ObjectiveTo study effect of Herba Erigerontis on metabolites in cerebral ischemia rats with high-resolution magic angle spinning 1H nuclear magnetic resonance spectroscopy(HR MAS 1H NMR). Methods18 male Wistar rats, weighing 150～200 g, were randomly divided into 3 groups such as normal (n=6), ischemia (n=6), Herba Erigerontis treatment (n=6). Rat ischemia model was established with middle cerebral artery occlusion (MCAO), reperfusing or dosed with Herba Erigerontis after 3 h ischemia. The metabolites, including N-acetylaspartate (NAA), creatine (Cre), choline (Cho), glutamate (Glu), and aspartate (Asp) etc., of cerebra and cerebella was observed using HR MAS 1H NMR. ResultsExcluding Cho, Glu, Asp, the concentrations of most metabolites of rat brain during ischemia were significantly lower than that of normal rats, and could be increased after drug treatment. ConclusionHerba Erigerontis shows positive effect on metabolites in cerebral ischemia rats.

Objective To assess the efficacy of Sevoflurane-Remifentanil anesthesia in pediatric fiberoptic bron-choscopy (FOB) compared with a Propofol-Remifentanil regimen. Methods 60 children scheduled for fiberoptic bronchoscopy were randomly divided into two groups ( = 30 in each group): In group S, patients received Sevoflu-rane inhalation and intravenous infusion with Remifentanil. In group P, patients received total intravenous anesthesia with Propofol and Remifentanil. Standard laryngeal mask airways (LMA) were inserted into all children in two groups after anesthesia and fiberoptic bronchoscopy was carried out via LPA. MAP, HR, SpO2, PETCO2 and BIS were record-ed before anesthesia (T0, baseline), before FOB (T1), 2 min after FOB (T2). Then assess the effect of general anesthe-sia. Procedure time, recovery time and incidence of adverse events were also recorded. Results HR, MAP and SpO2 at T1 and SpO2 at T2 in group P were significantly lower than those in group S. PETCO2 at T1 and MAP, HR, PETCO2 at T2 in group P were significantly higher than those in group S. Better quality of anesthesia, less respiratory depression, and less interruption needed during procedure were found in group S. Conclusion Compared with Propofol-based to-tal intravenous anesthesia, Sevoflurane inhalation via laryngeal mask combined with intravenous Remifentanil pro-vides a superior profile in pediatric fiberoptic bronchoscopy.

ObjectiveTo investigate the effect and medical cost of different revascularization strategies for acute myocardial infarction (AMI) patients with multi-vessel disease (MVD).Methods A prospective randomized controlled trial (RCT) was conducted. From January 2009 to June 2012, patients with AMI and MVD undergoing primary percutaneous coronary intervention (PCI) were enrolled. They were randomly assigned to group A [staged PCI for non-infarction related artery (non-IRA) within 7-10 days after AMI] and group B (subsequent PCI for non-IRA recommended only for those with evidence of ischemia). All of patients were given optimized medical therapy according to clinical guideline, and they were followed up for 24 months at regular intervals. Major adverse cardiovascular events(MACE) including recurrence of myocardial infarction and death due to cardiac ailments were recorded. Meanwhile, re-hospitalization from cardiac causes, recurrence of angina, heart failure, and re-PCI, number of stents, total hospital stay days, and total medical expenditure were recorded.Results A total of 428 patients accomplished the 24-month follow up. All the patients underwgennt PCI for non-IRA in group A (215 patients), while 62 patients in group B (213 patients) undergone PCI for myocardial ischemia, and 51 patients received non-IRA treatment. There was no significant difference in MACE incidence between group A and group B [8.4% (18/215) vs. 10.8% (23/213),χ2= 0.727,P = 0.394]. The difference of death rate due to cardiac causes (5.1% vs. 6.6%), recurrence of myocardial infarction (4.2% vs. 6.6%), and heart failure (4.2% vs. 7.0%) were not significantly different between groups A and B (allP> 0.05). The rate of recurrence of angina (14.4 % vs. 32.9%), re-hospitalization from cardiac causes (14.4% vs. 33.8%), and re-treatment of implanting stents (12.6% vs. 29.1%) were significantly lower in group A than group B (allP< 0.01), and the rate of revascularization was significantly higher in group A than group B (10.7% vs. 5.2%,P< 0.05). The total number of stents (610 vs. 366), mean number of stents per patient (2.83±0.91 vs. 1.72±0.91,t = 12.725,P = 0.000), and total cost per patient (kRMB: 63.7±12.6 vs. 51.5±12.3,t = 10.107,P = 0.000) in group A were significantly higher than those in group B. Total hospital stay days in group A was significantly less than group B (days: 8.21±2.45 vs. 9.89±3.23, t = 6.071,P = 0.000). Because non-IRA-vascular reconstruction rate was low in group B, the rate of usingβ-blocker and anti-anginal agents during the 24-month follow up in group B was significantly higher than group A [59.2% (126/213) vs. 47.0% (101/215),χ2= 6.371,P = 0.012; 56.3% (112/213) vs. 17.6% (36/215),χ2 = 64.704,P = 0.000]. Conclusions In patients with AMI and MVD undergone emergency PCI, staged PCI within 7-10 days for non-IRA cannot decrease the incidence of myocardial infarction and death due to cardiac causes, recurrence of angina and rehospitalization for cardiac causes was diminished, and it may increase the number of stents and medical cost significantly.

