AIM: To investigate the value of maximum standardized uptake value(SUVmax), extraocular muscle(EOM)diameter, and thyroid stimulating hormone receptor antibody(TRAb)in evaluating inflammatory activity in thyroid-associated ophthalmopathy(TAO).METHODS: TAO patients underwent orbital 99mTc-DTPA SPECT/CT imaging at the Affiliated Hospital of Panzhihua University between January 2023 and December 2024 were retrospectively enrolled. According to the clinical activity score(CAS), patients were classified into an active group and an inactive group. SUVmax and EOM were independently measured by three nuclear medicine physicians, and the mean values were used for analysis. Serum TRAb levels from TAO patients were measured using a fully automated electrochemiluminescence immunoassay analyzer. Nonparametric tests were used to compare differences between the two groups. Spearman correlation analysis was performed to assess the correlations of CAS with SUVmax, EOM, and TRAb. Using CAS as the reference standard, receiver operating characteristic(ROC)curves were plotted to evaluate the diagnostic performance of SUVmax, EOM, and TRAb, as well as their combination. Intraclass correlation coefficient(ICC)was used for reliability analysis to evaluate the consistency of SUVmax and EOM among the 3 measurers.RESULTS: A total of 99 patients(198 eyes)with TAO were enrolled in this study, including 38 males and 61 females, aged 16-74(46.92±11.84)y. The active group comprised 46 patients(92 eyes), aged 16-71(48.40±12.02)y, with 25 males and 21 females. The inactive group included 53 patients(106 eyes), aged 17-74(45.46±11.59)y, consisting of 13 males and 40 females. There were no statistically significant differences between the two groups in terms of gender and age(P>0.05). Statistically significant differences were observed in SUVmax, EOM, and TRAb. Compared with the inactive group, the active group showed higher SUVmax, EOM, and TRAb levels(all P<0.01). Correlation analysis showed that CAS was positively correlated with SUVmax, EOM, and TRAb(r=0.734, 0.622, and 0.404, respectively, all P<0.01). ROC curves were plotted using CAS as the reference standard, and the AUCs for SUVmax, EOM, TRAb, and their combined diagnosis were 0.874, 0.797, 0.715, and 0.892, respectively. The ICC of SUVmax and EOM were 0.925(95%CI: 0.901-0.948, P<0.001)and 0.943(95%CI: 0.907-0.964, P<0.001)respectively.CONCLUSION: Beyond CAS, there is a need to identify objective imaging and serological biomarkers. Measurements of SUVmax and EOM provide visualized and quantifiable tools for assessing TAO activity, and their combination with TRAb can further improve the accuracy of activity assessment.

Gastric ulcer （GU） is a high-incidence digestive system disease characterized pathologically by disruption of gastric mucosal integrity， with clinical features including a prolonged course and periodic recurrence. Modern medicine attributes its pathogenesis to the dynamic imbalance between aggressive and defensive factors，while traditional Chinese medicine （TCM） posits its development as closely linked to spleen deficiency. Current therapies combining acid suppressants and antibiotics face challenges such as high recurrence rates，poor mucosal healing，and adverse drug reactions. Long-term use may induce metabolic disturbances like hypergastrinemia and reduced intestinal microbiota diversity. Therefore，exploring safer and longer-lasting therapeutic strategies has become a critical focus. TCM has extensive clinical experience and unique advantages in GU prevention and treatment. Studies demonstrate that the classic formula Shenling Baizhu San exhibits therapeutic properties of "invigorating spleen and tonifying Qi to restore physiological balance and eliminating dampness and regulating middle energizer to unblock Qi movement"， enabling a holistic approach targeting both symptoms and root causes in GU with spleen deficiency as the core pathology by suppressing aggressive factors and strengthening defensive factors. Experimental research reveals its mechanisms involve enhancing the physicochemical barrier of the mucus layer，repairing epithelial barriers and microcirculation，modulating gastric acid secretion and gastrointestinal motility，and regulating microecological barriers and mucosal immunity. Clinical evidence confirms its synergistic effects in promoting ulcer healing，improving Helicobacter pylori eradication rates，and reducing recurrence risks. This review examined the etiology and pathogenesis of GU and systematically evaluated Shenling Baizhu San from three perspectives-clinical application，pharmacological effects， and experimental research-to provide insights for optimizing integrated traditional Chinese and Western medicine protocols and expanding its clinical applications.

