Accumulating evidence has demonstrated that nucleic acid-based therapies are promising for atherosclerosis. However, nearly all nucleic acid delivery systems developed for atherosclerosis necessitate injection, which results in rapid elimination and poor patient compliance. Consequently, oral delivery strategies capable of targeting atherosclerotic plaques are imperative for nucleic acid therapeutics. Herein we report the development of yeast-derived capsules (YCs) packaging an antisense oligonucleotide (AM33) targeting microRNA-33 (miR-33) for the oral treatment of atherosclerosis. YCs provide stability for AM33, preventing its premature release in the gastrointestinal tract. AM33-containing YCs, defined as YAM33, showed high transfection in macrophages, thus promoting cholesterol efflux and inhibiting foam cell formation by regulating the target genes/proteins of miR-33. Orally delivered YAM33 effectively accumulated within atherosclerotic plaques in ApoE -/- mice, primarily by transepithelial absorption via M cells in Peyer's patches and subsequent translocation via macrophages through the lymphatic system. Inhibition of miR-33 by oral YAM33 significantly delayed the progression of atherosclerosis. Moreover, oral treatment with YCs co-delivering AM33 and atorvastatin afforded significantly enhanced anti-atherosclerotic effects. Our findings suggest that yeast-based microcapsules represent an effective carrier for oral delivery of nucleic acids, either alone or in combination with existing drugs, offering a promising approach for precision therapy of atherosclerotic diseases.

Objective:To explore the current status of lipid-lowering therapy, the distribution of low-density lipoprotein cholesterol (LDL-C) levels and the risk assessment of cardiovascular events recurrence in patients with coronary heart disease (CHD) complicated by hypertension.Methods:This was a cross-sectional study. Patients with CHD combined with hypertension were hospitalized in the Department of Cardiology, General Hospital of Chinese People′s Liberation Army from August 5, 2008 to July 22, 2018 were included, and were divided into standard group and substandard group according to whether LDL-C reached the standard. Study data were obtained from inpatient coronary angiography records and electronic medical records database of Department of Cardiology, General Hospital of Chinese People′s Liberation Army, who used data from the first diagnosis of CHD. Clinical data of the selected patients were collected. Multivariate logistic regression model was used to analyze the associated factors of whether LDL-C reached the standard in CHD patients with hypertension.Results:A total of 18 800 patients were selected from 31 provinces/autonomous regions/municipalities directly under the central government in China, with Beijing accounting for the largest proportion (5 692 patients (30.28%)), followed by Hebei (3 621 patients (19.26%)), Henan (1 837 patients (9.77%)), and Shandong (1 618 patients (8.61%)). Among the selected patients, 1 493 had LDL-C<1.4 mmol/L (standard group), and 17 307 had LDL-C≥1.4 mmol/L (substandard group). Only 1 493 patients (7.94%) had LDL-C<1.4 mmol/L. There were 4 518 patients (24.03%), 4 366 patients (23.22%), 6 924 patients (36.83%) and 1 499 patients (7.97%) with LDL-C for 1.4-<2.0, 2.0-<2.5, 2.5-<3.8 and≥3.8 mmol/L levels, respectively. 17 855 patients (95.15%) were treated with statins, but only 1 334 patients (7.10%) were treated with statins and ezetimibe. Of the selected patients, 4 986 patients (26.52%) were at low risk, 6 515 patients (34.65%) were at intermediate risk, and 7 299 patients (38.82%) were at high risk. The combined lipid-lowering treatment rates of statin and ezetimibe in the middle-and high-risk patients were 7.43% (484/6 515) and 7.48% (546/7 299), respectively. The results of multivariate logistic regression analysis showed that increasing age, male, diabetes mellitus, stroke, and history of percutaneous coronary intervention (PCI) were positively associated with LDL-C standards in patients with CHD and hypertension, whereas obesity and acute myocardial infarction (AMI) were negatively associated with LDL-C standards (all P<0.01). Conclusions:The rate of achieving the standard LDL-C in patients with CHD combined with hypertension was low in China. Although the majority of patients had received moderate-intensity statin therapy, the proportion of statin-treated patients combined with ezetimibe was extremely low. The proportion of high-risk patients with recurrent cardiovascular events was higher in patients with CHD and hypertension in China, whereas the proportion of such patients receiving statin combined with ezetimibe lipid-lowering therapy was lower. This study also found that increasing age, male, diabetes mellitus, stroke, and history of PCI were positively associated with LDL-C standards, while obesity and AMI were negatively associated with LDL-C standards in patients with CHD and hypertension.

【Objective】 To share the experience of autologous platelet-rich plasma(PRP) combined therapy in successful treatment of refractory osteomyelitis with fractures in children. 【Methods】 One case of refractory osteomyelitis with fracture in children failed to respond to traditional treatment for more than 14 months. A total of 20 mL of whole blood was collected from the child, and 6 mL of PRP with 4 to 5 times concentration was prepared by secondary centrifugation. To prepare 2 cm×2 cm platelet concentrate gel (PG), 3 mL of PRP was mixed with a 0.3 mL activator which was then covered with an absorbable dressing. A three-way tube sprayed the remaining 3 mL of PRP and 0.3 mL activator into the surrounding tissues. 【Results】 The X-ray film of the patient followed up for 1 week showed that the fracture line was blurred, and the fracture end had obvious callus formation. The X-ray film reexamination at 4 months showed that the fracture end healed well, the fracture surface healed, and the osteomyelitis healed. 【Conclusion】 Autologous PRP has a good effect in the treatment of refractory osteomyelitis combined with fracture in children, which can provide a new method for clinical treatment.

