Objective To compare the efficacy of MRI-transrectal ultrasound(TRUS)software fusion-guided biopsy and cognitive fusion-guided biopsy for detecting prostate cancer(PC).Methods Data of 120 patients with suspected PC(127 lesions)who underwent transperineal prostate biopsy with 2-3 times of target biopsy(TB)and 10 times of system biopsy were retrospectively analyzed.According to TB guidance methods,73 cases(78 lesions)received MRI-TRUS software fusion-guided biopsy were classified into group A,and 47 cases(49 lesions)received cognitive fusion-guided biopsy were classified into group B.The positive rate of PC,clinic significant PC(csPC)and PC in different sized lesions by TB were compared between groups,and the positive rate of PC between 2 or 3 times TB was also compared within each group.Results The positive rate of PC and csPC detected by TB was 55.13%(43/78)and 39.74%(31/78)in group A,53.06%(26/49)and 34.69%(17/49)in group B,respectively,no significant difference was found(all P＞0.05).The positive rate of PC in lesions with the maximum diameter≤10 mm detected by TB in group A was higher than that in group B(P＜0.05),but no significant difference of lesions with the maximum diameter＞10 mm and＜15 mm nor≥15 mm was found between groups(all P＞0.05).No significant difference of positive rate of PC was found between 2 and 3 times TB in group A(P＞0.05),while positive rate of PC of 3 times TB was significantly higher than that of 2 times TB in group B(P＜0.05).Conclusion MRI-TRUS software fusion-guided biopsy had positive rate of PC and csPC similar to that of cognitive fusion-guided biopsy,but was helpful for reducing times of TB and increasing detecting rate for lesions with the maximum diameter≤10 mm.

Objective:To analyze the image characteristics of gastrointestinal stromal tumor(GIST) and leiomyoma under white-light endoscopy and ultrasound endoscopy, so as to establish a nomogram model and to validate its performance.Methods:From August 1, 2019, to December 1, 2022, the clinical data of 224 patients with GIST or leiomyoma who underwent endoscopic ultrasound examination at the First Affiliated Hospital of Soochow University were retrospectively analyzed. The 224 patients were divided into the modeling group of 145 cases (78 cases of GIST and 67 cases of leiomyoma), and the validation group of 79 cases (41 cases of GIST and 38 cases of leiomyoma). The basic data of patients, parameters of white-light endoscopy and ultrasound endoscopy were screened to establish a binary logistic regression model and draw a nomogram. The receiver operating characteristic curve (ROC) was drawn, and the area under the curve (AUC) was used to evaluate the diagnostic efficiency of the model, and calibration curve was used to evaluate the consistency of predicted and observed probabilities. The model′s performance was compared with the diagnostic results of junior physicians (attending physicians) and senior physicians (associated chief physician). Decision curve analysis (DCA) was performed to evaluate the net benefit of the model. Independent sample t-test and chi-square test were used for statistical analysis. Results:Under white-light endoscopy, there were statistically significant differences in the lesion locations (esophagus: 0 vs. 56.7% (38/67); cardia: 11.5% (9/78) vs. 13.4% (9/67); gastric: 88.5% (69/78) vs. 29.9% (20/67)) and tumor morphyology (spherical or spheroid: 80.8% (63/78) vs. 28.4% (19/67); shuttle: 19.2% (15/78) vs. 71.6% (48/67)) between GIST and leiomyoma in the modeling group ( χ2=64.51 and 46.37, both P<0.001). Under ultrasound endoscopy, the proportion of patients with GIST whose lesions originated from the muscularis propria layer, with indistinct borders and with internal hyperechoic area were all higher than those of patients with leiomyoma (96.2% (75/78) vs. 62.7% (42/67); 53.8% (42/78) vs. 13.4% (9/67); 35.9% (28/78) vs. 10.4% (7/67)), and the differences were statistically significant ( χ2=25.91, 25.82 and 12.75, all P<0.001). Based on the logistic regression model, a nomogram model was established with age, tumor morphology, lesion origin, boundary clarity, and hyperechoic foci as predictive indicators. In the modeling group, the accuracy of nomogram model in the diagnosis of GIST and leiomyoma was 89.7% and 83.6%, respectively. In the validation group, the sensitivity, specificity, and accuracy in GIST and leiomyoma diagnosis of the nomogram model and senior physicians were all higher than those of junior physicians in differentiating GIST from leiomyoma (90.2%, 87.8% vs. 82.9%; 81.6%, 84.2% vs. 78.9%; 86.1%, 86.1% vs. 81.0%, respectively), and the sensitivity, specificity, and accuracy of the nomogram model were equal to those of senior physicians in differentiating GIST from leiomyoma. The AUCs of the nomogram model in the modeling group and validation group were 0.932 (95% confidence interval 0.891 to 0.974) and 0.916 (95% confidence interval 0.854 to 0.978), respectively. The calibration curves of the model indicated that the consistency between the predicted probabilities and observed probabilities was good, and DCA suggested good clinical net benefits of the model. Conclusion:The model exhibits good test efficiency, discrimination, prediction consistency and clinical net benefit when age, tumor morphology, lesion origin, boundary clarity, and hyperechoic foci are selected as indicators.

