Abstract
We developed a new tool to assess the severity of osteoporotic vertebral fracture using radiographs of the spine. Our technique can be used in patient care by helping to stratify patients with osteoporotic vertebral fractures into appropriate treatment pathways. It can also be used for research purposes. PURPOSE The aim of our study was to propose a semi-quantitative (SQ) grading scheme for osteoporotic vertebral fracture (OVF) on anteroposterior (AP) radiographs. METHODS On AP radiographs, the vertebrae are divided into right and left halves, which are graded (A) vertical rectangle, (B) square, (C) traverse rectangle, and (D) trapezoid; whole vertebrae are graded (E) transverse band or (F) bow-tie. Type A and B were compared with normal and Genant SQ grade 1 OVF, Type C and D with grade 2 OVF, and Type E and F with grade 3 OVF. Spine AP radiographs and lateral radiographs of 50 females were assessed by AP radiographs SQ grading. After training, an experienced board-certified radiologist and a radiology trainee assessed the 50 AP radiographs. RESULTS The height-to-width ratio of the half vertebrae varied 1.32-1.48. On lateral radiographs, 84 vertebrae of the 50 patients had OVFs (38 grade 1, 24 grade 2, and 22 grade 3). On AP radiographs, the radiologist correctly assigned 84.2%, 91.7%, and 77.2% and the trainee correctly assigned 68.4%, 79.2%, and 81.8% of grade 1, 2, and 3 OVFs, respectively. Compared with lateral radiographs, the radiologist had a weighted Kappa of 0.944 including normal vertebrae and 0.883 not including normal vertebrae, while the corresponding Kappa values for the trainee were 0.891 and 0.830, respectively. CONCLUSION We propose a new semi-quantitative grading system for vertebral fracture severity assessment on AP spine radiographs.

Abstract
PURPOSE Lipocalin 2 (LCN2) is a newly recognized bone-derived factor that is important in regulation of energy metabolism. We investigated the correlation of serum LCN2 levels and glycolipid metabolism, and body composition in a large cohort of patients with osteogenesis imperfecta (OI). METHODS A total of 204 children with OI and 66 age- and gender-matched healthy children were included. Circulating levels of LCN2 and osteocalcin were measured by enzyme-linked immunosorbent assay. Serum levels of fasting blood glucose (FBG), triglyceride (TG), total cholesterol (TC), and low- and high-density lipoprotein cholesterol (LDL-C, HDL-C) were measured by automated chemical analyzers. The body composition was measured by dual-energy X-ray absorptiometry. Grip strength and timed-up-and-go (TUG) were tested to evaluate the muscle function. RESULTS Serum LCN2 levels were 37.65 ± 23.48 ng/ml in OI children, which was significantly lower than those in healthy control (69.18 ± 35.43 ng/ml, P < 0.001). Body mass index (BMI) and serum FBG level were significantly higher and HDL-C levels were lower in OI children than healthy control (all P < 0.01). Grip strength was significantly lower (P < 0.05), and the TUG was significantly longer in OI patients than healthy control (P < 0.05). Serum LCN2 level was negatively correlated to BMI, FBG, HOMA-IR, HOMA-β, total body, and trunk fat mass percentage, and positively correlated to total body and appendicular lean mass percentage (all P < 0.05). CONCLUSIONS Insulin resistance, hyperglycemia, obesity, and muscle dysfunction are common in OI patients. As a novel osteogenic cytokine, LCN2 deficiency may be relevant to disorders of glucose and lipid metabolism, and dysfunction of muscle in OI patients.

