ObjectiveThis study aims to compare the modeling effects of submaxillary gland antigen and salivary gland antigen in the establishment of Sjögren syndrome (SS) mouse models, and to characterize the phenotypic and immunological features of these models in comparison with spontaneous SS-prone non-obese diabetic (NOD)/LtJ mice. MethodsAdult C57BL/6J mice (equal numbers of males and females) were immunized with submaxillary gland antigen or salivary gland antigen, respectively, combined with Freund's adjuvant to induce SS models. Mice immunized with phosphate-buffered saline (PBS) combined with Freund's adjuvant served as the control group. Immunization was induced via multiple subcutaneous injections in the back with antigen combined with Freund's complete adjuvant (FCA) on Days 1 and 7. A booster immunization was administered via multiple subcutaneous injections in the back with antigen combined with Freund's incomplete adjuvant (FIA) on Day 14. Female NOD/LtJ mice were used as the spontaneous SS model group, with ICR mice as the corresponding control strain for comparative analysis. Body weight, water intake, and salivary flow rate of mice were dynamically monitored for 4 weeks. At the end of the experiment, tissue and serum samples were collected, the weights of submaxillary glands, thymus, and spleen were measured, and organ indices (organ-to-body weight ratios) were calculated. Pathological morphological analysis of the submaxillary gland and spleen was performed with hematoxylin and eosin (HE) staining. Serum interleukin-17 (IL-17) level was detected using enzyme-linked immunosorbent assay (ELISA). Real-time quantitative polymerase chain reaction was used to detect the mRNA expression levels of SS type A (SSA) and SS type B (SSB) in submaxillary gland tissues. ResultsFemale mice in the submaxillary gland antigen group exhibited significantly increased water intake (P<0.05) and reduced salivary flow rate (P<0.05) compared with the female control group. No statistically significant differences were observed in the submaxillary gland index, thymus index and spleen index (P>0.05). Focal lymphocytic infiltration was observed in the submaxillary glands, and the splenic marginal zone was enlarged. Serum IL-17 levels were significantly increased (P<0.05). There was no significant difference in submaxillary gland SSA/SSB expression levels (P>0.05). Compared with the female control group, female mice in the salivary gland antigen group showed no statistically significant differences in water intake, salivary flow rate, submaxillary gland index, and spleen index (P>0.05), whereas the thymus index was significantly reduced (P<0.01). Mild inflammatory cell infiltration and glandular atrophy were observed in the submaxillary glands, and the splenic white pulp and marginal zone were slightly enlarged. Serum IL-17 levels and submaxillary gland SSB mRNA expression levels were significantly increased (P<0.01), whereas no significant change was observed in submaxillary gland SSA expression levels (P>0.05). Compared with the male control group, mild submaxillary gland atrophy was observed in male mice in the submaxillary gland antigen group, whereas no obvious changes were found in other modeling-related indicators (P>0.05). Compared with the ICR control group, NOD/LtJ model mice exhibited elevated water intake (P<0.05), significantly reduced salivary flow rate (P<0.01), no significant differences in the submaxillary gland index or spleen index (P>0.05), but a significantly increased thymus index (P<0.05). Marked focal infiltration was observed in the submaxillary glands, the splenic marginal zone was obviously enlarged, and serum IL-17 concentrations as well as submaxillary gland SSA/SSB expression levels were significantly increased (P<0.05). ConclusionSubmaxillary gland antigen and salivary gland antigen can induce SS-related features in female C57BL/6J mice. The SS-related phenotype is more pronounced in the submaxillary gland antigen group than in the salivary gland antigen group, but weaker than that in spontaneously SS-prone female NOD/LtJ mice. Immunization of male C57BL/6J mice with submaxillary or salivary gland antigens fails to induce an obvious SS phenotype.

