Objective To explore and analyze the effects of different batches of fetal bovine serum(FBS) on the quality evaluation of human mesenchymal stem cells(hMSCs) products and provide reference for the development and quality control of hMSCs products.Methods Retrospective analysis was conducted on the immune-regulatory function data of standard cell line CCRC-hMSC-S1 cultured in medium supplemented with FBS from different batches, based on the quality review data of hMSCs products. The standard cell line CCRC-hMSC-S1 was co-cultured with allogeneic peripheral blood mononuclear cells(PBMCs) from 5-6 donors respectively, and five different batches of FBS(FBS-H, FBS-A, FBS-E1, FBS-E2 and FBS-E3)were added to the co-culture system to clarify the direct effects of different batches of FBS on the detection value of immuneregulatory function by CCRC-hMSC-S1. The hMSCs from eight different individuals were cultured respectively in five medium containing different batches of FBS for two weeks, and the immune-regulatory function and osteogenic differentiation capacity were evaluated to clarify the effects of long-term culture of different batches of FBS on the key quality attributes of hMSCs.Results In the co-culture system of hMSCs and PBMC, the detection value of regulatory T-cell(Treg) promotion rate in FBS-H culture system was significantly lower than that in FBS-A, FBS-E1, FBS-E2 and FBS-E3 culture systems(t = 3. 2,3. 0, 3. 2 and 2. 9, respectively, each P < 0. 05), and the detection value of T lymphocyte proliferation inhibition rate in FBSH culture system was significantly higher than that in FBS-A, FBS-E1, FBS-E2 and FBS-E3 culture systems(t = 3. 7, 3. 4,2. 8 and 3. 0, respectively, each P < 0. 05); the inhibitory ability of hMSCs long-term cultured in FBS-A on Th1 proliferation was significantly lower than that of hMSCs long-term cultured in FBS-H, FBS-E1, FBS-E2 and FBS-E3(t = 3. 0, 2. 4, 3. 7and 3. 3, respectively, each P < 0. 05); the suppressive effect of hMSCs long-term cultured in FBS-H on T lymphocyte proliferation was significantly higher than that of hMSCs long-term cultured in FBS-A, FBS-E1, FBS-E2 and FBS-E3(t = 4. 7,2. 6, 3. 4 and 3. 9, respectively, each P < 0. 05); the alizarin red S staining area of hMSCs long-term cultured in FBS-E3 after osteogenic differentiation was significantly lower than that of hMSCs long-term cultured in FBS-A, FBS-H and FBS-E1(t =4. 1, 5. 5 and 3. 9, respectively, each P < 0. 01).Conclusion In the research and development of hMSCs cell therapy products, it is necessary to pay close attention to the effects of FBS components on the quality evaluation of hMSCs, especially the immune-regulatory function and differentiation potential, and select suitable batches of FBS for the development and quality control of hMSCs products.

BACKGROUND:In recent years, research on tendinopathy is becoming a hot topic in the sports medicine and rehabilitation, and the extracelular matrix plays a considerable role in the occurrence, development and healing of tendinopathy.
OBJECTIVE: To explore the relationship between tendinopathy and the extracelular matrix.
METHODS: CNKI, VIP, CBM, Wanfang, PubMed and Embase were retrieved for articles related to colagen, protein, glycoprotein and matrix remodeling published since 2000.
RESULTS AND CONCLUSION:After tendinopathy, there are obvious changes in colagen, proteoglycans, glycoprotein and related enzymes; and these changes also affect the reconstruction and repair of tendinopathy. Currently, most of researches focus on the tendon rather than the bone-tendon junction. This means that there are no in-depth studies on the correlation between many important proteins and tendinopathy, and the effects of exercise intervention.

