Objective To assess the effect of early nutritional intervention on the patients with respiratory diseases at nutritional risk. Methods A total of 130 patients with respiratory disease who were hospitalized in Shanghai Fifth People’s Hospital, Fudan University between May 2023 and December 2024 and had a nutritional risk screening 2002 score ≥3 points. Based on the initiation time of nutritional intervention, patients were divided into an early group (≤5 days, n=65) and a late group (>5 days, n=65). Results In the early group, prealbumin (P-ALB) and retinol-binding protein (RBP) levels were significantly higher (P<0.01), C-reactive protein (CRP), procalcitonin (PCT) levels were significantly lower after intervention (P<0.05). Compared with the late group, the hospital costs were lower and hospital stays were shorter in the early group (P<0.001). Spearman analysis showed ALB, P-ALB, and total protein (TP) were negatively correlated with hospital costs (r=-0.37, -0.20, and-0.22, P<0.05). RBP, ALB, P-ALB, and lymphocyte count (LYM) were negatively correlated with CRP (r=-0.30, -0.26, -0.37, -0.18, P<0.01), RBP, ALB, P-ALB, hemoglobin (HB), and TP were negatively correlated with PCT (r=-0.23,-0.36, -0.40, -0.30, -0.19, P<0.05). Conclusions For patients with respiratory diseases, early nutritional assessment should be underwent, and for patients with nutritional risk screening 2002 score ≥3 points, early nutritional intervention could improve the nutritional status and alleviate inflammatory response, promote recovery, shorten the hospital stays.

ObjectiveTo investigate the mechanism of modified Shenhong Tongluo prescription on cell apoptosis in rats with myocardial ischemia-reperfusion injury (MIRI). MethodSixty Sprague-Dawley (SD) rats were randomly divided into a blank group, a model group, low-, medium-, and high-dose groups of modified Shenhong Tongluo prescription, and a simvastatin group. Except for the blank group, a rat model of MIRI was prepared by ligating the left anterior descending coronary artery. Starting from the first day after successful modeling, the blank group (1.0 mL·kg-1 physiological saline), model group (1.0 mL·kg-1 physiological saline), low-, medium-, and high-dose groups of modified Shenhong Tongluo prescription (1.031, 2.063, and 4.126 g·kg-1 Shenhong Tongluo prescriptiona standard concentrate), and simvastatin group (0.71 mg·kg-1 simvastatin) were orally administered once daily for 2 weeks. Hematoxylin-eosin (HE) staining was used to observe the pathological changes of cardiomyocytes. Enzyme-linked immunosorbent assay (ELISA) was used to detect the levels of serum creatine kinase isoenzyme (CK-MB), interleukin-6 (IL-6), and tumor necrosis factor-α (TNF-α). TdT-mediated dUTP nick-end labeling(TUNEL) staining was used to detect the apoptosis rate of rat cardiomyocytes. Western blot was used to detect the expression levels of apoptosis-related proteins B-cell lymphoma-2 (Bcl-2), Bcl-2-associated X protein (Bax), and caspase-3. ResultCompared with the blank group, in the model group, HE staining showed disturbed arrangement of cardiomyocytes, incomplete fibers, focal necrosis of cardiomyocytes, and inflammatory cell infiltration; serum CK-MB, IL-6, and TNF-α levels were significantly increased (P<0.05); apoptosis rate of cardiomyocytes was significantly increased (P<0.01), with significantly increased expression levels of Bax and Caspase-3 proteins, and significantly decreased Bcl-2 expression (P<0.05). Compared with the model group, the low-, medium-, and high-dose groups of modified Shenhong Tongluo prescription significantly reduced CK-MB, IL-6, and TNF-α levels (P<0.05), significantly downregulated cardiomyocyte apoptosis rate (P<0.05), significantly decreased Bax and Caspase-3 proteins, and significantly increased Bcl-2 expression levels (P<0.01). In the modified Shenhong Tongluo prescription groups, the expression levels of Bax and Caspase-3 proteins significantly decreased with increasing dosage, while the expression level of Bcl-2 significantly increased with increasing dosage of modified Shenhong Tongluo prescription (P<0.05). ConclusionShenhong Tongluo prescription can alleviate myocardial tissue pathological damage and reduce myocardial cell apoptosis, possibly by inhibiting Caspase-3 and Bax expression and promoting Bcl-2 expression.

