In order to study the antibacterial activity of Chinese medicinal herbs to Ureaplasma ure- alyticum(Uu),we examined the inhibitory effect of 156 Chinese medicinal herbs to 14 standard strains of Uu by microdilution method in vitro.The results showed that Uu had a higher sensitivity to Cortex phellodendri,Radix angelicae dahuricae,Fructus kochiae,Radix et rhizoma rhei(MIC_(90)≤7.81mg of dried medicinal herbs/ml);a moderate sensitivity to Radix glycyrrrhizae,Radix isatidis,Rhizoma cop- tidis,Herba andrographitis,Herba houttuyniae(15.63≤MIC_(90)≤62.5);a lower sensitivity to Cortex meliae,Herba leonuri(62.5250).It is our opinion that Chinese medicinal herbs are of momentous signfi- cance in the treatment of Uu infection.

To investigate the effects of different surface conditioning methods on the shear bonding strength of glass-infiltrated ceramic to dentine, 24 glass-infiltrated ceramic testing-pieces were divided into four groups randomly. Among them 3 groups were treated with A(sandblasting+silance), B(etching+silace) or C(silance), separately, while group D was set as the control. Bonding the ceramic pieces to dentine with Super-Bond and the shear bonding strengths was measured. The results showed that the shear bonding strength of group D was lower than that of group A, B and C (P0.05). It is suggested that surface conditioning using combined sandblasting with silance can remarkbly improve the shear bonding strength of glass-infiltrated ceramic to dentine.

Objective To explore the effects of alanyl-glutamine (Ala-Gln) dipeptide supplemented parenteral nutrition (PN) on the short-term outcomes in critically ill adult patients.Methods In this retrospective study,we reviewed the clinical data of critically ill adult patients who were treated by standard PN from January 2006 to December 2011.The length of stay in intensive care unit (ICU-LOS),incidences of infections and multiple organ dysfunction syndrome (MODS),and mortality were compared between the group of Ala-Gln dipeptide supplemented PN (intervention group) and the group of PN without Ala-Gln dipeptide (control group).Results Finially,617 cases were enrolled in the study,including 312 cases in the control group and 305 cases in the intervention group.The ICU-LOS was significantly shorter in the intervention group than that in the control group [(17.2 ± 6.5) d vs.(16.1 ± 5.3) d,P =0.011).Compared with the control group,the incidences of infection (42.9％ vs.33.1％,P =0.011) and MODS (46.5％ vs.38.0％,P =0.030) and the mortality (34.9％vs.25.9％,P =0.014) in the intervention group patients were significantly lower.Conclusion Ala-Gln dipeptide supplemented PN can improve the short-term outcomes of critically ill adult patients.

Objective To investigate the outcomes of unselected peripheral T cell lymphoma (PTCL) patients treated with in-tensive first-line chemotherapy with high-dose therapy followed by autologous stem cell transplantation (ASCT).Methods Here a nonrandom study was reported for 23 PTCL patients treated with first-line intensive chemotherapy followed by autologous stem cell trans-plantation and 23 PTCL patients treated with conventional chemotherapy during January in 2000 to 2011 .All patients had received E-CHOP for 6~8 cycles, and autologous stem cell transplantation group was administrated with intensive chemotherapy followed by ASCT after complete remission or partial remission .Results There was no statistically significant difference in short-term therapeutic effect between two groups( P >0.05), but the 5-year overall survival(OS) of autologous stem cell transplantation group( 58%) was higher than conventional chemotherapy group , as well as 5-year disease-free survival time (DFS) (45%in autologous stem cell transplanta-tion group, and 21%in conventional chemotherapy group ) with both statistical significance ( P <0.05).Only the incidence of Ⅳ° myelosuppression in autologous stem cell transplantation group ( 100%) was higher than that in conventional chemotherapy group ( 13%) ( P <0.01 ) .Conclusions First-line intensive chemotherapy followed by autologous stem cell transplantation for peripheral T cell lymphoma was quietly safe utility , it was better than conventional chemotherapy which would be considered as first -line method.

