ABSTRACT
Objective:To summarize the clinical characteristics of patients with acute cholangitis and analyze the early warning factors of death.Methods:The clinical data of patients with acute cholangitis treated in the emergency department of Beijing Friendship Hospital from May 1, 2019 to December 5, 2020 were prospectively selected. The age, gender, vital signs, basic diseases, inflammatory indexes, organ function indexes, coagulation indexes, etiology, emergency drainage and prognosis of cholangitis were analyzed to understand the clinical characteristics of acute cholangitis and find out the strongest early warning factor of 28 day death.Results:A total of 274 patients with acute cholangitis attending the emergency department were examined, which included 265 survival patients (survival group) and 9 deaths (death group). In the death group, the proportion of diabetic patients, white blood cell counts, C-reactive protein, creatinine, international standardized ratio, D-dimer, lactate dehydrogenase, fibrinogen degradation products, Sequential Organ Failure Assessment (SOFA) score were significantly higher than those in the survival group, while the albumin level and Glasgow Coma Scale (GCS) score were significantly lower than those in the survival group (all P<0.05). Multivariate logistic regression analysis showed that GCS score, creatinine level, white blood cell counts and international standardized ratio were the risk factors of death in patients with acute cholangitis (all P<0.05). Conclusions:GCS score, creatinine level, white blood cell counts and international standardized ratio are early warning factors to judge the death of patients with acute cholangitis. GCS score is the strongest predictor of death in patients with cholangitis.
ABSTRACT
Objective:To discuss the effect of acupuncture on learning and memory ability and the expression of neuroglobin (Ngb) of the hippocampus of vascular cognitive impaired (VCI) rats.Methods:VCI rats model was established by repeated ligation of the carotid arteries of the two sides to induce ischemia-reperfusion injury. The successful modeled rats were divided into acupuncture group and a model group according to the random number table method, with 12 rats in each group, and 12 rats were selected as the normal group. The rats in the acupuncture group received acupuncture at "Baihui", "Fengfu" and "Yongquan", 10 times as a course of treatment, a total of 3 courses, and stop acupuncture treatment for 2 days during the courses of treatment. Neurobehavioral scores were measured on the 3rd day after the intervention. Morris water maze was conducted to detect the learning and memory ability of the rats in each group, and Western blot was used to detect the expression of Ngb in the hippocampus of the rats.Results:Compared with the model group, the behavioral score of the acupuncture group decreased after intervention ( P<0.05), the escape latency was significantly shortened ( P<0.05), the number of crossing platforms was increased ( P<0.05), and the hippocampal Ngb (1.18±0.06 vs.0.98±0.04) was significantly increased ( P<0.05). Conclusion:Acupuncture at "Baihui", "Fengfu" and "Yongquan" could promote the expression of Ngb in the hippocampus of rats and improve the learning and memory ability of VCI rats.
ABSTRACT
Objective:To evaluate direct bilirubin /total bilirubin(D/T), B-mode ultrasound(BUS), multislice spiral computed tomography (MSCT), magnetic resonance cholangiopancreatography (MRCP) and endoscopic ultrasound (EUS) in the diagnosis of choledocholithiasis abdominal pain (CAP).Methods:We retrospectively analyzed the materials of patients who were diagnosed with choledocholithiasis abdominal pain by above imagines in the emergency department of Beijing Friendship Hospital during March 2016 to December 2018. The stones were taken out by endoscopic retrograde cholangiopancreatography or surgical operation as the golden standard.Results:Among 256 patients, 195 cases, 138 cases, 107 cases and 26 cases were diagnosed by EUS, MRCP, CT and BUS, respectively. The sensitivity were 0.86, 0.62, 0.45, 0.13, respectively. The specificity were 0.86, 0.81, 0.75, 0.87. The positive predictive value were 0.97, 0.96, 0.91, 0.83.The negative predictive value were 0.55, 0.19, 0.21, 0.16. The accuracy rate were 0.88, 0.64, 0.48, 0.30, respectively. The sensitivity of D/T and D/T combined with EUS in the diagnosis of CAP were 0.57 and 0.67, and the accuracy were 0.16 and 0.56, respectively.Conclusions:EUS has a high diagnostic value for CAP. MRCP is superior to CT in the value of diagnosis of CAP. BUS in imaging diagnosis of CAP value is relatively low, but D/T combined with BUS can improve the sensitivity and accuracy of diagnosis for CAP.

