OBJECTIVE: To investigate the efficacy outcomes of laser assisted outpatient septal spur surgery for contact point pain in a carefully selected group of patients. METHOD: This investigation included 32 patients who were selected for laser-assisted septal spur surgery in an outpatient surgical suite. All had endoscopically visible spur contact as well as nansal CT scans. Patients of sinusitis were excluded. The area of the contact point was treated with decongestant and lidocaine. If the headache completely disappeared or diminished by more than 50% in intensity, subjects were considered candidates for surgery. Headache characteristics were assessed preoperatively and at follow-up (30 months after surgery) using a standardized questionare. RESULT: Nine cases (28.1%) were free from pain at the last follow-up; 19 cases (59.4%) had their headache scores improved after surgery; four cases (12.5%) had a less than 25% reduction in their headache score. No septal perforation, hematoma, was reported. CONCLUSION For selected patients with contact point headaches, septoplasty may be useful. The positive dicaine test may indicate better effect of operation. Laser-assisted outpatient septal spur surgery for contact point pain shows good results in short-term effect, and has less complications, but long-term follow-up is required to assess its real effect.

Objective To investigate TEM and SHV ESBLs in Klebsiella pneumoniae and Escherichia coli clinical isolates from West China Hospital of Sichuan University and detect resistance of ESBLs-producing isolates. Methods The TEM and SHV ESBLs-encoding gene was amplified by PCR and was sequenced. And the MIC of eight antibiotics against the ESBLs-producing strains were detected by agar dilution. Results All strains were resistant to cefotaxime; eleven strains were resistant to aztreonam; two were resistant to ceftizidime; eleven, five and three were resistant to ciprofloxacin, amikacin and cefoxidine respectively; All strains were susceptible to imipenem. Ten strains of twelve ESBLs-producing strains carried bla SHV-2, two carried bla TEM-19. Conclusions ESBLs producers were mainly resistant to cefotaxime and aztreonam and most of them were multi-drug resistance; Cefotaxime resistance is partially due to production of SHV-2 and TEM-19 in this study.

Objective To establish standard liver volume formula of healthy Chinese and to explore if there is a correlation between changes of hepatic volume and hepatic functional reserve.Methods Two hundred and eighty healthy volunteers and 85 cirrhotics undergone serial abdominal H-CT scanning. The relation between normal liver volume measured by CT and body surface area(BSA) was studied by linear regression and correlation method, the standard liver volume formula was deduced. For cirrhotic patients, the change rate of liver volume was calculated and was compared with their Child class and postoperative complications.Results The mean normal hepatic volume for Chinese adults was (1?250?141)?cm 3. There is a positive correlation between estimated liver volume in vivo and body surface area[r=0.96, LV(cm 3)=613?BSA(cm 3)+162.8]. The mean liver volume (SD) for Child class A cirrhotics was (1?092?276)?cm 3, (868?163)?cm 3 for class B, and (652?76)?cm 3 for class C. Differences were observed among the three classes (P

Objective To observe the effects of neuromuscular activation (Neurac) training on balance and walking in children with hemiplegic cerebral palsy. Methods 30 children with hemiplegic cerebral palsy from March to October, 2015 were divided into observation group (n=15) and control group (n=15). Both groups received routine rehabilitation, while the observation group received 30-minute Neurac training in addition, 5 times a week, for 3 months. They were assessed with D and E domains of Gross Motor Function Measure 88 (GM-FM-88), balance of Fugl-Meyer Assessment and footprints analysis before and after treatment. Results The scores of D and E domains of GMFM-88 and balance of Fugl-Meyer Assessment, and the step length, step width and velocity improved in both groups after training (t>7.31, P<0.001), especially in the observation group (t>2.08, P<0.05). Conclusion Neuroac training can further promote the recovery of gross motor function, balance and walking in children with hemiplegic cerebral palsy.

