Impact of Intraoperative Plasma Infusion Dose on the Clinical Prognosis of Cardiac Surgery Patients / 中山大学学报(医学科学版)

ObjectiveTo assess the impact of intraoperative plasma infusion dose and coagulation test value INR on the clinical prognosis of patients undergoing cardiac surgery， providing a basis for guiding rational blood use during cardiac surgery. MethodsThe clinical data of 305 surgical patients who received fresh frozen plasma transfusion during cardiac surgery were collected in Sun Yat-sen Memorial Hospital of Sun Yat-sen University from January 2014 to December 2022. The patients were divided into low-dose group （plasma infusion dose <15 mL/kg， n = 214） and high-dose group （plasma infusion dose ≥15 mL/kg， n = 91） based on the intraoperative plasma dose. Univariate analysis， correlation analysis and logistic multivariate regression analysis were used to analyze the relationship between plasma infusion dose， changes in INR before and after plasma transfusion， and the clinical prognosis of patients undergoing cardiac surgery. ResultsThe median plasma infusion dose for all patients was 11.11 （8.17-19.05） mL/kg， while the median plasma infusion dose in the high-dose group and the low-dose group was 17.78 （15.69-20.91） mL/kg and 9.52 （7.77-11.43） mL/kg， respectively， with a statistically significant difference （P <0.001）. The median INR decrease in the high-dose and low-dose groups was 0.98 （0.60-1.26） and 0.50 （0.35-0.76）， respectively， with a statistically significant difference （P<0.001）. Logistic multivariate regression analysis revealed that abnormally elevated preoperative INR values increased the risk of postoperative red blood cell transfusion within 24 hours in cardiac surgery patients （P<0.001）， with an OR 95%CI of 6.757（3.068， 14.822）. Additionally， it also increased the risk of postoperative in-hospital mortality （P< 0.001）， with an OR 95%CI of 5.441 （2.193， 13.499）. INR decrease reduced the risk of postoperative red blood cell transfusion within 24 hours in cardiac surgery patients （P=0.001）， with an OR 95%CI of 0.244（0.107， 0.558）. Correlation analysis showed positive correlation between plasma infusion dose and postoperative ICU days （rs=0.569， P<0.001） and hospital days （rs=0.302， P<0.001） in cardiac surgery patients. ConclusionAmong patients undergoing cardiac surgery who receive intraoperative plasma transfusion， high plasma infusion dose and abnormally elevated preoperative INR values are associated with poorer clinical outcomes， while patients who show a greater degree of INR correction after plasma transfusion exhibit better clinical results.

Effect of high intraoperative plasma dose on the prognosis of patients undergoing blood transfusion during perioperative period / 中国输血杂志

【Objective】 To explore the relationship between the intraoperative plasma transfusion volume, the changes of blood coagulation test values and the clinical prognosis of surgical patients, so as to provide a theoretical basis for guiding the rational use of blood during the operation. 【Methods】 The clinical data of 556 surgical patients who received plasma infusion from January 2017 to December 2020 in Sun Yat-sen Memorial Hospital were collected. Patients were divided into low plasma dose group (<15 mL/kg) and high plasma dose group (≥15 mL/kg). The univariate regression analysis, logistic multivariate regression analysis and linear regression analysis were used to explore the relationship of plasma dose, the changes of coagulation indicators and the clinical prognosis. 【Results】 A total of 556 surgical patients were included in the study and the median (interquartile range) of plasma transfusion volume for all patients during the operation was 10.5 (8.5~14.0) mL/kg. In multivariate regression analysis, an increase of 1 mL/kg of intraoperative plasma dose resulted in an increased risk of red blood cell infusion within 24 hours after surgery[OR(95% CI) 1.16(1.01, 1.33), P<0.05], an increase in the ICU stays[Mean(95%CI) 0.19(0.03, 0.35), P<0.05] and an increase in the hospitalization days[Mean(95%CI) 0.55(0.27, 0.81), P<0.05]. The preoperative INR value increased the risk of red blood cell infusion within 24 hours after surgery[OR(95% CI) 1.82(1.33, 2.50), P<0.05], and increased the hospital mortality of postoperative patients[OR (95% CI) 2.15 (1.09, 4.24), P<0.05]; the decrease in INR reduced the risk of red blood cell infusion in patients 24 hours after surgery[OR(95% CI) 0.47(0.27, 0.84), P<0.05]and reduced hospital mortality[OR(95% CI) 0.23(0.13, 0.50), P<0.05]. 【Conclusion】 In surgical patients undergoing intraoperative plasma infusion, abnormal preoperative INR value and high intraoperative plasma infusion are related to poor clinical prognosis, while INR decrease (preoperative-postoperative) was related to better clinical results.

