2. Preparation and quality control of methyl salicylate glycoside tablets
Chinese Pharmaceutical Journal 2013;48(10):797-800
OBJECTIVE: To establish the method of the preparation and test for methyl salicylate glycoside (MSG) tablets. METHODS: MSG tablets were prepared with MSG as main drug and microcrystalline cellulose and sodium carboxymethyl starch as exipients. Its detection method was studied. RESULTS: After experimental study, the high performance liquid chromatography method for related substances detection and content determination of MSG tablets were established. CONCLUSION: The prescription is reasonable and the preparation technology is reliable. The HPLC method has high accuracy and sensitivity and can be used for MSG tablets test.

Objective To determine the efficacy of hysteroscopy and laparoscopy in differential diagnosis of pregnancy-related diseases,including gestational trophoblastic neoplasia(GTN),incomplete abortion and ectopic pregnancy.Methods Twenty-seven patients with a suspected diagnosis of GTN were transferred to Peking Union Medical College Hospital from September 2003 to March 2006,and underwent hysteroscopy and laparoseopy.Clinical data of patients were reviewed retrospectively.Most patients had abnormal vaginal bleeding and persistently elevated plasma beta human chorionic gonadotropin(?-hCG) level for a median(53?37)days(range,15-125 days)after evacuation.Ultrasound revealed a lesion with affluent blood flow in intrauterine,unilateral horn of uterus,or myometrium.No positive findings were revealed by computerized tomography or X-ray of the chest in all patients.Eleven patients underwent evacuation under hysteroscope,10 patients were diagnosed and treated by laparoscopy,and 6 by hysteruscopy and laparoseopy.Results Choriocarcinoma was diagnosed in 4 patients,who achieved complete remission by chemotherapy later.The diagnosis of GTN was ruled out in the other 23 patients, including cornual pregnancy in 12,pregnancy in rudimentary horn in 1,and incomplete abortion in 10,who were cured by hysteroscopic and laparoscopic surgery and postoperative adjuvant single dose methotrexate.Conclusions The major causes of pregnancy-related abnormal bleeding include incomplete abortion,eetopic pregnancy,and GTN.Hysteroscopy and laparoseopy are effective alternative of diagnosis for differentiation of GTN from non-GTN and can also offer therapeutic treatment.

Immuno-fluorescence technique can qualitatively determine certain nuclear translocation, of which NF-κB/ p65 implicates the activation of NF-κB signal pathways. Immuno-fluorescence analysis software with independent property rights is able to quantitatively analyze dynamic location of NF-κB/p65 by computing relative fluorescence units in nuclei and cytoplasm. We verified the quantitative analysis by Western Blot. When we applied the software to analysis of nuclear translocation in lipopolysaccharide (LPS) induced (0. 5 h, 1 h, 2 h, 4 h) primary human umbilical vein endothelial cells (HUVECs) , we found that nuclear translocation peak showed up at 2h as with calculated Western blot verification results, indicating that the inventive immuno-fluorescence analysis software can be applied to the quantitative analysis of immuno-fluorescence.

Objective To understand the running status and distribution of water-improving pmjects in Anda city.Methods The running and management of the water-improving projects were investigated and located the position by Global Positioning Systerm(GPS)in Anda city.Results Among 317 water-improving projects,16.09%were either long-term projects or in poor management or had already stopped usage,77 projeets were broken,accounting for 24.29%;all inadequate supply of equipment and pipeline,83 projects had never been started,accounting for 26.18%;now,106 projects were running,accounting for 33.44%.In only 46 projects,the water fluoride concentration was lower than 1.00 mg/L,accounting for 14.51%,as a result 36 thousand people benefited.Conclusions The running status of water-improving projects was unacceptable,most of them stopped running and endemic fluorosis control was still severe in Anda city.

Aim Powdered injections of luotai consist of total saponins of panax notoginseng(PNS) which protect against ischemia injury from myocardial reperfusion injury.Methods ISO-induced acute myocardial ischemia model in rat was made, which decreased S-T sigments in ECG.Luotai after intravenous injection or oral can protect against S-T sigment significant reduction and ∑ST after ISO induced acute myocardial ischemia .Results Luotai 50 mg?kg-1 and 100 mg?kg-1 significantly inhibited S-T sigment decreases. Conclusion Luotai protect ISO induced acute myocardial ischemia and has dose-dependent effect.This ISO-induced acute myocardial ischemia model in rat has some significant advantages,for example,higher stability, good duplication, quickly filtrates, easily masters.

Objective To investigate the inducing effects of selenium dioxide(SeO2 ) on the apoptosis in human cervical carcino-ma cell line Hela and its influence on the expression of apoptosis-related proteins caspase-3 and P53 .Methods Hela cells were trea-ted with different concentrations of SeO2 for 24 h in vitro ;the morphological changes of Hela cells were observed by the optical mi-croscope;the influence of SeO2 on the cell proliferation and vitality was examined by the MTT assay ;the flow cytometry was em-ployed to detect the cell apoptosis rate ;the expressions of caspase-3 and P53 proteins in Hela cells were determined by the Western blot analysis .Results Under the optical microscopy ,SeO2 generated the obvious influence on the cell growth morphology ,a large number of cells became rounded and shrunken ,and lost the normal form ,while the adherence cell number was evidently decreased and the proliferation was slowed down ;the MTT results showed that SeO2 markedly inhibited the cell proliferation and viability in a dose-dependent manner ,in which ,the cell apoptosis rates induced by the 0 ,1 .875 ,3 .750 ,7 .500 ,15 .000 and 30 .000 μmol/L con-centrations of SeO2 were 3 .12% ,30 .56% ,33 .42% ,37 .50% ,45 .43% and 69 .38% respectively ,which revealing the obviously in-creasing trend;the Western blot assay revealed that SeO2 could up-regulate the caspase-3 and P53 levels ,and reached the peak value at the concentration of 7 .500μmol/L .Conclusion SeO2 could induce the cervical cancer cell apoptosis possibly by up-regulating the expressions of caspase-3 and p53 in Hela cells .
