ABSTRACT

Objective:To explore the feasibility of using Hirsch index(H index) to evaluate the performance of academic papers published by medical talents.Methods:67 medical talents of Wuxi People′s Hospital Affiliated to Nanjing Medical University were enrolled in the study. The numbers of papers published and citations of these talents which have been included by PubMed, Chinese Citation Database, CNKI, Wanfang, and Baidu Scholar. The H value of these talents was calculated according to the list method proposed by Rousseau R. The H index was compared with the traditional evaluation indexes of scientific research performance, such as the number of papers published, the total number of citations and the average number of citations. Pearson test was used to explore the correlation between H index and traditional evaluation index.Results:The H value of 67 talents ranged from 1 to 14. Pearson test showed that the H index was significantly correlated with the total number of papers, the total number of citations and the average number of citations at the level of 0.01, and their Pearson value was 0.746, 0.932, and 0.648 respectively.Conclusions:As a new scientific research performance evaluation system, the H index is recommended in the evaluation of medical personnel, but it needs further and sustained optimization in terms of database inclusion timespan, research work timespan, and authors ranking limit among others.

ABSTRACT

The main progress in international critical care medicine in 2020 are: the reflections on the mandatory of implementation of the 1-hour cluster treatment strategy for sepsis are still continuing; the "metabolic resuscitation" therapy, represented by large dose of vitamin C, failed to yield positive results; the global epidemic of coronavirus disease 2019 (COVID-19) continues to spread, with evidences indicating Dexamethasone, Remdesivir or interferon β-1b (IFNβ-1b), Lopinavir/Ritonavir and ribavirin as promising therapy; conservative oxygen therapy did not exert positive effects neither for mechanical ventilated patients nor for acute respiratory distress syndrome (ARDS) patient; the concept of lung- and diaphragm-protective mechanical ventilation illuminates a new opportunity to potentially improve clinical outcomes for critically ill patients; there was no positive evidence for stress ulcer prophylaxis and timing of endoscopy for severe acute upper gastrointestinal bleeding; early initiation of renal-replacement therapy (RRT) for critically ill patients with acute kidney injury (AKI) has not shown positive effect. At last, artificial intelligence (AI) has shown good potential in identifying ARDS phenotypes and early predicting sepsis.

ABSTRACT

Objective:To investigate the relationship between serum microRNA-222(miR-222) and metabolism of glucose and lipid in women with polycystic ovary syndrome(PCOS).Methods:A total of 100 patients with PCOS (PCOS group) were enrolled from July 2018 to July 2020 in Puren Hospital Affiliated of Wuhan University of Science and Technology, and another 85 sterility patients were selected as control group. The levels of total cholesterol (TC), triglycerides (TG), high density lipoprotein cholesterol (HDL-C), low density lipoprotein (LDL-C), fasting insulin (FINS), fasting plasma glucose (FPG), insulin resistance index (HOMA-IR) as well as serum miR-222 were compared between two groups, and the correlation between serum miR-222 and metabolism of glucose and lipid was analyzed.Results:The levels of TC, TG, LDL-C, FPG, FINS, HOMA-IR, miR-222 in PCOS group were higher than those in the control group: (1.30 ± 0.25) mmol/L vs. (1.04 ± 0.21) mmol/L, (4.36 ± 0.91) mmol/L vs. (3.67 ± 0.61) mmol/L, (2.51 ± 0.89) mmol/L vs. (2.13 ± 0.42) mmol/L, (5.34 ± 1.56) mmol/L vs. (4.91 ± 0.84) mmol/L, (11.08 ± 3.83) mU/L vs. (7.49 ± 2.53) mU/L; the level of HDL-C in PCOS group was lower than that in the control group: (1.08 ± 0.47) mmol/L vs. (1.53 ± 0.50) mmol/L, and the differences were statistically significant ( P<0.05). The results from Logistic regression analysis showed that the levels of TC, TG, HDL-C, LDL-C, FINS, HOMA-IR, miR-222 were independent risk factors for abnormal of metabolism of glucose and lipid of polycystic ovary syndrome patients ( P<0.05). The correlation analysis showed that miR-222 expression had positive correlation with TC, TG, LDL-C, FINS, HOMA-IR ( r = 0.760, 0.737, 0.769, 0.749, 0.825, P<0.05), and had negative correlation with HDL-C( r = -0.743, P<0.05). Conclusions:The serum miR-222 shows abnormal increase in the PCOS patients, and is closely related to glucose and lipid metabolism. It can be used as a biomarker of abnormal glucose and lipid metabolism.

