In recent years,there has been increasing evidence that microcirculatory disturbance,including vasoconstriction,shunting,inad-equate perfusion,increased blood viscosity,and coagulation,is closely associated with the pathogenesis of acute pancreatitis (AP).These processes may be exacerbated by ischaemia-reperfusion injury and the generation of oxygen radicals.The anatomical features of pancreatic microcirculation,the pathophysiological mechanism of pancreatic microcirculation disturbance and related inflammatory mediators,and pro-gress in the treatment of microcirculatory disturbance in AP are reviewed.It is suggested that the pancreatic and systemic microcirculation may play a key role in the development and progression of AP.

Acute pancreatitis happens rapidly and leads to patient's condition changing swiftly.Acute pancreatitis may be complicated by acute lung injury (ALI) and acute respiratory distress syndrome (ARDS),or even multiple organ dysfunction syndrome,and the mortality rate has been high.The mechanism of acute pancreatitis with complications of ALI and ARDS is intricate.It involves the uncontrolled inflammatory response,the damage and apoptosis of cell,the role of trypsin,the imbalance of coagulation and fibrinolysis,etc.These respects interrelate with each other,forming a complex network.Further study of mechanism of acute pancreatitis complicated with ALI and ARDS will supply more new target for clinical diagnosis and treatment.

Novel method of enantioseparation of ofloxacin by capillary electrophoresis with capactively coupled contactless conductivity detection (C~4D) using binary chiral selectors,hydroxypropyl cyclodextrin and hydroxypropyl methyl cellulose ( HP-β-CD and HPMC) ,was developed. The enantiomers of ofloxacin were baseline separated with an uncoated fused-silica capillary(45 cm×50 m i. d. ,L_(effi) = 40 cm)under the optimum separate conditions, 20 mmol/L HAc +6 mmol/L NaAc + 12 mg/L HPMC +35 mmol/L HP-β-CD,separation voltage +13 kV,electrokinetic injection 11 kV×10 s. The calibration curve of the enantiomers showed good linearity in the range from 0. 8 mg/L to 40 mg/L with LOD =0. 3 mg/L. Effects of several factors on resolutions,such as the composition of the running buffer,the pH value,separation voltage,injection method and the parameters of C~4D detector,were investigated. The efficacy of the HP-β-CD and HPMC were discussed. The proposed method has been successfully applied to monitor the enantiomer of ofloxacin contents in the commercial Ofloacin Tablets and Levofloxacin Hydrochloride Tablets,and was demonstrated simple,rapid and reproducible.

Results Visual analogue score significantly decreasedafter the treatment (P<0.01), and severe dropsy after treatment was relieved in 2~3 weeks. Conclusion The cooled radiofrequency iseffective on refractory craniofacial postherpetic neuralgia, while the perioperative nursing care was safe, feasible, and worthy for more application.

Objective To analyze the clinical features and prognostic factors of patients with malignant tumor complicated by acute kidney injury (AKI),and provide the basis for preventing AKI and improving the prognosis.Methods Malignant tumor patients complicated by AKI were screened with the electronic medical records system from January 2001 to December 2012 at the Affiliated Hospital of Qingdao University.The clinical characteristics in the 12 years were analyzed by statistical analysis and compared.The risk factors of the hospital mortality in malignancies tumor complicated by AKI were analyzed by Logistic regression analysis.Results A total of 100 patients with malignant tumor complicated by AKI were collected,accounting for 24.94％ of AKI patients and 1.66‰ of malignant tumor patients at the same period.Malignancies were consist of hematologic malignancies (11％),non-metastatic solid tumor (47％),metastatic solid tumor (42％).The most common factor leading to AKI for malignancies was post-renal obstruction (64％),followed by nephrotoxic drugs or contrast agents (24％),hypovolemia (18％).There was no significant change of the etiologies for AKI between the first six-year and the second six-year (P ＞ 0.05).The hospital mortality of patients with malignant tumor complicated by AKI was 25％,and multivariate Logistic regression analysis showed that multiple etiologies (OR=13.356),multiple organ failure (OR=222.256),and metastatic solid tumors (OR=8.497) were the independent risk factors for hospital mortality.Conclusions AKI is a common complication in patients with malignant tumors,and the most common factor leading to AKI is postrenal obstruction.The hospital mortality in malignancies with AKI is high,which should get the attention of clinicians.

