ObjectiveThis paper aims to investigate the material basis of the anti-inflammatory efficacy and mechanism of action of Bushen Tongdu prescription （BSTDP）. MethodsThe chemical components of BSTDP and its blood-absorbed components in vivo were systematically identified by using ultra-performance liquid chromatography-linear ion trap-electrostatic field orbitrap high-resolution mass spectrometry （UPLC-LIT-Orbitrap-MS）. Network pharmacology was employed to screen blood-absorbed bioactive components and potential targets of this formula. A protein-protein interaction （PPI） network of core targets was constructed to conduct enrichment analysis. Molecular docking was further utilized to verify the binding affinity between key components and targets. The inflammatory model was established and verified in vivo by using a transgenic zebrafish Tg （mpx： GFP）. At three days post-fertilization （3 dpf）， larvae of zebrafish were randomly assigned to blank group， model group， positive drug dexamethasone acetate group （75 μmol·L^-1）， and BSTDP groups with low， medium， and high doses （500， 1 000， and 2 000 mg·L^-1）. The distribution and quantity of neutrophils in the yolk sac region were observed under a fluorescence microscope. The mRNA expression levels of key genes in the toll-like receptor 4 （TLR4）/myeloid differentiation factor 88 （MyD88）/nuclear factor kappa-B （NF-κB） signaling pathway and inflammatory factors including interleukin （IL）-1β， IL-6， and tumor necrosis factor-α （TNF-α） were detected by Real-time quantitative polymerase chain reaction （Real-time PCR）. ResultsA total of 120 chemical components were identified in BSTDP， among which 26 original components were confirmed by using serum pharmacochemical methods. A total of 227 common targets linking rheumatoid arthritis （RA） and the blood-absorbed components were screened by network pharmacology. It is suggested that pseudobrucine， vomicine， sinapine， rehmannioside， cinnamyl alcohol glycoside， and methylephedrine exert anti-inflammatory effects by acting on core targets including protein kinase B1 （Akt1）， signal transducer and activator of transcription 3 （STAT3）， tumor necrosis factor （TNF）， TLR4， mitogen-activated protein kinase 14 （MAPK14）， and phosphatidylinositol-4，5-bisphosphate 3-kinase catalytic subunit α （PIK3CA）， thereby modulating multiple signaling pathways such as TLR4 and NF-κB. In vivo verification in zebrafish demonstrates that the maximum tolerable concentration of Bushen Tongdu Formula is 2 000 mg·L^-1. Compared to those in the blank group， zebrafish in the model group showed a significantly higher number of neutrophils in the yolk sac region （P<0.01） and rising mRNA levels of TLR4， MyD88， NF-κB， TNF-α， IL-6， and IL-1β （P<0.01）. Compared to that in the model group， the number of neutrophils was significantly reduced in BSTDP groups with medium and high doses， as well as the dexamethasone acetate group （P<0.05， P<0.01）. There was no statistically significant difference in the low dose group. The mRNA expression levels of TLR4， MyD88， NF-κB， TNF-α， IL-6， and IL-1β were significantly down-regulated （P<0.05， P<0.01）. ConclusionThis paper identifies the material basis of the efficacy of BSTDP， demonstrating that the formula can exert an anti-inflammatory effect through the TLR4/MyD88/NF-κB signaling pathway. The results provide scientific experimental evidence for its further clinical application.

ObjectiveThis study focused on the marketed Chinese patent medicines for the treatment of Functional Diarrhea （FDr） in China and their prescription characteristics， in order to provide support for the clinical application and research and development of anti-FDr Chinese patent medicines. MethodsCollect the information of Chinese patent medicines that have been marketed to treat FDr， use Microsoft Excel 2021 software to conduct preliminary data collation and statistical analysis， and use the ancient and modern medical record cloud platform （V2.3.9） to analyze the standardized Chinese patent medicine prescriptions from the aspects of drug nature and taste， medication characteristics and prescription rules. Results147 kinds of FDr Chinese patent medicines were included in this study. There are a total of 40 varieties of FDr Chinese patent medicines suitable for children； The distribution of dosage forms is mainly pills， tablets， and capsules. 110 prescriptions were screened， among which the proportion of Chinese patent medicines for the treatment of spleen deficiency syndrome was the highest； The top three drug use frequency were licorice， Atractylodes macrocephala， and Poria cocos； The medicinal properties are mainly warm and flat， and the medicinal taste is mostly pungent， sweet and bitter， and most of them belong to the two meridians of the spleen and stomach； The association rules analysis obtains 20 strong association pairing sets； Three drug combinations were obtained by cluster analysis. ConclusionFDr Chinese patent medicine shows unique value in clinical application， especially in the field of children. However， there are still problems such as strong professionalism in the indication expression of drug instructions， limited coverage of the medical insurance catalog， and lack of high-level evidence-based medicine and pharmacoeconomic evidence. To this end， in the future， efforts should be made to build a multi-level evidence-based evidence system， improve medication compliance， and deepen research on syndrome-based medication laws， so as to enhance the clinical application value and scientific connotation of FDr Chinese patent medicines.

