Objective To optimize the formulations of venlafaxine hydrochloride ( VH ) emulsions by using central composite design-response surface methodology. Methods The effect of amounts of Arlacel P135, VH, PEG-400, and NaCl on the emulsion viscosity, centrifugation breakage, and mean diameter was systemically investigated, respectively. The desirable formulation that combining these three response variables was constructed. Linear equations and a second-order polynomial equation were fitted to the data, and the outcome equation was used to predict the responses in the optimal region. Results There was a quantitative relationship between 4 factors and 3 evaluation indexes and evaluation the “desirability” . The optimal formulation of the VH emulsion were as follows:taking 0. 48 g of Arlacel P135, 0. 40 g of VH, 0. 26 g of PEG-400, and 0. 025 g of NaCl. The experimental values of the response variables were highly closed to the predict values. Conclusion The model presents good prediction and can be used to optimize the preparation of VH emulsion, which obtaining stable W/O emulsion.

Objective:To evaluate the impact of atorvastatin and rosuvastatin at different doses on liver function in the patients with coronary artery disease. Methods:A retrospective study was used, and the patients with coronary heart disease hospitalized in the first hospital of China medical university from January 2013 to March 2014 were selected. According to the drug variety and dosage, the patients were divided into four groups: A (atorvastatin, 20 mg·d-1), B (atorvastatin, 40 mg·d-1), C (rosuvastatin, 10 mg· d-1 ) and D ( rosuvastatin, 20 mg·d-1 ) . The basic information of patients, the indices of liver function( ALT,AST,ALP and TBIL) , the time of abnormal liver function, treatment strategies and prognosis were recorded. The incidence of abnormal liver function in the groups was compared, and the rationality and effectiveness of the intervetion strategies were evaluated. Results:A total of 269 patients were collected. Among them, 149 cases were with abnormal liver function in varying degrees, and 21 patients were with ALT>3?ULN. The incidence of ALT>3?ULN in atorvastatin high dose group was much higher than that in atorvastatin low dose group( P<0. 05). Conclusion:The patients treated with high dose atorvastatin (40 mg·d-1) have a high risk of liver injury.

Objective To evaluate the efficacy of angiotensin converting enzyme inhibitor (ACEI) and angiotensin receptor blocker (ARB) in the treatment of idiopathic pulmonary fibrosis through the method of system evaluation. Methods A computer-based online search of Pubmed, Embase, Cochrane Library, CNKI, CBM and Wanfang were used for database retrieval. Revman 5.0 was used to assess the bias of the included studies. The Stata 14.0 was used to evaluate the extraction indexes of efficacy, p (O2), p (CO2), DLco, FEV1 and VC. GRADE score was used to evaluate the level of evidence. Results A total of 17 articles (related with 1381 patients) were included in this study, including 14 studies using ARB and 3 studies using ACEI. Compared with the control group ACEI and ARB drugs showed advantages in the treatment of pulmonary fibrosis (RR=1.34, 95%CI:1.24-1.44, Z=7.81, P<0.001). Auxiliary index analysis showed that the test groups were treated with enalapril (SMD=0.72, 95%CI:0.21-1.22, Z=2.77, P=0.006), telmisartan (SMD=3.86, 95%CI:2.44-5.27, Z=5.35, P<0.001), valsartan (SMD=1.94, 95%CI:1.33-2.55, Z=6.27, P<0.001) and captopril (SMD=0.60, 95%CI:0.11-1.09, Z=2.41, P=0.016), the p(O2) levels were significantly improved in patients ≥65 years old (SMD=0.76, 95%CI:0.52-1.00, Z=6.18, P<0.001) and patients < 65 years old (SMD=3.97, 95%CI:2.61-5.32, Z=5.73, P<0.001), and disease duration≥5 years (SMD=1.39, 95%CI:0.45-2.33, Z=2.89, P=0.004) and disease duration<5 years (SMD=3.26, 95%CI:2.06-4.46, Z=5.34, P<0.001) compared with those of control group (SMD=2.95, 95%CI:1.95-3.94, Z=5.82, P<0.001). The curative effect of telmisartan was better than that of other drug groups (P < 0.001), and which was much better for patients under 65 years old (P<0.001). There was no significant difference in the disease duration between two groups (P=0.307). The p (CO2) levels were significantly improved in patients treated with telmisartan [SMD=-12.94,95%CI:(-14.01)-(-11.86),Z=23.51,P<0.001), valsartan [SMD=-1.95,95%CI:(-2.56)-(-1.34),Z=6.29,P<0.001] compared with those of control group [SMD=-11.13,95%CI:(-17.03)-(-5.24),Z=3.70,P<0.001]. The effect of telmisartan was better than that of valsartan (P<0.001). In addition, values of DLco (SMD=0.64, 95%CI:0.45-0.83, Z=6.72, P<0.001), FEV1 (SMD=1.19, 95%CI:0.52-1.86, Z=3.47, P<0.001) and VC (SMD=0.51, 95%CI:0.16-0.85, Z=2.85, P=0.004) were improved in test group compare with those of control group. And the GRADE scores of relevant indexes were low quality to moderate quality. Conclusion ACEI and ARB can improve the efficacy, the p (O2) and p (CO2) in the treatment of pulmonary fibrosis. Patients with age<65 years old and treated with telmisartan have the best curative effect, and which is not related to the disease duration.

Aim To study effects of loganin and morro-niside on aging astrocytes induced by D-galactose. Methods Cortex astrocytes of newly born rats were cultured in vivo and indentified by immunofluorescence method.Firstly,appropriate D-galactose concentration was selected and effects of loganin and morroniside on proliferation activity of aging astrocytes induced by D-galactose were determined by MTT test.Then SOD, MDA were taken as indicators to study the effects of loganin and morroniside on aging astrocytes induced by D-galactose.Thirdly,growth factors like gliar cell line-derived neurotrophic factor (GDNF),basic fibro-blast growth factor (bFGF)tested by ELISA method and expression of Bax,caspase-3,phospho-extracellu-lar signal-regulated kinese (p-ERK1 /2),phospho-mi-togen-actived protein kinase /extracellular signal-regu-lated kinase kinase (p-MEK1 /2)were taken as indi-cators to discuss the potential protection mechanism. Results Loganin and morroniside exerted certain effects on proliferation of aging astrocytes induced by D-galactose,improving SOD,GDNF,bFGF release and lowering MDA release significantly (P <0.05 ). The expressions of Bax and caspase-3 proteins had no difference between model group and loganin group, morroniside group.While the expressions of p-ERK1 /2,p-MEK1 /2 of loganin group,morroniside group were improved significantly compared with model group.Conclusion Loganin and morroniside have protective effects on aging astrocytes induced by D-ga-lactose,and increase the proliferation ability.Protec-ting their antioxidant systems and improving the expres-sion of p-ERK1 /2,p-MEK1 /2 proteins are possible mechanisms.
