Objective: To compare the ocular parameters of acute angle closure glaucoma (AACG) and chronic angle closure glaucoma (CACG). Methods: Totally 106 patients with primary angle closure glaucoma were recruited: 58 patients with AACG and 48 with CACG. All patients were divided into 3 groups: AACG attack eyes group, AACG uninvolved fellow eyes group and CACG group and underwent the same ophthalmic examinations, comprising optometry, keratometry, and A-scan ultrasonography. The lens/axial length factor (LAF) and relative lens position (RLP) were calculated. Results: The AACG attack eyes had a significant shallow anterior chamber depth, thick lens, short axial length and larger LAF. hTere tended to be a reduction in the percentage of LAF>0.20 in AACG attack eyes, CACG eyes and AACG uninvolved fellow eyes, though there were no statistically signiifcant difference in all groups (P>0.05). Conclusion: The eyes with AACG attack have a more crowded anterior chamber structure compared with uninvolved fellow eyes and eyes with CACG.

Objective:To clone and express active domain of human granzyme A ( aGzmA ) and detect its biological activity.Methods:Human aGzmA gene was amplified by PCR from the full-length human granzyme A and inserted into prokaryotic ex-pression vector pET24a(+).The constructed recombinant plasmid pET24a-aGzmA was transformed to E.coli BL21(DE3) and induced with IPTG.The expressed product was identified by SDS-PAGE and Western blot.The recombinant protein was purified by the Ni2+affinity column chromatography and the enzyme activity was assayed with BLT substrate.Results: A DNA fragment of 700 bp was amplified by PCR.The recombinant plasmid pET24a-aGzmA identified by enzyme-digesting analysis and sequencing showed that aGzmA gene was inserted into vector plasmid correctly.SDS-PAGE analysis showed that there was a specific protein with a relative molecular mass of about 26 kD.Western blot analysis indicated that the protein could react with mouse anti-His monoclonal antibody specifically.The recombinant protein with high purity could be acquired from the inclusion bodies by the Ni2+ affinity column chromatography and the purified protein had good enzyme activity.Conclusion: The recombinant human granzyme A with good biological activity was prepared successfully.

Background and purpose: Mouse osteosarcoma model was widely used in osteogenic malignant tumor research, and it was helpful for studying the invasion and metastasis of the tumor cells when it was well marked in vivo. The purpose of this study was to establish mouse sarcoma cell lines (S180) that were infected with enhanced green fluorescent protein(EGFP). Methods: EGFP-S180 expressing strong EGFP fluorescence was acquired by electroblot, and supplemented with G418 (800 mg/mL), c-Myc was detected by laser scanning confocal microscopy. Meanwhile, the cancer-bearing model was established subcutaneously within the abdominal cavity. Results: EGFP-S 180 cells were cloned. There was no significantly difference between c-Myc expressions in S180 cells and those in EGFP-S180 cells (P>0.05), and between the cancer-bearing time subcutaneously and the time within abdominal cavity (P>0.05). Conclusion: According to in vitro and in vivo assay, it showed that EGFP-expressing S180 cells could be used for studying further the tumor biological behavior with fluorescence technology.

Objective　To investigate the direct antitumor effect of several surface molecules of Bifidobacterium bifidum 1101 such as whole peptidoglycan (WPG), lipoteichoic acid (LTA), and polysaccharides (PS) on human colonic adenocarcinoma cell line LoVo. Methods　MTT assay and flow cytometry (FCM) were used to evaluate the effect of Bifidobacterial surface molecules on the growth of LoVo cells. Morphological study, fluorescent polarimetry and differentiation-specific enzyme analysis were used to determine whether LTA treatment could induce the differentiation of the cells. Results　LTA but not WPG or PS significantly inhibited the proliferation of LoVo cells in a dose and time dependent manner. Cell cycle analysis by FCM revealed that LTA induced changes in cycle distribution resulting in G0/G1 phase commitment. Morphological alterations observed by light and electron microscopy indicated maturity of cytoplasm and nucleus following treatment by 50μg/ml of LTA. Membrane fluidity was also altered, and intestinal alkaline phosphatase specific for the differentiation of LoVo cells roused dramatically during culture in LTA. It was further found that LTA elevated ［Ca2+］i which resulted from Ca2+ influx instead of the release of stored calcium. Conclusion　These observations indicated that LTA was able to inhibit the growth of LoVo cells and induce the differentiation of the cells. Calcium influx may play an important role in this process.

