Calcific uremic arteriopathy (CUA), termed calciphylaxis, is a rare but highly fatal clinical syndrome. There is no clearly laboratory diagnostic criteria for CUA. The medium and small arterial calcification and microthrombosis discovered by skin biopsy, radiologic imaging,bone scan and the evidence of activation of the bone morphogenetic protein signal (BMPs) transduction pathway are useful for early diagnosis of this disease. The common therapies (including intravenous sodium thiosulfate (STS) and bisphosphonates, hyperbaric oxygen therapy and other symptomatic supports) are used for the management of wounds, pain, nutrition, dialysis and so on. Controlling the chronic kidney disease-mineral and bone disorder (CKD-MBD) and some complications of dialysis and drugs (such as warfarin, active vitamin D) can prevent CUA. However, CUA patients still have poor prognosis and high mortality. Since some patients progress rapidly, it is of great importance to make early diagnosis and provide effective treatments with multidisciplinary management.

OBJECTIVETo assess left ventricular (LV) geometry, LV diastolic and systolic function in maintenance hemodialysis uremic patients.
METHODSForty uremic patients and forty-five normal subjects were included in this study. LV volume, LV mass index (LVMI), relative wall thickness (RWT), LV mass and diastolic volume ratio (LVM/EDV) were measured. Mitral flow E velocity and A velocity ratio, deceleration time, mitral flow E velocity and mitral annulus Ea velocity ratio (E/Ea), pulmonary vein flow S velocity and D velocity ratio, atrial flow reversal velocity of pulmonary vein flow, mitral inflow propagation velocity, left atrium volume (LAV) and pulmonary artery systolic pressure (PASP) were determined for diastolic function evaluation. LV ejection fraction (LVEF) and single volume (SV) were derived from 3D echocardiography, systolic velocity of mitral valve annulus (Sa) by pulse tissue Doppler imaging (TDI) were used to evaluate systolic function. The time to peak systolic velocity (Ts) and early diastole velocity (Td) of LV 12 segments were measured using TDI. The maximal difference of Ts and Td (Ts-Dif and Td-Dif) were calculated to assess LV systolic and diastolic asynchrony.
RESULTSRWT, LVMI and LVM/EDV were significantly increased in uremic patients. There were 50% concentric, 17.5% eccentric hypertrophy and 17.5%concentric remodeling, respectively in uremic patients. The indices for LV diastolic function (E/Ea, LAV and PASP) were significantly higher in uremic patients than those in control subjects (P < 0.01). About 85% of the diastolic dysfunction in uremic patients presented as impaired relaxation pattern and 32.5% as increased filling pressure. LVEF and SV were similar between uremic patients and control subjects. Sa was significantly lower in uremic group than that in controls (P < 0.05). Ts-Dif was similar between the 2 groups while Td-Dif was significantly higher in uremic patients than control subjects (P < 0.05).
CONCLUSIONLV hypertrophy, LV mass increase and LV diastolic dysfunction were the major characteristic of myocardial injury in uremia patients.

Colonic necrosis is known as a rare complication following the administration of Kayexalate (sodium polystryrene sulfonate) in sorbitol. We report a rare case of colonic mucosal necrosis following Kalimate (calcium polystryrene sulfonate), an analogue of Kayexalate without sorbitol in a 34-yr-old man. He had a history of hypertension and uremia. During the management of intracranial hemorrhage, hyperkalemia developed. Kalimate was administered orally and as an enema suspended in 20% dextrose water to treat hyperkalemia. Two days after administration of Kalimate enema, he had profuse hematochezia, and a sigmoidoscopy showed diffuse colonic mucosal necrosis in the rectum and sigmoid colon. Microscopic examination of random colonic biopsies by two consecutive sigmoidoscopies revealed angulated crystals with a characteristic crystalline mosaic pattern on the ulcerated mucosa, which were consistent with Kayexalate crystals. Hematochezia subsided with conservative treatment after a discontinuance of Kalimate administration.

