Objective To evaluate the implementation feasibility of the nurse performance appraisal and allocation plan based on the holistic nursing mode, and the clinical effect in mobilizing nursing staff's work enthusiasm and ensuring the quality of nursing service. Methods The nurse performance appraisal and allocation plan were further improved based on the previous research of this index system construction. The model were implemented in 32 clinical departments of Yidu Center Hospital of Weifang City. Four aspects data were collected for analysis six months later to evaluate the effect. They were nurses on merit pay distribution satisfaction, patients′satisfaction, doctors′satisfaction with nursing job, different clinical departments′nursing quality scores. Results Six months later, four factor scores of nurses to the satisfaction of merit pay distribution were significantly improved. The scores of fairness and impartiality evaluation of the merit pay distribution, incentive effect evaluation, pay and return on equity evaluation and performance pay gap rationality evaluation were higher than before [(3.39 ±0.64) points vs. (1.88 ±0.33) points, (3.28 ±0.74) points vs. (1.84 ±0.49) points , (3.28 ±0.71) points vs. (1.88 ±0.42) points and (3.38 ±0.67) points vs. (2.01±0.53) points, t=19.28, 16.22, 18.08, 16.79, all P<0.05]. Patients′satisfaction, doctors′satisfaction with nursing job and different clinical department' nursing quality scores were significantly increased as well [(99.14±0.82) points vs. (96.78±0.84) points, (96.59±0.91) points vs. (93.59±1.27) points and(97.67±0.41) points vs. (95.70±1.13) points]. Difference had statistical significance (t=11.79, 11.63, 9.60, P<0.05). Conclusions The performance salary allocation plan can effectively improve the hospital nurses on performance salary allocation satisfaction, patients′satisfaction, doctor′s satisfaction with nursing work and the quality of nursing department, and has good incentive in arousing the work enthusiasm of nursing staff and in ensuring the quality of nursing service.

Objective To explore the effect of chlorophyll derivative on wound healing after hem-orrhoidectomy.Methods A total of 124 patients with circular hemorrhoids after procedure for pro-lapse and hemorrhoids(PPH)were selected and divided into control group and experimental group.The granulation formation time,wound healing time,degree of wound edema and pain before and after treatment,serum biochemical indicators,adverse reactions and complications were compared between two groups.Results The granulation formation time and wound healing time in the experimental group were significantly shorter than those in the control group(P＜0.05).After treatment,wound ede-ma score and pain score as well as serum levels of tumor necrosis factor-α(TNF-α)and interleukin-6(IL-6)in both groups were significantly lower than those before treatment,and these indexes after treatment in the experimental group were significantly lower than those in the control group(P＜0.05),but the differences of the above indexes before and after treatment in the experimental group were significantly higher than those in the control group(P＜0.05).After treatment,the levels of ser-um epidermal growth factor(EGF),fibronectin(FN)and basic fibroblast factor(bFGF)in both groups increased significantly,and these indexes after treatment in the experimental group were signifi-cantly higher than those in the control group(P＜0.05).Conclusion Chlorophyll derivative can promote granulation formation and wound healing after hemorrhoidectomy,and reduce degrees of ede-ma and pain.

Organ transplantation is the optimal treatment for end-stage organ failure. Nevertheless, organ shortage is a global problem, which limits further development of organ transplantation. Recent research shows that genetically modified pig may become a realistic alternative source of clinical organ transplantation donor. Xenotransplantation may serve as one of the effective measures to resolve the problem of organ shortage. Since 2021, 2 cases of living xenotransplantation and 6 cases of xenotransplantation in brain death recipients have been performed worldwide, and phase Ⅰ clinical trial of xenotransplantation has been launched, and the results have exceeded expectations. Therefore, in this article, recent clinical trial results of xenotransplantation in living and brain death recipients were retrospectively analyzed, and scientific, technical and ethical issues related to clinical research of xenotransplantation were illustrated, hoping to provide reference for clinical research of xenotransplantation in China and promote the development of xenotransplantation in clinical practice.

