Associations and Potential Multiple Mechanisms between Subjective Hearing Loss and Cognitive Impairment.

BACKGROUND: Subjective hearing loss (SHL) refers to an individual's self-assessment of their hearing loss. The association and underlying mechanisms between SHL and cognitive impairment still necessitate elucidation. OBJECTIVES: To validate potential mechanisms between SHL and cognitive impairment. DESIGN: Cross-section. SETTING: Shanghai, China. PARTICIPANTS: A total of 2369 individuals from communities and the cognitive disorder clinic. MEASUREMENTS: All participants were subjected to a comprehensive neuropsychological assessment, encompassing the Hearing Handicap Inventory for the Elderly-Screening Version (HHIE-S). The participants' brain ß-amyloid (Aß) deposition status, plasma biomarkers associated with Alzheimer's disease (AD), and cardiovascular risk factors were also collected. RESULTS: In individuals with a heightened SHL, elevated HHIE-S score was linked to diminished cognitive and daily functioning as well as heightened levels of depressed mood. This correlation was observed in auditory memory performance but not in visual memory. The influence of SHL on cognitive function was mediated by depressed mood. SHL was associated with diabetes and smoking, whereas cognitive function was associated with hyperlipidemia and alcohol consumption. In individuals with positive brain Aß deposition, SHL demonstrated associations with cognitive function independent of plasma Aß42/40 ratio, P-tau181, neurofilament light chain, and APOE allele status. CONCLUSION: SHL has an independent effect on cognitive impairment. The findings do no provide evidence for the common cause mechanism. Instead, the findings support the presence of a cognitive resource mechanism and an impoverished environment mechanism, along with the potential for a pathological interaction mechanism.

[The triglyceride glucose index predicts the risk of nonfatal cardio-cerebrovascular disease in the Beijing community: a prospective cohort study].

Objective: To explore the characteristics of the association between the triglyceride glucose (TyG) index and nonfatal cardio-cerebrovascular disease risk in a community population. Method: This was a prospective cohort study. From December 2011 to April 2012, the first investigation was conducted among subjects with more than 40-year old who were from Shijingshan district and Pingguoyuan community in Beijing. The second investigation was conducted from April to October 2015. All the subjects were divided into three groups according to the tertile of the TyG index at baseline. The multivariate Cox proportional risk regression model was established to explore the correlation between the TyG index and nonfatal cardio-cerebrovascular disease risk and the Kaplan-Meier survival curve of the TyG index group was drawn. Subgroup analyses were performed according to age, gender, body mass index, type 2 diabetes mellitus (T2DM), hypertension, and hyperlipidemia to determine the correlation characteristics between the TyG index and nonfatal cardio-cerebrovascular disease among subgroups. Results: A total of 9 577 subjects were finally included to analyze. The mean follow-up time of this study was (34.14±3.84) months. During the follow-up, 363 subjects (3.8%) occurred nonfatal cardio-cerebrovascular disease. The multivariate Cox regression analysis results showed that the hazard ratio (HR) of nonfatal cardio-cerebrovascular disease in the high TyG index group was 1.54 (95%CI 1.19-1.98), 1.60 (95%CI 1.23-2.10), and 1.57 (95%CI 1.20-2.05) in the three models, compared with the low TyG index group. The Kaplan-Meier analysis showed that the risk of nonfatal cardio-cerebrovascular disease increased from the low-TyG index group to the high-TyG index group (P=0.015). In the six subgroups analysis, only gender was shown to have a significant interaction effect with the TyG index and nonfatal cardio-cerebrovascular disease risk. In the female population, the risk of nonfatal cardio-cerebrovascular disease is significantly increased with the increase in the TyG index level (P<0.001). Conclusions: A high TyG index is independently related to the increased risk of nonfatal cardio-cerebrovascular disease in the Beijing community population. Gender has a significant interaction with the TyG index and nonfatal cardio-cerebrovascular disease risk. Therefore, the TyG index may be a useful marker to predict the nonfatal cardio-cerebrovascular disease risk of a community population.

