Objective To investigate the correlation between the expression of vascular endothelial growth factor-C(VEGF-C) and lymph node metastasis in gastric cancer. Methods The expression of VEGF-C was detected in 30 pairs of fresh primary gastric cancers and their adjacent normal tissues from the same patients by semi-quantitative reverse transcriptase-polymerase chain reaction (RT-PCR) and immunohistochemistry. Automated image analyzer was used to quantify VEGF-C expression, which was reflected by positive index (PI). Results VEGF-C was highly expressed in gastric cancer cells,whilst its expression was undetectable in adjacent normal tissues. VEGF-C expression was higher in lymph node metastasis group(PI=1.345?0.079) and lymphatic invasive(PI=1.315?0.037) group than that in no-metastasis group(PI=1.156?0.045) and no-invasive group (PI=1.154?0.043)(P

OBJECTIVE:To investigate the characteristics and related factors of drug-induced hyperkalemia,present preven-tive measures and provide reference for the rational drug use. METHODS:46 literatures of individual cases and group cases of drug-induced hyperkalemia publicly reported in domestic medical journals from 1979 to 2014 were collected and analyzed statistical-ly,including 66 cases. RESULTS:66 cases with drug-induced hyperkalemia were mainly involved in cardiovascular drugs and im-munosuppressants. Most of them were improved after drug withdrawal and symptomatic treatment,and 2 cases died. CONCLU-SIONS:Drug-induced hyperkalemia are potentially dangerous. It is necessary to be vigilant,prevent and control timely and reduce the incidence of severe adverse reactions.

Objective To study the role of OIf-1/EBF associated zinc finger protein (OAZ),a transcription factor encoded by a positional systemic lupus erythematosus (SLE) candidate gene,in the function of mesenchymal stem cells (MSC) of SLE patients by silencing this gene.Methods OAZ mRNA levels of bone marrow MSC obtained from 5 SLE patients and 5 healthy controls were detected by real-time PCR.Bone marrow MSC obtained from 6 SLE patients were incubated with specific siRNAs for 3 days,then cells were harvested for OAZ measurement,Idl-3 and CCL2 mRNA levels were tested by real-time PCR,and levels of CCL2 were detected in culture supernatants using ELISA.Differences between groups were analyzed using t-test or MannWhitney test.Results ① OAZ mRNA levels of bone marrow MSC were significantly elevated in SLE patients (0.013±0.016) compared to healthy controls (0.001±0.000,P=0.009).② After OAZ silencing,the expression levels of OAZ,Id1,Id2 and ld3 mRNA were significantly decreased (△Ct 10.3±0.7,15.2±1.6,8.1±1.4,10.5±0.6 vs 8.7±0.7,14.1±1.2,7.1±1.5,9.8±0.6) (P all ＜0.05).③ Both the expression levels of CCL2 mRNA (△Ct 2.2±1.1 vs 3.0±1.1 ) and the levels of CCL2 protein in culture supernatants [(341±29) pg/ml vs (304±19) pg/ml] were significantly increased in OAZ silencing group comparing to those in the control group (P all ＜0.05).Conclusion OAZ gene expression is significantly elevated in bone marrow MSC of SLE patients.OAZ may affect autoantibody production in SLE patients by regulating CCL2 expression.

ObjectiveWith a GcneChip(R) cxpression analysis,98 known gencs and 31 exprcssed sequence tags (ESTs) were found to be differentially expressed between KK/Ta and BALB/c kidneys.To further screen the susceptibility genes for diabetic nephropathy,the temporal and spatial expression patterns of differentially expressed gene-adipsin were investigated.MethodsThe body weight,blood glucose,urinary albumin/creatinine ratio,and renal pathological changes of KK/Ta and BALB/c mice were measured at the 7,20,28 and 36 weeks of age.Total RNA was extracted from the kidney,heart,liver,lung,and brain.The temporal and spatial expression patterns of adipsin in diabetic KK/Ta mice were examined by competitive RT-PCR.The correlation analysis between adipsin expression and albuminuria level was carried out.ResultsThe mRNA expression of adipsin was found in the kidney,heart,lung,and brain,but not in liver.The expression of adipsin in diabetic KK/Ta mice at 20 weeks of age was significantly down-regulated in kidney,heart,and lung than that in age-matched BALB/c mice,and unaltered in brain.Adipsin expression in KK/Ta kidneys was significantly down-regulated with aging and negatively correlated to urinary albumin/creatinine ratio( r =-0.807,P ＜ 0.05).ConclusionsThe expression of adipsin mRNA was downregulated in kidney,heart,and lung in diabetic state.Adipsin expression in KK/Ta kidneys was negatively correlated to urinary albumin/creatinine ratio.It might be a candidate gene for diabetic nephropathy.

