Objective To explore the relationship between the expression levels of adenosine triphosphate binds to the box transporter C4(ABCC4)and microRNA-125b-5p(miR-125b-5p)and survival 3 years after surgery in prostate cancer(PCa)tissue.Methods A total of 60 patients with PCa diagnosed in Huanghua People's Hospital from November 2017 to February 2020 were selected,and PCa tissues(PCa group)and pa-racancer tissues(control group)were collected intraoperatively.The expression levels of ABCC4 mRNA,miR-125b-5p and ABCC4 in the samples were detected;the patients were followed up for 3 years.The correlation between the expression levels of ABCC4 mRNA and miR-125b-5p in PCa tissues,their relationship with clini-copathological features and prognosis,and the factors affecting the prognosis of PCa patients,the predictive value of both for 3-year survival of patients were analyzed.Results The expression level and positive rate of ABCC4 mRNA in PCa group were higher than those in control group,and the expression level of miR-125b-5p was lower than that in control group,and the differences were statistically significant(P＜0.05).The expres-sion level of ABCC4 mRNA and miR-125b-5p in PCa tissue was negatively correlated(P＜0.05).The expres-sion level of ABCC4 mRNA and miR-125b-5p in PCa tissue was related to tumor stage,serum prostate specific antigen,Gleason score and tumor metastasis(P＜0.05).The 3-year cumulative survival rate of patients in the ABCC4 mRNA high expression group and the miR-125b-5p low expression group was lower than that in the ABCC4 mRNA low expression group and the miR-125b-5p high expression group,respectively,and the differ-ences were statistically significant(P＜0.05).The expression level of ABCC4 mRNA in the PCa tissue in death group was higher than that in survival group,and the expression level of miR-125b-5p was lower than that in survival group,and the differences were statistically significant(P＜0.05).High expression of ABCC4 mRNA and low expression of miR-125b-5p were independent risk factors for poor prognosis in PCa patients(P＜0.05).Compared to the area under the curve(AUC)predicted by ABCC4 mRNA and miR-125b-5p alone for 3-year survival in PCa patients,the combined prediction of the two had a higher AUC(P＜0.05).Conclu-sion ABCC4 is highly expressed and miR-125b-5p is low expressed in PCa patients'cancer tissues,and the combination of the two has a high predictive power for 3-year survival in PCa patients.

The important role of TDP-43 proteinopathy in Alzheimer's disease (AD) has been gradually revealed. High proportion of AD patients have TDP-43 proteinopathy on their postmortem diagnosis. Patients with TDP-43 proteinopathy show more sever hippocampal atrophy and cognitive dysfunction, suggesting that TDP-43 proteinopathy can serve as an important target in AD diagnosis and treatment. Evaluation of TDP-43 proteinopathy in vivo would hold great promise in AD diagnosis, drug development and treatment. In this review, we describe the pathological characteristics of TDP-43 proteinopathy in AD, and summarize the recent progress of TDP-43 proteinopathy in the diagnosis and treatment of AD.

