Objective： To systematically evaluate the clinical efficacy and safety of Tonifying kidney and activating blood therapy for the treatment of diabetic mellitus erectile dysfunction. Methods： China National Knowledge Infrastructure(CNKI), Wanfang Data, VIP, Chinese Biomedical Database(CBM), PubMed, Cochrane Library, Embase and Web of Science were searched from inception until October 20th of 2024，for randomized controlled trials of Tonifying kidney and activating blood therapy for the treatment of diabetic erectile dysfunction. Literature screening, quality evaluation, and data extraction were carried out in accordance with relevant standards. The software of RevMan5.4 was used for the analysis of publication bias. And meta-analysis was conducted to assess the impact of this therapy on IIEF-5, total effective rate, adverse reactions. The evidence levels according to the analysis results were evaluated. Results: Totally 19 RCTs were included, involving 1 612 patients. The result of meta-analysis indicated that Tonifying kidney and activating blood therapy had advantages on the improvement of IIEF-5 scores (MD=3.59，95%CI［2.14，5.03］，P<0.01)，total effective rate (OR=4.30，95%CI［3.29，5.32］，P<0.000 01）. However, there was no statistically significant difference in the incidence of adverse reactions(OR=0.98，95%CI［0.48，2.01］，P=0.96) between the two groups. Conclusions： Tonifying kidney and activating blood therapy can improve the clinical efficacy and IIEF-5 score for the patients with diabetic erectile dysfunction. But considering the limited quantity of included studies, more high-quality studies still be needed to validate the therapeutic effect.

OBJECTIVE: To evaluate the efficacy and safety of Shexiang Tongxin Dropping Pill (STDP) in treating stable angina patients with phlegm-heat and blood-stasis syndrome by exercise duration and metabolic equivalents. METHODS: This multicenter, randomized, double-blind, placebo-controlled clinical trial enrolled stable angina patients with phlegm-heat and blood-stasis syndrome from 22 hospitals. They were randomized 1:1 to STDP (35 mg/pill, 6 pills per day) or placebo for 56 days. The primary outcome was the exercise duration and metabolic equivalents (METs) assessed by the standard Bruce exercise treadmill test after 56 days of treatment. The secondary outcomes included the total angina symptom score, Chinese medicine (CM) symptom scores, Seattle Angina Questionnaire (SAQ) scores, changes in ST-T on electrocardiogram and adverse events (AEs). RESULTS: This trial enrolled 309 patients, including 155 and 154 in the STDP and placebo groups, respectively. STDP significantly prolonged exercise duration with an increase of 51.0 s, compared to a decrease of 12.0 s with placebo (change rate: -11.1% vs. 3.2%, P<0.01). The increase in METs was significantly greater in the STDP group than in the placebo group (change: -0.4 vs. 0.0, change rate: -5.0% vs. 0.0%, P<0.01). The improvement of total angina symptom scores (25.0% vs. 0.0%), CM symptom scores (38.7% vs. 11.8%), reduction of nitroglycerin consumption (100.0% vs. 11.3%), and all domains of SAQ, were significantly greater with STDP than placebo (all P<0.01). The changes in Q-T intervals at 28 and 56 days from baseline were similar between the two groups (both P>0.05). Twenty-five participants (16.3%) with STDP and 16 (10.5%) with placebo experienced AEs (P=0.131), with no serious AEs observed. CONCLUSION STDP could improve exercise tolerance in patients with stable angina and phlegm-heat and blood stasis syndrome, with a favorable safety profile. (Registration No. ChiCTR-IPR-15006020).

