Objective:To compare the aortic remodeling of the Fabulous stent system and standard thoracic aortic endovascular repair (TEVAR) on distal aorta type B aortic dissection (TBAD). Methods:The prospective data collected between Dec 2017 and Oct 2019 from 134 patients with type B aortic dissection (TBAD) who underwent treatment with the "Fabulous" stent system, and retrospective data from 159 TBAD patients receiving standard TEVAR from corresponding multicenter. By using propensity score matching analysis, we compared the prognosis and aortic remodeling outcomes in patients undergoing Fabulous and standard TEVAR treatments during a 1-year postoperative follow-up.Results:In this study, 62 patients in Fabulous group and 62 patients in standard TEVAR were included.There were no significant statistical differences in baseline characteristics between the two groups. In terms of aortic remodeling in bare stent region, Fabulous group had better change trends of diameter of true lumen [10.6 (4.4, 14.5) mm vs. 4.7 (0.9, 10.7) mm, P=0.001] and false lumen [-24.2 (-30.5, -4.9) mm vs. 0.7 (-11.8, 2.3) mm, P<0.001] than those in the standard TEVAR group. The rate of complete false lumen thrombosis was also higher in the Fabulous group (62.9% vs. 37.1%, P=0.042). Conclusion:The Fabulous stent system, when compared to standard TEVAR surgery, demonstrates good aortic remodeling outcomes in the distal aorta.

Objective To develop a nomogram model based on the clinical features and the radiomics texture analysis of multimodal magnetic resonance imaging(MRI),so as to predict the tumor response in patients with advanced hepatocellular carcinoma(HCC)3 months after receiving transcatheter arterial chemoembolization(TACE).Methods A total of 105 patients with advanced HCC,whose diagnosis was pathologically-confirmed at the Suzhou Municipal Ninth People's Hospital between January 2017 and December 2021,were enrolled in this study.The patients were randomly divided into training group(n=63)and verification group(n=42).Before chemotherapy,T1WI,T2WI,dynamic contrast-enhanced(DCE)scan,and diffusion-weighted imaging(DWI)were performed by using a 3.0T MRI scanner.A.K.software was used to extract the texture.Three months after chemotherapy,according to the modified Response Evaluation Criteria in Solid Tumors(mRECIST)the patients were divided into response group(n=63)and non-response group(n=42).Results Compared with the response group,in the non-response group the percentage of Child-Pugh grade B and BCLC stage C was obviously higher and the serum alpha fetoprotein(AFP)level was remarkably elevated(P＜0.05).A.K.software extracted 396 MRI texture features,and LASSO regression analysis screened out 6 optimal predictors.The radiation score(Rad-score)was calculated by ROC.The AUC of Rad-score for predicting tumor non-response after TACE by ROC in the training group and verification group were 0.842 and 0.803 respectively.Multivariate logistic regression model analysis showed that AFP≥50 ng/mL(OR=1.568,95%CI=1.234-1.902,P=0.003),Child-Pugh grade B(OR=1.754,95%CI=1.326-2.021,P=0.001),BCLC stage C(OR=1.847,95%CI=1.412-2.232,P=0.001)and Rad-score(OR=2.023,95%CI=1.569-2.457,P＜0.001)were the independent risk factors for tumor non-response.Clinico-radiomics combination had the highest AUC value for predicting tumor non-response.The correction curve showed that the nomogram model had a good agreement.Conclusion The quantitative score of radiomics texture analysis of multimodal MRI has a certain value in predicting tumor non-response in advanced HCC patients 3 months after TACE,and the nomogram model,which is constructed if combined with clinical factors,carries good practical potential.(J Intervent Radiol,2024,32:63-68)

