Histamine H 1R antagonists are mainly administered to treat the diseases of hypersensitivity reaction. And histamine H 2R antagonists are mainly administered to treat gastroenteric diseases. But in recent years administered simultaneously H 1R and H 2R antagonists can enhance their effects. Combination of H 1R and H 2R antagonists has good therapeutic effect on hypersensitivity reaction, cancers, asthma, etc, and can eliminate side effects.

OBJECTIVE: To explore the applications of imaging examination on rib fracture sites in forensic identification. METHODS: Features including the sites, numbers of the processed imaging examination and the first radiological technology at diagnosis in 56 cases of rib fractures from 163 injuries were retrospectively analyzed. RESULTS: The detection rate of the rib fractures within 14 days was 65.6%. The initial detection rate of anterior rib fracture proceeded by X-ray was 76.2%, then 90.5% detected at a second time X-ray, while the detection rate of CT was 66.7% and 80.0%, respectively. The initial detec- tion rate of rib fracture in axillary section proceeded by X-ray was 27.6%, then 58.6% detected at a second time X-ray, while the detection rate of CT was 54.3% and 80.4%, respectively. The initial detection rate of posterior rib fracture proceeded by X-ray was 63.6%, then 81.8% detected at a second time X-ray, while the detection rate of CT was 50.0% and 70.0%, respectively. CONCLUSION It is important to pay attention to the use of combined imaging examinations and the follow-up results. In the cases of suspicious for rib fracture in axillary section, CT examination is suggested in such false X-ray negative cases.

Objective Evaluate the immunotoxicity of Ginenoside Compound K Injection.Methods Active Systemic Anaphylaxis (ASA)tests and Passive Cutaneous Anaphylaxis (PCA)tests were used to evaluate Ginenoside Compound K Injection.Results In the ASA tests,positive control group showed pole-strength anapbylaxis,both the high-dose group and the low-dose group of Ginenoside Compound K Injection didn't produce allergic reaction and the body weights of all groups showed no significant differences.In the PCA tests,all rats of positive control group caused blue spots with their diameters bigger than 5 mm (diameters on the left side of blue spots was (10.1± 3.34) mm and diameters on the right side of blue spots was(7.57± 1.94)mm.Serum IgE was significantly increased.While both high dose and low dose of Ginenoside Compound K Injection group didn't show blue spots with their diameters greater than 5 mm and their IgE levels showed no significant differences compared with negative control group.Conclusion Ginenoside Compound K Injection showed no immunotoxicity under these experimental conditions.

Objectives To observe the expression of death receptor 6 (DR6) in neonatal rats with hypoxia-ischemia brain damage (HIBD). Methods HIBD was induced in day 7 rats. The expression of DR6 at 24 h, 72 h and 7 d after HIBD and the expression of Caspase-3 at 24 h were evaluated by immunostaining. The injury of neural cells was evaluated by cresyl violet at 7 d after HIBD. The cognitive function was evaluated by T-maze test at 60 d after HIBD. Results DR6 positive cells were the most abundant in the ipsilateral cortex at 24 h after HIBD, and decreased gradually at 72 h and 7 d after HIBD. There was signiifcant difference of the expression of DR6 among different time points in HIBD group (P<0.01). Compared with control group, DR6 positive cells were more abundant in the ipsilateral cortex at 24 h and 72 h after HIBD (P<0.01) and caspase-3 positive cells were more abundant in the ipsilateral cortex at 24 h after HIBD (P<0.05). The number of cortical neurons were decreased at 7 d after HIBD as compared with control group (P<0.05). The T-maze test showed there was decline of the cognition in HIBD group com-pared with control group (P<0.05). Conclusions The DR6 signaling pathway plays an important role in cerebral cortex injury which may lead to the subsequent neurofunctional deifcits in neonatal HIBD rats.

Objective To evaluate the effects of traditional Chinese medicine likeDansen and western medicine in treating traumatic brain edema (TBE). Methods A total of 130 Wistar rats were divided randomly into six groups: Group A (normal contrast group), Group B (operation group), Group C (western medicine treatment group, WM group), Group D (western medicine and salvia injection), Group E (western medicine and Honghua injection) and Group F (western medicine and Sanqi injection). The model of brain edema was established by liquid nitrogen treatment to assay whole blood viscosity, water content and Even blues (EB) in brain tissues and to observe the content and pathologic changes of endothlin (ET) in plasma. Results Whole blood viscosity of Groups D, E and F was lower than that of Group B (P0.05). Water content and EB in brain tissues and ET of plasma in Groups C, D, E and F were lower significantly than those in Group B (P
