Impaired glutamate uptake function of astrocytes associated with accumulation of extracellular glutamate is a well-documented feature of amyotrophic lateral sclerosis (ALS). Enhancing the uptake function of astrocytic glutamate transport 1 (GLT1) may be a potential treatment for this disease. Human adipose-derived stem cells (hADSCs) are capable of secreting a large number of cytokines which exhibit diverse pharmacological effects. Therefore, we investigate the influence of the soluble factors released by hADSCs on the GLT1 in primary astrocytes cultured from SOD1G93A mice, a widely studied mutant human SOD1 transgenic model of ALS. Our data indicate that soluble factors from hADSCs significantly upregulate the expression of GLT1 in SOD1G93A-bearing astrocytes, which result in enhanced glutamate uptake function. The upregulation of GLT1 is accompanied by the inhibition of caspase-3 activation in mutant astrocytes. In addition, we find that hADSCs cocultured with SOD1G93A-bearing astrocytes produce more VEGF, HGF and IGF-1, which are reported to have neuroprotective effects. Our results suggest that hADSCs may be a potential candidate in cellular therapy for ALS. © 2010 Elsevier Inc. All rights reserved.

To generalize the application of Tuina in treating infantile diseases and evaluate the validity and safety of Tuina. By a multicentre randomized controlled study, 240 patients were randomly divided into an observation group (n = 180) and a control group (n = 60). The observation group was treated by tonifying Pijing and clarifying Dachangjing, and Tuina on Lanmen, Qi, Fu Shangqijiegu, Guiwei and Zusanli (ST 36), etc. Banmen and Sanguan were used as the supplementary point according to the syndrome differentiation. The control group was treated by oral administration of Smecta. After 5 day treatments, Chinese syndrome score and the clinical effect were evaluated. After the third and fifth treatment, the Chinese syndrome score of both groups descended obviously. The decline of the observation group was superior to that of the control group (all P < 0.01). The cured rate of 75.6% (136/180) in the observation group was better than 21.7% (13/60) in the control group (P < 0.001). The clinical cured rate of 95.0% (171/180) according to Chinese syndrome score in the observation group was better than 58.3% (35/60) in the control group (P < 0.001). There was no adverse reaction in both groups. Infantile Tuina has a better therapeutic effect in the treatment of acute infantile diarrhea than oral administration of Smecta.

To investigate the role and clinical significance of the expression of BRMS1 gene in development and progression of nasal and paranasal sinus carcinomas. The expression of BRMS1 protein was detected by immunohistochemistry method in the 53 nasal and paranasal sinus carcinomas and 24 nasal polyp tissues and 10 normal mucosa. The expression of BRMS1 was analyzed in nasal and paranasal sinus carcinomas with different clinicopathological parameters. The expression of BRMS1 in normal tissues (90.0%) and nasal polyp tissues (79.2%) was statistically significantly higher than that in nasal and paranasal sinus carcinomas (39.6%) (P < 0.01). There was a positive correlation between BRMS1 expression and TNM staging and lymph node metastasis; but not associated with pathological grade. The loss of BRMS1 expression may be involved in the development and progression of nasal and paranasal sinus carcinomas.

MiRNAs are small, noncoding RNA molecules that act as posttranscriptional regulators of gene expression and function as important regulators in cancer-related processes. The miR-19a is overexpressed in various cancers and has been causally related to cellular proliferation and growth. To determine whether miR-19a plays a role in laryngeal squamous cell carcinoma (LSCC), we used quantitative real time PCR to detect miR-19a expression in LSCC tissues. We found that miR-19a is overexpressed in LSCC and correlated with neck nodal metastasis, poor differentiation and advanced stage. Statistical analysis suggests that higher level of miR-19a was associated with reduced overall survival. In vitro functional study showed that inhibition of miR-19a by antisense oligonucleotides (ASO) led to apoptosis and reduction of cell proliferation in LSCC cells. Furthermore, growth of LSCC xenograft tumors was significantly suppressed by repeated injection of ASO-miR-19a lentivirus. The TUNEL stain and transmission electron microscopy also detected increased apoptotic cells in ASO-miR-19a treated LSCC xenografts. In addition, both realtime PCR and western blot showed ASO-miR-19a can upregulate TIMP-2 expression and this suggests miR-19a is related with TIMP-2 pathway in LSCC cells. Taken together, these data suggest that miR-19a plays an oncogenic role in the progression of LSCC, and may serve as a biomarker or therapeutic target for patients with LSCC.

