Most patients with end-stage renal disease choose maintenance hemodialysis to prolong survival. The clinical application of exercise therapy has a definite effect on maintenance hemodialysis patients, and can effectively improve their quality of life and promote rehabilitation. Individualized exercise therapy under the guidance of medical professionals has positive effects on patients’ physical and mental rehabilitation. This paper mainly summarizes the status of exercise, factors affecting exercise, exercise therapy, exercise and rehabilitation of maintenance hemodialysis patients, and reviews the impact of exercise therapy on the physical and mental health of maintenance hemodialysis patients, in order to provide some references for clinical intervention and prognosis studies.
ObjectiveTo study the clinical characteristics of elderly hemodialysis (HD) patients and discuss how to control their complications, in order to improve their quality of life and lower their mortality rate. MethodContrastive study and analysis were performed on the clinical data of 98 maintenance HD patients (between elderly and young HD patients) between January 2013 and January 2014. Complications, rate of hospitalization and mortality were analyzed during the follow-up of one year. ResultsThe ratio of hypertensive kidney disease and diabetic nephropathy, as primary disease of the elderly HD patients, gradually increased. More people chose to use semi-permanent jugular vein catheter for elderly HD patients. Compared with young HD patients, the levels of hemoglobin, albumin, serum creatinine, KT/v were lower in the elderly patients, and C-reactive protein was much higher (P<0.05). There was no significant difference in cholesterol, triglyceride, calcium, phosphorus, parathormone between the two groups (P>0.05). Dialysis-related hypotension and blocking of vascular access occurred more frequently in elderly HD patients. Hospitalization rate and mortality rate were higher in elderly HD patients (P<0.05). ConclusionsImproving nutritional status, keeping vascular access unobstructed for a long time and decreasing complications related to hemodialysis are helpful for elderly HD patients to enhance their quality of life and reduce the mortality rate.
Objective To investigate the clinical characteristics and mechanisms of ocular manifestations related to carotid artery stenosis. Methods The general clinic data and related ocular manifestations in 124 patients with carotid artery stenosis were retrospectively. Results In the 124 patients, 36 (29%) had ocular manifestations, and 28 (22. 6 %) complained the ocular discomfort as the first symptom. Among the 36 patients, 31 patients (86.1%) had been disclosed unilateral or double stenosis of internal carotid artery by carotid Doppler ultrasound examination, and the result of digital subtract angiography revealed middle and severe degree of internal carotid artery stenosis in 8 and 23 patients respectively. There was no statistic difference of incidence of ocular manifestations between 67 patients of severe internal carotid artery stenosis and 34 patients with middle one（chi;２test,P =0.266 2，P＞0.05). The ocular manifestations included amaurosis fugax (52.8%),acute decline or loss of the visual ability and defect of visual fields (36.1%), binocular diplopia (13.9%), ptosis (13.9%), and persistent high intraocular pressure(2.8%) one patient might had several ocular manifestations simultaneously. In 36 patients, central retinal artery occlusion had been diagnosed in 4, venous stasis retinopathy in 1,central or branch retinal vein occlusion in 6, neovascular glaucoma in 1, and anterior ischemic opticneuropathy in 2. One patient with double occlusion of internal carotid artery didnrsquo;t have any ocular manifestation. Conclusion Carotid artery stenosis, especially internal carotid artery may lead to acute or chronic ocular ischemic lesions, and the occurrence of ocular manifestations in chronic ocular ischemic lesions relates to compensa tion of collateral circulation；patients with ocular ischemic lesions are recomm end to undergo a routine carotid artery examination.

In recent years, Regional citrate anticoagulation (RCA) technology has been widely used not only in adult blood purification, but also in children’s blood purification, and its advantages in patients with high bleeding risk, active bleeding and heparin-induced thrombocytopenia have been repeatedly confirmed. Therefore, this article reviews and analyzes the application of RCA in different blood purification modes at home and abroad in recent years. It is found that its anticoagulation is not only safe and effective, but also can prolong the life of filter and reduce bleeding complications, which is suitable for the practice of blood purification.
