Background Tributyl phosphate (TBP) is widely used as an organophosphate flame retardant. However, there are limited studies on the toxicity of TBP to aquatic organisms at low levels of exposure. Objective To investigate the effects of TBP on early development of zebrafish (Danio rerio). Methods Zebrafish embryos were randomly divided into four groups at 2 h post-fertilisation (2 hpf), namely, the 0.01% dimethyl sulfoxide (DMSO) control group and TBP exposure groups (0.02, 0.2 and 2 μg·L⁻¹). The exposure time was from 2 hpf to 120 hpf and the hatching rate, malformation rate, heart rate and body length of zebrafish embryos at 72 hpf, the frequency of tail curling at 24-29 hpf, the locomotor ability at 96 hpf and the survival rate at 120 hpf were evaluated, respectively. The whole-body triiodothyronine (T₃) and tetraiodothyronine (T₄) levels of juvenile fish were measured by enzyme immunoassay at the end of the infection, and the expression levels of hypothalamic-pituitary-thyroid axis (HPT) and neurodevelopmental-related genes were detected by quantitative real-time PCR (q-PCR). Results The heart rates of zebrafish embryos were significantly decreased in all TBP-treated groups (P<0.001), the survival rates of the 0.02 and 2 μg·L⁻¹ TBP groups were significantly decreased (P<0.05), and the malformation rate of the 2 μg·L⁻¹ treated group was significantly increased (P<0.05), which was mainly manifested by pericardial oedema. The frequency of tail curling of zebrafish embryos in all groups reached the highest at 25 hpf, which was significantly lower (P<0.001) in all exposure groups than in the control group (P<0.001). In the locomotor behaviour experiments, the swimming speed of zebrafish larvae in the dark cycle was significantly decreased in the 0.02 and 0.2 μg·L⁻¹ TBP groups (P<0.05), and similar results were found for the light cycle in the 0.2 and 2 μg·L⁻¹ TBP groups (P<0.05). Compared with the control group, the T₃ level of zebrafish juveniles in the 0.2 μg·L⁻¹ TBP group increased significantly (P<0.05). The q-PCR results showed that the expression levels of HTP axis-related genes [thyroid hormone receptors (trα, \begin{document}$tr\beta $\end{document}), thyroglobulin (tg), and sodium/iodide co-transporter (nis)] were significantly down-regulated in the exposure groups, the expression level of transthyretin (ttr) was significantly up-regulated in the 0.02 μg·L⁻¹ TBP group, and the iodothyronine deiodinase 2 (dio2) expression level was significantly down-regulated in the 0.02 μg·L⁻¹ TBP group (P<0.05); the neurodevelopment-related gene acetylcholinesterase (ache) was significantly down-regulated in the exposure groups, and the expression levels of myelin basic protein (mbp) and Elav like neuron-specific RNA binding protein 3 (elavl3) were significantly down-regulated in the 0.02 μg·L⁻¹ TBP group (P<0.05). Conclusion TBP exposure can lead to early developmental abnormalities in zebrafish, manifested as developmental toxicity, thyroid endocrine disruption and neurotoxicity during hatching and early juvenile stages.

Objective:To compare the clinical effect of transaxillary non-inflatable endoscopic surgery and traditional open thyroid surgery in the treatment of PTC. Methods:A retrospective analysis was performed on 342 patients with PTC treated in the Otorhinolaryngology Department of Qilu Hospital of Shandong University from December 2020 to December 2022. There were 73 males and 269 females, aged 16-72 years, who underwent unilateral non-inflatable transaxillary endoscopic thyroid surgery（endoscopic group） and unilateral traditional open thyroid surgery（open group）. There were 108 patients in the endoscopic group and 234 in the open group. Results:The endoscopic group was lower in age（37.1±9.4 vs 43.5±11.2） years and BMI（23.4±3.4 vs 25.7±3.8 ）kg/m² than that in the open group, and the difference was statistically significant（t was 5.53, 5.67 respectively, P<0.01）. There was no significant difference in hospitalization days between the two groups（P>0.05）. The logarithmic curve of the operation time showed a smooth downward trend, and the overall operation time of the endoscopic group was relatively consistent. There was no significant difference in intraoperative blood loss between the endoscopic group（13.3±3.2） mL and the open group（14.7±6.3） mL（P>0.05）, but the operation time（130.1±37.9） min was longer than that in the open group（57.4±13.7） min, and the difference was statistically significant（t=19.40, P<0.01）. There was no significant difference in complications such as temporary recurrent laryngeal nerve injury within 3 days after operation between the two groups（P>0.05）. The aesthetic satisfaction score of the surgical incision and the incision concealment effect score in the endoscopic group were higher than those in the open group, and the difference was statistically significant（P<0.05）. Conclusion:Compared with traditional open thyroidectomy, transaxillary non-inflatable endoscopic thyroidectomy has more advantages in the concealment and aesthetics of postoperative incision. Although the former has longer operation time and more drainage, it is still a safe and feasible surgical method with good postoperative clinical effect.

