ABSTRACT
Objective@#To explore periodontal health knowledge and behavior among adolescents aged 12-15 years in Henan Province so as to provide scientific basis for oral health care.@*Methods@#According to the basic methods of the Fourth National Oral Health Survey, 3 786 school adolescents, aged 12-15 years, were selected from 12 middle schools in two district and two country in Henan by multi-stage stratified equal capacity random sampling. Oral examination and a questionnaire survey were performed among these students.@*Results@#The rate of periodontal health was 6.08%, the prevalence of gingival bleeding in these adolescents was 93.92%, its calculus existence was 90.99%. The rate of brushing teeth was 77.79%. However, the rate of brushing teeth twice or more per day was 17.56%, the rate of using fluoride toothpaste was 4.57%. The rate of periodontal health of adolescents who brushing teeth, using fluoride toothpaste were higher than adolescents who did not brush teeth, did not use fluoride toothpaste (χ2=10.81, 5.96, P<0.05). The recognition of oral care knowledge was 62.31%; except for "bacteria can cause dental caries", the awareness rate of other related periodontal diseases is more than 50.00%.@*Conclusion@#The status of periodontal health among adolescents aged 12-15 in Henan Province was not optimistic. Adolescents are lake of knowledge and health behavior towards periodontal health, The promotion of adolescents’s oral health education should be strengthened.
ABSTRACT
Objective:To investigate the efficacy and safety of daratumumab in relapsed and refractory multiple myeloma (RRMM).Methods:The efficacy and adverse events (AEs) of daratumumab based regimens were retrospectively analyzed in 37 patients with RRMM from Peking University People′s Hospital, Beijing Hospital and Fu Xing Hospital affiliated to Capital Medical University in China. The deadline for inclusion was December, 2019.Results:Among the 37 patients, 35 patients were available for response evaluation. The overall response rate (ORR) was 68.6%, which was better in patients receiving 16 mg/kg daratumumab than in those with fixed doses of 800 mg daratumumab [ORR: 78.3%(18/23) vs. 40.0%(4/10)]. The percentage of infusion related reactions of daratumumab was 27.0%(10/37). The most common hematological AEs were lymphocytopenia and thrombocytopenia, with the incidences of grade 3 or more severe 59.5%(22/37) and 43.2%(16/37) respectively. Pulmonary infections(37.8%, 14/37) were the most common non-hematological AEs. One patient with positive hepatitis B surface antigen (HBsAg) and two patients dependent on dialysis were safely treated with daratumumab.Conclusion:Daratumumab is highly effective in relapsed and refractory multiple myeloma. Adverse reactions are mild and well tolerable.
ABSTRACT
Objective@#To evaluate the feasibility and potential value of comprehensive geriatric assessment (CGA) in elderly (≥60 years) patients with newly diagnosed acute myeloid leukemia (AML) in China.@*Methods@#The CGA results of 83 newly diagnosed AML (non-APL) patients from 16 hospitals in Beijing and Tianjin between March 2016 and December 2017 were prospectively collected and analyzed. The clinical data, treatment and follow-up information were also collected.@*Results@#Of 83 newly diagnosed elderly AML patients, 81 patients (97.6%) completed all designated CGA assessment. The median number of impaired scales of the CGA assessment in the studied population was 2(0-6). Sixteen patients (19.3%) showed no impairments according to the geriatric assessment scales implem ented by this study. The distributions of impaired scales were as follows: impairment in ADL, 55.4%; IADL impairment, 42.2%; MNA-SF impairment, 48.2%; cognitive impairment, 15.7%; GDS impairment, 31.7%; HCT-CI impairment, 19.5%, respectively. In patients with "good" ECOG (n=46), the proportion of impairment for each CGA scale ranged from 6.5% to 37.0% and 32 patients (68.9%) had at least one impaired CGA scale. Survival analysis showed that the number of impaired scales of the CGA was significantly correlated with median overall survival (P=0.050).@*Conclusions@#CGA was a tool with feasibility for the comprehensive evaluation in elderly AML patients in China. Combined with age and ECOG, CGA may be more comprehensive in assessing patients’ physical condition.
