Objective To explore the potential causal relationship between 91 inflammatory factors and the risk of lung cancer (LC). Methods By extracting related data of inflammatory factors and LC and its subtypes from public databases of Genome-wide Association Studies (GWAS), bidirectional, repeated, multivariable Mendelian randomization (MR) and subgroup MR methods were used for analysis. The inverse variance weighted method was mainly used for causal inference, and a series of sensitivity analyses were applied to verify the strength of the results. Results Higher levels of CD5, interleukin-18 (IL-18), and oncostatin-M (OSM) were causally associated with a lower risk of LC, while nerve growth factor-β (NGF-β) and S100 calcium-binding protein A12 (S100A12) were associated with an increased risk of LC. Subgroup MR analysis results showed that IL-18 had a causal relationship with a reduced risk of lung adenocarcinoma, while NGF-β and S100A12 had a causal relationship with an increased risk of lung adenocarcinoma; CD5 and OSM had a causal relationship with a reduced risk of lung squamous cell carcinoma; NGF-β had a causal relationship with an increased risk of small cell lung cancer. Conclusion Five inflammatory factors, including CD5, IL-18, OSM, NGF-β, and S100A12 have a causal correlation with the risk of LC, providing potential targets for early screening of LC patients and development of therapeutic drugs.

ObjectiveTo investigate the impact of hepatocellular carcinoma (HCC) on the prognosis of patients with liver cirrhosis undergoing emergency endoscopic therapy for esophagogastric variceal bleeding, as well as independent influencing factors for the prognosis of liver cirrhosis patients without HCC after emergency endoscopic therapy for esophagogastric variceal bleeding. MethodsA total of 117 liver cirrhosis patients without HCC and 119 liver cirrhosis patients with HCC who underwent emergency endoscopic therapy for esophagogastric variceal bleeding in Renmin Hospital of Wuhan University from January 2017 to July 2023 were enrolled. Basic information including age and sex was collected from all patients, as well as the presence or absence of chronic diseases such as hypertension, diabetes, and coronary heart disease, the time of emergency endoscopy after admission, and liver function parameters including international normalized ratio, albumin, creatinine, sodium, total bilirubin, alanine aminotransferase, and aspartate aminotransferase (AST). The independent-samples t test was used for comparison of normally distributed continuous variables between two groups, and the Wilcoxon rank-sum test was used for comparison of non-normally distributed continuous variables between two groups; the chi-square test was used for comparison of categorical variables between groups. The covariance analysis and the multivariate logistic regression analysis were used for comparison of outcome variables after control of baseline variables, and the Kaplan-Meier survival curve was plotted for each group. The univariate and multivariate Cox regression analyses were performed for survival time in the non-HCC group to investigate the independent influencing factors for survival time, and then the Kaplan-Meier curve analysis and the log-rank test were performed to validate such independent influencing factors and analyze the independent influencing factors for secondary outcomes. ResultsCompared with the non-HCC group, the HCC group had significantly higher red blood cell transfusion units (6.00[2.00~9.00] vs 4.00[1.75~7.00], Z=-2.050, P=0.040, F=4.869, adjusted P=0.028), a significantly shorter survival time (29.77±16.01 days vs 38.07±11.43 days, t=4.574, P<0.001, F=17.294, adjusted P<0.001), and a significantly higher 5-day rebleeding rate (22.69% vs 6.84%, χ2=11.736, P<0.001, adjusted P=0.021). The Kaplan-Meier curve analysis showed that the risk of 42-day mortality in the HCC group was 3.897 (95% confidence interval [CI]: 2.338 — 6.495, P<0.001) times that in the non-HCC group. The multivariate Cox regression analysis of the non-HCC group showed that the total length of hospital stay (hazard ratio [HR]=0.793, 95%CI: 0.644 — 0.976, P=0.029) was an independent protective factor for 42-day survival. The Kaplan-Meier curve analysis showed that a length of hospital stay of >9 days was beneficial for the prognosis of patients (HR=4.302, 95%CI: 1.439 — 12.870, P=0.037). Blood sodium level (odds ratio [OR]=0.523, 95%CI: 0.289 — 0.945, P=0.032) and MELD-Na score (OR=0.495, 95%CI: 0.257 — 0.954, P=0.036) were independent protective factors against 5-day rebleeding, while AST level was an independent risk factor for 5-day rebleeding (OR=1.023, 95%CI: 1.002 — 1.043, P=0.028) and in-hospital death (OR=1.036, 95%CI: 1.001— 1.073, P=0.045). ConclusionLiver cirrhosis patients with variceal bleeding and HCC tend to have a worse prognosis, and for the non-HCC group, in-hospital mortality rate increases with the increase in AST level. The total length of hospital stay is an independent protective factor for survival time in the non-HCC group, and it is recommended to appropriately prolong the length of hospital stay for such patients.

