Objective:Bibliometric analysis of SCI papers in Shanghai tertiary obstetrics and gynecology specialized hospitals from 2017 to 2021 was conducted to provide reference for further improving management measures and optimizing the quality of SCI papers in specialized hospitals.Methods:The Web of Science database was used to retrieve SCI papers published by tertiary obstetrics and gynecology specialized hospitals in Shanghai from 2017 to 2021. Based on bibliometric methods VOSviwer 1.6.17 and Scimago Graphica 1.0.23 was adopted to analyze the number, journals, domestic and international cooperation, and hot research areas.Results:2 721 papers were published by Shanghai Tertiary A obstetrics and Gynecology hospitals from 2017 to 2021. These papers published in 765 journals. The number of papers published and publication journals increased year by year. The number of papers and journals with an impact factor of 3~5 is the largest, accounting for 37.96% and 35.95% of the total number of papers and journals respectively. However, papers and journals with more than 10 points accounted for only 7.98% and 10.20% respectively. Scientific Reports, a comprehensive journal, published the largest number of papers. International cooperation is concentrated in the United States. Domestic cooperation is concentrated in universities and research institutions in Jiangsu, Zhejiang and Shanghai. The hot research areas focused on Oncology, Obstetrics & Gynecology, Genetics, Reproductive Biology and other basic medical fields.Conclusions:The number of papers published by Shanghai's tertiary obstetrics and gynecology specialized hospitals has increased year by year, but there are fewer highly influential journals. Domestic and international scientific research cooperation is limited to several institutions. The achievements in the field of basic research are far more than those in clinical research.

Study on brain mechanism of rehabilitation training of articulation disorder in cleft lip and palate patients based on functional magnetic resonance imaging / 生物医学工程学杂志

The cleft lip and palate (CLP) is one of the most common craniofacial malformations in humans. We collected functional magnetic resonance data of 23 CLP patients before rehabilitation training (Bclp) and 23 CLP patients after rehabilitation training (Aclp), who were performing Chinese character pronunciation tasks, and performed brain activation analysis to explore the changes of brain mechanism in CLP patients after articulation disorder rehabilitation training. The study found that Aclp group had significant activation in the motor cortex, Broca area, Wernicke area and cerebellum. While the Bclp group had weak activation in the motor cortex with a small activation range. By comparing the differences and co-activated brain regions between the two groups, we found that rehabilitation training increased the activity level of negatively activated brain areas (cerebellum, left motor area, Wernicke area, etc.) to a positive level. At the same time, the activity level of weakly activated brain areas (right motor area, Broca area, etc.) was also increased. Rehabilitation training promoted the activity level of articulation-related brain regions. So that the activation intensity of articulation-related brain regions can be used as a quantifiable objective evaluation index to evaluate the effect of rehabilitation training, which is of great significance for the formulation of rehabilitation training programs.

Correlation between glycemic variability and glycosylated hemoglobin level during follow-up in elderly male patients with type 2 diabetes in Beijing / 中华内科杂志

Objective:To investigate the relationship between glycemic variability and glycosylated hemoglobin (HbA1c) level during follow-up in elderly male patients with type 2 diabetes.Methods:Retrospective cohort study. A total of 200 elderly male patients who received continuous glucose monitoring from January 2007 to January 2011 were recruited in the Second Medical Center of PLA General Hospital. The subjects were divided into two groups according to baseline mean amplitude of glycaemic excursion (MAGE) level, including MAGE <3.9 mmol/L group ( n=114) and MAGE ≥3.9 mmol/L group ( n=86). The correlation between baseline MAGE and mean HbA1c during follow-up were evaluated by univariate Pearson correlation analysis and multivariate linear regression analysis. Results:Baseline characteristics including age, body mass index, waist circumference, smoking, drinking, fasting blood glucose, blood lipid and blood pressure were comparable between MAGE <3.9 mmol/L group and MAGE ≥3.9 mmol/L group. The average follow-up period was 12.5 years. The mean HbA1c during follow-up in MAGE ≥3.9 mmol/L group was significantly higher than that in MAGE <3.9 mmol/L group (7.23%±0.72% vs. 6.91%±0.77%, t=-2.94, P=0.004). The proportion of mean HbA1c <7.0% during follow-up in MAGE ≥3.9 mmol/L group was 44.2% (38/86), which was significantly lower than that in MAGE <3.9 mmol/L group [60.5% (69/114), χ 2=5.26, P=0.022]. In univariate analysis, MAGE at baseline was correlated with the mean HbA1c during follow-up ( r=0.306, P<0.001). Multivariate linear regression analysis suggested that the baseline MAGE remained an independent influential factor of mean HbA1c ( β=0.09, 95% CI: 0.03 to 0.15, P=0.006, R2=0.31) after several confounding factors were adjusted. Conclusions:With the increased glycemic variability at baseline, mean HbA1c level during follow-up is accordingly elevated. The glycemic variability at baseline is independently related to mean HbA1c level during follow-up in elderly male patients with type 2 diabetes.