OBJECTIVE: To comprehend the general situation of pharmaceutical services in hospitals in China.METHOD: The general situation of pharmaceutical services was investigated by questionnaire survey through mailing among a total of 600 hospitals including third-level grade A and B and second-level grade A and B hospitals and 42 pilot sites hospitals of clinical pharmacist work system selected by stratified random sampling.And the results were given a statistical analysis.RESULTS & CONCLUSIONS: A total of 281 questionnaires(46.8%) were sent back from sample hospitals and 29(69.0%) from pilot hospitals.37.1% of the hospitals developed the service of mixed dispensing for intravenous drugs,61.7% set up drug information consultation department,32.9% had monitoring software or system for rational drug use,indicating a great evolvement has been achieved in Chinese hospital pharmaceutical services.But there is still great difference in pharmaceutical care between different level and grade of hospitals.

Objective To explore the present state of clinical decision-making ability of nursing students in Sichuan Province. Methods The instrument for measuring the clinical decision-making ability of nursing students was adopted te investigate baccalaureate nursing students from four colleges and uni-versifies in Sichuan Province who had completed 10-12-month clinical practice. Results The overall mean score of clinical decision-making ability of baccalaureate nursing students in Sichuan Province was (72.86± 4.53). Among the dimensions, the scoring rate of Goal-setting Ability Dimension was the highest and that of evaluation-feedback ability dimension the lowest. In terms of the qualification rate of clinical decision-making ability, 99.52% of the students were qualified (4.82% good and 94.7% passed) and 0.48% was unqualified. Conclusions Baccalaureate nursing students in Sichuan Province have not showed a high level in clinical nursing decision-making ability and most of them are just qualified. No students have reached the level of excellence.

OBJECTIVE: To probe into the status quo of the practice of clinical pharmacy in hospitals of China.METHODS: A mailed questionnaire survey was conducted among 600 sample hospitals and 42 clinical pharmacist work system pilot hospitals based on stratified sampling regarding the status quo of the clinical pharmacy practice in China.And the results were subjected to statistical analysis.RESULTS & CONCLUSIONS: A total of 310 questionnaires were sent back,which revealed that the proportions of developing clinical pharmaceutical services including prescription evaluation,ADR monitoring,drug information consultation in hospitals at different level were high,but the proportions of developing such pharmaceutical services as medication orders' writing and drug-food interaction monitoring were low.The pilot hospitals had better clinical pharmacy services as compared with common hospitals,much as in drug therapy monitoring and individualized medication therapy.The clinical pharmacists were characterized by low quality and scanty numbers.The financial support to clinical pharmacy and the role of the clinical pharmacists remain to be intensified.

The normal arterial patterns in the left ventricle wall of 100 rabbit hearts were studied by means of postmortem coronary angiography, the clearing method and histological sections, and in comparison with that of the human heart.The intramural arterial patterns in the left ventricle of rabbit heart are similar to human heart in many ways. "Branching" type arteries (Class A vessels) supply the whole myocardium, including the subendocardial zone, while "straight" type arteries(Class B vessels)mainly supply the papillary muscle and trabeculae carneae where they form the subendocardial plexus. The arterial type in papillary muscles may be classified into segmental pattern, axial pattern and mixed pattern. The arterial distribution in the interventricular septum is without rule. The capillaries in all areas run parallel with the myocardial fibres and show cross connexions somewhere.
