Objective To investigate the mental health status and its influencing factors among elderly hypertensive patients from Rural Areas of Chuxiong and Honghe Prefecture in Yunnan. Methods Multi-stage random sampling method was adopted to select elderly hypertensive patients from rural Yi ethnic areas in Yunnan. Questionnaires were used to collect their basic information and mental health status. Multivariate logistic regression was performed to explore the influencing factors of mental health among the elderly hypertensives. Results 21.82% (209/958) of elderly people with hypertension have poor mental health status in Chuxiong and Honghe Prefecture, Yunnan. Age of 80-89 years (OR = 2.395, P<0.05) and over 90 years (OR = 3.293, P<0.05), as well as physical disability (OR = 2.037, P<0.05), were risk factors for poor mental health. Compared with those who rated their economic situation as very difficult, rating as somewhat difficult (OR = 0.490, P<0.05), moderate (OR = 0.632, P<0.05) and relatively affluent (OR = 0.344, P<0.05), having a spouse (OR =0.655, P<0.05), received full concern from the offspring (OR = 0.411, P<0.05) and maintain good relationships with offspring (OR = 0.339, P<0.05) were protective factors. Conclusions The mental health status of elderly people with hypertension is relatively poor in rural areas of Chuxiong and Honghe Prefecture in Yunnan Province. Special attention should be paid to the mental health of older and physically disabled elderly hypertensives. Economic and mental support from children was crucially important in improving the mental health of elderly hypertensive patients in rural areas of Chuxiong and Honghe Prefecture in Yunnan Province.

0bjective To explore the effectiveness of caregivers based on health education under the guidance of timing theory in the nursing of elderly patients after hip replacement. Methods By convenient sampling method, eighty elderly patients undergoing hip replacement were divided into control group and observation group, 40 cases in each group. The control group was given routine orthopedic care, and the observation group was based on health management under the guidance of the timing theory ( total hip replacement, TIR) based on routine orthopedic care. The Harris Hip Score, Activities of Daily Living Scale ( Barthel index), Caregiver Burden Inventory and Family Caregiver Task Inventory were used to compare and evaluate the application effect of health education of two groups of caregivers in the nursing of elderly patients after hip replacement. Results The patients were observed one month and three months after discharge, the Harris score and Barthel index of the observation group were significantly higher than those of the control group (P < 0.01). At discharge, 1 month after discharge and 3 months after discharge, the FCTI score ( P < 0.01) and CBI score ( P < 0.01) of family caregivers in the observation group were significantly lower than those in the control group. Conclusion Caregivers based on health education under the guidance of timing theory can effectively reduce the care burden of caregivers, enhance the care ability of caregivers, improve the rehabilitation effect of patients, and ameliorative the quality of life of patients.

Carbonyl compound has attracted great interest as the electrode material of polymer rechargeable battery owing to its potentially low-cost, sustainable, fast electrochemical reaction kinetics and multi-electron transfer capabilities. Among various carbonyl compounds, anthraquinone has been widely investigated in the past few years due to its excellent electrochemical stability and unique aromatic properties. Common anthraquinone materials often suffer from loss of capacity due to their low electronic conductivity and solubility in the organic electrolyte, which negatively affect the rate performance and cycling stability. Therefore, it is still challenging to develop anthraquinone based electrode with superior electrochemical performance. Many strategies have been attempted to address the above issues. Among them, the polymerization has been proved to be an effective strategy to reduce the solubility. Moreover, incorporating conductive additive with high specific surface area to form composites has also been demonstrated as an efficient approach to suppress dissociation dissolution and improve the electron transport in electrodes. Herein, a novel composite electrode material poly1,5-anthraquinone-coated carbon nanotube (CNT@P15AQ) was prepared via facile in-situ polymerization. After polymerization, the stability of anthraquinone in the organic electrolyte is significantly improved. In addition, the introduction of CNT can construct longrange electron transport pathways. Satisfactorily, the first discharge specific capacity of CNT@P15AQ composite electrode with 29% CNT mass fraction can reach 241.7 mA·h/g at a current density of 50 mA/g, which is 1.44 times higher than that of P15AQ. Meanwhile, the CNT@P15AQ composite electrode also exhibits excellent rate performance and cycle stability, which exhibits a reversible specific capacity of 148.5 mA·h/g at 10 C and retains 84.7% of its initial discharge capacity after 100 cycles at 1 C. High-performance CNT@P15AQ composite electrode with simple preparation method provides a broad application prospect of the next generation of rechargeable battery based on polymer electrode.

