Objective To investigate the changes of serum soluble Fas (sFas) and soluble Fas-ligand (sFasL), and the relationship betweenthe level of serum sFas or sFasL and the infarct volume in patients with acute cerebral infarction (ACI). Methods Sixty patients with ACI (female 28, male 32) served as study group and 30 healthy subjects (female 18, male 12) served as control group. An enzyme-linked immunosorbent assay was used to detect the levels of serum sFas and sFasL in both groups, and the differences of the sFas and sFasL concentration were compared between the two groups. Results The levels of serum sFas at 48 hours, at day 7 and 14 in the ACl group were 6. 27 ± 1.48 ng/L, 4. 99 ± 1.15 ng/L, and 3.74 ± 0.58 ng/L,respectively, and they were all significantly higher than 3.00 ± 0. 38 ng/L in the control group (P <0. 05). The levels of serum sFasL at 48 hours, at day 7 and 14 in the ACI group were 4.40 ± 1.32 ng/L, 3. 19 ± 0.94 ng/L, and 1.91±0.45 ng/L, respectively. They were significantly higher than 1.15 ±0.21 ng/L in the control group (P<0.01). The levels of sFas (1.91 ± 0.45) ng/L, respectively, and they were all significantly higher than (4.98 ±0.91) ng/L(t = 12.12 ,P <0. 01)and (3.58 ±0. 87) ng/L(t =5.35 ,P <0.01) in the small infarction group. The levels of serum sFas and sFasL in patients with ACI showed positive correlation (r =0. 748, P =0. 01). Conclusions High serum sFas and sFasL may indicate larger infarct volume in patients with ACI.

Objective: To observe and analyze the efficacy and safety of naloxone in the treatment of patients with pulmonary encephalopathy. Methods:50 patients with pulmonary encephalopathy were randomly divided into the observation group and the con-trol group. All the patients were carried out continuous oxygen with non-invasive ventilator. The control group was treated with the con-ventional treatment, and the observation group was given naloxone on the basis of conventinal treatment. The treatment course was 7 days. The clinical efficacy, clinical indicators and adverse events of the two groups were observed. Results:The total effective rate of the observation group reached 92. 00%, which was higher than that of the control group without statistical significance (72. 00%, P>0. 05). The levels of pH, PaO2, PaCO2, angiotensinⅡand IL-8 were significantly improved in both groups after the treatment (P<0. 05), and the improvement in the observation group was much better than that in the control group (P<0. 05). The incidence of ad-verse reactions of the two groups after the treatment showed no significant difference (P>0. 05). Conclusion: Early application of naloxone in the treatment of pulmonary encephalopathy can improve the clinical indices significantly with low incidence of adverse reac-tions and high safety, which is worthy of promoted use in clinics.

Objective To investigate the blood transfusion paths in elderly patients in order to ensure the blood transfusion safety in the elderly.Methods Clinical data of elderly patients (aged 60 and over) receiving blood transfusion were selected from January 2008 to December 2013.Data of blood transfusion in different clinical department were analyzed.Results From 2008 to 2013,the number of elderly patients receiving blood transfusion and transfusion volume showed the rising trends.Patients in Department of Cardiothoracic Surgery had the most blood transfusion volume among all surgical departments (9.3U/person),and plasma transfusion accounted for the most with plasma and red blood cells in a 3 ∶ 1 ratio.Patients in Department of Internal Medicine had the most blood transfusion volume among all non surgical departments (15.9U/person),and platelets transfusion accounted for the most with platelets and red blood cells in a 3 ∶ 1 ratio.The oldest patients on average receiving blood transfusion in the top 10 was from Department of Emergency (aged 77 years),and the most common cause was gastrointestinal hemorrhage.The youngest patients receiving blood transfusion in the top 10 was from Department of Cardiothoracic Surgery and Department of Gynecology (aged 69 years),and the most common cause was huge pleural mass and ovarian cancer.Conclusions Blood transfusion for elderly patients should be restrict the indications for transfusion strictly,choose the reasonable transfusion time,blood components and volume.Physiological and functional changes and clinical features of elderly patients should be paid attention to at the same time in order to reduce unnecessary transfusions,particularly the dependence on plasma transfusion and unnecessary collocated blood transfusion,to avoid the overload and adverse transfusion reactions.

