OBJECTIVE: To detect the relationship between CTGF in the bone marrow of MM patients and osteolytic lesion of myeloma, moreover, to investigate the clinical significance of CTGF in MM. METHODS: Fifity-four MM patients treated in our hospital from March 2019 to April 2020 were enrolled, and 28 healthy volunteers were selected as the control group. The plasma in bone marrow of the patients was collected, and the ELISA was used to detect the level of CTGF in bone marrow plasma and the relationship between its and clinical characteristics were statistically analyzed. RESULTS: The CTGF level of MM patients was significantly higher than those in the healthy control group (P<0.001); the CTGF level in male patients was higher than that in female patients (P=0.007); the CTGF level in MM patients with osteolytic lesions was significantly higher than patients without osteolytic lesions and controls (P=0.007, P=0.001). The CTGF level in MM patients was positively correlated with the number of bone lesions (P<0.001, r=0.52). CTGF levels in patients with ≥3 bone lesions were significantly higher than those with <3 bone lesions and without bone lesions (P=0.014, P=0.002). ROC curve result showed that CTGF expression level shows a significant diagnostic value for MM bone disease (P<0.001). CONCLUSION The abnormally high expression of CTGF level in MM patients is related to the degree of myelomas osteolytic lesions and can reflect the progress of MM.

BACKGROUND: Irritable bowel syndrome (IBS) is reported associated with the alteration of gut microbial composition termed as dysbiosis. However, the pathogenic mechanism of IBS remains unclear, while the studies of Chinese individuals are scarce. This study aimed to understand the concept of dysbiosis among patients with Chinese diarrhea-predominant IBS (IBS-D), as a degree of variance between the gut microbiomes of IBS-D population and that of a healthy population. METHODS: The patients with IBS-D were recruited (assessed according to the Rome III criteria, by IBS symptom severity score) from the Outpatient Department of Gastroenterology of Peking University Third Hospital, and volunteers as healthy controls (HCs) were enrolled, during 2013. The 16S rRNA sequences were extracted from fecal samples. Ribosomal database project resources, basic local alignment search tool, and SparCC software were used to obtain the phylotype composition of samples and the internal interactions of the microbial community. Herein, the non-parametric test, Wilcoxon rank-sum test was carried out to find the statistical significance between HC and IBS-D groups. All the P values were adjusted to q values to decrease the error rate. RESULTS: The study characterized the gut microbiomes of Chinese patients with IBS-D, and demonstrated that the dysbiosis could be characterized as directed alteration of the microbiome composition leading to greater disparity between relative abundance of two phyla, Bacteroidetes (Z = 4.77, q = 1.59 × 10) and Firmicutes (Z = -3.87, q = 5.83 × 10). Moreover, it indicated that the IBS symptom features were associated with the dysbiosis of whole gut microbiome, instead of one or several certain genera even they were dominating. Two genera, Bacteroides and Lachnospiracea incertae sedis, were identified as the core genera, meanwhile, the non-core genera contribute to a larger pan-microbiome of the gut microbiome. Furthermore, the dysbiosis in patients with IBS-D was associated with a reduction of network complexity of the interacted microbial community (HC vs. IBS-D: 639 vs. 154). The disordered metabolic functions of patients with IBS-D were identified as the potential influence of gut microbiome on the host (significant difference with q < 0.01 between HC and IBS-D). CONCLUSIONS This study supported the view of the potential influence of gut microbiome on the symptom of Chinese patients with IBS-D, and further characterized dysbiosis in Chinese patients with IBS-D, thus provided more pathological evidences for IBS-D with the further understanding of dysbiosis.

