Objective To evaluate the effects of transcutaneous electrical acupoint stimulation(TEAS)combined with Chinese medicine emotional intervention on immune function and psychological stress in patients undergoing laparoscopic radical rectal cancer surgery.Methods A total of 100 patients hospitalized for laparoscopic radical surgery for rectal cancer were randomly divided into 4 groups of Group A,B,C,and D,25 patients in each group.Group A was given TEAS for 30 minutes before anesthesia,Group B was given TEAS continuously until the end of the surgery,Group C was given TEAS for 30 minutes and Chinese medicine emotional intervention before anesthesia,Group D was given TEAS continuously until the end of the surgery together with Chinese medicine emotional intervention.TEAS was performed at bilateral Zusanli(ST36)points,bilateral Sanyinjiao(SP6)points,Baihui(GV20)points,bilateral Neiguan(PC6)points.The changes of perioperative outcomes and the changes of parameters associated with the immune function,molecular mechanism of Th1/Th2 cells,and psychological stress response before the surgery and 3 days after the surgery in each group were observed.Moreover,the occurrence of adverse reactions in each group was compared.Results(1)The differences of perioperative outcomes operation time,bleeding volume and infusion amount were not statistically significant among the 4 groups(P＞0.05).The Sufentanil dosage,Remifentanil dosage,postoperative awakening time,and 24-hour postoperative pain Visual Analogue Scale(VAS)scores of group D were lower than those of Groups A,B,and C(P＜0.05),and the above indexes of group B and group C were all lower than those of Group A(P＜0.05).(2)Three days after the surgery,the levels of immune function indicators of T lymphocyte subsets CD3+,CD4+ and natural killer(NK)cells in Group D were higher than those in Groups A,B,and C(P＜0.05),while the above indexes in Groups B and C were higher than those in Group A(P＜0.05).(3)Three days after the surgery,the levels of parameters associated with the molecular mechanism of Th1/Th2 cells such as interleukin 2(IL-2)and interferon gamma(IFN-γ)in Group D were higher(P＜0.05),and the serum interleukin 10(IL-10)level was lower than those in Groups A,B,and C(P＜0.05);the serum IL-2 and IFN-γ levels in Group B and C were higher(P＜0.05)and serum IL-10 level was lower than those in Group A(P＜0.05).(4)Three days after the surgery,the scores of the psychological stress response indicators of self-rating anxiety scale(SAS)and self-rating depression scale(SDS)in Group D were lower than those in Groups A,B,and C(P＜0.05),while the above scores in Groups B and C were lower than those in Group A(P＜0.05).(5)In Group A,there was one case of nausea and vomiting;in Group B,there were two cases of nausea and vomiting and one case of dizziness;no adverse reaction occurred in Group C,and there was one case of nausea and vomiting in Group D.The incidences of adverse reactions in Groups A,B,C and D were 4.0%(1/25),12.0%(3/25),0.0%(0/25),and 4.0%(1/25),respectively.The intergroup comparison showed no statistically significant difference among the 4 groups(χ2 = 0.400,P = 0.527).Conclusion In treating patients undergoing laparoscopic radical surgery for rectal cancer,TEAS combined with Chinese medicine emotional intervention can effectively regulate the perioperative immune function,reduce the stress response,and alleviate the anxiety of the patients.Moreover,the therapy exerts certain analgesic effect,which leads to the reduction of the dosage of opioids and the increase of perioperative comfort and surgical tolerance of the patients.

ObjectiveExisting artificial vision devices can be divided into two types: implanted devices and extracorporeal devices, both of which have some disadvantages. The former requires surgical implantation, which may lead to irreversible trauma, while the latter has some defects such as relatively simple instructions, limited application scenarios and relying too much on the judgment of artificial intelligence (AI) to provide enough security. Here we propose a system that has voice interaction and can convert surrounding environment information into tactile commands on head and neck. Compared with existing extracorporeal devices, our device can provide a larger capacity of information and has advantages such as lower cost, lower risk, suitable for a variety of life and work scenarios. MethodsWith the latest remote wireless communication and chip technologies, microelectronic devices, cameras and sensors worn by the user, as well as the huge database and computing power in the cloud, the backend staff can get a full insight into the scenario, environmental parameters and status of the user remotely (for example, across the city) in real time. In the meanwhile, by comparing the cloud database and in-memory database and with the help of AI-assisted recognition and manual analysis, they can quickly develop the most reasonable action plan and send instructions to the user. In addition, the backend staff can provide humanistic care and emotional sustenance through voice dialogs. ResultsThis study originally proposes the concept of “remote virtual companion” and demonstrates the related hardware and software as well as test results. The system can not only achieve basic guide functions, for example, helping a person with visual impairment to shop in supermarkets, find seats at cafes, walk on the streets, construct complex puzzles, and play cards, but also can meet the demand for fast-paced daily tasks such as cycling. ConclusionExperimental results show that this “remote virtual companion” is applicable for various scenarios and demands. It can help blind people with their travels, shopping and entertainment, or accompany the elderlies with their trips, wilderness explorations, and travels.

