This paper reports a study of three components of stature for a sample of 605 healthy children aged 8-15. Suprapelvic height, pelvic height, and subischeal height are obtained by calculation on the basis of standing height, sitting height, total lower limb length, ankle height and bi-iliac width. By statistical analysis, sexual dimorphism is revealed in both suprapelvic height and pelvic height. The increase in pelvic height is greater in girls than boys, and occurs before the appearance of secondary sexual charateristics. The relationships between suprapelvic height and idiopathic scoliosis, and between pelvic height and low back pain are discussed.

0.05).Conclusion Acupuncture has an effect on I/O curve amplitude of EPSP and PS,and on LTP induction of PS of dentate gyrus(DG) in rats after cerebral ischemia.However,the difference of effect of acupuncture at different doses on LTP induction is insignificant.

Objective To explore the levels of serum 25(OH)D in glomerular disease patients and investigate its influence on the impaired glucose metabolism after treated with glucocorticoid. Methods A total of 61 patients with glomerular disease confirmed by clinical diagnosis and renal biopsy were included in the case group before receiving steroid therapy. 16 cases were selected as control at the same period. Before and six weeks after the treatment of glucocorticoid, all subjects took oral glucose tolerance test (OGT). According to the results of OGT, patients were divided into normal glucose regulation (NGR) group, impaired glucose regulation (IGR) group and steroid diabetes mellitus (SDM) group. Serum 25(OH)D levels were detected with enzyme?linked immunosorbent assay (ELISA), and other clinical data including albumin(Alb), Scr and urine protein were collected. Results (1) Before treated with glucocorticoid, the serum 25(OH)D levels in the control group [(64.09±13.53) nmol/L]were significantly higher than that in NGR group [(50.81 ± 12.44) nmol/L], while the latter was significantly higher than that in IGR group [(42.71 ± 8.09) nmol/L, all P<0.05]. In the glomerular disease patients, 18 cases (29.51%) were 25(OH)D insufficiency and 39 cases(63.93%) were 25(OH)D deficiency. 25(OH)D levels in patients with nephritis were significantly higher than in patients with nephroitic syndrome[(56.94 ± 10.41) nmol/L vs (45.88 ± 11.55) nmol/L, P<0.05]. (2)6 weeks after the treatment, incidence of steroid diabetes in IGR group was significantly higher than that in NGR group (61.11% vs 20.93%, P<0.05). Baseline levels of 25(OH)D in NGR group and IGR group were all significantly higher than that in SDM group [(55.68 ± 13.09) nmol/L, (48.97 ± 9.91) nmol/L vs (40.91 ± 7.82) nmol/L, all P<0.05]. (3)Serum levels of 25(OH)D were positively correlated with serum albumin and serum calcium, and negatively correlated with BMI, urinary protein, cholesterol and the 2 hours postprandial blood glucose. (4)Logistic regression analysis indicated that 25(OH)D<50 nmol/L and HbA1c>5.6% increased the risk of developing steroid diabetes 5.586 and 5.197 times, respectively. Age increased 10 years or insulin resistance index increased one, the risk of occurred SDM increased 2.443 and 2.755 times, respectively. Conclusions Most glomerular disease patients are serum 25 (OH)D deficiency or insufficiency. Low level of serum 25(OH)D is one of the main risk factors of steroid diabetes in patients with glomerular disease when treated with glucocorticoid.

Objective To evaluate the efficacy of transpubie access using pedicle tabularized la-bial urethroplasty for urethral reconstruction in female patients with urethral strictures associated with urethrovaginal fistulas.Methods Eight cases of urethral strictures were treated using pedicle labial skin flaps for urethral reconstructions.All cases were the mid-urethral strictures associated with ure-throvaginal fistulas.A single face pedicle flap was obtained from the labia minus or majus in 5 women,and double face pedicle labial flaps were used in 3 patients.Results There were no serious complica-tions.Two patients complained of dysuria symptoms for 2 weeks and one patient experienced stress incontinence which resolved after 4 weeks.The patients were followed up for 6 to 130 months (mean 52) postoperatively.All patients had normal micturition following catheter removal with urinary peak flow greater than 15 ml/s(17.4-42.0 ml/s).Conclusion Pedicle labial urethroplasty might be a reliable technique for the management of complex urethral strictures associated with urethrovaginal fis-tulas.

