OBJECTIVETo evaluate the effect of the platelet-derived growth factor-BB (PDGF-BB) on the phenotypic transformation of corpus cavernosum smooth muscle cells (CCSMC) in SD rats.

METHODSCCSMCs were primarily cultured in the modified tissue sticking medium and subjected to immunofluorescence assay. The cells were divided into a blank control and four PDGF-BB groups, the latter exposed to 5, 10, 20, and 40 ng/ml of PDGF-BB, respectively, for 24 hours, and the cells in the 20 ng/ml PDGF-BB group treated for 24, 48, and 72 hours. The the relative expressions of α-SMA, SMMHC, calponin, and OPN mRNA were determined by real-time fluorescence quantitative RT-PCR (qRT-PCR).

RESULTSThe α-SMA positive rate of the CCSMCs was over 95%. Compared with the blank control group, the expression levels of α-SMA, SMMHC, and calponin mRNA were significantly decreased (P < 0.05) while that of OPN mRNA remarkably increased (P < 0.05) in the PDGF-BB groups. The 20 ng/ml PDGF-BB group also showed significantly downregulated expressions of α-SMA, SMMHC, and calponin mRNA (P < 0.05) and upregulated expression of OPN mRNA (P < 0.05) at 24, 48, and 72 hours.

CONCLUSIONPDGF-BB can induce the transformation of the phenotype of CCSMCs in SD rats from the contractile to the synthetic type.

Four hundred and sixty five randomly selected clones from a cDNA library of Blattella germanica were partially sequenced and searched using BLAST as a means of analyzing the transcribed sequences of its genome. A total of 363 expressed sequence tags (ESTs) were generated from 465 clones after editing and trimming the vector and ambiguous sequences. About 42% (154/363) of these clones showed significant homology with other data base registered genes. These new B. germanica genes constituted a broad range of transcripts distributed among ribosomal proteins, energy metabolism, allergens, proteases, protease inhibitors, enzymes, translation, cell signaling pathways, and proteins of unknown function. Eighty clones were not well-matched by database searches, and these represent new B. germanica-specific ESTs. Some genes which drew our attention are discussed. The information obtained increases our understanding of the B. germanica genome.

OBJECTIVE To investigated the regulatory effect of paeoniflorin-6'-O-benzene sulfonate (CP-25) on B cell activating factor (BAFF)/BAFF receptor-nuclear factor of kappa B (NF-κB) signaling in B cell of collagen induced-arthritis (CIA) mice. METHODS Mice CIA was induced by injection of typeⅡcollagen (CⅡ). The arthritis index (AI) and swollen joint count (SJC) were assessed, and histopathology of spleen and joints were observed. The percentage of B cells subsets, BAFF receptor expressions were analyzed by flow cytometry. BAFF and immunoglobulin (Ig) levels were measured by protein antibody array. The expressions of TRAF2, MKK3, MKK6, p-P38, and p-NF-κB65 in NF-κB signaling mediated by BAFF were analyzed by western blot. RESULTS CP-25 decreased AI and SJC, restored abnormal weights, reduced thymus index and spleen index, inhibited T/B cells proliferation, alleviated the histopathology of spleen and joints in CIA mice. CP-25 also reduced high levels of serum BAFF and immunoglobulin, decreased CD19+B cells, CD19+CD27+B cells, and CD19-CD27+CD138+ plasma cells, inhibited BAFFR and TACI expressions, decreased the expressions of TRAF2, MKK3, MKK6, p-P38, and p-NF-κB65. Compared with biological agents etanercept and rituximab, CP-25 restored high T cells proliferation and percentages of B subsets to normal level, and recovered the high levels of IgA, IgD, IgG1, IgG2a and high expressions molecules in NF- κB signaling to normal levels. The action intensity of rituximab and etanercept was more strong than CP- 25. The inhibitor effects of rituximab and etanercept on AI and SJC, thymus index, proliferation of T cells and B cells subsets were strong, and down-regulated the indexes to under normal levels. CONCLUSION CP-25 might be a promising anti- inflammatory immune and regulation drug, which alleviated CIA and regulated the functions of B cells through BAFF/BAFF receptor-NF-κB signaling.

