LncRNA MCM3AP-AS1 serves as a competing endogenous RNA of miR-218 to upregulate GLUT1 in papillary thyroid carcinoma

ABSTRACT Objective: MCM3AP-AS1 has been characterized as an oncogenic long non-coding RNA (lncRNA) in several cancers including papillary thyroid cancer (PTC), but its role in PTC has not been fully elucidated. Considering the critical role of lncRNAs in cancer biology, further functional analysis of MCM3AP-AS1 in PTC may provide novel insights into PTC management. Subjects and methods: Paired tumor and non-tumor tissues were collected from 63 papillary thyroid carcinoma (PTC) patients. Expression levels of MCM3AP-AS1 , miR-218 and GLUT1 in tissue samples were analyzed by qRT-PCR. Cell transfection was performed to explore the interactions among MCM3AP-AS1 , miR-218 and GLUT1 . Cell proliferation assay was performed to evaluate the effects of MCM3AP-AS1 and miR-218 on cell proliferation. Results: MCM3AP-AS1 accumulated to high levels in PTC tissues and was affected by clinical stage. MCM3AP-AS1 showed a positive correlation with GLUT1 across PTC tissues. RNA interaction prediction showed that MCM3AP-AS1 could bind to miR-218 , which can directly target GLUT1 . MCM3AP-AS1 and miR-218 showed no regulatory role regulating the expression of each other, but overexpression of MCM3AP-AS1 upregulated GLUT1 and enhanced cell proliferation. In contrast, overexpression of miR-218 downregulated GLUT1 and attenuated cell proliferation. In addition, miR-218 suppressed the role of MCM3AP-AS1 in regulating the expression of GLUT1 and cell proliferation. Conclusions: MCM3AP-AS1 may serve as a competing endogenous RNA of miR-218 to upregulate GLUT1 in PTC, thereby promoting cell proliferation. The MCM3AP-AS1/miR-218/GLUT1 pathway characterized in the present study might serve as a potential target to treat PTC.

Geriatric benign paroxysmal positional vertigo: a single-center study

Abstract Objective To compare the clinical features, risk factors, distribution of Benign Paroxysmal Positional Vertigo (BPPV) subtypes, and effectiveness of canalith repositioning between geriatric and non-geriatric patients with BPPV. Methods A total of 400 patients with BPPV were enrolled. Canalith repositioning was performed according to the semicircular canals involved. Patients were divided by age into a geriatric group (≥60 years) and a non-geriatric group (20-59 years). Clinical characteristics, potential age-related risk factors, distribution of subtypes, and effectiveness of canalith repositioning were compared between the groups. Results Female sex was significantly more common in all age groups, with a peak female-to-male ratio of 5.1:1 in the group aged 50-59 years. There was a higher proportion of men in the geriatric group. A history of disease associated with atherosclerosis was significantly more common in the geriatric group (p< 0.05). Migraine was significantly more common in the non-geriatric group (p= 0.018), as was posterior canal BPPV. The horizontal canal BPPV (especially horizontal canal BPPV-cupulolithiasis), and multicanal BPPV subtypes were more common in the geriatric group, whereas anterior canal BPPV was more common in the non-geriatric group. Two canalith repositioning sessions were effective in 58.0% of the geriatric cases and in 72.6% of the non-geriatric cases (p= 0.002). There was a tendency for the effectiveness of canalith repositioning to decrease with increasing age. Conclusion BPPV was more common in women. However, the proportion of men with BPPV increased with age. Elderly patients often had a history of diseases associated with atherosclerosis (i.e., hypertension, diabetes, and hyperlipidemia). The horizontal canal BPPV (particularly horizontal canal BPPV-cupulolithiasis) and multicanal BPPV subtypes were more common and the anterior canal BPPV subtype was less common in elderly patients. The effectiveness of canalith repositioning may decrease with age. Therefore, older patients should receive more comprehensive medical treatment. Level of evidence: 4.

