WHO released the International Classification of Functioning, Disability and Health (ICF) in 2001. ICF is a kind of classification of multi-purpose used for different disciplines and fields, it belongs to by WHO for different applications in the field of health and to establish the international classification of family, it is a tool for internationally accepted, its overall goal is to provide a unified, standard language and framework to describe the condition of health and health-related. This article will review the application status of ICF at home and abroad, to explore the nursing of ICF application value, in order to explore the application of ICF in nursing standardized terminology space.

The cis-epoxysuccinate hydrolase (CESH) from Rhizobium strain BK-20 is the key enzyme for L(+)-tartaric acid production. To establish a highly efficient and stable production process, we first optimized the enzyme production from Rhizobium strain BK-20, and then developed an immobilized cell-culture process for sustained production of L(+)-tartaric acid. The enzyme activity of free cells reached (3 498.0 +/- 142.6) U/g, and increased by 643% after optimization. The enzyme activity of immobilized cells reached (2 817.2 +/- 226.7) U/g, under the optimal condition with sodium alginate as carrier, cell concentration at 10% (W/V) and gel concentration at 1.5% (W/V). The immobilized cells preserved high enzyme activity and normal structure after 10 repeated batches. The conversion rate of the substrate was more than 98%, indicating its excellent production stability.

Objective To investigate the influences of different mechanical ventilation modes on ventilator?induced diaphragm dysfunction (VIDD). Methods The patients received invasive mechanical ventilation in our ICU after lower abdomen surgery were enrolled into 3 groups according to different ventilation modes. The data of the 3 groups were analyzed. According to the offline results, patients were divided into two groups, the success of weaning as the dependent variable, the clinical indicators with statistical significance as the independent variable, the Logistic regression analysis was performed to analyze the ventilator weaning. Results The mechanical ventilation time, 48 h reintubation rate and the length of ICU stay in the A/C mode group were significantly higher than those in the SIMV mode group and the PSV mode group. The weaning success rate in the A/C mode group was significantly lower than that in the SIMV mode group and the PSV mode group, with significant difference (P<0.05). Weaning success group and weaning failure group had significant differences in the proportion of three ventilation modes (P < 0.05). With weaning as dependent variable, APACHE Ⅱ score, ALB and ventilation mode as independent variables, logistic regression analysis was performed using the enter method. APACHE Ⅱ and ventilation mode were independent influencing factors for weaning. Conclusion Compared with the A/C mode, the SIMV mode and the PSV mode have less influence on VIDD and high weaning success rate in the mechanical ventilation process of patients post?lower abdomen surgery. No significant difference was found between the SIMV mode and the PSV mode in their influence on weaning.

Objective To investigate the ultrasonic and pathological features of porcine striped muscle injury from thermal and chemical factors respectively, and to analyze the limitation of ultrasound diagnosis given by doctors with different skill levels. Methods An experimental study using fresh porcine striped muscle in vitro was designed, where the injury were caused by microwave ablation (2 450 MHz) and Anhydrous acetic acid (99.8%) injection separately. Blind to pathologic results, the two-dimensiona sonograms taken from each model were analyzed by sonographers with different skill levels independently. Finally, the diagnoses were evaluated and compared among them. Results Two-dimensional sonograms showed distinct changes of the textures in both injury models, which was characterized as the disappearance of regular tissue structure. However, the corresponding histopathology revealed obvious differences between the two interventions on ultrasonograms. There was no statistical difference between chief physician and attending doctor (both of them had over 5-year experiences on skeletal muscle ultrasound ) in identifying the ultrasonic features of boundary, shape and muscle texture (Kappa=0.933, 0.845, 0.789;Kappa=0.790, 0.935, 0.865, all P<0.05). Compared with residents′diagnosis, there were signiifcant differences in identifying the ultrasonic features of echo level and muscle texture in both injury models:Echo level in thermal injury group:chief physician vs residents, Kappa=0.323;attending doctor vs residents, Kappa=0.297. Texture feature in thermal injury group:chief physician vs residents, Kappa=0.259;attending doctor vs residents, Kappa=0.112. Texture feature in chemical injury group:chief physician vsresidents, Kappa=0.253;attending doctor vs residents, Kappa=0.070. Conclusions Microwave ablation and Anhydrous acetic acid can cause different histopathologic changes in correspondence with various features on two-dimensional sonograms. But ultrasonographers with different skill levels leads to signiifcant variations in identiifcation and qualitative diagnosis, which is impossible to be quantitatively analyzed. Chief physician and attending doctor can draw a consistent conclusion and demonstrate the ultrasounic characteristics in porcine striped muscle injury model from thermal or chemical factors.

