Clinical Characteristics and Prognosis of Patients with Hematological Malignancies Superimposed with Solid Tumors / 中国实验血液学杂志

OBJECTIVE@#To investigate the clinical characteristics and prognosis of hematological malignancies superimposed patients with solid tumors.@*METHODS@#The clinical data of 30 patients with more than two kinds of malignancy (the second is hematological malignancy) from October 2011 to October 2020 in Department of Hematology, Jiangning Hospital Affiliated to Nanjing Medical University were collected and analyzed retrospectively. The overall survival time was used as the prognostic evaluation standard, and the survival of patients were analyzed by KaplanMeier method. Logrank test and Cox regression model were used to carry out univariate and multivariate retrospective analysis on clinical and laboratory parameters of 30 patients.@*RESULTS@#Among 30 cases, 20 were male, 10 were female, the median age of onset of the second tumor was 70 years old. The common types of the secondary hematological malignancies to solid tumors are myelodysplastic syndrome, acute myeloid leukemia, multiple myeloma. Univariate analysis showed that patients' gender, age, type of solid tumors, the onset of interval between two kinds of tumor, chromosome karyotype were not related to do with the patients' overall survival time. Type of hematologic disease, ECOG score were associated with patients' overall survival time, and the multivariate analysis showed that the type of hematologic disease and ECOG score were independent risk factors for patients with poor prognosis.@*CONCLUSION@#Patients superimposed with solid tumors complicated with myelodysplastic syndrome or acute leukemia and ECOG score ≥3 have poor prognosis and shorter overall survival time, which are independent risk factors influencing the prognosis. Bone marrow injury, immune dysfunction and genetic susceptibility after chemoradiotherapy may be the main causes of these diseases.

Influencing factors of indocyanine green fluorescence imaging quality in laparoscopic liver tumor surgery / 中华肝胆外科杂志

Indocyanine green (ICG) fluorescence imaging technology has been applied in laparoscopic surgery. It is possible to highly visualize the tumor cutting edge and liver segment boundary during laparoscopic hepatectomy. Although the application of this technique in liver tumor surgery has become more and more mature, the factors affecting the quality of fluorescence imaging are still not completely clear. In this paper, we analyzed and summarized the effects of different factors such as ICG administration scheme, imaging acquisition, tumor characteristics of patients and preoperative liver function indexes on the quality of intraoperative ICG imaging, in order to provide new ideas and practical experience for clinical practice and research.

Analysis of Non-genetic Factors Influencing the Overall Survival of Multiple Myeloma Patients / 中国实验血液学杂志

OBJECTIVE@#To explore the non-genetic factors of overall survival in patients with multiple myeloma (MM).@*METHODS@#Kaplan-Meier survival curve, Log-rank test and Cox regression model were used to carry out univariate and multivariate retrospective analysis on clinical and laboratory parameters of 51 patients who were newly diagnosed with MM and had complete follow-up data in the Department of Hematology, the Affiliated Jiangning Hospital of Nanjing Medical University from November 2011 to October 2019.@*RESULTS@#Fifty-one patients included 29 males and 22 females. Followed up to December 2019, 21 cases died and 30 cases survived. The univariate analysis showed that the overall survival time of the patients was influenced by age, disease stage, standard treatment, new drugs, maintenance treatment, hypercalcemia, globulin, albumin, and hemoglobin. The overall survival time of patients with age <65 years old, ISS stage I and II, standardized treatment, new drugs, normal or below normal blood calcium, normal or below normal globulin, albumin ≥35 g/L or hemoglobin ≥100 g/L was prolonged significantly (P<0.05). The multivariate analysis showed that maintenance treatment, hypercalcemia (≥2.6 mmol/L), and hemoglobin (<100 g/L) were independent risk factors influencing the prognosis of MM patients.@*CONCLUSION@#Patients with blood calcium ≥2.6 mmol/L, hemoglobin <100 g/L, and who do not undergo regular maintenance therapy show a poor prognosis.

