Qi Yan, Ming Li, Jintao Li
International Journal of Clinical Medicine (IJCM) , 2015, DOI: 10.4236/ijcm.2015.610098
Abstract: Objective: The purpose of this study is to explore the clinical characteristics and therapeutic methods of aggressive fibromatosis (AF) in skull. Methods: The clinical data and operative therapy of one case of aggressive fibromatosis in skull in our department were examined and reviewed. The associated literatures were reviewed and discussed. Results: It was indicated that the main manifestation of AF in skull was headache and skull tumor. There was prominent osteolytic destruction found in X-ray plain film for skull AF. And CT scanning showed that skull sclerotin was disorganized and inhomogeneous, with widen diploe. The skull fibromatosis constituted by fibroblasts and myofibroblas, which were mainly spindle-shaped without heteromorphism. Immunohistochemistry showed positive expression of β-catenin and Vim in these cells. The enlarged incision was adopted for the strategy of operation in this patient of skull AF. After follow-up, there was no recurrence of AF discovered. Conclusions: Skull AF is very rare in neurosurgical clinic. The clinical manifestation and iconography of AF were lack of specificity. Therefore, skull AF is hard to diagnose preoperatively. The effective diagnose is mainly dependant on histopathologic examination. As for treatment, operation is the most optimal method so far, which has a good therapeutic effect.
Effects of interventional therapy with norcantharidin microsphere on hepatoma in rats and its mechanism
Zhong Xi Yi Jie He Xue Bao , 2006,
Abstract: Objective: To investigate the effects of interventional therapy with norcantharidin-alginic acid/poly acid anhydride microspheres (N-MS) infusion via hepatic artery on hepatoma in rats. Methods: N-MS was prepared by emulsion-chemical crosslink technique. Eighty-nine hepatoma-bearing rats were randomly divided into five groups, which were normal saline group, norcantharidin (NCTD) group, blank microsphere (B-MS) group, NCTD-lipiodol group and N-MS group. Normal saline, NCTD, B-MS, NCTD-lipiodol and N-MS were injected via hepatic artery accordingly. After the interventional therapy, eight rats from each group were observed for survival time, and the rest rats were killed on the 8th day after intervention to measure the tumor volume and necrostic degree. The apoptotic index of liver tumor cells was detected by TUNEL staining, and the expression of ki-67 was assayed by immuno-histochemical streptavidin-biotin peroxidase method. Results: The survival time of the rats in the N-MS group was prolonged as compared with those in the other four groups, and the tumor volume of the rats in the N-MS group was smaller than those in the other four groups. The tumor growth rate and the expression level of ki-67 in the N-MS group were both significantly lower than those in the other four groups. The tumor necrotic degree and the apoptotic index in the N-MS group were significantly higher than those in the other four groups. Conclusion: Interventional therapy with N-MS could yield preferable therapeutic effects on hepatomas in rats. This anti-tumor efficacy may be associated with microvessel embolization in liver tumor and the sustained releasing of NCTD. Its inhibiting effect on tumor cell proliferation maybe result from decreasing the expression of Ki-67 and inducing the tumou cell apoptosis
70 years of Bethune Studies in China
Canadian Social Science , 2010,
Abstract: For 70 years, Bethune Studies in China is on the way from propaganda to academic research. Mao Zedong’s In memory of Norman Bethune and Zhou Erfu’s Dr. Bethune have played an important role in propagandizing the image of Bethune. The Scalpel, the Sword by Ted Allan and Sydney Gordon and The Politics of Passion -Norman Bethune's Writing and Art by Larry Hannant are especially the significant works to study Bethune. Since the beginning of 1980s some new features have been presented, such as new information, endless emerging of new works, enlarged number of researchers and the organizational trend of the study and so on. Of cause we have more work to do, which needs the cooperation and the communication between researchers in different areas, between different branches of learning or even between different countries. Key Words: Norman Bethune; Bethune Study; Canada Résumé: Depuis 70 ans en Chine, des études sur Béthune se transforment de la propagande en recherche universitaire. à la mémoire de Norman Béthune de Mao Zedong et Docteur Béthune de Zhou Erfu ont joué un r le important dans la popularisation de l'image de Béthune. Le Scalpel et l'épée de Ted Allan et Sydney Gordon, et Politique de passion - créations et récits de Norman Béthune de Larry Hannant sont notamment des oeuvres importantes pour les études sur Bethune. Depuis le début des années 1980, de nouvelles caractéristiques ont été présentées, tels que de nouvelles informations, de nouvelles uvres émergentes, un nombre accru de chercheurs, la tendance organisationelle de l'étude etc. Nous avons bien s r encore du travail à faire, ce qui nécessite la coopération et la communication entre chercheurs de différents domaines, entre différentes branches de connaissances ou même entre différents pays.

