UNLABELLEDThe purpose of this study was to evaluate the effects of cellular immunity activation on P58(+) cells expressing killer cell inhibitory receptor (KIR) and their regulatory function on cellular immunity, and provid theoretical data for preventing graft-vers-host disease (GVHD) in stem cell transplantation therapy. The mononuclear cells from human peripheral blood were incubated with IL-2, Con A and Lipostin (LP) for 72 hours. The KIR expressing cells, P58.1(+) and P58.2(+) cells, were analyzed by flow cytometry. The results showed that the percentages of CD3(+), CD4(+), CD8(+), CD16(+)CD56(+), P58.1(+) and P58.2(+) cells were greatly increased after treated with IL-2, Con A and LP, separately or in combination, and the percentages of above cells in combined treatment groups were higher than those of single stimulated groups, especially the percentage of cells in the IL-2 + LP group was significantly higher than those in IL-2 and LP singly treated groups.

IN CONCLUSIONIL-2, Con A and LP possess the ability to induce the expression of KIR and stimulate proliferation of P58.1(+) and P58.2(+) cells while to activate the celluar immunity response, the expression of P58 gene may be regulated by the activation of cellular immunity.

OBJECTIVETo observe the efficacy of thread-moxa in Zhuang folk medicine (TM) combined with acupuncture and external application drugs for AIDS patients with herpes zoster (AHZ).

METHODSA randomized, controlled clinical trial was conducted in 60 patients with AHZ. They were randomly assigned to the treatment group (treated with TM combined with acupuncture and Jingwanhong Scald Ointment) and the control group (treated with Famciclovir Tablet, nimesulide dispersible tablet, vitamin B1, ribavirin ointment). The treatment course was 14 days for both groups.The clinical efficacy, significant efficiency visual analog scale score (VAS), sleep quality score (QS), the postherpetic neuralgia rate in 1 year after treatment were observed.

RESULTSThe markedly effective rate was significantly higher in the treatment group than in the control group (86.7% vs. 53.3%, P < 0.01). There was no statistical difference in the total effective rate between the two groups (96.7% vs. 80.0%, P > 0.05). The post-treatment VAS, QS, the time for pain disappearance, skin repair, crusting, and 1-year postherpetic neuralgia incidence rate were significantly lower in the treatment group than in the control group (P < 0. 05, P < 0.01).

CONCLUSIONSTM combined with acupuncture and Jingwanhong Scald Ointment was effective for treating AHZ patients. It relieved pain quickly, shortened their course of disease, and improved their quality of sleep.

OBJECTIVETo investigate association of vitamin D receptor (VDR) gene polymorphisms with the susceptibility to chronic periodontitis (CP) of Han Nationality.

METHODSBuccal swabs from 166 patients with severe, moderate and mild CP respectively and 80 matched control individuals were collected. DNA was extracted from these buccal swabs using Chelex-100 method. VDR BsmI, ApaI, TaqI were tested with polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). The distribution of the genotypes and allele frequencies in the patient and control groups were analyzed.

RESULTSThe frequency of VDR ApaI allele A was significantly higher among patients with CP than controls. Frequencies of VDR ApaI allele A were significantly higher in severe CP patients than in moderate CP and mild CP respectively. There was no significant difference in the genotype distribution or the allele frequencies of VDR BsmI and TaqI between the controls and CP patients.

CONCLUSIONSThese data indicate that VDR ApaI allele A may be related to the susceptibility to CP in Han Nationality.

Hepatic venous outflow obstruction is a severe complication after liver transplantation, often occurs after living donor liver transplantation (LDLT). In this article, the clinical and imaging data of two patients with hepatic venous outflow obstruction after LDLT were analyzed retrospectively, and the related literatures were reviewed to explore the diagnosis and the interventional therapy of this complication. Hepatic venous outflow obstruction can be confirmed with percutaneous transhepatic venography. Percutaneous interventional managements, including balloon angioplasty and stent implantation are safe, easy and effective for the treatment of hepatic venous outflow obstruction after adult-to-adult living donor liver transplantation (A-A LDLT).

OBJECTIVETo investigate the impact of intracellular acidification (IA) on drug resistance of leukemia cells with high P-glycoprotein (P-gp) expression, and to provide a new method for the reversing of multidrug resistance (MDR).

