Objective To investigate the efficacy of HLA-matched ABO-incompatible sibling al- logeneic peripheral blood stern cell transplantation(allo-PBSCT)in treatment of hematologic malig- nancies.Methods Between June 2001 and September 2005,68 patients with hematologic malignancies received allo-PBSCT from HLA-identical sibling donors.Among them,38 were ABO-compatible (ABO-compatible group),30 ABO-incompatible(ABO-incompatible group).Conditioning regimen of all patients:BU/CY used as conditioning regimen in AML,MDS and CML patients;TBI/CY used in ALL and NHL patients.TBI/CY/Melphan used in MM patients.GVHD prophylaxis:A combination of cyclosporine(CsA)and mycophenolate mofetil(MMF)and methotrexate(MTX)was administered for GVHD prophylaxis.Results (1)Sixty-seven patients were all engrafted,and only one patient was graft failure.The median time(range)to neutrophils≥0.5?10~9/L and platelets≥20?10~9/L was +12(+9~+15)and+21(+15~+40)days post-transplant respectively.The time to neutrophil and platelet engraftment had no significant difference between ABO-incompatible group and ABO-com- patible group(P>0.05);(2)Thirty patients with ABO-incompatible allo-PBSCT had no evidence of hemolysis.In ABO-incompatible group,the onset of erythropoiesis after allo-PBSCT was delayed. Three of 7 patients with blood group“O”receiving a group“A”developed pure red cell aplasia (PRCA).The blood type of 30 patients would transfer to the type of donors in 60 days(24~153 days)after transplantation.(3)Following up to 30th,Sep.2005,the incidence of aGVHD was high- er in ABO-incompatible group(20.0%)than that in ABO-compatible group(2.6%,P=0.019). The incidence of cGVHD,VOD,HC,CMV infection,disease relapsed rates and mortality had no sig- nificant difference between ABO-incompatible and ABO-compatible recipients(P>0.05).(4)Kaplan- Meier survival analysis revealed the rates of survival had no significant difference between ABO-incom- patible and ABO-compatible recipients(P>0.05).Conclusions ABO-incompatible allo-PBSCT is fairly safe if there is indication.Although the incidence of aGVHD was higher in ABO-incompatible group than that in ABO-compatible group,but there was no effect on engraftment,incidence of cGVHD or prognosis.

Our previous study demonstrates that hypoxia promotes human bone marrow-derived mesenchymal stem cell (hMSC) proliferation. The aim of the present study was to investigate the gene profile involved in this process by using cDNA microarray. Cultured hMSCs were treated with hypoxia (3% O(2)) for 4 h, 12 h, 24 h, 36 h, 48 h and 72 h, respectively. Then these cells were collected to prepare total RNA. Hypoxia-induced gene expression profile was examined and analyzed by GenePix Pro 4.0 software. Some of cDNA microarray results were confirmed by RT-PCR. Microarray analysis identified that 282 genes expressed differentially, of which most were involved in metabolism. The number of differentially expressed genes at different hypoxia time points was different, and most genes were regulated after 24-hour hypoxia. Among the 282 differentially expressed genes, 4 hypoxia-inducible factor 1 (HIF-1) targeted genes and 10 genes that changed at 3 continuous time points were found. The results obtained indicated that 4 HIF-1 targeted genes, i.e., transforming growth factor beta3 (TGFbeta3), phospho-glycerate kinase 1 (PGK1), insulin-like growth factor binding protein 3 (IGFBP3) and BCL2/adenovirus E1B 19 kDa interacting protein 3 (BNIP3), displayed up-regulated pattern at 36 h under hypoxia. BNIP3 displayed a dynamically up-regulated pattern at 12, 36 and 72 h under hypoxia. However, TGFbeta3 and PGK1 were down-regulated at 72 h. In addition, the gene expressions of adenylate kinase 3-like 1 (HAC), neurofilament light polypeptide 68 kDa (NEFL), N-myc downstream regultated gene 1 (NDRG1), discoidin domain receptor family member 1 (DDR1), tribbles homolog 3 (TRIB3), nucleoprotein (AHNAK) and eukaryotic elongation factor selenocyteine-tRNA-specific (EESTS) were up-regulated. Moreover, the gene expressions of EESTS, NEFL were up-regulated at 5 different time points under hypoxia. Furthermore, it was found that the gene expressions of histone cluster 1 (HIS1) and transferring receptor (TFRC) were down-regulated. These results suggest that the proliferation of hMSCs induced by hypoxia is a complex process in which a number of genes may be involved.

