Study on the Correlation between Intestinal Flora Imbalance and Cervical Spondylosis QIU Yuhang
The Second Clinical Medical College,Nanjing University of Chinese Medicine,Nanjing 210023,China
【Abstract】 Cervical spondylosis(CS) has been regarded as a degenerative disease of the spine caused by external strain.Most of the studies focus on its structural changes,but few on its immune mechanism.The intestinal flora(IF) has been shown to be widely involved in the immune regulation of various tissues of the human body,and it is also possible to influence the occurrence and development of CS through immunoinflammatory pathways.Through literature review and analysis of the influence of IF imbalance on bone,blood vessels,nerves and muscles,it was suggested that IF imbalance may act on the main tissues of the neck by the gut-brain axis as main stem,causing neck tissue lesions.The chronic low-level immune inflammation caused by IF imbalance,which is the fundamental basis for the formation of CS,can cause damage to the neck tissues of bones,blood vessels,nerves and muscles,while stress strain is only a supplementary factor and the degeneration of neck tissues is only a process or result in this disease.CS is not only a manifestation of the cervical spine aging and disuse,but also more should be regarded as a neck injury caused by intestinal immune disorders.In the clinical treatment of CS,it should pay attention to reasonable diet for protecting intestinal function and maintaining the existing attributes of IF.

【Abstract】 Background Polypharmacy burden is a core factor that affect patients' medication beliefs,medication compliance,and medication safety.By evaluating the patient's medication burden in time,healthcare workers may find out the problems that need to be solved in the process of medicine use,by which a scientific drug intervention plan may be formulated.However,at present,there is a lack of scientific and effective tools to evaluate the patient's polypharmacy burden in China.Objective To translate the English version of Living with Medicines Questionnaire(LMQ)into Chinese,and test its reliability and validity in community-living elderly patients with polypharmacy,to provide a tool for assessing the medication burden in this group.Methods The Chinese version of LMQ(initial version)including 8 dimensions and 39 items was formed by using forward translation,proofreading,back translation,expert review,cognitive interview and presurvey.From April to August 2019,convenience sampling was used to select elderly chronic disease patients with polypharmacy from communities served by three community health centers〔Zhengzhou Community Health Center(East 2nd Street),Linshanzhai Community Health Center,Science Avenue Community Health Center of Zhengzhou National High & New Industries Development Zone〕in Zhengzhou as the participants.In the first stage of this study,the data were collected for exploratory factor analysis,and the sample size was 260 cases.In the second stage,the reliability of the initial version of questionnaire was retested 2-4 weeks later in a sample of 30 cases randomly selected from the above-mentioned 260 cases.In the third stage,the data were collected for confirmatory factor analysis,with a sample of 373 cases.The investigation used the General Data Questionnaire and the Chinese version of LMQ(initial version).The validity and reliability of the final Chinese version of LMQ were evaluated overall.Results The questionnaire results of effective responders in the first,second,and third stages of this study〔242(93.1%),30(100.0%),and 350(93.8%)〕were included for final analysis.Item analysis showed that the item-total correlation coefficients of the Chinese version of LMQ(initial version)were 0.317-0.658(P<0.01),and the critical value for each item was > 3.0.The results of exploratory factor analysis showed that the KMO value of Chinese version of LMQ(initial version)was 0.875,and the χ2 of Bartlett's test was 8 139.877(P<0.01),which indicated that it was suitable for factor analysis.Eight common factors with eigenvalue > 1.000 were extracted,explaining 76.780% of the total variance,and the loading value of each item on its common factor was > 0.400.The results of confirmatory factor analysis showed that the pre-set model fitting indicators were not ideal,so the model was modified according to the indicator prompts.After adding 8 covariance correlations,the fitting indicators are in the acceptable range.Content validity:the item content validity indices of the Chinese version of LMQ(initial version)were 0.86-1.00,and the scale content validity index was 0.949.Reliability:the scale Cronbach's α coefficient was 0.892,with dimensions' Cronbach's α coefficients ranging from 0.867-0.943; the scale half-reliability was 0.817 with dimensions' half-reliability ranging from 0.841-0.947; the scale retest reliability was 0.904 with dimensions' retest reliability ranging from 0.802-0.875.The final Chinese version of LMQ includes 8 dimensions(39 items):medication attitude(7 items),practical difficulties(6 items),doctor-patient relationship(5 items),medication effects(5 items),interferences with daily life(6 items),side effects(4 items),medication behavior(3 items),economic burden(3 items).Conclusion The Chinese version of LMQ uses simple and easy-to-understand 39 items to assess the patient's medication burden from 8 aspects(medication attitude,practical difficulties,doctor-patient relationship,medication effects,interferences with daily life,side effects,medication behavior,and economic burden),demonstrating good validity and reliability.The assessment is comprehensive and easy to implement,which may effectively assess the burden of medication in community-living elderly patients with polypharmacy,and may provide a measurement tool for healthcare workers to formulate precise drug interventions.

