Precancerous lesions of gastric cancer （PLGC） are a group of pathological changes caused by abnormalities in the structure， morphology， and differentiation of gastric mucosal epithelial cells. Since the early symptoms are hidden and non-specific， PLGC is not easy to be diagnosed and it has often developed into intermediate or advanced gastric cancer once being diagnosed and missed the best time for treatment. Accordingly， the incidence of this disease is increasing year by year， which lifts a heavy burden on the patients. The pathogenesis of PLGC is complex， involving inflammatory microenvironment， bile reflux， glycolysis， autophagy， and apoptosis. Currently， PLGC is mainly treated with anti-inflammatory and endoscopic therapies， which are difficult to curb the development of PLGC. Therefore， seeking a safe and effective therapy is an important topic of modern research. Traditional Chinese medicine （TCM）， characterized by treatment based on syndrome differentiation and a holistic view， exerts effects via multiple pathways， mechanisms， and targets. Recent studies have confirmed that TCM can regulate the phosphatidylinositol 3-kinase/protein kinase B/mammalian target of rapamycin （PI3K/Akt/mTOR）， Wnt/β-catenin， Sonic Hedgehog， nuclear factor-κB （NF-κB）， Janus kinase/signal transducer and activator of transcription （JAK/STAT）， hypoxia-inducible factor-1α （HIF-1α）， neurogenic locus notch homolog protein （Notch）， nuclear factor E₂-related factor 2 （Nrf2） and other signaling pathways. By targeting these pathways， TCM can inhibit aerobic glycolysis， reduce oxidative stress， repair the inflammatory microenvironment， regulate cellular autophagy， and promote vascular normalization， thereby delaying or reversing PLGC. However， few researchers have systematically summarized the TCM regulation of PLGC-associated pathways. By reviewing the relevant articles at home and abroad， this paper summarized the roles of the above signaling pathways in the development of PLGC and the research progress in the regulation of signaling pathways by TCM in the treatment of PLGC， with a view to providing a new theoretical basis for the clinical research on PLGC and the drug development for this disease.

The precise and rapid monitoring of multiple organ dysfunction is crucial in drug discovery. Traditional methods, such as pathological analysis, are often time-consuming and inefficient. Here, we developed a multiplexed near-infrared window two (NIR-II) fluorescent bioimaging method that allows for real-time, rapid, and quantitative assessment of multiple organ dysfunctions. Given that existing probes did not fully meet requirements, we synthesized a range of NIR-II hemicyanine dyes (HDs) with varying absorption and emission wavelengths. By modifying these dyes, we achieved high spatial and temporal resolution imaging of the liver, kidneys, stomach, and intestines. This method was further applied to investigate disorders induced by cisplatin, a drug known to cause gastric emptying issues along with liver and kidney injuries. By monitoring the metabolic rate of the dyes in these organs, we accurately quantified multi-organ dysfunction, which was also confirmed by gold-standard pathological analysis. Additionally, we evaluated the effects of five aristolochic acids (AAs) on multiple organ dysfunction. For the first time, we identified that AA-I and AA-II could cause gastric emptying disorders, which was further validated through transcriptomics analysis. Our study introduces a novel approach for the simultaneous monitoring of multi-organ dysfunction, which may significantly enhance the evaluation of drug side effects.

