Effect of Osteoking on Inflammatory Injury and NF-κB/NFATc1 Signaling Pathway in Model Mice with Postmenopausal Osteoporosis / 中国实验方剂学杂志

ObjectiveTo explore the possible mechanism of Osteoking （OK） on postmenopausal osteoporosis （PMOP）. MethodForty adult female mice were randomly divided into a sham operation （Sham） group， osteoporosis model （OVX） group， estradiol intervention （E2） group， and OK group， with 10 mice in each group. The modeling was completed by conventional back double incision ovariectomy， and the corresponding drugs were given one week later. After 12 weeks， the body mass and uterine index of mice were measured， and the pathological changes of bone tissue and the number of osteoclasts （OCs） were determined by hematoxylin-eosin （HE） and tartrate-resistant acid phosphatase （TRAP） staining， respectively. Bone mineral density （BMD）， trabecular number （Tb.N）， trabecular separation （Tb.Sp）， and bone volume fraction （BV/TV） were measured by microcomputed tomography （Micro-CT）. The maximum load of the femur was detected by a three-point bending test. The contents of tumor necrosis factor-α （TNF-α） and bone resorption marker C-terminal telopeptide of type Ⅰ collagen （CTX-1） were measured by enzyme linked immunosorbent assay （ELISA）. The protein expression levels of nuclear factor-kappa B p65 （NF-κB p65）， phosphorylated nuclear factor-kappa B p65 （p-NF-κB p65）， nuclear factor kappa B inhibitor alpha （IκBα）， phosphorylated nuclear factor kappa B alpha （p-IκBα）， nuclear factor of activated T cells 1 （NFATc1）， and proto-oncogene （c-Fos） were detected by Western blot. The mRNA expressions of OCs-related specific genes matrix metalloproteinase-9 （MMP-9）， NFATc1， TRAP， cathepsin K （CTSK）， and c-Fos were detected by real-time fluorescence quantitative polymerase chain reaction （Real-time PCR）. ResultCompared with the Sham group， the uterine index decreased significantly in the OVX group， and the body mass （BMI） increased significantly. The structure of bone trabeculae was completely damaged， and the number of OCs increased. BMD， Tb.N， BV/TV， and maximum load decreased， while Tb.Sp was up-regulated. The levels of TNF-α and CTX-1 in serum were up-regulated. The protein expressions of c-Fos， p-NF-κB p65/NF-κB p65， NFATc1， and p-IκBα/IκBα were increased. The mRNA expressions of NFATc1， c-Fos， CTSK， TRAP， and MMP-9 were up-regulated （P<0.05， P<0.01）. Compared with the OVX group， the body mass of the OK and E2 groups decreased， and the uterine index increased. The bone trabeculae increased， and the number of OCs decreased. BMD， Tb.N， BV/TV， and maximum load increased， while Tb.Sp decreased. The levels of TNF-α and CTX-1 in serum were decreased. The protein expressions of c-Fos， p-NF-κB p65/NF-κB p65， NFATc1， and p-IκBα/IκBα were decreased， and the mRNA expressions of NFATc1， c-Fos， CTSK， TRAP， and MMP-9 were decreased （P<0.05， P<0.01）. ConclusionOK can inhibit the NF-κB/NFATc1 signaling pathway and reduce bone mass loss by reducing the level of inflammatory injury factors in PMOP mice， which is one of the mechanisms for treating PMOP.

Resumen Durante la menopausia se producen cambios metabólicos que favorecen la ganancia de peso y la obesidad abdominal, lo cual facilita el desarrollo de dislipidemias y aumenta el riesgo cardiovascular. El propósito del estudio fue comparar el perfil lipídico y los índices de riesgo cardiometabólico (IRCM) entre mujeres posmenopáusicas del Municipio Naguanagua, Estado Carabobo, Venezuela, clasificadas de acuerdo con su grado de adiposidad. El estudio fue de corte transversal, descriptivo, en el cual participaron 205 mujeres con una mediana de edad de 56 años. Se evaluaron indicadores de adiposidad: índice de masa corporal (IMC), porcentaje de grasa corporal (PGC), circunferencia de cintura (CC), e índice cintura/talla (ICT); así como el perfil lipídico y los IRCM. Se encontraron altos porcentajes de exceso de peso (80%), exceso de grasa corporal (92%), obesidad abdominal (61%) y riesgo metabólico de acuerdo con el ICT (69%). Las mujeres con obesidad mostraron los valores más bajos de cHDL, y aquellas con grasa muy alta, obesidad abdominal y riesgo metabólico de acuerdo con el ICT, los valores más elevados del índice TG/HDL. Se recomiendan otros estudios en este grupo poblacional para comprender mejor la asociación encontrada entre el grado de adiposidad y las alteraciones en el metabolismo de los lípidos con el fin de tomar acciones preventivas en estos trastornos relacionados con el síndrome metabólico.