Cloning and function analysis of elongase of very long chain fatty acid gene Bmelo424 in silkworm / 生物工程学报

Genes belonging to the elongases of very long chain fatty acid (ELOVL) family affect many physiological functions in organism. In this paper, Bmelo424 gene, a member of the ELOVL family in silkworm, was cloned and its ORF was 558 bp. Its protein sequence was predicted to have four transmembrane domains, six serine phosphorylation sites, eight threonine phosphorylation sites and four tyrosine phosphorylation sites, and its subcellular localization was in the endoplasmic reticulum. Secondary structure analysis showed that the percentage of alpha-helix and beta-strand was 26.7% and 20% respectively. The results of fluorescence quantitative PCR showed that Bmelo424 gene was expressed in all tissues of silkworm, especially with the highest expression in head. By heterologous expression of Bmelo424 gene in Saccharomyces cerevisiae, the effect of Bmelo424 gene on fatty acid elongation was studied. GC-MS results indicated that the fatty acid content of C16:1n-7 in S. cerevisiae with pYES2-Bmelo424 recombinant plasmid increased significantly, whereas the content of C16:0, C18:0 and C18:1n-9 decreased. The results of temperature stress revealed that Bmelo424 gene could improve the low temperature adaptability of S. cerevisiae, but its high temperature adaptability decreased. This provides a reference for exploring the function of Bmelo424 gene in silkworm.

Relationship between the miR-96 expression in the cochlea and ABR threshold and cochlear morphology of BALB/c mice / 中国耳鼻咽喉头颈外科

OBJECTIVE Through researching the ABR threshold, the cochlear morphology and miR-96 expression in the cochlear of BALB/c mice at different month's age, to find out if the miR-96 can regulate the age related hearing loss of BALB/c mice.METHODS ABR testing, AO/PI staining and scanning electron microscope were used to observe the ABR threshold and cochlear morphology of the BALB/c mice at the ages of 3 months, 6 months, 12 months and 18 months. Real-time PCR was used to detect the expression of miR-96 in the cochlea of BALB/c mice at the ages of 3 months, 6 months, 12 months and 18 months.RESULTS The ABR thresholds of BALB/c mice were (18.5±8.3), (45.8±7.8), and (85.6±15.6) dB SPL separately at the age of 3, 6 and 12 months. At the age of 18 months, no response was observed in the ABR testing with 120 dB SPL acoustic stimulation. In the AO/PI staining, we found that the outer hair cells was apparently lost since the age of 6 months and the loss of hair cells aggravated as the month's age increased. At the age of 12 months, no outer hair cells was left, inner hair cells was lost apparently too. With the scanning electron microscope, we found the changes of deficiency, lodging, fusion, shortening and inversion in the hair cell cilia. And these changes were aggravated as the month's ages increased. At the age of 3 months, the relative expression of miR-96 (2-△CT) was 0.0225±0.0073. The relative expression of miR-96 (2-△CT) in the cochlea were 0.0162±0.0048, 0.0116±0.0048, and 0.0050±0.0014 at the age of 6 months, 12 months and 18 months separately, comparing with the relative expression of miR-96 at the age of 3 months, the differences were significant(P<0.05).CONCLUSION The hearing loss, hair cells loss, and cilia damage aggravated as the month's age increased, but the miR-96 expression in the cochlea decreased. Which suggest that miR-96 might play an important role in the age related hearing loss.

Clinical features and risk factors for irritable bowel syndrome in Migraine patients

Objective: Clinical and basic research increasingly suggests a correlation between migraine and irritable bowel syndrome [IBS]. In this study, we aimed to explore the clinical features and risk factors for IBS in migraine patients

Methods: This was a retrospective, cross-sectional study. A total of 1,112 consecutive patients from the internal medicine and emergency departments of three hospitals from June 2014 through 2016. A comprehensive interviewer-administered questionnaire was designed based on the International Classification of Headache Disorders, 3rd edition [beta version]

Results: The response rate was 94.6%. Among 1,052 participants, 287 suffered from migraine [27.3%] and 312 suffered from IBS [29.7%]. A total of 79 patients suffered from both migraine and IBS [comorbidity rate: 7.5%]. The migraine cohort exhibited a higher frequency of IBS than did the comparison cohort at baseline [P<0.05]. Migraine patients with higher headache frequency, longer length of headache history, and anxiety disorders were more likely to also suffer from IBS [P=0.015]. There were no significant differences between the two groups in age, sex, family history, duration of headache attack, migraine aura, headache intensity, or depression disorders [P>0.05]. Multiple regression analysis indicated length of headache history and headache frequency were associated with IBS

Conclusion: Migraine patients with a long headache history, recurrent episodic headache attacks, and anxiety were more likely to have IBS

The mitochondrial Na+/Ca2+exchanger may reduce high glucose-induced oxidative stress and nucleotide-binding oligomerization domain receptor 3 inflammasome activation in endothelial cells / 老年心脏病学杂志（英文版）

Background The mitochondrial Na+/Ca2+exchanger, NCLX, plays an important role in the balance between Ca2+influx and efflux across the mitochondrial inner membrane in endothelial cells. Mitochondrial metabolism is likely to be affected by the activity of NCLX because Ca2+activates several enzymes of the Krebs cycle. It is currently believed that mitochondria are not only centers of energy produc-tion but are also important sites of reactive oxygen species (ROS) generation and nucleotide-binding oligomerization domain receptor 3 (NLRP3) inflammasome activation. Methods&Results This study focused on NCLX function, in rat aortic endothelial cells (RAECs), induced by glucose. First, we detected an increase in NCLX expression in the endothelia of rats with diabetes mellitus, which was induced by an injection of streptozotocin. Next, colocalization of NCLX expression and mitochondria was detected using confocal analysis. Suppression of NCLX expression, using an siRNA construct (siNCLX), enhanced mitochondrial Ca2+influx and blocked efflux induced by glucose. Un-expectedly, silencing of NCLX expression induced increased ROS generation and NLRP3 inflammasome activation. Conclusions These findings suggest that NCLX affects glucose-dependent mitochondrial Ca2+signaling, thereby regulating ROS generation and NLRP3 in-flammasome activation in high glucose conditions. In the early stages of high glucose stimulation, NCLX expression increases to compensate in order to self-protect mitochondrial maintenance, stability, and function in endothelial cells.
