Objective To study the influence of electro-acupuncture(EA)at Zusanli points(足三里穴) on the apoptosis of thymocytes in rats with abdominal infection and its mechanism.Methods A total of 40 Sprague-Dawley(SD)rats were randomly divided into four groups,including normal control group,model group,non-acupoint group and Zusanli group.The abdominal infection model of rat was made by cecal ligation and puncture(CLP).After abdominal cavity infection for 36 hours,the apoptosis of thymocytes was observed under electron microscope and light microscope,and the apoptosis ratio of thymocytes was determined by Annexin V-PI method with flow cytometry technique.The content of Bcl-2 protein of thymocytes and concentration of corticosterone in plasma were determined.Results Abdominal infection resulted from CLP could significantly increase the apoptosis of thymocytes and lead to the typical histopathological changes of apoptosis of thymocytes under electron microscope and light microscope.Apoptosis ratios of thyrnocytes in model group[(44.7?3.3)%],non-acupoint group[(42.7?3.0)%]and Zusanli group[(32.6?3.3)%] were significantly higher than the ratio in the control group[(21.2?2.3)%,all P0.05).Abdominal infection resulted from CLP also could reduce the content of Bcl-2 protein of thymocytes.The content of Bcl-2 protein of thymocytes in model group(71.2?5.6),non-acupoint group(73.5?5.9)and Zusanli group(82.4?6.8) were significantly lower than normal control group(95.3?6.3,all P

Objective To build a foundation for determination of C reaction protein,C reaction protein was expressed and purified,and the immune reactivity of the purified protein was identified.Methods The CRP cDNA was amplified by RT-PCR from human liver cDNA library and inserted into expression vector pCRTT/NT.The recombined plasmid CRP-pCRTT/NT which expressed the fusion protein of CRP was then transferred into lysogenic host strain E coli.BL21 (DE3).The target protein was identified using SDS- polyacrylamide gel electrophoresis (SDS-PAGE).Affinity chromatography was used for protein purification.The immune reactivity of purified CRP was identified by Western blot using anti-CRP specific antibody.Results Recombiant human CRP was expressed in inclusion bodies of E.coli with a six histamine tag.The purify of recombinant protein was detected by SDS-PAGE as a single band at 30 000 and was identified by Western blot.Conclusions A plasmid expressed CRP protein is constructed and the purification system of CRP protein is established.The immune reactivity of the purified protein is identified by Western blot,which makes a good base for the preparation of CRP test kit.

OBJECTIVESTo screen differential proteins in serum from hepatocellular carcinoma (HCC) patients by Proteomic Technology and to purify and identify them.

METHODSSurface enhanced laser desorption Ionization time of flight-mass spectrum (SELDI-TOF-MS) was employed to screen differential proteins in serum from 33 HCC patients and 33 control cases, and then to purify and identify them using isoelectric precipitation, Tricine sodium dodecyl sulphate polyacrylamide gel electrophoresis (Tricine-SDS-PAGE) and high performance liquid chromatography tandem Mass Spectrum (HPLC-MS).

RESULTS65 protein peaks in the range of relative molecular weight from 2,000 to 10,000 were found significant difference (P less than 0.05) between the patient group and control group. Based on these differential protein peaks, diagnostic model for HCC detection was established and its sensitivity and specificity were 100% and 96.97% respectively. Proteins with 8,706.5 and 8,579.2 relative molecular weights (the t value was 2.562 and 2.783 respectively, and P value was 0.013 and 0.015 respectively) out of the 65 differential proteins were purified and identified, and then recognized as Apolipoprotein AII (Apo AII).

CONCLUSIONApo AII is probably a differential protein of HCC and maybe related to the pathogenesis of HCC.

To compare the effects of inoculated or non-inoculated with arbuscular mycorrhizal (AM) fungi on the steroidal saponin component in root of Paris polyphylla var. yunnanensis. By pot experiments, steroid saponin component in root of P. polyphylla var. yunnanensis was determined and compared by HPLC. The results showed there was difference in the effects of different AM fungal on the secondary metabolite steroid saponin in P. polyphylla var. yunnanensis. After elicitors treatment, AM fungal did not change the chemical backgrounds of P. polyphylla var. yunnanensis, but can improve partly the content of chemical compositions in roots. In conclusion, there was selectivity between AM fungal and P. polyphylla var. yunnanensis. Glomus intraradices was the most appropriate strain for inoculation P. polyphylla var. yunnanensis.

Recently, we treated a patient with pulmonary vein sarcoma. The patient was a 41-year-old woman, had cough, short of breath and apsychia, with obvious jugular venous distention, rales in both lungs and a diastolic murmur at the apex. CT and Echo revealed a tumor in the left atrium. She received an emergency surgery to remove the mass in the heart. The pathological diagnosis demonstrated it as leiomyosarcoma. Though the patient accepted radiotherapy and chemotherapy, she still died of recurrence and metastasis of the sarcoma 10 months after operation.

Osteosarcoma is suggested to be caused by genetic and molecular alterations that disrupt osteoblast differentiation. Recent studies have reported that transmembrane protein 119 (TMEM119) contributes to osteoblast differentiation and bone development. However, the level of TMEM119 expression and its roles in osteosarcoma have not yet been elucidated. In the present study, TMEM119 mRNA and protein expression was found to be up-regulated in osteosarcoma compared with normal bone cyst tissues. The level of TMEM119 protein expression was strongly associated with tumor size, clinical stage, distant metastasis and overall survival time. Moreover, gene set enrichment analysis (GSEA) of the Gene Expression Omnibus (GEO) GSE42352 dataset revealed TMEM119 expression in osteosarcoma tissues to be positively correlated with cell cycle, apoptosis, metastasis and TGF-β signaling. We then knocked down TMEM119 expression in U2OS and MG63 cells using small interfering RNA, which revealed that downregulation of TMEM119 could inhibit the proliferation of osteosarcoma cells by inducing cell cycle arrest in G0/G1 phase and apoptosis. We also found that TMEM119 knockdown significantly inhibited cell migration and invasion, and decreased the expression of TGF-β pathway-related factors (BMP2, BMP7 and TGF-β). TGF-β application rescued the inhibitory effects of TMEM119 knockdown on osteosarcoma cell migration and invasion. Further in vitro experiments with a TGF-β inhibitor (SB431542) or BMP inhibitor (dorsomorphin) suggested that TMEM119 significantly promotes cell migration and invasion, partly through TGF-β/BMP signaling. In conclusion, our data support the notion that TMEM119 contributes to the proliferation, migration and invasion of osteosarcoma cells, and functions as an oncogene in osteosarcoma.
