ObjectiveTo investigate the plasma endothelin(ET),angiotensin (Ang) Ⅱ levels on middle cerebral artery resistance in hypertension patients.MethodsThe plasma ET and Ang Ⅱ levels were determined in hypertension grade 1 (grade 1 group,40 cases),grade 2 (grade 2 group,40 cases ),grade 3(grade 3 group,40 cases) and healthy adults (control group,50 cases).The systolic velocity and pulsatility index of middle cerebral artery were determined by transcranial Doppler,and 24 h ambulatory blood pressure was monitored.ResultsThe pulsatility index in grade 2 group and grade 3 group was higher than that in control group and grade 1 group (1.23 ±0.22,1.31 ±0.21 vs.0.76 ±0.18,0.78 +0.13)(P＜0.05).The systolic velocity in grade 2 group was higher than that in control group,grade 1 group and grade 3 group [(87.8 ± 11.7) cm/s vs.(60.8 ± 10.6),(63.8 ± 11.8),(49.9 ± 10.8) cm/s](P ＜ 0.05),and in grade 3 group was lower than that in control group,grade 1 group and grade 2 group(P ＜ 0.05 ).The plasma ET,Ang Ⅱ in grade 1,2,3 group was higher than that in control group[(46.83 ± 8.83 ),(55.63 ± 10.28 ),(67.19 ± 10.73)ng/L vs.( 38.94 ± 7.83 ) ng/L and ( 50.23 ± 9.23 ),(64.34 ± 12.23 ),( 79.83 ± 13.43 ) ng/L vs.(41.63 ± 8.76 )ng/L] (P ＜0.05).A increasing trend in the plasma ET and Ang Ⅱ was present with increasing the hypertension grade(P ＜ 0.05 ).The night average systolic pressure,night average diastolic pressure and plasma ET,Ang Ⅱ levels in dipper hypertension patients (60 cases) were lower than those in non-dipper hypertension patients(60 cases) [(121.83 ± 11.83) mm Hg(1 mm Hg =0.133 kPa) vs.(138.84 ± 13.29)mm Hg,(77.23 ± 8.54) mm Hg vs.(86.93 ± 10.34) mm Hg,(48.83 ± 10.14) ng/L vs.(59.83 ± 11.29)ng/L,(55.84 ± 10.83 ) ng/L vs.(72.83 ± 20.29) ng/L,P ＜ 0.05].ConclusionMonitoring plasma ET,Ang Ⅱ levels and ambulatory blood pressure in hypertension patients is helpful in using medicine to improve endothelial function and to promote its dynamic type into a dipper blood pressure in the treatment of patients,thereby to reduce the incidence of hypertension adverse events.

Objective To study the influence of arachidonic acid (AA) on L-type calcium channel in rabbits sin-gle cardiomyocyte and its mechanism of antiarrhythmia. Method The single ventricular cardiomyocyte was isolat-ed by using enzyme dispersion method and whole-cell clamp-patch technique was used to record L-type calcium current.All data were analyzed using ANOVA. Results AA inhibited Ica-L in a concentration-dependent manner. The application of 3 μmol/L, 10 μmol/L and 20 μmol/L arachidonic acid reduced the density of peak Ica-L from (10.79±0.93)pA/pF to (8.99±0.43)pA/pF to (7.60±0.35)pA/pF and to (5.60±0.30)pA/pF, respctive-ly (n=7, P<0. O1 ). The Ica-Lpartially resumed after washout. The AA up-shifted the I-V curves of Ica-L without changes of their shape,peak and reverse potentials. The AA also markedly shifted the inactivation curve to left, and prolonged the recorvery time from inactivation,but did not change the curve of calcium channel activation. Con-clustions By acceleration of L-type calcium channel inactivation and prolongation of recorvery time from inactiva-fion,arachidonic acid can reduce the calcium ion influe and prolong effective refractory period, playing the role of antiarrhythmia.