Objective To investigate the changes of OAT expression in bone cells in chronic renal failure(CRF)and involved mechanism,and to explore the effect of OAT expression on bone metabolism.Methods Ra-ndomly divide the rats into a control group(n=6)and a model group(n=6).The model group established a rat chronic renal failure model using"single nephrectomy+adenine gavage"method,and the red blood cell(RBC)and hemoglobin(HGB)of the rat body were measured using a blood routine analyzer;Measure indicators such as creatinine(Cr),urea nitrogen(BUN),uric acid(UA),blood calcium(Ca2+),and blood phosphorus(P3+)using a fully automated biochemical analyzer;Pathological examination of rat kidneys;X-ray examination of rat tibia;Immunohistochemical examination of bone tissue OAT1 level.Results The bone density of the model group rats is lower than that of the control group;The calcium and phosphorus metabolism of rats in the model group was in metabolic disorder,and the OAT1 value of bone tissue binding was much lower than that of the control group(P= 0.0018),which was statistically significant.(P=0.0018)Conclusion Chronic renal failure affected the binding ability of OAT1 in bone tissue,leading to the metabolic disorder for calcium absorption and phosphorus metabolism,thus aggravating renal osteodystrophy(P<0.05).

Objective: To explore the mediating effect of parental hostile attribution bias on depression and anxiety between parents and children, so as to provide the reference for the promotion of children's mental health. Methods: Students of grades 2-6 in two public primary schools in Linping District, Hangzhou City and their parents were investigated using stratified sampling method in November 2022. Emotions of children were surveyed using Depression Self-Rating Scale for Child (DSRSC) and Screen for Child Anxiety Related Emotional Disorders (SCARED), while emotions and hostile attribution bias of parents were surveyed using Self-rating Depression Scale (SDS), Self-rating Anxiety Scale (SAS) and Social Cognitive Screening Questionnaire (SCSQ). Mediating effect of parental hostile attribution bias on depression and anxiety between parents and children was analyzed using a structural equation model. Results: Totally 300 questionnaires were allocated, and 263 valid questionnaires were recovered, with an effective rate of 87.67%. There were 137 boys (52.09%), and 126 girls (47.91%), with a mean age of (9.95±1.44) years. There were 69 fathers and 194 mothers investigated. The prevalence of depression among parents was 27.00%, the prevalence of anxiety among parents was 4.18%, and the median score of hostile attribution bias was 1.00 (interquartile range, 2.00). The prevalence of depression among children was 11.03%, and the prevalence of anxiety among children was 29.66%. Parents' depression and anxiety affected children's depression and anxiety directly (effect value=0.270, 95%CI: 0.131-0.436), and also indirectly affected children's depression and anxiety by increasing their hostile attribution bias (effect value=0.028, 95%CI: 0.004-0.082), with the mediating effect contributed 9.40% of the total effect. Conclusion Parents' depression and anxiety affect children's depression and anxiety directly or indirectly through hostile attribution bias.

【Objective】 To investigate the trend of neutralizing antibody level in plasma donors who received the 3rd shot of inactivated novel coronavirus vaccine. 【Methods】 Three commercial ELISA kits for novel coronavirus neutralization antibody detection, manufactured by Company A, B and C, were chosen and screened by Pseudotype Neutralization Test from December 2021 to June 2022. A total of 410 plasma samples from 64 plasma donors who received the 3rd shot of inactivated novel coronavirus vaccine and there after donated plasma within six months were detected by the selected ELISA kit from July to October, 2022. The data were analyzed by Excel 2013 and SPSS 26 software. 【Results】 The high-throughput ELISA kit for SARS-CoV-2 neutralizing antibody detection, manufactured by Company A, was selected for further antibody titer detection. The mixed plasma titers were 1 337.34, 1 148.89, 852.19, 681.38, 556.44 and 457.19 U/mL from 1 to 6 months, respectively, after the 3rd shot of vaccine. The neutralizing antibody titer level began to increase around 7 days after the 3rd shot of vaccine injection and peaked (peak range: 264.07-2 208.39 U/mL, median: 569.34 U/mL) at 1 month (range: 9-43 days, median: 22 days), and then gradually decreased (P<0.05). 【Conclusion】 The neutralizing antibody titer of plasma donors who received the 3rd shot of inactivated novel coronavirus vaccine began to rise around 7 days after vaccination, which reached the peak value at around 1 month and then gradually decreased.

