Objective To explore the changes of amplitude integrated electroencephalogram (aEEG) during brain development in premature.Methods One hundred and forty-eight premature (gestational age 28-36 weeks) were selected.According to their gestational ages,148 premature were divided into 28-30 weeks group(40 cases),with 21 male,19 female;＞30-33 weeks group (49 cases),with 25 male,24 female;＞33-36 weeks group (59 cases),33 male,26 female.At the same time,40 cases of gestational age 37-40 weeks full-term newborns were selected as control group,with 23 male,17 female.Olympic CFM 6000 cerebral function monitor(produced by the American Natus company) was used to detect the changes of their aEEG,and analysis of the changes of aEEG were conducted.The first monitor was performed 3 days after birth,then once a week,monitoring for 2 hours each time,till the premature were discharged from hospital.The average of the monitoring data was obtained as a result for the analysis,and data analysis was conducted by using SAS 9.0 statistical software.Results The sleep-wake cycle continuity voltage positive rate and cycle occurrence rate of the 28-30 weeks,＞ 30-33 weeks,＞ 33-36 weeks premature were significantly lower than those of the 37-40 weeks full-term newborns (all P ＜ 0.05).The 28-30 weeks,＞ 30-33 weeks,＞ 33-36 weeks premature spectrun lower bound voltage value of quiet sleep cycle and activity sleep cycle were significantly lower than those of the 37-40 weeks full-term newborns (all P ＜ 0.05).The 28-30 weeks,＞ 30-33 weeks,＞ 33-36 weeks premature spectrum width of quiet sleep cycle and activity sleep cycle were significantly wider than the 37-40 weeks full-term newborns (F =13.444,11.982,all P ＜ 0.05).The 28-30 weeks,＞ 30-33 weeks,＞ 33-36 weeks premature total duration of sleep cycle were significantly higher than the 37-40 weeks full-term newborns (F =12.451,P ＜ 0.05).Conclusions With the increase of gestational age,premature brain development becomes gradually mature,and aEEG can reflect the degree of premature brain development to some extent.

Objective:To investigate the clinical efficacy of different doses of atorvastatin in the treatment of chronic heart failure.Methods:A total of 100 patients with chronic heart failure who received treatment in the Third People's Hospital of Bengbu Medical College from June 2019 to June 2020 were included in this study. They were randomly divided into a control group (conventional treatment + atorvastatin calcium tablet 10 mg, n = 49) and an observation group (conventional treatment + atorvastatin calcium tablet 20 mg, n = 51). Before and after 12 weeks of treatment, serum levels of N-terminal pro-brain natriuretic peptide (NT-proBNP) and inflammatory cytokines such as high-sensitivity C-reactive protein (hs-CRP), interleukin-6 (IL-6), interleukin-10 (IL-10) as well as ventricular remodeling (echocardiographic index) were compared between the two groups. Results:After treatment, serum level of NT-proBNP was (506.56 ± 62.37) pg/mL and (660.85 ± 74.55) pg/mL, serum level of hs-CRP was (14.74 ± 2.69) mg/L and (23.31 ± 3.45) mg/L, serum level of IL-6 was (36.77 ± 4.78) ng/L and (43.12 ± 5.22) ng/L, serum level of IL-10 was (12.36 ± 2.63) ng /L and (15.39 ± 3.56) ng/L, left ventricular end diastolic diameter was (37.74 ± 6.83) mm and (42.36 ± 7.73) mm, left ventricular ejection fraction was (45.78 ± 3.31)% and (42.63 ± 2.56)%, and the ratio of early (E wave) to late (A wave) diastolic velocities (E/A) was (1.44 ± 0.06) and (1.21 ± 0.03), respectively in the observation and control groups. There were significant differences in serum levels of NT-proBNP, hs-CRP, IL-6 and IL-10 as well as LVEDD and LVEF between the observation and control groups ( t = 3.73, 3.07, 3.58, 3.68, 2.99, 3.12 and 2.98, all P < 0.05). Conclusion:Atorvastatin is beneficial to the prognosis of patients with chronic heart failure. The therapeutic efficacy of 20 mg atorvastatin per day is better than that of 10 mg atorvastatin per day.

