This paper reported the diagnosis and treatment of a case of inguinal ectopic pregnancy. The patient, a 34-year-old female, had her last menstrual period on June 28, 2024. After amenorrhea, serum human chorionic gonadotropin (hCG) levels continued to rise (the highest was 13 193 U/L). However, repeated transvaginal ultrasound examinations failed to locate the implantation site of the gestational sac. Given the patient's inguinal pain, focused ultrasonography was performed in the inguinal region, revealing an ectopic pregnancy mass, which was subsequently surgically removed. Pathological analysis confirmed the diagnosis of inguinal ectopic pregnancy.

Objective:To analyze the relationship between plasma uranium concentration and renal injury.Methods:A case-control study was conducted in Hunan province, involving 102 renal injury cases and 102 matched controls. The association between plasma uranium concentration and renal injury was analyzed using conditional logistic regression models, and the dose-response relationship was analyzed through restricted cubic spline regression. The linear regression model and Spearman correlation were used to analyze the association between plasma uranium concentration and renal injury indicators.Results:The median of plasma uranium concentration was 8.94 ng/L in all subjects and 10.19 ng/L in the case group. The plasma uranium may be a risk factor for renal injury, with a dose-response relationship between the both representing nonlinear association ( χ2=5.15, P<0.05). The risk of renal injury was 4.21 times higher in the group exposed to highest uranium concentration than that in the group exposed to lowest uranium concentration. Plasma uranium concentration was closely related to glomerular filtration rate, serum creatinine and β 2-microglobulin ( r=0.211, -0.142, 0.195, P<0.05). Conclusions:The plasma uranium concentration is significantly associated with the renal injury, which may provide epidemiology evidence for the prevention of renal injury.

Background Exposure to uranium can result in multi-organ toxicity in humans. Some experimental studies have shown that uranium presents a damaging effect on liver, but no relevant population studies have been reported. Objective To investigate a potential association of plasma uranium exposure with liver injury. Methods The inhabitants of two representative areas of heavy metal pollution in northern and southern Hunan were selected as the research subjects. A total of 740 participants were recruited through 1∶1 paired case-control design based on a pre-determined diagnostic criterion for liver injury (defined as two or more anomalies among alanine aminotransferase, aspartate aminotransferase, and total bilirubin in the health examination) and the principle of case-control comparability. Information such as general demographic characteristics and medical history were collected through questionnaires and physical examination. Plasma uranium and liver function were determined by laboratory tests. Spearman correlation was applied to assess the association between plasma uranium concentration and liver injury indexes, and restricted cubic spline model was used to evaluate the dose-response relationship between plasma uranium concentration and liver injury. The participants were divided into four groups from Q1 to Q4 according to the quartile values of plasma uranium concentration of the control group after natural logarithmic transformation (with the Q1 group as the reference group), and the association between plasma uranium concentration and liver injury was evaluated by conditional logistic regression. Results The plasma uranium level in M (P₂₅, P₇₅) of the case group was 10.89 (6.78-18.53) ng·L⁻¹, higher than that in the control group, 9.26 (5.01-14.38) ng·L⁻¹ (P<0.001). The results of Spearman correlation analysis showed that alanine aminotransferase and aspartate aminotransferase were positively correlated with plasma uranium level (r_s=0.138, r_s=0.167; P<0.001). The restricted cubic spline model showed that the risk of liver injury increased with the increase of plasma uranium concentration (overall effect P<0.001). After adjusting for confounding factors such as gender, age, smoking, alcohol consumption, and prevalence of hypertension and hyperlipidemia, the results of conditional logistic regression analysis showed that the risks of liver injury in the Q2 group, the Q3 group, and the Q4 group were 2.043 (95%CI: 1.135-3.680), 2.246 (95%CI: 1.238-4.075), and 3.536 (95%CI: 1.955-6.397) times higher than that of the Q1 group respectively. Conclusion Plasma uranium exposure is associated with liver injury. This study is the first to provide population-level evidence of such an association.
