Objective To explore the effect of the clinical case oriented management model on nurses comprehensive ability, psychological and critical mind. Methods In 2014 on the implementation ofroutine clinical case management modelas the control group, collected 97 cases of clinical cases. In 2015 on the implementation ofthe clinical case oriented management modelas the observation group, collected 110 cases of clinical cases. Compared two methods of management to improve the nurse management theoretical knowledge, clinical practice ability and deal with the size of the case skills help. When/after clinical special case found the influence for nurses, including psychology, work in the nursing work will, enthusiasm, independent ability to deal with related cases and the nurse critical thinking ability, etc. Results The proportion of the nurses thought that it was helpful to improve the management of theoretical knowledge, clinical practice ability and deal with the size of the case skills and the case analysis of satisfaction were 98.79%(244/247), 99.19%(245/247), 98.79%(244/247), 99.60%(246/247) in the observation group, and 88.57%(217/245), 87.35%(214/245), 87.76%(215/245), 90.61%(222/245) in the control group. The differences were statistically significant (χ2=21.390-27.571, P < 0.01). The proportion of the nurse considered that special case on the psychological effects of nursing work, engaged in the willingness and enthusiasm were the main factor were 15.79%(39/247), 13.77%(34/247), 11.34%(28/247) in the observation group, and 31.84%(78/245), 31.02%(76/245), 30.61%(75/245) in the control group. The differences were statistically significant (χ2=17.475, 21.097, 27.611, P < 0.01). After special case, the percentage of nurses to independently handle the case, help others, loss rates were 97.57%(241/247), 2.02% (5/247), 0.40% (1/247) in the observation group, and 85.71% (210/245), 12.24% (30/245), 2.04% (5/245) in the control group. The proportion of nurses to independently handle the case in the observation group was higher than that in the control group, but the ratio of nurses to help others, loss rates in the observation group were lower than those in the control group, the differences were statistically significant (χ2=22.647, P<0.01).Critical thinking score, the observation group of nurses in the search for truth, open mind, analytical ability, system organization, judging thinking self-confidence, curiosity, cognitive maturity, such as total score were respectively (43.24±4.01), (43.03±4.12), (47.66±4.23), (44.21± 3.92), (44.00 ± 4.97), (52.13 ± 4.44), (48.23 ± 4.85), (319 ± 14.57) points. The control group nurses were respectively (39.00±3.56), (38.90±3.28), (43.65±2.47), (40.55±1.99), (39.00±3.40), (47.87±4.01), (41.89± 5.11), (292.23 ± 6.02) points. The differences were statistically significant(t =12.15-24.19, P < 0.01). Conclusions The clinical case oriented management model can improve nurses comprehensive ability, reduce the adverse impact of the special case for nurses, improve the clinical nurses' critical thinking ability, to ensure patient safety.

Objective To evaluate the effect of salicylic acid on skin barrier function and the efficacy of salicylic acid combined with flumetasone ointment for the treatment of atopic dermatitis (AD).Methods Sixtyfour patients with AD (including 31 males and 33 females) aged 18 to 58 years were recruited into the present study.Four lesional areas of similar size and severity were selected at the similar body sites of both sides of each patient,and randomly classified into four groups to be topically treated with compound flumetasone ointment (containing 0.02％ flumetasone and 3％ salicylic acid,compound flumetasone group),flumetasone 0.02％ ointment (flumetasone group),salicylic acid 3％ ointment (salicylic acid group) and vehicle (control group),respectively;two normal skin areas were chosen from apparently normal skin on the similar body sites of both sides of each patient and topically treated with salicylic acid 3％ ointment (salicylic acid group) and vehicle (control group) respectively.All of these preparations were applied twice a day for 3 weeks.Transepidermal water loss (TEWL) was measured by a Tewameter MPA580 (Courage & Khazaka,Germany) at the baseline as well as on week 1,2 and 3 after initiation of treatment.Symptom and sign scores were evaluated before and after the treatment.Meanwhile,two normal skin areas were selected on bilateral forearm of 30 healthy controls and treated with 3％ salicylic acid ointment (salicylic acid group) and vehicle (control group) respectively twice a day for 3 weeks,and TEWL was measured before treatment as well as on week 1 and 3 after initiation of treatment.Results In the healthy controls,TEWL value showed no significant difference between the salicylic acid group and control group at any of these time points.As far as the lesional skin was concerned,no statistical difference was observed in TEWL value at the baseline between the four groups ((34.26 ± 20.82) vs.(33.02 ±16.71) vs.(34.16 ± 18.03) vs.(33.81 ± 17.11) g· m-2· h-1,P ＞ 0.05),but significant difference was noted after treatment (repeated measurement data analysis of variance,F =39.57,P ＜0.01),with the TEWL value being (22.38 ± 16.16),(17.04 ± 12.74),and (15.34 ± 13.13) g·m-2·h-1 respectively in the compound flumetasone group on week 1,2 and 3,(24.63 ± 17.08),(20.37 ± 9.53),(19.06 ± 9.17) g·m-2·h-1 respectively in the flumetasone group,(26.49 ± 8.59),(21.91 ± 8.46),(21.20 ± 9.38) g·m-2·h-1 respectively in the salicylic acid group,and (29.80 ± 12.48),(26.16 ± 8.31),(25.52 ± 6.05) g·m-2·h-1 respectively in the control group.In detail,the decrease in TEWL value was stronger in the compound flumetasone group than in the flumetasone group on week 1,2,and 3 (all P ＜0.05),in the salicylic acid group than in the control group (P ＜0.05 or 0.01),but similar between the flumetasone group and salicylic acid group.In non-lesional skin,the salicylic acid group showed a more intense decrease in TEWL value compared with the control group on week 2 and 3 (both P ＜0.05).Both the cure rate and response rate were significantly higher in the compound flumetasone group than in the flumetasone group (53.1％ vs.34.4％,x2 =4.57,P＜0.05;83.1％ vs.64.1％,x2 =6.90,P＜0.01).Conclusions The salicylic acid 3％ ointment shows a reparative effect on skin barrier in patients with AD,and the compound flumetasone ointment is superior to the flumetasone ointment in the treatment of AD.

