BACKGROUND:Studies have shown that microRNAs (miRNAs) have moderating effect on the renewal and differentiation of cancer stem cels. However, there is no complete understanding on the effect of microRNA-17-92 gene on gastric cancer stem cel renewal and proliferation.
OBJECTIVE:To explore the effect of miRNA-17-92 in promoting self-renewal and proliferation of gastric cancer stem cels.
METHODS:(1) The gradualy reduced miRNAs during gastric cancer stem cel self-renewal were investigated using miRNA array based on RNAs from differentiated and adherent cels. (2) The miRNA-17-92 was constructed and transfected to gastric cancer stem cels. (3) The effects of miRNA-17-92 on the self-renewal of gastric cancer stem cels were studied by tumor sphere assayin vitro. (4) The effects of miRNA-17-92 on the proliferation of gastric cancer stem cels were investigated by MTT assay and colony formation assay.
RESULTS AND CONCLUSION:(1) miR-19b/20a/92a expression gradualy reduced in the adhesion and differentiation of gastric cancer stem cels. (2) The expression of lentivirus carrying miRNA-17-19 gene in MKN28 cels and CD44-/EpCAM- cels were significantly increased; transient transfection of pre-miR-19b/20a/92a increased the expression of CD44-/EpCAM- and MKN28 miRNA, transient transfection of pre-miR-19b/20a/92a antagonists reduced the expression of SGC7901 and CD44+/EpCAM+ miRNA; overexpression of lenti-miR-19b/20a/92a significantly increased the ability of gastric cels to form tumor spheres; chemotherapy drugs prolonged the survival time of lenti-miR-19b/20a/92a-infected cels; transient transfection of pre-miR-19b/20a/92a significantly increased the number of CD44+/EpCAM+ cels, but transfection of pre-miR-19b/20a/92a antagonist reduced the number of CD44+/EpCAM+ cels. (3) MTT proliferation assay showed that gastric cancer cel proliferation rate in miR-19b/20a/92a stably expressing group was faster than that in the control group. Transient transfection of miR-19b/20a/92a precursor accelerated the growth rate of gastric cancer cels, and transient transfection of its antagonist slowed down the growth rate of gastric cancer cels. Colony formation assay showed that transient transfection of miR-19b/20a/92a precursor significantly increased the colony formation number as compared with the control group; transient transfection of miR-19b/20a/92a antagonist reduced the colony formation as compared with the control group. These findings indicate that miR-19b/20a/92a gene presents with continuous deletion in gastric cancer stem cel differentiation process, and miRNA-17-92 gene can promote the renewal and proliferation of gastric cancer stem cels.

Objective To explore the influence of abnormal donor hepatic artery on hepatic artery and biliary complications after liver transplanta?tion,and summarize the hepatic artery reconstruction procedures during transplantation. Methods The clinical data of 210 cases of liver transplan?tation conducted in our hospital from May 2005 to April 2015 were retrospectively searched for the study,including 42 with abnormal donor hepatic artery. Results Among the 210 liver transplantation,42 cases exhibited abnormal donor hepatic artery,and the aberration rate was 20.0%. Mean volume of blood flow of abnormal group and normal group was 4.7±95.1 mL/min and 190.9±101.6 mL/min,respectively. There was no statistic differ?ence(P=0.519). Twelve cases had arterial complications,the incidence rate was 5.71%,and there was no statistic difference between each group (χ2=0.72,P>0.05). Twenty five cases got biliary complications,the incidence rate was 11.9%,and there was no statistic differences between each group(χ2=0.05,P>0.05). Conclusion There was no statistic difference of mean volume of blood flow after arterial reconstruction between two groups. Liver transplantation with abnormal arterial reconstruction will not increase the incidence rate of arterial and biliary complications.

