Objective To evaluate the diagnostic value of ~(99)Tc~m-methoxyisobutylisonitrile (MIBI) SPECT scintigraphy combined Iocalizable CT in the localization of ectopic parathyroid glands in hyperparathyroidism.Methods Retrospective data of surgery,pathology and imaging were collected from 28 patients with hyperfunctioning ectopic parathyroid glands.All cases underwent CT studies.Twenty-five patients had ~(99)Tc~m-MIBI planar imaging first:SPECT scintigraphy combined localizable CT was performed for the patients with abnormal radionuclide foci immediately.The fusion images obtained after reconstruction showed the exact location of the ectopic foci.Operative histopathologic results were regarded as "gold standards".Presuming 4 parathyroid glands as normal findings,findings confirmed by operation and pathology were regarded as positive,otherwise negative.The results of CT and radionuclide imaging were compared by X~2-test of four-foId table.Results Twenty-eight ectopic parathyroid glands were found in 28 patients,all pathologically confirmed as adenomss.CT found 22 foci,of which 17 were true positive,5 false positive,11 false negative,and 79 true negative.~(99)Tc~m-MIBI SPECT scintigraphy combined localizable CT found 23 foci,no false positive,2 false negative,and 75 true negative.The results showed that the sensitivities were 61% (17/28),92%(23/25),specificities 94%(79/84),100%(75/75),accuracies 86%(96/112),98% (98/100),positive predictive values 77%(17/22),100%(23/23),and negative predictive values 88% (79190),97%(75/77),respectively,for CT and radionuclide imaging.~(99)Tc~m-MIBI SPECT scintigraphy combined localizable CT was therefore significantly higher than CT in sensitivity(X~2=6.98,P＜0.01),specificity (X~2=4.61,P＜0.05),accuracy (X~2=10.30,P＜0.01),positive predictive value(X~2=5.88,P＜0.05) and negative predictive value (X~2=5.36,P＜0.05).Conclusion ~(99)Tc~m-MIBI SPECT scintigraphy combined localizable CT is superior to CT alone in the localization of ectopic parathyroid glands in hyperparathyroidism,but false negative can be found in some patients.

In silkworm moth the colleterial gland markedly enlarged due to the secretion and accumulation of glue like substances before adult emergence. However, the Ng mutant female moth only secreted little glue-like substance and laid loose eggs naturally. In the present experiment, it was extracted the proteins of secretory part of the variety E981 and its Ng mutant line and analyzed by two-dimensional electrophoresis. More than 700 protein spots were resolved both in two samples and most of the proteins were distributed in the area from 30 kD to 70 kD and pH 4 - 8. Through the comparison and analysis, it was found that 4 proteins were only expressed in E981 and 2 proteins were only expressed in Ng mutant. Furthermore, there are about 29 proteins were expressed higher in 981 and about 15 proteins expressed volume were higher in Ng mutant. These differential proteins may be have some relations with the Ng mutant form and directly lead to the Ng mutant can't secret the glue-like substance.

T site polymorphism is closely related to CHD and elevated serum triglyceride and total cholesterol.

In order to characterize the molecular epidemiology of HFMD-associated Coxsackievirus A6 (CVA6) in Fujian Province, a total of 1340 specimens from non-EV71 non-CVA16 HFMD patients were collected during 2011-2013. Isolated virus strains were identified and subtyped. Full-length coding regions for the VP1 gene of the predominant serotype CVA6 isolates were amplified and sequenced. Among the 375 non-EV71 non-CVA16 HFMD cases confirmed by virus isolation and molecular subtyping, 182 (48.5%) were found to be caused by CVA6, accounting for 7.9%, 16.2% and 39.6% HFMD-associated enteroviruses in FujianProvince during 2011, 2012, and 2013, respectively. Compared with general features observed in the HFMD epidemic, no difference in CVA6-specificity or severity rates was observed between geographical origins, gender, or age groups. Nucleotide sequence analyses of VP1 genes revealed high diversity levels of 16.2%-18.6% among CVA6 strains from Fujian Province, in contrast to the prototype CVA6 strain, and showed low levels of diversity in the amino acid sequences (4.3%-6.2%). Phylogenetic analysis also indicated that CVA6 isolates from Fujian Province were distinct from the prototype strain and other isolates from abroad; however, it was homologous to domestic strains, although the Fujian isolates clustered into multiple branches. These results suggested that significant changes in the pathogenic spectrum of HFMD in Fujian Province occurred during 2011-2013, as CVA6 was one of the predominant serotypes of HFMD. CVA6 isolates from Fujian Province were co-circulating and co-evolving with other domestic strains as multiple closely related CVA6 transmission chains were observed in Fujian Province overall and within each prefecture.

