This study aims to explore and analyze the condition of concurrent diseases and medicine use of traditional Chinese medicine (TCM) and western medicine among the patients with insomnia. One thousand and sxity seven cases of data from 20 national hospitals' hospital information system (HIS) databases were collected. The frequent concurrent diseases included hypertension (26.9%), brain blood supply insufficiency (24.93%), cerebral infarction (19.49%), blood lipoprotein disturbance (15.28%), coronary heart disease (14.15%), headache (10.68%), chronic gastritis (8.81%), type 2 diabetes mellitus (7.87%), depressive disorder (7.4%) and anxiety disorder (6.65%). The 10 most frequently-used western drugs included alprazolam (35.99%), aspirin (25.4%), olanzapine (24.18%), cinepazide (23.06%), flupentixol & melitracen (18.74%), zolpidem (18.37%), oxiracetam (15.65%), estazolam (15%), aniracetam (13.4%) and piracetam (13.31%). The 10 most frequently-used TCM included Shuxuening injection (16.4%), Shuxuetong injection (15.18%), extract of ginkgo biloba leaf (14.71%), gastrodin (12.46%), Dengzanxixin injection (11.34%), Xueshuantong (8.53%), Danhong injection (6.37%), compound liquorice tablet (5.81%), Sanqi Tongshu capsule (5.72%) and sowthistle-leaf ixeridium injection (5.34%). Among all combined uses, the most frequent western drug use was alprazolam and olanzapine, while combined use of hypnotic drug and Huoxuehuayu formula is the most frequent. This study concludes that the concurrent diseases mainly include cardio-cerebrovascular diseases, metabolic disorders and anxiety-depression disorders, with increasing tendency of diseases types by ages, especially for cardio-cerebrovascular diseases. The most frequently-used hypnotic is alprazolam in the insomnia patients, and it is worth being concerned about the off-label use of olanzapine as an antipsychotic for the treatment of insomnia However, due to the fact that all cases data are from the inpatients, these findings have some limitations.

Objective To investigate the mechanism of the inhibitory effect of ?-ray irradiation on rat vascular smooth muscle cells(VSMC). Methods The ef fect of ?-ray irradiation on proliferation of VSMC was observed by 3?H-TdR incor poration. After ?-ray irradiation, the VSMC cell cycle change was detected b y flo w cytometry. The expression of p53, cyclin D and PCNA was investigated by Wester n Blot. Results The inhibitory effect of ?-ray irradiation on VSMC proliferati on was dose-dependent. After ?-ray irradiation, VSMC was arrested in G 1 st age, w ith the expression of p53 increased but the expression of cyclin D and PCNA decr eased. Conclusions ?-ray irradiation can inhibit the proliferation of VSMC. T he main mechanism is probably due to the induction of cell cycle arrest and inhi bition of the VSMC mitosis ,during which process, p53,cyclin D and PCNA all pla y an important role .

In this paper, three kinds of chemotactic parameters (concentration, temperature and pH) were determined by plate assay and spore germination method to research the chemotactic response of Botrytis cinerea and Alternaria panax, and their spores on total ginsenosides. The results showed that Botrytis cinerea had strong chemotactic response at the mid-concentration of total ginsenosides (cultivation temperature was 20 degrees C and pH value was 6), and the data of chemotactic migration index (CMI) was 1.293 0, chemotactic growth rate (CGR) was 0.476 0, spore germination rate (SGR) was 53%, and dry weight of mycelial (DWM) was 0.452 6 g x L(-1); however, Alternaria panax had strong chemotactic response at the low-concentration of total ginsenosides (cultivation temperature was 25 degrees C and pH value was 6), and the data of chemotactic migration index (CMI) was 1.235 4, chemotactic growth rate (CGR) was 0.537 0, spore germination rate (SGR) was 67%, and dry weight of mycelial (DWM) was 0.494 8 g x L(-1). The results indicated that the low and middle concentration (2, 20 mg x L(-1)) of total ginsenosides had significant promoting effect on chemotactic response of these two pathogens, and the spore germination, mycelial growth rate, dry weight of mycelial of them were also significantly improved by this chemotactic response, whereas it decreased as the increase of total ginsenosides concentration.

4.Characteristics of subthalamic neuronal activities in Parkinson's disease.
Acta Physiologica Sinica 2003;55(4):435-441
The relationship between neuronal activity in subthalamic nucleus (STN) and parkinsonian symptoms was investigated. Thirty-five patients with idiopathic Parkinson's disease (PD) received stereotactic surgical treatment. Microelectrode recording in STN and electromyography (EMG) on the limb contralateral to the surgical side were employed intraoperatively. Single unit firings discriminated from multiple neuronal discharges were recorded, and the correlation between neuronal activity and limb EMG was analyzed. The results showed that there were distinguished characteristics of neuronal discharges in STN and its surrounding areas. Of 346 STN neurons recorded from 36 microrecording trajectories in 35 patients, three patterns of neuronal activities were identified: irregular bursting pattern with a mean frequency of 43.0+/-11.2 Hz (56%, n=244); tonic firing pattern with a mean firing frequency of 41.0+/-12.0 Hz (15%, n=66); and regular bursting pattern with a mean frequency of 47.0+/-11.7 Hz (29%, n=126). The rhythm of regular bursting with the frequency ranging from 3.8 to 6.0 Hz was highly correlated with the frequency of limb tremor measured by EMG (r(2)=0.66, P<0.01). These cells were therefore called tremor-related neurons or tremor cells. In particular, 80% tremor cells were located in the medio-superior part of STN. In conclusion, our results suggest that microelectrode recording is a critical technique for electrophysiological localization of the target in treating PD. The tremor-related neuronal activity and movement-related neuronal activity recorded from STN are responsible for the clinical parkinsonian symptoms, suggesting that STN plays an important role in the pathophysiology of PD.

