Effect of viral hepatitis on type 2 diabetes: A Mendelian randomization study.

BACKGROUND: The effects of viral hepatitis (VH) on type 2 diabetes (T2D) remain controversial. AIM: To analyze the causal correlation between different types of VH and T2D using Mendelian randomization (MR). METHODS: Single nucleotide polymorphisms of VH, chronic hepatitis B (CHB), chronic hepatitis C (CHC) and T2D were obtained from the BioBank Japan Project, European Bioinformatics Institute, and FinnGen. Inverse variance weighted, MR-Egger, and weighted median were used to test exposure-outcome associations. The MR-Egger intercept analysis and Cochran's Q test were used to assess horizontal pleiotropy and heterogeneity, respectively. Leave-one-out sensitivity analysis was used to evaluate the robustness of the MR analysis results. RESULTS: The MR analysis showed no significant causal relationship between VH and T2D in Europeans [odds ratio (OR) = 1.028; 95% confidence interval (CI): 0.995-1.062, P = 0.101]. There was a negative causal association between CHB and T2D among East Asians (OR = 0.949; 95%CI: 0.931-0.968, P < 0.001), while there was no significant causal association between CHC and T2D among East Asians (OR = 1.018; 95%CI: 0.959-1.081, P = 0.551). Intercept analysis and Cochran's Q test showed no horizontal pleiotropy or heterogeneity (P > 0.05). Sensitivity analysis showed that the results were robust. CONCLUSION: Among East Asians, CHB is associated with a reduced T2D risk, but this association is limited by HBV load and cirrhosis. Although VH among Europeans and CHC among East Asians are not associated with the risk of T2D, focusing on blood glucose in patients with CHC is still relevant for the early detection of T2D induced by CHC-mediated pathways of hepatic steatosis, liver fibrosis, and cirrhosis.

Research status and hotspots of autoimmune gastritis: A bibliometric analysis.

BACKGROUND: As an emerging potential risk factor for gastric cancer, autoimmune gastritis (AIG) has garnered increasing attention from researchers. AIM: To analyze the research overview and popular topics in the field of AIG using bibliometrics. METHODS: Relevant publications on AIG in the Web of Science Core Collection were collated, and data visualization and analysis of the number of publications, countries, institutions, journals, authors, keywords, and citations were performed using software such as VOSviewer, CiteSpace, and Scimago Graphic. RESULTS: In total, 316 relevant articles were included in the analysis. From 2015 to 2022, the number of publications increased annually. The countries, institutions, authors, and journals with the highest number of publications in this field were Italy, Monash University, Toh BH, and Internal Medicine. The main keywords used in this field of research were pathogenesis, Helicobacter pylori, autoantibody, parietal cell antibody, atrophic gastritis, classification, diagnosis, autoimmune disease, risk, cancer, gastric cancer, vitamin B12 deficiency, and pernicious anemia. The following directions may be popular for future research: (1) The role of Helicobacter pylori in the pathogenesis of AIG; (2) diagnostic criteria for AIG and reference values for serum antibodies; (3) comorbidity mechanisms between AIG and other autoimmune diseases; (4) specific risks of AIG complicating gastric and other cancers; and (5) the role of vitamin B12 supplementation in patients with early-stage AIG. CONCLUSION: This bibliometric analysis reported on popular topics and emerging trends in AIG, with diagnosis and prognosis being research hotspots in this field.

A novel aptamer beacon for rapid screening of recombinant cells and in vivo monitoring of recombinant proteins.

