[Analysis of the clinical predictive value of lactate on the prognosis of patients with acute-on-chronic liver failure combined with infection].

Objective: To explore the predictive value of lactic acid for the adverse prognostic outcomes in patients with acute-on-chronic liver failure combined with infection. Methods: A retrospective analysis was conducted on the clinical data of 208 cases of ACLF combined with infection who were hospitalized from January 2014 to March 2016. Patients were divided into a survival group (n = 83) and a mortality group (n = 125) according to the results of a 90-day follow-up. The clinical data were statistically analyzed between the two groups. Multivariate logistic regression with two categorical variables was used to analyze the independent risk factors for 90-day disease mortality and establish a new prediction model. The receiver operating characteristic curve (ROC curve) was used to evaluate the predictive value of lactic acid, the MELD score, the MELD-Na score, lactic acid combined with the MELD score, lactic acid combined with the MELD-Na score, and the new model. Results: The 90-day mortality rate of 208 cases of ACLF combined with infection was 60.1%. There were statistically significant differences in white blood cell count, neutrophil count, total bilirubin (TBil), serum creatinine (Cr), blood urea nitrogen (BUN), blood ammonia, the international normalized ratio (INR), lactic acid (LAC), procalcitonin, the MELD score, the MELD-Na score, hepatic encephalopathy (HE), acute kidney injury (AKI), and bleeding between the two groups. Multivariate logistic regression analysis showed that TBil, INR, LAC, HE, and bleeding were independent risk factors for 90-day mortality in patients with ACLF combined with infection. After the establishment of MELD-LAC, MELD-Na-LAC, and a new prediction model, the ROC curve revealed that the AUC (95% confidence interval) of MELD-LAC and MELD-Na LAC were 0.819 (0.759 ~ 0.870) and 0.838 (0.780 ~ 0.886), respectively, and was superior than the MELD score [0.766 (0.702 ~ 0.823)] and MELD-Na score [0.788 (0.726 ~ 0.843)], with P < 0.05, while the new model had an AUC of 0.924, the sensitivity of 83.9%, specificity of 89.9%, and accuracy of 87.8%, which was higher than LAC, MELD score, MELD-Na score, MELD-LAC, and MELD-Na-LAC (P < 0.01). Conclusion: Lactic acid is an independent risk factor for mortality in patients with ACLF combined with infection, and it improves the clinical predictive value of MELD and MELD-Na for the prognosis of mortality.

[The outcomes of Tiantan first-aid protocol on critically ill patients with primary central nervous system lymphoma].

Objective: To examine the outcomes of Tiantan first-aid protocol on critically ill patients with primary central nervous system lymphoma (PCNSL). Methods: The clinical data of 18 patients with PCNSL who were treated according to Tiantan first-aid protocol at Department of Neurosurgery,Beijing Tiantan Hospital, Capital Medical University from November 2019 to December 2021 were retrospectively analyzed. There were 9 males and 9 females, aged (56.9±11.1)years (range: 29 to 77 years). The median Karnofsky performance status(KPS) score at admission was 40 (range: 20 to 60). Three patients were mild coma, 3 were lethargy and 12 were conscious. The mean midline shift was 0.7 cm (range: 0 to 1.8 cm). After admission, all patients were treated according to the plan of rapid biopsy, rapid routine pathology and rapid salvage chemotherapy. The treatment procedures, clinical and radiographic outcomes, KPS score and adverse reactions of patients after chemotherapy were collected. Results: All of the 18 patients completed the first-aid treatment. The median duration from admission to the biopsy was 1 day (range: 0 to 5 days), from biopsy to routine pathological diagnosis was 1 day (range: 1 to 4 days) and from routine pathology to salvage chemotherapy was 1 day (range: 0 to 4 days). All the patients were pathologically confirmed with diffuse large B cell lymphoma, 1 patient was double-hit lymphoma. Seventeen patients underwent clinical remission and 1 died of cardiac dysfunction. The successful salvage rate was 17/18. Radiologically, complete remission was observed in 1 case, partial remission in 16 cases, and stable disease in 1 case. The median KPS score at discharge was 60 (range: 30 to 80). The mild gastrointestinal, hematological and hepatic adverse effects were observed after chemotherapy. Conclusion: Tiantan first-aid protocol is effective for critically ill patients with PCNSL, which has the merit to be popularly used and improved.