【Abstract】 Background Elevated levels of acute glycemia at hospital admission are common among patients with acute myocardial infarction(AMI).It has been found that in clinical practice,AMI patients are often combined with a variety of complex clinical factors,which may cause acute hyperglycemia.Acute-to-chronic glycemic ratio may be a predictor of poor short-term prognosis in such patients,but relevant studies are still lacking in China.Objective To study the relationship between acute-to-chronic glycemic ratio and poor short-term prognosis in patients with AMI.Methods We enrolled 272 inpatients with ST-elevation and non-ST-elevation AMI from CCU,Guizhou Provincial People's Hospital between January 2017 and January 2018.The primary end point of the study was mortality within a 30-day follow-up.Venous plasma glycemia and glycosylated hemoglobin(HbA1c) levels were measured at hospital admission,then the chronic glycemia was estimated based on HbA1c,and acute-to-chronic glycemic ratio was calculated further.Factors associated with poor short-term prognosis were analyzed.The ROC curve of acute-to-chronic glycemic ratio in predicting poor short-term prognosis of AMI was plotted,and the optimal cutoff value was estimated.Kaplan-Meier method was used for survival analysis.The incidence of adverse cardiovascular events was explored by acute-to-chronic glycemic ratio.Results By the survival status,the patients were divided into the survival group(n=256) and the death group (n=16).Multivariate Logistic regression analysis showed that Killip classⅡ-Ⅲ,three-vessel coronary artery lesions and elevated acute-to-chronic glycemic ratio were independent risk factors associated with poor short-term prognosis(OR=23.110,0.073,35.885,P<0.05).Patients were divided into acute-to-chronic glycemic ratio >1.01 group(n=138) and≤1.01 group(n=134)by the cutoff value,and the former group had much lower short-term cumulative survival rate(90.3% vs 97.8%)(χ2=6.932,P=0.008)showed by survival analysis.Further subgroup analysis by diabetes indicated that,those without diabetes and acute-to-chronic glycemic ratio >1.01 had a significantly reduced short-term cumulative survival rate compared with those with diabetes and acute-to-chronic glycemic ratio≤1.01(92.3% vs 97.5%)(χ2=4.465,P=0.035)those with diabetes and acute-to-chronic glycemic ratio >1.01 had a significantly reduced short-term cumulative survival rate compared with those with diabetes and acute-to-chronic glycemic ratio≤1.01(86.0% vs 100.0%)(χ2=5.658,P=0.017).Acute pulmonary edema,cardiogenic shock,atrial tachycardia,and ventricular tachycardia were significantly increased in acute-to-chronic glycemic ratio >1.01 group (P<0.05).Conclusion  Elevated acute-to-chronic glycemic ratio is an independent risk factor for poor short-term prognosis in patients with AMI,and is closely related to adverse cardiovascular events.Elevated acute-to-chronic glycemic ratio is also associated with lower short-term cumulative survival rate and poorer short-term prognosis in AMI patients with or without diabetes.Its value is more valuable to predict the poor short-term prognosis in those with diabetes.Acute-to-chronic glycemic ratio >1.01 may be used as the optimal cutoff value to predict the poor short-term prognosis of patients with AMI.Above this level,cardiovascular adverse events may increase significantly and the short-term prognosis of patients may be poor.

