INTRODUCTION
Hyperthyroidism was thought to lower thyroid cancer risk due to TSH suppression, potentially leading to overlooked diagnoses. This study examines clinical factors linked to thyroid cancer in hyperthyroid patients who have undergone thyroidectomy.
OBJECTIVEThis study determined the clinical factors associated with malignancy among patients with hyperthyroidism who underwent thyroidectomy in a tertiary hospital.
METHODSThis analytical cross-sectional study reviewed electronic biopsy results of adult patients who underwent thyroidectomy from January 2009 to December 2019 for hyperthyroidism secondary to Graves’ Disease, Solitary Toxic Adenoma or Multinodular Toxic Goiter. It considered factors linked to thyroid cancer, its prevalence, and clinical features associated with aggressive tumor behavior.
RESULTSSixty hyperthyroid patients who underwent thyroidectomy were included, 12 of whom have thyroid cancer. Each increase in the initial free thyroxine (FT4) leads to increased likelihood of thyroid cancer by 1.02 times (95% CI 1.001-1.03, p=0.044). The presence of thyroid nodule is associated with 24 times (95% CI 2.67-3275.62, p=0.002) higher risk of thyroid cancer, while every unit increase in mm for nodule diameter increases thyroid cancer odds by 1.04 times (95% CI 1.01-1.07, p=0.022). An FNAB pre-op diagnosis of malignancy is associated with having histopathologic diagnosis of thyroid cancer increased by 40 times (95% CI 2.42-6668.98, p=0.007). Although aggressive tumor behavior was noted among those with a younger age on average (36.35 vs 46.75 years), higher initial FT4 (95.97 vs 23.55 pmol/L), and those with sizeable diameter of multinodular goiter (95 mm vs 20 mm), only the high FT4 was statistically significant.
CONCLUSIONInitial FT4, thyroid nodules, nodule size, and pre-operative FNAB finding of a malignancy were the factors associated with thyroid cancer in hyperthyroid patients who underwent thyroidectomy. Furthermore, those with aggressive tumor behavior had higher initial FT4 levels.

BACKGROUND
Intraoperative transfusion for gynecologic surgery, when appropriately used, can improve patient outcomes. However, when utilized incorrectly, blood transfusion can worsen patient outcomes and increase patient cost. This study aimed to evaluate the blood transfusion practices of tertiary hospitals in the Philippines.
METHODSThe study utilized a cross-sectional design wherein prospective data were gathered through multiple sources across seven tertiary-level hospitals. Women admitted to undergo gynecologic surgery were recruited based on a set of criteria. A chart review was conducted, and blood utilization indices were calculated. Outcomes were compared between public versus private facilities and transfused versus nontransfused patients.
RESULTSAmong 514 patients, 79.7% underwent cross-matching and 75.1% received transfusions. Adverse events were rare, with no transfusion-related deaths. The overall crossmatch-to-transfusion ratio (C/T ratio) was 2.8, exceeding the 2.5 optimal benchmark; all public hospitals recorded a C/T ratio >2.5, whereas private centers had more efficient usage. Six hospitals met acceptable benchmarks for transfusion probability and transfusion index. Open abdominal procedures, particularly hysterectomy, accounted for the most blood used. Transfused patients had longer operative times, greater blood loss, lower preoperative hemoglobin, and more frequently involved resident physicians in training. Public hospitals recorded higher cross-match and transfusion rates, greater resident physician participation, and broader use of general anesthesia.
CONCLUSIONResults of the study highlight the importance of monitoring blood transfusion parameters to optimize blood utilization. The observed differences between public and private institutions in the country highlight the urgent need for standardized and evidence-based practice to ensure efficient transfusion protocols nationwide.

