Tripterygium wilfordii Hook. f. (TwHF) is a Chinese botanical drug containing a large number of metabolites. The discovered and recognized anti-inflammatory and immune-regulating effects have made it attract more and more attentions in trials and clinical researches. The extraction and processing of TwHF for pharmaceuticals is a manifestation of the role of traditional Chinese medicine. However, TwHF is toxic. Optimization of TwHF preparations has become a requirement for the development of TwHF pharmaceuticals. Our article introduces the main preparations of TwHF on the Chinese market and their characteristics. In particular, we summarize the clinical applications and influential mechanisms of TwHF and its preparations in kidney diseases. Considering that nephropathy is closely related to immune inflammation and TwHF is a botanical drug with a high number of metabolites, the application of TwHF in kidney diseases may be much more complicated. By revealing the role and mechanisms of TwHF in kidney diseases, this study aims to provide more insights to basic and clinical studies about nephropathy.
With the increasing prevalence and mortality, chronic kidney disease (CKD) has become a world public health problem. As the primary pathological manifestation in CKD, renal fibrosis is often used as a critical target for the treatment of CKD and inhibits the progression of CKD to end-stage renal disease (ESRD). As a potential drug, natural products have been confirmed to have the potential as a routine or supplementary therapy for chronic kidney disease, which may target renal fibrosis and act through various pharmacological activities such as anti-inflammatory and anti-oxidation of natural products. This article briefly introduces the pathological mechanism of renal fibrosis and systematically summarizes the latest research on the treatment of renal fibrosis with natural products of Chinese herbal medicines.
Background:
The transversus abdominis plane (TAP) block is commonly used in surgical practice for postoperative analgesia in abdominal surgery. However, numerous studies have demonstrated that TAP block is also suitable for intraoperative anesthesia of peritoneal dialysis catheter (PDC) insertion, although its efficacy and safety are still controversial. Local anesthetic infiltration (LAI) is currently the most general anesthesia strategy for PDC insertion. Consequently, we conducted this systematic review and meta-analysis to identify which anesthesia strategy is better between TAP block and LAI.
Methods:
A systematic and comprehensive search was conducted on 5 databases, retrieving published and registered randomized controlled trials as of March 10, 2022, comparing the anesthesia effects of TAP block and LAI. The primary outcomes are the visual analogue scale (VAS) pain score of patients at various time points in the surgery. The secondary outcomes are the VAS pain score at rest at 2 and 24 hours postoperatively, intraoperative rescue anesthesia, general anesthesia switching rate, and PD-related complications.
Results:
There were 9 trials with 432 patients identified. TAP block was more effective than LAI at reducing intraoperative and postoperative VAS pain scores in patients. Compared to LAI, TAP block significantly reduces the dosage of anesthetics used to rescue anesthesia during surgery, the general anesthesia switching rate, and the incidence of postoperative PD-related complications in patients.
Conclusions:
Our systematic review and meta-analysis proved that TAP block could be used as the primary anesthetic technique for PDC insertion, with superior anesthetic effects to LAI.
Encapsulating peritoneal sclerosis (EPS) is an uncommon and harmful complication which may cause destructive outcomes. Matrix metalloproteinase-2 (MMP-2) as a protease can reduce constituents of the extracellular matrix and play a crucial role in the progression of EPS. As a new biomarker, MMP-2 may improve the detection rate of EPS patients in clinical work. In this review, we summarize the recent study of MMP-2 in different etiologies and the assessment of its application value and draw attention to its future directions.
