Abstract? AlM: To observe the effect of combining partial reduction orthokeratology ( Ortho-K ) and spectacles on slowing myopic progressionin high myopic adolescent.? METHODS: Sixty - nine eyes of 36 high myopic adolescent ( aged 9 ~15 years ) with spherical equivalent refraction ≧-6. 00 diopters ( D) ( spherical component≧-5. 50D) were fitted with custom-made four-zone/five-curve Ortho-K lenses. The target of reduction was to achieve -5. 00D for both eyes. The residual refractive errors after at least one month of Ortho-K wear were corrected with single-vision spectacles for clear vision in the daytime. The unaided visual acuity ( UVA) , refractive error ( RE ) , axial length ( AL ) , and ocular health were assessed before the Ortho-K lens wear, and followed up for 2a after Ortho-K.?RESULTS: ( 1 ) Changes in UVA: The mean UVA was 0. 09±0. 05 at baseline before Ortho-K;the mean UVA was 0. 27 ± 0. 14, 0. 54 ± 0. 18, 0. 78 ± 0. 24, and 0. 81 ± 0. 19, respectively after Ortho-K wear for l night, 1wk, 1, and 3mo. The differences of UVA were significant with baseline (P<0. 05), and became stable 1mo after the treatment. (2) Changes in RE:The mean RE was -6. 82± 0. 71D at baseline before Ortho-K and -6. 86 ± 0. 77D after Ortho-K wear for 1a (P>0. 05 compared to baseline). The mean RE was-7. 11±0. 81D after Ortho-K wear for 2a, and the amount of myopia increased -0. 29 ± 0. 37D compared to baseline (P<0. 05). (3) Changes in AL: The mean AL was 26. 18 ± 0. 57mm at baseline before Ortho-K, and it was not significantly different (P>0. 05) from the AL after Ortho-K wear for 6mo (26. 19±0. 54mm) and for 1a (26. 21± 0. 47mm). The AL was 26. 37±0. 59mm after Ortho-K wear for 2a, and the mean increase was 0. 19 ± 0. 28mm compared to baseline (P<0. 05). (4) Grade 1 corneal staining was observed in some subjects at each visit. However, the staining was improved after lens cleaning, discontinuing lens wear, or applying artificial tears. No other adverse events were reported in all subjects during the 2a study.?CONCLUSlON:Combining partial reduction Ortho-K and spectacles completely slowed myopic progression in high myopic adolescent after receiving the treatment for 1a, and partially reduced myopia progression after 2a of treatment. No severe ocular complications were found throughout the treatment. The combination treatment appeared to be effective and safe, but its long-term effect needs to be further assessed.

Objective To further understand factors that influence health-related quality of life (HRQOL) in patients with ulcerative colitis (UC),especially the role of perceived stress and coping modes in Chinese patients with UC.Methods This study was a cross-sectional study.Patients with UC were recruited from July 2013 to September 2014 in Peking Union Medical College Hospital.HRQOL was measured using the inflammatory bowel disease questionnaire (IBDQ).Perceived stress was measured by Perceived Stress Scale (PSS).Coping strategy was evaluated using Medical Coping Modes Questionnaire (MCMQ).Demographic data,course of the disease,clinical disease activity,and disease phenotype according to Montreal classification were also collected.Univariate analyses were conducted to determine which variables were associated with HRQOL,and those were statistically significant were entered into a multivariate regression model.Results We recruited 214 patients (response rate 92.2％),whose median age was 37.5 (29.0,49.3) years old and median course of UC was 4 (2,9) years.Through univariate analyses,better HRQOL was significantly associated with regular medical visits,lower number of previous relapses and hospitalizations,no steroid use,Montreal E1,lower Mayo scores,clinical remission,less perceived stress and less acceptance strategy use.However,multivariate analyses revealed that perceived stress (OR =1.112,95％ CI 1.058-1.169),acceptance (OR =0.310,95％ CI 0.141-0.685),number of hospitalizations (OR =2.924,95 ％ CI 1.328-6.437) and clinical activity (OR =5.058,95 ％ CI 2.312-11.066) were most strongly related to HRQOL.Conclusions HRQOL of UC patients are not only associated with clinical activity of the disease,but also associated with coping strategy and perceivedstress.Further research needs to focus on whether or not relieving stress and guiding patients to cope with ulcerative colitis would improve HRQOL.

Objective To evaluate the effects of Achilles tendon lengthening on talipes equinus in children with spastic cerebral palsy. Methods From December, 2013 to June, 2014, seventeen spastic cerebral palsy children with talipes equinus (34 feet) received Achilles ten-don lengthening. Ankle dorsiflexion range of motion (ROM) and surface electromyography from tibialis anterior and medial head of gastroc-nemius were measured before and 8 to 12 months after operation, respectively. ROM of passive and active dorsiflexion, root mean square (RMS) of tibia muscle group and co-contraction ratio (CR) when standing were compared. Results The ROM of ankle passive and active dorsiflexion increased (Z>4.867, P<0.001), while the RMS of gastrocnemius muscle decreased when ankle passively dorsiflex (t=4.31, P<0.001). RMS of tibialis anterior and gastrocnemius muscle changed little when standing (Z<1.291, P>0.05), while CR reduced (t=2.38, P<0.05). Conclusion Achilles tendon lengthening can improve the coordination of tibia muscle group to increase the ROM of ankle for chil-dren with talipes equinus after spastic cerebral palsy.

