Objective:To survey the status of anxiety/depression and lifestyle among junior high school students and explore their relation to put preference for psychological health education.Methods:Totally 1597 junior high school students aged 10 to 17 years in Shang Haicity were surveyed.The Generalized Anxiety Disorder-7 (GAD-7),Patient Health Questiormaire-9 items (PHQ-9) and Chinese Adolescent Lifestyle Scale (CALS),were used to assess anxious emotion,depressive emotion and lifestyle.Results:The rates of anxious emotion and depressive emotion were 16.4％ and 17.2％ respectively among students.Scores of GAD-7 and PHQ-9 were negatively correlated with all factor scores of CALS including eating habits,sleep status,health habits,learning habits,exercise,entertainment activities,interpersonal relationships,coping style and life satisfaction (-0.57 ≤ r ≤-0.15,Ps ＜ 0.01).Multivariate stepwise regression analysis showed that the sleep status factor scores,life satisfaction and exercise factor scores of CALS could negatively predict scores of GAD-7 (β3 =-0.17,-0.15,-0.05;Ps ＜ 0.05) and health habits positively predict scores of GAD-7 (β3 =0.08,P ＜0.001).Sleep status factor scores,life satisfaction factor scores and eating habits factor scores could negatively predict scores of PHQ-9 (β3 =-0.21,-0.16,-0.06;Ps ＜ 0.05).Conclusion:It suggests that the junior high school students'depression and anxiety are related to their lifestyle.The emotion of depression and anxiety of students may be predicted by some factors in the lifestyle.

Objective To analyze the treatment efficacy and safety of a modified GMALL protocol for adult acute lymphoblastic leukemia (ALL). Methods Data of 37 patients with newly diagnosed adult ALL treated with a modified GMALL protocol from January 2005 to December 2009 were retrospectively analyzed,and compared with that of 44 patients treated with an in-house conventional protocol at the same period.Results The complete remission (CR) rate was 89.2 %(33/37) treated with modified GMALL protocol. The cumulative overall survival (OS) rates at 1 year, 2 years, 3 years and 4 years were 77.5 %, 48.0 %, 40.0 %and 40.0 %, respectively. The main adverse events were grade 3 or grade 4 hematological toxicities and infections which were easily managed, and the treatment-related mortality rate was low. The OS of modified GMALL protocol was superior to that of the conventional protocol. Conclusion The modified GMALL protocol has a satisfying effect and the adverse events can be tolerated for adult ALL, so its clinical application can be encouraged.

Objective To assess the optimal visiualization capacity of brachial plexus with three-dimensional nerve-sheath signal increased with inked rest-tissue rapid acquisition of relaxation imaging (3D SHINKEI), exploring the feasibility of preliminary diagnostic value on brachial plexus diseases. Methods MRI scans were performed on 24 healthy volunteers with no history of brachial plexus injury, and 46 patients whose outcomes of lesions had been verified as post-ganglionic brachial plexus injuries by surgery or clinical follows-up . The scan series consist 3D SHINKEI, STIR in the coronal plane as well as DW-MRN in the axial plane using a 3.0 T MR system. The source and post-processed images of 3D SHINKEI and DW-MRN were scored according to the optimal visibility on brachial plexus, in the meanwhile, contrast-to-noise ratio of the original images in the 3D SHINKEI and STIR sequences were calculated separately. Two radiologists blindly compared the detection rate of positive brachial plexus injuries between 3D SHINKEI and STIR in 46 patients. And then analyze the outcomes by means of Kappa test, Mann-Whitney test , independent sample t test, and Chi-square test. Results Post-ganglionic brachial plexus showed high intensity in the 3D SHINKEI sequence. In the 24 healthy volunteers, the scores by the two radiologists were 3.6 ± 0.6, 3.5 ± 0.6, 3.0 ± 0.2, 2.9 ± 0.1, respectively. There was statistical difference between the two sequences (Z=2.667,P=0.008,P<0.05). And the Kappa was 0.8 and 0.6 with favorable consistency. The CNR of 3D SHINKEI and STIR were 0.61 ± 0.07, 0.42 ± 0.03 (t=12.78, P=0.001, P<0.05). The positive detection rates of post-ganglionic brachial plexus injuries on 3D SKINKEI and STIR were, 78.3%, 52.2%(χ2=9.421, P<0.05). Conclusions 3D SHINKEI sequence demonstrates robust visibility consistently and can clearly display the structures and signals of post-ganglionic abnormality, compared with DW-MRN and STIR. This technique can be helpful to provide more complementary information to further confirm the diagnosis of brachial plexus injuries.

