Objective To investigate the clinical characteristics and its related influence factors of hyperuricemia in peritoneal dialysis patients. Methods A total of 152 peritoneal dialysis patients were enrolled. Patients were classified into hyperuricemia and normal serum uric acid (SUA)groups. Factors associated with hyperuricemia were analyzed. Results Hyperuricemia occurred in 112 cases(73.7%). There were significant differences in serum potassium, the incidence of hypertension, blood urea nitrogen, serum creatinine, serum phosphorus, parathyroid hormone, triglyceride between hyperuricemia and normal SUA groups(P<0.05). There was no significant difference in age, serum sodium, hemoglobin, serum albumin, prealbumin, serum calcium, serum iron, total protein, high sensitive C-reactive protein, serum glucose, total cholesterol, high density lipoproteins, low density lipoproteins, KT/V and PET(P>0.05). SUA levels was positively correlated with serum potassium, blood urea nitrogen and serum phosphorus(P<0.05). Conclusion Hyperuricemia was common in peritoneal dialysis patients, serum potassium levels is correlated with serum potassium, blood urea nitrogen and serum phosphorus. The timely treatment of hyperuricemia may improve the prognosis of peritoneal dialysis patients.

Objective To investigate the expressions and clinical significances of atrial brain natriuretic peptide precursor (PRO-BNP), homocysteine (Hcy) and erythrocyte sedimentation rate (ESR) in patients with unstable angina pectoris associated by Left ventricular systolic insufficiency. Methods A total of 130 patients with simple unstable angina pectoris and another 130 patients with unstable angina pectoris associated by left ventricular systolic insufficiency treated during January 2015 and October 2016 were selected as group A and group B respectively,and at the same period,130 healthy persons taking medical examination were selected as the control froup (group C). Serum levels of PRO-BNP,Hcy and ESR were detected in three groups,and the correlation between serums PRO-BNP,Hcy and ESR and left ventricular ejection fraction (LVEF) in group B were analyzed. Results Serum levels of in group A and B were significantly higher than those in group C,and the levels in group B were significantly higher than those in group A. In group B,serum levels of PRO-BNP,Hcy and ESR were significantly increased with rising cardiac function classification. Serum levels of PRO-BNP,Hcy and ESR in group B were negatively correlated with LVEF,but serum levels of Hcy and ESR were positively correlated with PRO-BNP level. Conclusion Serum levels of PRO-BNP,Hcy and ESR in group A and B are significantly correlated with cardiac function in patients with unstable angina pectoris associated by left ventricular systolic insufficiency,so the levels may be used as important indexes for evaluating the severity and prognosis of with unstable angina pectoris associated by left ventricular systolic insufficiency.

Objective To investigate the effects of mirror visual feedback (MVF) and modified constraint-induced movement therapy (mCIMT) on upper extremity function in post-stroke hemiplegics. Methods 117 patients with hemiplegia post-stroke were collected prospectively from December 2013 to October 2016, and randomly divided into the following four groups: group A (n=30), group B (n=29), group C (n=28) and group D (n=30). All patients were trained with conventional comprehensive rehabilitation therapy for four weeks, while the group B and group C were respectively trained with MVF and mCIMT based on conventional comprehensive rehabilitation therapy. Finally, the group D was simultaneously trained with MVF and mCIMT. The investigation duration was set as four weeks for all groups. The Fugl-Meyer Assessment (FMA) score, Upper Extremity Function Test (UEFT) score, and Modified Barthel Index (MBI) score were used as main index of clinical effects. Results After treatment, the scores of FMA, UEFT and MBI were respectively (26.37±3.44),(43.30±3.46),(56.27±4.76) in group A, (29.17±2.82), (45.41±3.40), (58.72±4.48) in group B, (29.46±3.16), (45.71±2.37), (58.82±3.89) in group C, (31.93±2.74), (48.83±3.57), (62.17±4.51) in group D.Comparing with the scores before treatment, the paired-sample t test showed that there were significant differences (P<0.05). The single factor variance test showed that the scores of the group D were significant better than those scores in group A, group B and group C (P<0.05); furthermore the scores of the group B and group C were significant better than the group A (P<0.05). However, there were no difference at those scores between the group B and group C (P＞0.05). Conclusion Based on conventional comprehensive rehabilitation, single combined with MVF or mCIMT may significantly improve the function of upper limb and activities of daily living (ADL) in post-stroke patients with hemiplegia. However, simultaneous combined with MVF and mCIMT will be more effective than the single one.

Objective We realized that EGF could play an important protective role against NEC. However, the practical condition of the distribution and expression of EGF in intestine of infants with NEC was indefinite. In order to figure out this problem,we carried out this experimentation. Methods The sample were divided into two group.The experimental group(necgroup) were composed of fifteen individual intestinal tissues after the ileostomy were performed on those infants suffered from NEC. The control group(sealing fistula group) were composed of fifteen individual intestinal tissues after the ileal closure fistula were performed on the same infants who were accepted the one-stage ileostomy in the period of NEC and were later accepted the two-stage operation on the condition that their bodies almost recovered from NEC after two to three months gone.Then, we utilized immunohistochemistry to test the distribution and quantities of EGF on those samples of the two group infants. Results The characteristic of EGF expression in intestine of the both group included strong positive expression in mucous layer and less expression in strata submucosum and muscular coat. The average optical density in nec group was mucous layer (0.241±0.075),strata submucosum(0.213±0.026),muscular coat (0.1397±0.022);In the control groupmucous layer (0.211±0.028),strata submucosum (0.119±0.022),muscular coat (0.097±0.007). The expression of EGF in intestinal tissues increased in the period of NEC0.198±0.071 by comparing with the control group (0.146±0.058). Conclusion There may be a correlation between the strong positive expression of EGF in intestinal tissues in the period of NEC and inflammation.By combining the result of this experiment and the research about EGF. We assumed that EGF is one factor of the protective mechanism by which injured intestinal mucous could be recovered and resist inflammation.

Objective To observe and study of functional exercise and psychological nursing for stroke shoulder hand syndrome after the influence of the elderly patients with functional rehabilitation, and the influence on motor function and ability of daily life activities. Methods 60 cases of elderly patients with apoplexy after apoplexy were selected from June 2015 to February 2017. They randomly were divided into two groups: intervention group and control group, each with 30 cases. The intervention group was treated with functional exercise psychological intervention with giving routine treatment and nursing care as the same time. The control group only conducted routine treatment and nursing care. The exercise function was rated by the Fugl-Meyer scoring method (FMA), while the improved Barthel index (MBI) was used to score the daily activities. The anxiety and depression levels were compared between the two groups. Results The FMA score of the intervention group and MBI score were higher than that of the control group, and the difference was statistically significant(P<0.05). The anxiety and depression scores of the intervention group were lower than those in the control group, and the difference between the two groups was statistically significant(P<0.01). Conclusion The functional exercise and psychological care may improve movement function in patients with hemiplegia after stroke, and daily life activities ability, alleviate or eliminate negative emotions, including anxiety depression. It is worth promoting.