Recombinant protein drugs, which are typically produced by mammalian host cells, have been approved for the treatment of a range of diseases. Accordingly, systems for selecting recombinant cell lines with efficient protein expression and for testing the content of recombinant proteins in vivo are crucial to the large-scale production and application of protein-based therapeutic drugs. In this study, we designed three aptamer beacons to detect His-tag, a common label of recombinant proteins. We found that all three beacons could specifically and quantitatively measure the His-tagged recombinant proteins with a short reaction time. Among these three beacons, the 6H5-MU beacon had the highest sensitivity for His polypeptides with a detection limit of 250 ng/mL and the shortest detection time within 1 min. Furthermore, we established a rapid and highly effective recombinant cell line construction system, which could obtain monoclonal cell lines with high yields of target proteins within 21 days, by combining 6H5-MU with pSB, a novel plasmid composed of a Sleeping Beauty transposase and a transposon. Finally, 6H5-MU also discriminately tested the serum concentration of His-tagged recombinant proteins in vivo, with consistent results compared to enzyme-linked immunosorbent assay (ELISA). We thus established a rapid and high-throughput method for generating recombinant cell lines and in vivo monitoring of recombinant protein levels, thereby providing a new platform for the development and preparation of recombinant protein drugs. KEY POINTS: • The 6H5-MU aptamer beacon rapidly and accurately binds to His-tagged recombinant proteins. • A system for rapid and high-throughput generation of recombinant cell lines is established using 6H5-MU and pSB. • 6H5-MU allows in vivo monitoring of recombinant protein levels.

Long-term fasting glucose variability and risk of cancer in patients with type 2 diabetes mellitus: A retrospective population-based cohort study in Shanghai.

BACKGROUNDS: Fasting blood glucose (FBG) variability may make an impact on adverse events in patients with diabetes mellitus. However, the association between long-term changes in FBG and cancer remains unclear. We aimed to investigate this association in a large-scale longitudinal study. METHODS: Data were collected from 46 761 patients with type 2 diabetes mellitus aged 20-80 years who participated in the Diabetes Standardized Management Program in Shanghai, China. We adopted four indicators, including standard deviation (SD), coefficient of variation (CV), variation independent of the mean (VIM), and average real variability (ARV) to describe FBG variability. Adjusted multivariable Cox regression analyses and restricted cubic splines were used to investigate the association between long-term FBG variability and cancer risk. We also determined the interactive effect of FBG variability with hypertension and FBG-mean with hypertension on cancer risk, respectively. RESULTS: In this study, we confirmed 2218 cancer cases (51.1% male) over a median follow-up of 2.86 years. In the multivariable-adjusted models, participants in the highest quartile of FBG variability had an increased risk of cancer compared with those in the lowest quartile. The nonlinear association was found when using FBG-VIM, FBG-ARV, and FBG-SD in restricted cubic spline plots. There was a significant interaction effect of FBG variability with hypertension on cancer, whereas the effect of FBG-mean with hypertension did not attain significance. CONCLUSIONS: Our retrospective cohort study demonstrated a positive association between the long-term changes in FBG and cancer risk in patients with type 2 diabetes mellitus. FBG variability may independently predict cancer incidence.

Pembrolizumab-induced Stevens-Johnson syndrome in advanced squamous cell carcinoma of the lung: A case report and review of literature.

BACKGROUND: For advanced lung squamous cell carcinoma, immune checkpoint inhibitors (ICIs) have been regarded as one of the optimal therapies. While immune-related adverse events (irAEs) are common in ICI treatment, cutaneous toxicities are among the most common irAEs. Most immune-related skin toxicity grades are low, and the prognosis is good. However, Stevens-Johnson syndrome (SJS) is a rare but extremely severe cutaneous adverse drug reaction with high mortality. CASE SUMMARY: We report a rare case of SJS induced by pembrolizumab. The case involved a 68-year-old female who was diagnosed with advanced squamous cell carcinoma of the lung. SJS appeared after one cycle of immunotherapy combined with chemotherapy. After treatment with prednisone hormone symptoms, anti-infection, gamma globulin, and antipruritic agents, the skin toxicity of the patients gradually decreased and eventually disappeared. Although the antitumor treatment was stopped due to serious adverse reactions, the tumor of the patient remained stable for nearly half a year after one cycle of immune therapy combined with chemotherapy, which also corroborates the delayed effect of immunotherapy. CONCLUSION: We believe our report can provide some references for the treatment of SJS and the treatment of immune-related adverse reactions.

