Objective To investigate the safety and long-term therapeutic results of anatomical hepatectomy for hepatocellular carcinoma (HCC).Methods 90 patients underwent anatomical hepatectomy from January,2003 to January,2010.The tumor size was ≤5 cm in 38 patients,and ＞5 cm in 52 patients.The tumor number was a single lesion in 58 patients,and multiple lesions in 32 patients.Cirrhosis was present in 46 patients (55.42％); cancer embolus was present in 34 patients (37.78％).There were 64 patients in Child-Pugh A and 26 patients in B.The operating time,blood loss and blood transfusion were recorded and analyzed.Complications and liver function were monitored after surgery.The Kaplan-Meier method was used to calculate the survival rates.Log-rank test was used to analyze factors associating with postoperative recurrence.Independent factors influencing tumor-free survival and overall survival were analyzed by Cox-model logistic regression.Result There was no perioperative death.The incidence of complications was 31.1％ (28/90).The recurrence rate was 51.1％ (46/90).The 1-,3-,5 year tumor-free survivals were 92.2％,67.3％ and 49.7％％00,respectively.Positive resection margin and satellite nodule were independent factors for recurrence (RR19.22,95 ％ confidence interval 5.85～63.17).The 1-,3-,5-year overall survivals were 94.4％,80.0％ and 60.0％,respectively.Positive resection margin and TNM were independent factors for overall survival (RR 2.013,95％ confidence interval 1.28～3.17).Conclusions Anatomical hepatectomy was a safe and efficacious procedure to treat HCC.Positive resection margin and TNM were independent factors associated with overall survival.Anatomical hepatectomy had the advantages in ensuring a lower rate of negative resection margin.

The clinical value of whole body positron emission tomography/computed tomography (PET/CT) as an imaging tool in diagnosis of ophthalmic tumors was investigated.The retrospective observational case series were performed on the patients with suspected ophthalmic tumors who underwent whole body PET/CT.The golden standard of diagnosis was the final pathological diagnosis or the results of long-term follow-up for patients without surgery/ biopsy.PET/CT findings were compared with the golden standard.The sensitivity,specificity,accuracy and positive likelihood ratio of PET/CT in the detection of ophthalmic tumors were calculated.The clinical application of PET/CT in different types of ophthalmic tumors was evaluated.The results showed that 30 patients (18 males and 12 females) with a mean age of 43.0 years (range 4-63 years) were collected.The mean sizes of orbital tumors and intraocular tumors were 26.8 mm×17.8 mm and 11.2 mm×6.1 mm,respectively.The overall sensitivity,specificity,accuracy and positive likelihood ratio of whole body PET/CT in ophthalmic tumors were 76.5％,71.4％,75.0％ and 2.67,and were 62.5％,100％ and 70.0％ in intraocular tumors,and those were 100％,60.0％ and 84.6％ in orbital tumors,respectively.PET/CT findings were applied to help make appropriate treatment options in 27 out of 30 patients (90.0％),and 12 (40.0％) patients changed the treatment strategy.False negative results in 4 cases and false positive results in 2 cases were observed in this series.It was suggested that PET/CT was an effective imaging modality in detecting,diagnosing and developing therapeutic schedule for patients with ophthalmic tumors.It was more sensitive and accurate for detecting orbital tumors than for detecting intraocular tumors.

Objective To explore the effect of community comprehensive intervention on stroke-prevention-related knowledge, belief and behavior of hypertensive patients. Methods The community-based comprehensive interventions were done to 77 hypertensive patients, with the measures including archives establishment, hypertension-phased management, regular follow-up and multi-mode health education. The stroke-prevention-related knowledge, belief and behavior of them were assessed by the stroke-preventing knowledge questionnaire (SPKQ), champion′s health belief model scale (CHBMS) and (stroke-prevention behavior questionnaire,SPBQ) before and after the intervention. Results Their knowledge on daily-life and pre-stroke symptoms and part of their behaviors (health duty, physical exercises and stress management after the intervention were superior, as compared to the pre-intervention (P<0.05). There were no significant differences in other stroke-related knowledge and behaviors and health belief in comparison of the pre-and post-intervention (P>0.05). Conclusion The community-based intervention can improve parts of stroke prevention knowledge and health behavior among hypertensive patients. The intervention needs to be modified based on ecological models of health promotion and health belief model.

