RESUMEN
PURPOSE: Given the beneficial effects of sacubitril/valsartan on blood pressure generally, this study investigates its antihypertension effects in diabetes mellitus (DM) patients with primary hypertension specifically, and the effect of sacubitril/valsartan on glycolipid metabolism. METHODS: We conducted a randomized, open-label, active-controlled study to compare the antihypertension effects of sacubitril/valsartan in DM individuals with primary hypertension. The primary end point was reduction in mean systolic blood pressure (SBP) from baseline with sacubitril/valsartan vs. olmesartan at week 8. The secondary endpoints included the changes in diastolic blood pressure (DBP), daytime SBP/DBP, nighttime SBP/DBP, BP achievement (office sitting BP < 130/80 mmHg), and lipid profile. The trial was registered with chictr.org.cn (ChiCTR2200066428) on Dec 22, 2022. RESULTS: A total of 124 patients were included in the final analysis. SBP decreased to a greater extent in the sacubitril/valsartan group from baseline to 8 weeks [between-treatment difference: 3.51 mm Hg, 95% confidence interval (95% CI) 0.41 to 6.62 mm Hg, P = 0.03]. Furthermore, more patients achieved the blood pressure goal with sacubitril/valasartan (74.60% vs. 54.70%, P = 0.03). Multiple logistical regression analysis showed that sacubitril/valsartan was associated with BP achievement [odds ratio (OR) 0.33, 95% CI 0.14-0.73, P = 0.007], but the difference in SBP, DBP, day time SBP/DBP, and night time SBP/DBP reduction did not approach statistical significance. HbA1C1, total cholesterol, and low-density lipoprotein-cholesterol were lower than baseline in both groups (P < 0.05); however, there was no difference in the effects on glucose and lipid metabolism from sacubitril/valsartan compared to olmesartan. CONCLUSIONS: Sacubitril/valsartan not only provided superior BP reduction compared to olmesartan, it did so without adverse effects on glycemic control and lipid parameters in DM patients with primary hypertension.
RESUMEN
The aim of our study is to evaluate the association of rotational atherectomy (RA) operation procedural indices and baseline lipid parameters with the prognosis of the patients with severe coronary calcification who underwent RA. Our study population consists of 287 patients treated with RA in Fuwai Hospital from January 2013 to December 2019. We analyzed the patients' rotation procedural indices including the number of burrs, the size of burrs, approach site, the size of guiding catheter, along with the baseline level of lipoprotein(a) (Lp(a)), low-density lipoprotein-cholesterol (LDL-C) and high-sensitivity C-reactive protein (hs-CRP) to examine the association of these measurements with the prognosis of these patients using Cox regression analysis and Kaplan-Meier survival analysis. We find that during the follow-up period of 56.7 months with the median, the use of single burr in the patients who underwent RA was significantly associated with the occurrence of cumulative major adverse cardiac events (MACE) when compared with using non-single burrs [Hazard Ratio (HR) 0.43, 95% confidence interval (95% CI) 0.24-0.77, p = 0.004] from univariate Cox regression analysis; (HR 0.36, 95% CI 0.20-0.66, p = 0.001) from multivariate Cox regression analysis In addition, we find a higher event-free survival rate in the single-burr group after Kaplan-Meier survival analysis (Log rank p = 0.0033). However, there was no significant association of the size of burrs with the occurrence of MACE (HR 0.90, 95% CI 0.47-1.73, p = 0.76). Similarly, we find no significant associations between the approach site and the occurrence of MACE (HR 0.79, 95% CI 0.24-2.53, p = 0.69), the baseline Lp(a) (HR 1.07, 95% CI 0.76-1.49, p = 0.71), the level of LDL-C (HR 0.83, 95% CI 0.55-1.26, p = 0.38) or hs-CRP (HR 0.85, 95% CI 0.45-1.58, p = 0.60). We find that the patients who receive RA with a single burr have better outcomes than those who receive RA with non-single burrs. Moreover,we find that the number of burrs used in RA instead of the size of burrs, approach site, the size of guiding catheter, or baseline levels of Lp(a), LDL-C or hs-CRP had significant association with the prognosis of RA patients.

OBJECTIVE: To summarize the preliminary application experience of intraoperative ultrasound with burr hole probe in minimally invasive neurosurgery and to explore its application value. METHODS: Thirty-one patients who underwent intraoperative ultrasound guided puncture with burr hole probe in our center from August 2018 to May 2024 were collected, including 16 cases of ventriculoperitoneal shunt operation, 6 cases of assisted stereotactic needle biopsy, 3 cases of intracranial pressure probe implantation in lateral ventricle, 3 cases of brain abscess puncture for external drainage, and 3 cases of intracranial cyst puncture and peritoneal drainage. During the procedures, the burr hole probe was used to locate the intracranial targets and guide the puncture. The postoperative computed tomography (CT) scans or combined postoperative pathological results could verify the accuracy of puncture. In addition, the intervention effect and recovery status of patients were also recorded. RESULTS: The intraoperative ultrasound with burr hole probe could clearly display all the purposed targets and accurately guide the puncture procedures in all cases. All patients achieved satisfactory diagnostic and therapeutic results without new neurological dysfunction and serious complications. CONCLUSIONS: The intraoperative ultrasound with burr hole probe is an effective device for demonstrating intracranial structures. It not only enables minimally invasive and precise diagnosis or treatment of many neurosurgical diseases, but also is simple and safe to operate, which has important promotional value in the neurosurgery.

