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.

Self-cloning is a favorable technique in modification of industrial microorganisms especially food microorganisms because of its bio-safety. A survey and outlook of research in breeding of self-cloning industrial brewing yeast were introduced in this study.

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.

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 explore the causes of subclinical hypothyrodism in children and the effects of the interventional therapy with thyroixine on the course of it.Methods Two hundreds children with subclinical hypothyroidism were measured for thyroglobulin antibody(TGAb),thyroid microsomal antibody(TMAb) in the blood serum,examined by colord Dopplor ultrasonic,examined by fine needle aspiraton cytology of the throid and measured the rate of 131I absorbed by thyroid in order to find out the causes of the disease.Two hundreds cases were randomly divided into two groups on the base of the cause of diseases,treatment group 100 cases and control group 100 cases.The treatment group were treated by throxine 25-75 ?g/d and the therapeutic dosage were chosen with the normal value of free triiodothyronine(FT3),free thyroxine(FT4)and high sensitive thyrotropin(sTSH) in the blood serum .After one year thyroxine therapy were stopped.Thyroid function was examined 6 months later after stopping the thyroxine.Results Among all of the causes of subclinical hypothyroidism in children,Hasgumoto′s thyroiditis accounts for 56%,simple goiter accounts for 26%,antithyroid drug accounts for 6%,the lack of thyroxine substitution therapy on the hypothyroidism accounts for 5% and undefined causes accounts for 7% .The thyroid function could keep normal for 1 year with an alternative therapy with thyroxine on subclinical hypothyroidism in children.Half a year later after stopping thyroxine,the thyroid function turned normal in most of the children.There were obvious differences in the ratio of cure and the ratio of effectiveness between treatment group and control group (t=20.2,3.2 Pa
