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 To have a general picture the history and existing problems of independent clinical labs in China, for the purpose of building a supervision mechanism for such novel clinical institutions-clinical labs. Methods By way of the nationwide network of clinical labs, ICLs in China were surveyed with written questionnaires and field check. Results ICLs have grown into a greater and diversified scale thanks to the development of China's economy and laboratory technology. However,such vulnerabilities as unbalanced staff ratio, full-range quality control bugs, cutthroat competition,asymmetrical information disclosure, and bio-safety have loomed large in the meantime. Conclsion It is time to formulate a stricter industry access system and appropriate regulatory modes; ICLs should take a good care of the "Four relations" in their development, and health regulators should play a tighter role in the "Four supervisions". All these aim at better sharing medical resources, and building a win-win environment for the people, hospitals and ICLs.

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 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.

Objective To study the demographics and background of attempted suicide individuals,such as age,gender,mode of suicide,seasonality,etc.so as to improve prevention strategy.Methods By sequential sampling analysis,there were data of 895 survivors from committed suicide taken from 907 attempted suicide individuals recorded in an emergency room of a local hospital between 2002 and 2008 for retrospectively study.Results The sample was composed of 191 males and 704 females with a male to female ratio of 1∶3.69.The adolescents and young adults aged 15-34 years accounted for the vast majority of attempted suicide individuals with the peak at the age of 24 years.The number of committed suicide remarkably reduced after the age of 47 years.The major mode of committed suicide was ingestion of poisons.The incidence of committed suicide declined significantly from 2002 to 2005,and then increased between 2005 and 2008.It was more often occurred in the seasons of Spring and Summer. Conclusions Age,gender,and seasonality are associated with attempted suicide in china,and these risk faetors should be the focuses of suicide prevention in China.Additionally,control of pesticides and psychological intervention should be the parts of the work to prevent suicide in the this cohort of special individuals with propensity of committed suicide.

Objective:To study the role of angiopoietin-2(Ang-2) in angiogenesis in oral squamous cell cacinoma(OSCC). Methods:Expression of angiopoietin-2 and CD_34 in 41 cases of OSCC(13 cases with lymph node metastasis)and 10 cases of normal oral mucosa was detected by immunohistochemical SABC method. Microvessel density(MVD) in the samples was counted under microscope. Results:Ang-2 was detected in 28 out of 41(68.29%) cases of OSCC and 2 out of 10(20%) of normal oral mucosa(P
