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.

0.05). In contrast,caspase-3 was strongly expressed in the acinar and ductal epithelial cells in SS. Significant difference was found in caspase-3 expression between SS patients and control group (P

Objective To observe the expression of nuclear factor-kappa B(NF-κ3)and monocyte chemnattractant protein-1(MCP-1),and the infiltration of mononuclear macrophage CD68 in lupus nephritis (LN).The association between NF-κB,MCP-1 and MΦ with kidney pathology and clinical manifestations is explored.MethodsNF-κB,MCP-1 and MΦ in renal biopsy specimens from 49 cases of LN were detected using immunohistochemical techeniques.Forty-nine cases of renal tissues were examined for NF-κB by in situ hybridization.The relationship between NF-κB,MCP-1 and MΦ with kidney pathology and clinical manifestations were analyzed.Results ①Compared with the control group ,the expression of NF-κB,MCP-1 and MΦ in LN was significantly higher(P＜0.01).The expression of MCP-1 positively correlated with MΦinfiltration and NF-κB(P＜0.01)in glomeruli and renal tubule and renal interstitium of LN.The expression of NF-κB,MCP-1 and the infiltration of MΦ in LN Ⅳ was significandy higher than non LN Ⅳ and the control group(P＜0.01,P＜0.05).There was no significant difference between renal NF-κB positive group and negative groups in the degree of the immunohistochemical and in situ hybridization examination(P＞0.05).②The histological activity index,urine protein volume(24 h)and serum creatinine in LN were significantly higher than the control group(P＜0.01),and the expression of NF-κB in LN was correlated with histological activity index,urine protein volume(24 h)and serum creatinine(P＜0.01,P＜0.01,P＜0.05).MCP-1 and CD68 expression in LN were correlated with histological activity index and urine protein volume(24 h),but not correlated with serum creatinine(P＞0.05).Conclusion NF-κB induced MΦ by activating MCP-1 may be one cause of kidney injury of LN.NF-κB signal pathway may act as a new therapeutic target for MΦinfiltration and proliferation inhibition in kidney.

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.

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 evaluate the accuracy in placement of cervical anterior transpedicular screws (ATPS) under the guidance of our modified drilling template.Methods Eight wet cadaveric specimens of adult cervical spine,4 male and 4 female ones,were used for this experiment.Data of CT thin layer scanning of the cervical specimens in DICOM format were imported into software Mimics 17.0.After 3D models of the cervical vertebrae were reconstructed,the optimal trajectory was designed for ATPS placement in the transparent mode of the 3D models.Normal and our modified drilling templates for ATPS placement were designed and manufactured by 3D printing.The 2 kinds of drilling templates were used to assist ATPS placement onto one cervical vertebra,with laterality randomized.Altogether 64 pieces of ATPS were placed,with 32 ones for each drilling template.Postoperative CT scanning was conducted to evaluate the accuracy in ATPS placement.The 2 kinds of ATPS template were compared in terms of the deviations between actual and ideal trajectories in direction (caudal-angle and extroversive-angle) and position (X and Y axes) of the entry point.Results Our modified drilling template led to one screw penetrating the pedicle cortical bone while the normal drilling template led to 4 screws penetrating the pedicle cortical bone,yielding an accuracy rate of 96.9％ and of 87.5％ respectively.The extroversive-angle deviation (0.72°±0.69°),caudal-angle deviation (0.91°±0.70°),X axis shift (0.53 ±0.40 mm) and Y axis shift (0.54 ±0.42 mm) related to the modified template were all significantly smaller than those related to the normal template (1.16° ± 0.70°,1.49°±0.68°,0.88±0.40mm,1.22±0.42mm,respectively) (P ＜0.05).Conclusion Compared with a normal ATPS template,our modified drilling template for ATPS may be advantageous in better fitness,greater stability,increased accuracy in screw placement,and protection of adjacent discs.

