Metabolic dysfunction-associated steatotic liver disease (MASLD) is characterized by abnormal lipid deposition in the liver and its mechanism is closely related to insulin resistance, lipid metabolism disorders, oxidative stress, and abnormalities of the gut-liver axis. Currently, there is no effective treatment for this disease. Silent information regulator 2 (SIRT2) is a nicotinamide adenine dinucleotide (NAD⁺)-dependent deacetylase which performs various pathophysiological functions by interacting with different substrates. For example, it is involved in improving metabolic homeostasis, alleviating liver inflammation, promoting liver regeneration, and delaying the progression of MASLD. In this paper, we present a review of the mechanism of action of SIRT2 in MASLD to analyze the potential value of SIRT2 as a therapeutic target in MASLD.

Objective To explore the value of MRI histogram analysis in the risk assessment of medulloblastoma recur rence.Methods The data of 28 patients pathologically confirmed of medulloblastoma was analyzed retrospectively.All patients were divided into recurrent group and the non recurrent group (each n=14).The ROIs were drawn on the maximum level of enhanced MR sagittal images,and the histogram analysis were performed using the software named Mazda.The statistical analysis was performed on the histogram parameters to find out the different characteristics between the two groups,and the ROC curve was drawn to evaluate its diagnostic efficacy for recurrence of medulloblastoma.Results In all of the 9 parameters which are extracted from histogram,kurtosis had statistical significance between the 2 groups (P=0.018).The area under the ROC curve was 0.776 (P=0.018),and the sensitivity and specificity of kurtosis in the risk assessment of medulloblastoma recurrence were 64.3％ and 71.4％,respectively.Conclusion MRI histogram analysis can be an important method to assess the risk of medulloblastoma recurrence.

Objective To analyze the relationships between the drinking water fluoride and bone mineral density (BMD), and serum osteocalcin (BGP) and to explore the BMD and serum BGP as significant early screening biomarkers for fluorosis especially for early bone damage in endemic fluorosis areas. Methods Wamiao (severe endemic fluorosis area, as fluoride exposed group) and Xinhuai (non endemic fluorosis area, as control group) Village were selected in 2006. One hundred and fouty-six objects were chosen from 2 villages (103 in Wamiao, 43 in Xinhuai). The sex, age, body height, body weight, drinking water fluoride in each object's household well, BMD, and serum BGP were investigated, and the dose-response relationships were analyzed between the drinking water fluoride and BMD, and serum BGP. CurveExpert 1.3 Software was used to fit the dose-response relationships between the rate of abnormal BMD, the rate of abnormal serum BGP, and the drinking water fluoride. Results The levels of drinking water fluoride in males' and females' families in fluoride exposed group were [(2.38±0.68), (2.62±0.91 )mg/L] significant higher than that in control group [(0.35±0.08), (0.36±0.07)mg/L], the difference being statistically significant(t values were 14.27 and 11.08,and P<0.01, respectively). BMD in males in fluoride exposed group [(0.78±0.07)g/cm2] was significant lower than that in control group[(0.83±0.08)g/cm2], the difference being statistically significant (t=2.37,P<0.05). Serum BGP in males and females in fluoride exposed group [(4.17±0.67), (4.11±0.57) μg/L] were significant higher than that in control group [(1.48±0.40), (1.44±0.39)μg/L], the difference being statistically significant (t values were 17.64 and 19.40, and P<0.01, respectively]. BMD in the group with drinking water fluoride≥2.92 mg/L[(0.66±0.15 )g/cm2] was significant lower than that in the group with drinking water fluoride<0.42 mg/L [(0.76±0.12)g/cm2], the difference being statistically significant (P<0.01). The levels of serum BGP in the groups with the drinking water 0.42-,2.05-, ≥.92 mg/L[(3.83±1.07), (4.22±0.72), (3.99±0.63) μg/L] were significant higher than that in the group with the drinking water<0.42 mg/L [(1.44±0.37) μg/L], the difference being statistically significant (P<0.01). The equation for the dose-response relationship between the drinking water fluoride and the rate of abnormal BMD was y=(0.284-0.058x)-1.260, r=0.999 94; and y=100.05/(1+78.62e-4.5x), r=0.999 99 for the drinking water fluoride and the rate of abnormal serum BGP. Conclusions There were significant dose-response relationships between drinking water fluoride and BMD and serum BGP. It indicated that BMD and BGP might be considered as early screening biomarkers for endemic fluorosis, especially for the bone damage.

OBJECTIVETo compare the efficacy of nasal synchronized intermittent positive pressure ventilation (NSIPPV) and nasal continuous positive airway pressure ventilation (NCPAP) for the treatment of apnea in preterm infants.

METHODSEighty preterm infants with apnea from August 2010 to January 2011 were randomly administered with NSIPPV and NCPAP (n=40 each).The blood gas results before and 2 hrs after ventilation, time of using ventilator, therapeutic efficacy and complications were compared between the two groups.

RESULTSThere were no significant differences in the blood gas results between the two groups before ventilation. The blood gas results (pH, PO2, PCO2) in the NSIPPV group were better than those in the NCPAP group 2 hrs after ventilation. The time of using ventilator in the NSIPPV group was shorter than that in the NCPAP group (50±9 h vs 91±11 h; P<0.01). There were no significant differences in the total effective rate between the NSIPPV and the NCPAP groups (95% vs 85%; P>0.05). The proportion of ventilator weaning within 3 days in the NSIPPV group (23/40) was higher than that in the NCPAP group (14/40) (P<0.05). The incidence of complications in the NSIPPV group was not different from that in the NCPAP group (22% vs 25%).

CONCLUSIONSNSIPPV appears to be superior to NCPAP for the treatment of apnea in preterm infants.
