Objective To establish a clinical prediction model for preeclampsia by monitoring risk rating of MP gestation and levels of placental growth factor(PLGF)combined with uterine artery pulsatility index(PI)measured during examination of fetal nuchal translucency(NT).Methods Twenty-four patients with preeclampsia who met the inclusion criteria were selected as the case group,and 95 healthy pregnant women during the same period were randomly selected as the control group.Serum concentrations of PLGF,uterine artery PI values measured by quantitative immunofluorescence assay at 11-14 weeks of gestation,risk ratings for MP hypertension monitoring at 11-20 weeks of gestation,and other relevant data,BMI,age,gestation,mode of delivery,neonatal birth weight and Apgar score were collected in the two groups.Results Results of univariate regression analysis showed that BMI,age,high risk of PI,MP and PLGF<12 were influencing factors for adverse outcomes.Results of multivariate regression analysis showed that high PI,medium high risk in MP and PLGF<12 were independent risk factors for adverse outcomes.The prediction model of PE established was logit(P)=-15.767 + 0.020×PI + 0.072×MP risk(medium-high risk = 1,low risk = 0)+ 0.181×PLGF classification(＜12 = 1,≥12 = 0),with an AUC area of 0.883,specificity of 0.816 and sensitivity of 0.846.Conclusion The combination of PI,MP risk and PLGF to establish a clinical predictive model for preeclampsia has certain value,and its combined predictive value is higher than that of single application.

Objective To investigate the clinical features and possible pathogenesis of Moyamoya disease combined with hyperthyroidism. Methods The clinical data of 10 cases Moyamoya disease combined with hyperthyroidism were retrospectively analyzed.Results Among 10 patients in this group, 1 patient was male and 9 patients were female.All the patients were presented as ischemic cerebrovascular disease.One patient was diagnosed by DSA, 4 patients was diagnosed by CTA, and 5 patients was diagnosed by MRA.Nine patients had bilateral lesions and 1 patient had unilateral lesions.Conclusions The routine screening of thyroid function should be performed for patients with Moyamoya disease, especially women.And people who affected stroke should test cerebral vascular to early prevention and avoid stroke.

Objective To analyze retrospectively the clinical manifestations,features of the biopsy of skeletal muscle with histochemistry and immunohistochemistry staining of 40 patients with dysferlinopathy and investigate its clinical,pathological diagnostic value.Methods The clinical data,features of the biopsy of skeletal muscle with histochemistry,immunohistochemistry staining of 40 patients with dysferlinopathy were analyzed.Results Chronic progressive weakness and wasting were the general clinical manifestations.In our study,it was divided into three phenotypes according to the involved muscles of dysferlinopathy:27 cases with proximal muscle,12 cases with the gastrocenemius,1 case with the tibialis anterior muscle.The serum creatine kinase levels all had a rise in different degree (134-19 795 U/L).All the patients showed myogenic lesions in electrophysiologic study.12 patients underwent skeletal muscle MRI.Proximal muscle was involved in 4 cases ; gastrocnemius muscle was mainly involved in 7 cases ; and anterior tibial muscle initially was involved in 1 case.All 40 cases showed active muscle fiber degeneration,necrosis and regeneration on muscle pathology.Connective tissues were proliferated and inflammatory cells infiltrated in endomysium,perimysium and perivascular sites of 16 patients.Immunohistochemical staining with anti-dysferlin monoclonal antibody identified the deficiency of dvsferlin in the sarcolemma of 30 cases with dysferlinopathy,and dysferlin was severely reduced in 10 cases.Conclusion Progressive weakness and wasting of skeletal muscle are the clinical manifestations of dysferlinopathy.The early involved muscles determine the clinical phenotype of dysferlinopathy.High serum creatine kinase levels show that dysferlinopathy is a membrane protein null disease.Muscle MRI of lower limbs may reflect the involved muscles,which is essential for clinical phenotypes and selecting muscle biopsy.The pathological characters of dysferlinopathy are changes of muscular dystrophy.Inflammatory cellular infiltration is relatively common in biopsied muscles of many dysferlinopathy patients,and dysferlinopathy needs to be differentiated from inflammatory myopathies.The deficiency or severely decreased dysferlin on the sarcolemma in immunohistochemical staining with anti-dysferlin monoclonal antibody is an important information for diagnosing dysferlinoapthy.
