A total of 121 patients with metabolic syndrome (MS) and 120 normal subjects were recruited for exploring the association of serum adipokines with MS. The levels of resistin and adipocyte fatty acid-binding protein (A-FABP) increased, while adiponectin decreased gradually ( all P<0.05 ) in normal control group, MS without abdominal obesity group, and MS with abdominal obesity group. In MS group, resistin was positively correlated with body mass index ( BMI), waist circumference, systolic blood pressure, fasting plasma glucose, and A-FABP ( P<0.05 or P<0.01 ). Adiponectin was positively correlated with high-density lipoprotein-cholesterol and negatively correlated with BMI, waist circumference, fasting insulin, triglyceride, and homeostasis assessment of insulin resistant index.

Serum adipocyte fatty acid-binding protein (A-FABP) was raised in metabolic syndrome (MS)patients (n= 121) as compared with age-matched healthy subjects [n = 120, (14.7±4.8 vs 6.8 ±3. 0) μg/L,P<0.001]. It reached higher level in MS subjects with visceral obesity [(15.7±4.2 vs 12.6±5.1) μg/L, P<0.001]. Serum A-FABP concentration was positively correlated with body mass index, waist circumference, waist-tohip ratio, fasting insulin, homeostasis assessment for insulin resistance (HOMA-IR), fasting glucose, triglycerides,total cholesterol,and mean arterial blood pressure, whereas negatively correlated with HDL-C (r =-0. 448, P< 0.001).

OBJECTIVE: To compare the clinical effects and complications of two hybrid decompression techniques in treating multilevel (>=3) cervical spondylotic myelopathy(MCSM). METHODS: The clinical data of 124 patients with multilevel (>=3) cervical spondylotic myelopathy treated by surgery and follow-up from January 2008 to December 2016 were retrospectively analyzed. According to the different operative methods, the patients were divided into group A and group B. Anterior cervical discectomy and fusion (ACDF) combined with anterior cervical corpectomy and fusion with preserved posterior vertebral wall (PWCF) were performed in group A; ACDF combined with anterior cervical corpectomy and fusion(ACCF) were performed in group B. There were 44 males and 16 females in group A with an average age of (60.43±7.52) years old, 46 males and 18 females in group B with an average age of (61.61±6.39) years old. No significant differences were found in gender, age between two groups. The operative time, intraoperative blood loss, hospital stay, rate of complications, postoperative Japanese Orthopaedic Association (JOA) score and improvement of cervical curvature were compared between two groups. RESULTS: All the operations were successful. The follow-up time was 13 to 28(23.0±12.1) months in group A and 12 to 30(24.0±11.5) months in group B. The operative time, intraoperative blood loss, hospital stay in group B were higher than those in group A(<0.05). A total of 37 patients occurred complications, including 14 cases in group A and 23 cases in group B. The incidence of complications was 23.33%(14/60) in group A and 35.94%(23/64) in group B. The incidence of complications in group B was significantly higher than that in group A(<0.05). Postoperative JOA scores were significantly improved (<0.01), there was no significant difference between two groups (>0.05). The physiological curvature of cervical vertebra was improved significantly after operation, and there was no significant difference between two groups(>0.05). CONCLUSIONS Both surgical methods can obtain satisfactory clinical efficacy for multilevel(>=3) cervical spondylotic myelopathy, but compare with group B (ACDF combined with ACCF), group A (ACDF combined with PWCF) has shorter operation time, less trauma, less bleeding, and lower incidence of complications. ACDF combined with PWCF can be preferentially selected for the patients who corresponding to the indications.

