OBJECTIVETo explore the active ingredients in the Chinese yellow wine could inhibit the proliferation and migration of rat vascular smooth muscle cells induced by homocysteine (Hcy).

METHODSThe primary culture and identification of rat vascular smooth muscle cells (VSMCs) was conducted, and the VSMCs in passage 4-7 were used in the following experiments. The VSMCs were divided into 7 groups: control, Hcy (1 mmol/L), Hcy + oligosaccharide, Hcy + polypeptides, Hcy + polyphenols, Hcy + alcohol, Hcy + Chinese yellow wine and were given the corresponding treatment. The proliferation of VSMCs was determined by MTT. Transwell chambers and would healing were employed to test the migratory ability of VSMCs. Wester blot and gelatin zymography were used to investigate the expressions and activities of metal matrix proteinase 2/9 (MMP-2/9) and tissue inhibitor of metalloproteinase 2 (TIMP-2) in VSMCs of each group.

RESULTSCompared with control group, the proliferation, migration and the expression and activity of MMP-2/9 of VSMCs were significantly increased in the VSMCs of Hcy group (P < 0.01). Compared with Hcy group, the proliferation, migration and the expression and activity of MMP-2/9 of VSMCs were significantly decreases in the VSMCs of polypeptides group, polyphenols group and Chinese yellow wine group. However, the expression of TIMP-2 among each group had no significant difference.

CONCLUSIONPolypeptides and polyphenols in the Chinese yellow wine could inhibit the proliferation and migration of VSMCs induced by Hcy.

This study was purposed to investigate the relationship between the catalysis of Bence Jones protein (BJP) in urine of patients with multiple myeloma(MM) and toxicity on the renal proximal tubular cells in vitro, and to explore the potential mechanism for the toxicity of BJP to renal impairment in patients with MM. The Michaelis-Menten constant (K(m)) and catalytic constant (k(cat)) of the amidase activity of BJP was calculated by Hanes equation. The LLC-PK1 cells were cultured with different concentration of BJP for 24 h, then proliferation of the cells were determined by MTT method and apoptosis were determined by flow cytometry. The results showed that the BJP from the MM patients with renal impairment significantly inhibited cell proliferation, as compared with that from MM patients without renal impairment. The BJP with higher k(cat) had higher toxicity to LLC-PK1 cells. BJP could induce apoptosis and necrosis of LLC-PK1 cells when reached a certain concentration and this effect enhanced with increase of BJP concentration. It is concluded that the catalysis of BJP and its toxicity to renal tubular epithelial cells has a positive correlation, and toxic effect of BJP on renal tubular epithelial cells results from inhibiting proliferation and inducing apoptosis and necrosis of the cells, which may be one of renal impairment mechanisms in MM patients.

This study was purposed to evaluate the clinical significance of low molecular weight urinary proteins for diagnosis of early renal damage in patients with multiple myeloma (MM). Medical records of 278 patients with MM in Nanjing School of Clinical Medicine from January 2004 to May 2012 were analyzed retrospectively. These patients were divided into 3 groups: glomerular damage group (n = 143), tubular damage group (n = 114) and normal group (n = 21). The clinical and laboratorial data were compared among them. The correlations of urinary retinol-binding protein (RBP) or urinary N-acetyl-β-D-amino-glucosaminidase (NAG) with blood urea nitrogen (BUN), Scr, blood cystatin-C (Cys-C), clearance of creatinine (Ccr), 24 h protein uria and 24 h urine light chains were further analyzed, and the correlation of renal tubulointerstitial lesion scores with low molecular weight urinary proteins in 61 patients were also analyzed. The area under curve (ROC curve) was used to evaluate and compare the discrimination of urinary RBP and urinary NAG. The results showed that glomerular damage group had higher urinary RBP than tubular damage group. However, glomerular damage group had lower urinary NAG than tubular damage group. The two groups had higher urinary RBP and urinary NAG than that in normal group. Urinary RBP related positively to the level of Scr, BUN, Cys-C, 24 h proteinurias and related negatively to the level of Ccr. Urinary NAG related positively to the level of 24 h proteinurias, Ccr and related negatively to the level of Cys-C. Renal tubulointerstitial lesions were significantly correlated with urinary RBP, but weakly correlated with urinary NAG. It is concluded that urinary RBP significantly correlates with renal tubular damage. Compared with urinary NAG, urinary RBP can better assess the extent of renal damage, and has higher specificity.

OBJECTIVETo evaluate the efficacy and feasibility of bortezomib plus dexamethasone (BD) in patients with primary systemic (AL) amyloidosis.

METHODSEleven AL amyloidosis patients, including four relapsed or progressed after previous therapies and 7 newly diagnosed were treated with BD. Ten patients had two or more organs involved. Precursor protein analysis showed that 1 was κ light chain, 9 λ light chain; 5 patients with positive immunofixation including 1 IgG κ, 3 IgG λ and 1 IgA λ. BD was administered according to standard two-week schedule.

