The present study aimed to investigate the effect of various adjuvant rice on the quality of rice-steamed Rehmanniae Radix(RSRR) with Japonica rice, millet, yellow rice, black rice, and glutinous rice as raw materials, and analyze the anti-osteoporosis effect of RSRR by the optimal adjuvant rice. On the basis of the established UPLC-MS/MS method for the determination of the content of catalpol and rehmannioside D, comprehensive weighted scoring method was employed to evaluate the effect of various auxiliary rice on the quality of RSRR with the content of catalpol and rehmannioside D, character score, and taste score as indicators to optimize adjuvant rice. The osteoporosis model was induced by ovariectomy in rats. SD rats were randomly divided into a sham operation group, a model group, a positive control group, and low-dose and high-dose groups of Rehmanniae Radix, RSRR, steamed Rehmanniae Radix, and Epimedii Folium-RSRR. After treatment for 12 weeks, body weight, bone calcium content, and bone mineral density were mea-sured. The results showed that Japonica rice was selected as the optimal adjuvant due to the highest comprehensive score of RSRR steamed by Japonica rice. Rehmanniae Radix, RSRR, steamed Rehmanniae Radix, as well as Epimedii Folium-RSRR, could improve osteoporosis by increasing bone calcium content and bone mineral density. RSRR was superior to Rehmanniae Radix in improving osteo-porosis. However, there was no significant difference between RSRR and steamed Rehmanniae Radix. This study confirmed that Japo-nica rice was the optimal adjuvant rice of RSRR and verified the anti-osteoporosis effect of RSRR, which laid a foundation for further research on the pharmacological action and mechanism of RSRR.

This study aims to provide evidence for clinical practice by systematically reviewing the efficacy and safety of Gusongbao preparation in the treatment of primary osteoporosis(POP). The relevant papers were retrieved from four Chinese academic journal databases and four English academic journal databases(from inception to May 31, 2022). The randomized controlled trial(RCT) of Gusongbao preparation in the treatment of POP was included after screening according to the inclusion and exclusion criteria. The quality of articles was evaluated using risk assessment tools, and the extracted data were subjected to Meta-analysis in RevMan 5.3. A total of 657 articles were retrieved, in which 15 articles were included in this study, which involved 16 RCTs. A total of 3 292 patients(1 071 in the observation group and 2 221 in the control group) were included in this study. In the treatment of POP, Gusongbao preparation+conventional treatment was superior to conventional treatment alone in terms of increasing lumbar spine(L2-L4) bone mineral density(MD=0.03, 95%CI[0.02, 0.04], P<0.000 01) and femoral neck bone mineral density, reducing low back pain(MD=-1.69, 95%CI[-2.46,-0.92], P<0.000 1) and improving clinical efficacy(RR=1.36, 95%CI[1.21, 1.53], P<0.000 01). Gusongbao preparation was comparable to similar Chinese patent medicines in terms of improving clinical efficacy(RR=0.95, 95%CI[0.86, 1.04], P=0.23). Gusongbao preparation was inferior to similar Chinese patent medicines in reducing traditional Chinese medicine syndrome scores(MD=1.08, 95%CI[0.44, 1.71], P=0.000 9) and improving Chinese medicine syndrome efficacy(RR=0.89, 95%CI[0.83, 0.95], P=0.000 4). The incidence of adverse reactions of Gusongbao preparation alone or combined with conventio-nal treatment was comparable to that of similar Chinese patent medicines(RR=0.98, 95%CI[0.57, 1.69], P=0.94) or conventio-nal treatment(RR=0.73, 95%CI[0.38, 1.42], P=0.35), and the adverse reactions were mainly gastrointestinal discomforts. According to the available data, Gusongbao preparation combined with conventional treatment is more effective than conventional treatment alone in increasing lumbar spine(L2-L4) bone mineral density and femoral neck bone mineral density, reducing low back pain, and improving clinical efficacy. The adverse reactions of Gusongbao preparation were mainly gastrointestinal discomforts, which were mild.