ABSTRACT
Tumor cells along with a small proportion of cancer stem cells exist in a stromal microenvironment consisting of vasculature, cancer-associated fibroblasts, immune cells and extracellular components. Recent epidemiological and clinical studies strongly support that vitamin D supplementation is associated with reduced cancer risk and favorable prognosis. Experimental results suggest that vitamin D not only suppresses cancer cells, but also regulates tumor microenvironment to facilitate tumor repression. In this review, we have outlined the current knowledge on epidemiological studies and clinical trials of vitamin D. Notably, we summarized and discussed the anticancer action of vitamin D in cancer cells, cancer stem cells and stroma cells in tumor microenvironment, providing a better understanding of the role of vitamin D in cancer. We presently re-propose vitamin D to be a novel and economical anticancer agent.
ABSTRACT
Objective To explore the relationship between those myocardial markers serum cardiac troponin T (cTNT),serum cardiac troponin I (cTNI),N-terminal pro-brain natriuretic peptide (NT-proBNP),echocardiography and myocardial injury in the oldest-old septic patients,as well as to evaluate prognosis in the oldest-old septic patients.Methods 140 oldest-old septic patients hospitalized in Beijing Friendship Hospital from January 1 st,2015 to Jun 31st,2017 were collected and analyzed retrospectively.They were divided into survival group (90 cases) death group (50 cases)according to their survival time.Serum cTNT,cTNI and NT-proBNP level at 1,3 and 7d post-diagnosis were collected and echocardiography left ventricular diastolic diameter (EDD),left ventricular systolic diameter (ESD),right ventricular diameter (RV),left ventricular ejection fraction (EF) was performed.Results 140 oldest-old septic patients were enrolled in the analysis.There were 90 cases in survival group and 50 cases in death group.Mean values of cTNT,cTNI,NT-proBNP,EDD,ESD in survival group were obviously higher than those in death group (P ＜ 0.05),left ventricular ejection fraction (LVEF) in survival group was lower than that in death group (P ＜ 0.01).But there were no difference in E/A and RV between survival group and death group (P ＞ 0.05).There were positive correlation between cTNT,cTNI,NT-proBNP and EDD,ESD (P ＜ 0.05),negative correlation between cTNT,cTNI,NT-proBNP and LVEF (P ＜ 0.05),and no correlation between cTNT,cTNI,NT-proBNP and E/A,RV (P ＞0.05).There were obviously correlation between cTNT,cTNI,NT-proBNP,EDD,ESD and mortality rate (OR ＞ 1,P ＜ 0.05).It was shown the prognosis value of cTNT,cTNI,NT-proBNP,EDD,ESD to mortality rate in oldest-old septic patient.The prognosis value was cTNT ＞ NT-proBNP ＞ cTNI ＞ EDD ＞ ESD.Conclusions There were obviously correlation between cT NT,cTNI,NT-proBNP,EDD,ESD and myocardium restrain,heart dysfunction as well as mortality rate.cTNT was the best prognosis indicator in sensitivity,and NT-proBNP was the best prognosis indicator in specificity.The combination of cTNT and NT-proBNP can better forecast the prognosis of the oldest-old septic patient.
