ABSTRACT

Objective:To investigate the value of D-dimer, carbohydrate antigen 199 (CA199) and insulin-like growth factor binding protein 2 (IGFBP2) for postoperative monitoring and prediction of survival time in patients with resectable pancreatic cancer.Methods:The data of 119 patients with pancreatic cancer who were admitted to the First Hospital of Qinhuangdao from May 2010 to January 2014 were collected. Immunoturbidimetry was used to determine the level of D-dimer before surgery, at postoperative stable disease stage and disease progression stage; electrochemiluminescence was used to determine the level of CA199, and enzyme-linked immunosorbent assay (ELISA) was used to determine the serum IGFBP2 level. A total of 30 healthy people and 40 patients with pancreatic serous cystadenoma were treated as the controls. The correlations of the levels of preoperative D-dimer, CA199 and IGFBP2 with clinicopathological characteristics and survival time of patients with pancreatic cancer were analyzed.Results:The levels of preoperative D-dimer, CA199, IGFBP2 in patients with pancreatic cancer were higher than those in the both control group (all P < 0.01). The levels of serum D-dimer, CA199 and IGFBP2 after the progression of pancreatic cancer were higher than those at postoperative stable disease stage [1 496.0 ng/ml (590.0 ng/ml, 2 280.4 ng/ml) vs. 578.1 ng/ml (381.7 ng/ml, 671.5 ng/ml), 207.0 U/ml (54.5 U/ml, 736.5 U/ml) vs. 31.9 U/ml (14.1 U/ml, 44.0 U/ml), (435±107) ng/ml vs. (249±83) ng/ml, all P < 0.01]. There were no statistical differences in the proportion of pancreatic cancer patients stratified by different clinicopathological factors with the increased levels of D-dimer before operation (all P > 0.05). The proportion of the increased levels of CA199 and IGFBP2 in patients with lymph node metastasis was higher than that in patients without lymph node metastasis (both P < 0.05); there was no association of the increased levels of CA199 and IGFBP2 with other factors (all P > 0.05). The preoperative progression-free survival (PFS) time and overall survival (OS) time of pancreatic cancer patients with elevated D-dimer level was shorter than that for those with normal D-dimer level [(10.6±1.2) months vs. (20.4±2.4) months, (18.9±1.9) months vs. (29.2±2.6) months, both P < 0.01]. When the threshold value of CA199 was 37 U/ml, there was no correlation between CA199 and survival of pancreatic cancer patients (all P > 0.05); when the threshold value was 253.8 U/ml (median CA199 for the enrolled patients) and 1 000 U/ml, patients with elevated CA199 level had shorter OS time and PFS time compared with the patients with normal CA199 level [253.8 U/ml: (11.5±1.5) months vs. (21.0±2.6) months, (19.9±2.1) months vs. (29.0±2.7) months, both P < 0.01; 1 000 U/ml: (8.9±1.9) months vs. (19.1±1.9) months, (15.5±2.3) months vs. (28.0±2.0) months, both P < 0.01]. When the threshold value of IGFBP2 was 339.1 ng/ml, patients with elevated preoperative IGFBP2 level had shorter PFS time and OS time compared with the patients with normal IGFBP2 level [(10.8± 1.1) months vs. (21.1±2.6) months, (18.9±1.8) months vs. (30.3±2.8) months, both P < 0.01]. Cox multivariate analysis showed that preoperative D-dimer and IGFBP2 levels were independent factors affecting PFS and OS in patients with pancreatic cancer (D-dimer: HR = 0.561, 95% CI 0.336-0.936, P = 0.027; HR = 0.515, 95% CI 0.303-0.874, P = 0.014; IGFBP2: HR = 0.430, 95% CI 0.253-0.731, P = 0.002; HR = 0.361, 95% CI 0.202-0.644, P = 0.001). Conclusions:For patients with resectable pancreatic cancer, D-dimer, CA199 and IGFBP2 can be used for postoperative condition monitoring, and preoperative D-dimer and IGFBP2 can be used for survival time prediction.

