Objective To compare the effectiveness and safety of different intracranial stents assisted coil embolization of intracranial aneurysms and to discuss the selection of different stent assisted embolization of intracranial aneurysm.Methods From 2007 April to 2012 April,118 cases (a total of 128 wide-neck aneurysms) with intracranial aneurysms were analyzed retrospectively.This included the use of 70 neuroform,38 Enterprise,and 20 Solitaire AB stents forthe treatment of intracranial aneurysms.The successful use,aneurysm occlusion at the immediate post-operation,and early period of peri-operative complications were recorded from those clinical data in order to assess the effectiveness and safety of the different intracranial stents,which assisted coil embolization of intracranial aneurysms.Rank sum test and x2 test were used for statistics.Results Three aneurysms assisted with Neuroform stent were planted unsuccessfully,and the Enterprise and Solitaire stents were placed successfully.The embolism results of three stents after immediate postoperative angiography aneurysm: Neuroform stent occlusion rate was 40.0％ (28/ 70),the tumor residual rate was 38.6 ％ (27/70),and the partial embolization rate was 21.4 ％ (15/70) ; The Enterprise stent occlusion rate was 42.1％ (16/38),the tumor residual rate was 36.8 ％ (14/38),and the partial embolization rate was 21.1％ (8/38).The Solitaire AB stent occlusion rate was 40.0 ％ (8/20),the tumor residual rate was 35.0 ％ (7/20),and the partial embolization rate was 25.0 ％ (5/20).There were not significant differences in aneurismal occlusion (H =0.12,P ＞ 0.05).Early peri-operative complications results were: Neuroform stent occurred in 7,Enterprise frame in 4,and Solitaire AB stent occurred in 2.There were no significant differences in the incidence of complications in the early period after coiling (x2 =0,P ＞ 0.05).Conclusions Three kinds of intracranial stents assisted embolization of intracranial aneurysms are applied safely and effectively.The stent may be chosen according to morphology of parent artery and stent biological character.

UNLABELLEDOBJECTIVE : To study the anti-atherosclerotic mechanism of bear bile powder (BBP) in Shexiang Tongxin Dripping Pill (STDP) , and to provide scientific evidence for treating atherosclerosis (AS) by its therapeutic characteristics of cool resuscitation.

METHODSAS model was duplicated using ApoE-/- gene knocked mice fed with high-fat diet. Thirty ApoE-/- deficient male mice were divided into four groups according to body weight using random digit table, i.e., the model group (A, n =9), the STDP group (B, n=E7), the STDP without BBP group (C, n =7), and the BBP group (D, n =9). Besides, another 9 C57BL/6J male mice of the same age were recruited as a normal control group (E). All mice in Group B, C, and D were respectively administered with corresponding drugs (30, 30, and 0. 33 mg/kg) by gastrogavage. Equal volume of normal saline was administered to mice in Group A and E. All medication lasted for 8 successive weeks. Serum levels of inflammatory cytokines such as interleukin 2 (IL-2), interleukin 6 (IL-6), tumor necrosis factor a (TNF-α), interferon y (IFNγ), and oxidized low-density lipoprotein (ox-LDL) were measured by ELISA. Serum levels of malondialdehyde (MDA), activities of glutathione (GSH) and superoxide dismutase (SOD) were determined using biochemical assay. Contents of reactive oxygen species (ROS) in the aortic root was detected by dihydroethidum (DHE) fluorescent probe. Expression levels of microRNAs (such as miR-20, miR-21, miR-126, and miR-155) were detected by real-time PCR.

