Mendelian randomization evidence for the causal effect of mental well-being on healthy aging.

Mental well-being relates to multitudinous lifestyle behaviours and morbidities and underpins healthy aging. Thus far, causal evidence on whether and in what pattern mental well-being impacts healthy aging and the underlying mediating pathways is unknown. Applying genetic instruments of the well-being spectrum and its four dimensions including life satisfaction, positive affect, neuroticism and depressive symptoms (n = 80,852 to 2,370,390), we performed two-sample Mendelian randomization analyses to estimate the causal effect of mental well-being on the genetically independent phenotype of aging (aging-GIP), a robust and representative aging phenotype, and its components including resilience, self-rated health, healthspan, parental lifespan and longevity (n = 36,745 to 1,012,240). Analyses were adjusted for income, education and occupation. All the data were from the largest available genome-wide association studies in populations of European descent. Better mental well-being spectrum (each one Z-score higher) was causally associated with a higher aging-GIP (ß [95% confidence interval (CI)] in different models ranging from 1.00 [0.82-1.18] to 1.07 [0.91-1.24] standard deviations (s.d.)) independent of socioeconomic indicators. Similar association patterns were seen for resilience (ß [95% CI] ranging from 0.97 [0.82-1.12] to 1.04 [0.91-1.17] s.d.), self-rated health (0.61 [0.43-0.79] to 0.76 [0.59-0.93] points), healthspan (odds ratio [95% CI] ranging from 1.23 [1.02-1.48] to 1.35 [1.11-1.65]) and parental lifespan (1.77 [0.010-3.54] to 2.95 [1.13-4.76] years). Two-step Mendelian randomization mediation analyses identified 33 out of 106 candidates as mediators between the well-being spectrum and the aging-GIP: mainly lifestyles (for example, TV watching and smoking), behaviours (for example, medication use) and diseases (for example, heart failure, attention-deficit hyperactivity disorder, stroke, coronary atherosclerosis and ischaemic heart disease), each exhibiting a mediation proportion of >5%. These findings underscore the importance of mental well-being in promoting healthy aging and inform preventive targets for bridging aging disparities attributable to suboptimal mental health.

Association of cardiovascular disease prevalence with BMD and fracture in men with T2DM.

BACKGROUND: Patients with type 2 diabetes mellitus (T2DM) are predisposed to cardiovascular disease (CVD). Bone mineral density (BMD) is linked to CVD, but most studies focused on women. Our analysis aims to explore the association of BMD and fracture with the prevalence of CVD in men with T2DM. METHODS: In this retrospective cross-sectional study, 856 men with T2DM were enrolled. BMDs at the lumbar spine (L2-4), femoral neck (FN), and total hip (TH) were measured by dual-energy X-ray absorptiometry (DXA). The CVD outcome was determined as the sum of the following conditions: congestive heart failure, coronary heart disease, angina pectoris, myocardial infarction, the requirement for coronary artery revascularization, and stroke. The relationship between BMDs and CVD was investigated by restricted cubic spline curves and logistic regression models. RESULTS: A total of 163 (19.0%) patients developed CVD. The restricted cubic spline curve revealed a linear and negative association between FN-BMD, TH-BMD, and CVD. After full adjustments for confounding covariates, the odds ratios were 1.34 (95% confidence interval [CI] [1.11-1.61], p < .05), 1.3 (95% CI [1.05-1.60], p < .05), and 1.26 (95% CI [1.02-1.55], p < .05) for each 1-SD decrease in BMDs of L2-4, FN and TH, respectively. T-scores of < -1 for BMD of L2-4 and FN were independently associated with CVD (p < .05). Subgroup analyses further supported our findings. CONCLUSIONS: The prevalence of CVD was inversely correlated with BMD levels in men with T2DM, particularly at the FN. We hypothesized that monitoring FN-BMD and early intervention would help reduce CVD risk in men with T2DM, especially those with hypertension.

