Objective:To investigate the efficacy and safety of the Steward Scale(S Scale)and the Modified Aldrete Scale (A Scale) for resuscitation of children undergoing gastrointestinal endoscopy with general anesthesia.Methods:A total of 199 underage children who underwent non-intubated gastrointestinal endoscopy with general anesthesia in Children′s Hospital, Zhejiang University School of Medicine from July to December 2022 were retrospectively included in this study and divided into preschool group (36 cases), low school-age group (75 cases) and high school-age group (88 cases) according to age. S Scale and A Scale were also performed to evaluate the recovery from anesthesia. The vital signs of the children and the time required for reaching the target were recorded, and the scoring efficiency and safety of the two scales were compared.Results:The time required for S Scale to reach the standard (17.50 ± 9.29) min was significantly lower than that of A Scale (20.80 ± 12.61) min, and the difference between the two groups was statistically significant ( t = 2.97, P<0.01). In the low school-age group, oxygen saturation (0.989 ± 0.010) of A Scale was higher than that of S Scale (0.980 ± 0.015), the difference was significant ( t = 2.17, P<0.05). The time required for S Scale to reach the standard was negatively correlated with age ( r = -0.385, P<0.01). There was no significant correlation between the time required for A scale to reach the standard and the children′s age ( r = -0.089, P>0.05). Conclusions:Although Steward Scale is more efficient than modified Aldrete Scale in evaluating anesthesia resuscitation in underage children undergoing gastrointestinal endoscopy with general anesthesia, modified Aldrete Scale is safer than Steward Scale and is more conducive to ensuring the life safety of children.

Objective : To investigate the effects of luteolin on invasion and migration of endometriosis stromal cells and whether its mechanism is related to the regulation of 15-hydroxyprostaglandin dehydrogenase (HPGD) expres- sion． Methods : The endometrial stromal cells HEM15A were divided into control group (cells were cultured in nor- mal medium) ，luteolin group ( cells were treated with different concentrations of luteolin) ，si-HPGD group ( cells were transfected with si-HPGD) ，si-NC group ( cells were transfected with si-NC ) ，luteolin + si-HPGD Group (cells were transfected with si-HPGD and treated with 20 μmol / L luteolin) ，Luteolin + si-NC Group ( cells were transfected with si-NC and treated with 20 μmol / L luteolin) . Real-time quantitative PCR was used to detect mRNA level of HPGD．Cell proliferation was detected by CCK-8 assay，Transwell and scratch assays were used to detect cell invasion and migration．The protein expression of proliferating cell nuclear antigen (PCNA) ，matrix metallopro- teinase (MMP-2) ，MMP-9 and HPGD were detected by Western blot，and the level of prostaglandin E2 ( PGE2) was detected by ELISA. Results : Compared with 0 μmol / L luteolin，luteolin at 20，50 and 100 μmol / L significantly inhibited the proliferation activity of hEM15A cells，and reduced PCNA expression ( all P＜0. 05) ．Compared with the control group，20 μmol / L of luteolin significantly inhibited cell invasion and migration (P ＜0. 05) ，decreased the expressions of MMP-2 and MMP-9 (P＜0. 05) ，and up-regulated the mRNA and protein levels of HPGD (P < 0. 05) ，while inhibited cellular PGE2 level (P＜0. 05) ．Compared with the luteolin group，the luteolin + si-HPGD group increased cell invasion and migration (P ＜0. 05 ) ，increased the expressions of MMP-2 and MMP-9 (P < 0. 05) ． Conclusion Luteolin regulates HPGD / PGE2 signaling pathway to inhibit the invasion and migration of en- dometrial stromal cells.

OBJECTIVE To investigate the effects of medicated serum of Siwutang on autophagy of ovarian granulosa cells （KGN cells） in polycystic ovarian syndrome （PCOS） and its underlying mechanism. METHODS Blank serum and different- concentration medicated serum of Siwutang were prepared by intragastric administration of normal saline and different doses of Siwutang [0.52， 1.04， 2.08 g/（kg·d）] in 3-month-old female SD rats. After screening the intervention concentration of Siwutang medicated serum， KGN cells were divided into control group （without any treatment）， dehydroepiandrosterone （DHEA） group （treated with 50 μmol/L DHEA for 48 h）， blank serum group （treated with 50 μmol/L DHEA for 48 h and with 10% blank serum for 72 h） and medium-concentration of Siwutang medicated serum group （treated with 50 μmol/L DHEA for 48 h and with 10% medium-concentration Siwutang medicated serum for 72 h）. The number of autophagosomes was observed in each group， and protein expressions of pathway-related proteins [fructose-1， 6-bisphosphatase 1 （FBP1），mammalian target of rapamycin （mTOR）， phosphorylated mTOR （p-mTOR）]， autophagy-related proteins [p62， microtubule-associated protein 1 light chain 3 （LC3）] and mRNA expression of FBP1 were also detected. The （transfected） cells were further divided into Siwutang group （treated with 10% medium dose of Siwutang medicated serum for 72 h after 48 h intervention with 50 μmol/L DHEA）， Siwutang+si-NC group [negative control small interfering RNA （siRNA） transfected cells treated with 50 μmol/L DHEA for 48 h， and then with 10% medium-concentration of Siwutang medicated serum for 72 h] and Siwutang+si-FBP1 group （FBP1 siRNA transfected cells treated with 50 μmol/L DHEA for 48 h， and then with 10% medium-concentration Siwutang medicated serum for 72 h）. The effects of knocking down FBP1 on the above-mentioned effects of Siwutang were detected. RESULTS Compared with control group， DHEA group exhibited an increase in the number of autophagosomes， an elevated LC3-Ⅱ/LC3-Ⅰ and p-mTOR/mTOR， as well as increases in protein and mRNA expressions of FBP1， and decreased protein expression of p62 （P＜0.05）. Compared to both DHEA group and blank serum group， the medium-concentration of Siwutang medicated serum group showed a decrease in the number of autophagosomes， a decrease in LC3-Ⅱ/LC3-Ⅰ， and increases in p-mTOR/mTOR， protein expression of p62， protein and mRNA expressions of FBP1 （P＜0.05）. After knocking down FBP1， compared with Siwutang+si-NC group， Siwutang+si-FBP1 group showed a significant decrease in cell viability， protein expression of p62 ， protein and mRNA expressions of FBP1 as well as p-mTOR/mTOR， and an increase in LC3-Ⅱ/LC3-Ⅰ （P＜0.05）. CONCLUSIONS Siwutang can promote the phosphorylation of mTOR protein by up- regulating the protein and mRNA expressions of FBP1 in KGN cells， thus inhibiting autophagy of KGN cells.
