Effect of anterior capsule polishing on the visual quality after cataract surgery / 国际眼科杂志(Guoji Yanke Zazhi)

AIM: To evaluate the effect of anterior capsule polishing on visual quality after phacoemulsification.METHODS: Prospective randomized control study. A total of 65 patients(73 eyes)with age-related cataract who underwent phacoemulsification combined with intraocular lens(IOL)implantation in the Emergency General Hospital between November 2021 and June 2022 were included. These patients were randomly assigned to two groups, with one group(anterior polishing group)underwent anterior and posterior capsule polishing(30 cases, 35 eyes), while the other(control group)receive routine posterior capsule polishing(35 cases, 38 eyes). Best corrected visual acuity was observed at 1wk, 1, 3 and 6mo after operation. Area of anterior capsule orifice was measured at 3 and 6mo after operation. Meanwhile, posterior capsular opacification(P score), IOL tilt and decentration were recorded by Pentacam Scheimpflug system. In addition, wavefront aberration, Strehl ratio(SR)of point spread function(PSF)and modulation transfer function(MTF)were evaluated by OPD-Scan Ⅲ.RESULTS: At 1wk, 1, 3 and 6mo after operation, best corrected visual acuity in anterior polishing group is significantly better than that of control group(P<0.05). There were no significant differences in area of anterior capsule opening, P score, IOL decentration, SR of PSF and MTF between two groups at 3 and 6mo after operation(P>0.05). At 3mo follow-up, no significant differences in IOL tilt and wavefront aberration were measured between two groups either(P>0.05). However, IOL tilt [(1.65±0.60)° vs.(2.34±0.43)°, P<0.001] and wavefront aberration(0.03±0.01μm vs. 0.06±0.03μm, P<0.001)in anterior polishing group were significant lower compared to control group at 6mo after operation.CONCLUSION: 360° polishing of anterior and posterior capsule during phacoemulsification can improve best corrected visual quality, with reduced IOL tilt, lower wavefront aberration and better visual quality.

The Memory Orchestra: Contribution of Astrocytes / 神经科学通报·英文版

For decades, memory research has centered on the role of neurons, which do not function in isolation. However, astrocytes play important roles in regulating neuronal recruitment and function at the local and network levels, forming the basis for information processing as well as memory formation and storage. In this review, we discuss the role of astrocytes in memory functions and their cellular underpinnings at multiple time points. We summarize important breakthroughs and controversies in the field as well as potential avenues to further illuminate the role of astrocytes in memory processes.

It is highly contagious and can cause death in severe cases. As reported by the World Health Organization (WHO), as of 6:36 pm Central European Summer Time (CEST), 12 August 2022, there had been 585 950 285 confirmed cases of COVID-19, including 6 425 422 deaths (WHO, 2022).

Estrogen upregulates DNA2 expression through the PI3K-AKT pathway in endometrial carcinoma / 浙江大学学报（英文版）（B辑：生物医学和生物技术）

Endometrial cancer is the most common gynecological malignancy, affecting up to 3% of women at some point during their lifetime (Morice et al., 2016; Li and Wang, 2021). Based on the pathogenesis and biological behavioral characteristics, endometrial cancer can be divided into estrogen-dependent (I) and non-estrogen-dependent (II) types (Ulrich, 2011). Type I accounts for approximately 80% of cases, of which the majority are endometrioid carcinomas, and the remaining are mucinous adenocarcinomas (Setiawan et al., 2013). It is generally recognized that long-term stimulation by high estrogen levels with the lack of progesterone antagonism is the most important risk factor; meanwhile, there is no definite conclusion on the specific pathogenesis. The incidence of endometrial cancer has been on the rise during the past two decades (Constantine et al., 2019; Gao et al., 2022; Luo et al., 2022). Moreover, the development of assisted reproductive technology and antiprogestin therapy following breast cancer surgery has elevated the risk of developing type I endometrial cancer to a certain extent (Vassard et al., 2019). Therefore, investigating the influence of estrogen in type I endometrial cancer may provide novel concepts for risk assessment and adjuvant therapy, and at the same time, provide a basis for research on new drugs to treat endometrial cancer.

