The TNM staging of lung cancer which is now widely used in clinic was formally proposed in 1997. It has played quite an important role in directing the diagnosis and treatment of lung cancer as well as the clinical research in the past decade. However, at the same time, there are some insufficiencies which are emerging gradually. By collecting the clinical information from 100 869 patients, in 2007, International Association for the Study of Lung Cancer(IASLC) made a deep analysis on the relativity between TNM staging and prognosis, and put forward the suggestions to revise the Seventh Edition of the TNM staging of lung cancer: (1) According to the size of tumor, the primary T staging is divide into T1a (the maximum tumor diameter≤2 cm), T1b (3 cm≥the maximum tumor diameter＞2 cm), T2a (5 cm≥the maximum tumor diameter＞3 cm) and T2b (7 cm≥the maximum tumor diameter＞5 cm); (2) T 2c (the maximum tumor diameter gt;7 cm) and additional nodules in the same lobe are classified as T3, while nodules in the ipsilateral nonprimary lobe are classified as T4;(3) Cancerous hydrothorax, pericardial effusion and the additional nodules in the contralateral lung are classified as M1a, while the extrapulmonary metastases are classified as M1b. It is believed that the new revised edition will has higher international authority and identification degree, and it will play a more meticulous and accurate guiding role in the treatment of lung cancer and its predicting prognosis in the future. At the same time, it will provide a new starting point to the research of lung cancer.
ObjectivesTo systematically review the association between pepper consumption and risk of gastric cancer.MethodsPubMed, EMbase, Web of Science, The Cochrane Library, WanFang Data, VIP and CNKI databases were electronically searched to collect epidemiological studies of evaluating the association between pepper consumption and the risk of gastric cancer from inception to April, 2017. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies, then, meta-analysis was performed by using Stata 12.0 software.ResultsA total of 18 studies involving 17 case-control studies and 1 cohort study with 13 142 participants were included. The studies were divided into quantitative group and non-quantitative group. The results of meta-analysis showed that: ① In quantitative group, medium to heavy pepper consumption was the risk factor of gastric cancer (OR=1.55, 95%CI 1.13 to 2.14, P=0.008). Whereas there was no significant association between low pepper consumption and the risk of gastric cancer (OR=0.63, 95%CI 0.26 to 1.50, P=0.297). ② In the non-quantitative group, pepper consumption was the risk factor of gastric cancer (OR=1.37, 95%CI 1.09 to 1.74, P=0.008). ③ Subgroup analysis results showed that medium to heavy pepper consumption in Asian population had significant association with gastric cancer (OR=2.24, 95%CI 1.88 to 2.67, P=0.005), however, there was no significant association between low pepper consumption and the risk of gastric cancer (OR=0.62, 95%CI 0.33 to 1.18, P=0.144).ConclusionsThe association between pepper consumption and risk of gastric cancer remains unclear, medium to heavy pepper consumption may be related to the risk of gastric cancer, especially in Asian population.
In the American Heart Association’s Scientific Sessions 2021, the results of six clinical trials related to cardiovascular surgery were revealed. The PALACS trial demonstrated that posterior left pericardiotomy during open heart surgery was associated with a significant reduction in postoperative atrial fibrillation; the EPICCURE study found that injection of mRNA encoding vascular endothelial growth factor (VEGF-A mRNA) directly into the myocardium of patients undergoing elective coronary artery bypass grafting (CABG) improved patients’ heart function; the VEST trial once again proved the safety and potential value of external stent for vein graft. This article will interpret the above-mentioned three studies.
ObjectiveTo explore the association between free fatty acid (FFA) and extent of severity of acute coronary syndrome (ACS). MethodsWe analyzed the clinical data of 93 ACS in-patients treated between July 2014 and May 2015, including 35 with acute ST-elevation myocardial infarction (STEMI), 34 with acute non STEMI (NSTEMI), and 24 with unstable angina (UA). Another 29 in-patients during the same period without coronary heart disease and heart failure and with normal results of electrocardiogram and myocardial damage markers were selected as the control. The statistical analysis of FFA collected within 24 hours after admission was conducted. ResultsThe FFA in the ACS group[(1.08±0.41) mmol/L] was significantly higher than that in control group[(0.51±0.15) mmol/L] (P < 0.01). The FFA in patients with STEMI, NSTEMI, and UA in ACS group was (1.32±0.38), (1.12±0.35, and (0.67±0.10) mmol/L, respectively; the FFA in STEMI and NSTEMI patients was much higher than that in the UA patients (P < 0.05), and the difference between STEMI and NSTEMI patients was not significant (P > 0.05). There were 58 NSTEMI and UA patients evaluated by Grace risk score, in whom 30 had Grace score≥140 with the FFA of (1.12±0.37) mmol/L and 28 had < 140 with the FFA of (0.73±0.17) mmol/L; the difference was significant (P < 0.05). There were 35 STEMI patients evaluated by Killip grade, in whom 16 were Killip I-II with the FFA of (1.17±0.37) mmol/L, and 19 were Killip III-IV with the FFA of (1.45±0.35) mmol/L; the difference was significant (P < 0.05). ConclusionElevated plasma FFA could be associated with ischemic risk and extent of severity of ACS.
