Impact of use of iron fortified iodised salt beyond 12 months on haemoglobin levels

Background: Use of iron fortified iodised salt (IS) for 12 months, resulted in improvement in haemoglobin (Hb) in women, children and men. There is no published data on impact of DFS use beyond 12 months on Hb levels. Methods: A community based open randomised study to assess impact of use of DFS on Hb was discontinued after 12 months due to COVID 19 related lockdown. These families used IS for six months during lockdown; they were willing to continue using the salt provided for further one year. These families were re-randomized into three groups and given the assigned salt for further 12 months and Hb, ferritin and C-reactive protein (CRP) were estimated at 12 months. Results: Improvement in the mean Hb was 0.5 g/dl in women who had used IS earlier and DFS under second randomisation and 0.3 g/dl in those who had used DFS under first and second randomisation. Mean Hb at 30 months was higher in those who had used DFS for 24 months as compared to those who had used IS for 18 months and DFS for 12 months. The deterioration in mean Hb following discontinuation of DFS for 6 and 18 months was small. Conclusions: DFS use for the second year resulted in a further increase in Hb in those who had used DFS earlier. The relatively small deterioration in mean Hb following discontinuation of DFS might at least be in part due to the impact of nutrition and health education and access to health and nutrition services.

Isaacs� syndrome-possible etiopathogenesis and clinical aspects: a case report

Isaacs� syndrome (IS) is a rare condition which is characterized by peripheral nerve hyperexcitability which is due to continuous motor activity. The exact etiology for this condition is unknown yet there are several etiopathologies like autoimmune, genetic, or hereditary which can be an etiology for the IS. In our case report the likely etiology is autoimmune. Its clinical feature includes fasciculation, myokymia, and hyperhidrosis. To confirm the diagnosis mostly imaging methods of examination are performed like MRI, ultrasound, and EMG. In our patient MRI and EMG examination was performed. There are no particular therapeutic treatments that can help in this condition only symptomatic treatment can be delivered. Plasma exchange has a promising outcome for a momentary. In our case report, we propose the possible etiology of the condition.

Research progress on dental materials for preventing root caries / 口腔疾病防治

@#The high incidence and untreated rate of root caries, a common and frequently occurring oral disease with challenging treatment in elderly individuals, is the main cause of tooth loss among elderly people, as rapid development results in pulpitis and periapical periodontitis or residual crown and root, which has been regarded as one of the common chronic oral diseases seriously affecting the quality of life of elderly people. Thus, early intervention and prevention are important. Traditional dental materials for preventing root caries have been widely used in clinical practice; however, they have the disadvantages of tooth coloring, remineralization and low sterilization efficiency. A series of new dental materials for preventing root caries have gradually become a research hotspot recently, which have the advantages of promoting the mineralization of deep dental tissue, prolonging the action time and enhancing adhesion. Future caries prevention materials should be designed according to the characteristics of root surface caries and the application population and should be developed toward simplicity, high efficiency and low toxicity. This review describes current research regarding anti-caries prevention material application, serving as a theoretical underpinning for the research of root caries prevention materials, which is important for both promotion in the effective prevention of root caries and improvement in the status of oral health and the quality of life among old people.

Imaging findings of 14 cases of intestinal schwannoma / 复旦学报（医学版）

Objective To investigate the imaging features of intestinal schwannoma(IS)in order to improve the diagnostic ability of the disease.Methods The clinical and imaging data of 14 patients with surgically and pathologically confirmed IS were retrospectively analyzed,including the location,size,morphology,nature,growth pattern,CT density,MRI signal,PET/CT metabolism and other characteristics of the tumors.Results Of the 14 IS cases,the lesions of 3 cases were located in the duodenum,2 cases in the cecum,8 cases in the colon and 1 case in the rectum.The lesions were all round or oval,with an average maximum diameter of(2.4±1.1)cm.The lesions were solid in 13 cases,extraluminal growth in 10 cases,cystic degeneration in 1 case and myxoid degeneration in 1 case.Chronic inflammatory lymph nodes were seen around the diseased intestines in 9 cases,and the short diameter of lymph nodes was greater than 5 mm in 6 cases.All 14 cases of IS showed low attenuation on plain CT scan,and progressive enhancement after contrast injection,including 1 case of mild enhancement,2 cases of moderate enhancement,and 11 cases of obvious enhancement.Two cases of IS showed low signal intensity on T1WI,slightly high signal intensity on T2WI,significantly high signal intensity on DWI,and obvious progressive enhancement after contrast injection on MRI.Two cases of IS showed high metabolism on 18F-FDG-PET/CT,and the SUVmax was 9.4 and 8.8,respectively.Conclusion The imaging findings of IS were characteristic to a certain extent.They mainly manifested as solid nodules or masses derived from the intestinal submucosa,with uniform attenuation or signal intensity,obvious progressive enhancement after contrast injection,obvious hypermetabolism on 18F-FDG-PET/CT,and slightly larger homogeneous lymph nodes were common around the lesions.

