Helicobacter pylori (HP) is an infectious pathogen which can easily infringe gastric mucosa. If the body is infected by HP, it can release cytokines, such as TNF-alpha, IL-1 and IL-6. These cytokines can regulate the absorption and transformation of bone, promote the formation of osteoclast, and then cause localized or systemic osteoporosis. HP infection may decrease the level of estrogen and vitamin B12, which is considered as a risk factor for osteoporosis. Helicobacter pylori infection is related with the occurrence of gastritis, peptic ulcer and gastric malignancies, and these diseases and treatments are associated with osteoporosis. Meanwhile the application of proton pump inhibitor (PPI) can influence absorption of calcium, decrease the level of serum calcium and increase the risk of fracture. Gastrostomy may cause bone metabolism disorders.

Degenerative scoliosis is one of the important reasons of low back pain in middle-aged and elderly. The surgical treatment has been gradually paid more attention to in recent years. Pain and the quality of life are the key points of the surgical treatment. In addition to neurogenic compression,clinical symptoms and health-related quality of life are also closely related to the three-dimensional deformity of spine. Researchers try to employ different classifications of degenerative scoliosis to guide personalizedly surgical treatment. In the future,osteoporosis and complications may be the research highlights in the surgical treatment of degenerative scoliosis.

To explore the theory of "Shaoyang Meridians being in charge of the bone" in Huangdi's Internal Classic, which has been buried for long time. With citation of Huangdi's Internal Classic and exposition of famous experts, speculate on the contents and meanings systematically. Results indicate that the theory of "Shaoyang Meridians being in charge of the bone" possibly first in the world recognizes osteoporosis being a general bony disease, and articulates that the Foot-Shaoyang Meradians can modulate bony strength under physiological and pathological conditions, and treat osteoporosis which mainly manifests as ostealgia and easy fracture.

Objective: To understand the prevalence of osteoporosis and related factors in postmenopausal women aged ≥40 years in China and provide scientific evidence for osteoporosis prevention and control. Methods: Data of this study were from the 2018 China Osteoporosis Epidemiological Survey, covering 44 counties (districts) in 11 provinces in China. Related variables were collected by questionnaire survey and physical measurement, and the BMD of lumbar spine and proximal femur was measured by dual-energy X-ray absorption method. The prevalence of osteoporosis and its 95%CI in postmenopausal women aged ≥40 years were estimated with complex sampling weights. Results: A total of 5 728 postmenopausal women aged ≥40 years were included in the analysis and the prevalence of osteoporosis was 32.5% (95%CI: 30.3%-34.7%). The prevalence of osteoporosis in postmenopausal women aged 40-49 years, 50-59 years, 60-69 years, 70-79 years, and ≥80 years were 16.0% (95%CI:4.5%-27.5%), 18.4% (95%CI:15.9%-20.8%), 37.5% (95%CI:34.5%-40.4%), 52.9% (95%CI: 47.5%-58.3%), and 68.0% (95%CI:55.9%-80.1%) respectively. The prevalence of osteoporosis was higher (P<0.001) in those with education level of primary school or below (47.2%, 95%CI: 43.0%-51.3%) and in those with individual annual income less than 10 000 Yuan, (40.3%, 95%CI: 36.9%-43.7%). The prevalence of osteoporosis was 35.1% in rural areas (95%CI: 32.0%-38.1%), which was higher than that in urban areas (P<0.001). The prevalence of osteoporosis in low weight, normal weight, overweight and obese groups were 69.9% (95%CI: 59.0%-80.8%), 42.2% (95%CI: 38.7%-45.7%), 24.2% (95%CI: 21.3%-27.1%) and 14.6% (95%CI: 11.1%-18.0%), respectively. The prevalence of osteoporosis in those with menstrual maintenance years ≤30 years and in those with menopause years ≥11 years were 46.1% (95%CI:40.8%-51.3%) and 48.2% (95%CI:45.0%-51.3%), respectively. Multivariate logistic analysis showed that age ≥60 years, education level of primary school or below, annual household income per capita less than 10 000 Yuan, low body weight, menstrual maintenance years ≤30 years, menopause years ≥11 years were risk factors of osteoporosis in postmenopausal women in China. Conclusions: The prevalence of osteoporosis was high in postmenopausal women aged ≥40 years in China, and there were differences in osteoporosis prevalence among different socioeconomic groups. Effective interventions should be taken for the prevention and control of osteoporosis in key groups in the future.