Objective:To analyze the effect of different lithotomy positions on hemodynamics in patients undergoing laparoscopic total hysterectomy.Methods:A total of 50 patients who underwent laparoscopic total hysterectomy at Zhoushan Women and Children's Hospital between January 2020 and June 2021 were included in this study. The patients were randomly divided into a control group and an observation group using a random number table method, with 25 patients in each group. The control group underwent conventional lithotomy position total laparoscopic hysterectomy, while the observation group underwent high and low lithotomy position total laparoscopic hysterectomy. The general surgical indicators, respiratory function indicators, blood gas analysis indicators, hemodynamic levels, incidence of complications, and clinical efficacy were compared between the two groups.Results:The general surgical indicators and airway peak pressure indicators in the observation group were significantly lower than those in the control group (both P < 0.05). There was no statistically significant difference in partial pressure of end-tidal carbon dioxide (PCO 2) and arterial carbon dioxide partial pressure (PaCO 2) between the two groups (both P < 0.05). At 15 minutes after pneumoperitoneum, the PaCO 2 level increased in each group, and the PaCO 2 level in the observation group was significantly higher than that in the control group (all P < 0.05). At the same time, the HCO 3- level decreased in each group, and the HCO 3- level in the observation group was significantly lower than that in the control group (all P < 0.05). At 5 minutes before recovery of body position, heart rate, systolic blood pressure, and diastolic blood pressure in the control group were (76.52 ± 8.61) beats/minute, (113.52 ± 5.36) mmHg (1 mmHg = 0.133 kPa), and (86.91 ± 4.21) mmHg, respectively. At 5 minutes after recovery of body position, heart rate, systolic blood pressure, and diastolic blood pressure in the control group were (89.52 ± 8.61) beats/minute, (106.85 ± 5.63) mmHg, and (80.96 ± 3.65) mmHg, respectively. At 5 minutes before recovery of body position, heart rate, systolic blood pressure, and diastolic blood pressure in the observation group were (76.36 ± 8.61) beats/minute, (112.79 ± 5.28) mmHg, and (86.89 ± 4.54) mmHg. At 5 minutes after recovery of body position, heart rate, systolic blood pressure, and diastolic blood pressure in the observation group were (75.63 ± 6.86) beats/minute, (111.99 ± 5.51) mmHg, and (85.06 ± 3.21) mmHg, respectively. At 5 minutes after recovery of body position, heart rate in the control group was increased and that in the observation group was decreased compared with heart rate measured at 5 minutes before recovery of body position. At 5 minutes after recovery of body position, heart rate in the observation group was significantly lower than that in the control group. Diastolic blood pressure and systolic blood pressure decreased in each group, and the amplitudes of reductions in diastolic blood pressure and systolic blood pressure in the observation group were significantly lower than those in the control group. ( t = 6.04, 3.26, 4.22, all P < 0.05). There was no statistically significant difference in incidence of adverse reactions between the two groups ( P > 0.05). The overall response rate in the observation group was significantly higher than that in the control group ( P < 0.05). Conclusion:Compared with conventional lithotomy position total laparoscopic hysteretsotomy, high and low lithotomy position total laparoscopic hysterectomy takes a shorter duration for total laparoscopic hysterectomy, leads to a shorter length of hospital stay, results in less blood loss, causes fewer postoperative infections, and results in more stable hemodynamics and a lower incidence of complications.

BACKGROUND: Juvenile amyotrophic lateral sclerosis (JALS) is an uncommon form of amyotrophic lateral sclerosis whose age at onset (AAO) is defined as prior to 25 years. FUS mutations are the most common cause of JALS. SPTLC1 was recently identified as a disease-causative gene for JALS, which has rarely been reported in Asian populations. Little is known regarding the difference in clinical features between JALS patients carrying FUS and SPTLC1 mutations. This study aimed to screen mutations in JALS patients and to compare the clinical features between JALS patients with FUS and SPTLC1 mutations. METHODS: Sixteen JALS patients were enrolled, including three newly recruited patients between July 2015 and August 2018 from the Second Affiliated Hospital, Zhejiang University School of Medicine. Mutations were screened by whole-exome sequencing. In addition, clinical features such as AAO, onset site and disease duration were extracted and compared between JALS patients carrying FUS and SPTLC1 mutations through a literature review. RESULTS: A novel and de novo SPTLC1 mutation (c.58G>A, p.A20T) was identified in a sporadic patient. Among 16 JALS patients, 7/16 carried FUS mutations and 5/16 carried respective SPTLC1 , SETX , NEFH , DCTN1 , and TARDBP mutations. Compared with FUS mutation patients, those with SPTLC1 mutations had an earlier AAO (7.9 ± 4.6 years vs. 18.1 ± 3.9 years, P  < 0.01), much longer disease duration (512.0 [416.7-607.3] months vs. 33.4 [21.6-45.1] months, P  < 0.01), and no onset of bulbar. CONCLUSION Our findings expand the genetic and phenotypic spectrum of JALS and help to better understand the genotype-phenotype correlation of JALS.

