Objective Preterm birth is a live birth delivered before 37 weeks of gestation.Preterm birth rates have risen in recent years,and preterm birth is the leading cause of perinatal morbidity and mortali-ty worldwide.Both environmental and genetic factors likely play important roles in the development of pre-term birth.MicroRNAs(miRNAs)are 18 to 25 nucleotides,single stranded non-coding RNAs that regulate a wide range of biological processes in development and human disease.In this study,we have investigated the differential expression of hsa-miR-28-3p and ADAM12 in cord blood mononuclear cells of preterm birth and term birth.Methods The cord bloods were collected from the patients of Putuo District Institute of Materni-ty and Child Health.The preterm group(30 patients)was the patients with spontaneous preterm delivery,and the control group(30 patients)was the patients delivered normal infants at term.The expression levels of hsa-miR-28-3p and ADAM12 mRNA were directly generated by real-time PCR.Results The gestational age and birth weight of preterm group was(30.92 ±1.73)weeks and(1 646 ±357)g,and the control group was (39.73 ±0.58)weeks and(3 301 ±394)g.The hsa-miR-28-3p expression of preterm group(1.03 ±0.23) was significantly lower than that of control group(2.32 ±0.52)in the peripheral blood mononuclear cells (P <0.01 );the ADAM12 mRNA expression of preterm group(0.037 8 ±0.005 6)was significantly higher than that of control group(0.027 6 ±0.003 9)(P <0.05);the hsa-miR-28-3p expression was significantly correlated with the ADAM12 mRNA expression(r =-0.634 1 ,P <0.01 ).Conclusion The lower hsa-miR-28-3p expression of cord blood mononuclear cells may up-regulate ADAM12 mRNA expression,and promotes the occurrence of spontaneous preterm birth.

Objective To evaluate the effect of hypothermia on the expression of dynamin?related protein 1 ( Drp1) in brain tissues during global cerebral ischemia?reperfusion ( I∕R) in rats. Methods Thirty?six healthy male Sprague?Dawley rats, weighing 280-320 g, were divided into 3 groups ( n=12 each) using a random number table: sham operation group ( group Sham ) , global cerebral I∕R group ( group I∕R) and hypothermia group ( group H) . Cardiac arrest was induced by transoesophageal cardiac pacing followed by cardiopulmonary resuscitation to establish the global cerebral I∕R model in anesthetized rats in I∕R and H groups. In group H, the body temperature ( rectal temperature) was cooled down to 32-34 ℃ within 15 min starting from the beginning of reperfusion, and maintained at this level for 6 h. At 72 h of reperfusion, neurological deficit was scored, and the rats were sacrificed, and the whole brain was removed for examination of the pathological changes in hippocampal CA1 region and for determination of nor?mal pyramidal cell count and neuronal apoptosis in hippocampal CA1 region and expression of Drp1 and cy?tochrome c (Cyt c) in hippocampal tissues (by Western blot). The apoptosis rate was calculated. Re?sults Compared with group S, the neurological deficit score and apoptosis rate were significantly in?creased, and the number of normal pyramidal cells was decreased in I∕R and H groups, the expression of Drp1 and Cyt c in hippocampal tissues was significantly up?regulated in group I∕R ( P<0.05) , and no sig?nificant change was found in the expression of Drp1 and Cyt c in hippocampal tissues in group H ( P>0.05) . Compared with group I∕R, the neurological deficit score and apoptosis rate were significantly de?creased, the number of normal pyramidal cells was increased, and the expression of Drp1 and Cyt c in hip?pocampal tissues was down?regulated in group H ( P<0.05) . Conclusion The mechanism by which hypo?thermia inhibits cell apoptosis during global cerebral I∕R may be related to down?regulation of Drp1 expres?sion in rats.

Objective To explore the CT and MRI manifestations and clinical features of juxtaglomerular cell tumor (JGCT). Methods A retrospective analysis the data of eight JGCT patients who resected by surgery and comfirmed by histopathology. Seven cases were examined by CT before operation, five of whom underwent CT scan and dynamic enhanced scan, two of whom underwent CT scan, and all of the eight underwent MRI scan and dynamic enhanced scan. The clinical manifestations of patients were also observed, whether they have hypertension and reduced blood potassium, recorded the results of lying and standing test, and collected the segmental renal vein blood to detect the renin levels. Meanwhile, the CT and MRI manifestations were also recorded. Results (1) We found that all of the eight patients appeared hypertension, and hypokalemia were found among five cases. Seven patients proceeded the lying and standing test, six of whom the plasma renin activity (PRA) were elevate in erect position, and the levels of angiotensin Ⅱand aldosterone (ALD) were rised among all of the seven cases in erect position. Four patients were collected the segmental renal vein blood, and one of whom has positive result of the renin activity. (2) The tumors of all the eight cases were single, the border was clear, and the average size was 2.7 cm (range 1.9 to 3.8 cm). The CT scan results showed there's no calcification or pseudocapsule were detected, four cases showed homogeneous iso-density, one case with slightly high density, another one showed low density with dotty high density and one case with low density. The dynamic enhanced CT scan showed that four cases performed continuous enhancement from cortical to medullary phase, and no obvious enhancement was found in one case. The T2WI results of MRI scan showed six cases had pseudocapsule, 6 cases had heterogeneous signal (4 cases with patchy low signal and 2 cases with patchy high signal), and 2 cases had homogeneous signal (one case with iso-high signal and another with high signal). The T1WI results showed two cases performed low signal, anther two cases showed iso-signal, and four cases with heterogeneous signal. The DWI results showed all of the 8 lesions with homo-or peripheral high signal. The dynamic enhanced MRI scan results showed seven cases performed gradual enhancement, and the border of another case became clear on delay phase. Conclusions JGCT has specific clinical and imaging features, and the combination will help make a correct diagnosis.
