BACKGROUNDOlder patients with malignant spinal tumors are difficult to treat because they have many co-morbidities including osteoporosis. The purpose of this research is to discuss the technique and clinical outcome of bone cement enhanced pedicle screw fixation combined with vertebroplasty (the Sandwich Procedure) for elderly patients with severe osteoporosis and malignant spinal tumors.

METHODSThis study includes 28 consecutive elderly patients with malignant thoracic or lumbar spinal tumors. There were nine patients with myelomas, and 19 patients with metastatic bone tumors. The Sandwich Procedure began with curettage of the tumor and a vertebroplasty with bone cement (polymethyl methacrylate, PMMA), followed by PMMA enhanced pedicle screw fixation. Patients were evaluated with the visual analogue scale (VAS), oswestry disability index (ODI), American Spinal Cord Injury Association (ASIA) neurological function classification, and the radiographic degree of kyphosis (Cobb angle). Data were analyzed using paired t-test to compare the pre- and post-operative values. The complications, local recurrences, and the survival status were also recorded.

RESULTSThere was no operative mortality, and the mean operative time was 210 minutes (range 150 - 250 minutes). The average blood loss was 1550 ml (range 650 - 3300 ml). The average amount of cement for vertebroplasty was 3.6 ml (range 3 -5 ml). The VAS, ODI, and ASIA scores were significantly improved after surgery (P < 0.05). However, we found no differences between the pre and post-operative Cobb angles. The shortest survival time was 3 months, and we found no evidence of local recurrence in this group of patients.

CONCLUSIONThe Sandwich Procedure is a safe operation and provides symptomatic relief in these difficult patients, permitting further treatment with chemotherapy or radiotherapy.

OBJECTIVETo investigate the characteristics of human caliciviruses (HuCV) diarrhea among infants and young children with acute diarrhea in Lanzhou, Gansu Province, China by using molecular epidemiologic techniques.

METHODSStool specimens were collected from both outpatients and inpatients with acute diarrhea in Lanzhou. Enzyme-linked immunosorbant assay (ELISA) was used to detect rotavirus antigen (RVA). Reverse transcription-polymerase chain reactions (RT-PCR) were used to detect HuCV in stool specimens of RV ELISA (-).

RESULTSOf the stool specimens collected from 515 cases in Lanzhou from December 2001 to June 2004, 264 were RVA ELISA (+) and 251 were RVA ELISA (-). Among all cases who were RVA ELISA (-), 25 (9.96%) were found positive for HuCV. HuCV was detected in 12 of 133 cases (9.02%) from December 2001 to November 2002, no genotyping was performed for these cases. From July 2003 to June 2004 13 of 118 cases (11.02%) were found positive for HuCV, of whom 11 cases had Norwalk-like virus GII (NLV GII) infection and 2 cases had Sapporo-like virus infection (one case had combined infection with astrovirus) and no NLV GI was found. HuCV infection mainly occurred in children under 2 years of age and no seasonal cluster was found.

CONCLUSIONHuCV is one of the major etiological agents of viral diarrhea among infants and young children in Lanzhou. NLV GII maybe the predominant genotype.