Objective: To analyze the risk factors for complications of endoscopic full-thickness resection (EFTR) of upper gastrointestinal submucosal tumors (SMTs). Methods: This was a retrospective observational study. The indications for EFTR included: (1) SMTs originating from the muscularis propria layer and growing out of the cavity or infiltrating the deep part of the muscularis propria layer; (2) SMTs diameter <5 cm; and (3) tumor identified as closely adherent to the serous layer during endoscopic submucosal dissection or endoscopic mucosal resection. This study included patients with SMTs originating from the muscularis propria layer in upper digestive tract, diagnosed preoperatively by endoscopic ultrasonography or computed tomography, who were successfully treated with EFTR. Those with incomplete clinical data were excluded. The clinical data of 154 patients with upper gastrointestinal SMTs who underwent EFTR at the Department of Gastroenterology, First Affiliated Hospital of Soochow University from January 2016 to January 2022 were retrospectively analyzed. Post-EFTR complications (such as delayed perforation, delayed bleeding, and postoperative infection, including electrocoagulation syndrome) were monitored and the risk factors for them were analyzed. Results: Among the 154 study patients, 33 (21.4%) developed complications, including delayed bleeding in three (1.9%), delayed perforation in two (1.3%), and postoperative infection in 28 (18.2%). One patient with bleeding was classified as having a major complication (hospitalized for more than 10 days because of complication). According to univariate analysis, complication was associated with tumor diameter >15 mm, operation time >90 minutes, defect closure method(purse string suture), and diameter of resected specimen ≥20 mm (all P<0.05). Multivariate logistic regression analysis showed that operation time >90 minutes (OR=6.252, 95%CI: 2.530-15.446, P<0.001) and tumor diameter >15 mm (OR=4.843, 95%CI: 1.985-11.817, P=0.001) were independent risk factors for complications after EFTR in patients with upper gastrointestinal SMTs. The independent risk factors for postoperative infection in these patients were operation time>90 minutes (OR=4.993, 95%CI:1.964-12.694, P=0.001) and purse string suture (OR=7.142, 95%CI: 1.953-26.123, P=0.003). Conclusion: Patients with upper gastrointestinal SMTs undergoing EFTR with tumor diameter >15 mm or operation time >90 minutes have a significantly increased risk of postoperative complications. Postoperative monitoring is important for these patients with SMTs.

OBJECTIVES: To investigate the clinical manifestations and laboratory examination results of children with Kawasaki disease complicated by macrophage activation syndrome (KD-MAS), and to provide a basis for identifying early warning indicators for the early diagnosis and treatment of KD-MAS. METHODS: A retrospective study was performed on 27 children with KD-MAS (KD-MAS group) and 110 children with KD (KD group) who were admitted to Wuhan Children's Hospital, Tongji Medical College, Huazhong University of Science and Technology, from January 2014 to January 2022. Clinical and laboratory data were compared between the two groups. The receiver operating characteristic (ROC) curve was used to investigate the value of laboratory markers with statistical significance in the diagnosis of KD-MAS. RESULTS: Compared with the KD group, the KD-MAS group had significantly higher incidence rates of hepatomegaly, splenomegaly, incomplete KD, no response to intravenous immunoglobulin, coronary artery damage, multiple organ damage, and KD recurrence, as well as a significantly longer length of hospital stay (P<0.05). Compared with the KD group, the KD-MAS group had significantly lower levels of white blood cell count, absolute neutrophil count, hemoglobin, platelet count (PLT), erythrocyte sedimentation rate, serum albumin, serum sodium, prealbumin, and fibrinogen (FIB), a significantly lower incidence rate of non-exudative conjunctiva, and significantly higher levels of C-reactive protein, alanine aminotransferase, aspartate aminotransferase, lactate dehydrogenase (LDH), and serum ferritin (SF) (P<0.05). The ROC curve analysis showed that SF, PLT, FIB, and LDH had high value in the diagnosis of KD-MAS, with areas under the curve (AUC) of 0.989, 0.966, 0.932, and 0.897, respectively (P<0.001), and optimal cut-off values of 349.95 μg/L, 159×10⁹/L, 3.85 g/L, and 403.50 U/L, respectively. The combination of SF, PLT, FIB, and LDH had a larger AUC than PLT, FIB, and LDH alone in the diagnosis of KD-MAS (P<0.05), but there was no significant difference in the AUC between the combination of SF, PLT, FIB, and LDH and SF alone (P>0.05). CONCLUSIONS KD-MAS should be considered when children with KD have hepatosplenomegaly, no response to intravenous immunoglobulin, coronary artery damage, and KD recurrence during treatment. SF, PLT, FIB, and LDH are of high value in the diagnosis of KD-MAS, especially SF is of great significance in the diagnosis of KD-MAS.