Content determination of seven active components of Eucommiae Cortex in aortic vascular endothelial cells of spontaneously hypertensive rats by UPLC-MS/MS / 中国中药杂志

In the present study, the contents of seven active components [genipinic acid(GA), protocatechuic acid(PCA), neochlorogenic acid(NCA), chlorogenic acid(CA), cryptochlorogenic acid(CCA),(+)-pinoresinol di-O-β-D-glucopyranosid(PDG), and(+)-pinoresinol 4'-O-β-D-glucopyranoside(PG)] of Eucommiae Cortex in aortic vascular endothelial cells of spontaneously hypertensive rats(SHR) were simultaneously determined by ultra-high liquid chromatography-triple quadrupole mass spectrometry(UPLC-MS/MS). The qualified SHR models were selected. The primary aortic endothelial cells(VECs) of rats were separated and cultured by ligation and adherence, followed by subculture. After successful identification, an UPLC-MS/MS method for simultaneously determining the contents of GA, PCA, NCA, CA, CCA, PDG, PG in seven components of Eucommiae Cortex in VECs was established, including specificity, linearity, matrix effect, recovery, accuracy, precision and stability. The established method had the lo-west limit of quantification of 0.97-4.95 μg·L~(-1), accuracy of 87.26%-109.6%, extraction recovery of 89.23%-105.3%, matrix effect of 85.86%-106.2%, and stability of 86.00%-112.5%. Therefore, the established accurate UPLC-MS/MS method could rapidly and simultaneously determine the contents of the seven active components of Eucommiae Cortex in VECs of SHRs, which provided a refe-rence for the study of cellular pharmacokinetics of active components of Eucommiae Cortex extract.

Transcriptomics Provides Novel Insights into the Regulatory Mechanism of IncRNA HIF1 A-AS1 on Vascular Smooth Muscle Cells

ABSTRACT Introduction: Thoracic aortic aneurysm is a potentially fatal disease with a strong genetic contribution. The dysfunction of vascular smooth muscle cells (VSMCs) contributes to the formation of this aneurysm. Although previous studies suggested that long non-coding ribonucleic acid (RNA) hypoxia inducible factor 1 α-antisense RNA 1 (HIF1A-AS1) exerted a vital role in the progression and pathogenesis of thoracic aortic aneurysm, we managed to find a new regulatory mechanism of HIF1A-AS1 in VSMCs via transcriptomics. Methods: Cell viability was detected by the cell counting kit-8 assay. Cell apoptosis was assessed by Annexin V-fluorescein isothiocyanate/propidium iodide double staining. Transwell migration assay and wound healing assay were performed to check the migration ability of HIF1A-AS1 on VSMCs. The NextSeq XTen system (Illumina) was used to collect RNA sequencing data. Lastly, reverse transcription-quantitative polymerase chain reaction confirmed the veracity and reliability of RNA-sequencing results. Results: We observed that overexpressing HIF1A-AS1 successfully promoted apoptosis, significantly altered cell cycle distribution, and greatly attenuated migration in VSMCs, further highlighting the robust promoting effects of HIF1A-AS1 to thoracic aortic aneurysm. Moreover, transcriptomics was implemented to uncover its underlying mechanism. A total of 175 differently expressed genes were identified, with some of them enriched in apoptosis, migration, and cell cycle-related pathways. Intriguingly, some differently expressed genes were noted in vascular development or coagulation function pathways. Conclusion: We suggest that HIF1A-AS1 mediated the progression of thoracic aortic aneurysm by not only regulating the function of VSMCs, but also altering vascular development or coagulation function.

Anticarin-β shows a promising anti-osteosarcoma effect by specifically inhibiting CCT4 to impair proteostasis

Unlike healthy, non-transformed cells, the proteostasis network of cancer cells is taxed to produce proteins involved in tumor development. Cancer cells have a higher dependency on molecular chaperones to maintain proteostasis. The chaperonin T-complex protein ring complex (TRiC) contains eight paralogous subunits (CCT1-8), and assists the folding of as many as 10% of cytosolic proteome. TRiC is essential for the progression of some cancers, but the roles of TRiC subunits in osteosarcoma remain to be explored. Here, we show that CCT4/TRiC is significantly correlated in human osteosarcoma, and plays a critical role in osteosarcoma cell survival. We identify a compound anticarin-β that can specifically bind to and inhibit CCT4. Anticarin-β shows higher selectivity in cancer cells than in normal cells. Mechanistically, anticarin-β potently impedes CCT4-mediated STAT3 maturation. Anticarin-β displays remarkable antitumor efficacy in orthotopic and patient-derived xenograft models of osteosarcoma. Collectively, our data uncover a key role of CCT4 in osteosarcoma, and propose a promising treatment strategy for osteosarcoma by disrupting CCT4 and proteostasis.