[Five-year clinical outcomes of patients with in-stent chronic total occlusion undergoing percutaneous coronary intervention].

Objective: To evaluate the safety and long-term clinical efficacy of percutaneous coronary intervention (PCI) in patients with in-stent chronic total occlusion (IS-CTO) lesions. Metheds: This is a retrospective analysis. Patients with IS-CTO who underwent PCI in Fuwai hospital from January 2010 to December 2013 were enrolled. A total of 212 patients who met the inclusion criteria were included in the IS-CTO group, 212 matched patients with primary CTO lesions were included in the de novo CTO group. The incidence of complications and the success rate of PCI were compared between the two groups. Successful PCI was defined as successfully implantation of stent(s) at target CTO lesions. The primary endpoint was defined as a composite event of cardiac death and myocardial infarction (MI). Secondary endpoints including PCI success, all-cause death, cardiac death, MI, target vessel related MI, revascularization, target vessel revascularization, heart failure for rehospitalization. The patients were followed up for 5 years after PCI. Results: A total of 424 cases were included. The mean age was (57.8±10.5) years, there were 364 males in this cohort. The left ventricular ejection fraction was significantly lower ((58.7±9.2)% vs. (61.0±7.7)%, P=0.01) and the SYNTAX scores was significantly higher (19.4±8.3 vs. 15.3±10.0, P<0.01) in IS-CTO group than that in de novo CTO group. The proportion of patients with target CTO lesions in left anterior descending artery was significantly higher (42.9% (50/212) vs. 23.6% (91/212), P<0.01) in IS-CTO group than that in de novo CTO group. The rate of successful PCI (71.7% (152/212) vs. 69.8% (148/212), P=0.70) and complication (40.6% (86/212) vs. 36.3% (77/212), P=0.37) was similar between the two groups. The incidence of primary endpoint at 5 years was significantly higher in IS-CTO group (10.8% (23/212) vs. 4.7% (10/212), P=0.02), which was driven by higher incidence of MI (9.0% (19/212) vs. 4.2% (9/212), P=0.05). There were a trend of higher secondary endpoints in IS-CTO group (all P>0.05). Conclusion: The safety and effectiveness of PCI are acceptable in patients with IS-CTO, but the risk of long-term cardiac death and MI is higher among patients with IS-CTO as compared to patients with primary CTO lesions.

[The safety and efficacy of Firesorb bioresorbable scaffold in first-in-man study for coronary artery disease: the four-year outcomes].

Objective: To evaluate the 4-year clinical outcomes of patients following Firesorb bioresorbable scaffold (BRS) implantation. Methods: The study reported the 4-year follow-up results of the FUTURE I study. FUTURE I was a prospective, single-center, open-label, first-in-man study which evaluated the feasibility, preliminary safety, and efficacy of Firesorb stent in the treatment of coronary artery stenosis. A total of 45 patients with single de novo lesions in native coronary arteries ,who hospitalized in Fuwai Hospital from January to March 2016 were enrolled. After successfully stent implantation these patients were randomized in a 2∶1 ratio into cohort 1 (n=30) or cohort 2 (n=15). The patients in cohort 1 underwent angiographic, IVUS or OCT examination at 6 months and 2 years; and cohort 2 underwent angiographic, IVUS or OCT at 1 and 3 years. All patients underwent clinical follow-up at 1, 6 months and 1 year and annually thereafter up to 5 years. The primary endpoint was target lesion failure (TLF, including cardiac death, target vessel myocardial infarction, and ischemia-driven target lesion revascularization). Secondary endpoints included patient-oriented composite endpoint (PoCE, defined as composite of all death, all miocardial infarction, or any revascularization). Results: A total of 45 patients were enrolled and implanted with Firesorb BRS, including 35 males (77.8%), and the age was (54.4±9.3) years. At 4 years, 10 patients in cohort 1 were reexamined by coronary angiography and OCT examination. Among them, 2 patients' stents were completely degraded and absorbed. Compared with the OCT images of the other 8 patients in cohort 2 at 3 years, the degree of stent degradation was increased, and no stent adherence was found. The 4-year clinical follow-up rate was 100%. In 4-year clinical following up, 2 patients suffered PoCE (4.4%): 1 patient underwent non-target vessel revascularization the day after index procedure and target vessel revascularization (Non-target lesion revascularization) at 2-year imaging follow-up; the other patient underwent target lesion revascularization during imaging follow-up at 4 years but not due to ischemic driven. There was no scaffold thrombosis or TLF events through 4 years. Conclusions: Four years after the implantation, complete degradation and absorption of the Firsorb stent are evidenced in some patients. Firesorb stent is feasible and effective in the treatment of patients with non-complex coronary lesions.

