis. Odds ratio (OR) of IGR expression for objective response to camrelizumab plus GEMOX was tested with logistic regression analysis. Association of IGR expression with progression-free survival (PFS) and overall survival (OS) was analysed with a Cox proportional hazard regression. Results CT radiomics correlated with CD8+ T cells (r = -0.72-0.71, p = 0.004-0.047), tumour mutation burden (TMB) (r = 0.59, p = 0.039), and ARID1A mutation (r = -0.58-0.57, p = 0.020-0.034). There was no significant correlation between radiomics and programmed cell death protein ligand 1 expression (p >0.96). Among all IGR biomarkers, only four radiomics features were independent predictors of objective response (OR = 0.09-3.81; p = 0.011-0.044). Combining independent radiomics features into an objective response prediction model achieved an area under the curve of 0.869. In a Cox analysis, radiomics signature [hazard ratio (HR) = 6.90, p <0.001], ARID1A (HR = 3.31, p = 0.013), and blood TMB (HR = 1.13, p = 0.023) were independent predictors of PFS. Radiomics signature (HR = 6.58, p <0.001) and CD8+ T cells (HR = 0.22, p = 0.004) were independent predictors of OS. Prognostic models integrating these features achieved concordance indexes of 0.677 and 0.681 for PFS and OS, respectively. Conclusions Radiomics could act as a non-invasive immuno-genomic surrogate of BTC, which could further aid in response prediction for patients with BTC treated with immunotherapy. However, multicenter and larger sample studies are required to validate these results. Impact and implications Immunotherapy is an alternative for the treatment of advanced BTC, whereas tumour response is heterogeneous. In a post hoc analysis of the single-arm phase II clinical trial (NCT03486678), we found that CT radiomics features were associated with the tumour microenvironment and that IGR expression was a promising marker for tumour response and long-term survival. Clinical trial number Post hoc analysis of NCT03486678.

Abstract
Objective: To investigate the effect of individualized positive end expiratory pressure (PEEP) setting guided by chest electrical impedance tomography (EIT) on the incidence of hypoxemia in elderly patients undergoing robot-assisted radical prostatectomy in the post anesthesia care unit (PACU). Methods: From September 2020 to October 2021, sixty elderly patients, with the American Association of Anesthesiologists (ASA) of Grade Ⅰ to Ⅲ, who underwent selective robot-assisted radical prostatectomy under general anesthesia in the Cancer Hospital Affiliated to Fudan University were selected. The participants were divided into two groups by the minimum randomized grouping method: EIT-PEEP group (EP group, n=30) and fixed PEEP group (FP group, n=30). After completion of tracheal intubation and establishment of pneumoperitoneum flexion posture, the individualized PEEP setting was guided by EIT in EP group, and the PEEP setting in FP group was 5 cmH2O (1 cmH2O=0.098 kPa) to the end of operation. During the operation, the ventilation mode of pressure regulation volume control was adopted. The driving pressure, dynamic lung compliance (Cdyn), oxygenation index and hemodynamics were recorded at 5 min (T1), 30 min (T2), 60 min (T3) after PEEP setting and at the time of tracheal catheter removal (T4) in both groups. The primary end point was the incidence of hypoxemia in PACU after extubation. Results: The incidence of hypoxemia after extubation was 3.3% (1/30) in EP group and 26.7% (8/30) in FP group (P=0.030). The difference of driving pressure between the two groups at T2 [(13.1±2.4) cmH2O vs (14.9±2.9) cmH2O, P=0.012], T3 [(12.7±2.4) cmH2O vs (15.6±2.8) cmH2O, P<0.001] was statistically significant. In EP group, Cdyn was improved at T2 [(38.4±7.2) ml/cmH2O vs (31.9±5.2) ml/cmH2O, P=0.006] and T3 [(37.5±9.0) ml/cmH2O vs (30.4±5.9) ml/cmH2O, P=0.001]. In EP group, PaO2/FiO2 increased at T1 [(465.7±84.5) mmHg vs (383.5±58.0) mmHg, 1 mmHg=0.133 kPa, P<0.001], T2 [(504.7±105.8) mmHg vs (418.9±73.7) mmHg, P=0.001], T3 [(520.7±92.2) mmHg vs (423.2±90.7) mmHg, P<0.001], T4 [(368.7±42.0) mmHg vs (339.5±54.9) mmHg, P=0.024]. Conclusion: The individualized PEEP setting guided by EIT can reduce the incidence of hypoxemia in elderly patients undergoing robot assisted radical prostatectomy in PACU.

