The peroxisome proliferator-activated receptor gamma(peroxisome proliferator-activated receptor gamma,coactivator 1 beta,PPARGC1B)gene is an intranuclear receptor transcription fac-tor responsible for regulating the expression of target genes.To comprehend the characteristics and mutations of the PPARGC1B gene within the Sichuan yak population,the SNP loci of the PPARGC1B gene were identified through direct sequencing of PCR products.Additionally,the cod-ing region of the PPARGC1B gene was obtained via PCR amplification and sequencing.Bioinforma-tics analyses were conducted to predict protein-coding and mRNA secondary structure.This study identified four exon SNP mutation sites(E9-189A→C,E9-387G→A,E9-542C→T,and E9-554T→C)based on the single nucleotide polymorphism analysis of the PPARGC1B gene in Sichuan yaks.Notably,the E9-387G→A and E9-554T→C loci exhibited significant correlations with shear force and backfat thickness in Sichuan yaks.Subsequently,bioinformatics analysis of the four mutation sites revealed that the PPARGC1B protein is an acidic,unstable,non-transmembrane,and non-secretory hydrophilic protein with a coiled helix structure.It lacks a signal peptide and transmembrane region,predominantly functions in the nucleus,and features 106 phosphorylation sites,one glycosylation site,and one conserved RRM structure.The secondary structure comprises mainly α-helix and random coils.Although the protein structure of the PPARGC1B gene remained unchanged post-mutation,there were significant differences in mRNA secondary structure.These findings suggest that the polymorphic loci of the PPARGC1B gene in Sichuan yaks could serve as a theoretical basis for enhancing meat quality traits through molecular biological methods,presen-ting practical applications in breeding.

Objective:To explore the pathogenesis of neuropsychiatric systemic lupus erythematosus (NPSLE) from imaging perspective by analyzing voxel-based morphology (VBM) and functional connectivity (FC) in resting state functional magnetic resonance imaging (rs-fMRI).Methods:Thirty-five patients with NPSLE and 30 patients with non-NPSLE admitted to Department of Rheumatology and Immunology, Taizhou People's Hospital Affiliated to Nanjing Medical University from June 2020 to March 2023 were enrolled; 31 healthy subjects were included as healthy control group during the same period. All subjects completed routine MRI and rs-fMRI, laboratory tests (C3, C4, IgA, IgM and IgG levels), mini-mental state examination (MMSE), hospital anxiety and depression scale (HADS), and fatigue scale for motor and cognitive functions (FSMC). Whole brain gray matter volume in subjects of the 3 groups was analyzed by VBM method, and the brain regions enjoying significant differences in gray matter volume between the NPSLE group and non-NPSLE group were selected as regions of interest (ROIs) for whole brain FC analysis. Partial correlation method was used to analyze the correlations of imaging indexes in brain regions enjoying significant differences with clinical indexes and imaging scores between NPSLE group and non-NPSLE group. Efficacy of imaging indexes in brain regions enjoying significant difference in differentiating NPSLE from non-NPSLE was analyzed by receiver operating characteristic (ROC) curve.Results:(1) Covariance analysis among the 3 groups showed that the gray matter volume in the left inferior frontal gyrus of orbit, left superior frontal gyrus, right rectus gyrus, right transverse temporal gyrus, and right superior frontal gyrus was significantly different among the 3 groups ( P<0.001, FDR corrected); compared with the healthy control group, the NPSLE group had significantly reduced gray matter volume in the left inferior frontal gyrus of orbit, left superior frontal gyrus of orbit, right rectus gyrus, right transverse temporal gyrus, and right superior frontal gyrus ( P<0.001, FDR corrected); compared with the non-NPSLE group, the NPSLE group had significantly decreased gray matter volume in the left inferior frontal gyrus of orbit, right rectus gyrus, and right transverse temporal gyrus ( P<0.001, FDR corrected). (2) Whole brain FC analysis with brain regions enjoying significant differences as seed points showed that Fisher z-transformed FC (zFC) in the right transverse temporal gyrus and bilateral postcentral gyrus of the NPSLE group were significantly decreased ( P<0.001, FDR corrected). (3) Partial correlation analysis showed that, in the NPSLE group, zFC from the right transverse temporal gyrus to left posterior central gyrus was negatively correlated with disease course ( r=-0.390, P=0.027); gray matter volume in the right orbital superior frontal gyrus was negatively correlated with FSMC-cognitive ( r=-0.401, P=0.023); the gray matter volume in the right orbital superior frontal gyrus was negatively correlated with FSMC-motor ( r=-0.374, P=0.035). (4) ROC curve found that gray matter volume in the right rectus gyrus and zFC from the right transverse temporal gyrus to the right posterior central gyrus had relatively high efficacy in differentiating NPSLE from non-NPSLE, with AUC of 0.771 (95% CI: 0.658-0.885, P<0.001) and 0.794 (95% CI: 0.685-0.904, P<0.001), respectively. Conclusion:NPSLE patients have reduced gray matter volume in multiple brain regions (concentrating in the prefrontal limbic system); and reduced FC with some brain regions is noted; multiple indexes are correlated with clinical indexes.

