Objective To investigate thermal degradation kinetic characteristics of Cefmenoxime Hydrochloride in infusion solutions, and predict its thermal stability. Methods The HPLC was applied to determine the contents of Cefmenoxime Hydrochloride. Classical isothermal kinetic method and multivariate linear model were used to predict the expiration date of the injection. Results It was found that the thermal degradation kinetics of Cefmenoxime Hydrochloride in two infusion solutions corresponded with the first-order kinetics. The expiration dates of Cefmenoxime Hydrochloride in 0. 9%sodium chloride injection calculated by two different methods were 2. 20 days and 1. 52 days,and in 5% glucose injection were 2. 09 days and 1. 53 days,respectively. Conclusion The thermal stability of Cefmenoxime Hydrochloride in infusion solutions is poor and its expiration dates are the same calculated by two different methods.

Objective To investigate the influences of polyethylene glycol on the solubility and in vitro dissolution of m-nisoldipine,which could provide guidance for chosing formulations of m-nisoldipine. Methods Solid dispersions of m-nisoldipine were prepared by solvent-melting method with polyethylene glycol6000 matrix. DSC and XRD spectroscopy were applied to identify the solid dispersions. The solubility and in vitro dissolution were detected by UV spectroscopy. Results The DSC and XRD map were different from the crude drug and their physical mixtures. The dissolution rates(13,15,17) were faster(35. 31%,38. 71%,41. 48%) than that of the crude drug(26. 80%),and the dissolution rates of the solid dispersions in the same ratio were higher than the physical mixtures. Conclusion DSC analysis indicated that eutectic compounds were produced by the m-nisoldipine and polyethylene glycol,in which polyethylene glycol6000 acts as a carrier. The solubility and in vitro dissolution of m-nisoldipine can be increased.

Objective To explore ways to decrease peripheral vascular complications during parenteral nutrition through peripheral veins. Methods According to the support sequences of giving peripheral parenteral nutrition, ninty perioperative cases were randomly divided into low(20. 3 kPa·h-1 ),medium(27. 1 kPa·h-1 ) and high(33. 9 kPa·h-1 ) osmotic pressure rates(n=30 in each group). The infusion pump was used to control the rate of infusion. The total parenteral nutrient was infused through BD24G venous indwelling needles. The pain ratings at injection sites were evaluated after parenteral nutrition everyday,the incidences of phlebitis were observed three days later after removing the indwelling needles. ResultsUnder the low osmotic pressure,the pain was mild,while for the medium osmotic pressure,the pain became more obvious. The pain was aggravated obviously under high osmotic pressure. There were only two cases of over grade-II phlebitis under low osmotic pressure rate,9 cases under medium osmotic pressure rate and 14 cases under high osmotic pressure rate, in which a grade-Ⅲ phlebitis developed. Conclusion Decreasing the osmotic pressure rate through peripheral venous is an effective method to avoid or reduce the incidences of peripheral vascular complications with the peripheral parenteral nutrition support.

Objective To investigate interventions of vitamin E( VE) on indomethacin-induced gastric mucosal injury. Methods Fifty mice were randomly divided into 5 groups. Normal control group was administrated with saline, others were intragastrically administrated with indomethacin ( 20 mg · kg-1 ) . After 4 hours, mice were intragastrically treated with saline, cimetidine(200 mg·kg-1),VE(25,50 mg·kg-1) once a day for 5 consecutive days. By the end of the treatment,gastric mucosa injury index,serum superoxide dismutase(SOD) activity,and malondialdehyde(MDA) content were determined. ResultsGastric mucosal injury indexs of mice treated with cimetidine,VE at low and high doses were significantly lower than that of the model control and higher than that of the normal control(P<0. 01). VE at high doses showed significantly less mucosal injury than that of the cimetidine group(P<0. 05). Healing-rate of gastric mucosal injury in cimetidine group,VE low-dose and high-dose groups were significantly higher than that of model control group(P<0. 01). SOD activity of VE at low and high doses was significantly lower than that of the model control and cimetidine groups(P<0. 05). The results also revealed that cimetidine and two doses of VE significantly elevated SOD activity and lowered the level of MDA(P<0. 05, 0. 01). Conclusion VE can obviously promote the healing of gastric mucosal injury,especially at high dose,which is better than cimetidine,while,the low dose is comparable with cimetidine.

Herald of Medicine.2014;(5):586-589. doi:10.3870/yydb.2014.05.010

Objective To study the effects of enteral nutrition( EN) on inflammatory factors and cardiac function in elderly patients with heart failure ( HF ) . Methods A total of 96 elderly patients with HF were enrolled in this study and randomly divided into treatment group A,treatment group B and control group( n= 32 in each group) . Patients in group A were provided with 500 mL of EN daily for 1 month, and those in group B were provided with the same dose of EN for 3 months. Control group was treated with normal diet. The nutrition status of each group was assessed by NRS2002. Meanwhile,all patients were evaluated by New York Heart Association(NYHA) class and left ventricle eject fraction(LVEF). The levels of BNP,IL-6, CRP and TNF-α were also measured before and after nutrition treatment. Results In group A and group B,BMI,TSF,AMC, TP,ALB and HGB increased. Symptoms of HF alleviated quickly and LVEF increased compared to the baseline. The levels of BNP,IL-6,CRP and TNF-α were significantly lower after treatment(P<0. 05) in both treatment groups,and the change in group B was more obvious(P<0. 01) than group A. However,in control group,there is neither evident improvement in cardiac function or nutrition status,nor in inflammatory factor levels. Conclusion Adding EN support to the normal treatment of heart failure in elderly malnourished patients with HF not only improves the function of heart and nutrition status, but also helps to support immune system so as to alleviate acute inflammatory response. The benefits from EN depend on the duration of therapy.

Herald of Medicine.2014;(5):582-585. doi:10.3870/yydb.2014.05.009

Objective To explore the correlation of E-cadherin expression and the sensitivity to EGFR-TKI molecular targeted therapy. Methods Eight kinds of cells,MCF-7,MDA-MB-231,T24,SiHa,H460,SK-HEP-1,MHCC97-H and THP-1 were treated with EGFR-TKI PD153035 and gefitinib,respectively,for 48 hours. The drug-sensitivity was detected by MTT,and the IC50 of cells were calculated. The E-cadherin protein were detected and compared. Results Followed with PD153035 and gefitinib treatment,the survival rates of MCF-7,MDA-MB-231,T24 and SiHa significantly reduced,and more E-cadherin protein expressed. However, the survival rates of the H460, SK-HEP-1, MHCC97-H, and THP-1 cells showed opposite results. Conclusion The sensitivity of epithelial cancer cells to EGFR-TKI is correlated with E-cadherin expression. E-cadherin may play a significant role on regulateing the sensitivity to EGFR-TKI molecular targeted therapy. E-cadherin is a key biomarker for recruiting appropriate patients for EGFR-TKI molecular targeted therapy.