Objective:To investigate the value of left ventricular systolic synchrony assessed by gated myocardial perfusion imaging(GMPI)in predicting major adverse cardiovascular events(MACE)in elderly patients with coronary heart disease(CHD).Methods:In this retrospective study, clinical data from elderly patients who had completed a two-day assessment of resting-loading GMPI between September 2012 and February 2014 in Beijing Hospital were collected, including the summed stress score(SSS)for total ischemic burden, measured by GMPI, left ventricular ejection fraction(LVEF), peak filling rate(PFR), phase band width(PBW), phase standard deviation(PSD)and phase entropy(PE).Follow-up of MACE was conducted.Independent risk factors for MACE were analyzed using a multifactorial Cox proportional hazards regression model, and the cumulative MACE incidence was analyzed using the Kaplan-Meier survival curve.Results:A total of 427 subjects were enrolled, including 200(46.8%)men, with a mean age of 74.1±6.5(60-92)years and 323(75.6%)aged ≥ 70 years.The median follow-up time was 54.7 months.At the end of follow-up, MACE occurred in 47 patients(11.0%).Compared with the group without MACE, the incidences of hypertension, hyperlipidemia, and hyperuricemia were significantly higher( χ2=5.20, 5.62, 3.86, all P<0.05), LVEF and PFR were significantly lower( t=-5.51, -5.23, both P<0.001), and SSS, PSD, PBW, and PE were significantly higher( Z=4.78, t=5.14, 5.78, 5.62, all P<0.001)in the MACE group.The results of Cox proportional hazards regression model analysis suggested that age ≥ 70(hazard ratio: 2.57, 95% CI: 1.08-6.13), abnormal perfusion(hazard ratio: 2.60, 95% CI: 1.31-5.15), increased PSD(hazard ratio: 3.72, 95% CI: 1.72-8.05)and increased PE(hazard ratio: 4.09, 95% CI: 1.94-8.63)were independent risk factors for the occurrence of MACE(all P<0.05).Further analysis on 323 patients ≥ 70 years indicated that abnormal perfusion(hazard ratio: 2.96, 95% CI: 1.40-6.26), increased PSD(hazard ratio: 3.51, 95% CI: 1.56-7.89), and increased PE(hazard ratio: 4.49, 95% CI: 2.08-9.71)were independent risk factors for MACE( P<0.05 for all). Conclusions:Parameters of GMPI systolic synchrony analysis can very well identify the population at high risk of MACE in elderly patients with CHD.

Objective:To analyze the application effect of health education based on real-life experience in the rehabilitation nursing of elderly patients with femoral neck fractures.Methods:Using the convenient sampling method, a total of 116 elderly patients with femoral neck fractures admitted to the First Affiliated Hospital of Zhengzhou University from August 2022 to June 2023 were selected as the research objects. The patients were divided into the control group and the observation group using the random number table method, with 58 cases in each group. Patients in the control group received routine health education, while patients in the observation group received health education based on real-life experiences in addition to the control group. The knowledge, attitude and practice of femoral neck fractures, self-care ability and limb function of the two groups before and after intervention, as well as the treatment compliance of the two groups were compared.Results:After intervention, the score of knowledge, attitude and practice level of femoral neck fractures in two groups were higher than those before intervention, and the scores of all dimensions in the observation group were higher than those in the control group, and the differences were statistically significant ( P<0.05). After intervention, scores of Exercise of Self-Care Agency (ESCA) and Harris hip joint function of patients in both groups were improved and the scores of the observation group were higher than those of the control group, and the differences were statistically significant ( P<0.05). The cognitive score of functional training, compliance score of functional training and compliance score of discharge follow-up in the observation group were higher than those in the control group, and the differences were statistically significant ( P<0.05) . Conclusions:Health education based on real-life experiences can effectively improve the knowledge, attitude and practice level, self-care ability and treatment compliance of elderly patients with femoral neck fractures. It can effectively promote the recovery of limb function in patients and is worthy of clinical application.

Lung cancer is one of the most common malignant tumors in the world， with its morbidity and mortality ranking at the top. The early symptoms are not obvious， and the biological structure is complex， so many patients have missed the optimal treatment time. At present， the treatment of lung cancer in modern medicine is dominated by first-line chemotherapy and surgical treatment with platinum-containing regimen， which has relatively large side effects， poor prognosis， and a high risk of metastasis and recurrence. With the gradual rise of targeted therapy and immunotherapy for lung cancer， the overall recovery of patients with lung cancer is still poor and the survival rate is low， despite more abundant treatment methods. From the perspective of holistic concept and syndrome differentiation， traditional Chinese medicine （TCM） plays an important role in the prognosis of tumor patients， with many targets， a wide range and light toxic and side effect. Modern studies have shown that the occurrence and development of lung cancer are closely related to the abnormality of multiple signaling pathways， and the Wnt/β-catenin signaling pathway， as one of the most important pathways in cancer， is involved in the whole process of lung cancer development by regulating the expression of related signaling proteins and genes. In recent years， many studies have confirmed that TCM monomers and TCM compounds can inhibit the epithelial-mesenchymal transition （EMT） process of lung cancer and the activity of lung cancer stem cells （LCSCs） by regulating the Wnt/β-catenin signaling pathway， induce lung cancer cell apoptosis， inhibit the proliferation， invasion and migration of lung cancer cells， and thus play an anti-lung cancer role. In recent years， research in this field has made breakthroughs， but there is a lack of systematic reviews and summaries. Thus， this paper reviewed relevant literature worldwide to analyze and interpret the mechanism of TCM intervention in the Wnt/β-catenin signaling pathway against lung cancer. The TCM monomers targeted to regulate this signaling pathway were summarized in four categories： promoting blood circulation for removing blood stasis， clearing heat and removing dampness， clearing heat and removing toxicity， and awakening the spirit. TCM compounds included Buzhong Yiqitang， Xuefu Zhuyutang， et al. This study aims to provide new ideas for clinical research and drug development for lung cancer.

