Humanized monoclonal antibodies(mAbs) are increasingly widely used in targeted therapy for cancer and some other major diseases.Complementarity-determining region(CDR) grafting makes quantities of humanized mAbs available.Herein,we provide an overview on the strategy and progress of CDR grafting.

Prostate cancer is a most common malignant neoplasm in males. In recent years, its incidence has been rising dramatically in China. Patients with recurrent prostate cancer may be treated with androgen deprivation strategies, but most cases will eventually develop into androgen-independent prostate cancer (AIPC). Until recently, chemotherapy has been shown to be effective in palliating the symptoms of the disease but not in improving survival. Current strategies for the treatment of AIPC have shown significant palliation, but no definitive increase in survival. Molecular mechanisms underlying the development of androgen-independent prostate cancer (AIPC) are poorly understood. However, there is growing evidence that different molecular profiles may result in the development of AIPC. In this paper, we not only review the molecular mechanism of AIPC, but also present some of the promising management principles and systemic chemotherapy options against AIPC.

Objective To study the risk factors of hyperthyroid heart diseases(HHD) by analyzing clinical features of patients in order to provide a scientific basis for prevention and treatment of HHD. Methods Nine hundred and eighty two cases were selected as objective from in-patient data of Thyroid Disease Treatment Centre of Shandong Province. The cases were divided into hyperthyroidism group and HHD group. The variables of etiology,sex, age, duration of disease, TSH, FT3, FT4 and TRAb were analyzed by comparative analysis. The risk factors were analyzed by logistic regression. Results The prevalence of hyperthyroidism complicated hyperthyroid heart disease was 7.7%(76/982), age, duration of diseases, FT3, TRAb in the HHD group were [(51.4 ± 11.5), (6.3 ±2.1) years, 21.6 pmol/L, 71.6 U/L], in hyperthyroidism group were [(37.9 ± 9.8), (2.6 ± 1.3) years, 14.9pmol/L, 49.6 U/L]. The differences were statistically significant(u = 9.93,15.23, T = 44954,48792.5, P ＜ 0.05)between the two groups. The factors of the older, higher FT3 and TRAb, longer duration, Graves disease (OR =1.751,1.470,1.483,1.445,1.234) increased the risk of HHD. Conclusions Graves disease, longer duration, old age, higher FT3 and TRAb are the risk factors of HHD. Timely prevention and control of risk factors is necessary to reduce the incidence of HHD.

OBJECTIVETo compare the short-term clinical outcome between unilateral fixation fusion (ULF) and minimally invasive spine transforaminal lumbar interbody fusion (MIS-TLIF) in treating lumbar disc herniation (LDH).

METHODSThe clinical data of 39 patients with LDH were retrospectively analyzed from June 2008 to March 2013. There was 22 males and 17 females, aged from 45 to 75 years old with an average of 56.9 years. Therer were 3 cases in L3,4, 15 cases in L4,5, 21 cases in L5S1. Among them, 21 patients underwent unilateral fixation fusion (ULF group) and 18 underwent minimally invasive spine transforaminal lumbar interbody fusion (MIS-TLIF group). Operation time, blood loss, the times of radiographic exposure and hospital stay were noted and compared between two groups. Radiograph informations were regularily accessed and VAS, ODI scores were recorded at 3 days and 3, 6, 12 months after operation, respectively. According to modified Macnab criteria, the clinical effects were evaluated at final follow-up.

RESULTSAll operations were successful without severe complications. The averaged operative time and the times of radiographic exposure in ULF group [(95 ± 25) min and (4.2 ± 0.4) times] were less than that of MIS-TLIF group [(120 ± 35) min and (10.1 ± 3.9) times] (P < 0.05). But, the mean blood loss and hospital stay in MIS-TLIF group [(75 ± 45) ml and (7.2 ± 2.2)d ]were less than that of ULF group [(165 ± 60) ml and (11.0 ± 3.7) d] (P < 0.01). All patients were followed up from 12 to 45 months with an average of 29.5 months. The VAS and ODI score had significantly improved during the follow-up and no significant differences were found between two groups at the same time point (P > 0.05). The postoperative radiographs showed internal fixation position was good. And all patients obtained bone fusion by CT scan at 1 year after operation. There was no significant differences in modified Macnab criteria between two groups at the latest follow-up (P > 0.05).

CONCLUSIONFavorable short-term clinical effects can be achieved in suitable LDH patients with ULF or MIS-TLIF surgical procedures.

To explore the roles of regulatory peptides in the process of various anaphylactic inflammation of the airway, we observed the influence of four peptides, i.e., vasoactive intestinal peptide (VIP), epidermal growth factor (EGF), endothelin-1 (ET-1), and calcitonin gene-related peptide (CGRP), on the adhesion of eosinophil (EOS) to unstimulated and O(3)-stressed bronchial epithelial cells (BEC). From the experiments we observed that VIP and EGF decreased EOS adherence to O(3)-stressed BEC and downregulated airway inflammation; ET-1 and CGRP increased the adhesion of EOS to BEC in the inflammatory process; and CGRP aggravated O(3)-stressed reactions. The effects of ET-1 and CGRP were inhibited by W(7)and H(7). Anti-ICAM-1 antibody inhibited the adhesion of EOS to BEC, which brings to light that EOS adherence to BEC may be related to the expression of ICAM-1 of BEC.

To explore the role of regulatory peptides in the secretion of bronchial epithelial cells (BECs), we observed the effects of four peptides, i.e.vasoactive intestinal peptide (VIP), epidermal growth factor (EGF), endothelin-1 (ET-1), and calcitonin gene-related peptide (CGRP), on the secretion of ILs from unstimulated or O3-stressed BECs. The results of the experiments showed that VIP exerted an inhibitory effect on the secretion of IL-1 and IL-8 from unstimulated and O3-stressed BECs, VIP also decreased the secretion of IL-5 from O3-stressed BECs; EGF promoted secretion of IL-1 and IL-8 from unstimulated BECs, but decreased the secretion of ILs from O3-stressed BECs; ET-1 and CGRP enhanced the secretion of IL-1, IL-5, and IL-8 from unstimlated BECs, CGRP also increased the secretion of ILs from O3-stressed BECs. The results obtained demonstrate that intrapulmonary regulatory peptides modulate the secretion of ILs from BECs, and may play an important part in transduction of inflammatory signals.

OBJECTIVETo investigate stress distribution of different material restored post-cores in dentine and provide a theoretical guidance for clinical use.

METHODSA three-dimensional finite element model of maxillary central incisor restored with post-core and PFM crown was constructed by SCT scan technology. Based on this model, stress distribution in dentine was analyzed before and after post-core restorations with 6 different materials, including cast Ni-Cr alloy, cast titanium alloy, cast gold alloy, glass fiber reinforced composite, polythene fiber reinforced composite, and common composite resin.

RESULTSWhen the tooth was restored with cast Ni-Cr alloy post and PFM crown, the maximum tensile stress and Von Mises stress in dentin at post apex increased 152% and 162% respectively, compared with a tooth restored only with PFM crown. If polythene fiber reinforced composite was used as post material, the stress distribution did not significantly change. When the other materials were used for the post, the stress distribution changed greatly. The elastic modulus of post-core materials affected the stress distribution pattern in dentine.

CONCLUSIONThe materials with elastic modulus similar to that of dentin, such as polythene fiber reinforced composite, may be suitable for post restoration.
