OBJECTIVETo evaluate the short-term and long-term effects on treatment of neck pain caused by cervical spondylosis with the combination of acupuncture and moxibustion with seed-size moxa cone.

METHODSOne hundred and forty-five patients of neck pain were randomly divided into an acupuncture-moxibustion group (49 cases), an acupuncture group (48 cases) and a moxibustion group (48 cases). Acupoints of Bailao (Extra), Dazhui (GV 14), Jianzhongshu (SI15) and Zhongzhu (TE 3) were adopted for all the 3 groups. Acupuncture was applied at all the acupoints with 20 min needling retention for the acupuncture group. Moxibustion with seed-size moxa cone was used with 5 cones on each point for the moxibustion group. And both acupuncture and moxibustion with seed-size moxa cone were adopted for the acupuncture-moxibustion group. The treatment was applied once every 3 days, and 10 treatments should be finished within 4 weeks. Follow-up should be carried out for 3 months. The short-term and long-term effects were evaluated with the scores of Northwick Park Pain Questionnaire (NPQ) and McGill Pain Questionnaire (MPQ) as the indices of therapeutic effect.

RESULTSThe NPQ score and MPQ score of all the 3 groups after the treating course and the 3-month follow-up were both decreased when compared with those before the treatment (all P<0. 05). The scores of NPQ and MPQ the acupuncture-moxibustion group were lower than that of the other two groups. And the difference had obvious significance (P<0. 05). High efficiency of pain relieving for cervical spondylosis could be found in all the 3 groups, which showed that short-term and long-term effects were good for all the 3 groups. And the highest curative effect could be found in acupuncture-moxibustion group.

CONCLUSIONCombination of acupuncture and moxibustion with seed-size moxa cone has reached a superior effect in short-term and long-term for neck pain caused by cervical spondylosis.

The herbs used as the material for traditional Chinese medicine are mostly planted at mountain areas where there is appropriate weather condition. Due to the complex terrain condition in mountain area, the planting at such places is always associated with a scattered pattern, which inevitably bring difficulty to the work of accurate measurement for the planting area. Advanced research about monitoring the planting area for medicine-herb under complex environmental condition is so critical and meaningful for developing the medicine-herb planting to a large scale and an industry. Therefore, this research, taking the planting of Herpetospermum pedunculosum in Luding county as an example, utilizes RS&GIS: using the image data from TM and ETM datum as the remote sensing information source, integrating GPS data from quadrat survey on the spots, and analyzing on a GIS platform, to extract the planting area of H. pedunculosum in Luding county. The results indicate that: (1) the method and technology used to estimate the planting area of H. pedunculosum are feasible and can be applied to monitoring the planting area of medicine-herb at mountain area under complex environmental conditions: (2) the planting area of H. pedunculosum in Luding county is estimated to be 857. 246 acres by the methods utilized in this research, which is closed to the value from local statistical data with an error range less than 5%; (3) in consideration of those inevitable errorrs generating from the procedures such as remote sensing data acquisition, data preprocessing, data interpretation, and so on, and the fact that the classification of remote sensing data, which must be implemented by those above procedures, was used directly to extract the herb type, the accuracy of area estimation for the herb is significantly influenced by the accuracy of classification for herb type, and the estimated area is inevitably associated with some error.

