Objective:To evaluate the clinical efficacy between preparation porcelain veneer(PPV)and no-preparation porcelain veneer(NPPV).Methods:44 patients with 97 PPVs and 23 patients with 57 NPPVs were followed up for 3 years.Mental tension, postoperative dentin sensitivity and satisfaction of the patients,survival rate of the veneers,sulcus bleeding index(SBI)of preopera-tive and postoperative 3 years were evaluated.A comparative analysis was taken to examine the clinical indicators of 2 groups accord-ing to the modified CDA /Ryge criteria.Results:Survival rates of PPVs and NPPVs were 96.91 % and 96.49%(P >0.05),satisfac-tion rates of the 2 group patients were 95.45% and 95.65%(P >0.05),respectively.Mental tension and the postoperative dentin sensitivity of patients in PPV group was higher than those in NPPV group.Preoperative and postoperative SBI were not statistically dif-ferent between the 2 groups(P >0.05).Marginal adaptation in PPV group was better than that in NPPV group.Color matching, Porcelain surface and Marginal stain were not statistically different between 2 groups.Conclusion:Preparation porcelain veneers and no-preparation porcelain veneers both are effective in clinical application.

We report one case of pediatric acute myeloid leukemia type 2 (AML-M2) who presented with karyotypic aberration of trisomy 21 with the t(5;ll) chromosomal translocation.The patient achieved complete remission after two cycles of chemotherapy of daunorubicin,cytarabine and etoposide.Then,follow-up cytogenetic analysis from bone marrow cell cultures demonstrated a normal karyotype of 46,XY.After 9 years,the patient relapsed and the karyotypic abnormalities of trisomy 21 with t(5;ll) reappeared.It was concluded that trisomy 21 with t(5;11) is a new unfavorable cytogenetic aberration in AML-M2.

Nine morphologic traits, plant height, ground diameter, leaf length, leaf width, leaf area of plant, leaf fresh weight, blades, length/width ratio, plant fresh weight of Anoectochilus roxburghii from 13 different areas were determined for correlation analysis, path analysis and principal components analysis. Different source of morphological trait variation coefficient of A. roxburghii was 2.96% -12.59%, plant fresh weight was significant positively correlated with ground diameter, plant height and leaf number, and positively correlated with leaf fresh weight. Path analysis showed that plant height had the largest positive direct effect on plant fresh weight, the leaf fresh weight and blades number had indirect effects on the plant fresh weight. Through principal component analysis, morphological traits of A. roxburghii can be divided into "Determinants of high-yielding morphology" and "Determinants of leaf production". In the actual process of production and breeding of A. roxburghii, we should pay attention to plant height, leaf fresh weight, blades numbers and other traits.

The morphological index of the seedlings including the plants height, the ground diameter, the leaf amounts, the fresh weight of the whole plant and the ratio of height to diameter was measured and the principal components were analyzed so as to determine the grading index, and stepwise cluster analysis was applied for clustering analysis. Pot experiments were used to measure the indicators of plant growth and development, the yield and the quality. The results showed that the height and ground diameter were determined as the quality indicators of the seedlings grading and the standard quality grading of seedlings of Anoectochilus roxburghii was initially set up, different seeding plants influenced the plants growth and the yield. The ground diameter of the class I was larger than that of the class II and III, so as the yield. The seedling grading had no obvious effect on the internal quality of medicinal materials. The results of the study provide the basis for standard cultivation of A. roxburghii.

OBJECTIVETo measure the serum level of secretory type II phospholipase A2 (sPLA2) in patients with coronary heart disease and investigate the possible relationship with IL-8 and LPA.

METHODSA total of 110 patients with acute coronary syndrome (ACS), 63 patients with stable coronary heart disease (SCHD) group and 89 non-CHD control patients were studied. Serum levels of sPLA2, IL-8, LPA and hs-CRP were measured and the correlation among these parameters was observed.

RESULTSThe levels of serum sPLA2 [(68 +/- 17) U/ml], IL-8 [(182 +/- 80) pg/ml] and LPA [(2.85 +/- 0.36) micromol/L] were significantly higher in CHD patients than those in controls [sPLA2: (55 +/- 12) U/ml; IL-8: (119 +/- 33) pg/ml; LPA: (2.34 +/- 0.36) micromol/L, all P < 0.01], and sPLA2 and IL-8 were also significantly higher in ACS patients [sPLA2: (71 +/- 18) U/ml; IL-8: (195 +/- 78) pg/ml] than those in SCHD patients [sPLA2: (63 +/- 12) U/ml; IL-8: (159 +/- 79) pg/ml, both P < 0.01]. Serum sPLA2 level was positively correlated with hs-CRP, IL-8 and LPA (r = 0.203, P = 0.007; r = 0.658, P < 0.01; r = 0.231, P = 0.005, respectively). The relative risk of having CHD is 6.248 (P < 0.01) with the sPLA2 level above 63.75 U/ml.