Objective:To investigate the value of serum ferritin,folic acid and vitamin B12 in the treatment of multiple myeloma(MM)with bortezomib combined with chemotherapy.Methods:Clinical data of 40 MM patients admitted to our hospital from January 2020 to August 2022 and 40 hematology outpatients during the same period were reviewed.All MM patients were treated with bortezomib combined with chemotherapy.The diagnostic efficacy of serum ferritin,folic acid and vitamin B12 on MM was analyzed by ROC curve.The changes of serum ferritin,folic acid and vitamin B12 in MM patients before and after treatment were compared.According to the mean values of serum ferritin,folic acid and vitamin B12,patients were divided into high and low expression groups,and the survival of patients between the groups was compared.Results:Before treatment,the levels of serum ferritin and vitamin B12 in MM patients were significantly higher than those in control group,while folic acid was lower(all P＜0.001).The area under the curve(AUC)of MM patients diagnosed with ferritin,folic acid and vitamin B12 were 0.928,0.843 and 0.867,the specificity was 100％,67.50％and 72.50％,and the sensitivity was 80.00％,95.00％and 87.50％,respectively.After 4 cycles of chemotherapy,there were 9 cases of complete remission(CR),19 cases of very good partial remission(VGPR),6 cases of PR,4 cases of stable disease(SD)and 2 cases of progression disease(PD)in 40 MM patients.In CR group,ferritin and vitamin B12 decreased but folic acid increased after treatment compared with before treatment(all P＜0.05).The overall survival(OS)rates of patients in low expression group of ferritin and vitamin B12 were significantly higher than those in high expression group(both P＜0.01).The OS rate of patients in high expression group of folic acid was significantly higher than that in low expression group(P＜0.01).Cox regression analysis showed that ferritin was an independent prognostic factor for MM patients(HR=8.850,95％CI:2.267-34.553,P=0.002).Conclusion:Serum ferritin,folic acid and vitamin B12 have some auxiliary value in the diagnosis and efficacy evaluation of MM,and ferritin is an independent prognostic factor for MM.

Objective To investigate the mechanism of melezitose(MELE)on ulcerative colitis(UC)by structing a mouse model of ulcerative colitis(UC)induced by dextran sodium sulfate(DSS).Methods Forty-eight SPF grade male c57BL/6 mice were randomly divided into normal group(0.9％NaCl),model group(0.9％NaCl),control group(100 mg·kg-1 mesalazine)and experimental-L,-M,-H groups(20,40,80 mg·kg-1 melezitose solution).The UC model was induced by giving 3％DSS solution instead of drinking water,and the disease activity index(DAI)was evaluated.Serum levels of interleukin-1 β(IL-113),IL-6,IL-10 and tumor necrosis factor α(TNF-α)were detected by enzyme linked immunosorbent assay.The expression levels of major histocompatibility complex Ⅱ(MHC Ⅱ)and cluster of differentiation 4 receptors(CD4)protein were detected by Western blot.Results The levels of IL-1 β in serum in the experimental-M,-H groups,model group and normal group were(82.15±13.66),(75.56±11.07),(118.20±19.31)and(23.47±4.72)pg·mL-1;serum IL-6 levels were(71.54±16.48),(58.57±15.62),(140.60±5.76)and(30.33±4.15)pg·mL-1;serum IL-10 levels were(48.64±5.60),(52.65±7.99),(27.10±4.91)and(61.90±10.44)pg·mL-1;serum TNF-α levels were(70.33±8.51),(66.55±8.12),(90.88±4.90)and(34.18±4.15)pg·mL-1;the relative expression levels of MHC Ⅱ protein were 0.34±0.04,0.15±0.06,0.08±0.05 and 0.53±0.59;the relative expression levels of CD4 protein were 0.79±0.08,0.92±0.12,0.99±0.11 and 0.54±0.14,respectively.Compared with the model group,the above indexes in the experimental-M,-H groups showed statistically significant differences(P＜0.05,P＜0.01).Conclusion Melezitose could effectively improve the symptoms of UC mice;the mechanism may be through down-regulating MHC Ⅱ protein and up-regulating CD4 protein to activate T cell signal pathway to play an anti-inflammatory effect.

