Objective:To construct a remote screening network for breast cancer based on automated breast ultrasound (ABUS) and explore the value of ABUS with remote reading for breast cancer screening.Methods:We constructed a remote breast cancer screening network including one remote reading center and 48 image-acquisition centers. We recruited women to participate in breast cancer screening at one of these image-acquisition centers from January 2021 to January 2023. The technicians collected the whole breast images using the ABUS. The images were then sent to the reading center through the PVBUS System and interpreted independently by two radiologists using the Breast Imaging Reporting and Data System (BI-RADS). BI-RADS categories 1 and 2 indicate negative screening results, and women diagnosed with these categories were recommended for annual breast ultrasound screening. BI-RADS categories 3, 4, and 5 indicate positive results. Women with BI-RADS category 3 lesions were recommended for follow-up examinations every 6 months using ABUS or handheld ultrasound, while those with BI-RADS 4 and 5 lesions were suggested to undergo pathological examinations.Results:In our study, we enrolled 10 344 women who completed the ABUS screening and were followed up for more than 12 months. After remote reading, 6 164 women were diagnosed with BI-RADS category 1 and 2 626 woman were within BI-RADS category 2. In contrast, 1 404 women were within BI-RADS category 3, a total of 135 women were within BI-RADS category 4, and 15 women were within BI-RADS category 5. The positive screening rate of ABUS was 15.0% (1 554/10 344). The ABUS with remote reading had a detection rate of 3.7/1 000 (38/10 344) for breast cancer screening, with a sensitivity of 97.4% (38/39) and a specificity of 85.3% (8 789/10 305). Among the 38 breast cancer cases detected, 92.1% (35/38) were invasive carcinomas, and 63.2% (24/38) were stage 0 or Ⅰ breast cancers.Conclusions:Breast cancer screening based on ABUS with remote reading provided an efficient and feasible solution to the problem of unevenly distributed medical resources and medical staff levels in various regions of China, enabling the decentralization of high-quality medical resources and improving the accessibility of high-quality screening services. It has provided an alternative for breast cancer screening in China.

Objective:To discuss the association between occupational acid fog exposure and accelerated biological aging of the workers,and to clarify its related risk factors.Methods:A total of 341 male workers exposed to occupational acid fog and 201 male workers without occupational exposure were selected as the study subjects,and they were divided into exposure group and control group,respectively.The general informations of the subjects in two groups were collected through questionnaires and physical examinations.The levels of red blood cell count(RBC),platelet count(PLT),albumin(ALB),urea(Urea),creatinine(CR),triglycerides(TG),total cholesterol(TC),glycated hemoglobin(HBA1c),and high-sensitivity C-reactive protein(Hs-CRP)in serum of the subjects in two groups were detected.The Klemera-Doubal method(KDM)was used to construct the composite aging measure,KDM-biological age(BA)(KDM-BA).The model parameters were trained using samples from the 2009 China Health and Nutrition Survey(CHNS)Database to calculate the BA acceleration of the subjects in two groups;stratified analysis based on the population characteristics was conducted to analyze the BA of the subjects in two groups with different population characteristics;generalized linear model was used to analyze the factors influencing BA acceleration due to acid fog exposure.Results:The model parameters were trained using samples from the 2009 CHNS Database,including 8 133 cases aged 20-79 years,of which 3 788 were male.The levels of Urea,CR,HBA1c,ALB,and TC,as well as systolic blood pressure(SBP),total working years,sleep duration,and body mass index(BMI)of the subjects between two groups had significant differences(P<0.05).Compared with control group,the BA acceleration of the subjects in exposure group was significantly increased(P<0.05).In entire population and exposure group,the BA acceleration in the smokers was significantly higher than that in the non-smokers(P<0.05).In entire population,control group,and exposure group,the BA accelerations of the subjects in different BMI groups were significantly decreased with the increase of BMI(P<0.05).Compared with control group,the BA acceleration of the subjects in exposure group was significantly increased(P<0.05),including those under 40 years old,with total working years of 4-7 years,Han nationality,unmarried,smokers,and sleep duration 6-7 h,and with overweight.Acid fog exposure,smoking,and BMI were associated with the BA acceleration(β=0.72,95%CI:0.24-1.21;β=0.59,95%CI:0.11-1.06;β=-0.29,95%CI:-0.35—-0.22).Conclusion:Occupational acid fog exposure may accelerate the biological aging in the workers,and acid fog is a risk factor to accelerate the biological aging of the body.