A scoping review of intervention components of school-based oral health-related behavioural interventions using the Theoretical Domains Framework.

The aim of this study was to review the intervention components of school-based oral health-related behavioural interventions using the Theoretical Domains Framework (TDF). We identified relevant papers from the review of Cooper et al., and these papers came from both the original inclusion and exclusion article lists. We also modified and updated their search strategies (2013 - April 2019). The 53 included papers reported on 79 interventions (experimental groups = 57 interventions, control groups = 22 interventions). Most of the papers used three to nine domains (average = 5.6) in their experimental interventions, and the most commonly used domains were 'knowledge,' 'skills,' 'social influences,' and 'environmental context and resources.' Considering the complexity of intervention components in one programme, there is no one specific domain or domain set that can determine the success of behavioural interventions. The design of future programmes should be guided by a complex intervention methodology. However, the best combination set might not exist, and the choice of domains should depend on local context or resources. This study can be used as a resource for identifying previous papers, which have used the same domains.

[Current situation and problems of national standards for Chinese medicinal materials].

To learn the current situation and strengthen the management of national standards for Chinese medicinal materials, we sorted out the relevant national standards. According to incomplete statistics, there are 1 185 kinds of Chinese medicinal materials, including 1 024 kinds of plant medicines, 106 kinds of animal medicines, and 54 kinds of mineral medicines, in addition to ethnic medicinal materials with different functions. The relevant standards include 819 Pharmacopoeia standards, 342 standards issued by the Ministry of Health or National Medicinal Products Administration, 7 standards for new medicinal materials, and 17 standards for imported medicinal materials. In this paper, the sources of standards as well as the distribution of families and genera and the distribution of medicinal parts of medicinal materials are analyzed. The suggestions are as follows:(1)to improve the coordination among different national standards of Chinese medicinal materials;(2)to improve the standardization and controllability of relevant standards;(3)to revise the issued standards for Chinese medicinal materials(including Tibetan, Uygur, and Mongolian medicinal materials).

Up-regulation of BTLA expression in myeloid dendritic cells associated with the treatment outcome of neonatal sepsis.

Dentritic cells (DCs) dysfunction has been verified detrimental for sepsis and B and T lymphocyte attenuator (BTLA) is an immune-regulatory receptor shown to be associated with DCs dysfunction. However, the role of BTLA expression in myeloid DCs (mDCs) in neonatal sepsis is unknown. In the current study, we found BTLA-expressing mDCs were elevated in neonates with sepsis and the BTLA expression level in mDCs was positively correlated to the severity of sepsis. The presence of BTLA negatively regulated the phagocytosis capacity and bactericidal ability of mDCs as well as the maturation markers expression of mDCs. Our data also showed BTLA+mDCs shifted into an anti-inflammatory phenotype with decreased expression of IL-6, TNF-α and IL-12, but increased IL-10. in addition, we found BTLA expression indeedly altered the mDCs allo-stimulatory capacity. Therefore, BTLA expression in mDCs could be a useful predictive marker for neonatal sepsis and targeting BTLA expression in mDCs may be a new therapeutic strategy.

Irisin, an exercise myokine, potently suppresses tumor proliferation, invasion, and growth in glioma.

Glioblastoma multiforme is the most common and aggressive glial tumor with poor prognosis. Importantly, effective treatment options for glioblastoma are unmet needs. Obesity and low physical activity have been linked with a high risk of cancer, and exercise is related to delayed cancer development and progression. Epidemiological studies have revealed a correlation between exercise and the survival rate of patients with glioblastoma. Nevertheless, the mechanisms by which exercise exerts its anticancer effects in glioblastoma remain unclear. Here, we found that irisin, an exercise-induced myokine, induced G2 /M cell cycle arrest and increased p21 levels in glioblastoma cells, leading to the inhibition of cell proliferation. In addition, irisin inhibited glioblastoma cell invasion by upregulating TFPI-2 and even reversed the aggressive tumor phenotype promoted by co-cultivation with cancer-associated adipocytes. Furthermore, irisin retarded xenograft glioblastoma tumor growth, and radiolabeled irisin demonstrated specific tumor-targeting capability in vivo. Therefore, this study identified one potential molecular mechanism by which exercise prevents cancer progression via irisin. Intriguingly, irisin has the potential to be developed as a molecular imaging and therapeutic anticancer agent.

