Objective To investigate the efficacy and safety of transcatheter arterial chemoembolization(TACE)for the treatment of locally recurrent breast cancer.Methods The clinical data of 57 patients with locally recurrent breast cancer from January 2018 to December 2020 were retrospectively analyzed.Twenty-four patients(group A)received TACE using adriamycin 12 mg/m2 and paclitaxel 45 mg/m2,which was accomplished by local perfusion into the tumor target blood vessels with microcatheter catheterization,the embolization material was Embosphere microspheres,and the embolization endpoint was occlusion of the main stem of the target vessel.Other 33 patients who received systemic chemotherapy using adriamycin 40 mg/m2 and paclitaxel 135 mg/m2 in the same period were collected as group B.The 6-month disease control rate(DCR),progression-free survival(PFS)and overall survival(OS)were compared between the two groups.Results Successful TACE was accomplished in all the 24 patients of group A,with a technical success rate of 100％.In group A,the 6-month DCR was 87.50％,the median PFS was 12 months,and the median OS was 22 months.In group B,the 6-month DCR was 63.63％,the median PFS was 9 months,and the median OS was 20 months.The differences in the 6-month DCR and the median PFS between the two groups were statistically significant(P=0.04 and P=0.03 respectively),while no statistically significant difference in the median OS existed between the two groups(P=0.21).The incidence of post-embolization syndrome in group A was 75％(18/24),the clinical symptoms included chest wall pain and mild fever,which disappeared 3 days after symptomatic treatment such as pain-relief and antipyretic medication,and no TACE-related serious complications such as target vessel injury,ectopic embolization of embolization materials or chest wall necrosis occurred in all patients.All patients were followed up for a mean period of(19.47±4.96)months(range of 8-24 months)Conclusion For the treatment of locally recurrent breast cancer,TACE is superior to systemic chemotherapy in short-term efficacy.TACE carries no intervention-related serious complications.However,more studies need to be conducted before its long-term efficacy and safety can be clarified.(J Intervent Radiol,2024,33:280-284)

OBJECTIVE To investigate the effects of the peroxisome proliferator-activated receptors δ （PPARδ） agonist GW501516 on the injury of pulmonary artery endothelial cells （PAECs） induced by hypoxia and its mechanism. METHODS The cytotoxic effects of GW501516 were observed by detecting the relative survival rate of PAECs； the protein expression of PPARδ was determined by Western blot assay. The cellular model of PAECs injury was established under hypoxic conditions； using antioxidant N-acetylcysteine （NAC） as positive control， the effects of GW501516 on cell injury and reactive oxygen species （ROS） production were investigated by detecting cell apoptotic rate， cell viability， lactate dehydrogenase （LDH） activity and ROS levels. Using nuclear factor erythroid 2-related factor 2（Nrf2） activator dimethyl fumarate （DMF） as positive control， PAECs were incubated with GW501516 and/or Nrf2 inhibitor ML385 under hypoxic conditions； the mechanism of GW501516 on PAECs injury induced by hypoxia was investigated by detecting cell injury （cell apoptosis， cell viability， LDH activity）， the levels of superoxide dismutase （SOD）， glutathione peroxidase （GPx）， catalase （CAT）， malondialdehyde （MDA） and ROS， the expressions of Nrf2， heme oxygenase-1 （HO-1） and cleaved-caspase-3 （C-caspase-3） protein. RESULTS The results demonstrated that hypoxia inhibited the protein expression of PPARδ （P＜0.05）， while GW501516 promoted the protein expression of PPARδ in hypoxia- exposed PAECs without obvious cytotoxic effects. GW501516 inhibited the apoptosis of PAECs， improved cell viability， and reduced LDH activity and ROS levels. GW501516 could up-regulate the protein expression of HO-1 in PAECs and the levels of SOD， GPx and CAT， while down-regulated the levels of MDA and ROS by activating the Nrf2 pathway （P＜0.05）； but Nrf2 inhibitor ML385 could reverse the above effects of GW501516 （P＜0.05）. GW501516 exerted similar effects to Nrf2 activator DMF in down-regulating the expression of C-caspase-3 and inhibiting the injury of PAECs under conditions of hypoxia （P＜0.05）. Moreover， Nrf2 inhibitor ML385 reversed the 163.com inhibition effects of GW501516 on PAECs injury （P＜0.05）. CONCLUSIONS GW501516 can relieve the hypoxia-induced injury of PAECs via the inhibition of oxidative stress， the mechanism of which may be associated with activating Nrf2.

