Objective To investigate the clinical efficacy and safety of Zishen Jianpi Quyu Formula in treating patients with migraine without aura in the postmenstrual period of kidney deficiency and blood stasis type.Methods A total of 104 patients with migraine without aura of kidney deficiency and blood stasis type were randomly divided into the control group and the trial group,with 52 cases in each group.The control group was treated with Flunarizine Hydrochloride Capsules,and the trial group was treated with Zishen Jianpi Quyu Formula on the basis of treatment for the control group.One menstrual cycle constituted a course of treatment,and the treatment covered a total of two courses(eight weeks).The changes of traditional Chinese medicine(TCM)syndrome score,migraine attack frequency,duration of migraine headaches,visual analogue scale(VAS)score of migraine headache intensity,Headache Impact Test-6(HIT-6)score and hemorheology indexes in the two groups before and after treatment were observed.Moreover,the efficacy for TCM syndrome and clinical safety in the two groups were evaluated.Results(1)After two courses of treatment,the total effective rate of the trial group was 90.38%(47/52),and that of the control group was 69.23%(36/52),the intergroup comparison(by chi-square test)showed that the efficacy for TCM syndrome in the trial group was significantly superior to that of the control group(P＜0.05).(2)After treatment,the TCM syndrome scores of the patients in both groups were significantly lower than those before treatment(P＜0.05),and the reduction of TCM syndrome score in the trial group was significantly superior to that in the control group(P＜0.05).(3)After treatment,the migraine attack frequency,duration of migraine headaches,VAS scores of migraine headache intensity in the two groups of patients were significantly improved compared with those before treatment(P＜0.05),and the improvement of migraine headache parameters in the trial group was significantly superior to that in the control group(P＜0.05).(4)After treatment,the HIT-6 score in the two groups was decreased significantly compared with those before treatment(P＜0.05),and the decrease of HIT-6 score in the trial group was significantly superior to that in the control group(P＜0.05).(5)After treatment,hemorheology indexes(including plasma viscosity,whole blood high-shear viscosity,whole blood low-shear viscosity,fibrinogen,and hematocrit)in the two groups were improved compared with those before treatment(P＜0.05),and the improvement of each of hemorheology indexes in the trial group was significantly superior to that in the control group(P＜0.05).(6)During treatment,no serious adverse events occurred in the two groups,which was of high safety.Conclusion Zishen Jianpi Quyu Formula exerts remarkable clinical efficacy in treating patients of migraine without aura in the postmenstrual period of kidney deficiency and blood stasis type.The formula is effective on improving the TCM syndromes and migraine attacks of the patients,achieving the efficacy of milder headache,lower attack frequency and shorter duration,more stability hemorheology indexes and higher safety.

This study aimed to investigate the effect of iron overload on the transplant outcomes of pediatric patients with severe aplastic anemia (SAA) undergoing allogeneic hematopoietic stem cell transplantation (allo-HSCT). A retrospective analysis was conducted on the clinical data of 74 children with SAA who received allo-HSCT at the Hematology Department of Wuhan Children’s Hospital between January 2018 and August 2022. Children with iron overload (serum ferritin >1 000 μg/L) before transplantation had a longer disease course, received more red blood cell transfusions, and had a higher number of CD34 + cells infused. Moreover, iron overload significantly delayed the reconstitution of regulatory T cells after transplantation, increasing the incidence of hemorrhagic cystitis and grade Ⅲ-Ⅳ acute graft-versus-host disease after transplantation. However, iron overload did not significantly affect the overall survival and failure-free survival rates of the children.

Objective:To investigate the safety and efficacy of mitoxantrone liposome in the treatment of children with high-risk acute myeloid leukemia(AML).Methods:The children with high-risk AML who received the mitoxantrone liposome regimen at Wuhan Children's Hospital from January 2022 to February 2023 were collected as the observation group,and the children with high-risk AML who received idarubicin regimen were enrolled as controls,and their clinical data were analyzed.Time to bone marrow recovery,the complete remission rate of bone marrow cytology,the clearance rate of minimal residual disease,and treatment-related adverse reactions were compared between the two groups.Results:The patients treated with mitoxantrone liposome showed shorter time to recovery of leukocytes(17 vs 21 day),granulocytes(18 vs 24 day),platelets(17 vs 24 day),and hemoglobin(20 vs 26 day)compared with those treated with idarubicin,there were statistical differences(P＜0.05).The effective rate and MRD turning negative rate in the observation group were 90.9％and 72.7％,respectively,while those in the control group were 94.1％and 76.4％,with no statistical difference(P＞0.05).The overall response rate of the two groups of patients was similar.Conclusion:The efficacy of mitoxantrone liposome is not inferior to that of idarubicin in children with high-risk AML,but mitoxantrone liposome allows a significantly shorter duration of bone marrow suppression and the safety is better.

