Chaihu Guizhi Ganjiangtang was first recorded in the Treatise on Cold Damage （Shang Han Lun）. This prescription is composed of Bupleuri Radix， Scutellariae Radix， Cinnamomi Ramulus， Zingiberis Rhizoma， Trichosanthis Radix， Ostreae Concha， and Glycyrrhizae Radix et Rhizoma. It has the effects of soothing Lesser Yang， warming the spleen， and stimulating the generation of body fluid. It is mainly used to treat digestive tract diseases such as chronic cholecystitis （CC）， irritable bowel syndrome， and non-alcoholic fatty liver disease. Dyspepsia caused by CC presents a variety of gastrointestinal symptoms such as abdominal pain， poor appetite， postprandial fullness， aversion to greasy food， soft stool， and bitter mouth， being a type of biliary dyspepsia. In modern medicine， dyspepsia caused by CC is mainly managed by medical treatment and surgical treatment. Internal medicine mainly focuses on reducing inflammation， promoting the function of gallbladder， resolving stones， alleviating spasms， and relieving the pain for CC， demonstrating definite short-term efficacy but suffering from single effects， high recurrence rate， and poor compliance. Although surgical treatment can cure cholecystitis， it is accompanied by the increased incidence of adverse events such as abdominal pain， diarrhea， and dyspepsia. Modern clinical studies have confirmed that Chaihu Guizhi Ganjiangtang can significantly alleviate the symptoms such as abdominal pain and dyspepsia of CC patients. Pharmacological studies have found that Chaihu Guizhi Ganjiangtang mainly contains active ingredients such as Bupleuri Radix saponins， baicalin， cinnamaldehyde， gingerol， Trichosanthis Radix polysaccharide， Ostreae Concha polysaccharide， and Glycyrrhizae Radix et Rhizoma total flavonoids. Chaihu Guizhi Ganjiangtang can ameliorate the symptoms of dyspepsia caused by CC by inhibiting inflammatory responses， improving gallbladder contraction and gastrointestinal motility， regulating the bile acid-intestinal flora axis and the brain-gut axis， and modulating blood lipids through multiple targets. By reviewing the previous literature， this article summarizes the research progress in the treatment of dyspepsia caused by CC with Chaihu Guizhi Ganjiangtang and its main active ingredients as well as the pathogenesis of this disease and puts forward the shortcomings and improvement strategies for the current research. The review aims to provide a reference for the further research on Chaihu Guizhi Ganjiangtang in the treatment of dyspepsia caused by CC.

Debates persist regarding the efficacy and safety of azvudine, particularly its real-world outcomes. This study involved patients aged ≥60 years who were admitted to 25 hospitals in mainland China with confirmed SARS-CoV-2 infection between December 1, 2022, and February 28, 2023. Efficacy outcomes were all-cause mortality during hospitalization, the proportion of patients discharged with recovery, time to nucleic acid-negative conversion (T _NANC), time to symptom improvement (T _SI), and time of hospital stay (T _HS). Safety was also assessed. Among the 5884 participants identified, 1999 received azvudine, and 1999 matched controls were included after exclusion and propensity score matching. Azvudine recipients exhibited lower all-cause mortality compared with controls in the overall population (13.3% vs. 17.1%, RR, 0.78; 95% CI, 0.67-0.90; P = 0.001) and in the severe subgroup (25.7% vs. 33.7%; RR, 0.76; 95% CI, 0.66-0.88; P < 0.001). A higher proportion of patients discharged with recovery, and a shorter T _NANC were associated with azvudine recipients, especially in the severe subgroup. The incidence of adverse events in azvudine recipients was comparable to that in the control group (2.3% vs. 1.7%, P = 0.170). In conclusion, azvudine showed efficacy and safety in older patients hospitalized with COVID-19 during the SARS-CoV-2 omicron wave in China.

