Meta analysis of the relationship between DEPDC5 gene polymorphism and hepatocellular carcinoma susceptibility / 中国医师杂志

Objective:To systematically evaluate the relationship between rs1012068 and rs5998152 single nucleotide polymorphisms of DEPDC5 gene and susceptibility to hepatocellular carcinoma (HCC).Methods:Up to October 31, 2022, PubMed, Embase, Scopus, Web of Science and China National Knowledge Internet (CNKI) were used to search the relationship between rs1012068, rs5998152 and susceptibility to HCC. The odds ratio (OR) values and 95% CI of the five genetic models were calculated, and the RevMan5.3 software was used for meta analysis. Results:A total of 12 articles were included in this study, including 11 articles about rs1012068 locus, including 2 609 patients with HCC and 8 171 controls, and 3 articles about rs5998152 locus, including 411 patients with HCC and 1 448 controls. The results of meta analysis showed that among the five genetic models of rs1012068 locus, allele pattern (G vs T: P=0.02), dominant pattern (GG+ TG vs TT: P=0.01) and heterozygote pattern (TG vs TT: P=0.009) were significantly different between the case group and the control group. In homozygous mode (GG vs TT: P=0.05) and recessive mode (GG vs TG+ TT: P=0.08), there was no correlation between rs1012068 gene polymorphism and susceptibility to HCC. Among the five genetic models of rs5998152 locus, allele model (C vs T: P=0.03), dominant model (CC+ TC vs TT: P=0.001) and heterozygous model (TC vs TT: P<0.000 01) were significantly different between case group and control group. There was no correlation between rs5998152 gene polymorphism and susceptibility to HCC in recessive model (CC vs TC+ TT: P=0.31) and homozygous model (CC vs TT: P=0.09). Conclusions:There is a correlation between rs1012068 locus and susceptibility to HCC in allele model and dominant gene model, which is a genetic factor promoting tumorigenesis. The allele pattern, dominance pattern and heterozygote pattern of rs5998152 locus can increase the risk of liver cancer, but no correlation was found in other patterns.

Prognosis of clonal chromosomal abnormalities in Philadelphia negative metaphases cells in chronic myeloid leukemia with tyrosine kinase inhibitor therapy / 中华血液学杂志

Objective: To investigate the characteristics and prognosis of clonal chromosomal abnormalities appearing in Philadelphia negative metaphases (CCA/Ph(-)) cells in chronic myeloid leukemia (CML) with tyrosine kinase inhibitor (TKI) therapy. Methods: The clinical data of 30 cases with CCA/Ph(-) during TKI treatment in Henan Cancer Hospital from August 2007 to July 2017 were retrospectively analyzed. The univariate factor was analyzed by Kaplan-Meier method. Multiple-factor was analyzed by Cox proportional risk model. Results: Of the 30 cases, 19 (63.3%) were males. At the first detection of CCA/Ph(-) the median age was 44 (rang 14-68) years old and the median treatment of TKI was 13 (rang 2-94) months. The clones proportion of first detected CCA/Ph(-)≥ 50% was found in 18 (60.0%) cases. TKI treatment for 3 months with BCR-ABL(IS) less than 10% was seen in 14 (46.7%) patients. 63.3% (19/30) of CCA/Ph(-) was transient (only one time) and 36.7% (11/30) was repeated (≥2 times) . Trisomy 8 dominant accounted for 60.0% (18/30) , -7/7q- for 13.3% (4/30) , loss of chromosome Y 6.7%. With a median of follow-up 50 months, 76.7% (23/30) cases were in complete cytogenetic response (CCyR) ; 63.3% (19/30) in major molecular response (MMR) , 43.3% (13/30) in undetectable minimal residual disease (UMRD) . The median event-free survival rate of (EFS) were 44 months, and 2-year and 5-year EFS were (82.1±7.3) % and (52.4±12.8) %, respectively. The median overall survival (OS) were 50 months, and 2-year and 5-year OS rates were (92.6±5.0) % and (77.2±14.7) %, respectively. Univariate analysis shows that the 2-year EFS of who in males, more than 2 times CCA/Ph(-), BCR-ABL(IS)>10% at 3 months after TKI were significantly lower than women, transient CCA/Ph(-), and BCR-ABL(IS)≤10% (P<0.05) . The 2-year OS rate in whom the occurrence frequency of CCA/Ph(-) more than twice was significantly lower than those with transient CCA/Ph(-) (P<0.05) . Multivariate analysis showed that CCA/Ph(-) was an independent risk factor (RR=4.741, 95%CI 1.21-18.571, P=0.018) for EFS in CML patients. Conclusion: Trisomy 8, -7/7q-, and -Y were the most common CCA/Ph(-) during TKI treatment, with high clones proportion of ≥50%. CCA/Ph(-) mainly occurred transiently or was permanent occasionally. CCA/Ph(-) recurrence (≥2 times) was an independent risk factor for EFS and OS in CML with TKI.

