According to the theory of microscopic system reform in higher education, a total of 927 college students of different majors from Beijing University of Chinese Medicine were investigated by using SIMPP method. It indicated that through promoting the study of self-prepared, learning state and learning effect, students can enhance their learning ability of the admission acceptance. From the perspective of teachers, the students' self-study ability can be fully mobilized using individual person-alized teaching method. Then, the initiative of university education in the teaching and learning can be improved. Ultimately, the efficiency of student learning can be improved.

Interest in learning can not only stimulate students' enthusiasm for learning, but also directly affect the quality of higher education. In this paper, the questionnaire of the related factors of college students' interest was designed to carry out micro-system engineering research. The factors as-sociated with college students' interest in learning and their complex relationships were investigated by using methods of systems science and systems engineering. The results shows that the students who can actively participate in after-school learning discussions , feel good in lectures and have clear learning objectives, are interested in learning. And at the same time, the teacher's influence and his active guidance in classroom teaching will raise students' interest in learning. This study provides a more comprehensive basis and clues to improve students' interest in learning and education reform.

OBJECTIVEThis study aims to construct a long-term, osteogenesis-targeting HU-308 drug delivery implant by the layer-by-layer electrostatic self-assembly (LBL) technique, and observe the features of its delayed release in vitro.

METHODSA heparin (Hep) and chitosan (Chi) multilayer was coated on pure titanium using the LBL technique, and the titanium implants were dipped into the solution to load HU-308. The amount of loaded drug and release rates were measured using a UV-Vis spectrophotometer. The relationships between the loading efficiency, release time, and multilayer films were evaluated. The morphology of all the multilayers was characterized by scanning electron microscopy (SEM) and atomic force microscopy (AFM).

RESULTSThe results showed that the Hep/Chi self-assembly multilayer was gradually fabricated on the titanium surface. HU-308 was successfully loaded on the titanium implants. The amount of loaded drug increased with the amount of multilayer films, except in the T20 group. In vitro drug release study showed that drug release was more difficult in the system with thicker films, and large amounts of multilayer films decreased the release speed. Both SEM and AFM measurements showed typical LBL deposition of Hep and Chi.

CONCLUSIONThe HU-308 drug delivery implant is successfully fabricated via LBL technology. It could provide sustained release of HU-308 over 30 d. This type of implant may provide a new possi- bility of promoting implant-bone osseointegration for osteoporotic patients.

Objective To investigate the expressions of NBS1 mRNA and protein in the salivary gland of irradiated rats and explore the role of NBS1 in the repair of radiation injury of salivary gland epithelial cells.Methods Eighty rats were randomly divided into two groups for radiation and control (n =40 each).The rats were fractionally exposed to 3 Gy of 60Co γ-rays once in two days,leading to an accumulation dose of 3,6,9,12,15 Gy.The sham-irradiated controls were anesthetized in parallel but without irradiation.After 2-4 h of irradiation,the rats were sacrificed,IHC and RT-PCR were used to detect the expressions of NBS1 protein and mRNA in parotid and submandibular glands,and the ultra-structural changes in the glands were observed by a transmission electron microscopy.Results After irradiation,the salivary glands became atrophy and the parotid gland cells were damaged more serious than the submandibular gland cells.Compared with the controls,with the groups of dose,at 9,12,15 Gy in parotid gland (t =7.10,17.93,20.86,P ＜ 0.05),at 12,15 Gy in the submandibular gland (t =3.13,7.53,P ＜0.05),the expression of NBS1 mRNA was reduced.With the groups of dose at 9,12,15 Gy in paretid gland (t =4.29,17.91,91.29,P ＜ 0.05 ),the dose at 12,15 Gy in submandibular gland ( t =4.61,11.84,P＜0.05),the expression of NBS1 protein in serous cells,and the dose at 12,15 Gy in parotid gland ductal epithelial cell ( t =3.09,5.62,P ＜ 0.05) were reduced.But in the ductal epithelial cells as well as muoass cells in the submandibualr gland were steadily.Conclusions After irradiation,NBS1 at both protein and mRNA levels was dropped in the salivary gland of rats,which might contribute to the repair of radiation injury of salivary gland.

Objective To investigate the correlation of hepatitis B patients in Fuzhou between resistance patterns in HBV P region and genotype,HBeAg,the hepatitis B process.Methods This was a retrospective study.The serum and clinic data of 1 115 hepatitis B patients were collected from the inpatient and outpatient Center for Liver Diseases in First Affiliated Hospital of Fujian Medical University between October 2011 and January 2015.HBV DNA was extracted and sequenced using the Sanger method to detect HBV genotype and resistance mutations in P region,HBeAg and HBeAb concentration were detected by chemiluminescent assay.The relationship between P region resistance mutations pattern,HBV genotype,serum HBeAg and the hepatitis B process was analyzed.The x2-test was used to compare the resistance rate and positive rate.Results There were significant differences between 14 kinds of resistance loci and the genotype distribution(x2 =30.788,P =0.004),the C/B genotype ratio of three common resistance loci (rtM204V/I,rtL180M,rtA181T/V) were 85/82,49/25 and 27/9,respectively,which in genotype C was higher than genotype B.The resistance ratio of hepatocellular carcinoma,liver cirrhosis,chronic hepatitis B,hepatitis B carriers was 31.4％ (11/35),37.6％ (65/173),27.3％ (146/535) and 21.8％ (43/197),respectively,which showed significant difference between the four clinical diagnosis (x2 =11.858,P =0.008).The highest percentage of resistance was liver cirrhosis,followed by hepatocellular carcinoma and chronic hepatitis B.There was significant difference in the distribution of HBV genotype between HBeAg (+) group and HBeAg (-) group (x2 =11.093,P =0.001),the HBeAg positive rate in genotype C [37.53％ (295/786)] was higher than in genotype B[35.62％ (280/786)].However,the total resistance rate between HBeAg (+) group and HBeAg(-) group was not significantly different[23.7％ (136/573) and 24.6％ (52/211),respectively,x2 =0.07,P =0.791].Conclusions HBV genotype was related to the resistance rates,HBeAg levels and the progress of hepatitis B.The resistance rate and HBeAg positive rate of genotype C were higher than those of genotype B,and clinical outcomes were worse in genotype C.HBV resistance rates and HBeAg levels were related to the progress of hepatitis B,the higher the resistance rates,the worse clinical outcomes.

AIM: To investigate the biological characteristics of cytokine-induced killer (CIK) cells in vitro METHODS: The non-adhere peripheral blood monoclear cells from healthy donors were induced into CIK cells in the presence of IFN-?, IL-1?, IL-2 and anti-CD3 antibody. LAK (lymphokine activated killer) cells were prepared as a control. The cellular phenotype were detected by FCM and immunocytochemistry and the cytotoxicity was measured by LDH release assay. RESULTS: After 2 weeks of induction, the proliferation rate of CIK cells reached a peak and the proportion of CD3 + population was above 95%, and then the cells growth entered to plateau phase at week 3. The proportion of CD3 +CD56 + NKT subset cells was 16 5% on day 15 and it had no obvious variety between 2 and 4 weeks. Correspondingly, LAK cells grew slowly and had lower proliferation rate compared with the CIK cells ( P