INTRODUCTION: Dyslipidemia significantly contributes to atherosclerotic cardiovascular disease (ASCVD). Patients with lipid-rich vulnerable plaques are particularly susceptible to cardiovascular complications. Despite available lipid-lowering therapies (LLTs), challenges in effective lipid management remain. AREAS COVERED: This article reviews monoclonal antibody (mAb) therapy in dyslipidemia, particularly focusing on vulnerable plaques and patients. We have reviewed the definitions of vulnerable plaques and patients, outlined the efficacy of traditional LLTs, and discussed in-depth the mAbs targeting PCSK9. We extensively discuss the potential mechanisms, intracoronary imaging, and clinical evidence of PCSK9mAbs in vulnerable plaques and patients. A brief overview of promising mAbs targeting other targets such as ANGPTL3 is also provided. EXPERT OPINION: Research consistently supports the potential of mAb therapies in treating adult dyslipidemia, particularly in vulnerable patients. PCSK9mAbs are effective in regulating lipid parameters, such as LDL-C and Lp(a), and exhibit anti-inflammatory and anti-thrombotic properties. These antibodies also maintain endothelial and smooth muscle health, contributing to the stabilization of vulnerable plaques and reduction in adverse cardiovascular events. Future research aims to further understand PCSK9 and other targets like ANGPTL3, focusing on vulnerable groups. Overall, mAbs are emerging as a promising and superior approach in dyslipidemia management and cardiovascular disease prevention.

Background: For the patients with acute coronary syndrome (ACS) undergoing percutaneous coronary intervention (PCI), dual antiplatelet therapy (DAPT) for at least 1 year is recommended in the guidelines to minimize the risk of stent thrombosis. Persistently uncovered stent strut means delayed neointima formation and extend the window of time in which the stent is prone to thrombosis. Previous studies showed that statins could improve post-stenting strut endothelial coverage for patients undergoing PCI. However, there are lack of evidences on whether early initiation of proprotein convertase subtilisin/Kexin type 9 monoclonal antibody (PCSK9mAb) after PCI in ACS patients can further improve the rate of stent strut coverage on the background of oral lipid-lowering therapy (LLT). Methods: This is a single-center, randomized trial to enroll 36 patients undergoing PCI with a clinical diagnosis of non-ST-segment elevation ACS. The baseline level of low-density lipoprotein cholesterol (LDL-C) of these patients are between 1.4 mmol/L and 3.4 mmol/L. Patients will be assigned to intensive lipid-lowering therapy (LLT) with PCSK9mAb group and conventional LLT without PCSK9mAb group for 12 weeks in a clinical follow-up setting according to 1: 1 randomization. the rate of stent strut endothelial coverage by optical coherence tomography (OCT) examination at 12 weeks after enrollment between the groups will be compared. Conclusion: This will be the first study to investigate changes in the rate of stent strut endothelial coverage under intensive LLT with PCSK9mAb by OCT examination in ACS patients undergoing PCI. The finding of this study will provide clinical evidence for future research about the hypothesis of a novel strategy of "intensive LLT (PCSK9mAb + statin ± ezetimibe) combined with shortened DAPT duration" for ACS patients undergoing PCI.Clinical Trial Registration: URL: https://www.clinicaltrials.gov.