The incidence of related complications and patient comfort at 24 hours, 72 hours, 7 days and 14 days after catheterization were compared between the two groups.Results:At 24 hours and 72 hours after catheterization, the incidence of bleeding at puncture point in 0-1 cm group was 14.39%(19/132) and 9.85%(13/132), in 2-4 cm group was 30.69%(31/101) and 32.67%(33/101), the difference was statistically significant ( χ2=9.02, 14.16, both P<0.05). The rate of redness and swelling of punture point at 7 days after catheterization was 9.09%(12/132) and 40.59%(41/101) in the two groups, with statistical significance ( χ2=32.32, P<0.05). The rates of slightly prolapse at 7 and 14 days after catheterization were 18.18% (24/132) and 18.94%(25/132) in 0-1 cm group, 59.41% (60/101) and 67.33%(68/101) in 2-4 cm group, the difference between the two groups was statistically significant ( χ2=42.18, 55.86, both P<0.05). In the observation of comfort at 14 days after catheterization, the comfort score of patients in the 0-1 cm group was significantly higher than that in the 2-4 cm group, and the difference between the two groups was statistically significant ( χ2=7.34, P<0.05). Conclusions:Patients with hematologic diseases can reduce the risk of bleeding and slightly prolapse, and improve the comfort of patients when the external lengths is 0-1 cm of power PICC, which is worthy of clinical application and promotion. The catheterizer should adopt accurate in appropriate measurement method to determine the best lengths of the catheters.

Renal thrombotic microangiopathy induced by targeted therapy combined with immunotherapy: a case report / 中华肾脏病杂志

Targeted therapy and immunotherapy have achieved great success in treating various solid and non-solid tumors, but the incidence of drugs-related adverse events is relatively high. The paper reports a case of renal thrombotic microangiopathy in an intrahepatic cholangiocarcinoma patient who underwent targeted therapy combined with immunotherapy. During the treatment, the tumor burden relieved continuously, but the patient developed proteinuria, edema and hypertension. The ADAMTS13 activity and inhibitors were normal, while the antiphospholipid antibody was positive. The patient was finally diagnosed as glomerular thrombotic microangiopathy with immune complex deposition by renal biopsy. After the cease of the antineoplastic agents and treatment with "cordyceps preparations" and "α-keto acids", the patient's blood pressure dropped to normal, her urine protein turnned to weakly positive, and her renal function remained stable.

Analysis of influencing factors of medical insurance fund settlement in neonatology under DIP payment method / 中国卫生政策研究

Objective:To analyze the DIP medical insurance settlement situation of neonatology and its influencing factors,to optimize the medical insurance settlement rules of neonatology,and to promote the fine management of payment method reform.Methods:City Y,the pilot city of national DIP payment method,was selected as the case area,and the data of the whole sample of patients in neonatology department of City Y were analyzed by descriptive analysis,four-quadrant bubble chart,and multivariate linear regression methods,combined with qualitative data analysis and interview study.Results:There were 1 372 neonates in City Y in 2022,with a health insurance billing rate of 84.82%and 81.10%in tertiary care facilities.There were 718 unenrolled cases.Tertiary care institutions,not enrolled,low-birth-weight babies,higher days of hospitalization,lower days of birth,and lower settlement scores were the influencing factors for the low rate of health insurance settlement in neonatology(P<0.05).Conclusion:Neonatology medical insurance settlement rate was significantly lower than that of the city,and tertiary care institutions had higher deficits,which may lead to the risk of shirking critically ill neonatal patients.There were problems of insufficient grouping refinement and score distortion in neonatology.Recommendation:We should improve the management and adjustment mechanism of core elements,optimize the DIP grouping of neonatology,comprehensively consider the resource consumption characteristics of neonates,rationally and dynamically adjust the price of neonatal medical services,and scientifically set the neonatology markup coefficients,so as to achieve synergistic improvement in the development of neonatology and health insurance,and to push forward the connotative and refined development of the reform of the payment method of health insurance.

