Objective To establish a method for evaluating the disinfecting effect of positive-pressure protective hoods by testing the disinfecting effect of canine influenza virus(CIV)on the positive-pressure protective hood with 1％Virkon S disinfectant.Methods The neutralizer was selected considering the characteristics of 1％Virkon S disinfectant in accordance with"Disinfection technical specifications"(2002 edition),and the effectiveness of the neutralizer was verified by determining median tissue culture infectious dose(TTCID50)of different samples inoculated with canine renal cells;in the same environment the effects of viral vectors and environment on viral activity were detected by measuring the TCID50 at different time points when CIV acted on the positive pressure protective hood;the optimal disinfection time was determined by establishing a viral vector model and a viral infiltration and sampling method,combining the results of viral recovery rates by real-time quantitative polymerase chain reaction and enzyme-linked immunosorbent assay and viral titer measurements by TCID50 and 50％egg infectious dose(EID50).Results The phosphate buffer solution of 0.1％lecithin,2％Tween 80 and 0.5％sodium thiosulfate could be used as a neutralizer for 1％Virkon S disinfectant;the viral vectors and environment had no effects on CIV activity at different time points;the average recover rate was 96.12％for the samples inoculated with canine renal cells and 95.98％for the chicken eggs,and 1％Virkon S disinfectant behaved the best 4 min after its action on CIV on the positive-pressure protective hood.Conclusion The method proposed for evaluating the disinfection effect of the positive-pressure protective hood is effective in establishing optimal disinfection conditions for the positive-pressure protective hood.[Chinese Medical Equipment Journal,2023,44(9):33-37]

ObjectiveTo explore the radiosensitization and underlying mechanism of Xuefu Zhuyutang on subcutaneous transplanted esophageal carcinoma. MethodThe subcutaneous xenograft model of human esophageal carcinoma ECA-109 in nude mice was induced and the model mice were divided into a model group， an irradiation group， a Xuefu Zhuyutang group， and a combination group， with six nude mice in each group. After the intervention， the transplanted tumors were removed and weighed， and the tumor inhibition rate of each group was calculated according to the formula. The protein expression of hypoxia-inducible factor-1α （HIF-1α） and vascular endothelial growth factor A （VEGFA） was detected by immunohistochemistry （IHC）. The protein expression of mammalian target of rapamycin （mTOR）， HIF-1α， VEGFA， and vascular endothelial growth factor receptor 2 （VEGFR2） in transplanted tumors was detected by Western blot. The mRNA expression of mTOR， HIF-1α， and VEGFA in transplanted tumors was detected by real-time quantitative polymerase chain reaction （Real-time PCR）. ResultCompared with the conditions in the model group， the tumor weight decreased in the irradiation group and the Xuefu Zhuyutang group （P<0.05）， as well as the combination group （P<0.01）. Compared with the irradiation group， the combination group showed decreased tumor weight （P<0.05）， with tumor inhibition rate of 57.37%. Compared with the model group， the irradiation group， the Xuefu Zhuyutang group， and the combination group showed decreased protein expression of VEGFR2， p-mTOR， HIF-1α， and VEGFA （P<0.05， P<0.01） and reduced mRNA expression of mTOR， HIF-1α， and VEGFA （P<0.05， P<0.01）. Compared with the irradiation group， the combination group showed down-regulated protein expression of VEGFR2， p-mTOR， HIF-1α， and VEGFA （P<0.05， P<0.01） and reduced mRNA expression of mTOR， HIF-1α， and VEGFA （P<0.05， P<0.01）. ConclusionXuefu Zhuyutang can inhibit the growth of transplanted esophageal carcinoma ECA-109 in nude mice and shows an obvious radiosensitization effect in combination with radiotherapy. The mechanism may be related to the inhibition of the mTOR/HIF-1α/VEGFA signaling pathway to improve the hypoxic state of tumors.

Transcatheter arterial chemoembolization (TACE) is the most commonly used method for non-surgical treatment of liver cancer, and it is usually used as an adjuvant therapy in patients who have not developed intrahepatic metastases after surgical resection. Postoperative adjuvant TACE therapy may provide a prognostic benefit in liver cancer patients with high recurrence risk. This article reviews the research progress of adjuvant TACE therapy for liver cancer after radical resection.