[Clinical characteristics of infection-induced acute renal injury in acute-on-chronic liver failure].

Objective: To investigate the incidence rate, influencing factors and prognosis of infection-induced acute renal injury (AKI) in patients with acute-on-chronic liver failure (ACLF). Methods: 516 cases with acute-on-chronic liver failure complicated with infection that were hospitalized in our hospital during 2014 to 2016 were retrospectively studied. General conditions and clinical characteristics of the patients were collected, and grouped according to the presence or absence of incidence and severity of AKI. General conditions, laboratory results, occurrence of complications and survival were compared and analyzed. Results: The main causes were HBV infection (67.8%) and alcoholic liver disease (20.0%). The most common sites of infection were abdominal cavity, lung and blood. Multivariate analysis showed that neutrophil count, TBIL, lactate and septic shock were independent risk factors for infection-induced AKI in ACLF patients. The cumulative mortality in patients with AKI after infection at 28, 90 and 360 days was significantly higher than those without AKI (51.6% and 20.5%, 70.2% and 40.3%, 73.4% and 45.9%; P < 0.01). In both groups, deaths had occurred mainly in the early (0 ~ 28 d) and middle (29 ~ 90 d) stage of follow-up period. In the late follow-up period (91-360 d), there was no statistically significant difference in mortality rate between the two groups. Conclusion: Infection is an important inducing cause of AKI in ACLF patients. The underlying liver disease and the severity of infection are significantly related to the infection-induced AKI in ACLF patients, and once AKI occurs after infection, the mortality rate of the patients is significantly increased.

[Association between lipoprotein (a) level and chronic cardio-renal syndrome in elderly patients].

Objective: To explore the relationship between lipoprotein(a) [Lp(a)] and chronic cardio-renal syndrome (CRS) in elderly patients. Methods: Chronic heart failure (CHF) patients age ≥ 65 years old, who hospitalized in the department of Cardiology of Hebei General Hospital from December 2017 to October 2019, were included in this study. According to the estimate glomerular filtration rate (eGFR) level, patients were divided into CRS group (eGFR<60 ml·min-1·1.73 m-2) and CHF group (eGFR ≥60 ml·min-1·1.73 m-2). The blood index and basic disease information were collected and compared. Left ventricular ejection fraction (LVEF) were measured by echocardiography. The correlation between clinical indicators and cardio-renal function (LVEF and eGFR) was assessed. The multivariate logistic regression analysis was used to evaluate the related risk factors of CRS in elderly patients; subgroup logistic regression analysis was performed according to the basic disease of patients to assess the relationship between Lp(a) and CRS. Results: A total of 172 elderly patients (85 males (49.4%), aged 79 (71, 84) years) were finally enrolled. Among them, 88 cases (51.2%) were in CRS group and 84 cases (48.8%) were in CHF group. Age (80 (74, 84) years old vs. 74 (70, 82) years old) and LP (a) levels (222.0 (112.0, 445.3) mg/L vs. 155.0 (97.0, 348.7) mg/L) were significantly higher in the CRS group than in the CHF group (P<0.05). Lp(a) levels were negatively correlated with LVEF (r=-0.155, P=0.043) and eGFR (r=-0.220, P=0.004) in total cohort. In the subgroup analysis of patients with 2 high-incidence basic diseases (coronary heart disease and hypertension), Lp(a) was negatively correlated with LVEF (r=-0.250, P=0.007) in the coronary heart disease group, and negatively correlated with eGFR (r=-0.233, P=0.013) in the hypertension group. Multivariate logistic regression analysis showed that age (OR = 1.069, 95%CI: 1.017-1.124, P= 0.009) and Lp(a) (OR = 3.719, 95%CI: 1.339-10.326, P = 0.012) were independent correlates of CRS. The results of logistic regression analysis showed that Lp(a) was an independent correlative factor of CRS in the subgroups of coronary heart disease (OR=3.207, 95%CI: 1.129-9.108, P=0.029) and hypertension (OR=3.054, 95%CI: 1.086-8.587, P=0.034). Conclusion: Serum Lp(a) level is independently related with CRS in elderly patients.

