Shengyutang is a famous classical formula of tonic， which is made from Siwutang with Ginseng Radix et Rhizoma and Astragali Radix. It is included in the Catalogue of Ancient Famous Classical Formulas（The First Batch）. Based on the Principles of Key Information Research of Ancient Famous Classical Formulas， this paper used bibliometrics to sort out and research the key information of Shengyutang in the aspects of history， composition， origin and processing， dosage， decocting method， efficacy and indications. After research， it has been found that this formula was first recorded in Lanshi Micang written by LI Dongyuan during the Jin dynasty， composed of Rehmanniae Radix， Rehmanniae Radix Praeparata， Chuanxiong Rhizoma， Ginseng Radix et Rhizoma， Astragali Radix and Angelicae Sinensis taproot. The name of the formula passed down through generations was relatively unified， with clear origins and veins. In later generations， this formula was the mainstream， and adjustments were made to the dosage and composition according to the indication. In the formula， Astragalus membranaceus var. mongholicus was selected as the origin of Astragali Radix， and the origins of other medicinal materials were consistent with the 2020 edition of Chinese Pharmacopoeia. Except for Rehmanniae Radix Praeparata， the other medicinal materials were made from raw products， and the dosage form was boiled powder. According to the measurement standard in the Jin dynasty， the recommended usage and dosage were 1.24 g of Rehmanniae Radix， Rehmanniae Radix Praeparata， Chuanxiong Rhizoma， Ginseng Radix et Rhizoma each， 2.07 g of Astragali Radix and Angelicae Sinensis taproot each， crushed into coarse particles that pass through the 4 mesh sieve but can't pass through the 10 mesh sieve， added 1 200 mL of water and boiled to 300 mL， and removed the residue. Shengyutang has the functions of tonifying Qi and blood， and blood intake， treating various sores， and restlessness and insomnia caused by excessive blood flow. In ancient times， this formula was widely used in the treatment of surgical sores， gynecological diseases， deficiency syndrome， etc. In modern clinical practice， it is mostly used to treat gynecological， neurological， musculoskeletal， hematological diseases caused by Qi and blood deficiency. In this paper， the key information of Shengyutang was researched by reviewing relevant ancient literature， in order to provide reference for the modern application and development of this formula.

BACKGROUND:Ca2+expression in astrocytes has been found to be closely related to cognitive function,and the Ca2+signaling pathway regulated by inositol 1,4,5-trisphosphate receptors(IP3R2)and ryanodine receptor(RYR)2 receptors has become a hot spot in the study of cognitive disorder-related diseases. OBJECTIVE:To investigate the expression of Ca2+signals mediated by IP3R2 and RYR2 in hippocampal astrocytes in animal models of delayed encephalopathy after acute carbon monoxide poisoning,and to explore the possible pathogenesis of delayed encephalopathy after acute carbon monoxide poisoning. METHODS:C57BL mice with qualified cognitive function were selected by Morris water maze experiment and randomly divided into control group and experimental group.An animal model of delayed encephalopathy after acute carbon monoxide poisoning was established by static carbon monoxide inhalation in the experimental group,and the same amount of air was inhaled in the control group.Behavioral and neuronal changes,astrocyte specific marker glial fibrillary acidic protein,IP3R2,RYR2 receptor and Ca2+concentration in astrocytes of the two groups were detected using Morris water maze,hematoxylin-eosin staining,western blot,immunofluorescence double labeling and Ca2+fluorescence probe at 21 days after modeling. RESULTS AND CONCLUSION:In the Morris water maze,the escape latency of the experimental group was significantly longer than that of the control group(P<0.05).Hematoxylin-eosin staining results showed that in the experimental group,the number of hippocampal pyramidal cells decreased,the cell structure was disordered,and the nucleus was broken and dissolved.Immunofluorescence results showed that IP3R2 and RYR2 were co-expressed with glial fibrillary acidic protein in the hippocampus,and the expressions of IP3R2,RYR2 and glial fibrillary acidic protein were up-regulated in the hippocampus of the experimental group(P<0.05).Western blot analysis showed that the expressions of IP3R2,RYR2,and glial fibrillary acidic protein in the hippocampus of the experimental group were increased(P<0.05).Ca2+concentration in hippocampal astrocytes increased significantly in the experimental group(P<0.05).To conclude,astrocytes may affect Ca2+signals by mediating IP3R2 and RYR2 receptors,then impair the cognitive function of mice with carbon monoxide poisoning,and eventually lead to delayed encephalopathy after acute carbon monoxide poisoning.

