ABSTRACT
Bispecific antibodies (BsAb) are special antibodies that can bind to two different antigenic epitopes at the same time, and their diverse forms provide the basis for different effects. In 2021, amivanamab was approved to treat metastatic or surgically unresectable non-small cell lung cancer patients with epidermal growth factor receptor (EGFR) 20 exon insertion mutation who experience tumor progression during or after platinum doublet chemotherapy. BsAb has made great progress in the treatment of solid tumors, especially lung cancer. This article reviews the structural form, mechanism and research progress of BsAb in the field of lung cancer.
ABSTRACT
OBJECTIVE To investigate the effects of Compound troxerutin and poreine cerebroside injection on the activity of cytochrome P450 （CYP450） enzyme in vivo and in vitro. METHODS Human liver microsomes were incubated with Compound troxerutin and poreine cerebroside injection （volume fraction 0.05%-10%） and the specific probe substrates of CYP1A2， CYP2B6， CYP2C8， CYP2C9， CYP2C19， CYP2D6 and CYP3A4 for 30 min. The production of corresponding metabolites was detected by ultra-high performance liquid chromatography-tandem mass spectrometry （UPLC-MS/MS）， and the half inhibitory concentration （IC50） was calculated. The relative mRNA expression （i.e. induction multiple） of CYP450 enzyme was determined by real-time fluorescence quantitative PCR after human primary hepatocytes were incubated with Compound troxerutin and poreine cerebroside injection （volume fraction 0.05%-10%） or 3 positive inducers of CYP1A2， CYP2B6， CYP3A4 for 48 hours. Male SD rats were randomly divided into control group （normal saline+probe substrates of CYP1A2， CYP2B6， CYP2C8， CYP2C9， CYP2C19， CYP2D6， CYP3A4 8， 2， 1， 1， 10， 10， 8 mg/kg） and experimental group （Compound troxerutin and poreine cerebroside injection 0.9 mL/kg+probe substrates of CYP1A2， CYP2B6， CYP2C8， CYP2C9， CYP2C19， CYP2D6， CYP3A4 8， 2， 1， 1， 10，10， 8 mg/kg）， with 6 rats in each group. The pharmacokinetic parameters of probe substrates were detected by UPLC-MS/MS and Cocktail probe drug method. RESULTS After the lzqpharm@126.com treatment of 0.05%-10% Compound troxerutin and poreine cerebroside injection， the activities of CYP2B6， CYP2C8 and CYP2C19 in human liver microsomes had no significant change， and IC50 could not be fitted； IC50 of CYP1A2， CYP2C9， CYP2D6 and CYP3A4 were 419.90%， 97.78%， 176.00%， 19.42%， respectively. After the treatment of 0.05%-10% Compound troxerutin and poreine cerebroside injection， the average induction multiple of CYP3A4 mRNA in human primary hepatocytes （No. MHK） was 4.88 （and the average induction multiples of 2 concentration points were higher than 2）. After the treatment of Compound troxerutin and poreine cerebroside injection， AUC0－t and AUC0－∞ of CYP2C8， CYP2C9 and CYP2C19 substrates were increased significantly， CL of CYP2C8 and CYP2C19 substrates were decreased significantly， while t1/2 of CYP2C9 substrate was prolonged significantly （P＜0.05）. CONCLUSIONS Compound troxerutin and poreine cerebroside injection has no obvious inhibitory effect on CYP1A2， CYP2B6， CYP2C8， CYP2C9， CYP2C19， CYP2D6 and CYP3A4 in human liver microsomes in vitro， but can induce the mRNA expression of CYP3A4 in human primary hepatocytes in vitro， and can inhibit the activities of CYP2C8， CYP2C9 and CYP2C19 in rats in vivo.
ABSTRACT
Asymptomatic individuals carrying SARS-CoV-2 can transmit the virus and contribute to outbreaks of COVID-19, but it is not yet clear how the proportion of asymptomatic infections varies by age and geographic location. Here we use detailed surveillance data gathered during COVID-19 resurgences in six cities of China at the beginning of 2021 to investigate this question. Data were collected by multiple rounds of city-wide PCR test with detailed contact tracing, where each patient was monitored for symptoms through the whole course of infection. We find that the proportion of asymptomatic infections declines with age (coefficient =-0.006, P<0.01), falling from 56% in age group 0-9 years to 12% in age group >60 years. Using an age-stratified compartment model, we show that this age-dependent asymptomatic pattern together with the age distribution of overall cases can explain most of the geographic differences in reported asymptomatic proportions. Combined with demography and contact matrices from other countries worldwide, we estimate that a maximum of 22%-55% of SARS-CoV-2 infections would come from asymptomatic cases in an uncontrolled epidemic based on asymptomatic proportions in China. Our analysis suggests that flare-ups of COVID-19 are likely if only adults are vaccinated and that surveillance and possibly control measures among children will be still needed in the future to contain epidemic resurgence.
