Abstract: Objective To investigate the distribution and drug resistance characteristics of pathogenic bacteria in patients with neutropenic acute leukemia (AL) and bloodstream infections (BSI). Methods The clinical data of 258 neutropenic acute leukemia patients with bloodstream infections, who admitted to Shengjing Hospital of China Medical University from January 2016 to December 2021, were collected and analyzed for pathogenic bacteria and drug resistance. Results A total of 268 strains of pathogenic bacteria were isolated from 258 patients, including 180 strains of gram-negative bacteria (67.16%), 61 strains of gram-positive bacteria (22.76%), and 27 strains of fungi (10.07%). Gram-negative bacteria were mainly Klebsiella pneumoniae (53/268, 19.78%), Escherichia coli (49/268, 18.28%) and Pseudomonas aeruginosa (41/268, 15.30%). Gram-positive bacteria were mainly coagulase negative Staphylococcus (31/268, 11.57%) and Staphylococcus aureus(17/268, 6.34%). The main fungi were Candida tropicalis (25/268, 9.33%). Escherichia coli (33/268, 12.31%) was the most common pathogen isolated from acute myeloid leukemia (AML), followed by Pseudomonas aeruginosa (25/268, 9.33%), coagulase-negative Staphylococcus (18/268, 6.72%) and Candida tropicalis (18/268, 6.72%). Klebsiella pneumoniae (35/268, 13.06%) was the most common pathogen isolated from acute lymphoblastic leukemia (ALL),followed by Pseudomonas aeruginosa (15/268, 5.60%) and Escherichia coli (14/268, 5.22%). The resistance of Gram-negative bacteria to piperacillin/tazobactam, cefoperazone/sulbactam, imipenem, meropenem, ertapenem, amikacin, cefoxitin, amoxicillin/clavulanic acid was low. Gram-positive bacteria were sensitive to linezolid and vancomycin. Candida was sensitive to flucytosine, amphotericin B and itraconazole. Conclusions In patients with granulosa after AL chemotherapy combined with BSI, the pathogenic bacteria isolated from AML are diverse, and the pathogenic bacteria isolated from ALL are mainly gram-negative bacteria. Pathogenic bacteria have different degrees of drug resistance to commonly used antibacterial drugs, so it is important to strengthen the monitoring of the distribution of pathogenic bacteria and the change of drug resistance and rational use of antibacterial drugs to minimize the death of patients.

Objective To report 6 cases of hydroa vacciniforme-like cutaneous lymphoma,and to inves- tigate the relationship between this disorder and Epstein-Barr virus(EBV)infection.Methods Pathological and immunohistochemical examinations were performed in the biopsy specimens obtained from all 6 patients. Skin lesions were subjected to EBV encoded RNA(EBER)detection by in situ hybridization.Serological assay and quantification of EBV DNA were performed.Results All the 6 patients had recurrent papules, papulovesicles,necrosis and variola-like scar with chronic intermittent fever;four of the patients also presented with edema of the face,hands and feet.Pathologically,there were multilocular vesicles in the epidermis,and large numbers of infiltrating lymphocytes through the dermis.The cells were atypical with mitotic figures. Immunohistochemical staining of the lesions of 4 patients showed large quantities of cells expressing CD56, scattered cells expressing CD3 and CD45RO,and cells expressing grazyme B and T cell intracellular antigen-1 (TIA-1);a diagnosis of hydroa vacciniforme-like cutaneous NK/T lymphoma was made in these 4 cases. In the lesions of another 2 patients,the cells expressing CD3 and CD45RO,but not CD56,were observed; the diagnosis of hydroa vacciniforme-like cutaneous T-cell lymphoma was made in them.EBER was detected in the tumor cells of all the 6 patients.The IgG titers of anti-Epstein-Barr viral capsid antigen increased in all patients(1:5120 in 2 cases,1:2560 in 2 cases,1:1280 in 2 cases).The copies of EBV DNA were increased in the peripheral blood of both the two detected cases.A chronic active EBV infection was confirmed in all patients.Conclusions Hydroa vacciniforme-like cutaneous lymphoma is clinically characterized by edema of face,hands and feet,vesicular eruptions and variola like scars;histologically,it is characterized by infiltrates of atypical cells consistent with lymphoma,and necrosis in the center of vessels.NK/T is the primary immunophenotype of this disease.There is a close association between chronic active EBV infection and hydroa vacciniforme-like cutaneous lymphoma.

