Objective: To observe the anti-tumor effect of moxibustion with seed-sized moxa cones on Hepa1-6 liver cancer bearing (HLCB) mice and its regulatory mechanism on cell apoptosis.

Methods: A total of 40 male C57BL/6 mice were randomly divided into control, moxibustion, cyclophosphamide (CTX) and moxibustion+CTX groups, with 10 mice in each group. The HLCB model was established by subcutaneous inoculation of Hepa1-6 cancer cells into the right armpit.

Long-term visit-to-visit variability in low-density lipoprotein cholesterol is associated with poor cardiovascular and kidney outcomes in patients with primary nephrotic syndrome.

Purpose: It is unclear whether long-term variability in low-density lipoprotein cholesterol (LDL-C) is associated with clinical outcomes in patients with nephrotic syndrome (NS).

Methods: A large cohort of 1100 patients with primary NS underwent treatment and regular follow-up. Long-term variability in LDL-C was assessed by calculating its weighted standard deviation (w-SD).

The quantifying relationship between the remission duration and the cardiovascular and kidney outcomes in the patients with primary nephrotic syndrome.

Background: Patients with persistent nephrotic-range proteinuria have a high risk of kidney dysfunction and cardiovascular events. Recently, the maintenance of proteinuria remission has been demonstrated to reduce the risk of kidney endpoint. However, the effect of remission duration on cardiovascular outcomes remains unclear.

Effects of hydroxychloroquine on proteinuria in membranous nephropathy.

Ninety-five consecutive patients with pMN diagnosed by kidney biopsy received rituximab and were followed up for >6 months.

Complement activation profile of patients with primary focal segmental glomerulosclerosis.

Background: Studies on adriamycin mice model suggest complement system is activated and together with IgM contributes to the glomerular injury of primary focal segmental glomerulosclerosis (FSGS). We recently reported primary FSGS patients with IgM and C3 deposition showed unfavorable therapeutic responses and worse renal outcomes. Here we examined the plasma and urinary complement profile of patients with primary FSGS, aiming to investigate the complement participation in FSGS pathogenesis.

Complement activation products in the circulation and urine of primary membranous nephropathy.

Background: Complement activation plays a substantial role in the pathogenesis of primary membranous nephropathy (pMN). C5b-9, C3c, MBL, and factor B have been documented in the subepithelial immune deposits. However, the changing of complement activation products in circulation and urine is not clear.

Antibodies against M-Type Phospholipase A2 Receptor May Predict Treatment Response and Outcome in Membranous Nephropathy.

Background: Anti-phospholipase A2 receptor (PLA2R) antibodies are specific to the diagnosis of primary membranous nephropathy (pMN). The prevalence of positive antibodies varies among different cohorts. Still there is discrepancy in regard to the association between antibody levels and clinical courses, and the prognostic value of antibodies to treatment responses and kidney outcomes.

HLA class II alleles differing by a single amino acid associate with clinical phenotype and outcome in patients with primary membranous nephropathy.

Genome-wide associations and HLA genotyping have revealed associations between HLA alleles and susceptibility to primary membranous nephropathy. However, associations with clinical phenotypes and kidney outcome are poorly defined. We previously identified DRB1*1501 and DRB1*0301 as independent risk alleles for primary membranous nephropathy.

Clinical implications of pathological features of primary membranous nephropathy.

Background: The clinical outcome varies considerably in primary membranous nephropathy (pMN). Risk factors for kidney prognosis include ageing, male gender, persistent heavy proteinuria, decreased eGFR at presentation, persistent elevation of anti-PLA2R antibodies, no remission, and so on. It was controversial whether the histopathological features of pMN could predict treatment response and kidney outcome.

Clinical and prognostic significance of glomerular C1q deposits in primary MN.

Background: Although complement activation is believed to be important in mediating PMN, the pathways involved and clinical consequences remain controversial. Many cases of idiopathic or primary membranous nephropathy (PMN) present with subepithelial C1q deposits along with IgG and C3 on glomerular capillary walls but without deposits of IgA or IgM ("full house") by immunofluorescence or any causes of secondary MN. We sought to define the clinical and pathological significance of these C1q deposits in PMN by comparing a variety of clinical parameters, outcomes and other serum and urine factors in patients with and without significant glomerular C1q deposits.

Rituximab for non-responsive idiopathic membranous nephropathy in a Chinese cohort.

Background: Rituximab had been shown to be effective in inducing remission of nephrotic syndrome in patients with idiopathic membranous nephropathy (iMN). This study applied rituximab therapy for 36 non-responsive iMN patients to investigate its effects and safety.

Methods: Thirty-six iMN patients who were non-responsive to prior immunosuppression were enrolled.

Circulating Antibodies against Thrombospondin Type-I Domain-Containing 7A in Chinese Patients with Idiopathic Membranous Nephropathy.

Background And Objectives: Thrombospondin type-I domain-containing 7A (THSD7A) was recently identified as the target antigen in about 10% of patients with M-type phospholipase A2 receptor (PLA2R)-negative membranous nephropathy in European and North American populations. The prevalence of THSD7A in other populations and their clinical associations deserve further clarification.

Design, Setting, Participants, & Measurements: Immunofluorescence assay was performed to investigate anti-THSD7A antibodies in 578 consecutive patients with biopsy-proven idiopathic membranous nephropathy, 114 patients with secondary membranous nephropathy, 64 disease controls, and 20 healthy controls.

MHC Class II Risk Alleles and Amino Acid Residues in Idiopathic Membranous Nephropathy.

Epitopes of phospholipase A2 receptor (PLA2R), the target antigen in idiopathic membranous nephropathy (iMN), must be presented by the HLA-encoded MHC class II molecules to stimulate autoantibody production. A genome-wide association study identified risk alleles at HLA and PLA2R loci, with the top variant rs2187668 within HLA-DQA1 showing a risk effect greater than that of the top variant rs4664308 within PLA2R1. How the HLA risk alleles affect epitope presentation by MHC class II molecules in iMN is unknown.

[Therapeutic application and prospect of Astragalus membranaceus and Angelica sinensis in treating renal microvascular lesions].

It has been known that the renal microvasular lesions could aggravate the progress of glomerular sclerosis and tubulo-interstitial fibrosis in chronic kidney diseases. Modern pharmacological studies indicated that the two traditional Chinese herbs, Astragalus membranaceus and Angelica sinensis, could improve micorvascular lesions through multiple mechanisms, including increasing local renal blood flow to lessen the hypoxic renal injury, promoting the recovery of renal blood flow and glomerular filtration rate after ischemia-reperfusion, modulating the imbalance of vaso-activators such as nitric oxide and angiotensin, increasing the expression of vascular epithelial growth factor and inhibiting the release of the intracellular calcium ion and promoting DNA synthesis in endothelial cells to improve the function of endothelial cells. These evidences suggest that Astragalus membranaceus and Angelica sinensis may retard the progress of renal diseases through the above-mentioned mechanisms.