ABSTRACT
Objective:To systematically evaluate the relationship between sedentary behavior (SB) and the risk of developing gestational diabetes mellitus (GDM).Methods:PubMed, Medline, EMBASE, CINAHL, the Cochrane Library, the Rehabilitation & Sports Medicine Source, the Sedentary Behavior Research Database (SBRD), Wanfang Database, the China Journal full-text database, and the China Biomedical Literature Database were searched for cohort studies, case-control studies, and cross-sectional studies concerning the risk of SB and GDM from the establishment of the database to January 2021. Two researchers screened the literature, extracted data, evaluated the quality of the data according to the inclusion and exclusion criteria, and, finally, produced a descriptive analysis of the results.Results:A total of 11 studies were included, including eight cohort studies, two cross-sectional studies, and one case-control study. The overall quality of the studies was moderate. The prevalence of GDM was 5.04%-26.81%, and the prevalence of SB before and during pregnancy was 39.47%-40.21% and 28.86%-93.50%, respectively. In terms of the prevalence of SB before pregnancy, four moderate-quality studies reported no association with GDM risk. In terms of SB during pregnancy, four moderate-quality studies reported no association with GDM risks, and four studies (one of high quality and three of moderate quality) reported an association with GDM risks, two of which focused on the second trimester. There was considerable heterogeneity between studies on the diagnosis of GDM and SB.Conclusion:SB before pregnancy is not associated with the risk of GDM, while the relationship between SB and the risk of GDM is unclear, but the level of SB in the second trimester of pregnancy may be positively associated with the risk of GDM.

ABSTRACT
Objective:To analyze the characteristics of total cerebral small vessel disease (CSVD) burden in octogenarians with CSVD and to investigate its correlation with serum uric acid.Methods:From January 2019 to December 2020, patients with CSVD diagnosed by 3.0 T magnetic resonance imaging (MRI) in Departments of Neurology and Departments of Geriatrics, Liaoning Jinqiu Hospital were enrolled retrospectively. The patients were scored and grouped according to the total CSVD burden assessment standard. Ordered logistic regression analysis was used to investigate the independent influencing factors of the total CSVD burden score, and the Spearman rank correlation method was used to conduct the correlation analysis between serum uric acid and the total CSVD burden score. Results:A total of 217 octogenarians with CSVD were enrolled in the study. Their age was 87.3±4.5 years, 150 were males (69.1%), and their median serum uric acid was 313.0 μmol/L. The total CSVD burden score: 50 patients (23.1%) in 1-point group, 79 (36.4%) in 2-point group, 68 (31.3%) in 3-point group, and 20 (9.2%) in 4-point group. The imaging subtypes of CSVD were mainly asymptomatic lacunar infarcts (ALIs; 98.2%) and white matter hyperintensities (WMHs; 77.0%). The CSVD subtype combination was different between different total CSVD burden score groups. There were only two subtypes in the 1-point group, mainly ALIs (92.0%), and WMHs accounted for only 8.0%. Four subtypes could be observed in other groups, among which ALIS+ WMHs mixed subtype (100% in the 3-point group and the 4-point group) accounts for the highest proportion. The detection rates of cerebral microbleeds (CMBs) and enlarged perivascular spaces (EPVS) increased significantly with the increase of the total CSVD burden score. The 3-point group was 44.1% and 55.9% respectively. Univariate analysis showed that there were significant differences in age, male, hypertension, coronary heart disease, serum uric acid level, high-density lipoprotein cholesterol and the highest quartile of serum uric acid between total CSVD burden score groups ( P<0.05). Multinomial ordinal logistic regression analysis showed that there was significant independent correlation between age (odds ratio 1.074, 95% confidence interval 1.013-1.140; P=0.017), serum uric acid (odds ratio 1.005, 95% confidence interval 1.000-1.009; P=0.032) and the total CSVD burden score. Spearman rank correlation analysis showed that there was a positive correlation between serum uric acid and the total CSVD burden score ( r=0.153, P=0.024). Conclusions:ALIs and WMHs are most common in octogenarians with CSVD. Four subtypes were observed in each group ≥2, and the proportion of EPVS and CMBs also increases with the increase of the total CSVD burden score. There is an independent correlation between serum uric acid and the total CSVD burden in the octogenarians.