AlM: To measure ocular biometric values with the degree of axial myopia and determine the relationship between the differences using the Lenstar 900.
METHODS:Totally 413 myopes (826 eyes) were enrolled in this study and were divided into 3 groups: low myopia (myopia <3. 00 diopters, 104 eyes), moderate myopia ( myopia =3. 00-6. 00 diopters, 500 eyes) and high myopia ( myopia > 6. 00 diopters, 222 eyes ). Central corneal thickness ( CCT ) , aqueous depth ( AD ) , lens thickness (LT), axial length (AL) were measured by Lenstar 900. The parameters were tested using analysis of variance and the relations among SE, AL, LT were analyzed.
RESULTS: There were significant difference both in AL (F=206.16, P<0.01) and AD (F=4.764, P<0.05) and no significant difference both in CCT and LT between these myopia groups. With analysis of Person, the Spherical equivalent ( SE) shows a significantly positive correlation with AL (r=0. 662, P<0. 01) and AD (r=0. 095, P<0. 05), no correlation with CCT and LT. AL shows a significantly positive correlation with AD (r=0. 347, P<0. 01) and CCT (r=0.126, P<0.01), negative correlation with LT (r=-0.265, P<0. 01). LT shows a significantly negative correlation with AD (r=-0. 496, P<0. 01).
CONCLUSlON: Along with the diopters increasing in myopia, the axial length and aqueous depth continue to increase. Spherical equivalent ( SE) shows a significantly positive correlation with AD. AL shows positive correlation with SE, AD and CCT and negative correlation with LT. LT shows a significantly negative correlation with AD.

Objective To investigate the diagnostic value of EUS with miniprobe on upper gastrointestinal tract mesenchymal tumor(GIMT).Methods The EUS features of 38 patients with GIMT who underwent EUS with miniprobe were studied retrospectively,and the results were compared with the postoperative pathological findings.Results Among 38 GIMT cases detected by EUS,there were 25 cases of gastrointestinal stromal tumor,11 cases of leiomyoma,and 2 cases of leiomyosarcoma.Postoperative histopathological and immunohistochemical examinations confirmed 28 cases of stromal tumor.In which 6 cases were high-risk GIST,8 cases were leiomyoma,1 case was leiomyosarcoma,and 1 case was neurofibroma.The accuracy of diagnosis with EUS was 89%.Conclusion EUS is an accurate method in diagnosis of submucosal tumors,which can make better differentiation diagnosis between GIMT and other submucosal tumors.

0.05).The Cormack and Lehane laryngeal exposure grades obtained by the Macintosh laryngoscope with and without ELM were significantly different(Z=3.55 P0.05).Of all 33 pediatric patients,successful orotracheal intubation using the GSLV was completed by one attempt in 31 patients and by 2 attempts in 2 cases.The time required to achieve successful tracheal intubation was 20-51(30.0? 7.9) s.Conclusions GSLV is as useful as Macintosh laryngoscope for laryngeal exposure and orotracheal intubation in children.When the orotracheal intubation is done using the GSLV in children,the distal end of a styletted endotracheal tube should be bent anteriorly to an angle of 70-80 degrees and ELM is routinely used.

ObjectiveTo investigate the effects of postconditioning with electric vagal stimulation on myocardial ischemia-reperfusion (I/R) injury in rats.MethodsSixty male SD rats weighing 250-350 g were randomly divided into 3 groups (n ＝ 20 each):group sham operation (group S); group myocardial I/R (group I/R) and group electric vagal stimulation postconditioning (group POES).Myocardial I/R was induced by occlusion of left anterior descending branch of coronary artery for 30 min followed by 120 min reperfusion in groups I/R and POES.In group POES right cervical vagus nerve trunk was stimulated for 30 min with continuous electric rectangular pulses (2 ms,10 Hz) starting from 15 min of myocardial ischemia.The voltage of the pulses was adjusted to decrease HR by 10％ of the baseline HR before stimulation.MAP,HR and RPP (MAP× HR) were recorded before (baseline) and at 1 and 10 min of ischemia and 30,60 and 120 min of reperfusion.Arterial blood samples were collected from 10 rats in each group at 120 min of reperfusion for determination of serum concentrations of cTnI,CK-MB,TNF-a,high mobility group box 1 protein (HMGB1),ICAM-1,IL-1,IL-6 and IL-10 (by ELISA).The animals were then sacrificed and myocardial infarct size was measured by Evans blue and TTC staining.Another 10 rats were sacrificed at 120 min of reperfusion for determination of myocardial contents of TNF-α,HMGB1,ICAM-1,IL-1,IL-6 and IL-10 (by ELISA).ResultsI/R induced myocardial infarct,significantly increased serum concentrations of cTnI,CK-MB,TNF-α,HMGB1,ICAM-1,IL-1 and IL-6 and significantly increased myocardial contents of TNF-α,HMGB1,ICAM-1,IL-1,IL-6 and IL-10 in both ischemic and non-ischemic regions in group I/R as compared with group S.Electric vagal stimulation significantly decreased myocardial infarct size and serum concentrations of cTnI,CK-MB,TNF-α,HMGB1,1CAM-1,IL-1 and IL-6 in group POES compared with group I/R.Myocardial contents of TNF-α,HMGB1,ICAM-1,IL-1 and IL-6 were significantly decreased while myocardial IL-10 content was increased in both ischemic and non-isehemic regions in groups POES compared with group I/R.ConclusionPostconditioning with electric vagal stimulation can attenuate myocardial I/R injury by inhibiting inflammatory response in rats.

