ABSTRACT

Objective To investigate the association between microvariants at locus DYS570 and Y-SNPs haplogroup.Methods 89 Y-SNPs and 34 Y-STRs in AIYSNP42,AIYSNP47 and YfilerTM Platinum kits were used to detect the genotype of 116 microvariants at locus DYS570 in Kunming,and the Set-B kit was used to detect the core repeat sequences of the DYS570 locus.The data were statistically analyzed by direct counting method.Then,a network map was drawn by Network 10.2,in order to visualize the genetic information of the sample.Results The results demonstrated that 111 DYS570/18.3-21.3 samples had a core repeat sequence of TTT[TITC]18-21,belonging to subgroup O2a2b1a1a1a4-F14494.A DYS570/20.3 sample had a core repeat sequence of[TTTC]15TTC[TTTC]5,belonging to O2a1b1a1a1a1e-F1365 subgroup.A DYS570/17.1 sample had a core repeat sequence of[TTTC]17 T,belonging to the O2a1b1a1a1a-F11 subgroup.Three DYS570(19.2)samples had[TTTC]3 TT[TTTC]16,belonging to the D1a1a-M15 haplogroup.Conclusion The results indicated that the microvariant with the same core repeat structure at locus DYS570 was associated with haplogroups,and the ancestry origin of samples can be inferenced from microvariant characteristics during the practice of forensic medicine.

ABSTRACT

Objective To investigate the association of the DYS527a/b and DYF387S1a/b multi-allele pattern with Y-SNP haplogroups.Methods Samples from 295 unrelated males who carrying the DYS527a/b multi-allele pattern were amplified by the YFilerPlus? kit.The genotypes of their frequency distributions,including three multi-copy loci(DYS527a/b,DYF387S1a/b,DYS385a/b)and other single-copy loci were obtained.The DYS527a/b multi-allele pattern and their haplotypes were examined for the associations with Y-chromosome haplogroups using the AIYSNP42 kit,which contains 42 Y-SNP loci.Based on the above results,the association between the DYS527a/b multi-allele patter and its constituent Y-STR haplotypes and related haplogroups was discussed.Results Among the 295 samples,the DYS527a/b tri-allele pattern and tetra-allele pattern accounted for 97.29%and 2.71%respectively,while the DYF387S1a/b tri-allele pattern and tetra-allele encompassed 54.24%and 4.75%.Null allele was detected in DYS448 in 13.22%of the samples.Here,7 Y-SNPs were deticted such as O-M175 and C-M131 which encompassed 45.76%and 45.08%.The haplogroups of R1-M173,N-M231,D1-M174,J-M304 and F-M89 were less than 13 cases,with frequencies ranging from 4.41%~0.34%.There were Y-STR genotypes differences among haplogroups,as haplogroup O-M175 was represented by 4 genotypes of Y-STR profiles characterized by DYS385a/b(12/12,as well as 12/17,12/18,12/19),DYS392(13),DYS593(16)and DYS393(12),and haplogroup C-M130 was characterized by DYS527a/b(19/20/21),DYS385a/b(11),DYS593(17),DYS390(23),Y_GATA_H4(11),and DYS444(13)and so on.Conclusion The DYS527a/b multi-allele pattern is frequently observed in the Kunming population with haplogroup C-M130.In the samples from haplogroups O,C,R1 and N,the DYS527a/b and DYF387S1a/b haplotypes frequently exhibit the multi-allele pattern.Given the frequencies of different haplogroups and the association between Y-SNP haplogroups and Y-STR loci,it could be helpful to look for more details in the paternal lineage search.

ABSTRACT

Objective To explore the effect of motivational interviewing on the self-care of type 2 diabetic patients . Methods Totally 96 inpatients with type 2 diabetes were randomly divided into the control group and the intervention group , each group containing 48 patients. The control group received routine diabetes education, while the intervention group received face-to-face and one-by-one motivational interviewing intervention for three months. The patients′self-care level were evaluated by using diabetes self-care scale after intervention. Result After intervention, the score on the self-care behaviors including diet control, exercise therapy, medication , blood glucose monitoring and foot care were significantly higher in the intervention group than those in the control group (P < 0.01). Conclusion Motivational interviewing can improve the ability of type 2 diabetic patients to control the glycemic level.

