Hypercholesterolemia is a significant risk factor for the development of atherosclerosis. 2',3',5'-Tri-O-acetyl-N ⁶-(3-hydroxyphenyl) adenosine (IMM-H007), a novel AMPK agonist, has shown protective effects in metabolic diseases. However, its impact on cholesterol and triglyceride metabolism in hypercholesterolemia remains unclear. In this study, we aimed to elucidate the effects and specific mechanisms by which IMM-H007 regulates cholesterol and triglyceride metabolism. To achieve this goal, we used Apoe ^-/- and Ldlr ^-/- mice to establish a hypercholesterolemia/atherosclerosis model. Additionally, hepatocyte-specific Ampka1/2 knockout mice were subjected to a 5-week high-cholesterol diet to establish hypercholesterolemia, while atherosclerosis was induced via AAV-PCSK9 injection combined with a 16-week high-cholesterol diet. Our results demonstrated that IMM-H007 improved cholesterol and triglyceride metabolism in mice with hypercholesterolemia. Mechanistically, IMM-H007 modulated the AMPKα1/2-LDLR signaling pathway, increasing cholesterol uptake in the liver. Furthermore, IMM-H007 activated the AMPKα1-FXR pathway, promoting the conversion of hepatic cholesterol to bile acids. Additionally, IMM-H007 prevented hepatic steatosis by activating the AMPKα1/2-ATGL pathway. In conclusion, our study suggests that IMM-H007 is a promising therapeutic agent for improving hypercholesterolemia and atherosclerosis through the activation of AMPKα.

Objective:To evaluate the performance of the self-developed transcranial ultrasound patch probe as well as its stability and safety in clinical applications.Methods:This study was a cross-sectional study. Fifty healthy subjects in Tangdu Hospital from October to December 2023 were randomly and equally divided into two groups using a simple randomization method. The transcranial Doppler ultrasound (TCD) examinations were performed using the self-developed transcranial ultrasound patch probe and normal TCD probe alternatively in each group from squatting to sitting and then to standing posture. Two experienced sonographers (A, B) each completed one test for the same subject using the above two different probes. The differences of the ultrasound parameters of middle cerebral artery (MCA) blood flow measured by the self-developed transcranial ultrasound patch probe and the normal TCD probe in different postures (squatting, sitting, standing) were compared. At the same time, operator satisfaction with the use of the two probes was assessed in terms of time taken to obtain satisfactory images, operational comfort, and ease of handling. In addition, the subject's comfort during the examination was examined, and the signal acquisition stability of the two probes was comprehensively evaluated.Results:There was no significant difference in detection of various ultrasound parameters of MCA between using the transcranial patch probe and the normal TCD probe (all P>0.05). The overall satisfaction of transcranial ultrasound patch probe and normal TCD probe was quite similar. The transcranial ultrasound patch probe acquired favorable and stable signals. No subjects experienced adverse events/accidents during the examination of the subjects using the transcranial ultrasound patch probe as well as the normal TCD probe.Both probes had good and stable signal acquisition. Conclusions:TCD examinations could be well performed using the transcranial ultrasound patch probe, which might provide a potential new method for real-time monitoring and evaluating of cerebral blood flow of a moving subject.

