Abstract
Objective: To explore the association of different obesity measurement indexes on serum C-reactive protein (CRP) in Chinese adult women. Methods: The data were obtained from baseline and follow-up surveys of the urban Breast Cancer Screening Program in Shuangliu District, Chengdu. A total of 441 adult women were included in the study. A questionnaire survey, physical examination, and laboratory testing were conducted on the subjects. Multivariate logistic regression model, two-level mixed effects logistic regression model, and restricted cubic spline method were used to investigate the linear and nonlinear correlation between different obesity measurement indexes and serum CRP in adult women. Results: For every 1 unit increase in BMI, waist circumference (WC), and adiposity, the risk of elevated serum CRP or exacerbation of chronic low-grade inflammation in adult women increased by 16.5%, 5.0%, and 11.1% (P<0.05), respectively. Both BMI and adiposity were nonlinear correlated with serum CRP. Using BMI=24.0 kg/m2 as the reference point, serum CRP level increased with the increase of BMI when BMI >24.0 kg/m2. Using adiposity=30% as the reference point, serum CRP level increased with the increase of adiposity when adiposity >30%. Conclusions: Overall, obesity reflected by BMI had the strongest association with serum CRP in adult women, followed by body fat content reflected by adiposity, and central obesity reflected by WC had the weakest association with CRP. Adult women with BMI >24.0 kg/m2 or adiposity >30% are at high risk for obesity-related inflammatory manifestations.

Abstract
Objective We aim to investigate the prognostic effects of metabolic syndrome (MS) on patients with non-ST elevated myocardial infarction (NSTEMI) after percutaneous coronary intervention (PCI). Methods Patients with NSTEMI undergoing PCI were consecutively collected. According to the presence or absence of MS, they were divided into two groups and followed up for 1 year. The endpoint was major adverse cardiovascular events (MACE), including all-cause death, unstable angina hospitalization, heart failure (HF) hospitalization, non-fatal recurrent myocardial infarction (MI), and target lesion revascularization. Also, six subgroups were made according to gender, age, left ventricular ejection fraction (LVEF), Global Registry of Acute Coronary Events (GRACE) score, hypersensitive troponin (hsTNT), and several diseased vessels. Cox proportional hazard model was adopted to analyze the effect of MS on MACE in all the patients and different subgroups. Results A total of 1,295 patients were included in the current analysis and 660 (50.97%) of them had MS. About 88 patients were lost to follow-up, and the overall average follow-up was 315 days. MS was an independent risk factor for MACE (HR 1.714, CI 1.265–2.322, p = 0.001), all-cause death, heart failure (HF) hospitalization, and non-fatal recurrent MI. In the MS component, BMI ≥28 kg/m2 was positively associated with MACE. Subgroup analysis indicated the prognostic value of MS was more striking for patients with the following: age of >60, LVEF of ≤40%, GRACE of >140, multivessel disease, or hsTNT of >0.1 ng/ml. Conclusions The MS was a robust adverse prognostic factor in patients diagnosed with NSTEMI, especially among those of older age and at higher ischemic risk. A BMI of ≥28 kg/m2 independently predicted the occurrence of MACE. Prognosis may be improved by controlling abdominal obesity.

Abstract
BACKGROUND Stent thrombosis (ST)-related ST-segment elevation myocardial infarction (STEMI) has very high mortality and poor prognosis. With the extensive construction of the chest pain center in China, the question arises as to whether these special patients will benefit. METHODS From January 2015 to February 2018, 316 patients with STEMI admitted to the coronary care unit (CCU) of Tianjin Chest Hospital after coronary stent implantation were enrolled in this retrospective study. All patients underwent coronary angiography. According to whether STEMI was due to ST, these patients were divided into either a ST group (n=247) or a non-ST group (n=69). The in-hospital mortality and major adverse cardiac events (MACEs), including all-cause mortality, re-ST, target vessel revascularization (TVR), and acute myocardial infarction (AMI) within the 1-year follow-up were compared between the two groups. RESULTS 78% of cases of STEMI following coronary stent implantation were caused by ST. The in-hospital mortality of the ST group was 0.8% and that of the non-ST group was 1.4% (P>0.05). Forty-two cases had MACEs in the 1-year follow-up, with a higher incidence in the ST group compared to the non-ST group (15.4% vs. 5.8%, P=0.038). The Kaplan-Meier survival analysis showed a lower 1-year event free survival (EFS) in the ST group compared to the non-ST group (84.6% vs. 94.2%, P=0.035). Age over 80-years-old, hypertension, diabetes, hypercholesterolemia, and family history of coronary artery disease (CAD) were all independent risk factors for MACE. CONCLUSION ST is the leading cause of STEMI in patients following coronary stent implantation. There was no significant difference in mortality between the ST group and the non-ST group during hospitalization, with a worse prognosis in the ST group during the 1-year follow-up.

