Objective To review the clinical and histopathological features,management and outcomes in 67 patients with seba- ceous carcinoma of the eyelid.Design Retrospective case series.Participants Sixty-seven cases of the sebaceous gland carcinoma were retrieved from the ophthalmology archives of Tongren Hospital between 1996 and 2005.Methods Clinical data of all patients were re- viewed from the charts.Pathology specimens were reviewed in all cases.Main Outcome Measure Presenting features,sites of origin, location,differentiation,management,histopathologic findings,and incidence of recurrence in 67 patients.Results A total of 36 female and 31 male patients were identified.The mean age at diagnosis was 59 years (range from 35 to 84).Initial clinical diagnoses elsewhere were sebaceous carcinoma (43.28%),chalazion (25.37%),basal cell carcinoma(7.46%).Initial histopathologic diagnoses were sebaceous carcinoma(79.10%),basal cell carcinoma(5.97%),squamous cell carcinoma(1.49%) and other or not available(4.48%).The initial treat- ment involved excisional techniques with reconstruction in 42 cases,anti-inflammatory in 12 cases,without any treatment in 10 cases. 61.19% cases presented the pagetoid invasion.Local recurrence developed in 58.21% and two died from metastatic sebaceous carcino- ma (8.70%).Regional lymph node excision was performed in 13.04% because of local metastases.Five year survival rate was 94.87%. Conclusions About 1/3 cases had not receive the right treatment at initial diagnosis eyelid.The recurrence rate of patients was still high.

Expression of prepro-orexin gene in the hypothalamus was decreased in rats with dietary obesity,and has no correlation with serum corticosterone concentration.Expression of orexin receptor-2 in adrenal was increased in obese rats,and was positively correlated to expression of CRH mRNA and inversely correlated to serum corticosterene concentration.

OBJECTIVETo evaluate the effect of astragalus (As) on cytokines in patients undergoing heart valve replacement (HVR).

METHODSThirty patients undergoing HVR were randomized into the As group and the control group. Cardiopulmonary bypass (CPB) was set up routinely and to the As group, As injection (40 mL, 10 mL containing 2 g of crude drug) was added into the prime solution just before CPB. Blood samples were collected at different time points during and after CPB for cytokines determination, including tumor necrosis factor alpha (TNF-alpha), interleukin-6 (IL-6), IL-8 and IL-10 by ELISA.

RESULTSAll the indexes measured were insignificantly different between groups before skin incision, they began to increase by the end of CPB (P < 0.05), reached the peak 3 h after CPB and then decreased gradually, TNF-alpha returned to the baseline level 24 h after operation. Meanwhile, levels of IL-6, IL-8 and IL-10 decreased obviously but still above the baseline. Comparisons between groups at different time points showed that levels of IL-6 were not different significantly (P > 0.05), those of IL-10 were higher at all time points, and TNF-alpha and IL-8 at 3 h, 6 h and 12 h after CPB were significantly lower in the As group (all P < 0.05).

CONCLUSIONAstragalus may decrease the inflammation cytokine promoting factors, and increase the level of anti-inflammatory cytokine (IL-10), so it could attenuate the inflammation reaction in patients after HVR.

OBJECTIVE: To explore the correlation between microvascular density (MVD) and dynamic contrast-enhanced MRI in the glioma. METHODS: We examined 35 patients with histologically verified glioma. Gadolinium-enhanced dynamic TurboFLASH imaging was performed preoperatively in all patients followed by conventional MRI. The steepest slope (SSmax) of curve and corresponding Tm1 in "first-pass" phase were obtained by analyzing time-signal curve. All specimens were immunostained with anti-human Factor VIII relative antigen monoclonal antibody postoperatively by streptavidin-peroxidase method to obtain the MVD. The correlation between SSmax, Tm1, and MVD was analyzed. RESULTS: SSmax was positively correlated with MVD (r = 0.640, P < 0.01). Tml was negatively correlated with MVD (r = -0.671, P < 0.01). CONCLUSION The MVD correlates obviously with SSmax and Tml in the glioma. Analyzing the time-signal curve of dynamic contrast-enhanced MRI is helpful to predict the angiogenesis in the glioma.

