Objective To explore the behavioral characteristics of using cognitive reappraisal(CR)and expressive suppression(ES)in high trait anxiety individuals under both explicit and implicit conditions.Methods A total of 57 non-psychology undergraduates and postgraduates were recruited in a military medical university from June to July in 2023.All the participants were surveyed with Trait Form of Spielberger's State-Trait Anxiety Inventory(STAI-T)and Emotion Regulation Questionnaire(ERQ)to investigate their level of anxiety and usage habits of CR and ES strategies.According to the STAI-T results,they were divided to a high trait anxiety(HTA)group(n=28)and a low trait anxiety(LTA)group(n=29).Then the implicit and explicit emotion regulation(ER)tasks were used to analyze and compare 2 strategies on improving negative emotional pleasure and arousal,and the differences in difficulty and success of using CR and ES under the explicit condition.Results ① Both the HTA and LTA individuals showed a higher use of CR and less use of ES[t(27)=3.94,P<0.001;t(28)=11.33,P<0.001],while the HTA individuals used more ES[t(55)=3.02,P<0.01]and less CR than the LTA individuals[t(55)=-2.20,P=0.02].②Compared with implicit neutral priming,both implicit CR(Pleasure:2.56±0.11 vs 2.73±0.12,P<0.01;Arousal:6.68±0.18 vs 6.51±0.20,P<0.05)and implicit ES priming(Pleasure:2.56±0.11 vs 2.86±0.11,P<0.001;Arousal:6.68±0.18 vs 6.30±0.20,P<0.001)improved the negative emotional experiences of both HTA and LTA groups,and ES showed better effect(Pleasure:P<0.001;Arousal:P<0.001).③ Explicit CR(Pleasure:2.92±0.12 vs 5.09±0.09,P<0.001;Arousal:6.43±0.20 vs 4.33±0.21,P<0.001)and explicit ES(Pleasure:2.92±0.12 vs 4.34±0.09,P<0.001;Arousal:6.43±0.20 vs 4.22±0.22,P<0.001)ameliorated the negative feelings in the HTA and LTA individuals,and the effect of explicit CR on improving pleasure was superior than that of explicit ES(P<0.001).For the HTA individuals,it is more difficult to implement CR and ES[CR:t(55)=2.16,P=0.02;ES:t(55)=2.92,P<0.01],and ES was less successful in emotion regulation when compared with the LTA individuals[t(55)=-1.88,P=0.03];the difficulty of using ES was significantly higher than that of CR[4.00±1.81 vs 5.00±1.80,t(27)=-2.78,P<0.01],and the success rate was also lower[7.04±1.00 vs 6.64±1.13,t(27)=2.09,P=0.02].④ Comparing the effects of emotion regulation under implicit and explicit conditions,it was presented that explicit CR and ES were better than implicit CR and ES for both HTA and LTA individuals(Pleasure:explicit CR vs implicit CR:5.09±0.09 vs 2.73±0.12,P<0.001;explicit ES vs implicit ES:4.34±0.09 vs 2.86±0.11,P<0.001;Arousal:explicit CR vs implicit CR:4.33±0.21 vs 6.51±0.20,P<0.001;explicit ES vs implicit ES:4.22±0.22 vs 6.30±0.20,P<0.001).Conclusion In terms of usage habits of ER strategies,HTA individuals tend to use ES more and CR less than LTA individuals.Under the implicit/explicit conditions,HTA individuals can both employ CR and ES to improve negative emotional experience,and the effect of explicit ER is significantly better than implicit condition.

