Objective To explore the value of diffused optical tomography(DOT)with ultrasonography (US)in differential diagnosis of breast benign from malignant neoplasms.Methods One hundred ard twenty-three breast neoplasms from 113 patients were checked use the optical tomography image ultrasonography(OPTIMUS).The diagnosis results of the system were compared with pathological study.Two-dimensional ultrasound features in breast neoplasms were digitalizated,and HBT and SO_2 were detected by DOT.At last,synthesis diagnostic index(SDI)was obtained by both US and DOT.Statistic process was carried out in sensitivity,specificity,and the rate of accuracy respectively by US,DOT and OPTIMUS system.Results Among breast neoplasms of 123 mass studied pathologically,78 of them were benign and the rest were malignant.HBT in benign lesions(153.02±105.78)was significantly less than malignant lesions(232.95±78.22),SO_2 in benign lesions(1.0332±0.1641)was significantly elevated compared with malignant lesions(0.8794±0.1814),SDI in benign lesions(147.26±53.76)was significantly less than malignant lesions(243.98±57.27),significant differences were found between the two groups(P＜0.05).The sensitivity of differential diagnosis of breast neoplasms by the OPTIMUS system was 93.33%,the specificity was 83.33%,and the rate of accuracy was 86.99%.Conclusions OPTIMUS can improve the specificity and the rate of early diagnosis.

Objective To analyze the correlation of plasma homocysteine (Hcy) level with hemodynamic parameters and high density lipoprotein cholesterol (HDL-C) level in patients with lacunar infarction and its significance in lacunar infarction.Methods Transcranial Doppler examination was performed in 120 patients with lacunar infarction admitted to our hospital from February 2012 to March 2013 and 100 healthy controls; systolic flow velocity (SFV),distalotic flow velocity (DFV),mean flow velocity (MFV) and pulsatility index (PI) were assessed at the middle cerebral artery (MCA) and basilar artery (BA).Serum creatinine,total cholesterol,triglycerides,HDL-C,and low-densitylipoprotein cholesterol (LDL-C) levels were detected using enzymatic colorimetric method.Plasma Hcy level was measured by circulating enzymatic method.Results Blood flow velocity indexes,such as SFV,DFV,MFV and PI in the MCA of lacunar cerebral infarction patients,were significantly higher than those in their BA and the MCA blood of control group,with statistically significant differences (P＜0.05); blood flow velocity indexes,such as MFV and PI in the BA of lacunar cerebral infarction patients,were higher than those in the BA of the control group,with significant differences (P＜0.05).Lacunar cerebral infarction patients had significantly higher levels of Hcy,total cholesterol,LDL-C,tdglycerides,and HDL-C as compared with control group,with statistical differences (P＜0.05).Linear correlation analysis showed that PI of MCA and BA and Hcy level were positively correlated in lacunar infarction patients (r=0.530,P=0.020; r=0.450,P=0.010); and HDL-C and Hcy levels had negative correlation (r=-0.308,P=0.010).Conclusion A significant association between plasma Hcy and PI of cerebral arteries and serum HDL-C level indicates that Hcy plays a role in the increase of distal arterial resistance in lacunar infarction.

OBJECTIVE:To investigate the application effect of PDCA circulation method in clinical pharmaceutical care. METHODS:According to the method of PDCA cycle,clinical pharmaceutical care quality and satisfaction degree of physicians, nurses and patients in 2013 were investigated to find out the problems;the reasons were analyzed and countermeasures were made out,checked and implemented. Finally,the quality of clinical pharmaceutical care,the medical staff and patient's satisfaction with clinical pharmaceutical care were compared before and after the implementation of PDCA circulation. RESULTS:Due to the poor quality of clinical pharmaceutical care and low satisfactory degree of our hospital,we formulated related countermeasures,such as enhancing the medication service skill of clinical pharmacists in obstetrics and gynecology department,extending the coverage of pharmaceutical ward round,developing the pharmaceutical care for patients with high risk pregnancy or underwent assisted repro-duction,strengthening communication and propaganda of medical staff and patients. After the implementation of countermeasures, the quality indicators of clinical pharmaceutical care were improved in 2014,compared to 2013,such as the number of patients in-cluded in pharmaceutical ward round increased from 445 to 1 780;total number of reasonable medication intervention suggestion in-creased from 14 to 29;that of pharmaceutical consultation increased from 8 to 23;the satisfaction degree of medical staff and pa-tients improved from 55.93% and 45.95% to 100% and 92.10%,respectively. CONCLUSIONS:PDCA circulation can significant-ly improve the quality of clinical pharmaceutical care and satisfactory degree of our hospital,and promote pharmaceutical care of our hospital.