[Problems and puzzles in current extracorporeal cardiopulmonary resuscitation].

Extracorporeal cardiopulmonary resuscitation (ECPR) refers to the use of extracorporeal membrane oxygenation (ECMO) to ensure the perfusion of important organs after the traditional cardiopulmonary resuscitation (CCPR) has not obtained the return of spontaneous circulation (ROSC). Such cardiopulmonary resuscitation (CPR) is called ECPR. ECPR can benefit some patients with cardiac arrest, however, there are still some problems and puzzles in the implementation of ECPR, such as the implementation location of ECPR patients? Select mechanical press or manual press before ECPR start? Can ECPR be used in special patients, such as traumatic cardiac arrest (TCA), aortic dissection and immunosuppressed patients? The age limit of ECPR and the ethical issues related to ECPR. Based on the research status at home and abroad, this paper analyzes and expounds these problems, hoping to provide new ideas for the research and application of ECPR by the majority of domestic colleagues engaged in cardiopulmonary resuscitation.

Chinese Preclinical Alzheimer's Disease Study (C-PAS): Design and Challenge from PET Acceptance.

BACKGROUND: Large-scale preclinical Alzheimer's disease study based on ß-amyloid positron emission tomography (PET) has not been conducted in China. OBJECTIVES: Establish a cohort on Alzheimer's disease spectrum, especially the preclinical stages, and determine the factors influencing the acceptance of ß-amyloid PET scan screening in China. DESIGN: Longitudinal. SETTING: Shanghai, China. PARTICIPANTS: A total of 4386 participants were screened and 2451 participants who met enrollment criteria were eventually included in this report. MEASUREMENTS: The multidimensional data was collected, including comprehensive assessments, PET and magnetic resonance imaging scans, genetics, and plasma biomarkers. RESULTS: There were 571 participants in the normal cognition group, 625 participants in the subjective cognitive decline group, 155 participants in the objectively defined subtle cognitive decline group, 501 participants in the mild cognitive impairment group, 471 participants in Alzheimer's disease group, and 128 participants with cognitive impairment from other known causes. Significant differences in demographics, florbetapir PET, APOE, and neuropsychological tests were found among the groups. Eight hundred and seventeen participants (33.3%) completed the florbetapir PET scanning. Non-demented individuals with higher age, lower education years, male, with a family history of dementia, and higher self-report depression prefer to undergo PET scans. Acceptance of PET scans did not correlate with objectively assessed cognitive impairment. CONCLUSIONS: The Chinese Preclinical Alzheimer's Disease Study was designed to establish a large-scale cohort with comprehensive data collection. Our findings may help to understand the factors affecting the acceptance of ß-amyloid PET in urban areas of China and help us address the low acceptance challenge.

[Research progress of radiomics in the evaluation of microvascular invasion in hepatocellular carcinoma].

Microvascular invasion (MVI) is an independent predictor of early recurrence and poor prognosis following hepatocellular carcinoma (HCC) resection and transplantation. As a novel non-invasive diagnostic tool, radiomics can extract the quantitative imaging features of tumors and peritumoral tissues with high throughput, providing more information on tumor heterogeneity than conventional and functional imaging of visual analysis and having a good application prospect in predicting the presence of MVI in HCC patients, thereby improving the accuracy of HCC diagnosis and prognosis. The value of the multimodal radiomics method based on various imaging methods in evaluating the possibility of MVI in HCC patients is elucidated here in combination with the latest research progress.

[Clinical characteristics and risk factors of programmed death-1 inhibitors associated with thyroid gland injury].

