ABSTRACT

Objective To investigate the application value of transjugular liver biopsy (TJLB) in the diagnosis and treatment of complicated and severe liver diseases. Methods A retrospective analysis was performed for the clinical data of 31 patients who underwent TJLB in The Fifth Medical Center of Chinese PLA General Hospital, including indication for puncture, success rate, and final diagnosis. Results Among the 31 patients, there were 15 male patients and 16 female patients. Percutaneous liver biopsy was unsuitable for 8 patients with liver failure and disturbances of blood coagulation, 13 with liver cirrhosis and ascites, and 10 with liver cirrhosis and thrombocytopenia (< 50×10 9 /L), which were the indications for TJLB. The success rate of TJLB puncture was 100%, with 2-4 passes for puncture. No serious adverse event was observed. Of all 31 patients, 26 (83.87%) had a definite diagnosis at discharge, among whom there were 5 patients with idiopathic portal hypertension, 9 patients with drug-induced liver failure or liver cirrhosis, 5 patients with autoimmune liver disease, and 7 patients with liver cirrhosis or liver failure due to other causes, and 5 patients had unknown etiology. In addition, 3 patients underwent biopsy to confirm the diagnosis and decision of whether liver transplantation should be performed. Conclusion TJLB plays an important role in the diagnosis and treatment of complicated and severe liver diseases and still has certain limitations, and therefore, suitable patients should be selected in clinical practice.

ABSTRACT

Objective@#To establish and evaluate diagnostic efficacy and applicability of serum Golgi protein (GP) 73 based non-invasive diagnostic model with other conventional serological indicators for compensated stage hepatitis B cirrhosis.@*Methods@#666 cases with chronic hepatitis B (CHB) who had visited to the Fifth Medical Center of People’s Liberation Army General Hospital from January 2010 to December 2017 were selected as the study subjects, and were classified according to compensated stage cirrhosis into clinical and pathological diagnosis group based on whether or not the liver histological examination was performed. A diagnostic model of compensated stage hepatitis B cirrhosis in the clinical diagnosis group was established. The current clinically used diagnostic model of liver cirrhosis, aspartate aminotransferase/platelet ratio index (APRI), fibrosis index (FIB)-4 and liver stiffness measurement (LSM) were compared. Eventually, the diagnostic model was verified step by step by pathological diagnosis group.@*Results@#The area under the receiver operating characteristic curve (AUC) of GP73 and APRI, FIB-4, and LSM for cirrhosis patients in the clinical diagnosis group were 0.842, 0.857, 0.864, and 0.832, respectively. The diagnostic efficiency of the four indicators were of similar (P value > 0.05). A diagnostic model of compensated stage hepatitis B cirrhosis (GAPA) using logistic regression analysis was established: LogitP = 1/ [1 + exp (1.614-0.054 × GP73-0.045 × Age + 0.030 × PLT-0.015 × ALP)]. The AUC of the model was as high as 0.940 and the optimal cut-off value were 0.41. The corresponding diagnostic sensitivity and specificity were 0.92 and 0.82, respectively. The diagnostic efficiency was better than that of APRI, FIB-4, LSM and GP73 alone (P < 0.05). The AUC of GAPA was 0.877 in the pathological diagnosis group, which was similar to the diagnostic efficacy of LSM (0.891) and FIB-4 (0.847) (P > 0.1), but still superior to that of APRI (0.811) and GP73 alone (0.780) (P < 0.001).@*Conclusion@#GAPA, a diagnostic model for compensated stage hepatitis B cirrhosis established in this study, has a good diagnostic efficacy in both the clinical and pathological diagnosis group, and has certain auxiliary diagnostic value in the areas where resources are relatively scarce or where LSM has not been developed.