Objective: To investigate the efficacy and safety of CD19 chimeric antigen receptor T (CAR-T) lymphocytes for the treatment of B cell lymphoma. Methods: A total of 22 patients with B-cell lymphoma from February 1, 2017 to July 1, 2018 were reviewed to evaluate the efficacy and adverse reactions of CD19 CAR-T. Results: Of 22 patients with B-cell lymphoma received CD19 CAR-T cells, the median dose of CAR-T cells was 7.2 (2.0-12.0) ×10⁶/kg. Nine of 12 cases of relapse refractory patients were overall response. Complete remission (CR) occurred in 2 of 12 patients, partial remission (PR) in 7 of 12 patients. The overall response in minor residual disease positive (MRD) group was 8 of 10 patients. CD19 CAR-T cells proliferated in vivo and were detectable in the blood of patients. The peak timepoints of CAR-T cells proliferated in the relapsed refractory and MRD positive groups were 12 (5-19) and 4.5 (1-12) days after treatment respectively, and among peripheral blood cells, CAR-T cells accounted for 10.10% (3.55%-24.74%) and 4.02% (2.23%-28.60%) of T lymphocytes respectively. The MRD positive patients achieved sustained remissions during a median follow-up of 8 months (rang 3-18 months) . None of all the patients relapsed during a median follow-up time of 10 months (3-18 months) . However, 7 PR responders of the relapsed refractory patients maintained a good condition for 1.5-6.0 months. One patient bridged to hematopoietic stem cell transplantation, another one sustained remission for 12 months. Cytokine-release syndrome (CRS) occurred in 14 patients with grade 1-2 CRS in MRD positive group and grade 3 CRS in relapsed refractory group. Conclusions CAR-T cell therapy not only played a role in the rescue treatment of relapsed and refractory patients, but also produced a surprising effect in the consolidation and maintenance of B-cell lymphoma. CD19 CAR-T cells might be more effective in the treatment of MRD positive B-cell lymphoma patients than in the refractory or relapsed cases. High response rate was observed with fewer adverse reactions.

Objective To study the levels of antibodies against bordetella pertussis among pregnant women and neonates in Beijing. Method From December 2016 to March 2017, pregnant women and their newborns from three women and children′s hospitals in Beijing were enrolled in this study. 3 ml of venous blood from the mothers and 3 ml of umbilical cord blood from neonates were drawn.Pertussis bacillus IgG antibody (PER-IgG) and pertussis toxin IgG antibody (PT-IgG) were tested using enzyme-linked immunosorbent assay. χ2 test was used to compare the positive rate of pertussis IgG antibodies in maternal and cord blood in the three hospitals. Correlational analyses of the antibodies levels in each hospital were conducted. The demographic characteristics, history of cough during pregnancy and history of DTaP vaccination of the mothers were collected via questionnaires. Result A total of 612 pairs of venous blood and cord blood samples were collected, including 4 mothers delivered twins and 616 cases of cord blood sample were collected. No history of pertussis were found in the 612 mothers. Among the 616 cases of umbilical cord blood, positive rate of PER-IgG was 13.3％ (82/616), positive rate of PT-IgG was 0.5％ (3/616). Among 612 cases of venous blood from the mothers, positive rate of PER-IgG was 7.7％ (47/612), positive rate of PT-IgG was 0.3％ (2/612). Positive rates of PER-IgG and PT-IgG in the mothers′ venous blood were not correlated with their residences (P=0.676 and 0.544). Positive rates of PER-IgG (r=0.842, P<0.001) and PT-IgG (r=0.619, P<0.001) in the mothers′ blood were positively correlated with the positive rate in umbilical cord blood. Conclusion This study shows that the positive rate of PER-IgG is very low in the maternal and umbilical cord blood in Beijing. Positive correlations of PER-IgG and PT-IgG between mother and umbilical cord blood were existed. Most mothers and their newborns do not have enough protection against pertussis.
