ObjectiveTo provide a basis for the establishment of an ideal animal model of allergic asthma by statistically analyzing the modeling characteristics and the selection of indicators of the available models. MethodsWe retrieved the relevant articles from China National Knowledge Infrastructure（CNKI）， VIP， Wanfang Data， SinoMed， and PubMed with "allergic asthma" as the keyword and the time interval from January 2019 to January 2024. Through integrating the literature and extracting data， we used Excel 2021 to create a personal database and sorted out the animal strains， genders， allergenic substances， modeling routes， and test indicators and methods. Excel 2021， Cytoscape 3.10.2， and SPSS Modeler 18.0 were then used to analyze the relevant characteristics of the animal models. ResultsA total of 418 articles were included in the database， and the comparative analysis showed that the most frequently used animal strain for modeling was BALB/c mice， and female animals were mostly used. The main modeling method was sensitization by intraperitoneal injection of ovalbumin （OVA）， which was combined with intranasal inhalation. The test indicators mainly included appearance signs， cellular analysis， lung histopathology， lung function indicators， and protein and gene expression in the lung. The test methods mainly involved pathological staining， enzyme-linked immunosorbent assay， immunohistochemistry， immunofluorescence， Western blot， and polymerase chain reaction（PCR） assays. ConclusionThere is no recognized modeling method or evaluation standard for the animal models of allergic asthma. Based on the results of data analysis， the OVA-induced allergic asthma model in BALB/c mice is recommended. The main criteria for evaluating the success of modeling are the general behavioral changes， the morphological changes of the airway and inflammatory cell infiltration in the lung tissue， the changes of pro-inflammatory and anti-inflammatory cytokines in the serum， and the alterations of inflammatory cells in the bronchoalveolar lavage fluid.

A 20-year-old male patient presented to the Department of Dermatology of Peking Union Medical College Hospital with complaints of an 8-year history of facial scarring, swelling of the lower limbs, and a 4-year history of scalp thickening. Physical examination showed thickening furrowing wrinkling of the skin on the face and behind the ears, ciliary body hirsutism, blepharoptosis, and cutis verticis gyrate. Both lower limbs were swollen, especially the knees and ankles. The skin of the palms and soles of the feet was keratinized and thickened. Laboratory examination using bone and joint X-ray showed periostosis of the proximal middle phalanges and metacarpals of both hands, distal ulna and radius, tibia and fibula, distal femurs, and metatarsals.Genetic testing revealed two variants in SLCO2A1, c.1658T > A and c.96+4A > C.Through multidisciplinary consultation, we confirmed the diagnosis of pachydermoperiostosis.

AIM: To investigate the correlation of degree of myopia in adolescents with axial length, corneal curvature and axial ratio.METHODS: Cross-sectional study. A total of 246 adolescents(492 eyes)aged 8-18 years consecutively enrolled for orthokeratology lens fitting at the Fifth Affiliated Hospital of Zhengzhou University between 2021 and 2023 were included based on random sampling method, with 447 eyes finally included due to the elimination of 45 eyes that did not meet the inclusion criteria. Biometric measurements under scotopic conditions assessed axial length(AL), corneal radius of curvature(CR), and AL/CR ratio. Cycloplegic refraction determined spherical equivalent(SE), classifying eyes into mild(216 eyes)or moderate(231 eyes)myopia groups. Furthermore, the correlation of degree of myopia with AL, CR and AL/CR was analyzed by multiple linear regression analysis.RESULTS: A statistically significant difference in myopia severity was observed between the 8-12-year-old and 13-18-year-old age groups(all P<0.001). There were statistically significant differences between mild and moderate groups in SE, AL and AL/CR(all P<0.001). Linear regression analysis revealed significant negative correlations of SE with AL and AL/CR(r=-0.531, -0.598, all P<0.001). The areas under the ROC curve(AUC)for predicting moderate myopia were 0.812(95% CI: 0.773-0.852)for AL/CR combined with gender and age, 0.800(95% CI: 0.759-0.841)for AL/CR alone, 0.726(95% CI: 0.680-0.773)for AL alone, and 0.548(95% CI: 0.494-0.601)for CR alone. The optimal AL/CR cut-off value for predicting moderate myopia was 3.189(sensitivity: 0.632, specificity: 0.852), suggesting its potential as a clinical threshold.CONCLUSION: In adolescents with mild-to-moderate myopia, AL/CR, AL, and SE showed significant negative correlations. The combination of AL/CR with gender and age demonstrated the highest diagnostic accuracy for SE. AL/CR shows independent predictive value for myopia degree in adolescents, irrespective of refractive status.

