Objective: To observe the effect of acupoint massage plus Vitalstim electrical stimulation on deglutition function and surface electromyography (SEMG) of deglutition muscle groups. Methods: A total of 60 patients with deglutition disorder after stroke were selected and divided into an electrical stimulation group, a massage group and an integrated group according to the random number table method, with 20 cases in each group. Patients in these three groups were given the same routine rehabilitation training for deglutition. In addition, patients in the electrical stimulation group were given extra Vitalstim electrical stimulation, patients in the massage group were given extra acupoint massage on the head, face and neck, and patients in the integrated group were given extra acupoint massage plus Vitalstim electrical stimulation. Fujishima Ichiro food intake level scale (FILS) was scored before and after treatment. The swallowing duration and maximal amplitude of masseter muscle in SEMG were evaluated before and after treatment. Results: After treatment, the FILS score and the maximal amplitude of recruitment potential generated by muscular contraction of masseter muscle group in the three groups were higher than those before treatment (all P<0.05), and the swallowing duration of masseter muscle group was shortened compared with that in the same group before treatment (all P<0.05). After treatment, the FILS score in the integrated group was higher than that in the electrical stimulation group and the massage group (both P<0.05). The swallowing duration of masseter muscle group measured by SEMG was lower than that in the electrical stimulation group and the massage group (both P<0.05), while the maximal amplitude was higher than that of the electrical stimulation group and the massage group (P<0.05). After treatment, there were no significant differences in the FILS score, swallowing duration and maximal amplitude of masseter muscle group between the electrical stimulation group and the massage group (all P>0.05). Conclusion: Both acupoint massage and electrical stimulation can improve the deglutition function in patients with deglutition disorder after stroke, and improve the coordination and flexibility of masseter muscle. The integration of the two is more effective.

Objective To investigate the quality of life and its related factors in maintenance peritoneal dialysis (MPD)patients and their primary caregivers;to analyze the correlation of the quality of life MPD patients and their primary caregivers.Methods A total of 92 MPD patients and their primary caregivers were chosen for the study.The patients were performed peritoneal dialysis catheterization in our hospital nephrology from June 2008 to June 2012 and had regularly peritoneal dialysis.General clinical data and questionnaire survey of all patients and primary caregivers were analyzed retrospectively.Results The total score of SF-36 was (86.75 ±20.76)in MPD patients.There was no significant difference in the scores of SF-36 liking gender or marital status(P >0.05),while there were significant differences in the score of SF-36 such as age,dialysis time,medicare reimbursement and work status(P <0.05).Multiple linear regression analysis showed that age was related factor for the quality of life of MPD patients.The total score of SF-36 was (121.46 ±18.57)in primary caregivers.There were significant differences in the score of SF-36 in primary caregivers with different gender,age,length of day care,care duration and family/social relations(P <0.05).Multiple linear regression analysis showed that gender,age and time of day care were related factors for the quality of life in primary caregivers.Correlation analysis showed that the score of SF-36,PCS and MCS in MPD patients were positively correlated with the score of SF-36 and MCS in primary caregivers respectively.Conclusions The quality of life in MPD patients is poor,and age is the main related factor.The quality of life is lower in primary caregivers than in normal people,and gender,age and time of day care are the related factors.The quality of life in MPD patients is positively correlated with the quality of life in primary caregivers.To improve the quality of life in patients,the quality of life in primary caregivers should be improved by varieties of ways.

This study was aimed to explore the effect of bortezomib on proliferation and apoptosis of acute monocytic leukemic cells SHI-1 and the function of Bcl-2 gene family including Bcl2l12, Bcl-2 and Bax in its apoptosis. SHI-1 cells were cultured and treated with bortezomib of different concentrations for different time. MTT assay was used to detect the proliferation and apoptosis, Annexin-V staining, mitochondrial transmembrane potential (DeltaPsim) and DNA aga-rose gel electrophoresis were used to investigate apoptosis of SHI-1 cells. RT-PCR was used to analyze the levels of Bcl2l12, Bcl-2 and bax mRNA in SHI-1 cells treated with bortezomib for 0, 6, 12 and 24 hours. The results showed that bortezomib inhibited the proliferation of SHI-1 cells in time-and doze-dependent manners, the IC(50) at 24 and 48 hours were 54.13 nmol/L and 5.45 nmol/L respectively. Bortezomib could induce apoptosis of SHI-1 cells in time-dependent manner, increase expression of Annexin-V positive cells, decrease DeltaPsim of SHI-1 cells and result in DNA fragmentation and morphologic changes of apoptosis. RT-PCR showed that Bcl2l12 mRNA expression was up-regulated, bcl-2 mRNA expression was down-regulated and bax mRNA expression was not changed obviously. It is concluded that bortezomib inhibits the proliferation of SHI-1 and induces apoptosis in which Bcl2l12 and Bcl-2 gene can be ones of the main genes taking part in.

