ObjectiveTo explore the therapeutic effect of Xuebijing injection (XBJ) on severe acute pancreatitis induced acute lung injury (SAP-ALI) by regulating formyl peptide receptors (FPRs)/nucleotide-binding oligomerization domain-like receptor 3 (NLRP3) inflammatory pathway. MethodsSixty rats were randomly divided into a sham group, a SAP-ALI model group, low-, medium-, and high-dose XBJ groups (4, 8, and 12 mL·kg-1), and a positive drug (BOC2, 0.2 mg·kg-1) group. For the sham group, the pancreas of rats was only gently flipped after laparotomy, and then the abdomen was closed, while for the remaining five groups, SAP-ALI rat models were established by retrograde injection of 5% sodium taurocholate (Na-Tc) via the biliopancreatic duct. XBJ and BOC2 were administered via intraperitoneal injection once daily for 3 d prior to modeling and 0.5 h after modeling. Blood was collected from the abdominal aorta 6 h after the completion of modeling, and the expression of interleukin (IL)-1β, IL-6, and tumor necrosis factor-α (TNF-α) in plasma was measured by enzyme-linked immunosorbent assay (ELISA). The amount of ascites was measured, and the dry-wet weight ratios of pancreatic and lung tissue were determined. Pancreatic and lung tissue was taken for hematoxylin-eosin (HE) staining to observe pathological changes and then scored. The protein expression levels of FPR1, FPR2, and NLRP3 in lung tissue were detected by the immunohistochemical method. Western blot was used to detect the expression of FPR1, FPR2, and NLRP3 in lung tissue. Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) was used to detect the mRNA expression of FPR1, FPR2, and NLRP3 in lung tissue. ResultsCompared with the sham group, the SAP-ALI model group showed significantly decreased dry-wet weight ratio of lung tissue (P<0.01), serious pathological changes of lung tissue, a significantly increased pathological score (P<0.01), and significantly increased protein and mRNA expression levels of FPR1, FPR2, and NLRP3 in lung tissue (P<0.01). After BOC2 intervention, the above detection indicators were significantly reversed (P<0.01). After treatment with XBJ, the groups of different XBJ doses achieved results consistent with BOC2 intervention. ConclusionXBJ can effectively improve the inflammatory response of the lungs in SAP-ALI rats and reduce damage. The mechanism may be related to inhibiting the expression of FPRs and NLRP3 in lung tissue, which thereby reduces IL-1β and simultaneously antagonize the release of inflammatory factors IL-6 and TNF-α.

Viral pneumonia is an infectious disease caused by virus invading the lung parenchyma and interstitial tissue and causing lung inflammation, with the incidence rising year by year. Traditional Chinese medicine (TCM) can treat viral pneumonia in a multi-component, multi-target, and holistic manner by targeting the core pathogenesis of pneumonia caused by different respiratory viruses, demonstrating minimal side effects and significant advantages. According to the theory of healthy Qi and pathogenic Qi in TCM, the struggle between healthy Qi and pathogenic Qi and the imbalance between immunity and inflammation run through the entire process of viral pneumonia, and the immunity-inflammation status at different stages of the disease reflects different relationships between healthy Qi and pathogenic Qi. Immune dysfunction leads to the deficiency of healthy Qi, causing viral infections. The struggle between healthy Qi and pathogenic Qi causes immunity-inflammation imbalance, leading to the onset of viral pneumonia. Inflammatory damage causes persistent accumulation of phlegm and stasis, leading to the progression of viral pneumonia. The cytokine storm causes immunodepletion, leading to the excess of pathogenic Qi and diminution of healthy Qi and the deterioration of viral pneumonia. After the recovery from viral pneumonia, there is a long-term imbalance between immunity and micro-inflammation, which results in healthy Qi deficiency and pathogenic Qi lingering. Healthy Qi deficiency and pathogenic Qi excess act as common core causes of pneumonia caused by different respiratory viruses. Clinical treatment should emphasize both replenishing healthy Qi and eliminating pathogenic Qi, helping to restore the balance between healthy Qi and pathogenic Qi as well as between immunity and inflammation, thus promoting the recovery of patients from viral pneumonia. According to the TCM theory of healthy Qi and pathogenic Qi, this article summarizes the immunity-inflammation mechanisms at different stages of viral pneumonia, and explores the application of the method of replenishing healthy Qi and eliminating pathogenic Qi in viral pneumonia. The aim is to probe into the scientific connotation of the TCM theory of healthy Qi and pathogenic Qi in viral pneumonia and provide ideas for the clinical application of the method of replenishing healthy Qi and eliminating pathogenic Qi to assist in the treatment of viral pneumonia.