ABSTRACT
Objective To investigate the immune status characteristics of primary ITP patients with abnor-mal auto-antibodies. Methods A total of 110 patients were enrolled in our study,who were admitted in Fu-Xing Hospital affiliated to Capital Medical University from January 2001 to July 2015.According to whether the patients have autoimmune diseases and the presence of auto-antibodies,we divided the patients into 3 groups,including the primary ITP with abnormal auto-antibodies(PITP-ANA)group,the primary ITP(PITP)group and the second-ary ITP(SITP)group.We compared the T-cell subsets,regulatory T cells,B lymphocytes,changes of immunoglob-ulin and bone marrow biopsy and cytology of patients among the three groups,retrospectively. Results The per-centage of CD3+T cells(61.72 ± 10.60)% in PITP-ANA group was lower than that in PITP group(69.57 ± 11.99)%. The percentage of CD8+T lymphocyte(24.00 ± 7.67)% was significantly lower than that of PITP group (30.59 ± 11.08)%(P<0.05).The proportion of Treg in PITP group,PITP-ANA group and SITP group were(6.12 ± 1.41)%,(7.50 ± 2.76)% and(8.49 ± 2.47)%,respectively,with statistically significant differences.The ra-tio of CD19+T cell in PITP-ANA group(25.75 ± 9.98)%was significantly higher than that in PITP group(16.16 ± 8.19)%(P < 0.01). The concentration of IgG、IgA、κ light chain and λ light chain in PITP group,PITP-ANA group and SITP group showed an upward trend and the highest level was in the SITP group,with statistically signifi-cant differences among the three groups. A variety of abnormal auto-antibodies could be found in both PITP-ANA group and SITP group. Conclusions We consider that the immune function abnormity of patients in PITP-ANA group were worse than that in PITP group,because the concentration of immunoglobulin,the percentage of B lym-phocyte and Treg ratio are higher in than those in PITP group.
ABSTRACT
Objective To investigate the effects of Gegenqinlian Decoction on the IL-1β level in the patients with chronic periodontitis.Methods Seventy patients with chronic periodontitis were divided into the observation group and control group,35 cases in each group.The control group was given the periodontal basic treatment.On the basis of the control group,the observation group was given Gegenqinlian Decoction.The probing depth,attachment level and bacterial plaque index level before and after treatment were compared between the two groups.The levels of IL-1β and IL-6 in serum and gingival crevicular fluid were measured before and after treatment in the two groups.Results The total effective rate in the observation group was 94.29%,which was significantly higher than 71.43% in the control group,the difference was statistically significant (χ2=6.437,P<0.05).After treatment,the probing depth,attachment level and bacterial plaque index in the two groups were significantly decreased (P<0.05),but which in the observation group were significantly lower than those in the control group,the difference was statistically significant (P<0.05).The levels of IL-1β and IL-6 in serum and gingival crevicular fluid after treatment in the two groups were decreased significantly (P<0.05),but which in the observation group were significantly lower than those in the control group,the difference was statistically significant (P<0.05).Conclusion Gegenqinlian decoction can significantly reduce the IL-1β level in the patients with chronic periodontitis,reduces inflammation reaction and improves the therapeutic effect.
ABSTRACT
Objective To explore the expression and clinical significance of proliferation associated antigen Ki-67 in acute myeloid leukemia (AML). Methods A total of 45 AML patients (including 36 newly diagnosed AML patients and 9 recurrent AML patients) and 20 healthy volunteers (healthy group) were enrolled from October 2012 to January 2016 in Department of Hematology in Fuxing Hospital. The expression of Ki-67 in bone marrow blast cells were detected by flow cytometry (FCM). The relation between Ki-67 level and clinical characteristics, and the prognostic significance of Ki-67 were studied. Results The positive rate of Ki-67 in newly diagnosed AML, recurrent AML patients and healthy controls were (10.38±8.41)%, (20.99± 11.49) % and (40.77±11.97) %, respectively. The positive rate of Ki-67 in newly diagnosed AML patients or recurrent AML patients were significantly lower than that in healthy controls (all P0.05). There was no significant difference of overall survival between high Ki-67 expression group and low Ki-67 expression group in newly diagnosed AML patients [(780±110) d vs. (788±118) d, P=0.927]. Conclusions The proliferation of blast cells in AML patients is lower than that in healthy controls. Detecting the level of Ki-67 may provide a reference for choosing the cell cycle specific chemotherapy drugs in clinical practice. Monitoring Ki-67 during AML process contributes to monitoring disease progression and predicting recurrence.

Methods:44 cases with PBC,41 cases with Hepatitis B cirrhosis and 110 normal people as control group were all analyzed bi-ochemical results and significance of serum 25 ( OH )-vitamin D. We Used receiver operator characteristic curve ( ROC ) to analyze serum 25(OH)-vitamin D in its diagnostic value of primary biliary cirrhosis. Results:Biochemical results of TBIL,DBIL,IBIL,GLB, AST,ALT,ALP,γ-GT were higher in PBC than that in normal people and Hepatitis B cirrhosis. While the serum 25(OH)-vitamin D of PBC was much more lower than that in normal and people and Hepatitis B cirrhosis. The difference between them were statistical difference(P<0. 05). The area under the ROC curve of PBC was 0. 926,it showed serum 25(OH)-vitamin D diagnosis for PBC had quite value. When the cut-off level of serum 25(OH)-vitamin D was 17. 275 ng/ml,the sensitivity for the diagnosis was 92. 8%,the re-spectively was 84. 1%. Conclusion:Serum 25(OH)-vitamin D diagnosis for PBC has quite value,the cut-off level of serum 25(OH)-vitamin D is 17. 275 ng/ml.
