Objective To evaluate the influence of family intervention mode in patients with schizophrenia characterized by negative symptoms.Methods A total of 120 cases of hospitalized patients with schizophrenia characterized by negative symptoms were randomly divided into the observation group and the control group with 60 cases in each group.The observation group received treatment through family intervention mode based upon routine care,while the control group used routine care.Influences were assessed with Nurses’ Observation Scale for Inpatient Evaluation (NOSIE) and the Scale for Assessment of Negative Symptoms (SANS) before treatment and at the end of 6th,12th week treatment.Results No significant difference of NOSIE score or SANS score were found upon admission between the observation group and the control group.At the end of the 6th week or the 12th week,total and all factors’ scores of the NOSIE and SANS of both groups were better compared with pretreatment,the observation group was significantly better than the control group.Conclusions Family intervention model could significantly relieve the negative symptoms of schizophrenia,improve the patients’ clinical efficacy and is an effective adjunctive therapy for schizophrenia.

Objective To investigate the protective effect of agmatine (AGM) against peritoneal inflammatory response and neutrophil (PMN) infiltration induced by zymosan (ZYM) in mice. Methods Thirty-six adult male C57BL/6 mice were randomly divided into sham group, model group, and AGM treatment group. Peritonitis model was reproduced by intra-peritoneal injection of 1 mg/mL ZYM (0.5 mL), while equivalent phosphate buffer saline (PBS) was given to sham group. 200 mg/kg AGM was injected into peritoneal cavity after ZYM challenge in AGM treatment group. Six mice in each group were sacrificed at 2 hours and 6 hours, respectively, after reproduction of the model. Blood sample and peritoneal lavage fluid (PLF) were collected. The levels of keratinocyte-derived chemokine (KC), macrophage inflammatory protein 2 (MIP-2), tumor necrosis factor-α (TNF-α), interleukins-6 (IL-6) in serum and PLF were determined by enzyme linked immunosorbent assay (ELISA). The number of leukocytes and PMN in PLF were determined by hemocytometer and flow cytometry, respectively. Results Compared with sham group, all serum and PLF levels of KC, MIP-2, TNF-α and IL-6 were greatly elevated at 2 hours after ZYM injection in model group, while AGM treatment could dramatically reduce the levels of the above-mentioned cytokines in serum and PLF as compared with those of the model group [serum KC (ng/L): 990.7±137.9 vs. 2 053.2±262.7, MIP-2 (ng/L): 642.2±124.4 vs. 1 369.7±146.5, TNF-α (ng/L): 608.6±38.1 vs. 1 044.7±101.0, IL-6 (ng/L): 1 058.2±129.1 vs. 1 443.3±190.1; PLF KC (ng/L): 7 462.3±839.6 vs. 12 723.5±1 515.7, MIP-2 (ng/L): 1 570.8±193.4 vs. 3 471.4±384.7, TNF-α (ng/L): 1 115.8±156.7 vs. 1 499.2±231.2, IL-6 (ng/L): 2 646.5±223.2 vs. 3 126.7±291.4; all P < 0.05]. The expressions of KC, MIP-2 and TNF-α at 6 hours were significantly lower than those at 2 hours in model group and AGM treatment group, but IL-6 levels were further increased. The levels of KC and MIP-2 in serum and PLF at 6 hours were decreased to the levels of sham group. At 6 hours after the reproduction of the model, the number of total inflammatory cells and PMN of PLF in the model group was significantly higher than those of the sham group. In contrast, AGM notably lowered the number of inflammatory cells and PMN in peritoneal fluid after ZYM attack [total inflammatory cells (×109/L): 14.7±1.1 vs. 2.0±0.4, 10.1±1.2 vs. 14.7±1.1; PMN (×109/L): 11.37±1.22 vs. 0.18±0.05, 7.69±0.57 vs. 11.37±1.22, all P < 0.05]. Conclusion AGM can effectively alleviate acute peritoneal inflammatory injury induced by ZYM, mainly through reducing the secretion of inflammatory mediators and chemokines, and inhibiting the infiltration of leukocytes and neutrophils.