BackgroundCycloplegia is well accepted for the first refraction estimate in childhood.Yet no good evidence is offered in terms of which cyclopegia is preferable for the different ages and refractive status in children. ObjectiveThis study aimed to compare the effectiveness of cycloplegia between 1％ cyclopentolate and 1％ atropine sulphate before optometry in ametropia children. Methods This was a prospective clinical trail.The self matched-pairs control randomly observation was designed.One hundred and sixty eyes of 80 children of 4-9 years old with refractive error were recruited in this study.1％ cyclopentolate eye drops were topically administered once per 5 minutes for 3 times and 1％optometry was performed 45 minutes after eye dropping.Three days after that,1％ atropine then was used 3 times per day for consecutive 3 days and again the refractive diopter was obtained.The differences of the results in autorefraction,retinoscope and residual accommodation were compared between 1％ cyclopentolate and 1％atropine eye drops.This trail was approved by the Ethic Committee and written informed consent was obtained from each custodian. Results The autorefraction values were ( 0.55 ±3.52 ) D and ( 2.22 ±3.52) D before and after the administration of 1％ atropine with the difference value( 1.66± 1.62) D (t =13.02,P =0.00 ).The autorefraction value was( 1.74±3.46 ) D after dropping of 1％ cyclopentolate and the difference value from that of 1％ atropine was (0.48 ± 0.46) D ( t =13.08,P =0.00 ).The cy(e)lplegic autorefractions of atropine and cyclopentolate have strong correlation ( R2 =0.98,P =0.000 ).The residual accommodation values were ( 0.32± 0.44 )D and(0.05±0.41 ) D after dropping of 1％ cyclopentolate and 1％ atropine with the difference( 0.27±0.55 ) D ( t =4.56,P =0.00 ).The difference value of refractive diopter was (0.31 ± 0.37 )D in myopic group,(0.56±0.48 )D in moderate hypermetropic group and(0.59±0.50)D in high myopic group,and that of myopic group was significantly lower than the moderate hypermetropic group ( t =- 3.14,P =0.00 ).No significant difference was found in the autorefraction difference between 4-6 years group and 7 -9 years group [ ( 0.61 ±0.53 ) D vs ( 0.49 ±0.39 ) D ] ( t =1.21,P=0.23 ).The hidden value because of accommodation had weak correlation with the difference value between atopine and cyclopentolate(r=0.43,P=0.00). ConclusionsBoth 1％ atropine and 1％ cyclopentolate have the cycloplegic effects.This study suggestes that 1％ atropine should be used for the optometry of hypermetropia children.

Objective To develop a multiplex PCR-based reverse line blot(mPCR/RLB) hybridization assay to detect,simultaneously,seven genes encoding AR-erm(A/TR),erm(B),mef(A/ E),tet(M),tet(O),aphA-3,aad-6 and two AR-related genes,int-Tn and mreA in group B streptococcus.Methods Nine pairs of specific primers and Oligonucleotide probes targeting erm(A/TR), erm(B),mef(A/E),tet(M),tet(O),aphA-3,aad-6 int-Tn and mreA respectively were modified according to former studies or designed in this study.The primers and probes were labeled with biotin and amino,respectively.The nine genes were amplified simultaneously in the same tube.PCR product hybridized with the probes labeled in the BiodyneC nylon membrane to detect the nine genes.To detect the sensitivity and specificity of the method developed,PCR with single pair of primer targeting each gene were tested in 318 isolates tested and the results were compared with the one abtained by RLB.Results The nine resistance-related genes could be successfully detected by mPCR/RLB assay developed in this study.Based on sequencing,21 of 22 isolates with mef had mef(E)and eight of 353 with int-Tn had an atypical sequence.Except for the above 29 genes,all the others corresponded well with the results obtained by single pair primer PCR.Conclusion The mPCR/RLB assay developed in this study is simple,rapid and suitable for surveillance of antibiotic resistance in GBS.

