Acute kidney injury ( AKI) in newborns is one of neonatal critical disease,the incidence of AKI is 23%and the mortality is 25%~50%in neonatal intensive care unit (NICU).AKI in newborns is ab-normal renal function due to many various unfavorable factors,such as neonatal asphyxia,low blood volume, shock,hypoxia,hemolysis,low temperature,the clinical manifestations are oliguria or anuria,electrolyte disturb-ance,acid-base imbalance, high concentrations of metabolites in plasma and renal excretion ( urea, creatinine etc.) .At present,there are no effective prevention measures.In recent years,with the progress of blood purifica-tion technology,continuous blood purification ( CBP) has been used from AKI in children to AKI in newborns. Because of the neonatal hemodynamic instability and blood characteristics of small capacity, the application of CBP in the neonatal AKI still faces many problems.The paper summarizes high risk factors and diagnostic crite-ria of AKI in newborns,related problems of neonatal CBP treatment.

Objective To explore the efficacy and safety of bedside continuous blood purification (CBP) in the treatment of neonatal multiple organ failure (MOF).Methods Totally 6 newborn infants of MOF were hospitalized in department of neonatology in our hospital from June 2011 to June 2013.These 6 cases of clinical data were retrospectively analyzed,6 neonates were treated with CBP combined with conventional treatment.The model for CBP was continuous veno-venous hemodialysis filtration (CVVHDF),blood flow velocity was 3 to 5 ml/(kg· min),replacement fluid dose was 20 to 30 ml/(kg· h),dialysis fluid dose was 15 to 25 rnl/(min· m2).The clinical outcome measures included,blood pressure,blood pH,K+,Na+,blood urea nitrogen,creatinine,urine volume,PaO2/FiO2 and epinephrine intravenous dose,respectively before CBP treatment,6 h,12 h,24 h,48 h after CBP treatment and the end of CBP treatment.The efficacy of CBP treatment was evaluated in neonatal MOF.Results Gestational age of 6 neonates with MOF was 33 to 41 weeks,2 to 19 days old,2.25 to 3.36 kg birth weight.Primary disease was 4 cases of neonatal septicemia(1 case with congenital hereditary metabolic disease),2 cases of severe neonatal asphyxia.All 6 cases of venous catheter were smoothly done.CBP treatment persisted for 49 to 106 hours.Compared with before CVVHDF treatment,blood K+,blood urea nitrogen,creatinine significantly decreased at 12 h after CVVHDF treatment [(5.32 ± 1.84) mmol/L vs.(9.81 ±3.61) mmol/L,(9.0 ±3.4) mmol/L vs.(12.8 ±6.1) mmol/L,(99 ± 16) μmol/L vs.(176 ±25) μmol/L,P ＜0.05],and reached the normal range at 24 h after treatment,urine volume significantly increased at 24 h after treatment (P ＜ 0.05).PaO2/FiO2 reached 200 mmHg (1 mmHg =0.133 kPa) at 6 h after treatment and more than 300 mmHg at 24 h after treatment(P ＜0.05).Fifty percent of epinephrine intravenous dose were down-regulation at 12 h after treatment and stopped using epinephrine at 48 h after treatment.CBP treatment of 6 cases showed effective.Conclusion Application of bedside CBP treatment in neonatal MOF is safe,can effectively help neonates with MOF to skip over renal failure stage.

Objective To explore the status of lymph node dissection under thoracoscopic surgery and open surgery in patients with thoracic esophageal carcinoma. Methods 16 cases of thoracic esophageal cancer received thoracoscopic surgery from August 2012 to June 2015 as minimally invasive group (group M), 17 cases of thoracic esophageal cancer with the same pathological staging received traditional open surgery during the same period as control group (group C), the number of lymph nodes and the positive rate of lymph node metastasis were compared. Results In group M, the total number of 228 lymph nodes, mean (14.27 ± 5.61) pieces, the positive rate was 12.50%; while in group C, the total number of 241 lymph nodes, mean (16.20 ± 6.24) pieces, the positive rate was 11.76%. Two different pathological staging in patients with lymph nodes dissection has no significant difference ( >0.05). In group M, 7 cases with lymph node metastasis, 45 metastatic lymph nodes, metastasis rate was 43.75 %, 19.74 % degree of metastasis; while in group C, 8 cases with lymph node metastasis, 55 metastatic lymph nodes, metastasis rate was 47.06%, transfer degree was 22.82%.Conclusions Minimally invasive surgery can achieve the same effect with the traditional open chest surgery, in treatment of thoracic esophageal cancer with high operability.

