Bluetongue virus is an arbovirus that seriously harms ruminants such as sheep,this study aims to investigate the molecular mechanism of bluetongue virus infection and host cell interferon antiviral immune response.The study was conducted to characterize the mRNA expression of inter-feron pathway genes by real-time fluorescence quantitative PCR,as well as Western blot analysis of MDA5,TRAF3,RIG-Ⅰ,and TBK1 protein expression in BHK-21 cells induced by BTV with a multiplicity of infections(MOI)of 1 for 18,24,and 36 h.The results showed that the most pro-nounced changes in the expression of interferon signaling pathway genes were observed at 24 h of induction,the gene mRNA expression levels of the IFN-α,IFN-β,RIG-Ⅰ,TBK1,MDA5,VISA,and TRAF3 genes were upregulated.However,the mRNA expression levels of IKKε and TRAF6 genes were downregulated.At the protein level,MDA5 and TBK1 proteins were upregulated while RIG-1 and TRAF3 proteins were downregulated,which showed that BTV infection induces a typeⅠ interferon immune response in BHK-21 cells.This study lays the foundation for further exploring the antiviral immunity mechanism of IFN-Ⅰ signaling pathway regulatory genes in host cells infected with BTV infection.

Objective:To explore the optimal regimen of standardized mite allergen immunotherapy for airway allergic diseases in children, and to observe the clinical efficacy, safety and compliance.Method:Use a retrospective real-world study, clinical data from 156 children aged 5-16 years who received subcutaneous immunotherapy (SCIT) with double mite allergen preparation in the pediatrics department of the Third Affiliated Hospital of Sun Yat sen University from June 2019 to September 2020 were selected for allergic rhinitis (AR) and/or allergic asthma (bronchial asthma, BA), including gender, age, total VAS(visual analogue scale) score and CSMS(combined symptom and medication scores) score at different time points (before treatment, 4-6 months, 1 year, and 2 years after initiation of desensitization), peripheral blood eosinophil counts (EOS), serum total IgE (tIgE), specific IgE (tIgE), and serum IgE (tIgE), specific IgE (sIgE), tIgG4, and incidence of local and systemic adverse reactions. All patients had a consistent regimen during the initial treatment phase (dose-escalation phase), which was performed as directed. Among them, 81 cases (observation group) continued to continue subcutaneous injection of 1 ml of vial No. 3 every 4-6 weeks during the dose maintenance phase, while 75 cases (control group) followed the old traditional regimen during the maintenance phase (i.e., change to a new vial to halve the amount of vial No. 3 by 0.5 ml, and then 0.75 ml after 1-2 weeks, and 1 ml in a further interval of 1-2 weeks). The clinical efficacy, safety and adherence to the treatment were compared between the two groups.Results:A total of 81 cases of 156 children were included in the observation group, of which 58 children with AR, 15 children with BA, and 8 children with AR combined with BA; 75 cases were included in the conventional control group, of which 52 children with AR, 16 children with BA, and 7 children with AR combined with BA. In terms of safety, the difference in the incidence of local and systemic adverse reactions between the two groups was not statistically significant ( χ2=1.541 for local adverse reactions in the control group, χ2=0.718 for the observation group; χ2=0.483 for systemic adverse reactions in the control group, χ2=0.179 for the observation group, P value >0.05 for all of these), and there were no grade Ⅱ or higher systemic adverse reactions in any of them. In the control group, there were 15 cases of dropout at 2 years of follow-up, with a dropout rate of 20.0%; in the observation group, there were 7 cases of dropout at 2 years of follow-up, with a dropout rate of 8.6%, and there was a statistically significant difference in the dropout rates of the patients in the two groups ( χ2=4.147, P<0.05). Comparison of serological indexes and efficacy (compared with baseline at 3 different time points after treatment, i.e., 4-6 months, 1 year and 2 years after treatment), CSMS scores of the observation group and the conventional control group at 4-6 months, 1 year and 2 years after treatment were significantly decreased compared with the baseline status ( t-values of the conventional group were 13.783, 20.086 and 20.384, respectively, all P-values <0.001, and