Objective To summarize experience in treating patients with native value endocarditis ( NVE) , and discuss the effect of timing of surgery on the infection control , cardiac function recovery and long-term mortality among patients . Methods Eighty NVE cases with antibiotic treatment were recruited between January 2006 and May 2013 .According to the timing of surgery, the subjects were divided into the early surgery group (38 cases) and the late surgery group (42 ca-ses) .The infection-related markers and cardiac function indexes before and after surgery , and 1-year, 3-year and 5-year mortality after surgery were analyzed .Results The infection control and recovery of cardiac function in the early surgery group were better than in the late surgery group (P<0.05).The difference in 3-year and 5-year mortalities between the two groups was significant .Conclusions For NVE patients with routine antibiotics treatment , the surgical effect and long-term survival rate are much better in the early surgery group than in the late surgery group .

Objective To evaluate the value of technetium-99m methoxy isobutyl isonitrile(99Tcm-MIBI) tomography and integrated CT scan in preoperative localization diagnosis of primary hyperparathyroidism (PHPT). Methods 31 patients with PHPT were selected .15 minutes and 90 minutes ( delayed images ) after intravenous administration of 99 Tcm-MIBI 370 MBq, static anterior planar images of the neck and chest were obtained .99 Tcm-MIBI tomography and integrated CT scan were acquired after the delayed images .All patients received neck ultra-sound scan before surgery .The imaging findings were compared to the pathological results .Results The detec-tion rate of hyperparathyroidism lesions of 99 Tcm-MIBI dual-phase imaging and 99 Tcm-MIBI tomography and regis-tration with integrated CT scan was 87.1%and 93.5%respectively, without statistical significance (P>0.05). However , they were both higher than ultrasound scan which had a detection rate of 64.5%.The differences had statistical significance (χ2 =4.039 and 7.884 respectively , P<0.05 ) .The detection rate of parathyroid hyper-plasia of 99 Tcm-MIBI tomography and registration with integrated CT was both 80.0%, higher than that of the ul-trasound test(40.0%)and 99Tcm-MIBI dual-phase imaging(40.0%).The fusion imaging with integrated CT scan provided detailed anatomy data and more information for surgical doctors .Conclusions 99 Tcm-MIBI tomography and registration with integrated CT scan can improve the detection rate of PHPT compared with 99 Tcm-MIBI dual-phase imaging , provide detailed anatomy data , and has high clinical value in preoperative localization diagnosis of PHPT.

Objective:To study the efficacy and safety of anlotinib in the treatment of advanced radioactive iodine-refractory differentiated thyroid cancer (RAIR-DTC) and the effect of anlotinib on iodine uptake of lesions.Methods:A retrospective analysis was performed on 23 patients (10 males and 13 females, age (59.1±8.7) years) with advanced RAIR-DTC who were treated with anlotinib in Liaocheng Hospital Affiliated to Shandong First Medical University between January 2019 and February 2023 and met the enrollment criteria. Thyroid function, serum thyroglobulin (Tg) and Tg antibody (TgAb) were determined every 6 weeks during the treatment with anlotinib, and maximum diameter of target lesion (TL) was monitored by CT every 12 weeks, in order to evaluate the therapeutic efficacy, and treatment-related adverse reactions were observed. Diagnostic 131I whole body scan (Dx-WBS) was performed in some patients to evaluate the changes in iodine uptake of lesions after anlotinib treatment. In this study, the posttreatment changes of patients within 24 weeks during the treatment were analyzed. The maximum diameter of TL and Tg at different time points were compared by Friedman test, and were further compared in pairs with P values corrected by Bonferroni method. Results:After 24 weeks of treatment with anlotinib, 8 of 23 patients achieved partial response, 15 had stable disease, and no patients achieved complete response. Serum Tg levels at 6, 12, 18, 24 weeks after anlotinib treatment were 189.5(85.0, 483.3), 127.7(52.4, 319.8), 82.0(40.2, 213.5) and 80.1(39.9, 205.0) μg/L, all of which were lower than the baseline level of Tg (384.5(210.9, 1 605.0) μg/L; χ2 values: 4.23-7.86, all P<0.001). Tg level at 18 weeks after treatment was statistically different from that at 12 weeks after treatment ( χ2 =3.06, P<0.001), but was not statistically different from that at 24 weeks after treatment ( χ2 =12.57, P=0.059). The maximum TL diameters of lung and cervical lymph nodes were significantly reduced at week 12 and 24 of anlotinib treatment compared with baseline ( χ2 values: 14.76-31.12, all P<0.001), while there was no significant difference in TL maximum diameter at 12 and 24 weeks of treatment ( χ2 values: 5.65, 9.02, P values: 0.314, 0.070). Common adverse reactions included hypertension, hand-foot syndrome, hyperacylglyceremia and proteinuria. No adverse reactions above grade 4 or death related to adverse reactions occurred. Dx-WBS evaluation was performed in 7 patients after anlotinib treatment, and no change in iodine uptake was found. Conclusions:Anlotinib has a clear effect on advanced RAIR-DTC with less adverse reactions. The efficacy of anlotinib reaches the strongest at around 12-18 weeks and becomes stable at 24 weeks. No effect of anlotinib on inducing redifferentiation of RAIR-DTC cells and enhancing iodine uptake is found.

Objectives:To understand the association between obesity and the risk for colorectal advanced adenoma.Methods:Community residents aged 45 to 74 who had participated in the Shanghai community-based colorectal cancer (CRC) screening project in 2008 were included in our study. Anthropometries information including body weight, height and risk factors for colorectal advanced adenoma were collected. Results on colonoscopic diagnosis and personal health records were used for supplementary outcome information retrieval. Multivariate Cox proportional hazard regression models were used to evaluate the hazard ratio ( HR) and 95 %CI of obesity on the risk for colorectal advanced adenoma. Results:20 811 residents were followed up for 122 739.36 person-years, with a median follow-up time of 5.87 years. A total of 657 cases of advanced adenomas were identified. After adjusting for potential confounding risk factors such as age, sex, family history of CRC, level of education, marriage, cigarette smoking, alcohol drinking, foods intake including fat, fried or pickled, vegetables and fruits etc., the HR was 1.25 (95 %CI: 1.04-1.51) for obese people when compared with the normal weight persons. Further stratified analysis by age, gender and family history of CRC, results showed that obese people had a much higher risk of colorectal advanced adenoma than those with normal weight (male: HR=1.57, 95 %CI: 1.20-2.04; more than 60- year-old: HR=1.63, 95 %CI: 1.23-2.16). Conclusion:Data from this large scale population-based study revealed that obesity might be an independent risk factor for colorectal advanced adenoma and the risk increases along with the increase of BMI in China.

Objective:
To investigate the relationship between V-raf murine sarcoma viral oncogene homologue B1 (BRAF)V600E mutation and metastasis after thyroidectomy in papillary thyroid carcinoma (PTC) with different recurrence risk stratification.
Methods:
From March 2014 to September 2017, 134 PTC patients (45 males, 89 females; age: 16-72 years) who underwent 131I treatment in the Department of Nuclear Medicine of Liaocheng People′s Hospital and had undergone BRAFV600E mutation detection were retrospectively analyzed. The recurrence risk during surgery was divided into 3 levels: low-, medium- and high-risk. Each recurrence risk group was divided into 3 subgroups according to the postoperative follow-up results: non-metastasis group, cervical lymph node metastasis group and pulmonary metastasis group. BRAFV600E mutation rates in different groups were compared (