ABSTRACT

Objective To establish the method and assess the safety,feasibility and clinical efficacies of percutaneous transhepaticcontrast-enhancedcholangio-ultrasonography(PTCECUS).Methods Twenty-one patients aged(58.5±16.65)years(range 27-93)with biliary obstruction or stricture underwent percutaneous transhepatic cholangiodrainage or ch01ecystodrainage.A dose of more than 50 ml of 0.94% Sono Vue(Bracco,Itay)solution was injected into their bile ducts(n=17)and cholecysts(n=4)through the drainage catheter.Their biliary tracts,cholecysts and duodenums were scanned under contrast pulsed sequencing mode(CPS,Sequoia 512,Siemens)to achieve related contrast-enhanced ultrasonograms.Severity of biliary obstruction were assessed according to the PTCECUS findingswith a comparison toconventionalultrasonography(CVUS),magnetic resonance cholangiopancreatography(MRCP)and percutaneous transhepatic cholangiography(PTC)in a part of the patients.Results①PTCECUS gave rise to good-quality contrast-enhanced uhrasonograms of biliary tracts.②PTCECUS was superior to CVUS and in consistence with MRCP and PTC in evaluating the severity of biliary tract obstruction.This method helped to make a proper design for biliary drainage.③PTCECUS was more efficient than PTC in that PTC had the patients receive transhepatic puncture and cholangiography in separated departments.④Neither any complications immediate from transhepatic puncture and administration of SonoVue inall the 21 patients,nor those 1 to 8 months late during ultrasound follow up in 14 patients were found.Conclusions PTCECUS,characterized in bettering the display of biliary tracts,especially the severity of obstruction of biliary tracts,is safe through the procedure and valuable in supervising biliary drainage against obstructive jaundice.

ABSTRACT

Objective: To investigate changes of the endothelin-1(ET-1) and its receptor (endothelin receptor subtype A, ET AR ) mRNA expression in some organs(kidney, lung and small intestinal mucous membrane) in the sepsis and septic shock rats. Methods: Twenty-four male rats randomized into sepsis group, septic shock group, control and normal group was infused with endotoxin(LPS) via indwelling right atria catheters except normal and control group. RT-PCR was used to detect kidney, lung and small intestinal mucous membrane tissue mRNA expression of the ET-1 , ET AR and glucose-6-phospho dehydrogenase(G-6-PD) in every group.Serum BUN, Cr, ALT and A were determined. The arterial oxygen tension (PaO 2) and arterial carbon dioxide partial pressure(PaCO 2)were measured in every group. Results: ET-1 mRNA and ET AR mRNA expression in the sepsis group and septic shock group were significantly higher than in normal group. There were significant differences between the normal/control group and sepsis/shock group in BUN,Cr,ALT,PaO 2 and PaCO 2. Conclusion: A higher expression of ET-1 mRNA and ET AR mRNA may be one of the startup factors on multiple organ dysfunction syndrome (MODS) and may play an important role on pathogenesis in sepsis and septic shock.

ABSTRACT

Objective: To investigate the role of TNF-? and IFN-? in modulation of Fas ligand(FasL) expression in human colon carcinoma cells. Methods: A total of 6 human colon cancer cell lines were examined for FasL protein expression and for TNF-? and IFN-? modulation of FasL expression by Western blot method. Results: The results showed that FasL protein was expressed in all of these 6 cancer cell lines.FasL expression was up-regulated by TNF-? and IFN-? for 10 h in DLD-1 colon cancer cells; FasL expression was also up-regulated by TNF-? and IFN-? as well as PMA plus ionomycin for 10 h in SW620 cells, and further up-regulation was got by TNF-? and PMA plus ionomycin for 48 h in SW620 cells,whereas slight up-regulation was obtained by IFN-?. Conclusion: These data suggest that TNF-? and IFN-? may enhance FasL expression in tumor cells and may facilitate to escape from the immune surveillance of the host.

ABSTRACT

Objective: To investigate the expression and function of Fas ligand (FasL) in human colon carcinoma cells. Methods: A total of 6 human colon cancer cell lines were examined for FasL mRNA and protein expression, Fas-dependent cytotoxicity and its modulation were detected by using RT-PCR, Western blot and 3H-TdR release assay. Results: FasL mRNA and protein was expressed in all of these 6 cancer cell lines RPMI 4788, HCT-116, DLD-1, LoVo, WiDr and COLO 320DM. Fas-dependent cytotoxicity to hFas transfectant was exerted in part of these cancer cells, such as DLD-1, LoVo and WiDr. The cytotoxicity was significantly enhanced by PMA and ionomycin. Conclusion: These data suggest that functional FasL is expressed, at least in part, in human colon cancer cell lines and may help to escape from immune surveillance of the host.

ABSTRACT

Objective To investigate the cause and management of postsplenectomy fever in portal hypertensive patients . Methods The clinical data of 295 portal hypertension patients undergoing splenectomy from 1990 to 2003 were reviewed. Among these,80 patients suffered from a continuous fever higher than 38.5℃ for more than 2 weeks postoperatively. Results Except for two patients with unknown cause, 78 of 295 patients with continuous fever were caused by complications such as splenoportal thrombosis(35 cases), infection of hematocele or hydrops in splenic recess(20 cases), left subphrenic infection(7 cases), pneumonia and hydrothorax or empyema(5 cases), 3 cases each of postoperative abscess of tail of pancreas,winary tract infection and inteclion of surgical incision, 1 case of leakage of esophageal anastomosis and intraabdominal infection in 1 case. The lasting fever was related to the grade of liver function(P0.05). Conclusions Splenoportal thrombosis, and hematocele, hydrops or infection in the splenic recess were the main causes of persistent fever after splenectomy. Prevention and treatment of infection and amelioration of hepatic function will help to reduce the rate of postoperative continuous fever.
