【Objective】 To explore the effects of early application of erythropoietin (EPO) in patients with anemia after renal transplantation. 【Methods】 Patients who underwent renal transplantation in the First Affiliated Hospital of Soochow University were retrospectively analyzed. According to whether EPO was applied after operation, the patients were divided into EPO group and routine group. Patients with delayed renal function recovery were excluded, and the remaining patients were further analyzed. The general, laboratory and follow-up data of the two groups were compared, and adverse drug reactions were observed. 【Results】 The hemoglobin (P=0.026), red blood cell count (P=0.038) and hematocrit (P=0.011) in EPO group were higher than those in the routine group 2 weeks after operation, while the postoperative serum creatinine level was lower (P=0.001). Since the first week after operation, the reticulocyte count in EPO group was significantly higher than that in routine group (P<0.01). There was a negative correlation between hemoglobin and serum creatinine in EPO group at week 1 (r=-0.375, P=0.010) and week 2 (r=-0.386, P=0.008). During the treatment, 6 patients showed transient elevation of serum potassium, which returned to normal after symptomatic treatment, and no obvious adverse drug reactions were observed. 【Conclusion】 Continuous application of erythropoietin in the early stage after renal transplantation can significantly improve anemia in renal transplant patients and promote the recovery of renal function.

Methods: A systematic literature search was conducted in June 2021 in the PubMed, Embase, Scopus, CINAHL, and Cochrane CENTRAL databases. Clinical and epidemiological studies that reported quantitative data on the prevalence of coexisting LS and KOA were included. Studies which reported data on only LS or KOA alone were excluded. Odds ratios (ORs) and 95% confidence intervals (CI) for LS or KOA were retrieved or calculated for meta-analysis. Fixed-effects and random-effects models were used, and statistical significance was considered when p<0.05. Heterogeneity was evaluated using Cochran’s Q test and the I2 statistic. Risk of bias was assessed using the MINORs (methodological index for nonrandomized studies) criteria. Results: This review included nine studies (5,758 patients). Four studies (4,164 patients) defined KOA and LS by a Kellgren-Lawrence (KL) grade of ≥2 and were included in the meta-analysis. Two other studies defined KOA and LS by a joint space narrowing grade of ≥2. The remaining three studies reported other outcomes. The combined ORs of having KOA of KL grade ≥2 due to LS was 1.75 (95% CI, 1.22–2.50; p=0.002), while the combined OR of having LS of KL grade ≥2 due to KOA was 1.84 (95% CI, 1.23–2.77; p=0.003). Conclusions In patients with either KOA or LS, the odds of having a concurrent knee-spine presentation are significantly increased. This may have implications for clinical decision-making and treatment strategies. Further high-level studies with larger patient populations are required to confirm these results in specific populations.

OBJECTIVES: The integrated model of prenatal diagnosis and postnatal treatment for congenital heart disease (CHD) leads to an increasing number of operation in infants. This study aims to reveal the risk factors for postoperative early mortality and delayed recovery in infants less than 3 months old, who underwent surgical treatment for CHD in the Department of Cardiovascular Surgery, Second Xiangya Hospital, Central South University during the past 5 years. METHODS: Clinical variables were collected via medical records. Delayed recovery was defined as the time of postoperative intubation, or cardiac intensive cure unit (CICU) stay, or hospital stay longer than its third quartile. Risk factors for early postoperative prognosis and the odds ratio (OR) were analyzed with logistic regression analysis. RESULTS: A total of 511 infants underwent surgical treatment for CHD from January 2016 to June 2020 were retrospectively reviewed, including 217 (42.5%) infants with complex CHD. The median age was 60 days (3 hours-90 days); and median weight was 4.5 (1.7- 8.4 kg). There were 26 postoperative mortalities, making the incidence at 5.1%, including 5 (5/294, 0.7%) mortalities in patients with uncomplicated CHD, and 21 (9.6%) mortalities in patients with complex CHD. Based on multivariable analysis, risk factors for postoperative mortality were diagnosis of complex CHD (OR=5.53, P<0.001), weight under 4.0 kg (OR=9.86, P<0.001), preoperative symptoms (OR=3.17, P=0.012), and emergency operation (OR=11.66, P<0.001). The median time for postoperative intubation, CICU stay, and hospital stay were 21.0 (0.3-979.0) hours, 3.0 (0.5-91.0) days, and 11.5 (3.0-105.0) days, respectively. A total of 177 (34.6%) infants delayed recover, with risk factors including diagnosis of complex CHD (OR=3.41, P=0.001), weight under 4.0 kg (OR=4.55, P<0.001), and preoperative symptoms (OR=3.91, P<0.001). CONCLUSIONS Surgical treatment for infants (<3 months) with CHD is still a challenge, particularly for infants with complex CHD and weight under 4.0 kg. We can improve the prognosis of CHD treatment in infants by establishing the integrated model of prenatal diagnosis and postnatal treatment to choose the most suitable time window, avoid symptoms before surgery, and reduce emergency operation.

