AIM: The effective antisense sequences targeted VEGF mRNA with computer software would be screened and designed, and effect of them on growth K562 cells and protein expression of VEGF were studied with experiments. METHODS: Seven antisense sequences were selected and synthesized, which consisted of 18-20 deoxynucleotide acid and were modified with phosphorothioate, according to principle of low free energy of overall △G 37 Overall. Cell growth was assayed by trypan blue dye exclusion assay and level of VEGF protien in the media was determined by ELISA. RESULTS: Six of seven sequences were capable of inhibing growth of K562 cells and downregulating the VEGF protein expression significantly, compared with Scrambed control group. It was found that there was a close correlation between low level of overall △G 37 and antisense effectiveness ( r =0 887, P

Objective To investigate the efficacy of auricular plaster therapy for post-laparoscopic cholecystectomy nausea and vomiting. Methods Two hundred and forty laparoscopic cholecystectomy patients were randomly allocated to treatment and control groups, 120 cases each. Both groups received routine nursing care. In addition, the treatment group received auricular plaster therapy. The incidence of nausea and vomiting was observed in the two groups.Results The incidence of nausea and vomiting was 46.7% in the treatment group and 60.8% in the control group; there was a statistically significant difference between the two groups (P<0.05).Conclusion Auricular plaster therapy can relieve postoperative nausea and vomiting in laparoscopic cholecystectomy patients.

Biology-related disciplines in medical school of comprehensive university are cur-rently confronted with some difficulties, including unclear position and indistinguishable characteris-tics. In this paper, we proposed that biology-related disciplines in medical school of comprehensive university should center on disease research, emphasize medical feature and give full play to its tech-nical advantage thus to provide technical support for basic medicine and clinical medicine. Mean-while, sources of multiple disciplines should be effectively integrated by breaking through the limitation of discipline and administrative system. An interdisciplinary molecular medicine platform was built up for researching and teaching.

Normally, pancreatic islet?-cell mass is regulated by?-cell replication, neogenesis, apoptosis and cell size.?-cell mass in diabetic patients is conspicuously less than that in normal persons. Decline of?-cell mass is mainly caused by increased?-cell apoptosis. The change of?-cell mass is clinically becoming more and more important in regard to the progression of diabetes mellitus.

MicroRNA ( miRNA) is a family of 19 - 24 nucleotides small non - coding RNA in eukaryotic organisms , which can regulate genes at the post - transcriptional level. miRNA has been shown to be involved in a variety of cellular processes such as development, proliferation, differentiation, apoptosis etc, and is closely related to the oncogene-sis. Recent study indicates that several miRNAs play an important role in initiation and progression of hematological malignancies. miRNA expression profiling has identified signatures associated with diagnoses, prognoses and therapy of hematological malignancies. The review discusses miRNA and its biogenesis, functional mechanisms and potential role in the diagnosis , prognoses and therapy of hematological malignancies.

[Objective]To investigate the effect of atlanto-axial pedicle screw plate and fusion in treatment of upper cervical injuries. [Methods]Fifty-six cases of upper cervical spine injuries were treated with atlanto-axial pedicle screw plate and internal fixation,with total 200 screws,from March 2000 to September 2007.There were 36 males and 14 females,with an average age of 41.52 years(ranged,20~65 years).There were 23 cases of type II odontoid process fracture,12 cases of odontoid process nonunion,15 cases of transverse ligament injury.[Results]Greater occipital nerve pain occurred in 4 cases postoperatively and fully recovered after treatment 1 month later.The lateral cortical bone was penetrated by screws in 2 cases,without spinal cord or vertebral artery injury.Forty-eight cases were followed up for an average of 27.56 months(ranged,25~60 months).Bone fusion was achieved in all cases,without plate or screw broken.X-ray showed complete replacement of atlas and odontoid process of axis fracture.CT showed good position relation between screw and vertebral artery or spinal cord.According to JOA classification,excellent result was achieved in 34 cases,good in 13 cases,fair in 2 cases,poor in 1 case,with the good-to-excellent rate of 94.00%.[Conclusion]Atlanto-axial pedicle screw combined with plate fixation system is effective in treatment of upper cervical injuries.It can significantly improve the biomechanical stability of atlantoaxial joint,with high bone graft fusion rate.

Object:To find out college students' perceptions about counseling.Methods:By using a questionnaire about college students' view of counseling,875 college students of Zhejiang University from grade 1 to grade 4 were tested.Results:Most students acknowledged that counseling deals with mental issues and disorders. They were willing to help clients,and prefer counselors who are like their friends and family members.They agreed that counseling is helpful and,prefer one-hour sessions,which are free of charge.

Objective To investigate the expression of brain-type glycogen phosphorylase(GPBB)as a new biomarker in colorec-tal carcinomas,to understand its expression timing in colorectal neoplasia and its relation with the clinical pathological parameters, and to compare it with the P53 gene.Methods 40 specimens of colorectal carcinoma and 18 specimens of colorecpal neoplasia were selected.The expression of GPBB and P53 in colorectal tumor was investigated by self-made specific anti-human GPBB antibody and P53 antibody.Results The positive expression rate of GPBB in colorectal carcinoma was 80%,which was significantly higher than that in colorectal carcinoma,moreover its expression in moderate and severe atypical hyperplasia adenoma and papillary adenoma was earlier than P53 gene expression.Conclusion GPBB is a enzyme expressed in carcinoma and precancerous lesion,therefore it may be taken as early biomarker enzyme for predicting the occurrence of colorectal carcinoma.

Objective To analyze the hepatitis B virus infected patients'B-ultrasound hepatobiliary imaging and provide a refer-ence for infection prevention and diagnosis of hepatobiliary disease in the region of Shijiazhuang.Methods In three hospitals of Shi-jiazhuang,500 cases of hepatitis B virus infected patients were enrolled in the study.All patients had intact liver function test data and hepatobiliary B-ultrasound information,and their liver function test results and hepatobiliary B-ultrasound imaging test results were analyzed.Results Among 500 cases of patients with hepatitis B virus infection,22.4% patients were with alanine aminotrans-ferase (ALT)increasing,diagnosed by using B-mold ultrasonography 5.4% patients with a liver cyst,2.2% with liver abscess,8. 4% with fatty liver,1.4% with primary liver cancer percent,1.2% with secondary liver cancer,1.0% with cirrhosis.Conclusion The liver function test of patients suffering from fatty liver,cirrhosis,liver abscess shows higher proportion of ALT increasing, which suggests that in patients with hepatitis B virus infection whose liver function tests display ALT elevations should underwent B ultrasonic examination and doctors should focuse on if the patient with cirrhosis,fatty liver or liver abscess.