An expression plasmid carrying anthrax protective antigen (PA) gene was constructed, which has an OmpA signal sequence attached to the 5' end of PA gene. The plasmid was transformed into E. coli and induced to express recombinant PA (rPA) . The recombinant protein, about 10% of the total bacterial protein in volume, was secreted to the periplasmic space of the cell. After a purification procedure including ion-exchange, hydrophobic interaction chromatography, and gel filtration, about 15 mg of 95 % pure rPA was obtained from 1-liter culture. The bioactivity of rPA was proved by in vitro cytotoxicity assay. The polyclonal antiserum from rabbits immunized with rPA could inhibit the action of anthrax lethal toxin in vitro, which suggests that antibodies against rPA can provide high passive protection against anthrax. The results reported here may be helpful to develop a safe and efficacious recombinant PA vaccine against anthrax.

The aim of this study was to investigate the growth, immunophenotype and interleukin-6 (IL-6) level of bone marrow stromal cells (BMSC) in patients with acute leukemia (AL) and multiple myeloma (MM). BMSC was cultured by wall-adhesion method and the growth of BMSC was observed. The immunophenotype and cell cycle of BMSC were detected by flow cytometry. The level of interleukin 6 (IL-6) in BMSC culture system was detected by ELISA. The results showed that the primary (17.3 +/- 7.8 days) and continuous (10.3 +/- 3.5 days) growth cycle of BMSC in patients with AL were significantly shorter than those in patients with MM (26.5 +/- 6.3 and 16.5 +/- 4.1 days respectively), and shorter than those in normal controls (25.8 +/- 6.3 and 17.5 +/- 2.4 days) respectively. Similarly, S + G2% (17.4 +/- 3.6%) of BMSC in patients with AL was significantly higher than those in patients with MM (8.5 +/- 2.2%) and in normal controls (8.9 +/- 2.3%). All of the three groups showed positive antigen expressions with CD29 and CD44 were 100%, while CD138, CD34, CD54, CD56 positive were not expressed and CD106 was partially expressed positive. The supernatant IL-6 level of BMSC system in MM patients (1288.5 +/- 736.7 pg/ml) was significantly higher than those in AL patients (859.3 +/- 203.1 pg/ml) and normal controls (850.9 +/- 129.5 pg/ml). It is concluded that the growth, S + G2% of cell cycle and IL-6 level of BMSC in patients with MM, AL and normal control are significantly different, whereas the antigen expressions are similar.

OBJECTIVEOccult hepatitis B infection of voluntary blood donors has been plagued in the serum screening. Determined the OBI through the highly sensitive detection methods Nest-PCR among the blood donors, and then learned occult HBV infection and analysed the genotypes of this area.
METHODS10 080 serums of donors were determined respectively by the imported Abbott HBsAg kit and Beijing Wantai anti-HBc and anti-HBs reagents, obtained the gene and detected DNA sequences by the high sensitive Nest-PCR method.
RESULTSAmong 10 080 cases of unpaid blood donors, 108 cases were detected HBsAg positively by Abbott sensitivity kit (positive rate of 1.07%), 767 cases were anti-HBc single - positive (positive rate of 7.67%). 25 patients screened blood donors who tested negative for serum HBsAg and positive for HBV DNA in the 10 080 cases. Occult HBV infection incidence rate was 0.25%. 12 cases were HBV genotype C (48%), 13 cases were genotype B (52%), and no other genotypes. Genotype B has no statistically significant difference to genotype C (P > 0.05). Sequence analysis showed that 5 patients in the HBsAg epitope "a" (aa124 - aa147) have mutation (20%).
CONCLUSIONThe high proportion of occult hepatitis B infected among voluntary blood donors in our country. Also genotype and mutation was differences in different regions.

OBJECTIVETo investigate the relationship between limb tremor and neuronal firing in thalamus (Vim) and retrospectively review the clinical effects and safety of the surgical treatment of essential tremor (ET).
METHODSForty-two ET patients received microelectrode-guided thalamotomy and 11 cases were quantitatively evaluated with FAHN rating scales pre- and post-operatively.
RESULTSThere were electrophysiological tremor-related neurons in ventrolateral part of thalamus. Lesioning of those neurons abolished contralateral limb tremor in all of the patients. No permanent contralateral weakness, dysarthria and hemorrhage were observed.
CONCLUSION"Tremor cell" in thalamus plays a key role in the symptom of ET patients. Destruction of those cells may completely and permanently abolish tremor symptom.
