Purpose: The aim of this study was to investigate the feasibility of an intelligent handheld ultrasound (US) device for assisting non-expert general practitioners (GPs) in detecting carotid plaques (CPs) in community populations. Methods: This prospective parallel controlled trial recruited 111 consecutive community residents. All of them underwent examinations by non-expert GPs and specialist doctors using handheld US devices (setting A, setting B, and setting C). The results of setting C with specialist doctors were considered the gold standard. Carotid intima-media thickness (CIMT) and the features of CPs were measured and recorded. The diagnostic performance of GPs in distinguishing CPs was evaluated using a receiver operating characteristic curve. Inter-observer agreement was compared using the intragroup correlation coefficient (ICC). Questionnaires were completed to evaluate clinical benefits. Results: Among the 111 community residents, 80, 96, and 112 CPs were detected in settings A, B, and C, respectively. Setting B exhibited better diagnostic performance than setting A for detecting CPs (area under the curve, 0.856 vs. 0.749; P<0.01). Setting B had better consistency with setting C than setting A in CIMT measurement and the assessment of CPs (ICC, 0.731 to 0.923). Moreover, measurements in setting B required less time than the other two settings (44.59 seconds vs. 108.87 seconds vs. 126.13 seconds, both P<0.01). Conclusion Using an intelligent handheld US device, GPs can perform CP screening and achieve a diagnostic capability comparable to that of specialist doctors.

The prevalence of Lyme disease in endogenous populations in Urumqi,Xinjiang was investigated.In total,795 serum samples were collected from residents of three townships in the surrounding area of Urumqi City from 2022 to 2023,which included 383 from Lucaogou Town,145 from Shuixigou Town,and,267 from Tori Township.Serum levels of IgG and IgM antibodies were screened with an enzyme linked immunosorbent assay(ELISA)and confirmed by western blot(WB)analysis.Clinical data of WB-positive indi-viduals were collected and comprehensive analysis was con-ducted for case diagnosis.The chi square test was used for statistical analysis of the results and the P＜0.05 was consid-ered statistically significant.In total,110(13.84％)of 795 samples were positive.The positivity rates was higher in females than males[16.26％(73/449)vs.10.69％(37/346),x2=5.076,P=0.024],while there was no significant difference among age groups(x2=2.569,P=0.766).The positivity rates for serum antibodies in Shuixigou Town,Lucaogou Town,and Tuoli Township were 17.98％(48/267),14.48％(21/145),and 10.70％(41/383),respectively,with a significantly higher rate in Tuoli Township than Lucaogou Town(x2=7.041,P=0.008).Of 110 individuals who were initially positive for IgG and IgM antibodies with the ELISA,82(10.31％)were con-firmed positive by WB analysis.In total,20(2.52％)patients were diagnosed with Lyme disease based on clinical manifesta-tions.Lyme disease is epidemic among the population in Urumqi,as the infection rate is higher than the national average.Hence,continued surveillance is recommended for prevention of Lyme disease.

AIM:This study aims to investigate the effects and mechanisms of silent information regulator 6(SIRT6)on carbon tetrachloride(CCl4)-induced liver fibrosis in mice,as well as the expression changes in the down-stream pathways of hepatic stellate cells after SIRT6 silencing.METHODS:Thirty male C57BL/6J mice were randomly divided into a normal control group(n=6)and a model group(modeling at 2,4,8,12 weeks,n=24).A liver fibrosis model in mice was prepared by intraperitoneal injection of CCl4 twice a week for 12 weeks.Serum alanine aminotransfer-ase(ALT)and aspartate aminotransferase(AST)levels were measured to assess liver injury.Hematoxylin-eosin(HE)and Masson staining were used to observe the pathological changes in mouse liver tissues.Immunohistochemical staining was conducted to detect the expression of α-smooth muscle actin(α-SMA)in the liver,Western blot analysis was used to measure the expression of liver α-SMA,SIRT6,acetyl histone H3 at Lys9(H3K9ac),acetyl histone H3 at Lys56(H3K56ac),interleukin-1β(IL-1β),and IL-18 proteins.Hepatic stellate cells-T6(HSC-T6)underwent SIRT6 gene si-lencing,divided into NC siRNA group and SIRT6 siRNA group,with Western blot performed to detect the expression of SIRT6,H3K9ac,and H3K56ac proteins.RESULTS:Compared with the normal control group,the serum ALT and AST levels in the model group were significantly increased(P<0.05);HE and Masson staining results showed that the patho-logical changes in the liver of the model group worsened over time,with an increase in collagen fiber deposition.Both im-munohistochemistry and Western blot showed that the expression of liver α-SMA significantly increased at 8 and 12 weeks in the model group(P<0.05).Western blot results showed that the expression of SIRT6 protein in the liver of all model group mice was lower than that in the normal control group(P<0.05),and decreased gradually with the progression of liv-er fibrosis;also,the expression levels of H3K9ac,H3K56ac,IL-1β,and IL-18 in the liver of the model group mice were significantly elevated at 8 and 12 weeks(P<0.05);after SIRT6 silencing,compared with the NC siRNA group,the levels of H3K9ac and H3K56ac in the SIRT6 siRNA group significantly increased(P<0.05).CONCLUSION:The deficiency of SIRT6,by abnormally increasing H3K9ac and H3K56ac,raises the expression of IL-1β and IL-18,intensifying the in-flammatory response and promoting the progression of liver fibrosis,indicating that the aberrant expression of SIRT6 is in-volved in the development of liver fibrosis.