t-values of the observation group were 15.480, 27.087, 28.938, all P-values <0.001), and VAS scores also decreased significantly from baseline status in both groups at 4-6 months, 1 year, and 2 years of treatment ( t-values of 14.008, 17.963, and 27.512 in the conventional control group, respectively, with all P-values <0.001, and t-values of 9.436, 13.184, and 22.377 in the observation group, respectively; all P-values <0.001). Intergroup comparisons showed no statistically significant differences in CSMS at baseline status, 4-6 months, 1 year and 2 years ( t-values 0.621, 0.473, 1.825, and 0.342, respectively, and P-values 0.536, 0.637, 0.070, and 0.733, respectively), and VAS was no statistically significant difference in comparison between groups at different time points ( t-values of 1.663, 0.095, 0.305, 0.951, P-values of 0.099, 0.925, 0.761, 0.343, respectively); suggesting that the treatment regimens of the observation group and the conventional control group were clinically effective, and that the two regimens were comparable in terms of efficacy. The peripheral blood eosinophil counts of the observation group and the conventional control group decreased significantly from the baseline status at 4-6 months, 1 year and 2 years of treatment ( t-values of the conventional group were 3.453, 5.469, 6.273, P-values <0.05, and the t-values of the observation group were 2.900, 4.575, 5.988, P-values <0.05, respectively). 4-6 months, 1 year and 2 years compared with the baseline status tIgE showed a trend of increasing and then decreasing ( t-value in the conventional group was -5.328, -4.254, -0.690, P-value was 0.000, 0.000, 0.492, respectively, and t-value in the observation group was -6.087, -5.087, -0.324, P-value was 0.000, 0.000, 0.745, respectively). However, the results of intergroup comparisons showed no statistically significant differences in serological indices and efficacy between the two groups in terms of peripheral blood eosinophil counts at baseline status, 4-6 months, 1 year and 2 years ( t-values of 0.723, 1.553, 0.766, and 0.234, respectively; P-values of 0.471, 0.122, 0.445, and 0.815, respectively), tIgE ( t-values of 0.170, -0.166, -0.449, 0.839, P-values 0.865, 0.868, 0.654, 0.403, respectively), tIgG4 ( t-values 1.507, 1.467, -0.337, 0.804, P-values 0.134, 0.145, 0.737, 0.422, respectively). Conclusion:Both immunotherapy regimens for airway allergic diseases with double mite allergen subcutaneous immunotherapy have significant clinical efficacy, low incidence of adverse reactions, and the observation group has better patient compliance than the control group.

ObjectiveTo investigate the mental health of pediatricians in Guangzhou and its influencing factors， and to provide countermeasures for improving the mental health of pediatricians. MethodsA stratified random sampling method was used to randomly select 400 pediatricians in 11 districts of Guangzhou， and they were surveyed using the Symptom Check List（SCL-90） and the Job Stressor Scale. ResultsThe top three job stressors scored by pediatricians in Guangzhou were external environment （3.23±0.59）， workload （3.19±0.56）， and organizational management （2.74±0.55）. All factor scores were higher than those of the clinician group except for career interest， and the difference was statistically significant （P<0.01）. The number of pediatricians with mental health problems was 109， accounting for 27.25%. All factor scores were higher than the physician norm except for anxiety and paranoia. The correlations between each factor of work stressors and each factor of SCL-90 were positive and statistically significant （P<0.05）， except for two pairs of factors， workload and terror as well as external environment and terror. The results of univariate analysis showed statistically significant differences in the mental health scores of pediatricians with different health status， years of work experience， job satisfaction， job stress， and career prospects （P<0.05）. The results of multiple linear regression showed that health status， years of work experience， professional interest， interpersonal relationship， and doctor-patient relationship were influential factors in the mental health of pediatricians （P<0.05）. ConclusionThe mental health of pediatricians in Guangzhou is unsatisfactory， and the factors affecting them are mainly external objective factors such as workload and organizational management.

