ObjectiveTo evaluate the pregnancy outcomes of assisted reproductive technology （ART） in women with a history of thyroid cancer who retained fertility intentions after completing cancer treatment. MethodsA retrospective analysis was performed on 61 patients with a history of thyroid cancer who underwent in vitro fertilization/intracytoplasmic sperm microinjection and embryo transfer （IVF/ICSI-ET）. These patients were included as the case group. A total of 122 non-cancer patients who received ART during the same period were selected as the control group using 1∶2 matching based on age and oocyte retrieval time. Baseline characteristics， outcomes of the first ART cycle， and cumulative pregnancy outcomes were compared between the two groups. ResultsThere was no significant difference in the basic data， the total amount of gonadotropin （Gn） and the days of use between the case group and the control group （P>0.05）. However， the case group had significantly fewer retrieved oocytes， mature oocytes （MII）， lower fertilization and cleavage rates， and fewer transferable and high-quality embryos， as well as fewer embryos transferred during the first cycle （P < 0.05）. However， there was no significant difference in the rate of first embryo implantation and first clinical pregnancy between the two groups （P>0.05）. In the analysis of cumulative outcomes， the two groups did not show statistically significant differences in the cumulative pregnancy rate， clinical pregnancy rate per transfer cycle， the number of oocyte retrieval cycles required per live birth， the number of embryo transfer cycles required per live birth， and the number of embryos used for each live birth （P>0.05）. However， the cumulative live birth rate was significantly lower in the case group compared to the control group （P=0.005）. ConclusionAfter treatment for thyroid cancer， when ART is used to help pregnant women， the pregnancy outcome is comparable to that of women without tumors. Individualized reproductive management and timely fertility preservation strategies are recommended to optimize reproductive outcomes in this population.

Primary biliary cholangitis （PBC） is an autoimmune liver disease characterized by intrahepatic cholestasis， while fatigue is a common symptom of PBC that significantly affects the quality of life of patients. The pathogenesis of fatigue is complex and may be associated with the factors such as cholestasis-induced inflammation， gut microbiota dysbiosis， brain structural and functional abnormalities， and mitochondrial dysfunction. At present， first-line therapies and liver transplantation have a limited effect in alleviating fatigue， and there is still a lack of standardized comprehensive assessment system. Emerging drugs and non-pharmaceutical interventions， including lifestyle modifications， have shown potential application prospects. This article systematically reviews the research advances in the clinical manifestations， pathogenesis， clinical assessment， and intervention of fatigue in PBC patients， in order to provide a reference for optimizing treatment strategies and promoting the research and development of new therapies.

BACKGROUND/OBJECTIVES: Unhealthy diets are associated with chronic stress. An allostatic load (AL) is a comprehensive physiological index that measures the chronic stress response of the body. As a healthy dietary pattern, the role of Dietary Approaches to Stop Hypertension (DASH) in the development of an AL during pregnancy remains unclear. This study examined the relationship between the DASH dietary pattern and AL during pregnancy. SUBJECTS/METHODS: This study was a prospective study. From January 2024 to November 2024, 134 pregnant women in the second trimester (23–27 weeks) and third trimester (32–36 weeks) of pregnancy who met the inclusion and exclusion criteria in the obstetrics clinic of a tertiary general hospital in Anhui Province were selected for a questionnaire survey, physical examination, and laboratory examination. The DASH dietary pattern was assessed using the DASH scoring tool, and the total AL score was calculated using nine biomarkers that represent the cardiovascular, metabolic, and immune systems. Logistic regression was used to analyze the relationship between the DASH score and AL. RESULTS: One hundred and thirty-four pregnant women were included in this study. At the second and third trimesters, 41.8% and 37% of pregnant women, respectively, were in the high AL group. The binary logistic regression results showed that the DASH score was negatively correlated with the AL in the unadjusted model (odds ratio [OR], 0.878; 95% confidence interval [CI], 0.807–0.957; P = 0.003) and adjusted model (OR, 0.878; 95% CI, 0.792–0.973; P = 0.013) in the second trimester, the DASH score was negatively correlated with the AL in the unadjusted model (OR, 0.832; 95% CI, 0.758–0.913; P < 0.001) and adjusted model (OR, 0.806; 95% CI, 0.716–0.908; P < 0.001) in the third trimester. CONCLUSION The DASH score was negatively correlated with the AL in pregnant women.A low DASH score may increase the risk of a high AL, which may have adverse effects on physical and mental health.