Purpose To explore the clinical features and CT/MRI manifestations of fibro-adipose vascular anomaly(FAVA)in children,and to analyze the misdiagnosis reason,in order to improve the diagnostic accuracy.Materials and Methods A retrospective analysis was conducted on 15 pediatric patients with pathologically confirmed FAVA in Shanghai Children's Hospital,School of Medicine,Shanghai Jiao Tong University from January 2014 to April 2024.Among them,11 underwent CT,10 underwent MRI,and 6 underwent both CT and MRI.Their CT and MRI imaging features were analyzed.Results All 15 cases presented single lesion,including eight boys and seven girls,aged from 1 year 7 months to 14 years and the median age was 8 years(6 years and 4 months to 10 years).Clinical manifestations were slow-growing masses in the soft tissues of the limbs or trunk,of which 11 cases were accompanied by pain,two cases by claudication or activity limitation and two cases by skin bruising.CT showed that the lesions were located in intramuscular,intermuscular or subcutaneous tissues;eight cases were iso-hypo-dense,three cases slightly hyper-dense or mixed-dense,ten cases showed fat density and two cases showed venous stone.MRI showed that the lesions were clearer,with fat signals visible in the internal or peripheral areas.The lesions were well defined,with fat signal inside or around the periphery,located in muscle and growing in a shuttle shape along the long axis of the muscle.The fascial tail sign was seen in six cases.All 15 cases showed significant inhomogeneous enhancement,and increased vascularization was seen around the lesions in four cases.Among the 15 pediatric patients,seven were misdiagnosed as vascular malformations,five as hemangiomas,one as angiolipoma,one as inflammatory myofibroblastoma and one was not qualitatively diagnosed.Conclusion The CT and MRI manifestations of FAVA in children have certain characteristics,but they are still prone to misdiagnosis.When intramuscular lesions are found to grow spindle-shaped along the long-axis,containing fat density/signal and blood vessels or vascular clusters,accompanied by fascial tail sign,combined with clinical manifestations such as pain,the possibility of this disease should be considered.

AIM:To investigate the preventive and therapeutic effects of sesamin(SES)on fatty liver disease in rats with hypertension combined with dyslipidemia,and to explore the potential mecha-nisms based on mRNA-seq.METHODS:Spontane-ously hypertensive rats(SHRs)were fed a high-fat,high-cholesterol diet to establish a rat model of hy-pertension combined with dyslipidemia,and then treated with SES for 16 weeks continuously.The ex-periment was divided into four groups:WKY,SHR,Model,and Model+SES(160 mg·kg-1·d-1).Blood pressure was measured using the tail-cuff method.Body weight was monitored,and body mass index was calculated.Liver morphology was detected by ultrasound,and liver thickness was measured.Liver wet weight was weighed,and liver index was calcu-lated.Liver volume was detected by the water dis-placement method.Serum triglycerides(TG),total cholesterol(TC),low-density lipoprotein cholesterol(LDL-C),high-density lipoprotein cholesterol(HDL-C),alanine aminotransferase(ALT),aspartate amino-transferase(AST),and total bile acids(TBA)were de-tected by ELISA.Liver sequencing analysis was per-formed using mRNA-seq.Liver histomorphological changes were observed by HE staining.The degree of hepatic steatosis was observed by Oil Red O stain-ing,and the degree of hepatic fibrosis was observed by MASSON staining.The mRNA expression of Al-dh1a7,Nnmt,Irs2,Pltp,and Scd was detected by q-PCR.The protein expression of Scd,Nnmt,AMPK,p-AMPK,PPARα,and PPARγ was detected by Western blotting.RESULTS:After 16 weeks of continuous SES administration to rats with hypertension combined with dyslipidemia,blood pressure was significantly reduced(P＜0.01),and body weight was decreased.Serum TG,TC,and LDL-C levels were decreased,while HDL-C levels were increased.Serum ALT and AST levels were decreased.Liver weight,organ in-dex,liver thickness,and liver volume were de-creased.The degree of hepatic steatosis and hepat-ic fibrosis was improved.A total of 545 differentially expressed mRNAs were identified in the livers of rats in each group,of which 278 were upregulated and 267 were downregulated.Among the 27 com-monly differentially expressed mRNAs,five mRNAs related to lipid metabolism were screened,namely Aldh1a7,Nnmt,Irs2,Pltp,and Scd.KEGG enrich-ment analysis showed that the enriched pathways were AMPK and PPAR.Further validation revealed that in the SES-treated group,the mRNA expression of Scd in the liver was decreased,while the mRNA expression of Nnmt was increased.The protein ex-pression of Scd was decreased,while the protein ex-pression of Nnmt,AMPK,p-AMPK,PPARα,and PPARγ was increased.CONCLUSION:SES has preven-tive and therapeutic effects on fatty liver disease in rats with hypertension combined with dyslipidemia,and its mechanism of action may be related to the reduction of Scd expression levels in the liver and the increase in the expression of Nnmt,AMPK,p-AMPK,PPARα,and PPARγ.