Objective:To analyze the mediating effects of emotional changes in self-management interventions on the relationship between behavioral management and quality of life in elderly patients with type 2 diabetes and therefore to provide a reference for improving the emotional status of elderly diabetes patients and future community-based self-management interventions.Methods:From 2016 to 2020, a total of 69 self-management groups were formed in Hangzhou, each consisting of 10-15 patients with type 2 diabetes.Based on the construction of a medical consortium and family doctors signing up to provide services, intervention teams were established to conduct a series of group self-management activities for each group.Surveys via questionnaires were conducted before and after the intervention, as well as 6 months after the intervention, to collect patient data on demographics, disease status, emotions, quality of life, and self-management behaviors.The intervention effects were evaluated, and the correlations between emotional changes, self-management behaviors, and changes in quality of life were analyzed.Bootstrap analysis was used to test the mediating effects.Results:A total of 707 elderly diabetes patients were included.There were statistically significant differences in the scores of the Self-Rating Anxiety Scale(SAS), the Self-Rating Depression Scale(SDS), physical functioning, role-physical, bodily pain, general health, vitality, social functioning, role-emotional, mental health, physical component summary, mental component summary, the dietary control dimension of the type 2 diabetes self-care scale(2-DSCS), regular exercise, medication adherence, blood glucose monitoring, foot care, the dimension of prevention and management of hyperglycemia and hypoglycemia, and the total score of 2-DSCS( P<0.05 for all).Compared with pre-intervention, changes in SAS, SDS, physical component summary and mental component summary scores were all correlated with each dimension of 2-DSCS right after intervention and 6 months after intervention( r=-0.336-0.333, P<0.05), with the exception of changes in the blood glucose monitoring dimension score and changes in the emotional status score.The direct effect of self-management behavior on the quality of life in elderly patients with type 2 diabetes was 0.159, and the indirect effect through emotions was 0.229, with the mediating effect accounting for 59.02% of the total effect. Conclusions:Community-based group self-management activities can effectively improve the emotions and management behaviors of elderly diabetes patients and enhance their quality of life, Emotional changes play a certain mediating role between self-management behaviors and improvement in quality of life.

Objective: To understand the situation of blood pressure control and its influencing factors in elderly patients with hypertension in Hangzhou, and to provide basis for the management of elderly patients with hypertension in community. Methods: The subjects of this study were hypertension patients aged 60 years and over in Hangzhou community health management of basic public health services. Demographic data and life behaviors were collected by a questionnaire survey, physical examination and laboratory tests were carried out. The multivariate logistic regression model was used to analyze the influencing factors for blood pressure control in elderly patients with hypertension. Results: A total of 109 583 people were investigated, with 50 500（46.08%） males and 59 083（53.92%） females. The control rate was 47.70% ( 52 273/109 583 ). After adjusted for age and gender, regular medication ( OR=0.874, 95%CI: 0.838-0.912 ) was the protective factor, obesity ( OR=1.291, 95%CI: 1.260-1.324 ), abnormal fasting plasma glucose ( OR=1.218-1.344, 95%CI: 1.178-1.410 ), the number of unhealthy lifestyles ( OR=1.271-1.292, 95%CI: 1.231-1.344 ), the items of dyslipidemia ( OR=1.047-1.253, 95%CI: 1.017-1.311 ), and the number of cardiovascular risk factors above ( OR=1.254-2.109, 95%CI：1.175-2.281 ) were the risk factors for blood pressure control in elderly patients with hypertension. Conclusions The control rate of elderly patients with hypertension in Hangzhou is 47.70%, which is associated with irregular medication, unhealthy lifestyle, obesity, dyslipidemia, abnormal fasting plasma glucose and clustering of these factors.

Objective:To observe effect of Jingulian capsule on the proliferation of human breast cancer MDA-MB-231 cells and investigate its action mechanism against triple negative breast cancer （TNBC）. Method:The ingredients of Jingulian capsule were identified by ultra-performance liquid chromatography-tandem mass spectrometry（UPLC-MS/MS）. The inhibitory effect of Jingulian capsule at different doses （0.125，0.25，0.5，1，and 2 g·L^-1） against the proliferation of MDA-MB-231 cells were detected by methyl thiazolyl tetrazolium （MTT） assay. After treatment for 24 h， the morphological changes in nuclear apoptosis of MDA-MB-231 cells were detected by Hoechst 33258 staining. The effect of different concentrations of Jingulian capsule on the apoptosis and cycle of MDA-MB-231 cells after different treatment time were determined by flow cytometry. The protein expression levels of Poly-ADP-ribose polymeras （PARP）， proto-oncogene c-Myc， cyclin B₁， and phosphorylated extracellular signal-regulated kinase （p-ERK） in each group were assayed by Western blot. Result:A total of 113 compounds in Jingulian capsule were identified by UPLC-MS/MS. As revealed by MTT assay，compared with blank group，Jingulian capsule （0.125，0.25，0.5，1，2 g·L^-1） significantly inhibited viability of MDA-MB-231 cells （P<0.01）， with the half maximal inhibitory concentration （ IC₅₀） of（0.13±0.02）g·L^-1. According to flow cytometry，compared with the blank group，Jingulian capsule at 1 g·L^-1 significantly induced the apoptosis of MDA-MB-231 cells （P<0.05）and Jingulian capsule at 0.5， 1 g·L^-1 obviously increased the number of MDA-MB-231 cells in S phase （P<0.05，P<0.01）. The results of Western blotting demonstrated that the protein expression levels of PARP，c-Myc，and cyclin B₁ in 0.5， 1 g·L^-1 Jingulian capsule groups were remarkably down-regulated as compared with those in the blank group（P<0.01）， and the protein expression level of p-ERK in 1 g·L^-1 Jingulian capsule group was also down-regulated （P<0.01）. Conclusion:Jingulian capsule is able to inhibit the proliferation of MDA-MB-231 cells，induce S phase cell cycle arrest， and promote their apoptosis， which may be related to the inactivation of the MAPK signaling pathway.

