Objective To investigate the impact of anti-reflux modified duodenal exclusion surgery on glucose metabolism in rats with type 2 diabetes mellitus (T2DM), and to elucidate the role of the duodenum in maintaining glucose homeostasis. MethodsForty male Sprague-Dawley rats aged 5 weeks were fed a high-fat diet and induced with T2DM using low-dose streptozotocin. Thirty-six rats that met the T2DM model criteria were randomly divided into three groups: the simple duodenal exclusion surgery group (DE group), the anti-reflux modified duodenal exclusion group (MDE group), and the sham operation group (SO group), with 12 rats in each group. Gastroenterography was performed 4 weeks after surgery, and the body weight, fasting blood glucose levels, and serum glucagon-like peptide-1 (GLP-1) concentrations were measured before surgery and at 1, 2, 4, and 8 weeks post-surgery. Eight weeks post-surgery, the rats were euthanized, and a 1 cm segment of the biliopancreatic loop was collected from each group for pathological sectioning and HE staining to observe the intestinal mucosal villus length under an optical microscope. Results Gastroenterography showed that there was significant reflux of the contrast agent into the duodenal lumen in the DE group, while no reflux was observed in the MDE group. At one week post-surgery, the body weights of rats in all three groups significantly decreased compared to before surgery (P<0.05), and then the body weights of all groups increased over time, with no significant differences between the groups (P>0.05). Compared with the SO group, the fasting blood glucose levels in the MDE and DE groups significantly decreased at all time points post-surgery (P<0.05), while GLP-1 concentrations significantly increased (P<0.05). The fasting blood glucose levels in the MDE group were lower than those in the DE group at all time points post-surgery (P<0.05), but there were no significant differences in serum GLP-1 concentrations between the MDE and DE groups (P>0.05). Regarding intestinal mucosal morphology, the villus lengths of the biliopancreatic loops in the MDE group were significantly shorter than those in the DE and SO groups (P<0.05). Conclusion Anti-reflux modified duodenal exclusion surgery effectively improves glucose metabolism in T2DM rats by preventing the reflux of chyme into the diverted duodenum, thereby enhancing its hypoglycemic effect.

Journal of Zhejiang University. Science. B 2023;24(7):549-553
"Let food be thy medicine and medicine be thy food"-the ancient adage proposed by Greek philosopher Hippocrates of Kos thousands of years ago already acknowledged the importance of the beneficial and health-promoting effects of food nutrients on the body (Mafra et al., 2021). Recent epidemiological and large-scale community studies have also reported that unhealthy diets or eating habits may contribute heavily to the burden of chronic, non-communicable diseases, such as obesity, type 2 diabetes mellitus (T2DM), hypertension, cardiovascular disease (CVD), cancer, neurodegenerative diseases, arthritis, chronic kidney disease (CKD), and chronic obstructive pulmonary disease (COPD) (Jayedi et al., 2020; Gao et al., 2022). Emerging evidence highlights that a diet rich in fruits and vegetables can prevent various chronic diseases (Chen et al., 2022). Food bioactive compounds including vitamins, phytochemicals, and dietary fibers are responsible for these nutraceutical benefits (Boeing et al., 2012). Recently, phytochemicals such as polyphenols, phytosterols, and carotenoids have gained increasing attention due to their potential health benefits to alleviate chronic diseases (van Breda and de Kok, 2018). Understanding the role of phytochemicals in health promotion and preventing chronic diseases can inform dietary recommendations and the development of functional foods. Therefore, it is crucial to investigate the health benefits of phytochemicals derived from commonly consumed foods for the prevention and management of chronic diseases.

