China Pharmacy 2017;28(13):1834-1836
OBJECTIVE:To optimize ultrasonic extraction technology for polysaccharide from Aconiti lateralis radix praepara-ta(ALRP). METHODS:Uniform design method was applied to investigate the effects of liquid material ratio,ultrasonic time and ultrasonic temperature on extraction rate of polysaccharide from ALRP. Verification test was conducted and compared with the re-sults of conventional decoction and boiling method. RESULTS:Optimized ultrasonic extraction technology was as follow as liquid material ratio of 10 mL/g,ultrasonic time of 34 min and ultrasonic temperature of 73 ℃. The polysaccharide extraction rate in veri-fication test was 19.05%(RSD=0.60%,n=3),relative error of the predicted value (19.44%) was 2.0%,while the extraction rate was higher than decoction and boiling method(16.42%). CONCLUSIONS:Optimized ultrasonic extraction technology is sim-ple,rapid and stable with high extraction rate,which is suitable for extracting polysaccharide from ALRP.

Objective To study the effects of three therapies on shoulder pains after gynecological laparoscopies.Methods After the gynecological laparoscopies,180 patients were randomly assigned to hot compress group(n=57),oxygen therapy group (n=65)and routine care group as control group(n=58).All the patients in the three groups were given oxygen inhalation for three hours.Besides,those controls were given mental care,comfort support and massage,while those in the two experiment groups were managed with hot compress on the shoulder and oxygen inhalation via nasal tube at 2 L/min each for 2 hours at 8 am and 4 pm on the first day.The three groups were compared in terms of shoulder pains,at different time points on the first day(at 8 am,4 pm and 8 pm). Results After intervention,there were significant differences between the three groups in terms of shoulder pains(P<0?05).In both experiment groups,the scores on the shoulder pains after intervention were significantly lower than those before intervention(P<0?001). Conclusions Hot compress and oxygen treatment are both effective in relief of the shoulder pain after gynecological laparoscopy. Therefore,the therapy can be decided on economic conditions and postoperative rehabilitations.

OBJECTIVE:To optimize water extraction technology of Shenqi yiqi capsules. METHODS:The water extraction technology of Shenqi yiqi capsules was optimized by L9(34)orthogonal test with amount of water added,decoction times and decoc-tion time as factors using the extraction rate of astragaloside,calyosin-7-O-β-D-glycoside,icariin and bergenin as index,and the verification test was made. RESULTS:The best extraction technology was as follows as 8-fold water,decocting for 3 times,2 h each time;comprehensive score of 3 batches of samples in validation test were 98.95,99.71 and 99.98(RSD<2%,n=3). CON-CLUSIONS:The water extraction technology optimized by multi-index comprehensive score-orthogonal test is stable,scientific and reasonable.

Objective To evaluate the role and efficacy of preventing bone mineral loss in patients with endometriosis treated by gonadotrophin-releasing hormone analogues (GnRH-a) combined with addback therapy.Methods Prospective,randomized controlled studies of the use of GnRHa with add-back therapy in treatment of endometriosis were enrolled in this study from Medline,Embase,Cochrane library,China National Knowledge Internet (CNKI),Chinese Biological Medicine Disk (CBM) and Data Base of Wanfang.After quality assessment and data extraction,meta-analysis were conducted in the change of BMD,reproductive hormone (E2) and visual pain score (VAS) by Stata 11.0 software.Results A total of 785patients from 13 randomized controlled trail (RCT) studies enrolled in this study after exclude no following up,poor quality and repeat published studies.377 patients were in group of GnRH-a with add-back treatment and 408 patients were in group of GnRna alone.The findinds were showed in meta-analysis:(1) there was a significant difference in percentage change of bone mineral density (BMD) between two groups,the addback therapy was more effective in prevention of bone loss which was (SMD =0.223,95% CI:0.003 to 0.443,P =0.047).(2) There was no significant difference in the level of reproductive hormone between two groups (SMD =-0.053,95% CI:-0.479 to 0.373,P =0.807).(3) There was also no significant difference in the visual pain score between the two groups (SMD =-0.157,95% CI:-0.474 to 0.160,P=0.332).Conclusions GnRH-a with add-back therapy have been shown to be more effective in preventing loss of BMD than GnRH-a treatment alone.However,the long term effect of preventing BMD should be studied.
