Guided by "triple-yang combination of diseases"， it is believed that the core pathogenesis of acute respiratory infection in children is external cold and internal heat， and triple-yang combination， and its transmission can be divided into two forms. First， the taiyang syndrome usually happens earlier， presenting as the exterior cold in taiyang is not yet resolved， and inward penetration of exterior cold transfers into heat， which combines the disease of shaoyang and yangming； second， yangming meridian already has internal heat， then meets with taiyang meridian externally infected with pathogenic qi， both internal and external pathogens accumulated in the two meridians and affected shaoyang meridian. It is proposed that the therapeutic method should release the exterior and clean the interior， and treat the triple-yang at the same time， with self-prescribed Chaige Gaore Formula （柴葛高热方） as the empirical formula for the treatment of acute respiratory infections in children.

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.

AIM To study the protective effects and mechanism of pueraria isoflavones on myocardial injury in ovariectomized rats.METHODS Thirty-six rats were randomly divided into the sham operation group,the model group,the estradiol valerate group(0.1 mg/kg)and the low,medium and high dose pueraria isoflavones groups(55,110,220 mg/kg).In contrast to the rats of the sham operation group having their small pieces of adipose tissue removal around the ovaries,rats of the other groups had their bilateral ovaries excised,followed by the 16-week corresponding oral drug administration 2 weeks later at a once daily frequency for,6 days a week.At the end of the 16th week,the rats had their hemodynamics[systolic pressure(SBP),diastolic pressure(DBP),mean pressure(MBP),left ventricular systolic pressure(LVSP),left ventricular diastolic pressure(LVMP),and the maximum rate of increase and decrease of left ventricular pressure during isovolumic contraction(±dp/dtmax)]detected by PowerLab;their cardiac pathological changes observed by HE staining;their levels of creatine kinase(CK),lactate dehydrogenase(LDH),total cholesterol(TC),triglyceride(TG),high density lipoprotein cholesterol(HDL-C),low density lipoprotein cholesterol(LDL-C)and glucose(Glu)in plasma detected by biochemical analyzer;their myocardial level of adenosine triphosphate(ATP)detected by colorimetry;their mRNA expressions of glucose transporter 4(GLUT4),lactate dehydrogenase A(LDHA),carnitine palmitoyl transferase-1(CPT-1α),acyl coenzyme A carboxylase(ACC),liver kinase B1(LKB1),adenylate-activated protein kinase(AMPK)and peroxisome proliferator-activated receptor γ coactivator factor 1α(PGC-1α)detected by RT-qPCR;and their myocardial expressions of energy metabolism related proteins LKB1,p-AMPK/AMPK and PGC-1α detected by Western blot.RESULTS Compared with the model group,the pueraria isoflavones groups displayed decreased levels of SBP,DBP,MBP,LVSP,LVMP(P＜0.05,P＜0.01);increased-dp/dtmax(P＜0.05,P＜0.01);improved myocardial fibrinolysis,gap widening and inflammatory infiltration caused by ovariectomy;decreased activities of LDH and CK(P＜0.05);increased myocardial ATP level(P＜0.05,P＜0.01);decreased levels of TC,TG,LDL-C and Glu(P＜0.05,P＜0.01);increased HDL-C level(P＜0.05,P＜0.01);increased myocardial mRNA expressions of GLUT4,LDHA,CPT-1α,ACC,LKB1,AMPK and PGC-1α(P＜0.05,P＜0.01);and increased protein expressions of myocardial LKB1,p-AMPK/AMPK and PGC-1α(P＜0.05,P＜0.01).CONCLUSION Pueraria isoflavones are protective to myocardial injury in ovariectomized rats,and the mechanism may lie in the improvement of energy metabolism-related myocardial proteins via LKB1/AMPK/PGC-1α signaling pathway.

