Objective:To analyze the clinical characteristics and cytokines expression characteristics in infants with mild and severe respiratory syncytial virus (RSV) infection.Methods:From May 2023 to December 2023, plasma samples and clinical information were collected from 16 infants with RSV infection and 14 control infants. Cytek Aurora flow cytometry (Cytek, America) and Enzyme linked immunosorbent assay (ELISA) were used to detect the expression levels of 25 cytokines after mild and severe RSV infection.Results:Cough and nasal obstruction were the main clinical manifestations in infants with mild RSV infection, accompanied by polypnea, wheezing and other symptoms. The main symptoms of severe RSV infection were cough and rales, accompanied by fever and polypnea. In comparison with the control group, the expression levels of IL-2, IL-4, IL-5, IL-6, IL-9, IL-13, IL-22, TNF-α, IFN-α, IFN-β, MIP-1β, I-TAC, ENA-78, GROα, Eotaxin, and MCP-1 in the RSV infection group all exhibited an upregulation trend. Both IP-10 and MIP-3α demonstrated a downward trend in the RSV infection group; however, there was no statistically significant difference ( P>0.05). The levels of IL-10, IFN-γ, MIP-1α, and IL-8 in the RSV infection group were significantly higher than those in the control group, whereas the levels of MIG, TARC, and RANTES in the RSV infection group were significantly lower than those in the control group ( P<0.05). The levels of IL-2, IL-4, IL-5, IL-6, IL-9, IL-10, IL-13, IL-22, IFN-β, IFN-γ, TNF-α, IL-8, I-TAC, MIP-1β, Eotaxin, and MCP-1 in the mild RSV infection group were significantly higher than those in the severe RSV infection group ( P>0.05). Among these, the levels of MIG, RANTES, TARC, MIP-3α, and ENA-78 in the mild infection group were all lower than those in the severe infection group. The expressions of ENA-78 and MIP-1α in the severe infection group were significantly higher than those in the mild infection group and also higher than those in the control group. There was no significant difference in IP-10 and GROα between the mild and severe RSV infection groups ( P>0.05). Conclusions:The differences in clinical features and cytokines between infants with mild and severe RSV infection provide important data support for the prevention and treatment of RSV infection in infants.

Objective To establish a brucellosis monitoring and testing technique applicable for the rapid field screening of natural epidemic diseases.Methods A rapid testing technique for Brucella was developed based on a double-antibody sandwich testing model using gradient-variant quantum dots as fluorescent tracers.The sensitivity,linearity,precision,and specificity of the technique were evaluated using suspensions of standard Brucella strains.Methodological comparisons across different sample types were conducted to assess the consistency of the test results.Results The gradient-variant quantum dots detection method was evaluated with standard Brucella strains,exhibiting a sensitivity of 1×103 CFU/mL and a linear correlation coefficient(r)of 0.994(95%CI,0.933-1.055).The maximum coefficient of variation was 12.94%in repeated tests,showing good specificity.A comparative assessment of 305 clinical samples was conducted using the Brucella gradient-variant quantum dots detection method,the Rose Bengal plate agglutination test(RBT),and the serum agglutination test(SAT),yielding a Kappa value of 0.95,indicating almost perfect agreement.Additionally,a comparative assessment of 110 environmental samples collected on-site was conducted using the Brucella gradient-variant quantum dots detection method and quantitative real-time PCR(qPCR).The Kappa values for aerosol collection fluid,surface wipes,and wool samples were all above 0.83,demonstrating near-perfect agreement.For fecal and soil samples,the Kappa values were above 0.62,indicating substantial agreement.Conclusion The Brucella detection method based on gradient-variant quantum dots technology is simple and can be conducted rapidly.The detection method demonstrates high sensitivity,linearity,precision,and specificity.It shows consistent performance in clinical sample testing.It is well-suited for field rapid screening of natural epidemic diseases in field settings and shows good application prospects in the monitoring,prevention,and rapid detection of zoonotic diseases.

