To discuss the ultrasonic testing intelligent infusion pump tubing bubble method. When the ultrasonic wave goes through the interface of two different media, the reflection occurs, refraction, transmission and other physical phenomena can occur because of a large extent acoustic impedance difference between water and air, which can be used in this physical phenomenon, by monitoring the ultrasonic energy (output voltage) can be obtained if the extent of the presence of bubbles and bubble exists within the infusion tube. By measuring the penetration of ultrasonic energy, we detected air bubbles within the infusion line. Ultrasound can accurately detect air bubbles in the infusion line, which is the main method of detecting air bubbles for infusion pump.

Metabolic memory means if the hyperglycemia can't be controlled at early stage of diabetes,chronic complications such as diabetic retinopathy (DR) will continue to develop even if the blood glucose level maintains normal level at later stage.Oxidative stress plays an important role in the metabolic memory of DR,which interacts with the nitrative stress,advanced glycation end products,genetic modification and endoplasmic reticulum stress in the pathogenesis of DR.Further elucidation of the relationship between oxidative stress and metabolic memory of DR can open the way for the discovery of novel therapeutic targets to prevent DR progression.

Objective To explore the application effect of critical thinking applied in the intravenous infusion.Methods To give nurses who worked in the Neurosurgery Department from January to April 2012 training lessons of critical thinking so that they could analyze,judge,formulate and implement corresponding nursing measures during the intravenous infusion process through their critical thinking.Then the successful rate of venepuncture for patients and the patients' satisfaction degree with nursing before and after the critical thinking training lessons were observed.Results The successful rate of venepuncture for patients and the patients' satisfaction degree of nursing were apparently improved after the nurses received critical thinking training.The difference was of statistical significance.Conclusions After the implementation of critical thinking training during the intravenous infusion process for nurses,nurses puncture skills is enhanced,infusion swelling and complications are reduced,and the quality of clinical nursing care and patients' satisfaction degree of nursing is improved.

Fifty-two patients with chronic thrombeembolism (41 male, 11 female) aged 33-67 yr underwent pulmonary endarterectomy between 1997-2008. Anesthesia was induced with etomidate, fentanyl/ sufentanil and rocuronium/vecuronium and maintained with large doses of narcotics supplemented with low concentrations of isoflurane/sevoflurane if necessary. Swan-Ganz catheter was placed after induction of anesthesia. Trausesophageal echocardiography was monitored. Bilateral pulmonary thromboembolism was performed using profound hypothermia with circulatory arrest. After operation, 35 patients still had sustained pulmonary hypertension (67%). Nervous system complications occurred in 7 patients ( 14% ). Six patients developed lung bleeding (12%) during and after operation and 4 patients infection (8%). The mortality was 15%.

Background The pathogenesis of diabetic retinopathy (DR) involves a variety of biological pathways.Recently,inflammation factor has been thought to paly an important role in the pathogenesis of DR.Studies show that the concent of tumor necrosis factor-α (TNF-α) is increased in high-glucose environment,which leads to the abnormality of tight junction protein and follows by blood-retinal barrier (BRB) damage.Polysaccharides of dendrobium candidum (PDC) can inhibit the overexpression of TNF-α,but its effect on TNF-α in early DR procedure has been unelucidated.Objective This study was to investigate the effects of PDC on permeability of BRB and its mechanism in daibetic rats.Methods Fifty clear adult SD rats were divided into normal control group,diabetic model group and low-(100 mg/[kg · d]),moderate-(200 mg/[kg · d]) and high-dose (300 mg/[kg · d]) PDC groups,10 rats for each group.Streptozotocin was intraperitoneally injected to establish diabetic model in 40 rats,expect for normal control group.PDC at the concentrations of 100,200 and 300 mg/(kg · d) was intragastrically administered in the low-,moderate-and high-dose groups respectively at 6 weeks after modeling,and normal saline solution was used at the same way in the normal control group and diabetic model group.Evans blue was perfused via cardic chamber and eyes were obtained.Evants blue leakage was measured to evaluate the BRB permeability.The relative expressions of TNF-α,zonula occludens-1 (ZO-1),occludin and claudin-5 proteins were detected by Western blot;TNF-α contents in the retina and serum of the rats were detected by ELISA.Results The leakage concents of Evans blue in the retinas were (12.68±1.30),(30.45±2.60),(22.12±1.15),(17.99±1.00) and (21.49±1.00) in the normal control group,diabetic model goup and low-,moderate-and high-dose PDC groups,respectively,and the retinal leakage concents in the diabetic model group were significantly higher than those in the normal control group,and the retinal leakage contents in the low-,moderate-and high-dose PDC groups were lower than those in the diabetic model group (all at P ＜ 0.01).Western blot showed that the relative expression level of retinal TNF-α was significantly higher in the diabetic model group compared with the normal control group(1.12±0.10 vs.0.27±0.03),and that in the diabetic model group was significantly higher than that in the normal control group;while the relative expression levels of retinal TNF-α in different doses PDC groups were significantly lower,and the relative expression levels of retinal ZO-1,occludin and claudin-5 were significantly higher than those in the diabetic model group (all at P＜0.05).ELISA showed that the concentrations of retinal and serum TNF-α were higher in the diabetic model group compared with the normal control group,and those in the different doses of PDC groups were lower than those in the diabetic model group (all at P＜0.05).No significant differences were found among various doses of PDC groups (all at P＞0.05).Conclusions PDC can improve the permeability of BRB by down-regulating the expression of TNF-α and up-regulating the expressions of tight junction proteins in the retina of diabetic rats,which is probably related to suppressing the development of early DR.

Objective To investigate the changes of serum levels of IL-24, IFN-γand IL-4 in patients with condyloma acuminatum (CA) after treatment. Methods Forty-two patients with CA who experienced no recurrence within 3 months after successful treatment were enrolled in this study. Double-antibody sandwich enzyme-linked immunoabsorbent assay (DAS ELISA) was performed to determine the serum levels of IL-24,IFN-γand IL-4 in these patients before and 3 months after successful treatment as well as in 35 normal human controls. Results The untreated patients showed a lower level of serum IFN-γ (9.65 ± 3.70 vs. 15.49 ± 3.85ng/L, P ＜ 0.01) and a higher level of serum IL-4 and IL-24 (15.91 ± 6.14 vs. 10.48 ± 5.08 ng/L, 141.84 ±44.01 vs. 103.20 ± 41.37 ng/L, both P ＜ 0.01 ) compared with the controls. No significant difference was observed for the above parameters between the serum samples from the controls and patients 3 months after successful treatment. Conclusions Cellular immunity is impaired in patients with CA, which may be involved in the immunopathogenesis of CA.
