Relationship between plasma SP-A expression level and disease stage in silicosis patients / 上海预防医学

ObjectiveTo investigate the relationship between plasma surfactant protein⁃A （SP⁃A） expression level and silicosis progression， and to provide early evidence for exploring whether SP⁃A can be used as a biomarker for clinical monitoring of silicosis disease progression. MethodsWe recruited 187 silicosis patients in Guangdong Province hospital for occupational disease prevention and treatment between November， 2019 and November，2020. Their peripheral venous blood samples were collected for the plasma isolation. The level of pulmonary SP⁃A was detected by enzyme-linked immunosorbent assay. ResultsThere was a statistically significant difference in the level of SP⁃A among the silicosis groups （P<0.05）， and the plasma SP-A level of the silicosis patients in stage Ⅲ was higher than that in stage Ⅰ and stage Ⅱ （P<0.05）. Smoking had effect on plasma SP⁃A levels， Age， working years and drinking had no effect on plasma SP⁃A levels. ConclusionThe expression level of SP⁃A in the plasma of silicosis patients is increased， which has a certain correlation with the disease stage， and plays a certain early warning role in the occurrence and development of silicosis， and may be a potential biomarker for the diagnosis and prognosis of silicosis.

Biological Connotation of Disease-stage-state of Hypertension in Concept of State-target Differentiation and Treatment From Perspective of Lipophagy / 中国实验方剂学杂志

Hypertension is a common chronic disease with elevated arterial pressure as the main clinical manifestation，which can cause lesions in important organs such as heart，brain and kidney. In recent years，the prevalence of hypertension has increased，and its incidence is also increasing year by year. Combining the theory of traditional Chinese medicine （TCM） with personal clinical experience，Academician TONG Xiaolin put forward the specific pathogenesis of "disease-stage-state" of hypertension based on the state-target theory. Lipophagy plays an important role in the pathogenesis of hypertension by interfering with lipid metabolism，atherosclerosis，arterial plaque formation，vascular remodeling，vascular endothelial injury and other aspects of hypertension. Through modern medical and biological research，on the one hand，it is believed that the dynamic pathological changes in lipophagy are closely related to the "stage" of hypertensive state-target differentiation and treatment，corresponding to the time points of disease occurrence and development in the three stages of hypertension. On the other hand，it is believed that lipophagy is an important microscopic manifestation of the "state" of hypertensive state-target differentiation and treatment. From the perspective of lipophagy，this paper discusses the biological connotation of the 'disease-stage-state' model of state-target differentiation and treatment of hypertension and draws on the modern medicine to understand the law of disease development，matching the macro differentiation and treatment of TCM and the micro physico-chemical indicators of modern medicine to achieve precise TCM treatment. This study provides new ideas for the early prevention and treatment of hypertension and its complications.

Expression of serum circFTO and miR-141-3p in patients with diabetes retinopathy and their relationship with pathological stage / 国际眼科杂志(Guoji Yanke Zazhi)

AIM: To explore the relationship between the changes of serum circFTO and microRNA-141-3p(miR-141-3p)levels and the different disease stages of diabetes retinopathy.METHODS: A total of 198 patients with type 2 diabetes admitted to our hospital from October 2019 to November 2022 were collected as the study subjects, the patients were grouped into non diabetes retinopathy(NDR)group(70 cases), non proliferative diabetes retinopathy(NPDR)group(66 cases)and proliferative diabetes retinopathy(PDR)group(62 cases)according to different stages; meantime, 67 volunteers with normal physical examination results were collected as the control group. The levels of serum circFTO and miR-141-3p were detected by real-time fluorescent quantitative PCR(qRT-PCR); Pearson correlation analysis was used to examine the correlation between the serum circFTO, miR-141-3p and various indicators in patients with diabetes retinopathy; multivariate Logistic regression analysis was applied to explore the influencing factors of diabetes retinopathy.RESULTS: CircFTO, systolic blood pressure(SBP), and diastolic blood pressure(DBP)in PDR group were higher than those in control group, NDR group and NPDR group, while miR-141-3p and high-density lipoprotein cholesterol(HDL-C)were lower than those in control group, NDR group and NPDR group(P&#x003C;0.05). Fasting blood glucose(FPG)and glycosylated hemoglobin(HbA1c)in NDR group, NPDR group and PDR group were higher than those in the control group(all P&#x003C;0.05). The course of disease in PDR group was longer than that in NDR group and NPDR group(P&#x003C;0.05). Serum circFTO in patients with diabetes retinopathy was positively correlated with SBP, DBP, FPG, HbA1c, and miR-141-3p was negatively correlated with SBP, DBP, FPG, HbA1c(all P&#x003C;0.05). CircFTO was a risk factor for diabetes retinopathy, and miR-141-3p was a protective factor for diabetes retinopathy(P&#x003C;0.05).CONCLUSION: Serum circFTO is obviously increased and miR-141-3p is obviously decreased in patients with diabetes retinopathy, both of them are closely related to disease stage, and are expected to become important indicators for evaluating disease progress.

