Objective:To evaluate the effectiveness and safety of using apatinib in the treatment of refractory triple-negative advanced breast cancer. Methods:Eight cases of advanced triple-negative breast cancer patients confirmed via histopathology, who were previously treated with anthracycline, taxane, gemcitabine, capecitabine, and 500 mg/d apatinib in our hospital from July 2015 to November 2016, were retrospectively analyzed. The time of disease progress, effective rate, clinical benefits, and side effects were observed. Results:Eight patients were administrated with an average of 4 treatment cycles, and the effects were evaluated after 2 weeks. Four patients exhibited partial remission, 3 had a stable disease, and 1 had a progressive disease. The disease control rate was 87.5%, and the median progression free survival was 4.2 months. The main side effects were hand-foot syndrome (3/8), bone marrow arrest (4/8), hypertension (2/8), proteinuria (3/8), hemoptysis (1/8), nausea (2/8), and fatigue (2/8). Most of these side effects were tolerable. Conclusion:Apatinib can effectively and tolerably prolong survival time and improve the quality of life of patients with advanced triple-negative breast cancer.

OBJECTIVE: To discuss the soft palate, hard palate and mandibule for the pathogenesis and clinical treatment of patients who have obstructive sleep apnea hypopnea syndrome. METHOD: There were 52 patients with OSAHS diagnosed by the PSG and 32 cases of normal healthy volunteers in our hospital. All objects were given 128 slice spiral CT scan of the upper airway. We measured the related indexes of the soft palate, hard palate and mandible, then analysed statistical differences between them and did Pearson correlation analysis with apnea hypoventilation index (AHI), average blood oxygen saturation (MSaO2) in PSG. RESULT: Compared with the control group, the soft palate length [(37.93 ± 5.20)mm VS (33.52 ± 4.25)mm] and the distance between mandible with cervical vertebra [(75.00 ± 7.10)mm VS (69.93 ± 5.58)mm] increased significantly, but the distance of trailing edge of hard palate to inferior margin of slope significantly reduced [(42.57 ± 4.52)mm VS (45.80 ± 2.94)mm, P < 0.01] in patients with OSAHS. Each measurement associated with AHI and MSaO2 had no significant correlation (P > 0.05). CONCLUSION The soft palate, hard palate and mandibular are some of the important risk factors of OSAHS, and they also have reference value for the choice of clinical treatment operation. Preoperative CT examination can offer help in the treatment of OSAHS.

Objective To discuss the clinical diagnostic and guiding treatment value of changed positions of hyoid bonein the upper airway of patients with obstructive sleep apnea hypopnea syndrome. Methods 128-slice computed tomography was performed for 52 patients with severe OSAHS and 32normal healthy people to measure thehyoid bone in the upper airway in sober state and Muller maneuver. The correlationsbetweenthese indexes were analyzed under linear relation. Results (1)In comparison of the Muller maneuver with sober state , chinnodules and palatal plane to the hyoid in the OSAHS group were statistically higher than the healthy controlgroup (P < 0.001). (2)The distance of hyoid to chinnodules in the OSAHS group was significantlylonger and greater than that of the healthy control group (P < 0.001).(3)The distance of palatal plane to the hyoid was positively correlated with AHI , while thedistances of palatal plane andchinnodules to the hyoidwere both negatively correlated with MSaO2. Conclusion The changes ofhyoid positionare indicative for the clinical diagnosis and is helpful for the guidance of clinical treatment of OSAHS.

Objective To evaluate the value of 128-slice CT on locating the obstruction site of the upper airway in obstructive sleep apnea hypopnea syndrome (OSAHS)patients by three-dimensional reconstruction technology.Methods There were 52 patients with OSAHS diagnosed by the PSG and 32 cases of healthy volunteers in our hospital.All objects were performed 128-slice CT scan of the upper airway during awake state,and those patients’upper airways were scaned on Muller test.The airway volume of the ret-ropalatal region,retroglottal region and epiglottal region,and the total length of upper airway were measured,and statistical analysis of the each index was obtained.Results During awake state,compared with the control group,the length of upper airway in OSAHS patients increased significantly(P <0.001).Compared with the awake state,OSAHS patients’airway volume of the retropalatal region, retroglottal region and the total airway volume on the Muller test were reduced significantly(P <0.001).OSAHS patients’upper air-way length was correlated negatively to the average MSaO 2 (r=-0.33,P <0.05).Conclusion The three-dimensional reconstruc-tion of upper airway on 128-slice CT can evaluate the position and degree of the obstruction site in OSAHS patients’upper airway better,which has important significance to guide clinical treatment.

The protocorm-suspension-system of Cremastra appendiculata was founded by liquid-suspension culture. The factors to effect germination rate and seedling conversion rate of C. appendiculata synthetic seeds, such as synthetic coating materials, synthetic endosperm components, storing conditions and germination materials, etc. were studied. The result showed that the germination rate and seedling conversion rate of synthetic seeds were the highest on the MS solid-medium while using 4% sodium alginate + 2% CaCl2 + 2% chitosan as synthetic coating materials, with 1/2 MS liquid-medium + 0.2 mg x L(-1) NAA + 0.1 mg x L(-1) GA3 + 0.5 mg L(-1) BA + 0.4 mg x L(-1) penicillin + 10.0 mg x L(-1) endophyte extract +0.3% carbendazim powder + 0.2% sodium benzoate + 1.0% sucrose as synthetic endosperm. And the germination rate and seedling conversion rate of synthetic seeds could attain to 68% and 65% after 20 days storing at 4 degrees C. The germination rate and seedling conversion rate of synthetic seeds decreased to a great extent with increasing the storing temperature and prolonging storing time.