Objective:To investigate the diagnostic and prognostic value of 68Ga-fibroblast activation protein inhibitor (FAPI) PET for hepatobiliary malignancies. Methods:From July 2020 to February 2023, 33 patients (23 males, 10 females; age (55.4±13.5) years) with suspected or confirmed liver or biliary tract malignancies who underwent 68Ga-FAPI PET in Union Hospital, Tongji Medical College, Huazhong University of Science and Technology were retrospectively analyzed. PET images were evaluated by 3 experienced nuclear medicine physicians, and the results of biopsy or postoperative pathology, clinical and imaging follow-up were used as the gold standard. One-way analysis of variance and least significant difference t test were used to compare the differences among groups. Survival analysis was performed using Kaplan-Meier curves and the log-rank test. Results:Of 33 patients, 14 performed PET for initial diagnosis and staging, and 19 for restaging. There were 14 patients with hepatocellular carcinoma (HCC), 13 patients with cholangiocarcinoma (CCA), and 6 patients with gallbladder carcinoma (GBC). The primary tumor of HCC, CCA and GBC all showed significant 68Ga-FAPI uptake, with no statistically significant difference in SUV max among groups ( F=1.58, P=0.250). The sensitivities of 68Ga-FAPI PET for initial diagnosis and restaging of hepatobiliary malignancies were 14/14 and 15/15, respectively. Compared with conventional imaging, 68Ga-FAPI PET changed the diagnosis and staging in 29.2%(7/24) patients. The treatment strategy was changed in 30.3%(10/33) patients with malignant tumors due to 68Ga-FAPI PET findings. Follow-up showed 22 cases survived and 11 cases died, with the overall survival of 355.56(80.00, 516.97) d, and 1- and 2-year survival rates were 68.2% and 57.9%, respectively. Semi-quantitative 68Ga-FAPI PET parameters such as SUV max, target-liver ratio (TLR), and target-blood ratio (TBR) had no significant prognostic value, but the prognosis of the group without distant metastases diagnosed by 68Ga-FAPI PET was significantly better than that of the group with distant metastasis ( P=0.032). Conclusion:68Ga-FAPI PET has high sensitivity for the diagnosis of hepatobiliary malignancies, which can help guide treatment decisions and prognosis evaluation.

Objective To provide a reliable and stable animal model for investigating the molecular pathogenesis of radiation-induced liver disease (RILD). Methods Ninety C57BL/6J mice were divided into control, 20 Gy, 25 Gy, 30 Gy and 35 Gy radiation groups. The mice were executed at 4 weeks after radiation and the levels of alanine aminotransferase, aspartate aminotransferase, and alkaline phosphatase in the liver serum were measured. HE staining was performed on the pathological liver tissues. Masson staining was performed at 36 weeks after radiation. Results Compared with the control group, the fatality rate was higher in the 30 and 35 Gy radiation groups, and the body weight significantly decreased in the 20 and 25 Gy radiation groups. Compared with the control group, alanine aminotransferase significantly increased in mice exposed to 20 Gy, while aspartate aminotransferase and alanine aminotransferase increased in mice exposed to 25 Gy. No significant changes were observed in the livers of the mice in the 20 and 25 Gy radiation groups, but pathological examination showed liver damage induced by both 20 and 25 Gy radiation. Conclusion A stable and reliable mouse model of RILD was constructed for treatment with linear accelerator. The mouse model of RILD constructed for stereotactic body radiation therapy using linear accelerator has significant research implications for the exploration of RILD.

Xiaojin pills, the first choice for clinical treatment of breast hyperplasia, were selected to explore the suitability of a bioactivity assay with chemical fingerprinting for the development of an overall quality evaluation assay. The liposoluble and water-soluble fraction fingerprints of Xiaojin pills were established. The ability to inhibit platelet aggregation and the rate of inhibition of cyclooxygenase-2 (COX-2) for 16 batches of Xiaojin pills from several manufacturers was analyzed; the chemical fingerprints of these samples were correlated with the bioactivity and chemical analysis. The animal protocol was approved by the Committee on the Ethics of Animal Experiments of Affiliated Hospital of Chengdu University of Traditional Chinese Medicine Approval, ID: 2018BL-002. Results showed that the antiplatelet aggregation activity of 16 batches was 0.712-1.278 U∙mg^-1, with a relative standard deviation (RSD) of 15.4%. COX-2 inhibition was 52.07%-68.95% and the RSD was 8.91%. The results showed that there was little difference in the biological effects of these samples. However, the chemical fingerprint consistency of these 16 batches of Xiaojin pills was poor, and the similarity of nearly half of the samples was less than 0.9. The total peak area of Xiaojin pills was 32.74%-165.37% across samples, showing very poor chemical consistency. In order to explore the reasons for the poor chemical consistency despite good consistency in the biological assays, the fingerprint chromatogram was analyzed by multivariate statistical analysis. The main chromatographic peaks were identified. The results showed that the similarity of Xiaojin pills was mainly determined by the prominent chromatographic peaks 17, 18, 20, 23 and 27 in the liposoluble fingerprints, which were identified from Liquidambaris resina and Angelica sinensis Radix. However, Liquidambaris resina and Angelicae sinensis Radix had almost no anti-platelet aggregation activity or COX-2 inhibitory effect at the normal prescription ratio. As a result, the ability to utilize chemical fingerprints to evaluate the quality consistency of Xiaojin pills is limited. The selection of biological evaluation methods that reflect clinical efficacy could make up for the shortcomings of chemical evaluation methods for quality assessment, and provide new ideas and methods for the overall quality evaluation of complex Chinese patent medicines.
