OBJECTIVEThe purpose of this study was to investigate the relationship between the results of flowcytometry analyses of different clinical stage, location, pathologic grade and cell origin of oral and maxillofacial non-Hodgkin's lymphoma (NHL), and the diagnostic value of flowcytometry analysis in lymphoma.

METHODThis study analyzed 50 oral and maxillofacial NHL cases and 10 reactive lymph nodes (formalin fixed and paraffin embedded) by flowcytometry (FCM).

RESULTSReactive lymph nodes were all diploid. The diploid rate of NHL was 54%, and aneuploidy rate was 46%. There was statistically significant difference between reactive lymph nodes and NHL in the DNA ploidy status and cell cycle data (SPF, CV, S + G2/M, DI). The S phase fraction (SPF) and S + G2/M had close relationship with the grade of NHL. SPF value and DNA ploidy status had no obvious relationship with the prognosis.

CONCLUSIONThe results suggested that the FCM had diagnostic value in NHL, especially when the morphological diagnosis was difficult. Although the cell cycle data had no prognostic value, SPF and SPF + G2/M can show the proliferative status of NHL, which can help clinical doctor select therapeutic method.

OBJECTIVEThe aim of this study is to study genotype, transmission, clinical and pathological characteristics, and prognosis of oral condyloma acuminate (CA) in children.

METHODSThe authors retrospected the clinical characteristics and slices of HE staining of six cases which have been diagnosed as oral CA and, performed inmunohistochemistry (IHC) and in situ hybridization (ISH) analysis to detect the DNA of human papilloma virus in 5 cases.

RESULTSOral CA often happened in the hard or soft plates of children of two-year-old. Most of them came from the families had been infected by human papilloma virus (HPV). Histological examination demonstrated that koilocytes were common in the upper spinous and corneal layers. HPV was detected in all cases. HPV16/18-E6 antigen was positive in 4 of 5 cases examined. The result of ISH only show one case was HPV6- and HPV11-positive, and the other case was HPV-positive, but HPV could not be detected when recurring.

CONCLUSIONThe pathogen leading to oral condyloma acuminate (CA) and the transmission way of children may be different from that of adults.

OBJECTIVEThe aim of this study was to investigate the association between clinical and pathological characteristics of primary oral mucosal malignant melanoma and the prognosis of this disease.

METHODSClinical and pathological characters of 73 cases primary oral mucosal malignant melanoma were investigated. The association between risk factors, such as black macule, lymph node metastases, invasive depth, clinic stages, pathologic types, and prognosis was analyzed using Kaplan-Meier survival analysis and Log rank test.

RESULTSThe age of the patients ranged from 24 to 80 years (Median age, 50). Among the patients, 43 were males and 30 were females. The most common locations of the tumor were palate and gingiva. The clinic stages of these patients were as the following: Stage I (46/73), Stage II (24/73), Stage III (3/73). The most common pathological type was nodular (44/73), followed by lentiginose malignant melanoma (15/73) and superficial spreading (1/73). According to the configuration of tumor cells, the most common type was the mixed cell type (37/73), followed by the epitheloid cell type (27/73) and the spindle cell type (9/73). Among the 73 patients, 43 were followed up, the 3-year and 5-year survival rates were 19.86% and 11.91% respectively. Black macule, lymph node metastases, invasive depth, clinic stages, pathologic types and therapeutic methods were significantly associated with the prognosis (P < 0.05).

CONCLUSIONThe prognosis of the primary oral mucosal malignant melanoma is associated with black macule, lymph node metastases, invasive depth, clinic stages, pathologic types, and therapeutic methods.

OBJECTIVE To ex plore the economic value of medication therapeutical management （MTM）service for patients with stable coronary disease. METHODS Totally 140 patients with stable coronary disease were divided into a control group and a intervention group ，70 cases in each group. Patients in control group were received routine medical services ，and patients in intervention group additionally received standardized MTM services on this basis. Medication complication ，satisfaction degree ， safety indexes and efficacy indexes were compared between 2 groups. From the perspective of the whole society ，the economic value of MTM service for patients with stable coronary disease were evaluated by pharmacists using cost minimization analysis. RESULTS A total of 15 patients did not complete the study ，including 5 cases in intervention group and 10 cases in control group ； there was no death endpoint during the follow-up period. MMAS- 8 score，satisfaction score of drug communication dimension and score of overall satisfactionin of intervention group were obviously higher than control group （P＜0.01）. There was no significant difference in blood pressure standard rate ，blood lipid standard rate ，the incidence of adverse drug reaction ，and the incidence of acute coronary events between 2 groups（P＞0.05）. The total cost of intervention group was lower than that of control group （P＜ 0.01）；the results of sensitivity analysis were consistent with those of cost minimization analysis. CONCLUSIONS Pharmacists implement MTM service for patients with stable coronary disease can reduce total cost ，save medical resources and has economic advantages.
