ABSTRACT
Objective To evaluate the value of bedside ultrasound-measured antral cross-sectional area (CSA) in diagnosing an empty stomach in patients with chronic hepatitis B.Methods One hundred and fifty-nine patients with chronic hepatitis B,aged 18-64 yr,with body height＞150 cm,weighing 45-110 kg,were enrolled in this study.The antero-posterior diameter and craniocaudal diameter of the gastric antrumn were measured by bedside ultrasound when patients were in the supine position,and CSA was calculated.Gastroscope negative pressure was used to suction fluid from stomach at the end of gastroscopy,and the fluid volume was recorded,and gastric fluid volume ≤0.8 ml/kg was defined as the standard for empty stomach.Results The cut-off value of CSA measured by bedside ultrasound in diagnosing an empty stomach was 440 mm2,with sensitivity 85.07％,specificity 80.95％,positive predictive value 96.61％,negative predictive value 45.95％,coincidence rate 84.52％.Conclusion The cut-off value of bedside ultrasound-measured CSA in diagnosing an empty stomach is 440 mm2 for the patients with chronic hepatitis B.
ABSTRACT
Objective The plasma levels of interleukin 6 (IL-6),high sensitive C reactive protein (hs-CRP) and the level of T cell activation were detected in the peripheral blood inflammatory factors of acquired immunodeficiency syndrome (AIDS) patients,and the relationship with opportunistic infection and prognosis was analyzed.Methods 79 human immunodeficiency virus (HIV)-positive/aids cases from May 2014 to January 2015 in first hospital of Changsha were enrolled in the study.They were divided into three groups:HIV-infected without opportunistic infections group (n =20),HIV-infected with infections group (n =43,including HIV-infected with tuberculosis group,HIV-infected with merge fungus group.HIV combined hepatitis C),death group (n =16).Serum IL-6 and the concentration of hs-CRP were detected by enzyme-linked immunosorbent assay (ELISA).Flow cytometry was used to test the CD3 + CD4 + cell count,the percentage of CD4 + CD38 + cell and CD8 + CD38 + cell in peripheral blood mononuclear cell (PBMC).Compare the differences among the three groups.Results The results showed that:the concentration of hsCRP and IL-6 in peripheral blood of HIV death group was significantly higher than that in other three groups (P ＜ 0.05).The concentration of hs-CRP and IL-6 in the peripheral blood of the HIV-infected with tuberculosis group and HIV-infected with merge fungus group were significantly higher than that in the HIV-infected without opportunistic infections group (P ＜ 0.05),and the hs-CRP in the peripheral blood of the HIV combined with the hepatitis C group was higher than that in the HIV-infected without opportunistic infections group (P ＜ 0.05).The number of CD3,CD4T lymph nodes in the death group and the combined opportunistic infection group was significantly lower than that in the HIV-infected without opportunistic infections group (P ＜ 0.05).The HIV-RNA expression in peripheral blood of the death group and the combined opportunistic infection group was significantly lower than that in the HIV-infected without opportunistic infections group (P ＜ 0.05).The expression of CD8+CD38+ on PBMC in the HIV-infected without opportunistic infections group was significantly lower than that in the death group,the tuberculosis group,the fungus group and the hepatitis C group (P ＜ 0.05).The expression of CD4+ CD38 + on PBMC in the HIV-infected without opportunistic infections group was higher than that in the death group (P ＜ 0,05).Conclusions The concentration of inflammatory cytokines (IL-6,hs-CRP) and the expression level of T cell surface CD8 + CD38 + related to immune activation were associated with opportunistic infection and prognosis of AIDS.
ABSTRACT
Objective To explore sensitive indicators for the initiation,development,and metastasis of gastric cancer and to provide objective evidence for the early diagnosis,treatment,and progression monitoring of gastric cancer.Methods A total of 108 patients with gastric cancer were enrolled in this study.The expression of interleukin receptor 1 (CXCR1)in samples from gastric cancer and adjacent tissues was detected by immunohistochemistry and patient clinical data were collected for correlation analysis.Logistic regression analysis of the 5-year survival rate of patients was conducted.Results The positive CXCR1 expression rate in gastric neoplasm tissues was significantly higher than that in adjacent tissues.Nevertheless,CXCR1 was correlated with tumor differentiation (P =0.017),TNM staging (P =0.006),and the existence of lymphatic metastasis (P =0.035).The overall survival rate (P =0.043) and recurrence-free survival rate (P=0.029) of patients with positive CXCR1 were lower than those of patients with negative CXCR1.Conclusions CXCR1 expression levels increase in gastric neoplasm tissues and are associated with tumor differentiation,TNM staging,and lymphatic metastasis.Positive CXCR1 is correlated with poor prognosis and has the potential to serve as one of clinical prognostic indicators.
