Journal of Kunming Medical University 1989;0(01):-
The serum lipids and lipoproteins in 15 type Ⅱ nephrotic syndrome were studied and compared with 20 health controls. The serum TC, TG, LDL-C were significantly increased. There were the inverse correlation between serum TC, TG, LDL-C and albumin and the week positive corre ation between serum lipids, lipoproteins and creatinine. These suggested that there be the wide abnormalities of lipids and lipoproteins in type Ⅱ nephrotic syndrome which may be risk factors of cardiovascular disease and progressive renal diseases.
3.Effects of the indoleamine 2,3- dioxygenase- initiated L- tryptophan metabolism in organ transplantation
International Journal of Surgery 2012;39(5):339-342
Tryptophan is the essential amino acid in the growth of cell.Indoleamine 2,3-dioxygenase is the rate-limiting enzyme in the catabolism of tryptophan along the kynurenine pathway.Indoleamine 2,3-dioxygenase enzyme mainly promotes tryptophan consumption of local micro-environment,causing tryptophan lack,thus inhibiting proliferation and activation of T cell.Tryptophan-derived catabolites suppress allogeneic T-cell proliferation (kynurenine,3-hydroxykynurenine,and 3-hydroxyanthranilate).Indoleamine 2,3-dioxygenase dendritic cells may interact with regulatory T cells forming an immunomodulatory network to promote immune tolerance induction.Though the immune regulation mechanism of the indoleamine 2,3-dioxygenase-initiated L-tryptophan in transplantation remains unclear,Numerous researches indicate that its role of tolerance induction in transplantation will be significant.
4.Therapeutic value and heterogeneity of zinc supplementation for treating diarrhea in children
International Journal of Pediatrics 2011;38(6):592-594
Zinc supplementation can reduce the mean duration,the recurrence rate and mortality of diarrhea.Nonetheless,it has no effect on stool frequency or stool output.Zinc supplementation results in different effort for the difference of the duration of diarrhea,pathogens,zinc type and doses of zinc,and shows no effect in infants younger than 6 months.Using iron as a co-intervention can reduce the effect of zinc,but vitamin A or ORS have a synergistic effect with the meeting.Average baseline zinc levels did not contribute to variations in the effect size.Zinc supplements are unlikely to improve compliance with the treatment for diarrheal disease.Longer course,zinc alone,malnutrition,diarrhea,breast-feeding children are prone to vomiting after oral administration of zinc.

7.Effect of transforming growth factor-beta 1 on stromal cell-derived factor 1 expression in rat renal tubular epithelial cells
Chinese Journal of Tissue Engineering Research 2007;0(11):-
AIM: It has been proved that transforming growth factor-?1 (TGF-?1) has a close correlation with kidney fibrosis. This study investigated the effects of TGF-?1 on stromal cell-derived factor 1 (SDF-1) in rat renal tubular epithelial cells (NRK52E). METHODS: The experiment was carried out in the Division of Molecular Neurobiology, State Key Laboratory of Biotherapy, Sichuan University from March 2006 to May 2007. ①Rat renal tubular epithelial cells (NRK-52E, Monash Medical Center, Australia) were divided into normal control group, which were not treated with TGF-?1 (Cytola), and experimental group, which were subdivided into time-dependent groups: NRK-52E cells were incubated with TGF-?1 at the same concentration (2 ?g/L) for 6, 12, and 24 hours, and dose-dependent groups: NRK-52E cells were treated with TGF-?1 at different concentrations (2, 5, and 10 ?g/L) for 24 hours. ②The semi-quantitative calculation of SDF-1 protein expression in the cells treated with TGF-?1 at the concentration of 2 ?g/L for different time was accessed by immunocytochemistry to find the best time point. Then the variances of the mRNA and protein expression level in cells treated with TGF-?1 at different concentrations for 24 hours were detected by RT-PCR and Western-Blotting. RESULTS: ①The protein expression level of SDF-1 in NRK-52E cells treated with TGF-?1 for 12 and 24 hours was higher than for 0 hour (P 0.05). This indicated the SDF-1 expression reached a flat stage, and 24 hour was the bets time to study the dose dependence. ②Both the mRNA and protein expression level analyses demonstrated that the expression of SDF-1 in NRK-52E cells treated with 2 ?g/L TGF-?1 for 24 hours was significantly higher than that in normal control group (P

10.Mechanism of Increased Myocardial Ischemic Vulnerability in Mice Type 2 Diabetes Mellitus Induced by Endoplasmic Reticulum Stress
Chinese Circulation Journal 2016;31(1):91-95
Objective: To study the relationship between endoplasmic reticulum stress (ERS) and adiponectin;to explore the role of ERS for increasing myocardial ischemic vulnerability in type 2 diabetes mellitus (DM) mice.
Methods: Type 2 DM model was established by high fat diet with streptozotocin (STZ) injection. A total of 35 C57BL/6J male type 2 DM mice were divided into 4 groups: ①Control group, n=5. ②Tauroursodeoxycholic acid (TUDCA) group,③Thapsigargin (TG) group and ④Normal saline group. The mice in Groups ②, ③, ④were fed by high fat and high glucose diet by injecting streptozotocin (STZ), in the last 3 weeks and respectively received intraperitoneal injections of TUDCA (250 mg/kg), thapsigargin (TG) (300μg/kg) and normal saline twice a day, n=10 in each group. Then myocardial infarction (MI) model was established in 5 mice from each group. 72 hours later, the MI ranges were measured, serum levels of adiponectin were detected, mRNA expressions of adiponectin and CHOP in myocardial tissue were examined.
Results: The MI range in TUDCA group (21.47 ± 2.85)%and in Normal saline group (39.92 ± 4.28)%were both lower than TG group (66.56 ± 8.15)%, both P<0.01. Before MI occurrence, serum levels of adiponectin in TUDCA group (79.25 ± 6.40) pg/ml and in Normal saline group (70.23 ± 4.15) pg/ml were both higher than TG group (62.64 ± 5.70) pg/ml, both P<0.01;serum levels of adiponectin in each group were higher than they were 72 h after MI. In each group, the mRNA expression and protein content of adiponectin in myocardial tissue were constant to serum adiponectin;while the mRNA expression and protein content of CHOP was opposite to serum adiponectin.
Conclusion: ESR could increase myocardial vulnerability in type 2 DM mice which might be related to down-regulating adiponectin expression.