ABSTRACT

Heart failure (HF) is a global public health problem with high morbidity and mortality. A large number of studies have shown that HF is caused by severe energy metabolism disorders, which result in an insufficient heart energy supply. This deficiency causes cardiac pump dysfunction and systemic energy metabolism failure, which determine the development of HF and recovery of heart. Current HF therapy acts by reducing heart rate and cardiac preload and afterload, treating the HF symptomatically or delaying development of the disease. Drugs aimed at cardiac energy metabolism have not yet been developed. In this review, we outline the main characteristics of cardiac energy metabolism in healthy hearts, changes in metabolism during HF, and related pathways and targets of energy metabolism. Finally, we discuss drugs that improve cardiac function

ABSTRACT

Cancer stem cells (CSCs) are a subpopulation of cancer cells with functions similar to those of normal stem cells. Although few in number, they are capable of self-renewal, unlimited proliferation, and multi-directional differentiation potential. In addition, CSCs have the ability to escape immune surveillance. Thus, they play an important role in the occurrence and development of tumors, and they are closely related to tumor invasion, metastasis, drug resistance, and recurrence after treatment. Therefore, specific targeting of CSCs may improve the efficiency of cancer therapy. A series of corresponding promising therapeutic strategies based on CSC targeting, such as the targeting of CSC niche, CSC signaling pathways, and CSC mitochondria, are currently under development. Given the rapid progression in this field and nanotechnology, drug delivery systems (DDSs) for CSC targeting are increasingly being developed. In this review, we summarize the advances in CSC-targeted DDSs. Furthermore, we highlight the latest developmental trends through the main line of CSC occurrence and development process; some considerations about the rationale, advantages, and limitations of different DDSs for CSC-targeted therapies were discussed.

ABSTRACT

Objective To investigate the incidence and risk factors of chronic cough in children aged 6-14 years. Methods The incidence of chronic cough in children aged 6-14 years in Qinhuangdao city was investigated by questionnaire. Results A total of 4 000 questionnaires were distributed, 3 785 of them were effectively recovered, with the recovery rate of 94.6%. The incidence of chronic cough in children aged 6-14 was 5.1% (194/3 785). The prevalence rates of boys and girls were 5.4% (101/1 859) and 4.8% (93/1 926), respectively, with no significant difference (χ2=0.641,P=0.873). The incidence rate of children in industrial town area 6.7% (64/955) was significantly higher than that in urban area 4.4% (85/1 917) and agricultural town 4.9% (45/913) (χ2=55.082,P=0.000). The risk factors showed that chronic cough was associated with long-term allergen exposure, allergic constitution, asthma, rhinitis, reflux esophagitis and other nasopharynx diseases (χ2=17.833,43.370,194.466,27.773,101.92,11.268,P =0.000). Regression model analysis showed that asthma, rhinitis and allergen long-term exposure were independent risk factors of chronic cough (Wald=15.352,10.174,12.625,12.659,P =0.000). Conclusion The incidence rate of children in industrial town is higher in Qinhuangdao City than those in other urban areas, 6~14 years old children. Asthma, rhinitis and allergen exposure are the main causes of chronic cough.