BACKGROUND:
Asthma is a common chronic inflammatory airway disease and intermittent hypoxia is increasingly recognized as a factor that may impact disease progression. The present study investigated whether intermittent hypoxia (IH) could aggravate asthma by promoting hypoxia-inducible factor-1α (HIF-1α)/nucleotide-binding oligomerization domain (NOD)-like receptor pyrin domain-containing protein 3 (NLRP3)/interleukin (IL)-1β-dependent pyroptosis and the inflammatory response and further elucidated the underlying molecular mechanisms involved.
METHODS:
A total of 49 patients diagnosed with severe bronchial asthma and diagnosed by polysomnography were enrolled at Tongji Hospital, Tongji Medical College of Huazhong University of Science and Technology, between January 2022 and December 2022, and their general data and induced sputum were collected. BEAS-2B cells were treated with IL-13 and subjected to IH. An ovalbumin (OVA)-treated mouse model was also used to assess the effects of chronic intermittent hypoxia (CIH) on asthma. Pyroptosis, the inflammatory response, and related signalling pathways were assessed in vivo and in vitro .
RESULTS:
In this study, as the apnoea and hypopnea index (AHI) increased, the proportion of patients with uncontrolled asthma increased. The proportions of neutrophils and the levels of IL-6, IL-8, HIF-1α and NLRP3 in induced sputum were related to the AHI. NLRP3-mediated pyroptosis, which could be mediated by the HIF-1α signalling pathway, was activated in IL-13 plus IH-treated BEAS-2B cells and in the lungs of OVA/CIH mice. HIF-1α downregulation significantly reduced lung pyroptosis and ameliorated neutrophil inflammation by modulating the NLRP3/IL-1β pathway both in vitro and in vivo . Similarly, pretreatment with LW6, an inhibitor of HIF-1α, effectively blocked the generation of inflammatory cytokines in neutrophils. In addition, administration of the NLRP3 activator nigericin obviously increased lung neutrophil inflammation.
CONCLUSIONS
Obstructive sleep apnoea-hypopnea syndrome (OSAHS) is a risk factor for asthma exacerbation. IH aggravates neutrophil inflammation in asthma via NLRP3/IL-1β-dependent pyroptosis mediated by the HIF-1α signalling pathway, which should be considered a potential therapeutic target for the treatment of asthma with OSAHS.

Objective To investigate the changes of serum cardiac-specific troponin I (cTnI) level in patients after lung transplantation. Methods Clinical data of patients undergoing lung transplantation in our hospital from December 2016 to December 2022 were retrospectively analyzed. The relationship between postoperative serum cTnI level and clinical characteristics were explored. Results Finally 20 patients were collected, including 15 males and 5 females with an average age of (51.65±12.79) years. The serum cTnI level was significantly increased after lung transplantation. The serum cTnI reached the highest level on the first day after transplantation, and significantly decreased from the third day after transplantation. The serum cTnI levels in patients with obstructive pulmonary disease and bilateral lung transplantation were significantly higher than those in patients with restrictive pulmonary disease and unilateral lung transplantation on the day after surgery and on the first day after transplantation. Conclusion Transient myocardial injury can occur after lung transplantation, which is characterized by an abnormal increase in serum cTnI level.

