Objective To investigate the correlation of vascular senescence indicators,brachial-ankle pulse wave velocity(baPWV),cardio-ankle vascular index(CAVI),ankle-brachial index(ABI)with total burden of MRI in patients with cerebral small vessel disease(CSVD).Methods A total of 200 CSVD patients admitted to our hospital from November 2023 to October 2024 were retrospectively recruited,and based on their total MRI burden,they were divided into a low-burden group(score:0-1,103 cases)and a high-burden group(score:2-4,97 cases).A athero-sclerosis monitoring device(VS-1500A)was used to detect baPWV,CAVI,and ABI values.The relationships of the three indicators with total MRI burden score and their predictive values for the burden score were analyzed.Results The high-burden group had significantly higher BMI,el-evated homocysteine and uric acid levels,and increased baPWV and CAVI,but lower ABI than the low-burden group(P＜0.01).Multivariate logistic analysis showed that baPWV,CAVI and ABI were independent influencing factors for high MRI burden of CSVD patients.Spearman correlation analysis showed that baPWV and CAVI values were positively correlated(r=0.589,P=0.000;r=0.458,P=0.000),and ABI was negatively correlated with the total MRI burden score of CSVD patients(r=-0.352,P=0.000).ROC curve analysis showed that baPWV(AUC=0.816,P=0.000),CAVI(AUC=0.725,P=0.000)and ABI(AUC=0.676,P=0.000)were all predic-tors for high MRI burden score in CSVD patients.Conclusion baPWV and CAVI are positively,and ABI is negatively correlated with the total MRI burden score of CSVD patients.baPWV,CAVI and ABI show higher predictive value for the high burden score,with baPWV most significant.

BACKGROUND:Our previous research found that Tougu Xiaotong Capsules can be used not only for the treatment of osteoarthritis,but also for rheumatoid arthritis and gouty arthritis.However,the specific mechanism of action of"Same Treatment for Different Diseases"is still unclear.OBJECTIVE:To identify the main effects and mechanisms of Tougu Xiaotong Capsules in the treatment of osteoarthritis,rheumatoid arthritis and gouty arthritis with the treating principle of"Same Treatment for Different Diseases"by the methodologies of integrated pharmacology,molecular docking techniques and molecular dynamics simulation.METHODS:The active chemical components of Tougu Xiaotong Capsules and their corresponding targets were retrieved from the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform(TCMSP)and the Swiss Target Prediction database.The disease genes for osteoarthritis,rheumatoid arthritis and gouty arthritis were obtained from the GeneCards and OMIM databases.Cytoscape 3.7.2 software was used to construct a drug-component-disease-target network diagram and a protein-protein interaction network.Gene ontology analysis and Kyoto Encyclopedia of Genes and Genomes enrichment analysis were conducted using the Daivd database.Molecular docking simulations were performed on the CB-DOCK2 website,and molecular dynamics simulations were carried out using the GROMACS 2020.6 software.RESULTS AND CONCLUSION:(1)A total of 50 active components of Tougu Xiaotong Capsules were screened,with 184 potential targets and 29 intersection targets across the three types of arthritis.(2)The gene ontology enrichment analysis of the intersection targets indicated that the key gene functions of Tougu Xiaotong Capsules in treating the three types of arthritis were found to be cellular response to lipopolysaccharide,inflammatory response,extracellular matrix,protein binding,and zinc ion binding.(3)Kyoto Encyclopedia of Genes and Genomes enrichment analysis identified key pathways as interleukin-17 signaling pathway,tumor necrosis factor signaling pathway,NOD-like receptor and Toll-like receptor signaling pathways.(4)Six core targets[interleukin-6,interleukin-1β,prostaglandin endoperoxide synthase 1,prostaglandin endoperoxide synthase 2,cytochrome P450 1A2(CYP1A2)and C-X-C chemokine ligand 8]were determined based on the protein-protein interaction network.(5)Molecular docking results confirmed that(+)-catechin,β-sitosterol,kaempferol,myricetin,and wallichilide had good structure-activity relationships.Molecular dynamics simulations further confirmed the stable binding of CYP1A2 with wallichilide,corroborating the network pharmacology and molecular docking results.Therefore,Tougu Xiaotong Capsules may regulate the interleukin-17 signaling pathway,tumor necrosis factor signaling pathway,and other signaling pathways by targeting interleukin-1β,prostaglandin endoperoxide synthase 1,prostaglandin endoperoxide synthase 2 and CYP1A2,exert an effect of"Same Treatment for Different Diseases"on osteoarthritis,rheumatoid arthritis and gouty arthritis.

