Objective To construct two DNA vaccines encoding Gag-Env fusion protein and Tat-Rev-Integrase(C-half)-Vif-Nef fusion protein derived from the first HIV-1 CRF01_AE isolate(AE2f) in Chi-na and to evaluate the immunogenicity in mice. Methods Two DNA vaccines were constructed by inserting the codon optimized and synthesized gag-env fusion gene and tat-rev-integrase(c-half)-vif-nef fusion gene de-rived from AE2f into mammalian expression vector pDRVISV1. 0, the generated DNA vaccines were desig-nated as pSVAE/GE and pSVAE/TRIVN, respectively, and their in vitro expression were determined by Western blot with transfected 293T cells. Mice were i. m. immunized with either pDRVI1.0 as mock control, pSVAE/GE or pSYAE/TRIVN for 4 times at two-week interval. Two weeks following the final im-munization, cellular responses to pool of HIV-1 Env, Gag, Tat, Rev, Intergrase, Vif and Nef peptides were evaluated by ELISPOT assay. Results The construction of DNA vaccine pSVAE/GE and pSVAE/TRIVN was validated by restriction enzyme digestion and bidirectional sequencing. Western blot showed a specific band at molecular mass 220×10~3 in lane of pSVAE/GE transfeeted 293T cell and a specific band at 95×10~3 in the lane of pSVAE/TRIVN. Both DNA vaccines mounted significant specific T cell responses with (3010 ± 566) SFC/10~6 splenocytes for DNA vaccine pSV AE/GE and (948 ± 737) SFC/10~6 spleno-cytes for DNA vaccine pSVAE/TRIVN, whereas the mock control of pDRVISV1.0 only raised marginal T cell responses. Conclusion Both pSVAE/GE and pSVAE/TRIVN were capable of expressing the inserted fusion immunogen genes and able to elicit vigorous cellular immune responses, therefore, these DNA vac-cines are highly immunogenic.

Objective To explore the clinical feasibility of predicting synchronous liver metastases based on MRI radiomics nomogram based on T2WI in rectal cancer. Methods The imaging and clinical data of 261 patients with primary rectal cancer admitted to Zhejiang People′s Hospital from April 2012 to May 2018 were retrospectively analyzed. 101 patients were accompanied by synchronous liver metastasis All cases were divided into training group (n=182) and verification group (n=79). T2WI image of each patient was selected to extract texture features by AK analysis software of GE company. A radiomics signature was constructed after reduction of dimension in training group by the least absolute shrinkage and selection operator (LASSO). Univariate logistic regression was used to select for independent clinical risk factors and multivariate logistic regression along with imaging omics tags were used to construct predictive models and nomogram. ROC was used to assess the accuracy of the nomogram in the training group and to verify them by the validation group. Finally, the clinical efficacy of each patient′s synchronized liver metastasis risk factor was calculated based on the nomogram. Results A total of 328 texture features were extracted from the T2WI. Seven most valuable features were selected after reducing the dimension by LASSO algorithm, including 3 co-occurrence matrices (GLCM) and 4 run-length matrices(RLM). Tumor staging and radiomic signatures were included in the Multifactor logistic regression to build the prediction model and nomogram. The accuracy of predicting SRLM was 0.862 and 0.844 in the training and the verification group, respectively. To evaluate the accuracy of the nomogram, radiomics signature and the tumor staging in all cases were 0.857, 0.832 and 0.663, respectively. There was no significant difference in the number of SRLM cases between the high risk group and the low risk group based on nomogram (P>0.05). Conclusion The radiomics nomogram based on T2WI can be used as a quantitative tool to predict synchronous liver metastases of rectal cancer.

Objective:To evaluate the effect of ultrasound guided modified-subcostal approach to anterior quadratus lumborum block (MSC-AQLB) on postoperative pain relief in open gynecological tumor surgery.Methods:Fifty patients with open gynecological tumor surgery admitted to the Changsha Central Hospital from June 2022 to March 2023 were selected, aged 35-70 years old, with American Society of Anesthesiologist (ASA) grades Ⅰ-Ⅱ. They were randomly divided into two groups using a random number table: an improved subcostal lumbar quadratus anterior block combined with general anesthesia group (MQ group) and a simple general anesthesia group (GA group), with 25 patients in each group. Before induction of general anesthesia, the MQ group received bilateral MSC-AQLB under ultrasound guidance, with 20 ml of 0.4% ropivacaine administered to both sides; The GA group did not receive nerve block. Both groups received intravenous inhalation combined with general anesthesia during the surgery, and both groups received patient-controlled intravenous analgesia (PCIA) with sufentanil after the surgery. The block plane of the MQ group at 5 and 15 minutes after block was recorded, as well as the resting and active (cough) Visual Analogue Scale (VAS) of patients in both groups at extubation (T 1), departure from post anesthesia care unit (PACU) (T 2), postoperative 6 hours (T 3), 12 hours (T 4), 24 hours (T 5), and 48 hours (T 6), the effective and total compressions of the analgesic pump within 48 hours after surgery, the analgesic recovery rate, and postoperative patient satisfaction, the incidence of nausea and vomiting, complications related to nerve block (local anesthetic poisoning, muscle weakness, pneumothorax, bleeding, accidental entry into the abdominal cavity, kidney damage, etc.)were also recorded. Resultsl:The highest and lowest blocking planes of bilateral MSC-AQLB under ultrasound guidance were T 6 and L 1 (at 5 minutes), T 5 and L 2 (at 15 minutes), respectively. The resting and active VAS scores of the MQ group at T 1 to T 6 were significantly lower than those of the GA group (all P<0.05), and the effective press frequency, total press frequency, and analgesic recovery rate of the analgesic pump within 48 hours were significantly lower than those of the GA group (all P<0.05). The postoperative analgesic satisfaction score was higher than that of the GA group ( P<0.05), and the incidence of nausea and vomiting within 48 hours after surgery was significantly lower than that of the GA group ( P<0.05). The MQ group of patients did not experience complications related to nerve block such as kidney injury and muscle weakness. Conclusions:In open gynecological tumor surgery, ultrasound guided MSC-AQLB can effectively reduce postoperative pain scores, reduce the dosage of postoperative analgesics, reduce the incidence of nausea and vomiting, and significantly improve patient satisfaction with pain relief.

Objective:
To explore the risk factors of predicting white matter hyperintensities progression based on radiomics of MRI of whole-brain white matter.
Methods:
The imaging and clinical data of 152 patients with white matter hyperintensities admitted to Zhejiang People′s Hospital from March 2014 to October 2018 were retrospectively analyzed. The whole brain white matter on baseline T1WI images of each patient were segmented by SPM12 software package, and images of white matter were imported into AK software for texture feature extraction and dimensionality reduction. At last, least absolute shrinkage and selection operator(LASSO) was used to calculate the score of radiomics signature of each patient. According to the improved Fazekas scale, patients with WMH progression were divided into three groups: any white matter hyperintensities (AWMH), periventricular white matter hyperintensities (PWMH) and deep white matter hyperintensities (DWMH). Statistical differences of clinical factors and radiomics signature between WMH progression subgroups and non-progression subgroups were compared with independent sample
