1.Research progress of combination application of H_1R and H_2R antagonists
Chinese Pharmacological Bulletin 1986;0(06):-
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.
2.Analysis of 163 rib fractures by imaging examination.
Journal of Forensic Medicine 2014;30(6):460-462
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 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 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 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.

Objective To study the method for distinguishing the crude and processed Radix of Polygonum multiflorum Thunb. by TLC. Methods Some of the samples were collected from different cities in China, some of them were prepared following the pharmacopoeia standard or local standard. TLC conditions: 5-hydroxymethyl-furfural (5-HMF) was used as a standard matter with the developing solvent of petroleum ether (60~90 ℃)-ethyl acetate (1∶1) on a silica G thin layer plate, sprayed with 15% ?-naphthol in ethanol solvent, heated and detected in daylight. Results TLC chromatogram showed that crude and processed product of Polygonum multiflorum Thunb. were different. Conclusion TLC method for distinguishing the crude and processed Polygonum multiflorum Thunb. was established.

Objective To prepare huperzine A-carrier protein conjugate and determine its immunogenicity for later production of monoclonal antibody against HupA and establishing an enzyme-linked immunosorbent assay ( ELISA) -based detection method for HupA. Methods HupA was conjugated with bovine serum albumin ( BSA) using glutaraldehyde ( GA) method to obtain the HupA-GA-BSA conjugate,and the hapten number in the conjugate was determined by matrix-assisted laser absorption ionization time-of-flight mass spectrometry ( MALDI-TOF-MS) . BALB /c mice were immunized with HupA-GA-BSA to prepare the antiserum against HupA. The serum titer and specificity of the HupA antibodies were detected by indirect ELISA and competitive ELISA,respectively. Results The conjugation ratio of HupA and the carrier protein BSA was 8∶ 1. The antiserum against HupA with a titer of 1∶ 62 500 was obtained after immunizing the mice with the conjugate,and the antiserum reacted specifically to HupA. Conclusion The synthesized HupA-GA-BSA conjugate possesses good immunogenicity in mice,suggesting the feasibility of preparing the monoclonal antibody against HupA using this conjugate.
