  • Background: The research was to compare the efficacy and side effects of cisplatin or lobaplatin in combination with mitomycine (MMC) and vincristine in treating patients with cervical squamous carcinoma. Materials and Methods: Cervical squamous carcinoma patients who were pathologically diagnosed with stage Ib-IIb from April 2012 to May 2013 in the general hospital of Chinese People's Libration Amy were enrolled. All patients were confirmed without prior treatment and were randomly divided into two groups, Group A and B. Efficacy and side effects were evaluated after one cycle of chemotherapy. Results: Group A (n=42) were treated with Loubo$^{(R)}$ (Lobaplatin) $50mg/m^2$, MMC $16mg/m^2$ and Vincristine $2mg/m^2$ every 21 days. Group B (n=44) were treated with Cisplatin $100mg/m^2$, MMC $16mg/m^2$ and Vincristine $2mg/m^2$ every 21 days. All 86 patients completed one cycle of chemotherapy with cisplatin or lobaplatin in combination with MMC and vincristine. No difference was observed regardiing short-term effect between two groups. Main side effects were bone marrow suppression and gastrointestinal reactions including decrease of white blood cells, platelet and nausea/vomiting. Grade III-VI liver and kidney impairment was not reported in two groups. In group A the incidence of uterine artery spasm in the process of drug delivery was significantly lower than the group B. Conclusions: Cisplatin or lobaplatin with MMC and Vincristine in the interventional treatment of cervical squamous carcinoma were effective, especially after uterine artery perfusion chemotherapy at tumor reduction and tumor downstaging period. The adverse reactions of concurrent chemotherapy are tolerable, and low physical and mental pressure even more less stimulation of vascular in treatment with lobaplatin. However, the long-term effects of this treatment need further observation.

  • Background: TIAM2, a Rac guanine nucleotide exchange factor, is closely associated with cell adherence and migration. Here, we aimed to investigate the role of TIAM2 in non-small cell lung cancer (NSCLC) cells. Materials and Methods: A small interference RNA (siRNA) was introduced to silence the expression of TIAM2. Invasion and motility assays were then performed to assess the invasion and motility potential of NSCLC cells. GST-pull down assays were used to detect activation of Rac1. Results: TIAM2 was highly expressed in NSCLC cells. Knockdown of TIAM2 inhibited the invasion and motility, and suppressed activation of Rac1. Further experiments demonstrated that knockdown of TIAM2 could up-regulate the expression of E-cadherin, and down-regulate the expression of MMP-3, Twist and Snail. Conclusions: Our data suggest that TIAM2 can promote invasion and motility of NSCLC cells. Activation of Rac1 and regulation of some EMT/invasion-related genes may be involved in the underlying processes.

  • Chinese medicine is a precious treasure inherited from ancient ancestors. It is accredited for the prosperous growth of the Chinese nations. However, the descriptions of the herbs in the ancient herbal are not in detail and the great numbers of herbs used which grows in wide geographic areas together with various local folk names, new substitutes and new folk medicines had increased, many Chinese herbs are composed of herbs that are labeled with identical names but actually are of different origins and different grades. Similar situation had occurred in China, japan and Korea In Taiwan, misused Chinese crude drugs are also very common in the past. This phenomenon had caused a lot of confusion and had great influence the clinical efficacy of the treatment. In the past, Professor Hong Yen Hsu, Na Chi, Woei Song Kan and Kung Yin Yen had studied the origins of Chinese crude drugs in Taiwan based on the morphological identification and found that the origins of Ma-Tou-Ling, Pu-Kung-Yin, Tu-Chung, Wang-Pu-Liu-Hsing, Pan-lan-Ken, Niu-Chi, Fang-Chi, Huang-Chi, PienHsiu and Sha Wan-Tzi are different from that of the species used in mainland China. In order to assure the quality and clinical efficacy of the crude drugs, besides the traditional morphological methods, we bad recently combined modem chemical and pharma-cological methods to assess drug quality. Drugs that have been evaluated without effects should be abandoned. The species of those commonly misued crude drugs used in compound formula preparations are also identified Based on the pharmacological results, a suitable species is recommended so as to improve the clinical efficacy of those preparations. In this paper, we like to report our recent studies on Niu Chi(Achyranthis Bidentatae Radix, Cyathulae Radix and Strobilanthis Radix). Fang-Chi(Arstolochiae Fangchi Radix, Stephaniae Tetrandrae Radix and Cocculus Radix) and Huang-Chi(Astragali Radix and Hedysari Radix) using comparative pharmacognosy methods.

  • The complete coding region sequence of the SRY gene in Chinese swamp buffalo was determined by PCR product sequencing. Comparison of swamp and river buffalo SRY gene sequences revealed a single nucleotide polymorphism (SNP, C/G) at the 202 bp site of the coding region. Further, a total of 124 male domestic buffaloes were genotyped at this SNP site using the PCR-SSCP method, and it was found that all Chinese indigenous swamp buffaloes had a guanine (G) at this site, while introduced river buffaloes and crossbred buffaloes showed a cytosine (C). Our findings suggested that this Y-linked SNP displayed type-specific alleles differentiating swamp and river buffaloes, and could be used as an effective marker to detect crossbreeding of swamp buffaloes with introduced river buffaloes in native buffalo populations, and thereby assess genetic diversity status and make proper conservation decisions for indigenous swamp buffaloes. In addition, this SNP can be potentially applied in the study of Asian water buffalo phylogeny from a male perspective.

