Objective To analyze the effects and experience of ideological and political education through inquiring students' satisfaction on it,and to strengthen innovation and efficiency. Methods Five hundred and fifty university students were chosen by random.Through anonymous questionnaires,information on attention and satisfaction of ideological and political education about educate by all staff,campus culture,psychological status,and extracurricular activities were acquired.Results More than 56% of the students thought who impressed them most were the professional teachers;and 75.64% of them would ask friends for help when they were facing difficulties.And 44.91% considered study as the main resource of pressure,although the other 39.09% chose the career perspective.Then,57.45% were willing to take part in the meaningful activities after class,though the study was tough.And 45.45% hoped it would be a great progress on extracurricular activities;74% would take part in entertainment,and on the other hand 68.55% chose volunteer;and 87.72% interested in learning psychological knowledge. Conclusion It is important to strengthen and develop ideological and political education among students in the university.And attention should be paid to the innovation and efficiency of the education.

BACKGROUND: Fibrin glue has been demonstrated to function as a kind of biomaterial with high quality. It has been used in nerve tissue engineering and proved to be a kind of scaffold for some cells.OBJECTIVE: To explore the biocompatibility of fibrin glue and olfactory ensheathing cells (OECs).DESIGN, TIME AND SETTING: An in vitro control trial based on cytology was performed at the Institute of Neurobiology,Nantong University from August 2007 to February 2008.MATERIALS: Fibrin glue was made of fibrin and catalyst, and OECs derived from rats' olfactory bulb were normally primary-cultured.METHODS: OECs were divided into control (OECs clone spheres were cultured alone) and in fibrin glue (OECs clone spheres were cultured and combined with fibrin glue) groups. After 1 week of culture, the proliferation of OECs were observed by convert microscope and detected by S-100 immunofluorescence histochemical staining.MAIN OUTCOME M EASURES: OECs morphology, cell count, the area of the cell bodies and the perimeter of the cell were determined.RESULTS: OECs could survive, migrate in fibrin glue, and float in the fibrin glue in the lower layer. After 7 days of incubation, cell body exhibited fusiform or triangle, predominantly bipolar or bipolar. The number of the S-100 positive cells was more, and cell bodies were larger in fibrin glue group than control group (P < 0.05). However, there was no obvious difference between two groups in cell perimeter (P > 0.05).CONCLUSION: Fibrin glue has good biocompatibility with OECs, and OECs can survive and migrate in fibrin glue.

Objective To investigate the expression levels of DNA methyltransferases 1, 3A and 3B in CD4+ T cells of MRL/lpr mice, and explore their relationship with the expression levels of methylation-sensitive genes (ITGAL, CD70). Methods CD4+ T ceils were isolated from spleens of 16-week-old MRL/lpr and BALB/c control mice by anti-CIM antibody labeled magnetic beads. Transcription levels of DNA methyhransferases 1, 3A and 3B and methylation-sensitive genes(ITGAL, CD70) were measured by real-time mice when compared with BALB/c control mice and the difference was significant (P<0.05), while the expression of DNMTI and DNMT3A showed a tendency of decrease (P>0.05). The mRNA expression of CD70 was significantly higher (P<0.01), but the expression of ITGAL had no significant difference between the two P<0.01 ). Conclusion Decreased expression of DNMT3B may attribute to the elevated expression of methylation-seusitive gene CD70, thus lead to the dysfunction of CD4+ T cell and play an important role in the pathogenesis of SLE.

To investigate the anticancer effects of ring C in 18β-glycyrrhetinic acid (GA), a series of GA derivatives featured with 9(11)-ene moiety in ring C were designed and synthesized. The structures were confirmed by IR, LC-MS and 1H NMR. Their inhibitory effects towards human prostate cancer PC-3 and leukemia HL-60 cell lines were determined. Most of the derivatives displayed stronger antiproliferative activities than GA. Particularly, compound 14 showed promising anticancer activity with the GI50 values of 4.48 µmol · L(-1) and 1.2 µmol · L(-1) against PC-3 and HL-60 cells respectively, which is worth further study.

In this paper, Liuwei Dihuang pill was used to study the identification of Chinese patent medicine by fluorescence sequencing typing technology. The DNA of Paeonia suffruticosa was used as template to amplify by five pair of FAM fluorescence labeling primers. Then, the amplified products were sequenced. The sequencing results were analyzed by GeneMarker V1.80 to screen the best fluorescence labeling primers. As a result, psbA-trnH fluorescence labeling primer was used to identify the raw materials of Liuwei Dihuang pill. The results showed that three kinds of raw plant medicinal materials in Liuwei Dihuang pill were able to be correctly identified by psbA-trnH fluorescence labeling primer. The fluorescence sequencing typing technology can stably and accurately distinguish raw medicinal materials in Chinese patent medicine.

OBJECTIVE:
To investigate the correlation betwen varying degrees of non-acute tinnitus and anxiety and depression.
METHOD:
Seventy-seven outpatients with non-acute tinnitus as their in chief complaint were submitted to Tinnitus Handicap Inventory(THI), Self-Rating Anxiety Scale(SAS), and Self-Rating Depression Scale (SDS).
RESULT:
THI and its three subscales were found to have significant correlations with SAS and SDS. The group (THI ≥ 38) had more anxiety and depression than the mild (THI < 38). Significant correlations were also observed between THI, SAS and SDS in the group with THI ≥ 38, in contrast with the group of THI < 38.
CONCLUSION
Patients with THI ≥ 38 suffered from severe anxiety and depression than the mild. Doctors should pay more attention to these patients, especially their psychological disorders.

Objective To compare three kinds of irradiation treatment plans for cervical and upper thoracic esophageal cancer,in order to arrived at proper decision for the patient.Methods From February 2001 to June 2004,43 such patients were studied with three different simulated treatment plans made including conformal plan,conventional four-field plan and conventional two-field plan for every one.All plans were evaluated with iso- dose curve and dose-volume histogram.Results GTV on 95% isodose curve was 99.5%,98.2% and 87.4% in conforaml plan,conventional four-field plan and conventional two-field plan,respectively;PTV_1 and PTV_2 on 95% isodose with 97.8%,97.2%,94.8% and 95.8%,86.6%,73.7%.The volume of>20 Gy dose of left lung accepted was 18.6%,17.2% and 32.3%,in conformal plan,conventional four-field plan and conventional two-field plan,respectively;the right lung received 20.5%,19.9% and 35.5%.Conclusions Conformal plan is the best in radiotherapy,as it can provide ideal dose distribution of irradiated target with adequate protection of the normal tissues.Conventional four-field plan,being easy to carry out,can replace the conformal plan in most situations.Conventional two-field has the most uneven dose distribution and largest lung volume irradiated.