Objective: To investigate the clinical characteristics and related risk factors of thyroid gland injury (TGI) in patients with a malignant tumor treated with a programmed death-1 (PD-1) inhibitor. Methods: A Retrospective case-control study. Data from 198 patients with a malignant tumor who received treatment with a PD-1 inhibitor in Chinese PLA General Hospital from October 2019 to October 2021 were collected and analyzed retrospectively. According to the TGI incurred after receiving treatment with a PD-1 inhibitor, patients were divided into a thyroid gland normal (TGN) group and TGI group. The prevalence, type, time of occurrence, and outcome of TGI were analyzed. The risk factors that may contribute to TGI were analyzed further by logistic regression. Results: TGI prevalence was 29.8% (59/198 cases) after treatment with a PD-1 inhibitor. There were significant differences with respect to previous radiotherapy and targeted therapy between the TGN group and TGI group (P<0.01 for both), but there were no significant differences with regard to sex, age, tumor type, previous surgery, previous chemotherapy, tumor metastasis, or type of PD-1 inhibitor (P>0.05 for all). Patients in the TGI group included those with subclinical hypothyroidism (32.2%, n=19), hypothyroidism (27.1%, n=16), thyrotoxicosis (23.7%, n=14), subclinical thyrotoxicosis (10.2%, n=6), and thyroiditis with normal thyroid function (6.8%, n=4), and the median time of occurrence (months) was 3.00, 3.00, 1.50, 1.50, and 0.80 after treatment with a PD-1 inhibitor, respectively. Among 20 patients who presented initially with thyrotoxicosis or subclinical thyrotoxicosis, 12 cases developed hypothyroidism or subclinical hypothyroidism subsequently. Logistic regression analysis suggested that previous radiotherapy (OR=3.737, 95%CI 1.390-10.046), targeted therapy (OR=3.763, 95%CI 1.553-9.117), thyroglobulin antibodies at baseline (OR=12.082, 95%CI 1.199-121.775), and thyroid-peroxidase antibodies at baseline (OR=10.874, 95%CI 1.010-117.047) were risk factors associated with the TGI caused by treatment with a PD-1 inhibitor. Conclusions: After treatment with a PD-1 inhibitor, TGI prevalence was high, especially in those with hypothyroidism or subclinical hypothyroidism. Some patients had a transition from thyrotoxicosis to hypothyroidism. Patients who underwent radiotherapy previously, had targeted therapy, or were thyroid autoantibody-positive at baseline may carry an increased risk of TGI following treatment with a PD-1 inhibitor.

[Diagnosis and treatment of 21-hydroxylase deficiency with testicular adrenal rest tumors:a report of three cases and literature review].

Objective: To provide insight into the diagnosis for clinicians, the clinical characteristics, diagnosis and treatment history of 3 patients with 21-hydroxylase deficiency (21-OHD) and testicular adrenal rest tumors (TART) were analyzed. Methods: The clinical, laboratory and imaging data of 3 male patients with 21-OHD and TART, confirmed with CYP21 gene sequencing, from May 2010 to May 2021 in the First Medical Center of Chinese PLA General Hospital were analyzed retrospectively. The treatment strategy and clinical outcome were followed up. Results: All the 3 patients were first diagnosed with bilateral adrenal mass at the age of 27-42 years old. They were 145-162 cm tall. The levels of progesterone, 17-hydroxyprogesterone, and adrenocorticotropic hormone (ACTH) of the 3 patients were relatively high, and that of luteinizing hormone (LH) and follicle-stimulating hormone (FSH) of the 3 patients were low. Testosterone level of 1 patient was significantly elevated, and that of the other 2 patients was below the lower limit of normal range. Testicular ultrasound showed heterogeneous hyperechoic masses in both testes. CT of the adrenal glands showed bilateral adrenal enlargement with mass. All 3 patients were treated with dexamethasone. After 4-96 months of follow-up, 17-hydroxyprogesterone level was kept above the median normal level. One of the patients got married and had a baby after treatment. The sizes of adrenal hyperplasia and testicular masses reduced to various degrees with the change of the testicular masses being proportional to that of adrenal hyperplasia. Conclusions: Patients with 21-OHD are prone to have TART, leading to the impaired testicular function. Early glucocorticold therapy is beneficial to the reduction of TART and restoration of testicular function.

[Clinical aspects of pregnancy-related lymphocytic hypophysitis].