Cardiomyopathy is a group of heterogeneous myocardial diseases with a variety of specific phenotypes that can lead to cardiovascular death or progressive heart failure in severe cases.Because of the severity and complexity of these diseases,the search for new regulatory mechanisms to prevent and treat cardiomyopathy is particularly urgent.Iron death is a form of programmed cell death that differs from other forms of iron dependence and is characterized by the accumulation of iron-dependent lipid peroxides.Studies have shown that iron death can be involved in the occurrence and progression of cardiomyopathy through different signaling pathways.Therefore,targeted regulation of iron death is a new strategy to prevent cardiomyopathy.In this paper,the mechanism of iron death and its important role in cardiomyopathy were reviewed to find the potential relationship between iron death and cardiomyopathy and provide more ideas for the treatment of various cardiomyopathies in the future.

Objective:To investigate the application effect of production-oriented approach (POA) for consulting ability teaching in general practice standardized residency training.Methods:Eighteen third-year general practice residents in the Second Affiliated Hospital of Harbin Medical University received a special training course on the consulting ability based on POA with the situational simulation teaching from September 2021 to March 2022. The consulting ability of residents was evaluated with Objective Structured Clinical Examination (OSCE) and Leichester Assessment Package (LAP) before and after the training, and the results were compared. Meanwhile, a questionnaire survey and semi-structured interviews were conducted to assess residents′ satisfaction with the course.Results:All 18 resident trainees (11 females and 7 males) aged 25 to 34 (27.3±2.4) years successfully completed the training. Both OSCE scores and LAP scores after the training were significantly higher than those before training (66.25±5.84 vs. 44.44±12.80, t=8.46, P<0.001; 65.78±7.05 vs. 38.33±14.2, t=1.47, P<0.001, respectively). The ability of medical history collection, physical examination, patient management, problem solving, doctor-patient relationship, preventive care and medical record writing were all significantly improved after the training compared with those before training ( t=2.464, 4.278, 8.997, 2.385, 10.35, 5.212, 7.578, all P<0.05). The questionnaire survey showed that all the 18 residents were satisfied with the reasonableness of the teaching content, the class time arrangement, the teaching progress arrangement and the instructors. In the dimension of training effectiveness, 18 participants all believed that the course was helpful to improve their humanistic quality and confidence in reception. In terms of self-promotion, all respondents believed that this course was able to promote their reflection ability and stimulate their learning interest. By coding and analyzing the contents of the semi-structured interviews with the residents, nine main themes were constructed, namely course deficiencies, course characteristics, course advantages, course suggestions, trainees′ deficiencies, trainees′ gains, trainees′ goals, previous teaching deficiencies, and instructor′s role. The results showed that all residents had a high degree of satisfaction with the course, and they thought the course was vivid and interesting and it is able to mobilize the enthusiasm of learning, promote learner to reflect. The residents also suggested to increase the teaching hours and to enrich teaching cases. Conclusion:The consulting ability training of general practice based on POA can effectively improve consulting ability, stimulate learning interest and improve independent learning ability of residents, which gains recognition from both faculty and trainees.