Impact of global budget on the medical care flow and fund allocation of non-compact medical communities from the perspective of symbiosis / 中华医院管理杂志

Objective:To analyze the impact of global budget on the medical flow treatment and fund allocation in a non-compact medical community based on the symbiosis theory, so as to provide references for relevant authorities to formulate policies for the medical community.Methods:Data on outpatient and emergency visits, discharges, and medical insurance fund usage of the leading hospital and primary medical and health institutions in a non-compact medical community were collected from the health information system of a certain city. The time range of the data spanned from January 2017 to December 2019. The total budget was implemented in April 2018. The symbiotic system of the non-compact medical community was analyzed based on the theory of symbiosis. Descriptive analysis and intermittent time series segmented regression model were used to analyze the changes in indexes related to the flow of medical treatment and fund allocation between the leading hospital and primary institutions under the global budget.Results:The non-compact medical community′s symbiotic system had developed a continuous symbiotic model in organization and an asymmetric reciprocal symbiotic model in behavior. From the perspective of medical treatment flow, the number of outpatient and emergency visits of leading hospital and primary institutions in the medical community showed an upward trend, with little change in the number of discharged patients from 2017 to 2019; The number of patients transferred by the leading hospital increased from 32 in 2017 to 87 in 2019. According to the analysis of the intermittent time series segmented regression model, after the implementation of global budget, the proportion of outpatient and emergency visits in leading hospital was decreased ( β3=-0.43, P<0.05), the proportion of outpatient and emergency visits in primary institutions was on the rise ( β3= 0.02, P<0.05). In terms of fund allocation, the share of health insurance fund of the leading hospital increased from 45.98% in 2017 to 46.51% in 2019, and the primary medical and health institutions decreased from 23.44% to 18.06%, as well as the ratio of per capita income of primary medical and health institutions to that of leading hospitals was decreased from 72.62% to 60.79%. Conclusions:Under the global budget, the outpatient and emergency medical treatment flow in a non-compact medical community had been optimized. However, there was an uneven distribution of funds among medical institutions at all levels. Thus it was recommended to continue to give full play to the positive incentive effect of the global budget, establish a scientific mechanism for distributing benefits, and strengthen supervision and management.

The goal of this article is to recognize the phenotypes (triggers and presentation) and understand its characteristics through endotypes (mechanisms) of anaphylaxis. Ultimately, the aim is to help allergists and health care providers guide a precision approach to diagnose and manage of anaphylaxis.

Genome-wide identification of bZIP family genes and screening of candidate AarbZIPs involved in terpenoid biosynthesis in Artemisia argyi / 中国中药杂志

Artemisia argyi is an important medicinal and economic plant in China, with the effects of warming channels, dispersing cold, and relieving pain, inflammation, and allergy. The essential oil of this plant is rich in volatile terpenoids and widely used in moxi-bustion and healthcare products, with huge market potential. The bZIP transcription factors compose a large family in plants and are involved in the regulation of plant growth and development, stress response, and biosynthesis of secondary metabolites such as terpenoids. However, little is known about the bZIPs and their roles in A. argyi. In this study, the bZIP transcription factors in the genome of A. argyi were systematically identified, and their physicochemical properties, phylogenetic relationship, conserved motifs, and promoter-binding elements were analyzed. Candidate AarbZIP genes involved in terpenoid biosynthesis were screened out. The results showed that a total of 156 AarbZIP transcription factors were identified at the genomic level, with the lengths of 99-618 aa, the molecular weights of 11.7-67.8 kDa, and the theoretical isoelectric points of 4.56-10.16. According to the classification of bZIPs in Arabidopsis thaliana, the 156 AarbZIPs were classified into 12 subfamilies, and the members in the same subfamily had similar conserved motifs. The cis-acting elements of promoters showed that AarbZIP genes were possibly involved in light and hormonal pathways. Five AarbZIP genes that may be involved in the regulation of terpenoid biosynthesis were screened out by homologous alignment and phylogenetic analysis. The qRT-PCR results showed that the expression levels of the five AarbZIP genes varied significantly in different tissues of A. argyi. Specifically, AarbZIP29 and AarbZIP55 were highly expressed in the leaves and AarbZIP81, AarbZIP130, and AarbZIP150 in the flower buds. This study lays a foundation for the functional study of bZIP genes and their regulatory roles in the terpenoid biosynthesis in A. argyi.