Gastric cancer （GC） is one of the most common cancers in the world， with hidden symptoms， complex pathogenesis， high morbidity， high mortality， and poor prognosis. As one of the classical apoptosis pathways， mitochondrial apoptosis has been widely described in the apoptosis escape by GC cells. Mitochondrial apoptosis can regulate the proliferation， invasion， and metastasis of GC cells via oxidative stress， cell cycle， mitochondrial membrane potential， mitochondrial translocation and other mechanisms， and it is one of the potential targets of traditional Chinese medicine （TCM） intervention to restore the mitochondrial function in GC. The theory of spleen-mitochondria in correlation explains that spleen deficiency and cancer toxin are the root causes of mitochondrial apoptosis. Accordingly， the TCM treatment should follow the basic principle of invigorating spleen to restore healthy Qi and removing cancer toxin to eliminate the root cause. Mitochondrial apoptosis can be promoted by inhibiting oxidative stress， promoting cell cycle arrest， and reducing mitochondrial membrane potential. This therapy can improve the energy metabolism， restore the mitochondrial structure and function， and prevent the occurrence and development of GC， with mild side effects and low drug resistance. However， the mechanism of mitochondrial apoptosis in GC and the target of TCM intervention in GC have not been systematically reviewed. Therefore， this paper systematically summarized the effects of mitochondrial apoptosis on the occurrence and development of GC and the role of TCM in the treatment of GC by intervening in mitochondrial apoptosis， aiming to provide a theoretical reference for the treatment and further research of GC.

Pulmonary blast injury has become the main type of trauma in modern warfare, characterized by externally mild injuries but internally severe injuries, rapid disease progression, and a high rate of early death. The injury is complicated in clinical practice, often with multiple and compound injuries. Currently, there is a lack of effective protective materials, accurate injury detection instrument and portable monitoring and transportation equipment, standardized clinical treatment guidelines in various medical centers, and evidence-based guidelines at home and abroad, resulting in a high mortality in clinlcal practice. Therefore, the Trauma Branch of Chinese Medical Association and the Editorial Committee of Chinese Journal of Trauma organized military and civilian experts in related fields such as thoracic surgery and traumatic surgery to jointly develop the Clinical treatment guideline for pulmonary blast injury ( version 2023) by combining evidence for effectiveness and clinical first-line treatment experience. This guideline provided 16 recommended opinions surrounding definition, characteristics, pre-hospital diagnosis and treatment, and in-hospital treatment of pulmonary blast injury, hoping to provide a basis for the clinical treatment in hospitals at different levels.

