OBJECTIVE: To estimate the univariate heritability of resting heart rate and common chronic disease such as hypertension, diabetes, and dyslipidemia based on extended pedigrees in Fujian Tulou area and to explore bivariate heritability to test for the genetic correlation between resting heart rate and other relative phenotypes. METHODS: The study was conducted in Tulou area of Nanjing County, Fujian Province from August 2015 to December 2017. The participants were residents with Zhang surname and their relatives from Taxia Village, Qujiang Village, and Nanou Village or residents with Chen surname and their relatives from Caoban Village, Tumei Village, and Beiling Village. The baseline survey recruited 1 563 family members from 452 extended pedigrees. The pedigree reconstruction was based on the family information registration and the genealogy booklet. Univariate and bivariate heritability was estimated using variance component models for continuous variables, and susceptibility-threshold model for binary variables. RESULTS: The pedigree reconstruction identified 1 seven-generation pedigree, 2 five-generation pedigrees, 23 four-generation pedigrees, 186 three-generation pedigrees, and 240 two-generation pedigrees. The mean age of the participants was 57.2 years and the males accounted for 39.4%. The prevalence of hypertension, diabetes, dyslipidemia in this population was 49.2%, 10.0%, and 45.2%, respectively. The univariate heritability estimation of resting heart rate, hypertension, and dyslipidemia was 0.263 (95%CI: 0.120－0.407), 0.404 (95%CI: 0.135－0.673), and 0.799 (95%CI: 0.590－1), respectively. The heritability of systolic blood pressure, diastolic blood pressure, fasting glucose, total cholesterol, triglyceride, high-density lipoprotein cholesterol, and low-density lipoprotein cholesterol was 0.379, 0.306, 0.393, 0.452, 0.568, 0.852, and 0.387, respectively. In bivariate analysis, there were phenotypic correlations between resting heart rate with hypertension, diabetes, diastolic blood pressure, fasting glucose, and triglyceride. After taking resting heart rate into account, there were strong genetic correlations between resting heart rate with fasting glucose (genetic correlation 0.485, 95%CI: 0.120－1, P<0.05) and diabetes (genetic correlation 0.795, 95%CI: 0.181－0.788, P<0.05). CONCLUSION Resting heart rate was a heritable trait and correlated with several common chronic diseases and related traits. There was strong genetic correlation between resting heart rate with fasting glucose and diabetes, suggesting that they may share common genetic risk factors.

BACKGROUND: Bone marrow mesenchymal stem cells (BMSCs) and BMSCs-derived exosomes have similar functions, but the regulatory mechanism underlying the release of exosomes is still unclear. OBJECTIVE: To investigate the role of GW4869, an inhibition of neutral sphingomyelinase 2, in the release of exosomes in BMSCs and the influence of GW4869 on BMSCs proliferation. METHODS: Rat BMSCs were divided into three groups: normal control group, 24-hour GW4869 treatment group and withdrawal of GW4869 for 24 hours group (24-hour GW4869 treatment followed by 24-hour successive culture with drug withdrawal). Cultured cells were collected to extract exosomes by ultracentrifugation. Western blot was used to detect exosome-associated proteins CD63 and tumor susceptibility gene 101 (TSG101). The concentration and size distribution of exosomes were measured using nanoparticle tracking analysis. BCA was used to test the level of total proteins in exosomes. Live cell imaging system was used to observe the influence of GW4869 on BMSCs proliferation. RESULTS AND CONCLUSION: (1) Western blot results showed that exosomes expressed marker proteins such as CD63, TSG101. (2) Findings from the nanoparticle tracking analysis confirmed that the size of released exosomes was about 114 nm. (3) Significantly reduced release of exosomes was found in the two treatment groups compared with the normal control group (P < 0.01), but there was no significant difference between 24-hour GW4869 treatment group and withdrawal of GW4869 for 24 hours group (P > 0.05). (4) No significant difference in the proliferation of BMSCs was found among the three groups (P > 0.05). To conclude, 24-hour W4869 can inhibit the release of exosomes by BMSCs and this inhibitory effect is still sustained within 24 hours after drug withdrawal. However, GW4869 has no influence on the proliferation of BMSCs.

BACKGROUND: Hyaluronic acid is an important component of extracellular matrix, has good biocompatibility, unique rheological properties and a variety of physiological functions. Therefore, it has wide application prospect in the tissue engineering. OBJECTIVE: To review the latest research progress in hyaluronic acid scaffold materials in different directions of tissue engineering. METHODS: Using the keywords of "hyaluronic acid, tissue engineering, regeneration, scaffold" in English and Chinese, we retrieved relevant articles published from January 2013 to September 2016 in the databases of PubMed, ScienceDirect and CNKI. RESULTS AND CONCLUSION: The application of hyaluronic acid tissue engineering scaffold materials mainly focuses on the regeneration of bone, cartilage, cardiovascular and nerve. The researchers optimize the composition, ratio of different materials, and modification or cross-linking methods to obtain the ideal scaffold materials to match the mechanical properties and physiological activity of the target tissue. However, there are not enough data on the influence of the molecular weight of hyaluronic acid and the original source of other raw materials on the scaffold properties. Further investigations are needed on the clinical transformation of hyaluronic acid tissue engineering products.

