Objective To investigate the relationship between polymorphism of arylamine N-acetyltransferase 2 (NAT2) and hair dye dermatitis in a Chinese population. Methods Polymorphism chain-restriction fragment length polymorphism (PCR-RFLP) was used and the wild-type allele (NAT2 * 4) and three mutant alleles (NAT2 * 5A, 6B and 7A) were determined in 60 patients with hair dye dermatitis and 73 age-matched control subjects in Tianjin region. Results In hair dye dermatitis cases, the frequency of NAT2 * 4, NAT2 * 5A, NAT2 * 6B, NAT2 * 7A was 52. 5 % , 5. 0 % ,26.7 % and 15. 8 %, respectively, and no statistically significant difference of the frequencies was found between the hair dye dermatitis patients and controls (P>0. 05). The frequency of rapid genotype, intermediate genotype and slow genotype was 26. 7 % , 51. 7 % and 21. 7 % in hair dye dermatitis cases, 30. 1 %, 50. 7 % and 19. 2 % in control subjects, respectively, and no statistically significant difference of the frequencies between the two groups (P>0. 05). Conclusions Our study suggests that there might be no relationship between polymorphism of NAT2 and genetic susceptibility to hair dye dermatitis in a Chinese population.

[Objective]To investigate the effect of Luteolin on mRNA expression ,protein expression and enzyme activity of 11β-Hydroxysteroid Dehydrogenase (11β-HSD) in rats.[Methods]Twenty-four rats were randomly divided into 4 groups and orally administrated with vehicle(1 % CMC-Na solution)or Luteolin(5,10 or 20 mg/kg daily)for 14 days. Gene expression of 11β-HSD I and 11β-HSD II in liver and kidney was determined with quantitative RT-PCR method. Protein expression was deter-mined with quantitative Western Blot method. The enzyme activity was expressed as the production rate of metabolites of prednisone and prednisolone.[Results]Luteolin significantly induced gene expression of 11β-HSD I and inhibited gene expression of 11β-HSD II in liver tissues ,significantly inhibited gene expression of 11β-HSD I and induced gene expression of 11β-HSD II in kid-ney tissues. Luteolin obviously up-regulated protein expression of 11β-HSD I and down-regulated protein expression of 11β-HSD II in liver tissues ,down-regulated protein expression of 11β-HSD I and up-regulated protein expression of 11β-HSD II in kidney tissues. Luteolin significantly induced activity of 11β-HSD I in liver and11β-HSD II in kidney.[Conclusions]Luteolin could change the activity of corresponding enzyme through affecting gene expression ,protein expression and enzyme activity of 11β-HSD I and 11β-HSD II in liver and kidney tissues in rat ,and affect in vivo activation of glucocorticoids and hormone level in liver and kidney.

OBJECTIVE:To investigate the relationship between Tacrolimus blood concentration and effectiveness after renal transplantation and to find factors affecting Tacrolimus blood concentration METHODS:Steady-state trough concentrations of Tacrolimus were collected from 80 renal transplantation patients RESULTS:The effective blood concentration of Tacrolimus was associated with course of treatment CONCLUSIONS:The therapeutic concentration of Tacrolimus was between 12ng/ml and 15ng/ml during the first 2 weeks after renal transplantation,then should be 8ng/ml～15ng/ml

