Background: Preterm birth is the leading cause of neonatal death, and there are no effective clinical means for the prevention and treatment of spontaneous preterm birth, mainly because the mechanism for labor initiation has not been fully elucidated.
Objective: The effect of enucleation with Zhuyun I Recipe Capsule enema (ZRC) on the maternal-fetal interface microenvironment in SD rats with kidney deficiency and blood stasis.
Methods: In this study, poor endometrial tolerance was induced by hydroxyurea and epinephrine in SD rats with kidney deficiency and blood stasis type of endometrium, and gavage with norethindrone (estradiol) or Bamboo Rhythm No.1 formula. HOXA10 mRNA levels were measured by qPCR. In addition, the expression of IL-6, VEGF, TGF-, and IGFBP-1 in the uterus was detected by IHC and ELISA.
Results: Hydroxyurea- and epinephrine-induced PER was associated with low levels of HOXA10 in the endometrium and reduced levels of IL-6, TGF-, VEGF, and IGFBP-1 in the endometrium. These were abolished by ZRC and Progynova treatment compared to PER rats, resulting in a dramatic increase in the levels of HOXA10 mRNA, IL-6, TGF-, VEGF, and IGFBP-1 proteins.
Conclusions: ZRC improves metaplasticization of endometrial stromal cells and promotes angiogenesis in rats with kidney deficiency and blood stasis. The moderate dose of kidney tonic to promote blood circulation method is superior in promoting angiogenesis, facilitating the establishment and maintenance of pregnancy, limiting trophoblast invasion of metaplasia, reducing miscarriage, and improving pregnancy rate.

PTEN, a tumor suppressor phosphatase, regulates cellular functions by antagonizing the growth promoting PI3K/Akt/mTOR pathway through the dephosphorylation of the second messenger PIP. Many preclinical cellular and animal studies have used PTEN inhibitors to highlight specific disease contexts where acute activation of PI3K/Akt/mTOR pathway might offer therapeutic advantages. In the present study we have re-evaluated first-generation PTEN inhibitors, including established bisperoxo-vanadium complexes (bpVs).

5-Fluorouracil (5-FU) is a DNA analog used in chemotherapy to treat various tumors. However, the clinical use of 5-FU is limited due to its severe adverse effects, particularly its nephrotoxicity. Morin (MRN) is a flavanol found in many different plants, including those in the Moraceae family, and has anti-inflammatory and antioxidant bioactivities.

It is urgent for patients with chronic kidney disease (CKD) to develop a robust and facile therapy for effective control of serum phosphate and reasonable regulation of gut microbiota, which are aiming to prevent cardiovascular calcification and reduce cardiovascular complications. Here, bioinspired by intestinal microstructures, we developed biomimetic wrinkled prebiotic-containing microspheres with enhanced intestinal retention and absorption for reducing hyperphosphatemia and vascular calcification of CKD model rats. The resultant CSM@5 microspheres exhibited favorable phosphate binding capacity in vitro and could effectively reduce serum concentration of phosphorous in vivo.

Impaired bladder compliance secondary to congenital or acquired bladder dysfunction can lead to irreversible kidney damage. This is managed with surgical augmentation utilizing intestinal tissue, which can cause stone formation, infections, and malignant transformation. Co-seeded bone marrow mesenchymal stem cell (MSC)/CD34+ hematopoietic stem cell (HSPC) scaffolds (PRS) have been successful in regenerating bladder tissue.

Background: Diabetic nephropathy (DN), a common complication of type 2 diabetes (T2D), significantly contributes to end-stage kidney disease (ESKD). Despite conventional treatments aimed at slowing disease progression, there is a pressing need for novel therapies. This study evaluates the potential therapeutic impact of adipose tissue derived stromal vascular fraction (SVF) on early diabetic nephrotoxicity in a rat model.
