Application of hypothermic machine perfusion in the renal transplantation from deceased donor with high-risk delayed graft function / 器官移植

Objective To evaluate the clinical effect of hypothermic machine perfusion (HMP) in the storage of renal grafts from deceased donor (DD) with high-risk delayed graft function (DGF). Methods Clinical data of 52 donors with high-risk DGF were collected in this prospective randomized controlled study. Two renal grafts from each donor were randomly divided into the HMP group (n=52) and static cold storage (SCS) group (n=52). In the HMP group, the renal grafts were stored by LifePort under HMP, whereas the renal grafts in the SCS group were preserved in University of Wisconsin solution (UW solution). The incidence of DGF and primary nonfunction (PNF) after renal transplantation was statistically compared between two groups. The recovery of renal graft function, the survival rates of the recipients and renal grafts within postoperative 1 year were observed in two groups. Results The incidence of DGF in the HMP group was 4%(2/52), significantly lower than 17% (9/52) in the SCS group (P < 0.05). No PNF was reported in the HMP group and 1 case of PND was noted in the SCS group, the difference was not statistically significant (P > 0.05). The recovery time of graft function of the recipients in the HMP and SCS groups were (7.2±0.6) d and (7.7±1.0) d with no statistical significance (P > 0.05). In the HMP group, the urine volume of the recipients on the day of operation, postoperative 1 and2 d was significantly larger than that in the SCS group (all P < 0.05). In the HMP group, the levels of serum creatinine at each time point after operation were significantly lower than those in the SCS group (all P < 0.05). The 1-year survival rates of the recipient and kidney were 98.1%, 92.3% and 100%, 96.2% in the HMP and SCS groups with no statistical significance (all P > 0.05). Conclusions HMP can significantly reduce the incidence of DGF after renal transplantation from DD with high-risk DGF and promote the early recovery of graft function.

A cohort study on body mass index and risk of all-cause mortality among hypertensive population / 中华流行病学杂志

Objective: To investigate the relationship between body mass index (BMI) and all-cause mortality in hypertensive population. Methods: All participants were selected from a prospective cohort study based on a rural population from Henan province, China. Cox proportional hazards regression models were used to estimate the associations of different levels of BMI stratification with all-cause mortality. Restricted cubic spline models were used to detect the dose-response relation. Results: Among the 5 461 hypertensive patients, a total of 31 048.38 person-years follow-up was conducted. The median of follow-up time was 6 years, and 589 deaths occurred during the follow-up period. Compared to normal weight group (18.5 kg/m(2)<BMI<24.0 kg/m(2)) the multivariate-adjusted hazard ratios for all-cause mortality associated with BMI levels (<18.5 kg/m(2), 24-28 kg/m(2), and ≥28 kg/m(2)) were 0.83 (95%CI: 0.37-1.87), 0.81 (95%CI: 0.67-0.97), and 0.72 (95%CI: 0.56-0.91), respectively. The dose-response analysis showed a nonlinear, reverse "S" shaped relationship (non-linearity P<0.001). Conclusion: Overweight or obese might have a protective effect on all-cause mortality in hypertensive population, which supports the "obesity paradox" phenomenon.

Objective: To study changes of ultrastructure of atrial endothelial cells during acute atrial fibrillation (AF) in canines, and explore the possible mechanism of AF left atrial thrombosis. Methods: A total of 16 healthy adult mongrel canines were randomly and equally divided into blank control group (only received thoracotomy without pacing) and rapid atrial pacing (RAP) group (established acute AF model). Myocardial tissue of left and right appendage were taken from two groups and received hematoxylin eosin (HE) staining, then myocardial cell morphological changes was observed under ordinary light microscope; morphological changes of appendage endothelial cells was observed under electron microscope. Results: (1) Paroxysmal AF was successfully induced in all canines of RAP group; (2) There were no significant difference in morphology of appendage and endocardial tissue under ordinary light microscope between two groups; 3. Under transmission electron microscope, endothelium cell of appendage tissue presented defect of different extent, and some shedding in RAP group; while endothelial cell layer was complete with absence of necrosis and shedding in blank control group. Compared with blank control group, there was significant rise in endothelial cell incompleteness (12.5% vs. 75.0%) in RAP group, P=0.041. Conclusion: When acute atrial fibrillation occurs, endothelial cell ultrastructure has already changed, which may be related to thrombosis adhered to wall during atrial fibrillation.

Unilateral continuous spinal anesthesia with hypobaric bupivacaine in elderly patients undergoing hip replacement / 中华麻醉学杂志

Objective To explore the feasibility of using unilateral continuous spinal anesthesia (CSA) in elderly patients undergoing hip replacement.Methods Forty-two ASA Ⅰ-Ⅲ patients (14 males, 28 females) aged 60-93yr were randomized to one of two groups: group 1 unilateral CSA (n = 21) and group 2 continuous epidural anesthesia (CEA,n = 21 ) . The patients in both groups were all premedicated with oral diazepam 5 mg and intramuscular scopolamine 0.3 mg. In group 1 unilateral CSA was performed at L2,3 or 3,4 interspace with the patients in the lateral position with the diseased leg upper most. The patients received a 27 gauge continuous spinal catheter, which was threaded through a 22 gauge spinal needle into subarachnoid space. Hypobaric 0-375% bupivacaine solution (0.75 % bupivacaine: sterile water = 1:1) 0.5-1.0ml was injected. If analgesia did not reach T10 after 5-10 min the same dose was repeated. In group 2 epidural catheter was placed also at L2.3or3,4. A test dose of 3 ml of 2% lidocaine was injected and then a mixture of 2% lidocaine and 0.5% bupivacaine (1:1) 8-10 ml was injected into the epidural space. The level of sensory block and degree of motor blockade were measured and recorded. The intraoperative and postoperative complications associated with spinal or epidural anesthesia were recorded. Results The demographic data, duration of operation and intraoperative blood loss were comparable between the two groups.In group 1 sensory block was confined to the diseased leg and no motor blockade of the healthy leg was observed. MAP was slightly decreased after initial dose of local anesthetics as compared to the baseline MAP in both groups. There was no significant change in SpO2 during operation in both groups. The incidences of hypotension, which needed treatment with intravenous ephedrine and shivering during operation and nausea and vomiting after operation were significantly lower in group 1 than in group 2. Conclusion Unilateral CSA produces satisfactory sensory block with stable hemodynamics and less complications and is anesthesia method of choice in elderly patients undergoing hip replacement.
