Objective To investigate the safety of regular plasma donors aged 55 to 60,so as to provide reference for retention and recruitment of elderly plasma donors in China.Methods Plasma donors from 9 blood products manufacturing enterprises from 2018 to 2020 and the local general population were selected as the research objects.The total protein level,albumin and globulin ratio(ALB/GLB,A/G)and adverse reactions of plasma donation of regular plasma donors and local general population were retrospectively analyzed.Results The total protein level(g/L)and A/G of plasma donors aged 56 to 60 and the general population were 61.21±5.62 vs 60.04±6.93 and 1.610±0.299 vs 1.635±0.330,respectively,and the differences were statistically significant.The total protein level of regular plasma donors was higher than that of general popu-lation,but A/G was slightly lower than that of general population.From 2018 to 2020,there were a total of 23 056 302 plas-ma donations in 108 plasma stations,and adverse reactions occurred in 20 932 donations,with a total incidence of 0.09%,with no serious adverse reactions.Conclusion It is safe for regular plasma donors aged 55 to 60 to donate plasma,and the retention of them can alleviate the pressure of plasma supply.

Objective:To analyze the medication law of Professor Li Fazhi in the prescriptions for the treatment of cough; To explore his academic thoughts.Methods:Medical cases of Professor Li about the treatment for cough from January 1, 2015 to October 31, 2022 were collected. Excel2016 and R language 4.2.1 were used to conduct multidimensional analysis on property and taste, and meridians of drugs. High-frequency efficacy classification was explored through factor analysis, clustering analysis was conducted to distinguish drug groups, and time-lapse analysis on proportion and meridian was conducted on high-frequency drugs.Results:4 746 prescriptions involved 270 kinds of Chinese materia medica, with a total frequency of 57 700 times. The most common property and taste was warm, followed by cold. Warm medicines were mainly pungent warm and cold warm, and cold medicines were mainly pungent cold, sweet cold and bitter cold, and the main meridians were lung, spleen, stomach, and liver meridians. The top 35 kinds of Chinese materia medica with frequency could be clustered into 9 groups. Group 1: Perillae Fructus, Armeniacae Semen Amarum and Ephedrae Herba; group 2: Magnoliae Flosmagnoliae Flos, Cicadae Periostracum and Glycyrrhizae Radix et Rhizoma; group 3: Peucedani Radix, Platycodonis Radix, Mori Cortex, Schizonepetae Herba, Saposhnikoviae Radix and Farfarae Flos; group 4: Angelicae Dahuricae Radix, Notopterygii Rhizoma et Radix, Citri Reticulatae Pericarpium, Astragali Radix, Cimicifugae Rhizoma and Coptidis Rhizoma; group 5: Coicis Semen, Phragmitis Rhizoma, Persicae Semen and Benincasae Semen; group 6: Perillae Folium; group 7: Bupleuri Radix, Mume Fructus, Aurantii Fructus Immaturus, Scutellariae Radix and Paeoniae Radix Alba; group 8: Asari Radix et Rhizoma, Cinnamomi Ramulus, Zingiberis Rhizoma, Schisandrae Chinensis Fructus and Pinelliae Rhizoma Praeparatum cum Alumine; group 9: Poria and Glycyrrhizae Radix et Rhizoma Praeparata cum Melle. The time-lapse analysis showed that the proportion of drugs used in the past three years such as Glycyrrhizae Radix et Rhizoma Praeparata cum Melle, Poria and Aurantii Fructus was gradually increasing.Conclusions:Professor Li's treatment of cough focuses on the lungs, spleen, and stomach. Clinical medication emphasizes the combination of ascending and descending factors, as well as the use of cold and warm. In recent years, there has been a greater emphasis on treating cough from the middle energizer.

