Objective To investigate the existence of neglect and explore the relationship between spacial attentional deficits and hemisphere in patients with schizophrenia. Methods 51 schizophrenic patients and 55 healthy controls were measured with line bisection test and number bisection test、 Results In the Line Bisection Test,shcizophrenic patients group showed a negative deviation, in which the 2cm line( -0.03 ± 0. 74 )% and mean ( - 0. 02 ± 0. 03 ) % deviation rates were more significantly leftward than that of the normals ( ( 0. 00 ±0.02 ) %, ( - 0.00 ± - 0.01 ) %, P ＜ 0. 05 ) respectively. The mean deviation rates of the patients (P ＜ 0. 01 ) and control groups (P ＜ 0. 05 ) were also significantly leftward compared with zero value. In the number bisection test,schizophrenic patients group showed a negative deviation and a significant leftward bias on the interval 5 ( - 0.07 ±0.18)% ,7( -0.08 ±0.22)% and 9( -0.09 ±0.28)% ) than that of the normals(( -0.01 ±0.05)% ,(0.01± 0. 08 ) % and (0.00 ± 0.14 ) %, P ＜ 0.05 respectively). Conclusion Schizophrenic patients have a right-neglect, suggesting that spacial attentional deficits exist, and it may be related to the left cerebral hemisphere dysfunction.

Objective To compare the results of the anterior approach (AA) with the conventional approach in the treatment of large hepatocellular carcinoma (HCC).Methods We searched the Medline,PubMed,Cochrane Library,Wanfang database on randomized clinical controlled trials and non-randomized clinical controlled trials comparing AA with the CA in right hepatic resection for large hepatocellular carcinoma.The data were analyzed with the RevMan5 software.Results Five non-randomized clinical controlled trials (NRCTs) and three randomized clinical controlled trials involving 615 patients (304 in the AA group,311 in the CA group) were enrolled into the analysis.There was no significant difference in the operation time between the two groups.Compared with the CA,the AA had lower intraoperative blood loss (WMD=-680.2 ml; 95％CI,-1023.97～-336.43;P=0.0001),blood transfusion rate (OR=0.38;95％ CI,0.25～0.59;P＜0.0001),intraoperative tumor rupture (OR=0.33;95％CI,0.11～0.97;P=0.04),surgical complication (OR=0.59;95％CI,0.38 ～ 0.93 ; P =0.02),hospital mortality (OR =0.37 ; 95 ％ CI,0.21 ～ 0.67 ; P =0.0009),and hospital stay (WMD=-4.75 d;95％CI,-7.82～-1.67;P=0.002).Conclusion AA is superior to CA in the treatment of larger.The operation time is the same for the 2 approaches.

Objective To understand the mechanism of cerebral energy failure after hypoxia ischemia at the molecular level and to establish the protocol for the safe and effective treatment of hypoxic-ischemic encephalopathy(HIE).Methods One hundred neonatal rats were divided into normal control group and hypoxic-ischemic(HI) group. SD rats of both groups were decapitated at the time of 2 h,24 h,48 h,72 h and 7 d after HI.These tissues of cerebrum,cortex and hippocampus were taken out to explore the influence of HI on the expression of GLUT1 and GLUT3 genes with the method of RT-PCR.Results There was an enhancement in the expression of GLUT1 and GLUT3 genes with the increasing of day age. The expression was more intense in hippocampus than that in cortex. However, HI could significantly enhance the expression of GLUT genes. The expression was higher in cortex than that in hippocampus. The expression of two genes reached the peak at 24 h after HI, but was significantly lower than that in control group at 7 d after HI.Conclusion The increased expression of GLUT genes can maintain the energy supplement for the brain and delay a cascade reaction of cerebral energy failure.

Objective To investigate the auxoaction and mechanism of CDllc+DCs on psoriasis. Methods CDllc+ DCs in the psoriasis-like lesions were confirmed by immunofluorescence double staining experiments. The CD1lc+ DCs were subcutaneously injected into the neck skin of transgenic mice without disease. The clinical features were observed and assessed with PASI score every day. The ear and back skin were checked by HE stained. At the same time, the T lymphocyte and DCs of bone marrow, spleen, submandibular lymph nodes and blood were analyzed by flow cytometry, and the T lymphocyte in the skin lesions were analyzed by immunofluorescence. The heart, liver, spleen, lungs and kindey were HE stained. Results In the psoriasis-like lesions, about 90％ CDllc+ cells expressed CDllc. HE test showed that the thickness of the skin layer was significant different between the experimental group (ear: 29±4 μm; back: 25±3 μm) and the control group(ear: 11±2 μm; back: 9±1 μm) (P＜0.01). CD3 + CD4+ T lymphocyte cells in the blood of the experimental mice (17.87％) were decreased significantly (P＜0.01) compared with the control group mice (31.77％). The numbers of Thl and Th17 cells from bone marrow, spleen, submaxillary lymph nodes and blood, as the same as CD1lc+DCs from bone marrow and submaxillary lymph nodes, were decreased in the experimental mice compared with the control group mice (P＜0.01). The number of CD4﹢T cells, CD8+T cells, IL-17a+cells and IFN-γ+cells in the skin lesions from the experimental group all were higher than that from the control group (P＜0.01). And the vessels in the lesions of the experimental group were higher than that in the control group (P＜0.01). Conclusions CD1 lc+CD1 lc+DCs may play an important role in the occurrence and development of psoriasis by increasing the T lymphocyte and the blood vessel in the skins of K14-VEGF transgenic mice.

