Objective:To analyze the efficacy of enzyme replacement therapy and anti-drug antibody production in children with Fabry disease.Methods:The clinical data of 7 children with Fabry disease treated with enzyme replacement therapy for more than 1 year at Children′s Hospital of Zhejiang University School of Medicine from July 2021 to June 2024 were retrospectively analyzed. The basic information and the changes of related clinical indicators before and after treatment were collected. Paired sample t test was used to compare renal function, left heart mass index, pain score and other related indexes before and after treatment. The anti-drug antibodies were detected by enzyme-linked immunosorbent assay. Results:A total of 6 boys and 1 girl were included. The age of diagnosis was (12.2±1.8) years. After 1 year of enzyme replacement therapy, the abnormal substrate globotriaosylsphingosine and brief pain inventory scores of all children were significantly lower than those before treatment ((16±11) vs. (63±42) μg/L, 22±19 vs. 45±29, t=3.88, 3.43, both P<0.05). There were no significant differences in glomerular filtration rate, urinary microalbumin to creatinine and left heart mass index before and after treatment ((124±35) vs. (136±26) ml/(min·1.73 m 2), (9.3±8.3) vs. (3.8±2.5) mg/g, (38±9) vs. (33±6) g/m 2.7, t=1.33, 1.74, 1.19, all P>0.05). Patients 4, 5 and 6 developed anti-drug antibodies at 1 month, 4 months and 1 month after medication, respectively. Patient 4 had persistently high anti-drug antibody titers (absorbance 3.65-3.73) accompanied by urticaria, elevated globotriaosylsphingosine and worsening clinical symptoms. Conclusions:The enzyme replacement therapy can effectively improve the clinical symptoms and reduce the level of globotriaosylsphingosine in children with Fabry disease. The anti-drug antibody is common in patients after long-term enzyme replacement therapy and may diminish the efficacy, which needs dynamic monitoring.

Objective:To investigate damaging effects of clomifene citrate(CC)on endometrial stromal cells(hEndoSCs),and to study effects of spermidine on autophagy and inflammatory cytokine expression in damaged endometrial stromal cells.Methods:Groups were firstly divided into control group,spermidine group,clomiphene group(CC group),CC+Spermidine group.MTT assay was used to detect cell survival rate of hEndoSCs after co-incubation with different concentrations of CC or Spermidine for 24 h.Con-tent of intracellular reactive oxygen species(ROS)and level of apoptosis in cells of the 4 groups were detected by flow cytometry tech-nique.Western blot was used to detect expressions of autophagy pathway-related proteins ULK1,p-ULK1,LC-3Ⅱ,and apoptosis-re-lated proteins Bax,Bcl-2,Cleaved-caspase 3.RT-qPCR was used to detect mRNA expressions of IL-6,IL-1β and TNF-α.Results:Compared with control group,CC group showed decreased cell survival,increased apoptosis rate,ROS content,Bax,Cleaved-cas-pase 3 expressions,decreased Bcl-2 expression,decreased levels of autophagy-related proteins p-ULK1 and LC-3Ⅱ/Ⅰ,and elevated expressions of inflammatory factors IL-6,IL-1β and TNF-α mRNA(P<0.01).There was no significant changes viability of cells in spermidine group compared with control group(P>0.05).Compared with CC group,cell survival rate in CC+spermidine group was sig-nificantly increased,apoptosis rate,ROS content,Bax and Cleaved-caspase 3 expressions were decreased,Bcl-2 expression was in-creased,expressions of autophagy-related proteins p-ULK1 and LC-3Ⅱ/Ⅰ were elevated,while expressions of inflammatory factors IL-6,IL-1β and TNF-α mRNA were decreased(P<0.01).Conclusion:CC can inhibit endometrial stromal cell proliferation,promote apoptosis,and increase the transcript levels of inflammatory factors IL-6,IL-1β and TNF-α.Spermidine can reduce intracellular ROS in clomiphene-injured endometrial stromal cells by activating cellular autophagy,increase cell survival,and inhibit the expressions of inflammatory factors IL-6,IL-1β and TNF-α.

