Avian coccidiosis, an acute parasitic disease that mainly harms chicks, is widely prevalent across the world, which poses a serious threat to poultry industry. Because of the single prophylactic formulations, veterinary clinical treatment of coccidiosis mainly relies on chemically synthesized agents, polyether ionophores and Chinese herbal medicines. The introduction of novel anticoccidial drugs is slow for a long period of time, and there is an increasing problem of anticoccidial drug resistance following long-term use, which has become an urgent problem to be solved in poultry industry. This review summarizes the levels of anticoccidial drug resistance across China from 2018 to 2023, and analyzes the resistance to various anticoccidial agents in coccidia. It is indicated that the overall prevalence of anticoccidial drug resistance is high in coccidia, and development of novel anticoccidial agents and products with reduced antibiotics use and alternatives of antibiotics is of an urgent need.

OBJECTIVE To explore the efficacy and safety of different doses of bupivacaine liposome (referred to as “LB”) in posterior quadratus lumborum block (QLB) for postoperative analgesia in patients undergoing cesarean section (CS). METHODS In prospective research method, a total of 168 patients undergoing CS admitted to Chongzhou Maternal and Child Health Hospital from June to December 2024 were randomly divided into LB1 group, LB2 group, and LB3 group (LB of 199, 133 and 67 mg, respectively) according to the random number sorting method, with 56 cases in each group. All patients underwent CS after combined spinal-epidural anesthesia, and received patient-controlled intravenous analgesia and bilateral posterior QLB with different doses of LB after the operation. Visual analogue scale score, Ramsay sedation score, the presence of postoperative block planes and muscle strength classification were observed in the three groups of patients at 6, 12, 24, 48 and 72 hours after the operation. The time of the first compression of the analgesic pump, the dosage of sufentanil and butorphanol within 72 hours after surgery, the number of compressions of the analgesic pump, the analgesic rescue rate, the time of initiating lactation, the score of neonatal behavioral neurological assessment (NBNA), the time of postoperative exhaust, the indwelling time of urinary catheter, the length of hospital stay, and the total satisfaction at 72 hours after surgery were compared. The occurrence of adverse reactions within 72 hours after the operation was recorded. RESULTS The resting and motor pain scores, the dosage of sufentanil and butorphanol within 72 hours after surgery, the number of compressions of the analgesic pump, the analgesic rescue rate, and the time of initiating lactation at 6, 12, 24, 48 and 72 hours after surgery in the LB1 group and the LB2 group were significantly lower or shorter than those in the LB3 group(P<0.05). The proportion of postoperative block planes at 24, 48 and 72 hours after surgery, the time of the first compression of the analgesic pump and the total satisfaction in the LB1 group and the LB2 group were significantly higher or longer than those in the LB3 group(P<0.05). The proportion of patients with muscle strength≤grade 3 at 6 hours after surgery in the LB1 group was significantly higher than that in the LB2 and the LB3 groups (P<0.05). There were no statistically significant differences in the Ramsay sedation scores at each time point after surgery, NBNA scores, postoperative exhaust time, urinary catheter indwelling time, the length of hospital stay, as well as the occurrence of adverse reactions among the 3 groups (P>0.05). CONCLUSIONS Compared with 67 mg of LB, 199 mg and 133 mg of LB can improve the postoperative analgesic effect and total satisfaction of CS patients undergoing posterior QLB, reduce the use of postoperative analgesic drugs, and shorten the time to start lactation. Compared with 199 mg and 133 mg of LB, 67 mg of LB has a smaller impact on the motor function of CS patients. All three doses of LB had no significant effect on the neurobehavioral abilities of newborns, and demonstrated comparable sedative efficacy and safety.

