Objective To investigate the expression of peroxisome proliferator-activated receptor-γ(PPAR-γ) and angiotensin receptor (AT2R) in chronic pancreatitis tissue. Methods Between April 2006 and February 2009, 24 patients were pathologically diagnosed as chronic pancreatitis were enrolled and 12 samples of normal pancreatic tissues were treated as controls. Immunohistochemical staining was used to detect PPAR-γ and AT1R, AT2R expression in pancreatic tissues. Results PPAR-γ and AT1R were mostly negatively expressed in normal pancreatic tissues, the positive scores were 0.33±0.49 and 0.42 ± 0. 51, respectively, while AT2R were weakly positively or negatively expressed in acinus and islet cell, and it was weakly positively expressed in ductal epithelial cells, the positive score was 2. 33 ± 1. 37. In chronic pancreatitis tissue, PPAR-γ, AT1R and AT2R were positively expressed in acinus, ductal epithelial cells, and islet cell, the positive scores were 3.28 ± 2.46, 4.36 ± 2.80 and 4.61 ± 2.89, which were significantly higher than those in the normal group (P<0.01, P <0.01, P<0.05). Conclusions PPAR-γ, AT1R and AT2R were positively expressed in chronic pancreatitis tissue, and they may be the treatment target of chronic pancreatitis.

Objective A new type adsorbent for removal of bacterial ET was prepared by immobilizing L-serine covalently onto polyvinylidene difluoride membrane (PVDF-Ser) to study the effect of hemoperfusion on sepsis induced lung injuries in a pig model. Method Endotoxemia were induced in thirteen pigs by injecting endotoxin (1 μg/(kg·h) ) intravenously for 2 h. One hour later, the pigs were treated with absorber of PVDF-Ser volumn (group hemoperfusion) or empty adsorber (group control) for 2 h. Extravascular lung water indexed to body weight and alveolar capillary permeability, levels of serum endotoxin, tumor necrosis factor-α, interleukin-6, malondialdehyde, glutathione, myeloperoxidase activity, and lung histological changes and myeloperoxidase immunohistochemical analysis were measured. Results Hemoperfusion treatment with PVDF-Ser volumn significantly improved extravascular lung water, pulmonary alveolar capillary permeability and lung injuries ( P ＜ 0. 05). In addition, hemoperfusion attenuated both serum and pulmonary cytokines, and decreased lung malondialdehyde and myeloperoxidase levels ( P ＜ 0. 05). Conclusions Hemoperfusion with the adsorber of PVDF-Ser volumn effectively reduced inflammatory responses and improved lung injuries and oxidative stress in endotoxemia. It has a high potential of clinical application for treatment of patients with severe sepsis.

OBJECTIVE:To investigate therapeutic efficacy and safety of levamlodipine and telmisartan combined with hydro-chlorothiazide in the treatment of anti-dipper hypertension. METHODS:Totally 150 patients with anti-dipper hypertension were ran-domly divided into group A,B,C,with 50 cases in each group. Group A was given Telmisartan tablet 40 mg+Hydrochlorothiazide tablet 10 mg,once a day,in the morning. Group B was given Levamlodipine tablet 5 mg,once a day,in the night. Group C was given Telmisartan tablet(usage and dosage same as group A)+Hydrochlorothiazide tablet(usage and dosage same as group A)+Le-vamlodipine tablet(usage and dosage same as group B). Treatment courses of 3 groups lasted for 8 weeks. The changes of electro-lyte and 24 h ambulatory blood pressure were observed and compared among 3 groups before and after treatment. The incidence of adverse reactions was recorded. RESULTS:There was no statistical significance in the electrolyte indexes in 3 groups before and af-ter treatment(P>0.05). Before treatment,there was no statistical significance in 24 h blood pressure among 3 groups(P>0.05). Af-ter treatment,the 24 h blood pressure of the patients in the 3 groups after treatment was lower than before treatment,and group C was lower than that of the group A and group B(P<0.05). After treatment,the rate of anti-dipper rhythm reversal in group C was significantly higher than group A and B,with statistical significance(P<0.05). There was no statistical significance in the inci-dence of ADR among 3 groups(P>0.05). CONCLUSIONS:Levamlodipine and telmisartan combined with hydrochlorothiazide show good therapeutic efficacy for anti-dipper hypertension,and can reduce 24 h blood pressure and effectively reverse anti-dipper rhythm with good safety.