Abstract During menopause, metabolic changes occur that promote weight gain and abdominal obesity, facilitating the development of dyslipidemias and increasing cardiovascular risk. The purpose of the study was to compare the lipid profile and the cardiometabolic risk indexes (IRCM) among postmenopausal women from the Naguanagua Municipality, Carabobo State, Venezuela, classified according to their degree of adiposity. It was a cross-sectional, descriptive study in which 205 women with a median age of 56 years participated. Adiposity indicators were evaluated: body mass index (BMI), percentage of body fat (PBF), waist circumference (WC), and waist-to-height ratio (WHtR); as well as the lipid profile and the IRCM. High percentages of excess weight (80%), excess body fat (92%), abdominal obesity (61%) and metabolic risk according to the WHtR (69%) were found. Women with obesity showed the lowest values of HDL-C, and those with very high fat, abdominal obesity, and metabolic risk according to the WHtR, the highest values of the TG/HDL index. Other studies are recommended on this population group to better understand the association found between the degree of adiposity and alterations in lipid metabolism to take preventive actions in these disorders related to the metabolic syndrome.

A CROSS-SECTIONAL STUDY TO DETERMINE STRESS LEVEL AMONG POSTMENOPAUSAL WOMEN IN RURAL AREA OF BHAGALPUR (BIHAR)

Background: Menopause is a natural reproductive period that affects women's lives between the ages of 45 and 55 due to various physical and mental changes. It usually happens when a lady is in her late 40s to early 50s (Barkha D et al., 2018). Many women see the menopausal transition as distressing (The North American Menopause Society, 2016). Menopausal women in rural locations may experience higher physical, psychological, and social stress. They also have more medical issues and worse self-esteem than males. The objective of present is to measure the stress experienced by pos Objective: tmenopausal women living in rural areas of the Bhagalpur district of Bihar. A cross-sectional survey method is used to measure stre Method: ss level of postmenopausal women. total 100 postmenopausal women were selected using simple random sampling within the age range of 45-55 years. The level of stress was measured by using a structured self-administered schedule. The result of this study revealed that most pos Result: tmenopausal women (70%) reported severe stress levels, 28% had moderate stress levels, whereas only 2% reported low-stress levels. Alt Conclusion: hough this is a short study but it offers a beginning for the future mapping of stress levels on menopause timing. Researchers looking into the stress experienced by postmenopausal women can also use this knowledge.

Postmenopausal Experiences and Constraints in Seeking Health Care in A Rural Area of West Bengal, India

Introduction: During menopause, women experience various psychological or physical changes which need adequate attention. Moreover, women don’t seek help for these problems due to their hesitancy, lack of awareness, socio-cultural, financial constraints or as they feel this is a natural-phenomenon. The study aims to explore the postmenopausal experiences faced by women during menopause and to elicit the constraints faced by them in seeking health-care services. Methodology: This was a qualitative study with phenomenological approach conducted among post-menopausal women (≥45 years) from Oct 2022-Jan 2023 with the help of In-Depth-Interview guide in four villages of Bhatar Block, Purba-Bardhaman District. Considering the availability of the study participants, they were selected purposively from the list prepared by ASHA of each village and recruitment done till the point of data-saturation. Inductive thematic-analysis was used to identify codes and themes. Results: During menopause, women experienced physical and psychological changes in the body, changes in social life and for these changes they had to adjust to cope-up. They felt various needs like empathy from hus-bands, children, peers. On the other hand, they did not seek help from health-care services due to their knowledge gap, dissatisfaction from previous-visit, cost-issue and unavailability of resources in health-care delivery system. Conclusion: Majority of the post-menopausal women faced various problems associated with menopause, but very few had sought help. So, health care providers have an important role to generate awareness among post-menopausal women regarding physical and mental changes during this phase.

A cross-sectional comparative study of some cardiovascular risk factors in premenopausal and postmenopausal apparently healthy women of Ranchi

Background: Loss of estrogenic support may put postmenopausal women at higher risk of cardiovascular diseases. Aims and Objectives: This study aimed to examine premenopausal and postmenopausal woman to provide pertinent data on some of the cardiovascular risk factors and to know approximately the period which is under protection of estrogen and the period from which a woman is affected by changes in cardiovascular risk factors. Materials and Methods: This cross-sectional study was conducted in RIMS Ranchi from February 2018 to August 2019. A total of 262 apparently healthy women in the age group of 35–60 years were assessed for cardiovascular risk factors. Parameters assessed in premenopausal and postmenopausal women were heart rate, blood pressure (Systolic and Diastolic Blood Pressure), body mass index (BMI), waist circumference, hip circumference, blood sugar level, and lipid profile of the subjects. Results: Out of 262 participants, 132 were in the premenopausal group with mean age of 39.76 years and 130 were in the postmenopausal group with mean age of 50.8. Except BMI, all other cardiovascular risk parameters showed significant difference between premenopausal and postmenopausal women. Conclusion: We concluded that adverse changes in lipid profile and blood sugar along with significant increase in other cardiac risk factors in postmenopausal women as compared to premenopausal group of the study predisposed this group of women at increased risk of having cardiovascular disease in near future. Hence, preventive measures against cardiovascular disease risk should be started in premenopausal period only.