In October 2020, the American Heart Association issued the 2020 edition of guidelines for cardiopulmonary resuscitation and cardiovascular first aid, which comprehensively revised cardiopulmonary resuscitation and emergency cardiovascular care guidelines related to adults, children, newborns, resuscitation education science and treatment system. According to the latest edition of International Liaison Committee on Resuscitation’s classes of recommendation and levels of evidence, relevant suggestions are put forward. This article interprets the main updated and revised content, including children’s basic and advanced life support and neonatal resuscitation, in order to better guide emergency personnel and improve the quality of cardiopulmonary resuscitation and cardiovascular first aid.
With the publication of a vast amount of clinical research on hepatocellular carcinoma (HCC), the American Association for the Study of Liver Diseases (AASLD), the National Comprehensive Cancer Network (NCCN), the American Society of Clinical Oncology (ASCO), and the National Health Commission of China have all updated their diagnostic and treatment guidelines for HCC. There are no differences in the definition of HCC risk populations among the AASLD 2023, NCCN 2024, and China Liver Cancer Staging and Treatment Guideline (CNLC) 2024. Notably, CNLC 2024 has updated its guidance on high-risk factors and prospective surveillance for HCC based on the characteristics of HCC patients in China. The four guidelines have seen significant updates in the areas of neoadjuvant and adjuvant therapies, local treatments, and systemic treatments for HCC. CNLC 2024 refines the indications for local treatment, improves systemic treatment, and introduces new first-line therapy, including camrelizumab combined with rivoceranib or tislelizumab. The second-line therapy nivolumab plus ipilimumab for advanced HCC are recommended by AASLD 2023, NCCN 2024, and ASCO 2024, which may become a new first-line therapeutic option for patients with advanced HCC. We compare and interpret these four guidelines in this paper.
ObjectiveTo analyze the association between the acute exacerbation of chronic obstructive pulmonary disease (AECOPD) (syndrome of phlegm-heat obstructing lung) and clinical indicators related to COPD. MethodAECOPD in-patients and out-patients were enrolled from the Third People's Hospital of Chengdu from January 2013 to January 2014. The patients were grouped to Tanre Syndrome and non-Tanre Syndrome according to their clinical symptoms, signs and tongue, pulse. All patients underwent the following tests including routine blood test, erythrocyte sedimentation rate, lung function, blood gas analysis, C-reaction protein (CRP), procalcitonin (PCT) and other clinically relevant indicators. The association between AECOPD and clinically relevant indicators were analyzed by using SPSS 19.0 software. ResultsA total of 194 AECOPD patients were included, of which 88 patients were syndrome of phlegm-heat obstructing lung and 106 were non syndrome of phlegm-heat obstructing lung according to the traditional Chinese medicine (TCM) classifications. The results of single factor analysis showed that age (Z=-4.848, P=0.000) and course of disease (Z=-2.455, P=0.014) were associated with syndrome of phlegm-heat obstructing lung. While further logistic regression analysis showed that age (r=0.090, P=0.000) and the level of CRP (r=-0.008, P=0.000) were associated with syndrome of phlegm-heat obstructing lung. ConclusionSyndrome of phlegm-heat obstructing lung is the major clinical TCM syndrome of AECOPD. Syndrome of phlegm-heat obstructing lung is associated with age and level of CRP.
Objective To reveal the association between the single nucleotide polymorphism (SNP) of v-maf musculoaponeurotic fibrosarcoma oncogene homolog B (MAFB) gene rs17820943 locus and non-syndromic cleft l ip with or without cleft palate (NSCL/P) in the southern Chinese Han population. Methods Genotyping of MAFB gene rs17820943 polymorphism was carried out in 300 patients with NSCL/P, 354 normal controls, and an additional 168 case-parent trios with matrix-assisted laser desorption/ionisation time-of-fl ight (MALDI-TOF) mass spectrometry. Then based on the genotypingresults, both a case-control association study and a case-parent trio association study were performed. Results Significant differences were found in the allele and genotype frequencies of rs17820943 locus between case and control groups (Pallele=0.001 and Pgenotype=0.002, respectively). To be specific, the odds radio (OR) values and 95% confidence interval (95%CI) of allele T (frequencies of cases ∶ controls = 0.358 ∶ 0.448) and genotype TT (frequencies of cases ∶ controls = 0.110 ∶ 0.195) were ORT = 0.69 (95%CI: 0.55-0.86) and ORTT = 0.43 (95%CI: 0.26-0.70), respectively. Subsequent case-parent trio analysis also indicated an association between MAFB rs17820943 variant and the risk of NSCL/P (ORT vs. C = 0.55, 95%CI: 0.41-0.75, P value of transmission disequilibrium test was 0.000). Conclusion Polymorphism of MAFB gene rs17820943 locus is associated with NSCL/P in the southern Chinese Han population; MAFB rs17820943 variant may be a susceptible gene of NSCL/P.