Background: Hyperphosphatemia is a risk factor associated with mortality in patients on maintenance hemodialysis. Gut absorption of phosphate is the major source. Recent studies indicated that the intestinal flora of uremic patients changed a lot compared with the healthy population, and phosphorus is an essential element of bacterial survival and reproduction. The purpose of this study was to explore the role of intestinal microbiota in phosphorus metabolism. Methods: A prospective self-control study was performed from October 2015 to January 2016. Microbial DNA was isolated from the stools of 20 healthy controls and 21 maintenance hemodialysis patients. Fourteen out of the 21 patients were treated with lanthanum carbonate for 12 weeks. Thus, stools were also collected before and after the treatment. The bacterial composition was analyzed based on 16S ribosomal RNA pyrosequencing. Bioinformatics tools, including sequence alignment, abundance profiling, and taxonomic diversity, were used in microbiome data analyses. Correlations between genera and the serum phosphorus were detected with Pearson's correlation. For visualization of the internal interactions and further measurement of the microbial community, SparCC was used to calculate the Spearman correlation coefficient with the corresponding P value between each two genera. Results: Thirteen genera closely correlated with serum phosphorus and the correlation coefficient was above 0.4 (P < 0.05). We also found that 58 bacterial operational taxonomic units (OTUs) were significantly different and more decreased OTUs were identified and seven genera (P < 0.05) were obviously reduced after using the phosphate binder. Meanwhile, the microbial richness and diversity presented downward trend in hemodialysis patients compared with healthy controls and more downward trend after phosphorus reduction. The co-occurrence network of genera revealed that the network complexity of hemodialysis patients was significantly higher than that of controls, whereas treatment with lanthanum carbonate reduced the network complexity. Conclusions Gut flora related to phosphorus metabolism in hemodialysis patients, and improving intestinal microbiota may regulate the absorption of phosphate in the intestine. The use of phosphate binder lanthanum carbonate leads to a tendency of decreasing microbial diversity and lower network complexity.

OBJECTIVETo explore the efficacy and prognosis of first-line autologous hematopoietic stem cell transplantation (ASCT) for newly diagnosed patients with multiple myeloma(MM).

METHODSFrom January 2005 to December 31, 2012, 60 patients with MM were enrolled. All patients received thalidomide or/and bortezomib-based induction therapy, then received high-dose melphalan (200 mg/m²) and autologous stem cell support to get a ≥ partial response (PR), and followed by thalidomide-dexamethasone (TD) ±bortezomib as consolidation or maintenance treatment. With the follow up to December 31, 2012, the overall survival (OS), progression free survival (PFS) and the prognostic factors, including ISS stage, response and fluorescent in situ hybridization (FISH) data of cytogenetics were analyzed.

RESULTSWith a median follow up of 36.8 (12.0-102.5) months, the median OS and PFS estimate were not reached and 86.5 months, respectively. After transplantation, all (100%) patients received very good partial response (VGPR), and 34 (56.7%) patients achieved complete response (CR) after consolidation or maintenance treatment. The patients that achieved CR resulted in long term PFS (P=0.030), with no difference in OS (P=0.942). The univariate analysis showed that the abnormalities, including 13q14 deletion, 1q21 gain, IgH location and p53 deletion had the prognostic impacts. If the t(4;14) or p53 deletion was excluded, there would be no correlation between 13q14 deletion or 1q21 gain with PFS and OS. The patients with p53 deletion had a worst survival.

CONCLUSIONThere has been significant improvement in the outcome for young MM patients by using ASCT and novel drugs. Cytogenetic abnormalities and response to therapy are the main factors affecting the survival of patients.

BACKGROUNDBivalirudin was widely used as an anticoagulant during coronary interventional procedure in western countries. However, it was not available in China before this clinical trial was designed. This randomized, single-blind and multicenter clinical trial aimed to evaluate the efficacy and the safety of domestic bivalirudin during percutaneous coronary intervention (PCI).

METHODSA randomized, single-blind, multicenter trial was designed. Elective PCI candidates in five centers were randomized into a bivalirudin group and a heparin group, which were treated with domestic bivalirudin and non-fractional heparin during the PCI procedure. The efficacy was evaluated by comparing the activated coagulation time (ACT), the procedural success rate (residual stenosis < 20% in target lesions without any coronary artery related adverse events within 24 hours after PCI), and the survival rate without major adverse cardiac events at 30 days after PCI between the two groups. Safety was evaluated by the major/minor bleeding rate.

RESULTSA total of 218 elective PCI patients were randomized into a bivalirudin group (n = 110) and heparin group (n = 108). Except for two patients needing additional dosing in the heparin group, the ACT values of all other patients in both groups were longer than 225 seconds at 5 minutes after the first intravenous bolus. Procedural success rates were respectively 100.0% and 98.2% in the bivalirudin group and heparin group (P > 0.05). Survival rates without major adverse cardiac events at 30 days after PCI were 100.0% in the bivalirudin group and 98.2% in the heparin group (P > 0.05). Mild bleeding rates were 0.9% and 6.9% (P < 0.05) at 24 hours, and 1.9% and 8.8% (P < 0.05) at 30 days after PCI in the bivalirudin group and heparin group respectively. There was one severe gastrointestinal bleeding case in the heparin group.

