Background The study on eye surface damage following phacoemulsification with intraocular lens (IOL) implantation is increasingly concerned,and these symptoms were associated with dry eye and often treated by polyethylene glycol eyedrops to remit the discomfortableness.Recombinant bovine basic fibroblast growth factor (rb-bFGF) eyedrops contains neurotrophic factors, but its effect on eye surface damage is worth researching.Objective This study was to evaluate the repair effects of rb-bFGF on ocular surface injury after phacoemulsification with IOL implantation.Methods A randomized controlled trail was designed.Ninety eyes of 72 consecutive patients with age-related cataract were enrolled in Fenyang Hospital of Shanxi Province from September 2010 to August 2013 under the informed consent.Phacoemulsification with IOL implantation was performed on all the eyes, and tobramycin and dexamethasone eye drops was used for 15 days as basis therapy.According to the treatment sequence,the operative eyes were assigned to rb-bFGF eyedrops group, polyethylene glycol eyedrops group and basis therapy group.rb-bFGF drops and polyethylene glycol drops were topically administered 4 times per day since the first day after surgery for consecutive 30 days in corresponding group,and only basis therapy was maintained in the basis therapy grouply.Corneal fluorescence (FL) staining scores,breakup time of tear film (BUT) and Schirmer Ⅰ test (S Ⅰ t) without topical anesthesia were examined in 1 day before operation and 1 day,7 days, 15 days and 30 days after operation.The efficacy was intergrouply compared.Results No significant differences were seen in the demography and the relevant surface examinational outcomes among the rb-bFGF group, polyethylene glycol drops group and the basis therapy group before surgery (age : F =1.50;gender :x2 =0.336, both at ＞ 0.05;FL : F =0.31;BUT:F =0.65;S Ⅰ t: F =0.57;all at P ＞ 0.05).Compared with the before operation, FL scores were obviously increased,and BUT values were reduced and S Ⅰ t values were elavated in all the eyes early stage of surgey and then gradually improved with the lapse of postoperative time, showing significant differences (Ftime =7.83,7.32,7.17, all at P＜0.01).The FL scores,BUT and S Ⅰ t in 15 days after surgery in the rb-bFGF drops group and 30 days after surgery in the polyethylene glycol drops group was closed to those of before surgery (all at P＞0.05).However,there were still significant differences between the before and after operation in the basis were closed to those of before surgery therapy group (all at P＜0.05).In addition, significant differences were found in corneal FL scores, BUT and S Ⅰ t among these three groups (Fgroup =5.08,4.15,4.61, all at P＜0.05).In postoperative 15 days and 30 days, the S Ⅰ t values were (12.32±1.18) and (11.32±1.98) mm/5 rmin,which were significantly lower than (14.36±1.77) and (13.36±2.32) mm/5 min in the polyethylene glycol drops group and (17.25 ±2.24) and (13.25 ±2.53) mm/5 min in the basis therapy group (all at P ＜ 0.05).Conclusions The topical application of rb-bFGF combined with tobramycin and dexamethasone eyedrops can improve the dry eye-related symptoms and promote the repair of the ocular surface injury after phacoemulsification with IOL implantation,and the clinical efficacy of rb-bFGF eyedrops is better than that of polyethylene glycol eyedrops or only tobramycin and dexamethasone eyedrops.

Objective To observe the effect of pressure-protective brace with pressure-sensitive device in the early stage rehabilitation training enhance bone healing, shorten the treatment course and reduce complications,a kind of independently developed pressure-protective brace with pressure-sensitive device was utilized with quantified discontinuous longitudinal stress stimulation under doctors' regulation according to procedure. Methods The pressure-protective brace with pressure sensitive device for rehabilitation training was developed in May 2008 ,and was applied in clinics during January 2009 to June 2010. Forty elder patients,with complete clinical data, underwent Dynamic Hip Screw (DHS) internal fixation of femoral intertrochanteric fracture were were enrolled into this study. These cases were assigned into experimental group and control group with 20 patients respectively. The patients of experimental group performed lower extremity rehabilitation training wearing the pressure-protective brace. The load training of lower extremities with double crutches was modulated by doctors through regulating the threshold value of pressure in different time and different condition after operation according to the prearranged rehabilitative plan of individuation. The controls were instructed to performed lower extremity rehabilitation training in traditional way. Both the clinical healing and bone union time in all cases were evaluated according to the uniform standard. Results Total 40 patients were followed up for 13.0 - 24. 0 weeks ( average, 17.6 weeks ). Clinical healing time was 7.0 - 12. 0 weeks ( average,9. 1 weeks ) and bone healing time was 12. 0 - 16.0 weeks(average,13. 7 weeks)in experimental group. While in control group,the clinic healing time and bone union time was 9. 0 - 13.0 weeks( average, 11.3 weeks) and 14. 0 -20. 0 weeks (average, 16. 6 weeks)respectively. The Independent T-test results showed that whether clinic healing time or bone healing time presented significant differences between experimental group and the controls( P＜0. 01 ). All of the fractures in these two groups were healed at the end time of follow up without adverse complications,including fracture displacement, implant break, implant loose and failure. Conclusion The pressure-protective brace with pressure sensitive device used for quantifying rehabilitation training can enhance bone union, shorten the treatment course and reduce complications. This method further proves that discontinuous compressive stress in a certain range can stimulate fracture healing.

