ObjectiveMicrotube associated protein-2 （MAP-2）， alpha-tubulin （α-tubulin）， and synaptophysin （SYP） are important proteins in neuronal signal communication. This paper observed the effects of modified Zhigancao Tang on the expression of serum α-Synuclein （α-Syn） and its oligomers， MAP-2， α-tubulin， and SYP of patients with liver and kidney deficiency of Parkinson's disease （PD）， analyzed their correlation， and evaluated the therapeutic effect of modified Zhigancao Tang in patients with liver and kidney deficiency of PD based on α-Syn transmission pathway mediated by neuronal communication in vivo. MethodsA total of 60 patients with PD who met the inclusion criteria were randomly divided into a treatment group （30 cases） and a control group （30 cases）. Both groups were treated on the basis of PD medicine， and the treatment group was treated with modified Zhigancao Tang. Both groups were treated for 12 weeks. The changes in UPDRS score， TCM syndrome score， and expression of serum α-Syn and its oligomers， MAP-2， α-tubulin， and SYP were observed before and after 12 weeks of treatment in each group. The correlation between the above-mentioned serum biological indexes and the levels of serum α-Syn and its oligomers was analyzed. ResultsAfter treatment， the TCM syndrome score， UPDRS score， UPDRS-Ⅱ score， and UPDRS-Ⅲ score of the treatment group were significantly decreased （P<0.05， P<0.01）. The UPDRS score， UPDRS-Ⅱ score， and UPDRS-Ⅲ scores in the treatment group were significantly decreased compared with those in the control group after treatment （P<0.05）. After treatment， the total effective rate of the control group was 63.3% （19/30）， and that of the treatment group was 86.7% （26/30）. The clinical effect of the observation group was better than the control group （Z=-2.03， P<0.05）. The total effective rate of the observation group was better than that of the control group， and the difference was statistically significant （χ²=5.136， P<0.05）. After treatment， the oligomer level of serum α-Syn and MAP-2 level in the treatment group were significantly decreased （P<0.05， P<0.01）. The levels of serum α-Syn and its oligomers， as well as α-tubulin in the treatment group， were significantly decreased compared with those in the control group after treatment （P<0.05， P<0.01）. Serum α-Syn was correlated with serum MAP-2 and α-Syn oligomer in patients with PD （P<0.05， P<0.01） but not correlated with serum SYP . Serum α-Syn oligomers of patients with PD were correlated with serum MAP-2 and α-tubulin （P<0.05， P<0.01） but not correlated with serum SYP level. Serum SYP of patients with PD was correlated with serum MAP-2 （P<0.05）. ConclusionModified Zhigancao Tang has a therapeutic effect on patients with liver and kidney deficiency of PD by inhibiting the production of α-Syn oligomers and intervening α-Syn microtubule transport pathway in vivo.

Objective:To retrospectively analyze the treatment status of tyrosine kinase inhibitors (TKI) in newly diagnosed patients with chronic myeloid leukemia (CML) in China.Methods:Data of chronic phase (CP) and accelerated phase (AP) CML patients diagnosed from January 2006 to December 2022 from 77 centers, ≥18 years old, and receiving initial imatinib, nilotinib, dasatinib or flumatinib-therapy within 6 months after diagnosis in China with complete data were retrospectively interrogated. The choice of initial TKI, current TKI medications, treatment switch and reasons, treatment responses and outcomes as well as the variables associated with them were analyzed.Results:6 893 patients in CP ( n=6 453, 93.6%) or AP ( n=440, 6.4%) receiving initial imatinib ( n=4 906, 71.2%), nilotinib ( n=1 157, 16.8%), dasatinib ( n=298, 4.3%) or flumatinib ( n=532, 7.2%) -therapy. With the median follow-up of 43 ( IQR 22-75) months, 1 581 (22.9%) patients switched TKI due to resistance ( n=1 055, 15.3%), intolerance ( n=248, 3.6%), pursuit of better efficacy ( n=168, 2.4%), economic or other reasons ( n=110, 1.6%). The frequency of switching TKI in AP patients was significantly-higher than that in CP patients (44.1% vs 21.5%, P<0.001), and more AP patients switched TKI due to resistance than CP patients (75.3% vs 66.1%, P=0.011). Multi-variable analyses showed that male, lower HGB concentration and ELTS intermediate/high-risk cohort were associated with lower cytogenetic and molecular responses rate and poor outcomes in CP patients; higher WBC count and initial the second-generation TKI treatment, the higher response rates; Ph + ACA at diagnosis, poor PFS. However, Sokal intermediate/high-risk cohort was only significantly-associated with lower CCyR and MMR rates and the poor PFS. Lower HGB concentration and larger spleen size were significantly-associated with the lower cytogenetic and molecular response rates in AP patients; initial the second-generation TKI treatment, the higher treatment response rates; lower PLT count, higher blasts and Ph + ACA, poorer TFS; Ph + ACA, poorer OS. Conclusion:At present, the vast majority of newly-diagnosed CML-CP or AP patients could benefit from TKI treatment in the long term with the good treatment responses and survival outcomes.