Through collecting the existing clinical evidences on acupuncture and moxibustion for urticaria, the distribution of evidence in this field was mapped. A systematic search of Chinese and English literature was conducted in CNKI, Wanfang, VIP, SinoMed, PubMed, EMbase, and Cochrane Library for treatment of urticaria with acupuncture and moxibustion, published up to December 31, 2023 since inception of each database. The research status in this field was summarized using an evidence mapping approach, and methodological quality was assessed. A total of 323 randomized controlled trials (RCTs) and 22 systematic reviews were included. The number of studies on acupuncture and moxibustion for urticaria has been increasing, with a significant rise in recent years. In most RCTs, the study scale was small, and the subjects focused on chronic spontaneous urticaria in adolescents and middle-aged adults, aged 14 to 60 years. Regarding the intervention measures, the single therapy of acupuncture and moxibustion was predominant such as acupoint injection, acupoint embedding thread, and filiform needling. In acupuncture with filiform needles, the commonly used acupoints were Quchi (LI11), Xuehai (SP10), Sanyinjiao (SP6), Zusanli (ST36) and Hegu (LI4). The main outcome measures referred to effectiveness rate, score of disease severity, recurrence rate, laboratory indexes, and score of quality of life; and the short-term effect was evaluated specifically. The overall methodological quality of the included studies was relatively low. It is suggested that the future research should focus on large-scale, multi-center, high-quality clinical trials, optimize the protocols for acupuncture and moxibustion intervention, standardize the outcomes, and draw the attention to the evaluation of long-term efficacy, so as to provide clinical evidences of high certainty for urticaria treated with acupuncture and moxibustion.

Craniovertebral junction malformation is a congenital malformation located in the foramen magnum and upper cervical spine, including bone and nerve malformation, resulting in motor and sensory disorders, cerebellar and lower cranial nerves, etc. The evaluation methods of clinical symptoms and efficacy of craniovertebral junction malformation are important for the surgical indications and effects, mainly including the evaluation of clinical symptoms and the quality of life. At present, the commonly used methods in clinical work and literature are the Japanese orthopaedic association scores, visual analogue scales, 36-item short-form health survey, etc. Most of these clinical evaluations are not aimed at craniovertebral junction diseases but focus on the description of a certain type of clinical symptoms. Chicago Chiari outcome scale and syringomyelia outcome scale of Xuanwu hospital are dedicated to Craniovertebral junction malformation, but more clinical studies are needed to prove their effectiveness. Based on the literature reports, this article reviewed the previous clinical evaluation methods of craniovertebral junction malformation and discusses their applications and limitations.

Aim To investigate the effects of naringenin on atherosclerotic plaque extracellular matrix remodeling and plaque stability.Methods Murine vascular smooth muscle cells were isolated and treated with various doges of naringenin.ApoE-/-mice were fed with high-fat diet and received naringenin by lavage for 16 weeks.Intraplaque nec-rotic core,contents of collagen and fibrous cap thickness were measured by Sirius red-Haematoxylin staining.Elastin was detected by Van Gieson staining.Matrix metalloproteinase(MMP)activity was determined by gelatin zymography and fluorescence-gelatin staining.Results Naringenin(50 μmol/L)increased signal tansducer and activator of transciption 6(STAT6)phosphorylation and promoted tissue inhibitor of metalloproteinase-3(TIMP-3)expression by 3.1-fold(P＜0.001).After naringenin(80 mg/kg)treatment,compared with the control group,the area of plaque necrotic core in aor-tic root decreased by 53％(P＜0.01),the thickness of fibrous caps increased by nearly 50％(P＜0.05),and the degree of elastic fiber degradation decreased.At the same time,naringenin promoted the expression of TIMP-3 in plaques,and corre-spondingly reduced the activity of MMP in plaques.Lentivirus mediated inhibition of TIMP-3 expression in vivo could reduce the protective effect of naringenin on plaque stability.Conclusion Naringin can increase the expression of TIMP-3 in smooth muscle cells,improve the composition of extracellular matrix,and promote the stability of atherosclerotic plaque.

