Objective To construct eukaryotic enhanced green fluorescent protein (EGFP) expressing recombinant plasmid, pEGFP-C1-hnRNP A1, which contains coding sequence of human hnRNP A1 (heterogeneous nuclear ribonucleo-protein A1), and to perform cellular localization analysis of EGFP tagged hnRNP A1 under stress. Methods Total RNA was isolated from HeLa cell used for synthesis of first-strand cDNAs using reverse primers that are specific for the 3′-un-translated region of hnRNP A1. hnRNP A1 gene fragments were then amplified by touch-down PCR from those cDNAs and inserted into pEGFP-C1 fluorescent bearing vector through EcoRⅠ/BamHⅡdouble enzyme digestion and T4 DNA Ligase connection. The recombinant pEGFP-C1-hnRNP A1 plasmid was transfected into HeLa cells and green fluorescent tagged fusion proteins was examined by Western blot and confocal fluorescence microscopy. Co-localization of EGFP-hnRNP A 1 with poly (A)+mRNA (the marker of the stress granules), or DCP1a (the marker of processome) were detected by RNA fluores-cence in situ hybridization and immunofluorescence. Results The pEGFP-C1-hnRNP A1 was sequenced and digested cor-rectly by restriction single/double enzyme. The green fluorescent fusion protein was also detected in transfected HeLa cell by Western blot and confocal fluorescence microscopy. EGFP-hnRNP A1 co-localizes with poly(A)+mRNA, but not DCP1a. Conclusion Recombinant eukaryotic plasmid of pEGFP-C1-hnRNP A1 was constructed successfully and expressed effec-tively. EGFP tagged hnRNP A1 takes part in forming stress granules.

Objective To construct eukaryotic Flag (DYKDDDDK) expressing recombinant plasmids, pCMV-N-Flag-SND1-No1/2, which contain the coding sequence of human SND1-No1(from 1st AUG)or SND1-No2 (from 2nd AUG), and perform the cellular localization analysis of Flag-tagged SND1-No1/2 under stress condition to study the function of the two AUG in the SND1 containing stress granules formation. Methods The gene fragments of SND1-No1/2 were amplified by PCR from the whole SND1 transcript and inserted into pCMV-N-Flag expressing vector through BamHI/EcoRI double en-zyme digestion and T4 DNA Ligase connection. The recombinant pCMV-N-Flag-SND1-No1/2 plasmids were transfected in-to HeLa cells and the expression of Flag-SND1-No1/2 fusion proteins was examined by Western blotting assay. Immunofluo-rescence assay was performed to detect the co-localization of Flag-SND1-No1/2 with endogenous SND1 granule. Results The pCMV-N-Flag-SND1-No1/2 were sequenced and digested correctly by restriction single/double enzyme. The Flag-tagged SND1-No1/2 fusion proteins were also detected in transfected HeLa cell by Western blotting assay. Both of them showed the co-localization with endogenous SND1 granule. Conclusion The recombinant eukaryotic plasmids of pCMV-N-Flag-SND1-No1/2 were constructed successfully and expressed effectively. The depletion of 1st AUG failed to af-fect the formation of SND1 containing stress granules.

Objective:To prepare three kinds of liposomes with different solvent medium named common liposomes, ethanol liposomes and propylene glycol liposomes,screen and optimize the preparation process,and investigate the stability preliminarily. Methods:Common liposomes were prepared by a thin film dispersion method, and ethanol liposomes and propylene glycol liposomes were prepared by an injection method. With the same formula compositions,the size distribution of common liposomes was studied with hydration time, water bath temperature and rotation speed. The size distribution of ethanol liposomes and propylene glycol liposomes was studied different volume ratio of alcohol to water, stirring speed and mode of membrane passmg. An orthogonal design was adopted to obtain the optimal preparation technology based on the influences. Preliminary stability of the three different solvent medium liposomes was evaluated respectively on 0,1st,15th and 30th day using the changes of morphology and the mean particle size as the indicators. Results:The results of orthogonal test showed that the best preparation method for common liposomes was as follows:the hydration time was 60 min,the water bath temperature was 50℃ and the rotation speed was 200 r·min-1. The best preparation method for ethanol liposomes and propylene glycol liposomes was as follows:the volume ratio of alcohol to water was 1:2,the stirring speed was 1 000 r·min-1and the mode of membrane passing was 0.45 μm at first and then changed to 0.22 μm. Under the optimum preparation conditions, the three liposomes were closed monolayer or multilayer cystic spherosomes. The average diameter of common liposomes, ethanol liposomes and propylene glycol liposome was (1 016.2 ± 135.6),(578.7 ± 89.2) and (351.4 ± 53.8) nm, respectively. All the three liposomes were unstable during the one-month observation period. After the 15-day storage, obvious delamination appeared.Conclusion:Three different solvent medium liposomes prepared with the best process are in micro-scale or nano-scale. They are in poor stability, which should be freshly prepared before use.