Abstract
This study takes Cushing's syndrome, a rare disease, as a model, and adopts the path of "Plan, Do, Check, Action" (PDCA) to explore new methods to optimize the clinical path, can improve the quality and efficiency of diagnosis and treatment of rare diseases. After sorting out the problems existing in the previous diagnosis and treatment mode, our team optimizes the path in various ways and establishes a standard operation procedure (SOP) for the new path. In the evaluation of the optimized mode, 55 patients with Cushing's syndrome were admitted to the Department of Endocrinology, Peking Union Medical College Hospital, including 19 males and 36 females, aged (41.8±14.4) years (6-68 years). The pathway group (28 cases) and the control group (27 cases) were divided according to whether they were included in the new path management at the time of admission, and the effect of path optimization was assessed in terms of time, efficacy, safety and cost. The results showed that compared with the control group, the pathway group had a shorter time of hospitalization in the Department of Endocrinology and critical tests, such as blood cortisol rhythm, low-dose dexamethasone inhibition test, and bilateral inferior petrosal sinus sampling (all P<0.05). There was no significant differences in the decrease of total cortisol after operation, the incidence of postoperative complications, and hospitalization expenses (all P>0.05). The optimized path improves the medical efficiency while ensuring medical quality, safety and no increase in cost. This study proposes PDCA path optimization for complex diseases and establishes SOP process, which provides experience in management optimization for the patient-centered and clinical path-oriented diagnosis and treatment mode of rare diseases.

Abstract
A 36-year-old woman was admitted to the Peking Union Medical College Hospital with a history of fractures for 2 years, limb weakness for 1 year, and ostealgia for 2 months. The patient's examination identified iron deficiency anemia, significantly decreased serum calcium and 25-hydroxyvitamin D3 levels, and increased alkaline phosphatase and parathyroid hormone levels. Imaging showed several typical signs of osteomalacia. Considering the history of Roux-en-Y gastric bypass surgery, the diagnosis was considered to be osteomalacia caused by a postoperative nutritional absorption disorder. The patient was supplemented with calcitriol, calcium, and vitamin D and gradually returned to normal physical activity. The bone metabolism indicators and bone density were significantly improved.

Abstract
Objective: To analyze the clinical characteristics and molecular mechanisms of 5 cases of hypoparathyroidism caused by GATA3 gene mutation. Methods: A total of 5 childhood-onset hypoparathyroidism patients with GATA3 mutation were identified from 198 hypoparathyroidism (aged ≤18 years) from 1975 to 2021 in Peking Union Medical College Hospital. Clinical data and biochemical indices of the 5 patients were collected and analyzed retrospectively. Genetic screening was conducted by targeted next-generation sequencing (T-NGS), and bioinformatics analysis was performed to analyze the underline mechanisms. Results: The medium onset age of hypoparathyroidism of the 5 patients was 0.5 (0.1, 1.3) years old, and the time duration from onset to confirmed diagnosis of hypoparathyroidism and hypoparathyroidism- deafness-renal dysplasia syndrome was (7.0±5.2) years and (15.0±5.4) years, respectively. The clinical manifestations included carpopedal spasm accompanied by seizures (5 cases), basal ganglia calcification (5 cases), cataract (1 case), deafness (4 cases), and renal malformations or absence (2 cases). The blood calcium and blood parathormone(PTH) before treatment was (1.65±0.31) mmol/L and (4.64±2.63) ng/L, respectively. The 5 patients carried different heterozygous mutations in GATA3 gene, which caused nonsense mutations, frameshift mutations and splice site mutations, respectively. All the GATA3 gene mutations of the 5 patients are classified as pathogenic or likely pathogenic by the Clin Var database and American College of Medical Genetics and Genomics(ACMG). Conclusions: Attention should be paid to genetic diseases in patients with childhood-onset hypoparathyroidism. The possibility of hypoparathyroidism-deafness-renal dysplasia syndrome should be considered in hypoparathyroidism patients with hearing loss or renal dysplasia. GATA3 gene screening is highly recommended for the confirmation of the diagnosis.

