This paper presents one case of total glossectomy and six cases of subtotal and partial glossectomy with transplantation of free forearm flaps to repair and reconstruct tongue defects.In this series, the operation proved successful in six cases, but failed in one only.The operation achieved the desired contour and function of the tongue,The authors have accordingly attempted a new procedure of glossal reconstruction. Prospects concerning improvement of the technique are discussed.

An experimental study of vascularized and nonvascularized free bone-grafts for mandibular defects in dogs was conducted.The different bone healing process was observed by histological study.The results show that with 3 cm-length bone graft either vascularized or nonvascularized its healing process is similar.Both bones of donor and receptor have osteogenic activity.This process is similar to that of fracture healing.

Objective: To quantitatively analyze the content of glucose in glucose injection by near infrared spectroscopy to control the quality of the product.Methods: A quantitative model was established by near infrared reflectance spectroscopy and the injection came from pharmaceutical enterprises with different concentrations of glucose and the solution samples came from laboratories with different concentrations of glucose.The liquid sample accessories were selected, a quantitative model was established by a partial least squares method, and the effect of environmental temperature on the model was studied as well.Results: According to the quantitative model, the correlation coefficient reached up to 0.999 3, and RMS deviation (RMSECV) was 0.077 4.In the verification test, the results of various liquid formulas containing glucose were similar to those of the laboratory results.The prediction error was less than 5% within the temperature range of 20-35℃.Conclusion: The model of near-infrared partial least squares (PLS) can accurately predict the content of glucose in glucose products without sodium chloride, and can be used for the quality control of glucose intermediates and the finished products in the large infusion manufacturers

The tongue and its surrounding structures have special anatomical and functional characters and how to restore its shape and function after glossectomy (especially total glossectomy) still remains a difficult problem. The authors devised a new method of repair by using a forearm free flap with results in 16 out of 17 patients. The selection and shaping of the flap, the evaluation of the recipient site and its blood vessels, the prevention of the oral infection,the monitoring of the circulatory status of the flap and the evalution of the operative result were discussed.

Objective: To summarize the experience of repairing or al and maxillofacial defects with radial forearm free flap. Methods: The clinical records of 110 cases received oral and maxillofacial reconstruction with radial forearm free flap were analyzed.Results: Forearm free flap healed well in 10 5 out of the 110 cases.with the overall success rate of 96.4%.Failure was in 4 c ases of cancer.One patient died from cerebral infarction 19 days after operation .Post operation infection did not result in the necrosis of the flaps because o f corresponding treatment in 5 cases.Conclusion: The radia l forearm free flap characterized by the anatomical consistency,easy fold, ideal thickness, flexibility and long pedicle, is feasible in the reconstruction of soft tissue defects in oral and maxillofacial region.

Objective To discriminate Rhizoma Pinelliae from its relative species by electrophoro-gram of protein.Methods Using isoelectrofocusing(IEF) technology to compare the electrophorogram of tuber of Pinellia ternata produced in different habitats and from its relative plants then determining the pH values.Results The IEF electrophorogram of Rhizoma Pinelliae was stable with eight clear characteristic protein bands and had obvious differences from the electrophorogram of the tubers of its relative plants.Conclusion The IEF electrophoresis of Rhizoma Pinelliae can be used as the distinguishing basis.The PI value of the characteristic protein of P.ternana offers the basic parameter for separation and purification of the protein in Rhizoma Pinelliae.

Objective To explore the role of integrin in CCL18 for promoting breast cancer SK-3 rd cells invasion and migration process to illuminate the molecular mechanism of CCL 18 for promoting breast cancer SK-3 rd cells invasion and migration process . Methods The flow cytometry was adopted to detect CCL18-induced integrin aggregation ;Western blot was used to detect the focal adhesion kinase(FAK ) activation ,the infiltrating migrationin experiment was adopted to determine the invasion and migration of SK-3rd cells and the siRNAs transfection was used to detect the expression of silence integrin β1 .Results CCL18 promoted the in-tegrinβ1 aggregation in breast cancer SK-3rd cell surface and further promoted the integrin-mediated phosphorylated activation of FAK .Under the reaction of CCL18 ,the cells number of SK-3rd cellular invasion and migration was increased by ten times (P<0 .01) ,which was obviously decreased by siRNA silenced integrin β1 .Conclusion CCL18 promotes breast cancer invasion and mi-gration via integrin aggregation .

To establish seven kinds of minerals containing sulfate kind of near infrared spectral identification method
of traditional Chinese medicine (TCM). 7 species of mineral medicine containing sulfate after crushing sieving, measure all the samples in 12 000-4 000 cm-1 section within the scope of the near infrared spectrum, spectrum signal by different pretreatment methods, after the screening of the different characteristics of the spectrum to extract the effective information, using cluster analysis method for qualitative identification. In 8 600-8 100 cm-1, 5 843-4 245 cm-1, 7 096-6 337 cm -1 section within the scope of the atlas signal after the vector normalization and multiple scattering correction, K-average clustering analysis to 20 batches sulfate kind of mineral medicine is divided into seven categories, the results of the analysis method and the traditional traits identification results are basically identical. This method is simple, fast, and can be used for these minerals containing sulfate class the qualitative identification and quality control of Chinese traditional medicine.

This study was aimed to establish X-ray diffraction (XRD) Fourier fingerprint of mineral Chinese medicine Actinolitum, in order to provide a new method for evaluating the quality of Actinolitum. Actinolitum samples were analyzed by the technology of powder XRD. And the XRD Fourier fingerprint was determined. Accord to the fingerprints and the intensity of each characteristic peak in XRD patterns of Actinolitum, the similarity of different samples were calculated using the law of cosines and the correlation coefficient method. Systematic cluster analysis was also used for the data. The results showed that XRD patterns of 10 certified products, 3 doping products and 2 counterfeits of Actinolitum were obtained. The geometric and topological characteristics of 10 certified products were consistent. XRD fingerprint of Actinolitum from 10 certified products had 18 common characteristic peaks. The similarity analysis showed that the similarity of XRD patterns common peak of certified products were higher among 15 samples (> 0.98). The similarity of doping products was slightly lower (0.85-0.97). And the counterfeits had the lowest similarity (< 0.2). These three had significant differences which can be distinguished. The results of cluster analysis were consistent with the similarity analysis results. It was concluded that XRD fingerprint had good specificity and feasible. It was accurate and reliable, which can be used to distinguish and evaluate Actinolitum.

Conclusion:The above mentioned results exhibit that Desmodium styraeifolium from Guangdong,Guangxi and some wild herbal populations has high genetic diversity. The clustering results illustrate that the genetic distance of Desmodium styraeifolium originated from Guangdong and Guangxi is related with geographic distance.