OBJECTIVETo evaluate the clinical efficacy and safety of phosphodiesterase 5 (PDE-5) inhibitors for erectile dysfunction (ED) in patients with diabetes mellitus and provide some evidence for the clinical treatment of the disease.

METHODSWe searched MedMed, EMbase, Cochrane Library, CNKI, Wan Fang Data, VIP and ZADL for randomized controlled trials on PDE-5 inhibitors for ED in diabetic men and evaluated the methodology of the included trials with the Jadad scale. We used the erectile function domain in the IIEF (IIEF-EF), IIEF questions (IIEF-Q) 3 and 4, SEP-2 and -3, and Global Assessment Questions (GAQ) as the main evaluation indexes and employed the Review Manager 5. 1. 0 software for meta analysis.

RESULTSA total of 13 studies were included, which were all high quality trials with Jadad score > 3. The IIEF-EF scores in 10 of the included studies were subjected to meta analysis using the random-effect model (REM), with a weighted mean difference (WMD) of 5.64 (95% CI 4.41 - 6.83, P < 0.001). The fixed-effect model (FEM) analysis of the IIEF-Q scores in 6 of the studies showed the WMD to be 0.96 (95% CI 0.83 -1.08, P < 0.001) for IIEF-Q3 and 1.11 (95% CI 0.98 - 1.25, P < 0.001) for IIEF-Q4. FEM analysis of the SEP-2 scores showed WMD = 17.67 (95% CI 12. 38 - 22. 97, P < 0.001) in 2 of the studies, and that of the SEP-3 scores WMD = 23.64 (95% CI 17. 49 - 29.79, P < 0.001) in 5 of the studies. The GAQ scores in 11 of the studies were subjected to REM analysis, with OR = 6. 20 and 95% CI 3.65 - 10.52 (P < 0.001). REM analysis was performed on the adverse reactions in 11 of the studies, with OR = 7.43 and 95% CI 4.11 - 13.44 (P < 0.001).

CONCLUSIONPDE-5 inhibitors can effectively and safely improve erectile function in patients with diabetes mellitus.

Objective To explore the clinical features, diagnosis, and treatment of non-immunologic hydrops fetalis (NIHF). Methods The clinical data of 10 cases of NIHF in neonatal intensive case unit during January 2011 to December 2016 were analyzed retrospectively. The related literatures were reviewed. Results In 10 cases of NIHF (6 males and 4 females). the gestational age were 32-42 weeks, and the birth weight was 2.25-3.95 kg. Among them, there were 3 cases of infectious diseases (cytomegalovirus, Streptococcus agalactiae, and parvovirus infection, one case each), 2 cases of fetal cardiovascular abnormalities, 2 cases of chromosomal abnormalities, 1 case of abnormal thoracic structures, 1 case of twin transfusion syndrome, and 1 case of etiology unknown of fetal hydrops. The clinical manifestations showed that there were 8 cases with 2 or more areas of edema (or hydrops), and only 2 cases with skin edema. Finally, 6 cases were cured and discharged, 2 cases were discharged by themself, and 2 cases died. Conclusions Prenatal ultrasound is a reliable method for the diagnosis of NIHF. Fetal edema in early pregnancy, especially with congenital malformations, is recommended for termination of pregnancy. After birth, NIHF should be diagnosed promptly so as to avoid or reduce severe complications.

OBJECTIVE:To improve the system of management and maintenance for the purification air-conditioning system in PIVAS,and to further strengthen the management of cleaning environment. METHODS:The cleanness monitoring project of purifi-cation air-conditioning system in PIVAS of our hospital was introduced in terms of temperature and humidity record,pressure differ-ence record,airborne particles detection,settling microbe monitoring report. And the monitoring results were analyzed. RESULTS:The temperature and humidity,pressure difference of clean area in PIVAS of our hospital are both in line with the standard of Phar-macy Intravenous Admixture Quality Management Specification (2010 edition),i.e. temperature at 18-26 ℃,relative humidity of 40%-65%;negative pressure difference between antibiotics,hazardous drug dispensing area and second dressing room are 5-10 Pa. The number of airborne particles (average static particle/m3) at various cleanness degrees in clean area are all in line with the standard of GMP(2010 edition),i.e. maximal allowable number of airborne particles(≥0.5 μm)were 3 520/m3(100 degree);352 000/m3 (10 000 degree);3 520 000/m3 (100 000 degree). The percentage of qualified static settling microbe detection reach 100%in clean area,which is in line with the standard of Settling Microbe Detection Method in Clean Room(Area) of Pharmaceu-tical Industry,i.e. criteria for settling microbe(90 mm)CFU/0.5 h≤1(100 degree);≤3(10 000 degree);≤10(100 000 degree). The percentage of qualified dynamic settling microbe detection is in low level,especially those of dispensing room and secondary dressing room only reaches 80%. CONCLUSIONS:It’s important for effective hospital infection control in PIVAS,the quality im-provement of intravenous injection,the safety guarantee of drug use in patients to further improve standard operation procedure of purification air-conditioning system management and maintenance,and manage and maintain the purification air-conditioning sys-tem completely and scientifically.