PURPOSE: The long non-coding RNA H19, a conservatively imprinted gene, acts as a molecular sponge for the let-7 family, which has been identified as a set of tumor suppressors. However, the combined prognostic value of H19 and let-7a signature in breast cancer patients remains unclear. METHODS: In this research we assessed the prognostic value of the combined H19 and let-7a signature in breast cancer patients by retrospectively reviewing that data of 79 patients who underwent neoadjuvant chemotherapy; we also investigated the expression and function of H19 in breast cancer cell lines in vitro. Survival data were calculated using the Kaplan-Meier method and compared using the log-rank test. Univariate and multivariate survival analyses were conducted using the Cox proportional hazards regression method. As determined using X-tile, the optimal cutoff value for the risk score to assess progression-free survival (PFS) based on the combined signature was –0.1. RESULTS: Patients with an overall positive treatment response had higher let-7a and lower H19 levels. In addition, let-7a expression was negatively correlated with H19 expression. Patients with a risk score of >–0.1 had shorter overall survival and PFS. In vitro data showed that chemoresistant cell lines exhibit higher H19 and lower let-7a levels and knockdown H19 restores paclitaxel sensitivity. CONCLUSION: Our results suggest that the combined let-7a and H19 signature is a novel prognostic factor for breast cancer patients treated with neoadjuvant chemotherapy.

Objective To investigate the bacterial resistance in nationwide and understand the distribution of bacterial and resistance trend.MethodsThe 6507 clinical isolates were collected from 19 hospitals in 17 cities.The susceptibility tests were performed using agar dilution method recommended by Clinical and Laboratory Standards Institute (CLSI) in central laboratory.The values of MIC50,MIC90 and MICrange were calculated by SPSS 17.0 and the susceptibilities of isolates to antimicrobial agents were determined by using CLSI (2010) guideline.Of all 6507 isolates,4691 strains were collected from target wards and 1816 were isolated from others wards.ResultsAmong 4691 strains,1156 were Gram-positive (24.6％ ) and 3535 were Gram-negative (75.4％).Based on the minimum inhibitory concentration results,the prevalence of methicillin resistant Stapylococcus aureus and methicillin resistant Stapylococcus epidermidis are 51.6％ ( 325/630 ) and 87.0％ ( 228/262 ) respectively.Staphylococci showing intermediate or full resistance to vancomycin were not observed. Coagulase negative Staphylococci showed 2.5％ (16/642)intermediate rate and 1.6％ ( 10/642 ) full resistance rate to teicoplanin,and showed 0.5％ ( 3/642 )resistance rate to linezolid.Antibiotic resistance rate of Enterococcus faecalis to ampicillin was 17.1％(19/111),while the resistance rate of Enterococcus faecium to ampicillin reached up to 85.0％(164/193).Three Enterococcus faecium were resistant to glycopeptides.The prevalence of penicillin resistance Streptococcus pneumoniae and penicillin intermediate Streptococcus pneumoniae were 41.2％ ( 145/352) and 37.2％ (131/352) respectively based on oral penicillin criterion,while the prevalence were 0.0％ (0/352) and 6.0％(21/352) based on vein to non-meningitis criterion.A vast majority of Enterobacteriaceae maintained high susceptibility to carbapenems,with resistance rate less than 2.0％.In addition,tigecycline,moxalactam,fosfomycin and amikacin displayed desirable antibacterial activity against Enterbacteriaceae,and resistance rates to these drugs were all less than 10.0％.For non-fermenting Gramnegative isolates,resistance rate of Pseudomonas aeruginosa and Acinetobacter baumannii to imipenem were 23.1％ ( 139/601 ) and 53.5％ (419/784) respectively.Resistance rate of Acinetobacter baumannii was much higher than that during the period 2007 - 2008.Colistin,tigecycline,minocycline and fosfomycin demonstrated good antibacterial activity against Acinetobacter baumannii in vitro.Conclusions Compared with MOHNARIN 2007 -2008year surveillance results, significant increase in resistance rate of Acinetobacter baumannii was demonstrated.Resistant strains to linezolid and tigecycline were found.Bacterial resistance has been a widespread problem in our country,which requires much more attention.
