Effects of “Sweat Soaking Method ”on the Content of Genkwanin in Wikstroemia indica and Its Anti-oxidation Ability / 中国药房

OBJECTIVE：To compare the content changes of active/toxic ingredient genkwanin in ethanol extract from Wikstroemia indica before and after processing with “sweat soaking method ”and the effects of processing method on its anti-oxidation ability. METHODS ：HPLC method was adopted to determine the content of genkwanin in W. indica before and after processing with “sweat soaking method ”. The separation was performed on Diamonsil C 18 column with 0.2％ phosphoric acid solution-methanol as mobile phase （gradient elution ）at the flow rate of 1 mL/min. The column temperature was 30 ℃ and detection wavelength was set at 346 nm. The sample size was 20 µL. SD rats were randomly divided into blank group ，W. indica raw product ethanol extract group （317.52 mg/kg，called“raw-product group ”as short ）and W. indica processed product ethanol extract group （317.52 mg/kg，called“processed-product group ”as short ），with 6 rats in each group. Blank group was given constant volume of 1.0％CMC-Na solution intragastrically ，and administration groups were given relevant medicine suspension intragastrically；all of them were given 20 mL/kg，once a day ，for consecutive 14 days. The contents of serum oxidant stress indexes（MDA，CAT，SOD）in rats were determined by ELISA. RESULTS ：The linear range of genkwanin were 0.147-27.360 μg （r＝0.999 9）；RSDs of precision ，reproducibility and stability tests were all lower than 3％ ；average recoveries were 98.64％-98.92％（RSD＜1％，n＝3）. Before and after processing with “sweat soaking method ”，average contents of genkwanin in W. indica were 0.377 6 and 0.234 0 mg/g. Compared with blank group ，the serum content of SOD in raw-product group was increased significantly ，while CAT content was decreased significantly （P＜0.05 or P＜0.01）；the serum content of MDA was decreased significantly in processed-product group ，while SOD content was increased significantly （P＜0.05 or P＜0.01）. MDA content of processed-product group was significantly lower than that of raw-product group ，while SOD content was significantly higher than raw-product group （P＜0.05）. CONCLUSIONS ：After proce ssing with “sweat soaking method ”，the content of genkwanin in W. indica is decreased ，and antioxidant activity is increased .“Sweat soaking method ”processes certain function of “reducing toxicity and increasing efficiency ”.

Half-gloving cordectomy: a modified procedure for concealed penis / 中华男科学杂志

<p><b>OBJECTIVE</b>To search for a simple surgical procedure for the treatment of concealed penis that may have better effect and less complications.</p><p><b>METHODS</b>We used a modified surgical method in the treatment of 58 patients with concealed penis aged from 3 to 15 (mean 6.8) years. The operation was simplified and involved the following steps: wholly unveiling the penis glans, half-degloving the foreskins, cutting off all the adhesive fibers up to the penile suspensory ligaments, and liberating the external penis.</p><p><b>RESULTS</b>The operation was successful in all the patients, with the operative time of 15 -45 (mean 33) minutes, hospital stay of 2 - 5 (mean 3.5) days, but no complications except mild foreskin edema in 5 cases. The external penis was prolonged from 0.5 - 2.8 (mean 1.4) cm preoperatively to 3.2 - 8.5 (mean 3.9) cm postoperatively. The patients were followed up for 1 -3 years, all satisfied with the length and appearance of the penis, and their sexual and reproductive functions were normal.</p><p><b>CONCLUSION</b>The modified surgical procedure for concealed penis is simple and effective, with desirable outcomes, few postoperative complications and no damage to sexual and reproductive functions.</p>

Ileum to the S-type of suture produced orthotopic neobladder-with a three cases report / 肿瘤研究与临床

objective To evaluate the clinical application value of ileum to the S-type of suture pro- duced orthotopic neobladder.Methods Radical cystectomy and ileal neobladder with"S"shape were per- formed in 3patients with transitional cell carcinoma.Ureter implant into neobladder with embedding nipple techniques,bottom of neobladder coincide with urethra stump.Results The average operative time to form a neobladder was 5 hours,average bleeding volume was 366 ml during operation,3 cases can control urine dur- ing daytime,nycturia 1-3 times every night.Neobladder has a large capacity,low pressure,and electrolytes of blood was normal.Conclusion The construction of an ileal neobladder using a smaller part of ileum that has been completely detubularized and fashioned by S shape is easy and agreeable to perform.This mode of oper- ation has low complication rates,achieves adequate capacity at low pressure,and provides satisfactory conti- nence rates.It is a fine scheme to treat invasion and multiple carcinoma of bladder.