OBJECTIVETo assess the efficacy of sacral neuromodulation (SNM) in patients with intractable constipation.

METHODSA total of 7 patients with intractable constipation were treated with pereutaneous test stimulation of the S3 nerve root and were assessed by sacral never stimulation system in our department from January 2013 to January 2014. Four of these 7 patients received operation for constipation before. The efficacy was assessed by bowel habit diary, clinic constipation scores, subjective questionnaire and clinical signs.

RESULTSThe constipation symptoms were improved significantly in all the 7 patients. The frequency and volume of defecation per week were increased obviously, and the average urine was increased. Six patients underwent permanent implantation of the SNS system. After a median 4 months follow-up, the defecation frequency increased from 0.6 ± 0.5 to 8.0 ± 2.5 per week (P<0.01), and the defecation time decreased from (22.9 ± 11.5) to (3.7 ± 0.8) min (P<0.01). The Cleveland clinic constipation score decreased from 24.6 ± 4.2 to 9.0 ± 0.9 (P<0.01), and the visual analogue scale(VAS) score increased from 8.1 ± 0.9 to 82.5 ± 5.2 (P<0.01).

CONCLUSIONSNM is a clinically efficacious, minimally invasive and safe new technique, which offers an alternative treatment for the patients with intractable constipation resistant to conservative treatment, especially for the patients refractory to traditional operations.

Objective: To analyze the relationship between family behaviors and overweight/obesity in primary and junior school students aged 6-14 years in Xuzhou, and to provide a reference for a targeted measure to prevent and control overweight and obesity. Methods: Using multistage stratified cluster random sampling, a total of 6 220 students aged 6-14 years old from 10 primary schools and 10 junior schools were investigated by a self-designed questionnaire. Chi-square and multivariate Logistic regression models were used to explore the relationship between family behaviors and overweight/obesity in primary and junior school students. Results: The rate of overweight/obesity in primary and junior boys was higher than that in primary and junior girls. The rate of overweight/obesity in urban students was higher than that of rural students(P<0.05). The Chi-square analysis showed that overweight of parents, irregular breakfast, eating fast food, eating sweets, drinking sweetened beverage, long screen time and short sleep duration were risk family behavior factors of overweight/obesity in primary and junior boy students(P<0.05). The risk family behavior factors of overweight/obesity in primary and junior girl students were overweight of parents, irregular breakfast, eating fast food and eating sweets(P<0.05). The risk family behavior factors of overweight/obesity, such as drinking sweetened beverage and short sleep duration, were also related to primary girls(P<0.05), and long screen time was related to junior girls(P<0.05). The multivariate Logistic regression showed that such family behavior factors as irregular breakfast(OR-boy=1.58, OR-girl=1.74), eating fast food(OR-boy=1.37, OR-girl=1.11), eating sweets(OR-boy=1.85, OR-girl=1.52), drinking sweetened beverage(OR-boy=1.64, OR-girl=1.33) and short sleep duration(OR-boy=1.56, OR-girl=1.69) were positively correlated with the prevalence of overweight/obesity in primary students. Long screen time was also correlated to overweight/obesity primary boy students(OR=1.18). Family behavior factors for child overweight and obesity induded overweight of parents(OR-boy=1.29, OR-girl=1.23) and eating sweets(OR-boy=1.44, OR-girl=1.51). Irregular breakfast(OR=1.51), eating fast food(OR=1.22), drinking sweetened beverage (OR=1.75) and long visual screen time (OR=1.15) were also positively correlated with the prevalence of overweight/obesity in junior boy students. Conclusion Family behavior factors were positively correlated with the prevalence of overweight/obesity in primary and junior students. The influence of family behavior factors were different between primary and junior students. Behavioral interventions based on family should be adopted to prevent and control the overweight/obesity of children.