Objective To explore the efficacy and safety of bedside continuous blood purification (CBP) in the treatment of critically ill neonates.Methods Totally ten critically ill neonates were hospitalized in Department of Neonatal Intensive Care Unit (NICU) in Shanghai Children's Hospital from June 2011 to May 2015, and managed with CBP treatment.The indications of CBP therapy were multiple organ dysfunction syndrome (MODS) failed to conventional treatment or combined with acute renal failure (ARF).The model for CBP was continuous veno-venous hemofiltration dialysis (CVVH).The clinical outcomes included blood electrolytes, serum bio markers, urine output, hemodynamic indicators, dose of intravenous epinephrine before treatment, 6, 12, 24, 48 h after treatment and at the end of CBP.Complications of CBP were also observed.Statistical analysis was performed with ANOVA and Dunnett-t test.Results The underlying problems of the ten newborns were septicemia (n=5), severe neonatal asphyxia (n=2), congenital hereditary metabolic disease (n=2) and traumatic asphyxia (n=l).The venous catheter was successfully inserted for all babies and CBP treatment continued for (86.7 ± 25.9) h averagely with obvious effect.Four of the ten cases were cured and discharged, and the rest six refused to treatment and died after due to irreversible injury of the nervous system although they had survived from the oliguric stage of ARF.The complications of CBP included thrombocytopenia (n=3), catheter blockage (n=2), hypotension (n=l).No hypothermia, thrombosis, bleeding or infection occurred.The mean blood pressure and partial pressure of oxygen in arterial blood/fraction of inspiration oxygen (PaO2/ FiO2) of the ten cases 6 h after the beginning of treatment were higher than those before [(46.4 ± 7.5) vs (36.5 ±8.3) mmHg, 1 mmHg=0.133 kPa;(210.0±62.0) vs (93.0±43.0) mmHg;t=2.647 and 6.378, both P ＜ 0.05].At the 12th hour since treatment start, the blood pH value was 7.4 ± 0.2, which was higher than that before treatment (6.9 ± 0.2, t=2.731, P ＜ 0.05), and kept in normal range.At the 24th hour, the serum levels of potassium, urea nitrogen and creatinine dropped to normal range compared to those before treatment [(4.8±2.9) vs (9.6± 3.6) mmol/L;(7.2±2.3) vs (13.6±6.3) mmol/L;(51.0± 12.0) vs (172.0±23.0) μ mol/L;t=4.571, 5.427 and 21.672, all P ＜ 0.05].Urine output increased from zero before the treatment to (0.7±0.3) ml/(kg · h) after 24 h (t=3.284, P ＜ 0.05).The maintaining dose of intravenous epinephrine decreased since 12 h after the beginning of treatment and was ceased at the 48th hour.Conclusion CBP is an effective and feasible treatment for critically ill neonates.

