ABSTRACT
Objective:To analyze the clinical characteristics and risk factors of juvenile dermatomyositis (JDM) with relapses by comparing clinical features, treatment and disease course among JDM patients with and without relapses.Methods:A retrospective analysis of 102 JDM patients from Children's Hospital of Nanjing Medical University between March 2017 and March 2021 was carried out. Patients were divided into two groups based on whether a JDM relapse had occurred or not. Initial clinical features, laboratory tests and treatment were compared between the two groups. T-test or Mann-Whitney U test was used for measurement data, chi-square test or fisher exact probability was used for count data. The features associated with risk of relapses were analyzed by multivariate logistic regression. Results:Among 102 children with JDM, twenty patients (19.6%) relapsed during drug reduction or after drug withdrawal. The mean duration to the first relapse was 3.24 years (range: 9 months to 7 years). Myositis specific antibodies (MSA) were positive for 8 (40.0%) patients with relapses. With 5 cases were anti-nuclear matrix protein 2 positive, 2 cases were anti-transcription interme-diary factor 1 gamma positive, 1 case was anti-signal recognition particle (SRP) positive, the other 12 cases were MSA negative. By binary logistic regression analysis, we found that peripheral calcinosis [ OR(95% CI)=17.54(1.55, 198.64), P=0.021], and interstitial lung disease [ OR(95% CI)=3.83(1.27, 11.59), P=0.017] were independently related to JDM with relapses. Fifty-three patients (51.9%) received methylpre-dnisolone pulse therapy for initial treatment and 13 (65.0%) patients with relapses received methylprednisolone pulse for initial treatment. There was no significant difference between the two groups ( χ2=1.70 , P=0.193). Tumor necrosis factor alpha antagonist combined with methotrexate (MTX) had achieved good results in clinical treatment in children with relapses. Conclusion:The risk of relapses is high in children with JDM. Calcinosis and interstitial lung disease at disease onset can predict a relapsing disease course. Aggressive treatment is urgently demanded for patients with JDM, especially those with relapses.
ABSTRACT
Objective:To investigate the influence of age on the fresh cycle live birth rate in patients with poor ovarian response in different controlled ovarian hyperstimulation groups.Methods:The clinical data of 3 342 patients in The First Affiliated Hospital of Zhengzhou University from February 2014 to November 2018 were retrospectively collected, including early-follicular phase long-acting gonadotropin-releasing hormone (GnRH) agonist long protocol group (1 375 cases), mid-luteal phase short-acting GnRH agonist long protocol group (1 161 cases) and GnRH antagonist protocol group (806 cases); each group was divided into 4 subgroups according to age: ≤30 years, 31－35 years, 36－40 years and >40 years, the pregnancy outcomes in each age subgroup were analyzed under different controlled ovarian hyperstimulation protocols.Results:In early-follicular phase long-acting GnRH agonist long protocol group, the final live birth rates of each age subgroup were 39.4% (228/579), 36.1% (135/374), 16.6% (48/290) and 3.0% (4/132); in mid-luteal phase short-acting GnRH agonist long protocol group, live birth rates of each age subgroup were 32.1% (99/308), 20.8% (55/264), 13.0% (45/346) and 7.0% (17/243); in GnRH antagonist protocol group, live birth rates of each age subgroup were 22.8% (26/114), 16.3% (25/153), 11.2% (31/278), and 3.8% (10/261); the live birth rate of each group decreased significantly with the increase of age (all P<0.01). When the age≤35 years old, the fresh cycle live birth rate of the early-follicular phase long-acting GnRH agonist long protocol group was significantly better than those of the other two groups (all P<0.01). The multivariate logistic regression analysis of age and live birth rate of the three controlled ovarian hyperstimulation groups showed age was the independent influence factor ( OR=0.898, 95% CI: 0.873-0.916, P<0.01; OR=0.926, 95% CI: 0.890-0.996, P<0.01; OR=0.901, 95% CI: 0.863-0.960, P<0.01). Conclusions:Age is an independent influencing factor for the prediction of fresh cycle live birth rate in low ovarian response patients. No matter which controlled ovarian hyperstimulation protocol is adopted, the final live birth rate decreases significantly with the increase of women′s age. In addition, the early-follicular phase long-acting GnRH agonist long protocol has the highest fresh cycle live birth rate among all controlled ovarian hyperstimulation groups.