Objective:To explore the effectiveness, safety and cost between urinary follicle stimulating hormone (uFSH) and recombinant follicle stimulating hormone (rFSH) in controlled ovarian stimulation (COS) in China.Methods:Data were collected from 16 reproductive centers in China covering oocytes collection time from May 1, 2015 to June 30, 2018. Eligible patients were over 18 years old, adopting COS with uFSH (uFSH group) or rFSH (rFSH group) as start gonadotropins (Gn), and using in vitro fertilization (IVF) and (or) intracytoplasmic sperm injection for fertilisation, excluding frozen embryo recovery cycle. Generalised estimating equation was used to address the violation of independency assumption between cycles due to multiple IVF cycles for one person and clustering nature of cycles carried out within one center. Controlling variables included age, body mass index, anti-Müllerian hormone level, cause of infertility, ovulation protocol, type of fertilisation, number of embryos transferred, number of days of Gn use.Results:Totally 102 061 cycles met eligibility criteria and were included in the analyses. In terms of effectiveness, after controlling relevant unbalanced baseline characteristics, compared with rFSH group, the high oocyte retrieval (>15 oocytes was considered high retrieval) rate of uFSH group significantly decreased in gonadotropin-releasing hormone agonist protocol ( OR=0.642, P<0.01) and in gonadotropin-releasing hormone antagonist protocol ( OR=0.556, P=0.001), but the clinical pregnancy rate per transfer cycle and the live birth rate per transfer cycle significantly increased ( OR=1.179, OR=1.169, both P<0.01) in both agonist and antagonist protocols. For safety, multiple analysis result demonstrated that in the agonist protocol, compared with rFSH group, the incidence of moderate to severe ovarian hyperstimulation syndrome of uFSH group significantly decreased ( OR=0.644, P=0.002). The differences in ectopic pregnancy rate and multiple pregnancy rate between the uFSH and rFSH groups were not significant ( P=0.890, P=0.470) in all patients. In terms of cost, compared with rFSH group, the uFSH group had lower total Gn costs for each patient ( P<0.01). Conclusion:For patients who underwent COS, uFSH has better safety, and economic profiles over rFSH in China.

OBJECTIVETo observe the effects of micro-invasive embedding combined with montelukast sodium and simple montelukast sodium for children cough variant asthma (CVA).

METHODSA total of 240 patients were randomly assigned into an observation group and a control group, 120 cases in each one. Considering of cases dropping, 101 patients in the observation group and 105 cases in the control group were included. Montelukast sodium chewable tablets were applied before sleep for 3 months in the control group, 5 mg a time, once a day. Based on the treatment as the control group, micro-invasive embedding was used for 3 months in the observation group, twice in the first month and once in the other two months. The acupoints were Feishu (BL 13), Danzhong (CV 17), Dingchuan (EX-B 1), and Zusanli (ST 36). Follow-up was conducted 9 months after treatment in the two groups. The cough score, serum immunoglobulin (IgE, IgG, IgA), platelet activating factor (PAF) were observed before and after treatment. The indices were compared before and after treatment and at follow-up, including pulmonary function indices[peak expiratory flow rate (PEF), forced expiratory volume at the 1st second (FEV1)], and small airway function indices[forced expiratory flow rate with remaining 25% vital capacity (MEF25%), forced expiratory flow rate with remaining 50% vital capacity (MEF50%), forced expiratory flow rate with remaining 75% vital capacity (MEF75%) and mid expiratory flow rate (MEF25%-75%)]. Also, the total effects were evaluated.

RESULTS①The total effective rate in the observation group was 93.1% (94/101), which was better than 87.6% (92/105) in the control group (<0.05). The cough disappearance time of the cured children in the observation group was (10.38±2.64) d, and it was shorter than (10.72 ±2.60) d of those in the control group (<0.05). After treatment, the cough score apparently decreased compared with those before treatment in the two groups (both<0.05), with better result in the observation group (<0.05). At follow-up, the recurrence frequency of the observation group was (1.43±1.20), and it was less than (1.91±1.71) in the control group (<0.05). ②The levels of serum IgA and IgG after treatment in the two groups increased, and those of serum IgE and PAF decreased, compared with those before treatment. There was statistically significance except IgG in the control group before and after treatment (all<0.05), with better Results in the observation group after treatment (all<0.05). ③ Compared with those before treatment, all the pulmonary function indices were improved obviously after treatment and at follow-up in the two groups (all<0.05), without statistically significance between the two groups (both>0.05). ④ There was no statistically significance before and after treatment on small airway function indices in the two groups (all>0.05). The indices at follow-up increased compared with those before treatment in the two groups (all<0.05), with better Results in the observation group (all<0.05).

CONCLUSIONSMicro-invasive embedding combined with montelukast sodium achieved de-finite effect for children CVA, which can improve the body's immune and microcirculation. The effect is better than that of simple montelukast sodium on improving small airway function, etc.