【Abstract】 Background Diabetic retinopathy(DR) is a common microvascular complication of diabetes.At present,ophthalmoscopy is the major screening method of DR.By contrast,serum Cystatin C(Cys-C),a more sensitive and accurate screening method as it is not affected by physiological factors such as age,race or muscle weight,is becoming popular in the studies of microangiopathy.However,there has been not any publications about the studies on the diameter of microvessels between serum Cys-C and type 2 diabetes mellitus(T2DM).Objective To study the effect of serum Cys-C level on retinal artery equivalent(RAE),retinal vein equivalent (RVE) and artery-to-vein ratio(AVR) in patients with T2DM.Methods The study retrospectively analyzed the clinical baseline data and color fundus photographs of 110 patients screened for T2DM in Nanfang Hospital,Southern Medical University from July 2014 to July 2018.The retinal vessel diameter in the superior temporal 1.0-1.5 PD range of left eye was measured by ImageJ software.The effect of serum Cys-C level on RAE,RVE and AVR,the correlation between serum Cys-C level and clinical baseline data,the influencing factors of serum Cys-C level abnormality and the influence of serum Cys-C level on RAE,RVE and AVR were analyzed.Results The level of serum Cys-C was positively correlated with the course of diabetes,creatinine(Cr),uric acid(UA) and blood urea nitrogen(BUN)(rs=0.193,0.821,0.501,0.678,P<0.05).The level of serum Cys-C was negatively correlated with total CO2 and estimated glomerular filtration rate(eGFR)(rs=-0.281,-0.745,P<0.05).The level of serum Cys-C in T2DM patients with hypertension,diabetic nephropathy,and DR was significantly higher than that in patients without those diseases (P < 0.05).The levels of serum Cys-C in T2DM patients with non-diabetic retinopathy (NDR),nonproliferative diabetic retinopathy (NPDR),and proliferative diabetic retinopathy (PDR) were (1.07±0.23),(1.31±0.64),and (2.12±1.73) mg/L,respectively,which presented a statistically significant difference(F=7.245,P=0.002).Binary Logistic analysis showed that uric acid and eGFR were risk factors for abnormal serum Cys-C(P<0.05).The level of RVE was positively correlated with the level of serum Cys-C(rs
=0.236,P<0.05);AVR was negatively correlated with the level of Cr and serum Cys-C(rs=-0.190,-0.299;P<0.05).The results of ordered multi-classification Logistic regression analysis showed that smoking,drinking,coronary heart disease,and abnormal serum Cys-C level were the risk factors for the increase of RVE(P<0.05).The area under the ROC curve for predicting AVR anomalied by serum Cys-C was 0.615〔95%CI(0.508,0.721)〕,while the best critical value for serum Cys-C to predict AVR anomalies was 1.105 mg/L,the Jordan index was 0.26,the sensitivity was 0.673 and the specificity was 0.582.Conclusion The level of serum Cys-C is affected by UA and eGFR.The increase of serum Cys-C level leads to an aggregation of DR,an enlargement of RVE and a diminution of AVR.Therefore,RVE level is positively correlated with serum Cys-C level,AVR level is negatively correlated with serum Cys-C level,but there is no correlation between RAE and serum Cys-C level.When serum Cys-C≥1.105 mg/L,the AVR is predicted to be less than 2/3.

【Abstract】 Background Gastroesophageal reflux disease(GERD) is a common digestive system disease with high prevalence,complex and diverse clinical symptoms.Moreover,it shows an increasing trend in annual prevalence.Besides those who are diagnosed with GERD by the chief complaint of typical reflux symptoms,more and more patients are diagnosed by atypical symptoms.To provide guidance for clinical diagnosis and treatment,the differences between GERD patients with typical and atypical symptoms are needed to be further studied.Objective To compare the differences in reflux characteristics and esophageal motility between GERD patients with typical and atypical symptoms,to fully explore the characteristics of GERD with atypical presentations to improve the understanding of this disease.Methods We retrospectively enrolled GERD outpatients with typical and atypical presentations from Department of GI Medicine,Affiliated Hospital of Zunyi Medical University during from January 2015 to January 2017.All of them had pathological reflux detected by 24-h multichannel intraluminal impedance-pH monitoring(MII-pH),and had no other organic gastrointestinal disorders determined by high-resolution manometry(HRM) and gastroscopy.According to the main symptoms,the patients were divided into typical presentations group and atypical presentations group.We compared these two groups' baseline data,reflux characteristics〔number of reflux episodes(pH<4),number of reflux episodes > 5 min,percent total time pH<4〕,duration of GERD,esophageal motility parameters〔lower esophageal sphincter resting pressure(LESP),lower esophageal sphincter residual pressure(LESRP),upper esophageal sphincter resting pressure(UESP),upper esophageal sphincter residual pressure(UESRP),contractile front velocity(CFV),distal contractile integral(DCI),lower esophageal sphincter length(LESL)〕.Results A total of 71 cases were enrolled,including 32 with typical presentations,and 39 with atypical presentations.Both groups showed no significant differences in mean age,sex ratio,mean weight and BMI,as well as gastroscopic findings(P>0.05).The incidence of nonerosive reflux disease was higher than that of reflux esophagitis in both groups(P<0.05).Compared with those with atypical presentations,patients with typical presentations had more mean number of reflux episodes(pH<4),greater percent total time pH<4,and shorter duration of GERD(P<0.05),but similar number of reflux episodes >5 min(P>0.05).Moreover,patients with typical presentations also showed lower mean LESP,DCI and LESL,and higher mean UESP and UESRP(P<0.05),but similar mean LESRP and CFV(P>0.05).Conclusion GERD,either with typical or antitypical presentations,more easily occurs in individuals aged 40 to 60 years.The incidence of nonerosive reflux disease is significantly higher than that of reflux esophagitis in these patients.Those with atypical presentations have lower acid reflux degree and more significantly decreased UESP and UESRP,better LESP and esophageal peristalsis function,and longer duration of GERD.

