OBJECTIVE To investigate the impact of dapagliflozin on contrast-induced acute kidney injury （CIAKI） and prognosis in patients with diabetes mellitus type 2 （T2DM） and acute coronary syndrome （ACS） who underwent percutaneous coronary intervention （PCI）. METHODS Retrospective selection of data on T2DM patients with ACS who underwent PCI treatment in the Cardiology Department of Tianjin Chest Hospital from January 1st 2021 to December 31st 2022. The patients were divided into dapagliflozin group （96 cases） and control group （148 cases） based on whether they received dapagliflozin or not. Renal function indicators were measured for all enrolled patients before PCI and at 48 h and 1 week after PCI， including blood urea nitrogen （BUN）， serum creatinine （Scr）， estimated glomerular filtration rate （eGFR）， cystatin-C （Cys-C）， kidney injury molecule-1 （KIM-1） and β2-microglobulin （β2-MG）. All patients were followed up for at least 1 year. The incidence of CIAKI and major adverse cardiac event （MACE） during follow-up were recorded for both groups. Logistic regression was used to analyze the impact of dapagliflozin on the occurrence of CIAKI， while the Log-rank test was applied to compare the incidence of MACE between the two groups. Cox regression was employed to analyze the impact of dapagliflozin on prognosis. RESULTS At 48 h and 1 week after PCI， serum levels of Cys-C， KIM-1 and β2-MG were significantly lower in the dapagliflozin group compared to the control group （P＜0.05）. The incidence of CIAKI was lower in the dapagliflozin group compared to the control group （6.25% vs. 14.86%， P＝0.042）. Logistic regression analysis revealed that dapagliflozin was an independent protective factor against CIAKI （OR＝0.280， 95%CI 0.101-0.780，P＝0.015）. During the follow-up period， the incidence of MACE was lower in the dapagliflozin group compared to the control group （7.29% vs. 17.57%， P＝0.049）. Cox regression analysis indicated that dapagliflozin reduced the occurrence of MACE after PCI （HR＝0.374， 95%CI 0.161-0.866， P＝0.022）. CONCLUSIONS With adequate hydration， the use of dapagliflozin does not increase the risk of CIAKI following PCI in T2DM patients with ACS.

Mild cognitive impairment due to Alzheimer′s disease is an inevitable pathological stage in the early development of Alzheimer′s disease, which can be classified as "microlumps in the brain collaterals" in traditional Chinese medicine. Based on the theory of latent toxin blocking collaterals, this article discusses the etiology and pathogenesis, clinical sequelae, and traditional Chinese medicine intervention strategies for mild cognitive impairment due to Alzheimer′s disease. The onset of mild cognitive impairment due to Alzheimer′s disease is very similar to the latent pathogen theory, which states that "the latent pathogen is latent and then develops, the poison is deep and difficult to cure, and the development can be recognized but the latent pathogen cannot be detected." Combining clinical experience, our team believes that the basic nature of the disease is a slight deficiency and a slight excess of symptoms. A slight deficiency of the five zang viscera and six fu viscera as root and a latent toxin colling collaterals of qi, fire, phlegm, and blood stasis as manifestaion. These usually start from the qi depression and develop into phlegm coagulation and blood stasis, then end up in latent toxin and gradually become the healthy qi deficiency. Therefore, the deficiency of vital qi and incubation of evil, latent toxin blocking collaterals the pathogenesis of early intervention of this disease should be carried out, upholding the idea that "the upper workman treats the disease before it is diagnosed." The principle of strengthening vital qi to eliminate pathogenic factors, slowing down and promoting pathogenic factors elimination, establishing the method of supporting correctness and wisdom, simultaneously detoxifying and clearing the blood stasis, pattern differentiation as the main and the disease differentiation as the first, combining the disease and pattern, and adjusting the macroscopic and microscopic, focusing simultaneously on eliminating and replenishing, dispel phlegm and remove blood stasis, achieve a strong vital qi and the elimination of evil, and enhance intelligence, delay or even block the progression of mild cognitive impairment due to Alzheimer′s disease, improve patients′ quality of life, and provide a theoretical basis for the early clinical prevention and treatment of Alzheimer′s disease.

