Objective To provide an effective strategy for the prevention and treatment of radiation-induced infections by preparing platelet membrane-modified catalase/silica nanoparticles(PCNP)capable of targeting leukocytes.Methods PCNP and catalase/silica nanoparticles(CNP)were prepared by using platelet membrane,catalase(CAT)and silica,and its biological safety was preliminarily evaluated with cell survival test,hemolysis test and acute toxicity test in mice after tail vein administration;The culture medium,FITC labeled(FITC+)PCNP and FITC labeled(FITC+)CNP were co-incubated with human peripheral blood B lymphocytes(AHH-1)and mouse monocyte macrophages(RAW264.7),respectively.Thus,there were control group,FITC+PCNP group and FITC+CNP group of AHH-1 and RAW264.7 cells.Laser confocal microscopy was used to observe the intracellular fluorescence intensity of PCNP to evaluate the leukocytes targeting function.AHH-1 cells were divided into control,irradiation,platelet membrane,CNP(100 μg/mL)and PCNP(100 μg/mL)groups.After corresponding co-incubation,the cell media were exposed to6 Gy Co60 γ irradiation.The generation of reactive oxygen species(ROS)and cell apoptosis were measured to determine the effect of nanoparticles on reducing radiation injury of leukocytes.Twenty C57BL/6 male mice(weighing 18～20 g)were randomly divided into irradiation group(n=10)and 10 mg/kg PCNP group(n=10).In 2 h after corresponding agents were injected into the mice through tail vein,the mice received whole-body irradiation of 5 Gy Co60 γ ray,and then in 2 h later,they were given intraperitoneal injection of multidrug resistant Acinetobacter baumannii(MDR-AB).The infection inhibitory effect of PCNP after irradiation was evaluated by detecting the bacterial load in main organs.Results The hydration particle of PCNP is 91.3 nm in size,and does not exhibit significant cytotoxicity or hemolytic toxicity at concentrations＜400 μg/mL.Intravenous injection of 20 mg/kg PCNP resulted in normal increase in the body weight but no obvious pathological changes in the major organs such as the heart,liver,spleen,lungs,and kidneys.In AHH-1 and RAW264.7 cells,PCNP showed significant advantages in targeting compared to the FITC+CNP group[(15.45±3.48)%vs(9.33±2.03)%,P＜0.01;(11.25±2.08)%vs(7.06±0.71)%,P＜0.001].PCNP also effectively reduced the generation of ROS[(22.73±3.71)%vs(60.90±9.08)%,P＜0.001]and apoptotic rate[(9.84±0.92)%vs(38.96±3.62)%,P＜0.001]in AHH-1 cells.In in vitro study,bacterial colonization after irradiation showed that there was significantly less MDR-AB colonies in the spleen of mice intervened with PCNP than those of the irradiation group[(17.50±1.38)×104 vs(13.20±2.29)×106 CFU/g,P＜0.001].Conclusion PCNP can effectively inhibit the complications of radiation infection in mice,which is due to its direct protective effect on leukocytes.

In clinical practice, TCM external treatment is used to treat cancer pain, malignant pleural effusion, cancer-related fatigue and other related diseases of non-small cell lung cancer (NSCLC). TCM external treatment can also prevent and treat adverse reactions related to NSCLC treatment measures, such as postoperative cough, radiation-induced lung injury, nausea and vomiting after chemotherapy, bone marrow suppression after chemotherapy, immune and targeted drug-related rash, etc. It mainly uses external use of Chinese materia medica, acupuncture, moxibustion, scraping, acupoint pressing and other methods. Different TCM external treatment method are often used in combination to improve the curative effect. External therapy has been widely used in the treatment of NSCLC related diseases. By balancing yin and yang of viscera, promoting the recovery of body function, it can achieve the role of cancer prevention, improvement of quality of life, control of clinical symptoms, attenuation and effect enhancement.