Wernicke's disease is a condition produced by thiamine deficiency; more than 90% of the cases are observed in chronic alcoholics. Other less frequent conditions associated with Wernicke disease are gastric disorders, prolonged parenteral nutrition, uremia, hemodialysis, hyperemesis gravidarum, prolonged starvation, and AIDS. We report a 41-year-old female patient of Wernicke disease associated with nausea and prolonged parenteral nutrition after chemotherapy of acute promyelocytic leukemia. She has got thiamine replacement therapy and most symptoms were improved. She was discharged after complete remission of leukemia and recovery of normal diet.

We report a case of hemolytic uremic syndrome (HUS) associated with hemorrhagic colitis. A 35-year-old man was admitted to a local hospital because of abdominal pain and watery diarrhea that had developed about 6 hours after taking roast beef. He was treated with intravenous fluids and antibiotics, but watery diarrhea changed to bloody in nature from the next day. He was transferred to our hospital due to progressive ascites and jaundice on his 8th day of illness. Examinations revealed ascites, jaundice, microangiopathic hemolytic anemia, thrombocytopenia and uremia. Sorbitol-negative Escherichia coli was isolated from his stool, which proved as Shiga-like toxin-negative E. coli, serotype O25. His conditions improved markedly after three times of plasmapheresis and intravenous fluid therapy, and the organism was not isolated from the follow-up stool culture.

This study was aimed to investigate coagulation factor VII level in uremic patients with chronic renal failure and to explore theirs influence factors. The plasma levels of coagulation factor VII were detected in 30 uremic patients with chronic renal failure before and after hemodialysis for 1 month, the factor VII activity (FVII:C) was determined by one-stage coagulation method, while activated factor VII (FVIIa) was measured by one-stage coagulation method using recombinant soluble tissue factor, and factor VII antigen was detected by ELISA. The results showed that: (1) The FVIIa, FVII:C and FVIIAg levels in chronic uremic patients before hemodialysis were 4.00 +/- 0.86 microg/L, (148.5 +/- 40.4)% and (99.8 +/- 21.1)% respectively, which were significantly increased, as compared with healthy controls [2.77 +/- 1.02 microg/L, (113.1 +/- 33.0)% and (73.7 +/- 18.3)% respectively, P < 0.05]. (2) After hemodialysis the FVIIa, FVII:C and FVIIAg levels in uremic patients significantly enhanced to 5.56 +/- 1.45 microg/L, (200.8 +/- 68.7)% and (124.1 +/- 19.3)% respectively (P < 0.05). (3) The abnormal increase of coagulation factor VII was positively correlated with levels of blood uria nitrogen and serum creatinine before hemodialysis but not after hemodialysis. It is concluded that the enhanced levels of coagulation factor VII in chronic uremic patients suggested abnormal activated state, herperactivity and elevated production of factor VII which correlated with renal functional injury. The abnormality of factor VII in uremia may be aggravated by hemodialysis. Coagulation factor (FVII) may be a risk factor for cardiovascular events in uremic patients who especially had been accepted long-term hemodialysis.

10.Understanding and Therapeutic Strategies of Chinese Medicine on Gut-Derived Uremic Toxins in Chronic Kidney Disease.
Chinese journal of integrative medicine 2018;24(6):403-405
Chronic kidney disease (CKD) is a major disease that threatens human health. With the progression of CKD, the risk of cardiovascular death increases, which is associated with the elevated levels of uremic toxins (UTs). Representative toxins such as indoxyl sulfate and p-cresyl sulfate are involed in CKD progression and cardiovascular events inseparable from the key role of endothelial dysfunction. The therapeutic strategies of UTs are aimed at signaling pathways that target the levels and damage of toxins in modern medicine. There is a certain relevance between toxins and "turbid toxin" in the theory of Chinese medicine (CM). CM treatments have been demonstrated to reduce the damage of gut-derived toxins to the heart, kidney and blood vessels. Modern medicine still lacks evidence-based therapies, so it is necessary to explore the treatments of CM.