Objective:To analyze a Chinese pedigree with Hereditary coagulation factor Ⅻ (FⅫ) deficiency duo to variants of F12 gene and explore its molecular pathogenesis. Methods:A patient who underwent laparoscopic cystectomy at the Department of Gynecology of the First Affiliated Hospital of Wenzhou Medical University in June 2012 was selected as the study subject. Coagulation factor indexes of the proband and her family members (5 individuals from three generations) were determined. All exons, flanking sequences, 5′ and 3′ untranslated regions of the F12 gene of the proband and her family members were analyzed by direct sequencing. Three bioinformatics software was used to analyze the conservation, pathogenicity and protein model of the variant. This study was approved by the Medical Ethics Committee of the Hospital (Ethics No. 2012-17). Results:The activated partial thromboplastin time (APTT), FⅫ activity (FⅫ: C) and FⅫ antigen (FⅫ: Ag) of the proband was 180.0 s, 1.0% and 2.1%, respectively. DNA sequencing revealed that she has harbored compound heterozygous variants of the F12 gene, namely c. 712_713insT (p.Cys238Leufs *73) in exon 8 and c. 1561G>A (p.Glu521Lys) in exon 13. Her mother and younger son were heterozygous for the p. Cys238Leufs*73 variant, while her older son was heterozygous for the p. Glu521Lys variant. Bioinformatic analysis suggested that Cys238 is highly conserved and p. Cys238Leufs*73 is a pathogenic variant, which eventually resulted in a truncated protein. Conclusion:The c. 712_713insT and c. 1561G>A compound heterozygous variants of the F12 gene probably underlay the decreased FⅫ level in this pedigree, among which c. 712_713insT (NM_000505) was unreported previously.

Breast cancer cell line MDA-MB-231 was selected and treated with NET (NET group) or deoxyribonucleaseⅠ (DNase Ⅰ) digested NET (NET+DNase Ⅰ group),normal cultured MDA-MB-231 cells were used as the control group. In MDA-MB-231 cells of each group; cell proliferation ability was detected using CCK-8 assay; cell migration was detected by cell scratch assay and Transwell assay; real-time quantitative polymerase chain reaction (qRT-PCR) was used to detect the relative expressions of frizzled homolog 10 (FZD10), cyclin D1, E-cadherin and Vimentin immunofluorescence assay was performed to detect the formation of NET and the expressions of E-cadherin and Vimentin; Western blotting was used to detected the expression of FZD10-Wnt-β-catenin signaling pathway-related proteins.Results:Neutrophils were stimulated with PMA for 4 hours, and immunofluorescence assay results showed that NET exhibited fibrous reticular structure with high expression of citrullinated histone (citH3) and myeloperoxidase (MPO). The CCK-8 assay results showed that the absorbance values of cells in the control group, NET group and NET+DNase Ⅰ group were 1.25±0.06, 2.14±0.15 and 1.47±0.11, respectively, and the difference was statistically significant ( F = 80.60, P < 0.001). The results of scratch assay displayed that the percentage of wound closure in the control group, NET group and NET+DNase Ⅰ group were (36.2±1.3)%, (67.2±2.0)% and (46.3±3.2)%, respectively, and the difference was statistically significant ( F = 140.50, P < 0.001). Transwell assay indicated that the number of migrating cells in the control group, NET group and NET+DNase Ⅰ group were 317±18, 512±23 and 356±23, respectively, and the difference was statistically significant ( F = 75.39, P < 0.001). qRT-PCR assay revealed that the relative expressions of FZD10, cyclin D1 and Vimentin mRNA in the NET group were higher than those in the control group, while the relative expression of E-cadherin mRNA was lower than that in the control group, and the differences were statistically significant (all P < 0.001); the relative expressions of FZD10, cyclin D1 and Vimentin mRNA in the NET+DNase Ⅰ group were lower than those in the NET group, while the relative expression of E-cadherin mRNA was higher than that in the NET group, and the differences were statistically significant (all P < 0.001). Immunofluorescence assay indicated that the number of cells expressing Vimentin in the control group, NET group and NET+DNase Ⅰ group were 35±6, 86±13 and 51±6, respectively, and the difference was statistically significant ( F = 24.65, P = 0.001); the number of cells expressing E-cadherin were 31±4, 11±3 and 24±2, respectively, and the difference was statistically significant ( F = 38.36, P < 0.001). Western blotting results demonstrated that the relative expressions of FZD10, β-catenin and Vimentin proteins in the NET group were higher than those in the control group, while the relative expression of E-cadherin protein was lower than that in the control group; the relative expressions of FZD10, β-catenin and Vimentin proteins in the NET+DNase Ⅰ group were lower than those in the NET group, while the relative expression of E-cadherin protein was higher than that in the NET group. Conclusions:NET may promote the proliferation and migration of breast cancer cells by upregulating the expression of FZD10 and subsequently activating the Wnt-β-catenin signal pathway.

