Objective To study the effect of perioperative nutritional support on protein metabolism and immunity in patients underwent liver transplantation. Methods A total of 80 patients who underwent liver transplantation in our hospital from March 2015 to March 2016 were collected retrospectively, and then the 80 patients were divided into control group (n=40) and observation group (n=40) according to the type of perioperative nutritional support. Patients of control group didn’t receive preoperatively nutritional support, and received total parenteral nutrition support before postoperative exhaust, then received enteral nutrition support after anal exhaust. Patients of observation group receive preoperatively nutritional support before surgery, and received parenteral nutrition and enteral nutrition support before postoperative exhaust. The several parameters about nutritional status and immune function were observed on 7 days and 14 days after liver transplantation, and comparison of the 2 group in these parameters was performed. Results On the protein metabolism, the levels of serum transferrin, prealbumin, and nitrogen balance on 14 days after liver transplantation were higher than those of other time points (before liver transplantation and 7 days after liver transplantation),P<0.05, both in control group and observation group. There was no significant difference in the levels of serum transferrin, prealbumin, and value of nitrogen balance between the 2 groups before liver transplantation (P>0.05). But on 7 days and 14 days after liver transplantation, the levels of serum transferrin, prealbumin, and value of nitrogen balance of the observation group were higher than those of control group (P<0.05). On the immunity, the total number of lymphocytes, value of IgG and CD4/CD8 on 14 days after liver transplantation, were superior to other time points (before liver transplantation and 7 days after liver transplantation),P<0.05, both in control group and observation group. There was no significant difference in the total number of lymphocytes, value of IgG and CD4/CD8 between the 2 groups before liver transplantation (P>0.05). But on 7 days and 14 days after liver transplantation, the levels of the total number of lymphocytes, value of IgG and CD4/CD8 in the observation group were superior to those of control group (P<0.05). Conclusion Perioperative nutritional support can improve the nutritional status and immune function in patients underwent liver transplantation.
Objective To explore the effect of lean management on patients’ safety, medical quality, and satisfaction in day surgery ward. Methods The patients underwent day surgery between May 4th, 2017 and April 30th, 2018 were selected as the subjects (the lean management of day surgery ward implemented on November 1st, 2017). The patients underwent day surgery between May 4th and October 31st, 2017 were taken as the control group (n=2 864), and the ones between November 1st, 2017 to April 30th, 2018 were taken as the observation group (n=2 705). The following data between the two groups were compared: the cancellation rate of day surgery, the 24-hour delayed discharge rate, the rate of 12-hour median or severe pain after surgery, the rate of 12-hour postoperative nausea and vomiting, the awareness rate of health education, the patients’ satisfaction, and the incidence of adverse events.Results Compared with those in the control group, the cancellation rate of surgery (4.81% vs. 6.25%), the 24-hour delayed discharge rate (2.76% vs. 4.28%), the 12-hour median or severe pain after surgery (5.55% vs. 8.31%), the rate of 12-hour postoperative nausea and vomiting (5.86% vs. 7.71%) decreased in the observation group, and the differences were statistically significant (P<0.05). The awareness rate of health education increased from 92.18% to 98.02% after the implementation of lean management, the patients’ satisfaction increased from 92.48±2.58 to 96.53±1.64 after the implementation of lean management, and the differences were statistically significant (P<0.05). The incidences of adverse events in the two groups were not statistically different (0.16% vs. 0.41%, P>0.05). Conclusion The implementation of lean management model can insure the medical safety and quality of day surgery, and improve overall work efficiency and the patients’ medical service experience in day surgery ward.
ObjectiveTo explore the associations between estrogen receptor α (ESR1) gene intron 1 PvuⅡ (−397 T/C, rs2334693), XbaⅠ (−351 A/G, rs9340799) polymorphisms and premature ovarian failure (POF).MethodsLiterature published before February 2021 were retrieved in PubMed, Web of Science, China National Knowledge Infrastructure, Wanfang, and CQVIP databases, according to the inclusion and exclusion criteria developed before. Odds ratio (OR) and 95% confidence interval (CI) were used for data analysis, the Q test and I2 statistic were used for heterogeneity analysis. Random-effect model or fixed-effect model was used according to I2 value. All analyses were performed by RevMan 5.3 software.ResultsSix case-control studies were included in this meta-analysis. For the associations between ESR1 gene intron 1 PvuⅡ polymorphisms and POF, there was no statistical difference in TT vs. CC model [OR=0.72, 95%CI (0.31, 1.70), P=0.46], TC vs. CC model [OR=1.09, 95%CI (0.83, 1.43), P=0.54], recessive model [OR=1.08, 95%CI (0.68, 1.70), P=0.74], or dominant model [OR=0.77, 95%CI (0.42, 1.42), P=0.41]. For the associations between ESR1 gene intron 1 XbaⅠ polymorphisms and POF, there was no statistical difference in AA vs. GG model [OR=0.88, 95%CI (0.44, 1.75), P=0.72], AG vs. GG model [OR=1.23, 95%CI (0.84, 1.79), P=0.29], recessive model [OR=1.14, 95%CI (0.81, 1.61), P=0.44], or dominant model [OR=0.75, 95%CI (0.41, 1.35), P=0.34], either. No statistical difference was found in the ethno-based subgroup analyses (P>0.05). Most models had obvious heterogeneities.ConclusionsCurrent evidence can’t confirm the associations between ESR1 gene PvuⅡ, XbaⅠ polymorphisms and POF. High-quality, multi-central and large-sample studies are still necessary to support this conclusion.
Objective To investigate the differences in characteristics and susceptibility factors between infectious stones and calcium oxalate stones, and provide reference value for screening infectious stones in clinical work. Methods According to the results of analysis of stone components in the extracorporeal shock wave lithotripsy center of West China Hospital of Sichuan University between June 2014 and April 2017, 392 patients with infectious stones (including 56 patients with magnesium ammonium phosphate stones in group A and 336 patients with calcium carbonate apatite in group B) and 392 patients with calcium oxalate stone (group C) were selected to discuss the difference of clinical features by retrospectively analyzing the clinical data. Results The proportion of females, the long diameter of stones and the proportion of staghorn stones in group A [75.0%, (3.9±2.5) cm, 41.1%] were higher than those in group B [39.3%, (2.4±1.3) cm, 6.0%], and the proportion of females and the long diameter of stones in group A and B were larger than those in group C [30.1%, (1.9±0.7) cm]; the differences above were statistically significant (P<0.05). There was no significant difference among the three groups in surgically history or complicated factors of urinary tract such as ureteral stricture (P>0.05). The prevalences of diabetes, renal tubular acidosis and hyperlipidemia in patients with infectious stones were higher than those in group C. The prevalences of renal tubular acidosis and hyperlipidemia in group A (16.1%, 39.3%) were higher than those in group B (0.6%, 21.1%), the positive rate of urine culture in group A (58.9%) was higher than that in group B (20.5%), which were both higher than that in group C (8.9%); these differences were statistically significant (P<0.017). The bacteria cultured from urine were mainlyProteus mirabilis and Escherichia coli in group A, and Escherichia coli in group B and group C. Conclusion Patients with large volume of stones, complicated with diabetes, renal tubular acidosis, hyperlipidemia and positive urine culture are more likely to have infectious stones.
