ABSTRACT

ObjectiveTo investigate whether elemene(ELE) enhances the anti-glioma efficacy of cabazitaxel(CTX), and prepare a double-targeted cationic liposome(LIP) co-loaded with ELE/CTX for the treatment of glioma, and to achieve the effect of increasing the efficacy and reducing the adverse reactions. Pharmacodynamic tests in vitro were performed to explore the advantages and mechanism of its preparation. MethodELE/CTX@LIP was prepared by high speed shear combined with probe ultrasound, the particle size and potential were characterized by nano-particle size potentiometer, and high performance liquid chromatography(HPLC) was used to determine the encapsulation efficiency and drug loading capacity of CTX/ELE. The cytotoxicity of ELE/CTX in vitro was detected by cell proliferation and activity assay(CCK8). JMP Pro 16 software was used to optimize the process parameters of ELE/CTX@LIP based on encapsulation efficiency. The optimal cationic material type, content and ratio were screened by in vitro cytotoxicity and in vitro cell uptake, on this basis, the dual-targeted cationic liposome T7/arginine glycine aspartate tripeptide sequence(T7/cRGD)-ELE/CTX@CLIP was prepared, the stability of morphology and particle size were characterized, and the effect of T7/cRGD-ELE/CTX@CLIP on the apoptosis inducing ability and cell cycle regulation ability of glioma cells was analyzed by cell cycle and apoptosis. ResultELE/CTX showed stronger anti-glioma activity on C6 and RG2 cells. The results of in vitro cytotoxicity and in vitro cell uptake showed that the amount of cationic material was 0.10% of the total content. The optimum ratio of T7, cRGD and phospholipids was 1∶1∶50. T7/cRGD-ELE/CTX@CLIP[1,2-dilinoleyloxy-3-dimethylaminopropane(Dlin-MC3-DMA)] and T7/cRGD-ELE/CTX@CLIP[1,2-dimyristoyl-rac-glycero-3-methoxypolyethylene glycol 2000(DMG-PEG2000)] showed multi-level spherical nanostructures with particle sizes of 146.0, 111.3 nm, respectively, and were stable in serum. In vitro cytotoxicity results showed that T7/cRGD-ELE/CTX@CLIP had higher cytotoxicity to glioma cells than single-targeted liposomes or dual-targeted non-cationic liposomes. T7/crGD-ELE/CTX@CLIP affected the apoptosis and cycle of glioma cells, the results showed that ELE/CTX combined with liposomes could more effectively activate the apoptosis channel and inhibit the proliferation of glioma cells, and the use of T7/cRGD short peptide and cation modification enhanced the ability of apoptosis induction. ELE/CTX could effectively block glioma cell cycle at G2/M phase, and the effect was enhanced after T7/cRGD targeted modification. ConclusionELE can enhance the anti-glioma effect of CTX. The preparation parameters of ELE/CTX@LIP are stable and feasible. Combined with the in vitro efficacy test, the anti-glioma mechanism of T7/cRGD-ELE/CTX@CLIP is preliminarily revealed.

ABSTRACT

ObjectiveTo explore the effects of different intensity of wearable lower limb rehabilitation robot-assisted training on walking function, lower limb motor function, balance function and functional independence of stroke patients. MethodsFrom November, 2021 to December, 2022, 60 stroke patients hospitalized in Beijing Bo'ai Hospital were randomly divided into control group (n = 20), observation group 1 (n = 20) and observation group 2 (n = 20). All the groups received routine rehabilitation, while the control group received routine walking training 30 minutes a day, the observation group 1 received wearable lower limb rehabilitation robot-assisted training 30 minutes a day, and the observation group 2 received wearable lower limb rehabilitation robot-assisted training 60 minutes a day, for four weeks. They were assessed with Functional Ambulation Category scale (FAC), Fugl-Meyer Assessment-Lower Extremities (FMA-LE), Berg Balance Scale (BBS) and Rivermead Mobility Index (RMI) before and after treatment. ResultsOne case in the observation group 1 and three cases in the observation group 2 dropped down. The FAC, FMA-LE, BBS and RMI scores improved in all the three groups after treatment (|Z| > 3.448, |t| > 8.102, P < 0.001), and there was no significant difference in all the indexes among the three groups (|H| < 4.643, F = 1.454, P > 0.05); however, the improvement of BBS score was more in the observation group 1 than in the control group (P < 0.05), and the improvement of all the indexes was more in the observation group 2 than in the control group (P < 0.05). ConclusionThe wearable lower limb rehabilitation robot-assisted training may promote the recovery of walking function, lower limb motor function, balance function and functional independence of stroke patients, and high-intensity training seems to be more effective.

