Objective:To investigate the improvement effect of the freeze-dried garlic powder on acute myocardial ischemia and its effect on phosphatidylinositol 3 kinase/protein kinase B/nuclear factor erythroid 2-related factor 2 (PI3K/Akt/Nrf2) signaling pathway.Methods:SD rats were randomly divided into sham-operation group, model group, positive drug group, and garlic freeze-dried powder low-, medium-, and high-dosage groups using a random number table method, with 12 rats in each group. The garlic freeze-dried powder low-, medium-, and high-dosage groups were orally administered with 0.58, 1.16, and 2.32 g/kg of garlic freeze-dried powder solution, the positive reference drug group was orally administered with 0.26 g/kg of compound Danshen tablet solution, and the model group and sham-operation group were orally administered with equal volumes of distilled water once a day for 14 consecutive days. Except for the sham-operation group, all other groups were prepared with acute myocardial ischemia models in rats by ligating the left anterior descending coronary artery. Electrocardiogram testing was performed. The incidence of ventricular premature beats, ventricular tachycardia, and ventricular fibrillation in each group was counted. Myocardial infarction was observed through TTC staining, and the myocardial infarction rate was calculated; serum creatine kinase (CK), creatine kinase isoenzyme (CK-MB), LDH, cardiac troponin T (cTnT), total antioxidant capacity (T-AOC), SOD, MDA, IL-1β, TNF-α levels were detected, and Western blot was used to detect myocardial tissue p-PI3K, p-Akt, Nrf2, HO-1 and Keap1 proteins.Results:Compared with the model group, the incidence of premature ventricular contractions, ventricular tachycardia, and ventricular fibrillation in rats in each treatment group was reduced. Compared with the model group, the positive drug group and garlic freeze-dried powder medium- and high-dosage groups showed a decrease in myocardial infarction rate in rats ( P<0.05); compared with the model group, the levels of serum T-AOC and SOD in each treatment group increased ( P<0.05 or P<0.01), while the level of MDA decreased ( P<0.05 or P<0.01); the levels of CK, LDH, cTnT, IL-1β, and TNF-α in the serum of rats in the positive drug group and garlic freeze-dried powder high-dosage group decreased ( P<0.05 or P<0.01), while the expressions of p-PI3K, p-Akt, Nrf2, and HO-1 proteins in myocardial tissue increased ( P<0.05 or P<0.01), and the expression of Keap1 protein decreased ( P<0.05 or P<0.01). Conclusions:Garlic freeze-dried powder can improve acute myocardial ischemia of rats by reducing the release of serum myocardial enzymes and exerting antioxidant and anti-inflammatory effects. The mechanism may be related to regulating PI3K/Akt/Nrf2 signaling pathway.

Background and purpose:Thyroid cancer is the most common malignant endocrine tumor,particularly prevalent among the Asian population.The overall survival for thyroid cancer patients is relatively high,but there are significant survival differences among patients.Based on long-term hospital-based cancer registry database,this study analyzed the 10-year observed overall survival(OS)rate of thyroid cancer cases and the distribution of causes of death,providing real-world evidences to further survival management of thyroid cancer in China.Methods:A total of 55343 thyroid cancer patients who underwent treatment at Fudan University Shanghai Cancer center from 2005 to 2021 were included in this study.Clinical information and the follow-up endpoint data were collected through medical records review,telephone visits and death registry data linkage.The last follow-up date was October 31,2024.Kaplan-Meier method was applied in evaluating the OS rate,and survival data were described by different subgroups as age group,gender,treatment period,tumor staging and pathological characteristics.The standardized mortality ratio(SMR)and absolute excess risk(AER)were calculated using general Shanghai population as the reference,and the mortality risk was described by gender,age at diagnosis and histological subtype.Results:With a median follow-up time of 63.01 months,the overall 1-,3-,5-and 10-year OS rates of thyroid cancer patients were 99.67%(95%CI:99.62%-99.72%),99.11%(95%CI:99.03%-99.19%),98.48%(95%CI:98.36%-98.60%)and 95.81%(95%CI:95.50%-96.11%),respectively.The 10-year OS rates of stage Ⅰ,Ⅱ,Ⅲ and Ⅳ were 97.99%(95%CI:97.70%-98.28%),89.80%(95%CI:87.24%-92.37%),77.84%(95%CI:70.76%-84.92%)and 62.95%(95%CI:55.37%-70.54%),respectively.The differences in OS among patients with different age,gender and histological classification were significant.1256(2.27%)deaths occurred,of which 18.63%,50.88%and 7.32%were attributable to thyroid cancer,other cancers and cardiovascular disease(CVD),respectively.Compared with the general population,patients with different subtypes of thyroid cancer had higher all-cause mortality rates,progressively increasing with papillary,follicular,medullary and anaplastic thyroid carcinoma/poorly differentiated carcinoma.Compared with general population,the death risk was 2.24 times higher in papillary thyroid cancer patients(95%CI:2.06-2.44),9.94 times higher in follicular thyroid cancer patients(95%CI:6.79-14.09),12.16 times higher in medullary thyroid cancer patients(95%CI:8.05-17.69),and the highest risk was observed in patients with anaplastic thyroid carcinoma/poorly differentiated carcinoma[SMR=79.67(95%CI:58.38-106.31),AER=766.01/1 000 person-years].Conclusion:The 10-year long survival data and cause of death for thyroid cancer patients with different histological types were reported in China based on a large single institution hospital-based cancer registry database.Staging and histological characteristics were the most important factors directly affected the survival.Early diagnosis and individualized treatment are crucial for improving prognosis.