[Long-term outcomes of patients with ST-elevation myocardial infarction undergoing early versus late delayed percutaneous coronary intervention using drug-eluting stents].

Objective: To compare the long-term outcomes in ST-elevation myocardial infarction (STEMI) patients who underwent early or late delayed percutaneous coronary intervention (PCI) using drug-eluting stents (DES). Methods: This study was a retrospective, observational and single-center study. Consecutive STEMI patients (n=977), who admitted to Fuwai Hospital in 2013 and underwent successful selective PCI using drug-eluting stents (DES) within 3 to 35 days after symptom onset were enrolled and divided into the early delayed PCI (3-14 d) group (n=495) and the late delayed PCI (15-35 d) group (n=482). General clinical data of the patients and related data of coronary angiography and interventional therapy were collected, and the endpoint events were followed up. The primary endpoint was 2-year major adverse cardiac and cerebrovascular events (MACCE) including cardiac death, recurrent myocardial infarction, definite or probable stent thrombosis and ischemic stroke. The secondary endpoint was 2-year ischemia-driven target vessel revascularization. The incidence of endpoint events of the two groups was compared, and it was compared again after the primary baseline characteristics such as age and gender were matched by the propensity scoring method at a 1∶1 ratio. Results: A total of 910 (93.1%) patients who underwent delayed PCI were transferred from other hospitals, and 292 (29.9%) patients received thrombolysis before PCI. The time interval before PCI was 14 (10, 20) days. The incidence of 2-year MACCE (3.0%(15/495) vs. 2.3%(11/482), P=0.468) and ischemia-driven target vessel revascularization (3.8%(19/495) vs. 5.0%(24/482), P=0.385) were similar between the two groups. The incidence of 2-year MACCE (3.3%(15/453 vs. 2.4%(11/453), P=0.426) and ischemia-driven target vessel revascularization (4.2% (19/453) vs. 4.9%(22/453), P=0.632) were also similar between the two groups after matching propensity score. Conclusion: The long-term clinical outcomes after early delayed PCI using DES is statistically equivalent to those of late delayed PCI using DES for STEMI patients who missed the time window for emergency PCI.

Research Progress on Multiple Organ Damage and Mechanism of Cantharidin Poisoning.

ABSTRACT: Cantharidin poisoning has been proven to cause multiple organ damage. Acute circulatory failure, acute renal failure, and multiple organ failure resulting from cantharidin poisoning are the main causes of death for patients with cantharidin poisoning. However, research on the damage of main target organs and mechanism of cantharidin poisoning is not clear. This paper reviews the latest toxicological and pathological research literatures at home and abroad related to cantharidin poisoning and comprehensively summarizes the latest research progress on the toxicological and pathological damage and mechanism of the digestive system, circulatory system, respiratory system, urinary system, reproductive system, skin mucosa, immune system, and nervous system after cantharidin poisoning, to provide reference for improving the molecular toxicological mechanism of cantharidin poisoning and decision-making in the clinical intervention of cantharidin poisoning.

In-fiber Mach-Zehnder interferometer with piecewise interference spectrum based on hole-assisted dual-core fiber for refractive index sensing: erratum.

