Acta Pharmaceutica Sinica 2005;40(6):539-543
Aim To develop an HPLC method for the determination of Aconitum alkaloids extracted from Radix aconiti preparata in rats. Methods Waters 2690@996 PAD system was used. The analytical column was a Halsil 100 C18 column (250 mm×4.6 mm ID, 5 μm). The mobile phase was water, methanol and diethyl amine at the ratio of 75∶ 25∶ 0.1. The flow rate was 0.9 mL·min -1. The wavelength of the detector was 240 nm. Results The linear ranges of aconitine in the heart, spleen, lung and kidney were 0.4-100 μg·mL -1, the correlation coefficients were 0.997 2, 0.998 6, 0.999 3 and 0.999 4, respectively. The linear range of aconitine in liver was 2-200 μg·mL -1 and the correlation coefficient was 0.999 0. The linear ranges of hypaconitine in heart, liver, spleen, lung, kidney, brain and spinal cord were 5-100 μg·mL -1, the correlation coefficients were 0.999 4, 0.999 7, 0.999 8, 0.998 4, 0.999 8, 0.999 8 and 0.999 7, respectively. Detection limits (S/N=3) of aconitine and hypaconitine were 0.4 μg·mL -1. The recoveries of aconitine and hypaconitine ranged from 88.7% to 102.2% and 86.5% to 101.3%, respectively, and the RSD of precision of aconitine and hypaconitine was 10%. Conclusion It appears to be an accurate and effective method that can offer reference basis for in toxication of Radix aconiti preparata clinically.

Objective To investigate the laws of the treatment of diabetic retinopathy with traditional Chinese medicine.Methods By searching domestic literature of treating DR with traditional Chinese medicine in CNKI from 2000 to 2010, made primary summary and analyzed. Results 85 eligible published documents were found involving 147 medicinal herbs. Herbs with the functions of tonifying, activating blood circulation and eliminating stasis and heat were mostly seen.Cases reported in literature were mainly non-proliferative lesions,occupying a ratio of 58.82%;drug observation time was mainly 12 weeks, occupying a ratio of 44.17%. Conclusion Asthenia,statis and heat were pathological factors existing throughout the whole process of DR. Invigorating, romoting blood circulation, and,cooling blood should be the basic therapeutic methods.

ObjectiveTo evaluate nonoperative management of adult blunt hepatic injury. MethodThe outcome of 132 cases with adult blunt hepatic trauma admitted in this hospital between Oct 1982 and Oct 2002 was analyzed. Thirty-four cases (25.8%) were treated by nonoperative management. Before 1995, only a portion of patients underwent CT scan and after 1995, diagnosis of liver injury was established by CT scan in all cases. ResultThe nonoperative management rate before 1995 was 16.7% (14/84) and after 1995, it was 41.7% (20/48)(P0.05). ConclusionWith the progress of image monitoring and life support system, some patients of blunt hepatic injury could be managed by conservation therapy.

OBJECTIVE:To establish a method for the main active components in Citrus chacheiensis with different storage time (1-19 years). METHODS:HPLC was conducted to determine the content of hesperidin:the column was Diamonsil C18 with mobile phase of methanol-acetic acid-water(35∶4∶61,V/V/V)at a flow rate of 1.0 ml/min,detection wavelength was 283 nm,col-umn temperature was 25 ℃,and the injection volume was 5 μl;the contents of nobiletin and tangeretin:the column was Diamon-sil C18 with mobile phase of water-methanol(gradient elution)at a flow rate of 1.0 ml/min,detection wavelength was 326 nm,col-umn temperature was 25 ℃,and the injection volume was 10 μl;and the content of synephrine:the column was Diamonsil C18 with mobile phase of methanol-potassium dihydrogen phosphate solution(taking 0.6 g potassium dihydrogen phosphate,1.0 g sodi-um dodecyl sulfate,1 ml glacial acetic acid dissolved to 1 000 ml)(65∶35,V/V)at a flow rate of 1.0 ml/min,detection wavelength was 275 nm,column temperature was 25 ℃,and the injection volume 20 μl. RESULTS:The linear range was 500-4 500 ng for hesperidin(r=0.999 8),38.816-388.16 ng for nobiletin(r=0.999 6),19.936-199.36 ng for tangeretin(r=0.999 5)and 640-2 560 ng for synephrine(r=0.999 9);RSDs of precision,stability and reproducibility tests were lower than 3%;recoveries were 96.42%-102.75%(RSD=2.54%,n=6),97.42%-99.95%(RSD=2.46%,n=6),99.26%-106.19%(RSD=2.31%,n=6) and 97.47%-99.76%(RSD=1.95%,n=6),respectively. CONCLUSIONS:The method is simple and stable with good reproducibility, and can be used for the contents determination of main active components in C. chacheiensis with different storage time. Pericarpi-um citri“the older the better”may be irrelevant to the change of the contents of the above-mentioned 4 active components,and it is speculated related to the release of volatile oil content to ease dryness.

OBJECTIVETo investigate the application of intense pulsed light (IPL) depilation in the auricular reconstruction with totally expanded skin and its suitable parameter.
METHODSFrom February 2009 to September 2013, one tissue expander(100 or 150 milliliters) were implanted under the skin of mastoid in 126 patients who suffered from microtia. During the skin expanding, the hair on the expanded skin was depilated by JPL technique. The parameter, operation, interval, the depilation result and the complication were recorded. The autologous rib cartilage frameworks were implanted in the second phase of auricular reconstruction.
RESULTSThe energy of IPL was 20 - 35 J/cm2 (mean 25. 3 J/cm2), the width of pulse was 26 - 30 ms ( mean 27. 9 ms), the interval between two operations was 4 weeks. Ninety-six patients were cured(76. 2%, 96/126). The total depilation efficient is 96. 8% (122/126). A fine banding blisters was found in one patient whose depilation areas was marked by black pen. Skin erythema was found in five patients and skin pigmentation was found in 7 patients. There were no skin necrosis and expander exposure in all patients. During 6 - 12 months of follow-up period, ninety-two patients were cured (73.0%, 92/126) and the total depilation efficient is 92. 9% (117/126).
CONCLUSIONSIPL depilation during the skin expanding is feasible and safe with careful procedure. The hairless expanded skin is enough to cover the framework, as well as the post-auricular area. The appearance of reconstructed ear is better without hair.
