Objective To measure the fluorescence spectral information of UVRF in the facial skin of patients with acne vulgaris and seborrheic dermatitis and to comprehend the optical properties of UVRF.Methods The lesions were squeezed to extract the sebaceous secretions containing UVRF in the facial skin.Ocean Optics USB2000 +F02243 Spectrometer and the 308nm excimer laser were used as an excitation light source to measure the signal of the LIF spectrum of UVRF in 6 acne vulgaris and 4 seborrheic dermatitis patients' facial part,compared with protoporphyrin Ⅸ.Results 1-4 peaks were detected in 10 patients' UVRF specimen respectively.The fluorescence spectra's characteristic peak of UVRF in 10 patients was at 680 nm.Protoporphyrin Ⅸ was at 688 nm and more gentle and generous than UVRF's characteristic peak.Conclusions LIF system can be used to detect the fluorescence spectroscopy of UVRF.UVRF has similar spectral characteristics to protoporphyrin Ⅸ,but it is not the same species.

Objective To evaluate the effect of an equivalent uiform dose optimization (EUD) based optimization algorithm in sparing the organ at risk (OAR) of tumor treated with intensity-modulated radiation therapy (IMRT).Methods 10 patients of nasopharyngeal carcinoma (NPC),10 patients of esophagus cancer,6 patients of rectum cancer were randomly selected from all patients received IMRT treatment.Then physical optimization constraints (dose/dose-volume constraints) were designed as EUD optimization,while the physical objectives for targets and other OAR were unchanged.Results There was statistically significant difference in protecting OAR in 8 NPC patients of PLANED group compared with those of PLANNO_EuD group (t values were 2.590,2.352,3.656,2.148,2.283,3.683,2.192,2.353,2.146,2.276,2.126,P ＜ 0.05).There was no statistically significant difference in protecting OAR in 10 cases of esophageal cancer between PLANEUD group and PLANNO_EUD group (t value were 0.408,0.427,0.920,P ＞ 0.05).There was statistically significant difference in protecting OAR in 6 cases of rectum cancer of PLANED group compared with those of PLANNO_EUD group (t values were 2.332,2.693,2.279,2.244,P ＜ 0.05).Conclusion EUD optimization can reduce the doses to OAR which may be quite helpful to reduce the occurrence rate of OAR complications.

Objective To investigate the relationship between the expression of T lymphoma invasion and (metastasis) inducing factor 1 (Tiam1), ras-related C3 botulinum toxin substrate 1 (Rac1) with the invasion and metastasis of gastric cancer. Methods The expressions of Tiam1 and Rac1 proteins in 60 cases of (gastric) cancer and paracarcioma gastric mucosa tissues were detected using Strept Avidin-Biotin Complex(SABC) immunohistochemical method,and the correlation between the expression of Tiam1, Rac1 and (clinicopathological) parameters of gastric cancer were analysed. Results (1)There was negative staining of Tiam1 protein in paracarcioma gastric mucosa tissues, while positive staining was detected in gastric cancer (tissues)(78.33%)(P 0.05). (4) The expression of Rac1 in patients with positive staining of Tiam1 was significantlyhigher than that in patients with negative staining(P

In recent years, the medical graduates who take part in postgraduate examination have been increasing each year. The preparation for postgraduate examination affects the clinical practice, but not yet has a quantitative report. This article studied the students in general surgery, which were divided into postgraduate examination group and clinical practice group. By comparing the theoretical knowledge results and the clinical practice skills between the two groups we found that there was no difference between the two groups in the theoretical and operating skill when they were just in the department, and the operating results in the clinical practice group were better than the postgraduate examination group when they were out of the department.

BACKGROUND: Existing research shows that in situ regeneration of skin deep within the second degree bum wound and donor site wound healed without physical scarring, can promote three-degree burn wounds liquefied necrotic tissue removement, the growth of transplanted skin, reduce scar; scar-shift using the in situ regeneration is expected to reach significantly reduce scar symptoms, and to reduce the effect of scar, which have not be reported.OBJECTIVE: To observe effects of skin regeneration in situ method to remove scar in the treatment of hypertrophic scar. METHODS: A total of 32 patients with many hyperplastic scars, including 25 males and 7 females, aged 16-52 years, disease course of 1-11 years. Two similar scar regions were selected from each patient for self control. In the experimental group, scar removal, scar skin replantation after the application of in situ regeneration of the skin treatment using burn cream coated yarn. In the control group, scar removal, scar skin replantation after the application of traditional Vaseline covered by treatment. Curative effects were observed and compared. Scar hyperplasia was assessed using Vancouver Scar Assessment Scale assessment. RESULTS AND CONCLUSION: Replanted scar skin explants were survived in both groups. In the experimental group, healing speed and quality of wound surface were better than the control group (P< 0.05). After 6 months, the Vancouver Scar Assessment Scale assessment in the experimental group was better than control group (P < 0.05, P < 0.01). Scar caused by pain, itching and other symptoms disappeared, skin formation and color back to pre-implantation were significantly improved compared with the surrounding skin almost. Results indicated that with regarding to the lack of autologous skin source, large area of scar in patients with hypertrophic scars or unwilling to add a new donor site wounds in patients, in situ replantation method is an ideal approach.
