The silent cerebral infarct is an clinic symptom that is so slight or transitory as to be easily neglected. There are only neural symptoms and signs,but irresponsible infarct focus can be seen on image. The risk factors of silent cerebral infarct may be the same as those of symptomatic cerebral infarct. Such infarct is likely to influence the course, clinic symptom and prognosis of acute cerebral infarct and may foretell symptomatic cerebral infarct and deteriorate into pseudo-global paralysis or multi-infarcted dementia. Therefore elder who suffer from hypertension or diabetes and experience vertigo, headache, language barrier but without apparent signs and symptoms should receive cerebral CT or MRI. Minor or third-degree precautionary measures can be taken as a chief therapy for cerebral infarct. Alternatively vitamines B_6,B_(12) and folic acid can be supplied to reduce the chance of hyperhomocysteinemia. Headache is the initial symptom in silent brain infarct. Magnesium is effective when dehydration does not work.

Objective To investigate the influences of UVA on the secretion and expression of chemokine CXCL11/I-TAC by HaCaT cells induced by interferon γ (IFN-γ) and tumor necrosis factor α (TNF-α). Methods HaCaT cells were cultured in the presence of IFN-7 and TNF-a and irradiated with UVA of 2, 4 and 8 J/cm~2, respectively; those cells receiving neither treatment with IFN-γ or TNF-α nor UVA irradiation served as the negative control, and those receiving only cytokine treatment but no irradiation as the positive control. After another 24-hour culture, enzyme-linked immunosorbent assay (ELISA) was performed to detect the protein levels of CXCL11/I-TAC in the supernatant of HaCaT celb, real time PCR to measure the mRNA expression of CXCL11/I-TAC in these HaCaT cells. Results As far as the negative control HaCaT cells were concerned, there was a minor secretion of CXCL11/I-TAC protein and expression of CXCL11/I-TAC mRNA. After treatment with IFN-7 and TNF-a of 10 μg/L, the protein and mRNA expressions of CXCL11/ I-TAC were synergistically upregulated, whereas the induced secretion and expression of CXCL11/I-TAC by HaCaT cells were dose-dependently inhibited by UVA irradiation. Conclusions UVA irradiation inhibits the secretion and expression of CXCL11/I-TAC by HaCaT cells, which in turn suppresses the chemotaxis of Th1/ Tel cells in some degree.

OBJECTIVETo observe the clinical effect of low-dose once-daily tadalafil combined with Shuganyiyang Capsules in the treatment of mild-to-moderate erectile dysfunction (ED).

METHODSNinety patients with mild-to-moderate ED were equally randomized to groups A, B and C to receive Shuganyiyang Capsules, tadalafil, and tadalafil + Shuganyiyang Capsules, respectively. The scores of the patients on IIEF-5 and SF-PAIRS (15-Item Short Form of Psychological Interpersonal Relationship Scales) were recorded before and at 1 and 3 months after treatment.

RESULTSThe IIEF-5 scores of groups A, B and C were 10.13 +/- 1.55, 11.00 + 1.60 and 10.73 +/- 1.91 before treatment, and 13.77 +/- 2.11, 17.77 +/- 2.13 and 17.17 +/- 3.84 at 1 month after treatment, significantly higher in B and C than in A (P <0. 001) , but with no remarkable difference between B and C (P =0. 411). At 3 months after treatment, the IIEF-5 scores were 15.77 +/- 2.05, 18.07 +/- 2.24 and 19.37 +/- 3.76 in the three groups, dramatically higher in B and C than in A (P <0.001) as well as in C than in B (P<0.05). The scores on sexual self-confidence, sexual spontaneity and time concerns in SF-PAIRS were 3.90 +/-0.80, 8.67 +/- 1.94 and 14.43 +/- 1.92 before medication, 5.83 +/- 1.02, 9.90 +/- 1.75 and 11.17 +/- 1.68 at 1 month and 6.73 +/- 0.98, 11.07 +/- 2.08 and 10.67 +/-1.60 at 3 months after medication in group A; 4.17 +/- 0.87, 9.37 +/-1.43 and 14.47 +/-1.57 before medication, 6.47 +/-0.78, 10.83 +/- 2.18 and 10.20 +/-1.56 at 1 month and 6.83 +/-0.91, 11.30 +/- 1.88 and 9.47 +/- 1.57 at 3 months in group B; and 4.23 +/-0. 94, 9.50 +/- 1.89 and 14.67 +/- 2.91 before medication, 8.03 +/- 1.67, 13.43 +/-1.10 and 9.70 +/-1.21 at 1 month and 8.93 +/- 1.78, 14.70 +/- 1.26 and 8. 87 +/- 0. 97 at 3 months in group C. Compared with the baseline, the SF-PAIRS scores of the three groups were all significantly improved after treatment (P <0. 05) , and markedly higher in C than in the other two groups (P <0.05).