These patients were randomly divided into a control group ( n = 52) and an observation group ( n = 52). All patients underwent radical mastectomy. The patients in the observation group received breast prosthesis implantation in addition to radical mastectomy. Operative time, length of hospital stay, psychological state scores before and 3 months after surgery, aesthetic recovery effect of breast 3 months after surgery, WHO Quality of Life Rating Scale (WHOQOL-100) score, postoperative occurrence of subcutaneous effusion, and flap necrosis were compared between the two groups. Results:There was no significant difference in operative time between the two groups ( P > 0.05). The length of stay in the observation group was (10.89 ± 2.34) days, which was significantly shorter than (21.06 ± 3.82) days in the control group ( t = 16.37, P < 0.001). At 3 months after surgery, the scores of the Self-rating Anxiety Scale (SAS), Hamilton Anxiety Scale (HAMA), Self-rating Depression Scale (SDS), and Hamilton Depression Scale (HAMD) in both groups were significantly lower than those before surgery. At 3 months after surgery, the scores of SAS, HAMA, SDS, and HAMD in the observation group were (39.02 ± 5.21) points, (19.02 ± 2.51) points, (16.03 ± 2.55) points, and (41.89 ± 3.56) points, which were significantly lower than (50.76 ± 4.85) points, (28.97 ± 2.66) points, (53.41 ± 4.56) points, and (24.88 ± 2.32) points in the control group ( t = 11.89, 19.62, 14.77, 18.51, all P < 0.001). At 3 months after surgery, the excellent and good rate of breast recovery in the observation group was [96.15% (50/52)], which was significantly higher than [69.23% (36/52)] in the control group ( Z = 5.40, P < 0.001). At 3 months after surgery, the scores of overall health, physical function, social function, cognitive function, and role function in each group were significantly higher than those before surgery, and the sole of emotional function in the observation group was significantly higher than that in the control group. At 3 months after surgery, the scores of overall health, physical function, social function, cognitive function, and role function in the observation group were (55.87 ± 12.70) points, (55.89 ± 12.34) points, (35.05 ± 11.25) points, (55.87 ± 7.88) points, and (58.77 ± 14.05) points, respectively, which were significantly higher than (43.75 ± 12.58) points, (47.50 ± 12.87) points, (28.04 ± 10.13) points, (39.87 ± 8.06) points, (32.05 ± 13.85) points, (74.52 ± 14.88) points in the control group ( t = 4.89, 3.39, 3.34, 10.24, 9.77, P < 0.001, 0.001, < 0.001, < 0.001, < 0.001, 0.003). The incidence of complications in the observation group was [3.85% (2/52)], which was significantly lower than [17.31% (9/52), χ2 = 4.98, P = 0.026] in the control group.

ABSTRACT

Objective:To explore the clinical characteristics and genetics of a pedigree with Stargardt disease, and investigate the pathogenicity of ABCA4 (ATP binding cassette subfamily A member 4) gene mutations in Stargardt disease.Methods:The proband was admitted to the Second People′s Hospital of Jinan in May 2021 due to diminution of vision. The proband was diagnosed with Stargardt disease according to the clinical diagnostic criteria of Stargardt disease. Detailed ophthalmological examinations was also performed on family members of the proband. Genomic DNA were extracted from the proband and the family members, and the whole exon sequencing was performed to find pathogenic gene mutations. The hazard of mutations was analyzed by polyphen-2, SIFT and MutationTaster websites. Sanger sequencing was used to verify the mutations. Conserved analysis of homologous species and 3-dimensional (3D) molecular model of the protein were used to analyze the pathogenicity.Results:Ophthalmological examinations showed reduced binocular vision, macular atrophy and "bull′s eye sign" in the proband and there was no abnormal signs and symptoms among the family members. Through whole exon sequencing analysis and Sanger sequencing verification, the compound heterozygous mutations (c.215G>A and c.6563T>C) of ABCA4 gene were co-segregated with this disease in this family. SIFT, Polyphen-2 and MutationTaster predicted that these two mutations were pathogenic. Conservative analysis and 3D molecular model of protein showed that mutations could cause changes in protein structure and affect protein function.Conclusion:The compound heterozygous mutations (C.215G>A and C.6563T>C) of ABCA4 gene are the pathogenic mutations of Stargardt disease in this pedigree.

ABSTRACT

The coronavirus disease 2019 (COVID-19) pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has occasioned worldwide alarm. Globally, the number of reported confirmed cases has exceeded 84.3 million as of this writing (January 2, 2021). Since there are no targeted therapies for COVID-19, the current focus is the repurposing of drugs approved for other uses. In some clinical trials, antiviral drugs such as remdesivir (Grein et al., 2020), lopinavir/ritonavir (LPV/r) (Cao et al., 2020), chloroquine (Gao et al., 2020), hydroxychloroquine (Gautret et al., 2020), arbidol (Wang et al., 2020), and favipiravir (Cai et al., 2020b) have shown efficacy in COVID-19 patients. LPV/r combined with arbidol, which is the basic regimen in some regional hospitals in China including Zhejiiang Province, has shown antiviral effects in COVID-19 patients (Guo et al., 2020; Xu et al., 2020). A retrospective cohort study also reported that this combination therapy showed better efficacy than LPV/r alone for the treatment of COVID-19 patients (Deng et al., 2020).

