Objective： To investigate the modification of GABAA receptor subunits in audiogenic seizure rat cortex and hippocampus when rendered tolerant to flurazepam. Methods： Rats were administrated with flurazepam for two weeks, which resulted in tolerance to flurazepam, in the absence of behavioral signs of withdrawal. GABAA receptor subunits α1, α3, α5, γ2L and γ2S were assayed using quantitative competitive RT-PCR in rat frontparietal motor(FrPaM) and hippocampus. Results： In FrPaM, the contents of mRNA encoding for α1, α3,　γ2L and γ2S were all significantly decreased (24%,17%,35% and 45% respectively),whereas that of α5 was significantly increased (33%) compared with the control. In hippocampus, α1, γ2L, and γ2S mRNA contents were significantly decreased (33%, 35%and 27% respectively). Conclusion： The accomodated change in GABAA receptor subunits α1, α3, α5,γ2L and γ2S in FrPaM and hippocampus may be associated with the mechanism of flurazepam tolerance in audiogenic seizure rats.

AIM To investigate the modification of GABA A receptor subunits in audiogenic seizure rat cortex and hippocampus when rendered tolerant to clobazam. METHODS Rats were administrated with clobazam for two weeks, resulting in tolerance to clobazam. GABA A receptor subunit ?1, ?3, ?5, ?2L and ?2S were assayed using quantitative competitive RT PCR in rat FrPaM and hippocampus. RESULTS In FrPaM,the content of mRNA encoding for ?1,?2L and ?2S were all significantly decreased (27%,43% and 37% respectively),whereas that of ?5 was significantly increased (73%) compared with the control. In hippocampus, ?1, ?2L, and ?2S mRNA content was significantly decreased (28%, 32% and 31% respectively). CONCLUSION The accomodated change in GABA A receptor subunit ?1, ?5,?2L and ?2S in FrPaM and hippocampus may be associated with the mechanism for tolerance to clobazam in audiogenic seizure rat.

Based on introducing digital certificate related concepts, the paper compares the similarities and differences of digital sig-nature soft and hard certificates from the aspects of implementation process, implementation condition, convenience, security, law validi-ty, maintainability, etc.Combining with the actual status of information system, it analyzes the selection of digital signature.

OBJECTIVETo investigate the epidemiological characteristics, clinical manifestations, diagnosis, and treatment of Brucella orchitis, so as to provide reliable evidence for the prevention and treatment of the disease.

METHODSWe conducted retrospective statistical analyses on the medical records of 48 outpatients and 21 inpatients with Brucella orchitis.

RESULTSBrucella orchitis was diagnosed in 6.67% of the male patients with brucellosis (69/1 034). The disease exhibited typical epidemiological features, with a higher incidence rate among those in frequent contact with sheep and elderly people, in the period from April to July, and in the areas with sheep husbandry. All the Brucella orchitis patients had such local symptoms as testicular pain and swelling, more frequently involving both testes, and other most common symptoms included fever, chills, sweating, and painful joints. Based on IIEF-5, 45 of the patients suffered from severe erectile dysfunction, with their reproductive function temporarily affected in the course of the disease. Misdiagnosis easily occurred in the early stage of the disease. Therapeutic options mainly included doxycycline hydrochloride and rifampicin, administered orally or intravenously, which could effect a cure, though relapse might occur in some cases.

CONCLUSIONBru- cella orchitis has distinct epidemiological characteristics, with clinical manifestations of testicular pain and swelling. Though a transient disease, it affects the reproductive function of the patient before cured. It can be treated by combined oral and intravenous medication, with painkillers or ice bags for testicular pain and swelling.

Objective To explore the relationship between predictable ocular motor control and cognitive function in Parkinson's disease(PD). Methods Videonystagmography was used to examine 24 patients with idiopathic PD(PD group) and 24 healthy controls(control group) on predictable ocular motor control.The accuracies of saccade were compared between two groups.The correlation among accuracy for predictive saccade(latency

BACKGROUND:As mechanical load-bearing tissues, tendons have unique biomechanical characteristics. Mechanical loading is necessary in tendon development, and the tendon can alter its structure and biological behaviors in response to the various mechanical loading conditions. OBJECTIVE: To fuly understand the healing process and biomechanical properties of the damaged tendon so as to know the researching progress in the role of stress in the tendon healing process. METHODS: An electronic search of Chinese Biomedical Literature Database and PubMed databases was done for colection of reviews and papers addressing stress effects on tendon healing, and then we analyzed the role of stress in the healing process of tendon from the micro and macro levels. RESULTS AND CONCLUSION:Totaly 59 relevant articles were enroled. Tendon is sensitive to stress, and it can change its structure and biological reaction in response to different stress loadings. Proper stress stimulus to the tendon is necessary to the tendon development and healing. How to achieve a good balance between the lowest (resulting in alienation effect) and the highest stress loadings (resulting in minimaly invasive injury) during the clinical tendon healing is a chalenge. At present the treatment of tendon injuries is stil a huge chalenge to clinicians, and the vast majority of tendon injuries belong to tissue healing.