Objective:To investigate the predictive values of baseline hematoma mean CT value and shape regularity (SR) for hematoma enlargement (HE) in patients with spontaneous intracerebral hemorrhage (ICH).Methods:Patients with ICH admitted to Yulin First Hospital from June 2018 to December 2021 were retrospectively included. The first head CT scan was performed within 24 h of onset, and the second head CT scan was performed within 72 h of the first scan. HE was defined as an increase in hematoma volume of at least 6 ml or 33% from the first CT. 3D Slicer software was used to reconstruct 3D images and SR was calculated. Multivariate logistic regression analysis was used to determine the independent factor for HE. Receiver operator characteristic (ROC) curve was used to evaluate the predictive value of baseline hematoma mean CT value for HE. Results:A total of 249 patients with ICH were enrolled, including 134 males (53.8%), and aged 62.2±12.1 years. The median baseline Glasgow Coma Scale score was 12, and the median time from onset to first CT scan was 3.1 h. The median baseline hematoma volume was 10.9 ml, and 58 patients (23.3%) showed HE. The baseline hematoma mean CT value in the HE group (58.5±3.2 HU vs. 60.3±3.3 HU; P<0.01) and baseline SR (0.615±0.146 vs. 0.688±0.100; P<0.001) were significantly lower in the non-HE group. Multivariate logistic regression analysis showed that the time from onset to first CT scan (odds ratio [ OR] 0.867, 95% confidence interval [ CI] 0.786-0.957; P=0.004), the baseline hematoma volume ( OR 1.050, 95% CI 1.028-1.073; P<0.001), and the baseline hematoma mean CT value ( OR 0.809, 95% CI 0.725-0.902; P<0.001) were the independent predictors of HE, while the baseline SR had no significant independent correlation with HE. ROC curve analysis showed that the area under the curve of baseline hematoma mean CT value for predicting HE was 0.652 (95% CI 0.573-0.731; P<0.001), with an optimal cutoff value of 57.97 HU. The sensitivity and specificity for predicting HE were 50% and 75.9%, respectively. Conclusion:The baseline hematoma mean CT value is an independent factor for HE in patients with ICH and has certain predictive value for HE.

