Objective To investigate the relationship of uteroglobin gene polymorphism to the sus-ceptibility to, clinical type and pathological type of Henoch-Schsnlein purpura (HSP) and Henoch-Schonlein purpura nephritis (HSPN). Methods Totally, 118 patients with clinically diagnosed HSP, including 80 cases of HSPN and 38 cases without renal involvement were recruited in this study together with 100 normal human healthy controls. Genomic DNA was isolated from peripheral blood leucocytes of all subjects. The uteroglobin G38A polymorphism was determined by PCR-restriction fragment length polymorphism (RFLP). Results The frequencies of genotypes 38GG, 38GA and 38AA in normal human controls did not differ from those in patients with HSP, patients with HSP but without nephritis, patients with HSPN, patients with HSP and joint involvement, patients with HSP and gastrointestinal involvement (all P > 0.05). Also, no sig-nificant difference was observed between patients with HSPN and patients with HSP but without nephritis (P > 0.05). Furthermore, the frequency of genotypes 38GG, 38GA and 38AA had no significant correlation to the clinical phenotype of HSP, the occurrence of gross hematuria and nephrotie syndrome or the degree of renal damage (all P > 0.05). A significant increase was observed in the frequency of genotype 38AA in patients with HSP with elevated serum IgE compared with those with normal serum lgE (58.82% vs 8.43%, χ2 = 21.946, P < 0.05, OR = 15.51, 95% CI range: 4.93% - 48.84%), whereas the frequency of genotype 38GG was significantly increased in patients with HSPN and hypertension than in those with HSPN but without hypertension (75.68% vs 18.60%, χ2 = 26.172, P < 0.05, OR = 13.61, 95% CI range: 5.01% -37.01%). Conclusions The uteroglobin G38A polymorphism seems unrelated to the susceptibility to and degree of renal damage in patients with HSP and HSPN. The genotype 38AA may be associated with elevated level of serum IgE In patients with HSP, while genotype 38GG is associated with a high incidence of hyper-tension in patients with HSPN.

A female patient with a dark red mass in the of preauricular area for over 3 months was hospitalized. Enhanced CT scan and ultrasonography showed that the mass had clear boundaries and was rich in blood supply. The patient was misdiagnosed as preauricular hemangioma, then the mass was removed as a benign tumor and found irrelevant to parot, SMA(+), Vim(+), S-100(+), indicating myoepithelial carcinoma. So a radical excision was performed to get negative incised margin. The patient didn't undergo postoperative chemotherapy but demonstrated no evidence of recurrence over a 12-month follow-up.

BACKGROUND:The glial scar is a major obstacle to the regeneration of the central nervous system, which plays a physical and chemical barrier role to central nervous system regeneration. How to effectively inhibit glial scar formation and promote axonal regeneration has great significance.
OBJECTIVE:To explore the effect of the immune response in the formation of the glial scar after spinal cord injury.
METHODS:A computer-based online search was performed in the PubMed database and the CNKI database for the articles on the mechanisms of spinal cord injury, immune cel s and spinal cord injury as wel as the glial scar formation after spinal cord injury from January 1990 to January 2013. The key words were “spinal cord injury, immunity, glia scar”in Chinese and English. The languages of the articles were limited in Chinese and English. Final y, 72 articles were included for the further analysis according the inclusion criteria.
RESULTS AND CONCLUSION: After spinal cord injury, the effect of autoimmune response in which stil been much debated. Studies showed that spinal cord injury can cause suppression of cel ular immunity and non-specific immune function, causing immune function decreasing. Monitoring immune indicators and improving immune function have great significance in promoting the ful rehabilitation of patients with spinal cord injury. Glial scar is the most important factor to prevent the repairing after spinal cord injury. Immune and inflammatory response is the main reason to secondary spinal cord injury. Degree of repair after spinal cord injury mainly depends on the protection of the residual neurons in order to keep them off secondary damage. However, autoimmune T cel s can protect the residual neurons, the specific effect of T lymphocytes in glial scar formation after spinal cord injury is stil unclear, and further exploration is needed.

Objective To explore the factors related to the delayed graft function (DGF). Methods Clinical data of 150 recipients were collected and performed by Cox proportional hazards regression analysis . In addition, the glutathione S-transferase (GST) gene polymorphism of 172 donors and 157 healthy persons was analyzed by multiple PCR and SSP-PCR. Results DGF was observed in 24 patients among 150 recipients. Pretranplantation dialysis mode, PR A levels and recipient gender were uncorrelated with the incidence of DGF(P>0. 05). Urinary volume of the second 24 hours after transplantation was an independent predictor of DGF(RR=1. 002, P = 0. 001). The frequency of donor's null GSTM1 in DGF group was significantly higher than that in non-DGF group(P<0. 05). Conclusions Urinary volume of the second 24 hours after transplantation could be a predictor for DGF. The null GSTM1 in donor might be one of the factors related to the EGF.