  • The number of hidden neurons of the feed-forward neural networks is generally decided on the basis of experience. The method usually results in the lack or redundancy of hidden neurons, and causes the shortage of capacity for storing information of learning overmuch. This research proposes a new method for optimizing the number of hidden neurons bases on information entropy, Firstly, an initial neural network with enough hidden neurons should be trained by a set of training samples. Second, the activation values of hidden neurons should be calculated by inputting the training samples that can be identified correctly by the trained neural network. Third, all kinds of partitions should be tried and its information gain should be calculated, and then a decision-tree correctly dividing the whole sample space can be constructed. Finally, the important and related hidden neurons that are included in the tree can be found by searching the whole tree, and other redundant hidden neurons can be deleted. Thus, the number of hidden neurons can be decided. In the case of building a neural network with the best number of hidden units for tea quality evaluation, the proposed method is applied. And the result shows that the method is effective

  • Female germ cell meiotic divisions are typically asymmetric, giving rise to two daughter cells with different sizes. Spindle movements including spindle migration from the oocyte center to the cortex and spindle rotation from parallel to perpendicular (typically in the mouse) at the cortex are crucial for these asymmetric divisions and therefore are crucial for gamete production. Different regulatory mechanisms for spindle movements have been determined in different species and a wide variety of different molecular components and processes that are involved in spindle movements have also been identified in different species. Here, we review the current state of knowledge as well as our understanding of mechanisms for spindle movements in different systems with focus on three main aspects: microtubules (MT), microfilaments (MF) and molecules associated with cytoskeletal organization as well as molecules that are not directly related to the cytoskeleton. How they might interact or function independently during female meiotic divisions in different species is discussed in detail.

  • In order to explore the association between RASSF1A methylation and nasopharyngeal carcinoma (NPC) risk of Chinese, we carried out a meta-analysis with searches of PubMed, Web of Science, ProQest and Medline databases. Ultimately, 14 articles were identified and analysised using R Software (R version 3.1.2) including meta packages. Overall, we found a significant relationship between RASSF1A methylation and NPC risk (OR 30.7; 95 % CI, 16.71~56.23; z=11.0591; p<0.0001) in a fixed effects model and (OR 32.1; 95% CI, 14.27~72.01; z=8.3984; p<0.0001) in a random effects model pooled. In tissue and NP brushings groups, similar results were found. Hence, our study identified a strong association between RASSF1A methylation and NPC and highlighted a promising potential for RASSF1A methylation in NPC risk prediction of Chinese.

  • A new kind of silicone-epoxy composite is reported in this research. The silicone-epoxy resin was synthesized by the hydrosilylation of tetramethycyclotetrasiloxane and 4-vinyl-1-cyclohexene 1,2-epoxy with a high reaction yield. It was found that the obtained silicone-epoxy resin shows a high reactive activity to the aluminum complex-silanol catalyst. The resin could be cured under the catalysis of $(Al(acac)_3/Ph_2Si(OH)_2$ at a concentration below 0.1 wt% to give a hard cured resin showing excellent optical clarity, UV resistance and thermal stability. It was also found that the Si-H groups facilitated the curing reaction and the silicone-epoxy resin bearing Si-H group could be cured effectively even if $Ph_2Si(OH)_2h$ was absent. Moreover, the UV resistance and thermal stability were improved significantly by the introduction of Si-H groups. This is possibly due to the reductive property of Si-H groups which can annihilate radical and peroxide effectively. This kind of silicone-containing epoxy composite might have very promising applications as optical resin, optical adhesive and encapsulation materials for electronic devices.

  • This paper studies the style emergence of Liujin Dougong in the ancient Chinese architecture. Dougong is the bracket set of the ancient Chinese wood structural architecture, and Liujin Dougong is one of the late styles of Chinese Dougong. It emerged in the period of the Ming Dynasty and has been installed in imperial palaces and imperial temples till the late period of the Qing Dynasty. Through the long term field survey and documental investigation, this research found out the some prototypes of Liujin Dougong among the earlier Xia-ang style Dougongs in the Song and Yuan Dynasty architectures. The symptom of style change appeared in the bracket composition. In the beginning, because Shuatou, the horizontal member just on Xia-ang was needed to be fixed to the inner main structure system, it was changed to the diagonal member and replaced Xia-ang. It brought continuous changes, the other horizontal members of Dougong also began to change to the diagonal form. And in accordance with these compositional changes of Dougong members, the decoration of inner parts also began to change. This paper analyzed every step of the compositional and decorative changes from Xia-ang Dougong style to Liujin Dougong style. In the addition, it also proposed the typical model of Qing style Liujin Dougong of which tail end is not placed on the beam and is just placed under the purlin, based on the its own research and analysis.

  • This paper examines the Chinese government's response to four epidemic crises, including COVID-19, and analyzes the similarities and differences in these responses. It argues that while the Chinese government learned from previous epidemics and improved its handling of subsequent outbreaks, a significant variation occurred during the COVID-19 pandemic, which had a detrimental impact globally. Existing scholarly research on China's epidemic responses has often been limited in scope, focusing on individual crises and neglecting the central-local government relationship in crisis decision-making. By adopting a comprehensive approach, this paper delves into the nuanced dynamics of China's responses to these epidemics. It highlights the variations in responses, attributing them to the Chinese government's fear of undermined legitimacy and its consideration of its international image. The government's recognition of the importance of public perception and trust, both domestically and globally, has shaped its crisis management strategies. Through a detailed analysis of these factors, this paper contributes to a deeper understanding of the variations observed in China's epidemic responses. It emphasizes the significance of the central-local government relationship and the government's international image in determining its actions during epidemics. Recognizing these factors can provide policymakers and researchers with insights to shape future epidemic response strategies and foster effective global health governance.
