[A Predictive Model for Hemoglobin Change before and after Collection of Apheresis Autologous Red Blood Cells in Patients].

Objective: To analyze the affecting factors of hemoglobin changes in apheresis red blood cells (RBCs), and to establish a predictive model for the evaluation of apheresis.

Methods: The clinical data of 130 patients undergoing selective surgery for apheresis autologous RBCs from January 2017 to December 2018 were collected. The change of hemoglobin and its affecting factors before and after apheresis were analyzed.

[Factors Influencing Mononuclear Cell Collection in Tumor Cell Biotherapy].

Objective: To investigate the factors affecting counting and collection efficiency of the final product- mononuclear cells (MNCs) in the collection of mononuclear cells for tumor cell biotherapy.

Methods: The collected data of 142 tumor patients and healthy donors were analyzed, including age, sex, height, weight, BMI, the total blood volume, diagnostic category, vascular access, operator, final product volume, ACD anticoagulant usage, flow rate and circulation times, pre-apheresis Hb, RBC, Plt, WBC, lymphocyte count, monocyte count, neutrophil count, circulating blood volume without anticoagulant, final product MNC and collection efficiency of MNC. CE(collection efficiency)%= final product MNC×100/(pre-apheresis MNC×circulating blood volume without anticoagulant).

[Study of biological characteristics of the IVpi-189 virus derived from persistent influenza A virus-infected cell line].

To investigate biological characteristics of the IVpi-189 progeny virus derived from the culture of influenza A virus as a live-attenuated vaccine candidate. Persistent infection of a cultured cell line with influenza A virus (MDCK-IVpi) was established by incubating continuously influenza virus-infected cells at a lower temperature. The infectious progeny virus derived from MDCK-IVpi cells at the 189rd subculture was designated as the IVpi-189 strain of influenza virus.

Evaluation of models of the mechanisms underlying intron loss and gain in Aspergillus fungi.

Although intron loss and gain have been widely observed, their mechanisms are still to be determined. In four Aspergillus genomes, we found 204 cases of intron loss and 84 cases of intron gain. Using this data, we tested common hypotheses of intron loss or gain.

[Comparison of the effects resulted by modified maxillary oblique plate and Twin-block in advancing mandible].

Unlabelled: URPOSE: The aim of this study was to evaluate the effects resulted by modified maxillary oblique plate in advancing mandible.

Methods: Twelve Class II division II cases (4 males, 8 females) with mandibular retrusion were selected as group 1 aligned by fixed appliances in the upper arches, and their mandibles were advanced by the modified maxillary oblique plates. Meanwhile, twelve Class II division II cases (5 males, 7 females) with mandibular retrusion were selected as group 2 treated with the Twin-block.