Objective To explore the current status of electronic health (eHealth) literacy and online health information seeking behavior of maintenance hemodialysis (MHD) patients, and to explore the relationship between them. Methods MHD patients in the Hemodialysis Center of West China Hospital of Sichuan University between January and April 2022 were selected by convenient sampling method. The patients were investigated with general condition questionnaire, eHealth Literacy Scale and internet health information retrieval behavior questionnaire. According to the score of eHealth literacy, patients were divided into high eHealth literacy group and low eHealth literacy group, to compare the differences between the two groups, and analyze the factors that affected the internet health information retrieval behavior. Results A total of 194 MHD patients were included. Among them, 112 were male and 82 were female. The average score of eHealth literacy was 24.84±9.24. There were 136 cases in low eHealth literacy group, and the average score of eHealth literacy was 20.76±7.91. There were 58 cases in high eHealth literacy group, and the average score of eHealth literacy was 34.36±3.01. Multivariate analysis showed that eHealth literacy and education level were the influencing factors of health information search behavior (P<0.05). Conclusions The overall eHealth literacy of MHD patients is low, and the online health information search means is single and behaviorally inconsistent. It is necessary to improve the eHealth literacy of hemodialysis patients, and at the same time, provide various health information publicity and education for patients with different levels of eHealth literacy, which will help them better carry out disease management.
ObjectivesTo systematically review the efficacy of lidocaine injected prior to tracheal extubation in preventing hemodynamic responses to tracheal extubation in general anesthesia.MethodsPubMed, Ovid, Web of Science, EMbase, The Cochrane Library, CBM, CNKI, VIP and WanFang Data databases were electronically searched to collect randomized controlled trials (RCTs) on the efficacy of lidocaine administrated prior to extubation in preventing hemodynamic responses to tracheal extubation in patients undergoing general anesthesia from inception to October, 2018. Two reviewers independently screened literature, extracted data and assessed risk of bias of included studies, then, meta-analysis was performed by using RevMan 5.3 and Stata 13.0 software.ResultsA total of 10 RCTs involving 525 patients were included. The results of meta-analysis showed that: compared with control group, lidocaine could reduce mean arterial pressure in 5 min after extubation (MD=–5.10, 95%CI –9.41 to –0.79, P=0.02), weaken the increase in systolic blood pressure caused by extubation from the moment before extubation to 5 minutes after extubation (before extubation: MD=–7.22, 95%CI –10.34 to –4.11, P<0.000 01; at extubation: MD=–14.02, 95%CI –19.42 to –8.62, P<0.000 01; 1 minutes after extubation: MD=–15.82, 95%CI –22.20 to –9.45, P<0.000 01; 3 minutes after extubation: MD=–12.55, 95%CI –20.36 to –4.74, P=0.002; and 5 minutes after extubation: MD=–12.05, 95%CI –20.35 to –3.74, P=0.004), and weakened extubation-induced increase in diastolic blood pressure at extubation (MD=–9.71, 95%CI –16.57 to –2.86, P=0.005). In addition, lidocaine inhibited heart rate in all time points except the moment of before and at 10 minutes after extubation.ConclusionsCurrent evidence shows that lidocaine can inhibit the increase in blood pressure and heart rate caused by extubation at certain times. Due to limited quality and quantity of the included studies, more high-quality studies are needed to verify above conclusions.
Objective To explore the effect of xue-shuan-tong(panax notoginsang saponins,PNS)or isovalaemic haemodilution(IHD)and PNS combining IHD treatment on activities of fibrinolysis and hemorrheology in patients with retinal vein occlusion (RVO). Methods Seventy-three patients with RVO were allocated at random to 3 groups which were treated with PNS,IHD and PNS combining IHD.The activities of t-PA and PAI,rheological parameters and visual acuity before and after treatment were observed. Results At the end of treatment,significantly increased activity of t-PA and decrease of PAI was found in combined treatment group and PNS group,but the difference before and after treatment was not significant in IHD group.Furthermore,except the plasma viscosity in IHD group,the other hemorrheological parameters in all the petients of 3 groups revealed to be improving.One month after treatment,the parameters return completely to normal in both PNS and IHD groups; while the whole blood apparent relative viscosity in low shear rate,RBC aggregation and RBC deformability maintained still in lower level,and also the visual acuity resumed better and quicker in combined group. Conclusion Combined treatment of PNS and IHD can both regulate the activity of fibrinolysis and decrease the blood viscosity of patients with RVO for a period of relatively long time and increase the effect of treatment.

