Objective To assess the relationship between pulse wave velocity(PWV) and carotid atherosclerosis by UltraFast imaging.Methods 476 cases from Medical Examination Center of Beijing Friendship Hospital were enrolled in this study.According to intima-media thickness(IMT) of carotid artery,all subjects were divided into two groups:IMT without thickening group (G0) of 283 cases and IMT thickening group (G1) of 193 cases.Through UltraFast imaging,carotid artery PWV was measured,including the PWV at the beginning of the systole(BS) and the PWV at the ending of the systole(ES).Carotid IMT and plaque situation were recorded under gray-scale ultrasound.BS and ES were compared between the two groups.Spearman rank correlation was used to analyse the correlation between IMT of carotid artery and BS,between IMT of carotid artery and ES.Two independent samples t test to compare BS,ES between the two groups.Results BS of G1 and G0 were (6.03 ± 1.33)m/s and (5.51 ± 1.13)m/s,t =-4.571,P =0.000;ES of G1 and G0 were (8.42 ± 2.13)m/s and (7.34 ± 2.02) m/s,t =5.619,P =0.000.BS and ES of G1 were larger those of G0 respectively.BS (r =0.192,P =0.000) and ES (r =0.249,P =0.000) were correlated with the IMT of carotid artery.Conclusions Ultrafast imaging technique can quickly measure the carotid artery PWV.BS and ES of carotid artery can be quick,convenient,safe,noninvasive parameters for evaluating carotid atherosclerosis.

[ Objective] To discuss the characteristics of death among elderly people aged 60 years and above in Shanghai, who were classified into different age groups, and to provide a basis for making public health policy. [ Methods] On the basis of the data covering whole population death registry system in Shanghai, data on the elders aged 60-plus was collected and classified into 3 age groups according to WHO standards for descriptive analysis. [ Results] The crude death rate among the elders aged 60-plus in shanghai in 2014 was 3 001.76/105 ,accounting for 88.37%of the total mortality.The crude death rate of male was higher than that of female in each age group.The main causes of death in 60-74 age-group were cancer and coronary heart disease ( CHD) which had shorter course of disease with worse prognosis. The main causes of death in 75-89 age-group were cardiovascular and cerebrovascular diseases and chronic obstructive pulmonary disease ( COPD) which had longer course.The main causes of death in 90-pluse group included functional degradation and accidental fall, apart from cardiovascular and cerebrovascular diseases and COPD.And 54.35%of the elders aged 60-plus died in hospital, while 34.12%at home,and 6.63%at nursing home.The proportion of death at home was higher in non-central urban area than in central urban area.And the proportion of death in hospital decreased with increasing age. [ Conclusion] The proportion of the elderly death was large in total mortality.As the characteristics of death varied in different age groups, government should adopt different prevention and control measures.Rational allocation of medical and rehabilitation resources, as well as terminal care, need more attention and exploration by all institutions concerned.

This study was aimed to establish the technique of interphase fluorescence in situ hybridization (I-FISH) used on smear of bone marrow directly, and to develop a new method for detection of the molecular cytogenetics in multiple myeloma (MM). After a series of treatment, fixation and digestion of the bone marrow smear as the carrier, the chromosome 8 centromere probe were used in I-FISH for molecular cytogenetics detection. At the same time, differences were compared in the results between the new method and the conventional I-FISH. The results showed that there was no statistically significant difference of proportion of various signals in non-hematologic malignancies when detected with the two methods (p>0.05). In bone marrow smear I-FISH, 8 out of 19 cases (42.1%) had abnormality of chromosome 8, including 5 cases with -8 (26.3%) and 3 cases with +8 (15.8%). It is concluded that the I-FISH on smear of bone marrow is characterized by convenience, economy and accuracy. Therefore, it can be used for research of molecular cytogenetics in MM.

BACKGROUNDThe association between IGF2BP2 and type 2 diabetes mellitus (T2DM) has been repeatedly confirmed among different ethnic populations. However, in several genome-wide association studies (GWAS) from the Chinese Han population, the gene IGF2BP2 has not been replicated. The results of relevant studies for the association between IGF2BP2 and T2DM showed controversy in Chinese Han population. It is necessary to systematically evaluate the contribution of common variants in IGF2BP2 to T2DM in Chinese Han population.

METHODSTwo single-nucleotide polymorphisms (SNPs, rs4402960 and rs1470579) in IGF2BP2 were genotyped in Chinese Han population (3807 controls/4531 T2DM cases) by Illumina GoldenGate Indexing assay. The association between SNPs and T2DM was evaluated by multiple Logistic Regression analysis. A meta-analysis was used to estimate the effects of IGF2BP2 in 20854 Chinese Han individuals.

RESULTSrs1470579 and rs4402960 were confirmed to have strong association with T2DM in the Chinese Han population (rs1470579 P = 1.80×10(-7), OR (95% CI) = 1.22 (1.14-1.32), rs4402960 P = 7.46×10(-9), OR (95% CI) = 1.26 (1.17-1.37), respectively). Moreover, 11 studies for rs4402960 were included in the meta-analysis and 7 studies for rs1470579. The meta-analysis also showed the association between T2DM and IGF2BP2 (rs1470579 OR of 1.15 (95% CI = 1.10-1.19), P < 0.0001 under an additive model and rs4402960 OR of 1.14 (95% CI = 1.10-1.18), P < 0.0001 under an additive model).