Abstract
Objective: To analyze the safety of an inactivated 2019-nCoV vaccine (Vero cell) in adults aged 60 years and older. Methods: A randomized, double-blind, placebo-controlled clinical study was conducted in May 2020 The eligible residents aged 60 and above were recruited in Renqiu city, Hebei Province. A total of 422 subjects (phase Ⅰ/Ⅱ:72/350) were enrolled. Two doses of the trial vaccine or placebo were randomly administered according to a 0 and 28-day immunization schedule. Subjects were randomly divided into two groups in Phase Ⅰ. Within each group, participants received vaccine or placebo in a ratio of 2∶1. Subjects were randomly divided into four groups in phase Ⅱ to receive low-dose, medium-dose, high-dose vaccine and placebo, respectively, in a ratio of 2∶2∶2∶1. A combination of regular follow-up and active reporting was used to observe adverse reactions within 28 days after vaccination, and compare the incidence rate of adverse reactions in the trial and control groups. Results: 422 subjects were (66.45±4.70) years old, and 48.82% were male (206/422). There were 100, 124, 124 and 74 patients enrolled into the low-dose, medium-dose, high-dose vaccine groups and the placebo group, respectively. One person without the vaccination was removed, and 421 participants who received at least one dose of vaccine were included in the safety analysis. Within 28 days after the first or second dose, a total of 20.67% (87/421) subjects had adverse reactions (both solicitation and non-solicitation). About 76 patients suffered grade 1 adverse reactions [18.05% (76/421)] and 22 patients suffered grade 2 adverse reactions [5.23% (22/421)]. No grade 3 or above adverse reactions occurred. A total of 19.71% (83/421) subjects had solicited adverse reactions. The most common grade 1 adverse reaction was injection site pain, followed by fever and fatigue. The most common grade 2 adverse reactions were fever and fatigue, followed by muscle pain and injection site redness. A total of 2.61% (11/421) subjects had unsolicited adverse reactions. A total of 1.66% (7/421) subjects had serious adverse events after vaccination, and no serious vaccine-related adverse events were reported. Conclusions: The inactivated SARS-CoV-2 vaccine is safe for people aged 60 years and above.

Abstract
Biliary tract cancer (BTC) is an uncommon and aggressive neoplasm, with most patients presenting in an advanced stage. Systemic chemotherapy is the limited treatment available but is unsatisfactory, while targeted therapy is still awaiting validation from clinical trials. Given the potential effect of immune checkpoint inhibitors (ICIs) in the treatment of BTC, this review aims to summarize the evidence-based benefits and predictive biomarkers for using inhibitors of cytotoxic T-lymphocyte-associated protein-4 (CTLA-4) ligand, or programmed cell death protein-1 and its ligand (PD-1 and PD-L1) as monotherapy or combined with other anti-tumor therapies, while also pointing out certain pitfalls with the use of ICIs which need to be addressed.

