Objective To evaluate the difference of oral sodium phosphate (NaP) and polyethylene glycol-electrolyte lavage solution (PEG-ELS) in the aspects of cleansing efficacy, tolerance, and safety in clinical practice, so as to provide evidence for clinical practice. Methods A systematic review of all the relevant randomized controlled trials (RCTs) was performed according the handbook of the Cochrane Collaboration. RCTs were identified from The Cochrane Library(Issue1,2004) MEDLINE(1980-2004), EMBASE(1984-2004),and CBM(1978-2004).Handsearching was also performed .RCTs comparing the two methods were selected .Tow reviewers independently assessed the quality of included trials and extracted data independently .Results Eighteen trials involving 3668 patients were included .Sub-group analysis was performed. Nap tablet had higher rate of adequate cleansing quality (RR1.08,95%CI1.02 to 1.05,p=0.01).Two-day ,divided-dose oral Nap was superior in the rate of adequate cleansing quality (RR1.27,95%CI1.06 to 1.52,p=0.009). .The. rate of adequate cleansing quality in right colon of Nap was lower than PEG-ELS(RR0.79,95%CI 0.64 to 0.98,p=0.03).The rate of abdominal cramps (RR 0.84,95%CI 0.72 to 0.99),the rate of abdominal fullness (RR 0.48,95%CI 0.26 to 0.89),the rate of nausea (RR 0.65,95%CI 0.56 to 0.76)and the percentage of patients who didn’t finished their prescribed regimen (RR 0.23,95%CI0.14 to 0.36)in Nap group were lower (plt;0.05).Conclusions Compared with PEG-ELS,Nap is superior in cleansing efficacy , patients’ tolerance ,safety and economy . It is possible to promote the use of Nap in clinical practice in China .

Methods : Validation the main performances of selfmade reagent, including accuracy, precision, linear range, stability, and relevance, and carried clinical comparison test with the original reagent kit. Results : The main performances of selfmade reagent achieved the experimental anticipated request. As analyzing the valued serum, the average relative deviations of Na+,K+,Clwere less than 2%; withinrun precision and betweenrun precision were good,coefficient of variations were less than 2%; the selfmade reagent was highly correlated with the original reagent kit,correlation coefficient was greater than 099 Conclusion : Selfmade reagent could substitute the original reagent kit for clinical laboratory.
Safe and effective anticoagulation is the key to successful blood purification. Compared with traditional systemic anticoagulation, regional citrate anticoagulation (RCA) has the advantages of prolonging the life of extracorporeal circulation and reducing bleeding complications. However, the complex protocol, the disorder of electrolyte and acid-base status and the accumulation risk in special populations have dissuaded many clinicians. This review starts with the clinical monitoring of RCA, then analyzes the causes and treatments of complications. The risk assessments in special populations were also introduced in order to the widely promotion of RCA in critically ill patients.
Objective To observe the clinical effect of vitrectomy, inner limiting membrane (ILM) peeling, subretinal injection of compound electrolyte intraocular irrigation solution (CEIIS) and conbercept in the treatment of diabetic macular edema (DME) with hard exudate (HE) (DME-HE). MethodsA prospective clinical study. Thirty-three patients with DME-HE diagnosed by examination in Weifang Eye Hospital from June 2020 to February 2022 were included in the study. Among them, there were 15 males (16 eyes) and 18 females (20 eyes), with the mean age of (62.00±6.54) years. All patients underwent the examinations of best corrected visual acuity (BCVA), scanning laser ophthalmoscope, optical coherence tomography (OCT), and multifocal electroretinography (mf-ERG). Snellen visual acuity chart was used for BCVA examination, which was converted into logarithm of the minimum angle of resolution (logMAR) BCVA for statistic analysis. Macular foveal retinal thickness (CMT) and macular volume (MV) were measured by OCT. The 1 ring P1 wave amplitude density was measured by mf-ERG. The patients were randomly divided into group A and group B, with 17 patients (18 eyes) and 16 patients (18 eyes), respectively. There were no significant differences in age, logMAR BCVA, HE area, CMT, MV, and 1 ring P1 wave amplitude density between the two groups (t=0.403, 0.972, 0.291, 0.023, －0.268, －0.206; P＞0.05). Group A was treated with vitrectomy, ILM peeling, and subretinal injection of CEIIS and conbercept (combined therapy). Group B was treated with intravitreal injection of conbercept (IVC). Follow-up was 12 months after treatment. The changes of BCVA, HE area, CMT, MV, 1 ring P1 wave amplitude density were compared between groups and groups after treatment. The times of injection and complications after treatment were observed. Independent sample t test was used for comparison between the two groups. ResultsAt 12 months after treatment, compared to before treatment, there were significant differences in logMAR BCVA (F=14.837), HE area (χ2=94.522), CMT (χ2=199.212), MV (χ2=81.914) and 1 ring P1 wave amplitude density (F=8.933) in group A (P＜0.05); there were significant differences in CMT (F=5.540) and MV (F=7.836) in group B (P＜0.05). Compared between the two groups, logMAR BCVA: 1 week and 6 and 12 months after treatment, the difference was statistically significant (t=2.231, －2.122, －3.196; P＜0.05); HE area: except 1 week after treatment, there were statistically significant differences at other times after treatment (t=－2.422, －3.107, －3.540, －4.119; P＜0.05). CMT, MV, 1 ring P1 wave amplitude density: 12 months after treatment, the differences were statistically significant (t=－2.653, －2.455, 2.204; P＜0.05). During the follow-up period, the injection times of group A and group B were (3.06±1.89) and (5.56±2.04), respectively, and the difference was statistically significant (t=－3.815, P＜0.05). Macular hole and vitreous hematoma were found in 1 eye in group A and 1 eye in group B. ConclusionVitrectomy, ILM peeling, subretinal injection of CEIIS and conbercept to treat DME-HE can effectively remove HE, alleviate macular edema, improve BCVA, and reduce CMT and MV. Combination therapy can reduce the number of IVC re-treatments.