Objective To investigate the protective effect of sodium tanshinone ⅡA sulfonate(STS) on adriamycin-induced H9c2 cell apoptosis. Methods H9c2 cells were divided into four groups: the control group, the ADR group, the STS group, and the AS(ADR+STS) group. MTT assay were used to detect cell proliferation and cell death. The cell cycle of H9c2 cells were determined by flow cytometry assay. Protein expression of Bcl-2, Bax and Caspase-3 was detected by Western blot assay. Results Compared with the control group, cell proliferation was significantly reduced , and the number of the cells was significantly increased in the G0/G1 phase in the ADR group(P < 0.01, P < 0.05). At the same time, the expression of Caspase-3 was dramatically enhanced and the ratio of Bcl-2/Bax was significantly reduced (P < 0.05, P < 0.01) in the ADR group. However, pretreatment of STS increased H9c2 cell proliferation, decreased the number of the arresting cells, inhibited the expression of Caspase-3, and improved the ratio of Bcl-2/Bax (P < 0.05, respectively). Conclusions STS can attenuate ADR-induced myocardial cell apoptosis.

Medicinal plants of the Fructus Amomi containing three species (A momum villosum, A momum longiligu-lare, Amomum villosum var. xanthioides)are well-known, which are widely used as traditional medicines. The mor-phological characteristics of the three origins are very similar, especially in the form of seed. In this study, 60 sam-ples of Fructus Amomi were co llected, and 34 sequences of the Fructus Amomi and their adulterants from GenBank were analyzed. Single nucleotide polymorphisms (SNPs) were detected. All the ITS2 sequences here (including our ex-periments and GenBank data)were examined for SNPs at the interspecies level. Results from the study revealed that two stable bases at position 135 bp and 199 bp were found, which could be used as a unique marker to distinguish the three origins of Fructus Amomi. The two SNPs in the ITS2 were found to exist stably between the three species, and all the GenBank sequences of the Fructus Amomi. Our findings indicated that SNP-based DNA barcoding could be used as an efficient method for the rapid and accurate identification of the three origins of Fructus Amomi.

Objectives To investigate the prevalence of left ventricular hypertrophy (LVH) and risk factors in children with chronic kidney disease (CKD). Methods The biochemical indices, blood pressure and left ventricular mass index (LVMI) in pa-tients with CKD were retrospectively analyzed. The risk factors of LVH were analyzed using Logistic regression. Results In 125 CKD patients, 32.00%were at 4th stage and 68.00%were at 5th stage. The estimate glomerular ifltration rate (eGFR) and hemo-globin (Hb) level were signiifcantly higher in CKD patients at 4th stage than in those at 5th stage. The intact parathyroid hormone (iPTH), serum phosphorus and LVMI were signiifcantly lower in CKD patients at 4th stage than in those at 5th stage (P<0.01). LVH was detected in 33.60%CKD patients. The eGFR and Hb level were signiifcantly lower in CKD patients with LVH than in those without LVH. The iPTH, serum phosphorus, systolic blood pressure and diastolic blood pressure were signiifcantly higher in CKD patients with LVH than in those without LVH (P<0.05). Logistic regression analysis indicated that only hypertension, hyperphosphatemia, moderate and severe anemia were the risk factors of LVH. Conclusion Control of hypertension, hyperphos-phatemia and anemia is the key to prevent LVH in CKD patients.