Repeated Pseudoaneurysm after Endovascular Repair of Popliteal Aneurysm due to Graft Disintegration and Fabric Tear

Endovascular repair of popliteal artery aneurysms (PAA) using a stent graft is suitable for patients with favorable anatomy. In the domestic situation where Gore Medical withdrew, we report two cases of unusual complications of pseudoaneurysm after endovascular repair of PAA. A 44-year-old male with a history of bypass surgery for a PAA presented with recurrent vein graft pseudoaneurysm. Endovascular treatment using a domestic stent graft was performed. However, pseudoaneurysm developed due to the graft fabric tear 1 month later, requiring surgical removal. In another case, an 84-year-old female presented with acute limb ischemia related to PAA. Endovascular aneurysm repair with the same domestic stent graft was performed. However, stent graft failure occurred 2 years later and the patient underwent open surgical repair. There was a graft fabric disintegration. When proper endovascular device is not available, open surgical treatment is the best option for treating PAA.

Comparison of Reproducibility of Linear Measurements on Digital Models among Intraoral Scanners, Desktop Scanners, and Cone-beam Computed Tomography

Purpose@#Intraoral scanners, desktop scanners, and cone-beam computed tomography (CBCT) are being used in a complementary way for diagnosis and treatment planning. Limited patient-based results are available about dimensional reproducibility among different three-dimensional imaging systems. This study aimed to evaluate dimensional reproducibility among patient-derived digital models created from an intraoral scanner, desktop scanner, and two CBCT systems. @*Materials and Methods@#Twenty-nine arches from sixteen patients who were candidates for implant treatments were enrolled. Different types of CBCT systems (KCT and VCT) were used before and after the surgery. Polyvinylsiloxane impressions were taken on the enrolled arches after the healing period. Gypsum casts were fabricated and scanned with an intraoral scanner (CIOS) and desktop scanner (MDS). Four test groups of digital models, each from CIOS, MDS, KCT, and VCT, respectively, were compared to the reference gypsum cast group. For comparison of linear measurements, intercanine and intermolar widths and left and right canine to molar lengths were measured on individual gypsum cast and digital models. All measurements were triplicated, and the averages were used for statistics.Bland–Altman plots were drawn to assess the degree of agreement between each test group with the reference gypsum cast group. A linear mixed model was used to analyze the fixed effect of the test groups compared to the reference group (α=0.05).Result: The Bland–Altman plots showed that the bias of each test group was –0.07 mm for CIOS, –0.07 mm for MDS, –0.21 mm for VCT, and –0.25 mm for KCT. The linear mixed model did not show significant differences between the test and reference groups (P>0.05). @*Conclusion@#The linear distances measured on the digital models created from CIOS, MDS, and two CBCT systems showed slightly larger than the references but clinically acceptable reproducibility for diagnosis and treatment planning.reproducibility for diagnosis and treatment planning.plots showed that the bias of each test group was –0.07 mm for CIOS, –0.07 mm for MDS,

Treatment results of carotid endarterectomy and carotid artery stenting for patients with radiation-induced carotid stenosis