ABSTRACT
Objective To observe the occurrence of myocardial apoptosis and discussing the mechanism of the effects of glucocorticoid on myocardial apoptosis in septic rats in order to provide the rationale for clinical strategy.Methods A total of 60 Wistar rats weighing 230-280 g were randomly (random number) divided into control group and experimental group (n =30 in each group).Cecal ligation and puncture (CLP) was performed in rats to induce sepsis,and Cefoperazone Sodium/Sulbactam Sodium (200 mg/kg) was injected into caudal vein 4 hours after CLP,twice a day.In addition,glucocorticoid was given to rats of experimental group.After rats sacrificed,their left ventricular myocardia were rapidly taken out and myocardial apoptosis rate was measured and the level of Bcl-2 was assayed at 6 h,24 h,and 72 h after CLP.Measured data were analyzed with independent-samples t-test and One-Way ANOVA.Results The rates of myocardial apoptosis in experimental group were obviously lower than those in control groups respectively (F=9.11,t=5.681,P＜0.01) (6ht=11.416,P＜0.01; 24ht=6.217,P＜0.01; 72 h t =3.76,P ＜0.01).The rates of myocardial apoptosis in 24 h in control and 72 h control groups were distinctively higher than those in 6 h control group,respectively (F =13.254,sig =0.000,P ＜0.01 ; sig =0.004,P ＜ 0.01).The rates ofmyocardial apoptosis in group 24 h control were higher than those in 72 h control group (sig =0.039,P ＜ 0.05).The rates of myocardial apoptosis make no difference among experimental group (F =2.488,6/24 h sig =0.132,P ＞ 0.05 ; 24/72 h sig =0.549,P ＞ 0.05 ; 6/72 h sig =0.053,P ＞ 0.05).Conclusions The rate of myocardial apoptosis is peaked at 24 h in sepsis rat,and the rate of myocardial apoptosis can be obviously decreased by administration of glucocorticoid.
ABSTRACT
ObjectiveTo investigate the health status and incidence of alcohol abuse of Xinjiang community residents.MethodsThrough multi-stage random sampling,1992 community residents ( 15-65years old) were assessed using socio-demographic information questionnaire,alcohol use disorders identification test (AUDIT) and self-rated health measurement scale-prior test(SHRMS).Single factor analysis and rank sum test were used to identify the incidence of alcohol abuse,the distribution of different populations,and the self-rated health status of abusers.ResultsTotally 298 cases of alcohol abuse were identified,and accordingly,the prevalence rate of alcohol abuse for general population was 15.1％ ( male 26.4％,female 4.8％ ).Key factors for alcohol abuse included male,middle-aged,well-educated,at work,administrative work,high income levels and large number of household.The differences among groups were statistical significant.Presumably the workplace population was at high risk of alcohol abuse.Alcohol abusers were significantly worse than general population in self-rated health status(P ＜ 0.01 ),especially in mental health and social health.ConclusionThe incidence of alcohol abuse is relatively high in Xinjiang rcgion,and the problem need more attention.Further survey and early intervention work for highrisk group are advised to achieve the purpose of prevention and control.
ABSTRACT
Objective To investigate the diagnostic value of 16 ku-38 ku-ESAT-6 protein in tuberculosis (TB). Methods ELISA was used for measuring the level of recombinant 16 ku-38 ku-ESAT-6 protein in 105 TB patients (TB group,26 patients with smear-positive, 79 patients with smear-negative) and 45 controls (control group, 20 healthy volunteers and 25 subjects with pulmonary diseases other than TB). The value of the antigen for diagnosis of TB in serodiagnosis was assessed, and ROC curve evaluation system was established. Results In control group, the positive rate of anti-recombinant 16 ku-38 ku-ESAT-6 protein and commercialization of TB antibody test kit had significant difference [6.67% (3/45) vs. 51.11% (23/45)](P＜0.01);but in TB group, there was no significant difference [59.05%(62/105) vs. 64.76% (68/105)](P＞0.05). The optical density value in TB group and control group was 2.22 ± 0.58 and 1.35 ± 0.24,and there was significant difference(t = 6.06,P＜ 0.01). The sensitivity, specificity, positive predictive value and negative predictive value of the test was 59.05%,93.33%,95.38%,49.41% respectively. Analyzed by ROC curve, the area under the curve was 0.751, the- value of cutoff was 2.52, and sensitivity and specificity was 65.4% and 84.8%. Conclusions Recombinant 16 ku -38 ku -ESAT-6 protein of mycobacterium tuberculosis has higher specificity, and it can significantly distinguish TB and non-TB. So it might be selected as one of diagnosis antigens of TB.
