Objective To evaluate the necessity and safety of implanting temporary vena eava fihers to prevent pulmonary emboli in patients of lower extremity fractures concomitant with acute deep venous thrombosis(DVT). Methods A total of 782 patients with lower extremity fractures were complicated with DVT perioperatively. Among them, 91 received temporary vena cava filters implantation before orthopedic operations for the prevention of pulmonary embolism. All patients were followed up post-operation. Results Vena cava filters were successfully implanted in 89 patients. Mean implantation time was 27 days (range from 14 to 42 days). Thrombus trapped within the filters were found in 78 patients (87.6%) after the filters removal. Eight-two filters (92.1%) were retrived successfully at the first attempt as scheduled. Seven filters(7.9%) with big trapped thrombi were removed at the 2nd attempt after additional thrombolytic therapy. No patients needed a permanent filter. No fetal pulmonary embolism (PE) or other major complications were detected during the three to six months follow-ups period. Conclusion Temporary vena cava filter can reduce the incidence and mortality of pulmonary embolism as well as the occurrence of mid- or long-term complications in lower limb fracture patients complicated with DVT.

[Objective]To evaluate the terminal hair growth of different body positions among in pregnant women ,analyze the contribution of each area to the diagnosis to hirsutism ,to improve the mFG scoring system.[Method]Pregnant women aged 20~41 years,with normal range of total testosterone levels and non-hirsute were recruited at their prenatal care in Sun Yat-sen Memorial Hospital,Sun Yat-sen University. They were followed up before pregnancy,at the 5th and the 9th week,the 10th and the 14th week, the 15th and the 20th week,the 21th and the 24th week of gestation. Then 72 more cases of pregnant women were recruited and followed up at 15~24th week. At each time of followed up,their total testosterone(TT)levels was examined by liquid chromatography tandem mass spectrometry(LC/MS-MS)and terminal hair growth were assessed by mFG score. Significant difference procedure least(LSD) analysis of variance was used to compare the levels of testosterone and mFG score in different gestational weeks. Receiver operating characteristics(ROC)analysis and logistics analysis were conducted to evaluate the contributory strength of hair growth in each body position for the diagnosis of hirsutism. The scores in the body area which made a significant contribution to the total were summed up and termed the simplified mFG score(sFG score). Following,the sFG scores were subjected to ROC analysis to determine the thresh-old that would maximize both the sensitivity and specificity of the measure to accurately distinguish hirsute from non-hirsute patients.[Results]Among the forty three pregnant women who were followed-up from before pregnancy to 24th week,the mean±SD for TT was (1.09 ± 0.59)nmol/L before pregnancy,and(1.13 ± 0.40),(1.28 ± 0.38),(1.83 ± 0.63),(1.82 ± 0.52)nmol/L for 5~ 9th,10~14th,15~20th week,and the mFG score was 1.65 ± 0.60,2.30 ± 0.45,3.60 ± 0.68,4.20 ± 0.41 and 4.40 ± 0.77,respectively. The order of the facial and body sites presented with new terminal hair growth was upper abdomen,lower abdomen,lower back,up-per lip,thighs,upper back,chest,upper arm,and chin,in sequence. After analyzing 115 cases(including the 72 cases recruited later),ROC analysis showed that the diagnostic value of different sites for hirsutism(mFG≥5):upper lip>lower back>thighs>lower abdomen>upper arm>upper back>chest/upper abdomen. Four sites among them ,namely upper lip ,lower back ,thighs and lower abdomen had the best diagnostic value,and the AUC for ROC were 0.779,0.728,0.675,and 0.626,respectively. Both ROC and logistic analysis indicated that he most significant body areas in defining hirsutism(defined as an mFG score≥5)were the upper lip, lower back,thighs,and lower abdomen. Using a cut-off value of 3,the combination of the four areas has the best sensitivity and specificity in distinguishing hirsute from non-hirsute women. [Conclusion]The study suggested that the mFG score increased as pregnancy progressed before the 24 weeks of gestation. The subset of upper lip,lower back,thighs and lower abdomen may be a reli-able simplification of mFG system for the evaluation of excess hair growth. The cut-off value was of≥3.