ABSTRACT
In this study,we developed a novel on-line solid phase extraction (SPE)-ultra-high-performance liquid chromatography tandem mass spectrometry (UHPLC-MS/MS)-based analytical method for simulta-neously quantifying 12 illicit drugs and metabolites (methamphetamine,amphetamine,morphine,co-deine,6-monoacetylmorphine,benzoylecgonine,3,4-methylenedioxymethamphetamine,3,4-methylenedioxyamphetamine,cocaine,ketamine,norketamine,and methcathinone) and cotinine(COT) in wastewater samples.The analysis was performed by loading 2 mL of the sample onto an Oasis hydrophilic-lipophilic balance cartridge and using a cleanup step (5％ methanol) to eliminate interference with a total run time of 13 min.The isotope-labeled internal standard method was used to quantify the target substances and correct for unavoidable losses and matrix effects during the on-line SPE process.Typical analytical characteristics used for method validation were sensitivity,linearity,precision,repeatability,recovery,and matrix effects.The limit of detection (LOD) and limit of quantification (LOQ)of each target were set at 0.20 ng/L and 0.50 ng/L,respectively.The linearity was between 0.5 ng/L and 250 ng/L,except for that of COT.The intra-and inter-day precisions were ＜10.45％ and 25.64％,respec-tively,and the relative recovery ranged from 83.74％ to 162.26％.The method was used to analyze various wastewater samples from 33 cities in China,and the results were compared with the experimental re-suits of identical samples analyzed using off-line SPE.The difference rate was between 19.91％and-20.44％,and the error range could be considered acceptable.These findings showed that on-line SPE is a suitable alternative to off-line SPE for the analysis of illicit drugs in samples.
ABSTRACT
@#A quantitative analysis method based on solid phase extraction-ultra performance liquid chromatography-tandem mass spectrometry (SPE-UPLC-MS/MS) for simultaneous determination of illicit drugs and their metabolites in wastewater was established. Samples filtered at pH of 2 and spiked with internal standard were loaded to Oasis Prime MCX cartridges for solid-phase extraction. The samples were washed with 4 mL of methanol and eluted with 4 mL of 5% ammonia in acetonitrile before reconstituting with 0.1% formic acid/water solution. ZORBAX Eclipse Plus C18 column was used for chromatography, and gradient elution was performed with 0.1% formic acid/water solution and acetonitrile as mobile phase. The samples were then detected by electrospray ionization (ESI) in positive ion mode, and multiple reaction monitoring mode (MRM) was adopted for quantitative analysis. All analytes had a good linear relationship (r ≥ 0.993 2) within the range of their respective standard curve; the limit of quantification was 1 ng/L (except amphetamine at 2.5 ng/L); the extraction recovery ranged from 82.13% to 99.96%; and the intra- and inter-day precisions were less than 9.43%. The method is accurate, reliable and reproducible, and is suitable for the quantitative determination of illicit drugs and their metabolites in wastewater and can provide an analytical method for real-time monitoring of drug abuse.
ABSTRACT
Objective@#This study aims to analyze factors associated with lymphovascular space invasion (LVSI) and evaluate the prognostic significance of LVSI in Chinese endometrioid endometrial cancer (EEC) patients. @*Methods@#Five-hundred eighty-four EEC patients undergoing surgery in our center from 2006 to 2016 were selected for analysis. Univariate analysis and multivariate logistic regression were used to examine relevant factors of LVSI. To evaluate the prognostic role of LVSI, survival analyses were conducted. In survival analyses, both multivariate Cox regression and propensity score matching were used to control the confounders. @*Results@#The incidence of LVSI was 12.16% (71/584). Diabetes history (p=0.021), lymph node metastasis (p=0.005), deep myometrial invasion (p<0.001) and negative PR expression (p=0.007) were independently associated with LVSI. Both Kaplan-Meier method and univariate Cox regressions showed LVSI negative and positive cases had similar tumor-specific survival (TSS) and disease-free survival (DFS). After adjusting for the influence of adjuvant therapy and other clinicopathological factors with multivariate Cox regressions, LVSI still could not bring additional survival risk to the patients (p=0.280 and p=0.650 for TSS and DFS, respectively). This result was verified by Kaplan-Meier survival analyses after propensity score matching (p=0.234 and p=0.765 for TSS and DFS, respectively). @*Conclusion@#LVSI does not significantly compromise the survival outcome of Chinese EEC patients.