Objective To investigate the application of PKH26 and molecular light imaging system in cartilage en?gineering. Methods Canine chondrocyte was labeled by fluorescent dye PKH26 and seeded into the porous cartilage acel?lular matrix scaffold. The cells/scaffold constructs were cultured in vitro for 1 week. Then the constructs were implanted into the dorsal pocket of nude mice. We utilized a molecular light imaging system to macroscopically observe cells/scaffold con?structs in vivo with fluorescence at the 4th weeks, and compared with X-rays taken at the same position. The fluorescence im?ages were compared with the immunohistochemical and immunofluorescent results of cartilage-like tissue in vivo. Results Luminescent images were acquired at the 4th weeks, a red color enhanced overlay of the luminescent image over X-ray photo?graphic image demonstrated the location of the implants and the cell viability and cell growth on porous CACM scaffold in vivo were very well. Histological results show that the safranin O, anti-collagenⅡimmunohistochemistry and toluidine blue stain of cartilage-like tissue is positive. Immunofluorescence examination demonstrated chondrocytes in the constructs whitch is showen red fluorescence, and anti-collagenⅡimmunofluorescent staining was showen in green while the overlap?ping image is showen in yellow. Conclusion This study outlines an applicable non-destructive method to evaluate cell growth in tissue engineering constructs in vivo using PKH26 and molecular light imaging system.

Objective To find an ideal method of DNA isolation from blood and especially from clotted blood and to minimize the volume of blood collected for laboratory and clinical tests.Methods DNAs were isolated from antiagglutinated and agglutinated blood samples from auricular veins of 30 healthy subjects. The DNAs of these samples were obtained by a nonenzymatic, nontoxic procedure optimized by us and determinated by agarose gel electrophoesis and PCR. Results The yields of DNA isolated from clotted blood and antiagglutinated blood were (40.2?8.86)mg DNA/L and (39.1?10.2)mg DNA/L, and purities were 1.87?0.11 and 1.92? 0.12. The DNAs that we isolated from all samples had high molecular weight and by PCR the dimorphism of ALU alleles of the 8th intron of t-PA was easy to be obtained, so they were complete and reliable. Conclusion This method is rapid, easy, efficient and nontoxic for isolation of DNA from clotted and fresh blood and meets requirements for clinical testing and molecular biology study.

ObjectiveTo compare detection rate of pulmonary nodules and the radiation doses of digital tomosynthesis (DTS) and MSCT chest scanning by using the anthropomorphic chest phantom which containsthermoluminescent dosimeters( TLD ) and simulated pulmonary nodules.Methods The radiation doses of DTS and MSCT scanning were measured by using the anthropomorphic chest phantom which contains 45 TLD and simulated pulmonary nodules.The radiation doses of najor organs were converted into effective dose ( ED ). Three radiologists of different clinical experiences independently reviewed and recorded the density,diameter and position of pulmonary nodules.The sensitivity of nodule detection by DTS and MSCT were compared by Fisher exact test and Chi-square test. The paired t test was conducted to analyze the dose levels of DTS and MSCT.ResultsThe sensitivity of detection nodule by DTS and MSCT were 66.7％ (30/45) and 91.1％ (41/45) respectively.Statistically significant difference between the two examinations existed ( x2 =8.073,P ＜ 0.05).The sensitivity of detection - 650 HU ground glass opacity pulmonary nodule by MSCT and DTS were 93.3％ (14/15) and 73.3％ (11/15) respectively.There was no significant difference between DTS and MSCT ( P ＞ 0.05 ).The sensitivity of detection - 800 HU ground glass opacity nodule and ground glass opacity nodule (d ＜ 8 mm) by DTS were 33.3％ (5/15) and 16.7％ (2/12) respectively,which were lower than those by CT[80.0％ (12/15) and 66.7％ (8/12)].The radiation doses of DTS for various organs in the chest were lower than those of CT. Statistical significant difference between DTS and MSCT existed ( lung t =19.69,thoracic vertebral t =30.01,heart t =16.33,liver t =5.06,breast t =9.43,thyroid gland t =8.05 ;P ＜ 0.05).The effective doses of the DTS and MSCT were 0.65 and 7.71 mSv respectively.ConclusionsThere is no difference between the DTS and MSCT in the detection rate of -650 HU ground glass opacity nodule.For detecting the ground glass opacity nodule ( - 800 HU) and ground glass opacity nodule (d ＜ 8 mm),MSCT is superior to DTS. However,the radiation dosage of DTS is 8.41％ of the MSCT scanning.
