ObjectiveTo investigate the mechanism by which Shenqi Yiliu prescription reverses cisplatin resistance in ovarian cancer cells by regulating the phosphatidylinositol-3-kinase （PI3K）/protein kinase B （Akt）/mammalian target of rapamycin （mTOR） signaling pathway-mediated glycolysis. MethodsThe human ovarian cancer A2780 cell line was intervened with progressively increasing doses of cisplatin （1 g·L^-1） to establish the cisplatin-resistant cell line A2780cisR， and the cell sensitivity to cisplatin was examined by the cell counting kit-8 （CCK-8） assay. High， medium， and low （39.9， 19.95， 9.98 g·kg^-1） doses of Shenqi Yiliu prescription-containing sera were used to treat A2780cisR cells for 48 h. Glucose consumption and lactate production were measured by the cuvette assay. Enzyme-linked immunosorbent assay （ELISA） was employed to determine the activities of glucose transporter （GLUT）， phosphofructokinase （PFK）， and pyruvate kinase （PK）. Terminal deoxynucleotidyl transferase dUTP nick end labeling （TUNEL） staining was used to detect apoptosis. Western blot was employed to quantify the protein levels of phosphorylated （p）-PI3K， p-Akt， p-mTOR， hexokinase 2 （HK2）， pyruvate kinase M2 （PKM2）， B-cell lymphoblastoma-2 （Bcl-2）， Bcl-2-associated X-protein （Bax）， and B-lymphoblastoma-2 gene-related promoter （Bad）. Real-time PCR was conducted to determine the mRNA levels of HK2， PKM2， Bax， Bcl-2， and Bad. ResultsThe median inhibitory concentration （IC₅₀） of cisplatin on A2780cisR cells was nearly 3 times that on A2780P cells. Compared with A2780P cells， A2780cisR cells showed increased glucose consumption， lactate production， GLUT， PFK， and PK activities， and mRNA and protein levels of p-PI3K， Akt， p-mTOR， HK2， PKM2， Bax （P<0.05）， and decreased apoptosis rate and Bcl-2 expression （P<0.05）. Compared with A2780cisR cells， medium- and high-dose Shenqi Yiliu prescription reduced the glucose consumption， lactate production， GLUT， PFK， and PK activities， and mRNA and protein levels of p-PI3K， Akt， p-mTOR， HK2， PKM2， Bax， and Bad （P<0.05）， while increasing the apoptosis rate and Bcl-2 expression （P<0.05）. ConclusionShenqi Yiliu prescription can inhibit glycolysis mediated by the PI3K/Akt/mTOR pathway to promote apoptosis， thereby reversing cisplatin resistance in ovarian cancer cells.

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.