Background: Red blood cell distribution width/platelet count ratio (RPR) is a reliable prognostic assessment indicator for numerous diseases. However, no studies to date have examined the relationship between RPR and the prognosis of diffuse large B-cell lymphoma (DLBCL).Therefore, this study aimed to investigate the correlation between RPR and the clinical characteristics and prognosis of patients with diffuse large B-cell lymphoma. Methods: We retrospectively studied 143 patients with newly diagnosed DLBCL and used the median value as the RPR threshold. We also investigated the correlation of pretreatment RPR level with clinical characteristics and its impact on DLBCL prognosis. Results: Using the median value as the cut-off, patients with DLBCL were divided into a low RPR group (＜0.0549) and a high RPR group (≥0.0549). Patients in the high RPR group were older, had a later Ann Arbor stage, were prone to bone marrow invasion, and had a higher National Comprehensive Cancer Network International Prognostic Index score (P ＜ 0.05). A survival analysis showed that progression-free survival (PFS) (P =0.003) and overall survival (OS) (P ＜0.0001) were significantly shorter in the high versus low RPR group. A multifactorial Cox analysis showed that bone marrow invasion and elevated lactate dehydrogenase (LDH) were separate risk factors for PFS (P ＜0.05), while an RPR ≥0.0549 and elevated LDH were separate risk factors for OS (P ＜0.05). Conclusion A high RPR (≥0.0549) in patients with newly diagnosed DLBCL is an independent risk factor for a poor prognosis.

The clinical features and genetic variants of the patient with sitosterolemia who was referred to Shanghai Children′s Medical Center, Shanghai Jiaotong University School of Medicine from June 2019 to January 2020 were retrospectively analyzed.The patient was treated with Ezetimibe tablets combined with diet control, and the follow-up was performed regularly.Besides, a relevant literature review was conducted.A 7-year and 5-month-old boy was referred to the hospital for " repeated thrombocytopenia for 7 months" with normal serum cholesterol.The whole exome sequencing showed that compound heterozygous mutations (p.Arg446*, p.Gln251*) in ABCG5 gene were inherited from their parents respectively.Hence, he was diagnosed with sitosterolemia.After 29 days of treatment with Ezetimibe tablets combined with diet control, the patient′s platelets returned to normal values without obvious adverse reactions related to drugs.Children with sitosterolemia may present with rare thrombocytopenia, and the therapeutic effects of Ezetimibe tablets combined with diet control are favorable.

