BACKGROUND:Research on liver transplantation has not just focused on survival rate and survival time, and the quality of life has become a new field of study. However, it is stil a blank about the quality of life of liver transplant recipients in Xinjiang. OBJECTIVE:To investigate the quality of life of liver transplant recipients in Xinjiang and to explore the main risk factors for the quality of life in patients. METHODS: A Chinese version of the SF-36 health survey was used to retrospectively evaluate the quality of life of liver transplant recipients in Xinjiang. RESULTS AND CONCLUSION:The scores of al eight dimensions in the patients with liver transplantation ranged from 60.6±18.7 to 93.9±22.1. Primary diseases, operation method, marital status, level of education, occupation, gender and age could influence the quality of life of the liver transplant recipients, but nation, income and the way of medical insurance had no significant effect on the quality of life. These findings indicate that there is no obvious difference in the quality of life between liver transplant recipients and normal population, and the scores in six dimensions are higher in the liver transplant recipients than normal population, which is further confirmed that liver transplantation is an effective way for treatment of advanced liver disease.

OBJECTIVETo investigate the anxiety disorders and influence factors that occur in adolescent patients with cleft lip and palate and to provide theoretical foundation for mental intervention.

METHODSA total of 120 adolescent patients with cleft lip and palate were investigated using a general information questionnaire, the self-rating anxiety scale, and the social support rating scale (SSRS). The influence factors of anxiety disorders were analyzed.

RESULTSThe effective questionnaires were 119. The occurrence rate of anxiety disorder in adolescent patients was 49.6% (59/119), and the occurrence rates of mild, moderate, and severe anxieties were 41.2% (49/119), 7.6% (9/119), and 0.8% (1/119), respectively. The gender, residential area, disease category, family status (one child or no children), and incidence rate of anxiety disorder in patients were statistically different (P<0.05). The SSRS scores of patients with anxiety disorder were lower than those of patients without anxiety disorder (P<0.05). Multiple regression analysis showed that gender and social support were predictive factors of the occurrence of anxiety disorder (R=0.318).

CONCLUSIONA high anxiety disorder rate occurred in adolescent patients with cleft lip and palate. dender and social support were important influencing factors for anxiety disorder. In the after-mental intervention, considerable attention should be given to the anxiety disorders of patients and improve their mental health.

Flow cytometry data indicated that berberine decreased M 1 type macrophages and increased M 2 type macrophages in liver tissue .The ratio of M1/M2 was significantly decreased in berberine and rosiglitazone treated group ( P <0.01 ) .Conclusion Berberine may improve the hepatic pathological process in MCD diet induced NASH model possibly through modulating macrophage phenotype transformation , i.e.The ratio of M2 type is more than M1 type in hepatic tissue , and increasing anti-inflammatory cytokines .

To optimize the immunization strategy against HIV-1, a DNA vaccine was combined with a recombinant vaccinia virus (rTV) vaccine and a protein vaccine. Immune responses against HIV-1 were detected in 30 female guinea pigs divided into six groups. Three groups of guinea pigs were primed with HIV-1 DNA vaccine three times, boosted with rTV at week 14, and then boosted with gp140 protein at intervals of 4, 8 or 12 weeks. Simultaneously, the other three groups of animals were primed with rTV vaccine once, and then boosted with gp140 after 4, 8 or 12 weeks. The HIV-1 specific binding antibody and neutralizing antibody, in addition to the relative affinity of these antibodies, were detected at different time points after the final administration of vaccine in each group. The DNA-rTV-gp140 immune regimen induced higher titers and affinity levels of HIV-1 gp120/gp140 antibodies and stronger V1V2-gp70 antibodies than the rTV-gp140 regimen. In the guinea pigs that underwent the DNA-rTV-gp140 regimen, the highest V1V2-gp70 antibody was induced in the 12-week-interval group. However, the avidity of antibodies was improved in the 4-week-interval group. Using the rTV-gp140 immunization strategy, guinea pigs boosted at 8 or 12 weeks after rTV priming elicited stronger humoral responses than those boosted at 4 weeks after priming. In conclusion, this study shows that the immunization strategy of HIV-1 DNA vaccine priming, followed by rTV and protein vaccine boosting, could strengthen the humoral response against HIV-1. Longer intervals were better to induce V1V2-gp70-specific antibodies, while shorter intervals were more beneficial to enhance the avidity of antibodies.

Methods: In 20 recruited healthy subjects, the change of the temperature-related brain regions induced by mild moxibustion from different distances at Zusanli (ST 36) was observed by functional magnetic resonance imaging (fMRI). Results: In comparison of the values in amplitude of low-frequency fluctuation (fALFF) during and before moxibustion, it has been found that in moxibustion of 2 cm distance, fALFF value increased in the brain regions of the left anterior cingulated cortex and lateral surrounding cerebral regions, and fALFF value decreased in the cerebral regions of the peripheral cortex of the calcarine fissure; in moxibustion of 3 cm distance, fALFF value increased in the brain regions of the right and medial side and paracingulated gyrus, and fALFF value decreased in the cerebral zone of the left middle temporal gyrus; in moxibustion of 4 cm distance, fALFF value increased in the brain regions of the right and medial and paracingulated gyrus; and in moxibustion of 5 cm distance, fALFF value increased in the brain regions of the left hippocampus. In comparison of the value of regional homogeneity (ReHo), it has been found that in moxibustion of 2 cm distance, ReHo value increased in the cerebral zone of the posterior lobe of the right cerebellum, and ReHo value decreased in the cerebral zone of the right occipital lobe; in moxibustion of 3 cm distance, ReHo value increased in the brain regions of the left cerebellar posterior lobe and left frontal lobe, and ReHo value decreased in the cerebral zone of the right inferior temporal gyrus; in moxibustion of 4 cm distance, ReHo value increased in the brain regions of the right superior frontal gyrus and ReHo value decreased in the brain regions of the right parietal lobe and angular gyrus; in moxibustion of 5 cm distance, ReHo value increased in the cerebral zone of the right frontal lobe and ReHo value decreased in the cerebral zone of the right brainstem. Conclusion: In moxibustion of 3 cm distance, the changes in the brain regions basically conform to the transmission route of body trunk temperature.

OBJECTIVETo investigate the effect of miRNA-101 on the expression of the enhancer of zeste homolog 2 (EXH2) in human androgen-independent prostated cancer LNCaP cells.

METHODSWe divided LNCaP cells into a blank control, a negative control, and a miRNA-l01 transfection group, constructed the vector by transfecting synthetic miRNA-101 mimics into the LNCaP cells, and evaluated the efficiency of transfection by fluorescence microscopy. Then we determined the expression level of EZH2 mRNA by qRT-PCR in the three groups of cells and that of the EZH2 protein in the negative control and transfection groups by Western blot.

RESULTSGreen fluorescence signals were observed in over 70% of the LNCaP cells in the transfection group after 24 hours of transfection. At 72 hours, the expression of miRNA-101 was significantly upregulated in the transfected cells (P < 0.01), that of EZH2 mRNA was remarkably lower in the transfection group (0.01 ± 0.10) than in the blank control (0.95 ± 0.40) and negative control (0.86 ± 0.30) groups (both P < 0.01), and that of the EZH2 protein was increased in the negative control but decreased in the transfection group with the extension of culture time.

CONCLUSIONmiRNA-101, with its inhibitory effect on the expression of EZH2 in LNCaP cells, is a potential biotherapeutic for prostate cancer.
