Total RNA was extracted from leaf of Suaeda hetroptera kitag, then the CMO ( choline monooxygenase) cDNA was amplified using the reverse transcriptase polymerase chain reaction ( RT-PCR) method and cloned into pMD-T-simple vector. The positive clones from the Blue/White Screen were sequenced. After confirming its validity, the CMO gene fragment was cloned into pBI121 vector. Double enzyme restriction and PCR analysis indicated that the pBI121/CMO recombinant plasmid was successfully constructed.

This paper focuses on the trends in wearable medical devices for the applications in m-health. The state-of-art technologies for the continuous and noninvasive measurements of physiological parameters, implementation platforms of wearable medical devices - e-textile, and body sensor networks are reviewed here with examples of related recent research projects conducted in different countries. In addition, we introduce our recent research project on the e-textile-based health shirt (h-shirt), which can measure arterial blood pressure noninvasively, continuously and cufflessly.

OBJECTIVETo explore a new technique that keep function and good aesthetic shape after reduction mammaplasty.

METHODSThe superomedial glandular pedicle technique was applied with differing patterns of skin incision according to the degree of the mammary hypertrophy. The extra glandular tissue was removed from the lateral and inferior segment of the breast. The remaining superomedial glandular tissue was remodeled a conical shape. The skin incision was sutured after excision of excess skin.

RESULTS36 cases (72 breasts) were treated with this technique. The results were satisfactory and there were no complications. The breasts maintained a lasting and aesthetically pleasing shape and the nipple-areola preserved good sensation.

CONCLUSIONSThe superomedial glandular pedicle is a safe and effective technique that can provide long-lasting outcome. The design of the procedure can be adapted to a variety of skin incision patterns and breast morphologies.

Postnatal mesenchymal stem cells have the capacity to differentiate into multiple cell lineages. This study explored the possibility of dental pulp stem cells (DPSCs) for potential application in tendon tissue engineering. The expression of tendon-related markers such as scleraxis, tenascin-C, tenomodulin, eye absent homologue 2, collagens I and VI was detected in dental pulp tissue. Interestingly, under mechanical stimulation, these tendon-related markers were significantly enhanced when DPSCs were seeded in aligned polyglycolic acid (PGA) fibre scaffolds. Furthermore, mature tendon-like tissue was formed after transplantation of DPSC-PGA constructs under mechanical loading conditions in a mouse model. This study demonstrates that DPSCs could be a potential stem cell source for tissue engineering of tendon-like tissue.

Objective To analyze the epidemic tendency of Microtus fascus plague during 2000-2008 in Sichuan province. Methods To investigate the plague each year according to "overall Plan of the Plague in the Whole Nation" and "Surveillance Program of Sichuan Province Plague". Results There were plague epidemic from 2000 to 2008, with the average density as 312.41/ha. 42.57% of the Microtus fuscus were infected by body Fleas. The Fleas Index was 0.88 and the Index for nest Fleas of Microtas fuscus was 55.89. Six kinds of animals were infected by not only the Microtus fuscus but also herd-dog, sand fox, Tibetan sheep, domestic cats and Cricetulus longicaulatus as well. The positive rate of live Microtus fuscus was 0.32% but 22.99% in the dead Microtus fuscus. The overall positive rate on serological test was 6.70%. There were 4 Sections, 11 species and 19 kinds Fleas identified and carrying 3 kinds of fleas, Callopsylla sparsilis, Amphipsylla tntua tutua and Rhadinopsylla dahurica vicina, with the overall infection rate as 0.054%. Conclusion Plague among Microtus fuscus showed a continuous epidemic in Sichuan province during 2000-2008.

Objective To analyzed the variant information on the indices regarding fleas from natural foci of Microtus plague in Sichuan epidemic area during 2000 to 2008.Methods Statistical and analytical methods were used on the surveillance data regarding Microtus fuscus plague.Results There were 19 flea species identified and the share of Callopsylla sparsilis was 62.79 percent while the share of Amphipsylla tuta tuta was 30.90 percent on Microtus fuscus plague.The infection rate of fleas and the flea index were the highest in October and the lowest in December and March.Species as Callopsylla sparsilis,Amphipsylla tuta tuta and Rhadinopsylla dahurica vicina could naturally infect the Yersinia pestis.Conclusion Microtus fuscus plague could become epidemic when animals and flea species were infected.We should emphasis on plague monitoring program so as to prevent the occurrence of the disease.

OBJECTIVETo determine the relationship between velocimetric parameters by using color Doppler ultrasonography and microvessel density (MVD) in papillary thyroid carcinoma and its clinical significance for preoperative diagnosis of papillary thyroid carcinoma. Methods Twenty-nine thyroid tumors were examined preoperatively by color Doppler ultrasonography. The velocimetric parameters including peak systolic velocity (V(max)), end-diastolic velocity (V(min)) were evaluated respectively and resistance index (RI) was calculated. Immunohistochemistry was applied by using polyclonal rabbit anti-human Von Willebrand factor in all cases after operation and microvessel density was calculated based on it.

RESULTSOf the twenty-nine patients who underwent surgery, seventeen patients were diagnosed in papillary thyroid carcinoma and twelve patients in thyroid adenoma. In velocimetric analysis, the RI was significantly higher in patients with papillary thyroid carcinoma than those with thyroid adenoma (t = 3.3108, P < 0.01). V(max) and Vmin were no significance in those two tumors respectively (Z = 0.9520, P > 0.05; Z = - 1.6618, P > 0.05). MVD was also significantly increased in patients with papillary thyroid carcinoma (t = 8.1991, P < 0.01). There was a significant positive association between RI and MVD (r = 0.7924, P < 0.01).

CONCLUSIONSColor Doppler ultrasonography could well display the blood flow of thyroid tissue and its nodules. The velocimetric parameter RI was higher in papillary thyroid carcinoma than in adenoma and was along with its MVD. RI may provide valuable information for diagnosis of papillary thyroid carcinoma preoperatively.

OBJECTIVETo investigate the correlation of single nucleotide polymorphisms (SNP) of XRCC1 gene to hereditary susceptibility of colorectal cancer.

METHODSXRCC1 genotypes in 124 colorectal cancer patients and 214 matched healthy people as control were analyzed by SnaP Shot SNP-typing technique. Five different inheritance models including codominant, dominant, recessive, overdominant and log-additive were analyzed using logistic regression model. The haplotype distribution was estimated with phase and its correlation with the risk of colorectal cancer was evaluated.

RESULTSThe frequencies of mutant 25487G-A, 25489C-T and 1799782C-T alleles were 0.20, 0.11, 0.32 respectively in the patients, and 0.23, 0.13, 0.34 in the controls. There was no significant correlation of polymophisms of XRCC1 gene to the risk of colorectal cancer in 5 different inheritance models (P>0.05). GCT, GCC, ACC and GTC were the most common haplotypes and the odds ratios were 1, 1.35, 0.90 and 0.84 respectively. There was no significant difference of distribution between 2 groups in haplotypes.

CONCLUSIONPolymorphisms of XRCC1 gene, including rs25487, rs25489, rs1799782, are not associated with to the risk of colorectal cancer.