Objective The aims of this study were to determine the expression of CXCR family proteins in various subtypes and adjacent tissues of breast cancer and its relationship with prognosis,and to provide a reference for clinical diagnosis,treatment and prognosis of breast cancer. Methods The mRNA expressive profiles of CXCR family proteins in paracancerous tissues and different subtypes of breast cancer tissues were obtained from the TCGA(The Cancer Genome Atlas)database. The prognostic survival analysis of each differentially expressed protein was obtained using the PRECOG website. Results Except for CXCR1,the expression of CX-CR family proteins in breast cancer tissues and adjacent tissues was statistically different( P<0. 05). CXCR2P1,CXCR3,CXCR4, CXCR5 and CXCR6 were highly expressed in breast cancer tissues,CXCR2 and CXCR7 were lowly expressed in breast cancer tis-sues. The expressive levels of CXCR3,CXCR4 and CXCR7 were associated with the prognosis of patients. Conclusion The expres-sions of CXCR3,CXCR4 and CXCR7 in breast cancer tissues and adjacent tissues is significantly different,and its expression is related to the prognosis of breast cancer patients,which may be a potential target for molecular diagnosis or targeted therapy of breast cancer.

Objective To express and purify GRIK3 intracellular region protein in prokaryotic cell system. Methods The histamine(His)tagged GRIK3 intracellular region recombinant plasmid pCzn1-GRIK3-in-tra was constructed and transformed into Escherichia coli(E.coli). The His-GRIK3-intra recombinant protein was expressed after the induction with IPTG. The target protein was purified by Ni-NTA affinity chromatography column. Results The prokaryotic expression plasmid pCzn1-GRIK3- intra was successfully constructed and the GRIK3 intracellular region protein in E.coli were efficiently expressed after the induction with IPTG. The purified target pro-tein was successfully obtained by Ni-NTA affinity chromatography column. Conclusion The successful construc-tion of prokaryotic expression plasmid expressing GRIK3 intracellular region gene and preparation of high purity GRIK3 intracellular region protein have paved the way for further exploration of the intracellular signal transduction mechanism of membrane protein GRIK3.

OBJECTIVETo assess the feasibility of usage of microbubbles conjugated with RGD peptides and contrast enhanced ultrasound (CEU) in detection of tumor angiogenesis.

METHODSLipid microbubbles (MB) were prepared, and the RGD peptides were covalently conjugated to the lipid shell of MB (MB(RGD)). Six nude mice with tumor created by dorsal inoculation of HepG2 tumor cells were used as the test group. Six nude mice without tumor were served as the control group. 10 minutes after bolus injection of MB and MB(RGD) randomly (30 min interval) via a tail vein catheter, CEU was performed on the tumors of the test group and the thigh skeletal muscles of control group. The video intensity (VI) of tumors and the skeletal muscles were measured. The tumors and the skeletal muscles were harvested for immunohistochemical examination.

RESULTSOnly a slight contrast enhancement of the tumor was seen with MB, and the VI was 5.33 ± 1.71. While a remarkable enhancement of the tumor was observed after injection of MB(RGD). The VI was up to 17.03 ± 3.58, 3.18 folds higher as compared with that obtained by injection of MB (P < 0.05). As expected, there were no obvious contrast enhancement of the skeletal muscles with both MB(RGD) and MB. There was a high expression of αvβ3-integrin in tumor neovascular endothelium, however, no apparent expression of αvβ3-integrin was observed in the skeletal muscle vascular endothelium.

CONCLUSIONCEU with MB(RGD) can be used to effectively evaluate the angiogenesis of tumors, and it may greatly contribute to the early judgement of the nature of tumor.
