Encephalopathy of prematurity is still an important reason which affects the survival and quality of life of preterm infants. During hospitalized in neonatal intensive care unit(NICU),a variety of environmental factors such as noise,light,too much tactile stimuli,pain,and maternal - infant separation all will affect the development of preterm infants' brain,leading to encephalopathy of prematurity. Therefore,need to attach importance to the effects of NICU environment on the growth and development and the neurological function of preterm infants,try to optimize the environment of NICU,to reduce the incidence of brain injury of prematurity,improve the long - term prognosis of pre-term infants.

Objective To observe the effectiveness and salty of Xiaoer Dingfeng Decoction(Decoction to stop wind in children con- vulsion)in the treatment of syndrome of primary infantile convulsion due to phlegm-heat in tonic-clonic epilepsy.Methods Totally 90 infantile patients were randomized into three groups,which were treated by Xiaoer Dingfeng Decoction,Kangxian(Capsule to treat epilepsy)and Xifeng Capsule(Capsule to calm the wind)respectively.Frequency of seizure,lasting duration,and change of electroen- cephalogram(EEG)were observed 12 months later.Results The total effective rate of Xiaoer Dingfeng Decoction group was 86. 67%,better that that of Kangxian Capsule group(P0.05). It could greatly reduce the frequency of seizure,shorten the lasting duration,and improve the EEG.Conclusion Xiaoer Dingfeng De- coctions is effective and safe for the syndrome of primary infantile convulsion due to phlegm-heat in tonic-clonic epilepsy.

Objective To study the expression of Toll-like receptor-2 (TLR-2) and caspase-3 in the intestine of premature rats with necrotizing enterocolitis (NEC),and to explore the protective effects and possible regulatory mechanism of glutamine (Gln) in the NEC.Methods Sixty premature rats (gestational age 21 d) were divided into three groups (n = 20 each) according to the random number table: control group,model group and Gln intervention group.Rats in model group were given formula feeding,hypoxia and cold stress.Rats in Gln intervention group were given Gln 0.3 g/kg to the formula feeding,hypoxia and cold stress.All the premature rats were sacrificed and the intestine tissues were obtained on the third day after birth.The histological changes of ileal tissues were scored after HE staining.The expression of TLR-2 and caspase-3 in jejunum,ileum and colon were detected by inmunohistochemistry,and the expression of TLR-2 mRNA in jejunum,ileum and colon were detected by real-time fluorescence quantitative reverse transcription-polymerase chain reaction.Results Pathology score of ileum in model group,Gln intervention group and control group were 3.10 ±0.99,2.40 ± 0.69 and 0.30 ±0.48,respectively.The expressions of TLR-2 protein in ileum were 2.53±0.94,2.15±0.82 and 1.57 ± 0.62 in the three groups respectively,and the expression of caspase-3 protein were 2.83 ± 0.45,2.70 ± 0.04 and 0.91 ± 0.29.The content of TLR2 mRNA in model group was 1.46 times higher than that of Gln intervention group and was 2.10 times higher than that of control group.Compared with the control group,the pathology score,expression of TLR-2 and caspase-3 protein,and TLR-2 mRNA in model group were significantly higher,P＜0.01.However,compared with the model group,those changes were improved in Gln intervention group,P＜0.05.Expression of TLR-2 mRNA positively correlated to the expression of caspase-3 protein (r=0.71,P＜0.01) and pathology score (r = 0.69,P＜ 0.01).Expression of caspase-3 protein positively correlated to the intestine injury pathology score (r=0.81,P＜0.01).Conclusions TLR-2 may be involved in the pathogenesis of NEC.Gln might reduce the expression of TLR-2 in the intestine,and decrease the apoptosis of intestinal epithelial cells to protect the intestine of preterm birth rats.

Objective To analyze the distribution and clinical characters of cyanotic congenital heart diseases in newborns.Method We examined the suspicious cases with color doppler ultrasonic cardiogram(CFM),and compared with the results of autopsies.Results The most common congenital diseases in the group were complete transposition of the great arteries,with the proportion of 34.4%, and most of them were compounded cardiovascular disorders. The most common symptom was cyanosis, took the proportion of 84.3%; some patients had no cyanosis, tachypnea and murmurs.The cases with cardiovascular disorders most were combined with type Ⅱrespiratory failure and metabolic acidosis.Conclusions There are many types of congenital heart diseases, the symptoms are untypical,so the suspicious cases shall examine with CFM as early as possible.

Objective To establish and evaluate three different necrotizing enterocolitis models,established by combination of formula feeding, hypoxia and cold exposure, hypoxia-reoxygenation, and intraperitoneal injection of lipopolysaccharides (LPS) in premature rats. Methods Group A was given formula feeding, hypoxia by exposing to 100% N2 for 90 s and 4 ℃ cold stress for 10 minutes, the hypoxia and cold stress were given twice a day for 2 d. Group B was put into 100% N2 for 5 min and then 100% O2for 5 min, twice a day for 3 d. Group C was injected intraperitoneally 5 mg/kg LPS. Group D, E and F were served as the corresponding controls for group A, B and C. Ileocecal junction, liver, kidney and lung tissues were harvested and evaluated by HE staining for histological analysis, histological changes of ileal tissues were scored, and rats with score higher than two were diagnosed with NEC. Results Premature rats in group A, B and C showed various degrees of decreasing activity, abdominal distention, diarrhea,intestinal dilatation and congestion. Histological score in group A to F were 3. 13 ± 0. 64, 1.40 ±0. 52,2. 00±0. 42,0. 30±0. 48, 0. 30±0. 48 and 0. 40±0. 52, respectively. There were significant differences between model groups and their corresponding control groups (P＜0. 01 ). Among the model groups, the histological score of group A was higher than group B (P＜0.01) and group C (P＜0.05). The incidences of NEC in group A, B and C were 6/8, 20% (5/10) and 4/8, respectively, while of zero in all control groups. Liver, kidney and lung injures were more serious in group C compared with the other groups.Conclusions Compared with the single-factor modeling approaches of intraperitoneal injection of LPS and hypoxiareoxygenation, the NEC animal model in preterm rats established by formula feeding, repeated hypoxia and cold exposure, is more similar to the etiological factors of neonatal NEC in human, with higher incidence, better reproducibility and specificity.