Abstract
OBJECTIVE Public knowledge of early onset symptoms and risk factors (RF) of acute myocardial infarction (AMI) is very important for prevention, recurrence and guide medical seeking behaviours. This study aimed to identify clusters of knowledge on symptoms and RFs of AMI, compare characteristics and the awareness of the need for prompt treatment. DESIGN Multistage stratified sampling was used in this cross-sectional study. Latent GOLD Statistical Package was used to identify and classify the respondent subtypes of the knowledge on AMI symptoms or modifiable RFs. Multivariable logistic regression was performed to identify factors that predicted high knowledge membership. PARTICIPANTS A structured questionnaire was used to interview 4200 community residents aged over 35 in China. 4122 valid questionnaires were recovered. RESULTS For AMI symptoms and RFs, the knowledge levels were classified into two or three distinct clusters, respectively. 62.7% (Symptom High Knowledge Cluster) and 39.5% (RF High Knowledge Cluster) of the respondents were able to identify most of the symptoms and modifiable RFs. Respondents who were highly educated, had higher monthly household income, were insured, had regular physical examinations, had a disease history of AMI RFs, had AMI history in immediate family member or acquaintance or had received public education on AMI were observed to have higher probability of knowledge on symptoms and RFs. There was significant difference in awareness of the prompt treatment in case of AMI occurs among different clusters. 'Calling an ambulance' was the most popular option in response of seeing others presenting symptoms of AMI. CONCLUSIONS A moderate or relatively low knowledge on AMI symptoms and modifiable RFs was observed in our study. Identification of Knowledge Clusters could be a way to detect specific targeted groups with low knowledge of AMI, which may facilitate health education, further reduce the prehospital delay in China and improve patient outcomes.

Abstract
BACKGROUND The recurrence rate of ischemic symptoms after coronary artery bypass grafting (CABG) is increasing in recent years. How to prevent and treat saphenous vein graft disease (SVGD [symptomatic ⩾50% stenosis in at least one Saphenous vein graft]) has been a clinical challenge to date. Different pathogenesis may exist in SVGD of different periods. There are currently few available scores for estimating the risk of SVGD after one year post CABG. OBJECTIVE We sought to develop and validate a simple predictive clinical risk score for SVGD with recurring ischemia after one year post CABG. METHODS AND RESULTS This was a cross-sectional study and the results were validated using bootstrap resampling on a separate cohort. A nomogram and risk scoring system were developed based on retrospective data from a training cohort of 606 consecutive patients with recurring ischemia >1 year after CABG. Logistic regression model was used to find the predictive factors and to build a nomogram. To assess the generalization, models were validated using bootstrap resampling and an external cross-sectional study of 187 consecutive patients in four other hospitals. In multivariable analysis of the primary cohort, native lesion vessel number, SVG age, recurring ischemia type, very low-density lipoprotein level, and left ventricular end-diastolic diameter were independent predictors. A summary risk score was derived from nomogram, with a cut-off value of 15. In internal and external validation, the C-index was 0.86 and 0.82, indicating good discrimination. The calibration curve for probability of SVGD showed optimal agreement between actual observations and risk score prediction. CONCLUSION A simple-to-use risk scoring system based on five easily variables was developed and validated to predict the risk of SVGD among patients who recurring ischemia after one year post CABG. This score may be useful for providing patients with individualized estimates of SVGD risk.

Abstract
Objective To investigate the relevance between interventional time and clinical outcomes in non-ST-elevation myocardial infarction (NSTEMI) patients of different risk stratifications, which were divided into different groups according to GRACE scores and the time from admission to percutaneous coronary intervention (PCI). Method Patients were grouped according to the GRACE score and the time from admission to intervention therapy. The Cox multivariate risk regression model was used to analyze the correlation between the GRACE score and the time from admission to intervention therapy with major adverse cardiovascular events (MACEs). Cox interactive item regression was also used to investigate the correlation between the time of intervention therapy and GRACE risk stratification with clinical outcomes and to evaluate the efficacy of intervention therapy in different risk stratifications of patients with NSTEMI. Results Interactive item Cox regression analysis and subgroup analysis show that high-risk NSTEMI patients with a GRACE score > 140 points and the time from admission to intervention < 24 h (p = 0.0004) and 24-72 h (p = 0.0143) have interactive effects on the impact of the MACE event with the reference of intervention time > 72 h and GRACE score < 108 points. The time from admission to intervention < 24 h is an independent protective factor for the occurrence of MACE events (HR = 0.166, 95% CI 0.052-0.532, p = 0.0025). Middle-risk patients with NSTEMI with a GRACE score of 109-140 points and the time from admission to intervention < 24 h (p = 0.0370) and 24-72 h (p = 0.0471) have an interactive effect on the impact of MACE. The time from admission to intervention > 72 h is an independent protective factor for the occurrence of MACE (HR = 0.201, 95% CI 0.045-0.897, p = 0.0355). Conclusion The time from admission to intervention < 24 h could effectively reduce the risk of MACE events within 1 year in high-risk patients with NSTEMI (GRACE score > 140 points); the time from admission to intervention > 72 h can reduce the risk of MACE events within 1 year in low-risk patients with NSTEMI (GRACE score ≤ 108 points).