Objective To investigate the effect of green laser anatomical vaporization on patients with benign prostatic hyperplasia(BPH)and type 2 diabetes mellitus(T2DM),as well as its impact on inflammatory factors,quality of life,and urethral stricture.Methods A total of 120 patients with BPH and T2DM who were treated at the First Affiliated Hospital of Xinxiang Medical University from March 2021 to August 2022 were selected as the research subjects.The patients were divided into a control group and an observation group according to the surgical approach,with 60 cases in each group.Patients in the control group underwent green laser selective photovaporization,while patients in the observation group were treated with green laser anatomical vaporization.The intraoperative and postoperative recovery indicators such as operation time,intraoperative blood loss,prostate resection quality,catheter indwelling time,bladder irrigation time,and hospitalization time of patients between the two groups were compared.The serum levels of interleukin-6(IL-6)and tumor necrosis factor-α(TNF-α)were detected by using enzyme-linked immunosorbent assay,and the serum levels of malondialdehyde(MDA)and lipid peroxide(LPO)were detected by using immunofluorescence assay before surgery,3 days after surgery,and 7 days after surgery.The international prostate symptom score(IPSS)was used to assess prostate symptoms,the urinary symptom distress score(USDS)was used to assess urinary symptoms,the dynamic urodynamic monitor was used to measure urodynamics[maximum flow rate(Qmax),residual urine volume(RUV)],the enzyme-linked immunosorbent assay was used to detect the serum level of total prostate specific antigen(tPSA),the international index of erectile function-5(IIEF-5)was used to assess erectile function,and the BPH quality of life(BPH-QOL)scale was used to assess quality of life before surgery,3 months after surgery,and 6 months after surgery.The incidence of complications such as urethral stricture,urinary tract irritation,bladder neck contracture,urinary retention,and secondary bleeding was compared between the two groups.Results The operation time of patients in the observation group was significantly longer than that in the control group,the intraoperative blood loss was significantly less than that in the control group,and the bladder irrigation time,catheter indwelling time,and hospitalization time were significantly shorter than those in the control group(P＜0.05).There was no statistically significant difference in the quality of prostatectomy between the two groups of patients(P＞0.05).Before surgery,there was no statistically significant difference in the levels of serum TNF-α,IL-6,MDA,and LPO between the two groups of patients(P＞0.05).On postoperative days 3 and 7,the levels of serum TNF-α,IL-6,MDA,and LPO in both groups were significantly higher than those before surgery,and the levels of serum TNF-α,IL-6,MDA,and LPO in the observation group were significantly lower than those in the control group(P＜0.05).Before surgery,there was no statistically significant difference in the IPSS and USDS scores between the two groups of patients(P＞0.05).At 3 and 6 months after surgery,the IPSS and USDS scores of patients in both groups were significantly lower than those before surgery,and the IPSS and USDS scores of patients in the observation group were significantly lower than those in the control group(P＜0.05).Before surgery,there was no statistically significant difference in RUV,Qmax,and serum tPSA levels between the two groups of patients(P＞0.05).At 3 and 6 months after surgery,the RUV and serum tPSA levels of patients in both groups were significantly lower than those before surgery,while the Qmax was signifi-cantly higher than that before surgery(P＜0.05).The RUV and serum tPSA levels of patients in the observation group were significantly lower than those in the control group,while the Qmax was significantly higher than that in the control group(P＜0.05).Before surgery,there was no statistically significant difference in the IIEF-5 and BPH-QOL scores of patients between the two groups(P＞0.05).At 3 and 6 months after surgery,the IIEF-5 scores of patients in both groups were significantly lower than those before surgery,while the BPH-QOL scores were significantly higher than those before surgery(P＜0.05).The IIEF-5 and BPH-QOL scores of patients in the observation group were significantly higher than those in the control group(P＜0.05).The total incidence of complications in the control group and the observation group was 16.67％(10/60)and 5.00％(3/60),respectively,and the total incidence of complications in the observation group was significantly lower than that in the control group(x2=4.227,P＜0.05).Conclusion Green laser anatomical vaporization in the treatment of BPH patients with T2DM can optimize the surgical process,reduce inflammatory stress and the risk of complications,promote early postoperative recovery,improve urodynamics and sexual function,relieve symptoms,and enhance quality of life.

