OBJECTIVE To study the mechanism of Compound lizard powder on reversing cisplatin（DDP） resistance in resistant gastric cancer cell MKN45/DDP through nuclear factor-κB （NF-κB）/SNAIL signaling pathway. METHODS MKN45/DDP cells were divided into model group （20% normal rat serum）， DDP group （1.3 μg/mL DDP+20% fetal bovine serum） and Compound lizard powder low- and high-dose drug-containing serum+DDP groups （17.2， 68.8 g/kg Compound lizard powder 20% drug-containing serum+1.3 μg/mL DDP）. The viability， apoptosis and intracellular autophagosome of MKN45/DDP cells were detected. The content of microtubule-associated protein 1 light chain 3 （LC3） in the cell supernatant was detected. The expressions of B-cell lymphoma 2 （Bcl-2）， Bcl-2-related X protein （Bax）， as well as the protein expression levels of phosphorylated NF-κB p65 （p-NF-κB p65） and SNAIL were detected. The molecular mechanism of Compound lizard powder in improving DDP resistance was further clarified by using NF-κB pathway agonist tumor necrosis factor-α （TNF-α）. RESULTS Compared with model group and DDP group， the cell survival rates of Compound lizard powder low- and high-dose drug-containing serum+DDP groups were significantly decreased （P＜0.05）， while the levels of apoptosis and autophagic death were significantly increased （P＜0.05）. The expression levels of Bcl-2 （except for the compound lizard powder low-dose drug-containing serum+DDP group）， p-NF-κB p65 and SNAIL protein in MKN45/DDP cells were significantly decreased （P＜0.05）. The content of LC3 and expression of Bax protein were significantly increased （P＜0.05）. High-dose Compound lizard powder drug-containing serum+DDP could effectively reverse the down-regulation of LC3 Ⅱ/LC3 Ⅰ and Bax protein expression induced by TNF- α （P＜0.05）. CONCLUSIONS Compound lizard powder drug-containing serum combined with DDP can induce apoptosis and autophagic death of MKN45/DDP cells by inhibiting NF-κB/SNAIL signaling pathway， thus reversing DDP resistance of cells.

Prone position ventilation (PPV) is an important protective strategy for lung ventilation, widely used in clinical practice, especially since the novel coronavirus infection pandemic. Since PPV is a non-physiological position, improper implementation and management can lead to serious adverse events such as pressure injury, facial edema, unplanned extubation and (or) reintubation, and even asphyxia. At present, preventive and protective strategies are mainly used to manage PPV-related complications in clinical practice. These strategies not only increase the workload of medical staff and the use of consumables, but also increase the medical cost of patients, further burdening patients and their families economically. To overcome the above problems, the medical staff of the department of critical care medicine of Tianjin Third Central Hospital designed a prone position head auxiliary support device and obtained a national utility model patent (patent number: ZL 2022 2 1751906.3). The device consists of annular plate, folding plate, support frame, reflector and wheel bodies. It serves to reduce pressure on the head and facial skin, while also exposing the mouth, nose, eyes, and ears to the hollow position of the annular plate according to the patient's position. At the same time, the patient's face or side skin can be observed through the lower reflector. The height of the annular plate was adjusted by adjusting the support frame, and the head was raised to reduce facial edema. The setting of strip groove, through hole and hook can sort out the facial pipeline, keep the drainage unobstructed, prevent catheter displacement and unplanned extubation, and has certain clinical promotion and practical value.

