Objective The purpose of this paper is to understand the advantages and disadvantages of the bone marrow smears and bone marrow biopsy in multiple myeloma diagnosis and efficacy judgment,explicit the value of bone marrow smears and bone marrow biopsy synchronous check in the diagnosis and treatment observation of multiple myeloma.Methods With two step-suction two biopsy specimens assay,obtained specimens of bone marrow smears and bone marrow biopsy,retrospective-ly analysed results of 283 multiple myeloma patients bone marrow smear and biopsy,and made a comparative study on the degree of bone marrow hyperplasia,myeloma cell morphology,the degree of tumor cell infiltration,proliferation pattern,bone marrow stromal pathological changes,and fibrosis cases.Results The degree of proliferation of bone marrow biopsy sections and infiltration of plasma cells was significantly higher than that of bone marrow smears,statistically there was a significant difference (P <0.01).Multiple myeloma diagnostic sensitivity by bone marrow biopsy sections was significantly higher than by the bone marrow smears,the difference was statistically significant (P < 0.05).Plasma cells in bone marrow biopsy tumor proliferation modes:clusterpiece nodular type 33 cases (11.66%),interstitial-type 86 cases (30.39%),among nodular interstitial type 112 cases (39.58%),diffuse cypriot real 52 cases (18.37%).Plasma cells in bone marrow smears tumor morphology:small mature plasma cell type 77 cases (27.21%),immature plasma cell type 148 cases (52.30%),protoplas-mic cell type 36 cases (12.72%),reticular plasma cell type 22 cases (7.77%).Conclusion Marrow biopsy can accurately reflect the degree of bone marrow hyperplasia,plasma cell tumor proliferation mode and infiltration degree,myelofibrosis sit-uation;bone marrow smears Wright-Giemsa staining,plasma cell tumor morphology was clear,typicalfeatured,and easily i-dentifiable.Bone marrow smear and biopsy synchronous check can improve the sensitivity and accuracy for multiple myeloma diagnosis,which has very important significance for multiple myeloma diagnosis and treatment observation.

Objective To explore the abnormal karyotype characteristics of myelodysplastic syndrome (MDS)patients and their correlation with clinical prognosis.Methods Analyzed the karyotypes of 281 MDS patients by use of G-banding tech-nique.Results Through analysis of the karyotypes of 281 MDS patients,found that the percentage of abnormal karyotypes was 48.75% (137/281),among 137 patients with abnormal karyotypes,43.07% (59 cases)presented with numerical aber-ration,31.39% (43 cases)with structural aberration,and 25.54% (35 cases)with both numerical and structural abnormali-ties.As for MDS subtypes,the occurrence rate of abnormal karyotype was 63.41% (26/41)in RAEB-2,58.73% (37/63)in RAEB-1,39.2% (49/125)in RCMD,15.38% (2/13)in RAS and 22.58% (7/31)in RA.The rates of abnormal karyotype in RAEB-1 and RAEB-2 were significantly higher than that in RA and RAS(P<0.01),and in RCMD (P <0.05).The fre-quent abnormal karyotypes were as follows:+8,-7/7q-,-20/20q-,complex karyotypes chromosomal translocation,i(17),-Y and +21.The follow-up study of 159 MDS patients indicated that the median survival time was 39 months for 68 patients with normal karyotypes and 21 months for 91 patients with abnormal karyotypes,the former was significantly prolonged than the latter (P < 0.05).As far as the leukemia transition rate was concerned,the patients with aberrant karyotypes (35.5%)were significantly higher than that with normal karyotypes (10.3%)(P < 0.01),among them,the cases with complex karyotypes and-7/7q-more easily transit into leukemia.Conclusion MDS was one kind of clonal hematological ma-lignancy with high heterogeneity.Chromosomal karyotype test plays an important role in the correct diagnosis,typing and prognosis evaluation of MDS.

Objective To explore the correlation between psychological health service demand and loneliness and anxiety depression in rural left-behind women.Methods 260 left-behind wo nen in Hebei province were surveyed by psychological health service demand scale,UCLA loneliness scale,trait anxiety scale and the center for epidemiologic studies depression scale (CES-D).Results There were statistically significant differences between the only child and non-only child left-behind women in mental health service demand ((131.72±13.91) vs (122.94±14.76)),loneliness ((52.94±5.65) vs (49.864±5.90)) and anxiety ((50.97±6.38) vs (47.16±4.80)) (t=3.313,2.899,4.151,P＜0.01).The mental health service demand,loneliness,anxiety and depression of left-behind women were different in the age of marriage (F=6.196,9.441,5.257,4.221,all P＜0.01),husband go out time (F=2.761,27.020,4.550,2.830,all P＜0.05) and degree of farm work (F=12.142,6.403,4.115,5.366,all P＜0.001).The anxiety of left-behind women was positively correlated with service content,service demand and depression (r=0.138-0.221,P＜0.01).Depression was negatively correlated with mental health service demand and service teams (r=-0.352--0.223,P＜ 0.01).Loneliness was positively correlated with service content,anxiety and depression (r=0.177-0.262,P＜ 0.01).Multiple linear regression showed that husbands go out time (β=0.326),farm work in very heavy degree (β=-0.376) and relatively heavy degree (β=-0.281),depression (β=-0.194) had a predictive effect on mental health services.Conclusion The mental health service demand of left-behind women are affected by their age,whether the only child,the age of marriage,their husbands' go out time and the degree of heavy farm work.