The Relationship between Bone Mineral Densitometry and Visceral Adiposity Index in Postmenopausal Women / A relação entre a densitometria mineral óssea e o índice de adiposidade visceral em mulheres na pós-menopausa

Abstract Objective It was aimed to compare visceral adiposity index (VAI) levels in patients with normal bone mineral density (BMD), osteopenia, and osteoporosis. Methods One hundred twenty postmenopausal women (40 with normal BMD, 40 with osteopenia, and 40 with osteoporosis) between the ages of 50 to 70 years were included in the study. For females, the VAI was calculated using the formula (waist circumference [WC]/[36.58 + (1.89 x body mass index (BMI))]) x (1.52/High-density lipoprotein [HDL]-cholesterol [mmol/L]) x (triglyceride [TG]/0.81 [mmol/L]). Results The time of menopause from the beginning was similar in all groups. Waist circumference was found to be higher in those with normal BMD than in the osteopenic and osteoporotic groups (p = 0.018 and p < 0.001, respectively), and it was also higher in the osteopenic group than in the osteoporotic group (p = 0.003). Height and body weight, BMI, blood pressure, insulin, glucose, HDL-cholesterol, and homeostasis model assessment-insulin resistance (HOMA-IR) levels were similar in all groups. Triglyceride levels were found to be higher in the normal BMD group, compared with the osteoporotic group (p = 0.005). The level of VAI was detected as higher in those with normal BMD, compared with the women with osteoporosis (p = 0.002). Additionally, the correlation analysis showed a positive correlation between dual-energy X-ray absorptiometry (DXA) spine T-scores, WC, VAI, and a negative correlation between DXA spine T-scores and age. Conclusion In our study, we found higher VAI levels in those with normal BMD, compared with women with osteoporosis. We consider that further studies with a larger sample size will be beneficial in elucidating the entity.

Resumo Objetivo O objetivo foi comparar os níveis de índice de adiposidade visceral (IVA) em pacientes com densidade mineral óssea (DMO) normal osteopenia e osteoporose. Métodos Cento e vinte mulheres na pós-menopausa (40 com DMO normal 40 com osteopenia e 40 com osteoporose) com idades entre 50 e 70 anos foram incluídas no estudo. Para o sexo feminino o VAI foi calculado pela fórmula (circunferência da cintura [CC]/[36 58 + (1 89 x índice de massa corporal (IMC))]) x (1 52/lipoproteína de alta densidade [HDL]-colesterol [mmol/L]) x (triglicerídeo [TG]/0 81 [mmol/L]). Resultados O tempo de menopausa desde o início foi semelhante em todos os grupos. A circunferência da cintura foi maior naqueles com DMO normal do que nos grupos osteopênicos e osteoporóticos (p = 0 018 e p < 0 001 respectivamente) e também foi maior no grupo osteopênico do que no grupo osteoporótico (p = 0 003) . Altura e peso corporal IMC pressão arterial insulina glicose HDL-colesterol e os níveis de avaliação do modelo de homeostase-resistência à insulina (HOMA-IR) foram semelhantes em todos os grupos. Os níveis de triglicerídeos foram maiores no grupo DMO normal em comparação com o grupo osteoporótico (p = 0 005). O nível de VAI foi detectado como maior naquelas com DMO normal em comparação com as mulheres com osteoporose (p = 0 002). Além disso a análise de correlação mostrou uma correlação positiva entre a absorciometria de raios-X de dupla energia (DXA) nas pontuações T da coluna CC VAI e uma correlação negativa entre as pontuações T da coluna DXA e a idade. Conclusão Em nosso estudo encontramos níveis mais elevados de VAI naquelas com DMO normal em comparação com mulheres com osteoporose. Consideramos que novos estudos com maior tamanho amostral serão benéficos na elucidação da entidade.

Dyslipidemia as a risk factor for acute myocardial infarction in postmenopausal women: An observational study

Objective: This study has evaluated risk factors, especially dyslipidemia, for an acute myocardial infarction (AMI) in postmenopausal women. Materials and Methods: This was a hospital-based, observational, single-center study among 100 postmenopausal women admitted to the medicine ward with AMI. They were categorized based on lipid profile groups, viz., dyslipidemic group and non-dyslipidemic group. All clinical parameters were studied between the groups. Results: Among anthropometric profiles, in the comparison of mean height (cm), weight (kg), body mass index (BMI) (kg/m2 ), and waist circumference (WC) (cm) for the dyslipidemic group and non-dyslipidemic group, only WC was statistically significant (P < 0.001). Most patients were hospitalized between 6 and 12 h after the onset of symptoms. At the time of hospitalization, most patients from both groups were observed to have diabetes and hypertension with poor control of postprandial blood sugar, glycated hemoglobin, and diastolic blood pressure (DBP) (P < 0.05). The dyslipidemic group’s mean C-reactive protein was higher (P < 0.05). The comparison of mean total cholesterol, triglyceride (TG), low density lipoprotein-cholesterol in mg/dL, and TG: high density lipoprotein was significantly increased (P < 0.001), while high density lipoprotein-cholesterol (mg/ dL) was significantly decreased (P < 0.001) in the dyslipidemic group. ST-segment elevation myocardial infarction is standard in both groups. The maximum patient has regional wall motion abnormality in echocardiography after day 3 of admission. Among the dyslipidemic group, ejection fraction was on the lower side, and the predominant complication was in the left ventricular failure (LVF) (P < 0.05). Conclusion: WC has a positive association with patients with AMI who have dyslipidemia and can be used as an indicator of the risk of AMI when BMI is normal. WC is a surrogate marker of abdominal fat mass (subcutaneous and intra-abdominal); increased WC is a significant component marker of metabolic syndrome and insulin resistance related to cardiovascular mortality. There was poor glycemic control and blood pressure (mainly DBP) among the dyslipidemic patients. Hypertriglyceridemia is the most common lipid abnormality, followed by hypercholesterolemia among the dyslipidemic group. LVF is the most common complication in dyslipidemic patients.