Objective To understand the epidemiological characteristics and trends of postoperative pneumonia(POP)in tertiary general hospitals in Jiangsu Province,and provide theoretical basis for carrying out targeted pre-vention and control measures.Methods Surgery patients from 22 tertiary general hospitals in 12 cities in north,central,and south of Jiangsu Province from January 1,2022 to December 31,2023 were chosen as studied subjects,occurrence of POP was analyzed and compared.Results A total of 848 274 surgical procedures were performed in 22 hospitals,and 3 606 cases of POP occurred,with an incidence of 0.43％.The incidence in 2023 was 0.37％,which was lower than that in 2022(0.49％),with statistically significant difference(P＜0.001).The top three de-partments with high incidence of POP were neurosurgery(6.71％),cardiothoracic surgery(2.91％),and general surgery(0.77％).Among hospitals of different grades,the incidence of POP in tertiary first-class hospitals was 0.44％,which was higher than that in other tertiary hospitals(0.37％).There was no statistically significant difference in the incidence of POP between municipal and district/county hospitals(P＞0.05).The incidence of POP in hospitals with a bed:infection control full-time staff ratio＜200∶1 was lower than that in hospitals with the ratio ≥200∶1(0.39％vs 0.47％,P＜0.001),while the incidence of POP in hospitals with a proportion ≥30％of full-time staff being doctors was higher than that in hospitals with a proportion＜30％(0.45％vs 0.36％,P＜0.001).The incidence of POP in male patients was higher than that in female patients(0.62％vs 0.26％,P＜0.001).The incidence of POP in elderly patients aged≥65 was higher than that in patients aged＜65(0.73％vs 0.26％,P＜0.001).A total of 2 667 strains of infectious pathogens were detected,with the top three being Acine-tobacter baumannii,Klebsiella pneumoniae,and Pseudomonas aeruginosa,accounting for 28.95％,22.72％,and 15.45％,respectively.The detection rates of carbapenem-resistant Acinetobacter baumannii(CRAB),carba-penem-resistant Klebsiella pneumoniae(CRKP),and carbapenem-resistant Pseudomonas aeruginosa(CRPA)were 60.75％,21.45％,and 32.28％,respectively.The detection rate of CRKP decreased in 2023 compared with 2022,with statistically significant difference(P＜0.05).Conclusion The overall incidence of POP in tertiary general hos-pitals in Jiangsu Province is relatively low,but there are significant differences among different hospitals.There-fore,perioperative prevention and control measures should be carried out based on the epidemiological characteristics of patients.