Abstract
PURPOSE Tumor-induced osteomalacia (TIO) is an acquired form of hypophosphatemia caused by tumors with excess production of fibroblast growth factor 23 (FGF23). Some reports showed that TIO patients had renal Fanconi syndrome (FS) with unidentified mechanism. In this study, we investigated the association between genetic polymorphisms of phosphate transporters in renal proximal tubules and TIO with FS. METHODS We recruited 30 TIO patients with FS (TIO-FS) as well as 30 TIO patients (TIO-nonFS) without any urine abnormalities matched by age and gender. We collected clinical manifestations and conducted targeted sequencing of SLC34A1, SLC34A3 and XPR1 genes and the association analysis between variants in TIO with FS and phenotypes. RESULTS TIO-FS group had lower levels of serum phosphate (0.44 ± 0.12 vs. 0.51 ± 0.07 mmol/L, p < 0.05) than TIO-nonFS group. Among the 16 SNPs in SLC34A1, SLC34A3 and XPR1 genes, GG/GC genotypes of rs148196667 in XPR1 and AA/TA genotypes of rs35535797 in SLC34A3 were associated with a reduced susceptibility to have FS. The G allele of rs148196667 in XPR1 decreased the risk of FS. The GGAA haplotype in SLC34A3 and GCT haplotype in XPR1 were associated with a decreased risk for FS. CONCLUSIONS The polymorphisms of XPR1 and SCL34A3 are associated with TIO patients with Fanconi syndrome. It provides novel insight to the relationship of phosphate transportation and general functions of renal proximal tubules.

Abstract
Objective: To determine the clinical features and genetic characters of patients with chronic enteropathy associated SLCO2A1 gene (CEAS). Methods: Five CEAS patients diagnosed at Peking Union Medical College Hospital from January 2012 to December 2019 were enrolled in this study. The clinical manifestations, laboratory test, radiological and endoscopic findings, gene detections, treatments and prognosis of these patients were reviewed and analyzed. Results: Five male patients presented gastrointestinal symptoms after puberty, including abdominal pain, diarrhea, intermittent melena or hematochezia, incomplete bowel obstruction, anemia, hypoalbuminemia and hypokalemia. The whole gastrointestinal tract except esophagus could be involved, especially the stomach and ileum. Intestinal lesions were characterized by multiple shallow ulcers with stenosis in the layers of mucosa and submucosa. Five patients were all accompanied with primary hypertrophic osteoarthropathy (PHO), and 1 with myelofibrosis and thoracic duct dysplasia. All patients were homozygous or compound heterozygous mutations of SLCO2A1 gene. Conventional treatment of inflammatory bowel disease and COX-2 inhibitors were ineffective. Conclusions: CEAS is an autosomal recessive genetic disease which widely involves the gastrointestinal tract, and can be associated with skin and bone involvement. There is no effective treatment for CEAS at present. CEAS is a different entity from other inflammatory gastrointestinal diseases.

Abstract
PURPOSE Primary hypertrophic osteoarthropathy (PHO) is an inherited disease characterized by digital clubbing, periostosis and pachydermia with defects in the degradation of prostaglandin E2 (PGE2). Mutations in SLCO2A1 gene-encoding prostaglandin transporter (PGT) resulted in PHO, autosomal recessive 2 (PHOAR2). The spectrum of mutations and variable clinical complications of PHOAR2 has been delineated. In this study, we investigated a Chinese PHO family with a manifestation of Bartter-like hypokalemia. METHODS Clinical manifestations were collected and genetic analyses were performed in the PHO family. RESULTS The 33-year-old male proband had severe hypokalemia due to potassium loss from the kidney, while his brother had mild hypokalemia. After being treated with etoricoxib, the serum potassium level of the patient increased rapidly to the normal range which corresponded with the reduction in his serum PGE2 and PE2 metabolite (PGEM) levels. A novel SLCO2A1 compound heterozygous mutation of p.I284V and p.C459R was identified in two PHO patients in this family. CONCLUSIONS The present findings supported that the Bartter-like hypokalemia is a new complication of PHOAR2 caused by the high level of PGE2. Etoricoxib was demonstrated to be effective for the renal hypokalemia in PHO patients.