【Objective】 To analyze the quality level of the laboratory pre-analytical phase, so as to take effective quality improvement interventions to further standardize the operation and provide basis for ensuring the quality of blood testing. 【Methods】 Pre-analytical phase quality indicators of blood screening laboratory in Shanghai Blood Center were established, and those had serious impact on blood safety were defined as the sentinel indicators. The pre-analytical quality level of our laboratory from 2018 to 2020 was statistically analyzed in terms of four parts including sample collection, preservation and submission, centrifugation and quality inspection, which contained 17 indicators. 【Results】 Eleven sentinel indicators were established, and the order of peak value from high to low in three years was as follows: " label omission" rated at 0.000 62% (2020), " label error" 0.000 57% (2018), " inappropriate storage of samples before detection" 0.007 39 (2018), " unqualified application form for sample detection" 0.007 39 (2018). The causes were analyzed and relevant measures were taken. Six monitoring indicators were established, and the order of peak value from high to low in three years was as follows: " insufficient sample" rated at 0.002 59% (year 2018), " hemolysis" 0.002 80% (year 2020), " pale color of blood supernatant (diluted)" 0.000 86 (2018), " automatic sampling interfered by blood clot" 0.027 02% (2018). 【Conclusion】 The quality indexes of pre-analytical phase in our laboratory have reached the level of domestic and international clinical laboratories. The establishment of pre-analytical quality indicators and sentinel indicators, with effective analysis and application, can fully record and monitor the quality of each link before laboratory testing, which is helpful to timely identify risks, detect deviations, and quickly implement corrective and preventive measures, thus further ensure the safety of clinical blood use.

Chemical stimulation of the kidney increases sympathetic activity and blood pressure in rats. The hypothalamic paraventricular nucleus (PVN) is important in mediating the excitatory renal reflex (ERR). In this study, we examined the role of molecular signaling in the PVN in mediating the capsaicin-induced ERR and sympathetic activation. Bilateral PVN microinjections were performed in rats under anesthesia. The ERR was elicited by infusion of capsaicin into the cortico-medullary border of the right kidney. The reflex was evaluated as the capsaicin-induced changes in left renal sympathetic nerve activity and mean arterial pressure. Blockade of angiotensin type 1 receptors with losartan or inhibition of angiotensin-converting enzyme with captopril in the PVN abolished the capsaicin-induced ERR. Renal infusion of capsaicin significantly increased NAD(P)H oxidase activity and superoxide anion production in the PVN, which were prevented by ipsilateral renal denervation or microinjection of losartan into the PVN. Furthermore, either scavenging of superoxide anions or inhibition of NAD(P)H oxidase in the PVN abolished the capsaicin-induced ERR. We conclude that the ERR induced by renal infusion of capsaicin is mediated by angiotensin type 1 receptor-related NAD(P)H oxidase activation and superoxide anion production within the PVN.

OBJECTIVE: To investigate the effect of continuous adductor block on pain control after bilateral knee joint Ⅰ stage replacement. METHODS: A retrospective analysis was made of the data of 24 patients with bilateral knee joint I stage replacement who were treated in our hospital from January 2018 to January 2019, and who underwent continuous adductor block analgesia. There were 6 males and 18 females, aged 60 to 72 (65.05±5.82) years old. The patients underwent continuous block of adductor canal with patient-controlled analgesia system. At 4, 6, 12, 24, 36 and 48 hours after operation, visual analogue score(VAS) of resting state and passive motion state was performed;the knee joint activity was followed up for 1 week, 1, 3 and 6 months after operation;the knee joint function was scored at 6 months after operation, using the knee joint scoring standard of American Special Surgery Hospital(HSS);adverse reactions and complications were recorded. RESULTS: The VAS scores under resting state and passive motion state at each time point were less than 3 points in patients with continuous adductor block. The patients had better postoperative exercise of knee joint activity. The score of HSS was excellent in 20 cases, good in 2 cases, fair in 1 case and poor in 1 case. There were only 4 cases of nausea and vomiting, none of them had serious adverse reactions and complications such as bradycardia and deep vein thrombosis. CONCLUSION Continuous adductor block has a significant effect on pain control and less adverse reactions after bilateral knee jointⅠ -stage replacement.

