The basic nursing quality is an important dial of the general administration level and the basic personnel quality of a hospital.Many causes have led to the down trend of the basic nursing quali- ty.After a specific analysis of the causes of such a trend,important measures and solutions have been put forth,The first is to strengthen the moral education of the profession and upgrade the quality of the nursing staff.The second is to adopt the "group responsibility" administration and gradually carry out a systimatic integrated nursing so that a transformation of nursing models is put to practice,The third is to broaden the outlet of human resources so that personnel are rationally employed and the rate of job— taking raised.The last one is to heighten the initiative of the nursing staff through the rational opera- tion of the "incentive"mechanism in accordance with the law of values.

Chinese Journal of Ultrasonography 2015;24(2):140-143
Objective To evaluate the value of transvaginal two-dimensional ultrasound(2D-TVS)and transvaginal three-dimensional ultrasound (3D-TVS) in the diagnosis of intrauterine lesions with abnormal uterine bleeding.Methods Intrauterine lesions for 171 patients underwent 2D-TVS followed by 3D-TVS in the same session.Within 10 days of the sonographic session,each patient underwent pathologic histology examination after hysteroscopy examination or surgery therapy,which was considered the reference standard.For each of the two imaging methods,sensitivity,specificity,and accuracy were calculated.Results The results of 2D-TVS and 3D-TVS had good agreement with pathological results in endometrial hyperplasia,endometrial polyps,uterus submucous myoma and endometrial cancer.For 2D-TVS,sensitivity was 84.5%,71.4%,86.8%,66.7%,and specificity was 86.7%,90.7%,97.0%,98.7%,respectively; For 3D-TVS,sensitivity was 91.4%,87.3%,92.1%,83.3%,and specificity was 93.8%,96.3 %,97.7 %,98.7 %,respectively.The diagnose accordance rate of the 3D-TVS for intrauterine lesions was statistically higher than that of the 2D-TVS (89.5% vs 78.9%,P <0.05).Conclusions The sensitivity and diagnose accordance rate of 3D-TVS was higher than that by 2D-TVS,3D-TVS plays an important role in the diagnosis and differential diagnosis of intrauterine lesions.

Objective To explore the effect of xuezhikang on blood lipids,vascular endothelial function and redox balance in patients with carotid atherosclerosis.Methods A total of 108 inpatients with carotid atherosclerosis in cardiology department were randomly divided into two groups:xuezhikang group (n = 54) and cholestyramin group (n= 54).Before and after treatment,the levels of total cholesterol (TC),triglyceride (TG),low density lipoprotein cholesterol (LDL-C),nitric oxide (NO),endothelin-1 (ET-1),reduced glutathione (GSH) and oxidized glutathione (GSSG) of all patients were measured.The GSH/GSSG as redox potentials were calculated according to Nernst equation.Results After 12 weeks of treatment,the levels of blood lipids were lower than before treatment in xuezhikang group [TC:(3.94±1.36) mmol/L vs.(5.68±1.47) mmol/L;LDL-C:(2.28±1.11) mmol/L vs.(3.43±1.36) mmol/L;TG:(1.54±0.59) mmol/L vs.(1.73±0.66)mmol/L;t=3.915,4.160,2.187;P<0.01,0.01,0.05,respectively],and the levels of blood lipids also decreased in cholestyramin group [TC:(4.15 ± 1.29) mmol/L vs.(5.73 ± 1.52)mmol/L;LDLC:(2.56± 1.06) mmol/L vs.(3.37± 1.35) mmol/L;TG:(1.69±0.57) mmol/L vs.(1.72±0.67) mmol/L;t=3.760,4.035,1.893;P<0.01,0.01,>0.05,respectively].In xuezhikang group,ET-1,GSSG and GSSG/GSH ratios decreased significantly [(121.71 + 59.11) ng/L vs.(154.43±63.06) ng/L;(30.42± 1.59) μmol/L vs.(33.93±1.74) μ mol/L;-146.1±4.4vs.-142.3±4.3;t=2.168,2.325,4.168;P<0.05,0.05,0.01,respectively],and NO,NO/ET-1 ratios,GSH and GSH/GSSG increased significantly [(64.40 ± 18.86) μmol/L vs.(48.41 ±16.53) μmol/L;(0.54±0.19) vs.(0.33±0.16);(321.27±56.47) μmol/L vs.(286.11±38.23)μmol/L;(10.56±1.70) vs.(8.65±1.18);t=3.725,3.987,3.894,4.168;all P<0.01].Conclusions For patients with carotid atherosclerosis,both xuezhikang and cholestyramin could lower blood lipids efficiently,but only xuezhikang could protect vascular endothelial function partly,and makes plasma redox imbalance shift the balance.

Objective: Our aim was to study whether the cellular bronchoalveolar lavage fluid (BALF) profile was associated with the parameters of pulmonary function tests. Methods:Lung function tests and BAL were carried out in 18 untreated, non-smoking patients suffering from sarcoidosis and 18 normal subjects. Results:(1)Lung function tests were normal at rest in patients with sarcoidosis(P>0.05), the single breath carbon monoxide diffusing capacity decreased (P<0.05),and the small airway function decreased too (P<0.05).(2)The percentage of lymphocytes in BALF of sarcoidosis increased comparing with the normal subjects(P<0.01),and the ratio of CD+4 to CD+8 in BALF increased significantly in sarcoidosis(P <0.05), furthermore, the increase of both the percentage of lymphocytes and the ratio of CD+4 to CD+8 in BALF of sarcoidosis were well nagatively correlated with the decrease of the percentage of DLCO (r=-0.67, P<0.01 and r=-0.55, P<0.05, respectively), the decrease of mid-expiratory flow at 50% of vital capacity (FEF50%) was well correlated with the increase of the percentage of lymphocytes in BALF of sarcoidosis (r=-0.54, P<0.05). Conclusion:Pulmonary diffusing capacity(DLCO) was significently correlated with BALF lymphocyte phenotype,so was small airway function,and can act as the marker of activity of sarcoidosis.

AIM: To investigate the effects of Lipopolysaccharide(LPS) and interieukin 1 receptor antagonist (IL- 1ra) on mesangial cells proliferation and nitric oxide synthesis. METHODS: Glomerular mesangial cells from SD rats were cultured. The first and second passages of cultured cells were used for the experiment. LPS and LPS plus IL- 1ra were added in cell cultures, respectively. By using chemical method the nitrite in supernatants was measured ,3H- TaR incorporation was determined to evaluate the GMC proliferation. Northern and slot hybridizations were performed to detect the expression of iNOS mRNA. RESULTS: There were expression of iNOS mRNA, more production of nitrite(0.64 + 0.25 vs 0. 12 + 0.06 nmol/104 cell) in supernatants and GMC proliferation(3735 + 1177.9 vs 1785 + 280.6) in LPS group compared to the control. While compared with LPS group, in LPS + IL- 1ra GMC group, expression of iNOS mRNA decreased by 40%, nitrite increased(3.28 + 0.33 nmol/104 cell), proliferation of GMC decreased (818 + 77.27). CONCLUSION: LPS could activate the GMC to express iNOS mRNA and produce more nitrite. IL - 1ra could partially inhibit the effects of LPS on the expression of iNOS mRNA in GMC, but not nitrite. There is no synchronous correlation between NO production and GMC proliferation.