Objective To predict the target and molecular mechanism of Huayu Xiaopi decoction in the intervention of Precancerous lesions of gastric cancer(PLGC)based on network pharmacology and molecular docking technology,and to conduct experimental verification.Methods A total of 60 SPF SD male rats were randomly selected as blank control,and the other rats were replicated in PLGC model.After successful modeling,the rats were randomly divided into model group,folic acid group(2 mg·kg-1·d-1),Huayu Xiaopi decoction high,medium and low dose groups(24.8,12.4,6.2 g·kg-1·d-1),which were continuously administered for 90 days.The body mass and food intake of rats at 3 h were recorded,and the gastric histopathology was observed by HE staining.Network pharmacology and molecular docking techniques were used to predict the potential targets of Huayu Xiaopi decoction in PLGC intervention,and the core targets were verified by Western blot technique.Results Compared with the blank group,the body mass and 3 h food intake of rats in the model group were significantly decreased(P<0.05),the gastric mucosa of rats was significantly thinner,the glands were significantly reduced and disordered,and the intestinal metaplasia goblet cells and a large number of inflammatory cells were visible in some areas.Compared with the model group,the body mass and 3 h food intake of rats in each administration group were improved to varying degrees.Huayu Xiaopi Decoction improved significantly in medium and high doses(P<0.05),the gastric mucosa was repaired in different degrees,the glandular arrangement tended to be orderly,and the inflammatory cells in the interstitial were gradually reduced.The results of network pharmacology and molecular docking showed that TP53,JUN and MAPK3/1(ERK1/2)were the core targets of Huayu Xiaopi decoction in the intervention of PLGC.Molecular biological detection results showed that compared with blank group,the protein phosphorylation levels of TP53,c-Jun and ERK1/2 in gastric tissue of model group were significantly increased(P<0.05).Compared with model group,the protein phosphorylation levels of TP53,c-Jun and ERK1/2 in gastric tissue of rats in all administration groups were decreased to different degrees,and significantly decreased in Huayu Xiaopi decoction high-dose and medium-dose groups(P<0.05).Conclusion Huayu Xiaopi Decoction can significantly improve the survival condition of PLGC rats and promote gastric mucosal repair,the specific mechanism of which may be related to the decrease of ERK1/2,c-Jun and TP53 protein phosphorylation levels in gastric tissue of PLGC rats,and then regulate the downstream signaling molecular response.

Objective To investigate the impact of statistical uncertainty per control point(SUpCP)on dose calculation on volumetric modulated arc therapy(VMAT)for rectum cancer,and to analyze the accuracy and efficiency of calculation.Methods 19 patients with rectum cancer undergoing radiotherapy were selected.The initial VMAT plans were generated on Monaco TPS using SUpCP=3,then changed SUpCP in the dose calculation process as follow:10 SUpCPs(1～10)for each patient,and totally190 VMAT dose distributions were obtained.For plan evaluation,Dmax,Dmean,D95%,V50,homogeneity index(HI),conformity index(CI)of the planning target volume(PTV),dissymmetric variations of bladder,small intestine and femoral head,and time calculation(Time)were analyzed.Patient specific quality assurance(PSQA),dose deviation of isocenter(ΔDISO)and passing rate of three-dimensional dose distribution(γ33,γ32,γ22)between calculated and delivered radiation doses were measured.Results AsSUpC increased,Dmax and HI of PTV,Dmax of bladder were increased,but D95%and V50 of PTV,Time,γ32 and γ22 were decreased(P<0.05).Dmax and CI of PTV,Dmean of bladder,Dmax and Dmean of small intestine and femoral head,ΔDISO and γ33 showed no statistical significance(P>0.05).When ΔDISO<1%,gamma passing rate>90%for all VMAT plan.When SUpCP<6,Dmax of PTV<110%of the prescribed dose was obtained;while SUpCP>2,time for dose calculation was less than 5 min.Conclusion For VMAT plan of rectum cancer on Monaco TPS using XVMC algorithm,3%～5%of statistical uncertainty per control point for dose calculation,and 3%2 mm or 2%2 mm gamma criteria for three-dimensional dose verification is recommended.This study provides clinical application basis for precise dose calculation of VMAT plan of rectum cancer.

Objective To analyze the diagnostic value of systemic immune inflammation index(SII)and systemic inflammation response index(SIRI)in rheumatoid arthritis(RA).Methods A total of 470 RA pa-tients diagnosed in the hospital from January to December 2023 were selected.According to the results of anti-cyclic citrullinated peptide(anti-CCP)antibody and rheumatoid factor(RF),RA was divided into four groups:anti-CCP antibody and RF negative group(52 cases),anti-CCP antibody positive RF negative group(70 cases),anti-CCP antibody negative RF positive group(18 cases),anti-CCP antibody and RF positive group(330 cases),and 300 healthy subjects were selected as control group.After calculating SII and SIRI in each group,Kruskal-Wallis was used to examine the difference between SII and SIRI in the anti-CCP antibody and RF negative group,anti-CCP antibody positive RF negative group,anti-CCP antibody negative RF positive group,anti-CCP antibody and RF positive group of RA patients and the control group,and the receiver operat-ing characteristic(ROC)curve was drawn to evaluate the diagnostic efficacy of SII and SIRI in the anti-CCP antibody and RF negative group,anti-CCP antibody positive RF negative group,anti-CCP antibody negative RF positive group,anti-CCP antibody and RF positive group of RA patients.Results SII and SIRI in four groups of RA patients were significantly higher than those in control group(P＜0.05).The area under the curve(AUC)of SII in evaluating the four groups of RA patients were 0.689,0.724,0.709,and 0.774,respec-tively.SIRI had an AUC of 0.679,0.729,0.679,and 0.772 in the evaluation of the four groups of RA pa-tients,respectively.Conclusion SII and SIRI are both elevated in patients with RA,and have certain predictive value for RA.

