Objectives: The Qing Dynasty experienced a development in Yunqi even greater than in the Ming Dynasty. Popularization and universalization of Yunqi theory led to many books on the subject published, especially with weights on Warm Heat Disease and Pestilence, also giving birth to new Yunqi theories. A study into this development has a great significance in the study of the traditional medicine in Qing. Methods: The paper studies the Yunqi books published in the Qing dynasty to find out the unique characters of those books. To understand the direction which the Yunqi theory in the Qing period took, the paper also reviewed the positions of different groups, those who were favorable, those who compromised, and those who were unfavorable. Results: Four directions were taken by the study of Yunqi in the Qing period. First is the systemic study and composition of Neijing's chapter of Yunqi. This direction was taken by Liumaoxiu's NeiJingYunQiBingShi) and $N{\grave{e}}ijingyunqibiao$, Xuefuchen's Suwenyunqitushuo, Zhuenhua's Suwenyunqiqianshuo, an unknown person's Su wen yunqi chao, Weigeliu's Neijingqihuapian. The second direction is the study of Yunqi in relation with the Warm Heat Disease and Pestilence, which was taken by Mayin lin's Wuyunliuqiwenyifayuan, Lumaoxiu's Suwenyipianbìngshi, Litianchi's Shiyiwenbingqìyunzhengyan lun, and Wangxun's Cihangsanyuanfujifang. The third direction deals with a new Yunqi theory. The Fourthis the explanation of Yunqi in the form of Songs, which was taken by Wuqian's Yunqiyaojue, and Wengzao's Yunqiyaojue. Conclusions: Ludanchen published Yunqibian, and explained that Haizichouyinmaochen, which is the eclipse's south latitude, becomes Nanzheng, and Southern government, which is the eclipse's north latitude, becomes Northern government. Lumaoxiu revealed that the Liuqidasitian, founded by Wangpuzhuang, his great grandfather on the mother's side, is in alignment with the theory of Dashitian, used by Liushozhen, Lidongyuan, Zhudanxi, and Zhangjingyue. The representative figure in the favorable view of Yunqi in the Qing period is Wuyang, that of those who compromised is Fengzhaozhang, and that of opposition is Zhangzhuo.

"Beijijiufa" is a medical book republished by Sun Ju Qing in 1245. He compiled this book having added "Qizhumajiufa" and "Zhugejingyanbeijiyaofang" to the contents of "Beijijiufa" authored by Wen Ren Qi Nian. In "Beijijiufa" the author described treatment methods making use of moxibustion methods in connection with 22 cases of acute diseases. The author had collected the moxibustion methods used to treat acute diseases, which had been practiced by the medical practitioners of many generations, and quoted total 13 medical men's practices. In the book, the greatest parts of details were quoted especially from the writings of Sun Si Miao and Ge Hong, and this shows that the medical philosophies of both Sun Si Miao and Ge Hong were reflected onto "Beijijiufa". He had differed on his moxibustion practice: the size of moxa wool, the number of moxibustion treatment, and method of moxibustion for male and female were differed from one another according to the disease. As to the area of moxibustion, he chose the body parts around under four limbs and joints, and mostly used extraordinary acupoints rather than twelve main meridians. In his descriptions of finding meridian points, he did not describe it by its specific name of the reaction point, but explained the location of moxibustion points in detail through pictures. "Qizhumajiufa" is related to moxibustion method and prescriptions to treat surgical diseases, like skin boils or furuncle on the back, etc. He easily explained the method to find the meridian points for moxibustion treatment by using particular way through diagrams and pictures. Eight prescriptions he used were the collections among the historical practices of medical practitioners of many generations for skin boils which showed excellent therapeutic actions. In "Zhugejingyanbeijiyaofang", there are prescribed for 36 disease, also is the records of treatment methods for medical emergency which would be encountered easily in everyday life. As to therapeutic remedies, varied treatment methods, including the treatment by means of pasting and attaching medicinal substance to the spot, the treatment by means of mixing medicinal substance with alcoholic beverage, cleansing method, smoke inhalation remedy etc. were introduced. In "Beijijiufa" moxibustion was regarded as a top priority for treatment of acute disease, and the author strived to present remedies to the readers as easily as possible through 19 pictures. Regarding prescriptions, the author introduced diverse treatment methods with respect to various disease symptoms, and described the method to treat disease symptoms making use of medicinal ingredients which can easily be found in daily life. Likewise, "Beijijiufa" compiled by Sun Ju Qing was intended for clinical practice, and was indeed a medical book having been utilized for treatment of acute diseases in those days.

From all possible chinese medical literatures, I studied the history of chinese pediatrics by dividing into Chunqiu Zhanguo, QinHan dynasties, LiangJin, SuiTang five dynasties, Song Dynasty, Jin and Yuan dynasties, Ming Qing dynasties. The conclusions are summarized as followings 1. The mentions related with pediatrics existed already in Yan ruins turtle shell letters, and 〈Yellow Emperor's classic of internal medicine> in Chunqiu Zhanguo time formed the system of medicine, established the theoretical foundation. 2. Chang Ji established the system of diagnosis and treatment based on overall analysis of symptoms and signs in , and later pediatricians commonly applied his prescriptions to the febrile diseases. 3. The period from LiangJin to SuiTang, Pediatrics was established as special department then in , Chao Yuanfang stated the etiology, pathogenesis, symptomatology of pediatric diseases. 4. In Song dynasty. pediatric 4 major, symptoms that had been mentioned from SuiTang dynasties, were clearly established, pediatrical special books were published, and written by Qian Yi who is considered as the founder of chinese pediatrics, established the foundation of pediatrical division formation in distinction from adult fields. 5. In Jin and Yuan dynasties, four eminent physicians established the actual relationship between the theories and practical applications and insisted various and creative theories based on the classical medicine, for example, the theory that fire and heat in the body was the main cause of diseases of Liu Wansu purgation theory of Zhang Congzheng, qi regulating theory of Liu Gao, ministerial fire theory and the theory that yang is ever in excess while Yin is ever deficient of Zhu Zhenheng, etc, and they applied those theories to pediatrical various sides. 6, In Ming Qing dynasties, pediatrical specialists and pediatrical publications had increased, eg, father and son Xue Kai Xue Ji, Wan Quan, Lu Bai-si, etc in Ming dynasty, Ye Gui, Chen Fuzheng, Xia Ding, etc in Qing dynasty were famous as pediatricians. Specially, the doctrine of epidemic febrile diseases at that time showed prominent effects to children's epidemic febrile diseases.

