Objective To investigate the principles of combined traditional Chinese and western medicine treatment of early postoperation inflammatory small bowel obstruction(EPISBO).Methods 93 cases of EPISBO were randomly divided into two groups including group A,47 cases received combined traditional Chinese and west- ern medicine treatment,and group B 46 received only western medicine treatment.Results 93 patients were all cured through nonsurgical treatment.The combined traditional Chinese and western medicine treatment was better in symtom improvement and reduce of expense.Conclusion The principle treatment of EPISBO is mainly nonsurgical. The traditional Chinese medicine and somatostatin are very important.

Objective To illustrate the evaluation effect of bivariate analysis of sensitivity and specificity meta-analysis model in diagnosis test to provide basis for selecting better evaluation method of diagnostic test.Methods Bivariate model was presented by reanalyzing the data from a published meta-analysis of two diagnostic techniques in diagnosis of schistosomiasis japonica.Results The bivariate model could directly provide summary estimates of(logit)sensitivity,specificity and DOR with corresponding 95% CI for two diagnostic tests(IHA and ELISA).Also,it could elicit any significant difference that existed among sensitivity,specificity and DOR between the two diagnostic methods,and incorporate any correlation that existed between sensitivity;specificity.Conclusion The bivariate model preserves the two dimensional nature of the original data,and separates effects of sensitivity and specificity,which is more rational than a net effect on diagnostic odds ratio scale as in SROC approach.The bivariate model is appropriate and agile,and can be used as an extension and improvement of the traditional SROC method.

Objective The study of loss of heterozygosity (LOH) on chromosome 1p36 was performed to locate the deletion areas probably harboring tumor suppressor genes in invasive ductal breast carcinoma not otherwise specified (IDC NOS).Methods Eighty paired breast cancer/normal tissue DNA samples were examined for LOH on chromosome lp36 using eight polymorphic microsatellite (MS) loci.The PCR products were electrophoresed on 8％ denatured polyacrylamide gel and stained using silver staining.Finally,the data were analysed and compared with the clinicopathological parameters using statistical analysis.Results In 80 IDC NOS,LOH was identified in 45 cases (56.3 ％) at least in one MS locus.MS locus D1S1310 showed the highest rate of LOH [35.7％ (25/70)].Conclusion Chromosome 1p36 might be the highly deleted region.The results of this study indicate that the chromosomal regions 1p36.23-33 might contain tumor suppressor genes associated with human breast carcinomas.

Objective To compare the diagnostic value of DSA with that of Gd-EOB-DTPA-enhanced MRI for postoperative recurrent tiny hepatocellular carcinoma (HCC) lesions.Methods The clinical data of a total of 38 patients,who were admitted to authors' hospital during the period from September 2011 to March 2016 as clinically they were suspected to have postoperative recurrent tiny HCC lesions,were retrospectively analyzed.DSA,DSA plus lipiodol CT scan and Gd-EOB-DTPA-enhanced MRI were performed in all patients.The positive and negative diagnosis rates were compared among different examination methods,the diagnostic sensitivity and specificity were calculated.The imaging diagnosis of each patient was made by two associationchief radiologists independently,both the pathological findings from surgery or puncture biopsy and the 6-month follow-up results were taken as the final diagnosis basis.Results A total of 47 lesions were detected in the 38 patients.The diameter of the lesions was 0.5-2.0 cm,with an average of (1.2+0.8) cm.Of the 47 lesions,41 were proved to be recurrent tiny HCC lesions.Among the 41 lesions,22 had pathological evidence,and the remaining 19 lesions were confirmed through clinical follow-up.Six lesions were non-HCC focus,which were proved by clinical follow-up.For all lesions,the diagnostic sensitivity and specificity were 72.2％ and 80.0％ respectively by conventional DSA,which were 90.2％ and 100％ respectively by DSA plus lipiodol CT scan,and were 95.1％ and 100％ respectively by Gd-EOB-DTPA-enhanced MRI.Statistical analysis indicated that significant differences in diagnostic sensitivity and specificity existed between conventional DSA and DSA plus lipiodol CT scan as well as between conventional DSA and Gd-EOB-DTPA-enhanced MRI (P＜0.05),while the differences in diagnostic sensitivity and specificity between DSA plus lipiodol CT scan and Gd-EOB-DTPA-enhanced MRI were not statistically significant (P＞0.05).Conclusion For the detection of postoperative recurrent tiny HCC lesions,DSA plus lipiodol CT scan has quite the same diagnostic value as Gd-EOB-DTPA-enhanced MRI does.For patients who are not suitable to receive MRI examination,the use of DSA plus lipiodol CT scan,as an alternative means of inspection,should be taken into consideration.