Precise diagnosis and management of anaphylaxis based on phenotypes and endotypes / 中华预防医学杂志

Anaphylaxis is the most severe allergic reaction, demanding immediate management by health care providers, which is currently underdiagnosed and undertreated in China. In addition to the classic IgE-mediated pathway, non-IgE dependent pathway has also been extensively studied in the pathogenesis of anaphylaxis. Recently, the atypical symptoms induced by widespread used monoclonal antibodies and biologics have been reported. The goal of this article is to recognize the phenotypes (triggers and presentation) and understand its characteristics through endotypes (mechanisms) of anaphylaxis. Ultimately, the aim is to help allergists and health care providers guide a precision approach to diagnose and manage of anaphylaxis.

Maxent modeling for predicting the global potential distribution of talaromycosis marneffei / 中国热带医学

@#Abstract: Objective　To predict the potential distribution of talaromycosis marneffei (TSM) and analyze its driving factors, so as to provide evidence for the surveillance and prevention of this disease. Methods　The data of all laboratory-confirmed, non-duplicating TSM published in the English and Chinese literature from the first case in January 1964 to December 2018 was collected. A Maxent ecology model using environmental variables, Rhizomys distribution and HIV/AIDS epidemic was developed to forecast ecological niche of TSM worldwide, as well as identify the driving factors. Results　A total of 705 articles (477 in Chinese and 228 in English) were obtained during the study period. After excluding imported cases, a total of 100 foci information were included in the model. The area under the receiver operating characteristic (ROC) curve (AUC) of the model was 0.997 for the training set and 0.991 for the test set. Maxent model revealed that Rhizomys distribution, mean temperature of warmest quarter, precipitation of wettest month, HIV/AIDS epidemic and mean temperature of driest quarter were the top 5 important variables affecting TSM distribution. In addition to identifying traditional TSM endemic areas (South of the Yangtze River in China, Southeast Asian, North and Northeast India), other potential endemic areas were also identified, including parts of the North of the Yangtze River, Central America, West Coast of Africa, East Coast of South America, the Korean Peninsula and Japan. Conclusion　Our finding has discovered hidden high-risk areas and provided insights about driving factors of TSM distribution, which will help inform surveillance strategies and improve the effectiveness of public health interventions against TM infections.

Influencing factors of negative conversion time of nucleic acid detection in 228 patients infected with Omicron variant of SARS-CoV-2 in Shanghai / 中国热带医学

@#Abstract: Objective To analyze and compare the effects of different clinical characteristics on the negative conversion time of nucleic acid detection after severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Omicron variant infection, and to provide a scientific basis for the isolation and treatment of coronavirus disease 2019 (COVID-19). Methods　The epidemiological and clinical data of 228 mild SARS-CoV-2 Omicron variant infected patients diagnosed in Shanghai were retrospectively collected from April 27, 2022 to June 8, 2022 in Wujiaochang designated Hospital, Yangpu District, Shanghai. The negative conversion time of nucleic acid detection was used as the outcome variable, and the patients were divided into A (≤18 days) and B (>18 days). Univariate and multivariate logistic regression analysis were used to analyze the influencing factors of the negative conversion time of nucleic acid detection. Results　The mean nucleic acid conversion time of 228 patients was (18.7±12.1) d, with the median time of 18 (2-46) d. Among them, 120 patients in group A had an average nucleic acid conversion time of (13.2±2.0) d, and 108 cases in group B had an average nucleic acid conversion time of (20.8±1.3) d. Univariate analysis showed that there were no statistically significant differences in the effects of hypertension, coronary heart disease, diabetes, hypokalemia, malignant tumors, neuropsychiatric diseases, chronic digestive diseases on the negative nucleic acid conversion time (P>0.05); however, there were significant differences in the effects of combined cerebrovascular disease, leukopenia, chronic respiratory system diseases and vaccination on the negative nucleic acid conversion time (P<0.05). Further multivariate logistic regression analysis revealed that the combination of chronic respiratory diseases and non-vaccination were significant risk factors for prolongation of negative nucleic acid conversion time (P<0.05). Conclusions The results of this study show that gender, age and whether hypertension, coronary heart disease, diabetes mellitus, hypokalemia, malignant tumor, neuropsychiatric disease and chronic digestive disease have no significant effect on the nucleic acid conversion time, whereas chronic respiratory disease and no vaccination are significantly correlated with the prolongation of nucleic acid conversion time in SARS-CoV-2 Omicron-infected patients.

