Objective To investigate the effects of VCAM-1 on migration and invasion of glioma cell lines . Methods The techniques of lentivirus pSGU6/GFP/Neo-based VCAM-1 shRNA and EF1 a-GFP/puro-based VCAM-1 expression vector, the scratch wound healing migration and transwell invasion assays , and the Western blot and cell staining were applied to observe the effects of VCAM-1 expression levels on migration and invasion of glioma cell line cells.There are four groups in T98G cells including control, vector, scramble and shRNA-VCAM-1 groups and three groups in U251 cells covering control, vector and VCAM-1 overexpressed groups ( n=6 per group) .Results The stabled glioma cell lines of T98 G cells with down-regulated VCAM-1 and U251 cells with VCAM-1 overexpression were established by using lentivirus-based VCAM-1 shRNA and expression vector.The ability of scratch wound healing (migration activity) decreased significantly (P<0.01) in T98G cells with lower VCAM-1 expression levels, while the migration activity was obviously improved in U251 cells with overexpressed VCAM-1 ( P <0.05 ) .Similarly, the invasion ability was significantly inhibited ( P <0.05) in T98G cells with silenced VCAM-1, as well as VCAM-1 overexpression could enhance the invasion ability of U251 cells ( P<0.01 ) .Conclusions VCAM-1 improves the migration activity and invasion ability of human glioma cell line cells.

This study was aimed to observe the body weight and behavioral changes of heart-spleen deficiency mouseandtoassesstheefficacyofLing-Qi-Jia (LQJ)oralsolutiononqi-supplementingandmind-tranquilizing. The heart-spleen deficiency syndrome mouse model was established by using loading swimming anddrugdaily.Thebodyweight,foodconsumption,intestinepropulsion,tailsuspensiontest (TST),forced swimmingtest (FST),sleepingtimeandtheamountofbrainneurotransmitterweredetected.Theresultsshowed that mouse suffered loading swimming and drug formed heart-spleen deficiency syndrome model, which were indicated by lowering body weight and food consumption, shortened time in FST, prolonged accumulative immobility time in TST, intestine propulsion hyperfunction, shortened sleeping time and lowering brain neurotransmitter amount. LQJ oral solution can obviously improve experiment indexes mentioned above. It was concluded that LQJ oral solution, which can improve insomnia due to heart-spleen deficiency, might had close relation to the efficacy of qi-supplementing and mind-tranquilizing. Meanwhile, changes of brain neurotransmitters might also be the material basis on its efficacy.

[ ABSTRACT] AIM:To prove the purinergic signaling mechanism of the neuroprotective action of hydrogen sulfide by observing the effects of sodium hydrosulfide ( NaHS) , a donor of hydrogen sulfide, on the cell viability, intracellular Ca2+concentration ( [ Ca2+] i ) and the change of membrane permeability in the PC12 cells injured by adenosine triphos-phate ( ATP) .METHODS: PC12 cells in logarithmic growth phase were randomly divided into 4 groups.In control group, the cells were cultured without ATP treatment.In ATP group, the cells were treated with ATP after cultured for 24 h.In NaHS+ATP group, the cells were incubated with NaHS for 30 min before treated with ATP, and NaHS always exis-ted in the reaction system.In KN-62+ATP group, the cells were pretreated with KN-62 for 30 min, and the other treat-ments were as the same as those in NaHS+ATP group.The cell viability was assessed by MTT assay.The [ Ca2+] i was detected by Fura-2/AM staining.The membrane permeability was observed by staining with fluorescent dye YO-PRO-1. RESULTS:ATP at concentration of 0.3 mmol/L showed no injury effect on the cells.However, the cell viability was dropped gradually in a dose-dependent manner as the ATP at doses of 1, 3, 5 and 10 mmol/L.The decline of cell viability by ATP was obviously reversed by 200 μmol/L of NaHS in the PC12 cells (P<0.05), but exasperated by 800μmol/L of NaHS (P<0.05).At the same time, ATP evoked the increase in [Ca2+]i in a dose-dependent manner, which was inhib-ited by NaHS ( P<0.05) .Furthermore, the YO-PRO-1 uptake induced by ATP in a dose-dependent and time-dependent manner was also reduced by NaHS ( P<0.05) .CONCLUSION:Hydrogen sulfide has protective effect on the PC12 cells injured by ATP.The mechanism may be related to the reverse of the increased [ Ca2+] i and YO-PRO-1 uptake.