  Objective  To study the demographic and clinical characteristics, correlation of genotype and phenotype and treatment of Blau syndrome to facilitate early diagnosis and timely treatment of Blau syndrome.  Methods  Seventy-two patients with Blau syndrome from 11 centers from May 2006 to April 2022 were retrospectively analyzed, and their general information, clinical data, laboratory examination and treatment medication were collected.  Results  The distribution of patients with Blau syndrome was uniform in geographical north and south of China, and there was no obvious gender bias. The mean age of onset was (14.30±12.81) months, and the age of diagnosis was (55.18±36.22) months. 35% of patients with Blau syndrome happened before 1 year old, and all patients developed before 5 years old. 87.50% (63/72) had granulomatous arthritis, 65.28% (47/72) had rash, 36.11% (26/72) had ocular involvement, 27.78% (20/72) had fever, and 15.28% (11/72) had pulmonary involvement. Arthritic manifestations of Blau syndrome were most at risk, followed by rash, ocular involvement, and fever.The first 25 months of the disease, the risk of developing a rash was the greatest. The risk of developing arthritis was the greatest between 25 months and 84 months. The main mutations were p.R334Q and p.R334W, and patients with p.R334Q mutation had relatively high incidence of fever (35.71%[5/14] vs. 14.29%[1/7], P=0.43) and ocular involvement (42.86%[6/14]vs. 28.57%[2/7], P=0.51). There was a relatively high incidence of rash (85.71%[6/7] vs. 64.29%[9/14], P=0.59) in patients with the p.R334W mutation. Forty-five patients(62.50%)were treated with a combina-tion of glucocorticoid and methotrexate. Twenty-two patients were treated with tumor necrosis factor antagonist in addition to glucocorticoid and methotrexate.  Conclusions  The risk of different clinical manifestations of Blau syndrome from high to low was arthritis, followed by rash, ocular involvement and fever. The main treatment was glucocorticoid combined with methotrexate, to which biological agents could be added.

To compare the effects of endogenous 3-nitrotyrosine and non-natural 4-nitrophenylalanine in PD-L1 vaccine on the differentiation of T cell subsets, two immunogenic amino acids were introduced into the same site of PD-L1 vaccine. Two PD-L1 mutants with 3-nitrotyrosine and 4-nitrophenylalanine were obtained, respectively, using genetic code expansion technology. Mice were immunized with these two mutants, and their effects on the differentiation of T cell subsets in spleen were analyzed. The results of flow cytometry showed that the introduction of 4-nitrophenylalanine in PD-L1 vaccine could promote the polarization of Th1 cells while reducing the proportion of Treg cells; the introduction of 3-nitrotyrosine had no effect on the polarization of Th1 cells, while significantly increasing the proportion of Treg and Th17 cells. The introduction of both into PD-L1 vaccine could promote the response of CD8+ T cells in spleen, and the response of PD-L1 mutant containing 4-nitrophenylalanine was stronger. In summary, the non-natural 4-nitrophenylalanine is more suitable for the design of tumor vaccines as compared with endogenous 3-nitrotyrosine.

Objective To study the intervention effect of systematic nutrition combined with rhythmic exercise on patients with abnormal liver metabolism. Methods According to the theory of system nutrition and health rhythm kinematics, selected 56 subjects with abnormal liver metabolism were selected, and the combined intervention of system nutrition and rhythm movement was conducted regularly every day for 3 consecutive months using the techniques such as liver transient elastography (FibroScan) and bioelectric whole body health scanning system (DDFAO). Results Compared with the pre-intervention period, the liver fat attenuation, liver hardness and liver functional activity of the subjects were significantly improved after intervention. Conclusion The systematic nutrition combined with rhythmic exercise significantly reduced the risk of abnormal liver metabolism in subjects, which may play an important role in preventing liver diseases and promoting the recovery of liver function.