Objective To investigate the changes and their significance of glutamate-aspartate transporter (GLAST) and glutamate transporter-1 (GLT-1) expressions in glial cells following spinal cord injury (SCI) in adult rats.Methods Twenty-five healthy female adult SD rats were randomly divided into control group (5 rats) and experimental group (20 rats).The contusive spinal cord injury models were prepared at T10 segment in the rats in the experimental group according to the modified Allen's method.At days 1,3,7 and 14 following SCI,five rats were sacrificed by cardiac perfusion and the spinal cord segments adjacent to the epicenter of injury were obtained at each time point after the neurological function of hind limbs was assessed using the modified Tarlov scale.Changes of GLAST and GLT-1 expressions were detected semi-quantitatively using immunofluorescence and computer image analysis system (IPP 6.0).Results (1) Single immunofluorescence:Moderate GLAST expression was found in the control group.The GLAST expression was increased slightly at day 1 after SCI,decreased progressively at days 3 and 7 after SCI,and increased slightly at day 14 after SCI.The GLAST expression in experimental group was significantly lower than those in control group at days 3,7 and 14 after SCI (P ＜ 0.05).Moderate GLT-1 expression was detected in the control group.The expression of GLT-1 was increased slightly at day 1 after SCI,decreased to the lowest at day 3 after SCI,and increased slightly at days 7 and 14 after SCI.The GLT-1 expression in experimental group was significantly lower than those in control group at days 3,7 and 14 after SCI (P ＜0.05).(2) Double immunofluorescence:GLAST expression was found on astrocytes in the control group.The GLAST expression in experimental group was decreased at day 1 after SCI,further decreased progressively at days 3 and 7 after SCI,and started to recover at day 14 after SCI.The coexpressions of GLAST and glial fibrillary acidic protein (GFAP) in experimental group were significantly lower than those in the control group at days 3 and 7 after SCI (P ＜ 0.05).The expression of GLAST was found on microglial cells in the control group.The expression of GLAST in experimental group was increased obviously at day 1 after SCI and increased progressively at days 3-14 after SCI.The coexpressions of GLAST and OX-42 in experimental group were significantly than those in the control group at days 3,7 and 14 after SCI (P ＜ 0.05).(3) Double immunofluorescence:GLT-1 expression was found on astrocytes in the control group.The GLT-1 expression was decreased at day 1 after SCI,further decreased progressively at days 3 and 7 after SCI,and started to recover at day 14 after SCI.The coexpressions of GLT-1 and GFAP were significantly lower than those in the control group at days 3 and 7 after SCI (P ＜ 0.05).The GLT-1 expression was found on microglial cells in the control group.The GLT-1 expression was increased obviously at day 1 after SCI and increased progressively at days 3-14 after SCI.The coexpressions of GLT-1 and OX-42 were significantly higher than those in the control group at days 1,3,7 and 14 after SCI (P ＜ 0.05).Conclusion The glutamate transporters GLAST and GLT-1 show different expression patterns in astrocytes and microglia following SCI in rats,which may be correlated with the roles of different glial cells in repair of spinal cord injury.

