OBJECTIVETo analyze the clinical efficacy and possible influencing factors of autologous hematopoietic Stem cell transplantation (auto-HSCT) in the treatment of patients with multiple myeloma (MM).

METHODSClinical data of 40 MM patients received auto-HSCT in the Department of Hematology of Henan Cancer Hospital from September 2010 to November 2017 were retrospectively analyzed, the clinical curative efficiency was summarized and the related factors were analyzed.

RESULTSThe curative efficiency of the patients before transplantation was 9(22.5%) with complete remission(CR), 5(12.5%) with very good partial remission(VGPR), 26(65%) with partial remission(PR), respectively, one of them was PR after 3 recurrences. The curative efficiency after transplantation was 22(55%) with complete remission(CR), 12(30%) with very good partial remission(VGPR), 6(15%) with partial remission(PR), respectively. And 2 cases were CR after double transplantation. Median follow-up time was 28.4 (3.1 to 88) months,15 cases presented disease progression, 7 cases were dead, 3-year estimated progression-free survival(PFS) and overall survival(OS) rate were 45.1% and 82% respectively. Unvariate analysis showed that the OS was affected by ISS stage (P<0.05), CR and VGPR (P<0.05) after transplantation; PFS was affected by ISS stage (P<0.01), before transplantation induction therapy (27 cases with bortezomizomi or thalidomide) (P<0.05), disease risk stratification (6 cases in high risk group) (P<0.05) , CR and VGPR (P<0.05) before transplantation, CR and VGPR (P<0.01) after transplantation. Cox multivariate regression analysis showed that the independent prognostic factors for OS were ISS stage, CR and VGPR after transplantation; the independent prognostic factors for PFS were the CR, VGPR, ISS stage after transplantation and induction therapy before transplant.

CONCLUSIONAuto-HSCT can improve the clinical efficacy and survival rate of MM patients; ISS stage, CR and VGPR after transplantation are independent prognostic factors for OS and PFS, and induction therapy before transplantation is also an independent prognostic factor for PFS.

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.

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.

Objective To analyze etiology of hospitalized hypertensive patients in the department of hypertension from 1999 to 2008. Methods This retrospective study was performed to analyze the etiology of hospitalized hypertensive patients in department of hypertension and to show the distribution change of hypertension from 1999 to 2008. Results ( 1 ) There were 5867 ( 75. 1% ) patients with essential hypertension and 1942 (24. 9% ) patients with secondary hypertension (SH). (2) The prevalence rate of SH increased significantly during the 10 years (χ2 = 387.621 ,P ＜ 0.001 ) and was higher in 2008 than in 1999 (39. 3% vs. 9. 5% , P ＜ 0. 05 ). The prevalence of obstructive sleep apnea syndrome (OSAS) and primary aldosteronism (PA) in 2008 increased 38.3 and 1.8 times respectively than in 1999 (χ2 =304. 025 ,P ＜0. 001; χ2 =42. 845 ,P ＜0. 001 ) and other SH remained unchanged. ( 3 ) The prevalence of PA complicated with OSAS increased significantly in recent five years ( χ2 = 26.376, P ＜0. 001 ). Incidence of OSAS was 23.9% in PA patients and incidence of PA was 6. 7% in OSAS patients. Conclusions With the insights gained on hypertension mechanism and the development of new diagnostic technology, percent of diagnosed SH increased remarkably in recent years in hospitalized hypertensive patients in our department of hypertension. OSAS and PA are the leading causes of SH.

BACKGROUNDNon-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.

METHODSOne 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.

RESULTSTransmission 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).

CONCLUSIONSThere 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.

