This paper introduces a statistics method for the segmentation evaluation for the head MRI. A new evaluation scheme proposed, the evaluation result is analyzed objectively by the statistic method. Genetic neural network algorithm proves with a stronger antinoise ability than other ones. The statistic method is helpful for evaluating the segmentation objectively.

The pathogenesis of diabetic retinopathy (DR) is more complex. For the upstream of traditional pathogenesis, to looking for unifying mechanism theory which proposed in foundation of common promoters and the latest view of DR may be the result of chronic inflammation. Both of them provide the basic and clinical theraby of DR with new direction. Therefore, there are many related issuess till needs to intensive study.

Objective To analyze the surgical management and prognosis of hilar cholangiocarcinoma(HCC).MethodClinical data of 72 patients with HCC were retrospectively analyzed.Results There was a significant difference in the 3- and 5- year survival rates and median survivals among the groups treated with different surgical methods(x2 =28.1,P＜ 0.01 ).Univariate analyses conducted for the 16 factors which might affect prognosis showed the surgical method,lymphatic metastasis,positive margin,as well as the type of pathology and staging were of statistically significant prognostic value (P＜0.05).On a multivariate analysis using the Cox proportional hazards model,surgical management,lymphatic metastasis and the type of pathology and staging were independent prognostic factors (regression coefficient 1.4157,1.1072,1.6435).ConclusionRadical excision is an important prognostic factor for HCCa and extended resection improved the long-term survival rates of radical surgery.

Fine-needle aspiration biopsy is the mainstay of preoperative diagnosis of thyroid cancer which is the most common type of endocrine malignancy.However,some aspirates yield indeterminate cytology and there is no clear recommendation for the management on these situations.The use of emerging molecular markers such as BRAF、RET、PAX8/PPARγ will likely improve the diagnosis of malignancy in thyroid nodules and facilitate more individualized therapeutic options and postoperative management.Some markers have been extensively characterized and introduced into clinical practice.

Objective To determine the best processing technology of Prunus mume carbon.Methods L_9(3~4) Orthogonal design was used with three factors of processing temperature,stir-fry frequency,and time.The indicators of processing technology of P.mume carbon were the blood coagulation time,hemostasis time of mice,the contents of the water-solubility,the extract of alcohol-solubility,combined with product characters,yielding rate,and diameter size to optimize the processing technology of P.mume carbon.Results The optimized processing technology was as following:The processing temperature was 235℃,the stir-fry frequency was 80 times/min,and the processing time was 7.5 min.Conclusion The optimized processing technology is stable and operable,and meets the need to enhance the effect of blood coagulation,the carbonizing process of"the superficial burnt black,the internal burnt orange".

Objective: To examine the relations among objective peer support, perceived peer support, perceived parent support, importance ratings of peer / parent support, and self- worth in adolescents. At the same time, peer acceptance of adolescents was examined. Methods: Sociometric techniques and self- report instrument were applied collectively to a sample of 285 adolescents. Results: ①Sociometric techniques show that adolescents can be divided into popular adoles- cents, rejected adolescents, controversial adolescents, and neglected adolescents; ②There are significant positive correla- tions between objective peer support and perceived peer support, between perceived peer / parent support and self- worth, but there is no significant correlation between objective peer support and self- worth; ③Importance ratings of peer / parent support can serve as a moderator between perceived peer / parent support and self- worth for the middle school students aged 15. Conclusion: Perceived peer / parent support can predict self- worth of adolescents; Importance ratings of peer / parent support can moderate perceived peer / parent support and self- worth for the middle school students aged 15.

Objective: To investigate the relationship of the terminal position of the muscular contraction path and centric relation position with different vertical dimension.Methods: The terminal position of the muscular contraction path and centric relation position with different vertical dimension were recorded for ten edentulous patients with gothic arch.Results: The mesial distance between the terminal position of the muscular contraction path and centric relation position increased with the vertical dimension.The lateral dimension between the terminal position of the muscular contraction path and centric relation position,the distribution of the terminal position of the muscular contraction path are not correlated to the vertical dimension.The center of the terminal position of the muscular contraction path is 1-4 mm ahead of the centric relation position and(0.42?0.47) mm lateral to the centric relation position.The distribution of the terminal position of the muscular contraction path is(1.36?0.58) mm in the mesial-distal direction,(1.56?0.62) mm in the lateral direction.Conclusion: With the increase of the vertical dimension,the mesial distance between the terminal position of the muscular contraction path and centric relation position increased.

In order to improve the knowledge of clinicians in hypoxia of COPD during the night,the physiological changes of arterial oxygen and carbon dioxide during sleep in healthy population were investigated at first,and the features and state of oxygen deficiency during sleep in patients with COPD were analyzed.Furthermore,the possible mechanism,effect,predictor,diagnosis and therapy were explored.

[Objective] To observe the therapeutic effects of acupuncture and manipulation on acute lumbar sprain.[Methods] 144 patients were randomly divided into 3 groups: the first treatment group treated with acupuncture at YAOTON point,the second group with manipulation and the third group with two methods above.The effects were assessed after 1 w and 1 m.[Results]After 1 w,there was significant difference in 3 groups: the therapeutic effects in the band group was better than other 2 groups,but no difference in other 2 groups.[Conclusions] Both acupuncture at YAOTONG point and manipulation are good methods for acute lumbar sprain.
