1,2,3,4,6-penta-O-galloyl-D-glucose (PGG) is one of the main active compounds of Guizhi Fuling capsule. Molecularly imprinted polymers (MIP) have high affinity toward template molecules synthesized by molecularly imprinted technology for its specific combined sites, which can overcome the shortcoming of traditional separation methods, such as complex operation, low efficiency, using large quantity of solvent and environmental pollution. In this paper, surface molecularly imprinted polymer (SMIP) was prepared by surface imprinting with PGG as the template molecule. Its adsorption capacity was measured by the scatchard equation. The separation of PGG from Guizhi Fuling capsule at preparatived scale was achieved with molecularly imprinted polymer as stationary phase and the purity was 90.2% by HPLC. This method can be used to prepare PGG from Guizhi Fuling capsule with large capacity and is easy to operate. It provides a new method for efficient separation and purification for other natural products.

Transoral incisionless fundoplication (TIF)has been used for the treatment of gastroesophageal reflux disease (GERD)via repairing the gastroesophageal junction valve. Both the clinical report and control study confirmed that,with the prerequisite of rational selection of patients,TIF as an emerging technology can effectively cure or improve the clinical symptoms of GERD,esophagitis,and level of esophageal acid exposure. Compared with the traditional treatment,TIF is more effective,safe and having lasting effect for the rationally selected GERD patients. This article reviewed advances in study on TIF for the treatment of GERD.

OBJECTIVETo investigate the diagnostic value of FICTION (Fluorescence Immunophenotyping and Interphase Cytogenetics as a Tool for the Investigation of Neoplasms) technique, combining immunofluorescence and fluorescence in situ hybridization (FISH), to detect genetic aberrations in multiple myeloma (MM).

METHODSBone marrow samples were collected from 18 MM and 2 plasma cell leukemia (PCL) patients. Probes targeting IgH and MMSET were prepared using a Nick Translation Kit from Bacterial artificial chromosome (BAC) clones. The immunophenotyping was achieved via the CD138 tyramide signal amplification (TSA)-mediated immunofluorescence, followed by FISH with the prepared probes \[t(4;14), t(11;14), t(14;16)\] and the commercial deletion probes (13q and p53) to detect common genetic aberrations in MM.

RESULTSAll the 20 samples were assayed with the probes mentioned above, and revealed 4 cases with t(4;14), 6 with t(11;14), 1 with t(14;16), 3 with p53 deletion; and 8 with 13q deletion. The remaining 4 cases had none of the 5 aberrations.

CONCLUSIONFICTION technique facilitates the detection of genetic abnormalities of MM in situ; enhances both efficiency and sensitivity of positive detection, thus, could be used as the screening test of molecular diagnosis of MM to guide coming-up risk-adapted therapy and evaluate prognosis.
