ObjectiveTo investigate the correlation between iron metabolism parameters and various syndrome types of unstable angina pectoris （UAP）. MethodsA cross-sectional study was conducted from October 2021 to October 2023， encompassing 213 patients diagnosed with UAP at Xiyuan Hospital of Chinese Academy of Chinese Medical Sciences. Additionally， 30 healthy individuals were selected as control cases. Single-factor analysis was used to investigate the differences in clinical data among different Traditional Chinese Medicine （TCM） syndrome types of UAP and their correlation with iron metabolism indices. The study conducted a comparative analysis of the aforementioned clinical data among patients with and without heat-toxic and blood-stasis syndrome. Logistic regression was used to analyze the correlation between TCM syndrome types and related factors. The receiver operator characteristic （ROC） curve was employed to assess the predictive value of iron metabolism indices， along with their sensitivity and specificity. ResultsCompared to those in the control group， serum iron （SI） and serum ferritin （SF） levels were significantly increased in the UAP group （P<0.01）， while transferrin （TRF） and total iron binding capacity （TIBC） levels were decreased （P<0.01）. However， there was no significant difference in unsaturated iron binding capacity （UIBC）. Multivariate binary Logistic regression analysis identified apolipoprotein A1 （ApoA1）， homocysteine （HCY）， high-sensitivity C-reactive protein （hs-CRP）， and SF as independent influencing factors for the UAP patients （P<0.05， P<0.01）. Additionally， statistically significant differences were observed in SI， SF， TRF， and TIBC among 213 patients with different TCM types （P<0.01）. Patients with heat-toxic and blood-stasis syndrome had higher SI and SF values than those without the syndrome （P<0.01）， while their TIBC and TRF values were lower （P<0.01）. Multivariate binary logistic regression analysis showed that SI and LDL-C levels were closely associated with the differentiation of heat-toxic and blood-stasis syndrome. ConclusionUAP patients often experience iron metabolism disorders， and the heat-toxic and blood-stasis syndrome are significantly correlated with iron metabolism parameters. The SI and LDL-C levels have high specificity and sensitivity in diagnosing heat-toxic and blood-stasis syndrome.

OBJECTIVE: To evaluate the clinical effect of "Tongdu Yisui" (unblocking the governor vessel and benefiting marrow) acupuncture and moxibustion on Meige syndrome. METHODS: Fifteen patients with Meige syndrome were treated with "Tongdu Yisui" acupuncture and moxibustion. Acupuncture was applied to Baihui (GV20), Dazhui (GV14), Shenzhu (GV12), Zhiyang (GV9), Jinsuo (GV8), bilateral Taixi (KI3), Zhaohai (KI6) and etc. Moxibustion was delivered at Jinsuo (GV8). After acupuncture and moxibustion at these body points, Jiao's scalp acupuncture was operated at bilateral chorea-tremor control area, and the patients were asked to walk for 20 min during needle retaining. Acupuncture and moxibustion were administered 20 min each time, once every two days, 3 times weekly and for 8 consecutive weeks. Assessments were conducted before treatment, after treatment, and follow-up at three months after treatment completion using the Burke-Fahn-Marsden dystonia rating scale (BFMDRS-M), abnormal involuntary movement scale (AIMS), and blepharospasm disability index (BSDI); and the clinical effect was evaluated after treatment. RESULTS: Compared before treatment, the scores of the sub-items of BFMDRS-M for eyes, mouth, speech and swallowing, and neck, as well as the total score of the scale, AIMS score and BSDI score decreased after treatment and during follow-up (P<0.05); the scores of the above indexes were not different statistically in comparison between the follow-up and after treatment (P>0.05). After treatment, 13 cases were effective, 2 cases were failed and the total effective rate was 86.7% (13/15). CONCLUSION "Tongdu Yisui" acupuncture and moxibustion can effectively alleviate motor symptoms and dysfunction of Meige syndrome and presents the sustained therapeutic effect.

eIF3a is a N ⁶-methyladenosine (m⁶A) reader that regulates mRNA translation by recognizing m⁶A modifications of these mRNAs. It has been suggested that eIF3a may play an important role in regulating translation initiation via m⁶A during infection when canonical cap-dependent initiation is inhibited. However, the death of animal model studies impedes our understanding of the functional significance of eIF3a in immunity and regulation in vivo. In this study, we investigated the in vivo function of eIF3a using eIF3a knockout and knockdown mouse models and found that eIF3a deficiency resulted in splenic tissue structural disruption and multi-organ damage, which contributed to severe sepsis induced by Lipopolysaccharide (LPS). Ectopic eIF3a overexpression in the eIF3a knockdown mice rescued mice from LPS-induced severe sepsis. We further showed that eIF3a maintains a functional and healthy immune system by regulating B cell function and quantity through m⁶A modification of mRNAs. These findings unveil a novel mechanism underlying sepsis, implicating the pivotal role of B cells in this complex disease process regulated by eIF3a. Furthermore, eIF3a may be used to develop a potential strategy for treating sepsis.