ABSTRACT

Background@#Using commutable external quality assessment (EQA) materials is important for monitoring successful harmonization efforts. We assessed the commutability of four human serum pool (HSP) preparations to identify candidate EQA materials for alanine aminotransferase (ALT) and aspartate aminotransferase (AST) activity measurement. @*Methods@#One set each of 85 clinical samples (CSs) was collected for ALT and AST activity measurement. The 15 candidate EQA materials included four types of HSP preparations (A to D): materials A, C, and D contained human original recombinant (HOR) aminotransferases; materials B was mixed leftover samples. The CSs and 15 candidate EQA materials were analyzed using seven routine assays, and the ln-transformed results were analyzed in 21 assay pairs. Commutability was assessed using Deming regression, with a 95% prediction interval (CLSI approach) and the difference in bias with an error component model (International Federation of Clinical Chemistry and Laboratory Medicine [IFCC] approach). @*Results@#For ALT, all materials were commutable for 14–21 assay pairs according to the CLSI and IFCC approaches. For AST, B01-03 showed commutability for 14-21 assay pairs, and C01-03 and D01-03 showed commutability for no less than 10 assay pairs according to the two approaches. A01-06 were commutable for 9-16 assay pairs according to the CLSI approach, but for 6-9 assay pairs according to the IFCC approach. @*Conclusions@#Mixed leftover samples showed desirable commutability characteristics as candidate EQA materials for routine aminotransferase activity measurements. Human serum bases supplemented with HOR were commutable for most routine ALT activity measurements.

ABSTRACT

The origins of 9 species of the Chinese medicinal materials in the 2015 edition of the Chinese pharmacopoeia(ChP) has revised in the 2020 edition of ChP. The revision is based on the investigation and textual research on the problems found after screening the original plants, animals or minerals of all the Chinese medicinal materials in the 2015 edition. Among them the Chinese names of Alismatis Rhizoma, Cassiae Semen, Coicis Semen, Corydalis Bungeanae Herba and Echinopsis Radix all do not match to the Latin scientific names, and also do not match the name of the actual medicinal origins. In addition, Alismatis Rhizoma has the omission of original plant. There is confusion about the Chinese name and the family name of the original insect of Cera Chinensis. The original mineral of Gypsum Fibrosum has the wrong group names. Alumstone and melanterite, the original mineral of Alumen and Melanteritum respectively, of which the group names are missing. To solve these problems, field survey and literature research were conducted on the medicinal materials and their origins. The source of these problems are explored. The correct origins and the Chinese names or Latin names are all determined according to the research results to the situation, in which the Chinese and Latin names of the original plants of the medicinal materials do not match. The correct family name and group name are obtained through textual research by taxonomy if the names are confused or mis-sing. The scientific evidence and correct results of revision in the 2020 edition of ChP are determined at last.

ABSTRACT

OBJECTIVE:To investigate the effects of the integration of field processing and decoction piece processing (hereinafter called “Integration”for short )on chemical composition of Ligusticum chuanxiong decoction pieces. METHODS :Fresh L. chuanxiong were collected from Dujiangyan and Pengzhou of Sichuan ;integrated decoction pieces of L. chuanxiong were prepared after washing ,drying in the shade (to about 28% moisture content ),slicing and drying ;traditional decoction pieces was prepared after drying in the shade ,adding water to moisten (to the core ),slicing and drying. HPLC fingerprints of two kinds of decoction pieces samples (with 10 batches in each type )were established. The determination was performed on WondaSil C 18 column with mobile phase consisted of 1% formic acid solution-acetonitrile (gradient elution )at the flow rate of 1.0 mL/min. The column temperature was 30 ℃. The detection wavelength was set at 285 nm,and the sample size was 10 μL. Using ligusticolide A as reference ,HPLC fingerprints of 20 batches of samples were drawn. The similarity of the fingerprints was evaluated with Similarity Evaluation System for Chromatographic Fingerprint of TCM (2004A edition ),and then common peaks were confirmed. The contents of chlorogenic acid ,ferulic acid and ligusticolide A were determined by above chromatographic condition. Single factor variance analysis was performed for comparison of the contents. RESULTS :The similarity of HPLC fingerprints among 20 batches of samples was above 0.900. A total of 16 common peaks were determined ,7 of which were chlorogenic acid ,ferulic acid,ligusticolide Ⅰ,pine cypress ferulinate ,ligusticolide A ,n-butylphthalide and ligustilide ,respectively. The linear range of chlorogenic acid ,ferulic acid and ligusticolide A were 0.008-0.200 mg/mL(r=0.999 9),0.010-0.140 mg/mL(r=0.999 2)and 0.100-0.600 mg/mL(r=0.999 3);the limits of quantification were 0.002 8,0.000 6 and 0.005 0 mg/mL,respectively;the limits of detection were 0.000 8,0.000 1 and 0.001 0 mg/mL,respectively;RSDs of precision ,reproducibility and stability tests were all lower than 3%,and average recoveries were 96.27%-102.02%(RSD<2%,n=6). The contents of above compositions in the integrated decoction pieces and traditional decoction pieces were(1.677 0±0.311 0),(1.562 7±0.124 5),(9.494 0±1.351 3)mg/g and(1.300 2±0.469 2),(1.388 0±0.209 9),(9.811 7±1.098 9)mg/g,respectively;there was no statistical significance between 2 groups(P>0.05). CONCLUSIONS :The chemical composition of each batch of samples of L. chuanxiong integrated decoction pieces and traditional decoction pieces is consistent ,and the content of index components as chlorogenic acid ,ferulic acid and ligusticolide A in the decoction pieces is not affected by the integration processing. This process is feasible to a certain extent.

