OBJECTIVETo determine the recognition of healthy medical students on deqi after acupuncture, reveal the qualitative and quantitative rules of deqi and understand whether these rules are the factors of the clinical application of acupuncture therapy.

METHODSThe class questionnaires were used for the investigation study on the understanding of deqi after acupuncture at Hegu (LI 4) or Zusanli (ST 36) in 86 healthy students in the clinical medicine class.

RESULTS(1) Deqi was a kind of complicated compound feelings, with many sensation qualities such as distending pain, distension and pain. (2) Deqi was a kind of mild and moderate sensations. In 10-score credit sys tem of Massachusetts General Hospital acupuncture sensation scale (MASS), the scores of distending pain (4.69 +/- 2.83), distension (4.39 +/- 2.91) and soreness and distension (3.93 +/- 2.93) were around 5 (moderate degree), the scores of stabbing pain (1.89 +/- 2.02) were around 2 (mild degree). (3) The differences in the quantitative scores were significant for stabbing pain, distending pain, distention, soreness and distention and the others before and after treatment (all P<0.05).

CONCLUSIONDeqi of acupuncture is the mild and moderate complicated sensations manifested as distension, soreness, pain and numbness. As the invasive therapy, the filiform needle puncture will bring a certain psychological impacts on the receptors. The subjective sensation is possibly the factor for the patients' selection of acupuncture treatment.

Background There is multi-dimensional order of spatial stereopsis perception in human,however,current stereopsis examination is zero-order of position disparity.A multi-dimensional space perception model is very important for the detection of stereoacuity.Objective This study was to screen the deficit of zero-order,first-order,second-order multi-dimensional spatial stereopsis perception in amblyopia and strabismus children and to explore the association of zero-order,first-order,second-order spatial perception deficit.Methods Multidimensional spacial perception was examined in 79 children aged 4-14 years in Beijing Children' s Hospital.Nineteen normal children,19 children with ametropia amblyopia,12 children with anisometropic amblyopia,18 children with strabismus and 11 children with strabismus combined amblyopia were included this study.The random-dot and line spatial stereopsis perception in zero-order,first-order and second-order were examined with a new system of multidimensional space perception screening.Written informed consent was obtained from each subject or custodian before any ocular examination associated with this study.Results Absence of zero-order,first-order,second-order random-dot channel was found in 24 children (24/79,30.4％),18 children (18/79,22.8％) and 24 children (24/79,30.4％) respectively,with an average percentage of 27.9％.Absence of zero-order,first-order,second-order line channel was examined in 37 children (37/79,46.8％),37 children (37/79,46.8％),32 children (32/79,40.5％),with an average percentage of 44.7％.In the children with a deficiency of the zero-order spatial perception,the children who still remained the first-order or/and second-order spatial perception of random-dot accounted for 41.6％ and that of lines accounted for 43.2％.In children without deficiency of zero-order random-dot or lines spatial space perception,deficiency of first-order and/or second-order spatial perception was in 37.5％ children.Various order spatial perception deficiency was seen in children suffering from amblyopia or strabismus compared with normal group(P ＜ 0.05).Conclusions There exists spatial perception deficiency in children with amblyopia or strabismus.The patients with zero-order spatial perception absence partially remain a first-order or/and second-order spatial perception;while the patients with normal zero-order spatial perception might have first-order or second-order spatial perception deficiency.The multi-dimensional space perception model has a directive role for the training of visual information process and the treatment of spatial perceptual learning in children with amblyopia or strabismus.

OBJECTIVETo compare the clinical effective differences between acupuncture-moxibustion and Chinese herbs for functional dyspepsia with emotional disorder.