Effect of nilotinib on pregnancy outcome in female patients with chronic myeloid leukemia / 中华血液学杂志

Objective: To observe the pregnancy outcome among patients with chronic myeloid leukemia (CML) treated with Nilotinib (NIL) . Methods: Clinical data of pregnancy delivery in CML patients treated with NIL from March 2015 to January 2019 were retrospectively collected. Results: A total of 11 patients were recruited with median pregnancy age 28 (25-40) years. The median duration of NIL treatment before pregnancy was 34 (3-48) months. There were 12 pregnancies, included 2 planned ones and 10 (83.3%) unplanned. In the 10 unplanned patients, 9 (90.0%) received NIL 600 mg/d. The median exposure time were 4 (4-7) weeks. In eight patients with delivery outcomes, 5 cases had well-developed babies, 2 had spontaneous abortion and 1 case with an baby of syndactyly deformity, whose mother was exposed to NIL 600 mg/d for 7 weeks in the early trimester of pregnancy. Seven infants were 4 boys and 3 girls with the median height at birth 50 (41-54) cm and median weight 3.2 (3.0-4.6) kg. They all grew with a normal pattern and well developed. Now the median age is 19 (4-41) months. The disease status during 12 pregnancies included 3 cases in CMR, 2 cases in MR(4.0), 3 cases in MMR, 4 cases not acquiring MMR. The median time of drug discontinuation was 35 (15-36) weeks during pregnancy. No patient lost CHR during this period. Conclusions: Female CML patients exposed to NIL 600 mg/d for 4 weeks in early pregnancy can give birth to normal babies, but there is still a risk of spontaneous abortion and congenital malformations.

Correlation between cystatin C and atherogenic index of plasma change in hypertensive patients / 预防医学

Objective To understand the correlation and clinical significance between cystatin C and atherogenic index of plasma change in hypertensive patients. Methods At the Quzhou City central hospital between 2014 and 2015, 526 cases of hypertensive patients as hypertensive group and 546 cases of people with normal blood pressure in the healthy check-up as normal blood pressure group were investigated with physical examination, blood biochemical index detection and the serum cystatin C level detection. The analysis of the relationship between the serum cystatin C level and atherogenic index of plasma among two groups was done. Results The evidence that the serum cystatin C level between hypertensive group and normal blood pressure group shows respectively as: 1.12±0.44 (mg/L) and 0.81±0.22 (mg/L), atherogenic index of plasma shows respectively as:0.68±0.03 and -0.22±0.02, both differences were statistically significant (P<0.01) . As the serum cystatin C level increased, the risk of hypertension increased (OR=20.06, 95％CI: 12.67-31.76) . Plasma arteriosclerosis index in hypertensive group was correlated with systolic blood pressure, body mass index, total cholesterol, triglyceride, high-density lipoprotein, LDL cholesterol, and uric acid level respectively, all differences were statistically significant. In addition to the above indicators, the serum cystatin C level in hypertensive group was correlated with serum creatinine level (all P<0.05) . Conclusion The serum cystatin C level and plasma arteriosclerosis index in patients with hypertension both were higher than those with normal blood pressure. These two indicators were correlated with systolic blood pressure and multiple blood lipid indicators. They could be used to monitor arteriosclerosis and target organ damage in patients with hypertension.

