Objective To evaluate the predictive value of neutrophil-to-lymphocyte ratio (NLR) and hemoglobinto-white blood cell ratio (HWR) prior to treatment in prognosis of non-operative esophageal squamous cell carcinoma (ESCC) patients.Methods From October 2009 to November 2014,a total of 362 non-operative ESCC patients were enrolled in this prospective study.x2 test was used to analyze the relationship between NLR,HWR and general clinical features;Univariate and multivariate Cox regression analysis was performed to evaluate the association between variables and prognosis of non-operative ESCC patients.Results The optimal cutoff level of 1.23 for NLR and 24.92 for HWR were identified by X-title software.x2 test indicated NLR was significantly associated with gender,tumor length,T stage,TNM stage and fasting blood glucose level.Moreover,univariate and multivariate analyses showed that high NLR and high HWR were all associated with a poor prognosis in non-operative ESCC.However,when patients were specifically stratified by treatment modus,subset analysis showed that NLR was only predictive of prognosis in the concurrent chemoradiotherapy group (HR =4.080,95％ CI:1.074-15.497,P =0.039),whereas the influence of HWR on prognosis was just existed in the sequential chemoradiotherapy group (HR =2.625,95％ CI:1.311-5.254,P =0.006).Conclusions In this investigation,we found that high NLR and high HWR were associated with poor prognosis in non-operative ESCC.

ObjectiveTo investigate the independent risk factors of 30-day mortality of nontraumatic acute chest pain in emergency department so as to get non - traumatic acute chest pain risk score,MethodsThe clinical data of 532 patients with non - traumatic acute chest pain were reviewed.The independent risk factors of 30 - day mortality were identified after analysis of medical history,symptom and sign,laboratory findings by uuivariate analysis and logistic regression.Non- traumatic acute chest pain risk score was made as per the odds ratios of these risk factors. ResultsThe average age of the patients was (55.7 + 12.7 ) years,and 45 patients ( 8.4％ ) died after 30 days.In patients with non - traumatic acute chest pain,history of hypertension (OR:4.28; 95％ CI:1.59-11.55 ),prolonged chest pain (OR:1.1; 95％ CI:1.05-1.15),dyspnea (OR:6.61; 95％CI:2.40-18.10) and tachycardia (OR:1.02; 95％CI:1.00-1.04),high leucocyte count (OR:1.18; 95％CI:1.06-1.31) and D - Dimer ( OR:1.002; 95％ CI:1.001-1.002 ) predicted 30 - day mortality independently,whereas chest pain relieved by medicine (OR:0. 15; 95％ CI:0.04-0.65),high blood oxygen saturation (SaO2) (OR:0.89; 95％CI:0.83-0.98) and normal hematocrit (OR:0.92; 95％CI:0.86-0.99) were good markers to predict optimistic prognosis.Non - traumatic acute chest pain risk score was higher in 30 - day dead group than those in survival group significantly ( P ＜ 0.01 ),and mortality was significantly different between groups with various risk stratification (P ＜ 0. 01 ).Conclusions Clinical physician can predict 30 - day mortality and evaluate prognosis in patients with acute chest pain by using non - traumatic acute chest pain risk score quickly and effectively.

Objective To compare the in-hospital and follow-up clinical results of percutaneous coronary intervention(PCI)and coronary artery bypass grafting(CABG)in patients of left ventricular dysfunction with coronary artery disease.Methods 147 patients with left ventricular dysfunction were divided into PCI group(n=60)and CABG group(n=87).Clinical,angiographic and revascularization data were collected for analysis.Patients were by SPSS 13.0 software.P value of less than 0.05 was considered statistically significant.Results In-hospital MACCE rates and mortality ofthe two groups were comparable[(6.7%vs 9.2%,P＞0.05)and(1.7%vs 8.0%,P＞0.05)].Multivariate Logistic regression analysis indicated that in-hospital MACCE risk of the two groups were similar(OR≥3.03,95%CI 0.27～34.48,P＞0.05).22-month follow-up showed no signficance in MACCE rates (16.0%vs 13.8%,P＞0.05)and in repeated revaseularization rates(8.O%vs 1.7%,P＞0.05)between the two groups.Multivariate Cox regression analysis indicated that follow-up MACCE risk of the two groups were comparable (HR≥1.35,95%C/0.44～4.13,P＞0.05).Conclusion In coronary artery disease patients with left ventricular dysfunction,PCI and CABG have similar in-hospital and long-tem MACCE rates.Long-terra effect of PCI would be further increased with the wide use of drug-eluting stents.

