OBJECTIVETo study the edentulous patients facio-maxillary characters, and discuss the base of recording jaw relation by swallowing action.

METHODSForty-three edentulous patients were included in this study, age ranged from 57 to 70 yr, with new comfortable full dentures. Two lateral cephalograms for one patient were taken by SIRONA digital X-ray dental system, one of which was centric occlusion with full denture, another was the end position of swallowing action without denture.

RESULTSThe vertical facial dimensions of male were a little more than that of female. The ratio of lower front facial height/upper front facial height was about 6/5, angle S-N-Po was about 78 approximately 80 degrees. These data may be useful for dentists to make diagnoses if the jaw relation is right or not. Both in vertical or anterior-posterior (horizontal) dimension, the differences between two groups (two actions in one patient) were not significant. It showed that two positions of two actions were the same.

CONCLUSIONSThe SIRONA digital X-ray dental system for cephalometry was swift, and had its own characters. The way of swallowing and occluding is one of efficient methods to record the jaw relation of edentulous patients veraciously and naturally.

Aquilaria agallocha can produce fragrant agarwood used for incense, traditional medicine and other products. An efficient plant regeneration system was established via organogenesis from shoots developed from seedlings of Aquilaria agallocha. Shoots generated many buds on MS medium supplemented with 1.3 micromol/L BA (6-benzylaminopurine) in the first 7 weeks, and the buds elongated on MS medium with 1.3 micromol/L BA+0.5 micromol/L NAA (naphthaleneacetic acid) in another 7 weeks, 2.3 shoots 2 cm in length per explant were obtained within 14 weeks. Plantlets were rooted on 1/2 MS medium after being immersed in 5 micromol/L NAA for 48 h, 96.7% of the roots grew up two weeks later. All plantlets that survived acclimatization grew well in the pots.

Objective To explore the effect of aerobic exercise on patients with laryngeal cancer related fatigue status.Methods 56 cases of patients with laryngeal cancer were randomly divided into intervention group and control group, each group was 28 cases. Control group moved by themselves according to the physical condition of patients after discharge; intervention group was held regular movement according to the nurses making the exercise prescription for them, assessed the fatigue status of patients with laryngeal cancer by revised Chinese version of the Piper Fatigue Scale respectively before the intervention in patient (at discharge) and operated after two months.Results The difference of fatigue scores of the two groups before intervention (at discharge) do not reach statistical significance (P>0.05); and the fatigue scores of the two groups after intervention was significantly different (P<0.05 or P<0.01).Conclusions Aerobic exercise can eliminate or alleviate the patient's fatigue, increase quality of life.

Objective To explore the self-management action of patient suffered from mechanical heart valve post-operation. Methods 168cases of the patients suffered from the mechanical heart valve post-operation were separately divided into 86 cases as the interference group and 82 cases as control group at random. The interference group was given for the normal medical treatment and also objective self-management education but the control group used normal medical treatment and also health education. Two groups of the patients were tested by "Self-Management Action Measurement Form" separately to asseSS the self-management action and also were assessed by Chinese version of SF-36 Measurement Form for the assessment of two groups of the patients for the comparison of the patients of two groups in living quality(QOL) one year after treatment and nursing. Results The various items of assessments of interference group were higher than the comparison group in self-management action measurement form SF-36 Measurement Form with the difference of statistics meaning(P ＜0. 01) averagely for the comparison of two groups one year after the treatment and nursing. Conclusions The self-management education can help the patients to set up a good action mode and improve the patients' self-management disease ability, reduce the occurrence of the complication to improve health and reach to raise living quality of the patients suffered from mechanical heart valve post-operation for purpose.

OBJECTIVETo study the clinicopathologic features, diagnosis and differential diagnosis of splenic marginal zone B-cell lymphoma (SMZL).

METHODSThe clinical data, histologic findings and immunophenotype of 8 SMZL cases were studied. IgH gene rearrangement was performed in 1 case. Follow-up information was available in 4 patients.

