Objective To explore the effects of fibroblast transdifferentiation for myofibroblast (MFB) in the pathogenesis of systemic sclerosis (SSc) and to explore the antifibrotic mechanism of interferon γ (IFN-γ) in SSc.Methods The fibroblasts derived from the skin lesions of SSc patients and healthy adult controls were cultured in vitro and the MFB proportion in fibroblasts was examined by qualitative and quantitative α-smooth muscle actin (α-SMA) detection.By adding IFN-γ to the culture system with several doses,the influence on fibroblast proliferation and transdifferentiation for MFB in SSc was observed with MTT and enzyme linked immunosorbent assay (ELISA) respectively.Differences in the means of two independent samples were tested by Student' t-test.The means among multiple independent samples were com-pared by ANOVA.Results The means of positive α-SMA in SSc fibroblasts were higher than those in the controls (P＜0.01).With extended culture time,α-SMA levels of the two groups all increased gradually (P＜ 0.01 all),but there were higher α-SMA levels in SSc fibroblasts (24 h:130±19,48 h:183±21,72 h:249± 22) than those in controls (24 h:98±21,48 h:143±16,72 h:174±19) (P＜0.05 all).Although fibroblast proliferation and α-SMA levels were not influenced after adding of IFN-γ 10 U/ml (P＞0.05 all),but IFN-γ at concentration of 100 U/ml and 1000 U/ml could obviously repress fibroblast proliferation and α-SMA levels (P＜0.05 all),and 1000 U/ml had the strongest inhibiting effect at 24,48,72 h.Conclusion The fibroblasts in the skin of SSc patients have a strong potency to transdifferentiate to MFB.Early appropviate dose of IFN-γ could repress fibroblast proliferation and transdifferentiation in SSc.

Objective To comparative analysis the effect of radiotherapy,thermoradiotherapy and chemora-diotherapy on esophageal cancer.Methods 120 patients with esophageal carcinoma were selected and randomly divided into the radiotherapy group,thermoradiotherapy groupand chemoradiotherapy group by digital table method, with 40 cases in each group,which were treated with radiotherapy alone,thermoradiotherapy alone and radiotherapy combine with chemotherapy respectively.The effects of treatment of the three groups were compared.Results The main toxic reaction in the three groups during the treatment for adverse reaction were digestive system reaction,hema-tologic toxicities and radioactive esophagitis.The incidence of toxic reaction of the three groups were not statistically significant(P >0.05).Total response rate of simple radiotherapy group,the thermal radiation group,chemoradiothera-py group were 52.5%,75.0% and 85.0%.,The total remission rate of chemotherapy group was higher than those of the radiotherapy group and the thermal radiation group(χ2 =5.218,3.857,all P <0.05).Conclusion The different treatment methods of esophageal cancer can obtain certain curative effect,but there are some adverse reactions.Among different treatment methods,radiotherapy and chemotherapy in the treatment of esophageal carcinoma can get better effect than the radiotherapy and chemoradiotherapy.

Objective To observe the treatment effect of Shah Mette Lo/fluticasone inhalation(Seretide)for stable stage of chronic obstructive pulmonary disease (COPD).Methods 50 patients with COPD were randomly divided into treatment group and control group.The treatment group was given Seretide (specifications of 250μg)1 -2 ceiling/time,2 times/day,after 24 weeks of treatment,the control group was given 2mg of regular salbutamol com-bined with budesonide 1mg atomization inhalation,2 times daily.The clinical symptoms were compared before and aftertreatment.Results In the treatment group,acute seizure frequency was significantly reduced,cough,wheezing singing decreased or disappeared,self -care ability improved,the control group had no obvious change.The control group:before treatment FEV1 (1.1 ±0.4)L;FEV1 % predicted value(22.5 ±5.1 )%;FEV1 /FVC%:(25.3 ±5.8)%;after treatment FEV1 (1.5 ±0.7)L;FEV1 % predicted value(29.4 ±6.2)%;FEV1 /FVC%:(32.8 ±6.6)%.The treatment group:before treatment FEV1 (1.1 ±0.6)L;FEV1 % predicted value (24.5 ±5.6)%;FEV1 /FVC%:(26.7 ±6.6)%;after treatment FEV1 (1.7 ±0.6)L;FEV1 % predicted value(33.4 ±7.8)%;FEV1 /FVC%:(37.8 ± 8.6)%.Conclusion In patients with stable COPD inhaled Seretide treatment can significantly improve lung func-tion,and it is better than sardine an alcohol combined with budesonide inhalation therapy.

