Objective To study the clinical characteristics and current treatment options of neonatal congenital portosystemic shunt (CPSS).Method A newborn infant diagnosed with CPSS complicated with iliac artery-umbilical vein fistula was studied.CNKI,VIP,WanFang and Pubmed databases were searched using CPSS and Abernethy malformation as keywords.A total of 8 papers on neonatal CPSS were retrieved from 2006 to 2016.Result The case treated in our hospital was a boy with symptom of dyspnea and cyanosis.His ultrasound cardiograph showed pulmonary hypertension,and the heart and abdominal CT scan showed portosystemic shunt,dilated portal vein and umbilical vein,patent ductus venosus (PDV) and iliac artery-umbilical vein fistula.A total of 25 patients were analyzed including our patient and 24 cases reported in 8 papers.Cases of intrahepatic shunt (n =22) were nore common than extrahepatic shunt (n =3),and most cases could be diagnosed with ultrasound.Congenital heart diseases,intrauterine growth retardation,cutaneous hemangioma were common complications of CPSS.Abnormal liver function (52.0％),hyperammonemia (28.0％),pulmonary arterial hypertension (12.0％),dyspnea (12.0％) were common clinical manifestations of neonatal CPSS.Most CPSS cases were treated non-operatively during neonatal periods,and in 40.0％ of cases the shunts were closed spontaneously,but mortality was 20.0％ among previous cases.Conclusion Abnormal hepatic function is the most common clinical symptom of neonatal CPSS.Cases of extrahepatic shunts and complicated with PDV are dangerous and operation should be done as soon as possible,meanwhile complications should be treated appropriately.

Objective To investigate the usefulness of percentage of free prostate specific antigen(FPSA/TPSA)/PSA density[(F/T)/PSAD]in the diagnosis of prostate cancer of PSA level in 4~10ng/ml. Methods 88 patients of PSA level in 4~10ng/ml were carried out transrectal ultrasound guided prostate biopsy. Among them,21 patients were proved to be suffering from prostate cancer,and other 67 patients were identified as benign prostate hypertrophy. The effect of F/T ratio,PSAD and(F/T)/PSAD in the diagnosis of prostate cancer were investigated. Results The mean value of(F/T)/PSAD of prostate cancer were significantly lower than benign prostate hypertrophy for patients with PSA levels in 4.0-10ng/ml, This difference has arrived statistical significance(P

BACKGROUND: The human homograft valve has been widely used in the operation of the valve replacement and congenital heart disease. However, reports concerning pulmonary valve biomechanical suitability as a long-term substitute for aortic valve are limited.OBJECTIVE: To compare the biomechanical properties between human aortic and pulmonary valves conserved with ultra low temperature in liquid nitrogen.METHODS: A contrast observation trial was conducted in the laboratory of Congenital Heart Disease of Fuwai Hospital from March to July in 2004. Six samples of heart aorta valves and pulmonary valves were collected from the cadaveric heart within 6 hours, and the experimental procedure was disposed according to ethical criteria. The biomechanical properties of the circumferential direction of the valve were investigated using uniaxial tensile tests. The thickness of the valve was measured by HD-10 thickness instruments.RESULTS AND CONCLUSIONS: Compared to human aortic valves, the thickness of the human pulmonary valves was thinner significantly, but the stress-strain, tensile strength and the maximum tangent modulus E (the slope of linear segment) in the curve had no significant difference (P> 0.05). Biomechanical differences between the aortic and pulmonary valve are minimal, in respect, pulmonary valve can be considered biomechanically suitable for aortic valve replacement.

Objective To investigate the effects of medicine androgen deprivation therapy(ADT)on quality of life in patients with prostate cancer.Methods A total of 42 consecutive advanced prostate cancer patients without any other anti-androgen medications after ADT[A subcutaneous depot injection of LHRH-agonist(Zoladex) was instituted every 28 days]were enrolled.Levels of serum testosterone and prostatic specific antigen(PSA)were obtained just prior to ADT and after ADT.The general and disease-specific health-related quality of life were assessed.Results The average testosterone level was less than 50 mg/L after medical ADT in 3 weeks.And PSA level declined dramatically in one month.Although there were no significant differences on physical discomfort and limitations to daily activities.Urinary obstruction symptoms after ADT were disappeared and the size of prostate were reduced after one month.The appetite and vigor were worsened.Overall health status and sexual function were significantly reduced.Conclusion The ADT could make serum testosterone and PSA decline dramatically in short time,and worsen some general health-related quality of life.

Objective: To screen and identify serum amyloid A (SAA) in patients with prostate cancer with mass spectrum technique. Methods: SELDI technology was used to detect the changes in protein expression. SAA was screened and separated and then identified by peptide mass fingerprint (PMF) based on matrix-as-sisted laser desorption/ionization time of flight mass spectrometry (MALDI-TOF-MS) and database searching. Results: The analysis showed that a mass cluster in the ranges of 11.1-11.9KD in M/Z value in the serum of prostate cancer patients was much higher than that in the control group. Meanwhile, this protein peak was closely correlated with clinical stages of prostate cancer. The level of the protein peak was increased as the illness got serious. Through MALDI technology combined with HPLC, the mass cluster in the range of 11.1-11.9KD in M/Z value on the chip was identified as SAA. And it was also verified through ELISA method. Conclusion: Mass spectrum technology is an effective method to detect the biological markers in prostate cancer patients. This method is convenient, highly sensitive and with good reproducibility. The SAA can be used as a marker in the diagnosis of prostate cancer. These indices are also meaningful in screening and identifying signal proteins from the serum of prostate cancer patients.

Objective To explore the influence of early rapidly increased amino acid dosaging on the nitrogen balance and growth in preterm infants.Methods A total of 37 prematures admitted to our NICU within 24 hours after birth and with birth weight of 1 000 g to 1 800 g from November 2011 to January 2013 were randomly divided into study group (n =18) and control group (n =19).Parenteral nutrition (PE) was provided in both groups within 24 hours after birth.The starting amino acid dose was 1.5g/kg per day,then rose by 1 g/kg per day in study group and by 0.5 g/kg per day in control group,until to maximum of 3.5 g/kg per day.The dosage of lipids,glucose,and electrolytes in parenteral nutrition was provided routinely.The trial was double-blinded.Results In the first 5 days of PE,the nitrogen balance had no significant difference between these two groups (F =0.025,P =0.652) ; however,the time of regaining birth weight was significantly shorter in study group [(7.23±2.48) d] than in control group [(9.42±2.03) d] (t=-2.090,P=0.044).There were no differences between these two groups in trems of completely feeding time,weight gain rate,head circumference growth rate,length of hospital stay,and hospital costs (all P ＞ 0.05).Meanwhile,the rates of neonatal necrotizing enterocolitis,sepsis,mechanical ventilation administration,and damage of hepatic and renal function were also not significantly different.The administration of different dosages of amino acids did not affect the energy intake in both groups (F =1.893,P =0.218).Conclusions Prematures need early amino acid administration,with a starting dosage of more than 1.5 g/(kg · d).Rapid increase of amino acid dosing will not affect early nitrogen balance in premature infants; meanwhile,it contributes to weight gain without increasing the complications and hospitalization costs.
