Objective To evaluate the immune function and the degree of bone marrow suppression of ubenimex tablets on the treatment of patients with triple-negative breast cancer underwent chemotherapy.Methods108 cases in Jiaxing hospital of traditional Chinese medicine were randomly divided into the control group and the experimental group, 54 cases in each group.The two group were all treated with AC-T chemotherapy (pirarubicin+ cyclophosphamide + docetaxel).At this basis, the experimental group were given ubenimex.Flow cytometry was used to detect the changes of T lymphocyte subsets, natural killer cell (NK cell) immune function and peripheral blood cell parameters in the two groups before and after the treatment and 6 months after the treatment.ResultsCompared to the control group, the T lymphocyte subsets and NK cell changes in the experimental group before and after chemotherapy were significantly smaller (P<0.05).The T lymphocyte subsets and NK cells in the experimental group were more accurate than those in the control group (P<0.05).The peripheral blood cells in the experimental group were significantly smaller than those in the control group (P<0.05).Compared with the control group, the whole blood cells increased significantly in the experimental group 6 months after chemotherapy(P<0.05).ConclusionIt can help to reduce the effect of chemotherapeutic drugs on the immune function and bone marrow suppression which ubenimex tablets was used on the treatment patients with triple-negative breast cancer c.Patients can be successfully complete the chemotherapy process, and the long-term and short-term adverse reactions were less, prognosis is good, clinical promotion value is significant.

Objective To evaluate the association between vitamin D deficiency and diabetic nephropathy in type 2 diabetic patients.Methods A total of 594 patients with type 2 diabetes were enrolled from the inpatients of the Nanjing Medical University Affiliated Nanjing Hospital.Fasting serum lipid profile,25-hydroxycalciferol vitamin D and urinary albumin excretion rate were investigated.The relationship between nephropathy and vitamin D deficiency (＜ 20 μg/L) or insufficiency (20-＜ 30 μg/L) was analyzed.Results Nephropathy was found in 177 subjects (29.8％) with albuminuria in 141 and proteinuria in 36 subjects.Vitamin D deficiency was found in 180 subjects and insufficiency in 157 subjects.The proportion of vitamin D deficiency was higher in the individuals with nephropathy than those without nephropathy (36.2％ vs 27.8％,P ＜0.05).The urinary albumin excretion rate was significantly higher in the patients with vitamin D deficiency than those with normal vitamin D concentration [(123.0 ± 299.2)mg/24h vs (47.6 ±97.1) mg/24h,P ＜0.01].The prevalence of nephropathy was higher in the patientswith vitamin D deficiency than those with normal vitamin D concentration (35.6％ vs 26.1％,P ＜ 0.05),while the prevalence of proteinuria was higher in patients with vitamin D deficency (12.2％ vs 3.1％,P ＜0.01).Logistic regression analysis demonstrated that vitamin D deficiency was associated with nephropathy (OR 1.57,95％ CI 1.04-2.37),even after the adjustment for age,gender,hypertension,dyslipidemia,smoking status,use of angiotensin-converting enzyme inhibitors or angiotensin receptor blockers (OR 1.78,95％ CI 1.12-2.81).The Vitamin D concentration was significantly negatively correlated with urinaryalbumin excretion rate (r =-1.783,P ＜ 0.001).Conclusions Type 2 diabetic patients have a high prevalence of vitamin D deficiency.Vitamin D deficiency is independently associated with diabetic nephropathy.

Objective To explore the value of microvascular angiography in evaluating the neovascularization of internal carotid artery plaque and the prediction of cerebral infarction.Methods A total of 100 patients with suspected cerebral infarction received from March 19th,2016 to December 1 st,2017 in our hospital were enrolled in this study.All patients underwent microvascular imaging and then analyzed the importance of this technique in evaluating cerebral infarction,plaque neovascularization.Results 100 lesions were recorded in 100 patients,among which there were 22 cases with no superb microvascular ultrasound imaging (SMI) and blood flow signal (ie,score 0) in the plaque.SMI imaging could better show neovascularization (ie score 1 or 2 points).In 78 cases,they all grew from the arterial wall to the plaque.There were 61 cases of cerebral infarction in the blood flow group (78.2％),8 cases (36.3％) of cerebral infarction in the group without blood flow,with statistical significance(P =0.023).SMI imaging was highly sensitive to the prediction of cerebral infarction incidence,reaching 88.4％.Conclusions Ultra-microvascular imaging can improve the sensitivity of cerebral infarction prediction and promptly detect neovascularization of internal carotid artery plaque,thus providing a basis for clinical treatment.

OBJECTIVETo enrich our national database with data of rare diseases by analyzing molecular diagnosis and hematopoietic stem cell transplantation (HSCT) in children with inherited bone marrow failure syndromes (IBMFS).

METHODNext-generation sequencing (NGS)-based genetic diagnosis panel was applied for the clinical diagnosis and management of IBMFS. Retrospective analysis was performed on clinical and genetic data of 17 consecutive children who received HSCT over a long time interval (November. 2005-June 2015).

RESULTThree patients were diagnosed only by clinical manifestation before 2012. After that NGS-based genetic diagnosis panel was used to identify IBMFS-related genes in 12/14.IBMFS patients (except two Diamond-Blackfan anemia (DBA) patients). Two Fanconi anemia (FA) patients were confirmed to be new variations through family-genotype-analysis and 3 families accepted prenatal diagnosis to avoid birth of affected fetuses. Seventeen IBMFS patients (10 FA,5 DBA and 2 dyskeratosis congenital (DKC)) were treated with HSCT from matched sibling donors (n=2), matched unrelated donors (n=8) or mismatched unrelated donors (n=7). The source of stem cells for transplantation included peripheral blood (n=12) and cord blood (n=5). With regard to the conditioning regimens, FA and DKC patients received fludarabine-based reduced intensity conditioning, while DBA patients received classical busulfan-based myeloablative conditioning. Median age at the time of HSCT was 36 months (7-156 months). The number of infused mononuclear cells and CD34⁺ cells was (10.6 ± 6.7) × 10⁸ and (5.9 ± 7.0) × 10⁶ per kilogram of recipient body weight, respectively. The median number of days to neutrophil recovery was 13 days after HSCT (range: 10-19 days). Platelet recovery was faster in the PBSCT group than in the CBT group ((16.3 ± 6.0) days vs. (30.0 ± 17.1) days,t=-2.487,P=0.026). During a median follow-up of 17 months (range: 2-114 months), except one FA patient who was transplanted with HLA-matched unrelated cord blood (CB) died from pneumonia and heart failure because of engraftment failure, other 16 children are alive after the successful HSCT. The failure-free survival rate of the patients three years after HSCT was 94%.

CONCLUSIONNGS-based molecular diagnosis technology and effective HSCT have significantly facilitated the treatment of children with IBMFS in our country, and our national database about this rare disease is to be further exploited.
