Preparations of cell-free supernatant from Rous sarcoma "?????" were inocu-lated onto the chorio-allantoic membranes (CAM) of the chick embryos of 7--9 days in-cubation. The inoculated portions of the CAM were removed at various intervals from6 hours to 10 days afterwards. The tissues were fixed in Carnoy's solution and werestained with methyl green-pyronin for nucleic acid, Alcian blue-hematoxylin or Alcianblue-alum cochineal for acid polysaccharide and toluidine blue for metachromatic reac-tion. The pathogenesis of the Rous sarcoma of the inoculated CAM and the histo-chemical reaction of the nucleic acid and acid polysaccharide have been followed by his-tological examinations. Recognizable macroscopic lesions consisting of membrane opacity, focal thickening,oedema and discrete nodules in the inoculated CAM appeared from the first day on-ward. Distinctive hemorrhagic lesions and pocks were observed on the 3rd to the 5thday. Tumor masses of different sizes appeared from the 7th to the 9th day. In casethe CAM were inoculated with horse serum-saline, no or only slight reaction was ob-served, and the normal thickness and structures of the CAM were generally maintained. Three successive stages of the Rous sarcoma on the inoculated CAM weredistinguished: (1) Focal ecto-mesodermal proliferation with formation of earlytumor-like nodules; (2) Extreme ectodermal hyperplasia and early mesodermalsarcoma-like proliferation; (3) Ectodermal necrosis and extensive malignant growthof the mesodermal neoplastic cells. The fibroblasts, pyroninophilic round cells andthe ectodermal cells were the main types of cells concerned in the developmentof tumors following infection of the CAM Rous virus. The fibroblasts transformedinto tumor cells and became the most conspicuous elements of the Rous sarcoma. Thepyroninophilic round cells were considered to be belonging to the basophilic myelocyteseries, according to their morphological and staining characteristics. Their possible rolein the tumor infiltration was discussed. The intensity of the nucleic acid in the CAM cells increased along with the increaseof histopathological changes at the inoculated area of the membrane. The possible sig-nificance of their parallel relationship was discussed. Alcian blue staining of the growing tumor tissue demonstrated the presence of acidpolysaccharide reaction in the ground substance. The intensity increased with the increaseof the malignancy of the neoplastic cells. This material is non-metachromatic whenstained with toluidine blue and could be removed by treatment with testicular hyaluroni-dase for 3--5 hours. The mucin present is considered to be of a hyaluronic acid nature.

Objective To evaluate the individuality of patients with primary angle-closure glaucoma and discuss the relation between individuality and glaucoma. Design Questionnaire. Participants 99 patients with primary angle-closure glaucoma and 99 healthy people. Methods Questionnaire were performed with Self-rations Anxiety seal: TH means "Time and Hurry", CH means"Competition and Hostility" and L means "Lit". The questionnaires were compartmentalizied with the scoring of TH+CH and statistical analysis; Score 50-28 means Type A behavior, 27 means Type X behavior, 26-1 means Type B behavior. Main Outcome Measures CH, TH, CH+TH. Results The quantity of primary angle-closure glaucoma in type A behavior group was 49 (64.5%), while the quantity of healthy people was 32 (36.8%). There was obvious difference between two groups (P=0.001). The scoring of TH, CH and TH+CH of primary angle-closure glaucoma patients were higher obviously than those of the healthy one (P

Objective To introduce and analyze the design, manufacture and clinical effect of the casting full dentition splint in treatment of periodontal disease with or without dentition defect. Methods 148 patients with periodontal disease during 1995 to 1998 were treated with casting full dentition splint after a thorough basic periodontal treatment. The patients were composed of 81 men and 67 women aged 40-69y. The patients were followed up for 1 to 3 years after restoration. General effects of the prosthesis were evaluated based on the chief complain of patients, clinical examination and X-ray examination. Results Among 148 patients, 140 (94.59%) were satisfied with the prosthesis and stable periodontal status, 6 (4.05%) were improved, 2 (1.35%) showed no clinical effect. Conclusion Casting full dentition splint can improve the mastication efficiency in periodontal disease patients. It is an effective and reversible therapeutic method on treatment of the periodontal disease with or without dentition defect.

Objective To research the surgical technique and curative effect of the posterior cruciate ligament(PCL) anatomical reconstruction with double-bundle hamstring tendons absorbable interference screw fixation via double-tunnel in femoral under arthroscopy. Methods 24 patients, average age of 32 years ranged from 17 to 42 years old, were treated with anatomical reconstruction of PCL through double-tunnel in femoral and one tunnel in tibia with double-bundle hamstring tendons fixed with absorbable interference screw under arthroscopic. The anterolateral bundle was reconstructed with multistranded autograft semitendinosus tendon grafts and was tightend and fixed, at knee flexion 15?-30?. The posteromedial bundle was reconstructed with multistranded autograft gracilis tendon grafts, and was tightened and fixed, at knee flexion 60?-70?. Results All the patients were followed up for a mean time of 9.4 months (6 months-19 months). All the knee joint motion were in normal range, no exhibition of pain and distinct trauma arthritis. The postoperative posterior drawer test, reverse Lachman test, tibia sags sign and reverse pivot shift test were all negative. The postoperative Lysholm score was (92.7?6.4) points, and the postoperative score increased significantly compared with the preoperative (t=3.12, P

Objective To investigate the effects of Pollen Typhae total flavone (PTF) on INS-1 pancreaticβcell damage induced by palmitic acid ( PA) . Methods INS-1 pancreatic β cells were given long-term induction with PA to establish the impaired cell model, and then were intervened with PTF. Cell viability was determined by tetrazolium salt ( XTT) colorimetry. Results PA impaired the viabilities of INS-1 pancreatic β cells in concentration- and time-dependent manner, and PTF improved the impairment of INS-1 pancreatic β cells induced by PA in concentration -dependent manner. Moreover, PTF showed better improvement on the impairment when the INS-1 pancreatic β cells were impaired more seriously by PA. Conclusion PTF has effects on ameliorating the impairment of INS-1 pancreaticβcells induced by PA for long time.

Objective To investigate the relationship between obesity parameters and obstructive sleep apnea-hypopnea syndrome (OSAHS) in aircrew. Methods A questionnaire survey in aircrew members was performed. Outcome measurement included body height, body weight, neck circumference ( NC), waist circumference (WC), and body mass index (BMI). Those with snoring during sleep and/or Epworth sleepiness scale (ESS)score ≥ 9 were screened with pulse oxygen saturation test during overnight sleep. Those with oxygen saturation decrease index ≥ 10 times/h and suspected OSAHS were tested by polysomnography (PSG). The objects were then assigned to three groups: the OSAHS group,the snore group and the normal group. The relationship between obesity parameters and OSAHS was analyzed. Results There were 399 ( 37. 54% ) overweight, 36 ( 3. 39% ) obesity, 130 ( 12. 23% ) increased NC, and 354 (33.30%)increased WC in 1063 aircrew members (OSAHS group ＞ snore group ＞ normal group; P＜O. 05). The mean value of BMI, NC and WC in the three groups were dittos. Multiple logistic regression analysis showed that overweight, obesity and increased WC were significantly associated with snoring (P ＜0.05) and snoring enlarged NC was significantly correlated with OSAHS (P＜ 0.05). Conclusion Increased BMI, NC and WC may be risk factors of OSAHS among aircrew. Effective prevention and treatment of OSAHS should be needed.
