The rapid development of artificial intelligence （AI） technology provides new opportunities for the modernisation of traditional Chinese medicine （TCM） diagnosis. By analysing the foundation， research progress and difficulties of the combination of AI and TCM diagnosis， it is concluded that AI has made remarkable development in intelligence-driven modernization of TCM tongue diagnosis， pulse diagnosis， listening and smelling diagnosis and text processing， and there are useful explorations in the field of constructing data-driven TCM diagnostic model and multidisciplinary integration of TCM diagnostic models. However， the current integration of AI technology in TCM diagnosis still faces many challenges， such as the scarcity and uneven quality of clinical data， the limited ability of AI algorithms to express TCM thinking model of syndrome differentiation and empirical knowledge， and the possible existence of ethical and privacy issues. By systematically sorting out the current research status and development direction of AI-empowered TCM diagnostics， it is proposed to promote the application of AI technology in TCM diagnostics in four aspects， namely， strengthening the construction of TCM big data and talent cultivation， encouraging cross-disciplinary cooperation， improving the legal and ethical framework， and promoting the popularity of the technology in primary care， so as to enhance the modernisation of TCM diagnostics.

Objective To explore the potential categories and influencing factors of the fear of progression in patients with inflammatory bowel diseases(IBD).Methods IBD patients who received inpatient treatment in a tertiary hospital in Nanjing from July 2022 to July 2023 were selected as the study subjects by convenience sampling method.The General Demographic Information Questionnaire,the Chinese version of the Fear of Progression Questionnaire-Short Form(FoP-Q-SF),the Chinese version of Inflammatory Bowel Disease Self-efficacy Scale(IBD-SES),and Social Support Rating Scale(SSRS)were administered to the participants.We applied one-way ANOVA and Logistic regression analysis to identify the factors associated with the potential categories of the fear of progression.Results A total of 303 retumed questionnaires(out of the 310)were valid,resulting an effective response rate of 97.74％.According to the results of latent profile analysis,we classified the respondents into 3 categories by the fear of progression,namely"low risk fear of disease adaptation group"(n=127,41.91％),"medium risk fear of illness distress group"(n=139,45.88％),"high risk fear of dysfunction group"(n=37,12.21％).3 groups showed statistically significant differences in permanent address,self-rated financial pressure,current disease status and self-efficacy(P＜0.05).Conclusion Patients with IBD had obvious differences in characteristics on the fear of progression.Nursing personnel should formulate personalized intervention strategies based on the classification characteristics of the fear of progression of IBD patients.Moreover,nurses should focus on improving patients'self-efficacy and promoting patients to treat medical care,stress and emotion management correctly.

To examine the molecular epidemiology of carbapenem-resistant Klebsiella pneumoniae (CRKP) and investigate the horizontal transmission of blaKPC and blaNDM genes for the prevention and treatment of CRKP. A total of 49 clinically isolated CRKP strains were retrospectively analyzed from January to December 2022 at The First Hospital of Hunan University of Chinese Medicine. Phenotypic screening was performed using modified carbapenem inactivation assay (mCIM) and EDTA-carbapenem inactivation assay (eCIM). Polymerase chain reaction (PCR) was utilized to identify carbapenem resistance genes, β-lactamase resistance genes, and virulence genes, while multi-locus sequence analysis (MLST) was employed to assess the homology of CRKP strains. Conjugation experiments were conducted to infer the horizontal transmission mechanism of blaKPC and blaNDM genes. The results showed that the study included 49 CRKP strains, with 44 carrying blaKPC and 8 carrying blaNDM, Three strains were identified as blaKPC+ blaNDM-CRKP. In this study, 28 out of 49 CRKP strains (57.2%) were found to carry virulence genes. Additionally, one CRKP strain tested positive in the string test and was found to carry both Aerobactin and rmpA virulence genes. MLST results revealed a total of 5 ST types, with ST11 being predominant (41/49, 83.7%). Successful conjugation was observed in all 3 blaKPC-CRKP strains, while only 1 out of 3 blaNDM-CRKP strains showed successful conjugation. The transconjugant exhibited significantly reduced susceptibility to imipenem and cephalosporin antibiotics. In conclusion, the resistance mechanism of CRKP in this study is primarily attributed to the production of KPC enzymes, along with the presence of multiple β-lactamase resistance genes. Additionally, there is a local prevalence of hv-CRKP and blaKPC+ blaNDM-CRKP. blaKPC and blaNDM can be horizontally transmitted through plasmids, with varying efficiency among different strains.

