0.05).Conclusions The serum concentrations of cortisol,GH,IGF-Ⅰ and IGFBP3 in children suffered from asthma have no obvious change before and after 24 months long-term inhaled corticosteroids.The height changes before and after therapy have no significant difference between observation group and control group with same age and gender.

Objective To explore the effect of Okam on airway inflammation in asthmatic mouse.Methods Thirty-two SPF grade Kunming Strain mice were randomly divided into positive control group,glucocorticoid inhalation group,Okam group and negative control group with 8 mice in each group.The mice were sensitized and repeatedly challenged with ovalbumin(OVA) to establish the models of chronic asthma.The glucocorticoid group were given Budesonide(200 ?g) and saline everyday by inhalation,the Okam group were given 50 mg/kg Okam by gavage,and the positive group had saline at the same time,the negative control group received saline at all stages.The inflammation of the lung tissue were scored underwent HE staining.Bronchoalveolar lavage fluid(BALF) cell count and differential were studied,and interferon-?(IFN-?),interleukin-4(IL-4) in BALF were determined by enzyme-linked immunosorbent assay(ELISA).Results There were no inflammatory cell infiltrate of bronchiole in the negative control group.Inflammatory infiltration of lung tissue were obvious in the positive control group.Inflammatory infiltration of lung tissue lightened obviously in the Budesonide and Okam groups.The total cell number,Eosinophils(EOS) and IL-4 level in BALF,and the score of the lung tissue in Okam group were all markedly lower than those in positive control group(t=5.942,7.089,7.078 Pa0.05),IFN-? lower(t=4.275 P

Objective To study the effects of different glucocorticasteroid(GCS) inhalation regimens for remissive children with asthma. Methods Three hundred and twenty - three patients with moderate asthma were enrolled on a 12 - week randomized parallel group remissive treatment after a 4 - week baseline treatment. During the baseline treatment terbutaline sulfate 250 ?g tid a day and bud esonide 200 ?g twice a day were given, and oral bronchodilators were used if necessary. The remissive treatment were composed of budesomde inhabit ion 100 ?g once a day (group A), 100 ?g twice a day(group B) and 200 ?g once a day(group 0). Patients subsequently returned to the clinic for 3 additional clinic visits (4,8 and 12 weeks) or telephone visits . On every clinic visit, the daytime and nocturnal time seventy score were recorded and spirometry was conducted in patients who were capable of performing the maneuver. Results Ultimately, 323 children were enrolled on the baseline treatment and 281 (87%) children achieved clinical remission. The rate of compliance decreased gradually during the remissive treatment, but in group B(P

OBJECTIVETo investigate the effect and its possible mechanisms of Danhong Injection (DHI) on cerebral injury during coronary artery bypass graft (CABG) operation with hypothermic cardiopulmonary bypass (CPB).

METHODSFifty patients went to CABG with CPB were randomly assigned equally to two groups, the control group and the tested group. DHI 1.5 mL/kg was pumped to where the tested group at the times of aortic pre-charging and unclamping respectively, but to the control group, equal volume of normal saline was given instead. Blood samples were taken from jugular bulb at different time points, i. e. before operation (T1, baseline), re-warming to 36 degrees C (T2 ), 30 min (T3 ) and 6 h (T4) after terminating CPB, for determination levels of superoxide dismutase (SOD) activity using xanthine oxidase method, malondialdehyde (MDA) concentration using thiobarbituric method, tumor necrosis factor alpha (TNF-alpha), as well as interleukin-6, -8 using radioimmunoassay and -10 (IL-6, IL-8 and IL-10) using ELISA.

RESULTSLevel of SOD activity significantly decreased during (T2) and after CPB (T3 and T4) in the control group, as compared to the T1 (P < 0.01), but it was unchanged in the tested group; level of MDA increased during and after CPB in both groups (P < 0.01), but more significantly in the control group (P < 0.05), so comparison after CPB between the two groups showed a higher SOD and lower MDA level in the tested group. Plasma levels of TNF-alpha, IL-6, IL-8 and IL-10 significantly increased in both groups after CPB (T3 and T4, P < 0.01) as compared to the T1, but the comparison between groups showed lower plasma TNF-alpha, IL-6 and IL-8 levels at T3 and T4, and higher IL-10 level at T4 in the test group (P < 0.01). All patients had stable life signs with no occurrence of adverse reaction.

CONCLUSIONDHI has obvious protective effect on cerebral injury in patients undergoing CABG with CPB, the mechanisms may be associated with the actions of anti-oxidation, anti-inflammation and regulation on immune factors.

BACKGROUND:Large volume of bone can be harvested by the reamer-irrigation-aspirator (RIA), which can be used for autologous bone graft, because there are many stromal stem cells and a variety of osteogenesis factors in the harvested bone. OBJECTIVE:To introduce the application progress of the RIA. METHODS:PubMed database was retrieved by the first author for RIA-related articles published from January 2000 to May 2017 using the keyword of "reamer-irrigator-aspirator". A total of 87 articles were searched initially and finally 38 articles met the inclusion criteria. RESULTS AND CONCLUSION:Compared with harvesting bone tissues from the iliac bone, the RIA can harvest more autologous bone tissues with more bone marrow stromal stem cells. Moreover, the osteogenic effect of the harvested autologous bone is better and there are fewer complications. Therefore, the RIA has been widely used as a method of harvesting non-structural autologous bone tissues. Removal of intramedullary lesions by the RIA is used in the treatment of long bone infection, osteomyelitis and bone tumors, as well as in the removal of intramedullary cement. RIA was originally used as a special reaming during intramedullary nailing for femoral shaft fractures, which could reduce high pressure and high temperature so as to decrease the risks of fat embolism and osteonecrosis. To conclude, the RIA can achieve satisfactory outcomes and result in few complications, but the clinical use is still limited by high cost, frequent fluoroscopy, bleeding and limited indications, as well as risks for iatrogenic fractures and perforation.

OBJECTIVETo explore operative complications of photoselective vaporization of prostate (120 W) for treatment of benign prostatic hyperplasia (BPH).

METHODSThe clinical data of 186 cases who underwent photoselective vaporization of prostate (120 W) for the treatment of BPH from May 2010 to April 2012, was statistically analyzed.

RESULTSThe operative time ranged from 7 to 147 minutes, and the average time was (37.7 ± 21.5) minutes. No patient accepted intraoperative blood transfusion, and occurred transurethral resection syndrome or capsular perforation. The time of postoperative indwelling catheter ranged from 1 to 11 days, and average time was (4.3 ± 2.2) days. Surgical outcome was satisfactory. Early postoperative complications included bladder spasm (3 cases), transient dysuria (19 cases), urinary tractirritation (94 cases), secondary hemorrhage (26 cases), transient urge incontinence (19 cases), all cases were relieved after treatment. Long-term complications, including recurrence (1 case), bladder neck stenosis (2 cases) and urethral stricture (2 cases), who had required reoperation. Postoperative patients with international prostate symptom score (29.4 ± 3.4), maximum urinary flow rate ((6.0 ± 1.6) ml/s) and residual urine ((167 ± 150) ml) had improved (t = -76.0 - 61.4, P < 0.01).

CONCLUSIONSWith less invasive, less bleeding and rapid postoperative recovery, photoselective vaporization of prostate (120 W) is a safe and effective minimally invasive treatment techniques for BPH. But there is still some complications after surgery and proper handling is required.
