Objective To determine whether the candidates who were disqualified for having phoria or tropia in People′s Liberation Army Air Force ( PLAAF) medical selection of flying cadets are qualified or not according to United States Air Force ( USAF) Medical Standards Directory , and to raise suggestions on revising PLAAF medical standards . Methods All the candidates who had participated in the final medical selection of flying cadets were reevaluated and determined as qualified or not according to USAF Medical Standards Directory .Results There was a marked difference between disqualification rates of PLAAF and USAF .13.87%of the candidates who were regerded as disqualified by PLAAF standards were qualified according to USAF Medical Standards Directory .These cadets might be eliminated by mistake . Conclusion The standard on heterophonies of the PLAAF is more stringent than that of the USAF .We shoucd revise PLAAF standards using USAF standards for reference .

Objective To give an empirical study on the interests claims of patients in public hospitals. Methods By questionnaire investigation, to sum up data using factor analysis and pairedsamples T test, and to compare difference between different kinds of patients using ANOVA. Results The interests claims of patients can be summed up to six factors and there is no significant difference between different kinds of patients. Conclusion At current stage, public hospitals need improve medical technique and cut down medical expenses.

Objective To explore the clinical effect of suprapubic small cut method combined with transurethral resection prostate(TURP) on the treatment of benign prostatic hyperplasia(BPH) complicated with bladder stones.Methods Sixty patients with BPH complicated with bladder stones ≥ 3 cm in the People's Hospital of Futian Affiliated to Guangdong Medical College from January 2013 to September 2014 were selected as the study group,and another 60 patients with BPH complicated with bladder stones＜3 cm during the same period were selected as the control group.The cases in the study group were treated with suprapubic small cut method combined with TURP,and the cases in control group were treated with transurethral method combined with TURP.The intraoperative indicators (including the time used for crushed stone,total operation time,blood loss,conversion to laparotomy,blood transfusion and bladder perforation),residual bladder stones and complications of postoperative were compared.Results The operations of the two groups of patients were successfully,and there was no conversion to laparotomy and either bladder perforation.The stone removal time and total operative time of patients of the study group were shorter than of the control group,the difference was statistically significant((12.20±3.55) min vs.(24.05±7.68) min,(62.31± 10.49) min vs.(82.46± 16.75)min;t =10.849,7.897;P＜0.001).The intraoperative blood loss and the cases of blood transfusion of patients of the study group were less than the control group,but the prevalence of urinary tract infection were higher(6vs.4),but the difference was not statistically significant(P＞0.05).Residual stones were more commonly in the control group than in the study group (study group:0,control group:6 cases),the difference was statistically significant(x2 =6.316,P=0.012).Conclusion BPH complicated with bladder stones can be treated by the suprapubic small cut method combined with TURP or transurethral method combined with TURP,but suprapubic small cut method combined with TURP is safer and more effective,which is worthy of popularization and application in clinic.

Objectives:To investigate the effects of verapamil on serum induced proliferation of rabbit pigment epithelial(RPE) cells so as to search for simple and effective medicine on PVR. Methods:The rabbit RPE cells(passage 2 to 5) were cultured with various concentrations of verapamil in DMEM.The effects of verapamil on the cell cycle of RPE were analyzed with flow cytometry. Results:Verapamil significantly inhibited the serum induced proliferation of RPE cells, prevented RPE from G 1 phase transiting to S phase. Conclusions:Verapamil significantly inhibits RPE cell proliferation, and it may become a promising drug on PVR.

OBJECTIVETo observe the dynamic changes of pulmonary function and inhaled corticosteroid (ICS) doses during subcutaneous immunotherapy (SCIT) with standardized house dust mite vaccine (Alutard) in children with mild to moderate allergic asthma.

METHODSOne hundred children with mild to moderate allergic asthma were randomized into SCIT group and control group for treatment with SCIT plus ICS and with ICS only, respectively. The pulmonary function and ICS doses were evaluated before and every 3 months during the 2 years of treatment.

RESULTSNo significant difference was found in the pulmonary functions between the two groups before the treatment (P>0.05). After 3 months of treatment, FEV1% and PEF% in SCIT group were significantly higher than those in the control group [(103.19∓2.07)% vs (97.52∓1.92)%, and (105.56∓3.21)% vs (96.35∓2.7)%, respectively]; at 21 months, FEF50% and FEF25% were significantly higher in SCIT group than in the control group [(105.69∓3.29)% vs (94.61∓3.12)%, and (106.60∓3.71)% vs (92.92∓3.31)%, respectively]. A significant difference was found in ICS doses between SCIT group and the control group after 9 months of treatment (147.14∓6.41 vs 170∓4.95 µg/day, P<0.05), and the difference increased as the treatment prolonged.

CONCLUSIONSCIT combined with ICS can improve the ventilation function of the large airways early after the commencement of treatment, but its effect on small airways can be delayed. SCIT for 2 years shows a good therapeutic effect and can reduce the doses of ICS in children with mild to moderate allergic asthma.

Objective To investigate the blood-borne occupational exposure situation of medical staffs and to analyze its risk factors in order to provide a basis for working out the protective measures of medical staffs and risk evaluation .Methods The monitoring data of medical staffs with blood-borne occupational exposure in our hospital from January 2013 to December 2015 were retrospectively analyzed for understanding the occupational exposure risk factors of medical staffs ,exposure sources ,preventive drugs , regular check-up and follow-up situation as well as the relationship between the occupational protection training and the occupational exposure occurrence rate .Results Females among occupational exposure persons were more than males during 2013-2015 ,nurses were more than doctors ,which were dominated by persons under 30 years old .The occupational exposure links were mainly pulling out needle ,followed by operation suture and medical wastes handling ;the occupational exposure mainly occurred at morning , followed by afternoon ,night was minimal .The occupational exposure occurrence rate after protection training was significantly lower than that before training ,the difference was statistically significant(P＜0 .01) .The exposure sources were in turn hepatitis B , syphilis ,AIDS and hepatitis C .No infection case occurred after 6-12 months regular check-ups and follow-up of serology and virology .Conclusion Conducting the occupational protection training for medical staffs ,strictly complying with the medical procedures and increasing the safety protective awareness can reduce the occurrence of occupational exposure and are conducive to control the occupational risk .
