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 evaluate the efficacy and safety of lenvatinib combined with camrelizumab as the second-line treatment for advanced intrahepatic cholangiocarcinoma (ICC).Methods:The clinical data of patients with advanced ICC undergoing the second-line treatment of lenvatinib combined with camrelizumab in the Affiliated Changzhou No. 2 People's Hospital of Nanjing Medical University from June 2021 to June 2022 were screened and analyzed. A total of 12 patients were enrolled, including seven males and five females, aged (67.5±8.6) years. Response evaluation criteria in solid tumor 1.1 was used to evaluate the efficacy of treatment. The safety assessment adopts the Adverse Event Evaluation Standard 5.0. Kaplan-Meier method was conducted to plot survival curves.Results:Among the 12 patients (after 1-7 cycles of immune and targeted therapy), three achieved partial response, four achieved stable disease, and five were defined as progression disease. Adverse events of different degrees occurred in seven cases, among which three patients had adverse events of grade ≥ 3: one with hypertension, which was managed after antihypertensive and symptomatic treatment; one with elevated serum total bilirubin, which was improved after reducing the dose of lenvatinib; one with liver dysfunction, which was considered as immune-related liver toxicity and alleviated after discontinuing camrelizumab. The 1-month, 3-month, and 6-month survival rates and progression-free survival rates of the patients were 100.0%, 91.7%, 66.7%, and 83.3%, 41.7%, and 25.0%, respectively. The median overall survival of patients was 14.7 months (95% CI: 9.2-21.2) and the median time to progression was 8.0 months (95% CI: 4.1-11.9). Conclusion:Combination of lenvatinib and camrelizumab could bring survival benefits with controllable adverse events as the second-line treatment of patients with advanced ICC.

Objective: Schizophrenia (SCZ) is one of the most common and severe mental disorders. Modified electroconvulsive therapy (MECT) is the most effective therapy for all kinds of SCZ, and the underlying molecular mechanism remains unclear. This study is aim to detect the molecule mechanism by constructing the transcriptome dataset from SCZ patients treated with MECT and health controls (HCs). Methods: Transcriptome sequencing was performed on blood samples of 8 SCZ (BECT: before MECT; AECT: after MECT) and 8 HCs, weighted gene co-expression network analysis (WGCNA) was used to cluster the different expression genes, enrichment and protein-protein interaction (PPI) enrichment analysis were used to detect the related pathways. Results: Three gene modules (black, blue and turquoise) were significantly associated with MECT, enrichment analysis found that the long-term potentiation pathway was associated with MECT. PPI enrichment p-value of black, blue, turquoise module are 0.00127, <1×10-16 and 1.09×10-13, respectively. At the same time, EP300 is a key node in the PPI for genes in black module, which got from the transcriptome sequencing data. Conclusion It is suggested that the long-term potentiation pathways were associated with biological mechanism of MECT.

Objective:To examine the correlations of C-reactive protein (CRP)/albumin ratio (CAR) with the postoperative complications of patients with colorectal cancer.Methods:The clinic data of 312 patients undergoing elective surgery for colorectal cancer in Hainan Hospital of People′s Liberation Army General Hospital between January 2013 and July 2018 was analyzed retrospectively. There were 188 males and 124 females, aged (61.0±12.9) years (range: 21 to 86 years). Logistic analysis was used to identify relative factors for postoperative complications. Receiver operating characteristic curves were developed to examine the cutoff values and compare diagnostic accuracy of the CAR and CRP levels.Results:Postoperative complications occured in 28.5% (89/312) cases. Hemoglobin on postoperative day(POD) 3 ( OR=0.977, 95% CI: 0.957 to 0.998, P=0.034), preoperative CRP ( OR=1.209, 95% CI: 1.055 to 1.386, P=0.006) and CAR on POD 3 ( OR=0.033, 95% CI: 0.016 to 0.067, P<0.01) were found to be significant independent relative factors for postoperative complications. The cutoff point of CAR on POD 3 was 0.325, patients with CAR≥0.325 were found to have more postoperative complications than those with CAR<0.325. The area under the curve of CAR on POD 3 and preoperative CRP were 0.872, 0.626, respectively. The positive predictive value of CAR on POD 3 was higher than that of preoperative CRP (79.9% vs. 55.1%). Conclusions:CAR is closely related to the occurrence of postoperative complications in colorectal surgery. Patients with CAR≥0.325 on POD 3 has higher incidence of postoperative complications.