Primary angle-closure glaucoma (PACG) is still one of the common blinding eye diseases in China.Because of the irreversibility of the vision loss it caused, the factors affecting the early development of glaucoma are of great concern.The understanding of static anatomic structure of high-risk anterior segment, such as shallow anterior chamber, short axial length, thick iris and large anterior lens cannot fully explain the transformation process of PACG, so the specific role of dynamic changes in the development of glaucoma should be further considered.This article expounded the differences in iris volume and dynamic process of elasticity between normal people and patients with PACG, the incoordination between lens and intraocular structure during eyeball development, the dynamic block and expansion of ciliary body, vitreous and choroid, and the latest research on the relationship between the abnormal ocular nerve and vascular system adjustment and change with the onset of PACG, in order to provide guidance for understanding the pathogenesis of PACG, accurate clinical diagnosis and formulation of treatment strategies.

Autoimmune hepatitis (AIH) is an immune-mediated liver disease with hepatocytes as the main target cells. It is characterized by the high immunoglobulin G level and the presence of autoantibodies, and histological observation shows interface hepatitis at the portal area caused by a large amount of lymphoplasmacytic infiltration. The pathogenesis of AIH has not been fully elucidated. At present, glucocorticoid combined with azathioprine is mainly used as non-specific immunosuppressive therapy, and most patients tend to have good response; however, rebound or relapse is often observed during dose reduction or after drug withdrawal, so most patients need long-term maintenance therapy. This article briefly reviews the advances in the pathogenesis of AIH and the potential new targets for clinical intervention, in order to provide a reference for clinical translational research.

Objective:To investigate the effect of psychological support during perithrombotic period on post-stroke depression (PSD) in patients with acute ischemic stroke (AIS).Methods:Patients with AIS received intravenous thrombolysis in the Affiliated Lianyungang Hospital of Xuzhou Medical University from January 1, 2021 to July 31, 2021 were enrolled prospectively. The intervention group received one-to-one individual psychological support therapy in the perithrombolytic period on the basis of receiving standard intravenous thrombolytic therapy. At 30 d after onset, Hamilton Depression Scale was used to assess whether PSD occurred. Multivariate logistic regression analysis was used to evaluate the independent influencing factor of PSD. Results:A total of 126 patients with AIS were enrolled, and 86 of them were male (68.25%). Their age was 63.65±10.46 years; 65 were in the intervention group and 61 were in the control group. The incidence of PSD in the intervention group was significantly lower than that in the control group (20.00% vs. 36.07%; χ2=4.049, P=0.044). Multivariate logistic regression analysis showed that psychological intervention (odds ratio [ OR] 0.333, 95% confidence interval [ CI] 0.132-0.838; P=0.020] was an independent protective factor for PSD, while ischemic heart disease ( OR 4.510, 95% CI 1.181-17.217; P=0.028), alcohol consumption ( OR 3.421, 95% CI 1.317-8.888; P=0.012), anticoagulation therapy ( OR 3.145, 95% CI 1.155-8.567; P=0.025) and modified Rankin Scale score before thrombolysis ( OR 1.627, 95% CI 1.142-2.317; P=0.007) were the independent risk factors for PSD. Conclusion:Perithrombolytic psychological support may reduce the incidence of PSD.

Primary biliary cholangitis (PBC) is an autoimmune-mediated chronic cholestatic liver disease, with the typical biochemical manifestation of significantly elevated alkaline phosphatase (ALP) and gamma-glutamyl transpeptidase (GGT), with or without mild-to-moderate elevation of aminotransferases. ALP and GGT play an important role in the diagnosis and monitoring of PBC. With a deeper understanding of PBC, the significance of elevated aminotransferases in diagnosis and treatment has attracted more and more attention. This article briefly summarizes the significance of elevation of aminotransferases in PBC patients.

