Allergen-specific immunotherapy（AIT） remains the only therapeutic approach with the potential to modify the natural course of allergic rhinitis（AR）. Nevertheless, considerable inter-individual variability exists in patients'responses to AIT. To facilitate more reliable assessment of treatment efficacy, the China Rhinopathy Research Cooperation Group（CRRCG） convened young and middle-aged nasal experts in China to formulate the present consensus. The recommended subjective outcome measures for AIT comprise symptom scores, medication scores, combined symptom and medication scores, quality-of-life assessments, evaluation of disease control, and assessment of comorbidities. Objective indicators may supplement these measures. Currently available objective approaches include skin prick testing, nasal provocation testing, and allergen exposure chambers. However, these methods remain constrained by practical limitations and are not yet appropriate for routine implementation in clinical efficacy evaluation. In addition, several biomarkers, including sIgE and the sIgE/tIgE ratio, sIgG4, serum IgE-blocking activity, IgA, cytokines and chemokines, as well as immune cell surface molecules and their functional activity, have been shown to have associations with AIT outcomes. While these biomarkers may complement subjective assessments, they are subject to significant limitations. Consequently, large-scale multicenter trials and real-world evidence are required to strengthen the evidence base. The present consensus underscores the necessity of integrating patients'subjective experiences with objective testing throughout the treatment process, thereby providing a more comprehensive and accurate framework for efficacy evaluation. Looking forward, future investigations should prioritize the incorporation of multi-omics data and artificial intelligence methodologies, which hold promise for overcoming current limitations in assessment strategies and for advancing both the standardization and personalization of AIT.

This study was performed to investigate the inhibitory effects of Xuebijing injection(XBJ)on lipopolysaccharide(LPS)-induced inflammatory signals on EA.hy926 vascular endothelial cells and the underlying mechanism,and to provide a theoretical basis for the treatment of sepsis with XBJ.WST-1 assay was used to detect the effects of XBJ on the cell viability;Western blot analysis was performed to detect the protein expression levels of IκBα,p-p65,p-ERK,p-JNK,p-p38,p-AMAD17 in cell lysates and the content of sTLR4 fragment in the concentrated culture supernatants.ADAM17 sheddase activity in cells was detected by using a commercial available kit.Data showed that all of the TLR4-mediated inflammatory signals were significantly inhibited by the treatment of XBJ(P＜0.01).ADAM17 phosphorylation and shedding activity were induced by XBJ treatment,simultaneously the sTLR4 contents in the culture media were increased.XBJ-induced shedding of TLR4 was suppressed by the preteatment of 10 μmol/L TAPI-1(an ADAM17 inhibitor).Taken together,XBJ can induce the shedding of TLR4 from cell membrane by up-regulating ADAM17 shedding activity,thereby inhibiting the activation of TLR4-mediated intracellular inflammatory signals in EA.hy926 cells.

Objective:To investigate the safety of early antiplatelet therapy for non-cardioembolic mild stroke patients with thrombocytopenia.Methods:Data of acute ischemic stroke patients with baseline National Institutes of Health Stroke Scale(NIHSS)score≤3 and a platelet count<100×109/L were obtained from a multicenter register.Those who required anticoagulation or had other contraindications to antiplatelet therapy were excluded.Short-term safety outcomes were in-hospital bleeding events,while the long-term safety outcome was a 1-year all-cause death.The short-term neurological outcomes were evaluated by modified Rankin scale(mRS)score at discharge.Results:A total of 1868 non-cardioembolic mild stroke patients with thrombocytopenia were enrolled.Multivariate regression analyses showed that mono-antiplatelet therapy significantly increased the proportion of mRS score of 0-1 at discharge(OR=1.657,95%CI:1.253-2.192,P<0.01)and did not increase the risk of intracranial hemorrhage(OR=2.359,95%CI:0.301-18.503,P>0.05),compared with those without antiplatelet therapy.However,dual-antiplatelet therapy did not bring more neurological benefits(OR=0.923,95%CI:0.690-1.234,P>0.05),but increased the risk of gastrointestinal bleeding(OR= 2.837,95%CI:1.311-6.136,P<0.01)compared with those with mono-antiplatelet therapy.For patients with platelet counts≤75×109/L and>90×109/L,antiplatelet therapy significantly improved neurological functional outcomes(both P<0.05).For those with platelet counts(>75-90)×109/L,antiplatelet therapy resulted in a significant improvement of 1-year survival(P<0.05).For patients even with concurrent coagulation abnormalities,mono-antiplatelet therapy did not increase the risk of various types of bleeding(all P>0.05)but improved neurological functional outcomes(all P<0.01).There was no significant difference in the occurrence of bleeding events,1-year all-cause mortality risk,and neurological functional outcomes between aspirin and clopidogrel(all P>0.05).Conclusions:For non-cardioembolic mild stroke patients with thrombocytopenia,antiplatelet therapy remains a reasonable choice.Mono-antiplatelet therapy has the same efficiency as dual-antiplatelet therapy in neurological outcome improvement with lower risk of gastrointestinal bleeding.