Objective To analyze the risk factors for postoperative gastroparesis syndrome (PGS) in gastric cancer patients undergoing laparoscopic radical gastrectomy (LRG) and to construct and validate a nomogram prediction model for PGS. Methods The clinical data of 439 gastric cancer patients were retrospectively analyzed. Patients were divided into PGS group and control group based on whether PGS occurred within 2 months after surgery. Logistic regression analysis was used to screen for risk factors of PGS in LRG patients, and a nomogram prediction model was constructed based on the screening results. The discriminative ability of the nomogram was assessed by the receiver operating characteristic (ROC) curve, and its consistency was evaluated by the calibration curve. Results Among 439 patients, 52 developed PGS, with an incidence rate of 11.85%. The proportions of patients aged ≥60 years, complicating with diabetes, having a history of abdominal surgery, complicating with pyloric obstruction, having surgery duration ≥4 hours, and intraoperative anastomosis type of B-Ⅱ were higher in the PGS group than those in the control group (P < 0.05). The results of multivariate Logistic regression analysis showed that diabetes, a history of abdominal surgery, pyloric obstruction, surgery duration ≥4 hours, and intraoperative anastomosis type of B-Ⅱ were risk factors for PGS in LRG patients (P < 0.05). Internal validation results showed that the area under the ROC curve was 0.839 (95%CI, 0.773 to 0.905), the calibration curve fitted well, and the Hosmer-Lemeshow goodness-of-fit test result was good(χ²=9.078, P=0.247). Conclusion Diabetes, a history of abdominal surgery, pyloric obstruction, surgery duration ≥4 hours, and intraoperative anastomosis type of B-Ⅱ are risk factors for PGS in LRG patients. The nomogram constructed based on these factors can effectively predict the risk of PGS in LRG patients.

This study aimed to investigate the effect and molecular mechanism of sinomenine on proliferation, apoptosis, metastasis, and combination with inhibitors in human hepatocellular carcinoma HepG2 cells and SK-HEP-1 cells. The effect of sinomenine on the growth ability of HepG2 and SK-HEP-1 cells were investigated by CCK-8 assay, colony formation assay, and BeyoClick~(TM) EdU-488 staining. The effect of sinomenine on DNA damage was detected by immunofluorescence assay, and the effect of sinomenine on apoptosis of human hepatocellular carcinoma cells was clarified by Hoechst 33258 staining and CellEvent~(TM) Cystein-3/7Green ReadyProbes~(TM) reagent assay. Cell invasion assay and 3D tumor cell spheroid invasion assay were performed to investigate the effect of sinomenine on the invasion ability of human hepatocellular carcinoma cells in vitro. The effect of sinomenine on the regulation of protein expression related to the protein kinase B(Akt)/mammalian target of rapamycin(mTOR)/signal transducer and activator of transcription 3(STAT3) signaling pathway in HepG2 and SK-HEP-1 cells was examined by Western blot. Molecular docking was used to evaluate the strength of affinity of sinomenine to the target cysteinyl aspartate specific proteinase-3(caspase-3) and STAT3, and combined with CCK-8 assay to detect the changes in cell viability after combination with STAT3 inhibitor JSI-124 in combination with CCK-8 assay. The results showed that sinomenine could significantly reduce the cell viability of human hepatocellular carcinoma cells in a concentration-and time-dependent manner, significantly inhibit the clonogenic ability of human hepatocellular carcinoma cells, and weaken the invasive ability of human hepatocellular carcinoma cells in vitro. In addition, sinomenine could up-regulate the cleaved level of poly ADP-ribose polymerase(PARP), a marker of apoptosis, and down-regulate the protein levels of p-Akt, p-mTOR, and p-STAT3 in human hepatocellular carcinoma cells. Molecular docking results showed that sinomenine had good affinity with the targets caspase-3 and STAT3, and the sensitivity of sinomenine to hepatocellular carcinoma cells was diminished after STAT3 was inhibited. Therefore, sinomenine can inhibit the proliferation and invasion of human hepatocellular carcinoma cells and induce apoptosis, and the mechanism may be attributed to the activation of caspase-3 signaling and inhibition of the Akt/mTOR/STAT3 pathway. This study can provide a new reference for the in-depth research and clinical application of sinomenine and is of great significance to further promote the scientific development and utilization of sinomenine.