Vitamin D is associated with a low quality of life: a primary care study

Introduction: Some studies have described impairment in quality of life of vitamin-deficient subjects. However, little is known about this association in primary care. This study aimed to evaluate the association between vitamin D deficiency and quality of life in postmenopausal women attending primary care in the municipality of Santa Maria ­ Brazil. Methods: A cross-sectional study was carried out with postmenopausal women over 55 years of age, accompanied in primary care, from March to August 2014. These women were randomly selected among the participants of a cohort study in the municipality of Santa Maria ­ Brazil. Data were collected through a standardized questionnaire, quality of life was assessed using the Short Form-36 Health Survey (SF-36), and 25-hydroxyvitamin D were measured using the ALPCO® ELISA method. Results: Of the total of 78 studied women, 11.54% had vitamin D deficiency. Women with vitamin D deficiency had a poorer quality of life assessed by SF-36. In the regression analysis, both vitamin D deficiency and falls were independently associated with a lower physical component of the SF-36. Conclusion: Vitamin D deficiency is associated with poorer quality of life in the studied postmenopausal women.

Técnica modificada de colporrafia anterior por ausencia de fascia prevesical: reporte de caso / Modified technique of anterior colporraphy due to absence of prevesical fascia: case report

Resumen ANTECEDENTES: El prolapso de órganos pélvicos es frecuente en pacientes posmenopáusicas. El tratamiento definitivo, cuando el compartimiento anterior está afectado, es el quirúrgico (colporrafia anterior). Aquí se describen los desenlaces clínicos derivados de la aplicación de una técnica modificada de colporrafia anterior en una paciente con ausencia de fascia prevesical, con una estadificación POP-Q estadio II, con afectación en el compartimiento anterior. CASO CLÍNICO: Paciente de 64 años, con antecedentes de una colporrafia anterior a los 56 años, prolapso de órgano pélvico con afectación del compartimiento anterior. En el examen ginecológico se evidenció la afectación del compartimiento anterior, específicamente en el nivel II conforme a la nueva clasificación POP-Q. Debido a los antecedentes quirúrgicos se optó por la colporrafia anterior, con punto de poliglactina 910 y colpopexia por vía vaginal, con puntos de polipropileno aplicados con un dispositivo de captura de sutura para reparación de tejido nativo. El desenlace quirúrgico fue satisfactorio. CONCLUSIÓN: En el contexto de la colporrafia es importante tener en cuenta las diferentes estrategias quirúrgicas, cada vez menos invasivas, con correcciones sitio-específicas que permitan reparar el defecto anatómico, desaparecer los síntomas, disminuir el riesgo y la probabilidad de recidivas.

Abstract BACKGROUND: Pelvic organ prolapse is common in postmenopausal women. The definitive treatment when the anterior compartment is involved is surgical (anterior colporrhaphy). Here we describe the clinical results obtained using a modified anterior colporrhaphy technique in a patient with absence of prevesical fascia, POP-Q stage II, with involvement of the anterior compartment. CLINICAL CASE: 64-year-old female patient with a history of a previous colporrhaphy at the age of 56, pelvic organ prolapse with involvement of the anterior compartment. Gynaecological examination revealed anterior compartment involvement, specifically level II according to the new POP-Q classification. Based on the surgical history, anterior colporrhaphy with polyglactin 910 suture and vaginal colpopexy with polypropylene sutures using a suture capture device for native tissue repair was chosen. Surgical outcome was satisfactory. CONCLUSION: In the context of colporrhaphy, it is important to take into account the different surgical strategies, increasingly less invasive, with site-specific corrections that allow repair of the anatomical defect, disappearance of symptoms, reducing the risk and probability of recurrence.

