Journal of Leukemia & Lymphoma 2009;18(8):481-483
Objective To explore the expression of the mRNA level of Fas (CD95) ligand/FasL and Fas-associated phosphatase-1/FAP-1 in acute myeloid leukemia. Methods The expression of FasL and FAP-1 were detected in 54 patients with AML and 10 normal subjects by semi-quantitative reverse transcriptase-polymerase chain reaction (RT-PCR). β-actin used as internal reference. The changes of FasL was observed after induction chemotherapy in 16 AML patients. The expression of Fas was detected in 54 patients with AML by flow cytometry. Results The mRNA levels of FasL and in 54 patients were remarkably higher(P <0.05) than the normal controls. The rates of first complete remission(CR) were significantly higher in FasL(+) (77.78 %) than in FasL(-) cases(16.67 %) (P<0.01). The FasL level declined in 10 patients with good response to therapy (P<0.01), and high level in 6 nonresponding patients with poor response (P>0.05). The mRNA levels of FAP-1 in 54 patients was remarkly higher than that of the normal control. 8/29 cases in Fas-positive group were positive for FAP-1 mRNA expression. 19/25 cases in the Fas-refractory group didn't express FAP-1 mRNA. Conclusion The expression of FasL was high in AML. The rates of complete remission were high in FasL positive cases. The FasL level declined in patients with good response to therapy. The expression of FAP-1was partly expressed in AML. The expression of FAP-1 was less in Fas positive group.

Tianjin Medical Journal 2015;(1):78-80,81
Objective To evaluate effects of two different flap designs (envelope flap and triangular flap) on complica?tions after the mandibular third molar surgery. Methods A randomized, self controlled clinical trial design was selected for 52 patients treated in the outpatient surgery of Stomatological Hospital Affiliated to Tianjin Medical University. Patients were treated with envelope flap design for lower third molar removal in one side and triangular flap on the other side. VAS scores were used to evaluate postoperative pain. The postoperative swelling was evaluated by patient`subjective index. The degree of the upper and lower incisor distance was used to evaluate trismus. Data of postoperative swelling, pain and trismus were re?corded 1, 2 and 7 days after surgery. Data of postoperative wound dehiscence, bleeding situation and alveolitis were also re?corded and compared between two groups. Results There were no significant differences in postoperative pain after 1, 2 and 7 days between two flap designs (P>0.05). After 1 and 2 days there was more severe facial swelling in triangular flap group than that of envelope flap group (Z=2.005, Z=2.017, P<0.05). There was more limited mouth opening after 1 and 2 days in triangular flap group than that of envelope flap group (t=2.578, t=2.410, P<0.05), but on the seventh day there was no significant difference in the severity of facial swelling and trismus between two groups (P>0.05). There were no signifi?cant differences in postoperative pain, alveolitis, bleeding and wound dehiscence between two groups (P > 0.05). Conclu?sion The envelope flap is more conductive to the early recovery in patients after surgery, but in the long term there is no ob?vious difference between the two flap designs.

Methods In this study, HIV/AIDS patients treated in Hainan Province until 2022 from the antiretroviral treatment were selected from the antiviral treatment submodule of the China Disease Prevention and Control Information System. According to the inclusion and exclusion criteria, a total of 3 150 HIV/AIDS patients were enrolled. Logistic regression analysis was used to analyze factors affecting the immunological effect of antiretroviral therapy. Results Of the 3 150 subjects, 2 906 achieved immunological success, accounting for 92.2%. The M(P25,P75) CD4+T lymphocyte count after treatment was 491 (351, 656) cells/μL. There were significant differences in the increase in CD4+ T lymphocyte counts after treatment compared to baseline across different CD4+T levels (P<0.001). Multifactorial logistic regression analysis showed that being divorced or widowed (OR=0.50, 95%CI: 0.31-0.79), age ≥60 years at the onset of treatment (OR=0.51, 95%CI: 0.29-0.90), the interval from diagnosis to treatment of 1 to <12 months (OR=0.55, 95%CI: 0.40-0.77), 12 to <60 months (OR=0.53, 95%CI: 0.34-0.80), and ≥60 months (OR=0.41, 95%CI: 0.23-0.75), as well as a CD4+ T cell count of 300 to <400 cells/μL (OR=0.36, 95%CI:0.22-0.58) and 400 to <500 cells/μL (OR=0.30, 95%CI:0.18-0.49) were negative correlation with immunological success (P<0.05). On the other hand, homosexual transmission (OR=3.46, 95%CI:2.03-5.90), heterosexual transmission (OR=1.91, 95%CI: 1.14-3.19), other/unknown transmission (OR=3.13, 95%CI: 1.50-6.53), treatment years count 2 to <4 years (OR=1.71, 95%CI: 1.13-2.58), 4 to <6 years (OR=2.86, 95%CI: 1.81-4.51), and ≥6 years (OR=2.21, 95%CI: 1.47-3.32) were positive correlation with immunological success (P<0.05). Conclusions The highly active antiretroviral therapy has achieved good immunological effects among patients with HIV/AIDS in Hainan Province. It is essential to expand HIV monitoring and detection, to diagnose and treat at an early stage, and to continue strengthening medication compliance education to further improve the immunological effects of treatment.