Objective:To observe the prevention and control effect of 1% atropine on the progression of form deprivation myopia (FDM) in guinea pigs and the potential biological mechanism.Methods:Sixty-nine 3-week-old tricolor guinea pigs with normal refraction were randomly divided into a normal control group ( n=19), a FDM group ( n=19), a FDM+ atropine group ( n=19), and an atropine group ( n=12). No intervention was given to guinea pigs in normal control group.The FDM model was established by covering the right eye of guinea pigs with a semitransparent latex facemask for 4 weeks in FDM and FDM+ atropine groups.For the FDM+ atropine group, 1% atropine gel was topically administered to the form-deprived right eyes once a day for 4 weeks.For the atropine group, the right eye was treated with 1% atropine gel once a day for 4 weeks.Refraction and axial length of guinea pigs were measured by retinoscopy and ophthalmic A-scan ultrasonography respectively at baseline, experiment week 2 and week 4.In experiment week 4, eyeballs were enucleated to make sections via the paraffin wax processing procedure, and the microstructural and ultrastructural changes of the sclera were observed under the light microscope and transmission electron microscope, respectively.The isobaric tags for relative and absolute quantitation labeling combined with liquid chromatography-tandem mass spectrometry were used to identify the differentially expressed proteins.Use and care of the animals complied with the Regulation for the Administration of Affairs Concerning Experiment Animals by State Science and Technology Commission.The study protocol was approved by the Institutional Animal Care and Use Committee of Tianjin Medical University (No.TJYY2020111028). Results:There were statistically significant differences in the diopter of guinea pigs at different time points among the four groups ( Fgroup=138.892, P<0.001; Ftime=167.270, P<0.001). Compared with normal control group, the diopter of guinea pigs in FDM group at experiment weeks 2 and 4, and FDM+ atropine group at experiment week 4 developed toward myopia, showing statistically significant differences (all at P<0.001). Compared with FDM group, the diopter of guinea pigs in FDM+ atropine group at experiment weeks 2 and 4 developed toward hyperopia, showing statistically significant differences (both at P<0.001). There were statistically significant differences in the axial length of guinea pigs at different time points among the four groups ( Fgroup=32.346, P<0.001; Ftime=353.797, P<0.001). The axial lengths of FDM group at experiment weeks 2 and 4 and FDM+ atropine group at experiment week 4 were longer than those of normal control group, and the axial lengths in FDM+ atropine group at experiment weeks 2 and 4 were shorter than those in FDM group, and the differences were statistically significant (all at P<0.001). The collagenous fibers of posterior sclera of guinea pigs were loose and disordered in FDM group, and were regular in FDM+ atropine group.The posterior scleral thickness of normal control group, FDM group, FDM+ atropine group and atropine group was (141.74±16.98), (101.46±9.15), (112.74±6.24) and (134.30±18.19) μm, respectively, with a statistically significant difference ( F=6.709, P=0.005). The posterior sclera was significantly thinner in FDM group than in normal control group and FDM+ atropine group (both at P<0.05). The diameter of posterior scleral collagen fiber gradually increased from inside to outside in normal control group, FDM+ atropine group and atropine group, and the diameters of the inner, middle and outer posterior scleral collagen fibers were smaller in FDM group than in normal control group.Proteomic analysis revealed 85 differentially expressed proteins (fold change>1.30) between FDM group and normal control group, FDM+ atropine group and FDM group, of which 38 were up-regulated and 47 were down-regulated after atropine treatment.Gene Ontology enrichment analysis showed that biological processes mainly involved were biological regulation, cell process, localization and metabolic process.Molecular function mainly involved were binding, catalytic activity, molecular function regulator, structural molecule activity and transporter activity.Cell components mainly involved were in cellular anatomical entity, intracellular and protein-containing complex. Conclusions:Atropine can increase the diameter of scleral collagen fibers in guinea pigs of FDM model, improve the arrangement of scleral collagen fiber, inhibit scleral thinning.The mechanism of atropine to control myopia progression is closely related to the tight junction between scleral cells, cytoskeleton and extracellular matrix remodeling.