ABSTRACT

Hepatorenal syndrome (HRS) is one of the most serious complications of end-stage liver disease. Type Ⅰ/Ⅱ HRS has a high short-term mortality rate and poor prognosis. The diagnostic criteria for HRS based on serum creatinine cannot keep up with the world, and early diagnosis is of great importance to the treatment and prognosis of HRS. This article introduces the value and clinical significance of seven biomarkers for renal injury in the early diagnosis, differential diagnosis, and prognostic evaluation of HRS. It is pointed out that neutrophil gelatinase-associated lipocalin, interleukin-18, and kidney injury molecule-1 may be the biomarkers for early identification of renal injury in patients with liver cirrhosis. A combination of multiple biological indicators, imaging examination, and interventional techniques might be a feasible method for early diagnosis of HRS in future.

ABSTRACT

Objective: To analyze the characteristics of the healthy state of TCM (Traditional Chinese Medicine) of female, and preliminarily constructs the model of TCM health status identification of female with menstrual cycle. Methods: The text of disease diagnosis and syndrome differentiation of menstrual-cycle-linked disorders from Guidelines for diagnosis and treatment of common disease of gynecology in Traditional Chinese Medicine was analyzed, and the symptoms related with viscera functions, the waxing and waning of qi and blood, and pathogenic properties were extracted. The questionnaires of diseases and syndrome elements differentiation of female by calculating the weight relationship between symptoms and health status were designed to estimate the interior state of waxing and waning of yin-yang by figuring out the different periods of menstrual, and in the last step, Constitution in Chinese medicine Questionnaire was used to identify the constitution. Through the above four identification methods, a comprehensive identification of the female's health status of TCM was formed. Results: Through the disease identification model, we distinguished the state of disease and yet disease. And through the syndrome elements differentiation model, we knew the viscera functions, the waxing and waning of qi-blood and yin-yang, and pathogenic properties. And by identifying the internal qi-blood and yin-yang status, we initially built the model that can identify health status of female integrally with the constitution. Conclusion:The model identification results can reflect the comprehensive health status of female in multiple dimensions. It can make a fine classification of women.s TCM health status. It can not only help to know the previous health status but also help to speculate the future health trend, which contributes to the formulation of personalized health interventions of follow-up.

ABSTRACT

Objective To observe the peripapillary choroidal thicknesses (pCT) and subfoveal choroidal thicknesses (SFCT) of nonarteritic anterior ischemic optic neuropathy (NAION). Methods Forty-four Chinese patients with unilateral NAION were recruited and compared with 60 eyes of 60 normal age and refractive-error matched control subjects. pCT and SFCT were measured by enhanced depth imaging optical coherence tomography. Choroidal thicknesses of eyes with NAION and unaffected fellow eyes were compared with normal controls. Choroidal thicknesses of NAION eyes with or without optic disc edema were also compared. The correlation between choroidal thickness and retinal nerve fiber layer (RNFL) thickness, logarithm of the minimum angle of resolution (logMAR) best-corrected visual acuity (BCVA), and the mean deviation (MD) of Humphrey static perimetry in NAION eyes were analyzed. Results The pCT at the nasal, nasal inferior and temporal inferior quadrants in NAION eyes with optic disc edema were significantly thicker than that of normal subjects (t=3.152, 3.166, 2.808; P<0.05). There was no significant difference in the choroidal thicknesses between the unaffected fellow eyes of NAION patients and normal eyes of healthy controls; or between the NAION eyes with resolved optic disc edema and normal eyes (P>0.05). No significant correlation between choroidal thickness (r=-0.220, -0.140, 0.110), SFCT (r=0.096, -0.148, -0.131) and logMAR BCVA, perimetry MD and RNFL was found in eyes affected by NAION (P>0.05). Conclusions The peripapillary choroidal thicknesses increase in some quadrants in NAION eyes with optic disc edema. However, the choroidal thickness of NAION eyes is the same in age and refractive error-matched normal subjects.

