Objective To evaluate the clinical efficacy of oral taking traditional Chinese medicine with functions of tonifying kidney, nourishing blood and soothing liver and external application treatment of premature ovarian failure(POF). Methods 40 patients of deficiency of liver-yin and kidney-yin type POF in Gynecology Department of Xiyuan Hospital CACMS from July 2009 to July 2013 were collected and administrated with traditional Chinese medicine with functions of tonifying kidney, nourishing blood and soothing liver and external treatment for 3 months. The changes of menstruation situation, symptoms and serum sex hormone were compared before and after the treatment. Results ① Menstruation integral were reduced after the treatment, showing a statistical significance compared with those before the treatment(t=5.694,P<0.01). ② Symptoms integral were reduced after the treatment, showing a statistical significance compared with those before the treatment(t=21.828,P<0.01). ③ Serum FSH, LH were decreased and Serum E2 were increased after the treatment,showing a statistical significance compared with those before the treatment(P<0.05). ④ The total effective rate was 92.5%(37/40). Conclusion Traditional Chinese medicine with functions of tonifying kidney, nourishing blood and soothing liver are effective for treating POF. These methods had proven to improve ovarian function by decreasing high level of FSH and LH, whereas enhancing the estrogen level, and therefore promote menstruation cycle.

Objective The biological effects of BMP3 on osteosarcoma were investigated by treating human osteosarcoma cell lines MG63,and U2OS with human BMP3(hBMP3).Methods Osteosarcoma cells in experimental groups were respectively treated with AdBMP-3 and rhBMP3-CM,control groups with AdGFP and rGFP-CM,the blank group with neither.Their ability of proliferation,apoptosis,transmigration and differentiation were respectively detected by trypan blue exclusion test,terminal deoynucleotidyl transferase mediated dUTP nick end labeling(TUNEL) and acridine orange-ethidium bromide fluorescent stain(AO/EB),transwell-room and alkaline phosphatase(ALP) activity reagent kit.Results(1) All the indexes detected were not significantly different between two control groups.(2) Compared with control groups,the cell survival rate showed a significant decrease in experimental groups.(3) The apoptosis indexes increased.(4)The number of trans-membrane cell decreased.(5)The activity of alkaline phosphatase increased after treatment with AdBMP3 and rhBMP-3 for 3 days in MG63,5 days in U2OS.Conclusion hBMP3 inhibit osteosarcoma cells growth and promote bone formation.

Objective The ECG lead II characteristics of Beagle dog, rhesus monkey, Japanese white rabbit and tree shrew were analyzed and summarized to provide reference for drug safety evaluation studies.Methods The ECG lead II of healthy adult Beagle dog, rhesus monkey, Japanese white rabbit and tree shrew were recorded to determine the interval of P, PR, QT ( QTc) , the QRS waves and amplitude of P, R, T waves and the ST shift.Results and Conclusion All the animals had sinus rhythm.All the four species of animals had similar ECG pattern with no particular specific changes, but had some differences of the QRS wave group and T wave.The amplitude of P and T waves in Japanese white rabbit was smaller, and the heart rate of tree shrew was faster than that of the other species of animals.The ECG leadⅡdatabase of the Beagle dog, rhesus monkey, Japanese white rabbit and tree shrew is established.

Objective To analyze the situation of life sciences and medical research involving human subjects conducted in a public hospital in Ningxia from 2020 to 2022 and explore the problems in the current management of such research and pro-vides suggestions for improvement.Methods Data were collected from research project application documents,task assign-ments,progress reports,final reports,and statistical tables of clinical drug trials conducted in the hospital from 2021 to 2022.Statistical analysis was performed on the life sciences and medical research involving human subjects.Results The number of research projects involving human subjects in the hospital increased annually from 2020 to 2022,accounting for more than 50%of the total projects.Over the three years,the sample size exceeded 100,000,and the number of projects with a cumulative collec-tion of more than 3,000 individuals showed an upward trend.However,the project registration rate was less than 10%.These types of research involve a large number of biological samples and information data,which have research value.However,re-searchers lack awareness of project registration,highlighting the need for greater attention from the hospital.Conclusion It is a trend to explore the medical value of this type of research in depth.The hospital should closely follow relevant national and re-gional policies,conduct dynamic monitoring and evaluation,and enhance supervision and management capabilities as a key factor in protecting biological samples and information data.This study also provides reference for other public hospitals in carrying out related regulatory work.

OBJECTIVE: To investigate the effect of human bone morphogenetic protein (hBMPs) 2/3/6 and 12 on osteosarcoma cell UMR106. METHODS: Adenovirus-BMP2/3/6 and 12 (AdBMP2/3/6 and12) were used to treat the cell line. Their proliferation, apoptosis, and transmigration were detected by Trypan blue exclusion test, TdT-mediated biotinylated-dUTP nick end labeling (TUNEL), acridine orange-ethidium bromide (AO/EB) double fluorescent dye staining, and transwell-room test, respectively. The alkaline phosphatase (ALP) activity was detected to reflect the differentiation of tumors. RESULTS: Compared with the control groups, the cell survival rate of the experimental groups treated with AdBMP2/3/6 and 12 showed a significant time-dependent decrease (P<0.01). The apoptosis indexes were increased significantly (P<0.01) and the results from TUNEL and AO/EB method were consistent. The cell numbers of transmembrane significantly decreased at 24,48, and 72 h (P<0.01). AdBMP2/3/6 and 12 treatment enhanced the activity of ALP activity from day 3 and this effect might still be observed up to day 9 of the treatment (P<0.01). CONCLUSION hBMPs2/3/6 and 12 can inhibit the proliferation and transmigration, and induce their apoptosis and differentiation in osteosarcoma cell line UMR106.