Changes and significance of serum Klotho protein levels in different stages of chronic kidney disease / 中国综合临床

Objective To explore the changes and significance of Klotho protein levels in different stages of chronic kidney disease (CKD). Methods From March 2015 to December 2017,176 patients with CKD admitted to nephrology department of Inner Mongolia People＇s Hospital were selected as the study object (CKD group), and 80 healthy patients in our hospital were selected as the control group in the same period. The serum Klotho levels of CKD patients and control group at different stages were detected by double antibody sandwich ELISA, and the differences between each group were compared. Results The serum Klotho level of CKD group (( 4. 84 ± 1. 87) μg／L) was significantly lower than that of the control group ((9. 11± 3. 14) μg／L) ( t＝ 13. 82, P＜0. 01) . One-way anova showed that estimated renal glomerular filtration rate (eGFR),serum albumin (ALB),hemoglobin ( Hb),blood calcium ( Ca) and serum Klotho were gradually decreased,while phosphorus (P) and creatinine (Cr) in serum were gradually increased,and the difference was statistically significant among the five stages( all P＜0. 01). Spearman correlation analysis showed that Klotho level was positively correlated with eGFR and Ca,and negatively correlated with CKD stage,Cr and P (r＝0. 369,0. 160,－0. 200,－0. 250,－0. 230,all P＜0. 05). The multiple linear regression equation showed that Klotho level was positively and independently correlated with eGFR ( t＝ 3. 89, P＜0. 001),and negatively correlated with CKD staging independently (t＝－4. 12,P＜0. 001). Conclusion The expression level of serum Klotho protein in patients with CKD is lower than that of healthy people,and it decreases with the increase of CKD stages,which is closely related to the deterioration of renal function. It can be used as a reference index to evaluate the incidence and severity of CKD.

Combination therapy of orally administered glycyrrhizin and UVB improved active-stage generalized vitiligo

Glycyrrhizin has been used clinically for several years due to its beneficial effect on immunoglobulin E (IgE)-induced allergic diseases, alopecia areata and psoriasis. In this study, glycyrrhizin, ultraviolet B light (UVB) or a combination of both were used to treat active-stage generalized vitiligo. One hundred and forty-four patients between the ages of 3 and 48 years were divided into three groups: group A received oral compound glycyrrhizin (OCG); group B received UVB applications twice weekly, and group C received OCG+UVB. Follow-ups were performed at 2, 4, and 6 months after the treatment was initiated. The Vitiligo Area Scoring Index (VASI) and the Vitiligo Disease Activity (VIDA) instrument were used to assess the affected body surface, at each follow-up. Results showed that 77.1, 75.0 and 87.5% in groups A, B and C, respectively, presented repigmentation of lesions. Responsiveness to therapy seemed to be associated with lesion location and patient compliance. Adverse events were limited and transient. This study showed that, although the three treatment protocols had positive results, OCG and UVB combination therapy was the most effective and led to improvement in disease stage from active to stable.

Empeoramiento de la enfermedad de Parkinson y componentes de subtipo motor influencia la condición física / Agravo da doença de Parkinson e subtipo motor influencia componentes da capacidade física / Parkinson's disease severity and motor subtype influence physical capacity components

The severity of Parkinson's disease (PD) and PD's motor subtypes influence the components of physical capacity. The aim of this study was to investigate the impact of both PD severity and motor subtype in the performance of these components. Thirty-six PD patients were assigned into four groups: Tremor (TD) initial and TD mild, akinetic-rigid (AR) initial, and AR mild. Patients' strength, balance, coordination, mobility and aerobic capacity were evaluated and groups were compared using a two-way ANOVA (severity and subtype as factors). AR presents a poorer performance than TD in almost all tests. Also this performance was worsened with the advance of the disease in AR, contrary to TD. We conclude that AR and TD subgroups are different about their performance on physical capacity components, moreover, this performance worsens with the advance of the disease of the AR group, but not for TD.

A doença de Parkinson (DP) é caracterizada por diferentes subtipos motores e supõe-se que o desempenho dos componentes da capacidade física é influenciado por esses subtipos. O objetivo desse estudo foi investigar o impacto que a severidade e o subtipo da DP podem trazer sobre o desempenho dos componentes da capacidade física. Trinta e seis pacientes com DP foram distribuídos em quarto grupos: com dominância de tremor (TD) inicial e TD intermediário ou acinesia (AR) inicial e AR intermediário. A força, equilíbrio, coordenação, mobilidade e capacidade aeróbia foram avaliados. AR apresentou um pior desempenho que TD em nos testes. Esse desempenho foi pior com o aumento da severidade da doença em AR, mas não em TD. Conclui-se que os grupos AR e TD são diferentes em relação ao desempenho dos componentes da capacidade física, mas principalmente, esse desempenho piora com o avanço da doença em AR, mas não em TD.

La enfermedad de Parkinson (EP) se caracteriza por subtipos motor, y se supone que el rendimiento de los componentes físicos de capacidad es influenciada por aquellos subtipos. El objetivo de este estudio fue investigar el impacto tanto de la severidade y subtipo de la PD en el rendimiento de estos componentes. Treinta y seis pacientes con EP se distribuyeron en: Temblor (TD) inicial y TD suave, acinesia (AR) inicial y AR suave. Fuerza, equilibrio, coordinación, la movilidad y la capacidad aeróbica fueron evaluados. AR presenta un desempeño más pobre que TD en las pruebas. También este comportamiento se agravó con el avance de la enfermedad en AR, diferente que en TD. Como conclusión AR y TD son diferentes en respecto a su rendimiento en los componentes físicos de capacidad, pero sobre todo, esto empeora con el aumento de avance de la enfermedad en el grupo de AR, pero no en TD.