ObjectiveThis study aims to enhance of the farnesyl pyrophosphate(FPP) pool in Saccharomyces cerevisiae by heterologously expressing different farnesyl diphosphate synthases(FPSs) from various plants, thereby increasing the production of terpenoid compounds by the engineered yeast. MethodsRNA from mixed samples of roots, stems, and leaves of seven plants including Arabidopsis thaliana, Rosa rugosa, Artemisia annua, Centella asiatica, Humulus lupulus, Medicago sativa, and Panax ginseng was extracted by column chromatography and reverse transcribed into the first strand of complementary DNA(cDNA), and based on the transcriptome data of the seven species of plants, sequence-specific primers were designed for CaFPS, RrFPS, MsFPS, HiFPS, PgFPS, AtFPS, and AaFPS, the full-length of the genes was cloned, and the genes were analyzed for bioinformatics in order to construct a pESC yeast shuttle vector. These seven plant-derived FPSs were further heterologously expressed in the previous constructed β-elemene-producing yeast, and the yield of β-elemene was indicated for their catalytic acivities. ResultsThe coding sequences of CaFPS, RrFPS, MsFPS, HiFPS, PgFPS, AtFPS, and AaFPS were all of 1 021 bp in length and encoding 301 amino acids, all of which were similarly related to the endogenous FPS-encoding gene(ERG20) in S. cerevisiae. After heterologous expression, RrFPS was identified as the most effective in catalyzing the synthesis of FPP from isopentenyl pyrophosphate(IPP) and dimethylallyl pyrophosphate(DMAPP). Compared to the control strains, the RrFPS overexpressed yeast strains YB-1-Rr and YB-3-Rr increased the production of β-elemene by 231.25% and 189.3%, respectively. ConclusionBy comparing the functions of FPS-encoding genes from seven different plant sources, it is determined that the protein encoded by the RrFPS from R. rugosa has the best catalytic ability, which can provide key genetic elements for the construction of engineered yeast strain constructs with high terpenoid production.

ObjectiveThe research focuses on developing modeling and evaluation methodologies for an animal model exhibiting spleen deficiency and dampness excess syndrome, with the aim of standardizing such animal models for future reference. MethodsBy conducting a literature search on animal models of spleen deficiency and dampness excess syndrome, relevant publications meeting inclusion and exclusion criteria will be identified based on publication date, data source, types of diseases involved, animal characteristics, modeling methods, modeling duration, macroscopic syndrome assessment indicators, macroscopic quantification indicators, laboratory testing parameters, intervention approaches, positive controls and application context. A database will be established to facilitate the extraction of this information for quantitative analysis, statistical evaluation, and visual representation. ResultsA total of 137 literature articles meeting the standards have been included in the research. The primary animal species used in animal models of spleen deficiency and dampness excess are SD rats. Modeling methods include single-factor, dual-factor composite, and triple-factor composite methods, with various models widely applied in validation of pharmacological effects and mechanistic explorations. Evaluation indices of animal models for spleen deficiency and dampness excess primarily consist of macroscopic syndrome evaluation indicators and macroscopic quantitative indicators. Laboratory testing indicators are mostly related to research areas such as fluid metabolism and gastrointestinal function. The most commonly studied herbal formulas currently include Shenling Baizhu San and Pingwei San, with natural recovery and the use of the western medicine metronidazole as the most frequently used positive controls. ConclusionThe application of animal models for spleen deficiency and dampness excess is gradually increasing, with various modeling methods already simulating the typical characteristics of this syndrome pattern. However, there are still many areas that are worth contemplating and improving. This study aims to provide reference and ideas for the standardization of symptom names in animal models of spleen deficiency and dampness excess, as well as for the improvement of model construction and evaluation systems.

