Objective To evaluate the role of plasma IL-37 levels in patients with acute coronary syndrome (ACS). Methods Plasma biomarkers IL-37, CRP and NT-proBNP levels were measured in 40 patients with stable angina pectoris (SA group), 65 patients with unstable angina pectoris (UA group), 47 patients with acute myocardial infarction (AMI group) and 60 control patients. Results The plasma IL-37, CRP and NT-proBNP levels were significantly increased in patients with ACS patients. A correlation analysis showed that the plasma IL-37 levels were positively correlated with the levels of CRP and NT-proBNP, and negatively correlated with LVEF. Conclusions The results indicated that the plasma IL-37 levels are associated with the onset of ACS symptoms.

Objective: To study the dynamic changes of type Th22 cell immunological response during atherosclerosis process in experimental mice in order to provide a new theoretical basis for atherosclerosis therapy. Methods: 8 weeks C57BL/6J mice were divided into 2 groups: Experiment group,n=24 ApoE-/- mice and Control group, n=24 normal mice. All animals received high fat diet and the following indexes were compared between 2 groups at 0, 4, 8, 12 weeks after treatment: aortic atherosclerotic lesions were deifned by Oil red O staining, dynamic changes of Th22 cells in spleen were measured by lfow cytometry, mRNA expressions of interleukin-22 (IL-22), IL-22R1, AhR and T-bet in aorta were examined by RT-PCR, blood levels of IL-22 was detected by ELISA. Results: Compared with Control group, Experiment group had the increased area of aortic atherosclerosis (the ratio of plaque area/lumen area) and Th22 cell (CD4+ IL-22+/CD4+T cell) amount, elevated mRNA expressions of IL-22, IL-22R1, AHR, T-bet in aorta and higher blood levels of IL-22 at all time points, the differences between each time point (except 0 week) had the statistic meaning,P<0.05. In Experiment group, the differences between 2 adjacent time points, for the area of aortic atherosclerosis and mRNA expressions of AHR, T-bet: 4 weeks vs 0 week, 8 weeks vs 4 weeks, 12 weeks vs 8 weeks all had statistic meaning; for Th22 cell amount: 4 weeks vs 0 week, 8 weeks vs 4 weeks had statistic meaning and 12 weeks vs 8 weeks had no real distinction; for mRNA expressions of IL-22, IL-22R1 and blood levels of IL-22: 4 weeks vs 0 week had statistic meaning and 8 weeks vs 4 weeks, 12 weeks vs 8 weeks had no real distinctions. Conclusion: Hyperactive immunological response of Th22 cells might be involved in atherosclerosis process, the relevant mechanism should be further studied.

This study is to observe the effect of gross saponins of Tribulus terrestris (GSTT) on protein kinase Cepsilon (PKCepsilon) and apoptosis-associated protein in the apoptosis of cultured cardiocyte apoptosis induced by hydrogen peroxide (H2O2), and to explore the mechanisms of GSTT against myocardial apoptosis. Primary cardiocytes were isolated and cultured. Myocardial apoptosis was induced by H2O2 and analyzed with flow cytometry. Protein content of phospho-PKCepsilon, Bcl-2, and Bax were detected with Western blotting analysis. Cleaved caspase-3 protein content was determined with immunocytochemical technique. After the pretreatment of 100 mg x L(-1) GSTT, compared with H2O2 group, GSTT could not only decrease the apoptotic percentage in cardiocytes damaged by H2O2 (P < 0.01), but also reduce protein contents of Bax and cleaved caspase-3 (P < 0.01), and increase protein content of phospho-PKCepsilon and Bcl-2 significantly (P < 0.01). PKC inhibitor chelerythrine (Che) could prevent partly the effect of GSTT against myocardial apoptosis (P < 0.05 and P < 0.01). Mechanisms of GSTT against myocardial apoptosis might be associated with inhibition of mitochondrial apoptosis pathway after PKCepsilon activation.

Objective To investigate the feasibility of spin-echo echo-planar imaging(SE-EPI) of magnetic resonance elastography (MRE) for the diagnosis of pancreatic mass and to evaluate the difference of stiffness value in different pancreatic mass. Methods In a retrospective study, MRE was performed in 20 healthy volunteer (control group) and 62 patients with surgery-proved pancreatic masses, including pancreatic cystadenoma in 5 cases and solid masses of pancreas in 57 cases (39 with malignant mass and 18 with benign mass) using 3.0 T MRE. The differences of stiffness between two groups were evaluated using non-parametric Mann-Whitney U test. ROC was used to assess the diagnostic ability of elastogram for the detection of pancreatic masses, and to evaluate MRE-determined stiffness for the differentiation of masses from healthy pancreas, and malignancy from benign solid masses. Results The total detection rate of elastogram was 91.9%(57/62),with false positive rate of 5.0%(1/20) and false negative rate of 8.1%(5/62). The median stiffness value in the control group vs patient group were 1.18 kPa (interquantile range:1.15 to 1.30) kPa and 2.43 kPa (interquantile range:1.94 to 3.64 kPa) respectively, with statistically significant differences (Z=-5.967,P<0.01). The sensitivity and specificity of stiffness (≥1.36 kPa) to differentiate pancreatic mass from healthy pancreas was 93.6%and 100.0%, respectively, and to differentiate benign and malignant solid masses (≥2.17 kPa) was 82.1%and 83.3%, respectively. Conclusion MRE is a promising method in detecting and distinguishing different pancreatic masses.

