Head and neck surgery is a relatively young discipline. Since 1937,it has made important advances. In the past, the patients had to sacrifice their involved organs in order to survive, but now we have to think not only of the survival rate of the patients,but also should pay more and more attention to improve their quality of life. The plan of treatmant must consider multimodality therapy and function preservation. To attain this goal, we should pay attention to laparoscopic surgery and sentinal node biopsy as well as possibility of gene therapy in head and neck tumors. In addition, we should investigate to application of molecular biology in head and neck surgery.

Objective To analyze the change in immune function and therapeutic effectiveness of children with im-mune thrombocytopenic purpura and Helicobacter pylori(H. pylori)infection. Methods Eighty hospitalized chil-dren with thrombocytopenic purpura between March 2011 and March 2012 were as observation group,and then sub-divided into infected group and non-infected group according to whether they were infected with H. pylori;80 healthy children were as control group . Lymphocyte subsets ,clinical therapeutic effectiveness and recurrence rate among three groups were compared. Results The positive rate of H. pylori in observation group was significantly higher than control group(55.00% [44/80]vs 2.50% [2/80];χ2= 12.48,P= 0.008). There was significant differences in CD4+,CD4+/CD8+ ,and CD19+T lymphocyte among three groups (all P<0.05);CD4+ and CD4+/CD8+ T lymphocyte in infected group was significantly lower than non-infected group respectively ([13.40±4.65]% )vs [28.56± 3.82]% ;[0.69±0.18]% vs [1.04±0.23]% ),and CD19+T lymphocyte in infected group was significantly higher than non-infected group ([45.21±10.20]% vs [22.05±2.23]% );CD4+ and CD4+/CD8+T lymphocyte in non-in-fected group and infected group was significantly lower than control group ([40.20±3.42]% ,[1.54±0.42]% respec-tively),and CD19+T lymphocyte was significantly higher than control group ([11.02±2.89]% ). The overall therapeu-tic effectiveness in infected group and non-infected group was 90.91% and 91.67% respectively(P>0.05). The recur-rence rate of thrombocytopenic purpura after anti-H.pylori infection therapy in infected group was significantly lower than non-infected group (20.45% vs 30.56% ;χ2= 6.396,P= 0.038). Conclusion Detection of immune function is helpful for clinical diagnosis of H. pylori infection associated with immune thrombocytopenic purpura .

Objective To investigate the expression of ICAM-1 and VCAM-1 in colorectal carcinoma and the rela-tionship between ICAM-1, VCAM-1 and the occurrence, the metastasis of colorectal carcinoma, and to analyze the significance. Methods Immunohistochemistry staining(S-P method) was used to detect the expression of ICAM-1 and VCAM-1 on consecutive section in 78 cases of colorectal carcinoma and normal mucosa and 42 cases of colorec-tal adenomas. Plasma was obtained from 78 patients with colorectal carcinoma and 40 healthy volunteers prior sur-gery, by an enzyme-linked immunosorbent assay (ELISA). Results There was significant difference between the high expression of ICAM-1 and VCAM-1 in colorectal carcinoma and the low expression in normal mucosa and ade-noma(P < 0. 01). Serum ICAM-1 and VCAM-1 were significantly higher in patients with colorectal carcinoma than those in normal control group(P < 0. 01). The ICAM-1 and VCAM-1 levels were not related to sex, age, tumor lo-cation and histological grades(P > 0. 05),but had significantly statistical difference between lymph node metastasis and Dukes stage(P < 0. 01). Conclusion The increase expression of ICAM-1 and VCAM-1 in colorectal cancer suggests that the ICAM-1 and VCAM-1 may play an important role in evaluation of malignant degree and judging the progress as well as the mechanism of colorectal cancer.

OBJECTIVE:To prepare Stemoninine orally disintegrating tablets,and to optimize its formulation and preparation technology. METHODS:Direct powder compression method was used to prepare Stemoninine orally disintegrating tablets. Using material angle of repose,disintegration time and taste evaluation as index,single factor test was used to screen several factors as bulking agent,disintegrating agent,glidant and flavoring agent;using disintegration time as index,L9(34) orthogonal test was used to optimize the formulation with ratio of MCC+mannitol,PVPP,silica powder and aspartame+stevia as factors. Validation test was also conducted. RESULTS:Optimized formulation was that MCC+mannitol(1∶1)was 50%,PVPP was 20%,silica powder was 2% and aspartame+stevia(10∶1)was 7%. 3 batches of prepared Stemoninine orally disintegrating tablets were smooth in sur-face and good in taste;their disintegrating time was(22.6±2.1)s,and weight variation,hardness,contents were within the speci-fied range (all RSD≤0.97%,n=3). CONCLUSIONS:The formulation and technology of Stemoninine orally disintegrating tab-lets are reasonable,and the quality indexes are all in line with the requirements of orally disintegrating tablets.