Objective To construct a risk prediction model for the occurrence of calf muscle vein thrombosis(CMVT)in patients with spontaneous basal ganglia hemorrhage(sBGH)after surgery,and to verify the predictive effect of this model.Methods The surgical patients with sBGH who underwent neurosurgical procedures at the First People's Hospital of Huzhou(First Affiliated Hospital of Huzhou University)from January 2020 to December 2024 were enrolled as study subjects.A total of 345 patients were randomly divided into a modeling group(n=243)and a validation group(n=102).In the modeling group,patients were categorized into CMVT(n=72)and non-CMVT groups(n=171).Collected data included demographics[gender,age,body mass index(BMI)],laboratory indicators[D-dimer,activated partial thromboplastin time(APTT),fibrinogen(Fib),prothrombin time(PT),thrombin time(TT),hypersensitive C-reactive protein(hs-CRP)],and clinical data[hypertension,diabetes,smoking history,preoperative Glasgow coma scale(GCS),preoperative Caprini score,ventricular rupture,hemorrhage volume,surgical approach].Variables with statistical significance in univariate analysis were included in multivariate Logistic regression to identify CMVT risk factors and construct a nomogram model.Model fit was evaluated using the Hosmer-Lemeshow test,and predictive performance was assessed via receiver operator characteristic curve(ROC curve)analysis.Results The analysis of single factors showed that compared with the non-CMVT group,the proportion of male patients in CMVT group was significantly lower[63.9%(46/72)vs.77.8%(133/171)],while age,D-dimer,hs-CRP,Caprini score levels and bleeding volume were significantly higher[age(years):69.00(60.25,75.75)vs.55.00(67.00,74.00),D-dimer(mg/L):1.94(1.02,4.87)vs.0.89(0.48,1.74),hs-CRP(mg/L):21.94(7.50,55.87)vs.10.56(4.62,30.87),Caprini score:5(3,8)vs.3(2,5)].PT and TT were significantly prolonged[PT(s):13.10(12.10,14.13)vs.12.70(12.10,13.50),TT(s):15.25(14.23,16.06)vs.14.70(14.00,15.70)],the proportion of patients with hypertension,diabetes,ventricular rupture,and craniotomy was markedly increased[hypertension:70.8%(51/72)vs.43.9%(75/171),diabetes:25.0%(18/72)vs.7.0%(12/171),ventricular penetration:16.7%(12/72)vs.5.3%(9/171),craniotomy:59.7%(43/72)vs.35.7%(61/171)],GCS score significantly decreased[13(9,14)vs.15(13,15)].All differences were statistically significant(all P<0.05).The multivariate Logistic regression analysis showed that age[odds ratio(OR)=1.053,95%confidence interval(95%CI)was 1.018-1.090],D-dimer(OR=1.194,95%CI was 1.067-1.335),hypertension(OR=2.284,95%CI was 1.085-4.806),diabetes(OR=5.357,95%CI was 1.917-14.973),elevated preoperative Caprini score(OR=1.216,95%CI was 1.066-1.387),and craniotomy(OR=3.359,95%CI was 1.087-10.378)were all independent risk factors affecting the occurrence of CMVT in patients after sBGH(all P<0.05).The linear model was constructed using the aforementioned variables.The Hosmer-Lemeshow test results in the modeling group showedχ2=2.409,P=0.966,indicating good model fit where predicted values showed no significant difference from actual values.ROC curve analysis revealed an area under the curve(AUC)=0.846,95%CI was 0.792-0.899 for the validated model.When the optimal cut-off value was set at 0.538,the model achieved a sensitivity of 70.8%and specificity of 83.0%.In the validation set,the Hosmer-Lemeshow test showedχ2=11.300,P=0.185,indicating good model fit where predicted values showed no significant difference from actual values.ROC curve analysis demonstrated an AUC=0.893,95%CI was 0.832-0.955 for the validated model.At the optimal cut-off value of 0.674,the model achieved a sensitivity of 87.1%,specificity of 80.3%,and an accuracy of 82.4%.Conclusion The risk prediction model has good predictive performance and can provide reference for clinical evaluation of the risk of CMVT in patients with sBGH after surgery.