Objective To analyze the relationship between sleep duration, screen viewing time, and the prevalence of overweight/obesity among primary school students in Xuzhou. Methods Using a cluster sampling method, a total of 3 228 students (including 1 679 boys and 1 549 girls with an average age of 10.78±0.69 years) from grade one to six from 10 primary schools in Xuzhou underwent interview using a self?designed questionnaire containing basic characteristics, sleep duration, and screen viewing time. Data on height and weight were also collected. The relationship between sleep duration, screen viewing time, and overweight/obesity was analyzed using a logistic regression analysis. Results The prevalence rates of overweight among boys and girls were 16.56% and 11.94%, respectively (χ2=13.59, P<0.05). The prevalence rates of obesity among boys and girls were 14.47% and 10.07%, respectively (χ2=14.01, P<0.05). In total, 74.41% students reported a lack of sleep; the average sleeping time was (9.24±1.07) h. The average sleeping time among boys was (9.35 ± 1.12) h and among girls was (9.13 ± 1.03) h. The difference in sleep duration between boys and girls was significant (t=5.79, P<0.05). The differences in sleep duration and overweight/obesity were significant between both boys (χ2=18.62, P<0.05) and girls (χ2=21.14, P<0.05). Regarding screen viewing time, 17.29% of students spent more than 2 hours per day viewing a screen. The difference in screen viewing time between boys and girls was significant (Z=3.02, P=0.014). The proportion of children with screen viewing time of more than 2 h/d among overweight/obese and healthy weight male students was 29.50% (82/278) and 22.56% (316/1401), respectively, which was significantly different (χ2=6.18, P=0.01). However, there was no significant difference when examining the same groups among girls (12.98% (24/185;obese/overweight) vs . 9.97% (136/1364; healthy weight); χ2=1.59, P=0.21). After adjusting for parental obesity, eating sweets, and physical activity, logistic regression analysis showed that students who had a sleep duration less than 10 h/d had an odds ratio of 1.4 (95% CI: 1.15-1.71), the odds ratio for boys and girls was 1.56 (95% CI: 1.13-2.14) and 1.69 (95% CI: 1.15-2.46). The students who had a screen viewing time of more than 2 h/d had an odds ratio of 1.14 (95% CI: 1.05-1.80); the odds ratio for boys in this group was 1.18 (95% CI: 1.03-1.67). Conclusion Short sleep duration is a risk factor for being overweight/obese in both boys and girls. However, long screen viewing times were associated with being overweight/obese only in boys.

Objective:To explore the application of list nursing management combined with different artificial liver treatment modes in patients with liver failure.Methods:Fifty-three patients with liver failure hospitalized in Bethune Hospital of Shanxi Province from July 2020 to July 2021 were selected as the control group, 63 patients with liver failure hospitalized in Bethune Hospital of Shanxi Province from July 2021 to July 2022 were selected as the intervention group. According to the different treatment modes of artificial liver for patients, plasma exchange (PE), double plasma molecular adsorption system (DPMAS) and PE + DPMAS treatment were set up in the two groups. The control group received routine nursing care, while the intervention group received checklist nursing care in addition. The changes of albumin (ALB) and prothrombin time (PT) indexes before and after the different treatment modes were compared, together with the occurrence of complications between the two groups after the intervention.Results:The baseline data between the two groups was balanced, the difference had no statistical significant ( P>0.05). After the therapy, the level of ALB of patients who had accepted DPMAS and PE + DPMAS in the intervention group were 25.3(24.0, 27.9) and 23.2(22.4, 26.3) g/L, which were lower than the 28.2(26.3, 29.7) and 29.4(27.2, 30.0) g/L in the control group, the differences were significant ( Z = 2.47, 3.55, both P<0.05). After the therapy, the level of PT of patients in the intervention group under all three treatment modes were 15.8(14.8, 16.8), 22.7(19.2, 26.2) and 6.0(14.6, 20.0) s, which were lower than the 17.4(15.9, 20.9), 26.3(21.4, 36.4) and 21.2(16.9, 23.4) s in the control group, the differences were significant ( Z = 2.10, 2.07, 2.21, all P<0.05). In the intervention group, there were 6 cases of hypotension, anaphylaxis, bleeding, coagulation and infection under the DPMAS treatment mode, which was significant lower than the 11 cases in the control group ( χ2 = 4.97, P<0.05). There were 4 cases in the intervention group with the PE + DPMAS treatment mode occurred complications in above, which were significant lower than the 11 cases in the control group ( χ2 = 6.87, P<0.01). Conclusions:Artificial liver treatment can improve patients′ liver function and coagulation, and list nursing management may help to improve the effect of artificial liver treatment. It can improve nurses′ awareness of risk prejudgement, reduce various risks in the treatment process, reduce the incidence of adverse reactions, and enhance health care and patient satisfaction.
