With the development of various laboratory testing techniques such as serum calcium and parathyroid hormone (PTH) , a large number of asymptomatic or normocalcemic primary hyperparathyroidism (PHPT) can be diagnosed early. PHPT has become the third most common endocrine disease affecting human health. Currently, most PHPT, especially normocalcemic primary hyperparathyroidism, are not primary diseases and may be related to vitamin D deficiency/insufficiency and/or insufficient calcium supplementation. That is, the relative hypocalcemia caused by long-term vitamin D deficiency/insufficiency and/or insufficient calcium supplementation leads to parathyroid hyperfunction, stimulates parathyroid hyperplasia, and secretes excessive parathyroid hormone to compensate for the regulation of calcium and phosphorus balance. When it is in the initial reversible stage, it can be cured by internal medicine; if it progresses freely, long-term hypocalcemia stimulation will lead to excessive parathyroid hyperplasia and even tumor occurrence with the formation of so-called PHPT and parathyroidectomy has to be performed. Therefore, routine screening of bone mineral density, calcium, magnesium, phosphours, 25-hydroxyvitamin D, parathyroid hormone and other bone metabolism indicators in the physical examination of general population is beneficial to the prevention and treatment of bone metabolism diseases, urinary stones and hyperparathyroidism. At the same time, attention should be paid to identifying the stage of prehyperparathyroidism in which vitamin D deficiency/insufficiency and insufficient calcium supplementation will stimulate parathyroid hyperfunction. Active intervention on prehyperparathyroidism is an effective way to avoid the development of primary hyperparathyroidism.

OBJECTIVETo explore the mechanism of 'erythroblast island (EI)' formation in the bone marrow of patients with immun-related hemocytopenia (IRP).

METHODSThe category of BM-auto antibody (au Ab) in 48 patients with IRP was detected with FCM. The BM-au Ab in the 'EI' of these cases were explored with immuonhistofluorescence (IF). Clinical and laboratory characteristics of these cases were also analyzed retrospectively.

RESULTSIgG could be detected in the 'EI' on the BM smear of 14 cases (29.17%), BM-au Ab mainly deposited at the edge/membranes between macrophage and erythroblasts rather than cyto plasm. Positive reaction were seen in all the cases with GlycoAIgG. The red blood cell count [(1.8 ± 0.5) × 10(12)/L] and hemoglobin level [(59.6 ± 16.2)g/L] were significantly lower than that in the IF(-) group [(2.5 ± 0.9) × 10(12)/L and (83.4 ± 25.0) g/L] (P < 0.05). The percentage of reticulocyte [(2.0 ± 0.8)%], serum level of IBIL [(9.4 ± 4.7) µmol/L], percentage of erythroblats in sternum BM (0.441 ± 0.139) and response rate to therapy (85.7%) in IF(+) group were significantly higher than that in IF(-)group [(1.3 ± 1.0)%, (6.6 ± 6.7)µmol/L, 0.298 ± 0.082, 61.3%, respectively] (P < 0.05).

CONCLUSIONMacrophage was connected with erythroblasts through autologous IgG in the 'EI's of some patients with IRP. 'EI' were the places where macrophages devoured and destroyed erythroblasts rather than erythroid development and differentiation. The pathogenetic mechanism of IRP might be associated with macrophages phagocytosing and destroying BM hematopoietic cells.

OBJECTIVETo explore the possible mechanism of lipid deposition induced by interferon-gamma (IFN-gamma).

METHODSThe mouse mesangial cells (MMC) were randomly divided into control group, stimulation group, stimulation + control vector group (sh-HMGB1) and stimulation+ specific sh-vector group (sh-SREBP-1). RT-PCR was used to detect the expression of HMGB1, SREBP-1 and fatty acid synthetase (FAS) mRNA; the protein expression was determined by Western blot.

RESULTSThe Oil Red O staining revealed that the mouse mesangial cells showed significant lipid droplet in IFN-gamma group. IFN-gamma up-regulated the expression of HMGB1, SREBP-1, FAS mRNA and protein time-dependently; Transfection of MMC with HMGB1 siRNA resulted in the suppression of SREBP-1, FAS protein levels induced by IFN-gamma, following with decrease of lipid deposition. Stimulation with HMGB1 markedly induced expression of SREBP-1, FAS expression and peaked at 8 h, decreased at 12 h compared with that at 8 h. Sh-SREBP-1 decreased the lipid deposition induced by HMGB1 in MMC.

CONCLUSIONIFN-gamma might induce lipid deposition in mouse mesangial cells partly by up-regulating the expression of HMGB1/SREBP-1/FAS.

OBJECTIVETo search for the best method for increasing clinical therapeutic effect on primary abnormality of sperm.

METHODSOne hundred and sixty-eight cases of infertility were randomly divided into a treatment group of 85 cases and a control group of 83 cases. The treatment group were treated with needle-picking at bilateral Shengzhi points, Dicong Shenjing points and L2 Shenjing points as main. The control group were treated with oral administration of Wuzi Yanzong Pills [symbol: see text]. Their therapeutic effects were observed in 3 hospitals.

RESULTSThe total effective rate of 83.5% and the pregnancy rate of the patient's wife of 78.8% in the treatment group, and corresponding figures were 54.2% and 43.4% in the control group, with a very significant difference between the two groups (P < 0.01); and reproductive hormones improved significantly after treatment in the two groups (P < 0.01); after treatment, superoxide dismulase (SOD) activity and Zn content in semen were elevated and cadmium level decreased significantly in the treatment group (P < 0.05).

CONCLUSIONNeedle picking therapy can significantly improve and regulate endocrine function, increase quality of semen and elevate pregnancy rate of the patient's wife for the patient of primary abnormal sperm.
