Congenital vahular aortic stenosis (AS),which refers to a congenital malformation of the aortic valve,is the most common causes of left ventricular outflow tract obstruction in chiidren.In 1983,percutaneous balloon aortic valvuloplasty (PBAV) was firstly described as the treatment for congenital AS in children.Over the past 30 years advancement in technique and equipment had radically improved the safety and outcome of balloon valvuloplasty of aortic valve.Nowadays the technique is widely regarded as the therapy of first choice for children with congenital AS.However,it is essential to make decisions about treatment and define which approach has the best chance of success for any given patient before the initial intervention,especially for the neonate with critical AS.PBAV is usually effective for acutely relieving left ventricular outflow obstruction and has excellent short term results in most childen with congenital AS.The mid-and long-trem outcome after a successful balloon dilation of congenital AS in childhood is also good,but late restenosis and valve regurgitation eventually necessitate reintervention in the majority of children,which included aortic valve replacement.PBAV was found to have a high incidence of complications and remains one of the most challenging procedures in the inttcventional therapy of congenital heart disease.Operators should not only acquire the necessary manual skills,but also have the ability to make sound clinical judgment and deal with critical events.Owing to its palliative nature of balloon dilation for congenital AS,the follow-up care of patients after procedure is quite important.

Objective To explore the effects of fat on healing of porcine skin wounds so as to provide a new strategy to promote skin wound repair after injury. Methods Forty-eight full-thickness skin wounds were produced on both sides of the back in 6 male minipigs (8 wounds in each animal). These wounds were then randomly divided into 4 groups, i.e. saline control group, fat autografting group, fibroblast growth factor (bFGF) treatment group and epidermal growth factor (EGF) treatment group. On day 3, 7, 14 and 21 after wounding, the area and the volume of wounds were measured, and histological examination was performed to evaluate the speed and quality of wound healing in different groups. Results On days 3 and 7, the amount of granulation tissue and vessel density in fat treatment group were significantly more abundant compared with other groups. Wound area and volume in fat treatment wounds were markedly decreased compared with those in other groups (P

Objective To investigate the risk for recurrent thyroid carcinoma.Methods Clinical data of 56 cases of recurrent thyroid carcinoma were retrospectively analyzed and summarized possible causes of relapse.Results Student's test revealed that age,initial operative approach,pathological types,postoperative medication and radionuclide therapy were associated with recurrence (P ＜ 0.05),but gender was not associated with recurrence (P =0.240),and resection of single gland was associated with recurrence (P =0.006),but resection of both gland was not so (P =0.153).Multivariate analysis indicated that initial operative approach was the dependent factors for recurrence(P ＜ 0.05).Conclusion Some patients that prone to recurrence should be strengthened regular follow-up.Standard treatment should be used for The recurrences diagnosed.

AIM: To investigate the effect of testosterone with varied concentrations on the fibr inolysis activity of HUVEC and its mechanism. METHODS: Human umbilical vein endothelial cells (HUVEC) were cul tured as recommended. After confluence, the cultures were treated with testoster one(3 ?10 -10, 3?10 -9, 3?10 -8,3?10 -6, 3?10 -5 m ol/L) , and the control confluent cells were cultured in the same medium witho ut steroid. MTT experiment was repeated for 72 hours to investigate each groups' cell proliferation. The tPA and PAI-1 antigen levels were assayed with ELISA K its. Then with HUVEC incubated in androgen receptor antagonist (flutamide) 3 hou rs previously, the experiment was repeated. RESULTS: Testosterone at physiologic or lower concentrations (3 ?10 -10 to 3?10 -8 mol/L ) stimulated the secretion of tPA by HUVEC (P

Papillary thyroid microcarcinoma (PTMC) is a subtype of papillary thyroid cancer,and there are many debates about its treatments,including extent of thyroidectomy,necessity of prophylactic central-neck nodal dissection,risk-benefit ratio of thyroid-stimulating hormone suppression and indications of observation therapy,et al.The epidemiology and treatment programs of thyroid PTMC were reviewed in this article.

