Many specific therapeutic antibody drugs have been developed for different indications. In drug development, it has been found that the antibody isotype framework can not only affect the physical and chemical properties of therapeutic antibodies, but also influence the activity and therapeutic effect. As a result, IgG isotype selection should be considered carefully in antibody drug development strategies. Because of the unique biological characteristics, IgG4 isotype has been used in some therapeutic antibodies for which effector functions are not desired. In order to provide new ideas for the development of antibody drugs, the research and application progress of IgG4 isotype in therapeutic antibody drug development has been reviewed.

Objective To observe the clinical efficacy of Qufeng Qingre Weiling Decoction combined with the decreasing amount of loratadine in treatment of chronic urticaria (CU). Methods Totally 108 CU patients were randomly divided into treatment group and control group, 54 cases in each group. The treatment group was given Qufeng Qingre Weiling Decoction combined with the decreasing amount of loratadine (10 mg, 1 time per day) according to symptom controlling situation, and control group with the decreasing amount of loratadine only. Both groups were treated for 4 treatment courses (2 weeks as a treatment course). Symptom score reduce index was used to calculate the effective rate after 8 weeks of treatment. And the taking antihistamine medicine score was recorded 4, 6, 8 weeks of treatment. The follow-up visits were made to observe long-term efficacy of the cured patients 1 month, 3 months and 6 months after discontinuing the medication. Results Totally 27 cases from the treatment group were cured, with a total short-term effective rate of 96.30%;13 cases from the control group were cured, with a total short-term effective rate of 65.38%, with statistical significance (P<0.05). The taking antihistamine medicine score in treatment group (0.553 ± 0.239) was lower than that in control group (0.721 ± 0.245), namely the symptom improvement in treatment group was better than that in control group by taking less antihistamine medicine. Long-term clinical efficacy showed that the treatment group was also distinctively better than the control group. Conclusion Qufeng Qingre Weiling Decoction combined with the decreasing amount of loratadine is more effective for CU, and with better short-term and long-term clinical efficacy than the control group.

Artificial liver support system (ALSS),as a means of bridging patients with liver failure to transplantation,has been widely used at home and abroad.However,clinical trails show that different ALSS may have different therapeutic effects.This review briefly introduces the widely-used non-biological liver support technologies and extensively-studied biological liver support technologies,and tries to give an overview on their impact on biochemical markers and survival.

Objective To investigate the short-term treatment effectiveness of the auditory integrative training(AIT) on intelligence, language and gross motor function in children with spastic cerebral palsy (CP).Methods Sixty patients with spastic CP, aged 2 to 4 years old,who had been given all the routine conventional rehabilitation at the Rehabilitation Department of the People's Hospital of Guangxi Zhuang Autonomous Region from January 2011 to December 2013 were randomly divided into AIT treatment group (30 cases) and control group without AIT (30 cases), all patients were investigated by using Gesell Developmental Scales and the Gross Motor Function Measure (GMFM)-66 before and after 3-month therapy, and the changes in the regional cerebral blood flow of children (rCBF) were detected by single photon emission computed tomography (SPECT) before and after treatment.Results The scores of development quotient (DQ) of the treatment group after the AIT in areas of adaptive behavior, personal-social behavior,language(52.44 ± 13.43,52.07 ± 11.57,57.19 ± 6.18) were higher than those of the control group (45.09 ± 11.02,45.86 ± 9.66,53.44 ± 5.49), and the differences between the 2 groups were greatly significant statistically(t =-2.32,-2.26,-2.49, all P ＜ 0.05).There were no significant difference in DQ of gross motor, fine motor and scores on the GMFM-66 in the treatment group before and after treatment [40.40 ± 8.57,49.50 ± 14.20, (55.81 ±8.72) scores vs 44.03 ±11.90,46.34±9.78,(58.81 ±7.86) scores,t=-1.42,1.08,-0.52,all P＞ 0.05].SPECT detected abnormalities in all patients (100.00％) both in the 2 groups, compared with the control group,the rCBF was improved significantly after treatment in the treatment group (86.67％) (x2 =35.49 ,P ＜ 0.05).Conclusions The treatment of AIT can greatly improve the intelligence, language development and the brain function in children with spastic CP.It is an effective adjutant of rehabilitation method for children with spastic CP to improve intelligence and language development, and has less influence on motor function.