Polycystic ovary syndrome (PCOS) is a common endocrine and metabolic disorder affecting a substantial proportion of women of reproductive age. It is frequently associated with ovulatory dysfunction, infertility, and an increased risk of chronic metabolic diseases. A hallmark pathological feature of PCOS is the arrest of follicular development, closely linked to impaired intercellular communication between the oocyte and surrounding granulosa cells. Transzonal projections (TZPs) are specialized cytoplasmic extensions derived from granulosa cells that penetrate the zona pellucida to establish direct contact with the oocyte. These structures serve as essential conduits for the transfer of metabolites, signaling molecules (e.g., cAMP, cGMP), and regulatory factors (e.g., microRNAs, growth differentiation factors), thereby maintaining meiotic arrest, facilitating metabolic cooperation, and supporting gene expression regulation in the oocyte. The proper formation and maintenance of TZPs depend on the cytoskeletal integrity of granulosa cells and the regulated expression of key connexins, particularly CX37 and CX43. Recent studies have revealed that in PCOS, TZPs exhibit significant structural and functional abnormalities. Contributing factors—such as hyperandrogenism, insulin resistance, oxidative stress, chronic inflammation, and dysregulation of critical signaling pathways (including PI3K/Akt, Wnt/β‑catenin, and MAPK/ERK)—collectively impair TZP integrity and reduce their formation. This disruption in granulosa-oocyte communication compromises oocyte quality and contributes to follicular arrest and anovulation. This review provides a comprehensive overview of TZP biology, including their formation mechanisms, molecular composition, and stage-specific dynamics during folliculogenesis. We highlight the pathological alterations in TZPs observed in PCOS and elucidate how endocrine and metabolic disturbances—particularly androgen excess and hyperinsulinemia—downregulate CX43 expression and impair gap junction function, thereby exacerbating ovarian microenvironmental dysfunction. Furthermore, we explore emerging therapeutic strategies aimed at preserving or restoring TZP integrity. Anti-androgen therapies (e.g., spironolactone, flutamide), insulin sensitizers (e.g., metformin), and GLP-1 receptor agonists (e.g., liraglutide) have shown potential in modulating connexin expression and enhancing granulosa-oocyte communication. In addition, agents such as melatonin, AMPK activators, and GDF9/BMP15 analogs may promote TZP formation and improve oocyte competence. Advanced technologies, including ovarian organoid models and CRISPR-based gene editing, offer promising platforms for studying TZP regulation and developing targeted interventions. In summary, TZPs are indispensable for maintaining follicular homeostasis, and their disruption plays a pivotal role in the pathogenesis of PCOS-related folliculogenesis failure. Targeting TZP integrity represents a promising therapeutic avenue in PCOS management and warrants further mechanistic and translational investigation.

ObjectiveTo explore the possible mechanism of Bimin Formula (鼻敏方) in treating lung-spleen qi deficiency syndrome of allergic rhinitis (AR) with high mucin secretion. MethodsThirty-four SD rats were randomly divided into a blank group (8 rats), a model group (8 rats), a low-dose Bimin Formula group (8 rats), and a high-dose Bimin Formula group (10 rats). Except for the blank group, the other groups were subjected to AR lung-spleen qi deficiency rat models induced by smoking, gavage of Ginkgo biloba leaf extract, and ovalbumin. After modeling, rats in the low- and high-dose Bimin Formula groups were given Bimin Formula concentrate (concentration of 2.16 g/ml) by gavage at doses of 1.08 g/100 g and 2.16 g/100 g, respectively, while rats in the model group were given 0.5 ml/100 g of normal saline by gavage, once daily for 28 days; the blank group was not intervened. Behavioral assessments were performed after intervention. ELISA was used to detect the levels of peripheral blood total immunoglobulin E (IgE). HE staining was used to observe the pathological changes of nasal mucosa epithelium in rats, while immunohistochemistry was used to detect the expression of transmembrane protein 16A (TMEM16A) and mucin 5AC (MUC5AC) protein in nasal mucosa. Western Blot was used to detect the expression of nuclear factor kappa B (NF-κB) protein, and RT-PCR was used to detect the expression of TMEM16A, MUC5AC, and NF-κB mRNA in nasal mucosa. ResultsHE staining showed that the nasal mucosa epithelial cell structure in the blank group was intact without shedding, swelling, or necrosis; the nasal mucosa epithelial tissue of rats in the model group was thickened and partially shed, with infiltration of eosinophils and lymphocytes visible; the pathological changes in nasal mucosa tissue of rats in the high- and low-dose Bimin Formulagroups were improved, and more improvement was showen in the high-dose group. Compared with those in the blank group, the behavioral scores and peripheral blood total IgE levels of rats in the model group significantly increased, as well as the expression of TMEM16A, MUC5AC, and NF-κB proteins and mRNA in nasal mucosa (P<0.05 or P<0.01). Compared with those in the model group, the behavioral scores and peripheral blood total IgE levels of rats in the high-dose Bimin Formula group decreased, and the expression of TMEM16A, MUC5AC, and NF-κB proteins and mRNA in nasal mucosaalso decreased (P<0.05 or P<0.01); the behavioral scores and peripheral blood total IgE levels of rats in the low-dose Bimin Formula group were reduced, and the expression of TMEM16A and MUC5AC proteins and mRNA in nasal mucosa, as well as the expression of NF-κB protein decreased (P<0.05 or P<0.01), but the difference in NF-κB mRNA expression was not statistically significant (P>0.05). Compared with the low-dose Bimin Formula group, the expression of NF-κB protein in the high-dose group decreased (P<0.01). ConclusionBimin Formula may improve the symptoms and high mucus secretion of AR lung-spleen qi deficiency by regulating the TMEM16A/NF-κB/MUC5AC signaling pathway in nasalmucosa.