Objective:To investigate the impact and potential mechanisms of Sorbin and SH3 domain-containing protein 2 (Sorbs2) on ventricular arrhythmias in mice.Methods:In the animal experiments, mating was performed using six 8-week-old Sorbs2 +/- mice (3 males and 3 females) weighing 20-22 g. Wild-type (Sorbs2 +/+, n=8) and homozygous (Sorbs2 -/-, n=6) offspring were selected as experimental subjects through genotyping. Echocardiography was performed at 16 weeks of age to record cardiac function parameters in both groups. Resting-state and caffeine-dobutamine-induced electrocardiograms were also conducted. Real-time quantitative reverse transcription polymerase chain reaction was used to detect Sorbs2 messenger RNA expression in the heart, liver, spleen, lung, kidney, brain, small intestine, and skeletal muscle tissues of wild-type mice. Western blotting was employed to measure the protein expression levels of Sorbs2 and voltage-dependent sodium channel alpha subunit 1.5 (Na v1.5) in myocardial tissues from both groups. In the cell experiments, H9C2 cells were transfected with Sorbs2 small interfering RNA as the si-Sorbs2 group, with a corresponding si-negative control group established. Western blot was performed to detect the protein expression levels of Sorbs2 and Na v1.5 in both groups. Results:Sorbs2 was abundantly expressed in cardiac tissue. Compared with wild-type mice, homozygous mice exhibited larger left ventricular end-systolic diameter, along with lower left ventricular ejection fraction and fractional shortening ( P all<0.05). Resting-state electrocardiograms revealed no spontaneous arrhythmias in either group; however, homozygous mice showed shorter RR intervals but longer QRS and QTc intervals versus wild-type mice ( P all<0.05). Following caffeine and dobutamine induction, homozygous mice demonstrated a higher incidence of ventricular arrhythmias, longer arrhythmia duration, and higher ventricular arrhythmia scores than wild-type mice ( P all<0.05). Western blot analysis revealed that Na v1.5 protein expression was markedly lower in myocardial tissues of homozygous mice compared to wild-type mice. Similarly, si-Sorbs2-transfected H9C2 cells exhibited lower Na v1.5 protein levels compared to the si-negative control group ( P<0.05). Conclusion:Sorbs2 plays a critical role in maintaining normal cardiac electrophysiological function. Deficiency of Sorbs2 may lead to impaired cardiac function and increased susceptibility to ventricular arrhythmias in mice, which could be associated with reduced expression of Na v1.5 protein.

