OBJECTIVE: To compare the effects of direct fluorescence in situ hybridization (D-FISH) detection without sorting and CD138 immunomagnetic bead sorting technology combined with FISH (MACS-FISH) on cytogenetic analysis of patients with multiple myeloma (MM). METHODS: FISH test results of 229 patients with initial MM were retrospectively analyzed. The patients were divided into two groups, 140 patients were tested with D-FISH and 89 patients with MACS-FISH. The combination probe was designed as P53, D13S319, RB1, 1q21, and IgH. Cytogenetic detection results were compared between the two groups. RESULTS: The total detection rate of cytogenetic abnormalities in D-FISH group was 52.9%, and that in MACS-FISH group was 79.8%. There was a significant difference in the cytogenetic abnormality rate between the two groups (P=0.020). The abnormal genes with the highest detection rate in the two groups were 1q21 and IgH, respectively, while the lowest was P53. There was no significant difference in the percentage of P53 positive cells (positive rate) between the two groups, while D13S319, RB1, 1q21, and IgH showed significant difference in positive cell rate (P=0.0002, P<0.0001, P=0.0033, P=0.0032). There was no significant correlation between the proportion of plasma cells (PC) detected by bone marrow morphology and cytogenetic abnormality rate in the D-FISH group, while there was a correlation between the proportion of PC detected by flow cytometry and cytogenetic abnormality rate (r=0.364). The PC proportion detected by bone marrow morphology and flow cytometry in the MACS-FISH group had no correlation with the cytogenetic abnormality rate and positive cell rate of the 5 genes mentioned above. Additionally, the PC proportion detected by bone marrow morphology and flow cytometry showed significant difference (P<0.0001). CONCLUSION CD138 immunomagnetic bead sorting combined with FISH technology can significantly improve the abnormality detection rate of MM cytogenetics.

Background:Transcranial alternating current stimulation (tACS) offers a new approach for adult patients with major depressive disorder (MDD).The study is to evaluate the efficacy and safety of tACS treating MDD.Methods:This is an 8-week,double-blind,randomized,placebo-controlled study.Ninety-two drug-naive patients with MDD aged 18 to 65 years will receive 20 daily 40-min,77.5-Hz,15-mA sessions of active or sham tACS targeting the forehead and both mastoid areas on weekdays for 4 consecutive weeks (week 4),following a 4-week observation period (week 8).The primary outcome is the remission rate defined as the 17-item Hamilton depression rating scale (HDRS-17) score ≤7 at week 8.Secondary outcomes are the rates of response at weeks 4 and 8 and rate of remission at week 4 based on HDRS-17,the proportion of participants having improvement in the clinical global impression-improvement,the change in HDRS-17 score (range,0-52,with higher scores indicating more depression) over the study,and variations of brain imaging and neurocognition from baseline to week 4.Safety will be assessed by vital signs at weeks 4 and 8,and adverse events will be collected during the entire study.Discussion:The tACS applied in this trial may have treatment effects on MDD with minimal side effects.

The study aims at investigating the grade standard and the quality characteristic of Pinelliae Rhizoma for commodity specification, which provides the reference for its grade standard formulation. 42 Pinelliae Rhizoma simples were collected from 5 medicinal materials markets and 2 producing areas. Based on the previous herbalogical study and market investigation, we combined with the data analysis to select the grading indicators using SPSS software for descriptive statistical analysis, analysis of variance, K-cluster analysis and correlation analysis. According to the actual production condition, we developed the grading standards of Pinelliae Rhizoma. Moreover, we compared the internal indicators(water, total ash, leachate and guanosine) of Pinelliae Rhizoma at various grade levels, and analyzed the correlation between appearance traits and internal indicators. The herbalogical study and market research found that the Pinelliae Rhizoma was better in large, solid and white. The results from descriptive and variance analysis showed that the appearance of Pinelliae Rhizoma was significantly different in weight per grain and grain number of 500 g. Referring to the 2015 Chinese Pharmacopoeia and the production practice, we use the length, weight per grain and grain number of 500 g as the classification index of Pinelliae Rhizoma. The results from correlation analysis showed that there was no significant correlation between the appearance of Pinelliae Rhizoma and the intrinsic quality index. In addition, we found there was no significant difference in the content of the intrinsic index except for the total ash and the extract. The current study established the classification index of the product specification and grade standard of Pinelliae Rhizoma with length, weight per grain and grain number of 500 g as the index, which can provide the basis for the classification of the product specification and grade of Pinelliae Rhizoma market.