A 31P-quantitative nuclear magnetic resonance(qNMR)method was established for simultaneous determination of sodium α-glycerophosphate,sodium β-glycerophosphate and phosphoric acid in concentrated divitamins and sodium phosphate syrup.The qNMR experimental conditions were optimized,including hexamethylphosphoramide as internal standard,20%deuterium oxide solution as solvent,zgig pulse sequence,delay time of 30 s,and scan number of 64.The 31P-NMR peaks atδ29.80 of hexamethylphosphoramide,δ0.69 of sodiumα-glycerophosphate,δ0.17 of sodiumβ-glycerophosphate andδ0.03 of phosphoric acid were chosen as the quantitative peaks(pH of the test solution was around 4.8).Method validation was performed in terms of precision(Relative standard deviation less than 0.6%),linearity(Correlative coefficient greater than 0.999),limit of detection(23.58 μg/mL for sodium glycerophosphate and 11.61 μg/mL for phosphoric acid)and limit of quantitation(78.60 μg/mL for sodium glycerophosphate and 38.70 μg/mL for phosphoric acid).The recoveries were 99.8%?103.2%,and relative standard deviations were 0.41%?1.98%.The results showed that the reliability of 31P-qNMR method were suitable for its intended use.Seven batches of concentrated divitamins and sodium phosphate syrups were tested by the established method,of which the total phosphorus content was consistent with that of colorimetry method,but the content of sodium glycerophosphate(Sum ofαtype andβtype)was relatively low,about 82%of the labeled amount.The content of phosphoric acid was high.This method simplified sample pretreatment and had high specificity,and was more suitable for determination and quality control of concentrated divitamins and sodium phosphate syrup.

Objective To analyze the risk factors and survival status of Epstein-Barr virus(EBV)infection in pa-tients with aplastic anemia(AA)after haploid allogeneic hematopoietic stem cell transplantation(Haplo-HSCT).Methods Clinical data of 78 AA patients who underwent Haplo-HSCT in the hematology department of a hospital from January 1,2019 to October 31,2022 were analyzed retrospectively.The occurrence and onset time of EBV viremia,EBV-related diseases(EBV diseases),and post-transplant lymphoproliferative disorders(PTLD)were ob-served,risk factors and survival status were analyzed.Results Among the 78 patients,38 were males and 40 were females,with a median age of 33(9-56)years old;53 patients experienced EBV reactivation,with a total inci-dence of 67.9％,and the median time for EBV reactivation was 33(13,416)days after transplantation.Among pa-tients with EBV reactivation,49 cases(62.8％)were simple EBV viremia,2 cases(2.6％)were possible EBV di-seases,and 2 cases(2.6％)were already confirmed EBV diseases(PTLD).Univariate analysis showed that age 1＜40 years old at the time of transplantation,umbilical cord blood infusion,occurrence of acute graft-versus-host disease(aGVHD)after transplantation,and concurrent cytomegalovirus(CMV)infection were independent risk fac-tors for EBV reactivation in AA patients after Haplo-HSCT.Multivariate analysis showed that concurrent CMV in-fection was an independent risk factor for EBV reactivation in A A patients after Haplo-HSCT(P=0.048).Ritu-ximab intervention before stem cell reinfusion was a factor affecting the duration of EBV reactivation(P＜0.05).The mortality of EBV viremia,EBV diseases,and PTLD alone were 8.2％,50.0％,and 100％,respectively.The 2-year overall survival rate of patients with and without EBV reactivation were 85.3％,and 90.7％,respectively,difference was not statistically significant(P=0.897).However,patients treated with rituximab had 2-year lower survival rate than those who did not use it,with a statistically significant difference(P=0.046).Conclusion EBV reactivation is one of the serious complications in AA patients after Haplo-HSCT,which affects the prognosis and survival of patients.