Objective:To investigate the value of human epididymal protein 4(HE4)combined with two-dimensional(2D)ultrasound for vagina in diagnosing the pathological classification of ovarian cancer and predicting its prognosis.Methods:The clinical data of a total of 100 patients with ovarian cancer who admitted to Hengshui Maternal and Child Health Care Hospital and Hengshui People's Hospital from April 2018 to July 2023 were retrospectively analyzed,including 98 cases with epithelial ovarian cancer and 2 cases with non-epithelial ovarian cancer.The fasting venous blood pre operation of patients was extracted in morning.The serum HE4 level was detected by enzyme-linked immunosorbent assay(ELISA).The 2D ultrasound examination was performed one week before surgery to measure the resistance index(RI),pulse index(PI),peak systolic flow velocity(PSV)and end-diastolic flow velocity(EDV)of ovarian artery.All patients were followed up immediately after they completed the last chemotherapy.All of patients were divided into a death group(n=27)and a survival group(n=73)according to their survival situation.Cox regression risk model was used to analyze prognostic influence factors of patients with ovarian cancer.Results:The serum HE4 level[449.37(28.57,2 382.24)]pmol/L in patients with epithelial ovarian cancer was significantly higher than that[55.38(17.33,79.64)]pmol/L in patients with non-epithelial ovarian cancer(U=24.752,P＜0.05).The RI,PSV and PI of ultrasonic parameters of patients with epithelial ovarian cancer were higher than those of patients with non-epithelial ovarian cancer(t=3.640,2.152,2.588,P＜0.05),respectively.The area under curve(AUC)of the receiver operating characteristic(ROC)curve of HE4 combined with 2D ultrasound for vagina was 0.936(95%CI:0.821-1.000)in identifying epithelial and non-epithelial ovarian cancer,which was larger than that of alone each examination.The ratio of the age≥60 years old,the ratio of the III-IV staging of Federation International of Gynecology and Obstetrics(FIGO),and the ratio of existing surrounding infiltration in the death group were all higher than those in the survival group,and the serum HE4 level[528.75(34.79,1 932.43)]pmol/L was higher than that[138.23(21.49,872.59)]pmol/L of the survival group,and the difference was significant(U=25.963,P＜0.05).The PSV and EDV values of the death group were all larger than those of the survival group(t=10.844,17.744,P＜0.05),and the RI and PI were all less than those of the survival group(t=19.085,13.099,P＜0.05).FIGO Ⅲ-Ⅳ staging,surrounding infiltration,HE4 level≥398.74 pmol/L,RI＜0.31,PI＜0.54,PSV≥26.12 cm/s,EDV≥16.47 cm/s were all risk factors for the prognosis of patients with ovarian cancer(HR=2.682,2.347,2.296,2.518,2.235,2.124,1.958,P＜0.05).Conclusion:HE4 combined with 2D ultrasound for vagina can improve the diagnostic accuracy of pathological classification for ovarian cancer,and can be used as an important tool to predict the prognosis of patients with ovarian cancer.

Objective:To observe changes in intestinal flora in children with anorexia and the effects of pediatric Tuina(Chinese therapeutic massage)on their intestinal flora,and to explore the relationship between alterations in intestinal flora and anorexia,as well as the therapeutic mechanisms of pediatric Tuina in treating children with anorexia.Methods:A total of 60 healthy children who underwent physical examinations were recruited as the blank group.One hundred and twenty children with anorexia were randomly divided into a Tuina group and a medication group,with 60 children in each group,according to the random number table method.The blank group received no intervention;the Tuina group was treated with pediatric Tuina therapy;the medication group was treated with Jian Wei Xiao Shi(stomach-invigorating and digestion-promoting)tablets.Both groups underwent continuous treatment for 7 d as one course,with a 1-day rest period between courses,for a total of 4 courses.Fecal samples were collected from the three groups.The intestinal flora was detected using the 16S rDNA method.Results:Before treatment,compared to the blank group,the abundance of Firmicutes in the Tuina and medication groups was significantly lower(P<0.05).After treatment,the abundance of Firmicutes in the Tuina group was significantly increased compared to before treatment(P<0.05),with no significant difference compared to the blank group(P>0.05);in the medication group,there was a trend of increased abundance of Firmicutes,but there was no significant difference compared to that before treatment in the same group(P>0.05),and the difference compared to the blank group remained significant(P<0.05).Before treatment,compared to the blank group,the abundance of Faecalibacterium prausnitzii(F.prausnitzii)in the Tuina and medication groups was significantly lower(P<0.05).After treatment,the abundance of F.prausnitzii in the Tuina group was significantly increased compared to before treatment(P<0.05),with no significant difference compared to the blank group(P>0.05);in the medication group,there was a trend of increased abundance of F.prausnitzii,but no significant difference was showed compared to before treatment in the same group(P>0.05),and the differences compared to the blank and Tuina groups were significant(P<0.05).Before treatment,compared to the blank group,the abundance of Eubacterium in the Tuina and medication groups was significantly lower(P<0.05);after treatment,the abundance of Eubacterium in both Tuina and medication groups was significantly increased compared to that before treatment(P<0.05),with no significant difference compared to the blank group(P>0.05).Before treatment,compared to the blank group,the abundance of Roseburia in the Tuina and medication groups was significantly lower(P<0.05);after treatment,the abundance of Roseburia in both Tuina and medication groups was significantly increased compared to that before treatment(P<0.05),with no significant difference compared to the blank group(P>0.05).Conclusion:The reduction of beneficial intestinal flora may be involved in the pathogenesis of pediatric anorexia.Pediatric Tuina can promote the recovery of intestinal flora balance by increasing the abundance of beneficial flora.