Objective:To analyze the research status of scleral lenses by bibliometric method based on the relevant collection of scleral lenses in the Web of Science database.Methods:Using the scleral lens-related literature collected in the Web of Science Core Collection database in the past 10 years (January 2013 to December 2022) as the object of analysis, bibliometric method and CiteSpace tools were used to conduct visual analysis of the literature.A comprehensive analysis of the volume of literature published, the distribution of countries and institutions, the information of core authors, the distribution of journals, and keyword clustering was performed.Results:A total of 340 articles were retrieved, which were published in 54 journals, with an average of 6.3 articles per journal, involving 301 authors.Research in this area covered 35 countries or regions, and 256 research institutions were involved.Discipline development was mainly in the United States, India, Spain and Australia.The main focus was on scleral lens (scleral contact lens), ocular surface disease, corneal edema, miniature scleral lens, etc.In the past 10 years, the trend of research hot topics in scleral lenses had shifted from the initial study of combining scleral contact lenses with ocular surface diseases to the subsequent study of prosthetic replacement of the ocular surface ecosystem, and the exploration of corneal clearance and shape.From 2013 to 2021, the main focuses were ocular surface diseases, scleral contact lenses, and corneal edema.After 2021, research on ocular surface diseases and keratoplasty declined.From January 2013 to December 2022, emergent keywords related to scleral lens mainly included scleral contact lens, transplantation, anti-host disease, prosthetic device in the first stage, artificial replacement of ocular surface ecosystem and irregular cornea in the second stage, and the research on corneal gap and characteristic shape in the third stage.Optical coherence tomography and corneal topography were commonly used examinations for scleral lens research and fitting.Conclusions:At present, the scleral lens is mainly used for dry eye, corneal diseases, corneal ectasia, keratitis, and corneal transplantation, especially after penetrating keratoplasty and refractive errors.Prosthetic replacement of the ocular surface ecosystem, and the exploration of corneal clearance and shape are the research hotspots in scleral lenses.

Objective:To investigate the efficacy of excimer laser atherectomy (ELA) combined with drug-coated balloon (DCB) in the treatment of femoropopliteal arteriosclerosis obliterans (ASO) and its influencing factors.Methods:The clinical data of patients with femoropopliteal ASO treated by ELA combined with DCB from July 2019 to March 2022 were retrospectively analyzed, including technical success rate, ankle-brachial index(ABI), primary patency rate and freedom from target lesion revascularization (TLR) rate. Cox regression was applied to analyze the risk factors affecting the decline in the rate of primary patency and freedom from TLR.Results:All 82 patients were treated with ELA+DCB. The technical success was 91.5%. The post-operative ABI (0.73±0.13) was significantly higher than preoperative ABI (0.39±0.11) ( t=35.26, P<0.001). The 24-month cumulative primary patency and TLR-free rates were 64.1% and 76.8%, respectively. Lesion length>15 cm ( HR=2.57, P=0.047) and severe calcification ( HR=3.26, P=0.021) were associated with loss of primary patency. Having diabetes ( HR=5.24, P=0.010) and a single postoperative outflow tract ( HR=4.18, P=0.008) were associated with a decrease in TLR-free rates. Conclusions:ELA combined with DCB for femoropopliteal ASO is safe and has good intermediate efficacy. Lesion length>15 cm and severe calcification were independent risk factors for primary patency rate, and diabetes and a single postoperative outflow tract were independent risk factors for TLR-free rate.

Objective To evaluate the efficacy and safety of laser-assisted balloon angioplasty(LABA)in treating patients with infrapopliteal arterial occlusion complicated by critical limb ischemia(CLI).Methods The clinical data of patients with infrapopliteal artery occlusion complicated by CLI,who were admitted to the Fuwai Central China Cardiovascular Hospital to receive LABA(LABA group)or balloon angioplasty alone(BA group)between January 2019 and December 2021,were retrospectively analyzed.The incidence of perioperative complications and postoperative clinical efficacy were compared between the two groups.Results A total of 32 patients received LABA therapy and 40 patients received BA alone.The technical success rate,the postoperative ankle-brachial index(ABI),the numerical value of postoperative ABI value deducting preoperative ABI value,the postoperative 24-month continuous improvement rate of clinical symptoms and the primary patency rate of target vessels in the LABA group were remarkably higher than those in the BA group(all P＜0.05).No procedure-related target vessel perforation,amputation,or death occurred in both groups.No statistically significant differences in the target vessel dissection,distal embolism,remedial stenting,and postoperative 24-month amputation-free survival existed between the groups(all P＞0.05).Conclusion For the infrapopliteal arterial occlusion complicated by CLI,LABA therapy is clinically safe and effective,and its mid-term efficacy is superior to BA alone.