CONCLUSIONIGF2BP2 was strongly associated with the risk of T2DM in Chinese Han population.

The purpose of this study was to compare the efficacy of CEP plus G-CSF and CVP plus G-CSF regimens in the mobilization and collection of peripheral blood hematopoietic stem cells (PBHSC), and in the hematopoietic recovery. 57 patients with non-Hodgkin's lymphoma (NHL) underwent autologous PBHSC transplantation were analyzed retrospectively. The PBHSC were mobilized and collected by using CEP plus G-CSF and CVP plus G-CSF respectively, and were retransfused into these NHL patients after preconditioning, then the mobilization efficacy, adverse reactions and hematopoietic recovery were analyzed. The results showed that the WBC count decreased to ≤ 1.0 × 10(9)/L, platelet amount dropped to ≤ 40 × 10(9)/L during peripheral blood stem cell mobilization of all patients, which indicated successful collection of PBHSC. The mean value of (4.38 ± 3.40) × 10(8)/kg mononuclear cells (MNC) containing (2.79 ± 2.53) × 10(6)/kg CD34(+) cells were collected in CEP plus G-CSF group, while the mean value of (3.31 ± 1.23) × 10(8)/kg MNC containing (2.02 ± 0.87) × 10(6)/kg CD34(+) cells were collected in CVP plus G-CSF group. The efficacy of mobilization in CEP plus G-CSF group was significantly higher than that in CVP plus G-CSF group (p < 0.05). After preconditioning, bone marrow was suppressed in all patients. The average time of WBC count recovery to ≥ 1.0 × 10(9)/L was 11.4 days in CEP plus G-CSF group and 12.3 days in CVP plus G-CSF group; the average time of platelet amount recovery to ≥ 50 × 10(9)/L was 18.6 days in CEP plus G-CSF group and 19.3 days in CVP plus G-CSF group. The statistical analysis showed no significant difference in the average time of hematopoietic recovery between 2 groups. It is concluded that autologous PBHSC transplantation shows significant effect for treatment of patients with NHL. Either modified CEP or CVP plus G-CSF regimen is safe and effective in PBHSC mobilization. The CEP plus G-CSF regimen is better than CVP plus G-CSF regimen.

To study the protective effects of Wuzi Yanzong recipe on DNA oxidative damage of testis germ cells in natural ageing rats based on Nrf2/HO-1 signaling pathway and base excision repair (BER). In the study, 16-month-old SPF grade male SD rats were randomly divided into three groups, namely ageing model group, and low and high-dose Wuzi Yanzong recipe groups (WZ, 1, 4 g·kg⁻¹). In addition, 2-month-old SD rats were used as adult control group (10 rats in each group). The ageing model group and the adult control group were fed with normal diet for 4 months. WZ groups were given medicated feed for 4 months. After fasting for 12 hours, the rats were put to death. Then, the testes were immediately removed. The vitality of superoxide dismutase (SOD) and malondialdehyde (MDA) content in testis were detected by xanthine oxidase method and thiobarbituric acid (TBA) method. The levels of Nrf2 and 8-OHdG were detected by immunofluorescence. The protein expression levels of Nrf2, HO-1, NQO1, APE1, OGG1 and XRCC1 were detected by Western blot. Compared with the ageing model group, WZ significantly increased the SOD vitality and decreased MDA content of testis. In addition, immunofluorescence results showed that WZ significantly attenuated testicular DNA oxidative damage and improved antioxidant capacity. Such changes were accompanied by the down-regulation of DNA oxidative damage response protein 8-OHdG levels and the up-regulation of Nrf2 levels. Moreover, Western blot results showed that WZ significantly increased the protein expression levels of Nrf2, HO-1 and NQO1 of the testis germ cells, when compared with ageing model group. In parallel, the protein expression levels of APE1, OGG1 and XRCC1 were significantly decreased. In conclusion, WZ improves ageing-related DNA oxidative damage via Nrf2/HO-1 and BER pathways.

To study the protective effects of Wuzi Yanzong recipe on testis germ cell apoptosis in natural ageing rats through endoplasmic reticulum stress (ERS), 16-month-old male SPF grade SD rats were randomly divided into three groups: ageing model group, and low and high-dose Wuzi Yanzong recipe groups (WZ, 1 and 4 g·kg⁻¹), with 10 rats in each group. In addition, 2-month-old SD male rats were used as adult control group. The ageing model group and the adult control group were fed with normal diet for 4 months. WZ groups were given the medicated feed for 4 months. After fasting for 12 hours, the rats were put to death. Then, the testes were immediately collected. The change of testicular tissue morphology was observed by HE staining. The expression levels of ER stress-related proteins GRP78, p-PERK, p-eif2, ATF4, p-IRE1, XBP1, ATF6 and apoptosis-related proteins CHOP, caspase12 and p-JNK in testes were detected by Western blot. Compared with the ageing model group, Wuzi Yanzong recipe alleviated the morphological changes of testicular tissue. Western blot results showed that Wuzi Yanzong recipe significantly increased the expression levels of endoplasmic reticulum stress-related proteins GRP78, p-PERK, p-eif2, ATF4, p-IRE1, XBP1, ATF6 and significantly decreased the expression levels of endoplasmic reticulum-induced apoptosis-related proteins CHOP, caspase 12 and p-JNK. In conclusion, Wuzi Yanzong recipe can alleviate the ageing-related apoptosis of testicular germ cells in natural ageing rats by regulating endoplasmic reticulum stress.
