The process of late lung development is disturbed in bronchopulmonary dysplasia (BPD).One of the keys in late lung development is secondary septation, in which secondary septa arise from primary septa, producing plenty of small alveoli, which significantly increase the surface area of gas exchange.Secondary septation,together with architectural changes to the vascular structure of the lung which minimize the distance between the blood and the inspired air, are the targets of late lung development.BPD is a disease of premature infants in which development of the alveoli is stunted caused by many factors including volutrauma,inflammation,and oxygen toxicity.Compared with early lung development, the later development of the immature lung remains unclear.This paper is to emphasize remarkable latest research of arrested late lung development and BPD.

Objective To review the quantitative relationship of polymorphism at the sites +49 of cytotoxic T-lymphocyte associated antigen 4 gene with the susceptibility of Graves' disease(GD) in Asian population.Methods The Medline,PubMed,Embase,Web of Science,and Chinese Biomedical Literature Database on disc (CBM disc) databases were searched and used in meta-analysis to analyze the data in the articles collected.Results This analysis included a total of 24 papers,and GD patients and healthy population control group were composed of 4 832 cases and 5 643 subjects respectively.This paper revealed that in the general population,the Chinese people and the Japanese crowd,all the genetic models (allele,co-dominant model,dominant model,recessive model) were statistically significant,indicating that CTLA-4 +49 A allele could reduce the risk of GD.Conclusions The CTLA-4 +49 G→A mutation allele may serve as a factor in reducing the risk of GD susceptibility in Asian population.

Objective To investigate the clinical value and effect of peripherally inserted central eatheter(PICC) in patients with tuberculous meningitis. Methods 56 patients with tuberculous meningi-tis were randomly divided into the treatment group and the control group with 28 cases in each group. The treatment group was medicated by PICC, while the patients of the control group were medicated through pe-ripheral superficial vein. The curing rate, degree of anxiety, infusion response, satisfaction with nursing and related expense were recorded. Results The curing rate and satisfaction with nursing of the treatment group were higher than those of the control group. The anxiety degree, infusion response and related ex-pense of the treatment group were lower than those of the control group.Their difference had statistical sig-nificance. Conclusions PICC has clinical value in patients with tuberculous meningitis,which is worth promoting.

To explore the change in gene expressions of p38 mitogen-activated protein kinase (p38MAPK) and its upstream signal-regulated molecule (mkk3 and mkk6) in normal skin versus hypertrophic scars underlying its potentially biological significance. Total RNAs were isolated from 8 specimens of hypertrophic scars and 8 specimens of normal skin, then they were purified to mRNAs, and the gene expression of mkk3, mkk6 and p38MAPK was examined with reverse transcription-polymerase chain reaction (RT-PCR). The results showed that the intensities of gene expression of mkk6 and p38MAPK were weak in normal skins, while the expression of these 2 genes was significantly elevated in hypertrophic scars compared with normal skins (P0.05). In hypertrophic scar, the elevation of mkk6 and p38MAPK gene expression, which plays pilot roles in cell proliferation, may be one of the mechanisms controlling the formation of hypertrophic scars.

To investigate the effect of FGF-10 on the secretion of GM-CSF by adult keratinocytes in vitro and to understand the mechanisms involved in the stimulation of granulation tissue formation by FGF-10 during wound healing. Concentrations of FGF-10 used were 4, 16, 125 and 500 ng/ml. Cells were seeded in the amount of 2 500 cells/cm 2 or 5 000 cells/cm 2 in dishes in serum-free medium, and supernatants were collected at 24, 48 and 72 hours after culture. The amounts of GM-CSF in cell culture supernatants were determined using GM-CSF ELISA kits, and cell numbers were counted by haemocytometer. For cells seeded in low density (2 500 cells/cm 2), GM-CSF was not detected at 24 hours. At 48 hours, both in absolute concentrations and on a per-cell basis, the amounts of GM-CSF secreted in cultures with 125 and 500ng/ml FGF-10 were significantly higher than that in negative control (P0.05). At 48 hours, the keratinocytes in the middle area were confluent, and a number of cornified cells were observed, while the productions of GM-CSF in FGF-10 cultures were not higher than that in negative control. There was a clear negative correlation between the secretion production of the growth factor and the total cell number in each dish with a correlated coeffecient of 0.881 (P

There are many problems existing in humanities and social science courses in education and teaching of medical colleges and universities.Changing concepts of education,adjusting the curriculum,improving teaching methods and improving the quality of teachers are effective measures in medical colleges to strengthen the humanities and social science courses.We have made a preliminary exploration on teaching practice for humanistic education and professional education.