Objective To analyze the etiology of 628 patients with refractory hypertension and to observe the disease distribution with respect to gender and different age groups. Methods In this study,clinical data of 628 refractory hypertensives who hospitalized in our hospital from September 1997 to December 2005 were retrospectively analyzed. Results (1) There were 80.1% (503/628) patients with essential hypertension, 18. 9% (119/628) with secondary hypertension (SH) while diagnosis was not clear in 1.0% (6/628) patients. Renovascular hypertension (33.6%) and obstructive sleep apnea syndrome (23.5%) were the major causes of SH. The highest prevalence rate of endocrine hypertension was primary aldosteronism (13.5%). (2) There were significantly more male patients than female patients with essential hypertension, SH, renal hypertension, obstructive sleep apnea syndrome, rimary aldosteronism while the incidence of pheochromocytoma in female was significantly higher than that in male patients (all P < 0.05).The incidence of renovascular hypertension was similar between male and female patients. (3) SH occurred more often in young patients (33.1%) than in aged patients (13.8%, P < 0.05). Conclusion Our data from this patient cohort showed that SH, especially renovascular hypertension and obstructive sleep apnea syndrome are major causes for refractory hypertension in young patients and primary aldosteromsm was the commonest reason of endocrine hypertension in youth and middle-aged patients with refractory hypertension.

OBJECTIVETo establish a quick method to detect drug resistance of Mycoplasma pneumoniae (MP) and study the condition of drug resistance in MP infection.

METHODSMP 23S rRNA target gene in throat swab specimens from 200 patients with suspected MP infection was detected by using nested PCR and DNA sequencing. The result of 23S rRNA gene detection was confirmed by MP isolation and drug susceptibility test in vitro for reliability.

RESULTSOf the 200 clinical specimens, 64 were proved to be positive for MP through MP-IgM antibody, MP specific 16S rRNA nested PCR and MP isolation . The 23S rRNA gene was amplified and the gene sequence was compared with MP reference strain in Genbank, 26 were identical to the reference strain, 38 had a point mutation in 23S rRNA. Among them, 35 had A to G mutation at position 2063, 1 had A to C mutation at position 2063 and 2 had A to G mutation at position 2064, the percentage of drug resistance was 59.4%. The sensitivity of the gene detection method was 10(2) ccu/ml and it was confirmed to be reliable by MP isolation and drug susceptibility test.

CONCLUSIONSThe gene detection method could detect MP drug resistant gene directly from clinical specimen, which has the advantages of high specificity, high sensitivity and quickness. It is of great significance for diagnosis of MP infection because MP isolation is difficult and time-consuming.

OBJECTIVETo explore the role of CD(8)(+)CD(28)(-) T regulatory cells (Tr) in the immunological pathogenesis of acute infection with Epstein-Barr virus in children.

METHODSThe present study enrolled 25 children with infectious mononucleosis (IM) and 25 age-matched healthy children. Flow cytometric analysis was performed to detect the percentage of CD(3)(+), CD(3)(+)CD(4)(+), CD(3)(+)CD(8)(+), CD(8)(+)CD(28)(+) by determining the ratio of positive cells in lymphocytes. Reverse transcriptase-polymerase chain reaction (RT-PCR) and real-time PCR were used to analyze IL-6, IL-10, IFN-gamma expression in CD(8)(+)CD(28)(-) Tr cells and ILT-3, ILT-4 expression in monocytes/macrophages.

RESULTSThe proportions of CD(8)(+)CD(28)(-)T cells in children with acute-phase IM was significantly higher than those in the controls (P < 0.01). The expression level of IL-6, IL-10, IFN-gamma, ILT-3, ILT-4 mRNA significantly increased compared to those of the controls (P < 0.01).

CONCLUSIONThe CD(28) expressed on CD(8)(+) T cells in vivo is gradually lost with age and CD(8)(+)CD(28)(-) cells increase up 50% to adult. EBV can directly infect B cells, trigger CD(8)(+) CTL response and destroy the target cells to cause serious immunopathological lesion. Therefore we speculate that the expansion of CD(8)(+)CD(28)(-) Tr cells in children with IM may be an adaptive immune response to avoid serious inflammation and autoimmune reactions.
