OBJECTIVE: To observe the effects of thumbtack-needle embedding therapy of auricular acupuncture on gastrointestinal function and intestinal microflora in the patients with gastric cancer after operation, and to explore its mechanism. METHODS: A total of 80 patients with gastric cancer after radical operation were randomly divided into an observation group (40 cases, 3 cases discontinued) and a control group (40 cases, 3 cases discontinued). The patients of both groups received the perioperative care for accelerating recovery. Additionally, in the observation group, the thumbtack-needle embedding therapy of auricular acupuncture was delivered at the auricular points of unilateral side, including Wei (CO₄), Pi (CO₁₃), Dachang (CO₇), Xiaochang (CO₆), Yuanzhong (AT_2,3,4i), Erzhong (HX₁), Sanjiao (CO₁₇) and Jiaowozhong (TF₃), and the needles were embedded and retained for 72 h. The postoperative recovery time of gastrointestinal function (the postoperative bowel sound recovery time, the first exhaust time, the first defecation time), the postoperative hospital stay and pain visual analogue scale (VAS) score were observed in the two groups. Before operation and on day 5 after operation, the serum gastrin level was detected in the two groups. The third-generation 16S rRNA sequencing technology was used to detect the composition and relative abundance of intestinal flora in the two groups before and after operation. RESULTS: Compared with the control group, the postoperative bowel sound recovery time, the first exhaust time and the first defecation time were shortened in the observation group (P<0.05). In the observation group, the VAS scores at 24 h, 48 h, and 72 h after surgery were lower than those of the control group, respectively (P<0.05). There was no significant differences in postoperative hospital stay and serum gastrin level between the two groups (P>0.05). The alpha diversity analysis showed that the differences in Shannon index, Simpson index, Pielou_J index and Pd_fath index were not significant statistically after intervention between the two groups (P>0.05). After intervention, the community structure of the fecal sample was similar at each taxonomic level between the two groups, and although the proportion between species was various, the difference was not significant (P>0.05). After intervention, there were 55 species with the differences between the two groups, 17 species of them presented significant difference in relative abundance in the observation group and 38 species in the control group. Regarding the level of genus, the levels of Klebsiell and Enterobacter increased (P<0.05) and the level of Streptococcus decreased (P<0.05) in the observation group. The main microbial groups that played an important role were Coprobacillaceae, Sutterellaceae and Yersiniaceae in the observation group. KEGG function prediction indicated that the function of intestinal microflora was mainly associated with the cofactor and vitamin metabolism, carbohydrate metabolism, and amino acid metabolism. CONCLUSION The thumbtack-needle embedding therapy of auricular acupuncture improves the postoperative gastrointestinal function of the patients with gastric cancer probably through regulating the structure and relative abundance of intestinal microflora and affecting the energy metabolism.

OBJECTIVE To establish the fingerprint of Sophora flavescens， and to screen differential components and determine their contents.　METHODS HPLC fingerprints of 12 batches of S. flavescens were established by using Similarity Evaluation System of Chromatographic Fingerprints of TCM （2012 edition）； common peaks were identified and their similarities were evaluated. Chemical pattern recognition analysis [cluster analysis （CA），principal component analysis （PCA） and orthogonal partial least squares-discriminant analysis（OPLS-DA）] were performed with SIMCA 14.1 and SPSS 23.0 software， and differential components which influenced the quality of S. flavescens were screen with variable importance in the projection（VIP）＞1 as standard. Meanwhile， the contents of 4 kinds of differential components were determined by the same HPLC method.　RESULTS There were 17 common peaks in the fingerprints of 12 batches of S. flavescens，and their similarities were all higher than 0.96. A total of 6 common peaks were identified， i.e. oxymatrine （peak 1）， oxysophocarpine （peak 2）， matrine （peak 10）， trifolirhizin （peak 14）， kurarinone （peak 16） and norkurarinone （peak 17）. Results of CA， PCA and OPLS-DA showed that 12 batches of S. flavescens were divided into 3 categories according to producing area， i.e. S1-S7 （Shangzhou District of Shaanxi Province） were grouped into one category， S8-S10 （Yichuan County of Henan Province） into one category and S11-S12 （Chifeng City of Inner Mongolia） into one category. VIPs of matrine， norkurarinone， kurarinone and oxysophocarpine and the chemical components represented by peak 11 and 9 were all greater than 1. The contents of matrine， norkurarinone， kurarinone and oxysophocarpine in 12 batches of S. flavescens were 2.65-4.93， 1.54-3.44， 9.63-12.94 and 5.08-6.10 mg/g， respectively. CONCLUSIONS HPLC fingerprint of S. flavescens is established successfully in the study， and can be used to screen 6 differential components by combining with chemical pattern recognition analysis， which can provide reference for quality control of S. flavescens.