Objective:To investigate the effect of behavioral lifestyle on the CT values of urinary tract stones, as well as the relationship between behavioral lifestyle and the therapeutic effect of extracorporeal shock wave lithotripsy (ESWL).Methods:A total of 265 patients with urinary tract stones who underwent ESWL treatment at Affiliated Hospital of Jining Medical University from January 2019 to June 2023 were selected. According to the CT values of the stones, the subjects were divided into high CT value group (CT value > 1 000 HU, n=106) and low CT value group (CT value ≤ 1 000 HU, n=159). A retrospective survey was conducted to assess the patients' behavioral lifestyles, and general data, CT values, number of lithotripsy sessions, lithotripsy time, lithotripsy efficiency, and incidence of complications were compared between the two groups. SPSS 22.0 software was used for statistical analysis. The χ2 test and t-test were used for group comparisons, and Pearson correlation analysis was used to examine the relationship between stone CT values and different behavioral lifestyles. Results:The high CT value group had lower average daily water intake((1 242±347)mL vs (1 784±376)mL), average daily fresh fruit intake((135±43)g vs (196±51)g), and average daily exercise time((18±12)min vs (32±14)min) compared with the low CT value group( t=-11.850, -9.926, -8.434, all P<0.01). In contrast, the high CT value group had higher average daily salt intake((8.3±2.2)g vs (6.5±1.7)g) and average daily animal protein intake ((72±18)g vs (54±16)g) compared with the low CT value group ( t=7.495, 8.531, both P<0.01). The high CT value group required more lithotripsy sessions and longer lithotripsy time than the low CT value group ( t=6.192, 7.507, both P<0.05), while lithotripsy efficiency was lower than the low CT value group ( χ2=33.181, P<0.01). The incidence of complications was higher in the high CT value group compared to the low CT value group ( χ2=3.915, P=0.048), with statistically significant differences. Conclusion:Appropriate water intake, diet, and exercise habits are beneficial in reducing stone CT values, improving the efficacy of ESWL treatment, and decreasing the incidence of complications.

This study aimed to explore the mechanism of how African swine fever virus (ASFV) I226R protein inhibits the cGAS-STING signaling pathway. We observed that I226R protein (pI226R) significantly inhibited the cGAS-STING-mediated type Ⅰ interferons and the interferon-stimulated genes production by dual-luciferase reporter assay system and real-time quantitative PCR. The results of co-immunoprecipitation assay and confocal microscopy showed that pI226R interacted with cGAS. Furthermore, pI226R promoted cGAS degradation through autophagy-lysosome pathway. Moreover, we found that pI226R decreased the binding of cGAS to E3 ligase tripartite motif protein 56 (TRIM56), resulting in the weakened monoubiquitination of cGAS, thus inhibiting the activation of cGAS and cGAS-STING signaling. In conclusion, ASFV pI226R suppresses the antiviral innate immune response by antagonizing cGAS, which contributes to an in-depth understanding of the immune escape mechanism of ASFV and provides a theoretical basis for the development of vaccines.

In order to understand the prevalence and evolution of porcine reproductive and respiratory syndrome virus (PRRSV) in China and to develop subunit vaccine against the epidemic lineage, the genetic evolution analysis of PRRSV strains isolated in China from 2001 to 2021 was performed. The representative strains of the dominant epidemic lineage were selected to optimize the membrane protein GP5 and M nucleotide sequences, which were used, with the interferon and the Fc region of immunoglobulin, to construct the eukaryotic expression plasmids pCDNA3.4-IFNα-GP5-Fc and pCDNA3.4-IFNα-M-Fc. Subsequently, the recombinant proteins IFNα-GP5-Fc and IFNα-M-Fc were expressed by HEK293T eukaryotic expression system. The two recombinant proteins were mixed with ISA206VG adjuvant to immunize weaned piglets. The humoral immunity level was evaluated by ELISA and neutralization test, and the cellular immunity level was detected by ELISPOT test. The results showed that the NADC30-like lineage was the main epidemic lineage in China in recent years, and the combination of IFNα-GP5-Fc and IFNα-M-Fc could induce high levels of antibody and cellular immunity in piglets. This study may facilitate the preparation of a safer and more effective new PRRSV subunit vaccine.