Objective:To compare the curative effect of hematoma removal and minimally invasive puncture drainage in hypertensive intracerebral hemorrhage (HICH) under neuroendoscope.Methods:The clinical data of 118 patients with HICH admitted to our hospital from February 2017 to November 2019 were retrospectively analyzed. According to the different surgical methods, the patients were divided into group A ( n=59, minimally invasive puncture and drainage) and group B ( n=59, neuroendoscopic hematoma removal). The perioperative indexes, complications and neurological function indexes [neuron specific enolase (NSE), neurotrophic factor (NGF), substance P (SP)], inflammatory factor index [interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α)] and related scale scores [National Institutes of Health Stroke Scale (NIHSS), modified Barthel Index (mBI)] were compared between the two groups. Results:The operation time, cerebrospinal fluid recovery time, hematoma removal time and hospitalization time of group B were shorter than those of group A ( P<0.05). On the 7th day after operation, the NSE, SP, IL-6, TNF-α in the two groups were decreased, and the levels of NSE, SP, IL-6 and TNF-α in group B were lower than those in group A ( P<0.05); on the 7th day after operation, the levels of NGF in two groups were increased, and those in group B were higher than those in group A ( P<0.05). 6 months after operation, the NIHSS decreased and mBI increased in both groups ( P<0.05), and NIHSS in group B was lower than that in group A, but mBI was higher than that in group A ( P<0.05). There was no difference in the incidence of complications between the two groups ( P>0.05). Conclusions:Compared with minimally invasive puncture and drainage, neuroendoscope hematoma removal for HICH patients can effectively improve perioperative indicators, reduce neurological damage and body inflammatory stimulation, and improve the self-care ability of patients, which is safe and reliable.

Objective:To evaluate the effect of self-management model of community diabetes patients under the guidance of general practitioners.Methods:A total of 22 communities in Hangzhou were selected as intervention pilot from 2016 to 2017, and 10-15 diabetic patients were recruited to form a self-management team in each community. Relying on the construction of medical alliance and there sources of contracted service of family doctors, intervention teams were set up to conduct regular, personalized and continuous self-management interventions on patients. Intervention continued for 4-6 months. Before, after and 6 months after the intervention, the basic information of patients, knowledge of diabetes, faith in managing disease, self-management behavior, self-management ability of patients, and quality of life were collected through questionnaire survey, body mass index (BMI), 2-hour postprandial blood glucose and glycosylated hemoglobin were detected uniformly, and statistical analysis was conducted.Results:A total of 292 patients were involved in the self-management group, the average age was (66.38±7.90) years old, most of them were female (64.73%). Six months after the intervention, the awareness rate of basic knowledge, risk factors and prevention and treatment knowledge about diabetes in patients (68.64%, 78.75%, 63.41%) were significantly higher than those before the intervention (28.08%, 48.29%, 39.38%), the proportion of patients with reasonable diet, moderate exercise, active problem-solving, management plan making and action according to the plan increased (from 65.41%, 28.76%, 39.04%, 31.85%, 27.74% to 86.76%, 60.28%, 65.16%, 78.05%, 73.17%)(all P<0.05).In terms of time effect, the scores of physical functioning, role-physical, bodily pain, general health, vitality, social functioning, role-emotional and mental health in SF-36 after intervention and 6 months after intervention were all increased step by step (all P<0.05). Before the intervention, BMI, 2-hour postprandial blood glucose and glycosylated hemoglobin were (24.20±3.11) kg/m 2, (9.29±2.23) mmol/L, (6.81±1.01)% respectively. After the intervention, the three indexes all showed a downward trend, which were (22.89±2.98) kg/m 2, (8.81±1.61) mmol/L, (6.57±0.76)% respectively ( F=14.832, 6.828, 9.667; all P<0.05). Conclusion:Under the guidance of general practitioners, the self-management model of community diabetes patients can effectively improve the level of recognition, belief and behavior of patients, improve their self-management ability and quality of life, and improve BMI and blood glucose control level.