Objective This study was to discuss various operative approaches for the repair complicated posterior urethral strictures. Methods 34 patients with posterior urethral strictures and associated ure-throrectal fistulas (URFs) were reviewed. The etiology of urethral strictures and fistula was due to pelvic fracture in 26 patients, iatrogenic in 6 cases and fall injury in the remaining 2 cases. The patients were treated by using a simple perineal approach (4 patients), a transperineal inferior pubectomy approach (21 patients) and combined abdominal transpubic perineal approach (9 patients) and URF repair and anastomotic urethroplasty were performed simultaneously in all cases. Results One-stage repair was successful in four patients (100%) using a simple perineal approach, in 19 of 21 (90. 48%) using the transperineal-inferior pubectomy approach and 7 of 9 (77. 78%) using the transpubic-perineal approach. Of the 34 patients, recurrent urethral strictures developed in two cases, recurrent URFs developd in two patients. Conclusions Surgical approaches for the special complex urethral strictures should be based on the location of the URF, its etiology and length of the urethral strictures, as well as a history of previous repairs. The transperineal-inferior pubic approach may be appropriate as a first-line procedure.

Objective To analyze the MRI features of Hirayama disease(HD)with cervical natural position and its diagnostic val-ue.Methods The natural position of cervical vertebra with MRI examination was used in 1 5 patients and 40 normal people.The spe-cificity and sensitivity of MRI features were analyzed and the ratio of cervical sagittal diameter/cervical transverse diameter (CSD/CTD)of the lower cervical cord was measured.Results CSD/CTD of the patients and control group had a significant difference (t=7.99,P =0.00).The sensitivity of LOA was 86.7%,and its specificity was 88.4%.The sensitivity of atrophy of the lower cervical cord was 80.0%,and its specificity was 79.5%.The sensitivity of the cervical spine curvature abnormalities was 40.0%,and its spe-cificity was 65.2%.The sensitivity of abnormal signal in the spinal cord was 46.7%,and its specificity was 87.5%.The sensitivity of abnormal signal in the epidural outer cavity was 20.0%,and its specificity was 96.8%.Conclusion MRI features of lower cervical cord in combination with clinical symptoms and signs can be helpful for the accurate diagnosis of HD.

Objective To summarize the experience and evaluate the efficacy of treatment of urethral stricture using direct visual internal urethrotomy (DVIU).Methods The clinical data of 361 patients (age range 16 -72 years, mean age 38 years) with urethral stricture who underwent urethrotomy from 1990 to 2010 was retrospectively analyzed.The disease course ranged from three months to 78 months with a mean of 16 months.The stricture length ranged from 0.2 to 2.0 cm (mean 1.1 cm).Stricture length was split into four main groups:stricture length≤0.5 cm in 63 (group 1 ), stricture length ranging between 0.6 and 1.0 cm in 175 ( group 2), stricture length ranging between 1.0 and 1.5 cm in 85 ( group 3 ) , and stricture length ranging between 1.6 and 2.0 cm in 38 ( Group 4).Of the 238 patients with length less than 1.0 cm there were 148 who's scar thickness were less than 1.0 cm, and 90 who's scar thickness were greater than 1.0 cm.Of the 123 patients with length less than 2.0 cm there were 69 who's scar thickness was less than 1.0 cm, and 54 who's scar thickness was greater than 1.0 cm.Results Three patients with DVIU failed because of long occlusion and false passage.Three hundred and twenty patients were followed-up from 12 to 120 months (mean:42).Re-openiag procedures were performed on 174 patients (54.4%) due to recurrence.The re-openiag procedure rate was 3.3%, 49.7%, 83.3% and 97.1% in Group1, Group2,Group3 and Group4, respectively.On the basis of scar thickness, of the 207 patients with stricture length less than 1.0 cm, 38 of 136 patients (27.9%) with scar thickness less than 1.0 cm underwent opening operation, and 43 of 71 patients (60.6%) with scar thickness more than 1.0 cm underwent opening operation.One hundred and thirteen patients with stricture length more than 1.0 cm, 33 of 42 patients (78.6%) with scar thickness less than 1.0 cm underwent opening operation, and 60 of 71 patients (84.5%) with scar thickness more than 1.0 cm underwent opening operation.Conclusions Good efficacy can be achieved in patients whose urethral stricture length is less than 0.5cm or whose stricture length and scar thickness is less than 1.0 cm using DVIU.