Coronary restenosis is an important cause of poor long-term prognosis in patients with coronary heart disease. Here, we show that lysine methyltransferase SMYD2 expression in the nucleus is significantly elevated in serum- and PDGF-BB-induced vascular smooth muscle cells (VSMCs), and in tissues of carotid artery injury-induced neointimal hyperplasia. Smyd2 overexpression in VSMCs (Smyd2-vTg) facilitates, but treatment with its specific inhibitor LLY-507 or SMYD2 knockdown significantly inhibits VSMC phenotypic switching and carotid artery injury-induced neointima formation in mice. Transcriptome sequencing revealed that SMYD2 knockdown represses the expression of serum response factor (SRF) target genes and that SRF overexpression largely reverses the inhibitory effect of SMYD2 knockdown on VSMC proliferation. HDAC3 directly interacts with and deacetylates SRF, which enhances SRF transcriptional activity in VSMCs. Moreover, SMYD2 promotes HDAC3 expression via tri-methylation of H3K36 at its promoter. RGFP966, a specific inhibitor of HDAC3, not only counteracts the pro-proliferation effect of SMYD2 overexpression on VSMCs, but also inhibits carotid artery injury-induced neointima formation in mice. HDAC3 partially abolishes the inhibitory effect of SMYD2 knockdown on VSMC proliferation in a deacetylase activity-dependent manner. Our results reveal that the SMYD2-HDAC3-SRF axis constitutes a novel and critical epigenetic mechanism that regulates VSMC phenotypic switching and neointimal hyperplasia.

OBJECTIVE:
To establish the dynamic treatment strategy of Chinese medicine (CM) for metastatic colorectal cancer (mCRC) by machine learning algorithm, in order to provide a reference for the selection of CM treatment strategies for mCRC.
METHODS:
From the outpatient cases of mCRC in the Department of Oncology at Xiyuan Hospital, China Academy of Chinese Medical Sciences, 197 cases that met the inclusion criteria were screened. According to different CM intervention strategies, the patients were divided into 3 groups: CM treatment alone, equal emphasis on Chinese and Western medicine treatment (CM combined with local treatment of tumors, oral chemotherapy, or targeted drugs), and CM assisted Western medicine treatment (CM combined with intravenous regimen of Western medicine). The survival time of patients undergoing CM intervention was taken as the final evaluation index. Factors affecting the choice of CM intervention scheme were screened as decision variables. The dynamic CM intervention and treatment strategy for mCRC was explored based on the cost-sensitive classification learning algorithm for survival (CSCLSurv). Patients' survival was estimated using the Kaplan-Meier method, and the survival time of patients who received the model-recommended treatment plan were compared with those who received actual treatment plan.
RESULTS:
Using the survival time of patients undergoing CM intervention as the evaluation index, a dynamic CM intervention therapy strategy for mCRC was established based on CSCLSurv. Different CM intervention strategies for mCRC can be selected according to dynamic decision variables, such as gender, age, Eastern Cooperative Oncology Group score, tumor site, metastatic site, genotyping, and the stage of Western medicine treatment at the patient's first visit. The median survival time of patients who received the model-recommended treatment plan was 35 months, while those who receive the actual treatment plan was 26.0 months (P=0.06).
CONCLUSIONS
The dynamic treatment strategy of CM, based on CSCLSurv for mCRC, plays a certain role in providing clinical hints in CM. It can be further improved in future prospective studies with larger sample sizes.

AIM: To explore the clinical application value of analysis system for ultrasound biomicroscopy(UBM)images of anterior chamber angle(ACA)based on deep learning algorithm.METHODS: A total of 4 196 UBM images were obtained from 675 patients(1 130 eyes)at the Eye Center of Renmin Hospital of Wuhan University from January 2021 to June 2022 were collected to build an image dataset. Using Unet++network to automatically segment ACA tissue, a support vector machine(SVM)algorithm was developed to automatically classify opening and closing of chamber angle, and an algorithm to automatically locate the sclera spur and measure ACA parameters was developed. Furthermore, a total of 631 UBM images of 127 subjects(221 eyes)at Huangshi Aier Eye Hospital and 594 UBM images of 188 subjects(257 eyes)at Zhongnan Hospital of Wuhan University were selected to evaluate the performance of the system under different environments.RESULTS: The accuracy of the analysis system constructed in this study for chamber angle opening and closing was 95.71%. The intra-class correlation coefficient(ICC)values of all ACA angle parameters were greater than 0.960. ICC values of all ACA thickness parameters were greater than 0.884. The accurate measurement of ACA parameters depended in part on the accurate location of the scleral spur.CONCLUSION: The intelligent analysis system constructed in this study can accurately and effectively evaluate ACA images automatically and is a potential screening tool for the rapid identification of ACA structures.