Comparisons of tissue distributions and health risks of perfluoroalkyl acids (PFAAs) in two fish species with different trophic levels from Lake Chaohu, China.

Perfluoroalkyl acids (PFAAs) are a type of persistent organic pollutants that are widely distributed in multiple environmental media and organisms and have a teratogenic effect on and toxicity to animals and humans. The residual levels of seventeen PFAAs in the tissues of two regular consumption fish species, Culter erythropterus and Aristichthys nobilis in Lake Chaohu were measured by a high-performance liquid chromatograph - mass spectrometer (HPLC-MS). The distributions of PFAAs and the effect of the lipid contents were analyzed, and the health risks of typical PFAAs were evaluated. The results showed that perfluorohexanoic acid (PFHxA) was the predominant contaminant (80.50 ±â€¯58.31 ng/g and 19.17 ±â€¯12.57 ng/g wet weight, ww), followed by perfluorooctanesulfonic acid (PFOS) (55.02 ±â€¯34.82 and 14.79 ±â€¯6.24 ng/g, ww) in both fish. The level of total PFAAs was the highest in the liver tissues of Culter erythropterus (359.87 ng/g, ww) and the lowest in the kidney tissues in A. nobilis (10.06 ng/g, ww). Due to the higher trophic level of C. erythropteru, the total PFAA concentrations were significantly higher in all tissues than those in A. nobilis. Liver muscle ratio of C. erythropteru was the highest, indicating the most accumulation in the liver. The concentrations of PFAAs in fish tissues were influenced by the lipid content, resulting in a difference between the lipid-normalized concentrations and the wet weight concentrations of the PFAAs. The non-carcinogenic risks of PFOS were higher than those of PFOA through the ingestion of C. erythropterus and A. nobilis. Both the carcinogenic and non-carcinogenic risks of C. erythropterus were greater than those of A. nobilis, and fish tissue intake could cause an increasing of risks up to 60%, indicating that long-term and large amount ingestion of carnivorous fish and related tissues with higher trophic level, such as C. erythropterus should be avoided.

Reevaluation of a rightward shift in colorectal cancer: A single-center retrospective study in Tianjin.

OBJECTIVES: Some Western reports have shown a proximal shift in colorectal cancer (CRC), but there are few studies in China. This study aimed to provide more information for the management and screening of CRC by investigating trends in the anatomic distribution of CRC among the Chinese population in recent years. METHODS: A retrospective study was conducted on patients with CRC admitted to the Digestive Endoscopy Center of Tianjin Medical University General Hospital between January 2000 and December 2017. Patients were divided into a left-sided colorectal cancer (LSCRC) group and a right-sided colon cancer (RSCC) group. The detection rates of LSCRC and RSCC based on patients' age and sex, and on the time periods were analyzed. RESULTS: A total of 2319 cases were diagnosed with CRC among 75 183 consecutive patients. The prevalence of CRC showed a significant reduction from 2000-2008 to 2009-2017 (3.8% vs 2.7%, P < .001). The proportion of RSCC presented a downtrend from 2000-2008 to 2009-2017 (40.6% vs 37.7%, P > .05). There were slightly more RSCCs in female patients than in male patients, with no significant difference (40.9% vs 36.5%, P > .05). The proportion of RSCC in patients aged ≥50 years was similar to that in younger patients. The alarming symptoms between LSCRC and RSCC showed a significant difference (P < .05). CONCLUSIONS: In the present study, the prevalence of CRC declined significantly with time. However, there did not appear to be a rightward shift in CRC among the patients in Tianjin over the past 18 years.