Objective:To investigate the efficacy and safety of retroperitoneal soft tissue sarcoma resection combined with nephrectomy.Methods:The clinical data of 27 cases undergoing retroperitoneal soft tissue sarcoma resection combined with nephrectomy at the Gastrointestinal Tumor Center , Guangdong Provincial Hospital , Traditional Chinese Medicine from Jun 2017 to Aug 2022 were retrospectively analyzed for the indication of nephrectomy, postoperative progression of renal insufficiency and survival rate.Results:Twenty-six cases (96%) achieved R 0/R 1 resection and 1 case nderwent R 2 resection. Six cases underwent combined unilateral nephrectomy and 21 patients underwent combined multi-organ resection with a median number of resections of 4 (2,5). Postoperative pathology suggested that the combined resected kidney was positive for tumor infiltration in 17 cases. Five cases had Clavien-Dindo grade 3 or higher complications and no deaths occurred within 30 days after surgery. At the 90th day after surgery, 19 cases (70%) had decreased renal function ( Z=2.88, P=0.04), with a median decrease of -3.96 (-30.36, 0.31)ml·(min·1.73 m 2) -1, including 8 cases of preoperative Chronic Kidney Disease(CKD)1 stage progression (6 cases of CKD 2 stage, 2 cases of CKD 3 stage); 2 cases of CKD 2 stage progressed to CKD 3 stage; 1 case of preoperative CKD 3 stage progressed to CKD 4 stage. During the follow-up period of 3-38 months, no patient progressed to CKD 5 stage and no patient required dialysis treatment. Conclusion:Retroperitoneal soft tissue sarcoma resection combined with nephrectomy is safe and feasible while improving tumor radicality.

Objective:To simulate the effects of different thyroid-neck phantoms and monitoring positions on the detection efficiency of portable γ spectrometer, and to provide guidance for more accurate on-site measurement of 131I activity in the human thyroid. Methods:Based on the models of 4 typical thyroid-neck phantoms and a 3-inch NaI (TI) γ spectrometer used for the measurement of 131I in the thyroid and combined with the possible field monitoring scenarios, the Monte Carlo method was used to simulate and calculate the detection efficiency of the spectrometer under different conditions of monitoring distance, thyroid depth and thyroid volume. Results:The detection efficiency decreased significantly with the increase in the distance between the detector and the neck surface. The efficiency close to the neck surface was about 15 times that at 15 cm away from the neck surface. The detection efficiency decreased significantly with the increase in thyroid depth. When it was measured at the surface of the neck, the detection efficiency of thyroid at depth of 2 mm was about 3.6 times that of 30 mm. The detection efficiency decreases with the increase in thyroid volume. When it was measured at the neck surface, the detection efficiency of thyroid with 1 ml volume was 1.71 times that with 30 ml. The detection efficiency decreased with the center-point offset of the detector, especially at the neck surface, an offset of 2 cm would reduce the detection efficiency by about 15%.Conclusions:Not only the measurement distance used in calibration, but also the information of the depth and volume of thyroid in the neck-thyroid phantom, is important to know in advance for an accurate measurement of 131I activity in thyroid by using a portable gamma spectrometer.

Objective:To investigate the feasibility of reducing the radiation dose on coronary artery calcium score (CS) of virtual non-contrast (VNC) scanning in dual-layer spectral coronary CT angiography(CCTA).Methods:One hundred and twenty-two patients were examined on a dual-layer spectral detector CT scanner from March 2019 to August 2020. Volume CT dose index (CTDI vol), dose length product (DLP), effective dose ( E) were all evaluated for each patient. CS was calculated from both true non-contrast (TNC) and VNC images for left anterior descending (LAD), left circumflex (LCx), right coronary artery (RCA), and the total coronary artery (Total) by two radiologists independently. Pearson′s correlation coefficient was calculated for measuring the association between variables. The correction coefficients of each branch (λ LAD, λ LCx, and λ RCA) and the average correction coefficient (λ AVG) of the total coronary artery were obtained. The calibrated calcium score (CCS_VNC) was equal to λ multiplied by CS_VNC. The CS_TNC and CCS_VNC were compared using repeated oneway analysis of variance test. Correlation analyses for CS_TNC and CCS_VNC and agreement evaluation with Bland-Altman-Plots were performed. Results:The average effective doses in TNC, CCTA and total group were 0.69, 6.47 and 7.16 mSv, respectively. The effective dose was reduced by 10.6% and the scan time was reduced by 39% while using VNC images. There were significant differences among the CS_TNC and CS_VNC of LAD, LCx, RCA and Total ( t=6.75, 5.33, 4.99, 6.60, P< 0.05). Excellent correlations were observed between CS_VNC and CS_TNC ( R2 values were 0.929, 0.896, 0.958, and 0.918; λ values were 2.18, 1.18, 2.15, and 2.07, respectively). There were no significant statistically difference among the CS_TNC, CCS_VNC AVG, and CCS_VNC LAD/RCA of the LAD and RCA (all P> 0.05). The difference was statistically significant among the CS_TNC, CCS_VNC AVG, and CCS_VNC LCx of the LCx ( F=10.94, P<0.05). The paired comparison were performed in groups and the differences were statistically significant between the CS_TNC versus CCS_VNC AVGand CCS_VNC AVG versus CCS_VNC LCx ( t=3.31, 3.43, all P<0.05). There was no significant statistically difference between the CCS_VNC LCx and CCS_VNC AVG( P>0.05). Conclusions:It was feasible to accurately evaluate the CS_VNC from spectral data in comparison to TNC imaging, and to reduce the patient radiation dose and acquisition time.

