Arrhythmias in children with congenital heart disease may be associated either with the underlying abnormality or result from surgical intervention.The treatment rationale bases on the rapid and accurate diagnosis.As a general rule,risk-benefit analysis of drug therapy should be considered when facing an arrhythmia in a child,due to the negative inotropy.In the last decades,non-pharmacological therapy is progressively used in pediatric population.

OBJECTIVETo explore the clinical effects of anterior corpectomy decompression and titanium mesh bone graft fusion combined with titanium plate fixation in treatting multilevel cervical spondylotic myelopathy.

METHODSThe clinical data of 48 patients with multilevel cervical spondylotic myelopathy underwent surgical operation were retrospectively analyzed from October 2010 to January 2013. There were 37 males and 11 females, aged from 37 to 76 years old with an average of 54.6 years. Thirty-five cases were two-segment lesion, 7 cases were three-segment lesion, 6 cases were four-segment lesion. All the patients were treated by anterior corpectomy decompression and titanium mesh bone graft fusion combined with titanium plate fixation. ROM, JOA, VAS and SF-36 scores were recorded before and after operation(including 3, 6, 12 months after operation and final follow-up). Fusion degree and spinal canal decompression condition were observed by radiographic data.

RESULTSAll patients were followed up from 14 to 48 months, with an average of 27.3 months. At 12 months after surgery, radiographic data showed that all patients obtained bony fusion, spinal canal decompression were sufficient. Preoperative vertebral canal sagittal diameter of the most serious segment were (5.13 +/- 1.32) mm, 12 months after surgery were (9.94 +/- 1.22) mm, there was statistically significance (t=2.463, P=0.014); the degree of vertebral canal decompression were (92.15 +/- 2.35)%. Postoperative ROM, JOA, VAS and SF-36 scores were obviously improved than that of preoperative (P<0.05); there was no statistically significance of ROM, JOA, VAS and SF-36 scores in each time after operation (P>0.05).

CONCLUSIONAnterior corpectomy decompression and titanium mesh bone graft fusion combined with titanium plate fixation can obtain higher fusion rate, complete thoroughly decompression, improvement of clinical symptoms and well safety in treating multilevel cervical spondylotic myelopathy.

Objective:To analyze the levels of immune cytokine in peripheral blood(PB) and the expressions of immune related transcription factors in placenta cytotrophoblast,which in patients with pregnancy-induced hypertension(PIH).And to explore the effect of fetal-maternal immune tolerance on pregnancy-induced hypertension.Methods:50 cases patients with PIH were selected as the observation group,and 40 healthy people were chosen as the control group.Enzyme-linked immunoassay(ELISA) was performed to detect the levels of IFN-γ,IL-4,IL-17 and TGF-β in peripheral blood.Quantitative Real-time PCR(RT-qPCR) and Western blot were used to analyze the mRNA expressions and protein levels of T-bet,GATA-3,RORC and Foxp3 in placenta cytotrophoblast,respectively.Results:①Compared with the control group,the IFN-γ and IL-17 levels in peripheral blood in the observation group were obviously higher and the TGF-β level was greatly lower(P<0.05).There was no significant difference of IL-4 level between the two groups(P>0.05),but the ratios of IFN-γ/ IL-4 and IL-17/TGF-β in the observation group were larger than that in the control group(P<0.05).②Compared with the control group,the mRNA expressios and protein levels of T-bet and RORC in the observation group were increased significantly(P<0.05),but that of GATA-3 and Foxp3 were decreased greatly(P<0.05).Thus,the ratios of T-bet/GATA-3 and RORC/Foxp3 in the observation group were significantly larger than that in the control group(P<0.05).Conclusion:PIH is occurred with the imbalance of Th1/Th2 and Th17/Treg,and it might be associated with the mechanism of fetal-maternal immune tolerance disorder that induced by Th cells.

