RESUMO
Objective: To investigate the relationship between the long-non-coding RNA LINC00342 expression and the clinicopathological parameters of head and neck squamous cell carcinoma (HNSCC) and the biological function of LINC00342 in HNSCC cells. Methods: The expression level of LINC00342 in the HNSCC was analyzed using transcriptome sequencing data from TCGA (The Cancer Genome Atlas) database, and the expressions of LINC00342 in laryngeal squamous cell carcinoma tissues (LSCC) of 27 patients in the First Hospital of Shanxi Medical University were detected by transcriptome sequencing. The expression levels of LINC00342 in human embryonic lung diploid cells 2BS, HNSCC cell lines FD-LSC-1, CAL-27 and Detroit562 were determined by real-time quantitative polymerase chain reaction (qPCR). RNAi (RNA interference) was used for LINC00342 knockdown in HNSCC cell lines, and the changes of malignant phenotype in the tumor cells after LINC00342 knockdown were examined by cell counting kit-8 (CCK-8), colony formation, flow cytometry, transwell invasion and migration assays. Bioinformatics analysis was performed to construct a LINC00342-centered competing endogenous RNA (ceRNA) regulatory network, and GO (Gene Ontology) enrichment analysis was performed. Statistical analysis and graphing were performed using SPSS 25.0 software and GraphPad Prism 6 software. Results: Mean LINC00342 levels in HNSCC tissues and TCGA database were higher than that in normal control tissues, but with no significantly statistical difference (P=0.522). LINC00342 expression levels were positively correlated with cervical lymph node metastasis and pathological grade in patients with HNSCC, with higher expression in male patients than in female patients (P<0.05). Transcriptome sequencing analysis showed that mean expression level of LINC00342 in LSCC tissues of 27 patients was significantly higher than that in the paired adjacent normal mucosa tissues (t=1.56, P=0.036). LINC00342 expression was significantly upregulated in HNSCC cell lines FD-LSC-1, CAL-27 and Detroit562 (t-values of -12.17, -23.26 and -388.57, respectively; all P<0.001). Knockdown of LINC00342 by transfecting si-LINC00342-1 and si-LINC00342-2 inhibited HNSCC cell proliferation (t-values of 8.95 and 4.84, 2.70 and 5.55, 2.02 and 3.70, respectively), colony formation (t-values of 6.66 and 6.17, 7.38 and 11.65, 4.90 and 5.79, respectively), migration (t-values of 8.21 and 7.19, 5.76 and 6.46, 6.28 and 9.92, respectively) and invasion abilities (t-values of 9.29 and 10.25, 11.30 and 11.36, 8.02 and 8.66, respectively), but promoting apoptosis in cell lines FD-LSC-1 and CAL-27 (t-values of -2.21 and -5.83, -3.05 and -5.25 respectively) (all P-values<0.05). The LINC00342-centered ceRNA network consists of 10 downregulated microRNA and 647 upregulated mRNA nodes. GO analysis results indicated that LINC00342-regulated mRNAs were enriched in 22 biological processes, 32 molecular functions, and 12 cellular components. Conclusion: High level of LINC00342 is associated with the malignant progression of HNSCC. LINC00342 promotes the proliferation, migration, invasion, and antagonizes apoptosis of HNSCC cells, which serves as a potential molecular marker in HNSCC.

The purpose of this study was to isolate and screen LAB that are well suited to the intestinal characteristics of the Chinese population, with excellent probiotics and high antibacterial activity. After 16S ribosomal RNA (rRNA) homology and phylogenetic tree analysis, potential probiotics were tested for their antibacterial activity, resistance to artificial gastrointestinal fluid and drugs, surface hydrophobicity, and safety. Three strains of LAB with acid resistance, bile salt resistance, epithelial cell adhesion, and no multidrug resistance were selected:
RESUMO
Objective:To develop a simple and accurate method for molecular authentication of Panax ginseng and P. quinquefolius.Method:The mitochondrial cox Ⅱ sequences of P. ginseng and P. quinquefolius were amplified by polymerase chain reaction(PCR)with universal primers. PCR products of the two species were sequenced in both directions, and sequence alignments were conducted for intron length polymorphisms exploitation. Multiplex PCR was established for the identification of P. ginseng and P. quinquefolius with their specific primers,which were designed respectively based on their insertion sequences. And the limit of detection of the multiplex PCR was also determined.Result:The insertion/deletion sequences were exploited in mitochondrial cox Ⅱ. Under the established multiplex PCR assay,P. ginseng generated a 729 bp specific band, while P. quinquefolius yielded a 141 bp specific amplicon,and the mixture of the two species yielded both 729 bp and 141 bp fragments. The established multiplex PCR assay could detect 0.1% of intentional adulteration of P. quinquefolius into P. ginseng, with down to 0.001 ng of genomic DNA.Conclusion:The established multiplex PCR assay can accurately identify P. ginseng and P. quinquefolius from different sources, without the optimization of reaction system and the introduction of additional mismatches,so as to provide a new molecular marker method for identifying botanical origin of P. ginseng and P. quinquefolius.
