Objective To explore the effect of cosmetics on patients who have facial telangiectasis. Methods We treated 252 cases of facial and nasal telangiectasis with Vbeam laser machine made in USA. The wavelength is 595 nm. We chose proper pulse width and energy output according to the vascular diameter. The handle shaft should focus on the treatment locations when we treated the patients. The skin eruption turned grey and the telangiectasis disappeared after laser irradiation. The stellate telangiectasis and nasal telangiectasis could be cured after 1~7 times of laser irradiation. The puactate or filamentous telangiectasis and erythema, heliotrope patchy telangiecatasis could be cured after 1~3 times. The treatment interval was 1~2 months. Results All of the 252 cases of facial telangiectasis were cured. The cure rate was 100 %. The skin reaction to the laser irradiation was slight. 30 % of the patients showed hyperpigmentation, which could disappear spontaneously after 1~6 months. In addition, we found patients' faces become more smooth and less wrinkles. Conclusion Satisfied effects are archieved in facial telangiectasis with Vbeam laser machine. This treatment has no scar and no recurrence with only slight skin reaction. And the skin becomes smooth and less wrinkles. Therefore, it is a good choice to treat facial telangiectasis with Vbeam laser irradiation.

ObjectiveTo investigate the role of T-type calcium channel in the spinal neurotoxicity of intrathecal (IT) lidocaine in rats.MethodsForty-eight adult male SD rats in which IT catheter was successfully implanted,weighing 230-270 g,were randomly divided into 4 groups ( n =12 each):dimethyl sulfoxide (DMSO)group (group D),lidocaine group (group L),mibefradil + lidocaine group (group M),normal saline + lidocaine group (group N).Another 12 rats served as control group (group C).DMSO and 10% lidocaine 20μl were injected intrathecally in groups D and L respectively.After mibefradil 200 μg/10μl and normal saline 10 μl were injected intrathecally in groups M and N respectively,10% lidocaine 20 μl was injected intrathecally in the two groups.The mechanical withdrawal threshold (MWT) and thermal withdrawal latency (TWL) were measured before IT injection and at 2,4,8 and 12 h and 1,2,3,4 and 5 d after IT injection (T0-9).Four rats were sacrificed at T6 in each group and their lumbar enlargements were removed for microscopic examination.ResultsCompared with group C,no significant change in MWT and TWL was found at each time point in group D,MWT was significantly increased at T1-8 and TWL was significantly prolonged at T1-7 in groups L and N,and MWT was significantly increased at T1-6 and TWL was significantly prolonged at T1-6 in group M ( P < 0.05 ).Compared with groups L and N,MWT was significantly decreased at T1-4 and TWL was significantly shortened at T1-4 in group M ( P < 0.05).Pathological injury was significantly reduced in group M as compared with groups L and N.ConclusionT-type calcium channel is involved in the spinal neurotoxicity of IT lidocaine in rats.

Objective To evaluated the role of wt-P53 protein in telomerase regulation in keloid fibroblasts(KFBs). Methods The fibroblasts were derived from human keloid tissue which was proved by pathological diagnosis. KFBs were divided into 2 groups, the transfection group and the untransfection group. wt-p53 gene was transfected into the fibroblasts by adenovirus vectors in the transfection group. The KFBs untransfected with wt-p53 gene served as control (untransfection group). After 48 hours of transfection, the expression of wt-P53 protein was analyzed by both Western blotting and immunofluorescence method, respectively. The telomerase activity was evaluated by TRAP-ELISA after 1-7 days of transfection.Results All the KFBs from 2 groups expressed wt-P53 protein. But the expression level of wt-P53 protein in the transfection group was significantly higher than that in the untransfection group. At the same time of high expression of wt-P53 protein, the telomerase activity of KFBs in transfection group was significantly lower than that in the untransfection group( P<0.05). Conclusion High level expression of wt-P53 protein can transiently inhibit the telomerase activity of KFBs.