Objective To evaluate the effectiveness and safety of a central venous catheter for thoracic drainage after video-assisted thoracoscopic lobectomy compared with a conventional chest tube. Methods This study collected 200 patients with lung cancer who underwent thoracoscopic lobectomy and systematic hilar and mediastinal lymph node dissection between January 2018 and September 2019 in our hospital. The patients were randomly divided into two groups, including a group A (left with 28F chest tubes postoperatively) and a group B (left with 12G central venous catheters postoperatively). Patients in both groups were left with 2 chest tubes after upper lobectomy and 1 chest tube after middle or lower lobectomy. Duration and total volume of drainage, length of hospital stay, maximum visual analogue scale score and so forth were compared between the two groups. Results Finally, 151 patients were included for analysis. There were 73 patients in the group A, including 26 males and 47 females, with an average age of 55.38±9.95 years, and 78 patients in the group B, including 37 males and 41 females, with an average age of 59.86±10.18 years. No statistical difference was found between the two groups in drainage volume on postoperative day 2, and proportion of prolonged air leaks, hemothorax, chylothorax or drain reinsertion (all P>0.05). There was a statistical difference in drainage volume on postoperative day 1 [200.0 (120.0, 280.0) mL vs. 57.5 (10.0, 157.5) mL, P=0.000], postoperative day 3 [155.0 (100.0, 210.0) mL vs. 150.0 (80.0, 215.0) mL, P=0.023], total volume of drainage [890.0 (597.5, 1 530.0) mL vs. 512.5 (302.5, 786.3) mL, P=0.000], maximum pain score (2.29±0.72 points vs. 2.09±0.51 points, P=0.013) and length of hospital stay [7 (7, 9) d vs. 5 (4, 7) d, P=0.000]. Conclusion Compared with conventional chest tubes, central venous catheters for chest drainage in patients with lung cancer after thoracoscopic lobectomy shortens the length of hospital stay and reduces postoperative pain.

10.Pituitary metastasis of thyroid carcinoma: A case report
Chinese Journal of Endocrinology and Metabolism 2021;37(5):481-484
Pituitary metastasis is a rare tumor complication, and papillary thyroid carcinoma is a tumor with low hematogenous dissemination tendency. Here we report a rare case with pituitary metastasis from papillary thyroid cancer. This patient was 43 years old and was admitted to our hospital because of " blurred vision in the right eye" . She had partial thyroidectomy because of thyroid nodule 8 years ago, and was diagnosed as papillary thyroid carcinoma, but without any further treatment onwards. After admission, MRI revealed a pituitary mass protruding through the sella turcica into the right sphenoid sinus. Neuro-endoscopic transsphenoidal resection was performed to relieve visual impairment. Pathological result was papillary thyroid carcinoma pituitary metastasis. She underwent thyroidectomy 2 months later. Because tumor of the left lobe invaded the esophagus, it was resected palliatively, and adjuvant therapy with radioactive iodine was performed subsequently. This case suggests that long-term management of papillary thyroid carcinoma should be strengthened to reduce the risk of recurrence and metastasis, additionally radioiodine therapy is an important complementary treatment.
