Supplementary concept records ( SCB ) can effectively supplement and expand MeSH by forming the mapping between SCB and MeSH. Chinese herbal medicine terms indentified by MeSH Browser in SCB were analyzed in aspects of their distribution,single medicine,abstracted compositions,compound prescription,classical prescription, slef-made prescription, and use frequency,which showed the supplementary concepts in relation with Chinese herbal medicine and the existed problems. Suggestions were put forward for the use of Chinese herbal medicine terms in MeSH SCB, such as promoting their standardization, and use of standard terms when scientists publish their papers and retrieve papers from databases.

Objective To study the effect of extract of cockroach on animals with acute hepatic injury and its antiviral action in vitro. Methods The animal models with hepar injury were established by CCl4, bcg vaccine and lipopolysaccharide (LPS) . And the activities of ALT and AST in serum were measured. Serum of ducks was separated after cockroach extract was administrated. The serum was added to the culture fluid of HBV-DNA transfected hepatic cancer cells-HepG2. Results After the cockroach extract was administrated, the activities of ALT and AST in mouse serum were reduced. Both the therapeutic indexes of cockroach extract and lamivudine were larger than 2. Conclusions Cockroach extract can improve the liver function of animals with acute hepatic injury, and inhibit the secretion of ALT and AST in serum.

Objective To compare the results of three different registration methods in the kilovolt CBCT guided IMRT for nasopharyngeal cancer (NPC).Methods Total 560 CBCT images of 24 NPC patients who received kilovolt CBCT guided IMRT were analyzed off line.Three registration methods were used for alignment between CBCT and planning CT,including translational and rotational errors for bone and grey (BoneT + R,GreyT+ R),only translational errors for grey (GreyT).The registration results were analyzed by mean paired t-test respectively.Results With method BoneT+R,the translational errors on x,y and z axes were (-0.11 ± 1.35) mm,(0.40 ± 2.09) mm and (0.95 ± 1.56) mm and the rotational errors were 1.06° ±0.67°,0.01° ± 1.28° and 0.92° ± 1.00° respectively.With GreyT+R,the translational errors on x,y and z axes were (-0.02 ± 1.06) mm,(0.68 ± 1.92) mm and (0.81 ± 1.46) mm and the rotational errors were 0.85° ±0.61°,-0.05° ± 1.32° and 0.91° ±0.72° respectively.With GreyT,the translational errors on x,y and z axes were (0.58 ± 1.02),(0.52 ± 1.89) and (0.44 ± 1.43) mm.The results of compared mean t-test for different registration methods groups have significant difference (P =0.00-0.01) except for the rotational errors on y and z axes between BoneT+R and GreyT+R (P =0.05,0.62).Conclusions There have different alignment errors when different registration methods used for NPC kilovolt CBCT guided radiotherapy.If there have correct methods for rotation errors,GreyT+R registration method may be a better choice.In opposite,GreyT+R registration method would be used firstly to verify whether the rotational error ＞ 2°or 3°.If the rotational error ＞ 2°or 3°,the patient should be re-setup.If not,according to these alignment results,the GreyT method,manual method would be used to compensate the translational errors.

Objective To determine the efficacy of the double balloon catheter in ripening and dilatation of the unfavorable cervix for induction of labor .Methods A total of 332 full-term women who were underwent induction of labor with the double balloon devices were collected for retrospective analysis .Cervix was assessed before the double balloon insertion and after it was removed 12 hours later, then amniotomy alone or combined with oxytocin was performed .Cord blood gases were analyzed .Results The double balloon catheter increased Bishop score in all subgroups with a mean improvement of 2.5 ±0.7 ( P <0.05 ) .The mean insertion-deliv-ery interval was (19.07 ±4.31)h.Cesarean section was performed in 80/332 (24.1%) patients.Cord arterial pH value was 7.3 ± 0.1 .Conclusions The double balloon catheter induced significant ripening and dilatation of the unfavorable cervix .It was effective and safe.

Hepatitis B-related acute-on-chronic liver failure (ACLF) is a severe clinical syndrome characterized by jaundice, coagulopathy, ascites and hepatic encephalopathy and with a high mortality rate of 65% to 93%. It involves significant ethical issues when a randomized, double-blinded, placebo-controlled clinical study is conducted to such a serious disease. Therefore, a prospective cohort study design was utilized to explore a new treatment modality of applying integrated traditional Chinese and Western medicine.

OBJECTIVEThis study is conducted to explore new methods to perform surface biomodification of titanium implants and improve osteogenic efficiency.

METHODSAn RGD peptide and chitosan (CS) were combined by acylation reaction, forming RGD-CS. An RGD-CS/pDNA complex was subsequently prepared using a complex coacervation method and grafted on a pure titanium surface after physical and biochemical treatments were performed. The chemical structural characteristics of RGD-CS were evaluated using an infrared spectrometer and an elemental analyzer. The shape of this complex was then assessed by gel electrophoresis combined with atomic force microscopy. The grafting effect of this complex on the titanium surface was detected by EB staining.

RESULTSCS and RGD peptides were coupled by an amide bond. The RGD-CS/pDNA complex was completely composited at N/P > or = 2. Atomic force microscopy results showed that the morphology of this complex was mainly spherical. EB staining experiments showed that this complex was successfully grafted on the titanium plate.

CONCLUSIONRGD peptide-modified CS can be used as a titanium implant surface plasmid package carrier of pDNA.

Objective To explore the impacts of over-expression of microRNA-7 (miRNA-7) on the sensitivity of cis-platin in esophageal carcinoma cell line TE-1, and the possible mechanism thereof. Methods Lipofectmin 2000 method was used to transient transfect with miRNA-7 mimic into esophageal cancer cell line TE-1, which was taken as transfection group, mimic negative control was taken as transfection conrtol group. The expressions of miRNA-7 and epidermal growth factor receptor (EGFR) mRNA were detected by RT-PCR in the above two groups and normal control group. The total EGFR and EGFR in cytoplasmic and nucleus were detected with Western blot assay in transfection group and transfection control group. CCK-8 was used to detect IC50 of cisplatin in transfection group and transfection control group. The expression of EGFR was observed with immunofluorescence confocal microscope in two groups. Results The miRNA-7 expression was signifi-cantly increased in transfection group than that of transfection conrtol group and control group. The expression of EGFR mRNA was significantly reduced in transfection group (P<0.001). The total EGFR was significantly decreased in transfec-tion group than that of transfection conrtol group. The level of nuclear EGFR was significantly increased ( P<0.01),and cyto-plasm EGFR expression was significantly decreased in transfection group than that of transfection control group ( P<0.05). CCK-8 results showed that after the over expression of miRNA-7 in TE-1, the IC50 of cisplatin (48 h) increased in transfec-tion group than that of control group (P<0.01). Immunofluorescence results showed that EGFG in nuclear was higher in transfection group than that of transfection control group but its expressions reduced in cell membrane and cytoplasm. Con-clusion The over-expressed miRNA-7 in esophageal cancer cells TE-1 can reduce cisplatin sensitivity by the increased EGFR in nuclear translocation.