OBJECTIVETo establish a reliable model for drug screening and therapy by culturing rat femoral head and inducing cartilage degeneration quickly in vitro.

METHODSThe femoral heads from the same SD rats of two-month old were divided into control group and experimental group respectively. They were cultured with DMEM medium plus 10% fetal bovine serum or DMEM medium plus 10% fetal bovine serum plus 50 ng/ml IL-1β for three days. Femoral heads were fixed in 4% paraformaldehyde, decalcified, dehydrated, embedded in paraffin and cut into slices. Specimens were stained with Toluidine blue and Safranine O-Fast Green FCF. The protein expression levels of type II collagen, MMP13, Sox9 and ADAMTS5 were analyzed by immunofluorescence.

RESULTSBoth the Toluidine blue and Safranine O staining were pale in the margin of femoral heads which were stimulated with IL-1β for three days compared to that in control group. The Fast Green FCF staining was positive at the edge of the femoral head in experimental group, which indicated that cartilage became degenerated. The expression levels of both type H collagen and Sox9 were decreased significantly while the expression levels of MMP13 and ADAMTS5 were increased in experimental group.

CONCLUSIONThe model of cartilage degeneration is established by culturing and inducing the degeneration of the femoral heads quickly in vitro.

OBJECTIVETo explore the clinical roles of Jiawei Shentong Zhuyu Decoction (JSZD) in preventing the occurrence of failed back surgery syndrome (FBSS), and to observe its effect on serum tumor necrosis factor-alpha (TNF-alpha).

METHODSTotally 100 patients prepared for surgical operation due to lumbar intervertebral disc herniation were randomly assigned to the treatment group and the control group according to random number table, 50 cases in each group. Patients in the treatment group additionally took JSZD, one dose per day, taken in two portions, once in the morning and once in the evening. Those in the control group took Celecoxib Capsule (200 mg each time, once per day) and Mecobalamin Tablet (0.5 mg each time, 3 times per day). They only took Mecobalamin Tablet from the 11th day. All patients were treated for 30 days. Japanese Orthopaedic Association (JOA) score was performed before treatment, at week 1, after treatment, at 6 months of followed-ups, and at 12 months of followed-ups. And the levels of TNF-alpha in the peripheral blood were observed before treatment and at one month after treatment.

RESULTSTotally 93 patients completed the followed-up study. The JOA scores were improved after treatment, at 6 and 12 months of followed-ups (P < 0.05, P < 0.01). The JOA score at 6 months of followed-ups was superior in the treatment group to that of the control group (P < 0.05). Five patients (accounting for 10.6%) suffered from FBSS in the treatment group, while 9 (accounting for 19.6%) suffered from FBSS in the control group. The treatment group was superior to the control group (P < 0.05). The TNFalpha level was improved after treatment in the two groups. Of them, the improvement of TNF-alpha in the treatment group was better than that of the control group (P < 0.05).

CONCLUSIONThe application of JSZD was effective for preventing the occurrence of FBSS, and improved the serum TNF-alpha level.

OBJECTIVETo evaluate the efficacy and safety of Chaihu Xiaoyao Mixture (CXM) for the treatment of major depressive disorder (MDD).

METHODSOne hundred and ninety patients with MDD were randomly assigned to two groups, the test group and the control group. They were treated by paroxetine combined with CXM or placebo for 8 weeks. The therapeutic efficacy was evaluated at the end of the 2nd, 4th and 8th week by scoring according Hamilton Rating Scale for Depression (HAMD-17) and Clinical Global Impression (CGI) scale, and the adverse reaction was scaled by Treatment Emergent Symptoms Scale (TESS).

RESULTSFollow-up study was completed in 89/92 patients in the test group, and 93/98 patients in the control group, with 3 and 5 cases dropping, respectively. The effective rate in the two groups was 84.8% and 71.4%, and the cure rate was 69.6% and 55.1%, respectively, which were significantly higher in the test group than in the control group (chi2=4.92, P<0.05; chi2=4.22, P<0.05). As compared with the baseline, significant differences in HAMD-17 total score and scores of its various factors as well as the CGI score were shown in both groups after 2, 4 and 8's week treatment (P<0.01). Comparison between groups showed that significant differences presented in HAMD-17 total score and CGI score at the end of the 8th week (P<0.01), while comparison of adverse reactions between groups showed insignificantly statistical difference (P>0.05).