RESUMO
Traditional Chinese Medicine (TCM) is one of the oldest systems of medicine. More and more attention has been paid to TCM application, but the variable quality of clinical trials with TCM impedes its widespread acceptance. The Standard Protocol Items: Recommendations for Interventional Trials (SPIRIT) 2013 Statement has established guidelines for designing clinical trials to ensure that the trial results are accurate and reliable. However, there are difficulties when applying SPIRIT 2013 Statement to trials with TCM, due to the unique theory and the characteristic of TCM intervention. An Extension to the original SPIRIT was developed to ensure the quality of trial design with TCM. As Chinese herbal formulae, acupuncture and moxibustion are common and representative interventions in TCM practice, the executive working group determined that the SPIRIT-TCM Extension focus on these three interventions. Extension was developed through initiation, 3 rounds of Delphi consensus survey, and finalizing expert meeting. Seven items from the SPIRIT 2013 Statement were modified, namely, "title", "background and rationale", "objectives", "eligibility criteria", "interventions", "outcomes", and "data collection methods". The Extension includes the introduction of the concept of TCM pattern and 3 major TCM interventions, with examples and explanations. The SPIRIT-TCM Extension 2018 provides suggestion for investigators in designing high quality TCM clinical trials. It is expected that wide dissemination and application of this extension ensure continuous improvement of TCM trial quality throughout the world.

Objective To explore the association between frailty and muscle performances of hospitalized elder adults with coronary artery disease.Methods A total of 122 hospitalized patients aged 65-85 years old with coronary artery disease from Department of Geriatrics and Cardiology,Peking Union Medical College Hospital between December 2017 and March 2018 were enrolled in the study.A comprehensive geriatric assessment was performed to evaluate existing comorbidity and geriatric syndromes of the patients.Frailty was assessed using the Clinical Fraity Scale.The patients were classified as frail and non-frail,according to the scale.Muscle performances were assessed using grip strength,gait speed,etc.Whole body and appendicular skeletal muscle mass was detected with bioelectrical impedance analysis in patients with reduced grip strength or slowed gait speed.Appendicular skeletal muscle index (ASMI) was calculated.Results Among all subjects,28 were with frailty (23.0%) and 94 were without (77.0%).The frail patients were older [(76.7±5.4) years vs.(72.2±5.6)years],had higher Charlson comorbidity index [2.0(1.0,2.75)vs.1.0(0,2.0)],and higher proportion of malnutrition (14.29% vs.1.06%),urinary incontinence (39.29% vs.15.96%),using walking-aid (28.57% vs.6.38%),and more kinds of taken drugs (8.1±3.0 vs.6.6±2.7),than the non-frail patients.Prealbumin levels [(207.8±60.0)mg/L vs.(234.3±45.4)mg/L] were lower,and highly sensitive C-reactive protein levels [(5.89±9.57)mg/L vs.(1.89±2.49)mg/L] were higher in the frail patients than in the non-frail patients (all P<0.05).Compared with non-frail patients,the frail patients had poorer grip strength [(19.67±7)kg vs.(29.23±8.29)kg] and slower gait speed [(0.54±0.2)m/s vs.(0.91±0.22)m/s](all P<0.001).Spearman rank correlation analyses showed that grip strength was positively correlated with the appendicular skeletal muscle mass(r =0.811),whole body skeletal muscle mass(r =0.74) and the ASMI (r =0.783),respectively.Conclusions The incidence of frailty among hospitalized older adults with coronary artery disease is high.Poor muscle performances were common in these patients.Assessment of frailty and muscle performances can help to evaluate the overall function of older adults with cardiovascular disease in a comprehensive way.
