Tyrosinemia type Ⅰ is an autosomal recessive disease characterized by severe liver and kidney damage.Patients with this disease may develop acute liver failure and have a high risk of hepatocellular carcinoma.The diagnosis is confirmed by elevated tyrosine serum levels and large amounts of succinylacetone in blood and urine.Nitisinone has been significantly effective in treatment of the disease,while dietary therapy with restriction of phenylalanine and tyrosine is necessary at the same time.Liver transplantation has been performed in a few patients and has a positive effect.Experimental work in model mice has provided some promise for gene therapy to this disorder.

BACKGROUND:The repair of temporomandibular joint disc is stil a great clinical chal enge. Pluripotent adipose-derived mesenchymal stem cells bring a hope for fibrocartilage tissue repair. Up to now, there are few studies concerning transforming growth factor-β3 to induce differentiation of adipose-derived mesenchymal stem cells into fibrochondrocytes.
OBJECTIVE:To observe the growth and morphology of adipose-derived mesenchymal stem cells under the induction of transforming growth factor-β3.
METHODS:We observed the morphology of fibrochondrocytes differentiated from adipose-derived mesenchymal stem cells under the induction of transforming growth factor-β3. Histological and immunofluorescence staining were employed to detect the expression of extracellular matrix Ⅰ, Ⅱ col agens and proteoglycansthe produced by adipose-derived mesenchymal stem cells. We also evaluated the feasibility of adipose-derived mesenchymal stem cells as seed cells for fibrocartilage tissue engineering.
RESULTS AND CONCLUSION:Under the inverted fluorescence microscope, induced cells showed obvious aggregation growth, polygonal shape, and increased secretion of extracellular matrix. Alcian blue staining results showed that under the induction of transforming growth factor-β3, adipose-derived mesenchymal stem cells exhibited the distinctly deep blue, indicating a large number of glycosaminoglycan was synthesized. Immunostaining results showed that under the induction of transforming growth factorβ3, adipose-derived mesenchymal stem cells synthesized extracellular matrix Ⅰ, Ⅱ col agen. These findings suggest that transforming growth factorβ3 can induce adipose-derived mesenchymal stem cells to differentiate into fibrouscartilage-like cells, and that adipose-derived mesenchymal stem cells can serve as seed cells for fibrocartilage tissue engineering.

Methods Totally 120 patients with subclinical hypothyroidism and 50 cases of normal healthy subjects were selected. TCM constitutional types of two groups were distinguished by KY3H TCM physique recognition software. CIMT was determined, and the correlation between the distribution of TCM constitutional types and CIMT in patients with subclinical hypothyroidism was analyzed. Results In 120 cases of subclinical hypothyroidism, there were 3 cases of gentleness type (2.50%), 30 cases of qi-depression type (25.00%), 28 cases of qi-deficiency type (23.33%), 25 cases of yang-deficiency type (20.83%), 13 cases of phlegm-damp type (10.84%), 9 cases of yin-deficiency type (7.50%), 6 cases of blood stasis type (5.00%), 5 cases of dampness heat type (4.17%), 1 case of particular type (0.83%). The main TCM constitutional types of subclinical hypothyroidism were qi-depression type, qi-deficiency type, yang-deficiency type and phlegm-damp type. The morbidity of atherosclerosis in patients with qi-depression type and qi-deficiency type were higher than other constitutional types. Conclusion The main TCM constitutional types of subclinical hypothyroidism were qi-depression type, qi-deficiency type, yang-deficiency type and phlegm-damp type.