ObjectiveTo provide basic data of daily dietary intake from various food categories as well as in different regions， seasons， genders， and age groups in Shanghai residents aged 15 and over. MethodsMultistage stratified proportional probability sampling （PPS） was used to extract the samples， and food frequency questionnaire （FFQ） was used to investigate the dietary intake of the subjects in four seasons from 2012 to 2013. The weighted statistical analysis of the samples comprehensively considered the sampling design weights， the stratified adjustment weights， and the non-response adjustment weights. ResultsThe total daily dietary intake （excluding drinking water） of residents aged 15 years and above was 1 174.71 g， and the highest three daily dietary intake categories were cereals （252.31 g）， vegetables （205.36 g） and fruits （141.00 g）. The total daily dietary intake of the residents in the urban area， the suburban area and the rural area was 1 209.15 g，1 172.27 g and 948.50 g， respectively， and the total daily dietary intake in the outer suburb area was significantly lower than that in other areas （F=74.12，P<0.001）. The total daily dietary intake in different seasons was 1 232.47 g in spring， 1 166.80 g in summer， 1 241.15 g in autumn and 1 088.83 g in winter， respectively. The total daily dietary intake in winter was lower than that in other seasons （F=15.96，P<0.001）. Fruits and beverages intake showed apparent seasonality. The total daily dietary intake in male and female residents was 1 234.03 g and 1 112.32 g， respectively， and the total daily dietary intake of male was higher than that of female （F=78.59，P<0.001）. The total daily dietary intake of residents in different age groups was 1 218.64 g for 15‒44 years old， 1 141.27 g for 45‒59 years old， and 1 064.54 g for 60 years old and above （F=20.28，P<0.001）. ConclusionThe daily intake of cereals， livestock and poultry meat， aquatic products， eggs and edible oil is relatively balanced， but the daily intake of vegetables， fruits and milk is relatively insufficient for the residents aged 15 years and above in Shanghai. The daily intake of different food types shows distinguishable characteristics in urban and rural areas， seasons， age groups and genders.

Objective:To investigate multimodality imaging characteristics and clinical features of lymphomatosis cerebri (LC) and reasons for misdiagnosis,with the goal of potentially facilitating an early and accurate diagnosis for this often-missed disease.Methods:Clinical data and cerebral multimodality imaging findings from 11 patients with LC proven basing on pathology in the Affiliated Hospital of Guizhou Medical University from November 30, 2011 to December 28, 2020 were retrospectively extracted, analyzed, and reviewed in combination with the literatures.Results:The common presenting symptoms with subacute onset included cognitive decline (8/11), gait disturbance (9/11), and behavioral disturbance (5/11). Test of cerebrospinal fluid showed that the number of cells and the level of protein increased (8/10), the sugar content (2/10) and chloride (4/10) decreased. The imaging manifestations of 11 patients with LC were diffuse lesions of bilateral cerebral white matter in the both deep and lobar lesion distribution, involving the cerebral cortex and subcortical white matter in eight cases (8/11), basal ganglia in seven cases (7/11), thalamus in five cases (5/11), cerebellum in six cases and brain stem in six cases (6/11). All 11 patients showed equal or slightly low-density shadows on CT plain scan and slightly longer T 1WI and T 2WI signals on magnetic resonance imaging. Six cases (6/11) had no obvious enhancement in the early stage, and five cases and six follow-up cases showed heterogenous spots, patches, nodules or clusters of distinct enhancement. Diffusion-weighted imaging showed non restricted diffusion in nine (9/11) cases initially diagnosed, and restricted diffusion in two cases (2/11) and nine follow-up cases, which were hyperintense on diffusion-weighted imaging and hypointense on apparent diffusion coefficient maps. Five patients (5/5) presented a marked decrease in N-acetyl aspartic acid (NAA)/creatine (Cr) and increase in choline (Cho)/Cr on hydrogen proton magnetic resonance spectrum, including an increase in lipid/Cr in three cases. One case (1/3) showed no abnormal increase in lesion metabolism, and two cases (2/3) showed slightly increased uptake on positron emission tomography/CT. Conclusions:Diffuse bilateral cerebral lesions especially in deep and lobar region, without enhancement or with patchy enhancement, marked decrease in NAA/Cr and increase in Cho/Cr and Lip/Cr are suggestive of LC. Misdiagnosis may be mainly due to insufficient understanding and improper brain biopsy.