Objective:To explore the impact of the two-way referral model on compliance and prognosis in patients with heart failure.Methods:This bidirectional cohort study enrolled chronic heart failure (CHF) patients treated at Qilu Hospital of Shandong University or designated primary hospitals between March 2018 and March 2022. Patients were categorized into two groups based on referral status: two-way referral group (participating in the referral model with≥1 follow-up visit at primary hospitals) and the core hospital group (receiving treatment and follow-up exclusively at Qilu Hospital). Baseline clinical characteristics were collected and compared between groups. Patients underwent followed-up, with primary endpoints including follow-up rate, drug (β-blockers, angiotension converting enzyme inhibitor (ACEI)/angiotensin Ⅱ receptor blockers (ARB)/angiotensin receptor-neprilysin inhibitor (ARNI), sodium-glucose cotransporter 2 inhibitors and mineralocorticoid receptor antagonists) utilization rate and target dose achievement rate. Secondary endpoints encompassed changes from baseline in left ventricular ejection fraction (LVEF), left ventricular end-diastolic diameter (LVEDd), and N-terminal pro-brain natriuretic peptide (NT-proBNP), plus cardiovascular mortality and heart failure rehospitalization. Generalized linear mixed models analyzed longitudinal trends in LVEF, LVEDd, and NT-proBNP levels. Kaplan-Meier curves and Cox regression evaluated LVEF recovery rates, supplemented by subgroup analyses. Multivariate logistic regression was used to identify factors influencing target dose achievement rate for β-blockers and ACEI/ARB/ARNI therapies in CHF patients.Results:A total of 357 patients were enrolled, aged 53 (41, 63) years, including 256 males (71.7%). 157 patients were in the two-way referral group and 200 patients in the core hospital-treated group. Compared with the core hospital-treated group, the two-way referral group had lower baseline LVEF (28 (22, 34)% vs. 31 (23, 36)%, P=0.021) and systolic blood pressure (116 (104, 125) mmHg vs. 121 (109, 134) mmHg (1 mmHg=0.133 kPa), P=0.010). The 12-month follow-up rate of the two-way referral group was higher than the core hospital-treated group (73.8% vs. 56.0%, P=0.004). No significant between-group differences were observed in drug utilization rate of β-blockers, ACEI/ARB/ARNI, or sodium-glucose cotransporter 2 inhibitors during follow-up (all P>0.05), while mineralocorticoid receptor antagonists use showed a declining trend in both groups. Although the core hospital-treated group had higher target dose achievement rates for β-blockers (65.4% vs. 49.3%, P=0.042) and ACEI/ARB/ARNI (79.8% vs. 65.8%, P=0.046) than the two-way referral group, multivariate logistic regression indicated that the two-way referral model was not a negative predictor for these outcomes (all P>0.05). Both groups showed improved NT-proBNP, LVEDd, and LVEF from baseline (all P<0.001) with no significant difference in trends between groups (all P>0.05). There was no significant difference in the composite incidence (7.6% vs. 6.5%, P=0.674) and cumulative incidence (log-rank P=0.684) of cardiovascular death and heart failure rehospitalization at 12 months between two groups. Conclusion:The two-way referral model demonstrates advantages in improving medication adherence, drug utilization rates, and targetdoseachievement rates among CHF patients. This model not only promotes cardiac functional recovery but also reduces risks of cardiovascular mortality and heart failure rehospitalization, achieving comparable therapeutic and management outcomes to those observed in core hospital-treated patients.