Objective To investigate the renal expression of stem cell factor (SCF) in lupus nephritis (LN) and its correlation with disease activity and renal injury parameters. Methods Histochemical stain was used to examine all renal specimens (LN group n=34, chronic glomerulonephritis n=16, control group n=8). Hyhridization in situ and immunohistochemistry were used to detect the expression of SCF and infiltration of mast cells, macrophages , α-SMA (+) cells in renal tissues of the two groups. SPS software was used for tissue of the control group. However, they increased markedly in lupus nephritis and CGN (t=6.03～14.25, P< 0.01). But there was no significant difference between LN and CGN in SCF and mast cells in renal interstitium. Positive correlation was observed among the expression of SCF and α-SMA and the number of mast cells and macrophages (r=0.47～0.84, P<0.01) at their corresponding locations. The expression of SCF and ot-SMA and the number of macruphages were positively correlated with renal pathological active index, chronic index, albuminuria and the injury of renal interstitium (r=0.34～0.93, P<0.05 or 0.01); meanwhile, it was negatively correlated with Ccr(r=-0.39～0.61, P<0.01). There was significant correlation between SCF, macrophages and anti-dsDNA antibody, complement C3 level, SLE disease activity index (SLEDAI). The number of mast cells in renal interstitium was positively correlated with chronic indexes and the injury of renal interstitium (r=-0.86, r=0.93, P<0.01) and negatively correlated with Ccr (r=-0.56, P<0.01), but not correlated with active index and albuminuria (r=0.27, r=0.23, P>0.05). Conclusion The expression of SCF is widespread in kidney, and it is markedly eorrelated with various kinds of inflammatory cells, renal inherent cells, renal function, and urine protein levels. SCF may be an critical participant in the initiation and progression of renal injuries in human lupus nephritis.

Transforming growth factor-β (TGF-β) is a multifunctional protein and regulates a wide variety of cellular bio-effects,such as proliferation,differentiation,migration and apoptosis.Studies have proven that TGF-β is one of the important cytokines that promote fibrosis,and it is confirmed to be closely related to the progression of tumor.Smad signaling is the major pathway in which TGF-β fulfills its functions.These years,it has been found that E3 ubiquitin ligases Arkadia can enhance the biological effect of TGF-β signal transduction pathway through Smad signaling pathway.Therefore,it is increasingly attracting public attention.This study will summarize the effects of Arkadia on TGF-β/Smad signal transduction pathway.

Objective To investigate the echocardiographic features of complete transposition of the great arteries (TGA)in fetuses.Methods Prenatal echocardiographic data of 9 fetuses diagnosed as TGA by autopsy or postnatal echocardiography during January 2010 to January 2017 were retrospectively analyzed.Results All of 9 fetuses showed normal cardiac axis and atrioventricular connection on four-chamber view.Eight of them showed the baby bird's beak sign on left ventricular outflow tract view.On left and right ventricular outflow tracts view,the two great arteries were parallel in 8 fetuses.Totally 6 fetuses showed just 2 vessels on three vessels and tracheal (3VT) view.On aortic arch view,the radian of aortic arch had increased in different degrees in 7 fetuses.There were 4 fetuses with ventricular septal defect observed by both of four-chamber and left ventricular outflow tract views.Conclusion The echocardiographic features of fetuses with TGA are characteristic in left ventricular outflow tract,left and right ventricular outflow tracts,3VT and aortic arch views,including baby bird's beak sign,2 great arteries' parallel relations,only 2 vessels on 3VT view,and increased radian of aortic arch.Of these features,baby bird's beak sign is the most common.