Objective:To investigate the clinical features and prognosis of male with anti-melanoma differentiation-associated gene 5 (MDA5) autoantibody.Methods:The clinical data of 246 patients with DM and anti-MDA5 autoantibodies hospitalized by Jiangsu Myositis Cooperation Group from 2017 to 2020 were collected and retrospectively analyzed. Chi-square test was performed to compared between counting data groups; Quantitative data were expressed by M ( Q1, Q3), and rank sum test was used for comparison between groups; Single factor survival analysis was performed by Kaplan-Meier method and Log rank test; Cox regression analysis were used for multivariate survival analysis. Results:①The male group had a higher proportion of rash at the sun exposure area [67.1%(47/70) vs 52.8%(93/176), χ2=4.18, P=0.041] and V-sign [50.0%(35/70) vs 30.7%(54/176), χ2=8.09, P=0.004] than the female group. The male group had higher levels of creatine kinase [112(18, 981)U/L vs 57 (13.6, 1 433)U/L, Z=-3.50, P<0.001] and ferritin [1 500 (166, 32 716)ng/ml vs 569 (18, 14 839)ng/ml, Z=-5.85, P<0.001] than the female group. The proportion of ILD [40.0%(28/70) vs 59.7%(105/176), χ2=7.82, P=0.020] patients and the red blood cell sedimentation rate[31.0(4.0, 101.5)mm/1 h vs 43.4(5.0, 126.5)mm/1 h, Z=-2.22, P=0.026] in the male group was lower than that of the female group, but the proportion of rapidly progressive interstitial lung disease (PR-ILD) [47.1%(33/70) vs 31.3%(55/176), χ2=5.51, P=0.019] was higher than that of the female group. ②In male patients with positive anti-MDA5 antibodies,the death group had a shorter course of disease[1.0(1.0, 3.0) month vs 2.5(0.5,84) month, Z=-3.07, P=0.002], the incidence of arthritis [16.7%(4/24) vs 42.2%(19/45), χ2=4.60, P=0.032] were low than those in survival group,while aspartate aminotransferase (AST)[64(22.1, 565)U/L vs 51(14,601)U/L, Z=-2.42, P=0.016], lactate dehydrogenase (LDH) [485(24,1 464)U/L vs 352(170, 1 213)U/L, Z=-3.38, P=0.001], C-reactive protein (CRP) [11.6(2.9, 61.7) mg/L vs 4.95(0.6, 86.4) mg/L, Z=-1.96, P=0.050], and ferritin levels [2 000(681, 7 676) vs 1 125 (166, 32 716)ng/ml, Z=-3.18, P=0.001] were higher than those in the survival group, and RP-ILD [95.8%(23/24) vs 22.2%(10/45), χ2=33.99, P<0.001] occurred at a significantly higher rate. ③Cox regression analysis indicated that the course of disease LDH level, and RP-ILD were related factors for the prognosis of male anti-MDA5 antibodies [ HR (95% CI)=0.203(0.077, 0.534), P=0.001; HR (95% CI)=1.002(1.001, 1.004), P=0.003; HR (95% CI)=95.674 (10.872, 841.904), P<0.001]. Conclusion:The clinical manifestations of male anti-MDA5 antibody-positive patients are different from those of female. The incidence of ILD is low, but the proportion of PR-ILD is high. The course of disease, serum LDH level, and RP-ILD are prognostic factors of male anti-MDA5 antibody-positive patients.