Objective : By observing the changes of interleukin-22 ( IL-22) ，signal transduction and transcriptional activator 3 (STAT3) ，fasting blood glucose ( FBG) and fasting insulin ( FINS) of rats under the circumstance of chronic intermittent hypoxia and reoxygenation，to explore the role of IL-22 / STAT3 pathway in insulin resistance in- duced by chronic intermittent hypoxia． Methods : 4 SD rats were randomly divided into control group (NC group) and intermittent hypoxia group ( CIH group) ，with 12 rats in each group．NC group was placed in normoxia environment for 12 weeks，while CIH group was first given intermittent hypoxia for 8 weeks and then resumed normoxia feeding until 12 weeks．FBG，FINS，IL-22 and p-STAT3 / STAT3 levels were measured at baseline，week 8 and week 12 in both groups，and insulin resistance index (HOMA-IR) was calculated．The differences between the two groups were compared. Results : ① There was no significant difference of the observation indexes between the two groups at baseline (P＞0. 05) ．At 8 weeks，the levels of FBG，FINS and HOMA-IR in CIH group were higher than those in NC group (P＜0. 05) ，and the levels of IL-22 were lower than those in NC group (P ＜0. 05) ．p-STAT3 / STAT3 showed a decreasing trend，but not statistically significant．At 4 weeks of reoxygenation，there were no significant differences in FBG，FINS，HOMA-IR and IL-22 levels between the two groups (P ＞0. 05 ) ．p-STAT3 / STAT3 in CIH group was significantly higher than that in NC group ( P ＜0. 05 ) . ② Spearman rank correlation analysis showed that HOMA-IR was negatively correlated with IL-22 and p-STAT3 / STAT3 ( all P ＜0. 05) ． Conclusion Chronic intermittent hypoxia can inhibit the expression of IL-22 / STAT3 signaling pathway，IL-22 / STAT3 signaling pathway may mediate insulin resistance induced by chronic intermittent hypoxia.