In the context of the new era, paying attention to maternal and child health and advocating prenatal and postnatal care can effectively improve the quality of the birth population. Traditional Chinese medicine has a long history of prenatal and postnatal healthcare with rich content, which is the theoretical basis of modern related services. With the social development and the improvement of people's awareness of prenatal and postnatal healthcare, people have gradually shifted the focus of prenatal and postnatal healthcare to the peri-pregnancy stage at present, namely that couples of childbearing age are guided to prepare for pregnancy under the premise of solving their basic diseases. Infertility is a common and refractory disease for women of childbearing age. Ovulation disorder is one of its common pathological mechanisms. Traditional Chinese medicine believes that kidney deficiency is the main cause and pa-thogenesis of anovulation infertility and blood stasis is an important factor throughout the disease course. In clinical practice, therapies for invigorating kidney and activating blood are safe and reliable to treat anovulatory infertility mainly by adjusting the hypothalamus-pituitary-ovarian axis, improving ovarian function, uterine environment and gamete quality and increasing endometrial volume. Under the guidance of the thought of prenatal and postnatal healthcare, the authors tried to explore the effect of therapies for kidney-tonifying and blood-activating in the treatment of anovulatory infertility in eugenics, with the purpose of providing ideas and basis for subsequent relevant clinical studies and contributing to prenatal and postnatal healthcare services.

This study used network pharmacology and molecular docking to study the mechanism of Bushen Culuan Formula in the treatment of infertility caused by polycystic ovary syndrome(PCOS). The active ingredients and potential drug targets of Bushen Cu-luan Decoction were obtained by searching the Traditional Chinese Medicine System Pharmacology(TCMSP) database, and the targets of PCOS by searching GeneCards. After the drug targets and disease targets were corrected by Uniprot, the intersection genes were obtained. STRING database and Cytoscape 3.7.2 were used for protein-protein interaction(PPI) analysis of the intersection genes. The ClueGO plug-in of Cytoscape 3.7.2 was employed to perform gene ontology(GO) enrichment and KEGG pathway enrichment for the intersection genes. Finally, molecular docking of the key active ingredients with the targets of Bushen Culuan Formula was performed using AutoDockVina and MGLtools. A total of 136 active ingredients and 314 drug targets of the decoction were obtained from TCMSP, and 136 disease targets from GeneCards. Finally, 49 drug-disease intersection genes were obtained. GO enrichment found that the genes were mainly involved in the regulation of muscle cell apoptosis, positive regulation of small molecule metabolism, core promoter binding, RNA polymerase Ⅱ regulation of pri-miRNA transcription, negative regulation of transmembrane transport and other biological functions. The enriched KEGG pathways mainly included MAPK, PI3 K-Akt, p53, and HIF-1 signaling pathways. The results of molecular docking showed that quercetin and PTGS2 can bind stably and interact through amino acid residues THR206, TRP387, ASN382, etc. This study preliminarily reveals the multi-component, multi-target, and multi-pathway mechanism of Bushen Culuan Formula in the treatment of PCOS-related infertility, which provides a basis for further research.