Objective:To evaluate the diagnostic efficacy and practicality of the Jaundice color card (JCard) as a screening tool for neonatal jaundice.Methods:Following the standards for reporting of diagnostic accuracy studies (STARD) statement, a multicenter prospective study was conducted in 9 hospitals in China from October 2019 to September 2021. A total of 845 newborns who were admitted to the hospital or outpatient department for liver function testing due to their own diseases. The inclusion criteria were a gestational age of ≥35 weeks, a birth weight of ≥2 000 g, and an age of ≤28 days. The neonate′s parents used the JCard to measure jaundice at the neonate′s cheek. Within 2 hours of the JCard measurement, transcutaneous bilirubin (TcB) was measured with a JH20-1B device and total serum bilirubin (TSB) was detected. The Pearson′s correlation analysis, Bland-Altman plots and the receiver operating characteristic (ROC) curve were used for statistic analysis.Results:Out of the 854 newborns, 445 were male and 409 were female; 46 were born at 35-36 weeks of gestational age and 808 were born at ≥37 weeks of gestational age. Additionally, 432 cases were aged 0-3 days, 236 cases were aged 4-7 days, and 186 cases were aged 8-28 days. The TSB level was (227.4±89.6) μmol/L, with a range of 23.7-717.0 μmol/L. The JCard level was (221.4±77.0) μmol/L and the TcB level was (252.5±76.0) μmol/L. Both the JCard and TcB values showed good correlation ( r=0.77 and 0.80, respectively) and agreements (96.0% (820/854) and 95.2% (813/854) of samples fell within the 95% limits of agreement, respectively) with TSB. The JCard value of 12 had a sensitivity of 0.93 and specificity of 0.75 for identifying a TSB ≥205.2?μmol/L, and a sensitivity of 1.00 and specificity of 0.35 for identifying a TSB ≥342.0?μmol/L. The TcB value of 205.2?μmol/L had a sensitivity of 0.97 and specificity of 0.60 for identifying TSB levels of 205.2 μmol/L, and a sensitivity of 1.00 and specificity of 0.26 for identifying TSB levels of 342.0 μmol/L. The areas under the ROC curve (AUC) of JCard for identifying TSB levels of 153.9, 205.2, 256.5, and 342.0 μmol/L were 0.96, 0.92, 0.83, and 0.83, respectively. The AUC of TcB were 0.94, 0.91, 0.86, and 0.87, respectively. There were both no significant differences between the AUC of JCard and TcB in identifying TSB levels of 153.9 and 205.2 μmol/L (both P>0.05). However, the AUC of JCard were both lower than those of TcB in identifying TSB levels of 256.5 and 342.0 μmol/L (both P<0.05). Conclusions:JCard can be used to classify different levels of bilirubin, but its diagnostic efficacy decreases with increasing bilirubin levels. When TSB level are ≤205.2 μmol/L, its diagnostic efficacy is equivalent to that of the JH20-1B. To prevent the misdiagnosis of severe jaundice, it is recommended that parents use a low JCard score, such as 12, to identify severe hyperbilirubinemia (TSB ≥342.0 μmol/L).

Objective:A SARS-CoV-2 pseudovirus(PsV)system was established for neutralizing antibody evaluation and virus entry inhibitor screening.Methods:Lentiviral vector plasmids psPAX2,pCDH-Luc and SARS-CoV-2 Spike(S)protein expres-sion plasmids were co-transfected,and harvested pseudoviral supernatant was used to infect ACE2-293T cells.Protein content of p24 was determined to reflect titer of PsV,and expression of S protein in PsV was detected by Western blot.Neutralization capacity of an S protein monoclonal antibody was evaluated using original strain,D614G,Gamma,Delta,Omicron PsV.Two reported virus entry inhibitors,chloroquine and carrageenin,were used to detect effect on entry of Omicron PsV.Results:Lentiviral vector successfully incorporated S protein.Western blot results showed that S protein mutated at 665Y showed a different cleavage form(90 kD)than wild-type full-length S protein(180 kD).Titer of PsV packaged by three plasmids system was higher.Ratio of S protein expression plasmid,transfer plasmid and packaging plasmid at 1∶3∶3 was optimum condition for viral packaging.Titer of PsV packaged under this condi-tion was over 20 ng/ml.PsV could effectively infect ACE2-293T cells,and double reporter gene GFP and firefly luciferase were expressed obviously,whose chemiluminescence values reached 106.Monoclonal antibodies of S protein effectively neutralized four types of PsVs,but neutralization of original strain was 10～30 times greater than that of variant PsV.Virus entry inhibitors,chloroquine and ι-carrageenan significantly inhibited entry of Omicron PsV.Conclusion:SARS-CoV-2 PsV infection system we conducted can simu-late entry of SARS-CoV-2 successfully.Effective pharmacodynamic evaluation of neutralizing antibodies and virus entry inhibitors can be performed efficiently by the system,which can provide a technical platform for evaluation of neutralizing antibody of SARS-CoV-2 and screening of virus entry inhibitors,and would benefit R&D of anti-SARS-CoV-2 drugs.