BACKGROUND:Wogonin is a flavonoid extracted from the root of Scutellaria baicalensis.Previous studies have shown that baicalein has protective effects against cerebral ischemia-reperfusion injury,and can also reduce blood sugar and complications in diabetic mice,but its role and mechanism in diabetic cerebral infarction remain unclear. OBJECTIVE:To explore the effect of wogonin on nerve injury in rats with diabetic cerebral infarction and its mechanism. METHODS:Sprague-Dawley rats were randomly divided into six groups:control group,model group,low-dose wogonin group,medium-dose wogonin group,high-dose wogonin group,and high-dose wogonin+Ras homolog gene family member A(RhoA)activator group.Except for the control group,the other rats were established with diabetes and cerebral ischemia models using intraperitoneal injection of streptozotocin and middle cerebral artery occlusion.Low,medium-and high-dose wogonin groups were intragastrically given 10,20,40 mg/kg wogonin,respectively;high-dose wogonin+RhoA activator group was intragastrically given 40 mg/kg wogonin and intraperitoneally injected 10 mg/kg lysophosphatidic acid;control group and model group were given the same amount of normal saline once a day for 7 consecutive days.Rats in each group were evaluated for neurological deficits and their blood glucose levels were measured after the last dose.TTC staining was applied to detect the volume of cerebral infarction.Hematoxylin-eosin staining was applied to observe pathological changes in brain tissue.ELISA kit was applied to detect tumor necrosis factor-α,interleukin-6,malondialdehyde,and superoxide dismutase levels in brain tissue.Western blot was applied to detect the protein expression of RhoA and Rho-associated protein kinase(ROCK)2 in brain tissue. RESULTS AND CONCLUSION:Compared with the control group,the neuronal structure of rats in the model group was severely damaged,with cell necrosis and degeneration,the neurological deficit score,blood glucose level,and infarct volume were significantly elevated(P<0.05),the levels of tumor necrosis factor-α,interleukin-6,and malondialdehyde,and the protein expression of RhoA and ROCK2 in brain tissue were significantly increased(P<0.05),and the superoxide dismutase level was decreased(P<0.05).Compared with the model group,the low-,medium-,and high-dose wogonin groups showed improved neuronal damage,reduced cell degeneration and necrosis,a significant reduction in neurological deficit score,blood glucose level,infarct volume,and the levels of tumor necrosis factor-α,interleukin-6,and malondialdehyde,and the protein expression of RhoA and ROCK2 in brain tissue,and an increase in the superoxide dismutase level(P<0.05).Compared with the high-dose wogonin group,the high-dose wogonin+RhoA activator group significantly weakened the improvement in the above indexes of rats with diabetic cerebral infarction(P<0.05).To conclude,wogonin can improve the blood glucose level in rats with diabetic cerebral infarction,reduce cerebral infarction and nerve injury,and its mechanism may be related to the inhibition of RhoA/ROCK signaling pathway.

Objective To explore the expression of pepsinogen Ⅰ/Ⅱ(PG Ⅰ/PG Ⅱ),nucleosome assembly protein 1 like protein 1(NAP1L1),and SERPINB5 in the serum of gastric cancer patients and their correlation with prognosis.Methods From February 2019 to February 2022,200 gastric cancer patients admitted to Zhuozhou Hospital were served as the gastric cancer group and another 100 patients with benign gastric lesions who received the treatment at Zhuozhou Hospital during the same period were served as the benign group,with 200 healthy adults as the control group.Chemiluminescence and ELISA methods were used to detect the serum PG Ⅰ/PG Ⅱ,NAP1L1,and SERPINB5.ROC curve was used to explore the diagnostic value.Kaplan-Meier method was used to explore the survival curve.Moreover,multivariate Cox method was used to analyze the factors that affected the prognosis.Results Compared with the control group,the benign group and gastric cancer group had the lower serum PGⅠ/PG Ⅱ and higher serum NAP1L1 and SERPINB5,and the difference was statistically significant(P<0.05).Compared with the benign group,the gastric cancer group had the lower serum PG Ⅰ/PG Ⅱ and higher serum NAP1L1 and SERPINB5,and the difference was statistically significant(P<0.05).PG Ⅰ/PG Ⅱ,NAP1L1,and SERPINB5 were all influential factors in gastric carcinogenesis(P<0.05).The AUC values of serum PG Ⅰ/PG Ⅱ,NAP1L1,and SERPINB5 alone in the diagnosis of gastric cancer were 0.821,0.808,and 0.833,respectively.The AUC of the combination of the three was 0.916,indicating that their combined diagnostic value was superior(Z=3.142,3.896,3.114,P<0.05).During the 3-year follow-up period of gastric cancer patients,57 cases died,accounting for 28.50%(57/200),and 143 cases survived.Patients with the high expression of PG Ⅰ/PG Ⅱ had a higher 3-year overall survival rate after the surgery compared to those with low expression,and the difference was statistically significant(χ2=7.830,P<0.05);and patients with the low expression of NAP1L1 and SERPINB5 had a higher 3-year overall survival rate after the surgery compared to those with high expression,and the difference was statistically significant(χ2=8.612,13.321,P<0.05).The serum PG Ⅰ/PG Ⅱ levels in the death group were lower than those in the survival group,and the serum NAP1L1,SERPINB5 levels were higher in patients with preoperative lymph node metastasis and TNM stage Ⅲ-Ⅳ than those in the survival group,and the difference was statistically significant(P<0.05).Elevated level of PG Ⅰ/PG Ⅱ was a protective factor for the prognosis of gastric cancer patients,while preoperative lymph node metastasis,elevated levels of NAP1L1 and SERPINB5 were risk factors affecting the prognosis of gastric cancer patients(P<0.05).Conclusion Serum PG Ⅰ/PG Ⅱ levels are decreased and NAP1L1 and SERPINB5 levels are increased in gastric cancer patients,and NAP1L1 and SERPINB5 are risk factors affecting the prognosis of gastric cancer patients,while PG Ⅰ/PG Ⅱ is a protective factor.

