Abstract
Prior to translating Tanjur to Mongolian (1749), "Merged Garahyn Oron" (1742) was written for the
translation work to translate terminology of Buddhism from Tibetan to Mongolian and clarify the
writing style. The woodblock of "Merged Garahyn Oron" Tibetan-Mongolian dictionary was created
in 1924 in Aga Datsan of Buryatia by the initiative of the Institute of Literature and Scripts. The dictionary is a unique masterpiece that significantly influenced the national philosophy, development
of scientific disciplines and the great achievements of the Oriental people.
As a result of the research, we compiled 54 complicated and synonymies words from "Field of Medicine" in "Merged Garahyn Oron" dictionary and translated as well as explained each word, thus,
providing an opportunity to study traditional medicine with rationale, enrich the traditional medical
education materials and to put the interpreted words into research circulation in addition to using
in traditional medicine theory and pharmacology. Furthermore, traditional Mongolian medicine has
developed a comprehensive medical science system with unique terminology resulting from cognitive development of Mongolians and has been increasingly developing and utilized in day-to-day
medical care.

Objective To study the corrosion-fatigue properties of a novel low modulus Ti-3Zr-2Sn-3Mo-25Nb(TLM)titanium alloy subjected to simulated body fluid(SBF).Methods Ti-6Al-4V(TC4)alloy was used as the control group.The electrochemical corrosion polarization curves of the two titanium alloys were measured in SBF.The pre-corroded TC4 and TLM titanium alloy samples were subjected to rotational bending fatigue tests.The loading stress amplitude and fatigue fracture cycle relationship was established using the experimental data,and the stress life curves were drawn.Subsequently,the fracture mechanism was analyzed by analyzing the corrosion fatigue micro-fracture morphology of the sample,and fatigue analysis on the titanium alloy sample was then conducted combined with the finite element software.Results The self-corrosion potential of the TC4 titanium alloy under stress annealing was lower than that of the TLM titanium alloy after heat treatment.The TLM titanium alloy was most sensitive to changes in cyclic stress.A comparison between the simulation and experimental results showed that the TC4 titanium alloy under stress annealing had a higher fatigue strength and stronger resistance to crack propagation than the TLM titanium alloy did after heat treatment,whereas its corrosion resistance was the opposite.Compared to the specimens without pre-corrosion treatment,the brittleness of the TLM titanium alloy increased,and its fatigue performance decreased after pre-immersion in SBF.Conclusions Through comparative analysis,the reliability of the test results proved to be high,and the COMSOL finite element software could effectively predict the fatigue life of titanium alloy materials.

Objective To evaluate the biomechanical effects of lateral meniscus posterior root (LMPR) tears fixed at different suture positions, so as to investigate the optimal suture method for repairing LMPR tears. Methods Eight fresh cadaveric knees were used. Each knee was tested under 6 conditions: intact knee, ruptur of LMPR, suture of LMPR to the center point of root insertion, suture of LMPR posterior, interior and later 5 mm to the center point of root insertion, respectively. The peak contact pressure, the average contact pressure and contact area were evaluated using a Tek-scan sensor positioned between the meniscus and tibial plateau, under 1 kN compressive loading, at 0 degree knee extension. Results In the lateral compartment, the average contact pressure and peak pressure significantly increased under rupture of LMPR compared with the intact state (P<0.01), and the contact area decreased significantly (P<0.05). For LMPR tears fixed by four different suture methods, both the average pressure and peak contact pressure reduced, and the contact area increased. The average contact pressure, peak pressure and contact area were closer to the knee joint in the intact state when the suture positions of LMPR tears was posterior 5 mm to the center point of root insertion (P<0.05). In the medial compartment, there were no significant differences in contact pressure, peak contact pressure and contact area with the knee joint at 0 degree (P>0.05). Conclusions The average contact pressure, the peak contact pressure and the contact area between the lateral meniscus and the tibial plateau changed obviously due to the LMPR tears. When the suture position was 5 mm lateral to the center point of root insertion, similar biomechanical function with the intact knee could be obtained.