Effect of Intestinal Microecology on Diabetic Kidney Disease Based on Yin-Yang Theory / 中国实验方剂学杂志

Diabetic kidney disease （DKD） is the main cause of end-stage renal disease. Its high prevalence， mortality rate， and medical cost bring a heavy economic burden to society and families， and DKD has become one of the most important public health problems. Intestinal microecology is the most important and complex micro-ecosystem in the human body， which is involved in important life activities such as material and energy metabolism， immune system regulation， and signal transduction， thereby maintaining the dynamic balance of the human internal environment. The dynamic balance between the intestinal microecology and the body is essentially a Yin-Yang balance. Once this balance is broken， intestinal microbiota imbalance， intestinal mucosal barrier damage， immune dysfunction， and reduction of metabolite short-chain fatty acids （SCFAs） will occur， which play an important role in the progression of DKD. From the perspective of the Yin-Yang theory of traditional Chinese medicine （TCM）， the imbalance of intestinal microecology in DKD is equivalent to the excessive or insufficient constraint of Yin and Yang， or Yin deficiency affecting Yang， or Yang deficiency affecting Yin， or waning and waxing of Yin and Yang. For different pathogenesis changes， "Yin disease treated through Yang"， "treating Yin for Yang"， or "treating Yang for Yin" methods are adopted to regulate intestinal microbiota， inhibit immune inflammation， protect intestinal mucosal barrier， and increase SCFAs through TCM， thereby reconciling Yin and Yang to achieve the condition where "Yin is at peace and Yang is compact". Based on the Yin-Yang theory， this paper intended to interpret the scientific connotation of TCM in the treatment of DKD with intestinal microecology as the target and TCM in the treatment of DKD by regulating intestinal microecology as the breakthrough point to provide a novel insight for the occurrence and development of DKD and the mechanism of TCM.

Blood consumption and clinical prognosis in patients with massive blood transfusion: a retrospective analysis / 中国输血杂志

【Objective】 To investigate the incidence of clinical massive blood transfusion in hospitals, the proportion of departments conducted massive blood transfusion and the current situation of component transfusion, so as to provide a theoretical basis for medical decision-making and further research on massive blood transfusion. 【Methods】 The basic clinical data and transfusion of blood components were retrospectively collected from 489 patients (514 occasions) who received massive blood transfusion at Sun Yat-sen Memorial Hospital of Sun Yat-sen University from Jan. 1 2014 to Dec. 31 2018. 【Results】 The incidence of massive blood transfusion during the 5-year period was 1.2/1 000 inpatients (95%CI: 1.1-1.3), and the 30-day all-cause mortality was 21.88%; in the departments where massive blood transfusion occurred, the mortality rate was the highest in the trauma emergency department (60%), followed by intensive care unit (56.25%) and other surgery department (46.67%), while there was no death in the obstetric department. All patients received red blood cells [median 14 U (11.5-19.13)] and plasma [median 1 600 mL (1 200-2 200)], of which 47% received platelet [median 0 U (0-10)] and 32.68% received cryoprecipitate [0 U (0-10)]. The results of logistics regression analysis of all-cause mortality risk showed that compared with the youth group, the risk of all-cause death at 30 days of elderly patients over 65 years old (65 80 years old: OR=7.563, 95%CI=[1.587, 36.049], P<0.05) and 24-hour RBC infusion volume greater than 18 U (18≤RBC<27: OR=2.948 95%CI=[1.592, 5.462], P<0.05; RBC≥28: OR=3.992, 95%CI=[1.178, 13.536], P<0.05) was higher. 【Conclusion】 A dynamic definition should be included in massive transfusion studies. If only a 24-hour RBC infusion volume ≥18 U was used as the mass transfusion definition, about 68% of cases would be lost. The mortality rate of patients with massive blood transfusion was higher, and the incidence of massive blood transfusion was higher in the departments of cardiac surgery, general surgery and orthopedics surgery. More attention should be paid to the increasing number of female patients with massive blood transfusion. In addition, the risk of 30-day all-cause death was highest in elderly patients over 65 years of age and those with a 24-hour erythrocyte transfusion level of ≥18 U.