This study aimed to systematically evaluate the efficacy and safety of different Chinese patent medicines in the treatment of idiopathic membranous nephropathy. The relevant randomized controlled trial(RCT) was retrieved from PubMed, EMbase, Cochrane Library, CNKI, SinoMed, Wanfang, and VIP with the time interval from database inception to December 2022. The Cochrane risk of bias assessment tool was employed to evaluate the quality of the included RCT, and Stata 15.0 and GEMTC to perform the Bayesian network Meta-analysis. Finally, 51 RCTs were included, involving 9 Chinese patent medicines and 3 591 patients. The results of network Meta-analysis showed that in terms of the total effective rate and the increase in plasma albumin, the top three interventions were Zhengqing Fengtongning Sustained Release Tablets + conventional western medicine, Bailing Capsules + conventional western medicine, and Tripterygium Glycosides Tablets + conventional western medicine. In terms of reducing 24-hour urine total protein, the top three interventions were Zhengqing Fengtongning Sustained Release Tablets + conventional western medicine, Shenfukang Capsules +conventional western medicine, and Huangkui Capsules + conventional western medicine. In terms of reducing serum creatinine, the top three interventions were Shenfukang Capsules + conventional western medicine, Bailing Capsules + conventional western medicine, and Zhengqing Fengtongning Sustained Release Tablets + conventional western medicine. In terms of safety, Chinese patent medicines combined with conventional western medicine had fewer adverse reactions than the control group. The results suggest that Chinese patent medicines combined with conventional western medicine can improve the therapeutic effect on idiopathic membranous nephropathy, and differentiated medications can be adopted according to the specific symptoms of patients in clinical treatment. Further validation needs to be carried out in the future with multi-center, large-sample, and high-quality RCT.

OBJECTIVE: To observe the correlation between early fluid resuscitation and prognosis in patients with severe acute pancreatitis (SAP). METHODS: SAP patients admitted to the department of critical care medicine of the People's Hospital of Chuxiong Yi Autonomous Prefecture of Yunnan Province from June 2018 to December 2020 were enrolled and analyzed retrospectively. All patients were given the routine treatment according to their condition and relevant diagnostic According to their different prognosis, enrolled patients were divided into death group and survival group. The differences in gender, age, acute physiology and chronic health evaluation II (APACHE II) and Ranson score on admission between the two groups were analyzed. Taking 24 hours as an observation day, the fluid inflow, outflow, and net balance at the first, second, and third 24 hours after admission were recorded, and the ratio of the fluid inflow at the first 24 hours to the total fluid inflow in 72 hours (FV_{24 h-1 st}) was calculated as a study index. Using 33% as the standard, compare the proportion of patients in the two groups who achieved FV_{24 h-1 st} < 33%. The differences of various indicators between the two groups were compared, and the effect of early fluid balance on the prognosis of SAP patients was analyzed. RESULTS: Eighty-nine patients were included in the study (41 in the death group, 48 in the survival group). There were no statistically significant differences on age (years old: 57.6±15.2 vs. 49.5±15.2), gender (male: 61.0% vs. 54.2%), APACHE II score (18.0±2.4 vs. 17.3±2.3), and Ranson score (6.3±1.4 vs. 5.9±1.2) between the death group and the survival group at the time of admission on the intensive care unit (ICU) (all P > 0.05). The fluid intake of the death group in the first 24 hours, the second 24 hours and the third 24 hours after admission to ICU was significantly higher than that of the survival group, and the difference was statistically significant (mL: 4 138±832 vs. 3 535±1 058, 3 883±729 vs. 3 324±516, 3 786±490 vs. 3 212±609, all P < 0.05), and the fluid inflow in the death group at the first 24 hours was greater than 4 100 mL. After treatment, the fluid outflow of the death group at the three 24-hour periods after admission on the ICU was an increasing trend, but it was still significantly less than that of the survival group at the three 24-hour periods (mL: 1 242±465 vs. 1 795±819, 1 536±579 vs. 2 080±524, 1 610±585 vs. 2 932±752, all P < 0.01). Due to the fact that the total fluid inflow and total fluid outflow in the three 24-hour periods in the death group were more than those in the survival group, the net fluid balances in the three 24-hour periods in the death group were still significantly more than those in the survival group finally (mL: 2 896±782 vs. 1 740±725, 2 347±459 vs. 1 243±795, 2 176±807 vs. 338±289, all P < 0.01). There was no difference in FV_{24 h-1 st} between the death group and survival group [FV_{24 h-1 st} > 33%: 56.1% (23/41) vs. 54.2% (26/48), P > 0.05]. CONCLUSIONS Fluid resuscitation is an important method for early treatment of SAP, but it also has many adverse reactions. Fluid resuscitation indexes such as fluid inflow, outflow, net balance, and FV_{24 h-1 st} within 24 to 72 hours after admission are related to the prognosis of patients with SAP, and can be used as indicators to evaluate the prognosis of SAP. The optimized fluid resuscitation strategy can improve the prognosis of patients with SAP.

