Rituximab is the first monoclonal antibody that has been approved for the treatment of lymphoma. Rituximab has shown significant efficacy in the treatment of B-cell non-Hodgkin's lymphomas, such as diffuse large B-cell and follicular lymphomas. Maintenance therapy with rituximab has further improved the prognosis in patients with follicular lymphoma. These patients responded to induction treatment. This antibody treatment has been recommended in treatment guidelines. The treatment strategy for lymphoma has continuously improved. Recent studies focused on how to improve the definition of the indication for maintenance therapy and how to optimize the current maintenance regimens. In this review, we summarized the main studies and the most recent advances on ritux-imab maintenance therapy in patients with lymphoma.

Objective To evaluate the diagnosis and treatment of severe pancreatic trauma(SPT). Methods The clinical data of 32 patients with transected pancreatic trauma(grade 3-5) admitted into our hospital in recent 20 years were retrospectively analyzed. Results Twenty patients were in grade 3, 10 in grade 4,and 2 in grade 5. Operations were performed on all 32 patients. Twenty-five recovered, and 7 died. The mortality was 21.9%.Before the operation, peritoneal lavage fluid amylase rose in 10 patients(50%),and serum amylase rose in 12 patients(60%). Imaging examination included ultrasonography in 10 (diagnosed in 3),and CT in 8 (diagnosed in 3). Diagnosis was established only in 10 patients before the operation. Complications included fistula, abscess and pseudocyst. Conclusions Incidence of associated trauma is high. The preoperative diagnosis of pancreatic trauma is difficult. The rates of morbidity and mortality are high. Early diagnosis, careful exploration and proper surgery are very important. Intraoperative pancreatography or ultrasonographic scanning is useful in diagnosis. Somatostatin and human growth hormone are useful in the treatment.

The Arabidopsis thaliana glutathione S-transferases zeta class (AtGSTZ) is a multi-functional enzyme, which plays important role in cellular metabolism and environmental purification. Error-prone PCR and cycles of DNA shuffling were used to construct a mutagenesis library of AtGSTZ. The screening of the resultant libraries was carried out by a pH indicator dye-based colorimetric assay. Nine mutants which enhanced the dichloroacetic acid dechlorination activity were obtained. Among them, NN23 contained 25 amino acid substitutions with the activity improving 120%, whereas NN20 contained 24 amino acid substitutions with the activity improving 102%. EC1 contained 2 amino acid substitutions with the activity improving 47%. The rest 6 mutants contained one amino acid substitution with their activity increasing from 9% to 60%. The enzymatic characterization showed that all the evolved enzymes increased their catalytic efficiencies towards dichloroacetic acid and binding affinity towards glutathione whereas some of them increased the renaturability. However there is no obvious change in their thermostability. Based on these data, functional residues related to catalysis and refolding of AtGSTZ were discussed.

This study was aimed to explore pharmacological effects of epimedium pubescen flavonoid (EPF) on biomechanical properties among ovariectomized rats. Sixty female Sprague-Dawley (SD) rats (aged 2-month-old) were randomly divided into six groups (n = 10), which were the sham control group (Group A), the model group (GroupB), the standard group (Group C), the treated 1 group (Group D), the treated 2 group (Group E), and the treated 3 group (Group F). Except the sham control group (Group A), rats in other groups had been ovariectomized. All rats were given the same feedstuff. Meanwhile, Group C was given calcium 75 mg·kg-1 combined with VitD3 21 IU·kg-1 by gastrogavage every day for 4 months; Group D was given EPF 75 mg·kg-1; Group E was given EPF 150 mg·kg-1;Group F was given EPF 300 mg·kg-1. At the end of the 4th month, all rats were sacrificed. Bones, which included tibia, femur and humerus of both sides and all lumbar vertebra bodies, had been taken out. Measurement was made on the elastic modulus, maximum loading capability, maximum stress, potential energy of deformation, and structural rigidity of biomechanical properties of the fourth lumbar vertebra body (LV4); the maximum loading capability, bone break load, potential energy of deformation, structural rigidity of the structural dynamics properties of the femur com-pact bone; the elastic modulus, maximum stress, maximum inherent strain, bone break stress, and bone break strain of the mechanical properties of a material of the femur compact bone in the experimental rats. The results showed that compared with Group B, the elastic modulus, maximum loading capability, maximum stress, potential energy of deformation, and structural rigidity of LV4; the maximum loading capability, bone break load, potential energy of de-formation, structural rigidity of the structural dynamics properties of the femur compact bone; the elastic modulus, maximum stress, maximum inherent strain, and bone break strain of the mechanical properties of a material of the fe-mur compact bone were obviously increased in Group A, D, E and F (P< 0.05). Group C had increasing tendency. There were no statistical differences among Group A, C, D, E and F. Group D, E, and F had increased with EPF dose-dependently. However, there were no statistical differences among them. There were no statistical differences on bone break strain of the mechanical properties of a material of the femur compact bone among Group A, C, D, E, and F. It showed that ovariectomization reduced the biomechanical properties of vertebra bodies, structural dynamics properties of the femur compact bone, and the mechanical properties of a material of the femur compact bone. The application of EPF can effectively prevent and treat the decreasing of biomechanical properties of ovariectomized rats, so as to keep them in a relatively higher level.