ABSTRACT
Objective:To investigate the different effects of different treatment regimens in resistant Kawasaki disease (KD) and to provide evidence for clinical treatment.Methods:Forty-nine inpatient children with resistant KD from July 2017 to June 2019 in Children's Hospital of Nanjing Medical University were enrolled into this study. Treatment and follow-up were still in progress. Rank sum test and χ2/Fisher test were used for statisic. Results:The incidence of resistance in infliximab group was significantly lower than that of intravenous immunoglobulin (IVIG) retreated group ( P<0.05). Sixteen cases were treated with 5 mg/kg infliximab (IFX), and 33 cases received methylprednisolone and an additional dose of IVIG. Nine cases who were resistant to IVIG and methylprednisolone were treated with IFX, 6 patients responded to IFX, 3 of them were treated with cyclosporine. Coronary artery changes were followed up. Coronary artery lesions (CALs) were improved in the IFX group, CALs occurred in 12(36%) patients received IVIG and methylprednisolone, 4 of them were improved( χ2=0.633 , P=0.426). Patients were followed up for 3-24 months, the incidence of CALs persistence was statistically significantly different between the two groups (0 vs 24%, P=0.021]. Conclusion:IFX might be an effective and tolerable treatment for resistant KD.
ABSTRACT
Objective To explore the diagnosis and treatment of five children with tuberculosis with arthritis as the initial manifestation. Methods The clinical features, laboratory tests and imaging manifestation of 5 children with joint tuberculosis were retrospectively analyzed. Results The course of disease was different. All the five patients were males (mean age 8.5 ±2.9 years old) and suffered from articular symptoms as initial feature. Four of them were diagnosed and treated as rheumatoid arthritis by other hospitals for up to three years, two patients have tuberculosis contact history, and another two patients were found with bone destruction, and one patient has pathologic fracture. Conclusions Tuberculosis is easily misdiagnosed as juvenile idiopathic arthritis , which deserves attention from a pediatric rheumatology physician.
ABSTRACT
Objective To analyze the clinical features and laboratory data of 10 patients with macrophage activation syndrome (MAS) complicating systemic onset juvenile idiopathic arthritis (soJIA),which were characterized by acute severe liver injury.Methods Data of 10 patients with soJIA/MAS from Nanjing Children's Hospital were collected retrospectively.The clinical features,laboratory findings,treatment,outcomes and prognosis were analyzed.Results In the total 10 patients,female (6/10) outnumbered male.Their age ranged from 1.5 to 9.5 years old (average 5.2±2.6).The most remarkable clinical manifestations were severe liver injury without systemic features,representing as hepatomegaly (10/10),splenomegaly (2/10) and strikingly increased transaminase (10/10,median:ALT 1 445 U/L,AST 885 U/L).Central nervous system dysfunction and hemorrhages were recorded in 20％ of the patients.Two patients had pulmonary infection.Laboratory data showed that platelet count was less than normal or precaution value (10/10,≤262×10g/L).Hyperferritinaemia (10/10,median:17 329 mg/ml) and soluble CD25 elevation (median:3 140 U/ml) were common in the soJIA/MAS patients.Evidence of macrophage hemophagocytosis was found in 90％ of the patients (9/10) who underwent bone marrow aspiration.Pathological findings of liver biopsy from 1 patient revealed massive infiltration of mononuclear cells in the portal tracts.Nearly all patients (9/10) received intravenous pulse methylprednisolone therapy,combined with cyclosporine A and high-dose intravenous immunoglobulin.Eight patients had good outcome.Only 2 patients were complicated with severe interstitial lung disease during 12-months follow-up.Conclusion MAS should be considered when patients with soJIA represents acute severeliver injury without systemic features combined with other laboratory data.Intravenous pulse methylprednisolone and cyclosporine A therapy may improve the prognosis of soJIA/MAS.

Objective:In vitro fertilization and embryo transplantation in patients with endometrial implantation window phase of natural killer cell ( uNK ) influence on the endometrial microvascular and uterine artery pulsatility index and embryo implantation.Methods:A retrospective analysis of our hospital from January 2009 to July 2013 the implementation of in vitro fertilization and embryo transfer(IVF-ET) clinical data of 37 patients,according to whether the success of pregnancy and at least 2 times for IVF-ET failure into success group(26 cases)and the failure group(11 cases),compared two groups of research object during the window of implantation in the uterus endometrial uNK cell marker CD56+, uterine artery pulsatility index, vascular endothelial marker F8 factor,alpha smooth muscle actin( alpha SMA) and myosin heavy chain( SMM) and the relationship between the expression of difference.Results:Success group based FSH 3.52±0.68(mU/ml),basal antral follicles of 9.44±2.53 compared with the failure group differences were not statistically significant(P>0.05).The successful group of uNK cells of 27.18±5.94(%),MVD 6.79±1.74 (%) ,αSMA 33.72 ±4.19 (%) , SMM 25.19 ±5.83 (%) were significantly higher than the expression rate of IVF-ET assisted reproductive failure group(P0.05).Conclusion:During the window of implantation in the endometrium of natural killer cells and endometrial angiogenesis was significantly associated with successful pregnancy, may have a certain relationship;uterine artery PI and pregnancy outcome successful has no obviously relationshhip.