INTRODUCTIONUp to 20% of patients who underwent total knee arthroplasty (TKA) reported dissatisfaction with surgical outcome. Despite the multiple studies looking into the factors contributing to patients' dissatisfaction, little research has been done to examine the subjective reasons and complaints patients have post-arthroplasty. This study aimed to look at an Asian patient population which underwent TKA and examine the factors contributing to patient dissatisfaction and the reasons they were dissatisfied with their surgery.

MATERIALS AND METHODSA total of 3069 TKAs were performed between January 2011 to April 2013 in a single institution. Preoperative and postoperative variables were prospectively captured, such as standardised knee scores, knee range of motion and patient satisfaction scores. These variables were then analysed with a multiple logistic regression model to determine the statistically significant factors that contribute to patients' satisfaction. Dissatisfied patients were individually interviewed to find the reasons for their unhappiness. Preoperative variables were then analysed to identify the statistically significant factors associated with these subjective complaints.

RESULTSMinimum duration of follow-up was 2 years, with an overall patient satisfaction rate of 91.3%. Preoperative variables contributing to patient dissatisfaction included female gender and better knee flexion. Postoperative variables included lesser improvement in knee flexion at 6 months postoperatively, as well as poorer scores in various validated knee scores at both 6 months and 2 years postoperatively. The top reason for dissatisfaction was pain. Weakness, another reason for patient dissatisfaction, had statistically significant preoperative predictors of increased age and poorer Short-Form 36 Physical Component Score.

CONCLUSIONAlthough TKA has an impressive patient satisfaction rate in this Asian population, factors contributing to postoperative dissatisfaction suggest a targeted group of patients would benefit from preoperative counselling. The top reason for postoperative dissatisfaction in the study was pain.

Objective We evaluate if supplementary grading system can refine patient selection and accurately predict neurological outcome in BAVM. Methods We retrospectively study 221 BAVM patients who were treated micro?surgically by our hospital. The score of pre and post operation mRS and relative clinical, radiology data were collected. Two different logistic models (Spetzler-Martin, Supplementary Spetzler-Martin grading model) were constructed to com?pare the area under ROC. Results Some factors are significant different between worse outcome patients and good out?come patients:Non-hemorrhagic presentations prior surgery, AVM bigger than 3cm, diffuse shape of AVM and the elder patients. Predictive accuracy was higher for the supplementary model (ROC area, 0.91), than the Spetzler-Martin model (ROC area, 0.774). So the predictive accuracy of supplementary model was significantly better than that of the Spet?zler-Martin model (P=0.0362). Conclusions Supplementary Spetzler-Martin model can improve preoperative risk pre?diction and subgroup the patients more efficiently. When the score less than 5(including 5) in supplementary Spet?zler-Martin patients seem to have lower risk relative to surgery.

Objective To investigate the relationship between family burden and support for maintenance hemodialysis ( MHD) patients. Methods Family APGAR index scale ( APGAR scale) and disease family burden scale ( FBS) were used to investigate among 126 MHD patients ( selected by convenient sampling method) from July 2012 to December 2013 in one Beijing level three class A hospital. Results The score of family burden was (36. 01 ± 7. 52) presented at 3 aspects of family economic burden, family daily life and family entertainment activities. The total score of family support was (7. 71 ± 3. 01), in which the good family function was 92 cases (73. 1%), family slightly obstacles 14 cases (11. 1%), and family serious obstacles 20 cases (15. 8%). The burden score of family having MHD patients had negative correlation with the score of family support (r= -0. 426, P<0. 05). Conclusions MHD patients′family support has significant influence on family burden. Therefore, the nursing staffs should strengthen the concept of holistic nursing care, pay more attention to the patients′family burden as well as nursing care, so as to perfect the family function, enhance the family support and comprehensively enhance the quality of care for patients.

BACKGROUNDIt has been argued that the benefits of reducing sodium loading may be offset by increased activation of the renin-angiotensin-aldosterone system (RAAS) and sympathetic nervous system. This study aimed to investigate the long-term effects of an increase in dialysis sodium removal on circulating RAAS and sympathetic system in hypertensive hemodialysis (HD) patients with "normal" post-HD volume status.