RESULTSThe fluorescence intensity of the aorta was obviously enhanced in Group A. But it was obviously attenuated in Group B, C, and D, and the attenuation was the most in Group B. Compared with Group E, serum levels of IL-2, IL-6, TNF-α, IFN-γ, oxLDL, and MDA all increased (P <0. 01), GSH contents and SOD activities decreased (P <0. 01), expression levels of miR-126, miR-21, and miR-155 in aorta increased (P <0. 01), and the expression level of miR-20 decreased in Group A (P<0. 01). Compared with Group A, serum levels of IL-2, IL-6, TNF-α, IFN-γ, oxLDL, and MDA were all down-regulated (P <0. 01), GSH contents and SOD activities were up-regulated (P <0. 01), expression levels of miR-126, miR-21, and miR-155 in aorta were down-regulated in Group B, C, and D (P <0. 01). The expression level of miR20 was up-regulated in Group B and D (P <0. 01). Compared with Group B, serum levels of IL-2, IL-6, TNF-α, IFN-γ increased (P <0.01); GSH contents and SOD activities decreased, levels of MDA and oxLDL increased (P <0. 01) in Group C and D. Expression levels of miR-20 and miR-155 were down-regulated in Group C and D (P <0. 01).

CONCLUSIONSSTDP played roles in significantly regulating inflammatory factors and oxidative stress factors. Its mechanism might be possibly associated with regulating expressions of miR-126, miR-21, miR-155, and miR-20 in aorta. BBP played significant roles in STDP.

OBJECTIVETo investigate the safety and efficacy of the transabdominal-hiatal approach of radical gastrectomy for the advanced proximal gastric cancer.

METHODSThe clinical data of 40 advanced proximal gastric cancer patients with involvement of distal esophagus admitted in Tongcheng People's Hospital from June 2003 to September 2006 were analyzed retrospectively. Patients included 27 men and 13 women with a mean age of 56.1 years (range: 37 to 76 years). The data were compared with those of 40 proximal gastric cancer patients undergoing standard thoracoabdominal approach (control group) during the same period.

RESULTSAs compared with the control group, the transabdominal-hiatal approach showed less blood loss [(181.3 ± 63.7) ml vs.(248.8 ± 79.7) ml], shorter operating time [(4.1 ± 0.6) h vs. (5.3 ± 0.7) h], shorter ICU stay [(6.5 ± 5.7) d vs. (19.4 ± 18.0) d] and shorter postoperative hospital stay [(14.0 ± 2.3) d vs.(18.7 ± 3.0) d] (all P<0.05). The complication rates of transabdominal-hiatal approach group and thoracoabdominal approach group were 7.5% (3/40) and 10.0% (4/40), and the 5-year survival rates were 51.3% and 60.0%, respectively (both P>0.05).

CONCLUSIONThe transabdominal-hiatal approach of radical gastrectomy for proximal gastric cancer is safe and effective, which may substitute the standard thoracoabdominal technique.

OBJECTIVETo investigate the effect of the combination therapy of biofeedback with electrical stimulation on chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) through clinical trials.

METHODSA total of 140 cases of diagnosed CP/CPPS were randomly divided into a control group (n = 20), a biofeedback group (BF, n = 40), an electrical stimulation group (ES, n = 40), and a biofeedback plus electrical stimulation group (BF + ES, n = 40). The latter three groups were treated by corresponding methods 5 times a week for 2 weeks, while the controls left untreated. After the treatment, all the patients were followed up for 30 days. The NIH chronic prostatitis symptom index (NIH-CPSI) scores and the results of uroflowmetry were obtained and compared before and after the treatment.

RESULTSCompared with the control group, the scores on pain, urinary symptoms and quality of life (QOL) and the total NIH-CPSI scores were obviously decreased (P < 0.05), and the maximum flow rate (MFR) markedly improved (P < 0.05) in the BF, ES and BF + ES groups after the treatment, with significant differences between the former two and the latter one (P < 0.05), but not between the BF and ES groups (P > 0.05), nor in the control group before and after the treatment (P > 0.05).

CONCLUSIONThe combination therapy of biofeedback with electrical stimulation has a synergistic effect on CP/CPPS by alleviating pain and urinary symptoms, improving QOL and elevating MFR.

OBJECTIVETo investigate the effects of oxymatrine on hepatic gene expression profile in a rat model of liver fibrosis.

