OBJECTIVETo compare the clinical efficacy on cervical spondylotic radiculopathy between the combined therapy of massage and magnetic-sticking at the auricular points and the simple massage therapy, and conduct the health economics evaluation.

METHODSSeventy-two patients of cervical spondylotic radiculopathy were randomized into a combined therapy group, and a simple massage group, 36 cases in each one. Finally, 35 cases and 34 cases were met the inclusive criteria in the corresponding groups separately. In the combined therapy group, the massage therapy and the magnetic sticking therapy at auricular points were combined in the treatment. Massage therapy was mainly applied to Fengchi (GB 20), Jianjing (GB 21), Jianwaishu (SI 14), Jianyu (LI 15) and Quchi (LI 11). The main auricular points for magnetic sticking pressure were Jingzhui (AH13), Gan (On12) Shen (CO10), Shenmen (TF4), Pizhixia (AT4). In the simple massage group, the simple massage therapy was given, the massage parts and methods were the same as those in the combined therapy group. The treatment was given once every two days, three times a week, for 4 weeks totally. The cervical spondylosis effect scale and the simplified McGill pain questionnaire were adopted to observe the improvements in the clinical symptoms, clinical examination, daily life movement, superficial muscular pain in the neck and the health economics cost in the patients of the two groups. The effect was evaluated in the two groups.

RESULTSThe effective rate and the clinical curative rate in the combined therapy group were better than those in the control group [100. 0% (35/35) vs 85. 3% (29/34), 42. 9% (15/35) vs 17. 6% (6/34), both P<0. 05]. The scores of the spontaneous symptoms, clinical examnation, daily life movement and superficialmuscular pain in the neck were improved apparently after treatment as compared with those before treatment in the patients of the two groups (all P<0. 001). In terms of the improvements in the spontaneous symptoms, clinical examination total scores and superficial muscular pain in the' neck were more significant in the combined therapy group as compared with those in the simple massage group (P<0. 05, P<0. 01, P<0. 001). The cost at the unit effect in the combined therapy group was lower than that in the simple massage group (P<0. 05).

CONCLUSIONCompared with the simple massage therapy, the massage therapy combined with magnetic sticking therapy at auricular points achieves the better effect and lower cost in health economics.

An analytical method of fluorescent dye-labeled oligonucleotides was established by ion pair reversed phase high performance liquid chromatography(IP-RP-HPLC) which was improved by optimizing the effects of triethylamine-acetic acid(TEAA)(0-0.15 mol/L), pH(4.5-7.0) and gradient. Comparing the retention of 5, 10 and 15-mer unlabeled oligonucleotides with that of 5'-carboxyfluorescein(5'FAM) labeled oligonucleotides, the mechanism of fluorescent dye-labeled oligonucleotides retention was studied. In addition, TaqMan~(TM) probes as wellas other common fluorescent dye-labeled oligonucleotides were concerned. The results showed that the best resolution of different length fluorescent dye-labeled oligonucleotides was observed under the condition of 0.01 mol/L TEAA and pH 7.0. The retention behavior of fluorescent dye-labeled oligonucleotides was different from that of unlabeled oligonucleotides significantly, and therefore they can be separated completely. The results indicated that the retention of unlabeled oligonucleotides enhanced with the increase of the length of molecule. In contrast, the retention of fluorescent dye-labeled oligonucleotides was reduced with the increase of the length of molecule. For the hydrophobicity of fluorescent dyes made a great impact on the retention, a longer retention time the labeled oligonucleotides would take while the hydrophobicity of fluorescent dyes was higher. However, the effect of the hydrophobicity was limited as the length was increased to a certain level.