Objective To observe the effect of apolipoprotein E mimetic peptide (ApoE23) on lipopolysaccharide (LPS) levels in plasma and the regulatory role of ApoE23 on low density lipoprotein receptor (LDLR) on liver cells in the septic mice.Methods An ApoE mimetic peptide was designed and referred terminologically as ApoE23 in abbreviation.ApoE23 was synthesized by using solid phase synthesis assay and were refined by using high performance liquid chromatography (HPLC).The peptide was identified and confirmed by using electron spray ionization mass spectrometry and amino acid composition analysis.The C57BL mice infected with Salmonella typhimurium group B were treated with apoE23 injected into tail vein.The plasma LPS levels were measured by using immunoturbidimetry.The LDLR expression and level on liver cells were measured by real time PCR and western blot respectively.Results The plasma LPS levels significantly increased and the liver LDLR expression decreased in the septic mice.ApoE23 treatment markedly reduced the plasma LPS levels and redressed the LDLR down-expressions on liver cells both in mRNA and protein levels compared to the septic mice without ApoE23 treatment.Conclusions The reduction of LPS level after ApoE23 treatment may be associated with the modulation role of ApoE23 in LDLR expression on liver cells,and ApoE23 may be a potential agent against bacterial sepsis as well.One of possible mechanisms was most likely associated with effect of ApoE23 on LDLR expression.

The hospital observed the principles of ensuring medical safety,shared risks and responsibilities in its attempt to build the risk mortgage mechanism in the hospital.The mechanism is characteristic of setting up the scope and standards for the risk mortgage,defining the use and refund cycle of the risk mortgage,along with a series of rewards and penalties.This design aims at minimizing cases of medical disputes (malpractice) for better medical safety.

ObjectiveTo explore the clinical presentation, diagnosis, treatment, and outcome of the Barth syndrome (BTHS).MethodsClinical data were collected and analyzed from 3 patients with conifrmed genetic diagnosis of BTHS from June 2013 to October 2014.ResultsAll of the 3 patients were males and two of them were twins. The main clinical manifes-tations of the 3 patients were cardiomyopathy and heart failure, accompanied by different degrees of trabeculations of the left ventricle. Two of them were diagnosed of left ventricular noncompaction (LVNC). All of the 3 patients presented with motor retardation, muscle weakness, growth delay and signiifcantly increased urinary excretion of 3-methylglutaconic acid (3-MGC). One patient was found to have neutropenia. All 3 patients hadTAZ gene mutations which included a novel missense mutation (c.527A>G, p.H176R) detected in the twins and a known nonsense mutation (c.367C>T, p.R123X) identiifed in the other patient. All of the mutations were inherited from their mothers. During the follow-up, the twins died at 7 months old and 7.5 months old respectively. The other patient was still alive.ConclusionBTHS is one of the causes of cardiomyopathy in children. In the male patients who presented with muscle weakness, neutropenia, and increased urinary excretion of 3-MGC, especially in those com-bined with LVNC, BTHS should be screened.

Objective To investigate mosapride in the treatment of functional dyspepsia(FD) and its effect on proximal stomach and gastric emptying function .Methods One hundred and two patients diagnosed of functional dyspepsia in our hospital were ran‐domly divided into observation group (with treatment of mosapride) and control group(with treatment of domperidone) ,and 51 ca‐ses were in each group .The clinical efficacy was observed ,and the LOGIQ‐GE2000 diagnostic apparatus were used to detect the de‐termination of proximal stomach and gastric emptying function before and after treatment .Results The clinical effective rate of the observation group was 86 .27% ,significantly higher than that of the control group(64 .71% ) .The difference was statistically signif‐icant between them(P<0 .05);proximal gastric scores and rate of fundus gas emptying of the observation group were significantly better than those in the control group (P<0 .05);proximal gastric emptying of the observation group was better than that of the control group after taking medicine(P<0 .05);rate of side effect in observed group was 3 .9% ,which compared with control group showed no significant difference (P>0 .05) .Conclusion Mosapride in treatment of functional dyspepsia is better than domperi‐done ,and it could significantly improve the patient′s proximal stomach and the function of gastric motility .