AIM: To study the degree of astigmatism, axial distribution and axial symmetry pattern of binocular astigmatism in primary and secondary school students aged 7-18 years with myopia.METHODS:A total of 239 cases(478 eyes)of primary and secondary school students aged 7-18 years who underwent keratoplasty for myopia correction at the Fifth Affiliated Hospital of Zhengzhou University from 2020 to 2022 were randomly selected, and optometry was performed under ciliary muscle paralysis and was statistically analyzed.RESULTS:Astigmatism degree: 0.25 to 1.00 D accounted for 78.5%, 1.25 to 2.00 D accounted for 17.1%, and >2.00 D accounted for 4.4%. The axial distribution of astigmatism: 86.6% was astigmatism with the rule, 5.9% was astigmatism against the rule, and 7.5% was oblique astigmatism; both genders and different astigmatism degrees were dominated by astigmatism with the rule, and there were differences with the other two axes(both P<0.05). Axial symmetry pattern of astigmatism: the median axial difference in astigmatism between the direct symmetry model and the mirror symmetry model was 7° and 10°, respectively, with no statistical significance in both models(P=0.158), and there was no difference between the two in gender, degree of astigmatism, and axial distribution of astigmatism, but in the age group of 7-12 years old, the difference between the axial astigmatism of the direct symmetry model and the mirror symmetry model was statistically significant(P=0.027).CONCLUSION:The axial distribution of binocular astigmatism in myopic primary and middle school students is mostly astigmatism with the rule; the degree of astigmatism is more common from 0.25 to 1.0 D; however, there is no tendency for axial symmetry pattern of astigmatism.

We analysed the similarities between theory of The Inner Canon of Yellow Emperor （《黄帝内经》） and modern sleep medicine on sleep and wakefulness， and initially constructed the "eye-brain" sleep regulation system. The similarities between the sleep theories in The Inner Canon of Yellow Emperor and modern sleep medicine research are described from three perspectives： the anatomical basis of sleep physiology， the pathogenesis of sleep disorder pathology， and the mechanism of sleep disorder treatment. It is found that the regulation of sleep and wakefulness in both medicine theories is based on the "eye" and "brain" as the main control centres， and there exists a "eye-brain" pathway to regulate sleep and wakefulness in the human body. Based on this， the "eye-brain" sleep regulation theory is constructed， in order to find an effective way to solve the pathogenesis and treatment strategy of sleep disorders.

A rapid analytical method for simultaneous determination of 32 kinds of multi-residue veterinary drugs in eggs was developed using a modified QuEChERS technique based on a reduced graphene oxide-coated melamine sponge(r-GO@MeS)by ultra-high performance liquid chromatography-tandem mass spectrometry(UPLC-MS/MS).The influences of graphene oxide(GO)concentrations,sponge dosages,and purification modes on drug recoveries were investigated during the purification process.The optimal purification conditions involved using a GO concentration of 0.5 mg/mL,a sponge dosage of 6.0 cm3/mL,and a dynamic purification mode of 5 extrusion cycles.Separation was achieved using an Agilent Eclipse Plus C18 RRHD column(100 mm×2.1 mm,1.8 μm),and quantitative analysis was performed by the external standard method using an electrospray ionization source(ESI)in multiple reaction monitoring(MRM)mode.The results showed that all 32 kinds of veterinary drugs exhibited good linear correlation with coefficients greater than 0.999,and matrix effects(MEs)ranging from?7.8%to 18.9%.The limits of detection(LODs)and quantification(LOQs)ranged from 0.2 to 10.2 μg/kg and from 0.6 to 28.0 μg/kg,respectively.The recoveries for the three spiked levels were in the range of 66.5%?117.5%,with intra-day and inter-day precision(Relative standard deviation)below 13.3%and 16.3%,respectively.The synthetic r-GO@MeS exhibited efficient matrix purification without the need of high-speed centrifugation or strong magnetic field assistance.This significantly shorted the sample pretreatment time and improved the convenience of the matrix purification process.Combined with UPLC-MS/MS,the method was suitable for the rapid determination of multi-residue veterinary drugs in eggs.

