Objective To analyze the retrieval rate of inferior vena cava filter(IVCF)and its safety,and to make a histological analysis of the filter attachment substances.Methods The clinical data of 234 patients with IVCF,who were admitted to Affiliated Tenth People's Hospital,Tongji University,to retrieve IVCF between June 2020 and May 2023,were retrospectively analyzed.The retrieval success rate,complications and filter attachment substances were statistically analyzed,and the nature of the attachment substances was examined by using histological staining.Results The retrieval success rate in the 234 patients was 91.03％(213/234).In 17 patients the retrieval of IVCF was abandoned due to the filter capturing the thrombus,and in 4 patients the retrieval of IVCF failed due to tilting of the filter.No complications such as vena cava perforation,symptomatic pulmonary embolism and hemorrhage occurred in all patients during perioperative period.Of the 213 patients whose filter was successfully removed,the filter attachment substances was found in 156 patients.Histological staining of the filter attachment substances demonstrated that the main component of these substances was a mixed thrombus with a small amount of cellulose degeneration.Further analysis revealed that the incidence of filter attachment substances in ≤14-day group was lower than than that in＞14-day group,and the difference between the two groups was statistically significant(x2=6.791,P=0.009);and the incidence of filter attachment substances in the non-anticoagulant group was lower than that in the anticoagulant group,and the difference between the two groups was statistically significant(x2=7.774,P=0.005).Conclusion The retrieval rate of retrievable IVCFs is quite high and the retrieval procedure carries less complications,therefore,it is safe to use retrievable IVCFs in clinical practice.However,the formation of tiny thrombosis within the filter after the placement of filter cannot be ignored,which should be seriously considered in the clinical work.

Objective:To evaluate the quality of critical patient handover practice between emergency room and intensive care unit (ICU) nurses, and to provide a basis for structured handover process.Methods:From March to July 2023, a total of 223 pairs of nurses in emergency room and ICU (including EICU) of 5 Class 3 Grade A general hospitals in Suzhou were selected as the research objects by using cross-sectional survey method and convenience sampling method. Self-designed general information questionnaire and Patient Handover Practice Quality Scale were used to investigate the included 223 pairs of nurses in emergency room and ICU on the current situation of handover time and quality.Results:A total of 211 pairs of nurses were included, including 286 females (67.8%) and 136 males (32.2%). The average age of emergency department nurses was (27.31 ± 2.17) years old, and ICU nurses was (26.96 ± 3.04) years old. The total scores of the patient handover practice Quality Scale for nurses in the emergency room and ICU were (45.25 ± 6.26) and (43.55 ± 7.19) points respectively, and the scores of the information transmission dimension were (20.47 ± 5.43) and (17.66 ± 3.45) points. The scores of common understanding dimension were (7.59 ± 2.31) and (8.58 ± 2.46) points. The scores of work atmosphere dimension were (7.93 ± 2.11) and (8.39 ± 2.29) points. The scores of handover situation dimension were (5.33 ± 1.30) and (5.70 ± 1.53) points, and the differences were statistically significant ( t values were - 6.35-4.22, all P<0.05). There were statistically significant differences in the scores of handover practice quality between emergency room nurses and ICU nurses according to specialization, education background, working years and job category ( t values were - 4.91-2.56, all P<0.05). Conclusions:Emergency room nurses and ICU nurses have different requirements and expectations for handover procedures, so it is necessary to build a structured handover practice framework and carry out personalized handover practice training, in order to achieve the consistency of handover content and improve the quality of critical patients handover practice.

Osteoporosis is an important cause of internal fixation loosening after spinal surgery.Cement-augmented pedicle screw instru-mentation(CAPSI)technique is the most widely used technique in clinical practice to improve the stability of pedicle screw,mainly applied in osteoporosis and revision surgery,which included conventional solid pedicles crews and fenestrated/cannulated pedicle screws technique.CAPSI technique may cause cement leakage and pulmonary embolism,and there is no consensus on its indications or technical points.Therefore,this article reviews the research progress of CAPSI,in order to provide relevant reference for clinical practice.