Objective To investigate the therapeutic measures of unresectable primary liver cancer (PLC) with transcatheter arterial chemoembolization(TACE).Methods The clinical data,treatment measures and followed up data of 312 patients with unresectable primary liver cancer from January 1991 to March 2010 were analyzed retrospectively.Of these 312 patients, different dosages, measures of transcatheter arterial chemoembolization together with immunotherapy and nutritional support treatments were given to the patients according to their own statements, including the patency of portal vein (evaluated by portography), the range, blood supply and lipiodol concentration of the lesions (evaluated by hepatic arteriography), and the systemic conditions.Some of these patients also accepted cryotherapy, radio frequency ablation (RFA), percutaneous ethanol injection therapy.Results Two hundred and eighty-seven patients were followed up (92％).Forty-two cases accepted the two-stage operation as the lesions were localized or reduced.In these 42 patients, 34 cases accepted the hepatectomy, 8 cases accepted the cryotherapy.The 1,3 and 5 year survival rate of all patients were 87.6％, 33.1％ and 13.2％.Conclusion TACE for unresectable primary liver cancer should be used individually and comprehensivly.Surgical treatment should be taken once the lesions can be resected.

von Willebrand factor (vWF) and factor Ⅷ (FⅧ) exist in a complex form in blood.After being activated,they mediated platelet adhesion and aggregation,and play an important role in the course of thrombosis.The levels in blood of both of them were affected by a variety of factors.vWF and FⅧ are closely associated with the risk,etiological type,severity and outcome of acute ischemic stroke.Studies on the corresponding antagonistic drugs have made a breakthrough,and these drugs may become more advantageous antithrombotic s.

BACKGROUND: Transplantation of bone marrow mesenchymal stem cells (MSCs) improves functional recovery after spinal cord injury (SCl), but the mechanisms involved remain unclear.OBJECTIVE: To observe the effects of MSCs transplantation on the expression of brain-derived neurotrophic factors (BDNF) in rats after SCl.DESIGN, TIME AND SETTING: Randomized, controlled, animal experiment. The study was performed at the Laboratory of Neuroanatomy, China Medical University from April to July 2003.MATERIALS: A total of 64 SD rats, aged 3 months, of either gender, weighing 250-300 g, were used. Of them, 4 were randomly selected to isolate and culture MSCs, and the remaining were used to establish SCl models.METHODS: The 60 rats were randomly divided into 3 groups. Seven days after SCl, MSCs group (n=24) was transplanted with 5 μL culture solution containing 1×109/L MSCs to the injury site using micro-injection; PBS group (n=24) was transplanted with 5μ L PBS, and the blank control group (n=12) with 5μ L normal saline.MAIN OUTCOME MEASURES: The rats were sacrificed at 7, 14, and 28 days post-surgery. MSCs morphology was observed and the expression of BDNF at the lesion areas was examined by immunohistochemistry,RESULTS: All 60 rats were included in the final analysis. After ten subcultures, the cell proliferative capacity was reduced, and cell body turned to flat; the MSCs protiferation and morphous could be maintained by adding basic fibroblast growth factor.Transplantation of MSCs enhanced the expression of BDNF compared with PBS and blank control groups at 7, 14, and 28 days post-surgery (P ＜ 0.05); white no significant difference was found between PBS and blank control groups (P ＞ 0.05).

Streptolysin S (SLS),one of the important virulence factors of Streptococcus,exist in several kinds of human and animal pathogenic bacterial,including Streptococcus pyogenes,Strepstococcus iniae and Streptococcus anginosus.SLS is a peptide toxin encoded by nine consecutive genes (sagA-sagⅠ).The functions of SLS include contributing pathogenic bacterium to pass through epithelial barrier,causing tissue damage,resisting to phagocytic clearance of host immune cells and interacting with other virulence factors.In addition,SLS as a signaling molecule of cell quorum sensing is involved in regulating the expression with other virulence factors.This paper summarized the structures and the biological functions of SLS in Streptococcus infection.
