Objective To study the effect of the genetic factors on the occurrence and development of type 2 diabetes mellitus(T2DM) and its general genetic pattern.Methods 21 T2DM cases,as proband,were investigated for T2DM genealogical tree.The heritability of T2DM was estimated by Falconer method.T2DM segregation rate and genetic pattern were evaluated with Penrose's method,Li-Mantel-Gart method and the threshold value model method of Jiang San-Duo.Results The prevalent rate of T2DM in first-degree relatives was 7.6%,which was higher than that in general population.The heritability of T2DM was 46.8%.The s/q score was 3.312 with Penrose's method,which was near to 1/q1/2.The segregation rate P was 0.131,which was lower than 0.25.The theoretical prevalent rate in first relatives was 8.0%,while the investigated prevalent rate was 7.6%.Conclusion There is an obvious heritable trend in T2DM.It is fit to the multi-factorial inheritance pattern but the mono-gene heritability model.

ObjectiveTo observe the efficacy and safety of patient-controlled intravenous analgesia (PCIA) with morphine and fentanyl after cardiac surgery.MethodsSeventy patients operated with cardiac surgery were randomly divided into morphine group (group M) and fentanyl group (group F). The beginning efficacy time of analgesia,efficacy of analgesia,patient's evaluation,heart rate,respiratory rate,mean arterial pressure,and incidence of nausea and vomiting were assessed.ResultsThere were no significant differences in efficacy and patient's evaluation between two groups. In group G,the beginning efficacy time of analgesia was significantly shorter than those in group M (P<0.05),and the times of nausea and vomiting were significant less than those in group M (P<0.05).ConclusionPCIA with fentanyl and morphine for postoperative pain relief after cardiac surgery is efficient and safe. Compared with morphine,the beginning efficacy time of fentanyl is significant shorter,and times of nausea and vomiting are little.

Objective To construct PPAR?and PPAR?response element (PPRE)-controlled luciferase expression vectors,and to determine whether the traditional Chinese medicine emodin activates PPAR?and improves the glucose uptake by HepG2 hepatocytes.Methods (1) PPAR?and PPRE luciferase expression vectors were constructed and were applied to screen more than 20 ingredients of the traditional Chinese medicine. (2) HepG2 cells were incubated with emodin which can activate PPAR?and PPRE luciferase activity,and the PPAR?mRNA expression level was evaluated by RT-PCR/Southern blot.(3) PPAR?and glucose transporter 2 (Glut2) proteins were determined by Western blot analysis in HepG2 cells treated with emodin.(4) The glucose uptake rate was measured using 2-deoxy-[~3H]-D-glucose in HepG2 cells after treatment with emodin.Results (1) Emodin stimulated luciferase activity controlled by PPRE in dose-dependent manner at concentrations of 0.04 to 180?mol/L in COS-7 cells.The highest value was about 4 folds of control in the cells treated with 90?mol/L emodin (P

OBJECTIVETo investigate the effects of free and pedicled thoracodorsal artery perforator (TDAP) flaps for repairing skin and soft tissue defects in limbs, neck, axillary and shoulder.

METHODSFrom October 2009 to Auguest 2011, 16 TDAP flaps were used to repair skin and tissue defects. Among them, five ipsilateral pedicled flaps were used to repair wounds in neck, axillary and shoulder. 11 free TDAP flaps were used to repair the wounds with bone or tendon exposure. In 12 cases, the flaps were pedicled with thoracodorsal artery and vein-lateral branches-perforators, in 4 cases, pedicled with thoracodorsal artery and vein-serratus anterior muscular branches-perforators. The deep fascia, the latissimus dorsi and thoracodorsal nerve were not included in all flaps. The flaps size ranged from 10 cm x 5 cm to 26 cm x 10 cm.

RESULTSAll 16 flaps survived completely with primary healing both at donor site and recipent area. After a follow-up of 3 to 24 months, all flaps gained good texture and appearance. Only linear scar was left at donor area. The shoulder could move freely.

CONCLUSIONSTDAP flap has good texture, long vascular pedicle,and reliable blood supply, leaving less morbidity at donor site. The latissimus dorsi and thoracodorsal nerve are also preserved. The pedicled TDAP flap is an ideal flap for repairing the ipsilateral skin and soft tissue defects of the neck, shoulder, axillary. The free TDAP flap is suited for repairing skin and soft tissue defects of the extremities.

Background About one third of congenital cataract is associated with inheriting factor.The inherited heterogeneity has been found in congenital cataract.To seek the pathogenic gene is essential for the gene therapy. Objective Present study was to map and identify the causal gene for autosomal dominant congenital cataract (ADCC) in a Chinese family. Methods The clinical features of all affected members in this family were examined.Blood samples were collected from eleven family members for genetic linkage analysis.Polymorphic microsatellite markers were selected from the regions which harbor all known loci linked with ADCC.Universal fluorescent-labeled M13 primer was used in linkage analysis.Direct genomic sequencing was used to evaluate the candidate gene for example CRYBB2 gene.This study followed Helsinki Declaration and was proved by Tianjin City Ethic Committee.Written informed consent was obtained from each SUbject before any medical procees. Results The maximum two-point LOD score of 1.20 was obtained for marker D22S315 (θ=0).The LOD score of 0.6 was obtained for marker D16S3068.No mutation in all exons of CRYBB2 gene was found in the family. Conclusion CRYBB2 gene associated with ADCC was excluded from the family.A genome-wide linkage screening should be conducted.Genotyping with microsatellite markers using Universal fluorescent-labeled M13 primer can decrease the cost and obtain the same result.

Objective To analyse the high-dose dexamethasone suppression test(HDDST)-related differences in the clinical and biochemical features of the patients with Cushing's disease Methods Cases were drawn from 60 consecutive patients with Cushing's disease,who were then divided into two groups according to the response to the HDDST.The clinical and biochemical features between two groups were compared.Results(1) Of the 60 patients with Cushing's disease,23.3%(14/60)of patients(group A)did not yield results of suppression with the HDDST,and the others(group B)did.No difference was found in the age[(33.8?10.4 vs 36.2?11.2)years]and duration of illness[(2.1?1.6 vs 3.9?3.1)years]between two groups.(2)In clinical features,the patients in group A were more likely to have edema of lower limbs(64.3% vs 32.6%),hypokalemia (71.4% vs 28.3%),secondary diabetes(57.1% vs 26.1%)and purple striae(85.7% vs 54.3%,all P

Metabolic abnormalities were identified and carotid intima-media-thickness(IMT)was measured in 221 individuals at risk for metabolic syndrome(MS).The results indicated that IMT was significantly thicker in MS individuals than that in non-MS individuals(P＜0.01).And there was a tendency of progressive increase in IMT with increasing components of metabolic syndrome.