ABSTRACT
Objective To explore the therapeutic effect and prognosis of enhanced external counterpulsation (EECP)on acute cerebral ischemic stroke,to provide clinical evidence for the treatment of patients with acute cerebral ischemic stroke.Methods Total171 patients with acute cerebral ischemic stroke were enrolled and measured the NIHSS and mRS,before EECP,after36 hours EECP,and 3-month after attack.Then contrast the difference of these indicators.Result Compare with the control group,after EECP treatment and after 3-month attack,the scores of NIHSS were statistically significant,(after EECP:44.1％ vs 31.5％;after 3-month attack:55.6％ vs 40.5％),(P＜ 0.05).Compare with the control group,after 3-month attack,the score of mRS in EECP group was declined statistically significant,and the rate of favourable prognosis rise obviously (P＜0.05).Conclusion EECP can effectively improve neurological function and promote health and improve prognosis in the patients with acute cerebral ischemic stroke.
ABSTRACT
Objective To assess the predictive value of endoscopic ultrasonography(EUS)for esophageal varices(EV)bleeding by studying the relationship between esophageal collateral veins(ECV), portal vein(PV)trunk with its main branches and EV bleeding. Methods A retrospective cohort study of 114 cases of moderate and severe EV was conducted. The ECV level was determined through EUS. At the same time,diameters of PV,azygos vein(AIV)and spleen vein(SV)were measured through EUS. The predictive value of ECV level and diameters of PV, AIV, SV for EV bleeding were assessed during the 1-year follow-up, which started from the first EUS examination to EV bleeding or the end of follow-up. Results Single factor Cox regression analysis showed severe peri-ECV varices had higher risk than mild in EV bleeding(HR=4.081,95%CI:1.833-9.086,P=0.001); severe para-ECV varices had higher risk than mild in EV bleeding(HR= 4.042, 95%CI:1.814-9.005,P= 0.001). Multivariable Cox retrospective analysis showed ECV level was an effective predictor for EV bleeding, when the peri-ECV and para-ECV were severe varices, EV bleeding risk increased to 3.831 3(P=0.004 3)and 3.493 3(P=0.003 1) times compared with mild respectively. Diameters of PV,AIV and SV could predict EV bleeding(PV AUC=0.959,P<0.001;AIV AUC=0.958,P<0.001;SV AUC=0.830,P<0.001).In addition, when diameter of PV>13.65 mm(sensitivity=0.94, specificity=0.84), AIV>8.65 mm(sensitivity=0.94, specificity=0.89),SV>9.45 mm(sensitivity=0.90, specificity=0.67), EV bleeding risk increased significantly. Conclusion EUS is helpful to predict the risk of moderate and severe EV bleeding, and severe varices of ECV,PV,AIV,and SV can be used as indicators to predict risk of EV bleeding.
ABSTRACT
Objective To investigate the expression of vascular endothelial factor C(VEGF-C) and E-cadherin in gastric cancer and explore the relationship between expression of VEGF-C and E-cadherin and the pathogenesis of gastric cancer.Methods Real-time quantitative reverse ranscriptase-polymerase chain rection was applied on 40 cases of gastric cancer and corresponding adjacent noncancerous tissues,in order to detect mRNA expression of VEGF-C and E-cadherin gene.VEGF-C and E-cadherin protein expression in gastric cancer and adjacent normal gastric mucosa were detected by immunohistochemistry.Statistical analysis was carried out to analyze the correlation among VEGF-C,E-cadherin and protein expression with various clinical parameters in these gastric cancer patients.Results The expression of VEGF-C protein in 40 cases of gastric cancer's cancer tissues was 0.461±0.012,significantly higher than that in the adjacent normal tissues(0.036+0.023;t=1.101,P＜0.05),but E-cadherin expression was significantly lower than that of the adjacent normal tissues (0.079±0.002 vs.0.321±0.005;t=1.844,P＜0.05).There was correlation between VEGF-C mRNA expression with histological grading,TNM staging,lymph node and distant metastasis (t=-1.621,-1.474,-2.378,-1.966,P＜0.05).There was correlation between E-cadherin mRNA expression with tumor size,histological grading,TNM stage,there was a significant difference (t=1.875,1.673,1.544,P＜0.05).VEGF-C and E-cadherin protein expression was negatively correlated(r=-0.688,P＜0.05).Conclusion Up-regulated of VEGF-C gene and decreased expression of E-cadherin may play an important role in the carcinogenesis of gastric cancer
ABSTRACT
Objective To explore the association between PI3K polymorphisms in insulin signal transduction pathway and Alzheimer's disease (AD)risk.Methods There were three groups,including 112 cases for AD +T2D group,231 cases for only AD group,and 231 cases for healthy controls group.The polymorphisms in PI3K gene was sequenced by PCR and the concentration of PI3K in serum was tested by enzyme -linked immunosorbent assay (ELISA).Results Overall,there was significantly statistical difference in PI3K rs3730087 polymorphism among three groups (χ2 =20.99,P =0.000 3).The CC frequency of PI3K rs3730087 polymorphism in AD with T2D group and AD control group was significantly higher than that in the healthy control group.The PI3K protein level of differ-ent genotype was statistically significant (F =27.450,P <0.000 1).As for CC genotypes of PI3K rs3730087 poly-morphism,the PI3K protein level was statistically different among these three groups (F =8.096,P =0.000 6).Moreover,the PI3K protein level of the three groups was different (F =9.034,P =0.000 1),which in both AD group was lower as compared with healthy control group.Conclusion The study suggested that CC genotype of PI3K rs3730087 polymorphism in insulin signaling transduction pathway might be a risk factor for AD with T2D and it also affects the expression level of PI3K protein.However,the polymorphism is not shown to be exclusive in AD patients with T2D.