Objective To evaluate the diagnostic value of the recombinant protein Sj_Ts4 in immunodiagnosis of Schistosomiasis japonica.Methods Seventy-four blood samples of schistosomiasis japonica patients(acute, chronic and advanced)were used for evaluating the sensitivity.Blood samples from 24 Clonorchiasis patients,8 patients with hookworm infections and 30 normal persons from the areas without Schistosomiasis were used ror patients.Results The positivity rates were 97.1%(33/34),100.0%(16/16),87.5%(21/24)in rSj-Ts4-ELISA and 100%(34/34),100.0%(16/16),75.0%(18/24)in SjAWA-ELISA in acute,chmnic and advanced Schistosomiasis. respectively.Statistical analysis revealed no significant difference in sensitivity(X2=1.23,P＞0.05)between both recombinant and crude antigens.The false positive reaction was found to be 6.7%(2/30)in rSj-Ts4-ELISA and 3.3%(1/30)in SjAWA-ELISA when detected in 30 cases of normal control sera.but no statisticallv significant difference was noted(x2=0.35,P＞0.05).Twelve point five percent(3/24),20.8%(5/24)and 12.5%(1/8),37.5% (3/8),of cross-reactions were observed between rSj-Ts4-ELISA and SjAWA-ELISA for detecting the sera of patients with clonorehiasis and hookworms.There was no significant difference of cross-reaction in two parasitic infections (x2=0.60,1.33,P＞0.05)with the two tests.Conclusions The rSj-Ts4 antigen shows higher sensitivity and specificity for the diagnosis of Schistosomiasis japonica,which is helpful in the serological diagnosis of Schistosomiasis japonica in endemic areas.

Objective To evaluate the efficacy and safety of the improved percutaneous balloon mitral valvuloplasty (PBMV) in elderly patients with mitral stenosis. Methods Elderly patients with severe mitral stenosis received an improved PBMV which included a modified way of atrial septal puncture and technique across the mitral valve. The left atrial pressrue (LAP), mean pulmonary pressure (MPA), mean gradient across the mitral value (MPG) and mitral valve area (MVA) were recorded and compared before and after the operation. Long term follow up were made. Results After operation, the LAP decreased [(25.3±6.7) mm Hg vs.(16.4±5.8) mm Hg,1 mm Hg=0.133 Kpa], MPG decreased [(17.6±6.7) mm Hg vs.(6.8±2.9) mm Hg], MPA decreased [(38.6±12.1) mm Hg vs. (29.2±9.8) mm Hg], MVA increased [(1.05±0.22)cm2 vs.(1.61±0.38)cm2] and the New York heart association heart function classification improved. The follow-up result showed that the effect of PBMV was constant. Conclusions Improved PBMV may be an effective and safe measure for patients with mitral stenosis.

OBJECTIVETo explore the therapeutic efficacy of unilateral multiple channels approach in percutaneous vertebroplasty (PVP) for osteoporotic vertebral fractures.

METHODSA retrospective review (from March 2003 to October 2012) was conducted on 685 consecutive patients, a total of 885 vertebrae were involved. Eighty-two cases (99 vertebrae) with bone cement leakage when less than 0.3 ml bone cement was injected to fill the fracture were given PVP procedure by unilateral multiple channels approach. 38 cases were male (45 vertebrae) and 44 cases were female (54 vertebrae). The average age was 75.4 years old (from 69 to 92). The operation time, amount of injected bone cement and complications were recorded. Rate of excellent and good outcomes was studied by measuring the cement distribution on the X-ray film. The visual analogue scale (VAS) score and Oswestry disability index (ODI) system were used to evaluate the pain relief and improvement of daily activity function respectively at preoperation and 1 hour, 1 month, 3 months and 6 months after operation.

RESULTSAll these ninety-nine vertebrae were treated in 82 cases with PVP of unilateral multiple channels approach. The average operation time was 33 minutes. The rate of excellent and good outcomes of cement distribution was 98.8%. The VAS score was (8.40 +/- 0.73) before surgery,and (2.50 +/- 0.43), (2.00 +/- 0.33), (1.80 +/- 0.28), (2.10 +/- 0.17) at 1 hour, 1 month,3 months and 6 months respectively after operation. ODI was (40.94 +/- 2.72) before surgery, (9.64 +/- 2.60) at 1 month after surgery, (8.52 +/- 2.30) at 3 months after surgery and (7.77 +/- 2.15) at the final follow-up. The differences of the VAS and ODI between pre-operation and post-operation had statistical significance (P<0.01). No spine or nerve injuries occurred intraoperatively.

CONCLUSIONThe unilateral multiple channels approach in percutaneous vertebroplasty can obviously relieve the pain and effectively improve the functional activity, provide a satisfied cement distribution in vertebral body with cement leakage after a small amount infusion.
