Research on kidney disease in the scriptures / Монголын эм зүй, эм судлал

Introduction@#Kidney disease is common in our country due to the four seasons and harsh climate. This article is discussed about the kidney health, causes, pathology and kidney on the relationship of other organs in traditional medicine.@*Methods@#The study was processed using analysis and synthesis methods.@*Results@#</br>1. The root nature of the five vital organs are included in the yang character organs which hot nature qualities in five elements. However, some of the five vital organs will be under the influence of that place, as they will be located in the place of the “badgan”, in the place of the “mkhris”, and in the place of the “rlung”. </br>2. Kidney disease is usually caused by falling from a height, hit and injured, lifting heavy things, jogging and twisting your back uncomfortably, sit for a long time in a damp place, water events excess, eating too sweets that are heavy and cold qualities. In medical practice, kidney disease is accompanied by heart disease and liver disease.@*Conclusion@#In according to traditional medicine main theory, kidneys are a solid vital organ that generates heat and warms the lower body because of the high blood flow through its, on the other hand they are cold character which are in the place of the “rlung”. The kidneys are functionally closely related to other organs therefore, to get sick the effects of disease on other organs.

Clinical and pathological features in children diagnosed with primary focal segmental glomerulosclerosis after repeated renal biopsy / 中华肾脏病杂志

Objective:To analyze the clinical and pathological characteristics in children diagnosed with primary focal segmental glomerulosclerosis (FSGS) after repeated renal biopsy.Methods:The clinicopathological data of children who ever experienced renal biopsy in Jinling Hospital from January 1, 2000 to December 31, 2020 were retrospectively reviewed. Clinical manifestations, pathological characteristics and treatment responses were analyzed.Results:Of the 34 enrolled patients, there were 22 males and 12 females. The median age of the first renal biopsy was 14 years old (1-18 years old), and the median interval between repeat renal biopsy and first renal biopsy was 6 months (1-151 months). Thirty-one showed nephrotic syndrome, of which 22 had microscopic hematuria, and 4 had elevated serum creatinine. Among the other 3 patients, 2 had hematuria and proteinuria, and 1 had proteinuria. In the first renal biopsy, 16 cases were diagnosed as minimal change disease, 14 cases were diagnosed as mesangial proliferative glomerulonephritis, 2 cases were diagnosed as IgA nephropathy, and 2 cases were diagnosed as IgM nephropathy. All 34 children showed poor responses to hormone and immunosuppressive therapies. The pathological features of the first renal biopsy in some patients were adhesion (2/34), decreased loop podocyte attachment (2/34), peripheral loop extension to the urinary pole (2/34), renal tubular reflux (4/34), capillary thrombosis (2/34) and IgM deposition (12/34).Conclusions:The initial diagnosis of FSGS is difficult, and the lesions are atypical and easily misdiagnosed. The patients have poor responses to hormone and immunosuppressive therapies. For patients with the pathological changes of adhesion, decreased loop podocyte attachment, peripheral loop extension to the urinary pole, renal tubular reflux, capillary thrombosis and IgM deposition, follow-up is required, and if necessary, repeat renal biopsy needs be performed to determine whether it is FSGS.

Effect of TanshinoneⅡA on Renal Tumor Growth Factor-beta 1 and Nuclear Factor-kappa B in Diabetic Nephropathy Rats / 广州中医药大学学报

Objective To observe the effect of tanshinone ⅡA on renal transforming growth factor beta 1 (TGF-β1) and nuclear factor-kappa B (NF-κB) p65 mRNA and protein expression in diabetic nephropathy (DN) rats, thus to evaluate the therapeutic effect and mechanism of tanshinone ⅡA. Methods SD rats were used as the experimental animal. DN rat model was induced with 40 mg/kg of streptozocin ( STZ) . The rats were randomized into normal group, model group, and tanshinone ⅡA ( 10 mg·kg -1·d -1, im) group. On the experimental day 30, we examined the body weight, water in-take volume, 24-hour urine protein, fasting glucose ( Glu) , serum creatinine ( Cr) , blood urea nitrogen ( BUN) , total protein ( TP) and albumin ( Alb). Renal slices after periodic acid Schiff staining ( PAS) were used for the observation of renal pathology. Semi-quantitative reverse transcription polymerase chain reaction ( RT-PCR) was used for the detection of renal TGF-β1 and NF-κB p65 mRNA expression, and Western blotting method was used for the measurement of TGF-β1 and NF-κB p65 protein expression in rats of different groups. Results Compared with the normal group, body weight was decreased, water in-take volume and 24-hour urine protein were increased, serum Glu, Cr, and BUN levels were elevated, TP and Alb levels were decreased, renal pathological damage occurred, and renal TGF-β1 and NF-κB p65 mRNA and protein expressin were promoted in the model group (P<0.05 or P<0.01). Tanshinone ⅡA group had an effect on decreasing water in-take volume, 24-hour urine protein, serum levels of Glu, Cr and Bun, increasing TP and Alb levels, relieving renal pathological damage, and reducing the protein and mRNA expression of renal TGF-β1 and NF-κB p65 ( P<0.05 or P<0.01 compared with the model group). Conclusion Tanshinone ⅡA has protective effect on kidney probably through inhibiting renal TGF-β1 and NF-κB p65 expression in DN rats.