Objective To study the effect of trachea intubation and mechanical ventilation on the prognosis and discharge rate of patients with successful cardiac-pulmonary resuscitation.Method The clinical data of 389 patients,who were admitted from January 2005 to February 2007,were retrospectively analyzed.The relation between trachea intubation time and discharge rate was studied.According to the time from cardiac arrest to finishing trachea intubation,patients were divided into group A (within 3 minutes,n=209) and group B (over 3 minutes,n=143);according to the time from reaching emergency medicine department to finishing trachea intubation,the rest patients were divided into group C (within 5 minutes,n=9) and group D (over 5 minutes, n=38) minutes.The discharge rate was calculated between groups.The software of SPSS 11.0 was used for statistical analysis.Results The successful rate was 9.75% (389/3988),and 59 patients were discharged, with discharge rate 1.48% (59/3988).The discharge rate of group A was 19.62% (41/209),and was significantly higher than that of group B 6.99 % (10/143) (P

Two fragments G1 and G2 of the glycoprotein G gene of bovine respiratory syncytial virus(BRSV) were selected for expression in Escherichia coli based on the analysis of glycoprotein G by DNA Star software.Then the two fragments of glycoprotein G were amplified by PCR with synthesized G gene of BRSV as the template.The amplified fragments G1 and G2 are 570bp and 308bp in length,respectively.The PCR products were cloned into pET30a vector and expressed in soluble form in E.coli after induction of cultured E.coli with IPTG.Both of the recombinant proteins G1 and G2 were purified by immobilized Ni ion affinity chromatography under native conditions.Then the purified proteins were analysed by Western blotting.The results showed that the purified recombinant protein G1 retained good antigenicity and specificity.But the purified recombinant protein G2 didn't possess biological activity.Antibodies against BRSV were detected in suspected bovine serum samples in China by using indirect ELISA and Western blotting with the purified recombinant protein G1.The purified recombinant protein G1 might be used as antigen for establishing serological methods for diagnosis of BRSV infection.And the purified recombinant protein G1 might also be used for preparing polyclonal and monoclonal antibodies for research on biological functions of glycoprotein G of BRSV.

Objective To investigate the role of signal transduction of toll-like receptors(TLRs)in immunological pathogenesis in children with acute idiopathic thrombocytopenic purpura(ITP).Methods Thirty children with actue ITP and 30 age-matched healthy children were studied.Real-time fluorescent quantitative PCR was used to evaluate the levels of TLR 1-10 and signal transducing molecules,and cytokines associated with TLRs,such as IL-1?,granulocyte-macrophage colony-stimulating factor(GM-CSF),macrophage colony-stimulating factor(M-CSF)and IFN-?/? mRNA.Expressions of co-stimulatory molecules such as CD40,CD80 and CD86 in mo-nocyte/macrophage(MC)was analyzed by flow cytometry.Results Compared with healthy control group,the mRNA levels of TLR3,7,8 and 9 in ITP group were significantly up-regulated(Pa0.05).Transcription le-vels of MyD88-dependent and-independent pathway molecules such as MD-2,MyD88,IRAK-4,TRAF6,TAK1,TRIF,TRAM,TBK-1 and IFN-? were significantly up-regulated in acute ITP(Pa0.05).Conclusion Aberrant activation of toll-like receptors signaling may be one of the initiating factors of immune dysfunction in children with acute ITP.

Retroperitoneal laparoscopic live donor nephrectomy offers an intrinsic advantage over conventional transperitoneal laparoscopic nephrectomy because of the potentially lower risk for early and late donor intraperitoneal complications. Herein we presented our experience performing retroperitoneal laparoscopic live donor nephrectomy in 105 donors. All donor nephrectomy was successful. There were no donor deaths and no conversion to open surgery. Mean operation time was 112 min (range, 70-200 min). Intraoperative blood loss was 10-150 mL with an average of 30 mL. Warm ischemia time was 1.3 to 6 min with an average of 3.1 min. Postoperative retroperitoneal hematoma occurred in only one case and there were no other surgical complications. Donors were discharged from the hospital 5 to 10 days postoperation. Average postoperative hospital stay was 6.4 days. One graft was removed due to acute rejection. Delayed graft function occurred in two recipients but renal function returned to normal within four weeks. The other recipients had normal renal function in two weeks except three recipients in four weeks. We believe that retroperitoneal laparoscopic live donor nephrectomy is safe, reliable, and less invasive.
