ObjectiveTo investigate the imaging features of calcium salt deposition and serological markers in patients with alveolar echinococcosis through a retrospective analysis， as well as independent risk factors for the degree of calcium salt deposition in lesions， and to provide a basis for assessing disease process. MethodsA retrospective analysis was performed for the imaging and clinical data of 107 patients with alveolar echinococcosis who were admitted to The First Affiliated Hospital of Shihezi University from December 2023 to June 2025， and according to the volume of calcium salt deposition， they were divided into non-deposition group with 16 patients， mild deposition group with 52 patients， moderate deposition group with 16 patients， and severe deposition group with 23 patients. A one-way analysis of variance or the Kruskal-Wallis H test was used for comparison of continuous data between groups， and the χ² test or Fisher’s exact test was used for comparison of categorical data between groups. The four groups were further combined into the low deposition group （no/mild deposition） and the high deposition group （moderate/severe deposition）. A binary logistic regression analysis was used to investigate the independent influencing factors for calcium salt deposition， and a predictive model was established. The receiver operating characteristic （ROC） curve was used to assess the predictive performance of the model， and the Bootstrap method was used for internal validation. ResultsThere were significant differences between the four groups in sex distribution， involvement of other sites， white blood cell count， lymphocyte percentage， fibrinogen， uric acid， sodium ion， chloride ion， and calcium ion （all P<0.05）. The univariate analysis showed that there were significant differences between the four groups in sex， involvement of other sites， white blood cell count， lymphocyte percentage， fibrinogen， alanine aminotransferase， albumin， creatinine， uric acid， sodium ion， chloride ion， and calcium ion （all P<0.1）. The multi-collinearity diagnosis showed that the VIF values for all continuous variables ranged from 1.104 to 1.760， suggesting that collinearity did not affect modeling. An ordinal logistic regression model was established based on sex， involvement of other sites， calcium ion， lymphocyte percentage， and uric acid. The multivariate analysis showed that lymphocyte percentage （odds ratio ［OR］=1.106， 95% confidence interval ［CI］： 1.041 — 1.174， P=0.001） and blood calcium level （OR=0.005， 95%CI： 0.000 —0.230， P=0.007） were independent influencing factors for the degree of calcium salt deposition. The regression equation was established as Logit（P）=8.231 + 0.100 × lymphocyte percentage -5.344 × calcium ion. The ROC curve analysis showed that the model had an area under the ROC curve of 0.716， with a Youden index of 0.353， a sensitivity of 1.000， and a specificity of 0.353. The Hosmer-Lemeshow test showed that the model had poor calibration （χ²=20.688， P=0.008）. The Bootstrap method with 1000 repeated samples showed that the estimated values of lymphocyte percentage （OR=1.106， 95%CI： 1.049 — 1.186， P=0.002） and calcium ion （OR=0.005， 95%CI： 0.000 — 0.214， P=0.010） were consistent with the original model， and the confidence intervals did not include 1， which further supported the reliability of the model. ConclusionBoth lymphocyte percentage and blood calcium level are independent influencing factors for calcium salt deposition in alveolar echinococcosis， and the degree of calcium salt deposition in alveolar echinococcosis lesions increases with the reduction in blood calcium level and the increase in lymphocyte percentage.

OBJECTIVE: The relationship between fish consumption and stroke is inconsistent, and it is uncertain whether this association varies across predicted stroke risks. METHODS: A cohort study comprising 95,800 participants from the Prediction for Atherosclerotic Cardiovascular Disease Risk in China project was conducted. A standardized questionnaire was used to collect data on fish consumption. Participants were stratified into low- and moderate-to-high-risk categories based on their 10-year stroke risk prediction scores. Hazard ratios ( HRs) and 95% confidence intervals ( CIs) were estimated using Cox proportional hazard models and additive interaction by relative excess risk due to interaction (RERI), attributable proportion (AP), and synergy index (SI). RESULTS: During 703,869 person-years of follow-up, 2,773 incident stroke events were identified. Higher fish consumption was associated with a lower risk of stroke, particularly among moderate-to-high-risk individuals ( HR = 0.53, 95% CI: 0.47-0.60) than among low-risk individuals ( HR = 0.64, 95% CI: 0.49-0.85). A significant additive interaction between fish consumption and predicted stroke risk was observed (RERI = 4.08, 95% CI: 2.80-5.36; SI = 1.64, 95% CI: 1.42-1.89; AP = 0.36, 95% CI: 0.28-0.43). CONCLUSION Higher fish consumption was associated with a lower risk of stroke, and this beneficial association was more pronounced in individuals with moderate-to-high stroke risk.

