Objective To explore the changes and clinical value of serum insulin like growth factor-1 (IGF-1) and adiponectin in newborns with hypoxic ischemic encephalopathy (HIE). Methods Fifty-two HIE newborns were recruited in this study, including 15 severe, 20 moderate and 17 mild HIE newborns. Twenty healthy newborns were selected as controls. Serum levels of IGF-1 and adiponectin were detected 3-to-5 days (acute period) and 10-to-14 days (recovery period) after birth. Results Serum levels of IGF-1 and adiponectin in the acute period differed signiifcantly among groups of different severity (P<0.05). Serum levels of IGF-1 and adiponectin were decreased with the increase of HIE severity. The level of adiponectin in moderate and severe HIE was lower than that in mild HIE (P<0.05). In recovery period, the level of IGF-1 in severe HIE was lower than that in control (P<0.05). Serum levels of IGF-1 and adiponectin in the acute period was positivity correlated with those in umbilical cord blood of HIE newborns (r=0.531, r=0.611, P<0.01). Conclusions Decreased levels of IGF-l and adiponectin in HIE newborns are correlated with the pathological process of HIE, and can be regarded as indices for severity of HIE. IGF-l and adiponectin is of signiifcance in the clinical diagnosis and prognosis of HIE.

Objective To investigate the clinical significance of silent mating-type information regulation 2 homologue 1 (SIRT1) in hepatocellular carcinoma (HCC).Method We analyzed p53 mutation by gene sequencing and activation of SIRT1 and AMP-actived protein kinase (AMPK) using western-blot in 252 patients with hepatitis B virus-positive HCC.Results A higher proportion of tissues with mutant p53 were demonstrated to harbor activated SIRT1 (64.8％ vs 31.8％ ; P ＜ 0.01).Activated SIRT1 predicted a longer relapse-free survival.On multivariate analysis,activated SIRT1 remained significant (OR:0.339,CI:0.160-0.720,P =0.005).Analysis of 252 paired specimens revealed a significant correlation between activated SIRT1 and activated AMPK in HCC tissues harboring mutant p53 (P =0.007).Conclusion SIRT1 exerted anti-carcinogenic effects through the AMPK pathway in HCC in the context of mutant p53.

Objective To describe the early use of nasal continuous positive airway pressure (nCPAP) ventilation for infants presenting acute congestive heart failure (CHF) complicated by congenital heart disease (CHD) and pulmonary artery hypertension (PH).Methods Sixty infants with CHD treated for acute CHF were randomly divided into the nCPAP group (n =32) and the non-nCPAP group (n =28).Data were analyzed,which included lactic acid value (Lac) by arterial blood gas analysis,calculation of oxygenation index [pa (O2)/FiO2],detection of serum N-terminal pro-brain natriuretic peptide of type B (NT-proBNP) level,determination of left ventricular end diastolic volume index (LVEDVI),left ventricular ejection fraction (LVEF) and pulmonary artery systolic pressure (PASP) by noninvasive bedside ultrasonic cardiogram (UCG).Results 1.Comparison of arterial blood gas between the 2 groups:1 d after treatment,there were significant differences in pa (O2)/FiO2 and Lac between the 2 groups (t =4.743,5.402,all P ＜ 0.05).A significant difference was found in the pa (O2)/FiO2 between the nCPAP group and the non-nCPAP group 3-7 d after treatment(t =6.366,P ＜ 0.05).The level of Lac had no significant difference between the 2 groups 3-7 d after treatment(t =1.812,P ＞ 0.05).2.Comparison of index of heart function between the 2 groups:after 3-7 d treatment,LVEDVI,LVEF,and PASP were statistically different between the 2 groups (t =2.052,2.704,2.019,all P ＜0.05).3.Comparison of serum indexes between the 2 groups:3-7 d after treatment,serum NT-proBNP level was improved dramatically compared with the non-nCPAP group(t =9.869,P ＜0.05).4.Comparison of clinical prognosis between the 2 groups:the differences in needing endobronchial intubation rate,mechanical ventilation time,time in PICU and mortality rate were all statistically significant between the 2 groups (x2 =5.505,P =0.019; t =4.788,P =0.000;t =5.068,P =0.000 ;x2 =4.284 ;P =0.038).Conclusions The early use of noninvasive nCPAP for eligible patients with acute CHF complicated by CHD and PH seems to improve their prognosis by improving pa (O2)/FiO2,reducing left ventricular and right ventricular afterload and improving the left ventricular function.

