Research Advance of Chinese Medicine in Treating Atherosclerosis: Focus on Lipoprotein-Associated Phospholipase A2 / 中国结合医学杂志

As a serious cardiovascular disease, atherosclerosis (AS) causes chronic inflammation and oxidative stress in the body and poses a threat to human health. Lipoprotein-associated phospholipase A2 (Lp-PLA2) is a member of the phospholipase A2 (PLA2) family, and its elevated levels have been shown to contribute to AS. Lp-PLA2 is closely related to a variety of lipoproteins, and its role in promoting inflammatory responses and oxidative stress in AS is mainly achieved by hydrolyzing oxidized phosphatidylcholine (oxPC) to produce lysophosphatidylcholine (lysoPC). Moreover, macrophage apoptosis within plaque is promoted by localized Lp-PLA2 which also promotes plaque instability. This paper reviews those researches of Chinese medicine in treating AS via reducing Lp-PLA2 levels to guide future experimental studies and clinical applications related to AS.

Historical evolution and clinical application of classical prescription Yigongsan / 中国药房

Yigongsan， derived from QIAN Yi’s Key to Therapeutics of Children’s Diseases in the Song Dynasty， is a classic pediatric prescription that is included in the Catalogue of Ancient Classic Prescriptions （the Second Batch of Pediatrics） released by the National Administration of Traditional Chinese Medicine in 2022. This paper verifies and analyzes the historical origin， composition， dosage， processing， decoction method and efficacy of Yigongsan by systematically combing ancient books and modern documents. As a result， Yigongsan is composed of five herbs： Panax ginseng， Poria cocos， Atractylodes macrocephala， Citrus reticulata and Glycyrrhiza uralensis， of which P. cocos should be peeled， A. macrocephala is fried with soil， G. uralensis is roasted with honey while P. ginseng and C. reticulata are raw products. According to the dosage of ancient and modern times， each medicinal herb must be ground into fine powder， 1.6 g for each， added with 300 mL of water， 5 pieces of Zingiber officinale， and 2 Ziziphus jujuba， decocted together to 210 mL， and taken before meals. In ancient books， Yigongsan is used to treat vomiting， diarrhea， spleen and stomach deficiency， chest and abdominal distension， and lack of appetite， etc. Modern research showed that Yigongsan could also be used in the diseases of immune system， respiratory system， blood system， etc.， involving infantile anorexia， asthma， anemia， tumors and so on.

The Role of SDF-1α-CXCR4/CXCR7 in Migration of Human Periodontal Ligament Stem Cells

Background and Objectives@#Regenerative endodontic procedures (REPs) are a research hotspot in the endodontic field. One of the biggest problems of REPs is that it is difficult to realize regeneration of pulp-dentin complex and functional reconstruction. The reason is still not clear. We hypothesize that the migration may be different in different dental stem cells. Periodontal ligament stem cells (PDLSCs) may migrate faster than stem cells of apical papilla (SCAPs), differentiating into cementum-like tissue, bone-like tissue and periodontal ligament-like tissue and, finally affecting the outcomes of REPs. Hence, this study aimed to explore the mechanism that regulates the migration of PDLSCs. @*Methods@#and Results: After isolating and culturing PDLSCs and SCAPs from human third molars, we compared the migration of PDLSCs and SCAPs. Then we investigated the role of SDF-1α-CXCR4/CXCR7 axis in PDLSC migration. We further investigated the impact of Porphyromonas gingivalis (P. gingivalis) lipopolysaccharide (LPS) on PDLSC migration and the potential mechanism. PDLSCs showed better migration under both noninflammatory and inflammatory conditions than SCAPs. SDF-1α can promote the migration of PDLSCs by elevating the expression of CXCR4 and CXCR7, increasing the interaction between them, promoting expression of β-arrestin1 and activating the ERK signaling pathway. P. gingivalis LPS can promote the migration of PDLSCs toward SDF-1α through increasing the expression of CXCR4 via the NF-κB signaling pathway, promoting the expression of β-arrestin1, and activating the ERK signaling pathway. @*Conclusions@#This study helped elucidate the potential reason for the difficulty in forming pulp-dentin complex.

