Objective To construct a novel M.tb DNA vaccine (p846) co-expressing mycobacterial triple antigens including Rv3615c, Mtb10.4 and Rv2660c, and evaluate its cellular immune response and protective efficacy against tuberculosis infection in BALB/c mice. Methods We constructed the p846 by using the cloning technology. The 6- to -8-week old female BALB/c mice were randomly divided into 4 groups: p846, pcDNA3.1, PBS and the BCG group. All mice were administrated intramuscularly with 50 μg recombinant plasmids at 0, 2, 4, 6 week. A single dose of BCG was injected subcutaneously in the BCG group. Two weeks after the final immunization, 10 mice in each group were used for cell proliferation, ELISPOT and FCM assay, BCG challenge experiment and HE staining of lung were performed at 4, 6 weeks later, respectively. Results The p846 vaccine could effectively induce the specific T cell proliferation(P < 0.001) and increase the numbers of IFN-γ+T cells(P <0.001), compared with those in the PBS group and the vector conreol group. The mouse lung tissue presented very mild lung inflammation in the p846 group, compared with other groups. Conclusion Vaccine p846 could not only induce strong cellular immune response, but also efficiently protect BALB/c mice against M.tb infection.

Objective To study characteristics and immune mechanisms of CD11b+ GR-1-myeloid-derived suppressor cells (CD11b+ GR 1+ MDSCs) in elderly mice,as compared with those of healthy young mice.Methods Totally 20 healthy C57BL/6 young mice (aged 1-2 months) and 20 elderly mice (aged over 18 months) were randomly chosen and splenetic CD11b+ GR-1+ MDSCs were sorted with the MDSCs Isolation Kit.In vitro assays,the effects of young and elderly CD1 1b+ GR 1+ MDSCs on the proliferation of T cells were determined by Brdu Elisa.Transwell co-culture and real-timePCR were used to identify the mechanisms of different immune suppressive functions of CD11b+GR 1+ MDSCs sorted from young mice and elderly mice.Results Compared with young MDSCs,elderly MDSCs could evidently suppress the proliferation of T cells (t=8.67,P<0.001),and this function could be reversed by trans-well co-culture (t=6.93,P<0.001).The results of realtime PCR revealed that,compared with young MDSCs,elderly MDSCs expressed higher levels of arginase-1 (ARG-1),inducible nitric oxide synthase (iNOS),reactive oxygen species (ROS),interleukin 10 (IL-10),IL13 and transforming growth factor (TGF)-β (t=9.04,4.86,7.04,6.92,4.51,5.46,respectively,P<0.05 or P<0.01).Conclusions CD11b+GR-1+MDSCs sorted from healthy elderly mice can evidently suppress the proliferation of T cells through cell-cell contact and secretion of suppressive medium.

ObjectiveTo determine the static equilibrium of elderly individuals over the age of 60 and the correlation to the age. Methods142 elderly subjects (60~95 years old) were divided into 7 groups: 60~65 years old group, 66~70 years old group, 71~75 years old group, 76~80 years old group, 81~85 years old group, 86~90 years group, and >90 years old group, 24 cases 18~30 years old as the control. The static equilibrium was examined by measuring the stability index (ST) and the spectrum analysis of postural sway under following 4 conditions: standing on solid surface with eyes open (NO),standing on solid surface with eyes closed (NC), standing on pillows with eyes open (PO), and standing on pillows with eyes closed (PC) using Tetrax Balance System. ResultsThe ST and the intensity of postural sway increased in the elderly group compared with the control group. NO: there were significant differences (P<0.01) in ST, F1, F4, F6, F8 among the 81~85 years group, 86~90 years old group, >90 years old group and the control group. NC: there were significant differences (P<0.01) in ST, F1, F4 among all the elderly groups and the control group, and in F6, F8 among the >66 years groups and the control group(P<0.05). PO: there were significant differences (P<0.01) in ST, F4, F6 among the >66 years old groups and the control group, and in F1, F8 among the >71 years old groups and the control group(P<0.05). PC: there were significant differences (P<0.01) in ST, F4 among all the elderly groups and the control group, in F6 among the >66 years groups and the control group, in F8 among the >76 years old groups and the control group, and in F1 among the >80 years old groups and the control group(P<0.05). The ST distributed as NOP<0.01). There were similar changes in the intensity of postural sway of F1, F4, F6, F8 bands. ConclusionThere is the significant decline of the static equilibrium in the subjects aged 80 or over and no significant decline of the static equilibrium in the subjects aged 60~80 whose compensation in the static balance may decrease.