BACKGROUND:Endothelial progenitor cel s, known as the precursor cel s of mature endothelial cel s, have the function of neovascularization and neoendothelialization. Therefore, endothelial progenitor cel s have potential applicability in many fields. Endothelial progenitor cel s can be isolated and cultured from different resources with different methods, but the biological properties and identification of endothelial progenitor cel s stil have controversies.
OBJECTIVE:To explore the methods of isolation and culture of endothelial progenitor cel s from the human peripheral blood and to identify the biological features of endothelial progenitor cel s.
METHODS:Mononuclear cel s were isolated from the human peripheral blood using density gradient centrifugation, and the cel s were resuspended in endothelial basal medium-2 supplemented with the EGM-2-MV-SingleQuots. Then, the cel s were inoculated in human fibronectin-coated culture flasks and cultured in EBM-2MV medium. The morphology of endothelial progenitor cel s was observed. The proliferation potential and surface markers of endothelial progenitor cel s were characterized careful y. Furthermore, the functional properties such as nitric oxide release and tube formation on Matrigel were also evaluated.
RESULTS AND CONCLUSION:While adherent cel s maintained, spindle-shaped cel s formed a cel cluster after 6-7 days. Then, adherent cel s developed to endothelial progenitor cel s with a cobblestone appearance after 2-3 weeks. The endothelial progenitor cel s were confluent with an outgrowth appearance. Endothelial progenitor cel s had a higher proliferation potential compared with human aortic endothelial cel s under the same culture condition. Endothelial progenitor cel s expressed CD31, CD34, CD144 and KDR, displaying an obvious endothelial phenotype. Endothelial progenitor cel s were also found to uptake DiL-acLDL and exhibit lectin binding capability. Furthermore, endothelial progenitor cel s were able to form capil ary tubes on Matrigel and had the ability to release nitric oxide. Therefore, endothelial progenitor cel s can be obtained from the human peripheral blood by density gradient centrifugation and adherent culture. A combining method for the identification of endothelial progenitor cel s should be recommended.

Objective: To study the influence of screening dementia with mini-mental state examination (MMSE) combining with delay memory test . Methods: MMSE and delay memory test are used in screening 301 residents. The diagnosis of dementia is according to the DSM-Ⅲ-R criterion. The validity and reliability were studied when the MMSE and delay memory test were used to screen dementia alone or combined. Results: When MMSE was used to screen dementia alone, the specificity, sensitivity, false positive proportion and false negative proportion were 85.40%, 52.43%, 47.56% and 14.60% respectively. When delay memory test was used to screen dementia alone, the specificity, sensitivity, false positive proportion and false negative proportion were 74.45%, 92.07%, 7.93% and 25.55% respectively. If parallel connection of MMSE and delay memory test were used to screen dementia, the specificity, sensitivity, false positive proportion and false negative proportion were 95.62%, 49.39%, 50.61% and 4.38% respectively. If MMSE was in series with delay memory test, the specificity, sensitivity, false positive proportion and false negative proportion of screening dementia were 64.23%, 95.73%, 4.27% and 35.77% respectively. Conclusion: The parallel connection of MMSE and delay memory test can elevate sensitivity of screening dementia and decrease false negative proportion, so it is important in epidemiologic investigation. MMSE in series with delay memory test will raise specificity of screening dementia and decrease false positive proportion, so it is useful for diagnosing early dementia.
