ABSTRACT
Diabetic nephropathy （DN） is a common clinical complication of diabetes， the main cause of end-stage renal disease （ESRD）， and a key determinant of survival in diabetic patients. The pathogenesis of DN is complex， and it is currently believed to be associated with hemodynamic abnormalities， intestinal flora disturbances， glucose and lipid metabolism disorders， oxidative stress， genetic susceptibility， and protein non-enzymatic glycosylation. The local renin-angiotensin system （RAS） has always been the core of the pathogenic and progressive changes of DN. Once activated， it will induce the massive release of oxygen free radicals in the blood vessels， damage the endothelial function， and affect the microcirculation of the body. The recent studies demonstrate that intestinal flora and its metabolites may affect the occurrence and development of DN by activating or antagonizing the local RAS. Compared with western medicine treatment， traditional Chinese medicine （TCM） has the advantages of multiple targets and little toxic and side effects. Many TCM scholars have found that single herbs， their active ingredient extracts， and TCM compound prescriptions can improve kidney function by regulating the local RAS or intestinal flora. Specifically， the Chinese medicinal materials tonifying spleen （Codonopsis Radix， Dioscoreae Rhizoma， Atractylodis Macrocephalae Rhizoma， and Poria）， replenishing kidney （Rehmanniae Radix Praeparata， Corni Fructus， and Pseudostellariae Radix）， and activating blood， resolving stasis， and dredging collaterals （Hirudo， Salviae Miltiorrhizae Radix et Rhizoma， and Angelicae Sinensis Radix） have the regulatory effect. This article summarizes the roles of intestinal flora and local RAS in the occurrence and development of DN， and analyzes the animal experiments or clinical trials of TCM intervention in DN in recent years， aiming to provide more therapies and a theoretical basis for the treatment of DN with integrated TCM and Western medicine.
ABSTRACT
Objective:To explore the effect of enhanced recovery after surgery (ERAS) protocols in patients undergoing laparoscopic radical cystectomy (LRC) and intracorporeal urinary diversion (ICUD).Methods:A total of 83 patients who received LRC+ ICUD in Beijing Chaoyang Hospital from March 2014 to September 2020, were divided into 2 groups based on different perioperative management, including 29 ERAS cases and 54 conventional recovery after surgery (CRAS) cases. The ERAS group included 26 males and 3 females , with an average age of (62.07 ± 9.26) years. There were 26 patients with ASA class Ⅰ-Ⅱ, 3 patients with ASA class Ⅲ, 4 patients received neoadjuvant chemotherapy, and 7 patients had a history of abdominal surgery in ERAS group. The CRAS group included 44 males and 10 females , with an average age of (61.59 ± 10.16) years. There were 50 patients with ASA class Ⅰ-Ⅱ, 4 patients with ASA class Ⅲ, 9 patients received neoadjuvant chemotherapy, and 10 patients had a history of abdominal surgery in CRAS group. There were no statistically significant differences in the baseline characteristics between the two groups. The patients in both groups underwent LRC+ ICUD procedures. The perioperative results and complications between the two groups were compared.Results:In the ERAS group, there were 20 patients who underwent Bricker ileal conduit surgery and 9 patients who underwent Studer orthotopic ileal neobladder surgery. Pathological staging included 3, 3, 7, 7, 5 and 4 cases in stage T a, T is, T 1, T 2, T 3 and T 4a, respectively. There were 23, 2, 3 and 1 patient with pathological stage N 0, N 1, N 2 and N 3, respectively. Pathological diagnosis included 3 cases of low-grade urothelial carcinoma, 24 cases of high-grade urothelial carcinoma, and 2 cases of other histological subtypes. In the CRAS group, there were 31 patients who underwent Bricker ileal conduit surgery and 23 patients who underwent Studer orthotopic ileal neobladder surgery. Pathological staging included 5, 3, 12, 9, 15 and 10 patients in stage T a, T is, T 1, T 2, T 3 and T 4a, respectively. There were 35, 6, 7 and 6 patients with pathological stage N 0, N 1, N 2, and N 3, respectively. Pathological diagnoses included 6 cases of low-grade urothelial carcinoma, 45 cases of high-grade urothelial carcinoma, and 3 cases of other histological subtypes. There were no statistically significant differences ( P>0.05) in surgical methods, pathological staging, or pathological types between the ERAS and CRAS groups. ERAS group presented less albumin loss [(25.73±8.63)% vs. (32.63±9.05)%, P=0.001], shorter hospital stay [9(7, 13)d vs. 12(9, 16)d, P=0.006], less 30-day overall complications [55.2% (16/29) vs. 83.3% (45/54), P=0.009]. In multivariable analysis, maximum albumin loss≥20% was independently associated with 30-day minor complications ( P=0.049), and maximum albumin loss ≥25% was independently associated with hospital of stay≥10 days ( P=0.038), respectively. Conclusions:For patients who received LRC+ ICUD, ERAS was associated with reduced perioperative albumin loss, shorter length of stay, less 30-day complications, accelerated recovery time, improved clinical outcome and less albumin injection.