Objective: To study the development of grip strength and its relationship with body weight, height and body composition in preschool children. Methods: Data was collected from 900 children aged 3-6 years in 4 preschools in Beijing during Sept. to Oct. of 2020. A questionnaire survey (birth weight, dietary and exercise), height, weight, bioelectrical impedance analysis of body composition and dominant hand grip strength tests were conducted. Partial correlational analysis, multivariate linear regression were used for association between grip strength and body composition. Results: The grip strength gradually increased with age, from (5.2±1.7) to (9.3±2.5)kg in boys ( F=57.93, P <0.01), and from (4.3±1.6) to (7.9±2.5)kg in girls ( F=48.77, P <0.01). Grip strength in boys were significant higher than that of girls ( t=6.42, P <0.01). The grip strength increased with weight status in boys ( F=5.35, P <0.01), with highest in obese group, followed by overweight and normal weight group. After adjusted for height, weight and birth weight, as well as maternal education, food consumption during the past week, grip strength in boys was positively correlated with fat free mass, upper limb muscle mass ( r=0.11, 0.09, P <0.05), and negatively correlated with body fat mass ( r=-0.18, P <0.05). Grip strength in girls was negatively correlated with body fat mass, and positively correlated with fat free mass ( r= -0.09, 0.09, P <0.05). Grip strength varied significantly by age, fat free mass and upper muscle mass in boys ( F=66.75, P < 0.01), and by age and fat free mass in girls ( F=150.81, P <0.01). Conclusion The grip strength can partially reflect changes in fat free mass for boys and girls, it also reflect changes in upper limb muscle mass for boys. Increases in fat free mass helps grip strength improvement.

Objective:To observe and analyze the morphological characteristic of bone marrow and peripheral blood in patients diagnosed with de novo acute leukemia.Methods:From October 1, 2015 to December 31, 2021, 1151 patients aged 47 (26, 62) years, consisting of 602 males and 549 females with newly diagnosed acute leukemia in the Department of Hematology, Affiliated Hospital of Xuzhou Medical University, were collected to preform the morphological analysis in bone marrow and peripheral blood smears. Based on the comprehensive diagnosis results of morphology, immunology, cytogenetics, and molecular biology, comparison between acute myeloid leukemia (AML) and acute lymphoblastic leukemia (ALL), AML with RUNX1-RUNXITI gene, AML with CBFβ/MYH11 gene, acute promyelocytic leukemia (APL) with PML/RARA gene, AML with NPM1 gene, the rest of the AML, Ph+ALL and Ph-ALL were performed by Chi-square test along with analysis of the differences in the ratio of wood bundle cells, pseudo-Chediak-Higashi (PCH) inclusions, cytoplasmic small particles, nuclear notches, leukemia cells with cup-like changes (cup cells); as well as the differences in the micromeganuclei, early immature granulocytes, plasma cells, high eosinophils and other accompanying cells and the distribution of "grape-like" aggregation. Finally, the morphological characteristics of acute leukemia cells, the appearance and arrangement of accompanying cells were summarized.Results:Between AML and ALL, there were statistically significant differences in cytoplasmic Auer bodies[(45.5%, 0%), χ 2=211.400, P<0.01], PCH inclusion bodies[(28.9%, 0%), χ 2=114.100, P<0.01], cytoplasmic fine particles[(20.7%, 2.9%), χ 2=53.798, P<0.01], nuclear notches[(0.7%, 6.1%), χ 2=30.906, P<0.01], and goblet cells[(4.9%, 0.3%), χ 2=13.495, P<0.01], micromegakaryus [(22.4%, 0.3%), χ 2=80.398, P<0.01], plasma cells[(87.6%, 10.6%), χ 2=604.241, P<0.01], hyperacidophils[(15.3%, 1.0%), χ 2=46.116, P<0.01] showed significant differences in the "grape-like" aggregation distribution. In AML with RUNX1-RUNXITI gene, the changes of vacuoles and PCH inclusion bodies are more obvious; in AML with CBFβ/MYH11 gene, the increase of hypereosinophils is more obvious; in APL with PML/RARA gene, the increase of woodbundle is more obvious. The morphology of nuclei chromatin, nucleolus, and vacuoles were also different among the groups. Comparison between Ph+ALL and Ph-ALL showed that Ph+ALL was more prone to develop early immature granulocytes and plasma cells (all P<0.05). Conclusion:There are significant differences between AML and ALL in the characteristics of leukemia cells, the regularity of accompanying cells, and the aggregation and distribution patterns. The subtypes of AML with specific genetic abnormalities have their own characteristics in the appearance of vacuoles, PCH inclusions, hypereosinophils, woodbundle cells, and goblet cells. Ph+ALL is more prone to present early immature granulocytes and plasma cells.