AIM: To investigate the pharmacokinetic properties of the main active components of Dalitong extract in SD rats after oral administration using UPLC-MS / MS. METHODS: An UPLC-MS / MS method was established to simultaneously detect tetrahydropalmatine, nobiletin and costunolide in the plasma and tissues of SD rats. The method was applied to investigate the pharmacokinetic characteristics and tissue distribution. RESULTS: After a single oral administration, the three active components were rapidly absorbed into the body, with a peak concentration (Cmax) of (13.73 ± 7.50), (27.01 ± 17.69) and (6.73 ± 29.94) ng / mL for tetrahydropalmatine, nobiletin, and costunolide, respectively. The time to reach the peak concentration (Tmax) was (1.40 ± 0.93), (0.63 ± 0.28) and (2.38 ± 8.81) h, respectively. The area under the curve (AUC) was (80.43±40.03), (41.30±28.69) and (303.90 ± 136.69) ng · h · mL

Refractory angina is characterized by recurrent and persistent angina with a duration of not less than three months， which is related to reversible ischemia and hypoxia caused by coronary stenosis and obstruction. It mainly involves obstructive coronary artery disease and non-obstructive coronary artery disease with coronary artery spasm and coronary microvascular dysfunction. “Stasis and toxin” play an important role in the pathogenesis of cardiovascular diseases. The pathogenesis of stasis and toxin is stubborn filthy turbidity featured by slow accumulation and sudden onset，and rapid changes，which coincides with the characteristics of refractory angina which is complex and changeable，prolonged and difficult to cure. The pathogenesis of refractory angina involves a combination of underlying deficiency and excessive manifestation， with "stasis and toxin" playing a crucial role as an important pathological factor in the whole process of refractory angina. Traditional Chinese medicine （TCM） employs a holistic approach known as "activating blood circulation and removing toxins"， which is supplemented by various methods to tonify Qi and warm Yang， nourish the kidneys and invigorate the spleen， clear heat and transform phlegm. This approach applies anti-inflammatory measures， regulates lipid metabolism， inhibits oxidative stress and thrombus formation， protects endothelial function in blood vessels， as well as establishes collateral circulation for the prevention and treatment of refractory angina. Therefore，based on the theory of "stasis and toxin"，combined with TCM theory and modern medical research，this paper discusses the pathogenesis of refractory angina and the prevention and treatment strategy of TCM，and elucidates the reasons for the difficulty in curing refractory angina and the relationship between refractory angina and common angina pectoris，coronary microvascular dysfunction，coronary artery spasm and obstructive coronary artery disease，hoping to provide certain theoretical basis and clinical ideas for the prevention and treatment of refractory angina with TCM.

OBJECTIVE To evaluate the quality and existing problems of Compound Paracetamol and Chlorphenamine Tablets for Infant. METHODS Using legal standards to inspect sampled samples, and several analytical methods were subsequently established or improved for the exploratory research on related substances, assay, dissolution, subdivision characteristics of scored tablets, and genotoxic impurities. RESULTS All samples met the regulatory specification, and the pass rate was 100%. However, the control for related substances was lacking, and the method for assay and content uniformity was defective. The exploratory studies showed that the assay and content uniformity met the requirements, and the risk of related substances and genotoxic impurities was acceptable. As a divisible tablet, the subdivision characteristics could not meet the requirements of the scored tablet, and the dissolution performance of some enterprise samples could not meet the requirements of similar products in foreign pharmacopoeias. CONCLUSION The overall quality of this product is adequate. However, due to the early time on the market, some quality attributes no longer meet the requirements of current regulations or relevant guidelines. The manufacturers should further optimize the prescription and production process, referring to foreign similar products. The current specification needs to be revised and improved.