Objective:To investigate the clinical and pathological characteristics, treatment and prognosis of endometriosis (EM)-associated ovarian mesonephric-like adenocarcinoma (MLA).Methods:Clinical and pathological data were collected from nine patients diagnosed with EM-associated ovarian MLA at the Obstetrics and Gynecology Hospital of Fudan University between January 2022 and December 2024. Histological slides were re-reviewed, immunohistochemical examination and molecular testing were performed, and patient follow-up was conducted.Results:(1) Clinical characteristics: the median age of the nine patients was 54 years (range: 38-69 years). All patients presented with a pelvic mass; five cases also reported abdominal pain. Tumor location included five cases in the right ovary, two in the left ovary, and two involving both ovaries. International Federation of Gynecology and Obstetrics (FIGO) staging showed 3 cases at stage Ⅰ, 4 at stage Ⅱ, and 2 at stage Ⅲ. (2) Pathological features: gross examination revealed mixed solid-cystic masses with solid areas appearing gray-white or yellow-brown; the median maximum tumor diameter was 9.0 cm (range: 2.6-13.0 cm). Microscopically, tumors exhibited various architectural patterns, including tubular, glandular, papillary, slit-like, sex cord-like, glomeruloid, and solid structures, with tubular and glandular patterns being most common. Tumor cells demonstrated mild to moderate nuclear atypia. Of the 11 tumor foci in the 9 cases, 8 showed coexistence of MLA with other tumor components, such as endometrioid carcinoma, borderline endometrioid or borderline seromucinous tumors. In 1 case of MLA mixed with a borderline endometrioid tumor, both components exhibited squamous metaplasia. Immunohistochemistry showed variable expression of GATA-binding protein 3, thyroid transcription factor-1, CD 10, and calretinin, with positive rates of 9/11, 8/11, 5/11, and 3/6, respectively. Two tumor foci (2/11) exhibited focal expression of estrogen receptor and progesterone receptor. All cases displayed wild-type p53 expression. Molecular testing via next-generation sequencing in five patients revealed pathogenic mutations in the KRAS gene (5/5), with 3 cases (3/5) harboring additional pathogenic mutations in other genes. (3) Treatment and prognosis: all patients underwent surgery, supplemented by chemotherapy and (or) targeted therapy. Five patients underwent comprehensive staging surgery, four received cytoreductive surgery, and one patient received targeted therapy. The median follow-up duration was 7 months (range: 2-27 months). Three patients (3/9) experienced recurrence, and no deaths were reported during the follow-up period. Conclusions:EM-associated ovarian MLA demonstrates diverse morphological patterns and frequently coexists with other tumor types. Accurate diagnosis relies on an integrated evaluation of histomorphology, immunohistochemistry, and molecular testing. The primary treatment for EM-associated ovarian MLA is surgery, followed by adjuvant chemotherapy. Patients harboring pathogenic KRAS p.G12C mutations may benefit from targeted therapies. Ovarian MLA is an aggressive tumor, prone to recurrence in the short term, and has a poor prognosis.

