In this study,nine hybridoma cells secreting monoclonal antibodies against deltamethrin were prepared,and the monoclonal antibody 4D4E11 with best sensitivity was selected to develop indirect enzyme-linked immunosorbent assay (ic-ELISA) and gold nanoparticle-based lateral flow immunoassay (LFIA) for detection of deltamethrin. The optimal working buffer for ic-ELISA was 0.01 mol/L phosphate buffer (pH 7.4) containing 0.2 mol/L NaCl and 20% methanol,while 0.01 mol/L phosphate buffer (pH 7.4) containing 1 mol/L NaCl,5‰Tween-20 and 10%methanol for LFIA. Under the optimal conditions,the half inhibition concentration (IC50) and limit of detection (IC10) of ic-ELISA were 10.60 ng/mL and 1.43 ng/mL respectively,and the limit of detection of the developed LFIA was 0.5μg/mL. The developed ic-ELISA and LFIA showed no cross-reactivities (CRs) with eight kinds of analogues of deltamethrin,which indicated the excellent specificity of proposed immunoassays. The average recoveries of the ic-ELISA in spiked tomato,cabbage and lettuce samples were 79.8%-92.6%with relative standard deviations of 0.8%-5.5%. The detection results of LFIA were consistent with the spiked concentrations in the range of 1-5 mg/kg. Meanwhile,the results of ic-ELISA and LFIA showed close correlation with high performance liquid chromatography (HPLC) in the test of blind lettuce samples. The experimental results demonstrated that the two immunoassays proposed here were suitable for rapid detection of deltamethrin with high sensitivity and high accuracy.

Objective To establish an animal model of sparganosis mansoni through oral administration of Cyclops infected with procercoids. Methods Domestic cats were infected with Sparganum mansoni under laboratory conditions, and fresh cat stool samples were collected, washed in dechlorinated water, and filtered. Spirometra mansoni eggs were collected and prepared into suspensions. Twenty C57BL/6j mice were randomly divided into the experimental group (n = 15) and the control group (n = 5). Wild Cyclops were infected with Spirometra mansoni coracidia to allow 3 to 5 procercoids in each Cyclop. Then, each mouse in the experimental group was given 15 Cyclops infected with procercoids by gavage, while mice in the control group were orally administered with the same volume of dechlorinated water. All mice were sacrificed after 5 months, and dissected, and suspicious Sparganum mansoni worms were collected. The serum specific IgG antibody against Sparganum mansoni was measured in mice using enzyme-linked immunosorbent assay (ELISA). Genomic DNA was isolated from suspicious Sparganum mansoni worms, and the specific Sparganum mansoni cytochrome oxidase I (COI) gene was amplified using PCR assay. Results Among the 15 mice in the experimental group, six were positive for the serum specific IgG antibody against Sparganum mansoni, and milky white worms were found and collected from the subcutaneous regions of 4 out of 6 mice. Only one worm was detected in each mouse, and the worm morphology was similar to Sparganum mansoni. Capillary electrophoresis of the PCR amplification products of COI gene presented a specific band with 151 bp in size, and sequencing analysis revealed 100% homology with Sparganum mansoni. Conclusions A mouse model of sparganosis mansoni is successfully created through oral administration of Cyclops infected with Spirometra mansoni procercoids.

ObjectiveTo explore the effects of three kinds of microbial fertilizers on the growth, yield, quality, and cadmium (Cd) accumulation of Chuanxiong Rhizoma (CX). MethodTaking CX seeds as materials, field experiments were carried out in the main producing areas, Pengzhou and Meishan. The samples were collected during the harvesting period, and the agronomic characters and yield were determined. The contents of extract, volatile oil, and ferulic acid were analyzed by the collection method of Chinese Pharmacopoeia (2020 edition). The content of Cd was determined by inductively coupled plasma-mass spectrometry (ICP-MS). Data were processed by difference significance analysis, correlation analysis and cluster analysis. ResultThree kinds of microbial fertilizers with appropriate concentrations could promote the growth of CX. In terms of yield and quality, the treatment of Jinwuzong (1.50 ton/hm2, 1 ton=1 000 kg, the same below) and Cuijingyuan (1.5 L·hm-2) could increase the yield of medicinal materials by 0.92%-46.34%, while Cuijingyuan (1.8 L·hm-2) and Shenchu (15, 30 kg·hm-2) could increase the water-soluble extract of CX by 0.06%-18.79%, of which Cuijingyuan (1.8 L·hm-2) was significantly increased (P<0.01). The alcohol-soluble extract of CX treated with Jinwuzong (0.75, 1.50, 2.25 ton/hm2), Shenchu (15, 45 kg·hm-2), and Cuijingyuan (1.2 L·hm-2) decreased significantly by 3.51%-22.94% (P<0.01). The content of ferulic acid in CX treated with Jinwuzong (1.50 ton/hm2) and Shenchu (30 kg·hm-2) decreased by 2.14%-30.56%. Three kinds of microbial fertilizers had little effect on the content of volatile oil in CX. In the aspect of Cd enrichment, the concentration of Cd in rhizosphere soil of CX was increased by 11.33%-76.36% (P<0.01) after the treatment of Jinwuzong (0.75, 1.50, 2.25 ton/hm2), Shenchu (15, 30, 45 kg·hm-2) and Cuijingyuan (1.2 L·hm-2). However, the Cd enrichment coefficient of CX reduced by 2.58%-48.38%, the Cd content and Cd accumulation of CX decreased respectively by 9.54%-25.96% and 9.34%-18.88% via Jinwuzong (0.75 ton/hm2) and Cuijingyuan (1.8 L·hm-2). ConclusionThree kinds of microbial fertilizers have a certain positive effect on the growth, substance accumulation, and reduction of Cd content in medicinal parts of CX, and the changes of each index are affected by the producing area and treatment method. Based on the comprehensive analysis of various indicators, Jinwuzong (0.75, 1.50 ton/hm2) can better adapt to the rhizosphere soil micro-ecological environment of CX, it can effectively reduce the content of Cd on the premise of guaranteeing the yield and quality of CX.

