Objective To evaluate the diagnostic value of color doppler imaging in lower limb deep vein thrombosis.Methods Application of color doppler ultrasonography,58 patients with clinically confirmed deep vein thrombosis were examined by the two-dimensional image,color characteristics and spectral characteristics of blood flow.Results The group of 58 cases had deep venous thrombosis,in which 37 cases were left leg,18 cases were right lower extremity,3 cases were lower limbs.By thrombosis of upper:iliofemoral type(central)in 35 cases,4 cases of pe-ripheral and mixed type in 19 cases.Conclusion Doppler ultrasound imaging to diagnose deep venous thrombosis was an effective method,and it had some guidance to select treatment methods.

Hyperoxia, including hyperbaric oxygen (HBO) and high-concentration oxygen (HO), has an important therapeutic effect on various ophthalmological diseases, such as retinal vein occlusion, ischemic optic neuropathy and central serous chorioretinopathy. However, excessive inhalation of oxygen of high-concentration or high atmospheric pressure can cause damage of ocular tissue, in which the lens opacity and retinopathy of prematurity (ROP) are the most common complications following hyperoxia exposure. At present, the pathogenesis of hyperoxia-induced ocular injury is still unclear thoroughly, and it may be related to oxidative stress, lipid peroxidation and inflammation. This article reviewed the current advance in the mechanism and the potential prevention of hyperoxia-induced the lens,retina and other ocular injuries.

Bilingual teaching is a hot issue in the current medical education reform.This paper discussed the practice of bilingual teaching in ophthalmology education and explored the improvement of teaching materials,enhancement of teaching staff training and promotion of multimedia-based,web-based and PBL-based bilingual teaching in order to provide references for improving the quality of ophthalmology teaching.

Objective To investigate the state of self-perceived burden (SPB) and depression and to explore the relationship between them for patients with chronic respiratory diseases.Methods 95 patients with chronic respiratory diseases were investigated by the Self-Perceived Burden Scale (SPBS) and Self-Rating Depression Scale (SDS).Results The average score of SPBS was (33.64±10.23) points,which was at the middle level,90.5％ of patients showed different levels of burden,and 34.7％ of patients were at the high level.The average score of SDS was (50.23±11.93),the index was 0.63,which was at the middle to high level,74.7％ of patients showed different levels of depression,and 33.7％ of patients were at the high level.There was a positive conrelation between SPB and depression.Conclusions Patients with chronic respiratory diseases had obvious SPB and depression,and there was a close relationship between them.With chronic respiratory diseases breaking out repeatedly and more severe year by year,most patients have high level of burden and negative emotions.Nurses should take proper measures and psychological interventions to help patients face to the diseases optimistically,and to improve patients' emotion state and enhance their physical and mental health.

Objective To explore the application of multislice computed tomographyic ( MSCT) perfusion imaging in the assessment of acute cerebral infarction. Methods 50 patients who initially diagnosed as acute cerebral infarction in 6 hours after their outbreak of infarction were selected. The Siemens semsation 4 MSCT was used to scan the patients and form time versus concentration curve analysis, including the comparision of region cerebral blood flow (CBF) between the necrosis region and the normal region, region cerebral blood volume (CBV), mean transit time ( MTT). Each case had to be examined by computed tomography at least once a week after infarction. Results 50 patients were found having a lower CBF and CBV in their necrosis region compared with the other side(P＜0.05) ,and had a longer MTT in their necrosis region compared with the other side( P ＜0.05) ,45 patients were observed a shrink of the size of the infarction region compared with the perfusion image in first 6 hours when they were reexamined by CT a week later(P ＜0.05) ,which proved the exist of ischemic penumbra area around the infarction center. Conclusion The multislice computed tomographyic perfusion imaging technology could define the infarction region and size at the early stage of acute cerebral infarction. It also provided clues to indicate the exist of a vascular area around the necrosis centre. It could diagnose acute cerebral infarction at hyperacute period and provide image proof for the thrombolysis in early period and treatment in individual manner.