METHODSThirty hypertensive HD patients were enrolled in this pilot trial. After one month period of dialysis with standard dialysate sodium of 138 mmol/L, the patients were followed up for a four months period with dialysate sodium set at 136 mmol/L, without changes in instructions regarding dietary sodium control. During the period of study, the dry weight was adjusted monthly under the guidance of bioimpedance spectroscopy to maintain post-HD volume status in a steady state; 44-hour ambulatory blood pressure, plasma renin, angiotensin II (Ang II), aldosterone, and norepinephrine (NE) were measured.

RESULTSAfter four months of HD with low dialysate sodium of 136 mmol/L, 44-hour systolic and diastolic blood pressures (BPs) were significantly lower (-10 and -6 mmHg), in the absence of changes in antihypertensive medications. No significant changes were observed in plasma renin, Ang II, aldosterone, and NE concentrations. The post-HD volume parameters were kept constant.

CONCLUSIONMildly increasing dialysis sodium removal over 4 months can significantly improve BP control and does not activate circulating RAAS and sympathetic nervous system in hypertensive HD patients.

BACKGROUND: Dialysis-related amyloid may occur during long-term dialysis for patients with uraemia, of which the main evocator is β_2-microglobulin (β_22M); therefore, how to eliminate 132M from blood is always the focus of research. OBJECTIVE: To observe ability of removal of β_2-microglobulin (β_2M) from serum using two kinds of polyethersulfone (PES) membrane materials with various degrees of sulfonation.METHODS: These materials were incubated in radio-labeled β_2M (~(125)Ⅰ-β_2M) solution and human serum respectively at appointed time at 37 ℃, and then the amounts of ~(125)Ⅰ-β_2M and serumβ_2M adsorbed by materials were measured by radio immunoassay. RESULTS AND CONCLUSION: In the ~(125)Ⅰ-β_2M system, amounts of ~(125)Ⅰ-β_2M adsorbed by the materials decreased in the following sequence PES with high degree of sulfonation > PES with low degree of sulfonation > PES, whatever the source of PES was. In the serum system, amounts of β_2M adsorbed reached maximums at 30 minutes and the final adsorptions decreased in sequence of PES with high degree of sulfonation > PES with low degree of sulfonaUon > PES. Sulfonated PES removed β_2M more than PES did and the adsorption of β_2M increases with the increase in the degree of sulfonation. Its ability to remove significant amount of β_2M may result in less β_2M available for incorporation into amyloid. The use of sulfonated PES membranes may lessen the likelihood of development of dialysis-related amyloidosis, which remains a major source of morbidity for patients treated with long-term hemodialysis.

ObjectiveToinvestigate the prevalence, awareness and risk factors of chronic kidney disease (CKD) among community adult population in Shanghai, China, in order to provide early diagnosis and treatment of CKD, and informations for national health policy makers.MethodsTwo thousand five hundred and ninety six residents (≥ 18 years old) were randomly selected from community population in Changning district of Shanghai, China. They were interviewed and tested for albuminuria -morning spot urine albumin to creatinine ratio [ACR, abnormal: ≥ 17 mg/g (male), ≥25 mg/g (female)], reduced renal function-estimated GFR by abbreviated MDRD equation [abnormal: <60 ml ·rain-1 (1.73 m2)-1] and hematuria-morning spot urine dipstick confirmed by urine microscopy. The associations among demographic characteristics, healthy characteristics (e.g. diabetes and hypertension) and indicators of kidney damage were examined. The investigators and neighborhood committee were well trained. Those who had semiquantitative positive were detected again by albuminuria-morniag spot urine albumin to creatinine ratio after three months. ResultsTwo thousand five hundred and fifty four residents with complete data were enrolled in the study. Albuminuria was detected in 6.3% of subjects, reduced renal function in 5.8%, hematuria in 1.2%. Approximately 11.8% of these subjects had at least one indicator of kidney damage. The awareness rate of CKD was 8.2%. The Logistic regression model showed that hyperuricemia, nephrolithiasis, anemia, diabetes, central obesity, hypertension and age contributed to the development of CKD. ConclusionsThe prevalence of CKD in community adult population in Shanghai is 11.8%, And the awareness rate of CKD is 8.2%. Hyperuricemia, nephrolithiasis, anemia, diabetes, central obesity, hypertension and age are risk factors of CKD.

The evaluation of the adsorption of methylene blue (MB) in plasma by sulfonated polyethersulfone (SPES) adsorbent column was carried out in this study. The results indicated the adsorption of MB by SPES adsorbent column was more efficient than that by polyethersulfone (PES). In addition, the changes of the concentration of BSA solution passing through adsorbent column along with the time and the biochemical indices of plasma before and after adsorption treatment were also investigated. The results showed that the adsorption amount of BSA by PES adsorbent column was larger than that by SPES, and the biochemical parameters such as total protein, albumin, glucose, triglyceride and total cholesterol in plasma varied slightly before and after passing through the column, which were still within the clinical indices.
