Objective To study the MRI findings and pathologic characteristics of cesarean scar pregnancy during the first-trimes-ter.Methods Clinical data,MRI findings and pathologic manifestations of 23 CSP patients confirmed by surgery and pathology were analyzed retrospectively.Results On pathologic specimens by the microscope,villi and decidua tissue were found in the myometrium of all 23 cases (100%),and smooth muscle tissue in the uterus scar was incomplete in 12 cases (52.2%).The incision scars were found in the uterine lower antetheca in 21 cases,which showed low signal on T1 WI and T2 WI.A majority of the gestational sac pro-truded into intrauterine in 12 cases.The gestational sac located in the scar of lower uterine antetheca in 10 cases and in the myometri-um around the scar in 1 case.The gestational sac of 22 cases were quasi-round with the size between 1.8 cm×1.2 cm and 6.4 cm× 2.7 cm.The gestational sacs showed homogeneous low signal on T1 WI and high signal on T2 WI in 8 cases,heterogeneous high signal on T2 WI and STIR sequence in 1 5 cases,a little short T1 signal of bleeding in 9 cases,and heterogeneous high signal on DWI sequence in 3 cases.The gestational sac borders were well-defined in 18 cases and blurred in 5 cases.Among 5 cases performed by enhanced MRI,there were 3 cases which gestational sac walls were ring-shaped enhanced.Conclusion MRI findings of CSP had certain char-acteristics and could reflect the pathological characteristics of CSP.MRI had important reference value in early diagnosis of CSP and the choice of treatment.

Objective To disclose the inter-species differences among Papaver somniferum L, Papaver rhoeas L and Cannabis sativa L using AFLP analysis. MethodsThe root, stem, foliage, flower, seed of Papaver somniferum L, foliage of Papaver rhoeas L and Cannabis sativa L were collected respectively. DNA was isolated with AxyPrep Kit, and double-digested by EcoR I and Mse I, then oligonucleotide adapters were ligated. After Pre-amplification, selective amplification was performed using 6 pairs of fluorescent primer. The DNA fragments were analyzed using a CEQ 8000 DNA Fragment Analyzer. Results27 to 46, 5 to 20 and 4 to 31 pieces of amplified products were detected from Papaver somniferum L, Cannabis sativa L and Papaver rhoeas L respectively, and significant difference was observed among these three groups of products. The identical species-specific peaks were identified from root, stem, leaf, flower and seed DNA from the same Papaver somniferum L. ConclusionThe diacritical results from Papaver somniferum L, Papaver rhoeas L and Cannabis sativa L, as well as the identical results of different parts from the same plant demonstrated that AFLP analysis could be used possibly to determine the species origin of unknown plants samples.

Mastering the tools of database development is an effective way for administrative workers to improve the level of office automation. Microsoft Access 2003 is an excellent and easy-to-use development tool of applied programs. The use of it not only can lead to the development of practical application systems but is also advantageous to real-time maintenance and redevelopment. Very good results in actual work have been obtained through the use of an integrated personnel information administrative system developed by the authors with Microsoft Access 2003.

To investigate the potential role of hepatitis B virus(HBV) preS1 protein in mediating HBV adhesion to liver cell, we prepared recombinant proteins of HBV preS1 in yeast. PCR was performed to amplify the gene of HBV preS1 from the plasmid pCP10/HBV ayw subtype containing the whole fragment of HBV and the PCR product was cloned into pGEM T vector. The gene of HBV preS1 was cut from pGEM T vector and cloned into yeast expression plasmid pGBKT7, the pGBKT7 plamids containing preSl were transformed into yeast cell AH109. The yeast protein was isolated and analyzed by sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS PAGE) and Western blotting. The results showed that the presence of HBV presl proteins in yeast cells was confirmed by Western slot analysis. the molecular weight of the expressed product was about 30000 Da. The findings indicated that HBV preS1 was successfully expressed in yeast system.

BACKGROUND:Percutaneous vertebroplasty technique has become an effective means for clinical treatment of spinal osteoporotic fractures, but there is the risk of bone cement leakage.
OBJECTIVE:To explore the clinical effect of percutaneous vertebroplasty with low-dose bone cement for acute osteoporotic vertebral compression fractures.
METHODS:From September 2008 to February 2011, 32 patients with osteoporotic compression fractures were treated by percutaneous vertebroplasty. According to the dose of bone cement, the patients were divided into low dose group (2-4 mL) and routine dose group (4-6 mL). In addition, another patients who were hospitalized over the same period for acute osteoporotic compression and could not receive vertebroplasty due to urgical contraindication served as control group.
RESULTS AND CONCLUSION:The pain relief and vertebral height restoration rate of the low dose group and routine dose group were significantly better than the control group (P<0.05). The bone cement leakage rate and last fol ow-up incidence of adjacent segment vertebral fractures of the low dose group were also significantly lower than those in the routine dose group (P<0.05). Vertebroplasty with modified low dose bone cement can achieve satisfactory clinical effects, and effectively reduce the leakage of bone cement and incidence of adjacent segment secondary fractures.

AlM:To investigate the visual function in myopia and hyperopia amblyopia whose corrected visual acuity have recovered to normal.METHODS: The visual function of children ( 50 cases ) with amblyopia eyes by binocular vision correction after treatment above 0. 9 was checked. The simultaneous perception, fusion range and distance stereopsis were measured. According to the refractive condition of the children who were divided into group A ( myopia, 20 cases ) and group B ( hyperopia, 30 cases ) . The statistically difference of simultaneous perception, fusion function and stereopsis in two groups was analyzed. RESULTS: Fifteen ( 75%) and twenty - six ( 87%) children got the simultaneous perception in group A and group B respectively, and the differences between two groups were not significant (χ2=0. 454,P>0. 05). Group A had six children ( 30%) and group B had only seven children (23%) with the normal aggregative fusion range, two groups did not show any difference (χ2 =0. 565, P>0. 05). Respectively sixteen (80%),and twenty children ( 67%) had the normal divided fusion range in group A and group B, the recovery rate did not show any significant difference (χ2=0. 740, P>0. 05). Fifteen (50%) and seven ( 35%) patients acquired the far stereoscopic vision in group B and group A respectively, the recovery rate also did not show any significant difference. Normal distance stereopsis of 50 cases had 22 cases ( 44%) , and normal near stereopsis of 50 cases had 13cases ( 26%) Seven (23%) and 6 (30%) children got the normal near stereoscopic vision in group B and group A respectively, and the recovery rate did not show any significant difference (χ2=0. 195, P>0. 05;χ2=0. 295, P>0. 05).CONCLUSlON:After amblyopia treatment, although the children got the normal visual acuity, the binocular vision still can not completely normal in the short term. Myopia and hyperopia factor will not produce significant effect on binocular vision development.