Objective: To observe the incidence and treatment of radiation rectal injury complicated with anxiety, depression and somatic symptom disorder. Methods: A cross-sectional survey research method was carried out. Patients with radiation rectal injury managed by members of the editorial board of Chinese Journal of Gastrointestinal Surgery were the subjects of investigation. The inclusion criteria of the survey subjects: (1) patients suffered from pelvic tumors and received pelvic radiotherapy; (2) colonoscopy showed inflammatory reaction or ulcer in the rectum. Exclusion criteria: (1) patient had a history of psycho-somatic disease before radiotherapy; (2) patient was unable to use a smart phone, unable to read and understand the questions in the questionnaire displayed on the phone; (3) patient refused to sign an informed consent form. According to the SOMA self-rating scale, PHQ-15 self-rating scale, GAD-7 and PHQ-9 self-rating scale, the electronic questionnaire of "Psychological Survey of Radiation Proctitis" was designed. The questionnaire was sent to patients with radiation rectal injury managed by the committee through the WeChat group. Observational indicators: (1) radiation rectal injury symptom assessment: using SOMA self-rating scale, radiation rectal injury symptom classification: mild group (≤3 points), moderate group (4-6 points) and severe group (> 6 points); (2) incidence of anxiety, depression and physical disorder: using GAD-7, PHQ-9 and PHQ-15 self-rating scales respectively for assessment; (3) correlation of radiation rectal injury symptom grading with anxiety, depression, and somatic symptom disorder. Results: Seventy-one qualified questionnaires were collected, of which 41 (56.9%) were from Guangzhou. Among the 71 patients, 6 were males and 65 were females; the mean age was (55.7±9.3) years old and 48 patients (67.6%) were less than 60 years old; the median confirmed duration of radiation rectal injury was 2.0 (1.0, 5.0) years. (1) Evaluation of symptoms of radiation rectal injury: 18 cases of mild (25.4%), 27 cases of moderate (38.0%), and 26 cases of severe (36.6%). (2) Incidence of anxiety, depression and somatic disorder: 12 patients (16.9%) without comorbidities; 59 patients (83.1%) with anxiety, depression, or somatic disorder, of whom 2 patients only had anxiety, 1 patient only had depression, 9 only had somatic disorder, 2 had anxiety plus depression, 4 had anxiety plus somatic disorder, 2 had depression plus somatic disorder, and 40 had all three symptoms. (3) correlation of radiation rectal injury grading with anxiety, depression, and somatic symptom disorder: as compared to patients in mild group and moderate group, those in severe group had higher severity of anxiety and somatic symptom disorder (Z=-2.143, P=0.032; Z=-2.045, P=0.041), while there was no statistically significant difference of depression between mild group and moderate group (Z=-1.176, P=0.240). Pearson correlation analysis revealed that radiation rectal injury symptom score was positively correlated with anxiety (r=0.300, P=0.013), depression (r=0.287, P=0.015) and somatic symptom disorder (r=0.344, P=0.003). Conclusions: The incidence of anxiety, depression, and somatic symptom disorder in patients with radiation rectal injury is extremely high. It is necessary to strengthen the diagnosis and treatment of somatic symptom disorder, so as to alleviate the symptoms of patients with pelvic perineum pain and improve the quality of life.

BACKGROUND: The current deep learning diagnosis of breast masses is mainly reflected by the diagnosis of benign and malignant lesions. In China, breast masses are divided into four categories according to the treatment method: inflammatory masses, adenosis, benign tumors, and malignant tumors. These categorizations are important for guiding clinical treatment. In this study, we aimed to develop a convolutional neural network (CNN) for classification of these four breast mass types using ultrasound (US) images. METHODS: Taking breast biopsy or pathological examinations as the reference standard, CNNs were used to establish models for the four-way classification of 3623 breast cancer patients from 13 centers. The patients were randomly divided into training and test groups (n = 1810 vs. n = 1813). Separate models were created for two-dimensional (2D) images only, 2D and color Doppler flow imaging (2D-CDFI), and 2D-CDFI and pulsed wave Doppler (2D-CDFI-PW) images. The performance of these three models was compared using sensitivity, specificity, area under receiver operating characteristic curve (AUC), positive (PPV) and negative predictive values (NPV), positive (LR+) and negative likelihood ratios (LR-), and the performance of the 2D model was further compared between masses of different sizes with above statistical indicators, between images from different hospitals with AUC, and with the performance of 37 radiologists. RESULTS: The accuracies of the 2D, 2D-CDFI, and 2D-CDFI-PW models on the test set were 87.9%, 89.2%, and 88.7%, respectively. The AUCs for classification of benign tumors, malignant tumors, inflammatory masses, and adenosis were 0.90, 0.91, 0.90, and 0.89, respectively (95% confidence intervals [CIs], 0.87-0.91, 0.89-0.92, 0.87-0.91, and 0.86-0.90). The 2D-CDFI model showed better accuracy (89.2%) on the test set than the 2D (87.9%) and 2D-CDFI-PW (88.7%) models. The 2D model showed accuracy of 81.7% on breast masses ≤1 cm and 82.3% on breast masses >1 cm; there was a significant difference between the two groups (P < 0.001). The accuracy of the CNN classifications for the test set (89.2%) was significantly higher than that of all the radiologists (30%). CONCLUSIONS: The CNN may have high accuracy for classification of US images of breast masses and perform significantly better than human radiologists.
