Objective:To evaluate the effects and underlying mechanisms of metabolites derived from the kidney-reinforcing, blood circulation-activating, and collateral dredging decoction on the proliferation of multiple myeloma (MM) KM3 cells.Methods:MM KM3 cells in the logarithmic growth phase were treated with 3%, 6%, 9%, or 12% metabolites of kidney-reinforcing, blood circulation-activating, and collateral dredging decoction. Cell viability was assessed using the CCK-8 assay. Apoptosis and necrosis were evaluated using flow cytometry and TUNEL staining. Mitochondrial and cellular ultrastructural changes were examined using transmission electron microscopy. mRNA and protein expression levels of dynamin-related protein 1 (Drp1), mitochondrial fission protein 1 (Fis1), mitochondrial fission factor (MFF), PTEN-induced kinase 1 (Pink1), and E3 ubiquitin ligase (Parkin) were determined through quantitative real-time PCR and western blotting. High-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) combined with network pharmacology, was utilized for reverse verification of the pharmacodynamic mechanisms and therapeutic targets underlying the anti-MM activity of this decoction.Results:The metabolites of the kidney-reinforcing, blood circulation-activating, and collateral dredging decoction inhibited KM3 cell proliferation and induced apoptosis in a dose-dependent manner. Transmission electron microscopy revealed increased mitochondrial fission and autophagic structures, with effects intensifying at higher metabolite concentrations. mRNA and protein expression of Drp1, Fis1, MFF, Pink1, and Parkin were significantly upregulated in treatment groups compared to controls ( P<0.05), with the most pronounced effects observed in the 12% metabolite group ( P<0.01). HPLC-MS/MS identified 121 bioactive compounds in BHTF, which shared 474 overlapping targets with MM. Enrichment analysis suggested that BHTF exerts antitumor effects primarily through apigenin, palmatine, and other key components by modulating TNF, NF-κB, and mitophagy pathways. Conclusion:The kidney-reinforcing and blood circulation-activating and collateral dredging decoction suppresses the proliferation of MM KM3 cells, potentially through mechanisms involving the regulation of mitochondrial dynamics and induction of autophagy.

Objective:
To describe the distribution and drug resistance of pathogens at hematology department of Jiangsu Province from 2014 to 2015 to provide reference for empirical anti-infection treatment.
Methods:
Pathogens were from hematology department of 26 tertiary hospitals in Jiangsu Province from 2014 to 2015. Antimicrobial susceptibility testing was carried out according to a unified protocol using Kirby-Bauer method or agar dilution method. Collection of drug susceptibility results and corresponding patient data were analyzed.
Results:
The separated pathogens amounted to 4 306. Gram-negative bacteria accounted for 64.26%, while the proportions of gram-positive bacteria and funguses were 26.99% and 8.75% respectively. Common gram-negative bacteria were Escherichia coli (20.48%) , Klebsiella pneumonia (15.40%) , Pseudomonas aeruginosa (8.50%) , Acinetobacter baumannii (5.04%) and Stenotropho-monas maltophilia (3.41%) respectively. CRE amounted to 123 (6.68%) . Common gram-positive bacteria were Staphylococcus aureus (4.92%) , Staphylococcus hominis (4.88%) and Staphylococcus epidermidis (4.71%) respectively. Candida albicans were the main fungus which accounted for 5.43%. The rates of Escherichia coli and Klebsiella pneumonia resistant to carbapenems were 3.5%-6.1% and 5.0%-6.3% respectively. The rates of Pseudomonas aeruginosa resistant to tobramycin and amikacin were 3.2% and 3.3% respectively. The resistant rates of Acinetobacter baumannii towards tobramycin and cefoperazone/sulbactam were both 19.2%. The rates of Stenotrophomonas maltophilia resistant to minocycline and sulfamethoxazole were 3.5% and 9.3% respectively. The rates of Staphylococcus aureus, Enterococcus faecium and Enterococcus faecalis resistant wards vancomycin were 0, 6.4% and 1.4% respectively; also, the rates of them resistant to linezolid were 1.2%, 0 and 1.6% respectively; in addition, the rates of them resistant to teicoplanin were 2.8%, 14.3% and 8.0% respectively. Furthermore, MRSA accounted for 39.15% (83/212) .
Conclusions
Pathogens were mainly gram-negative bacteria. CRE accounted for 6.68%. The rates of Escherichia coli and Klebsiella pneumonia resistant to carbapenems were lower compared with other antibacterial agents. The rates of gram-positive bacteria resistant to vancomycin, linezolid and teicoplanin were still low. MRSA accounted for 39.15%.