Effects of fluorescent dissolved organic matters (FDOMs) on perfluoroalkyl acids (PFAAs) in lake and river water.

This study presents the effects of fluorescent dissolved organic matters (FDOM) on perfluoroalkyl acids (PFAAs) in western Lake Chaohu and its inflow rivers. The surface water samples from the 27 sites in western Lake Chaohu and its inflow rivers were collected in March and September 2013. The contents of PFAAs and the FDOM in the water samples were measured by a high-performance liquid chromatograph - mass spectrometer (HPLC-MS) and by a fluorescence spectrophotometer, respectively. The temporal-spatial distributions of PFAAs and FDOM, as well as their interrelationships, were investigated. Eleven PFAA components were detected, and the mean concentration of total PFAAs (TPFAAs) in western Lake Chaohu and its inflow rivers were 12.93 ±â€¯5.19 ng/L and 11.84 ±â€¯9.50 ng/L, respectively. PFOA was the predominant contaminant in two regions (7.13 ±â€¯3.07 ng/L and 4.30 ±â€¯2.14 ng/L) followed by PFHxA (1.72 ±â€¯0.80 ng/L and 1.42 ±â€¯1.41 ng/L) and PFBA (1.44 ±â€¯0.78 ng/L and 1.37 ±â€¯0.78 ng/L). The mean concentration of total FDOM in western Lake Chaohu and its inflow rivers were 220.0 ±â€¯40.30 µg quinine sulfate units (Q.S.)/L and 406.3 ±â€¯213.1 µg Q.S./L, respectively. The significant, positive correlations were observed between the PFAAs and FDOMs in both the lake area and the inflow rivers. However, no significant correlation was observed between PFAAs and the dissolved organic carbon (DOC) in the lake area. This finding indicated that the residues and distributions of PFAAs were significantly dependent on the compositions of dissolved organic matters (DOM) and not on the total content of DOM.

Clinical correlation of B7-H3 and B3GALT4 with the prognosis of colorectal cancer.

AIM: To investigate the expression and clinical significance of B7 homolog 3 (B7-H3) and ß-1,3-galactosyltransferase-4 (B3GALT4) in colorectal cancer (CRC) patients. METHODS: Using tissue microarray, we identified the expression of B7-H3 and B3GALT4 in 223 CRC patient samples by immunohistochemistry and evaluated the possible correlation between B7-H3 and B3GALT4 and clinical outcomes. Further, the mRNA and protein expression were identified to establish the regulatory relationship of B7-H3 with B3GALT4 in vitro. RESULTS: A significant positive correlation between B7-H3 and B3GALT4 was observed in CRC specimens (r = 0.219, P = 0.001). High expression of B7-H3 was identified as a significant independent predictor of poor overall survival (OS) [hazard ratio (HR) = 1.781; 95%CI: 1.027-3.089; P = 0.040]. Moreover, high expression of B3GALT4 was also recognized as an independent predictor of inferior OS (HR = 1.597; 95%CI: 1.007-2.533; P = 0.047). Additionally, CRC patients expressing both high B7-H3 and high B3GALT4 contributed to a significant decrease in OS (HR = 2.283; 95%CI: 1.289-4.042; P = 0.005). In CRC cell lines with stable expression of high B7-H3, the mRNA and protein expressions of B3GALT4 were significantly upregulated. Similarly, the expression of B3GALT4 was significantly reduced when expression of B7-H3 was knocked down. CONCLUSION: The expression of B3GALT4 in CRC is positively correlated with B7-H3 expression in vitro. B7-H3/B3GLAT4 may be used as dual prognostic biomarkers for CRC.

[Nursing Care Experiences of Periwound Moisture-Associated Dermatitis After Simultaneous Pancreas-Kidney Transplantation].