Aim To investigate the enhanced efficacy and reduced toxicity of GanoExtra in combination with cyclophosphamide(CTX)on inhibiting lung metastasis and immune function in mice.Methods The CCK-8 method was used to verify the cytotoxic effects of Gano-Extra on MCF-7 and 4T1 tumor cells.In vivo experi-ment,a mouse model of lung metastasis of breast canc-er was established by injecting 4T1 tumor cells into the tail vein,which was divided into four groups including 4T1 model group,CTX group,GanoExtra group and GanoExtra+CTX group.The control group was set.After 21 days,the mice were euthanized under anes-thesia,and the body weight of the mice was recorded.Average lung index and spleen index were calculated.The mouse spleen lymphocyte transformation experi-ment was used to determine the activity of spleen cells.The NK cell activity assay was used to determine the activity of NK cells.Blood cells were determined in mouse blood samples.Flow cytometry was used to de-termine the levels of CD4+and CD8+T cells in blood samples.ELISA was used to measure the levels of TNF-α and IL-6 in serum.HE staining was used to ob-serve the pathological morphological changes in tumors and various tissues;and CFSE staining was used to de-termine the proliferative effect of GanoExtra on CD8+cells.Results In vitro GanoExtra at 50 mg·L-1 sig-nificantly inhibited the activity of MCF-7 and 4T1 tumor cells.In the breast cancer pulmonary metastasis model,compared with the model group,the spleen in-dex and blood WBCs content were significantly re-duced,while the activity of NK cells,spleen cells,and the proportion of RBCs,CD 3+and CD 8+T cells in the blood were significantly increased.At the end of the treatment,compared with the CTX group,the number of lung metastases and lung index of the Gano-Extra+CTX group were significantly reduced,and the levels of HGB,CD8+cells,IL-6,and TNF-α in the blood of mice were significantly increased.GanoExtra at 10 mg·L-1 significantly promoted the proliferation of CD8+T cells in vitro.Conclusions GanoExtra can enhance the inhibitory effect of CTX on tumor metasta-sis,alleviate adverse reactions such as splenomegaly and pulmonary enlargement caused by CTX,and have a health-promoting function of promoting the prolifera-tion of CD8+T cells to enhance the immune efficacy of the body.

Objective:To investigate the application value of single-sperm sequencing in resolving the carrier status of preim-plantation genetic testing(PGT)for chromosomal structural rearrangements in Robertsonian translocations.Methods:Haplotypes were constructed by single-sperm isolation combined with single-sperm sequencing for a patient with 45,XY,der(13;14)(q10;q10).Twenty single-sperm samples were isolated by mechanical braking and subjected to whole-genome amplification(WGA),and then the Asian Screening Array(ASA)gene chip was used to detect the 183 708 single nucleotide polymorphisms(SNP)of the WGA products.The single sperm associated with the translocation that could be used as haplotype inference was detected by copy number variation(CNV)sequencing,and the chromosomal haplotypes with normal and Robertsonian translocations were inferred.Three biopsy samples of embryonic trophoblast cells were used as the objects.After whole-genome amplification,high-throughput sequencing was employed to determine the status of the translocation chromosome carried by the embryos.The available blastocysts were selected for transfer,and the amniotic fluid samples were taken at 18 weeks of gestation to confirm whether the fetus carried the pathogenic muta-tion.Results:A total of 6 037 SNP sites were screened by single-sperm sequencing,and 30 sites selected to distinguish normal and translocation haplotypes.Preimplantation haplotype analysis showed that all the three embryos were euploids without Robertsonian translocation chromosome.Genetic testing of amniotic fluid in the second trimester confirmed that the karyotype of the fetus was 46,XN,carrying no Robertsonian translocation chromosome.Conclusion:For male carriers of Robertsonian translocation,single sperm sequencing can be used to screen SNP sites to construct haplotypes for distinguishing normal and Robertsonian translocation em-bryos,and to provide a basis for embryo selection by preimplantation chromosomal structural genetic testing.