Objectives To investigate the effects of phytosterol intensive diet intervention on blood glucose, blood lipid and liver function in patients with type 2 diabetes mellitus combined with nonalcoholic fatty liver disease(NAFLD). Methods Patients with NAFLD admitted to the department of endocrinology, the Affiliated Hospital of Jiangsu University from January 2016 to June 2016 were recruited.We divided the groups according to the order of patient admission,with patients admitted from January to March who received conventional diabetes mellitus low-fat diet enrolled as control group,and patients admitted from April to June received extra phytosterol intensive diet on the basis of conventional diabetes mellitus diet as treatment group. The changes of blood glucose, blood lipid and liver function between two groups with a follow-up of six months before and after intervention were compared and analyzed. Results After intervention,the levels of fasting blood sugar(FPG)and blood glucose(2hPG), glycosylated hemoglobin (HbA1c), cholesterol (TG), triglyceride (TC), alanine aminotransferase (ALT) of patients in control group(11.13 ± 3.17)mmol/L,(18.65 ± 6.21)mmol/L,(9.82 ± 1.69)%,(2.81 ± 1.43) mmol/L、(5.40 ± 1.14)mmol/L,77.27%(51/66),which were lower than those before intervention((8.51 ± 2.83)mmol/L,(10.39 ± 3.62)mmol/L,(7.78 ± 1.46)%,(2.18 ± 1.13)mmol/L,(4.99 ± 1.04)mmol/L, 90.91%(60/66),P<0.05,and FPG,2 hPG,HbA1c,TG,TC,LDL-C,ALT and aspartate aminotransferase (AST) in the experimental group were(11.32 ± 3.64)mmol/L,(20.09 ± 4.83)mmol/L,(9.70 ± 2.12)%, (2.68 ± 1.74)mmol/L,(5.16 ± 1.10)mmol/L,(3.18 ± 0.92)mmol/L,(70.27)%(52/74),(86.49)%(64/74), which were significantly lower than those before intervention((7.37 ± 2.08)mmol/L,(9.20 ± 3.35)mmol/L, (6.75 ± 0.99)%,(1.86 ± 1.13)mmol/L,(4.69 ± 1.06)mmol/L,(2.67 ± 0.72)mmol/L, 91.89%(68/74), 98.65%(73/74), P<0.05, and the differences was statistically significant(t=4.584,9.329,7.349,2.823, 2.140,χ2=4.587, P<0.01 or 0.05 in control group;t=8.106,15.715, 10.826,3.393,2.651,3.755,P<0.01 in experimental group). The levels of FPG, 2 hPG and HbA1c were significantly lower in the experimental group compared with those in control group after intervention(P<0.05),and the positive-to-negative rate of fatty liver were found to be significantly higher (33.8%,25/74) than that (9.1%,6/66) in controls(P<0.05).There were not significantly differences in the level of TG,TC,high density lipoprotein(HDL-C), LDL-C, ALT and AST between the control group and experimental group(P>0.05). Conclusions Phytosterol intensive diet intervention can effectively reduce LDL-C,AST and the blood glucose level of type 2 diabetes patients with NAFLD, improving the positive-to-negative rate of fatty liver. Phytosterol intensive diet intervention can effectively reduce LDL-C, AST and the blood glucose level of type 2 diabetes patients with NAFLD,improve the positive-to-negative rate of fatty liver.

This review systematically introduces the functional connections among cardiovascular centers from spinal cord to cortex, and the mechanisms underlying pressor or depressor response of these cardiovascular centers, including the pathways, transmitters and receptors involved. The pressor or depressor response of these cardiovascular centers is mainly mediated by RVLM-sympathetic vasoconstrictor nerve system.
