Objective To investigate the charateristic CT features of pediatircs reproductive system of endodermal sinus tumor. Methods Thirteen cases with pediatircs reproductive system of endodermal sinus tumor confirmed by surgery and biopsy pathology all underwent CT and contrast-enhanced CT scans,and theire imaging features were then ananlyzed.Results On CT scan,7 cases of testicular or vagina endodermal sinus tumor of children appeared soft tissues mass with uneven density,small patchy hypodense shadows,and ill-defined boundaries.Contrast-enhanced CT scans reveal the solid masses were obvious uneven continuous enhance-ment,but small patchy hypodense shadows were not enhanced,local envelope were enhanced.CT scans reveal that 6 cases of ovaries endodermal sinus tumor showed the large cystic solid mass,predominantly cystic mass,including 2 cases of punctate and patchy cal-cification,and contrast-enhanced CT scans showed that solid part were enhanced obviously and with obvious strengthening vessels shadows.1 case of right ovaries endodermal sinus tumor with fat density shadow and small patchy calcification.Its pathological di-agnosis was the endodermal sinus tumors with mature cystic treatomas.Conclusion CT image has an advantage in the diagnosis of endodermal sinus tumor of the children's reproductive system,especially combined with serum AFP determination.

Brain natriuretic peptide consists of 26 amino acids and has diuretic, natriuretic and hypotensive activities. We have synthesized BNP and its analog (BNP-A) (Mpr4, D-Ala613)-BNP(4-26)-NH2 using solid phase method and examined their biological activities. Our results showed that 1) BNP (10-7mol/L) dilated human basal cerebral artery which was pre-constricted with endothelin, 5-HT and noradrenaline in vitro; 2) both BNP (5 ?g/ rat) and BNP-A (5 ?g/ rat) increased regional cerebral blood flow following i.v. injection in rats; 3) intracerebroventricular injection of BNP (3 ?g/ rat) induced an obvious natriuretic effect when blood volume was extremely expanded with hypoosmotic glucose solution in rats; 4) BNP (5 ?g/ rat) infusion for 60 minutes caused a decline of plasma concentration of angiotensin II and aldosterone at the end of infusion in spontaneous hypertensive rats (SHR), and the bolus injection of BNP (10 ?g/ rat) led to a fall in blood pressure about 1.33kPa. We conclude that BNP is an important peptide in regulating water and sodium metabolism and plays an important role in regulating blood flow to various organs.

The incidence rate of epithelia ovarian cancer is high. The recurrence rate is also high. To improve the survival quality of patients and extend their life time as far as possible, and according to the recurrence epithelia ovarian carcinoma's different situation, we can selectively perform surgery, and combined it with appropriate chemotherapy and biological treatment. This article summarized its treatment from surgery, chemotherapy and biological therapy, these three aspects.

Objective To analyze the expression of BDNF, NGF,GFAP in Wistar rat pretectel area and determine the relation between neuron damage and neurotrophin change of pretectal area and retinal neurodegeneration in the early stage of diabetes. Methods Male Wistar rats weighing about 200 g were used to create diabetic animal model by injecting STZ. Wistar rats were killed by heart perfusion with 4% FDP at 1-week, 2-week and 1-month after diabetes. The dissected pretectal area was used to determine the expression of BDNF, NGF and GFAP with immunohistochemistry. Results In pretectal area of diabetic rat, the expression of BDNF and NGF began to decrease from 1-week DM, the expression of GFAP began to increase from 2-week DM. Conclusions There are neuron damage and neurotrophin decrease in the pretectal area in the early stage of diabetes. Neurodegeneration and neurotrophin decrease in pretectal area, which is the target tissue of retina, might be one of the reasons resulting in retinal neurodegeneration at the early stage of diabetes.

The symptoms score was used to evaluate the clinical efficacy.ResultsThe scores of appetite loss (0.65 ± 1.00vs. 2.32 ± 1.28,t=5.631), abdominal distention (0.73 ± 0.23vs.1.33 ± 0.97,t=3.297) and fatigue (0.72 ± 0.32vs. 1.42 ± 1.18,t=3.136) in the treatment group were significantly lower than those in the control group (all P<0.05). The total effective rate for syndrome of spleen deficiency in the treatment group was significantly higher than thatin the control group(90.0%vs.66.7%;χ2=4.812,P<0.05).ConclusionYigongpowder withYupingfeng powder can significantly improve the symptoms of syndrome of spleen deficiency in children with mycoplasma pneumoniae pneumonia.

This paper briefly describes the mechanism of neurochemical changes in AD,the roles of the epigenetics,the regulation of gene expression and the mechanism of epigenetics in SAD.On the basis of the basic study on the AD during the decades,researchers initially revealed the mystery of the unfathomable neurochemical changes attack on AD.Especially in recentyears,researchers summarized the abnormal protein expression on SAD into epigenetics disease.This achievement helps researchers point out the new and strategic direction on AD pathogenesis,prevention and control mechanism.With the understanding of biological characteristics of epigenetics,AD needs to be studied in depth.

The hypothesis of tumor stem cells believes that a small proportion of cells which have the stemness property reside in tumor. This population is the cause of tumor formation, growth, metastasis and relapse. Only the therapy targeting this population could make tumors curable. At present, most anti-cancer protocols only kill the majority of differentiated tumor cells and hardly affect the tumor stem cells. That is why most of the therapies do not achieve good results. Disrupting the pathways and niche which regulate the tumor stem cells’ self-renewal, or inducing the tumor stem cells’ differentiation, or targeting the surface markers which distinguish the tumor stem cells from normal stem cells are all probable strategies.
