This paper reports the diagnosis and treatment of one rare case of thyroid dysfunction caused by Strongyloides ster-coralis infection.

This paper expatiates the relationship between environmental quality of teachers and the environment education and interprets the environmental quality of teachers in colleges and universities as follows:one-sided understanding of environmental awareness,unenlightened teaching concepts,a lack of knowledge of the environment,limited teaching conditions and low environmental protection skills.The writer believes that strengthening the construction of teaching staff is the key to promoting environmental education in depth,and thus he raises some concrete measures and suggestions.

Objective To investigate the dynamic changes in each radical line of pelvic floor levator hiatus in female with stress urinary incontinence(SUI). Methods A retrospective analysis of MR images was performed in 30 female patients with clinically diagnosed SUI and 30 asymptomatic female volunteers recruited as reference group. All of the subjects underwent pelvic MRI scanning both in static statusand Valsalva maneuver, respectively, Valsalva was performed by attempt to forcibly urinate while holding her breath, respectively. Area of pelvic diaphragm hiatus (LHA), ntero-posterior length (LHL) and tmixmum width (LHW) were measured in horizontal axis plane of the obtained images.H line distance was measured in the midsagittal plane. Independent sample t test was performed to compare the difference in LHA, LHL and LHW between two groups. Paired t test was used to compare difference in LHA, LHL and LHW between two groups in static status and Valsalva maneuver, respectively. Results In static status, the values in LHA, LHL, LHW and H line distance for SUI groups were(28.7±19.3) cm2, (7.1±2.2) cm, (4.7± 1.6 ) cm and (5.7±1.1) cm, respectively. The parameters for the reference group were(13.1±3.7)cm2, (5.3± 0.8) cm, (3.4 ± 0.5) cm and (5.7 ± 0.9) cm, respectively. The difference in LHA, LHL, LHW between two groups was statistically significant (t=4.33, 4.36, 4.23, and P<0.01 for all indexes), whereas the difference in H line distance between two groups was no statistically significanct because of P> 0.05. In Valsalva
maneuver, LHA, LHL, LHW and H line distance were (40.0±26.0) cm2, (8.0±2.3) cm, (6.0±2.5) cm and (6.1± 1.5)cm for SUI group, and were (16.2±6.2) cm2,(5.5±1.0) cm, (3.6±0.8) cm and (6.0±1.0) cm for the reference group, respectively. The difference in LHA, LHL and LHW between two groups was statistically significant, (t=4.88, 5.36, 4.91 respectively, and P<0.01), whereas the differencein H value between two groups was no statistically significant (P< 0.05). For SUI group , the difference of LHA, LHL and LHW between static status and Valsalva maneuver had statistically significant with P<0.01. For reference group, the difference of LHA and LHL between static status and Valsalva maneuver had statistically significant(P<0.05). Conclusion Dynamic and static pelvic MRI can evaluate the morphology and variation of pelvic floor levator hiatus much intuitively and accurately. pelvic floor levator hiatus becomes enlarged in female with SUI.

AIM: To compare the efficacy and safety of bevacizumab with mitomycin ( MMC ) in augmenting trabeculectomy for glaucoma.
METHODS: Databases including PubMed, CBM, CNKI, VIP and WanFang Data were electronically searched for all randomized controlled trials ( RCTs) about comparing the efficacy and safety between bevacizumab and MMC in augmenting trabeculectomy for glaucoma before the date of Jun. 2016. Two reviewers independently screened literatures according to the inclusion and exclusion criteria, and evaluated the included studies. Then, Meta-analysis was performed.
RESULTS: A total 4 RCT involving 286 eyes ( 143 for bevacizumab group, 143 for MMC group) were included. The results of Meta-analysis showed that there was no significant difference between bevacizumab and MMC in the last follow-up after surgery in IOP (WMD=2. 21, 95%CI: -0.17 to 4.58, P=0.07), complete success rate (OR=0. 69, 95%CI:0. 26 to 1. 81, P=0. 45) and the numbers of anti-glaucoma medicine ( OR= 0. 12, 95%CI: -0. 15 to 0.39,P=0. 39). And there was no significant difference between bevacizumab and MMC in postoperative complications:hypotony (OR=0.7, 95%CI:0.12 to 4.05, P=0.69), bleb leak (OR=1, 95%CI: 0. 21 to 4. 74,P=1), encapsulated bleb (OR=1. 15, 95%CI: 0. 38 to 3. 44, P=0.81), choroidal detachment (OR=1. 22, 95%CI: 0. 29 to 5.22, P=0. 78) and cataract (OR=1. 15, 95%CI: 0. 38 to 3.44, P=0. 81).
CONCLUSION: Bevacizumab and MMC in augmenting trabeculectomy for glaucoma have similar efficacy and safety. Bevacizumab can't result in better outcome in term of IOP reduction. Clinicians should choose suitable solution according to disease characteristics.