Simultaneous pancreas-kidney (SPK) transplantation is the primary surgical treatment for type I diabetes mellitus with end-stage renal disease. However, this transplant surgery has a high-risk of surgical complications, including duodenal anastomotic leakage, which may lead to pancreas transplantation failure if the leakage worsens. This case report describes a patient who suffered from duodenal anastomotic leakage after SPK transplantation. The digestive enzymes eroded the wound and skin around the wound, resulting in periwound moisture-associated dermatitis. During the period of nursing care, the wound-care intervention was determined by interdisciplinary cooperation. In our case report, the periwound moisture-associated dermatitis healed completely under inter-hospital care. In clinical nursing practice, periwound moisture-associated dermatitis should be cared in combination with macerated wounds. We suggest the following: (1) control the moisture source; (2) use advanced dressings as the primary dressing with sterile gauze as a secondary dressing and silver antimicrobial dressings for infected wounds; (3) consider using negative pressure wound therapy for complicated chronic wounds; and (4) use a pH-neutral skin cleanser with non-woven gauze to clean the periwound skin and keep the skin clean and dry. Finally, we suggest isolating and protecting the skin with No Sting Barrier Film and a hydrocolloid dressing. We hope this nursing care experiences serves as a reference for the nursing care of periwound moisture-associated dermatitis resulting from duodenal anastomotic leakage during / after SPK transplantation.

Resuscitation with hydroxyethyl starch 130/0.4 attenuates intestinal injury in a rabbit model of sepsis.

OBJECTIVE: Improvement of mucosal barrier function and reduction of bacterial translocation are important in the management of sepsis. The mechanisms that underlie the protective effects of colloids on the intestinal mucosal barrier are unclear. The study aims to investigate the effect of fluid resuscitation with hydroxyethyl starch (HES) 130/0.4 against intestinal mucosal barrier dysfunction in a rabbit model of sepsis. MATERIALS AND METHODS: Thirty healthy rabbits were randomly and equally divided into a sham-operated control, a sepsis model, or a sepsis + HES treatment group. The sepsis model and sepsis + HES treatment groups were subjected to a modified colon ascendens stent peritonitis (CASP) procedure to induce sepsis. Four hours after the CASP procedure, fluid resuscitation was performed with 6% HES 130/0.4. Arterial and superior mesenteric vein blood samples were collected 4 and 8 h after the CASP procedure for blood gas analysis and measuring tumor necrosis factor-α, interleukin-10, and D-lactate levels. The rabbits were euthanized 8 h after CASP, and sections of the small intestine were stained to evaluate histopathological changes. RESULTS: Respiratory rate and blood pressure were stable during the resuscitation period. Fluid resuscitation with 6% HES 130/0.4 alleviated pathological changes in the abdominal cavity, improved blood gas parameters and inflammatory mediator levels, decreased plasma D-lactate levels, and reduced intestinal mucosal injury compared with the non-treated sepsis model. CONCLUSIONS: Fluid resuscitation with 6% HES 130/0.4 protects against intestinal mucosal barrier dysfunction in rabbits with sepsis, possibly via mechanisms associated with improving intestinal oxygen metabolism and reducing the release of inflammatory mediators.

Polyacetylated labdane-type diterpenoids, ptychantins P-R from Chinese liverwort Ptychanthus striatus.

Three new polyacetylated labdane diterpenoids ptychantins P-R (1-3) and four known compounds (4-7) were isolated from an EtOH extract of the Chinese liverwort Ptychanthus striatus (Lehm. & Lindenb.) Nees. Their structures were established by extensive analysis of spectroscopic data (IR, UV, HRESIMS, 1D NMR, and 2D NMR).

Notolutesins A-J, dolabrane-type diterpenoids from the Chinese liverwort Notoscyphus lutescens.

Ten new dolabrane-type diterpenoids, notolutesins A-J (1-10), were isolated from the Chinese liverwort Notoscyphus lutescens, along with four known compounds. The structures of the new compounds were established on the basis of extensive spectroscopic data, and that of 1 was confirmed by single-crystal X-ray crystallography. The absolute configuration of 1 was determined by comparing its experimental and calculated electronic circular dichroism spectra. All of the isolates were evaluated for their cytotoxicity against a small panel of human cancer cell lines, and compound 1 exhibited an IC50 value of 6.2 µM against the PC3 human prostate cancer cell line.