Objective To analyze the correlation between Ki-67 expression in tumor tissue and ultrasound features of patients with mass breast cancer.Methods A total of 90 patients(90 masses)with mass breast cancer admitted to Xinxiang Central Hospital from January 2020 to December 2022 were selected and divided into the Ki-67 high expression group(n=53)and Ki-67 low expression group(n=37)according to the expression of Ki-67 in tumor tissue.The qualitative and quantitative characteristics of contrast-enhanced ultrasound(CEUS),shear wave elastography(SWE)and color doppler flow imaging(CDFI)were compared between the two groups,and their correlation with Ki-67 expression in patients with mass breast cancer was analyzed by multivariate logistic regression.Results The proportion of CEUS perfusion defects patients in the Ki-67 high expression group was significantly higher than that in the Ki-67 low expression group(P＜0.05).There was no significant difference in CEUS margin,homogeneity,enhancement level,post-enhancement lesion range and direction between the two groups(P＞0.05).The maximum intensity,rise time,and half time in the Ki-67 high expression group were significantly higher than those in the Ki-67 low expression group(P＜0.05).There was no significant difference in arrival time,time to peak,and mean transit time between the two groups(P＞0.05).The proportion of hard ring signs in SWE of patients in the Ki-67 high expression group was significantly higher than that in the Ki-67 low expression group(P＜0.05),while there was no significant difference in the proportion of SWE black hole signs between the two groups(P＞0.05).The elastic modulus ratio between lesions to surrounding parenchyma of patients in Ki-67 high expression group was higher than that in the Ki-67 low expression group(P＜0.05).There was no significant difference in the maximum,average,and minimum elastic modulus between the two groups(P＞0.05).In the Ki-67 high expression group,the proportion of patient where tumor size under CDFI was 2-5 cm,and the proportion of patients with burrs on the lesion edge were higher than those in the Ki-67 low expression group(P＜0.05).There was no significant difference in the shape,location and calcification of the lesions under CDFI between the two groups(P＞0.05).Perfusion defect,hard ring sign and edge burr were associated with high Ki-67 expression in patients with mass breast cancer(P＜0.05).Conclusion Ultrasonographic features of mass breast cancer can predict Ki-67 expression.Perfusion defect,hard ring sign,and edge burr are related to Ki-67 positive expression.

Objective:To analyze the expression and prognosis of B-cell lymphoma 7 protein family member A (BCL7A) in hepatocellular carcinoma, as well as the effect and mechanism of BCL7A expression on the invasion and migration of hepatocellular carcinoma cells.Methods:The cancer tissues and adjacent tissues of 40 patients with hepatocellular carcinoma who underwent radical hepatobiliary resection in the Department of Hepatobiliary Surgery, Affiliated Hospital of Nantong University from November 2017 to March 2018 were prospectively collected for protein extraction, including 29 males and 11 females, aged (58.5±10.4) years. The information of 374 cases of hepatocellular carcinoma and 50 cases of adjacent tissues were downloaded from The Cancer Genome Atlas (TCGA) database, and the hepatocellular carcinoma cell lines Hep3B and SMMC-7721 were transfected with overexpressing BCL7A plasmid and empty vector plasmid (negative control), respectively. Western blotting and immunohistochemistry were used to detect the expression of BCL7A, and Western blotting was also used to detect the expression of proteins related to epithelial-mesenchymal transition (N-cadherin, E-cadherin, snail). Transwell and cell scratch assays were used to detect cell invasion and migration.Results:Compared with adjacent tissues, the mRNA expression of BCL7A in 50 patients with hepatocellular carcinoma in TCGA was significantly increased ( t=13.38, P<0.001). According to the median mRNA expression level of BCL7A, 374 patients were divided into BCL7A high expression group ( n=187) and low expression group ( n=187), and the cumulative survival rate of BCL7A high expression patients was lower than that of low expression group, and the difference was statistically significant ( χ2=6.95, P=0.009). Western blot was used to detect the relative expression of BCL7A protein in cancer tissues, and found it was higher compared to adjacent tissues. Compared with the negative control group, the number of cells invaded by the BCL7A overexpression group of hepatoma cells Hep3B and SMMC-7721 was more than the negative control group respectively, (153.7±1.3) vs (63.7±4.7) and (307.7±25.14) vs (72.3±12.5), and the differences were statistically significant ( t=7.97, 8.38, both P=0.001) .The results of the cell scratch assay were consistent with the results of the Transwell invasion assay. The expressions of N-cadherin and snail in the BCL7A overexpression group were higher than those in the negative control group, and the E-cadherin was lower, and the difference was statistically significant (all P<0.05). Conclusions:The expression of BCL7A in cancer tissues of patients with hepatocellular carcinoma is elevated and is associated with poor prognosis. BCL7A may promote hepatocellular carcinoma cell metastasis and invasion by promoting epithelial-mesenchymal transition.

