Objective:To evaluate the impact of sarcopenia on survival and treatment-related toxicity in postoperative recurrent esophageal squamous cell carcinoma (ESCC) patients treated with chemoradiotherapy.Methods:Clinical data of 147 patients with postoperative locoregional recurrent ESCC receiving chemoradiotherapy in Huai'an First People's Hospital from 2016 to 2017 were retrospectively analyzed. Pectoralis muscle area (PMA) was determined using routine pre-radiotherapy CT simulation scan above the aortic arch level. Sarcopenia was defined as a cut-off value of pectoralis muscle index (PMI) (PMA/height 2) <11.55 cm 2/m 2 for males and <8.69 cm 2/m 2 for females. The incidence of toxicity, 1- and 3-year overall survival (OS) rates were statistically compared between patients with and without sarcopenia. Results:Sarcopenia was detected in 49 of 147 (33.3%) patients. The incidence of grade 3-4 toxicities in sarcopenic patients was significantly higher compared to that in their counterparts without sarcopenia (40.8% vs. 18.4%, P=0.005). In addition, patients with sarcopenia had significantly worse 1-year (61.2% vs. 82.7%) and 3-year OS rates (10.2% vs. 28.6%) than those without sarcopenia (both , P<0.001). Multivariate analysis showed that sarcopenia was an independent prognostic factor for poor OS ( P<0.001). Conclusion:PMI based on CT simulation scan has prognostic value in postoperative locoregional recurrent ESCC patients treated with chemoradiotherapy, which probably serves as a novel diagnostic tool for sarcopenia.

Clustered regularly interspaced short palindromic repeats（CRISPR）/CRISPR associated nuclease 9 （CRISPR/Cas9） is a self-defense system found in bacteria and archaea that enables targeted gene editing based on the principle. Due to its universality， efficiency， and simplicity， CRISPR/Cas9 has been applied in the pathological mechanism and prevention and treatment of diseases in many fields. Cerebrovascular diseases and central nervous system diseases seriously endanger human health. Stroke is related to genetics， unhealthy living habits， chronic diseases， and other factors. The brain tissue structure is complex and the cell types are diverse. It is difficult for a universal gene editing platform to study target genes safely， specifically， and efficiently. Scholars have continuously improved and optimized gene editing technology， explored the potential and research methods of gene editing technology， and promoted the research process of brain science. After a brief introduction to the mechanism of CRISPR/Cas9， this paper mainly summarized the optimization of the system in the fields of cerebral science including delivery methods， adeno-associated virus assembly， and new nanomaterials. Its application in cerebrovascular research including vascular homeostasis， microglial homeostasis， angiogenesis， blood-brain barrier， and drug screening was also summarized. Finally， this paper prospected the development of CRISPR/Cas9 in traditional Chinese medicine， hoping to provide references for related research design.

ObjectiveTo observe the protective effect of Shenlian prescription on acute lung injury induced by particulate matter （PM） exposure in rats and explore the mechanism. MethodFifty male SD rats were randomly divided into the control group， model group， Shenlian low-dose group （4.32 g·kg^-1）， Shenlian high-dose group （8.64 g·kg^-1）， and roflumilast group （3.46 mg·kg^-1）， with 10 in each group. Pre-administration with drugs by gavage was performed for one week. On the 8^th and 11^th days， the control group was instilled with normal saline in the trachea and the other groups with PM suspension to establish a rat model of acute lung injury induced by PM exposure. After modeling， drugs were given continuously until the end of the experiment. Forty-eight hours after the last exposure， the lung function of rats was detected. Then the rats were sacrificed and the lung morphological changes and pathological changes by hematoxylin-eosin （HE） staining were observed. CD68 expression in lung was detected by immunohistochemistry， and the levels of lung injury markers surfactant protein A （SP-A） and Clara cell protein16 （CC16） in serum were detected by enzyme-linked immunosorbent assay （ELISA）. The mRNA expression of interleukin-1α （IL-1α）， IL-6， IL-18， and monocyte chemoattractant protein-1 （MCP-1） in lung tissue was measured by Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR）. ResultCompared with those in the control group， the rats in the model group had decreased lung function and obvious structural damage of lung tissue， PM deposition， and infiltration of CD68 positive cells. The expressions of IL-1α， IL-6， IL-18， and MCP-1 in lung tissue were increased （P<0.01）. Compared with the model group， Shenlian prescription low and high doses restored the rats' lung function injury（P<0.05，P<0.01）， improved lung morphological and pathological structure， and reduced PM deposition. Infiltration of CD68 positive cells in lung was not significantly decreased. The levels of inflammatory factors IL-1α， IL -6， IL-18， and MCP-1 in lung were lowered （P<0.01）. ConclusionShenlian prescription could protect the rats' lung injury caused by PM exposure， improve lung morphology， and reduce PM deposition and inflammatory factor expression.

With the rapid development of social economy， the number of patients with nervous system diseases has increased， and the incidence of the population has a trend of younger， which has a serious impact on life health and social economy. Artemisinin is an active antimalarial component extracted and isolated from Artemisia annua， a Chinese medicinal material. Artemisinin and its derivatives， in addition to the antimalarial effect， also have anti-parasitic， anti-fungal， anti-viral， hypoglycemic， hypolipidemic， anti-tumor， and anti-inflammatory effects， showing a wide range of pharmacological activities. In the past five years， research on the new pharmacological effects of artemisinin and its derivatives has been deepening， and the efficacy of artemisinin and its derivatives in nervous system diseases has attracted much attention， including anti-neuroinflammation， anti-oxidative stress， maintaining the stability of the blood-brain barrier， regulating the release of neurotransmitters， repairing neuronal damage， and promoting neuronal regeneration. These pharmacological effects indicate that artemisinin and its derivatives are potentially capable of neuroprotection. By sorting out literature on the pharmacological activity of artemisinin and its derivatives in nervous system during 2019－2024， this paper systematically summarized the protective effects of artemisinin and its derivatives against nervous system diseases such as stroke， neurodegenerative diseases， neuroimmunological diseases， neuralgia， and nervous system tumors. This review is expected to provide clues and evidence for new indication expansion of artemisinin drugs， innovative drug development， and clinical treatment of nervous system diseases.

The impact of air pollution on human health has always been a research hotspot in the global health field. Outdoor air pollutants composed of multiple components can enter the human body through various pathways. Cardiovascular diseases are a group of diseases caused by outdoor air pollutants. Studies have shown that the incidence of cardiovascular diseases， including hypertension， arrhythmia， and heart failure， is significantly increased among people exposed to air pollution environments. Air pollutants such as fine particulate matter， nitrogen dioxide， ozone， carbon monoxide， and sulfur dioxide are closely related to the occurrence of cardiovascular diseases， and short-term and long-term exposure causes different cardiovascular risks. By reviewing the relevant research reports from 2019 to 2024， this article summarizes the epidemiological evidence of cardiovascular diseases caused by different air pollutants. It generalizes the pathways through which air pollutants accelerate the progression of cardiovascular diseases. These pathways include oxidative stress， inflammatory response， thrombosis， extracellular vesicle release， endoplasmic reticulum stress， apoptosis， endothelial dysfunction， autonomic nervous system imbalance， and their interactions. Based on the different mechanisms of air pollution on cardiovascular diseases， the article analyzes the main progress in drug intervention and summarizes the roles of various active ingredients and compound prescriptions of traditional Chinese medicine in treating air pollution-related cardiovascular diseases， providing reference for the research on the mechanisms and drug interventions of air pollution-related cardiovascular diseases.