Objective:To explore the use of internet-based continuous visual recognition task (MemTrax test, MTX) as a rapid screening tool for amnestic mild cognitive impairment (aMCI).Methods:Sixty-four patients with aMCI and 64 individuals with normal cognition as healthy controls were enrolled respectively from Department of Neurology and Health Examination Center of the First Affiliated Hospital of Kunming Medical University from August 2018 to December 2019. Montreal Cognitive Assessment (MoCA) scale and MTX were adopted to assess the cognitive function of all subjects. The total adjusted MoCA scale score, correct rate of MTX, reaction time of MTX and MTX score were obtained and statistically analyzed.Results:The adjusted MoCA scale scores of aMCI patients and healthy controls were 19 (14, 24) and 26 (24, 27; Z=6.795), the correct rate of MTX of aMCI patients and healthy controls were 74% (60%, 80%) and 88% (84%, 94%; Z=8.359), and the MTX score of aMCI patients and healthy controls were 51.11±14.07 and 70.56±14.91 ( t=7.590), respectively, all with statistically significant difference ( P<0.001). Reaction time of MTX of aMCI patients and healthy controls was 1.401 (1.253, 1.590) s and 1.277 (1.163, 1.410) s, respectively ( Z=3.083, P<0.01). After adjustment for age, physical or mental occupation, exercise, hypertension, hyperlipidemia, stroke, sleep time, as well as smoke, the linear regression showed that the aMCI patients had a significant decrease of adjusted MoCA score, correct rate of MTX and MTX score ( P<0.001), and an extension of reaction time of MTX ( P=0.071), compared with the controls. By MTX and MoCA scale assessment, the best cutoff value was 81% for correct rate of MTX and 23 for adjusted MoCA scale score respectively for the prediction of aMCI (with sensitivity of 79.7%, 93.8% respectively, and specificity of 68.8%, 82.8% respectively). The area under the curve (AUC) of correct rate of MTX was 0.93 (95% CI 0.89-0.97, P<0.001), and the AUC of adjusted MoCA score was 0.85 (95% CI 0.78-0.91, P<0.001). There was a statistically significant difference in paired comparison of the two AUCs (χ2=4.620, P<0.05). Conclusion:MTX acts better for the detection of aMCI than MoCA scale, and correct rate of MTX<81% can be considered as the existence of MCI.

Objective To investigate the regulation of protein kinase C(PKC) to the expression of β-1,4-galactusyhransferase- Ⅰ ( β-1,4-GalT- Ⅰ ) and the influence on cytoskeleton and adherence ability of human umbilical vein endothelial cells(HUVECs) when stimulated by lipopolysaccharide (LPS). Methods Cultured HUVECs were pretreated by various PKC inhibitors or phorbol 12-myristate 13-acctate( PMA), an excitomotor of PKC respectively for 30 min, then stimulated by LPS for 4 h. β-1,4-GalT-Ⅰ expression were detected by RT-PCR and Western blot, expression of β-1,4-galactosylated carbohydrate chains and cytoskeleton were assayed by immumofluorescence, and adherence ability of HUVECs was observed by endothelialmonocyte cell adherence test. Results Up-regulated expression of β-1,4-GalT- Ⅰ and β-1,4-galactosylated carbohydrate chains in HUVECs stimulated by LPS were suppressed by PKC inhibitors and increased by PMA. F-actin and β-1,4-GalT- Ⅰ were partly co-localized in HUVECs. PKC inhibitor inhibited the effect of LPS on the distribution of F-actin and β-1,4-GalT- Ⅰ. Adherence ability of HUVECs enhanced by LPS was significantly suppressed by PKC inhibitor. Conclusion PKC signal transduction pathway may participate in regulating β-1,4-GalT-Ⅰ expression in endothelial cells stimulated by LPS. Furthermore, polytypes of PKC may participate in this regulating process; PKC might regulate cytoskeleton reorganization and adherence ability of EC through β-1,4-GalT-Ⅰ during inflammation.