Objective To evaluate the efficacy and safety of intermittent hemodialysis (IHD) and continuous renal replacement therapy (CRRT) on patients with acute kidney injury (AKI) after bee sting. Methods A prospective observational analysis was made on patients with AKI after bee sting treated in Jianyang People’s Hospital or West China Hospital of Sichuan University between July 2015 and December 2020. According to different initial renal replacement therapy modes, the patients were divided into IHD group and CRRT group. The IHD group received hemodialysis for 4 hours each time, once a day or 3-5 times a week; the CRRT group used Prismaflex machine for continuous veno-venous hemofiltration or continuous veno-venous hemodiafiltration within 72 hours after admission, for at least 12 hours a day, followed by CRRT or IHD, depending on the patient’s condition. Both groups could be treated with hemoperfusion (HP) and symptomatic support such as glucocorticoid, blood transfusion and fluid rehydration. The IHD group was divided into IHD subgroup and IHD+HP subgroup, and the CRRT group was divided into CRRT subgroup and CRRT+HP subgroup according to whether renal replacement therapy was combined with HP. The basic information of patients and clinical laboratory examination results were collected, and the renal function recovery and mortality rates of patients in the two groups were compared, as well as the changes of laboratory indicators. Results A total of 106 patients were enrolled, 50 in the IHD group and 56 in the CRRT group. There was no statistical difference in the rate of complete renal function recovery 30, 60, or 90 days after treatment between the two groups (28.2% vs. 31.2%, P=0.758; 46.2% vs. 50.0%, P=0.721; 82.1% vs. 81.2%, P=0.924). But in the CRRT subgroup analysis, there was a statistical difference in the 30-day renal function recovery rate of CRRT+HP patients compared with CRRT alone (47.6% vs. 18.5%, P=0.031), while no statistical difference was found in the IHD subgroup analysis. After 3 days of treatment, the levels of creatine kinase of the IHD+HP subgroup and the CRRT+HP subgroup were lower than those in the IHD and CRRT subgroups, and the differences were statistically significant [(7875±6871) vs. (15157±8546) U/L, P=0.026; (10002±8256) vs. (14498±10362) U/L, P=0.032]. There was no statistical difference in 30-day mortality or incidence of serious adverse reactions between the two groups (P>0.05). Conclusions There is no obvious difference in improving renal prognosis or reducing mortality between CRRT and IHD for patients with AKI after bee sting. However, CRRT combined with HP therapy could shorten the recovery time of renal function and increase the 30-day kidney recovery rate. HP may contribute to early renal function recovery in patients with AKI after bee sting, but more high-quality randomized controlled trials are needed to further confirm this.
OBJECTIVE :To investigate ocular vessel flow velocity in normal eyes by color Doppler imaging(CDI). METHODS: Ninety people (180 normal eyes)had flow velocity measured by CDI in three vessels,ophthalmic artery (OA),central retinal artery(CRA) and posterior ciliary artery (PCA),and the relations between velocity and affecting factors were analysed. RESULT: The diastolic and systolic velocity of OA,CRA and PCA were (31.7plusmn;10.9)cm/s, (7.2plusmn;2.6)cm/,s, (10.2plusmn;3.4)cm/s, (2.8plusmn;1.2)cm/s and (11.3plusmn;3.6)cm/s, (3.2plusmn;1.4)cm/s respectively. The velocity of OA had possitive correl-ativity with RBC,HCT and negative correlativity with age,while it revealed no relationship with sex, laterality of right or left eye,and normal IOP. CDI of ocular vessels in normal eyes is a triangle with three peaks and double sunkens in its frenquency spectum, revealed highly resistant,and both the pulsatility and resistive indexes were relatively high. The width of each frequency band basically was the same,and there was no obvious frequency window. CONCLUSION: The ocular application of CDI might lay the foundation of a comparatively comprehensive knowledge of the ocular hemodynamics. （Chin J Ocul Fundus Dis,1997,13: 99-101）