Rhomboids were identified as the first intramembrane serine proteases about 10 years ago. Since then, the study of the rhomboid protease family has blossomed. Rhomboid domain containing 1 (RHBDD1), highly-expressed in human testis, contains a rhomboid domain with unknown function. In the present study, we tested the hypothesis that RHBDD1 was associated with proliferation and apoptosis in hepatocellular carcinoma using recombinant lentivirus-mediated silencing of RHBDD1 in HepG2 cells. Our results showed that down-regulation of RHBDD1 mRNA levels markedly suppressed proliferation and colony formation capacity of HepG2 human hepatoma cancer cells in vitro, and induced cell cycle arrest. We also found that RHBDD1 silencing could obviously trigger HepG2 cell apoptosis. In summary, it was demonstrated that RHBDD1 might be a positive regulator for proliferative and apoptotic characteristics of hepatocellular carcinoma.

To analyze the growth, proliferation, apoptosis, invasiveness and chemotherapy sensitivity of EC9706 cells after K-Ras gene silencing, an expression carrier pSilencer-siK-Ras was constructed, and the EC9706 cell line was transfected using a liposome technique. Six groups were established: Control, siRNA NC (transfected with empty vector pSilencer2.1); Ras siRNA (transfected with pSilencer-siK-Ras2); Paclitaxel; Paclitaxel + siRNA NC; and Ras siRNA + Paclitaxel. After the treatment, RT-PCR, Western blotting, MTT assay, flow cytometry and the Transwell technique were used to assess expression of K-Ras mRNA and protein in EC9706 cells, as well as cell growth, proliferation, apoptosis and invasiveness. The effect of Paclitaxel chemotherapy was also tested. pSilencer-siK-Ras2 effectively down-regulated expression of K-Ras mRNA and protein in EC9706 cells, growth being significantly inhibited. Flow cytometry indicated obvious apoptosis of cells in the experimental group, with arrest in the G1 phase; cell migration ability was also reduced. After pSilencer-siK-Ras2 transfection or the addition of Paclitaxel, EC9706 cells were suppressed to different extents; the suppressive effect was strengthened by combined treatment. The results suggested that RNAi-induced K-Ras gene silencing could enhance chemotherapy sensitivity of esophageal cancer.

Plk 1 is overexpressed in many human malignancies including laryngeal carcinoma. However, its therapeutic potential has been never examined in laryngeal carcinoma. In the present study, a simple cellular morphology-based strategy was firstly proposed for rapidly screening the effective siRNAs against Plk1. Furthermore, we investigated the effects of Plk1 depletion via a novel identified effective siRNA against Plk1, Plk1 siRNA-607, on human laryngeal carcinoma Hep-2 cells. The results indicated that Plk1 siRNA-607 transfection resulted in a significant inhibition in Plk1 expression in cells, and subsequently caused a dramatic mitotic cell cycle arrest followed by massive apoptotic cell death, and eventually resulted in a significant decrease in growth and viability of the laryngeal carcinoma cells. Taken together, our present study not only suggests a simple strategy for rapidly screening effective siRNAs against Plk1 but also implicates that Plk1 may serve as a potential therapeutic target in human laryngeal carcinoma.

Objective: To explore the effect on radiosensitivity of arsenic trioxide ($As_20_3$) in conjunction with hyperthermia on the esophageal carcinoma EC-1 cell line. Method: Inhibition of EC-1 cell proliferation at different concentrations of $As_20_3$ was assessed using the methyl thiazolyl blue colorimetric method (MTT method), with calculation of $IC_{50}$ value and choice of 20% of the $IC_{50}$ as the experimental drug concentration. Blank control, $As_20_3$, hyperthermia, radiotherapy group, $As_20_3$ + hyperthermia, $As_20_3$ + radiotherapy, hyperthermia + radiotherapy and $As_20_3$ + hyperthermia + radiotherapy groups were established, and the cell survival fraction (SF) was calculated from flat panel colony forming analysis, and fitted by the 'multitarget click mathematical model'. Flow cytometry (FCM) was used to detect changes in cell apoptosis and the cell cycle. Results: $As_20_3$ exerted inhibitory effects on proliferation of esophageal carcinoma EC-1 cells, with an $IC_{50}$ of 18.7 ${\mu}mol/L$. After joint therapy of $As_20_3$ + hyperthermia + radiotherapy, the results of FCM showed that cells could be arrested in the $G_2$/M phase, and as the ratio of cells in $G_0/G_1$ and S phases decreased, cell death became more pronounced. Conclusion: $As_20_3$ and hyperthermia exert radiosensitivity effects on esophageal carcinoma EC-1 cells, with synergy in combination. Mechanistically, $As_20_3$ and hyperthermia mainly influence the cell cycle distribution of EC-1 esophageal carcinoma cells, decreasing the repair of sublethal damage and inducing apoptosis, thereby enhancing the killing effects of radioactive rays.