Objective To investigate the types,antimicrobial resistance,and disinfectant resistance of pathogens isolated from hospital environmental inanimate surfaces and hands of health care workers (HCWs).Methods Pathogens isolated from hospital environmental inanimate surfaces and hands of HCWs in intensive care units and general wards in 16 hospitals in Beijing were performed bacterial identification,antimicrobial susceptibility testing,and disinfectant re-sistance testing. The carriage of antimicrobial resistance genes and disinfectant genes in pathogens were also detec-ted.Results A total of 979 specimens were collected from inanimate surfaces and hands of HCWs in 16 hospitals,75 (7.66% )pathogenic strains were isolated,78.67% of which were gram-negative bacilli. The top 3 pathogens were Pseud-omonasaeruginosa (P.aeruginosa,n= 24),Enterobactercloacae (E. cloacae,n= 14),and Klebsiella pneumoniae (K. pneumoniae,n= 4 ). One P. aeruginosa strain was resistant to aztreonam,gentamycin,tobramycin,ciprofloxacin,and levofloxacin;One E. cloacae strain was resistant to piperacillin,7 strains were resistant to nitrofurantoin;4 K. pneumoni-ae strains were all resistant to piperacillin,2 were resistant to cephalosporins,and 1 was resistant meropenem. P. aerugi-nosahad7drug-resistantgenes,positiverateofmirwas100.00% ;E.cloacaehad4drug-resistantgenes,positiveratesof tem 1and shv were both 100.00% ;K. pneumoniae had 5 drug-resistant genes,positive rates of shv and mir were both 100.00% . The resistant rates of P. aeruginosa and E. cloacae to chlorhexidine gluconate were 4.17% and 57.14% re-spectively,to trichloroisocyanuric acid were both 50.00% ,positive rates of drug-resistant genes (qacE△1-sul 1)were 79. 17% and 57.14% respectively;K. pneumoniae had no resistance to two kinds of disinfectant,dug-resistance gene was not found.Conclusion Multiple common pathogens which can cause healthcare-associated infection exist in hospital environ-mental inanimate surfaces and hands of HCWs,which are dominated by gram-negative bacilli,pathogens had resistance to antimicrobial agents and disinfectant in different degrees.

Objective To investigate the efficacy of pranoprofen drops on dry eye of patients with Sj(o)gren's syndrome (SS).Methods This is a prospective study.Sixty-eight inpatients with dry eye in our hospital were randomly divided into the experimental and control groups.Right eyes were taken for the trial,with 34 cases in each group.The experimental group was given pranoprofen eye drops combined with polyethylene glycol eye drops.Eyes of the control group were given polyethylene glycol drops only.Corneal fluorescein staining (FL),tear film breakup time (BUT) and Schirmer test (SIT) were tested before treatment and 1,2,4 weeks after treatment by the same care giver.The levels of IL-6 and TNF-α in tears were detected by ELISA.Analysis of variance of repeated data and t test were used for statistical analysis.Results The difference of FL,BUT,SIT and content IL-6 and TNF-α in tears in the experimental group patients before treatment and 1,2,4 weeks after treatment were signifcant (F=4.65,7.53,6.43,9.96,10.87; P＜0.05),which were statistically significantly different between the experimental group and the control group patients (F=3.27,5.85,4.36,8.36,7.23; P＜0.05).One week after treatment and before treatment,the difference of BUT and SIT of the two groups was not statistically significant (P＞0.05),those of the 2 weeks after treatment were statistically significantly different [BUT of the experimental group was (11.1±2.5) s,BUT of the control group was (9.7±1.9) s,t=2.594 8,P＜0.05; the SIT of the experimental group was (7.3±1.7) mm,the SIT of the control group was (5.9±1.7) mm,t=3.571 8,P＜0.05].BUT of the two groups at 4 weeks after treatment was statistically significantly different [BUT of the experimental group was (14.4±2.8) s,BUT of the control group was (11.4±2.6) s,t=4.469 4,P＜0.05; the SIT of the experimental group was (9.9±2.1) mm,the SIT of the control group was (8.7±1.9) mm,t=2.568 0,P＜0.05].The difference of FL and IL-6 and TNF-α in tears pretreatment between the two groups was not statistically significant (P＞0.05).At week 1,2,4 after treatment,the differences between the two groups were statistically significant (tFL=4.173 9,3.190 7,4.072 6; tIL-6=2.131 5,2.316 4,5.310 1; tTNF-α=2.216 4,4.871 9,8.175 0; P＜0.05).No significant discomfort and side effects were observed in the two groups.Conclusion Pranoprofen drops can significantly improve symptoms of dry eye in patients with pSS,in particular,the repair of the cornea,may be related to the inhibition of the expression of ocular inflammatory cytokines IL-6 and TNF-α,and thus reduce the ocular surface inflammatory reaction.