OBJECTIVE Dynamics of serum and urine metabolites in hepatic injury rats induced by ethanolic extract from Rhizoma Dioscoreae Bulbiferae(RDB)was investigated by 1H-NMR-based metabo?nomic methods in order to discover early biomarkers of liver toxicity induced by RDB. METHODS Rats were ig adminisetred with RDB at a dose of 5 g·kg-1 for 28 d. Rats were sacrificed 3,7,14 and 28 d af?ter RDB administration,as well as after a recovery period,respectively. Blood was taken for routine bio?chemical analysis by an automatic biochemical analyzer. Liver/body mass indexes were calculated ,and liver pathological changes were observed with hematoxylin-eosin staining. Urine samples were collected before and 3,7,14 and 28 d after RDB administration,respectively,as well as after withdrawal. Metabo?nomic analysis was carried out for serum and urine samples. Principal component analysis and orthogonal partial least squares-discriminant analysis were used for screening and identifiying early biomarkers. RESULTS Compared with the control group,total bilirubin (TB) and total cholesterol (TC) values were increased in 3-28 d in RDB group(P<0.05,P<0.01). Total bile acid(TBA)was elevated in 7-28 d (P<0.05,P<0.01). TB,TC and TBA became normal after discontinuation with RDB. There was no significant difference between RBD-treated group and control group in the activity of glutamic-pyruvic transaminase and glutamic-oxaloacetic transaminase,and the content of glucose also was not different between the two groups. The ratio of liver/body mass was elevated at 3-28 d(P<0.01)but returned to normal after withdraval of RDB. The enlargement and necrosis of hepatocytes were observed 7 d after RDB administration,and lesion degree was aggravated with the extension of RDB delivery time. Meta?bonomic analysis showed that the serum lipids (low density lipoprotein/very low density lipoprotein (LDL/VLDL),glutamic acid,choline phosphate and glycerolphosphatecholine were increased in the early stage. Pyruvate and N-acetylglutamate were decreased in urine. These metabolites became normal 7 d after discontinuation with RDB. CONCLUSION The serum lipids (LDL/VLDL),glutamic acid,glycerol phosphate choline,as well as urine pyruvic acid salt and N-acetyl glutamate may be used as the early biomarkers for liver toxicity induced by RDB.

Objective To evaluate the left ventricular twist in patients with coronary heart disease (CHD) with two-dimensional strain echocardiography (2DSE). Methods Thirty-eight patients with CHD and 31 control subjects proved with selected coronary angiography were enrolled. Two-dimensional images from LV short-axis views at the levels of mitral annulus and apex in 3 continuous cardiac cycles were recorded. LV ejection fraction (LVEF) was calculated with bi-plane Simpson's method, torsion and torsional rate were obtained in each plane, and the corresponding curve was accessed. Results No statistical difference of conventional echocardiographic parameters such as LV diameter, left atria diameter, LVEF, FS, E/A and E-wave deceleration time were detected, while significant difference of torsional direction (P＜0.01) and global torsion rate (P＜0.05) were found between the two groups. Conclusion The global torsional rate and torsional direction have higher sensitivity than conventional echocardiography in the diagnosis of CHD.

Objective: To observe the clinical effect of tuina combined with auricular point sticking on cervical radiculopathy and evaluate in health economics.
Methods: Using randomized single-blind controlled clinical design, a total of72 cases with cervical radiculopathy were randomly allocated into an observation group or a control group by the ratio of 1:1, 36 in each group. Cases in the observation group were treated with tuina combined with auricular point sticking, whereas cases in the control group were treated with tuina alone. Then the clinical effects in the two groups were observed and the cost of health economics was evaluated.
Results: The drop-out, recovery, improvement and failure cases, recovery rate and total effective rate in the observation group were 1, 15, 20, 0, 42.9% and 100% respectively, versus 2, 6, 23, 5, 17.6% and 85.3% in the control group, showing significant differences in recovery rate and total effective rate (P<0.05). As for health economics, the cost-effect in the observation group was better than that in the control group.
Conclusion: Compared with tuina alone, tuina combined with auricular point sticking can obtain better effect and lower cost in health economics for cervical radiculopathy.