New progress of mechanism of action of miRNA-21 in diabetic kidney disease and Chinese medicine intervention / 天津医药

Diabetic kidney disease is one of the complications of diabetes,which can progress to end-stage renal disease.In recent years,it has been found that miRNAs have become a research hotspot,with miRNA-21 regulating transforming growth factor β1(TGF-β1)/Smads,phosphoinositide 3-kinase(PI3K)/protein kinase B(AKT),Wnt/β-catenin and other signaling pathways to promote the progress of diabetic kidney disease.Studies have showed that traditional Chinese medicine has a regulatory effect on the expression of miRNA-21 and can target miRNA-21 to regulate TGF-β1/Smads,phosphatase and tensin homolog/PI3K/AKT/mammalian target of rapamycin(mTOR),peroxisome proliferator activated receptors and other signal transduction pathways to trigger signal cascade reactions,which intervene in pathological processes such as fibrosis,inflammation,oxidative stress and autophagy.In this article,the role of miRNA-21 in diabetic kidney disease and the intervention of traditional Chinese medicine were summarized,in order to provide some reference for the treatment of diabetic kidney disease and the development of new drugs.

Hyperuricemic Nephropathy in Traditional Chinese Medicine and Integrated Traditional Chinese and Western Medicine： A Review / 中国实验方剂学杂志

Hyperuricemic nephropathy （HN）， a secondary renal damage common in clinical practice， is characterized by early concealing and continuous progression. The understanding of HN in traditional Chinese medicine （TCM） is from a macroscopic perspective. According to the TCM theory， HN is caused by the combination of external pathogens and internal injuries， with the main pathogenesis being root deficiency combined with superficial excess and deficiency-excess in complexity. In western medicine， the understanding of HN is from the microscopic perspective， which holds that the occurrence of HN is the result of inflammation， oxidative stress， renin-angiotensin-aldosterone system （RAAS） activation， and metabolic abnormalities. The TCM syndromes of HN include internal dampness and heat， obstruction in dampness and turbidity， deficiency of spleen and kidney， and deficiency of kidney yin. Accordingly， the prescriptions should clear heat and dampness， remove dampness and turbidity， tonify spleen and kidney， and nourish kidney yin， respectively. In addition to TCM prescriptions， single herbal medicines and their extracts， Chinese patent medicines， and external applications of Chinese medicines have played a significant role in the treatment of HN， promoting the application of TCM in the treatment of HN. Moreover， the integrated traditional Chinese and western medicine has also played a role in the treatment of HN， enriching the treatment schemes of HN. Different from common kidney diseases such as acute and chronic glomerulonephritis and nephrotic syndrome， HN with particularity should be carefully differentiated in clinical practice. This article systematically summarizes the research progress in the treatment of traditional Chinese medicine and integrated traditional Chinese and western medicine on hyperuricemic nephropathy with TCM and integrated traditional Chinese and western medicine， aiming to enrich the system and theory of HN treatment and further guide the clinical practice.

