Objective To investigate the correlation between the growth rate, thyroid function in the first month and neurodevelopmental outcome at the age of 2 in the infants of the maternal thyroid disease. Methods We chose 156 infants of maternal thyroid disease from January 2013 to December 2014 born in our hospital as the experimental group and 150 normal infants of their mothers without high risk factors during pregnancy as the control group. We observed the rate of weight, length and head circumference growth in the first month and TT4 、TSH level at the 1^st day, 7^th day, and 28^th day after birth. We followed up two groups every 3 months up to the age of 2. We assessed Bailey mental development index (MDI) and psychomotor development index (PDI) at the age of 2. Regression analysis was used to test the correlation between the growth rate, TT4,TSH level in the 1^st month and MDI, PDI at the age of 2. Results ① The rate of growth rate in the 1^st month of the experimental group was slower than the control group. It was statistically significant difference between the two groups (P<0.05); ②MDI, PDI at the age of 2 in the experimental group were lower than those of the control group. It was statistically significant difference between the two groups (P<0.05); ③The rate of growth rate in the first month of the experimental group was positively related to MDI and PDI at the age of 2.④The difference between the level of TT4,TSH at the 1^st day, 7thday, and 28^th day and the median after birth was negatively related to MDI and PDI at the age of 2. Conclusion The maternal thyroid disease will affect the first month growth rate and neurodevelopmental outcome at the age of 2 of their infants. Their infants will grow behind than the normal newborns on pregnancy without high-risk disease.The growth rate of the first month and the level of T4 and TSH on the 1^st day, 7^th day, and 28^th day in maternal thyroid disease are closely related MDI and PDI at the age of 2.

Objective To investigate two different doses atropine make reverse effects on the function of sinus node and the atrioventricular node inhibiting action dexmedetomidine (Dex). Methods 20 healthy volunteers were included in the clinical trials aged 18~30 years (12 male, 8 female). The volunteers were administered with Dex at loading dose 1.5±0.5 μg/kg and then at 0.75±0.25 μg/(kg·h). During the trail, the volunteers who happened the minimal heart rate less than 50±5 bpm, atrioventricular node forward 2∶1 block point less than 150 bpm needed to randomly accept 0.5 mg(group A₁)or 1 mg(group A₂)atropine to antagonize(n=10). SNRT, CSNRT, AVN 2∶1 block point and AVNERP were recorded through TELAP. Results Intra-group comparison indicated functional parameters of SN and AVN were inhibited by Dexsat T₁. SNRT were prolonged (P<0.05), AVN 2∶1 block point were decreased (P<0.05),AVNERP were prolonged at T₁ compared with T₀(P<0.05). All indexes in group A₁ and AVNERP in group A₂ were back to basal level after using atropine at T₂(P<0.05). SNRT, CSNRT were shorted at T₂ compared with T₀ in group A₂(P<0.05). AVN 2∶1 block point had more increased at T₂ compared with T₀ in group A2(P<0.05). Inter-group comparison indicated no significant differences in functional parameters of SN、AVN at T₀(P>0.05). SNRT, AVNERP were shorted at T₂ in group A₂ compared with group A₁. AVN 2∶1 block point were increased at T2 in group A₂ compared with group A₁. Conclusion 0.5 mg atropine may reverse the function of SN and AVN that are inhibited by Dex. 1 mg atropine may increase functions of SN and AVN that are inhibited by Dex.

Objective To evaluate the left ventricular regional systolic function before and after left anterior descending coronary artery stent implantation (PCI) using three-dimensional speckle tracking imaging (3D-STI) in patients with coronary artery disease. Methods 30 patients who received left anterior descending PCl were underwent routine and three-dimensional echocardiography before and after 3~5 days, 3 months to obtain longitudinal strain(LS), radial strain(RS), circumferential strain(CS)and area strain(AS) of the seven myocardial segments(BA,BAS,MA,MAS,AA,AS,A ),which accepted blood from the left anterior descending coronary artery. We analyzed the changes of the parameters before and after the coronary stent implantation. Results The 5/7 segment of the longitudinal strain(BA,MA,BAS,MAS,AA), 3/7 segment of area strain(BA,MA,MAS), 3/7 segment of circumferential strain (BA,BAS,MA)and 2/7 segment of radial strain (BAS,MAS)at 3~5 days after PCI were higher than that before the operation. The difference was statistically significant (P＜ 0.05). The longitudinal, circumferential, radial and area strain of the left anterior descending branch at 3 months after the operation were higher than that before and 3~5 days after the operation. The difference was statistically significant (P＜ 0.05). Conclusion 3D-STI may early evaluate the improvement of left ventricular regional systolic function before and after coronary artery PCI treatment in patients with coronary heart disease, and provide a basis for early clinical evaluation of PCI effect and follow-up treatment.