Abstract
Objective: To analyze clinical characteristics of intracranial vessel involvement in Takayasu's arteritis (TA). Methods: Retrospectively analyzed 135 hospitalized TA patients' clinical data in Beijing Anzhen Hospital from November 2012 to November 2018. Based on intracranial artery (IA) complicated or not, TA patients were divided into two groups:32 patients within involvement and 103 patients without involvement. The difference in comparison of imaging types, basic data and laboratory test were analyzed. Results: The proportion of TA patients with intracranial vascular involvement was 23.7% (32/135) and the most common site was internal carotid artery (intracranial segment) (59.4%, 19/32). The incidences of hypertension and coronary heart disease were significantly higher in TA patients with intracranial vascular involvement compared with the patients without intracranial involvement (46.9% vs 26.2%, 21.9% vs 6.8%, χ(2)=4.863, 4.460, all P<0.05). The rate of tocilizumab treatment in the intracranial vascular involved group was higher than that in the group without intracranial vascular involvement (40.6% vs 19.4%, χ(2)=5.945, P<0.05). The platelet count in patients with intracranial involvement group was significantly lower than that in patients without intracranial involvement group [(218±55)×10(9)/L vs (272±71)×10(9)/L, t=-3.570, P<0.01], while the hemoglobin [(130±17) vs (121±18) g/L, t=2.363, P<0.05] and triglyceride [1.22(0.75, 1.64) vs 0.92(0.63, 1.21) mmol/L, U=1 017.000, P<0.01] were significantly higher than those without intracranial vascular involvement. Moreover, coronary artery involvement presented more frequently in the intracranial vascular involved group than the group without intracranial vascular involvement (43.8% vs 14.6%, χ(2)=12.331, P<0.01). Logistic regression analysis showed that the incidence of intracranial vascular disease in TA patients with coronary artery involvement was 4 times higher than that in patients without coronary artery lesions (OR=3.965, 95%CI:1.584-9.926, P=0.003). Conclusion: The proportion of intracranial vascular involvement in TA is not rare, TA patients with cardiovascular risk factors should be considered to strengthen imaging examination of intracranial vessels.

Abstract
Objective: The main purpose of this paper is to evaluate the level of serum 25-hydroxyvitamin D (25-OH-D) and clinical significance in patients with Takayasu's Arteritis (TA). Methods: A total of 62 untreated TA patients (TA group) and 60 healthy people (control group) were enrolled. The level of serum 25-OH-D were measured and compared between groups. The correlations of 25-OH-D level with related indicators were analyzed. Results: Lower concentrations of serum 25-OH-D were detected in TA patients compared with healthy subjects[(11.8±4.7) μg/L versus (23.2±8.3) μg/L](P<0.001). In active stage group, the 25-(OH)-D level of TA were significantly lower than that in remission stage group[(10.5±4.3) μg/L vs (13.3±4.9) μg/L](P=0.021). In all patients with TA, serum 25-OH-D correlated negatively with interleukin (IL)-6 (r=-0.296, P=0.023). There was no correlation between serum 25-OH-D level and C-reactive protein , erythrocyte sedimentation rate , National Institutes of Health Score, Indian Takayasu Clinical Activity Score 2010, and anti-tumor necrosis factor (TNF)-alpha antibody. Conclusion: A high prevalence of vitamin D deficiency was observed in patients with TA. The serum 25-OH-D level were negatively correlated with IL-6.

Abstract
PURPOSE To evaluate the effect of low-intensity pulsed ultrasound(LIPUS) combined with triamcinolone acetonide on oral mucosal ulcer in syrian hamster in several ways, including healing time, contents of superoxide dismutase(SOD)and malondialdehyde (MDA). METHODS Sixty syrian hamsters were randomly divided into 5 groups, including a baseline group (containing a normal baseline group and a model baseline group, n=6) and 4 experimental groups (LIPUS processing and drug use group, LIPUS group, drug group and a normal control group without any processing, n=12). Four experimental groups and model baseline group were given oxygen free radicals to model the oral mucosal ulcer. At 24 h after the last treatment, the healing time of ulcer, content of SOD and MDA were compared between each group. SPSS 20.0 software package was used for statistical analysis. RESULTS Compared with LIPUS group,drug group and control group, the healing time of oral mucosal ulcer in LIPUS and drug combined group was shortened. At 24 h after the last treatment, the activity of SOD showed that the LIPUS and drug combined group[(2.32±0.30) U/mgprot] were significantly higher than the model baseline group[(1.48±0.29) U/mgprot], the LIPUS group[(1.83±0.15) U/mgprot], the drug group[(1.76±0.25) U/mgprot] and control group[(1.71±0.18) U/mgprot] (P<0.05). The results of MDA content showed that the LIPUS and drug combined group [(8.17±0.21) nmol/mgprot] were significantly lower than the model baseline group[(9.41±0.22) nmol/mgprot], the LIPUS group[(9.00±0.44) nmol/mgprot], the drug group [(9.04±0.43) nmol/mgprot] and control group[(9.03±0.46) nmol/mgprot] (P<0.05). After oral mucosal ulcer healing, the activity of SOD and MDA showed that the LIPUS and drug combined group, the LIPUS group, the drug group and control group were not significantly different from the normal baseline group (P>0.05). CONCLUSIONS Low-intensity pulsed ultrasound combined with triamcinolone acetonide can effectively improve the activity of SOD and reduce the contents of MDA in ulcerated tissues, and therefore accelerate the process of ulcer healing..