Objective:To translate the Illness Identity Questionnaire (IIQ) into Chinese and test its reliability and validity.Methods:The English version of IIQ was translated into Chinese and back-translated according to the Brislin model. The item of the Chinese version was determined after cross-cultural adaptation and pre-experiment. A total of 368 patients with IBD treated in the First Affiliated Hospital with Nanjing Medical University from September 2022 to March 2023 were selected for a questionnaire survey to evaluate the reliability and validity of the questionnaire.Results:The Chinese version of IIQ contained 24 items in four dimensions. Four common factors were extracted by exploratory factor analysis, and the cumulative variance contribution rate was 64.025%. Confirmatory factor analysis showed that each fitting index of the modified model was within the acceptable range. The Cronbach's α coefficients of rejection, acceptance, engulfing, and enrichment in Chinese IIQ were respectively 0.780, 0.800, 0.921, and 0.917. The split-half reliability coefficients were 0.824, 0.818, 0.943, and 0.929; the retest reliability coefficients were 0.695, 0.667, 0.725, and 0.572, respectively.Conclusions:The Chinese version of IIQ is reliable and valid and can be used to assess illness identity in patients with chronic diseases.

This research reviewed the origin, connotation, assessment tools, and summarized the performance level, influencing factors and intervention studies of illness identity in patients with chronic disease. It would provide references for research of illness identity, and to provide new ideas for promoting patients with chronic diseases to cope with and manage diseases.

Objective:To establish a xenograft model of cutaneous squamous cell carcinoma (CSCC) in nude mice, and to explore mechanisms underlying synergistic induction and promotion of CSCC in nude mice by ultraviolet radiation and human papillomavirus (HPV) infection.Methods:The human CSCC A431 cells were divided into 3 groups, namely HPV16 E6 overexpression group (LV-OE-HPV16 E6 group) transfected with adenovirus-mediated HPV16 E6 gene, empty vector group transfected with empty adenovirus vectors, and blank control group remaining untransfected. Using serum-free Dulbecco′s modified Eagle′s medium (DMEM) , A431 cells in the empty vector group and LV-OE-HPV16 E6 group were prepared into single-cell suspensions, which were subcutaneously inoculated into the left buttocks of SKH-1 nude mice separately, namely empty vector group ( n = 16) and LV-OE-HPV16 E6 group ( n = 16) . Tumor growth was observed and recorded for the mice every 3 days. When the tumor size reached 150 mm 3, the modeling was considered successful. After successful modeling, 8 mice in each group were irradiated with ultraviolet light at a dose of 1 440 mJ·cm -2·d -1 for 12 minutes each time, the other 8 mice in each group received no ultraviolet radiation, that is to say, all the 32 mice were divided into 4 groups: empty vector group, empty vector + UV group, LV-OE-HPV16 E6 group, and LV-OE-HPV16 E6 + UV group. After 4-week radiation, these nude mice were sacrificed, tumor weight and volume were measured, a tumor growth curve was drawn, immunohistochemistry study, Western blot analysis and real-time fluorescence-based quantitative PCR (qRT-PCR) were conducted to determine the protein and mRNA expression of Wnt1 and β-catenin in CSCC tissues collected from nude mice, respectively. For normally distributed measurement data, analysis of variance was used for intergroup comparisons, and least significant difference- t test for multiple comparisons; for non-normally distributed measurement data, rank sum test was used for intergroup comparisons. Results:Compared with the empty vector group (2.20 ± 0.24 g) , the tumor weight significantly increased in the empty vector + UV group (2.90 ± 0.36 g, t = 4.39, P < 0.001) , LV-OE-HPV16 E6 group (3.19 ± 0.32 g, t = 6.77, P < 0.001) , and LV-OE-HPV16 E6 + UV group (4.41 ± 0.18 g, t = 20.11, P < 0.001) ; the tumor volume was also significantly higher in the empty vector + UV group (1 033.12 ± 400.15 mm 3, t = 1.90, P < 0.001) , LV-OE-HPV16 E6 group (1 119.21 ± 447.57 mm 3, t = 2.21, P < 0.001) , and LV-OE-HPV16 E6 + UV group (1 464.29 ± 409.98 mm 3, t = 4.22, P < 0.001) than in the empty vector group (688.94 ± 319.31 mm 3) . Immunohistochemical study showed no significant difference in the protein expression of Wnt1 and β-catenin among the 4 groups ( F = 0.76, 0.71, respectively, both P > 0.05) ; Western blot analysis showed significant differences in the protein expression levels of Wnt1 and β-catenin among the 4 groups ( F = 16.74, 49.90, respectively, both P < 0.05) , which were significantly higher in the LV-OE-HPV16 E6 + UV group than in the empty vector group, empty vector + UV group and LV-OE-HPV16 E6 group (all P < 0.05) . qRT-PCR showed a significant difference in the mRNA expression of Wnt1 and β-catenin among the 4 groups ( F = 7.77, 8.38, respectively, both P<0.05) , and the LV-OE-HPV16 E6 + UV group showed significantly increased Wnt1 mRNA expression levels compared with the empty vector group, empty vector + UV group and LV-OE-HPV16 E6 group (all P < 0.05) . Conclusion:Ultraviolet radiation and HPV infection showed synergistic effect on the induction and promotion of CSCC.

