Hilar cholangiocarcinoma always presents with a mass, thickness of the bile duct wall or nodules in the bile duct. Computed tomography (CT) can demonstrate the above findings with high partial resolution as well as dilation of the intrahepatic bile duct. CT can show the field and the involvement of adjacent vessels on 3D reconstruction images for hilar cholangiocarcinoma spreading along the lumen of the bile duct. CT images can also demonstrate vessel involvement when evaluating the resectability. When combined with 3D reconstruc-tion, the sensitivity and specificity of CT imaging can reach 90.5% and 91.7% , respectively, for detecting vessel involve-ment.

Objective To investigate the distribution of syndromes in hospitalized hypertensive patients with maintenance hemodialysis. Methods A investigation-table of Chinese medicine was established and used in 105 eases for survey in clinic to discover the regularity. Results The occurrence rate from high to low of asthenia syndrome symptoms was: deficiency syndrome of both yin and yang, yin asthenia, deficiency of both vital energy and yin, yang asthenia, and the deficiency of qi. The occurrence rate from high to low of evil domination was: turbid damp, stagnation of qi, blood stasis, and fluid stagnation. Conclusions The clinical feature of hypertensive patients with maintenance hemodialysis was mainly asthenia of healthy energy combining with sthenia evil.

Objective Investigation of satisfaction of clinical nurses and analysis of the influence factors.Methods The ERG theory of Clayton Alderfer is used as the framework to design the questionnaires,for questionnaire investigation of 249 nurses in the hospital in a stratified sampling,Results The score of general satisfaction of nurses for their work is 3.40±0.58;the satisfaction of nurses for the management of their leaders and teamwork is high,as the satisfaction scores are 4.01±0.76 and 3.60±0.71 respectively;their satisfaction for salary,welfare and social identity is low,as the scores are 2.46±0.86 and 2.50±1.02 respectively.Work satisfaction varies with departments,academic levels,monthly income,work shifts,age,seniority,and objectives for their choice of nursing as profession.Conclusion Managers are prompted to enhance their work in view of the satisfaction scores on survival,mutual relations and growth,as well as factors affecting satisfaction,and take various incentives to improve overall satisfaction of nurses.

AIM: By introducing the thinking and experience of professor Deng Tietao to treat myasthenia gravis, to improve the therapeutic effect and prognosis.benefiting vital qi had been the main line throughout the whole process of phasized that while we grasp spleen-asthenia, we must give consideration to other organs at the same time, regulate and treat the patient with multistrengthening muscle and increasing strength (radix astragali, radix codonopsis pilosulae, rhizoma atractylodis macrocephalae, rhizoma cimicifugae, pericarpium citri reticulatae, radix fici simplicissimae, etc.), the disease had been treated with different dosage of drugs according to the py for one or two years, even though the symptoms had disappeared completely.RESULTS: Because of grasping the root cause, therapy with multi-means and modified prescription according to the varied symptoms, it had a satisfactory effect. An excellent therapeutic effect had been obtained with the decoction for strengthening muscle and increasing strength, which is created by Deng himself.CONCLUSION: Deng's theory holds that myasthenia gravis is mainly due to spleen-asthenia, and related to other four organs (with a predominance of kidney), and the therapy should be strengthening the spleen-qi, so the prescription was selected for strengthening muscle and increasing strength (which is created by Deng himself), with radix astragali being in a lager quantity. Moreover, he paid more attention to psychological therapy and dietary regulation. The Deng's theory is of considerable clinical significance in guiding treatment of myasthenia gravis.

Objective To investigate the epidemiological characteristics of hospitalized hypertension patients with different metabolic abnormalities associated with cardiovascular disease.Methods 1 843 patients with diagnosis of hypertension were selected,including 327 patients with metabolic syndrome as the research object.Metabolic syndrome of different age,gender,abnormal components epidemic status were analyzed.Results Positive rates of overweight,dyslipidemia,hyperglycemia,cardiovascular disease in 327 patients were 42.20％,37.92％,35.17％,71.25％,the highest positive rate for cardiovascular disease was significantly higher than the other three indexs(x2 =56.22,73.28,85.51,all P ＜ 0.05).There was no significant differences in the rates of overweight between men and women (x2 =0.42,P ＞ 0.05).Dyslipidemia and hyperglycemia incidence of women were significantly more than those of men,there was statistically significant difference (x2 =5.73,6.47,all P ＜ 0.05).The incidence of cardiovascular disease in males was high than that in females (x2 =24.66,P ＜ 0.05).Conclusion Preventive different metabolic abnormalities need to take different measures according to age and gender.Weight control,blood lipids and blood sugar are the key to the prevention of cardiovascular disease.

Objective To study the effect of He-Ne laser at lower power on proliferation and differentiation of embryo midbrain nerve cell.Methods The embryo midbrain nerve cell of rat embryo were randomly divided into one control group and three experimental groups.The cells in experimental groups were respectively irradiated at different time:3 min(A组),6 min(B组),10min(C组),each day.After ten days,we counted the concentration rate and determined the content of protein and the amount of superoxide dismutase(SOD)and malonyldialolehyde(MDA).Results The concentration rate of group A and of group B significantly increased than that of the control group(P

The electrochemical behaviors of parathion(PT) on nano-Al2O3 film modified electrode(nano-Al2O3/GCE/CME) were investigated. It was found that the redox peak currents of PT remarkably increased and the oxidation peak potential negatively shifted at the nano-Al2O3/GCE/CME. All the experimental parameters were optimized and a simple and sensitive electroanalytical method was developed for the determination of PT. The oxidation peak current was linear with the concentration of PT over the range from 2.5×10-9 to 1.0×10-7 mol/L and 1.0×10-7 to 1.0×10-5 mol/L. A low detection limit of 1.0×10-9 mol/L was obtained for 30 s accumulation at open circuit(S/N=3). The relative standard deviation(n=10) was 3.8% for 1×10-5 mol/L PT. The proposed method was used for the quantitative analysis of PT in some vegetables and the results were satisfactory.