Enfermedad pélvica inflamatoria en una paciente de 70 años: reporte de caso / Pelvic inflammatory disease in a 70-year-old patient. Case report

Resumen ANTECEDENTES: El absceso tubo-ovárico, como parte de la enfermedad pélvica inflamatoria, tiene características distintas en pacientes posmenopáusicas que en mujeres más jóvenes. CASO CLÍNICO: Paciente de 68 años, con antecedentes de cinco embarazos, tres partos y dos cesáreas, con vida sexual activa, diabetes mellitus tipo 2 e hipertensión arterial crónica, en control. Acudió a consulta debido a un dolor agudo en la fosa iliaca izquierda, con irradiación a la fosa iliaca derecha, acompañado de vómitos; esto disminuyó la toma pautada de antiinflamatorios no esteroideos y de los antibióticos. Con base en los reportes clínicos y de imagen se decidió la laparotomía exploradora en la que hubo hallazgos de: absceso pélvico multiseptado originado en el anexo derecho, con drenaje de material purulento de 250 cc. Se encontraron, además: síndrome adherencial severo, adenitis mesentérica, afectación del apéndice cecal con procesos inflamatorios reactivos y despulimiento del colon sigmoides, con sangrado de 500 cc. CONCLUSIONES: La enfermedad pélvica inflamatoria asociada con un absceso tubo-ovárico en una paciente posmenopáusica no es frecuente, quizá por ello a veces es infradiagosticada, lo que conduce a un aumento de la morbilidad y mortalidad.

Abstract BACKGROUND: Tubo-ovarian abscess as part of pelvic inflammatory disease has different characteristics in postmenopausal patients than in younger women. CLINICAL CASE: A 68-year-old woman with a history of five pregnancies, three deliveries and two caesarean sections, with an active sexual life, type 2 diabetes mellitus and chronic arterial hypertension under control. She presented with severe pain in the left iliac fossa with radiation to the right iliac fossa, accompanied by vomiting, which reduced the prescribed intake of non-steroidal anti-inflammatory drugs and antibiotics. Based on the clinical and imaging findings, an exploratory laparotomy was performed, which revealed the following: multiseptal pelvic abscess originating from the right adnexa with drainage of 250 cc of purulent material. There were also findings of: severe adhesive syndrome, mesenteric adenitis, involvement of the cecal appendix with reactive inflammatory processes, and sigmoid colon depulpation with bleeding of 500 cc. CONCLUSIONS: Pelvic inflammatory disease associated with a tubo-ovarian abscess in a postmenopausal patient is uncommon, perhaps because of this it is sometimes underdiagnosed, leading to increased morbidity and mortality.

Association between the serum adiponectin levels and body composition in perimenopausal and postmenopausal women / 解剖学报

Objective To investigate the relationship between serum adiponectin levels and body composition of perimenopausal and postmenopausal women in central and western Gansu province, and explore the influencing factors of adiponectin levels. Methods The body weight, body mass index(BMI), waist-to-hip, fat mass, percentage of body fat, visceral fat mass and muscle mass of 638 women(317 in perimenopausal period and 321 in postmenopausal period) in central and western Gansu were measured by bioelectrical impedance analyzer. Enzyme linked immunosorbent assay (ELISA)was used to measure serum adiponectin levels. Pearson correlation analysis and multiple liner regression were used to investigate the relationship between adiponectin levels and body composition. Results The body muscle mass of women living in central and western Gansu province showed a downward trend after menopause period compared to those who were in perimenopause. The waist circumference, waist-hip ratio, percentage of body fat, visceral fat mass of postmenopauseal women showed an increasing trend compared to perimenopausal. There were no significant differences in BMI, fat mass and serum adiponectin levels. Overall, serum adiponectin levels were positively correlated with body fat percentage and visceral fat mass, and negatively correlated with muscle mass, and the main influencing factors of serum adiponectin levels were visceral fat mass. Conclusion The main influencing factors of serum adiponectin levels in perimenopausal and postmenopausal women living in central and western Gansu province are the visceral fat mass.

Effects of denosumab on bone mineral density around proximal femoral prosthesis after total hip replacement in postmenopausal osteoporotic patients / 中国骨伤

OBJECTIVE@#To evaluate the effect of denosumab on bone mineral density around proximal femoral prosthesis after total hip arthroplasty(THA) in the postmenopausal osteoporotic patients.@*METHODS@#Fifty-four consecutive patients underwent unilateral primary THA were included in this retrospective study. Twenty-five patients received denosumab for osteoporosis as the treatment group, and the twenty-nine without denosumab were the control group. At 1 week, 3month, 6 months, and 12 months after THA, bone turnover markers and proximal femoral periprosthetic bone mineral density (BMD) were measured.@*RESULTS@#At 3, 6 and 12 months after operation, the level of TRACP-5b in the control group was significantly higher than that in the treatment group (P<0.05);the level of bone-specific alkaline phosphatase (BALP) between two groups showed significant difference in 12 months after operation (control group was higher than treatment group, P<0.05). The BMD of Gruen 1 and Gruen 7 decreased at 3, 6 and 12 months after operation compared with 1 week after operation. Comparing the treatment group and the control group, the differences of the the decrease of BMD in Gruen 1 and Gruen 7 were no significant at 3 months after surgery. In Gruen 1, Gruen 7 at 6 months after operation and Gruen 1, Gruen 7 at 12 months after operation, the decrease of BMD in the control group was significantly higher than that in the treatment group(P<0.05). It is suggested that desudumab could inhibit the loss of BMD after 6 months, and continuously show a protective effect on bone mass at 12 months after operation.@*CONCLUSION@#After THA in postmenopausal patients with osteoporotic femoral neck fracture, Desuzumab can reduce the loss of BMD around the proximal femoral prosthesis and effectively inhibit bone resorption.