Abstract
Burkitt lymphoma (BL) is a highly malignant non-Hodgkin's lymphoma that is closely
related to the abnormal expression of genes. Familial acute myelogenous leukemia
related factor (FAMLF; GenBank accession No. EF413001.1) is a novel
gene that was cloned by our research group, and miR-181b is located in the intron of
the FAMLF gene. To verify the role of miR-181b and
FAMLF in BL, RNAhybrid software was used to predict target site
of miR-181b on FAMLF and real-time quantitative PCR (RQ-PCR) was
used to detect expression of miR-181b and FAMLF in BL patients, Raji
cells and unaffected individuals. miR-181b was then transfected into Raji and CA46
cell lines and FAMLF expression was examined by RQ-PCR and western
blotting. Further, Raji cells viability and proliferation were detected by MTT and
clone formation, and Raji cell cycle and apoptosis were detected by flow cytometry.
The results showed that miR-181b can bind to bases 21–42 of the
FAMLF 5′ untranslated region (UTR), FAMLF was
highly expressed and miR-181b was lowly expressed in BL patients compared with
unaffected individuals. FAMLF expression was significantly and
inversely correlated to miR-181b expression, and miR-181b negatively regulated
FAMLF at posttranscriptional and translational levels. A
dual-luciferase reporter gene assay identified that the 5′ UTR of
FAMLF mRNA contained putative binding sites for miR-181b.
Down-regulation of FAMLF by miR-181b arrested cell cycle, inhibited
cell viability and proliferation in a BL cell line model. Our findings explain a new
mechanism of BL pathogenesis and may also have implications in the therapy of
FAMLF-overexpressing BL.

Abstract
Atrazine is one of the most widely applied and persistent herbicides in the world. In view of limited information on the regional contamination of atrazine in soils in China, this study investigated the spatial distribution and environmental impacts of atrazine in agricultural soils collected from the Yangtze River Delta (YRD) as an illustrative analysis of rapidly developing regions in the country. The results showed that the concentrations of atrazine in the YRD agricultural soils ranged from <1.0 to 113 ng/g dry weight, with a mean of 5.7 ng/g, and a detection rate of 57.7 % in soils. Pesticide factory might be a major source for the elevated levels of atrazine in Zhejiang Province. The contamination of atrazine was closely associated with land use types. The concentrations and detection rates of atrazine were higher in corn fields and mulberry fields than in rice paddy fields. There was no significant difference in compositions of soil microbial phospholipids fatty acids among the areas with different atrazine levels. Positive relationship (R = 0.417, p < 0.05, n = 30) was observed between atrazine and total microbial biomass. However, other factors, such as soil type and land management practice, might have stronger influences on soil microbial communities. Human health risks via exposure to atrazine in soils were estimated according to the methods recommended by the US EPA. Atrazine by itself in all the soil samples imposed very low carcinogenic risks (<10-6) and minimal non-cancer risks (hazard index <1) to adults and children.

