Effect of autoflation on the prognosis of otitis media with effusion in children / 中华耳鼻咽喉头颈外科杂志

Objective: To investigate the effect of autoinflation on the prognosis of OME in children. Methods: Total of 325 pediatric patients, age ranged from 3 to 8 years, with OME(486 ears)diagnosed in our department from January 2019 to January 2020 were collected. Among them, 177 were males, 148 were females. Disease course ranged from 25 to 86 days. According to watchful waiting and autoinflation application during follow-up, these children were divided into two groups including 183 cases(271 ears) and 142 cases(215 ears), respectively. The average auditory threshold and tympanogram curve type in two groups were analyzed in the period of 3 months follow-up, and the recovery of OME was evaluated. Results: At the end of 1- and 2- month follow-up, the auditory threshold of patients in autoinflation group was significantly lower than that in watchful waiting group (t=2.139 5 and 2.680 6, P<0.05). However, at the end of 3- month follow-up, there was no significant difference between two groups (t=1.158 5, P>0.05). At the end of 1-, 2- and 3- month follow-up, 89 (33%, 89/271), 200 (74%, 200/271), 220 (81%, 220/271) and 176 (82%, 176/215), 178 (83%, 178/215), 183 (85%, 183/215) ears in watchful waiting group and autoinflation group had a hearing threshold <20 dB HL, respectively, in which ears with auditory threshold<20 dB HL in watchful waiting group were significantly less than those in autoinflation group at the end of 1 and 2 month follow-up (P<0.05), However, ears with auditory threshold<20 dB HL in watchful waiting group were not significantly different from that in the autoflation group at the end of 3- month follow-up (P>0.05). The proportion of ears with type A tympanogram curve was 74%(159/215), 79%(170/215), and 85%(183/215) at the end of 1-, 2- and 3- month follow-up in autoinflation group and 36%(98/271), 71%(192/271) and 76%(206/271) in watchful waiting group, respectively. Proportion of ears with type A tympanogram curve in autoflation group was significantly higher than that in watchful waiting group (P<0.05). Conclusion: Autoinflation can improve the hearing of children with OME in early stage, restore normal middle ear pressure, increase recovery rate, and reduce the choice of surgical treatment of OME.

The antidepressant effect and mechanism of traditional Chinese formula Yueju Pill based on drug pair / 中国药理学通报

Aim To explore the antidepressant mecha-nism and laws of traditional Chinese formula Yueju Pill by taking drug pair as the breakthrough point. Meth-ods On the basis of anti-depressant activities of Yueju Pill, the combination of different herbs was obtained by the successively disassembling, and the key drug pair was obtained through the acute administration of Yueju Pill in mice. In addition, chronic unpredictable mild stress model was established to further verify the anti-depressant effect of key drug pair, and to explore its molecular mechanism. Results The drug pair of zhizi and chuanxiong was necessary to anti-depression effect of Yueju Pill, and the immobility time of TST and FST was significantly reduced. As expected, the expres-sions of IL-6 and TNF-a and p-NF-kBp65, P-IkBa were obviously lower than those in model group, but the expressions of BDNF and TrkB were up-regulated than those in model group. Conclusions The drug pair of zhizi and chuanxiong is necessary for traditional Chinese formula Yueju Pill for the antidepressant effect. It is assumed that the antidepressant effect and mechanism of zhizi and chuanxiong are connected with cytokine IL-6, TNF-a and protein expressions of p-NF-kBp65, P-IkBa, and BDNF.