Objective To evaluate the effectiveness and safety of different Chinese patent medicine in improving blood lipid and microcirculation in coronary heart disease patients with phlegm-blood stasis syndrome based on network meta-analysis.Methods The randomized controlled trials(RCTs)of different Chinese patent medicine in the treatment of blood lipid and microcirculation in coronary heart disease patients with phlegm-blood stasis syndrome were collected by searching CNKI,Wanfang,VIP,SinoMed,PubMed,EMbase,Cochrane Library,and Web of science databases from the establishment of the database to April 3,2023.Literature quality evaluation and network meta-analysis were conducted using Review Manager 5.4 and Stata15.1 software.Results Thirty-seven RCTs were included,with a total sample size of 4 064 cases,involving 15 different Chinese patent medicines.The network meta-analysis showed that the efficacy of Chinese patent medicine combined with conventional Western medicine is often better than that of conventional Western medicine alone.There are no serious adverse reactions.The top three Chinese patent medicines with cumulative probability of total clinical efficacy were Guanmai Zaitong soft extract,Gualoupi Injection and Quyu Xiaoban Capsule.In terms of improving triglyceride(TG)and low-density lipoprotein(LDL-C),the top three Chinese patent medicines were Gualoupi Injection,Huxinkang Tablet and Guanxin Shutong Capsule.In terms of improving plasma viscosity and fibrinogen,the top three Chinese patent medicines were Ginkgo Damo Injection,Gualoupi Injection and Guanxin Shutong Capsule.In terms of improving endothelial function[nitric oxide(NO)and endothelin-1(ET-1)],the top three Chinese patent medicines were Ginkgo Damo Injection,Danlou Tablet and Tongmai Yuxin Pill.In terms of reducing inflammation hypersensitivity C-reactive protein(hs-CRP),the top three Chinese patent medicines were Ginkgo Damo Injection,Huxinkang Tablet and Guanxin Shutong Capsule.Conclusion The current evidence shows that the combination of TCM,which is used for the treatment of phlegm-blood stasis syndrome,with conventional Western medicine in the treatment of coronary heart disease has advantages in improving clinical efficacy,blood lipids and microcirculation.TCM especially for the treatment of phlegm-blood stasis syndrome shows more obvious advantage,such as Guanmai Zaitong soft extract and Gualoupi injection,which can be taken into consideration as part of the clinical guidelines.However,due to the limited number and quality of the included literatures,the research results still need to be verified by more high-quality,multi-center,double-blind randomized trials.The purpose is to provide more reliable evidence-based medical reference.

Objective:To study the occurrence and high risk factors of extrapulmonary complications in premature infants with bronchopulmonary dysplasia（BPD），by calculating cumulative supplementary oxygen exposure（CSO）as a predictive value for reference.Methods:The clinical data，laboratory results，incidence and treatment of complications of premature infants with gestational age<32 weeks and birth weight<1 500g in the First Neonatal Internal Medicine Ward at Shengjing Hospital of China Medical University from January 2020 to December 2022 were collected. According to the occurrence of BPD and the severity of BPD, all children were divided into non-BPD group, mild BPD group and moderate to severe BPD group. According to the complications, children with BPD were divided into white matter injury (WMI)/ retinopathy of prematurity (ROP)/ metabolic osteopathy (MBDP) group and non-WMI/ROP/MBDP group.The occurrence and risk factors of these three complications in children with BPD were summarized.And the prediction index was put forward by single factor analysis and Logistic regression analysis.Results:A total of 405 premature infants were included, including 206 cases in non-BPD group, 128 cases in mild BPD group and 71 cases in moderate to severe BPD group.The gestational age and birth weight of BPD preterm infants were smaller than those of non-BPD preterm infants, and