1.Mesenchymal stem cells and tumor biological treatment
Journal of International Oncology 2011;38(4):254-257
Mesenchymal stem cells (MSCs) are oonsidered as the ideal engineering cells because of their accesibility, their in vitro amplification capacity, low immunogenicity and their tendency toward the tissues. Modification of these cells to express specific anti-cancer molecules or to be a vector for targeted anticancer therapy become a hotspot of biological therapy in recent years. The continual development of MSC study shows great advantage as biological treatment on tumor.

AIM:To investigate the effect of fluvastatin on the expression of serum and glucocorticoid inducible kinase 1 ( SGK1) and connective tissue growth factor ( CTGF) induced by aldosterone ( Ald) in rat mesangial cells (GMCs). METHODS:GMCs were divided into (1) control group; (2) aldosterone group with different concentrations and times; (3) Ald (10 -7 mol/L) + spironolactone (10 -9 mol/L) group; (4) Ald (10 -7 mol/L) + LY294002 (20 ?mol/L) group; (5) Ald (10-7mol/L) +SB203580 (20 mmol/L) group; (6) the group of Ald (10-7mol/L) + fluvas-tatin at different concentrations (10-7,10-6,10-5 mol/L); (7) Ald (10 -7mol/L) + fluvastatin (10 -5mol/L) + mevalonate (10 -4 mol/L) group; (8) Ald (10 -7 mol/L) + fluvastatin (10 -5 mol/L) + FPP (farnesyl pyrophosphate,10-4 mol/L) group; (9) Ald (10 -7mol/L) + fluvastatin (10 -5 mol/L) + GGPP (geranylgerany pyrophosphate,10 -4 mol/L) group. The protein levels of SGK1 and CTGF were determined by Western blotting. The levels of fibronection (FN),monocyte chemoattractant protein-1 (MCP-1) and intercellular adhesion molecule-1 (ICAM-1) in the supernatants were determined by enzymelinked immunosorbant assay (ELISA). RESULTS:Aldosterone stimulated the protein expression of SGK1 and CTGF in cultured mesangial cells in a dose-dependent manner (P

Objective To investigate the expression and significance of IL-6 and IL-6 receptor (IL-6R)in hysteromyoma.Methods The expression of IL-6 in hysteromyoma and homologous normal myometrium of 20 cases undergoing total hysterectomy were detected by fluorescent quantitative PCR and western-blot,respectively while IL6R was examined by western-blot and RT-PCR.Results The expression of IL-6 protein and mRNA in homologous normal myometrium were obviously higher than that in hysteromyoma[(0.7996 ±0.0359)vs (0.6904 ±0.0414)and (0.0470±0.0071)vs(0.0283±0.0045 ),P<0.05] ;No difference was observed in IL-6R protein and mRNA expression between leiomyomas and myometrium[(0.7105 ±0.0520)vs (0.6904 ±0.0532)and (0.6644 ±0.0537 )vs (0.6465±0.0501),P>0.05 ].Conclusion The lower expression of IL-6 in leiomyomas may contribute to the pathogenesis of hysteromyoma to some extent,and there is no relationship between IL-6R and hysteromyoma.

Objective To estimate the clinical value of 4 methods of endometrium preparation for frozen‐thawed embryo transfer(FET ) cycle .Methods Total 320 FET cycles completed in center of reproductive medicine of Qingyuan people′s hospital from March 2013 to March 2015 were retrospectively analyzed ,and divided into 4 groups :natural cycle group(group A ,n=70) ,o‐vulation‐inducing cycle group(group B ,n=152) ,hormone replacement treatment(HRT) cycle group (group C ,n=74) ,down‐regu‐lated HRT cycle (group D ,n=24) .The pregnancy outcomes were followed and compared among these different 4 groups .Results In FET cycles ,the clinical pregnancy rates and implantation rates of group B ,group C and group D were significantly higher than that of group A (P<0 .05) ,there were no significant differences in the rates of multiple pregnancy ,biochemical pregnancy ,early a‐bortion and ectopic pregnancy among 4 groups(P>0 .05) .However ,the rank of the FET cycle of group D was significantly higher than those of the other three groups(P<0 .05) .Conclusion In FET cycles ,the methods of ovulation‐inducing ,HRT and down‐reg‐ulated HRT all have favorable clinical outcomes ,and the method of down‐regulated HRT is more suitable for patients with previous implantation failure .