Objective To explore the efficacy and safety of mild hypothermia (MH) in treating the infants with moderate-to-severe neonatal hypoxic-ischemic encephalopathy(HIE),and to make a follow-up of the nerve motor development of the infants at 18 months old after discharge.Methods Totally 61 neonates with moderate-to-severe HIE in Neonatal Intensive Care Unit (NICU) from Jan.2007 to Dec.2013 were retrospectively analyzed.According to before and after MH therapeutic apparatus was used by NICU of Shanghai Children's Hospital,61 neonates of HIE were divided into 2 groups,the conventional treatment group(25 cases) and MH treatment group(36 cases).The patients in both groups were measured respectively by using the amplitude integrated electroencephalography (aEEG) before MH treatment and at 72 hours after M H treatment,by neonatal behavioral neurological assessment(NBNA) on the 28th day after birth,and by adopting Bayley Scales of Infant Development at 18 months old.The adverse reactions,serious disability cases and deaths of MH treatment were recorded.Results Compared with the conventional treatment group,aEEG recording before treatment showed no statistically significant differences in MH treatment group [maximum voltage:(22.4 ±3.1) μV vs(18.6 ±2.5) μV,maximum voltage:(8.2 ±2.6)μV vs(6.5 ±1.9) μV,t =1.264,0.852,all P ＞ 0.05].However,aEEG recording at 72 h after treatment showed statistically significant differences in MH treatment group [maximum voltage:(24.1 ± 3.2) μV vs (30.6 ± 2.8) μV,maximum voltage:(9.7 ± 3.4) μV vs (13.3 ± 2.2) μV,t =6.376,4.257,all P ＜ 0.05].Severe disability cases [24.0％ (6/25 cases) vs 5.6％ (2/36 cases),x2 =4.405,P ＜ 0.05] and deaths [16.0％ (4/25 cases) vs 0 (0/36 case),x2 =6.1 64,P ＜ 0.05] in MH treatment group were significantly decreased,and there was significantly difference in NBNA on the 28th day after birth[(35.9 ± 2.1) vs(39.1-± 1.6),t =3.361,P ＜ 0.05],and scales of neurobehavioral evaluation through follow-up of 18 months old [mental development index (MDI):(85.2 ± 10.7) vs (96.5-± 13.1),t =7.839,P ＜ 0.05].Very few neonates had apnea,coagulation dysfunction,arrhythmia and other adverse reactions in MH treatment course.Conclusions MH treating moderate-to-severe HIE is safe and effective.MH is effective in reducing death and major disabilities in neonates with moderate-to-severe HIE and without significant side effects.MH can obviously improve the development of nervous system disorders in 0-18 months infants,and can significantly improve these infants' Bayley developmental scale neurobehavioral scores.

Objective To explore the effect of macrolide antibiotics(erythromycin) on tumor necrosis factor(TNF)-α and interleukin(IL)-8 in hyperoxia-induced lung tissue of premature newborn rats,and to study the intervention effect of erythromycin on hyperoxia-induced lung injury.Methods One-day old preterm Sprague Dawley rats were randomly divided into four groups by random number table method:air + sodium chloride group,air + erythromycin group,hyperoxia + sodium chloride group,hyperoxia + erythromycin group.Hyperoxia groups were continuously exposed to oxygen (oxygen ＞ 0.85) and air group in room air.After 1,7,14 days of exposure,the preterm rats of four groups were sacrificed,whole lung of these rats were isolated,the lung histological changes were observed by hematoxylin-eosin staining,TNF-α and IL-8 in pulmonary tissue homogenate were detected by ELISA.Results The results showed that:(1) Compared with air + sodium chloride group,TNF-α and IL-8 expression in hyperoxia + sodium chloride group were significantly increased(P ＜ 0.05) after 1,7 days of exposure [1 d:TNF-α:(16.163 ± 0.574) ng/ml vs.(21.923 ±2.066) ng/ml,IL-8:(18.214 ±3.649) ng/ml vs.(23.546 ± 5.240) ng/ml ;7 d:TNF-α:(15.940 ±0.821) ng/ml vs.(19.688 ±0.764) ng/ml,IL-8:(18.541 ± 4.114) ng/ml vs.(24.255 ±4.692) ng/ml],in particular,TNF-α expression appeared to increase earlier,their expression became significantly weak in 14 days (P ＜ 0.05).(2) Compared with hyperoxia + sodium chloride group,TNF-α and IL-8 expression in hyperoxia +erythromycin group became significantly weak after 1,7,14 days of exposure(P ＜0.05) after the intervention of erythromycin [1 d:TNF-α:(21.923 ± 2.066) ng/ml vs.(18.903 ± 1.851) ng/ml,7 d:IL-8:(24.255 ±4.692) ng/ml vs.(23.508 ±3.543) ng/ml,14 d:TNF-α:(16.443 ±5.466) ng/ml vs.(14.453 ±0.963)ng/ml],but their expression became weaker in 14 days than that in 1,7 days.Conclusion The release of inflammatory mediators TNF-α and IL-8 induced by oxidation outbreak participates in the development of hyperoxia induced lung injury,erythromycin may regulate immune function,inhibits the levels of oxidant-mediated TNF-α and IL-8 induced by oxidation outbreak,and alleviate hyperoxia lung injury in premature rats.