Abstract
Objective: To compare the efficacy and safety of venetoclax (VEN) combined with azacitidine (AZA) versus CAG regimen combined with decitabine (DAC) in elderly patients with relapsed acute myeloid leukemia (AML). Methods: From January 2018 to August 2020, the clinical data of forty-five elderly patients with relapse AML at the First Affiliated Hospital of Soochow University were retrospectively analyzed, including 31 males and 14 females. The median age was 66 (60-80) years old. Eighteen patients were administrated with VEN and AZA, while the other 27 were in CAG with DAC. The complete remission (CR) rate, partial remission (PR) rate, total remission rate (ORR), adverse events and overall survival (OS) were compared between the two groups. Results: At the end of the treatment, the ORR in VEN with AZA group was 77.8% (14/18); including 11 CR and 3 PR. In CAG with DAC group, the ORR was 37.0% (10/27); including 8 CR and 2 PR (P=0.007). Subgroup analysis suggested that VEN with AZA had a higher ORR in patients stratified as intermediate and poor-risk (P=0.013) or with DNA methylation mutations (P=0.007). Main adverse events in both groups were bone marrow suppression, infections, nausea and vomiting, anorexia and fatigue. Grade Ⅲ-Ⅳ cytopenia developed in lower incidence of VEN with AZA group, such as leukopenia (66.7% vs. 100%, P=0.002), anemia (50.0% vs. 92.6%, P=0.002), thrombocytopenia (72.2% vs. 96.3%, P=0.031) and neutropenia (61.1% vs. 92.6%, P=0.014). In addition, less grade Ⅲ-Ⅳ infections occurred in VEN with AZA group (66.7% vs. 33.3%, P=0.028), as well as grade Ⅲ-Ⅳ gastrointestinal events (40.7% vs. 11.1%, P=0.032), grade Ⅲ-Ⅳ fatigue (55.6% vs.11.1%, P=0.003) compared with CAG with DAC group. The 1-year OS in VEN with AZA group versus CAG with DAC group was 42.9% and 31.6% respectively (P=0.150). Conclusion: VEN combined with AZA proves favorable efficacy and tolerablity in elderly patients with relapsed AML.

Effects of Evolocumab Added to Moderate-Intensity Statin Therapy in Chinese Patients With Acute Coronary Syndrome: The EMSIACS Trial Study Protocol. Front Physiol 2021; 12:750872.

Abstract
Background: Several studies have demonstrated that using a higher dose of statin can easily induce liver injury and myopathy. Low-density lipoprotein cholesterol (LDL-C) is a well-established modifiable risk factor for cardiovascular disease; however, the large majority of Chinese patients cannot meet the target level of LDL-C recommended by the Chinese expert consensus. Evolocumab has been demonstrated to reduce LDL-C by approximately 60% in many studies. Nevertheless, whether combined evolocumab and moderate-intensity statin is as effective in lowering LDL-C and decreasing incidence of MACE in Chinese patients presenting with the acute phase of acute coronary syndrome (ACS) remains unknown. Therefore, the "Evolocumab added to Moderate-Intensity Statin therapy on LDL-C lowering and cardiovascular adverse events in patients with Acute Coronary Syndrome" (EMSIACS) is conducted. Methods: The EMSIACS is a prospective, randomized, open-label, parallel-group, multicenter study involving analyzing the feasibility and efficacy of evolocumab added to moderate-intensity statin therapy on lowering LDL-C levels in adult Chinese patients hospitalized for acute phase ACS. The sample size calculation is based on the primary outcome, and 500 patients will be planned to recruit. Patients are randomized in evolocumab arm (evolocumab 140mg every 2weeks plus rosuvastatin 10mg/day or atorvastatin 20mg/day) and statin-only arm (rosuvastatin 10mg/day or atorvastatin 20mg/day). The primary outcome is the percentage change in LDL-C in weeks 4 and week 12 after treatment. The secondary outcome is the occurrence of MACE after 12weeks and 1year of treatment. Discussion: If the EMSIACS trial endpoints prove statistically significant, the evolocumab added to moderate-intensity statin therapy will have the potential to effectively lower subjects' LDL-C levels, especially for the Chinese patients with acute phase ACS. However, if the risk of MACE is not significantly different between the two groups, we may extend follow-up time for secondary outcome when the clinical trial is over. Clinical trial registration: The study is registered to ClinicalTrials.gov (NCT04100434), which retrospectively registered on November 24, 2020.