Objective To investigate the risk factors, diagnostic evaluation, etiology, and treatment in young patients with ischemic stroke. Methods The clinical data of young patients (age range 18 - 45 years) with ischemic stroke (within 2 weeks of stroke onset) admitted to the Stroke Center, the First Affiliated Hospital of Sun Yat-sen University from August 2008 to July 2013 were registered prospectively. Results A total of 300 patients were enroled, their age was 37. 8 ± 6. 8 years. There were 227 males (75. 7% ). The age of 84 patients (28. 0% ) was ≤35 years. The most common risk factors were smoking (43. 3% ), hypertension (38. 7% ), and hypercholesterolemia (38. 0% ). The positive result detection rates were lower in the antinuclear antibody (8/278), anticardiolipin antibody (34/250), 24-h Holter monitoring (2/60 ), and transthoracic echocardiography (38/232). According to the MRI findings, the detection rate of the white matter changes, old infarcts, single acute infarcts, and multiple acute cerebral infarcts were 40/282, 77/282, 145/282, and 137/282, respectively. The stroke subtypes of TOAST: large artery atherosclerosis (26. 7% ), smal artery occlusion (18. 0% ), cardioembolism (10. 0% ), other determined etiology (23. 0% ), and undetermined etiology (22. 3% ). Large artery atherosclerosis was mainly involved in anterior circulation (69/80) and intracranial arteries (75/80). In other definite causes, cerebral artery dissection was most common (36/69), and other causes included moyamoya disease (7/69) and infectious vasculitis (7/69), etc. The average length of hospital stay was 15. 4 d. The mean National Institutes of Health Stroke Scale score on admission was 7. 0, and the mean modified Rankin scale score at discharge was 2. 5. The complication rate during hospitalization was 9. 7% . 80. 3% and 48. 3% of patients received anti-platelet drugs and statins therapy during hospitalization.Conclusions This study used a prospective single-center method. It conducted a comprehensive analysis of risk factors, diagnostic evaluation, treatment, and etiology in current Chinese young patients with ischemic stroke. Its research data wil provide useful information for establishing a diagnostic strategy of high performance cost ratio, in-depth understanding of its pathophysiological mechanisms, and improving treatment strategies in Chinese young patients with ischemic stroke.

Objective To investigate the values of conventional magnetic resonance imaging (MRI),magnetic resonance angiography (MRA),and high-resolution MRI for diagnosing intracranial arterial dissection (IAD)caused ischemic stroke. Methods From August 2008 to April 2015,59 consecu-tive patients (age 45 ±15years,41males)with IAD caused ischemic stroke admitted to the First Affiliated Hos-pital of Sun Yat-Sen University were enrolled prospectively. All patients underwent conventional cranial MRI/MRA examination,25 of them underwent whole brain DSA examination,and 10 underwent high-resolution MRI. The findings of conventional MRI/ MRA and high-resolution MRI of IAD were analyzed. For patients undergoing DSA,the proportions of detection and compliance of IAD were compared between DSA and conventional MRI / MRA. Results (1)Conventional MRI / MRA revealed typical sign of artery dissection in 42 patients (71. 2%),among them,the intramural hematoma (n = 22,52. 4%)was most common. Other common signs included intimal flap/ double lumen sign (n = 13,31. 0%)and long irregular or thread-like stenosis (n = 9,21. 4%);while dissecting aneurysm (n = 7,16. 7%)and rat tail-shaped occlusion (n = 3, 7. 1%)were relatively rare. In 17 patients (28. 8%)with IAD that conventional MRI/ MRA did not detect the typical dissection sign,the dissections were involved in the middle cerebral artery (11 / 17,64. 7%), they were more common than the 42 patients with IAD (10 / 42,23. 8%)detected the typical dissection sign by conventional MRI/ MRA. There was significant difference (P = 0. 006). (2)Among the 25 patients undergoing DSA,DSA revealed that 15 patients (60%)had the typical dissection sign,and conventional MRI/ MRA only revealed 8 of them (32%)with the typical dissection sign,but there was no significant difference (P = 0. 088). In 15 patients with IAD that DSA detected the typical dissection sign;conventional MRI / MRA detected the typical dissection sign in 8 of them. The diagnostic coincidence rate was 8 / 15. (3)Both conventional MRI/ MRA and DSA revealed non-specific limitation stenosis or cut-off occlusion in 10 patients (16. 9%)with IAD,while the high-resolution MRI revealed intimal flap in 5 of them,intramural hematoma in 4,and intimal flap and intramural hematoma in 1. Conclusion Conventional cranial MRI/MRA is an effective technique for revealing IAD,whereas high-resolution MRI has the unique advantages for diagnosing IAD without typical dissection in other vascular imaging.