Objective We aimed to investigate the effects of Biejiajian Pills on MHCC-97H hepatoma cells and whether Biejiajian Pills regulate the epidermal growth factor receptor (EGFR)/mitogen-activated protein kinase (MAPK)/extracellular signal-regulated kinase (ERK) signaling pathway through miR-885-5p.Methods SPF SD rats (n = 10) were randomly divided into the blank group and the Biejiajian Pills (1.1 g/kg) group to prepare blank and Biejiajian Pills-containing serum. MHCC-97H cells in the logarithmic growth phase were divided into the model group, blank serum groups with different concentrations (5%, 10%, 15%, and 20%), the serum containing Biejiajian Pills group, and the blank group without cells. Cell proliferation was detected by the CCK-8 assay, and the optimal intervention time and concentration of drug-containing serum were screened. MHCC-97H cells were divided into the blank control group (no intervention), the Biejiajian Pills-containing serum group (20% Biejiajian Pills-containing serum), the miR-885-5p mimics group (transfected with miR-885-5p mimics), the miR-NC group (transfected with miR-885-5p NC), and the Biejiajian Pills-containing serum + miR-885-5p mimics group (treated with 20% Biejiajian Pills-containing serum and transfected with miR-885-5p mimics). Cells in each group were cultured for 72 hours. A dual luciferase reporter assay was conducted to verify the targeting relationship between miR-885-5p and EGFR. Cell proliferation was detected by the CCK-8 assay, cell migration and invasion abilities were detected by the cell scratch assay and the Transwell invasion assay. Annexin V-APC/PI double staining was performed to detect the apoptosis level, and real-time fluorescence quantitative PCR (RT-qPCR) analysis was conducted to determine the mRNA expression levels of miR-885-5p, EGFR, MEK, and ERK1/2. The expression levels of EGFR, p-EGFR, MEK, p-MEK, ERK1/2, p-ERK1/2, matrix metalloproteinase 1 (MMP1), and CyclinD1 were determined by Western blotting analysis. The subcutaneous tumor model of MHCC-97H hepatoma cells in nude mice was established by subcutaneous injection to observe the inhibitory effect of Biejiajian Pills of different doses(0.55,1.1,2.2 g/kg).Results The optimal concentration and intervention time of Biejiajian Pills-containing serum were 20% and 72 hours, respectively. Meanwhile, the dual luciferase reporter assay showed that miR-885-5p could directly target EGFR. No statistical significances between the blank control group and the miR-NC group were observed (P>0.05). Compared with the blank control group, the proliferation rates of MHCC-97H hepatoma cells in the Biejiajian Pills-containing serum group, the miR-885-5p mimics group, and the Biejiajian Pills-containing serum + miR-885-5p mimics group were significantly decreased (P<0.01), and their migration and invasion abilities were significantly decreased (P<0.05, P<0.01). At the same time, the protein expression levels of CyclinD1 and MMP1, which are closely related to cell proliferation and invasion, were significantly downregulated (P<0.05, P<0.01). The proportions of late apoptotic cells and the proportion of total apoptotic cells were significantly increased (P<0.01). In the Biejiajian Pills-containing serum group, the miR-885-5p mimics group, and the Biejiajian Pills-containing serum + miR-885-5p mimics group, miR-885-5p mRNA was significantly upregulated (P<0.01) and EGFR, MEK, and ERK1/2 were significantly downregulated at the mRNA level (P<0.05, P<0.01). EGFR, MEK, and ERK1/2 phosphorylation was inhibited (P<0.01), and the Biejiajian Pills-containing serum + miR-885-5p mimics group showed the best effect (P<0.05, P<0.01). The subcutaneous liver tumor model in nude mice verified that Biejiajian Pills can inhibit tumor growth in a dose-dependent manner. Conclusion Biejiajian Pills can promote apoptosis of MHCC-97H hepatoma cells and inhibit their proliferation, invasion, and migration. The mechanism may be related to the targeted regulation of the EGFR/MAPK/ERK signaling pathway by miR-885-5p.