Objective:To observe the effect of shift work on the stability of the circadian clock and insulin sensitivity in non-overweight/obese individuals with normal blood glucose, and explore underlying connection.Methods:Female shift working nurses in the Department of Blood Transplantation and non-shift working nurses in the Health Management Center in the First Affiliated Hospital of Zhengzhou University were divided into shift worker group (SW group) and non-shift worker group (NSW group). Serum inflammatory factors [interleukin-6 (IL-6), tumor necrosis factor-α(TNF-α)], adipokines (adiponectin, leptin, chemerin, visfatin), and melatonin levels were measured using enzyme linked immunosorbent assay (ELISA). Realtime fluorescence quantitative PCR was performed to detect peripheral blood circadian clock genes circadian locomotor output cycles protein kaput(Clock) and brain and muscle ARNT-like protein 1(Bmal1). Cortisol and fasting insulin were measured by chemiluminescent microparticle immunoassay, and HbA 1C was measured by capillary electrophoresis. In addition, visceral fat area (VFA) was assessed with bioelectrical impedance analyzer, and mid-sleep time composite phase deviations (CPD) was calculated based on the International Physical Activity Short Questionnaire. Results:SW group had lower serum level of melatonin ( P=0.023) and higher cortisol ( P=0.001) than the NSW group, and altered mRNA expression of Clock and Bmal1 ( P=0.034, P=0.047). Fasting blood glucose and HbA 1C in the SW group, although in the normal range, had been higher than in the NSW group ( P=0.011, P=0.033). Although body mass index was normal in SW group, VFA had been higher than that of the NSW group ( P=0.010). And homeostasis model assessment for insulin resistance (HOMA-IR), IL-6, TNF-α, leptin, chemerin, and visfatin were significantly higher in the SW group than NSW group ( P=0.033, P=0.012, P=0.001, P=0.011, P=0.021, P=0.007). In addition, adjusting for body mass index and activity factors revealed a significant positive correlation between CPD and VFA ( r=0.434, P=0.049), inflammatory factors IL-6 ( r=0.514, P=0.017) and TNF-α ( r=0.700, P<0.001) and pro-inflammatory adipokines leptin ( r=0.473, P=0.030), chemerin ( r=0.439, P=0.047), visfatin ( r=0.521, P=0.015). Conclusion:Shift work can affect circadian clock, with increased visceral adiposity, pro-inflammatory adipokines, inflammatory factors and decreased insulin sensitivity in women without overweight/obese.

Objective:To observe the effects of continuous light exposure on skeletal muscle fiber type transformation and lipid metabolism, and to explore its internal relationship.Methods:Mice were randomly divided into normal light group and 24-hour continuous light group by random number table. The serum and skeletal muscle lipid content and urine 6-sulfatoxymelatonin(6-SML)level were detected by ELISA. The expression of circadian clock and lipid metabolism related genes mRNA were observed by realtime PCR. The muscle fiber type and lipid deposition were evaluated by tissue immunofluorescence as well as oil red O staining.Results:Compared with the normal light group, the level of 6-SML in urine at night decreased( P<0.05), and the expression level and rhythm of brain and muscle ARNT-like protein 1(Bmal1), circadian locomotor output cycles protein kaput(Clock), and period 2(Per2)mRNA in the skeletal muscle changed in continuous light group. In addition, the body weight, blood lipid, free fatty acid, and triglyceride contents of skeletal muscle in continuous light group increased significantly( P<0.05 or P<0.01), the expression of carnitine palmitoyltransferase 1b (Cpt1b)mRNA, the key enzyme of fatty acid oxidation, decreased significantly( P<0.05), while the expression of stearoyl-CoA desaturase(Scd1)mRNA, a lipid synthesis related gene, increased significantly( P<0.01). Further immunofluorescence analysis showed that the proportion of slow muscle fibers decreased and that of fast muscle fibers increased in continuous light group(both P<0.05). Conclusion:The process of ectopic deposition of lipid in skeletal muscle in mice induced by continuous light exposure may be related to the remodeling of skeletal muscle fibers.

[Abstract] Objective: To investigate the effect of HMGB1 gene on the growth of human epithelial ovarian cancer xenografts in nude mice, and to lay a foundation for finding new targets for the treatment of ovarian cancer. Methods: Human epithelial ovarian cancer SKOV3 cells in logarithmic growth phase were selected to establish a human epithelial ovarian cancer xenograft model in nude mice. Nude mice with successful model establishment were randomly divided into control group and HMGB1-siRNA group. On the 7th, 9th, 11th, 14th, and 16th days after cell inoculation, the same amount of saline and HMGB1-siRNA were respectively injected into two groups of mice under the armpit.After 3 weeks, the nude mice were sacrificed by cervical dislocation, the tumor tissues were separated, and the volume of the tumor was measured. The apoptosis of transplanted tumor cells was detected by Tunnel staining. The expressions of HMGB1, STAT3 and p-STAT3 were detected by Western blotting. The expression of vascular endothelial growth factorA(VEGF-A) and microvascularization were detected by immunohistochemistry. Results: Compared with the control group, the growth of tumor volume slowed down in HMGB1 siRNA group, and on the 21st day, the tumor volume of HMGB1-siRNA group was significantly smaller than that of the control group (P<0.05). HMGB1-siRNA successfully knocked down the expression of HMGB1 mRNA in transplanted tumor tissue. The apoptosis rate of tissue cells in HMGB1-siRNA group was significantly increased ([34±8]% vs [6±2]%, P=0.04), and the expressions of HMGB1 and p-STAT3 were significantly reduced (P<0.05). The expression of VEGF-Aand the number of microvessels were significantly lower than those of the control group (both P<0.05). Conclusion: Knockdown of HMGB1 gene reduces the expression of VEGF-A and microvessel formation possibly by inhibiting the HMGB1/STAT3 signaling pathway, thereby promoting the apoptosis of tumor tissues and slowing the growth of xenografts.

