ABSTRACT
Objective:To explore the effect of Xingnao Kaiqiao acupuncture treatment on brain network reorganization for the patients with stroke recovery, and therefore understand the neural mechanism underlying Xingnao Kaiqiao acupuncture treatment.Methods:Prospective case series study. Thirteen acute ischemia stroke patients were recruited from the Department of Neurology, Shanghai Minhang Hospital of Integrated Traditional Chinese and Western Medicine from Aug 2018 to Oct 2019. They were treated with Xingnao Kaiqiao acupuncture once a day for 10 consecutive days in addition to routine treatments, and received clinical assessments before treatment and 14 days after treatment onset. EEG signals were recorded during the first acupuncture treatment, from before inserting the needles (the baseline), during needle retention, to after removal of the needles. The brain network was constructed using phase locking index, and its clustering coefficient (CC), characteristic path length (PL) and small-worldness (S) were analyzed using one-way repeated ANOVA.Results:Compared with the baseline, the CC of delta-band network (sparsity=0.10: t=3.306, P=0.006; 0.12: t=2.909, P=0.013; 0.14: t=2.331, P=0.038) and the PL of delta-band (sparsity=0.12: t=3.236, P=0.007; 0.14: t=2.754, P=0.017, 0.18: t=2.878, P=0.014) and alpha-band (sparsity=0.10: t=2.432, P=0.032) networks were significantly decreased during the needle retention stage. Clinical assessments demonstrated a significant treatment efficacy of Xingnao Kaiqiao acupuncture, and its efficacy which was indicated by improved NIHSS score, was significantly correlated with the CC changes in the delta band network from baseline to needle retention. The correlation was strongest when the network sparsity was 0.12 ( r=0.78, P=0.002). Conclusion:Xingnao Kaiqiao acupuncture can regulate the brain network of stroke patients in real time, and this immediate regulation maybe associated with its treatment effect.
ABSTRACT
Objective:To investigate the effect of lymph node metastasis on the prognosis of patients with G2 phase stage pancreatic neuroendocrine neoplasm(pNEN).Methods:A retrospective case control study was conducted to analyze the case data of 368 patients with pancreatic neuroendocrine tumors in G2 phase stage from January 1, 2010 to December 31, 2016 in SEER database, including 174 males and 194 females. According to whether lymph nodes were metastatic, they are divided into lymph node non metastatic (N0) group ( n=272) and lymph node metastatic (N1) group ( n=96). The Kaplan-Meier method and Log-rank test were used to compare the overall survival rate (OS) of patients in the N0 and N1 groups. The COX proportional risk model was used to evaluate whether N stage was an independent risk factor affecting prognosis. Count data were expressed as cases and percentage(%), and Chi-square test was used for comparison between the groups. Results:Among all patients, the OS of patients in the N0 group was better than that of patients in the N1 group. The OS of N0 patients at 1, 3, and 5 years was 96.3%, 92.7%, and 85.6%, respectively, while the OS of N1 patients at 1, 3, and 5 years was 92.6%, 82.1%, and 82.1%, respectively ( P=0.014). Multivariate analysis showed that age ( HR=2.245, 95% CI: 1.126-4.475, P=0.022) and N stage ( HR=0.457, 95% CI: 0.237-0.883, P=0.020) were independent prognostic factors for G2 phase pNEN patients. Conclusion:Lymph node metastasis is one of the independent prognostic factors in patients with G2 phase stage pNEN.