Aim To study the effect of maternal high-fat diet during pregnancy on endothelial to mesenchymal transition of aortic vessels in adult offspring.Methods The pregnant mice were randomly divided into normal diet group and high-fat diet group,and the offspring mice were fed normally for 16 weeks after the mother gave birth.Western blot and RT-qPCR were used to detect the expression and transcription of related proteins,and immunofluorescence and im-munohistochemical staining were used for pathological analysis.Results Compared with the offspring of maternal nor-mal diet during pregnancy,the expressions of vascular inflammatory factors,macrophage infiltration,monocyte-endothelium adhesion were significantly increased in the offspring of maternal high-fat diet(OHF)during pregnancy(P＜0.05).Vas-cular endothelial nitric oxide synthase(eNOS)activity,nitric oxide(NO)level were dramatically reduced(P＜0.05).Immunofluorescence results showed reduced endothelial cell marker CD31 and increased mesenchymal marker α-smooth muscle actin(α-SMA)in OHF.Western blot analysis further confirmed the results,which showed that maternal high fat diet reduced vascular endothelial-cadherin(VE-cadherin)and CD31 and increased α-SMA and Vimentin in the offspring(P＜0.05).The maternal high fat diet increased the extracellular matrix protein disposition and transforming growth factor beta(TGF-β)/Smad signaling in endothelium(P＜0.05).Moreover,the maternal high fat diet reduced Kruppel-like factor 2(KLF2)expression by 76％in mRNA level and 59％in protein level(P＜0.05).Conclusion Maternal high-fat diet during pregnancy lead to a transition of endothelial to mesenchyme in the offspring aorta.The results provide a clue for prevention of vascular disease in early stage.

Objective:To analyze the risk factors for postoperative pathological upgrade of prostate cancer patients with single core positive biopsy,and to attempt to build a mathematical model for predic-ting postoperative pathological upgrade in these cancer patients with single core positive biopsy.Methods:A retrospective analysis was conducted on 1 349 patients diagnosed with prostate cancer and undergoing radical prostatectomy at Peking University First Hospital from January 2015 to August 2020.The pa-tients'age,body mass index,clinical stage,prostate imaging reporting and data system(PI-RADS)scores,prostate volume in magnetic resonance imaging(MRI),Gleason score of biopsy,serum prostate specific antigen(PSA)before biopsy and operation,surgical method and pathological stage were inclu-ded in the analysis.The variables with P＜0.1 in univariate analysis were included to construct multi-variate Logistic regression and the nomogram was drawn.The model was evaluated using the receiver operating curve.Results:A total of 71 patients were included in this research,with 34 patients in the upgraded group and 37 patients in the non-upgraded group.There were no significant differences in the pa-tients'age(P=0.585),body mass index(P=0.165),operation method(P=0.08),prostate volume in MRI(P=0.067),clinical stage(P=0.678),PI-RADS score(P=0.203),difference of PSA density(P=0.063),Gleason score in biopsy(P=0.068),PSA before puncture(P=0.359)and operation(P=0.739)between the two groups.However,there were significant differences in the proportion of tumor tissue(P=0.007),postoperative pathological stage(P＜0.001)and postoperative Gleason score(P＜0.001)between the two groups.The preoperative variables with a P value of less than 0.1(prostate volume in MRI,difference of PSA density,proportion of tumor tissue and Gleason score in biopsy)in univariate analysis were included in the Logistic regression,and the nomogram was drawn.Only the prostate volume in MRI had a P value of less than 0.05.The area under the curve of the model was 0.773.Conclusion:In patients with sin-gle core positive biopsy,if the prostate volume is small or the proportion of tumor in positive core is small,clinicians should be alert to the possibility of postoperative pathology upgrading,preoperative risk stratifica-tion should be carefully considered for patients with possible pathological upgrading.This model can be used to predict the pathological upgrade of patients with single core positive biopsy.

