2.The new treatment target of diabetes: islet β-cell mass
Chinese Journal of Endocrinology and Metabolism 2009;25(3):-
Pancreatic islet β-cell mass is regulated by β-cell replication, nengenesis, apnptosis and cell size. β-cetl mass in diahetic patients is conspicuously less than that in normal subjects. Induction of β-cell regeneration and inhibition of β-cell apoptosis is the new target of diabetes treatment.

Chinese Journal of Pathophysiology 2000;0(12):-
AIM: To explore transdifferentiation potential of Sca-1 + cells from murine fetal liver. METHODS: 2?10 3 of Sca-1 + cells from male murine fetal liver were transfused into female mouse irradiated lethally with ? ray from 60 Co source (10 Gy) via tail vein. Two months later, FISH and immunohistochemistry were used to detect the situation for transdifferentiating of the donor cells (male cells) in tissues of female recipient mouse. RESULTS: The renal tubular epitheliocyte-like and neurocyte-like cells with Y chromosome were found on the sections of renal and brain tissues from female recipient mice. These cells have phenotype characteristics of RCA+/CD - 45 F - 4/80 and NueN +/CD -45 F - 4/80, respectively. CONCLUSION: The evidence is provided for Sca-1 + cells from murine fetal liver to transdifferentiate into both renal and brain tissue cells.
4.Analysis of risk factors for spontaneous bacterial peritonitis in hepatic cirrhosis
Chinese Journal of Primary Medicine and Pharmacy 2011;18(16):2182-2183
ObjectiveTo study the risk factors of spontaneous bacterial peritonitis(SBP) in cirrhotic patients with ascites. MethodsThe clinical data of 186 cirrhotic patients with ascities from February 2005 to March 2010 were retrospectively analyzed were divided into two groups,the one with SBP and the other without SBP. The following factors such as sex, Child-Pugh grade were analyzed with binary logistic regression. ResultsAmong those factors ,3 factors were proved to be risk factors for SBP in cirrhotic patients with ascites by analysis of single and multiple variables. Those were Child-Pugh grade score, serum bilirubin level and ascitic fluid albumin. ConclusionSBP in cirrhotic patients with ascites was affected by many factors. The Child-Pugh grade score, serum bilirubin level and ascitic fluid albumin were independently associated with risk factors of SBP, so it was important to pay attention to those factors in preventing the onset of SBP.

Journal of Third Military Medical University 1988;0(06):-
Young Kunming mice were fed with the food containing mercuric chloride, lithium carbonate, lead acetate or cadmium chloride for 45 days. It was found that these 4 salts of metals could all result in different degrees of functional and structural damages of the kidneys of the mice. In the mercuric chloride and lead acetate groups. the liver and the duodenum were also severely damaged besides the renal damages and the mice suffered a high mortality during the period of taking the toxicants. In the lithium carbonate group, the mortality was also very high but the histological damages of the kidneys were less severe. In the cadmium chloride group, the renal damages were more severe than in the other 3 groups, the mortality of the mice was relatively low, the histology of the heart, the liver and the duodenum was essentially normal, and the renal damages became worse even the toxicant was stopped. It is concluded that cadmium chloride is the agent of choice to establish the mouse model of chronic renal failure.

Four fresh corpses of infant are used in this research. Three-dimensional microvasculatures of the sinoatrial node and atrioventricular node were studied by means of the observation of vascular casts with SEM. The results showed that the vascular bed of the sinoatrial node was consisted of the microvascular networks. It was oval in shape. The central artery penetrated this node, through its longitudinal axis and divided progressively into arterioles and precapillary arterioles and finally, they branched into capillary networks at the superficial part of the node. The postcapillary venules were characterized by draining blood in accordance with area. The microvascular construction of atrioventricular node was an oblate microvascular network in shape. There was a layer of delicate capillary networks at its superficial part. In the depth of the capillary networks, the venous plexus which was thick and sinusoidal in shape was observed through the meshes. The artery of atrioventricular node entered the node from one side of it. In the node, the artery ramified by degrees to periphery into precapillary arterioles, which penetrated venous plexus and connected with capillary networks in the superficial part of the node. There were evidently narrow rings, whick were impression of the muscle sphincters at the origin of thep ostcapillary venules.

Objective To explore the effect of let-7c-1 on the learning and memory of PTZ-induced epileptic rats and its relevant mechanism.Methods A model of temporal lobe epilepsy (TLE) was induced via PTZ kindling in SD male rats.The epileptic rats were divided into epilepsy group,agomir-control group,let-7c-1 agomir group (12 rats for each).Twelve rats were served as a negative control group.The behavior and the expression levesl of let-7c-1,Bcl-2 protein and Caspase3 were evaluated at 28 days following PTZ.Results Compared to the negative group,the escape latency of epilepsy group was prolonged and the crossing times as well as the quadrant total distance in the target were reduced (P<0.05).However,those parameters were not significantly different between the epilepsy group and the agmoir-control group (P>0.05).Compared to the agmoir-control group,the escape latency of let-7c-1 agomir group was prolonged and the crossing times as well as the quadrant total distance in the target were reduced (P< 0.05).The expression levels of let-7c-1 and let-7c-1 were 1.35±0.32 in agmoir-control group and 62.53±21.01 in agomir group (F=50.97,P<0.05).The expression levels of let-7c-1 were higher in let-7c-1 agomir group than in other groups (P<0.05).Compared to the negative group,the expressions of Bcl-2 protein in other groups were decreased (P<0.05) and the Caspase3 protein were increased (P<0.05).Compared to the agomir-control group,the expression of Bcl-2 protein was significantly decreased and the expression of Caspase3 protein was significantly increased in let-7c-1 agomir group (P<0.05).Conclusions The present study shows that let-7c-1 may impair the learning and memory of PTZ-induced epileptic rats through decreasing the Bcl-2 protein and increasing Caspase3 protein in the hippocampus.

AIM: To study the effect of acute renal failure (ARF) on the differentiated frequency of Sca-1+ cells from murine fetal liver in irradiated mice. METHODS: The Sca-1+ cells from murine fetal liver were isolated with magnetic cell sorting (MACS) technique, the sex of which was identified by PCR. The 2?104 Sca-1+ cells were transplanted into a lethally irradiated ([ 60Co], 8 Gy) inbred female mouse. After 8 weeks, these recipient mice were divided to A, B, and C groups at random (A group: irradiated; B group: ARF; C group: ARF and Sca-1+). The mice in B and C groups were induced to ARF with 50% (V/V) glycerin (11.6 mL/kg). 72 hours later, the mice in C group were injected with the fresh prepared Sca-1+ cells again. 8 weeks later, mice were sacrificed, and their kidneys were taken out, fixed and slices were prepared. Fluorescence in situ hybridization (FISH) of renal slices was performed and the pictures of them were taken and analyzed. RESULTS: The cells containing Y chromosome were found in renal slices from the mice in A, B and C groups, which located in epithelial cells of renal tubules, interstitium, glomeruli, and glomerular margin and increased gradually. The double and encircle zone of Y chromosome cells were found in the slices from the mice in B and C groups separately, which was consist of new renal tubules. The differentiation frequency of Sca-1+ cells in kidney in A, B and C groups were (1.65?0.18)%, (8.58?1.34)% and (18.13?1.91)%, respectively, which showed significant difference between former group and later group (P