Objective To screen and analyze nucleotide variants in 5'-untranslated region(5'-UTR)in voltage-gated sodium channel α1-subunit gene(SCN1A)in patients with Dravet syndrome and to evaluate the association of the variants with disease.Methods Peripheral blood of 24 patients with Dravet syndrome and 100 unrelated normal persons were collected and genomic DNA was extracted.PCR-sequencing of SCN1 A 5'-UTR in these DNA was performed.To evaluate the possibility of mutation inducing disease,bioinformatics analysis was applied to analyze the conservation of the sequences around the mutation site and predict the potential transcription elements.Results The nucleotide variant of 166.642.520G→A in exon 2 was identified in two patients,but not in normal controls.The mutation was a de novo mutation in a patient with early-onset.In the second proband,the mutation was also carried by his clinically asymptomatic mother.The nucleotide site 166.642.520 was moderately conserved in mammals(62.5%).The average nucleotide identity rate between human and other mammals species in the region adjacent to 166.642.520 was 88.5%.Two potential transcription regulatory elements were predicted on the sequence with the mutation of 166.642.520G>A,and only one on the sequence with wild-type.Conclusions The mutation 166.642.520G>A may be associated with Dravet syndrome and further studied should be performed to verify it and demonstrate its pathogenic mechanisms.

Objective: To examine the cytotoxic properties of both the kenaf (Hibiscus cannabinus L.) seed extract and kenaf seed oil on human cervical cancer, human breast cancer, human colon cancer and human lung cancer cell lines.Methods:kenaf seed oil on human cancer cell lines was evaluated by using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide and sulforhodamine B assays. Cell morphological changes were observed by using an inverted light microscope.Results:The in vitro cytotoxic activity of the kenaf (Hibiscus cannabinus L.) seed extract and cancer cell lines. Morphological alterations in the cell lines after KSE and KSO treatment were observed. KSE and KSO possessed effective cytotoxic activities against all the cell lines been selected.Conclusions:KSE and KSO could be potential sources of natural anti-cancer agents. Further The kenaf seed extract (KSE) exhibited a lower IC50 than kenaf seed oil (KSO) in all of the investigations on using kenaf seeds for anti-proliferative properties are warranted.

SW872 cells were cultured in vitro with oleic acid and differentiated into mature adipocytes. The role of interleukin-6(IL-6)in the secretion of acylation-stimulating protein(ASP)in mature SW872 adipocytes was observed.The results suggested that IL-6 significantly inhibited ASP secretion into the media in a dose-and time-dependent manner in mature SW872 adipocytes.

To investigate the genetic diversity among wild Dipsacus asperoides in China, 66 germplasmic resources of D. asperoides were analyzed by Start Codon Targeted Polymorphism (SCoT) molecular markers. Genetic distance was calculated by TREECONW software and the systematic diagram of genetic relationship was clustered by UPGMA method. The results showed that the totals of 181 bands were detected using 20 primers , among which 109 were polymorphic bands. The average percentage of polymorphic bands was 60.13%. Genetic distance changed from 0.030 6 to 0.181 4. The clustering results showed that there was no significant correlation between the classification of the wild D. asperoides and their geographical origin. The relatively high genetic diversity of D. asperoides provides the basis for breeding new varieties.
