Objective To study elimination of the Micro CT projective image noise and improve the quality of the recon-structed image for the Micro CT system.Methods The forming factors of the Micro CT projective image noise were analyzed,and proposed the Micro CT projective image correction method to correct the random noise,dark field,light field,response nonuniformity and defect picture element and eliminate the random noise and the ring artifact respectively.Results Through the comparative study,it proposes a simple and practical correction method for the actual response nonuniformity which combines the corrections of light field,dark current and gain inconsistency and settles the three corrections with one circu-lation.The method can enhance the algorithm efficiency greatly and the validity of the correction protocol can be proved through experiments.Conclusion The Micro CT projective image noise is eliminated effectively and the good basis for the following work are established such as three-dimensional reconstruction.

Abstract Objective:To explore antitumor effect of NDV HN. Methods: pIRHN nucleic acid vaccin was constructed and was transfectedto Hela cells. Westem blot was used to analyssize the expression of pIRHN nucleic acid vaccine in eukarytic cell. The mode of cell death was de-tected by fluorescence microscope, gel electrophoresis and TUNEL assay. The effect of pIRHN nucleic acid vaccine on the contents of siaha acidin the Hela cell was examined. Results: pIRHN nucleic acid vaccine could be expressed in the eukarytic cell. pIRHN could induced apoptosisafter HeLa cells were transfected. The effect of antitumor responses of pIRHN was correlated with the contents of sialic acid in tumor cells. Con-clusion: The reults of our experiment will provide the theory evidence for the anti tumor mechamism of NDV.

It is well documented that altered biosynthesis of cell surface N-linked oligosaccharides is associated with the transformed cells and tumors.N-acetylglucosaminyltransferase Ⅱ(GnT-II;EC 2.4.1.143)is a medial Golgi enzyme that catalyses the incorporation of a GlcNAc residue in ?-1,2 linkage to the Man-?-1,6 arm of the N-glycan core.This is an essential step in the biosynthetic pathway leading from hybrid to complex N-glycans.Because functional GnT-Ⅱ is an prerequisite of N-Acetylglucosaminyltransferase V performance,It was speculated that GnT-Ⅱ was involved in cancer development and progression.The expression of GnT-Ⅱ in mouse breast cancer cells 67NR and 4T1 which have different behavior of metastasis was analysed using RT-PCR.The amounts of GnT-Ⅱ in the highly metastatic cell 4T1 increased to 1.53 times of the lowly metastatic cell 67NR.To determine the association of GnT-Ⅱ with tumor progression,the GnT-Ⅱ encoding gene was amplified with RT-PCR and cloned into retrovirus vector pMSCV,resulting in pMSCV-GnT-Ⅱ.The recombinant plasmid was transfected into 4T1 and the transfected cells were selected in the medium containing puromycin,which were harvested to detect the adhesion ability to fibronection and the migration potential by transwell system.The cell adhesion to fibronectin was weakened by 67% and migration potential was increased by 82%.The data indicates that GnT-Ⅱ mediates cell adhesion and migration,thus may play an important role in cancer metastasis.

Objective To explore the value of galactography in diagnosis of nipple discharge diseases. Methods Galactographies in 101 cases with nipple discharge confirmed by operation and pathology were analyzed restrospectively. Results There were breast duct ectasia in 23 cases, breast cystic hyperplasia in 12 cases , ductal inflammation in 8 cases, intraductal papilloma in 46 cases, ductal carcinoma in 9 cases, ductal tuberculosis in 1 case and normal duct in 2 cases. Conclusion The galactography is beneficial in diagnosis of the pathogenesis of galactorrhea and is of great value in differential diagnosis between benign and malignant lesions.

Objective To develop a method for treating infertile women with polycystic ovary syndrome(PCOS)by ooeyte in vitro maturation(IVM).Methods On day 3～4 of menstrual cycle,infertile women with PCOS were administrated with(100～150IU)FSH/day for 3 days.On day 8～10,when the follicle diameter reached 10～14mm and endometrium＞5mm,the immature oocytes weFe picked up and cultured in vitro for 28～31 hours.Then,ICSI and embryo transfer were performed.Results 3 clinic pregnancies were established among 12 infertile women.the pregnancy rate was 25.0%.Conclusion This research indicates that IVM is a feasible technology for the infertile women with PCOS.