ABSTRACT

Background@#A patient’s infectivity is determined by the presence of the virus in different body fluids, secretions, and excreta. The persistence and clearance of viral RNA from different specimens of patients with 2019 novel coronavirus disease (COVID-19) remain unclear. This study analyzed the clearance time and factors influencing 2019 novel coronavirus (2019-nCoV) RNA in different samples from patients with COVID-19, providing further evidence to improve the management of patients during convalescence.@*Methods@#The clinical data and laboratory test results of convalescent patients with COVID-19 who were admitted to from January 20, 2020 to February 10, 2020 were collected retrospectively. The reverse transcription polymerase chain reaction (RT-PCR) results for patients’ oropharyngeal swab, stool, urine, and serum samples were collected and analyzed. Convalescent patients refer to recovered non-febrile patients without respiratory symptoms who had two successive (minimum 24 h sampling interval) negative RT-PCR results for viral RNA from oropharyngeal swabs. The effects of cluster of differentiation 4 (CD4)+ T lymphocytes, inflammatory indicators, and glucocorticoid treatment on viral nucleic acid clearance were analyzed.@*Results@#In the 292 confirmed cases, 66 patients recovered after treatment and were included in our study. In total, 28 (42.4%) women and 38 men (57.6%) with a median age of 44.0 (34.0–62.0) years were analyzed. After in-hospital treatment, patients’ inflammatory indicators decreased with improved clinical condition. The median time from the onset of symptoms to first negative RT-PCR results for oropharyngeal swabs in convalescent patients was 9.5 (6.0–11.0) days. By February 10, 2020, 11 convalescent patients (16.7%) still tested positive for viral RNA from stool specimens and the other 55 patients’ stool specimens were negative for 2019-nCoV following a median duration of 11.0 (9.0–16.0) days after symptom onset. Among these 55 patients, 43 had a longer duration until stool specimens were negative for viral RNA than for throat swabs, with a median delay of 2.0 (1.0–4.0) days. Results for only four (6.9%) urine samples were positive for viral nucleic acid out of 58 cases; viral RNA was still present in three patients’ urine specimens after throat swabs were negative. Using a multiple linear regression model (F=2.669, P=0.044, and adjusted R2=0.122), the analysis showed that the CD4+ T lymphocyte count may help predict the duration of viral RNA detection in patients’ stools (t=-2.699, P=0.010). The duration of viral RNA detection from oropharyngeal swabs and fecal samples in the glucocorticoid treatment group was longer than that in the non-glucocorticoid treatment group (15 days vs 8.0 days, respectively; t=2.550, P=0.013) and the duration of viral RNA detection in fecal samples in the glucocorticoid treatment group was longer than that in the non-glucocorticoid treatment group (20 days vs 11 days, respectively; t=4.631, P <0.001). There was no statistically significant difference in inflammatory indicators between patients with positive fecal viral RNA test results and those with negative results (P >0.05).@*Conclusions@#In brief, as the clearance of viral RNA in patients’ stools was delayed compared to that in oropharyngeal swabs, it is important to identify viral RNA in feces during convalescence. Because of the delayed clearance of viral RNA in the glucocorticoid treatment group, glucocorticoids are not recommended in the treatment of COVID-19, especially for mild disease. The duration of RNA detection may relate to host cell immunity.

