ABSTRACT
Chimeric antigen receptor T (CAR-T) cell therapy is a novel cellular immunotherapy that is widely used to treat hematological malignancies, including acute leukemia, lymphoma, and multiple myeloma. Despite its remarkable clinical effects, this therapy has side effects that cannot be underestimated. Cytokine release syndrome (CRS) is one of the most clinically important and potentially life-threatening toxicities. This syndrome is a systemic immune storm that involves the mass cytokines releasing by activated immune cells. This phenomenon causes multisystem damages and sometimes even death. In this study, we reported the management of a patient with recurrent and refractory multiple myeloma and three patients with acute lymphocytic leukemia who suffered CRS during CAR-T treatment. The early application of tocilizumab, an anti-IL-6 receptor antibody, according to toxicity grading and clinical manifestation is recommended especially for patients who suffer continuous hyperpyrexia, hypotensive shock, acute respiratory failure, and whose CRS toxicities deteriorated rapidly. Moreover, low doses of dexamethasone (5-10 mg/day) were used for refractory CRS not responding to tocilizumab. The effective management of the toxicities associated with CRS will bring additional survival opportunities and improve the quality of life for patients with cancer.

ABSTRACT
OBJECTIVE:To study the effects of rosiglitazone(RH)on body weight,FPG,FFA and other indicators in diabe-tes model rabbit. METHODS:18 rabbits were evenly randomized into control group,model group and dextran group. The latter 2 groups were given alloxan intravenously to induce diabetes model. 3 groups were given RH(0.5 mg/kg)intragastrically,and dex-tran group was additionally given dextran 40 glucose injection(5 ml/kg)intravenously,once a day,for consecutive 3 weeks. Body weight,serum level of FPG,FFA,AngⅡ and NO were determined before and after medication. RESULTS:Compared with be-fore medication,body weight of rabbits in control group were increased after medication,while the levels of FFA and AngⅡ were decreased;the levels of FPG and FFA were decreased in model group;body weight of rabbits were decreased in dextran group af-ter medication,with statistical significance (P0.05). The level of FFA in dextran group was higher than in model group after medication,with statistical significance(P<0.01). CONCLUSIONS:Rosiglitazone can lead to weight gain by a mechanism which reduce the level of FFA.

ABSTRACT
The different growing habitats of Bupleurum chinense were investigated in Donglin mountain & Wuling mountain areas, the saikosaponin a and d in samples of B. chinense collected from different habitats were determined by HPLC. Results showed that B. chinense distributed in various habitats, such as meadow, understory and brushy. Significant differences of saikosaponin contents were observed. The higher saikosaponins contents were showed in samples from meadow habitats, while the lower saikosaponins contents in samples from understory and brushy habitats. The ventilation situation and light condition showed positive correlation with the saikosaponins accumulation in B. chinense. It could be concluded that growing habitats play an important role in accumulation of saikosaponins in B. chinense.

We report a complete genomic sequence of rare isolates (minor genotype) of the SARS-CoV from SARS patients in Guangdong, China, where the first few cases emerged. The most striking discovery from the isolate is an extra 29-nucleotide sequence located at the nucleotide positions between 27,863 and 27,864 (referred to the complete sequence of BJ01) within an overlapped region composed of BGI-PUP5 (BGI-postulated uncharacterized protein 5) and BGI-PUP6 upstream of the N (nucleocapsid) protein. The discovery of this minor genotype, GD-Ins29, suggests a significant genetic event and differentiates it from the previously reported genotype, the dominant form among all sequenced SARS-CoV isolates. A 17-nt segment of this extra sequence is identical to a segment of the same size in two human mRNA sequences that may interfere with viral replication and transcription in the cytosol of the infected cells. It provides a new avenue for the exploration of the virus-host interaction in viral evolution, host pathogenesis, and vaccine development.

The E (envelope) protein is the smallest structural protein in all coronaviruses and is the only viral structural protein in which no variation has been detected. We conducted genome sequencing and phylogenetic analyses of SARS-CoV. Based on genome sequencing, we predicted the E protein is a transmembrane (TM) protein characterized by a TM region with strong hydrophobicity and alpha-helix conformation. We identified a segment (NH2-_L-Cys-A-Y-Cys-Cys-N_-COOH) in the carboxyl-terminal region of the E protein that appears to form three disulfide bonds with another segment of corresponding cysteines in the carboxyl-terminus of the S (spike) protein. These bonds point to a possible structural association between the E and S proteins. Our phylogenetic analyses of the E protein sequences in all published coronaviruses place SARS-CoV in an independent group in Coronaviridae and suggest a non-human animal origin.
