Objective To study the effect of IGF-1 gene therapy and electric stimulation therapy on the rat models of postpartum stress urinary incontinence, and explore the ideal treatment for this disease.Methods 240 SD female rats were used to establish the model of postpartum stress urinary incontinence by water sac vaginal dilation.148 model rats were randomly selected from 185 successful models and divided into 5 groups:IGF-1 gene therapy, clenbuterol treatment, electric stimulation therapy, injection of empty vector plasmid, and untreated groups.Besides, 20 non-modeled rats were used as blank control group.Urodynamic test was performed, pelvic floor pubococcygeus muscle/muscle weight ratio was calculated, and serum biochemical indices (LDH, CK) were detected, and the morphological changes of pubococcygeus muscle fibers were observed by light microscopy at 1, 21, 42 and 63 days after treatment.Results At 21 days after treat-ment, the maximum bladder capacity, leak point pressure, the contractile force/muscle weight ratio in the IGF-1 group and electric stimulation treatment group were significantly better (P>0.05), and the differences between the IGF-1 group and electric stimulation group were not significant ( P>0.05 ) .Conclusions The effect of IGF-1 gene therapy and electric stimulation on the rat models of postpartum stress urinary incontinence is better than that in the drug therapy group and oth-er groups.

Objective To investigate the expression of sialic acid-binding immunoglobulin-like lectin-1 (Siglec-1) in the peripheral blood mononuclear cells (PBMCs) in patients with rheumatoid arthritis (RA),osteoarthritis (OA) and healthy controls and to explore the relationship between Siglec-1 expression and disease activity in RA.Methods Siglec-1 protein and mRNA levels were measured by flow cytometry and real-time quantitative reversetranscription-polymerase chain reaction (qRT-PCR) in 42 RA patients,28 OA patients and 26 healthy controls,respectively.The correlation studies between Siglec-1 and disease activity score 28 (DAS28) or C-reactive protein were performed.T-test was used for comparisons between groups and Pearson's correlation test was used for correlation analysis.Results The percentage of Siglec-1 positive cells of PBMCs in RA group [(15.2±7.6)％] was significantly higher than that in the OA group [(2.3 ±2.6)％] or healthy controls [(2.1±1.6)％,t=8.615,8.661; all P＜0.01].And the major cell type in PBMCs that expressed Siglec-1 was monocytes.The relative Siglec-1 mRNA expression in PBMCs in the RA group (3.4±1.5) was also significantly higher than that in the OA group (1.2±0.4) or healthy controls [(1.0± 0.4),t=3.446,3.966; all P＜0.05].But no significant differences of Siglec-1 protein and mRNA between the OA group and healthy controls were found.Furthermore,positive correlations between Siglec-1 protein and DAS28 or hs-CRP were found in RA patients (r=0.89,P＜0.01; r=0.48,P＜0.01).Conclusion PBMCs are activated which are characterized by elevated expression of Siglec-1 in RA patients.Circulating Siglec-1 may be considered as a potential noninvasive biomarker for monitoring disease activity in RA.

Objective:To explore the morphological characteristics of the pectoralis major muscle and the anatomical relationship of adjacent structures .Methods:A total of 156 patients undergoing thyroid surgery at the First Hospital of Anhui University of Science & Technology and the First Affiliated Hospital of University of Science and Technology of China from Dec 2020 to Sep 2022 were includeed. Those adopting routine endoscopic thyroidectomy by gasless unilateral axillary approach were assigned to group A,and searching for the sternocleidomastoid muscle through the pectoralis major muscle gap on this basis to group B.Results:Among the 78 patients in group B, a total of 71 (91%) cases were found to have a typical sternocleidomastoid muscle gap, and in 7 (9%) cases were not found. The morphology phenotypes of the gap between the clavicular part and thoracic ribs part of the pectoralis major muscle was found in 3 types: obvious separation type (typeⅠ), inconspicuous separation-partially overlapped type (typeⅡa), and inconspicuous separation-completely anastomosed type (type Ⅱb). The mean duration of surgery in group B was less (105±15) min than that in group A (156±27) min ( t=14.523, P<0.01); postoperative one day drainage in group B was less (49±6) ml than that in group A (51±6) ml ( t=2.273, P=0.024). There was no statistically significant difference in intraoperative bleeding, postoperative hospital stay and complication rate between the two groups ( t=0.557, P=0.578; t=0.134, P=0.894; χ2=1.844, P=0.174). Conclusion:The search for the sternocleidomastoid muscle through the pectoralis major muscle gap in the endoscopic thyroidectomy by gasless unilateral axillary approach can shorten the duration of surgery and improve the efficiency of surgery.