ABSTRACT
Objective To explore the perioperative outcomes and safety of enhanced recovery after surgery (ERAS) in laparoscopic radical cystectomy (LRC).Methods We retrospectively evaluated outcome of 10 LRC patients on ERAS protocol from May 2017 to October 2017,and 39 LRC patients on conventional recovery after surgery(CRAS) protocol from July 2015 to November 2016.There were (60.9 ±11.4) years and (63.7 ± 12.1) years in ERAS group and CRAS group respectively(P =0.514);(25.5 ±2.7) kg/m2 and (24.4 ± 3.6) kg/m2 with body mass index (P =0.375).Both of the median of charlson comorbidity index (P =0.931) and American Society of Anesthesiologists score (P =0.254) were 2 There was no statistical significance between the two groups for type of urinary diversion and preoperative laboratory studies (P ＞ 0.05).Patients' perioperative outcomes,early (30-day) complications and postoperative readmission rate were compared.Results The ERAS group had less intraoperative crystalloid infusion [(950.0 ± 474.3) ml vs.(1 797.4 ± 448.1) ml,P ＜ 0.001],faster removed gastric tube (0 d vs.4 d,P ＜0.001),and shorter passing flatus time [(1.6 ± 0.8) d vs.(2.9 ± 1.4) d,P =0.006] than the CRAS group;however,no difference was found in terms of intraoperative colliod infusion [(1 110.0 ± 331.5)ml vs.(1 117.9 ± 397.9) ml,P =0.954].No patients from either group required conversion to open surgery.There was no significant difference between the two groups for operative time (P =0.311),estimated blood loss (P =0.073),drain days (P =0.681),postoperative hospital stay (P =0.509),overall blood transfusion (P =1.000),intensive care unit stay (P =1.000) and tumor characteristics (pathological stage,histology,nodes removed,positive nodes,lymph node-positive patients,positive surgical margins).The 30-day postoperative complications were documented in 5 (50％)and 23 (59％)patients in groups ERAS and CRAS (P =0.878),respectively.And the most common complication were minor complications (Clavien-Dindo grade 1 and 2) in both groups (100.0％ vs.86.9％,P =0.729).The 30-day readmission rate was 20.0％ (2 patients) in ERAS group and 10.3％ (4 patients) in CRAS group with no statistical significance(P =0.588).Conclusions Our ERAS protocol expedited bowel function recovery after RC and urinary diversion without increasing in 30-day complications compared with CRAS.The key of implement ERAS pathway is to explore and develop their own protocol conformed to their medical treatment enviroment.
