ABSTRACT

Surgical operation is the main treatment of oral and maxillofacial tumors.Dysphagia is a common postoperative complication.Swal-lowing disorder can not only lead to mis-aspiration,malnutrition,aspiration pneumonia and other serious consequences,but also may cause psychological problems and social communication barriers,affecting the quality of life of the patients.At present,there is no systematic evalua-tion and rehabilitation management plan for the problem of swallowing disorder after oral and maxillofacial tumor surgery in China.Combining the characteristics of postoperative swallowing disorder in patients with oral and maxillofacial tumors,summarizing the clinical experience of ex-perts in the field of tumor and rehabilitation,reviewing and summarizing relevant literature at home and abroad,and through joint discussion and modification,a group of national experts reached this consensus including the core contents of the screening of swallowing disorders,the phased assessment of prognosis and complications,and the implementation plan of comprehensive management such as nutrition management,respiratory management,swallowing function recovery,psychology and nursing during rehabilitation treatment,in order to improve the evalua-tion and rehabilitation of swallowing disorder after oral and maxillofacial tumor surgery in clinic.

ABSTRACT

The olfactory bulb (OB) is the first relay station in the olfactory system. In the OB, mitral/tufted cells (M/Ts), which are the main output neurons, play important roles in the processing and representation of odor information. Recent studies focusing on the function of M/Ts at the single-cell level in awake behaving mice have demonstrated that odor-evoked firing of single M/Ts displays transient/long-term plasticity during learning. Here, we tested whether the neural activity of M/Ts and sniffing patterns are dependent on anticipation and reward in awake behaving mice. We used an odor discrimination task combined with in vivo electrophysiological recordings in awake, head-fixed mice, and found that, while learning induced plasticity of spikes and beta oscillations during odor sampling, we also found plasticity of spikes, beta oscillation, sniffing pattern, and coherence between sniffing and theta oscillations during the periods of anticipation and/or reward. These results indicate that the activity of M/Ts plays important roles not only in odor representation but also in salience-related events such as anticipation and reward.

ABSTRACT

Objective:To explore therapeutic effect of Tanshinone IIA‐sulfonic sodium on patients with coronary heart disease (CHD) and its influence on hemorheology ,cytokines and blood lipid levels .Methods :A total of 98 CHD patients treated in our hospital were selected .According to random number table ,they were randomly and e‐qually divided into routine treatment group and Tanshinone IIA group (received intravenous drip of Tanshinone IIA sulfonate sodium based on routine treatment group ) . Therapeutic effect , hemorheologic indexes , cytokines and blood lipid levels before and after treatment ,and adverse drug reaction were compared between two groups .Re‐sults:Compared with routine treatment group , there was significant rise in total effective rate (73.47% vs . 93.88% ) in tanshinone IIA group ,P=0.003. Compared with before treatment ,after treatment ,there were signif‐icant improvement in levels of blood lipid ,blood viscosity ,and cytokines in Tanshinone IIA group , P< 0.01 all . Compared with routine treatment group after treatment ,there was significant rise in HDL‐C level [ (1.32 ± 0.20) mmol/L vs .(1.74 ± 0.26) mmol/L] ,significant reductions in levels of LDL‐C [(3.27 ± 0.50) mmol/L vs .(2.03 ± 0.29) mmol/L] ,TG [ (2.69 ± 0.48) mmol/L vs .(1.43 ± 0.30) mmol/L] and TC [ (6.89 ± 1.02) mmol/L vs . (4.29 ± 0.71) mmol/L];significant reductions in plasma viscosity [ (2.59 ± 0.61) mPa s vs .(1.45 ± 0.32) mPa s] , whole blood viscosity [(4.63 ± 1.37) mPa s vs .(2.97 ± 0.85) mPa s] ,platelet adhesion rate [(36.73 ± 4.51)% vs . (30.74 ± 3.37)% ] ,levels of Fg [(4.12 ± 0.99) g/L vs .(3.04 ± 0.78) g/L] ,ICAM‐1 [(106.79 ± 30.15) pg/ml vs . (78.43 ± 14.52) pg/ml] ,CRP [(19.98 ± 3.89) mg/L vs .(10.82 ± 2.19) mg/L] and TNF‐α[(27.91 ± 4.78) pmol/L vs .(17.84 ± 3.56) pmol/L] in Tanshinone IIA group ,P<0.01 all .No severe adverse reaction was found in two groups .Conclusion:Tanshinone IIA sulfonate sodium possesses significant therapeutic effect on CHD patients .It can significantly improve patient′s hemorheology ,blood lipid and reduce cytokine levels ,and it′s safe and reliable .

ABSTRACT

Objective To investigate the relationship of androgen receptor (AR) CAG repeat polymorphism and coronary artery disease (CAD) in elderly men and its potential mechanism.Methods Totally 296 elderly men undergoing coronary angiography were enrolled in this study.Serum total testosterone (TT) and free testosterone (FT) levels were measured.Androgen receptors (ARs) in peripheral lymphocytes were determined by flow cytometry.Genome DNA was extracted from peripheral leucocytes using standard techniques.Gene fragments containing AR CAG repeats were amplified by PCR with specific fluorescent labeled primers.PCR products were separated with agarose gels.CAG repeat number of each sample was obtained by genotyping.Results AR CAG repeats varied from 11 to 28 (P25-P75:18-22; median:20) in elderly male patients.They were divided into the long AR group (CAG repeats≥22,n=82) and the short AR group (CAG repeats<22,n=214).Compared with the long AR group,serum FT level was much lower in the short AR group [(24.1±23.1) ×10-6mmol/L vs.(31.2±27.8)×10-6mmol/L,P<0.05].The prevalence of coronary artery disease was higher in the short AR group than in the long AR group [84.1% (180 cases) vs.69.5%(57 cases),P<0.05].The FT level was lower in the short AR group combined with CAD than in the control group [(22.4±20.5) ×10-6mmol/L vs.(33.6±32.4)×10 6mmol/L,P<0.01].There were no significant differences in serum TT and AR levels between the long and short AR groups.No significant correlations were found in the AR CAG repeats polymorphism with FT,TT or AR levels.Age was the main risk factor for FT and AR levels.Logistic regression analysis showed that FT level was negatively correlated with CAD (OR=0.98,95 % CI:0.973-0.998,P=0.01),and short AR increased the risk of CAD in elderly male patients (OR=3.44,95%CI:1.887-6.264,P<0.01).Conclusions Serum FT level is correlated with age and is significantly decreased in elderly male patients with short AR repeats,which may increase the risk of CAD in elderly men.
