ABSTRACT
Objective:To evaluate the efficacy,recurrent risk factors and transferable ratio of treatments with 3 different regiments on children with systematic myasthenia gravis (MG).Methods:The data of 104 children with ocular MG from June 2010 to March 2014 were collected from Department of Pediatric Neurology of Xiangya Hospital and they were retrospectively studied.The patients were divided into 3 groups:a methylprednisolone group (n=44),a prednisone group (n=48) and a bromine pyridostigmine group (n=12).Evaluative system from American MG foundation was used to evaluate the efficacy of treatment and the ratio of ocular MG transformed into systematic MG.Results:The efficacy in the methylprednisolone group was better than that in the prednisone group,and both of them were better than that in the bromine pyridostigmine group (both P＜0.05).Methylprednisolone,prednisone combined with bromine pyridostigmine could reach a better long-term efficacy in children with ocular MG.Early treatment with glucocorticoid could reduce clinical relapse.Conclusion:A treatment with high-dose methylprednisolone pulse can improve early clinical remission in children with ocular MG.However,there is a similar efficacy in the long run of different glucocorticoid therapeutic regiments.A relatively order onset age,infection and thyroid dysfunction are recurrent risk factors in children with ocular MG.
ABSTRACT
Objective SGA and IURG fetuses are important risk factors for metabolic disease in adulthood,but the mechanism is not clear.In this study,Irisin levels in umbilical cord blood of different birth weight and IURG neonates were measured and the relationship between Irisin and neonatal weight,gestational age and other factors was explored.Methods This study was conducted in the cross-sectional study of neonates born in our hospital from 2014 to 2016.Newborns were divided into small-for-gestational age (SGA),greater-than-gestational age (LGA),gestational age (AGA) and newborns with intrauterine growth restriction (IUGR).The levels of irisin in umbilical cord blood of 4 newborns were detected.Results In this study,there were a total of 110 cases of newborns.The mean gestational age and mean birth weight of newborns in the SGA group was lower than that in the other three groups(P =0.000).The mean Irisin levels in the SGA and IUGR groups [54.4(45.6-66.7) ng/ml,53.7 (40.3-62.4) ng/ml] were significantly lower than those in the AGA group [67.7 (53.8-78.1) ng/ml,64.7 (53.6-71.2) ng/ml] (P =0.000).The mean insulin levels in the LGA group [7.54(0.83-58.96)mIU/ml] were significantly higher than those in the AGA group [38.00(34.40-39.30)mIU/ml] and IU-GR [3.86(0.49-16.15)] and SGA [4.19 (0.62-14.42)mIU/ml] (P =0.000).In the present study,the correlation analysis showed that Irisin level in neonatal umbilical cord blood was significantly correlated with neonatal gestational age (r =0.22,P ＜ 0.01),fetal weight (r =0.17,P ＜0.01) and maternal age (r =-0.12,P =0.021).However,only in the LGA group,the level of Irisin in cord blood of neonates was positively correlated with insulin level (r =0.41,P =0.042).Multivariate linear regression analysis revealed that SGA (β =-0.14,P =0.02) and fetal weight (β =0.05,P =0.008) were independent risk factors for neonatal umbilical cord blood Irisin levels.Conclusion There was a positive correlation between irisin level and neonatal umbilical cord blood birth weight.The levels of irisin in the neonates of the SGA and IURG groups were significantly lower than those of the AGA and LGA groups,but irisin levels did not differ between the SGA and IURG groups and between AGA and LGA groups.And irisin levels in the LGA group were positively correlated with insulin levels.Our results also reveal that singleton infants of mothers with preeclampsia had lower cord blood irisin levels compared to infants of mothers without preeclampsia.

ABSTRACT
Objective@#To assess the efficiency and safety of low-dose decitabine in patients with lower-risk myelodysplastic syndrome (MDS) to couple with the clinical significance of MDS-related gene mutations.@*Methods@#This study was done in 4 institutions in Zhejiang Province. A total of 62 newly diagnosed patients with lower-risk MDS were assigned to two groups of decitabine (12 mg·m-2·d-1 for 5 consecutive days) and best supportive care (BSC) . Their bone marrow samples were subject to examinations of MDS-related 15 gene mutations. The primary endpoints were the proportion of patients who achieved overall response (ORR) after at least two cycles and progression-free survival (PFS) , and their relevances to the gene mutations.@*Results@#Of 62 enrolled patients, and 51 cases were included in the final analysis. 16 of 24 patients (66.7%) in decitabine group achieved ORR versus 8 of 27 (29.6%) in BSC group (χ2=6.996, P=0.008) ; PFS prolongation of decitabine versus BSC was statistically significant (not reached vs 13.7 months, P=0.037) . Among 51 patients, at least one gene mutation was identified in 20 patients (39.2%) , including 4 single SF3B1 mutation. PFS in cases with gene mutations (not including single SF3B1 mutation) was significantly shorter than of no gene mutation (9.2 months vs 18.5 months, P=0.008) , but not for ORR (37.5% vs 58.1%, P=0.181) . Among 16 patients with mutated genes, ORR in decitabine and BSC groups were 75% (6/8) and 0 (0/8) , respectively. The most adverse events in decitabine group were grade 3 to 4 neutropenia (45.8%) and grade 3 to 4 infections (33.3%) .@*Conclusion@#This preliminary study showed that low-dose decitabine produced promising results with an acceptable safety in lower-risk MDS patients, especially for those with mutated genes. Further study targeting poor prognostic lower-risk MDS patients should be warranted.