OBJECTIVE
To explore the mechanism of action of epigallocatechin-3-gallate(EGCG) in inhibiting laryngeal cancer cells.
METHODS
The expression of epidermal growth factor receptor(EGFR) in laryngeal cancer cell lines AMC-HN-8, TU686 and TU212 was detected by Western blotting, and the inhibitory effects of cetuximab and EGCG on three laryngeal cancer cells were detected by CCK-8 assay. A lentiviral vector containing EGFR promoter and Luc reporter gene was constructed to generate a TU686-EGFR-Luc cell line that could steadily express Luc activity. Luciferase assay was performed to evaluate the effect of EGCG on the transcription activity of EGFR promoter. Cell cycle and apoptosis of EGCG-treated laryngeal carcinoma cells were analyzed by flow cytometry, and changes of the levels of EGFR and downstream ERK1/2, cell cycle-associated proteins P53 and P27, apoptosis-associated proteins BCL2 and PART, and autophagy marker LC3A/B were further examined.
RESULTS
The laryngeal carcinoma cell lines were insensitive to cetuximab but could be effectively suppressed by EGCG. EGCG effectively inhibited the transcription activity of EGFR promoter. Treatment of TU686 cells at sub-IC50 dose EGCG resulted in significant cell cycle arrest at S phase with partial apoptosis. Significant inhibition of expression and activation of EGFR and downstream signaling pathway were observed.
CONCLUSION
EGCG can effectively downregulate EGFR and suppress laryngeal carcinoma cells, further investigation on in vivo effect and mechanisms are anticipated.

Objective:
To elucidate the biological basis of the heart qi deficiency (HQD) pattern, an in-depth understanding of which is essential for improving clinical herbal therapy.
Methods:
We predicted and characterized HQD pattern genes using the new strategy, TCM-HIN2Vec, which involves heterogeneous network embedding and transcriptomic experiments. First, a heterogeneous network of traditional Chinese medicine (TCM) patterns was constructed using public databases. Next, we predicted HQD pattern genes using a heterogeneous network-embedding algorithm. We then analyzed the functional characteristics of HQD pattern genes using gene enrichment analysis and examined gene expression levels using RNA-seq. Finally, we identified TCM herbs that demonstrated enriched interactions with HQD pattern genes via herbal enrichment analysis.
Results:
Our TCM-HIN2Vec strategy revealed that candidate genes associated with HQD pattern were significantly enriched in energy metabolism, signal transduction pathways, and immune processes. Moreover, we found that these candidate genes were significantly differentially expressed in the transcriptional profile of mice model with heart failure with a qi deficiency pattern. Furthermore, herbal enrichment analysis identified TCM herbs that demonstrated enriched interactions with the top 10 candidate genes and could potentially serve as drug candidates for treating HQD.
Conclusion
Our results suggested that TCM-HIN2Vec is capable of not only accurately identifying HQD pattern genes, but also deciphering the basis of HQD pattern. Furthermore our finding indicated that TCM-HIN2Vec may be further expanded to develop other patterns, leading to a new approach aimed at elucidating general TCM patterns and developing precision medicine.

Traumatic supraorbital fissure syndrome (TSOFS) is a symptom complex caused by nerve entrapment in the supraorbital fissure after skull base trauma. If the compressed cranial nerve in the supraorbital fissure is not decompressed surgically, ptosis, diplopia and eye movement disorder may exist for a long time and seriously affect the patients′ quality of life. Since its overall incidence is not high, it is not familiarized with the majority of neurosurgeons and some TSOFS may be complicated with skull base vascular injury. If the supraorbital fissure surgery is performed without treatment of vascular injury, it may cause massive hemorrhage, and disability and even life-threatening in severe cases. At present, there is no consensus or guideline on the diagnosis and treatment of TSOFS that can be referred to both domestically and internationally. To improve the understanding of TSOFS among clinical physicians and establish standardized diagnosis and treatment plans, the Skull Base Trauma Group of the Neurorepair Professional Committee of the Chinese Medical Doctor Association, Neurotrauma Group of the Neurosurgery Branch of the Chinese Medical Association, Neurotrauma Group of the Traumatology Branch of the Chinese Medical Association, and Editorial Committee of Chinese Journal of Trauma organized relevant experts to formulate Chinese expert consensus on the diagnosis and treatment of traumatic supraorbital fissure syndrome ( version 2024) based on evidence of evidence-based medicine and clinical experience of diagnosis and treatment. This consensus puts forward 12 recommendations on the diagnosis, classification, treatment, efficacy evaluation and follow-up of TSOFS, aiming to provide references for neurosurgeons from hospitals of all levels to standardize the diagnosis and treatment of TSOFS.