ObjectiveTo develop a new mosquito trap and evaluate its effectiveness in Aedes albopictus monitoring in an urban community. MethodsThe first-round field test was conducted in a well-greened residential neighborhood with high Aedes albopictus density calculated by human landing catch in August 2022, in Minhang District, Shanghai. 65 new test containers with different designs were randomly deployed in the field. These trap containers were designed by different material, color, hole size, shape and top cover colors. The results of mosquito and its egg trapping were observed and recorded continuously for 7 days. In September 2022, the second round of experiment was conducted. After comparison, an optimized trap container was designed. 140 new trap containers were compared with 140 traditional ones to evaluate the effectiveness. SPSS 22.5 software was used for statistical analysis. ResultsThere were significant changes in the outcome of mosquito and its egg trapping on the 4th and 7th day of the pre-experiment deployment of the three kinds of containers. The 200 ml container cup with three round holes in the body had the best effect on trapping mosquitos and eggs, with a positive rate of 45.5% (5/11), while other type of contrainer cup only had a positive rate of 12% (6/50) in trapping mosquitos and eggs. Statistical significant differences (χ2=45.443,P <0.001) existed between the two tpyes of cups within the first kind of trapping container. The second kind of trapping container showed round and oval holes had better effect on mosquito trapping, with a positive rate of 55.6% (5/9). The third kind of hanging container can resist strong wind. The best mosquito trapping effect of three round holes was 66.7% (2/3). The container wall should not be made of rough material, which was easy to cause the escape of adult mosquitoes. Combined with the three types of containers, the new contariner should be top transparent, and the top 1/3 of the side should paint black with 3 round holes. The effective recovery rate of the new container was higher than that of the traditional one under the exclusion of human factors, and had the advantage of preventing rain, wind and rollover, but the effect of trapping mosquito and its egg was comparable to the traditional one(χ2D4=0.197,P=0.658; χ2D7=0.125 ,P=0.724). ConclusionThis new type of mosquito trap is worth further exploration and research, which can improve the trapping efficiency, overall recovery rate and the accurate confirmation of the mosquito density.

INTRODUCTION:
To date, there have only been 2 systematic reviews, and 1 systematic review and meta-analysis on high-intensity focused ultrasound (HIFU) for benign thyroid nodules. The present systematic review and meta-analysis seeks to evaluate the efficacy and safety of HIFU in the treatment of benign thyroid nodules.
METHODS:
Pubmed, Embase and Cochrane databases were searched for relevant studies from 1990 to 2021. Nine studies were included in the systematic review and 6 in the meta-analysis. Pooled volume reduction rates (VRRs) at 3, 6 and 24 months after HIFU were assessed.
RESULTS:
This systematic review and meta-analysis showed that pooled VRRs at 3, 6, and 24 months after HIFU were 42.14 (95% confidence interval [CI] 28.66-55.62, I2=91%), 53.51 (95% CI 36.78-70.25, I2=97%) and 46.89 (95% CI 18.87-74.92, I2=99%), respectively. There was significant heterogeneity in the pooled VRRs at 3, 6 and 24 months after HIFU. No studies recorded complete disappearance of the nodules. Common side effects included pain, skin changes and oedema. There were no major complications except for transient vocal cord paralysis and voice hoarseness (0.014%) and transient Horner syndrome (0.5%).
CONCLUSION
HIFU may be an effective and safe alternative treatment modality for benign thyroid nodules. Larger clinical trials with longer follow-up are needed to evaluate the effectiveness of HIFU in treating benign thyroid nodules.