ABSTRACT
Objective To explore the effects of parent-adolescent conflict and cohesion on relational aggression among junior students.Methods Parent-adolescent Conflict Questionnaires,Parent-adolescent Cohesion Questionnaires,and the Relational Aggression Questionnaires were used in investigating 392 junior students.Results The level of relational aggression of junior students was low (22.52±5.15).There was no differences between relational aggression of male students (22.93± 5.43) and female students (22.00± 4.73) (P＞ 0.05),and of grade 1 students(22.72±5.14)and grade 2 students(22.64±5.67),grade 3 students(21.93±4.22) (P＞0.05).The students' relational aggression showed a significantly positive correlation with frequency and intensity of parent-adolescent conflict(r=0.269,r=0.307,r=0.268,r=0.271,P＜0.01),and negative correlation with father-adolescent cohesion(r=-0.171,P＜0.01).Parent-adolescent cohesion was negative predictor of relational aggression(β=-0.123,P＜0.05),and the intensity of parent-adolescent conflict was positive predictor(β=0.301,P＜0.01).Conclusion Parent-adolescent conflict and cohesion have significant effect on relational aggression among junior students.
ABSTRACT
Objective To analyse the influence of esmolol on plasma N terminal pro-brain natriuretic peptide ( NT-proBNP) , heart-type fatty acid binding protein ( H-FABP) and cardiac function in acute cerebral infarction patients with myocardial enzyme abnormalities.Methods 86 acute cerebral infarction patients with myocardial enzyme abnormalities from September 2010 to July 2014 in our hospital were selected and divided into experimental group and control group randomly (43 cases in each group).All patients were accompanied by myocardial enzyme abnormalities, patients in control group were given basic treatment, while patients in experimental group were given esmolol hydrochloride intravenous injection on the basis of control group.Plasma NT-proBNP, H-FABP levels and cardiac function were analyzed in two groups.Results Myocardial enzyme levels had no significant difference between two groups on admission.Plasma NT-proBNP levels also had no statistical differences after admission hospital of 6 h, 15 h and 3 d , and experimental group was significantly lower than control group ( P<0.05 ) after admission hospital of 5 day and 7 days.H-FABP levels had no statistical differences after admission hospital of 6 h, 15 h, and the experimental group was significantly lower than the control group (P<0.05) after admission hospital of 3, 5, 7 days.Cardiac function with Killip classification showed no significant difference when on admission and after admission hospital of 3 days, and the experimental group was significantly better than control group (P<0.05) after admission hospital of 5, 7 days.Conclusion Acute cerebral infarction patients with myocardial enzyme abnormalities given esmolol on the basic treatments significantly reduce NT-proBNP and HAFBP levels, and improve cardiac function, which is worthy of promotion in clinical applications.