the incidences of asphyxia, multi-dose (two or more) pulmonary surfactant use, patent ductus arteriosus and septicemia in moderate to severe BPD group were higher than those in mild BPD group and non-BPD group. The cumulative oxygen therapy time and invasive mechanical ventilation time in moderate to severe BPD group were also longer than those in mild BPD group and non-BPD group.The differences were all statistically significant（ P<0.05）. Among 199 cases of BPD, there were 68 cases in WMI group and 131 cases in non-WMI group,89 cases in ROP group and 110 cases in non-ROP group,131 cases in MBDP group and 68 cases in non-MBDP group.In multivariate Logistic regression analysis，1-28CSO（ OR=2.042，95% CI 1.102-3.783， P=0.023）,cumulative oxygen therapy time（ OR=1.044，95% CI 1.009-1.080， P=0.012）within 28 days after birth and male（ OR=2.711，95% CI 1.123-6.544， P=0.027）were the risk factors of ROP in children with BPD.1-28CSO（ OR=2.124，95% CI 1.193-3.784， P=0.011），birth weight（ OR=0.040，95% CI 0.005-0.352， P=0.004）and late-onset sepsis（ OR=2.165，95% CI 1.027-4.567， P=0.042）were the risk factors of MBDP in children with BPD.The receiver operating characteristic curve analysis showed that the areas under the curve of 1-28CSO for BPD combined with ROP and MBDP were 0.872（95% CI 0.824-0.921）and 0.779（95% CI 0.711-0.846）, respectively, the sensitivities were 70.8% and 77.9%, the specificities were 88.2% and 72.0%,respectively, and the critical values was 2.900 and 2.125,respectively. Conclusion:The increase of cumulative oxygen therapy time and male may increase the risk of BPD with ROP, low birth weight and the occurrence of late-onset sepsis may increase the risk of BPD with MBDP, and 1-28CSO is a common risk factor for both.1-28CSO has a high predictive value in early evaluation of BPD with ROP and MBDP.

ObjectiveTo explore whether the mechanism of Shuangshen Ningxin capsules （SSNX） in alleviating myocardial ischemia-reperfusion injury （MIRI） in rats is related to the regulation of mitochondrial fission and fusion. MethodThis study focused on Sprague Dawley （SD） rats and ligated the left anterior descending branch of the coronary artery to construct a rat model of MIRI. The rats were divided into the sham operation group， model group， SSNX group （90 mg·kg^-1） and trimetazidine group （5.4 mg·kg^-1）. The activity of superoxide dismutase （SOD） and the content of malondialdehyde （MDA） were detected by micro method. Changes in mitochondrial membrane potential （△Ψm） and the degree of mitochondrial permeability transition pore （mPTP） opening were detected by the chemical fluorescence method. The intracellular adenosine triphosphate （ATP） level was detected by the luciferase assay. The messenger ribonucleic acid （mRNA） and protein expression levels of mitochondrial fission and fusion related factors dynamin-related protein 1 （DRP1）， mitochondrial fission 1 protein （FIS1）， optic atrophy protein 1 （OPA1）， mitochondrial outer membrane fusion protein 1 （MFN1）， and MFN2 were detected by real-time polymerase chain reaction （real-time PCR） and Western blot. ResultCompared with the sham operation group， the model group showed a decrease in serum SOD activity and an increase in MDA content. The opening level of mPTP， the level of △Ψm and ATP content decreased， the protein expressions of mitochondrial fission factors DRP1 and FIS1 increased， and the protein expressions and mRNA transcription levels of fusion related factors OPA1 and MFN1 decreased. Compared with the model group，SSNX significantly increased serum SOD activity， reduced MDA content， increased intracellular ATP level and △Ψm， reduced the opening level of mPTP， downregulated the protein expressions of mitochondrial fission factors DRP1 and FIS1， and increased the mRNA transcription levels and protein expressions of fusion related factors OPA1 and MFN1. ConclusionSSNX inhibits the expressions of mitochondrial fission factors DRP1 and FIS1， and increases the expressions of fusion related factors OPA1 and MFN1， inhibiting mitochondrial fission and increasing mitochondrial fusion， thereby alleviating MIRI.