Objective To observe plasma albumin,total bilirubin and serum inflammatory factors,gonadal hormone levels in men with bipolar disorder,and to provide evidence for the diagnosis of the disease.Methods 48 men with bipolar disorder were selected as disease group,and 42 cases of male physical examination were selected as control group.Plasma albumin,total bilirubin and serum inflammatory factors,gonadal hormone levels of the two groups were detected.Results The levels of serum albumin and total bilirubin of the disease group were (43.4 ± 3.9)g/L and (9.4 ±1.9)μmol/L,which were lower than those of the control group[(49.6 ±3.0)g/L and (11.8 ± 2.1)μmol/L],the differences were statistically significant (t =8.361,5.692,all P <0.05).The levels of serum inflammatory factors IL -1 and IL -4 of the disease group were (4.2 ±2.2)ng/L and (3.3 ±1.8)ng/L,which were higher than those of the control group[(1.3 ±1.0)ng/L and (1.6 ±0.9)ng/L],the differences were statistically significant (t =7.858,5.542,all P <0.05).There were no significant differences in the levels of serum LH,PRL, FSH and PRG between the two groups(all P >0.05).The serum level of E2 of the disease group was (23.2 ± 16.1)pg/mL,which was lower than (35.9 ±18.0)pg/mL of the control group,the serum T level of the disease group was (10.8 ±4.9)ng/mL,which was higher than (4.2 ±1.6)ng/mL of the control group,the differences were statistically significant(t =3.533,8.344,all P <0.05).Conclusion Plasma albumin,total bilirubin and serum IL -1β,IL -4 levels can be used as references for clinical diagnosis of bipolar disorder,and serum E2 and T levels can be used as risk factors for bipolar disorder.

Objective To investigate the effects of professional benefit recognition to stress coping of tuberculosis nurses. Methods A total of 82 tuberculosis nurses were assigned into experimental and control groups by random digits table method with 41 cases each. The experimental group was given four times of professional benefit recognition interventions in additional to regular training, while control group was just given regular training. The two groups were asked to complete the Professional Benefit Recognition questionnaires and Stress Coping Style questionnaires before the intervention and 1 month after the intervention, respectively. Results Before the intervention, the scores of the Professional Benefit Recognition questionnaires and Stress Coping Style questionnaires between two groups had no significant difference (P>0.05). After the intervention, the Professional Benefit Recognition questionnaires scores of experimental group increased from ( 2.93 ± 0.40) points to (3.81±0.38) points that was significantly better than that of control group(2.99±0.39) points, and there were significant differences (t=49.337,-60.834, P<0.05). The immature and mixed Stress Coping Style questionnaires scores of experimental group: self- accusation, illusion, avoidance, rationalization were (0.51 ± 0.13) , (0.51 ± 0.24), (0.56 ± 0.21), (0.51 ± 0.16) points, which were significantly lower than before the intervention (0.70 ± 0.09), (0.65 ± 0.10), (0.67 ± 0.14), (0.67 ± 0.08) points and that of control group (0.63 ± 0.16), (0.65 ± 0.18), (0.68 ± 0.18), (0.64 ± 0.13) points, with the difference being significant (t=-4.071--2.541, P<0.05). The mature coping scores of the experimental group:problem solving, appealing were (0.70 ± 0.10), (0.67 ± 0.13) points, which were significantly higher than that of control group (0.63 ± 0.12), (0.58 ± 0.15) points and that of experimental group before the intervention (0.55 ± 0.12), (0.51 ± 0.11) points, with the difference being significant (t=2.308, 2.098, P <0.05). Conclusions Professional benefit recognition interventions can improve professional benefit recognition and stress coping style, is beneficial to nurses' physical and mental health and nursing quality.

In order to explore the cellular mechanism of antishock effect of anisodamine (654-2), the changes of intramitochondrial magnesium during late hemorrhagic shock were observed. Results showed that there exists a negative correlation between the blood plasma magnesium concentration and arterial blood pressure in shocked animals and at the same time the magneium content of liver mitochondria reduced significantly; 654-2 prevented the decrease of mitochondria magnesium and the increase of blood plasma magnesium, and improved the prognosis of the shocked animals. These results indicate that 654-2 may protect the liver mitochondria of shocked animals at a cellular and subcellular levels.

Endotoxin can markedly decrease the activity of erythrocyte acetylch-olinesterase (AchE)in rat both in vitro and vivo. Furthermore, the AchE activity can be further inhibited by the presence of self-plasma. The AchE activity of erythrocyte in dog can also be inhibited with endotoxin, while it has little effect on human erythrocyte AchE. SDS-polyacrylamide gel electrophoresis shows that the patterns of membrane protein are different in different animals, so it is possible that the structure of membrane protein plays an important role in reaction among endotoxin-red cells.

How to grasp the developing direction of Traditional Chinese Medicine(TCM) theory is the kernel of the TCM subject.In studying the theory of TCM,the three key propositions,how to keep the self main body,how to show the theoretic value and how to perform the durative innovation,must be answered.For keeping the main body,it must be clarified in unscrambling the origin,and be hold in the changeable reform,and be stand out under the scientific background.For showing the theoretic value of TCM,its academic value must be embodied in life(sciences),its leading value must be displayed during the subject development,and its guiding value must be emerged in clinical practice.For performing the durative theoretic innovation,it must be extended during inheriting the classical theory,and be improved in clinical practice,and be created in interdisciplinary crossing.Only in this way,would the basic theory of TCM acquire a breakthrough.