Objective To investigate the origin of Biomphalaria straminea in China, so as to provide insights into assessment of schistosomiasis mansoni transmission risk and B. straminea control. Methods Guanlan River, Dasha River, Shenzhen Reservoir, upper and lower reaches of Kuiyong River, and Xinzhen River in Shenzhen, China, were selected as sampling sites. Ten Biomphalaria samples were collected from each site, and genomic DNA was extracted from Biomphalaria samples. DNA samples were obtained from 15 B. straminea sampled from 5 sampling sites in Minas Gerais State, Pará State, Federal District, Pernambuco State, and Sao Paulo State in Brazil, South America. Cytochrome c oxidase I (COI) and mitochondrial 16S ribosomal RNA (16S rRNA) genes were sampled using the above DNA templates, and the amplified products were sequenced. The COI and 16S rRNA gene sequences were downloaded from GenBank, and the sampling sites were acquired. All COI and 16S rRNA gene sequences were aligned and evolutionary trees of B. straminea were created based on COI and 16S rRNA gene sequences to identify the genetic similarity and evolutionary relationship between B. straminea samples from China and South America. Results A total of 60 COI gene sequences with a length of 529 bp and 3 haplotypes were obtained from B. straminea sampled from China. There were 165 COI gene sequences of B. straminea retrieved from GenBank, and following alignment with the above 60 gene sequences, a total of 33 haplotypes were obtained. Phylogenetic analysis showed that the three haplotypes of B. straminea from China were clustered into one clade, among which the haplotype China11 and three B. straminea samples from Brazil retrieved from GenBank belonged to the same haplotype. Geographical evolution analysis showed that the B. straminea samples from three sampling sites along eastern coasts of Brazil had the same haplotype with China11, and B. straminea samples from other two sampling sites were closely, genetically related to China11. A total of 60 16S rDNA gene sequences with approximately 322 bp in length were amplified from B. straminea in China, with 2 haplotypes identified. A total of 70 16S rDNA gene sequences of B. straminea were captured from GenBank. Phylogenetic analysis showed that Biomphalaria snails collected from China were clustered into a clade, and the haplotype China64 and the haplotype 229BS from Brazil shared the same haplotype. The 49 16S rDNA gene sequences of B. straminea from 25 sampling sites in southern Brazil, which were captured from GenBank, were included in the present analysis, and the B. straminea from 3 sampling sites shared the same haplotype with China64 in China. Geographical evolution analysis based on COI and 16S rRNA gene sequences showed that B. straminea sampled from eastern coastal areas of Brazil shared the same haplotypes in two gene fragment sequences with Biomphalaria snails collected from China. Conclusions The Biomphalaria snails in China are characterized as B. straminea, which have a low genetic diversity. The Biomphalaria snails in China have a high genetic similarity with B. straminea sampled from eastern coastal areas of Brazil, which may have originated from the eastern coastal areas of Brazil.

Objective:To summarize the clinical phenotype and genetic characteristics of children with neurodegeneration caused by UBTF gene mutations in childhood. Methods:The clinical and genetic data of 3 children with neurodegeneration in childhood diagnosed in the Department of Neurology, Children′s Hospital Affiliated to Zhengzhou University from February 2020 to January 2023 were retrospectively analyzed. All the 3 probands were found having UBTF gene mutations through the whole exome gene sequencing, and the first generation Sanger sequencing method was used to verify the UBTF gene in their family members. The variation characteristics of the UBTF gene were analyzed, and the treatment and follow-up results of the 3 children were summarized. Results:Among the 3 children with childhood onset neurodegeneration, 2 were male and 1 female, aged 9 months, 4 years and 6 months after birth, respectively. The clinical phenotypes mainly included motor retardation, speech and mental retardation, and dystonia. Among them, case 1 and case 2 had seizures, case 1 had dysphagia, feeding problems, no weight gain and ataxia. Brain MRI plain scan showed that case 1 and case 2 had different degrees of cerebral atrophy, case 1 had hypoplasia of corpus callosum, ventricle expansion and softening focus, and case 3 showed non-specific widening of the subarachnoid space. There were no abnormalities in the chromosome copy number variation and mitochondrial ring gene testing in the 3 children; the whole exon gene testing suggested the de novo missense variant in the UBTF gene [NM_014233.4: c.1414(exon14) G>A (p.Gly472Ser), c.1392(exon14)G>T(p.Lys464Asn)] and the maternal nonsense variant [NM_014233.4:c.520C>T(p.Arg174 *)], which were unreported site variants. In terms of treatment, the 3 children received comprehensive rehabilitation function training, and achieved a certain degree of language and intelligence improvement. Seizure control was effectively managed in case 1 with a single antiepileptic drug. Epileptic seizures were effectively treated and controlled in case 2 using more than 4 types of antiepileptic drugs. Conclusions:Neurodegenerative changes caused by UBTF gene mutations in childhood are relatively rare, and some cases may be accompanied with brain atrophy. De novo missense variation and maternal nonsense variation of the UBTF gene are the genetic etiology of the 3 probands.