Lactic acid production of twelve strains of LAB isolated from broiler intestine and tolerance property of three strains were investigated. The results of lactic acid production showed that among all strains K6 exhibited the most rapid production during the first twelve hours, the seconds were K9 and C1; D17 exhibited the highest production of lactic acid by twenty-four hours, C1 exhibited the highest production of lactic acid by forty-eight hours. The pH values in three strains of K9、D17 and C1 culture showed the fast decline during the first twelve hours, with the final values significantly lower than those of other strains cultures. The results of tolerance property showed that the survival counts of C1could be detected when pH value was at 2 after three hours, but the survival counts of D17 and K9 could not be detected after one hour. When pH value was at 2.5 after three hours ,the survival counts of C1 declined from 10~ 8.2 /mL to 10~ 4.8 /mL, K9 from 10~ 8.2 /mL to 10~ 4.6 /mL, the survival counts of D17 could not be detected. 0.08% bile had few effects on the survival counts of three strains; when incubated in the medium with 0.40% bile, the survival counts of C1 declined from 10~ 8.4 /mL to 10~ 6.5 /mL,D17 from 10~ 10.3 /mL to 10~ 7.5 /mL, and K9 from 10~ 9.8 /mL to 10~ 7.7 /mL. When the group treated with 37℃ for 20 minutes was served as the control, the survival counts of C1 and K9 was not detected when treated with 80℃, but the survival counts of D17 were 10~ 4.9 /mL, when treatment with 65℃ the survival counts of C1 and K9 decreased significantly .

Objective To investigate the clinical significance of serum procalcitonin (PCT),C reactive pro-tein(CRP),and lymphocyte subsets CD +19 CD +23 in children with Kawasaki disease (KD).Methods From August 2013 to July 2015 in hospital,30 cases of acute phase KD were selected.According to cardiac color Doppler ultra-sound results,30 patients were divided into coronary artery disease (CAL)group and non coronary artery disease (NCAL)group.The intravenous immunoglobulin (IVIG)before and after treatment,serum PCT,CRP,CD +19 CD +23 were detected.And 30 healthy children were selected as normal control group.Serum PCT was detected by chemilumines-cence immunoassay,CRP was determined by immune latex ratio method,CD +19 CD +23 was measured by flow cytometry. Results The levels of PCT,CRP and CD +19 CD +23 were (1.37 ±0.39)μg/L,(52.24 ±12.99)mg/L,(25.45 ± 11.06)% respectively in KD before IVIG treatment,which were significantly higher than those of KD after treatment [(0.49 ±0.24)μg/L,(37.48 ±6.27)mg/L,(17.23 ±1.97)%]and the control group[(0.05 ±0.00)μg/L, (16.08 ±5.21)mg/L,(15.76 ±2.39)%],the differences were statistically significant (t =6.108,5.983,8.172, all P <0.01).In CAL group,PCT[(1.75 ±0.53)μg/L,(65.95 ±14.55)mg/L]and CRP[(0.93 ±0.42)μg/L, (26.18 ±6.71)mg/L]were higher than NCAL group,the differences were statistically significant (t =5.504,5.621, all P <0.05).While CAL group CD +19 CD +23 [(24.70 ±11.86)%]and NCAL group[(25.79 ±10.59)%]had no statistically significant difference (t =0.559,P >0.05 ).Conclusion PCT,CRP and CD +19 CD +23 can be used as important index for early diagnosis and prediction of KD,the levels of CRP and PCT have clinical significance in the assessment of coronary artery lesions.

Objective To investigate the relationship between the initial change of Tg and clinical outcome in DTC patients with pulmonary metastases after 131I treatment.Methods A total of 47 DTC patients (13 males,34 females;average age (41.6±16.3) years) with pulmonary metastases from January 2008 to June 2014 were retrospectively analyzed.Patients were divided into 3 groups according to the variation of Tg: G1 with a declined (more than 50%) Tg;G2 with a declined (less than 50%) Tg or an increased (less than 10%) Tg;G3 with an increased (more than 10%) Tg.The median follow-up time was 1 501 d.Clinical outcomes were divided into remission,stable disease and progressive disease according to the serum test and imaging results.Data analysis was performed by χ2 test and Fisher exact test.Results The percentage of G1,G2,G3 patients was 44.7%(21/47),40.4%(19/47),and 14.9%(7/47) respectively.Results of follow-up showed 19.0%(4/21) patients achieved remission and 81.0%(17/21) with stable disease in G1.There were 2/19 with remission,12/19 with stable disease and 5/19 with progression disease in G2.All patients (7/7) had progressive disease in G3.The clinical outcome was related to the variation of Tg after 131I treatment (Fisher exact test,P<0.01).Conclusions Initial Tg after 131I treatment could be a predictor to the outcome of patients.The increased Tg level indicates a high possibility of 131I refractory disease.