ABSTRACT
Objective To evaluate the treatment efficacy of leukocyte reduction in hyperleukocytic acute myeloid leukemia (HAML) patients with leukostasis grading score (LGS).Methods The data of 54 HAML patients were analyzed retrospectively.The relationship between LGS and leukocyte stasis symptoms or early mortality was observed, and the impact of leukapheresis on LGS was analyzed.Results Among 54 patients with HAML, there were 1 case of M1, 16 cases of M2, 10 cases of M4, 20 cases of M5 and 7 cases of unclassified AML.Based on clinical symptoms and LGS system, 3 cases were LGS 0, 15 cases LGS 1, 17 cases LGS 2, and 19 cases LGS 3.In patients with LGS ≤ 2, the rates of type Ⅰ respiratory failure, central nevers system (CNS) symptoms and early mortality caused by leukostasis were significantly lower than those in patients with LGS 3 (P ＜ 0.05).The LGS of HAML patients was reduced by leukocyte reduction therapy (P ＜ 0.000 1).The LGS of HAML patients treated by leukapheresis and low dose chemotherapy was improved significantly than that of patients treated without leukapheresis (P =0.008).Among 37 cases receiving induction chemotherapy, 20 cases reached complete remission (CR) after the first cycle of induction chemotherapy.CR rate of patients with LGS ≤ 2 was no significantly different compared with that of patients with LGS 3 (P =0.703).Conclusions LGS can be used to evaluate the degree and the improvement status of leukostasis after treatment in HAML patients.The early death often occurres in patients with high LGS.Leukapheresis combined with low-dose chemotherapy can effectively improve the LGS of HAML patients.
ABSTRACT
To explore the prevalence of hepatitis B virus (HBV) in multiple myeloma (MM) patients, as well as to compare the clinical characteristics and outcome between HBV infected and non-HBV infected patients. Methods:The serology markers of HBV were detected in 363 MM patients and 11227 cases of healthy controls through chemiluminescence. HBV-DNA was measured via real-time quantitative chain reaction. Results:Sixteen out of 363 MM patients (4.4%) were HBsAg-positive, showing significant difference with healthy controls (2.4%). No statistically significant differences were observed in terms of sex, age, type of monoclonal (M) protein, International Staging System (ISS) stage, stem cell transplantation, and risk stratification between HBsAg-positive and HBsAg-negative patients. No significant effect of HBV infection was found on the OS of MM patients. HBV reactivation was observed in two HBsAg-positive MM patients who were treated with combination chemotherapy, including bortezomib and dexamethasone. The replication of HBV could be inhibited by anti-HBV drugs. Conclusion:A higher prevalence of HBV infection was revealed in MM patients. Close monitoring of HBV replication should be conducted in MM patients with HBV infection before and during the courses of chemotherapy.

ABSTRACT
Acute myeloid leukemia (AML) originates from rare leukemia stem cells (LSC).Because these chemotherapy-resistant LSC are thought to underlie disease relapse,effective therapeutic strategies specifically targeting these cells may be beneficial.With the increasing knowledge regarding the LSC,several major directions in targeted therapies with regard to LSC are being investigated.These include targeting cell surface molecules,signal pathways,and microenvironment of LSC.Since eliminating LSC-should provide an efficient,potentially curative treatment option for leukemia patients,this article reviews the recent progress of LSC targeting in AML therapy.

ABSTRACT
Objective To analyze clinical and radiological characteristics of intracranial hemorrhage in hematological diseases to improve the recognition of them. Methods Thirty-one clinical data of intracranial hemorrhage cases with hematological diseases were reviewed. The basic diseases, clinical and radiological manifestations, and risk factors of mortality were analyzed. Results Intracranial hemorrhage usually occurred in patients with acute myeloid leukemia (AML) or idiopathic thrombocytopenic purpura (ITP),and 13 and 6 cases, respectively, in this group. Most patients presented with headache, restlessness, nausea,vomiting, conscious disturbance and no localization sign by physical examination. CT or MRI images often revealed focus of errlysis. Compared with CT scan, a higher detection rate of ICH could be realized by MRI scan. The total mortality in this group of ICH patients was 71% (22/31). Fever, white blood cell ＞5×109/L,platelet ＜50×109/L, hyperimmunoglobulinemia and disturbance of blood coagulation were risk factors for ICH of this group of patients. The mortality was higher in patients with no less than 2 risk factors[86.4 % (19/22)vs 33.3 % (3/9)] (x2 = 8.718, P = 0.003). Conclusion ICH is a serious complication for hematological patients. MRI scan is good at improving the diagnosis of ICH. It is of high risk of death in patients with no less than 2 risk factors such as fever, white blood cell higher than 5×109/L, platelet less than 50×109/L,hyperimmunoglobulinemia and disturbance of blood coagulation.