Abstract
Objective: To investigate the glucose and lipid metabolic disorders in patients with myasthenia gravis (MG) without glucocorticoid therapy, and the relationships between insulin, insulin resistance, muscle strength, serum levels of osteocalcin, 25-hydroxy vitamin D (25OHD) and glucose and lipid metabolism. Methods: A total of 102 MG patients [(40±11) years old, 43 males and 59 females] without glucocorticoid treatment were enrolled in this cross-sectional study. Height, weight and the handgrip of dominant hands were measured. Serum levels of fasting blood glucose (FBG), 2-hour postprandial blood glucose (2 h PBG), glycosylated hemoglobin (HbA1c), fasting insulin (FINS), 2-hour postprandial insulin (2 h PINS), total cholesterol (TC), triglyceride (TG), high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C) and osteocalcin, 25OHD were detected. Insulin resistance was assessed using homeostasis model assessment of insulin resistance (HOMA-IR). Results: The proportion of impaired fasting glucose or impaired glucose tolerance, type 2 diabetes, dyslipidemia, hyperinsulinemia in male and female were 30.0%, 10.0%, 50.0%, 33.3% and 17.5%, 3.5%, 27.7%, 7.1%, respectively. Serum osteocalcin levels in male and female were 2.8 (1.7, 4.4) μg/L and 2.3 (1.3, 3.9) μg/L, respectively. And 25OHD levels in male and female were (93.5±34.9) nmol/L and (81.0±30.5) nmol/L, respectively. Handgrip of male and female was (37.0±9.4) kg and (20.5±6.3) kg. After adjusted for age, FINS (r=0.619, P<0.001), 2 h PINS (r=0.640, P<0.001), HOMA-IR (r=0.534, P<0.001) were positively correlated with 2 h PBG, and the handgrip was negatively correlated with TC (r=-0.486, P=0.026), LDL-C (r=-0.485, P=0.026) in male. FINS (r=0.352, P=0.008; r=0.300, P=0.026; r=0.646, P<0.001) and 2 h PINS (r=0.278, P=0.040; r=0.518, P<0.001; r=0.382, P=0.006) and HOMA-IR (r=0.695, P<0.001; r=0.583, P<0.001; r=0.818, P<0.001) were positively correlated with FBG, 2 h PBG, HbA1c, and the handgrip were negatively correlated with FBG (r=-0.424, P=0.016), 2 h PINS (r=-0.345, P=0.034) and positively correlated with HDL-C (r=0.389, P=0.037) in female. There was no association between osteocalcin, 25OHD and glucose and lipid metabolism. Multivariate linear regression analysis also found that there were significant relationships between handgrip, insulin, insulin resistance levels and glucose and lipid metabolic disorders. Conclusion: There was a high proportion of glucose and lipid metabolic disorders in MG patients without glucocorticoid treatment, and the mechanism may be related to insulin resistance induced by muscle weakness.

Abstract
Objective: To study the clinicopathological characteristics and immunohistochemical phenotype of phosphaturic mesenchymal tumor (PMT) . Methods: The clinicopathological data and immunohistochemical profiles were obtained retrospectively from 206 patients diagnosed with PMT at Peking Union Medical College Hospital (PUMCH) during July 2008 to September 2017, with a review of literature. Results: The mean age of PMT patients was 42 years (range 13 to 70 years), with a male to female ratio of 1.1∶1.0. All patients presented with different degree of bone pain, muscle weakness, shorten of stature, thoracic deformity and pathological fractures, with hypophosphatemia and high serum ALP. Phosphatemia returned to normal within 1 week after operation in all cases underwent complete tumor resection. The duration of osteomalacia before resection (documented in 197 cases) ranged from 20 days to 40 years (average 5.7 years). The average blood phosphorus concentration raised from 0.49 mmol/L to 0.92 mmol/L before and after tumor resection (P<0.01), with 147 cases (84.0%, 147/175) returned to normal range within 2 weeks. The rate or blood phosphorus concentration recovery in 15 days after operation was 79.6% in average, displayed significant differences between patients with complete resection and those with partial resection (85.4% vs. 21.1%, P<0.01). PMT lesions mainly involved lower extremities (55.8%), followed by head and neck (29.1%). In immunohistochemical study, all cases were positive for vimentin (100.0%), while most cases were positive for NSE (96.3%), CD56 (94.2%), FGF23(88.4%), CD68 (88.3%), D2-40 (70.9%), CD34 (23.1%), SMA (55.5%), bcl-2 (59.8%) and CD99 (47.1%). The Ki-67 positive index of tumor varied from less than 2% (51.4%), 3% to 10% (41.3%) to >10% (7.2%). Conclusions: PMT mainly occurs in lower limbs or head and neck, with unique clinical characteristics and blood biochemical indexes. The tumor expresses a variety of immunohistochemical markers, indicating the potential of multi-directional differentiation. Clinical profile, blood biochemistry testing and immunohistochemical phenotype is helpful for diagnosis of PMT.

