Objective To analyze the curative effect of acupuncture at Gongsun, Sifeng combined with visceral acupoint tapping in children with mesenteric lymphadenitis (type of gastrointestinal heat accumulation), and its influence on serum intestinal fatty acid-binding protein (I-FABP) and vasoactive intestinal peptide (VIP). Methods A total of 60 children with mesenteric lymphadenitis (type of gastrointestinal heat accumulation) were selected, and were divided into control group (n=30, conventional treatment combined with acupuncture at Gongsun and Sifeng acupoints) and study group (n=30, visceral acupoint tapping on the basis of the control group) according to the random number table method. The clinical efficacy, changes of main symptoms and signs were compared, and the expression levels of serum I-FABP and VIP were detected. Results The total effective rate of the study group was higher than that of the control group(P < 0.05). After 2 weeks of treatment, the serum I-FABP levels of the two groups were lower than that before treatment, and the serum I-FABP level of the study group was lower than that of the control group (P < 0.05). After 2 weeks of treatment, the serum VIP levels of the two groups were higher than that before treatment, and the serum VIP level of the study group was higher than that of the control group (P < 0.05). After 2 weeks of treatment, the improvement of main symptoms and signs in the study group was better than that in the control group (P < 0.05). Conclusion Acupuncture at Gongsun and Sifeng combined with visceral acupoint tapping can be used to treat children with mesenteric lymphadytis (gastrointestinal heat accumulation type), regulate and improve gastrointestinal function, adjust the level of serum I-FABP and VI, and relieve the main symptoms and signs of children, and can be used as an effective therapeutic method.

Objective To explore the association between death receptor (DR) 4 gene polymorphism and the predis-position of ulcerative colitis(UC). Methods DR4(rs20575)genotypes were determined by direct sequencing in a total of 147 UC patients and 244 healthy controls. Logistic regression analysis was employed to assess the relationship be-tween DR4 (rs20575)gene polymorphism and UC. Results Compared to the controls, the frequencies of variant allele(G)and genotype(CG+GG) of DR4(rs20575)were significantly increased in UC patients(5.78% vs 1.23%,P=0.001,OR=4.930,95%CI1.192-12.651;7.48% vs 2.46%,P=0.025,OR=3.208,95%CI1.161-8.869). According to the Tru-elove &Witt Activity Index, the severity of UC was further stratified into the mild, moderate and severe disease. In re-sult, variant allele (G)and genotype(CG+GG)in DR4(rs20575)were significantly higher in patients with moderate and severe UC than those with mild UC (10.64% vs 3.50%,P=0.020,OR=3.282,95%CI1.208-8.916; 14.89% vs 4.00%,P=0.028,OR=4.200,95%CI1.165-15.146). DR4(rs20575) mutant allele and genotype frequencies between extensive colitis and distal colitis were no statistical difference(P>0.05). Conclusion The genetic polymorphism of DR4(rs20575)is significantly related with the susceptibility to UC, as well as severity of the disease in this cohort of Chinese pa-tients.

Extensive genomic data concerning medicinal plants are rather scarce and insights of the secondary metabolic pathways and their regulatory mechanism are insufficient, hampering the broad application of cell or tissue cultivation and metabolic engineering to producing high-value secondary metabolites. The integration of cDNA-AFLP based transcript profiling and metabolomics, a new development of functional genomic approaches could establish correlations between the changes of secondary metabolites and expressions of related genes. It has manifested widely applicative prospects in seeking genes involved in biosynthesis of secondary metabolites and exploring secondary metabolic pathways. Functional genomic approaches are promising trends in the field of medicinal plants secondary metabolites research and will lead to better utilization of natural medicinal resources.

Objective:To explore the feasibility and safety of long-distance urological nephrotomy with the support of 5G communication technology by using the domestic robot.Methods:Clinical data of the patients with remote robot-assisted laparoscopic nephrectomy, which were completed from March to April 2021 by the Affiliated Hospital of Qingdao University (as the host hospital where the main operating system located) were retrospectively analyzed. There were 3 patients, including 2 males and 1 female.The average age was 61 (49-73) years, and the average body mass index was 23.73 (20.00-27.76) kg/m 2. One patient had a ASA classification of grade 2, and the other 2 patients had grade 3. All patients met the surgical criteria for non-functional nephrectomy. The chief surgeon who performing the telesurgery was located at the Affiliated Hospital of Qingdao University. The surgeon remotely controlled the bedside operating system (slave system) in 3 local hospitals located in other cities in Shandong Province (network communication distances of 82.5, 141 and 229 km, respectively) by manipulating the master system located in Qingdao. Images and operating instructions during surgery were transmitted using 5G wireless communication technology. Intraoperative network conditions, robot operation, and patient perioperative data were summarized. Results:All 3 tele-nephrectomies were successfully completed. The average network signal latency time was 27.3 (23-30) ms, with no packet loss, and the average total latency time was 177.3(173-180) ms. The mean resection time was 79.3 (52-111) min, and the average intraoperative blood loss was 31.1 (15.6-41.9) ml. There were no network related adverse events occurred during the operation, and the robot-related adverse events occured 3 times, all three of which were characterized by inconsistent master and slave movements of the manipulator arm and the bedside robotic arm. None of these adverse events affected the successful performance of the telesurgery. The mean postoperative exhaust time was 60.5 (38.5-78.0) h. The mean postoperative VAS score at 24 hours was 3.7 (3-4). The Clavien-Dindo classification were all grade I. No significant abnormality was found on the 30th day after surgery, and the patients recovered well at the follow-up until 6 months postoperatively.Conclusions:It is safe and feasible to perform remote robot-assisted laparoscopic nephrectomy based on 5G communication technology with no serious adverse events or surgical complications.However, the conclusion needs to be further verified by large sample and multi-center prospective study.