Abstract
The Convective Transport of Active Species in the Tropics (CONTRAST) experiment was conducted from Guam (13.5° N, 144.8° E) during January-February 2014. Using the NSF/NCAR Gulfstream V research aircraft, the experiment investigated the photochemical environment over the tropical western Pacific (TWP) warm pool, a region of massive deep convection and the major pathway for air to enter the stratosphere during Northern Hemisphere (NH) winter. The new observations provide a wealth of information for quantifying the influence of convection on the vertical distributions of active species. The airborne in situ measurements up to 15 km altitude fill a significant gap by characterizing the abundance and altitude variation of a wide suite of trace gases. These measurements, together with observations of dynamical and microphysical parameters, provide significant new data for constraining and evaluating global chemistry climate models. Measurements include precursor and product gas species of reactive halogen compounds that impact ozone in the upper troposphere/lower stratosphere. High accuracy, in-situ measurements of ozone obtained during CONTRAST quantify ozone concentration profiles in the UT, where previous observations from balloon-borne ozonesondes were often near or below the limit of detection. CONTRAST was one of the three coordinated experiments to observe the TWP during January-February 2014. Together, CONTRAST, ATTREX and CAST, using complementary capabilities of the three aircraft platforms as well as ground-based instrumentation, provide a comprehensive quantification of the regional distribution and vertical structure of natural and pollutant trace gases in the TWP during NH winter, from the oceanic boundary to the lower stratosphere.

Abstract
Tea (Camellia sinensis L.) is a thermophilic evergreen woody plant that has poor cold tolerance. The SAD gene plays a key role in regulating fatty acid synthesis and membrane lipid fluidity in response to temperature change. In this study, full-length SAD cDNA was cloned from tea leaves using rapid amplification of cDNA ends and polymerase chain reaction (PCR)-based methods. Sequence analysis demonstrated that CsSAD had a high similarity to other corresponding cDNAs. At 25°C, the CsSAD transcriptional level was highest in the leaf and lowest in the stem, but there was no obvious difference between the root and stem organs. CsSAD expression was investigated by reverse transcription-PCR, which showed that CsSAD was upregulated at 4° and -5°C. At 25°C, CsSAD was induced by polyethylene glycol, abscisic acid, and wounding, and a similar trend was observed at 4°C, but the mean expression level at 4°C was lower than that at 25°C. Under natural cold acclimation, the 'CsCr05' variety's CsSAD expression level increased before decreasing. The CsSAD expression level in variety 'CsCr06' showed no obvious change at first, but rapidly increased to a maximum when the temperature was very low. Our study demonstrates that CsSAD is upregulated in response to different abiotic conditions, and that it is important to study the stress resistance of the tea plant, particularly in response to low temperature, drought, and wounding.

Abstract
The spermidine synthase (SPDS) gene exists widely in all types of plants. In this paper, the codon usage of the SPDS gene from Camellia sinensis (CsSPDS) was analyzed. The results showed that the codon usage of the CsSPDS gene is biased towards the T-ended or A-ended codons, which is similar to that observed in 73 genes selected from the C. sinensis genome. An ENC-plot for 15 SPDS genes from various plant species suggested that mutational bias was the major factor in shaping codon usage in these genes. Codon usage frequency analysis indicated that there was little difference between the CsSPDS gene and dicot genomes, such as Arabidopsis thaliana and Nicotiana tabacum, but significant differences in codon usage were observed between the CsSPDS gene and monocot genomes, such as Triticum aestivum and Zea mays. Therefore, A. thaliana and N. tabacum expression systems may be more suitable for the expression of the CsSPDS gene.

Abstract
Numerous studies have evaluated the association between the human interleukin-10 gene -592C>A polymorphism and gastric cancer risk. However, the results have been inconsistent. This meta-analysis was designed to resolve these controversies. Systematic searches of the electronic databases Embase, PubMed, and Google Scholar were performed to identify relevant studies. A meta-analysis was performed to examine the association between the interleukin-10 gene -592C>A polymorphism and gastric cancer risk. Odds ratios (OR) and its 95% confidence intervals (CI) were used for statistical analysis. Twelve studies were included in the meta-analysis, which included 2116 gastric cancer cases and 4077 controls. No significant association was found between the interleukin-10 gene -592C>A polymorphism and gastric cancer risk in total population analysis. In stratified analysis, a significant association was found in the Asian subgroup (AA vs AC: OR = 0.79, 95%CI = 0.64-0.98; dominant model: OR = 1.26, 95%CI = 1.04-1.57), and no significant association was observed among Caucasians. In addition, the corresponding pooled ORs were not substantially altered after excluding one study that deviated from Hardy-Weinberg equilibrium in the control group. This meta-analysis supports an association between the interleukin-10 gene -592C>A polymorphism and gastric cancer risk in Asians but not in Caucasians. Further large and well-designed studies are needed to confirm these conclusions.

