OBJECTIVETo study the effect of Yishen Daluo Decoction (YDD) on the expression of protein lipoprotein (PLP), oligodendrocyte transcription factor 1 (Olig 1), and oligodendrocyte transcription factor 2 (Olig2) in mice with experimental autoimmune encephalomyelitis (EAE).

METHODSTotally 40 mice were randomly divided into 4 groups, i.e., the normal group, the model group, the Chinese medicine (CM) group, and the Western medicine (WM) group, 10 mice in each group. Each mouse in the model, CM, and WM groups was subcutaneously injected with 200 microL antigen emulsion (containing 150 micro g PLP139 -151 and 400 micro g H37RA) in two parts at the upper abdomen on the first day. 100 microLBordetella pertussis juice (containing 0. 6 x 10(6) Bordetella pertussis) was injected by caudal vein on the first and the third day. On the 7th day after modeling, each mouse in the normal group and the model group was intragastrically given normal saline (0. 1 mL/10 g). YDD (0. 2 g crude drug/10 g) was intragastrically given to mice in the CM group, and prednisone (0. 039 mg/10 g) was intragastrically given to mice in the WM group. All mice were intervened for 54 days. Changes of PLP, Olig1, and Olig2 in the brain tissue of EAE mice were detected by Western blot. Results The levels of PLP and Olig2 in the brain tissue of the model group were less than those of the normal group (P <0.05). Compared with the model group, the levels of PLP, Olig1, and Olig2 in the brain tissue increased in the CM group (P <0.05); the levels of PLP and Olig2 in the brain tissue increased in the WM group (P <0.05). Compared with the WM group, the level of Olig1 in the brain tissue increased in the CM group (P <0.05).

CONCLUSIONYDD could enhance remyelination by elevating the levels of Olig1 and Olig2 in the brain tissue of EAE mice.

AIM: To study effect of the Bushen Ningxin decoction, a Chinese medicine, on the adherence of monocytes to endothelial cells and its mechanism. METHODS: Using cultured human umbilical vein endothelial cells (HUVECs) as target cells, oxidized low density lipoprotein (ox-LDL) was added to the endothelial cell culture to prepare the model of human endothelial cell injury. The serum of rabbits having been treated with Bushen Ningxin decoction was added to trial architecture, the adherence of monocyte-like cell line U937 to HUVECs was analyzed using Rose Bengal staining. In addition, the expression of intercellular adhesion molecule-1 (ICAM-1), vascular cell adhesion molecule-1(VCAM-1) and E-selectin in HUVECs was measured by flow cytometry. RESULTS: Treatment of HUVEC with ox-LDL (100 mg/L) for 24 hours significantly increased adhesion of U937 to HUVECs. If serum of the animal treated with Bushen Ningxin decoction was added to trial architecture, the adhesion decreased significantly. The flow cytometry analysis showed that ox-LDL could induce the expression of ICAM-1, VCAM-1 and E-selectin in HUVECs. Serum of the animal treated with Bushen Ningxin decoction significantly decreased the expression of ICAM-1, VCAM-1 and E-selectin in HUVECs. CONCLUSION: The Bushen Ningxin Chinese herb-containing serum has an inhibitory effect on the adherence of monocytes to endothelial cells, probably by way of down-regulating the expression of ICAM-1, VCAM-1 and E -selectin in endothelial cells.

OBJECTIVEs To assess the understanding degree of urologists for benign prostatic hyperplasia (BPH) and the clinical characteristics of BPH patients.

METHODSThe questionnaires was distributed to urologists and patients in 119 hospitals over the country, respectively. The urologist survey was mainly focused on the questions of BPH progression and therapeutic model. The patient survey was mainly focused on the questions of patient's age, symptom features and the preference to receiving treatment.

RESULTSThe evaluations based on 289 completed urologist questionnaires and 4253 completed patient questionnaires showed that 98.6% of urologists agreed that BPH was a progressive disease but there were still some differences in understanding the risk factors for BPH progression. Additionally, 98.1% of patients were diagnosed to be moderate or severe BPH, nocturia was the most frequent symptom. In the treatment for BPH, both the urologists and patients concerned about how to improve the system rapidly.

CONCLUSIONSThis study is the first questionnaires specifically to the urologists and BPH patients, the results would reflect the situations of BPH diagnosis and treatment in China and would be helpful to the development of BPH guideline.