Effectiveness of Tocilizumab in COVID-19 patients with pneumonia: A systematic review

Background and Objective@#COVID-19 contributes significantly to global morbidity and mortality. Age-related comorbidities elevate the risk of severe cases. Studies have recently demonstrated that widely available medications, including tocilizumab (TCZ), can manage severe symptoms. However, its effectiveness is unclear, particularly among the older population. Therefore, this review aimed to evaluate TCZ’s efficacy in managing severe pneumonia in individuals aged 50 and older.@*Methods@#We systematically search several databases and gray literature including Web of Science, CINAHL, Academic Search Complete, PsycINFO, PsycArticles, SocINDEX, CENTRAL/Cochrane Library, PubMed/MEDLINE for original research articles in English across several study designs published in the year 2020-2022. A narrative synthesis was conducted to summarize the evidence. We employed the NIH quality assessment tool for observational cohort studies to evaluate risk of bias. Additionally, we utilized GRADE to appraise the certainty of evidence.@*Results@#Among 539 screened articles, only five studies met the selection criteria. Tocilizumab's impact on severe COVID-19 pneumonia revealed a diverse effect on mortality rate, with 29% in the TCZ group, and 40% in the controls died within 30 days of intubation (OR 0.61; 95% CI, 0.27-1.36). It is also reported that TCZ was not associated with mortality, despite faster decline in pulmonary function and prolonged fever. Hospital mortality in the TCZ group was significantly lower than in the controls, and age over 60 was the only significant risk factor. Moreover, administering TCZ reduced mechanical ventilation needs, with 82% extubated compared to 53% in controls. However, 45% in TCZ group was associated with a higher ventilator-associated pneumonia rate than in the untreated group which was 20% (P < 0.001). Despite this, TCZ-treated patients had shorter hospital stays.@*Conclusions@#The effects of tocilizumab on reducing mortality risk and improving the survival rate of COVID-19 patients with pneumonia remained inconclusive. Yet, the majority of results suggested that giving tocilizumab leads to shorter hospital stays, lowers the requirement for mechanical ventilation, and decreases the likelihood of ICU transfer. Tocilizumab is linked to the incidence of secondary infections; hence, this medication should be closely monitored for side effects.

Research on the Path of Integrating the Life View of "Human Life is Most Important" in Traditional Chinese Medicine into Medical Ethics Education for Medical Students / 中国医学伦理学

The life view of "human life is the most important" in Traditional Chinese Medicine (TCM) originates from the people-oriented theory of Chinese traditional culture, the benevolence thought of Confucianism, the rebirth thought of Taoism and the compassion thought of Buddhism. Taking the life view of "human life is the most important" as the starting point, it has formed medical ethics thoughts such as the social responsibility of saving the world, the medical practice purpose of treating all patients equally, the meticulous working attitude, the diligent and tireless learning attitude, and the exploration spirit of widely exploring the medical roots, which still has important educational significance. Therefore, the life view of "human life is the most important" should be integrated into the medical ethics education of medical students, and the medical ethics literacy of medical students should be improved through the following ways: strengthen the vocational ideal education of saving the dying and healing the wounded, and enhance the sense of social responsibility of medical students; consolidate the theme of life first classroom education and improve the professional identity of medical students; enrich and innovate the practice forms of protecting life, pay attention to the practicality of medical ethics education.

The neuroprotective effects of Herba siegesbeckiae extract on cerebral ischemia/reperfusion in rats / 中国药理学通报

