Abstract
Objective:To explore the clinical characteristics and treatments of patients with idiopathic sudden sensorineural hearing loss(ISSHL) with or without vertigo. Method:One hundred and twenty ISSHL cases were divided into vertigo group (n=36) , without vertigo group (n=84) , and with benign paroxysmal positional vertigo group (n=15). All patients were in regular treatment. Besides, according to the types of BPPV, patients do the Epley maneuver or Barbecue roll maneuver. We summarized the result and treatment of the patients. Result:The audiometric curve of ISSHL with vertigo were mainly at flat type. After treatment of the ISSHL patients were better than the patients with vertigo in the degrees of hearing loss . Furthermore, the rate of the patients of marked efficiency, efficiency and total efficiency of ISSHL was lower than the ones without.The patients with BPPV, including 12 cases of posterior semicircular canal and the 3 cases of lateral semicircular canal, were all ipsilateral. Conclusion:ISSHL with vertigo group lost hearing is severer than ISSHL without vertigo. Thus the hearing and the treatment effect were worse.The symptoms without vertigo in ISSHL were better than the patients with vertigo.

Abstract
Objective. To investigate the preventive and theralseutive (therapeutic) effects of basic fibroblast growth factor (bFGF) and Radix Salviae Miltiorrhizae (RSM) on brain injury caused by repeated +Gz exposures. Method. bFGF and RSM were injected intraperitoneally into SD rats before and after repeated +Gz exposures. The contents of excitatory amino acids (EAAs), nitric oxide (NO) and the number of cell apoptosis in the brain were measured, and were compared to those of the control group and normal saline (NS) group. Result. The contents of EAAs, NO and the number of cell apoptosis were significantly higher in repeated +Gz exposures group than those in control group. The values were markedly lower in bFGF and RSM group than those in repeated +Gz exposures group and NS group. Conclusion. bFGF and RSM showed distinct preventive and therapeutic effect on the brain injury induced by repeated +Gz exposures.

[Changes of mRNA expression of IL-1beta and TNF-alpha in rat brains after repeated exposures to +Gz]. HANG TIAN YI XUE YU YI XUE GONG CHENG = SPACE MEDICINE & MEDICAL ENGINEERING 2000; 13:371-3.

Abstract
Objective. To study changes of mRNA expression of IL-1beta and TNF-alpha in rat brains after repeated exposures to +Gz. Method. Twenty conscious SD rats served as the subjects. They were randomly divided into 5 groups. Using an animal centrifuge, control rats (n = 4) were exposed to +1 Gz and experimental rats (n = 16) were exposed to +14 Gz three times, each for 45 s with 30 min interval in between. The rat brains were taken 30 min, 6 h, 24 h and 48 h after the last centrifuge run and total RNA was isolated. mRNA expression levels of IL-1beta and TNF-alpha in rat brain were measured by semi-quantitative reverse transcription polymerase chain reaction (RT-PCR). Result. mRNA expression levels of IL-1beta and TNF-alpha in rat brains taken 30 min, 6 h and 24 h after repeated +Gz exposures were significantly higher than those in control rats, but returned to normal after 48 h. Conclusion. It suggested that mRNA expressions of IL-1beta and TNF-alpha in rat brains can be stimulated by repeated +Gz exposures and the increased expression of IL-1beta and TNF-alpha may play a role in the pathologic course of brain damage induced by +Gz exposures, but the damage is reversible.

Abstract
Objective. To investigate the role of apoptosis in mechanisms of brain damage induced by +Gz exposures. Method. Twenty conscious SD rats were randomly divided into 5 groups. Rats in the control group (n=4) were exposed to +1 Gz and rats in the 4 experimental groups (n=16) were exposed to +14 Gz for three times, each for 45 seconds with 30 min interval in between. All the +Gz exposured were on an animal centrifuge. The rat brains were taken 30 min, 6 h, 24 h and 48 h after the last centrifuge run and fixed and embedded. The apoptosis and expression changes of related gene bcl-2 and p53 were detected by terminal deoxynucleotide (correction of deoxynuleotide) transferase-mediated dUTP nick end labeling (TUNEL) technique and immunohistochemical method, respectively. Result. Apoptotic cells and expression changes of bcl-2 and p53 were observed in CA1 subregion of rat hippocampus taken 6 h after repeated +Gz exposures, but returned to normal after 24-48 h. Conclusion. It suggests that apoptosis and expression changes of bcl-2 and p53 in rats hippocampus can be induced by repeated +Gz exposures and the apoptosis is one of the molecular mechanisms of brain damage induced by repeated +Gz exposures.

Purification and properties of acetylcholinesterase from human brain. SCIENCE IN CHINA. SERIES B, CHEMISTRY, LIFE SCIENCES & EARTH SCIENCES 1993; 36:1207-15.

Abstract
Acetylcholinesterase from human caudate nucleus and partial thalamus was purified by using Con A-Sepharose, short-arm and long-arm ligand Sepharose affinity chromatographies. SDS-PAGE of the purified AChE under the reduced condition showed one main band, corresponding to a molecular weight of 66 kD. The purified AChE with a specific activity of 3384 U/mg protein represented 20% activity of the homogenate supernatant. Analysis of purified AChE by gradient slab PAGE and DISC-PAGE with activity staining revealed the existence of monomer, dimer, tetramer, hexamer and octomer of the enzyme. The isoelectric point of AChE ranged between pH 5.6 and 6.0. Con A-Sepharose affinity chromatography retained most of the applied AChE activity implying that the enzyme is a kind of glycoprotein. The isolated human brain AChE had no cross-immunoreactivity with 3F3 and weak cross-immunoreactivity with 2G8 and 1H11 anti-Torpedo AChE antibodies. Balb/c mice were immunized with human cerebellum AChE purified with Con A and short-arm ligand affinity chromatographies. The antiserum produced showed strong cross-immunoreactivity with Torpedo AChE but weak cross-immunoreactivity with human RBC membrane AChE. The purified human brain striatum AChE was reduced and alkylated, and then hydrolyzed by immobilized TPCK-treated trypsin. Trypsin peptides in the hydrolysate was separated by RP-HPLC. Several large peptide peaks and numbers of small peaks were observed. The large peaks showed obvious immunoreactivity with the mouse anti human cerebellum AChE antiserum.