Prognostic significance of the hemoglobin A1c level in non-diabetic patients undergoing percutaneous coronary intervention: a meta-analysis / 中华医学杂志(英文版)

BACKGROUND@#The predictive value of hemoglobin A1c (HbA1c) levels in non-diabetic patients with myocardial infarction undergoing percutaneous coronary intervention (PCI) is still controversial. This study aimed to evaluate whether HbA1c levels were independently associated with adverse clinical outcomes in non-diabetic patients with coronary artery disease (CAD) who had undergone PCI by performing a meta-analysis of cohort studies.@*METHODS@#This meta-analysis included non-diabetic patients with CAD who had undergone PCI. A systematic search for publications listed in the PubMed, Embase, and Cochrane Library databases from commencement to December 2018 was conducted. Studies evaluating the adverse clinical outcomes according to abnormal HbA1c levels in non-diabetic patients diagnosed with CAD who had undergone PCI were eligible. The primary outcomes were long-term all-cause deaths and long-term major adverse cardiac events, and the secondary outcome was short-term all-cause deaths. The meta-analysis was conducted with RevMan 5.3 and Stata software 14.0. Odds ratios (ORs) were pooled using a random or fixed-effects model, depending on the heterogeneity of the included studies. Sub-group analysis or sensitivity analysis was conducted to explore potential sources of heterogeneity, when necessary.@*RESULTS@#Six prospective cohort studies involving 10,721 patients met the inclusion criteria. From the pooled analysis, abnormal HbA1c levels were associated with increased risk for long-term all-cause death (OR 1.39, 95% confidence interval [CI] 1.16-1.68, P = 0.001, I = 45%). Sub-group analysis suggested that abnormal HbA1c levels between 6.0% and 6.5% predicted higher long-term major adverse cardiac event (including all-cause deaths, non-fatal myocardial infarction, target lesion revascularization, target vessel revascularization, recurrent acute myocardial infarction, heart failure requiring hospitalization, and stent thrombosis) risk (OR 2.05, 95% CI 1.46-2.87, P < 0.001, I = 0). Contrarily, elevated HbA1c levels were not associated with increased risk of short-term all-cause death (OR 1.16, 95% CI 0.88-1.54, P = 0.300, I = 0).@*CONCLUSIONS@#An abnormal HbA1c level is an independent risk factor for long-term adverse clinical events in non-diabetic patients with CAD after PCI. Strict control of HbA1c levels may improve patient survival. Further studies in different countries and prospective cohort studies with a large sample size are required to verify the association.

Molecular mechanism of vascular remodeling in hypertension and Chinese medicine intervention / 生理学报

Vascular remodeling is a significant pathological characteristic of hypertension, which is regulated by complex regulatory networks. The vascular remodeling may be adaptive initially, however it becomes maladaptive and decompensation eventually and further compromises target organ function, leading to hypertensive cardiovascular complications. This review focuses on the role and mechanisms of vascular remodeling in the pathogenesis and progression of hypertension and its complications. Moreover, the strategies of syndrome differentiation of traditional Chinese medicine application provide clinical and theoretical evidences for hypertensive vascular remodeling therapy. A better understanding of underlying signaling pathways, therapeutic targets in vascular remodeling, as well as screening of active ingredients from traditional Chinese medicine may be able to provide some effective approaches for vascular protection in hypertensive diseases.

Decitabine combined with arsenious acid in the treatment of patients with higher-risk myelodysplastic syndromes and chronic myelomonocytic leukemia / 中国实用内科杂志