Objective:To evaluate the feasibility of a six-step suspension technique for endoscopic lateral neck dissection (LND) through the chest-breast approach in patients with papillary thyroid carcinoma (PTC).Methods:This is a retrospective case series study.Clinical data of 81 PTC patients who underwent endoscopic LND via the chest-breast approach using the six-step suspension method at the Department of Thyroid Surgery, Shenzhen People′s Hospital were collected from January 2022 to October 2024. The cohort consisted of 15 male and 66 female patients, with age of (35.2±10.2)years (range:8.5 to 65.0 years). Key variables, including LND duration, total operative time, postoperative hospital stay, details of lymph node metastasis, postoperative complications, and follow-up data were recorded and analyzed.Results:The duration of LND was (131.8±42.2)minutes (range: 65 to 275 minutes), and the total operative time was (195.5±49.6)minutes (range: 110 to 390 minutes). The postoperative hospital stay was (4.8±1.5)days(range:3 to 15 days). The number of dissected lateral cervical lymph nodes was 32.7±10.1 (range: 11 to 54). The maximum tumor diameter was (16.1±10.1)mm(range:2 to 30 mm), while the maximum size of metastatic lymph nodes was (16.7±6.2)mm(range:7 to 30 mm). The positivity rate was 24.7% (841/3 410) in the lateral cervical+central lymph node and 16.1% (427/2 646) in the lateral cervical lymph node. Postoperative lymphatic leakage occurred in 2 patients, both of whom were successfully treated conservatively. No other significant complications were reported. During the postoperative follow-up period, which lasted for (18.3±7.4) months (range: 1.1 to 34.4 months), the mean postoperative serum thyroglobulin (Tg) level ( M(IQR)) was 0.05 (0.50) μg/L (range: 0.01 to 7.90 μg/L), with 86.4% of patients showing a Tg ≤1.00 μg/L. Through imaging evaluations, no evidence of residual disease or recurrence was detected. Conclusion:Endoscopic LND via the chest-breast approach, utilizing the six-step suspension method, maybe a feasible and effective technique with promising clinical outcomes.

Objective To explore the factors influencing cognitive dysfunction in patients with vestibular migraines.Methods The clinical data of 298 patients with vestibular migraine admitted to the Second People's Hospital of Guiyang City from January 2020 to Ja-nuary 2024 were retrospectively analyzed.The patients were divided into a cognitive impairment group(n=55)and a non-cognitive impairment group(n=243).Baseline data such as sex,age,body mass index,and educational level between the two groups of patients were matched using propensity score matching in a 1∶1 ratio.Factors influencing cognitive dysfunction in patients with vestibular migraine were screened using single-factor and multiple logistic regression analyses.Results Fifty pairs of patients were successfully matched.Single-factor and multivariate logistic regression analyses showed that migraine duration≥10 years,sleep disorders,anxiety or depression,threatened migraine,and white matter lesions were risk factors for cognitive impairment in patients with vestibular migraine(P＜0.05).Conclusion Duration of migraine,sleep disorders,anxiety or depression,threatened migraine,and white matter lesions are factors influencing cognitive dysfunction in patients with vestibular migraine.Corresponding intervention strategies can be developed for risk factors to reduce the occurrence of cognitive dysfunction and improve prognosis.

To achieve rapid and visual detection of Plasmodium vivax,a detection method based on recombinase polymerase amplification(RPA)technology and lateral flow dipstick(LFD)was established and evaluated.Targeting the conserved sequence of the P.vivax 18S rRNA gene(GenBank:DQ660817.1)as the target sequence,primers and probes were designed with Primer Premier 5,and the P.vivax recombinant plasmid(pUCPv)was constructed as the standard.A sensitive and specific RPA-LFD-based rapid visual detection method for P.vivax nucleic acids was established.The plasmid standard was serially diluted 10-fold to concentrations of 1×103,1×102,1×101,1×10?,and 1×10?1 copies/μL for sensitivity testing.To evaluate specificity,whole blood DNA samples from patients infected with Plasmodium falciparum,Plasmodium malariae,Plasmodium ovale,or Leishmania donovani,as well as healthy participants,were tested by RPA-LFD.Additionally,The assay′s accuracy was evaluated by testing whole blood DNA samples from 24 confirmed P.vivax-infected patients.This study successfully established a sensitive,specific,and rapid visual RPA-LFD method for detecting P.vivax nucleic acids.The assay can complete P.vivax detection within 20 minutes under isothermal conditions at 39 ℃,achieving a sensitivity of 1 copy/μL.There is no significant cross reaction with parasites such as other Plasmodium species and L.donovani,and the specificity is 100%.All 24 DNA samples from confirmed P.vivax patients were detected,showing a 100%detection rate.The developed RPA-LFD assay exhibits excellent sensitivity and specificity,requires only simple heating equipment,and is user-friendly.This rapid visual detection method is particularly suitable for P.vivax screening in low-resource settings.