Postmenopausal osteoporosis is a kind of degenerative disease, also described as "invisible killer." Estrogen is generally considered as the key hormone for women to maintain bone mineral content during their lives. Iron accumulation refers to a state of human serum ferritin that is higher than the normal value but less than 1000 μg/L. It has been found that iron accumulation and osteoporosis could occur simultaneously with the decrease in estrogen level after menopause. In recent years, many studies indicated that iron accumulation plays a vital role in postmenopausal osteoporosis, and a significant correlation has been found between iron accumulation and fragility fractures. In this review, we summarize and analyze the relevant literature including randomized controlled trials, systematic reviews, and meta-analyses between January 1996 and July 2022. We investigate the mechanism of the effect of iron accumulation on bone metabolism and discuss the relationship of iron accumulation, osteoporosis, and postmenopausal fragility fractures, as well as the main clinical treatment strategies. We conclude that it is necessary to pay attention to the phenomenon of iron accumulation in postmenopausal women with osteoporosis and explore the in-depth mechanism of abnormal bone metabolism caused by iron accumulation, in order to facilitate the discovery of effective therapeutic targets for postmenopausal osteoporosis.

INTRODUCTION: A significant treatment gap has been observed in patients with osteoporosis. Our previous audit found a 31.5% rate of anti-osteoporosis medication initiation after fragility fractures at one year. We piloted the use of telecarers to monitor osteoporosis treatment and compliance. METHODS: From January 2017 to January 2018, all hip fracture patients at Changi General Hospital, Singapore, were automatically enrolled into the Health Management Unit valued care hip fracture programme. Telecarer calls were scheduled at discharge, 3, 6 and 12 months. We assessed the acceptability, completion and treatment rates of patients enrolled in this programme. RESULTS: A total of 537 patients with a hip fracture were enrolled in the telecarer programme over one year. Their average age was 79.8 ± 8.23 years, and 63.1% of them were female. A total of 341 patients completed 12 months of follow-up, of which 251 (73.6%) patients were on treatment at 12 months. The most common cause of lack of initiation of secondary osteoporosis treatment was patient or family rejection (34.4%), followed by physician failure to prescribe (24.4%) and renal impairment (24.4%). 16.7% of patients were deemed to have advanced dementia with a life-limiting illness and were, thus, deemed unsuitable for treatment. CONCLUSION Telecarers may be a useful adjunct in the monitoring of osteoporosis treatment after hip fractures in an elderly population. The main limitations are patient or family rejection and physician inertia. Further studies should focus on a combination of interventions for both patients and physicians to increase awareness of secondary fracture prevention.

Glucocorticoid-induced osteoporosis (GIOP) is a skeletal disease characterized by decreased bone strength and increased fracture risk associated with long-term glucocorticoid use. GIOP is the most common secondary osteoporosis that critically affects the quality of life of patients. Currently, the incidence of GIOP in China remains high, with insufficient awareness and lack of prevention and treatment norms. Therefore, the Chinese Rheumatology Association has established this standard based on domestic and international experience, with the aim of raising awareness of prevention and treatment among clinicians, guiding the standardized diagnosis and treatment of this disease, and improving the overall prognosis of patients with GIOP.

