With the improvement of life conditions, obesity has become a factor that impairs the health of the people. From 1997 to 1998, the author had treated 60 cases of simple obesity with acupuncture and obtained satisfactory results. The results of treatment are reported as follows.展开更多

However, the commonly used gear steels which are microalloyed by Al are not suitable for high temperature carburization due to abnormal grain coarsening. The gear steel 20CrMnTiNb, which is microalloyed with 0. 048% Nb and 0. 038% Ti, has been compared with the gear steel 20CrMn in terms of microstructure in the case of hardened layer and in the core after carburizing at 1000 ℃ for 4 h and mechanical prop- erties after carburizing and pseudo-carburizing. The results indicate that the fine austenite grains exist in the carbu- rized case of 20CrMnTiNb steel, while there is abnormal coarsening and duplex grain structure in the case and core of steel 20CrMn. The average prior austenite grain sizes are 19.5 and 34.2 μm for the steels 20CrMnTiNb and 20CrMn, respectively. In addition, the mechanical properties of 20CrMnTiNb steel are superior to those of 20CrMn steel. In particular, the HV hardness of the former is higher than that of the latter by about 40--70 in the range of less than 0. 7 mm in depth. Therefore, the steel 20CrMnTiNb is suitable for high temperature carburization.展开更多

The results showed that Zhu Yu Hua Tan Tang plus general treatment can better improved the conscious state of the patients than western medicine, and it can make the intracranial pressure drop clinically by 40.44%. The intracranial pressure-lowering effect of Zhu Yu Hua Tan Tang, though slow, is smooth and long-lasting without any rebound phenomenon, as compared to those of mannitol. Similar results were found in animal experiments, but the intracranial pressure-lowering amplitude of Zhu Yu Hua Tan Tang was stronger than that of mannitol. The difference between the clinical and experimental results needs to be further studied.展开更多
