The article summarized and analyzed the research fund for doctoral programs at Peking Union Medical College during the 10th and 11th Five-Year period.A further exploration into the fund's management pattern was made and suggestions on how to improve the management were also proposed.

Objective: To analyze the main chemical constituents of traditional Chinese medicine compound Chenxiang Huaqi Pills by using UPLC-Q-TOF/MS technology. Methods: The separation was performed on Phenomenex Kinetex C18 column (100 mm×4.6 mm, 2.7 μm), and the gradient elution of acetonitrile-0.1% formic acid was used as mobile phase at a flow rate of 0.8 mL/min. The data was collected by the positive and negative ion modes using Q-TOF/MS and ESI source. The main chemical constituents of Chenxiang Huaqi Pills were identified according to the exact molecular mass, the cleavage fragments of MS/MS, the literature data, and the reference control. Results: A total of 73 chemical components were separated and identified in Chenxiang Huaqi Pills, including 36 flavonoids, 16 2-(2-phenylethyl) chromones, 7 triterpenoid saponins, 2 sesquiterpene lactones, and 12 other components. Conclusion: This study showed that UPLC-Q-TOF/MS technology provided a simple, rapid, and accurate method for the identification of chemical constituents in Chenxiang Huaqi Pills, which provided a new technology method for the pharmacological basis and quality control of Chenxiang Huaqi Pills.

The Union Youth Science & Research Fund was set up by the Peking Union Medical College (PUMC) using the Fundamental Research Funds for the central universities.Education Ministry's National College Special Fund for Basic Science& and Research drafted and implemented its own management rules.The rules standardize the fund's various aspects including its system construction,project classification,implementation terms,outlay management,and project management.In consequence,the rules promoted the young teachers' research on funded-subjects and improved the management level on scientific research projects.

Objective To study the relationship between endothel in-1 in plasma and TCD in patients with brain injury.Methods We measured dynamically the level of ET-1 in plasma on 33 adult brain injured patients. Cerebral vasospasm was detected by transcranal Doppler sonography (TCD).Results 1.During 6-8 days, 13-15 days after injury,there was a significantly positive correlation between the level of ET-1 in plasma and cerebral vasospasm (r=0.533,P=0.002;r=0.423,P=0.02),especially during 6-8 days after injury. The increase of the level of ET-1 in plasma paralleled paroled with the time of cerebral vasospasm developed. 2.During 6-8 days after injury, the level of ET-1 in plasma of patients with cerebral vasospasm was obviously higher than those without cerebral vasospasm obviously (P

OBJECTIVETo investigate the effects of oral cancer-associated fibroblasts (CAFs) on lymphangiogenesis in oral squamous cell carcinoma (OSCC).

METHODSCAFs and normal fibroblasts (NFs) were obtained from the tissues of patients with OSCC who did not receive radio-chemotherapy before operation. And the CAFs and NFs were isolated by method of tissue block and identified by immunohistochemical staining. The effects of CAFs (group A) and NFs (group B) to human lymphatic endothelial cells (HLEC) were detected by using a 24-multiwell transwell cell culture chamber. DMEM sugar medium was as blank control group. The number of proliferative, migratory, invasive and tubes of HLEC were counted under inverted phase contrast microscope.

RESULTSThe proliferative number of HLEC of group A for 96, 144, 196 h was significantly higher than that of group B and blank control group, group B higher than blank control group (P<0.01). The migratory and invasive number of HLEC of group A for 96 h was significantly higher than that of group B and blank control group, group B higher than blank control group (P<0.01). The number of tube formation of HLEC of group A for 24 h was significantly higher than that of group B and blank control group, group B higher than blank control group (P<0.01).

CONCLUSIONCAFs promote HLEC's proliferation, migration, invasion, tube formation, and these effects are stronger than NFs.

In Scientific Research Institutions,it has great significance of the S&T resources archiving and sharing to promote the deepening reform of S&T system and realize the great leap-forward development of S&T innovation.In this paper,we conduct empirical analysis on the conditions of S&T resources archiving and sharing in a Medical Organization in Beijing.The results show that the S&T resources archiving and sharing in Medical Organization have achieved initial success,however,the achievements are not ideal and the waste and shortage of S&T resources still coexisted.In view of the deficiencies of the idea,system,laws and regulations of S&T resources archiving and sharing,this paper puts forward corresponding countermeasures and suggestions.

Objective To observe the effect of repetitive transcranial magnetic stimulation (rTMS) and functional magnetic stimulation over spinal cord (SC-MS) on motor function recovery after spinal cord hemisection in rats. Methods T10 spinal cord hemisection model was made. The stimulation (5×10 s bursts of 5 Hz at 35% maximal stimulator output, each burst separated by a 2 m interval) was delivered daily, 5 d per week for 2 weeks. The treatment began at 4 d after surgery for rTMS group and SC-MS group. Motor function recovery was assessed with Basso, Beattie & Bresnahan locomotor rating scale (BBB) and the Horizontal Ladder test. The tibialis anterior was surgically removed at 38 d after spinal cord injury for calcitonin gene-related peptide (CGRP) iummunohistochemical staining. Results The scores of BBB and Horizontal Ladder test were significantly more at 17 d after spinal cord hemisection in rTMS group than before treatment and in spinal cord injury group (P<0.05). In SC-MS group, the scores of BBB and Horizontal Ladder Test were significantly more 10 d after SCI than before treatment and in SCI group (P<0.05). The score of Horizontal Ladder test of SC-MS group was more 10 d after SCI than that in the rTMS gourp (P<0.05). The expression of CGRP on motor endplates of the tibialis anterior in rTMS group and SC-MS group were more than those of SCI group (P<0.01). Conclusion rTMS and SC-MS in acute stage can improve the motor function recovery and muscle plasticity after spinal cord hemisection in rats. The magnetic stimulation can facilitate the recovery of motor function after spinal cord hemisection in rats.