ABSTRACT

Objective: To analyze the clinical features∗ imaging findings, diagnostic methods, pathomorphology and prognosis of the patients with primary pulmonary diffused large B-cell lymphoma (DLBCL) with the multiple ground glassy nodule shadows in the lungs as the main manifestation, and to improve the clinicians' understanding of the primary pulmonary DLBCL. Methods: The clinical data of a patient with primary pulmonary DLBCL were collected. The main manifestation in CT examination of the patient was multiple massive ground glass nodule shadows in the lungs. The initial diagnosis was pneumonia. The final diagnosis of primary pulmonary DLBCL was confirmed by pathology and immunohistochemistry examination. The related literatures were reviewed. Results: The female patient was admitted to hospital due to cough and expectoration as the first manifestations. There were no obvious positive signs in the physical examination. The CT examination results showed multiple ground glassy nodular shadows in both lungs. The tumor markers∗ lymph node color Doppler ultrasound, PET-CT∗ bone marrow biopsy∗ pathological biopsy and the other related examinations were performed∗ and the related treatment were given. The PET-CT results showed the multiple ground glass nodule in both lungs complicated with increasing of partial metabolism∗ and the pathological and immunohistochemical results suggested that the patient was non-Hodgkin DLBCL originated from the activated B cells outside the germinal center, and the final diagnosis was primary pulmonary DLBCL. The patient was given R CHOP regimen regularly. The patient received chest CT examination 3 months later, and the results showed that the massive nodule shadows in both lungs were disappeared. Conclusion: The clinical features and imaging findings of the patient with primary pulmonary DLBCL are not specific, its diagnosis ultimately relies on the pat homo pho logical and immunohistochemical examination results; the degree of malignancy of primary pulmonary DLBCL is high, and the prognosis is poor; when there are multiple ground glass nodule shadows in the lungs, the disease should be taken into account.

ABSTRACT

Familial acne inversa (AI) is an autoinflammatory disorder that affects hair follicles and is caused by loss-of-function mutations in γ-secretase component genes. We and other researchers showed that nicastrin (NCSTN) is the most frequently mutated gene in familial AI. In this study, we generated a keratin 5-Cre-driven epidermis-specific Ncstn conditional knockout mutant in mice. We determined that this mutant recapitulated the major phenotypes of AI, including hyperkeratosis of hair follicles and inflammation. In Ncstn;K5-Cre mice, the IL-36a expression level markedly increased starting from postnatal day 0 (P0), and this increase occurred much earlier than those of TNF-α, IL-23A, IL-1β, and TLR4. RNA-Seq analysis indicated that Sprr2d, a member of the small proline-rich protein 2 family, in the skin tissues of the Ncstn;K5-Cre mice was also upregulated on P0. Quantitative reverse-transcription polymerase chain reaction showed that other Sprr2 genes had a similar expression pattern. Our findings suggested that IL-36a might be a key inflammatory cytokine in the pathophysiology of AI and involved in the malfunction of the skin barrier in the pathogenesis of AI.

ABSTRACT

Objective To construct a CaME141G fusion protein-expressing plasmid,and to express,purify,and identify the activity of the recombinant protein. Methods The 141st site of the wild type CaM,E (GAG),was mutated to G (GGG),using site-specific mutagenesis technology. Escherichia coli BL-21 was transformed with the mutant plasmid. The GST-CaME141G fusion protein was mass-cultured and induced for expression. Subsequently,the GST-CaME141G fusion protein was purified using GS-4B beads. PreScission protease was applied to remove the GST,the Bradford method used to determine the concentration of purified protein,and SDS-PAGE used to detect its relative molecular weight and purity. The GST pull-down assay was used to study the protein's biological activity. Results The CaME141G protein was successfully purified at a high concentration and purity. The protein could interact with PreIQ protein fragments from the myocardial CaV1. 2 calcium channel C terminal,in a CaME141G concentration-dependent manner. Therefore,CaME141G has the ability to bind with the CaV1. 2 calcium channel. Conclusion This study successfully constructed a CaME141G fusion protein-expressing plasmid and purified the CaME141G protein. This lays a foundation for regulating the function of CaM mutations in the myocardial CaV1. 2 calcium channel,and for the study of its relationship with diseases of the cardiovascular system.