【Abstract】 Background Venous thromboembolism(VTE) is a common underrated vascular disease,but clinical detection methods and risk assessment for it are used insufficiently.Mean platelet volume (MPV) may be one of the important biomarkers for deep venous thrombosis (DVT).Both Padua prediction score and MPV are easily measured parameters with low cost in primary hospitals,and it is of clinical significance to study their combination predictive value for VTE in non-surgical inpatients with D-dimer >500μg/L.Objective To evaluate the combination predictive value of Padua prediction score and MPV for VTE in non-surgical inpatients with D-dimer >500 μg/L.Methods A retrospective analysis was performed on the non-surgical inpatients with highly suspected VTE and D-dimer >500 μg/L selected from the Second People's Hospital of Hefei from February 2017 to April 2019.All of them underwent CT pulmonary angiography or compression ultrasound or venography of the veins in both upper (lower) limbs.Patients were divided into VTE group and non VTE group according to the study criteria.Baseline data were collected,including age,gender,heart rate,D-dimer,Padua prediction score,platelet,MPV,platelet distribution width,platelet thrombocytocrit and mean red blood cell volume.For identifying the risk factors for VTE,baseline parameters were analyzed with univariate Logistic regression initially,then the identified variables with P value less than 0.1 were further analyzed with multivariate Logistic regression.ROC curve analysis was carried out to assess the predictive value of Padua prediction score,MPV,and the combination of the two for VTE.Results There were statistically significant differences in mean Padua prediction score and MPV between VTE and non-VTE groups (P<0.01).Multivariate Logistic regression analysis showed that Padua prediction score〔OR=1.930,95%CI(1.326,2.809),P=0.001〕and MPV 〔OR=2.566,95%CI(1.482,4.444),P=0.001〕were the influencing factors for VTE.For predicting VTE,the AUC of Padua prediction score was 0.723 〔95%CI (0.607,0.839) 〕,with 4.5 for optimal cut-off value,0.600 for sensitivity,0.815 for specificity,and 0.41 for Youden index.The AUC predicted by MPV was 0.771 〔95%CI (0.661,0.881) 〕,with 10.35 fl for optimal cut-off value,0.655 for sensitivity,0.852 for specificity,and 0.51 for Youden index.When Padua prediction score ≥4.5 and MPV ≥10.35 fl,the sensitivity was 0.350,the specificity was 1.000,and the Youden index was 0.35.When Padua prediction score ≥4.5 or MPV ≥10.35 fl,the prediction sensitivity was 0.910,with 0.700 for specificity,and 0.61 for Youden index.Analysis with Z scoring model developed based on the multivariate Logistic regression model using the algorithm of Z=-22+ Padua prediction score+ 2×MPV showed that the AUC of the Z score was 0.851〔95%CI (0.754,0.947) 〕,and when Z ≥1.90,the Youden index was 0.63.Conclusion  Both Padua prediction score and MPV are associated with VTE in non-surgical inpatients with D-dimer >500μg/L,but each has unsatisfactory predictive value.The Z scoring model developed based on the multivariate Logistic regression model proved that the predictive value of the combination of the two may be higher.Padua prediction score ≥4.5 in combination with MPV ≥10.35 fl has high specificity,which may be used as a clinical method for the diagnosis of VTE.
