Objective To evaluate the diagnostic value of multislice CT(MSCT)in multilocular cystic real cell carcinoma(MCRCC).Methods Imaging features of 22 patients with MCRCC proved by histopathologic examinations,these patients were underwent non-enhanced and dual-phase contrast-enhanced CT scans and evaluated CT signs.Results 22 tumors all appeared as well defined multilocular cystic mass.The cystic wall presented with irregular thicking in 14 cases and regular thicking in 8 cases.The tumors with thin coarse septum in 6 cases(the transverse diameter ≤2 mm),irregular thicking septum in 11cases(2mm ＜the transverse diameter ≤ 5 mm)and septum with nodule in 5 cases(the transverse diameter ≤ 5 mm).Cystic wall and septum enhancement were detected with dual-phase contrast-enhanced CT.Cystic ares and hemorrhagic areas and calcification were no enhanced.Calcification of cystic wall were found in 2 cases and cyst in 3 cases.Conclusion MSCT imaging appearances have typical features.It has great important value in the preoperative diagnosis of MCRCC with non-enhanced and dual-phase contrast-enhanced CT scans.

The antifungal antibiotic produced by Streptomyces luteogriseus H-103 was purified by means of macroporous adsorbent resin, and the crystal of the antibiotic with high purity was got. In this paper, the methods of purification by adsorbing of microporous adsorbent resin and detection by reversed high performance liquid chromatography with evaporative light scattering detection (HPLC-ELSD) were established. The result appeared that resin X-5 is the best adsorbent, the eluant is 50% ethanol. The antibiotic was successfully separated on Agilent~(TM)20RBA?310SB C_(18 )column (150mm?4.6mm i.d,5?m) , using a mixture of acetonitrile (A)-H_(2)O (B) as a mobile phase under gradient elution at a flow of 0.8mL/min at 30℃.0~4.0 min, V(A)∶V(B)=20∶80, 4.0~9.5min, V(A)∶V(B)=45∶55, then V(A)∶V(B)=80∶20. The drift tube temperature and the air carrier gas flow rate of the ELSD were set at 115℃ and 2.3L/min.

Objective To investigate the effect of nesfatin-1 (NSF-1) on T-type Ca2+ channel currents in adult mouse dorsal root ganglion (DRG) neurons and possible signal transduction mechanisms involved.Methods We measured the expression of melanocortin 4 receptors(MC4-R)in mouse DRG by using western blotting analysis.The whole-cell patch clamp technique was used to record the effects of NSF 1 on T-type Ca2+ channel currents in small DRG neurons and several ligands were experimented to further clarify relevant signaling pathways.Results MC4-Rs were abundantly expressed in DRG neurons.NSF-1 enhanced T-type calcium channel currents in a dose-dependent manner in small DRG neurons in mice.NSF-1 mediated increment of T-type calcium channel currents was blocked by the MC4-R antagonist HS024,phosphokinase C antagonists GF109203X,and chelerythrine chloride,while the blockade of phospohokinase A PKI 6-22 elicited no such effects.Conclusions NSF-1 can enhance T type calcium channel currents in small DRG neurons through an MC4-R-dependent PKC signaling pathway.

Objective To explore the effects of transcranial magnetic stimulation (TMS) on motor function in patients with Parkinson's disease (PD) using meta-analysis. Methods Eight comparative studies of the effects of TMS were meta-analyzed. Results The combined studies confirmed a significant difference before and after TMS treatment. Between the experimental and control groups the effect was also highly significant. Conclusion TMS may play an active role in the rehabilitation of motor function for patients with Parkinson's disease.

Objective To observe the effects of the compatibility of Radix Astragali and Radix Angelicae Sinensis in different proportion on hemodynamic and balance of Th1/Th2 cells of Qi deficiency and blood stasis rat model. Methods Qi deficiency and blood stasis rats were caused by restricted diet, forced swimming and norepinephrine subcutaneous injecting, and treated by compatibility of Radix Astragali and Radix Angelicae Sinensis in different proportion of 5∶1, 3∶1, 1∶1 and 1∶2 for 21 days. The indexes of hemorheology were detected with hemorheological analyser, and the level of IFN-γand IL-4 in serum were tested by ELISA. Results Compared with model group, the compatibility of Radix Astragali and Radix Angelicae Sinensis in proportion of 1∶1, 3∶1 and 5∶1 groups reduced the low shear blood viscosity. The spleen index of model group decreased, and compatibility of Radix Astragali and Radix Angelicae Sinensis in 5∶1 proportion group increased spleen index. The level of IL-4 increased and IFN-γ decreased in the serum of model group, the compatibility of Radix Astragali and Radix Angelicae Sinensis in proportion of 3∶1 group increased the level of IFN-γ. Astragalus angelica 5∶1 group decreased the level of IL-4 and increased the level of IFN-γ. Conclusion The compatibility of Radix Astragali and Radix Angelicae Sinensis can improve hemorheology, adjust the balance of Th1/Th2 cells of Qi deficiency and blood stasis rats. The effects were better when Radix Astragali’s dosage greater than that of Radix Angelicae Sinensis, and the group of 5∶1 proportion was the best.

A high Streptolydigin-producing strain Streptomyces lydicus AS 4.2501-L8 with genetic stability was obtained from the original strain S. lydicus AS 4.2501-P28 by mutagenesis with UV and acridine orange, followed by resistance selection. Its yield of Streptolydigin was 177.0 ?g/mL, 96.2% higher than the original strain.

OBJECTIVETo study the effect of total flavanones of Sedum sarmentosum (SSTF) on the apoptosis of rat hepatic stellate cells (HSC-T6) and its mechanism.

METHODDifferent concentrations of SSTF and HSC-T6 cells were co-cultured for different period of time. The MTT assay was used to detect the inhibitory effect of SSTF on the proliferation of HSC-T6 cells. The flow cytometry Annexin-V/PI double staining method was adopted to detect SSTF's effect on HSC-T6 cell apoptosis. Western blotting and Real-time PCR methods were applied to observe the effect on the protein and mRNA expressions of apoptosis-related cytokines Bcl-2, Bax and Caspase-3.

RESULTSSTF significantly inhibited HSC-T6 cell proliferation and induced cell apoptosis in a dose and time dependent manner. According to Western blotting result, SSTF promoted apoptosis by inhibiting Bcl-2, Bax and promoting the protein expression of Caspase-3; according to a further Real-time PCR study, Bcl-2 mRNA levels can inhibit Bcl-2 and promote Bax and Caspase-3 expressions.

CONCLUSIONSSTF has the effect of promoting the apoptosis of HSC-T6 mainly by inhibiting Bcl-2 and promoting protein and mRNA expressions of Bax and caspase-3.
