OBJECTIVE: To evaluate the spontaneous brain activity alterations in liver transplantation (LT) recipients using resting-state functional MRI. MATERIALS AND METHODS: Twenty cirrhotic patients as transplant candidates and 25 healthy controls (HCs) were included in this study. All patients repeated the MRI study one month after LT. Amplitude of low-frequency fluctuation (ALFF) values were compared between cirrhotic patients (both pre- and post-LT) and HCs as well as between the pre- and post-LT groups. The relationship between ALFF changes and venous blood ammonia levels and neuropsychological tests were investigated using Pearson's correlation analysis. RESULTS: In the cirrhotic patients, decreased ALFF in the vision-related regions (left lingual gyrus and calcarine), sensorimotor-related regions (left postcentral gyrus and middle cingulate cortex), and the default-mode network (bilateral precuneus and left inferior parietal lobule) were restored, and the increased ALFF in the temporal and frontal lobe improved in the early period after LT. The ALFF decreases persisted in the right supplementary motor area, inferior parietal lobule, and calcarine. The ALFF changes in the right precuneus were negatively correlated with changes in number connection test-A scores (r = 0.507, p < 0.05). CONCLUSION: LT improved spontaneous brain activity and the results for associated cognition tests. However, decreased ALFF in some areas persisted, and new-onset abnormal ALFF were possible, indicating that complete cognitive function recovery may need more time.

OBJECTIVETo investigate polymorphisms of killer cell immunoglobulin-like receptor gene (KIR) in renal transplant recipients from southern Zhejiang.

METHODSKIR genotypes were analyzed by PCR-SSP in 416 renal transplant recipients, and the genotype frequencies were compared with populations from Eastern China and worldwide.

RESULTSAll 16 known KIR genes were detected in the renal transplant recipients, and KIR2DL4, 3DL2-3, 3PD1 were found in all. As a pseudogene, 2DP1 has a high genotype frequency (99%). The frequencies of KIR2DL1, 2DL3, 3DL1, 2DS4 have ranged from 92.1% to 98.8%. Compared with 11 groups in Eastern China and other countries, the KIR2DL2 phenotype frequency was higher (34.6%) than those of Shanghai, Zhejiang and Jiangsu populations (P<0.05). Among 41 genotypes, three have not been reported previously. The most common genotype was AA1, with a frequency of 43.51%, which was significantly lower than those of Jiangsu and Northern Zhejiang.

CONCLUSIONRenal transplant recipients from southern Zhejiang share similar features with Eastern China Han population with regard to KIR polymorphisms, but also have unique frequencies for KIR genotypes.

OBJECTIVETo investigate the effect of lithium chloride (LiCl) on cell cycle of HK-2 cells and explore the possible pathways involved.

METHODSHK-2 cells were treated with LiCl at different concentrations (5, 12.5, 20, and 25 mmol/L) for 12, 24, 48, or 72 h, and the changes in cell cycle and viability were detected using flow cytometry and CCK-8 assay, respectively. Western blotting was used to analyze the changes in the expressions of cyclin B1 and CDK1 (the two G2 phase-related proteins) and those of AKT/GSK-3β signaling pathway-related proteins in the treated cells.

RESULTSLiCl treatment time- and concentration-dependently increased HK-2 cell percentage in G2 phase and decreased the cell vitality. The expressions of cyclin B1, CDK1, p-GSK-3β, and β-catenin increased and the expression of p-AKT decreased significantly in the cells as LiCl treatment time and concentration increased.

CONCLUSIONLiCl may cause HK-2 cell cycle arrest in G2 phase through activation of the AKT/GSK-3β signaling pathway.

OBJECTIVETo study the pathogen distribution and risk factors of nosocomial infection in very preterm infants, as well as the risk of adverse outcomes.

METHODSA retrospective analysis was performed for the clinical data of 111 very preterm infants who were born between January and December, 2016 and had a gestational age of <32 weeks and a birth weight of <1 500 g. According to the presence or absence of nosocomial infection after 72 hours of hospitalization, the infants were divided into infection group and non-infection group. The infection group was analyzed in terms of pathogenic bacteria which caused infection and their drug sensitivity. A multivariate logistic regression analysis was used to investigate the potential risk factors and risk of adverse outcomes of nosocomial infection in very preterm infants.

RESULTSGram-negative bacteria were the main pathogens for nosocomial infection in very preterm infants and accounted for 54%, among which Pseudomonas aeruginosa was the most common one; the following pathogens were fungi (41%), among which Candida albicans was the most common one. The drug sensitivity test showed that Gram-negative bacteria were highly resistant to β-lactam and carbapenems and highly sensitive to quinolones, while fungi had low sensitivity to itraconazole and high sensitivity to 5-fluorocytosine and amphotericin B. Early-onset sepsis, duration of peripherally inserted central catheter, steroid exposure, and duration of parenteral nutrition were risk factors for nosocomial infection in very preterm infants (P<0.05). Compared with the non-infection group, the infection group had significantly higher risks of pulmonary complications (P<0.05), as well as a significantly longer length of hospital stay and a significantly higher hospital cost (P<0.001).

CONCLUSIONSNosocomial infection in very preterm infants is affected by various factors and may increase the risk of adverse outcomes. In clinical practice, reasonable preventive and treatment measures should be taken with reference to drug sensitivity, in order to improve the prognosis of very premature infants.

Current studies have demonstrated that SLC38A1 proteins play a causal role in neoplastic cell transformation.The twofold aim of this study was to provide insight into whether a variance in the expression of SLC38A1 exists between human colorectal cancer and healthy human tissues and to determine how silencing or overexpressing the SLC38A1 gene could affect the proliferation,viability and migration of colorectal cancer cells.Immunohistochemical staining was used to analyze the expression of SLC38A1 in colorectal cancer tissues and adjacent normal mucosa in 77 patients who underwent surgical resection.The expression of SLC38A1 in colorectal cancer tissues and cell lines was detected using RT-PCR and Western blotting.Two colorectal cancer cell lines SW480 and HCT116 were used to examine whether silencing SLC38A1 with siRNA and overexpressing SLC38A1 with shRNA could affect cell viability and migration.As a result,the SLC38A1 protein was very low or undetectable in the normal colon mucosa.In contrast,strong staining of SLC38A1 protein was found in the cytoplasm in 79.2％ colorectal cancer samples.More pronounced SLC38A1 expression in colorectal cancer tissues was significantly associated with tumor node metastasis (TNM) stage.Inhibition of SLC38A1 reduced tumour growth and suppressed proliferation and migration of SW480 cells.In contrast,overexpression of SLC38A1 had the opposite effects on HCT116 cells.S LC38A1 is overexpressed in colorectal cancer,which suggests that it is associated with tumour progression.These results encourage the exploration of SLC38A1 as a target for intervention in colorectal cancer.