Objective:To investigate the clinical efficacy of minimally invasive double anchoring combined with percutaneous kyphoplasty (PKP) for Kümmell disease.Methods:The clinical data of 24 patients with Kümmell disease who were treated with minimally invasive double anchoring combined with PKP in Cangzhou People's Hospital from October 2022 to March 2024 were retrospectively analyzed. Among them, there were 2 T 10 vertebrae, 5 T 11 vertebrae, 7 T 12 vertebrae, 6 L 1 vertebrae, and 4 L 2 vertebrae. There were 6 males and 18 females. The average age was 72.05±4.52 years (range, 66-80 years). The bone mineral density T value was -3.41±0.77 (range, -2.5-4.5). The stages of Li's Kümmell disease included 13 cases of stage II and 11 cases of stage III. The operation time, intraoperative blood loss, and volume of bone cement injected were recorded. The vertebral index, vertebral angle and Cobb angle of diseased segment were measured before and after operation. The visual analogue scale (VAS) was used to assess the degree of pain, the Oswestry disability index (ODI) and the Japanese Orthopaedic Association (JOA) low back pain scale were used to assess spinal function. The Medical Outcome Study short form 36 item health survey (SF-36) was used to assess the general health status of the patients. The postoperative symptom recovery was evaluated by Odom criteria. Results:The mean operative time of the 24 patients was 35.32±6.86 min, the injected volume of bone cement was 4.39±1.72 ml, and the intraoperative blood loss was 16.56±5.21 ml. All patients were followed up for 10 to 14 months, with an average of 11.7 months. Postoperative CT examination showed that the screw positions were satisfactory, and no loosening or displacement of bone cement mass occurred. On the first day after surgery, the vertebral body index, vertebral body angle and Cobb angle of diseased segment were 77.71%±2.75%, 12.40°±1.53° and 25.77°±4.49°, respectively, which represented significant improvements from the preoperative values of 43.09%±5.66%, 22.12°±2.92° and 46.98°±5.68° before surgery ( P<0.05). At the last follow-up, the values were 76.18%±2.32%, 12.41°±2.53°, 26.14°±4.87°, respectively, which were significantly improved compared with those before surgery ( P<0.05), but there was no statistical significance compared with the first day after surgery ( P>0.05). The VAS, ODI and JOA scores on the first day after surgery were 2.11±0.87 points, 22.46±5.49 points and 27.68±2.45 points, respectively, which were significantly improved compared with those before surgery 7.50±0.98 points, 76.25±8.56 points and 14.96±4.91 points ( P<0.05). At the last follow-up, the values were 2.26±0.88, 23.87±3.25 and 26.58±2.77, respectively, which were significantly improved compared with those before surgery ( P<0.05), and there was no statistical significance compared with the first day after surgery ( P>0.05). All 24 patients completed SF-36 scale assessment, and the results showed that there were statistically significant differences in physiological function, physiological role, physical pain, general health status, social function scores and mental health between the patients before surgery and the last follow-up ( P<0.05), while there were no statistically significant differences in vitality and emotional function ( P>0.05). At the last follow-up, the Odom criteria showed excellent results in 18 cases, good in 4 cases, and fair in 2 cases. Conclusions:The application of minimally invasive double anchoring (single nail fixation) combined with PKP in the treatment of Kümmell disease can effectively prevent the loosening and displacement of bone cement masses, and the fixation effect is satisfactory, which can restore the height of the injured vertebrum, reduce kyphosis and improve spinal function. The clinical symptoms of the patients were significantly improved, and the quality of life was enhanced.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

Objective:To investigate the association between blood selenium levels and sex hormones in Chinese men aged 18-79 years.Methods:Data were derived from the China National Human Biomonitoring survey conducted in 2017-2018, with a final sample size of 5 414 men. General demographic characteristics, behavioral habits, and dietary frequency were collected through questionnaires and physical examinations. Fasting blood samples were collected to measure blood lead, serum testosterone, and estradiol levels. Complex sampling linear regression models were used to analyze the associations between blood selenium levels and testosterone, estradiol, and the testosterone/estradiol ratio, adjusting for confounding factors including age, education level, marital status, smoking status, alcohol consumption, seafood intake, soy product intake, protein supplement intake, BMI, and diabetes status.Results:The mean age of the 5 414 participants was (46.85±27.91) years; 4 774 (91.65%) were of Han ethnicity and 4 505 (86.68%) were married. The median ( Q1, Q3) blood selenium concentration in men was 97.80 (80.64, 116.99) μg/L. After adjusting for confounding factors, the complex sampling linear regression model revealed negative associations between blood selenium levels and both testosterone levels and the testosterone/estradiol ratio, with a significant linear trend ( Ptrend<0.05). Compared with the Q1 group, the β (95% CI) values for testosterone in the Q2, Q3, and Q4 groups were -0.02 (-0.06 to 0.02), -0.03 (-0.08 to 0.01), and -0.06 (-0.09 to -0.02), respectively. Similarly, the β (95% CI) values for the testosterone/estradiol ratio in the Q2, Q3, and Q4 groups were -0.01 (-0.03 to 0.02), -0.01 (-0.04 to 0.04), and -0.03 (-0.06 to -0.01), respectively. Subgroup analysis indicated stronger associations between blood selenium levels and testosterone/estradiol levels in non-smoking and obese men (BMI≥28 kg/m2). Conclusion:Blood selenium levels are negatively associated with testosterone levels and the testosterone/estradiol ratio in Chinese adult males.