Analysis of Banxia Houpo Tang Based on Ancient Literatures / 中国实验方剂学杂志

Banxia Houpo Tang is widely used in modern clinics with definite curative effect. It is one of the classic famous prescriptions in the Catalogue of Ancient Classic Famous Recipes（First Batch） published by the State Administration of Traditional Chinese Medicine（TCM） in 2018. Using bibliometrics methods，collect relevant literatures of Banxia Houpo Tang in ancient medical books，analyze and verify the origin，historical evolution，composition，prescription，function，dosage，artillery，preparation method and decoction method of prescription. A total of 259 related ancient literature data were obtained，involving 107 TCM books. The inductive analysis found that Banxia Houpo Tang originated from ZHANG Zhong-jing's Synopsis of the Golden Chamberin the Han dynasty and consisted of the five flavors of Pinelliae Rhizoma，Magnoliae Officinalis Cortex，Poria，Perillae Folium and Zingiberis Rhizoma Recens. Houpo Tang，Qiqi Tang，Siqi Tang，Daqiqi Tang and other synonyms have appeared in the records of medical records of all dynasties. The prescription composition，preparation method and decoction method are used by later generations of medical practitioners. The analysis of related prescriptions is also rarely disputed. The dosage of drugs used in Banxia Houpo Tang can be calculated as 1g or 3 g. The drug processing method is different from the original one. Pinelliae Rhizoma should choose Pinelliae Rhizoma Praeparatum Cum Zingibere et Alumine and Magnoliae Officinalis Cortex as "Jianghoupu". The rest of the drug processing methods respect the 2015 edition of Chinese Pharmacopoeia. The cardiology of its treatment has also been extended and expanded. In addition to the symptoms of "burning in the pharynx" recorded by the original party，this side can also be used for heart diseases such as heartache，chest tightness，sorrow，vomiting，choking noisy and other spleen and stomach disease syndrome and spermatorrhea，turbidity，scorching and other lower coke disease syndrome.

Textual Research and Suggestions on Dosage of Pinelliae Rhizoma in Famous Classical Formulas / 中国实验方剂学杂志

Pinelliae Rhizoma is a toxic traditional Chinese medicine, and its dose differs greatly between at ancient and modern times, so that it is difficult for researchers to determine its dosage during research and development of famous classical formulas. According to the literature research, it is found that the dose of Pinelliae Rhizoma in famous classical formulas has undergone a process from large to small. Based on the principle of " following the classic and conforming to pharmacopoeia" , and in combination with the modern actual situation, the reasonable dose of Pinelliae Rhizoma in the 17 formulas from the Catalogue of Ancient Famous Classical Formulas (The First Batch) is determined. According to the records of the original book, the evolution of past dynasties and the consideration of the current clinical application, dosage regimen and administration methods of the 17 famous classical formulas and so on, the authors suggested that the dosages of Pinelliae Rhizoma in Banxia Houpotang and Maimendong Tang are 15.0 g, its dosages in Wendantang and Sangbaipi Tang are 6.0 g, dosages of Pinelliae Rhizoma in Xuanfu Daizhe Tang, Zhuye Shigaotang, Banxia Xiexintang, Gancao Xiexintang, Huangliantang, Gualou Xiebai Banxiatang, Houpo Mahuangtang and Jinshui Liujunjian are 7.5 g, the dosages of Pinelliae Rhizoma in Zhurutang, Shengyang Yiweitang and Yangweitang are 6.7, 4.5, 5.0 g, respectively, dosages of Pinelliae Rhizoma in Banxia Baizhu Tianma Tang and Huopo Xialing Tang are 5.6 g.

Discussion on Use of Pinelliae Rhizoma Processed Products in Famous Classical Formulas / 中国实验方剂学杂志

There are 17 formulas containing Pinelliae Rhizoma in the Catalogue of Ancient Famous Classical Formulas (the First Batch), most of which are only labeled with " washing with decoction" or without any processing method, which is inconsistent with the current use requirements and brings confusion to research and development of related famous classical formulas. Through combing the records of famous classical formulas in the original book, contemporary works and later works, the usage of processed products of Pinelliae Rhizoma in the evolution of past dynasties was contrasted, and the efficacy, indications and compatibility significance of different formulas were analyzed, according to the principle of " respecting the ancient but not confining the ancient" , the authors suggested that the 17 famous classical formulas should use the processed products of Pinelliae Rhizoma in the 2015 edition of Chinese Pharmacopoeia, including Pinelliae Rhizoma Praeparatum, Pinelliae Rhizoma Praeparatum cum Zingibere et Alumine and Pinelliae Rhizoma Praeparatum cum Alumine. Among them, Pinelliae Rhizoma Praeparatum cum Zingibere et Alumine should be used in Banxia Xiexintang, Gancao Xiexintang, Huangliantang, Xuanfu Daizhe Tang, Zhuye Shigaotang, Banxia Houpotang, Maimendong Tang, Gualou Xiebai Banxiatang, Wendantang, Zhurutang, Jinshui Liujun Jian and Yangweitang, Pinelliae Rhizoma Praeparatum should be used in Shengyang Yiweitang, Houpo Mahuangtang, Banxia Baizhu Tianma Tang and Huopo Xialing Tang, and Pinelliae Rhizoma Praeparatum cum Alumine should be used in Sangbaipi Tang.