The molecular-cytogenetic characterization and tyrosine kinase inhibitors efficacy in newly diagnosed chronic phase CML patients with variant Philadelphia chromosomes / 中华血液学杂志

Objective: To investigate the molecular-cytogenetic characterization and impact on tyrosine kinase inhibitors (TKIs) therapy in chronic phase of chronic myeloid leukemia (CML-CP) patients with variant Ph chromosome (vPh). Methods: The clinical data of 32 patients with vPh chromosomes were collected and compared with 703 patients with typical Ph chromosome in newly diagnosed CML-CP who were on first-line imatinib (IM) and with BCR-ABL transcript of P210. Results: There was no significant difference in demographic and hematological characteristics between vPh and classic Ph patients. 3(9.4%) of the 32 vPh cases were simple variant translocations. Among the remaining 29 cases with complex variant translocations, 28 cases (87.5%) involved 3 chromosomes, and only 1 (3.1%) involved 4 chromosomes. Except for 8, 15, 18, X, and Y chromosomes, the other chromosomes were involved. The frequency of chromosome 12q(15.5%) and 1p (12.1%) were higher involved. The most common FISH signal pattern was 2G2R1Y (74.1%), followed by 1G1R2F (14.8%), 2G1R1Y (3.7%), 1G2R1Y (3.7%), 1G1R1Y (3.7%). The comparison of complete cytogenetic response (CCyR) (P=0.269), major molecular response (MMR) (P=0.391) were carried out between simple and complex mechanisms, without difference. Compared with the classic Ph, the patients with vPh had higher IM primary resistance rate (χ2=3.978, P=0.046), especially primary hematological resistance (χ2=7.870, P=0.005), but the difference of CCyR (χ2=0.192, P=0.661), MMR (χ2=0.822, P=0.365), EFS (χ2=0.509, P=0.476), OS (χ2=3.485, P=0.062) were not statistically significant, and multivariate analysis showed that the presence of vPh did not affect OS (RR=0.692, 95%CI 0.393-1.765, P=0.658)、EFS (RR=0.893, 95%CI 0.347-2.132, P=0.126) and PFS (RR=1.176, 95%CI 0.643-2.682, P=0.703). Conclusion: CML-CP patients with vPh and classic Ph had similar demographic and hematological characteristics. Except for 22q11, 9q34, the frequency of chromosome 12q and 1p were higher involved. The most common FISH signal pattern was 2G2R1Y, and different mechanisms had no impact on TKIs therapy. Compared with cases with classic Ph chromosomes, the patients with vPh chromosomes had higher risk of IM primary resistance, especially primary hematological resistance, which can obtain deeper molecular response quickly after changing to second-generation TKIs and didn't affect long-term outcomes and OS.

Effect of stopping tyrosine kinase inhibitors during pregnancy on disease status and reproductive outcomes among patients with chronic myeloid leukemia / 中华血液学杂志

Objective: To explore the pregnancy outcome and disease status among patients with chronic myeloid leukemia (CML) treated with tyrosine kinase inhibitor (TKI) when they stopped TKI treatment during pregnancy. Methods: The clinical characteristics, reproductive outcomes and disease status of the patients who stopped TKI due to pregnancy between November 2004 to November 2017 were retrospectively collected. Results: A total of 14 CML patients in chronic phase (CML-CP), 12 patients were Sokal-low-risk. The median time of TKI treatment was 46.5 (15-123) months before the drug was stopped. The median age at the time of pregnancy was 29 (24-32) years. The median time of TKI exposure was 4 (0-9) weeks in 12 accidental pregnancies. Outcomes were available for 13 pregnancies, 9 cases (69.2%) delivered healthy babies, 1 case (7.7%) delivered polydactylia malformation baby, 3 cases (23.1%) had spontaneous abortion. The last one was still in pregnancy (no organ malformations were observed in color Doppler ultrasound). At the end of the follow up date, 10 children developed normal, the median age was 14 (0.7-65) months. Of the 14 patients who stopped TKI, 7 in complete molecular response (CMR), 3 in MR(4) (BCR-ABL(IS) <0.01%, ABL transcript >10 000), 2 in major molecular response (MMR), 2 in complete cytogenetic response (CCyR). The median time of TKI discontinuation during pregnancy was 33.5 (4-40) weeks. At the end of pregnancy, 4 cases were in CMR, 4 in MR(4), 1 in MMR and 4 in CCyR. No patients lost CCyR and complete hematologic remission. Conclusions: During the treatment of imatinib and Nilotinib, unplanned pregnancy may have a normal infant, but may lead to spontaneous abortion and congenital malformations. Female of CML-CP who had sustained and stable MMR at least 24 months and Sokal-low-risk had higher safety factor discontinued TKI during pregnancy, but still had a risk of increasing tumor load, so monitored the level of BCR-ABL of peripheral blood monthly during pregnancy is necessary.