Diagnosis and treatment of 4 cases imported severe malaria and COVID-19 co-infection / 中国热带医学

@#Abstract: To explore the clinical characteristics, diagnosis and treatment of imported severe malaria and COVID-19 co-infection cases, and to provide scientific basis for epidemic prevention and control measures. The epidemiological characteristics, clinical manifestations, laboratory tests, treatment process and prognosis of 4 cases of severe malaria and COVID-19 co-infection with confirmed diagnosis were analyzed retrospectively. Four cases of severe malaria were African returnees of the same batch, male, aged 40-54 years old, with the same journey track. They all had African work and life history and acute onset. The main clinical manifestations were fever (4/4), chills (3/4), chills (3/4), nausea and vomiting (3/4), diarrhea (4/4), fatigue and anorexia (4/4). Two cases had headache and dizziness, confusion, muscle aches, two cases had cough, one cases had sputum, sore throat and runny urine. All 4 cases were confirmed by positive nucleic acid detection of the new coronavirus (2019-nCOV) in throat swabs. Plasmodium falciparum was found by microscopic examination of peripheral blood smears of all patients, and all of them were consistent with high altitude helminthiasis. All cases were accompanied by abnormal liver function and severe hypoproteinemia, two cases were hyperbilirubinemia, three cases were dyslipidemia, three cases were involved in abnormal tertiary hemogram with different degrees of elevation of procalcitonin, two cases were lactic acid poisoning, and one case was hypoglycemia. One case showed viral pneumonia on chest CT. All cases were treated individually according to the different conditions and were discharged after improvement, and were rechecked for 2019-nCOV nucleic acid and microscopic examination of blood smear negative for Plasmodium.During the global COVID-19 epidemic, the emergence of coinfection cases of con-infection of imported malaria parasites and severe acuterespiratory syndrome coronavirus 2 (SARS-CoV-2) makes the clinical diagnosis and treatment more complicated. It is important to establish the awareness of simultaneous prevention and diagnosis of COVID-19 and malaria for local prevention and control and early warning of severe cases, and timely and effective formulation of treatment plan to improve the comprehensive treatment efficiency.

The relationship between the quality of residential community in childhood and cognitive function of the middle-aged and older people in China / 中华预防医学杂志

Objective: To examine the relationship between the quality of residential community in childhood and cognitive function of the middle-aged and older people in China. Methods: Based on the data of the China Health and Retirement Longitudinal Study in 2011, 10 940 people aged≥45 years who met the criteria were included. The general demographic characteristics, lifestyle, personal disease history, quality of residential community and cognitive function of the subjects were collected by using standardized questionnaires. The quality of residential community in childhood included community safety, community enthusiasm and neighborhood relationship. The cognitive function was measured in cognitive integrity and episodic memory. Multivariate logistic regression model was used to analyze the relationship between the quality of residential community in childhood and cognitive function of the middle-aged and older people. Results: The age of 10 940 subjects were (58.3±9.1) years old, with 51.5% (5 635) being female and 47.3% (5 174) having good cognitive function. The results of multivariate logistic regression model showed that compared with those who lived in an extremely unsafe, unenthusiastic and unharmonious community in childhood, there was an improvement in the cognitive function of the middle-aged and older people who lived in a relatively safe (OR=0.75, 95%CI: 0.57-1.00) and a safer (OR=0.72, 95%CI: 0.55-0.95) community, in a relatively enthusiastic (OR=0.69, 95%CI: 0.56-0.85) and a more enthusiastic (OR=0.70, 95%CI: 0.57-0.87) community, and in a less harmonious (OR=0.57, 95%CI: 0.34-0.94), relatively harmonious (OR=0.52, 95%CI: 0.33-0.83) and more harmonious (OR=0.49, 95%CI: 0.31-0.79) community during their childhood. Conclusion: There is a significantly positive relationship between the quality of residential community in childhood and cognitive function of the middle-aged and older people.