[Expression of BCR/ABL fusion gene in circulating endothelial cells from chronic myelogenous leukemia patients and its clinical significance].

Several studies have shown that the tumor endothelial cells are different from the normal tissue endothelial cells. These tumor endothelial cells may contribute to tumor neo-vasculogenesis. This study was purposed to analyze the biologic features and determine the expression level of CD133 and BCR/ABL fusion gene in circulating endothelial cells (CEC) isolated from peripheral blood of CML patients, as well as to investigate the role of CEC in disease progression. Mononuclear cells were isolated from peripheral blood by density gradient centrifugation; CEC were sorted by MACS and harvested in the endothelial growth medium. The morphologic features of CEC were observed by microscopy, the cell growth rate was calculated by cell counting, and the cells were identified by immunofluorescence staining for the expression of CD31,CD34,VWF and CD133. The expression of BCR/ABL fusion gene was examined by FISH in 12 CML patients. The results indicated that the isolated CEC displayed the typical cobble-stone morphology. These cells could be identified by the positive immunofluorescence staining for CD31, CD34 and VWF, and showed more increased proliferative potential as compared to that of healthy donors. It was found that the positive rate of CD133 was 31.29% in CML patients, which was significantly different from that of healthy donors (P < 0.05). In 12 CML patients, CEC carried the same chromosome aberration as the leukemia cells (10.77%). Higher expression level of CD133 and BCR/ABL fusion gene positively correlated with progression of disease. It is concluded that the CEC may participate in invasion and angiogenesis in patients with CML and possibly correlate to the spreading and progression of the disease.

[Clinical investigation of homoharringtonine in combination with all-transretinoic acid and arsenic trioxide for acute promyelocytic leukemia].

OBJECTIVE: To study the clinical outcome, adverse effect and treatment cost of homoharringtonine (HHT) in combination with all-trans retinoic acid (ATRA) and arsenic trioxide (AS2O3) for newly diagnosed with patients acute promyelocytic leukemia (APL). METHODS: Clinical data of treatment of newly diagnosed patients with APL in experimental group (HHT + ATRA + AS2O3, n = 14) and control group \[Idarubicin (IDA) + ATRA + AS2O3, n = 21\] were analyzed retrospectively. The therapeutic effects, side effects and costs during induction therapy were compared between the two groups. RESULTS: (1) The complete remission (CR) rate were 92.9% (13/14) and 95.2% (20/21) in experimental group and control group, respectively. The time to achieve CR were (28.1 ± 3.8) and (31.7 ± 4.2) days, respectively (P > 0.05). The negative rate of PML-RARα fusion gene at the time of CR were 76.9% (10/13) and 75.0% (15/20), respectively, and that in CR patient at the end of the first cycle treatment were 100.0% (13/13) and 95.0% (19/20), respectively (P > 0.05). (2) 5-year overall survival (OS) rate were (92.6 ± 0.6)% and (89.9 ± 0.5)%, respectively (P > 0.05), 5-year disease free survival (DFS) rate were 100.0% and (86.8 ± 0.6)%, respectively (P > 0.05). (3) During induction therapy, the incidence of infection in experimental and control group were 23.1% (3/13), 60.0% (12/20), respectively (P < 0.05). The amount of platelet transfusion were (54.7 ± 29.6) and (76.5 ± 25.6) units, respectively (P > 0.05), and that of fresh frozen plasma were (1157.1 ± 238.4) and (1423.5 ± 324.6) ml, respectively (P > 0.05). The total medical costs (excluding HHT and IDA) in experimental and control group were (36074.9 ± 1245.6) and (50564.5 ± 3658.4)CNY, respectively (P < 0.05). CONCLUSION: HHT in combination with ATRA and AS2O3 regimen for newly diagnosed APL has a better efficacy, a higher long-term survival rate, and a lower costs, which is one of the reasonable choice.