Objective To investigate the transcriptome differences of ovarian cancer cells after cisplatin(DDP)resistance,and to find potential antagonists based on this screening.Methods DDP-resistant cell line A2780-DDP was constructed with A2780 cells as the research object.Through transcriptome sequencing anal-ysis,the key factors of DDP resistance were found and verified by quantitative real-time PCR(qPCR)and Western blot experiments.Through the screening of small molecule inhibitors,CCK-8 cell viability assay was used to find potential antagonists.Results A2780-DDP were successfully constructed,and it was found that there was no difference in cell proliferation after drug resistance,but the ability of cell invasion and migration was enhanced.Through transcriptome sequencing analysis,it was found that ITGB7 and Akt may be the key genes of A2780-DDP,and qPCR and Western blot showed that they were highly expressed in A2780-DDP.CCK-8 results showed that triptolide(TPL)and Olaparib had good inhibitory effects in DDP-resistant cell lines.Conclusion The ITGB7/Akt pathway plays an important role in DDP resistance,and potential DDP re-sistance antagonists such as TPL can provide new ideas for the treatment of ovarian cancer.

Objective To compare the clinical efficacy of three different therapies,including transjugular intrahepatic portosystemic shunt(TIPS)treatment,endoscopic treatment and medication treatment,combined with transhepatic arterial chemoembolization(TACE)in treating primary liver cancer complicated by portal hypertension and upper gastrointestinal bleeding.Methods A total of 105 patients with primary liver cancer associated with portal hypertension and upper gastrointestinal bleeding,who were admitted to the No.980 Hospital of PLA Joint Logistics Support Forces of China to receive treatment between January 2014 and June 2020,were enrolled in this study.According to the therapeutic scheme,the patients were divided into TIPS+TACE group(TIPS group,n=25),endoscopy+TACE group(endoscopy group,n=30),and medication+TACE group(medication group,n=50).The clinical efficacy,recurrence rate of bleeding,incidence of hepatic encephalopathy,and survival rate were compared between each other among the three groups.Results The differences in the postoperative 6-month,12-month and 24-month recurrence rates of bleeding between each other among the three groups were statistically significant(all P＜0.05).In TIPS group,the portal vein pressure decreased from preoperative(38.47±9.35)mmHg(1 mmHg=0.133 kPa)to postoperative(25.24±5.68)mmHg,the difference was statistically significant(P＜0.05).After treatment,the hemoglobin level in the three groups showed varying degrees of elevation,which in the TIPS group and endoscopy group were better than that in the medication group,the differences were statistically significant(P＜0.05).In all three groups,the differences in the recurrence rate of bleeding between postoperative 6-month value,12-month value and 24-month value were statistically significant(all P＜0.05).The postoperative 6-month,12-month and 24-month recurrence rates of bleeding in the TIPS group were lower than those in the endoscopy group and the medication group,and the differences were statistically significant(P＜0.05).The postoperative 12-month and 24-month recurrence rates of bleeding in the TIPS group were lower than those in the endoscopy group,and the differences were statistically significant(P＜0.05).The postoperative 12-month and 24-month recurrence rates of bleeding in the endoscopy group were lower than those in the medication group(P＜0.05),and the difference in the postoperative 6-month recurrence rate of bleeding between the two groups was not statistically significant(P＞0.05).The postoperative 6-month and 12-month incidences of hepatic encephalopathy in the TIPS group were higher than those in the endoscopy group and the medication group,the differences were statistically significant(P＜0.05),while the differences in the postoperative 6-month and 12-month incidences of hepatic encephalopathy between the endoscopy group and the medication group were not statistically significant(P＞0.05),and the differences in the postoperative 24-month incidence of hepatic encephalopathy between each other among the three groups were not statistically significant(P＞0.05).No statistically significant difference in the 6-month mortality existed between TIPS group and endoscopy group(P＞0.05),and the 6-month mortality of both TIPS group and endoscopy group was remarkably lower than that of the medication group(P＜0.05).The postoperative 12-month mortality and 24-month mortality in TIPS group were lower than those in the endoscopy group and the medication group,and the differences were statistically significant(P＜0.05),but the differences in the postoperative 12-month mortality and 24-month mortality between the endoscopy group and the medication group were not statistically significant(P＞0.05).Conclusion For primary liver cancer associated with portal hypertension and upper gastrointestinal bleeding,TIPS combined with TACE can effectively control tumor progression and prolong survival.(J Intervent Radiol,2024,32:33-37)