To establish a mouse model of premature ovarian insufficiency( POI) with kidney deficiency and blood stasis pattern by Tripterygium wilfordii polyglycoside( TWP) gavage,and to evaluate the ovarian function and fertility of the model,in order to find Bushen Culuan Decoction therapeutic mechanism. 60 SPF level Blab/c female mice with normal estrous cycle were randomly divided into 6 groups of 10 each: blank group 1( BG1),blank group 2( BG2),blank fertility group( BFG),model group( MG),model recovery group( MRG) and model fertility group( MFG). The mice in three model groups were treated by gastric gavage with TWP suspension 40 mg·kg-1 twice a day for 14 days,while the mice in three blank groups were treated by gastric gavage with same volume normal saline for 14 days. The mice in BG1 and MG were sacrificed and dissected on day 15. The mice in BG2,BFG,MRG and MFG were returned normal feeding from day 15 and were sacrificed and dissected on day 29. The mice in BFG and MFG were cohabited with male mice with a ratio of 2 ∶1( female ∶male) from day 15. The general situation and estrous cycles of all mice were observed every day. Serum sex hormone levels,ovarian index,uterine index,ovarian morphology,follicle count,ovarian VEGF and ES index were observed within the mice in BG1,BG2,MG and MRG. Pregnancy rate,litter size,survival number of newborn mice and male-female proportion were reported within the mice in BFG and MFG. In model establishing stage,the body weight of mice significantly decreased( P <0. 05) in MG and MFG. Compared with BG1,the mice in model group had irregular estrous cycle,decreased ovarian and uterine indexes,less primordial and developing follicles,more atretic follicles,increased VEGF expression and decreased ES expression( P <0. 05). Compared with blank group 2,the mice in model recovery group had irregular estrous cycle,increased FSH level,decreased ovarian indexes,less primordial and developing follicles,more atretic follicles,increased VEGF expression( P<0. 05). Compared with blank fertility group,the mice in model fertility group had smaller litter size and newborn mice survival count( P<0. 05). Gastric gavage with TWP 40 mg·kg-1 twice a day for 14 days is a feasible way to establish a POI kidney deficiency and blood stasis pattern mouse model. The mice ovarian functions didn't recovery on day 14 after stopping TWP intervening,which could suggest the effectiveness of subsequent therapeutic intervention.

OBJECTIVE To explore the effects of the expression of serum Sirtuin-1 (SIRT1) on therapeutic efficacy of sodium valproate (VPA) in the treatment of epilepsy patients. METHODS Fifty-four epileptic patients were collected from the Affiliated Baiyun Hospital of Guizhou Medical University from Mar. to Oct. 2021 as the research objects, and fifty healthy people were also collected during corresponding period as baseline reference samples. The patients whose relative mRNA expression of SIRT1 was lower than the baseline were selected as SIRT1 low-expression treatment group, and the patients whose that expression was higher than the baseline as SIRT1 high-expression treatment group.All patients were treated with low dose (12 mg/kg or about 600 mg/day) of VPA for 3 months, and the clinical efficacy was evaluated. The dosage of VPA in patients with ineffective gzwkj2021-468) epilepsy control should be increased to 15 mg/kg or about 800 mg/day for another 3 months as SIRT1 high-expression intensive treatment group and SIRT1 low-expression intensive treatment group. Clinical efficacies were evaluated. The blood concentration and liver function indexes of the patients were detected after 3 months of treatment and 3 months of intensive treatment. RESULTS Before treatment, among 54 epileptic patients, 31 epileptic patients had low expression of SIRT1, and 23 had high expression of SIRT1. After 3 months of low-dose VPA treatment, within effective blood concentration of VPA, effective control rate of patients in SIRT1 high-expression treatment group was significantly lower than SIRT1 low-expression treatment group (P<0.05). After 3 months of intensive treatment, the effective control rate of patients SIRT1 high-expression intensive treatment group was significantly higher than SIRT1 high expression treatment group (P<0.05). No abnormality was found in liver function indexes during VPA treatment. CONCLUSIONS Epilepsy in patients with high expression of serum SIRT1 may be more difficult to control when VPA is within the effective blood concentration range; when the VPA dose is effectively increased, the effective control rate of epilepsy can be improved.

Protein complexes are involved in the synthesis of multiple secondary metabolites in plants, and their separation is essential to elucidate plant secondary metabolism and improve in vitro catalytic efficiency. In this study, the transgenic hairy roots of CYP76AH1, a key enzyme of tanshinone synthesis pathway, was constructed and the transgenic hairy roots of Danshen overexpressing CYP76AH1 protein were screened by Western blotting and used as a tissue culture material for the subsequent extraction of protein complex in tanshinone synthesis pathway. By optimizing the type and concentration of the detergent in the protein extraction buffer, the buffer containing 0.5% Triton X-100 was selected as the best extraction buffer, and a relatively large amount of soluble CYP76AH1 protein was isolated. This study lays the foundation for the further separation and purification of protein complexes interacting with CYP76AH1, and provides the idea for deep analysis of tanshinone metabolic pathway.
