BACKGROUND: The soft tissues would shrink with nasal framework collapse following surgical trauma, which cause aseptic inflammation, lead to parts of cartilage resorption. Accordingly, long-term saddle nose deformity usually accompanied by short nasal columella. Complications such as skin perforation or ulceration would appear if corrected the deformity using medical silicone rubber with large tension.OBJECTIVE: To explore the effectiveness of repairing post-traumatic saddle nose deformity with autologous costal cartilage transplantation.METHODS: A total of 21 cases with post-traumatic saddle nose deformity accompanied by short nasal columella were selected, including 6 males and 15 females, aged 16 45 years. All of the cases had trauma history and agreed with the treatment. The costal cartilage was obtained from the seventh rib and formed to babylon weeping willow leaf shape and columella nasi stent to repair post-traumatic saddle nose deformity. The "V-Y" progradation suture was used in the philtrum introcession and the botton of nasal columella to extend the nasal columella. The recovery of saddle nose deformity after transplantation, discharge of transplanted cartilage, as well as the incision scar status was observed.RESULTS AND CONCLUSION: The results were satisfactory and there were no complications after transplantation. All the cases were followed up from 6 months to 2 years. No case suffered costal cartilage grafts discharge or chondral deformation. The scar was little at the bottom of nasal columella. It is an ideal method for repairing post-traumatic saddle nose deformity using transplantation of autologous costal cartilage with "V-Y" progradation suture.

Objective To explore the influencing factors of ALT abnormality among workers from food industry and related people from public places in Shenzhen and influencing factors.Methods 2,411 workers from food industry and people from public places who had physical examinations in our department from May to October in 2013 were involved in the investigation.ALT abnormality rate and the influencing factors were analyzed.Results The incidence of ALT abnormalities among workers from food industry and related people from public places in Shenzhen was 9.37%.The ALT abnormalities were correlated with censue register,gender,age,marital status,work duration in Shenzhen,education level and monthly income respectively(all P<0.05). Conclusion The ALT abnormality has a higher rate among people from cities,of male gender and old age,with longer work duration in Shenzhen and relatively high level of education and higher monthly income.Therefore,for the population,the health education should be strengthened and the healthy lifestyles should be advocated to effectively reduce the ALT abnormality rate.

Objective To investigate the effects of exogenous transforming growth factor-β3 (TGF-β3) on the expression of endogenous TGF-β3 and proliferation of rat hepatic stellate cells (HSC).MethodsRat HSC cells were seeded in 24-well plates and were divided into 2 groups.One group of cells were exposed to TGF-β3 of different concentrations (0.08,0.4,2,10 and 50 ng/ml) for 2 hours and then the cell culture supernatant was collected; the other group of cells were exposed to 10 ng/ml TGF-β3 and the cell culture supernatant was collected at different time point (0.25,0.5,1,2,4,8 and 13 h).The content TGF-β3 was determined by ELISA method.Some other HSC cells were seeded in 96-well plates and divided into 2 groups.One group of cells were cultured in the presence of exogenous TGF-β3 of different concentrations (0.001,0.005,0.02,0.08,0.32,1.25,5,20,100,500 ng/ml) for 24 hours and then the cell proliferation was detected; the other group of cells were treated with 5 ng/ml TGF-β3 for 24 and 48 hours.The cell proliferation was measured by MTT method.The HSC cell morphology of control group and TGF-β3 treated group was observed under inverted microscope. Results The endogenous TGF-β3 expression of HSC cells obviously increased after exogenous TGF β3 treated at 2 ng/ml and reached the peak at 3 hour [(0.845±0.028) ng/ml vs (0.026±0.021) ng/ml,F=210.168,P=0.00].Low concentrations of exogenous TGF-β3 did not affect the proliferation of HSC cells.Above 0.32 ng/ml,exogenous TGF-β3 could promote HSC proliferation.There was no dose-dependent relationship between HSC cell proliferation and the concentration of exogenous TGF-β3 (F=0.68,P=0.57).Under microscope,lhere was no significant difference in HSC cell morphology between control group and TGF-β3 treated group.Conclusions Exogenous TGF-β3 can promote the expression of endogenous TGF-β3 in HSC cells,and can promote HSC cell proliferation.There is no obvious effect of exogenous TGF-β3 on HSC morphology.

Objective To observe the effects of one kind of angiotensin converting enzyme inhibitor (ACE1) drugs fosinopril (FOS) on transforming growth factor β1 (TGF-β1)and β1- integrin( Itg-31 ) expression in rat glomerular mesangial cells (GMC)induced by lipopolysacchatide (LPS).Methods We established the cultured glomerular mesangial cells of rat in vitro and passages 3 ～ 10 of cells were used in the experiment after identification.The experiment included the following groups:Control group,LPS induced group (LPS group) and FOS intervened group.According to the different concentrations of FOS,FOS intervened group was divided into high,middle and low dose FOS groups,which were FOS1 group,FOS2 group and FOS3 group respectively.The changes of TGF-β1 protein secretion was detected by the enzyme-linked immunosorbent-assay; The changes of TGF-β1 and Itg-β1 mRNA expression was detected by quantitative real-time RT-PCR.Results (1) TGF-β1protein secretion in rat GMC at 6h,12h,24h three time points:They were 958.55 ± 34.67 ( ng/L),1052.05 ±48.59( ng/L),1166.06 + 35.39 (ng/L) respectively in Control group.They were 1342.12 + 39.87 ( ng/L),1432.31 + 39.33 (ng/L) and 1 537.77 + 43.79 (ng/L) respectively in LPS group,which were higher significantly than those in Control group ( all P ＜ 0.01 ).They were 779.58 ± 48.64 ( ng/L),878.33 ± 29.50 (ng/L) and 962.57 ±31.94( ng/L) in FOS1 group,989.311±73.56(ng/L),1073.29±66.89(ng/L) and 1210.75 ±61.68(ng/L) in FOS2 group,1 253.78 ±45.32( ng/L),1 348.18 ±45.81 (ng/L) and 1450.06 ±46.24( ng/L) in FOS3 group respectively,which were lower significantly in all FOS intervened groups than that in LPS group (all P＜O.01).(2)TGF-β1 mRNA expressions in rat GMC at6h,12h,24h three time points were higher significantly than that in Control group.TGF-β1 mRNA expressions were lower significantly in all FOS intervened groups than that in LPS group.( 3 ) Itg-β1 mRNA expressiones in rat GMC at 6h,12h,24h three time points were higher significantly than that in Control group.Itg-β1 expressions were lower significantly in all FOS intervened groups than that in LPS group.Conclusions LPS can induce the increase of TGF-β1 secretion and mRNA expression.FOS can inhibit the TGF-β1 secrection and mRNA expession in GMC as dose-dependent manner,at the same time down regulated the Itg-β1 mRNA expression iuduced by LPS.All above supply the theoretical evidence for the renal protection of FOS by non-hemodynamics mechanism.