ABSTRACT

Objective To explore the expression of long noncoding RNA ( lncRNA) RN7SK and its screening value in clinical diagno-sis of gastric cancer. Methods The expression of lncRNA RN7SK in gastric cancer cells and paired gastric cancer tissues were meas-ured by qRT-PCR. The screening efficacy was detected by the receiver operating characteristic ( ROC) curve. Results The expression levels of lncRNA RN7SK in gastric cancer lines SGC-7901(3.91±0.53),MGC-803(3.44±0.29),HGC-27(4.04±0.87)and BGC-823 (4.30±1.13) were markedly higher than that in human gastric mucosal epithelial cell line GES-1, and the difference had statistical sig-nificance(1.02±0.27, t=12.33, 7.48, 7.20 and 4.90, P<0.05). The expression of RN7SK was up-regulated in 85.5% (47/55) of gastric cancer tissues while down-regulated in the the other 8 tissues ( 14. 5%) . The area under ROC curve ( AUCROC ) of lncRNA RN7SK expression in gastric cancer patients was 0.827 and the 95% confidence interval (CI) was from 0.746 to 0.907. When the cut-off value was 0.618, the sensitivity and specificity were 0.836 and 0.782 respectively. Conclusion The level of lncRNA RN7SK should be overexpressed in gastric cancer tissues so that it may have high screening efficacy and could be used as a potential molecular marker for the diagnosis of gastric cancer.

ABSTRACT

Objective@#To investigate the effect of transforming growth factor-β1 (TGF-β1) on HBV replication and protein expression in HepG2.2.15 cells with steatosis, as well as the association of TGF-β1 with suppressor of cytokine signaling-3 (SOCS-3) mRNA and sterol regulatory element-binding protein-1c (SREBP-1c) mRNA during the steatosis of HepG2.2.15 cells.@*Methods@#The cells were divided into HepG2/HepG2.2.15 cell control groups (C1/C2 groups) and HepG2/HepG2.2.15 cell steatosis groups (F1/F2 groups). 5 ng/ml TGF-β1 was added to the two cell systems for intervention to establish TGF-β1 intervention groups (T1/T2 groups) and steatosis+TGF-β1 intervention groups (TF1/TF2 groups). A time-resolved fluorescence analyzer was used to measure HBsAg and HBeAg, and quantitative real-time PCR was used to measure HBV DNA, SOCS-3 mRNA, and SREBP-1 mRNA. A one-way analysis of variance and a factorial analysis were used for the statistical analysis of data.@*Results@#TGF-β1 significantly reduced the level of HBeAg in C2 group (P = 0.034) and the levels of HBsAg (P < 0.001) and HBeAg (P = 0.004) in F2 group. There was an interaction between steatosis and TGF-β1 in inhibiting HBsAg. In addition, TGF-β1 significantly reduced the mRNA expression of SOCS-3 in C1, F1, C2, and F2 groups (P < 0.05) and significantly increased the mRNA expression of SREBP-1c in C1, F1, C2, and F2 groups (P < 0.05), suggesting that there was an interaction between steatosis and TGF-β1 in downregulating the mRNA expression of SOCS-3 and upregulating the mRNA expression of SREBP-1c.@*Conclusion@#TGF-β1 does not affect HBV duplication in HepG2.2.15 cells and can inhibit the expression of HBsAg and HBeAg. TGF-β1 can downregulate the mRNA expression of SOCS-3 and upregulate the mRNA expression of SREBP-1c.

ABSTRACT

Objective:To establish a method for the determination of 11 trace elements in white vaselin. Methods:The contents of Mg,Al,Fe,Co,Ni,Cu,Zn,As,Cd,Hg and Pb in white vaselin were determined by inductively coupled plasma mass spectrome-try (ICP-MS). The parameters of ICP-MS were as follows:the Argon gas pressure was 0.6 MPa,the helium pressure was 0.12 MPa, the scan times were 200,the flush time was 45 s,the sampling time was 45 s and the internal standard was added online. Results:The linear relationship between concentration and response value of each element standard solution was within the range of 0-100 ng· m L-1. Except the correlation coefficients of Mg and Fe were 0.998 and 0.997,that of the other elements was all above 0.999. The recoveries of Mg,Fe,Ni,Zn,As and Pb were 74.9%-83.0%,those of Cd and Hg were 87.5%-94.4%,and those of Al,Co and Cu were 107.6%-118.7%. The detection limit of Mg, Al, Fe, Co, Ni, Cu, Zn, As, Cd, Hg and Pb was 1.9,0.59,0.61,0.16, 0.33,1.5,1.7,0.09,0.12,0.70 and 1.6 ng·ml-1,respectively. Among the 67 samples,the contents of Mg,Al,Fe,Ni,Cu, Zn, As and Hg were all detected out,while those of Co,Cd and Pb were only detected out in some samples. Conclusion:The method has the advantages of simple operation and high sensitivity,which can satisfy the determination of trace elements. It is suggested to se-lect 4 elements (Mg,Al,Fe and Ni) as the evaluation indices for white vaselin.
