So far, modern medicine has not find an effective way to tackle this problem. Several studies suggest acupoint-injection may be applied to the treatment of pseudobulbar paralysis(PBP).However, current evidence is not enough to prove its efficacy. Therefore,this pilot study was desgined to certificate the feasibility and&nbsp; validity&nbsp; of&nbsp; Xingnaojing&nbsp; acupoint-injection&nbsp; at&nbsp; (XNJ-AI)&nbsp; Fengchi(GB20)&nbsp; for&nbsp; treatment&nbsp; of pseudobulbar paralysis caused by ischemic stroke (PBP-IS).&nbsp; Methods: This study was an assessorblinded ,two-parallel-group, randomized controlled trial. Participants with (PBP-IS) was recruited and randomly divided into two groups .Participants in the controll group received the oral aspirin (one&nbsp; 100mg&nbsp; tablet&nbsp; once&nbsp; a&nbsp; day&nbsp; for&nbsp; two&nbsp; weeks)&nbsp; .In&nbsp; addition&nbsp; to&nbsp; the&nbsp; oral&nbsp; aspirin&nbsp; ,patients&nbsp; in&nbsp; the treatment group received Xingnaojing acupoint-injection(XNJ-AI) at Fengchi (GB20) (once a day for&nbsp; two&nbsp; weeks).Measures&nbsp; was&nbsp; taken&nbsp; before&nbsp; and&nbsp; after&nbsp; treatments.&nbsp; The&nbsp; primary&nbsp; outcome&nbsp; was assessed by the Kubota water experiment. The secondary outcome was to measure the TXB2and 6-keto-PGF1a.&nbsp; <strong>Results</strong>:&nbsp; We&nbsp; observed&nbsp; a&nbsp; significantly&nbsp; greater&nbsp; improvement&nbsp; in&nbsp; swallowing function(P&lt;0.05),and an obvious drop in the TXB2 values(P&lt;0.05) with a remarkable rise in the 6-keto-PGF1a values(P&lt;0.05).<strong>Conclusion</strong>: XNJ-AI at GB20 may improve the patients’ swallowing function and balance the TXB2and 6-keto-PGF1a.</p><p><strong>Key&nbsp; words</strong>:&nbsp; Acupuncture&nbsp; and&nbsp; moxibustion,&nbsp; Xingnaojing,&nbsp; Acupoint-injection,&nbsp; Pseudobulbar paralysis, Swallowing function, TXB2,6-keto-PGF1a</p><p><br/></p>