OBJECTIVETo compare the clinical efficacy of 3 different treatment programs for oligospermia patients of Shen-essence deficiency syndrome (SEDS).

METHODSTotally 450 male patients were randomly assigned to 3 groups, i.e., the treatment group, the control group 1, and the control group 2, 150 in each group. Patients in the treatment group were treated by Bushen Yijing Decoction (BYD), tamoxifen tablet (TT), Licorzine Capsule (LC), and Vitamin E Soft Capsule (VESC). Those in the control group 1 were treated by BYD, LC, and VESC. Those in the control group 2 were treated by TT, LC, and VESC. All patients were treated for 3 months. Their pregnant rates were compared. Clinical efficacies of each Chinese medical symptom and sperm parameters [sperm density, grade a sperm motility rate, grade (a + b) sperm motility rate, grade (a + b + c) sperm motility rate, and normal sperm morphology rate] were compared before and after treatment.

RESULTSAt 3 months after treatment 61 patients were pregnant in the treatment group, 36 patients were pregnant in the control group 1, and 30 patients were pregnant in the control group 2. The differences in the sperm density, grade a sperm motility rate, and grade (a + b) sperm motility rate, and grade (a + b + c) sperm motility rate between before and after treatment were significantly higher in the treatment group than in the control group 1 and the control group 2 (P < 0.01). The difference in the normal sperm morphology rate between before and after treatment was obviously higher in the treatment group and the control group 1 than in the control group 2 (P < 0.01). Better results were obtained in the treatment group and the control group 1 in improving the sexual apathy, soreness and weakness of waist and knees, impotence, premature ejaculation, seminal emission, dizziness, tinnitus, forgetfulness, alopecia, when compared with the control group 2 (P < 0.01, P < 0.05). There was no statistical difference in the total effective rate of improving Chinese medical symptoms between the treatment group and the control group 1 (P > 0.05).

CONCLUSIONBYD combined with TT, LC, and VESC could significantly improve sperm qualities and clinical Chinese medical symptoms of oligospermia patients of SEDS.

Objective To explore the relationship between gene polymorphism of neuropeptide Y (NPY) promoter and cerebral stroke subtypes according to TOAST (Trail of ORG 10172 in Acute Stroke Treatment) criteria in Chinese Han population. Methods The gene polymorphisms at position of-399T/C, -883Tgins/del and -602G/T in NPY promoter were detected by PCR method and gene sequencing in 190 cases of large-artery atherosclerosis stroke (LAA), 260 cases of small-artery occlusion (SAO), 60 cases of cardioembolism stroke (CE), 29 cases of stroke of other demonstrated etiology (ODE),10 cases of stroke of other undemonstrated etiology (UE) and 423 healthy control subjects. The PCR products were directly sequenced. Multivariate logistic regression was performed to analyze the relationship between gene polymorphism of NPY promoter and cerebral stroke subtypes according to TOAST by removing the confounding variables. Results Significant differences in the frequency of genotype CC and allele C at position of-399T/C were noted between the patients with SAO and controls (P=0.046, P=0.010). Compared with the control group, patients with LAA and SAO were more likely having high level of uric acid, hypertension, diabetes mellitus and heard disease (P＜0.05). No statistic differences in the frequency of genotype DD and allele D at position of-883Tgins/del were noted between patients with SAO and controls (P=0.0605, P=0.155). Gene polymorphisms of-399T/C,-883Tgins/del and -602G/T did not associate with an increased risk of having LAA, CE, ODE and UE.Conclusions The gene polymorphisms of promoter in position of-399T/C gene maybe associate with the happening of SAO; allele C at the position of-399T/C may raise the risk of the disease. There is no relationship between the gene polymorphisms of promoter at position of-399T/C, -883Tgins/del, -602G/T and the patients with LAA, CE, ODE and UE. High level of uric acid, hypertension, diabetes mellitus and heard disease history are the risk factors of LAA and SAO.
