Objective:To retrospectively analyze the feasibility of undergoing day surgery at 3rd week after infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in children.Methods:The clinical data from children who underwent day surgery from November 1, 2022 to February 28, 2023, with operation time ≤1 h, of American Society of Anesthesiologists Physical Status classification Ⅰ or Ⅱ, regardless of gender, aged≤14 yr, with body mass index of 10-30 kg/m 2, were divided into SARS-CoV-2 group and control group according to whether the children had been infected with the SARS-CoV-2. The main outcome measure was the incidence of respiratory system-related complications within 30 days after surgery. Secondary outcome measures included the rate of unplanned ventilation, delayed discharge and secondary admission within 30 days after surgery. Preoperative creatine kinase isoenzyme (CK-MB), aspartate aminotransferase (AST), alanine aminotransferase (ALT), hemoglobin (Hb), white blood cell count, C-reactive protein (CRP) level, grade of oropharyngeal mucosa inflammation, operation time, emergence time, intraoperative respiratory depression, laryngeal spasm, hypoxemia, hypotension, incidence of sinus bradycardia and rate of additional rescue drugs were recorded. Results:There were 337 cases in SARS-CoV-2 group and 1 396 cases in control group. Compared with control group, CK-MB concentrations were significantly increased, and the Hb concentration was decreased before surgery in SARS-CoV-2 group ( P<0.05). There were no statistically significant differences in the incidence of respiratory system-related complications, unplanned ventilation, delayed discharge and rate of postoperative secondary admission, preoperative AST and ALT concentrations, white blood cell count, CRP concentrations, grade of oropharyngeal mucosa inflammation, operation time, intraoperative respiratory depression, laryngeal spasm, hypoxemia, hypotension, incidence of sinus bradycardia, rate of additional rescue drugs and emergence time between the two groups ( P>0.05). Conclusions:Feasibility of undergoing day surgery is good at the third week after being infected with the SARS-CoV-2 in children.

Objective:To investigate the CLEC3B protein of differentially expressed proteins(DEPs)in serum of normal persons and patients with sepsis,and explore the possibility that target C-type lectin domain family 3 member B(CLEC3B)protein was used as molecular markers of sepsis.Methods:Peripheral bloods of 10 healthy persons and 18 patients with sepsis were collected,and the data of peripheral serum proteins were collected by data independent acquisition(DIA)method.The data were uploaded to iDEP online platform to analyze the DEPs in peripheral blood of patients with sepsis.Bioinformatics analysis of these DEPs was conducted to screen out the key proteins of sepsis.Enzyme linked immunosorbent assay(ELISA)was used to verify and plot the receiver operating characteristic(ROC)curves of key proteins.Results:A total of 138 differentially expressed proteins(DEPs)were screened out by using proteomics analysis,of which 34 kinds of proteins were significantly down-regulated and 104 kinds of proteins were significantly up-regulated.DEPs mostly concentrated in cellular processes,biological regulation,biological process regulation,participating binding,catalytic activation,molecular function regulation,immune system,signal transduction and so on.A protein-protein interaction network was constructed by DEPs,which screened out the key protein CLEC3B.ELISA results showed that the CLEC3B protein concentration[(297.73±22.00)ng/mL]of patients in the sepsis group was significantly lower than that[(452.42±191.72)ng/mL]in the healthy group,and the difference was statistically significant(t=13.13,P=0.000).The area under curve(AUC)value of ROC curve,sensitivity and specificity of CLEC38 protein were respectively 0.998,97.73%and 100.0%.Conclusion:CLEC3B is significantly decreased in sepsis group,which sensitivity and specificity are high.It can be used as a potentially biological diagnostic biomarker of sepsis.

