Clinicopathological features and expression of regulatory mechanism of the Wnt signaling pathway in colorectal sessile serrated adenomas/polyps with different syndrome types

BACKGROUND Colorectal cancer(CRC)is the third most common cancer worldwide,with the fourth highest mortality among all cancers.Reportedly,in addition to adenomas,serrated polyps,which account for 15%-30%of CRCs,can also develop into CRCs through the serrated pathway.Sessile serrated adenomas/polyps(SSAs/Ps),a type of serrated polyps,are easily misdiagnosed during endoscopy.AIM To observe the difference in the Wnt signaling pathway expression in SSAs/Ps patients with different syndrome types.METHODS From January 2021 to December 2021,patients with SSAs/Ps were recruited from the Endoscopy Room of Shanghai Traditional Chinese Medicine-Integrated Hospital,affiliated with Shanghai University of Traditional Chinese Medicine.Thirty cases each of large intestine damp-heat(Da-Chang-Shi-Re,DCSR)syndrome and spleen-stomach weakness(Pi-Wei-Xu-Ruo)syndrome were reported.Baseline comparison of the general data,typical tongue coating,colonoscopy findings,and hematoxylin and eosin findings was performed in each group.The expression of the Wnt pathway-related proteins,namelyβ-catenin,adenomatous polyposis coli,and mutated in colorectal cancer,were analyzed using immunohistochemistry.RESULTS Significant differences were observed with respect to the SSAs/Ps size between the two groups of patients with different syndrome types(P=0.001).The other aspects did not differ between the two groups.The Wnt signaling pathway was activated in patients with SSAs/Ps belonging to both groups,which was manifested asβ-catenin protein translocation into the nucleus.However,SSAs/Ps patients with DCSR syndrome had more nucleation,higherβ-catenin expression,and negative regulatory factor(adenomatous polyposis coli and mutated in colorectal cancer)expression(P<0.0001)than SSA/P patients with Pi-Wei-Xu-Ruo syndrome.In addition,the SSA/P size was linearly correlated with the related protein expression.CONCLUSION Patients with DCSR syndrome had a more obvious Wnt signaling pathway activation and a higher risk of carcinogenesis.A high-quality colonoscopic diagnosis was essential.The thorough assessment of clinical diseases can be improved by combining the diseases of Western medicine with the syndromes of traditional Chinese medicine.

Clinical Study on Acupuncture plus Medication for Chronic Atrophic Gastritis Due to Spleen-stomach Deficiency

Objective: To observe the clinical efficacy of combining acupuncture and medication in treating chronic atrophic gastritis(CAG) due to spleen-stomach deficiency. Methods: Totally 176 patients with CAG were randomized into two groups by the random number table. The 91 subjects in the treatment group were intervened by acupuncture and oral Chinese patent medication; the other 85 subjects were by oral Chinese patent medication alone. The clinical efficacies were compared at the end of intervention. Results: After a treatment course, the total effective rate was 87.9% in the treatment group versus 75.3% in the control group; according to the gastroscopy and pathological biopsy examinations, the total effective rate was 85.7% in the treatment group versus 74.1% in the control group. There were significant differences in comparing the clinical efficacy, gastroscopy and pathological examinations between the two groups(P<0.05). Conclusion: Combining acupuncture and medication can produce a better therapeutic efficacy than medication alone in treating CAG due to spleen-stomach deficiency.

Effect of acupoint sticking at Shenque （CV 8） for preventing spleen-stomach disharmony caused by venous analgesia pump

Objective： To observe the clinical effect of acupoint sticking of Chinese medicine at Shenque （CV 8） for preventing spleenstomach disharmony caused by venous analgesia pump. Methods： A total of 120 post-surgery patients using venous analgesia pump and also conforming to the inclusion criteria were randomized into 2 groups by the random number table. There were 58 patients in the control group who received conventional post-surgery nursing care, and there were 62 patients in the treatment group who received acupoint sticking at Shenque （CV 8） on the basis of conventional nursing care. After treatment, the incidences of postoperative nausea and vomiting, and abdominal bloating were measured. Results： The total incidence of nausea, vomiting and abdominal bloating in the treatment group was 11.3%, versus 39.7% in the control group, and the difference of the incidence between the two groups showed a statistical significance （P〈0.05）. In comparison of the severity of spleen-stomach dishormony which happened during 72 h after surgery, cases in the treatment group showed lower severity than those in the control group （P〈0.05）. Conclusion： Acupoint sticking at Shenque （CV 8） can effectively prevent spleen-stomach disharmony caused by venous analgesia pump, which will alleviate sufferings of the patients.