Aim To study the neuroprotective effects of Herba siegesbeckiae extract on cerebral ischemia/ reperfusion rats and its mechanism. Methods Sixty SD rats were randomly divided into model group, low, middle and high dose groups of Herba siegesbeckiae, and Sham operation group, and the drug was given continuously for seven days. The degree of neurologic impairment was evaluated by mNSS, and the infarct volume was measured by MRI. The number of Nissl-posi- tive cells was detected by Nissl staining, and the apop- tosis was accessed by Tunel staining. Furthermore, the expression of Bax, Bcl-2 and NeuN was observed by Western blot, and the expression of NeuN was detected by immunofluorescence staining. The expression of IL- 1β, TNF-α and IL-6 mRNA was performed by RT- qPCR. Results The mNSS score and the volume of ischemic cerebral infarction in the model group were significantly increased, and Herba siegesbeckiae extract treatment significantly decreased the mNSS score and infarct volume (P<0.05, P<0.01). Herba siegesbeckiae extract could increase the number of Nissl-pos- itive cells and the expression of NeuN (P<0.01), and reduce the number of Tunel-positive cells (P<0.01). Western blot showed that Herba siegesbeckiae extract inhibited the expression of Bax, increased Bcl-2 and NeuN in ischemic brain tissue (P<0.01). RT-qPCR showed that Herba siegesbeckiae extract inhibited the expression of IL-1 β, TNF-α and IL-6 mRNA in the is-chemic brain tissue (P<0.01). Conclusions Herba siegesbeckiae extract can reduce the cerebral infarction volume, improve the neurological function damage, inhibit the apoptosis of nerve cells and the expression of inflammatory factors and promote the expression of NeuN, there by exerting protective effects on MCAO rats.

Meta-analysis of the efficacy of invisible orthodontic appliances for maxillary molar distalization in adult patients / 口腔疾病防治

Objective@#To evaluate the clinical efficacy of invisible orthodontic appliances without brackets for the distal movement of maxillary molars to improve the ability of orthodontists to predict treatment outcomes.@*Methods@#Web of Science, Cochrane Library, Embase, PubMed, Wanfang Database, CNKI Database, and VIP Database were searched for studies investigating the efficacy of invisible orthodontic appliances for distal movement of maxillary molars in adult patients and published from database inception to August 1, 2023. A total of three researchers screened the studies and evaluated their quality and conducted a meta-analysis of those that met quality standards.@*Results@#This study included 13 pre- and postcontrol trials with a total sample size of 281 patients. The meta-analysis revealed no significant differences in the sagittal or vertical parameters of the jawbone after treatment when compared with those before treatment (P>0.05). The displacement of the first molar was MD=-2.34, 95% CI (-2.83, -1.85); the displacement was MD=-0.95, 95% CI (-1.34, -0.56); and the inclination was MD=-2.51, 95% CI (-3.56, -1.46). There was a statistically significant difference in the change in sagittal, vertical, and axial tilt of the first molar before and after treatment. After treatment, the average adduction distance of the incisors was MD=-0.82, 95% CI (-1.54, -0.09), and the decrease in lip inclination was MD=-1.61, 95% CI (-2.86, -0.36); these values were significantly different from those before treatment (P<0.05).@*Conclusion@#Invisible orthodontic appliances can effectively move the upper molars in a distal direction and control the vertical position of the molars. When the molars move further away, there is some degree of compression and distal tilt movement, which is beneficial for patients with high angles. The sagittal movement of incisors is beneficial for improving the patient's profile.

Conclusión: los eventos pandémicos, por regla general, excluirían la responsabilidad por su imprevisibilidad, sin embargo, pueden encuadrarse dentro de una predictibilidad que permita acciones preventivas para resolver los riesgos a través de la gobernanza de la salud pública.

Analysis of drying kinetic of brewer ́s spent grains: effect of the temperature on the physical properties and the content of bioactive compounds / Análisis de la cinética de secado del bagazo residual de malta: efecto de la temperatura sobre las propiedades físicas y el contenido de compuestos bioactivos

Background: Brewer ́s spent grain (BSG) is a biomass by-product generated in large volumes during industrial beer production. BSG has become a growing environmental problem, as most breweries discard it inappropriately, negatively impacting the environment. Alternatives for the exploitation of this by-product have consisted of elaborating food supplements for farm animals, obtaining biofuels, developing adsorbents, and obtaining substances for the food industry. However, the high moisture content in BSG (approximately 70%), poses a significant challenge in exploring various reuse alternatives. Therefore, the implementation of a pre-drying process becomes essential. Objective: This study aimed to analyze the BSG drying kinetics at different temperatures and the effect of the drying temperature on the physical properties and the content of bioactive compounds. Methods: BSG samples were dried at different temperatures (50, 60, 70, 80, 90, and 105°C) and analyzed for their moisture ratio, water activity, total polyphenol content (TPC), and DPPH (1,1-diphenyl-2-picrylhydrazil) radical scavenging activity. Also, four kinetics models were fitted to the drying data. Results:It was determined that the effective diffusivity was between 5.23x10

