OBJECTIVE: To analyse oily constituents of Meconopsis punicea Maxim. METHOD: The oily constituents were analysed and identified by GC-MS. RESULTS: The sixty-three constituents were isolated and the forty-seven of that were identified, making up 74.6% of the total constituents. Ester compounds accounted for 57.5% of the identified compounds. The main constituents were ester octadecnate. CONCLUSION: Ester octadecenate has high biological activity, which agrees with curative effect of the plant.

From 2004 to 2013,Peking Union Medical College had implemented technology innovation plans to build 12 innovation teams funded by Ministry of Education.This paper made statistical analysis of the results and achievements of the team building initiatives and put forward new ideas and measures for future development.

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.

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

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.

Chest contusion is the soft-tissue injury disorders that the external violence directly destroys the chest wall and the soft tissues, causing chest pain, fullness, and symptoms aggravate when the chest moves. Chinese medicine showed many treatments with clinical efficacy. Therefore, Chinese medicine has been widely used in clinics. This paper was to review the research progress of Chinese medicine treatment for chest contusion.

Objective To prove that valve sparing aortic root reconstruction may have an impact on the outcome and longevity of the repair for patients with acute type A aortic dissection.Methods Clinical data of 98 consecutive AAAD patients undergoing the valve sparing aortic root reconstruction were analyzed.The postoperative follow-up and the clinical effect of the procedure were retrospectively analyzed.Results Pre-operative grade of aortic insufficiency was(2.3 ± 0.5), CPB-time was (217.8 ± 43.1)min, aortic cross clamp time was(142.7 ± 37.4)min and stay on ICU (11.1 ± 5.7) days, while hospitalisation was(14.3 ± 3.2) days.8 patients(8.2％) died peri-operatively.None of the early deaths were valve-related.Rethoracotomy rate was 3.1％.All patients followed up(19.3 ± 7.6) (6-68) months.Survival at 1 year was 90.8％.Freedom from valvular reoperation was 97.9％ at 3 years.At last investigation, mean grade of aortic insufficiency for AADA was 0.5 ± 0.3 (0-3).Conclusion Regardless of the underlying indication, the aortic valve preserving reimplantation technique can be performed with favourable functional results.

Cardiac surgery carried out on cardiopulmonary bypass(CPB) in a pregnant woman is associated with poor neonatal outcomes although maternal outcomes are similar to cardiac surgery in non-pregnant women.Most adverse maternal and fetal outcomes from cardiac surgery during pregnancy are attributed to effects of CPB.The CPB is associated with utero-placental hypoperfusion due to a number of factors,which may translate into low fetal cardiac output,hypoxia and even death.Better maternal and fetal outcomes may be achieved by early pre-operative optimization of maternal cardiovascular status,use of perioperative fetal monitoring,optimization of CPB,delivery of a viable fetus before the operation and scheduling cardiac surgery on an elective basis during the second trimester.