Objective To evaluate the efficacy of less invasive stabilization systems (LISS) fixation and double plating on the treatment of AO-type C3 distal femoral fractures via anterior midline approach.Methods From June 2014 to March 2017,18 cases of AO-type C3 distal femoral fractures treated in our department were recruited in this study.They were 12 males and 6 females,at a mean age of 19-62 years.There were 11 cases due to traffic accidents and 7 due to falls from heights.Six of them had open fractures and 12 had closed fractures.They all were treated with LISS fixation and double plating with anterior midline incision.Kolment and Wulff criteria were used to evaluate knee joint function after internal fixation at the last time of follow-up.Results For all the subjects,the average operative time was 145 (110 to 200) min,and they were followed up for 17.5 (12 to 25) months.They all achieved primary wound healing,and had an average time of 22 (20 to 26) weeks for fracture healing.No nonunion,infection,osteomyelitis or injuries of nerves and arteries were observed.According to the results of Kolment and Wulff criteria for knee joint function evaluation,6 of them got excellent,9 good,2 fair and 1 poor outcomes,with a rate of 83.33％ for good and excellent outcomes.Conclusion The treatment of type C3 distal femoral fractures via anterior middle approach of knee joint can fully reveal the articular surface of the femoral condyle.And the operative vision is clear,making it easy for anatomical reduction of articular surface fractures.Combined with LISS double locking plates fixation treatment,it can avoid the injury of soft tissue,and the fracture also be rigid fixation.Postoperative early functional exercise should be allowed to obtain good clinical results.

Objective To study serum albumin levels in children with severe sepsis and to correlate serum albumin levels with patient outcome and to identify the causes inducing hypoalbuminemia and its effective countermeasures.Methods Seventy-five children admitted to PICU of Provincial Hospital Affiliated to Shandong University for severe sepsis were included in the study from Aug 2010 to Sep 2011.According to their serum albumin levels within 24 hours and on the third and the seventh day of admission to PICU,75 children were divided into hypoalbuminemia group and normal serum albumin group.Then hypoalbuminemia group was divided into instant hypoalbuminemia group and continuous hypoalbuminemia group according to the duration of hypoalbuminemia.The correlation between the occurring and duration of hypoalbuminemia with patients' prognosis,the etiopathogenisis of hypoalbuminemia and its effective countermeasures were analyzed.Results (1) Sixty-three cases (84.0％) proceeded hypoalbuminemia and their mortality was 33.3％ (21/63),while 12 cases (16.0％) showed normal serum albumin level and their mortality was 0.(2) In 63 patients with hypoalbuminemia,26 cases showed continuous hypoalbuminemia and their mortality was 46.0％,while 37 cases proceeded instant hypoalbuminemia and their mortality was 15.4％.There was significant difference (x2 =5.116,P ＜ 0.05) between their mortality.(3) In the 63 cases with hypoalbuminemia,32 cases presented with hepatic injury and their mortality was 37.5％,13 cases proceeded capillary leakage and their mortality was 23.1％,and 18 cases displayed hepatic injury complicated with capillary leakage and their mortality was 33.3％.There was significant difference (x2 =7.812,P ＜ 0.05) between the mortality with different causes.Conclusion Hypoalbuminemia influenced the prognosis of children with severe sepsis,the longer duration correlated with the worse prognosis.Hepatic injury and capillary leakage were two main causes inducing hypoalbuminemia.Active treatment of hypoproteinemia aimed directly at different causes could improve their prognosis significantly.