OBJECTIVETo investigate the relationship between SNPs reported in previous studies and the blood lipid level in the Tibetan population.

METHODSRandom cluster sampling was employed in 5 areas (Lhasa, Shigatse, Shannan, Nagqu, and Nyingchi). The levels of cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL-C) from blood samples were determined and DNA was extracted for genotyping and statistical analyses.

RESULTSAmong 1 318 subjects aged >18 years enrolled in this study, 367 had dyslipidemia with a prevalence of 27.8%, of whom dyslipidemia males accounted for 33.1% and dyslipidemia females -24.5%. Results of the correlation analysis between all SNPs and TG showed that the SNPs of rs714052 and rs964184 were related to the serum TG level. Subjects with rs714052 CC genotype had the lowest TG level, and the highest TG level was found in those with rs714052 TT genotype. The serum TG level in individuals with TC genotype lied in between the above two population groups. Subjects with rs964184 CC genotype had the lowest TG level, and the highest serum TG level was noted in those with rs964184 GG genotype.

CONCLUSIONSeveral SNPs were found to be related to the serum TG level in the Tibetan population. The APOA5 gene and MLXIPL gene may be closely associated with the serum TG level in this ethnic population group.

OBJECTIVETo introduce the clinical experience in transplantation of the anterolateral femoral skin flap.

METHODSA total of 625 anterolateral femoral skin flaps in 600 patients were transplanted from 1988 to 2003. The retrospective analysis was carried out in all the cases as to the flap pedicle, the vascular variations, the surgical procedures and modifications, and the adaptation for a cutaneous-branch-absent flap.

RESULTSThe 625 flaps were transferred except 7 cancelled in the operation. Postoperatively, 17 cases encountered vascular complications, 10 of which survived completely with successful vessel exploration, 3 cases had partial necrosis, and 4 cases had complete necrosis. The survival rate was 97.8%. 545 flaps were pedicled with the descending branch or lateral branches; 45 flaps with the transverse branch or the high-site anterolateral cutaneous artery, 10 cases with the descending-transverse branch, 18 cases with other vessels. 7 cases were found cutaneous-branch-absent. The vessel variation rate of the flap was 4.06%.

CONCLUSIONSThe anterolateral femoral skin flap has less variation of its pedicle and high success rate of operation. It is an ideal choice for repair of soft tissue defects in the extremities.

OBJECTIVETo investigate the effects of San Baoxin on myocardial injury induced by ischemia-reperfusion (MI/R) and thrombogenesis in rats in vivo and ex vivo.

METHODThe experimental model was established by ligation of left anterior descending coronary artery for 30 min followed by reperfusion for 180 min. The Chandler method was used to produced ex vivo thrombosis and an electrical stimulation of common carotid artery was adopted to form in vivo thrombosis respectively, the effect of antithrombosis induced by San Baoxin was observed.

RESULTSan Baoxin significantly decreased the content of malondialdehyde (MDA), obviously elevated the activity of superoxide dismutase (SOD) and increased the amount of NO of the serum simultaneously. The San Baoxin at the dosage of 10 g x kg(-1) could remarkably lengthen the OT ( P < 0.05). All San Baoxin dosages could inhibit the formation of ex vivo thrombosis.

CONCLUSIONSan Baoxin protects the myocardium from injury of ischemic and reperfusion. The protective effect of San Baoxin may be due to that it can dilate vessels, increase the activity of clearance enzyme of free radical and inhibit lipid peroxidation and the formation of ex vivo and in vivo thrombosis.
