Objective To explore the clinical factors on the functional recovery of spinal cord cavernous hemangioma operation. Methods Fifty cases patients with complete spinal cord cavernous hemangioma were retrospectively analyzed their clinical data and its influence on prognosis of 2 years. Single factor and multiple factors analysis were performed. Results Compared with the preoperative stage,the grade of Aminoff-Logue score of 28 cases(50. 9%)had improved at least one grade,14 cases(25. 5%)patients with no significant changes and 13 cases(23. 6%)with decreased one grade at least. Logistic regression model showed that patients with clinical types(OR=3. 27,95%CI 2. 34-15. 83,P=0. 006),the time of the attacks to the surgery(OR=2. 93,95%CI 1. 41-10. 61,P=0. 012),and the attacks to the operation time( OR=4. 31,95%CI 2. 46 -12. 32,P = 0. 019 ) were related to neurological function recovery of spinal cord cavernous hemangiomas. Conclusion For patients with SCH dysfunction,regardless of what kind of clinical types of neurological dysfunction extent,should receive surgical treatment to improve neurological function recovery rate as soon as possible.

The expression of CD(8) (+)CD(25) (+)FoxP(3) (+) regulatory T cells (CD(8) (+)Tregs) in the peripheral blood of patients with stable chronic obstructive pulmonary disease (COPD), and the effect of muscarinic cholinergic receptor antagonist tiotropium bromide on the expression of CD(8) (+)Tregs were investigated. Twenty-three patients with moderate to severe stable COPD were enrolled in this study. All patients inhaled tiotropium bromide (18 μg daily) for 3 months. Before and after inhalation of tiotropium bromide, peripheral blood samples were collected from the patients, and T cells were labeled by three-color labeled monoclonal antibodies. Flow cytometry was used to detect the quantity and percentage of CD(8) (+)T cells, CD(8) (+)CD(25) (+)T cells, CD(8) (+)Tregs, CD(4) (+)T cells, CD(4) (+)CD(25) (+)T cells and CD(4) (+)CD(25) (+)FoxP(3) (+) regulatory T cells (CD(4) (+)Tregs) respectively. The percentage of CD(4) (+)T cells was increased from (27.82±2.18)% to (35.53±1.3)% (t=3.20, P=0.004) in the peripheral blood of patients with stable COPD after inhalation of tiotropium bromide for 3 months, that of CD(4) (+)CD(25) (+)T cells was decreased from (10.03 ±1.42)% to (4.21 ±0.65)% (t=3.78, P=0.001), and that of CD(8) (+)Tregs was increased from (8.41 ±1.68)% to (21.34 ±4.20)% (t=2.72, P=0.013). At baseline, CD(8) (+)T cells, CD(8) (+)CD(25) (+)T cells and CD(4) (+)Tregs were detectable in the peripheral blood, but no significant changes were observed after treatment. Linear correlation analysis revealed that the difference before and after treatment in CD(4) (+)T cells and CD(4) (+)CD(25) (+)T cells was negatively correlated with the ratio of change in CD(8) (+)Tregs before and after treatment (r=-0.61, P=0.013; r=-0.72, P=0.001 respectively). In the peripheral blood of patients with stable COPD, there was the expression of CD(8) (+)Tregs and CD(4) (+)Tregs. Muscarinic receptor antagonist, tiotropium bromide, can promote the amplification of CD(4) (+)T cells, inhibit the expression of CD(25) (+)T cells, and enhance the expression of CD(8) (+)Tregs. CD(8) (+)Tregs and CD(4) (+)Tregs can be used as new indicators to understand the immune status of patients. They are helpful in judging the treatment efficacy and disease immunophenotype.

DNA barcoding is a rapidly developing frontier technology in the world and will be useful in promoting the quality control and standardization of traditional Chinese medicine. Until now, many studies concerning DNA barcoding have focused on leaf samples but rarely on Chinese herbal medicine. There are three issues involved in DNA barcoding for traditional Chinese medicinal materials: (1) the extraction methods for total DNA of the rhizomes of the medicinal materials; (2) intra-specific variation among samples from different places of origin; (3) accuracy and stability of this method. In this study, Gentianae Macrophyllae Radix was used to verify the stability and accuracy of DNA barcoding technology. Five regions (ITS2, psbA-trnH, matK, rbcL, and ITS) were tested for their ability to identify 86 samples of Gentianae Macrophyllae Radix and their adulterants. After improving the DNA extraction method, genomic DNA from all samples was successfully obtained. To evaluate each barcode's utility for species authentication, PCR amplification efficiency, genetic divergence, and species authentication were assessed. Among all tested regions only ITS2 locus showed 100% of PCR amplification and identification efficiencies. Based on the established method, we successfully identified two samples of Gentianae Macrophyllae Radix bought in pharmacy to the original species.