In addition, according to the body mass index (BMI), the PCOS patients were divided into obese group (BMI ≥ 25 kg/m2, 57 cases) and non-obese group (BMI < 25 kg/m2, 43 cases). Serum level of visfatin was measured by enzyme-linked immunosorbent assay (ELISA) method, and the correlation between serum visfatin and follicle-stimulating hormone (FSH), luteinizing hormone (LH), testesterone (T), high sensitivity C-reactive protein (hs-CRP), blood lipids and blood glucose was analyzed.@*Results@#Compared with those in control group, the visfatin, BMI, diastolic blood pressure, waist and hip rate, hirsutism F-G score, FSH, LH, T, triglyeride (TG), fasting insulin (FINS), homeostasis model of assessment for insulin resistance index (HOMA-IR) in PCOS group were significantly increased: (103.20 ± 19.15) μg/L vs. (29.56 ± 4.14) μg/L, (25.81 ± 4.17) kg/m2 vs. (21.29 ± 3.74) kg/m2, (81.91 ± 10.32) mmHg (1 mmHg = 0.133 kPa) vs. (68.29 ± 7.57) mmHg, 0.91 ± 0.14 vs. 0.82 ± 0.13,(13.41 ± 2.91) scores vs. (5.98 ± 1.01) scores, (12.78 ± 1.98) U/L vs. (11.95 ± 1.51) U/L, (15.84 ± 3.16) U/L vs. (12.94 ± 1.53) U/L, (2.98 ± 0.32) nmol/L vs. (1.17 ± 0.20) nmol/L, (1.89 ± 0.43) mmol/L vs. (1.21 ± 0.11) mmol/L, (18.40 ± 2.98) mU/L vs. (11.23 ± 2.10) mU/L, 4.25 ± 0.86 vs. 2.51 ± 0.55; the high density lipoprotein-cholesterol (HDL-C) and ISI were significantly decreased: (1.46 ± 0.23) mmol/L vs. (1.55 ± 0.27) mmol/L and 0.011 ± 0.002 vs. 0.019 ± 0.005, and there were statistical differences (P<0.01 or <0.05). In addition, compared with those in non-obese group, the visfatin, BMI, diastolic blood pressure, hirsutism F-G score, FSH, LH, T, hs-CRP and TG in obese group were significantly higher, the HDL-C in obese group were significantly lower, and there were statistical differences (P<0.01 or <0.05). In PCOS group, serum visfatin level was positively correlated with BMI, diastolic blood pressure, hirsutism F-G score, FSH, LH, T, hs-CRP and TG, and serum visfatin level was negatively correlated with HDL-C (P<0.05). Stepwise multiple linear regression analysis showed that diastolic blood pressure and TG increased were the main predictors of increased visfatin level in patients with PCOS (P < 0.05).@*Conclusions@#Serum visfatin is increased in the patients with PCOS, and serum visfatin is positively related with the cardiovascular risk factors.

ABSTRACT

Objective:To establish a rat model of volume-controlled hemorrhage and observe the pathophysiological changes that ensued.Methods:Sprague Dawley (SD) rats were subjected to femoral arterial cannulation and hemorrhage for 40% or 50% of total volume. The hemodynamics data and arterial blood gas were collected, and survival after hemorrhage was monitored for 24 hours ( n=8/group). Then lung, liver, intestine and kidney were collected for HE staining after 40% hemorrhage at 4, 8 and 12 hours ( n=6/group). Results:Mean arterial pressure of 40% and 50% blood loss group decreased significantly from (90±5)mmHg and (93±4)mmHg to (40±4)mmHg and (34±4)mmHg ( P<0.05). Heart rate of 40% and 50% blood loss group increased significantly from (330±35) bpm and (336±32) bpm to (478±36) bpm and (490±21) bpm ( P<0.05). Hemoglobin and pH decreased significantly following hemorrhage, while lactate increased. The survival rate of 50% blood loss group was just 12.5% and 40% blood loss group was 100% ( P<0.05). Compared with sham group, the most significant injury was observed in lung and small intestine after 4 hours, in liver after 8 hours and in kidney after 12 hours following hemorrhage. Conclusion:This study established a stable and repeatable volume-controlled hemorrhagic shock model in rat.