Objective To observe the effects of Yishen Tongluo Decoction (YTD) on the renal mRNA expression of transforming growth factor-β1 ( TGF-β1) and collagen Ⅳ ( ColⅣ) in membranous nephropathy ( MN) rats. Methods SD rats were randomly divided into normal group, model group, benazepril group (in the dosage of 10 mg·kg-1·d-1) , YTD group ( in the dosage of 20 g·kg-1·d-1) . The rats in various groups were given intragastric administration of corresponding agents. At the end of the fourth week, 24-hour urinary protein quantity, albumin ( ALB) , total protein ( TP) , triglyceride ( TG) , total cholesterol ( TC) , blood urea nitrogen ( BUN) , and creatinine (Cr) levels were observed. The mRNA expression levels of TGF-β1 and ColⅣ in renal tissue of rats were detected by immunofluorescence method, electron microscopy and real-time polymerase chain reaction (PCR) method. Results In the model group, urinary protein quantity in rats was increased, serum levels of TP and ALB were significantly lowered, serum levels of TC and TG were significantly increased, renal pathological changes were present, and mRNA expression levels of TGF-β1 and ColIV in renal tissue were up-regulated (P0.05) . Conclusion The therapeutic mechanism of YTD for MN is probably related with the inhibition of mRNA expression of TGF-β1 and ColⅣin renal tissue.

Clinical characteristics and Oxford classification of IgA nephropathy patients with hyperuri-cemia / 临床与实验病理学杂志

Purpose To investigate the clinical characteristics and Oxford classification of IgA nephropathy patients with hyperurice-mia. Methods 151 IgA nephropathy patients confirmed by renal biopsy in 2013 were analyzed retrospectively. The patients were di-vided into the two groups:IgA nephropathy patients with or without hyperuricemia. Morphological changes were evaluated with Oxford classification scoring system and Lee’s grades. A comparative analysis of clinical manifestations and pathological injuries was performed between the two groups. Results Incidence of hyperuricemia in IgA nephropathy patients was 48. 3% and was more common in young men. Hypertension was associated with hyperuricemia. Oxford classification of IgA nephropathy patients with hyperuricemia was pre-dominant M1E0S1T0 and Lee’s grades presented with grade Ⅲ. The outstanding histopathologic features with higher plasma uric acid levels indicated higher tubulointerstitial chronicity, higher glomerular sclerosis ratio, accompanied by a decline in glomerular filtration rate. There was no significant difference of vascular lesions. Conclusions The prevalence of hyperuricemia in IgA nephropathy pa-tients is high. Oxford classification shows IgA nephropathy with hyperuricemia are associated with more severe tubulointerstitial lesions and lower GFR.

Atrazina é um herbicida muito usado em agricultura intensiva e encontrado com alta freqüência em recursos hídricos na região do Pantanal Mato-grossense. Assim, devido aos riscos que a atrazina pode trazer à ictiofauna da região, foi proposta deste trabalho determinar a CL50 da atrazina em alevinos de pacu (Piaractus mesopotamicus). A determinação da CL50 em 96 h em sistema estático, realizada em duplicata, foi conduzida em aquários de vidro com 8 peixes cada, de peso médio de 5,06±0,31g, avaliando-se as seguintes concentrações nominais de atrazina: 0; 13,2; 17,6; 22,0; 26,4; 30,8; 35,2; 39,6 mg L-1, realizando-se também análise comportamental e análise anatomopatológica. Experimento de intoxicação aguda foi realizado em duplicata, nas mesmas condições do anterior, com a concentração da CL50 obtida (28,58 mg L-1), sendo empregados 6 exemplares de peso médio 6,68±0,36g. Amostras hepáticas e mesonéfricas foram colhidas e processadas para análise de microscopia de luz (ML), realizando-se nestas amostras análise semi-quantitativa das alterações encontradas, e para análise de microscopia eletrônica de transmissão (MET). Quanto à avaliação comportamental, foram observados nos grupos tratados: o escurecimento da pigmentação da pele, várias alterações na intensidade do movimento, perda de equilíbrio e presença da ação de boquejamento. Na avaliação anatomopatológica, foram observadas nos grupos tratados: dilatação da região ventral, exoftalmia, protrusão labial, hiperemia no opérculo e em todas as nadadeiras, presença de ar e/ou água no estômago e ascite sanguinolenta...