ABSTRACT

Objective:To investigate the relationship between the down-regulation expression of sodium taurocholate cotransporting polypeptide (NTCP) in proliferating hepatocytes and the response to antiviral therapy of chronic hepatitis B (CHB) patients.Methods:Sixty-eight hepatitis B e antigen (HBeAg)-positive CHB patients admitted to the Fifth Medical Center of PLA General Hospital from January 2011 to March 2015 were included. Basic information and laboratory data were collected. Based on the baseline (before antiviral treatment) inflammatory activity (G), the patients were divided into ≤G2 group and >G2 group. Twelve liver puncture tissue samples were selected from each group for NTCP and Ki67 immunofluorescence staining.The proportion of Ki67-positive cells was calculated, and the staining of NTCP was scored. Five pairs of tissue specimens of patients who had hepatitis B virus (HBV) infection were diagnosed with focal nodular hyperplasia (FNH) and underwent nodular resection surgery from March 2014 to March 2017 were collected.Immunohistochemical staining was used to detect the expressions of Ki67, NTCP and hepatitis B surface antigen (HBsAg) in each tissue specimen, and the proportion of staining positive cells or the staining intensity was calculated. Statistical analysis was performed by Mann-Whitney U test, chi-square test or Spearman correlation analysis. Results:The proportion of Ki67-positive cells (6.75%(6.20%, 8.16%))in five liver FNH tissues with HBV infection was significantly higher than that in adjacent non-FNH tissues (0.75%(0.66%, 1.20%)), while the immunohistochemical scores of NTCP and HBsAg (3.00 (1.00, 3.00) and 2.00 (1.00, 2.00), respectively) were both significantly lower than those in adjacent non-FNH tissues (8.00 (8.00, 9.00) and 8.00 (6.00, 8.00), respectively), the differences were all statistically significant ( Z=-2.611, -2.424 and -2.635, respectively, P=0.009, 0.015 and 0.008, respectively). There were 37 patients in >G2 group, and 31 patients in ≤G2 group. After six months of antiviral treatment, CHB patients with persistent inflammation in >G2 group obtained a better virological response, with serum HBV DNA and HBeAg showing a greater decline ((0.71±0.14) lg IU/mL and (0.92±0.13) lg IU/mL, respectively) than those in ≤G2 group ((0.54±0.30) lg IU/mL and (0.49±0.65) lg IU/mL, respectively) ( Z=-3.048 and -2.666, respectively, P=0.002 and 0.008, respectively). The proportion of Ki67-positive cells in the specimens of >G2 group (4.34%(1.84%, 8.77%)) was significantly higher than that of ≤G2 group (0.34%(0, 0.80%)) ( Z=-3.640, P<0.01), and the immunohistochemical staining score of NTCP (1.00 (0, 3.25)) was significantly lower than that of ≤G2 group (6.00 (4.00, 8.00)) ( Z=-3.012, P=0.003). Spearman correlation analysis showed that the NTCP immunohistochemical score was negatively correlated with the proportion of Ki67-positive cells ( r=-0.512, P=0.01). Conclusions:CHB patients with persistent inflammationare often accompanied by more active hepatocyte proliferation and low membrane NTCP expression, which is not conducive to HBV reinfection. It may facilitate these patients to obtain better virological response.

ABSTRACT

Acute ischemic stroke (AIS), as the third leading cause of death worldwide, is characterized by its high incidence, mortality rate, high incurred disability rate, and frequent reoccurrence. The neuroprotective effects of Ginkgo biloba extract (GBE) against several cerebral diseases have been reported in previous studies, but the underlying mechanisms of action are still unclear. Using a novel in vitro rat cortical capillary endothelial cell-astrocyte-neuron network model, we investigated the neuroprotective effects of GBE and one of its important constituents, Ginkgolide B (GB), against oxygen-glucose deprivation/reoxygenation and glucose (OGD/R) injury. In this model, rat cortical capillary endothelial cells, astrocytes, and neurons were cocultured so that they could be synchronously observed in the same system. Pretreatment with GBE or GB increased the neuron cell viability, ameliorated cell injury, and inhibited the cell apoptotic rate through Bax and Bcl-2 expression regulation after OGD/R injury. Furthermore, GBE or GB pretreatment enhanced the transendothelial electrical resistance of capillary endothelial monolayers, reduced the endothelial permeability coefficients for sodium fluorescein (Na-F), and increased the expression levels of tight junction proteins, namely, ZO-1 and occludin, in endothelial cells. Results demonstrated the preventive effects of GBE on neuronal cell death and enhancement of the function of brain capillary endothelial monolayers after OGD/R injury in vitro; thus, GBE could be used as an effective neuroprotective agent for AIS/reperfusion, with GB as one of its significant constituents.