AIM: To investigate the efficacy and safety of orthokeratology combined with 0.01% atropine solution in adolescents with myopia.METHODS: A total of 100 adolescent myopic patients(100 right eyes)who received treatment at the Department of Ophthalmology, People's Hospital of Hengshui from January 2019 to January 2022 were enrolled. All patients were divided into two groups based on the patient's preferences and randomized controlled principles: control group(n=50)and experimental group(n=50). Patients in the control group received orthokeratology alone, while those in the experimental group received orthokeratology in combination with 0.01% atropine solution. Treatment data for both groups were collected at 1, 3, 6, 9 and 12mo after treatment. The observed indicators included refraction, corneal curvature, axial length(AL), central corneal thickness(CCT), pupil diameter(PD), lipid layer thickness(LLT), break-up Time(BUT), root-mean-square of higher-order aberration(RMSh), subfoveal choroidal thickness(SFCT), corneal endothelial cell density(CD), and hexagonal cell ratio(HEX). The adverse reactions experienced during follow-up period were also observed and recorded.RESULTS: After 12mo of treatment, the refraction, corneal curvature, and AL in the experimental group were -2.42±0.17D, 38.89±1.18D and 25.44±0.23mm, respectively, which were significantly better than the control group(-2.56±0.19D, 40.12±1.65D and 25.54±0.19 mm, all P<0.05). The CCT of the experimental group(538±33 μm)was lower than that of the control group(545±41 μm), while the PD of the experimental group was higher than that of the control group(6.38±0.38 mm vs. 6.12±0.37 mm, P<0.05). LLT and BUT in the experimental group was 61.14±8.41 nm and 9.24±2.05s, respectively, which were significantly higher than those in the control group(56.14±7.22 nm and 7.27±1.99s, all P<0.05). RMSh in the experimental group was lower than that of the control group(0.73±0.21 μm vs. 0.85±0.12 μm, P<0.05), and SFCT in the experimental group was significantly higher than that of the control group(289±55 μm vs. 282±59 μm, P<0.05). Additionally, after 12mo of treatment, there was no significant difference in CD and HEX between the experimental group and the control group(all P>0.05). The main adverse reactions of both groups during treatment period were photophobia, anaphylaxis, conjunctivitis and keratitis, but there was no significant difference between the two groups(all P>0.05).CONCLUSION: Compared to orthokeratology alone, the combination of orthokeratology and 0.01% atropine solution effectively prevents and improves the development of adolescent myopia without increasing the incidence of adverse reactions.