OBJECTIVE To explore the effect and potential mechanism of the compatibility of Astragali Radix-Puerariae Lobatae Radix on ferroptosis of liver cells in type 2 diabetes mellitus (T2DM) insulin resistance (IR) rats. METHODS Sixty male SD rats were randomly divided into control group (12 rats) and modeling group (48 rats). The modeling group was fed with a high- fat diet for 4 consecutive weeks and then given a one-time tail vein injection of 1% streptozotocin to establish T2DM IR model. The model rats were randomly divided into model group, the compatibility of Astragali Radix-Puerariae Lobatae Radix group [QG group, 4.05 g/(kg·d), intragastric administration], ferroptosis inhibitor ferrostatin-1 group [Fer-1 group, 5 mg/kg by intraperitoneal injection, once every other day], the compatibility of Astragali Radix-Puerariae Lobatae Radix+ferroptosis inducer erastin group [QG+erastin group, 4.05 g/(kg·d) by intragastric administration+erastin 10 mg/(kg·d), intraperitoneal injection]. After 4 weeks of intervention, serum fasting blood glucose (FBG) and fasting insulin (FINS) were measured in each group of rats, and homeostasis model assessment of insulin resistance (HOMA-IR) and the natural logarithm of insulin action index(IAI) were calculated; the serum levels of total cholesterol (TC), triglyceride (TG), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), aspartate transaminase (AST) and alanine transaminase (ALT), Fe2+ and Fe content, glutathione (GSH), malondialdehyde (MDA) and superoxide dismutase (SOD) levels, NADP+/NADPH ratio and reactive oxygen species (ROS) were determined. The pathological morphology of its liver tissue was observed; the protein expressions of glutathione peroxidase 4 (GPX4), ferritin heavy chain 1 (FTH1), long-chain acyl-CoA synthetase 3 (ACSL3), ACSL4, ferritin mitochondrial (FTMT), and cystine/glutamate anti-porter (xCT) in the liver tissue of rats were detected. RESULTS Compared with control group, the liver cells in the model group of rats showed disordered arrangement, swelling, deepened nuclear staining, and more infiltration of inflammatory cells, as well as a large number of hepatocyte vacuoles and steatosis; FBG (after medication), the levels of TC, TG, LDL-C, AST, ALT, FINS, MDA and ROS, HOMA-IR, Fe2+ and Fe content, NADP+/NADPH ratio and protein expression of ACSL4 were significantly increased or up-regulated, while the levels of HDL-C, GSH and SOD, IAI, protein expressions of GPX4, FTH1, ACSL3, FTMT and xCT were significantly reduced or down-regulated (P<0.01). Compared with the model group, both QG group and Fer-1 group showed varying degrees of improvement in pathological damage of liver tissue and the levels of the above indicators, the differences in the changes of most indicators were statistically significant (P<0.01 or P<0.05). Compared with QG group, the improvement of the above indexes of QG+erastin group had been reversed significantly (P<0.01). CONCLUSIONS The compatibility decoction of Astragali Radix-Puerariae Lobatae Radix can reduce the level of FBG in T2DM IR rats, and alleviate IR degree, ion overload and pathological damage of liver tissue. The above effects are related to the inhibition of ferroptosis.

OBJECTIVE To explore the clinical features, diagnosis, treatment and management measures of multiple immune- related adverse event (irAE) after toripalimab treatment, in order to provide reference for the clinical management of similar cases. METHODS A retrospective analysis was conducted on a post-operative bladder cancer patient who developed various irAEs after toripalimab treatment. The patient’s medical history, laboratory tests, imaging studies, treatment course and outcomes were detailed. The Naranjo scale was used to assess the relationship between the irAEs and toripalimab. RESULTS The patient developed irAEs after receiving toripalimab, such as immune-related myocarditis, liver dysfunction, and myasthenia. According to the Naranjo scale evaluation, it was assessed that these adverse events were related to the administration of toripalimab. After high- dose corticosteroid pulse therapy and immunoglobulin immunomodulation, the patient’s symptoms were effectively relieved, with a improved trend in various physiological indicators and significant improvement in the degree of system/organ damage. CONCLUSIONS Toripalimab may lead to multiple irAEs, including immune-related myocarditis, liver injury, and myasthenia. Early recognition, timely diagnosis, and appropriate treatment of irAE are crucial for improving patient’s prognosis.