Objective:To evaluate the effect of short-term topical administration of atropine eye drops with various concentrations and frequencies on eye safety in children.Methods:A double-blind randomized controlled trial was conducted.Sevevty-two children with ametropia or pre-myopia (72 eyes) were enrolled in Tianjin Medical University Eye Hospital from December 2020 to January 2022.The subjects were randomly divided into 0.01% atropine group, 0.02% atropine group and 0.04% atropine group according to a random number table, with 24 cases (24 eyes) in each group.Automatic refraction with an automatic computer optometry device, subjective refraction with a phoropter, intraocular pressure with a non-contact tonometer, axial length by optical biometrics, the amplitude of accommodation (AMP) by the push-up method, pupil diameter with pupilometer, near visual acuity at 33 cm with a standard logarithmic visual acuity chart, tear evaluation with Keratograph 5M and Ocular Surface Disease Index (OSDI) questionnaire survey were performed among all subjects.One drop of 0.01%, 0.02%, and 0.04% atropine was administrated to the study eye according to grouping, and the pupil diameter was measured every 10 minutes until the pupil did not enlarge three times, then the data after a single treatment of the three groups were recorded.After one-week application of the corresponding concentration of atropine eye drops once at night, the data after one-week treatment were recorded.For the next week, the application frequency of 0.01% and 0.02% atropine groups changed to once daily in the morning and evening, and 0.04% atropine group maintained once at night, then the data after two-week treatment were recorded.Data of the right eyes were analyzed.The changes in pupil diameter, AMP and other eye parameters before and after atropine eye drops of the three groups were compared.This study adhered to the Declaration of Helsinki and the study protocol was approved by the Ethics Committee of Tianjin Medical University Eye Hospital (No.2020KY[L]-51). All subjects and their guardians were fully informed of the method and purpose of this study before entering the cohort.Written informed consent was obtained from guardians.Results:Pupil diameters of 0.01%, 0.02% and 0.04% atropine groups were (5.59±0.48), (5.35±0.76) and (5.65±0.43)mm before treatment respectively, (7.00±0.68), (7.17±0.58) and (8.40±1.71)mm after a single treatment, (6.67±0.62), (6.56±0.65) and (7.60±0.69)mm after one-week treatment, (6.96±0.49), (7.04±0.53) and (7.60±0.36)mm after two-week treatment.There were significant differences in pupil diameter at different time points after treatment among the three groups ( Fgroup=9.430, P<0.001; Ftime=156.620, P<0.001). The AMP of 0.01%, 0.02% and 0.04% atropine groups were (12.94±3.02), (13.25±2.81) and (13.42±2.60)D before treatment respectively, (11.62±2.61), (11.53±2.06) and (9.64±1.93)D after a single treatment, (11.14±2.61), (11.33±2.33) and (8.30±1.18)D after one-week treatment, (9.99±1.81), (8.72±1.25) and (8.76±2.12)D after two-week treatment.There was no significant difference in the AMP among the three groups ( Fgroup=2.800, P=0.063). In the three groups, the AMP at different time points after treatment were significantly lower than that before treatment ( Ftime=61.400, P<0.001). There was no difference in spherical equivalent refraction, intraocular pressure, near visual acuity, axial length, first none-invasive tear break-up time, average none-invasive tear break-up time, tear meniscus height and OSDI score among the three groups ( Fgroup=0.030, 0.630, 1.420, 0.580, 0.140, 0.120, 0.340, 0.142; all at P>0.05). There were significant differences in spherical equivalent refraction, intraocular pressure, first none-invasive tear break-up time, average none-invasive tear break-up time, tear meniscus height and OSDI score at different time points between before and after medication among the three groups ( Ftime=12.560, 4.730, 4.720, 5.220, 3.720; all at P<0.05). Conclusions:Varying pupil dilation and AMP reduction occur after the use of different concentrations of atropine and are more severe at higher concentrations.Increased administration frequency of atropine is associated with more pupil dilation and AMP reduction, but there is no intolerable adverse effect.