METHODSEighty patients were randomly divided into an observation group and a control group, 40 cases in each one. In the observation group, based on the basic treatment Zusanli (ST 36), Yinlingquan (SP 9), Zhongwan (CV 12), Danzhong (CV 17), Neiguan (PC 6), Taichong (LR 3), Ganshu (BL 18), Geshu (BL 17) and Danshu (BL 19) were selected once every day or every other day. The treatment was given 14 times. In the control group, based on the basic treatment individual therapy of Chinese herbs according to syndrome differentiation was applied,one dose a day. Patients were treated for 4 weeks in the two groups. The scores of self-rating depression scale (SDS), the main symptoms and satisfied degree by self-rating for treatment were observed before and after 4-week treatment in the two groups. Also, the rate and the average time of return visit were compared in 6 months after treatment. Results After treatment, the SDS scores and the main symptoms scores were all improved compared with those before treatment in the two groups (all P< 0. 05). After 4-week treatment, the improvement of the SDS score in the observation group was better than that in the control group (48. 9±8. 5 vs 53. 1±8. 0, P<0. 05). After 1-week treatment and 4-week treatment, the improvements of the main symptoms in the observation group were superior to those in the control group (2. 7 ± 1. 0 vs 3. 3±0. 9, 1. 5±0. 9 vs 2. 3±1. 1, both P<0. 05), and the satisfied degree scores by self-rating were better than those in the control group (3. 0±1. 1 vs 3. 8±1. 3, 2. 0±1. 4 vs 2. 9±1. 5, both P<0. 05). In 6 months after treatment,the return visit rate in the observation group was 42. 5% (17/40), and it was lower than 70. 0% (28/40) in the control group (P<0. 05). The average time of return visit in the observation group was less than that in the control group (1. 0±0.8 vs 1. 9±0. 7, P<0. 05).

CONCLUSIONThe effect of acupuncture-moxibustion or functional dyspepsia with emotional disorder is better than that of Chinese medicine.

AIM: To investigate the effects and mechanism of enalapril on nephritis of diabetic mice. METHODS: Diabetes was induced by injection of streptozotocin after uninephrectomy. Rats were randomly divided into three groups: control, diabetes, diabetes treated with enalapril (10 mg?kg~-1 ?d~-1 by gavage). 8 weeks after STZ injection, urine albumin excretion rate (AER) were measured, and glomerular morphology were observed by light microscopy. The levels of malonyldialdehyde (MDA) in renal tissue and urine as well as activities of superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GSH-PX) in renal tissue were determined. Immunohistochemistry for ED-1 (macrophage marker), monocyte chemoattractant protein-1 (MCP-1) and intercellular adhesion molecule-1 (ICAM-1) were performed by streptavidin-biotin complex (SABC) technique. RESULTS: Increased kidney weight, ratio of kidney weight to body weight, AER and expansion of mesangial as well as tuft areas on histological examination of the kidney were significantly attenuated by the treatment of enalapril (P

0.05). CONCLUSION Obesity was an influential factor of snoring. The PS and OSAHS have the same effect on children growth and their clinical features.

Objective To analyze the expression of molecular biological markers in patients with early stage adenocarcinoma of lung and to determine the correlation between combined expression and prognosis. Methods Pathologic specimens were collected from 68 patients of early stage adenocarcinoma of lung in our hospital between 2000 to 2002. A panel of molecular markers, including Ki-67, Her-2, P16, P53, VEGF, MMP-9 and CD44v6, were chosen for immunohistochemical analysis of the tumor. Cox proportional hazards regression analysis was used to ana-lyze the relationship between expression of these factors and prognosis. Results Muhivariable analysis demonstrated significantly elevated risk for the following molecular markers: P53 (RR=3.228,95.0% CI 1.331-7.828, P=0.010),MMP-9(RR=2.071,95.0% CI 1.062-4.036,P=0.033),VEGF (RR=2.577,95.0% CI 1.124-5.908, P=0.025). The survival period in the patients with combined expression was remarkably shortened. Conclusions Combined evaluation of P53, VEGF and MMP-9 has clinical significance to the prognosis of early stage adenocarcino-ma of lung.

OBJECTIVETo investigate the effect of aurora kinase inhibitor ENMD-2076 on human acute myelogenous leukemia (AML) cell lines.

METHODSAML THP-1 and Kasumi-1 cells were treated with ENMD-2076 for 24 h and 48 h,respectively. Cell growth was measured by MTT assay. Apoptosis was determined using Hoechst staining apoptosis detection kit. Activation of Caspase pathway and expression of apoptosis regulator proteins were detected by Western blot.

RESULTSENMD-2076 significantly induced growth arrest and apoptosis in THP-1 and Kasumi-1 cells. Enhanced apoptosis was observed in ENMD-2076 group evidenced by strong activation of Caspase-9,Caspase-3 and PARP. Furthermore,the ENMD-2076 treatment resulted in down-regulation of anti-apoptotic protein Mcl-1 expression. Also,up-regulated expression of pro-apoptotic protein Bak,Bad and Bax was detected after ENMD-2076 treatment.

CONCLUSIONENMD-2076 can kill effectively AML cells by inhibiting cell growth and inducing apoptosis,which is associated with activation of Caspase pathway and regulation of pro-apoptotic and anti-apoptotic proteins.