Background The concentrations of disinfection by-products (DBPs) are varied by different water sources, disinfectants, or treatment processes in Wuxi, and the associated health risks are also different. Objective To understand the levels of trihalomethanes (THMs) and haloacetamides (HAcAms) in drinking water in Wuxi, and their variations by water sources, seasons, disinfectants or treatment processes, aiming to provide technical support for ensuring the safety of drinking water. Methods In dry period (December 2019) and wet period (July 2020), the finished water and tap water (from the beginning, middle, and end of the drinking water distribution network) from 12 centralized water treatment plants in Wuxi were collected to detect the concentrations of THMs and HAcAms in water samples. A purge and trap-gas chromatography-mass spectrometry method was applied to detect trichloromethane (TCM), bromodichloromethane (BDCM), dibromochloromethane (DBCM), and tribromomethane (TBM), and a solid-phase extraction-gas chromatography-mass spectrometry method to detect dichloroacetamide (DCAcAm), trichloroacetamide (TCAcAm), bromochloroacetamide (BCAcAm), dibromoacetamide (DBAcAm), bromodichloroacetamide (BDCAcAm), dibromochloroacetamide (DBCAcAm), and tribromoacetamide (TBAcAm). Analyses and comparisons were made on the concentrations of THMs and HAcAms in drinking water by water sources (the Yangtze River/the Taihu Lake/reservoir), wet/dry seasons, disinfection methods (liquid chlorine/sodium hypochlorite), and treatment processes (conventional treatment/conventional+advanced treatment). Results A total of 96 drinking water samples were collected in Wuxi. THMs were positive in all the water samples (100%), with concentration ranging from 1.027 to 40.225 μg·L⁻¹ and the M (P₂₅, P₇₅) concentration being 24.782 (17.784, 30.932) μg·L⁻¹. None of the 4 THMs exceeded the standard limit of the Standards for drinking water quality (GB 5749-2022 ), and the order of the 4 THMs concentrations from high to low was TCM > BDCM > DBCM > TBM. Five of the 7 HAcAms were detected, the total concentration ranged from 0.137 to 3.288 μg·L⁻¹, and the M (P₂₅, P₇₅) was 0.808 (0.482, 1.704) μg·L⁻¹. The DCAcAm concentration was the highest (2.448 μg·L⁻¹), followed by BCAcAm, while TCAcAm and DBCAcAm were not detected. The M (P₂₅, P₇₅) of the total concentration of THMs in the drinking water from the Taihu Lake was 33.353 (26.649, 36.217) μg·L⁻¹, that of the Yangtze River was 27.448 (24.312, 31.393) μg·L⁻¹, and both were higher than the level of the reservoir [16.359 (2.305, 21.553) μg·L⁻¹] (P<0.05), while the M (P₂₅, P₇₅) of the total concentration of HAcAms in the drinking water from the Taihu Lake was 0.616 (0.363, 0.718) μg·L⁻¹, which was lower than those of the Yangtze River [0.967 (0.355, 2.283) μg·L⁻¹] and the reservoir [1.071 (0.686, 1.828) μg·L⁻¹] (P<0.05). There were no statistically significant differences in the total concentrations of THMs and HAcAms between wet season and dry season, or between different disinfection methods (P>0.05). The M (P₂₅, P₇₅) concentrations of THMs and HAcAms in drinking water after advanced treatment process involving ozone, activated carbon, and membrane were 20.565 (3.316, 27.185) μg·L⁻¹ and 0.623 (0.452, 1.286) μg·L⁻¹ respectively, and were lower than the corresponding values after conventional treatment process, 28.740 (23.431, 35.085) μg·L⁻¹ and 0.934 (0.490, 2.116) μg·L⁻¹ respectively (P＜0.05). Conclusion The concentrations of THMs and HAcAms in drinking water in Wuxi are generally at a low level. The levels of controlled THMs meet the requirements of national standards, and the levels of uncontrolled HAcAms as new DBPs are up to μg·L⁻¹. The concentrations of the two kinds of DBPs in drinking water vary by water sources. The concentrations of THMs and HAcAms produced by the advanced treatment process are lower than that by the conventional treatment process.

