Objective To explore the influence of self-management education on quality of life of patients with deep vein thrombosis. Methods 60 cases of deep vein thrombosis patients were randomly divided into the experimental group and the control group with 30 cases in each group, two groups basically received the same medication treatment, the control group held conventional health education, The experimental group implemented self-management education.Life quality was compared before education and 3 months after education was compared between the two groups. Results Before self-management education, the scores of quality of life of the two groups showed no difference; after three months of selfmanagement education, the score of body's function, psychological function, social function and total score of quality of life were obviouly different.However, there were no significant differences in material life. Conclusions Self-management education can improve the quality of life of patients with lower extremity deep vein thrombosis.

OBJECTIVEThis study aimed to investigate the effects of hirudin on the expression of transforming growth factor (TGF-β1) and basic fibroblast growth factor (bFGF) in human gingival fibroblasts (HGFs) in vitro, as well to explore its func- tion in the mechanism of gingival remodeling.

METHODSAfter culturing was performed with classic tissue-explant method, HGFs were derived from normal gingival and gingival hyperplasia tissues followed by orthodontic treatments with different concentrations of hirudin. The mRNA and protein expression levels of TGF-β1 and bFGF were respectively detected by real time quantity polymerase chain reaction and immunocytochemistry.

RESULTSCompared with normal HGFs, TGF-β1 expression promoted collagen synthesis of fibroblasts, whereas bFGF collagen synthesis was decreased in hyperplasia HGFs without hirudin (P < 0.05). Hirudin significantly upregulated the expression levels of bFGF but downregulated TGF-β1 in hyperplasia HGFs (P < 0.05).

CONCLUSIONOrthodontic force may influence the balance of collagen synthesis and degradation in HGFs. Hirudin may modulate the balance of HGF collagen metabolism, thereby promoting gingival remodeling.

Objective To analyze the complications,treatments and prognosis of simultaneous pancreas-kidney transplantation,especially on surgical complications and treatments.Method The causes and outcomes of surgical treatment in 70 cases of simultaneous pancreas-kidney transplantation performed between Dec.1999 and June 2012 were retrospectively analyzed in our center.Result Sixteen patients (22.9％) underwent one or more reoperations.The causes for reoperation were as follows:2 cases of hematuria,4 cases of abdominal hemorrhage,4 cases of abdominal infection,4cases of pancreatic thrombosis,2 cases of renal graft's artery rupture,1 case of renal allograft rupture,1 case of intestinal fistula,and 1 case of pancreatic fistula.Eight pancreas grafts were lost in the first year.Pancreatectomy was performed on the other 5 cases:4 cases of pancreatic thrombosis,1 case of intestinal fistula,accounting for 43.8％ of the patients subject to reoperation.The recipients,kidney,pancreas survival rate in reoperation group at 1 year was 87.5％,75％,and 56.3％ respectively; and that in control group at 1 year was 98.1％,98.1 ％,and 98.1 ％ respectively.There was significant difference in kidney survival rate (P＜0.01,chi-square =6.79),and pancreas survival rate (P＜0.01,chi-square =17.47) between two groups.Conclusion Although simultaneous pancreas-kidney transplantation provides a successful and effective treatment for diabetics with end-stage renal disease,surgical treatment due to complications is still an important factor in short-term survival on the grafts.

AIM: To investigate the effects of rosiglitazone on fibroblast-like synoviocyte ( FLS )-induced osteoclastogenesis in rheumatoid arthritis ( RA) and the related mechanism.METHODS: RA-FLS were cocultured with peripheral blood monocytes from healthy volunteers in the presence of macrophage colony-stimulating factor ( M-CSF) and rosiglitazone.Osteoclasts were assayed by tartrate-resistant acid phosphatase ( TRAP) staining.Resorption lacunae area was identified by toluidine blue staining and quantified by image analysis software.The mRNA expression of RANKL and OPG was evaluated by real-time PCR, and the protein levels of RANKL, OPG, p-ERK, p-p38 and p-JNK were measured by Western blot.RESULTS:Compared with control group ( without rosiglitazone treatment) , rosiglitazone at concentration of 15 μmol/L significantly decreased the number of osteoclasts (P<0.01) and resorption lacunae area (P<0.05).The expression of RANKL at mRNA and protein levels was significantly down-regulated by rosiglitazone at concentration of 15μmol/L, while the mRNA and protein expression of OPG was up-regulated (P<0.01).Rosiglitazone (15 μmol/L) sig-nificantly decreased the protein level of p-ERK ( P<0.05 ) , but not the protein level of p-p38 or p-JNK ( P>0.05 ) . CONCLUSION:Rosiglitazone inhibits RA-FLS-induced osteoclast formation and its resorption activity by down-regulating RANKL expression and ERK phosphorylation, suggesting that rosiglitazone may inhibit RA osteoclastogenesis and bone re-sorption.