Iron accumulation and its impact on osteoporotic fractures in postmenopausal women / 浙江大学学报（英文版）（B辑：生物医学和生物技术）

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.

Cost-utility analysis of denosumab and teriparatide in the treatment of postmenopausal osteoporosis in Chinese women / 中国药房

OBJECTIVE To evaluate the cost-effectiveness of denosumab and teriparatide in the treatment of postmenopausal osteoporosis in Chinese women， and provide reference for relevant decision-making. METHODS From the perspective of health system in China， Excel 2003 was used to establish Markov model， and cost-utility analysis was used to evaluate the cost- effectiveness of denosumab or teriparatide combined with Calcium carbonate D3 tablets in the treatment of postmenopausal osteoporosis in Chinese women. Pharmacotherapy effects were obtained with network meta-analysis， and cost and health utility value data were obtained from published literature. The model cycle was 1 year， and the simulation time limit was the patient’s lifetime. Univariate sensitivity analysis and probabilistic sensitivity analysis were used to evaluate the effects of model parameter changes on the robustness of the results. Through scenario analysis， the cost-effectiveness of domestic drug cost used as drug cost of terlipatide group was discussed； the influence of residual effects of teriparatide on the results and the cost-effectiveness of sequential use of desumamab after terlipatide withdrawal were also discussed. RESULTS The effect of denosumab regimen was better than that of terlipatide regimen [13.24 quality-adjusted life years （QALYs） vs. 12.96 QALYs]， with lower cost （51 224.64 yuan vs. 167 102.67 yuan）， denosumab regimen was the absolutely superior regimen. The results of single factor sensitivity analysis showed that the cost and discount rate of Terlipatide injection had greater impact on the results. The results of probability sensitivity analysis showed that when three times of China’s per capita gross domestic product （GDP） in 2021 was used as the threshold of willingness to pay， the probability of cost-effectiveness of denosumab regimen was 93.5%. The results of scenario analysis showed that， whether the drug cost of terlipatide regimen which was replaced by domestic drugs， or the residual effect of terlipatide was considered， or desulmonab was used sequentially after two years of terlipide treatment， denosumab regimen was always the absolute advantage regimen. CONCLUSIONS Denosumab combined with Calcium carbonate D3 tablets is more cost-effective than teriparatide combined with Calcium carbonate D3 tablets in the treatment of postmenopausal osteoporosis in Chinese women.

Mechanism of Zhibai Dihuang decotion in treating postmenopausal osteoporosis / 药学学报

In this study, the ovarian surgery (ovariectomy, OVX) was used to establish the osteoporosis mice model of primary menstruation, in order to evaluate the protective effects and mechanisms of Zhibai Dihuang decotion on postmenopausal osteoporosis (PMOP). The animal experimental protocol has been reviewed and approved by Laboratory Animal Ethics Committee of Jinan University (number: 20210315-03), in compliance with the Institutional Animal Care Guidelines. C57BL/6 mice were divided into five groups, including Sham group, OVX group, low (32 g·kg-1·day-1) and high dose (64 g·kg-1·day-1) of Zhibai Dihuang decotion groups, positive drug group (alendronate, 9.9 mg·kg-1·q3d). After modeling, mice were given medication intervention for 8 weeks, and then femoral and tibial tissues were taken to detect indicators such as bone microstructure, bone resorption, and oxidative stress. The experimental results showed that after Zhibai Dihuang decotion administration, the bone microstructure damage caused by OVX surgery was alleviated, and the relevant parameters bone mineral density (BMD), bone volume/total volume (BV/TV), trabecular number (Tb. N) and connectivity density (Conn. D) both significantly increased. At the same time, the number of TRAP positive osteoclasts decreased significantly, and the levels of proteins and genes related to osteoclast differentiation decreased, indicating that Zhibai Dihuang decoction could inhibit the increased activity of osteoclast caused by OVX. Afterwards, network pharmacology was used to construct the active compound action target network of Zhibai Dihuang decotion, and it was found that the target genes of its active ingredients were closely related to the oxidative stress pathway. Finally, the detection results of oxidative stress levels in bone tissues showed that after treatment with Zhibai Dihuang decotion, the levels of oxidative stress products 4-hydroxynonenal (4-HNE) and malondialdehyde (MDA) in bone tissues of mice significantly decreased, while the levels of antioxidant stress substance L-glutathione (GSH) increased. These above results indicated that Zhibai Dihuang decotion can regulate the level of oxidative stress in the body and inhibit osteoclast activity, which played a therapeutic role in PMOP, as well as provided theoretical basis for the prevention and treatment of PMOP with traditional Chinese medicine.