With the aggravation of aging and the increasing demand of the elderly for pension and medical services,the old-age model of medical care combined with nursing emerges as the times required.Traditional Chinese medicine medical institutions have the advantages and opportunities in the process of developing integrated medical and nursing services,such as the treatment and prevention of chronic diseases,the increasing demand of the elderly for integrated medical and nursing institutions,and the strong support of the state for integrated medical and nursing institutions.However,they are also facing challenges and difficulties such as imperfect team,weak market competition and low payment ability.Through the analysis of opportunities and challenges for TCM medical institutions,this paper provides corresponding counter measures and suggestions for their development.

Nonalcoholic fatty liver disease (NAFLD) is one of the common causes for chronic liver diseases, which progress gradually from nonalcoholic type simple fatty liver disease to hepatitis, cirrhosis and even liver failure and hepatocellular carcinoma. Sarcopenia is a progressive disease characterized by reduced skeletal muscle mass and function in association to metabolic dysfunctions. Recent studies have shown that the occurrence and development of NAFLD and sarcopenia are related, and there is a common base for the pathogenesis between the two, which may promote each other for mutual risk factors. This article reviews the current research progress of this field in order to clinically further understand the pathogenesis and intrinsic links between the two to look for appropriate interventions.

Objective Non-motor symptoms are important prodromal characteristics of Parkinson's disease (PD).The siblings and the spouses of PD patients do not have classic motor symptoms.This study aimed to investigate if they have PD prodromal symptoms.Methods A total of 98 PD patients from the Affiliated Hospital of Yangzhou University were recruited between January 2015 and August 2017;256 siblings of these patients were included in a siblings group,87 spouses of PD patients were included in a spouses group and 250 healthy individuals were included in a control group.Various scales were used to assess non-motor symptoms,including depression,anxiety,cognitive function,sleep status,constipation,daytime sleepiness,subjective olfactory disorder,rapid-eye-movement sleep behavior disorder (RBD),and restless legs syndrome (RLS).Results The incidence of anxiety (OR=3.06,95％CI 1.86-5.05,P＜0.01),depression (OR=2.16,95％CI 1.16-4.04,P=0.01),RBD (OR=3.83,95％CI 1.79-8.19,P＜0.01) and subjective olfactory disorder (OR=4.48,95％CI 2.02-9.90,P＜0.01) was higher in the siblings group than the control group.There were not statistically significant differences in constipation,cognitive impairment,sleep disorder,daytime sleepiness,and RLS between the two groups.There were not statistically significant differences in non-motor symptoms between the spouses group and the control group,except that the mild depression (OR=2.58,95％CI 1.07-6.20,P =0.03) in the spouses group was more obvious.Conclusions The siblings of PD patients are more likely to have PD prodromal symptoms compared with those without PD family history,perhaps because PD patients and their siblings have common pathogenic genetic factors and early living environment for neurodegeneration.There are no obvious non-motor symptoms in the spouses of PD patients.It can be concluded that the onset of PD is not related to the family life environment in adulthood.

At present, there are many problems in the dissemination of new media of Chinese medicine culture, such as "bad communicators", "unsound dissemination of content, serious commercialization" and "less targeted communication". The reasons underlying may be related to the beginning of the new media dissemination of Chinese medicine culture, the imperfect auditing and supervision mechanism and inadequate related research. Therefore, it is necessary to strengthen the access management of communicators, strengthen the management of communication content audit, build TCM knowledge base, strengthen industry regulation, and strengthen audience research and analysis, so as to promote its sustainable development.
