Objective To evaluate the clinical effect of ambulatory labor analgesia used in latent phase of the first stage of labor, which include labor progress, Apgar score after ambulatory labor analgesia begun to use when the cervix was different size dilatated. Methods Seventy-five parturient primiparas who had no complication were randomly divided into three groups: group Ⅰ: ambulatory labor analgesia was begun to use when the cervix was 1.0 cm dilated, group Ⅱ: ambulatory labor analgesia was begun to use when the cervix was 2-3 cm dilated, group Ⅲ: control group without use of ambulatory labor analgesia. Analgesic effects were observed, changes of uterine contraction were recorded by fetal monitor. Meanwhile, total stage of labor ,outcome of delivery and Apgar score were recorded. Results Duration of total stage of labor had no significant difference between group Ⅰ and group Ⅲ.The duration of the first labor stage was significantly longer in group Ⅰ than that in group Ⅱ(P

BACKGROUND: Recently, multidrug-resistant (MDR) A. baumannii has been implicated for a significant proportion of nosocominal pneumonia in many intensive care units (ICUs), and its acquisition may increase mortality and the length of stay in the ICU. Aerosolized colistin has been successfully used in patients with cystic fibrosis, but there is a lack of data regarding the use of aerosolized colistin in patients with nosocomial pneumonia. METHODS: We conducted the present study to assess the effectiveness of aerosolized colistin for the treatment of MDR A. baumannii nosocomial pneumonia. We retrospectively reviewed the medical records of 10 patients who had been hospitalized in the medical ICU and had received aerosolized colistin as a therapy for MDR A. baumannii pneumonia. RESULTS: The mean duration of aerosolized colistin therapy was 12.7+/-2.4 days. Nine (90%) of 10 patients showed a favorable response to the therapy. Follow-up cultures were available for all patients, and the responsible pathogen was completely eradicated. One patient suffered from bronchospasm, which resolved after treatment with nebulized salbutamol. CONCLUSION: Our results corroborate previous reports that aerosolized colistin may be an effective and safe choice for the treatment of nosocomial pneumonia caused by MDR A. baumannii. Larger prospective controlled clinical studies are warranted to validate further the effectiveness and safety of aerosolized colistin therapy.

Idiopathic pulmonary fibrosis (IPF) comprises an aggregate of mesenchymal cells. However, the cellular origin of these mesenchymal phenotypes remains unclear. Transforming growth factor beta1 (TGF-beta1) has been known as the main cytokine involved in the pathogenesis of IPF. We examined whether the potent fibrogenic cytokine TGF-beta1 could induce the epithelial-to-mesenchymal transition (EMT) in the human alveolar epithelial cell line, A549, and determined whether snail expression is associated with the phenotypic changes observed in the A549 cells. EMT was investigated with cells morphology changes under phase-contrast microscopy, western blotting, and indirect immunofluorescence stains. E-cadherin and transcription factor, snail, were also evaluated by measuring mRNA levels using reverse transcriptase-polymerase chain rection (RT-PCR) analysis. The data showed that TGF-beta1 induced A549 cells with epithelial cell characteristics to undergo EMT in a concentration-dependent manner. Following TGF-beta1 treatment, A549 cells induced EMT characterized by cells morphological changes, loss of epithelial markers Ecaherin and cytokeratin, increased stress fiber reorganization by F-actin, and cytokeratin replacement by vimentin. Although IL-1beta failed to induce A549 cells to undergo EMT, the combination of TGF-beta1 and IL-1beta showed synergy effects in cells morphology changes and the expression of mesenchymal markers. The snail expression study using RT-PCR analysis provided that loss of E-cadherin expression was associated with snail expression. Stimulation of A54 cells with TGF-beta1 plus IL-1beta revealed a higher level of snail expression. Our data showed that EMT of A549 cells might be closely associated with snail expression.

To examine the efficacy and safety for metformin in treating antipsychotic-induced dyslipidemia.
Methods: Two randomized placebo-controlled trials were included in the analysis. A total of 201 schizophrenia patients with dyslipidemia after treatment with an antipsychotic were collected, and the patients were divided into two groups: a 1 000 mg/d metformin group (n=103) and a placebo group (n=98). The clinical symptoms and metabolic indicators such as body weight, blood glucose, and blood lipids were assessed at baseline, the 12th week and the 24th week after treatment respectively.
Results: After metformin treatment, the mean difference in the low-density lipoprotein cholesterol (LDL-C) value between the metformin group and the placebo group was from 0.16 mmol/L at baseline to -0.86 mmol/L at the end of the 24th week, which was decreased by 1.02 mmol/L
(P<0.01). At the 24th week, the LDL-C was more than 3.37 mmol/L in 25.3% patients in the metformin group, which was significantly lower than that in the placebo group (64.8%) (P<0.01). Compared with the placebo group, there were significant changes in the weight, body mass index (BMI), insulin, insulin resistance index, total cholesterol and triglyceride, and high-density lipoprotein cholesterol (HDL-C) in the metformin group (all P<0.05). The treatment effects on weight and insulin resistance appeared at the 12th week and further improved at the 24th week, but the effects on improving dyslipidemia only significantly occurred at the end of the 24th week.
Conclusion: The metformin treatment is effective in improving antipsychotic-induced dyslipidemia and insulin resistance, and the effect to reduce the antipsychotic-induced insulin resistance appears earlier than the effect to improve dyslipidemia.

Gene therapy represents a promising treatment for the Alzheimer׳s disease (AD). However, gene delivery specific to brain lesions through systemic administration remains big challenge. In our previous work, we have developed an siRNA nanocomplex able to be specifically delivered to the amyloid plaques through surface modification with both CGN peptide for the blood-brain barrier (BBB) penetration and QSH peptide for -amyloid binding. But, whether the as-designed nanocomplex could indeed improve the gene accumulation in the impaired neuron cells and ameliorate AD-associated symptoms remains further study. Herein, we prepared the nanocomplexes with an siRNA against -site amyloid precursor protein-cleaving enzyme 1 (BACE1), the rate-limiting enzyme of A production, as the therapeutic siRNA of AD. The nanocomplexes exhibited high distribution in the A deposits-enriched hippocampus, especially in the neurons near the amyloid plaques after intravenous administration. In APP/PS1 transgenic mice, the nanocomplexes down-regulated BACE1 in both mRNA and protein levels, as well as A and amyloid plaques to the level of wild-type mice. Moreover, the nanocomplexes significantly increased the level of synaptophysin and rescued memory loss of the AD transgenic mice without hematological or histological toxicity. Taken together, this work presented direct evidences that the design of precise gene delivery to the AD lesions markedly improves the therapeutic outcome.