As a classic prescription for invigorating spleen and replenishing qi, Sijunzi Decoction has a good clinical efficacy in the treatment of gastric cancer. It can improve chemotherapy resistance, reduce the toxic and side effects of chemotherapy, promote postoperative recovery, enhance immunity, improve the nutritional status of patients, improve the quality of life of patients and prevent precancerous lesions. Network pharmacology studies have shown that Sijunzi Decoction exerts anti-gastric cancer effects through multiple active ingredients, multiple targets and multiple pathways, and quercetin may be the main active component in Sijunzi Decoction to exert anti-gastric cancer effects. The main mechanisms of Sijunzi Decoction in the treatment of gastric cancer include regulating the expression of cell cycle and apoptosis-related gene proteins, and inhibiting the proliferation, migration, invasion and gastric cancer stem cell characteristics of gastric cancer cells.

AIM To explore the effects of Rosa roxburghii Radix on ulcerative colitis(UC)in rats based on pyroptosis and neutrophil extracellular traps(NETs).METHODS Rats were randomly divided into the normal group and the model group.The successfully established UC rat models by trinitrobenzene sulfonic acid(TNBS)/ethanol enema were then randomly divided into the model group,the sulfasalazine group(0.3 g/kg)and the low,medium and high dose R.roxburghii Radix groups(2,4,8 g/kg),followed by dosing of corresponding drugs by gavage.21 days later,the rats had their disease activity index(DAI)score calculated;their pathological changes of colon tissue observed by HE staining;their levels of serum interleukin(IL)-18,IL-1β and myeloperoxidase(MPO)detected by ELISA;and their protein expressions of NE,MPO,NLRP3,caspase-1 and GSDMD in colon tissue detected by Western blot and immunohistochemistry.RESULTS Compared with the normal group,the model group displayed increased DAI score(P＜0.01),increased serum levels of IL-1β,IL-18 and MPO(P＜0.01),and increased protein expressions of NE,MPO,caspase-1,NLRP3 and GSDMD in colon tissue(P＜0.01).Compared with the model group,the groups intervened with sulfasalazine,or medium,or high dose R.roxburghii Radix demonstrated with decreased DAI scores(P＜0.05,P＜0.01),decreased serum levels of IL-1β,IL-18 and MPO(P＜0.01),and decreased protein expressions of NE,MPO,caspase-1,NLRP3 and GSDMD in colon tissue(P＜0.05,P＜0.01).CONCLUSION R.roxburghii Radix may alleviate the inflammatory reaction in a rat model of UC and improve its pathological injury of colon via regulating pyroptosis and NETs.

Cardiovascular diseases(CVDs)are a leading factor driving mortality worldwide.Iron,an essential trace mineral,is important in numerous biological processes,and its role in CVDs has raised broad discussion for decades.Iron-mediated cell death,namely ferroptosis,has attracted much attention due to its critical role in cardiomyocyte damage and CVDs.Furthermore,ferritinophagy is the upstream mechanism that induces ferroptosis,and is closely related to CVDs.This review aims to delineate the processes and mechanisms of ferroptosis and ferritinophagy,and the regulatory pathways and molecular targets involved in ferritinophagy,and to determine their roles in CVDs.Furthermore,we discuss the possibility of targeting ferritinophagy-induced ferroptosis modulators for treating CVDs.Collectively,this review offers some new insights into the pathology of CVDs and identifies possible therapeutic targets.
