Chinese Journal of Pathophysiology 1989;0(06):-
Fever model was made by intravenously injected leucocytic pyrogen(LP,EP). Chai Ge Jie Ji Tang CGJJT fluid was perfused into rabbits stomach by mouth. 65 New Zealand white rabbits were divided into four groups: (1) control group; (2) LP group; (3) CGJJT fluid group; (4) LP+ CGJJT fluid group. Effects of CGJJT fluid on LP fever and cAMP concentration in cerebrospinal fluid (CSF)were observed. The results obtained from our experiments showed that: (1) The rectal temperature of normal rabbits markedly affected by CGJJT fluid. (2) Febrile response of LP was significantly inhibited by CGJJT fluid (P

3.Research progress on inflammatory immunity related signaling pathway for the pathogenesis of dry eye
International Eye Science 2016;16(6):1084-1088
?Dry eye ( DE) is a multifactorial disease of tear film and ocular surface. Inflammation in the ocular surface plays a main role in the pathogenesis of DE. Accordingly, inflammation and therapies that inhibit immune response may become topic for DE in recent years. Unfortunately, there are few studies about signaling pathway that has changed in ocular surface of DE. It is novel and there are few researches on how inflammation active signaling pathway and how it was regulated by signaling pathway on DE. This paper presents a review about inflammation active signaling pathway and its regulation on signaling pathway of DE.

Objective To study the effect of long-term fluoride excess on the activity of thyroid peroxidase (TPO) and the expression of TPO mRNA in rat thyroid,and explore the underlying mechanism.Methods Forty male SD rats were randomly divided into four groups based on their body mass(n =10 in each group):control group,low-fluoride group,moderate-fluoride group and high-fluoride group,and rats were fed on water containing 0.40(tap water),15.00,30.00 and 60.00 mg/L NaF,respectively,eating ordinary food formulated feed.All rats were sacrificed 180 days afterwards.Serum FT3 and FT4,TPO activity and mRNA expression level were determined by radio-immunoassay,modificd guaiacol method and semi-quantitative RT-PCR,respectively.Results Although serum FT3 levels in low-fluoride [(3.62 ± 0.47)pmol/L],moderate-fluoride [(3.57 ± 0.55)pmoi/L]and high-fluoride [(3.30 ± 0.68)pmol/L]treated groups were decreased compared with the control[(3.64 ± 0.45)pmol/L],the difference was not statistically significant (P > 0.05).Serum T4 levels of the high-fluoride group [(8.64 ± 1.72)pmol/L]were significantly lower compared with other groups[(13.08 ± 1.69),(12.68 ± 1.32),(12.05 ± 1.43)pmol/L,all P < 0.05].TPO activity in control,low-fluoride,moderate-fluoride and high-fluoride-treated groups[(1.572 ± 0.064),(1.414 ± 0.086),(1.322 ± 0.049),(0.960 ± 0.083)U/L]was decreased with the dose of fluoride increasing,the difference was statistically significant between any two groups(all P < 0.05).The TPO activity was negatively correlated with the dose of fluoride(r =-0.955,P < 0.05).With increased fluoride,the expression of TPO mRNA (0.936 ± 0.160,0.368 ± 0.095,0.115 ± 0.018,0.016 ± 0.008) decreased,the difference was statistically significant between any two groups (all P < 0.05).Conclusion Chronic fluoride excess inhibits the activity and the expression of TPO as well as thyroid hormone synthesis.

Objective To investigate the clinical significance of quantitation of TGF-?1 mRNA of peripheral blood mononuclear cell (PBMC) in type 2 diabetic patients at different stages of nephropathy (DN). Methods TGF-?1 mRNA transcription in PBMC was analyzed quantitatively by RT-PCR and dot blot in 93 cases of type 2 diabetic patients and 35 normal controls. Correlation of TGF-?1 mRNA in PBMC with 24 hours urinary albumin excretion rate (UAER) was also analysed. Results TGF-?1 mRNA level of PBMC in type 2 diabetic patients was significantly higher than that in normal controls (1.56?1.00 vs 1.03?0.25, P

ObjectiveTo observe the effect of long-term fluoride excess on rat thyroid morphology,thyroid peroxidase(TPO) activity and the expression of TPO protein,and to explore its possible mechanism of action.MethodsForty male SD rats were randomly divided into four groups by weight:control group,low-fluoride group,moderate-fluoride group and high-fluoride group(n =10),and they were fed with ordinary tap water containing fluorine 0.40,15.00,30.00,60.00 mg/L,respectively,and ate ordinary food prepared feed.After fed for 180 days,rats were anesthetized,and thyroid was taken.The morphology of thyroid was observed under light microscope.TPO activity was measured with improved guaiacol method.The expression of TPO protein was evaluated by Western blotting.ResultsThe thyroid histopathology results show:in control group,the thyroid follicular epithelial cells were columnar or cuboidal,with the follicular cavity filled with pink gum; in low-fluoride group,the thyroid follicular epithelial cell presented active hyperplasia; in moderate-fluoride group,the size of follicular increased,and follicular cavity was filled with dark,sticky colloid follicular; follicular increases,follicular cavity filled with dark,sticky colloid follicular; in high-fluoride group,the follicular epithelial cells showed apparent flat shape and excessive concentration of follicular colloid,a small amount of follicular lumen even showed the phenomenon of fusion,forming a giant follicular or cystic cavity.Among the four groups of control group,low-fluoride group,moderate-fluoride group and high-fluoride group,with increased fluoride,TPO activity [ ( 1.572 ± 0.046), ( 1.414 ± 0.086), (1.322 ± 0.049), (0.960 ± 0.083)U/L] decreased,and the differences were statistically significant between the two groups(all P < 0.05).With increased fluoride,the expression of TPO protein (0.335 ± 0.011,0.156 ± 0.027,0.084 ± 0.020,0.045 ± 0.002) decreased,and the differences were statistically significant between the two groups(all P < 0.05).Conclusioons Long-term intake of excessive fluoride can inhibit the thyroid TPO activity and the expressions of TPO as well as thyroid hormone synthesis,and leads to histological changes in rat thyroid.

Aldose reductase ( AR ) belonging to nicotinamide-adenine dinucleotide phosphate ( NADPH ) -dependent aldehyde-keto reductase superfamily, is the key rate-limiting enzyme in the polyol pathway which plays an important role in the body’s high-sugar metabolism. AR is widely present in the kidneys, blood vessels, lens, retina, heart, skeletal muscle and other tissues and organs, converts glucose to sorbitol which easy permeability of cell membranes, cause cell swelling, degeneration, necrosis, and have a close relationship with the development of chronic complications of diabetes mellitus. Diabetic retinopathy ( DR ) is a multifactorial disease, the exact cause is currently unknown, but polyol pathway has been demonstrated to play an important role in the pathogenesis of DR. Clinical risk factors such as blood sugar control, blood pressure and other treatments for DR only play a part effect of remission or invalid, if we can find out DR genes associated with the disease, this will contribute to a better understanding of the pathological mechanisms and contribute to the development of new treatments and drugs. The current research progress of AR, AR gene polymorphism, Aldose reductase inhibitors to DR was reviewed in this article.