Objective To investigate the clinical value of radiomics nomogram,which is established by 18F-fluorodeoxyglucose (FDG) PET/CT radiomics signature combined with clinical-pathologic risk factors,in predicting the prognosis of patients with postoperative gastric carcinoma.Methods 18F-FDG PET/CT data of 207 patients (143 males,64 females,age range:20-85 years) with postoperative gastric carcinoma from January 2008 to August 2015 was reviewed retrospectively.Patients were divided into training group (n=104) and validation group (n =103),and the clinicopathologic information and disease-free survival (DFS) data were acquired.Significant textural features were selected from PET/CT images,and radiomics score (RS) for individual patient was calculated based on the radiomics signatures.The relationship between RS and DFS was analyzed.Cox regression analysis was performed to determine the risk factors ofDFS.The radiomics nomo-gram,obtained from combination of RS with clinicopathologic risk factors,was established and further evaluated in predictive value for recurrence or metastasis of postoperative gastric carcinoma,and the concordance index (C-index) was calculated.Results Cox regression analysis demonstrated that RS,tumor location,depth of invasion,lymph node metastasis,and distant metastasis were the significant risk factors for DFS (hazard ratios:2.148-2.828,all P＜0.05).The radiomics nomogram combined with RS and 4 clinicopathologic risk factors had a better prediction for the estimated DFS,comparing to RS alone.C-index of radiomics nomogram and RS were 0.830 and 0.700 in training group,and 0.776 and 0.681 in validation group,respectively.Conclusion Radiomics nomogram which is established by radiomics signatures and clinicopathologic risk factors may be better for predicting DFS of patients with postoperative gastric carcinoma.

Objective: To compare the carcinogenic abilities of CD133⁺CD44⁺ laryngeal cancer stem cells and general laryngeal cancer stem cells and to identify the mechanism underlying the action of miRNAs. Methods: Solid tumor-derived laryngeal carcinoma stem cells and Hep-2-derived laryngeal carcinoma stem cells were cultured, and CD133⁺CD44⁺ laryngeal cancer stem cells were sorted by flow cytometry. Boden chamber invasion assay, cell migration assay and tumor formation assay were then performed to compare the invasion, migration and tumorigenic abilities of CD133⁺CD44⁺ laryngeal cancer stem cells and general laryngeal cancer stem cells. And then, miRNAs isolated from two laryngeal cancer stem cells were detected and analysed with miRNA chip. Results: (1)In Boyden chamber invasion assay, the cell invasion rate of CD133⁺CD44⁺ laryngeal cancer stem cells was obviously higher (80.2%±2.3% vs. 63.9%±3.2%, t=5.011, P=0.027); (2)CD133⁺CD44⁺ laryngeal cancer stem cells also had higher mobility in cell migration assay (82.9%±1.1% vs. 70.9%±0.6%, t=4.514, P=0.031); (3)In tumor formation assay, the tumor formation rate of CD133⁺CD44⁺ laryngeal cancer stem cells was also higher (80% vs. 50%). What′s more, we identified 15 miRNAs that were significantly upregulated in CD133⁺CD44⁺ laryngeal cancer stem cells and 3 miRNAs that were significantly downregulated in CD133⁺CD44⁺ laryngeal cancer stem cells, compared with normal laryngeal cancer stem cells. Conclusions CD133⁺CD44⁺ laryngeal cancer stem cells have stronger invasion, migration and tumorigenic abilities compared with normal laryngeal cancer stem cells, and the difference of miRNAs′ expression is one of the possible causes.

Objective To explore the effect of TGF-β microbubble targeting on the treatment of skeletal muscle injury in rats.MethodsEighty SD rats of 2 months old were randomly divided into experimental group(including TGF-β microbubble),pure drug group,microbubble group(exclusive drug) and control group,20 SD rats in each group.Four groups accepted ultrasonic transmission with consistent time and frequency.The contraction stress and stress relaxation of injured gastrocnemius muscle were measured,the changes of injured gastrocnemius muscle were observed by light microscope and electron microscope.Results There was no statistically significant difference in contraction stress of gastrocnemius muscle among all groups at 1,5,9 days after injury(P>0.05).And at 14 days,the contraction stress of gastrocnemius muscle of the experimental group and the pure drug group were obviously higher than those of the rest two groups,the differences were significant(P<0.05).The difference of gastrocnemius muscle contraction stress was statistically significant between the experimental group and the pure drug group(P<0.05).For the stress relaxation of gastrocnemius muscle,the experimental group was lower than the other three groups at 1 day after injury,the differences were significant(P<0.05).Light microscopy showed the number of muscle fiber in the experimental group increased obviously at 9 days after injury.There was no scarring at 14 days after injury.Electron microscope showed mitochondria and sarcoplasmic reticulum increased in the experimental group,and the new muscle cells and satellite cells were significantly more than those of the rest three groups.Conclusion TGF-β cell targeted therapy can obviously improve the shrinkage stress of skeletal muscle in rats after injury and recover the stress decay,which can obviously promote the injury repair and regeneration of skeletal muscle,and reduce scar formation at the same time.