Background/Aims: Roxadustat, an oral medication for treating renal anemia, is a hypoxia-inducible factor prolyl hydroxylase inhibitor used for regulating iron metabolism and promoting erythropoiesis. To investigate the efficacy and safety of roxadustat in patients undergoing peritoneal dialysis (PD) with erythropoietin hyporesponsiveness. Methods: Single-center, retrospective study, 81 PD patients (with erythropoietin hyporesponsiveness) were divided into the roxadustat group (n = 61) and erythropoiesis-stimulating agents (ESAs) group (n = 20). Hemoglobin (Hb), total cholesterol, intact parathyroid hormone (iPTH), brain natriuretic peptide (BNP), related indicators of cardiac function and high-sensitivity C-reactive protein (hs-CRP) were collected. Additionally, adverse events were also recorded. The follow-up period was 16 weeks. Results: The two groups exhibited similar baseline demographic and clinical characteristics. At baseline, the roxadustat group had a mean Hb level of 89.8 ± 18.9 g/L, while the ESAs group had a mean Hb level of 95.2 ± 16.0 g/L. By week 16, the Hb levels had increased to 118 ± 19.8 g/L (p < 0.05) in the roxadustat group and 101 ± 19.3 g/L (p > 0.05) in the ESAs group. The efficacy of roxadustat in improving anemia was not influenced by baseline levels of hs-CRP and iPTH. Cholesterol was decreased in the roxadustat group without statin use. An increase in left ventricular ejection fraction and stabilization of BNP were observed in the roxadustat group. Conclusions For PD patients with erythropoietin hyporesponsiveness, roxadustat can significantly improve renal anemia. The efficacy of roxadustat in improving renal anemia was not affected by baseline levels of hs-CRP0 and iPTH.

【Objective】 To investigate the risk factors of frailty syndrome in elderly patients with acute coronary syndrome （ACS） and their impact on prognosis. 【Methods】 The elderly patients with ACS aged 65 and over， who were hospitalized in the Department of Cardiology and Geriatric Cardiology of The First Affiliated Hospital of Xi’an Jiaotong University from September 2020 to February 2021， were selected in the cross-sectional survey. The patients were divided into frailty syndrome and non-frailty syndrome groups via the Chinese revised version of Tilburg Frailty Scale. We collected the patients’ activities of daily living， nutrition， depression， sleep quality， total cholesterol， triglycerides， low-density lipoprotein， and adverse events during hospitalization and within 30 days of discharge. We then performed LOG-BINOMIAL regression to analyze the risk factors of frailty syndrome. 【Results】 A total of 250 elderly ACS patients were enrolled， and 118 patients were diagnosed with frailty syndrome with 47.2% prevalence of frailty syndrome. There was a significant difference in the average score between the frailty syndrome group and the non-frailty syndrome group （11.06±2.53 vs. 5.77±1.54， P<0.01）. Multivariate regression analysis revealed that age （PR=2.01 CI： 1.81-2.22， P<0.001）， hypertension （PR=1.20 CI： 1.09-1.30， P<0.001）， chronic kidney disease （PR=1.16 CI：1.04-1.29， P=0.012）， and NT-proBNP （PR=1.20 CI： 1.07-1.35， P=0.004） were risk factors for frailty syndrome in elderly ACS patients. The incidence of arrhythmia and pulmonary infection during hospitalization and the rate of readmission within 30 days after discharge were significantly higher in the frailty syndrome group than those in the non-frailty syndrome group （P<0.05）. 【Conclusion】 There is a higher incidence of frailty syndrome in elderly patients with ACS. Older age， hypertension， chronic kidney disease and high NT-proBNP can increase the risk of frailty syndrome. In clinical practice， attention should be paid to the above factors， and reasonable intervention should be provided in time.