RESUMEN
Refractory hypercholesterolemia (RH), including homozygous familial hypercholesterolemia (HoFH) and compound heterozygous familial hypercholesterolemia, is characterized by high levels of low-density lipoprotein cholesterol (LDL-C) despite existing cholesterol-lowering methods at maximal tolerable doses. Patients with RH have early onset and higher risk of atherosclerotic cardiovascular disease (ASCVD) under insufficient treatment. Therefore, it is urgent to seek new therapies to maintain the blood lipids in refractory hyperlipidemia at normal levels. Currently, new cholesterol-lowering strategies are on the market, not only at the protein level [i.e., bempedoic acid (inhibiting ATP-citrate lyase), alirocumab and evolocumab (monoclonal antibodies against PCSK9), evinacumab (monoclonal antibody against ANGPTL3)] but also at the transcript level [i.e., mipomersen (antisense oligonucleotide inhibiting ApoB), inclisiran (siRNA targeting PCSK9)], providing more options for RH patients to achieve their lipid-lowering targets. More RNA-based therapies targeting RH-related genes have been designed for the treatment. However, for a proportion of patients, especially those with LDLR deficiency, the available treatments are still insufficient. More recently, emerging genome engineering based on CRISPR/Cas9 techniques, and advanced delivery technologies such as lentiviral vectors, adenoviral vectors, adeno-associated viral vectors, lipid nanoparticles, and exosomes are being rapidly developed and implemented as novel therapies for RH. Gene therapy targeting RH-related genes has been successfully conducted in cells, mice, and non-human primates with high efficacy in lipid lowering and good tolerability. Especially the new generation of genome editing technique, base editing, performed in vivo with ideal lipid-lowering effect and limited occurrence of unwanted results. Excitingly, a phase I/II clinical study of LDLR gene replacement has been recently completed in RH patients, likely to be employed in clinical practice in the future. Furthermore, new targets for cholesterol reduction such as REV-ERB, G protein-coupled receptor, Ubiquitin specific peptidase 20 are continually being developed. This narrative review updates recent advances in treatment for RH, summarizes related clinical trials and preclinical studies, especially on the prospect of gene therapy.
RESUMEN
Postprocedural cardiac troponin I (cTnI) elevation commonly occurs in patients undergoing percutaneous coronary intervention (PCI); however, its prognostic value remains controversial. This study aimed to investigate the prognostic value of peak postprocedural cTnI in cardiac patients with or without three-vessel disease (TVD) undergoing complete PCI. A total of 1237 consecutive patients (77% males, mean age 58 ± 10 years) with normal baseline cTnI levels were enrolled, 439 patients (77% males, 59 ± 10 years) with TVD, and 798 patients (77% males, 57 ± 10 years) with single- or double-vessel disease (non-TVD). The primary outcome was the occurrence of major adverse cardiovascular events (MACE), defined as a composite of non-fatal MI, non-fatal stroke, unplanned revascularization, re-hospitalization due to heart failure or severe arrhythmias, and all-cause death. During the median follow-up of 5.3 years, a total of 169 patients (13.7%) developed MACE, including 73 (16.6%) in the TVD group and 96 (12.0%) in the non-TVD group (p = 0.024). After adjustment, the multivariate Cox analysis showed that hypertension (HR 1.50; 95% CI: 1.01-2.20; p = 0.042), TVD (HR 1.44; 95% CI: 1.03-2.02; p = 0.033), and cTnI ≥ 70× URL (HR 2.47; 95% CI: 1.28-4.78, p = 0.007) were independently associated with increased MACE during long-term follow-up. Further subgroup analyses showed that cTnI ≥ 70× URL was an independent predictor of MACE in TVD patients (HR 3.32, 95% CI: 1.51-7.34, p = 0.003), but not in non-TVD patients (HR 1.01, 95%CI: 0.24-4.32, p = 0.991). In conclusion, elevation of post-PCI cTnI ≥ 70× URL is independently associated with a high risk of MACE during long-term follow-up in patients with TVD, but not in those with non-TVD.
RESUMEN
Aim: The aim of this study was to evaluate the relationship between renal function and low-density lipoprotein cholesterol (LDL-C) goal achievement and compare the strategy of lipid-lowering therapy (LLT) among the patients with coronary artery disease (CAD) with different renal functions. Methods: In this study, we enrolled 933 Chinese patients with CAD from September 2020 to June 2021 admitted to the Cardiometabolic Center of Fuwai Hospital in Beijing consecutively. All individuals were divided into two groups based on their estimated glomerular filtration rate (eGFR). The multiple logistical regression analysis was performed to identify and compare the independent factors which impacted LDL-C goal achievement in the two groups after at least 3 months of treatment. Results: There were 808 subjects with eGFR ≥ 60 ml/min/1.73 m2 who were divided into Group 1 (G1). A total of 125 patients with eGFR <60 ml/min/1.73 m2 were divided into Group 2 (G2). The rate of LDL-C goal attainment (LDL-C <1.4 mmol/L) was significantly lower in G2 when compared with that in G1 (24.00% vs. 35.52%, P = 0.02), even though there was no significant difference in the aspect of LLT between the two groups (high-intensity LLT: 82.50% vs. 85.60% P = 0.40). Notably, in G1, the proportion of LDL-C goal achievement increased with the intensity of LLT (23.36% vs. 39.60% vs. 64.52% in the subgroup under low-/moderate-intensity LLT, or high-intensity LLT without proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitor (PCSK9i), or high-intensity LLT with PCSK9i, respectively, P < 0.005). In addition, in G2, there was a trend that the rate of LDL-C goal achievement was higher in the subgroup under high-intensity LLT (26.60% in the subgroup under high-intensity LLT without PCSK9i and 25.00% in the subgroup under high-intensity LLT with PCSK9i) than that under low-/moderate-intensity LLT (15.38%, P = 0.49). Importantly, after multiple regression analysis, we found that eGFR <60 ml/min/1.73 m2 [odds ratio (OR) 1.81; 95%CI, 1.15-2.87; P = 0.01] was an independent risk factor to impact LDL-C goal achievement. However, the combination strategy of LLT was a protective factor for LDL-C goal achievement independently (statin combined with ezetimibe: OR 0.42; 95%CI 0.30-0.60; P < 0.001; statin combined with PCSK9i: OR 0.15; 95%CI 0.07-0.32; P < 0.001, respectively). Conclusion: Impaired renal function (eGFR <60 ml/min/1.73 m2) was an independent risk factor for LDL-C goal achievement in the patients with CAD. High-intensity LLT with PCSK9i could improve the rate of LDL-C goal achievement significantly. It should be suggested to increase the proportion of high-intensity LLT with PCSK9i for patients with CAD, especially those with impaired renal function.