Objective To investigate the initial dose and safety of intravenous infusion of sodium (s)-2-(dithiocarboxylato((2R,3R,4R,5R,6R)-2,3,4,5,6-pentahydroxyhexyl) amino)-4-(methylthio) butanoate (GMDTC) for the displacement of cadmium. Methodsi) Efficacy test. The New Zealand male rabbits were randomly divided into model group, calcium disodium edetate (EDTA) group and GMDTC low-, medium- and high-dose groups after cadmium poisoning using 2.5 cadmium chloride dihydrate. Rabbits in EDTA group were intravenously injected with EDTA dipotassium at a dose of 93.5 mg/kg body weight, rabbits in the three doses groups were intravenously injected of GMDTC at doses of 12.0, 36.0, and 108.0 mg/kg body weight, respectively. The rabbits in the control group (separate set) and model group were intravenously injected with equal volumes of 0.9% sodium chloride solution, administered for five consecutive days per week for 1, 2, and 4 weeks. ii) Toxicity test. Specific pathogen free SD rats were randomly divided into solvent control group and low-, medium- and high-dose groups. In the acute toxicity test, the rats in the three-dose groups were intravenously injected of GMDTC at doses of 200.0, 800.0 and 3 000.0 mg/kg body weight, respectively. In the long-term toxicity test, the rats in the three-dose groups were intravenously injected GMDTC at doses of 100.0, 500.0 and 2 000.0 mg/kg body weight, respectively, once a day for four consecutive weeks, with a recovery period of four weeks. The rats in the solvent control group were given an equal volume 0.9% sodium chloride solution intravenously at the same time. The maximum tolerated dose (MTD) and no observable adverse effect level (NOAEL) were detected. Resultsi) In the one week treatment experiment, the 24 hours urinary cadmium levels of rabbits in the three doses groups were higher than those in the model group at the same time point (all P<0.05). In the two weeks treatment experiment, the 24 hours urinary cadmium levels of rabbits in medium-dose and high-dose groups at the three time points were higher than those in the model group at the same time point (all P<0.05). In the four weeks treatment experiment, the 24 hours urinary cadmium level on the 19th day of rabbits in the low-dose group was higher than that in the model group at the same time point (P<0.05), and the 24 hours urinary cadmium levels of rabbits in medium- and high-dose groups at the five time points were higher than those in the model group at the same time point (all P<0.05), except for the rabbits of fifth day of the medium-dose group. The kidney cadmium levels of rabbits in the low-dose group after four week of treatment and in the medium- and high-dose groups after one, two, and four weeks of treatment decreased compared with the model group (all P<0.05). No obvious adverse effects were observed during the treatment. ii) The MTD of GMDTC in rats administered intravenously in a single dose was 3 000.0 mg/kg body weight. During the period of intravenous infuseion with GMDTC for four consecutive weeks, the blood drug level reached the peak at the end of the first and last administrations (eight min), and no clinical adverse reactions were observed during this period of time, nor was there any apparent accumulation. The NOAEL for intravenous infusion of GMDTC for four consecutive weeks in rats was 500.0 mg/kg body weight. Conclusion The initial dose of the GMDTC injection in the cadmium poisoning rabbit was 36.0 mg/kg body weight, and the recommended initial dose for human is 480.0 mg/person. Intravenous infusion of GMDTC is characterized by rapid absorption, rapid elimination, and no accumulation.

Objective:To screen key differentially expressed genes(DEGs)in dead mice with sepsis by spleen high-through-put sequencing combined with bioinformatics.Methods:①A mouse sepsis model was set up by intraperitoneal injection of lipopolysac-charide(LPS),a 7-day survival curve of mice was drawn,and the modeling doses of survival group and death group were screened out.②Expressions of TNF-α,IL-1β,IL-6 and IL-10 in peripheral blood of mice in control group,survival group and death group were verified by ELISA.③High-throughput sequencing was conducted on spleens of survival group and death group,and the key genes were screened by bioinformatics analysis of DEGs.④Expressions of key genes and proteins were detected by RT-PCR and Western blot.Results:①LPS dosage in survival group was 15 mg/kg(with a mortality of 30%),and LPS dosage in death group was 30 mg/kg(with a mortality of 80%).②Expression levels of IL-6,TNF-α and IL-1β in sepsis mice were significantly higher than those of control group,while expression level of IL-10 was decreased(P<0.05).Comparison of sepsis model groups showed that levels of pro-inflammatory factors in death group were higher than those in survival group,while level of IL-10 was lower than that in survival group(P<0.05).③A total of 2999 DEGs in survival group and death group were screened out by bioinformatics,among which 1185 genes were up-regulated and 1814 genes were down-regulated.Top 5 DEGs enrichment pathways were screened out:"hematopoietic cell lineage""primary immunodeficiency""African trypanosomiasis""leishmaniasis"and"B-cell receptor signaling pathway".Ifit1,Ifit3 and Mx1 were three key genes that were screened out.④Compared with survival group,expressions of genes and proteins of Ifit1,Ifit3 and Mx1 were down-regulated in spleen tissues of the death group(P<0.05).Conclusion:By high-throughput sequencing and bioinformatics,Ifit1,Ifit3 and Mx1 are screened out as key genes related to the death outcome of sepsis,which probably influence the outcome of sepsis through the immune mechanism related to virus infection.

