Objective To observe the clinical efficacy and adverse reactions of tigecycline in treatment of health-care-associated pneumonia (HAP ) caused by extensively drug-resistant Acinetobacter baumannii (XDRAB ). Methods Clinical data of patients who used tigecycline for the treatment of XDRAB HAP in intensive care units of a hospital from March 2013 to June 2014 were retrospectively analyzed.Results XDRAB isolated from 31 patients with HAP were all sensitive to tigecycline,the resistance rates to carbapenems and sulbactams (including cefopera-zone-sulbactam,SCF)were all 100%,17 cases (54.84%)were mixed infection.Combined use rates of tigecycline and SCF were 85.71 %(12/14)in respiratory intensive care unit(RICU)and 47.06%(8/17)in general intensive care unit(GICU).Of 31 patients,the cure rate,effective rate,bacterial clearance rate,and antimicrobial adverse reac-tion rate were 29.03%,45.16%,61 .29%,and 16.13% respectively,no serious adverse drug reactions occurred. In RICU group and GICU group,the cure rates were 42.86% and 17.65% respectively,effective rates were 71 .43% and 23.53% respectively,and bacterial clearance rates were 78.57 % and 47.06% respectively,difference in effective rate between two groups was significant (P <0.05).Among patients receiving combination of tigecycline and SCF as well as not receiving combined SCF,the cure rates were 35.00% and 18.18% respectively,effective rates were 60.00% and 18.18% respectively,and bacterial clearance rates were 65.00% and 54.55% respectively, difference in effective rate between two groups was significant (P <0.05).Conclusion Tigecycline has a good clini-cal efficacy and little adverse reaction in treating XDRAB HAP;tigecycline combined with SCF is a good choice.

Objective To analyze the mRNA expression level of lymphoid enhance factor 1 (LEF-1), and to investigate its clinical significance in bone marrow mononuclear cells of patients with chronic myeloid leukemia chronic-phase (CML-CP) after initial diagnosis and chemotherapy, and to analyze its clinical significance. Methods The real-time fluorescence quantitative polymerase chain reaction was used to measure the expression level of LEF-1 gene in 38 CML-CP patients after initial diagnosis and chemotherapy and 20 persons without blood system diseases and neoplastic diseases as normal control. The difference of LEF-1 expression level between the patients and healthy control was compared, and the effect of imatinib on the main molecular response (MMR) was analyzed. Results The expression of LEF-1 mRNA in 38 newly diagnosed patients [0.00214 (0.00020 - 0.02120)] was significantly higher than that in normal controls [0.00101 (0.00009 - 0.00233)] (U= 163.0, P< 0.01). The expression of LEF-1 mRNA in MMR group [0.00107 (0.00010 - 0.00519)] was significantly lower than that in non-MMR group [0.01015 (0.00091 -0.03615)] (U= 25.0, P< 0.01). There was no significant difference in LEF-1 mRNA expression between the normal control group and the MMR group after imatinib treatment (U= 201.0, P> 0.05). The level of LEF-1 mRNA expression of non-MMR group was also higher than that of the normal control group (U= 14.0, P<0.01). The rate of acquiring MMR was significantly higher in high LEF-1 mRNA expression group [84.2 %(16/19)] than that in low expression group [47.4%(9/19)] (χ2=4.209, P<0.01). The time of acquiring MMR was significantly shorter in the high LEF-1 mRNA expression group [(10.0 ± 4.5) months] than that in the low expression group [(14.6 ± 3.8) months] (t= 2.705, P< 0.01). Conclusions LEF-1 may be involved in the occurrence and development of CML, and reflects the tumor burden. It may be one of the indicators to predict the efficacy of imatinib.

Objective: To explore the relationship between expression of tumor necrosis factor-α( TNF-α) and electrophysiological heterogeneity in isolated heart tissues and isolated rat ventricular myocytes.The arrhythmogenic mechanisms of TNF-αwere further studied.Methods:Langendorff perfused heart tissues models were used to verify the arrhythmogenic effects of TNF-α.The monophasic action potentials( MAPs) of the endocardium and epicardium from the isolated heart tissues were recorded by elec-trophysiological experiments.The isolated rat ventricular myocytes were obtained by enzymatic dissociation.K+currents(Ito,IK1)were recorded by using whole cell patch clamp technique.Results: Compared to the control group, the difference in MAPD between endocardium and epicardium dramatically increased with TNF-α( P<0.05 ) .TNF-αcould cause MAP duration ( MAPD ) prolongation, and a single dose of TNF-αdifferentially affected the MAPs of endocardium and epicardium of isolated heart tissues.Compared to the control group,the K+currents(Ito,IK1)were dose-dependently decreased with TNF-αin rat ventricular myocytes(P<0.05).However, etanercept had no effects on the MAPD in the absence of TNF-α.Conclusion:TNF-α-induced heterogeneity of MAPD between the endo-cardium and epicardium may provide the substrate for the onset of ventricular arrhythmias during acute myocardial infarction.The effect might be associated with TNF-αcontribute to re-entrant ventricular arrhythmias which resulted from decreased K+currents(Ito,IK1).