Objective To explore the association between estimated glomerular filtration rate (eGFR) and prognosis of acute ischemic stroke (AIS) patients who were treated by intravenous thrombolysis with recombinant tissue plasminogen activator (rt-PA).Methods We consecutively screened AIS patients who were treated by intravenous thrombolysis with rt-PA from January 2006 to September 2016 in Tangshan Gongren Hospital.According to eGFR value of patients at admission,the eligible patients were divided into two groups:normal eGFR group (eGFR ≥ 90 ml ? min-1 ? 1.73 m-2) and decreased eGFR group (eGFR ＜ 90 ml? min-1 ? 1.73 m-2).The incidence of symptomatic intracerebral hemorrhage (SICH),early neurological deterioration (END) at 24 hours and seven days after thrombolysis,mortality within seven days and 90 days,and excellent recovery at 90 days were compared between the two groups.The OR with 95％ CI and the adjusted OR with 95％ CI were analyzed by univariate and multivariate Logistic regression models.Results A total of 258 patients were enrolled,including 182 cases in the normal eGFR group and 76 cases in the decreased eGFR group.After adjusting for the potential confounders,multivariate Logistic regression analysis showed that the rates of SICH (13.2％ (10/76) vs 3.3％ (6/182),OR =3.859,95％ CI 1.313-11.341),END at 24 hours (21.1％ (16/76) vs 8.2％ (15/182),OR =2.958,95％ CI 1.347-6.495) and seven days (32.9％ (25/76) vs 12.6％ (23/182),OR =3.129,95％ CI 1.555-6.293),mortality within seven days (22.4％ (17/76) vs 6.0％ (11/182),OR =4.079,95％ CI 1.588-10.477) and 90 days (23.7％ (18/76) vs 9.9％ (18/182),OR =2.457,95％ CI 1.050-5.749) were higher in the decreased eGFR group than in the normal eGFR group.On the other hand,the chance of excellent recovery at 90 days (22.4％ (17/76) vs 43.4％ (79/182),OR =0.435,95％ CI 0.229-0.824) was less in the decreased eGFR group than in the normal eGFR group.Conclusion Decreased eGFR may not only increase the risks of SICH,END and death,but also reduce the chance of 90-day excellent recovery in AIS patients after intravenous thrombolysis with rt-PA.

Two strains of porcine reproductive and respiratory syndrome virus (PRRSV) were isolated in 2006 and 2016 and designated as FZ06A and FZ16A, respectively. Inoculation experiments showed that FZ06A caused 100% morbidity and 60% mortality, while FZ16A caused 100% morbidity without death. By using genomic sequence and phylogenetic analyses, close relationships between a Chinese highly pathogenic PRRSV strain and the FZ06A and FZ16A strains were observed. Based on the achieved results, multiple genomic variations in Nsp2, a unique N-glycosylation site (N³³→K³³), and a K151 amino acid (AA) substitution for virulence in the GP5 of FZ16A were detected; except the 30 AA deletion in the Nsp2-coding region. Inoculation experiments were conducted and weaker virulence of FZ16A than FZ06A was observed. Based on our results, a 30 AA deletion in the Nsp2-coding region is an unreliable genomic indicator of a high virulence PRRSV strain. The Nsp2 and GP5 differences, in addition to the virulence difference between these two highly pathogenic PRRSV strains, have the potential to be used to establish a basis for further study of PRRSV virulence determinants and to provide data useful in the development of vaccines against this economically devastating disease.
