Dysphagia is a common complication of stroke. Combining the principles of traditional Chinese medicine with modern research findings， it is proposed that "latent pathogen in the cerebral collaterals" constitutes the core pathogenesis of post-stroke dysphagia （PSD）. In clinical practice， treatment is tailored according to the location of PSD. During the oral stage， when the pathogen invades the face and mouth， resulting in excessive salivation， acupoints are primarily selected from the foot shaoyin （少阴） kidney channel， in combination with ren mai （任脉） ， du mai （督脉）， chong mai （冲脉） and the spleen channel， to replenish essence and fill the marrow， dispel dampness and unblock the channels. In the pharyngeal stage， as the pathogen obstructs the throat， disrupting normal swallowing， the therapy emphasizes dredging the shaoyang （少阳） channel and warming and tonifying the jueyin （厥阴） channel， by taking acupoints mainly from the hand and foot shaoyang channels， along with the jueyin channels， so as to soothe the liver and promote bile secretion， regulate and harmonize qi and blood. During the esophageal stage， where the pathogen damages the esophagus， impeding food passage， the treatment emphasizes activating the yangming （阳明） channels and regulating taiyin （太阴） channels； acupoints are mainly selected from the foot yangming stomach channel， along with the taiyin channels， aiming to warm yang， unblock the channels and dispel stasis.

Objective To observe the effectiveness and safety of DiaSphere embolized microsphere TACE for treating primary hepatocellular carcinoma(HCC).Methods Totally 188 patients with HCC were prospectively enrolled and randomly assigned to research group(n=93)and control group(n=95),who underwent TACE with DiaSphere embolized microspheres and Embosphere embolized microspheres,respectively.The incidence of TACE-related adverse events were recorded.The therapeutic efficacy 1 month after the first TACE,also 1 and 3 months after the last TACE,and liver functions 1 month after the first and last TACE were compared between groups.Results In research group,there were 69 cases underwent 1 time TACE,22 cases underwent 2 times and 2 cases underwent 3 times TACE,while in control group,there were 82 cases underwent 1 time and 13 cases underwent 2 times TACE,respectively.No statistical difference of the incidence of adverse events was found between groups(77.42%[72/93]vs.76.84%[73/95],P=1.000).One month after the first TACE,7 cases in research group and 11 cases in control group were lost to follow-up,respectively.One month after the last TACE,12 cases were lost to follow-up in both groups,and 3 months after the last TACE,28 cases were lost to follow-up in both groups.No significant difference of objective response rate nor disease control rate was found between groups at the above time points(all P＞0.05).One month after the first and last TACE,liver function indicators were not different between groups(all P＞0.05).Conclusion Both the short-term efficacy and safety of TACE with DiaSphere embolized microspheres for treating HCC were good.

Objective To study the expression of regulator of cullins-1(ROC1)and ubiquitin binding enzyme 9(UBC9)in non-muscle invasive bladder cancer(NMIBC)and their relationship with clinicopathological features and prognostic value of transurethral resection of bladder tumor(TURBT).Methods Retrospective analysis was conducted on 104 patients with NMIBC who underwent TURBT at Northwest University First Hospital from April 2018 to February 2021.Immunohistochemistry was used to detect the expression of ROC1 and UBC9 in tissues.Follow-up was conducted for 3 years,and Kaplan-Meier curve analysis and COX regression analysis were used to identify factors affecting the prognosis of NMIBC patients.Results The positive rates of ROC1(67.31%)and UBC9(69.23%)in NMIBC cancer tissues were higher than those in adjacent tissues(9.62%,7.69%),and the differences were statistically significant(χ2=73.125,83.200,all P<0.001).There was a positive correlation between the expression of ROC1 and UBC9 in NMIBC cancer(r=0.719,P<0.001).The positivity rates of ROC1(87.23%,90.00%)and UBC9(89.36%,88.33%)in cancer tissues with a maximum tumor diameter of≥2cm,T1 stage were higher than those in cancer tissues with a maximum tumor diameter of<2cm(50.88%,52.63%),Ta/Tis stage(36.36%,43.18%),and the difference were statistically significant(χ2=15.474～33.188,all P<0.05).After TURBT surgery,there were 29 cases of local recurrence,10 cases of metastasis,and 2 deaths of bladder cancer,the 3-year progression-free survival(PFS)rate was 60.58%(63/104).The 3-year PFS of NMIBC patients in the ROC1 positive and negative groups was 47.14%(33/70)and 88.24%(30/34),and the 3-year PFS of patients in the UBC9 positive and negative groups was 47.22%(34/72)and 90.63%(29/32),the differences were statistically significant(Log-rank χ2=15.341,15.931,all P<0.001).Multivariate COX regression analysis showed that ROC1 positivity,UBC9 positivity,maximum tumor diameter≥2cm and T1 phase were risk factors affecting the prognosis of NMIBC patients(all P<0.001).Conclusion The expression of ROC1 and UBC9 is elevated in NMIBC,which is related to the maximum diameter and stage of the tumor.Combined detection of ROC1 and UBC9 can help evaluate the prognosis of NMIBC patients.

Objective:To investigate the efficacy and safety of fluoroscopically-guided percutaneous gastrostomy (FGPG) for establishing enteral nutrition access in the treatment of esophageal fistula after radiotherapy for cervical esophageal cancer (CEC).Methods:A retrospective analysis was conducted on the clinical data of 54 patients who underwent FGPG due to esophageal fistula after radiotherapy for CEC at our department from November 2009 to August 2019. All patients received endoscopy before radiotherapy, and CEC was pathologically confirmed. Enteral nutrition support was offered through a gastrostomy tube postoperatively. The success rate of FGPG, complications, and healing of perforation were recorded and analyzed.Results:FGPG was successfully performed in all 54 patients (100%). During the 12-month follow-up, 50 patients (92.6) survived while four (7.4%) died. Among 36 patients with esophagomediastinal fistula, 32 (88.9%) healed in a median of 12 weeks; of 18 patients with esophagotracheal fistula, 8 (44.4%) healed in a median of 18 weeks. Thus, patients with esophagomediastinal fistula had a significantly higher healing rate ( P<0.01) and shorter healing time ( P=0.017). Gastrostomy tube-related complications were minimal, and no serious complication was noted. Conclusions:FGPG is effective for the treatment of esophageal fistula after CEC radiotherapy and may be an alternative treatment for esophageal fistula.

Based on his extensive clinical experience and the team's mechanistic research, Professor XU Nenggui has proposed the academic concept that "the governor vessel governs the brain and treats cerebral viscus diseases", and established a novel acupuncture approach for encephalopathy treatment centered on the integrated theory of "governor vessel-brain-mind", and developed a staged acupuncture protocol of "governor vessel regulating spirit" for ischemic stroke. This article introduces the academic features of this method in treating post-stroke dysphagia from four aspects: theoretical framework, treatment principles and point selection, mechanistic research, and clinical case studies. In clinical application, the method emphasizes syndrome differentiation based on meridians, harmonization between the conception and governor vessels; precise acupoint selection to treat both form and spirit; stage-specific differentiation with targeted needling. Furthermore, Professor XU integrates basic research with clinical practice, focusing on the neurobiological mechanisms underlying the efficacy of acupuncture in treating post-stroke dysphagia.