Abstract
There is little evidence to recommend the optimal invasive mechanical ventilation (IMV) modes and ideal positive end-expiratory pressure stress levels for acute myocardial infarction-cardiogenic shock (AMI-CS) patients. The aim of this study was to compare the mortality outcome in patients with AMI-CS who were treated with percutaneous coronary intervention (PCI) assisted by intra-aortic balloon pump (IABP) + IMV with historical controls. From January 1, 2016 to June 1, 2017, 60 patients were retrospectively enrolled at Tianjin Chest Hospital. Out of these, 88.3% of patients achieved thrombolysis in myocardial infarction (TIMI) flow 3 after PCI. The all-cause mortality rate in-hospital and at 1 year was 25% (95% CI: 0.14–0.36) and 33.9% (0.22–0.46), respectively. A systematic review followed by meta-analysis was performed with four historical studies of patients treated by PCI + IMV with partial IABP, which found an in-hospital mortality rate of 66.0% (95% CI: 0.62–0.71). Recently, a meta-analysis of patients receiving PCI + IABP with partial IMV showed that the 1 year mortality rate was 52.2% (95% CI: 0.47–0.58). In Cox regression analysis of patient data from the current study, lactic acid level ≥4.5 mmol/L, hyperuricemia, and TIMI flow <3 were independent predictors of death at 1 year. All-cause mortality, in-hospital and at 1 year, in patients with AMI-CS treated with PCI + IABP and IMV was lower than in those treated with PCI + partial IABP or IMV. Larger, longer-term direct comparisons are warranted.

Abstract
Saphenous vein grafts disease (SVGD) is a common complication after coronary artery bypass graft (CABG) and usually treated by percutaneous coronary intervention (PCI). In this prospective cohort study, we performed virtual histology-intravascular ultrasound to investigate whether plaque composition and morphological characteristics were associated with post-PCI major adverse cardiac events (MACEs) and slow/no-reflow in patients with SVGD. Patients (n = 90) were studied (76.7% men, mean age 64.9 ± 8.2 years and mean duration of SVG 8.0 ± 3.6 years). There were 77.8% lesions with a plaque burden of at least 70%; 18 MACE incidences accumulated in 14 patients over 12 months post-PCI and slow/no-reflow was observed in 12 patients. On adjusted multivariate analysis, lesion length (hazard ratio [HR] = 1.05; 95% confidence interval [CI]: 1.01-1.08]); age of CABG (HR = 1.51 [95% CI: 1.11-2.05], and absolute necrotic core (NC) area (HR = 8.04 [95% CI: 1.86-34.73]) were independently associated with MACEs. Factors independently associated with slow/no-reflow post-PCI were preprocedure systolic blood pressure (odds ratio [OR] = 0.98; 95% CI: 0.96-0.99) and absolute NC area (OR = 2.47 (95% CI: 1.14-5.36). A cutoff value of absolute NC area at ≥1.1 mm2 may serve as a significant risk predictor for no-reflow after SVG-PCI. Factors associated with MACEs and the slow/no-reflow phenomenon following PCI of the SVG can be used in risk assessment of SVG.