A? plays a crucial role in Alzheimer's Disease and the soluble A? oligomers have been recognized as the emerging neurotoxins,which ultimately cause memory impairment and neuronal loss through different mechanisms.The development of novel drugs targeting A? oligomers indicates new and promising therapy approaches for AD.The pathological roles as the proximal toxins in AD and the compounds,targeting soluble A? oligomers,which are currently in preclinical and early clinical development,are reviewed.

Structural heart disease includes congenital cardiovascular structural abnormalities, valvular heart disease and cardiomyopathy, which shows the common features of cardiac anatomical structure and hemodynamic abnormalities, especially anatomical abnormalities. Echocardiography, especially three-dimensional (3D) ultrasound, is good at displaying anatomical structure and blood flow abnormalities. As a non-invasive method of examination, it has advantage in the evaluation of such heart diseases. In recent years, the gradual rise of 3D printing technology can make physical printing, and the printed heart model can stereoscopically display abnormal state of heart diseases. Ultrasound combined with 3D printing technology may provide more intuitive and accurate information for the assessment of structural heart disease.

Objective:To describe the clinical results of a one-stage operation for posterior cruciate ligament reconstruction and a posterolateral corner reconstruction of popliteus tendon reconstruction,com-pared with an open popliteofibular ligament reconstruction.Methods:Our study included 33 patients who had undergone posterior cruciate ligament reconstruction with use of an achilles tendon-bone allograft and posterolateral corner reconstruction with arthroscopic anatomical reconstruction of popliteus tendon or open reconstruction of popliteofibular ligament.The patients were assessed for knee instability with use of the dial test at 30°and 90°,together with posterior stress radiography and KT-1000 measurement.Re-sults:The mean time of follow-up was more than 2 years.At the final follow-up evaluation,the tibial posterior translation as measured by stress radiography at 90°of knee flexion,the anterior-posterior trans-lation as measured by KT-1000,and the external rotation of tibia as measured by dial test were reduced postoperatively (P<0.001 )in both groups.Between the two groups,the preoperative tibial posterior translation as measured by stress radiography and the preoperative mean anterior-posterior translation as measured by KT-1000 in the popliteofibular ligament group were a little more than those in the popliteus tendon group (P=0.014,P<0.001).But the other comparisons were not significantly different (P>0.05).The final flexion losses were 3.33°±4.88°and 3.06°±3.38°for the two groups.Conclusion:Combined with posterior cruciate ligament reconstruction,anatomical posterolateral corner reconstruc-tion of the popliteus tendon and open reconstruction of popliteofibular ligament showed similar out-comes.This study demonstrated that both posterolateral corner reconstruction techniques were a reliable alternative method in addressing posterolateral corner and posterior cruciate ligament insufficiency of the knee.

Objective To assess the diagnostic yields of clinical chromosomal microarray ( CMA) testing for patients with neurodevelopmetal disorders ( NDD) , and to characterize the spectrum of pathogenic copy number variation(CNV) in NDD.Methods The study was a cross-sectional study.NDD patients from Shanghai Children′s Medical Center ( SCMC ) from April 2014 to April 2015 were recruited.DNA samples from SCMC cohort were tested on Affymetrix Cytoscan Dx microarray platform.The diagnostic yields of CMA testing were further assessed for the whole NDD cohort and each subgroup.Results A genome-wide genotype-phenotype analysis on a total of 107 NDD cases with CMA testing was conducted.Based on the SCMC clinical cohort, the overall diagnostic yield of CMA testing for NDD patients was 20.6%(22/107). Excluding one case with chromosomal aneuploid, the frequency of non-polymorphic CNVs of the rest NDD cases were 25.5%(27/106).The diagnostic yield for developmental delay/intellectual disorder(DD/ID) and autism spectrum disorder(ASD)were 26.3% (15/57) and 10.2%(4/39) respectively.DD/ID was more likely to be associated with CNV than ASD and attention-deficit/hyperactivity disorder(ADHD).Five recurrent genomic loci were significantly enriched in patients including 1q21.1-q21.2, 15q11.2-q13.1, 22q11.2, 7q11.23 and 17q11.2.Conclusion CNV is an important pathogenesis in NDD.

