Objective To investigate the protective effects of statins on renal function in patients with severe acute pancreatitis(SAP). Methods Fifty-seven SAP patients combined with AKI were divided into statins group(n = 27)and control group(n = 30). The level changes of amylase(AMY),blood uria nitrogen(BUN), creatinine(Cr),total cholesterol(TC),triglyceride(TG),low density lipoprotein cholesterin(LDL)and high density lipoprotein cholesterol(HDL) before and after statin treatment were observed in statins group and then all were compared with those in control group. Results There was no significant difference of AMY,BUN,Cr,TC,TG, LDL and HDL between 2 groups before treatment. After treatment,AMY,BUN,Cr,TC and LDL were significantly lower while HDL were significantly higher in two groups(P<0.05). However,AMY,BUN and Cr were far lower on 7th day and 14th day in statins group than those in control group(P<0.05). Simultaneously,TC and LDL were far lower while HDL were far higher 14thday in statins group when compared with those in control group(P < 0.05). Conclusions Statins have protective effects on renal function in patients with SAP ,and the mechanism is probably related to the inhibition of HMG-COA ,elimination of oxygen free radicals and anti-fibrosis.

The view of "Harmony between Man and Nature" in Song-Ming period,taking "the same rule of man and nature" as mode,"clearing the rules according examining the things" as means,made the doctors of vital gate school in traditional Chinese medicine set up a life pattern of "taiji(vital gate)-yin and yang-five elements(zang-fu viscera)",so as to explore the origin of life and mystery.The study on the characteristics of view of "Unity of Heaven and Man" in different historical stages is conducive to grasp the track and skeleton of the formation of traditional Chinese medical theories,lay the foundation for the further development of traditional Chinese medicine.

BackgroundOur previous research and other reports disclosed that the expression of tissue transglutaminase(tTG)in lens epithelial cells(LECs) of patients with cataract is enhanced,indicating tTG is related to formation of posterior capsule opacification(PCO).ObjectivePresent study is to observe the effect of tTG specific inhibitor monodansyl-cadaverineon(MDC) on the expression of fibronectin(FN) and collagen Ⅳ(Col-Ⅳ) induced by TGF-β_2 in human LECs.MethodsHLE-B3 was cultured in vitro in DMEM containing 10% fetal bovine serum and then were divided into 5 groups.The free-serum culture was used as normal control group.Free-serum culture containing 10μg/L TGF-β_2 was utilized as treatment group.10μg/L TGF-β_2 plused 100μmol/L,200μmol/L and 400μmol/L MDC respectively in different concentrations as MDC-treatment group.Semiquantitative RT-PCR was used to assay the expression of tTG,FN and Col-Ⅳ in HLE-B3.A(tTG/β-actin),A(FN/β-actin) and A(Col-Ⅳ/β-actin) was calculated separately as the detecting indexes.ResultstTG,FN and Col-Ⅳ were positively expressed in cultured HLE-B3.The expression levels of tTG,FN and Col-Ⅳ in HLE-B3 were remarkably increased in the group with 10μg/L TGF-β_2 compared with normal control group(t=33.95,P<0.01;t=38.24,P<0.01;t=13.48,P<0.01).The expression levels of FN and Col-Ⅳ were gradually declined in 100,200 and 400μmol/L MDC groups in comparison with TGF-β_2 treatment(P<0.01).The significant differences were also found in the expressions of FN and Col-Ⅳ in HLE-B3 among 100,200 and 400μmol/L MDC groups(P<0.01).ConclusionMDC inhibits the expression of FN and Col-Ⅳ induced by TGF-β_2 in human LECs at a concentration-dependent manner.tTG may be involved in the formation of posterior capsule opacification through up-regulating the expressions of FN and Col-Ⅳ in human LECs.

Objective To explore the relationship between serum placental growth factor (PLGF) and carotid atherosclerosis (CAS) in patients with type 2 diabetes mellitus (T2DM ). Methods Serum PLGF were determined by ELISA in 53 patients with T2DM ,who were divided into T2DM without carotid plague (T2DM group ,n= 27) and T2DM with carotid plague (T2DM + CAS group ,n= 26). Fasting plasma glucose (FPG) ,glycosylated hemoglobin A1c (HbA1c) and some other metabolic variables were also measured. The results were compared to those of 27 healthy controls (NC group). Results Serum PLGF levels were significantly higher in T2DM group and T2DM + CAS group than in NC group (P<0.01). T2DM+CAS group showed significantly higher serum levels of PLGF compared to that of T 2DM group(P<0.01).Correlation analysis showed that serum PLGF was positively correlated with TC ,LDL‐C , hsC‐RP and IL‐6 in T2DM patients (P<0.01). Similarly ,multiple regression analysis showed that LDL‐C and IL‐6 were the independent factors of serum PLGF level (P<0.05). Furthermore ,Serum PLGF was positively associated with carotid plague. Conclusion PLGF is positively related with chronic inflammation factors in T2DM patients. Serum PLGF may play an important role in the occurrence and development of carotid atherosclerosis and other macroangiopathy in T 2DM.
