Objective To study the significance of radiotherapy of mediastinal metastasis after radical surgery for thoracic esophageal carcinoma. Methods Seventy six patients with esophageal carcinoma who developed mediastinal metastasis 3～18 months after radical surgery were retrospectively analyzed. The size of mediastinal metastasis was 3?cm in 32. Nine of these patients had metastasis in neck lymph nodes and 3 had distant metastasis as well. Radiotherapy was given with a Cobalt 60 unit. The radiation dose ranged from 10.8?Gy to 75.0?Gy by conventional fractionation. Results Nine patients did not finish radiotherapy and all of them died within one year of (after) treatment. The mean of survival time was 4.9 months. Sixty seven patients received radiation of 50～70?Gy. The corresponding overall survivals at 1, 2, and 3 years were 75.0% (57/76), 27.6% (21/76) and 9.2% (7/76), respectively. Conclusion Radical radiotherapy may improve the prognosis with an appropriate tumor dose of 65～75?Gy.

Cancer metastasis is multi-step process that requires cancer cells to jump through many hoops.The low-molecule-weight beparin (LMWH) has been reported effective for the treatment of metastasis to some extent, the mechanisms are proposed as anticoagulation, inhibition of heparanase, selectins, adhesion, angiogenesis mediated by the tumor cells, and the effects on cell cycle and apoptosis.

Objective Industrialized breeding technology system will be established to achieve the rapid multiplication of Pinellia ternata and to settle the problem of degeneration caused by seeds. MethodsExplant induction and effects of plant growth regulator dosage, illumination, and subculture cycle on fasciculated shoot propagation were studied. ResultsIt is good for the explant induction on medium MS+6-BA (4-5) mg/L+NAA 0.2 mg/L. P.ternata grows well under the circumstance of NAA 0.2 mg/L+6-BA 2 mg/L, double or more shoots. ConclusionIndustrialized breeding technology system of P.ternata can make its propagation rapid and support an effective way for resources preserving and sustainable utilization.

The normative research on safeguarding intangible cultural heritage of traditional Chinese medicine is the important measure after building list and filing work of Convention of the protection of intangible cultural heritage of UNESCO, and also a strategy in accordance with the principle of the protection of traditional knowledge of traditional Chinese medicine.This article discussed the arrangement and standardization in the academic level of folk medicine technology teaching orally from generation to generation, to provide protection for the living inheritance of intangible cultural heritage of traditional Chinese medicine, and a pilot measure for the construction of intangible cultural heritage protection system.

AIM: To investigate the role of ubiquitin-proteasome system ( UPS) in adipocyte differentiation. METHODS:Differentiation of 3T3-L1 preadipocytes into adipocytes was induced by treatment with insulin, 3-isobutyl-1-methylxanthine and dexamethasone.Western blot and immunoprecipitation were performed to detect the protein abundances and association, respectively.Oil red O staining was used to determine the intracellular lipid of 3T3-L1 adipocytes.The levels of mRNA were measured by reverse transcription polymerase chain reaction ( RT-PCR) .RESULTS:UPS inhibitor bortezomib (BZM) suppressed the differentiation of 3T3-L1 pre-adipocytes, evidenced by reduced intracellular content of triglyceride, and decreased mRNA expression of adipogenic marker proteins such as adiponectin and adipocyte protein 2.In contrast, administration of sildenafil (SDN), an activator of protein kinase G which was also found to activate UPS, promo-ted adipocyte differentiation.In addition, BZM treatment decreased the expression of heat shock protein 90 (HSP90) and peroxisome proliferator-activated receptor gamma ( PPARγ) in the soluble fraction and reduced association of HSP90 and PPARγ.Furthermore, HSP90-specific N-terminal inhibitor geldanamic mitigated SDN-induced increase in PPARγlevel and 3T3-L1 cell differentiation.CONCLUSION:UPS modulates HSP90-dependent PPARγstability, thus leading to pro-motion of adipocyte differentiation.

Objective To survey the current living situation, protection condition, suggestions and demands of protective items and inheritors of TCM intangible cultural heritage;To analyze existing problems and solutions of protection;To lay the foundation for further protection. Methods Survey was carried out through table investigation and meeting and convention from the aspects of item overview, situation of inheriting community, protection status, and demands and suggestions. Results TCM intangible cultural heritage is inherited through traditional teaching and learning between masters and apprentices, and family inheriting. Some inheriting communities are too small, and some inheritors are too old, which make the inheriting prospect quite gloomy. Protective levels of items of TCM intangible cultural heritage vary. Most items are protected by protective institutions, protective personnel, and learning-teaching sites. Some items are supported by protective fund;archive data about the items are filing;researches and work about propaganda and education are also carried out. Conclusion Protection of TCM intangible cultural heritage has made certain achievements. However, some problems about funds, inheriting, filing, training, and propagandizing should be solved.

Through the investigation on Dendrobium Sw. resources of Chongqing, the species, distribution, ecological environment, and industry situations were basically clarified. The results showed that six counties including the Nanchuan district and Shizhu county had about 4 species, which mainly grew on trunks of forest plants such as Quercus phillyreoides, Ficus virens, walnut tree, and Fagus longipetiolata, as well as cliff valley. Its growth of the main conditions and illuminations has a great influence on ecological factors in Dendrobium Sw. stem growth. The cultivated variety of Dendrobium Sw. was a single. It was still in the early-stage trial of industry development.

Objective To summarize the clinicopathologic characters and the route of lymphatic metastasis of cancers at the gastroesophageal junction. Methods Clinicopathologic data of 86 cancer patients treated from October 2000 to December 2004 were analyzed retrospectively. Results There were 66 males and 20 females, the mean age was 60 years. Most patients were of Bormann typeⅢadenocarcinoma. The incidence of high differentiated adenocarcinoma in TypeⅠcancer was higher than that in other two types (P = 0. 002, P = 0. 004) , while the incidence of poor differentiated carcinoma in typeⅢcancer was higher than other two types(P = 0. 005 ,P = 0. 015). Metastatic rate of lymph nodes in group 1 and group 2(34. 9% ) .group 3 and group 4(36. 0% ), group 7 through to group 9(27. 9% ), group 10 and 11 (15. 1% ) was higher than in other groups, while that in group 5 and 6(11. 6% ) , and group 12(5. 8% ) was lower compared with other lymph nodes (P
