OBJECTIVETo investigate the inhibitory effect of ampelopsin (AMP) combined with adriamycin (ADR) on growth of human leukemia multidrug resistant cell line K562/ADR.

METHODMTT assay was used to detect the effect of AMP on the cytotoxicity of ADR. Jin's formula was used to analyze the effect of combined drug therapy. The expression of P-glycoprotein (P-gp) on cell membrane of K562/ADR was detected using PE-labeled antibody. Flow cytometry was used to determine the influence of AMP on the intracellular accumulation of ADR.

RESULTAMP at the concentration of 1.25 to 5 mg x L(-1) could significantly reverse the multidrug resistance (MDR) to ADR in K562/ADR cells. Co-administration of 1.25 mg x L(-1) AMP and low concentrations of ADR showed an antagonistic effect, while there was an additional to synergistic effect when the concentration of AMP was above 2.5 mg x L(-1). AMP could decrease the expression of P-gp in a concentration-dependent manner and increase the intracellular accumulation of ADR in K562/ADR cells.

CONCLUSIONAMP could increased the cytotoxicity and the intracellular accumulation of chemotherapeutic drugs in MDR associated tumor cells through inhibiting the efflux of drugs by P-gp. AMP may be a promising MDR modulator.

OBJECTIVE To develop a population pharmacokinetic （PPK） model for mycophenolate mofetil active metabolite mycophenolic acid （MPA） in children with primary IgA nephropathy， explore the factors affecting the pharmacokinetic parameters of MPA， and provide a basis for clinical individualized therapy. METHODS Retrospective collection was conducted on 636 concentrations and clinical data from 47 pediatric patients with primary IgA nephropathy. PPK analysis was carried out by using the nonlinear mixed-effects model； the covariates were tested with a stepwise method. Goodness-of-fit plots， Bootstrap and visual predictive check were employed to evaluate the final model. RESULTS The pharmacokinetics of MPA in children with IgA nephropathy in vivo conformed to the first-order absorption and elimination two-compartment model （objective function value of 3 276.31）. Covariate analysis suggested that body weight and albumin （ALB） levels were significant influencing factors on apparent clearance rate and apparent distribution volume. The typical values of PPK parameters of MPA in the final model were as follows： the central room had a distributed volume of 5.79 L， the clearance rate was 4.06 L/h， the volume of peripheral ventricular distribution was 430.93 L， the clearance rate between compartments was 15.40 L/h， the oral absorption rate constant was 1.29 h－1. After verification， most of the predicted corrected observed concentration points were within the 90% confidence interval of the predicted corrected simulated concentration， indicating that the MPA final model had good predictive performance. CONCLUSIONS The PPK model of MPA in children with primary IgA nephropathy is established in this study， identifying body weight and ALB levels are significant factors affecting MPA metabolism.

【Objective】 To investigate the effects of one-stage additional posterior pedicle screws （PPS） internal fixation on early Cage subsidence after oblique lateral interbody fusion （OLIF）. 【Methods】 We made a retrospective analysis of 118 patients with lumbar degenerative diseases treated with OLIF at the Department of Orthopedics， Sir Run Run Shaw Hospital， School of Medicine， Zhejiang University， from January 2016 to December 2019. We divided the patients into OLIF stand-alone group （58 ones） and OLIF with PPS fixation group （60 ones） according to the surgical procedure. All the patients had preoperative frontal and lateral radiographs of the lumbar spine， and CT and MR scans were performed. The clinical outcomes and reoperation rates of the two groups were compared at immediate postoperative follow-up and at 1， 3， 6 and 12 months. X-ray and CT examinations were performed to assess Cage subsidence in both groups at each postoperative follow-up. 【Results】 There was no statistical difference between the two groups in baseline data and surgical segmentation. Of the 118 patients with 141 discs who underwent OLIF surgery， 58 patients with 68 discs received OLIF stand-alone surgery and 60 ones with 73 discs received OLIF with PPS fixation. There were no significant differences in intraoperative bleeding， complications， or postoperative clinical outcomes between the two groups （P>0.05）， and the Cage subsidence rate was 22.4% in OLIF stand-alone group and 5% in OLIF with PPS fixation group， with significant difference between the two groups （P<0.01）. 【Conclusion】 Both OLIF stand-alone and OLIF additional PPS fixation can achieve good early clinical outcomes， and first-stage additional PPS fixation can significantly reduce the occurrence of Cage subsidence in the early postoperative period after OLIF.

Objective To investigate the value of optical trocar insertion technique in establishing pneumoperitoneum in patients undergoing laparoscopic surgery after previous abdominal surgery. Methods A total of 29 patients, with a history of abdominal surgery, who planned to undergo laparoscopic liver surgery were enrolled and randomly divided into optical trocar insertion group and open approach group. The independent samples t -test was used for comparison of normally distributed continuous data between groups, and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between groups; the Fisher's exact test was used for comparison of categorical data between groups; the Mann-Whitney U test was used for comparison of ranked data between groups. Results There were no procedure-related complications in either group. Compared with the open approach group, the optical trocar insertion group had a significantly shorter time required to establish pneumoperitoneum [35.00 (21.00-46.00) seconds vs 180.00 (152.50-252.50) seconds, U =0, P < 0.001] and a significantly smaller incision length [1.10(1.00-1.20) cm vs 2.80(2.45-3.00) cm, U =0, P < 0.001]. Conclusion Both optical trocar insertion and open approach for establishing pneumoperitoneum is relatively safe in patients undergoing laparoscopic liver surgery after previous abdominal surgery, while optical trocar insertion has the advantages of high efficiency and minimal invasiveness in establishing pneumoperitoneum.
