Objective To explore the treatment effect and failure patterns associated with different clinical target volume on patients with esophageal carcinoma treated with 5-filed intensity modulated radiotherapy (IMRT), and to determine whether involved field irradiation (IFI) is practicable in these patients. Methods A total of 88 patients with esophageal carcinoma between January 2012 to June 2014 underwent IMRT in our hospital, were divided into IFI group and elective nodal irradiation(ENI) group according to the CTV range for a concurrent control study. Results One-year and two-year survival rate in IFI group and ENI group were 75.0%, 45.5% and 70.5%, 43.2% respectively (P > 0.05). Local failure rate in IFI and ENI groups was 27.3% and 22.7% respectively, distant metastasis failure rates 22.7% and 18.2% respectively and regional failure rate outside the radiation field 11.4% and 4.5%, which showed no statistical difference (P > 0.05). Subgroup analysis indicated failure outside the radiation field tended to increase for primary lesion located in the up thoracic or clinical stageⅠ in IFI group. The volume dose histogram of lung V5, V20, V30 and mean lung dose of ENI group were greater than that of IFI group, while V5 of lung and the mean lung dose had statistical difference. Conclusions The survival rate and local control rate have no significant differencein IFI group and ENI group, so IFI is feasible for some esophageal carcinoma, but it should be cautious to choose IFI for those primary lesion located in the up thoracic or clinical stageⅠ.

Objective To investigate the role of methylation of genomic DNA and connective tissue growth factor (CTGF) gene promoter in the pathogenesis of diabetic nephropathy (DN). Methods According to the WHO 1999 guideline for diabetes mellitus diagnosis and classification standard,90 patients diagnosed as diabetes mellitus and 30 healthy volunteers were enrolled in this study.All the participants were divided into diabetes mellitus without DN (DM) group (n=48),DN group (n=42) and healthy control group (n=30) accordingly.DNA was extracted from the peripheral blood and high pressure liquid chromatography (HPLC) was used to measure the overall methylation level of genomic DNA.The methylation status of CTGF gene promoter was determined by PCR and sequencing analysis.Serum CTGF protein level was measured by ELISA.Results The overall methylation level of genomic DNA was 5.23％±0.09％ for DN group,4.71％ ±0.03％ for DM group,and 4.37％±0.01％ for healthy control group,with no significant differences among three groups (all P＞0.05).The CTGF promoter methylation level in DN group (22.02％± 12.90％) was significantly decreased,compared to DM group (49.18％±8.01％,P=0.019) or healthy control group (72.18％±19.30％,P=0.000).Moreover,the serum CTGF protein level in DN group [(193.44±11.90) mg/L] was significantly increased,compared to DM group [(127.65±10.30) mg/L,P=0.031] and healthy control group [(95.84±5.10) mg/L,P=0.001]. Conclusion In DN patients,CTGF gene promoter methylation level is significantly decreased,but CTGF protein level is higher as compared to non-DN patients,which indicates that CTGF gene promoter demethylation may be involved in the pathogenesis of diabetic nephropathy.

Objective To investigate the association between Bsml polymorphism in vitamin D receptor (VDR) gene and diabetic nephropathy in Chinese Han population. Methods PCR-restriction fragment length polymorphism (PCR-RFLP) was used to test the genotype and allele frequency of Bsml in 304 patients with type 2 diabetes mellitus (DM group) and 100 healthy individuals (NC group).The DM group was further divided into non-diabetic nephropathy group (DN0 group,122 cases),minimal albuminuria group (DN1 group,87 cases),and mass albuminuria group (DN2 group,95 cases).Eighty-three DM patients without nephropathy for over 5 years were L-NDN subgroup,and 64 DM patients with nephropathy occurring within the first year were EDN subgroup. Results Genotype and allele frequency of BsmI polymorphism were significantly different between DM and NC group (x2=7.088,P=0.008;x2=5.865,P=0.015).BB+Bb genotype and B allele frequency were significantly higher in DN2 group than those in NC group (x2=14.287,P=0.000;x2=12.621,P=0.000) and DN0 group (x2=8.063,P=0.005;x2=8.173,P=0.004).BB+Bb genotype and B allele frequency were significantly higher in EDN group than those in L-NDN group (x2=7.228,P=0.007; x2=5.853,P=0.016).DN patients with allele B (BB and Bb genotypes)presented higher urinary albumin excretion rates compared with patients without allele B (bb genotype,P＜0.01).The genotype of BsmI was correlated with DN,and allele B was risk factor of DN occurrence and early onset (OR=2.004; OR=2.394). Conclusion VDR gene BsmI polymorphism is associated with DN,and the patients carrying allele B are more involved in mass albuminuria and eady onset of nephropathy.