Antecedentes: El Bagazo residual de malta (BSG por sus siglas en inglés) es un subproducto biomásico generado en grandes volúmenes durante la producción industrial de cerveza. El BSG se ha convertido en un creciente problema para el medio ambiente, debido a que la mayoría de las cervecerías descartan inapropiadamente este residuo generando un impacto negativo al ambiente. Las alternativas para el aprovechamiento de este subproducto han consistido especialmente en la elaboración de suplementos alimenticios para animales de granja, obtención de biocombustibles, desarrollo de adsorbentes y obtención de productos para la industria alimentaria. Sin embargo, el alto contenido de humedad (~70%) del BSG representa un reto para el desarrollo de diferentes alternativas de reutilización, por lo que se hace necesario un proceso de secado previo. Objetivos: En este estudio se analizó la cinética de secado del BSG a diferentes temperaturas y el efecto de la temperatura de secado sobre sus propiedades físicas y contenido de compuestos bioactivos. Métodos: Las muestras de BSG fueron secadas a diferentes temperaturas (50, 60, 70, 80, 90 y 105°C) y analizadas en términos de razón de humedad, actividad acuosa, contenido de polifenoles totales (TPC) y actividad secuestradora del radical DPPH. Además, se ajustaron 4 modelos cinéticos a los datos de secado. Resultados: Se determinó que la difusividad efectiva del BSG varió entre 5.23x10

Effects of staged acupuncture on endometrial receptivity and anxiety in patients with recurrent implantation failure of thin endometrium based on "thoroughfare vessel is the sea of blood" theory / 中国针灸

OBJECTIVE@#To compare the clinical efficacy between staged acupuncture based on "thoroughfare vessel is the sea of blood" theory combined with routine hormone replacement cycle treatment and routine hormone replacement cycle treatment for patients with recurrent implantation failure (RIF) of thin endometrium.@*METHODS@#A total of 72 RIF patients with thin endometrium were randomly divided into an observation group and a control group, 36 cases in each group. The patients in the control group were treated with routine hormone replacement cycle treatment. Based on the treatment of the control group, the patients in the observation group were treated with staged acupuncture based on "thoroughfare vessel is the sea of blood" theory. The main acupoints were Neiguan (PC 6) and Gongsun (SP 4), and the supplementary acupoints were selected according to the menstrual cycle and syndrome differentiation; the acupuncture was given once every other day, 3 times a week, for 3 consecutive menstrual cycles. The thickness and shape of endometrium, and Hamilton anxiety scale (HAMA) score were observed at implantation window before and after treatment; the clinical pregnancy rate, live birth rate and cycle cancellation rate were compared between the two groups; the correlation between endometrial thickness and HAMA score was analyzed.@*RESULTS@#Compared before treatment, the endometrial thickness in the two groups and the proportion of type A+B endometrium in the observation group were increased (P<0.05), and the HAMA scores in the two groups were decreased (P<0.05) after treatment. The above indexes in the observation group were superior to those in the control group (P<0.05). The clinical pregnancy rate and live birth rate in the observation group were higher than those in the control group (P<0.05), and the cycle cancellation rate was lower than that in the control group (P<0.05). There was a negative correlation between endometrial thickness and HAMA score (P<0.05).@*CONCLUSION@#Based on the routine hormone replacement cycle treatment, the addition use of staged acupuncture based on "thoroughfare vessel is the sea of blood" theory could improve the thickness and shape of endometrium, relieve anxiety, increase the clinical pregnancy rate and live birth rate, and reduce the cycle cancellation rate in RIF patients with thin endometrium. The curative effect is superior to the routine hormone replacement cycle treatment alone.

Treatment of leukaemia hemorrhage from the perspective of "Excessive Qi is Fire" / 国际中医中药杂志

Leukemia is a type of common hematopoietic system tumor with fever, leukocytosis, anemia and hemorrhage as the main clinical symptoms. Leukemia can be divided into acute leukemia and chronic leukemia. TCM believes that leukaemia is closely related to latent pathogen and fire toxin. Based on the theory of "excessive qi is fire", this article believed that the pathogenesis of leukemia hemorrhage is the transformation of bone marrow pathological qi into fire, clarified the relationship between leukemia cells and "fire", and proposed that the basic principle of treatment should be strengthening the body and reduce fire, supplementing with methods such as clearing heat and detoxifying, tonifying qi and nourishing yin, so as to provide references for clinical treatment.