ABSTRACT
<p><b>OBJECTIVE</b>To investigate the relationship between cytogenetic markers with World Health Organization (WHO) classification, disease progress and prognosis in cases with primary myelodysplastic syndromes (MDS).</p><p><b>METHODS</b>298 patients with de novo MDS from the first affiliated hospital of medical school, Zhejiang University were enrolled in the retrospective analysis of WHO classification, karyotype, and prognosis. Follow-up study was also conducted.</p><p><b>RESULTS</b>The WHO classifications at first diagnosis were as follows: refractory cytopenia with unilineage dysplasia (RCUD), 18 cases; refractory anemia with ring sideroblasts (RARS), 8 cases; refractory cytopenia with multiline dysplasia (RCMD), 104 cases; refractory anemia with excess blasts-1, 76 cases; refractory anemia with excess blasts-2, 85 cases; MDS unclassified (MDS-U), 5 cases involved; and single del (5q), 2 cases. 39.6% of MDS patients carried karyotypic abnormalities. Among them, the frequency of numerical abnormalities, structural abnormalities and the existence of composite abnormalities were 45, 31, and 42, respectively. The composite abnormalities were unbalanced translocations and complex chromosomal abnormalities. The incidence of both karyotypic abnormalities and complex chromosomal abnormalities in RAEB group was higher than that in non-RAEB group (P<0. 05). An analysis based on IPSS-R Scoring System showed that advanced risk stratification (except the low-risk group) gradually enhanced the incidence of karyotypic abnormalities (P<0.05). In addition, the probability of evolution to leukemia increased with the higher IPSS-R score (P<0.05). In RAEB group, the cases with +8 chromosome, accounting for 19.5% of karyotypic abnormalities, had worse prognosis than those with normal chromosomes.</p><p><b>CONCLUSION</b>Karyotype was identified with an independent risk factor in MDS patients. Therefore, the information on cytogenetic analysis was critical for diagnosis, prognosis and individual treatment. MDS patients presenting+8 chromosome, an intermediate risk factor, were associated with a poorer outcome compared to cases with normal chromosomes in RAEB group.</p>

Objective: To determine whether education level and occupation are risk factors of vaginitis in pregnant women and to investigate relationship between vaginitis occurrence during pregnancy and perinatal mortality rates. Methods: A total of 319 women of early pregnancy or mid-pregnancy were enrolled. Six specimens were collected from posterior fornix of each pregnant woman and then cultured for identification of Neisseria gonorrhoeae, intestinal bacteria, general bacteria, fungi, mycoplasma, and chlamydia, respectively. Results: The pregnant women in the "elementary school or below" group and the "middle school" group had significantly higher incidences of vaginitis compared with the pregnant women in the groups of "high school", "skill education", and "college or above". The pregnant women in the groups of "Worker", "Government employee", "Company employee", and "Professionals" had significantly lower vaginitis incidences. The women with infections of Neisseria gonorrhoeae, intestinal bacteria, and general bacteria had higher perinatal mortalities [0.063 +/- 0.011, 0.052 +/- 0.012, and 0.017 +/- 0.008, respectively] than women with infections of fungi, mycoplasma, and Chlamydia [0.002 +/- 0.007, 0.003 +/- 0.004, and 0.001 +/- 0.001, respectively]. Conclusions: Education level and occupation are risk factors related to incidences of vaginitis in pregnant women. The bacteria-related vaginitis is a major reason of perinatal mortality
ABSTRACT
Objective To estimate the effect of itermittent subglottic secretions drainage(ISSD)on management of artificial airway to prevent tube-related pulmonary pneumonia.Methods One hundred ICU patients with intubation for artificial airway were divided equally into control and experiment group by random digits table.Both were managed with construction of artificial airway and besides the experiment group received ISSD. The two groups were compared in terms of incidence and occurrence time of catheter-related pneumonia, time for airway opening and ICU stay.Result The incidence and the occurrence time of pneumonia, time for airway opening and ICU stay time in the experiment group were significantly lower or shorter than those in the control group with statistical difference(all P<0.05).Conclusion ISSD is effective in decreasing the incidence of catheter related pneumonia, shortening the occurrence time of catheter related pneumonia and ICU stay time for the patients with artificial airway.
ABSTRACT
Objective Monitoring the thyroid hormone levels in patients before and after renal transplantation to realize the relationship between thyroid hormones and renal function.Methods Fifty-seven patients were subdivided into stabled graft function group (50 cases) and delayed graft function (DGF) group (7 cases).Thirty healthy men served as control group.Serum triiodothyronine (T3),thyroxine (T4),thyroid-stimulating hormone (TSH) and serum creatinine (Scr) were determined respectably before transplantation and on different days after transplantation.Correlations between thyroid hormones and Scr at 10th day after transplantation were analyzed.Results Serum T3 and T4 levels before transplantation in the two groups were significantly lower than those in the control group (P＜0.01).These four parameters levels had no significant difference between stabled graft function group and DGF group (P＞0.05).In stabled graft function group:T3 level was decreased obviously by 30％ in the 1st day after transplantation,which was higher than the others,elevated at the 1st week post-transplantation,reached the normal range.at the 2nd week post-operation,and higher than pre-transplantation (P ＜ 0.01) at 3rd week; T4 revealed a decrease trend after transplantation and was elevated at 10th day post-transplantation,returned to the pre-transplantation level at 3rd week; TSH had slight decrease after operation,and had no significant difference among every period in comparing with pre-transplantation; Scr revealed a decrease trend continuously and returned to the normal level at the 7th day post-transplantation.In DGF group,Hormones levels were obviously decreased as compared with stabled graft function group; T3 reached the normal range at the 3rd week post-transplantation,whereas T4 returned to pre-transplantation levels at the 30th day; TSH had a significant decrease at the 5th day,and began to increase at the 10th day post-operation; Scr retuned to the normal range at the 30th day post-operation.The correlation coefficients between Scr and T3,T4 were 0.546 and 0.423 respectively.Conclusion There is a significant correlation between thyroid hormones and renal function (T3,T4).Monitoring the thyroid hormones,specially T3,can diagnose renal function change.