Objective To investigate the effect of hemoperfusion combined with sequential hemodiafiltration on pancreatic islet β cell function,nutritional status and inflammatory response in patients with diabetic nephropathy(DN).Methods One hundred patients with DN admitted to Nanyang Central Hospital from February 2022 to February 2023 were selected as the research subjects.They were divided into the control group and the observation group according to the random number table method,with 50 patients in each group.The patients in the control group were treated with sequential hemodiafil-tration,and the patients in the observation group were treated with sequential hemodiafiltration combined with hemoperfusion.The weight and height of patients in the two groups were measured before treatment and after 6-month treatment to calculate body mass index(BMI).The triceps skinfold(TSF)thickness was measured by using a skinfold caliper.The nutritional status of patients were evaluated by subjective global assessment(SCA)scores.Fasting venous blood was collected from patients in the two groups to measure the levels of fasting insulin(FINS)and fasting plasma glucose(FPG)by radioimmunoassay,and the homeostasis model assessment of insulin resistance(HOMA-IR)and homeostasis model assessment of beta-cell function(HOMA-β)were calculated;the levels of total cholesterol(TC),triglyceride(TG),high-density lipoprotein cholesterol(HDL-C)and low-density lipoprotein cholesterol(LDL-C)were measured by using the fully automatic biochemical analyzer,and the levels of serum C-reactive protein(CRP),tumor necrosis factor-α(TNF-α)and interleukin-6(IL-6)were measured by using the enzyme-linked immunosorbent assay.Results There was no significant difference in HOMA-β,FINS and HOMA-IR of patients between the control group and the observation group before treatment(P＞0.05).FINS and HOMA-IR of patients after treatment were significantly lower than those before treatment,while HOMA-β was significantly higher than that before treatment in the two groups(P＜0.05).After treatment,FINS and HOMA-IR of patients in the observation group were significantly lower than those in the control group,while HOMA-β was significantly higher than that in the control group(P＜0.05).There was no significant difference in BMI,TSF and SGA of patients between the control group and the observation group before treatment(P＞0.05).After treatment,BMI,TSF and SGA of patients in both groups were significantly higher than those before treatment;and BMI,TSF and SGA of patients in the observation group were significantly higher than those in the control group(P＜0.05).There was no significant difference in the levels of TC,TG,LDL-C and HDL-C of patients between the control group and the observation group before treatment(P＞0.05).After treatment,the levels of TC,TG and LDL-C of patients in both groups were significantly lower than those before treatment,while the HDL-C level of patients was significantly higher than that before treatment(P＜0.05).After treatment,the levels of TC,TG and LDL-C of patients in the observation group were significantly lower than those in the control group,while the HDL-C level of patients was significantly higher than that in the control group(P＜0.05).There was no significant difference in the levels of serum CRP,TNF-α and IL-6 of patients between the control group and the observation group before treatment(P＞0.05).After treatment,the levels of serum CRP,TNF-α and IL-6 of patients in both groups were significantly lower than those before treatment;and the levels of serum CRP,TNF-α and IL-6 of patients in the observation group were significantly lower than those in the control group(P＜0.05).Conclusion Sequential hemodiafiltration combined with hemoperfusion can significantly improve pancreatic islet βcell function,nutritional status and lipid metabolism in patients with DN and inhibit inflammatory response.

Objective:To observe any therapeutic effect of combining botulinum toxin type A (BTX-A) with rehabilitation training in treating Parkinson′s disease (PD) patients with striatal foot deformity (SFD).Methods:A total of 68 PD patients with SFD were randomly divided into a control group and a treatment group. Both groups were given routine medication with pramipexole and dopamine receptor agonists and received lower limb rehabilitation training, including passive activity training, strength training and walking training. The treatment group was additionally injected with BTX-A. Sciatic pain was quantified using a visual analogue scale. The Unified Parkinson′s Disease Rating Scale-lower limb motor lower limb motor function (UPDRS-LLM) scale, the Berg balance scale and the modified Barthel index were applied to test all of the participants before the experiment and on the 7th, 14th and 30th day of the treatment.Results:The average scores of the control group on all of measures at were significantly better than those of the control group at the same time points, and by the 14th and 30th day had improved significantly compared with those before treatment.Conclusion:Supplementing rehabilitation training with BTX-A can significantly improve foot deformity and relieve the muscle tension and spastic pain of PD patients with SFD, promoting the motor functioning of their lower limbs, their balance and their performance in the activities of daily living.

Objective:To explore any effect of supplementing low-frequency repeated transcranial magnetic stimulation (rTMS) with intermittent resistance training on muscle tone and the recovery of motor function among persons with Parkinson′s disease (PD).Methods:A total of 104 PD patients were randomly divided into an observation group and a control group, each of 52. Both groups were treated with conventional drugs and low-frequency rTMS, while the observation group was additionally provided with intermittent resistance training for 8 weeks. Before and after the intervention, the motor functioning of both groups was evaluated using unified Parkinson′s disease rating scale-III (UPDRS-III) and the Berg Balance Scale (BBS). Limb muscle tension was quantified using the modified Ashworth scale (MAS). The subjects′ psychological states were quantified using the exercise self-efficacy scale (ESE), and the modified Barthel index (MBI) was applied to evaluate their ability in the activities of daily living. A 3D motion processing system collected and analyzed data describing each subject′s gait kinematics.Results:After the intervention, significantly greater average improvement was observed in all of the outcome measures among the observation group compared with the control group.Conclusion:Combining intermittent resistance training with low-frequency rTMS can significantly reduce muscle tone and improve the motor functioning of PD patients. The combination is more effective than low-frequency rTMS alone.