Objective To investigate the correlation between brain injury and spleen damage in a rat model of acute ischemic stroke and stasis interaction,and its effect on the MCP-1/CCR2 axis,and to provide an experimental basis for the mechanism of brain-spleen inflammatory coupling in spleen lesions caused by acute ischemic stroke.Methods Forty male SD rats were randomly divided into a sham group,carrageenan/yeast stasis syndrome group(carrageenan/yeast,CA/Y),middle cerebral artery occlusion group(MCAO),and middle cerebral artery stasis syndrome group(MCAO CA/Y)with 10 rats in each group.CA/Y and MCAO CA/Y groups were injected with 10 mg/kg carrageenan and 10 mg/kg intraperitoneally on the first day of modeling.2 mg/kg of dry yeast suspension were injected subcutaneously on the second day.MCAO and MCAO CA/Y groups were established by wire embolism on the second day.At 24 h after cerebral infarction modeling,the neurological deficit score was calculated in each group,the percentage of the cerebral infarction area was determined by TTC staining,the spleen weight was measured,and the correlation between the percentage of the cerebral infarction area and spleen weight was analyzed by the Spearman correlation coefficient.Furthermore,the pathological morphology of brain and spleen tissues was observed by hematoxylin-eosin(HE)staining,and chemotactic protein 1(MCP-1)and interferon-γ(IFN-γ)contents were measured in rat plasma by enzyme-linked immunosorbent assays.Western blot was used to detect chemokine C-C-motif receptor 2(CCR2)protein expression in the ischemic side of brain tissue.Results Compared with the sham group,the neurological deficit score,cerebral infarction area,and MCP-1 and IFN-γ contents in plasma were significantly increased(P＜0.01),spleen weight was decreased significantly(P＜0.01),and CCR2 protein expression in brain tissue was significantly upregulated(P＜0.05)in MCAO and MCAO CA/Y groups.Moreover,the area of cerebral infarction was increased significantly(P＜0.01),the spleen weight was decreased significantly(P＜0.01),and CCR2 protein expression in brain and spleen tissues was significantly upregulated(P＜0.05)Compared with the MCAO group,the area of cerebral infarction in the MCAO CA/Y group was significantly increased(P＜0.01)and the spleen weight was decreased significantly(P＜0.05).Spearman correlation analysis showed that the spleen weight was negatively correlated to the percentage of the cerebral infarction area(P＜0.01,r=-0.9711).Pathological morphology observation revealed that the pathological changes in the MCAO CA/Y group were the most serious,cerebral liquefaction necrosis foci were seen in the brain tissue cortex,arrangement of neuronal cells in the lesions was sparse and disordered with volume atrophy and a small number of vacuoles and nuclear solidification,most neuronal cells were degenerated and necrotic,microglia hyperplasia was obvious,small blood vessels were significantly increased,and interstitial lipid degeneration was severe.The density of periarterial lymph sheath cells in some of the spleen tissue was reduced and the marginal area is widened.Conclusions A correlation between brain and spleen injury was found after acute ischemic stroke with stasis and toxin syndrome,and the chemokine signaling axis of MCP-1/CCR2 might be involved in the mechanism of brain-spleen inflammation coupling.

Myocardial ischemia-reperfusion injury （MIRI） is a common injury in the treatment of ischemic heart diseases. MIRI can be categorized as chest impediment and palpitation in traditional Chinese medicine， with the pathogenesis related to Qi and blood disharmony. The simultaneous disorders of Qi and blood are the key mechanism of MIRI， and thus the differentiation of Qi and blood syndromes is the prerequisite for the treatment. The theory of Qi and blood interacting in vessels is proposed by our team based on Qi being the commander of blood and blood being the mother of Qi as well as previous pharmacological studies. Specifically， Qi marshals blood by vessels， and the blood carries Qi by vessels. Accordingly， Qi and blood interact in the vessels. MIRI is accompanied by mitochondrial dysfunction， platelet function abnormality， and vascular endothelial damage， which are correlated with Qi deficiency， blood stasis， and vessel damage， respectively. Mitochondrial， platelet， and vascular endothelial structural and functional changes triggered by their interactions are one of the mechanisms by which Qi deficiency， blood stasis， and vessel damage lead to the occurrence and development of MIRI. By exploring the correlations between Qi and mitochondria， between blood and platelets， and between vessels and blood vessels， we can explain the modern scientific content of the theory of Qi and blood interacting in vessels in traditional Chinese medicine. According to the pathogenesis of Qi and blood disharmony in vessels， we discussed the pharmacological mechanisms of Qi-replenishing medicines， blood-activating medicines， and their combinations in the prevention and treatment of MIRI. On the basis of the research achievements in the prevention and treatment of MIRI by Qi-replenishing and blood-activating Chinese medicines based on the theory of Qi and blood interacting in vessels， we analyzed the effects of these medicines on Qi， blood， and vessels. According to the theory of Qi and blood， this article reveals the theoretical basis and scientific connotations of the prevention and treatment of cardiovascular diseases， with the aim of providing new ideas and references for the clinical application of traditional Chinese medicine in the prevention and treatment of cardiovascular diseases.