ABSTRACT
Objectives To explore the effects of enhanced external counterpulsation(EECP)on the serum level of C-reactive protein and endothelin-1 in patients with cerebral ischemic stroke,to provide clinical evidence for the treat?ment and secondary prevention of patients with cerebral ischemic stroke. Methods Total 187 patients with ischemic stroke were enrolled measure the serum level of C-reactive protein and endothelin-1, before EECP, after36 hours EECP, and one-month after EECP. Then contrast the difference of these indicators. Result After treatment, the serum levels of C-reactive protein and endothelin-1 in EECP group were obviously decrease and the difference was statistically signifi?cant(hs-CRP 60.1%vs. ET-1 40.9%,P0.05). Conclusion EECP can obvi?ously reduce the serum levels of C-reactive protein and endothelin-1 in the patients with ischemic stroke, which indi?cates that EECP can slow atherosclerotic process.
ABSTRACT
Objective To discuss the artery effects of enhanced external counterpulsation for the progressive stroke patients.Methods Ninety-two progressive stroke patients who were treated in the Fourth People's Hospital of Shenzhen from August 2010 to February 2015 were selected and equally divided into the treatment group and the control group based on the random number table.The control group were received conventional therapy,and the treatment group were added treated with enhanced extemal counterpulsation therapy.Results All patients were successfully completed treatment,the C-reactive protein (CRP) and Endothelin-1 (ET-1) were presented decreased significantly after treatment (P＜ 0.05),and the C RP and ET-1 values in the treatment group were (2.09±2.11) mg/L,(13.98±6.30) mg/L,significantly lower than those of the control group((8.12±2.46) mg/L,(46.09± 11.02) mg/L;t =15.309,14.985;P＜0.05).After treatment,the FMD and NMD values in the treatment group were significantly increased from (5.26±1.34)％ to (11.93 ±2.13) ％,and from (13.20±5.33)％ to (22.98±8.34)％,in the control groupand were from (5.27±1.33)％ to (8.10±1.43) ％,and from (13.67±4.10)％ to (16.09±5.12)％ (t=16.934,21.787,8.443,12.345;P ＜0.05),and the value of FMD and NMD in treatment group were significantly higher than in the control group(t =7.982,9.113;P ＜ 0.05).The cardio ankle vascular index (CAVI) and brachial ankle pulse wave velocity (baPWV) values in the treatment group were significantly reduced after treatment,the difference was significant (P＜0.05),and compared with the control group the difference was also statistically significant (t =4.281,8.456;P＜ 0.05).Conclusion Enhanced external counterpulsation for the progressive stroke patients can effectively inhibit the expression of endothelin and inflammatory factors,improve endothelium-dependent relaxation of blood vessels,improve arterial elasticity,and thus play more effective treatment.