This erratum is presented to correct Fig. 3 in [Opt. Express26(15), 19091 (2018)].

In-fiber Mach-Zehnder interferometer with piecewise interference spectrum based on hole-assisted dual-core fiber for refractive index sensing.

We demonstrate theoretically and experimentally a novel in-fiber Mach-Zehnder interferometer (MZI) with piecewise interference spectrum. The interferometer is constructed by splicing a short section of single eccentric hole-assisted dual-core fiber (SEHADCF) to two single mode fibers (SMFs) with a lateral-offset. Due to the offset splicing and the small distance between cores, different core modes in two cores of the SEHADCF can be excited to form interference at the different wavelength ranges. The discontinuous region of the interference spectrum can be employed as a mark to identify the order of the interference valley. The in-fiber MZI is experimentally investigated as a refractive index sensor, the sensitivity of 353.9 nm/RIU is obtained in the RI range of 1.335 ~1.395. The in-fiber MZI with a high sensitivity has a great potential in biological and chemical applications. Especially, due to the ability to identify the order of interference valleys by the discontinuous region, the proposed in-fiber MZI can improve the reliability of fiber sensors in remote monitoring applications.

Psychology of cross cultural communication: an impact on the health care system.

Cross culture communication has become an integral part of today's world, especially in developed countries with a large population of immigrants. The health care system is one of the important areas in which health care practitioners and patients may be of different cultures, therefore there is a need of effective communication between culturally different patients and health practitioners. However, cross-culture communication is affected by psychological factors related to cultures and mind-set. Acculturation orientation is one of the important factors, and people with different orientations interact differently with people of different cultures. Cultural orientation is another important factor is which different domains define the characteristic features of different cultures. Moreover, the inclination to use native or non-native language with culturally different patients is a key factor for establishing a good relationship between patients and health care practitioners.

Effect of premedication on lesion detection rate and visualization of the mucosa during upper gastrointestinal endoscopy: a multicenter large sample randomized controlled double-blind study.

BACKGROUND: Premedication in upper gastrointestinal endoscopy for higher lesions detection rate has not been well studied so far. This study aimed to confirm whether premedication could improve the detection rate of early cancer or precancerous lesions and mucosal visibility. METHOD: From July 2015 to December 2015, 7200 participants from 6 centers were screened by endoscopy with one of the 4 following premedications randomly: (1) water (group D); (2) pronase (group A); (3) simethicone (group B); (4) pronase and simethicone (group C). Early cancer and precancerous lesions detection rates were taken as the primary endpoints, and mucosal visibility was taken as the secondary endpoint. They were compared among four groups to determine different premedication effects in terms of different anatomical sites. Trial was registered at Chinese Clinical Trial Registry; the registration number is ChiCTR-IOR-17010985. RESULTS: The upper gastrointestinal overall precancerous lesion detection rates among four groups were 8.7, 8.4, 10.0, and 10.3%, the overall early cancer detection rates were 1.3, 1.4%, 1.5, and 1.6%, both without significant difference (p = 0.138 and 0.878). However, the visibility score distributions between control group (D) and premedication groups (A, B, and C) were all statistically significant, with all anatomical sites p values < 0.001. Subgroup analyses, from 2 centers without screening before, also showed significant difference in esophageal (3.9, 3.3, 4.5, and 8.4% with p = 0.004) and overall (7.0, 5.5, 7.3, and 12.0% with p = 0.004) precancerous lesion detection rate. CONCLUSIONS: Premedication with pronase and simethicone may not increase lesion detection rates but could significantly increase the upper gastrointestinal mucosal visibility.

MiRNA-500a-3p inhibits cell proliferation and invasion by targeting lymphocyte antigen 6 complex locus K (LY6K) in human non-small cell lung cancer.

