Blood transfusion therapy is one of the commonly used intervention in newborn infants.Red blood cell transfusion is the only treatment for most cases of neonatal anemia,but the indications of application and implementation strategy are not yet perfect,and the benefits,adverse outcomes and potential risk of transfusion remains to be evaluated.There are many uncertain problems in transfusion management.This paper mainly introduces the evidence-based recommendations of neonatal blood transfusion released by Italian Society of Transfusion Medicine and Immunohaematology and Italian Society of Neonatology Working Group for reference of domestic clinicians.

Objective:To analyze the aberrant methylation of p16 gene in sera from primary liver cancer patients and to evaluate the clinical significance. Methods:A methylation-specific PCR was performed for the detection of promoter hypermethylation of p16 gene in blood DNA from 64 cases of PLC patients,and to anamyze the relationship between the aberrant methylation of p16 gene and the clinical pathological data . Results:76.6%(49/64)of the sera from 64 cases of PLC patients showed hypermethylation for p16 promoter,whereas no methylated p16 gene promoter were found in sera from liver benign diseases patients and normal control. Methylated p16 gene promoter in sera did not strongly correlated with HBsAg, AFP,stage ,metastasis and differentiation in PLC. Conclusion:Detection of the aberrant methylation of p16 gene in blood DNA from PLC patients might offer an effective means for the earlier auxillary diagnosis of the malignancy.

Objective: To analyze the aberrant methylation of death-asscciated protein kinase (DAPK) gene in blood from non-small cell lung cancer (NSCLC) patients and to evaluate its clinical significance. Methods: A methylation-specific PCR was performed for the detection of promoter hypermethylation of DAPK gene in blood DNA from 65 cases of NSCLC patients,and the relation of the aberrant methylation of DAPK gene and the clinical pathological data was analyzed. Results: 30.8% (20/65) of the blood from 65 cases of NSCLC patients showed hypermethylation in DAPK promoter, whereas no methylated DAPK gene promoter was found in blood from normal control or patients with benign lung diseases. DAPK gene promoter methylation in blood did not strongly correlate with the pathological class, stage, metastasis and differentiation of NSCLC. Conclusion: Detection of the aberrant methylation of DAPK gene in blood DNA from NSCLC patients might offer an effective means for the earlier auxiliary diagnosis of the malignancy.

BACKGROUND:Many foreign studies confirm that recombinant human growth hormone (rhGH) is a safe and effective agent for treatment of idiopathic short stature (iSS), but there are no long-period and systematical researches reported in China.OBJECTIVE: To observe the promoting effect of rhGH on the growth of children with ISS.DESIGN: Case-control observation.SETTING: Department of Pediatrics, the Affiliated Hospital of Medical College of Qingdao University.PARTICIPANTS: Ninety-eight children with ISS who were treated in the Department of Pediatrics, the Affiliated Hospital of Medical College of Qingdao University during December 2004 to March 2006 were involved in this study.Informed consents were obtained from the guardians of these children with ISS. According to the etiological factors, the children were assigned into 2 groups: ISS group (n =30) and growth hormone deficiency (GHD) group (n =68).METHODS : The children in ISS group and GHD group received subcutaneous administration of home-made rhGH (Jinsai Pharmaceutical Co.,Ltd., Changchun at 0.15 IU/(kg ·d) and 0.1 IU/(kg ·d) respectively before sleeping within 6 months.The body height, body mass and bone age were measured before, 3 and 6 months after treatment. The local region of injection was observed and the growth rate was calculated. Bone age was calculated by graphic atlas method and body height was predicated by BP method.MAIN OUTCOME MEASURES: Body height, body mass, bone age and growth rate of children in two groups before, 3 and 6 months after treatment.RESULTS: All the 98 children wereinvolved in the result analysis, without deletion. ①Intragroup comparison: The body height, growth rate of children in two groups 3 and 6 months after treatment were significantly superior to those before treatment [ISS group: body height:(126.5±9.4), (129.1±8.6), (121.1 ±11.0) cm (P ＜ 0.01), growth rate: (7.3±2.9), (7.5±2.7),(3.5±2.1) cm/year (P＜ 0.01); GHD group: body height: (111.0±13.0),(114.0±13.0),(108.0±12.0) cm(P＜ 0.01),growth rate: (13.2±3.5), (13.5±3.6), (4.0±2.9) cm/year(P ＜ 0.01)]. Six months after treatment, body height was increased in 27 of 30 children in ISS groups, and in all the 68 children in GHD group. ② Intergroup comparison: The growth rate of children in GHD group was concurrently higher than that in ISS group 3 and 6 months after treatment. ③Adverse reaction and side effect: During the treatment, hypothyroidism was observed in 2 children within 1 to 3 months of treatment,but there was no influence on growth rate after oral administration of thyroxin tablets. Local red swelling of skin was observed in another patient, which stopped automatically after one week duration, but the injection continued.CONCLUSION: Home-made rhGH is a safe and effective reagent for treatment of ISS. It can obviously enhance the body height and growth rate of children. Whereas the inhomogeneity of treatment effect does exist, what's more, therapeutic effect in ISS children is inferior to that in GHD children.