ABSTRACT
Objective CD4 +IL-17 +cells are a group of newly discovered effector CD4 +T cells, which may play a key role in the pathogenesis of cancer.This study aims to investigate the expres-sion of CD4 +IL-17 +cells in pancreatic cancer and its correlation with the clinicopathological characteristics and prognosis of the dis-ease as well as the clinical significance of the cells in the microenvironment of pancreatic cancer. Methods We collected tumor tis-sue and tumor-adjacent normal tissue samples from 51 pancreatic cancer patients.We determined the expressions of CD34 and vascular endothelial growth factor ( VEGF) and measured the proportion of IL-17 +cells in the cancer tissue using immunohistochemistry and the fluorescence activated cell sorter, respectively, followed by analysis of their correlation with tumor angiogenesis, clinicopathological pa-rameters, and survival time of the patients. Results The percentage of CD4 +IL-17 +cells in tumor tissue was positively correlated with microvessel density (r =0.534, P0.05).Fifty (98.0%) of the patients were successfully followed up for 2-67 months, which revealed a median survival time of 16.6 ±4.8 months, significantly longer in those with a higher expression of intratumoral IL-17 +cells (P<0.05).Univariate analysis showed an association of the survival rate with the tumor size, TNM stage, lymph node metastasis, and level of intratumoral IL-17 +cells, while multivariate analysis showed the TNM stage to be an independent prognostic factor for the survival of the pancreatic cancer patients. Conclusion The expression of CD4 +IL-17 +cells in the tumor tissue is positively correlated with tumor angiogenesis, while that of IL-17 +cells with the clinicopathological parameters and survival time of the patients and therefore may serve as an important immune indicator for the prognosis of pancreatic cancer.
ABSTRACT
Objectives To examine the effects of enhanced external counterpulsation on arterial elasticity in stroke patients to provide clinical evidence for secondary prevention of patients with cerebral ischemic stroke. Methods Total 192 patients with ischemic stroke were enrolled and then divided into the EECP (n=107) and control (n=85) group. Auto-matic measurement synchronous atherosclerosis detector was use to measure brachial-ankle pulse wave velocity (BaP-WV) and cardio-ankle vascular index (CAVI). The difference of BaPWV and CAVI were evaluated before, at 36 hours and one month after EECP. Results The BaPWV and CAVI significantly decreased at 36 hours and 1 month after treat-ment in EECP groups compared to either pre-therapy or control groups (all P<0.05). Conclusions EECP can signifi-cantly reduce the BaPWV and CAVI and improve the arterial elasticity in patients with cerebral ischemic stroke. Thus, arterial elasticity may be an important index to evaluate the effects of EECP on cerebral ischemic stroke.
ABSTRACT
Objective To investigate the immunological pathogenesis of immune reconstitution inflammatory syndrome (IRIS) during highly active antiretroviral therapy( HAART), in this prospective cohort study we analyzed the lymphocyte subsets, lymphocyte activation, changes in regulatory T cells, and levels of Th1 and Th2 cytokines in both IRIS and non-IRIS groups. Methods Two hundred and thirty-eight AIDS patients received HAART and participated prospective research cohort for 24 weeks follow-up. Forty-seven IRIS cases and 191 non-IRIS cases were enrolled in the IRIS group or non-IRIS group respectively. Blood samples were collected in both groups at pre- and post-HAART 12 weeks, 24 weeks. Using flow cytometer to detect the immunophenotypes of lymphocyte subsets (CD4 + CD45RA+ CD62L+, CD8+ CD45RA+ CD62L+naive T cells; CD4+ CD45RO+, CD8+ CD45RO+ memory T cells), activated T lymphocytes (CD4+CD38 +, CD8 + CD38 + cells), and regulatory T cell ( CD4 + CD25 + Foxp3 + ). Blood samples collected at pre-and post-HAART4 weeks, 12 weeks, 24 weeks and used ELISA to detect IL-2, IFN-γ, IL-4, IL-10and IL-7 cytokine serum levels. Results The percentages of CD4 + and CD8 + naive T cells and mlemory T cells exhibited no significant differences at the baseline, 12 weeks, 24 weeks of HAART initiation between both groups, but CD4 + and CD8 + memory T cells were demonstrated a trend towards to increase while compared to baseline during HAART. The percentages of CD4 + and CD8 + activated T cells are significantly higher at the baseline while compared to normal control and demonstrated a downward trend, but between both groups showed no significant difference. The percentages of CD4 + regulatory T cell was lower in IRIS group than non-IRIS group at the baseline, 12 weeks, 24 weeks and the onset of IRIS. Th1 cytokines, IL-2 and IFN-γshowed an upward trend during HAART at the levels of IRIS group had significantly increased at 4 weeks and the onset of IRIS. Th2 cytokines, IL-4 and IL-10 showed a downward trend during HAART,and the levels of IL-10 in IRIS group had significantly decreased at 4 weeks and the onset of IRIS. IL-7 was higher than normal control at the baseline in two groups and showed a downward trend during HAART. The level of IL-7 was higher than non-IRIS group at all follow-up points. Conclusion Memory T cells appear rapid increase in the early stage of HAART and may play a significant role in the inflammatory response of IRIS. CD4 + and CD8 + naive T cells, memory T cells and activated T cells showed no significant difference between IRIS and non-IRIS group within 24 weeks after HAART started. There was a significant reduction in the frequency of regulatory T cells in IRIS group without obvious upward trend during HAART, suggesting that the immune suppression function of regulatory T cells in IRIS was impaired. IL-2 and IFN-γ significantly increased while IL-10 significantly decreased at 4 weeks post-HAART initiation and onset of IRIS in IRISgroup than non-IRIS group, suggested that IRIS was related to cytokines environment disorder. That is, a significant increase in inflammatory cytokines, while the relative lack of non-inflammatory cytokines. The level of IL-7 decreased gradually after HAART started, and it was higher in IRIS group when compared to non-IRIS group in the first 24 weeks after HAART started. Also IL-7 may play a role in the pathogenesis of IRIS.