ABSTRACT
Objective To investigate ectopic pregnancy from embryo transfer (ET)of in-vitro fertilization (IVF) cycle and intracytoplasmic sperm iujection (ICSI) cycle and frozen-thawed (FET) cycle.Methods From Jan.2005 to Dec.2010,a total of 9037 IVF-ET or ICSI-ET cycles and 4034 FET cycles were performed in our reproductive medicine center,Affiliated First Hospital of Zhengzhou University.The incidence of ectopic pregnancy rate was studied in fresh cycles IVF-ET (5998) and ICSI-ET (3039) cycles,and natural FET (2198) and hormone replacement (E-P) FET (1836) cycles.ResultsOf 4034 FET cycles,1090 clinical pregnancies and 26 ectopic pregnancies were observed,the incidence of ectopic pregnancy was 2.38％ (26/1090).Of 9037 fresh cycles,3602 cycles were clinical pregnancy,and 133 cycles were ectopic pregnancy,and the incidence of ectopic pregnancy was 3.69％ (133/3602).The ectopic pregnancy rate in FET cycles was lower than in fresh cycles significantly (P ＜0.05).Of 3039 fresh ICSI-ET cycles,the incidence of ectopic pregnancy was 2.62％ ( 34/1298 ) in 1298 clinical pregnancies.Of 5998 IVF-ET cycles,2304 clinical pregnancies were observed,the incidence of ectopic pregnancy was 4.30％ (99/2304).Ectopic pregnancy rate in the fresh ICSI-ET cycles was lower than that of IVF-ET group significantly (P ＜ 0.01 ).The ectopic pregnancy rate in the natural FET cycles was 1.46％ (8/547),which was significantly lower than 3.31％ ( 18/543 ) in E-P group ( P ＜ 0.05 ).ConclusionsThe incidence of ectopic pregnancy of FET cycles was significantly lower than that of fresh embryo transfer cycles.The application of exogenous sex hormones in assisted reproductive cycles might increase occurrence of ectopic pregnancy.
ABSTRACT
Objective To evaluate the effects on pregnancy outcome of freezing time from oocyte retrieval and thawing method for metaphase Ⅱ human oocytes vitrification. Methods From Mar 2007 to Mar 2009, the clinical outcome of 30 infertile women undergoing vitrified-thawing oocytes of in vitro fertilizationembryo transfer(IVF-ET) in the Reproductive Medical Center of the First Affiliated Hospital of Zhengzhou University was studied retrospectively, including 21 women with double fallopian tube obstruction and 9 women's husband azoospermia. All infertile women were divided into three groups, including 5 cases in group A (freezing between 4 and 5 hours from oocyte retrieval and conventional thawing method), 9 cases in group B (freezing within 2 hours from retrieval and conventional thawing method) and 16 cases in group C (freezing within 2 hours from retrieval and improved thawing method). The vitrified oocytes were preserved for 2 months to I year and thawed for Intracytoplasmic sperm injection (ICSI) and embryo transfer. The outcome of IVF and pregnancy were recorded. Results (1) The rates of oocyte survival was (65±33) % in group B and (72±23)% in group C and the rate of transfer cycle was 9/9 in group B and 16/16 in group C, which were all significantly higher than (16±17) % of oocyte survival and 1/5 of transfer cycle in group A (P = 0. 001,0. 021). However, the rate of oocyte survival and transfer cycle between group B and group C did not reach statistical difference (P > 0. 05). The rate of implantation and clinical pregnancy of (33±38) % and 9/16 in group C were significantly higher (4±11)% and 1/9 in group B (P =0. 033,0. 040).(2)The mean age of women in group C were (28.6±2.1) in oneself oocyte, (28.0±4.6) in donor oocyte and (28.1±3.4) in donor sperm. The rate of oocyte survival was (73±25) %, (88±10) % and (66±25) %. The rate of fertilization rate was (84. 6±0. 9) %, (79. 3±2. 0) % and (82. 8±15.0) %. The rate of implantation was (20. 0±44. 7) %, (33. 0±0. 1) % , (41.6±41.7) %. The rate of clinical pregnancy was 1/5 in oneself cycles,3/3 in donor oocyte cycles, 5/8 banked donor sperm cycles in group C. All above clinical parameters were not statistically different (P >0. 05). (3) In group A, one women underwent IVFET and no clinical pregnancy was observed. One women pregnancy was terminated at two months in group B.The clinical pregnancies rate of group C was 9/16, late abortion occurred in 1 woman, the other 8 women underwent term pregnancy, including 5 male infants and 4 female infants. All of infants showed normal Karyotype. Live-birth rates per warmed oocyte was 5.9% (8/135). The mean gestational weeks and birth weight of the infants were (39. 4±0. 9) weeks and (3574±569) g, respectively. Conclusions Embryo quality and clinical outcome of thawing cycles could be significantly improved when oocyte vitrification was performed within 2 hours from oocyte retrieval and improved thawing method.