Objective:To investigate the levels of dose to eye lens of interventional radiology workers in China from 2017 to 2019.Methods:The monitoring data on eye lens doses to the interventional radiology workers in 28 provinces across the country were collected from National Individual Dose Registry. Monitoring was carried out using TLDs on their left eyes and evaluated in terms of the personal dose equivalent Hp(3). By using Mann-Whitney U test and Kruskal-Wallis H test, statistical analyses were made of the average annual lens doses to interventional radiology workers in the hospitals of different types at different levels for different years. Results:From 2017 to 2019, the data on eye lens doses to 2 981 interventional radiology workers were collected, with doses ranging from below the minimum detectable level (MDL) to 64.48 mSv, the average annual eye dose of 1.38 mSv, and the annual doses incurred by 0.97% monitored workers exceeding the recently recommended dose limits, 20 mSv per year. The average annual lens dose monitored in general hospitals and in cancer hospitals were 1.33 and 1.77 mSv, respectively, without statistically significant difference ( P>0.05). The average annual lens dose in tertiary hospitals was 1.39 mSv, significantly higher than that in secondary hospitals where the value was 1.16 mSv ( Z=2.894, P<0.05). Conclusions:The estimated annual eye lens doses to the interventional radiology workers during 2017-2019 were in accordance with the current national standard GB 18871-2002, but with a few exceptions exceeding the current international standards. This means that there exists, to a certain degree, a potential risk for the eye lens in this work category to exceed the international limits. It is suggested to continue in effort to enhance the monitoring of eye lens dose for these workers and to increase risk awareness, and take effective protective measures so as to lower the level of eye lens doses.

Objective:To analyze the dose range distribution of abnormal result, the distribution of occupational categories, the incidence of abnormal result of different occupational categories, the causes of abnormal result and the factors influencing abnormal values, on the basis of investigated abnormal result of individual monitoring for occupationally external exposure, in order to provide the scientific basis for the formulation of the relevant regulations and standards and the hospital radiation protection management.Methods:The abnormal result of 389 radiation workers in medical institutions receiving annual individual doses each exceeding 1.25 mSv, reported in 2017 in 19 provinces, were collected and analyzed.Results:Dose distribution range of abnormal result were mainly between 1.25 and 5 mSv; diagnostic radiology workers accounted for the highest fraction, 59.64% of the totals; and interventional radiology workers had the highest incidence, 4.17‰ of abnormal result. The abnormal result was mainly caused by improper wearing or operating personal dosimeters; the abnormal values in the eastern regions were higher than those in other regions, with a median of 6.41 mSv; the abnormal values in the cause-unknown group was higher than those in other groups, with a median of 10.32 mSv.Conclusions:The publicity and training of radiation protection knowledge should be further strengthened to improve the protection awareness of radiation workers. The occupational exposure of interventional radiology workers should receive special attention.

Objective:To investigate the effect of genetic polymorphisms of TPMT*2 rs1800462, TPMT*3B rs1800460, TPMT*3C rs1142345, and NUDT15 rs116855232 on the tolerance of 6-mercaptopurine (6-MP) therapy in adult acute lymphoblastic leukemia (ALL) .Methods:A total of 216 adult patients who were diagnosed with ALL and treated with cyclophosphamide, cytarabine, and 6-MP [complementary and alternative medicine (CAM) regimen] from September 2015 to December 2019 were included. Polymorphisms were detected by TaqMan SNP Genotyping Assay. Combined with clinical data, the influence of genetic polymorphism on the tolerance of 6-MP in the treatment of ALL was analyzed.Results:Among the 216 patients, 185 (85.65%) patients had B-ALL and 31 (14.35%) patients had T-ALL. 216 (100%) patients had CC genotype for both TPMT*2 rs1800462 and TPMT*3B rs1800460. The number of TT and TC genotypes for TPMT*3C rs1142345 was 209 (96.76%) and 7 (3.24%) , respectively. The allele frequency was 1.62% for TPMT*3C rs1142345. The number of CC, CT, and TT genotypes for NUDT15 rs116855232 was 166 (76.85%) , 48 (22.22%) , and 2 (0.93%) , respectively. The allele frequency was 12.04% for NUDT15 rs116855232. The TPMT*3C rs1142345 mutant group (TC+CC genotype) had less transfusion volume of packed red blood cell than the wild group (CC genotype) ( P=0.036) , and the mutant group (TC+CC genotype) had a higher risk to develop hepatotoxicity (increased aspartate aminotransferase) than the wild group (CC genotype) ( OR=9.559, 95% CI 1.135-80.475, P=0.038) . The durations of white blood cells (WBC) <1×10 9/L and absolute neutrophil count (ANC) <0.5×10 9/L in the NUDT15 rs116855232 mutation group (CT+TT genotype) were longer than that in the wild group (CC genotype) ( P=0.005, P=0.007) , and the transfusion volume of apheresis-derived platelets in the mutant group (CT+TT type) was greater than that in the wild group (CC genotype) ( P=0.014) . Conclusion:Genetic polymorphism of TMPT and NUDT15 has an effect on the tolerance of 6-MP in the treatment of adult ALL. Detecting genotypes of patients with ALL before treatment helps to optimize the dosage of 6-MP, which may help shorten the bone marrow suppression duration and reduce blood transfusion volume.