Objective To systematically analyze the current status of judicial adjudication in medical-injury cases involving shortened survival,identify core issues in forensic identification and adjudication,and propose targeted improvements.Methods We searched China Judgments Online for 88 effective judgments and conducted quantitative and qualitative analyses across four dimensions:patient baseline characteristics,forensic identification procedures,trial process,and adjudicative outcomes.Results The judicial support rate for shortened survival claims was 25％.Marked practice divergences were observed:only 28.4％of cases explicitly cited authoritative survival statistics as the scientific basis for opinions;four compensation-calculation approaches were identified with inconsistent standards;the second-instance reversal rate reached 20％.Conclusion It is necessary to develop a unified technical specification for forensic identification of shortened survival,establish scientifically grounded compensation-calculation models,and strengthen multidisciplinary collaboration mechanisms to enhance the credibility of adjudication.

Objective To explore the protective effect of wogonin on retinal ganglion cells(RGC)in mice with glau-coma and its related mechanism.Methods Ten(10 eyes)C57BL/6J mice were included in the control group,and 40(40 eyes)DBA/2J mice were selected to prepare glaucoma models,which were divided into the model group,experiment 1,2 and 3 groups,with 10 mice per group.Mice in the control and model groups were given normal saline intragastrically,and mice in the experiment 1,2 and 3 groups were intragastrically given 50,100 and 150 mg·kg-1 wogonin,respectively.The right eyes were selected as experimental eyes.The intraocular pressure(IOP)of mice was compared among the five groups before and after 2,4 and 8 weeks of intragastric administration.The RGC number and retinal thickness of mice in each group were compared after hematoxylin-eosin staining.The levels of superoxide dismutase(SOD),glutathione peroxidase(GSH-Px)and nitric oxide synthase(NOS)in the retinal tissues of mice were detected by colorimetry.The levels of inter-leukin(IL)-6,IL-1 β and tumor necrosis factor-α(TNF-α)in the retinal tissues of mice were detected by enzyme-linked im-munosorbent assay.The expression levels of nucleotide oligomerization domain-like receptor family 3(NLRP3),Caspase-1 and apoptosis-associated speck-like protein(ASC)in the retinal tissues of mice were detected by Western blot.Results Compared with the control group,IOP in the model group and the experiment 1,2 and 3 groups increased(all P＜0.05)before intragastric administration.After 2,4 and 8 weeks of intragastric administration,IOP in the model group and the ex-periment 1,2 and 3 groups increased compared with the control group(all P＜0.05);IOP in the experiment 1,2 and 3 groups decreased compared with the model group(all P＜0.05);IOP in the experiment 2 and 3 groups decreased compared with the experiment 1 group(both P＜0.05);IOP in the experiment 3 group decreased compared with the experiment 2 group(P＜0.05).Compared with the control group,the number of RGC,retinal thickness,SOD and GSH-Px levels in the model group and the experiment 1,2 and 3 groups decreased,while the expression levels of NOS,IL-6,IL-1 β,TNF-α,and NLRP3,Caspase-1 and ASC proteins increased,and the differences were statistically significant(all P＜0.05).Compared with the model group,the number of RGC,retinal thickness,SOD and GSH-Px levels in the experiment 1,2 and 3 groups increased,while the expression levels of NOS,IL-6,IL-1β,TNF-α,and NLRP3,Caspase-1 and ASC proteins decreased,and the differences were statistically significant(all P＜0.05).Compared with the experiment 1 group,the number of RGC,retinal thickness,SOD and GSH-Px levels in the experiment 2 and 3 groups increased,while the expression levels of NOS,IL-6,IL-1 β,TNF-α,and NLRP3,Caspase-1 and ASC proteins decreased(all P＜0.05);compared with the experi-ment 2 group,the number of RGC,retinal thickness,SOD and GSH-Px levels in the experiment 3 group increased,while the expression levels of NOS,IL-6,IL-1β,TNF-α,and NLRP3,Caspase-1 and ASC proteins decreased(all P＜0.05).Conclusion Wogonin can improve the retinal thickness of mice with glaucoma and alleviate retinal oxidative damage and inflammatory reaction,which may be related to inhibiting the activation of NLRP3 inflammasomes.