Abstract
Objective: To investigate the features of plaques of saphenous venous graft (SVG) with virtual histology intravascular ultrasound (VH-IVUS) in patients underwent coronary artery bypass graft surgery. Methods: From March 2016 to March 2018, a total of 45 patients ((64.4±7.9) years old, 88.9% male (40 cases)) with ischemic symptoms after coronary artery bypass graft surgery and with coronary artery angiography evidenced SVG stenosis greater than or equal to 50%, who received percutaneous coronary intervention in Tianjin chest hospital were continuously included in this study, and the clinical data were retrospectively analyzed. VH-IVUS was performed before PCI to analyze plaque composition. The patients were divided into no smoking group (21 cases) and smoking group (24 cases), no diabetes group (30 cases) and diabetes group (15 cases), normal very low density lipoprotein cholesterin (VLDL-C) group (24 cases) and elevated VLDL-C group (21 cases), stable angina pectoris group (5 cases) and acute coronary syndrome group (40 cases), plaque burden (PB) < 70% group (11 cases) and PB ≥ 70% group (34 cases), without thin-cap fibroatheroma group (35 cases) and thin-cap fibroatheroma group (10 cases), and plaque features were compared between different groups. Results: The graft age was (8.9±3.7) years.The stenosis degree of SVG lesions was 90 (90, 98) %. The minimum lumen diameter was 1.6 (1.5, 1.8) mm. The vessel cross-sectional area was (12.1±4.0) mm(2). The plaque area was 8.6 (5.7,12.0) mm(2). The minimum lumen area was 2.5 (2.1,3.3) mm(2). The plaque burden was (75.3±8.3)%. The fibrotic tissue (FI) ratio was (65.1±10.1)%, fibrofatty plaque (FF) ratio was 13.8 (5.4,25.3) %, necrotic core tissue (NC) ratio was 12.0 (5.4,24.0)%, and dense calcium tissue (DC) ratio was1.0 (0.2,3.8)% in SVG lesions. There were no significant differences in SVG plaque area, FI area,FF area,NC area,and DC area between no smoking group and smoking group, no diabetes group and diabetes group, and normal VLDL-C group and elevated VLDL-C group. SVG plaque volume was significantly higher in acute coronary syndrome group than in stable angina pectoris group (262.2 (148.5,401.2) mm(3) vs. 93.1 (50.6,155.9) mm(3),P=0.006), and plaque area (10.1 (6.6,13.3) mm(2) vs. 5.0 (3.6,6.9) mm(2), P<0.001), FI area(4.8 (3.2,6.8) mm(2) vs. 2.8 (1.9,3.0) mm(2), P<0.001),and FF area (1.15 (0.60, 2.07) mm(2) vs. 0.30 (0.10,0.90) mm(2), P=0.009) were significantly larger in PB ≥ 70% group than in PB < 70% group.The NC area (1.75(0.40,2.78) mm(2) vs. 0.60 (0.20,1.30) mm(2), P=0.030) and DC area (0.35 (0.10,0.50) mm(2) vs. 0.00 (0.00,0.10) mm(2), P=0.006) were significantly larger in thin-cap fibroatheroma group than that in without thin-cap fibroatheroma group. Spearman correlation analysis showed that the plaque area of SVG lesion was positively correlated with FF area (r=0.64, P<0.001) and NC area (r=0.43, P=0.003). PB was positively correlated with FF area (r=0.50, P<0.001) and NC area (r=0.33, P=0.028). Graft age was positively correlated with FF area (r=0.30, P=0.047). Conclusions: The main components of SVG plaque are fibrotic tissue, conversely, calcified tissue is rare in patients with SVG stenosis after coronary artery bypass graft surgery. Fibrofatty tissue is increased in the plaque in patients with PB ≥ 70%. The necrotic component is also increased in patients with thin-cap fibroatheroma. The fibrofatty component increases and the plaque tends to be unstable in proportion with increaing age of the graft in this patient cohort.

Abstract
Background Plaque composition and morphologic characteristics identified by virtual histology intravascular ultrasound (VH-IVUS) can determine plaques at increased risk of clinical events following percutaneous coronary intervention (PCI) among coronary artery disease (CAD) patients. However, there have been few studies to investigate the relationship between plaque composition of saphenous vein graft (SVG) by VH-IVUS and clinical outcomes in patients with saphenous vein graft disease (SVGD) undergoing PCI. The purpose of this study is to determine whether plaque components and characteristics by VH-IVUS can predict major adverse cardiac events (MACEs) among SVGD patients undergoing PCI. Methods/design This is a prospective cohort study conducted in Tianjin Chest Hospital, China. Participants with SVGD referred for PCI will be invited to participate in this study, and will be followed up at 1, 6, 12, 24 and 36 months post-PCI to assess clinical outcomes. The planned sample size is 175 subjects. We will recruit subjects with SVGD scheduled to receive PCI, aged 18–80 years, with a history of previous coronary artery bypass graft (CABG) surgery more than 1 year ago, and willing to participate in the study and sign informed consent. The composite primary study endpoint is the incidence of MACEs after PCI for SVGD, including death from cardiac causes, non-fatal myocardial infarction, unplanned target lesion revascularization (TLR) and target vessel revascularization (TVR). The primary outcome analysis will be presented as Kaplan-Meier estimates and the primary outcome analysis will be carried out using a Cox proportional hazards regression model. Discussion Once the predictive values of plaque components and characteristics by VH-IVUS on subsequent clinical outcomes are determined among SVGD patients undergoing PCI, an innovative prediction tool of clinical outcomes for SVGD patients undergoing PCI will be created, which may lead to the development of new methods of risk stratification and intervention guidance. Trial registration The study is registered to ClinicalTrials.gov (NCT03175952).