Objective:To retrospectively analyze the treatment effect and the patterns of failure associated with different clinical target volume on patients with esophageal cancer treated with three dimensional conformal or intensity modulated radiotherapy, and to determine whether involved field radiotherapy is practicable in these patients. Methods:A total of 68 patients with esophageal squa-mous cell carcinoma between January 2007 to June 2011 in our hospital underwent three dimensional conformal or intensity modulated radiotherapy, according to the CTV range is divided into lymph involved-field group (involved field group) and lymph extended field group (extended field group). Results:In Involved field group and expand field group the survival rate of 1, 2 years were 59%, 41%and 61%, 39% respectively (P=0.56), and local control rates were 66%, 48% and 68%, 49% respectively(P=0.78). The total failure rates of involved field and the expand field were 63%and 66%(P=0.89). The local failure rate was 53%and 59%, distant metastasis failure rates were 47%and 44%, the regional failure rates were 11.8%and 7.5%in Involved field and the expand field, there were no difference in Statistics (P=0.39). The lung V10, V20, V30 and mean lung dose of extended field group were greater than that of the in-volved field group, while the mean lung dose and V10 has statistical difference. Conclusion:The involved field group was similar as the extended field group in the survival rate and local control rate, the regional recurrence and distant metastasis are the main cause of treatment failure, so the involved field radiotherapy is feasible for locally advanced esophageal carcinoma.

OBJECTIVETo investigate the differential expression of different types of Smads in keloids, normal scars and normal skins and its possible clinicopathological significance.

METHODSRT-PCR and Western blot methods were used to examine the expression of Smads mRNA and proteins level in 10 cases of keloid, in 10 cases of normal scar and in 10 cases of normal skin tissues and fibroblasts. Fibroblasts of keloid, normal scar and normal skin were cultured in vitro. The expression difference were compared and analyzed by t-test, there was statistical difference when P < 0.05.

RESULTSThe mRNA and protein expression of inhibitory Smad7 were significantly down regulated in keloid compared with normal scar (P < 0.05) and normal skin (P < 0.05). However, no significant difference of the mRNA and protein expression of Smad2, 3 and the protein expression of phosphorylation of Smad2, 3 in keloid, normal scar, normal skin tissues and fibroblasts.

CONCLUSIONSThe decreased expression of Smad7 in keloid might play a significant role in the increased TGF-beta1/Smads signal transduction, which can not be terminated by autologous negative feedback cycle.

OBJECTIVE: To investigate the possible role of Danshensu on fibronectin (FN) and collagen-I (Col-I) secretion induced by high glucose in human peritoneal mesothelial cells (HPMCs). METHODS: HPMCs were treated with high glucose and Danshensu at different concentrations. The mRNA expression of FN, Col-I, endothelin-1 (ET-1), and heme oxygenase-1 (HO-1) were examined by reverse transcription-polymerase chain reaction (RT-PCR). The protein expression of FN, Col-I HO-1 and ET-1 were analyzed by enzyme-linked immunosorbent assay or immunofluorescence method. RESULTS: The expression of protein and mRNA of FN and Col-I were attenuated by Danshensu in both dose-dependent and time-dependent manner. The mRNA and protein levels of ET-1 were decreased, and the mRNA and protein levels of HO-1 increased in the Danshensu groups in a dose-dependent manner compared with the high glucose group. The expression of ET-1 and HO-1 showed little difference in a time gradient of danshensu(P>0.05). CONCLUSION Danshensu can protect HPMCs through inhibiting the expression of FN and Col-I induced by high glucose, which is related to the suppression of oxidative stress.

BACKGROUNDSpinal cord injury (SCI) is a complex trauma that consists of multiple pathological mechanisms involving cytotoxic, oxidation stress and immune-endocrine. This study aimed to establish plasma metabonomics fingerprinting atlas for SCI using (1)H nuclear magnetic resonance (NMR) based metabonomics methodology and principal component analysis techniques.

METHODSNine Sprague-Dawley (SD) male rats were randomly divided into SCI, normal and sham-operation control groups. Plasma samples were collected for (1)H NMR spectroscopy 3 days after operation. The NMR data were analyzed using principal component analysis technique with Matlab software.

RESULTSMetabonomics analysis was able to distinguish the three groups (SCI, normal control, sham-operation). The fingerprinting atlas indicated that, compared with those without SCI, the SCI group demonstrated the following characteristics with regard to second principal component: it is made up of fatty acids, myc-inositol, arginine, very low-density lipoprotein (VLDL), low-density lipoprotein (LDL), triglyceride (TG), glucose, and 3-methyl-histamine.

CONCLUSIONSThe data indicated that SCI results in several significant changes in plasma metabolism early on and that a metabonomics approach based on (1)H NMR spectroscopy can provide a metabolic profile comprising several metabolite classes and allow for relative quantification of such changes. The results also provided support for further development and application of metabonomics technologies for studying SCI and for the utilization of multivariate models for classifying the extent of trauma within an individual.