CONCLUSIONLow-dose once-daily tadalafil combined with Shuganyiyang Capsules is obviously effective in the treatment of mild-to-moderate ED, which not only improves the patients'erectile function, sexual self-confidence and sexual spontaneity, but also reduces their time concerns.

Objective To study the clinical significance ofneutrophil gelatinase-associated lipocalin (NGAL), which in serial plasma and urine samples was measured in participants with lupus nephritis (LN)and healthy persons. Methods NGAL in serial plasma and urine samples was measured by enzyme-linked immunosorbent assay (EL.ISA) in 35 patients with LN by 1997 ACR systemic lupus erythematosus (SLE)standard with varied degree of kidney damage and 30 healthy persons with matching sex and age in physical examination center. Disease activity was measured by the SLE disease activity index (SLEDAI-2K),and 35LN patients were classified in active group and (25 cases) non-active group (10 cases) according to the SLEDAI-2K. Results Urinary NGAL were significantly increased in LN patients [(78.94 ± 81.97) μg/L]compared with healthy persons[(28.50 ± 18.08) μ g/L] (P = 0.002). And urinary NGAL were significantly increased in active group [(92.90 ± 94.88) μg/L] compared with non-active group [(48.20 ± 24.77)μ g/L] (P = 0.049). NGAL in serial plasma had no statistically significant difference between active group and non-active group (P ＞0.05). Conclusions NGAL in urine but not in plasma represents a novel biomarker for renal disease activity in LN. The increase might be related to renal tubule pathological changes.

BACKGROUND: Previous animal studies demonstrated that bone marrow mesenchymal stem cells could differentiate into nerve cells under a certain condition; however, the clinical application for treating nervous system disease has been less reported. OBJECTIVE: To observe a short-term effect of autologous bone marrow mesenchymal stem cell transplantation on treating cerebral hemorrhage.METHODS: A total of 32 patients with cerebral hemorrhage who were selected from the Department of Neurosurgery, Liaocheng Brain Hospital between November 2007 and January 2009 were considered as a treatment group. According to general data and the amount of hematoma, they were treated by drilling drainage or hematoma evacuation. Drainage tubes were detained into hematoma cavity, and 3.5 mL autologous bone marrow mesenchymal stem cell suspension was injected through drainage tube. A total of 40 additional patients who did not treated with stem cell transplantation were considered as a control group. Neurologic impairment (NIHSS) and activities of daily living (Barthel index) were performed before and 6 months after transplantation; meanwhile, the brain MRI, serum biochemical and tumor marker were evaluated to detect security of stem cell transplantation. RESULTS AND CONCLUSION: The NIHSS score and Barthel index in the treatment group were similar to those in the control group before transplantation. Compared with control group, NIHSS scores were significantly decreased in the treatment group (P < 0.01), but Barthel index was significantly increased 6 months after transplantation (P < 0.01). Compared with before transplantation, NIHSS score were significantly decreased (P < 0.01), but Barthel index was significantly increased in the treatment group 6 months after transplantation (P < 0.01). Two patients in the treatment group had febrile, which was recovered after treatment. The following-up 6 months after transplantation demonstrated that brain MRI and biochemical indicators were normal except an increasing of CA-153 caused by lung cancer in one patient. The autologous bone marrow mesenchymal stem cell transplantation for treatment of cerebral hemorrhage is safe and effective in a short-term period; however the long-term effect still needs to be further studied.

Pathological neural activity in subthalamic nucleus (STN) is closely related to the symptoms of Parkinson' s disease. Local field potentials (LFPs) recordings from subthalamic nucleus show that power spectral peaks exist at tremor, double tremor and tripble tremor frequencies, respectively. The interaction between these components in the multi-frequency tremor may be related to the generation of tremor. To study the linear and nonlinear relationship between those components, we analyzed STN LFPs from 9 Parkinson's disease patients using time frequency, cross correlation, Granger casuality and bi-spectral analysis. Results of the time-frequency analysis and cross-frequency correlation analysis demonstrated that the power density of those components significantly decreased as the alleviation of tremor and cross-correlation (0.18-0.50) exists during tremor period. Granger causality of the time-variant amplitude showed stronger contribution from tremor to double tremor components, and contributions from both tremor and double tremor components to triple tremor component. Quadratic phase couplings among these three components were detected by the bispectral approaches. The linear and nonlinear relationships existed among the multi-components and certainly confirmed that the dependence cross those frequencies and neurological mechanism of tremor involved complicate neural processes.
