3. Effect of fertilization combinations of nitrogen, phosphorus, and potassium on yield and quality of flowers of Chrysanthemum indicum
Chinese Traditional and Herbal Drugs 2013;44(11):1495-1500
Objective: To study the effect model of various fertilization combinations of nitrogen (N), phosphorus (P), and potassium (K) and its effects on the yield of flowers of Chrysanthemum indicum (FCI) and linarin content. Methods: The "3414" mis-classification orthogonal design was used in the fertilization test of three factors (N, P, and K), quadratic regression design was adopted, and analyses on variance and the DPS were carried out by using C. indicum as material. Results: After statistical analysis, the optimized effect model of N, P, and K and the the relationship between the yield and quality of FCI were established. The optimum efficiency was the treatment with N2P2K2 in various fertilizations. No treatment or single treatment of N, P, or K could cause the reduction of yield and quality. Single-factor analysis showed that the yield and linarin content were first increased and then decreased steadily with the increase of the N, P, and K application. The two factor interaction analysis indicated that there existed an interaction range among N, P, and K with the yield as the index. Synergistic effect was observed while the amount of N, P, and K was lower than the range while antagonistic effect was observed while higher than the range. When taking the content of linarin as the index, the reaction between N-K and P-K existed a range, and the trend of linarin showed the same trend as the yield. While N-P always kept the synergistic effect. Conclusion: The optimal fertilization amounts in the optimized model of FCI are 131.280-187.254 kg/hm2 for N, 113.415-170.460 kg/hm2 for P, 118.335-220.845 kg/hm2 for K, respectively.

Objective: To observe the clinical efficacy of acupoint pressure plus long-snake moxibustion for upper-limb spastic hemiplegia after cerebral infarction. Methods: A total of 100 patients were randomized into a control group and an observation group, with 50 cases in each group. Both groups were treated with the same conventional internal medicine and rehabilitation training. The control group was treated with additional acupoint pressure therapy, and the observation group was treated with long-snake moxibustion on the basis of the treatment given to the control group. The Ashworth grade, Fugl-Meyer assessment upper limb scale (FMA-UL) and Barthel index (BI) were evaluated, and the root mean square (RMS) values of biceps brachii and flexor carpi radialis on the affected side were measured before and after treatment. The efficacy was evaluated after treatment. Results: After treatment, the total effective rate of the observation group was significantly higher than that of the control group (P<0.05). After treatment, the Ashworth grade of the observation group was superior to that of the control group (P<0.05). The scores of FMA-UL and BI in both groups increased compared with those before treatment (all P<0.05), and the scores of FMA-UL and BI in the observation group were higher than those in the control group (both P<0.05). The RMS values of biceps brachii and flexor carpi radialis in both groups decreased compared with those before treatment (all P<0.05), and the RMS values of biceps brachii and flexor carpi radialis in the observation group were lower than those in the control group (both P<0.05). Conclusion: Based on conventional internal medicine and rehabilitation training, acupoint pressure plus long-snake moxibustion has great therapeutic efficacy for upper-limb spastic hemiplegia after cerebral infarction. It can improve the degree of spasticity of the affected upper limb, reduce the muscle tone of biceps brachii and flexor carpi radialis on the affected side, and enhance the mobility of the affected limb and the activities of daily living.

OBJECTIVETo evaluate the clinical effect of arthroscopic excision of the os subfibulare in anterior-lateral ankle pain.
METHODSFrom December 2005 to Augest 2014, 16 patients suffering from pain associated with an os subfibulare in the anterior-lateral side of their ankles were reviewed. Among the patients,11 patients were male and 5 were female, with a mean age of (33.5 ± 15.6) years old. The mean maximum diameter of os subfibulare was (0.70 ± 0.26) cm. All the patients underwent excision of the osseous fragments, and had anatomic reconstruction of the anterior talofibular ligament if the anterior-lateral ankle was instable. The average follow-up period was (18.0 ± 4.5) months. To analyze the surgical outcome, American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot pain and function scales,visual analogue scale (VAS) and Tegner activity scale were assessed preoperatively and postoperatively.
RESULTSAOFAS scales were preoperative 60.15 ± 14.52 and postoperative 92.35 ± 5.73. There was a significant difference between them (t = -8.251, P = 0.000). The mean VAS score were preoperative 7.35 ± 0.46 and postoperative 2.45 ± 0.98. Statistical significance was also notable (t = 18.105, P = 0.000). Tegner score was significantly increased from preoperative 2.87 ± 1.12 to postoperative 5.78 ± 1.06 (t= -7.548, P = 0.000).
CONCLUSIONIrrespective of the size of os subfibulare, in patients with pain or instability associated with the os subfibulare, arthroscopic excision combined with reconstruction of ther anterior talofibular ligament or not was effective in restoring ankle function and eliminating pain.

To establish the online two-dimensional liquid chromatography by using double gradient liquid chromatography system and UV detector, in order to simultaneously determine the content of paeoniflorin, paenol, amygdaloside and cinnamic acid. A pump of the two-dimensional liquid chromatography was adopted as the one-dimensional separation pump. C18 (3.0 mm x 150 mm, 3 microm) was used as the analytical column, with acetonitrile as the organic phase and 0.08% phosphoric acid + 0.08% triethylamine as the aqueous phase for gradient elution at the flow rate of 0.5 mL x min(-1). Another pump of the two-dimensional liquid chromatography was adopted as the two-dimensional separation pump. PAII C18 was used as the analytical column, with acetonitrile as the organic phase and 20 mmol, pH 3.0 monopotassium phosphate as the aqueous phase for gradient elution at the flow rate of 0.8 mL x min(-1). The detection wavelengths were set at 218, 230, 275 nm by using wavelength time-switching program. The linearity range of paeoniflorin, amygdaloside, paeonol and cinnamic acid were 5.55-222 (r = 0.999 7), 6.6-264 (r = 0.999 8), 3.3-132 (r = 0.999 5) and 0.315-12.6 mg x L(-1) (r = 0.999 7), respectively. The average recoveries of the four components were between 96.12% and 103.9%. The experiment proved that this method was so rapid and accurate in determination results that it could be used for evaluating drug quality.