Objective:To explore the clinical significance of hepatitis B virus (HBV) DNA detection in screening patients with hepatitis B.Methods:Clinical data of 682 331 hepatitis B patients were retrospectively analyzed. The HBV DNA of these patients was detected in the Fifth Medical Center of the PLA General Hospital from January 2017 to December 2021, there were 481 159 males and 201 172 females in this cohort, the average age was (41.34±16.13) years. Patients were divided into HBV DNA positive group (219 879 cases) and HBV DNA negative group (462 452 cases). Clinical characteristics, data of five serologic markers of hepatitis B and hepatitis B surface antigen quantification (HBsAg-QN), liver function, alpha fetoprotein (AFP) and prothrombin time (PT) results were collected and analyzed and compared between the two groups.Results:The positive rate of HBV DNA was 32.22% (219 879/682 331) in this cohort. Among the different age groups, the positive rate of HBV DNA was the highest (40.34%, 128 038/317 380) in young people aged 18-44 years. The proportion of patients was lower among aged <1, 45-59 and ≥60 years patients in HBV DNA positive group than that in HBV DNA negative group, while the proportion of patients was higher among aged 1-17 and 18-44 years patients in HBV DNA positive group than that in HBV DNA negative group (all P<0.001). Among 2 291 <1-year-old infants tested for HBV DNA, 71 infants were HBV DNA positive. The positive rates of HBV DNA from 2017 to 2021 were 4.86% (27/556), 3.68% (14/380), 3.47% (17/490), 1.55% (6/386) and 1.46% (7/479) respectively, showing a downward trend year by year. The positive rate of HBV DNA in acute hepatitis B (AHB) patients was the highest (49.88%, 208/417) among 680 040 patients with hepatitis B. The proportion of AHB patients (0.09%, 208/219 808) and chronic hepatitis B (80.44%, 176 806/219 808) in HBV DNA positive group was higher than that in HBV DNA negative group [0.05% (209/460 232) and 65.45% (301, 216/460 232)], while the proportion of patients with HBV-related liver cirrhosis (11.28%, 24 793/219 808), HBV-related liver cancer (6.72%, 14 775/219 808), liver cancer surgery (1.39%, 3 055/219 808) and liver transplantation (0.08%, 171/219 808) were lower than that in HBV DNA negative group [22.99% (105 813/460 232), 7.25% (33 385/460 232), 3.50% (16 129/460 232) and 0.76% (3 480/460 232)] (all P<0.001). At the same time, positive rate of hepatitis B surface antigen (HbsAg), HBsAg-QN, hepatitis B e antigen (HbeAg), level of total bilirubin, total bilirubin, AFP and PT were higher in HBV DNA positive group than those in HBV DNA negative group, while the age, male ratio and albumin results in HBV DNA positive group were lower than those in HBV DNA negative group (all P<0.01). The HBV DNA loads were higher in HBsAg positive group, hepatitis B surface antibody positive group and HBeAg positive group than those in respective negative groups, while the HBV DNA loads were lower in hepatitis B e antibody positive group and hepatitis B core antibody positive group than those in respective negative groups (all P<0.001). Conclusions:The mother to child transmission rate of<1-year-old infants decreases year by year. HBV DNA is an important factor for the progression of hepatitis B disease. HBV DNA positive hepatitis B patients with higher HBsAg-QN values are more likely to have abnormal serum markers such as liver dysfunction. HBV DNA detection is therefore of clinical importance in screening patients with hepatitis B.

Research progress on characteristics of aortic dissection related metabolomics / 中华全科医师杂志

Aortic dissection (AD) is a life-threatening vascular disease due to the tearing of aortic intimal layer, leading to the formation of pseudocavity. Once the acute progression of dissection happens, serious complications such as rupture and stroke may occur. The current imaging examinations for AD are invasive and may cause adverse effects related to contrast medium, which cannot be used for large-scale screening of AD. The latest studies have found that metabolic processes and metabolites of lipids,saccarides and proteins are involved in the pathogenesis and development of AD. In this article, we review the research progress in the caracteristics of AD related metabolism,summarize changes of specific metabolites in AD,and explore the clinical implication of studies on AD related metaboliome..

Application of 18F-FDG PET in the diagnosis and evaluation of SARS-CoV-2 infection and related events / 中华核医学与分子影像杂志

Coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has rapidly ravaged the world and infected hundreds of millions of people since its outbreak. Early diagnosis of COVID-19 is conducive to the control of virus transmission and the timely treatment of patients. Among the imaging techniques, chest CT is an important basis for the diagnosis and evaluation of COVID-19. 18F-FDG PET is not generally recommended as a routine diagnostic tool for COVID-19, but it plays an important role in the assessment of SARS-CoV-2-related events based on the characteristic of whole-body multi-systemic scan and functional imaging diagnosis. In this paper, the application of 18F-FDG PET in COVID-19 diagnosis, prognostic evaluation and long-term sequelae evaluation, and clinical performance of 18F-FDG PET after COVID-19 vaccine are summarized on the basis of literature research and clinical reports analysis. Furthermore, the application and development direction of other new molecular probes for nuclear medicine in COVID-19 are prospected.

