ABSTRACT
The interleukin family can directly or indirectly stimulates the proliferation, survival and diffusion of tumor cells, and further shapes the tumor microenvironment, thus affecting the tumor growth and transformation to a certain extent. Studies show that the new numbers of IL-12 family, IL-35, IL-39 and IL-27, play the relevant specific immune functions in a variety of tumors, which may be important target molecules for tumors research.
ABSTRACT
BACKGROUND:Structural and functional changes of endothelial cels are the common pathological basis of cardiovascular disease. Severe structural and functional damage of endothelial cels are found in patients with hypertension or coronary heart diseases. OBJECTIVE:To explore a new treatment method for hypertension from the perspective of vascular endothelial progenitor cels. METHODS: PubMed and Wanfang databases were retrieved using the keywords “hypertension, EPCs” and approximately relevant 200 English and 100 Chinese literatures were obtained. Forty-nine eligible literatures were screened finaly. RESULTS AND CONCLUSION:Endothelial progenitor cels have strong differentiation and proliferation capacities. This review may provide a new insight into potential sources of cels for diagnosis and treatment of hypertension.
ABSTRACT
Endotoxin,which is also called lipopolysaccharide (LPS),is a unique element of Gram-negative bacteria.Liver is the main site for removing bacteria and endotoxin.Meanwhile,it is also the most vulnerable organ.Liver injury initially occurs in the hepatic sinu-soids.This article mainly introduces the impact of LPS on Kupffer cells,hepatic sinusoidal endothelial cells,oxidant/antioxidant balance in the hepatic sinusoids,and liver blood flow.It is believed that the function of hepatic sinusoids in LPS-induced liver injury should not be ig-nored,and the hepatic sinusoids would play an important role in the prevention and treatment of LPS-induced liver injury.
ABSTRACT
<p><b>OBJECTIVE</b>To screen for CGG repeats in the FMR1 gene among patients with fragile X syndrome and carriers of pre-mutations.</p><p><b>METHODS</b>Potential full and pre-mutations of the FMR1 gene were detected with a Tri-primer-florescence PCR-Sanger sequencing method. The results were validated with positive and negative controls.</p><p><b>RESULTS</b>All positive and negative controls were confirmed. A male patient was found to have > 200 CGG repeats (full mutation). For a pregnant women who was heterozygous for 35/115 CGG repeats, > 200 CGG repeats were also found with amniotic fluid sample from her fetus who was a male. The result was confirmed by following selective abortion with informed consent.</p><p><b>CONCLUSION</b>Tri-primer-florescence PCR-Sanger sequencing is a simple, effective and reliable method for routine screening of patients/carriers with full/pre-mutations of the FMR1 gene in the population.</p>

Objective To select 15 short tandem repeat(STR) loci that are highly and steadily polymorphic,and study the genetic relationships between Luoba ethnic group,Tibetan living in Lassa and Changdu area,and other Asian populations by using 15 STR polymorphism.Methods The blood samples of unrelated individuals from Luoba ethnic group,Lassa Tibetan and Changdu Tibetan were collected.DNA templates were screened using AmpF/ STR Identifiler kit and ABI3100Avant DNA analyzer with Genescan and Genotype software.The STR data of Luoba,Lassa Tibetan,Changdu Tibetan,other 21 Chinese ethnic groups and six Asian populations were compared;phylogenesis tree was constructed;the genetic relationships among ethnic groups living in Tibet and other Asian populations were analysed.Results Eight Hans clustered,and five ethnic groups of Guangxi clustered firstly;then the two clustered with Luoba,and two groups of Tibetan secondly;and then clustered with other Chinese populations,and then the Chinese groups clustered with other six Asian populations and Chinese Uygur lastly.Conclusion The results of this study are basically consistent with geographic distribution,and histories of these ethnic groups.They can provide the genetic proofs for the origin,migration,formation and development of ethnic groups living in Tibet.