Objective To study the correlation between ABO blood groups and leukemia and lymphoma, and the regional difference. Methods A case-control study had been conducted. The distribution of ABO blood groups was investigated in leukemia patients, lymphoma patients and controls, respectively. Also ABO blood group distribution of leukemia and lymphoma were compared in different areas. Results The distribution of ABO blood groups between patients with acute non-lymphocytic leukemia, acute lymphocytic leukemia, non-Hodgkin lymphoma and health person was significantly different (χ2 = 21.23, χ2 =8.36, χ2 = 9.39,P <0.05). There were regional differences in the ABO blood groups distribution of leukemia and lymphoma,especially ABO blood groups were significantly different in leukemia patients (χ2 = 50.65, P <0.05).Conclusion ABO blood groups might be a genetic susceptible factor of leukemia and lymphoma, but the geography might be a major influential factor.

Objective: To investigate the effect of mitoxantrone (MIT) on calreticulin (CRT) expression in B16 cells, and to observe the immune effect of B16-membrane antigen vaccine highly expressing CRT on B16 tumor-bearing mice. Methods: The expression of CRT on membrane of B16 cells was detected by immunofluorescence after treatment with different concentrations of MIT. B16-implanted mouse model was established, and the growth of B16-implanted tumors and CRT expression in B16-implanted tumor tissues were observed after treatment with different concentrations of MIT. Membrane antigen vaccines from both normal B16 cells and MIT-treated B16 cells were prepared, and mice were immunized before B16 cell implantation. The infiltration of immune cells into B16 tumor tissues and the ratios of CD4~+ and CD8~+ T cells in the spleen of B16 tumor-bearing mice were examined by immunohistochemistry and flow cytometry, respectively. Results: Flow cytometry results showed that MIT dose-dependently increased CRT expression on B16 cell membrane, with CRT expression in control and high dosage MIT groups being (29.40±3.57)% and (72.20±2.94)% (P<0.05), respectively. MIT also increased CRT expression in B16 tumor tissues, with those in the control and high dosage MIT groups being 3.21±1.37 and 9.17±1.06 (P<0.05), respectively. MIT effectively inhibited the growth of B16 tumors (P<0.05). Compared with normal B16 cell membrane antigen vaccine, the vaccine highly expressing CRT increased the numbers of DCs and T cells in B16 tumors tissues and the ratios of CD4~+ and CD8(+) T cells in the spleen (P<0.05). Conclusion: MIT can increase CRT expression on membrane of B16 cells. B16-membrane antigen vaccine highly expressing CRT can enhance the infiltration of DCs and T cells in melanoma, thus improving the immune effect of B16-membrane antigen vaccine.

Objective:To explore the clinical characteristics, diagnosis and treatment of acute leukemia patients during pregnancy.Methods:The clinical data of 16 cases with acute leukemia during pregnancy from January 2009 to December 2018 in the First Affiliated Hospital of USTC were retrospectively analyzed. The diagnosis and treatment regimens, pregnancy outcome, the early fetus and survival status of patients were also analyzed.Results:All 16 leukemia cases were confirmedly diagnosed and classified by bone marrow puncture, including 13 cases of acute myeloid leukemia (5 cases of non-acute promyelocytic leukemia and 8 cases of acute promyelocytic leukemia) and 3 cases of acute lymphoblastic leukemia. At the time of confirmed diagnosis, 6 patients were in first trimester, 6 cases in second trimester and 4 cases in late trimester. As for pregnancy outcome, 1 patient had natural birthing, 5 patients underwent cesarean operation, 9 patients underwent artificial abortion and 1 patient had spontaneous abortion. Chemotherapy was performed in 15 patients during pregnancy, 11 patients received chemotherapy for treatment of primary disease after pregnancy, 3 patients died during the treatment. During the follow-up of 13 cases, 8 patients survived and 5 patients lost follow-up.Conclusions:Early diagnosis of acute leukemia during pregnancy is very important. Bone marrow puncture should be performed timely to make clear diagnosis when blood routine result is abnormal during antenatal care. Multidisciplinary consultation should be initiated in time, and the best treatment plan should be worked out to guard against serious complications during pregnancy.