Objectiye To introduce the surgical technique of arthroscopy assisted anatomical posterolateral corner (PLC) reconstruction,including popliteal ligament,popliteofibular ligament and lateral collateral ligament,and evaluate the results of this technique.Methods From August 2008 to April 2010,34arthroscopic posterior cruciate ligament (PCL) and PLC reconstruction surgeries were performed.The average age of the patients was 34.1 (15-52) years.There were 32 males and 2 females.The average time period from injury to surgery was 10.7 months.All patients were chronic injuries and combined ligament injuries,including PCL and PLC injuries.Some cases had other ligament injury,including 6 patients of anterior cruciate ligament (ACL) injury (17.6%),2 of ACL combined medial cruciate ligament (MCL) injuries (5.9%),and 5 of MCL injuries (14.7%).According to Fanellis classification,for type A posterolateral rotation instability,we performed arthroscopic popliteal ligament reconstruction or popliteal ligament combined popliteofibular ligament reconstruction.For type C posterolateral instability,we performed arthroscopic PLC anatomical reconstruction.Results During the follow-up period,14 patients had undergone a second look arthroscopic examination and removal of hardware.The average follow-up time was 18.5 months (13-25 months).At the final follow-up,physical examination,stability evaluation with KT-1000 and Telos stress view,and dial test were performed.The posterior displacement of the knee had decreased from 15.56 mm preoperatively to 5.16mm postoperatively.The external rotation instability had decreased from 14.92° preoperatively to -0.22°postoperatively.The average limitation of knee flexion was 4.23° and no knee extension was limited.Conclusion With the surgical technique of arthroscopy assisted anatomical PLC reconstruction,we can restore the external rotation stability of knee.This technique can be performed combine with PCL reconstruction.

ObjectiveTo explore the damage of blood vessels in carbon monoxide poisoning patients by hyperbaric oxygen, especially for damage of vein, to understand the factors aggravating inflammatory response, thus work out the homologous protective measures.MethodsFrom January 2006 to January 2008, 80 patients of carbon monoxide poisoning were selected as the observation group. Another 80 patients with other diseases were set as the control group. Two groups both accepted hyperbaric oxygen treatment. The time of angioplerosis was compared between the two groups, besides, pain reaction of the observation group was also observed.ResultsThe time of angioplerosis was significantly different between the two groups, pain sensibility intensified in the observation group compared with that before treatment.ConclusionsHyperbaric therapy is closely related with vascular inflammatory reaction of carbon monoxide poisoning patients. Protective measures should be established in order to prevent further damage of vessel, relieve pain of patients and ensure smooth progress of the treatment.

OBJECTIVETo observe the clinical efficacy and safety of modified Wuzi Yanzong Granule (MWYG) in treating mild cognitive impairment (MCI), and to explore its mechanism.

METHODSForty-four MCI patients were selected referring to the international recognized Peterson's criteria and randomly divided into two groups, the treated group treated with MWYG and the control group treated with Ginkgo leaf extraction, with the course of 3 months for both groups. Changes of memorial quotient (MQ), superoxide dismutase (SOD) activity, malondialdehyde (MDA) content, mitochondrial DNA (mtDNA) deletion rate and acetylcholinesterase (AchE) before and after treatment were observed.

RESULTSAfter treatment, levels of MQ, serum SOD activity increased and serum MDA content, mtDNA deletion rate and AchE decreased in both groups (P < 0.01), but the difference between the two groups was insignificant. No adverse reaction was found in two groups.

CONCLUSIONBoth MWYG and Ginkgo leaf capsule can effectively improve the memorial function of patients with MCI, the therapeutic mechanism is possibly related with the actions in reducing AchE activity, improving free radical metabolism, and alleviating mitochondrial DNA oxidation damage.
