Optical positioning system has a wide range of application in many fields. This paper presents an optical positioning method which combines linear and plane cameras. 1-D image signal of linear camera is used to get 1-D coordinates of the targets, which can be processed quickly. We can use it to assist processing the 2-D image signals of plane camera under some constraints. Linear camera can reduce the amount of position searching and calculation in coordinates extracting of targets in 2D image, and it can also help identify multiple targets. The results showed that our method could reach an accuracy of 1.608 mm, which was about one thousandth of the measurable range, and the reconstruction time for 4 targets without geometric constraints is 23.87 ms, namely 41.9 fps.

The authors first expound that Chinas WTO accession has made it extremely clear that hospital management is the key to competition. There are two aspects of the issue. One involves changing management concepts, enriching management connotations, broadening the management horizon, enhancing management levels, transforming management mentality, and readjusting management structure. The other involves the application of modern management technology. Then they discuss ways of changing hospital management from the perspective of the competition for the masses of people seeking medical service. These include: ①attracting patients with easily available service; ②heavily advertising the hospital with specific images; ③displaying quality with standardized management; ④winning the confidence of the people with reasonable pricing. Finally the authors give a detailed account of how to explore human resources, retain talented people, form optimal teams, set up rational structures and raise assessment criteria in the competition for medical talents.

Objective To examine the inhibitory effect of IL-2-PE40 on the mouse corneal allograft rejection. Methods A mouse corneal graft model was set up by using C57BL/6 mice as donors and Balb/c mice as recipients. In the treatment group, IL-2-PE40 (0.6 μg/g body weight) was intraperitoneally injected from the day of surgery every 12 h until rejection happened. In the control group, the equal volume of PS was injected intraperitoneally at the corresponding time points. The transplanted cornea was observed under slit-lamp twice a week and the transplanted corneal opacity and neovascularization were rated according to Horis grading standards. It led to the determination of rejection response. The survival of transplanted cornea was regarded to be stopped when the rejection occurred. The operated eyes were observed historically on the 10th, 15th, 25th and 35th day after the surgery, and the peripheral blood was collected for measurement of T cell subgroups and T lymphocyte colonies. Results The survival time of cornea in the treatment and control groups was (30.2±2.9) days and (15.1±2.1) days respectively. In the control group, rejection occurred on the 15th day after the surgery, CD4~+ cells started rise right after the surgery and increased most obviously on the 15th day [(63.9±4.0)%] and decreased afterwards. CD4~+ cells in the treatment group were increased slightly [(42.6±4.0)%] on the 15th day. The number of CD4~+ cells in the treatment group was obviously less than in the control group (P<0.01). No significant changes in CD8~+ cells were observed in both groups. The number of T lymphocyte colonies in the control group was increased at the beginning and dropped then. No obvious change was found in the treatment group. The number of T lymphocyte colonies in the treatment group was significantly less than in the control group (P＜0.01). Conclusion IL-2-PE40 is a highly specific immunosuppressive agent. It can delay the development of corneal graft rejection and reduce the percentage of T-helper cells significantly. It also works to weaken the forming capacity of the peripheral T lymphocyte colonies.

Objective To evaluate the quality of the randomized controlled trials (RCTs) published in two key Chineze journals on clinical nutrition.Methods The articles published in CHINESE JOURNAL OF CLIN-ICAL NUTRlTION and PARENTERAL & ENTERAL NUTRITION from 2000 to 2008 were reviewed and the RCTs were identified according to criteria of the handbook of Cochrane Collaboration.The Jadad scale was used to evalu-ate the quality of these RCTs.Results Totally 238 RCT articles were published in these two journals in this peri-od.The Jadad score of all RCT articles was 1.65±0.82.Twenty-eight articles (11.76%) were of high quality and only 5 articles (2.10%) were identified 5 points.There were some problems in the RCTs design,conduction and analyses included unclear randomization methods,poor comparison,lack of inclusion and exclusion criteria.less blinding employment,unclear withdrawals and dropouts,and improper sample size.Conclusion The design and quality control of Chinese clinical nutrition RCTs still have some problems and require further improvement.

