OBJECTIVE To investigate the effects of evolocumab combined with atorvastatin on post-percutaneous coronary intervention （PCI） efficacy and coronary microcirculation in patients with acute ST-segment elevation myocardial infarction （STEMI）. METHODS This retrospective cohort study included 194 hospitalized patients with acute STEMI who underwent PCI in the First Affiliated Hospital of Nanyang Medical College from Jan. 2022 to Dec. 2024. The patients were divided into control group （100 cases） and combination therapy group （94 cases） according to the different therapy plans. The control group was given Atorvastatin calcium tablets orally， at a dose of 20 mg， once a day. On the basis of the control group， the combination therapy group received an initial injection of Evolocumab injection 140 mg within 24 hours after PCI， followed by subsequent injections every 2 weeks. Both groups received continuous treatment for at least 30 days. Blood lipid indicators [total cholesterol （TC）， triglycerides （TG）， low-density lipoprotein cholesterol （LDL-C） and high-density lipoprotein cholesterol]， inflammation indicators [C-reactive protein （CRP） and interleukin-6 （IL-6）]， vascular Δ 基金项目河南省医学科技攻关计划项目（No.LHGJ20230971） endothelial function and microcirculation indicators [fibrinogen， ankle-brachial index （ABI） and nitric oxide （NO）]， cardiac function indicators [left ventricular ejection （LVEF）， left ventricular end-diastolic diameter and left ventricular end-systolic diameter] before treatment and after 30 days of treatment， as well as the occurrence of adverse reactions during the treatment， were compared between the two groups. RESULTS Before treatment， there were no statistically significant differences in the levels of the indicators of blood lipid， inflammation， vascular endothelial function and microcirculation， and cardiac function between the two groups （P＞0.05）. After 30 days of treatment， the levels of TC， TG， LDL-C， CRP， IL-6 and fibrinogen in both groups were significantly reduced compared to those before treatment within the same group. The levels of NO and LVEF in both groups， as well as ABI in the combination therapy group， were significantly elevated compared to those before treatment within the same group. Moreover， the improvements in the levels of TC， LDL-C， CRP， IL-6， fibrinogen and NO in the combination therapy group were more pronounced than those in the control group during the same period （P＜0.05）. There were no statistically significant differences in the incidence of liver function impairment， gastrointestinal adverse reactions， or the overall incidence of adverse reactions between the two groups （P＞0.05）. CONCLUSIONS Compared with atorvastatin alone， evolocumab combined with atorvastatin more effectively reduces the blood lipid levels， improves the inflammatory status， vascular endothelial function and coronary microcirculation in patients with acute STEMI after PCI， while the safety is comparable to that of atorvastatin alone.

Objective:To explore the influences of FibroScan detection on the pregnancy outcomes of pregnant rats transfected with hepatitis B virus and the growth of their offspring rats.Methods:Sixty SPF-grade SD rats with a male-to-female ratio of 5∶1 were selected，randomly divided the female rats into the groups of mid-pregnancy with hepatitis B，late-pregnancy with hepatitis B，normal mid-pregnancy，normal late-pregnancy，and control group，and the rats in the mid-pregnancy and late-pregnancy groups were subjected to FibroScan testing on the 10th and 15th days of gestation respectively. The number of offspring rats in each group was randomly reduced to 10 on the 3rd day after delivery，and the offspring rats were divided into the groups of mid-pregnancy with hepatitis B，late-pregnancy with hepatitis B，normal mid-pregnancy，normal late-pregnancy，and control group. The pregnancy outcome levels of pregnant rats were observed by adopting a stratified analysis strategy，including differences in weight changes，number of deliveries，fetal rat outcomes，lactation conditions，litter size，and litter weight. The growth levels of offspring rats，including differences in weight，body length，tail length，and the time of fur growth，tooth eruption，eye opening，and ear standing on the 21st day were observed，and the survival rate of the offspring rats was compared.Results:With regard to the pregnancy outcome levels of the pregnant rats，there were no statistically significant differences in weight changes during pregnancy among the five groups of pregnant rats［ F（4，45）=2.627，Adjusted P=0.222］. There were also no statistically significant differences in the number of deliveries，fetal rat outcomes，and lactation conditions（Adjusted P=1.000）. The number of deliveries［ F（4，21.095）=2.280，Adjusted P=0.222］and litter weight［ F（4，20.128）=2.159，Adjusted P=0.222］showed no statistically significant differences. After correction using the BH method，none of the indicators showed significant differences（ P>0.05）. In terms of the growth levels of the offspring rats，among the five groups of offspring rats，there were no statistically significant differences in body weight on the 21st day［H（4）=11.623，Adjusted P=0.135］，body length on the 21st day［H（4）=10.962，Adjusted P=0.135］，and tail length on the 21st day［H（4）=9.126，Adjusted P=0.058］. Besides，the differences in the time of fur growth，tooth eruption，eye opening，and ear standing［H（4）=0.000，Adjust P=1.000］showed no statistical significance. The survival rate on the 7th day，14th day，and 21st day was 100%，with no significant differences（Adjusted P=1.000）. After correction using the BH method，none of the indicators showed significant differences（ P>0.05）. Conclusion:FibroScan detection had no significant influences on the pregnancy outcomes of pregnant rats with hepatitis B or on the growth of their offspring rats in multiple stages，dimensions，and indicators，indicating that FibroScan detection is safe for pregnant rats. This research provides an animal experimental basis for the safe use of FibroScan in pregnant women with chronic HBV infection.

