Objective: To investigate the clinical features and long-term prognostic factors of diabetic patients with low or intermediate complexity coronary artery disease (CAD) post percutaneous coronary intervention (PCI). Methods: This was a prospective, single-centre observational study. Consecutive diabetic patients with SYNTAX score (SS)≤32 undergoing PCI between January and December 2013 in Fuwai hospital were included in this analysis. The patients were divided into two groups based on SS, namely SS≤22 group and SS 23-32 group. Multivariate Cox regression analysis was performed to identify independent factors related to poor 5-year prognosis. The primary outcomes were cardiac death and recurrent myocardial infarction, the secondary outcomes were all cause death and revascularization. Results: Of the 3 899 patients included in the study, 2 888 were men (74.1%); mean age was 59.4±9.8 years. There were 3 450 patients in the SS≤22 group and 449 patients in the SS 23-32 group. Compared with SS≤22 group, the incidence of revascularization was higher in SS 23-32 group (18.9% (85/449) vs. 15.2% (524/3450), log-rank P=0.019). There was no significant difference in all-cause death, cardiac death and recurrent myocardial infarction between the two groups (log-rank P>0.05). Multivariate Cox regression analysis showed that age (HR=1.05, 95%CI 1.02-1.08, P<0.001), chronic obstructive pulmonary disease (HR=3.12, 95%CI 1.37-7.07, P=0.007) and creatinine clearance rate (CCr)<60 ml/min (HR=3.67, 95%CI 2.05-6.58, P<0.001) were independent risk factors for 5-year cardiac death, while left ventricular ejection fraction (HR=0.94, 95%CI 0.91-0.96, P<0.001) was a protective factor. Previous PCI (HR=2.04, 95%CI 1.38-3.00, P<0.001), blood glucose level≥11.1 mmol/L on admission (HR=2.49, 95%CI 1.32-4.70, P=0.005) and CCr<60 ml/min (HR=1.85, 95%CI 1.14-2.99, P=0.012) were independent risk factors for 5-year recurrent myocardial infarction. The SS of 23-32 was independently associated with risk of revascularization (HR=1.54, 95%CI 1.09-2.16, P=0.014), after adjusting for residual SS. Residual SS was not a risk factor for 5-year prognosis. Conclusions: In diabetic patients with low-or intermediate complexity CAD, SS 23-32 is associated with increased risk of 5-year revascularization; the clinical characteristics of the patients are associated with the long-term mortality and recurrent myocardial infarction, but not related to revascularization.

In order to evaluate the composition and distribution characteristics of inorganic elements in Laminaria japonica, this study employed inductively coupled plasma mass spectrometry(ICP-MS) to detect the inorganic elements and used high performance liquid chromatography tandem ICP-MS(HPLC-ICP-MS) to determine the content of different arsenic species in L. japonica from diffe-rent origins. Micro X-ray fluorescence(Micro-XRF) was used to determine micro-area distribution of inorganic elements in L. japonica. The results showed that the average content of Mn, Fe, Sr, and Al was high, and that of As and Cr exceeded the limits of the national food safety standard. According to the results of HPLC-ICP-MS, arsenobetaine(AsB) was the main species of As contained in L. japonica. The more toxic inorganic arsenic accounts for a small proportion, whereas its content was 1-4 times of the limit in the national food safety standard. The results of Micro-XRF showed that As, Pb, Fe, Cu, Mn, and Ni were mainly distributed on the surface of L. japonica. Among them, As and Pb had a clear tendency to diffuse from the surface to the inside. The results of the study can provide a basis for the processing as well as the medicinal and edible safety evaluation of L. japonica.

OBJECTIVE: To observe the efficacy of acupuncture on symptom burden in patients with gastric cancer during adjuvant chemotherapy after gastrectomy. METHODS: A total of 58 patients were randomized into a high-dose acupuncture group (19 cases, 5 cases dropped off), a low-dose acupuncture group (20 cases, 6 cases dropped off) and a control group (19 cases, 2 cases dropped off). Conventional chemotherapy and antiemetic treatment were adopted in the control group. On the basis of the treatment in the control group, acupuncture was applied 7 times each chemotherapy cycle for totally 21 times in the high-dose acupuncture group, and 3 times each chemotherapy cycle for totally 9 times in the low-dose acupuncture group. Baihui (GV 20), Zusanli (ST 36), Neiguan (PC 6), etc. were selected in the two acupuncture groups, as well as back-shu points selected by the meridian heat sensing technique. Electroacupuncture was connected to ipsilateral Zusanli (ST 36) and Neiguan (PC 6), with continuous wave, 2 Hz in frequency for 20 min. The Edmonton symptom assessment system (ESAS) score was observed on day 1-7, 14, and 21 of each cycle of chemotherapy respectively in the 3 groups. RESULTS: The symptom burden was worst within 7 days of each cycle of chemotherapy in the 3 groups. After the 3rd chemotherapy cycle, the total score of ESAS in the low-dose acupuncture group was lower than the control group (P<0.05), the total score and the scores of feeling of non-well being, pain and shortness of breath of ESAS in the acupuncture group (the high-dose acupuncture group combined with the low-dose acupuncture group) were lower than the control group (P<0.05). CONCLUSION Acupuncture shows promising effect in controlling symptom burden during adjuvant chemotherapy in gastric cancer patients after gastrectomy.

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.

The proportion of CD4⁺ T lymphocytes, CD8⁺ T lymphocytes, Treg cells and plasma cells in the specimens and the expressions of PD-1, PD-L1 and CTLA-4 were detected by multi-parameter flow cytometry. RESULTS: There was no significant difference in the proportion of CD8⁺T and Treg cells among the three groups (P>0.05), while the proportions of CD4⁺T cells and PC in NDMM group were significantly higher than those in the CRMM group (P<0.05), the ratios of CD4⁺ to CD8⁺T in the NDMM and RRMM groups were significantly higher than those in the CRMM group (P<0.05). The expressions of PD-1, PD-L1 and CTLA-4 in CD8⁺ T cells was no significant difference among NDMM, CRMM and RRMM groups (P>0.05). While the expressions of PD-1, PD-L1 and CTLA-4 in CD4⁺ T cells and PC in the NDMM group were significantly lower than that in the CRMM group (P<0.05). There was significantly difference among the three groups in the expression of PD-1 in Treg cells, of which the NDMM group was significantly lower than that of the CRMM group (all P<0.05). The expressions of PD-1 and CTLA-4 in PC were significantly higher than those in CD8⁺ T, CD4⁺ T and Treg cells (P<0.05), the expression of PD-L1 in CD8⁺ T cells was significantly higher than that in CD4⁺ T and Treg cells (P<0.05). CONCLUSION There is a correlation between the immune status of multiple myeloma and the expressions of PD-1, PD-L1 and CTLA-4 in plasma cells and lymphocyte subsets in vivo.