Objective: To analyze clinical features, diagnosis, treatment and prognosis of pregnancy-related lymphocytic hypophysitis (LyH). Methods: The clinical data of 16 cases diagnosed as pregnancy-related LyH at Chinese PLA General Hospital between October 2010 and November 2019 were reviewed. Results: Sixteen patients were included (aged 20-40 years). All patients' symptoms occurred from the last 2 months of pregnancy to 12 months postpartum, with 6 cases in the third trimester and 10 cases during postpartum, and all the patients were diagnosed after delivery. Six patients had lymphocytic adenohypophysitis (LAH), 4 patients had lymphocytic infundibuloneurohypophysitis (LINH), 4 patients had lymphocytic panhypophysitis (LPH), and 2 had lymphocytic hypothalamitis. Eight patients presented with symptoms of intracranial space-occupying lesions, 14 patients had symptoms of anteriorpituitary hormone deficiencies, 9 patients had central diabetes insipidus (CDI), and 2 had hyperprolactinemia. Pituitary MRI showed that the pituitary presented with diffuse enlargement, pituitary stalk thickening, disappearing of high-intensity signals in posterior pituitary and space-occupying lesions in the infundibulum of hypothalamus. Nine patients were treated with immunosuppressive agent, 3 patients alleviated the space-occupying effects after surgery, and 4 patients recovered spontaneously. Fourteen patients were followed up with a period of 3-98 months. Four patients had a relapse, 2 patients had a complete remission, and 12 patients needed long-term hormone replacement therapy. Conclusions: Clinical manifestations of pregnancy-related LyH are diverse. LyH should be suspected in pregnant or postpartum women with a sellar mass to avoid missed diagnosis or misdiagnosis. Immunosuppressant therapy is effective. Overall, LyH patients have a favorable prognosis.

The safety and efficacy of endoscopic submucosal dissection for treating early oesophageal carcinoma: a meta-analysis.

INTRODUCTION: Oesophageal carcinoma is the sixth most lethal cancer in the world. At present, the choice of specific surgical methods is controversial. This study compares the safety and efficacy of endoscopic submucosal dissection and endoscopic mucosal resection in treating early oesophageal carcinoma. METHODS: We carried out a search of online databases including the Web of Science, PubMed, Embase and the Cochrane Library with no language restrictions. The inclusion criteria were patients with early oesophageal carcinoma who accepted the treatment of endoscopic submucosal dissection compared with endoscopic mucosal resection. FINDINGS: A total of 1,462 patients with 1,650 lesions from nine studies were included in the meta-analysis. When compared with the endoscopic mucosal resection group, the en bloc resection (endoscopic submucosal dissection 67.94% vs endoscopic mucosal resection 52.78%; odds ratio 19.79, p = 0.000) and complete resection (endoscopic submucosal dissection 75.57% vs endoscopic mucosal resection 59.47%; odds ratio 16.10, p = 0.000) rates were significantly higher in the endoscopic submucosal dissection group, while the local recurrence rate was significantly lower in the endoscopic submucosal dissection group (endoscopic submucosal dissection 0.08% vs endoscopic mucosal resection 2.66%; odds ratio 0.08, p = 0.000). The incidence of complications and procedural time were also tested.

Circular RNA hsa_circ_0010882 promotes the progression of gastric cancer via regulation of the PI3K/Akt/mTOR signaling pathway.