Objective To investigate pulmonary infect flora distribution characteristics of stroke patients with tracheotomy in Intensive care unit (ICU) and analyze the risk factors.Methods A total of 792 cases of ICU stroke patients was selected,including 426 cases of tracheotomy patients,and 366 cases of non-tracheotomy patients.The incidence of lung infections was compared.Bacteriological examination was used for tracheotomy bacteriological studies for lung infected stroke patients with tracheotomy.Bacteria infection's characteristics was observed.The risk factors were analyzed.Results (1) The tracheotomy patient 's lung infection rate was 23.00％,higher than 9.56％ of the non-tracheotomy patients,the difference was statistically significant (X2 =19.125,P ＜0.05);(2) For lung infection-occurred patients with tracheotomy of ICU,gram-negative bacteria infection rate was 63.97％,significantly higher than 19.85％ of gram-positive bacteria and 16.18％ of fungi,the difference was statistically significant (x2 =18.255,17.042,P ＜ 0.01);(3) Lung infection rate of ICU stroke tracheotomy patients with unconscious,dysphagia,hospitalization time ＞ 14 d,blood glucose levels ≥≥7.8 mmol/L,and based diseases was significantly higher than that of patients with conscious,non-dysphagia,hospitalization time ≤＜14 d,blood sugar level ＜7.8 mmol/L,and no based diseases (P ＜ 0.05);(4) Consciousness,dysphagia,hospitalization,blood sugar levels,and the underlying disease were the independent risk factors of lung infection in ICU stroke tracheotomy patients (OR1 =11.528,OR2 =8.046,OR3 =15.174,OR4 =7.795,ORs =10.784,P ＜0.05).Conclusions Gram-negative bacteria is the main reason for pulmonary infections in ICU stroke tracheotomypatients patients with stroke.State of consciousness,invasive treatment,hospitalization,blood sugar levels,and the underlying disease are the independent risk factors.

As a widely accepted and convenient method,the Apgar score has been applied to assess the status of the newborn infants and the response to resuscitation since 1952.But the Apgar score has also been used inappropriately in infants to predict specific neurologic outcomes in many cases.The Apgar Score produced by American Academy of Pediatrics(AAP) in collaboration with American College of Obstetricians and Gynecologists(ACOG),updated policy statements of the Apgar score in October 2015.The Apgar score has limitations,and it is not appropriate to use it alone to establish the diagnosis of asphyxia;the method does not predict individual neonatal mortality or neurologic outcome.AAP/ACOG encourages the use of an expanded Apgar score reporting form that accounts for concurrent resuscitation interventions.