Objective:To assess the association between temperature and risk of animal injury, and identifying vulnerable populations.Methods:Based on a time-stratified case-crossover design, the number of animal injuries monitored in hospitals of Guangdong Provincial Injury Surveillance System in 2011 and 2015-2016 was included, and the daily meteorological data were derived from the fifth generation of European ReAnalysis-Land, which was produced by the European Centre for Medium-Range Weather Forecasts. Conditional logistic regression combined with a distributed lagged nonlinear model was applied to analyze the association of temperature and animal-specific injuries. We also conducted stratified analysis by region, sex, age, occupation, and location of injury occurrence.Results:There was an almost linear relationship between temperature and the occurrence of animal injury. The excess risk ( ER) of animal injury was 2.65% (95% CI: 2.27%-3.04%) for a 1 ℃ rise in temperature with much higher risk of occurrence ( ER=9.34%, 95% CI: 7.57%-11.13%) for non-mammalian injury than that for mammalian injuries ( ER=2.30%, 95% CI: 1.90%-2.70%). Stratified analysis revealed that the occurrence of animal injury was more susceptible to temperature influences in urban ( ER=2.78%, 95% CI: 2.35%-3.21%), female ( ER=2.71%, 95% CI: 2.16%-3.27%), the elderly aged 60 years and above ( ER=3.05%, 95% CI: 1.65%- 4.47%), farmer ( ER=4.66%, 95% CI: 3.03%-6.32%) and agricultural area ( ER=10.63%, 95% CI: 7.57%-13.79%) than their correspondents. In terms of mammalian injury, dog bites showed the highest risk ( ER=2.71%, 95% CI: 2.12%-3.30%). In terms of non-mammalian,snake injuries were highly influenced by temperature ( ER=16.74%, 95% CI: 11.33%-22.40%). Conclusions:The ambient temperature rises could increase the risk of animal injury with much higher risk for non-mammalian than that for mammalian injuries. Our findings suggest that global warming may increase the risk and disease burden from animal injuries.

Objective To investigate the effect of local histopathological changes of thyroid nodules after ultrasound-guided fine needle aspiration biopsy(US-FNBA)on laparoscopic thyroid surgery.Methods The clinical data of 120 patients with thyroid malignant tumors admitted to Xiaogan Hospital of Wuhan University of Science and Technology from January 2020 to December 2022 were retrospectively analyzed,and according to whether received US-FNAB before surgery they were divided into the observation group(with US-FNAB)and the control group(without US-FNAB),with 60 cases in each group.The operation time,change of parathyroid hormone(ΔPTH)before and after surgery,change of serum Ca2+concentration(serum ΔCa2+)before and after surgery,drainage volume 24 hours after surgery and incidence of complications were compared between the two groups.According to fine needle aspiration-to-surgery(FTS),the patients in the observation group were further divided into the group A(FTS≤3 days)and the group B(FTS>3 days),and the effect of US-FNAB on laparoscopic thyroid surgery was explored combined with the pathological changes of the thyroid puncture capsule of the two groups.Results The operation time of the observation group was longer than that of the control group(P<0.05),and there was no significant difference in the drainage volume 24 hours after surgery,ΔPTH,serum ΔCa2+,or proportions of facial or limb numbness,hypoparathyroidism,recurrent laryngeal nerve integrity,and hypocalcemia between the two groups(P>0.05).There was no significant difference in the operation time,ΔPTH,serum ΔCa2+,drainage volume 24 hours after surgery,hypocalcemia,recurrent laryngeal nerve integrity or hypothyroidism between the group A and group B(P>0.05).The proportion of patients with facial or limb numbness after surgery in the group A was significantly lower than that in the group B(P<0.05).Conclusion Preoperative US-FNAB for thyroid nodules may prolong the operation time in patients undergoing laparoscopic thyroid surgery,and surgical treatment in early aspiration can help decrease this effect and reduce the incidences of postoperative hypocalcemia and hypothyroidism.