ABSTRACT
Objective To evaluate the application value of perioperative interventional strategy guided by enhanced recovery after surgery (ERAS) in elderly recipients undergoing liver transplantation. Methods Clinical data of 405 liver transplant recipients were retrospectively analyzed. According to age, all recipients were divided into the elderly (≥60 years, n=122) and non-elderly groups (< 60 years, n=283). All patients received perioperative interventions under the guidance of ERAS. Intraoperative and postoperative indexes, incidence of postoperative complications and discharge were analyzed between two groups. Results There were no significant differences in the duration of anesthesia, operation time, anhepatic phase, hemorrhage volume, blood transfusion volume, lactic acid level before abdominal closure, ventilator-assisted time, the length of intensive care unit (ICU) stay, Caprini score, CHIPPS score, time of gastric tube, urinary tube and drainage tube removal, time to first drinking, time to first physical activity and time to first flatus between two groups (all P > 0.05). In the elderly group, the time to first feeding was later than that in the non-elderly group (P < 0.05). There were no significant differences in the incidence of fever, ascites, pulmonary infection, delayed gastric emptying, hemorrhage and inactive venous thrombosis between two groups (all P > 0.05). No significant differences were observed in the levels of aspartate aminotransferase, total bilirubin, direct bilirubin, serum creatinine before discharge and total length of hospital stay between two groups (all P > 0.05). The alanine aminotransferase level in elderly recipients was lower than that in non-elderly counterparts, and the difference was statistically significant (P < 0.05). No unplanned reoperation was performed within postoperative 30 d in two groups. There was no significant difference in the re-hospitalization rate within 30 d after discharge (P > 0.05). Conclusions ERAS-guided interventional strategy contributes to perioperative recovery of elderly recipients undergoing liver transplantation, and yields equivalent postoperative recovery between elderly and non-elderly recipients.
ABSTRACT
Objective To evaluate the changes and significance of lymphocyte subsets in the recipients with acute rejection after liver transplantation. Methods The recipients presenting with acute rejection after liver transplantation were assigned into the rejection group (n=17), and their counterparts with stable liver function were allocated into the control group (n=17) according to the ratio of 1∶1 by propensity score matching method. The incidence of acute rejection after liver transplantation was analyzed, and the concentration of tacrolimus in the recipients was compared between two groups. The absolute value and proportion of lymphocyte subsets in peripheral blood were compared between two groups. The diagnostic value of lymphocyte subsets for acute rejection after liver transplantation was assessed by the receiver operating characteristic (ROC) curve. The absolute value and proportion of lymphocyte subsets in the rejection group were compared before and after treatment. Results Among 17 recipients in the rejection group, 4 cases developed acute rejection within postoperative 28 d, and 13 cases had acute rejection within postoperative 29-180 d. No significant difference was noted in the tacrolimus concentration between two groups (P=0.295). Compared with the control group, the proportions of peripheral blood T cells, CD4+T cells, B cells and natural killer (NK) T cells were significantly increased in the rejection group (all P < 0.05). The elevated proportion of NKT cells in the early stage after liver transplantation was an independent risk factor for acute rejection following liver transplantation[odds ratio (OR) 1.774, 95% confidence interval (CI) 1.059-2.971, P=0.029]. ROC curve analysis showed that the area under curve (AUC) of CD4+T cells, B cells and NKT cells was 0.76, 0.73 and 0.77, respectively. The AUC of combined use of CD4+T cells, B cells and NKT cells was 0.89, with a cut-off value of 0.69, sensitivity of 0.706 and specificity of 0.941. After corresponding treatment, all recipients were gradually recovered, and liver functions were eventually restored to normal in the rejection group. After treatment, the proportion of T cells, CD4+T cells, CD8+T cells and NK cells was significantly decreased (all P < 0.05). Conclusions The elevated proportion of NKT cells indicates an increased risk of acute rejection after liver transplantation. Combined use of CD4+T cells, B cells and NKT cells may deliver early detection and diagnosis of acute rejection after liver transplantation.