Objective To investigate the clinical value of the Classification of acute pancreatitis2012.Methods Medical records and clinical data of patients with acute pancreatitis (AP) who were admitted to First Affiliated Hospital of Guangxi Medical University between October 2009 and September 2012 were retrospectively reviewed and analyzed.Patients were divided into mild acute pancreatitis (MAP),moderately severe acute pancreatitis (MSAP),and severe acute pancreatitis (SAP) groups according to the Classification of acute pancreatitis-2012.The number of improved and cured patients,length of hospital stay,hospitalization costs,rate of ICU admission,length of ICU stay,incidence of SIRS,and length of SIRS continue,Ranson scores,APACHE Ⅱ scores,computed tomographic severity index (CTSI) scores among the 3 groups were compared.Results One hundred and sixty-six patients with AP (119 males and 47 females) were included,and 76 were MAP,65 MSAP and 25 SAP.The average interval between AP onset and hospital admission was (2.27 ± 1.46) d.The number of improved and cured patients,length of hospital stay,hospitalization costs,rate of ICU admission,length of ICU stay,incidence of SIRS,and length of SIRS continue,Ranson scores,APACHE Ⅱ scores,CTSI scores increased with the severity of AP.The corresponding values in SAP group were 21 cases (84.0％),(23.8 ± 13.6) d,(53900 ± 30260) Yuan,48.0％ (12/25) and (5.76 ± 13.8) d,96.0％ (24/25) and (5.00 ± 2.40) d,(3.76 ± 1.30) score,(8.52 ± 4.24) score,(5.44 ± 3.48) score.Seventy-nine patients developed local complications,among them 34 was acute peripancreatic fluid collection,45 was acute necrosis collection.The incidence of acute necrosis collection in SAP group was significantly higher than that in MSAP group (68.0％ vs 44.6％,P =0.047),but the incidence of acute peripancreatic fluid collection in SAP group was significantly lower than that in MSAP group (16.0％ vs 46.2％,P =0.016).Organ failure occurred in 42 patients,among them 35 cases were respiratory failure,2 cases were renal failure,and 5 cases were respiratary and renal failure.The incidence of organ failure in SAP and MSAP group was 100％ and 26.2％,the difference between the two groups was statistically significant (P ＜ 0.05).Conclusions Classification of acute pancreatitis-2012 is a simple and convenient system,which can predict the severity of AP and appropriate for clinical application.

Neonatal hypoxic-ischemic encephalopathy as a standard term has been used for over 30 years,but now increasingly being questioned.Most experts recommend using neonatal encephalopathy instead of hypoxic-ischemic encephalopathy.The American College of Obstetricians and Gynecologists and The American Academy of Pediatrics published separately the report of Task Force on Neonatal Encephalopathy Neonatal Encephalopathy and Neurologic Outcome,Second Edition in 2014.Definition,diagnosis and treatment of neonatal encephalopathy and other content have been updated in the report.It is recommended that a comprehensive multidimensional assessment be performed of neonatal encephalopathy.This article will introduce the controversy about neonatal encephalopathy or hypoxic-ischemic encephalopathy and contents of the report of Task Force on Neonatal Encephalopathy.

To investigate me material basis of Mahuang Fuzi Xixin decoction (MFXD) for anti-inflammation and immune-suppression based on the combined method of serum chemical and serum pharmacological. The LC-MS/MS fingerprints of MFXD, drug-containing serum and blank serum were compared to define the components in plasma. Histamine, β-hexosaminidase released from RBL-2H3 cell infulenced by drug-containing serum at different time points were measured by ELISA. The effect of drug-containing serum on lipopolysaccharide-induced splenocyte proliferation at different time points were determined by MTT. A correlation analysis was made on components of MFXD and pharmacological indexes based the stepwise regression method. After the intragastrical administration with MFXD, 32 components were discovered in rat serum, including 27 prototype components (10 from Mahuang, 13 from Fuzi and four from Xixin) and five unknown components. Compared with blank serum, drug-containing serum could reduce the release of histamine from RBL-2H3 induced by antigen at different time points (P < 0.05); except the 4-hour drug-containing serum, all of the remaining drug-containing serums could inhibit the RBL-2H3 mastocyte degranulation induced by antigen at different time points (P < 0.05). Drug-containing serum could significantly lipopolysaccharide-induced mouse splenocyte proliferation at 15 and 30 min (P < 0.05). A regression analysis was made on the chemical data of components absorbed into blood and pharmacological indexes, i. e. release rate of histamine, release rate of β-hexosaminidase and inhibition rate of splenocyte. This suggested the close correlations among methyl pseudo-ephedrine, pseudoephedrine and histamine released from RBL-2H3 induced by antigen; pseudoephedrine, hypaconine, methyl pseudoephedrine and β-hexosaminidase released from RBL-2H3 induced by antigen; as well as benzoyl hypaconine, benzoylaconine, 14-benzoyl-10-OH-mesaconine, mesaconine and lipopolysaccharide-induced mouse splenocyte proliferation. Methylpseudoephedrine, pseudoephedrine, benzoyl hypaconine, benzoylaconine and mesaconine may be part of material basis of MFXD on anti-inflammation and immune suppression.