This study aimed at exploring a fast method to accurately identify the medicinal insect Vespa mandarinia Smith from its adulterants using DNA barcode and COI sequences.The extracted DNAs from V.mandarinia and its adulterants V.soror were amplified by polymerase chain reaction (PCR) and sequenced bilaterally based on COI barcode sequence investigation.The information of the COI sequences of V.mandarinia and V.soror were gathered from GenBank.All the sequences were compared and analyzed,and their intraspecific and interspecific genetic distances were calculated using MEGA 6.06.In addition,the phylogenetic tree was established with neighbor-joining (NJ) method.As a result,the COI sequences of V.mandarinia and V.soror were successfully amplified.The minimum interspecific distance between V.mandarinia and its adulterants was 0.152 ± 0.017,being considerably larger than the maximal intraspecific distance between V.mandarinia,0.009±0.004.The constructed phylogenetic tree showed an independent branch for each species.It was concluded that the DNA barcode based on COI sequence can efficiently identify V.mandarinia and its adulterants.This study provided an innovative tool for the quality control and market regulation of Chinese materia medica,securing the safe medication of V.mandarinia.

Objective To quantitatively analyze the mRNA expression level of lymphoid enhance factor 1 (LEF-1) in bone marrow mononuclear cells of patients with acute myeloid leukemia (AML) at intermediate-risk after initial diagnosis and chemotherapy, and to analyze its clinical significance. Methods The real-time fluorescence quantitative polymerase chain reaction (RT-PCR) was used to measure the expression level of LEF-1 gene in AML patients at intermediate-risk after initial diagnosis and chemotherapy, and its relationship with effectiveness and survival were analyzed. Results The LEF-1 mRNA level in preliminarily diagnosed patients with AML was significantly higher than that in control arm [0.00519 (0.00015-0.09207) vs. 0.00101 (0.00009-0.00233)], and the difference was statistically significant (u=134.50, P<0.01). The LEF-1 mRNA level in patients after chemotherapy was significantly declines as compared to that in patients before chemotherapy [0.00107 (0.00008 - 0.00744) vs. 0.00519 (0.00015 - 0.09207)], and the difference was statistically significant (u= 317.00, P< 0.01) and LEF-1 mRNA expression level before chemotherapy in complete remission (CR) patients was significantly higher than that in non-CR patients [(0.01108 (0.00164 - 0.09207) vs. 0.00110 (0.00015 - 0.00916)], and the difference was statistically significant (u=19.00, P<0.01). High LEF-1 expression predicted a significantly better overall survival in AML patients with intermediate-risk cytogenetics (χ2= 4.549, P= 0.033). Conclusions LEF-1 may be involved in the development and progression of AML at intermediate-risk patients and is closely related to tumor burden and treatment efficacy. LEF-1 may be a good predictor of better prognosis and a novel target for therapeutic effect.

OBJECTIVETo investigate the effects of 17β-estrogen on expressions of C-reactive protein (CRP) and its mRNA in vascular smooth muscle cells(VSMCs).

METHODSImmunocytochemistry was used to detect CRP level in normal VSMCs. The expressions of C-reactive protein and p-ERK1/2 in Ang-II-stimulated VSMCs were evaluated with Western blot. C-reactive protein mRNA was examined with RT-PCR.

RESULTS17β-estrogen had no effect on cell morphology and C-reactive protein expression in normal VSMCs; however, C-reactive protein and mRNA, as well as p-ERK1/2 were decreased in Ang-II-stimulated VSMCs after 17β-estrogen treatment in a concentration-dependent manner.

CONCLUSION17β-estrogen may inhibit the expression of C-reactive protein and its mRNA in Ang-II-stimulated VSMCs via ERK1/2 signal transduction pathway in a concentration-dependent way.