For the detection and identification of abnormal nodular tissues on the body surface, a microwave sensor structure loaded with a spiral resonator is proposed in this paper, a sensor simulation model is established using HFSS software, the structural parameters are optimized, and the actual sensor is fabricated. The S21 parameters of the tissue were obtained when nodules appeared by simulation, and the characteristic relationship between the difference of S21 parameters with position was analyzed and tested experimentally. The results showed that when nodules were present in normal tissues, the curve of S21 parameter difference with position change had obvious inverted bimodal characteristics, and the extreme value of S21 parameter difference appeared when the sensor was directly above the nodules, which was easy to identify the position of nodules. It provides an objective detection tool for the identification of abnormal nodular tissues on the body surface.

Studies have shown that rosacea is related to inflammatory factors, neurovascular function, micro-ecological environment and other factors. The Janus kinase (JAK) -signal transducer and activator of transcription (STAT) signaling pathway involves a variety of inflammatory cytokines, and plays an important role in cell proliferation, differentiation, apoptosis, angiogenesis and immune regulation. This review summarizes the JAK-STAT signaling pathway and explores its potential role in rosacea.

Objective:To summarize and analyze the clinical data of Chinese patients with colony-stimulating factor 1 receptor (CSF1R)-related leukoencephalopathy, and clarify the phenotypic and genetic characteristics of Chinese patients.Methods:Medical history of patients with CSF1R-related leukoencephalopathy diagnosed from April 1, 2018 to January 31, 2021 in the department of neurology of 22 hospitals in China was collected, and scores of Mini-Mental State Examination (MMSE), Montreal Cognitive Assessment Scale (MoCA), magnetic resonance severity scale were evaluated. Group comparison was performed between male and female patients.Results:A total of 62 patients were included, and the male-female ratio was 1∶1.95. The age of onset was (40.35±8.42) years. Cognitive impairment (82.3%, 51/62) and motor symptoms (77.4%,48/62) were the most common symptoms. The MMSE and MoCA scores were 18.79±7.16 and 13.96±7.23, respectively, and the scores of two scales in male patients (22.06±5.31 and 18.08±5.60) were significantly higher than those in females (15.53±7.41 , t=2.954, P=0.006; 10.15±6.26, t=3.328 , P=0.003). The most common radiographic feature was bilateral asymmetric white matter changes (100.0%), and the magnetic resonance imaging severity scale score was 27.42±11.40, while the white matter lesion score of females (22.94±8.39) was significantly higher than that of males (17.62±8.74 , t=-2.221, P<0.05). A total of 36 CSF1R gene mutations were found in this study, among which c.2381T>C/p.I794T was the hotspot mutation that carried by 17.9% (10/56) of the probands. Conclusions:The core phenotypic characteristics of CSF1R-related leukoencephalopathy in China are progressive motor and cognitive impairment, with bilateral asymmetrical white matter changes. In addition, there exist gender differences clinically, with severer cognitive impairment and imaging changes in female patients. Thirty-six CSF1R gene mutations were found in this study, and c.2381T>C/p. I794T was the hotspot mutation.

Brachytherapy plays an important role in radical radiotherapy of cervical cancer. At present, most hospitals in China use high-dose-ate brachytherapy, which irradiatevolume by simulating line source with a single approximate point source. Therefore, the dwell positions and dwell times can be optimized appropriately. However, due to various reasons, the initial state of the optimization plan must start from the standard loading pattern, and ensure that the optimized plan basically maintains the pear-shaped dose distribution. This paper introduces the standard loading pattern of intracavitary brachytherapy and intracavitary combined interstitial brachytherapy for cervical cancer through literature review, and expounds the planning optimization model and the constraints in the optimization process, to provide important reference for the planning of brachytherapy for cervical cancer.