Bone turnover markers, hip bone geometry parameters and metabolic syndrome in community overweight postmenopausal women / 中华内分泌代谢杂志

Objective:To explore the changes of bone turnover markers and geometric parameters of hip bone in overweight postmenopausal women with metabolic syndrome(MS), as well as the influence of MS components. To analyze the association of these factors with the risk of fracture.Methods:A total of 505 overweight postmenopausal female patients who underwent health check-up in Lianhu Community Service Center, Danyang City, Jiangsu Province from January to December 2017 were selected. According to the MS diagnostic criteria of the International Diabetes Federation(2009), the patients were divided into MS group( n=331)and non-MS group( n=174). Blood samples were collected to determine the level of procollagen type 1 N-terminal propeptide(P1NP)and carboxy-terminal cross-linked telopeptide of type 1 collagen(CTX). Bone mineral density and hip bone geometry parameters were tested with dual-energy X-ray absorptiometry and hip structural analysis software. Results:The incidence of osteoporotic fracture and hip fracture in MS group was significantly higher than that in non-MS group(21.1% vs 13.8%, 4.8% vs 1. 1%, P<0.05). However, the bone mineral density of lumbar vertebra 1-4, femoral neck, and total hip in MS group was significantly higher than that in non-MS group, which remained after adjusting for age( P<0.05), but the difference disappeared after further adjustment for body mass index( P>0.05). The P1NP, CTX, femur strength index(FSI), section modulus(SM), and cross-sectional area(CSA)of MS group were significantly lower than those of non-MS group, the buckling ration(BR)was significantly higher than that in non-MS group, and the differences were still statistically significant after adjusting for age and body mass index( P<0.05). There was no significant difference in bone mineral density of lumbar vertebra 1-4, femoral neck, total hip, P1NP, and CTX between fracture group and non-fracture group in patients with MS. But FSI, SM, cross-sectional moment of inertia(CSMI), and CSA were significantly lower, BR was significantly higher( P<0.05) and femur strength decreased in patients with fracture. Regression analysis showed that high BR was an independent risk factor for fracture risk, while high FSI, SM, CSMI, and CSA were protective factors. Multivariate linear regression analysis showed that wasit circumference, diastolic blood pressure, and fasting plasma glucose were the main MS components affecting bone mineral density, bone turnover indexes, and hip bone geometry parameters. Conclusions:Overweight postmenopausal MS patients had decreased bone turnover rate, femoral strength, and relatively poor bone quality. Hip bone geometry parameters can be used as one of the methods to assess fracture risk in MS patients. Waist circumference, diastolic blood pressure, and fasting blood glucose are the important MS components affecting bone mass and bone quality.

Objective:To investigate the diagnostic value of serum CircRNA_0048211 expression level in postmenopausal osteoporosis (PMOP) and its correlation with bone-specific alkaline phosphatase (BALP), osteopontin (OPN), procollagen type I N-terminal propeptide (PINP) and β-crosslaps (β-CTX). Methods:Data of postmenopausal women who underwent physical examination in our hospital from January 2019 to December 2021 were collected. All subjects were measured bone mineral density (BMD) by dual-energy X-ray absorptiometry and divided into PMOP group, decreased bone mass group and normal bone mass group according to BMD level. The serum CircRNA_0048211, BALP, OPN, PINP and β-CTX levels were compared in each group. Binary logistic regression was used to analyze the risk factors of PMOP, the receiver operating characteristic curve (ROC) was drawn to analyze the diagnostic value of CircRNA_0048211, BALP, OPN, PINP and β-CTX on PMOP. The correlation between CircRNA_0048211 expression level and BALP, OPN, PINP and β-CTX was analyzed by Pearson correlation analysis. Results:A total of 218 patients were included in this study. Age is 60.52±6.83 years (range, 47-76 years), body mass index is 24.27±2.28 kg/m 2 (range, 22.18-25.73 kg/m 2) and menopausal time is 10.16±4.25 years (range, 2.30-21.80 years). There were 40 cases in PMOP group, 97 cases in osteopenia group and 81 cases in normal bone mass group. The serum CircRNA_ 0048211, BALP, OPN, PINP and β-CTX was significantly different between PMOP group, osteopenia group and normal group ( F=21.15, P<0.001; F=12.52, P<0.001; F=17.86, P<0.001; F=14.32, P<0.001; F=15.52, P<0.001). The serum CircRNA_0048211 level in PMOP group (0.37±0.08) were significantly lower than that of osteopenia group (1.05±0.46) and normal bone mass group (1.73±0.81), the difference was statistically significant ( P<0.05). The levels of BALP (28.42±7.35 μg/L), OPN (17.28±7.30 ng/ml), PINP (58.40±14.37 ng/ml) and β-CTX (1.52±0.28 μg/L) in PMOP group were significantly higher than those in osteopenia group (22.61±5.93 μg/L, 11.95±5.64 ng/ml, 49.16±11.24 ng/ml, 0.81±0.17 μg/L) and normal bone mass group (16.30±4.18 μg/L, 7.62±3.25 ng/ml, 35.48±7.12 ng/ml, 0.37±0.10 μg/L), the difference was statistically significant ( P<0.05). Binary logistic regression analysis showed that decreased CircRNA_0048211 expression level [ OR=3.53, 95% CI (2.73, 10.32)] was a risk factor for the occurrence of PMOP ( P<0.001). ROC curve showed that CircRNA_0048211≤0.76 has a diagnostic significance on PMOP, and its combination of BALP, OPN, PINP and β-CTX has the highest AUC [0.95, 95% CI (0.89, 1.00)] in diagnosing PMOP. Correlation analysis showed that CircRNA_0048211 expression level were negatively correlated with BALP, OPN, PINP and β-CTX ( r=-0.46, P<0.001; r=-0.80, P<0.001; r=-0.81, P<0.001; r=-0.69, P<0.001). Conclusion:The CircRNA_0048211 showed low expression in PMOP, which was negatively correlated with BALP, OPN, PINP and β-CTX. The combination of these five factors has certain clinical value in the diagnosis of PMOP.