RESULTSThe median age of the patients was 61.5 years (range: 36 to 75 years). The male-to-female ratio was 1.7:1. All cases presented with massive splenomegaly. Five of six cases had abnormal blood counts: neutropenia and thrombocytopenia with two of them showing anemia. After splenectomy, the blood counts in 3/3 cases returned to normal levels. Post-operative fludarabine-based chemotherapy was given to 3 patients, two of them achieved complete remission and 1 case died during the course of chemotherapy. The average survival time was 21.5 months (range: 6 to 60 months). Histologically, all of the 8 cases showed micronodular white pulp lesions. Six of them exhibited the classic biphasic appearance with central aggregates of small B cells rimmed by a peripheral zone of atypical monocytoid B cells. The remaining 2 cases had a monomorphous appearance, consisting mainly of atypical monocytoid B cells. There was infiltration of tumor cells in the red pulp, sheets in appearance in all 8 cases. Immuno-histochemical staining showed CD20-positive (8/8), IgD-positive in 2 of the 4 cases (2/4), CD5-positive in 1 of the 4 cases (1/4), 6 of the 6 cases were bcl-2-positive, cyclin D1-negative and bcl-6/CD10-negative, CD43-negative in 5 of the 6 cases (5/6). The proliferation index, as highlighted by Ki-67 immunostaining, was low (< 15%).

CONCLUSIONSSMZL is an indolent B-cell non-Hodgkin lymphoma. The main clinical manifestations are splenomegaly and abnormalities in blood counts. The main modality of treatment is splenectomy. Adjuvant fludarabine-based chemotherapy helps to achieve complete remission. In general, the prognosis of this lymphoma type is good. The lymphoma cells predominantly grow in micronodular pattern, with atypical monocytoid B cells rimming around the small B cells, which aggregates in the center. The differential diagnosis includes other small B-cell lymphomas and lymphoid hyperplasia of spleen.

OBJECTIVETo study the effect of Notoginsenoside Rgl on p38 mitogen activated protein kinase (p38MAPK) expression in pulmonary artery smooth muscle cells (PASMCs) cultured in hypoxia hypercapnia.

METHODSSD rat PASMCs was primary cultured, the cells of passage 2- 5 were divided into six groups: normoxic group (N group), hypoxia hypercapnia group (H group), dimethyl sulfoxide (DMSO) control group (HD group), Rg1 treated group (Rg low dose, Rg middle dose and Rg high dose group). Western blot was used to detect the expression of p-p38MAPK protein, and RT-PCR to determine the expression of p38MAPK mRNA.

RESULTSWestern blot and RT-PCR analysis indicated that the expression of p-p38MAPK protein and p-p38MAPK mRNA were significantly higher in HD group than those in N group (P < 0.01). Whereas, in Rg1 treated groups, the level of p-p38MAPK markedly decreased (P < 0.01) in dose-dependent manner.

CONCLUSIONNotoginsenoside Rg1 has protective effects on PASMCs under hypoxia hypercapnia condition, which may be related to inhibiting expression of p38MAPK.

OBJECTIVETo investigate the effect of tanshinone IIA on HL-60 and K562 cells apoptosis, and to assay the inhibition of the telomerase activities in the leukemia cell apoptosis induced by Tanshinone.

METHODUsing the techniques of cell culture in vitro, flow cytometry and PCR-TRAP observed the telomerase activities and apoptosis of HL-60 and K562 cells which treated by Tan IIA.

RESULT0.5 microg x mL(-1) Tan IIA could obviously inhibit HL-60 and K562 cell lines growth (P < 0.05), down-regulate c-myc, bcl-2 gene and up-regulate c-fos and p53 gene expression as well as induce leukemia cell apoptosis, the apoptotic rates of HL-60 and K562 cells were 11.8% and 21.8% respectively. The telomerase activities significant decreased, the inhibiting rates in HL60 and K562 cells were 30.8% and 50.8% respectively.

CONCLUSIONTan IIA could significantly inhibit the proliferation and telomerase activities of HL-60 and K562 cells and induce the leukemia cell apoptosis.
