Objective To study the imaging features of the ventricular meningioma, in order to improve the understanding knowledge. Methods Compared with operative and pathological findings,the CT and MRI features of ventricular meningioma were analyzed in 22 patients (8 males and 14 females,range from 17~72 years old with average age 45 years).21 cases were examined by MRI(17 with enhanced scan),11 cases by CT(4 with enhanced scan).Results The ventricular meningioma were mostly fibrous type. Mostly, the locations were in the trigone of the lateral ventricle with regular shape. On imaging, the most were parenchymatous with markedly enhancement. Calcification may be found, but cystic changes and hemorrhage were very rare.Conclusion The ventricular meningiomas have characteristic imaging features. CT and MRI are valuable in diagnosis, especially MRI.

Objective To explore a new surgical approach for the renovation of laryngotracheal stenosis. Methods the anatomical structures of the anteroventral portion of the digastric muscle along with the blood supply, innervation and periosteal coverage of the mandibular were investigated by observing 23(46 sides) cadaver. Results The anteroventral portion of the digastric muscle rise from the fossae digastrica at the angle of 30.4°±3.5°. Its length was (4.8+0.7) cm and the periosteal coverage averaged (111.6+28.2) mm2. The puncta of rami digastricus stats (2.4+0.7) cm from the arteriae submentalis. Mylohyoid nerve together with rami digastricus enters the muscular tissue. Conclusion Designed with reference to sternocleidomastoid clavicular periosteal flap, the periosteal flap of the anterovent of the digastric muscle-mandible may offer a new way for largngotracheal renouation.

Objective To evaluate the clinical and endocrine effectiveness of different laser doses for ultrasound-guided transvaginal ovarian interstitial laser treatment in patients with polyeystic ovary syndrome (PCOS). Methods Between January 2005 and July 2007, 56 women with clomifene citrate-resistant PCOS selected from the patients who were referred to Shenzhen Maternity and Child Healthcare Hospital with a request for fertility underwent ultrasound-guided transvaginal ovarian interstitial laser treatment. All subjects were randomly divided into four groups of A, B, C and D. In group A, one coagulation point per ovary was done and group B, two points; group C, three points; group D, four to five points. The size of each point was about 10 mm in diameter (the electrical laser was projected persistently for 1-3 min with a power of 3-5 W) . The serum sexual hormone level, ovulation rate and pregnancy rate within six postoperative months were compared among the four groups. Results (1) The spontaneous ovulation rates of groups A (0) and B (21%) within six postoperative months were significantly lower than groups C (71%, P <0.05) and D (79%, P<0.01). The accumulative pregnancy rates of group C (43%) and D(36%) for six postoperative months were significantly higher than group A(0; P <0.01 ,P <0.05). Although they were also higher than that of group B, no statistical significance was found (P>0.05). (2) No statistically significant differences were found among four groups when various preoperative hormone values were compared (P>0.05). The mean serum luteinizing hormone (LH), testosterone level and LH/ follicle stimulating hormone (FSH) ratio was significantly lower postoperatively in groups C [(6.3±2. 6) U/L, (2.2±0.7) nmol/L, 1.1±0.3] and D [(5.8±2.5) U/L, (2.1±0.4) nmol/L, 1.0±0.4] than in groups A [(11.9±3.1)U/L,(3.9±1.6)nmol/L,2.1±0.5] and B [(10.4±3.9)U/L,(3.3±1.1) nmol/L, 2. 0±0.6],respectively(P<0.05). The mean LH, testosterone level and LH/FSH ratio reduced more obviously in groups C (42%,39% and 42% ) and D(53% , 40% and 58% ) than in groups A (4%, 9% and 16%)and B(11%, 6% and 5%;P<0. 05). All above-mentioned parameters between groups C and D had no statistical significant difference (P>0.05). Conclusions One and two intracvarian laser coagulation points per ovary are associated with poor results. Three points per ovary seem to represent the plateau of effective dose for the ovarian interstitial laser treatment. Increasing the dose above it does not improve the outcome.

Objective To identify primary gout biomarkers. Methods Isobaric tags for relative and absolute quantitation (iTRAQ) technique combined with liquid chromatography-tandem mass spectrometry (LC-MS/MS) was used to screen differentially expressed proteins, and to identify potential biomarkers by analysis of the biological process, cellular components, molecular functions, KEGG pathways and protein-protein interactions. Difference between two groups were measured byt test. Results We identified 95 differentially expressed proteins (50 up-regulated proteins and 45 down-regulated proteins, respectively), and 20 significant KEGG pathways. Among them, glyceraldehyde-3-phosphate dehydrogenase (GAPDH), α-enolase (ENOA), phosphoglycerate kinase (PGK1), glucose-6-phosphate isomerase (G6PI) and moesin might play a role in the pathogenesis of primary gout. Conclusion iTRAQ technology can detect differentially expressed proteins from proteome, provides a strong theoretical basis for the study of biomarkers and evidence for the mechanisms in primary gout. However, further studies are needed.

BACKGROUNDTo study the clinical features and more reasonable typing criteria for patients with chronic severe hepatitis and decompensated liver function.

METHODSData of 106 cases of decompensated cirrhosis, 124 cases of chronic liver failure and 100 cases of chronic liver failure (chronic liver failure group I, CLF I) with decompensated cirrhosis (chronic liver failure group II, CLF II) were analyzed retrospectively.