Rabies is a highly fatal zoonotic disease that is widely prevalent worldwide. Through large-scale immunization measures and other control strategies, rabies has been gradually brought under control. The World Health Organization (WHO) has called for the elimination of canine-mediated human rabies by 2030. Detection of the rabies virus is not only crucial for diagnosing cases but also an essential tool for measuring progress in rabies elimination. This article provides an overview and review of research on rabies virus detection, covering antigen detection techniques, antibody detection techniques, nucleic acid detection techniques, and other detection method.

Objective To investigate the correlation between red blood cell distribution width(RDW) and in-stent restenosis(ISR)in patients with coronary heart disease after PCI.Methods A total of nine hundred and seventy-eight patients with coronary heart disease treated in Beijing Anzhen Hospital,Capital Medical University with DES stent implantation from March 2015 to March 2016 were enrolled in the study.Among them,493 patients(50.41%)underwent coronary angiography in the hospital at 6-12 months after the operation.According to the results of the angiography,the patients were divided into two groups: the ISR group and the non-ISR group.The basic data of the patients,the laboratory indexes and the coronary interventional procedures record were collected to analyze the factors that could lead to in-stent restenosis.Results 51 cases(10.34%)in the ISR group and 442 cases(89.66%)in the non-ISR group.The baseline characteristics of the two groups were similar,and there was no significant difference in gender,age, body mass index,combined with hypertension,family history of coronary heart disease,long-term administration of statin and follow-up interval(P>0.05).The proportion of patients with diabetes was significantly higher than that of the non-ISR group(37.3% vs.22.6%,P=0.021);the smoking rate was significantly higher in the ISR group(52.9% vs.35.7%,P=0.016).In terms of laboratory examination,there were no significant differences between the two groups in blood lipid levels and WBC,RBC,Hb and PLT counts between the two groups(P>0.05).The levels of serum RDW(13.4(13.00,13.80)vs.12.7(12.40,13.10),P<0.01)and hs-CRP (3.15(2.32,4.63)vs.1.33(0.63,3.16),P<0.01)were significantly increased in the patients with ISR.The stent length was longer in the ISR group((21.87 ± 5.20)mm vs.(19.14 ± 4.87)mm,P<0.01),the stent diameter was smaller((2.87±0.38)mm vs.(3.09±0.36)mm,P<0.01),the number of cases with serial stents in ISR group was higher than that in non-ISR group(45.1 % Vs 30.8%,P=0.038).Multivariate logistic regression analysis showed that RDW(OR=2.396,95%CI 1.655-3.471;P<0.01),hs-CRP(OR=1.052, 95%CI:1.001-1.105;P=0.044),DM(OR=2.029,95%CI:1.004-4.100;P=0.049),smoking(OR=2.252,95%CI:1.060-4.783;P=0.035),stent length(OR=1.149,95%CI:1.072-1.230;P<0.01),stent diameter(OR=0.210,95%CI:0.079-0.558;P=0.002)and serial stents(OR=2.306,95%CI:1.162-4.575;P=0.017)were independent risk factors for in-stent restenosis.Conclusion Red blood cell distribution width is an independent predictor of in-stent restenosis after PCI in patients with coronary heart disease.Chronic inflammation and oxidative stress may be the most important pathogenesis of ISR.

OBJECTIVE To calculate the cost of centralized dispensing of four categories of drugs （ordinary drugs， antibacterial drugs， hazardous drugs， and parenteral nutrition solutions） in pharmacy intravenous admixture service （PIVAS）， and provide reference for setting charging standards for relevant departments. METHODS The operating costs of PIVAS in 12 medical institutions from Shaanxi province were collected through questionnaire survey， including labor costs， medical and health material costs， fixed asset depreciation and repair costs， water and electricity costs， and management costs. The operation time allocation coefficient method and workload allocation coefficient method were comprehensively used to allocate the above costs， and the unit preparation costs of four categories of drugs were calculated. RESULTS The average annual total costs of dispensing ordinary drugs， antibacterial drugs， hazardous drugs， and parenteral nutrition solutions in Shaanxi province were （2 195 900.25±1 680 893.73） yuan， （746 341.59±725 839.39） yuan， （331 420.15±183 258.83） yuan， and （330 322.68±277 281.70） yuan， respectively， with labor costs accounting for the highest proportion， averaging 85.49%. The costs of dispensing a set of ordinary drugs， antibacterial drugs， and hazardous drugs were 5.89， 7.60， and 14.37 yuan， respectively； the cost of dispensing one bag of parenteral nutrition solution was 32.15 yuan （excluding the cost of disposable intravenous nutrition bags）. CONCLUSIONS The cost calculation method and data of different types of intravenous drugs obtained in this study can provide reference for relevant departments to formulate and adjust PIVAS fee standards.