Objective:To explore the influence of acupoint catgut embedding combined with Xuezhikang capsule on lipid metabolism and antioxidation effect in patients with statin intolerance and hyperlipidemia of spleen-kidney yang deficiency syndrome.Methods:Randomized controlled trial. A total of 82 patients with statin intolerance and hyperlipidemia who were treated in Shuguang Hospital Affiliated to Shanghai University of Traditional Chinese Medicine , Shanghai Puto Area Central Hospital, and Lingyun community health Service center, Xuhui District from July 2020 to June 2022 were selected and randomly divided into two groups with 41 patients in each group by odd-even ball method. The two groups were given diet and exercise guidance, and the control group was given Xuezhikang capsule orally on this basis, and the observation group was given poly(l-lactide-co-glycolide) (PLGA) thread acupoint catgut embedding on the basis of the control group. Both groups were treated continuously for 3 months. The TCM syndromes were scored before and after treatment, and body weight (BW), waist circumference (WC) and body mass index (BMI) were recorded. The levels of TC, TG, HDL-C and LDL-C were detected by fully automatic biochemical analyzer. The levels of serum SOD, GSH-Px and total antioxidant capacity (TAOP) were measured by ELISA. The level of serum endothelin-1 (ET-1) was assessed by radioimmunoassay. Color Doppler ultrasound diagnostic instrument was used to detect the brachial artery flow-mediated dilation (FMD) and nitroglycerin-mediated dilation (NMD).Results:The scores of chilly sensation and cold limbs [(1.27±0.12) vs. (1.46±0.16), t=6.08], loose stool [(1.41±0.16) vs. (1.63±0.18), t=5.85], fatigue [(1.45±0.15) vs. (1.57±0.17), t=3.39], dizziness [(1.15±0.11) vs. (1.26±0.13), t=4.14] and loss of appetite [(1.21±0.13) vs. (1.39±0.15), t=5.81] in observation group after treatment were significantly lower than those in the control group ( P<0.01). BW [(68.03±6.57)kg vs. (71.55±6.76)kg, t=2.39], WC [(85.13±4.63)cm vs. (87.35±4.85)cm, t=2.12] and BMI [(27.35±2.84)kg/m 2vs. (29.18±3.05)kg/m 2, t=2.81]were lower than those in the control group ( P<0.05). The levels of serum TC [(3.15±0.13)mmol/L vs. (3.38±0.17)mmol/L, t=6.88], TG [(1.98±0.11)mmol/L vs. (2.21±0.15)mmol/L, t=7.92]and LDL-C [(2.46±0.26)mmol/L vs. (3.04±0.33)mmol/L, t=8.84]were significantly lower compared with those in control group ( P<0.01) while the level of HDL-C [(1.88±0.24)mmol/L vs. (1.74±0.21)mmol/L, t=2.81]was higher than that of the control group ( P<0.01). The levels of serum SOD [(57.82±5.84)μg/L vs. (55.06±5.61)μg/L, t=2.18], GSH-Px [(96.51±9.52)U/L vs. (92.26±9.25)U/L, t=2.30]and TAOP [(6.21±0.57)U/L vs. (5.94±0.54)U/L, t=2.20]were significantly higher compared to control group ( P<0.05). Serum ET-1 [(60.43±4.36) pg/L vs. (63.71±4.68) pg/L, t=3.28] level was significantly lower than that in control group ( P<0.01), while FMD [(12.48±1.02)% vs. (11.34±0.95)%, t=5.24] and NMD [(15.12±1.24)% vs. (14.44±1.18)%, t=2.54] were significantly higher than those in control group ( P<0.01). Conclusion:The combination of acupoint catgut embedding and Xuezhikang capsule can reduce the scores of TCM syndromes, lower the obesity and blood lipids, enhance the antioxidant function and improve the vascular endothelial function in patients with statin intolerance and hyperlipidemia.

Objective To study the correlation between traditional Chinese medicine(TCM)constitution and pathogenic factors in patients with ankylosing spondylitis(AS).Methods One hundred patients of AS and their family members who had medical consultation in the Fifth Hospital of Xi'an(i.e.,Shaanxi Hospital of Integrated Traditional Chinese and Western Medicine)in August 2019 and September 2020 were selected as the study subjects.The guidelines of Classification and Determination of Traditional Chinese Medicine Constitution issued by the China Association of Chinese Medicine were adopted to determine the traditional Chinese medicine(TCM)constitution types of the study subjects.The sociodemographic information,living habits,clinical symptoms,and TCM constitution types of the AS patients and their family members were collected by means of questionnaires and clinical investigations,and then the pathogenic factors of the patients with AS were investigated.The binomial Logistic regression model was used to analyze the correlation between TCM constitution types and pathogenic factors in patients with AS.Results(1)Among the 100 AS patients,the majority of them had the biased constitutions,and the biased constitutions with the occurrence frequency in descending order were yang deficiency constitution,qi deficiency constitution,and damp-heat constitution,which accounted for 33.00%,14.00%,and 18.00%,respectively.(2)The prevalence rates of AS in the first-,second-,and third-degree relatives of AS patients were 56.25%,40.00%and 25.00%,respectively.For the positive rates of human leukocyte antigen B27(HLA-B27)in AS patients and their family members,HLA-B27 in AS patients was all positive,while the positive rates of HLA-B27 in the first-,second-,and third-degree relatives of AS patients were 44.31%,30.67%and 15.63%,respectively.(3)The results of regression analysis showed that the disease duration of AS patients was significantly correlated with qi deficiency constitution,the grading of sacroiliac arthritis was correlated with qi stagnation constitution,and age was correlated with blood stasis constitution(P＜0.05 or P＜0.01).The results indicated that disease duration and age were the important factors affecting the constitution types of AS patients,and disease duration was closely related to qi deficiency while age was closely related to blood stasis.Conclusion AS is a highly hereditary autoimmune disease,and its onset is associated with HLA-B27.Yang deficiency is the basic constitution type of AS,and damp-heat constitution is the main constitution type in the progression of AS(especially in the active stage of the disease).The prolongation of the disease will exacerbate the illness condition of AS and then the manifestations of qi deficiency will be more obvious.