Objective:To evaluate the efficacy and toxicity of single-agent bendamustine in patients with indolent B-cell non-Hodgkin's lymphoma (NHL) refractory to rituximab. Methods:Between April 2010 and April 2013, 100 patients with rituximab-refrac-tory indolent B-cell NHL from 8 institutions were enrolled. Bendamustine was administered at 120 mg/m2 on days 1 and 2 every 21 days for 6-8 cycles. The primary endpoint was the overall response rate (ORR). The secondary endpoints included disease control rate (DCR), progression-free survival (PFS), overall survival (OS), and safety. Results:One hundred patients with a median age of 56 (rang-ing from 28 to 74) years were recruited in this clinical study. The total number of chemotherapy was 447 cycles, and the median number was 4 cycles. Ninety-three patients could be evaluated for efficacy. Fifteen patients (16.1%) had complete remission (CR), 52 (55.9%) had partial remission (PR), 22 (23.7%) had stable disease (SD), and 4 (4.3%) had progression disease (PD). The ORR and DCR were 72%and 95.7%, respectively. After a median follow-up of 26.6 months (ranging from 2 to 48.4 months), 59 patients (63.4%) had PD.The median PFS was 8.53 (95%CI:6.518-10.542) months, and PFS rate for 1 year was (40.6±5.3)%. Forty-eight patients (48%) had 3/4 grade adverse events, including leucopenia (26%), neutropenia (24%), and anemia (11%). Conclusion:Single-agent bendamustine produced a high rate of objective responses in patients with rituximab-refractory indolent B-cell NHL and could be one of the new op-tions for second-line treatment of these patients. The most common adverse event is hematologic toxicity.

Objective:To investigate levels of autophagy in T cells and B cell of patients with systemic lupus erythematosus ( SLE) and its clinical significance.Methods: 68 SLE patients without treatment within 4 weeks were enrolled in this study.We accessed the levels of autophagy in T cells and B cells of 23 healthy controls and 68 patients before and after treatment by flow cytometry,and analyzed their correlations with serum levels of C3 and anti-dsDNA antibodies,SLEDAI score,et al.Results: Before treatment,a significantly increased levels of LC3-Ⅱ was observed in SLE patients than healthy controls, the active group ( SLEDAI score≥10) was significantly higher than the stable group(SLEDAI score<10),and the newly diagnosed group was significantly higher than the recurrent group(all P<0.05).While the levels of LC3-Ⅱ was decreased in B lymphocytes in SLE patients,the active group was significantly lower than stable group,and the active group was significantly lower than the newly diagnosed group(all P<0.05). Correlation analysis found that,a positively correlation was observed for the levels of LC3-Ⅱwith SLEDAI score in T lymphocyte( rs=0.289,P<0.05),and the levels of C3 were positively correlated the levels of LC3-Ⅱ in B lymphocyte(rs=0.371,P<0.01).After treatment for five days, levels of autophagy in T lymphocytes of SLE patients with good prognosis ( SLEDAI score decreased ≥4 ) significantly decreased(P<0.05).Also,three days after treatment,levels of autophagy in B lymphocytes of SLE patients with good prognosis were increased significantly ( P<0.05 ) .However, SLE patients with poor prognosis had no such difference ( P>0.05 ) . Conclusion:Levels of autophagy in T and B lymphocytes of SLE patients are abnormal compared to healthy controls,and these changes are associated with disease activity.Also,these changes are expected to be the indicators of disease activity and potential therapeutic targets in SLE.

Objective To summarize the experiences of aneurysmorrhaphy for arteriovenous fistula aneurysms with acute thrombosis in hemodialysis patients.Methods There were 7 cases of arteriovenous fistula with acute thrombosis from Nov 2015 to Feb 2017 at our department of vascular surgery,Longhua Hospital.Results In all cases thrombosis was secondary to proximal stenosis or occlusion.The stenosis and occlusion were corrected with embolectomy and aneurysmorrhaphy.The proximal part of the cephalic vein was translocated to the basilic vein in 1 case,axillary vein in 2 cases;autologous vein graft in 1 case;resection of the occlusion,end-to-end anastomosis in 1 case;autogenous patch in 1 case.No perioperative complications occurred.The operation site was cannulated within one month after operation in all cases.Patients were followed up for 7 months to 23 months,all cases were patent.Conclusions Aneurysmorrhaphy is effective,reliable and safe for arteriovenous fistula aneurysms with acute thrombosis in hemodialysis patients.