To compare the bone mineral density (BMD) and determine the frequency of osteoporosis in mild and advanced ankylosing spondylitis (AS) cases. Seventy three patients with AS were enrolled in this study. The BMD was analyzed at the lumbar spine and hip by dual energy X-ray absorptiometry. The patients were diagnosed as being "normal, osteopenia, or osteoporosis" according to the WHO classification. Using the BASRI-lumbar and BASRI-hip scores, the patients were grouped in mild and advanced AS categories. The mean BMD in the lumbar spine and hip of patients with mild and advanced AS was similar (p > 0.05). While 61.6% of the patients were found to have osteopenia or osteoporosis in the lumbar spine, 46.6% had osteopenia or osteoporosis in the total hip. Of the patients with advanced AS 54.3% had osteopenia or osteoporosis in the lumbar spine, 75% in the total hip. Of the patients with mild AS patients had 68.4% osteopenia or osteoporosis in the lumbar spine, and 42.3% in the total hip. The osteopenia or osteoporosis frequency of the mild and advanced cases of AS in the lumbar spine was similar (p > 0.05). In the advanced AS patients, osteopenia or osteoporosis frequency was significantly higher in the total hip than in the mild AS patients (p < 0.05). In conclusion, there was evidence of osteoporosis in both the advanced AS and mild AS patients. The reason why the anteroposterior lumbar DXA results in the advanced AS patients were similar to the mild ones may be due to the existence of syndesmophytes and ligament calcification. In these cases, it is more convenient to use a hip DXA for assessing the extent of osteoporosis.

OBJECTIVETo observe general conditions, physiological condition, viscera wet weight and kidney asthenia serological index in osteoporosis model rats established by bilateral ovarian resection, and provide basis for treating osteoporosis by invigorating kidney.

METHODSTwenty-four female SD rats were randomly divided into 3 groups as model group, sham group and normal group. After anesthesia,model group were treated by bilateral ovarian resection, sham group by sham operation, and normal group without any processing. Pathological tissue and bone mineral density (BMD) of femur was performed 3 months postoperatively. The general conditions and physiological conditions were processed after successfully modeling. Electronic balance was used to collect the weight of kidney, drenal, pituitary, and uterus. Estrogen (E2), Adrenocorticotropic hormone (ACTH), Three typical thyroid original acid (T3), Four typical thyroid original acid (T4) were detected by ELISA.

RESULTSOsteoporosis model appeared with syndromes of kidney deficiency, such as body hair without burnish, chills, cluster, sluggishness, eyes dark, eye movement slow, slow to respond to the delay, decreased appetite, activities slow, body fat, and drowsiness, defecate slightly thin andclear abundant urine. Mobility, anal temperature and food-intake were lower than normal and sham group; the level of ACTH, E2, T3, T4 lower than sham and normal group; the weight of kidney, drenal, pituitary, and uterus also lower than other two groups.

CONCLUSIONOsteoporotic model rats, established by bilateral ovarian resection, have manifestation of organic and functional performance of kidney deficiency. Therefore, osteoporotic model rats have the pathogenesis of kidney asthenia and clinical manifestations of kidney deficiency.

OBJECTIVETo investigate the therapeutic effect of recombinant human parathyroid hormone(1-34) [rhPTH(1-34)] on osteoporosis of ovariectomized rats.

METHODSThe model of osteoporosis was formed after 3 months of ovariectomy with 6-month age of 80 rats. Another 20 rats was control of sham operation. rhPTH(1-34) was subcutaneously injected once daily with 5, 10, 20, 40 micrograms/kg for 3 months. There were 10 rats in each group. The control of therapy included Salmon Calcitonin to 10 rats and Alendronate sodium to 10 rats. The bone weight of dry and ash, bone mineral density, bone biomechanical property, trabecular area, bone mineral deposition and serum alkaline phosphatase, Ca, P and urinary Pyridinoline/creatin (Pyd/Cr) were measured after the end of therapy.

RESULTSWhen administered to animals as a single subcutaneous injection once daily, rhPTH(1-34) increased obviously bone mass, bone biomechanical property and trabecular area, as well as bone deposition compared with the animals of control group. The bone architecture was ultimately improved by rhPTH(1-34) therapy.

CONCLUSIONSRats of ovariectomized-induced osteoporosis possess obvious effect of treatment with low dose of rhPTH(1-34) administered once daily.

Osteoporosis is charactered by body bone mass reduce and bone microstructure degration. With the improvement of biology-psychology-social medical model, it have found a certain relation between osteoporosis and psychology. Psychology have an influence on BMD, contents of bone transition index, bone cytokine consistency and fragility fracture rate. Meantime, life of quality of the patients have been affected by osteoporosis, leading to their psychology situation have an according changes.