Traditional Chinese medicine (TCM) therapy has unique clinical advantages in the treatment of atrial fibrillation, mainly reflected in five aspects, improving quality of life, enabling early diagnosis and treatment, promoting cardiac rehabilitation, making up for the limitations of Western medicine, and improving the success rate of catheter ablation. However, there is insufficient evidence in current clinical research. Based on the current status of TCM research in the treatment of atrial fibrillation, it is suggested that future studies should focus on standardized research on syndrome differentiation and classification. This can be achieved through clinical epidemiological surveys, expert consensus, and other methods to establish a unified syndrome differentiation and classification standard for atrial fibrillation. Clinical efficacy evaluation indicators should be standardized, and core outcome measures for clinical research on TCM treatment of atrial fibrillation should be developed through systematic reviews, patient interviews, and other methods. Additionally, clinical research design, implementation, and data management should be improved. By leveraging modern information technologies such as artificial intelligence, the scientific and standardized nature of TCM intervention research on atrial fibrillation can be enhanced, ultimately improving the quality of research.

Methods:
Data of the incidence and mortality of prostate cancer in Ningbo City from 2011 to 2023 were collected through Ningbo Chronic Disease Collaborative Management System. The incidence and mortality of prostate cancer were calculated and standardized by the data from the sixth national population census in 2010 and the Segi's world standard population in 1960. The trends in incidence and mortality of prostate cancer were evaluated using average annual percent change (AAPC).
Results:
A total of 15 411 cases of prostate cancer were reported in Ningbo City from 2011 to 2023, and the crude incidence, Chinese-standardized incidence and world-standardized incidence were 39.62/105, 22.18/105 and 16.49/105, respectively, showing upward trends (AAPC=14.782%, 10.390% and 10.608%, all P<0.05). The Chinese-standardized incidence of prostate cancer was higher in urban areas than in rural areas, and both showed upward trends (25.14/105 vs. 19.44/105; AAPC=9.057% and 14.272%, both P<0.05). The crude incidence of prostate cancer in the groups aged 50-<60 years, 60-<70 years, 70-<80 years and ≥80 years showed upward trends (AAPC=11.657%, 14.031%, 10.734% and 5.300%, all P<0.05). A total of 3 739 deaths were reported, and the crude mortality, Chinese-standardized mortality and world-standardized mortality were 9.66/105, 5.23/105 and 3.71/105, respectively, showing upward trends (AAPC=8.458%, 3.620% and 3.602%, all P<0.05). The Chinese-standardized mortality of prostate cancer was higher in urban areas than in rural areas, and both showed upward trends (5.35/105 vs. 5.13/105; AAPC=3.183% and 3.962%, both P<0.05). The crude mortality of prostate cancer the groups ageds ≥80 years showed an upward trend (AAPC=7.482%, P<0.05).
Conclusions
From 2011 to 2023, the incidence and mortality of prostate cancer in Ningbo City showed upward trends. Special attention should be paid to urban residents, and prostate cancer screening should be strengthened among males aged 50 years and older.

After continuous development and improvement, lung transplantation has become the preferred means to treat a variety of benign end-stage lung diseases. However, the field of lung transplantation still faces many challenges, including shortage of donor resources, preservation and maintenance of donor lungs, and postoperative complications. Lung tissue samples removed after lung transplantation are excellent clinical resources for the study of benign end-stage lung disease and perioperative complications of lung transplantation. However, at present, the collection, storage and utilization of tissue samples after lung transplantation are limited to a single study, and unified technical specifications have not been formed. Based on the construction plan of the biobank for lung transplantation in the First Affiliated Hospital of Xi'an Jiaotong University, this study reviewed the practical experience in the collection, storage and utilization of lung transplant tissue samples in the aspects of ethical review, staffing, collection process, storage method, quality control and efficient utilization, in order to provide references for lung transplant related research.