ABSTRACT
Objective To determine the incidence, clinical manifestation and risk factors of immune reconstitution inflammatory syndromes (IRIS) in highly active antirctroviral therapy (HAART) for HIV/AIDS patients. Methods Two hundred and twelve HIV/AIDS patients received HAART, and were followed up for 6 months. The incidence time and disease spectrum of IRIS were observed. Multiple logistic regression analysis was performed to identify the risk factors for IRIS. Results Among 212 patients, there were 59 (27.8%) experienced an IRIS event during the first 6 months of HAART, 2 of which died (2/59,3.39% ). Median time of IRIS onset was 21 days form HAART initiation. The disease spectrum included tuberculosis, herpes virus infections, pneumocystis jirovecii pneumonia, cryptococcal meningitis and penicillium marneffei infection. Risk factors of IRIS included baseline infections ( OR = 1. 655, P =0.010),fever during HAART ( OR = 2. 344, P= 0.006), and baseline CD4 + count ( OR = 1. 556, P = 0. 034).Conclusions IRIS usually occurred within the first month from HAART initiation, and tuberculosis and herpes virus infection are most common. The occurrence of IRIS is associated with the antigens burden and the decreased baseline CD4 + count.
ABSTRACT
Objective To determine the incidence, clinical manifestation and part of lymphokines which represent the balance of Th1 and Th2 in the role of the immunologic mechanisms for IRIS(immune restoration inflammatory syndromes)in patients initiating HAART(Highly Active Antiretroviral Therapy).Methods A prospective study of all patients initiating HAART was performed. A period of six months tracking initiating HAART was performed. The incidence of IRIS, time of occurrence and clinical disease spectrum were recorded. The main T lymphokines including IL-2, INF-γ, IL-4, IL-10 which on behalf of the balance of Th1 and Th2 were detected. To explore the immunopathologic mechanisms for IRIS, the levels of T lymphokines at pre-HAART, initiating HAART for 1 month, 3months and 6 months were compared in IRIS group and non-IRIS group, healthy group. Results A total of 212 patients were enrolled in this study. 59 patients were diagnosed as IRIS at a median of 21 days after HAART initiation (QR 19 days).The main disease spectrum included tuberculosis, herpes virus infections, pneumocystis jirovecii pneumonia. No matter in the IRIS group or non-IRIS group, the main lymphokines baseline of IL-2, INF-γ reduced and IL-4, IL-10 increased before HAART compared to healthy group (P ＜ 0. 05), which had the tendency to restore balance relations initiating HAART. The lymphokines levels had significant difference between baseline and 6 months initiating HAART (P ＜ 0. 05). The changed levels of lymphokines between IRIS group and non-IRIS group before HAART had significant difference compared to healthy group. IL-2, INF-γ increased level[(11.68 ± 2. 89) pg/ml vs (8.52 ±2.26) pg/ml; (22. 19 ± 6. 22) pg/ml vs (18.34 ±5. 35) pg/ml] and IL-10 decreased level [(19. 21 ± 4. 03) pg/ml vs (23. 19 ± 5.92) pg/ml] had significant difference between IRIS group and non-IRIS group initiating HAART I month(P ＜0. 05). Conclusions The incidence of IRIS during 6 months initiating HAART in HIV/AIDS was 27. 8%, IRIS usually occurred in 1 month initiating HAART. The most common disease spectrum was infectious disease, including tuberculosis and herpes virus infection. Lymphokine of Th1 and Th2 existed unbalance in IRIS group and non-IRIS group before HAART. The unbalance tendency in IRIS group was more obvious. All lymphokines had the trend to recover balance. IL-2, INF-γ significantly increased and IL-10 significantly decreased, which might involve the occurrence of the IRIS.