ABSTRACT
Objective To investigate the incidence of and clinical factors influencing neonatal birth defects from different assisted reproductive technology. Methods Between October 1998 and December 2006,1271 newborns from mothers treated by in vitro fertilization techniques [ including in vitro fertilization (IVF), intracytoplasmic sperm injection (1CSI) and thaw embryo transfer (Thaw-ET) ] matched with 269 newborns from mothers treated by artificial insemination were enrolled in Reproductive Medicine Center in First Hospital Affiliated to Zhengzhou University. Their medical information was analyzed retrospectively to compared neonatal characteristics, the incidence of birth defect and anomalous organs involved between in vitro fertilization group and artificial insemination group. Results In group of in vitro fertilization, those newborns with low birth weight from IVF, ICSI and Thaw-ET were 20. 0% ( 134/671 ), 22. 4% (92/410), 18.9% (36/190)respectively, which were more than 11.5% (31/269) cases in group of artifical semination with statistical significance (P < 0. 05 ). The rates of multiple pregnancy of 23.8% ( 160/671 ), 25.4% (104/410) ,21.1% (40/190) in subgroup of 1VF, ICSI and Thaw-ET were significantly higher than 10. 0% ( 27/269 ) in group of artifical insemination( P < 0. 05 ). The rate of macrosomia in group of in vitro fertilization was significantly lower than that of artificial insemination group (3.9% vs 8. 2%, P <0.05). However, the incidence of birth defect involved in various organs did not show significant difference between two groups ( P>0.05 ). Conclusions The incidence of multiple pregnancy demonstrated obviously increasing trends born with various In Vitro Fertilization techniques, which pave the way to high risk pregnancy. However, the incidence of newborn birth defect was not increased significantly. Thus, to lower occurrence of multiple pregnancy was the key approach to obtain neonates health.
ABSTRACT
Objective To compare the advantages of three-dimensional(3D) and two-dimensional(2D) ultrasound in embryo transfer. Methods A total of 319 patients accepted embryo transfter were included in this study. 2D and 3D ultrasound were used to investigate the uterine cavity and transfer distance from the fundus (TDF),respectivly. They were divided into four groups according to TDF difference(D-TDF) between 2D and 3D ultrasound(group of DTDF<3mm,group of DTDF3～5mm,group of 6～9 mm,group of DTDF≥10 mm. Pregnancy outcomes among the four groups were compared. Results Of the 319 patients, 41 were observed to have abnormal uterine cavity. For 140 patients, the TDF measured by 2D ultrasound were different from that measured by 3D ultrasound. Clinical pregnancy rate and implantation rate were found lowest in group of TDF≥10 mm mm (7.7% vs 34.1%,38.1% ,40.0% and 3.6% vs 18.2% ,21.2% ,20.0%, P <0.05). Conclusions 2D ultrasound is limit and deficient for embryo transfer, especially for the visualization of uterine cavity and location of catheter tip, however, it may be better achieved with 3D ultrasound. It is helpful to use the 3D ultrasound to place the catheter tip accurately and improve the pregnancy rate of embryo transfer.
ABSTRACT
Objective To evaluate the effectiveness of gamma knife and radioactive effect for glioma.Methods MR images of 106 cases with glioma treated by gamma knife were analysed based on classified.Results The effectiveness of gamma knife was the best for ependyoma and oligodendroglioma,the secondly for astocytoma (Ⅰ～Ⅱ) .The effectiveness for astrocytoma( Ⅲ～Ⅳ)was not well.The effective rate in 1 year after treament for astocytoma(Ⅰ～Ⅱ)was far higher than 2～3 years later.The 2nd year after treatment was the peak time for edema around tumor and the special radioactive contrast enhancement on MR.Conclusion Gamma knife is a effective therapy for glioma,especially for ependyoma,oligodendroglioma and astocytoma(Ⅰ～Ⅱ).The radioactive effect showed as edema and radioactive contrast enhancement on MR can become smaller or disappear 2 years later after treament.