Objective To explore the impacts of different nutrition support methods on short-term outcome in critically ill adult patients. Methods We retrospectively reviewed the clinical data of 1503 critically ill adult patients who needed nutrition support in an mixed intensive care unit (ICU) of a tertiary care university hospital from January 1994 to December 2009. The complication of nutrition support, length of stay (LOS) in ICU, morbidity of infection and multiple organ dysfunction syndrome (MODS), and mortality among different nutrition support methods were compared. Results The Nutritional Risk Screening (NRS) scores of the enrolled patients were no less than 3. LOS in early enteral nutrition (EN) patients were significantly shorter than those in not-early EN patients (P ＜ 0. 001) and parenteral nutrition (PN) patients (both P ＜ 0. 001). Infection rate (P ＜ 0. 001),morbidity of MODS (P ＜ 0. 001) and mortality (P ＜ 0. 001) were significantly lower than those in not-early EN and PN patients. LOS of patients receiving PN rich in glutamine (Gln) was significantly shorter than that in conventional formula (P = 0. 0000). Morbidity of infection (P= 0. 0252) and MODS (P = 0. 0030), mortality (P =0. 0305) were significantly lower than that of conventional patients. LOS of patients receiving intensive insulin therapy (IIT) was significantly shorter than that of controlled group (P = 0. 0000). Morbidity of infection (P =0. 0001) and MODS (P = 0. 0237) and mortality (P =0. 0427) were significandy lower than those of controlled group. Conclusions Nutritional risk is prevalent among critically ill adult patients. Early EN, PN of rich in Gln,and receiving IIT can shorten LOS, decrease morbidity of infection and MODS, and improve prognosis among these patients.

OBJECTIVE： To evaluate the clinical therapeutic effect of L-glutamine granules on intestinal damage of severe burn patients and the safty of the drug.METHODS： Thirty-nine severe burn patients were randomly divided into two groups： control group（C group， nineteen patients） and L-glutamine treatment group（GLN group， twenty patients） .GLN group patients were given L-glutamine in a dose of 30g per day for 7 days， and C group patients were given the same dosage of placebo for 7 days.The plasma L-glutamine concentration， the degree of intestinal mucosa damage， blood biochemistry and complication were observed and wound healing rate of burn area was determined， then the length of hospital stay was recorded.RESULTS： After 7 days of taking L-glutamine orally， plasma L-glutamine concentration in GLN group was significant higher than that in C group（P<）. The degree of intestine damage and intestinal mucosal permeability in GLN group were lower than those in C group. In addition, the wound healing rate was faster and the length of hospital stay was shorter in GLN group than those in C group. CONCLUSION: Administration of L-glutamine could abate the degree of intestine damage obviously, lessen intestinal mucosal permeability, ameliorate wound healing rate and reduce the length of hospital stay.

Background and purpose:In preparation for using this tracer in humans, this study estimated thedosimetry of18F-FES with the method established by MIRD based on whole-body PET imaging of mice.Methods:Three female mice receivedⅣ tail injections of18F-FES and were scanned for 160 min in an Inveon dedicated PET/CT scanner. This study selected some important organs (brain, lung, liver, heart wall, small intestine, large intestine, kidney and urinary bladder), computed their residence times. Then, the residence times in mice organs were converted to human values using scale factors based on differences between organ and body weights. OLINDA/EXM 1.1 software was used to compute the absorbed human doses in multiple organs for both adult female and adult male body phantoms. Results:The highest absorbed doses in gallbladder wall, urinary bladder wall, small intestine, upper large intestine and liver are 0.072 5, 0.044 5, 0.043 0, 0.031 5 and 0.028 2 mGy/MBq, respectively. The organs which have the lowest ab-sorbed doses were brain (0.005 2 mGy/MBq), followed by skin (0.001 1 mGy/MBq), breast (0.001 1 mGy/MBq), heart wall (0.001 2 mGy/MBq) and thyroid (0.001 2 mGy/MBq). The mean absorbed doses for the other major organs ranged from 0.009 5 to 0.023 5 mGy/MBq. The total mean effective dose is 0.019 0 mSv/MBq and the mean effective doses equivalent is 0.025 0 mGy/MBq. A 370-MBq injection of18F-FES leads to an estimated effective dose of 7.03 mSv for the female. There was no statistical difference in the doses results obtained from direct measurement of18F-FES ab-sorption in normal people between previous publications by others and our work.Conclusion:The whole-body mouse imaging can be used as a preclinical tool for initial estimation of the absorbed doses of18F-FES in humans. Furthermore, the potential radiation risk associated with18F-FES imaging is well within the accepted limits.