Analysis of the influencing factors of cardiopulmonary bypass with ultra-fast-track anesthesia in pediatric heart surgery / 中华胸心血管外科杂志

Objective:Analyze the perioperative data of children undergoing cardiopulmonary bypass(CPB) for congenital heart disease under the management of ultra-fast track anesthesia(UFTA), the factors of CPB are discussed.Methods:1 034 children who underwent CPB from May 2018 to August 2019 were analyzed retrospectively. According to the success of anesthesia, they were divided into two groups: UFTA group and UFTA failure group. Propensity score matching was used to screen the children with preoperative baseline data matching. Finally 346 cases in each group. The possible CPB factors of the two groups were analyzed by single factor analysis, and the statistically significant factors were analyzed by logistic regression analysis. Results:Univariate analysis showed that the CPB and aortic occlusion time, the lowest temperature and lowest hematocrit in CPB, the dosage of crystalloid and suspended erythrocytes, the second or more times of CPB, and the blood lactate after CPB were the factors influencing the ultra-fast track anesthesia. Logistic regression analysis showed that the time of CPB and aortic occlusion, the value of blood lactate, the dosage of suspended erythrocytes, and the second or more times of CPB were the independent influencing factors of ultra-fast track anesthesia. In the UFTA failure group, the postoperative hospitalization time, the length of stay in the ICU and the hospitalization cost were all higher than those in the ultra-fast track group. Conclusion:CPB time, aortic occlusion time, blood lactate after CPB, the dosage of suspended erythrocytes, secondary or multiple CPB were independent risk factors for UFTA.UFTA is beneficial to shorten the postoperative hospital stay, the ICU stay and the cost of hospitalization.

Satellite effusion sign: an important CT sign of epidural hematoma / 中华神经医学杂志

Objective:To investigate the CT imaging features of epidural hematoma (EDH) surrounding subdural effusion (satellite effusion sign) and its application value in diagnosis of EDH.Methods:A retrospective analysis of clinical and imaging data of 30 patients with EDH and 122 patients with acute subdural hematoma (SDH), admitted to our hospitals from December 2017 to February 2020, was performed. The frequencies of satellite effusion sign were compared in the two groups, and the differences between the correct diagnosis rate of traditional CT performance and the correct diagnosis rate of traditional CT performance+satellite effusion sign were compared in the two groups; the specific characteristics of satellite effusion sign was clarified and its relations with morphological characteristics and distribution of hematoma were analyzed.Results:Among 30 patients with acute EDH, the occurrence rate of satellite effusion sign was 63.3% (19/30); among 122 patients with acute SDH, the occurrence rate of satellite effusion sign was 2.5% (3/122); the difference was statistically significant ( χ2=67.248, P=0.000). Among the 30 patients with acute EDH, the correct diagnosis rate of traditional CT manifestation was 86.7% (26/30), and the correct diagnosis rate of traditional CT manifestation+satellite effusion sign was 93.3% (28/30), without statistically significance ( χ2=0.185, P=0.667). The length of the satellite effusion sign was (1.1±0.9) cm, ranged from 0.2 cm-3.1 cm; the width was (3.6±2.0) mm, ranged from 1.4 mm-7.5 mm. The incidence of satellite effusion sign in the frontotemporal EDH patients (73.9%) was significantly increased as compared with that in the occipitoparietal EDH patients (28.6%, P<0.05); that of patients with clinically diagnosed cerebral contusion, laceration, cerebral hernia or other severe to extremely severe craniocerebral injuries (22.2%) was significantly reduced as compared with that of patients with mild to moderate craniocerebral injuries (81.0%, P<0.05). Conclusion:Satellite effusion sign is an important new CT sign in the diagnosis of EDH, which is closely related to the locations of hematoma and severities of craniocerebral injury.

Congenital diaphragmatic hernia: perioperative management of 4 cases on extracorporeal membrane oxygenation / 中国新生儿科杂志

