OBJECTIVE:To evaluate the effect of temozolomide(TMZ)in combination with dexamethasone(DXM)on the proliferation of human gliocytoma U251 cells in vitro.METHODS:Human U251 cells were assigned to 1 of the 3 groups: TMZ(10,25,50,100,200,400?mol?L~(-1),respectively)alone or in combination with 40?mol?L~(-1)DXM(TMZ+DXM group)or control group(none drug).After treatment for 72 hours,the cell morphology,cell inhibition ratio,cell cycle and the apoptotic rate were detected.RESULTS:When TMZ concentration was greater than 100?mol?L~(-1)the cell inhibition ratio was higher in TMZ-treated group than in TMZ+DXM-treated group(P

The event of “diagnosing mental disorder but actually not” violates patients′right of informed con-sent and refused to health , showing some problems of “diagnosing mental disorder but actually not” and mandatory admission process and psychiatric judicial authentication , and also have some ethical problems .Therefore, relevant departments should perfect the laws and regulation , establish a hospitalized psychiatric patients appeal , the appeal channels , at the same time , physicians should follow a correct understanding , respect patients rights , disinterest-ed, the ethical principles of self -supervision and also use constraints should be regulated .

OBJECTIVE To analyze predisposing factors and investigate the measures to fungemia.METHODS The clinical features,therapy and outcome of 17 patients with fungemia which happened from 1995 to 2004 were(retrospectively) reviewed.RESULTS The morbidity of fungemia was 5.52% in all septicemia in our hospital.Candida(tropicalis) and C.albicans were the major fungal species.There were 6 patients found cultured fungi on local(foci).Tracheotomy and mechanical ventilation (47.06%),indwelling urinary catheter(41.18%),indwelling(central) venous catheter and drainage tube(41.18%),persisted use of broad spectrum antibiotic(76.47%),(chemical) therapy(17.65%),admission to ICU(29.41%),and neutropenia(29.41%) might be the predisposing(factors).The mortality of fungemia was 70.59%.CONCLUSIONS The morbidity of non-C.albicans fungemia is(increasing),preemptic therapy should be begun earlier.Higher dose of fluconazole may be recommended in clinical usage.

Objective To develop ICU digital system for over-all monitoring and remote monitoring.Methods The programming and design was performed according to the principles of"taking patients as center,clinic as basis,utility as goal,service as aim".Results ICU digital system was composed of digital medical instruments and their clinical Gateway,intensive care information system,bedside integrated clinical information terminals,nurse workstation integrated clinical information terminals,serious patients visit system,little smart local communication system,consultation demonstration teaching system and personal digital assistant clinical information terminal system.Conclusion As one of the important symbols of modern hospital,the ICU digital system integrates the vital signs information of every patient in ICU and implement seamless connection with CIS,LIS,PACS,HIS.The construction of ICU digital system will accelerate the digital hospital's development.

AIM: To investigate the effect of urokinase plasminogen activator (uPA) on metastasis inhibition of gastric cancer SGC7901cells induced by parthenolide. METHODS: The changes of SGC7901 cells reproductive activity were analyzed by MTT. Light microscope was used to observe the cell morphological changes. The effects of parthenolide on migration and invasion capacity of SGC7901 cells were determined by using matrigel and transwell system. The expression of uPA was detected by Western blot and RT-PCR assays. RESULTS: Parthenolide inhibited the proliferation of SGC7901 cells in a time-and concentration -dependent manner ranging from 100 to 200 ?mol/L. Light microscopy showed the suppressing effect on growth of SGC7901 cells. After exposed to parthenolide, the migration and invasion capacity of SGC7901 cells were significantly decreased, the number of cells gradually decreased through the basement membrance. The Western blot assay showed that the expression of uPA protein declined gradually after exposed to parthenolide for various period of time. CONCLUSION: Parthenolide can inhibit the growth and metastasis activity of SGC7901 cells, and uPA played an important role in the latter process.

Objective:To observe the curative effect of traditional Chinese medicine on non-alcoholic fatty liver patients and CTN(computerized tomographynumber)of liver,than to appraise the role of assessment and diagnosis on non-alcoholic fatty liver for CT.Methods:60 patients with non-alcoholic fatty liver were divided into treatment group and contrast group in average,the patients in treatment group were treated by Xiaozhihugan capsule and Dangfeiliganning capsule,and those in contrast group were treated by Kezhi capsule and Shuifeijibin capsule.Changes of symptom,liver function,blood fat,ultrasonic report and liver CTN were observed.Results:In the treat group,the liver function,blood fat and liver CT value were improved obviously,which had superiority to that of contrast group.CT can diagnose the degree of fatty liver accurately and appraise curative effect,but ultrasonic report has no specific data and is inconvenient to statistics.Conclusions:Treatment group has notable curative effect on non-alcoholic fatty liver;CT is the important index of diagnosis and appraisement of curative effect on non-alcoholic fatty liver.

Objective To investigate the effect of small interfering RNA(siRNA)-expressing plasmid targeting connective tissue growth factor(CTGF) on the expressions of its mRNA and protein in cultured human keloid fibroblasts(hKFs).Methods Constructed siRNA-expressing plasmids targeting CTGF were transfected into hKFs by Dosper package.Then the transfected cells were treated with transforming growth factor 1(TGF-?1,10 ng/ml).Normal hKFs cells and those with TGF-?1 treatment served as normal control and control groups respectively.The expression level of CTGF mRNA and protein were detected by real-time fluorescent quantitative PCR(RQ-PCR) and Western blotting respectively.Results The expression level of CTGF mRNA was only 56.6% of that of the normal control(P

The garlic oil and oil of Oenothera erythrosepala Borb. in Compound Dashuan Capsules were analysized with several kinds of specific qualitative methods. The content of their main components was also determined by GC. These methods showed relatively high sensitivity and accuracy, and could effectively control the product quality.
