Objective:To observe the effect of nape acupuncture on vertebral-artery type cervical spondylosis.Methods:Eighty patients with vertebral-artery type cervical spondylosis were randomly divided into nape acupuncture group and Jiaji acupuncture group,with 40 cases in each group.The patients in the nape acupuncture group were treated with the nape acupuncture plus Jiaji acupuncture,while the patients in the Jiaji group were treated with Jiaji acupuncture only,to observe the functional scale before and after treatment.Results:The total effective rate in the nape acupuncture group was 95.0%,while the total effective rate in the Jiaji acupuncture group was 82.5%.By Ridit analysis,u=5.186,P＜0.01.It indicated that the therapeutic effect in the nape acupuncture group was better than that in the Jiaji acupuncture group.Compared with Jiaji acupuncture group,the difference value of pre- and post-treatment about functional scale of vertebral-artery type cervical spondylosis and the post-treatment score have statistic differences (P＜0.01).It indicated that the therapeutic effect of nape acupuncture group was more obvious in treating vertigo than that in the Jiaji acupuncture group.Conclusion:The treatment of vertebral-artery type cervical spondylosis by Jiaji acupuncture plus the nape acupuncture may enhance the therapeutic effect significantly.

Objective To define the correlation between the proliferating cell nuclear antigen (PCNA) and metastasis-related gene nm-23-H 1, and to correlate their espressions with clinical features,radiosensitivity and prognostic variables in exophageal squamous cell carcinoma (ESCC), to establish some biological parameters obtained prior to therapy though which we can predict radiosensitivity and outcome.Methods PCNA and nm-23-H 1 expression protein were determined by immunohistochemical technique with formalin-fixed paraffin-embedded specimens from 59 patients with ESCC who had received definitive radical radiation and had been followed up for more than 3 years. The values were assessed by distributions of patients , disease factors, including age,sex,lesion site,legth ,histological grade and prognosis.Results The findings showed that the mean labelling indices of PCNA and nm-23-H 1 were significantly higher in ESCC than in the normal esophageal tissue (P0.05).Conclusions PCNA and nm-23-H 1 indices can be taken as biological endpoints to predicting therapeutic response, local and systemic control of disease.

This article was aimed to study the action of antigout effects of compoundWeifu. Through the acute gouty arthritis models of rabbits and rats induced by micro-crystal sodium urate (MSU). The histopathological changes of synovial tissues among rabbits were observed. And the contents of TNF-α, IL-1β, IL-6 in rabbit serum were determined. The swelling degree of the rats’ feet and the content of prostaglandin E2 (PGE2) from the inflammatory exudate foot induced by MSU were also determined. The antigout effects of compoundWeifu were observed. The results showed that the grade of the vascular congestion, swelling and inflammatory cell infiltration in synovial tissues in the high-dose and medium-dose CompoundWeifu group had significantly improved (P <0.05). And the levels of TNF-α, IL-1β, IL-6 in serum were significantly decreased (P< 0.05, orP < 0.01). It can obviously reduce the swelling degree induced by MSU, and the level of PGE2 in the inflammatory exudate foot (P< 0.05, orP < 0.01). It was concluded that CompoundWeifu had obvious antigout effects in the study.

Aerenchyrna formation has been described in depth in a number of species at a histological level. But large gaps remain in our understanding of its regulation as a developmental process. It is attempted to analyse essential mineral elements like K, Mg, Cu, Zn, Ca and P in the cell wall of aerenchyma cells in petioles ofS. trifolia at five different developmental stages by CSEM-EDX technique. At early stage, K and Cl concentrations in cell wall were high up to 36% and 4.3% of dry weight, respectively. It supported the hypotheses that aerenchyma spaces are filled with liquid at early developmental stages of aerenchyma in S. trifolia petiole. Mg concentration was high at stage 2, up to 0.86% of dry weight. Zinc and Cu were detected only at rapid expansion stages, during which the concentrations were up to 1.5% and 2.5%, respectively. Calcium was detected in the cell wall only at mature stages, the concentration was high up to 1.3% of dry weight at stages 4 and 5. These results confirmed that the element concentration of aerenehyma cell wall undergoes dynamic changes during different developmental stages, and a low Ca with high Zn and Cu concentration are needed for cell expansion. Copper and Zn deposition in the cell wall showed a significant positive linear correlation, suggesting that these two elements share same or similar uptake and transport mechanism in plants.

Aim To investigate the glycosidic constituents in the rhizomes of Alpinia officinarum Hance. Methods The isolation and purification of glycosides were done with column chromatography on macro porous resin, polyamides and Sephadex LH-20, whilst the structure elucidation was done by HRCI-MS and NMR (1D and 2D ) methods. Results A glycosidic ester identified as 4'-hydroxy-2'-methoxyphenol-β-D-{ 6-O-[ 4"-hydroxy-3", 5"-dimethoxy ( benzoate ) ] }-glucopyranoside ( I), along with a known compound n-butyl-β-D-fructopyranoside (II) , were isolated and characterized. Conclusion Ⅰ was found to be a new compound, named as alpinoside A, whilst Ⅱ was isolated from the genus Alpinia for the first time.

It is an important measure in improving the practical teaching quality at Chinese westem medical colleges to strengthen the training practice of part-time assistant teachers in clinical teaching bases. To establish a good training model,we should take into consideration its operability and practicability, as well as the positivity of the teachers.The key to making the training succeful is to ascertain the direction and contents, to set up an instructors' team, and to make a specific training plan.

To study the chemical constituents of the stems of Clematis parviloba, six compounds were isolated from a 95% ethanol extract by using a combination of various chromatographic techniques including column chromatography over silica gel, ODS, Sephadex LH-20, and semi-preparative HPLC. Two new phenolic glycosides, 2-((E)-3-carboxybut-2-en-yl)-4-hydroxy-3-methyl-phenyl-O-beta-D-glucopyranoside (1) and 4'-hydroxy-phenol-beta-D-[6-O-(4"-hydroxy-3", 5"-dimethoxy-benzoate)] glucopyranoside (2) were isolated, together with a known phenolic glycoside, 4'-hydroxy-3'-methoxy-phenol-beta-D-[6-O-(4"-hydroxy-3", 5"-dimethoxy-benzoate)] glucopyranoside (3) as well as three known megastigmane glycosides, linarionoside A (4), linarionoside C (5), and staphylionoside K (6). Their structures were determined on the basis of spectroscopic analysis and chemical evidence. Among them, compounds 1 and 2 were named as clemaparvilosides A (1) and B (2), respectively, and compounds 3-6 were obtained from Clematis genus for the first time.
