Metastatic epidural compression of the spinal cord is a significant source of morbidity in patients with systemic cancer. With improvment of oncotheray, survival period in the patients is improving and metastatic cord compression is en- countered increasingly often. Surgical management performed for early circumferential decompression for the spinal cord com- pression with spine instability, and spine reconstruction performed. Patients with radiosensitive tumours without spine instabili- ty, radiotherapy is an effective therapy. Spinal stereotactic radiosurgery and minimally invasive techniques, such as vertebro- plasty and kyphoplasty, percutaneous pedicle screw fixation, radiofrequency ablation are promising options for treatment of cer- tain selected patients with spinal metastases.

Microbiology experiment existing independently from microbiology theoretical curriculum is an indispensable compulsory course in contemporary life science. This article presents the principle applied by the National Excellent Microbiology Course teaching group in Nankai University, which is to strengthen the undergraduates’ basic skills of conducting microbiology experiments. With an aim to enhance the core competitiveness of the undergraduates, we have established the three-level experimental contents. A new multilevel teaching pattern focusing on basic skill training as the cornerstone has been applied to enhance the overall competences of the students and to stimulate their innovation abilities. Students’ experimental accomplishment will also be taken into consideration when their experiment results are evaluated, which helps to standardizing their research ethics.

OBJECTIVETo explore syndrome and treatment laws for treating diseases of the pulmonary system by establishing database based on clinical works by modern famous veteran doctors of Chinese medicine (CM).

METHODSClinical experience and literature of medical records in clinical works by modern famous veteran doctors of CM were taken as data source. Database was established by fields and program design. On these bases, data mining methods such as frequency analysis, cluster analysis, factor analysis, and correlation laws were performed in syndrome and treatment laws for treating diseases of the pulmonary system.

RESULTSEstablished were database capable of literature searching, information statistics, data mining of modern famous veteran doctors of CM. A total of 34,414 data were input, including medical records and notes 28,045 items (81.49%) and clinical experience 6,369 items (18.51%). In medical records and notes, there were 14,048 items (50.09%) in male and 9,466 items (33.75%) in female, and the ratio of male to female was 1.48:1. There were 4,531 items (16.16%) with no marked gender in medical records or notes. Data mining such as correlation analysis, cluster analysis, factor analysis, correlation laws in more fields could be realized.

CONCLUSIONSMedical records and notes were dominated in data collected in this paper. The prevalence of pulmonary diseases was obviously higher in males than in females. The trend of concentrated manifestations in related fields for pulmonary diseases could be surfed by this database. Diagnosis and treatment laws for treating diseases of the pulmonary system could be found by various adaptive data mining targeting different fields. Multi-variables of symptoms, syndromes, prescriptions, and herbal drugs could be data mined in large samples of clinical literatures.

Objective To investigate the state of drinking water defluorination project in Dagang district and study urinary fluoride levels and detect dental fluorosis of children aged 8 to 12, and to provide scientific basis for prevention and control of fluorosis. Methods Five defluorination projects in rural streets (towns) with highfluoride water and 2 urban water supply projects were choosen to investigate the running status in Dagang district Tianjin in 2009. Five rural and 2 urban schools were choosen to select 100 children aged 8 to 12 (for gender, age matched) in each primary school to study urinary fluoride levels and detection of dental fluorosis. Results A total of 66 defluorination projects in 73 villages were surveyed, among which 61 projects actually worked normally with using rate 92.4%(61/66). Water qualification of all projects could not be ensured due to direct project managers'lack of necessary expertise. In 2009, water qualification rate were 39.3%(24/61 )among the project normally used,with highlighted problem of biological pollution. A total of 490 children aged 8 - 12 in 5 rural towns were surveyed,dental fluorosis rate were 90%(441/490), and dental fluorosis index were 1.82. A total of 207 children aged 8 - 12in 2 urban areas were surveyed, the detection rate of dental fluorosis was 49.8%(103/207), and dental fluorosis index were 0.86. The urinary fluoride level of 230 children aged 8 - 12 in the 5 villages were surveyed. The Range of geometric mean of urinary fluoride were 1.82 - 2.70 mg/L. The urinary fluoride of 102 children aged 8 - 12 in the 2 urban area were surveyed. The Range of geometric mean of urinary fluoride were 1.53 - 1.72 mg/L. Conclusions There was phenomenon of high coverage, low utilization rate and less water consumption in the villages of Dagang district, Tianjin drinking water defluoridation projects, thus the health effects of the projects was minimum.Significant health effects is found in the defluorination projects in the urban areas with high coverage and high utilization rate. Studying new water improvment methods and new forms of water supply system is urgent for solving the problems met in the ineffective water defluorination project.