LY6K (lymphocyte antigen 6 complex locus K) is an anti-gene in non-small cell lung cancer (NSCLC) and miR-500a-3p promotes the progression of cancers. Evidence shows that the increase of miR-500a-3p caused LY6K to be suppressed. Here we hypothesized that miR-500a-3p may take part in the progression of NSCLC through targeting LY6K. miR-500a-3p expression levels in NSCLC specimens and cell lines were detected by quantitative real-time PCR (qRT-PCR). The mRNA and protein expression levels of LY6K in NSCLC specimens and cell lines were examined by qRT-PCR, immunohistochemistry and western blotting. Dual-luciferase reporter assay was carried out to assess miR-500a-3p binding to LY6K gene. The functions of miR-500a-3p and LY6K in proliferation/invasion and lung metastasis formation were assessed by CCK8, Transwell assay and subcutaneous tumor model in nude mice, respectively. Statistical analysis was performed to explore the clinical correlation between miR-500a-3p/LY6K expression and clinicopathological features. miR-500a-3p was substantially decreased in NSCLC tissues and cell lines. LY6K protein and mRNA level expressions were increased in NSCLC patients. Clinical analysis indicated that miR-500a-3p and LY6K were related to tumor differentiation, lymph node metastasis and TNM staging in NSCLC patients. MiR-500a-3p suppresses cell proliferation, invasion and metastasis formation in vivo by targeting the LY6K. miR-500a-3p acts as a tumor suppressor in NSCLC partially via down-regulation of LY6K expression and for NSCLC intervention and suggests a potential therapeutic target for NSCLC intervention.

Effect of matrine on reducing damage to bovine mammary epithelial cells induced by Staphylococcus aureus alpha-hemolysin.

Taking bacterial virulence factors as targets is a new therapy for treating host bacterial infection. The aim of this study was to investigate the effect of matrine on α-hemolysin production of Staphylococcus aureus (S. aureus) and reducing the damage to bovine mammary epithelial cells (BMECs) induced by S. aureus α-hemolysin. Subinhibitory concentrations of matrine decreased the production of α-hemolysin in none dose-dependent manner and matrine exhibited a protective effect on S. aureus-induced BMECs injury. The results indicated that the structure of matrine may potentially be used as a basic structure for development of drugs aimed at curing and preventing dairy bovine mastitis.

[Prognostic value of SYNTAX score on 1 year outcome in patients underwent percutaneous coronary intervention].

Objective: To investigate the prognostic value of SYNTAX score on 1 year outcome in coronary heart disease patients underwent percutaneous coronary intervention(PCI). Methods: The present study (PANDA Ⅲ trial) was a perspective, multi-center, randomized controlled trial. Between December 2013 and August 2014, 2 348 patients who underwent PCI from 46 centers were enrolled. SYNTAX score was calculated from all patients. Patients were divided into 3 groups based on SYNTAX score: lower risk group (SYNTAX score≤22, 1 777 patients), intermediate risk group (SYNTAX score 23-32, 412 patients), and higher risk group (SYNTAX score≥33, 159 patients). The patients were followed up after the procedure for one year.Primary endpoint was target lesion failure (TLF), including cardiac death, target vessel myocardial infarction,and ischemia driven target lesion revascularization. Secondary endpoints included stent thrombosis and major adverse cardiac events were defined as a composite of all-cause death, myocardial infarction and any revascularization. Results: (1) A total of 1 766 (99.2%), 411 (99.8%),and 159 (100%) patients in the lower risk group, intermediate risk and higher risk group completed the 1 year follow up. (2) Incidence of TLF were 5.6%(99/1 763) in lower risk group, 8.8%(36/411) in intermediate risk group,and 8.8%(14/159) in higher risk group(P=0.03). The incidence of target vessel myocardial infarction in lower risk group was 3.9%(68/1 763), 6.6%(27/411) in intermediate risk group,and 7.5% (12/159) in higher risk group(P=0.01).Prevalence of cardiac death and ischemia driven target lesion revascularization was similar among the 3 groups(P>0.05).(3) The probable stent thrombosis events rate was 0.1% (1/1 763), 0.7% (3/411), and 0.6% (1/159) in the lower, intermediate,and higher risk groups respectively (P=0.02). The incidence of major adverse cardiac events was 8.1% (142/1 763) in lower-risk group, 11.7% (48/411) in intermediate risk group, and 14.5% (23/159) in higher risk group (P<0.01). The incidence of all-cause death was 1.7%(30/1 763) in lower-risk group, 1.7%(7/411) in intermediate risk group, and 6.3%(10/159)in higher risk group (P<0.01). The incidence of myocardial infarction was 4.2% (74/1 763) in lower-risk group, 6.6% (27/411) in intermediate risk group, and 8.2% (13/159) in higher risk group(P=0.02).Incidence of any revascularization was similar among groups(P=0.59). (4) The multivariable Cox analysis showed that age (HR=1.04, 95%CI 1.02-1.06, P<0.01), total implanted stent length (HR=1.01, 95%CI 1.00-1.02, P=0.03), and baseline SYNTAX score (HR=1.02, 95%CI 1.02-1.04, P=0.02) were independent risk factors of TLF after PCI in this patient cohort. Conclusion: The SYNTAX score is a valuable tool for predicting prognosis on 1 year in coronary heart disease patients underwent PCI. Trial Registration www.clinicaltrials.gov, NCT02017275.

