Colorectal cancer(CRC) is one of the most common malignant tumors worldwide, primarily originating from recurrent inflammatory bowel disease(IBD). Therefore, blocking the inflammation-cancer transformation in the colon has become a focus in the early prevention and treatment of CRC. The inflammation-cancer transformation in the colon involves multiple types of cells and complex pathological processes, including inflammatory responses and tumorigenesis. In this complex pathological process, immune cells(including non-specific and specific immune cells) and non-immune cells(such as tumor cells and fibroblasts) interact with each other, collectively promoting the progression of the disease. In traditional Chinese medicine(TCM), inflammation-cancer transformation in the colon belongs to the categories of dysentery and diarrhea, with the main pathogenesis being cold and heat in complexity. This paper first elaborates on the complex molecular mechanisms involved in the inflammation-cancer transformation process in the colon from the perspectives of inflammation, cancer, and their mutual influences. Subsequently, by comparing the pathogenic characteristics and clinical manifestations between inflammation-cancer transformation and the TCM pathogenesis of cold and heat in complexity, this paper explores the intrinsic connections between the two. Furthermore, based on the correlation between inflammation-cancer transformation in the colon and the TCM pathogenesis, this paper delves into the importance of the interaction between inflammation and cancer. Finally, it summarizes and discusses the clinical and basic research progress in the TCM intervention in the inflammation-cancer transformation process, providing a theoretical basis and treatment strategy for the treatment of CRC with integrated traditional Chinese and Western medicine.

Objective To investigate the CT and MRI findings of different types of small round cell tumor(SRCT)in the nasal cavity and sinuses.Methods A retrospective analysis was conducted on the imaging data and clinical data of 35 SRCT patients confirmed by pathology.Thirty-one SRCT patients underwent CT examination,and 19 SRCT patients underwent MRI examination.Results There were 20 cases of tumors that invaded the nasal cavity and 19 cases involved the sinuses,including 11 cases of the maxillary sinus,7 cases of the ethmoid sinus,2 cases of the sphenoid sinus,and 1 case of the frontal sinus.CT findings of SRCT were all soft tissue masses.Lymphoma was relatively homogeneous with mild bone destruction,and usually involved nasal vestibular skin.Rhabdomyosarcoma(embryonic type)happened at an early age and easily caused bone destruction and metastasis.Melanoma generally occurred in the nasal septum and nasal cavity,which was prone to bleeding.Small cell neuroendocrine carcinoma was heterogeneous,with moderate to significant enhancement,bone absorption and destruction were often noticed.The MRI manifestations of SRCT were equal or long signal on T1WI,high signal on T2WI,and significant diffusion limitation on diffusion weighted imaging(DWI)and apparent diffusion coefficient(ADC)except for melanoma.On contrast-enhanced images,lymphoma showed mild to moderate enhancement,rhabdomyosarcoma showed typical"grape sign",and small cell neuroendocrine carcinoma showed"sieve"and"map-like"obvious enhancement.Typical melanoma showed a high signal on T1WI and a low signal on T2WI and usually caused bleeding.The MRI findings were related to the presence of melanoma and hemorrhage within the lesion.Conclusion SRCT of the nasal cavity and sinuses have a high degree of malignancy and poor prognosis,CT and MRI have many similar manifestations.Combining clinical data,bone destruction,MRI enhancement,and DWI sequence can effectively distinguish different types of SRCT,as well as squamous cell carcinoma of the nasal cavity and sinuses and adenoid cystic carcinoma.

Objectve:To observe the change of functional connectivity(FC)characteristic and its correlation with cognitive flexibility in type 2 diabetes mellites(T2DM)patients with cognitive flexibility decreased.Methods:A retro-spective analysis was performed in 24 T2DM patients with cognitive flexibility decreased(T2DM+CD),34 T2DM pa-tients without cognitive flexibility decreased(T2DM-CD)and 31 healthy controls(HC).Wisconsin Card Sorting Test(WCST)and the Stroop Color Word Test(Stroop)were respectively used in three groups of subjects to assess cognitive flexibility and functional magnetic resonance imaging(fMRI)scans was used to assess the FC.The differences of cogni-tive flexibility were found between three groups of subjects.The differences of FC between the bilateral(Left and Right,L.and R.)striatum(ST)and the dorsolateral prefrontal cortex(dlPFC)were found between three groups of subjects.Further analysis was focused on the interactive effect of T2DM and cognitive flexibility on FC changes.Results:Com-pared with T2DM-CD and HC,the number of response administered,errors responses,perseverative response,and time in WCST of T2DM+CD were significantly increased,while the number of correct responses was decreased.In Stroop,the number of correct,word-color contradiction and correct word-color indifference in T2DM+CD were lower than HC.In T2DM+CD,FC between L.ST-L.dlPFC,R.ST-L.dlPFC and R.ST-R.dlPFC were decreased,and decreased FC between R.ST-R.dlPFC was associated with cognitive flexibility scale scores.There existed an interactive effect between T2DM and cognitive flexibility on FC changes.Conclusion:Decreased FC between ST and dlPFC is the neural mechanism of cognitive flexibility impairment in T2DM.