Background In mainland China, patients with neovascular age-related macular degeneration (nAMD) have approximately an 40% prevalence of polypoidal choroidal vasculopathy (PCV). This disease leads to recurrent retinal pigment epithelium detachment (PED), extensive subretinal or vitreous hemorrhages, and severe vision loss. China has introduced various treatment modalities in the past years and gained comprehensive experience in treating PCV.Methods A total of 14 retinal specialists nationwide with expertise in PCV were empaneled to prioritize six questions and address their corresponding outcomes, regarding opinions on inactive PCV, choices of anti-vascular endothelial growth factor (anti-VEGF) monotherapy, photodynamic therapy (PDT) monotherapy or combined therapy, patients with persistent subretinal fluid (SRF) or intraretinal fluid (IRF) after loading dose anti-VEGF, and patients with massive subretinal hemorrhage. An evidence synthesis team conducted systematic reviews, which informed the recommendations that address these questions. This guideline used the GRADE (Grading of Recommendations, Assessment, Development, and Evaluation) approach to assess the certainty of evidence and grade the strengths of recommendations. Results The panel proposed the following six conditional recommendations regarding treatment choices. (1) For patients with inactive PCV, we suggest observation over treatment. (2) For treatment-na?ve PCV patients, we suggest either anti-VEGF monotherapy or combined anti-VEGF and PDT rather than PDT monotherapy. (3) For patients with PCV who plan to initiate combined anti-VEGF and PDT treatment, we suggest later/rescue PDT over initiate PDT. (4) For PCV patients who plan to initiate anti-VEGF monotherapy, we suggest the treat and extend (T&E) regimen rather than the pro re nata (PRN) regimen following three monthly loading doses. (5) For patients with persistent SRF or IRF on optical coherence tomography (OCT) after three monthly anti-VEGF treatments, we suggest proceeding with anti-VEGF treatment rather than observation. (6) For PCV patients with massive subretinal hemorrhage (equal to or more than four optic disc areas) involving the central macula, we suggest surgery (vitrectomy in combination with tissue-plasminogen activator (tPA) intraocular injection and gas tamponade) rather than anti-VEGF monotherapy. Conclusions Six evidence-based recommendations support optimal care for PCV patients' management.

Objective:To evaluate the efficacy of glucocorticoid sinus stents implanted 2 weeks after functional endoscopic sinus surgery(FESS) for the treatment of chronic rhinosinusitis with nasal polyps(CRSwNP). Methods:CRSwNP patients with similar bilateral lesions were randomly divided into two groups, with a stent group of 25 patients and a control group of 24 patients. Patients in the stent group had glucocorticoid sinus stents implanted into the bilateral ethmoid sinuses 2 weeks after FESS, while the control group underwent postoperative debridement only. Follow-up assessments occurred at postoperative weeks 2, 4, 8, and 12. Patients were asked to assess their sensation of nasal symptoms using a 10-point visual analog scale. Efficacy was assessed by endoscopic evaluations. Sinus obstruction, crusting/coagulation, polyp formation, middle turbinate position, adhesions, mucosa epithelialization, and postoperative intervention were assessed as efficacy outcomes. GraphPad Prism 9 was applied for statistical analysis. Results:At 4 and 8 weeks postoperatively, the stent group showed significant improvement in VAS scores of nasal congestion and runny nose compared with the control group(P<0.05). No significant difference was observed in the VAS scores of head and facial stuffiness, loss of smell, or nasal dryness/crusting between the two groups(P>0.05). Compared with the control group, the stent group had a lower rate of polypoid formation at 4, 8, and 12 weeks postoperatively. At postoperative week 12, the rate of mucosal epithelialization in the ethmoid cavity was significantly higher in the stent group. During the follow-up, the frequency of postoperative intervention was significantly lower in the stent group than in the control group(P<0.05). Besides, a lower incidence of middle turbinate lateralization was found in the stent group at 8 and 12 weeks postoperatively. At 8 weeks postoperatively, the stent group had a percentage of adhesion lower than that of the control group(all P<0.05). Conclusion:Implantation of glucocorticoid sinus stents after FESS can maintain sinus cavity patency, improve the inflammatory status of the operative cavity, reduce postoperative interventions, and promote benign regression of the operative cavity.