BackgroundChildhood represents a critical stage for cognitive development. Accurate assessment of children's cognitive abilities and understanding their developmental characteristics are essential for promoting healthy growth. However， traditional cognitive assessment methods typically rely on manual administration， presenting limitations such as low efficiency and insufficient engagement. These methods struggle to meet the assessment needs of children and are difficult to scale up for large-scale applications. ObjectiveTo develop a digital cognitive assessment tool for children， so as to provide a more convenient approach for evaluating children's cognitive functions. MethodsBased on classic psychological paradigms （Stroop Task， N-back， digit span， spatial orientation， and face-name matching）， a digital cognitive assessment tool was developed. This tool includes five tasks including color matching， shape matching， greening the home， great collector， and face-name matching， designed to assess core cognitive functions such as inhibitory control， working memory， short-term memory， spatial orientation， and semantic processing， respectively. From August 2024 to March 2025， a total of 750 students aged 9–12 yeas old from a primary school in Chengdu were enrolled and assessed using the digital cognitive assessment tool. Three months later， 40 children were randomly selected for retesting using both the digital tool and its corresponding standardized psychological paradigms. Pearson correlation analysis was conducted to examine the correlation between the pre-test and retest scores of the digital cognitive assessment tool， as well as the correlation between the digital cognitive task scores and the corresponding psychological paradigm assessment results， in order to evaluate the reliability and validity of the digital cognitive assessment tool. Additionally， differences in scores across the cognitive tasks were compared among children of different age groups and genders. ResultsA total of 699 valid samples were included. The younger age group consisted of children aged 9–10 years old （n=460）， while the older age group comprised those aged 11–12 years old （n=239）. There were 356 boys （50.93%） and 343 girls （49.07%）. In the reliability analysis， the Pearson correlation coefficients between the pre-test and retest scores of each assessment task ranged from 0.732 to 0.970 （P<0.01）， indicating statistically significant results. In the validity analysis， the Pearson correlation coefficients between each task and its corresponding standard cognitive test ranged from 0.679 to 0.988 （P<0.01）. In the color-matching task， both the main effects of age and gender were statistically significant （F=31.071， 21.198， P<0.01）. In the shape-matching task， the main effects of age， gender， and their interaction were all statistically significant （F=20.933， 5.926， 4.318， P<0.05 or 0.01）. In the greening the home task， the main effect of age was significant （F=5.243， P=0.023）. In the great collector task， the main effect of age was significant （F=33.697， P<0.01）. In the face-name matching task， only the main effect of gender was significant （F=27.016， P<0.01）. Further analysis showed that within the female group， older group scored significantly higher than younger group in five tasks（P<0.05 or 0.01）. Within the male group， younger group scored lower than older group in both the color-matching and great collector tasks （P<0.05 or 0.01）. Within the younger group， boys scored significantly higher than girls in color-matching and shape-matching tasks （P<0.01）. In the older group， girls scored significantly higher than boys in face-name matching task （P<0.01）. ConclusionThe digital cognitive assessment tool developed in this study demonstrates good reliability and validity. The development of cognitive functions in children aged 9–12 years old showed significant differences in age and gender， with specific developmental trajectories across different cognitive dimensions. At younger ages， boys outperformed girls in inhibitory control and working memory tasks， though this advantage diminished with age. At older ages， girls exhibited superior performance in semantic processing compared with boys.
