Osteoporosis is one of the common orthopaedic diseases,characterised by increased bone fragility due to reduced bone mass and microstructural degeneration,posing a great threat to patients’quality of life and safety.In recent years,Chinese medicine(natural)has had a unique advantage in the treatment of osteoporosis and has shown good efficacy.Autophagy is an inherent cellular survival mechanism for the removal and recycling of damaged proteins and organelles and plays an important role in maintaining the stability of the intracellular environment and organ function.Therefore,this article aims to provide a comprehensive review of these Chinese medicines(natural)for the treatment of osteoporosis through autophagy.They have been intensively studied and reported to have effects such as promoting osteogenesis and anti-bone resorption.The Chinese medicines include plants such as Cistanche deserticola,Epimedium,Curculigo orchioides Gaertn,Achyranthes bidentata Blume,Leonurus japonicus Houtt,Ginseng,Chuanxiong Rhizome,Eucommia ulmoides,Morindae Officinalis Radix,Curcuma longa,Polygoni Cuspidati Rhizoma et Radix,Anemarrhena asphodeloides Bunge,Salvia miltiorrhiza Bge and Pueraria Lobata,thus providing evidence for the use of alternative herbal therapies for the effective treatment of osteoporosis. 展开更多

Since the rapid spread of COVID‑19,our hospital has actively implemented the idea of“preventing the coronavirus from entering.”We paid close attention to details,rapidly carried out personnel and material management at all levels,and strived to do a good job in the prevention and control of the epidemic,so as to achieve zero infection.Patients’carers are an important part of quality care.Lacking of protection knowledge of infectious diseases would increase the risk of nosocomial infection.Therefore,our nursing department set up a team of epidemic prevention and control management.The team made the revision on contingency plans and care management regulations during the outbreak of COVID‑19,strengthened epidemic prevention and control knowledge training,carried out the supervision inspection work,and paid attention to humanized management measures to provide an important guarantee for victory over the COVID‑19. 展开更多

Mercury(Hg)enrichments in ancient sediments have been used as a proxy of volcanism,especially large igneous province(LIP)eruptions.However,considering the existence of other potential Hg sources besides volcanoes and the diverse factors(e.g.,organic matters,clay minerals,sulfide minerals and Fe oxides)that can affect Hg sequestration,there are considerable uncertainties to simply regard sedimentary Hg anomalies as signatures of volcanic activities.Mercury stable isotopes,a promising tool for tracing the origins and transformations of Hg,have been increasingly used for determining the causes of Hg spikes and understanding the geochemical behavior of Hg in the geologic record.To date,lots of researches have applied Hg concentrations and Hg isotopes to identify LIP volcanisms linking with significant geological events such as mass extinctions,ocean anoxic events and other environmental perturbations that mainly occurred in the Phanerozoic.However,the results in previous studies clearly show that not all Hg enrichments are derived from volcanic inputs,which emphasize the need for more caution in using Hg as a fingerprint of volcanism.With a better understanding of Hg isotopes in the future,there will be important implications for Hg isotopes to reconstruct volcanic activities in the rock records and their impacts on biological evolution. 展开更多

MgCl_(2)–NaCl–KCl salts mixture shows great potential as a high-temperature(>700°C)thermal energy storage material in next-generation concentrated solar power plants.Adding Mg into molten MgCl_(2)–NaCl–KCl salt as a corrosion inhibitor is one of the most effective and cost-effective methods to mitigate the molten salt corrosion of commercial Fe–Cr–Ni alloys.However,it is found in this work that both stainless steel 310 and Incoloy 800H samples were severely corroded after 500 h immersion test at 700°C when the alloy samples directly contacted with the over-added Mg in the liquid form.The corrosion attack is different from the classical impurity-driven corrosion in molten chloride salts found in previous work.Microscopic analysis indicates that Ni preferentially leaches out of alloy matrix due to the tendency to form MgNi_(2)/Mg_(2)Ni compounds.The Ni-depletion leads to the formation of a porous corrosion layer on both alloys,with the thickness around 204μm(stainless steel 310)and 1300μm(Incoloy 800H),respectively.These results suggest that direct contact of liquid Mg with Ni-containing alloys should be avoided during using Mg as a corrosion inhibitor for MgCl_(2)–NaCl–KCl or other chlorides for high temperature heat storage and transfer. 展开更多

Objective: To compare the efficacy of traditional Chinese medicine(TCM) based on Zheng differentiation with angiotensin receptor blocker/angiotensin-converting enzyme inhibitor(ARB/ACEI) in treating diabetic kidney disease(DKD) from the aspects of decreasing urinary microalbumin, declining 24-h urinary protein, reducing endpoint events, and renal function protection. Methods: The Chinese Biomedical Literature Database(CBM), the Chinese Academy of Sciences database(CNKI), the VIP Chinese journal database, Wanfang DATA, Medline database, Cochrane library, excerpt medical database(Embase), and Web of science were used for literature searching. The reviewer manager5.3 software was utilized to analyze the data. Results: Twenty-four studies including 1956 participants were involved in this review. Results showed that TCM had a better effect(mean difference [MD],-23.20, 95% confidence interval [CI],-30.60 to-15.79, P < 0.00001) than ARB/ACEI on lowering urinary albumin excretion rate(UAER) and urine albumin-to-creatinine ratio(MD-4.56 mg/mmol, 95% CI,-5.76 to-3.36, P < 0.00001). Moreover, the advantage of decreasing UAER was greater as the follow-up period become longer(P = 0.04). TCM also had a better effect in 24-h urinal protein, decreasing 0.36 g/24 h(95% CI,-0.45 to-0.27, P < 0.00001) more than the control in shorter follow-up period(ranged from 12 to 24 weeks) subgroup but only 0.08 g/24 h(95% CI,-0.13 to-0.03, P = 0.0006) in the longer follow-up period(>24 weeks) subgroup. TCM worked as well as ACEI/ARB in reducing endpoint events(relative risk, 0.67, 95% CI, 0.20–2.224, P = 0.51)and decreasing urinary albumin concentration(UAC)(MD,-16.50, 95% CI,-46.28–13.28, P = 0.28). As for protecting renal function, TCM had an equal effect to AECI/ARB in improving creatinine clearance ratio(MD,-3.30, 95% CI,-6.66–0.03, P = 0.05) or estimated glomerular filtration rate(MD, 1.00, 95% CI,-0.59–2.58, P = 0.22). However, TCM had a better effect in releasing the glomerular hyperfiltration state(MD,-9.64, 95% CI,-14.45 to-4.84, P < 0.0001). Conclusions: TCM based on Zheng differentiation can work as well as ACEI/ARB in treating DKD and even better in decreasing urinary microalbumin and releasing glomerular hyperfiltration. It is a good alternative treatment of DKD. 展开更多