RESUMO
Objective To modify the rat model of diarrhea-predominant irritable bowel syndrome(IBS-D) induced by chronic restrain stress,and to evaluate the modified model. Methods Thirty specific-pathogen free Sprague Dawley rats were randomly divided into control group,one-hour model group and 2-hour model group, 10 rats in each group and half being male. One-hour model group and 2-hour model group were given restrain stress one, 2 hour (s)per day respectively, and the treatment lasted 14 days. On day 7, 14, 21, 28 after modeling,the number of feces grains within 4 hours,area of the excrement and body mass were monitored. On modeling day 28 , abdominal withdrawal reflex (AWR) scores for visceral sensitivity were calculated , the pathological features of gastric antrum, duodenal, ileac, colonic tissues were observed by hematoxylin-eosin staining, and the expression level of 5-hydroxytryptamine-3A receptor (5-HT3AR) in rat colon tissue was detected by real time quantitative polymerase chain reaction(qPCR). Results Compared with control group,the number of feces grains in one-hour model group showed no obvious changes on day 7, 14, 21, 28, but the area of the excrement was obviously increased and body mass was decreased on day 14 (P < 0.05 or P < 0.01);in 2-hour model group,the number of feces grains and area of the excrement were increased on day 21,28, and body mass was decreased obviously on day 7,14,21,28 (P < 0.05 or P < 0.01). One-hour model group and 2-hour model group had higher AWR scores than the control group (P < 0.05),but the difference between the two model groups was insignificant(P > 0.05). The optical microscopy results showed that no various changes in gastric, duodenal, ileac, colonic tissues in the two model groups as compared with those in the control group. QPCR results showed that the expression level of 5-HT3AR in rat colonic tissues of the two model groups was higher than that of the control group (P < 0.05), but the expression level of 5-HT3AR in rat colonic tissues of model was not significantly different from that of the control group(P > 0.05). Conclusion IBS-D model can be successfully established with chronic restrain stress for 2 hours per day and lasting for 14 days. Excrement area and AWR scores can be used as the objective indexes for the evaluation of IBS-D model.

Objective: To explore the changes of peripheral leukocyte’s telomere length (LTL) in patients of premature coronary artery disease (PCAD) with inlfuencing factors. Methods: Our research was conducted in 2 sets of groups, by coronary artery condition: PCAD group,n=128 including 88 patients with ACS, 40 with SCAD and Non-CAD group,n=128 subjects; by age status: the age≤30 years, 31-40 years, 41-50 years, 51-60 years had 2, 14, 65, 47 patients in each group respectively. Peripheral LTL was detected by lfuorescent quantitative analysis, the relationship between LTL and PCAD with inlfuencing factors were studied by Spearman correlation analysis. Results: In PCAD group, compared with SCAD patients, ACS patients had more male gender, higher Gensini score, lower T/S ratio and shorter LTL, allP<0.05. Compared with Non-CAD group, PCAD group had decreased T/S ratio (0.88 ± 0.86) vs (1.10 ± 0.57),P<0.05. T/S ratio was negatively related to age in both PCAD group (r=-0.275,P=0.002) and Non-CAD group (r=-0.316,P=0.000). Spearman correlation study presented that in PCAD group, LTL was negatively related to hyperlipidemia (r=-0.415,P=0.049) and diabetes (r=-0.472,P=0.036); multi linear regression analysis indicated that in PCAD group, LTL was negatively related to age (B=-0.023,P=0.038) and in Non-CAD group, LTL was negatively related to age (B=-0.027,P=0.000), smoking (B=-0.278,P=0.012), HDL-C (B=-0.297,P=0.046). Conclusion: PCAD had more male ACS patients with shorter LTL and severer coronary lesions; LTL was negatively related to hyperlipidemia and diabetes, age was an important inlfuencing factor for LTL shortening.
RESUMO
The safety of Chinese patent medicine has become a focus of social. It is necessary to carry out work on post-marketing clinical safety evaluation for Chinese patent medicine. However, there have no criterions to guide the related research, it is urgent to set up a model and method to guide the practice for related research. According to a series of clinical research, we put forward some views, which contained clear and definite the objective and content of clinical safety evaluation, the work flow should be determined, make a list of items for safety evaluation project, and put forward the three level classification of risk control. We set up a model of post-marketing clinical safety evaluation for Chinese patent medicine. Based this model, the list of items can be used for ranking medicine risks, and then take steps for different risks, aims to lower the app:ds:risksrisk level. At last, the medicine can be managed by five steps in sequence. The five steps are, collect risk signal, risk recognition, risk assessment, risk management, and aftereffect assessment. We hope to provide new ideas for the future research.