Abstract
Objective: To explore the association between α-actinin-3 (ACTN3) polymorphism and muscle strength in postmenopausal women. Methods: Five hundred and ninety-eight postmenopausal women with an average of (62.9±7.0) years old in Dongcheng District of Beijing were included. The ACTN3 polymorphism including rs540874, rs618838 and rs2229456 were genotyped by Sequenom Mass Array to explore their associations with muscle strength. One hundred and sixty-three of them were trained with regular Tai chi movement while 271 were administered with elemental calcium 600 mg/d combined with Vitamin D 800 U/d or calcitriol 0.25 μg/d for 2 years. Association between changes of muscle strength and ACTN3 polymorphism were analyzed. Results: The rs540874 genotypes were found to be significantly associated with chair stand test[GG (9.02±3.85) s vs GA (9.27±4.14) s vs AA (9.68±5.00) s, P=0.015]. Right grip strength in women with G allele were likely to be higher compared with A allele, but it was not statistically significant (P=0.056). Multiple linear regression showed that the chair stand test of AA genotype was statistically longer than that of GG and GA genotype (β=2.639, 95% CI: 1.632-4.646, P=0.010). The associations between rs618838, rs2229456 genotypes and muscle strength of both lower and upper limbs were not significant (all P>0.05). In addition, muscle strength of lower limbs of patients with rs540874 genotyped with G allele, rs618838 genotyped with C allele and rs2229456 genotyped with A allele increased significantly after enhanced exercise and vitamin D supplementation (all P<0.05). Conclusions: The rs540874 polymorphism of ACTN3 gene was associated with the muscle function of lower limb in postmenopausal women. The improvement of muscle strength after intervention were possibly correlated with rs540874, rs618838 and rs2229456 polymorphisms.

Abstract
Objective: To explore the association of vitamin D receptor (VDR) gene polymorphisms with idiopathic hypoparathyroidism (IHP). Methods: Two hundred and three patients with IHP and 209 healthy age- and sex-matched subjects were recruited at Peking Union Medical College Hospital between December 1987 and December 2015 as case group and control group, respectively. The VDR gene polymorphisms including rs739837, rs3847987 and rs2228570 were analyzed by Sequenom Mass Array. The frequency of different genotypes and alleles was detected, then their association with pathogenesis of IHP was analyzed. The clinical characteristics, biochemical indicators were collected to explore the genotype-phenotype relationship. The role of reactions to vitamin D treatment were compared between patients with different genotypes. Results: There was no significant difference in the genotypes and allele frequency distribution of SNPs between the two groups (all P>0.05). However, in the initially-treated patients, the genotypes of rs739837 were related to serum calcium level (r=0.186, P=0.026). And patients with GG genotype of rs2228750 had higher level of urine calcium than GA and AA (277.7 mg vs 141.1 mg, P=0.024) after treating with oral vitamin D(3) and calcium. Conclusions: Functional SNPs of VDR gene including rs739837, rs3847987 and rs2228570 might be irrelevant to the pathogenesis of IHP. But the genotypes of rs739837 were related to serum calcium level, and rs2228570 may have an effect on the different responses to vitamin D and its analogues in IHP patients.

