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 investigate the efficacy and safety of autologous hematopoietic stem cell transplantation (ASCT) in the treatment of multiple myeloma (MM).Methods:The clinical data of 64 MM patients who received ASCT in the Second Affiliated Hospital of Xi'an Jiaotong University from October 2015 to March 2022 were retrospectively analyzed. The clinical characteristics, therapeutic effects and adverse reactions of the patients were summarized.Results:Of the 64 patients, 42 were male and 22 were female; the median age was 54 years old (37-69 years old). The median number of CD34 + cells collected from 46 patients in the CE (cyclophosphamide, etoposide) regimen mobilization group and 17 patients in the plerixafor mobilization group were 7.50×10 6/kg [(1.15-24.73)×10 6/kg] and 4.54×10 6/kg [(0.75-10.40)×10 6/kg], and the difference was statistically significant ( Z = 3.02, P = 0.024). Hematopoietic reconstitution was successful in all 64 patients, and the median time for white blood cell and platelet engraftment was 11 d (8-13 d) and 11 d (8-15 d), respectively. The patients' pretreatment regimens were all high-dose melphalan, the median white blood cell and platelet engraftment time of 29 patients in the oral group were 11 d (8-13 d) and 11 d (8-15 d), respectively, the median white blood cell and platelet engraftment time of 35 patients in the intravenous infusion group were 11 d (8-12 d) and 11 d (8-15 d), respectively, and there were no statistical differences (both P > 0.05). The ≥CR rate was 48.4% (31/64) before transplantation and 70.3% (45/64) three months after transplantation, and the difference was statistically significant ( χ2 = 6.35, P = 0.012). The median follow-up time of all patients was 27 months (2-67 months). The 3-year OS and PFS rates were 77.6% and 54.9%, and the median OS and PFS time were 67 and 52 months. The median hospitalization time was 20 d (15-37 d). There was no transplantation-related mortality, and the main adverse reactions were gastrointestinal reactions (100.0%, 64/64), grade 4 thrombocytopenia (98.4%, 63/64), grade 4 neutropenia, and agranulocytosis with fever (40.6%, 26/64). Conclusions:ASCT is effective for MM patients suitable for transplantation, which can further improve the remission rate and remission depth, prolong the PFS and OS time of patients, and the adverse reactions are controllable.

Objective:To investigate the application value of self-pulling and latter transection (SPLT) technique in double anti-reflux double-tract reconstruction of totally laparoscopic proximal gastrectomy.Methods:The retrospective cohort study was conducted. The clinicopatholo-gical data of 103 patients with Siewert type Ⅱ adenocarcinoma of esophagogastric junction in clinical stage Ⅰ-Ⅱ who were admitted to Shanxi Cancer Hospital from January 2018 to January 2020 were collected. There were 65 males and 38 females, aged from 45 to 79 years, with a median age of 59 years. Of 103 patients, 49 cases undergoing totally laparoscopic proximal gastrectomy with double-tract reconstruction of SPLT were assigned into the SPLT group, 54 cases undergoing totally laparoscopic proximal gastrectomy with conventional double-tract reconstruction were assigned into the traditional group. Observation indicators: (1) intraoperative situations; (2) postoperative situations; (3) follow-up. Follow-up was conducted by outpatient examination and telephone inter-view to detect postoperative reflux esophagitis of patients up to December 2021. Measurement data with normal distribution were represented as Mean± SD, and the t test was used for comparison between groups. Measurement data with skewed distribution were represented as M(range) or M( Q1, Q3), and the Wilcoxon test was used for comparison between groups. Count data were described as absolute numbers or percentages, and comparison between groups was performed using the chi-square test. Comparison of ordinal data was analyzed using the non-parameter rank sum test. Results:(1) Intraoperative situations: the operation time, digestive tract reconstruction time, volume of intraoperative blood loss, the number of inferior mediastinal lymph nodes dissected, cases with auxiliary incisions for the SPLT group were (261±48)minutes, (26±4)minutes, (114±42)mL, 8.0(6.5,9.5), 1, respectively. The above indicators were (244±42)minutes, (30±6)minutes, (118±46)mL, 5.5(4.0,8.0), 9 for the traditional group, respectively. There were significant differences in the digestive tract reconstruction time, the number of inferior mediastinal lymph nodes dissected and cases with auxiliary incisions between the two groups ( t=-3.34, Z=-4.05, χ2=4.72, P<0.05). There was no significant difference in the operation time or volume of intraoperative blood loss between the two groups ( t=1.87, -0.47, P>0.05). (2) Postoperative situations: duration of postopera-tive hospital stay and cases with postoperative complications were (11.5±2.7)days and 4 for the SPLT group, versus (12.5±4.3)days and 9 for the traditional group, showing no significant difference between the two groups ( t=-1.47, χ2=1.68, P>0.05). There were 13 of 103 patients with postopera-tive complications, including 5 cases of left pleural effusion, 4 cases of anastomotic leakage, 2 cases of mild pneumonia, 1 case of incision infection, 1 case of chylous leakage. Four patients had anasto-motic leakage at the esophagojejunostomy, the abdominal esophagus of whom was invaded by more than 1 cm. During the operation, mediastinal drainage tubes were placed through the abdominal wall. The 4 patients were cured after enteral and parenteral nutrition support and adequate drainage, and the remaining patients with complications were cured after symptomatic treatment. (3) Follow-up: of 49 patients in the SPLT group, 43 cases were followed up for (18±4)months. During the follow-up, 1 case showed reflux esophagitis by gastroscopy, with the incidence of 2.33%(1/43). Of 54 patients in the traditional group, 53 cases were followed up for (17±4)months. During the follow-up, 4 cases showed reflux esophagitis by gastroscopy, with the incidence of 7.55%(4/53). There was no significant difference in the incidence of reflux esophagitis between the two groups ( χ2=0.47, P>0.05). Conclusions:SPLT technology is feasible for double anti-reflux double-tract reconstruction of proximal gastrectomy. Compared with traditional double-tract reconstruction of totally laparos-copic proximal gastrectomy, SPLT technology can reduce the auxiliary incisions, increase the number of lower mediastinal lymph nodes dissected, and shorten the digestive tract reconstruction time.

