Objective: To explore the mechanisms of acupuncture in improving osteoporosis. Methods: In this study, the expression of OPG and BMP-2 proteins of femur in SAMP6 control group, SAMP6 acupuncture group, SAMP6 sham-acupuncture group and SAMR1 control group were determined by Western Blot technique. Results: Compared with SAMR1 control group, the expression of OPG and BMP-2 proteins of the femur in SAMP6 control mice decreased obviously. Acupuncture could stimulate the expression of OPG and BMP-2 and no differences were detected between the SAMR1 control group and SAMP6 acupuncture group. Conclusion: Osteoporosis observed in SAMP6 was correlated with low expression of OPG and BMP-2. After acupuncture treatment, both of them showed increased expression, it suggested that the curative effects of acupuncture on osteoporosis were partly due to stimulating skeleton formation, inducing the production of some local factors of bone metabolism and decreasing the bone turnover rate.

Objective Astrgaloside Ⅳ derivative (ASId) is one of Astragaloside Ⅳ (ASI) derivatives with higher water-solubility and may have more druggability than ASI. The present study aims at observing the effects of ASId on cardiovascular parameters in chronic heart failure in rats. Methods Using echocardiographic and haemodynamic measurements, the effects of ASId on congestive heart failure (CHF) induced by ligation of the left coronary artery in rats were investigated.ventricle (LV) pressure (dp/dt) in ASId treated groups were significantly increased. Both LV volumes in diastole and in systole were decreased significantly after ASId treatment, accompanied with a trend towards normalization of relative stress. ASId treatment also inhibited compensatory hypertrophy of depressed heart. Conclusion ASId could improve cardiac functions and inhibite compensatory hypertrophy and LV remodelling, which suggests the possibility of ASId as a new therapeutic drug for the treatment of CHF.

Objective To analyze the predictive factors of fever after percutaneous renal stone surgery,and to provide reference for clinical treatment.Methods A total of 147 patients underwent percutaneous nephrolithotomy in after operation was chosen in the Department of Urology in our hospital from January 2014 to January 2016.According to the existence of fever,patients were divided into fever (n =25,heating rate 17.0％) and control (n =122) groups.Preoperative information were collected,including age,gender,preoperative serum creatinine,stone size and shape,the involvement of calyceal number,water,urine culture results,operative time,blood loss,intraoperative perfusion volume,pyonephrosis,puncture channel length,hospitalization time and other information including intraoperative,postoperative information including fever,and postoperative renal fistula complications if there is information.SPSS 18.0 was used for statistical analysis.Results The fever group stone surface area,CT value affected calyx number,stone shape,stone properties,the involvement of calyceal number,degree of hydronephrosis,operative time,intraoperative blood loss,intraoperative perfusion,hospitalization time,and renal fistula complication rates were higher than the control group (P ＜ 0.05).There were no significant differences between two groups (P ＞0.05).The results of Logistic regression analysis found that the stone surface area (OR =5.19),stone,stone shape (OR =7.86) properties (OR =3.87),operation time (OR =5.68),intraoperative perfusion (OR =5.24),and renal fistula complications (OR =2.65) for the influence factors of fever.Conclusions The stone surface area is large,stone nature infection stones,stone shape for staghorn calculi,longer operation time,and intraoperative perfusion of large renal fistula complications were more prone to postoperative fever in postoperative.

Objective To express human chemokine-like factor 1 (CKLF1) in Drosophila S2 cells and study its function. Methods The pMT/V5-His-CKLF1 expression plasmid was constructed and transfected into Drosophila S2 cells. The positive clones were selected through PCR and RT-PCR. The culture medium was analyzed by Western blot with anti-CKLF1 polyclonal antibody. Chemotaxis and MTT assays on human peripheral blood and C2C12 cells, respectively, were then carried out with the medium. Results CKLF1 was transcribed efficiently in S2 cells. The expressed CKLF1 protein could be detected in the culture supernatant by Western blot, which showed weak chemotactic activity on both human peripheral blood neutrophils and lymphocytes as well as enhancing effect on the proliferation of C2C12 cells. Conclusion CKLF1 was expressed successfully in Drosophila S2 cells and secreted into the culture medium. The recombinant CKLF1 expressed in Drosophila cells can chemoattract leucocytes and promote the proliferation of C2C12 cells.

Objective To explore the investigation method of complicated and profound traditional Chinese herbal medicine,the potential action mechanisms of flavonoids from Scutellaria baicalensis were studied by docking calculation.Methods In total, eight flavonoids (aglycones and their glicosides) from S. baicalensis were selected as ligands.The crystalline structures of targets related to common diseases were used as the receptors for calculation. The calculations were conducted with Schr(o)dinger software package. The grading standard of selectivity was developed according to G-score between ligands and receptors. Results Twenty-six pharmacologic actions have been reported.Among all effects in literature, nine of them can be deduced from the docking calculation of aglycone. From glycosides with grade ++, 25 reported effects can be estimated by calculation. Apparently, the target selectivity of aglycones and their glycosides are different form the virtual evaluation. The virtual evaluation results of glycosides were closer to the reported effects. Conclusion Our proposed virtual evaluation method seems an effective way to investigate the complicated system of traditional Chinese herbal medicine. It suggests that aglycones may be effective as the form of glucoside in vivo, and metabolism is a very important factor for virtual evaluation.

Objective: To study the expression and localization of apoptosis-related protein TFAR19 in TF-1 cells undergoing apoptosis. Methods: Using monoclonal antibody against TFAR19, the expression level and cell localization of TFAR19 were examined by fluorescence microscope, confocal laser scan microscope(CLSM) and flow cytometry. Simultaneously, we also analyzed the relationship of TFAR19 protein with phosphatidylserine (PS) externalization and cell nuclear DNA fragmentation. Results: The level of TFAR19 proteins expressed in TF-1 cells treated with GM-CSF withdrawal was significantly increased compared with normal TF-1 cells, then translocated rapidly from cytoplasm to the nucleus of cells. Appearance of TFAR19 in the nucleus of apoptotic cells preceded the detection of PS externalization and DNA fragmentation. Conclusion: Nuclear translocation of TFAR19 protein is one of the earliest events of cell apoptotic process. These data provided a new clue to further approach to the biological function of TFAR19 and study of cell apoptosis.
