Objective To investigate the etiology and treatment of severe infection after ureteroscopic holmium laser lithotripsy. Methods Seven cases (2 men and 5 women) of severe infection after holmium laser lithotripsy under ureteroscope were treated.Their mean age was 44 years (range,37-56 years). The patients were characterized by a temperature over 39 ℃,a heart rate over 110 BPM,and a blood pressure below 80/50 mm Hg (1 mm Hg=0.133 kPa) within 1-12 hours after the operation.The diagnosis of septic shock caused by gram negative bacteria was suggested by the clinical manifestation and the urine culture. Anti-shock therapy was conducted with rapid supplement of colloidal and crystalloid solution of 3000-4000 ml.The vasoactive drugs,dopamine (2-5 ?g/kg per minute) or norepinephrine (4-8 ?g/kg per minute) were used for the establishment of stable circulation,and the third generation cephalosporins for the control of infection empirically.Low dose corticosteroids (dexamethasone,10-20 mg) were administered if the patients had adrenocortical insufficiency or significant intoxication. Results All patients were treated successfully within 8 to 48 hours,then the hypertensors were gradually stopped.Their temperature and blood routine tests returned to normal 3 days later.. Conclusions The causes of severe infection after holmium laser lithotripsy under ureteroscope are preoperative urinary tract infection,high perfusion pressure or postoperative urinary tract obstruction.Peri operative anti infection and appropriate operation skill can effectively prevent the infection.

Objective To explore the effect and mechanism of Kuntai Capsule (KC) on premature ovarian failure in rats.Methods Totally 40 SD female rats were randomly divided into four groups:control group,model group,Kuntai Capsule (KC) group and conjugated estrogens tablets (CET) group.The premature ovarian failure model in rats was made by ig administration of 75 mg/kg tripterygium.After the model was established,rats were continually treated with 0.6 and 0.625 g/kg of KC and CET respectively by ig administration for 36 d.HE staining was used to observe the morphology of ovary and count the number of follicle.The enzyme-linked immunosorbent assay (Elisa) method was used for the detection of follicle stimulating hormone (FSH),luteinizing hormone (LH),serum estradiol (E2),and anti-Mueller tube hormone (AMH) level.The real-time fluorescence quantitative PCR (qRT-PCR) method was used to detect the mRNA expression of vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (bFGF).Results Compared with control group,the number of primordial follicles,preantral follicles and antral follicles were significantly reduced,the number of atretic follicles was increased (P ＜ 0.05),E2 and AMH significantly decreased (P ＜ 0.05),FSH and LH levels increased significantly (P ＜ 0.05),and the levels of VEGF and bFGF mRNA in model group were significantly decreased (P ＜ 0.05).Compared with model group,the number of primordial follicles,preantral follicles,and antral follicles were significantly increased,the number of atretic follicles was significantly reduced (P ＜ 0.05),E2 and AMH significantly increased (P ＜ 0.05),FSH and LH levels significantly decreased (P ＜ 0.05),and the levels of VEGF and bFGF mRNA in KC group were significantly increased (P ＜ 0.05).Conclusion By regulating the level of hormone and up-regulating the expression of VEGF and bFGF,KC can repair the damaged ovarian tissue and promote the growth and development of the follicle,so as to inhibit the premature exhaustion of mRNA.

Objective To breed homozygous mice of Treg-Th17 fluorescence double labeling and to investigate the role of Treg-Th17 balance in endotoxemia. Methods Mice of Treg and Th17 fluorescence single labeling were brought from Harvard Medical School,USA and were mated and bred based on the genetic rules.The genomic DNA was extracted from the tails of second generation weaning mice for genotyping by polymerase chain reaction (PCR).Thereafter,the homozygous mice of fluorescence double labeling were selected to have successive inbreeding for three generations and their genotypes and growth status were measured.The endotoxemia model in vivo was duplicated and changes of Treg-Th17 balance were detected by flow cytometry analysis at 24 h and 48 h after endotoxemia. Results Among the seven second generation mice in the first batch,only three (two males and one female) were the wanted homozygotes.Meanwhile,the genotypes of their offsprings for the next three generations were all Foxp3 RFPKI-homo IL-17A GFPKI with normal growing status.As important component of endotoxin,lipopolysaccharide (LPS)could induce significant signal expressions of red fluorescence protein (RFP) and green fluorescence protein (GFP).The ratio of CD8a + Foxp3 +,CD8a + IL-17A +,CD4 + Foxp3 + and CD4 + IL-17A + in the lymphocytes went up significantly in the group of 24 hours of LPS treatment,as compared with the control group (P ＜ 0.01 or P ＜ 0.05 ),while the difference between the control group and the group of 48hours of LPS treatment had no statistical significance (P ＞ 0.05). Conclusion Foxp3 RFPKI-homoIL-17A GFPKI mice have identical genotypes and stable genetic characteristics and is a model animal and novel research platform that can provide real-time monitoring of the changes of Treg-Th17 balance in vivo.The role of T reg-Th17 balance works significantly at 48 hous after the subject is exposed to LPS stimulation,and the roles of CD8a + Foxp3 and CD8a + IL-17A + in Treg-Th17 balance require further investigation.

AIMTo observe the differences of hemodynamics and nitric oxide synthase(NOS) activity of ventricular cardiac muscle in two septic shock models and explore the possible mechanism.

METHODSTwo rat models of septic shock[lipopolysaccharide(LPS)-induced and cecal ligation and puncture (CLP)-induced septic shock] were used. The hemodynamic parameters and nitric oxide synthase activity of ventricular cardiac muscle were measured.