Abstract
Objective: To study the clinical characteristics of primary hypoparathyroidism in adults. Methods: The clinical data of 200 cases with adult-onset primary hypoparathyroidism in Peking Union Medical College Hospital during December 1987 to December 2015 were collected and analyzed retrospectively. Among them, 128 cases were followed up for a median period of 3 years. Results: The major manifestations at their first visits were tetany and numbness in the distal extremities(81.5%, 163/200 and 62.0%, 124/200). Thirty-two percent of the cases (62 cases) had history of seizures, and 60.9%(98/161) and 74.4%(96/129) of them were with intracerebral calcifications and cataracts, respectively.Most of subjects(155/200)had more than one year delay in diagnosis. Hypercalciuria occurred in 67.2%(86/128) of the cases during the follow-up. No significant differences in the clinical characteristics and biochemical markers between the hypercalciuria subjects and the non-hypercalciuria subjects. Renal nephrocalcinosis or stones were found in 6.5%(5/77) of the cases, and kidney function decreased in 6.6%(6/91) of the patients. Kidney function was negatively associated with age and duration of disease. Conclusions: The predominant manifestations of primary hypoparathyroidism in adults included tetany and numbness in the distal extremities and seizures. It is often misdiagnosed. Calcium supplement combined with vitamin D or its metabolites effectively relieve clinical symptoms and signs. The serum and urinary calcium levels should be monitored frequently to reduce renal complications.

Abstract
Objective: To explore tissue expression of cyclin-dependent kinase inhibitor p27Kip1 and β-catenin in multiple endocrine neoplasia type1 (MEN1)-related parathyroid tumors (MHPT). Methods: Immunohistochemistry was performed to analyze the expression of p27Kip1 and β-catenin in parathyroid glands from 31 subjects with MHPT collected at Peking Union Medical College Hospital from 2002 to 2013. Five normal parathyroid glands were used as control. Results: In MHPT subjects, nuclear expression of p27Kip1 was absent in 4 (12.9%), weak in 10 (32.3%) and moderated staining in 17 parathyroid specimens (54.8%), respectively. While, in normal subjects, the nuclear expression of p27Kip1 was observed in all subjects and was stronger than that from MHPT subjects (P=0.001). As to the expression of β-catenin, normal parathyroid showed a distinct to moderate membrane staining, a moderate to weak cytoplasmic staining and negative nuclear staining. Similarly, MHPT exhibited a marked to moderate membrane (P=0.087), a moderated to weak cytoplasmic (P=0.357), and negative nuclear β-catenin staining. Conclusions: The expression of p27Kip1 is reduced or absent in MHPT tissue, and no nuclear expression of β-catenin is observed in the tumors, which suggesting p27Kip1, but not β-catenin nuclear accumulation, play a role in the development of the tumors.

Abstract
Objective: To study the clinical characteristics of childhood- and adolescent- onset hypoparathyroidism. Methods: The clinical data of 128 hypoparathyroidism patients with onset before the age of 18 years were collected and analyzed retrospectively. Results: The predominant features of the hypoparathyroidism were carpopedal spasm (89.3%, 108/121) and seizures (66.1%, 84/127). Intracranial calcification was identified in 89.4%(101/113) of the patients. Duration is an independent predictive factor (OR=1.483, P=0.011) for intracranial calcification. All the patients were treated with calcium and vitamin D or its metabolites. Hypercalciuria was associated with serum calcium (P=0.016). Conclusions: Carpopedal spasm and seizures were the main manifestations of childhood- and adolescent- onset hypoparathyroidism. Calcium and vitamin D or its metabolites are effective. Monitoring the concentration of serum and urinary calcium is of highly importance for the prevention of hypercalciuria.