OBJECTIVE: To explore the anti-inflammatory effects of ethyl lithospermate in lipopolysaccharide (LPS)-stimulated RAW 264.7 murine-derived macrophages and zebrafish, and its underlying mechanisms. METHODS: 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyltetrazoliumbromide (MTT) assays were performed to investigate the toxicity of ethyl lithospermate at different concentrations (12.5-100 µ mol/L) in RAW 264.7 cells. The cells were stimulated with LPS (100 ng/mL) for 12 h to establish an inflammation model in vitro, the production of pro-inflammatory cytokines interleukin (IL)-6 and tumor necrosis factor α (TNF-α) were assessed by enzyme linked immunosorbent assay (ELISA). Western blot was used to ascertain the protein expressions of signal transducer and activator of transcription 3 (STAT3), nuclear factor kappa B (NF-κB) p65, phospho-STAT3 (p-STAT3, Tyr705), inhibitor of NF-κB (IκB) α, and phospho-I κB α (p-IκB α, Ser32), and confocal imaging was used to identify the nuclear translocation of NF-κB p65 and p-STAT3 (Tyr705). Additionally, the yolk sacs of zebrafish (3 days post fertilization) were injected with 2 nL LPS (0.5 mg/mL) to induce an inflammation model in vivo. Survival analysis, hematoxylin-eosin (HE) staining, observation of neutrophil migration, and quantitative real-time polymerase chain reaction (qRT-PCR) were used to further study the anti-inflammatory effects of ethyl lithospermate and its probable mechanisms in vivo. RESULTS: The non-toxic concentrations of ethyl lithospermate have been found to range from 12.5 to 100 µ mol/L. Ethyl lithospermate inhibited the release of IL-6 and TNF-α(P<0.05 or P<0.01), decreased IκBα degradation and phosphorylation (P<0.05) as well as the nuclear translocation of NF-κB p65 and p-STAT3 (Tyr705) in LPS-induced RAW 264.7 cells (P<0.01). Ethyl lithospermate also decreased inflammatory cells infiltration and neutrophil migration while increasing the survival rate of LPS-stimulated zebrafish (P<0.05 or P<0.01). In addition, ethyl lithospermate also inhibited the mRNA expression levels of of IL-6, TNF-α, IκBα, STAT3, and NF-κB in LPS-stimulated zebrafish (P<0.01). CONCLUSION Ethyl lithospermate exerts anti-Inflammatory effected by inhibiting the NF-κB and STAT3 signal pathways in RAW 264.7 macrophages and zebrafish.

Objective To investigate the occurrence and clinical characteristics of the adverse reactions of hyperammonemic encephalopathy caused by sodium valproate and provide reference for the safe clinical use of the drug.Methods CNKI,WanFang Data,VIP,PubMed and Web of Science databases were electronically searched to collect case reports on valproate-induced hyperammonemic encephalopathy from the inception to March 2023.The extracted data was conducted for statistical analysis.Results A total of 37 documents with 41 patients were finally included.Among them,28 patients(68.3%)were males and 13 patients(31.7%)were females,aged 5 to 78 years,the median age was 41 years;most of the patients had no underlying diseases but the blood ammonia concentrations of them were abnormally high in laboratory tests,and the main clinical manifestations were neurological impairment such as cognitive impairment,drowsiness,coma and other disorders of consciousness.After drug discontinuation,drug switch and symptomatic treatment,they gradually recovered consciousness and the blood ammonia concentrations returned to normal.Conclusion It is not easy to recognize and detect the high blood ammonia encephalopathy caused by the application of sodium valproate in clinical practice,so the clinical performance and blood concentration of this drug should be closely monitored,and once the abnormalities are detected,patients should be treated symptomatically in time to ensure the safety of the drug use.

OBJECTIVE: This study was aimed at investigating the carrier rate of, and molecular variation in, α- and β-globin gene mutations in Hunan Province. METHODS: We recruited 25,946 individuals attending premarital screening from 42 districts and counties in all 14 cities of Hunan Province. Hematological screening was performed, and molecular parameters were assessed. RESULTS: The overall carrier rate of thalassemia was 7.1%, including 4.83% for α-thalassemia, 2.15% for β-thalassemia, and 0.12% for both α- and β-thalassemia. The highest carrier rate of thalassemia was in Yongzhou (14.57%). The most abundant genotype of α-thalassemia and β-thalassemia was -α ^3.7/αα (50.23%) and β ^IVS-II-654/β ^N (28.23%), respectively. Four α-globin mutations [CD108 (ACC>AAC), CAP +29 (G>C), Hb Agrinio and Hb Cervantes] and six β-globin mutations [CAP +8 (C>T), IVS-II-848 (C>T), -56 (G>C), beta nt-77 (G>C), codon 20/21 (-TGGA) and Hb Knossos] had not previously been identified in China. Furthermore, this study provides the first report of the carrier rates of abnormal hemoglobin variants and α-globin triplication in Hunan Province, which were 0.49% and 1.99%, respectively. CONCLUSION Our study demonstrates the high complexity and diversity of thalassemia gene mutations in the Hunan population. The results should facilitate genetic counselling and the prevention of severe thalassemia in this region.