Abstract
The present study was designed to investigate the protective effects of 4-guanidino-n-butyl syringate (leonurine), a compound in Herba Leonuri (HL) on ischemic rat heart to determine the protective mechanisms associated with ischemic rat hearts. Rat heart ischemia was induced by ligation of the left coronary artery. Creatine kinase (CK) and lactate dehydrogenase (LDH) in plasma and superoxide dismutase (SOD) activity in heart homogenates were measured. We found leonurine significantly decreased levels of LDH and CK activities in plasma. This observation corresponded with decreased infarct size of ischemic rat heart induced by ligation of the left coronary artery. Moreover, the mRNA expression of the pro-apoptotic gene Bax was significantly down-regulated by 0.68-fold (p < 0.05) and the anti-apoptotic gene Bcl-2 was up-regulated by 1.41-fold (p < 0.05) in the leonurine treated groups as compared with acute myocardium ischemia (MI) controls measured by RT-PCR. Correspondingly, Bcl-2 and Bax protein levels detected by Western blotting coincided with gene expression levels. In addition, the mRNA expression level of the antioxidant enzyme Mn-SOD was significantly increased 1.23-fold (p < 0.05) and this finding corresponded with an observed increase in SOD activity and also with a committed decrease in lipid peroxidation. Taken together, our results demonstrated that leonurine attenuated myocardium injury during MI via antioxidative and anti-apoptotic effects and leonurine might become a useful adjuvant cardioprotective agent.

Abstract
Paeonol (2'-hydroxy-4'-methoxyacetophenone), the main active compound of the radix of Paeonia suffruticosa, has been reported to have a beneficial effect in prevention and treatment of cardiovascular diseases. Vascular cell adhesion molecule-1 (VCAM-1), plays a crucial role in case of early inflammatory responses, including atherosclerosis. In this study, we investigated the effect of paeonol on TNF-alpha-induced VCAM-1 expression in rat aortic endothelial cells (RAECs). The VCAM-1 expression in paeonol treated RAECs was measured. Paeonol inhibited TNF-alpha-induced VCAM-1 expression in a concentration-dependent manner. TNF-alpha induced p38 and extracellular signal-regulated kinase 1/2 (ERK1/2) activities that contributed to VCAM-1expression was obviously attenuated after pre-treating RAECs with paeonol. The decrease of VCAM-1 expression by paeonol pretreatment led to a reduction of monocytes adhesion to RAECs. Taken together, our results demonstrated that paeonol inhibited VCAM-1 expression by the attenuation of p38 and ERK1/2 signal transduction pathways. We concluded that paeonol had the potential therapeutic development for use in anti-inflammatory and vascular disorders.

Abstract
In male Drosophila, histone H4 acetylated at Lys16 is enriched on the X chromosome, and most X-linked genes are transcribed at a higher rate than in females (thus achieving dosage compensation). Five proteins, collectively called the MSLs, are required for dosage compensation and male viability. Here we show that one of these proteins, MSL1, interacts with three others, MSL2, MSL3 and MOF. The latter is a putative histone acetyl transferase. Overexpression of either the N- or C-terminal domain of MSL1 has dominant-negative effects, i.e. causes male-specific lethality. The lethality due to expression of the N-terminal domain is reduced if msl2 is co-overexpressed. MSL2 co-purifies over a FLAG affinity column with the tagged region of MSL1, and both MSL3 and MOF co-purify with the FLAG-tagged MSL1 C-terminal domain. Furthermore, the MSL1 C-terminal domain binds specifically to a GST-MOF fusion protein and co-immunoprecipitates with HA-tagged MSL3. The MSL1 C-terminal domain shows similarity to a region of mouse CBP, a transcription co-activator. We conclude that a main role of MSL1 is to serve as the backbone for assembly of the MSL complex.