Three hundred and nine patients with thyroid nodules detected by physical examination in Harrison International Peace Hospital from October 2013 to October 2017 were divided into intervention group (155 cases) and control group (154 cases). Patients in intervention group received oral levothyroxine sodium 25 g / d for 12 months and those in control group had no treatment, patients were followed up every 3 months to 12 months. After treatment, the maximum diameter and thyroid nodule volume of the intervention group were (31.87±3.84) mm and (17.32±0.94) cm3, which were significantly smaller than those of the control group [(34.01±3.72) mm and (24.25±1.21)cm3, P<0.05]. TSH in intervention group was lower than that in control group [(2.24±0.41) vs. (2.52±0.58) mIU/L, P<0.05] and free T4 (FT4) was higher than that in control group [(25.64 ± 3.85) vs. (16.39 ± 3.28) pmol/ L, P<0.05]. TC, TG and LDL?C in intervention group, were lower than those in the control group .The HDL?C level in intervention group was higher than that in control group (all P<0.05). After treatment, there were no malignant changes in the intervention group, while the malignant change rate in control group was 2.6％ (4/154). It is suggested that levothyroxine treatment can reduce TSH level in patients with benign thyroid nodules, inhibit the growth of thyroid nodules.

Objective:To explor the effects of mentalization-based family therapy (MBFT) on the emotions of anxiety and depression, reflective functions, and related brain regions of adolescents with depression.Methods:Thirty-two adolescent patients with depression were selected in Beijing Huilongguan Hospital.Among them, fifteen patients treated with conventional drugs were defined as the control group, the other seventeen patients served as the observation group.On the basis of routine drug treatment, patients in the observation group were treated with 1.5 h MBFT once a week, for a total of 3 months.Among them, 10 patients underwent resting functional magnetic resonance imaging(rs-fMRI) scans before and after the intervention.SPSS 23.0 was used for statistical analysis of scale evaluation data by using chi-square test and repeated-measure analysis of variance, and pairwise Pearson correlation was used to construct a brain network matrix for the MRI results.The patient's brain network matrix was put into Gretna to calculate, and then use repeated measures analysis of variance and t test for judgment. Results:(1)Repeated measurement analysis of variance showed, over time and group, before and after intervention, the group×time interactions of patients' reflective function, anxiety, depression were statistically significant ( F=5.113, 9.350, 5.264, all P<0.05). Further simple effect analysis showed, in the observation group, there were statistically significant differences in patients' anxiety ((55.09±14.35) vs (30.58±3.62)), depression ((61.58±16.81) vs (31.00±3.48)) before and after intervention (all P<0.01). There was no significant difference in reflective function ((8.71±0.51) vs (8.87±0.50) ) in the observation group before and after intervention( P> 0.05). The reflective function((8.92±0.33) vs (8.73±0.35)) and anxiety((50.67±13.88) vs (45.78±12.89)) scores of the control group were not statistically significant different before and after intervention(all P>0.05), and the depression scores of the control group before and after inter-vention((69.33±9.11) vs (50.94±7.99)) were statistically significant different( P<0.01). (2)rs-fMRI showed that, using the posterior parietal lobe and the medial prefrontal lobe as seed points, the group×time interactions with right inferior frontal gyrus, right fusiform gyrus, right superior temporal gyrus, left middle temporal gyrus and right superior frontal gyrus were statistically significant ( F=29.56, 20.63, 8.69, 9.49, 8.62, all P<0.05). The further simple effect analysis showed in the observation group, the pre-test was less than the post-test, and the difference was statistically significant( P<0.05). In the control group, there were not statistically significant differences in the functional connection strength before and after the test(all P>0.05). (3)The brain network analysis of 264 regions of interest (ROIs) in the whole brain showed that the number of modules in the observation group was less than that in the control group, and the difference was statistically significant ( t=-2.64, P=0.046). Conclusion:MBFT can improve the anxiety and depression of adolescent patients with depression.It enhances the functional link between mentalization related brain regions and the whole brain, and enhances the activity of the whole brain link to become more integrated.
