OBJECTIVE: Post-traumatic healing style is an important link in the process of wound healing. Scarless healing of fetus skin after trauma is the ideal healing style that is hunted for by people. The results of studies on the mechanism of scarless healing were reviewed to explore the mechanism of scarless healing of fetus skin.DATA SOURCES: Computer was applied to retrieve Medline database on the articles relating to the mechanism of scarless healing of fetus skin from January 1970 to December 2003. Docuterms were "fetus, skin and scarless healing". Language in the articles was limited to English.STUDY SELECTION: The documents were examined at first to exclude the study on non-healing mechanism. Full texts were found in the surplus documents. The inclusive criterion was the foundational experiment on the mechanism of scarless healing. Clinical trial and phenomenal study on scarless healing were excluded.DATA EXTRACTION: Forty-eight articles on experimental study relating to embryonic scarless healing were collected in all. Sixteen experiments accorded with the inclusive criterion and 32 were excluded.DATA SYNTHESIS: Sixteen experiments discussed the relationship between the fetus and scarless healing on terms of growth environment, inflammation reaction to trauma and regulation of fibroblast in organism, extracellular matrix and nany cellular factors.CONCLUSION: Growth environment of fetus has not so much relationship with the mechanism of scarless healing after trauma. Low reaction of fetus to inflammation, different extracellular matrix, component of collagen fiber and cell factors may take part in scarless healing process. Regulation of gene expression may play an important role in the process. But the concrete mechanism of scarless healing is not clear yet and still needs more researches and elucidations.

Objective To explore the association of single nucleotide polymorphism-SNP44 of Calpain 10 gene with genetic susceptibility to type 2 diabetes in Kunming.Methods The polymorphism of site UCSNP44(T/C) in Calpain 10 gene was detected by Polymerase chain reaction and Allele specific amplification(PCR-ASA)in 131 type 2 diabetic patients and 131 non-diabetic controls who were selected using case-control study in the Kunming urban communities.Results The frequency of"C"allele and"TC"gene of SNP44 in type 2 diabetic patients was significantly higher than that in the controls.Conclusion The study suggested that the polymorphism-SNP44 of Calpain10 gene may be associated with genetic susceptibility to type 2 diabetes in Kunming population.

Objective To investigate the intervention effects of NLP workshop on resilience of children from divorced family.Methods A pre/post test and subsequent follow-up design between experimental group and control group were performed.Thirty-one children from divorced family with low resilience were intervened by NLP workshop,while the other thirty-one children with low resilience were chosen as the control group.Results There was no significant difference between experimental group and control group before the intervention on resilience.But after the intervention,the two groups achieved statistical significant difference on resilience(experimental group (3:68±0.37),control group(2.99±0.18),t=9.60,P=0.00).Furthermore,the results of follow-up showed that the effect of NLP workshop still existed after six months (total average score of resilience before intervention (2.96±0.17),subsequent follow-ups (3.69±0.35),t=10.40,P=0.00).Conclusion NLP workshop can enhance the level of resilience of children from divorced family.Effect of NLP workshop not only has short-term effect,but also has some long-term effect.

Acute myeloid leukemia (AML) is the most commom hematologic malignancy in adults.There are so many highlights in the 54th ASH annual meeting in the field of mechanism,diagnosis and treatment of AML.Especially many studies have identified genes close related to AML development,clones related to relapse and molecular marker for prognosis using next-generation sequencing (NGS).Minimal residual disease (MRD) assay has been used for evaluation of therapy efficacy and posttherapy prognostication in AML treatment.The tyrosine kinase inhibitor targeting FLT3-ITD in this meeting is the best highlight in the treatment of refractory and relapsed AML.

Acute myeloid leukemia (AML) is the major topic in American Society Hematology (ASH)Annual Meeting and Exposition. There were 887 scientific articles on AML in the 53rd ASH Annual Meeting and Exposition in 2011,in which many studies focused on clinics.Here is introduction of o.ptimized regimens for AML and elderly AML,as well as targeted therapy for AML presented in the meeting.

