The primary focal area of carcinoma of unknown primary (CUP) can not be determined by clinical examination.It is difficult to find the primary site and its prognosis is poor.The traditional diagnostic approaches mainly include pathological examination,endoscopy,imaging technology and so on.However,positron emission tomography is the preferred approach.In recent years,gene expression profiling has become a new diagnostic approach to find the source of CUP.The detection rate by gene expression profiling is high,and the approach can accurately identify the primary site.The recommended therapies include classic platinum-or paclitaxel-based chemotherapy,radiotherapy or surgery,and site-directed therapy by gene expression profiling for patients with CUP improves their survival rate.

Objective To explore the role of team-based learning(TBL)in the teaching of pe-riodontics for undergraduates. Methods Totally 38 2008 grade undergraduates majored in stomatology were divided into six groups according to previous test scores. Individual test,group test and group re-sponder were conducted successively . Average test scores before and intra class were calculated and questionnaires survey was conducted after the course. Results There was no significant correlation be-tween average test scores intra class and basic knowledge and preview effect(r=0.028,P>0.05). Ques-tionnaire survey demonstrated that learning motivation,learning interests,knowledge mastering and com-munication ability of students were significantly improved. Conclusion TBL teaching promotes the class-room atmosphere and improves team collaboration and learning enthusiasm. Students show high accep-tance for this new teaching modes,so it can be tried in the teaching of stomatology.

Objective To investigate the effects of 5-azacytidine on radiation-induced epithelialmesenchymal transition in rat alveolar type Ⅱ epithelial cell line (RLE-6TN) and explore their working mechanisms,and to provide experimental evidence for the potential drug-based treatment of radiationinduced pulmonary fibrosis.Methods RLE-6TN cells were cultured in vitro and divided into four groups according to the experimental purposes:control group (C),radiation group (R),5-azacytidine group (A),and radiation followed by 5-azacytidine group (R + A).The microstructural changes in cells were determined by transmission electron microscopy.Inverted phase-contrast microscopy revealed the morphological changes in cells.The mRNA expression levels of E-cadherin and α-SMA were measured by quantitative real-time polymerase chain reaction (qRT-PCR).The protein expression levels of E-cadherin,GSK3 β,and p-GSK3 β (Ser9) were measured by Western blot.The one-way analysis of variance was used for pairwise comparison.Results The cells in group R became spindle-like.Similar morphological changes were not observed in cells in group R + A.Osmiophilic lamellar bodies disappeared at last in cells in group R.RT-PCR results showed that compared with group C,group R had a significantly lower mRNA expression level of E-cadherin ((0.23 ± 0.06) vs.(1.00 ± 0.00),P =0.002)) and a significantly higher mRNA expression level of α-SMA ((2.91 ± 0.01) vs.(1.00 ± 0.00),P =0.000)).However,compared with group R,group R + A had a significantly higher mRNA expression level of E-cadherin ((0.47 ± 0.05) vs.(1.00 ± 0.00),P =0.024)) but a significantly lower mRNA expression level of α-SMA ((2.50 ± 0.02) vs.(1.00 ±0.00),P =0.037)).The results of Western blot showed that the protein expression level of Ecadherin was significantly reduced ((0.07 ± 0.01) vs.(0.48 ± 0.02),P =0.028)),while the protein expression level of p-GSK3β was significantly increased in Group R than in Group C ((0.85 ± 0.04) vs.(0.23 ± 0.03),P =0.031)).However,compared with group R,group R + A had a significantly lower protein expression level of E-cadherin ((0.25 ± 0.00) vs.(0.07 ± 0.01),P =0.024)) and significantly less up-regulation of the protein expression level of p-GSK3β ((0.39 ± 0.03) vs.(0.85 ± 0.04),P =0.014)).Conclusions X-ray radiation can induce the epithelial-mesenchymal transition in epithelial cells.5-azacytidine suppresses radiation-induced epithelial-mesenchymal transition by inhibition of the activity of p-GSK3β in RLE-6TN cells.