Objective To compare the blood lipid levels of different brachial-ankle pulse wave velocity (baPWV) in young and middle-aged people with normal blood pressure and to explore the related factors affecting baPWV.Methods From January 2014 to December 2017,the clinical data of one thousand two hundred and sixty-eight middle-aged and young people with normal blood pressure who underwent physical examination in Dongying People's Hospital were retrospectively analyzed.Using baPWV＜ 1 400 cm/s as the standard of normal arterial stiffness,the patients were divided into normal arterial stiffness group (normal group,1 128 cases),abnormal arterial stiffness group (abnormal group,baPWV ≥ 1 400 cm/s,140 cases).The blood lipid indexes of the two groups were analyzed and compared.Logistic regression analysis was used for multivariate analysis and linear correlation analysis was used for linear correlation analysis.Pearson correlation analysis was used.Results Compared with the normal group,TC ((4.99 ± 1.10) mmol/L vs.(4.48 ± 1.03) mmoL/L,t =5.830),TG ((1.62 ± 0.27) mmol/L vs.(1.49 ± 0.23) mmol/L,t=5.102),LDL-C[(3.25±0.23) mmol/L vs.(3.11±0.16) mmol/L,t =4.712),Apo B((0.96 ±0.07) g/L vs.(0.87±0.08) g/L,t =4.297)in abnormal group all increased,and HDL-C((1.15±0.09) mmol/L vs.(1.27±0.07) mmol/L,t =4.712) decreased,and the differences were statistically significant (P＜0.05).Smoking,high FPG,high LDL-C,high Apo B,low HDL-C were the independent factors affecting baPWV abnormality (P＜ 0.05).TC,TG,LDL-C,Apo B and baPWV in abnormal group were positively correlated(P＜0.05),and HDL-C and baPWV were negatively correlated(P＜0.05).There was a linear regression relationship between LDL-C,Apo B and baPWV (P＜0.05).Conclusion The increase of LDL-C and Apo B are closely related to early arterial disease in the low-risk populations of normotensive young and middle-aged people,even the risk of blood lipid may already exist within the normal range.

Objective To improve the diagnosis of oligodendroglioma(OD)in cerebellar hemispheres and discuss MRI features. Methods Clinical and imaging data of 7 cases with OD in cerebellar hemispheres were analyzed retrospectively,which were confirmed by surgery and pathology.Results In 7 patients,4 patients were OD,and 3 patients were anaplastic oligodendroglioma(AOD).MRI showed hypointense on T1WI and vividly hyperintense or mixed hyperintense on T2WI.The time intensity curve(TIC)manifested rise slowly;DWI(b=1 000 s/mm2) showed homogeneously hypointense or iso-hypointense.The ratios of OD and AOD were 1.753±0.784,1.660±0.551 respectively;Magnetic resonance spectroscopy(MRS)of oligodendrogliomas revealed a increased choline(Cho)and reduced N-acetylaspartate(NAA)without lactate(Lac)peak.Conclusion MRI manifestation of OD in cerebellar hemispheres has certain characteristics:the boundary of lesion is unclear, irregular in shape,easy to cystic and necrotic,with or without peripheral edema of the tumor,delayed enhancement,higher in Cho peak,lower in NAA peak and lacking in Lac peak.

It is well established that cardiovascular diseases are the leading causes of diabetes-related death. Endothelial dysfunction is widely accepted as the initial and critical factor contributing to diabetic vascular diseases. Insulin resistance may result in vascular endothelial dysfunction, which in turn aggravates diabetic vascular diseases. Via PI3K/Akt signaling pathway, insulin inhibits the function of FoxOs, which, endothelial FoxO1 especially, exerts an important role in atherosclerosis and angiogenesis. In this regard, Wang et al. characterized 10 FoxO1 target genes regulated by insulin in endothelial cells, among which, CITED2, a transcriptional coregulator, was selected to extensively investigate its role and the underlying mechanism of insulin-regulated angiogenesis. CITED2 was significantly increased in vascular endothelial cells in diet-induced mice, ob/ob mice, as well as obese type 2 diabetic patients, all of those models or subjects are accompanied by insulin resistance. In endothelial cells, insulin significantly down-regulated CITED2 expression through insulin receptor-PI3K-Akt-FoxO1 pathway. Inhibition of CITED2 resulted in significant increases in proliferation and tube formation of endothelial cells. Overexpression of CITED2, however, repressed the transactivation of HIF. The study on the mouse model with hind limb ischemia showed that endothelial CITED2 deficiency gave rise to significant increases of expression of endothelin-1, a well-known HIF target gene, induced by ischemia or hypoxia, suggesting that CITED2 inhibited endothelial angiogenesis via suppressing HIF transactivation. In summary, insulin resistance accompanying obesity and type 2 diabetes leads to enhanced CITED2 expression, consequently impairing HIF signaling and proangiogenic capacity in endothelial cells. Inhibition of CITED2 will be a promising novel way to deal with ischemic cardiovascular diseases in diabetic patients.