Purpose To investigate the expression of TAZ and β-catenin in colorectal carcinoma and to analyze their correlation with the clinical pathological features of colorectal carcinoma. Methods The immunohistochemical method was used to detect the expres-sion of TAZ and β-catenin in 168 colorectal carcinoma specimens and 30 normal colorectal mucosal specimens. Results The positive rate of TAZ expression was significantly higher in colorectal carcinoma than that in normal colorectal mucosal (P<0. 01). The ectopic expression ofβ-catenin was significantly higher in colorectal carcinoma than that in normal colorectal mucosa (P<0. 01). The expres-sion of TAZ was correlated with degree of differentiation, lymph node metastasis, invasion depth and TNM stages (P<0. 05), and that of β-catenin was correlated with lymph node metastasis, invasion depth and TNM stages (P<0. 05). The positive expression of TAZ and the ectopic expression of β-catenin were significantly related to the 5-years survival rate ( P<0. 05 ) . The expression of TAZ was significantly positively correlated with the ectopic expression of β-catenin ( P<0. 01 ) . Conclusion Up-regulated expression of TAZ and ectopic expression of β-catenin may be synergistically involved in the occurrence, invasion and metastasis of colorectal carcinoma.

Objective To discuss the relativity between serum procalcitonin(PCT) level and renal impairment (RI) in critically ill patients. Methods A perspective study was performed in 60 critically ill patients. They were divided into 2 groups on the serum PCT level within 24 h: abnormal group (PCT ≥ 0.5 μg/L,38 cases) and normal group(PCT < 0.5 μg/L,22 cases). The serum creatinine (SCr) and blood urea nitrogen (BUN) were observed. Acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ ) of the patients were recorded. Calculated the sensitivity and specificity for prediction of RI as well as acute renal dysfunction (ARD). Results SCr [(188.91 ± 199.48) μmol/L]and BUN [(13.03 ±9.19)mmol/L]in abnormal group were significantly higher than those in normal group [(67.40 ± 15.35) μ mol/L and (6.91 ± 2.06) mmol/L](P< 0.01). The sensitivity of PCT forecast RI was 71.79%, and specificity was 52.38%. The sensitivity of PCT forecast ARD was 91.67% , and negative predictive value was 95.45%. Conclusion Serum PCT level has an important value for judgement of RI and ARD in critically ill patients.

Objective: To investigate the arterial baroreflex (ABR)-associated mechanism of losartan in protection of acute cerebral ischemia injury in spontaneously hypertensive rats (SHRs). Methods: Losartan (10 mg·kg -1·d-1) were administered i. g. to SHRs for 2 weeks, and the hemodynamic parameters and the baroreflex sensitivity (BRS) was determined. Then the rats were subjected to middle cerebral arterial (MCA) occlusion to establish acute cerebreal ischemia. The brain samples were obtained, sectioned and stained 24 h later; the infarction area of the brain was measured. Losartan and angiotensin II (Ang II, 100 pmol) were also microinjected into the nucleus of solitary tract (NTS) of rats, and the hemodynamic parameters and BRS were determined 24 h later. Then the rats were subjected to MCA occlusion to establish acute cerebral ischemia injury. The brain infarction area was measured 24 h after operation. Results: Compared to control rats, intragastric administration of losartan improved the ABR function and significantly decreased the infarction area (P<0.05). NTS microinjection of Ang II obviously increased the blood pressure, and decreased BRS value of rats. NTS microinjection of losartan did not change the blood pressure, and significantly improved the ABR function (P<0.05) and alleviated cerebral infarction injury (P<0.05). Conclusion: Losartan can improve the sensitivity of ABR and prevent acute cerebral infarction; NTS might be the target of losartan.