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the correlation of serum osteoprotegerin (OPG) with the progression of nonalcoholic fatty liver disease (NAFLD) and the noninvasive prediction and diagnosis of nonalcoholic steatohepatitis (NASH).</p><p><b>METHODS</b>A total of 136 patients with NAFLD were enrolled, and their tissue samples for liver biopsy and serum samples obtained at 1 week after liver biopsy were collected; 83 healthy subjects without the symptoms of fatty liver disease proved by ultrasound examination were enrolled as controls. The physiological indicators including height, body weight, and waist circumference were measured, and body mass index was calculated. The biochemical parameters including alanine aminotransferase (ALT), aspartate aminotransferase (AST), AST/ALT, alkaline phosphatase, gamma-glutamyl transferase, total cholesterol, triglyceride (TG), high-density lipoprotein cholesterol, and low-density lipoprotein cholesterol were measured. Double-antibody sandwich enzyme-linked immunosorbent assay was used to determine the serum level of OPG. The rank sum test, chi-square test, t-test, one-way analysis of variance, Spearman correlation analysis, least significant difference test, and receiver operating characteristic (ROC) curve were applied for statistical analysis of various data.</p><p><b>RESULTS</b>Serum OPG level was correlated with AST and TG (P < 0.05), and was highly correlated with hepatocyte fatty degeneration, ballooning degeneration, intralobular inflammation, portal inflammation, and fibrosis degree (P < 0.01). With the increasing NAFLD activity score (NAS), serum OPG level decreased, and there was a highly negative correlation between them (r = -0.928, P < 0.01). Serum OPG level was significantly lower in NASH patients than non-NASH patients. The area under the ROC curve of serum OPG level was 0.963, and according to the Youden index, its optimal sensitivity and specificity were 96.1% and 97.4%, respectively, at an optimal cut-off value of 242.96 ng/L, which suggested a high diagnostic power.</p><p><b>CONCLUSION</b>In NASH patients, serum OPG level decreases significantly. Serum OPG level can be used as an independent predictive factor to evaluate NASH and its severity, as well as a noninvasive diagnostic index for NASH.</p>

ABSTRACT

Objective To investigate the mortality risk factors of nosocomial infection patients in intensive care unit (ICU), and to guide clinicians to take effective control measures. Methods A retrospectively cohort study was conducted. The relevant information of patients with nosocomial infection treated in ICU of Hengshui Harrison International Peace Hospital Affiliated to Hebei Medical University from June 2009 to December 2015 was analyzed. The patients who admitted to ICU again, with length of ICU stay less than 48 hours, without first etiology of screening within 48 hours of ICU admission, or without complete pathogenic information were excluded. The gender, age, diagnosis, length of ICU stay, invasive operation, nutritional status, acute physiology and chronic health evaluation Ⅱ (APACHEⅡ) score, sequential organ failure assessment (SOFA) score, distribution and drug resistance of the pathogens, and procalcitonin (PCT) levels at 7 days after nosocomial infection were recorded. The risk factors leading to death in patients with nosocomial infection were analyzed by logistic regression, and the receiver operating characteristic curve (ROC) was drawn to evaluate the predictive value of all risk factors on the outcome of patients with nosocomial infection. Results In 864 enrolled patients with male of 54.75% and mean age of (63.50±15.80) years, 732 (84.72%) patients survived and 132 (15.28%) died. Compared with survivors, the non-survivors had higher age (years: 65.47±15.32 vs. 58.15±13.27), incidence of urgent trachea intubation (32.58% vs. 22.81%), deep venous catheterization (83.33% vs. 63.25%), and multiple drug-resistant infection (65.91% vs. 33.20%), longer length of ICU stay (days: 13.56±4.29 vs. 10.29±4.32) and duration of coma (days: 7.36±2.46 vs. 5.48±2.14), lower albumin (g/L: 23.64±8.47 vs. 26.36±12.84), higher APACHEⅡ score (19.28±5.16 vs. 17.56±5.62), SOFA score (8.55±1.34 vs. 6.43±2.65), and PCT (μg/L: 3.06±1.36 vs. 2.53±0.87, all P 0.05). The low respiratory tract was the most common site of infection followed by urinary tract and bloodstream in both groups. It was shown by logistic regression analysis that prolonged ICU stay [odds ratio (OR) = 2.039, 95% confidence interval (95%CI) = 1.231-3.473, P = 0.002], APACHEⅡ score (OR = 1.683, 95%CI= 1.002-9.376, P = 0.000), SOFA score (OR = 2.060, 95%CI = 1.208 -14.309, P = 0.041), PCT (OR = 2.090, 95%CI = 1.706-13.098, P = 0.004), and multi-drug resistant pathogens infection (OR = 5.245, 95%CI = 2.213-35.098, P = 0.027) were independent risk factors for ICU mortality in patients with nosocomial infection. The area under ROC curve (AUC) of length of ICU stay, APACHEⅡ score, SOFA score, and PCT level for predicting death of nosocomial infection patients was 0.854, 0.738, 0.786, and 0.849, respectively, the best cut-off value was 16.50 days, 22.45, 6.37 and 3.38 μg/L, respectively, the sensitivity was 83.6%, 90.0%, 81.1%, and 89.6%, and the specificity was 70.3%, 75.6%, 71.3%, and 85.4%, respectively. Conclusions Prol onged ICU stay, nosocomial infection with secondary sepsis and multiple organ dysfunction syndrome were the leading causes of death for nosocomial infection patients in ICU. Prolonged ICU stay, APACHE Ⅱ score, SOFA score, and PCT level could effectively predict death risks for nosocomial infection patients.

