International Journal of Pediatrics 2012;39(3):220-223
Patent ductus arteriosus is a common congenital heart disease in children.Effective and promptly treatment can prevent complications,such as pneumonia,congestive heart failure,infective endocarditic and pulmonary artery hypertension.The treatments include medication,transcatheter intervention and surgery.The vast majority of the patent ductus arteriosus can be cured by transcatheter interventional therapy now.
2.Impact of uterine artery embolization for fibroids on ovarian function in young woman
Chinese Journal of Postgraduates of Medicine 2009;32(9):7-10
Objective To evaluate the impact of uterine artery embolization (UAE) tor uterine fibroids on ovarian function in young woman. Methods From 50 young patients with symptomatic leiomyomas managed with UAE, completed follow-up 24-36 months of clinical symptomatic, ovarian function continue and pregnancy outcome. All patients participants ranged in age from 24 to 40 years, divided into lower 35 years group (30 cases)and over 35 years group (20 cases). Results There was no significant difference in serum FSH, LH and E2 levels between two groups before UAE and 3-6, 12, 24-36 months after UAE(P > 0.05).The comparison of serum FSH, LH and E2 levels between two groups at the same time points before and after UAE were no significant difference (P> 0.05). Menstrual blood loss reduced and duration of flow shorted after UAE in two groups, the differences were significant (P < 0.05). Cycle interval in over 35 years group was longer in 3-6 months after UAE than that before UAE, the difference was significant (P <0.05). There were 2 patients occurred transient secondary amenorrhea after UAE in lower 35 years group, 3 patients occurred in over 35 years group. One patient had menopausal syndrome in 37 months after UAE, and serum FSH and LH levels were found to heighten obviously, 47% pregnancies and 30% deliveries in lower 35 years group, 45% pregnancies and 20% deliveries in over 35 years group. Conclusion Transient secondary amenorrhea would have been occurred in young patients with uterine fibroid performed UAE, no prematureo varian failure and premature menopause.

The microRNA (miRNA) is a novel class of small noncoding RNA that regulate gene expression by targeting mRNA.It has been shown to play important roles in a broad range of biological processes,especially in the occurrence,development,invasion and metastasis of malignant tumors.Conventional detection methods,such as Northern blot and realtime PCR have been used to assess endogenous miRNA expression.However,these techniques are invasive and cannot be used repetitively in living animals.Recent remarkable advances of in vivo imaging techniques have provided the capability of noninvasive imaging of miRNA in vivo.The recent progress about the reporter gene,antisense luminescence,nanoparticle and multimodal imaging for visualizing miRNA expression in vivo was reviewed.

Objective To investigate the efficacy of MSCs infused intravenously on the regeneration of injured spinal cord and rehabilitation of its neurological function. Methods 32 SD rats, male or female, weight about 300 g for each one. MSCs were separated, cultured and purified in vitro. Surface marker of MSCs, such as CD34, CD45, CD29 and CD90 were detected by flow cytometry. The rat spinal cord injury model was prepared according to the modified Allen method. After exposure of T10 spinal cord, the T10 segment of spinal cord was injuried by a 10 g weight falling down from 5 cm high place upon a round thin copper pad which was placed on the surface of T10 segment of spinal cord. The diameter of the copper pad is 3 mm. There are 24 rats in the injuried group and 8 in the non-injuried group. The injuried group was then divided into experiment group with 14 rats and control group with 10 rats at 24 hours after preparation of models. The rats in the injuried group and non-injuried group were infused with MSCs marked by Brdu through tail vein, and the rats in control group were infused with PBS. The neurological functions of rats were evaluated at 24 hours after injury and 1, 3, 5 weeks post-infusion respectively. At the same time, the immigration, survival and differentiation of MSCs were observed. Results The MSCs were uniformly CD29, CD90 positive and CD34, CD45 negative. In vivo experiment, transplanted MSCs survived and were localized to the injured spinal cord, and a few cells expressed NSE, MAP2 post transplantation 3 to 5 weeks. Significant improvement in functional outcome in rats treated with MSCs transplantation compared to control rats. The score of BBB in the treated group was higher than that in the control group (P