Objective To analyze the dose-effect relationship between cobalt protoporphyrin (CoPP) and heme oxygenase-1 (HO-1) expression in islets and to investigate the protective effect of strongly expression of HO-1 in islet xenotransplantation. Methods Donor islets isolated and purified from SD rats were randomly divided into 5 groups and incubated with different doses of CoPP for 24 h.Group A: 0 mmol/L; Group B: 5 mmol/L; Group C: 25 mmol/L; Group D: 50 mmol/L; Group E:75 mmol/L. The expression of HO-1 mRNA and protein in islets was detected by RT-PCR and Western blot respectively. Glucose of low and high concentrations was added to islets in vitro to test insulin-releasing function. The optimal dose of CoPP which could induce the strongest HO-1 expression was chosen according to the results. Recipients were randomly divided into 2 groups. Control group received untreated xeno-islets, and the experimental group received islets incubated with optimal CoPP close in vitro. Glycemia and rejection were observed after transplantation daily. Results The expression of HO-1 mRNA and protein in xeno-islets of group D was significantly higher than in other groups (P＜0.05). After stimulation of glucose, the insulin concentration in group D was significantly higher than in other groups (P＜0.05). The optimal dose of CoPP which could induce the strongest HO-1 expression was 50 mmol/L. The time for normoglyeemia in experimental group was (14.63±1.19) days, significantly longer than that in control group (9.88±2.17)days (P＜0.01). Conclusion The strongest expression of HO-1 induced by CoPP in vitro promotes the glucose-stimulated insulin secretion of islets and prolonged the survival of xeno-islet grafts by protecting them from rejection.

Objective To investigate the effects of peritoneal injection of cobaltic protoporphyrin Ⅸ chloride(CoPP)to induce heme oxygenase-1(Ho-1)upregulation in rat islet cells.Mthods Forty rats were divided into 5 groups by management 24 h before islets isolation:group A received inlzaporitoneal injection with 2.5 ms/ks CoPP,group B with 5 ms/ks CoPP,group C with 7.5 ms/kg CoPP,and group D with 10 mg/kg CoPP.In control group NS was used instead.A modified Goth approach was used for islet isolation.the yield and purity of the islets were assessed.The expression of Ho-1 mRNA and protein were detected by real time-PCR and Western blotting respectively.Islet function was tested by glucose stimulation test.Result Severe damage was found in tlle rats in group C and D.There was no difference in islet yield and purity for group A、B、C and control(P＞0.05).Group B had the highest Ho-1 mRNA and protein expression among the 4 groups.Though there was no difference in insulin secretion by low glucose challenge for group A、B and control's islets(P＞0.05),when challenged by hish level of glucose,significant deviation was observed.The imulin secretion level was(172.37±16.4)、(187.68±19.93)and(91.25±Conclusion Peritoneal iajection of 5 mg/kg CoPP can significantly enhance the expression of Ho-1 mRNA and protein in tat islet safely and enhance the function of islet when challenged by hish concentration of glucose.

Objective To assess the indication and safety of surgical resection of the pregnancy by hysterotomy (SRPH) and hysterectomy for cesarean scar pregnancy (CSP). Methods A retrospective study of women with CSP was conducted at the Women′s Hospital, School of Medicine, Zhejiang University, from Jan. 2003 to Mar. 2016. The women underwent SRPH (SRPH group, n=35) and hysterectomy (Hysterectomy group, n=14) were included. The gestational age (GA), size of gestational mass(GM), level of serum β-hCG, previous treatments and clinical outcomes were analyzed. Results The median GA, the mean size of GM, median serum β-hCG level, median amount of blood loss, rate ot blood transfusion, rate of persistent CSP, and rate of motal status in SRPH group versus Hysterectomy group were 66 versus 84 days, (65 ± 22) versus (92±36) mm, 23755 versus 802 U/L, 400 versus 650 ml, 11%(4/35) versus 13/14, 49%(17/35) versus 12/14, 20% (7/35) versus 14/14, respectively (all P<0.05). In SRPH group, median amount of blood loss was 500 ml in patients with GA≥10 weeks versus 300 ml in patients with GA<10 weeks (P<0.05). Serious complication occurred in 7 patients: severe pelvic inflammation in 1 patient and hematomas in the uterine isthmus in 1 patient in SRPH group; severe pelvic inflammation in 2 patients and hemorrhagic shock and DIC in 3 patients in Hysterectomy group. No blaader damage occurred. Conclusions SRPH is effective and safe for patients with CSP with GA of 9-10 weeks, a diameter of 60-90 mm and stable hemodynamics. Hysterectomy is an alternative to SRPH for patiens in motal status with advanced GA more than 12 weeks.