OBJECTIVE: To evaluate the clinical efficacy of decitabine combined with arsenious acid in the treatment of patients with higher-risk myelodysplastic syndromes(MDS) and chronic myelomonocytic leukemia(CMML). METHODS: Totally 39 patients with MDS and 8 patients with CMML received the treatment of decitabine and arsenious acid from April 2016 to December 2018. Decitabine [20 mg/(m~2·d)] and arsenious acid [0.15 mg/(m~2·d)] were administered intravenously for 5 consecutive days every 4-6 weeks. Patients who achieved complete or partial remission entered into the consolidation cycle. Efficacy and influencing factor were analyzed. RESULTS: Clinical response were observed in 31 patients after a median of 2 courses(ranging 1-12) of treatment. The overall response rate(ORR) was 66.0%. The median duration of response was 16 weeks(ranging 2-52 weeks). There were 8 cases(17.0%) of complete remission(CR), 10 cases(21.3%) of partial remission(PR),12 cases(25.5%) of hematological improvement(HI), 1 case(2.1%) of marrow complete remission(mCR), 8 cases(17.0%) of stable disease(SD), and 1 case(2.1%) of progressive disease(PD). By next generation sequencing, 25 genes mutated with 70 times in 33 cases. The mutation frequency of epigenetic regulators(57.6%) was higher than splicing factors(33.5%), transcription factors and kinase signaling(54.5%),and TP53(21.2%)(P<0.01). There was no significant difference in response rates among these patients(47.4%, 54.5%, 50.0% and85.7%, P=0.977). Gene mutation frequency(VAF) of patients who responded to the regimen declined significantly(16.67% vs. 10.26%,P=0.014). CONCLUSION: Decitabine combined with arsenious acid has significant effect in the treatment of patients with higher-risk MDS and CMML and is well-tolerated. Gene mutation test results by next generation sequencing might be related to clinical response.

Detection and Analysis of Candida Albicans Enolase Antigen-Specific T Cells in Heathy Individuals by ELISPOT Assay / 现代检验医学杂志

Objective To observe the T cells immune response to Enolase (Eno),an immunodominant antigen of Candida albicans.Methods Determined the frequencies of positive spot-forming cells (SFCs) of Eno antigen-specific T cells secreting IFN-γ,IL-4 and IL-17A in the PBMCs of 25 healthy individuals by ELISPOT assay.Results After Eno stimulation,the SFCs of IFN-γ,IL-4 and IL 17A in 25 healthy persons were 14.00(8.50,39.00),0(0,0) and 2(1,4.50),respectively.Either the SFCs of IFN-γ or those of IL-17A were significantly higher than those of IL-4 (P＜0.05).The difference between SFCs of IFN-γ and those of IL-17A was also significant (P=0).The response rates of IFN-γ,IL-4 and IL-17A were 100％ (25/25),4.00％ (1/25) and 88.00％ (22/25),respectively.The difference between either IFN-γor IL 17A and IL-4 was significant (values all P＜0.05).Eno induced strong response (SCFs≥20) for IFN-γ in 10 healthy individuals (40.00％,10/25),but failed to induce strong response for IL-17A and IL-4 in all the volunteers.Major healthy individuals (84.00％,21/25)showed both Th1 and Th17 cells response against Eno,12.00％ (3/25) showing Th1 cells response in isolation,and none showed Th2 or Th17 cells response individually.Conclusion Eno of Candida albicans could induce immunodominant responses of Th1 and Th17 cells,which was considered to provide protection to IC.Eno might be a potential protective vaccine against IC.