OBJECTIVE: Accumulating studies have reported that circular RNAs (circRNAs) can act as novel prognostic biomarkers in multiple malignant tumors. Here, we conducted a study to investigate the potential function and molecular mechanism of action of hsa_circ_0010882 in gastric cancer (GC). PATIENTS AND METHODS: The expression of hsa_circ_0010882 in the plasma of GC patients and in GC cell lines was verified by qRT-PCR. Its association with overall survival of GC patients was then analyzed by statistical analysis. Gain-of-function and loss-of-function assays were used to investigate the physiological function of hsa_circ_0010882 in GC cells in vitro in the context of proliferation, apoptosis, migration, and invasion. Moreover, the molecular mechanism of action of hsa_circ_0010882 was predicted using online databases and a literature review. A Western blot assay was used to detect the levels of proteins in the PI3K/Akt/mTOR signaling pathway. RESULTS: We found that hsa_circ_0010882 expression was significantly upregulated in the plasma of GC patients and GC cell lines. Increased expression of hsa_circ_0010882 was significantly correlated with tumor size and histological grade. In addition, GC patients with higher expression of hsa_circ_0010882 had significantly lower overall survival than patients with lower expression of hsa_circ_0010882. Multivariate analysis showed that hsa_circ_0010882 expression could be an independent prognostic factor for overall survival. The proliferation, migration, and invasiveness of GC cell lines were inhibited following hsa_circ_0010882 knock-down, while GC cellular apoptosis increased. Further, overexpression of hsa_circ_0010882 leads to increased proliferation, migration, and invasiveness of GC cell lines. While apoptosis was higher in the GC cell line group with low expressing hsa_circ_0010882 than the control group, no significant difference in apoptosis was detected between the hsa_circ_0010882 overexpressing and the control group. Finally, a mechanistic analysis demonstrated that the hsa_circ_0010882 was positively associated with PI3K/Akt/mTOR signaling pathway. CONCLUSIONS: Hsa_circ_0010882, as an oncogenic molecule, is highly expressed in the plasma of patients with GC and is associated with poor prognosis. It plays an important role in proliferation, migration, and invasive genotypes of GC cell lines via regulation of the PI3K/Akt/mTOR signaling pathway. Additionally, it might be a potential prognostic biomarker for GC patients.

[Jinghuaweikang capsules combined with Quadruple therapy in the treatment of Helicobacter pylori infection:a multicenter,randomized,controlled,clinical study].

Objective: To explore the efficacy of Jinghuaweikang capsules combined with Quadruple therapy in the treatment of Helicobacter pylori (H.pylori)infection. Methods: Patients who were infected with H.pylori in 7 centers in Gansu Province were recruited in this prospective simple randomized study. All the patients are divided into four groups randomly: patients in Group A1 were treated with esomeprazole (20 mg, twice a day) + pectin bismuth (200 mg, three times a day) + amoxicillin (1 000 mg, twice a day) + clarithromycin (500 mg, twice a day), while Group A2 with Jinghuaweikang capsules(160 mg, three times a day) based on group A2, Group B1 with esomeprazole (20 mg, twice a day) + bismuth pectin (200 mg, three times a day) + amoxicillin (1 000 mg, twice a day) + furazolidone (100 mg, twice a day) and Group B2 with Jinghuaweikang capsules(160 mg, three times a day) based on group B2. The treatment time was 14 days for all 4 groups. In the course of treatment, abdominal pain, acid reflux, abdominal distension, belching, hiccups were observed at the time before treatment, 14 days and 30 days after treatment and were scored. Finally, all patients received (13)C or (14)C for H.pylori at the time of 30 days after the treatment. Result: A total of 455 patients were included in 7 hospitals from February 2016 to May 2017 in Gansu province, and there were 189 male patients. Group A1 included 129 cases, group A2 96 cases, group B1 112 cases and group B2 118 cases. The eradication rates that accorded with program data analysis (PP) were A1[46.9%(60/128)], A2[63.8%(60/94)], B1[60.7%(68/112)], B2[68.6%(81/118)] (P<0.004). Compared with group A1, the eradication rate of H.pylori in group B1 and group A2 increased (P<0.001, P=0.032), there was no statistical difference between group B2 and group A2, group B1 and group B2 (P=0.208, P=0.461). According to intentional analysis (ITT), the eradication rates of H.pylori in group A1 were 46.5% (60/129),group A2 were 62.5% (60/96),group B1 were 60.7% (68/112),and group B2 were 68.6% (81/118).The radical rate of A2 was higher than A1 (P=0.017), group B2 was not higher than group B1 (P=0.208), and there was no significant difference among the other groups. The symptoms of abdominal pain, abdominal distention, acid reflux, belching and hiccup in the group A2 and group B2 were improved than those in group A1 and group B1 (P<0.05). No serious adverse reactions occurred in all groups. Conclusion: Jinghuaweikang capsules can improve the eradication rate of Helicobacter pylori, and improve the symptoms of patients.