Abstract: Mabuchi introduced multiplier Hermitian structures on compact Kahler manifolds and defined metrics similar to Kahler-Einstein metrics under these structures. In this note we generalize the inequality of Moser-Trudinger type on Kahler-Einstein manifolds to this case.
Distributed Parameter Map-Reduce
Qi Li
Computer Science , 2015,
Abstract: This paper describes how to convert a machine learning problem into a series of map-reduce tasks. We study logistic regression algorithm. In logistic regression algorithm, it is assumed that samples are independent and each sample is assigned a probability. Parameters are obtained by maxmizing the product of all sample probabilities. Rapid expansion of training samples brings challenges to machine learning method. Training samples are so many that they can be only stored in distributed file system and driven by map-reduce style programs. The main step of logistic regression is inference. According to map-reduce spirit, each sample makes inference through a separate map procedure. But the premise of inference is that the map procedure holds parameters for all features in the sample. In this paper, we propose Distributed Parameter Map-Reduce, in which not only samples, but also parameters are distributed in nodes of distributed filesystem. Through a series of map-reduce tasks, we assign each sample parameters for its features, make inference for the sample and update paramters of the model. The above processes are excuted looply until convergence. We test the proposed algorithm in actual hadoop production environment. Experiments show that the acceleration of the algorithm is in linear relationship with the number of cluster nodes.

Dianwei Qi,Li Li
Asian Social Science , 2010, DOI: 10.5539/ass.v7n1p38
Abstract: In 2003, the Central Committee of the Communist Party of China made an importance decision to revitalize old industrial bases in Northeast China. quite a large number of experts and academics have provided specific resolutions to how to revitalize old industrial bases in Northeast China. However, there are still some people who hold the idea of waiting, depending and asking, and they believe that only if the country provides loan, policy and project, can old industrial bases in Northeast China be revitalized. To revitalize old industrial bases in Northeast China is a long term process, so offer of loan, policy and project by the country can only resolve demand for momentary use. The top priority is still to integrate human capital and strengthen vigor of investment in human capital. In view of the above situation, this article points out significance of investment in human capital compared with investment in material capital and mentions that in the process of revitalizing old industrial bases in Northeast China, in addition to offer of loan and project by the country, we should change our mind and make use of our intelligence and wisdom to strengthen vigor of investment in human capital and to revitalize old industrial bases in Northeast China.
A Left-Handed, Stem-Twining Plant from the Miocene Shanwang Formation of Eastern China  [PDF]
Qi Wang, Si Shen, Zhenyu Li
American Journal of Plant Sciences (AJPS) , 2013, DOI: 10.4236/ajps.2013.45A003

Twining stems of plants are very common in extant tropical and subtropical forests, and the climbing growth habit of plants may be an evolutionary innovation and ecological adaptation to either closed, shady or open, edge environments. However, the origin of handedness in climbing plants remains unclear. Here we report a Miocene (ca. 16 million years ago) macrofossil from the Shanwang Formation of Shandong Province, Eastern China, unequivocally exhibiting the first direct fossil evidence for a left-handed, stem-twining growth habit in plants. This fossil plant bears a thicker, slightly curved supporting stem (2 - 3.5 mm wide), which is loosely, spirally twined by a thinner stem (1.5 - 2 mm wide), possibly representing part of distal branches from a liana or vine.

Journal of Cancer Therapy (JCT) , 2013, DOI: 10.4236/jct.2013.46A1007

Objective: To observe the effects and mechanisms of nanocrystallized realgar for the treatment of skin cancer. Methods: The clinical part was observing the therapeutic effect for the skin ulceration by externally using the nanocrystallized realgar. The experimental part was culturing the human squamous cell carcinoma A431 cells (A431) in vitro environment, estimating the effects of proliferation and apoptosis of A431 by MTT method and flow cytometry, and observing the effects on the expression of Survivin, Caspase-3 by RT-PCR method. Results: External treatment with nanocrystallized realgar had a therapeutic effect for the skin ulceration; it can promote the ulcers of skin cancer and skin metastasis healing. The experiments confirmed that nanocrystallized realgar can inhibit the A431 proliferation, induce the cells apoptosis, promote the expression of Caspase-3 and reduce the expression of Survivin. And the experiments also found that the effects were in a concentration-dependent manner, and they have a synergistic effect with cis-Dichlorodiamineplatinum (DDP). Conclusions: External treatment with nanocrystallized realgar for the patients of skin cancer or skin metastasis achieved satisfactory therapeutic effects by inhibiting A431 proliferation and inducing these cells apoptosis. The mechanism might be associated with promoting the expression of Caspase-3 and reducing the expression of Survivin.

Open Journal of Social Sciences (JSS) , 2019, DOI: 10.4236/jss.2019.73040
In the process of transition from general foreign language teaching to military foreign language teaching, the main challenge facing the foreign language teaching reform in military academies is how to define and test the new foreign language teaching objectives scientifically. The paper points out that it is the key to solve the dilemma of foreign language teaching in military academies to grasp the special requirements of the application of military foreign language ability and integrate it systematically into the whole process of talent training. This study can provide a reference for the reform of foreign language teaching in military academies and provide some enlightenment for the reform of foreign language teaching reform in local colleges and universities.