Objective To analyze the characteristics in the incarcerated inm ate’s death, investigate the m ain cause of death of the incarcerated inm ate and provide som e inform ation for forensic investigation. Methods The cases from the forensic m edical center of Shanxi Medical U niversity from 2005 to 2013 were selected. The statistical analysis w as perform ed by using the incarcerated inm ate’s gender, age, cause of death, m anner of death, and disease as the m arkers. Results There were 100 men, 5 w omen in the 105 incarcerated inm ates;the age range w as from 16 to 65 years;Inm ates were mostly died of nat-ural diseases, m ainly in the respiratory and cardiovascular diseases;the m ain unnatural death w as suicide w ith a rate of 54.5%. Conclusion Atpresent, most incarcerated inm ate’s death are due to natural dis-eases. The prison should im prove incarcerated inm ate’s lives, w ork and health care conditions, and strengthen supervision of law enforcement.

Aim To study the protective effect of tetra-hydroxystilbeneglucoside ( TSG ) on cardiac injury and the mechanism involved in silent mating type informa-tion regulation 2 homolog 1 ( SIRT1 ) and adenosine monophosphate-activated protein kinase( AMPK) in the diabetic rats. Methods Type 2 diabetic rats were sac-rificed after administration with TSG for 8 weeks. Blood glucose, blood lipids, liverfunction,creatine ki-nase ( CK ) , lactate dehydrogenase ( LDH ) as well as myocardial nonesterified fatty acids( NEFA) were deter-mined by using biochemical test. The concentration of myocardial fatty acid transport proteins ( FATPs ) and-fatty acid β-oxidase ( FA-β-oxidase ) , and the levels of tumor necrosis factor alpha ( TNF-α) , interleukin -6 ( IL-6 ) , interleukin-1β( IL-1β) in serum were also measured by ELISA method and radio immunoassay re-spectively. The protein expressions of TNF-α, IL-6, IL-1β, SIRT1 and AMPK were detected by Western blot. Results Treatment of TSG reduced the contentof blood lipids, NEFA and collagen without affecting the content of blood glucose and insulin. The levels of TNF-α, IL-6 and IL-1βin serum as well as the protein expressions of TNF-α, IL-6 and IL-1β of cardia were also inhibited by administration with TSG. Treatment of TSG caused a significantly increased concentration of myocaidial FATPs and FA-β-oxidase, and dramatically restored the decreased protein expressions of SIRT1 and pAMPK in diabetic rats. Conclusion The protec-tive mechanisms of TSG against diabetic rats are in-volved in the alleviation of inflammatory mediator injury and improving energy metabolism.

AIM: To study the effect of ligustrazine on the cardiacmyocyte lesion in rats with type 2 diabetes mellitus.METHODS: Male Wistar rats were injected with STZ via tail vein under high-glucose and high-fat feeding for 4 weeks to establish the animal model of type 2 diabetes mellitus.Ligustrazine at different doses was used to treat the diabetic rats.The body weight, blood glucose and the morphology of heart tissues were observed.The myocardial levels of IL-1β, IL-6 and TNF-α were detected by ELISA, and the protein expression of IKKβ and NF-κB in the myocardium was determined by Westeren blotting.RESULTS: Ligustrazine at high dose alleviated the body weight reduction and blood glucose elevation cause by diabetes, and reduced pro-inflammatory factors IL-1β, TNF-α and IL-6.Moreover, the protein expression of IKKβ and NF-κB was significant decreased by ligustrazine.CONCLUSION: Ligustrazine inhibits the myocardial inflammation caused by diabetes through anti-inflammatory pathway.

OBJECTIVE To discuss the risk of tuberculosis infection in a general hospital workers.METHODS In a cross-sectional survey,we studied purified protein derivative(PPD) test in exposure group and control group.(RESULTS) The positive rate of PPD test in the hospital workers was 84.1%,significantly higher than that in(controls)(52.1%,P0.05).The positive PPD in workers of respiratory(department) was 2.95 times higher than in those of other departments.CONCLUSIONS The(environment) of(hospital) is special.Tuberculosis infection threatens the health of hospital workers.So we suggest that hospital workers(improve) self-protective consciousness and actively prevent tuberculosis infection,especially for(internes) and(physicians) with negative PPD.