Objective： This study was designed to observe the efficacy and side effects of autologous hematopoietic stem cell transplantation (AHSCT) in the treatment of hematological malignancies and solid tumors. Methods： In the 7 patients, two received autologous bone marrow transplantation (ABMT) and five received autologous peripheral blood stem cell transplantation (APBSCT). The conditioning regimen consisted of VCCA (Vincristine, Me-CCNU, Ara-C, CTX) and TLI(total lymph irradiation) for malignant lymphoma, VCCED (VCR, Me-CCNU, CTX, Vp-16, DNR) and TBI for acute myeloid leukemia-M4, VCCME (VCR, Me-CCNU, CTX, Mitoxantron,Vp-16) for breast cancer. All harvests of stem cells were stored at 4℃ except one at -80℃ ,than transfused back to the patients within 72 hours without purgation. Results： The number of mononuclear cells and CD34＋ cells in harvest in APBSCT patients was (7.45± 5.89)× 108/kg and (18.62± 4.74)× 106/kg,respectively. The patients' granulocyte count reached ≥ 0.5× 109/L on day＋ 9.6 and＋ 11, platelet count reached ≥ 50× 109/L on day ＋ 12.6 and＋ 21.5 and reticulocyte reached ≥ 0.5％ on day＋ 11.2 and＋ 16.5,respectively,after APBSCT and ABMT. The side effects were mainly the gastrointestinal reactions. Up to now, no relapse were seen but four women had developed secondary amenorrhea after AHSCT. Conclusion： AHSCT is an efficient way for malignant tumors and there were earlier hematopoietic reconstitution and fewer side effects in patient with APBSCT than with ABMT. The impairment of gonad by conditioning may affect the quality of life.

OBJECTIVETo study a method for extraction and analysis of volatile components from Chrysanthemum morifolium 'gonghuangjv' cv. nov (CM GHJ) and C. morifolium 'gongbaijv' cv. nov (CM GBJ) by solid-phase microextraction (SPME) and gas chromatography-mass spectrometry (GC-MS).

METHODThe volatile components were extracted in different temperature, different balance period and different extraction fiber using head space solid-phase microextraction (HS-SPME), and were identified by CGC-MS. The variety in integral area of each component was observed in different conditions and its relative content was determined by normalization of area.

OBJECTIVETo explore the associations between behavioral risk factors and overweight and obesity among Chinese primary and middle school students in 2010.

METHODSA total of 149 912 primary and middle school students aged 9 - 18 were selected from "2010 National Physical Fitness and Health Surveillance" while underweight students excluded. Questionnaires and height, weight and other physical index were performed. Logistic regression was used to analyze the association between overweight, obesity and sleep time, diet, physical exercise intention and behavior as well as sedentary behavior.

RESULTSOf students surveyed, the proportion of short sleep time was higher in obese students than in normal weight students, the prevalence of short sleep time was 93.60% (118 394/126 491), 94.39% (15 053/15 947) and 95.09% (6782/7132) in normal weight, overweight and obese students, respectively (P < 0.05); the proportion of egg intake with no more than 3 times per week was lower in obese students than in normal weight students (56.49% (4025/7125) vs 65.25% (82 518/126 464)) (P < 0.05); the proportion of never drinking milk was lower in obese students than in normal weight students (7.08% (505/7134) vs 7.55% (9 545/126 503)) (P < 0.05); and when compared with those of normal (29.53%, 37 354/126 482), more overweight students reported that they had spent 2 or more hours on homework (30.17%, 4 809/15 941) (P < 0.05). The proportions of physical activity intentions were significantly lower in obesity group of male students than those of normal male group, and the proportion of liking physical education, being willing to participate in the extracurricular sports activities, and being willing to participate long running exercise was 67.7% (4828/7134), 71.2% (5083/7135) and 35.9% (2560/7135) in obese students compared with 68.6% (86 776/126 511), 72.6% (91 814/126 509) and 47.4% (59 914/126 512) in normal weigh students, respectively. In the 13 - 15 age group, the proportion of having been physically active for a total of at least 60 minutes per day was lower in obese group (19.87%, 376/1893) than in normal group (20.66%, 8 253/39 941) (P < 0.01). Logistic regression analysis showed that the students with short sleep time were more likely to get obesity than those without short sleep time (adjusted odds ratio (AOR): 1.11, 95%CI: 1.00 - 1.25). Egg intake with no more than 3 times per week was negatively associated with the probabilities of being at risk for obesity (AOR: 0.88, 95%CI: 0.83 - 0.92), while, never drinking milk was independently related to obesity (AOR: 1.14, 95%CI: 1.03 - 1.25). Disliking physical education (AOR: 1.23, 95%CI: 1.16 - 1.30), unwilling to participate long running exercise (AOR: 2.16, 95%CI: 2.05 - 2.28) and spending 2 or more hours on homework (AOR: 1.09, 95%CI: 1.02 - 1.15) were independently related to obesity. The patterns of influence factors in different groups were not alike.

CONCLUSIONOverweight and obesity prevalence was higher in China's primary and middle school students in 2010, and the bad dietary behavior, static life style were highly interconnected.