Objective To investigate the clinical characteristics and prognostic factors after percutaneous coronary intervention of women with the first non-ST-segment elevation myoeardial infarction.Methods A total of 123 female patients with AMI,including 70 patients with NSTEMI and 53 patients with ST-segment elevation myocardial infarction (STEMI),who received PCI within 24 hours of onset were selected from June 2013 to June 2015.The clinical data were compared between patients with NSTEMI and with STEMI.Cox regression model was used to analyze the prognostic factors for the elderly patients with NSTEMI.Results The female patients with NSTEMI had more cases of patients with hypertension (48 vs.26),diabetes (38 vs.38) and hyperlipidemia (52 vs.29)than the female patients with STEMI.Significant differences in systolic blood pressure [(134.31±22.26)mmHg vs.(125.04 ± 19.63) mmHg],levels of white blood cell [(9.02 ± 3.75) 109/L vs.(11.37 ± 3.63) 109/L] and troponin Ⅰ [(8.63 ± 18.34) μg/L vs.(18.79 ± 27.76) μg/L] were observed in the above two groups (l P ＜ 0.05,respectively).The rates of revascularization,major adverse cardiovascular events in NSTEMI group were higher than those in STEMI group during 1 year after discharge (47.7％ vs.28.0％,62.9％ vs.35.8％) (P ＜ 0.05,respectively).Cox survival analysis showed that white blood cell (HR =1.241) and troponin-Ⅰ (HR =1.026) elevation were the risk prognostic factors after PCI for women with the first NSTEMI.Conclusion More hypertension,diabetes,hyperlipidemia and higher levels of systolic blood pressure,lower levels of white blood cell and troponin Ⅰ were observed in women with the first NSTEMI.The long-term prognosis of female patients with NSTEMI is poor.And elevated levels of white blood cell and troponin-Ⅰ were the risk prognostic factors after PCI for women with the first NSTEMI.

Objective To investigate the mRNA level of lymphoid enhancing factor-1 ( LEF-1) in bone marrow mononuclear cells after the initial diagnosis and chemotherapy of patients with multiple myeloma (MM) and its clinical significance. Methods The LEF-1 mRNA of target gene in 42 MM patient was detected by real-time fluorescence quantitative polymerase chain reaction (RTQ-PCR), and 20 patients without hematological disease were enrolled as the healthy controls. Results The LEF-1 mRNA median level in previously diagnosed MM patients was significantly higher than that in the healthy controls [0.01068 (0.00017 - 0.14100) vs. 0.00101 (0.00009 - 0.002326)], and the difference was statistically significant (U = 91.00, P< 0.001); The LEF-1 mRNA median level in MM patients after chemotherapy was declined compared with the patients before chemotherapy [0.00011 (0.00001 - 0.01548) vs. 0.01068 (0.00017 -0.14100)], and the difference was statistically significant (U = 343.0, P< 0.001). The LEF-1 mRNA median level of MM patients after chemotherapy in progression of disease (PD) group was higher than that in the non-PD groups [0.08386 (0.00288 - 0.14100) vs. 0.003454 (0.000156 - 0.05660)], and the difference was statistically significant (U = 343.0, P< 0.001). The overall survival (OS) rate in the high LEF-1 expression group was shorter than that in the low LEF-1 expression group for MM patients in the initial diagnosis (47.6%vs. 65.5 %, χ2 = 3.931, P= 0.0414). Conclusion LEF-1 may be involved in the occurrence and development of MM, which has a potential to become an indicator of evaluating the poor prognosis and PD of MM patients, and could be served as a novel therapy target for the treatment of MM.

Objective: To investigate the osteogenic effect of β-tricalcium phosphate (β-TCP) and bone morphogenetic protein-2 (BMP-2) in the repair of the alveolar cleft. Methods : Fifty-nine patients with unilateral alveolar cleft who visited Capital Medical University School of Stomatology from January 2016 to May 2021 were included. They were divided into three groups according to the different bone repair materials: autologous bone, β-TCP and BMP-2 +β-TCP. The preoperative and postoperative CBCT data of the patients were imported into Mimics 21.0 software. The preoperative volume of the bone defect and the new volume of bone formation were calculated by the three-dimensional reconstruction method. The osteogenesis rate was calculated to evaluate the osteogenesis effect Results: The wounds in the three groups healed well after the operation, without implant material discharge, infection, dehiscence, rejection or other symptoms. Twelve months after the operation, CBCT scanning and three⁃dimensional reconstruction images of the three groups of patients showed the formation of new bone bridges in the alveolar ridge fissure area. The image density of the new bone tissue was not significantly different from that of normal bone tissue, and the continuity of the maxilla was re⁃ stored to varying degrees. The bone rate of autogenous bone was 65.00% ± 16.66%, β⁃ TCP group and BMP⁃2+ β⁃ The bone composition rate of TCP was 69.82% ± 17.60%, 71.35% ± 17.51%, respectively, and there was no significant dif⁃ ference compared with the autogenous bone group (P = 0.382, P = 0.244). The β⁃TCP and BMP⁃2+ β⁃TCP groups had no significant differences in bone rate (P = 0.789). Conclusion β⁃TCP could be used to replace autologous bone for alveolar cleft repair. The addition of BMP⁃2 to β⁃TCP did not significantly improve the osteogenesis rate.