Objective    To study the learning curve of minimal invasive coronary artery bypass grafting (MICS CABG) and the influence on the perioperative clinical effects by analyzing operation time. Methods    From March 2012 to November 2020, 212 patients underwent MICS CABG by the same surgeon. Among them, 59 patients (52 males and average age of 62.89±8.27 years) with single vessel bypass grafting were as a single-vessel group and 153 patients (138 males, average age of 59.80±9.22 years) with multi-vessel bypass grafting were as a multi-vessel group. Two sets of operation time-operation sequence scatter plots were made and learning curve was analyzed by cumulative summation (CUSUM) and regression method of operation time. The surgical data of each group before and after the inflection point of the learning curve were compared with the main clinical outcome events within 30 days after surgery. Results    There was no death, perioperative myocardial infarction and stroke in 212 MICS CABG patients and no transfer to cardiopulmonary bypass or redo thoracotomy. The learning curve conformed to the cubic fitting formula. In the single- vessel group, CUSUM (x operation number)=–1.93+93.45×x–2.33×x2+0.01×x3, P=0.000, R2=0.986, the tipping point was 27 patients. In the multi-vessel group, CUSUM (x)=y=2.87+1.15×x–1.29× x2+3.463×x3, P=0.000, R2=0.993, and the tipping point was 59 patients. The two sets of case data were compared before and after the learning curve and there was no statistical difference in main clinical outcomes within 30 days (mortality, acute myocardial infarction, stroke, perioperative blood transfusion rate), ventilator tube, and intensive care unit retention. Conclusion    The learning curve of MICS CABG conforms to the cubic formula, and the process transitions from single to multiple vessels bypass. To enter the mature stage of the learning phase, a certain number of patients need to be done. Reasonable surgical procedures and quality control measures can ensure the safety during the learning phase.

Objective    To investigate the safety and effectiveness of minimally invasive coronary artery bypass grafting (MICABG) through comparing the perioperative clinical effects of conventional surgery and MICABG. Methods    A total of 543 patients in the single medical group of Beijing Anzhen Hospital who underwent beating coronary artery bypass grafting from January 2017 to September 2020 were collected, including 161 patients receiving MICABG (a minimally invasive group, 143 males and 18 females, aged 60.08±9.21 years), 382 patients receiving median thoracotomy (a conventional group, 284 males and 98 females, aged 61.68±8.81 years). The propensity score was used to match 143 patients in each of the two groups, and the perioperative data of the two groups were summarized and analyzed. Results    There was no death, perioperative myocardial infarction or stroke in the minimally invasive group. Compared with the conventional group, the minimally invasive group had longer operation time (296.36±89.4 min vs. 217.80±50.63 min, P=0.000), less number of bypass grafts (2.86±1.03 vs. 3.17±0.78, P=0.005), shorter postoperative hospital stay (6.29±1.46 d vs. 6.78±2.61 d, P=0.031), less drainage on postoperative day 1 (339.57±180.63 mL vs. 441.92±262.63 mL, P=0.001) and lower usage rate of inotropic drugs (9.09% vs. 26.57%, P=0.001). There was no statistical difference between the two groups in postoperative ICU stay ventilator assistance time, blood transfusion rate, secondary thoracotomy rate, or use of mechanical equipment. Conclusion    Reasonable clinical strategies can ensure the satisfactory overall safety of MICABG. In addition, it has the advantages of shorter postoperative hospital stay, less bleeding and smaller dosage of inotropic drugs.

The incidence of thyroid carcinoma is increasing.Because of the special location,patients usually have cosmetic requirements for thyroid surgery.Compared with open surgery,improved Miccoli surgery,total endoscopic surgery,radiofrequency ablation and other minimally invasive surgery have obvious advantages in cosmetology,but the surgical indications are limited.Through incision design and protection,appropriate suture materials,standard suture methods and negative pressure drainage measures,we can effectively reduce the scar formation of open surgery,and improve the cosmetic results.Preoperative individualized treatment should be formulated according to the patient's actual situation,tumor nature,cosmetic needs,hospital conditions and other comprehensive factors.