Objective To explore the feasibility of phase-contrast CT for three-dimensional visualization of in vitro intrahepatic vessels and necrotic foci in mouse model of acute liver injury(ALI).Methods Six clean grade male wild-type C57BL/6 mice were randomly divided into model group and control group(each n=3).The mice in model group were fed with overdose of acetaminophen to induce ALI,while those in control group were fed with the same amount of distilled water.After 24 h,the mice were all sacrificed,the livers were harvested and then fixed and dehydrated.Phase-contrast CT images of in vitro liver were acquired,sectional and three-dimensional images were reconstructed.The effect of phase-contrast CT for displaying the outline of liver and internal vessels and necrotic foci were observed,the maximum diameter and volume of necrotic foci were quantitatively analyzed,and the results of phase-contrast CT were compared with pathological findings.Results The original projection and sectional images of phase-contrast CT clearly showed the outline of in vitro liver and internal vasculatures.Necrotic foci within the liver were found in model group,but not in control group.The findings of phase-contrast CT corresponded accurately to those of pathology.Three-dimensional reconstruction images of phase-contrast CT clearly displayed intrahepatic portal vein system and hepatic vein system in both groups,and discontinuous punctate necrotic foci within the liver were found in model group,mainly distributed around hepatic vein,with a median maximum diameter of 18.50 μm and a median volume of 5 870.11 μm3,but was not observed in control group.Conclusion Phase-contrast CT could be used in three-dimensional visualization of intrahepatic vessels and necrotic foci of in vitro liver in mouse model of ALI.

Objective To investigate the safety and effectiveness of normal saline as a hydrodissection band versus sodium hyaluronate and biopolysaccharide mixture as a modified hydrodissection band in microwave ablation (MWA) for benign thyroid nodules. Methods A total of 196 patients with 245 benign thyroid nodules(maximum diameter ≥20 mm) treated at Shanghai Ruijin Rehabilitation Hospital from August 2018 to February 2022 were enrolled. Patients were divided into control group (n=114): MWA using normal saline as the hydrodissection fluid; modified group (n=131): MWA using sodium hyaluronate and biopolysaccharide mixture as the hydrodissection fluid. A hydrodissection band (about 10 mm wide) was established before MWA. Intraoperative hydrodissection fluid absorption time was recorded. At the 12-month follow-up endpoint, complications were assessed, and changes in nodule volume (volume reduction rate, VRR) were evaluated. Results The complication rate was significantly lower in the modified group (1.9% vs.14.0%, P<0.05). 92.3% of complications in the control group were thermal injury-related, while no thermal injuries occurred in the modified group. Hydrodissection fluid absorption time was significantly prolonged in the modified group [(15.2±1.6) min vs. (11.0±2.3) min, P<0.05].No significant difference was observed in overall treatment efficacy (nodule VVR) between two groups (95.4% vs. 96.5%, P>0.05). Conclusions The sodium hyaluronate and biopolysaccharide mixture demonstrates prolonged retention time and superior thermal insulation as an hydrodissection fluid in MWA. It reduces adhesion risks and complications such as hoarseness, dysphagia, and thermal injury, thereby enhancing procedural safety and postoperative recovery. MWA is an effective treatment for benign thyroid nodules.

In recent years, the application of artificial intelligence technology in rectal cancer radiotherapy has become increasingly significant. By constructing models from patient clinical information, accurate prediction of dose distribution, treatment effect, and toxic side effects of rectal cancer can be achieved. This allows optimizing the radiotherapy plan, ensuring the dose is focused on the tumor target area while reducing the radiation damage to the bladder, rectum, and other surrounding tissues. Thus, it can achieve precision and personalization in radiotherapy. In this review, the construction method of artificial intelligence predictive models was described, and the value of different predictive factors to the model was systematically analyzed, including patient clinical data, radiomics, and dosimetry. Moreover, the application and limitations of artificial intelligence predictive models in radiotherapy were summarized. This information can serve as a reference for the clinical application of artificial intelligence predictive models in rectal cancer radiotherapy.

