Hemolysins of Leptospira interragans have been shown to be the virulence factor in the pathogenesis of leptospirosis and 10 potential hemolysin genes were charecterized by genomic annotation of L.interrogans serovar.Lai strain 56601. In the present study, the LA0202 gene supposed to encode one of the new potential hemolysin was cloned and the protein encoded was purified. The purified protein was shown to have highly hemolytic activity as demonstrated on the sheep blood agar plate. It was also confirmed that the LA0202 protein-mediated hemolysis on sheep erythrocytes was osmotically protected by PEG6000. Meanwhile, this protein could induce pore formation on sheep erythrocytes and cause damages on the membrane of human L-02 liver cells. In addition, it could induce apoptosis of human L-02 liver cells after treatment of cells with this protein for 24 hours. It is evident that LA0202 protein acting as a pore-formong hemolysin can induce cytotoxic damage on mammalian cells.

Objective To investigate the clinical and laboratory profiles of a patient with pustular psoriasis-like skin lesion and cerebral palsy due to biotinidase deficiency. Methods A 5 year and 4 month-old boy with biotinidase deficiency was confirmed by urinary organic acid analysis with gas chromatography/mass spectrometry (GC/MS)and biotinidase activity assay of peripheral blood. His clinical features, laboratory findings, treatment and outcome were studied. Results The boy showed difficulty in taking food after birth, gradually eczema and pustules appeared at the age of 2 months, and generalized erythema and intractable pustular psoriasis-like lesion at the age of 8 months. His intellectual development was normal with retardation of locomotor system. He had muscular dystonia at the age of 6 months. Physical examination showed generalized pustular psoriasis-like lesion, generalized paralysis, hypertonic contracture of extremities, sparseness of scalp hair and severe malnutrition. Routine laboratory tests showed a mild anemia, metabolic acidosis and elevation of plasma creatine phosphokinase. Increased excretion of urinary lactate, pyruvate, 3-OH-propionate, propionylglycine, and 3-methylcrontonylglycine were observed. Biotinidase activity of his peripheral blood was below 0.1 pmol/min/3mm (normal 6.3-9.3 pmol/min/3mm). Biotin (10 mg/day) supplementation led to a dramatic recovery of the skin lesion. After the treatment of rehabilitation, his muscle power was also improved gradually. Conclusions Dermatological and neurological manifestations are the main features of biotinidase deficiency. Early diagnosis and biotin administration can greatly improve the clinical symptoms. Generalized pustular psoriasis-like lesion and cerebral palsy of this boy have improved after the supplementation of biotin, but he may be remained wheelchair-dependent because of delayed diagnosis.

Objective To study the expression level of thyroid insulin-like growth factor-Ⅰ (IGF-Ⅰ) in iodine deficiency and excess mice and the effect of thyroid gland IGF-Ⅰ in the thyroid morphological change. Methods Forty-eight Balb/c mice were chosen as studied objects,weighing about 16 g. They were divided into three groups: low iodine(LI,iodine content of 50 μg/kg in feed,drinking deironized water) group,normoi(NI,iodine content of 300 μg/kg in feed,drinking deironized water) group and high(HI,iodine content of 300 μg/kg in feed,iodoine of content 14 700 μg/kg in drinking) group,16 mice in each group. Mice were put to death after 12 weeks and taken out of their thyroid gland. The body weight,absolute and relative weights of thyroid gland were measured and the morphological change of thyroid gland were observed under microscope. The expression levels of thyroid gland IGF-Ⅰ mRNA and protein were detected by RT-PCR and immunohistochemistry,respectively. Results There were statistical significances between groups of thyroid absolute and relative weights(F = 315.881,405.921,all P < 0.01). LI group [(10.71±4.03) mg,(44.98±15.39)mg/100 g body weight]and HI group [(3.42±1.17)mg,(13.50± 3.89)mg/100 g body weight]had heavier thyroid absolute and relative weights than NI group[(2.11±0.53)mg,(8.35±1.98)mg/100 g body weight,all P < 0.01]. Under microscopy,the thyroid follicle capacity grew down and the follicle quantity grew up in LI group,the epithelium was stylolitic,the colloid diminished or absence in follicular cavity,while HI group presented colloid accumulation without follicular hyperplasia. The expression level of thyroid gland IGF-Ⅰ mRNA in LI group(1.03±0.32) was more than that in NI(0.65±0.19) and HI(0.59± 0.20) groups(F= 7.518,P< 0.01). In contrast to NI,there was no difference in the expression level of thyroid gland IGF-Ⅰ mRNA in HI group(P > 0.05). The brownish particles of LI group were more than NI and HI groups in the thyroid follicle epithelium by immunohistochemistry,while HI group was less than NI group. Conclusions The mice of iodine deficiency presented follicular hyperplasia goiter,the mice of iodine excess presented colloid accumulative goiter. The change of IGF-Ⅰ mRNA and protein expression may participate morphologleal change,indicating autocrine IGF-Ⅰ of thyroid gland may play an important role in regulating goiter formation.