Objective: To understand the association between positive and negative childhood experiences with uncertainty stress in college students. Methods: From March to May 2021, 1 816 college students in Jiangsu and Hubei Province were randomly selected, and an electronic structured questionnaire was used to collect the general characteristics, positive and adverse childhood experience, and uncertainty stress. Logistic regression was used to explore the association between positive and negative childhood experiences with uncertainty stress. Results: The reported rate of uncertainty stress among 1 816 college students was 27.5%( n =500). Logistic regression results showed that the risk of uncertainty stress among students with childhood abuse experience was 2.10 times higher than that of control group( OR=2.10, 95%CI =1.64-2.70). The probability of uncertainty stress in students with high self awareness was 37% of those with low self awareness( OR=0.37, 95%CI =0.24-0.57). The probability of uncertainty stress in students with positive predictable life was 32% of those without( OR=0.32, 95%CI =0.13-0.77). Conclusion College students are vulnerable population for psychological stress. Both positive and adverse childhood experience are associated with the occurrence of uncertainty stress. Early screening for with adverse childhood experiences in adolescents is recommended to protect physical and mental health.

Objective:To explore the values of fat saturation sequence in MRI for juvenile arthritis.Methods:A total of 1 131 cases with juvenile arthritis and 1 601 with symptomatic arthritis were examined by MRI normal T1 weighted imaging (T1WI) and T2 weighted imaging (T2WI)sequence and spectral presaturation attenuatedinversion recovery (SPAIR) T2 fat saturation sequence.All the images were independently evaluated by two senior doctors from the Department of Radiology and the Department of Pediatric Rheumatology and Immunology respectively to confirm the types and degree of pathological changes of joint tissues.Results:Among the subjects,847 patients demonstrated positive in MRI,accounting for 52.9％;409 patients showed positive in normal sequence,accounting for 48.3％;816 patients showed positive in fat saturation sequence,accounting for 96.3％.Joint hydrops accounted for 59.5％.Bone marrow edema accounted for 39.7％.The relevant ratio of bone marrow edema,joint hydrops,thickening of synovium and cartilage injuries in fat saturation sequence were higher than that in normal sequence (P＜0.05).The relevant ratio of bone erosion in normal sequence was higher than that in fat saturation sequence (P＜0.05).However,no significant difference of joint cysts was found between the fat saturation sequence and normal sequence (P＜0.05).Conclusion:Application of fat saturation sequence by MRI to check juvenile arthritis could obviously improve the positive MRI relevant ratio.In addition,the relevant ratio of the early pathological changes of juvenile arthritis (such as bone marrow edema and joint hydrops) was high,which might provide references for the early diagnosis of juvenile arthritis.

Objective To explore the significance of interleukin (IL)-1β and IL-6 in serum of children with hyperuricemia (HUA). Methods 142 children including 71 children with HUA (HUA group) and 71 control children (control group), healthy and inguinal hernia children were selected as control group. 71 HUA children were subdivided into GA (gout attacks) group (n=28) and NGA (non-gout attacks) group (n=43) according to whether they had a history of acute gout attacks, including sudden monoarthritis of rapid onset with intense pain and swelling or without. Enzyme-linked immunosorbent assay was used to measure the level of IL-1β and IL-6 in serum. Results Serum IL-1β and IL-6 levels of HUA children were significantly higher than those of control group (all P<0.05). Serum IL-1β and IL-6 levels of HUA children in GA group were significantly higher than those of NGA group (P<0.05). Serum IL-1β and IL-6 levels of GA group in acute phase was significantly higher than those of HUA children in remission stage、NGA group and control group (P<0.05). Serum IL-1β and IL-6 levels of GA group in remission stage and NGA group was significantly higher than those of control group (P<0.05). There were no significant differences between HUA children in remission stage and NGA group (P>0.05). The serum IL-1β and IL-6 levels of HUA children were positively correlated with WBC, neutrophils, monocytes, uric acid, ESR, CRP, BUN and Cr (all P<0.05), while not correlated with triglyceride, total cholesterol, LDL-C and HDL-C(all P<0.05). Conclusion IL-1β and IL-6 play an important role in the pathogenesis of HUA in children.

To investigate roles of nitric oxide (NO) signal in accumulations of phenolic acids in abscisic.acid (ABA)-induced Salvia miltiorrhiza hairy roots, S. miltiorrhiza hairy roots were treated with different concentrations of sodium nitroprusside (SNP)-an exogenous NO donor, for 6 days, and contents of phenolic acids in the hairy roots are determined. Then with treatment of ABA and NO scavenger (2-(4-carboxy-2-phenyl)-4,4,5,5-tetramethylimidazoline-1- oxyl-3-oxide, c-PTIO) or NO synthase inhibitor (NG-nitro-L-arginine methyl ester, L-NAME), contents of phenolic acids and expression levels of three key genes involved in phenolic acids biosynthesis were detected. Phenolic acids production in S. miltiorrhiza hairy roots was most significantly improved by 100 µmoL/L SNP. Contents of RA and salvianolic acid B increased by 3 and 4 folds. ABA significantly improved transcript levels of PAL (phenylalanine ammonia lyase), TAT (tyrosine aminotransferase) and RAS (rosmarinic acid synthase), and increased phenolic acids accumulations. However, with treatments of ABA+c-PTIO or ABA+L-NAME, accumulations of phenolic acids and expression levels of the three key genes were significantly inhibited. Both NO and ABA can increase accumulations of phenolic acids in S. miltiorrhiza hairy roots. NO signal probably mediates the ABA-induced phenolic acids production.