[Clinical characteristics of central diabetes insipidus: a retrospective analysis of 230 cases].

Objective: To evaluate the clinical characteristics and etiologies of central diabetes insipidus (CDI). Methods: The clinical data of 230 patients with CDI in the Department of Endocrinology of Chinese PLA General Hospital from 2008 June to 2014 December were collected and analyzed retrospectively. Results: The three most common causes of CDI were idiopathic CDI, lymphocytic hypophysitis and intracranial germ cell tumors. Among all the CDI, the idiopathic CDI accounted for 37.48%. There were significant differences in age onset and gender distribution among the different causes of CDI. The patients with intracranial germ cell tumors [age of onset(19.2±10.2) years] were younger than the other types of CDI. Germ cell tumors patients were more common in male, and lymphocytic hypophysitis patients were more common in female. The most frequent abnormality of anterior pituitary in patients with CDI was growth hormone deficiency, followed by hypogonadism, adrenal insufficiency and hypothyroidism. The dysfunction of thyroid axis and adrenal axis in patients with germ cell tumor was more common than those in patients with idiopathic and lymphocytic hypophysitis. Conclusions: The most common causes of central diabetes insipidus were idiopathic CDI, lymphocytic hypophysitis and intracranial germ cell tumors. There were differences in age of onset, gender distribution and abnormal production of anterior pituitary hormones among all causes of CDI patients.

[Clinical characteristics of 128 hospitalized patients with syndrome of inappropriate antidiuretics of different etiologies].

Objective: To summarize and analyze the clinical features and etiologies in hospitalized patients with syndrome of inappropriate antidiuretics (SIAD) during the past 25 years. Methods: All data of 128 patients with SIAD admitted to Chinese PLA General Hospital since January 1991 to January 2016 were collected. SIAD was diagnosed based on the 1957 criterion. Results: (1) The most frequent causes of increased inappropriate secretion of vasopressin were malignant tumors, lung diseases (e. g. pneumonia), and central nervous system diseases, in which malignant tumors accounted for 38.28% of the SIAD. (2) During the past 25 years, the proportion of malignant diseases declined from 4/7 to 35.29%, while, the proportion of pulmonary infection increased from 1/7 to 35.29% (P<0.05). (3) The patients with malignant tumors had the lowest serum sodium and serum osmolality among all SIAD patients. (4) CT scan had a high diagnostic value for chest and brain detection. (5) Among three SIAD subjects with unknown reasons at onset, two were diagnosed with small cell lung cancer and one with gastric cancer during follow-up. Conclusion: The etiology of SIAD is complex and it could be attributed to multifarious etiological factors. Malignant tumors account for the largest proportion of all patients, and pulmonary infection was ranked in second place. Cautions on tumors have to be taken when serum sodium of a SIAD patient is below 118.1 mmol/L.

[An analysis of four cases of misdiagnosed primary lymphocytic hypophysitis].

To improve the differential diagnosis of sellar region mass, 4 cases with sellar mass and misdiagnosed as lymphocytic hypophysitis (LYH) were reviewed retrospectively.The 4 patients (2 male and 2 female) aged 20-60 years old were all presented with symptoms of headache, polydipsia and polyuria.Biochemical studies confirmed the diagnoses of central diabetes insipidus and hypopituitarism.Head MRI scans showed LYH like image for all the cases, and, thus, high dose methylprednisolone pulse therapy (HDMPT) was applied to the patients.Their symptoms deteriorated and the sellar mass enlarged after a short period of partial improvement.Operations were performed in all the patients.Histology study showed craniopharyngioma with abscess, primary abscess, secondary hypophysitis caused by Wegener's granulomatosis, and germinoma with secondary hypophysitis, respectively.In conclusion, surgery or biopsy is necessary for those who presented with sellar region mass and was suspected to be with LYH, but with poor response or even worse after HDMPT.