BACKGROUND/OBJECTIVES: This study examined the relationship between famine exposure in early life and the risk of type 2 diabetes in adulthood during the 1959–1961 Chinese Famine. SUBJECTS/METHODS: A total of 3,418 individuals aged 35–74 years free of diabetes from two studies in 2006 and 2009 were followed up prospectively in 2009 and 2012, respectively. Famine exposure was classified as unexposed (individuals born in 1962–1978), fetal exposed (individuals born in 1959–1961), child exposed (individuals born in 1949–1958), and adolescent/adult exposed (born in 1931–1948). A logistic regression model was used to assess the relationship between famine exposure and diabetes after adjustment for potential covariates. RESULTS: During a three-year follow-up, the age-adjusted incidence rates of type 2 diabetes were 5.7%, 14.5%, 12.7%, and 17.8% in unexposed, fetal-exposed, child-exposed, and adolescent/adult-exposed groups, respectively (P < 0.01). Relative to the unexposed group, the relative risks (95% confidence interval) for diabetes were 2.15 (1.29–3.60), 1.53 (0.93– 2.51), and 1.65 (0.75–3.63) in the fetal-exposed, child-exposed, and adolescent/adult-exposed groups, after controlling for potential covariates. The interactions between famine exposure and obesity, education level, and family history of diabetes were not observed, except for the urbanization type. Individuals living in rural areas with fetal and childhood famine exposure were at a higher risk of type 2 diabetes, with relative risks of 8.79 (1.82–42.54) and 2.33 (1.17–4.65), respectively. CONCLUSIONS These findings indicate that famine exposure in early life is an independent predictor of type 2 diabetes, particularly in women. Early identification and intervention may help prevent diabetes in later life.

Objective To explore the applicability of the three commonly used CT examination decision rules in Chinese head injured children. Methods This prospective observational study included 1538 children and adolescents (aged < 18 years), who were treated at the Emergency Department of First Hospital of Shanxi Medical University after head injuries. The three clinical decision rules include the Children's Head Injury Algorithm for the Prediction of Important Clinical Events (CHALICE; UK); the prediction rule for the identification of children at very low risk of clinically important traumatic brain injury, that was developed by the Pediatric Emergency Care Applied Research Network (PECARN; USA), and the Canadian Assessment of Tomography for Childhood Head Injury (CATCH) rule. Diagnostic accuracy had been evaluated by using the rule-specific predictor variables to predict each rule-specific outcome measure in populations who met inclusion and exclusion criteria for each rule. Sensitivity, specificity, negative predictive value (NPV), positive predictive value (PPV), and ROC curve were referred to the diagnostic accuracy. Indicators were characterized by 95％ CI. Results Of the 1538 patients, CTs were obtained for 339 patients (22.04％). Forty-nine patients (3.19％) had positive CT results, 8 patients (0.52％) underwent neurosurgery, 2 patients (0.13％) died, and 1 patient (0.07％) may be missed. In this study, CHALICE was applied for 1394 children (90.70％; 95％ CI: 89.24％-92.15％), PECARN for 801 children (52.11％; 95％ CI: 49.62％-54.61％), and CATCH for 325 patients (21.15％; 95％CI: 19.10％-23.19％). The validation sensitivities of CHALICE, PECARN, and CATCH rules were 92.6％(74.2％-98.7％), 100％ (56.1％-100％), and 85.7％ (42.0％-99.2％), respectively; the specificities were 78.1％(75.7％-80.2％), 48.0％ (44.5％-51.5％) and 70.8％ (65.4％-75.6％); positive predictive value were 7.7％ (5.1％-11.3％), 0.9％ (0.4％-1.9％) and 6.1％ (2.5％-13.2％); and negative predictive value were 99.8％ (99.2％-100％), 99.1％ (98.1％-99.6％), and 99.6％ (97.2％-100％), respectively. Conclusions The clinical decision rules of CHALICE, PECARN and CATCH have high sensitivities. The specificity of PECARN rule is lower than those of CHALICE and CATCH rules. The above three clinical decision rules can be used for the decision of CT examination in Chinese children with head injury in practice.
