Objective To study COX-2 expression in bladder transitional cell carcinoma in order to explore the relationship between the immunohistochemical staining and biological behavior of bladder cancer. Methods The expression of COX-2,Ki-67,and VEGF was examined in 50 cases of bladder transitional cell carcinoma and 10 normal bladder mucosa by means of immunohistochemical technique.Results The expression of COX-2 in BTCCs was higher than that in normal bladder mucosa.The positive rate of COX-2 was 80% in BTCCs while it was not detected in normal bladder mucosa.COX-2 was highly positively related to the grade,stage and prognosis of tumors.The expression of COX-2 in poorly differentiated,invasive or re- curring BTCCs was higher than that in well differentiated superficial or nonrecurring ones.But there was not significant difference between the solitary tumour and multiple ones.There were positive correlation both be- tween COX-2 and Ki-67 and between COX-2 and VEGF.Conclusion The high expression of COX-2 may benefit increase in bladder cancer cell proliferative activity.VEGF expression in COX-2 positive tumor was significantly higher than that in COX-2 negative tumor.

A bacterium which can effectively degrade LAS (Linear Sodium Alkylbenzenesulfonate) was isolated from washing powder manufacturing effluent and was preliminarily identified as Corynebacterium jeikeium GZ6. The bacterium can degrade LAS up to till 700 mg/L, and the optimum pH, temperature and concentration of LAS are 7.0, 30℃ and 400 mg/L, respectively. The biodegradation rate can reach 98.7% after 24 hours'cultivation in the suitable conditions. Experiments also showed that some heavy metal ions such as Hg2+ , Co2+ , Cd2+ can differently inhibit the degradation of LAS.

Nutrition support is an important part of comprehensive treatment strategy for critically ill patients. After long-term scientific research and practice, great progress has been made in theoretical cognition and clinical application. The authors summarize the metabolic charac-teristics and nutritional support strategies of critically ill patients based on their pathophysiological changes, in order to provide rational and theoretical basis for reasonable and effective nutrition support strategy in critically ill patients.

OBJECTIVETo study the surgical management of enophthalmos after severe malar maxillary complex fracture.

METHODSThe X-ray and CT examination were performed before operation to diagnose the orbital fracture and intraorbital tissue displacement. The fractured orbital rim was repositioned intraoperatively, followed by implantation of shaped titanium mesh to rebuild the orbital floor. The Medpor was inserted above the titanium mesh to correct the enophthalmos.

RESULTSFrom Sept. 2007 to Jan. 2009, 6 cases of enophthalmos after severe malar-maxillary complex fracture were treated. The enophthalmos was corrected or improved obviously in all the patients.

CONCLUSIONSThe enophthalmos after severe malar-maxillary complex fracture can be corrected or obviously improved. Shaped titanium mesh can be used to rebuild the orbital floor with the Medpor to reconstruct the intraorbital tissue volume.

Objective To investigate the application and effect of nursing quality monitoring book in ICU.Methods Quality monitoring book was used,quality control management group was established,monitoring group leader was chosen and the writing method,content as well as tracking record method of quality monitoring book were all specified.Results After the use of quality monitoring book,the nursing quality rate inspected by nursing department increased from 94.54％ to 97.41％,and the difference was statistically significant (x2 =7.788,P ＜ 0.01 ).The nursing quality rate inspected by head nurse increased from 93.59％ to 96.15％,and the difference was statistically significant ( x2 =5.270,P ＜ 0.05 ).The incidence rate of nursing adverse events decreased from 2.5％ to 0.8％,and the difference was statistically significant ( x2 =5.722,P ＜ 0.05).Conclusions The application of nursing quality monitoring book has perfected the quality feedback system,can improve management efficiency and comprehensive quality,and reduce the occurrence of nursing adverse events.

OBJECTIVETo explore methods and clinical effects of composite external fixtor in treating adult patients with unstable middle 1/3 of clavicular fractures.

METHODSFrom March 2008 to March 2011,36 patients with unstable middle 1/3 of clavicular fractures were treated with composite external fixtor. There were 24 males and 12 females, aged from 18 to 55 years old with an average of 43 years old. Twenty cases on the left side and 16 cases on the right side. Time from injury to operation was 2 to 6 days (averaged 3.5 days). According to Robinson classification, there were 7 cases with type 2A2, 18 cases with type 2B1, and 11 cases with type 2B2. No vessels and nerve damage occurred before opreation. The clinical effects were evaluated according to Neer scoring.

RESULTSAll cases were followed up from 6 to 12 months with an average of 8 months. The mean Neer score was 88.3 +/- 6.2, which included pain 31.6 +/- 3.2, functional score 25.7 +/- 2.2, range of motion score 21.1 +/- 1.7, and anatomy score 8.8 +/- 0.8. There were 22 cases in excellent, good in 13, fair in 1. Two cases occurred pin tract infection.

CONCLUSIONComposite external fixtor is an optional method in treating unstable middle 1/3 of clavicular fracture, and can obtain a good clinical effects.

In the previous study, a high-throughput screening method was established to find the antagonists of CD36. In the present study, a new compound named IMB-1680 was found using this method. The anti-atherosclerotic activities of IMB-1680 were then evaluated. Dose-dependent activities of IMB-1680 were detected by using Sf9 [hCD36] and CHO [hCD36] models. Fluorescence microscopic photography and flow cytometry were used to analyze uptake of mLDL. Foam cell test with RAW264.7 macrophages was used to examine lipid accumulation. The results showed that IMB-1680 inhibited CD36 activity with IC50 of 2.80 and 8.79 micromol x L(-1) in Sf9[hCD36] and CHO [hCD36] cells, respectively. Fluorescence microscopic photography and flow cytometry revealed that IMB-1680 could significantly reduce DiI-AcLDL uptake. Meanwhile, IMB-1680 also could reduce lipids accumulation in RAW264.7 macrophages. In all, the data indicated that IMB-1680 might be a potent effective anti-atherosclerotic leading compound.

It is held by some of the researches that the "16 collaterals" is composed of the "15 collaterals" and "the major collateral of stomach". And it is included into the textbook that Xuli, the major collateral of stomach, is the pulsation point at the cardiac region. Xuli is often explained as the empty portion of the human body by many researches. Through analysis and summarization of the related theory of the major collateral of stomach, the above mentioned opinion is discussed. And the understanding on the major collateral of stomach is deepened. As a result, it is concluded that count the major collateral of stomach into the 16 collaterals together with the 15 collaterals is inadvisable. The real pulsation point at the cardiac region locates under the left breast. And the real meaning of Xuli is "extending in all directions".
