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.

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.
