China Journal of Chinese Materia Medica 2014;39(15):2964-2967
The paper aims to study the pharmacokinetic parameters of gastrodin in rats effected by compound compatibilitiy and different doses of Tiangou Jiangya capsule. The extracts from Gastrodiae Rhizoma( equivalent to gastrodin 16.82 mg x kg(-1) and Tiangou jiangya capsule (equivalent to gastrodin 8.410, 16.82, 33.64 mg x kg(-1)) were oral administrated to rats respectively. The plasma were taken at various time points and treated with acetonitrile to measure the contents of gastrodin by HPLC method. The mean plasma concentration-time data were analyzed by 3P97 pharmacokinetic software and the pharmacokinetic parameters between groups were treated by SPSS 16.0. The results showed that gastrodin in rat was fitted to one-compartment model, Cmax and AUC of Tiangou Jiangya capsule were in direct proportion to oral administration, and t1/2Ka had nothing to do with doses, which indicated that gastrodin was fitted first-order rate transfter process in vivo. Morever, comparison with the Gastrodiae Rhizoma extract, isodose gastrodin in Tiangou Jiangya capsule showed a significant decrease for Cmax, Ke and increase for t1/2Ke, V/Fc, this indicated that compound compatibility can delay the absorbtion of gastrodin, prolong the resident time and promote the distribution in vivo, but its bioavailability is not significantly effected.

Medical Journal of Chinese People's Liberation Army 2001;0(08):-
To investigate the influential factors of different concentrations of some reagents and the comparability among the laboratories of RAPD. RAPD was carried out with different concentrations of reagents and three different amplified cyclers to amplify 11 strains of pathogenic vibrios. 11 strains of pathogenic vibvios were genotyped into 4 types, and could be easily repeated.The different concentrations of primer and 4 dNTP could influence the result of RAPD,but the fingerprints of RAPD produced respectively with 3 amplified cyclers were consistent. It is suggested that RAPD can be compared among the laboratories with the standard reagents.

OBJECTIVETo explore the optimized rehabilitation program in the treatment of post-stroke hemiplegia at the recovery stage.
METHODSBased on the randomized controlled principle, 60 patients were randomized into an rehabilita tion + massage group (group A) and an rehabilitation + acupuncture group (group B), 30 cases in each one. Bobath sport therapy and functional training were adopted in the two groups. In the group A, the massage therapy was added. The rolling method and palm-rubbing method were used on the affected side, the pressing, kneading and plucking methods were applied to Jianliao (LI 15), Jianzhen (SI 9), Quchi (LI 11), Huantiao (GB 30), Weizhong (BL 40), Chengshan (BL 57), Zusanli (ST 36) and the other acu points; and the nipping method was adopted at the twelve Jing-well points. In the group B, acupuncture was applied to Baihui (BL 20), Jianliao (LI 15), Quchi (LI 11), Shousanli (LI 10), Huantiao (GB 30), Yanglingquan (GB 34), Jiexi (ST 41) and the other acupoints. The treatment was given once a day, 5 treatments a week in the two groups. The efficacy was evaluated in 3 weeks. Fugl-Meyer scale, Barthel index (BI) score, modified Rankin scale and stroke-specific quality of life (SS-QOL) were used to assess the limb motor function, the activity of daily life (ADL), independent activity of life and the quality of life of the patients in the two groups before and after treatment. Based on the total cost and benefit, the health economics evaluation was conducted in the patients of the two groups.
RESULTSThe treatments all improved the limb motor function (group A: 26.00 (22) vs 37.00 (33); group B: 30.50 (21) vs 39.50 (36)), the independent activity of life, ADL (group A: 43.50 +/- 22.25 vs 57.50 +/- 22.25; group B: 52.83 +/- 16.59 vs 66.67 +/- 12.82) and the quality of life (group A: 122.23 +/- 30.00 vs 145.50 +/- 28.14; group B: 132.43 +/- 23.87 vs 151.47 +/- 22.37) in the patients of the two groups. The differences in all the indices were significant statistically before and after treatment in the two groups (all P<0.05). Above indices after treatment were not different obviously between the two groups (all P>0.05). In terms of health economics, the expense was decreased by RMB 688.48 while BI was increased by every 5 score in group A in comparison with the group B.
CONCLUSIONBoth the rehabilitation and massage therapy and the rehabilitation and acupuncture therapy improve the limb motor function and the quality of life in the patients of post-stroke hemiplegia. The therapeutic efficacies are similar between the two therapeutic programs. The program of rehabilitation and massage is more economical in the aspects of ADL improvement, being advantageous at simple operation and low cost.

Objective To investigate the effects of spine region of interest (ROI),tracking range,and real-time image contrast ratio on the positioning errors of cyberknife.Methods The LTT dynamic phantom was used to develop a spine tracking plan and perform treatment,and the target positioning system was used to preset the phantom and obtain real-time preset image and positioning error.Based on the realtime preset image,spine ROI,tracking range,and real-time image contrast ratio were changed to observe the changes in positioning error and related parameters.Pearson correlation analysis was performed.Results The change in tracking range did not change the positioning error in spine tracking,and tracking range was not correlated with positioning error (R =0,P =1).The changes in ROI and image contrast ratio did not affect the translation error,but affected the rotation error,especially the rotation error in left-right direction (r =0.533 and 0.693,P=0.002 and 0.026).The image contrast ratio had the most obvious effect,with an amplitude of variation up to 2.2°.Conclusions The change in tracking range does not affect the positioning errors in spinal tracking,but the changes in ROI and image contrast ratio can cause varying degrees of changes in positioning errors,which should be taken seriously in cyberknife treatment.