Objective To investigate the clinical significance and mechanism of WW domain containing oxidoreductase (WWOX) gene and p73 gene abnormal expression in acute lymphocytic leukemia (ALL).MethodsCase-control study was used in the research.Forty-eight cases of bone marrows from ALL patients were collected,including 32 cases newly diagnosed,11 cases with complete remission and 5 case with relapse.Thirty-one cases of bone marrows from non-leukemia patients were used as control group.All the samples were collected from First Affiliated Hospital of Guangxi Medical University from July 2010 to July 2011.The doctors punctured patients' bone marrows 3 milliliters from the left of posterior superior iliac spine.Samples were bottled up with EDTA anti-coagulation tube.1 milliliter bone marrow was used to extract genome RNA with purity from 1.8 to 2.0.And then,the level of WWOX and p73 gene transcripts were tested immediately using reverse transcriptase-polymerase chain reaction (RT-PCR).Meanwhile genome DNA was also extracted from the other 2 milliliter bone marrow with purity from 1.7 to 1.9,which was used to detect the promoter methylation of WWOX gene and the first exon methylation of p73 gene by methylation PCR (MS-PCP).x2 test and Fisher's exact test were used to compare tbe methylation status of WWOX and p73 gene.Results In 31 controls,expression of WWOX and p73 gene mRNA was 94.00％.The total expression frequency of WWOX gene mRNA in 48 ALL samples was 48.00％ (23/48),much lower than control (x2 =17.434,P =0.000 ).There was significant difference (x2 =10.471,P =0.001 ) between newly diagnosed cases 34.38％ ( 11/32),complcte remission cases (90.91％,10/11 ) and control.The total expression frequency of p73 gene mRNA in 48 ALL samples was 56.00％ (27/48),much lower than control (x2 =12.697,P =0.000).There was significant difference (P =0.012 ) between newly diagnosed cases 43.75％(14/32) and complete remission cases 90.91％(10/11).It was unmethylation in 31 controls.The total methylation frequency of WWOX gene promoter region in 48 ALL samples was 44.00％(21/48),much lower than control (x2 =18.473,P =0.000).There was significant difference (P =0.012) between newly diagnosed cases 56.25％ (18/32),complete remission cases 9.09％ (1/11 ) and control.The total methylation frequency of p73 gene the first exon region in 48 ALL samples was 35.00％(17/48),much lower than control (x2 =13.990,P =0.000).There was significant difference (P =0.033) between newly diagnosed cases 46.88％ (15/32),complete remission cases 9.09％ ( 1/11 ) and control.There was a negative correlation between the expression of WWOX gene mRNA and its methylation status(r =- 0.678,P =0.000),the same as p73 gene ( r =- 0.577,P =0.000).ConclusionsThe abnormal methylation of WWOX and p73 gene may be the major mechanism of gene silence in ALL,which leads to no expression of WWOX mRNA or p73 mRNA.And the abnormal methylation of WWOX and p73 gene may be relevant with the process of occurrence and development in ALL.It may be an effective and significant to detect methylation status of WWOX gene and p73 gene for the diagnosis and treatment of ALL patients.(Chin J Lab Med,2012,35:820-825)

Objective To analyze the complications, treatments and prognosis of simultaneous pancreas-kidney transplantation. Methods Forty cases of simultaneous pancreas-kidney transplantation performed between Dec. 1999 and Jan. 2010 in our center were retrospectively analyzed. Results Regarding surgical complications, 4 cases had severe hematuria after operation,which needed clinical intervention, including 1 patient receiving catheterization in duodenum to stop bleeding. Two patients were treated with continuous bladder irrigation, and the remaining one received surgical haemostasis because of donor's duodenum and bladder anastomotic artery hemorrhage.Abdominal hemorrhage occurred in 4 patients, including pancreatic hemorrhage in 3 cases and duodenal muscularis hemorrhage in one case. All of them received surgical treatment for hemostasis.Abdominal infection occurred in 8 cases: one died of multiple organ failure, 2 cases were cured after drainage of abscess, 2 cases underwent surgical removal of abscess, and 3 cases were cured after antibiotic therapy. In one case of postoperative anastomotic leakage, pancreas was resected. Four cases of postoperative ileus were cured by continuous clysis with traditional Chinese medicine. Seven cases had pulmonary bacterial infections, including one cases associated with fungal infection. They were cured by the anti-infective treatment. Other complication included poor healing in 5 cases and urinary infection in 2 cases. After combined simultaneous pancreas-kidney transplantation, 10 patients received reoperation because of surgical complications (14 operations). The re-operation rate was 25 %, including 2 patients (4 operations) for hematuria, 4 patients for abdominal hemorrhage, 2 patients (3 operations) for abdominal infection, 1 patient for pancreatic venous thrombosis, 1 patient for anastomotic leakage, and 1 patient for pancreatic fistula. Conclusion Although simultaneous pancreas-kidney transplantation provides a successful and effective treatment for diabetics with endstage renal disease, surgical complication is still affecting the pancreas and kidney grafts after transplantation.