OBJECTIVE: To compare the therapeutic effect on postmenopausal osteoporosis (PMOP) between Lingnan Chen's needling technique and calcitriol soft capsules and investigate the effect mechanism in view of serum growth hormone (GH) and insulin-like growth factor-1 (IGF-1). METHODS: Seventy patients of PMOP were randomized into an observation group (35 cases, 4 cases dropped off ) and a control group (35 cases, 3 cases dropped off ). The patients of both groups were treated with calcium carbonate D3 tablets orally (600 mg each time, once daily). In the observation group, acupuncture was delivered at Shenshu (BL 23), Pishu (BL 20), Guanyuan (CV 4), Sanyinjiao (SP 6), etc. with the specific reinforcing-reducing technique and qi-conducting technique of Lingnan Chen's acupuncture, once every two days, three times a week. In the control group, calcitriol soft capsules were taken orally, 0.25 μg each time, twice a day. The intervention measures of two groups all lasted 12 weeks. Before and after treatment, the bone mineral density (BMD), the levels of serum GH and IGF-1 were assessed in two groups. Before treatment and 4, 8 and 12 weeks after treatment, TCM symptoms score and the MOS item short form health survey (SF-36) score were evaluated and the therapeutic effects were compared between groups. RESULTS: In both within-group and between-group comparisons, the difference in BMD was not significant before and after treatment (P>0.05). After treatment, the levels of serum GH and IGF-1 were increased in the observation group (P<0.05), and higher than the control group (P<0.05). After 4, 8 and 12 weeks of treatment, the scores of TCM symptoms were reduced in both groups compared with those before treatment (P<0.05), and the score in the observation group was lower than that in the control group (P<0.05). After 4, 8 and 12 weeks of treatment, except the score of general health 4 weeks after treatment in the control group, the scores of the other domains in SF-36 were increased in both groups compared with those before treatment (P<0.05). After 12 weeks of treatment, except the score for the general health and social functions, the scores of the other domains of SF-36 in the observation group were all higher than those in the control group (P<0.05). The total effective rate was 83.9% (26/31) in the observation group, higher than 59.4% (19/32) in the control group (P<0.05). CONCLUSION Lingnan Chen's needling technique is effective on postmenopausal osteoporosis. This therapy may relieve the symptoms of osteoporosis and improve the quality of life, better than calcitriol soft capsules, and the effect mechanism may be related to the up-regulation of serum GH and IGF-1 in the patients.

OBJECTIVE: To observe the effect of electroacupuncture on motor function and muscle state in patients with primary osteoporosis (POP). METHODS: A total of 60 female patients with POP were randomized into an observation group (30 cases, 1 case dropped off) and a control group (30 cases, 1 case dropped off). On the basis of adjusting lifestyle, caltrate was given orally in the control group, 2 pills a day for 4 weeks. On the basis of the treatment in the control group, electroacupuncture was applied at Zusanli (ST 36), Yanglingquan (GB 34), Ganshu (BL 18), Pishu (BL 20), Shenshu (BL 23), etc. in the observation group, with disperse-dense wave of 2 Hz/10 Hz in frequency, once every other day, 3 times a week for 4 weeks. The time of timed up-and-go test (TUGT) and the value of 10 m maximal walking speed (10 m MWS) before and after treatment were compared in the two groups, and the Young's modulus values of bilateral multifidus muscles in prone position and sitting position before and after treatment were compared by real-time shear wave elastography (SWE) in the two groups. RESULTS: After treatment, the TUGT time was decreased compared before treatment in the observation group (P<0.01), and that in the observation group was shorter than the control group (P<0.01). After treatment, the value of 10 m MWS test was increased compared before treatment in the observation group (P<0.05). After treatment, the Young's modulus values of bilateral multifidus muscles in prone position and sitting position were increased compared before treatment in the observation group (P<0.01); except for the left side in sitting position, the Young's modulus values of multifidus muscles in the observation group were higher than those in the control group (P<0.01, P<0.05). CONCLUSION On the basis of oral caltrate, electroacupuncture can improve the motor function and muscle state in patients with POP.

With the rise of incidence, fatality rate, and number of young cases, diabetes mellitus has been one of the seven major diseases threatening human health. Although many antidiabetic drugs(oral or for injection) are available, the majority have serious side effects during the long-term use. Thus, it is of particularly vital to develop new drugs with low risk and definite effect. Psoraleae Fructus, a traditional medicinal widely used in the folk, has hypoglycemic, anti-osteoporosis, antitumor, estrogen-like, and anti-inflammatory effects. Thus, it has great clinical application potential. Chinese medicine and the active ingredients, characterized by multiple targets, multiple pathways, and multiple effects in the treatment of diabetes mellitus, have distinct advantages in clinical application. However, the safety of Chinese medicine remains to be a challenge, and one of keys is to clarifying the mechanism of a single Chinese medicinal and its active ingredients. With the method of literature research, this study summarized and analyzed the hypoglycemic mechanisms of Psoraleae Fructus and its main active ingredients over the last decade: regulating glucose metabolism, improving insulin resistance, and directly acting on pancreatic β-cells. The result is expected to serve as a reference for further research on the effects of Psoraleae Fructus and its main chemical constituents in lowering blood glucose and preventing diabetes mellitus and the clinical application.