OBJECTIVETo improve the water solubility and biological activity of neoligans (magnolol and honokiol) and test the antitumor activity of the modified compounds.
METHODSThe glycosylated products of magnolol and honokiol were obtained by enzymatic synthesis using a UDP-glycosyltransferase (YjiC) from Bacillus. The products were characterized by high-performance liquid chromatography (HPLC), liquid chromatography-mass spectrometry (LC-MS), and nuclear magnetic resonance (NMR) analysis. MTT assay was used to detect the growth inhibition of 4 human cancer cell lines induced by the compounds.
RESULTSWe obtained two glucosides of neolignans (magnolol and honokiol) for the first time by enzymatic synthesis using a UDP-glycosyltransferase. Based on the spectroscopic data, the glucosides were identified as magnolol-2- O-β-D-glucopyranoside (1) and honokiol-4'-O-β-D-glucopyranoside (2). Compounds 1-4 exhibited moderate anti-proliferative activities against the 4 human cancer cell lines, with IC50 values ranging from 9.41 to 111.21 µmol/L.
CONCLUSIONThe glycoslated products show enhanced water solubility and drug sensitivity against SMMC7721 cells, suggesting their value as potential therapeutic drugs.

Objective:
To investigate the safety and effectiveness of radiofrequency ablation (RFA) for selective fetal reduction in complex multiple pregnancies and analyze factors affecting perinatal outcomes.
Methods:
This was a retrospective case series of 156 patients undergoing selective fetal reduction by RFA in Provincial Hospital Affiliated to Shandong University from July 22th, 2011 to September 12th, 2018. They were divided into five groups according to surgical indications, including 46 cases in the monochorionic twins discordant for fetal anomalies group, 42 cases in the multiple pregnancies for reducing fetal numbers group, 40 cases in the twin to twin transfusion syndrome (TTTS) group, 24 cases in the selective intrauterine growth restriction (sIUGR) group and 4 cases in the twin reversed arterial perfusion sequence (TRAPS) group. According to the gestational age at surgery, patients were divided into two groups: the gestational age at surgery <20 weeks group (75 cases) and the gestational age at surgery≥20 weeks group (81 cases). According to the cycles of RFA required for surgery, patients were divided into two groups: one cycle group (124 cases) and ≥2 cycles group (32 cases). Basic information of patients, surgical process, postoperative complications and pregnancy outcomes were recorded. The growth and development of survival newborns were also followed up. Factors affecting perinatal outcomes were analyzed.
Results:
(1) The median gestational age at procedure of 156 patients was 20 weeks (14+5- 29+1 weeks). The median cycles of RFA was 1 cycle (1-3 cycles), of which one cycle accounted for 79.5% (124/156). (2) Eleven (7.1%, 11/156) patients experienced intrauterine fetal death, 27 (17.3%, 27/156) patients miscarried, and the overall survival rate was 75.6% (118/156). Premature birth rate before 34 weeks was 19.5% (23/118). There were 129 neonates. The median gestational age at delivery was 37+3 weeks (28+2- 41+1 weeks) with a mean birth weight of (2 657±700) g. (3) Analysis of pregnancy outcomes based on surgical indications found that, the gestational age at delivery [38 weeks (30+1-41+1 weeks), 36+4 weeks (29- 39 weeks), 36+4 weeks (28+2-39+5 weeks), 38 weeks (31-39+6 weeks), 38+3 weeks (30+4-38+4 weeks)] and neonatal birth weight [(2 820±671), (2 435±416), (2 497±843), (2 998±718), (2 517±1 087) g] were significantly different among fetal anomalies group, reducing fetal numbers group, TTTS group, sIUGR group and TRAPS group, respectively (all

Photoreactive heparin was synthesized by reaction of 4-azidoaniline and heparin. An organic layer was introduced on the surface of Ti-O by 3-aminopropylphosphonic acid assembling, and then the modified heparin was immobilized on the surface by UV irradiation. Water contact angle was used to characterize the hydrophilicity, quantitive assay was done by azure staining methods, and blood compatibility was evaluated by platelet adhesion experiment. Water contact angle of heparinized surface was smaller than that of Ti-O film, which indicated more hydrophilic property of heparinized surface. The surface density of heparin increased with the prolonging of irradiation time and the density was 2.1 microg/cm2 when irradiated for 300s. It showed the heparinized surface was effective in resisting platelets from adhesion and aggregation.
