Objective To observe the impact of cold circulation liquid temperature on ablation focus morphology of microwave ablation(MWA)for in vitro porcine liver tissue.Methods Twenty in vitro fresh porcine liver blocks were randomly divided into ice water circulation group(group A)and normal temperature circulation group(group B),respectively.Ten target ablations in each subgroups in group A and group B,i.e.A1 and B1(50 W,1 min),A2 and B2(50 W,5 min),A3 and B3(60 W,1 min),A4 and B4(60 W,5 min),A5 and B5(70 W,1 min)as well as A6 and B6(70 W,5 min)subgroups were performed using different ablation power(50,60,70 W)and ablation time(1,5 min),respectively.Then the morphology indexes of ablation foci,including longitudinal diameter(LD),transverse diameter(TD),roundness index(RI)and volume(V)were compared between subgroups in group A and B,also among subgroups within group A and B.Results Under the same ablation power and time,LD of ablation foci in subgroups of group A were all smaller than those of group B(all P＜0.05).Significant differences of RI of ablation foci were found between A1 and B1,A2 and B2,A4 and B4,A5 and B5 as well as A6 and B6 subgroups(all P＜0.05),but not between A3 and B3 subgroups(P＞0.05).However,the main effect of cold circulation liquid temperature on ablation focus TD(F=1.125)nor V(F=3.332)was not significant(both P≥0.05).Under the same cold circulation liquid temperature,significant differences of the morphology indexes of ablation foci were detected between A1 and A2,A3 and A4 as well as A5 and A6 subgroups,also between corresponding subgroups in group B(all P＜0.05).Conclusion During MWA for in vitro porcine liver tissue under constant ablation power and time,taken ice water as the cold circulation liquid was benefit to ablation focus shaped spherically.With the extension of ablation time,the larger the ablation focus,the higher the RI.

In the context of non-alcoholic fatty liver disease (NAFLD), characterized by dysregulated lipid metabolism in hepatocytes, the quest for safe and effective therapeutics targeting lipid metabolism has gained paramount importance. Sanhuang Xiexin Tang (SXT) and Baihu Tang (BHT) have emerged as prominent candidates for treating metabolic disorders. SXT combined with BHT plus Cangzhu (SBC) has been used clinically for Weihuochisheng obese patients. This retrospective analysis focused on assessing the anti-obesity effects of SBC in Weihuochisheng obese patients. We observed significant reductions in body weight and hepatic lipid content among obese patients following SBC treatment. To gain further insights, we investigated the effects and underlying mechanisms of SBC in HFD-fed mice. The results demonstrated that SBC treatment mitigated body weight gain and hepatic lipid accumulation in HFD-fed mice. Pharmacological network analysis suggested that SBC may affect lipid metabolism, mitochondria, inflammation, and apoptosis-a hypothesis supported by the hepatic transcriptomic analysis in HFD-fed mice treated with SBC. Notably, SBC treatment was associated with enhanced hepatic mitochondrial biogenesis and the inhibition of the c-Jun N-terminal kinase (JNK)/nuclear factor-kappa B (NF-κB) and extracellular signal-regulated kinase (ERK)/NF-κB pathways. In conclusion, SBC treatment alleviates NAFLD in both obese patients and mouse models by improving lipid metabolism, potentially through enhancing mitochondrial biogenesis. These effects, in turn, ameliorate inflammation in hepatocytes.

Objective To investigate the effect of comprehensive nursing intervention and evaluate its role in the entire clinical course of in the treatment of children with severe burns. Methods A total of 60 children with 1-5 years old with clinical diagnosis of severe burns were randomly divided into experimental group and control group by random digits table method, 30 cases in each group. The control group received routine burn care. The experimental group received comprehensive nursing interventions on the basis of routine burn care and the intervention time covered the entire course of treatment. During hospitalization, the recovery and family social system were evaluated by anxiety scales and social support scales combined with the cure rate and hospitalization of children. Results Before intervention, the score of Anxiety Rating Scale was high in both groups of families, while Social Support Scale was lower, the difference was not statistically significant between the two groups (P>0.05). After intervention, the score of Anxiety Rating Scale and was Social Support Scale were (52.31±7.81), (31.52± 5.48)points in the experimental group, and (62.51 ± 6.52), (23.62 ± 5.62) points in the control group, and there were significant differences (t=5.491 3, 5.512 5, P<0.01). The length of stay was (18.34±3.58) d in the experimental group, and (21.82 ± 4.23) d in the control group, and there was significant difference(t=3.439 6, P<0.05). The cure rate was 93.33%(28/30) in the experimental group, and 56.67%(17/30) in the control group, and there was significant difference(χ2=10.755 6, P<0.05). Conclusions The comprehensive nursing intervention can provide comprehensive refinement of the overall care in children and their families, promote physical and psychological rehabilitation of children with severe burns, and repair their family and social support systems. The comprehensive nursing intervention has far-reaching implications for the rehabilitation of children with severe burns.

BACKGROUNDPreeclampsia, characterized by hypertension and proteinuria, is a multifactorial disease associated with shallow invasion of trophoblast cells and inadequate spiral artery remodeling. Trophoblast and tumor cells have similar invasion mechanism. Prostasin is closely related to tumor development, invasion and metastasis and influences blood pressure through activating epithelial sodium channel. The effect of prostasin on the pathogenesis of preeclampsia remains unclear. This study investigated the association of prostasin gene at rs12597511 with severe preeclampsia.

METHODSA single nucleotide polymorphism, rs12597511, was tested with polymerase chain reaction and restrictionfragment length polymorphism analyses in 179 severe preeclampsia patients and 222 normal pregnant women.

RESULTSThe frequencies of TC + CC genotypes were significantly higher in severe preeclampsia group compared with in control group (the adjusted odds ratio was 2.030, 95% confidence interval 1.195-3.449, P = 0.009). The C allele of rs12597511 was present significantly more often among women with severe preeclampsia (P = 0.001). Genotyping analysis showed that the C allele of rs12597511 could confer a risk for severe preeclampsia.

CONCLUSIONThe higher frequency of C allele of prostasin gene at rs12597511 is associated with severe preeclampsia.

Based on thermodynamic principle, the critical relative humidity of electrolytes is closely related to their solubility. The authors explored the relationship theoretically and calculated critical relative humidity of 21 electrolytes from their solubility in the light of Raoult's law and extended Wilson model. The results indicate that the critical relative humidity values calculated by Raoult's law can not accord with the reported ones and there is a systematic error in the high concentration range; while these calculated by extended Wilson model are comparable to the reported ones.