Aim To explore the neuroprotective effects of salidroside on Parkinson's disease(PD)through modulation of inflammatory responses and the underly-ing mechanisms.Methods Mice were divided into five groups:healthy control group,1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine(MPTP)disease group,low-dose Rhodioloside intervention group,medium-dose salidroside intervention group,and high-dose salidro-side intervention group.MPTP-induced PD mouse model was established,and salidroside intervention was administered.Behavioral changes,inflammatory cyto-kine levels,autophagy-related protein expression,and neurons were observed through histological analysis and immunohistochemical staining.Results After MPTP treatment,mice exhibited significant behavioral chan-ges,increased pro-inflammatory cytokines,decreased anti-inflammatory cytokines,reduced autophagy-related proteins,and evident pyroptosis.Salidroside interven-tion alleviated these changes in a dose-dependent man-ner.Conclusions Salidroside exerts neuroprotective effects on PD by alleviating inflammatory responses and promoting autophagy,thereby protecting neurons.

Objective:To investigate the relationship between fibroblast growth factor receptor-2(FGFR2)gene polymorphisms and the risk of breast cancer and its protein expression in Han women from Heilongjiang,China.Meth-ods:Using the Snapshot technique for multiplex single nucleotide polymorphism genotyping,the polymorphisms rs3135718 and rs1219648 of FGFR2 were analyzed in 747 breast cancer patients and 716 healthy controls.Logistic re-gression was used to examine the association between these genotypes and breast cancer susceptibility.In a subset of 338 cases,immunohistochemistry was performed to assess FGFR2 protein expression,and chi-square tests was used to analyze the relationship between polymorphisms and protein expression.Results:The genotype frequencies of FGFR2 rs3135718 and rs1219648 showed significant differences between the breast cancer and control group.Logistic regression revealed that,for rs3135718,the CT,CC,and CT+CC genotypes were associated with increased breast cancer risk compared to the TT genotype(OR=1.280,95%CI:1.003-1.633;OR=1.500,95%CI:1.112-2.023;OR=1.341,95%CI:1.066-1.688).For rs1219648,the GA,GG,and GA+GG genotypes were significantly associated with higher breast cancer risk compared to the AA genotype(OR=1.352,95%CI:1.063-1.719;OR=1.826,95%CI:1.361-2.504;OR=1.475,95%CI:1.175-1.852).However,no significant association was found between FGFR2 rs3135718 and rs1219648 polymorphisms and FGFR2 protein expression(χ2=0.052,P=0.820;χ2=0.117,P=0.732).Conclusion:FGFR2 gene poly-morphisms rs3135718 and rs1219648 are significantly associated with breast cancer susceptibility in Han women from Heilongjiang,China,but these polymorphisms do not show a clear relationship with FGFR2 protein expression.

