Successful management of postpartum venous thrombosis following splenectomy for traumatic splenic rupture: a case report.

Traumatic splenic rupture is rare in pregnant women; and multiple venous thromboses of the portal vein system, inferior vena cava and ovarian vein after caesarean section and splenectomy for splenic rupture has not been previously reported. This case report describes a case of multiple venous thromboses after caesarean section and splenectomy for traumatic splenic rupture in late pregnancy. A 34-year-old G3P1 female presented with abdominal trauma at 33+1 weeks of gestation. After diagnosis of splenic rupture, she underwent an emergency caesarean section and splenectomy. Multiple venous thromboses developed during the recovery period. The patient eventually recovered after anticoagulation therapy with low-molecular-weight heparin and warfarin. These findings suggest that in patients that have had a caesarean section and a splenectomy, which together might further increase the risk of venous thrombosis, any abdominal pain should be thoroughly investigated and thrombosis should be ruled out, including the possibility of multiple venous thromboses. Anticoagulant therapy could be extended after the surgery.

The SWGEDWGEIW from Soybean Peptides Reduces Insulin Resistance in 3T3-L1 Adipocytes by Activating p-Akt/GLUT4 Signaling Pathway.

Diabetes mellitus, a group of metabolic disorders characterized by persistent hyperglycemia, affects millions of people worldwide and is on the rise. Dietary proteins, from a wide range of food sources, are rich in bioactive peptides with anti-diabetic properties. Notably, the protective mechanism of the single peptide SWGEDWGEIW (TSP) from soybean peptides (SBPs) on insulin resistance of adipocytes in an inflammatory state was investigated by detecting the lipolysis and glucose absorption and utilization of adipocytes. The results showed that different concentrations of TSP (5, 10, 20 µg/mL) intervention can reduce 3T3-L1 adipocytes' insulin resistance induced by inflammatory factors in a dose-dependent manner and increase glucose utilization by 34.2 ± 4.6%, 74.5 ± 5.2%, and 86.7 ± 6.1%, respectively. Thus, TSP can significantly alleviate the lipolysis of adipocytes caused by inflammatory factors. Further mechanism analysis found that inflammatory factors significantly reduced the phosphorylation (p-Akt) of Akt, two critical proteins of glucose metabolism in adipocytes, and the expression of GLUT4 protein downstream, resulting in impaired glucose utilization, while TSP intervention significantly increased the expression of these two proteins. After pretreatment of adipocytes with PI3K inhibitor (LY294002), TSP failed to reduce the inhibition of p-Akt and GLUT4 expression in adipocytes. Meanwhile, the corresponding significant decrease in glucose absorption and the increase in the fat decomposition of adipocytes indicated that TSP reduced 3T3-L1 adipocytes' insulin resistance by specifically activating the p-Akt/GLUT4 signal pathway. Therefore, TSP has the potential to prevent obesity-induced adipose inflammation and insulin resistance.

The most bioactive fraction of stir-fried Radix Paeoniae Alba regulating IL-6/STAT3 signaling pathway in allergic asthma mouse.

ETHNOPHARMACOLOGICAL RELEVANCE: Radix Paeoniae Alba (RPA), a traditional Chinese medicine, has been used frequently in the treatment of asthma. Previous studies demonstrated the dichloromethane fraction of Stir-Frying RPA (FDCM) enhanced the effect of anti-allergic asthma compared with the dichloromethane fraction of RPA (DCM). AIM OF THE STUDY: The significant increasing of Paeoniflorin (PF), ethyl gallate (EG), 1,2,3,4,6-pentagalloylglucose (PGG) had been observed in FDCM. This study aimed to investigate the effects and mechanisms of these compounds from FDCM in ovalbumin (OVA)-induced allergic asthma mouse model. MATERIALS AND METHODS: The significant difference contents compounds fraction (FB-40) and other fractions in FDCM were enriched by Medium Pressure Liquid Chromatography (MPLC). The pharmacodynamics was verified among all fractions in OVA-induced allergic asthma mice. Moreover, the drug dose dependence of FB-40 (0.42 mg/kg, 0.21 mg/kg, and 0.07 mg/kg), which were the most active fraction from FDCM for anti-allergic asthma, was explored. The expression of IL-6, p-STAT3, and STAT3 was analyzed by Western blot analysis. In addition, the main components of FB-40 were identified by UPLC with standards. Finally, the anti-inflammatory effects of the main components from FB-40 were detected by LPS-stimulated BEAS-2B cells using an Elisa assay. RESULTS: The results showed that FB-40 was the most active fraction from FDCM, which could significantly improve the lung tissue pathological condition, and decrease the number of inflammatory cells in bronchoalveolar lavage fluid (BALF). It had greater pharmacological activity than its main component PF. FB-40 also showed dose dependence and regulated the IL-6/STAT3 signaling pathway in allergic asthma mice. Besides, PF, Albiflorin (AF), PGG, EG, and 1,2,3,6-Tetra-O-galloyl-ß-D-glucose (TGG) from FB-40 were identified by UPLC with the standard. At last, in the LPS-induced BEAS-2B cell experiments, EG, PGG, 1,2,3,6-Tetra-O-galloyl-ß-D-glucose (TGG) showed stronger inhibiting activities of cytokine than the monoterpenoid glycosides (PF and AF). CONCLUSION: The research proved that FB-40 was an active fraction in FDCM, which regulates IL-6/STAT3 Signaling Pathway to ameliorate allergic asthma. Gallic acids including TGG and PGG, and EG also play a role in the treatment of allergic asthma in FB-40.