Tetrahydroxy stilbene glycoside ameliorates neuroin-flammation for Alzheimer's disease via cGAS-STING / 中国药理学与毒理学杂志

OBJECTIVE Alzheimer's disease(AD)is the most common neurodegenerative disease worldwide.Neuroinflammation is a potential target for the patients with AD.It is attributed to activated microglia and the release of various inflammatory mediators from infec-tion,ischemia and toxin accumulation.Accumulating evi-dence has indicated that the cGAS-STING pathway driven neuroinflammation in neurological disease.TSG is a main natural active ingredient that derived from polyg-onum multiflorum.Previous research from our group found that TSG has beneficial effects of anti-aging,anti-inflammatory action and improving memory function in APP/PS1 transgenic AD mice.Here,we investigated the effects of TSG on cognitive impairment and neuroinflam-mation in APP/PS1-AD mice and explore the underly-ing mechanism by which TSG ameliorates memory func-tion in the cGAS-STING-mediated inflammatory response.METHODS The Morris water mace test and the novel object recognition test were performed to test the effects of TSG on spatial learning and cognitive and memory abil-ity in APP/PS1 double transgenic AD mice model.In addi-tion,real-time quantitative PCR,Western blotting,ELISA analysis,and flow cytometry to examine gene and pro-tein expression of cGAS-STING related pro-inflammatory cytokines and chemokines.Statistical analyses were ana-lyzed using the SPSS 25.0 package by analysis of vari-ance(ANOVA).Neuman-Keuls or Tukey's multiple-com-parisons test were conducted as ANOVA justified post hoc comparisons between group means.RESULTS We demonstrated that AD transgenic mice exhibited cognitive deficits accompanied by the elevated serum and brain inflammation.The expressions of serum inflammatory cytokines and the activation of microglia in cerebral cor-tex and hippocampus were suppressed after TSG treat-ment,which was probably attributable to the decrease of cyclic GMP-AMP synthase(cGAS)and stimulator of interferon genes(STING)triggered immune response.Additionally,the data showed that TSG treatment reduced the expression level of inflammatory cytokines(IL-1β,TNF-α,IFN-β,IFN-α)in microglial cells BV2 primed with LPS and IFN-γ.CONCLUSION TSG implicated the health benefits in preventing cognitive disorders by inhib-iting neuroinflammation via cGAS-STING signalling path-way in AD.

Cornel iridoid glycoside alleviates microglia-mediated inflammatory response via NLRP3/calpain pathway / 中国药理学与毒理学杂志

OBJECTIVE Vascular dementia(VaD)is associated with cerebral hypoperfusion,which results in long-term cognitive impairment and memory loss.Neuroin-flammation is an important mechanism of vascular demen-tia.Cornel iridoid glycoside(CIG)is the major active con-stituent isolated from the ripe fruit of Cornus officinalis.Previous studies have shown that CIG enhances neuro-logical function in VaD rats.In the present research,we attempted to clarify the molecular processes underlying the role of CIG on neuroinflammation in VaD.METHODS In vivo,we created a chronic cerebral ischemia rat model by ligation of the bilateral common carotid arteries(2VO).The rats were divided into sham operation,2VO,2VO + CIG(60 and120 mg·kg-1·d-1),and 2VO+ butylphthalide(100 mg·kg-1·d-1)groups and then treated rats with differ-ent concentrations of CIG.In vitro,BV2 microglia cells were induced with bacterial lipopolysaccharide(LPS)and interferon-γ(IFN-γ)to construct the model of microglias with analog neuroinflammation.Histopathology and biel-schowsky silver staining were used to detect myelin integrity and neuronal loss.Immunofluorescence was used to observe changes in microglia.Magnetic Luminex Assay was used to detect changes in inflammatory fac-tors.Western blotting,ELISA or calpain activity assay was used to measure the expression and activity of cal-pain,as well as the expression of NLRP3 inflammasome protein.Furthermore,NLRP3 overexpressing cells were used to further elucidate the potential anti-inflammatory molecular mechanism of CIG.RESULTS ① CIG improved neuronal impairment in the brain of 2VO rats.②CIG increased white matter(WM)integrity in 2VO rats.③ CIG reduced microglia inflammatory response in the cortex and hippocampus of 2VO rats.④ CIG inhibited calpain activity in the cortex and hippocampus of 2VO rats.⑤ CIG exerted anti-inflammatory effects on BV2 cells stimulated by LPS and IFN-γ.⑥ CIG Inhibited the expression and activity of calpain in LPS/IFN-γ-activated BV2 cells.⑦ The main component of CIG had a weak binding force to calpain1.⑧ CIG inhibited the activation of the NLRP3 inflammasome.⑨CIG reduced the activity of calpain induced by NLRP3 overexpression.CONCLU-SION CIG inhibits microglial polarization into a proinflam-matory state by attenuating the assembly of the NLRP3 inflammasome and calpain activation,thus reducing brain inflammation,WM injury,and the loss of neurons.To sum up,the present study suggests that CIG inhibits neuroinflammation.The NLRP3/calpain pathway may be the main pathway by which CIG protects against neuroin-flammation.