Exposure to atrazine caused darkening of the skin, alterations in the intensity of movements, loss of balance and an increase in the frequency of gasping. Anatomopathological assessment revealed dilation of the ventral region, exophthalmia, lip protrusion, skin hyperemia in the opercular region and in all fins, the presence of air and/or water in the stomach, and bloody ascites after the herbicide exposition. The histopathological analysis revealed the typical hepatic and renal morphology for the specie, in control group. Several histopathological changes were observed in exposed fish, but the changes most significant were: in liver, the presence of hyaline inclusions in the cytoplasm of hepatocytes, and proximal tubule (PT) degeneration in the kidney. The ultrastructure showed that the atrazine caused several membrane alterations suggestive of oxidative stress and lipid peroxidation...

Objective: This study evaluated the ability of heme oxygenase-1 to prevent or reverse renal fibrosis. Methods: Sprague-dawley male rats were submitted to unilateral ureteral obstruction and divided into groups: non-treated and hemin. Biochemical and histological analyses were performed. We also conducted RT-PCR to verify the expression of heme oxygenase-1, MCP-1, IL1-beta, IL-6, TNF-alfa, COL-I, COL-III, PAI-1 and fibronectin mRNA. Results: heme oxygenase-1 expression significantly increased in treated animals. The non treated group showed significantly higher levels of proteinuria than the Hemin group. The protein/urinary creatinine ratio in obstructed pelvis was also higher in non treated group, which also showed greater albuminuria and higher percentage of fibrosis when compared to the Hemin group. The expression of pro-inflammatory and pro-fibrotic molecules was significantly higher in the non treated group. Conclusions: The treatment induced the expression of heme oxygenase-1, preventing the installation of fibrosis and even limiting its progression.

Nefropatia na infância: estudo morfológico / Nefropathy in childhood: a morphological study

O presente trabalho analisou 992 biópsias de pacientes menores de 16 anos de idade no período de 1980 a 1994. As biópsias de pacientes do sexo feminino representaram 47,08% do total. As indicações clínicas para a biópsia mais frequentemente encontradas foram síndrome nefrótica, síndrome nefrítica e hematúria isolada. As glomerulopatias proliferativas representaram o diagnóstico anatomopatológico mais comum. O diagnóstico morfológico mais freqüentemente associado com a síndrome nefrótica foi a glomeruloesclerose focal e segmentar e aquele mais relacionado à hematúria isolada foi a glomerulopatia proliferativa por IgA.

In the present paper 992 renal biopsies of patients under 16 years of age were analysed in the period of 1980 though 1994. Biopsies of female patients accounted for 47,08% of all biopsies. The most freguent clinical conditions that prompted the biop- sies were nephrotic syndrome, hematuria as a sole symptom and nephritic syndrome. The proliferative glomerulopathies were found to be the most common pathologycal diagnosis. The mor- hological diagnosis most freguently associated with nephrotic syndrome was focal and segmental glomerulosclerosis and the one most often related to hematuria as a sole symptom was IgA proliferative glomerulosclerosis.

A Subacute Toxicological Study on Radix Rhododentri Mollis / 中药新药与临床药理

Sixteen dogs were allocated to 4 groups in equal number and were fed with Rad ix Rhod od end ri Mollis 0.170, 0.345 and 1.420 g/kg for three months respectively, with one group as control. The results showed that Rad ix Rhod od end ri Mollis can cause focal necrosis, edema, ballooning degeneration and fatty degeneration of liver cells. It can also increase the permeability of glomerulus, and cause edema and even ballooning degeneration of renal tubular epithelial cells. Biochemical analysis showed that GPT and BUN apparently increased. Urine analysis showed that qualitative examination of protein, epithelial cells, white and red blood cells were all positive. It is considered that long-term administration of Rad ix Rhod od end ri Mollis can cause functional and structural damage of liver and kidney, and timely suspension of the drug and treatment may render the damage.