Objective To identify the risk factors for postoperative short-term cognitive dysfunction ( STCD) in the patients undergoing carotid endarterectomy. Methods A total of 158 patients with carotid artery stenosis, aged≥18 yr, without preoperative cognitive dysfunction, undergoing carotid endarterecto-my from January 1, 2014 to May 30, 2017 in our hospital, were selected. Factors including age, sex, height, weight, education, presurgical complications ( hypertension, type Ⅱ diabetes mellitus, myocar-dial infarction and brain infarction) , degree of internal carotid artery stenosis, preoperative mean arterial pressure ( MAP ) , amount of dexmedetomidine, duration of operation, time of carotid artery occlusion, MAP during occlusion period, intraoperative volume of fluid infused ( crystalloid solution and colloid solu-tion), urine volume, blood loss, significant change in electroencephalogram (EEG) and visual analogue scale scores at 24 h after surgery were collected. Mini-Mental State Examination was used to evaluate the cognitive function at 24 h after surgery. The patients were divided into STCD group and non-STCD group ac-cording to whether or not patients developed postoperative STCD. The risk factors of which P values were less than 0. 05 would enter the bivariate logistic regression analysis to stratify the risk factors for postopera-tive STCD. Results Forty-nine patients developed postoperative STCD ( 31. 0％) . The intraoperative a-mount of colloid solution infused＜5 ml/kg, increase in MAP＜20％ of the baseline value during the occlu-sion period, and significant change in EEG during the occlusion period were independent risk factors for postoperative STCD ( P＜0. 05) . Conclusion The intraoperative amount of colloid solution infused＜5 ml/kg, increase in MAP＜20％ of the baseline value during the occlusion period, and significant change in EEG during the occlusion period are independent risk factors for postoperative STCD in the patients undergo-ing carotid endarterectomy.

Substantial evidence supports the neurodevelopmental hypothesis of schizophrenia. Meanwhile, progressive neurodegenerative processes have also been reported, leading to the hypothesis that neurodegeneration is a characteristic component in the neuropathology of schizophrenia. However, a major challenge for the neurodegenerative hypothesis is that antipsychotic drugs used by patients have profound impact on brain structures. To clarify this potential confounding factor, we measured the cortical thickness across the whole brain using high-resolution T1-weighted magnetic resonance imaging in 145 first-episode and treatment-naïve patients with schizophrenia and 147 healthy controls. The results showed that, in the patient group, the frontal, temporal, parietal, and cingulate gyri displayed a significant age-related reduction of cortical thickness. In the control group, age-related cortical thickness reduction was mostly located in the frontal, temporal, and cingulate gyri, albeit to a lesser extent. Importantly, relative to healthy controls, patients exhibited a significantly smaller age-related cortical thickness in the anterior cingulate, inferior temporal, and insular gyri in the right hemisphere. These results provide evidence supporting the existence of neurodegenerative processes in schizophrenia and suggest that these processes already occur in the early stage of the illness.

ObjectiveTo explore the correlation between post-traumatic stress disorder(PTSD) and emotional regulation in the parents whose children have acute lymphoblastic leukemia(ALL). MethodsBy convenient sampling method, a total of 233 parents whose children had ALL were selected in the First Affiliated Hospital of Zhengzhou University from June 2013 to June 2017, and the levels of PTSD and emotional regulation were evaluated by The PTSD Checklist-Civilian Version (PCL-C) and Emotion Regulation Questionnaire(ERQ). A total of 233 questionnaires were distributed and 233 valid ones were retrieved, yielding an effective recovery rate of 100%. ResultsIn this study, the participants got (35.82±4.93) points for PCL-C, among which the highest average item score was (2.29±0.36) points for "Avoid/Numb"; the score of "cognitive reappraisal" and"expressive suppression" were (4.27±0.64) and (4.35±0.60) points in ERQ. Pearson correlation analysis showed that the total score and each dimension score in PCL-C were negatively correlated with cognitive reappraisal (P＜0.05), and were positively correlated with expressive suppression (P＜0.05). Multivariate linear regression analysis showed that cognitive reappraisal and expressive suppression were the influencing factors for PTSD of the parents with ALL children (P＜0.05). ConclusionsALL children's parents have serious PTSD and tend to choose the emotional regulation way of expressive suppression. There is correlation between the degree of PTSD in ALL children's parents and their emotional regulating ability, therefore, nursing staff should assist them in the improvement of their emotional regulation ability to reduce the level of PTSD.