Objective:To investigate the prognostic value of minimal residual disease(MRD)detected by multi-parameter flow cytometry(MFC)in pediatric patients with acute myeloid leukemia(AML)after induction chemotherapy.Methods:A retrospective study was conducted on 97 pediatric patients initially diagnosed with AML at Wuhan Children's Hospital from August 2015 to December 2022.The study analyzed the results of MRD detection using MFC after the first and second cycles of induction chemotherapy,and its association with prognosis were analyzed.Results:Following the first cycle of induction treatment,57 of the 97 patients tested positive for MRD(MRD1+,58.8％).Subsequently,19 patients remained MRD positive(MRD2+,19.6％)after the second cycle of induction treatment.Kaplan-Meier survival analysis showed that the estimated 3-year overall survival(OS)rate of the 37(64.9％)MRD1+patients who underwent transplantation was significantly higher than that of the 20(35.1％)MRD1+patients who did not undergo transplantation(84.6％vs 40.0％,P=0.0001).Among the 35 MRD1+MRD2-patients,the 3-year OS rate of the 25 children who underwent transplantation was higher than that of the 10 children who did not undergo transplantation(87.2％vs 70.0％,P=0.3229).The 3-year OS rate of the 19 MRD1+MRD2+patients was lower than that of the 35 MRD1+MRD2-patients(57.4％vs 81.8％,P=0.059).In the 19 MRD2+patients,the 3-year OS rate of the 12 children who underwent transplantation was significantly higher than that of the 7 children who did not undergo transplantation(80.8％vs 14.3％,P=0.0007).There was no significant difference in 3-year OS between the 12 MRD1+MRD2+patients and 25 MRD1+MRD2-patients,both treated with transplantation(80.8％vs 87.2％,P=0.8868).In those not treated with transplantation,the 7 MRD1+MRD2+patients had a significantly lower 3-year OS compared with the 10 MRD1+MRD2-patients(14.3％vs 70.7％,P=0.0114).Further multivariate analysis indicated that MRD2 positivity and transplantation were both independent prognostic factors(P=0.031,0.000),while MRD1 positivity was not significantly associated with the overall prognosis of 97 patients(P=0.902).Conclusion:MRD positivity following the second cycle of induction chemotherapy is an independent risk factor for unfavorable outcomes in children with AML.MRD2 positivity indicates a poorer prognosis and can help to identify the candidates requiring transplantation.MRD2 positivity is not a contraindication for transplantation in pediatric patients,and early transplantation significantly improves the prognosis of high-risk patients.

Objective:To summarize the clinical features of reversible posterior encephalopathy syndrome(PRES)after allogeneic hematopoietic stem cell transplantation(allo-HSCT)in children.Methods:The clinical data of six children who developed PRES after undergoing allo-HSCT in the Department of Hematology of Wuhan Children's Hospital from June 2016 to December 2022 were retrospectively analyzed,and their clinical characteristics,imaging examination,laboratory examination,and treatment regression were summarized.Results:Among 281 children underwent allo-HSCT,6 cases(2.14％)developed PRES,with a median age of 5.1(1.5-9.7)years old.4 cases underwent related haploidentical donor transplantation,and 2 cases underwent sibling allografting and unrelated donor allografting donor transplantation,respectively.All six children had an acute onset of illness,with clinical manifestations of nausea and vomiting,seizures,psychiatric disorders,visual disturbances.The five cases elevated blood pressure.All children with PRES were treated with oral immunosuppressive drugs during seizures,and 3 cases were combined with different degrees of graft-versus-host disease.Most of the children showed effective improvement in clinical symptoms and imaging after adjusting/discontinuing suspected medications(cyclosporine,etc.)and symptomatic supportive treatments(oral antihypertensive,diazepam for antispasmodic,mannitol to lower cranial blood pressure),and one of them relapsed more than 8 months after the first seizure.Conclusion:PRES is rare after hematopoietic stem cell transplantation in children,and its onset may be related to hypertension,cytotoxic drugs,graft-versus-host disease,etc.Most of them can be recovered after active treatment,but not completely reversible,and the prognosis of those who combined with TMA is poor.

OBJECTIVE: To systematically evaluate obesity on the outcome of rotator cuff repair. METHODS: Literatures on the relationship between obesity and outcomes after rotator cuff repair were searched from PubMed, Embase, Cochrane Library, Web of Science, China biology medicine(CBM), CNKI, Wanfang and VIP databases from building database to August 1, 2022, and were screened independently by two authors according to inclusion and exclusion criteria. Endnote X9 and Excel 2019 were used for literature extraction, management and data entry, and Newcastle-Ottawa Scale (NOS) was used to evaluate quality of the included literatures. STATA 16.0 and RevMan 5.4 softwares were used to evaluate postoperative retear rate, reoperation rate, complication rate, American Shoulder and Elbow Surgeons (ASES) score, visual analogue scale (VAS), operative time and external rotation angle of shoulder joint pain were analyzed.