This paper introduces a random measurement analysis of, lung function measurement values with two different apparatus. in 41 patients. It shows that the differences are not statistically significant (P>0.05) between two apparatus measurement values except DLCO, FEF25, FEF75 in the group of normal ventilation, FVC in the group of abnormal ventilation. The two groups are both correlated closely (r> 0.9) except MMF(r=0.7725, RV r=0.808) in the normal group of ventilation, and FEF75 (r=0.58) in the abnormal group of ventilation (p<0.001). The two apparatus with different measuring theories have a good correlation.

OBJECTIVETo study the effects of Bushen Ningxin recipe (BNR) on atherosclerosis in ovariectomized rabbits.

METHODSTwenty-six female New Zealand white rabbits of three months old were randomly divided into four groups, the normal group, the sham operation group, the control group (ovariectomized) and the treated group (ovariectomized and treated with BNR). All rabbits, except the normal group, were fed with high-cholesterol diet starting from two weeks after operation, and to the treated group BNR was given additionally for 3 months. Levels of blood lipid (TC, TG, LDL-C and HDL-C) and NO were measured at the end of the 12th week, and at the same time, histomorphological and pathological examination of aorta under light microscopy and scanning electron microscopy, and the ratio of atherosclerotic area of lesion/endothelium ratio (AL/AE) and thickness of endothelium/medium ratio (TE/TM) were estimated using image analyzer.

RESULTSNo significant difference was found in levels of blood lipid between groups, except those in the normal group. As compared with the control group, in the treated group, level of serum NO was higher, AL/AE and TE/TM were lower and the pathological changes of aorta was milder.

CONCLUSIONBNR could inhibit the atherosclerosis formation in ovariectomized rabbits, it showed protection on vascular endothelial cells.

OBJECTIVETo investigate the effect of bortezomib on prophylaxis of acute graft-versus-host disease (aGVHD) after mouse allogeneic-bone marrow transplantation (allo-BMT) and its mechanism.

METHODSC57BL/6 (H-2(b)) mice were used as donors and BALB/c (H-2d+) mice as recipients. After allo-BMT, the BALB/c mice were divided into 3 groups, ie. group A:BMT control, group B: BMT + early infusion of bortezomib (1 mg kg(-1) d(-1), day 0-3), group C: BMT + late infusion of bortezomib (1 mg kg(-1) d(-1), day 5-7). Clinical manifestations of aGVHD, pathohistological changes, survival rate and levels of recipients H-2(b) cells detected by flow cytometry in the recipient mice were observed. Monodirectional mixed lymphocyte culture (MLC) system was established ex vivo and different concentrations of bortezomib (0, 2, 4, 8 nmol/L) were added to the system. The viability of the cells was detected by CCK-8 assay and cells apoptosis by flow cytometry. The concentrations of IL-2, IFN-gamma, TNF-alpha in the supernatant were detected by enzyme-linked immunosorbent assay (ELISA).

RESULTSThe mice in group A developed typical aGVHD and all died of aGVHD within 3 weeks after transplantation, with a median survival time of (16.1 +/- 2.5) d. The symptoms of aGVHD was milder in group B than in group A, and the median survival time was significantly longer. The 60-day survival rate in group B was 70%, being significantly higher than that in other two groups(P<0.05). The mean value of donor-derived cell (H-2(b) cells) in group B was (98.1 +/- 1.1)% at 60 days. The symptoms of aGVHD was significantly severer in group C than in group A, and the median survival time was shorter. Bortezomib inhibited the cells viability in MLC system in a dose-dependent manner. After treated with 8 nmol/L bortezomib for 24 h, the inhibition ratio of cells viability was (41.4 +/- 6.0)%. The cell apoptosis rate increased gradually with bortezomib treatment for 12 h, 24 h and 36 h. After treated with 8 nmol/L bortezomib for 36 h, the apoptosis rate was (62.8 +/- 7.0)%. After treated for 24 h, the levels of IL-2, IFN-gamma and TNF-alpha in the supernatant were decreased.

CONCLUSIONSBortezomib administered immediately after allogeneic BMT can prevent aGVHD, improve the survival rate and have no influence of engraftment in the recipient mice. Delayed administration of bortezomib results in acceleration of aGVHD-induced mortality. Its mechanism maybe inhibition of the lymphocyte viability, increase of the cells apoptosis rate, and inhibition of secretion of IL-2, IFN-gamma, and TNF-alpha.