Objective To evaluate the effect of flurbiprofen axetil pretreatment on the level of central β-endorphin in a rat model of incisional pain.Methods Fifty-four SPF male healthy Sprague-Dawley rats,aged 6-7 weeks,weighing 180-230 g,were divided into 3 groups (n=18 each) using a random number table:control group (group C),incisional pain group (group Ⅰ) and flurbiprofen axetil pretreatnent group (group FA).At 30 min before the model of incisional pain was established,fat emulsion 1 ml was injected via the caudal vein in group Ⅰ,and flurbiprofen axetil 6 mg/kg (diluted to 1 ml in fat emulsion) was injected via the caudal vein in group FA.The mechanical paw withdrawal threshold (MWT) was measured at 1 day before establishment of the model and 1,6 and 12 h after establishment of the model (T1-3).The rats were sacrificed after measurement of pain threshold at T1-3,and the lumbar enlargement segment of the spinal cord and hypothalamic arcuate nucleus specimens were obtained for determination of β-endorphin content (by enzyme-linked immunosorbent assay) and β-endorphin expression (by immunohistochemistry).Results Compared with group C,the MWT was significantly decreased at T1-3 in I and FA groups,the content and expression of β-endorphin in the spinal cord were significantly decreased at T2,3,and the content and expression of β-endorphin in the hypothalamic arcuate nucleus were increased at T1 in group Ⅰ,and the content and expression of β-endorphin in the spinal cord and hypothalamic arcuate nucleus were significantly increased at T1-3 in group FA (P＜0.05).Compared with group Ⅰ,the MWT was significantly increased,and the content and expression of β-endorphin in the spinal cord and hypothalamic arcuate nucleus were increased at T1-3 in group FA (P＜0.05).Conclusion The mechanism by which flurbiprofen axetil pretreatment produces analgesic effect may be related to the increased level of central β-endorphine in a rat modal of incisional pain.

Objective To evaluate the application effect of UK manual moving & handling skills in the training of preventing occupational lower back pain among nursing professionals,and explore effective ways of training on preventing occupational lower back pain to nursing professionals.Methods 86 nursing students,94 nurses with 12 months' work experience,and 88 nurses with work experience over 5 years were randomized selected,and they each were divided into the experimental group and the control group.For 86 nursing students,43 students in each group; For 94 nurses with 12 months' work experience,47 nurses in each group; For 88 nurses with work experience over 5 years,44 nurses in each group.A routine taught training was given to both groups,while the experimental group received an extra 25 academic hours' structured OLBP prevention training.Comprehensive proposition was used to assess theoretic learning outcome of all participants,and practical skills of all participants were tested through institutional cases.Ressults There was significant statistical difference between scores of participants from two groups,and the scores of the experimental group in nurses with 12 months' work experience were different from the experimental groups of nursing students and nurses with work experience over 5 years.Conclusions Structured OLBP prevention training should lead occupational health prevention and health promotion concepts,apply numerous teaching approaches,emphasize the content of maintaining physical and psychiatric health and occupational protection management,set new-enrolled nurses as the main focused group of training.

The medical records of all 12 patients diagnosed as chronic active Epstein-Barr virus (CAEBV) infection at our hospital were analyzed retrospectively.There were 7 males and 5 females with a median onset age of 28 years.CAEBV was characterized by fever,splenomegaly,hepatomegaly and lymphadenopathy,etc.The abnormalities of laboratory examination included liver dysfunction,thrombocytopenia,anemia and leucopenia.EBV-DNA detected by real-time polymerase chain reaction was (1.7 × 103-3.5 × 107) copies/μg DNA in peripheral blood mononuclear cell.Among them,the outcomes were death (n =5),lost to follow-up (n =2) and T cell lymphoma (n =1).It is necessary to improve our awareness of CAEBV infection because of its poor prognosis and high mortality.