METHODSReal-time PCR was used to determine the expression level of mdr1 gene, and the leukemia cells with high P-gp expression were selected. The specific inhibitor of Na+/H+ exchanger 1 and the "high K+" buffer were used to acidify the cells, and the confocal laser microscopy was used to determine the intracellular pH (pHi) and effect of IA on the accumulation of doxorubicin. The MTT method was used to determine the effect of IA on the cell viability. The flow cytometry was used to detect the effect of IA on the P-gp function, and Western blotting was used to determine the effect of IA on the expression of P-gp.

RESULTSThe pHi was decreased to 7.0, and compared with that of control the mdr1 mRNA expression was decreased to (53.2+/-11.0)% after 1 h, and to (16.6+/-7.0)% after 3 h treatment. The P-gp expression was decreased to (56.0+/-9.0)% of the control after 3 h treatment. The accumulation of Rh123 was 71.03+/-0.47 at pHi 7.0, which was increased obviously as compared to the control group 20.07+/-0.39. The increased accumulation of doxorubicin was also observed by confocal laser microscopy.

CONCLUSIONThe expression and function of P-gp on the patients cells are inhibited by IA.

The objective of this study was to compare the effects between knocking-out Sam68 gene by homologous recombination method and silencing the gene by siRNA silencing technique in DT40 cell line. Gene targeting technique was used to isolate Sam68 gene-deleted chicken DT40 cells. Meanwhile, Sam68 gene silencing cells was obtained by using stable expression of siRNA plasmid pSilencer-Sam68. Then, the function of these two cell lines were analyzed by comparing with wild-type DT40 cell line. The results showed that the growth retardation in Sam68 gene knocked-out cell line was observed due to elongation of the G2/M phase, but which could not be found in Sam68 gene silencing cell line. It is concluded that in accordance with study of protein function in living cells, use of gene knockout technique for cell line can provide the experimental results more real than those resulting from gene silence technique.

This study was aimed to investigate whether the inhibition of NHE1 activity and intracellular acidification can reverse resistance of leukemia cells to the imatinib and to explore downstream signal molecule networks of BCR/ABL in the cells of chronic myelocytic leukemia (CML) patients. The mRNA and protein expression of P-glycoprotein (Pgp) and the drug accumulation were assayed after acidifying the primary leukemia cells of patients or K562/DOX and K562/G01 cells. The effects of intracellular acidification of primary leukemia cells on the phosphorylation level changes of ERK1/2 and p38 MAPK were analyzed by Western blot. The results showed that the intracellular concentration of drugs in the advanced patients increased and the sensitivity of K562/DOX and K562/G01 cells to imatinib was enhanced after intracellular acidification or treatment with NHE1 inhibitor cariporide. With downregulation of intracellular pH, the phosphorylation of p38 MAPK decreased in advanced patients and the phosphorylation of ERK1/2 increased within 3 min and then decreased after 30 min. SB203580, the specific inhibitor of p38 MAPK, displayed a synergistic effect with the inhibitor of NHE1 to downregulate the mRNA and protein expression of Pgp. It is concluded that the inhibiton of NHE1 can significantly decrease the protein expression of Pgp in K562/DOX and K562/G01 cells, increase the accumulation of Rhodamine123 and doxorubicin in the cells of advanced patients and enhance the sensitivity of cells to imatinib in which the p38 MAPK signal transduction pathways involves.

OBJECTIVETo apply an orthogonal design optimization strategy to a mouse model of acute liver failure induced by D-galactosamine (D-GalN) and lipopolysaccharide (LPS) exposure.

METHODSA four-level orthogonal array design (L16(45)) was constructed to test factors with potential impact on successful establishment of the model (D-GalN and LPS dosages, and dilution rate of the D-GalN/LPS mixture). The mortality rate of mice within 24 hours of D-GalN/LPS administration was determined by the Kaplan-Meier method. The model outcome was verified by changes in serum alanine transferase level, liver histology, and hepatocyte apoptosis.

RESULTSThe orthogonal array identified the optimal model technique as intraperitoneal injection of a combination of D-GalN and LPS at dosages of 350 mg/kg and 30 mug/kg, respectively, and using a dilution rate of 3. The dosages tested had no effect on survival. The typical signs of liver failure appeared at 6 hrs after administration of the D-GalN/LPS combination.

CONCLUSIONThe orthogonal design optimization strategy provided a procedure for establishing a mouse model of acute liver failure induced by D-GalN and LPS that showed appropriate disease outcome and survival, and which will serve to improve future experimental research of acute liver failure.