Purpose@#Exposure to ionizing radiation over the head and neck accelerates atherosclerotic changes in the carotid arteries. Owing to the characteristics of radiation-induced carotid stenosis (RICS), the results regarding the optimal revascularization method for RICS vary. This study compared treatment outcomes between carotid endarterectomy (CEA) and carotid artery stenting (CAS) in RICS. @*Methods@#This was a single-center retrospective review of consecutive patients who underwent CEA or CAS for carotid stenosis. RICS was defined as carotid stenosis (>50%) with the prior neck irradiation for cancer treatment on either side.For the analyses, demographics, comorbid conditions, carotid lesion characteristics based on imaging studies, surgical complications, neurologic outcomes, and mortality during the follow-up period were reviewed. To compare CEA and CAS results in RICS, a 1:1 propensity score matching was applied. @*Results@#Between November 1994 and June 2021, 43 patients with RICS and 2,407 patients with non-RICS underwent carotid revascularization with CEA or CAS. RICS had fewer atherosclerotic risk factors and more frequent severe carotid stenosis and contralateral carotid occlusions than non-RICS. CAS was more commonly performed than CEA (22.9% vs.77.1%) for RICS due to more frequent unfavorable carotid anatomy (0 vs. 16.2%). Procedure-related complications were more common in the CEA than in the CAS. However, there was no significant difference in neurologic outcomes and restenosis rates between CEA and CAS in RICS. @*Conclusion@#Considering its lesion characteristics and cumulative incidence, RICS requires more attention than non-RICS.Although CAS has broader indications for RICS, CEA has shown acceptable results if selectively performed.

ABSTRACT To explore the clinical effect of music therapy in the treatment of middle-aged and elderly patients with depression. From June 2019 to June 2020, 100 patients with depression in a community were selected as the object of this study, and were divided into a control group and an observation group according to the order of visits, with 50 patients in each group. There was no significant difference between the two groups in terms of gender, age, education level and drug treatment (medication dose, type) (P>0.05). The patients in the control group were treated with conventional antidepressant drugs. The patients in the observation group added music therapy to the conventional therapy. The music therapist needs to fully understand the basic situation of the patient and formulate a suitable music treatment plan according to the actual state of the patient. Compare the HANA and PSP scores between the two groups of depressive patients after treatment to judge the treatment effect on the patients. The Hana and PSP scores in the observation group after treatment were significantly higher than those in the control group (P<0.05). To treat depression, in addition to selecting appropriate drugs, alleviating the emotional state of patients is more important. Music therapy as an auxiliary treatment of traditional therapy, in the treatment of depression in the elderly, has been effectively verified, we should actively promote its application.

Outcomes after Elective Open Abdominal Aortic Aneurysm Repair in Octogenarians Compared to Younger Patients in Korea

Background@#Although the first choice of treatment for abdominal aortic aneurysm (AAA) is endovascular aneurysm repair, especially in elderly patients, some patients require open surgical repair. The purpose of this study was to compare the mortality outcomes of open AAA repair between octogenarians and younger counterparts and to identify the risk factors associated with mortality. @*Methods@#All consecutive patients who underwent elective open AAA repair due to degenerative etiology at a single tertiary medical center between 1996 and June 2020 were included in this retrospective review. Medical records and imaging studies were reviewed to collect the following information: demographics, comorbid medical conditions, clinical presentations, radiologic findings, surgical details, and morbidity and mortality rates. For analysis, patients were divided into two groups: older and younger than 80 years of age. Multivariate analysis was performed to identify factors associated with mortality after elective open AAA repair. @*Results@#Among a total of 650 patients who underwent elective open AAA repair due to degenerative AAA during the study period, 58 (8.9%) were octogenarians and 595 (91.1%) were non-octogenarians. Patients in the octogenarian group were predominantly female and more likely to have lower body weight and body mass index (BMI), hypertension, chronic kidney disease, and lower preoperative serum hemoglobin and albumin compared with patients in the non-octogenarian group. Maximal aneurysm diameter was larger in octogenarians. During the median follow-up duration of 34.4 months for 650 patients, the median length of total hospital and intensive care unit stay was longer in octogenarians. The 30-day (1.7% vs. 0.7%, P= 0.374) and 1-year (6.9% vs. 2.9%, P = 0.108) mortality rates were not statistically significantly different between the two groups. Multivariate analysis showed that low BMI was associated with increased 30-day (odds ratio [OR], 16.339; 95% confidence interval [CI], 1.192–224.052; P= 0.037) and 1-year (OR, 8.236; CI, 2.301–29.477; P= 0.001) mortality in all patients. @*Conclusion@#Because the mortality rate of octogenarians after elective open AAA repair was not significantly different compared with their younger counterparts, being elderly is not a contraindication for open AAA repair. Low BMI might be associated with increased postoperative mortality.