Objective:To investigate the relationship between serum soluble receptor activator of nuclear factor-κB ligand (sRANKL), Omentin-1 levels and postmenopausal osteoporosis (PMOP) .Methods:A total of 310 menopausal patients admitted to Qingdao Municipal Hospital from Jun. 2017 to Jul. 2021 were selected, including 165 patients with PMOP and 145 women with simple menopause as the control group. Serum sRANKL and Omentin-1 levels were detected by ELISA. Bone mineral density and bone metabolism indexes [N-terminal propeptide of typeⅠprecollagen (PINP), bone alkaline phosphatase (BALP), β isomer of the C-terminal telopeptide of type Ⅰ collagen (β-CTX) and osteocalcin (OC) ] were compared between the two groups. The correlation between serum sRANKL and Omentin-1 levels and bone mineral density and bone metabolism indexes in PMOP patients was analyzed by Pearson. The predictive value of sRANKL and Omentin-1 to PMOP was analyzed by ROC curve. Logistic regression analysis of the influence of multiple factors on PMOP.Results:Compared with the control group (15.62±4.41) (42.56±8.53), the serum sRANKL level (26.63±8.12) was increased and Omentin-1 level (32.32±5.52) was decreased in PMOP group ( t=14.55, P<0.001; t=12.69, P<0.001). The serum sRANKL in PMOP group was positively correlated with PINP, β-CTX and OC, while the serum Omentin-1 level was negatively correlated with the above indexes by Pearson analysis. ROC curve showed that serum sRANKL and Omentin-1 had important reference significance in predicting PMOP. Logistic regression suggested that increased sRANKL and decreased Omentin-1 were risk factors for PMOP. Conclusion:Serum sRANKL and Omentin-1 in patients with PMOP are correlated with bone mineral density and bone metabolism, and have potential as diagnostic targets of PMOP.

Correlation between body fat mass indices and heart rate variability in postmenopausal women with high body mass index

Background: Well known facts for the rise in blood pressure, blood glucose, and cardiovascular diseases are the body fat mass that has become a major public health issue that correspond to health problems. Activation of sympathetic nervous system is directly proportional to body fat mass that results in an autonomic impairment. Aims and Objectives: The aim of the study is to compare body fat mass indices and heart rate variability (HRV) (Frequency Domain) in high body mass index (BMI) postmenopausal women. Materials and Methods: This research was directed on 104 postmenopausal women of age group 45–60 years grouped them into two. Group 1 having normal BMI (18.50–24.99) and Group 2 having high BMI >25.00 based on Asian’s classification for BMI. Approval from the Institutional Ethical Committee was obtained before beginning the study. Short-term HRV was measured in each participant by a 5-min frequency domain analysis. Results: Unpaired t-test was used to analyze all parameters of the study (control and study group). The result showed a lower level of parasympathetic and a higher sympathetic activity in the study group when matched against the control group. Conclusion: Body fat mass indices and HRV are inversely proportional in high BMI postmenopausal women and they more likely to suffer from cardiometabolic disorders in early.

Associations Between Menopausal Symptoms with Socio-economic, Demographic and Lifestyle Variables among Postmenopausal Women of Assam, Northeast India.

Background: Menopausal health refers to the various biological, physiological, and psychological changes and imbalances that occur as a result of the severity of symptoms. However, low oestrogen production causes various changes and declinations in women, which manifest as menopausal symptoms. Objectives: Present study determines the prevalence of menopausal symptoms and associations between socio-economic, demographic and lifestyle variables among postmenopausal women in Assam, Northeast India. Methods: The study was undertaken on 300 postmenopausal women using stratified random sampling. A pre-structured interview schedule was used to collect relevant data on socioeconomic, demographic, and lifestyle variables, as well as menopausal symptoms and related self-reported diseases, through a household survey and interview methods. Results: The mean age of menopausal women was found to be 47.08±2.38 years. Change in sexual desire (96.33%), profuse sweating with hot flush (61.67%), hot flush (60.00%), pain during sexual intercourse (46.33%), difficulties sleeping (37.00%), and lack of energy (39.67%) were the most common menopausal symptoms. There were significant associations recorded between various menopausal symptoms and age, education, first pregnancy age, age at menarche, family size, family type, parity, age at menopause, physical weakness, family income, and house condition (p <0.05). Conclusion: Menopausal symptoms were found to be more prevalent, and to reduce the population's health-related threat, more awareness, knowledge dissemination, and assistance are required, particularly among rural women.