Background: Hydroxyethyl starch (HES) is one of the most frequently used plasma substitutes, and could modulate inflammatory response in sepsis. Our aim of this study was to investigate the mechanism of the effect of HES 130/0.4 by studying plasma levels of inflammatory cytokines, nuclear factor-κB (NF-κB) activation, and Toll-like receptors (TLRs) expression in peripheral monocytes during polymicrobial sepsis. Materials and Methods: Rats with sepsis induced by cecal ligation and puncture (CLP) were treated with HES130/0.4 (7.5, 15, or 30 mL/kg, intravenously); then, rat plasma and monocytes were isolated from blood 5 h later. The plasma level of cytokines (tumor necrosis factor [TNF]-α and interleukin [IL]-6), NF-κB activity, and mRNA and protein levels of TLRs (TLR2 and TLR4) in peripheral blood monocytes were determined by enzyme-linked immunosorbent assay, electrophoretic mobility shift assay, reverse transcription-polymerase chain reaction, and Western blotting, respectively. Results: HES130/0.4 dose-dependently reduced the plasma level of TNF-α and IL-6 in rats with sepsis. HES130/0.4 also significantly inhibited NF-κB activation, and TLRs mRNA and protein levels in peripheral monocytes. Conclusion: During sepsis, HES130/0.4 can down-regulate the inflammatory response, possibly through inhibition of the TLRs/NF-κB signaling pathway, and could be one more appropriate plasma substitute in sepsis. © 2010 Elsevier Inc.

Background: Personalized medicine should be encouraged because patients are complex, and this complexity results from biological, medical (eg, demographics, genetics, polypharmacy, and multimorbidities), socioeconomic, and cultural factors. Levofloxacin (LVX) is a broad-spectrum fluoroquinolone antibiotic. Awareness of personalized therapeutics for LVX seems to be poor in clinical practice, and is reflected in prescribing patterns. Pharmacokinetic-pharmacodynamic studies have raised concerns about suboptimal patient outcomes with the use of LVX for some Gram-negative infections. Meanwhile, new findings in LVX therapeutics have only been sporadically reported in recent years. Therefore, an updated review on personalized LVX treatment with a focus on pharmacokinetic concerns is necessary. Methods: Relevant literature was identified by performing a PubMed search covering the period from January 1993 to December 2013. We included studies describing dosage adjustment and factors determining LVX pharmacokinetics, or pharmacokinetic-pharmacodynamic studies exploring how best to prevent the emergence of resistance to LVX. The full text of each included article was critically reviewed, and data interpretation was performed. Results: In addition to limiting the use of fluoroquinolones, measures such as reducing the breakpoints for antimicrobial susceptibility testing, choice of high-dose short-course of once-daily LVX regimen, and tailoring LVX dose in special patient populations help to achieve the validated pharmacokinetic-pharmacodynamic target and combat the increasing LVX resistance. Obese individuals with normal renal function cleared LVX more efficiently than normal-weight individuals. Compared with the scenario in healthy subjects, standard 2-hour spacing of calcium formulations and oral LVX was insufficient to prevent a chelation interaction in cystic fibrosis patients. Inconsistent conclusions were derived from studies of the influence of sex on the pharmacokinetics of LVX, which might be associated with sample size and administration route. Children younger than 5 years cleared LVX nearly twice as fast as adults. Patients in intensive care receiving LVX therapy showed significant pharmacokinetic differences compared with healthy subjects. Creatinine clearance explained most of the population variance in the plasma clearance of LVX. Switching from intravenous to oral delivery of LVX had economic benefits. Addition of tamsulosin to the LVX regimen was beneficial for patients with bacterial prostatitis because tamsulosin could increase the maximal concentration of LVX in prostatic tissue. Coadministration of multivalent cation-containing drugs and LVX should be avoided. For patients receiving warfarin and LVX concomitantly, caution is needed regarding potential changes in the international normalized ratio; however, it is unnecessary to seek alternatives to LVX for the sake of avoiding drug interaction with warfarin. It is unnecessary to proactively reduce the dose of cyclosporin or tacrolimus when comedicated with LVX. Transporters such as organic anion-transporting polypeptide 1A2, P-glycoprotein, human organic cation transporter 1, and multidrug and toxin extrusion protein 1 are involved in the pharmacokinetics of LVX. Conclusion: Personalized LVX therapeutics are necessary for the sake of better safety, clinical success, and avoidance of resistance. New findings regarding individual dosing of LVX in special patient populations and active transport mechanisms in vivo are opening up new horizons in clinical practice. © 2014 Gao et al.