Objective: To examine the value of intravascular ultrasound (IVUS) for excimer laser ablation (ELA) combined with drug-coated balloon (DCB) in treating lower limb arteriosclerotic obliterans (ASO). Methods: As a prospective case series study, patients who underwent ELA combined with DCB for lower limb ASO with the guidance of IVUS from September 2021 to March 2022 at Department of Vascular Surgery, Zhongshan Hospital, Fudan University were enrolled prospectively. Lesion characteristics, procedure-related outcomes and complications were collected. The therapy outcomes were compared with baseline data by paired t test. Results: There were 8 males and 2 females, aged (72.0±5.9) years (range: 61 to 81 years). Of all the 11 lesions, there were 8 lesions in superficial femoral artery and 3 in popliteal artery. The lesion length was (7.0±2.4) cm (range: 3.2 to 9.8 cm). There were 4 chronic totally occlusion and 7 severe stenosis. All patients underwent the operation successfully. The technical success rate was 10/11. Bailout stenting was performed in one lesion because of flow-limiting dissection. Four lesions were grade 3 to 4 in peripheral artery calcium score system, and 9 lesions with calcification arc≥180°. Larger diameter drug-coated balloons were selected in 5 lesions after measurement of intravascular ultrasound. The follow-up time was (6.0±1.9) months (range: 3 to 9 months). The ankle-brachial index of the patient was significantly improved immediately after surgery (0.97±0.13 vs. 0.48±0.18, t=-7.60, P<0.01) and at 3 months after surgery (0.95±0.12 vs. 0.48±0.18, t=-7.17, P<0.01). The 3-month primary patency rate was 11/11, the target lesion reintervention was 0 and ulcer healing rate was 3/4. Conclusion: IVUS assisted ELA in the treatment of lower limb artery lesions is safe and effective in early stage.

Dysregulation of histone deacetylases (HDACs) is closely related to tumor development and progression. As promising anticancer targets, HDACs have gained a great deal of research interests and two decades of effort has led to the approval of five HDAC inhibitors (HDACis). However, currently traditional HDACis, although effective in approved indications, exhibit severe off-target toxicities and low sensitivities against solid tumors, which have urged the development of next-generation of HDACi. This review investigates the biological functions of HDACs, the roles of HDACs in oncogenesis, the structural features of different HDAC isoforms, isoform-selective inhibitors, combination therapies, multitarget agents and HDAC PROTACs. We hope these data could inspire readers with new ideas to develop novel HDACi with good isoform selectivity, efficient anticancer effect, attenuated adverse effect and reduced drug resistance.