Postoperative infection of internal fixation of closed fractures the lower limbs in adults represents a devastating complication, characterized by diagnostic challenges, prolonged treatment duration and high disability rates. Current management of these infections faces multiple challenges, such as difficulties in early accurate diagnosis, and various controversies about the treatment plan, leading to poor overall diagnosis and treatment results. To address these issues, based on evidence-based medicine and principles with emphasis on scientific rigor, clinical applicability and innovation, the Trauma Branch of the Chinese Medical Association, Orthopedic Branch of the Chinese Medical Doctor Association, Orthopedics Branch of the Chinese Medical Association, and Trauma Orthopedics and Polytrauma Group of the Resuscitation and Emergency Committee of the Chinese Medical Doctor Association have collaboratively organized a panel of relevant experts to develop the Guideline for diagnosis and treatment of infection after internal fixation of closed lower limb fractures in adults ( version 2025). The guideline proposed 10 recommendations, aiming to provide a foundation for standardized diagnosis and treatment of postoperative infection in adults with closed lower limb fractures.

Objective To investigate the expression of serum exosomal long non-coding RNA X chromo-some inactivation specific transcript(LncRNA XIST)and microRNA(miR)-130a-3p in gestational diabetes mellitus(GDM)patients and its relationship with pregnancy outcome.Methods A total of 149 GDM patients(GDM group)and 149 healthy pregnant women(control group)admitted to the hospital from January 2021 to January 2024 were selected.Serum exosomal LncRNA XIST,miR-130a-3p and glucose and lipid metabolism indexes of the two groups were detected and compared.The correlation of LncRNA XIST and miR-130a-3p levels with glycolipid metabolism indexes was analyzed by Pearson method.Univariate and multivariate Logis-tic regression models were used to analyze the influencing factors of pregnancy outcomes in GDM patients.Re-ceiver operating characteristic(ROC)curve was used to analyze the predictive efficacy of serum exosomal Ln-cRNA XIST and miR-130a-3p levels alone and in combination for pregnancy outcomes in GDM patients.Results Serum exosomal LncRNA XIST levels,fasting insulin(FINS),fasting blood glucose(FBG),insulin resistance index(HOMA-IR),2-hour postprandial glucose(2 hPG),total cholesterol(TC),triglyceride(TG)and low density lipoprotein cholesterol(LDL-C)levels in GDM group were higher than those in control group(P＜0.05),and the levels of miR-130a-3p and high density lipoprotein cholesterol(HDL-C)were lower than those in the control group(P＜0.05).LncRNA XIST was positively correlated with FINS,FBG,HOMA-IR,2 hPG,TC,TG and LDL-C,and negatively correlated with HDL-C(P＜0.05).miR-130a-3p was negatively correlated with FINS,FBG,HOMA-IR,2 hPG,TC,TG and LDL-C,and positively correlated with HDL-C(P＜0.05).Among the 149 GDM patients,43 cases showed adverse pregnancy outcome,accounting for 28.86％.The increase level of FBG,the increase level of LncRNA XIST and the increase of HOMA-IR were risk factors for adverse pregnancy outcome in GDM patients,while the increase of miR-130a-3p was a protec-tive factor.The ROC curve analysis showed that the predictive efficacy of combined detection was superior to that of single indicator detection.Conclusion The serum exosomal LncRNA XIST of GDM patients is highly expressed,and miR-130a-3p is lowly expressed,and the combined detection of the above indexes has a high predictive value for pregnancy outcome.

Glutamine provides carbon and nitrogen to support the proliferation of cancer cells. However, the precise reason why cancer cells are particularly dependent on glutamine remains unclear. In this study, we report that glutamine modulates the tumor suppressor F-box and WD repeat domain-containing 7 (FBW7) to promote cancer cell proliferation and survival. Specifically, lysine 604 (K604) in the sixth of the 7 substrate-recruiting WD repeats of FBW7 undergoes glutaminylation (Gln-K604) by glutaminyl tRNA synthetase. Gln-K604 inhibits SCFFBW7-mediated degradation of c-Myc and Mcl-1, enhances glutamine utilization, and stimulates nucleotide and DNA biosynthesis through the activation of c-Myc. Additionally, Gln-K604 promotes resistance to apoptosis by activating Mcl-1. In contrast, SIRT1 deglutaminylates Gln-K604, thereby reversing its effects. Cancer cells lacking Gln-K604 exhibit overexpression of c-Myc and Mcl-1 and display resistance to chemotherapy-induced apoptosis. Silencing both c-MYC and MCL-1 in these cells sensitizes them to chemotherapy. These findings indicate that the glutamine-mediated signal via Gln-K604 is a key driver of cancer progression and suggest potential strategies for targeted cancer therapies based on varying Gln-K604 status.