BACKGROUNDPlasma galectin-3, a mediator of fibrogenesis and inflammation, its potential to associate with type 2 diabetes (T2DM) is poorly investigated. Here, we explored its interaction with the serum galectin-3 and vascular complications.

METHODSWe conducted a population-based cross-sectional survey in Zhejiang, China involving 165 men and 119 women (age range, 43 - 84 years), investigating the relationship between serum galectin-3 and vascular disease in patients with T2DM.

RESULTSSerum galectin-3 was higher in subjects with T2DM than that in control participants (27.4 vs. 17.6 ng/ml, P < 0.001). Compared with subjects with galectin-3 values in the lowest quartile, those with values in the highest quartile had an increased likelihood of vascular complications (4th quartile odds ratio (OR) 2.52, 95% confidence interval (CI), 1.25 - 4.07). Increased risk of micro- or macrovascular complications correlated with serum galectin-3 concentration (ORs 11.4 and 8.5, respectively). An increased number of vascular complications was associated with high serum galectin-3 levels (P < 0.05). Patients with serum galectin-3 levels > 25 ng/ml had an elevated risk of diabetes relative to patients with levels < 10 ng/ml (OR for any vascular complication 2.64, for heart failure 3.97, for nephropathy 4.09, for peripheral arterial disease (PAD) 4.18; all P < 0.05). Complication risk was higher in patients with neurogenic, stroke, or retinopathy complications, but this difference was not significant after risk factor adjustment. Serum galectin-3 levels correlated with diabetes duration, C-reactive protein (CRP) levels, and albuminuria.

CONCLUSIONHigh galectin-3 values were associated with increased odds of developing heart failure, nephropathy, and peripheral arterial disease in patients with T2DM.

Objective: To explore the effects of citric acid on patients with severe burn complicated with acute renal injury treated by continuous renal replacement therapy (CRRT). Methods: Medical records of 83 patients with large area of burn complicated with acute renal injury admitted to intensive care unit (ICU) of our department from January 2015 to December 2018 and meeting the inclusion criteria were analyzed retrospectively. The patients were divided into heparin group [n=43, 25 males and 18 females, aged (35.0±2.5) years] and citric acid group [n=40, 22 males and 18 females, aged (37.0±6.6) years] according to different anticoagulation methods. After admission, routine support treatment and CRRT were performed after being diagnosed with acute renal injury in patients in 2 groups. Patients in heparin group were treated with low molecular weight heparin for anticoagulation with first dosage of 20 U/kg and an increase of 2.5 to 5.0 U per hour, and patients in citric acid group were given citric acid of 0.02 g/mL with dosage of 150~200 mL/h for anticoagulation. The use time of blood filter, recovery time of urine volume, and time of staying in ICU, and platelet count, activated partial thromboplastin time (APTT), prothrombin time (PT), and serum creatinine, urea nitrogen, cystatin C, procalcitonin, C-reactive protein, and neutrophil, leukocyte count, blood sugar, aspartate aminotransferase (AST), alanine aminotransferase (ALT), and heart rate, body temperature, and mean arterial pressure before treatment and post treatment hour (PTH) 24 were recorded. Besides, occurrence of hemorrhage, hypocalcemia, metabolic acidosis, metabolic alkalosis, and death within 28 days post injury were recorded. Data were processed with t test and chi-square test. Results: The use time of blood filter of patients in citric acid group was (28.7±3.2)h, significantly longer than (19.4±2.6) h in heparin group (t=14.139, P<0.01). The recovery time of urine volume and time of staying in ICU of patients in citric acid group were respectively (7.6±0.9) and (9.6±1.3) d, significantly shorter than (9.2±1.5) and (11.2±1.8) d in heparin group (t=5.516, 4.697, P<0.01). Before treatment, there were no statistically significant differences in platelet count, APTT, and PT of patients in 2 groups (t=1.235, 0.515, 1.279, P>0.05). At PTH 24, the platelet count of patients in citric acid group was significantly higher than that in heparin group (t=10.947, P<0.01), and APTT and PT of patients in citric acid group were significantly shorter than those in heparin group (t=7.069, 9.142, P<0.01). Before treatment, there were no statistically significant differences in serum creatinine, urea nitrogen, and cystatin C of patients in 2 groups (t=1.684, 1.878, 1.472, P>0.05). At PTH 24, the serum creatinine, urea nitrogen, and cystatin C of patients in citric acid group were significantly lower than those in heparin group (t=7.778, 9.776, 5.117, P<0.01). Before treatment, there were no statistically significant differences in serum procalcitonin and C-reactive protein of patients in 2 groups (t=1.413, 0.898, P>0.05). At PTH 24, the serum procalcitonin and C-reactive protein of patients in citric acid group were significantly lower than those in heparin group (t=2.635, 2.297, P<0.05). Before treatment, there were no statistically significant differences in neutrophil, leukocyte count, blood sugar, AST, and ALT of patients in 2 groups (t=0.555, 0.816, 0.470, 1.896, 0.982, P>0.05). At PTH 24, the neutrophil, leukocyte count, blood sugar, AST, and ALT of patients in citric acid group were significantly lower than those in heparin group (t=2.054, 3.314, 7.185, 2.151, 3.013, P<0.05 or P<0.01). Before treatment, there were no statistically significant differences in heart rate, body temperature, and mean arterial pressure of patients in 2 groups (t=1.406, 0.474, 0.720, P>0.05). At PTH 24, the heart rate, body temperature, and mean arterial pressure of patients in citric acid group were significantly lower than those in heparin group (t=2.307, 4.498, 2.056, P<0.05 or P<0.01). The incidence of hemorrhage of patients in citric acid group while in hospital was significantly lower than that in heparin group (χ²=4.949, P<0.05). There were no statistically significant differences in incidence of hypocalcemia, metabolic acidosis, metabolic alkalosis, and death rate within 28 days post injury of patients in 2 groups while in hospital (χ²=3.346, 0.884, 0.297, 0.324, P>0.05). Conclusions Citric acid has significant anticoagulant effect on patients with large area of burn complicated with acute renal injury treated by CRRT, which can prolong the use time of the blood filter, shorten the recovery time of urine volume and time of staying in ICU, improve renal function indexes, blood biochemical indexes, and inflammation indexes, maintain the stability of internal environment, and reduce the risk of hemorrhage.