CONCLUSIONElevated serum sPLA2 level is a risk factor for CHD.

OBJECTIVETo study the pharmacokinetic of 10-Hydroxycamptothecin HCPT by intraperitoneal administration.

METHODSix dogs were given HCPT by intraperitoneal perfusion: HCPT 2 mg x kg(-1), dissolved in 300 mL NS. During the course of experiments, peritoneal fluids and blood were sampled using a standardized protocol. The concentration of HCPT in all samples was determined by high performance liquid chromatography (HPLC).

RESULTThe area under the curve (AUC) of peritoneal fluids was significantly highly as compared to the AUC of femoral vein and portal vein (P < 0.001).

CONCLUSIONThese experiments demonstrate that intraperitoneal chemotherapy has significant effect on the pharmacokinetics of IP route of HCPT administration. This method should be a more reasonable chemotherapy for the prevention of recurrence and liver metastasis of gastric cancer, colon cancer and ovary cancer after radical resection.

OBJECTIVETo study the growth way of parotid pleomorphic adenoma and the relative factors.

METHODSThe histological slides of 97 cases of the primary parotid pleomorphic adenoma were examined for the state of intra-capsule infiltration and extra-infiltration. The relative relationships between the infiltration state and the histological type, relative amount of various components, size and course of the tumor were analysed to investigate the growth way and relative factors.

RESULTS1. There were more chances to develop infiltration of tumor in which the major content was epithelium. The tumor was severer with the increasing of epithelium, and decreasing of mucous content and elongation of course of the disease. 2. The limitation of the extra-envelop infiltration and budding was 0.085 - 0.210 mm, so, the boundary of partial parotidectomy should be away from the 1 cm envelop.

CONCLUSIONThe growth way of parotid pleomorphic adenoma is related to the histological types and characters, relative amount of various components and the course of the tumor.

Objective To study the doses and methods of F1 antigen(F1Ag) to immune Balb/c mice during the establishment of hybridoma cell strains. Secreting McAbs against F1Ag of Yersinia pestis. Methods Balb/c mice of seven to nine weeks old were randomly divided into six groups. The first four groups were 150, 100, 50 and 25 μg F1Ag inoculated group, having multipoint hypodermic inoculation of F1Ag of 150, 100, 50 and 25 μg followed by multipoint hypodermic inoculation of F1Ag of 100 μg for a second time and then intraperitoneal injection of 100 μg. Next, hypodermically inoculated group received F1Ag of 100 μg for three times in multiple points. Finally, the intraperitoneal injection group was intraperitoneally inoculated with F1Ag of 100 μg for three times. Emulsification liquid of F1Ag + Complete Frednd's adjuvant(CFA) of equivalence was used in the first inoculation, emulsification liquid of F1Ag + Incomplete Frednd's adjuvant(IFA) balanced mix in the second, F1Ag liquid in the third. One week afterwards, tail blood of the mice was collected to test antibody titers of anti-F1Ag by double antigens sandwich enzyme linked immunosorbent assay (DAgS-ELISA) and trace indirect hemagglutination assay(IHA). Results The levels of antibody of anti-F1Ag in 150,100,50 and 25 μg groups had statistics difference (DAgS-ELISA method: G = 12 173.87,13 440.37,15 024.19 and 4466.72, F= 3.11, P< 0.05;IHA: G = 19 972.32,18 089.40,23 170.47 and 4871.08, F = 4.11, P < 0.05). Immune effect of the 3 groups of 150, 100 and 50 μg was almost the same (P> 0.05), and excelled as compared with that in 25 μg group with statistics difference(DAgS-ELISA method: t = 2.18,2.39,2.73, P < 0.05;IHA: t = 2.54,2.73,3.13, P< 0.05). The titer of F1 antibody had an increasing trend from the 100 μg group to hypodermic group and intraperitoneal injection groups, but without statistics difference (DAgS-ELISA method: G = 8933.44, 9986.16, 13 440.37;IHA: G = 13 777.25,16 384.00, 18 089.40, F = 0.66,0.25, all P > 0.05). Conclusions Hyodermical inoculation of F1Ag with the first dose of 50 μg in multiple points for mouse is appropriate, and a strengthening dose of 100 μg in an intraperitoneal injection may shorten the immune period.