ObjectiveTo investigate the features of liver histopathological damage in patients with indeterminate phase of chronic HBV infection， as well as the timing for initiating antiviral therapy in such patients. MethodsA retrospective screening was performed for the patients with chronic HBV infection who were hospitalized in The Fifth Medical Center of Chinese PLA General Hospital and underwent liver biopsy from March 2018 to April 2022， among whom the patients who met the criteria for indeterminate phase defined in Chinese guidelines for chronic hepatitis B prevention and treatment （2022 edition） were enrolled， and their clinical data were collected. Liver histopathological stage was determined using the Scheuer scoring system， with stages 0 — 4 for inflammation grade （G） and stages 0 — 4 for fibrosis degree （S）， and the patients were divided into groups based on the presence of significant necroinflammation （≥G2） and significant liver fibrosis （≥S2）. The independent samples t-test was used for comparison of normally distributed continuous data between two groups， and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups； the chi-square test or the Fisher’s exact test was used for comparison of categorical data between two groups. A Spearman’s rank correlation analysis was used to investigate the correlation between liver histopathology and clinical factors， and the Logistic regression model was used to identify the independent influencing factors for significant necroinflammation and liver fibrosis. ResultsA total of 271 patients with indeterminate phase of chronic HBV infection were enrolled， among whom 61 （22.5%） had significant necroinflammation （≥G2） and 124 （45.8%） had significant liver fibrosis （≥S2）. The Logistic regression analysis showed that alanine aminotransferase ≥30 U/L （for male patients） or ≥19 U/L （for female patients） （odds ratio ［OR］=2.69， 95% confidence interval ［CI］： 1.39 — 5.21， P=0.003）， HBV DNA ≥2 000 IU/mL （OR=2.75， 95%CI： 1.38 — 5.48， P=0.004）， and liver stiffness measurement （LSM） ≥6.0 kPa （OR=4.57， 95%CI： 2.17 — 9.62， P<0.001） were independent risk factors for significant inflammation. HBV DNA ≥2 000 IU/mL （OR=1.82， 95%CI： 1.01 — 3.32， P=0.049） and LSM ≥6.0 kPa （OR=2.06， 95%CI： 1.23 — 3.43， P=0.006） were independent influencing factors for significant liver fibrosis. ConclusionAmong the patients with indeterminate phase of chronic HBV infection， a substantial proportion of patients have significant liver histopathological damage. Antiviral therapy should be initiated in a timely manner for patients with high-risk factors.

The transcription factor HOXB13 plays crucial roles in cancer development. HOXB13 is abnormally expressed in most cancers, which makes it a valuable therapeutic target for cancer therapy. The level of HOXB13 differs significantly between healthy and cancer tissues, which indicates that the level of HOXB13 is closely related to carcinogenesis. The regulatory network mediated by HOXB13 in cancer proliferation, metastasis, and invasion has been systematically investigated. Moreover, HOXB13 variants play distinct roles in different cancers and populations. By understanding the molecular mechanisms and mutation features of HOXB13, we provide a comprehensive overview of carcinogenesis networks dependent on HOXB13. Finally, we discuss advancements in anticancer therapy targeting HOXB13 and the roles of HOXB13 in drug resistance to molecular-targeted therapies, which serves as a foundation for developing HOXB13-targeted drugs for clinical diagnosis and cancer therapies.