Vascular endothelial cell dysfunction and Alzheimer's disease / 中国药理学与毒理学杂志

Alzheimer's disease(AD)is a neurode-generative disease with complex pathological mecha-nism characterized by accumulation of amyloid plaques and neurofibrillary tangles in the brain.Increasing evi-dence suggests that vascular dysfunction due to endothe-lial cell injury may have a pathogenic role in the occur-rence and development of AD.Malfunction of the blood-brain barrier caused by endothelial cell dysfunction is associated with the accumulation of several neurotoxic molecules within brain parenchyma,a reduction in cerebral blood flow,amyloid-β transfer and hypoxia,especially at the early stages of the disease.At the same time,it can-not be ignored that the peripheral arterial vascular endo-thelial cell dysfunction also seems to be closely related to the risk and the severity of symptoms of AD.Some mole-cules are thought to be messengers connecting the central and peripheral endothelial cells.Peripheral and central vascular endothelial cells communicate with each other and influence the progression of AD through some common mechanisms.In this review,we provide an ap-praisal of the endothelial cell dysfunction in cerebral and systemic vasculature,and give the evidence that vascular pathology is inextricably linked to disease onset and pro-gression of AD.

Regulation of Mitochondrial Quality Control in Treatment of Diabetic Kidney Disease by Traditional Chinese Medicine： A Review / 中国实验方剂学杂志

Diabetic kidney disease （DKD） is characterized by the hyperfiltration and albuminuria in the early phase which are followed by progressive renal function decline， renal tubular epithelial cell hypertrophy， and tubulointerstitial fibrosis. Thus， it is one of the leading causes of chronic kidney diseases. The currently available therapies mainly aim to control the primary diseases and reduce the risk of kidney injury. Based on syndrome differentiation， traditional Chinese medicine （TCM） relieves the symptoms by excreting water and alleviating edema and eliminates the root cause by tonifying deficiency and supplementing the original Qi， thereby showing therapeutic effect and delaying the progression of DKD. It excels in comprehensively regulating the constitution of patients with little side effects. Among the Zang-fu organs， kidney takes the second place in the content of mitochondria which participate in the metabolism of water and fluid and are the foundation of kidney Yin and kidney Yang. Mitochondria are energy producers within a cell， which carry out cellular respiration， produce reactive oxygen species， and generate adenosine triphosphate by oxidative phosphorylation. Mitochondrial quality control （MQC） is an effective way to maintain mitochondrial dynamic balance， whose imbalances， such as mitochondrial oxidative stress， mitophagy， mitochondrial dynamic changes， and abnormal calcium regulation， are related to the occurrence and development of DKD. It is generally believed that the destruction of mitochondrial structure in the case of metabolic disorder is the main cause of the disease. In recent years， TCM has attracted the attention of both Chinese and foreign researchers for the unique advantages of treating both symptoms and root cause at the same time and multi-target synergy in the treatment of DKD. However， the specific mechanism is still unclear. It has been frequently verified that mitochondria may be one of the targets of TCM in the treatment of DKD. At the moment， no review on the treatment of DKD by TCM through the intervention of MQC is available. Therefore， this paper aims to summarize the research on TCM treatment of DKD by regulating MQC in the past 10 years， which is expected to provide a new direction for the treatment of DKD by TCM.