BACKGROUND: Butylphthalide (NBP) and edaravone (EDV) injection are common acute ischemic stroke medications in China, but there is a lack of large real-world safety studies on them. This study aimed to determine the incidence of adverse events, detect relevant safety signals, and assess the risk factors associated with these medications in real-world populations. METHODS: In this study, data of acute ischemic stroke patients were extracted from the electronic medical record database of six tertiary hospitals between January 2019 and August 2021. Baseline confounders were eliminated using propensity score matching. The drugs' safety was estimated by comparing the results of 24 laboratory tests standards on liver function, kidney function, lipid level, and coagulation function. The drugs' relative risk was estimated by logistic regression. A third group with patients who did not receive NBP or EDV was constructed as a reference. Prescription sequence symmetry analysis was used to evaluate the associations between adverse events and NBP and EDV, respectively. RESULTS: 81,292 patients were included in this study. After propensity score matching, the NBP, EDV, and third groups with 727 patients in each group. Among the 15 test items, the incidence of adverse events was lower in the NBP group than in the EDV group, and the differences were statistically significant. The multivariate logistic regression equation revealed that NBP injection was not a promoting factor for abnormal laboratory test results, whereas EDV had statistically significant effects on aspartate transaminase, low-density lipoprotein cholesterol and total cholesterol. Prescription sequence symmetry analysis showed that NBP had a weak correlation with abnormal platelet count. EDV had a positive signal associated with abnormal results in gamma-glutamyl transferase, alanine aminotransferase, aspartate aminotransferase, prothrombin time, and platelet count. CONCLUSIONS In a large real-world population, NBP has a lower incidence of adverse events and a better safety profile than EDV or other usual medications.

Posttranslational modifications of antibody products affect their stability,charge distribution,and drug activity and are thus a critical quality attribute.The comprehensive mapping of antibody modifications and different charge isomers(CIs)is of utmost importance,but is challenging.We intended to quanti-tatively characterize the posttranslational modification status of CIs of antibody drugs and explore the impact of posttranslational modifications on charge heterogeneity.The CIs of antibodies were fraction-ated by strong cation exchange chromatography and verified by capillary isoelectric focusing-whole column imaging detection,followed by stepwise structural characterization at three levels.First,the differences between CIs were explored at the intact protein level using a top-down mass spectrometry approach;this showed differences in glycoforms and deamidation status.Second,at the peptide level,common modifications of oxidation,deamidation,and glycosylation were identified.Peptide mapping showed nonuniform deamidation and glycoform distribution among CIs.In total,10 N-glycoforms were detected by peptide mapping.Finally,an in-depth analysis of glycan variants of CIs was performed through the detection of enriched glycopeptides.Qualitative and quantitative analyses demonstrated the dynamics of 24 N-glycoforms.The results revealed that sialic acid modification is a critical factor ac-counting for charge heterogeneity,which is otherwise missed in peptide mapping and intact molecular weight analyses.This study demonstrated the importance of the comprehensive analyses of antibody CIs and provides a reference method for the quality control of biopharmaceutical analysis.

Objective: To summarize the clinical characteristics of patients with Takotsubo syndrome (TTS) from China and compare these features with patients from Europe/North America. Methods: We reviewed case reports published between 1990 and 2020 with the key words of "Takotsubo syndrome" "stress cardiomyopathy" "apical balloon syndrome" and "broken heart syndrome", in Wanfang, CNKI, Pubmed and Web of Science databases, and 1 294 articles were identified, including 128 articles reporting 163 cases in China and 1 166 articles reporting 1 256 cases in Europe/North America. The characteristics of demographics, triggers, symptoms, electrocardiogram, echocardiography, left ventriculogram,coronary angiography, treatment and prognosis were analyzed and compared between Chinese and European/North American cases. Results: A total of 1 294 articles (1 419 cases: 163 from China, 1 256 from Europe/North America) were included in the final analysis. The characteristics of Chinese cases included: (1) demographic:the age was (59.6±16.9) years, which was similar with that of European/North American ((59.7±17.4) years, P=0.90), and female accounting for 78.5% (128/163), which was lower than that of European/North American (85.4% (1 073/1 256), P=0.02). (2) Triggers:mental triggers accounted for 48.5% (79/163), physical triggers accounted for 43.6% (71/163), and no triggers accounted for 7.9% (13/163), respectively. Compared with Europe/North America, the ratio of patients with mental triggers was higher in China, while the ratio of patients with physical triggers and no triggers was lower (P<0.05).

