Turning to critical illness is a common stage of various diseases and injuries before death. Patients usually have complex health conditions, while the treatment process involves a wide range of content, along with high requirements for doctor′s professionalism and multi-specialty teamwork, as well as a great demand for time-sensitive treatments. However, this is not matched with critical care professionals and the current state of medical care in China. Telemedicine, which shortens the distance of medical professionals and the gap of disease diagnosis and treatments in various regions through electronic information, can effectively solve the current problem. Therefore, there is an urgent need to develop a standardized, high-quality visualization telemedicine round system .Therefore, experts have been organized to search domestic and foreign literature on telemedicine round for critically ill patients and to form this consensus based on clinical experiences so as to further improve the level of critical care treatments in regions.

OBJECTIVE To establish an evaluation index system for the selection of therapeutic drugs for colorectal carcinoma， providing a basis for clinical medication decision-making. METHODS A preliminary framework for the evaluation index system for the selection of therapeutic drugs for colorectal carcinoma was constructed through literature research and expert surveys. Using the Delphi method， consultations were conducted with 40 experts engaged in the use and evaluation of antitumor drugs， ultimately forming the evaluation system for selecting therapeutic drugs for colorectal carcinoma. RESULTS The effective recovery rate of questionnaires for both rounds of inquiries was 100%， with the reliability coefficients of 0.82 and 0.85. The Kendall’s W coordination coefficients were 0.251 and 0.252 （the P values of χ 2 tests were both less than 0.05）. The final evaluation system constructed included 6 first-level indicators （safety， efficacy， cost-effectiveness， suitability， innovation， and accessibility） and 29 second-level indicators （such as disease control rate， precise treatment of target diseases， objective remission rate， and whether clinical medication complies with authoritative recommendations）. Among these， efficacy and accessibility received high average importance scores （4.60， 4.30 points）， with “disease control rate” and “precision treatment for target disease” carrying relatively high weights （both were 0.035 2）. CONCLUSIONS This study successfully established a drug evaluation index system for the selection of therapeutic drugs for colorectal cancer that aligns with clinical practice.

Objective:To investigate the clinical efficacy and safety of ixazomib-containing regimens in the treatment of patients with multiple myeloma(MM).Methods:A retrospective analysis was performed on the clinical efficacy and adverse reactions of 32 MM patients treated with a combined regimen containing ixazomib in the Hematology Department of the First People's Hospital of Lianyungang from January 2020 to February 2022.Among the 32 patients,15 patients were relapsed and refractory multiple myeloma(R/RMM)(R/RMM group),17 patients who responded to bortezomib induction therapy but converted to ixazomib-containing regimen due to adverse events(AE)or other reasons(conversion treatment group).The treatment included IPD regimen(ixazomib+pomalidomide+dexamethasone),IRD regimen(ixazomib+lenalidomide+dexamethasone),ICD regimen(ixazomib+cyclophosphamide+dexamethasone),ID regimen(ixazomib+dexamethasone).Results:Of 15 R/RMM patients,overall response rate(ORR)was 53.3％(8/15),among them,1 achieved complete response(CR),2 achieved very good partial response(VGPR)and 5 achieved partial response(PR).The ORR of the IPD,IRD,ICD and ID regimen group were 100％(3/3),42.9％(3/7),33.3％(1/3),50％(1/2),respectively,there was no statistically significant difference in ORR between four groups(x2=3.375,P=0.452).The ORR of patients was 50％after first-line therapy,42.9％after second line therapy,60％after third line therapy or more,with no statistically significant difference among them(x2=2.164,P=0.730).In conversion treatment group,ORR was 88.2％(15/17),among them,6 patients achieved CR,5 patients achieved VGPR and 4 patients achieved PR.There was no statistically significant difference in ORR between the IPD(100％,3/3),IRD(100％,6/6),ICD(100％,3/3)and ID(60％,3/5)regimen groups(x2=3.737,P=0.184).The median progression-free survival(PFS)time of R/RMM patients was 9 months(95％CI:6.6-11.4 months),the median overall survival(OS)time was 18 months(95％CI:11.8-24.4 months).The median PFS time of conversion treatment group was 15 months(95％CI:7.3-22.7 months),the median OS time not reached.A total of 10 patients suffered grade 3-4 adverse event(AE).The common hematological toxicities were leukocytopenia,anemia,thrombocytopenia.The common non-hematological toxicities were gastrointestinal symptoms(diarrhea,nausea and vomit),peripheral neuropathy,fatigue and infections.Grade 1-2 peripheral neurotoxicity occurred in 7 patients.Conclusion:The ixazomib-based chemotherapy regimens are safe and effective in R/RMM therapy,particularly for conversion patients who are effective for bortezomib therapy.The AE was manageable and safe.

Aim To explore the effect and mechanism of the artesunate(ART)on hepatocellular carcinoma(HCC).Methods The cell lines MHCC-97H and HCC-LM3 were used to be detected.MTT and clone formation were used to determine the cell proliferation;Wound healing was used to detect the cell migration;Transwell was used to test the cell invasion.Flow-cy-tometry was used to detect cell apoptosis and cell cy-cle.RNA-seq and qRT-PCR was used to detect the genes expression.Results The proliferation,migra-tion and invasion of treated cells were obviously inhibi-ted(P＜0.01).Moreover,the apoptosis rate in-creased significantly,so did the proportion of G2/M cells.Transcriptomic analysis identified GADD45A as a potential target of ART through RNA-sequencing da-ta,and suggested that ART might induce apoptosis and cell cycle arrest through regulating the expression of GADD45A.In addition,the results of mechanism studies and signaling analysis suggested that GADD45A had interaction with its upstream gene NACC1(nucle-us accumbens associated 1).Moreover,after ART treatment,the expressions of GADD45A and NACC1 were changed significantly.Conclusion ART may be a potential drug to resist HCC by affecting the expres-sion of GADD45A and its upstream gene NACC1,which provides a new drug,a new direction and a new method for the clinical treatment of HCC.