ABSTRACT
The morbidity and mortality of lung cancer are the highest in China, and the non-small cell lung cancer(NSCLC) is the first one, accounting for about 80% of lung cancer.NSCLC includes squamous cell carcinoma, adenocarcinoma, etc.Because of the slow growth of lung cancer cells and the late diffusion and metastasis, most of the patients were in late stage and lost the best period of surgical treatment.In recent years, molecular targeted therapy for specific genes has become an important strategy for the treatment of NSCLC.Multiple target genes, such as EGFR, KRAS, BRAF and EML4-ALK have been identified.This article reviews the related driving genes and molecular targeted therapy of NSCLC, expecting to be helpful to the individualized treatment of advanced NSCLC patients.

ABSTRACT
Peritoneal metastasis is one of the most frequent metastatic patterns of advanced gastric cancer, but the mechanism underlying remains unclear. The 'seed and soil’ theory is now well recognized for peritoneal metastasis of gastric cancer at present. The combination of various cells, extracellular matrix, and ascites components within the abdominal cavity provide a suitable microenvironment for the plantation, infiltra-tion, growth and metastasis of gastric cancer cells. Fully under-standing of peritoneal microenvironment will help to diagnose the peritoneal metastasis of gastric cancer and tumor recurrence, and provide theoretical basis for the development of drugs targeting peritoneal microenvironment. The authors review the main cell formation, ascites and immune microenvironment involved in the formation of the peritoneal microenvironment based on relevant literatures at home and abroad, and investigate the relationship between peritoneal microenvironment and peritoneal metastasis of gastric cancer.

ABSTRACT
Hepatic ischemia-reperfusion injury has always been a difficult problem in liver transplantation and liver tumor resection. The involvement of multiple mechanisms makes it particularly complex, among which energy expenditure during ischemia and oxidative stress induced by reperfusion are the main mechanisms leading to hepatic ischemia-reperfusion injury and may cause cell death and even liver failure. Silent information regulators are a class of nicotinamide adenine dinucleotide-dependent deacetylases which can lead to deacetylation of transcription factors including histones and nonhistones, and they are playing an important regulatory role in cell apoptosis, inflammatory response, energy balance, and oxidative stress. There are 7 types of silent information regulators in mammals, i.e., Sirt1-Sirt7, among which Sirt1 can reduce hepatocyte stress, regulate cell metabolic pathways, and thus alleviate the degree of hepatic ischemia-reperfusion injury through various signaling pathways. This article reviews the role of Sirt1-related signaling pathways in hepatic ischemia-reperfusion injury.

ABSTRACT
Diabetes is a significant public health problem that can be treated with insulin therapy; however, therapies designed to cure diabetes are limited. The goal of the current study was to assess the potential for curative treatment of diabetes using adipose-derived stem cells (ADSCs). To achieve this goal, the differentiation of rat ADSCs into pancreatic islet-like cells induced by coculture with pancreatic adult stem cells (PASCs) was characterized. Differentiation of ADSCs into islet-like cells induced by coculturing was determined morphologically, as well as by the assessment of islet cell markers using dithizone staining, immunohistochemistry, RT-PCR, qPCR, and western blotting. The results showed that ADSCs formed islet-like round cell masses after coculture with PASCs. These differentiated cells were shown to be positive for islet cell markers, including dithizone incorporation; PDX1, CK19 and Nestin by immunohistochemistry, and insulin, PDX1 and glucagon expression by RT-PCR. Differentiated ADSCs induced by coculturing also expressed insulin at the mRNA and protein level, with the level of insulin mRNA expression in cocultured ADSCs being 0.05 times greater than that of PASCs (P < 0.05). Taken together, our results demonstrate that ADSCs can be induced to differentiate into islet-like cells by coculture with PASCs; thus these cells can be used for transplantation, providing a theoretical foundation for the treatment of diabetes using this approach.
