ObjectiveTo study the sirolimus (SRL)-associated interstitial pneumonitis,which is a severe side effect of sirolimus therapy. Methods In 7 renal grafts treated with SRL, interstitial pneumonitis (8 times) was diagnosed. One patient suffered a relapse after sirolimus treatment was given again. Two patients received de novo sirolimus treatment, and rest 5 patients were switched from a calcineurin inhibitor-containing regimen to a SRL-based protocol for various indications: chronic allograft nephropathy (n = 4) and cancer (n = 1 ). The patients presented with fever, dyspnea on exertion and the chest X-ray or computed topographic (CT) scan on admission showed bilateral mostly peripheral interstitial infiltrates. ResultsSRL was discontinued in 4 patients and the dose was reduced in the remaining 3 patients. Symptoms were improved within 3-14 days in all patients, the radiographic findings improved within 2-4 weeks, and the lesions were absorbed completely in 2-6 months.ConclusionThe frequency of interstitial pneumonitis appears to be increased in renal transplant patients receiving SRL. Discontinuation or reduced dose of SRL appears to be the safest treatment option for the patients with interstitial pneumonitis.

Objective:To explore the effect of different separation and purification technology on the physical and chemical proper-ties of water extract of ophiopogonin. Methods:The water extraction process of total ophiopogon saponins was optimized by an orthogo-nal test. The macroporous resin adsorption and membrane separation technology were adopted to purify the ophiopogonin water extract. The physical and chemical parameters, such as electrical conductivity, pH value, viscosity and turbidity, and the contents of total sap-onins, proteins, tannins and polysaccharides were determined. Results:The optimum water extraction technology of total saponins was as follows:6-fold amount of water was added, boiling 3 times with 90 min for each time. The electrical conductivity, pH value and vis-cosity of different purified liquid of total saponins had no significant differences, while the contents of total saponins and the three kinds of macromolecules showed significant differences. Conclusion: The content of macromolecules can be used as the reference index of purification process of total saponins water extract. Compared with macroporous resin separation, membrane separation technology is more suitable for the separation and purification of total saponins water extract.

Objective Folate receptors ( FRs) , overexpressed on the surface of a variety of tumor cells , are potential targets for tumor targeting therapy .This study aimed to prepare an FR-mediated drug nanocarrier with folate conjugated pullulan acetate ( FPA) to target chemotherapeutic agents to FR-overexpressed tumor cells and investigate its tumor-suppressing effect in vitro. Methods The cytotoxicity of epirubicin-loaded FPA nanoparticles ( FPA/EPI NP) against HepG2 and Hela cells was evaluated by MTS assay.The HepG2 and Hela cells were divided into five groups to be treated with NPs (NP control), chlorpromazine, chloro-quine, amiloride, and folate, respectively, followed by detection of the fluorescence intensity by flow cytometry . Results FPA/EPI NP was successfully formulated into NPs , with the mean particle size of (268.5 ±12.0) nm, by dialysis with an almost spherical shape . The drug-loading rate and entrapment rate of FPA/EPI NP were (6.45 ±1.04) and (72.45 ±11.50) %, respectively.The survival rates of the HepG2 and Hela cells were both >95%after 24 hours of incubation with FPA NP at 5, 40, 200, 400 and 1000μg/mL and 90.0%after 72 hours.The survival rates of the HepG2 cells treated with 5, 40, 200, 400 and 1000μg/mL FPA/EPI NP for 24 hours were (92.3 ±5.2), (70.4 ±4.6), (50.0 ±4.0), (41.1 ±4.1) and (27.0 ±3.6) %, respectively.Compared with the NP control group, the Hela cells of the chlorpromazine , amiloride and folate groups showed a significantly lower rate of NP uptake (P<0.05), and so did the HepG2 cells pretreated with chlorpromazine or amilo-ride (P<0.05).At 72 hours, the half maximal inhibitory concentrations (IC50) of FPA/EPI NP against HepG2 and Hela cells were 168 and 105μg/mL, respectively . Conclusion Clathrin-mediated endocytosis and macropinocytosis are involved in the internaliza-tion of FPA/EPI NP in HepG2 cells, while clathrin-and FR-mediated endocytosis in that of Hela cells .FPA NP may serve as a new drug carrier for tumor-targeted therapy .

Objective To investigate the incidence of infection and the effect of anti-infection prophylaxis in renal transplanted patients after Basiliximab induction therapy. Methods A total of 204patients who have received renal transplantation and Basiliximab induction therapy from January 1,2001 to December 31, 2010 in our hospital have been retrospective analysed in this study. These patients were divided into a prophylaxis group (118 cases) with Ganciclovir + Sulfadiazine +Trimethoprim therapy and a control group (86 cases) without any anti-infection prophylaxis.Furthermore, 440 transplanted patients in the same peroid without any induction therapy were also analysed. They were also devided into two groups: an anti-infection prophylaxis group (206 cases)and a control group (234 cases) without any anti-infection prophylaxis. Results In the prophylaxis group with Basiliximab induction therapy, there were 23 patients (19. 5 %, 23/118)experienced hospitalization due to infection, 3 cases (13. 0 %,3/23) among them were severe infection, and 3patients (13.0 %, 3/23) died from vital infection. In the non-prophylaxis control group with Basiliximab induction therapy, 27 patients (31.4 %, 27/86) had infection complication, 7 patients (25.9 % ,7/27) among them were severe infection, and 4 patients(14. 8 % ,4/27)died. The incidence of infection between the above two groups is significantly different (P<0. 05). In the prophylaxis group without induction therapy, the incidence of infection was 15.0 % (31/206), there were no severe infection cases but 7 patients (22. 6 %, 7/31) died from infection. In the non-prophylaxis control group without induction therapy, the incidence of infection was 12. 8 % (30/234), 3 cases among them were severe infection(10. 0 %,3/30)and 5 patients died from infection (16. 7 %, 5/30).The incidence of infection in Basiliximab induced patients without anti-infection prophylaxis is significantly higher than that in patients without induction therapy and anti-infection prophylaxis (31.4 % vs. 12.8 %,P<0.01). Conclusion Basiliximab induction therapy increased the risk of infection, but not the rate of mortality. It is necessary to give anti-infection prophylaxis in renal transplanted patients with Basiliximab induction therapy.