Abstract
Objective: To compare the bioequiavailability of paclitaxel for injection (albumin bound) (PAB) and reference listed drug abraxane in the patients with metastatic breast cancer, and to investigate the safety and efficacy in the extension treatments of PAB. Methods: This study was random, two cycles, self-crossover control study in the bioequiavailability stage. PAB was the investigational drug T and Abraxane was the reference drug R. Patients were randomly assigned to two cycles therapy of either R→T or T→R(260 mg/m(2)/21d). Non-PD patients entered in the extension treatments of the investigational drug PAB(260 mg/m(2)/21d) until the disease progression or the intolerance toxicity. Results: From Mar 1, 2016 to May 24, 2016, we enrolled 40 patients. The blood concentration-time curve and the parameters of pharmacokinetics indicated the two drugs were the bioequivalent drug products in the initial two cycles crossover-therapy.The incidence of adverse drug reactions were 89.7% vs 97.4% in investigational drug vs reference drug and grade 3/4 toxicities were 20.5% vs 21.1%(P=1.000). Patients received a median of 7 treatment cycles(range 1-23) and a median of 260mg/m(2) actual drug dose (range 220-260 mg/m(2)). Seven patients (17.5%) had dose reductions because of toxicities (260 mg/m(2) reduce to 220 mg/m(2)). Twenty-two patients (55%) discontinued treatment prematurely because of toxicity.Overall response rates (ORR) were 40% (95% CI, 24.8%-55.2%). For patients who received PAB as first-line vs non-first-line therapy, the ORR were 43.8% vs 25%. For patients who taxane-naïve vs taxane-pretreated, the ORR were 45.5% vs 37.9%. Median PFS was 49 weeks(95% CI, 30weeks-NA). Conclusion: The paclitaxel for injection (albumin bound) (PAB) and reference listed drug abraxane are the bioequivalent drug products.The toxicity and efficacy of the PAB are similar with abraxane.The more therapy chances for Chinese patients will come by the research and development of domestic drugs.

Abstract
The objective of this study was to investigate whether nitrous oxide influenced the ED50 of sevoflurane for induction of isoelectric electroencephalogram (ED50isoelectric ) differently from its influence on the ED50 of sevoflurane for electroencephalogram burst suppression (ED50burst ). In a prospective, randomised, double-blind, parallel group, up-down sequential allocation study, 77 ASA physical status 1 and 2 patients received sevoflurane induction and, after tracheal intubation, were randomly allocated to receive sevoflurane with either 40% oxygen in air (control group) or 60% nitrous oxide in oxygen mixture (nitrous group). The ED50isoelectric in the two groups was determined using Dixon's up and down method, starting at 2.5% with 0.2% step size of end-tidal sevoflurane. The electroencephalogram was considered as isoelectric when a burst suppression ratio of 100% lasted > 1 min. The subsequent concentrations of sevoflurane administered were determined by the presence or absence of isoelectric electroencephalogram in the previous patient in the same group. The ED50isoelectric in the nitrous group 4.08 (95%CI, 3.95-4.38)% was significantly higher than that in the control group 3.68 (95%CI, 3.50-3.78)% (p < 0.0001). The values for ED50burst were 3.05 (95%CI, 2.66-3.90)% and 3.02 (95%CI, 3.00-3.05)% in nitrous group and control group, respectively (p = 0.52). The addition of 60% nitrous oxide increases ED50isoelectric , but not the ED50burst of sevoflurane. Neither result indicates an additive effect of anaesthetic agents, as might be expected, and possible reasons for this are discussed.

Abstract
The dual-luciferase reporter assay is widely used for microRNA target identification and the functional validation of predicted targets. To determine whether curcumin regulates expression of the histone methyltransferase enhancer of zeste homolog 2 (EZH2) by targeting its 3′untranslated region (3′UTR), two luciferase reporter systems containing exactly the same sequence of the EZH2 3′UTR were used to perform dual-luciferase reporter assays. Surprisingly, there were certain discrepancies between the luciferase activities derived from these two reporter constructs. We normalized luciferase activity to an internal control to determine the amount of the reporter construct successfully transfected into cells, induced a transcriptional block with flavopiridol, quantified renilla luciferase mRNA levels, and compared the absolute luciferase activity among the different groups. The results suggested that curcumin promoted the transcription of the luciferase genes located downstream of the simian vacuolating virus 40 (SV40) early enhancer/promoter, but not those located downstream of the human cytomegalovirus (CMV) immediate-early or the herpes simplex virus thymidine kinase (HSV-TK) promoters. These results explain the discrepancies between the two luciferase reporter systems. The current study underscores the importance of taking caution when interpreting the results of dual-luciferase reporter assays and provides strategies to overcome the potential pitfall accompanying dual-luciferase reporter systems.