ObjectiveTo assess the efficacy and safety of Xuebijing injection for the treatment of severe acute pancreatitis (SAP).Methods An extensive search of related literatures from the Cochrane Library, EMBASE, China Biology Medicine (CBM), CNKI, VIP and Wanfang data up to March 2014 was performed. Randomized controlled trials (RCTs) regarding Xuebijing injection for the treatment of SAP were collected regardless of languages. Jadad scale was taken for quality evaluation of the included studies by two researchers. The patients in control group were given conventional treatment, and those of the Xuebijing group were given Xuebijing injection on the top of conventional treatment. The Cochrane Collaboration RevMan 5.2 software was used for data analysis regarding the effect of Xuebijing injection on the mortality, incidence of complication, effective rate, the length of stay in hospital, and the safety of the drug in patients with SAP.Results A total of 15 published reports meeting the inclusion criteria were enrolled. The methodological quality of the trials was low. Meta analysis showed that the mortality in Xuebijing group was significantly lower [odds ratio (OR) = 0.37, 95% confidence interval (95%CI) =0.17 - 0.77,P = 0.008], and the incidence of complication was also significantly decreased (OR = 0.26, 95%CI =0.14 - 0.45,P< 0.000 01) as compared with those of control group. The effective rate in Xuebijing group was significantly higher than that of the control group [relative risk (RR) = 0.85, 95%CI = 0.80-0.91,P< 0.000 01]. The length of stay in hospital in Xuebijing group was significantly shorter than that of the control group [mean difference (MD) = -5.28, 95%CI = -6.69 to -3.86,P< 0.000 01]. Adverse reactions of Xuebijing injection were reported in 2 studies. The adverse reaction in one study was headache and nausea, which were relieved by adjusting the speed of intravenous infusion, and mild rash was reported in another case, and it disappeared after the withdrawal of Xuebijing. Conclusions The currently available evidence shows that Xuebijing injection may have some therapeutic effect on SAP. Because of the low methodological quality of the included trials, multi-center and high-quality RCTs with large sample sizes are needed to provide stronger evidence.

Objective To investigate the clinical features of young female patients with acute myocardial infarction (AMI) who were referred to Peking Union Medical College Hospital. Methods A total of 24 consecutive AMI female patients (age≤44 years) who underwent coronary angiography were retrospectively retrieved from the database, and 70 AMI patients whose age ≥ 65 years and who also underwent coronary angiography were enrolled as a control (elderly) group. Clinical features were compared between the two groups. Results Of the 24 young female AMI patients, MI from non-atherosclerosis was identiifed in 9 patients (non-ATS group). Compared to the remaining 15 young female AMI patients (ATS-group), non-ATS group was younger (P<0.05), with lower BMI (P<0.05) and less traditional risk factors of coronary heart disease (P<0.05). Coronary angiography showed more normal artery (P<0.05) and lesions on left main (P<0.05). However, when compared to the elderly group, the young female ATS-group was associated with less hypertension (P<0.01), smoking (P<0.05), traditional risk factors (P<0.01) and lower level of blood pressure (P<0.05), fasting glucose (P<0.05), serum creatine (P<0.01), TC (P<0.05), and LDL-C (P<0.01) at admission. Coronary angiography showed single vessel disease was the most common lesion. Conclusions Acute myocardial infarction in young female might be caused by non-atherosclerosis. Those due to atherosclerosis differ in coronary risk factors and angiographic features from the elderly female AMI patients.
RESUMO
Antiplatelet therapy and stent implantation have been the dominant treatment to reduce the mortality of patients with coronary artery disease.Recently,studies have showed that adverse cardiac events still occur in part of patients with coronary artery disease after the antiplatelet treatment with aspirin and/or clopidogrel.Thus,resistance to aspirin and clopidogrel has attracted increasing attention.It will be great benefit to these patients who were identified resistance and made tailoring antiplatelet therapy So far many platelet function tests has been used in clinical to monitor the reaction of the antiplatelet drugs for prevention and treatment of thrombosis in patients with coronary artery disease.These monitoring tests may be chosen based on different antiplatelet drugs including aspirin,clopidogrel and GP Ⅱ b/Ⅲ a antagonist.The results of antiplatelet drug resistance may be different due to different platelet function methods,thus the related clinical adverse events needs further verification.
RESUMO
Objective The purpose of this study is to determine whether the TransAtlantic InterSociety Consensus (TASC) criteria (Ⅱ-2007 versions), the Society of Vascular Surgery (SVS) runoff score or risk factors for peripheral arterial disease were correlated with postoperative outcome of superficial femoral artery occlusive disease. Methods From January 2006 to September 2009, patients who suffered from lower extremity atherosclerosis occlusion disease and underwent endovascular or surgical therapy in superficial femoral artery segment were reviewed retrospectively at Beijing Tongren Hospital. Femoralpopliteal artery lesions were graded according to the TASC Ⅱ criteria. Runoff scores were determined in infrapopliteal artery segment lesions. All patients were followed up. Kaplan-Meier method was applied to calculate primary patency rate, and COX regression analysis was used to determine if TASC Ⅱ classification,runoff score, or factors for peripheral arterial disease affected primary patency rate. Results 142 patients (197 limbs) were followed up after treatment at 1 month, 3 months, 6 months, and every 6 months thereafter. Median follow-up time was 13 months. By Cox regression analysis, TASC Ⅱ classification(RR =1.471,P = 0. 012 ), runoff score ( RR = 1.190, P = 0. 004 ), and type 2 diabetic mellitus ( RR = 2. 320, P =0.019) significantly affected primary patency. Conclusions Postoperative poor patency rates are associated with higher degree of the TASC Ⅱ lesions, poor initial runoff score, and type 2 diabetic mellitus in patients of superfical femoral artery occlusive disease.