High-throughput sequencing was performed for the peripheral blood DNA from two probands in the family with tuberous sclerosis complex (TSC) to determine the sequences of TSC-related genes TSC1 and TSC2 and their splicing regions and identify mutation sites. Amplification primers were designed for the mutation sites and polymerase chain reaction and Sanger sequencing were used to verify the sequences of peripheral blood DNA from the probands and their parents. The two probands had c.3981-3982 insA (p.Asp1327AspfsX87) and c.4013-4014 delCA (p.Ser1338Cysfs) heterozygous mutations, respectively, in the TSC2 gene. The parents of proband 1 had no abnormalities at these two loci; the mother of proband 2 had c.4013-4014 delCA heterozygous mutation in the TSC2 gene, while the father and the grandparents of proband 2 had no abnormalities. c.3981-3982 insA mutation may cause early coding termination of amino acid sequence at the 1413th site, and c.4013-4014 delCA mutation may cause early coding termination of amino acid sequence at the 1412th site. These two mutations are the pathogenic mutations for families 1 and 2, respectively, and both of them are novel frameshift mutations, but their association with the disease needs to be further verified by mutant protein function cell model and animal model.

BACKGROUNDTransurethral resection of prostate (TURP) has been considered as the standard treatment for benign prostatic hyperplasia (BPH). However, issues that have not yet been overcome for TURP include bleeding and absorption of irrigation fluid. Thus, novel improvement of the surgery is necessary. This study aimed to evaluate the efficacy and safety of bipolar plasma vaporization of the prostate (BPVP) with "button-type" electrode against standard TURP for BPH.

METHODSFrom January 2009 to January 2012, 30 patients who scheduled for surgical treatment of BPH surgical treatment were enrolled in the trial with provided consent for the study. Patients were prospectively randomized 1:1 to undergo either BPVP or TURP. Participants were blinded to the randomization scheme. All cases were assessed preoperatively and followed at 1, 3, and 6 months postoperatively by indwelling catheter time, blood loss, hospital stays, International Prostate Symptom Score (IPSS), quality of life (QOL), and Qmax.

RESULTSBPVP was significantly superior to TURP in terms of indwelling catheter time ((4.1 ± 4.1) days vs. (6.8 ± 6.8) days, P = 0.000), blood loss ((64.7 ± 103.8) ml vs. (254.7 ± 325.4) ml, P = 0.040), hospital stay ((8.7 ± 1.0) days vs. (11.7 ± 1.5) days, P = 0.000), IPSS ((4.2 ± 8.0) vs. (9.3 ± 3.7), P = 0.049), QOL ((1.5 ± 0.8) vs. (2.6 ± 1.4), P = 0.027), Qmax ((16.3 ± 5.7) ml/s vs. (12.5 ± 3.1) ml/s, P = 0.038), hemoglobin ((130.7 ± 9.4) g/L vs. ((122.1 ± 11.9) g/L, P = 0.047), Na(+) level ((138.6 ± 2.1) mmol/L vs. ((137.2 ± 2.0) mmol/L, P = 0.046) and operation time ((39.0 ± 15.5) minutes vs. ((69.3 ± 24.8) minutes, P = 0.004). And there were no statistical differences between BPVP group and TURP group in preoperatively assessment: patient's age ((70.9 ± 7.1) years vs. (71.9 ± 6.1) years, P = 0.736), IPSS ((24.6 ± 4.7) vs. (27.3 ± 5.9), P = 0.100), QOL ((5.1 ± 0.8) vs. (5.1 ± 1.0), P = 0.940), Qmax ((4.4 ± 2.7) ml/s vs. (5.3 ± 2.6) ml/s, P = 0.314), hemoglobin ((137.4 ± 8.7) g/L vs. (139.2 ± 10.4) g/L, P = 0.623), Na(+) level ((140.5 ± 1.8) mmol/L vs. (141.3 ± 1.4) mmol/L, P = 0.192) and prostate volume ((59.0 ± 17.4) ml vs. (70.1 ± 28.8) ml, P = 0.276).

CONCLUSIONSCompared with TURP, BPVP with "button-type" electrode shows superior efficacy and safety. Therefore, BPVP with "button-type" electrode represents a valuable endoscopic treatment alternative for BPH patients.