OBJECTIVE: To described the clinical and laboratory features and outcome of 67 macrophage activation syndrome (MAS). METHODS: A total of 67 MAS patients from three centers from January 2007 to December 2017 were enrolled. Clinical and laboratory features, and response to therapy were analyzed. Predictive factors for remission and survival were explored. RESULTS: We identified a mean age of (36.1±16.3) years at diagnosis of MAS and a median connective tissue disease (CTD) duration of 8 months prior to MAS development. Among 67 MAS patients identified, underlying diseases included adult-onset Still's disease (AOSD) in 56.7% and systemic lupus erythematosus (SLE) in 30.0%. Fever and splenomegaly were found in 100.0% and 82.1% of the patients, respectively. Ferritinemia and elevation of serum soluble interleukin-2 receptor was seen in 100.0% and 93.2% of the patients. Serum levels of alanine aminotransferase, D-dimer, ferritin and C reactive protein were significantly higher in MAS associated with the AOSD patients than in MAS associated with the SLE patients. A significant decrease of erythrocyte sedimentation rate was found in MAS associated with AOSD, as compared with MAS associated with SLE. The most commonly used therapy was corticosteroids, which were initially administered in 100.0% of the patients. Intravenous immunoglobulin (IVIG) was administered in 91.0%, cyclosporine A in 64.2%, and etoposide in 46.3% of the patients, respectively. The induction therapy yielded a complete remission (CR) at the end of week 8 in 47.8% of the MAS patients. The overall mortality rate at the end of week 16 was 22.4%. The median serum levels of gamma-glutamyltransferase, alkaline phosphatase, total bilirubin and direct bilirubin were significantly lower in the patients who achieved complete remission at the end of week 8 than in those who did not, and splenomegaly was significantly less frequent (71.9% vs.91.4%, P=0.037). Both the mean age at diagnosis of MAS and the mean age at diagnosis of underlying CTD of the deceased patients were elder than those of the survived population (P=0.014 and P=0.017, respectively). The platelet count was significantly less in the deceased population as compared with the living population (P=0.018). No addition of cyclosporine A (P=0.004) was identified as risk factors associated with death in Logistic regression analysis. CONCLUSION MAS secondary to connective tissue disease is most common with AOSD and SLE. In terms of laboratory findings, there were considerable differences between the patients with underlying SLE and those with AOSD. Advanced age and low platelet counts are significant predictive factors for death, while treatment with cyclosporine may reduce the risk.

Objective:To investigate the differential expression and gene functions of up-regulated genes in rats with spinal cord injury. Methods:Female Sprague-Dawley rats' model of spinal cord injury was established with the modified Allen's method. Gene chip technology was used to detect the variation of differentially expressed genes in the spinal cord after spinal cord injury in rats. The differences in genes, functional localization and pathways were analyzed with gene ontology and Kyoto Encyclopedia of Genes and Genomes pathway database. Results:The results of total RNA quality in spinal cord segment were qualified. Gene chip results showed that there were 1874 differentially up-regulated genes and 2348 differentially down-regulated genes. Bioinformatics was used to analyze differentially up-regulated genes in terms of biological processes, cellular components, and molecular functions. The differentially up-regulated genes were involving apoptosis, immune response, inflammation, etc., pathway analysis mainly showed the differentially up-regulated genes involved phosphoinositide 3-kinase protein kinase B signaling pathway and Toll-like receptor signaling pathways. Conclusion:Differentially up-regulated genes may be involved in secondary reactions following spinal cord injury, such as inflammation, immune response and hypoxia, and then further affect motor function and sensory function.

OBJECTIVE: To investigate the changes of bone mineral density (BMD) and serum bone turnover factor in newly diagnosed systemic lupus erythematous (SLE) patients. METHODS: Eighty newly diagnosed SLE patients and 80 age and gender matched healthy controls were enrolled. None of the SLE patients had ever received glucocorticoid, immunosuppressive agents or vitamin D. BMD was measured at radius,lumbar spine and hip by dual X ray absorptiometry (DXA). Bone turnover markers including serum levels of tartrate-resistant acid phosphatase 5b (TRAP5b),bone alkaline phosphatase (BAP) and 25-hydroxy vitamin D3 (25-OH-VD3) were measured by enzyme-linked immunosorbent assay (ELISA). Logistic regression was employed to analyze the risk factors associated with decreased BMD. RESULTS: Mean age of the SLE patients was (32.8±12.4) years, and 85% were female, none of whom were post-menopausal. BMD was significantly reduced in all the measured sites, compared with the healthy controls. Sixteen (20%) of the patients were osteopenic in at least one site measured locations. The serum levels of 25-OH-VD3 were markedly reduced in the newly diagnosed SLE patients than those of the normal controls [(46.1+12.3) nmol/L vs. (25.4+11.2) nmol/L, P<0.001)]. The serum levels of 25-OH-VD3 in the SLE patients with nephritis were much lower than those without nephritis (P=0.04). A significant negative correlation was demonstrated between the serum concentration of 25-OH-VD3 and the disease activity scores as measured by SLE disease activity index (SLEDAI) (r=-0.3,P=0.001). The serum TRAP5b concentration was positively correlated with SLEDAI (r=0.435,P=0.003). Age (P=0.058) and SLEDAI (P=0.085) were probably associated with decreased BMD in Logistic regression analysis. CONCLUSION The study showed reduced BMD in untreated SLE patients. The role of chronic inflammation was of probable importance in bone metabolism.