RESUMO
<p><b>OBJECTIVE</b>To compare clinical characteristics among premenopausal women with coronary arterial disease (CAD) with or without atherosclerosis (AS) and postmenopausal women with CAD.</p><p><b>METHODS</b>The clinical and coronary angiographic data, traditional risk factors (age, smoking, blood pressure, lipid profile, blood glucose, BMI, family history) were compared among premenopause (Pre-M, n=42) and post-menopause (Post-M, n=172) women with CAD as well as Pre-M patients with non-AS CAD (non-AS CAD, n=8).</p><p><b>RESULTS</b>Compared with the Post-M patients with CAD, Pre-M CAD patients had significantly fewer traditional risk factors, such as hypertension, diabetes and hypercholesterolemia, significantly more acute coronary syndrome and fewer previous history of chest pain, significantly more single vessel lesion and lower Gessini score (all P < 0. 01). The logistic regression results showed that obesity is an independent risk factor for the development of CAD in premenopausal women (OR = 3. 655, 95% CI: 1. 5-11.59, P = 0.028). Hypertension (OR = 4.73, 95% CI: 0.991-22.589, P = 0.051) and hypercholesterolemia (OR = 4.68, 95% CI: 0.971-22.564, P = 0.055) might also contribute to the development of CAD in these patients. Clinical characteristics were similar between Pre-M and non-AS CAD patients (P > 0.05).</p><p><b>CONCLUSIONS</b>Pre-M CAD patients had less traditional risk factors and lower coronary lesion score compared to post-M CAD patients. Obesity is an independent risk factor for Pre-M CAD. Non-AS coronary artery disease is also an important reason for the development of coronary arterial events in premenopausal women.</p>

Surgery and endovascular techniques are the most important methods in treating lower limb atherosclerosis occlusion.Different strategies should be adopted according to the features of lesion in lower limb.This article reviews the latest clinical outcomes in treating lower limb atheroselerosis occlusion with surgery and endovascular techniques.
RESUMO
<p><b>OBJECTIVE</b>To analyze clinical characteristics in young and aged patients with coronary artery disease (CAD).</p><p><b>METHODS</b>The clinical and coronary angiographic data were compared between young (PCAD, male < 55 years old, n = 74, female < 65 years old, n = 71) and aged (CAD, male > 55 years old, n = 106, female > 65 years old, n = 111) patients. Seventy-one patients excluded with CAD by angiography served as controls (non-CAD). The traditional risk factors (including age, smoking, blood pressure, lipid profile, blood glucose, BMI, family history), coronary angiographic changes were analyzed and compared among various groups.</p><p><b>RESULTS</b>(1) Compared with CAD group, PCAD patients had significantly higher rate of smoking (50.3% vs. 38.0%, P < 0.05), significantly higher positive CAD family history rate (29.7% vs. 19.9%, P < 0.05) and significantly higher TG level [(2.13 +/- 1.89) mmol/L vs. (1.78 +/- 1.14) mmol/L, P < 0.05], while had significantly fewer traditional risk factors (2.50 +/- 1.28 vs. 2.76 +/- 1.43, P < 0.05) and lower hypertension rate (59.3% vs. 73.3%, P < 0.05). There were significantly more PCAD patients with acute coronary syndrome (66.2% vs. 42.6%, P < 0.05), more PCAD patients had single vessel lesion (51.0% vs. 30.4%, P < 0.05), lower average lesion score (4.86 +/- 2.30 vs. 5.92 +/- 2.66, P < 0.05). (2) The logistic regression results showed that positive CAD family history (P = 0.029, OR = 1.766, 95% CI 1.060 - 2.940) and smoking (P = 0.066, OR = 1.561, 95% CI 0.971 - 2.510) are important independent risk factors for the development of PCAD.</p><p><b>CONCLUSIONS</b>Smoking, positive family history and the increased TG might contribute to the pathogenesis of PCAD.</p>