ObjectiveTo explore the genetic abnormalities of multiple myeloma (MM)patients by fluorescence in situ hybridization (FISH).MethodsWith the application of FISH,sequence specific DNA probes (IGH,DI3S319/p53 and 1q21/RB1) were applied to detect 14q32 rearrangement,del(13q14),del (17p13)and gain of lq21.Forty-four MM patients were enrolled in this study.ResultsThirty-two cases (72.7 ％) detected by FISH had genetic abnormality in 44 cases,lq21 amplification was observed in 11 cases (25.0 ％),while RB1 deletion in 17 cases (38.6 ％),D13S319 deletion in 16 cases (36.4 ％),p53 deletion in 6 cases(13.6 ％)and 14q32 translocation in 19 cases(43.2 ％).The patients with one abnormality was detected in 10 cases(22.7 ％),two abnormalities in 11 cases(25.0 ％),three abnormalities in 8 cases (18.2 ％),4 abnormalities in 3 cases(6.8 ％).28 were found to undergo split-phase by conventional cytogenetic in 44 patients.The patients with genetic abnormalities detected by conventional G-banding was 2 cases (7.14 ％),the difference with that in FISH was significant (P ＜0.05).Genetic abnormalities compared with clinical parameters showed that β2-MG in IGH gene abnormal patients were significantly higher than those without such abnormalities (P ＜0.05).Patients with bone marrow plasma cells of lq21 amplification were higher than those with normal karotypes(P ＜0.05),CRE was significantly higher among lq21 amplification and p53 deletion patients (P ＜0.05),CRP was significantly higher among p53 deletion patients (P ＜0.05).No significant difference was oberserved in relationship of the chromosome aberration and age,the chromosome aberration and stage.ConclusionThe most common genetic abnormalities in MM is IGH rearrangement and absence of RB1 and D13S319,followed by lq21 amplification,the least is p53 deletion.FISH is a rapid and sensitive technique to refine chromosome aberrations in MM.The specific detection for genomic features of MM is proved to be correlative with its clinicopathologic characteristics and the prognosis.

Objective:To evaluate the feasibility and the application values of quantitative susceptibility mapping (QSM) for the assessment of meniscal injury and in distinguishing meniscus degeneration and tears.Methods:The clinical and imaging data of 70 patients suspected of meniscus injury and scheduled for arthroscopy in Shandong Medical Imaging Research Institute, Cheeloo College of Medicine, Shandong University from November 2019 to June 2020 were analyzed retrospectively. Thirty age-and sex-matched healthy subjects were also examined as controls. All subjects received knee joint QSM and routine MR imaging. According to the results of arthroscopy, the patients was divided into meniscus degeneration and meniscus tear groups, respectively. The conventional MR was evaluated by two radiologists. The meniscus injury area was delineated on the original QSM magnitude images (the central area of the posterior corner of the lateral meniscus was selected in the healthy controls) and mapped to the corresponding QSM maps, and the magnetic susceptibility values were measured. Kruskal-Wallis H test was used to analyze the magnetic sensitivity values of meniscal degeneration, meniscal tear and healthy control groups; and Bonferroni was used to correct the pairwise comparison. ROC curve was established to evaluate the threshold and efficacy of magnetic susceptibility value in the diagnosis of meniscal tear. The results were compared with those of conventional MRI. Results:The magnetic susceptibility values of meniscus of healthy controls, meniscal degeneration and meniscal tear groups were (0.035±0.016)ppm, -0.031(-0.040,-0.005)ppm, and(-0.122±0.115)ppm, respectively, with significant difference found among the three groups (χ2=44.419, P<0.05). The magnetic susceptibility values of meniscus of healthy controls was significantly higher than those of meniscus degeneration patients and meniscus tear patients (χ2=-23.843, -48.253, P<0.05). The magnetic susceptibility values of meniscus of meniscus tear group was significant lower than those of meniscus degeneration group (χ2=-24.410, P<0.05). Taking magnetic susceptibility values of -0.062 5 ppm as threshold, the area under the ROC curve for the diagnosis of meniscal tears was 0.949, with the sensitivity as 87% and the specificity as 100%. The sensitivity and specificity of conventional MRI in the diagnosis of meniscal tears were 86.8% and 87.5%, respectively. Conclusion:QSM can quantitatively evaluate meniscus injury and can be used as an effective supplement method to conventional MRI, which is helpful to improve the diagnosis of meniscus tear.