Objective To investigate the application value of the Mini-Nutritional Assessment (MNA) in assessing the nutritional status in middle-aged women with diabetes.Methods Using the normal range of traditional nutritional index as the reference standard,two hundred and forty middle-aged women with diabetes were recruited and their nutritional status were assessed by MNA and laboratory test (including PAB,Fib,TLC,CHOL),respectively.Finally,the results were analyzed and compared.Results The correlation coefficient of MNA value and BMI、PAB,Hb,TLC,CHOL were 0.571,0.614,0.781,0.568,0.218.MNA had good correlations with several traditional laboratory indicators regarding with nutritional status,with signifi-cant difference.In this study,the results of investigation by MNA showed that:the rates of malnutrition,potential malnutrition,and normal nutritional were 30％(72 cases),65％(156 cases),and 5％(12 cases),respectively.The sensitivity and specificity of MNA were 96.1％ and 98.2％ respectively.Laboratory testing resuits:malnutrition and normal nutrition were 31％ (74 cases) and 4％ (10 cases).Kappa test(Kappa=0.922):the results of MNA and laboratory testing had strong consistency.Conclusions MNA is feasible in assessing nutritional status in the domestic middle-aged women with diabetes.

Objective The purpose of this study was to evaluate the importance of the interhospital transport of critically ill pediatric patients by analyzing the epidemic characteristics of pediatric patients transported from 2009 to 2012.Methods Nine thousand two hundred and thirty-one referral patients from January 2009 to June 2012 were evaluated by a cross-section study.Epidemiological data such as sex,age,seasons,and referral radius were collected.Results Among all the interhospital transport of critically ill pediatric patients,male to female ratio was nearly 2.24 to 1 and 87.39％ (8067/9231) patients were neonates and infants.Of all patients,66.32％ (6122/9231) patients were from department of pediatrics,neonatology or gynaecology and obstetrics in referring hospitals.The distribution of referring department among years was statistically significant in referring patients (x2 =227.53,P ＜ 0.000 1).Among the patients,56.88％ (5251/9231) were transported over 150km radius and only 12.18％ (1124/9231) patients in 50 km.52.89％(4882/9231) were transported in spring and winter.The seasonal distribution of interhospital transport of critically ill pediatric patients was statistically significant(x2 =1201.88,P ＜0.000 1).The majority of referral telephones were received between 9 AM to 12 AM.Conclusion With the limitation of equipment and technical measure in primary hospitals,critically ill pediatric patients should be transported to tertiary hospitals.According to the epidemiological characteristics of interhospital transport of critically ill pediatric patients,some measures should be adopted for the timely,safe and effective interhospital transportation.

In this year,ASH annual meeting reported several new targeting therapeutic drugs for chronic lymphocytic leukemia (CLL) and a part of lymphoma.Those drugs focus on some key targets in the signal transductional pathway of B cells.Although these targeting drugs individually did not improve the complete remission rate of CLL,but several clinical trial results showed that the combination therapy of those drugs with other drugs significantly improved the efficacy of CLL,and prolonged the progression-free survival of CLL patients.Therefore,experts believe that combination therapy and sequential therapy will start a new era in the treatment of CLL.This paper will share only the latest advances in the treatment of CLL and parts of lymphoma with domestic readers.

Objective To investigate the effect of perioperative anesthesia management on postoperative complications of laparoscopic operation for elderly patients,and to provide reference for the clinical anesthesia man-agement.Methods 90 elderly patients who received laparoscopic surgery were randomly divided into observation group and control group,45 cases in each group.The control group was treated with the routine intervention of the perioperative anesthesia management,and the observation group was given to strengthen the perioperative anesthesia management.The intubation,skin incision,withdrawal of blood pressure,heart rate changes before surgery,and abnor-mal blood pressure,chills,hypoxemia,ischemic heart disease,incidence of complications after surgery were compared between the two groups.Results Before surgery,the withdrawal of the systolic blood pressure,diastolic blood pres-sure,heart rate between the two groups had no statistically significant differences (P >0.05 ).In the observation group,during tracheal intubation for systolic blood pressure (136.92 ±19.57 )mmHg,diastolic blood pressure (84.57 ±12.39)mmHg,after skin incision systolic blood pressure (126.93 ±16.68)mmHg,diastolic blood pressure (78.43 ±11.76)mmHg,which were significantly higher than those in the control group (P <0.05).In the observa-tion group,during tracheal intubation the heart rate was (74.46 ±11.28)/min,which was significantly lower than the control group (P <0.05),abnormal blood pressure of the patients in the observation group was 8 cases,2 cases of shivering,hypoxemia in 1 case,the incidence rate of postoperative complications was 24.44%,abnormal blood pres-sure after surgery in the control group had 15 cases,4 cases of shivering,hypoxemia in 5 cases,ischemic heart disease 2 cases,the incidence rate of postoperative complications was 57.78%.The incidence of postoperative complications in the observation group was significantly lower than that of the control group (χ2 =14.58,P <0.05).Conclusion To strengthen the perioperative anesthesia management helps to reduce the blood pressure and heart rate fluctuations during perioperative period,and can reduce the incidence of postoperative complications and improve the safety of anesthesia.