Objective To summarize the experience of perioperative management for repair of congenital diaphragmatic hernia (CDH) supported by extracorporeal membrane oxygenation (ECMO). Method Retrospective review was conducted for the clinical data of CDH patients who received surgical repair on ECMO from December 2016 to June 2018 in Guangzhou Women and Children's Medical Center. Result Four fetus with prenatal diagnosis of left-side CDH were transferred to our Center and received standardized perinatal management. Moderate-severe pulmonary hypoplasia was recognized after evaluation by fetal imaging. Four cases were initiated with veno-arterial ECMO at 3, 35, 41, 11 h of life, respectively. Repair of the diaphragmatic defect was performed within two weeks after cannulation of ECMO. Furthermore, activated clotting time goals were adjusted to 180～220 s, activated partial thromboplastin time were stabilized between 50～80 s, platelets count were maintained>100×109/L and hematocrit was kept>30％before the surgery. The surgeries of four patients were completed on the 0.9th, 0.5th, 3.6th, 5.1th day of life on ECMO, respectively. The defect was repaired by parachute patch. The operative time was 85～210 min. According to CDH Staging System defect size (A to D), there were two with defects at grade C and other two at grade D. Postoperative total volume of drainage was 215～1301 ml and ECMO duration was 3.0～39.3 d. Three of them survived during neonatal period, while one died. Conclusion Repair of CDH on ECMO is feasible and help to improve neonatal survival, especially for those with moderate-severe pulmonary hypoplasia.

Improving outcomes of patients with heterotaxy and functional single ventricle: a 10-year follow-up of 70 cases in a single institution / 中华外科杂志

Objective@#To review current-era palliation outcomes of patients with heterotaxy and functional single ventricle in a single institution.@*Methods@#The clinical data of 70 consecutive patients with heterotaxy undergoing multistage single ventricle palliation in Guangzhou Women and Children′s Medical Center from January 2008 to December 2017 were retrospectively reviewed, and the prognosis factors for mortality were analyzed. There were 53 male and 17 female patients.The median age was 13.3 months (range: 6 days to 150 months). Single ventricle multistage palliation included 1st stage palliation surgery, 2nd bidirectional Glenn shunt, and 3rd stage modified Fontan.The Kaplan-Meier method was used to estimate the probability of survival. Multivariate analysis was performed by Cox regression model.@*Results@#Sixty-two patients had right atrial isomerism while eight had left atrial isomerism. Eighteen patients (25.7%) required the first stage palliation. Fifty-five patients received the Glenn shunt, and the Fontan procedure was completed in 27 patients. Overall, mortality occurred in 17 patients (24.3%) including 9 after the first stage palliation, 6 after the Glenn shunt, and 2 following the Fontan procedure. Survival estimates for the entire cohort following surgery were 81% (95%CI: 72% to 90%), 74%(95%CI: 64% to 85%), and 74% (95%CI: 64% to 85%) at 1 year, 5 years and 10 years, respectively. Survival estimates following the first stage palliation were 56% (95%CI: 33% to 79%) and 49% (95%CI: 26% to 73%) at 1 year and 5 years, respectively. Multivariate Cox regression analysis revealed that total anomalous pulmonary venous connection (TAPVC) (HR=6.16, 95%CI: 1.65 to 22.95, P=0.007), atrioventricular valve regurgitation more than moderate (HR=3.81, 95%CI: 1.32 to 10.94, P=0.013) and required the first palliation surgery (HR=4.58, 95%CI: 1.34 to 15.72, P=0.016) were prognosis factors for overall mortality.@*Conclusions@#The management of heterotaxy patients with functional single ventricle remains challenging, and the outcomes are continously improving in china. TAPVC, atrioventricular valve regurgitation more than moderate and required the first palliation surgery still are prognosis factors for overall mortality in heterotaxy syndrome.

Study on the Mechanism of Histone Deacetylase Inhibitor RGFP109 in Reversing Resistance of Glioma U251 Cells to Temozolomide / 中国药房