OBJECTIVE: To explore the mechanism of proteasome inhibitor MG132 in improving osteoporosis. METHODS: Total of 32 female SD rats, weighing 220 to 250 g and 8 weeks old, were selected. They were randomly divided into 4 groups(n=8). Rats of group A and group B were cut off ovaris on both sides to make model of osteoporosis, and then they were given proteasome inhibitors MG132 and dimethyl sufoxide (DMSO) respectively. Group C was a sham group and rats were given MG132. Group D was a normal group and rats were given MG132 too. The rats were killed in batches at 6 and 12 weeks after administration, and the femoral neck tissues were obtained. Relevant data were analyzed, such as pathomorphological observation, micro-CT analysis, detection of 20S proteasome activity in tissues, and expression of Wnt and β-catenin. RESULTS: Morphological observation showed that the trabecular were slightly thinner, reticulated, and occasionally interrupted in group A, while the trabecular were obviously thinner and discontinuous in group B. And the trabecular were intact and arranged reticulated in group C and D. The analysis results of bone mineral density(BMD), bone surface(BS), bone volume/total volume(BV/TV) and trabecular thickness(Tb.Th) showed that group B was worse than other groups in all parameters at different time points(P<0.05), and group A was worse than group C and group D in BS(P<0.05), there was no significant difference in all parameters between group C and group D. RFU value of 20S proteasome in group B was significantly higher than that in other groups(P<0.05). According to the results of Western blot, the gray values of Wnt protein and β-catenin protein in group A were significantly higher than those in other groups (P<0.05). CONCLUSION MG-132, a ubiquitin proteasome inhibitor, can regulate Wnt/β-catenin signaling pathway by inhibiting the degradation of β-catenin protein, and delaying the occurrence and development of osteoporosis.

The editorial group of the clinical practice guideline for postmenopausal osteoporosis(PMOP) with traditional Chinese medicine(TCM)(hereinafter referred to as "guideline") is composed of experts specialized in TCM orthopedics, TCM gynecology, clinical epidemiology, etc. The guideline was formulated through registration, collection and selection of clinical issues/outcome indicators, evidence retrieval and screening, preparation of systematic reviews, evaluation of evidence quality, formation of recommendations, drafting, and peer review. The syndromes and treatment of PMOP are elaborated in detail. Specifically, Liuwei Dihuang Pills and Zuogui Pills are recommended for PMOP with Yin deficiency in the liver and kidney, Qing'e Pills for PMOP with kidney deficiency and blood stasis, Yougui Pills and Jingui Shenqi Pills for PMOP with Yang deficiency in the spleen and kidney, and Er'xian Decoction for PMOP with Yin and Yang deficiency in the kidney. In addition, Duhuo Jisheng Decoction can be used to relieve pain. The commonly used Chinese patent medicines include Xianling Gubao Capsules, Qianggu Capsules, Jintiange Capsules, Gushukang Capsules, Hugu Capsules, Jinwu Gutong Capsules, and Guyuling Capsules. Acupuncture and moxibustion are also effective approaches for PMOP. The rehabilitation and daily management were carried out by exercise therapies such as Baduanjin(eight-section brocade), Wuqinxi(five-animal exercises), and Taijiquan(Tai Chi), Chinese medicine diet, health education, and fall prevention. The promotion and application of this guideline will facilitate the implementation of TCM prevention and treatment of PMOP, ensure the quality of life of PMOP patients, provide effective and safe TCM treatment measures for PMOP, and reduce the risk of fracture complications.