Objective:To examine whether the mixed infection rate in pertussis infants is significantly higher than that in non-pertussis infants with respiratory tract infection, to explore the mixed infection pathogen distribution in pertussis infants, and to provide reference for clinical diagnosis and treatment.Methods:A case-control study was conducted on 118 nasopharyngeal swabs collected from infants who applied for clinical pertussis etiological testing (culture and specific nucleic acid detection of Bordetella pertussis) in Beijing Children′s Hospital, Jiaxing Maternity and Child Health Care Hospital and Wuhu No.1 People′s Hospital from August 2018 to January 2021.According to the pertussis etiological testing results, the patients were divided into the pertussis group (65 cases) and non-pertussis group (53 cases). Thirty-three pairs of cases were matched according to age, onset season and city.All nasopharyngeal swabs were tested for infections of other pathogens using FilmArray RP2, which can detect 21 respiratory infection pathogens.The mixed infection rate was compared between groups by Chi- square test. Results:According to the FilmArray RP2 test results, 56.9%(37/65) cases in pertussis group and 15.1%(8/53) cases in the non-pertussis group were positive for multiple pathogens, and the difference was statistically significant ( χ2=21.651, P<0.001). The top 5 mixed infection pathogens in pertussis infants were human rhinovirus/enterovirus (HRV/EV) (38.5%, 25/65), parainfluenza virus (PIV) (18.5%, 12/65), respiratory syncytial virus (RSV) (10.8%, 7/65), coronavirus (Cov) (10.8%, 7/65), and adenovirus (ADV) (7.7%, 5/65). The mixed infection rates of the pertussis group in spring, summer, autumn and winter were 46.2% (6/13), 58.3%(14/24), 55.6%(5/9), and 63.2%(12/19), respectively.Comparison of matched and unmatched cases achieved similar results. Conclusions:Among clinical suspected pertussis infant specimens, the mixed infection rate in confirmed cases is tremendously higher than that in non-pertussis infants.The main mixed infection pathogens in pertussis infants are HRV/EV, PIV, RSV, Cov, and ADV.Mixed infection in pertussis children commonly occurs in four seasons, with the highest incidence in winter.

Objective:To explore the effect and safety of endoscopic tubular musculoskeletal tumor surgery (ETMS) technology in spinal tumors.Methods:Clinical data were retrospectively collected from 18 spinal tumor patients who were treated with ETMS technology at Tianjin Medical University Cancer Institute and Hospital ( n=16) or the Affiliated Hospital of Qingdao University ( n=2) from November 2022 to December 2023. The total cohort included 11 males and 7 females, with the age at 60.3±8.6 years (range of 41-76). Two cases were diagnosed with benign tumors, four patients were diagnosed with spinal hematologic malignancies while other 12 cases were patients with spinal metastases. After localization under the C-arm X-ray machine, the spinal endoscopic channel is established using dilators. Soft tissue is dissected under endoscopic guidance to create an artificial cavity. Subsequently, the saline medium relied upon by the spinal endoscopic technique is removed, and posterior decompression and tumor curettage are performed using tubular techniques. Frankel grade classification and paraplegia index were used to evaluate the improvement of postoperative function and the VAS score was performed in pain scoring. The surgical complications and tumor evaluation were observed by postoperative outpatient and telephone follow-up. Results:The ETMS technology was successfully completed in all 18 patients with the mean operation time of 240.3±80.2 min. The median of intraoperative bleeding was 200.0(172.5, 350.0) ml and the mean postoperative drainage was 131.4±69.5 ml. The median value of postoperative hospitalization days was 6.0(4.0, 10.25) d. The paraplegia index decreased from 1.5(0, 3.0) preoperatively to 0(0, 1.25) postoperatively ( Z=-2.599, P=0.009). All the patients presented an improvement in Frankel grading after surgery except for one patient (downgrading from grade E to grade D). There was significantly difference in Frankel grading between preoperative and postoperative groups ( Z=2.812, P=0.005). The median value of preoperative VAS score was up to 5.5(4.0, 7.0) while the median value at postoperative, one month after surgery and three months after surgery were 1.5(1.0, 2.25), 1.0(0, 1.0) and 0(0, 1.0), respectively (χ 2=44.641, P<0.001). The 3-month postoperative VAS improvement rate was 91.2% (range 75%-100%). During a mean follow-up period of 7.6±6.2 months, none of the 18 patients presented surgical complications or tumor recurrence at surgical region. Only one patient died at 3.2 months after surgery until the last follow-up due to respiratory failure after lung tumor progression. The mean survival of the total cohort was up to 13.3 [95% CI (11.5, 15.0)] months. The 16 cases with spinal metastases or spinal hematological malignancies had a mean survival of 13.2 [95% CI (11.3, 15.0)] months. Conclusion:The ETMS technology presented good efficacy and safety in treatment of spinal tumors with low blood supply and with diameter less than 5cm.