Duplex PCR for rapid detection of the drug-resistant genes KPC and NDM / 医学研究生学报

ObjectiveThe nucleic acid technology for detecting drug-resistant genes has become one of the powerful tools for monitoring and controlling the spreading of drug-resistant bacteria. This study was to establish a method for rapid detection of the drug-resistant genes KPC and NDM and provide some guidance in clinical drug use and monitoring the prevalence of drug-resistant bacteria in the hospital.MethodsAccording to the conserved regions of Klebsiella pneumoniae carbapenemase (KPC) and New Delhi metallo-β-lactamase (NDM), we designed the primers of duplex PCR, optimized the amplification system and established a method for simultaneous detection of the drug-resistant genes KPC and NDM. Then, we analyzed the sensitivity and specificity of the method and applied it to the detection of Pseudomonas aeruginosa and Klebsiella pneumoniae.ResultsThe sequences of KPC and NDM exhibited a 100% consistency with those of the original ones. Target fragments of the desired size of 151 bp were detected in the KPC-2 positive standard and Klebsiella pneumoniae ATCC BAA 1705 standard strains, and those of the desired size of 261 bp were observed in the NDM-2 positive standard strain and NDM-positive pneumococcal bacteria, neither with non-specific amplification. Sequencing of the PCR products showed a 100% consistency between the sequences of the products and those of the drug-resistant genes KPC-2 and NDM-1. The detectable limits of KPC and NDM for duplex PCR were 7×102 and 5×102 copies per reaction respectively. Drug-resistant genes were detected in 12 (92.3%) of the 13 carbapenems-resistant strains, including 10 KPC-positive (83.3%) and 2 NDM positive ones (16.7%), but neither KPC nor NDM in the other 10 carbapenems-sensitive strains. In the 13 strains of Pseudomonas aeruginosa, KPC was detected in 2 (33.3%) of the 6 carbapenems-resistant ones, but neither KPC nor NDM in the other 7.ConclusionThe duplex PCR method can be used for rapid and effective detection of the drug-resistance genes KPC and NDM, with the advantages of high sensitivity and specificity, and is therefore of great significance for guiding clinical drug use and monitoring the spreading of carbapenems-resistant bacteria in the hospital.

The survival duration and the tumors size of the mice were recorded and the Kaplan-Meier curve was made; microscopic observation of apoptosis of tumor cells in vivo was done using TUNEL staining.@*RESULTS@#After 72 h of injection, inhibition rate of tumor cell in normal saline group, As2O3 group, Rg3 group and As2O3+Rg3 group was (5.66±0.31)%, (65.58±4.75)%, (44.69±3.32)% and (82.67±5.43)%, respectively. Inhibition rate of tumor cell in As2O3 group, Rg3 group and As2O3+Rg3 group was significantly higher than that of normal saline group (P<0.01); inhibition rate of tumor cells of As2O3+Rg3 group was significantly higher than that of the two groups given As2O3 or Rg3 alone (P<0.01). The tumor volume of As2O3 group, Rg3 group and As2O3+Rg3 group shrank to (65.38±3.25)%, (77.68±3.43)% and (42.65±3.55)% of the original, tumor volume of saline group was 1.21 times of the original size (P<0.01); Median survival of saline group, Rg3 group, As2O3 group were significantly shorter than that of As2O3+Rg3 group (P<0.01); co-ordinated intervention ability of As2O3+Rg3 on NCI-H1299 cell was significantly higher than that of As2O3 or Rg3, separately.@*CONCLUSIONS@#As2O3 combined with Rg3 can significantly inhibit proliferation of NCI-H1299 cells in lung cancer, prolong survival of tumor-bearing nude mice, and promote tumor cell apoptosis, and have significant effect on lung cancer treatment.

Protection effect of Xuanfudaizhetang on reflux esophagitis in rats

OBJECTIVE@#To study protection effect of Xuanfudaizhetang on reflux esophagitis in rats.@*METHODS@#A total of 50 Wistar rats were randomly divided into groups A, B, C, D and E with 10 in each. Reflux esophagitis model in rats was established by incomplete helicobacter seam+lower esophagus sphincterotomy. All rats were divided into 5 groups: group A as control group, group B as model group, group C with saline lavage treatment, group D with motilium treatment, group E with Xuanfudaizhetang lavage treatment. Recovery of esophageal, gastric mucosa and pH changes of rats were compared between groups.@*RESULTS@#Weight gain in group D and E was significantly higher in than group C; the esophageal mucosa grades and esophagus tissue pathological morphology grades of group D and E were higher than that of group B and C with significant difference between groups (P<0.05); pH of lower esophageal mucosa in group D and E increased significantly than that in the group B and C (P<0.05), and the distal mucosal pH dropped significantly in the group B and C (P<0.05).@*CONCLUSIONS@#Xuanfudaizhetang can obviously improve the pH of lower esophageal mucosa in rats with reflux esophagitis, decrease pH value of gastric mucosal, thus improve esophageal mucosa pathological conditions to achieve therapeutic effect on reflux esophagitis.
