Objective To study the process of foam fractionation of polyphyllin in semi-batch mode. Methods Taking enrichment ratio, recovery rate of polyphyllin, and purity ratio as the performance criteria and using single examining method to examine the operational parameters, i.e. operation mode, air flow rate, initial feed concentration, solution pH value, initial feed height and temperature on separation performance. The optimal conditions of the process were obtained finally. Results The separation performance is good when gas flow rate is 400 mL/min, initial feed concentration (polyphyllins content) is 0.3 mg/mL, pH value is 7, feed height is 30 cm, and feed temperature is 40 ℃. The enrichment ratio is 25.7, recovery ratio is 42.1%, and the foam liquids purity of total polyphyllin is 41.4%, which is 4.5 times higher than that in feed purity. Conclusion Foam fractionation technique could be applied to separate polyphyllin.

ObjectiveTo explore the effect of doctor-nurse integration mode in treating patients with liver cirrhosis treated with endoscopic variceal ligation (EVL).Methods According to the random number table,74 patients were randomly divided into control group and experiment group with 37 in each group.The control group was given routine nursing,while the experiment group was managed by doctor-nurse integration nursing mode.The two groups were compared in respect of early re-bleeding after EVL and mastery of health knowledge.Result The mastery of health-related knowledge in the experiment group was better than the control one and the rate of re-bleeding was significantly lower (P<0.05).Conclusion The doctor-nurse integration care mode can reduce the early postoperative re-bleeding after EVL in patients with liver cirrhosis and enhance the health education awareness.

Objective To explore the value of peripheral blood serum levels of PCT,CRP,TNF-α and free DNA of cells in predicting the development of MODS in patients with multiple trauma.Methods Complete detail clinical data of 54 casualties with multiple trauma admitted within 24 hours after accident from January 2011 through January 2012 were collected for retrospective study.The patients were divided into MODS group and non-MODS group according the criteria set forth by the Chinese Society of Critical Care and Emergency Medicine in 1995 national conference.The data of two groups are comparable,and data of another 20 healthy subjects undertaking routine annual physical examination were taken as control.The peripheral blood levels of PCT,CRP,TNF-α and free DNA of patients of two groups were determined 1 d,2 d,3 d,and 5 days after admission.Then the results were analyzed and compared between groups.Results Compared with non MODS group,the levels of PCT,CRP,free DNA of cells in MODS group were significantly higher (P ＜ 0.05),but there was no deference in TNF-α between MODS group and non-MODS group (P ＞ 0.05).When the relative risks of increased PCT (PCT≥6 mg/L),increased CRP (CRP≥ 130 mg/L)、and increased free DNA of cells (free DNA ≥ 10 0005/L) were analyzed,the presence of these 3 biomarkers with high levels occurred at the same time was the most accurate way to predicts MODS in 6.00 relative risk (RR),and the positive predictive value was 100％.Conclusions PCT,CRP,free DNA of cells could be the predictors of MODS in patients with severe multiple trauma,and the presence of high levels of these three biomarkers appearing together had high sensitivity and specificity for prediction.

OBJECTIVETo investigate the role of endogenous hydrogen sulfide (H2S) in erectile dysfunction (ED) induced by androgen deficiency.

METHODSWe randomly divided 30 eight-week-old healthy male SD rats into six groups: 2-week control (A), 4-week control (B), 2-week castration (C), 4-week castration (D), 2-week castration + androgen replacement (E), and 4-week castration + androgen replacement (F), those in groups E and F subcutaneously injected with testosterone propionate (TP) at the physiological dose of 3 mg/kg per day after castration, while those in the other groups with isodose oil instead. At 2 and 4 weeks after operation, we determined the level of serum testosterone (T) , intracavernous pressure (ICP) , mean carotid arterial pressure (MAP) of the rats, measured the concentration of H2S in the plasma and corpus cavernosum tissue, and detected the expressions of cystathionine-P3-synthase (CBS) and cystathionine-gamma-lyase (CSE) by immunohistochemistry and Western blot.

RESULTSThe serum T level was significantly lower in group C ([0.63 +/- 0.15] nmol/L) than in A ( [ 16.55 +/- 4.17] nmol/L) and E ( [ 18.99 +/- 4.62] nmol/L) (P <0.05), as well as in group D ([0.70 +/-0.22] nmol/L) than in B ([15.44 +/-5.18] nmol/L) and F ([20.99 +/-6.41] nmol/L) (P <0. 05) , and so were ICP/MAP after 5 and 7 V electrical stimulation of the pelvic ganglia (P <0. 05) , H2 S concentration (P <0.05), and the expressions of CBS and CSE (P <0.05). The expressions of CBS and CSE proteins were also significantly decreased in group C as compared with D (P <0.05).

CONCLUSIONThe reduced expressions of CBS and CSE may inhibit the H2 S signaling pathway, which might be one of the mechanisms underlying androgen deficiency-induced ED in rats.

OBJECTIVETo observe the effects of low-dose exogenous estrogen nonylphenol (NP) on the proliferation of human prostate cancer cell lines DU-145 and the expression of the membrane estrogen receptor GPR30 in the DU-145 cells.

METHODSWe exposed DU-145 cells to different concentrations of NP for 24 hours, followed by measurement of the half maximal inhibitory concentration (IC50) of the cells by cell proliferation assay and determination of the concentration of exposure to low-dose NP. We also observed the expressions of 3 estrogen receptors (ER), including ER-alpha, ER-beta and membrane estrogen receptor GPR30, in the DU-145 cells exposed to low-dose NP by RT-PCR.

RESULTSCell proliferation assay showed that within a certain range of doses, NP inhibited the proliferation of the DU-145 cells with an IC50 of 46 micromol/L, a much lower dose of NP than IC50, 0.01, 0.1.1 micromol/l NP, that can promote the proliferation of DU-145 cells. The results of RT-PCR indicated that the expressions of the three ERs in the DU-145 cells were similar to those in prostate epithelial cells, and that low-dose NP promoted the expression of GPR30.

CONCLUSIONMembrane estrogen receptor GPR30 may play a role in low-dose NP promoting the proliferation of DU-145 cells.