ABSTRACT

Objective To assess the diagnostic value of 18 F?FDG PET/CT imaging for primary pul?monary lymphoepithelioma?like carcinoma (LELC). Methods A total of 19 patients (10 males, 9 fe?males;average age 56.4 years) with suspected primary pulmonary LELC undergone whole?body 18F?FDG PET/CT and chest contrast CT scan were enrolled in this retrospective study. The SUVmax and uptake pat?terns of FDG, the histological types and the clinical stages were recorded. Image characteristics of contrast CT and FDG PET/CT were observed, and the diagnostic efficiency was calculated. Two?sample t test and one?way analysis of variance were used to analyze the results. Results The diagnostic sensitivity and spe?cificity of LELC were 12/13 and 4/6 for FDG PET/CT. The SUVmax of LELC lesions was significantly differ?ent from that of other lung malignant tumors or lung benign lesions (F=3.67, P<0?05). The lesion had longer diameter, lower CT density, higher SUVmax in stage Ⅳ patients, compared with that in stageⅠ-Ⅲpatients ( F=7.01, P<0.05) . The significant difference of SUVmax was found between lesions with ring up?take and lesions with other uptake types (3.94±0.67 vs 2.86±0.35; t=4.07, P<0?05). The SUVmax was higher in Schmincke tumors when compared with that in tumors of Regaud subtype ( 3. 61 ± 0. 71 vs 2. 76 ± 0?29; t=2.99, P<0.05) . Conclusion 18 F?FDG PET/CT could be an accurate method in differential diag?noses of primary pulmonary LELC.

ABSTRACT

The infection rate of human cytomegalovirus (CMV) in the general population in our country is very high.The latent virus often becomes activated when patients' immune status turned to immunocompromised,which will cause serious clinical consequences.Because the manifestations of cytomegalovirus infection are nonspecific,the diagnosis of cytomegalovirus infection mainly depends on the laboratory tests.This article will review laboratory diagnostic methods and clinical significance of CMV infection in immunosuppression patients.