Objective:To investigate the effects of CO2 intracavitary laser combined with pelvic floor magnetic stimulation on surface electromyography(sEMG)values and pelvic floor three-dimensional ultrasound parameters in female patients with stress urinary incontinence(SUI).Methods:A prospective study was conducted on 92 female SUI patients treated at the outpatient department of Meizhou People's Hospital from October 2021 to July 2023.The patients were randomly divided into an observation group and a control group(n=46 each)using a random number table.Both groups received home-based pelvic floor muscle training.The control group additionally received pelvic floor magnetic stimulation,while the observation group was treated with CO2 intracavitary laser combined with pelvic floor magnetic stimulation.The urinary leakage status,treatment efficacy,pelvic floor muscle sEMG,pelvic floor three-dimensional ultrasound parameters,quality of life,and sexual quality of life were compared between the two groups.Assessments included the International Consultation on Incontinence Questionnaire-Short Form(ICIQ-SF),the Incontinence Impact Questionnaire-Short Form(IIQ-7),and the Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire(PISQ-12).Results:1-hour leakage volume:0 g(observation group)vs.3 g(control group),24-hour leakage episodes:0 times(observation group)vs.0 times(control group),the observed differences were statistically significant(Z=-2.866,-2.355,P<0.05).Total effective rate:95.65%(observation)vs.58.70%(control),the observed differences were statistically significant(x2=4.083,P<0.05).Pelvic floor muscle sEMG(after treatment):Maximal fast contraction:(40.78±3.28)μV(observation)vs.(35.17±5.10)μV(control),Mean tonic contraction:(31.56±4.20)μV(observation)vs.(25.87±3.82)μV(control),Mean endurance contraction:(29.34±2.58)μV(observation)vs.(25.37±2.67)μV(control),all differences between the two groups were statistically significant(t=2.736,19.919,3.025,15.426,P<0.05).After treatment,both groups showed reductions in bladder neck descent(BND)during Valsalva maneuver,bladder-symphysis distance(BSD),urethral rotation angle(URA),and posterior vesicourethral angle(RVA).However,the observation group demonstrated significantly greater reductions compared to the control group(post-treatment data:observation group(24.30±3.21)mm,(2.34±0.23)mm,(56.40±5.87)°,(89.54±9.21)°;control group(26.21±3.48)mm,(3.57±0.35)mm,(60.29±6.45)°,(126.71±13.50)°.These differences were statistically significant(t=2.736,19.919,3.025,15.426,P<0.05).Similarly,both groups exhibited decreased scores on the ICIQ-SF and IIQ-7 scales,along with increased scores on the PISQ-12.Again,the observation group showed superior improvement,with statistically significant differences(t=11.478,13.168,6.631,P<0.05).Conclusion:On the basis of pelvic floor muscle training,CO2 intracavitary laser therapy combined with pelvic floor magnetic stimulation can effectively alleviate urinary incontinence symptoms in patients with female stress urinary incontinence(FSUI),enhance therapeutic efficacy,improve pelvic floor muscle strength and the stability of pelvic support structures,and promote quality of life and sexual function.

AIM To explore the differential metabolites of different aged Citrus reticulate'Chachi'and their processed cakes.METHODS Non-targeted metabolomics technology of GC-TOF-MS was used to analyze the chemical constituents.The data was processed by principal component analysis and orthogonal partial least squares discriminant analysis,and the differential metabolites were identified.RESULTS A total of 74 differential metabolites were identified,including 16 glycosides,14 organic acids and their derivatives,11 amino acids and their derivatives,and 4 flavonoids.Comparative analysis revealed 40 and 30 differential metabolites between fresh C.reticulate'℃hachi'and 3-year or 5-year aged samples,respectively.Furthermore,27 and 34 differential metabolites were identified between the 3-year or 5-year aged samples and their corresponding processed cakes,respectively.Differential metabolites among fresh,aged C.reticulate'Chachi',and processed cakes were predominantly enriched in 6 metabolic pathways,including the biosynthesis of secondary metabolites.Specifically,differential metabolites between 3-year aged C.reticulate'Chachi'and its processed cake were significantly enriched in 4 pathways,such as ABC transporters.Differential metabolites between 5-year aged C.reticulate'Chachi'and its processed cake were mainly enriched in 5 pathways,including carbon metabolism.CONCLUSION Non-targeted metabolomics technology can elucidate the chemical compositional differences among fresh/aged and processed cakes of C.reticulate'Chachi',laying a foundation for the research into C.reticulate'Chachi'aging processing techniques and the development of processed products.