Objective By using the bibliometrics method,the literature about Yinchenhao decoction was visualized and analyzed to explore its research hot spot and frontier.Methods The related literatures on Yinchenhao decoction were retrieved from CNKI database,and CiteSpace 6.1.R6 software was used to analyze the authors,institutions and key words,and the key words were clustered to draw a visual atlas.Results A total of 856 articles were included,and the number of articles showed a fluctuating upward trend.There were 764 authors and 513 related key words,including clinical application,experimental study and signaling pathway of Yinchenhao decoction.Conclusion Although Yinchenhao decoction is a commonly used clinical prescription for liver disease,there is a lack of studies on the mechanism of action and molecular level.Future research hot spot should focus more on large sample randomized controlled clinical studies and experimental studies,so as to provide new directions for researchers.

Objective:To compare the effect of delaying progression of myopia in children between defocus incorporated multiple segments (DIMS) spectacle lens and orthokeratology.Methods:A nonrandomized controlled clinical study was conducted.A total of 390 children (390 eyes) with myopia who were treated in the First Affiliated Hospital of Zhengzhou University from January 2018 to December 2020 were included, with the spherical equivalent (SER) of -0.75 to -6.00 D. According to the willingness of patients and patients' guardians, the subjects were divided into DIMS group, orthokeratology group and single-vision spectacle lens group, with 130 cases (130 eyes) in each group, wearing DIMS spectacle lenses, standard or astigmatic design orthokeratology and conventional single-vision full-correction aspheric spectacle lenses, respectively.The SER of the eyes was measured using an automatic computerized refractometer in combination with subjective refraction before and one year after lens wear, and the axial length (AL) of the eyes was measured using IOLMaster.A total of 327 patients in the three groups met the inclusion and exclusion criteria, including 107 in the DIMS group, 112 in the orthokeratology group, and 104 in the single-vision spectacle lens group.All the right eyes were included in this study.The changes in SER and AL before and after wearing lenses for 1 year were compared among the three groups.The relationship between AL and SER changes and baseline data in the DIMS group was evaluated by Pearson linear correlation analysis.The study followed the Declaration of Helsinki, and the study protocol was reviewed and approved by the Ethics Committee of the First Affiliated Hospital of Zhengzhou University (No.2023-KY-0174-002). The subjects and their guardians were fully aware of the purpose and methodology of the study, and voluntarily signed an informed consent form.Results:There were statistically significant overall differences in SER and AL at different time points among the three groups (SER: Fgroup=7.065, P=0.009; Ftime=183.730, P<0.001.AL: Fgroup=6.151, P=0.014; Ftime=175.290, P<0.001). One year later, the differences in SER and AL changes among the three groups were statistically significant ( F=7.065, P=0.009; F=6.151, P=0.014). The SER and AL of each group after 1 year was greater than the baseline, with the SER and AL and their changes significantly smaller in orthokeratology group and DIMS group than in single-vision spectacle lens group and greater in DIMS group than in orthokeratology group, showing statistically significant differences (all at P<0.05). Compared with single-vision spectacle lenses, wearing orthokeratology for 1 year can inhibit SER and AL progression by 58.3% and 59.0%, and wearing DIMS frame glasses for 1 year can inhibit SER and AL progression by 46.9% and 43.6%.The percentage of eyes with no change in SER was 5.77%(6/104), 24.11%(27/112) and 17.76%(19/107) in the single-vision spectacle lens group, orthokeratology group and DIMS group, respectively, and the percentage of AL was 0.00%(0/104), 8.93%(10/112) and 7.48%(8/107), respectively, showing statistically significant differences among the three groups ( χ2=9.316, 8.676; both at P<0.001). The AL change in the DIMS group was weakly negatively correlated with age ( r=-0.252, P=0.006). Conclusions:Wearing DIMS spectacle lenses is not as effective as orthokeratology in delaying myopia in children, but it is significantly better than wearing conventional single-vision spectacle lenses.