OBJECTIVE:To study the mechanism of histone deacetylase inhibitor RGFP109 in reversing resistance of glioma U251 cells. METHODS:TR/U251 cells resistance to temozolomide(TMZ)was extrablished. The test was divided into normal con-trol group,TMZ group(40 μmol/L)and TMZ(40 μmol/L)+RGFP109(0-120 μmol/L)different concentrations groups. After 24 h of adding into related medicines,CCK-8 was used to detect the cell survival rate and calculate the half inhibitory concentration (IC50). TUNEL and Annexin V/PI were used to detect the cell apoptosis in normal control group,TMZ group and TMZ+RGFP109 (42μmol/L)group. Immunoblotting was used to detect the O6-methyl guanine-DNA methyltransferase(MGMT),Survivin,B lym-phoma 2(Bcl-2),B lymphoma xL(Bcl-xL)protein expression;and gel migration test was used to detect the p65 acetylation level and its binding capacity with κB-DNA. RESULTS:Compared with normal control group,cell survival rate in TMZ+RGFP109 dif-ferent concentrations groups was obviously decreased (P<0.05),showing a concentration-dependent manner. When the RGFP109 concentration was 42 μmol/L,the sensitivity of TMZ to TR/U251 cells was the same with U251 cells. Compared with normal con-trol group,MGMT,Survivin,Bcl-2,Bcl-xL protein expressions in cells of TMZ groups were enhanced(P<0.01);p65 acetyla-tion level had no obvious changes,while the binding capacity of p65 and κB-DNA was strengthened (P<0.01). Compared with TMZ group,MGMT,Survivin,Bcl-2,Bcl-xL protein expressions in cells of TMZ groups were weakened(P<0.01);p65 acetyla-tion level was enhanced (P<0.01);and the binding capacity of p65 and κB-DNA was weakened (P<0.01). CONCLUSIONS:RGFP109 can reverse the resistance of U251 cells to TMZ by down-regulating the anti-apoptotic protein expressions adjusted by transcription factorκB(NF-κB)and weakening the binding of p65 andκB-DNA.

Objective To investigate the protection effects and possible mechanism of apoptotic effect of compound Xiancao granules on renal ischemia reperfusion injury ( IRI ) in rats. Methods Renal IRI rat model was established by clipping bilateral renal artery.The rats were divided into model control group (n=10), compound Xiancao granules group (n=10) and sham operation group (n=10).All Serum creatinine (Cr) and blood urea nitrogen (BUN) were determined to evaluate kidney function after IRI.Superoxide dismutase (SOD), glutathione peroxidase (GSH-PX) and malondialdehyde (MDA) activity in kidney were measured by colorimetric method. Expression of apoptotic regulatory genes Bcl-2 and Bax in renal tissue were detected by Western blotting.Renal tissue sections were stained by hematoxylin and eosin (HE) and examined under a light microscope. Results SOD and GSH-PX levels of the compound Xiancao granules group (278.1±16.2),(155.96±20.58) U?mg-1 were significantly higher than those of the model control group (196.3±12.1),(109.34±17.81) U?mg-1 (P<0.05). MDA, BUN and Cr (12.49±1.07) nmol?mL-1,(8.9±2.7) mmol?L-1,(149.7±8.5) μmol?L-1 were significantly reduced in the compound Xiancao granules group as compared with those of the model control group (17.32±1.26) nmol?mL-1,(14.6± 3.3) mmol?L-1,(206.1±11.2) μmol?L-1(P<0.05).Bax and Bcl-2 mRNA expression levels of sham operation group were significantly lower, and the Bax and Bcl-2 mRNA expression levels of model control group were significantly enhanced ( Bcl-2:P<0. 05, Bax: P<0. 01 ) . Bax mRNA expression level of compound Xiancao granules group was significantly decreased as compared with that of model control group ( P<0.05) , but Bcl-2 mRNA expression level of compound Xiancao granules group was significantly enhanced as compared with that of model control group (P<0.01). Conclusion These results suggested that compound Xiancao granules has protection effect on renal IRI in rats. The mechanisms may be related to its antioxidant activity and expression of the apoptotic genes such as Bcl-2 and Bax.

