0.05). Conclusion: There is surface potential in teeth and the potent ial can be affected by the electrolyte surroundings.

objectives To explore the clinical significance of the triple screening method and fetal sonographic markers in Down syndrome screening. Methods The retrospective study included maternal blood serum triple-marker screening per-formed in normal singleton pregnancies at 14+1 to 19+6 weeks and ultrasonography screening for fetal chromosomal trisomy at 18+1 to 23+6 weeks from 2010 to 2013. Results In 24 368 pregancies, Karyotype analysis reveal 35 Down syndromes, the incidence is 0.14%(35/24 368). 25/35 were pregnancies with an expected date of delivery lower than 35 years old and 10/35 were pregnan-cies with an expected date of delivery higher than 35 years old. In 1 215 pregnancies, second-trimester serum screening showed high risk (cutoff>1:380), 14 were confirmed as Down syndromes ( sensitivity 40%;specificity 95.06%). In 1 142 pregnant women showed ultrasonography abnormalities, of which 11 were found to have Down syndrome (sensitivity 60%;specificity 91.09%). In 112 pregnancies, second-trimester serum screening and ultrasonography showed high risk, 4 were conformed as Down syn-drome (sensitivity 11.43%;specificity 99.56). Conclusions The most effective method of screening for Down syndrome is by maternal serum biochemistry. Ultrasonography is important in screening fetal trisomy 21. combined screening methods can improve the detection rate of trisomy 21.

Objective A large number of traditional Chinese medicine(TCM)are widely used for the treatment of patients with cerebral hemorrhage in China. The aim of this study is to systematically review the existing clinical evidences on TCM treatment for cerebral hemorrhage. Methods Randomized controlled trails(RCTs) of TCM treatment of cerebral hemorrhage were identified, eligible studies were included, the methodological quality of inclusive trails was assessed by the modified Jadad scale. The Cochrane Collaberation’s Revman 5.20 was used for data analysis. Results 69 RCTs were available and included. Meta-analysis indicated that relative risk of overall effective rate of Sanqi, Ciwujia, Chuanxiongqin and Naoxueshu were significant difference; SMD(95% CI) of neural function defect score was SMD=-0.46, 95%CI(-0.56,-0.35)of Sanqi, Danshen, Qingkailing, Liangxuetongyufang;SMD(95%CI) of the reduce of cerebral hemorrhage was SMD = -0.98, 95% CI(-1.32, -0.63)of Danshen, Dahuang, Ciwujia, Qingkailing, Liangxue-Tongyufang. Conclusions The evidence currently available showed that the TCM which included do not increase the death rate and adverse reaction of the patients with cerebral hemorrhage, TCM could reduce neurological deficit and improve the absorption of hematoma.

OBJECTIVE: To establish a weighted least square method for the accelerated degradation analysis of protein-type biological standard substances.METHODS: A mathematical model was proposed to estimate the parameters of degradation rate constants k at the elevated temperatures based on the Arrhenius or Eyring equation and chemical reaction principles under the suitable assumptions. Hence, it is probably to predict the stability of biological standard at the normal condition by solving the model.RESULTS: According to the experimental data of recombinant human granulocyte colony-stimulating factor and interferon α-2a, the preliminary numerical experiments were also performed and the results confirm the reliability of the method in the paper.CONCLUSION: The same methodology may be applied in the pharmaceutical industry where it is necessary to predict the viable shelf-life of biological products.