RESULTSEight patients were evaluable, the median number of treatment cycles was 3 (range 1 - 6). Median follow-up duration was 6 months. At least one affected organ response was observed in six patients and median time to organ response was 2 months. Three patients progressed and two of them died. Toxicities were mainly diarrhea, thrombocytopenia, peripheral neuropathy, fatigue and herpes zoster, and 7 evaluable patients who had toxicities were adjusted dosage and 2 of them interrupted therapy. Epilepsia, paralytic ileus, acute cardiac dysfunction, and postural hypotention were occurred in 3 inevaluble patients.

CONCLUSIONBortezomib plus dexamethasone is effective in AL amyloidosis. Adverse events are common, and in some patients are severe.

This study was aimed to investigate the clinical characteristics and treatment of patients with autoimmune disease combined with non-Hodgkin lymphoma (NHL). The clinical characteristics and pathologic patterns of 6 patients with NHL who concurrently suffered from autoimmune diseases were analysed retrospectively from aspects of clinical course, pathologic features, and therapy. Treatment outcomes for autoimmune diseases and NHL were observed. The results showed that 6 patients included 4 females and 2 males, range in age from 28 to 65 years with a median age of 56 years. The autoimmune diseases are Sjogren's syndrome (SS, 2 cases), rheumatoid arthritis (RA, 2 cases), ulcerative colitis (UC, 1 case) and Crohn's disease (CD, 1 case). The NHL diseases located not only in the lymph node (n = 3) but also in extranodal sites (n = 3). Histologically, 3 cases were diffuse large B cell lymphoma (DLBCL), 2 cases were extranodal nasal NK/T lymphoma (ENKL) and 1 case was peripheral T cell lymphoma, not otherwise specified. Based on CD10, Bcl-6 and MUM1 expression patterns, all 3 DLBCL were classified as non-GC subtype. EBER positive tumor cells were detected in 2 case of ENKL. 5 patients achieved a complete remission (83%) and 1 patient was primary drug-resistant after CHOP chemotherapy or involved radiotherapy. Median survival from the time of lymphoma diagnosis was 3 years. 1 patient showed clinical improvement of the SS symptoms, 2 patients (CD and UC) showed stable state of disease and 2 patients with RA and 1 patient with SS needed continuing treatment for their autoimmune diseases after chemotherapy for NHL. It is concluded that the development of NHL is one of the most serious complications in patients with autoimmune diseases. There is an increased frequency of non-GC subtype DLBCL. CHOP combined with or without radiotherapy proves to be effective for autoimmune disease patients with aggressive NHL but ineffective for concurrent autoimmune diseases.

The objective of this study was to explore the clinical significance of measuring serum free light chains (sFLC) and to compare with serum total light chains (free and binded) in multiple myeloma (MM). sFLC in 20 newly diagnosed MM patients and 20 cases of healthy people as control were measured by immuno-nephelometric assays; the serum light chains and kappa/lambda ratio were measured in all patients, while immunofixation electrophoresis (IFE) tests were carried out at the same time in 18 out of 20 patients. The results showed that the abnormality of serum free light chains and kappa/lambda ratio were found in all of the 20 newly diagnosed MM patients (p < 0.01). The measurement of sFLC showed higher sensitivity than the total serum chains (p < 0.01). It is concluded that the method testing sFLC by immuno-nephelometric assay combined with kappa/lambda ratio is valuable for MM diagnosis, and the measurement of sFLC can be used as one of indicators for MM diagnosis.

OBJECTIVETo identify the factors that affect the safety and efficacy of peroral endoscopic myotomy (POEM) for treatment of achalasia.

METHODSData of consecutive patients undergoing POEM for confirmed achalasia between December, 2010 and December, 2015 were collected, including the procedure time, approach of tunnel entry incision, approach of myotomy, complications and follow-up data.

RESULTSAmong the total of 439 patients enrolled, the overall complication rate was 28.7% (126/439). Treatment success (Eckardt score≤3) was achieved in 94.5% of 364 patients followed up for a median of 6 months (1-48 months), and the mean score was reduced significantly from 6.7∓1.5 before treatment to 1.2∓1.1 after the treatment (P<0.05). Logistic regression revealed that the year when POEM was performed and the approach of entry incision were two significant factors contributing to complications: with the year 2015 as the reference, the odds ratio (OR) was 9.454 (95% CI: 2.499-35.76) for the years before 2011, 2.177 (95% CI: 0.794-5.974) for 2012, 3.975 (95% CI: 1.904-8.298) for 2013, and 1.079 (95% CI: 0.601-1.940) for 2014; with the longitudinal entry incision as the reference, the OR was 0.369 (95% CI: 0.165-0.824) for inverted T entry incision and 0.456 (95% CI: 0.242-0.859) for transverse entry incision. The approach of myotomy was the significantly associated with symptomatic relapse: with full-thickness myotomy combined with indwelling an anti-reflux belt as the reference, the OR was 0.363 (95% CI: 0.059-2.250) for gradual full-thickness myotomy, 2.137 (95% CI: 0.440-10.378) for circular muscle myotomy, and 4.385 (95% CI: 0.820-23.438) for circular muscle myotomy in combination with balloon shaping; the recurrence rate was 0 with a full-thickness myotomy.

CONCLUSIONThe complication rates of POEM appears to decrease over time, and an inverted T entry incision is the best choice for controlling the complications. Gradual full-thickness myotomy is an excellent approach for treatment of achalasia in terms of the relapse rate, procedure time and the incidence of reflux esophagitis.