Objective To explore the common causes of epilepsy and the etiologic characteristics in different age groups of patients with epilepsy.Methods A retrospective survey was made in 5572 epilepsy patients in Epileptic Center of Guangdong 999 Brain Hospital from January 2003 to December 2009.According to the diagnostic criteria published in 2005 from ILAE,all the diagnoses of 5572 cases were made by epileptic specialists.Based on history,cranial MRI or CT and pathologic data,causes of epilepsy were classified into idiopathic,symptomatic and cryptogenic epilepsy.The cases of symptomatic epilepsy were further arranged into different categories in different age grades,such as head trauma,perinatal injuries,infection in central nervous system, cerebral vascular disease, brain tumor, disorders of cortical development,neurocutaneous syndrome and others.The cases with febrile seizures and family history were collected,and positive ratio of febrile seizures and family history were contrasted in different categories of cases by Kruskal-Wallis test ( nonparametric test ).Results In 5572 cases,66 were idiopathic,2834 symptomatic,2672 cryptogenic,and the ratio of these causes was 1％,51％,48％ respectively.Among 2834 cases of symptomatic epilepsy,822 were head trauma,497 were perinatal injuries,360 were infection in central nervous system,249 were brain tumor,150 were cerebral vascular disease,135 were disorders of cortical development,62 were neurocutaneous syndrome and 559 were others. In brief,head trauma,perinatal injuries,infection in central nervous system,brain tumor and cerebral vascular disease were top 5 causes of symptomatic epilepsy. Hippocampal sclerosis was found in 744 cases in those of eryptogenic epilepsy.The importance of febrile seizures( idiopathic:15.2％ ( 10/66 ),symptomatic:6.5％ ( 185/2834 ),cryptogenic:9.4％ ( 250/2672 ) ; x2 =181.393,P =0.000 ) and family history ( idiopathic:83.3％ ( 55/66 ),symptomatic:1.1％ (31/2834),cryptogenic:0.4％ (12/2672) ; x2 =68.354,P =0.000) was statistically different in different causes of epilepsy.Febrile seizures was the most frequent in cases with hippocampal sclerosis than those with other causes,and family history was the most frequent in neurocutaneous syndrome in symptomatic cases.Perinatal injurics was thc first causc in cases of infancy and childhood,head trauma was the top one in those of juvenile and adulthood,and cerebral vascular disease was the main cause in senile cases. Conclusions In the whole epileptic cases of 5572, 1％ was idiopathic,51％ was symptomatic,and 48％ cryptogenic. The main causes of them were head trauma,perinatal injuries,infection in central nervous system,brain tumor,and cerebral vascular disease.

Objective To investigative CT findings of gastrointestinal neurilemmoma,and to improve the recognition and diagnosis ability of the disesase.Methods Twelve cases of gastrointestinal neurilemmoma proven surgically and pathologically were included.The unenhanced CT and double phase enhanced CT were performed in all patients.The clinical feature and CT findings with regard to the location, size,contour,margin,growth type,contrast enhancement pattern,contrast enhanced degree,presence or absence of ulcer were retrospectively reviewed by two experienced radiologists.Results On unenhaneed CT, all the patients present masses with homogeneous attenuation in the wall of gastrointestinal tract,compared with muscle.Three of the gastric neurilemmoma showed endoluminal growth pattern,and 6 had a predominantly exophytic growth pattern,the tumor had both endoluminal and exophytic growth pattern in 3 cases.The tumors were round or oval with distinct margin in 10 of 12 gastrointestinal neurilemmoma,and lobulated with indistinct margin in 2 cases.Three of the gastric neurilemmoma had ulceration.On contrast- enhanced CT,all the tumors showed homogeneously solid mass.No obvious enhancement on the arterial phase showed moderate enhancement on portal vein phase in 10 cases,2 of gastrointestinal neurilemmoma which manifested mild enhancement on the arterial phase showed obvious enhancement on portal vein phase. Conclusion CT findings of most gastrointestinal neurilemmoma have characterstic,which appeared as round or oval,distinct margin,and homogeneously solid tumors,slow but fairly uniform and moderate enhancement throughout the mass.

BACKGROUND: Many studies have showed that apoptosis of endothelial cells plays a curial role in the progress of sepsis. But the role of simvastatin in apoptosis of endothelial cells induced by sepsis is not clear. The present study aimed to investigate the role of simvastatin in apoptosis of endothelial cells induced by sepsis and its mechanism. METHODS: Human umbilical vein endothelial cells (HUVECs) were randomly divided into three groups: control group, sepsis serum intervention group (sepsis group) and simvastatin+sepsis serum intervention group (simvastatin group). After 24-hour incubation with corresponding culture medium, the relative growth rate of HUVECS in different groups was detected by MTT assay; the apoptosis of HUVECs was detected by Hoechst33258 assay and flow cytometry; and the expression of the Bcl-2 and Bax genes of HUVECs was detected by PCR. RESULTS: Compared with the sepsis group, HUVECs in the simvastatin group had a higher relative growth rate. Apoptotic HUVECs decreased significantly in the simvastatin group in comparison with the sepsis group. Expression of the Bcl-2 gene in HUVECs decreased obviously, but the expression of the Bax gene increased obviously after 24-hour incubation with sepsis serum;however, the expression of the Bcl-2 and Bax genes was just the opposite in the simvastatin group. CONCLUSIONS: Our study suggests that simvastatin can inhibit apoptosis of endothelial cells induced by sepsis through upregulating the expression of Bcl-2 and downregulating Bax. It may be one of the mechanisms for simvastatin to treat sepsis.

