Objective To investigate the level of urinary protein in type 2 diabetic patients with different glucose excursion and investigation the effect of the glucose excursion on early diabetic nephropathy.Methods Fifty-six type 2 diabetes patients were divided into two groups by the level of glycosylated hemoglobin(HbA1c),good glycemic.Patients in control group with HbA1c ＜ 7.0％ and patients in poor glycemic control group with HbA1c ＜ 7.0％.Microalbuminuria,urine transferring (UTRF),α1-microglobulin (α1-MG) and 32-microglobulin(32-MG) were measured.All the patients were monitored using the continuous glucose monitoring system (CGMS),and mean amplitude of glucose excursions (MAGE) were analyzed.Patients were divided into two groups by MAGE,one group's MAGE was lower than 3.9 mmol/L,and another group's MAGE was higher than 3.9 mmol/L.Urinary proteins were measured and analyzed in the two groups.Results In the poor glycemic control group,the levels of microalbuminuria,UTRF and albunin/ creatinine(A/C) rate were (81.28 ±44.13) mg/L,(4.54 ± 1.54) mg/L and (22.17 ± 14.52) mg/mmol significantly higher than that in the good glycemic control group((21.63 ± 10.16) mg/L,(2.48 ±0.29) mg/L and (2.05 ± 0.76) mg/mmol; t =4.758,5.360,4.805 ; P ＜ 0.05).Fasting C peptide in the poor glycemic control group was (1.01 ± 0.13) ng/ml,significant lower than that in the good glycemic control group ((1.51 ± 0.21) μg/L;t =4.826;P ＜0.05).The levels of A/C rate,α1-MG and β2-MG in the group with MAGE above 3.9 mmol/L significantly higher than those in the group with MAGE below 3.9 mmol/L(t =4.358,8.641,12.702;P ＜ 0.05).Conclusion Both persistent hyperglycemia and blood glucose variability could influent diabetic nephropathy.

Objective To review the diagnosis and treatment of hepatic veno-occlusive disease(HVOD)induced by sedum aizoon in HBsAg positive patients. Methods Clinical data of 35 HBsAg positive cases who took sedum aizoon decoction and developed HVOD were collected, the clinical manifestation, imaging examination, histological examination of liver puncture biopsy, and the outcomes of patients were reviewed. Results Hepatomegaly, liver dysfunction, abdominal effusion and map-like density changes in liver CT scan were observed in 35 patients. Liver biopsy wag performed in 17 patients. In histopathological examination, the swelling and point-like necrosis of liver cells, expansion and congestion of sinus, endothelial swelling, wall thickening, incomplete lumen occlusion of small liver vascular were observed. Map-like density changes in liver CT scan were found in all 17 patients who were diagnosed by histological examination. Fifteen patients presented small amount of ascites within 4 weeks of onset, 13 of whom recovered or improved after treated with low-molecular weight heparin and albumin; while among the remaining 20 patients. only half of them were benefited from the same treatments. Conclusion HVOD can be diagnosed by liver CT scan instead of histological examination; treatment of patients in early stage may improve the outcome.

OBJECTIVETo explore the specific regulative law of electroacupuncture (EA) for the hypothalamus-pituitary-gonad axis.

METHODSThe adult female SD rats were divided into a simulant EA group, Guanyuan (CV 4) group and Neiguan (PC 6) group according to 4 stages of the estrous cycle. Acupuncture was given from 9 : 30 AM to 10 : 00 AM and the brain tissue samples were collected at 15 : 00 PM. GnRH expressions in the nuclei related with genital neuroendocrine in the hypothalamus were investigated with immunohistochemical method.

RESULTS(1) The GnRH expression quantity was different in different estrous cycles in the simulant EA group, with more expression in the proestrus and the estruation; (2) After acupuncture, the GnRH expressions in the medial preoptic area, the arcuate nuclei and the nuclei periventriculares were increased in different stages of the estrous cycle in varying degrees, with the "strong" GnRH expression increased significantly in the diestrus and the metaoestrus in the Guanyuan (CV 4) group.

CONCLUSIONAfter EA, the expression of the GnRH-positive reactant in the medial preoptic area, the arcuate nuclei and the nuclei periventriculares of the hypothalamus significantly increases, with the Guanyuan (CV 4) group better than the Neiguan (PC 6) group, and more obvious expressions in the diestrus and the metaoestrus.