Objective:To clarify the safety, repair rate, durability, and risk factors for recurrent mitral regurgitation(MR) in patients with Barlow disease(BD) who total thoracoscopic minimally invasive mitral valvuloplasty(TMVP).Methods:Clinical data, mid-term and long-term outcomes of BD patients who underwent TMVP at Guangdong Provincial People's Hospital from January 2009 to June 2022 were retrospectively analyzed. Patients were divided into a group with no MR recurrence(group A) and a group with MR recurrence(group B) according to whether recurrent MR appeared in the postoperative period, and the data of the two groups of patients were compared with each other for the risk factor analysis.Results:The repair rate of TMVP was 98.4%, and no patient died perioperatively. The median follow-up time was 3.1(1.7, 5.2) years, the follow-up rate was 95.8%, and there was no patient died. As of March 2023, 112 patients developed no recurrent MR(group A), 11 patients developed recurrent MR(group B), and 2 patients in group B underwent repeated mitral valve surgery. The left atrial diameter(LAD) and left ventricular end-systolic diameter(LVESD) were higher in group B than in group A patients[LAD: (50.9±7.7)mm vs.(43.7±8.7)mm, P=0.009; LVESD: (37.1±5.5)mm vs.(33.2±4.7)mm, P=0.011], and the percentage of tendon cord rupture was higher in group B than in group A( P=0.022), while the rest of the baseline data were not statistically significant. There was no statistically significant difference between two groups in terms of the use of different surgical techniques, aortic cross-clamp time, cardiopulmonary bypass time, and operative time. Postoperative LAD, postoperative LVESD, and postoperative left ventricular end-diastolic diameter of group B patients were higher than those of group A( P<0.05). There was no statistically significant difference in perioperative and long-term complication rates between the two groups. Multifactorial Cox regression analysis revealed that advanced age( HR=1.049, 95% CI: 0.997-1.103, P=0.066) and large preoperative LVESD( HR=1.168, 95% CI: 1.053-1.295, P=0.003) were the risk factors for postoperative recurrence MR. Conclusion:Total thoracoscopic minimally invasive BD repair is safe, which has a high success rate and good long-term results. Advanced age and large preoperative LVESD are risk factors for recurrent MR in the long term.

Intestinal microecological changes are closely related to liver cirrhosis and cirrhosis-related sarcopenia.Studies has demonstrated that interventions targeting the intestinal microbiota could contribute to the treatment of cirrhosis and cirrhosis-related sarcopenia.Here we reviewed the research progress on the alterations in intestinal microbiota during liver cirrhosis and the underlying mechanisms by which these changes impacted the development of the disease.The potential of microbiota-targeted interventions in both preventing and treating liver cirrhosis and related sarcopenia was also discussed,which might provide valuable insights into clinical diagnosis and management of the disease.

Insulin-like growth factor 2 (IGF2) is a critical endocrine mediator implicated in male reproductive physiology. To investigate the correlation between IGF2 protein levels and various aspects of male infertility, specifically focusing on sperm quality, inflammation, and DNA damage, a cohort of 320 male participants was recruited from the Women's Hospital, Zhejiang University School of Medicine (Hangzhou, China) between 1 st January 2024 and 1 st March 2024. The relationship between IGF2 protein concentrations and sperm parameters was assessed, and Spearman correlation and linear regression analysis were employed to evaluate the independent associations between IGF2 protein levels and risk factors for infertility. Enzyme-linked immunosorbent assay (ELISA) was used to measure IGF2 protein levels in seminal plasma, alongside markers of inflammation (tumor necrosis factor-alpha [TNF-α] and interleukin-1β [IL-1β]). The relationship between seminal plasma IGF2 protein levels and DNA damage marker phosphorylated histone H2AX (γ-H2AX) was also explored. Our findings reveal that IGF2 protein expression decreased notably in patients with asthenospermia and teratospermia. Correlation analysis revealed nuanced associations between IGF2 protein levels and specific sperm parameters, and low IGF2 protein concentrations correlated with increased inflammation and DNA damage in sperm. The observed correlations between IGF2 protein levels and specific sperm parameters, along with its connection to inflammation and DNA damage, underscore the importance of IGF2 in the broader context of male reproductive health. These findings lay the groundwork for future research and potential therapeutic interventions targeting IGF2-related pathways to enhance male fertility.