OBJECTIVE: To prepare gynecological Jiekang lotion and to establish its quality standard. METHODS: The Caffeotannic acid in Flos Lonicerae, the Berberine in Cortex Phellodendri and the Ammothamnine in Radix Sophorae Flavescentis were identified by TLC; HPLC was adopted to determine the content of Osthole with Hypersil DOS C18 as chromatograpic column. The mobile phase consisted of acetonitrile-water (54∶46) with a flow rate of 1.1mL? min-1. The detection wavelength was set at 321nm. RESULTS: Both the chief components in Jiekang lotion and the corresponding reference substances showed the identical discrimination reactions. The linear range of Osthole was 13～130?g?mL-1. CONCLUSION: The method is sensitive in qualitative reaction, specific in TLC identification, accurate in HPLC quantitation and recurrent. The established standard is applicable for the quality control of Jeikang lotion.

Objective To study the expression of inflammatory factors in the saliva and the stability of implants after implant denture repair in pa-tients with dysplasia of the dentition defect ,and to analyze the prognosis of patients with lipid metabolic disorder. Methods The dentition defect patients with lipid metabolism disorder were selected as the experimental group. Patients with lipid defect were selected as the control group. Saliva was collected before implantation,1 month and 3 months after implantation. ELISA method was used to detect IL-6,IL-1βand TNF-α. Osstell ISQTM radio frequency analyzer was used to detect the stability of the implants and the periodontal status was detected by Florida probe. Re-sults There were no significant differences in the depth of implant probing(PD),bleeding index(BI)and ISQ between the two groups by radio frequency analyzer(all P>0.05). The levels of IL-6,IL-1βand TNF-αin the pre-implantation,1 month and 3 months after implantation were sig-nificantly higher than those in the control group(all P<0.05). The levels of IL-6,IL-1βand TNF-αin the experimental group were significantly higher than those in the control group before planting(all P<0.05) 3 months after planting,there were no significant differences of IL-6,IL-1β, and TNF-αbetween the experimental group and control group(all P>0.05). Conclusion The patients with dyslipidemia after implantation have good implant stability as those with normal blood lipid ,and the patients with dyslipidemia can also obtain good prognosis.

ObjectiveTo share the experience of arterial plasty and reconstruction of variant arteries in living donor liver transplantation. MethodsFrom September 2006 to May 2010, 73 living donor liver grafts (64 cases using the right lobe,9 cases using left lobe) were used in patients with end-stage liver disease. The hepatic arteries were evaluated preoperatively with computed tomography and magnetic resonance angiography. Back-table arterial plasty was performed under a microscope or a loupe according to arterial variation. We described technical points based on anatomic variations. There were 13 (17. 8 ％) liver grafts with anatomic hepatic arterial variations and all of these cases were subjected to back-table reconstruction with interrupted 8-0 or 9-0 nonabsorbable nylon monofilament sutures according to the diameter of artery. ResultsIn 3 cases, the associate right hepatic arteries that were arisen from superior esenteric arteris (SMA) were reconstructed to cystic arteries. In 2 cases with the associate right hepatic arteries arisen from the abdominal trunk, the right hepatic arteries and associate right hepatic arteries of donors were anastomosed with right hepatic arteries and left hepatic arteries in recipients respectively. In 2 donors, hepatic arteries had branches, which were reconstructed. All of the arterial plasty were conducted on a back table. No arterial thrombosis was found during a postoperative follow-up period of 6 months. ConclusionLive donor liver transplantation using the right lobe with hepatic artery variation can be performed safely, but there is a potential operative risk of severe complication after transplantation. Tominimize operative difficulties and complications, back-table reconstruction should be applied and proper treatment is given according to individual situations to ensure a safe and satisfactory outcome

Objective To explore the clinical value and safety of early enteral nutrition support in patients after liver transplantation.Methods We retrospectively analyzed the clinical data of 86 cases who used early enteral nutrition support therapy after liver transplantation between January 2008and October 2011.All of patients were uproot the gastric tube at the first day after the operation,and gradual to the normal diet.The patients who used parenteral nutrition support therapy were as the control group(n＝112).Then we compared the data of patients in the two groups.Results The early enteral nutrition is more useful to the patients after liver transplantation than intravenous nutrition [In the seventh day after the operation,the control group's ALT was (45.2 ± 12.9) U/L,AST was (40.2±9.4) U/L,ALBwas (35.6±2.5) g/L,P＜0.05].The early enteral nutrition also can decrease hospital stay and hospital costs [(14.2±3.4) d,P＜0.05].Conclusion The early enteral nutrition is useful and safe to the patients after liver transplantation.