OBJECTIVE To find the infla mmation bio markers induced by coke oven e missions (COE),we investigated the changes of T helper 17 (Th17 )cytokines in hu man bronchial epithelial (16HBE)cells.METHODS 16HBE cells were exposed to organic extracts of COE collected fro m co-king plant at the concentrations of 5,10 and 20 mg·L -1 for 24 h or 5 d to establish short-term and long-term cell models,respectively.Cell viability was measured by MTT assay and infla mmatory da mage was assessed by lactate dehydrogenase assay (LDH).The cytokines in culture supernatant sa mples was detected by co mmercial hu man Th17 cytokine panel kit.RESULTS COE Can induce infla mmation in COE 20 mg·L -1 group and no expression on IL-17 F and IL-1 β.The concentration of IL-10 was 1 .25 ± 0.54,1 .39 ±0.13 and (1 .90 ±0.73)pg·mL -1 in COE 5,10 and 20 mg·L -1 group showing good con-centration-effect relationship (r=0.98,P <0.05 ).IL-23 expression was found only higher at 10 and 20 mg·L -1 and the concentrations were 3.38 ±3.90 and (1 .74 ±2.00 )pg·mL -1 ,respectively.In 16HBE cells treated by COE for 5 d,elevated expression of IL-17A was found in COE 5 and 10 mg·L -1 group,and there was statistically sigificant difference between COE 10 mg·L -1 and DMSO group (P<0.05).Elevated concentration of IL-17F of 10.2 ±1 1 .78 and (6.79 ±7.84)pg·mL -1 was found in COE 5 and 10 mg·L -1 group.The concentration of IL-10 was 1 .71 ±0.02,1 .49 ±0.25 and (2.82 ± 0.33)pg·mL -1 in COE 5,10 and 20 mg·L -1 group,respectively.We found increased IL-1 βexpression with concentration of 2.72 ±0.62,2.25 ±0.33 and (0.93 ±0.21 )pg·mL -1 in COE 5,10 and 20 mg·L -1 group with negative dose-response relationship.We also found more elevated TNF-αlevels in the 5 d than in the 24 h model with no COE specific relationship.CONCLUSION COE induces expression changes of Th17 cytokines profile in 16HBE cells,including IL-23 and IL-1 βfor early and long-term infla mmation,respectively.IL-10 may be a candidate marker for population study on COE induced infla mmatory injury.

Objective To observe the effect of Motomed Gracile on spastic cerebral palsy. Methods 48 cerebral palsy children were divided into two groups: intervention group (n=24) and control group (n=24). The children in the control group accepted comprehensive rehabilitation, while the children in the intervention group were trained with Motomed Gracile in addition. They were evaluated with Ashworth Assessment and manual muscle testing (MMT) 6 months after treatment. Results The scores of intervention group improved more significantly than those in control group （P<0.05）. Conclusion Motomed Gracile can facilitate the recovery of children with spastic cerebral palsy.

A 53-year-old man was admitted to the hospital for verrucous hyperplasia on the circular sulcus for 2 years as well as erythematous painful swelling, ulcer and rupture of inguinal lymph nodes for more than 2 months. Physical examination revealed erythematous, indurated and painful swelling of bilateral inguinal lymph nodes. Fluctuation could be felt at the centre of the right swollen inguinal lymph nodes, where several pores were seen with yellowish-white purulent fluid flowing out, giving the appearance of a watering can. Multiple swollen or ulcerative lymph nodes were separated by the inguinal ligament forming the groove sign.There were irregular, indurated, verrucous, proliferative and keratinized lesions sized 1 cm × 2 cm on both sides of the circular sulcus. The right scrotum was obviously swelling. Erythematous, fluctuating swelling, ulcer and rupture of the glans fraenum were also observed with yellowish-white purulent exudates. Neither the secretion from the skin lesions on the surface of bilateral inguinal lymph nodes nor the puncture sample from the right groin was positive for multiple fungal or bacterial culture, acid-fast stain or first culture of C. trachomatis.However, the endogenous plasmid of Chlamydia was successfully amplified by PCR from these samples, and restriction fragment length polymorphism (RFLP) analysis of the major outer membrane protein (MOMP) suggested that the genotype of the Chlamydia strain was L3. Western blot revealed the presence of anti-MOMP antibodies and anti-Pmp H antibodies (titer: ＞ 1: 800) in serum. Culture of C. trachomatis also gave positive results after multiple passage. Biopsy of the verrucous hyperplasia on the right groin is consistent with well-differentiated squamous cell carcinoma of the skin. A diagnosis of lymphogranuloma venereum complicated by cutaneous squamous cell carcinoma was made.