[Basic characteristics and survival analysis of patients with hepatocellular carcinoma].

Objective: To analyze the basic characteristics of patients with hepatocellular carcinoma (HCC), and further explore the major factors affecting the prognosis of HCC patients. Methods: A total of 800 HCC patients were randomly selected from the Cancer Hospital, Chinese Academy of Medical Sciences. Their clinical and follow-up information was obtained from medical record. Univariate analysis of variance, Kaplan-Meier method and Cox regression analysis were used to analyze the patients' age at diagnosis and survival time, etc. Results: The average age of diagnosis was 55.04 years among all the 800 HCC patients, and the sex ratio of male to female was 4.48. The infection rates of HBV and HCV were 78.6% (629/800) and 5.8% (46/800), respectively. The smoking rate was 41.0% (328/800) and the alcohol consumption rate was 38.5% (328/800). 259 (32.4%) patients underwent radical treatments with liver resection as major therapy, and 541 (67.6%) patients adopted non-radical treatments with transcatheter arterial chemoembolization (TACE) as major therapy. The 1-, 3- and 5-year survival rates of the HCC patients were 73.2%, 53.7% and 42.4%, respectively. The risk factors for prognosis included alcohol abuse and treatment methods. The HR of alcohol abuse was 1.326 (95%CI: 1.058 to 1.661) and HR of treatment methods was 3.301 (95% CI: 2.483 to 4.387). Conclusions: Men account for the majority of HCC patients, and most patients have a lower age at diagnosis and adopt non-radical treatments. The exposure rates of HBV infection and alcohol abuse of HCC patients are significantly higher than those of general population. The major risk factors affecting prognosis and survival are treatments and alcohol abuse. Alcohol abuse and HBV may have synergistic effects on the survival of HCC patients.

[Analysis of psychological status and relevant factors of patients with esophageal and gastric cardia precancerous lesions in Linzhou of Henan].

Objective: To explore the psychological status and related factors in patients with precancerous of esophageal and gastric cardia in Linzhou of Henan. Methods: Clinical psycho-rating scale of Social Support Rating Scale (SSRS), Self-Rating Anxiety Scale (SAS, score ≥50 points with symptoms of anxiety) and Self-Rating Depression Scale (SDS, score ≥53 points with the symptoms of depression) were applied to survey life events and psychological status of subjects who aged 40-69 years old and participated in"The Early diagnosis and Early Treatment"program in Linzhou cancer hospital from July 2015 to Jan 2016. Patients with lower intraepithelial neoplasia or high-grade intraepithelial neoplasia were selected as precancerous lesions (n=118), and patients with normal grade were selected as healthy controls (n=210). Compare the differences of the scores between the two groups, and the logistic regression model was used to analyze the related factors of precancerous lesions and psychological status of the study subjects. Results: Precancerous lesions included esophageal (72 cases), gastric cardia (40 cases), esophageal and cardia dual source (6 cases); Precancerous lesions and healthy controls aged (57.17±7.71) and (53.12±7.99) years old, the difference was statistically significant (P<0.001). The anxiety and depression scale showed that the scores of SAS and SDS scores in the precancerous lesions were (37.18±10.01), (40.44±8.37) points, and (34.02±6.63), (38.49±8.73) points in control group, the difference was statistically significant (P=0.002, 0.032). While the social support total score (38.26±5.26), and subjective support score (24.08±3.83) and objective support score (7.50±1.89) in control group were all higher than those of precancerous group (36.80±6.18, 23.01±3.93, 6.93±1.57), and the difference were statistically significant (P=0.024, 0.016, 0.004). In addition, the Logistic analysis showed that subjects with low objective social support, subjective social support and anxiety symptoms were more likely to develop precancerous lesions, and the OR were 0.81, 0.72 and 1.05, respectively (P=0.028, 0.005, 0.009). Conclusion: Social support, anxiety and depression status may be related to the occurrence and development of esophageal and gastric cardia precancerous lesions.

