Six cases of Paget′s disease of bone, including 5 males and 1 female, aged (57. 7 ±11. 8) years old, were recruited. Mean duration of disease was (7. 5±6. 5) years. Clinical manifestations were bone pain and bone deformity. The lesions mainly reside in the pelvis and femur. X-ray film showed typical lesion of Paget′s disease of bone, such as impaired bone trabecular structure with coarseness and disorder, cortical thickening, medullary cavity narrowing and skeletal deformation. Bone scan revealed abnormal radionuclide concentration in the involved bone. Serum alkaline phosphatase ( ALP) in 6 patients was increased ( median 235 U/ L). 5 patients received zoledronic acid sodium intravenous infusion therapy. Bone pain was relieved obviously in 5 patients after treatment for 2-3 months. Physical activity was greatly improved, and serum ALP levels significantly decreased.

A 47-year-old Chinese man with hypophosphatemic osteomalacia suffered from bone pain, difficulty in walking and pseudo-fractures. Biochemical examination showed a lowered serum phosphorus level and an elevated alkaline phosphatase level. The X-ray examination showed pseudo-fractures of multiple ribs, low bone density, biconcave deformities of the lumbar vertebrae, and pseudo-fracture of the right superior ramus of the pubis. A diagnosis of hypophosphatemic osteomalacia was made. The case was treated with oral neutral phosphate solution, calcitriol and Caltrate D. After treatment for two years, biochemical indicators were improved, and pseudo-fractures healed. Clinically, hypophosphatemic osteomalacia is often overlooked or misdiagnosed. In addition, the duration and dosage of these drugs should be appropriate, in order to avoid tertiary hyperparathyroidism or poor response to treatment.

Objective:To investigate relationship between parents'marital relationship and intergenerational transmission of value orientation of marriage and love among college students.Methods:Totally 712 families inclu-ding a college student and his/her parents from 9 universities were surveyed.The Marital Health Test (MHT)was used to assess parents'marital relationship and transmission of value orientation of marriage and love from father and mother.The structural equation modeling and stepwise multiple regression were used to analysis the relationship between parents'marital relationship and intergenerational transmission of value orientation of marriage and love a-mong college students.Results:Moderate correlations (r =0.24 -0.58,Ps <0.01 )were found between parents'marital relationship and transmission of value orientation of marriage and love from father and mother.Path analysis suggested that paths from parents'marital relationship to paternal transmission and maternal transmission were statis-tically significant (path coefficient was 0.59 and 0.75).Grouping regression analysis showed that the influences of parents 'marital relationship of same-sex transmission (R2 =0.49,0.35 ) were greater than opposite-sex transmission.Conclusions:The findings indicate that parents'marital relationship could facilitate the intergeneration-al transmission of value orientation of marriage and love.Moreover,the influences of parents'marital relationship of same-gender transmission may be greater than opposite-sex transmission.

Objective:To investigate the normal reference values of spinal bone mineral density measured by quantitative computed tomography (QCT) and the differences of bone mineral density (BMD) in different regions of in Chinese adult males.Methods:Men who underwent low-dose CT lung scan for cancer screening in regions of Northeast, North, East, South, Central and Southwest of China from January 2018 to December 2019 were selected. And the lumbar vertebrae BMD values in the male subjects were measured by the QCT system (Mindways Software, Inc.). The mean BMD values and their decline rates were calculated at an age interval of 10 years, and the prevalence of osteoporosis was calculated according to the American College of Radiology spine QCT osteoporosis diagnostic criteria.Results:A total of 50 682 males with a mean age of (50.22±12.79) years (ranged 20 to 98 years) were included in this study. The peak BMD of (173.11±28.56) mg/cm 3 in the healthy Chinese adult male population appeared in the age group of 20 to 29 years and then declined with age. Before the age of 70 years, the BMD was relatively higher in males in South China, and it was lower in Central China and Southwest China, and it was intermediate in Northeast, North and East of China, with statistically significant differences. There was no significant differences in BMD in the males in the two age groups of 70 to 79 years and 80 and older among the regions in China. The overall decline rate of spinal BMD in Chinese males under QCT was about 46.92% over the lifetime, and it declined obviouslyin the 40-49 age group. The overall prevalence of osteoporosis in Chinese male population aged 50 years and above was approximately 11.42%, with the highest prevalence in Southwest China and Central China (14.72% and 13.87%, respectively) and the lowest in North China and South China (8.53% and 7.71%, respectively). Conclusions:A reference of lumbar spine BMD values for healthy males in China based on QCT is established. BMD values were highest in South China and Lowest in Central China.