Objective:To evaluate the safety and efficiency of a modified double-tract reconstruction procedure─proximal gastrectomy with piggyback interposed jejunal single-channel reconstruction (PJIR-STR) for early SiewertⅡ adenocarcinoma of esophagogastric junction (AEG).Method:Data of 8 SiewertⅡ AEG patients at Shanxi Tumor Hospital and undergoing PJIR-STR from May 2018 to Oct 2019 were retrospectively analyzed. The gastroesophageal reflux disease questionnaire (GerdQ) was used to score the patients at 3, 6, 12, and 18 months after surgery. The severity of postoperative reflux esophagitis was assessed by gastroscopy at 3, 6 months after surgery, using the Los Angeles Classification criteria.Result:All patients recovered well after surgery without serious complications. No obvious gastroesophageal reflux was observed in all patients at different periods (All of the GerdQ scores were <8 points.) The results of gastroscopy showed that 1 patient was diagnosed as grade B reflux esophagitis at 3, 6 months after surgery, which was responsive to conservative treatment, and the other 7 patients had no grade B or above reflux esophagitis.Conclusion:PJIR-STR is a feasible, safe reconstruction with excellent efficiency of dual anti-reflux for the SiewertⅡ AEG.

Objective To analyze the type and gene features of 11 unverified HAdVs in China. Methods We downloaded HAdV genome sequences of 67 strains with clear genotypes and the HAdV reference genome sequences of 7 strains from GenBank database, analyzed them together with eleven unverified HAdV gene sequences and classified the species of each sequence based on the genetic structure, sequence similarity and phylogenetic analysis. Results Phylogenetic analysis results predicted the classification of six sequences: two of them belonged to HAdV-B and two belonged to HAdV-D (the gene homology were 97.8% and 92.8% in comparison with reference gene respectively), the rest of two sequences were not conclusive. Multiple sequence alignment was used to predict the species of five HAdVs. All of them belonged to species HAdV-B, the sequence similarity compared with reference gene was 97.9%. Conclusion Genotyping of the unverified HAdV genome from a genetic point of view predicts that seven strains might belong to species HAdV-B, two strains might belong to species HAdV-D and two strains could not be classified. The seven HAdV-B strains might be suitable for the treatment of osteosarcoma as oncolytic adenovirus.

Objective:To understand the perceptions, attitudes and treatment selection of Chinese surgeons for proximal gastrectomy (PG) and digestive tract reconstruction.Methods:A cross-sectional survey was used in this study. Selection of subjects: (1) Domestic public grade IIIA (provincial and prefecture-level) tumor hospitals or general hospitals possessing the diagnosis and treatment qualifications for gastric cancer.(2) Surgeons with senior attending physician, associate chief physician and chief physician. The "Questionnaire Star" platform was used to design a questionnaire about cognition, attitude and treatment choice of "proximal gastrectomy and digestive tract reconstruction". The questionnaire contained 32 questions, such as the basic information of surgeons, the current status of gastric cancer surgery, the selection and management of surgical methods and related details for proximal gastric cancer, the choice of proximal gastrectomy and reconstruction of digestive tract, the related complications and nutritional status monitoring after proximal gastrectomy. A total of 76 questionnaires were linked to the respondents via WeChat between July 29 and August 25, 2019. Statistical analysis was performed using Chi-square test or Kruskal-Wallis test for categorical variables.Results:A total of 47 grade IIIA hospitals were included, and 76 questionnaires were sent out. The proportions of recovered and valid questionnaires were both 100%. For early and middle stage adenocarcinoma of esophagogastric junction (AEG), especially those smaller than 4 cm, 72.37% (55/76) of surgeons preferred proximal gastrectomy, while 22.37% (17/76) of surgeons chose total gastrectomy. For early AEG, 90.79% (69/76) of surgeons thought that endoscopic submucosal dissection (ESD) or proximal gastrectomy could be considered. For AEG below T3 stage and shorter than 4 cm, 60.53% (46/76) of surgeons gave priority to proximal gastrectomy, and 60.53% (46/76) of the surgeons believed that the advanced AEG with a higher radical cure should be treated with proximal gastrectomy, and the residual stomach should not be less than half stomach. Considering anti-reflux effect, postoperative weight recovery, clinical efficacy, wide application and easy popularization, surgeons preferred double-tract reconstruction. The surgeons in tumor hospitals had a higher approval rate for the application of proximal gastrectomy and the fact that the Kamikawa anastomosis was the most difficult to promote than the surgeons in provincial/municipal general hospitals. The surgeons with an annual surgical volume of more than 200 were more likely to choose proximal gastrectomy for early and middle stage AEG patients and the proportion was as high as 8/9. From the perspective of good clinical results, wide range of application, and easy popularization, the surgeons with a higher ratio (60.00%, 15/25) of double-tract reconstruction were those surgeons with 50-100 operations per year.Conclusions:The general level of cognition and acceptability of Chinese surgeons for proximal gastrectomy and reconstruction of digestive tract is suboptimal. In the future, it is urgent to promote the "Chinese consensus on digestive tract reconstruction after proximal gastrectomy" so as to guide and optimize treatment in proximal gastric cancer.