Background/Aims: Colorectal cancer (CRC) is a common malignant tumor, and circular RNAs (circRNAs) are abnormally expressed in CRC. However, the function and underlying mechanism of circRNA pinin (circ-PNN; hsa_circ_0101802) in CRC remain unclear. Methods: Exosomes were isolated from the plasma of CRC patients and identified by transmission electron microscopy and Western blotting. The RNA expression levels of circ-PNN, miR-1225-5p, and fibroblast growth factor 13 (FGF13) were measured by quantitative real-time polymerase chain reaction. Cell proliferation was detected by Cell Counting K-8, colony formation, and 5-ethynyl-2’-deoxyuridine assays. Cell apoptosis was assessed by flow cytometry. The expression of apoptosis and metastasis-related proteins was evaluated by Western blotting. The associations among circ-PNN, miR-1225-5p, and FGF13 were confirmed by dual-luciferase report assay and RNA immunoprecipitation assay. A xenograft model was used to verify the function of circ-PNN in tumor formation in vivo. Results: circ-PNN expression was upregulated in plasmic exosomes derived from CRC patients. The expression of circ-PNN and FGF13 was upregulated, while miR-1225-5p expression was downregulated in CRC cells incubated with plasmic exosomes derived from CRC patients.Tumor-derived exosomes promoted the proliferation, migration, and invasion but inhibited apoptosis of CRC cells. Moreover, the addition of tumor-derived exosomes partly reversed the inhibitory effect of circ-PNN knockdown on CRC tumor progression in vitro and in vivo. Thus, circ-PNN acts as a sponge for miR-1225-5p to regulate FGF13 expression. Conclusions Tumor-derived exosomal circ-PNN promoted CRC progression through the regulation of the miR-1225-5p/FGF13 pathway, providing a potential therapeutic target for CRC.

OBJECTIVE: To assess the practical and health economical values of non-invasive prenatal test (NIPT) in Changsha Municipal Public Welfare Program. METHODS: A retrospective analysis was carried out on 149 165 women undergoing NIPT test from April 9, 2018 to December 31, 2019. For pregnant women with high risks, invasive prenatal diagnosis and follow-up of pregnancy outcome were conducted. The cost-benefit of NIPT for Down syndrome was analyzed. RESULTS: NIPT was carried out for 149 165 pregnant women and succeeded in 148 749 cases (99.72%), for which outcome were available in 148 538 (99.86%). 90% of pregnant women from the region accepted the screening with NIPT. 415 (0.27%) were diagnosed as high risk. Among these, 381 (91.81%) accepted amniocentesis, which led to the diagnosis of 212 cases of trisomy 21 (PPV=85.14%), 41 cases with trisomy 18 (PPV=48.81%) and 10 cases with trisomy 13 (PPV=20.83%). The sensitivity and specificity of NIPT for trisomy 21, trisomy 18 and trisomy 13 were (97.70%, 99.98%), (97.62%, 9.97%) and (100%, 99.97%), respectively. In addition, 213 and 30 cases were diagnosed with sex chromosomal aneuploidies (PPV=46.2%) and other autosomal anomalies (PPV=16.57%), respectively. For Down syndrome screening, the cost and benefit of the project was 120.79 million yuan and 1,056.95 million yuan, respectively. The cost-benefit ratio was 1: 8.75, and safety index was 0.0035. CONCLUSION NIPT is a highly accurate screening test for trisomy 21, which was followed by trisomy 18 and sex chromosomal aneuploidies, while it was less accurate for other autosomal aneuploidies. The application of NIPT screening has a high health economical value.