Objective To observe the in vitro inhibitory effects of brucea javanica oil on human washed platelet and explore the possible mechanism.Methods Human washed platelets were mixed withdifferent concentration of brucea javanica oil which were divided into four groups[untreated control group,negative control group,9.0% of brucea javanica oil group,and 22.5%of brueea javanica oil group].The maximal ratio of platelet aggregation induced by adenosine liphosphate(ADP),arachidonic acid(AA),collagen,and thrombin,respectively,was measured with platelet aggregation analyzer.The expressions of fibrinogen receptor(FIB-R)and P-selectin(CD_(62p))on external membrane of activated platelet were determinated with flow cytometry.The F-actin of cytoskeletal structure in activated platelet was detected by SDS-PAGE.Results At 9.0% of brucea javanica oil,the maximal ratio of platelet aggregation[(57.7±4.0)%,(62.2±3.9)%,(66.9±5.0)%and(71.8±5.1)%]induced by ADP,AA,collagen,and thrombin,was significantly lower than that[(75.3±4.1)%,(79.3±4.8)%,(80.6±5.4)%,(84.1±6.2)%]at negative control(0% of brucea javanica oil)(P<0.01),but makedly higher than that[(39.2±3.5)%,(45.8±3.4)%,(51.2±3.9)%and(56.7±4.8%)]at 22.5%,respectively(P<0.01).The inhibitory rate of platelet aggregation(47.9%,42.2%,36.5%and 32.6%)at 22.5%of brucea javanica oil was notably higher than that(23.4%,21.6%,17.0%and 14.6%)at 9.0%,respectively(P<0.001).There was a negative correlation between brucea javanica oil concentration and the aggregation ratio of platelet stimulated by the four agonists,respectively(r=-0.952,-0.961,-0.970,-0.975,P<0.001).At 9.0% of brucea javanica oil,the expression levels of FIB-R[(64.7±4.0)%]and CD_(62p) [(3.91±0.21)%] of platelet activated by ADP were significantly lower than that[(85.5±4.6)%and (5.05±0.27)%]at negative control,but remarkably higher than that[(36.2±3.9)%and(2.34±0.15)%]at 22.5%,respectively(P<0.01).There was a much higher inhibitory rate of platelet aggregation(57.7%)at 22.5%than that(24.3%)at 9.0%(P<0.01).The ratios(1.68±0.10 and 1.77±0.12)of F-actin photodensity at 22.5%and 9.0%to that in blank control were significantly lower than that(2.22±0.15)at negative control(P<0.01)but there was no statistical difference between the ratios in the group of 9.0%and 22.5%brucea javanica(P>0.05).Conclusions brucea javanica oil has special inhibitory effect on activated platelet and thrombosis in a dose-dependent manner.The mechanism is to inhibit the expression of fibrinogen receptor on external membrane of activated platelet,which is also related to the inhibition of F-actin and secretion of platelet.

Objective To investigate the expressions of guanylyl cyclase-c(GC-C) and caudal-type homeobox transcription factor 2 (CDX2) in human gastric tissues and precursor lesions and its significance. Methods The cancerous and paracancerous (5 cm from cancer lesion )samples from 30 cases of gastric cancer and 32 samples including 23 intestinal metaplasia and 9 dysplasia were collected. The mRNA expressions of GC-C and CDX-2 were detected by reverse transcriptase-polymerase chain reaction (RT-PCR) and proteins of GC-C and CDX-2 were measured by using Western blot and immunofluorescence methods. Results The mRNA expressions of GC-C and CDX-2 were absent in paracancerous tissues, but were 66.7% and 63.3% in cancerous tissues, respectively(P=0. 000). The Western blot indicated that expressions of GC-C and CDX-2 were 19/30 and 17/30 in cancerous tissues, but absent in paracancerous tissues(P=0. 000). The immunofluorescence examination revealed that GC-C and CDX-2 expressions were 39.1% and 39.1% in intestinal metaplasia, 55.6% and 55.6% in dysplasia, and 56.7% and 60.0% in cancerous tissues, respectively, but absent in paracancerous tissues. Moreover, expressions of GC-C and CDX-2 showed a statistical difference between intestinal-type and diffuse-type of gastric cancer (P＜ 0.05) ,but had no correlation with age, sex, size of the lesion, clinical stage and lymphnode metastasis. The positive correlation was found in expressions of GC-C and CDX2 between intestinal metaplasia and cancerous tissues(r=0. 4524 and 0. 3845, P= 0. 037 and 0. 0408, respectively). Conclusions The over expressions of GC-C and CDX2 in human gastric cancer is associated with precursor lesions and may play an important role in the carcinogenesis of gastric cancer. The examination of GC-C and CDX2 expressions will be helpful in diagnosing gastric cancer and precursor lesions.