As a promising modality for cancer therapy, photodynamic therapy (PDT) still acquired limited success in clinical nowadays due to the extremely serious hypoxia and immunosuppression tumor microenvironment. To ameliorate such a situation, we rationally designed and prepared cascade two-stage re-oxygenation and immune re-sensitization BSA-MHI148@SRF nanoparticles via hydrophilic and hydrophobic self-assembly strategy by using near-infrared photodynamic dye MHI148 chemically modified bovine serum albumin (BSA-MHI148) and multi-kinase inhibitor Sorafenib (SRF) as a novel tumor oxygen and immune microenvironment regulation drug. Benefiting from the accumulation of SRF in tumors, BSA-MHI148@SRF nanoparticles dramatically enhanced the PDT efficacy by promoting cascade two-stage tumor re-oxygenation mechanisms: (i) SRF decreased tumor oxygen consumption via inhibiting mitochondria respiratory. (ii) SRF increased the oxygen supply via inducing tumor vessel normalization. Meanwhile, the immunosuppression micro-environment was also obviously reversed by two-stage immune re-sensitization as follows: (i) Enhanced immunogenic cell death (ICD) production amplified by BSA-MHI148@SRF induced reactive oxygen species (ROS) generation enhanced T cell infiltration and improve its tumor cell killing ability. (ii) BSA-MHI148@SRF amplified tumor vessel normalization by VEGF inhibition also obviously reversed the tumor immune-suppression microenvironment. Finally, the growth of solid tumors was significantly depressed by such well-designed BSA-MHI148@SRF nanoparticles, which could be potential for clinical cancer therapy.

Objective:To evaluate the efficacy of bedside gastric ultrasound in guiding enteral nutrition therapy in the patients with spontaneous cerebral hemorrhage.Methods:Sixty-one patients with spontaneous intracerebral hemorrhage in the intensive care unit (ICU) of our hospital, aged 18-60 yr, with the European malnutrition risk screening score in 2002 was ≥ 3, who could not eat orally, were selected.All patients received decompression or aneurysm clipping under general anesthesia.Patients were divided into 2 groups using a random number table method: control group ( n=30) and ultrasound group ( n=31). Nutrient infusion pump was used to infuse standard whole protein formula enteral nutrition continuously through a nasogastric tube.In control group, gastric residual volume, residual traits and bowel sounds were evaluated according to gastric drainage to start or adjust enteral nutrition treatment.In ultrasound group, the antral motility index and gastric residual volume were monitored by the modified antral single section method under ultrasound to start or adjust enteral nutrition treatment.The starting time of enteral nutrition, time to reach the target feeding amount, rate of reaching the target feeding standard within 96 h, interruption of enteral nutrition, duration of hospitalization in ICU, and occurrence of intraperitoneal hypertension, aspiration, diarrhea, gastrointestinal bleeding and new pulmonary infection during enteral nutrition therapy were recorded. Results:Compared with control group, the initiation time of enteral nutrition and time to reach the target feeding amount were significantly shortened, the interruption rate of enteral nutrition was decreased, the rate of reaching the target feeding standard within 96 h was increased, the incidence of aspiration and new pulmonary infection was decreased ( P<0.05), and no significant change was found in the duration of hospitalization in ICU and incidence of intraperitoneal hypertension, diarrhea and upper gastrointestinal bleeding in ultrasound group ( P>0.05). Conclusions:Bedside gastric ultrasound-guided enteral nutrition therapy can improve the therapeutic effect with higher safety in the patients with spontaneous intracerebral hemorrhage.

【Objective】 To investigate the distribution of plasma donors with high titer neutralizing antibodies against human cytomegalovirus (HCMV) in the general plasma donor population. 【Methods】 920 plasma samples of Taibang were tested in April 2014 to investigate the distribution of anti-HCMV neutralizing antibodies. After further testing of mixed plasma, the threshold for screening plasma was determined. From October 2019 to May 2020, neutralizing anti-HCMV in 40 078 plasma samples from 11 plasma stations in Shandong province were screened by the microcytopathic method (modified high-flux neutralization test method). The proportion of neutralizing anti-HCMV enriched in high titer and the distribution in the donor population were analyzed by SPSS 26 and Minitab19 analysis software. 【Results】 Among 920 samples, 73.26%, 0.43%, and 8.69% of them had neutralization titer<1∶15, ≥1∶60 and ≥1∶30, respectively. The neutralization titer of mixed plasma was detected, and 1∶30 was determined as the high titer. The yielding rate of high titer neutralizing anti-HCMV in Shandong was 9.06% (3 633/40 078). The proportion of plasma donors with high-titer neutralizing anti-HCMV in the donation population from plasma stations was 4.95%~13.03% (9.06±2.07) %. The proportion of plasma donors with high-titer neutralizing anti-HCMV by gender was 15.67% (2 185/13 951) in women and 5.54% (1 448/26 127) in men(P<0.05). 【Conclusion】 There was a certain proportion of plasma donors wiht high titer neutralizing anti-HCMV in the population of plasma donors in Shandong, and they can constantly serve neutralizing anti-HCMV to ensure the production of anti-HCMV immunoglobulin preparations.