Abstract
UNLABELLED This study compares efficacy of ALN/D5600 versus that of calcitriol in osteoporotic Chinese postmenopausal women. ALN/D5600 produced greater bone mineral density (BMD) increases, greater bone turnover marker decreases, and less vitamin D insufficiency. This study provided detailed clinical information regarding ALN/D5600 treatment versus calcitriol 0.25 μg/day. The study did not evaluate fracture risk. INTRODUCTION The aim of this study is to investigate efficacy of alendronate 70 mg/vitamin D3 5600 IU combination tablets (ALN/D5600) versus calcitriol in osteoporotic Chinese postmenopausal women. METHODS This study is a 6-month, randomized, open-label, active-comparator study with 6-month extension (clinicaltrials.gov number NCT01350934) in postmenopausal women aged >55 years with osteoporosis (low bone mineral density (BMD) with/without prior fragility fracture). Patients were randomized to ALN/D5600 once weekly or calcitriol 0.25 μg daily. The primary efficacy end point of the base study was percent change from baseline in lumbar spine BMD (month 6). Hypercalcemia and hypercalciuria were safety events of special interest. RESULTS A total of 219 patients (ALN/D5600 n = 111, calcitriol n = 108) were randomized. Baseline characteristics were similar, 30.3 % baseline 25-hydroxyvitamin D (25(OH)D) ≤15 ng/mL. At months 6 and 12, changes in lumbar spine BMD from baseline were 3.5 versus 1.6 % and 5.2 versus 2.3 % for ALN/D5600 versus calcitriol (between-group differences p < 0.001), respectively. Between-group differences for ALN/D5600 versus calcitriol were significant (p < 0.001) at months 6 and 12 for change from baseline in procollagen type 1 N-terminal propeptide (-59.1 versus -16.8 %, -68.1 versus -17.0 %) and serum C-telopeptides (-79.2 versus -27.2 %, -76.2 versus -24.2 %). Drug-related adverse events (AEs) and discontinuations due to drug-related AEs occurred in 15 (14.0 %) versus 8 (7.4 %) patients and 3 (2.8 %) versus 0 patients in the ALN/D5600 and calcitriol group, respectively. Hypercalciuria 12-month incidence (24-h urine Ca >300 mg) was 8.4 (ALN/D5600) versus 13.9 % (calcitriol) (p > 0.05). One patient (calcitriol) had hypercalcemia. CONCLUSIONS ALN/D5600 produced greater increases in lumbar spine BMD and greater decreases in bone turnover markers versus calcitriol in osteoporotic Chinese women. It is not known whether the greater increase in BMD results in fewer fractures. ALN/D5600 was generally well tolerated in Chinese patients.

Abstract
In this work, we investigate the plasmon-induced optical and magneto-optical anisotropies in the large-area square-ordered Co antidots film. It shows that both the outline of reflectivity spectrum and Kerr spectrum are significantly modified by surface plasmon polarition (SPP) resonances. Moreover, the magnitude of Kerr angle reaches to about 10 minutes at the azimuthal angle 45°, which is over 3 times of that of pure Co film. These phenomena are attributed to the SPP resonances with different diffraction orders of reciprocal lattice vectors.

Abstract
OBJECTIVE To study the normal reference value of adult tibial speed of sound (tibia SOS) in Beijing region. METHODS 951 normal volunteers (male/female = 461/490) were included in this study. Speed of sound were measured in the middle of tibia by ultrasound scan (Sound Scan 2000, Myrid, Isereal). According to their gender and age, all subjects were divided into different subgroup by 10 year-age period. RESULTS The peak value of SOS presented in 30-39 years period in both male and female. The peak value was higher in males than in females. After reach the peak value, the tibial SOS begin to decline. The decreasing rate was fast in SOS were found at 50-59 period in female and over 50-59 years old in male. The tibia values of SOS of postmenopausal was obviously lower than that of premenopausal women. The relationship of menopausal duration and the values if tibial SOS was found to be a non-linear curve, which included 3 stages: the quick decrease, stabilization and further decrease. CONCLUSION The tibia values of SOS provides a kind of meaningful diagnostic criteria of osteoporosis.