ABSTRACT
Objective:To explore the risk factors of Pneumocystis carinii pneumonia (PCP) after orthotopic liver transplantation (OLT), and optimize the treatment strategy. Methods:From May 2015 to March 2019, patients undergoing OLT and suffering from postoperative PCP were selected into PCP group ( n=8). Using the propensity score matching method, controls without postoperative PCP were selected from concurrent OLT patients at a ratio of 1: 4 ( n=32). Clinical data were collected and counted for analyzing the risk factors of PCP post-OLT. Results:During this period, 385 cases of OLT were performed. The incidence of PCP was 2.1% (8/385). PCP group were all males with an average age of (52.63±12.99)(27-69) years. PCP has an average onset time of (19.88±13.22)(9-50) weeks post-OLT. There were benign liver disease ( n=2) and malignant liver tumor ( n=6). All operative approaches were modified camel OLT. Univariate analysis revealed significant differences in rejection, peripheral blood lymphocyte count and percentage of peripheral blood lymphocyte after OLT ( P<0.05) and no significant differences existed in other factors ( P>0.05). Logistic regression analysis indicated that a lower count of peripheral blood lymphocyte post-OLT was an independent risk factor for postoperative PCP. Conclusions:A lower count of peripheral blood lymphocyte post-OLT elevates the risk of PCP. For high-risk patients, prophylaxis with TMP-SMX (trimethoprim-sulfamethoxazole) may effectively lower the incidence of PCP post-OLT.
ABSTRACT
Background@#We hypothesized that specific amino acids or acylcarnitines would have benefits for the differential diagnosis of diabetes. Thus, a targeted metabolomics for amino acids and acylcarnitines in patients with diabetes and its complications was carried out. @*Methods@#A cohort of 54 normal individuals and 156 patients with type 2 diabetes mellitus and/or diabetic complications enrolled from the First Affiliated Hospital of Jinzhou Medical University was studied. The subjects were divided into five main groups: normal individuals, impaired fasting glucose, overt diabetes, diabetic microvascular complications, and diabetic peripheral vascular disease. The technique of tandem mass spectrometry was applied to obtain the plasma metabolite profiles. Metabolomics multivariate statistics were applied for the metabolic data analysis and the differential metabolites determination. @*Results@#A total of 10 cross-comparisons within diabetes and its complications were designed to explore the differential metabolites. The results demonstrated that eight comparisons existed and yielded significant metabolic differences. A total number of 24 differential metabolites were determined from six selected comparisons, including up-regulated amino acids, down-regulated medium-chain and long-chain acylcarnitines. Altered differential metabolites provided six panels of biomarkers, which were helpful in distinguishing diabetic patients. @*Conclusion@#Our results demonstrated that the biomarker panels consisted of specific amino acids and acylcarnitines which could reflect the metabolic variations among the different stages of diabetes and might be useful for the differential diagnosis of prediabetes, overt diabetes and diabetic complications.

@#Objective To explore the clinical efficacy of liver transplantation for severe liver disease. Methods The clinical data of 51 patients who underwent liver transplantation for severe liver disease were retrospectively analyzed. The general intraoperative conditions were observed, including operation duration, warm ischemia time, cold ischemia time, anhepatic phase, bleeding volume, blood transfusion volume, plasma transfusion volume and so on. The changes in indexes such as total bilirubin (TB), prothrombin time activity (PTA), and prothrombin time international normalized ratio (PT-INR) were observed before operation and at 3 d, 1 week and 2 weeks after operation. The postoperative survival and occurrence of complications were analyzed. The indexes that might affect the prognosis of patients with severe liver disease were analyzed by Cox regression analysis. Results For the 51 patients, operation duration, warm ischemia time and cold ischemia time was 8 (7, 9) h, 3 (2, 3) min and 6 (5, 8) h respectively, intraoperative anhepatic phase was 80 (70, 100) min, intraoperative bleeding volume was 1 000 (550, 1 500) mL, and intraoperative blood transfusion volume was 1 200 (200, 1 600) mL. Postoperative TB, PTA, PT-INR and other indexes improved significantly compared to those preoperatively. Among the 51 patients, 10 cases died, with the death causes of multiple organ failure and severe infection(7 cases), renal insufficiency (2 cases), and cardiovascular complications (1 case). Survival rates at 1 month and 1 year post-transplantation for patients with severe liver disease were 82% and 80%, respectively. Cox regression analysis suggested that abnormal preoperative PTA and PT-INR were the risk factors for post-transplantation death in patients with severe liver disease. Conclusions Liver transplantation significantly improves the survival rate for patients with severe liver disease, perioperative infection prevention and treatment as well as multiple organ function management play key roles in improving post-transplantation survival rate in patients with severe liver disease.