Five new terpenoids, including two vibsane-type diterpenoids (1, 2) and three iridoid allosides (3-5), together with eight known ones, were isolated from the leaves and twigs of Viburnum odoratissimum var.sessiliflorum. Their planar structures and relative configurations were determined by spectroscopic methods, especially 2D NMR techniques. The sugar moieties of the iridoids were confirmed as β-D-allose by GC analysis after acid hydrolysis and acetylation. The absolute configurations of neovibsanin Q (1) and dehydrovibsanol B (2) were determined by quantum chemical calculation of their theoretical electronic circular dichroism (ECD) spectra and Rh₂(OCOCF₃)₄-induced ECD analysis. The anti-inflammatory activities of compounds 1, 3, 4, and 5 were evaluated using an LPS-induced RAW264.7 cell model. Compounds 3suppressed the release of NO in a dose-dependent manner, with an IC₅₀ value of 55.64 μmol·L^-1. The cytotoxicities of compounds 1-5 on HCT-116 cells were assessed and the results showed that compounds 2 and 3 exhibited moderate inhibitory activities with IC₅₀ values of 13.8 and 12.3 μmol·L^-1, respectively.

ObjectiveTo investigate the effect of microemulsion on the distribution of index components in different phases of Zexietang extract based on high performance liquid chromatography（HPLC） and phase separation process. MethodParticle size meter and transmission electron microscope were used to characterize the colloidal particles in blank microemulsion， aqueous extract of Zexietang and microemulsion extract of Zexietang. The phase separation process was established by high-speed centrifugation and dialysis， and based on this process， the aqueous extract and microemulsion extract of Zexietang were separated into the true solution phase， the colloidal phase and the precipitation phase， respectively. The contents of six components， including atractylenolide Ⅲ， atractylenolide Ⅱ， 23-acetyl alisol C， alisol A， alisol B and alisol B 23-acetate， were determined by HPLC with the mobile phase of water（A）-acetonitrile（B） for gradient elution（0-5 min， 40%-43%B； 5-20 min， 43%-45%B； 20-45 min. 45%-60%B； 45-75 min， 60%-80%B）. The solubility of the index components in water and microemulsion was determined by saturation solubility method. ResultThe colloidal particles in the aqueous extract， microemulsion extract and blank microemulsion were all spherical， and the particle size， polydispersity index（PDI） and Zeta potential of the colloidal particles were in the order of aqueous extract >microemulsion extract >blank microemulsion. The results of phase separation showed that the colloidal phase and the true solution phase could be completely separated by dialysis for 2.5 h， and the phase separation process was tested to be stable and feasible. Compared with the aqueous extract of Zexietang， the use of microemulsion as an extraction solvent could increase the contents of atractylenolide Ⅲ， 23-acetyl alisol C， atractylenolide Ⅱ ， alisol A， alisol B and alisol B 23-acetate by 3.75， 6.82， 35.47， 10.66， 35.41， 27.75-fold， and could increase the extraction efficiencies of the latter five constituents by 2.03， 1.15， 1.70， 6.43， 5.53 times. The solubility test showed that the microemulsion could significantly improve the solubility of atractylenolide Ⅱ， alisol A， alisol B and alisol B 23-acetate， but it had less effect on the solubility of atractylenolide Ⅲ and 23-acetyl alisol C. ConclusionMicroemulsion can improve the extraction efficiency and increase the distribution of the index components in the colloidal phase state of Zexietang to different degrees， providing a reference for the feasibility of microemulsion as an extraction solvent for traditional Chinese medicine.