Objective To evaluate the role of sonic hedgehog (SHH) signaling pathway in spinal neurons in morphine tolerance (MT) in mice.Methods Pathogen-free healthy female Kunming mice,weighing 20-25 g,aged 8-10 weeks,were used in the study.MT was induced with morphine 10 mg/kg injected subcutaneously twice a day for 7 consecutive days.The experiment was performed in two parts.Experiment Ⅰ Forty-eight mice were randomly assigned into 2 groups:control group (group C,n =8) and MT group (group M,n=40).The thermal pain threshold (TPT) was measured at 1 day before morphine injection and 1,3,5,7 and 14 days after the end of injection.Eight mice in each group were sacrificed at 2 h after measurement of TPT at each time point after the end of injection in group M or at 2 h after the last measurement of TPT in group C,and the lumbar segment (L4-6) of the spinal cord was removed.Experiment Ⅱ Forty-eight mice were randomly assigned into 6 groups (n=8 each):SHH inhibitor cyclopamine plus MT group (group CP+M),cyclopamine solvent plus MT group (group D1 +M),SHH agonist SAG plus MT group (group SAG+M),SAG solvent plus MT group (group D2+M),MT plus cyclopamine group (group M+CP) and morphine plus cyelopamine solvent group (group M+D1).At 15 min before morphine injection,cyclopamine 10 mg/kg was injected subcutaneously in group CP+M,and SAG 5 mg/kg was injected subcutaneously in group SAG+M.Cyclopamine 10 mg/kg was injected subcutaneously once a day during the 1-3 days after the end of morphine injection in group M+CP.The TPT was measured before injection of morphine,at 30 min after the first injection of morphine every day and at 1-3 days after the end of morphine injection.The animals were sacrificed at 2 h after the last measurement of TPT,and the lumbar segment (L4-6) of the spinal cord was removed for determination of the expression of SHH signaling pathway-related proteins SHH,ptch1,smo,gli1 and gli3 using Western blot.Results Experiment Ⅰ Compared with group C,the TPT was significantly decreased at 1 and 3 days after the end of morphine injection (P＜0.05),no significant change was found in TPT at 5-14 days after the end of morphine injection (P＞0.05),and the expression of SHH,smo and glil at 1-5 days after the end of morphine injection,of ptchl at 1 and 3 days after the end of morphine injection and of gli3 at 7 days after the end of morphine injection was up-regulated in group M (P＜0.05).Experiment Ⅱ Compared with group D1+M,the TPT was significantly increased,the expression of SHH,ptchl,smo and glil was down-regulated,and gli3 expression was up-regulated in group C P+M (P＜0.05).Compared with group D2+M,the TPT was significantly decreased,the expression of SHH,ptch1,smo and glil was up-regulated,and gli3 expression was down-regulated in group SAG+M (P＜0.05).There was no significant difference in the parameters mentioned above between group M+CP and group M+D1 (P＞0.05).The TPT was significantly lower on 3rd-7th days after beginning of morphine injection and 1-3 days after the end of morphine injection than at 30 min after the first injection of morphine in group CP+M (P＜0.05).Conclusion The mechanism underlying the development of MT is partially related to activation of SHH signaling pathway in spinal neurons of mice,however,the maintenance mechanism has no marked relationship with it.

ObjectiveTo assess the differential diagnostic value of serum intestinal fatty acid binding protein (I-FABP)in distinguishing intestinal ischemia patients from acute abdomen patients.MethodsA total of 151 patients with acute abdomen and 17 healthy controls from the PLA General Hospital were enrolled from November,2009 to August,2011. Serum I-FABP levels were measured by ELISA.According to the ROC curve,the cut-off value,sensitivity,specificity,positive likelihood ratio (PLR),negative likelihood ratio ( NLR),positive predietive value (PPV) and negative predictive value (NPV) were calculated. ResultsOf the 151 acute abdomen patients,there were 24 intestinal ischemia patients and 127 without intestinal ischemia.Serum I-FABP level in intestinal ischemia group [( 109.67 ±48.82) μg/L]was significantly higher than those in patients without intestinal ischemia [(36.78 ± 11.25) μg/L]and healthy controls[(8.33 ±6.25) μg/L]( all P values ＜0.01 ).The serum I-FABP cut-off value for the diagnosis of intestinal ischemia was 87.52 μg/L.Serum I-FABP was efficient in terms of sensitivity (0.762),NPV(0.963),PLR(3.05) and NLR (0.24) in the diagnosis of intestinal ischemia.ConclusionI-FABP is potentially useful for discriminating intestinal ischemia from acute abdomen.

Objective To evaluate the clinical effects of platelet-rich plasma in treatment of DeepⅡburn wounds. Methods Sixty eight cases of inpatients with Deep Ⅱburns were selected, whose age were from 1 to 65 years and their burn areas were between 5%~62%of total body surface area (TBSA). Deep gradeⅡburn of each sample was divided into two parts. Part A was the treatment group and part B was the control group.The burn wounds in the treatment group were treated with platelet-rich plasma and the counterpart in the control group were treated with SD-Ag. Healing time ,recovering rate and the frequency of dressing changes,frequency of changing the most innerlayer gauze and the rate of wound infection were also analyzed. Finally the laboratory abnormalities and adverse effect were monitored regularly. Results The healing time of the treatment group (16.5±3.1 ) d was shorter than that of the control group (19.5±3.8 ) d. The recovering rate of the treatment group was higher than that of the control group on the 14th and 17th day after treatment. There were statistically sig?nificant differences between these two groups (P<0.05). After two weeks’treatment, the internal and external dressing per?meability into wet gauze layers were 20.6 ± 1.7, which were significantly decreased than that in the control group 23.3 ± 5.9. The frequency of dressing changes was(7.2±1.1)times in treatment group versus(9.2±1.4)times in control group and the frequency of changing the inner most layer gauze was( 2.3±0.6)times in the treatment group versus(5.3±1.3)times in con?trol group. There were 5 inflammation reaction cases in the treatment group, but 13 cases in the control group. However, there was no statistic significance between the two group in the outcomes of bacterial culture, the laboratory abnormalities and the adverse effect. Conclusion Platelet-rich plasma can remarkably shorten the healing time,improve healing rate,re?duce frequency of dressing change and promote wound healing for deepⅡburn wound. PRP is a potential safety reagent in treating deepⅡburn wound.