Background Researches showed that multifocal electroretinogram (mfERG) is able to assess the retinal function in the eyes with acute Vogt-Koyanagi-Harada ( VKH ) syndrome. But the mfERG characteristics of convalescence stage of VKH are still below clear. Objective Present study was to compare and follow up the variation process of visual acuity and mfERG in acute and recovery stages of VKH syndrome. Methods This was a clinic-based retrospective study. Visual acuity, mfERG and fundus fluorescence angiography ( FFA ) were recorded from 35 eyes of 18 acute VKH cases. The period of follow-up in recovery stage lasted about 18 months with the repetitive recording results for 4 times. Results In this study, the visual acuity range in acute stage VKH was 0. 01 to 1.0, and 91.4% (32/35 eyes) was below 0.6. Compared with normal control group, the visual acuity was significantly decreased (P＜0.01). The response densities (amplitudes) of N1 ,P1 waves of the first-order kernel were significantly lowed in all the 6 rings,and the implicit times of 1-4 rings of both waves were significantly prolonged in acute VKH eyes(P＜0. 05). The abnormalities of retinal function showed a regional difference at the posterior pole retina with the dominant change in the first ring,showing a cutting off78% in the P1 amplitude. The abnormal degree of mfERG was more serious as the the increase of retinal eccentricity. In 2 months of convalescence after glucocorticosteroids therapy,the range of visual acuity were 0. 1-1.2 ,and the amplitudes of N1, P1 of 1-2 rings were greatly elevated in comparison with acute on-set (P＜0. 05 ). However, there was still a remarkable difference in the amplitudes of from 1 through 6 rings,comparing with normal. The response density of P1 wave from whole recording region was only 44% of normal. Though the visual acuity was stable during the follow-up duration, a decreasing tendency in N1 and P1 amplitudes were seen. The implicit times of both wave shortened only in 1-3 rings in recovery stages of VKH (P＜0.05). Conclusion VKH syndrome cause serious damage of posterior retinal function.Macular region is the site with greater retinal functional lesion and restore before and after medication. This hardly recovery of retinal function can last over one and half year,even satisfied visual acuity is stable after proper treatment.

On account of the dense cuticles of the fresh stem and the light, hard and pliable texture of the dried stem, Dendrobii Caulis is difficult to dry or pulverize. So, it is very important to the ancient doctors that Dendrobii Caulis should be properly treated and applied to keep or evoke its medicinal effects. The current textual research results about the preliminary processing, processing and usage methods of Dendrobii Caulis showed that: (1) In history the clinical use of fresh or processed Dendrobii Caulis as teas and tinctures were very common. (2) Its roots and rhizomes would be removed before using. (3) Some ancillary approaches were applied to shorten drying times, such as rinsing with boiling mulberry-ash soup, washing or soaking with liquor, mixing with rice pulp and then basking, etc. (4) According to the ancients knowledge, the sufficient pulverization, by means of slicing, rasping, hitting or pestling techniques, was necessary for Dendrobii Caulis to take its effects. (5) The heat processing methods for Dendrobii Caulis included stir-baking, stir-frying, steaming, decocting and stewing techniques, usually with liquor as an auxiliary material. Among above mentioned, steaming by pretreating with liquor was most commonly used, and this scheme was colorfully drawn in Bu Yi Lei Gong Pao Zhi Bian Lan (Ming Dynasty, 1591 CE) ; moreover, decocting in advance or long-time simmering so as to prepare paste products were recommended in the Qing Dynasty. (6) Some different processing programs involving stir-baking with grit, air-tightly baking with ondol (Kangs), fumigating with sulfur, which appeared in modern times and brought attractive outward appearance of the drug, went against ancients original intentions of ensuring drug efficacy.

BACKGROUNDThe delivery of glucose from the blood to the brain involves its passage across the endothelial cells of the blood-brain barrier (BBB), which is mediated by the facilitative glucose transporter protein 1 (GLUT(1)), and then across the neural cell membranes, which is mediated by GLUT(3). This study aimed to evaluate the dynamic influence of hyperglycemia on the expression of these GLUTs by measuring their expression in the brain at different blood glucose levels in a rat model of diabetes. This might help to determine the proper blood glucose threshold level in the treatment of diabetic apoplexy.

METHODSDiabetes mellitus was induced with streptozotocin (STZ) in 30 rats. The rats were randomly divided into 3 groups: diabetic group without blood glucose control (group DM1), diabetic rats treated with low dose insulin (group DM2), and diabetic rats treated with high dose insulin (group DM3). The mRNA and protein levels of GLUT(1) and GLUT(3) were assayed by reverse transcriptase-polymerase chain reaction (RT-PCR) and immunohistochemistry, respectively.