METHODSForty healthy male SD rats were randomly divided into three groups, a normal group (n=8), a model group (n=16), and an oxymatrine treatment group (n=16). Experimental hepatic fibrosis was induced by subcutaneous injection of carbon tetrachloride (CCl(4)). The rats in the treatment group received oxymatrine via celiac injection at a dosage of 40 mg/kg once a day at the same time. The rats in the model and normal groups received saline at the same dosage via celiac injection. Serum levels of aspartate aminotransferase (AST), alanine transaminase (ALT), alkaline phosphatase (AKP), hyaluronic acid (HA), and laminin (LN) were assayed. The deposition of collagen was observed with HE and Masson staining. Effect of oxymatrine on hepatic gene expression profile was detected by oligonucleotide microarray analysis with Affymetrix gene chip rat U230A. Quantitative real-time polymerase chain reaction (QRT-PCR) was carried out to confirm the expression changes of six genes.

RESULTSOxymatrine significantly improved liver function, lowered serum levels of HA and LN, and decreased the degree of liver fibrosis, compared with the model group (P<0.05). A total of 754 differentially expressed genes were identified by gene chip between the model group and the normal group, among which 438 genes increased and 316 genes decreased over two folds. Compared with the model group, 86 genes were downregulated markedly in the oxymatrine group (P<0.05), including collagen I and other genes related to extracellular material (ECM), integrin signal transduction genes, early growth response factor genes, and proinflammatory genes; 28 genes were upregulated significantly (P<0.05), including cytochrome P450 (CYP450) superfamily genes, glycolipids metabolism and biological transformation related genes. Six genes were confirmed with QRT-PCR, consistent with the result from microarray.

CONCLUSIONOxymatrine could affect the expression of many functional genes and may be useful in the prevention and treatment of liver fibrosis.

OBJECTIVETo investigate flap survival after transfection using gene encoding vascular endothelial growth factor (VEGF).

METHODSIn 30 Sprague-Dawley rats, the anterior abdominal skin flap supplied by the epigastric vessels was created. The animals were divided into three groups, with ten of each. The first group was treated with a mixture of liposomes and the cDNA encoding the 165-amino acid isoform of VEGF; the second group was treated with control blank plasmid DNA and liposome transfection medium; the third group was treated with physiological saline. Four days after injection, the epigastric artery and vein were ligated and the blood flow in the flap was evaluated by intraperitoneal injection of fluorescence solution. Seven days later, the survival area of the flap was measured by planimetry. After the animals were killed, specimens were harvested from the anterior abdomen skin flap for immunohistological evidence of VEGF expression and for hematoxylin and eosin staining of microvascular growth.

RESULTS30 minutes after pedicle ligation the average fluorescence staining planimetry of the three groups (PCD-VEGF165, PCD and physiological saline) was 60.64%, 30.15% and 29.89% respectively. Tissue survival planimetry of the three groups was 92.3%, 30.5%, 31.8%. There was significant difference between the first group and the latter two (P < 0.05). Immunohistochemical staining documented increased deposition of VEGF cDNA in the first group compared to the control groups (P < 0.05). Normal staining documented that the average vessel number of the three groups was 101.72, 91.35 and 89.85 (P < 0.05), the average vessel lumen diameter was 26 microns, 31.09 microns and 32.51 microns(P < 0.05).

CONCLUSIONThrough administration, PCD-VEGF165 can transfect the anterior abdominal skin flap and enhance its survival. There was express of VEGF protein in the treated flap.

OBJECTIVETo explore the dynamic changes of serum interleukin-6 (IL-6) and IL-8 in acute traumatic brain injury (TBI) and their correlations to the severity of brain injury and the condition of the patients.

METHODSThirty-four patients with acute TBI were divided into two groups according to the Glasgow Coma Scale (GCS) score, clinical manifestations and the imaging data, namely patients with GCS score < or = 8 and those with GCS score between 9 and 12. Radioimmunoassay was employed to determine the serum levels of IL-6 and IL-8 at 6 different time points within 15 days after the injury in the two groups.

