[Abstract ] Forkhead box(Fox) M1, as a member of the Fox transcription factor family, overexpresses in many kinds of canc-ers and is related to a variety of oncogenic signaling pathways.It plays an important role in the occurrence, progression and metastasis of cancer.FoxM1 has been a new target for cancer therapy research.

Objective The invasion and metastasis of colon cancer often leads to treatment failure and mortality in patients . Our research is to investigate the influence of FoxM 1 to malignant human colon cancer line . Methods In two human colon cancer lines, the protein and mRNA expression levels of FoxM 1 were analyzed with the application of RT-PCR and Western blot , from which high-expressed HT-29 and low-expressed HCT-116 were determined.The expression of FoxM1 was down-regulated by RNA interfering in HT-29 and up-regulated by constructing overexpression transgenic line in HCT-116.The proliferation of the above cells was assayed by healing method;while the metastasis and invasion ability were examined by Transwell chamber assay . Results Two colon cancer lines were selected with high-expression or low-expression of FoxM1 separately named HT-29 and HCT-116.Application of PEX-2-FoxM1 raised after HCT-116 cells express FoxM1, cell scratches in HCT-116 experimetal group ([70.92 ±1.48]%) compared with HCT-116 control group([16.92 ±4.05]%)and HCT-116 blank control group([16.66 ±2.63]%) will markedly enhance its capabil-ity of healing (P<0.05), Transwell Chambers in membrane cells in HCT-116 experimetal group (186.0 ±6.8) compared with HCT-116 control group(42.0 ±2.0) and HCT-116 blank control grou (37.0 ± 2.2)was increased (P<0.05).On the other hand, the applied pG-PH-shFoxM1 can reduce FoxM1 expression in HT-29 cell, cell scrat-ches healing ability in HT-29 experimetal group ( [ 10 .37 ± 3.86]%) compared with HT-29 control group([34.63 ±2.35]%)and HT-29 blank control group([67.36 ±2.61]%) decreased significantly (P<0.05), Transwell Chambers in membrane cells in HT-29 experimetal group (53.0 ±1.8)compared with HT-29 control group(95.0 ±2.2)and HT-29 blank control grou(118.0 ±4.0) was also reduced (P<0.05). Conclusion The expression of FoxM1 is in close relation to the invasion and metastasis of CRC .The fact that the siRNA interfering FoxM1 could effectively inhibit the proliferation, metastasis and invasion, suggesting FoxM1 could po-tentially be a new molecular target for inhibiting the proliferation of human colon cancer line .

Objective To investigate the levels of the mRNA expression of TIM-3 and Galectin-9 in peripheral blood mono-cytes (PBMCs)of acute exacerbation asthma patients and their clinical significances.Methods 60 patients with acute exac-erbation asthma (eliminating 15 cases of non-conform to the regulations)and 30 cases of healthy subjects were collected from January to October of 2014.Used fluorescence quantitative real-time reverse transcription-polymerase chain reaction to measure the mRNA expression of TIM-3 and Galectin-9 in PBMCs of patients with asthma and healthy controls.Results The expression of TIM-3,Galectin-9 and IFN-γmRNA in the PBMCs from acute exacerbation asthma patients were all ab-normally higher than healthy controls (U =458.5,P =0.019;U =437.5,P =0.010;U =260,P <0.001).There were statis-tically significant differences between them.Conclusion TIM-3/Galectin-9 pathway may participate in the occurrence,devel-opment of asthma.TIM-3 or (and)Galectin-9 may prove to be an important target for treatments to asthma.

OBJECTIVE To determine the drug resistance phenotype and genotype of plasmid-mediated AmpC ?-lactamase in Klebsiella pneumoniae isolated from Harbin.METHODS Isolates of K.pneumoniae with an inhibition ring to cefoxitin of ≤18 mm diameter were used.Antimicrobial susceptibilities were determined by disc diffusion method.AmpC genes were detected by PCR with six pairs of primers.RESULTS Sixty-three isolates had an inhibition ring to cefoxitin of ≤18 mm diameter and 26(11.3%)were detected to be AmpC-producing in a total of 231 clinical isolates of K.pneumoniae.Seventy-six percent,70.2%,53.8%,50.5%,57.7%,38.5% and 7.7% of AmpC-producers were resistant to cefoxitin,cefotaxime,ceftazidime,amoxicillin/clavulanic cid,ciprofloxacin,amikacin and imipenem,respectively.ACT,DHA and CIT types of AmpC beta-lactamase were detected in 13,8 and 5 isolates,respectively.No ACC,MOX and FOX were detected.CONCLUSIONS The AmpC ?-lactamase in Harbin is mainly in the types of ACT,DHA and CIT.AmpC-producing K.pneumoniae shows decreased susceptibilities to cefoxitin and third generation cephalosporins.

