Objective A solution of serial communication in Multi-Axis Controller which uses programmable multi-axis controller (PMAC) as down processor and PC as up processor is introduced. By the PComm32.dll provided with Delta Tau Data Systems Inc., the serial communication between PC and PMAC is realized based on .NET. Methods In order to realize the programming techniques of serial communication, a new method that managed codes invoked the unmanaged codes in Common Language Runtime environment by using Platform Invocation Services was adopted. The serial communication program was designed by using the program language C#. Besides the single axis locomotion,the debugging procession of the multi-axis joint locomotion was also recounted based on the five-DOF robot. Results The results indicated that the serial communication between PC and PMAC was completely realized. Conclusion The developed serial communication software module is of good correctness, stability and reliability, and also shows that the software is convenient and easy to use, which can accord with system requirements.

This article introduced the experiences of nongovernmental capital running hospitals in US,Germany,India and Israel and put forward some suggestions that need to be considered in China, such as innovating supply model of health care service,treating social capital running hospitals equally and strengthening supervision.

Objective To study the expressions of phosphatese and tensin homolog deletedin chromosom ten (PTEN),Fas/FasL system and matrix metalloproteinnases-2 (MMP-2) in human gastric cancer.Methods Seventy-five cases of gastric carcinoma were selected from paraffin wax embodied specimens with full clinicopathological data,and another 15 cases of normal gastric mucosa specimens were selected as the control group.SP immunohistochemistry was used to measure the expressions of PTEN,Fas/FasL and MMP-2 in them.The data was statistically analyzed by ?2 test and relative analysis.Results The expressions of PTEN,Fas/FasL and MMP-2 were correlated with the lymphatic metastasis,degree of infiltration,clinical TMN stage and pathological histological differentiated degree of gastric cancer (P

Qi in TCM is the most essential substance that makes up the body and maintains life activities. All vital substances in the body are transformed by constant motion and changes of qi. Qi in TCM mainly means full of functions. What is the basic material attribute of qi? We don't have a systematic study on it. Therefore, we combined the achievement of modern medicine, and explored further from the origin, functions, pathogeneses, and therapies of mitochondria and qi. Surprisingly, we found out that the origin of mitochondria was similar to that of qi. They are tiny substance constituting the human body. Secondly, the function of mitochondria is similar to that of qi. When the disorder of qi and mitochondria occurs, similar vital signs occur or the same reactions occur. These results suggested that the basic material attribute of qi might be mitochondria.

Objective To compare the short-term follow-up cu ra tive effect of primary total hip replacement (THR) in treating fresh and old fem oral neck fractures. Methods Double follow-ups with an in terval of 13 months were performed in patients with femoral neck fractures under going THR in our department from January 1997 to October 1999. Results After a follow-up for 37-62 months (mean 44 months), we obtained f ull data of 47 patients [41-77 years old, (61.8?5.22) years old] with preoperative Harris score of 28.40?10.14 and postoperative score of 85.20?7. 91. The Harris score of patients with fresh femoral neck fractures (FFNF) incr eased from 21.60?8.73 preoperatively to 82.50?9.81 postoperatively〔at age of (63.50?5.53) years〕 and that of patients with old femoral neck fracture (O FNF) from 37.70?13.50 to 90.63?5.79, [at age of (58.90?7.81) years]. Of 47 patients, only one case had dislocation once within six weeks postoperative ly during function exercise and recovered after manual reduction. Another one wi th excellent function evaluation was given again internal fixation three years a fter THR because of femoral shaft fracture and obtained satisfactory recovery. N o complications were found in other patients. The mean Harris score in patients with OFNF was significantly higher than those with FFNF ( P