Objective: To observe and compare the clinical effects of different electroacupuncture waveforms on primary dysmenorrhea. Methods: This was a prospective, randomized, three-group, parallel-controlled trial. Participants with primary dysmenorrhea were randomly divided into dense-sparse wave, continuous wave, and discontinuous wave groups in a 1:1:1 ratio. Two lateral Ciliao (BL 32) points were used. All three groups started treatment 3–5 days before menstruation, once a day for six sessions per course of treatment, one course of treatment per menstrual cycle, and three menstrual cycles. The primary outcome measure was the proportion with an average visual analog scale (VAS) score reduction of ≥50% from baseline for dysmenorrhea in the third menstrual cycle during treatment. The secondary outcome measures included changes in dysmenorrhea VAS scores, Cox Menstrual Symptom Scale scores and the proportion of patients taking analgesic drugs. Results: The proportion of cases where the average VAS score for dysmenorrhea decreased by ≥50% from baseline in the third menstrual cycle was not statistically significant (P > .05). Precisely 30 min after acupuncture and regarding immediate analgesia on the most severe day of dysmenorrhea, there was a statistically significant difference in the dense-sparse wave group compared with the other two groups during the third menstrual cycle (P < .05). Additionally, there was a statistically significant difference between the dense-sparse wave and discontinuous wave groups 24 h after acupuncture (P < .05). Conclusions Waveform electroacupuncture can alleviate primary dysmenorrhea and its related symptoms in patients. The three groups showed similar results in terms of short- and long-term analgesic efficacy and a reduction in the number of patients taking analgesic drugs. Regarding achieving immediate analgesia, the dense-sparse wave group was slightly better than the other two groups.

Objective: To investigate the effects of a ketogenic diet (KD) alone and in combination with resistance training (KD+RT) on body composition and glucolipid metabolism of obese and female college students, and to provide a theoretical basis for the application of KD+RT in obese patients. Methods: Totally 45 obese and female college students in Wuyi University were recruited and randomly divided into KD group ( n =23) and KD+RT group ( n =22) in September 2021. After received training for 4 weeks, the changes of body composition and glucose and lipid metabolism of obese and female college students were compared before and after intervention. Results: Both a 4 week KD and KD+RT led to decreases in weight, BMI, body fat mass, body fat percentage, waist to hip ratio, visceral fat area of obese female college students ( t =16.19, 16.21, 12.42, 7.99, 2.10, 6.37; 18.82, 18.02, 17.80, 10.72, 3.41, 7.59, P <0.01). The change of muscle mass was decreased in KD group( t=4.12, P <0.01), but there was no statistically significant difference in KD+RT group( P >0.05). Both a 4 week KD and KD+RT significantly reduced the levels of the fasting blood glucose, fasting insulin, glycosylated hemoglobin and triglyceride (TG) of obese female college students ( t =10.15, 8.94 , 6.94, 7.63; 9.23, 12.75, 9.85, 9.09, P <0.01), and increased the high density lipoprotein (HDL) level( t =-7.36, -5.22, P <0.01). However, only KD+RT group had a significant decrease in the level of LDL ( t =5.27, P <0.01), and there was no significant change in the level of TC both groups ( P >0.05). After the intervention, there was no statistically significant difference between the KD+RT group compared to the KD group ( P >0.05), except for a significant decrease in triacylglycerol ( t =2.51, P < 0.05 ). Conclusion Both a short term KD and KD+RT show beneficial changes in body composition and glucolipid metabolism in obese female college students. However, the KD+RT is superior to a KD in maintaining muscle mass and reducing the effects of lipid metabolism.