Background and Aims:Gastroesophageal reflux disease(GERD)is a common complication following sleeve gastrectomy(SG),particularly in patients with concomitant hiatal hernia,where symptoms tend to be more persistent and refractory,significantly impairing postoperative quality of life.This study aimed to evaluate the efficacy of laparoscopic hiatal hernia repair combined with gastroesophageal fixation in SG patients with severe GERD and hiatal hernia,providing clinical reference for revisional surgical strategies.Methods:The clinical data of 9 patients with severe GERD after SG who underwent laparoscopic hiatal hernia repair and gastroesophageal fixation at Huashan Hospital,Fudan University,between January 2023 and June 2024 were retrospectively analyzed.GerdQ scores,proportion of endoscopically confirmed reflux esophagitis,and proton pump inhibitor(PPI)usage were compared before and after surgery.Surgical parameters and follow-up outcomes were also recorded.Results:All patients successfully completed the surgery without major intraoperative complications,and the mean postoperative hospital stay was 5.22 d.After a mean follow-up period of 15.27 months,the GerdQ score significantly decreased from 11.67±2.00 to 7.22±1.48.The proportion of patients with GerdQ score≥8 decreased from 100.00％to 44.44％,and the rate of endoscopically confirmed GERD dropped from 88.89％to 11.11％;PPI use also significantly declined,with all differences reaching statistical significance(all P＜0.05).Conclusion:Laparoscopic hiatal hernia repair combined with gastroesophageal fixation can effectively alleviate reflux symptoms in SG patients with coexisting hiatal hernia,demonstrating favorable short-term efficacy and high safety.This approach may be a preferable surgical option for selected patients.

Objective: To investigate the potential efficacy and safety of Lutai Danshen Baishao granules (LDBG) for treating female melasma associated with kidney deficiency and blood stasis patterns. Methods: A randomized, double-blind, placebo-controlled trial was conducted at the Third Central Hospital of Tianjin, China from March to December 2023. A total of 110 female patients with melasma linked to kidney deficiency and blood stasis were enrolled and treated with either LDBG or a placebo twice daily for 60 days. Efficacy was assessed through measures such as the total melasma area, reduced melasma area, reduction rate of melasma area, melasma color score, Melasma Area and Severity Index (MASI) score, and traditional Chinese medicine (TCM) symptom score scale. Safety assessments included routine blood and biochemical tests. Results: Participants in both groups were aged 52–63 years, with no significant differences. After the 2-month intervention, the total melasma area decreased in both groups; however, a greater reduction was observed in the test group [462.50 mm2 (12.81%) vs. 100.00 mm2 (3.11%), P < .001]. Moreover, LDBG treatment significantly reduced the MASI and melasma color scores in the test group (P < .05). The total TCM symptom evaluation score significantly decreased (test group: 6.00 vs. placebo group: 7.00, P = .001), with significant relief in symptoms such as improvement in dark lips, nails, and waist soreness in the test group, compared with that in the placebo group (P < .05). Within-group comparisons revealed that TCM syndrome was significantly alleviated in the test group (P < .05). Conclusion LDBG intervention shows promising effectiveness in reducing female melasma and alleviating TCM syndromes.

Objective:To develop a treatment-related quality of life scale for Chinese patients with multiple myeloma (MM) and to test its reliability and validity.Methods:The initial scale was constructed through a literature search, Delphi expert correspondence, and cognitive testing. This study conducted a preliminary survey of 379 patients with MM and a formal survey of 865 patients from the hematology departments of 155 hospitals nationwide from February 2024 to March 2024. The final scale was obtained after conducting item analysis and reliability and validity tests on the initial scale.Results:The constructed scale contains 36 items covering six domains: physiological, psychological, social, treatment side effects, general health, and others. In the preliminary survey, the Cronbach’s alpha coefficient of each item ranged from 0.597 to 0.939, and the test-retest reliability was 0.747 ( P<0.001). Exploratory factor analysis extracted eight common factors with a cumulative variance contribution of 60.058%. In the formal survey, the Cronbach’s alpha coefficient of each item ranged from 0.484 to 0.930, and the test-retest reliability was 0.835 ( P<0.001). Confirmatory factor analysis revealed a comparative fit index of 0.750, a root-mean-square error of approximation of 0.090, and a root-mean-square residual of 0.067. Conclusion:The treatment-related quality of life scale for Chinese patients with MM designed in this study exhibited good reliability and validity, reflecting the impact of treatment on the quality of life of patients. This scale can provide a reference to clinicians for assessing the disease status of patients.
