OBJECTIVETo study the effect of some active Chinese herbal fraction on protein expression of brain tissue in ischemic mouse with proteomic technique.

METHODSIschemia-reperfusion mice were treated with baicalin, geniposide, cholic acid and concha margaritifera respectively for 3 hrs, and then their brain tissue were taken to extract the total protein. Protein expression in ischemic mouse brain was analyzed with surface-enhanced laser desorption/inionation-time of flight-mass spectra (SELDI-TOF-MS) protein-chip.

RESULTSThe four components tested had effect on 3 target proteins at 5373Da, 5707Da and 15103Da, showing the nature of multi-target and with different action on protein expression.

CONCLUSIONProtein-chip is an effective approach for exploring the pharmacological mechanism of Chinese herbal fraction.

Lynch syndrome is the most common type of genetically determined colon-cancer predisposition syndrome, accounting for 5%of all colorectal cancer (CRC) cases. This hereditary syndrome is characterized by the germline mutation of human mismatch repair genes and microsatellite instability. Recent studies have shown that Lynch syndrome and sporadic CRC differ in diagnosis and treat-ment;these results are especially relevant for the clinical management of Lynch syndrome. In this review, we reverted to the original characterization of Lynch syndrome, and the developments in its screening and diagnosis were summarized. Furthermore, the manage-ment of families with this disorder was discussed.

OBJECTIVE:To establish the quality standard of Yanyan pills.METHODS: The constituents such as Lysimachia christinae,Radix et Rhizoma Glycyrrhizae and Radix Astragali were identified qualitatively by TLC,and the content of caffeotannic acid in L.christinae was determined by HPLC.RESULTS: The TLC spots were distinctive and well-isolated.The linear range of caffeotannic acid was 0.036～0.18 ?g(r=0.999 9)with an average recovery of 100.8%(RSD=0.67%,n=6).CONCLUSION: The established standard is applicable for the quality control of Yanyan pills.

Decreasing trend has occurred in incidence of colorectal cancer in developed countries. A shift from left to right in location of colorectal cancer has been recognized,which may be associated with colonoscopy screening,aging population,diet structure modification,increased incidence of cancer and diabe-tes. Factors including sex,race and education may also play a role to some extent. Right-sided intestinal cancers have higher proportion of poor differentiation,terminal stage and mucinous component. Complications and second primary intestinal cancer are more common in right-sided intestinal cancers. Left-sided intestinal cancers tend to be well differentiated and at relatively early stage at diagnosis. With respect to molecular mecha-nism,right-sided cancers are associated with mismatch repair system,while left-sided cancers are related to p53 mutation. Based on the differences in clinicopathology and genetics,it′s implied that left-sided and right-sided intestinal cancers may belong to two different kind of disease. It′s suggested that attentions should be paid differently according to their respective characteristics in clinical practice and trials.

Objective To explore the CT manifestations of pediatric mesenechymal hamartoma of liver (MHL).Methods Clinical data of 15 cases with MHL confirmed by surgery and pathology were retrospectively analyzed.All children were performed with CT scans including plain and enhanced scans,and the imaging features were analyzed.Results All the lesions were solitary,and 9 masses located at the right lobe of liver,4 located at the left lobe,the others located at both right and left lobe.The maximum diameter of lesions was from 5 cm to 30 cm,with an average of (11.52±6.84) cm.Ten cases were cystic and solid mixed,5 cases were solid.After contrast administration,the solid component and the septa of the masses showed enhancement while no enhancement was observed in the cystic component.Two cases had the spot-like calcification.Conclusion MHL has some special characteristics in the CT scan before surgery,which should be differentiated from other cystic and solid tumors of live.Some MHLs can be diagnosed when combined with the clinical information and CT images.

OBJECTIVETo explore clinical efficacy of Yiguanjian Decoction (YD) combined Adefovir Dipivoxil Tablet (ADT) in treating HBeAg negative chronic viral hepatitis B (CVHB) active compensated liver cirrhosis (LC) patients.