Objective:To explore the clinical characteristics and prognostic influencing factors of multiple primary lung cancer (MPLC), and to construct a prognostic prediction model.Methods:The clinical data and prognostic information of MPLC patients diagnosed by pathological examination included in the Surveillance, Epidemiology, and End Results (SEER) database from January 2010 to December 2020 were retrospectively analyzed. Patients were randomly divided into training and validation sets according to a 7:3 ratio using R software. Survival curves were plotted by using the Kaplan-Meier method and log-rank test was used for comparison between groups. The independent influencing factors of overall survival (OS) of MPLC patients in the training set were screened using univariate and multivariate Cox proportional hazards models, and accordingly, the nomogram predicting the survival rate of patients at 3, 5 and 8 years were plotted. In the training and validation sets, using the actual survival as the gold standard, the receiver operating characteristic (ROC) curves of the constructed models for predicting the patients' 3-, 5- and 8-year OS rates were plotted, the area under the curve (AUC) was obtained, and C-index of the model was analyzed by using R software. The calibration curves of 3-, 5- and 8-year OS rates predicted by the models and the actual OS rates were plotted.Results:A total of 5 495 MPLC patients were included, 3 846 in the training set and 1 649 in the validation set. The differences in the composition of patients of different ages and AJCC stages between the training and validation sets were statistically significant (both P < 0.05), and the differences in the comparison of other clinicopathological characteristics were not statistically significant (all P > 0.05). The results of multivariate Cox regression analysis showed that males (compared with females, HR = 1.256, 95% CI: 1.144-1.379, P < 0.001), age ≥ 70 years old (compared with 50-59 years old, HR = 1.201, 95% CI: 1.030-1.400, P = 0.019), FPLC with pathological types of squamous cell carcinoma or other types (compared with adenocarcinoma, HR = 1.275, 95% CI: 1.137-1.431, P < 0.001; HR = 1.208, 95% CI: 1.041-1.403, P = 0.013), and SPLC with pathological types of squamous cell carcinoma, small cell lung carcinoma, or other types (compared with adenocarcinoma, HR = 1.270, 95% CI: 1.121-1.440, P < 0.001; HR = 1.978, 95% CI: 1.642-2.384, P < 0.001; HR = 1.246, 95% CI: 1.090-1.424, P = 0.001), and AJCC stage Ⅲ and Ⅳ (compared with stage Ⅰ, HR = 1.645, 95% CI: 1.447-1.869, P < 0.001; HR = 2.078, 95% CI: 1.669-2.587, P < 0.001), FPLC without operation (compared with operation, HR = 1.263, 95% CI: 1.038-1.536, P = 0.020), SPLC without operation (operation vs. no operation, HR = 0.680, 95% CI: 0.579-0.799, P < 0.001), FPLC without lymph node dissection or with clearance of 1-3 regional lymph nodes (compared with clearance of ≥4, HR = 1.225, 95% CI: 1.016-1.477, P = 0.034; HR = 1.314, 95% CI: 1.103-1.566, P = 0.002), FPLC with maximum diameter 3-5 cm or >5 cm (compared with <3 cm, HR = 1.181, 95% CI: 1.053-1.324, P = 0.005; HR = 1.232, 95% CI: 1.069-1.420, P = 0.004), and SPLC with maximum diameter 3-5 cm or >5 cm (compared with <3 cm, HR = 1.560, 95% CI: 1.362-1.786, P < 0.001; HR = 1.727, 95% CI: 1.451-2.054, P < 0.001), and FPLC without chemotherapy (chemotherapy vs. no chemotherapy or unknown, HR = 0.744, 95% CI: 0.655-0.845, P < 0.001) were the independent risk factors of patients' poor OS (all P < 0.05). The results of Kaplan-Meier survival analysis showed that the OS of patients with different gender, race, age, two tumor locations, AJCC staging, pathological type of two lung tumors, maximum diameter of two tumors, and whether two tumors were treated surgically or not, and whether two tumors were treated with chemotherapy or not in the training set were compared, and the differences were all statistically significant (all P < 0.05). Based on the independent factors affecting the OS of MPLC patients screened by the results of multivariate Cox regression analysis, nomogram predicting the 3-, 5- and 8-year OS rates of MPLC were plotted. The results of ROC curve analysis showed that the C-index of the training set's nomogram was 0.679 (95% CI: 0.649-0.701), and the AUC values for predicting the 3-, 5- and 8-year OS rates were 0.601, 0.595 and 0.586, respectively; the C-index of the validation set was 0.678 (95% CI: 0.633-0.720), and the AUC values for predicting 3-, 5- and 8-year OS rates were 0.643, 0.631 and 0.626, respectively. The calibration curves showed that the 3-, 5- and 8-year OS rates of patients predicted by the nomogram models in both the training and validation sets were in good agreement with the actual results with a high goodness-of-fit. Conclusions:The established prognostic model has good predictive value and can effectively assess the prognosis of patients.