RESULTSThe hemodynamic parameters in CLP-induced model were increased in the early stage and decreased in the late stage while in LPS-induced model the parameters showed the same change of the CLP late stage. Both LPS model and CLP model (late stage) showed significant increase in NOS activity, but there was no difference between the two models. After treatment of the NOS inhibitor N-nitro-L-arginine methyl ester (L-NAME), the parameters of CLP-late stage and LPS model increased significantly. The NOS activity reached the highest level in the CLP-middle stage. The production of nitrite/nitrate decreased significantly in LPS model and CLP model(late stage) after treatment of L-NAME, but the nitrite/nitrate produced by constitutive NOS in LPS model was higher than CLP model(late stage).

CONCLUSIONThe increase of the NOS activity may be the main reason to lead to the depression of the hemodynamic parameters. Inducible NOS may play the leading role in the LPS model while cNOS and iNOS have the same effect in the CLP model.

Objective:To investigate the effect of myeloid-derived suppressor cells (MDSC) on guanylate binding protein 1 (GBP1) in promoting the proliferation of glioma U87 cells and its mechanism.Methods:Glioma cells U87 with GBP1 overexpression (U87-GBP1) and control cells U87-Lacz transfected with empty vector were used as experimental cells. The mRNA and protein expressions of GBP1 and chemokine (C-C motif) ligand 2 (CCL2) in two groups of cells were detected by reverse transcription-quantitative polymerase chain reaction (RT-qPCR), Western blot and enzyme linked immunosorbent assay (ELISA), and the proliferation of U87 cells were detected by CCK-8. CD14 + monocytes and CD3 + T lymphocytes were isolated from peripheral blood of healthy people by immunomagnetic beads. The CD14 + monocytes were treated with culture medium of U87-Lacz cells or U87-GBP1 cells, and then the cells were divided into U87-Lacz culture medium group and U87-GBP1 culture medium group. The proportion of MDSC in CD14 + monocytes was analyzed by flow cytometry. CD14 + monocytes treated by two culture medium groups were cocultured with activated CD3 + T lymphocytes, and flow cytometry was used to detect the proliferation of activated CD3 + T lymphocytes. Monocytes untreated by U87 cells culture medium or activated CD3 + T lymphocytes were used as the control group. CD14 + monocytes were treated with U87-Lacz or U87-GBP1 cell culture medium anti-human CCL2 antibody, which were U87-Lacz+anti-CCL2 culture medium group and U87-GBP1 + anti-CCL2 culture medium group, and the proportion of MDSC in CD14 + monocytes was analyzed by flow cytometry. U87-GBP1 and U87-Lacz cells were inoculated into BALB/c nude mice to cause tumors in the brain. One week later, they were divided into chemokine (C-C motif) receptor 2 (CCR2) inhibitor RS504393 treatment group (U87-Lacz + RS nude mice group and U87-GBP1+RS nude mice group) and untreated control group (U87-Lacz nude mice group and U87-GBP1 nude mice group). After 30 days, the mice were sacrificed and the brain, spleen and bone marrow were isolated. Hematoxylin-eosin (HE) staining was used to observe the transplanted tumors in the brain of nude mice, and the volume of transplanted tumor was calculated, and flow cytometry was used to detect the proportion of MDSC in the tissues. Results:The protein expression of GBP1 in U87-GBP1 cells was significantly higher than that in U87-Lacz cells, but there was no significant difference in cell proliferation level between the two groups in vitro ( P > 0.05). The proportion of MDSC in U87-GBP1 culture medium group was significantly higher than that of U87-Lacz culture medium group [(7.75±0.80)% vs. (4.50±0.08)%], and both groups were higher than that of control group [(2.55±0.31)%)] ( F = 18.27, P = 0.002). The percentage of activated CD3 + T lymphocytes in U87-GBP1 culture medium group was lower than that in U87-Lacz culture medium group [(47.38±0.08)% vs. (61.70±5.05)%, P = 0.040]. The relative expression of CCL2 mRNA in U87-GBP1 cells and the expression level of CCL2 protein in U87-GBP1 cell culture medium [30.66±0.17 and (1 005.00±12.23) ng/L] were higher than those in U87-Lacz cells [1.29±0.15 and (111.60±11.44) ng/L] (both P < 0.01), the proportions of MDSC in U87-Lacz + anti-CCL2 culture medium group and U87-GBP1 + anti-CCL2 culture medium group was lower than those in U87-Lacz culture medium group and U87-GBP1 culture medium group (all P < 0.05). The volume of transplanted brain tumor in U87-GBP1 nude mice group was larger than that in U87-Lacz nude mice group; the volume of transplanted brain tumor in U87-GBP1 + RS nude mice group and U87-Lacz + RS nude mice group increased more slowly than the corresponding nude mice group without treatment, and the differences were statistically significant (all P < 0.05); the proportions of MDSC in transplanted brain tumor, spleen and bone marrow in U87-GBP1 nude mice group were higher than those in U87-Lacz nude mice group, and the proportions of MDSC in each tissue of U87-GBP1 + RS nude mice group and U87-Lacz + RS nude mice group were lower than those in the untreated by RS504393 corresponding nude mice group, and the differences were statistically significant (all P < 0.05). Conclusion:GBP1 might increase the expression of CCL2 in glioma U87 cells and recruit MDSC to form immunosuppression in glioma microenvironment, thus promoting the proliferation of glioma U87 cells in vivo.