Objective The anti-inflammatory activity of medicinal plants in the six species of Selaginella genus were compared,and their effective parts and components were analyzed.Methods The total flavonoid content of various extraction parts and the main components of ethyl acetate part of Selaginella were determined by ultraviolet and high-performance liquid chromatography(HPLC),respectively.In vitro inflammatory cell models were constructed using Concanavalin A(ConA)and lipopolysaccharide(LPS)induced rat splenic lymphocytes and mouse macrophages,and cell viability was measured by CCK-8 methods.The nitric oxide(NO)level was determined by the Griess method,and the levels of IL-1β and TNF-α were determined by ELISA.The mRNA expression of inducible nitric oxide synthase(iNOS)and TNF-α,among other inflammatory factors,were detected by RT-PCR.Results The flavonoid content of the ethyl acetate part of Selaginella was relatively high,and biflavonoids such as amentoflavone was the main components.All the extraction parts of the six species of Selaginella showed no significant cytotoxicity.The ethyl acetate part,roberstonin-4'-methylether,and amentoflavone could significantly reduce the release of NO in RAW264.7 cells or lymphocytes,and the ethyl acetate part of Selaginella labordei were the most effective in both models.Selaginella labordei had a rich variety of biflavonoid components,with roberstonin-type biflavonoids relatively higher than other species.The mechanism of action was related to the inhibition of inflammatory factors such as IL-1β and TNF-α levels,the downregulation of mRNA expression of TNF-α,IL-6,IL-1β,iNOS,and others.Conclusion All six species of Selaginella have certain in vitro anti-inflammatory effects and Selaginella labordei showed stronger activity,with biflavonoids as their main active components.

Purpose To explore the forensic pathological features of deaths caused by craniocerebral injury in traf-fic accidents,in order to provide forensic practitioners with a more rigorous approach to identification.Methods A retrospective analysis was performed on 225 autopsy reports of traffic accident fatalities resulting from craniocerebral in-jury.The causes of death were classified,tabulated,and analyzed.Results Among the 225 autopsy reports,the main causes of death included primary brain injury,secondary brainstem injury,and complications.The main types of injuries craniocerebral injuries observed were skull fractures,cerebral hemorrhage,cerebral contusion,cerebral edema and so on.Conclusion The occurrence of craniocerebral injury is related to factors such as age,vehicle,collision speed,and road conditions,and there is an inherent regularity to these factors.Forensic practitioners should combine comprehesive and systematic pathological examinations,clinical data,and the inherent regularities of related factors to make objective,comprehensive,and accurate determinations of the cause of death in traffic accident-related craniocere-bral injuries.

Liver transplantation is one of the main treatments of early hepatocellular carcinoma (HCC). The recurrence of HCC after liver transplantation severely affects the long-term survival rate of the recipients. Targeted therapy and immunotherapy play a critical role in HCC downstaging, preventing disease progression, reducing recurrence rate, prolonging the survival and improving the quality of life. However, no consensus has been reached on the application of targeted therapy and immunotherapy in recipients undergoing liver transplantation for HCC, including indications, timing and dosage. In this article, clinical research progresses on the indications and timing of targeted therapy and immunotherapy before and after liver transplantation for HCC were reviewed, aiming to provide reference for prolonging the survival of recipients after liver transplantation for HCC.

Objective:To explore the strategy of preimplantation genetic testing for monogenic disorders (PGT-M) with variants of uncertain significance (VUS).Methods:Monogenic disorder couples who carried VUS and sought fertility counseling between 2018 and 2020 in Reproductive and Genetic Hospital of CITIC-Xiangya were recruited in this study. The pathogenicity of VUS was reanalyzed according to the Standards and Guidelines for the Interpretation of Sequence Variants released by the American College of Medical Genetics and Genomics (ACMG) and the Bayesian Classification. Those VUSs were reclassified as "pathogenic/likely pathogenic variants (P/LP)", "likely pathogenic VUS", "variants of uncertain significance", or "likely benign VUS". PGT-M was applied to families with VUS upgraded as "P/LP" or "likely pathogenic VUS" under the principle of couples fully voluntary and understanding the risks. We also followed up the developmental status of fetuses and the health condition of the born children.Results:1) A total of 25 variants were detected in 16 families with monogenic disorders, including 1 P, 3 LP, and 21 VUS. After reanalysis, 11 VUS and 7 VUS were upgraded as LP (52.4%) and "likely pathogenic VUS" (33.3%), respectively. Two VUS were still reclassified as "variants of uncertain significance"(9.5%), and 1 VUS was reclassified as "likely benign VUS" (4.8%). 2) PGT-M was implemented for 14 families with monogenic disorders, including 9 families with VUS upgraded as LP, 2 families with one LP/P and one "likely pathogenic VUS", and 3 families with only "likely pathogenic VUS". 3) Twelve healthy babies were born after PGT-M. Following up was done according to the onset age of diseases: 8 offsprings did not show the symptoms as probands, and 4 offsprings had not yet reached the age of onset and need continuous follow-up.Conclusion:It is necessary to actively search for new evidence and reanalyze the pathogenicity of VUS according to ACMG guidelines before PGT-M. Under fully informed consent of the patients, PGT-M can be carried out for VUS reclassified as "P/LP" and "likely pathogenic VUS", to reduce the risk of recurrence.