ObjectiveTo summarize the clinical features and risk factors of neonatal clavicle fracture so as to decrease the incidence of this disease.MethodsA total of 85 cases of neonatal clavicle fracture admitted to the Gynecology and Obstetrics Hospital of Fudan University between January 1, 2013 and December 31, 2015 were enrolled in this study. The full-term neonates with natural delivery by the same midwives or doctors on the same day were selected as control group with 1∶1 matched. Clinical features and risk factors of neonatal clavicle fracture based on three factors: mother factors, labor factors and neonatal factors, were analyzed retrospectively. Two independent samplest-test, rank sum test andChi-square test were used for statistical analysis.ResultsThe incidence rate of neonatal clavicle fractures was 0.14% (85/59 991). There were 45 (53%) males and 40 (47%) females; 80 (94%) cases of vaginal delivery, and 5 (6%) cases of cesarean section. According to the relationship between the location of the fracture and the position of the fetus, the fracture occurred in the anterior shoulder in 65 cases (76%) and in the posterior shoulder in 20 cases (24%);and 18 cases (21%) were in the left and 67 cases (79%) in the right. Fifty-five cases (65%) were diagnosed by physical examination, and 30 cases (35%) by X-ray. Two patients (2%) were complicated with brachial plexus injury. Twenty cases (24%) were diagnosed on the day of birth, 32 cases (38%) on the second day after birth, 16 (19%) on the third day, and four (5%) on the 4-6 days. Thirteen (15%) cases were diagnosed in the outpatient department 42 days after birth. All the fractures were cured without special treatment. Compared with the control group, the birth weight of fracture group was significantly higher [(3 646±361) vs (3 447±409) g,t=2.339], and the ratio of the cases complicated with shoulder dystocia was also higher [15% (13/85) vs 2% (2/85),χ2=9.524] (bothP<0.05). The differences in the factors of maternal age, parity, times of pregnancy, gestational age, forceps delivery, time of the second stage of labor and fetal distress between the two groups were not statistically significant.ConclusionsNeonatal clavicle fracture is related to birth weight and shoulder dystocia. Not all fractures can be diagnosed through physical examination on the day of birth, therefore, daily routine physical examinations after birth are necessary. The prognosis of neonatal clavicle fracture is good.

Objective Norwood StageⅠis the standard procedure to cope with hypoplastic left heart syndrome(HLHS), which continues to be the most challenging congenital heart disease .The aim of this study is to retrospectively analyse the perio-perative management of Norwood StageⅠ.Methods Between June 2010 and August 2014, totally 5 small infants with HLHS underwent the standard Norwood StageⅠprocedure.They were all boys.Age at surgeries ranged from 29 to 75 days, and weight from 2.57-3.50 kg with median of 3.13 kg.Case 1, 2 and 3 received standard medical regimen after accessing NICU, which included intravenous prostaglandin E1 and mechanical ventilation.The 3 infants underwent emergent operations because of unstable hemodynamics.Case 4 and 5 received no medical intervention before the urgent surgeries.All 5 cases underwent the standard Norwood StageⅠprocedure under deep hypothermic circulatory arrest, including 4 cases of modified Blalock-Taus-sig shunt( MBTS) and 1 case of Sano shunt.Results The case with Sano shunt died from severe hypoxemia and persistent aci-dosis 32 hours after the operation, another case died from low cardiac output syndrome after cardiopulmonary bypass.The first case underwent bidirectional Glenn procedure 12 months after Norwood Stage I, the postoperative heart function was NYHA I and the oxygen saturation was 0.90-0.95 in room air, but he died from accidental brain injury 3 months after stage Ⅱ.The second case was followed up 3 months after stage I procedure with NYHA I and oxygen saturation of 0.78-0.83 in room air, and lost the follow-up after.The fifth case was followed up 3 months after stageⅠprocedure with NYHAⅠ, confluent MBTS and oxygen saturation of 0.84, the patient is being followed up and waiting for further evaluation for stageⅡprocedures.Con-clusion The standard Norwood StageⅠprocedure is a complex procedure, which demands multidisplinary cooperation, to pal-liatively correct HLHS .Sharing expericences on perioperative managements of Norwood Stage I between heart centers in China will be helpful to decrease the mortality and morbidity in relatively short period .

The neurovascular unit (NVU) consists of neurons,gllal cells and microvessels,etc.There were complex interactions among the various cellular components,which form as a uniform entirety preferably.Anong the various cellular components of NVU,the signal transduction occurred disorders during cerebral ischemia,resulting in neuronal and extracellular ratrix destruction,and thus occurring cerebral infarction and hemorrhagic transformation.Therefore,the treatment of ischemic sttroke should be based on the protection of the overall function of NVU.This article describes the changes and protection of NVU after cerebral ischemia.

Heparanase (Hpa) is the only β-D-glucuronidase of degading heparan sulfate proteoglycans in the body of mammalian.Studies have confirmed that Hpa accelerates angiogenesis in multiple physiopathological processes; however there are still a few studies about the expression and role of Hpa after cerebral ischemia.This article mainly introduces the relation between Hpa and angiogenesis after cerebral ischemia.