Objective:To discuss the effect of Wnt/β-catenin signaling pathway inhibitor methyl 3-｛[(4-methyl-phenyl)sulfonyl]amino ｝ benzoate(MS AB)on the fibrogenic response of the human endometrial stromal cells(HESCs),and to provide the foundation for the application of MSAB in the target therapy of intrauteriue adhesion(JUA).Methods:The normal HESCs were cultured in vitro and divided into two groups:control group and transforming growth factor β1(TGF-β1)group;the HESCs from the adhesion part of the IUA patients were cultured in vitro,regarded as IUA group.Western blotting method was used to detect the expression levels of fibrotic marker protein type Ⅰ collagen α1(COL1A1)in the cells in various groups at different time points(0,12,24,48,and 60 h)after treated with TGF-β1.MTT assay was used to detect the proliferation activities of the cells in various groups.Western blotting method was used to detect the expression levels of the fibrotic marker protein COL1A1,stromal marker proteins such as N-cadherin and α-smooth muscle actin(α-SMA),and Wnt/β-catenin signaling pathway-related protein β-catenin in the cells in control and IUA groups.Based on the MSAB concentrations,the normal HESCs were divided into 0(control),0.25,0.50,0.75,and 1.00 μmol·L-1 MSAB groups,and MTT assay was used to detect the survival rates of the cells in various groups.After treated with MSAB,the normal HESCs were divided into control group(normal HESCs),TGF-β1 group(10 μg·L-1 TGF-β1 induced normal HESCs for 24 h then the drug was withdrawn,replaced with complete culture medium,and the cells continued to be cultured for 24 h),and MSAB group(10 μg·L-1 TGF-β1 induced normal HESCs for 24 h then the drug was withdrawn,replaced with a complete medium containing 0.75 μmol·L-1 MSAB and the cells continued to be cultured for 24 h).Real-time fluorescence quantitative PCR(RT-qPCR)method was used to detect the expression levels of epithelial-mesenchymal transition(EMT)-related transcription factors Snail,Slug,Smuc,ZEB1,and ZEB2,and COL1A1 mRNA in the cells in various groups.Western blotting method was used to detect the expression levels of COL1A1,N-cadherin,α-SMA,β-catenin,and c-myc proteins in the cells in various groups.Results:Compared with control group(after treated with TGF-β1 for 0 h),the expression levels of COL1A1 proteins in the HESCs after treated with TGF-β1 for 12,24,48,and 60 h in TGF-β1 group were increased(P＜0.05 or P＜0.01).Compared with control group,there was no significant difference in the proliferation activity of the HESCs in IUA and TGF-β1 groups(P＞0.05).Compared with control group,the expression levels of COL1A1,β-catenin,N-cadherin,and α-SMA proteins in the cells in IUA group were increased(P＜0.05 or P＜0.01).Compared with control group,the survival rates of the cells in 0.75 and 1.00 μmol·L-1 MSAB groups were decreased(P＜0.05 or P＜0.01).Compared with control group,the expression levels of Snail,Slug,and COL1A1 mRNA in the cells in TGF-β1 group were increased(P＜0.05 or P＜0.01);compared with TGF-β1 group,the expression levels of Snail,Slug,and COL1A1 mRNA in the cells in MSAB group were decreased(P＜0.05 or P＜0.01).Compared with control group,after treated with TGF-β1 for 24 h,the expression levels of COL1A1,N-cadherin,α-SMA,β-catenin,and c-myc proteins in the cells in TGF-β1 group were increased(P＜0.01);compared with TGF-β1 group,the expression levels of COL1A1,N-cadherin,α-SMA,β-catenin,and c-myc proteins in the cells in MSAB group were decreased(P＜0.05 or P＜0.01).Conclusion:MSAB can inhibit the fibrogenic responses of the HESCs in vitro,and the results provide the theoretical basis for the application of MSAB in the target therapy of IUA.
