Objective: Medical therapy to prevent persistent ectopic pregnancy (PEP) after conservative laparoscopic operation was investigated. Methods:236 patients with ectopic pregnancy were divided into three groups according to the time of hospitalization. 83 cases were in group A, hyperosmolar glucose was injected into the fallopian tube lumen after laparoscopic salpingostomy. 81 cases were in group B, MTX was injected in the same way, 72 cases were in group C as control group. Serum β-HCG was tested for four times, before the operation, the first, third and a week after the operation respectively. Results:There were 6 patients of PEP in this study. One patient in group A, one patient in group B, the rest four patients in group C. The incidence of PEP was not statistically significant between group A and B( P>0. 05), while the difference was significant between group A and C ( P<0. 05). Serum β-HCG in three groups descended significantly in the first 24 hours after operation, but there were no differences among these groups. As for the descending of β-HCG in day 3 and 7, there was no difference between group A and B, but the difference was magnificent between group A and C( P < 0.05). Conclusions: Compared with the MTX, hyperosmolar glucose is an effective and safer method to prevent PEP.

In order to construct a eukaryotic co-expression plasmid containing membrane-anchored Sjcl4FABP and Sjc26GST genes and identify their expression in vitro, Sj14 and Sj26 genes were obtained by RT-PCR with total RNA of Schistosoma japonicum adult worms as the template and cloned into eukaryotic expression plasmid pVAC to construct recombinant plasmids pVAC-Sj14 and pVAC-Sj26. Then a 23 amino-acid signal peptide of human interleukin-2 (IL-2) upstream Sj14 or Sj26 gene and a membrane-anchored sequence containing 32 amino-acids of carboxyl-terminal of human placental alkaline phosphatase (PLAP) downstream were amplified by PCR as the template of plasmid pVAC-Sj14 or pVAC-Sj26 only to get two gene fragments including Sj14 gene and Sj26 gene. The two modified genes were altogether cloned into a eukaryotic co-expression plasmid pIRES, resulting in another new recombinant plasmid pIRES-Sj26-Sj14. The expression of Sj14 and Sj26 genes was detected by RT-PCR and indirect immunofluorescent assays (IFA) when the plasmid pIRES-Sj26-Sj14 was transfected into eukaryotic Hela cells. Restriction enzyme analysis, PCR and sequencing results revealed that the recombinant plasmids pVAC-Sj14, pVAC-Sj26 and plRES-Sj26-Sj14 were successfully constructed and the expression of modified Sj14 and Sj26 genes could be detected by RT-PCR and IFA. A bivalent membrane-anchored DNA vaccine encoding Sj14 and Sj26 genes was acquired and expressed proteins were proved to be mostly anchored in cellular membranes.

Objective To investigate the expression of protein interacting with Cα kinase 1 (PICK1) and its significance in colorectal adenocarcinoma.Methods The expression of PICK1 were detected by immunohistochemistry and Western blot methods in tissues of colorectal adenocarcinoma,colorectal adenoma,colorectal polyp and adjacent tissues.The correlation between PICK1 and clinical pathological data was explored.Results Immunohistochemical assay showed that the positive ratio of PICK1 protein was 72.5 ％ (74/102),and overexpressed in 31 cases (30.4 ％,31/102) with colorectal adenocarcinoma.The ratio of high expression level of PICK1 in colorectal adenoma tissues (22.2 ％,8/36) was significantly higher than that in the adjacent tissues (0,0/40) (P ＜ 0.05).The ratio of high expression level of PICK1 in colorectal polyp tissues (5.6 ％,2/36) was no statistically difference compared with that of the adjacent tissues (P ＞ 0.05).Western blot analysis revealed that the expression of PICK1 in colorectal adenocarcinoma (1.10±0.04) was significantly higher than that in the adjacent tissues (0.75±0.07) (P ＜ 0.05).The result showed significant correlation with the tumor location,the degree of differentiation,depth of invasion,TNM stages and lymph metastasis (all P ＜ 0.05).However,there is no correlation was revealed between PICK1 expression and the patients age,gender (both P ＞ 0.05).Conclusion The expression of PICK1 may be associated with the tumorgenesis,progression,invasion and metastasis of colorectal adenocarcinoma,which contributes to the prognosis of patients.

ATM: To define the causes of corneal endothelial cell damage, to investigate the preventive methods, and to observe the variety of corneal endothelial cell in glaucoma using confocal microscope.
METHODS: Totally, 143 eyes of 97 patients with different types of glaucoma, and matched normal people were 20 cases, all 40 eyes. The cell density, cell area and cell variable coefficient were measured used confocal microscope. These indicatives of every kind of glaucoma were compared.
RESULTS: The corneal endothelial cell density of normal group was 2 893. 88±255. 026/mm2 , the group of acute angle-closure glaucoma ( AACG ) was 1 674. 11±683.95/mm2 , and the group of open angle glaucoma (OAG) was 2687. 22±391. 87/mm2, the group of chronic angle-closure glaucoma (CACG) was 2706. 97±351. 27/mm2. In all index the average cell density of corneal endothelial and the average area have statistical significance ( F =62.950, 8. 795;P=0. 000), especially the group of AACG.CONCLUSION: The index of corneal endothelial cell in AACG is lower than that of normal. All index in OAG and CACG is difference with that of normal, but the difference has no statistical significance. And the dominant factor of damaged corneal endothelial is the time of intraocular hypertension.

The paper introduces an overview of Shanghai medical security system, analyzes its effectiveness and challenges, and put forward overall goals and key tasks in the future. Shanghai has formed a multiple, medical security system and basically achieved the short-term goal of medical security system establishment which was requested to put forward in national health system reform. Shanghai medical insurance system has played a positive role in promoting economic and social development and reducing the burden of medical expenses. To further implement requirements of national health system reform, Shanghai will be conducting the integration of different schemes , narrow down the gap of benefit packages, improvement of health care management and the initiatives of nursing care insurance to further improve the medical security system, and strive to cover 98% of household population and 90% resident population in 2012.

To investigate the mechanism of agarwood formation in Aquilaria sinensis induced by Lasiodiplodia theobromae, the fermentation liquor of L. theobromae was analyzed qualitatively and quantitatively by gas chromatography-mass spectrometry (GC-MS). JAs were detected in the fermentation liquor. The effect of the fermentation liquor on the abundance of sesquiterpenes in the callus of A. sinensis was analyzed by solid phase microextraction-gas chromatography-mass spectrometry (SPME-GC-MS). And the fermentation liquor stimulated alpha-guaiene, alpha-humulene and delta-guaiene biosynthesis in calli. It was inferred that L. theobromae produced JAs, which resulted in a significant increase of sesquiterpenes in A. sinensis.

The traditional fermentation engineering experiment requires a reform on the experimental con-tents and teaching pattern. According to the production process of industrial enzymes, we set up a two-week comprehensive experiment. The students designed and prepared the experiment by themselves. Moreover, the pattern of self-management was used in the process and the experiment scores included the self-assess-ment and objective assessment. It was proved that the new teaching pattern increased the study interesting of students, inspired their initiative and trained their spirits of team cooperation. The teaching effect was im-proved markedly and good ideas are also put forward to solve the possible problem.
