OBJECTIVETo investigate clinical curative effects of gluteal muscle contracture release combined with insertion of gluteus maximus tendo-chilles lengthening with Z-shaped in treating severe gluteal muscles contracture.
METHODSFrom 2006 May to 2011 May, 20 patients (35 sides) with severe gluteal muscle contracture were collected, including 12 males and 8 females, aged from 8 to 34 years old with an average of 13 years old; the courses of disease ranged from 3 to 21 years. All patients manifested abnormal gait at different degree, knees close together cannot squat,positive syndrome of Ober, positive test of alice leg. Gluteus contracture fascia release were performed firstly in operation, then insertion of tendo-chilles lengthening with Z-shaped were carried out. Preoperative and postoperative gait, and knee flexion hip extensor squat test, cross leg test, adduction and internal rotary activity of hip joint, stretch strength and motor ability after hip abduction were observed and compared.
RESULTSTwenty patients were followed up for 1 to 5 years. Gluteus maximus were released thoroughly, and snapping hip was disappeared, Ober syndrome were negative. There was significant differences in knee flexion hip extensor squat test, adduction and internal rotary activity of hip joint,stretch before and after operation (P<0.01). Gluteus muscle strength was protected,stretch strength and motor ability of hip joint were recovered well. Among them,31 cases got excellent results and 4 good.
CONCLUSIONFor severe gluteal muscles contracture,insertion of gluteus maximus tendo-chilles lengthening with Z-shaped performed after gluteus contracture fascia release could release gluteal muscle contracture to the greatest extent and obtain postoperative curative effect without resection of normal hip muscle fibers and destroy joint capsule.

Objective To obtain the short peptides from phage-displayed random peptide library through screening the epitope of monoclonal antibody against tumor necrosis factor(TNF-?). Methods Anti-TNF-? was used to immunoscreen a phage random peptide library of 12 amino-acidresidues displayed as a fusion to protein Ⅲ of filamentous phage M13. The positive clones were obtained by three rounds of biopanning, and the reactivity of each clone binding to anti-TNF-? was examined by double-antibody sandwich ELISA and Dot-ELISA. Mixed positive phage clones were used to detect the serum from SLE patients and healthy persons by Dot-ELISA. Results The eluted phages were enriched nearly 100 fold through three rounds of biopanning, 7 phage clones from the third round biopanning were randomly selected and 5 clones of them could bind to the anti-TNF-?. The binding rate of mixed clones with SLE patients was significantly higher than that of healthy persons. Conclusion The phage display technique can be applied to study the anti-TNF-? antigenic peptides, and these epitopes provide the potential for developing immunodiagnostic reagents of vaccines.

Objective:To investigate the effects of Bailing capsules on the expression of TGF-β1 in the peritoneal dialysis solution for peritoneal dialysis patients. Methods: Totally 40 patients treated with peritoneal dialysis ( PD) were randomly divided into two groups (20 cases in the control group and 20 cases in the experimental group). All the patients were treated with PD by 1. 5% perito-neal dialysis effluent (6 000 ml everyday), and the patients in the experimental group were additionally treated with Bailing capsules (5 capsules each time, three times a day after meals) for 6 months. The adequacy of PD (including Kt/V and Ccr) of the two groups was examined after the one-month treatment. The renal function and the level of TGF-β1 in the effluent in 1, 3 and 6 month were com-pared between the two groups. Results:The adequacy of PD ( Kt/V and Ccr ) had no significant difference between the two groups (P<0. 05). The level of serum creatine was decreased significantly in both groups after the one-month treatment (P<0. 05), and no significant change was shown in 3 and 6 month (P>0. 05). In the control group, the expression of TGF-β1 in the effluent in 1, 3 and 6 month was increased gradually with significant difference (P<0. 05). In the experimental group, the expression of TGF-β1 in the effluent had no significant difference in 1, 3 and 6 month (P>0. 05), which was lower than that in the control group (P<0. 05). Conclusion:Bailing capsules can decrease the expression of TGF -β1 in the effluent for the patients treated with PD and inhibit the peritoneal fibrosis.

Objective To find out the cognition understanding of iodine deficiency disorders(IDD) of target population in Xi’an City, and evaluate the effectiveness of a health education project on prevention and control of IDD. Methods By using the random number table, three towns in each project county were selected. Obeying the requirements of the education program for IDD control, the health education activities were implemented during 2007 - 2011. Before and after intervention, questionnaire was used to investigate the intervention effect. The primary school grade 5 students and women of childbearing age were included in the survey of IDD knowledge. Hierarchical random sampling method was used to select pupils and childbearing women. Results After health education, the rate of knowledge on IDD increased from 66.97%(13 321/19 890) to 93.49%(18 610/19 905,χ2 = 4 413.07, P < 0.05) among pupils, and 62.27%(6 193/9 945) to 93.96%(9 361/ 9 963, χ2= 2 924.18, P<0.05) among childbearing women. And the awareness had reached the national standard. But the survey results showed that: the rate of IDD related knowledge in rural areas was lower than that in town areas. The awareness rates of IDD in precaution, main hazards, identification of iodized salt were 46.50%(239/514), 55.25%(284/514) and 50.97%(262/514) among pupils in rural areas and 61.44%(376/612), 65.69%(402/612) and 70.59%(432/612) among pupils in town areas, and the awareness rates of pupils in rural areas were lower than those of pupils in town areas. Thirty-six point ninety-three per cent(226/612) of the pupils in towns and 35.60%(183/514) of the pupils in rural areas told this information to their parents. The awareness rates of IDD in precaution, main hazards, IDD prevention day were 49.25%(197/400), 50.75%(203/400) and 36.50%(146/400) among women in rural areas and 75.44%(298/395), 80.25%(317/395) and 57.97%(229/395) among women in town areas, and the rates of women in rural areas were lower than those of women in town areas. The rate of consciously purchasing of qualified iodized salt was 51.75%(207/400) and the consumption rate of iodized salt was 36.75%(147/400) among women in rural areas, which were 73.42%(290/395) and 43.80%(173/395) among women in town areas, and the rates in rural areas were lower than those in town areas. Conclusions Before health education of IDD, the rate of IDD related knowledge in Xi’an City is poor, rural areas are lower than town areas. Health education project is effective in promoting the understanding and grasp of IDD knowledge.