Objective:To explore the clinical characteristics and risk factors of sarcopenia in elderly patients with chronic kidney disease (CKD) stage 3-4.Methods:It was a single-center, retrospective observational study. CKD stage 3-4 patients aged ≥60 years old from March 2019 to March 2022 in the Geriatrics Department of the First Affiliated Hospital of Zhengzhou University were enrolled in the study. General data of the patients were collected, and laboratory indicators, muscle strength, physical function and appendicular muscle mass index (ASMI) were measured. According to the diagnostic criteria of sarcopenia, the patients were divided into no sarcopenia CKD group and sarcopenia CKD group. Baseline data between these two groups were compared. Logistic regression analysis was used to analyze the related factors of sarcopenia in elderly CKD stage 3-4 patients.Results:A total of 162 CKD stage 3-4 patients were enrolled in this study, with 89 males (54.9%) and a median age of 75 (69, 82) years. Sarcopenia was diagnosed in 40 cases, and the prevalence was 24.7% (95% CI 18.1%-31.3%). Compared with no sarcopenia CKD group, age, proportion of dementia, cystatin C, urea nitrogen, C-reactive protein (CRP) and ratio of urine protein to creatinine were higher (all P<0.05), while body mass index (BMI), hemoglobin, carbon dioxide combining power, estimated glomerular filtration rate (eGFR), serum albumin and the proportion of regular exercise and using α-ketones were lower in sarcopenia CKD group (all P<0.05). Meanwhile, grip strength, walking speed, short physical performance battery score and ASMI were lower in sarcopenia CKD group (all P<0.05). Multivariable logistic regression analysis results showed that low eGFR ( OR=0.824, 95% CI 0.687-0.987, P=0.036), low BMI ( OR=0.463, 95% CI 0.304-0.704, P<0.001), low serum albumin ( OR=0.459, 95% CI 0.263-0.802, P=0.006) and high CRP ( OR=2.754, 95% CI 1.708-4.439, P<0.001) were the independent related factors of sarcopenia in elderly CKD patients. Conclusions:The prevalence of sarcopenia in elderly CKD stage 3-4 patients is high. Low eGFR, low BMI, low serum albumin and high CRP are the independent risk factors for sarcopenia in elderly CKD stage 3-4 patients.

Objective:To evaluate the effect of five external treatment methods of traditional Chinese medicine on the pain of patients with lumbar disc herniation (LDH) through a network Meta-analysis.Methods:The published article on the effect of external treatment methods of Traditional Chinese Medicine in patients with LDH was retrieved by computer in China National Knowledge Infrastructure, WanFang Database, VIP, China Biomedical Database, PubMed, Cochrane Library and Web of Science. The retrieval time limit was from the establishment of the database to May 31, 2022. Two researchers independently screened the article according to the inclusion and exclusion criteria, extracted the information and evaluated the quality. Review Manger 5.4 software was used to draw the bias risk map and Stata SE 16.0 software was used to conduct the network Meta-analysis.Results:A total of 1 133 patients were included in 12 articles, and there were five kinds of external treatment methods of Traditional Chinese Medicine. The results of network Meta-analysis showed that except for acupoint application, scraping, Traditional Chinese Medicine iontophoresis, Traditional Chinese Medicine scalding, auricular point sticking had statistically significant differences in the effect of pain compared with conventional treatment and nursing ( P<0.05). There were no statistically significant differences between the five external treatment methods of Traditional Chinese Medicine ( P>0.05). The cumulative ranking plot showed that scraping was the best intervention method for pain in LDH patients, with a surface under the cumulative ranking ( SUCRA) value of 80.3%. Conclusions:Scraping is the best external treatment of traditional Chinese medicine to relieve the pain of LDH patients, but it still needs to be further demonstrated by a large number of high-quality randomized controlled trials.