Objective:To investigate the risk factors for bleeding at femoral artery puncture site after neurointervention and to compare the effectiveness of different hemostatic methods.Methods:Patients underwent whole brain angiography and cerebrovascular interventional therapy in the Department of Neurology, the Fourth Affiliated Hospital of Nanjing Medical University from November 2017 to May 2019 were collected retrospectively. According to the situation of femoral artery puncture site after sheath removal, the patients were divided into bleeding group and non-bleeding group. The baseline data, laboratory tests, and intraoperative data were compared between the two groups. Multivariate logistic regression analysis was used to determine the independent risk factors for bleeding at femoral artery puncture site. The hemostasis time of different diameter vascular sheath (5 F, 6 F or 8 F) under different hemostasis schemes (manual compression, vascular stapler, and vascular occluder) were analyzed. Results:A total of 721 patients performed neurointervention were included, including 264 interventional therapy and 457 whole brain angiography. Forty-six patients (6.4%) had bleeding at the puncture site after procedure, including 25 patients (3.5%) with oozing of blood, 18 (2.5%) with hematoma, and 3 (0.4%) with pseudoaneurysm. Multivariate logistic regression analysis showed that intraoperative systolic blood pressure (odds ratio [ OR] 1.025, 95% confidence interval [ CI] 1.004-1.047; P=0.021), number of punctures ( OR 1.075, 95% CI 1.053-1.097; P<0.001), heparin dose ( OR 2.142, 95% CI 1.638-3.471; P<0.001), operation time ( OR 3.727, 95% CI 2.025-6.860; P<0.001) and manual compression ( OR 3.449, 95% CI 1.230-9.669; P=0.019) were the independent risk factors for bleeding at the puncture site after operation. No matter which hemostasis scheme was used, the hemostasis time would be prolonged with the increase of the diameter of the vascular sheath, but there was a significant statistical difference in hemostasis time of different vascular sheath diameter groups only when using manual compression ( P<0.05). In addition, no matter what the diameter of vascular sheath was, the hemostasis time of using vascular stapler and vascular occluder was significantly shorter than that of manual compression, and there was statistical significance between the groups ( P<0.05). Conclusion:Reducing the number of punctures, shortening the operation time, and using different hemostatic methods for different diameter vascular sheaths can reduce the incidence of bleeding at the femoral artery puncture site.

Objective:To discuss the feasibility of using online and offline combined multidisciplinary team (MDT) diagnosis-treatment mode in cancers diagnosis and treatment by comparing the comprehensive diagnosis and treatment plans formulated by online and offline MDT diagnosis-treatment mode.Methods:A total of 168 esophageal cancer patients collected from March 17, 2020 to May 17, 2020 were took as the research objects in Shandong Cancer Hospital and Institute, through whom the consistency of the comprehensive diagnosis and treatment plans formulated by online and offline MDT diagnosis-treatment mode was evaluated. The clinical characteristics of patients with changed comprehensive diagnosis and treatment plans, such as age, Karnofsky performance status (KPS) score, whether combined with basic diseases, whether received anti-tumor treatment before and tumor location were analyzed, so as to explore the mechanism to improve the efficiency on the basis of quality assurance.Results:The results showed that 86.3% (145/168) of the comprehensive diagnosis and treatment plans obtained by offline MDT diagnosis-treatment mode were consistent with online diagnosis-treatment MDT mode. Cases with inconsistent comprehensive diagnosis and treatment plans were characterized by elderly (> 69 years) ( χ2=4.250, P=0.039), KPS score≥80 ( χ2=15.520, P<0.001) and combined with underlying disease ( χ2=7.135, P=0.008). Through further analysis, the changed cases were also characterized as with inadequate auxiliary examination or complex in imaging. Conclusion:The online and offline combined MDT diagnosis-treatment mode is feasible. For the patients characterized of elderly (> 69 years old), KPS score ≥80, combined with underlying diseases, with incomplete auxiliary examination or complex in imaging, the offline MDT diagnosis-treatment mode should be adopted or supplemented.