Objective:To investigate the correlations of β-catenin expression with the efficacy of tyrosine kinase inhibitor (TKI) and prognosis of patients with advanced lung adenocarcinoma harboring epidermal growth factor receptor (EGFR) mutations.Methods:The clinical data of 125 patients with stage Ⅲ B-Ⅳ lung adenocarcinoma who were treated with first-line EGFR-TKI treatment in the 901st Hospital of Joint Logistic Support Force of Chinese PLA from January 2016 to December 2019 were collected. The expression of β-catenin protein was detected by immunohistochemistry, and subtypes of EGFR mutations were detected by amplification refractory mutation system (ARMS). Correlations of β-catenin expression with clinicopathological features, efficacy of EGFR-TKI and prognosis were analyzed. Twenty-eight pairs of specimens were selected before EGFR-TKI treatment and after resistance to EGFR-TKI to observe the changes of β-catenin expression. Results:Among 125 advanced lung adenocarcinoma patients with EGFR mutations, there were 60 cases of EGFR 19 del, 55 cases of L858R mutation and 10 cases of rare sensitive mutation; 79 cases (63.2%) had reduced membranous expression of β-catenin, 66 cases (52.8%) had ectopic expression in cytoplasm and 28 cases (22.4%) had ectopic expression in nucleus. The positive rates of Napsin A protein in the groups with different abnormal expression patterns of β-catenin were lower than those in the corresponding normal expression groups (all P < 0.001). Patients with International Association for the Study of Lung Cancer (IASLC) grade Ⅲ showed more frequent translocation in cytoplasma and nucleus of β-catenin than patients with IASLC gradeⅠ-Ⅱ (ectopic expression in cytoplasm: χ2 = 3.99, P = 0.046,ectopic expression in nucleus: χ2 = 11.07, P = 0.001). The objective remission rate (ORR) in patients with reduced membranous expression of β-catenin and ectopic expression in nucleus was lower than that in patients with normal membranous expression ( χ2 = 4.66, P = 0.031) and negative ectopic expression in nucleus ( χ2 = 10.22, P = 0.001), and the disease control rate (DCR) in patients with ectopic expression in nucleus was lower than that in the corresponding normal expression group ( χ2 = 10.95, P = 0.001). Patients with ectopic expression of β-catenin in nucleus and cytoplasma had worse progression-free survival (PFS) and overall survival (OS) than the corresponding cytoplasmic and nuclear ectopic expression negative groups (both P < 0.05). Multivariate Cox regression analysis showed that nuclear β-catenin ectopic expression was an independent risk factor for both PFS and OS (PFS: HR = 2.088, 95% CI 1.331-3.274, P = 0.001; OS: HR = 3.656, 95% CI 1.795-7.444, P<0.001). β-catenin membranous expression was reduced in 11 of 28 tissue samples that underwent secondary biopsy compared with pre-treatment ( P = 0.049). Conclusions:β-catenin expression in advanced lung adenocarcinoma with EGFR-sensitive mutations can be used as a molecular marker to predict the efficacy of EGFR-TKI and prognosis of patients.

Chemokine-like factor-like MARVEL transmembrane domain containing member/chemokine-like factor superfamily member (CMTM/CKLFSF) including CKLF and CMTM1-CMTM8 are a new family of proteins linking chemokines and transmembrane superfamilies. CMTM not only have broad chemotactic activities, but also associate with hematopoietic system, immune system, and tumor development and metastasis closely. CMTM proteins are involved in key biological processes of cancer development, which include activation and recycling of growth factor receptors, cell proliferation and metastasis, and regulation of the tumor immune microenvironment. This is a new focus of research on the relationship between CMTM and tumors, because CMTM4/CMTM6 can be considered as a regulator for programmed cell death ligand 1 (PD-L1). This paper reviews the role of CMTM family members on cancer, especially in tumor growth, metastasis and immune escape, summarize the latest findings on the relationship between CMTM and non-small cell lung cancer, and explores the potential clinical value of CMTM as a novel drug target or biomarker.
