Objective To investigate the relationship between primary hepatocellular carcinoma (HCC) with multiple nodules and short-term recurrence after radical resection.Methods We retrospectively analyzed the clinical data and follow-up of 692 consecutive HCC patients who underwent curative resection at the Affiliated Hospital of Qingdao University from January 2000 to December 2011.The diagnosis of multiple nodules was based on preoperative imaging data and observations in operation.Results Of 692 HCC patients, 126 patients had multiple nodules (18.2％, the MN group) and 566 patients had a single nodule (71.8％, the SN group).The 1-, 2-, 5-, and 10-year overall survival (OS) rates were 86.5％,72.2％, 38.1％, and 23.2％ for the MN group, and 93.8％, 82.7％, 58.2％, and 35.7％ for the SN group, respectively (P ＜ 0.05).The 1-, 2-, 5-, and 10-year disease-free survival (DFS) rates were 68.6％, 46.8％, 27.2％, and 19.8％ for the MN group, and 80.2％, 62.1％, 42.0％, and 34.6％ for the SN group, respectively (P ＜ 0.05).Cox regression model analysis showed a maximum nodule diameter of ＞ 5 cm was an independent risk factor of short-term recurrence in the MN group.Conclusions The prognosis of HCC patients with multiple nodules after radical resection was poorer and the short-term recurrence rate was significantly higher than those patients with a single-nodule.A maximum nodal diameter of ＞ 5 cm was an independent risk factor of short-term recurrence for patients with multiple nodules after radical resection.Therefore, patients with multiple nodules, especially ＞ 5 cm, should be followed up closely and they are good candidates for a multiple disciplinary team (MDT) treatment.

Objective:Cluster and discriminant analysis of the morphological characters of Angle's Class Ⅱ malocclusion was performed using Procrusts standardization.The classification of craniofacial morphology with the help of morphometry and multivariate statistics was also discussed.Methods: A total of 894 class Ⅱ patients were collected from the orthodontic department,Peking University School and Hospital of Stomatology during 1997-2000.Using Procrusts standardization and cluster analysis,the samples were divided into different groups,discrimination equations were then established.Results: The samples were divided into 11 subdivisions by Procrusts superimposition and cluster analysis.Three discrimination equations were established.The accuracy rate of cross-validated grouped cases was 80.17%.Conclusion: Procrusts standardization had certain advantages in morphological classification;cluster analysis could be used in classification of Angle class Ⅱ malocclusion;For different types,the differentiate rate was not the same;the discrimination equations was the foundation for future research.

OBJECTIVE To investigation central venous catheter-related infections(CRI) in critical patients. METHODS Fifty-nine cases from Jul 2006 to Jun 2007 in intensive care unit (ICU) of our hospital were analysed retrospectively. RESULTS Among 59 cases, 27 cases were with positive results of fungi (51.85%) and bacteria(48.15%) in which G+(25.93%) and G-(22.22%). CONCLUSIONS CRI is related to the indwelling time, fungi are the major pathogens. It is important to prevent CRI through careful nursing. We must pull out the catheters if recessary and antibiotics should be used reasonablly.

Objective To report the results of the surgical treatment of cervical spondylotic myelopathy(CSM) secondary to athetoid cerebral palsy and clarify the characteristics and the principle of treatment of the disease. Methods The age of the patient, segments of vertabrae involved and operated upon, results and complications of 32 cases with CSM secondary to athetoid cerebral palsy were statistically analyzed and compared with 93 patients who had isolate CSM operatively treated at the same time. Results 1)The average age of the patients in the group of CSM secondary to athetoid cerebral palsy was 37.94 years,and in the group of isolate CSM was 52.48 years, with significant statistic difference(P

TBL (Team-based learning) model is a new teaching method.By evaluating the effect of TBL model in theory teaching on Chinese orthodontic postgraduate program in the department of Orthodontics,Guanghua School of Stomatology,Sun Yat-sen University,and comparing the traditional teaching model which centered on teachers,we have probed into the application experience of TBL teaching method in curriculum setting of preclinical theoretic learning in orthodontics postgraduate education.The result shows TBL has significantly enhanced students' enthusiasm for learning,sense of collaboration,and has improved the quality of education.TBL method is better,even though there is something that needs to be improved.

Objective To study the relationship between essential hypertension(EH)with serum homocysteine(HCY),uroten-sinⅡ(UⅡ),angiotensin converting enzyme(ACE)and N-terminal pro-brain natriuretic peptide(NT-proBNP).Methods By collec-ting the clinical cases,UⅡwas determined by ELISA and HCY,ACE and NT-proBNP were simultaneously detected by ELISA.The detection results were analyzed and compared between the patients with essential hypertension(EH group)and the healthy con-trols.Results The levels of serum HCY,UⅡ,ACE and NT-proBNP in the EH group were significantly increased compared with the healthy control group;the area under curve (AUC)of serum HCY,UⅡ,ACE and NT-proBNP in the ROC curve in the EH group were 0.93,0.765,0.792 and 0.972 respectively,which showed clinical diagnostic significance.Conclusion The levels of HCY,UⅡ,ACE and NT-proBNP are highly expressed in EH and have significant differences compared with the healthy popula-tion,which has the diagnostic value to EH.
