Objective To clarify the active ingredients and the potential molecular mechanism of Guben Qushi Huayu Prescription in treating psoriasis recurrence.Methods An ultra performance liquid chromatography-quadrupole time-of-flight mass spectrometry(UPLC-Q-TOF/MS)was applied to analyze the whole formula and the constituents absorbed into blood of Guben Qushi Huayu Prescription,and molecular docking technology was used to study the binding affinity of the constituents absorbed into blood with psoriasis-related immunomodulatory proteins such as CD69 and CD103 proteins.Results Mass spectrometry analysis identified 21 active ingredients such as paeoniflorin in Guben Qushi Huayu Prescription,including several known anti-inflammatory and immunomodulatory compounds.Analysis of the constituents absorbed into blood identified 11 ingredients,including paeoniflorin,that may affect the course of psoriasis through blood circulation.Molecular docking studies revealed that the constituents absorbed into blood,including astilbin,isoastilbin,chlorogenic acid,neochlorogenic acid,cryptochlorogenic acid,helicine,paeoniflorin,ononin,all had high binding affinities with CD69 and CD103 proteins.Conclusion This research reveals the main active ingredients of Guben Qushi Huayu Prescription and their potential mechanism for regulating the recurrence of psoriasis by mass spectrometry and molecular docking technology,contributing to providing scientific basis for further pharmacological research and clinical application.

Objective To investigate the effects of acupoint application at Tianshu(ST25)combined with kidney-warming and spleen-invigorating therapy on clinical efficacy,intestinal function,and the expressions of Toll-like receptor 4(TLR4)and nuclear factor kappa-B(NF-κB)in patients with ulcerative colitis(UC).Methods A total of 100 UC patients with depletion and deficiency of spleen-kidney complicated with internal accumulation of pathogenic dampness syndrome,treated in the Department of Proctology,Shanghai Municipal Hospital of Traditional Chinese Medicine Affilated to Shanghai University of Traditional Chinese Medicine from June 2022 to June 2024,were selected and randomly divided into four groups(Groups A,B,C,D)using a random number table method,with 25 patients in each group.Group A received standard mesalazine treatment.Group B received Kidney-Warming and Spleen-Invigorating Formula(composed of Psoraleae Fructus,Myristicae Semen,Euodiae Fructus,Schisandrae Chinensis Fructus,Codonopsis Radix,Poria,Atractylodis Macrocephalae Rhizoma,etc.)combined with standard mesalazine treatment.Group C received acupoint application at Tianshu(the medicinal paste for application composed of Caryophylli Flos,Cinnamomi Cortex,Atractylodis Macrocephalae Rhizoma,Euodiae Fructus,Coptidis Rhizoma,etc.)combined with standard mesalazine treatment.Group D received Kidney-Warming and Spleen-Invigorating Formula+acupoint application at Tianshu+standard mesalazine treatment.All groups were treated continuously for 12 weeks.The time for disappearance of clinical symptoms was compared among the four groups.Serum immune cytokines[β-defensin-1,total immunoglobulin A(IgA),interleukin-6(IL-6),tumor necrosis factor-alpha(TNF-α)],peripheral blood levels of TLR4 and NF-κB,protein expression levels of TLR4 mRNA and NF-κB p65 mRNA in intestinal mucosal tissue,and changes in intestinal microbiota were observed before and after treatment.The clinical efficacy of the four groups was evaluated.Results(1)Compared to the other three groups,Group D had the shortest time for disappearance of clinical symptoms such as abdominal pain,diarrhea,mucopurulent bloody stools,and tenesmus(P＜0.05).The time for disappearance of various clinical symptoms in Groups B and C was similar(P＞0.05)but was shorter than that in Group A(P＜0.05).(2)After treatment,the serum levels of β-defensin-1,IgA,IL-6,and TNF-α in all four groups were significantly lower than those before treatment(P＜0.05).Post-treatment intergroup comparisons showed statistically significant differences(P＜0.01),with Group D exhibiting the greatest reduction,significantly lower than the other three groups(P＜0.05).The levels in Groups B and C were similar(P＞0.05)but were lower than those in Group A(P＜0.05).