T was genotyped by polymerase chain reaction-restriction fragment length polymorphism(PCR-RFLP)in all the patients.Results The occurrence of CR in this population was 23.3%(70/300).There was CYP3A4 894C/T polymorphism in the study population.The frequencies of the three kinds of genotypes(CC,CT,TT)in CR group and non-CR(NCR)group were 45.7%,50.0%,4.3% and 63.5%,31.7%,4.8%,respectively.The frequency of TT genotype was significantly higher in NCR group than that in CR group(OR=2.06,95% CI:1.201-3.547,P=0.020).C allele carriers were more likely to develop clopidogrel resistance compared with that of T allele carriers(OR=1.59,95% CI:1.037-2.442,P=0.023).Conclusion CYP3A4 gene 894C/T polymorphism is associated with the risk of CR,and C allele carriers may be a possible genetic susceptibility factor for patients with CR.

Objective To investigate the clinical value of echocardiography combined with genetic testing in the fetal cardiac rhabdomyoma. Methods Thirty-three fetal cardiac rhabdomyoma cases diagnosed by fetal echocardiogram in Beijing Anzhen Hospital from Jan. 2011 to Oct. 2015 were enrolled in a retrospective analysis. The results of other examination and pregnancy outcomes of them were followed up, the genetic characteristics of cardiac rhabdomyoma were summarized on the basis of pathology and genetics examination results. Results The pregnancy outcomes:24 cases were terminated pregnancy, 4 cases were born and 5 cases were lost. The results of ultrasound, pathology and genetic examination were detailed in 8 cases. Pathological examination: the typical characteristics of cardiac rhabdomyoma were found in the 8 cases with cardiac rhabdomyoma. The tumor tissue was composed of irregular and swelling shape of cardiomyocytes, and the cytoplasm was vacuole like, which was characteristic of“spider like cells”through microscopic observation. The geneticdetection results: 7 cases had tuberous sclerosis complex (TSC) gene mutation, TSC gene abnormalities were not detected in 1 case. Among the 7 cases with TSC gene mutations, 6 cases were with TSC2 gene mutation and the other 1 case was with TSC1 gene mutation. The family gene was investigated in the 5 cases, which including 3 cases of TSC gene mutation in mother passed on to the fetus (1 case with family of three generations of genetic) and 2 cases of spontaneous TSC gene mutation in the fetus. Conclusions Prenatal echocardiography combined with genetic detection have important clinical significance, which not only can clear if cardiac rhabdomyomas were associated with TSC, but also can clear the TSC gene mutation source. So as to further guide the perinatal management.

It is reported by current investigations,that BNP can suppress heart hypertrophy but it can also depress compensatory hypertrophic response.BNP is an useful marker in the early diagnosis,prognosis,therapy guiding of heart failure and coronary heart disease,but comorbid conditions should be considered in the diagnosis of heart failure.The polymorphism in the 5'-flanking region of the NPPB gene is found to be related with essential hypertension.On the basis of some investigation,it is supposed that the instillation of BNP at the early stage of hypertension will contribute to therapy of hypertension.

OBJECTIVE:To explore the role of clinical pharmacists in tumor pain management for patients receiving tumor pain palliative radiotherapy. METHODS:In prospective randomized controlled study, 60 patients with tumor pain who received palliative radiotherapy in radiotherapy department of our hospital from June 1,2013 to May 31,2014,according with the selection criteria,were randomized into observation group(30 cases)and control group(30 cases). Clinical pharmacists participated in the treatment of observation group;provided pharmaceutical care for doctors;and recorded drug treatment,pain evaluation,medica-tion compliance,Karnofsky Performance Status(KPS)and quality of life(QOL)of 2 groups. RESULTS:On the 5th day,the pain remission rate of observation group reached 63.3%,and was significantly higher than that(36.7%)of control group(P<0.05). 1 month treatment later,pain remission rate of 2 groups reached 70% and 80%,respectively (P>0.05). At the same time,KPS, QOL and medication adherence were all improved significantly,compared with before treatment(P<0.01 or P<0.05),and medi-cation adherence of observation group was obviously better than that of control group(P<0.01). CONCLUSIONS:The participa-tion of clinical pharmacists in the pain management can obviously improve medication compliance,relieve pain more effectively, and promote rational drug use.