ObjectiveTo investigate the therapeutic effect of sequential administration of Dihuang Baoyuan granules （DHBY， the prescription for consolidating body resistance） and Fuling Yunhua granules （FLYH， the prescription for treating symptoms） on spontaneous type 2 diabetes mellitus （T2DM） in mice. MethodsAccording to the fasting blood glucose （FBG） level， 12-week-old db/db mice were randomized into six groups： model， DHBY （18.02 g·kg^-1）， FLYH （14.80 g·kg^-1）， sequential administration 1 （SEQ-1， DHBY 18.02 g·kg^-1+FLYH 14.80 g·kg^-1）， sequential administration 2 （SEQ-2， FLYH 14.80 g·kg^-1+DHBY 18.02 g·kg^-1）， and dapagliflozin （Dapa， 1.3 mg·kg^-1）. The m/m mice in the same litter were selected as the normal group. The mice were administrated with corresponding drugs by gavage for 8 consecutive weeks. During the 8 weeks of drug administration and 2 weeks after withdrawal， the retinal thickness， FBG， hemoglobin A1c （HbA1c）， and insulin were determined， and histopathological changes of the pancreas， liver， kidney， and retina were observed by hematoxylin-eosin （HE） staining. ResultsCompared with the model group， SEQ-1 for 4 weeks lowered the FBG level （P<0.05）， raised the insulin level， decreased the triglyceride （TG） level （P<0.05）， increased the number of optic ganglion cells and diminished vacuolar degeneration of pancreatic islet and liver. SEQ-2 lowered FBG and HbA1c levels （P<0.05）， rose the insulin level， increased the retinal thickness and the number of optic ganglion cells （P<0.05）， and alleviated vacuolar degeneration of pancreatic islet and liver. Two weeks after drug withdrawal， Dapa tended to increase FBG and HbA1c compared with those at the time of drug withdrawal. However， the levels of FBG and HbA1c in the SEQ-2 group remained decreasing （P<0.05）. ConclusionSEQ-1 and SEQ-2 can lower the blood glucose level and ameliorate diabetic retinopathy， and SEQ-2 outperformed DHBY and FLYH in lowering the blood glucose level. Moreover， SEQ-2 can maintain the blood glucose-lowering effect after drug withdrawal.

Objective To explore the effect of management model of clinical pharmacists participating in multidisciplinary collaborative diagnosis and treatment(MDT)for new anti-tumor drugs in the national medical insurance drug negotiation(hereinafter referred to as"national negotiation"),including efficacy,safe-ty,economy and rationality.Methods The medical records of 326 cases using novel anti-tumor drugs by na-tional negotiation and conforming to the including and excluding standards in this hospital from July 2018 to June 2023 were retrospectively analyzed.The patients were divided into the MDT group(n=122)and non-MDT group(n=204).The patients diagnosed as non-small cell lung cancer(NSCLC)in the two groups were extracted and defined as the MDT-NSCLC subgroup(n=41)and non-MDT-NSCLC subgroup(n=77).The progression-free survival(PFS),overall survival(OS),disease control rate(DCR)and the indexes such as survival quality and medical quality control were compared between the groups.Results The median PFS in the two groups was 12.7 months and 8.0 months,the median OS was 75.2 months and 56.3 months,DCR was 96.72％and 81.86％respectively,and the differences were statistically significant(P＜0.05).The COX multivariate regression analysis indicated that the HR value of clinical pharmacists participating in MDT was higher than the other influencing factors.The median PFS time in the MDT-NSCLC subgroup and non-MDT-NSCLC subgroup was 10.5 months and 6.7 months,DCR was 97.30％and 75.64％respectively,and the differences were statistically significant(P＜0.05),the median OS time was 55.1 months and 40.3 months respectively,and the difference was statistically significant(P＞0.05).The COX multivariate regression anal-ysis indicated that the HR value with clinical pharmacists participating in MDT was higher than the other in-fluencing factors;The adverse reaction occurrence rate in the MDT group and non-MDT group was 45.9％and 58.3％respectively,and the difference was statistically significant(P＜0.05).The KPS score after treatment in the MDT group was higher than that in the non-MDT group,and the difference was statistically significant;in the aspect of medical quality control,the average drug proportion in the MDT group and non-MDT group was 63.93％and 64.54％respectively,the rational drug rate of comments on prescription was 98.36％and 88.73％respectively,the patient satisfaction average value was 90.69 points and 87.36 points respectively and the differences were statistically significant(P＜0.05).Conclusion Clinical pharmacists participating in MDT related to novel anti-tumor drugs by national negotiation is beneficial to improve the therapeutic effects,living quality and patient satisfaction,also benefit to management and control of off-label drug use and medical quality control indexes.