Abstract
Nucleophosmin/B23 (NPM) is a universally expressed nucleolar phosphoprotein that participates in proliferation, apoptosis, ribosome assembly, and centrosome duplication; however, the role of NPM in cell cycle regulation is not well characterized. We investigated the mechanism by which NPM is involved in cell cycle regulation. NPM was knocked down using siRNA in HepG2 hepatoblastoma cells. NPM translocation following actinomycin D (ActD) treatment was investigated using immunofluorescent staining. Expression of NPM and other factors involved in cell cycle regulation was examined by Western blotting. Cell cycle distribution was measured using flow cytometry to detect 5-ethynyl-2'-deoxyuridine (EdU) incorporation. Cell proliferation was quantified by the MTT assay. Knockdown of NPM increased the percentage of HepG2 cells in S phase and led to decreased expression of P53 and P21Cip1/WAF1. S-phase arrest in HepG2 cells was significantly enhanced by ActD treatment. Furthermore, knockdown of NPM abrogated ActD-induced G2/M phase cell cycle arrest. Taken together, these data demonstrate that inhibition of NPM has a significant effect on the cell cycle.

Abstract
OBJECTIVE To investigate the effectiveness of microinvasive Nd:YAG laser therapy in human glottic Tis and T1 carcinomas, as well as its effect on the cellular immune function of the tumor-bearing hosts. STUDY DESIGN We treated 34 patients with microinvasive Nd:YAG laser therapy and evaluated its effect on the cellular immune function of the host. METHODS Thirty-four patients with glottic Tis or T1 squamous cell carcinoma were treated with fiberoptic laryngoscopic Nd:YAG laser surgery. Both before and after therapy, serum levels of soluble interleukin-2 receptor (SIL-2R) and interleukin-2 (IL-2), as well as natural killer (NK) cell activity, were determined by means of double-antibody sandwich technique, tritiated thymidine-deoxyribonucleoside incorporation, and iodine 125-uridine-deoxyribonucleoside release technique, respectively. RESULTS All 34 patients tolerated the procedure well. A 3- to 7-year follow-up in a subgroup of 27 patients resulted in an estimated cure rate of 85.2% (23 of 27 patients). In all 27 patients with a regular follow-up, a subjective improvement of phonation was noted after therapy to various degrees. In 74% (20 of 27 patients), voice and speech subjectively recovered to almost normal levels. The post-therapy serum levels of SIL-2R were significantly declined (P <.001), whereas those of IL-2 and the NK activity were significantly elevated (P <.001) as compared with those detected before therapy. CONCLUSIONS Therapy with fiberoptic laryngoscopic Nd:YAG laser surgery is simple, safe, effective and only minimally invasive for patients with glottic Tis or T1 carcinoma. At the same time, it has an immunoenhancing effect on its host.

Abstract
OBJECTIVE To define the expression levels of MDM2 gene in nasopharyngeal carcinoma (NPC) and its relationship with p53 protein expression and EB virus latent infection. METHOD MDM2 gene expression at mRNA and protein levels, p53 protein and EB virus DNA were detected by nonradioactive in situ hybridization (ISH), immunohistochemistry(IHC) and polymerase chain reaction (PCR) separately in 46 cases of NPC tissues and 12 cases of chronic inflammation of nasopharyngeal epithelium (CINE). RESULT Fourteen cases of NPC showed MDM2 mRNA and protein overexpression, 38 cases were p53 protein positive, and 43 cases were EBV-DNA positive. Neither MDM2 nor p53 protein was expressed in any case of CINE. MDM2 expression was significantly related to p53 protein expression (P < 0.05), but not to EB virus latent infection in NPC. CONCLUSION MDM2 gene may play an important role in the pathogenesis of NPC through interacting with p53 protein.