(3)After treatment,the peripheral blood levels of TLR4 and NF-κB,and the protein expression levels of TLR4 mRNA and NF-κB p65 mRNA in intestinal mucosal tissue showed a decreasing trend in all four groups(P＜0.05).Post-treatment intergroup comparison results were statistically significant(P＜0.01),with Group D showing the greatest reduction,significantly lower than the other three groups(P＜0.05).All above levels in Groups B and C were similar(P＞0.05)but were lower than those in Group A(P＜0.05).(4)After treatment,the relative contents of Bifidobacterium and Lactobacillus increased(P＜0.05),while those of Saccharomyces and Clostridium decreased(P＜0.05)in Groups B,C,and D.Post-treatment intergroup comparison results were statistically significant(P＜0.01).Group D showed a significant increase in Bifidobacterium and Lactobacillus and a significant decrease in Saccharomyces and Clostridium,with the magnitude of change significantly greater than that in the other three groups(P＜0.05).The quantities of these bacteria in Groups B and C were similar(P＞0.05),but the improvement was significantly greater than that in Group A(P＜0.05).(5)After 12 weeks of treatment,Group D had the highest total effective rate at 100.00％(25/25).The total effective rates of Groups B and C were similar,both at 84.00％(21/25),but were higher than that of Group A(56.00％,14/25).The intergroup difference was statistically significant(x2=16.310,P＜0.01).Conclusion The comprehensive treatment regimen of acupoint application at Tianshu combined with Kidney-Warming and Spleen-Invigorating Formula,on the basis of standard mesalazine treatment,has a positive impact on UC patients with depletion and deficiency of spleen-kidney complicated with internal accumulation of pathogenic dampness syndrome.This treatment method can effectively improve clinical symptoms,regulate β-defensin-1 and IgA levels,enhance immune defense function,downregulate the expression levels of TLR4 and NF-κB,and alleviate inflammatory response.Compared to monotherapies,it is more effective on improving treatment outcomes.

Objective:To summarize the clinical features of Chlamydia pneumoniae pneumonia (CPP) in children. Methods:Case series study. Clinical data of 10 children with CPP hospitalized in Department No.2 of Respiratory Medicine of Beijing Children′s Hospital, Capital Medical University from January 2019 to August 2024 were retrospectively collected, including general information, clinical manifestations, chest imaging, laboratory examination and treatment. The clinical features and prognosis were summarized.Results:Among the 10 children with CPP, 7 were male and 3 were female. The age of onset was 11.2 (10.3, 13.1) years. The course were 17 (7, 23) days. Cough occurred in 9 cases with wet cough in 7 cases, while moderate and high fever occurred in 6 cases. Besides, chest pain occurred in 4 cases, rash and hemoptysis occurred in 1 case respectively. High density mass shadow was found in 7 cases chest CT imaging, accompanied by air bronchogram sign, surrounded by halo sign, 6 cases of which were distributed under the pleura, while patchy consolidation in the remaining 3 cases. Pulmonary embolism was present in 2 cases. Among the 10 children with CPP, bilateral lung involvement was found in 3 cases and unilateral lung involvement in 7 cases. The white blood cell count was 10.21 (7.45, 11.64)×10 9/L and the proportion of neutrophils was 0.69 (0.63, 0.71). C-reactive protein increased in 7 cases, with the level of 33 (16, 77) mg/L. D-dimer increased slightly in 3 cases (0.393, 0.396, 0.739 mg/L). Serum Chlamydia pneumoniae-IgM antibody test was positive in 6 cases. Chlamydia pneumoniae nucleic acid test by bronchoalveolar lavage fluid (BALF) next-generation sequencing was positive in 6 cases. Both serum IgM antibody and BALF nucleic acid tests were positive in 2 cases. Among the 10 children with CPP, azithromycin alone was used in 5 cases, while glucocorticoid was added in 1 case. Due to poor response to azithromycin in 4 cases, doxycycline was replaced in 3 cases and minocycline was replaced in 1 case, while glucocorticoid was added in 2 cases. Moxifloxacin combined with glucocorticoid therapy was adopted in 1 case with long course after the poor response to azithromycin and doxycycline. All patients were cured finally. Conclusions:CPP mostly occurs in elderly children. The main clinical manifestations include cough, fever and chest pain. The common chest imaging feature is subpleural high-density mass shadow with halo sign. Pulmonary embolism is present in a few cases. Nucleic acid detection and (or) serology is helpful for etiological diagnosis. Some cases need glucocorticoid therapy.