ABSTRACT

Objective:To analyze the effects of angiotensin converting enzyme inhibitor/angiotensin receptor blocker (ACEI/ARB) on coronavirus disease 2019 (COVID-19) patients with hypertension, and to provide an evidence for selecting antihypertensive drugs in those patients.Methods:Clinical data were retrospectively analyzed in 58 COVID-19 patients with hypertension admitted to Shanghai Public Health Clinical Center from January 20 to February 22, 2020, including epidemiological history, clinical manifestations, laboratory findings, chest CT and outcome. Patients were divided into ACEI/ARB group and non-ACEI/ARB group.Results:Twenty-six patients were in ACEI/ARB group and the other 32 patients in non-ACEI/ARB group, with median age 64.0 (49.5, 72.0) years and 64.0 (57.0, 68.8) years respectively. The median time to onset was 5(3, 8) days in ACEI/ARB group and 4 (3, 7) days in non-ACEI/ARB group, the proportion of patients with severe or critical illness was 19.2% and 15.6% respectively. The main clinical symptoms in two groups were fever (80.8% vs. 84.4%) and cough (23.1% vs. 31.3%). The following parameters were comparable including lymphocyte counts, C-reactive protein, lactate dehydrogenase, D-dimer, bilateral involvement in chest CT (76.9% vs. 71.9%), worsening of COVID-19 (15.4% vs. 9.4%), favorable outcome (92.3% vs. 96.9%) between ACEI/ARB group and non-ACEI/ARB group respectively (all P>0.05). However, compared with non-ACEI/ARB group, serum creatinine [80.49 (68.72, 95.30) μmol/L vs. 71.29 (50.98, 76.98) μmol/L, P=0.007] was higher significantly in ACEI/ARB group. Conclusions:ACEI/ARB drugs have no significant effects on baseline clinical parameters (serum creatine and myoglobin excluded) , outcome, and prognosis of COVID-19 patients with hypertension. Antihypertensive drugs are not suggested to adjust in those patients, but the potential impairment of renal function as elevation of serum creatinine should be paid attention in patients administrating ACEI/ARB drugs.

ABSTRACT

Objective To investigate the relationship between long non-coding ovarian adenocarcinoma amplified RNA (LncRNA-OVAAL) and tumor recurrence and prognosis in uterine papillary serous carcinoma (UPSC).Methods From May 2012 to November 2016,32 patients with UPSC in our hospital were selected as observation group,and 30 patients with other benign diseases were selected as control group.Real-time polymerase chain reaction (PCR) was used to detect the expression of LncRNA-OVAAL in the enrolled patients.The receiver operating characteristic (ROC) curve was used to analyze the cutoff value of LncRNA-OVAAL.The relationship between LncRNA-OVAAL expression and clinicopathological features was analyzed.The cumulative survival rate was calculated and survival analysis was performed.The Cox risk regression model was used to analyze the single-factor and multi-factor analysis of prognosis and overall survival rate.Results The expression of LncRNA-OVAAL in patients with UPSC was elevated,which was related to age,vascular invasion,menopause,recurrence and preoperative serum human epididymis protein 4 (HE4) and carbohydrate antigen 125 (CA125) (P < 0.05).High expression of LncRNAOVAAL was a risk factor for postoperative recurrence and overall survival in patients with UPSC (P <0.05).Conclusions The high expression of LncRNA-OVAAL has a certain evaluation value for predicting postoperative recurrence and prognosis in patients with UPSC.