Clinical analysis of six cases with the de novo glomerulitis after allogeneic hematopoietic stem cell transplantation / 中华血液学杂志

Objective: To explore the occurrence, clinical characteristics, diagnosis and treatment of glomerulitis after allogeneic hematopoietic stem cell transplantation (allo-HSCT). Methods: Analysis were carried out based on the clinical data of 6 patients with de novo glomerulitis following allo-HSCT hospitalized in Henan Tumor Hospital from January 2008 to December 2016, and the clinical manifestation, pathology, diagnosis, treatment and outcome were investigated. Results: The occurrence of glomerulitis was 1.26% (6/478). The median time was 447(272-1 495) d after allo-HSCT. Proteinuria and varying degrees of edema were present in all patients. Of the 6 patients, 4 patients with impaired renal function, 3 cases of hypertension, 5 cases of urine occult blood positive, 2 cases of hyperlipidemia. 5 patients underwent acute graft-versus-host disease (GVHD), 4 patients accompanied with chronic GVHD at diagnosis. Kidney pathology showed typical features of minimal change diseases in 1 patient, membranous nephropathy in 4 patients and mesangial proliferative glomerulonephritis in 1 case. Immunohistochemistry of glomerular lesions revealed that the immune complex deposition included IgG in 4 patients, C3 in 3 patients, IgM and C1q in 1 patient. Serum ANA was positive in 2 patients and serum IgG and IgM were in high level in 1 patient, respectively. Only 1 case was effective on glucocorticoid. 5 cases treated by low dose cyclophosphamide combined with mycophenolate mofetil (MMF), 2 cases achieved complete remission, and 3 cases were partial remission. Up to now, 2 cases died with lung infection, and 4 patients survived. Conclusion: The predominant pathological type of glomerulitis was membranous nephropathy. Low-dose cyclophosphamide combined with MMF was an effective treatment.

Activated changes of platelet ultra microstructure and plasma granule membrane protein 140 in patients with non-small cell lung cancer / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>Non-small cell lung cancer (NSCLC) is the leading cause of cancer mortality worldwide. Platelet activation may play an important role in pathologic progress in lung cancer. In this study, we aimed to clarify the influence of activated platelets on lung cancer generation and growth, and the relationship among these functional and ultrastructural changes of platelets and the severity of pathogenetic condition in these patients with NSCLC.</p><p><b>METHODS</b>One hundred and thirty-six cases of patients with pathologically confirmed NSCLC were included in this study. Fifty-four healthy people were enrolled as controls. The change of ultra microstructure and activity of blood platelets were observed under the transmission and scanning electron microscope. Simultaneous determination of plasma granule membrane protein 140 (GMP-140) was made.</p><p><b>RESULTS</b>Transmission electron microscopy showed remarkable changes of ultra microstructure of platelets in patients with NSCLC, including swelling, increase of a-granules, vesicles, and glycogenosome. Scanning electron microscopy showed many more surface processes and wrinkles on platelets in patients with NSCLC. The reference plasma levels of GMP-140 of healthy controls were (18.2 +/- 2.7) microg/L. The plasma levels of GMP-140 in patients with NSCLC were (47.8 +/- 12.3) microg/L, which were much higher than those of the controls. There was a medium positive correlation between plasma levels of GMP-140 and amount of a-granules (r = 0.514, P < 0.01) and a high positive correlation between plasma levels of GMP-140 and area of platelet (r = 0.84, P < 0.01) in patients with NSCLC. The Kaplan-Meier survival curve analysis showed significant shift to the left in patients with NSCLC whose a-granules per platelet were 19 or more compared to those 18 or less (Log rank statistic, chi(2) = 17.38, P < 0.01).</p><p><b>CONCLUSIONS</b>There are significant activated changes of ultra microstructure and increased activity of blood platelets in patients with NSCLC. These activated platelets may play an important role in the generation and growth of lung cancer. These changes can be used as a diagnostic index of severity, progression, and prognosis of NSCLC.</p>