Objective To study the value of flexible cystoscopy in diagnosing posterior urethral strictures resulting from pelvic fracture and the pain score of the examination. Methods Between 2014 and 2015, 120 male patients with pelvic fracture urethral distraction defect were evaluated by cystoscopy before surgery. In this study, flexible cystoscopy was used in 87 patients, 33 patients received conventional rigid cystoscopy. The cystoscopy was introduced into the posterior urethra and the area was evaluated for the length of the proximal urethra and any possible fistulas, false passages, calculi or displacement of the posterior urethra. The patient’s pain feeling was recorded during the examination, 24 hrs after cystoscopy examination. The pain feeling result was achieved by visual analogue pain scale. Results Severe allergic reaction or obvious discomfort did not occur in any patients after cystoscopy. By comparing the data obtained from lfexible cystoscopy to those from conventional urethrography, the rate of detection in other abnormalities was higher in lfexible cystoscopy than in conventional urethrography. 21, 5, 7 and 5 patients were detected with calculus, posterior urethral structure damage, false passage and ifstula respectively. In comparison, the abnormalities were only observed in 3, 2, 3 and 1 patients respectively through conventional urethrography imaging. However, the pain feeling of the flexible cystoscopy is better than the convenional rigid cystoscopy. The statistical difference was found in the pain feeling score during the examination and later after the examination. Conclusions Flexible cystoscopy is a safe and valuable procedure in the evaluation of the posterior urethra in patients with pelvic fracture urethral distraction defect before surgery.

Objective To establish a rat model of coal-burning-borne fluorosis,and to observe the expression changes of bone morphogenetic protein-2 (BMP-2) and bone morphogenetic protein-3 (BMP-3) in the serum of rat treated with different dose of fluoride and different treatment duration.Methods A total of 120 clean grade SD rats(body mass between 80 to 120 g) weaned for 4 weeks were randomly assigned into four groups,which were control,low-dose fluorid,medium-dose fluorid and high-dose fluorid groups,respectively,and 30 rats in each group (female 15,male 15).All of the rats were fed with coal drying corn from fluorosis area.Ten rats were killed by femoral artery bleeding 30 d,90 d and 180 d after exposed to fluoride,respectively.Serum BMP-2 and BMP-3 level was tested by enzyme-linked immunosorbent assay (ELISA).Results ①Results of BMP-2:after exposed to fluoride for 90 d and 180 d,the differences of serum BMP-2 level between groups were statistically significant(F=385.08,173.98,all P ＜ 0.01).In low-dose fluorid,medium-dose fluorid and high-dose fluorid groups,the expression of serum BMP-2 at 90 d[(18.80 ± 0.43),(22.22 ± 0.85),(25.14 ± 0.69)μg/L] and 180 d[(7.98 ± 0.68),(8.97 ± 0.78),(15.04 ± 0.89)μg/L] was higher than that of control group[(12.54 ± 1.29),(7.53 ± 0.97)μg/L,all P ＜ 0.05],and the level of BMP-2 increased with increasing dose of fluoride (all P ＜ 0.05).Within each group,the difference of serum BMP-2 was statistically significant(F =55.42,511.58,686.35,671.64,all P ＜ 0.01).The expression of BMP-2 in each group at 90 d [(12.54 ± 1.29),(18.80 ± 0.43),(22.22 ± 0.85),(25.14 ± 0.69)μg/L] was higher than that at 30 d[(11.75 ± 1.15),(11.42 ± 1.07),(11.38 ± 0.92),(11.15 ±1.03)μg/L,all P ＜ 0.05].The expression of BMP-2 in each group at 180 d[(7.53 ± 0.97),(7.98 ± 0.68),(8.97 ± 0.78),(15.04 ± 0.89) μg/L] was lower than that at 90 d.②Results of BMP-3:the difference between groups was not statistically significant at every experimental stage(F =0.7215,1.2951,0.0964,all P ＞ 0.05).Conclusions Longer excessive fluoride intake stimulates the expression of BMP-2 in rats,but with prolonged fluoride intake,the stimulation becomes weak.The effect of fluoride on BMP-3 is not as sensitive as that on BMP-2.