RESULTS(1) The ages were youngest in chronic liver failure group I (about 30 years), and the oldest in decompensated cirrhosis group (about 50 years). (2) There were significant differences in albumin, globulin, ALT, AST, protruding activity, blood glucose, blood lipid and cholinesterase among the three groups. (3) There was no significant difference in upper digestive tract bleeding and hepatorenal syndrome, on the other hand, there was significant difference in ascites and hepatic encephalopathy. (4) The prognosis of the patients in decompensated cirrhosis group was better than that of chronic liver failure group I and chronic liver failure group II.

CONCLUSIONThe clinical feature and prognosis in three groups were different, so, it is suggested that chronic severe liver disease be divided into 2 types: one is chronic severe liver disease type I, which is associated with chronic hepatitis, and the other is chronic severe liver disease type II, which is associated with cirrhosis, and the typing criteria for decompensated cirrhosis remains unchanged.

OBJECTIVETo explore the safety and curative effects of autologous bone marrow-derived mesenchymal stem cells (BMSCs) in the treatment of silicosis.

METHODSThe protocol was approved by the Ethics Committee of the hospital, and ten patients with silicosis who had given written consent were enrolled in this study. BMSCs isolated from 100 ml of bone marrow for each case were purified and cultured. In each case the 3rd generation of qualified BMSCs (5 × 10(7)) were intravenously administered weekly for 3 weeks. Three cases among 10 patients were treated with BMSCs modified by hepatocyte growth factor (HGF) gene. The clinical symptoms, chest films, chest CT, pulmonary functions, T cells, serum IgG and ceruloplasmin (CP) were observed in 6 or 9 months after treatment.

RESULTSNo obvious sub-effect was observed in cases treated with BMSCs, the clinical symptoms (such as cough, sputum and chest tightness) basically disappeared in 9 months after treatment. Pulmonary function tests showed that FVC increased from 71.2% ± 17.0% to 84.0% ± 10.9% (P < 0.01) and FEV1.0 increased from 67.5% ± 17.7% to 80.6% ± 14.9% (P < 0.01). The levels of serum CP and IgG significantly decreased (P < 0.01). Further, the chest films and CT in cases treated with autologous BMSCs modified by HGF gene were improved to different extent.

CONCLUSIONTreatment with autologous BMSCs modified by HGF gene exhibit a beneficial effect on silicosis.

OBJECTIVESTo evaluate the efficacy and toxicity of the B-NHL-BFM-90 protocol in the treatment of Chinese childhood and adolescent B-cell non-Hodgkin's lymphomas (B-NHL).

METHODSForty-two untreated childhood and adolescent B-NHL were enrolled in the present study. Of them 18 cases were Burkitt's lymphoma, 16 diffuse large B cell lymphoma and 8 anaplastic lymphoma. There were 10 cases in stage II and 32 in stage III/IV. The patients were grouped by risk factors into low, medium and high risk groups. All patients were treated with the B-NHL-BFM 90 (Berlin-Frankfurt- Münster) protocol. The low risk group received A, B courses for 4 cycles, the medium risk group AA, BB courses for 6 cycles, and the high risk group AA, BB, CC courses for 6 cycles.

RESULTSComplete remission (CR) was obtained in 37 patients (88%), and partial remission (PR) in 5 (12%). Of the 5 PR patients, I received autologous hematopoietic stem cell transplantation, 3 received radiotherapy for residual disease and 1 just under watching. Major toxicity was myelosuppression and mucositis, especially in AA, BB and CC cycles, but was tolerant and manageable. Median follow-up was 20 (4 - 89) months. Kaplan-Meier method was used to analyse survival data. Two year event free survival (EFS) for all patients was 86. 24%, being 100% for stage II and 80.95% for stage III/IV.

CONCLUSIONShort term and intensive chemotherapy can improves the efficacy and survival rate of childhood and adolescent B-NHL, especially for advanced stage patients.

Acute lung injury(ALI)is a critical respiratory disorder characterized by progressive respiratory failure with high morbidity and mortality.In addition to respiratory support, ALI still lacks effective medications.Natural polyphenol, a class of natural compounds widely found in human daily food, have been proven to possess anti-inflammatory, anti-oxidant, regulating cell death, anti-pathogen infection, and exert therapeutic effects on ALI.This article reviews the pathogenesis of ALI and the mechanism of natural polyphenols in the treatment of ALI, aiming to provide a new direction for the treatment of ALI.

Objective To study the anatomical classification and surgical management of communicating tumors invading the anterior or middle skull base. Methods According to the location and growth direction of the tumors, the communicating tumors invading the anterior or middle skull base in 29 patients were classified into 4 types, namely fronto-naso-orbital tumors in 16 cases, middle-lateral cranial base tumors in 8 cases, central-medial skull base tumors in 4 cases and petrous bone-jugular foramen tumor in 1 case. Based on this classification, extended transbasal approach (13 cases), supraorbital-pterional approach (9 cases), fronto-temporal approach (3 cases), ffontotemporal-orbitozygomatic approach (3 cases) and transpetrol approach (1 case) were adopted for tumor resection and skull base defect reconstruction. In the transbasal approach group, the surgery was performed also through transnasal endoscopic approaches. Results Twenty-four patients underwent total tumor resection and 5 had subtotal tumor resection. No operative death or serious complications (e.g. intracranial infection, cerebrospinal fluid leakage or meningoencephalocele) occurred after the operations. Conclusion Classification of the communicating tumors invading the anterior or middle skull base according to their location and growth direction facilitates planning of the surgical approaches for tumor resection and skull base defect reconstruction.