OBJECTIVE Cerebral ischemia or ischemic stroke is due to insufficient blood supply to the brain, which causes hypoxia or ischemia in some areas. This work aimed to quantify the minerals and heavy metals in Qishiwei Zhenzhu pill in vivo and in vitro, analyze its effect on the types and abundance of intestinal flora, and study its mechanism on inflammation and apoptosis pathways as a treatment for cerebral ischemia. METHODS Microwave digestion and induc?tively coupled plasma mass spectrometry (ICP-MS) were used to determine the minerals and heavy metals in 10 batches of Qishiwei Zhenzhu pill in vitro. With the use of the middle cerebral artery obstruction (MCAO) model, ICP-MS was applied to determine the content of minerals and heavy metals in hepatic portal vein blood, abdominal aortic blood, brain, liver, kidney, hair, urine and feces at different time periods. On this model, the ileum, cecum, and colon tissues were tested for intestinal pathology, and 16S rRNA was used for sequencing. Species taxonomy, α diversity, and spe?cies microbial composition and structure analysis were also performed. Polymerase chain reaction and Western blotting were employed to determine the mRNA and protein expression of p38 MAPK, caspase-3, IL-1β and TNF-α in the isch?emic brain tissues of rats. RESULTS The average content of heavy metals in the 10 batches of Qishiwei Zhenzhu pill samples is in the descending order Hg>Cu>Pb. Significant differences in the metal elements are found among Qishiwei Zhenzhu pill from different manufacturers but not among the different batches of the same manufacturer. An extremely low content of heavy metals are absorbed into the blood or accumulated in the brain, liver, kidney, and other tissues. Stool is the main excretion route of minerals and heavy metals from Qishiwei Zhenzhu pill. This medicine helps repair the intestinal mucosa in MCAO rats. At the phylum level, it can regulate the abundance of Firmicutes and Proteobacteria in the intestinal flora of rats with cerebral ischemia. At the genus level, it can adjust the abundance of Escherichia Shigella. At the species level, it can adjust the abundance of Lactobacillus yoelii and Lactobacillus reuteri. Cluster classification results show that Qishiwei Zhenzhu pill can improve the intestinal flora of rats with cerebral ischemia, reduce the mRNA and protein expression of caspase-3 and IL-1βin rat brain tissues, and have a tendency to decrease the mRNA expres?sion of p38 MAPK and TNF-α. CONCLUSION Quantifying the minerals and heavy metals in Qishiwei Zhenzhu pill in vivo and in vitro will help improve their quality standards. Minerals and heavy metals are mainly excreted in feces, accumu?late in extremely low levels in various tissues, and do not damage the intestinal mucosa. The effective material basis of Qishiwei Zhenzhu pill in treating cerebral ischemia may be related to their Li, Cr, and Cd elements. These pills can improve the environment of intestinal flora, and their mechanism of treatment for cerebral ischemia may be related to the down-regulation of IL-1βinflammatory factor and inhibition of cell apoptosis.

Objective:
Several COVID-19 patients have overlapping comorbidities. The independent role of each component contributing to the risk of COVID-19 is unknown, and how some non-cardiometabolic comorbidities affect the risk of COVID-19 remains unclear.
Methods:
A retrospective follow-up design was adopted. A total of 1,160 laboratory-confirmed patients were enrolled from nine provinces in China. Data on comorbidities were obtained from the patients' medical records. Multivariable logistic regression models were used to estimate the odds ratio (
Results:
Overall, 158 (13.6%) patients were diagnosed with severe illness and 32 (2.7%) had unfavorable outcomes. Hypertension (2.87, 1.30-6.32), type 2 diabetes (T2DM) (3.57, 2.32-5.49), cardiovascular disease (CVD) (3.78, 1.81-7.89), fatty liver disease (7.53, 1.96-28.96), hyperlipidemia (2.15, 1.26-3.67), other lung diseases (6.00, 3.01-11.96), and electrolyte imbalance (10.40, 3.00-26.10) were independently linked to increased odds of being severely ill. T2DM (6.07, 2.89-12.75), CVD (8.47, 6.03-11.89), and electrolyte imbalance (19.44, 11.47-32.96) were also strong predictors of unfavorable outcomes. Women with comorbidities were more likely to have severe disease on admission (5.46, 3.25-9.19), while men with comorbidities were more likely to have unfavorable treatment outcomes (6.58, 1.46-29.64) within two weeks.
Conclusion
Besides hypertension, diabetes, and CVD, fatty liver disease, hyperlipidemia, other lung diseases, and electrolyte imbalance were independent risk factors for COVID-19 severity and poor treatment outcome. Women with comorbidities were more likely to have severe disease, while men with comorbidities were more likely to have unfavorable treatment outcomes.
