ABSTRACT
OBJECTIVES@#To study the effect of somatostatin on postoperative gastrointestinal function and stress level in children with acute abdomen.@*METHODS@#A total of 102 children with acute abdomen who underwent surgery in Xuzhou Children's Hospital from August 2019 to June 2021 were enrolled as subjects and were randomly divided into an observation group and a control group, with 51 children in each group. The children in the control group were given conventional treatment such as hemostasis and anti-infective therapy after surgery, and those in the observation group were given somatostatin in addition to conventional treatment. Peripheral blood samples were collected from both groups before surgery and on days 1 and 5 after surgery. The two groups were compared in terms of the serum levels of endothelin-1 (ET-1), adrenocorticotropic hormone (ACTH), cortisol, gastrin, and motilin, postoperative recovery, and the incidence rate of complications.@*RESULTS@#There was no significant difference in the serum levels of ET-1, ACTH, cortisol, gastrin, and motilin between the two groups before surgery (P>0.05). Compared with the control group, the observation group had significantly lower serum levels of ET-1, ACTH, and cortisol on days 1 and 5 after surgery (P<0.05) and significantly higher levels of motilin and gastrin on day 5 after surgery (P<0.05). Compared with the control group, the observation group had significantly shorter time to first passage of flatus, first bowel sounds, and first defecation after surgery, as well as a significantly shorter length of hospital stay (P<0.05). The incidence rate of complications in the observation group was significantly lower than that in the control group (6% vs 24%, P<0.05).@*CONCLUSIONS@#In children with acute abdomen, somatostatin can significantly reduce postoperative stress response, improve gastrointestinal function, and reduce the incidence rate of complications, thereby helping to achieve a good prognosis.

Objective:To observe effect of ginsenoside Rh2 (GRh2) on the invasion and migration of colon cancer resistant cells HCT116/L-OHP and its specific mechanism. Method:Cell counting kit-8 (CCK-8) assay was used to detect the inhibitory effect of different concentrations of GRh2 (0, 2.5, 5, 10, 20, 40 mg·L-1) on HCT116/L-OHP cell proliferation, scratch assay, Transwell assay and adhesion assay were used to detect the effects of GRh2 (0, 2.5, 5, 10 mg·L-1) on cell migration, invasion and adhesion. The protein expression levels of E-cadherin and matrix metalloproteinase-9(MMP-9) were examined by Western blot. Result:Compared with control group, GRh2(5, 10, 20, 40 mg·L-1) significantly inhibited the proliferation of HCT116/L-OHP cells in a dose-dependent manner(PP2 group (5, 10 mg·L-1) was significantly decreased (PP2 group was significantly decreased (PP2 group was significantly reduced (PP2 (10, 20, 30 mg·L-1) promoted E-cadherin protein expression (PPPConclusion:GRh2 can significantly inhibit the invasion and migration of HCT116/L-OHP in colon cancer cells, and its potential mechanism may be related to the promotion of E-cadherin and the inhibition of MMP-9 expression in a dose-dependent manner.
ABSTRACT
Objective To observe the effect of ginsenoside Rh2 (G-Rh2) on the proliferation, cell cycle and chemotherapy sensitivity of human gastric cancer cell line SGC7901/ADR. Methods MTT assay was used to detected the effects of G-Rh2 and adriamycin (ADR) on the proliferation of drug-resistant SGC7901/ADR cells and to calculate the reversal fold (RF). Flow cytometry was selected to detect The effects of G-Rh2 on cell cycle. the effects of G-Rh2 on the expression of P-gp and Bcl-2 proteins in drug-resistant SGC7901/ADR cells was detected by Western blotting. Results Compared with the IC50 value (54.52 μmol/L) after the ADR single drug treatment, the IC50 value (30.14 μmol/L) of the cells treated with G-Rh2 and ADR decreased significantly, and RF was 1.81. G-Rh2 combined with ADR arrested the cell cycle in G2/M phase and significantly decreased the protein expression of P-gp and Bcl-2(P < 0.05). Conclusion G-Rh2 combined with ADR could increase the chemosensitivity of SGC7901/ADR cells, which may inhibit the proliferation of gastric cancer cells by blocking cell cycle and increasing apoptosis.
ABSTRACT
Aim To explore the effects of prenatal caf-feine exposure (PCE) on fetal renal growth retardation and corticosterone on the gene expression of metanephric mesenchyme stem cells.Methods Pregnant Wistar rats were administered with caffeine (30,120 mg ·kg-1) from gestational day 9 to 20.Female fetal kidney samples were collected for morphological observation and gene expression examination.The metanephric mesenchyme stem cells were harvested for cell culture,and renal related genes were detected after the treatment of corticosterone with different concentrations (250,500,1 000 μg · L-1) for 24 hours.Results Compared with the control group,the fetal kidneys in the PCE group displayed an enlarged Bowman's space and a shrunken glomerular tuft,accompanied with the repression of the gene expression of glial-cell-line-derived neurotrophic factor/tyrosine kinase receptor (GDNF/c-Ret) signaling pathway.The GDNF/c-Ret signaling pathway and angiotensin Ⅱ receptor type 1 (AT1R)/AT2R expression of metanephric mesenchyme stem cells also decreased in corticosterone groups.Conclusions PCE may induce dysplasia of female fetal kidneys.The potential mechanism is related to the repression of the gene expression of AT1R/AT2R and GDNF/c-Ret signaling pathway by PCE mediated by corticosterone in utero.