Objective: To investigate the relationship between chemosensitivity to L-OHP and expressions of multidrug resistance (MDR) associated factors in lymph node metastases (LNMs) of gastric carcinoma. Methods: The chemosensitivity to L-OHP was measured by MIT assay, and the expressions of P-gp, GST-π, P53, Survivin and Bcl-2 were determined by immunohistochemistry in 54 paired primary tumor (PT) and LNMs of gastric carcinoma. Results: The inhibition rates of LNMs cells for L-OHP were lower than those of PT (P<0.05). The expressions of P-gp, GST-π and Bcl-2 were higher in LNMs than in PT (P<0.05), and no signifi-cant difference was found in the expression of P53 and Survivin between LNMs and PT (P>0.05). Positive cor-relations among P-gp, P53 and Bcl-2 were found in PT and LNMs (r=0.3424, 0.7123, 0.4548, P<0.05). There was no significant difference in the expression of GST-π and Survivin between PT and LNMs (P>0.05). There was statistically negative correlation between inhibition rates and expression of P-gp, GST-π, and Survivin in PT (P<0.05). In LNMs, only Survivin was negatively correlated with inhibition rates of L-OHP (P<0.05). Conclu-sion: The LNMs of gastric carcinoma are heterogeneous with PT in respect to chemosensitivity to L-OHP and expression of multidrug resistance associated factors. The main factors that affect chemosensitivity to L-OHP are also significantly different between PT and LNMs. Effective adjuvant chemotherapy after surgery and re-version to multidrug resistance (MDR) of gastric carcinoma depend on targeting the metastatic lesions of gas-tric carcinoma.

[Summary] The activities of 17α-hydroxylase and 17,20 lyase of cytochrome P450c17 were evaluated by ELISA in NCI-H295R cells after treatment with palmitate and oleate. The results showed that 0. 75 mmol/L plamitate did not influence the activity of 17α-hydroxylase, but increased the activity of 17, 20 lyase by 74. 3% ( P<0. 05). Oleate at the same concentration did not change the activity of 17,20 lyase. There were no significant changes in the protein expressions of P450c17, P450 oxidoreductase, and cytochrome b5 after treatment with palmitate and oleate. However,reactive oxygen species in cells were elevated by palmitate. The results suggest that exposure to palmitate may increase androgen production by inducing 17, 20 lyase activity of P450c17 in NCI-H295R cells, which is related with oxidative stress-mediated post-translational regulation of the enzyme.

Abstract: Objective　To investigate the distribution and drug resistance characteristics of pathogenic bacteria in patients with neutropenic acute leukemia (AL) and bloodstream infections (BSI). Methods　The clinical data of 258 neutropenic acute leukemia patients with bloodstream infections, who admitted to Shengjing Hospital of China Medical University from January 2016 to December 2021, were collected and analyzed for pathogenic bacteria and drug resistance. Results A total of 268 strains of pathogenic bacteria were isolated from 258 patients, including 180 strains of gram-negative bacteria (67.16%), 61 strains of gram-positive bacteria (22.76%), and 27 strains of fungi (10.07%). Gram-negative bacteria were mainly Klebsiella pneumoniae (53/268, 19.78%), Escherichia coli (49/268, 18.28%) and Pseudomonas aeruginosa (41/268, 15.30%). Gram-positive bacteria were mainly coagulase negative Staphylococcus (31/268, 11.57%) and Staphylococcus aureus(17/268, 6.34%). The main fungi were Candida tropicalis (25/268, 9.33%). Escherichia coli (33/268, 12.31%) was the most common pathogen isolated from acute myeloid leukemia (AML), followed by Pseudomonas aeruginosa (25/268, 9.33%), coagulase-negative Staphylococcus (18/268, 6.72%) and Candida tropicalis (18/268, 6.72%). Klebsiella pneumoniae (35/268, 13.06%) was the most common pathogen isolated from acute lymphoblastic leukemia (ALL),followed by Pseudomonas aeruginosa (15/268, 5.60%) and Escherichia coli (14/268, 5.22%). The resistance of Gram-negative bacteria to piperacillin/tazobactam, cefoperazone/sulbactam, imipenem, meropenem, ertapenem, amikacin, cefoxitin, amoxicillin/clavulanic acid was low. Gram-positive bacteria were sensitive to linezolid and vancomycin. Candida was sensitive to flucytosine, amphotericin B and itraconazole. Conclusions　In patients with granulosa after AL chemotherapy combined with BSI, the pathogenic bacteria isolated from AML are diverse, and the pathogenic bacteria isolated from ALL are mainly gram-negative bacteria. Pathogenic bacteria have different degrees of drug resistance to commonly used antibacterial drugs, so it is important to strengthen the monitoring of the distribution of pathogenic bacteria and the change of drug resistance and rational use of antibacterial drugs to minimize the death of patients.

OBJECTIVETo investigate the genetic polymorphism of 9 short tandem repeats (STR) gene loci, namely CSFIPO, TPOX, TH01, D16S539, D7S820, D13S317, F13A01, FESFPS and vWA in Chinese Korean population in Mudajiang area.

METHODSAmplified fragment length polymorphism (Amp-FLP) method was used to get the allele frequency distribution.

RESULTSThe genotype distributions of the 9 STR loci are conformed to Hardy-Weinberg equilibrium by chi(2) test analysis. The total accord frequency, the accumulated total discrimination power and the the accumulative excluding probability of paternity were calculated.

CONCLUSIONThe result suggested that all 9 gene loci have high power of excluding probability of paternity and individual identification. They can be used in paternity testing and individual identification for forensic medicine. The gene frequencies of CSFIPO, TPOX and TP01 gene loci have significant differences between the Korean population in Mudanjiang area and those in Yanji area, but there is no difference in gene loci of D7S820, D17S317 and vWA.
