Alzheimer′s disease ( AD) is the most common disease leading to dementia .With aging of the population , the morbidity of AD is increasing significantly , which brings serious burden personally and socially .So the early diagnosis of AD has be-come the hotspot in the current research field .In order to highlight new ideas for the early diagnosis of AD , the current review will ana-lyze from the first international diagnostic criteria for AD dementia to the latest conceptual framework for research on subjective cogni -tive decline in preclinical Alzheimer′s disease.

Objective To investigate the clinicopathological features of thymic neuroendocrine carcinoma and its differential diagnosis. Methods Clinicopathologic analysis and immunohistochemical staining were performed in 5 cases of TNC. Results For 5 cases TNC, 3 cases occurred in men, 2 cases occurred in women. The average age was 46.8 years. They were with chest symptoms before operation. 3 cases were Ⅱ and 2 cases were Ⅲ by clinic stages. Grossly , the tumors were gray in color with areas of hemorrhage and necrosis. Histopathology of well differentiated 2 cases and poorly differentiated 3 cases. Immunohistochemically, the tumor cells were positive for CK, NSE, SyN and CgA. 3 cases were positive for PCNA, Ki67, p53. Conclusions TNC has a pleomorphic appearance of histological features with well, moderate and poorly-differentiated areas. Immunohistochemical staining is helpful in the differential diagnosis of TNC from other tumors derived from the thymus. Neither grading as neuroendocrine carcinomas nor any individual histologic parameter showed a significant association with prognosis. Initial aggressive treatment, including complete surgical excision and adjuvant radiotherapy, appears to offer the best hope for prolonged survival. Adjuvant chemotherapy also should be considered, because the incidence of distant relapse is high.

Objective To investigated the efficacy of celecoxib for postoperative analgesia after endoscopic nasal surgery. Methods One hundred and twenty ASA Ⅰ or Ⅱ patients of both sexes aged 18-64 yr were randomly assigned to one of three groups ( n = 40 each): control group ( group C); celecoxib 200 group ( group CEL1 ) and celecoxib 400 group ( group CEL2 ). The patients took celecoxib 200 and 400 mg by mouth at 1 h before induction of anesthesia in group CEL1 and CEL2 respectively. Anesthesia was induced with midazolam,propofol, remifentanil and rocuronium and maintained with iv propofol and remifentanil infusion. VAS was used to assess postoperative pain (0 = no pain, 10 = worst pain). In PACU when VAS score ≥3, the patients were given fentany125 μg iv every 5-10 min until the VAS score ＜ 3. After being discharged from PACU, the patients received celecoxib 200 mg every 12 h for 5 days in the 2 celecoxib groups. Oxycodone 5 mg was used as rescue analgesic when VAS score ≥ 4 until the VAS score ＜ 4. The number of patients who needed fentanyl for analgesia in PACU, the number of patients who needed oxycodone within 6 h, 6-24 h and day 2-5 after operation and side effects after operation were recorded. Analgesic efficacy was assessed at day 5 after operation and the satisfactory rate of patients calculated. Blood samples were obtained at 0, 6 and 48 h after operation for determination of PGE2,6-k-PGF1α and TXB2 concentrations. TXB2/6-k-PGF1α was calculated. Results The number of patients who needed fentanyl in PACU and the number of patients who needed oxycodone within 6 h and 6-24 h after operation were less, the satisfactory rate was significantly higher, and PGE2 concentrations in blood were significantly lower at 48 h after operation in the 2 celecoxib groups than in group C ( P ＜ 0.05 or 0.01 ). There was no significant difference in each index between the 2 celecoxib groups ( P ＞ 0.05 ). There was no significant difference in TXB2/6-k-PGF1α at each time point among the three groups. Nausea and vomiting occurred in one patient after operation in group C, but side effects were not observed in the 2 celecoxib groups. Conclusion Celecoxib given before and after operation can effectively relieve postoperative pain after endoscopic nasal operation by reducing PGE2 concentrations in blood.

The plysical and chemical characteristics of recombinant human GM - CSF (rhGM - CSF) were studied separatly. rhGM - CSF was treated by GdHCl, reduced by DTT, and the disulfide bond was blocked by idoacetamide. The results showed that the samples aren' t homogeneous in UV absorption spectrum and RP-HPLC analysis after treatment by DTT. There was no remarkable differences in the results of the analysis of SDS-PAGE electrophoresis and western blot between treated and untreated rhGM - CSF samples. The effect of GdHCl on GM-CSF was reversible in all above tests; In peptide mapping analysis, the digestion of the samples with blocked disulfide bond by CNBr and protease is more complete than that without any treatment.

Objective To observe anti-sense phosphorothioate oligonucletide (ASPSODN) targeted directly to hTERT mRNA to its inhibiting effect on aimed gene and the influence on the telomerase activity, cellular proliferation, cell apoptosis of K562 cells. Methods Human leukemia cell line K562 was transfected with anti-sense oligonucleotide ASPSODN by liposome. The proliferation activity of K562 cell line was determined by using methyl thiazolyl tetrazolium assay, and telomerase activity was detected by TRAP-PCR-ELISA. Flow cytometry was adopted to examine apoptotic rate and cell cycle. RT-PCR was used to detect the expression of target gene hTERT mRNA. Results 0.6 μmol/L ASPSODN (0.42 ±0.16) was remarkably decreased the expression of hTERT mRNA, Telomerase relative activation was decreased by 52 %. According to 0.6 (μmol/L ASPSODN caused significant the inhibition of K562 cell growth. Apoptotic rate and cell cycle was examined by 0.6 μmol/L ASPSODN with flow cytometry. The cell apoptosis rate of 0.6μmol/L ASPSODN were 10.31 %. It showed the cells treated with 0.6 uU PSASODN arrested in G_1/C_0. The ratio of cells in G_2/M and S period was reduced. But there was no characteristic apoptosis peak. Conclusion ASPSODN targeted hTERT can inhibit the expression of target gene hTERT mRNA, and decrease the telomerase activity of K562 cells. ASPSODN can inhibit strongly the proliferation of K562 cell and induce cell apoptosis by decreasing telomerase activity.

The adjustment of Laboratory Medicine to the first class subject is both challenges and opportunities. In order to meet the requirements of the modern laboratory medicine on the improved knowl-edge and skill, Weifang Medical University sets a goal of cultivatinghigh-qualified and applicative profes-sional personnel of Laboratory Medicine Science. To realize that, we build a new curriculum system with features of Medical Laboratory Science, including the theoretical curriculum system and the practical teach-ing system. The theoretical curriculum system breaks the traditional framework of the old curriculum which designed according to the discipline category, builds a new curriculum system of platform and module, scientifically integrates the basic course group in clinical laboratory medicine, and adds the course of clinical examination skills with its own professional characteristics. In the practical teaching system, we focus on the cultivation of practice ability and innovation ability, encourage the students to go to the hospital and company earlier, and promote the integration of production, teaching and research in various approaches.
