AIM To study the protective effects of Jingqi Capsules (Cordycps Militaris,Rehmanniae Radix Praeparata,Lycii Fructus,) on the damage to rat reproductive system induced by cyclophosphamide.METHODS After low and high dose groups of Jingqi Capsules and positive group were administered for two weeks in advance,cyclophosphamide [25 mg/(kg · d)] modeling was conducted consecutively by intraperitoneal injection for five days except the normal group,while the treatment groups were administered consecutively.All the rats were executed the day after the end of the modeling.Serum testosterone content was measured by radioimmunoassay;body weight,testis,epididymis and prostate of rats were weighed and organ coefficient was calculated;morphology of testis was observed by HE;sperm count and sperm motility were detected by CASA;apoptosis of cells was observed by TUNEL.RESULTS Compared with the model group,each dose group of Jingqi Capsules increased in the level of serum testosterone and organ coefficient of testis,epididymis and prostate.The damage to seminiferous epithelium relieved and the number of all spermatogenic cells increased.Sperm count and sperm motility increased.Decrease in apoptosis of cells was demonstrated by TUNEL.CONCLUSION Jingqi Capsules has protective effects on damage to rat reproductive system induced by cyclophosphamide.

Objective:To explore and analyze the points-selection rules in acupuncture treatment of mammary gland hyperplasia (MGH) by data mining and statistical method. Methods:Clinical literatures about the treatment of MGH with acupuncture published in the recent 16 years were retrieved from Chinese Journal Full-text Database (CJFD) and established into a database by Excel. The SPSS 20 version software and Clementine 12.0 version software were adopted to analyze the frequency and association rules of points-selection in the treatment of MGH with acupuncture. Results:The top 3 points used most frequently in acupuncture treatment of MGH were Danzhong (CV 17), Taichong (LR 3) and Zusanli (ST 36); points from the Stomach Meridian of Foot Yangming and Liver Meridian of Foot Jueyin were most commonly used; the commonly selected points were predominantly distributed in thoracic and abdominal regions and lower limbs; emphasis on the combination use of local and distal points; of the specific points, the five Shu-Transmitting points were mostly used; association analysis showed that the associations among Taichong (LR 3), Danzhong (CV 17) and Zusanli (ST 36) were the most significant. Conclusion: The data mining results substantially accord with the general rules of acupuncture-moxibustion theories in traditional Chinese medicine, able to reflect the points-selection principles and features in acupuncture treatment of MGH and provide evidence for the points selection in the treatment of MGH in acupuncture clinic.

· AIM: To report a rare case of mesenchymalchondrosarcoma in the orbit and to explore its clinicmanifestations, pathologic characters, management andprognosis. · METHODS: We report a case of mesenchymalchondrosarcoma of the orbit. The clinical materials,including ophthalmological examination, computed tomo-graphy scan of the orbit, histopathology and immunohis-tochemistry of the biopsy specimen was reported, and itspertinent literatures were reviewed.· RESULTS: A 36-year-old female was seen with proptosisand decreased vision. Histopathology demonstrated anadmixture of undifferentiated mesenchymal cells andislands of mature hyaline cartilage. Immunohistochemicalstudies revealed positivity for vimentin and S-100, whichwas consistent with the diagnosis of mesenchymalchondrosarcoma.· CONCLUSION: Mesenchymal chondrosarcoma in theorbit is extremely rare malignant tumor. Multi-modalitytreatments (surgery, chemotherapy and radiotherapy)may lead to long-term survival.