Objective:To investigate the predictive value of procalcitonin to platelet ratio (PPR) and C-reactive protein to albumin ratio (CAR) in severe acute pancreatitis (SAP) and the value of SAP and concomitant acute liver injury (ALI).Methods:Total of 195 patients with AP from June 2021 to December 2022 from 374 patients were screened for inclusion in the study and were divided into non-severe acute pancreatitis (NSAP) and SAP groups. The ALI group was divided into non-acute liver injury (NALI) and ALI groups according to ALI criteria, and then into hepatocellular ALI subgroup, cholangiocellular ALI subgroup and mixed ALI subgroup. Laboratory tests for procalcitonin (PCT), C-reactive protein (CRP), albumin and platelet (PLT) were completed within 48 h. Risk factors for SAP, ALI and each subgroup of ALI were analysed by binary logistic regression. Subject work characteristic (ROC) curves were plotted and the optimal thresholds for PPR and CAR were calculated. The predictive value of PPR, CAR and their combination for SAP, ALI and each type of ALI was determined.Results:The AUCs for predicting SAP by plotting ROC curves and calculating the bedside index score of acute pancreatitis severity (BISAP score), PPR, CAR, PPR combined with CAR, PPR combined with BISAP score, CAR combined with BISAP score and combined PPR, CAR and BISAP score were 0.82, 0.85, 0.79 and 0.86. The areas under the ROC curves for PPR, CAR and combined prediction of ALI were 0.81, 0.85 and 0.88, respectively; the areas under the ROC curves for PPR, CAR and combined prediction of hepatocellular ALI were 0.93, 0.77 and 0.92, respectively; and the areas under the ROC curves for PPR, CAR and combined prediction of cholangiocellular ALI were 0.76, 0.76 and 0.77, respectively. The area under the ROC curves for PPR, CAR and combined prediction of mixed ALI were 0.83, 0.76 and 0.82Conclusions:Elevated PPR and CAR are risk factors for SAP and for the development of ALI in AP. PPR has better predictive value than CAR for hepatocellular and mixed ALI, and CAR has better predictive value than PPR for cholangiocellular ALI.

The result of liver transplantation (LT) for the treatment of hepatocellular carcinoma (HCC) is constrained by the high rates of tumor recurrence and metastasis. To remove this bottleneck, precise patient selection is crucial for individuals with HCC, and the goal of down-staging therapy is to transform patients exceeding transplantation criteria into suitable candidates. The difficulty in treating tumor recurrence and metastasis post-transplantation calls for more breakthroughs. Immunotherapy, as an emerging treatment modality, requires further exploration to enhance its safety and efficacy. The immunosuppression strategy is also a key factor in reducing tumor recurrence, requiring precise assessment and balanced control.

Atherosclerosis is a vascular disease characterized by arterial occlusion formed by the pathological accumulation of pathological vascular cells and apoptotic cell debris. Atherosclerotic vulnerable plaque is an important pathological basis for inducing severe thrombotic cardiovascular events， and the study of its etiology and pathogenesis has always been a hot issue in the field of cardiovascular research. Efferocytosis is a new type of programmed death cell removal， which refers to the process of macrophages phagocytosing and degrading apoptotic cells to prevent secondary necrosis. It is a key homeostatic mechanism in the body's physiological process. In the pathological state， the dysfunction of efferocytosis causes the pathological accumulation of apoptotic cells and necrotic debris， leading to the occurrence of secondary cell necrosis and the continuous release of intracellular toxic content and inducing inflammatory regression disorders and cholesterol metabolism disorders， which are closely related to the occurrence and development of atherosclerotic vulnerable plaques. The theory of ''blood stasis and toxin'' is an important theory of traditional Chinese medicine （TCM） to explain the occurrence and development of atherosclerosis. Atherosclerosis starts from the pathological state of blood stagnation. Prolonged blood stagnation leads to blood stasis and toxic substances. Blood stasis and toxic pathogens interact with each other in blood vessels and eventually form plaques in blood vessels. The theory of ''blood stasis and toxin causing a catastrophe'' is an important understanding of the occurrence and development of acute cardiovascular events. From the perspective of TCM theory， the pathophysiological mechanism of efferocytosis is similar to the etiology and pathogenesis of the ''blood stasis and toxin'' in TCM. Therefore， this paper took the theory of ''blood stasis and toxin'' as the breakthrough point to explore the mechanism of efferocytosis in atherosclerotic vulnerable plaques， and proposed a detoxification and blood circulation method to regulate cell burial to prevent and treat atherosclerotic vulnerable plaques. The research strategy aims to provide new ideas and theoretical basis for the prevention and treatment of atherosclerosis by detoxification and blood circulation.