Objective To evaluate the association of different obesity phenotypes and their components with the risk of cognitive impairment in older Chinese adults,and to assess the association between obesity and cognitive impairment in different cognition-related genetic backgrounds.Methods A cross-sectional study based on the West China Health and Aging Cohort was conducted.Logistic regression was applied to estimate the association of obesity phenotypes and components with cognitive impairment in older Chinese adults stratified by APOE gene and polygenic risk scores.Results A total of 7 316 participants were enrolled,of whom 1 820 had cognitive impairment.Weight gains were associated with a reduced risk of cognitive impairment(odds ratio[OR]=0.96,95%CI,0.95-0.97).Being overweight with a normal waist-to-hip ratio was a protective factor for cognition(OR=0.74,95%CI,0.61-0.90),whereas the coexistence of elevated waist-to-hip ratio and overweight did not increase the risk of cognitive impairment.Sarcopenia was associated with an elevated risk of cognitive impairment.This association was found in both overweight(OR=2.03,95%CI,1.71-2.41)and non-overweight older adults(OR=1.86,95%CI,1.58-2.20),and was significant across all polygenic risk score strata.Conclusion Increasing body mass may serve as a key protective factor against cognitive decline in older adults.Having sarcopenia and obesity is associated with an elevated risk of cognitive impairment,independent of genetic susceptibility.

AIM:To compare the effects of 0.01% with 0.05% atropine eye drops on pupil diameter(PD)and intraocular pressure(IOP)in myopic children.METHODS: Prospective non-randomized controlled study. A total of 232 myopic children who treated at the Department of Ophthalmology, the Second People's Hospital of Puyang from March 2021 to February 2022 were included. They were divided into 0.01% atropine eye drops group(81 cases), 0.05% atropine eye drops group(77 cases), and control group(74 cases)according to patients' will, respectively. The control group received placebo eye drops(isotonic excipient). The PD and IOP of the three groups of patients were measured before medication and at 6 and 12 mo after medication.RESULTS: Finally, 181 cases(181 eyes)(with all right eye data included in the study)completed a 1-year follow-up, with a loss to follow-up rate of 22.0%(51/232). Among them, 62 cases(62 eyes)belonged to the 0.01% atropine eye drops group, 54 cases(54 eyes)belonged to the 0.05% atropine eye drops group, and 65 cases(65 eyes)belonged to the control group. There was no significant difference in baseline PD and IOP among the three groups(all P<0.05). After 12 mo of medication, the changes in PD among the 0.01% atropine eye drops group, 0.05% atropine eye drops group, and control group were 0.79±0.70, 1.29±0.66, and 0.06±0.74 mm, respectively(P<0.001). The change in PD in the 0.05% atropine eye drops group was significantly greater than that in both the 0.01% atropine eye drops group and the control group. Similarly, the change in PD in the 0.01% atropine eye drops group was significantly greater than that in the control group(all P<0.05). After 12 mo of medication, the changes in IOP among the 0.01% atropine eye drops group, 0.05% atropine eye drops group, and control group were -0.70±1.94, -0.22±1.79, and 0.25±2.03 mmHg, respectively(P<0.05). The changes in IOP in the 0.05% atropine eye drops group showed statistically significant difference compared to both the 0.01% atropine eye drops group and the control group(all P>0.05), and the changes in IOP in the 0.01% atropine eye drops group were statistically significant compared to the control group(P<0.05). Multivariate linear regression analysis revealed that baseline refractive error and baseline PD were significant factors influencing the change in PD among children treated with atropine eye drops(β=0.230, 95%CI: 0.005-0.455, SE=0.114, t=2.025, P=0.045; β=-0.562, 95%CI: -0.729--0.396, SE=0.084, t=6.697, P<0.001). Additionally, baseline IOP was significant factor influencing the change in IOP among children in the atropine eye drop groups(β=-0.285, 95%CI: -0.439--0.131, SE=0.078, t=3.662, P<0.001).CONCLUSION: The PD of myopic children increased after using 0.01% and 0.05% atropine eye drops, and the change in PD after using 0.05% atropine eye drops was significantly greater than that of 0.01% atropine eye drops. No risk was found in the use of 0.01% and 0.05% atropine eye drops and elevated IOP.

Objective:To explore the clinical characteristics and variant of CREBBP gene in a fetus with Rubinstein-Taybi syndrome (RSTS). Methods:A fetus with RSTS diagnosed at the Third Affiliated Hospital of Zhengzhou University in August 2022 was selected as the study subject. Clinical data, amniotic fluid sample of the fetus and peripheral blood samples of its parents were collected for whole exome sequencing (WES). Candidate variant was verified by Sanger sequencing.Results:Foot malformation, cerebellar vermis agenesis, brain agenesis, polysyndactyly of the big toes and other phenotypes were found by prenatal ultrasound. WES revealed that the fetus has harbored a heterozygous c. 4684G>T (p.E1562*) variant in exon 28 of the CREBBP gene (NM_004380.3), which was de novo in origin. Based on the guidelines from the American College of Medical Genetics and Genomics (ACMG), the variant was predicted to be pathogenic (PVS1+ PS2_Moderate+ PM2_Supporting). After genetic counseling, the couple had opted to terminate the pregnancy and refused autopsy for the fetus. Conclusion:The c. 4684G>T (p.E1562*) variant of the CREBBP gene probably underlay the RSTS in this fetus. The newly discovered variant has enriched the mutational spectrum of the CREBBP gene and illustrated that WES is an efficient tool for the prenatal diagnosis of RSTS.