As an important resource for a country to participate in international high-tech competition in the bio-pharma-ceutical field, clinical research resources play a key role in the multi-center clinical research and the translation from basic research to clinical practice.China has a large population and diverse diseases, but chinical disease research relevant policies and regulations are imperfect.In contrast, the United States has perfect laws and regulations related to clinical research.By comparatively analyzing the disease resource, platform support and regulatory environment between China and the U.S., this article offers suggestions on the development of clinical research resources so as to facilitate the clinical research in China.

Objective To compare the effect of crystalloid and crystalloid plus albumin in the treatment of pediatric septic shock.Methods Data of 63 pediatric patients with septic shock admitted to Department of Critical Care Medicine of Hebei Provincial Children's Hospital were collected and retrospectively analyzed.The patients were divided into two groups according to whether they received albumin for volume resuscitation within 1 day after admission or not.The patients in observation group (crystalloid + albumin group,n =33) received normal saline (20 mL/kg) followed by 1 g/kg albumin 30 minutes after admission,and those in control group (crystalloid group,n =30) received only normal saline (20 mL/kg) 30 minutes after admission,and normal saline resuscitation was continued according to the effect of fluid therapy.Anti-infection and vasoactive drugs strategies were the same in both groups.The first-hour infusion volume,time showing stable hemodynamics,the incidence of pulmonary edema,and blood lactate levels at 0,6,12 hours after achieving the goals were compared,and blood lactate clearance rates were calculated.Results The first-hour infusion volume time in the observation group was lower than that in control group (mL:41.56 ± 10.50 vs.57.24 ± 7.54,t=4.596,P=0.000),and time showing stable hemodynamics was shorter than that in control group but without statistically significant difference (minutes:219.87 ±70.23 vs.287.10 ± 67.00,t=2.047,P=0.360).The incidence of pulmonary edema in observation group was slightly lower than that in control group [6.1% (2/33) vs.10.0% (3/30),x2±2.272,P=0.259].The lactic acid levels were decreased gradually along with rehabilitation time,while lactate clearance rate was increased in both groups.At 0 hour and 6 hours after resuscitation,the lactate level (mmol/L) in the observation group was significantly lower than that in control group [0 hour:3.65 ± 2.84 vs.5.72 ± 2.11,t= 1.940,P=0.046; 6 hours:2.12 ± 1.21 vs.4.09 ± 1.45,t=2.892,P=0.005],while the lactate clearance rate was significantly increased compared with control group [0 hour:(0.38 ± 0.15)% vs.(0.18 ± 0.09)%,t=1.447,P=0.018; 6 hours:(0.62 ± 0.14)% vs.(0.51 ± 0.11)%,t=1.920,P=0.047].However,at 12 hours after resuscitation,there were no statistically significant differences in the lactic acid level (mmol/L:1.46 ± 0.39 vs.1.54 ± 1.90,t=0.450,P=0.072) and the lactate clearance rate [(0.78 ± 0.19) % vs.(0.77 ± 0.18) %,t =0.091,P=0.928] between observation group and control group.Conclusion Albumin resuscitation in children with septic shock can stabilize hemodynamics earlier,reduce the incidence of pulmonary edema,and improve the successful rescue rate of refractory septic shock.

Objective To investigate the relationship between gene polymorphism of factor VII R353Q (FVII R353Q) and cerebral palsy for Han Chinese children. Methods Polymerase chain reaction-restricted fragment length polymorphism were used to determine genotype and allele of R353Q gene in 160 children with cerebral palsy and 137 normal children. Results The genotype of FVII R353Q is close to Hardy-Weinberg equilibrium in both CP group and control group (P>0.05). There was not significant difference in the distribution of the allelic frequency and genotype of FVII R353Q between the both groups (P=0.436, P=0.182, respectively). Conclusion The gene polymorphism of FVII R353Q is not significantly related with cerebral palsy for Han Chinese children.
