By study calcium - phosphorus bilan and concentration of PTH in 173 patients with chronic renal failure in different stages showed that: Hyperphosphoremia is very common and this is an important symptom of disorders calcium - phosphorus bilan. This occurs from stage II of CRF (moderate renal failure) and becomes severe in ESRD. Concentration of PTH is really high in ESRD but it's also elevated in stages II and IIIa. The rate of elevated - PTH is 48.6% for all of studied patients.

Blood levels of phosphorus and calcium were quantified in 151 subjects including 30 healthy subjects in control group, and 121 patients of chronical kidney failure of the stage I-IV and the age ranged from 18 to 50. Results demonstrated a reduce of kidney failure of the stage I-II in comparing with control, leading to secondary hyperparathyroid and a hypertrophy of parathyroid gland. The more kidney failure, the higher level of blood calcium, this is an important factor of dystrophy of bone in the patient

OBJECTIVE: To determine effects of the serum levels of phosphorus, calcium and magnesium on patients with type 2 diabetes mellitus.
 METHODS: A total of 244 hospitalized patients were enrolled from 2014 to 2015, and they were assigned into a type 2 diabetic group (n=162) and control group (n=82). The serum levels of phosphorus, calcium and magnesium were determined. The correlations between blood levels of glucose and the serum levels of phosphorus, calcium or magnesium were analyzed. 
 RESULTS: The serum level of phosphate in type 2 diabetic group was significantly lower than that in the control group (P<0.05). There was no significant difference in the level of serum calcium and magnesium between the two groups. In the type 2 diabetic group, there was no significant correlation between the level of blood glucose and the serum level of phosphorus, calcium or magnesium. In the control group, the blood glucose and serum levels of phosphorus were positively correlated (r=0.226, P=0.042), but there was no significant correlation between the level of blood glucose and the serum level of calcium or magnesium.
 CONCLUSION Serum level of phosphorus is obviously decreased in type 2 diabetes patients, indicating that they may have a disorder in phosphorus metabolism.

AIMTo investigate the effects of testosterone on bone mineral density (BMD), plasma levels of sex hormone and calcium, phosphorus, and parathyroid hormone (PTH).

METHODSThirty 10 week old male rabbits were randomized into sham operated (SH), orchiectomized (ORX) and testosterone undecanoate replacement (TU) group. TU rabbits were injected with testosterone undecanoate in 10 orchiectomized rabbits and the remaining SH and ORX rabbits, vehicle only 20 weeks after initiation of the experiment, bone mineral density was measured with dual-energy X-ray bone densitometer. Blood was collected for determination of serum levels of total testosterone, estradiol, calcium, magnesium, phosphorus and alkaline phosphatase (AKP).

RESULTSThe serum levels of total testosterone and femoral neck BMD decreased, serum levels of calcium, magnesium and AKP increased significantly in ORX rabbits, testosterone improved femoral neck BMD and decreased serum levels of calcium, magnesium and AKP significantly in TU rabbits.

CONCLUSIONThe results of the present study indicate that ORX decrease serum testosterone and BMD, exogenous testosterone treatment can prevent osteoporosis in ORX rabbits.

BACKGROUNDWith the increase in hemodialysis (HD) patients, the blood dialysis patient's quality of life (QoL) and long-term survival are still a challenge for clinicians. Recent studies have found that most of the HD patients have sleep disorders, which have a certain correlation with long-term survival and QoL. But there are few studies of Chinese in this field. This study aimed to investigate whether increasing the dialysis dose can improve sleep quality, so we treated HD patients on long intermittent hemodialysis (LIHD).

METHODSForty patients who were treated by conventional HD at the Beijing Friendship Hospital Blood Purification Center were offered the option of LIHD. The patients' laboratory data, medication use, and questionnaire answers were analyzed. Conventional HD was delivered thrice weekly with 4 hours per treatment, and LIHD was delivered thrice weekly with 8 hours per treatment. The study lasted 6 months. Questionnaires included sleep quality survey and QoL SF-36; the former includes the Athens Insomnia Scale, Pittsburgh Sleep Quality Index (PSQI), and Epworth Sleepiness Scale (ESS).

RESULTSAfter conversion to LIHD the dialysis efficiency (Kt/V) significantly increased than before (P < 0.05) and clearance rate of urea nitrogen also increased from 67 to 78% (P < 0.01). After conversion, median values for Hb increased from 108.95 to 126.55 g/L (P < 0.01); albumin increased from 38.85 to 40.05 g/L (P < 0.01). Phosphorus decreased from 2.69 to 1.54 mmol/L (P < 0.01), but there was no alteration in blood calcium; phosphorus and calcium-phosphate product levels were under more control, but parathyroid hormone (iPTH) level did not change after conversion to LIHD. After conversion, blood pressure (BP) was better controlled than before and the mean number of antihypertensive drugs prescribed declined from 2.9 to 0.5 (P < 0.01). There was a significant reduction in the use of erythropoietin-stimulating agent of 5250 U/w (P < 0.01). Sleep quality significantly improved in the 2 months after conversion to LIHD, and the PSQI score decreased from 10.80 to 5.45 and the ESS score decreased from 12.05 to 5.30 (P < 0.01). However, sleep quality started to decline after 2 months on LIHD. QoL SF-36 score increased from 410.92 to 592.53 (P < 0.01).

CONCLUSIONLIHD offers an effective improvement in dialysis adequacy for Chinese maintenance HD patients, but it improves sleep quality only briefly which may be related to loss of serum calcium and parathyroid dysfunction.