Efficacy differences between electroacupuncture and moxibustion for neurogenic bladder after spinal cord injury: a randomized controlled trial / 中国针灸

OBJECTIVE@#To compare the clinical efficacy between electroacupuncture(EA) and moxibustion for neurogenic bladder (NB) after spinal cord injury (SCI).@*METHODS@#One hundred and twenty patients with NB after SCI were randomly divided into an EA group, a moxibustion group, and an intermittent catheterization group, with 40 patients in each group. The patients in the intermittent catheterization group were treated with routine treatment and intermittent catheterization, while the patients in the EA group and the moxibustion group were treated with additional treatments of EA (discontinuous wave, with a frequency of 1.3-1.6 Hz, and intensity based on patient tolerance) and moxibustion, respectively. The acupoints used in both groups were Zhongji (CV 3) and Guanyuan (CV 4), bilateral Zusanli (ST 36), Yinlingquan (SP 9), and Baliao points. Each session lasted for 30 min, once daily, six times a week, for a total of six weeks.The maximum bladder capacity (MBC), residual urine vdume (RUV), detrusor pressure (Pdet) during the filling phase, bladder compliance (BC), maximum renal pelvis separation width of both kidneys, urine white blood cell count, TCM syndrome score, and World Health Organization quality of life assessment-BREF (WHOQOL-BREF) score were compared before and after treatment in the 3 groups. The number of patients in each group who achieved bladder functional balance was recorded, and the clinical efficacy was assessed after treatment.@*RESULTS@#After treatment, the MBC, Pdet, BC, and WHOQOL-BREF scores in the EA group and the moxibustion group were increased (P<0.05), while the RUV, maximum renal pelvis separation width of both kidneys, urine white blood cell count, and TCM syndrome scores were decreased (P<0.05, P<0.01). In the intermittent catheterization group, MBC, RUV, maximum renal pelvis separation width of both kidneys, and urine white blood cell count were decreased (P<0.05), while BC and WHOQOL-BREF score were increased (P<0.05) after treatment. After treatment, the MBC, Pdet, BC, and WHOQOL-BREF scores in the EA group and the moxibustion group were higher than those in the intermittent catheterization group (P<0.05), while the RUV and TCM syndrome scores were lower than those in the intermittent catheterization group (P<0.05). Moreover, after treatment, the MBC and Pdet in the moxibustion group were higher than those in the EA group (P<0.05), while the RUV, maximum renal pelvis separation width of both kidneys, and TCM syndrome score in the EA group were lower than those in the moxibustion group (P<0.05). The number of patients who achieved bladder functional balance after treatment in the EA group and the moxibustion group was higher than that in the intermittent catheterization group (P<0.05). The cured and effective rate was 85.0% (34/40) in the EA group and 82.5% (33/40) in the moxibustion group, which were both higher than 65.0% (26/40) in the intermittent catheterization group (P<0.05), there was no significant difference between the EA group and the moxibustion group (P>0.05).@*CONCLUSION@#EA and moxibustion could effectively improve the functional state of bladder in patients with NB after SCI. EA is more effective in reducing residual urine volume and excessive activity of the urethral sphincter, and relieving TCM syndromes, while moxibustion is more effective in increasing the pressure of the detrusor during the filling period and establishing the detrusor reflex.

Distribution of traditional Chinese medicine syndrome types and elements in liver cirrhosis patients with dysplastic nodules: An analysis of 138 cases / 临床肝胆病杂志

