Objective To investigate the changes of hair amino acids contents in patients with chronic kidney disease at stage 1-4 (CKD 1-4) and the intervention effect of Hushen No.Ⅱ, thus to provide modern medical evidences for the theory of kidney having its manifestations in hair. Methods One hundred cases of patients suffering from CKD 1-4 were recruited and were randomly divided into control group and treatment group, 50 cases in each group. And twenty healthy volunteers were included in normal group. The treatment group and control group received conventional treatment, and the treatment group were additionally treated with Hushen No. Ⅱ orally, the treatment lasting 12 months. And then high performance liquid chromatography was used to test the changes of hair amino acids of the three groups before and after treatment. Results Compared with the normal group, 14 kinds of amino acids in the hair of the control group and the treatment group were significantly low ( P<0.05) before treatment. After treatment, 14 kinds of amino acids in the hair of the control group and the treatment group were significantly increased ( P<0.05) as compared with those before treatment, the increase of the treatment group being superior to the control group (P<0.05). Conclusion The abnormal change of 14 kinds of amino acids in the hair of patients with abnormal renal function may contribute to the modern medical material basis of the theory of kidney having its manifestations in hair.

Objective To study the effect of dualdi butyryl cyclic AMP (dbcAMP)on the proliferation of FTC-133 cell line. Methods FTC-133 cells were normally cultured and divided into control group,dbcAMP treatment group (0.5,1.0,2.0 mmol/L). After FTC-133 cells were treated with dbcAMP (0.5,1.0,2.0 mmol/L)for 24 h or 48 h,the growth activity and growth curve was detected by MTT.Changes of the cell cycle were detected by flow cytometry.The mRNA and protein expression of Raf1 were measured by RT-qPCR and Western blotting.Results Compared with control group,the growth activity of FTC-133 cells was re-duced by different levels of dbcAMP in a dose-time dependence manner.The number of FTC-133 cells was decreased in the S phase and increased in the G2/M phase.The mRNA and protein expression of Raf1 of treatment group were both reduced compared with control group.Conclusion dbcAMP significantly reduced FTC-133 cells proliferation and promoted apoptosis,and which might be involoved by ERK MAPK signalling.

Objective To investigate the clinicopathological change in primary rhabdomyosarcoma of the ear, and its differential diagnosis with infantile rhabdomyosarcoma, primary neuro-ectodermoma, and malignant rhabdomyoma. Methods Gross and microscopic examination and immunohistochemical staining were performed in 8 cases of primary rhabdomyosarcoma of ear. Results Seven male and one female patients with mean age of 7.4 years were found. The tumor was diagnosed as embryonal rhabdomyosarcoma in 7 patients, and botryoid rhabdomyosarcoma in 1 patient. Immunostaining revealed that vimentin and myoglobin were 100% positive, desmin in 75% and actin in 82%. Conclusions Although the histological appearance of primary ear rhabdomyosarcoma does not differ from those found in other soft tissues, its clinicopathological diagnosis may be difficult in some cases, and further immunohistochemical analyses, may be necessary for a correct diagnosis. Its differential diagnosis includes infantile rhabdomyofibrosarcoma, primary neuroectodermal tumor and malignant rhabdoid tumor.

Background and purpose: For neoplasms with different sources, proteasome inhibitors can inhibit their growth and promote the cell apoptosis. Its mechanism may be associated with Bcl-2-associated athanogene 2 (BAG2). We aimed to investigate the involvement of in thyroid cancer cell death induced by proteasome inhibitors. Methods:A panel of thyroid cancer cells (ARO, FRO, KTC1, KTC2, KTC3, 8305C and 8505C) were treated with vehicle or proteasome inhibitor MG132;BAG2 mRNA and protein levels were analyzed using quantitative real-time polymerase chain reaction (qRT-PCR) and Western blot, respectively. Results:MTT results indicated that FRO and KTC2 cell lines were the most sensitive to proteasome inhibitors. MG132 induced BAG2 mRNA and protein expression in the panel of thyroid cancer cells with various degree (P<0.01), for FRO and KTC2 cell line, the BAG2 mRNA level was increased in 20 to 25 times, meanwhile the protein expression level also increased signiifcantly;Sensitive FRO cells demonstrated quicker induction of BAG2 compared with insensitive ARO cells. Moreover, the extents of BAG2 induction in FRO cells were higher than that in ARO cells. Conclusion: BAG2 is a novel molecule induced by proteasome inhibitor, which might function as a proapoptotic molecule in thyroid cancer cell death mediated by proteasome inhibitor.

Objective To evaluate Doppler spectrum of ductus venosus(DV) in selective intrauterine growth restricted(sIUGR) pregnancies.Methods Thirty-five sIUGR pregnancies and 35 normal single pregnancies with same gestational week were enrolled,there were 10 sIUGR Ⅰ,13 sIUGR Ⅱ and 12 sIUGR Ⅲ in sIUGR.Spectrum of ductus venosus,such as DV S wave,DV D wave,DV A wave,DV PI,DV PLI and S/A were assessed.Results ① There was no significantly difference in spectrum of ductus venosus between bigger of sIUGR,smaller of sIUGR Ⅰ with normal fetus (all P ＞0.05).② Compared with normal fetus,DV-PI,DV-PLI and S/A were significant higher in smaller of sIUGR Ⅱ and sIUGR Ⅲ (P ＜0.05);DV-S wave,and DV-D wave showed no significantly difference in smaller of sIUGR Ⅱ and sIUGRⅢ (P ＞0.05).Conclusions Spectrum of ductus venosus in bigger of sIUGR and smaller of sIUGR Ⅰ are mainly normal,and nearly in good condition in utero,inversely,abnormal spectrum of ductus venosus commonly exists in smaller of sIUGR Ⅱ and sIUGR Ⅲ,and supervision should be done carefully in these group.

AIM: To investigate the molecular mechanism of microRNA-21 (miR-21) in the regulation of Schwann cell proliferation following nerve injury.METHODS:The expression of miR-2l was detected by real-time PCR. Synthetic miR-21 mimic and its control were transfected into rat Schwann cells.CCK-8 assay was performed to evaluate the influence of miR-21 on the proliferation of Schwann cells.The cell cycle distribution was determined by flow cytometry. The expression of transforming growth factorβ-induced protein ( TGFBI) and cyclin D1 were detected by Western blotting. RESULTS:The expression of miR-21 in model group was 7.87 ±0.75 and 7.75 ±0.80 times higher than that in sham operation group and blank group respectively.After transfected with miR-21 mimic, the expression of miR-21 in experimen-tal group was 2.21 ±0.14 and 2.29 ±0.21 times higher than that in negative control group and blank group respectively. Moreover, the A450 value of CCK-8 assay in experimental group at 48 h was higher than that in negative control group and blank group.The proliferation index in experimental group was higher than that in negative control group and blank group. At the same time, the expression of TGFBI obviously decreased and the cyclin D1 increased in the Schwann cells 48 h after transfection with miR-21.CONCLUSION:miR-21 promotes the proliferation activity of Schwann cells by down-regulating TGFBI expression.