AIM:To investigate the mechanism of curcumin inhibiting the choroidal neovascularization(CNV)of brown Norway(BN)rats.METHODS: CNV model of 36 BN rats was established through laser photocoagulation induction, and they were divided into 6 groups with 6 rats in each group. Normal group was fed normally with no intervention, while 532nm laser photocoagulation was used to establish a experimental CNV model in BN rats. Rats after modeling were respectively intervened for 14d and divided into model group, ranibizumab group, curcumin low [100mg/(kg·d)], medium [200mg/(kg·d)], and high [400mg/(kg·d)] dose group. The model group was given intragastric administration of saline for 14d, ranibizumab(10mg/mL, 0.2mL/dose)was injected at 2d after photocoagulation with 5μL once for rats in ranibizumab group, and different concentrations of curcumin were intragastrically administrated to the rats in low, medium and high groups for 14d. Fundus photography, fundus fluorescein angiography(FFA)and indocyanine green angiography(ICGA)examination were performed at 14d after photocoagulation. Ocular histopathological specimens of rats with CNV were made, and the central thickness of CNV were observed by HE staining. Ocular histopathological specimens were made, and the expressions of AKT/p-AKT/HIF-1α/VEGF signaling pathway-related proteins were observed by immunohistochemistry. The mRNA relative expressions of AKT/HIF-1α/VEGF factor in CNV tissues were detected by RT-qPCR, and the protein expressions of AKT/p-AKT/HIF-1α/VEGF factor in CNV tissues were detected by Western-blot.RESULTS: CNV generation rates in the model group, the ranibizumab group, and the low, medium and high-dose curcumin groups were 78.18%, 73.21%, 77.19%, 75.86%, 74.55%, respectively, which were higher than 70%. The average absorbance were 182.12±6.59, 119.22±8.03, 166.45±8.33, 164.34±5.69, 149.22±6.45, respectively; the ranibizumab group was significantly lower than the model group(P<0.05); the low-dose, medium-dose and high-dose groups were significantly higher than the ranibizumab group(P<0.05), and the curcumin high-dose group was significantly lower than the model group(P<0.05). HE staining showed that the retinal tissue structure of BN rats in normal group was clear and neatly arranged. The central thickness of CNV in the ranibizumab group was significantly reduced at 14d after photocoagulation compared with the model group(P<0.05); While the curcumin high-dose group was significantly reduced compared with the model group(P<0.05), but increased when compared with ranibizumab group(P<0.05). Immunohistochemistry results showed that AKT, p-AKT, HIF-1α, and VEGF factors were negatively expressed in the retinal tissue structure of BN rats in the normal group, and no brown-yellow reactants were found. The expression of AKT, p-AKT, HIF-1α, and VEGF factors in the model group were higher than that in the normal group at 14d after photocoagulation(P<0.05); the ranibizumab group was lower than the model group(P<0.05). While the expression of the curcumin high-dose group was significantly decreased compared with the model group(P<0.05), but significantly increased when compared with ranibizumab group(P<0.05). The mRNA results showed that the relative expression levels of AKT, HIF-1α and VEGF mRNA in the model group at 14d after photocoagulation were higher than those of the normal group(P<0.05); the ranibizumab group was lower than the model group(P<0.05). While curcumin high-dose group was significantly decreased compared with the model group(P<0.05), but significantly increased when compared with ranibizumab group(P<0.05). Western-blot results showed that there was no significant difference in the relative expression of AKT protein among each experimental groups at 14d after photocoagulation. The relative expression of p-AKT protein in the model group was significantly higher than that in the normal group(P<0.05); the ranibizumab group was significantly lower than the model group(P<0.05); the curcumin high-dose group was significantly lower than the model group(P<0.05). The relative expression levels of HIF-1α protein were significantly higher in the model group than in the normal group(P<0.05), and the ranibizumab group was lower than in the model group(P<0.05). The relative expression levels of HIF-1α protein was lower in the curcumin high-dose group than in the model group(P<0.05)but higher than ranibizumab group(P<0.05). The relative expression level of VEGF protein was significantly lower in the curcumin medium/high-dose group than in the model group(P<0.05).CONCLUSION: Curcumin at 400mg/(kg·d)has an inhibitory effect on CNV in BN rats. The mechanism may be closely related to inhibiting the activation of AKT/p-AKT/HIF-1α/VEGF signaling pathways.

Using the concepts and methods of epigenetics and metabolomics, to investigate the overall action molecular mechanism of Chrysanthemi indici C (CIC), the anti-hepatitis B virus (HBV) active extracts from Flos chrysanthemi indici. The inhibitory effects of CIC on proliferation and hepatitis B surface antigen (HBsAg), hepatitis B envelope antigen (HBeAg) and HBV-DNA of HepG2.2.15 cells were detected by CCK-8 and antigen kit. The DNA methyltransferases (DNMTs)/ten-eleven-translocation-2 (TET2) equilibrium was detected by ELISA. Illumina 850K methylation chip, pyrosequencing and qPCR were used to determine the action pathway and target of CIC by GO and KEGG analysis. Cell metabolites were extracted with 80% methanol, and the changes of differential metabolites, differential metabolic pathways and cell microenvironment were detected by LC-MS and other metabolomics methods. The results showed that CIC could inhibit the proliferation, HBsAg, HBeAg and HBV-DNA of HepG2.2.15 cells obviously, down-regulate DNA methyltransferase 1 (DNMT1), DNA methyltransferase 3a (DNMT3a) and DNA methyltransferase 3b (DNMT3b), up-regulate TET2, and restore the balance of DNMTs/TET2. The action targets of CIC were phospholipase C gamma 2 (PLCG2), phosphoinositide-3-kinase regulatory subunit 3 (PIK3R3), 1-acylglycerol-3-phosphate O-acyltransferase 2 (AGPAT2), 5-hydroxytryptamine receptor 2B (HTR2B), nerve growth factor (NGF), mainly involved in lipid metabolism, inflammation mediated regulation of transient receptor potential (TRP), phospholipase D signaling and advanced glycation end product-receptor for AGE (AGE-RAGE) signaling in diabetic complications pathways. CIC could significantly affect fatty acid metabolism and had great influence on phenolic acid, alkaloid and lipid metabolites in cell microenvironment. These results suggest that the action mechanism of CIC may be the synergistic action of multiple pathways and multiple targets, including related inflammatory pathways, immune pathways and lipid metabolism, through regulating epigenetic expression balance and restoring the balance of cell microenvironment.