ObjectiveTo investigate the value of prealbumin-to-total bilirubin （PA/TBil） ratio on admission in predicting 90-day mortality or liver transplantation in patients with HBV-related acute-on-chronic liver failure （HBV-ACLF）， as well as the effect of its combination with Model for End-Stage Liver Disease （MELD） score on the predictive performance for short-term prognosis. MethodsA retrospective analysis was performed for the clinical data of 216 HBV-ACLF patients who were admitted to Department of Infectious Diseases in the First Affiliated Hospital of Soochow University from April 2020 to May 2025， and the patients were followed up for 3 months. According to the outcome， the patients were divided into survival group with 104 patients and death/transplantation group with 112 patients. The Kolmogorov-Smirnov test was used to check whether the continuous data was in accordance with the normal distribution； the two-independent-samples t test was used for comparison of normally distributed continuous data between two groups， while the Mann-Whitney U test was used for comparison of continuous data with skewed distribution between two groups. The chi-square test was used for comparison of categorical data between two groups. Univariate and multivariate binary Logistic regression analyses were used to investigate the influencing factors for prognosis， and the receiver operating characteristic （ROC） curve was used to analyze the performance of each indicator in predicting the prognosis of ACLF. The area under the ROC curve （AUC） was calculated， and the Delong test was used for comparison of AUC. ResultsA total of 216 patients were enrolled in this study， with a 90-day survival rate of 48.15% （104/216）. Compared with the death/transplantation group， the survival group had significantly higher platelet count， lymphocyte count， albumin， and PA/TBil ratio （all P<0.05） and significantly lower age， white blood cell count， neutrophil count， prothrombin time， international normalized ratio， aspartate aminotransferase， total bilirubin， creatinine， and MELD score （all P<0.05）. The multivariate Logistic regression analysis showed that age （odds ratio ［OR］=1.05， 95% confidence interval ［CI］： 1.02 — 1.09， P<0.001）， PA/TBil ratio （OR=0.16， 95%CI： 0.05 — 0.46， P<0.001）， and MELD score （OR=1.09， 95%CI： 1.01 — 1.17， P=0.024） were independent influencing factors for 90-day prognosis in HBV-ACLF patients. PA/TBil ratio and MELD score used alone or in combination had an AUC of 0.760， 0.779， and 0.811， respectively， in predicting the prognosis of HBV-ACLF patients， and PA/TBil ratio combined with MELD score had a better AUC than PA/TBil ratio or MELD score used alone （Z=-2.058 and 2.017， both P<0.05）. ConclusionBoth serum PA/TBil ratio and MELD score can effectively predict the prognosis of patients with HBV-ACLF， and a combination of the two indicators had a better predictive performance than MELD score alone， which provides an important reference for clinical risk stratification management and timely intervention.

A retrospective analysis was conducted on data from five patients comprehensively diagnosed with emphysematous osteomyelitis (EO) based on clinical, imaging, microbiological culture, and surgical findings at Hebei Medical University Third Hospital from December 2020 to May 2024. Among these five cases, there were three males and two females, aged between 11 and 69 years. Three patients had infection risk factors (two with diabetes and one with anemia), while two had no documented risk factors in their medical history. All patients presented with fever, localized pain at the infection site, and elevated inflammatory markers. Site of incidence: EO affected the lumbar spine in three cases, the ilium in one case, and the femur in one case. Pathogenic microorganisms: The causative agents included Klebsiella pneumoniae (two cases), Escherichia coli (one case), Burkholderia cepacia (one case), and a mixed infection of Staphylococcus aureus and Acinetobacter baumannii (one case). Imaging findings: Among the three patients who underwent X-ray examinations, one showed normal results, while two exhibited bone destruction. CT scans of all five cases revealed the characteristic "pumice sign" without periosteal reaction or osteosclerosis. MRI, performed on four patients, demonstrated bone destruction, swelling of surrounding soft tissues, and soft tissue abscess formation. Treatment and outcomes: Four patients underwent surgical debridement combined with perioperative antibiotic therapy. Of these, three recovered well, while one achieved good infection control but suffered severe joint destruction. One patient died after treatment was discontinued. The clinical and laboratory findings of EO resemble those of common acute osteomyelitis; however, EO has distinct imaging characteristics. Timely diagnosis, aggressive surgical debridement, and strong, targeted antibiotic therapy can result in favorable outcomes. Conversely, delayed diagnosis and treatment may lead to severe complications or death.
