Objective To analyse the efficacy of hysteroscopic resection and norethisterone in abnormal uterine bleeding.Methods 38 cases of submucos myoma of uterine body,26 cases of endometrium polyps and 16 cases of complex hyperplasis of endometrium were treated with hysteroscopic resection,and all the cases take norethisterone for one month before hysteroscopic resection and go on taking norethisterone for three months after operation.All the cases were followed up with the improvement of symptoms and the chang of uterine cavity.Results All the cases were followed up for 3~18 months after operation.The efficacy of submucous myoma of uterine body was 92.10%(36/38) and that of endometrium polyps was 84.61%(22/26) and that of complex hyperplasis of endometrium was 93.75%(15/16).Conclusion The treatment of hysteroscopic resection and norethisterone in submucous myoma,endometrium polyps and complex hyperplasis has advantages of satisfied results,slight trauma,fast recovery and fewer recurrence relapse.

Objective To explore the protection effects of the reduced form of nicotinamide-adenine denucleotid(NADH) on cardiac fibroblasts apoptosis induced by hydrazine in vitro.Methods Cardiac fibroblasts isolated from neonate rats were divided into four groups.In NADH pretreatment before hydrazine treatment group,the cardiac fibroblasts were cultured first in the medium containing 400?g/ml NADH for 2 hours,and then cultured in the medium containing 400?g/ml NADH plus 2mmol/L hydrazine for 72 hours;in hydrazine treatment group,the cardiac fibroblasts were cultured first in normal medium containing 400?g/ml NADH for 2 hours and then cultured in the medium containing 2mmol/L hydrazine for 72 hours;in control group,the cardiac fibroblasts were cultured only in normal medium for 72 hours;and in NADH pretreatment control group,the cardiac fibroblasts were cultured in medium containing 400?g/ml NADH for 72 hours.After the treatments mentioned above,the changes in nuclear of apoptotic cardiac fibroblasts as stained by Hoechst33258 were observed under fluorescence microscope,the apoptotic and necrosis rates of cardiac fibroblasts stained by AnnexinⅤ/PI were assayed by flow cytometry,the mitochondria membrane potential of cells stained by rhodamine123 was also assayed by flow cytometry.Results Hydrazine could induce apoptosis of the cardiac fibroblasts.After NADH pretreatment,the number of apoptotic cardiac fibroblasts with pyknosis of nuclear was lowered,the rates of apoptosis and necrosis decreased,and the mitochondria membrane potential of cells was elevated.Conclusion NADH pretreatment could reduce the apoptosis induced by hydrazine by improving the function of mitochondria.

Objective To investigate and evaluate the quality of Cortex Ilicis Rotundae medicinal materials in Chinese herbal medicine market. Methods Twenty-two batches of Cortex Ilicis Rotundae commercial medicinal materials were identified and analyzed by characteristic identification, microscopic identification, thin layer chromatography ( TLC) and extractives determination, and the contents of syringin and pedunculoside were detected by high performance liquid chromatography (HPLC) according to the Chinese Pharmacopoeia published in 2010. And then the quality of the medicinal material of Cortex Ilicis Rotundae was evaluated comprehensively. Results Of the 22 batches of Cortex Ilicis Rotundae medicinal materials, 2 batches were adulterated with fake Cortex Ilicis Rotundae, one batch was inferior and was mixed with counterfeits, and the quality of 12 batches was also poor. Conclusion At present, the quality of Cortex Ilicis Rotundae medicinal materials in Chinese herbal medicine market varies greatly, and adulterants and the inferior are common.