Objective To establish a regression equation for risk factors of refeeding syndrome (RFS) in critically ill elderly patients and analyze the relevant intervention measures. Methods Clinical materials of 154 critically ill elderly patients treated in Intensive Care Unit (ICU) from January 2021 to March 2023 were retrospectively analyzed, and they were divided into RFS group (n=51) and non-RFS group (n=103) according to incidence condition of RFS. The influencing factors of RFS were analyzed by Logistic regression model; the predictive values of predictors for RFS were analyzed by receiver operating characteristic (ROC) curve; the relevant Logistic regression equations were constructed and verified, and relevant nursing interventions were formulated. Results The incidence of RFS in critically ill elderly patients was correlated with the Acute Physiology and Chronic Health Evaluation Ⅱ (APACHE Ⅱ) score, the Nutritional Risk Screening 2002 (NRS2002) score, invasive mechanical ventilation, fasting time before feeding, D-dimer level, nutritional intake methods, and pre-feeding blood phosphorus, potassium and magnesium levels (P < 0.05). Logistic regression analysis showed that APACHE Ⅱ score, NRS2002 score, nutrient intake methods and pre-feeding blood phosphorus and potassium levels were the independent risk factors of RFS in critically ill elderly patients (P < 0.05). The ROC curve results showed that the values of area under the curve (AUC) of APACHE Ⅱ score, NRS2002 score, nutritional intake methods, pre-feeding blood phosphorus and potassium levels, and the combined predictor in predicting the incidence of RFS in critically ill elderly patients were 0.754, 0.723, 0.707, 0.783, 0.774 and 0.859, respectively (P < 0.05). The Logistic regression equation for RFS was as follow: L=0.085×APACHE Ⅱ score-0.337×NRS 2002 score+0.537×nutrient intake methods-0.776×pre-feeding blood phosphorus level-0.207×pre-feeding blood potassium level+0.942. The predictive value of this equation was good, and targeted nursing interventions could be formulated based on this equation. Conclusion The regression equation of risk factors can be used for clinical prediction of the RFS risk in critically ill elderly patients, and clinical nursing interventions can be formulated based on the regression equation to prevent the occurrence of RFS.

OBJECTIVE: To establish the rat model of depression and observe its morphological changes and nerve growth factor (NGF) expression in nasal mucosal. METHOD: Thirty SD rats were divided into depression model group and normal controls with 15 rats in each group. The rat depression model were made by application of chronic unforeseeable medium stress stimulating. Behavior change were observed with open box experiment(open field) and humoral consumption-experiments (sucrose consumption), After being sacrificed, the nasal mucosal were taken for HE and NGF immunohistochemical study. The difference of nasal mucosal NGF protein between two groups were examined with medical digital image analysis technology. RESULT: There were no swelling and inflammatory cells infiltrating in nasal mucosal of normal group, but 53% nasal mucosal of depression model were observed such morphological changes. Th NGF immunohistochemical staining were negative in normal group but positive in 53% depression model group. There were significant differences between two groups (P < 0.01). CONCLUSION Depression rats may appear rhinitis symptoms under long-term stress stimulating. NGF may exert immunoregulatory effects, stimulate the immune cell proliferation and gathering, induce various media release, increase the sensitivity of nerve fibers itself and the producing of neuropeptide, promote the formation of nerve source inflammation and increase the reactivity of nasal mucosa.

The levels of serum IL-10 in patients with qi stagnation and blood stasis syndrome, damp-heat obstruction syndrome and cold-damp obstruction syndrome were higher than those in patients with liver-kidney deficiency syndrome, and the differences were statistically significant ( P<0.05) . Conclusions:The curative effect of scraping in the treatment of LDH is definite, and the curative effect is better for excessive syndromes.

Objective:To systematically review the effects of the traditional Chinese medicine compound based on astragalus and angelica on bone marrow suppression after chemotherapy.Methods:Randomized controlled trials (RCTs) about the traditional Chinese medicine compound based on astragalus and angelica for bone marrow suppression after chemotherapy for malignant tumors were retrieved from Cochrane Library, PubMed, Web of Science, CINAHL, OVID, SinoMed, CNKI, VIP, and Wanfang Databases. The search period was from the establishment of the database to September 2019. The literatures were screened and the data were extracted independently by two researchers and RevMan 5.3 was used for Meta-analysis.Results:Totally 15 RCTs were included, involving 1 019 patients. Meta-analysis results showed that there were statistically significant differences in peripheral blood leukocytes [ SMD=1.32; 95% CI (0.76, 1.89) ; P<0.000 01], platelets [ MD=25.05; 95% CI (8.00, 42.10) ; P=0.004], hemoglobin [ MD=24.14; 95% CI (16.34, 31.94) ; P<0.000 01] and clinical symptoms [ RR=1.38; 95% CI (1.25, 1.52) ; P<0.000 01] between the chemotherapy group, the chemotherapy combined with the western medicine group and the traditional Chinese medicine compound group. Conclusions:The traditional Chinese medicine compound based on astragalus and angelica can improve the level of peripheral blood cells, reduce bone marrow suppression, and improve clinical symptoms and quality of life of patients with cancer after chemotherapy. However, due to the low quality of the included literature and the large heterogeneity of some of the results, more rigorously designed high-quality RCTs are needed for further verification.