The aim of this study is to profile the peripheral biomarkers (tyrosine hydroxylase, TH; interleukin-1β, IL-1β; and tumor necrosis factor-α, TNF-α) for schizophrenia and explore their relations with clinical symptoms. Thirty-nine patients with schizophrenia were evaluated using the Positive and Negative Syndrome Scale (PANSS), and 25 siblings and 30 normal healthy subjects were used as controls. The mRNA expression levels of TH, IL-1β and TNF-α in peripheral blood mononuclear cells, as determined with semi-quantitative reverse transcription-polymerase chain reaction, were all significantly increased in both patients (3-fold) and siblings (2-fold) as compared with normal control. Both IL-1β and TNF-α were significantly correlated with scores on the general psychopathology subscale of the PANSS. A significant positive correlation between IL-1β and TH expression was found in both sibling and normal controls, but not in patients, while a positive correlation between IL-1β and TNF-α was significant in all the groups. These results suggest that TH, IL-1β and TNF-α are overexpressed in the peripheral blood mononuclear cells of schizophrenia patients, perhaps due to the hereditary factors. IL-1β and TNF-α may influence the symptoms of schizophrenia in the cognition dysfunction and anxiety/depression domains of the PANSS. © 2008 Elsevier Ireland Ltd. All rights reserved.

1. Potato pulp is the industrial waste produced during starch extraction from potatoes. Its discharge has become an environmental pollution problem and a decisive cost factor due to stricter environmental legislation and associated expense in the potato starch industry. 2. To date, little information has been provided regarding the nutritive value and any possible toxic effects of potato pulp for poultry feed. 3. In the present paper, a model was developed to assess potato pulp for use as a new poultry feed, which will help starch factories to decrease waste discharge. 4. First, a solid-state fermentation technique to change potato pulp to poultry feed is briefly described; then, the major nutrient compositions of this feed are analysed; lastly, related toxicological effects are studied and the safety of the feed assessed. 5. The results indicated that no unintended effects were found on layer quails during a 30-d feeding study, and the new feed initially showed its safety for poultry in our assessment procedure. However, additional work on limiting nutrients analysis, appetite depressant effects, and egg-laying in a large-scale experiment is required to further establish the findings. © 2010 British Poultry Science Ltd.

To study the changes in the activities of carbon monoxide (CO) and heme oxygenase 2 (HO-2) in ED rats with hyperhomocysteinemia (HHcy). This study included 40 male Wistar rats weighing 280 - 310 g, 10 as normal controls (group A). HHcy models were made in the other 30 by giving 3% methionine for 4 weeks, and then divided into groups B, C and D. The rats in group B continued to be fed with 3% methionine, those in group C were treated with betaine hydrochloride, and those in group D were given zinc porphyrin IX at 45 micromol per kg per d. Penile erections of the rats were recorded, and 4 weeks later, all were killed for determination of the levels of homocysteine (Hcy) in the blood plasma and the activities of CO and HO-2 in the corpus cavernosum of the penis. The level of plasma Hcy, penile erection frequency and the content of CO in the corpus cavernosum were (12.55 +/- 0.82) micromol/L, (1.88 +/- 0.05) times and (10.55 +/- 1.73) micromol/L in group A, the Hcy level significantly higher while the penile erection frequency and CO content remarkably lower than in group B ([25.01 +/- 0.94] micromol/L, [0.70 +/- 0.05] times and [9.51 +/- 1.52] micromol/L, P < 0.05 or P < 0.01), with a negative correlation between the level of Hcy and that of CO and HO-2 (P < 0.01). Compared with group B, the three parameters were all significantly increased in C ([14.37 +/- 0.47] micromol/L, [1.18 +/- 0.08] times and [10.36 +/- 1.56] micromol/L, all P < 0.05 or P < 0.01). Decreased expressions of CO and HO-2 in the corpus cavernosum of the penis may result in ED in HHcy rats. Betaine can reduce the Hcy level in the blood plasma and CO content in the corpus cavernosum, which might be one of the mechanisms of its action on ED with HHcy.
