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 investigate whether emergency rooms in major general public hospitals are reasonably designed and convenient for patients. Methods 78 major public hospitals were selected from all over China, except Hong Kong, Macau and Taiwan, for emergency room convenience analysis. The standards in use were the "Standards of Hospitals" of Joint commission International Accreditation. Results The investigation found in such hospitals the following: poor road conditions outside the clinic and insufficient guides in the clinic; long-than-expected distance (normally over 50 meters) from ER to imaging departments (such as X-ray and CT scan service); ERs in provincial capital cities are significantly more convenient than those in non-capital cities; distance from ERs to CT service is significantly shorter in hospitals in eastern China than those middle and western China. Conclusions Parameters on ER's service quality from "Standards of Hospitals" could serve as a guideline to emergency medicine in China. ERs in China need to improve with conspicuous ER signs, unblocked passageways, and convenient access to inspection departments.

Objective To explore the abnormal inflammatory cytokine profile of salpingitic infertility by means of cytometric bead assay(CBA). Methods To assay representative inflammatory cytokines of 40 patients of salpingitic infertility(PSI) and 40 healthy control by CBA, and compared 30 samples of serum with peritoneal fluid collected from identical subject. Results Experiment data displayed that in PSI the Th lymphocytes were decreased significantly (t =2. 1236,P <0. 05), Ts lymphocytes increased markedly, and the ratio of Th/Ts markedly decreased ( t = 2. 8392, P < 0. 01 ), compared with those of healthy control.(Pre-)inflammatory eytokines (IL-8, IL-1β, IL-6 and TNF-α) were all significantly higher than those of healthy controls ( t = 4. 9302,5. 5449,3. 4975,5. 6623, respectively, all P < 0. 01 ) ; while anti-inflammatory cytokines ( IL-10, IL-12 ), also increased markedly ( t = 5. 3428,5.9847, respectively, all P < 0. 01 ).Beside IL-10, all other cytokine concentrations presented in serum were higher than that of peritoneal fluid;IL-8(t =2.2113,P <0.05),IL-llS(t =2.9756,P <0.01), IL-6(t =2.3298,P <0.05), TNF-α (t =3. 2895, P < 0. 05 ), IL-12 ( t = 3. 3281, P < 0. 05 ), implying more sensitive of serum samples. Conclusion PSI displayed extensive disorders of the inflammatory cytokine network, CBA can be used to probe the disharmony condition at high through-out and high sensitivity.

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.

Objective To explore the role of CGRP and progesterone along with it on the etiopathology of PIH. Methods 8 specimens of umbilical vein endothelial cells from women with PIH were cultured. Four groups were divided when cultured cells were confluent: the sera of normal pregnancy women (group 1), the sera of women with PIH (group2), the mixture of the sera of women with PIH and the injection of progesterone (group3), and the same amount of media (group 4). The cultured cell were added respectively into the four different kinds of media. After 24h of incubation, the concentration of endothelin (ET) and CGRP in media were measured by radioimmunoassay. Results 1. Comparing with group1, the concentration of CGRP in group 2 decreased and ET increased significantly. Statistic difference of ET/CGRP was found between the two groups. 2. Comparing with group 1, the concentration of CGRP in group 3 was unchanged and ET increased obviously. No difference of ET/CGRP was shown between them. 3. Comparing with group 3, in group 2, the concentration of CGRP decreased obviously and that of ET unchanged. Significant difference of ET/CGRP was found. Conclusions Progesterone, along with CGRP, might delay the onset and progressing of PIH.

AIM: To study the expression and change of growth hormone receptors in experimental cirrhotic liver in rats. METHODS: Thioacetamide-induced liver cirrhosis was developed in Sprague-Dawley rats. The expression of growth hormone receptor and its mRNA was investigated by radio-ligand binding assay, revere transcript-polymerase chain reaction (RT-PCR) and digital image analysis in liver tissue or hepatocytes taken from normal control or cirrhotic rats with different stages of cirrhosis. RESULTS: Growth hormone-specific singular binding sties, namely growth hormone receptors, were detected in liver tissue or hepatocytes from rat samples with cirrhosis. The binding capacity of growth hormone receptors in rat cirrhotic live tissue was significant lower than that in normal control, and it decreased gradually along with the accumulation of collagen in the process of formation and development of liver cirrhosis. The binding sites of growth hormone receptors in rat cirrhotic liver cells were significantly lower than that in normal control. The expression of growth hormone receptor mRNA in rat cirrhotic liver tissue was also significant lower than that in normal control. CONCLUSIONS: The growth hormone receptor was expressed in cirrhotic livers at a reduced level in isolated hepatocytes or live tissue of cirrhotic rats, and lesser expression of growth hormone receptors was found in later stage of cirrhosis. The suppressed expression of growth hormone receptor was partly due to the reduced expression of its mRNA in cirrhotic liver tissue.

Objective To study the efficacy and toxicity of standard CEOP regimen in elderly patients with non-Hodgkin's lymphoma (NHL).Methods The study included 34 previously untreated patients,age 60 to 80 years old,with NHL,through July 2009 to December 2011.The patients with T-cell lyphoma received four to eight cycles of CEOP (cyclophosphamide 750 mg/m2 d1,epirubicin hydrochloride 60-75 mg/m2 d1,vincristine 2mg d1,and dexamethasone 10-15 mg d1-5) every 3-4 weeks.Otherwise,the patient with B-cell lymphoma received R-CEOP,rituximab (375 mg/m2) was administered one day before CEOP.All the patients' clinical materials were collected and used to annalyze the efficacy and toxicity of the CEOP±R regimen.Results Among these 34 NHL patients,17 cases reached CR,9 cases reached PR,3 cases remained SD,and 5 cases appeared PD.The total response rate was 76.5 ％(26/34).The major toxicity was bone marrow restraint.The rate of leukocyte decline with Ⅲ-Ⅳ degree was 71.4 ％ (24/34).Conclusion Using the standard regimen of CEOP leads to satisfied efficacy of elderly patients with NHL,and the toxcity is tolerant.

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.