Objective To investigate the clinical features, etiology and prognosis of children patients with unexplained liver dysfunction. Methods The clinical data of 205 inpatients with unexplained liver dysfunction from January 2016 to December 2017 were analyzed retrospectively. The clinical characteristics, etiology and prognosis were analyzed. Results Of 205 patients with unexplained abnormal liver function, 166 patients with liver dysfunction (80.97%) were clearly diagnosed and involved in a variety of diseases. Among them, 104 cases were infected liver damage caused by non-hepatophilic virus, 38 cases were related to genetic metabolic diseases, 11 cases were drug-induced liver damage, 6 cases were Kawasaki disease, 4 cases were hematologic tumor diseases, 3 cases were malnutrition. The cause of abnormal liver function was not clear in 39 cases. Conclusion There are many and complicated causes of abnormal liver function, and part of the causes are unknown. Infantile liver dysfunction was mainly caused by non-hepatophilic virus, the first was cytomegalovirus, the second was Epstein-Barr virus; genetic metabolic disease, drug-induced liver damage, systemic disease are also an important cause of liver dysfunction.

目的 探讨自体心包膜组织对急性心肌梗死大鼠心脏功能的影响。方法 筛选合格的模型动物随机分为三组:心包去除组:仅去除心包膜;心梗组:前降支结扎法建立大鼠心肌梗死模型3周后仅开胸;移植组:前降支结扎法建立大鼠心肌梗死模型,3周后将心包膜移植于心肌梗死及周边区。实验4周后,通过心动图评价实验动物心脏功能,使用Masson染色检测动物心肌梗死大小,通过免疫荧光评价动物心肌存活率、观察血管新生状况,Western blot检测Caspase-3蛋白/Bcl-2基因表达情况。结果 4周后,心包去除组大鼠的心电图监测结果未见有室性颤动;而心梗组、心梗+移植组均有非致死性室性颤动。相比心梗组,心梗+移植组改善了心功能,降低了心肌凋亡指数,免疫Bcl-2蛋白表达升高,而Caspase-3蛋白表达降低。结论 提示自体心包膜移植不会导致恶性室性心律失常,相对有较高的安全性;并能促进心肌梗死细胞恢复心功能,其改善机制可能与通过修补心室重构途径同时抑制缺血区域细胞凋亡有关。

Objective To explore the effect of autologous pericardial transplantation for treating the myocardial infarction (MI) in experimental rats. Methods 30 SD rats were randomly divided in to three equal parts: Pericardial removal group (PR group): only pericardium tissue was removed; Myocardial infarction group (MI group): the anterior descending branch ligation method established a rat model of myocardial infarction and only opened the chest after 3 weeks. Autologous pericardium transplantation (APT group): After established the MI model of SD rats, 3 weeks later, the autologous pericardial patch was harvested and transplanted to infarcted zone. Four weeks after the surgery, the cardiac function and serum biochemistry were analyzed for all the experimental rats. The cardiac function was evaluated by echocardiography, which the size of the infarction were examined by Masson staining, the survival time of transplanted autologous pericardial and angiogenesis were measured by immunohistochemistry, the protein expressions of Caspase and the gene expressions of Bcl were examined by Western blot analysis. Results 4 week after the 2^nd operation, no ventricular fibrillation was detected in the ECG of PR group. Fatal ventricular fibrillation wasn't detected in the ECG of MI group and APT group. Compared with MI group, APT group improved cardiac function and decreased myocardial apoptosis index(P<0.05),which similar to PR group. APT group has the higher density of angiogenesis at infracted area to MI group but less than that of PR group. PT group had decreased protein expressions of Caspase-3 and the expressions of Bcl-2 were decreased. Conclusion Autologous pericardial transplantation could recover myocardial infarction cells, which will improve the cardiac function in experimental rats with MI.