RESUMEN
RATIONALE: Presence of synchronous double hepatocelluar carcinoma (HCC) and intrahepatic cholangiocarcinoma (ICC) (sdpHCC-ICC) located separately within a single liver is extremely rare. The purpose of this study is to investigate the clinical, imaging, pathological characteristics, and prognosis of patients with sdpHCC-ICC, in order to enhance our understanding of the disease and improve diagnostic and therapeutic effect. PATIENT CONCERNS: A 49-year-old, female with the diagnosis of hepatitis B virus with obvious liver cirrhosis, was admitted to our hospital. On admission, the levels of α-fetoprotein and carbohydrate antigen 19-9 were found to be elevated. Abdominal ultrasonography and enhanced computed tomography revealed 2 solid masses located in segments (S) 4 and 6 of the liver, with malignant behaviors. DIAGNOSES: In the light of above investigations, preoperative diagnosis of multiple primary hepatocellular carcinomas was made. INTERVENTION: Hepatic resection of both segments was done. The resected specimens revealed the presence of well-defined tumors in segments 4 and 6 measuring 5.0âcm and 2.5âcm respectively. OUTCOMES: Histopathological examination confirmed the tumor of the 4th segment to be moderately and poorly differentiated ICC, and the tumor of the 6th segment to be poorly differentiated HCC. Immunohistochemically, the ICC in S4 was positive for CK19 and negative for Heppar-1, whereas the HCC in S6 was positive for Heppar-1 and negative for CK19. Unfortunately, metastasis to multiple organs and lymph nodes were observed 3âmonths later. The patient died of liver failure 16âmonths after surgery. LESSONS: The clinical characteristics of sdpHCC-ICC are usually atypical and nonspecific making its preoperative diagnosis quite difficult. Hepatitis B virus and hepatitis C virus infection were both the independent risk factor for the development of sdpHCC-ICC. In patients with chronic liver disease, careful observation with imaging is of utmost necessity. Tumor markers may also play a valuable role in the diagnosis. The definite diagnosis depends on pathological examination. Hepatic resection is considered the most effective mode of treatment. The prognosis of synchronous occurrence of double hepatic cancers is worse than either HCC or ICC, and the origin of the disease needs further study.

BACKGROUND: Accurate and early diagnosis of residual tumors or intrahepatic recurrences after TACE is critically needed for determining the success of treatments and for guiding subsequent therapeutic planning. This meta-analysis was performed to assess the efficacy of diffusion weighted imaging (DWI) with the quantitative apparent diffusion coefficient (ADC) value in diagnosing residual or recurrent hepatocellular carcinoma after transarterial chemoembolization (TACE). MATERIALS AND METHODS: A comprehensive literature search of PubMed, Embase, Web of Science, Scopus and the Cochrane Library database, from inception to July 2019, was conducted to select original studies on diagnosing residual or recurrent HCCs after TACE using DWI sequence with its ADC value. Two researchers independently chose study, extracted data, conducted meta-analysis, and evaluated methodological quality according to Quality Assessment of Diagnostic Accuracy Studies-2 (QUADAS-2) tool. RESULTS: Twelve studies comprising 624 patients and 712 tumors were finally included. The pooled sensitivity, specificity and AUC value of DWI in diagnosing residual or recurrent HCCs after TACE were 85% (95%CI: 74-92%), 83% (95%CI: 75-88%) and 0.90 (95%CI: 0.87-0.92), respectively. Residual or recurrent HCCs have significantly lower ADC value than necrotic tumors (MD = -0.48, 95%CI: - 0.69~ - 0.27, P < 0.01). CONCLUSION: This study demonstrated that DWI performed better in diagnosing residual or recurrent HCCs after TACE, and ADC value may serve as alternatives for further evaluation of residual or recurrent leisions in HCC patients after TACE.