Objective: To investigate the current situation of drug supply and determinants of drug shortage in primary health institutions in Anhui province. Methods:Primary health institutions in Anhui province were selected as the main research subjects. One hundred and six (106) primary health institutions from three areas/districts in Anhui province namely northern Anhui,Central Anhui,and Southern Anhui were selected with stratified random sampling as the first sample,and 54 pharmaceutical producing enterprises and 62 pharmaceutical trading enterprises were selected with convenience sampling method as the second sample. The survey was conducted by issuing questionnaires to record views of the respondents to help understand the current situation of drug supply from the first sample and the main de-terminants and solutions of drug shortage from two samples. Results:13% of the primary health institutions still suffer from serious shortage of drug supply; the drug distribution rate varies greatly between units, and 19% of the primary health institutions have a drug distribution rate below 70%,and all primary health institution within the scope of inves-tigation experienced drug shortages. The frequency of choices of determinants of drug shortage were in sequence of or-der:drug demand instability (19.20%), drugs have a new and higher profit alternative (15.94%), etc.; The fre-quency of choices of solutions of drug shortage of primary health institution were in sequence of order:to improve the national list of essential medicines(12.78%),appropriate improvement in efficacy the low-priced varieties(with cura-tive effect) (12.03%),etc. Conclusions:Primary health institutions suffer from drug shortage issue widely,and the reasons for the shortage of drugs are more complicated;the government should continue to implement relevant policies, comprehensively improving the primary health institution drug supply mechanisms in all to prevent drug shortages.

Objective: To observe the effect of poloxamer 188 (P188) on megakaryocyte cultivation and induction from cord blood mononuclear cells in order to obtain more megakaryocyte progenitor cells (MPC). Methods: The cord blood mononuclear cells were isolated and inoculated in cell culture bag or cell culture flask respectively. The WIGGENS shaker and cell culture bags were used to mimick WAVE Bioreactor for three-dimensional (3D) cell culture, and the P188 was added to induction medium, The cells were detected for morphology, surface marker, viability, and number on day 14. Results: In the two-dimensional (2D) culture, CD41(+), CD41(+)/CD61(+), CD61(+) megakaryocytic numbers increased significantly after adding P188 (all P<0.01). And in the 3D culture of adding P188, the cell volume became larger and the nuclear shape was irregular, the cytoplasm appeared magenta granules, and the megakaryocyte cells became more mature. By 3D culture, the expression of CD41/CD61 was (36.30±1.27)% vs (23.95±1.34)%, hence the differentiation for MPC was significantly higher than that in the 2D group (P<0.01). Furthermore, adding P188 in 3D culture resulted in highest differentiation efficiency for MPC [(59.45±1.20)%]. There were no significantly differences in terms of cell viability and cell number among 3D culture containing P188, 2D and 3D culture groups (all P>0.05). Conclusion: 3D culture was beneficial for the differentiation of MPC, but the cell viability was lower than 2D group; However, the satisfied cell growth and better induction efficiency were obtained by adding of P188, which might provide a new method of megakaryocytes production for clinical application.

OBJECTIVETo investigate the changes of peripheral blood marrow-derived suppressor cell level after chemotherapy induction remission by regimen consisting of vincristine, daunorubicin, L-asparaginase and prednisone (VDLP) and to analyze their relationship with immume system in B-ALL children.

METHODSThirty B-ALL children after induction remission by VDLP regimen from August 2015 to August 2016 were selected as B-ALL group and 30 normal healthy children were selected as control group. The peripheral blood in 2 groups was collected and detected by flow cytometry, then the ratios of CD30cells and CD33HLA-DRmarrow-derived suppressor cells, CD14CD33HLA-DRmarrow-derived suppressor cells and CD15CD33HLA-DRmarrow-derived suppressor cells were calculated, and their changes after induction remission by VDLP regimen and the relationship with immune system were analyzed.

RESULTSAfter treatment the ratio of CD33cells in peripheral blood of B-ALL group and control group was not significantly different (P> 0.05), moreover, the ratio of CD33cells in B-ALL group was significantly higher than that before treatment (P<0.05), while the ratios of CD33HLA-DRmarrow-derived suppressor cells, CD14CD33HLA-DRmarrow-derived suppressor cells and CD15CD33HLA-DRmarrow-derived suppressor cells in B-ALL group were significantly lower than those in control group (all P<0.05), but the ratios of these cells in B-ALL group were higher than those before treatment, and yet there was no statistical significance (P>0.05).

CONCLUSIONThe ratios of marrow-derived suppressor cells in peripheral blood of B-ALL children in complete remission after treatment with VDLP regimen are higher than those before treatment, but are significantly lower than normal value, which may be related with non-complese recovery of immune system in B-ALL children after treatment.