ABSTRACT
Objective To evaluate the correlation between Narcotrend index (NI) and the depth of anesthesia during inhalation anesthesia with sevoflurane and compare NI with BIS values in patients.Methods Sixtytwo ASA physical status Ⅰ or Ⅱ patients,aged 25-60 yr,weighing 44-100kg,scheduled for elective surgeries under general anesthesia,were enrolled in the study.Sevoflurane inhalation was started at 5 min after endotracheal intubation.When the end-tidal concentration of sevoflurane (ETsevo) reached 0.6％,0.9％,1.3％,1.6％,2.1％,2.4％,2.9％,3.2％,3.8％ and 4.2％,NI and BIS values were recorded simultaneously.Results The correlation coefficients between ETsevo and NI and BIS values were-0.627 (r1) and-0.669 (r2) respectively when ETsevo ＜ 2.9％,and-0.608 (r3) and-0.230 (r4) respectively when 2.9％ ≤ ETsevo ≤4.2％ (P ＜ 0.01).Comparison of the absolute value of correlation coefficients:no significant difference was found between r1,r2 and r3 (P ＞ 0.05) ; r1,r2 and r3 were significantly greater than r4 (P ＜ 0.01).Conclusion When ETsevo 4.2％,NI values can accurately reflect the depth of anesthesia; when 2.9％ ≤ ETsevo ≤4.2％,the accuracy of NI values in monitoring the depth of anesthesia is superior to that of BIS values.
ABSTRACT
Objective To evaluate the advantages and disadvantages of Narcotrend(NT)in monitoring the depth of anesthesia when compared with the bispectral index.Methods Eighty ASA Ⅰ or Ⅱ patients of both sexes,aged 19-60 yr,undergoing elective surgery,were enrolled in this clinical study.Propofol was given by target-controlled infusion(TCI).After the initial target plasma concentration of 2.1 μg/ml was achieved,the concentration was increased by 0.3 μg/ml every 30 s until the patients lost consciousness.Then the effect-site concentralion of propofol was increased by 0.5μg/ml to maintain anesthesia and rocuronium 0.8 mg /kg was injected intravenously 30 s later.Tracheal intubation was performed 3 min after rocuronium injection.Mean arterial pressure (MAP),HR,NT value and BIS value were measured before TCI of propofol(baseline),al loss of consciousness,immediately before rocuronium administration,2 min after rocuronium administration,during intubation,and at 1 and 3 min after intubation.Results NT and BIS values were significantly decreased at loss of consciousness as compared with the baseline value(P ＜ 0.01).NT and BIS values were significantly lower at 2 min after rcuronium administration than before rocuronium administration(P ＜ 0.05).Compared with that before intubalion,HR and MAP were significantly increased during intuhation,and at 1 and 3 min after intubation,while no significant change was found in NT and BIS values(P ＞ 0.05).Conctusion NT can monitor the sedative effecl induced with TCI of propofol accuralely,the myoelectric activity exerts an obvious effect,and the accuracy of NT for monitoring the analgesic effect is lower.NT and BIS are comparable with respect to the advantages and disadvantages.
ABSTRACT
Objective: To observe the effect of Kangqianling Granules (Radix Salviae miltiorrhizae,Radix et Rhizoma Rhei, Radix Achyranthis Bidentatae, etc.) on renal function and renal fibrosis in chronic renal faiure(CRF). Methods: Effect of Kangqianling Granules on Serum Creatinine (SCR), Blood Urea Nitrogen (BUN), Laminin (LN), Fibronectin (FN), Precollagen Ⅲ (PC Ⅲ) and Collagen Ⅳ (C Ⅳ) were observed in CRF patients and rats with 5/6 nephrectomy. The expression of FN and C Ⅳ in remnent renal tissue of model rats were determined by immunhistochemistry. Results: Kangqianling Granules decreased significently serum volume for Scr, BUN, LN, PC Ⅲ, C Ⅳ and elevated FN considerably in CRF patients and rats. Kangqianling Granules inhibited the expressions of FN and C Ⅳ protein in remnant renal tissue of model rats. Conclusion:Kangqianling Granules could relieve renal fibrosis and delay process of CRF.
