OBJECTIVETo study the function of pancreatic islet beta cells, insulin resistance (IR) and features of TCM symptoms and syndromes in the non-diabetic first-grade relatives (ND1GR) of patients with type 2 diabetes mellitus (DM2).
METHODSA total of 68 ND1GR of DM2 patients were enrolled in the observed group and 45 healthy subjects with matched sex, age and body mass index (BMI) but without family history of DM were selected into the control group. Levels of fasting blood glucose (FBG), 2 hrs postprandial glucose (2hPG), fasting insulin (FINS) and 2 hrs postprandial insulin (2h INS) in all the subjects were measured to calculate and compare the IR and beta-cell function of the homeostatic model analog (HOMA-IR and HOMA-beta), and the insulin sensitive index (ISI). Moreover, the symptoms manifested in the ND1GR were also observed to analyze the features in them.
RESULTSFBG and FINS were obviously higher in the observed group than those in the control group (P < 0.01), while no significant difference was found in 2hPG or 2h INS (P > 0.05). HOMA-IR and HOMA-beta were significantly higher (P < 0.05) and ISI were significantly lower (P < 0.01) in the observed group than those in the control group. Compared with the control group, the main symptoms such as dark purplish tongue, listlessness, thready and thin pulse, lassitude in loin and legs in the observed group were seen more frequently. In the observed group syndrome of deficiency of Qi and Yin accounted for 51.47%, syndrome of deficiency of Yin for 30.88%, subjects with syndrome of blood stasis as the main accompanying syndrome accounts for 61.76%.
CONCLUSIONHigher beta cell secretion function and lower insulin sensitivity appear in ND1GR of DM2 patients, suggesting the existence of insulin resistance. The feature of TCM syndrome in them is characterized by deficiency of Qi and Yin with inner obstruction of blood stasis.

To develop a Huntington’s disease(HD) cell model in vitro to screen drugs targeting the aggregation of polyQ,different length of CAG repeat fragments were amplified by random primer PCR, identified by DNA sequencing and were fused to the N-terminus of CAT in the pCAR system respectively which had been constructed and identified before. Recombinant plasmids were transformed into and induced to express in the host E.coli. SDS-PAGE and chloramphenicol resistance test were done to determine the solubility of the polyQ and chloramphenicol resistance levels of the fusions. With different length of CAG repeat fragments cloned and expressed in the CAT-fusion protein reporting system, it is found that when the length of the fragments increased over 40, their encoding polyQ expressed as insoluble protein and chloramphenicol resistance levels are lower, while under 40, the polyQ expressed as soluble ones and chloramphenicol resistance levels are higher. A in vitro HD model that could minimize the pathological process of the HD thus has been developed. With which by measure the recombinant bacteria’s resistance to chloramphenicol, the polyQ’ solubility and folding state in vitro by quality and quantity could be determined. Thus this model can be used to screen drugs or bioactivity materials that can inhibit aggregation of the polyQ, which thereby shedding new light on the prevent, diagnosis and therapy of HD.

OBJECTIVETo investigate the effects of 2 different ways of storage bag placement on some biochemical indexes of leukodepleted red blood cells (LD-RBC) to as to ensure the efficacy and safety of clinical blood transfusion.
METHODSThe whole blood samples of 20 donors (400 ml/donor) were selected for preparating the LP-RBC, which were divided evenly into 10 bags. The 10 bags were randomly divided into 2 groups; the bags in 1 group were placed uprightly, while the bags in another group were placed horizontally. The bags of 2 groups were stored in the same conditions. One storage bag from each group was taken randomly on day 7, 14, 21, 28, 35 respectively, and then the biochemical indexes of samples were detected and analyzed.
RESULTSThe values of K(+) and LAC on day 14, the value of LDH on day 28 in the uprightly placed group were higher than those in the horizontally placed group (P < 0.05), the value of Na(+) on day 28, and the value of Glu on day 35 in the uprightly placed group were lower than those in horizontally placed group (P < 0.05), but there was no significant difference in Cl(-) level between 2 groups (P > 0.05).
CONCLUSIONThe storage bags placed by different ways during the storage show different influence on some biochemical indexes of LD-RBC in the storage period.

This study was aimed to compare the expressions of specific transcription factors of CD4(+) T cell subset ( T-bet, GATA-3, RORγt and FoxP3 mRNA) in peripheral blood of patients with aplastic anemia(AA), myelodysplastic syndrome(MDS), and acute myeloid leukemia(AML), and investigate their immune status and pathogenesis, so as to provide experimental basis for the choice of clinical treatment. The expression of T-box (T-bet), GATA-3, ROR-γt and Foxp3 mRNA in PBMNC were examined by RT-PCR in 42 cases of MDS, including 22 refractory anemia(MDS-RA) and 20 refractory anemia with excess blasts (MDS-RAEB), in 23 cases of AA, 17 cases of AML patients and 16 healthy volunteers respectively. The results indicated that, compared with normal control group, expressions of T-bet and RORγt mRNA in AA patient group were significantly higher (P < 0.01), expression levels of GATA3 Foxp3 mRNA were lower (both P < 0.01). There was no significant difference in expression of T-bet and GATA3 mRNA between MDS group and normal control group, but the expression levels of Foxp3 and RORγt mRNA were higher than those in normal controls (P < 0.05); T-bet and RORγt in MDS-RA group were higher than those in the normal controls(P < 0.01), and GATA3 expression significantly reduced (P < 0.05), however, there was no significant difference in expression of Foxp3 between MDS-RA and the controls. Expression levels of T-bet and RORγt mRNA in patients with MDS-RAEB and AML were lower than those in normal controls (P < 0.05), but the expression levels of GATA3 and Foxp3 mRNA were significantly higher than those in normal controls (P < 0.01). It is concluded that the transcription factor expressions are different in PBMNC of patients among these three diseases. Immune-mediated excessive apoptosis may play an important role in pathogenesis, bone marrow failure in patients with AA and MDS-RA, and abnormal clones of immature cells may be one of main reasons for bone marrow failure in AML and late stage of MDS.

Myelodysplastic syndrome (MDS) are a heterogeneous group of hematological malignancies. Currently, in addition to demethylated chemotherapy and hematopoietic stem cell transplantation, MDS patient-derived mesenchymal stem cells (MDS-MSC) play an important role in understanding the pathogenesis of MDS and related therapeutic targets. For example, abnormal expression of DICER1 gene, abnormalities of PI3K/AKT and Wnt/β-catenin signaling pathways provide new therapeutic targets for MDS. In addition, MDS-MSC is also affected by abnormal microenvironment of the body, such as inflammatory factor S100A9, as well as hypercoagulation and iron overload. In this review, genes, signaling pathways, cytokines, hematopoietic microenvironment, and the effect of therapeutic drugs for MDS-MSC were briefly summarized.

Multiple myeloma (MM) is a malignant proliferative disease of plasma cells. Bone marrow mesenchymal stem cells (MSC) play an important role in the progression of MM. Compared with normal donor derived MSC (ND-MSC), MM patients derived MSC (MM-MSC) exhibit abnormalities in genes, signaling pathways, protein expression levels and cytokines secreted by themselves. Moreover, the exosomes of MM-MSC can interact with the bone marrow microenvironment. The above reasons can lead to MM cell proliferation, chemoresistance, impaired osteogenic differentiation of MM-MSC, and affect the immunomodulatory capacity of MM patients. In order to further understand the pathogenesis and related influencing factors of MM, this paper reviews the latest research progress of MM-MSC.