On March 14, 2017, a thirty years old male severe burn patient accompanied by asphyxia, sudden cardiac arrest, and acute respiratory distress syndrome was admitted to Zhengzhou First People′s Hospital. During the shock stage, the pulse contour cardiac output was monitored for the restrictive rehydration, tracheotomy was performed, and fibrobronchoscope lavage was performed for the treatment of inhalation injury and pulmonary infection. An alternate application of suspended bed and turning bed was conducted to balance the treatment of cerebral edema and pulmonary infection; targeted antibiotics were used for anti-infective treatment; multiple operations were performed for eschar excision and skin grafting. At last, the wounds were all healed, the lung infection was cured, and the patient was discharged with severe disturbance of consciousness. Asphyxia and acute respiratory distress syndrome post-cardiopulmonary resuscitation are serious complications in severe burn patients. The clinical treatment of such patients is very difficult and should be highly alerted.

Objective:To explore the value of renal injury marker protein in early diagnosis of acute kidney injury (AKI) in burn patients with delayed resuscitation.Methods:The retrospective case-control research was conducted. Forty-three burn patients with delayed resuscitation (27 males and 16 females, with age of 18-75 (35±3) years)who were admitted to Zhengzhou First People′s Hospital from May 2018 to May 2020 met the inclusion criteria. The patients were divided into AKI group with 23 patients and non-AKI group with 20 patients according to whether AKI occurred within 7 days after burns. The gender, age, deep partial-thickness burn area, full-thickness burn area, and acute physiology and chronic health evaluation Ⅱ of patients were compared between the two groups.The fluid supplement volume and serum creatinine at 12, 24, and 48 h after burn, serum albumin/fibrinogen ratio (AFR), urinary heat shock protein 70 (HSP70), tissue inhibitor of metalloproteinase-2 (TIMP-2)×insulin-like growth factor binding protein 7 (IGFBP-7), and neutrophil gelatinase associated lipocalin (NGAL)at 12, 24, 48, 72, 120, and 168 h after burn were detected.Data were statistically analyzed with Mann-Whitney U test, analysis of variance for repeated measurement, independent-samples t test, chi-square test and Bonferroni correction. The independent variable to predict the occurrence of AKI was screened by multi-factor logistic regression analysis. The receiver′s operating characteristic curve was drawn for predicting the occurrence of AKI in burn delayed resuscitation patients, and the area under the curve (AUC), the best threshold, and the sensitivity and specificity under the best threshold were calculated. Results:The gender, age, deep partial-thickness burn area, full-thickness burn area, acute physiology and chronic health evaluation Ⅱ of patients in two groups were similar ( χ2=1.98, t=1.98, 1.99, 1.99, 1.99, P>0.05). The fluid supplement volume of patients in AKI group at 24 and 48 h after burn was significantly less than that in non-AKI group ( t=15.37, 6.51, P<0.01). The serum creatinine of patients in AKI group at 12, 24, and 48 h after burn was significantly higher than that in non-AKI group ( Z=2.16, 5.62, 6.72, P<0.01). The serum AFR of patients in AKI group at 12, 24, 48, 72, 120, and 168 h after burn was significantly lower than that in non-AKI group ( t=16.14, 35.35, 19.60, 20.47, 30.20, 20.17, P<0.01). The levels of urinary HSP70 of patients in AKI group at 12, 24, 48, 72, 120, and 168 h after burn were (6.89±0.87), (6.42±0.73), (5.81±0.72), (5.17±0.56), (4.63±0.51), (3.89±0.51) μg/L, which were significantly higher than (3.89±0.75), (3.57±0.63), (2.66±0.41), (1.83±0.35), (1.48±0.19), (1.28±0.19) μg/L in non-AKI group ( t=12.00, 13.61, 17.39, 22.98, 26.34, 21.59, P<0.01). Urinary TIMP-2×IGFBP-7 and NGAL of patients in AKI group at 12, 24, 48, 72, 120, 168 h after burn were significantly higher than those in non-AKI group ( t=26.94, 101.11, 35.50, 66.89, 