The principal role of neutrophils in tissue repair has long been thought to be confined to killing bacteria and clearing necrotic tissue. However, recent studies have shown that neutrophils are also one of the sources of pro inflammatory cytokines and growth factors, such as IL 1, TNF ?, bFGF, VEGF,TGF ? 1 that probably serve as the earliest signals to activate local fibroblasts, epidermal cells and vascular endothelial cells and initiate tissue repair. It was also reported that neutrophils improved the proliferation removal of injured epithelial cells in airway and corneal epithelial cells. It is very important for the successful tissue repair that the function of neutrophils is normal.

Radiation pneumonitis (RP) is one of the most common toxicities in patients with lung cancer treated by radiotherapy,which limits the delivered dose and may thus hampers tumor control,then lowers the patients,life quality.Based on the progress of molecular biology,RP may be regarded as a continuous progression of events induced by various cytokines involving numerous cells.Researches on gene polymorphisms indicate different mechanisms in the pathogenesis of RP among different races.Besides,more studies focus on the predictive value of dosimetric parameters such as V20、mean lung dose(MLD) and biological markers such as transforming growth factor-β ( TGF-β1 ).Decreasing use of drugs which may exacerbate RP and increasing use of modern treatments may be beneficial in the prevention.Meanwhile as the respect of drug prevention,more and more emphases are being placed on the target molecule of radiation-induced injury.

Objective The study aims to assess the health education effects of popular scientific brochure with pictures on infant vulvovaginitis. Methods Parents of female child outpatients aged 0～5 years old with vulvovaginitis of our hospital were selected for health education, mainly about how to prevent vulvovaginitis. Popular scientific brochure with pictures was designed for use. Eighty six parents of female child patients aged 0～5 with vulvovaginitis were randomly divided into the control group and the observation group with 43 people in each group. In the control group, health brochures were issued and face-to-face guidance were carried out. In the observation group, popular scientific brochures with pictures were issued and faceto-face guidance were carried out Phone call investigations were done 4-8 weeks after issuing of education materials. Results Awareness rate, vulvovaginitis cure rate of their female child and satisfaction rate to education method of the observation group were significantly higher than the control group. Conclusions Health education guidance in form of popular scientific brochure with pictures can get more satisfactory effects.

Objective To investigate the changes of peripheral benzodiazepine receptors (PBRs)in rat spinal cord synaptosomes during ageing and to explore the correlation between PBRs in spinal cord synaptosomes and PBRs on platelet membranes.Methods A total of 24 Sprague-Dawley rats were divided into 3-month group and 24-month group (n=6 males and 6 females for each).All animals were sacrificed by decapitation and the spinal cords were immediately removed.Synaptosomal fractions from spinal cords were isolated by gradient centrifugation.The platelet membranes were prepared from venous blood by the method of hypotonic haemolysis.The specific binding of the radioactive PBRs antagonist [3H]PK11195 to membranes was determined.Results No significant differences in [3H] PK11195 binding activity in spinal cords and platelet membranes were observed between male and female rats in the same group (all P＞0.05).[3H] PK11195 binding activity in spinal cords and platelet membranes were higher in 3-month group than in 24 month group [(213.94±10.65) fmol/mg pro.vs.(50.65± 2.74) fmol/mg pro.,(104.97± 2.24) fmol/mg pro.vs.(56.20±5.36) fmol/mg pro.,respectively,t=51.418,29.041,both P＜ 0.001].There was a positive correlation between [3H]PK11195 binding activity in platelet membranes and in spinal cord synaptosomes (r=0.985,P＜0.001).Conclusions The level of PBRs is gradually decreased in rat spinal cord synaptosomes with ageing.[3H] PK11195 binding activity of platelet membranes can reflect the changes of PBRs in spinal cords.

Objective To evaluate the osteogenic potential of selected exercises and determine which one has the greatest value for the elderly.Methods Twenty healthy old subjects were recruited in the study.Each subject performed the following four exercises in random order:stepping onto a 4-in riser (STEP),sit-to-stand (STS),jumping (JUMP) and marching (MARCH).The subjects performed successively each of the 4 exercises for 1 minute,with an interval of 3 minutes between each.The Vicon action capture system was used to record the peak ground reaction of the subjects during their exercises.The osteogenic index (OI) was calculated by the formula:OI=peak GRF/ (body weight×9.8) × In (number of loading cycles±1).Results JUMP and MARCH had superior OI value (7.52 ±2.06,6.51 ±1.59) than STEP (5.22 ±0.63) among the4 exercises (P＜0.05).STS was found to have the lowest OI (2.23 ± 0.42) in the elderly.There was no significant correlation between the height and OI in JUMP and MARCH (P ＞0.05).Conclusion STEP and MARCH had the higher OI value and could be deemed as the better ways to induce positive effects on bone health in the elderly population.

Over the past decade , with the rapid increase of the incidence of idiopathic membranous nephropathy (IMN) in our country, the diagnosis and treatment of IMN has been paid more and more attention.IMN is an autoimmune disease.Two important podocyte autoantigens , PLA2R and THSD7A, have been indentified sine 2009.Subsequently , serum anti-PLA2R antibody test and anti-THSD7A antibody test have also been used in clinical .Preliminary applications show that these two tests can not only help IMN diagnosis and differential diagnosis , but also help IMN prognosis.

Objective To compare the clinical effect of craniotomy versus sphenotresia drainage for treatment pa?tients with hypertensive cerebral hemorrhage. Methods Retrospective analysis the patients with hypertensive cerebral hemorrhage in our hospital, and divided into the group of craniotomy(n=39) and the group of sphenotresia drainage(n=50). The operating time, hematoma clearance rate, complications after operation and intracranial pressure at 4h, 24h, 48h, 72h, 5d and 7d after operation between the two groups were record. Results The intracranial pressure in both groups are raised gradually in the 48 h after surgery and gradually declined at 48 h after surgery. The increasing amplitude in craniotomy group is less than the group of sphenotresia drainage. Between the two groups of group, different point, and between groups and the interaction of the different point difference had statistical significance (P<0.05). The hematoma clearance rate in the group of craniotomy is less than the group of sphenotresia drainage. However, the operating time and the infection rates in the group of craniotomy is greater than the group of sphenotresia drainage, the difference is statistically significant (P<0.05). Conclusion Craniotomy can increase the hematoma clearance rate, decrease intracranial pressure as well as the oc?currence of rehaemorrhagia, however, it also will prolong operation time and increase the risk of lung infection and gastro?intestinal bleeding. It is depend on the general characteristic of patients to determine which operation methods to adopt.

Objective To study the effect of arthroscopy in conjunction with minimally invasive percutaneous plate osteosynthesis (MIPPO) in the treatment of tibial plateau fracture.Methods 78 cases of tibial plateau fracture patients admitted during March 2011 and June 2014 were retrospectively analyzed, with 38 cases given the conven-tional open reduction treatment (group A) and 40 given arthroscopy in conjunction with MIPPO (group B).The clini-cal efficacy, Rasmussen excellent rate and good rate, and postoperative complications in both groups were then com-pared.Results The operative time showed no significant difference in both groups (p >0.05); the time of hospital-ization, the length of surgical incision and healing time of group B were significantly better than group A (p <0.05);after follow -up observation, Rasmussen excellent rate and good rate of group B were significantly higher than group A (p <0.05).Conclusion Arthroscopic in conjunction with MIPPO has the advantages of smaller surgical wound, faster recovery and fewer complications, and have good efficacy and better clinical value for the treatment of tibial plateau fractures.