Objective:To investigate the clinicopathological features and factors related to recurrence in patients with cutaneous squamous cell carcinoma (CSCC).Methods:The clinical and pathological data of 279 patients with CSCC diagnosed by histopathology in department of dermatology, plastic surgery, burns and oral and maxillofacial surgery of People′s Hospital of Xinjiang Uygur Autonomous Region from 2008 to 2019 were collected. They were divided into relapse group ( n=114) and non relapse group ( n=165) according to postoperative recurrence. Univariate and multivariate logistic analysis were used to analyze the related factors of CSCC recurrence. Results:Among 279 patients with CSCC surgery, the ratio of male to female was about 1.82∶1; the average age of onset (59.3±14.2)years, age ≥60 years (58.1%) was significantly higher; the average course of disease was 24 months; the incidence of exposed sites (88.2%) was significantly higher than that of non-exposed sites (11.8%); the degree of pathological differentiation was 182(65.2%) cases; postoperative wound healing: good 244 cases (87.5%), poor healing 35 cases (12.5%); first postoperative pathological margin: 239(85.7%) negative and 40(14.3%) positive; 60(21.5%) cases had lymph node metastasis occurred at the CSCC of diagnosis, and 219(78.5%) did not occur. Univariate analysis and multivariate logistic regression showed that the course of disease, the location of the disease, the healing of the postoperative area, the pathological condition of the first incision margin, and whether there was lymph node metastasis at the time of diagnosis were related to the recurrence of CSCC ( OR all >1.6). In addition, the correlation between gender, age, lesion length, preoperative skin ulceration, pathological differentiation, adjuvant radiotherapy and other factors on the recurrence of CSCC was not clear, with no statistically significant difference ( P>0.05). Conclusions:The course of disease (≥ 20 months), the site of the disease (the exposed part of the head), the wound healing (poor), the pathological condition of the first margin (positive) and the lymph node metastasis (with metastasis) were the risk factors for recurrence of CSCC. Early and accurate diagnosis is of great significance for the prognosis of CSCC, especially for patients with independent risk factors, early sentinel lymph node biopsy can detect metastasis and deal with it in time, so as to improve the prognosis of CSCC patients.

Objective    To study the learning curve of minimal invasive coronary artery bypass grafting (MICS CABG) and the influence on the perioperative clinical effects by analyzing operation time. Methods    From March 2012 to November 2020, 212 patients underwent MICS CABG by the same surgeon. Among them, 59 patients (52 males and average age of 62.89±8.27 years) with single vessel bypass grafting were as a single-vessel group and 153 patients (138 males, average age of 59.80±9.22 years) with multi-vessel bypass grafting were as a multi-vessel group. Two sets of operation time-operation sequence scatter plots were made and learning curve was analyzed by cumulative summation (CUSUM) and regression method of operation time. The surgical data of each group before and after the inflection point of the learning curve were compared with the main clinical outcome events within 30 days after surgery. Results    There was no death, perioperative myocardial infarction and stroke in 212 MICS CABG patients and no transfer to cardiopulmonary bypass or redo thoracotomy. The learning curve conformed to the cubic fitting formula. In the single- vessel group, CUSUM (x operation number)=–1.93+93.45×x–2.33×x2+0.01×x3, P=0.000, R2=0.986, the tipping point was 27 patients. In the multi-vessel group, CUSUM (x)=y=2.87+1.15×x–1.29× x2+3.463×x3, P=0.000, R2=0.993, and the tipping point was 59 patients. The two sets of case data were compared before and after the learning curve and there was no statistical difference in main clinical outcomes within 30 days (mortality, acute myocardial infarction, stroke, perioperative blood transfusion rate), ventilator tube, and intensive care unit retention. Conclusion    The learning curve of MICS CABG conforms to the cubic formula, and the process transitions from single to multiple vessels bypass. To enter the mature stage of the learning phase, a certain number of patients need to be done. Reasonable surgical procedures and quality control measures can ensure the safety during the learning phase.