ABSTRACT

Background Many methods of ocular hypertension modeling have been used before,but these models remain short-duration ocular hypertension only.A new method of elevating intraocular pressure in mice by anterior chamber injection of polystyrene microspheres was reported abroad.However,this model is rarely used in China.Objective This study was to evaluate the application value of anterior chamber injection of polystyrene microspheres to establish glaucoma model in mice.Methods Forty-two SPF adult female C57BL/6L mice were divided into three groups according to random number table.Polystyrene microspheres (2 μl) were injected into the anterior chamber monocularly in the microspheres group,and the equal amount of PBS was used in the same way in the PBS group.No intervene was performed in the normal control group.The eyes of mice were examined by slit lamp microscope,and the intraocular pressure (IOP) was measured with TonoLab rebound tomometer in a 3-day interval after injection.Ocular histological sections were prepared 2 and 4 weeks after injection,and the anterior chamber angle was examined under the optical microscope.Neurons retrograde labeling was performed by 4% fluorogold to calculate the survival number of retinal ganglion cells (RGCs) and the nerve fiber density was detected to assess the degree of RGCs and axon damage in retinal flat mounts,and the β-Ⅲ-tubulin-positive cells in the RGCs layer were examined by immnofluorescence method.The use and care of the animals complied with the instruction of Association for Research in Vision Ophthalmology (ARVO).Results IOP was significantly higher in the mice of the microspheres group than that in the normal control group or PBS group 2 and 4 weeks (all at P<0.05).In the microspheres group,IOP reached peak in 2 weeks after injection and was significantly higher than that of 4 weeks after injection ([29.67±2.34] mmHg versus[15.71±1.23] mmHg) (all at P<0.05).In 2 and 4 weeks after the anterior chamber injection of polystyrene,corneal edema was found under the slit lamp microscope,and under the optical microscope,microspheres accumulated at the anterior chamber angle.Additionally,in 2 and 4 weeks after injection,the number of survival RGCs was (4 542.82 ± 653.72)/mm2 and (3 623.12 ± 628.79)/mm2,respectively in the microspheres group,which showed significantly decrease in comparison with (6 979.33 ± 678.49)/mm2 and (6963.91 ±497.29)/mm2 in the normal control group (t =17.729,28.569,both at P<0.05) and (6 843.21 ±573.42)/mm2 and (6 937.53±465.24)/mm2in the PBS group (t =16.975,29.145,both at P<0.05).The number of RGCs was significantly less in the fourth week compared with second week after injection (t =6.951,P<0.05).The β-Ⅲ-tubulin positive RGCs were (4 576.36± 479.64)/mm2 and (3 712.90 ± 660.31)/mm2 in 2 and 4 weeks in the microspheres group,respectively,which were significantly decreased in comparison with (6 725.94 ± 619.42)/mm2 and (6 741.90±663.60)/mm2 of the normal control group (t =18.811,22.182,both at P < 0.05) or (6 757.85 ±463.59)/mm2 and (6 773.17± 471.35)/mm2 in the PBS group (t =18.953,22.605,both at P<0.05),and in the microspheres group,β-Ⅲ-tubulin positive cells in the fourth week were decreased than those in the second week after injection (t=7.253,P<0.05).The neural fiber density in the microspheres group in 2 and 4 weeks after injection was (193.08 ±32.75)/mm2 and (139.O0 ±38.24)/mm2,respectively,with a significant decline in comparison with (305.57±81.21)/mm2 and (297.46±52.60)/mm2(t=8.900,16.883,both at P<0.05) of the normal control group or (312.63±70.62)/mm2 and (269.37±61.63)/mm2 of the PBS group (t=7.731,15.959,both at P<0.05),and the neural fiber density was significantly lower in the fourth week than that in the second week after injection (t =7.442,P<0.05).Conclusions Single injection of polystyrene microspheres into the anterior chamber can induce chronic ocular hypertension in mouse,which leads to the progressive damage of RGCs and neural fibers.This animal model shows a similar chronic pathogenic process to human glaucomatous eye.

ABSTRACT

Objective To study factors used to predict 30-day mortality and favorable outcomes to intracerebral hemorrhage (ICH) in young adult subjects and to estimate the reliability of these predictors.Methods Data of 175 acute ICH patients selected from 201 patients admitted to our hospital from 2008 to 2011 were reviewed retrospectively.Patients were assessed with Glasgow Coma Scale (GCS) and National Institutes of Health Stroke Scale (NIHSS) and routine laboratory examinations after admission.Independent predictors of 30-day mortality or good outcome (modified Rankin score,0-2) were identified by stepwise logistic regression.Results There were 90 male and 85 female,and 142 survivals and 33 deaths.The modified Rankin score (mRS) of survival group was <6 and mRS =6 in death group,and mRS <3 in good outcome group and mRS > or =3 in poor outcome group.Independent factors for 30-day mortality were hypertension (P =0.023) or hyperglycemia (P =0.007),infra-tentorial ICH (P =0.000),large ICH volume (P =0.008),low Glasgow Coma Scale (GCS) scores (P =0.000),high white blood cell count (P =0.000),higher blood glucose level (P =0.039) and prothrombin time (PT) (P =0.001) after admission.Independent factors for 30-day good outcome were younger age (P =0.001),normal blood pressure (P=0.010) or absence of hyperglycemia (P=0.028),lower NIHSS scores (P=0.000),small ICH volume (P =0.000),low white blood cell (WBC) count (P =0.000),lower blood glucose level (P =0.012) or lower systolic blood pressure (SBP) level (P =0.000) at admission.The NIHSS score and GCS score were excellent predictors,while the SBP level,WBC count and ICH volume were fine predictors.Conclusions Overall prognostic factors should be integrated to get high reliabilities for predicting the outcomes of ICH in young people.
