Objective To evaluate the efficacy and safety of the loratadine paracetamol and pseudoephedrine(LPP)sustained-release tablets in the treatment of common cold and influenza compared with compound pseudoephedrine hydrochloride tablets.Methods Multi-center,randomized,double-blinded controlled clinical trial.One hundred eighteen patients were given LPP sustained-release tablets as trial group,119 were given pseudoephedrine hydrochloride as control group.Results Non-inferiority statistics showed that the improvement rate of clinical symptoms in trial group were not lower than that in control group(P<0.05).The total symptom score did not differ in trial group and control group(P>0.05).The effective rate in trial group and control group were 96.33% and 96.36%(P>0.05).The incidence of adverse drug reactions in trial group and control group was 7.02% and 11.82%,respectively(P>0.05).Conclusion LPP sustained-release tablets is effective and safe in the treatment of common cold and influenza.

Objective To provide theoretical reference for the research on lateral postural control in older people by using the electromyography （EMG）technique to compare the neuromuscular reaction between the young and older people during lateral perturbation. Methods Postural reactions of 14 young people and 14 older people as subjects were evoked by sudden unpredictable medio lateral translation platform. The surface EMG data were collected from peroneus longus, anterior tibialis, gluteus medius and erector spinae of the left side of the body. Results The latencies in anterior tibialis, gluteus medius and erector spinae were obviously delayed in older people, and the duration of time to peak in peroneus longus, anterior tibialis and gluteus medius of older people was much longer than that of young people. Conclusions The delayed response of ankle, hip and trunk muscle and the low efficacy of contraction rate in ankle and hip muscles to the unexpected perturbation might be the primary reason for the decrease of lateral postural control in older people.

Central sensitization is essential in maintaining chronic pain induced by chronic pancreatitis (CP), but cortical modulation of painful CP remains elusive. Here, we examined the role of the anterior cingulate cortex (ACC) in the pathogenesis of abdominal hyperalgesia in a rat model of CP induced by intraductal administration of trinitrobenzene sulfonic acid (TNBS). TNBS treatment resulted in long-term abdominal hyperalgesia and anxiety in rats. Morphological data indicated that painful CP induced a significant increase in FOS-expressing neurons in the nucleus tractus solitarii (NTS) and ACC, and some FOS-expressing neurons in the NTS projected to the ACC. In addition, a larger portion of ascending fibers from the NTS innervated pyramidal neurons, the neural subpopulation primarily expressing FOS under the condition of painful CP, rather than GABAergic neurons within the ACC. CP rats showed increased expression of vesicular glutamate transporter 1, and increased membrane trafficking and phosphorylation of the N-methyl-D-aspartate receptor (NMDAR) subunit NR2B and the α-amino-3-hydroxy-5-methyl-4-isoxazole propionic acid receptor (AMPAR) subunit GluR1 within the ACC. Microinjection of NMDAR and AMPAR antagonists into the ACC to block excitatory synaptic transmission significantly attenuated abdominal hyperalgesia in CP rats, which was similar to the analgesic effect of endomorphins injected into the ACC. Specifically inhibiting the excitability of ACC pyramidal cells via chemogenetics reduced both hyperalgesia and comorbid anxiety, whereas activating these neurons via optogenetics failed to aggravate hyperalgesia and anxiety in CP rats. Taken together, these findings provide neurocircuit, biochemical, and behavioral evidence for involvement of the ACC in hyperalgesia and anxiety in CP rats, as well as novel insights into the cortical modulation of painful CP, and highlights the ACC as a potential target for neuromodulatory interventions in the treatment of painful CP.