METHODSTotally 68 HBeAg negative CVHB active compensated LC patients initially treated were assigned to the treatment group and the control group using random digit table, 34 in each group. Patients in the control group took ADT alone, 10 mg each time, once per day. Those in the treatment group additionally took YD, one dose per day. The therapeutic course for all was 48 weeks. Levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin (TBil) were detected once in every two weeks. Hepatitis B virus (HBV)-DNA and four items of serum liver fibrosis [procollagen type I (PCN), hyaluronidase (HA), procollagen III peptide (PCIII), laminin (LN)] were detected once per every 4 weeks. Abdominal ultrasound B was performed before and after treatment. The inner diameter of the portal vein and the size of spleen were recorded. The fibrosis degree of liver was evaluated using Fibroscan. Efficacy of Chinese medicine (CM) was evaluated between the two groups before and after treatment using CM syndrome integrals. Efficacy of Western medicine (WM) was also evaluated between the two groups using Child-Pugh grading. Results Compared with before treatment in the same group, ALT and AST levels restored to normal levels, HBV-DNA turned negative (HBV-DNA < or = 1 x 10(2)) in the two groups after 48-week treatment. Besides, levels of TBil, ALB, PCIV, HA, PCIII, and LN obviously decreased (P < 0.05, P < 0.01). Results of ultrasound B showed the inner diameter of the portal vein and the size of spleen decreased. Fibroscan results showed that the elasticity value of the liver obviously decreased (P < 0.05). Besides, post-treatment levels of PCIV, HA, PCEJ, and LN, and the elasticity value of the liver decreased more obviously in the treatment group than in the control group (P < 0.01). There was no statistical difference in post-treatment levels of ALT, AST, TBil, ALB, inner diameter of the portal vein, or the size of spleen between the two groups (P > 0.05). Compared with before treatment in the same group, scores of Chinese medical syndrome and Child-Pugh scores decreased in the two groups after treatment (P < 0.05, P < 0.01). Besides, scores of Chinese medical syndrome decreased more obviously in the treatment group than in the control group (P < 0.05). The effective rate was 8824% (30/34) in the treatment group, higher than that of the control group [67.65% (23/34)] with statistical difference (P <0.05). Conclusion Combined treatment of YD and ADT could significantly improve symptoms of CM and fibrosis degree of liver of HBeAg negative CVHB active compensated LC patients.

Objective To compare the effects of vitrification with slow-freezing on the developmental ability of day 3 cleavage stage embryos.Methods Patients who had no less than 4 high quality embryos were included in this study.These embryos were cryopreserved using the methods of vitrification or slow-freezing.In the eryopreserved embryo transfer cycles,the embryos which were cryopreserved using one of the methods were chosen randomly.The developmental ability of embryos was compared between these two groups.Results A total of 80 patients were included in this study with 160 embryos.In the group of slow-freezing,73(91%)embryos were survived and achieved 15(38%)clinical pregnancies.Among these,3 were twins and the implantation rate was 25%(18/73).In the group of vitrification,71(89%)embryos were survived and achieved 19(48%)clinical pregnancies.Among these, 9 were twins and the implantation rate was 39%(28/71),which was significantly higher than the slow- freezing group(P

The method of multiplex PCR was set up to identify two or three transgenes in one reaction such as uidA and bar; uidA and IDx5 or uidA, bar and 1Dx5 genes. Three sets of primer pairs which was specific to each of these three genes respectively were designed and synthesized. Recombinant plasmids pAHC25 and p1Dx5 harboring uidA + bar and 1Dx5 gene separately were used as template DNA in the process of optimizing an multiplex PCR reaction. The optimal annealing temperature for uidA and bar MPCR is range from 57. 1℃-62. 3℃ , for uidA and 1Dx5 is range from 60℃ to 60. 6℃ , and for uidA、bar and 1Dx5 range from 57. 0℃-58. 4℃. The amount of template for MPCR is twice as much as that for simplex PCR, while the concentration of primers is the same with simplex one. Less than 50bp MPCR products can be separated clearly by 10% non-denaturalized polyacrylamid gel electrophoresis. Fourteen transgenic wheat lines were tested by multiplex and simplex PCR respectively, which shows the same results and hence presents that MPCR is the reliable, rapid and high-effective approach to detect foreign genes from transgenic plant.