ABSTRACT

Objective To look for suitable short-term weight loss and long-term maintenance method for army cadres. Method A total of 142 patients with simple overweight and obesity were randomly selected as the research subjects, and were followed up for 2 years, 130 of them were valid for analysis, 97 were male, and 33 female, age 27-59 years, average(47.41±7.55)years. SPSS 16.0 was used for analysis. Repeated measurements analysis of variance was used for data analysis, K-related samples nonparametric test was used for enumeration data. Result The army cadres population weight intervention management model was divided into three stages. They were respectively intensified weight loss stage for 6 months, the consolidation of weight loss for 6 months, and self-management stage maintained for 12 months, totally 24 months. Variance analysis results showed that after two years of focused intervention and health management, the body mass index(BMI)fell from(27.42 ± 2.81)kg/m2 to(24.69 ± 2.63)kg/m2 (F=2 649.945, P<0.05), waist circumference decreased from(91.09±8.24)cm to(85.26±7.76)cm(F=1 207.248, P<0.05). Nonparametric test results showed that after two years intervention management the behavior patterns concerning physical exercise became better. Exercisers increased from 33.8%to 73.3%(H=68.448, P<0.05); proportion of smoking decreased from 38.5% to 20.0%(H=33.692, P<0.05); drinking alcohol decreased from 50.8%to 20.8%(H=59.128, P<0.05);high salt diet decreased from 39.2%to 23.1%(H=31.722, P<0.05);high-fat diet decreased from 46.2%to 27.7%(H=41.571, P<0.05). Conclusion The practice showed that the short-term intensified weight loss, long-term maintenance, exercise and psychological intervention, changed the cadres population from passive to active on the weight control and self-management with remarkable effects, therefore such intervention is worthy of promoting.