The aim of this study was to explore the synergistic effect of arsenic trioxide and bortezomib on apoptosis of Raji cell line. The cells were treated with arsenic trioxide, bortezomib, low-dose arsenic trioxide combined with bortezomib, respectively. The cell viability and proliferative curve were estimated by trypan blue dye exclusion. The cell apoptosis and cell cycle status were analyzed by flow cytometry. The apoptosis related elements such as caspase-3, BCL-2, BAX, JNK2 and IkappaB-alpha, were measured with Western blot. The results showed that compared with cells treated with mentioned above drugs alone, the proliferative potential of cells in combination group was significantly inhibited (p < 0.01), and apoptosis rate markedly increased (p = 0.001), while obvious cell cycle arrest was not observed. On the protein level, the expression of Caspase-3, BAX and IkappaB-alpha increased, while the expression of BCL-2, and JNK2 decreased. It is concluded that low-dose arsenic trioxide combined with bortezomib synergistically induced apoptosis in Raji cell line which may be mediated by inhibiting NK-kappaB and JNK2 signaling.

OBJECTIVETo study the expression profile of microRNAs (miRNAs) in peripheral T cell lymphoma, not otherwise specified (PTCL-NOS) and to explore the underlying molecular characteristics.

METHODSTwenty-one cases of PTCL-NOS were enrolled into the study. The tumor presented either as nodal (15/21) or extranodal (6/21) disease. TaqMan low density array was used to assess the expression level of 754 miRNAs in six cases of PTCL-NOS and three control cases of reactive lymphoid hyperplasia. Prediction of target genes for significant and differential expression of miRNAs was carried out using Targetscan and miRanda software. Bioinformatics tools were employed for GO-Analysis and Pathway-Analysis of target genes. The expression patterns of the three miRNAs were further analyzed in the remaining 15 cases of PTCL-NOS and 10 cases of reactive lymphoid hyperplasia, using single tube Taqman miRNA assays.

RESULTSEight miRNAs showed statistically significant difference in expression between PTCL-NOS and reactive lymphoid hyperplasia. miR-886-3p, miR-511, miR-1291, miR-572, miR-27a-3p, miR-25-3p and miR-886-5p were significantly overexpressed in PTCL-NOS while miR-182-5p was significantly underexpressed (P < 0.05). Target gene prediction showed that 1646 candidate genes involved in the pathogenesis and progression of PTCL-NOS. Further GO and Pathway-Analyses found that these genes significantly focused on 63 GO terms and 61 pathways. The results of three miRNA qRT-PCR confirmed that miR-572 and miR-1291 expression in PTCL-NOS had statistical significance.

CONCLUSIONSEight miRNAs are aberrantly expressed in PTCL-NOS, which may be involved in molecular regulation during the development of PTCL-NOS. The underlying mechanism is also related to a number of target genes and signaling pathways.

OBJECTIVETo investigate the role and significance of Wnt/beta-catenin signaling pathway regulating GSK-3beta, STAT3, Smad3 and TERT in hepatocellular carcinoma (HCC).

METHODSThe HCC cell line HepG2 was transfected with small interfering RNA (siRNA) directed against beta-catenin. Proteins were extracted and the expressions of beta-catenin, GSK-3beta, p-GSK-3beta, STAT3, Smad3 and TERT were detected by Western blot at 72 h and 96 h respectively after transfection.

RESULTSbeta-catenin expression was inhibited at both time points and the expression at 96 h was higher than that at 72 h (t = 4.43, P < 0.05). Interestingly, GSK-3beta and p-GSK-3beta expressions increased gradually at 72 and 96 h (tGSK-3beta= 4.98, tp-GSK-3beta= 29.83, P < 0.05) respectively, and STAT3 expression showed no alteration after transfection (F = 0.49, P > 0.05). Smad3 expression was increased at 72 h (t = 10.67, P < 0.05) and decreased to normal at 96 h (t = 1.26, P < 0.05), while TERT expression decreased at 72 h (t = 4.18, P is less than 0.05) and increased to normal at 96 h (t = 1.26, P > 0.05).

CONCLUSIONSWnt/beta-catenin signaling pathway is related to the expressions of GSK-3beta, Smad3 and TERT, but perhaps not related to STAT3 protein expression in HCC. It suggested that Wnt/beta-catenin signaling pathway might participate in HCC genesis and development through regulating the above three factors.