Based on the capacitance coupling principle, we studied a capacitive way of non-contact electrocardiogram (EGG) monitoring, making it possible to obtain ECG on the condition that a patient is habilimented. Conductive fabric with a good electrical conductivity was used as electrodes. The electrodes fixed on a bed sheet is presented in this paper. A capacitance comes into being as long as the body gets close to the surface of electrode, sandwiching the cotton cushion, which acts as dielectric. The surface potential generated by heart is coupled to electrodes through the capacitance. After being processed, the signal is suitable for monitoring. The test results show that 93.5% of R wave could be detected for 9 volunteers and ECG with good signal quality could be acquired for 2 burnt patients. Non-contact ECG is harmless to skin, and it has advantages for those patients to whom stickup electrodes are not suitable. On the other hand, it is convenient to use and good for permanent monitoring.

Objective To review and sum up the experience of diagnosis and surgical treatment of cardiac myxoma. Methods 133 patients with cardiac myxoma of different locations from January 1990 to May 2007 admitted in Qilu Hospital of Shandong University and Department of Cardivovascular Affdiafed Zhong shan Hospital of Xiamen Unversity were clearly diagnosed by two dimensional echecardiography. The tumors of 109 patients were located in left atrium ,22 in right atrium and 2 in both cardiac atria. All the patients underwent tumor extirpation under extracor-poreal circulation. Atrioventricular valve plasty was performed when necessary. 11 underwent bicuspid valvuloplasty and 6 underwent tricuspid valvuloplasty at the same time. All the minors were sent to histopathology examination. Re-suits Two patients died of low cardiac output syndrome in early postoperative period. Cerebral embolism happened in 6 cases,left lower extremity embolism and pulmonary embolism in 1 ease respectively. Other patients' symptoms were improved and the physical sign disappeared. All the tumors were demonstrated to be benign cardiac myxoma. Conclusions Most cardiac myxoma is benign but its clinical consequence is severe. So tumor extirpation should be performed as soon as possible and the following-up is important after operation. Prevention of tumor defluvium is im-portant. Two dimensional echocardiography is preferred in the diagnosis of cardiac myxoma.

Objective To investigate the effects of postconditioning with α7 nicotinic acetylcholine receptor (α7nAChR) agonist and ischemia on myocardial ischemia-reperfusion (IR) injury in rats. Methods Fifty adult male SD rats weighing 290-320 g were randomly divided into 5 groups ( n = 10 each): Ⅰ sham operation group, Ⅱ IR group, Ⅲ ischemic postconditioning group, Ⅳ α7nAChR agonist postconditioning group and Ⅴpostconditioning with α7nAChR agonist and ischemia group. Myocardial I/R was induced by ligation of anterior descending branch of left coronary artery for 30 min followed by 1 80 min of reperfusion. In group] the anterior descending branch was only exposed but not ligated. In group Ⅲ the hearts were subjected to 3 episodes of 10 second ischemia at 10 second intervals at the end of 30 min ischemia before 180 min reperfusion, Intraperitoneal PNU282987 2.4 mg/kg was injected at the end of 30 min ischemia before 180 min reperfusion in group Ⅳ and Ⅴ .Blood samples were taken from right internal jugular vein at 180 min of reperfusion. Then the rats were killed and hearts removed to determine the concentrations of serum cardiac troponin-I (cTnI), TNF-α and high-mobility group box 1 (HMGB1) by ELISA. The infarction size was measured by Evans blue and triphenyltetrazolium chloride staining. Results The infarction size was significantly larger in the other groups and concentrations of serum cTrI, TNF-α and HMGB1 were significantly higher in group Ⅱ than in group Ⅰ ( P ＜ 0.05). The infarction size was significantly smaller and concentrations of serum cTnI, TNF-α and HMGBI were significantly lower in group Ⅲ, Ⅴ than in group Ⅱ (P ＜ 0.05). The infarction size was significantly smaller in group Ⅴ and concentrations of serum cTnI, TNF-α and HMGB1 were significantly lower in group Ⅳ and Ⅴ than in group Ⅲ (P ＜0.05). The infarction size was significantly smaller and concentrations of serum cTnI, TNF-α and HMGB1 were significantly lower in group Ⅴ than in group Ⅳ ( P ＜ 0.05 ). Conclusion Postconditioning with α7nAChR agonist and ischemia can reduce myocardial I/R injury and the efficacy is better than that of α7nAChR agonist postconditioning or ischemic postconditioning alone.