Objective: To investigate the causes of disease among patients with liver disease hospitalized in Department of Infectious Diseases in our hospital and the changes in such causes within the past 20 years. Methods: A retrospective analysis was performed for the clinical data of 7570 patients who were admitted to our hospital from January 1995 to December 2015. The chi-square test was used for the statistical analysis of constituent ratio. Results: Of all 7570 patients with liver disease, 4930 (65.13%) had viral hepatitis, 332 (4.39%) had immune disease, 215 (2.84%) had drug-induced liver injury, 192 (2.54%) had fatty liver disease, 88 (1.16%) had schistosome-induced liver disease, 160 (2.11%) had inherited metabolic diseases, and 20 (0.13%) had vascular disease; 689 (9.1%) still had no clear cause of disease at discharge. The proportion of patients with viral hepatitis was 77.61% in the first 10 years and 59.19% in the last 10 years (P < 0.01). As for liver disease caused by hepatotropic virus, there were significant increases in the proportion of patients with hepatitis C or hepatitis E from the first to the last 10 years (hepatitis C: 2.24% vs 15.56%, P < 0.01; hepatitis E: 18.61% vs 23.07%, P < 0.05), while there were significant reductions in the proportion of patients with hepatitis B (68.14% vs 60.01%, P < 0.05) or hepatitis A (10.7% vs 1.36%, P < 0.05). The proportion of patients with immune diseases was 0.82% in the first 10 years and 6.08% in the last 10 years (P < 0.01). There were also certain changes in the proportion of patients with liver disease caused by other reasons. Conclusion There is a large proportion of patients with viral hepatitis among patients with liver disease hospitalized in Department of Infectious Diseases in a large general hospital, especially hepatitis B and E caused by hepatotropic virus. There is a certain change in the epidemiology of liver disease within the past 20 years, with a reduction in the proportion of patients with viral hepatitis and an increase in the proportion of patients with non-infectious liver diseases. There is a large proportion of patients with unknown causes of liver disease.

Objective:To investigate the etiological mechanism in single small subcortical infarction (SSSI) with different imaging features.Methods:The patients registered in a database of ischemic stroke in the Department of Neurology of the First Affiliated Hospital of Zhengzhou University from January 2016 to December 2019 were analyzed. According to the lowest slice (LS) and the total number of involved slices (TNS) on diffusion-weighted imaging, the SSSI was divided into 3 types: proximal SSSI (pSSSI; LS≤2), distal and large SSSI (dl-SSSI; LS>2, TNS>2) and distal and small SSSI (ds-SSSI; LS>2, TNS≤2). The clinical and imaging features among 3 different lesion patterns were compared by using χ 2 test, Kruskal-Wallis H test and multiple Logistic regression analysis, etc. Results:In the 3 groups of ds-SSSI ( n=205), dl-SSSI ( n=157) and pSSSI ( n=166), the prevalences of parent artery disease (PAD)[10.7% (22/205) , 19.1% (30/157) , 42.8% (71/166), respectively, χ 2=54.89, P<0.001], coronary artery disease [8.3% (17/205), 14.0% (22/157), 16.9%(28/166), respectively, χ 2=6.44, P=0.040] and severe white matter hyperintensities (sWMHs)[58.0% (119/205), 43.3% (68/157), 41.0% (68/166), respectively, χ 2=12.94, P<0.001], the level of serum homocysteine (Hcy)[18.01 (13.54, 25.56), 16.03 (12.50, 21.09), 14.72 (11.12, 19.14) μmol/L, respectively, H=19.36, P<0.001], and the National Institutes of Health Stroke Scale (NIHSS) score[2(1, 3), 3(1, 4), 3(2, 6), respectively, H=39.53, P<0.001] showed statistically significant differences. Multiple Logistic regression analysis showed that compared with dl-SSSI patients, the lesion pattern of patients with higher proportion of PAD ( OR=3.12, 95% CI 1.86-5.24, P<0.001) was closer to pSSSI; the lesion pattern of patients with higher serum Hcy level ( OR=1.02, 95% CI 1.00-1.04, P=0.046) or higher proportion of sWMHs ( OR=1.79, 95% CI 1.12-2.86, P=0.015) was closer to ds-SSSI, and the lesion pattern of patients with higher proportion of PAD ( OR=0.50, 95% CI 0.27-0.93, P=0.029) or higher NIHSS score ( OR=0.84, 95% CI 0.77-0.92, P<0.001) was closer to dl-SSSI. Conclusions:The pathogenesis of ds-SSSI tends to be cerebral small vessel disease. The pathogenesis of pSSSI is related to atherosclerosis. The patients with dl-SSSI have the intermediate characteristics of pSSSI and ds-SSSI and may be unstable.

Enzyme is an efficient and green biocatalyst, and widely used in many areas. Immobilized enzyme is superior to its free form in a variety of properties. Enzyme immobilization studies started in the 1970s in China. Till now, immobilized enzymes are widely applied in the fields of food, medical, energy, environmental management, among others. However, there are still some defects such as no universal method and the high cost. Therefore, based on the relatively mature traditional immobilization technologies, efforts have been made to innovate immobilization technologies. As a result, many new immobilization technologies focusing on new carriers and methods are continuously generated. Coupling with more than ten years' study on enzyme immobilization, we present here recent development and application of new immobilization technologies, as well as suggestions to future development of immobilization technology.
