To investigate the efficacy of Ursolic acid in alleviating neuropathic pain in rats with spinal nerve ligation (SNL), the SNL rat model was surgically induced. Different concentrations of Ursolic acid and manipulated target mitogen-activated protein kinase 1 (MAPK1) were administered to the SNL rats. Fecal samples were collected from each group of rats for 16S rDNA analysis to examine the impact of gut microbiota.

Therefore, the purpose of this study was to analyze sex differences in clinicopathological features and outcomes of MPO-AAV. Patients diagnosed with MPO-AAV in Xiangya Hospital from January 2010 to June 2021 were included in the study and separated into female and male groups.

Hence, we conducted a retrospective study from a single center in China to analyze the clinical and pathological features, and prognosis of DPPs.
Methods: 109 patients with MPO-ANCA-associated vasculitis (MPO-AAV), 20 DPPs and 23 patients diagnosed with anti-GBM disease from a large center in China were included in this study.
There is a consensus that maintenance therapy should be used to prevent relapse of myeloperoxidase-anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (MPO-AAV), but there is a debate about the optimal duration of maintenance therapy. Therefore, the purpose of this study was to determine whether discontinuation of maintenance therapy in MPO-AAV patients who were in long-term stable remission affects relapse, renal survival and patient survival. Seventy-nine patients with MPO-AAV diagnosed at Xiangya hospital from June 2010 to June 2019 who were in stable remission for at least 18 months following maintenance therapy were included.

The systemic immune-inflammation index (SII) is a novel marker of inflammation. The present study was thus performed to explore the association between the SII at diagnosis and inflammatory response and disease activity in Chinese patients with myeloperoxidase (MPO)-AAV.

Evidence is accumulating that there are distinct differences between patients with PR3-AAV and those with MPO-AAV. In the present study, the clinicopathological features and prognosis of patients with PR3-AAV and MPO-AAV from a single center in China were retrospectively analyzed.

However, immune complex (IC) deposition in the glomerulus has been reported in a growing number of studies. Here, we assess the presence of glomerular immune deposits alongside renal outcome in myeloperoxidase (MPO)-ANCA associated glomerulonephritis (MPO-ANCA GN).

However, there are only a few studies looking at NLR in patients with myeloperoxidase (MPO)-anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV). This study was thus undertaken to explore the relationship between NLR at diagnosis with inflammatory response and disease activity among MPO-AAV patients in a single Chinese center.

Current evidence with regard to the risk factors for treatment resistance and relapse remains limited and inconclusive. We aimed to assess the predictors for treatment resistance and relapse in a single-center cohort of Chinese patients with MPO-AAV in this study.

The aim of this study was thus to determine whether the addition of pulse MP to standard induction immunosuppressive therapy in severe myeloperoxidase (MPO) -AAV patients who were on dialysis at onset is associated with an improvement in kidney recovery and patient survival. Furthermore, we analyzed the factors associated with restoration of kidney function and mortality in a single Chinese cohort.

Objective: To study the disease spectrum and causes of death in hospitalized children in an upper first-class hospital in Hunan Province, China.
Methods: The medical records of hospitalized children between 2010 and 2014 in this hospital were collected and analyzed retrospectively.
Results: From 2010 to 2014, the number of hospitalized children increased from 7 303 in 2010 to 10 902 in 2014, and the case fatality rate declined from 0.
Objective: To study the effects of flavonoids of Rhizoma Drynariae on gene level of rats without ovaries (OP) by technology of cDNA array.
Method: The models of rats without ovaries were made After. 24 weeks of treatment, put them to death and sampled 6 ml blood from the abdominal aorta and 4cm spinal cord.