Objective:To evaluate the clinical efficacy of cannulated screws combined with suture anchor in the treatment of comminuted patellar fractures.Methods:A retrospective study was conducted to analyze the data of 72 patients who had been admitted to Department of Orthopaedics, The Second Hospital of Shanxi Medical University for comminuted patellar fractures between January 2020 and June 2023. The patients were divided into 2 groups based on the surgical techniques used. In group A of 34 patients subjected to fixation using cannulated screws combined with suture anchors, there were 22 males and 12 females with an age of 49 (39, 58) years, and 7 cases of AO type 34-C2 and 27 cases of AO type 34-C3. In group B of 38 patients subjected to fixation using cannulated screws combined with titanium cables, there were 19 males and 19 females with an age of 55 (40, 62) years, and 11 cases of AO type 34-C2 and 27 cases of AO type 34-C3. Comparisons were made between the 2 groups regarding general preoperative data, postoperative range of knee motion, fracture healing time, complications, soft tissue irritation, secondary surgery, postoperative pain assessed by visual analogue scale (VAS), postoperative Bostman knee score, and postoperative Levack knee score.Results:The 2 groups were comparable because there were no statistically significant differences in the general preoperative data and follow-up time between them ( P>0.05). There were no statistically significant differences between the 2 groups either in postoperative range of knee motion, fracture healing time, or Bostman knee score or Levack knee score at the last follow-up (all P>0.05). In group A, the VAS pain score and the rate of soft tissue irritation at the last follow-up were respectively 0.0 (0.0, 1.0) and 0% (0/34), significantly lower than those in group B [1.0 (0.0, 1.3) and 15.8% (6/38)] ( P<0.05). The overall incidence of complications and secondary surgery rate in group A were respectively 5.9% (2/34) and 2.9% (1/34), lower than those in group B [21.1% (8/38) and 15.8% (6/38)], but showing no statistically significant difference between the 2 groups ( P>0.05). Conclusions:In the treatment of comminuted patellar fractures, fixation using cannulated screws combined with both titanium cables and suture anchors can lead to comparable clinical efficacy, but fixation using cannulated screws and suture anchors can reduce soft tissue irritation, alleviate pain, and improve the quality of life of patients.

Objective:
To screen the differential genes and pathways of female and male C57 BL/6 J mice by transcriptome sequencing, and to lay a foundation for further exploring the molecular mechanism of behavioral differences between male and female mice.
Methods:
8-week-old female and male mice of the C57 BL/6 J strain were completely isolated from the mouse hippocampus, and total RNA was extracted and reverse transcribed to construct a cDNA library, and 50 single-ended mice were generated on the BGIseq500 platform(BGl-Shenzhen, China) The base reads were transcriptome sequenced. After sequencing, based on GO and KEGG databases, combined with the phyper function in R language to screen, correct and enrich the data, calculatePvalue, and then perform FDR correction onPvalue to obtainQvalue and analyze different annotated genes based on the hypergeometric test method. The expression status was analyzed, and the differential genes and pathways in the hippocampus of mice of different genders were screened out.
Results:
Through the comparison of male and female differences, 325 differential genes were screened, including 233 up-regulated genes and 92 down-regulated genes. The functions of these differential genes were mainly enriched in long-term potentiation(LTP), calcium signal pathway, nicotine addiction and other processes. There were 362 junctions and 1 703 interaction edges in the female-male differential gene interaction network, and 10 core genes selected: lysine demethylase 5 D(Kdm5 d), cyclin-dependent kinase 5(Cdkl5), Cell output mediator(Cle1), dopamine receptor 6 a3(Slc6 a3), cassette transcription factor(Fox), precursor mRNA processing factor 4 B(Prpf4 b), glycine receptor 4(Glur4), calcium ion receptor 2(Camk2), DNA and RNA binding protein family(Son), serotonin receptor 5 b(Htr5 b).
Conclusion
The selected differential genes and signal pathways may lay the foundation for explaining the molecular mechanism of the differences in behavior between male and female mice.

Objective To analyse the imaging characteristics of solitary pulmonary nodules(SPNs) with the spiral CT, and detection clinical values of the definitive diagnosis to SPNs. Methods 32 cases of SPNs were identified by spiral CT, 9 cases of them were examinated by enhancement scanning. The diffrentical imaging features were analyzed. Results 24 cases were malignant in imaging(18 cases were identified), 8 cases were benign in imaging(6 cases were identified). 15 cases of malignant SPNs by clinical identified were smooth at edge; 6 cases of benign SPNs by clinical identified. 5 cases of them were anomaly;4 cases of them were burr;2 cases of them were bronchial sign and vesiclat sign.6 cases of the SPNs were calcified. 6 cases of SPNs(9 cases with contrasting) were benign in imaging, 3 cases of them were malignant in imaging. Conclusion The differential diagnostic of SPNs is difficult by spiral CT, but enhancement scanning and epidemiology combined with spiral CT is very valuable for definitive diagnosis.