[Long term safety and efficacy of a novel abluminal groove-filled biodegradable polymer sirolimus-eluting stent for the treatment of coronary de novo lesions].

Objective: To compare the long term safety and efficacy of the novel abluminal groove-filled biodegradable polymer sirolimus-eluting stent(Firehawk stent) and permanent polymer coating everolimus eluting stent(Xience V stent) for the treatment of coronary de novo lesions. Methods: This prospective, multi-center, non-inferiority, randomized control trial(TARGETⅠ trial) was performed between August 2010 and April 2011, a total of 460 patients with primary, de novo, single vessel and single coronary lesion from 16 medical centers were enrolled. The diameter stenosis of target lesion was ≥70%, and lesion length was≤24 mm. The patients were randomly assigned to treatment with Firehawk stent (Firehawk stent group) or Xience V stent (Xience V stent group) groups by a web-based allocation system and was stratified by center. The late lumen loss after 9 months, target lesion failure (TLF) which was a composite of cardiac death, target vessel myocardial infarction, or ischemia driven target lesion revascularization, patient-oriented composite endpoint (PoCE) which was a composite of all cause death, all cause myocardial infarction, or any revascularization, and stent thrombosis after 5 years were compared between the two groups. Results: (1) There were 2 patients without stent implantation dropped out of this trial. There were 227 patients in Firehawk stent group, and 231 patients in Xience V stent group. The baseline characteristics were similar between the two groups(all P>0.05). (2) The 9 months late lumen loss in Firehawk stent group was non-inferior to that in Xience V stent group ((0.13±0.24)mm vs. (0.13±0.18)mm, P=0.94). (3) A total of 442 (96.5%) patients completed 5 years clinical follow-up. There were no significant differences on 5-year TLF rate (6.0%(13/217) vs. 6.7% (15/225), P=0.77) and PoCE rate (12.0%(26/217) vs. 17.8% (40/225), P=0.09) between the Firehawk stent group and Xience V stent group. (4) Kaplan-Meier analysis showed that TLF rates between 1-5 years were similar in Firehawk stent group and Xience V stent group (5.7% and 6.6% respectively, HR=0.88, 95%CI 0.42-1.84, P=0.72). Land-Mark analysis showed that TLF rates bewteen 1-5 years were similar in Firehawk stent group and Xience V stent group (3.6% and 4.4% respectively, HR=0.83, 95%CI 0.34-2.00, P=0.67). Kaplan-Meier analysis showed that PoCE rates between 1-5 years were also similar in Firehawk stent group and Xience V stent group (11.4% and 17.3% respectively, HR=0.64, 95%CI 0.39-1.04, P=0.07). Land-Mark analysis showed that PoCE rates after 5 years were similar in Firehawk stent group and Xience V stent group (8.4% and 10.0% respectively, HR=0.66, 95%CI 0.40-1.10, P=0.11). (5) No stent thrombosis was documented in Firehawk stent group during the 5 years follow-up period, and there was 1 case of stent thrombosis in Xience V stent group after 3 years of stent implantation. Conclusion: TARGETⅠ trial results of 5 years follow up indicate the novel Firehawk stent have a durable safety and efficacy profile which is comparable to the Xience V stent in treating patients with single de novo coronary lesion.
