Objective To explore the surgical treatments through anterior and posterior approaches for anterior and posterior compression of cervical spinal cord. Methods The clinical data of 25 cases of anterior and posterior compression of cervical spinal cord from June 1999 to November 2003 were summarized retrospectively. There were 18 males and seven females with age range of 28-56 years (average 36.4 years). Of all,18 cases were with tricolumnae fractures of cervical spine caused by traffic injury,five with cervical herniation and two with malignant macrophage tumor in vertebral body and annex and vertebral lamina. Results All 25 cases underwent internal fixation decompression with I-stage combination operation of anterior and posterior approaches. Of 18 cases with tricolumnae fractures,one died and 17 recovered in various degrees. In five cases with cervical herniation,the positive sign disappeared basically. Two cases of malignant giant-cell tumor appeared metastatic carcinoma in the lungs 10 months after operation. Conclusions The I-stage combination operation of anterior and posterior approaches is an ideal way for the patients suffering from anteropsterospinal compression in cervical spinal cord. It can not only decompress completely the cervical spinal cord,stabilize the wounded cervical vertebra,but also facilitate nursing and function training and be beneficial to the recovery of spinal cord function.

The objective of this study is to explore the application possibility of chitosan/pcDNA-EGFP-TGFPbeta1 nanoparticles in the transfection of synovial-derived mesenchymal stem cells (SDMSCs). Chitosan/pcDNA-EGFP-TGFbeta1 nanoparticles were fabricated through method of ionic crosslinking. The SDMSCs were harvested from rabbit joints and cultured to passage 3. The SDMSCs were then transfected with chitosan/pcDNA-EGFP-TGFbeta1 nanoparticles. Scanning electronic microscope (SEM) was employed to detect the shape and diameter of the nanoparticles. The transfected SDMSCs were examined under the fluorescence microscope and detected through the flow cytometry (FCM). The SEM examination showed that the contour of the fabricated chitosan/pcDNA-EGFP-TGFbeta1 nanoparticles was round and its average diameter was 50 nm. After being cultured for 48 h, the SDMSCs transfected by chitosan/pcDNA-EGFP-TGFbeta1 nanoparticles could be detected under the fluorescence microscope, and the live SDMSCs could also be examined through FCM. The transfection rate was 8% - 10%. Therefore, it suggested that the chitosan/pcDNA-EGFP-TGFbeta1 nanoparticles fabricated through the method of ionic crosslinking could transfect the SDMSCs, but the transfection rate should be improved.

Objective:To analyze the clinical characteristics of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccine breakthrough infections in children, and to provide reference basis for the SARS-CoV-2 vaccination in children.Methods:A total of 97 children aged 3 to 14 years and diagnosed with coronavirus disease 2019 (COVID-19) admitted to Xi′an People′s Hospital (Xi′an Fourth Hospital) from December 27, 2021 to February 7, 2022 were included. According to the COVID-19 vaccination status, the enrolled children were divided into unvaccinated group, partially vaccinated group and fully vaccinated group, and the clinical data of the children in the three groups were collected and compared. Chi-square test, two independent sample t-test and Kruskal-Wallis H test were used for statistical analysis. Results:Totally 97 children including 49 males and 48 females were enrolled, with 87(89.7%) children of mild type, 10(10.3%) children of common type, and no severe or critical case. The proportions of unvaccinated, partially vaccinated and fully vaccinated preschool-aged children (3 to 6 years old) were 56.5%(13/23), 30.8%(12/39) and 17.1%(6/35), respectively, while those of school-aged children (7 to 14 years old) were 43.5%(10/23), 69.2%(27/39) and 82.9%(29/35), respectively. The vaccination proportion in preschool-aged children was significantly lower than that in school-age children ( χ2=9.94, P=0.007). The proportion of the children with fever in fully vaccinated group was 17.1%(6/35), which was lower than that in unvaccinated group (43.5%, 10/23), and the difference was statistically significant ( χ2=4.82, P=0.028). The cycle threshold (Ct) values of the open reading frame ( ORF)1 ab gene in the unvaccinated, partially vaccinated and fully vaccinated groups were 33.77(26.87, 36.58), 35.23 (33.45, 38.57) and 37.12 (34.91, 39.39), respectively, and there was a statistically significant difference among the groups ( H=7.76, P=0.021). The Ct values of the nucleocapsid protein ( N) gene in the three groups were 32.26(25.85, 36.18), 35.12(33.18, 37.96) and 37.26(34.27, 39.24), respectively, and the difference among the groups was statistically significant ( H=7.84, P=0.020). The Ct values of ORF1 ab gene and N gene in fully vaccinated group were higher than those in unvaccinated group, and the differences were statistically significant ( Z=-2.69, P=0.007 and Z=-2.39, P=0.017, respectively). The duration of viral shedding in fully vaccinated children was (9.9±4.1) d, which was shorter than that in unvaccinated children ((12.8±3.7) d), and the difference was statistically significant ( t=2.72, P=0.009). Conclusions:The majority of children with breakthrough infections with SARS-CoV-2 are mild. Vaccination may effectively shorten the duration of viral shedding. And fully vaccination is associated with mild clinical symptoms and lower serum viral load compared to unvaccinated children.
