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 evaluate the effect of implementation of prevention from mother-to-child transmission of syphilis in Minhang district of Shanghai from 2013 to 2019.Methods:The data of 284 pregnant women with syphilis infection diagnosed by 6 midwifery medical institutions in Minhang District from January 2013 to December 2019, were collected from the database of national management information system for prevention of mother to child transmission of AIDS, syphilis and hepatitis B. Among them there were 1 case of spontaneous abortion, 4 cases of ectopic pregnancy, 42 cases of lost follow-up; the remaining 237 parturients were included in this study. The Implementation Program of prevention of mother-to-child transmission of AIDS, syphilis and hepatitis B (2015 edition) has been implemented since 2015 in Minhang district. The maternal and neonatal outcomes between the period of 2013-2015 (before program implemented, 123 cases) and the period of 2016-2019 (after program implemented, 114 cases) were compared. Results:Between 2013 and 2019, the syphilis detection rate of pregnant women remained 100.00% (100 761/100 761). The detection rates during pregnancy before and after program implementation were 95.92% (51 855/54 288) and 98.87% (45 949/46 473); the prevalence rate of syphilis was 2.93‰ (159/54 288) and 2.69‰ (125/46 473), respectively. The rate of anti-syphilis treatment was 62.60% (77/123) and 85.96% (98/114), the standard treatment rate was 20.33% (25/123) and 49.12% (56/114), the neonatal preventive treatment proportion/rate was 1/12 and 94.74% (72/76). The detection rate during pregnancy, anti-syphilis treatment rate, standardized treatment rate and neonatal preventive treatment rate after program implementation were significantly higher than those of before implementation (χ 2=988.88, 16.72, 21.81, 54.72, all P<0.01). The rate of non- Treponema pallidum antigen titer ≥ 1∶8 was 36.89% (38/103) and 17.48% (18/103), respectively in two periods; the incidence of neonatal adverse health problems was 21.49% (26/121) and 6.03% (7/116); congenital syphilis report incidence rate was 152.12/100 000 live births (83/54 562) and 23.46/100 000 live births (11/46 890), respectively. All these indicators showed a significant reduction (χ 2=9.81, 11.80, 45.10, all P<0.01). The treatment rate of pregnant women with previously diagnosed syphilis infection was 63.27% (62/98), which was lower than that of those with initially diagnosed (81.29%, 113/139) ( cOR=2.52, 95 %CI: 1.40-4.56, χ 2=9.672, P<0.01). Among whose with lost follow-up, the floating pregnant women accounted for 92.86% (39/42), 57.14% (24/42) of whom were unable to contact and 30.95% (13/42) refused to be followed up. Conclusions:After the implementation of prevention program, the rates of detection and diagnosis, standardized treatment, neonatal preventive treatment, as well as the maternal and neonatal outcomes of pregnant women with syphilis infection have been significantly improved in Minhang district of Shanghai.

OBJECTIVETo explore the effect of the autoantibody against the β3-adrenoceptor on rats with experimental heart failure.
METHODThe peptide corresponding to the sequence of β3 adrenoceptor was synthesized to actively immunize the rats, ELISA was used to detect the serum level of autoantibody against the β3-adrenoceptor (β3AA). Total IgGs were extracted from the serum containing β3AA in immunized rats. Aortic banding surgery was used to establish the heart failure model in male Wistar rats and rats were divided into the sham group (n = 8), heart failure group(n = 8),β3AA-immunized heart failure group (HF+β3AA, n = 8) and corresponding negative IgG-immunized heart failure group (HF+ IgG, n = 8).In 6 weeks and 8 weeks after aortic banding surgery, the serum levels of NT-pro brain natriuretic peptide (NT-proBNP) were assayed with ELISA assay and cardiac function was assessed by echocardiography.
RESULTSβ3AA was used to immunize rat with heart failure, the serum level of β3AA was stable at 50 days post immunization. At 8 weeks after aortic banding surgery, heart failure group showed significantly increased LVEDD [(6.92 ± 0.22) mm vs.(5.62 ± 0.19) mm, P < 0.001], LVESD [(4.63 ± 0.23) mm vs.(3.50 ± 0.20) mm, P < 0.01] and IVS [(2.44 ± 0.06) mm vs.(2.28 ± 0.05) mm, P < 0.05], and decreased LVEF[(62.07 ± 3.99)% vs.(79.63 ± 3.02)%, P < 0.01] and LVFS [(31.46 ± 3.22)% vs.(43.65 ± 2.68) %, P < 0.05] compared with the sham group.HF+β3AA IgG group showed decreased LVEDD [(6.07 ± 0.30) mm vs.(6.92 ± 0.24) mm, P < 0.05] and LVESD [(3.92 ± 0.22) mm vs.(4.68 ± 0.23) mm, P < 0.05], and higher LVEF [(70.29 ± 1.78)% vs.(61.95 ± 3.03)%, P < 0.05] and LVFS [(38.08 ± 2.32)% vs.(30.50 ± 1.82)%, P < 0.05] compared to the HF+ IgG group.In addition, compared with the HF+ IgG group, HF+β3AA IgG group showed decreased serum levels of NT-proBNP [(196.43 ± 6.56) pg/ml vs.(242.13 ± 7.86) pg/ml, P < 0.01].
CONCLUSIONOur results demonstrate that β3AA can improve cardiac function and reduce the serum levels of NT-proBNP in rat with heart failure.
