Objective To analyze the carbetocin combined with oxytocin for prevention of bleeding after artificial abortion .Methods 110 cases of pregnant women undergoing artificial abortion were randomly divided into observation group and control group.Observation group were treated with carbetocin combined with oxytocin treatment, the control group were treated by oxytocin treatment, the negative blood loss, menstrual recovery changes and curative effect in two groups of patients were compared.Results The total efficiency of the observation group was 96.36%, was significantly higher than the control group 78.18%, the difference was statistically significant (P<0.05), the 24h negative bleeding volume, vaginal bleeding time, menstruation time, first menstrual duration in the observation group were lower than those in control group, the difference was statistically significant (P<0.05).The vaginal bleeding time less than 7d in observation group of patients accounted for 30.91%, was significantly higher than the control group 18.18%; the time of vaginal bleeding >14d accounted for 3.64%, significantly lower than the control group 21.82%, the difference was statistically significant (P<0.05).The vaginal bloodmenstrual volume accounted for more than 9.09%, was lower than 32.73%in the control group, the difference was statistically significant (P<0.05).The sex hormone in two groups of patients before and after the treatment had no significant difference.The progesterone level in observation group was lower than the control group, estradiol level was higher than the control group, the difference was statistically significant (P<0.05), the adverse reaction rate in control group was 12.73% compared with 7.27% in the observation group, the difference was no statistically significant.Conclusion The abortion patients after treated with carbetocin combined with oxytocin treatment can reduce the amount of vaginal bleeding, shorten the bleeding time and menstrual recovery time, safe and reliable curative effect.

OBJECTIVETo explore the anti-inflammatory effect and possible mechanism of Shuang-huang-lian (SHL) microemulsion.

METHODRat model of pleuritis was established by thoracic injecting 0.2 mL of 1% carrageenan. Rats in the treated groups were orally administered with SHL microemulsion prescription 1, 2, and oral liquid, while those in the positive control group were given aspirin. Rats in the normal group and the model group were given equal volume of water. Each groups were given their medicine for successive 6 days. Modeling was performed 30 mins after the 5th day medication. After 12 hrs of modeling, took suction of the pleurorrhea and measured the amount of tumor necrosis factor alpha (TNF-alpha), interleukin-8 (IL-8), prostaglandin E2 (PGE2) and protein (pro).

RESULTCompared with the normal group, all the parameters were higher in model group (TNF-alpha and IL-8 P<0.01, PGE2 and pro P<0.05). While compared with the model group, only the amount of TNF-alpha and PGE2 were lower in all the treated group (P<0.01).

CONCLUSIONBoth SHL microemulsion prescription 1 and 2 have obvious anti-inflammatory effect. The effect might be related to inhibiting the increase of cytokines as TNF-alpha and PGE2, and intervening of the metabolic process of arachidonic acid (AA).

Objective:To investigate the effect of high-dose vitamin B6 on stress-induced liver cell death in rats with severe trauma and its possible mechanism.Methods:Thirty-two male SD rats were selected and divided into sham surgery group, sham surgery+B6 group, trauma group, and trauma+B6 group by using a random number table, with 8 rats in each group. Rat models of severe trauma were established by inducing abdominal wall injury, bilateral femoral fractures, unilateral cranial injury, and withdrawal of 4 ml blood from the femoral artery. The sham surgery+B6 group and trauma+B6 group were treated with saline solution plus high-dose vitamin B6, while the sham surgery group and trauma group with infusion of saline solution only. At 36 hours after injury, rat liver tissues were collected for the following experiments: (1) the genes differentially expressed in the liver tissues of the rats of the trauma group and the trauma+B6 group were screened with next-generation sequencing, followed by an analysis of the possible involvement of cell death pathways; (2) validation was conducted to ascertain whether high-dose vitamin B6 could influence various cell death pathways in the liver cells in the sham surgery group, sham surgery+B6 group, trauma group, and trauma+B6 group: apoptosis was confirmed through terminal-deoxynucleotidyl transferase mediated nick end labeling (TUNEL) staining; necroptosis was verified by mixed lineage kinase domain-like protein (MLKL) immunohistochemical staining; autophagy was examined via transmission electron microscopy; ferroptosis was confirmed by detecting oxidative malondialdehyde (MDA) levels, oxidized glutathione levels, Prussian blue staining with diaminobenzidine (DAB) enhancement, transmission electron microscopy, and immunohistochemical staining for acyl-CoA synthetase long-chain family member 4 (ACSL4); (3) Biological information analyses [Gene Ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG), and Gene Enrichment analysis (GSEA)] were performed for biological processes and signaling pathways represented by liver tissue sequencing results of rats between the trauma group and the trauma+B6 group.Results:(1) In the liver tissues of rats, there were 344 significantly differentially expressed genes between the trauma group and trauma+B6 group, comprising 137 upregulated genes and 207 downregulated genes, of which 18 genes were associated with apoptosis, autophagy, necroptosis, ferroptosis, and pyroptosis. (2) No significant differences were found in TUNEL staining among the sham surgery group, sham surgery+B6 group, trauma group or trauma+B6 group; MLKL protein expression levels in the liver tissues after trauma were improved, of which the trauma+B6 group was lower than that of the trauma group; Electron microscopy showed that autophagic activity in the liver cells were significantly increased after trauma, which was significantly lower of the trauma+B6 group than that of the trauma group; MDA levels in the rat liver tissues were (0.20±0.05)nmol/mg, (0.17±0.07)nmol/mg, (0.69±0.11)nmol/mg and (0.52±0.07)nmol/mg in the sham surgery group, sham surgery+B6 group, trauma group, and trauma+B6 group respectively ( P<0.01), with the trauma group having the highest MDA levels and trauma+B6 group having lower MDA levels than the trauma group; Oxidized glutathione levels in the liver tissues of the four groups were (11.75±2.09)μmol/g, (11.69±1.66)μmol/g, (19.75±3.40)μmol/g, and (14.51±1.46)μmol/g respectively ( P<0.01), with the trauma group having the highest levels and trauma+B6 group having lower levels than the trauma group; Significantly increased iron deposition was observed in the liver tissues after trauma, with lower iron deposition in trauma+B6 group than the trauma group; Electron microscopy revealed significantly lower mitochondrial membrane density in the trauma+B6 group compared to the trauma group. ACSL4 protein expression level was lower in the trauma+B6 group compared to the trauma group; (3) GO, KEGG and GSEA enrichment analyses suggested that high-dose vitamin B6 may enhance cholesterol synthesis metabolism in the liver cells and alleviate oxidative stress to reduce liver cell damage and restore normal liver cell function after trauma. Conclusions:High-dose vitamin B6 attenuates stress-induced liver injury in rats with severe trauma by inhibiting the progression of necroptosis, autophagy and ferroptosis. Its molecular mechanism may be associated with enhanced hepatic cholesterol synthesis metabolism and alleviation of oxidative stress in the liver cells.