Compared with patients in Europe/North America, the ratio of patients with chest tightness, dizziness, sweating, palpitations, abdominal pain/diarrhea was higher in Chinese patients, while the ratio of patients with hypotension was lower in Chinese patients (P<0.05). (4) Electrocardiogram: main manifestations were myocardial ischemia symptoms, such as ST-segment elevation (63.8% (104/163)), T wave inversion (46.0% (75/163)), ST-segment depression (8.6% (14/163)). Compared with European/North American, the ratio of patients with ST-segment elevation, T wave inversion, and atrioventricular block was higher in Chinese patients (P<0.05). (5) Echocardiography and imaging:apical dyskinesia (59.5% (97/163)) and apical/left ventricular bulbar dilation (36.2%(59/163)) dominated the echocardiography findings. Compared with European/North American, the ratio of patients with apical dyskinesia, apical/left ventricular bulbar dilation, and mitral regurgitation was higher in Chinese patients, while the ratio of patients with dyskinesia in other parts and left ventricular ejection fraction<50% was lower in Chinese patients (P<0.05). Left ventricular angiography showed 36.2% (59/163) of apical dyskinesia in Chinese patients, which was higher than that reported in European/North American patients, and 38.7% (63/163) of apical/left ventricular bulbar dilation was reported in Chinese patients, which was similar to that reported in European/North American patients. Coronary angiography showed percent of no stenosis or stenosis less than 50% was 87.1% (142/163), which was similar to that reported in European/North American patients (P>0.05). The typical type of TTS accounted for 96.3% (157/163), which was significantly higher than that reported in European/ American patients, while the ratio of basal type and midventricular type was lower (P<0.01).

Objective: To explore the basic psychological and personality characteristics of patients with laryngopharyngeal reflux disease (LPRD). Methods: The Minnesota Multiphasic Personality Inventory (MMPI) was used to investigate the psychological personality characteristics of 187 patients with LPRD (Study Group) and 75 healthy subjects (control group) who were treated in the otolaryngology clinic of Wuhan Central Hospital from January 2018 to December 2019. There were 102 males in the study group, aged from 20 to 71 (45.42±10.67) years and 85 females, aged from 18 to 65 (40.97±11.53) years; There were 41 males in the control group, aged from 18 to 67 (41.08±12.03) years and 34 females, aged from 20 to 65 (42.55±12.78) years. SPSS 24.0 software was used for statistical analysis. Results: The T scores of HS hypochondriac scale, D depression scale, Hy hysteria scale, Ma hypomania scale and MAS explicit anxiety scale in LPRD patients were significantly higher than those in healthy controls (t=6.304, 4.293, 5.750, 2.694, 5.178, all P<0.05). Correlation analysis showed that RSI score was positively correlated with T score of HS hypochondriac scale, Hy hysteria scale, Ma hypomania scale and MAS explicit Anxiety Scale (r=0.621, 0.402, 0.393, 0.581, all P<0.05); RFS score was positively correlated with T score of HS hypochondriac scale, Hy hysteria scale and MAS explicit Anxiety Scale (r=0.315, 0.321, 0.375, P<0.05). Conclusions: Compared with healthy people, LPRD patients have special personality psychological characteristics, which are mainly manifested as excessive attention to themselves, exaggerated illness, depression, sensitivity, somatization of psychological problems, irritability and mania. The severity of both subjective symptoms (RSI) and objective signs (RFS) of LPRD patients are related to their psychological personality characteristics.

OBJECTIVE: To investigate the clinical efficacy of zero-profile anchored spacer (ROI-C) in treating cervical spondylosis with osteoporosis. METHODS: From May 2013 to May 2018, a total of 145 patients with cervical spondylosis were treated by ROI-C through anterior cervical spine approach. Among them, 31 patients were aged ≥60 years and had osteoporosis by bone density measurement, and they were retrospectively analyzed. Including 9 males and 22 females, aged 60-84 years old with an average of (69.12±7.65) years. There were 23 cases of single-segment fusion, 6 cases of two-stage fusion, and 2 cases of three-stage fusion;and 41 devices of ROI-C fusion was placed in the patients. Operation time and intraoperative blood loss were recorded;Japanese Orthopaedic Association (JOA) scores and visual analogue scale(VAS) were respectively used to evaluate the neurological function and neck pain before and after operation. The cervical curvature (expressed as Cobb angle), the height of the intervertebral space at the surgical segment, and the intervertebral fusion were observed at postoperative and follow-up periods were observed by image data. RESULTS: All patients were followed up for 12-24(15.6±4.4) months after operation. The operation time were from 75 to 113 (101.33±10.25) min and intraoperative blood loss were from 14 to 51 (33.18 ± 16.56) ml. Among these 23 patients with fusion of single segment, the operation time were 75 to 98 (85.47±8.70) min and intraoperative blood loss were 14 to 30(21.18±6.56) ml. JOA scores of all included patients were increased from 9.66±2.12 preoperatively to 14.36±1.24 at the final follow-up ( CONCLUSION Anterior cervical approach with ROI-C for the treatment of elderly patients with cervical spondylosis and osteoporosis had reliable clinical effect, short operation time, less intraoperative blood loss, and can effectively restore cervical curvature and intervertebral space height, and has advantages of fewer complications and higher successful rate of fusion.