Exploring the mechanism of Erigeron breviscapus in the treatment of ischemic stroke based on network pharmacology and molecular docking technology / 神经解剖学杂志

Objective:To explore the potential molecular mechanism of Erigeron breviscapus in the prevention and treatment of ischemic stroke through network pharmaco-molecular docking.Methods:The Chinese Herbal Medicine Systematic Pharmacology Platform(TCMSP)database provided active ingredients and potential targets of Erigeron breviscapus.Ischemic stroke-related targets were searched through the Online Mendelian Inheritance in Man(OMIM)database,the bioinformatics and chemoinformatics(DrugBank)database and human gene comprehensive database(GeneCards).The targets criteria were de-weighted by the Protein Data Bank(Uniprot)and imported into the Venny online platform to obtain the intersecting targets of both.The intersecting targets were visualized by STRING database and Cytoscape 3.7.1 software for protein-protein interaction(PPI),followed by the enrichment analysis of intersection targets for gene ontology(GO)function and Kyoto Encyclopedia of Genes and Genomes(KEGG)pathway.AutoDock Vina1.5.6 software was used to verify the molecular docking of key active ingredients and core targets and realize the vi-sualization of docking results.Results:Eleven active ingredients and 176 targets were obtained.There were 690 targets ischemic stroke-related targets and 69 intersection targets.Through PPI network,10 core genes were screened according to the degree value,including tumor necrosis factor(TNF),interleukin-6(IL-6),serine/threonine protein kinase 1(AKT1),interleukin-1β(IL-1β)and vascular endothelial growth factor A(VEGFA).KEGG enrichment included the advanced glycation end products-receptor(AGE-RAGE)signaling pathway,interleukin-17(IL-17)signaling pathway,tumor necrosis factor(TNF)signaling pathway,etc.The top 3 active ingredients and the top 5 target proteins were selected according to the degree value,and the molecular docking results demonstrated a considerable binding ability.Conclusion:Erigeron breviscapus in the treatment of ischemic stroke may work through multiple active ingredients,such as quercetin,kakaferol,and luteolin,which act on TNF,IL-6,AKT1,IL-1β,and VEGFA,and through a varie-ty of signaling pathways such as IL-17,TNF,etc.showing the characteristics of multi-components,multi-targets,and multi-pathways.

Study on the Spatial-Temporal Deduction of the Mechanism and the Modernization of the System of"Syndrome-Prescription-Herbs"in tocolysis Based on the Theory of"Fetal Stem is Tied to the Spleen" / 世界科学技术-中医药现代化

Modern Traditional Chinese Medicine(TCM)physicians believed that"reproduction depends on the kidney"theory is the key in treating fetal leakage,fetal restlessness,slippery fetus and other diseases.However,before the Ming and Qing Dynasties,ancient physicians paid special attention to the theory of"Qi and blood in the spleen and stomach".The"the stem of fetal ties the spleen"came from the summary of Zhao Xianke's"Handan manuscripts"based on analogy of nature in Ming dynasty.However,at present,the relevant research reports on"spleen"and tocolysis are fragmented,and the theoretical traceability,clinical effects and experimental research are not systematically discussed.Based on the"fetal stem ties the spleen"theory,through integrated research,taking the differentiation of ancient and modern theories of traditional Chinese medicine gynecology as the"longitude",and the progress of modern biological research on"syndromes,prescriptions and components"as the"latitude".This study is an initial attempt to reveal the key inflection points deductively in the empty space(territorial schools)during(history and history of)tocolysis,and to systematically explore the"spleen main Qi","spleen main transportation","spleen main rising Qing"and"spleen main muscle",which are associated with the progress of the objectification and the bottleneck of research on the treatment of tocolysis.Furthermore,it is proposed that TCM prescription syndrome metabolism and spatiotemporal omics are the important trends to solve the disputes and difficulties in the study of tocolysis in the future,and provide a new reference idea for the inheritance,innovation,breakthrough and accurate research of modern TCM reproductive theory.

Research Progress of Sweet Taste Receptors in the Pathogenesis of Type 2 Diabetes Mellitus and the Effect of Traditional Chinese Medicine / 世界科学技术-中医药现代化

Type 2 Diabetes Mellitus(T2DM)is a chronic metabolic disease characterized by disorders of insulin and glucose.As a disease closely related to our daily diet,the molecular mechanism of its pathogenesis is still unclear.Sweet taste receptors are a kind of G protein-coupled receptors with 7 times transmembrane.Although the research on the pathogenesis of T2DM has been gradually deepened,there are few studies on the mechanism of sweet taste damage in the state of disease.Therefore,in-depth study of the pathological mechanism of T2DM sweet taste receptor damage is of great significance to further understand the molecular characteristics of sweet taste receptors and explore new targets of traditional Chinese medicine in the treatment of T2DM.In this paper,the biological characteristics of sweet taste receptors,signal transduction mechanism of sweet taste receptors,sweet taste receptors and T2DM,sweet taste receptors and"spleen is sweet"are reviewed in order to provide the latest opinions for the targeted prevention and treatment of this kind of diseases by traditional Chinese medicine and the elucidation of related pathological mechanism.