17.34, 14.30, 14.00, 13.78, 12.32, 14.80, 21.36, 22.62, P<0.01). Urinary HSP70 and serum AFR at 12 h after burn, urinary TIMP-2×IGFBP-7 and NGAL at 24 h after burn were included into multi-factor logistic regression analysis (odds ratio=2.42, 3.47, 7.52, 5.61, 95% confidence interval=1.99-2.95, 1.86-3.92, 2.87-9.68, 2.14-14.69, P<0.01). For 43 patients with burn delayed resuscitation, the AUC of receiver′s operating characteristic curve of serum AFR at 12 h after burn for predicting AKI was 0.739 (95% confidence interval=0.576-0.903), the optimal threshold was 9.90, the sensitivity was 82%, and the specificity was 90%. The AUC of urinary HSP70 at 12 h after burn was 0.990 (95% confidence interval=0.920-1.000), the optimal threshold was 1.40 μg/L, the sensitivity was 98%, and the specificity was 96%. The AUC of urinary TIMP-2×IGFBP-7 at 24 h after burn was 0.715 (95% confidence interval=0.512-0.890), the optimal threshold was 114.20 μg 2/L 2, the sensitivity was 91%, and the specificity was 95%. The AUC of urinary NGAL at 24 h after burn was 0.972 (95% confidence interval=0.860-1.000), the optimal threshold was 78 μg/L, the sensitivity was 95%, and the specificity was 96%. Conclusions:Urinary HSP70 and NGAL have higher value in early diagnosis of AKI in burn patients with delayed resuscitation.

Objective To explore self-care abilities and current status of fatigue and loneliness in peritoneal dialysis patients, and to determine the correlation between their self-care and fatigue & loneliness. Methods Totals of 237 cases with peritoneal dialysis followed up by Nephrology Department in the First Affiliated Hospital of Zhengzhou University were selected and surveyed by General patient information questionnaire, Exercise of Self-Care Agency Scale ( ESCA) , Multidimensional Fatigue Inventory-20 ( MFI-20) , and UCLA Loneliness Scale ( Chinese version ) . Results Scores of self-care ability in peritoneal dialysis patients were ( 92. 18 ± 15. 23) points, in the level above the average. Scores of fatigue in peritoneal dialysis patients were (61.24±11.72) points, and of loneliness (46.28±5.34), both higher than norm (P<0.01). Self-care ability of peritoneal dialysis patients showed a negative correlation with level of fatigue and loneliness ( P<0. 01) . It was revealed in multiple stepwise regression analysis that influencing factors of self-care abilities in peritoneal dialysis patients included comprehensive fatigue, less activity, physical fatigue and loneliness. Conclusions When making nursing measures for peritoneal dialysis patients, their fatigue and loneliness should be assessed. Targeting measures should be intervened to eliminate their fatigue and loneliness, so as to improve their self-care ability and quality of life.

Objective:To explore the correlation between nurses ' empowerment and professional identity in Cardiac Intensive Care Unit (CCU) . Methods:From June to September 2021, 164 nurses working in CCU of 8 ClassⅢ Grade A hospitals in Zhengzhou were selected as the research object by convenience sampling. The General Information Questionnaire, Professional Identity Scale for Nurses and Empowering Leadership Behavior Scale were used to conduct the questionnaire survey. A total of 164 questionnaires were distributed, and 158 valid questionnaires were recovered, with a valid recovery rate of 96.34% (158/164) .Results:Among 158 CCU nurses, the total scores of the Professional Identity Scale for Nurses and the Empowering Leadership Behavior Scale were (93.24±6.05) and (84.30±7.15) respectively. There was a positive correlation between the total score of Professional Identity Scale for Nurses and the total score of Empowering Leadership Behavior Scale ( P<0.05) . Conclusions:CCU nurses ' professional identity is at the middle level, while empowerment is closely related to their professional identity. Nursing managers should pay attention to the implementation of effective empowerment behavior, improve the professional identity of CCU nurses, and promote the stability of the nursing team.