CONCLUSIONSDomestic bivalirudin is an effective and safe anticoagulant during elective PCI procedures. The efficacy is not inferior to heparin, but the safety is superior to heparin.

OBJECTIVETo study the prevalence of hepatitis B infections and carrier status among general population in Chaoyang district, Beijing in 2010.

METHODSFrom May to December 2010, 14 491 subjects over 12 months old were selected by multistage random cluster sampling method from residents in Chaoyang district, Beijing. Five millilitre venous blood specimens were collected from these subjects to test hepatitis B virus antigens and antibodies. Status of hepatitis B infections were analyzed in different age, sex and registered permanent residence groups.

RESULTSThe overall positive rate of surface antigen (HBsAg) was 2.66% (383/14 410). The lowest rate of 0.56% (9/1603) was found in the 1 to 14 years old group and the 35 to 44 years old group had the highest rate of 4.27% (92/2154). The rate in subjects younger than 24 years old was 1.03% (31/2986). The overall positive rate of surface antibody (anti-HBs) was 40.21% (5798/14 421). The highest positive rate of anti-HBs (80.59%, 407/505) was found in the 1 to 4 years old group. The overall positive rate of core antibody (anti-HBc) was 30.26% (4364/14 424). The overall hepatitis B virus infection rate was 30.32% (4364/14 393). For male and female groups, the positive rates of HBsAg were 2.93% (179/6108) and 2.44% (202/8287) respectively (χ² = 3.32, P > 0.05); anti-HBs were 41.93% (2563/6113) and 38.96% (3231/8293) respectively (χ² = 12.88, P < 0.01); and anti-HBc were 31.39% (1919/6114) and 29.39% (2438/8295) respectively (χ² = 6.65, P = 0.01). For local residents group and mobile population group, the positive rates of HBsAg were 2.46% (283/11 510) and 3.60% (98/2719) respectively (χ² = 11.08, P < 0.01); anti-HBs were 37.11% (4293/11 568) and 53.07% (1445/2723) respectively (χ² = 233.51, P < 0.01); and anti-HBc were 30.83% (3567/11 570), and 28.41% (774/2724) respectively (χ² = 6.08, P < 0.05).

CONCLUSIONThe positive rate of HBsAg in population younger than 24 years old has reached a relatively low level. The mobile population has significantly higher positive rate of HBsAg than local residents, indicating the need for enhancing prevention and control measures for hepatitis B for the mobile population and local residents over 25 years old.

AIMTo explore the effect of cerebellar fastigial nuclei (FN)on lymphocyte function and the pathway mediating the effect.

METHODSKainic acid (KA) was microinjected into bilateral FN of rats to destroy neuronal bodies in the FN. On the eighth day after the surgery, lymphocyte percentage in the peripheral blood and level of sheep red blood cell(SRBC)-specific IgM antibody in the serum were measured by using blood corpuscle counter and enzyme-linked immunosorbent assay (ELISA), respectively.A technology of electrolytic lesion was used to destroy the projections of cerebellar FN neurons to hypothalamus in decussation of superior cerebellar peduncle(xscp).

RESULTSOn the eighth day after the microinjection of KA into the bilateral FN of rats, the Nissl-stained neuronal bodies in the FN disappeared and glia could proliferated within the damaged FN. In the nuclei close to FN, the interposed nuclei and the dentate nuclei, Nissl-stained neurons still could be seen. On the control cerebellar sections, in which FN was infused with saline, we could see the normal Nissl-stained neurons in the FN and the other two nuclei.On day 8 following the effective FN lesions, both the lymphocyte percentage in the peripheral blood and the level of anti-SRBC IgM antibody in the serum were significantly increased in comparison with those of control rats infused with saline in the FN. On the eighth day after electrolytic lesion of the fibres in xscp, the FN-hypothalamic projections were damaged and there were no visible BDA-positive endings in hypothalamus. Meanwhile, both the lymphocyte percentage in the peripheral blood and the level of anti-SRBC IgM antibody in the serum were remarkably enhanced relative to those of control rats with sham lesion of xscp.

CONCLUSIONThe electrolytic lesion of the FN-hypothalamic projections in xscp causes an enhancement of lymphocyte function similar to that of KA lesions of neuronal soma in the FN. These findings suggest that the cerebellohypothalamic projections participate in mediating the modulation of lymphocyte function by the cerebellum.