Objective To evaluate the effect of manual massage on complications after endoscopic foam sclerotherapy injection for the treatment of internal hemorrhoids.Methods Consecutive 113 patients with grade Ⅰinternal hemorrhoids were prospectively enrolled and completed endoscopic foam sclerotherapy.The patients were randomly divided into a massage group(n=65)and a control group(n=68).Massage group performed manual perianal massage,Visual analogue scale(VAS)was used to evaluate perianal pain.The postoperative bleeding,short-term and long-term efficacy were also compared.Results The median VAS of 24 h postoperation was 1.0(0.0,3.0)in massage group,which was significantly lower than 2.0(1.0,4.0)in control group,the difference was statistically significant(P=0.014).The no bleeding rate of one week postoperation was 84.6％in massage group,which was significantly higher than 64.7％in control group,the difference was statistically significant(P=0.009).After 12 weeks,6 months and 12 months of follow-up,there were no significant differences in cure rate and remission rate between the two groups(P＞0.05).Conclusion Manual massage after endoscopic sclerosing agent injection is beneficial to relieve postoperative pain of grade Ⅰ internal hemorrhoids and reduce bleeding.

Objective:To summarize the complications and prevention after botulinum toxin type A(BTA) injection for masseter muscle hypertrophy(MMH).Methods:The clinical data of patients with masseter hypertrophy who received BTA injection in Shanxi Bethune Hospital from January 2019 to September 2021 were retrospectively analyzed. Injection method: 100 U BTA was prepared into a solution with a concentration of 50 U/ml with 2 ml 0.9% sodium chloride injection. The "safe injection zone" of the masseter muscle was marked. The anterior and posterior boundaries were the anterior and posterior edges of the masseter muscle, respectively. The upper boundary was the line from the corner of the mouth to the earlobe, and the lower boundary was the lower edge of the mandible. The injection points(3 or 4 points) were at least 1 cm away from the four borders, and 25-40 U was injected on each side. The patients were followed up after treatment, the types of complications were recorded, and the treatment measures were summarized.Results:A total of 160 patients were enrolled, including 8 males and 152 females, with a mean age of (30.6±6.2) years. All patients were followed up for 1 to 6 months. The masseter muscle of all patients was reduced to varying degrees, the lower facial lines were softer, and the facial contour was improved. The incidence of complications was 81.3%(130/160). There were four main types of complications: (1) Complications with a nonmuscular etiology include ecchymosis in 5 cases (3.1%) which resolved spontaneously in 5 to 7 days and headache occurred in 2 cases (1.3%) which disappeared in 2-3 days with proper rest. (2) The complication related to the toxin effect mainly was the decrease of masticatory power in 86 cases (53.8%), which gradually recovered with the drug metabolism for 3-12 weeks. (3) Dose-related complications include facial ptosis in 4 cases (2.5%) with 30-40 U dose per side. 2 cases without special treatment, gradually recovered in about 8-12 weeks. One patient underwent the BTA injection to raise the mandibular margin and gradually recovered about 2 weeks later. One patient recovered gradually with the treatment by Thermage in another hospital. There were 9 cases (5.6%) of paradoxical rigid masseter muscle bulge. 5 cases resolved within 1 week after supplementary injection of 4 U botulinum toxin, and the other 4 cases resolved spontaneously within 1 to 2 weeks without special treatment. (4) Complications related to the injection site include abnormal smiles in 3 cases (1.9%). Patients were instructed to practice the smile correctly and gradually recovered in 4-12 weeks. Twenty-one patients (13.1%) had sunken cheeks. One patient improved by injection of hyaluronic acid, and the other patients recovered gradually within 8-12 weeks without special treatment.Conclusion:The incidence of complications after BTA injection for MMH is high, and the manifestations are diverse. The injection should be performed in the recommended safe area of the masseter muscle. A reasonable dose and depth of injection can reduce the occurrence of complications.