CONCLUSIONCombined treatment of CXM and paroxetine is more effective than that with paroxetine alone in treating MDD, and it could enhance the clinical efficacy with higher safety.

OBJECTIVETo investigate the effects of antibiotic-PMMA (polymethyl-methacrylate) beads combined with external fixator in treatment of infected fracture nonunion.

METHODSTwenty-two cases of infected fracture-nonunions were reviewed involving 20 male and 2 female with an average age of 34.68 years (ranging 21 to 74 years). The data consisted of 9 cases of tibial fractures, 2 distal fractures of the femur, 6 femoral shaft fractures, 3 intertrochanteric fracture of the femur and 2 humeral shaft fractures. The procedure included thorough debridement to wipe out dead bone and granulation tissue, then antibiotic-PMMA bead chains imbedded into the dead space. One week later, secondary debridement was performed, antibiotic-PMMA bead chains were changed according to result of bacterial culture and susceptibility test, and fractures were stabilized with external fixator. Three months after debridement, antibiotic-PMMA bead chains were taken out and bone graft with autogenous iliac cancellous bone chips was performed.

RESULTSThe mean follow-up period was 19.98 months (ranging 15 to 28 months). Infection was controlled in 20 cases. One tibial fracture and 1 intertrochanteric fracture of the femur needed repeated debridement 2 and 3 months after bone grafting respectively,because of infection recurrence and sinus formation. All 22 cases achieved bony union averaged 15.09 weeks after bone grafting with a range of 8 to 24 weeks.

CONCLUSIONThorough debridement, imbedding antibiotic-PMMA bead chains combined with external fixator and staged bone grafting has proven to be effective and simple for treatment of infected fracture nonunion. The antibiotic bead delivers high tissue levels,obliterates dead space, aids bone repair.

OBJECTIVETo evaluate the relationship between epithelial mesenchymal transition (EMT) and lung metastasis in hepatocellular carcinoma.

METHODSThere were 100 patients who underwent surgical resection of hepatocellular carcinoma between January 2000 and March 2004. They were classified with non-distance metastasis and lung metastasis depend on the close following up till March 2007. Their hepatocellular carcinoma specimens were retrospectively examined for EMT markers (E-cadherin, Vimentin, Fibronectin) with immunochemistry staining in tissue microarray. Univariate and multivariate analysis were used for study the relationship between EMT and lung metastasis.

RESULTSUnivariate analysis showed that down regulation of E-cadherin, overexpression of fibronectin, cytosolic expression of vimentin, AFP >or= 400 ng/ml, tumor size more than 10 cm, portal vein involvement, poorly differentiated of tumor had close correlation with lung metastasis. Multivariate analysis indicated that overexpression of fibronectin was independent factor for lung metastasis apart from tumor size more than 10 cm, portal vein involvement and poorly differentiated of tumor.

CONCLUSIONThe results proposed that EMT has close relation with lung metastasis in hepatocellular carcinoma.

OBJECTIVETo explore the prediction of the site for microsurgical vasoepididymostomy (VE) in the treatment of epididymal obstructive azoospermia (OA).

METHODSThis study involved 56 infertile men with confirmed OA whose obstruction was suspected to be in the epididymis. Based on their medical history and results of preoperative physical examination and ultrasonography, we predicted the sites for VE. We performed surgical scrotal exploration for the status of epididymal obstruction, conducted palpation and microscopic observation for the epididymal tubules to be anastomosed, and finally decided on the sites for VE by making sure of the presence of motile sperm in the epididymal fluid of the patients. After surgery, we followed up the patients for the rate of pregnancy.

RESULTSAll the patients received bilateral scrotal ultrasonography and surgical scrotal exploration, totaling 112 procedures, including 98 VE procedures. The accuracy rate of the predicted sites for VE was 80.5% (153/190) by medical history and physical examination, 80.3% (90/112) based on the results of ultrasonography, and 87.4% (90/103) according to the first selected epididymal tubules. Of the 28 patients followed up for more than 12 months, motile sperm were found in 19 (67.9% ) at 2 to 12 months and spontaneous pregnancies were achieved in 10 (35.7%), all with the anastomotic sites in the corpus or cauda.

CONCLUSIONMedical history and physical examination contribute to the selection of anastomotic sites and non-invasive scrotal ultrasonography is effective and practical for positioning epididymal obstruction. The epididymal tubules with motile sperm for anastomosis could be easily obtained from the most dilated ones in indurated epididymides.