Objective To evaluate the clinical application and security of percutaneous endoscopic gastrostomy (PEG) with the Introducer method using ultrathin gastroseopy in dysphagia patients. Methods Clinical data of 22 cases dysphagia patients implemented with PEG with the Introducer method using ultrathin gastroseopy or conventional gastroseopy were retrospectively analyzed, the clinical effect and the complication were observed. Results 22 patients underwent PEG with the Introducer method using conventional gastroscopy (6 cases) or ultrathin gastroscopy (16 cases). Among the 16 patients underwent PEG using ultrathin gastroseopy by transnasal or peroral approach, 2 cases with trimus by received radiotherapy for nasopharyngeal cancer and 14 cases with pharyngeal or esophagus narrowing, could not completed PEG by conventional gastroscopy. The average procedure time of PEG was (12.2 ± 2.9) min in conventional gastroscopy group and (11.8 ± 3.2) min in control group. No complications were observed in these patients, but the patients in ultrathin gastroseopy group reported less discomfort associated with the procedure. 17 patients with advanced nasopharyngeal carcinoma and esophagus cancer who received PEG could completely finished 6 cycles of concurrent chemoradiotherapy. Paired-sample t test of nutrition indicators (hemoglobin, albumin and RBC) before and after the treatment showed significant difference (P < 0.05). Conclusion PEG with the introducer method using ultrathin gastroseopy is a safe and effective method of enteral nutrition, Ultrathin gastroscopy reduces the discomfort of the procedure, especially in patients with serious trimus and pharyngeal or esophagus narrowing. For patients with advanced nasopharyngeal carcinoma, preventative PEG improved the tolerance of chemoradiotherapy,reduce the incidence of adverse events.

OBJECTIVETo evaluate the effects on cardiac remodeling post transcatheter closure by Amplatzer septal occluder selected by oval circumference formula in patients with atrial septal defect (ASD).

METHODSA total of 146 patients with ASD (68 males,mean 33.5 years) treated by transcatheter closure with the Amplatzer occluder were enrolled in this study. The diameter of defects was corrected with the oval circumference formula (group A, 73 cases) or by echocardiography (group B, 73 cases). Cardiac remodeling was assessed by transthoracic echocardiography (TTE) before the procedure, 3 days, 3 months and 6 months after ASD closure.

RESULTSThe mean ASD diameter was similar between the two groups [(20.16 +/- 4.98) mm vs. (21.36 +/- 5.69) mm, P > 0.05] and the mean diameter of the selected occluder of group A was significantly smaller than that in group B [(21.95 +/- 6.78) mm vs. (25.85 +/- 6.75) mm, P < 0.05]. Procedural success rate was identical between the two groups (97.3%) and the defects were completely occluded and there was no residual shunt during the 6 months follow up period, there were also no complications during and after the procedure. The lateral diameter of right atrial (RALD), the diastolic diameter of right ventricle (RVDD), RALD/LALD, RVDD/LVDD and pulmonary diameter (PD) were significantly decreased while the lateral diameter of left atrial (LALD) and left ventricle (LVDD) were significantly increased post ASD closure in both groups. At 6 months follow up, RALD decreased by (18.63 +/- 10.59)% in group A versus (10.14 +/- 6.59)% in group B, LALD increased by (13.42 +/- 8.38)% in group A versus (9.28 +/- 4.95)% in group B and RALD/LALD ratio decreased by (26.35 +/- 11.24)% in group A versus (13.98 +/- 8.96)% in groups B (all P < 0.05).

CONCLUSIONASD occluder selection based on the oval circumferen ce formula is superior to that made by echocardiography in terms of more favorable cardiac remodeling post ASD closure.