Objective To explore the outcomes and complications of 111 patients with pituitary neoplasms after neuroendoscopic endonasal transsphenoidal surgeries.Methods A retrospective review of clinical and radiographic data of 111 patients (113 procedures),admitted to our hospital from June 2010 to July 2014,was performed.The resection rate,clinical cured rate and complications in pituitary neoplasms of different Knosp classifications were compared.Results Gross total resection (GTR) rate for pituitary neoplasms according to Knosp classification was 97.4％ in grade 0,85.7％ in grade 1,88.7％ in grade 2,51.9％ in grade 3 and 0％ in grade 4,with significant differences (P＜0.05);GTR rate in pituitary neoplasms of grade 3 and 4 was significantly lower than that in pituitary neoplasms of grade 1 and 2 (P＜0.05).Clinical cured rate of the prolactin adenomas of different Knosp grades was significantly different,and that of grade 0 was statistically higher than that of grade 1-4 (P＜0.05).Clinical cured rate of growth hormone adenoma,adeno-corticotrophic stimulating hormone adenoma and mixed-functional adenomas of different grades showed no significant differences (P＞0.05).Chief complaints were improved in 75.0％-91.7％ non-functioning adenomas.Postoperative severe complications included 3 patients (2.7％) with cerebrospinal fluid rhinorrhea,4 (3.5％) intracranial hematoma,1 (0.9％);postoperative mild complications included 3 (2.7％) epistaxis,14 (12.4％) transient diabete insipidus,1 (0.9％) permanent diabetes insipidus and 3 (2.7％) hyponatremia.Mortality was observed in one patient with intracranial hematoma.Conclusions Neurendoscope provides a superior view of the sellar region,and improves the extent of resection of pituitary adenoma especially for those with cavernous sinus invasion;however,blind pursuit of GTR for tumor with Knosp classification greater than grade 3 will increase the risk of severe complications.Safety should always be the priority for a procedure with a long learning curve like neuroendoscopic surgery.Remission of residue tumor can be addressed by subsequent radiotherapy/stereotactic surgery.

Comparison of High Volume Zero-Balanced Ultrafiltration With Different Replacement Fluid in Infant Patients / 中国循环杂志

Objective:To compare the clinical effects of high volume zero-balanced ultraifltration (ZBUF) with different replacement lfuid in infant patients. Methods: A total of 40 infant patients who received aortic coarctation with deep hypothermic circulatory arrest operation in our hospital from 2012-11 to 2014-02 were summarized. The patients were randomized into 2 groups, Group A, the patients had ZBUF with plasmalyte A, n=21 and Group B, the patients had ZBUF with modiifed replacement lfuid n=19. All patients received ZBUF (15-20) ml/kg during re-warming period until the temperature reached 34°C at rectum. Blood gas analysis were conducted at 4 time points as T1 (before CPB), T2 (open ascending aorta and 5 min after calcium perfusion), T3 (ifnishing ZBUF) and T4 (end of CPB). The intra-operative CPB time and the post-operative recovery with the complication were recorded in all patients. Results: For blood gas analysis, the calcium concentration was higher in Group B than that in Group A at T3 time point, P0.05. The other indexes were similar between 2 groups, P>0.05 and the post-operative recovery was similar between 2 groups, P>0.05. Conclusion: ZBUF with modiifed replacement lfuid could avoid decreased calcium concentration and acidosis, therefore, provide a relative stable homeostasis in infant patients.

Effect of early continuous renal replacement therapy on patients with severe sepsis / 中国中西医结合急救杂志

Objective To evaluate the effect of early continuous renal replacement therapy(CRRT)on patients with acute kidney injury(AKI)induced by severe sepsis. Methods A prospective study was conducted. 160 patients with AKI induced by severe sepsis admitted to intensive care unit(ICU)of Qingyuan People's Hospital between October 2009 and June 2013 were enrolled. According to the starting time of CRRT,the patients were randomly divided into two groups:an earl y treatment group and a regular treatment group(each,80 cases). All patients were treated in accordance with the principle of the cluster of severe sepsis. In early treatment group,the patents began to receive CRRT when the amount of urine output was0.05). Early treatment group and regular treatment groups of creatinine recovery time were similar(day:5.1±1.3 vs. 5.2±1.2). 28-day survival rate in early treatment group was higher than that in regular treatment group(41.2%vs. 35.0%),but there was no statistically significant difference(P>0.05). Conclusion It is found that there is no evidence to suggest that early CRRT may improve the prognosis of the patients with AKI induced by severe sepsis,but it may be in favor of shortening the time of urine recovery,length of stay in ICU,length of organ support and length of dialysis.