Objective To investigate the self-rated health status of elderly hypertensive patients in rural areas of Yi people, Yunnan province, and explore the influencing factors. Methods A convenience sample of 980 elderly hypertensive patients from rural areas where Yi ethnic groups gather in Yunnan Province was selected and their basic information, self-management and self-rated health level were investigated through a questionnaire survey. The relationship between self-management and self-rated health level was explored by Pearson correlation analysis. Finally, the influencing factors of the self-rated health level of elderly hypertensive patients were explored by multiple linear regression analysis. Results The participants reported low levels of self-rated health and selfmanagement behavior. There was no significant difference in self-rated health scores between Han and Yi hypertensive elders （ t = 1.458, P = 0.145). However, Han hypertensive elders had significantly higher self-management scores than Yi hypertensive elders （t = 2.577, P = 0.010）. Accepted education （b = 10.408, P < 0.001), good economic situation （b = 8.309, P < 0.001), and high self-management score （b = 1.911, P < 0.001） were protective factors for self-rated health, while living alone （b = -7.052, P = 0.039), having a disease in the past two weeks （b = -5.950, P = 0.049), being physically disabled （b = -17.445, P < 0.001), and having other chronic diseases （b = -14.014, P < 0.001） were risk factors for self-rated health. Conclusions The findings suggest that elderly hypertensive patients in rural Yi areas have poor self-rated health. Interventions are recommended to enhance their self-management skills and to address their specific needs, especially for those who live alone or have poor physical condition. [ABSTRACT FROM AUTHOR]

Naturally-occurring precipitate of traditional Chinese medicine (TCM) is generally considered to be a common phenomenon. The formation of naturally-occurring precipitate originates from the interactions among different chemical components during the decoction process. Previous literature has reported the existence of naturally-occurring precipitate in Sini decoction. In this study, seven pairs of acid-base non-covalent complexes in Sini decoction were characterized using cold spray ionization-mass spectrometry (CSI-MS) . The CSI device was built in house, where a stream of nitrogen gas was cooled by liquid nitrogen and used as the sheath gas, providing low-temperature ionization conditions for the MS analysis of the acid-base non-covalent complexes. The gas pipeline was equipped with a valve to regulate the nitrogen flow rate. Data acquisition was carried out using a quadrupole/Orbitrap high-resolution mass spectrometer operated in both full-scan MS and collision-induced dissociation MS/MS modes. Experimental results showed that the seven pairs of acid-base non-covalent complexes were unequivocally observed in positive and negative ionization modes. Mass spectrometric responses for each acid-base non-covalent complex varied with different chemical structures, binding abilities and ionization efficiencies. A representative pair of acid-base non-covalent complex (enoxolone/benzoylmesaconine) was selected to investigate the influence of the acid-base concentration ratio (3∶1, 2∶1, 3∶2, 1∶1, 2∶3, 1∶2, 1∶3) on the binding stoichiometry. The enoxolone/benzoylmesaconine complexes with the binding ratios of 1∶1, 1∶2, 2∶1 were observed, among which the mass spectrometric peak of the 1∶1 binding ratio was the most intensive. The non-covalent interactions of the representative enoxolone/benzoylmesaconine complex were analyzed using isothermal titration calorimetry (ITC) and computational chemistry. The thermodynamic parameters were obtained in the ITC experiment. In comparison with entropy change, the contribution of enthalpy change to Gibbs free energy was more significant, indicating that Van der Waals force and hydrogen bonding might be the main driving force in the formation of acid-base non-covalent complexes. This result was further confirmed by the docking model and simulation results of computational chemistry. Multiple hydrogen bonds derived from the interactions between specific atoms locating in the acid and base compounds promoted the self-assembly process. Moreover, Van der Waals attraction or repulsion force was generated between the C and H atoms at different positions, which in conjunction with hydrogen bonding interaction drove the formation of the acid-base non-covalent complexes. This study provides theoretical foundation and technical instruction for exploring the formation mechanism of naturally-occurring precipitate in Sini decoction. [ABSTRACT FROM AUTHOR]