Objective To explore changes of procedural memory in patients with primary insomnia(PI) and its characteristics.Methods Thirty-six PI patients and 36 controls were enrolled.The procedural memory was respectively detected with category exemplar generation and motor sequence tasks,and the declarative memory was assessed by free recall task.Results Compared with the controls,PI patients showed few correct numbers in the category exemplar generation (7.0 (6.0,8.8) vs 9.0 (9.0,11.0),Z=5.537,P＜0.01) and motor sequence task (8.0±3.3 vs 11.5 (8.6,13.8),Z=4.152,P＜ 0.01)and the phases of immediate recall (3.0 (2.3,4.0) vs 6.0 (5.0,7.0),Z =6.479,P ＜ 0.01),delayed recall (9.0 ± 2.2 vs 11.0 (10.0,12.0),Z =4.747,P ＜ 0.01) and delayed recognition (15.0 (13.0,15.0) vs 15.0 (15.0,15.0),Z=4.637,P＜0.01) of the free recall task.Furthermore,the early morning awakening group had significantly lower correct numbers in the motor sequence task,the delayed recall and recognition phases of the free recall task than the difficulty initiating and maintaining sleep groups.Conclusion The procedural and declarative memories are impaired in the PI patients,especially the early morning awakening insomniacs.

Objective To observe the role of short-term use of megestrol acetate in reducing the toxicity of chemotherapy in breast cancer and in improving the quality of life of patients, as well as its impact on neo-adjuvant chemotherapy effects. Methods The effection of adjuvant chemotherapy, toxicity, and the quality of life of 158 patients with breast cancer were investigated by a retrospective control study. The data were statistically analysized by X~2 test. Results There was no significant difference of neo-adjuvant chemotherapy effects between Megestrol acetate + CEF chemotherapy group and vitamin C + CEF chemotherapy group (Megestrol acetate + CEF chemotherapy group was 74. 84%, vitamin C + CEF chemotherapy group was 76.15) ; Megestrol acetate + CEF chemotherapy group had more modest bone marrow suppression and gas-trointestinal reactions and better food intake, weight, KPS score than vitamin C + CEF Chemotherapy group, all the differences being statistically significant (P < 0.05). Conclusion Short-term use of megestrol ace-tate can reduce the adverse effects derived from chemotherapy of breast cancer and improve the quality of life of patients with breast cancer and had no effects on the efficacy of the neo-adjuvant chemotherapy.

OBJECTIVE: To explore the clinical characteristics and prognosis of patients with idiopathic sudden sensorineural hearing loss (ISSHL) with vertigo. METHOD: By analyzing the clinical data of 271 ISSHL patients, they were divided into without vertigo group (n = 169) and vertigo group (n = 102). In vertigo group, 34 cases were patients with benign paroxysmal positional vertigo (BPPV) secondary to the ISSHL. All patients received conventional treatment. According to the types of BPPV, patients with secondary BPPV received Epley maneuver or Barbecue roll maneuver. By analyzing the results of the pure tone audiometry test and treatment outcomes of the patients, we summarized the clinical characteristics of ISSHL patients with vertigo. RESULT: The audiometric curves of ISSHL with vertigo group were mainly at high frequency. The degrees of hearing loss of these patients were severe and profound. After treatment, the improvement of hearing threshold for ISSHL with vertigo group was lower than that for ISSHL without vertigo group. What's more, the rate of recovery, success and total effective of audition for ISSHL with vertigo group was also obviously lower than that for ISSHL without vertigo group. Of all the patients with BPPV, 27 cases of posterior semicircular canal and 7 cases of lateral semicircular canal were identified. All patients with BPPV were diagnosed as the same ears as the ISSHL. CONCLUSION ISSHL with vertigo group lost hearing more severely than ISSHL without vertigo group. Also, the improvement of hearing and the effective after treatment were really poor. The symptoms of ISSHL with BPPV group improved and eased significantly than that of ISSHL without BPPV group. The major of BPPV secondary to the ISSHL occurs in the posterior semicircular canal. The canalith repositioning is an effective therapy to the secondary BPPV.