OBJECTIVETo observe the impacts of doxapram on anesthetic efficacy and respiratory and circulatory functions during anesthesia with remifentanil given by target-controlled infusion (TCI) combined with propofol in painless artificial abortion.

METHODSA total of 120 ASA I women requiring voluntarily painless artificial abortion were randomized into two equal groups. One group was given remifentanil by TCI at 2 ng/ml and propofol 1mg/kg (group I), and the other given remifentanil by TCI, propofol, and doxapram 0.6 mg/kg (group II). The anesthetic efficacy and respiratory and circulatory suppression during anesthesia were observed.

RESULTSBoth of the two groups showed satisfactory anesthetic efficacy with comparable the BIS values (P>0.05). No significant difference was noted in the induction time and awaking time between the two groups (P>0.05), but group I had more serious respiratory and circulatory depression than group II (P<0.05).

CONCLUSIONDoxapram may attenuate respiratory and circulatory depression during anesthesia with remifentanil given by TCI combined with propofol in painless artificial abortion, and provide comparable anesthetic efficacy.

Objective Observe the effect of Total paeony glycoside(TPG)has on the T-cell immune action and apoptosis process of Oral lichen planus patients and analyze the mechanism.Methods 20 OLP patients are recruited into this experiment, each is treated with TPG,and their clinical effect is taken notes of.Observe the apoptosis of OLP lesions from each of the patients before and after the treatment,compare the apoptosis condition and the expression of CD4 + ,CD8 + ,and the CD4 +/CD8 + ratio,to analyze the role TPG plays on the immune expression of T-cell and the effect on apoptosis process.Results TPG improve the clini-cal manifestation of OLP patients significantly,resulting in the decrease of reticulum and erosive areas,and the pain index is de-creased obviously.The expression of CD4 + and CD8 + are decreased in OLP lesions after the treatment of TPG.Conclusion TPG may induce the apoptosis of the T-cell in lamina propria of the OLP lesions to regulate the T-cell immune action of OLP patients, and slow the development of inflammatory process of OLP,and in that way,TPG shows its potential in treating OLP,and this ex-periment can provide the primary evidence.

Objective To analyze the features of health economics in the treatment of leukemia;To evaluate the improvement trend of levels of clinical diagnosis, treatment and management. Methods TCM medical information dtatabase and electronic medical system in Zhejing Province TCM Hospital from January 2010 to December 2015 were retrived. According to inclusion and exclusion criteria, leukemia patients’ materials that met the critiria were screened. The total hospitalization fees, cost of Western medicine, the cost of Chinese patent medicine, cost of TCM decoction pieces, and cost of blood transfusion were set as costs, while white blood cell count, hemoglobin concentration, and platelet count were set as effectiveness indicators for cost effectiveness analysis. Results In patients with low white blood cell count increased unit white blood cell count, patients with high white blood cell count declined unit white blood cell count, patients with low hemoglobin increased unit hemoglobin count and patients with low platelet count increased unit platelet count, the total hospitalization fees, cost of Western medicine, the cost of Chinese patent medicine, cost of TCM decoction pieces, and blood transfusionfor the above increases showed a decreasing trend. Conclusion Health economics advantages in three blood routine indicators after treatment of integrated traditional Chinese and western medicine for leukemia is increasing year by year.

To observe the dynamic change of parasites in the brains of BALB/c mice infected with Angiostrongylus cantonensis in order to explore its possible mechanism of pathogenesis', BALB/c mice infected with the III stage larvae of A.cantonensis were observed and killed in different times after infection. The number and distribution of parasites in the brains of the infected mice were observed microscopically and macroscopically. It was found that the larvae of A.cantonensis were distributed in the cerebrum and cerebellum of mice in accordance with the rule of parasitization of worms in the host, i.e.multiplication at first and then dropping in number. And the places where the parasites located were damaged due to mechanical action or inflammatory reactions. The time of onset of symptoms, such as ataxia and twitch was coincided with the dynamic changes in the brains of the infected mice.