ABSTRACT

Objective To evaluate the clinical value of tube-sealing with norvancomycin and heparin saline mixture for prevention of central venous catheter-related infection (CRI).Methods A prospective randomized controlled trial was performed.120 patients who were admitted to department of critical care medicine from January 2012 to January 2014 were included,with their subclavian vein catheterization installation time longer than 48 hours,age over 18 years and younger than 80 years,and acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score reaching 10-29.The patients were divided into two groups using a random number table,and finally 116 patients were enrolled.Norvancomycin and heparin saline mixture were used for tube sealing in the intervention group (n=56),while only heparin saline was used in the control group (n=60).The incidence of CRI,catheter correlated spectrum of pathogens,adverse events,mortality,hospital day,catheter retention time,and hospital costs were compared between two groups.Results ① There was no significant difference in the incidence of CRI between intervention group and control group [7.14% (4/56) vs.8.33% (5/60),x2=0.058,P=1.000].There was no catheter pathogenic colonization in the intervention group,but there were 2 cases of catheter pathogenic colonization in control group.② A total of 7 pathogens were found in two groups.Three cases with pathogenic bacteria was found in the intervention group,with 1 case of Pseudomonas aeruginosa,1 case Acinetobacter baumannii,and 1 case fungi.Staphylococcus aureus,Staphylococcus epidermidis,fungi,and Acinetobacter baumannii was found in the control group,with 1 case of each.There was no significantly statistical difference between two groups (all P>0.05),but there was a decreasing trend of Gram-positive cocci infection in the intervention group.③ There was no significant difference in the catheter thrombosis,local bleeding or hematoma,catheter dislocation and other adverse events between intervention group and control group [21.43%(12/56) vs.23.33% (14/60),x2=0.060,P=0.806].④ There were no significant differences in mortality [7.14%(4/56) vs.8.33% (5/60),x2=0.058,P=1.000],hospital day (days:35.9 ± 15.2 vs.34.1 ± 16.3,t=16.330,P=0.620),catheter retention time (days:25.0 ± 4.5 vs.24.5 ± 5.1,t=26.427,P=2.560) and cost of hospitalization (10 thousand Yuan:3.42 ± 1.22 vs.3.72 ± 1.30,t=13.215,P=1.560) between intervention group and control group.Conclusions For patients with central venous catheter,application norvancomycin with heparin saline mixture for tube sealing did not reduce the incidence of CRI,the incidence of adverse events and mortality,does not reduce hospitalization time,catheter retention time and hospital costs,but may reduce the catheter colonization and infection of Gram-positive bacteria.

ABSTRACT

Objective To explore the effect of the transcutaneous tracheostomy tube in patients with pneumothorax and its clinical value. Methods A prospective randomized controlled trial was conducted. Thirty-two patients with pneumothorax admitted to Department of Critical Care Medicine of Harrison International Peace Hospital of Hebei Medical University from June 2010 to June 2014 were enrolled. The patients were divided into control group and observation group,with 16 cases in each group. Beside the treatment for primary disease,the patients in control group received thoracic close drainage with traditional silica gel tube as performed by thoracic surgeons,and those in observation group received thoracic close drainage with transcutaneous tracheostomy tube by intensive care doctors. The curative effect and complications of the two groups were observed. Results Compared with control group,the time from diagnosis to operation(minutes:8.00±1.36 vs. 23.06±3.83,t=14.790,P=0.000)and the operation time were significantly shortened(days:5.37±1.02 vs. 7.31±1.70,t=7.286,P=0.000),the frequency of drainage tube replacement(times:0.18±0.40 vs. 3.87±1.14,t=12.128,P=0.000)and the times of repeated chest radiography(times:1.12±0.34 vs. 2.93±0.77,t=8.589,P=0.000)in observation group were significantly reduced,the length of hospital day was significantly shortened(days:8.30±1.37 vs. 24.56±5.62,t=17.289, P=0.000),the rates of dislocation of drainage tube(0 vs. 3 cases),obstruction of the tube(0 vs. 5 cases),and subcutaneous emphysema(3 vs. 16 cases)were reduced obviously,but there was no difference in incidence of incision infection(1 vs. 3 cases)and infection of thoracic cavity(0 vs. 2 cases). Conclusions The usage of transcutaneous tracheostomy tube in patients with pneumothorax is safe and simple. Doctors in ICU can independently do this procedure,and its effect is positive.