A case report of paroxysmal extreme pain disorder caused by SCN9A gene mutation / 中华实用儿科临床杂志

The clinical data of a case of paroxysmal extreme pain disorder(PEPD) in Guangdong 999 Brain Hospital were retrospectively analyzed.The male patient, age of first examination was 7 months, began to have recurrent tonic accompanied by facial redness or cyanosis at 5 months after birth.The patient was diagnosed with epilepsy.The oral solution of sodium valproate and Levetiracetam were not effective.The video electroencephalogram examination displayed that, when the patient had tonic and bradycardia, the synchro electroencephalogram did not show epileptic discharge, so the patient was considered to have non-epileptic tonic.Genetic examination suggested that SCN9A gene mutation of c. 5240T >C resulted in amino acid changes: Val1747Ala.Combined with the skin changes, the patient was diagnosed as PEPD caused by SCN9A gene mutation.After the treatment with Carbamazepine, the patient′s abnormal skin changed and his-epileptic tonic disappeared, and his condition improved significantly.The early stage of PEPD can be mainly manifested as non-epileptic tonic.It is easy to be misdiagnosed as epilepsy, so the patient′s characteristic skin changes should be noticed, and genetic examination is also helpful in the diagnosis of the disease.

Clinical significance of EPHX2 deregulation in prostate cancer / 亚洲男科学杂志(英文版)

The arachidonic acid (AA) metabolic pathway participates in various physiological processes as well as in the development of malignancies. We analyzed genomic alterations in AA metabolic enzymes in the Cancer Genome Atlas (TCGA) prostate cancer (PCa) dataset and found that the gene encoding soluble epoxide hydrolase (EPHX2) is frequently deleted in PCa. EPHX2 mRNA and protein expression in PCa was examined in multiple datasets by differential gene expression analysis and in a tissue microarray by immunohistochemistry. The expression data were analyzed in conjunction with clinicopathological variables. Both the mRNA and protein expression levels of EPHX2 were significantly decreased in tumors compared with normal prostate tissues and were inversely correlated with the Gleason grade and disease-free survival time. Furthermore, EPHX2 mRNA expression was significantly decreased in metastatic and recurrent PCa compared with localized and primary PCa, respectively. In addition, EPHX2 protein expression correlated negatively with Ki67 expression. In conclusion, EPHX2 deregulation is significantly correlated with the clinical characteristics of PCa progression and may serve as a prognostic marker for PCa.

Factors associated with long-term graft patency after lower extremity arterial bypasses

Purpose@#This study was conducted to determine factors associated with long-term graft patency after lower extremity arterial bypass (LEAB). @*Methods@#Database of LEABs for patients with chronic arterial occlusive disease (CAOD) at a single institution was retrospectively reviewed. To determine the factors we compared demographic, clinical, and procedural variables between 2 patient groups; group I (graft patency < 2 years) and group II (graft patency ≥ 5 years after LEAB) using univariable and multivariable analyses. @*Results@#Among 957 LEABs, 259 limbs (group I, 125 limbs and group II, 134 limbs) in 213 patients were included for the analysis. On a univariable analysis, younger age (69 years vs. 66 years, P = 0.024), hypertension (60.8% vs. 74.6%, P = 0.017), claudication (51.2% vs. 70.9%, P = 0.001), absence of prior intervention (50.4% vs. 73.9%, P < 0.001), common femoral artery based bypass (57.6% vs. 70.1%, P = 0.035), above-the knee bypass (36.8% vs. 64.2%, P < 0.001), postoperative graft salvage procedure (3.2% vs. 14.8%, P = 0.001), and statin use (75.2% vs. 88.8, P = 0.004) were associated with long-term patency. On a multivariate analysis hypertension (odds ratio [OR], 1.91; P = 0.038), claudication (OR, 2.08; P = 0.032), no prior intervention (OR, 2.48; P = 0.001), vein graft (OR, 4.36; P = 0.001), above-the knee bypass (OR, 4.68; P < 0.001), and graft salvage procedures (OR, 7.70; P < 0.001) were identified as independent factors. @*Conclusion@#These factors can be considered in decision making before treatment of patients with CAOD.