OBJECTIVE:
To assess the reproducibility of non-verbal facial expressions (smile lips closed, smile lips open, lip purse, cheek puff) in normal persons using dynamic three-dimensional (3D) imaging and provide reference data for future research.
METHODS:
In this study, 15 adults (7 males and 8 females) without facial asymmetry and facial nerve dysfunction were recruited. Each participant was seated upright in front of the 3D imaging system in natural head position. The whole face could be captured in all six cameras. The dynamic 3D system captured 60 3D images per second. Four facial expressions were included: smile lips closed, smile lips open, lip purse, and cheek puff. Before starting, we instructed the subjects to make facial expressions to develop muscle memory. During recording, each facial expression took about 3 to 4 seconds. At least 1 week later, the procedure was repeated. The rest position (T0) was considered as the base frame. The first quartile of expressions (T1), just after reaching the maximum state of expressions (T2), just before the end of maximum state of expressions (T3), the third quartile of expressions (T4), and the end of motion (T5) were selected as key frames. Using the stable part of face such as forehead, each key frame (T1-T5) of the different expressions was aligned on the corresponding frame at rest (T0). The root mean square (RMS) between each key frame and its corresponding frame at rest were calculated. The Wilcoxon signed ranks test was applied to assess statistical differences between the corresponding frames of the different facial expressions.
RESULTS:
Facial expressions like smile lips closed, smile lips open, and cheek puff were reproducible. Lip purse was not reproducible. The statistically significant differences were found on the T2 frame of the repeated lip purse movement.
CONCLUSION
The dynamic 3D imaging can be used to evaluate the reproducibility of facial expressions. Compared with the qualitative analysis and two-dimensions analysis, dynamic 3D images can be able to more truly represent the facial expressions which make the research more reliable.

OBJECTIVETo evaluate the value of FOXP1 and Cyclin E gene in primary central nervous system lymphoma(PCNSL) of immunocompetent patients on prognostic significance.
METHODSClinical data of 71 patients with newly diagnosed PCNSL from 2002 to 2007 was analyzed retrospectively. Immunohistochemistry method (HRP-EnVision(TM)) was performed to observe the expression of FOXP1 and Cyclin E gene in tumor tissue samples. The survival was analyzed by Kaplan-Meier survival curve, survival factors analysis by the Log-rank test and COX proportional hazards regression model.
RESULTSFOXP1 positive was observed in 35 of 51 patients (68.63%) and Cyclin E staining was present in 29 of 50 cases (58.00%). FOXP1(+) patients had a shorter overall survival (OS) than FOXP1(-) ones. 2-year OS rate in FOXP1(+) and FOXP1(-) patients were 23.33% and 73.56%, respectively(P = 0.0015). Cyclin E(+) patients had a shorter overall survival(OS) than cyclinE(-) ones. 2-year OS rate in Cyclin E(+) and Cyclin E(-) patients were 17.56% and 69.76%, respectively (P = 0.0017). Multivariate analysis showed that Cyclin E expression was an independent prognostic factor for shorter OS (P = 0.048). FOXP1 expression might be an important prognostic factor for shorter OS (P = 0.065).
CONCLUSIONCyclin E expression is an independent prognostic factor and FOXP1 expression is a possible prognostic factor for poor clinical outcome in patients with PCNSL.

OBJECTIVETo study the effects of catecholamines on human preadipocyte proliferation and differentiation.
METHODSCatecholamines (epinephrine, isoprenaline and noradrenaline) were added to the culture media of human preadipocytes. The proliferation of cells, the expression of GPDH and lipid droplet accumulation in cytoplasm were observed and recorded. The functions of alpha and beta receptors were examined with adding alpha and beta receptor blockers.
RESULTSEpinephrine and isoprenaline stimulated human preadipocyte proliferation and inhibited GPDH up-regulation during differentiation. The three types of catecholamines inhibited lipid accumulation in cell differentiation. The beta-adrenoceptors played a key role during the process.
CONCLUSIONHuman preadipocytes responded to catecholamine characteristically. The result would be applicable in the study of drugs for obesity.

The objective of this study was to investigate the effect of a novel Zinc phthalocyanine (ZnPcH(1)) based photodynamic therapy (PDT) on acute monocytic leukemia cell lines SHI-1 and its mechanism, so as to provide theory basis for bone marrow purging in vitro for patients with leukemia. The killing effect of ZnPcH(1)-PDT on SHI-1 cells were assessed by MTT method; the SHI-1 cell death patterns were analyzed by AO/EB fluorescence staining, TdT-mediated dUTP nick end labeling (TUNEL), DNA ploidy analysis, and Annexin V-FITC/PI double staining.Cell mixture was established by integrating SHI-1 cells with normal bone marrow MNC (by 1:100-1:10 000). Purging effect of ZnPcH(1)-PDT against SHI-1 mixed into normal MNC was assessed by analyzing the expression of fusion gene MLL/AF6 mRNA using nested RT-PCR. The results showed that ZnPcH(1)-PDT could effectively inhibit SHI-1 cell proliferation in dose-dependent manner, and ZnPcH(1)-PDT could induce cell apoptosis in time-dependent manner. 0.5 µmol/L ZnPcH(1)-PDT could completely photoinactivated kill SHI-1 cells in the simulated remission bone marrow. It concluded that ZnPcH(1)-PDT may be a effective and convenient promising purging technique for leukemia.