C21 steroidal glycosides from Cynanchum taihangense.

Two new C21 steroidal glycosides, cynataihosides E (1) and F (2), together with a known one, sublanceoside H2 (3), were isolated from Cynanchum taihangense. The aglycone of cynataihoside F (2) was also a new compound. Their structures were elucidated on the basis of NMR spectroscopic data, HR-ESI-MS analysis, and chemical evidence. Their cytotoxic activities against three human tumor cell lines (HL-60, THP1, and Caco2) were reported.

α-Pyrone derivatives with cytotoxic activities, from the endophytic fungus Phoma sp. YN02-P-3.

Four new α-pyrone derivatives phomones C-F (1-4) together with four known compounds (5-8) were isolated from the endophytic fungus Phoma sp. YN02-P-3. Compound 1 is the first example of 6-α,ß-unsaturated ester-2-pyrone dimers via intermolecular symmetrical [2+2] cycloaddition. The chemical structures of these compounds were determined from spectroscopic data (1D/2D NMR, MS and IR). The acetylated product (9) of 1 along with compounds 1-8 were then tested for their cytotoxicity against HL-60, PC-3 and HCT-116 cell lines. Compounds 2, 3, 5 and 9 with acetyl groups showed significant inhibitory activities against the three cell lines with IC50 values in the range 0.52-9.85µM. while compounds 1, 4 and 6-8 that possess no acetyl group showed no inhibitory activity (IC50>50µM), indicating that the acetyl group at 10- or 12- are essential for their cytotoxic activities. The structure-activity relationships of these phomones were also reported.

[Effects of modified longdan xiegan decoction on hyperandrogenism in patients with polycystic ovary syndrome of stagnant fire in Gan channel type].

OBJECTIVE: To observe the therapeutic effect of modified Longdan Xiegan Decoction (LXD) on hyperandrogenism in patients with polycystic ovary syndrome (POS) of stagnant fire in Gan channel type. METHODS: Forty-eight patients were divided into two groups: the LXD group (25 cases) treated with LXI) for 3 months, and the Diane-35 group (23 cases) with Diane-35. Condition of menstruation, acne, hairiness were observed, basal body temperature (BBT) was measured, and the serum levels of luteinizing hormone (LH), follicle-stimulating hormone (FSH), prolactin (PRL), free testosterone (FT), and androstenedione (A) were detected before and after 3 months' treatment. Meanwhile, adverse reaction was observed. RESULTS: After treatment, the condition of menstrual disorder, acne and single-phase BBT were improved significantly, and serum levels of LH, LH/FSH, FT and A decreased in both groups (P < 0.05), showed insignificant difference between them (P > 0.05). The PRL level dropped in the LXD group (P < 0.05), which significantly lower than that in the Diane-35 group (P < 0.05). There were 3 cases with adverse reaction of irregular colporrhagia and 5 cases with nausea and vomiting in the Diane-35 group, while no adverse reaction in the LXD group occurred. CONCLUSION: Modified LXD could significantly improve the condition in hyperandrogenism patients with POS of stagnant fire in Gan channel type.