ABSTRACT

BACKGROUND:Studies have confirmed that the active ingredients ofPaeonia lactiflora Pal. have better inhibitory effects onCandida albicans, but its monomer paeoniflorin has not been reported whether it can inhibit Candida albicans biofilm. OBJECTIVE:To observe the effect of paeoniflorin onCandida albicans biofilm in vitro. METHODS:Paeoniflorin solution at different concentrations of 4, 2, 1, 0.5, 0.25 g/L was prepared using RPMI-1640 according to 2-fold dilution method. Chlorhexidine was diluted with RPMI-1640 to different concentrations, including 2%, 1%, 0.5%, 0.25%, 0.125%. We compared the effects of different concentrations of chlorhexidine and paeoniflorin on diameter ofCandida albicans by agar diffusion method. MTT assay was used to detect the effect of different concentrations of chlorhexidine or paeoniflorin on the celladhesion of Candida albicans as wel as their inhibitory effects onCandida albicans biofilms. Confocal laser scanning microscope and LIVE/DEAD BacLight Bacterial Viability Kits were combined to observe the changes ofCandida albicans biofilms under normal or intervention conditions. RESULTS AND CONCLUSION:Both chlorhexidine and paeoniflorin possessed bacteriostatic ability, and their bacteriostatic ring diameters were positively correlated with drug concentrations. Significant differences in the bacteriostatic ring diameter were observed between chlorhexidine and paeoniflorin, except between 2 g/L paeoniflorin and 1%, 2% chlorhexidine. Paeoniflorin at different concentration could inhibit celladhesion of Candida albicans as wel as inhibitCandida albicans biofilm. The inhibition rate was also positively correlated with drug concentrations. Under normal conditions, most of bacteria in the biofilms were alive, and there was a smal amount of dead bacteria after 48 hours. After intervention with paeoniflorin, the proportion of dead bacteria in the biofilms was increasing along with the concentrations of paeoniflorin. Compared with the chlorhexidine, paeoniflorin showed a lower bacteriostatic activity. These findings indicate that paeoniflorin has an obvious inhibitory action in Candida albicans biofilms in vitro.

ABSTRACT

Objective To investigate the effects of early tracheotomy on the prognosis of patients with severe brain lesions .Methods The clinical data of 68 patients with severe brain lesions were retrospectively analyzed . According to the time of tracheotomy ,we assigned 68 patients to receive either early tracheotomy or late tracheotomy . 34 patients who were given tracheotomy within 72 hours in Intensive Care Unit were selected as the early tracheotomy group (ET group).34 patients who were given tracheotomy after 14 days in Intensive Care Unit were selected as the late tracheotomy group(LT group).The time of mechanical ventilation,length of hospital stay,and the incidence of ventilator associated pneumonia ( VAP ) , sedative drug use time , antibiotic use time , in-hospital mortality were compared between the two groups.Results In ET group,the hospitalization time,mechanical ventilation time, incidence of VAP,sedative drug use time,antibiotic use time were (4.2 ±2.4)d,(3.5 ±0.6)d,(14.5 ±3.2)%, (1.5 ±0.5)d,(3.3 ±0.3)d,those in LT group were (12.5 ±4.8)d,(8.5 ±5.6)d,(28.6 ±8.6)%,(6.3 ±1.2)d, (13.2 ±1.1) d respectively,the differences between the two groups were statistically significant ( t =3.14,2.96, 3.28,3.46,2.57,all P<0.05).The hospitalization mortality rates of ET group ,LT group were (23.8 ±4.38)%, (24.5 ±4.16)%,respectively no significant difference between the two groups ( t=1.49,P<0.05).Conclusion The use of early tracheotomy can reduce the hospitalization time ,shorten the time of mechanical ventilation ,reduce the incidence of ventilator associated pneumonia ,and reduce the time of using sedative drugs and antibiotics ,but the mor-tality has no significant effect in the severe craniocerebral injury patients .

ABSTRACT

Objective Motility is an important physiological characteristic of a mature sperm.Nerve growth factor(NGF) is a protein essential for the development,maintenance and survival of the peripheral and central nervous systems.NGF and its receptors TrkA and p75 are widely expressed in the testis,accessory reproductive organ,and the epididymal sperms.In the present study,we investigated the role of NGF on human sperm motility.Methods Use 0.1,1 and 10 μmol/L concentrations of NGF,on sperm motility study to investigate the optimal concentration.Use CASA to detect Sperm motility changes every 10 minutes in an hour after 10 μmol/L NGF was added to the semen.Results The parameters of sperm motility increased after NGF incubation had significant difference, in particular,VAP,VSL,VCL,BCF and LIN mean were significantly increased more than 32%.MAD,STR,ALH and WOB mean had no notable difference.Furthermore,NGF promotes the sperm motility in a time- and dose- dependent manner.In addition,the enhancement of NGF on sperm motility was more stronger than those of sperm culture medium.Conclusion Our findings suggest that NGF plays a promoted role in human sperm motility.