Objective: To study the diagnosis， treatm ent and outcome of infants in patients with hyperthyroidism in pregnancy. Methods: The levels of T3，T4，TSH，FT3，FT4 in 40 cases of hyperthyroid gravida and control group were measured before delivery, the r oute of delivery and the outcome of infants were studied, and the neonatal thyroid f unctions were evaluated by the levels of T3，T4，TSH in cord serum samples . Results: The levels of T3，T4，FT3，FT4 in non-treatm ent group were higher than that of treatment group and control(P<0.01); an i ncreased rate of forceps and cesarean in hyperthyroid gravida was seen compared with that in control group, about 90%(36/40); the body weights of infants in no n-treatment group were lower than that in treatment and control group. There wa s a case of neonatal hyperthyroidism in non-treatment group. Conclusion : Hyperthyroidism should be diagnosed and treated earlier and there is little side effects on the outcome of infants.

Objective To explore the therapy efficacy of gamma knife on pituitary adenoma based on the changes of MR imagings and hormone levels before and after gamma knife treatment .Methods MR imagings and hormone levels, clinical material were retrospectively analysed on 45 patients(altogether 59 times MR examinations)followed up from 1～28 months. Both plain and enhancement MR scans were performed on each MR examination. Results 59 cases were followed up for 1～28 months . The tumor size shranked in 31 cases (52.5%), no changs in 25 cases (42.4%), increased in 3 cases(5%). Of the 59 cases , intratumoral cyts were observed in 15 cases (25%). Functional pituitary adenomas were followed up in 23 cases. The hormone levels droped in 13 cases (56.5%), the number of hormone levels droped in about the sixth month after gamma knife treatment was 8.6% , in 1 year was 13% and in 2 years was 34.8%. Conclusion Gamma knife can effectively keep the pituitary adenomas from their growing up; avoid the overproduce of functional pituitary adenomas . The treatment effects of gamma knife can be enlarged with the time gone.

Erythropoietin (EPO) is an active glycoprotein synthesized by kidney. The physiological function of regulat?ing the synthesis of erythrocytes by EPO makes it as a clinical drug for treatment of anemia resulted from chronic kidney fail?ure. However, its short biological half-life makes frequent administration, which limits its wide clinical utility since the tough burden and pain on patients. Therefore, the development of EPO derivatives with good efficacy, less adverse reaction and long duration has been a hot spot in the field during several decades. There are currently many different variants of EPO derivatives including erythropoiesis stimulating agents (ESAs) on the market. This article aims to summarize the recent re?search progress in the development of erythropoietin derivatives, specially focusing on EPO mimetic peptides (EMP).

Objective To evaluate the effectiveness and safety of liraglutide for obesity or overweight. Methods Random controlled trials of liraglutide for obesity or overweight were gathered from MEDLINE, EMbase, CENTRAL, CNKI, VIP and WanFang. We screened the retrieved studies according to the inclusion and exclusion criteria, evaluated the quality of included studies, and then performed meta-analyses with The Cochrane Collaboration's Revman 5. 3. 0 software. Results Twelve randomized controlled trials of liraglutide for obesity or overweight were included, in which 11 trials were written in English and one trial in Chinese. The results of meta-analyses showed that the body weight was significantly reduced in the liraglutide group than in placebo, insulin, exenatide and glimepiride groups [RR=-0. 91,95%CI(-1. 01,-0. 81),P<0. 000 01;RR=-2. 88,95%CI(-3. 37,-2. 39),P<0. 000 01; RR=-1. 12,95%CI(-1. 32,-0. 92),P<0. 000 01; RR=0. 45,95%CI(-0. 62,-0. 27),P<0. 000 01]. Moreover, liraglutide had significant effect in decreasing HbA1c and systolic blood pressure of patients with obesity or overweight. Conclusion Liraglutide is effective for controlling body weight of patients with obesity or overweight. But its long-term efficacy still needs to be confirmed by performing more RCTs with high quality, large sample and long term follow-up.

Objective:To investigate the relationship between obesity and chronic periodontitis.Methods:2 1 36 subjects (1 091 males and 1 045 females)were included.Body mass index(BMI)was calculated.Gingival index (GI),tooth pocket probing depth (PD)and attachment loss (AL)were measured at 6 ponint of each tooth according the quartation method.The correlation between obesity and the indexes of periodontitis was studied by Spearman analysis.Results:There was a significant positive correlation of BMI degree with chronic periodontitis;there was no correlation between BMI and GI,PD in men,but BMI was positively correlated with AL,BMI and GI in women.Conclusion:Progress of chronic periodontitis may be related to obesity,the relation is more significant in women.