Objective To investigate the diagnostic value of cervical vagus nerve cross-sectional area(CAS)for Parkinson's disease(PD).Methods Thirty patients with PD admitted to the People's Hospital of Zhengzhou University from October 2019 to October 2022 were selected as PD group,25 patients with multiple system atrophy(MSA)admitted to the People's Hospital of Zhengzhou University during the same period were selected as the MSA group,and 30 healthy individuals who underwent physical examination in the People's Hospital of Zhengzhou University during the same period were selected as healthy control group.Cervical vagus CAS of subjects in the three groups were measured by high-resolution ultrasound,and the difference of CAS of cervical vagus nerve was compared among the three groups.The degree of impairment of autonomic nervous function of subjects in the three groups was evaluated by PD autonomic symptom scale(SCOPA-AUT).The diagnostic value of cervical vagus nerve CAS for PD was analyzed by receiver operating characteristic(ROC)curve.Results The CAS of the right cervical vagus nerve of subjects was significantly larger than that of the left in the healthy control group and PD group(P＜0.05);there was no significant difference in CAS of bilateral cervical vagus nerve of subjects in the MSA group(P＞0.05).The CAS and average CAS of bilateral cervical vagus nerve of subjects in the PD group and MSA group were significantly lower than those in the healthy control group(P＜0.01).The CAS of the right vagus nerve of subjects in the MSA group was significantly lower than that in the PD group(P＜0.05);there was no significant difference in CAS and the average CAS of the left vagus nerve between the MSA group and the PD group(P＞0.05).The total score of SCOPA-AUT and gastrointestinal(GI),cardiovascular(CV),urinary(UR)and sexual(SX)scores of subjects in the PD group and MSA group were significantly higher than those in the healthy control group(P＜0.01).The total score of SCOPA-AUT and UR,SX scores of subjects in the MSA group were significantly higher than those in the PD group(P＜0.05).There was no significant difference in temperature(TH)and pupil(PU)of subjects among the three groups(P＞0.05).Pearson correlation analysis showed that the CAS of cervical vagus nerve of PD patients was not correlated with the total score of SCOPA-AUT and the UR,TH,PU,SX scores(r=-0.143,0.281,0.297,0.265,0.312;P＞0.05).The CAS of cervical vagus nerve of PD patients was negatively correlated with GI and CV scores(r=-0.683,-0.373;P＜0.05).ROC curve analysis showed that the area under the curve of cervical vagus nerve for diagnosing PD was 0.870(95％confidence interval:0.773-0.966,P＜0.05);the critical value was 3.064 mm2,the sensitivity was 96％,and the specificity was 67％.The area under the curve of CAS of cervical vagus nerve in differential diagnosis of PD,MSA was 0.680(95％confidence interval:0.537-0.823,P＜0.05).The sensitivity and specificity for the diagnosis of MSA were 68％and 70％when the CAS of the cervical vagus nerve＜2.709 mm2.Conclusion The CAS of cervical vagal nerve has high clinical diagnostic value for PD,and it provides a new way to improve the diagnosis rate of PD.

Objective:To establish a patient-derived xenograft (PDX) humanized mouse model for hepatoblastoma in children. In addition, compare the biological consistency between successfully modeled PDX tumors and primary tumors in children while comparing and analyzing the influence of PDX model modeling success as a key factor.Methods:A PDX tumor model was constructed from fresh tumor tissue samples from 39 children with hepatoblastoma. The tumor growth time and volume size were recorded in detail. Simultaneously, 39 children’s data were collected for experimental and clinical analysis. The difference in tumorigenesis rate between different parameters was analyzed by χ2 test (categorical variable). Continuous variables with a normal distribution were compared using the t-test. Results:After cell passage and pathological diagnosis, 21 cases of hepatoblastoma PDX models were successfully constructed, with a success rate of 53.8% (21/39). Tumor samples from each generation of successfully modeled PDX models had pathology results that were consistent with those of the corresponding primary tumors. The analysis of the key factors affecting the tumor formation rate of PDX revealed that the metastasis rate was more successful in primary tumors than in liver in situ tumors (7/8 vs. 14/31, P = 0.049). However, there was no significant difference between tumor formation rates and pathological subtypes. According to the PDX tumor formation group comparison between the primary tumor and the metastatic tumor, there was no statistically significant difference between the two groups in terms of tumor formation time and tumor volume. Hematoxylin-eosin staining in hepatoblastoma’s PDX mouse was consistent with the primary tumor. Immunohistochemistry positivity rates of four proteins, namely hepatocyte antigen (Hepatocyte), phosphatidylinositol glycan 3, β-catenin, and alpha-fetoprotein, in primary tumor tissues and PDX mouse models were 100% vs. 100%, 100% vs. 95.24%, 100% vs. 100%, and 95.24% vs. 85.71%, respectively. Conclusion:A PDX mouse model for hepatoblastoma has been successfully established in children. The tumor formation rate is high, with metastatic tumors having a higher tumor formation rate than primary tumors and transplanted tumors retaining the biological characteristics of primary tumors.
