Objective To design a Chinese phonetic laboratory system for clinical blood and urine analysis with Chinese pronunciation. Methods The database/table for saving data of patients is established on the basis of Microsoft Access 2000. The Windows Chinese speech function API is used for Chinese pronunciation. The codes of all objects are translated to an executive file which is set up with Visual Basic 6.0 tool kit. Results All data received from 100,000 samples are saved without error in the program running. The Chinese pronunciation is clear. Conclusion This Chinese phonetic laboratory system is effective and flexible in managing the data from blood analyzer and urine analyzer, which helps to improve the standardization of laboratory data report in Out-patient Department.

Schwannomas of the vagus nerve (SVN) and schwannomas of the cervical sympathetic nerve (SSN) are the two most common schwannomas in the carotid space. Because schwannomas are asymptomatic, moreover, the vagus nerve and the cervical sympathetic nerve have adjacent anatomical location, it is diffcult to differentiate SVN or SSN. In addition, the current surgical treatment of schwannomas still remains controversial. This article summarized the studies on SVN and SSN, and meanwhile discussed the advances in the diagnosis and management of the disease.

By reviewing name, type, function and indication of Chinese herbTing-Li-Zi (Lepidii seu Descurainiae) in literatures, there were northernTing-Li-Zi and southernTing-Li-Zi from Song dynasty. It was also known that northernTing-Li-Zi has strong effect and southernTing-Li-Zi had moderate effect. However, there was no strict classification between two types in current clinical practice. The disease prevention and treatment effect of Chinese herbs were depended on their internal features. Disease treatment must be based on syndrome differentiation with corresponding selection of herbs to achieve desired results. Therefore, it is necessary to combine properties with actions in the study of Chinese herbs to provide guidance in clinical practice.

Objective To study the effect of cold and heat treatment on metastasis and the peripheral blood immune response in patients with breast cancer. Methods A total of 124 breast cancer patients were randomly di-vided into a hot and cold therapy group and a control group, each of 62. Both groups were given conventional surgical resections, and the hot and cold therapy group was given cooling and heating physical therapy for one month before the operation. The efficacy of the treatment and the patients′ spiritual state were compared after the treatment. The effect on lung metastases was evaluated using tomographic images of the chest, and the changes in immune cell levels in the peripheral blood were detected using flow cytometry. Results After the treatment, the remission rate (54.8%), spiritual life ratings on the Karnofsky scale and the area of lung cancer nodule transfer were significantly better in the hot and cold therapy group than in the control group. Twelve weeks after the treatment, the percentage of MDSCs in the control group patients was 72.5%, significantly higher than the 5.3% of the therapy group. The CD4+and CD8+ T cells were 2.2% and 1.8%, significantly lower than the 26.7% and 13.9% of the control group. Con-clusion Cold and hot therapy before a mastectomy can effectively inhibit the metastasis of breast cancer and promote patients′physical rehabilitation and spiritual life. It may regulate the microenvironment of their immunosuppression and stimulate antitumor immunity.

Objective To establish the normal reference ranges of peripheral blood CD4 and CD8 lymphocytes for the healthy population in Tianjin. Methods 366 samples were recruited from among local physical examination adults and their absolute and proportional values for the ranges of CD4 and CD8 lymphocytes were detected by quantitative flow cytometry with fluorescence labeled antibodies. Results Mean absolute values were (860.27?255.15) cells/?l for CD4 T cells,(671.60?371.39) cells/?l for CD8 T cells and (1.44?0.62) for CD4/CD8 ratio; and the proportional values were (37.05?7.42)% for CD4 T cells,(28.42?7.46)% for CD8 T cells. Our results showed no differences between gender and age on CD4 T cell counts among the healthy adult population in Tianjin. Conclusions There is difference in CD4 T lymphocyte counts in different areas.

Objective To develop a bar code management system for two-way communication between XE-2100 hematology analyzer and LIS.Methods The relevant databases/tables were set based on PowerBuilder 7.0.The bar code ActiveX MSBCODE9.OCX was used for creating bar codes from patient information and test item information.Codes of all objects were translated to an executive file and DLL files.Results The results showed that the bar code was clear with high discernable rate,stable two-way communication and safe data storage.As the only identifier for specimen,the bar code improved work efficiency and management level,and avoided errors in sampling procedure.Conclusion The application of bar code technique to clinical hematology examination normalizes the workflow and provides a new mode for automatization and standardization management.

Objective To develop a self-help report printing system for management of inspection data and improvement of inspection workflow. Methods The self-help report printing system was compiled based on LIS with ORACLE database management system and was coded with PowerBuilder9.0 development kit. Results The information exchange in self-help report printing system and LIS are implemented successfully, and can print out inspection report with electronic signatures. Conclusion The self -help report printing system simplifies the reporting process and improves work efficiency through application in hospital.

This paper introduces such information of a urinary sediment diagnostic system and its data management system saving data directly from urine analyzer and microscope as its hardware organization and software design.With the performances of easy tooperate and low cost,the system can be applied toclinical urine diagnosis and togenerating standardized reports,whose data management system has high security and accuracy for saving data,strong anti-interference capability,reliable performance,noerror in proceeding and Chinese interface.

Objective To perform the comparative analysis on the test results acquired from three different types of hematology analyzers ,to explore their results comparability or whether their deviations being within the allowable range .Methods The 30 d in‐ternal quality control results collected from the three types of analyzers ,Sysmex XE2100 ,Sysmex XN3000 and Sysmex XT4000i , were analyzed and analyze .The XE2100 hematology analyzer with excellent results in repeatedly participating in the national exter‐nal quality control assessment was taken as the reference instrument ,while the Sysmex XN3000 and Sysmex XT4000i analyzers served as the contrastive instruments .Four blood samples from different patients with high ,medium and low values were randomly selected and detected for 5 d .The results of white blood cell(WBC) ,red blood cell(RBC) ,hematocrit(HCT) ,hemoglobin(HGB) and platelet(PLT) were performed the comparative analysis .Then the accuracy and comparability of the detection results were judged by F test ,regression equation and correlation coefficient .Results The detection result of WBC ,RBC ,HCT ,HGB and PLT had no statistical differences among three instruments (P> 0 .05) .The correlation of various indexes had close correlation (r≥0 .975) .The deviations conformed to the related requirements with comparability .Conclusion When conducting detection by multi‐ple instruments ,the quality control of experimental instrument should be paid attention to ,the different detection instruments should be conducted the calibration and comparison at regular intervals for ensuring the accuracy and consistency of detection re‐sults ,thus better serve clinic .
