PURPOSE To investigate the clinical value of the T-antigen monoclonal antibody method on screening of large intestinal carcinoma. METHODS The T-antigen monoclonal antibody method and the galactose oxidase method were simultaneously used to detect T-antigen in large intestinal mucus of 207 cases. RESULTS There was not obvious difference in screening value between the T-antigen monoclonal antibody method and the galactose oxidase method, for that they had similar sensitivity (69. 2%, 67. 3%) and specificity (64. 2%, 65. 6%) in diagnosis of large intestinal carcinoma. CONCLUSION The T-antigen monoclonal antibody method was convenient, eligible and valuable on screening of large intestinal carcinoma.

Objective To analyze the practical experiences of design and its clinical application of custom-made tumor prostheses of knee. Methods A retrospective study of 41 cases of distal femur or proximal tibia tumors treated surgically from June 1999 to October 2002, was carried out. In the study, there were 29 males and 12 females aging from 11 to 69 years with an average of 35.0 years. The location of tumors were at distal femur in 23 cases and 9 cases at proximal tibia, of which 15 were osteosarcoma, 13 giant cell tumor, 3 chondrosarcoma, 5 solitary metastatic bone tumor, and 1 each of fibrosarcoma, malignant fibrohistocytoma, Ewings sarcoma, small round cell sarcoma and syndesmofibroma. The custom-made semi-constrained knee prosthesis with femoral or tibial component was implanted after extra-capsular resection of the tumor bone segment. A special femoral component with elongated construction was used in an 11-year old case for further femur lengthening. Resection of femoral artery involved by tumor and reparation by great saphenous vein was performed in one case. Results The operations of the 41 cases were all smoothly performed. 33 cases were followed up from 8 to 37 months with an average of 20.2 months. The daily life ability was recovered in 3 months after the operation. Among them, no loosening or failure of the prostheses was found, and local recurrence was found in 2 cases and distant metastasis in 3 cases. The design of knee prosthesis could provide some proper internal/external rotation and adduction/abduction movements accompanying with the flexion and extension of the knee joint without affecting the stability of the joint. For the case of proximal tibia tumor, a special design and surgical technique was developed to provide the reconstruction of patellar ligament insertion with rather good results; and the recovery of knee extension and stability were satisfied. Conclusion The custom-made semi-constrained tumor prosthesis of knee could be used as an effective method for the limb-savage management either the distal femur or proximal tibia tumor cases.

Objective To evaluate the efficacy of Shikani laryngoscope-guided nasotracheal intubation in patients undergoing maxillofacial surgery. Methods One hundred ASA Ⅰ or Ⅱ patients with body mass index ＜25 kg/m2 , aged 18-64 yr, undergoing maxillofacial surgery under general anesthesia requiring nasotracheal intubation were included in this study. Fifty patients without anticipated difficult airway in preoperative assessment were randomly divided into 2 groups ( n = 25 each): Macintosh luyngoscope group ( group M ) and Shikani Optical Stylet (SOS) group (group S1 ). The other 50 patients with mouth opening ＜ 3 cm but without difficult ventilation by mask were randomly divided into 2 groups ( n = 25 each): fiberoptic bronchoscope group (group F) and SOS group (group S2 ). Tracheal intubation was performed under the guidance of laryngoscopes after induction of anesthesia, and then the patients were mechanically ventilated. The degree of glottis exposure and epistaxis was evaluated. The rate of successful intubation, rate of successful intubation at first attempt, intubation time and complications were recorded. Results Compared with group M, the rate of successful intubation, rate of successful intubation at first attempt, and degree of glottis exposure were significantly increased, the intubation time was significantly shortened, and the degree of epistaxis was significantly decreased ( P ＜ 0.05), but no significant change was found in the complications in group S1 ( P ＞ 0.05). Compared with group F, the intubation time was significantly shortened ( P ＜ 0.05), but no significant change was found in the rate of successful intubation, rate of successful intubation at first attempt and complications in group S2 ( P ＞ 0.05). Conclusion Shikani laryngoscope can expose glottis better and the rate of successful intubation at first attempt is higher, thus it is more suitable for nasotracheal intubation in patients undergoing maxillofacial surgery.

Objective To study the protective effects of the polyphenols of vitis amurensis Rupr(PVAR) on oxidative damage in rats caused by chronic alcohol intakes.Methods Forty male Wistar rats were divided into 4 groups according rats' weights: normal control group,alcohol injury group(the rats were treated with 10 mL?kg-1 33% alcohol via i.g);PVAR group(after ingesting 200 and 400 mg?kg-1 PVAR,the male rats were treated with 10 mL?kg-1 33% alcohol via i.g).After 8 weeks,the concentrations of malondialdehyde(MDA),reactive oxygen species(ROS),glutathione(GSH) and the activities of SOD and heme oxygenase-1(HO-1) in rat liver tissues were measured.The activities of serum glutamic-pyruvic transaminase(GPT) and glutamic oxaloacetic transaminase(GOT) in rats were measured.Results Compared with alcohol injury group,the concentrations of MDA,ROS,GPT and GOT were decreased significantly(P

0.05).Conclusion The local relapse rate and the survival rate within 3 years has no significant difference between patients with lower rectal cancer of Duck stage A after sphincter-preserving surgery and Miles surgery.

Objective:To investigate the effects of N-acetylcysteine(NAC)on the number of Clara cells and secretion of Clara cell16000(CC16)protein in murine asthmatic model.Methods:The murine asthmatic model was established by sensitiz-ing and challenging BALB/c mice with ovalbumin(OVA).Thirty mice were divided into control,asthmatic and NAC groups (n=10).

Methods:1 13 patients,aged 12 ~28 years,with peg-shaped upper lateral incisors were included,lateral cephalograms were taken and analyzed cephalometrically.Data were statistically analysed.Results:The sagittal facial patterns were skeletal Class Ⅰ(40.71%),skeletal Class Ⅱ(9.73%)and skeletal Class Ⅲ(49.56%).The vertical skeletal patterns were average vertical type (41.59%),high vertical type(18.58%)and low vertical type(39.82%).SNA,ANB,Ptm-A(mm),U1-SN,L1-NB,UL-EP were smaller(P<0.05)and SNB,PP-GoGn,SN-MP,Y axis,U1-L1,U1-NA,L1-MP and Z angles were increased(P<0.05).Conclu-sion:Patients with peg-shaped upper lateral incisors show Class Ⅲ skeletal pattern with maxillary retrognathia and mandibular prog-nathism.

The paper introduced the background and concepts of municipal trusteeship of district-launched medical institutions, with the trusteeship of women and children′s hospital of Shunyi district as an example.In addition to the main approaches and contributions in improving hospital management, delivery of quality medical resources to primary care, and capacity building, the authors called for the support for standardized healthcare, respect for original hospital culture, and sustained government support to the hospital in question among other points, for reference of further public hospital reform.

Immunohistochemical localization of many sorts of tumor tissues from paraffin sections was studied using the ABC method with the monoclonal antibody secreted by the established two anti-osteosarcoma cell lines. It showed that the OS-McAb1 and OS-McAb2 had a negative reaction on the tested benign tumors and malignant tumors of epithelial tissue. Of the tested malignant tumors of mesenchyma, the antibodies had a positive reaction on some osteogenic sarcoma. They did not cross-react with various normal adult or fetal tissues, indicating that the OS-McAbs had a rather high specificity. They had a certain practical value in the immunopathologic diagnosis of malignant osteogenic tumors.
