ABSTRACT
Allergic rhinitis （AR）， a common disease in otolaryngology， is intractable with prolonged attack and greatly affects the daily life of patients. Western medicine adopts many therapeutic protocols， such as medication， immunotherapy， and surgery， and also shows disadvantages， including severe side effects and poor long-term curative effect. As reported by modern research， Chinese medicine has the characteristics of good safety， stable curative effect， multi-target and overall regulation， and has unique advantages in the prevention and treatment of AR. With the increasing clinical practice of Chinese medicine in the treatment of AR， scholars have carried out substantial basic research on the regulation of AR signaling pathways by monomers and Chinese medicinal compounds from molecule-cell-biology. To further explain the transduction mechanism of AR signaling pathways， this paper systematically summarized the research progress based on the studies of monomers and Chinese medicinal compounds to provide references for the in-depth research on the intervention of related signaling pathways by Chinese medicine. The conclusions were drawn as follows. The main signaling pathways involved included nuclear factor-kappa B （NF-κB） signaling pathway， TLR signaling pathway， interleukin （IL）-33/growth stimulation expressed gene 2 （ST2） signaling pathway， phosphoinositide 3-kinase/protein kinase B （PI3K/Akt） pathway， and mitogen-activated protein kinase （MAPK） pathway. As revealed， the signaling pathways involved in the treatment of AR by Chinese medicine interacted with each other and genes were not independent in exerting the effects. For example， TLR， as the upstream signal， affected the PI3K/Akt and MAPK signaling pathways， and NF-κB was the downstream substrate of PI3K/Akt， TLR， IL-33/ST2， and MAPK signaling pathways. It was found that IL-33/ST2， as a new signaling pathway， was correlated with the severity and prognosis of AR.
ABSTRACT
Objective:To evaluate the value of endogenous digitalis-like factor (EDLF) dynamic changes in predicting myocardial injury and prognosis in patients with sepsis.Methods:A total of 160 sepsis patients admitted to the emergency department of Beijing Friendship Hospital Affiliated to Capital Medical University from July 2017 to January 2019 were selected and divided into the myocardial injury(MI) group ( n=75) and the non-myocardial injury (NMI) group ( n=85) according to whether there was myocardial injury. The plasma EDLF concentration was tested on the 1 st, 3 rd and 7 th day after admission. The predictive factors of MI and 90-days outcome were evaluated by logistics regression analysis. Cox proportional hazards regression model was used to estimate the prognostic value of EDLF concentration on the 90 days after admission for sepsis. Results:Septic patients with MI had increased levels of myocardial enzymes, decreased left ventricular fractional shortening index (FS) and interventricular septum (IVS) amplitude and abnormal wall motion, when compared to NMI patients (all P<0.05). EDLF concentration on the 7 th day in the MI group was significantly lower than in the NMI group ( P=0.019). Logistic regression showed that EDLF 7 th was an independent protective factor for MI and 90-day mortality in sepsis respectively ( OR=0.964, 95% CI: 0.934-0.994, P=0.021; OR=0.931, 95% CI: 0.871-0.995, P=0.036). Cox proportional hazards regression analysis suggested that EDLF 7 th concentration <26.7 pmol/L was an independent predictor of 90-day mortality in patients with sepsis ( HR=4.601, 95% CI: 1.030-20.563, P=0.046). Conclusions:EDLF 7 th may serve as a protective factor for sepsis-induced MI and adverse outcome. The exogenous supplement of cardiotonic drugs at one week after MI may be a potential treatment to improve the survival rate of septic patients.
ABSTRACT
Objective To analyze the clinical characteristics and risk factors of myocardial injury (MI) in patients with sepsis.Methods Totally 160 patients with sepsis in April 2016 to December 2017,divided into the MI group and non-MI group.The clinical data laboratory findings and ultrasonic cardiographic findings were recorded and compared between the two groups.Binary logistic regression analysis was performed to find the independent risk factors of/MI in patients with sepsis.Results Total of 160 patients with sepsis 75 (46.9％) patients developed MI.The MI group had older age and more patients with history of hypertension than the non-MI group (P＜0.05).In patients with sepsis,diastolic dysfunction accounted for 84.1％,systolic dysfunction accounted for 4.3％,and ventricular wall dyskinesia accounted for 17.3％.Compared with the non-MI group,the MI group had more abnormal wall motion (9.6％ vs 25.8％,P=0.012),lower interventricular septal amplitude (0.87±0.16 vs 0.80±0.21,P=0.03) and left ventricular posterior wall amplitude (1.03±0.21 vs 0.96±0.18,P=0.034),and decreased fractional shortening (P=0.033).Binary logistic regression analysis showed that age (RR=1.033,P=0.018) and decreased fractional shortening (RR=0.000,P=0.024) were independent risk factors of MI in patients with sepsis.Conclusions Age and decreased fractional shortening were independent risk factors of myocardial injury in patients with sepsis.
ABSTRACT
Objective To investigate the protective effect of transection of cervical sympathetic trunk (TCST) on the noise-induced hearing loss (NIHL) in guinea pigs. Methods Thirty-six guinea pigs were ran-domly divided into three groups (n = 12): the operation group, the sham group and the blank control group. TCST was performed in the operation group , while the cervical sympathetic trunk in the sham group was only ex-posed and separated. The auditory brainstem response (ABR) thresholds was measured. Levels of superoxide dis-mutase (SOD) and malondialdehyde (MDA) in pasma were detected before operation (T0), before noise expo-sure (T1) and on the time of stopping noise exposure (T2), respectively. The damage situation of the outer cochlear hair cells was also checked. Results (1) At the time of T2, ABR thresholds of operation group and sham group were higher than that of the blank control group (P < 0.01), and ABR thresholds of the sham group are higher than the of the operation group (P < 0.05). (2) Levels of SOD and MDA post-noise exposure (T2) were significantly different among the three groups (P < 0.05). (3) Injured hair cells were more serious in the sham group than that in the operation group. Conclusion TCST has protective effect on NIHL in guinea pigs through increasing SOD and decreasing MDA.
ABSTRACT
<p><b>OBJECTIVE</b>To evaluate the influence of small-dose dexmedetomidine infusion on recovery of patients undergoing vertebral operation.</p><p><b>METHODS</b>Sixty ASA I-II patients undergoing vertebral operation were randomly divided into two groups (n=30). In group I, dexmedetomidine infusion was pumped at the rate of 0.5 µg·kg(-1)·h(-1) from tracheal intubation to incision suture, and in group II, 0.9%saline was pumped instead. The mean arterial pressure, heart rate, Riker Sedation-Agitation Scale and Ramesay sedation score were recorded at the time points of autonomous respiration (T1), eye opening (T2), extubation (T3), 1 min after extubation (T4), 10 min after extubation (T5), and 30 min after extubation (T6).</p><p><b>RESULTS</b>The recovery time of autonomous respiration and eye opening time in group I were significantly longer than those in group II, and the extubation time was significantly shorter in group I (P<0.05). Riker Sedation-Agitation Scale scores in group II were significantly higher than those in group I at T2 and T4, and Ramesay sedation scores in group I were significantly higher than those in group II at T1, T2 and T5 (P<0.05). The mean arterial pressure and heart rate at each time point was significantly lower in group I than in group II (P<0.05), especially at T3 and T4 (P<0.01). In both groups, the mean arterial pressure and heart rate at T3 and T4 were significantly higher than those at rest (P<0.05).</p><p><b>CONCLUSIONS</b>Small-dose dexmedetomidine infusion can reduce dysphoria and lower the risks during recovery from general anesthesia following vertebral operation.</p>