RESULTSThe serum IL-6 reached the peak level on the second day after the injury in patients with GCS score < or = 8 and on the 7th day in patients with GCS score of 9-12, showing significant differences in IL-6 variations between the two groups (P=0.046). The peak serum level of IL-8 occurred on the 7th day in patients with GCS score < or = 8 and on the 3rd day in patients with GCS score of 9-12, also showing significant differences (P=0.045). The peak level of IL-6 on the second day after the injury was significantly higher than the peak level of IL-8 that occurred on the 7th day, demonstrating significant differences in the variations of IL-6 and IL-8 after the injury (P=0.000).

CONCLUSIONThe changes of serum IL-6 and IL-8 levels show positive correlations to the severity of the condition of the patients sustaining TBI. IL-6 variation is more obvious than that of IL-8 without intimate correlations between them. Clinically, serum IL-6 level can be more informative than serum IL-8 level in evaluating the changes of the condition of the TBI patients in early stage following the injury.

OBJECTIVETo discuss the diagnosis and treatment of inflammatory myofibroblastic tumor (IMT) of the prostate.

METHODSWe retrospectively analyzed the clinical data of a case of IMT of the prostate and reviewed relevant literature. The patient was a 62-year-old man, who was twice referred to the local hospital for recurrence of dysuria. He was diagnosed as with benign prostatic hyperplasia (BPH) and twice underwent transurethral resection of the prostate (TURP). But frequent recurrence of dysuria followed postoperatively, for which he came to our hospital and received another TURP and transurethral resection of the bladder tumor (TURBT). Pathological findings showed chronic inflammation of the bladder, papillary hyperplasia with mild dysplasia in regional urothelial and IMT of the prostate. Six months later, the patient came again to our hospital for recurrence of dysuria. Computed tomography revealed a large mass in the bladder.

RESULTSThe patient underwent laparoscopic bladder radical resection and ileal conduit diversion, simultaneously with pelvic lymph node dissection. The pathological examination confirmed it to be an IMT of the prostate with the bladder but not regional lymph nodes involved. An 11-month follow-up showed neither local recurrence nor distant metastasis.

CONCLUSIONIMT of the prostate is a rare borderline lesion, whose diagnosis is very difficult and mainly depends on pathological findings. IMT of the prostate is liable to recur and even invade the bladder. Radical resection is recommended for patients with large and recurrent tumors, and close follow-up is strongly warranted.

?AlM: To investigate repeatability and accuracy of a latest Keratograph for evaluating the tear film stability and to compare its measurements with that of traditional examination methods.
?METHODS: The results of noninvasive tear film break-up time ( Nl-BUT ) including the first tear film break-up time ( BUT-f ) and the average tear film break-up time ( BUT - ave ) were measured by Keratograph. The repeatability of the measurements was evaluated by coefficient of variation ( CV ) and intraclass correlation coefficient ( lCC) . Wilcoxon Signed-Rank test was used to compare Nl-BUT with fluorescein tear film break-up time ( FBUT) to confirm the correlation between Nl-BUT and FBUT, Schirmer l test values. Bland-Altman analysis was used to evaluate consistency.
?RESULTS: The study recruited 48 subjects ( 48 eyes ) (mean age 38. 7±15. 2 years). The CV and lCC of BUT-f were respectively 12. 6% and 0. 95, those of BUT-ave were 9. 8% and 0. 96. The value of BUT-f was lower than that of FBUT. The difference had statistical significance ( 6. 16±2. 46s vs 7. 46±1. 92s, P<0. 01). There was significant positive correlation between Nl-BUT and FBUT, Schirmer l test values ( P< 0. 01 ). The scope of 95% limits of agreement (LoA) was 4. 46s in BUT-f and FBUT, while the scope of LoA was 3. 64s in BUT-ave and FBUT.
?CONCLUSlON: Keratograph can provide Nl-BUT data that has a better repeatability and reliability, which has great application prospects in diagnosis and treatment of dry eye and refractive corneal surgery.