Objective To analyze the changes of electroencephalographic activities during fully automated simultaneous peripheral arteriovenous exchange transfusion(ET) in neonates with hyperbilirubinemia.Methods A total of 45 neonates who suffered from severe hyperbilirubinemia and underwent fully automated simultaneous peripheral arteriovenous exchange transfusion were studied from March 2009 to March 2016 in Neonatal Intensive Care Unit of Guangzhou Women and Children's Medical Center,and 46 ETs were performed in 45 babies who were divided into 2 groups according to the severity of hyperbilirubinemia:the encephalopathy group and the none-encephalopathy group.Nineteen patients were in the encephalopathy group,in which 11 were male and 8 were female.The other 26 patients were in the none-encephalopathy group,in which 15 were male and 11 were female.Changes in amplitude integrated electroencephalogram(aEEG) during ETs were analyzed,including background activities,sleep-wake cycle (SWC)and seizures.Results Forty-five patients with hyperbilirubinemia underwent 46 fully automated simultaneous peripheral arteriovenous ETs.As a result,total bilirubin dropped from (524.90 ± 110.96)μmol/L before ETs to (245.62 ±78.97) μmol/L after ETs,with clearance rate of 53.2％.And indirect bilirubin dropped from(486.16 ±90.39) μmol/L before ETs to(222.19 ± 79.49) μmoL/L after ETs,with clearance rate of 54.3％.On the other hand,there was no significant difference in the changes of electroencephalographic activities during ETs,including background activities (x2 =0.16,P ＞ 0.05),SWC (x2 =0.71,P ＞ 0.05) and seizures (x2 =0.30,P ＞ 0.05).However,there were significant difference in suppressions on background activities between the encephalopathy group and the none-encephalopathy group(Fisher's exact test P =0.042),though there were no significant statistical differences in SWC or seizures between the 2 groups (x2 =0.65,P ＞ 0.05;x2 =2.07,P ＞ 0.05,respectively).Conclusions In neonatal hyperbilirubinemia,fully automated simultaneous peripheral arteriovenous ET is safe and efficient without significant influence on electroencephalographic activities as a whole.However,background activities are more significantly depressed in infants of bilirubin encephalopathy than that of non-encephalopathy during ET.

Objective To investigate the clinical efficacy of electroacupuncture in treating mild and moderate female stress incontinence.Methods One hundred and eighty female patients with mild or moderate stress incontinence were randomly allocated to treatment and control groups, 90 cases each. The treatment group received electroacupuncture and the control group took midodrine hydrochloride tablets. The International Consultation on Incontinence Questionnaire Urinary Incontinence Short Form (ICIQ-UI SF) score was recorded and 1-hour pad test leakage was measured in the two groups before and after treatment. The clinical therapeutic effects were compared between the two groups.Results There were statistically significant pre-/post-treatment differences in the ICIQ-UI SF score and pad test leakage in both groups (P<0.01). There were statistically significant post-treatment differences in the ICIQ-UI SF score and pad test leakage between the treatment and control groups (P<0.01). The total efficacy rate was 86.7% in the treatment group and 68.9% in the control group; there was a statistically significant difference between the two groups (P<0.05).Conclusions Electroacupuncture is an effective way to treat mild and moderate female stress incontinence. It can improve urinary continence and reduce urine leakage in the patients.

ObjectiveTo investigate the effect of vitamin D supplementation on the outcome of acute ischemic stroke in young patients with vitamin D deficiency.MethodsThe prospective controlled study was used to select the consecutive young patients with acute ischemic stroke.Vitamin D deficiency was defined as 25-hydroxyvitamin D (25(OH)D) ≤50 nmol/L.The Patients with vitamin D deficiency were randomly divided into an intervention group and a routine treatment group according to the random number table method.Routine treatment group didn't receive the drug intervention for vitamin D deficiency, and the intervention group received daily oral alfacalcidol 0.5 μg.After 1 year of treatment, the 25(OH)D levels were examined again;the adverse reactions during the drug treatment were monitored;the modified Rankin Scale (mRS) was used to evaluate the functional outcome and 0-2 was defined as good outcome.ResultsThere are 94 patients (53.41%) with vitamin D deficiency among 176 young patients with acute ischemic stroke.They were randomly divided into either an intervention group or a routine treatment group (n=47 in each group).At the end of the follow-up, the good outcome rate (82.98% vs.63.83%;χ2=4.414, P=0.036) and serum 25(OH)D level (85.83±10.53 nmol/L vs.39.10±11.18 nmol/L;t=20.860, P<0.001) in the intervention group were significantly higher than those in the routine treatment group.During the follow-up period, there was no loss to follow-up or death events in both groups.Only 2 cases of nausea and 1 case of dizziness were observed, and the incidence of adverse reaction was 6.38% in the intervention group.ConclusionsVitamin D supplement can increase the vitamin D levels and improve functional outcome in young patients with acute ischemic stroke and vitamin D deficiency.