Abstract
From January 1992 to November 1994, 163 patients with nasopharyngeal carcinoma (NPC) were prospectively randomized into three groups: standard radiotherapy (SRT) group, external irradiation and after-load intracavitary radiation in combination with traditional Chinese medicine (EIAIRC) group, and external irradiation plus traditional Chinese medicine (EIC) group. All patients were treated with usual radiotherapy. The nasopharynx's radiation dose was 50-60 Gy, intracavitary irradiation 16 Gy/2 times (The distance from radiation source to spot of reference was 14 mm away). The radiation dose in EIC and SRT group was 68-72 Gy, respectively. The results were as follows: 1. There were no statistical difference among the three groups in 3-year or 5-year survival rate and no local relapse or distant metastasis. 2. The TCM alleviated the acute radiation reaction and damage effects. It indicates that the therapy might decrease radiation dose and the TCM does not induce NPC distant metastasis.

Abstract
MDM2 gene amplification and overexpression were detected by DNA dot blot analysis and reverse transcription-polymerase chain reaction (RT-PCR) in 32 cases of nasopharyngeal carcinoma (NPC), 10 cases of chronic inflammation of nasopharyngeal epithelium(CINE) and NPC cell line HONE1. One case of NPC showed MDM2 gene amplification, NPC cell line HONE1 and ten cases of NPC showed MDM2 mRNA overexpression. No MDM2 gene amplification and overexpression were found in CINE. MDM2 mRNA overexpression was significantly related to cervical lymph node metastasis, but not to T stage of NPC. The results indicate that MDM2 gene may play an important role in the pathogenesis and the process of metastasis of NPC.

Abstract
Hearing impairment is the most commonly occurring condition that affects the ability of humans to communicate. More than 50% of the cases of profound early-onset deafness are caused by genetic factors. Over 40 loci for non-syndromic deafness have been genetically mapped, and mutations in several genes have been shown to cause hearing loss. Mutations in the gene encoding connexin 26 (GJB2) cause both autosomal recessive and dominant forms of hearing impairment. To study the possible involvement of other members of the connexin family in hereditary hearing impairment, we cloned the gene (GJB3) encoding human gap junction protein beta-3 using homologous EST searching and nested PCR. GJB3 was mapped to human chromosome 1p33-p35. Mutation analysis revealed that a missense mutation and a nonsense mutation of GJB3 were associated with high-frequency hearing loss in two families. Moreover, expression of Gjb3 was identified in rat inner ear tissue by RT-PCR. These findings suggest that mutations in GJB3 may be responsible for bilateral high-frequency hearing impairment.

Abstract
We determined pre- and post-photodynamic therapy (PDT) serum levels of soluble interleukin-2 receptor (SIL-2R) and interleukin-2 (IL-2), as well as activity of natural killer (NK) cells, among 24 patients with either persistent or recurrent nasopharyngeal carcinoma (NPC), using a double-antibody sandwich technique, tritiated thymidine-deoxyribonucleoside incorporation, and iodine 125-uridine-deoxyribonucleoside release techniques, respectively. The results showed that the post-PDT serum level of SIL-2R had significantly declined (p < .0005), while that of IL-2 and the NK cell activity had significantly increased (p < .0005), compared with pre-PDT values, suggesting an immunoenhancing effect of PDT on NPC patients.

Abstract
The unclear DNA content was measured with flow cytometry (FCM) in 167 specimens of normal nasopharyngeal epithelium (NE), adjacent tissue to carcinoma (ATC) and nasopharyngeal carcinoma (NPC). All 20 patients with NE showed diploid, whereas 38 (38%) of 101 patients with NPC, 7 (58%) of 12 patients with recurrent NPC, 6 (30%) of 20 patients with ATC and 2 (33%) of 6 patients with NE, positive to EBVCA-IgA test, showed nondiploid. In addition, cellular proliferation index (PI) of diploid NPC and diploid ATC, though differed nonsignificantly, was significantly increased as compared with that of NE (P < 0.01). The rate of cervical metastasis in nondiploid NPC was significantly higher than that in diploid NPC (P < 0.025).

Abstract
Both animal tumors and human nasopharyngeal carcinoma were submitted to a photoradiation therapy (PRT) trial in order to determine the efficacy and side effects of PRT, as well as to elucidate its mechanism of cytotoxicity. In animal tumors, the inhibition rate was 70%, and of 20 patients, eight achieved complete remission, and ten, significant remission, with an overall response rate of 90%. The blood picture and the values of serum IgG, IgM, IgA, and C3 all remained stable post-PRT. Only three patients developed mild generalized skin photosensitive reactions, and these did not affect subsequent treatment. There was no immunosuppressive effect as evidenced by a tritium-labeled thymidine-incorporated lymphocytoblast transformation assay performed both before and after PRT. Ultrastructural studies at different time intervals after PRT highly suggested that the mitochondria and rough endoplasmic reticulum were among the first organelles to be damaged.