Aim To investigate the mechanism by which formononetin (FN) inhibits mitochondrial dynamic-related protein 1 (DRP1) -NLRP3 axis via intervening the generation of ROS to reduce allergic airway inflammation. Methods In order to establish allergic asthma mouse model, 50 BALB/c mice aged 8 weeks were divided into the control group, model group, FN treatment group and dexamethasone group after ovalbumin (OVA) induction. Airway inflammation and collagen deposition were detected by HampE and Masson staining. Th2 cytokines and superoxide dismutase (SOD), catalase (CAT), malondialdehyde (MDA), and IgE levels in bronchoalveolar lavage fluid (BALF) were measured by ELISA, ROS in BEAS-2B cells was assessed by DCFH-DA staining, DRP1 expression in lung tissue and BEAS-2B cells was detected by immunohistochemistry and immunofluorescence, and the DRP1-NLRP3 pathway was analyzed by immunoblotting. Results FN treatment could effectively ameliorate the symptoms of asthmatic mouse model, including reducing eosinophil accumulation, airway collagen deposition, decreasing Th2 cytokine and IgE levels, reducing ROS and MDA production, increasing SOD and CAT activities, and regulating DRP1-NLRP3 pathway-related protein expression, thereby relieving inflammation. Conclusion FN ameliorates airway inflammation in asthma by regulating DRP1-NLRP3 pathway.

Objective:To investigate the efficacy and prognosis of different surgical approaches in sporadic medullary thyroid carcinoma.Methods:A retrospective analysis was conducted on 101 patients with sporadic medullary thyroid carcinoma (MTC) who underwent surgical treatment at the Department of Thyroid Surgery, China-Japan Union Hospital of Jilin University, from Feb. 2009 to Nov. 2023. The patients included 36 males and 75 females, with a male-to-female ratio of 1:2.1. The median age of the patients was 47 years old, with an age range of 21 to 72 years old. The study divided participants into two groups based on their surgical methods: an observation group (78 cases) and a control group (23 cases). The observation group received surgical methods in accordance with expert consensus, while the control group did not. The study compared the efficacy and prognosis of the two groups.Results:Statistical differences were found between the two groups in terms of stage II and III in TNM staging, intraoperative frozen pathological findings, number of lymph node resections in the central group, number of lymph node metastases in the central group, number of lymph node resections in the lateral cervical region, postoperative follow-up time, and five-year postoperative serum procalcitonin (Ctn) levels ( P<0.05) .Both groups of patients obtained a significant decrease in Ctn after surgical treatment. In the observation group, Ctn was at the remission level in 57 cases (73.1%), at the stable level in 13 cases (16.7%), and at the progression level in 8 cases (10.2%), while in the control group, Ctn was at the remission level in 20 cases (86.9%), at the progression level in 3 cases (13.1%), and there were no patients at the stable level after the operation.One patient (1.3 per cent) in the observation group had a recurrence after surgery; Two patients (8.7 per cent) in the control group had a recurrence. Conclusions:Standardised and thorough surgery can maximise the clearance of metastatic lymph nodes, effectively reduce the recurrence rate, achieve better efficacy, and improve the long-term prognosis of patients without increasing the risk of surgery and postoperative complications.

Objective:To establish a prediction model for symptomatic radiation pneumonitis (SRP) after radiotherapy for thoracic cancer based on a longitudinal cohort and dose interval variations.Methods:Clinical data of 587 patients who received thoracic radiotherapy in Department of Radiotherapy of Yunnan Cancer Hospital from July 2022 to June 2023 were retrospectively analyzed. The National Cancer Institute common terminology criteria for adverse events (CTCAE) version 5.0 was used to grade radiation pneumonitis, and clinical factors, traditional independent dosimetric characteristics and dose interval variation characteristics were collected. Features used to predict the occurrence of SRP were screened using genetic algorithms and analyzed the correlation between the selected features and SRP occurrence. Predictive models for SRP occurrence were established using the selected features and evaluated, and the optimal predictive model was visualized using a column chart.Results:The incidence of SRP was 35.94%. Five clinical factors, seven independent dosimetric features and six dose interval variation features were screened out by genetic algorithms to effectively predict the occurrence of SRP. The area under ROC curve (AUC) of clinical factors combined with traditional independent dosimetric factors and dose interval variation factors was 76%. The AUC of clinical factors combined with traditional independent dosimetric factors and that of clinical factors combined with dose interval variation factors was 69% and 67%, respectively. The addition of the characteristics of dose interval variation factors significantly improved the effectiveness of the prediction model.Conclusions:The supplement of the characteristics of dose interval variation factors can significantly improve the performance of the SRP prediction model for thoracic tumors after radiotherapy. The SRP prediction model based on dose interval variations can effectively predict the occurrence of SRP.