Objective To investigate the MRI features of urethral sphincter in female with stress urinary incontinence(SUI) by the study of the indexes of the thickness of middle urethral sphincter, the function urethral length and bladder neck funnel . Methods Forty patients of female patients diagnosed as SUI by clinical were retrospectively as SUI group, and 40 asymptomatic female volunteers were recruited as reference group. All of the subjects were tested by pelvic MRI scanning both in static status and in the condition of Valsalva. The thickness of middle urinary sphincter was measured in the horizontal axis plane. In the midsagittal plane, the function urethral length was measured from the internal orifice to perineal fascia. The bladder neck funnel whether exist was observed from the midsagittal plane. For the comparison of the urinary sphincter thickness and urethral length of the two groups, independent sample t test was adopted. For urethral length in static status and under the condition of Valsalva, paired t test was done. For comparison of positive rate of the bladder neck funnel, Chi?squared test has been done. Results The value of the middle urinary sphincter thickness in the groups of SUI and reference were (2.23±0.68) mm and (2.69± 0.75) mm, respectively. Thus the differences of the two groups had statistical significance (t=-2.839, P<0.01 ). In the static status, the urethral length in SUI and reference group were (2.72±0.51) cm and (2.94± 0.34) cm respectively, wheras in Valsalva condition, the value were (2.33 ± 0.49) cm and (2.43 ± 0.43) cm respectively. The differences of the two groups had statistical significance in static status (t=-2.322, P=0.023), wheras there had no statistical significance in the two groups in Valsalva condition (t=-1.049,P=0.297). For SUI and reference group, both in static status and Valsalva condition, the difference of function urethral length had statistical significance (P< 0.01). The positive rate of bladder neck funnel for SUI was 72.5% (29/40), and for reference was 22.5% (9/40), the difference of the two groups had statistical significance(χ2=20.050, P<0.01). Conclusion For female SUI patients, urinary sphincter muscle is much thinner, function urethral length is much shorter and has higher positive rate of bladder neck funnel.

Objective To investigate the occupational burnout status of rehabilitation therapists in medical institutions and analyze relat-ed factors. Methods From December, 2015 to February, 2016, a total of 264 rehabilitation therapists, selected with random cluster sampling method, were investigated with Maslach Burnout Inventory-General Survey (MBI-GS) in Bengbu, China. Results The detection rate of ther-apist burnout was 81.1%, and the average score was (3.13±1.07). There were significant differences in the score of occupational burnout and its three dimensions (P<0.05), except emotional exhaustion dimension among different ages (P>0.05). Multiple regression analysis showed that the gender, age, marital status, educational background, professional title, shift work, job demand, job autonomy, social support, de-mand-autonomy ratio and income levels were the factors related with occupational burnout. Conclusion Rehabilitation therapists generally feel occupational burnout. It is different with demographic characteristics and working conditions.

Objective To investigate the association of the Glu298-Asp(894G→T)mutation at exon 7 of the endothelial nitric oxide synthase gene and acute myocardial infarction.Methods By using the designed primers based on flanking sequences of the Glu298-Asp mutation at exon7 of eNOS, 894G→T fragments were amplified by nested PCR from genomic DNA of healthy control and AMI subjects, digested by restriction enzyme after amplification and detected by agarose gel electrophoresis for 894G→T genotyping. To count the genotype and allele frequencies, the significance of difference in the genotype and allele between two groups were assessed by statistical analysis.Results Three genotypes containing GG, GT, TT were identified on the 894 site of the eNOS gene exon 7 in both AMI and controls. In AMI group, there were 25 patients having 9 homozygotes, the other 16 having heterozygotes. In controls, there were 13 cases with G894T mutation,all having heterozygotes. The mutation frequency of TT homozygote allele has extraordinary significant difference between two groups (P