Objective To investigate the distribution of traditional Chinese medicine (TCM) syndrome types and elements in liver cirrhosis patients with dysplastic nodules (DN), and to provide a basis for exploring the connotation and pattern of TCM syndrome types of DN in liver cirrhosis. Methods A total of 138 patients who attended The First Affiliated Hospital of Henan University of Chinese Medicine from March 2013 to January 2021 and were diagnosed with liver cirrhosis and DN were enrolled. General data such as age of onset and sex were collected, as well as the data on etiology, TCM syndrome types, and Child-Pugh class for liver function, and the distribution characteristics of TCM syndrome types and elements were summarized. The chi-square test or the Fisher's exact test was used for comparison of categorical data between groups. Results The liver and the spleen were the main syndrome elements of disease location in liver cirrhosis patients with DN, accounting for 97.83% and 94.93%, respectively, followed by the kidney (23.91%); Qi deficiency and Qi stagnation were the main syndrome elements reflecting the nature of disease, accounting for 73.91% and 58.70%, respectively, followed by dampness (34.78%). The main TCM syndrome types included stagnation of liver Qi and spleen deficiency, damp-heat internal excess syndrome, blood stasis and toxin accumulation syndrome, and water-dampness retention syndrome, among which stagnation of liver Qi and spleen deficiency was more common and accounted for 58.70% ( P 0.05). There was a significant difference in Child-Pugh class between the liver cirrhosis DN patients with different TCM syndrome types ( χ 2 =34.320, P < 0.05), and Child-Pugh class A was more common in the patients with stagnation of liver Qi and spleen deficiency (59.8%), while Child-Pugh class C was more common in the patients with damp-heat internal excess syndrome (39.1%). Conclusion This article summarizes the distribution characteristics of common TCM syndrome types and elements of DN in liver cirrhosis, which provides a reference for the syndrome differentiation-based TCM treatment of DN in liver cirrhosis.

Free sialic acid storage disorders with fetal hydrops in a neonate / 中国当代儿科杂志

A boy, aged 3 hours, was admitted due to a prenatal diagnosis of fetal hydrops at 3 hours after resuscitation for birth asphyxia. Prenatal examination at 5 months of gestation showed massive ascites in the fetus, and after birth, the boy had the manifestations of systemic hydroderma, massive ascites, coarse face, and hepatomegaly. Genetic testing revealed heterozygous mutations in the SLC17A5 gene, and there was a significant increase in urinary free sialic acid. Placental pathology showed extensive vacuolization in villous stromal cells, Hofbauer cells, cytotrophoblast cells, and syncytiotrophoblast cells in human placental chorionic villi. The boy was finally diagnosed with free sialic acid storage disorders (FSASDs). This is the first case of FSASDs with the initial symptom of fetal hydrops reported in China. The possibility of FSASDs should be considered for cases with non-immune hydrops fetalis, and examinations such as placental pathology and urinary free sialic acid may help with early diagnosis and clinical decision making.

Effects of intranasal administration of tripterygium glycoside-bearing liposomes on behavioral cognitive impairment of mice induced by central nervous system inflammation / 中国中药杂志

Tripterygium glycosides liposome(TPGL) were prepared by thin film-dispersion method, which were optimized accor-ding to their morphological structures, average particle size and encapsulation rate. The measured particle size was(137.39±2.28) nm, and the encapsulation rate was 88.33%±1.82%. The mouse model of central nervous system inflammation was established by stereotaxic injection of lipopolysaccharide(LPS). TPGL and tripterygium glycosides(TPG) were administered intranasally for 21 days. The effects of intranasal administration of TPG and TPGL on behavioral cognitive impairment of mice due to LPS-induced central ner-vous system inflammation were estimated by animal behavioral tests, hematoxylin-eosin(HE) staining of hippocampus, real-time quantitative polymerase chain reaction(RT-qPCR) and immunofluorescence. Compared with TPG, TPGL caused less damage to the nasal mucosa, olfactory bulb, liver and kidney of mice administered intranasally. The behavioral performance of treated mice was significantly improved in water maze, Y maze and nesting experiment. Neuronal cell damage was reduced, and the expression levels of inflammation and apoptosis related genes [tumor necrosis factor-α(TNF-α), interleukin-1β(IL-1β), BCL2-associated X(Bax), etc.] and glial activation markers [ionized calcium binding adaptor molecule 1(IBA1) and glial fibrillary acidic protein(GFAP)] were decreased. These results indicated that liposome technique combined with nasal delivery alleviated the toxic side effects of TPG, and also significantly ameliorated the cognitive impairment of mice induced by central nervous system inflammation.