RESULTSCompared with normal control rats, the GLUT(1) mRNA was reduced by 46.08%, 29.80%, 19.22% (P < 0.01) in DM1, DM2, and DM3 group, respectively; and the GLUT(3) mRNA was reduced by 75.00%, 46.75%, and 17.89% (P < 0.01) in DM1, DM2, and DM3 group, respectively. The abundance of GLUT(1) and GLUT(3) proteins had negative correlation with the blood glucose level (P < 0.01). The density of microvessels in the brain of diabetic rats did not change significantly compared with normal rats.

CONCLUSIONSChronic hyperglycemia downregulates GLUT(1) and GLUT(3) expression at both mRNA and protein levels in the rat brain, which is not due to the decrease of the density of microvessels. The downregulation of GLUT(1) and GLUT(3) expression might be the adaptive reaction of the body to prevent excessive glucose entering the cell that may lead to cell damage.

OBJECTIVETo investigate the mechanism underlying the curcumin-induced apoptosis of nasopharyngeal carcinoma (NPC) cell line NCE cells.

METHODSThe characteristics of apoptosis were identified by observation acridine orange and ethidium bromide stains, ultrastructure assay, DNA fragmentation assay and TdT-mediated dUTP nick end labeling method (TUNEL). Mitochondrial membrane potential (delta psi m), activity of caspase-3, cytosol cytochrome C and expression of gene Fas were determined by flow cytometry (FCM), Western Blot and reverse transcription-polymerase chain reaction (RT-PCR).

RESULTSSeveral evidences of apoptosis were obtained from curcumin-treated NCE cells by acridine orange and ethidium bromide stains, ultrastructure identification, DNA fragmentation assay and TUNEL staining. And the mean TUNEL-positive rates increased significantly at the 3 different time points (12 h, 24 h and 48 h; 25.6%, 40.3% and 54.5%, respectively). In the curcumin-treated-groups, delta psi m altered significantly and the positive rates increased in a time-dependent manner. At the 3 different time points, the mean positive rates were 26.8%, 42.3% and 68.2%, respectively. When caspase-3 activity was detected, 80.5% cells presented proteases activities after 12 h incubation with curcumin. Western Blot analysis showed that cytoplasmic cytochrome C increased significantly after incubation with curcumin. Flow cytometry and RT-PCR analysis showed that curcumin could up-regulate the Fas expression in time-depended manner , the positive rates of Fas protein increased from 33.6% to 89.9%.

CONCLUSIONSCurcumin induced apoptosis of NCE cells both through mitochondria-dependent pathway and death receptor pathway.

OBJECTIVETo explore the molecular basis of an individual featuring an ABx variant of ABO blood group system.

METHODSSerological assays were used to characterize the erythrocyte phenotypes and salivary ABH secretors. All of the seven exons and flanking introns of ABO glycosyltransferase gene were amplified with polymerase chain reaction (PCR). And the products were sequenced bidirectionally following enzyme digestion. Exons 6 and 7 were also subcloned and analyzed for haplotypes of the ABO gene.

RESULTSErythrocytes of the proband have expressed a strong A antigen and a weak B antigen, which was identified as a rare ABx variant in addition with other serological features. Nine heterozygous sites in exon 6 (297A/G) and exon 7 (467C/T, 526C/G, 657C/T, 703G/A, 796C/A, 803G/C, 808T/A, 930G/A) of the coding region of the ABO gene were identified. Based on haplotype analysis, one allele was determined as common A102, whilst another was consistent with B101 except for an 808T>A mutation which has resulted in replacement of phenylalanine with isoleucine at position 270 of glycosyltransferase B.

CONCLUSIONThe 808T>A mutation of the glycosyltransferase B gene may decrease the enzymatic activity and result in the Bx variant.
