Analyses of correlations between the measured values of the foramen ovale of dry skulls and those of roentgenographic skull base films of the corresponding specimens were carried out in 99 male adult skulls collected from the vicinity of Shanghai. The items in our studies included the length and width of the foramen ovale, the angle between the longitudinal diameter and the sagittal plane running through the intermaxillary suture, the distance from the foramen ovale to the foramen spinosum and that to the sagittal plane, and the distance from the foramen spinosum to the sagittal plane.Significant correlations(P

We have modified the horizontal glotiectomy designed by Claearo. 18 patients suffering from the cancer of bilateral vocal cords were treated by our modified surgical procedure in 1983 to l990.Of 18 patients, 17 had glottic cancer: 10 in T1bN0 M0, 4 in T2N()M0 and 3 in T3N0M0; patient had T3N0M0 of infra-glottic cancer .The function of phonation, deglutition and respiration of the larynx restored quickly after operation. The voice is satisfactory. The nasogastric tube was left ir place for several days after operation. The cannula were removed in all patients.One patient died of non-specific encephalitis in 4th year postoperatively. Other 17 patients are still alive after operation. 1 patient has been followed up for 7 years, 4 for 5 years, 2 for 4 years, 3 for 3 years, 5 for 2 years, 3 for less than 2 years. They were doing well after operation and now have engaged themselves in physical labour or professional work

BACKGROUND:In the treatment of teeth later fixed appliance, whether the expansion effect can be maintained? Whether the expansion in the process of mandibular rotation could be improved? Whether the high angle cases are suitable for rapid palatal expansion? OBJECTIVE:To sum the effect of rapid maxil ary expansion combined with fixed orthodontic technique on the occlusion craniofacial three-dimensional direction, hard and soft tissues and temporomandibular joint, as wel as its long-term stability. METHODS:The CNKI database, PubMed database and Wanfang database were searched for the academic journals and literatures on rapid maxil ary expansion combined with fixed appliance with the key words of“maxil ary expansion, fixed appliance, high angle, stable”. The analysis function of database was used. RESULTS AND CONCLUSION:Rapid maxil ary expansion can effectively obtain arch expansion, increase the arch width, and provide space of align teeth required. Fixed appliance can effectively control the tooth movement in three-dimensional space, precisely adjust the teeth, and make the tooth rows into the ideal arch form. Combination of these two kinds of appliances can obtain the complementary efficiency advantages of the appliances, and shorten the treatment course. Expansion can cause mandibular clockwise rotation and mandibular plane angle increasing, while with the application of upper and lower fixed appliance, the occluding relation between maxil a and mandible can be adjusted more precisely in order to make the mandibular first molar move to the maxil ary molar buccal, establish good occlusal relationship, so that decrease the mandibular plane angle. So the rapid maxil ary expansion combined with fixed orthodontic can be used appropriately in the treatment of the patients with high angle intraversion.

Serum concentrations of sialic acid, fucose, prealbumin(PA ), ?1-antitrypsin (?1-AT), ?1-acid glycoproteins(?1-AGP), haptoglobin (HP) and transferrin (TF) were measured in 94 nasopharyngeal carcinoma and 65 cancer of larynx. Statistical evalution was made with stepwise discriminant analysis, and the discriminant functions were obtained. The effectiveness of allocation were examined on every one of all patients in the original data, Our results suggested, with the discriminant function equation consisting of serum PA, ?1-AT, ?1-AGP, HP and TF concentrations we could best separate the patients sufferng from nasopharyngeal or laryngeal carcinoma from the normal; the effective rate of discriminant was 87.36% and 88% for nasopharyngeal carcinoma from normal and laryngeal carcin-oma from normal respectively. However using discriminant function equation,composed of serum sialic acid, PA and ?1-AT, we could also discriminate nasopharyngeal or laryngeal carcinoma with recurrence from the one with non-recurrence, the effective rate of discriminant was 93.1% and 80% for nasopharyngeal carcinoma and cancer of larynx respectively

Analysis of patient satisfaction , as the supplement and improvement of the traditional medical quality assessment , has great significance for improving the quality of medical services , reducing the medical disputes and building a harmonious doctor -patient relationship .Based on the connotation of patient satisfaction , the patient satisfaction theory at home and abroad were introduced , providing a guide meaning for establishing a rational evalua-tion system and scientifically managing hospital service .

The policy of“licensed doctors'multi-site clinical practice” aims to provide patients with a better access to quali-ty medical and health resources.Patient's understanding and support indicates the executive condition of the implementation of the pol-icy and it can also promote the implementation of the policy to a certain extant .In this study , the questionnaire survey and statistical tools were used to investigate the differences in their attitudes to the policy .

Objective To label rat bone marrow mesenchymal stem cells with superparamagnetic iron oxide (SPIO) and to explore the tropism of BMSCs for hepatocellular carcinoma cells after transplantation in vivo. Methods BMSCs from bone marrow of Sprague-Dawly (SD) rats were cultured isolated and purified, Labeled BMSCs was achieved using Feridex. Twenty-four hepatocellular carcinoma models of SD rats were induced two weeks before tmnsplantation. The models were divided into three groups in random: the labeled BMSCs and unlabeled BMSCs were transplanted respectively into the rat's livers of experimental group (n = 12) and control group A(n =6) via spleens, and no transplant was done for control group B (n =6). MR imaging was performed to monitor the transplanted cells after 1,3,7,14 d using 1.5 T MR system. Signal intensity ratio (SI/SI*) between tumor and hepatic tissue on T_2 * WI were measured and compared by one-factor analysis of variance. After MR imaging, Prussian blue staining was performed. MR imaging findings were compared with histological sections. Results Prussian blue staining confirmed the labeling efficiency of BMSCs was above 90%. SI/SI* of experimental group before and 1, 3, 7, 14 d after transplantation were 3.18±0.21,1.98±0.20,2.38±0.28,2.70±0.25 and 3.16±0.24 respectively. Following transplantation of BMSCs, signal intensity decrease was found in hepatocellular carcinoma of experimental group(F =56.65,P <0.05) and low signal change decreased gradually and disappeared at two weeks after transplantation, while no remarkable low signal change was seen in the control group by T_2 * WI (P > 0.05). A large number of Prussian blue staining positive cells were found in hepatocellular carcinoma in experimental group. Histological section with Prussian blue staining had a good correlation with the signal intensity changes on MR images at different time. Conclusion BMSCs display significant tropism to hepatocellular carcinoma and may be an ideal gene therapy vehicle against hepatocellular carcinoma.