Background Researches showed that as the non-optical factors,cognitive has certain influence on the regulating system.So accurately experimental design is one of the key steps that evaluates the non-optical factors on regulating system.Objective The present study was to investigate the influence of presenting pattern of target and watching way on the level and amplitude of accommodative fluctuate and to analyze the effect of focus gaze of cognitive on regulating system and the relationship between focus gaze condition under near work and the development of myopia.Methods This study complied with Declaration of Helsinki,and the permission of Ethic Committee and written informed consent was obtained before entering in this trial.Thirty healthy volunteers were included with the mean age (24.80 ± 1.98) years old,equivalent refractive diopter (-1.92 ± 2.02) D and mean cylinder (-0.19±0.58) D.The presenting pattern of the targets was designed as focus gaze and relaxed gaze.The accommodative response and accommodative fluctuation in the complete corrected right eyes for the different targets at the 40 cm under the gazing state was recorded with Grand Seiko WAM 5500 automatic infrared refractor in the experiment.Results The mean accommodative response value was (1.86±0.26) D under the focus gaze and (1.27±0.39) D under the relax gaze,showing a statistically significant difference (t=-8.052,P=0.000).The mean fluctuate value was(0.17±0.06) D under the focus gaze,with a significant lowing in comparison with (0.28±0.17) D under the relax gaze (t =3.600,P =0.001).Conclusions These results demonstrate that the different presenting patterns of sighting target and watching ways of the subjects affect accommodation system.The accommodative response was relatively more accurate with a smaller microwavc moving under the focus gaze condition.

Background Even though the change in wavefront aberrations with correction modality is well documented in the literature,little is known about the underlying mechanism.Complete understanding of the causes responsible for the wavefront change in the combined lens-eye system is important since it provides basic knowledge for further improving the technique to correct refractive error by correcting lenses.Objective The aim of this study was to investigate the influence of refractive correction lens on optical property of the eye by analyzing Zernike aberrations in myopic eyes with contact lens correction.Methods This study was approved by the Ethic Committee of Wenzhou Medical College.Written informed consent was obtained from each subject before entering this study.Zernike aberrations of 52 myopic eyes of 26 subjects with the spherical equivalent-1.75 to-8.50 D were measured using a Hartmann-Shock wavefront sensor.The human eye aberrations were examined at the uncorrected condition,rigid-gas-permeable contact lens (RGP-CL) corrected condition and soft contact lens (Soft-CL) corrected condition.The differences of wavefront aberrations and Zernike coefficients were compared by repeated measurement of single factor variance analysis,and correlation of the aberration changes between uncorrected condition and RGP-CL corrected condition or Sofi-CL corrected condition,between the right eyes and left eyes in different conditions were analyzed by Pearson linear correlation.Results Mean total root-mean-square (tRMS) was (0.71 ± 0.30)μm,(0.54±0.19)μm and (0.74±0.32)μm in the uncorrected condition,RGP-CL corrected condition and Soft-CL corrected condition,with a significant difference (F =8.758,P＜0.001),and tRMS was significant declined under the RGP-CL corrected condition compared with uncorrected condition (t =2.746,P =0.008),and tRMS in RGP-CL corrected condition was significantly lower than that in Soft-CL corrected condition (t =3.428,P =0.001).The high RMS (hRMS) was (0.34±0.12) μm,(0.28 ±0.12) μm,(0.40±0.14) μm in the uncorrected condition,RGP-CL corrected condition and Soft-CL corrected condition,with a significant difference among them (F =10.681,P＜0.001).An insignificant decrease of hRMS was seen in the RGP-CL corrected condition compared with uncorrected condition (t =1.987,P=0.053),but hRMS value was significant higher in the Soft-CL corrected condition than that in the uncorrected condition (t=2.101,P=0.041) and RGP-CL corrected condition (t=4.266,P＜0.001).Compared with uncorrected condition,the axis astigmatism (C5) and spherical aberration (C12) in the RGP-CL corrected condition and spherical aberration (C12) in the Soft-CL corrected condition were significantly reduced (P＜0.05),and the absolute values of trefoil (C6),vertical coma (C7) and tetrafoil (C10) in the RGP-CL corrected condition were lower than those of the uncorrected condition,but vertical coma (C7) absolute value in the Soft-CL corrected condition was increased (P＜0.05).A significantly positive correlation was seen in the spherical aberration (C12) between the RGP-CL corrected condition and uncorrected condition (r =0.763,P＜0.001),and less significant correlation was in the secondary astigmatism (C11) between the Soft-CL corrected condition and uncorrected condition(r=0.469,P＜0.001).Conclusions Different contact lens corrected conditions exert their effects on ocular wavefront structure due to its unique interaction with the eye.RGP-CL wearing has strong modification on wavefront aberrations probably due to its molding effect on corneal surface,which reduces the bilateral symmetry.High order wavefront aberration can be modified by Soft-CL wearing.