Background: () (2n = 2x = 16) is genus of flowering plants belonging to the Gelsemicaeae family. Method: Here, a high-quality genome assembly using the Oxford Nanopore Technologies (ONT) platform and high-throughput chromosome conformation capture techniques (Hi-C) were used. Results: A total of 56.11 Gb of raw GridION X5 platform ONT reads (6.23 Gb per cell) were generated. After filtering, 53.45 Gb of clean reads were obtained, giving 160 × coverage depth. The genome assemblies 335.13 Mb, close to the 338 Mb estimated by k-mer analysis, was generated with contig N50 of 10.23 Mb. The vast majority (99.2%) of the assembled sequence was anchored onto 8 pseudo-chromosomes. The genome completeness was then evaluated and 1338 of the 1440 conserved genes (92.9%) could be found in the assembly. Genome annotation revealed that 43.16% of the genome is composed of repetitive elements and 23.9% is composed of long terminal repeat elements. We predicted 26,768 protein-coding genes, of which 84.56% were functionally annotated. Conclusion The genomic sequences of could be a valuable source for comparative genomic analysis in the Gelsemicaeae family and will be useful for understanding the phylogenetic relationships of the indole alkaloid metabolism.

Objective    To explore the predictive value of a simple prediction model for patients with acute myocardial infarction. Methods    Clinical data of 280 patients with acute ST-segment elevation myocardial infarction (STEMI) in the Department of Emergence Medicine, West China Hospital of Sichuan University from January 2019 to January 2020 were retrospectively analyzed. The patients were divided into a death group (n=34) and a survival group (n=246). Results    Age, heart rate, body mass index (BMI), global registry of acute coronary events (GRACE), thrombolysis in myocardial infarction trial (TIMI) score, blood urea nitrogen, serum cystatin C and D-dimer in the survival group were less or lower than those in the death group (P<0.05). Left ventricle ejection fraction and the level of albumin, triglyceride, total cholesterol and low density lipoprotein cholesterol were higher and the incidence of Killip class≥Ⅲ was lower in the survival group compared to the death group (P<0.05). Multivariate logistic regression analysis showed that age, BMI, heart rate, diastolic blood pressure, and systolic blood pressure were independent risk factors for all-cause death in STEMI patients. Receiver operating characteristic (ROC) curve analysis showed that the area under the curve of simple prediction model for predicting death was 0.802, and similar to that of GRACE (0.816). The H-L test showed that the simple model had high accuracy in predicting death (χ2=3.77, P=0.877). Pearson correlation analysis showed that the simple prediction model was significantly correlated with the GRACE (r=0.651, P<0.001) and coronary artery stenosis score (r=0.210, P=0.001). Conclusion    The simple prediction model may be used to predict the hospitalization and long-term outcomes of STEMI patients, which is helpful to stratify high risk patients and to guide treatment.

Objective    To analyze prognostic ability of inflammation-based Glasgow prognostic score (GPS) in patients with ST-segment elevation myocardial infarction (STEMI). Methods    We retrospectively analyzed the clinical data of 289 patients with STEMI admitted to the Department of Emergency in West China Hospital from April 2015 to January 2016. All study subjects were divided into three groups: a group of GPS 0 (190 patients including 150 males and 40 females aged 62.63±12.98 years), a group of GPS 1 (78 patients including 58 males and 20 females aged 66.57±15.25 years), and a group of GPS 2 (21 patients including 16 males and 5 females aged 70.95±9.58 years). Cox regression analysis was conducted to analyze the independent risk factors of predicting long-term mortality of patients with STEMI. Results    There was a statistical difference in long-term mortality (9.5% vs. 23.1% vs. 61.9%, P<0.001) and in-hospital mortality (3.7% vs. 7.7% vs. 23.8%, P<0.001) among the three groups. The Global Registry of Acute Coronary Events (GRACE) scores and Gensini scores increased in patients with higher GPS scores, and the differences were statistically different (P<0.001). Multivariable Cox regression analysis showed that the GPS was independently associated with STEMI long-term all-cause mortality (1 vs. 0, HR: 2.212, P=0.037; 2 vs. 0, HR: 8.286, P<0.001). Conclusion    GPS score is helpful in predicting the long-term and in-hospital prognosis of STEMI patients, and thus may guide clinical precise intervention by early risk stratification.