Objective:To compare the efficacy of standardized incision and conventional incision for reduction and internal fixation of multiple rib fracture.Methods:A retrospective cohort study was conducted to analyze the clinical data of 192 patients with multiple rib fracture treated in 909th Hospital of Joint Logistics Support Force (Affiliated Dongnan Hospital of Xianmen University Medical College) from January 2020 to January 2022. There were 101 males and 91 females; aged 32-94 years [(51.5±16.6)years]. The patients underwent open reduction and internal fixation with nickel-titanium shape memory alloy embracer via standard incision such as anterior axillary longitudinal incision (standard incision group, n=96) or conventional incision such as posterolateral incision (conventional incision group, n=96). The incision length, operation time, intraoperative blood loss, number of fixed fractures, indwelling time of closed thoracic drainage tube, postoperative thoracic drainage volume, postoperative spontaneous ambulation time and length of hospital stay were compared in the two groups. The visual analogue scale (VAS) was used to evaluate pain at 1 month after operation. Postoperative complications were recorded. Results:All patients were followed up for 1-16 months [4.0(3.0, 10.5)months]. The operation time, intraoperative blood loss, indwelling time of closed thoracic drainage tube, postoperative thoracic drainage volume, postoperative spontaneous ambulation time, length of hospital stay and VAS at postoperative 1 month in standard incision group [(12.1±1.6)cm, (51.4±13.0)minutes, (191.5±16.8)ml, (2.8±0.6)days, (568.9±109.0)ml, (4.1±0.7)days, (11.4±1.7)days, (2.5±0.7)points] were better than those in conventional incision group [(13.7±1.9)cm, (62.0±8.8)minutes, (248.9±65.4)ml, (4.8±1.1)days, (655.9±121.9)ml, (5.2±0.9)days, (15.3± 1.7)days, (3.5±0.7)points] ( P<0.05 or 0.01). There was no statistical difference in the number of fixed fractures between standard incision group and conventional incision group (5.1±0.8 vs. 5.4±0.9) ( P>0.05). In standard incision group, there were 3 patients with poor wound healing, 5 with pulmonary infection, 3 with atelectasis and 3 with small pleural effusion. In conventional incision group, there were 11 patients with poor wound healing, 9 with pulmonary infection, 7 with atelectasis and 7 with small pleural effusion. The incidence of postoperative complications was 14.6% (14/96) in standard incision group and 35.4% (34/96) in conventional incision group ( P<0.01). Conclusion:For multiple rib fracture, standard incision is superior to conventional incision reduction in shortening the incision length, operation time, indwelling time of drainage tube, postoperative spontaneous ambulation time and length of hospital stay, reducing the intraoperative blood loss and postoperative thoracic drainage volume, alleviating the pain and reducing the postoperative complications.

Objective:To compare the clinical efficacy of extracorporeal membrane oxygenation (ECMO) and ventilation therapy in the treatment of severe blast lung injury.Methods:A retrospective cohort study was conducted to analyze the clinical data of 37 patients with severe blast lung injury admitted to 909th Hospital of Joint Logistics Support Force (Affiliated Dongnan Hospital of Xianmen University Medical College) from January 2000 to December 2021, including 23 males and 14 females; aged 26-50 years [(36.3±11.1)years]. The chest abbreviated injury score (AIS) was 3-5 points. In all, 16 patients were treated with ECMO from January 2017 to December 2021 (ECMO group) and 21 with ventilator from January 2000 to December 2016 (ventilator group). Blood gas analysis indexes [arterial pH, partial pressure of carbon dioxide (PaCO 2), partial pressure of oxygen (PaO 2), blood lactate (Lac)] and hemodynamics indexes [central venous pressure (CVP), cardiac output index (CI), pulmonary arterial systolic pressure (PASP), pulmonary capillary wedge pressure (PAWP)] were compared in the two groups at 30 minutes before treatment and at 2, 4, 6 hours after treatment. The mechanical ventilation time, ICU length of stay, acute physiology and chronic health evaluation II (APACHE II) score and mortality were measured at 7 days after treatment. Results:All patients were followed up for 24-48 months [(33.6±8.2)months]. The blood gas analysis and hemodynamic indexes were significantly improved in the two groups at 2, 4, 6 hours after treatment when compared with those at 30 minutes before treatment (all P<0.05), and the improvements were still statistically significant in ECMO group at 4, 6 hours after treatment when compared with those at 2 hours after treatment (all P<0.05), while not in ventilator group (all P>0.05). There was no significant difference in blood gas analysis indexes or hemodynamic indexes between the two groups at 30 minutes before treatment (all P>0.05). After treatment for 2, 4, 6 hours, blood gas analysis indexes and hemodynamic indexes in ECMO group were statistically different from those in ventilator group (all P<0.05). After treatment for 7 days, the mechanical ventilation time, ICU length of stay, APACHE II score and mortality were (3.2±1.2)days, (5.4±1.3)days, (14.1±3.3)points and 12.5% (2/16) in ECMO group, significantly different from (5.1±1.6)days, (7.6±1.6)days, (10.2±2.6)days and 28.6% (6/21) in ventilator group (all P<0.05). Conclusion:For severe blast lung injury, ECMO can attain rapid and continuous improvement of refractory hypoxemia and dyspnea, shorten the duration of mechanical ventilation and ICU length of stay and reduce the mortality rate when compared with ventilator therapy.
